PROSPECTUS SUPPLEMENT SUMMARY

This summary is not complete and does not contain all of the information that you should consider before investing in the securities offered by this prospectus. You should read this summary together with the entire prospectus supplement and the accompanying prospectus, including our financial statements, the notes to those financial statements and the other documents that are incorporated by reference in this prospectus supplement and the accompanying prospectus, before making an investment decision.

Kratos Defense & Security Solutions, Inc.

Our Business

Kratos is an innovative provider of mission-critical engineering, information technology services, strategic communications and warfighter products, solutions and services. We work primarily for the U.S. government and federal government agencies, but we also perform work for state and local agencies and commercial customers. Our principal services are related to, but are not limited to, Command, Control, Communications, Computing, Combat Systems, Intelligence, Surveillance and Reconnaissance ("C5ISR"); weapons systems lifecycle support and sustainment; military weapon range operations and technical services; missile, rocket and weapons system testing and evaluation; missile and rocket mission launch services; public safety, security and surveillance systems; modeling and simulation; unmanned aerial vehicle systems; and advanced network engineering and information technology services. We offer our customers solutions and expertise to support their mission-critical needs by leveraging our skills across our core service areas.

We derive a substantial portion of our revenue from contracts performed for federal government agencies, including the U.S. Department of Defense ("DoD"), with substantially all of our revenue currently generated from the delivery of mission-critical warfighter solutions, advanced engineering services, system integration and system sustainment services to defense and other non-DoD and civilian government agencies. We believe our stable client base, strong client relationships, broad array of contract vehicles, considerable employee base possessing government security clearances, extensive list of past performance qualifications, and significant management and operational capabilities position us for continued growth.

Prior to 2008, we were also an independent provider of outsourced engineering and network deployment services, security systems engineering and integration services and other technical services for the wireless communications industry, the U.S. government and enterprise customers. In 2006 and 2007, we undertook a transformation strategy whereby we divested our commercial wireless-related businesses and chose to pursue business with the federal government, primarily the DoD, through strategic acquisitions. On September 12, 2007, we changed our name from Wireless Facilities, Inc. to Kratos Defense & Security Solutions, Inc. Our new name reflects our revised focus as a defense contractor and security systems integrator for the federal government and for state and local agencies. In connection with our name change, we changed our NASDAQ Global Select Market trading symbol to "KTOS".

Competitive Strengths

We believe we have robust past performance qualifications in our respective business areas, including a work force that is experienced with the various programs we service and the customers we serve. We believe the following key strengths distinguish us competitively:

•

Significant and highly specialized experience.  Through existing customer engagements and the government-focused acquisitions we have completed over the past several years, we have amassed significant and highly specialized experience in areas directly related to weapon system life-cycle extension and sustainment; missile, rocket and weapons system testing and evaluation; C5ISR;

S-1

---

Table of Contents

military range operations and technical services, and other highly differentiated services and solutions. This collective experience, or past performance qualifications, is a requirement for the majority of our contract vehicles and customer engagements. Further enhancing our specialized expertise, a majority of our over 2,800 employees have national security clearances. We believe these characteristics represent a significant competitive strength and position us to win renewal or follow-on business.

•

Specialized national security focus aligned with mission-critical national security priorities.  Continued concerns related to the threat posed by certain foreign nations and terrorists have caused the U.S. government to identify national security as an area of functional and spending priority. Budget pressures, particularly related to DoD spending, have placed a premium on developing and fielding relatively low-cost, high-technology solutions to assist in national security missions. Our primary capabilities and areas of focus, listed below, are strongly aligned with the objectives of the U.S. government:

•

Intelligence, surveillance and reconnaissance

•

Command and control

•

Unmanned systems

•

Ballistic missile defense

•

Cyber security and information assurance

We believe our strategy has been confirmed through our established positions on 11 of the top 15 DoD programs in terms of total procurement and research, development, testing and evaluation spending, including the F-35 Lightning II, multiple missile defense programs, Bridge Combat Team (Future Combat Systems), multiple unmanned aerial vehicle ("UAV") programs, Blackhawk helicopter and related variants, CVN-21 Carrier Replacement, DDG-51 Aegis Destroyer, Littoral Combat Ship and others.

•

Strategic geographic locations and base realignment and closure.  The U.S. Base Realignment and Closure Act of 2005 ("BRAC") is the congressionally authorized process the DoD has implemented to reorganize its base structure to fewer, larger bases in order to support U.S. armed forces more efficiently and effectively, increase operational readiness and facilitate new ways of doing business. As a result of the DoD's BRAC transformation, we have concentrated part of our business strategy on building a significant presence in key BRAC receiving locations where the U.S. federal government is relocating its personnel and related technical and professional services. We believe our focus on increasing our strategic presence in key BRAC receiving locations will provide us with a significant competitive advantage.

•

Diverse base of key contracts with low concentration.  As a result of our business development focus on securing key contracts, we are a preferred contractor on numerous multi-year, government-wide acquisition contracts and multiple award contracts. Our preferred contractor status provides us with the opportunity to bid on hundreds of millions of dollars of business each year against a discrete number of other pre-qualified companies. We have a highly diverse base of contracts with no contract representing more than 5% of pro forma 2009 revenue. Our fixed-price contracts, almost all of which are production contracts, represent approximately 54% of our pro forma 2009 revenue. Our cost-plus-fee contracts and time and materials contracts represent approximately 24% and 22%, respectively, of our pro forma 2009 revenue. We believe our diverse base of key contracts and low reliance on any one contract provides us with a stable, balanced revenue stream.

•

In-depth understanding of client missions.  We have a reputation for providing mission-critical services and solutions to our clients. Our relationships with our U.S. Army, U.S. Navy and U.S. Air Force customers generally exceed 10 years, enabling us to develop an in-depth understanding of their missions and technical needs. In addition, we have employees located at customer sites, providing us

S-2

---

Table of Contents

valuable strategic insights into our clients' ongoing and future program requirements. Our in-depth understanding of our clients' missions, in conjunction with the strategic location of our employees, enables us to offer technical solutions tailored to our clients' specific requirements and evolving mission objectives. In addition, once we are on-site with a customer, we have historically been successful in winning recompete business in the vast majority of cases.

•

Significant cash flow visibility driven by stable backlog.  As of September 26, 2010, our pro forma total backlog was approximately $883 million, of which approximately $508 million was funded backlog. The majority of our sales are from orders issued under long-term contracts, typically three to five years in duration. Our contract backlog provides visibility into stable future revenue and cash flow over a diverse set of contracts.

•

Highly skilled employees and an experienced management team.  We deliver our services through a skilled workforce of over 2,800 employees. Our senior managers have significant experience with U.S. federal government agencies, the U.S. military and federal government contractors. Members of our management team have experience growing businesses both organically and through acquisitions. We believe that the cumulative experience and differentiated expertise of our personnel in our core focus areas, coupled with our sizable employee base, the majority of which hold national security clearances, allow us to qualify for and bid on larger projects in a prime contracting role.

Pending Acquisition of Herley Industries, Inc.

Overview of the Acquisition

On February 7, 2011, we entered into a merger agreement to acquire Herley Industries, Inc., a Delaware corporation ("Herley"), through a tender offer by one of our indirect wholly-owned subsidiaries for all of Herley's outstanding common stock and a subsequent merger between such subsidiary and Herley. See "— Terms of Acquisition and Related Financing Transactions — Merger Agreement." Since the completion of the acquisition of Herley is subject to various conditions, it is not certain that we will acquire Herley within the expected timeframe or at all. Failure to complete the acquisition of Herley could adversely affect our stock price and our future business or financial results and would affect the use of proceeds from this offering. See "Risk Factors — Risks Related to the Proposed Acquisition of Herley" and "Use of Proceeds".

Overview of Herley's Business

Herley is a leading provider of microwave technologies for use in command and control systems, flight instrumentation, weapons sensors, radar, communication systems, and electronic warfare systems. Herley has served the defense industry since 1965 by designing and manufacturing microwave devices for use in high-technology defense electronics applications. Herley's products represent key components in the national security efforts of the U.S., as they are employed in mission-critical electronic warfare, electronic attack, electronic warfare threat and radar simulation, command and control network, and cyber warfare/cybersecurity applications.

We believe Herley represents a premier source for RF and microwave electronics due to its end-to-end product capability across its core end markets. In addition, Herley provides significant value to its customers through its ability to create innovative, high-performance products and solutions for a broad array of applications ranging from standard, high-production components to custom, complex integrated subsystems.

Herley has developed a defensible market position through its engineering expertise and technological capabilities, long development cycle (including interaction with customers during pre-production design), high risk and cost to customer to replace its components and systems and 45+ year track record of expertise in the microwave industry. Herley has leveraged these qualities to create entrenched positions on leading defense platforms, with the majority of its revenue being derived from single-source assignments. As

a result, Herley offers significant visibility into future revenue and profitability with its long-term status on many well-funded platforms.

Herley has established long-term relationships with its primary customers, including large defense prime contractors (including Northrop Grumman Corporation, Lockheed Martin Corporation, Raytheon Company, The Boeing Company and BAE Systems), the U.S. government (including the DoD, NASA and other U.S. government agencies) and international customers (including the Israeli and Australian militaries and suppliers to international militaries). Herley's products and systems are currently deployed on a wide range of high profile military platforms, including the F-16 Falcon, the F/A-18E/F Super Hornet, the E-2C/D Hawkeye, the EA-18G Growler, the AEGIS class surface combatants, the EA-6B Prowler, the AMRAAM (Advanced Medium-Range Air-to-Air Missile), the CALCM (Conventional Air Launch Cruise Missile), the P-8 MMA (Multi-Mission Maritime Aircraft) and UAVs, as well as high priority national security programs such as National Missile Defense and the Trident II D-5.

Strategic Rationale

We believe that the proposed acquisition will provide long-term strategic and financial benefits to our stockholders, including long-term growth in revenues, earnings and returns on equity, and will offer other important benefits including:

•

Strong fit with our existing core competencies.  Herley's business is primarily focused on providing mission-critical products for national security and weapons systems applications on which we are working, which we are supporting or with which we are familiar, including:

•

Manned and unmanned aircraft

•

Tactical and ballistic missiles

•

Sensor and radar platforms

•

Representative threat targets

•

Simulation and testing

•

Electronic warfare systems

•

Electronic attack systems

•

Command and control systems

•

Long-term positions on high-priority, well-funded military platforms.  Herley's existing products primarily support fielded systems on established, solidly-funded programs that will be deployed by the U.S. and foreign militaries for the foreseeable future. Examples of these platforms, which support electronic attack, electronic warfare, radar/threat simulation and threat neutralization missions, include: F-16, EA-18G, AMRAAM, F-18 and Trident.

•

Acquisition of a scarce asset with a strong reputation in its markets.  Herley represents one of the few remaining independent electronic warfare/electronic attack-focused companies. Herley experiences limited competition due to the nature of its work and benefits from high barriers to market entry from potential competitors. For these reasons and as a result of its strong intellectual property profile, Herley has created sole-source or single-source positions on the majority of its contracts.

•

Strong growth opportunities.  Herley maintains a substantial new business pipeline with opportunities in multiple areas, including:

•

Next Generation Intelligence, Surveillance and Reconnaissance Airborne System

•

Unmanned Autonomous Air Vehicles

•

UAS System for Persistent ISR Data Collection

•

Electronic Warfare Jammers — Next Generation

•

Electronic Attack — Next Generation

•

Electronic Cyber Attack

•

Foreign Military Sales and Direct International Sales

Table of Contents

•

Ease of integration with our existing business.  We expect Herley to be easily integrated into our Weapon Systems Solutions ("WSS") Division. The WSS Division houses our work on weapons and other platforms similar to Herley's business, including manned and unmanned aircraft targets, sensors and radar platforms, and tactical and ballistic missiles. All six key Herley division Presidents are expected to continue their employment with us to ensure a smooth transition and continued success.

•

Diversification of business.  Our acquisition of Herley would allow us to add premier microwave components and systems to our existing services offerings. Herley supplies its products to many of our existing platforms, which would allow us to enhance our exposure to key programs. We believe Herley would be able to introduce new products and services on each of its and our existing platforms. In addition, we believe creating a broader solutions portfolio would create many attractive opportunities on new programs. In addition, Herley maintains a diversified revenue base as it is a direct supplier to all services of the U.S. military and a first-tier supplier to all of the primary defense contractors. In addition, Herley's products are embedded on over 120 individual platforms, with no one program comprising more than 8% of its total revenue.

•

Significant profitability enhancement.  In recent periods, Herley's EBITDA margins have been approximately twice our EBITDA margins. The proposed acquisition would substantially enhance our profitability profile.

•

Opportunities to achieve significant synergies.  Herley will be integrated directly into our WSS Division. Upon completion of the acquisition, management expects that each Herley division and facility will report directly to the President of our WSS Division, resulting in cost efficiencies. In addition, upon completion of the acquisition, Herley will no longer require expenses related to operating as a publicly traded company, including directors' compensation, related insurance, audit fees and fees and expenses related to public filings. We expect the removal of these costs will eliminate approximately $5 million annually in operating expenses from Herley, of which approximately $2 million on an annualized basis will be eliminated starting in the first quarter following completion of the acquisition of Herley and $3 million on an annualized basis will be eliminated during the remainder of the 12-month period following completion of the acquisition.

Terms of Acquisition and Related Financing Transactions

Merger Agreement

On February 7, 2011, we entered into an Agreement and Plan of Merger (the "Merger Agreement") with Lanza Acquisition Co., a Delaware corporation and our indirect wholly-owned subsidiary ("Merger Sub"), and Herley. The boards of directors of Kratos and Herley have approved the Merger Agreement and the transactions contemplated thereby. Pursuant to the terms of the Merger Agreement, Merger Sub will commence a tender offer (the "Offer") to purchase all of Herley's issued and outstanding shares of common stock, par value $0.10 per share (the "Herley Common Stock"), at a price of $19.00 per share in cash, without any interest thereon (the "Offer Price"). Merger Sub is obligated to commence the Offer as promptly as practicable and in any event no later than February 25, 2011. The Offer will remain open for 20 business days, subject to periods of extension through June 30, 2011 if the conditions to the Offer have not been satisfied at the end of any Offer period (subject to the parties' termination rights under the Merger Agreement).

The consummation of the Offer is subject to customary closing conditions, including, among other things, the expiration of all applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and, subject to the terms of the Merger Agreement, any other applicable competition laws and the valid tender of shares of Herley Common Stock representing at least a majority of the total outstanding shares of Herley Common Stock, calculated on a fully diluted basis, and other offer conditions set forth in Annex A to the Merger Agreement.

Table of Contents

Upon completion of the Offer, and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, Merger Sub will be merged (the "Merger") with and into Herley, with Herley surviving as a wholly-owned subsidiary of ours. At the effective time of the Merger (the "Effective Time"), each outstanding share of Herley Common Stock, other than shares of Herley Common Stock owned by Merger Sub, Kratos or any of its subsidiaries or Herley or any of its subsidiaries immediately prior to the Effective Time, or by stockholders who have validly exercised their appraisal rights under Delaware law, will be canceled and converted into the right to receive an amount in cash equal to the Offer Price payable to the holder thereof, on the terms and subject to the conditions set forth in the Merger Agreement. In addition, at the Effective Time, (i) at the election of the holder thereof, each in-the-money option to purchase Herley Common Stock will be canceled and exchanged for a cash payment equal to: (a) the excess, if any, of the Offer Price over the per share exercise price of such in-the-money option, multiplied by (b) the number of shares subject to such in-the-money option; (ii) all other options to purchase Herley Common Stock shall be assumed by us (the "Assumed Options") and shall thereafter represent an option to purchase a number of shares of our common stock, with such number of shares of our common stock subject to and the exercise price applicable to such option being appropriately adjusted based on an exchange ratio equal to the fraction obtained by dividing the Offer Price by the average closing sales price for one share of our common stock on the NASDAQ Global Select Market for the ten (10) trading-day period ending on the first business day immediately preceding the date of the Merger Agreement; and (iii) each restricted stock award granted under any compensation plan or arrangement of Herley and outstanding immediately prior to the Effective Time shall be cancelled at the Effective Time in exchange for the merger consideration payable in respect of such stock.

The closing of the Merger is subject to, among other conditions, the adoption of the Merger Agreement by holders of a majority of the outstanding shares of Herley Common Stock, if required by applicable law. However, the Merger Agreement also provides that, subject to certain conditions and limitations, Merger Sub will have an irrevocable option (the "Top-Up Option"), exercisable after the completion of the Offer, to acquire a number of shares of Herley Common Stock equal to the lesser of (i) the lowest number of shares that, when added to the number of shares of Herley Common Stock owned by us or Merger Sub at the time of the exercise of the Top-Up Option, will constitute one share more than 90% of the number of shares of Herley Common Stock that will be outstanding after giving effect to the exercise of the Top-Up Option, at a price per share equal to the Offer Price, and (ii) the aggregate number of shares held as treasury shares by Herley and the number of additional shares that Herley is authorized to issue under its certificate of incorporation. The Top-Up Option is intended to expedite the timing of the completion of the Merger by permitting the Merger to occur without a meeting of the Herley stockholders pursuant to the "short-form merger" provisions of the Delaware General Corporation Law.

Kratos, Herley and Merger Sub have made customary representations, warranties and covenants in the Merger Agreement. Herley's covenants include, among other things, covenants regarding the operation of the business prior to the closing and covenants prohibiting Herley from soliciting, providing information to third parties in connection with or entering into discussions concerning, proposals relating to alternative business combination transactions, except in limited circumstances relating to unsolicited proposals that would reasonably constitute, or would reasonably be expected to lead to, a proposal superior to the transactions contemplated by the Merger Agreement.

The Merger Agreement contains certain termination rights for each of Herley and Kratos. In addition, upon the termination of the Merger Agreement under specified circumstances, Herley will be required to pay us a termination fee in an amount equal to $9,440,000.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, a copy of which is attached hereto as Annex A.

Financing Transactions

We estimate our cash requirements in connection with the acquisition of Herley to be approximately $318 million. On February 7, 2011, in connection with the Offer, we entered into a commitment letter (the "Commitment Letter") with Jefferies Group, Inc., Key Capital Corporation and OPY Credit Corp. (collectively, the "Committing Parties"), pursuant to which the Committing Parties have committed to provide debt financing of up to an aggregate of $307.5 million for the Offer. The amount of the commitment is subject to reduction by the amount of net proceeds that we raise in this offering; provided that the maximum amount of such reduction shall not exceed $40 million. The commitment of the Committing Parties under the Commitment Letter is subject to customary conditions, including the absence of any material adverse effect on the financial condition of Herley or our ability to consummate the transactions described in the Commitment Letter. We intend to commence a private offering to eligible purchasers, subject to market and other conditions, of up to $325 million in aggregate principal amount of senior secured notes due 2017 (the "New Notes"). This prospectus supplement does not constitute an offer to sell or the solicitation of an offer to buy the New Notes and shall not constitute an offer, solicitation or sale in any jurisdiction in which such offering, solicitation or sale would be unlawful.

In connection with the offering of the New Notes, we have received the consent of the holders of a majority of our existing 10% Senior Secured Notes due 2017 (the "Existing Notes") and have entered into a supplemental indenture related to the Existing Notes in which such holders agreed to permit us to issue the New Notes in an aggregate principal amount not to exceed $325 million in connection with the acquisition of Herley and for general corporate purposes irrespective of whether such New Notes may be issued in compliance with the minimum consolidated fixed charge coverage ratio test contained in the limitation of incurrence of additional indebtedness covenant in the indenture governing the Existing Notes. In addition, we have entered into an amendment to our existing senior secured credit agreement (the "Credit Agreement") with KeyBank National Association ("KeyBank"), pursuant to which KeyBank has agreed to waive any restrictions in the Credit Agreement with respect to the acquisition of Herley and the issuance of the New Notes. Wilmington Trust FSB and KeyBank also entered into an amendment to the existing intercreditor agreement to make certain changes to such agreement so as to permit the consummation of the acquisition of Herley.

We expect to use the net proceeds from this offering together with the net proceeds from the issuance and sale of the New Notes (and to the extent the Notes are not issued and sold, the debt financing to be provided by the Committing Parties, subject to the satisfaction of the conditions of the Commitment Letter) to fund the purchase of the Herley Common Stock in connection with the acquisition of Herley and for other general corporate purposes. If the acquisition of Herley is not completed, we will use the net proceeds from this offering for general corporate purposes. See "Use of Proceeds".

As presented in the table below, Adjusted EBITDA is a non-GAAP financial measure defined as GAAP income (loss) from continuing operations plus, interest expense, net, provision (benefit) for income taxes, depreciation and amortization, stock-based compensation expense, impairment of goodwill, stock option investigation and related fees and certain recovery and settlement amounts, and other (income) expense related to interest rate swap agreements.

Adjusted EBITDA as calculated by us may be calculated differently than EBITDA for other companies. We have provided Adjusted EBITDA because we believe it is a commonly used measure of financial performance in comparable companies and is provided to help investors evaluate companies on a consistent basis, as well as to enhance an understanding of our operating results. Our management uses these non-GAAP financial measures along with the most directly comparable GAAP financial measures in evaluating our operating performance and capital resources and cash flow. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information presented in compliance with GAAP, and non-GAAP financial measures as reported by us may not be comparable to similarly titled amounts reported by other companies. Adjusted EBITDA should not be construed as either an alternative to net income or as an indicator of our operating performance or an alternative to cash flow as a measure of liquidity.

Summary Unaudited Pro Forma Condensed Combined Consolidated
Financial and Operating Information

The following table sets forth summary unaudited pro forma condensed combined consolidated financial information of Kratos. The summary unaudited pro forma condensed combined financial data is intended to show how the acquisition of Herley might have affected historical financial statements of Kratos if such acquisition had been completed at an earlier time and was prepared based on the historical financial results reported by Kratos and Herley. The following should be read in connection with the audited and unaudited consolidated financial statements of Herley, set forth in Annex B of this prospectus supplement, and our audited and unaudited consolidated financial statements which are incorporated by reference into this prospectus supplement. See "Where You Can Find Additional Information" beginning on page S-61.

The summary unaudited pro forma condensed combined financial statements were prepared in accordance with the regulations of the SEC. The pro forma adjustments reflecting the completion of the acquisition of Herley are based upon the acquisition method of accounting in accordance with GAAP, and upon the assumptions set forth in the notes to the unaudited pro forma condensed combined financial statements.

During 2010, Kratos acquired Gichner Holdings, Inc. ("Gichner") and Henry Bros. Electronics. Inc. ("HBE"). The acquisition of each of Gichner and HBE was completed on May 19, 2010 and December 15, 2010, respectively.

The summary unaudited pro forma condensed combined balance sheet as of September 26, 2010 combines the historical consolidated balance sheets of Kratos as of September 26, 2010, HBE as of September 30, 2010, and Herley as of October 31, 2010.

The summary unaudited pro forma condensed combined statements of operations for the nine months ended September 26, 2010 combine the historical consolidated statements of operations of Kratos, Herley and HBE for their respective nine months ended September 26, 2010, October 31, 2010 and September 30, 2010, and of Gichner for the three months ended March 31, 2010. The summary unaudited pro forma condensed combined statements of operations for the year ended December 27, 2009 combine the historical consolidated statements of operations of Kratos, Gichner and HBE for their respective years ended December 27, 2009, December 31, 2009 and December 31, 2009, and of Herley for the 12-month period ended January 31, 2010. The operating results for the 12-month period ended January 31, 2010 for Herley were derived from the quarterly operating results and annual operating results of Herley.

The unaudited pro forma condensed combined financial information also gives effect to this offering and the related debt financing.

The summary unaudited pro forma condensed combined consolidated financial information is provided for illustrative purposes only and does not purport to represent what Kratos' actual consolidated results of operations or the consolidated financial position would have been had the transactions occurred on the dates assumed, nor are they necessarily indicative of future consolidated results of operations or consolidated financial position.

RISK FACTORS

An investment in our common stock involves a substantial risk of loss. You should carefully consider these risk factors, together with all of the other information included or incorporated by reference in this prospectus supplement and the accompanying prospectus, as modified and superseded pursuant to Rule 412 under the Securities Act, before you decide to invest in our common stock. The occurrence of any of the following risks could harm our business. In that case, the trading price of our common stock could decline, and you may lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our operations. You should also refer to the other information contained in this prospectus supplement and the accompanying prospectus or incorporated by reference herein or therein, including our financial statements and the notes to those statements and the information set forth under the heading "Cautionary Note Regarding Forward-Looking Statements."

Risks Related to the Proposed Acquisition of Herley

The proposed acquisition of Herley may not be completed within the expected timeframe, or at all, and the failure to complete such acquisition could adversely affect our stock price and our future business and financial results.

On February 7, 2011, we entered into the Merger Agreement with Herley. The Merger Agreement is an executory contract subject to numerous closing conditions beyond our control, and there is no guarantee that these conditions will be satisfied in a timely manner or at all. If any of the conditions to the proposed Merger are not satisfied (or waived by the other party), we may not complete the Merger or realize the anticipated benefits thereof. Disputes regarding interpretations of the Merger Agreement could also delay or prevent the closing. In addition, the market price of our common stock may reflect various market assumptions as to whether and when the proposed Merger will occur. Consequently, the failure to complete the Merger within the expected timeframe, or at all, could result in a significant change in the market price of our common stock.

The offering of common stock pursuant to this prospectus supplement is not conditioned on the completion of the proposed Merger.

The offering of common stock pursuant to this prospectus supplement is not conditioned on completion of the proposed Merger. Although certain information contained in this prospectus supplement generally assumes the completion of the Merger, we cannot assure you that the Merger will be consummated on the terms described in this prospectus supplement or at all. If we do not complete the proposed Merger, we will retain broad discretion to use the net proceeds from this offering of common stock for general corporate purposes, including the acquisition of or investment in other businesses, services and technologies that are complementary to our own and other general corporate expenses.

We may experience difficulties in integrating Herley's business and realizing the expected benefits of the proposed Merger.

Our ability to achieve the benefits we anticipate from the proposed Merger will depend in large part upon whether we are able to integrate Herley's business into our business in an efficient and effective manner. Because the businesses of Herley and Kratos differ, we may not be able to integrate Herley's business smoothly or successfully and the process may take longer than expected. The integration of certain operations, including Herley's international operations, and the differences in operational culture following the Merger will require the dedication of significant management resources, which may distract management's attention from day-to-day business operations. If we are unable to successfully integrate the operations of Herley's business into our business, we may be unable to realize the revenue growth, synergies

and other anticipated benefits we expect to achieve as a result of the proposed Merger and our business and results of operations could be adversely affected.

The announcement and pendency of the proposed Merger may cause disruptions in Herley's business, which could have an adverse effect on our business, financial condition or results of operations following completion of the Merger.

The announcement and pendency of the proposed Merger could cause disruptions in the business of Herley. Specifically:

•

current and prospective employees of Herley may experience uncertainty about their future roles with Kratos, which might adversely affect the ability of Herley to retain key personnel and attract new personnel;

•

current and prospective customers of Herley may experience uncertainty about the ability of Herley to meet their needs, which might cause customers to seek other suppliers for the products and services provided by Herley; and

•

management's attention may be focused on the Merger, which may divert management's attention from the core business of Herley and other opportunities that could have been beneficial to Herley.

This could have an adverse effect on the business, financial condition or results of operations of Herley prior to the completion of the Merger and on us following the completion of the Merger. These disruptions to Herley's business could be exacerbated by a delay in the completion of the Merger.

The historical and unaudited pro forma financial information included elsewhere in this prospectus supplement may not be representative of our results as a combined company after the Merger, and accordingly, you have limited financial information on which to evaluate the combined company and your investment decision.

We and Herley have no prior history as a combined entity and our operations have not previously been managed on a combined basis. The pro forma financial information, which was prepared in accordance with Article 11 of the SEC's Regulation S-X, is presented for informational purposes only and is not necessarily indicative of the financial position or results of operations that would have actually occurred had the Merger been completed at or as of the dates indicated, nor is it indicative of the future operating results or financial position of the combined company. The pro forma financial information does not reflect future nonrecurring charges resulting from the Merger. The Unaudited Pro Forma Condensed Combined Financial Data does not reflect future events that may occur after the Merger, including the potential realization of operating cost savings (synergies) or restructuring activities or other costs related to the planned integration of Herley, and does not consider potential impacts of current market conditions on revenues, expense efficiencies or asset dispositions. The pro forma financial information presented in this prospectus supplement is based in part on certain assumptions regarding the Merger that we believe are reasonable under the circumstances. We cannot assure you that our assumptions will prove to be accurate over time.

Herley may have liabilities that are not known, probable or estimable at this time.

As a result of the Merger, Herley will become our subsidiary and we will effectively assume all of its liabilities, whether or not asserted. There could be unasserted claims or assessments that we failed or were unable to discover or identify in the course of performing due diligence investigations of Herley. In addition, there may be liabilities that are neither probable nor estimable at this time which may become probable and estimable in the future. Any such liabilities, individually or in the aggregate, could have a material adverse effect on our business. We may learn additional information about Herley that adversely affects us, such as unknown, unasserted or contingent liabilities and issues relating to compliance with applicable laws.

The Merger may not be accretive and may cause dilution to the combined company's earnings per share, which may negatively impact the price of the common stock of the combined company following the completion of the Merger.

We currently anticipate that the Merger will be accretive to the earnings per share ("EPS") of the combined company during the first full calendar year after the Merger is completed. This expectation is based on preliminary estimates and estimated purchase price valuations of amortizable purchased intangibles and assumes certain synergies expected to be realized by the combined company during such time, including the elimination of Herley's expenses related to operating as a publicly traded company. Such estimates and assumptions could materially change due to additional transaction-related costs, any changes in the final purchase price valuation of amortizable purchased intangibles, the failure to realize any or all of the benefits expected in the Merger or other factors beyond our control or the control of Herley. All of these factors could delay, decrease or eliminate the expected accretive effect of the Merger and cause resulting dilution to the combined company's EPS or to the price of the common stock of the combined company.

Risks Related to Our Business Currently and Following the Proposed Acquisition of Herley

Our business could be adversely affected by changes in the contracting or fiscal policies of the U.S. federal government and governmental entities.

We derive a significant portion of our revenue from contracts with the U.S. federal government and government agencies and subcontracts under federal government prime contracts, and the success of our business and growth of our business will continue to depend on our successful procurement of government contracts either directly or through prime contractors. Current projections of the DoD indicate that government spending is expected to decrease beginning in 2011. Any such reductions or other government budgetary constraints and any changes in government contracting policies could directly affect our financial performance. Among the factors that could adversely affect our business are:

•

changes in fiscal policies or decreases in available government funding, including budgetary constraints affecting federal government spending generally, or specific departments or agencies in particular;

•

the adoption of new laws or regulations or changes to existing laws or regulations;

•

changes in political or social attitudes with respect to security and defense issues;

•

changes in federal government programs or requirements, including the increased use of small business providers;

•

increases in the federal government initiatives related to in-sourcing;

•

changes in or delays related to government restrictions on the export of defense articles and services;

•

potential delays or changes in the government appropriations process; and

•

delays in the payment of our invoices by government payment offices.

These and other factors could cause governments and government agencies, or prime contractors that use us as a subcontractor, to reduce their purchases under existing contracts, to exercise their rights to terminate contracts at-will or to abstain from exercising options to renew contracts, any of which could have an adverse effect on our business, financial condition and results of operations. Many of our government customers are subject to stringent budgetary constraints. The award of additional contracts from government agencies could be adversely affected by spending reductions or budget cutbacks at these agencies.

Our credit facility contains restrictive covenants that could limit our ability to operate our business and, if not satisfied, could result in the acceleration of any amounts then due under the credit facility.

The agreement governing our credit facility subjects us to various financial and other covenants with which we must comply. These covenants require that we maintain a minimum fixed charge coverage ratio and include restrictions on our ability to:

•

incur additional debt;

•

create or incur liens;

•

bid on or perform work due to limits on the amount of performance bonds that may be secured by letters of credit;

•

pay dividends or make other equity distributions to our stockholders;

•

make investments and effect certain acquisitions;

•

sell assets;

•

issue or become liable on a guarantee;

•

create or acquire new subsidiaries; and

•

effect a merger or consolidation, or sell all or substantially all of our assets.

Upon the occurrence of any event of default under our credit facility, our lenders could elect to declare all amounts then outstanding on our credit facility, together with accrued interest, to be immediately due and payable. If our lenders were to accelerate payment of these amounts, we may not have sufficient assets to repay them in full. In addition, if we fail to comply with these financial and other covenants, or are otherwise unable to make scheduled debt payments or comply with the other provisions of our debt instruments, our lenders may be permitted under certain circumstances to deny future access to liquidity, seize control of substantially all of our assets and exercise other remedies provided for in those agreements and under applicable law.

We may need additional capital to fund the growth of our business, and financing may not be available on favorable terms or at all.

We currently anticipate that our available capital resources, including our credit facility and operating cash flow, will be sufficient to meet our expected working capital and capital expenditure requirements for at least the next 12 months. However, such resources may not be sufficient to fund the long-term growth of our business. If we determine that it is necessary to raise additional funds, either through an expansion or refinancing of our credit facility or through public or private debt or equity financings, additional financing may not be available on terms favorable to us, or at all. Disruptions in the capital and credit markets may continue indefinitely or intensify, which could adversely affect our ability to access these markets. Limitations on our borrowing base contained in our credit facility may limit our access to capital, and we could fall out of compliance with financial and other covenants contained in our credit facility which, if not waived, would restrict our access to capital and could require us to pay down our existing debt under the credit facility. Our lenders may not agree to extend additional or continuing credit under our credit facility or waive restrictions on our access to capital. If we were to conduct a public or private offering of securities, any new offering would be likely to dilute our stockholders' equity ownership. If adequate funds are not available or are not available on acceptable terms, we may not be able to take advantage of available opportunities, develop new products or otherwise respond to competitive pressures and our business, operating results or financial condition could be materially adversely affected.

Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited.

Federal and state income tax laws impose restrictions on the utilization of net operating loss ("NOL") and tax credit carryforwards in the event that an "ownership change" occurs for tax purposes, as defined by Section 382 of the Internal Revenue Code of 1986, as amended. In general, an ownership change occurs when shareholders owning 5% or more of a "loss corporation" (a corporation entitled to use NOL or other loss carryovers) have increased their ownership of stock in such corporation by more than 50 percentage points during any 3-year period. The annual base Section 382 limitation is calculated by multiplying the loss corporation's value at the time of the ownership change by the greater of the long-term tax-exempt rate determined by the Internal Revenue Service in the month of the ownership change or the two preceding months. In March 2010 an "ownership change" occurred which will limit the utilization of the loss carryforwards. As a result, our annual utilization of NOL carryforwards will be limited to $28.1 million for five years and $11.6 million per year thereafter. For the quarter ended September 26, 2010, there was no impact of such limitations on the income tax provision since the amount of taxable income did not exceed the annual limitation amount. In addition, future equity offerings or acquisitions that have equity as a component of the purchase price could also result in an "ownership change". If and when any other "ownership change" occurs, utilization of the NOL or other tax attributes may be further limited.

We derive a substantial amount of our revenues from the sale of our solutions either directly or indirectly to U.S. government entities pursuant to government contracts, which differ materially from standard commercial contracts, involve competitive bidding and may be subject to cancellation or delay without penalty, any of which may produce volatility in our revenues and earnings.

Government contracts frequently include provisions that are not standard in private commercial transactions, and are subject to laws and regulations that give the federal government rights and remedies not typically found in commercial contracts, including provisions permitting the federal government to:

•

terminate our existing contracts;

•

reduce potential future income from our existing contracts;

•

modify some of the terms and conditions in our existing contracts;

•

suspend or permanently prohibit us from doing business with the federal government or with any specific government agency;

•

impose fines and penalties;

•

subject us to criminal prosecution;

•

suspend work under existing multiple year contracts and related task orders if the necessary funds are not appropriated by Congress;

•

decline to exercise an option to extend an existing multiple year contract; and

•

claim rights in technologies and systems invented, developed or produced by us.

In addition, government contracts are frequently awarded only after formal competitive bidding processes, which have been and may continue to be protracted and typically impose provisions that permit cancellation in the event that necessary funds are unavailable to the public agency. Competitive procurements impose substantial costs and managerial time and effort in order to prepare bids and proposals for contracts that may not be awarded to us. In many cases, unsuccessful bidders for government agency contracts are provided the opportunity to formally protest certain contract awards through various agencies, administrative and judicial channels. The protest process may substantially delay a successful bidder's contract performance, result in cancellation of the contract award entirely and distract management. We may not be awarded contracts for which we bid, and substantial delays or cancellation of purchases may follow our successful bids as a result of such protests.

S-22

Certain of our government contracts also contain "organizational conflict of interest" clauses that could limit our ability to compete for certain related follow-on contracts. For example, when we work on the design of a particular solution, we may be precluded from competing for the contract to install that solution. While we actively monitor our contracts to avoid these conflicts, we cannot guarantee that we will be able to avoid all organizational conflict of interest issues.

We may not receive the full amounts estimated under the contracts in our backlog, which could reduce our revenue in future periods below the levels anticipated and which makes backlog an uncertain indicator of future operating results.

As of September 26, 2010, our backlog was approximately $660 million, of which $285 was funded. On a pro forma basis, as of such date, our backlog was approximately $883 million, of which $508 million was funded. Funded backlog is estimated future revenue under government contracts and task orders for which funding has been appropriated by Congress and authorized for expenditure by the applicable agency, plus our estimate of the future revenue we expect to realize from our commercial contracts that are under firm orders. Although funded backlog represents only business which is considered to be firm, cancellations or scope adjustments may still occur. The remaining $375 million of our total backlog as of September 26, 2010 is unfunded. Unfunded backlog reflects our estimate of future revenue under awarded government contracts and task orders for which either funding has not yet been appropriated or expenditure has not yet been authorized. Unfunded backlog does not include estimates of revenue from government wide acquisition contracts ("GWAC") or General Services Administration ("GSA") schedules beyond awarded or funded task orders, but does include estimates of revenue beyond awarded or funded task orders for other types of indefinite quantity contracts. The amount of unfunded backlog is not exact or guaranteed and is based upon, among other things, management's experience under such contracts and similar contracts, the particular clients, the type of work and budgetary expectations. Our management may not accurately assess these factors or estimate the revenue we will realize from these contracts, and our unfunded and total backlog may not reflect the actual revenue ultimately received from these contracts.

Backlog is typically subject to large variations from quarter to quarter and comparisons of backlog from period to period are not necessarily indicative of future revenues. The contracts comprising our backlog may not result in actual revenue in any particular period or at all, and the actual revenue from such contracts may differ from our backlog estimates. The timing of receipt of revenues, if any, on projects included in backlog could change because many factors affect the scheduling of projects. Cancellation of or adjustments to contracts may occur. Additionally, all U.S. government contracts included in backlog, whether or not funded, may be terminated at the convenience of the U.S. government. The failure to realize all amounts in our backlog could adversely affect our revenues and gross margins. As a result, our funded and total backlog as of any particular date may not be an accurate indicator of our future earnings.

We face intense competition from many competitors that have greater resources than we do, which could result in price reductions, reduced profitability or loss of market share.

We operate in highly competitive markets and generally encounter intense competition to win contracts from many other firms, including mid-tier federal contractors with specialized capabilities and large defense and IT services providers. Competition in our markets may increase as a result of a number of factors, such as the entrance of new or larger competitors, including those formed through alliances or consolidation. These competitors may have greater financial, technical, marketing and public relations resources, larger client bases and greater brand or name recognition than we do. These competitors could, among other things:

•

divert sales from us by winning very large-scale government contracts, a risk that is enhanced by the recent trend in government procurement practices to bundle services into larger contracts;

•

force us to charge lower prices; or

•

adversely affect our relationships with current clients, including our ability to continue to win competitively awarded engagements in which we are the incumbent.

S-23

Table of Contents

If we lose business to our competitors or are forced to lower our prices, our revenue and our operating profits could decline. In addition, we may face competition from our subcontractors who, from time-to-time, seek to obtain prime contractor status on contracts for which they currently serve as a subcontractor to us. If one or more of our current subcontractors are awarded prime contractor status on such contracts in the future, it could divert sales from us or could force us to charge lower prices, which could cause our margins to suffer.

Recent acquisitions and potential future acquisitions could prove difficult to integrate, disrupt our business, dilute stockholder value and strain our resources.

On May 19, 2010, we acquired 100% of the voting equity interests of Gichner headquartered in Dallastown, Pennsylvania, pursuant to the Stock Purchase Agreement, dated as of April 12, 2010, by and between the Kratos and the stockholders of Gichner. On November 15, 2010, we acquired HBE pursuant to an Agreement and Plan of Merger, dated October 5, 2010, by and among Kratos, Hammer Acquisition Inc., a Delaware corporation and a wholly-owned subsidiary of Kratos ("Hammer Merger Sub"), and HBE, whereby Hammer Merger Sub merged with and into HBE, and HBE continued as the surviving corporation and as our wholly-owned subsidiary.

We continually evaluate opportunities to acquire new businesses as part of our ongoing strategy and we may in the future acquire additional businesses that we believe could complement or expand our business or increase our customer base. Integrating the operations of acquired businesses successfully or otherwise realizing any of the anticipated benefits of acquisitions, including anticipated cost savings and additional revenue opportunities, involves a number of potential challenges. The failure to meet these integration challenges could seriously harm our financial condition and results of operations. Realizing the benefits of acquisitions depends in part on the integration of information technology ("IT") operations and personnel. These integration activities are complex and time-consuming and we may encounter unexpected difficulties or incur unexpected costs, including:

•

our inability to achieve the operating synergies anticipated in the acquisitions;

•

diversion of management attention from ongoing business concerns to integration matters;

•

difficulties in consolidating and rationalizing IT platforms and administrative infrastructures;

•

complexities associated with managing the geographic separation of the combined businesses and consolidating multiple physical locations where management may determine consolidation is desirable;

•

difficulties in integrating personnel from different corporate cultures while maintaining focus on providing consistent, high quality customer service;

•

difficulties or delays in transitioning federal government contracts pursuant to federal acquisition regulations;

•

challenges in demonstrating to customers of Kratos and to customers of the acquired businesses that the acquisition will not result in adverse changes in customer service standards or business focus;

•

possible cash flow interruption or loss of revenue as a result of change of ownership transitional matters; and

•

inability to generate sufficient revenue to offset acquisition costs.

Acquired businesses may have liabilities or adverse operating issues that we fail to discover through due diligence prior to the acquisition. In particular, to the extent that prior owners of any acquired businesses or properties failed to comply with or otherwise violated applicable laws or regulations, or failed to fulfill their contractual obligations to the federal government or other clients, we, as the successor owner, may be financially responsible for these violations and failures and may suffer reputational harm or otherwise be adversely affected. Acquisitions also frequently result in the recording of goodwill and other intangible assets which are subject to potential impairment in the future that could harm our financial results. In addition, if we finance acquisitions by issuing convertible debt or equity securities, our existing stockholders

S-24

Table of Contents

may be diluted, which could affect the market price of our stock. Acquisitions and/or the related equity financings could also impact our ability to utilize our NOL carryforwards. As a result, if we fail to properly evaluate acquisitions or investments, we may not achieve the anticipated benefits of any such acquisitions, and we may incur costs in excess of what we anticipate. Acquisitions frequently involve benefits related to integration of operations. The failure to successfully integrate the operations or otherwise to realize any of the anticipated benefits of the acquisition could seriously harm our results of operations.

If we are unable to manage our growth, our business and financial results could suffer.

Sustaining our growth has placed significant demands on our management, as well as on our administrative, operational and financial resources. For us to continue to manage our growth, we must continue to improve our operational, financial and management information systems and expand, motivate and manage our workforce. If we are unable to manage our growth while maintaining our quality of service and profit margins, or if new systems that we implement to assist in managing our growth do not produce the expected benefits, our business, prospects, financial condition or operating results could be adversely affected.

Additionally, our future financial results depend in part on our ability to profitably manage our growth on a combined basis with the businesses we acquire. Management will need to maintain existing customers and attract new customers, recruit, retain and effectively manage employees, as well as expand operations and integrate customer support and financial control systems. If the integration-related expenses and capital expenditure requirements are greater than anticipated or if we are unable to manage our growth profitably after business acquisitions, our financial condition and results of operations may suffer.

Our financial results may vary significantly from quarter to quarter.

We expect our revenue and operating results to vary from quarter to quarter. Reductions in revenue in a particular quarter could lead to lower profitability in that quarter because a relatively large amount of our expenses are fixed in the short-term. We may incur significant operating expenses during the start-up and early stages of large contracts and may not be able to recognize corresponding revenue in that same quarter. We may also incur additional expenses when contracts are terminated or expire and are not renewed.

In addition, payments due to us from federal government agencies may be delayed due to billing cycles or as a result of failures of government budgets to gain congressional and administration approval in a timely manner. The U.S. federal government's fiscal year ends September 30. If a federal budget for the next federal fiscal year has not been approved by that date in each year, our clients may have to suspend engagements that we are working on until a budget has been approved. Any such suspensions may reduce our revenue in the fourth quarter of the federal fiscal year or the first quarter of the subsequent federal fiscal year. The U.S. federal government's fiscal year end can also trigger increased purchase requests from clients for equipment and materials. Any increased purchase requests we receive as a result of the U.S. federal government's fiscal year end would serve to increase our third or fourth quarter revenue, but will generally decrease profit margins for that quarter, as these activities generally are not as profitable as our typical offerings.

Additional factors that may cause our financial results to fluctuate from quarter to quarter include those addressed elsewhere in these Risk Factors and the following, among others:

•

the terms of customer contracts that affect the timing of revenue recognition;

•

variability in demand for our services and solutions;

•

commencement, completion or termination of contracts during any particular quarter;

•

timing of award or performance incentive fee notices;

•

timing of significant bid and proposal costs;

Significant fluctuations in our operating results for a particular quarter could cause us to fall out of compliance with the financial covenants contained in our credit facility, which if not waived by the lender, could restrict our access to capital and cause us to take extreme measures to pay down our debt under the credit facility. In addition, fluctuations in our financial results could cause our stock price to decline.

If we fail to establish and maintain important relationships with government entities and agencies and other government contractors, our ability to bid successfully for new business may be adversely affected.

To develop new business opportunities, we primarily rely on establishing and maintaining relationships with various government entities and agencies. We may be unable to successfully maintain our relationships with government entities and agencies, and any failure to do so could materially adversely affect our ability to compete successfully for new business. In addition, we often act as a subcontractor or in "teaming" arrangements in which we and other contractors bid together on particular contracts or programs for the federal government or government agencies. As a subcontractor or team member, we often lack control over fulfillment of a contract, and poor performance on the contract could tarnish our reputation, even when we perform as required. We expect to continue to depend on relationships with other contractors for a portion of our revenue in the foreseeable future. Moreover, our revenue and operating results could be materially adversely affected if any prime contractor or teammate chooses to offer a client services of the type that we provide or if any prime contractor or teammate teams with other companies to independently provide those services.

Our margins and operating results may suffer if we experience unfavorable changes in the proportion of cost-plus-fee or fixed-price contracts in our total contract mix.

Although fixed-price contracts entail a greater risk of a reduced profit or financial loss on a contract compared to other types of contracts we enter into, fixed-price contracts typically provide higher profit opportunities because we may be able to benefit from cost savings. In contrast, cost-plus-fee contracts are subject to statutory limits on profit margins, and generally are the least profitable of our contract types. Our federal government customers typically determine what type of contract we enter into. Cost-plus-fee and fixed-price contracts in our federal business accounted for approximately 24% and 57%, respectively, of our federal business revenues for the three months ended September 26, 2010 and approximately 28% and 47%, respectively, of our federal business revenues for the nine months ended September 26, 2010. To the extent that we enter into more cost-plus-fee or less fixed-price contracts in proportion to our total contract mix in the future, our margins and operating results may suffer.

Our cash flow and profitability could be reduced if expenditures are incurred prior to the final receipt of a contract.

We provide various professional services and sometimes procure equipment and materials on behalf of our federal government customers under various contractual arrangements. From time to time, in order to ensure that we satisfy our customers' delivery requirements and schedules, we may elect to initiate procurement in advance of receiving final authorization from the government customer or a prime contractor. If our government or prime contractor customers' requirements should change or if the government or the prime contractor should direct the anticipated procurement to a contractor other than us or if the equipment or materials become obsolete or require modification before we are under contract for the procurement, our investment in the equipment or materials might be at risk if we cannot efficiently resell them. This could reduce anticipated earnings or result in a loss, negatively affecting our cash flow and profitability.

Loss of our GSA contracts or GWACs would impair our ability to attract new business.

We are a prime contractor under several GSA contracts and GWAC vehicles. We believe that our ability to provide services under these contracts will continue to be important to our business because of the multiple opportunities for new engagements that each contract provides. If we were to lose our position as prime contractor on one or more of these contracts, we could lose substantial revenues and our operating results could suffer. GSA contracts and other GWACs typically have a one or two-year initial term with multiple options exercisable at the government client's discretion to extend the contract for one or more years. We cannot be assured that our government clients will continue to exercise the options remaining on our current contracts, nor can we be assured that our future clients will exercise options on any contracts we may receive in the future.

Failure to properly manage projects may result in additional costs or claims.

Our engagements often involve large-scale, highly complex projects. The quality of our performance on such projects depends in large part upon our ability to manage the relationship with our customers, and to effectively manage the project and deploy appropriate resources, including third-party contractors, and our own personnel, in a timely manner. Any defects or errors or failure to meet clients' expectations could result in claims for substantial damages against us. Our contracts generally limit our liability for damages that arise from negligent acts, error, mistakes or omissions in rendering services to our clients. However, we cannot be sure that these contractual provisions will protect us from liability for damages in the event we are sued. In addition, in certain instances, we guarantee customers that we will complete a project by a scheduled date. If the project experiences a performance problem, we may not be able to recover the additional costs we will incur, which could exceed revenues realized from a project. Finally, if we underestimate the resources or time we need to complete a project with capped or fixed fees, our operating results could be seriously harmed.

The loss of any member of our senior management could impair our relationships with federal government clients and disrupt the management of our business.

We believe that the success of our business and our ability to operate profitably depends on the continued contributions of the members of our senior management. We rely on our senior management to generate business and execute programs successfully. In addition, the relationships and reputation that many members of our senior management team have established and maintain with federal government personnel contribute to our ability to maintain strong client relationships and to identify new business opportunities. We do not have any employment agreements providing for a specific term of employment with any member of our senior management. The loss of any member of our senior management could impair our ability to identify and secure new contracts, maintain good client relations and otherwise manage our business.

If we fail to attract and retain skilled employees or employees with the necessary security clearances, we might not be able to perform under our contracts or win new business.

The growth of our business and revenue depends in large part upon our ability to attract and retain sufficient numbers of highly qualified individuals who have advanced information technology and/or engineering skills. These employees are in great demand and are likely to remain a limited resource in the foreseeable future. Certain federal government contracts require us, and some of our employees, to maintain security clearances. Obtaining and maintaining security clearances for employees involves a lengthy process, and it is difficult to identify, recruit and retain employees who already hold security clearances. In addition, some of our contracts contain provisions requiring us to staff an engagement with personnel that the client considers key to our successful performance under the contract. In the event we are unable to provide these key personnel or acceptable substitutions, the client may terminate the contract and we may lose revenue.

If we are unable to recruit and retain a sufficient number of qualified employees, our ability to maintain and grow our business could be limited. In a tight labor market, our direct labor costs could increase or we may be required to engage large numbers of subcontractor personnel, which could cause our profit margins to suffer. Conversely, if we maintain or increase our staffing levels in anticipation of one or more projects and the projects are delayed, reduced or terminated, we may underutilize the additional personnel, which would increase our general and administrative expenses, reduce our earnings and possibly harm our results of operations.

If our subcontractors fail to perform their contractual obligations, our performance and reputation as a prime contractor and our ability to obtain future business could suffer.

As a prime contractor, we often rely upon other companies as subcontractors to perform work we are obligated to perform for our clients. As we secure more work under our GWAC vehicles, we expect to require an increasing level of support from subcontractors that provide complementary and supplementary services to our offerings. Depending on labor market conditions, we may not be able to identify, hire and retain sufficient numbers of qualified employees to perform the task orders we expect to win. In such cases, we will need to rely on subcontracts with unrelated companies. Moreover, even in favorable labor market conditions, we anticipate entering into more subcontracts in the future as we expand our work under our GWACs. We are responsible for the work performed by our subcontractors, even though in some cases we have limited involvement in that work.

If one or more of our subcontractors fail to satisfactorily perform the agreed-upon services on a timely basis or violate federal government contracting policies, laws or regulations, our ability to perform our obligations as a prime contractor or meet our clients' expectations may be compromised. In extreme cases, performance or other deficiencies on the part of our subcontractors could result in a client terminating our contract for default. A termination for default could expose us to liability, including liability for the agency's costs of procurement, could damage our reputation and could hurt our ability to compete for future contracts.

Our contracts and administrative processes and systems are subject to audits and cost adjustments by the federal government, which could reduce our revenue, disrupt our business or otherwise adversely affect our results of operations.

Federal government agencies, including the Defense Contract Audit Agency ("DCAA"), routinely audit and investigate government contracts and government contractors' administrative processes and systems. These agencies review our performance on contracts, pricing practices, cost structure and compliance with applicable laws, regulations and standards. They also review the adequacy of our compliance with government standards for its accounting and management of internal control systems, including: control environment and overall accounting system, general information technology system, budget and planning system, purchasing system, material management and accounting system, compensation system, labor

S-28

Table of Contents

system, indirect and other direct costs system, billing system and estimating system used for pricing on government contracts. Both contractors and the U.S. government agencies conducting these audits and reviews have come under increased scrutiny. The current audits and reviews have become more rigorous and the standards to which contractors are being held are being more strictly interpreted, increasing the likelihood of an audit or review resulting in an adverse outcome.

While we have submitted all applicable incurred cost claims, the actual indirect cost audits by the DCAA have not been completed for fiscal 2005 and subsequent fiscal years. Although we have recorded contract revenues subsequent to fiscal 2004 based upon costs that we believe will be approved upon final audit or review, we do not know the outcome of any ongoing or future audits or reviews and, if future adjustments exceed our estimates, our profitability would be adversely affected.

Our failure to comply with complex procurement laws and regulations could cause us to lose business and subject us to a variety of penalties.

We must comply with laws and regulations relating to the formation, administration and performance of federal government contracts, which affect how we do business with our clients, prime contractors, subcontractors and vendors and may impose added costs on us. Our role as a contractor to agencies and departments of the U.S. government results in our being routinely subject to investigations and reviews relating to compliance with various laws and regulations, including those associated with organizational conflicts of interest. These investigations may be conducted without our knowledge. Adverse findings in these investigations or reviews can lead to criminal, civil or administrative proceedings and we could face civil and criminal penalties and administrative sanctions, including termination of contracts, forfeiture of profits, suspension of payments, fines and suspension or debarment from doing business with federal government agencies. In addition, we could suffer serious harm to our reputation and competitive position if allegations of impropriety were made against us, whether or not true. If our reputation or relationship with federal government agencies were impaired, or if the federal government otherwise ceased doing business with us or significantly decreased the amount of business it does with us, our revenue and operating profit would decline.

If we experience systems or service failure, our reputation could be harmed and our clients could assert claims against us for damages or refunds.

We create, implement and maintain IT solutions that are often critical to our clients' operations. We have experienced, and may in the future experience, some systems and service failures, schedule or delivery delays and other problems in connection with our work. If we experience these problems, we may:

•

lose revenue due to adverse client reaction;

•

be required to provide additional services to a client at no charge;

•

receive negative publicity, which could damage our reputation and adversely affect our ability to attract or retain clients; and

•

suffer claims for substantial damages.

In addition to any costs resulting from product or service warranties, contract performance or required corrective action, these failures may result in increased costs or loss of revenue if clients postpone subsequently scheduled work or cancel, or fail to renew, contracts.

While many of our contracts limit our liability for consequential damages that may arise from negligence in rendering services to our clients, we cannot ensure that these contractual provisions will be legally sufficient to protect us if we are sued. In addition, our errors and omissions and product liability insurance coverage may not be adequate, may not continue to be available on reasonable terms or in sufficient amounts to cover one or more large claims, or the insurer may disclaim coverage as to some types of future claims. The successful assertion of any large claim against us could seriously harm our business. Even if not successful, these claims could result in significant legal and other costs, may be a distraction to our management and may harm our reputation.

Security breaches in sensitive federal government systems could result in the loss of clients and negative publicity.

Many of the systems we develop, install and maintain involve managing and protecting information involved in intelligence, national security and other sensitive or classified federal government functions. A security breach in one of these systems could cause serious harm to our business, damage our reputation and prevent us from being eligible for further work on sensitive or classified systems for federal government clients. We could incur losses from such a security breach that could exceed the policy limits under our errors and omissions and product liability insurance. Damage to our reputation or limitations on our eligibility for additional work resulting from a security breach in one of the systems we develop, install and maintain could materially reduce our revenue.

Our employees may engage in misconduct or other improper activities, which could cause us to lose contracts.

We are exposed to the risk that employee fraud or other misconduct could occur. Misconduct by employees could include intentional failures to comply with federal government procurement regulations, engaging in unauthorized activities or falsifying time records. Employee misconduct could also involve the improper use of our clients' sensitive or classified information, which could result in regulatory sanctions against us and serious harm to our reputation and could result in a loss of contracts and a reduction in revenues. It is not always possible to deter employee misconduct, and the precautions we take to prevent and detect this activity may not be effective in controlling unknown or unmanaged risks or losses, which could cause us to lose contracts or cause a reduction in revenues. In addition, alleged or actual employee misconduct could result in investigations or prosecutions of employees engaged in the subject activities, which could result in unanticipated consequences or expenses and management distraction for us regardless of whether we are alleged to have any responsibility.

Our business is dependent upon our ability to keep pace with the latest technological changes.

The market for our services is characterized by rapid change and technological improvements. Failure to respond in a timely and cost-effective way to these technological developments would result in serious harm to our business and operating results. We have derived, and we expect to continue to derive, a substantial portion of our revenues from providing innovative engineering services and technical solutions that are based upon today's leading technologies and that are capable of adapting to future technologies. As a result, our success will depend, in part, on our ability to develop and market service offerings that respond in a timely manner to the technological advances of our customers, evolving industry standards and changing client preferences.

We may be harmed by intellectual property infringement claims and our failure to protect our intellectual property could enable competitors to market products and services with similar features.

We may become subject to claims from our employees or third parties who assert that software and other forms of intellectual property that we use in delivering services and solutions to our clients infringe upon intellectual property rights of such employees or third parties. Our employees develop some of the software and other forms of intellectual property that we use to provide our services and solutions to our clients, but we also license technology from other vendors. If our employees, vendors, or other third parties assert claims that we or our clients are infringing on their intellectual property rights, we could incur substantial costs to defend those claims. If any of these infringement claims are ultimately successful, we could be required to cease selling or using products or services that incorporate the challenged software or technology, obtain a license or additional licenses from our employees, vendors, or other third parties, or redesign our products and services that rely on the challenged software or technology.

We attempt to protect our trade secrets by entering into confidentiality and intellectual property assignment agreements with third parties, our employees and consultants. However, these agreements can be breached and, if they are, there may not be an adequate remedy available to us. In addition, others may independently discover our trade secrets and proprietary information and in such cases we could not assert any trade secret rights against such party. Enforcing a claim that a party illegally obtained and is using our trade secret is difficult, expensive and time consuming, and the outcome is unpredictable. If we are unable to protect our intellectual property, our competitors could market services or products similar to our services and products, which could reduce demand for our offerings. Any litigation to enforce our intellectual property rights, protect our trade secrets or determine the validity and scope of the proprietary rights of others could result in substantial costs and diversion of resources, with no assurance of success.

If we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial results or prevent fraud.

Effective internal controls are necessary for us to provide reliable financial reports. If we cannot provide reliable financial reports, our operating results could be misstated, our reputation may be harmed and the trading price of our stock could be negatively affected. Our management has concluded that there are no material weaknesses in our internal controls over financial reporting as of December 27, 2009. However, there can be no assurance that our controls over financial processes and reporting will be effective in the future or that additional material weaknesses or significant deficiencies in our internal controls will not be discovered in the future. Any failure to remediate any future material weaknesses or implement required new or improved controls, or difficulties encountered in their implementation, could harm our operating results, cause us to fail to meet our reporting obligations or result in material misstatements in our financial statements or other public disclosures. Inferior internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our stock. In addition, from time to time we acquire businesses which could have limited infrastructure and systems of internal controls.

We have incurred and may continue to incur goodwill impairment charges in our reporting entities which could harm our profitability.

A significant portion of our net assets come from goodwill and other intangible assets. In accordance with Financial Accounting Standards Board Accounting Standards Code Topic 350 Intangibles — Goodwill and Other ("Topic 350") we periodically review the carrying values of our goodwill to determine whether such carrying values exceed the fair market value. Our acquired companies are subject to annual review for goodwill impairment. If impairment testing indicates that the carrying value of a reporting unit exceeds its fair value, the goodwill of the reporting unit is deemed impaired. Accordingly, an impairment charge would be recognized for that reporting unit in the period identified.

In 2008, as a result of our annual review, we recorded a goodwill impairment charge of $105.8 million related to our Kratos Government Solutions ("KGS") segment, to reflect the declining market and economic conditions through December 28, 2008. In the beginning of 2009, we performed another impairment test for goodwill in accordance with Topic 350 as of February 28, 2009. The test indicated that the book value for the KGS segment exceeded the fair values of the businesses and resulted in our recording a charge totaling $41.3 million in that segment for the impairment of goodwill. The impairment charge was primarily driven by adverse equity market conditions that caused a decrease in current market multiples and our average stock price as of February 28, 2009, compared with the test performed as of December 28, 2008. Future reviews could result in further impairment charges, which could have a significant effect on our financial results.

The commercial business arena in which we operate has relatively low barriers to entry and increased competition could result in margin erosion, which would make profitability even more difficult to sustain.

Other than the technical skills required in our commercial business, the barriers to entry in this area are relatively low. We do not have any intellectual property rights in this segment of our business to protect our methods, and business start-up costs do not pose a significant barrier to entry. The success of our commercial business is dependent upon our employees, customer relations and the successful performance of our services. If we face increased competition as a result of new entrants in our markets, we could experience reduced operating margins and loss of market share and brand recognition.

We significantly increased our leverage in connection with the financing of recent acquisitions.

We incurred approximately $225.0 million of indebtedness in the form of 10% Senior Secured Notes (the "Original Notes") in connection with our financing of our acquisition of Gichner. On August 11, 2010, we completed an exchange offer for the Original Notes pursuant to a registration rights agreement entered into in connection with the issuance of the Original Notes (such exchanged notes referred to elsewhere in this prospectus supplement as the "Existing Notes"). As a result of this indebtedness, our interest payment obligations have increased. The degree to which we are leveraged could have adverse effects on our business, including the following:

•

it may make it difficult for us to satisfy our obligations under the Existing Notes, and our other indebtedness and contractual and commercial commitments;

•

it may require us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, thereby reducing the availability of our cash flow to fund working capital, capital expenditures and other general corporate purposes;

•

it may limit our flexibility in planning for, or reacting to, changes in our business and the industries in which we operate;

•

it may restrict us from making strategic acquisitions or exploiting business opportunities;

•

it may place us at a competitive disadvantage compared to our competitors that have less debt;

•

it may limit our ability to borrow additional funds;

•

it may prevent us from raising the funds necessary to repurchase the Existing Notes tendered to us if there is a change of control, which would constitute a default under the indentures governing the Existing Notes and under our credit facility; and

•

it may decrease our ability to compete effectively or operate successfully under adverse economic and industry conditions.

If new debt is incurred, these risks may intensify. Our ability to meet our debt service obligations will depend upon our future performance, which may be subject to the financial, business and other factors affecting our operations, many of which are beyond our control.

Any increase in our debt service obligations, including in connection with our proposed acquisition of Herley, may adversely affect our cash flow.

We expect our cash requirements in connection with our proposed acquisition of Herley to be approximately $318 million. On a pro forma basis, after giving effect to our acquisition of HBE on December 15, 2010 and our proposed acquisition of Herley, we would have had total long-term debt of $480.1 million as of September 26, 2010, assuming that we raise $40 million in this offering and $265 million of new indebtedness to fund the proposed acquisition of Herley. We currently intend to raise approximately $325 million through debt financing in order to fund the proposed acquisition of Herley, with any excess used for other general corporate purposes (although any such additional amount is not reflected in the pro forma financial data included elsewhere in this prospectus). A higher level of indebtedness increases the risk that we may default on our debt obligations. We may not be able to generate sufficient cash flow to pay the interest on our debt, and future working capital, borrowings or equity financing may not be available to

S-32

Table of Contents

pay or refinance such debt. If we are unable to generate sufficient cash flow to pay the interest on our debt, we may have to delay or curtail our operations.

Our ability to generate cash flow from operations and to make scheduled payments on our indebtedness will depend on our future financial performance. Our future financial performance will be affected by a range of economic, competitive and business factors that we cannot control. A significant reduction in operating cash flow resulting from changes in economic conditions, increased competition or other events beyond our control could increase the need for additional or alternative sources of liquidity and could have a material adverse effect on our business, financial condition, results of operations, prospects and our ability to service our debt and other obligations. If we are unable to service our indebtedness, we will be forced to adopt an alternative strategy that may include actions such as reducing capital expenditures, selling assets, restructuring or refinancing our indebtedness or seeking additional equity capital. We cannot assure that any of these alternative strategies could be effected on satisfactory terms, if at all, or that they would yield sufficient funds to make required payments on our indebtedness.

If for any reason we are unable to meet our debt service and repayment obligations, we would be in default under the terms of the agreements governing our debt, which would allow our creditors at that time to declare certain outstanding indebtedness to be due and payable, which would in turn trigger cross-acceleration or cross-default rights between the relevant agreements. In addition, our lenders could compel us to apply all of our available cash to repay our borrowings or they could prevent us from making payments on our indebtedness. If the amounts outstanding under any outstanding indebtedness were to be accelerated, we cannot assure that our assets would be sufficient to repay in full the money owed to the lenders or to our other debt holders.

We are subject to environmental laws and potential exposure to environmental liabilities. This may affect our ability to develop, sell or rent our property or to borrow money where such property is required to be used as collateral.

As a result of the acquisition of Gichner, we will use hazardous materials common to the industry in which Gichner operates. We are required to follow federal, state and local environmental laws and regulations regarding the handling, storage and disposal of these materials, including the Clean Air Act, the Clean Water Act, the Resource Conservation and Recovery Act, the Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"), and the Toxic Substances Control Act. We could be subject to fines, suspensions of production, alteration of our manufacturing processes or interruption or cessation of our operations if we fail to comply with present or future laws or regulations related to the use, storage, handling, discharge or disposal of toxic, volatile or otherwise hazardous chemicals used in our manufacturing processes. These regulations could require us to acquire expensive remediation equipment or to incur significant other expenses to comply with environmental regulations. Our failure to control the handling, use, storage or disposal of, or adequately restrict the discharge of, hazardous substances could subject us to liabilities and production delays, which could cause us to miss our customers' delivery schedules, thereby reducing our sales for a given period. We may also have to pay regulatory fines, penalties or other costs (including remediation costs), which could materially reduce our profits and adversely affect our financial condition. Permits are required for our operations, and these permits are subject to renewal, modification and, in some cases, revocation.

In addition, under environmental laws, ordinances or regulations, a current or previous owner or operator of property may be liable for the costs of removal or remediation of some kinds of petroleum products or other hazardous substances on, under, or in its property, adjacent or nearby property, or offsite disposal locations, without regard to whether the owner or operator knew of, or caused, the presence of the contaminants, and regardless of whether the practices that resulted in the contamination were legal at the time they occurred. We have incurred, and we may incur in the future, liabilities under CERCLA and other environmental cleanup laws at our current or former facilities, adjacent or nearby properties or offsite disposal locations. The costs associated with future cleanup activities that we may be required to conduct or finance may be

S-33

Table of Contents

material. The presence of, or failure to remediate properly, petroleum products or other hazardous substances may adversely affect the ability to sell or rent the property or to borrow funds using the property as collateral. Additionally, we may become subject to claims by third parties based on damages, including personal injury and property damage, and costs resulting from the disposal or release of hazardous substances into the environment.

Litigation may distract us from operating our business.

Litigation that may be brought by or against us could cause us to incur significant expenditures and distract our management from the operation of our business. Furthermore, there can be no assurance that we would prevail in such litigation or resolve such litigation on terms favorable to us, which may adversely affect our financial results and operations.

Risks Related to Investments in our Securities

We may allocate the net proceeds from this offering in ways that you and other stockholders may not approve.

We intend to use the net proceeds from this offering to fund the cash consideration payable to the stockholders of Herley in connection with our proposed acquisition thereof. In the event that the Merger is not consummated, we intend to use the net proceeds from this offering for general corporate purposes, including the acquisition of or investment in other businesses, services and technologies that are complementary to our own. In general, our management will have broad discretion in the application of the net proceeds from this offering and could spend the net proceeds in ways that do not necessarily improve our operating results or enhance the value of our common stock.

Our stock price may be volatile, and your investment could suffer a decline in value.

The stock market in general and the stock prices of government services companies in particular, have experienced volatility that has often been unrelated to or disproportionate to the operating performance of those companies. These broad market fluctuations may negatively affect the market price of our common stock. From December 27, 2009 to December 26, 2010, our closing stock price ranged from $9.46 to $14.93. You may not be able to resell your shares at or above the price you paid for them due to fluctuations in the market price of our common stock.

Factors which could have a significant impact on the market price of our common stock include, but are not limited to, the following:

•

quarterly variations in operating results;

•

announcements of new services by us or our competitors;

•

the gain or loss of significant customers;

•

changes in analysts' earnings estimates;

•

rumors or dissemination of false information;

•

pricing pressures;

•

short selling of our common stock;

•

impact of litigation and government inquiries;

•

general conditions in the market;

•

political and/or military events associated with current worldwide conflicts; and

•

events affecting other companies that investors deem comparable to us.

These and other external factors may cause the market price and demand for our common stock to fluctuate substantially, which may limit or prevent investors from readily selling their shares of common stock and may otherwise negatively affect the liquidity of our common stock. Volatility in the market price of our

S-34

Table of Contents

common stock could also subject us to securities class action litigation. We and certain of our current and former officers and directors have been named defendants in class action and derivative lawsuits. These matters and any other securities class action litigation and derivative lawsuits in which we may be involved could result in substantial costs to us and a diversion of our management's attention and resources, which could materially harm our financial condition and results of operations.

Our charter documents and Delaware law may deter potential acquirers and may depress our stock price.

Certain provisions of our charter documents and Delaware law, as well as certain agreements we have with our executives, could make it substantially more difficult for a third party to acquire control of us. These include:

•

authorizing the board of directors to issue preferred stock;

•

prohibiting cumulative voting in the election of directors;

•

prohibiting stockholder action by written consent;

•

establishing advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted on by stockholders at meetings of our stockholders;

•

Section 203 of the Delaware General Corporation Law, which prohibits us from engaging in a business combination with an interested stockholder unless specific conditions are met; and

•

agreements with a number of our executives that entitle them to payments in certain circumstances following a change in control.

We also have a stockholder rights plan which may discourage certain types of transactions involving an actual or potential change in control and may limit our stockholders' ability to approve transactions that they deem to be in their best interests. As a result, these provisions may depress our stock price.

You should not place undue reliance on forward-looking statements. Except as required by law, we assume no responsibility for updating any forward-looking statements nor do we intend to do so. Our actual results, performance or achievements could differ materially from the results expressed in, or implied by, these forward-looking statements.

USE OF PROCEEDS

We expect the net proceeds from this offering to be approximately $                million (or $                million if the underwriters exercise their option to purchase additional shares in full), after deducting underwriting discounts and commissions, as described in "Underwriting," and estimated offering expenses payable by us. We intend to use the net proceeds from this offering to fund the cash consideration payable to the stockholders of Herley in connection with our proposed acquisition thereof. In the event that the acquisition is not consummated, we intend to use the net proceeds from this offering for general corporate purposes, including the acquisition of or investment in other businesses, services and technologies that are complementary to our own and other general corporate expenses.

As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses of the proceeds from this offering. Accordingly, we will retain broad discretion over the use of such proceeds. Pending the use of the net proceeds from this offering as described above, we intend to invest the net proceeds in short-term, investment-grade securities.

DILUTION

Our net tangible book deficit on September 26, 2010 was approximately $114.9 million, or approximately $7.18 per share of common stock. Net tangible deficit per share is determined by dividing our net tangible book deficit, which consists of tangible assets less total liabilities, by the number of shares of common stock outstanding on that date. Without taking into account any other changes in the net tangible book deficit after September 26, 2010, other than to give effect to our receipt of (i) approximately $24.7 million in connection with the offering of 2,530,000 shares of our common stock pursuant to the prospectus supplement filed with the SEC on October 7, 2010, and (ii) the estimated net proceeds from the sale of                    shares of our common stock at an offering price of $       per share, less the underwriting fees

and our estimated offering expenses, our net tangible book deficit as of September 26, 2010, after giving effect to the items above, would have been approximately $        million, or $       per share. This represents an immediate decrease in the net tangible book deficit of $       per share to existing stockholders and an immediate dilution of $       per share to new investors. The following table illustrates this per share dilution:

---

---

We established the price for the sale of shares in this offering following negotiations with the underwriters based on an agreed discount of approximately                     to the prevailing market price of our common stock.

The above table is based on 18,555,661 shares of common stock outstanding, comprised of 16,025,661 shares of common stock outstanding as of September 26, 2010 and the 2,530,000 shares of common stock issued on October 7, 2010, and excludes, as of September 26, 2010:

•

1,214,314 shares of common stock issuable upon the exercise of outstanding stock options with a weighted average exercise price of $28.14 per share;

•

1,701,529 shares of common stock available for future grant under the Plans;

•

749,847 shares of common stock issuable upon the vesting and settlement of restricted stock units; and

•

100,000 shares of common stock which may be issued upon conversion of 10,000 shares of Series B Preferred Shares.

To the extent that any of these options are exercised, restricted stock units are settled, new options or restricted stock units are issued under our equity incentive plans or we issue additional shares of common stock in the future or assume outstanding options in connection with future acquisitions, including in connection with our proposed acquisition of Herley, there will be further dilution to new investors.

As a percentage of ownership, following the offering (based on 18,555,661 shares of common stock outstanding, comprised of 16,025,661 shares of common stock outstanding as of September 26, 2010 and the 2,530,000 shares of common stock issued on October 7, 2010, and assuming our existing stockholders do not purchase any shares in this offering):

•

the number of shares of our common stock held by existing stockholders would decrease from 100% to       % of the total number of shares of our common stock outstanding after this offering; and

•

the number of shares of our common stock held by new investors would be approximately       % of the total number of shares of our common stock outstanding after this offering.

Additionally, if the underwriters exercise their option to purchase additional shares in full, as described below in the section entitled "Underwriting," the following will occur:

•

the number of shares of our common stock held by existing stockholders would decrease to       % of the total number of shares of our common stock outstanding after this offering; and

•

the number of shares of our common stock held by new investors would increase to approximately       % of the total number of shares of our common stock outstanding after this offering.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL DATA

The following unaudited pro forma condensed combined financial data is intended to show how the acquisition of Herley, Gichner and HBE might have affected historical financial statements of Kratos if such acquisitions had been completed at an earlier time and was prepared based on the historical financial results reported by Kratos, Herley, Gichner and HBE. The following should be read in connection with the audited and unaudited consolidated financial statements of Herley, set forth in Annex B of this prospectus supplement, and the audited and unaudited consolidated financial statements of Kratos, which are incorporated by reference into this prospectus supplement. See "Where You Can Find Additional Information" beginning on page S-61.

The unaudited pro forma condensed combined financial statements were prepared in accordance with the regulations of the SEC. The pro forma adjustments reflecting the completion of the acquisition of Herley are based upon the acquisition method of accounting in accordance with U.S. generally accepted accounting principles ("GAAP"), and upon the assumptions set forth in the notes to the unaudited pro forma condensed combined financial statements.

During 2010, Kratos acquired Gichner and HBE. The acquisition of each of Gichner and HBE was completed on May 19, 2010 and December 15, 2010, respectively.

The unaudited pro forma condensed combined balance sheet as of September 26, 2010 combines the historical consolidated balance sheets of Kratos as of September 26, 2010, HBE as of September 30, 2010, and Herley as of October 31, 2010.

The unaudited pro forma condensed combined statements of operations for the nine months ended September 26, 2010 combine the historical consolidated statements of operations of Kratos, Herley and HBE for their respective nine months ended September 26, 2010, October 31, 2010 and September 30, 2010, and of Gichner for the three months ended March 31, 2010. The unaudited pro forma condensed combined statements of operations for the year ended December 27, 2009 combine the historical consolidated statements of operations of Kratos, Gichner and HBE for their respective years ended December 27, 2009, December 31, 2009 and December 31, 2009, and of Herley for the 12-month period ended January 31, 2010. The operating results for the 12-month period ended January 31, 2010 for Herley were derived from the quarterly operating results and annual operating results of Herley.

The unaudited pro forma condensed combined financial information also gives effect to this offering and the related debt financing.

The historical consolidated financial data has been adjusted to give effect to pro forma events that are (i) directly attributable to the acquisition of each of Gichner, HBE and Herley, (ii) factually supportable, and (iii) with respect to the statement of operations, expected to have a continuing impact on the combined results. The pro forma adjustments are preliminary and based on management's estimates of the fair value and useful lives of the assets acquired and liabilities assumed and have been prepared to illustrate the estimated effect of the acquisitions and certain other adjustments. The unaudited pro forma condensed combined financial statements do not reflect revenue opportunities, synergies or cost savings that the Company expects to realize after the acquisitions. No assurance can be given with respect to the estimated revenue opportunities and operating cost savings that are expected to be realized as a result of the acquisitions. The unaudited pro forma condensed combined financial statements also do not reflect non-recurring charges related to integration activities or exit costs that may be incurred by Kratos, Gichner or HBE in connection with the acquisitions thereof. There were no material transactions between Kratos, HBE and Gichner during the periods presented in the unaudited pro forma condensed combined financial statements that would need to be eliminated.

The unaudited pro forma condensed combined financial data is presented for illustrative purposes only and is not necessarily indicative of the financial condition or results of operations of future periods or the

financial condition or results of operations that actually would have been realized had the entities been combined during the periods presented. The unaudited pro forma condensed combined financial statements do not give effect to the potential impact of current financial conditions, regulatory matters or any anticipated synergies, operating efficiencies or cost savings that may be associated with the acquisition of Herley. These financial statements also do not include any integration costs, synergies or estimated future transaction costs, except for fixed contractual transaction costs, that the companies may incur as a result of the acquisition of Herley. In addition, as explained in more detail in the accompanying notes to the unaudited pro forma condensed combined financial statements, the preliminary acquisition-date fair value of the identifiable assets acquired and liabilities assumed reflected in the unaudited pro forma condensed combined financial statements is subject to adjustment and may vary significantly from the actual amounts that will be recorded upon completion of the acquisition of Herley.

Kratos Defense & Security Solutions, Inc.
Notes to Unaudited Pro Forma Condensed Combined Financial Statements

1.        Description of the Transaction and Other Recent Events

On February 7, 2011, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with Lanza Acquisition Co., a Delaware corporation and the Company's indirect wholly-owned subsidiary ("Merger Sub") and Herley. Assuming the closing of the transactions contemplated by the Merger Agreement, the Company will own all of the issued and outstanding capital stock of Herley, and Herley will become a direct subsidiary of the Company.

The Company estimates its cash requirements in connection with the acquisition of Herley to be approximately $318 million. On February 7, 2011, in connection with the Offer, we entered into a commitment letter (the "Commitment Letter") with Jefferies Group, Inc., Key Capital Corporation and OPY Credit Corp. (collectively, the "Committing Parties"), pursuant to which the Committing Parties have committed to provide debt financing of up to an aggregate of $307.5 million for the Offer. The commitment of the Committing Parties under the Commitment Letter is subject to customary conditions, including the absence of any material adverse effect on the financial condition of Herley or our ability to consummate the transactions described in the Commitment Letter. The amount of the commitment is subject to reduction by the amount of net proceeds that we raise in this offering; provided that the maximum amount of such reduction shall not exceed $40 million. The Company expects to use the net proceeds from this offering together with the net proceeds from the debt financing transaction to fund the purchase of Herley Common Stock in connection with the acquisition of Herley and for other corporate purposes. If the acquisition of Herley is not completed, the Company will use the net proceeds from this offering for general corporate purposes. The shares issued in the offering have been assumed to be approximately three million which results in net proceeds of $40 million assuming that the shares were issued at $13.99 which was the last reported sale price of our common stock on the NASDAQ Global Select Market on February 4, 2011.

On December 15, 2010, the Company completed the merger of Hammer Acquisition Inc., a Delaware corporation and a wholly-owned subsidiary of the Company ("Hammer Merger Sub"), with and into HBE, whereby HBE became a wholly-owned subsidiary of the Company (the "HBE Merger"). The HBE Merger was effected pursuant to an Agreement and Plan of Merger, dated October 5, 2010, by and among the Company, HBE and Hammer Merger Sub, as amended by that certain Amendment to the Agreement and Plan of Merger, dated November 13, 2010, by and among the Company, HBE and Hammer Merger Sub. The Company paid $56.6 million to acquire HBE, of which $54.9 million was paid in cash and $1.7 million of which reflects the fair value of the replacement options issued to HBE option holders.

On October 12, 2010, the Company completed a firm commitment underwritten offering of approximately 2.5 million shares of its common stock at a public offering price of $10.20 per share. The Company received gross proceeds of approximately $25.8 million and net proceeds of approximately $24.7 million after deducting underwriting fees and other offering expenses. The Company used the net proceeds from this offering to fund the purchase price for the acquisition of HBE.

2.        Basis of Presentation

The unaudited pro forma condensed combined financial statements were prepared in accordance with the regulations of the SEC. The pro forma adjustments reflecting the completion of the acquisition of Herley are based upon the acquisition method of accounting in accordance with GAAP, and upon the assumptions set forth in the notes to the unaudited pro forma condensed combined financial statements.

During 2010, Kratos acquired Gichner and HBE. The acquisition of each of Gichner and HBE was completed on May 19, 2010 and December 15, 2010, respectively.

Table of Contents

The unaudited pro forma condensed combined balance sheet as of September 26, 2010 combines the historical consolidated balance sheets of Kratos as of September 26, 2010, HBE as of September 30, 2010, and Herley as of October 31, 2010.

The unaudited pro forma condensed combined statements of operations for the nine months ended September 26, 2010 combine the historical consolidated statements of operations of Kratos, Herley and HBE for their respective nine months ended September 26, 2010, October 31, 2010 and September 30, 2010, and of Gichner for the three months ended March 31, 2010. The unaudited pro forma condensed combined statements of operations for the year ended December 27, 2009 combine the historical consolidated statements of operations of Kratos, Gichner and HBE for their respective years ended December 27, 2009, December 31, 2009 and December 31, 2009, and of Herley for the twelve month period ended January 31, 2010. The operating results for the twelve month period ended January 31, 2010 for Herley were derived from the quarterly operating results and annual operating results of Herley.

The pro forma adjustments include the application of the acquisition method of accounting under Financial Accounting Standards Board Accounting Standards Codification ("ASC") Topic 805 Business Combinations ("ASC Topic 805"). ASC Topic 805 requires, among other things, that identifiable assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date, which is presumed to be the closing date of the acquisition of Herley.

Under ASC Topic 820 Fair Value Measurements and Disclosures ("ASC Topic 820"), "fair value" is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC Topic 820 specifies a hierarchy of valuation techniques based on the nature of the inputs used to develop the fair value measures. This is an exit price concept for the valuation of the asset or liability. In addition, market participants are assumed to be unrelated buyers and sellers in the principal or the most advantageous market for the asset or liability. Fair value measurements for an asset assume the highest and best use by these market participants. Many of these fair value measurements can be highly subjective and it is also possible that other professionals, applying reasonable judgment to the same facts and circumstances, could develop and support a range of alternative estimated amounts.

The historical consolidated financial data has been adjusted to give effect to pro forma events that are (1) directly attributable to the acquisition of each of Gichner, HBE and Herley, (2) factually supportable, and (3) with respect to the statement of operations, expected to have a continuing impact on the combined results. The pro forma adjustments are preliminary and based on management's estimates of the fair value and useful lives of the assets acquired and liabilities assumed and have been prepared to illustrate the estimated effect of the acquisition and certain other adjustments. The unaudited pro forma condensed combined financial statements do not reflect revenue opportunities, synergies or cost savings that the Company expects to realize after the acquisitions. No assurance can be given with respect to the estimated revenue opportunities and operating cost savings that are expected to be realized as a result of the acquisitions. The unaudited pro forma condensed combined financial statements also do not reflect non-recurring charges related to integration activities or exit costs that may be incurred by Kratos, Gichner or HBE in connection with the acquisitions thereof. There were no material transactions between Kratos, HBE and Gichner during the periods presented in the unaudited pro forma condensed combined financial statements that would need to be eliminated.

3.        Accounting Policies

Based upon the Company's preliminary review of Herley's summary of significant accounting policies disclosed in its audited financial statements, incorporated herein by reference, the nature and amount of any adjustments to the historical financial statements of Herley to conform Herley's accounting policies to those of the Company's are not expected to be significant. See "Where You Can Find More Information."

4.        Consideration Transferred and Purchase Price Allocation

The initial consideration transferred and the aggregate purchase price to be allocated is presented in the table below (in millions).

---

(a)

Kratos expects to fund the cash payment with cash on hand and net proceeds from this offering together with the net proceeds from a debt financing transaction, as described in Note 1 above.

5.        Estimate of Assets to be Acquired and Liabilities to be Assumed

The following is a discussion of the adjustments made in connection with the preparation of the unaudited pro forma condensed combined financial statements. Each of these adjustments represents preliminary estimates of the fair values of HBE's and Herley's assets and liabilities and periodic amortization of such adjustments to the extent applicable. Actual adjustments will be made when the final fair value of HBE's and Herley's assets and liabilities is determined. Accordingly, the actual adjustments to HBE's and Herley's assets and liabilities and the related amortization of such adjustments may differ materially from the estimates reflected in the unaudited pro forma condensed combined financial statements.

The following is the preliminary estimate of the assets acquired and the liabilities assumed by Kratos reconciled to the consideration transferred (in millions):

---

---

Goodwill:    Goodwill is calculated as the excess of the acquisition date fair value of the consideration transferred over the values assigned to the identifiable assets acquired and liabilities assumed. Goodwill is not amortized but rather is subject to an annual impairment test.

Intangible assets:    Using the income approach, the Company has made a preliminary estimate of the fair value of the acquired identifiable intangible assets, which are subject to amortization. Further analysis must be performed to value those assets at fair value and allocate purchase price to those assets. As such, the value of intangible assets may differ significantly from the amount reflected on the unaudited pro forma condensed combined financial information. Amortization recorded in the statement of operations may also

differ based on the valuation of intangible assets. The following table sets forth the components of these intangible assets and their estimated useful lives (dollars in millions):

---

6.        Adjustments to Unaudited Pro Forma Condensed Combined Balance Sheet:

(a)

The sources and uses of funds relating to the acquisitions are as follows (in millions):

---

---

(b)

Reflects adjustment for current and long term deferred financing costs of $1.8 million and $9.6 million, respectively, related to issuance of debt.

(c)

Reflects adjustments to deferred taxes and goodwill as a result of the impact of indefinite lived intangibles acquired.

(d)

Reflects adjustments to goodwill (in millions):

(e)

Reflects adjustments to intangibles (in millions):

---

(f)

Reflects payment of Herley debt.

(g)

Reflects a bond premium of $15.0 million. $2.4 million is current and $12.6 is long term. The bond premium is the difference between the 10% face amount of the notes and an assumed yield to maturity of approximately 8.6% on the new issuance.

(h)

Reflects payment of Herley employee settlements of $2.4 million, of which $1.4 million is a current liability and $1.0 million is a long term liability.

(i)

Reflects the face amount of the long term debt assumed to be issued of $250.0 million offset by payment of Herley long term debt of $10.4 million.

(j)

Reflects the elimination of Herley common stock.

(k)

Reflects the elimination of the Herley and HBE additional-paid-in-capital offset by assumed net proceeds from the issuance of common stock of $64.7 million and $2.0 million related to the fair value of options assumed for Herley and HBE. (See Note 1.)

(l)

Reflects the elimination of Herley and HBE retained earnings offset by transaction costs and change in control payments of $24.0 million.

Table of Contents

7.        Adjustments to Unaudited Pro Forma Condensed Combined Statement of Operations:

(a)

Net decrease in amortization expense to reflect the adjustment for intangibles not acquired in the transactions, net of the amortization expense of identifiable intangible assets arising from the purchase price allocations. Identifiable intangible assets are being amortized using the straight-line method and their weighted average useful lives (in millions):

---

---

---

---

(b)

Reflects a reduction in stock-based compensation expense as a result of the exercise of stock options and restricted stock immediately prior to closing of the Herley and HBE transactions offset by stock-based compensation expense for stock options assumed. The net adjustment was a reduction in expense of $0.6 million for the nine months ended September 26, 2010 and $1.0 million for the year ended December 27, 2009.

S-48

---

Table of Contents

(c)

Interest expense adjustments (in millions):

---

---

In May 2010, to finance the acquisition Gichner, the Company completed a private offering of $225 million in aggregate principal amount of 10% Senior Secured Notes due 2017 and entered into a new 4-year, $25.0 million revolving credit facility, which is secured by a first priority lien on the combined entity's accounts receivable and inventory. To finance the Herley acquisition, the Company plans to issue additional 10% Senior Secured Notes due 2017. The assumed yield to maturity on the new notes is approximately 8.7%. The interest expense is based on the interest cost of the debt facilities that were the result of the Gichner acquisition and the estimated interest cost for the acquisition of Herley. A ¹/8 percent change in the interest rate on the new notes would result in a $0.3 million change in yearly interest expense.

(d)

Reflects the income tax effects of pro forma adjustments and utilization of Kratos net operating losses and tax attributes to offset tax expense that HBE and Gichner would otherwise incur on a stand-alone basis.

(e)

Reflects the issuance of 3.0 million shares related to this offering and the issuance of 2.5 million shares on October 12, 2010. (See Note 1)

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS FOR NON-U.S. HOLDERS

The following is a summary of the material U.S. federal income and estate tax considerations relevant to the purchase, ownership and disposition of our common stock by a non-U.S. holder (as defined below) as of the date hereof. This summary deals only with non-U.S. holders that acquire our common stock in this offering and hold the common stock as a capital asset.

For purposes of this summary, a "non-U.S. holder" means a beneficial owner of our common stock that is not a partnership and is not any of the following for U.S. federal income tax purposes: (i) an individual citizen or resident of the United States, (ii) a corporation (or other entity treated as a corporation) created or organized in or under the laws of the United States, any state thereof, or the District of Columbia, (iii) an estate the income of which is subject to U.S. federal income taxation regardless of its source, or (iv) a trust if (1) its administration is subject to the primary supervision of a court within the United States and one or more U.S. persons have the authority to control all of its substantial decisions, or (2) it has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

This summary is based upon provisions of the Internal Revenue Code of 1986, as amended, and regulations, rulings and judicial decisions as of the date hereof. Those authorities may be changed, perhaps retroactively, or be subject to differing interpretations, so as to result in U.S. federal tax considerations different from those summarized below. This summary does not represent a detailed description of the U.S. federal tax considerations to you in light of your particular circumstances. In addition, it does not address the U.S. federal tax considerations to you if you are subject to special treatment under the U.S. federal tax laws (including if you are a bank or other financial institution, insurance company, broker or dealer in securities, tax-exempt organization, foreign government or agency, U.S. expatriate, "controlled foreign corporation," "passive foreign investment company," or a person who holds our common stock in a straddle or as part of a hedging, conversion or constructive sale transaction). Except where noted, this summary does not address any U.S. taxes other than U.S. federal income tax. We cannot assure you that a change in law will not alter significantly the tax considerations that we describe in this summary.

If an entity classified as a partnership for U.S. federal income tax purposes holds our common stock, the tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. If you are a partnership holding our common stock, or a partner in such a partnership, you should consult your tax advisors.

If you are considering the purchase of our common stock, you should consult your own tax advisors concerning the particular U.S. federal tax consequences to you of the purchase, ownership and disposition of the common stock, as well as the consequences to you arising under the laws of any other taxing jurisdiction, including any state, local or foreign tax consequences.

Dividends

We have never declared or paid any cash dividends on our common stock and do not anticipate paying any cash dividends on our common stock in the foreseeable future. If we were to pay cash dividends in the future on our common stock, they would be subject to U.S. federal income tax in the manner described below.

Cash distributions on our common stock generally will constitute dividends for U.S. federal income tax purposes to the extent paid out of our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Distributions in excess of current and accumulated earnings and profits will be applied against and reduce a non-U.S. holder's tax basis in our common stock, to the extent thereof, and any excess will be treated as capital gain realized on the sale or other disposition of the common stock and subject to tax in the manner described below under "— Gain on Disposition of Common Stock."

S-50

---

Table of Contents

Distributions paid to a non-U.S. holder of our common stock that constitute dividends under the rules described above generally will be subject to withholding of U.S. federal income tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. However, dividends that are effectively connected with the conduct of a trade or business by a non-U.S. holder within the United States and, where an income tax treaty applies, are attributable to a U.S. permanent establishment of the non-U.S. holder, are not subject to this withholding tax, but instead are subject to U.S. federal income tax on a net income basis at applicable individual or corporate rates. Certain certification and disclosure requirements must be complied with in order for effectively connected dividends to be exempt from this withholding tax. Any such effectively connected dividends received by a foreign corporation may be subject to an additional "branch profits tax" at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

A non-U.S. holder of our common stock who is entitled to and wishes to claim the benefits of an applicable treaty rate (and avoid backup withholding as discussed below) with respect to dividends received on our common stock, generally will be required to (i) complete IRS Form W-8BEN (or an acceptable substitute form) and make certain certifications, under penalty of perjury, to establish its status as a non-U.S. person and its entitlement to treaty benefits or (ii) if the common stock is held through certain foreign intermediaries, satisfy the relevant certification requirements of applicable U.S. Treasury regulations. Special certification and other requirements apply to certain non-U.S. holders that are entities rather than individuals.

A non-U.S. holder of our common stock eligible for a reduced rate of U.S. federal withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

Gain on Disposition of Common Stock

A non-U.S. holder generally will not be subject to U.S. federal income tax with respect to gain recognized on a sale or other disposition of our common stock unless (i) the gain is effectively connected with a trade or business of the non-U.S. holder in the United States and, where a tax treaty applies, is attributable to a U.S. permanent establishment of the non-U.S. holder (in which case, for a non-U.S. holder that is a foreign corporation, the branch profits tax described above may also apply), (ii) in the case of a non-U.S. holder who is an individual, such holder is present in the U.S. for 183 or more days in the taxable year of the sale or other disposition and certain other conditions are met, or (iii) subject to certain exceptions, we are or have been a "U.S. real property holding corporation" for U.S. federal income tax purposes.

We believe we currently are not, and do not anticipate becoming, a "U.S. real property holding corporation" for U.S. federal income tax purposes.

Federal Estate Tax

Common stock held by an individual non-U.S. holder at the time of death will be included in such holder's gross estate for U.S. federal estate tax purposes, unless an applicable estate tax treaty provides otherwise.

Information Reporting and Backup Withholding

We must report annually to the IRS and to each non-U.S. holder the amount of dividends paid to such holder and the tax withheld (if any) with respect to such dividends, regardless of whether withholding was required. Copies of the information returns reporting such dividends and any withholding may also be made available to the tax authorities in the country in which the non-U.S. holder resides under the provisions of an applicable income tax treaty. In addition, dividends paid to a non-U.S. holder may be subject to backup withholding unless applicable certification requirements are met.

S-51

---

Table of Contents

Payment of the proceeds of a sale of our common stock within the United States or conducted through certain U.S. related financial intermediaries is subject to information reporting and, depending upon the circumstances, backup withholding unless the non-U.S. holder certifies under penalties of perjury that it is not a United States person (and the payor does not have actual knowledge or reason to know that the holder is a United States person) or the holder otherwise establishes an exemption.

Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against such holder's U.S. federal income tax liability provided the required information is timely furnished to the IRS.

Legislation Affecting Taxation of Common Stock Held By or Through Foreign Entities

Effective for payments made after December 31, 2012, a 30% U.S. federal withholding tax will be imposed on dividends on stock of U.S. corporations, and on the gross proceeds from the disposition of such stock, paid to a "foreign financial institution" (as specially defined for this purpose), unless such institution enters into an agreement with the U.S. Treasury to collect and provide to the U.S. Treasury substantial information regarding its U.S. account holders and certain account holders that are foreign entities with U.S. owners. A 30% U.S. federal withholding tax will also apply to dividends paid on stock of U.S. corporations and on the gross proceeds from the disposition of such stock paid to a non-financial foreign entity unless such entity provides the withholding agent with a certification that it does not have any substantial U.S. owners or a certification identifying the direct and indirect substantial U.S. owners of the entity. Under certain circumstances, a holder may be eligible for refunds or credits of such withholding taxes. Investors are urged to consult with their own tax advisors regarding the possible application of these rules to their investment in our common stock.

UNDERWRITING

Under the terms and subject to the conditions to be set forth in an underwriting agreement dated February      , 2011, by and among us and Jefferies & Company, Inc., as representative of the several underwriters, we have agreed to sell to the underwriters and the underwriters have severally agreed to purchase from us, the number of shares indicated in the table below:

---

---

The underwriting agreement provides that the obligations of the several underwriters are subject to certain conditions precedent such as the receipt by the underwriters of officers' certificates and legal opinions and approval of certain legal matters by their counsel. The underwriting agreement provides that the underwriters will purchase all of the shares if any of them are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or the underwriting agreement may be terminated. We have agreed to indemnify the underwriters and certain of their controlling persons against certain liabilities, including liabilities under the Securities Act, and to contribute to payments that the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the shares subject to their acceptance of the shares from us and subject to prior sale. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Option to Purchase Additional Shares

We have granted the underwriters an option, exercisable no later than 30 calendar days after the date of the underwriting agreement, to purchase up to an aggregate of                                             additional shares of our common stock at the public offering price, less the underwriting discounts and commissions set forth on the cover page of this prospectus supplement and as indicated below. We will be obligated to sell these shares of our common stock to the underwriters to the extent the over-allotment option is exercised. The underwriters may exercise this option only to cover over-allotments, if any, made in connection with the sale of our common stock offered by this prospectus supplement.

Commission and Expenses

The underwriters have advised us that they propose to offer our common stock directly to the public at the offering price set forth on the cover page of this prospectus supplement and to certain dealers at that price less a concession not in excess of $               per share. After the offering, the initial public offering price and the concession to dealers may be reduced by the representative. No such reduction will change the amount of proceeds to be received by the offering as set forth on the cover page of this prospectus supplement.

Table of Contents

The following table shows the per share and total underwriting discounts and commissions that we will pay to the underwriters and the proceeds we will receive before expenses. These amounts are shown assuming both no exercise and full exercise of the underwriters' option to purchase additional shares of our common stock.

---

---

We have also agreed to reimburse the underwriters for certain reasonable travel, legal and other out-of-pocket expenses.

We estimate the total offering expenses of this offering that will be payable by us, excluding the underwriting discount and commission, will be approximately $               , which includes legal costs, various other fees and reimbursement of certain of the underwriters' expenses.

No Sales of Similar Securities

We have agreed, subject to specified exceptions, not to directly or indirectly offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of, any shares of our common stock or any securities convertible into or exercisable or exchangeable for our common stock. We have also agreed not to file any registration statement, preliminary prospectus or prospectus, or any amendment or supplement thereto, under the Securities Act for any such transaction or which registers, or offers for sale, our common stock or any securities convertible into or exercisable or exchangeable for our common stock, except for registration statements on Form S-8 relating to employee benefit plans.

Certain of our executive officers and directors have agreed, subject to specified exceptions, not to directly or indirectly:

•

offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of, any shares of our common stock or securities convertible into or exercisable or exchangeable for our common stock (including, without limitation, shares of our common stock or any such securities which may be deemed to be beneficially owned by such officers and directors in accordance with the rules and regulations promulgated under the Securities Exchange Act of 1934, as the same may be amended or supplemented from time to time (such shares or securities, the "Beneficially Owned Shares"));

•

enter into any swap, hedge or other agreement or arrangement that transfers in whole or in part, the economic risk of ownership of any Beneficially Owned Shares, our common stock or securities convertible into or exercisable or exchangeable for our common stock; or

•

engage in any short selling of any Beneficially Owned Shares, our common stock or securities convertible into or exercisable or exchangeable for our common stock.

These restrictions terminate after the close of trading of the common shares on and including the 90 days after the date of this prospectus supplement.

However, subject to certain exceptions, in the event that either:

•

during the last 17 days of the 90-day restricted period, we issue an earnings release or material news or a material event relating to us occurs; or

S-54

Table of Contents

•

prior to the expiration of the 90-day restricted period, we announce that we will release earnings results during the 16-day period beginning on the last day of the 90-day restricted period,

then in either case the expiration of the 90-day restricted period will be extended until the expiration of the 18-day period beginning on the date of the issuance of an earnings release or the occurrence of the material news or event, as applicable, unless Jefferies & Company, Inc. waives, in writing, such an extension.

Notwithstanding the above agreement, one of our executive officers, Benjamin Goodwin, our President, Public Safety & Security Segment, will be permitted to surrender to us or sell on account of withholding taxes a portion of his shares of restricted stock under the Plans upon the date such taxes are due. Such surrender or sale will be disclosed on a Form 4 filed under the Exchange Act and will relate to approximately 4,000 shares.

Jefferies & Company, Inc. may, in its sole discretion and at any time or from time to time before the termination of the 90-day restricted period, without public notice, release all or any portion of the securities subject to lock-up agreements. There are no existing agreements between the underwriters and us, providing consent to the sale of shares prior to the expiration of the lock-up period.

Listing

Our common stock is traded on the NASDAQ Global Select Market under the symbol "KTOS."

Price Stabilization, Short Positions and Penalty Bids

Until the distribution of the shares of common stock is completed, SEC rules may limit the underwriters from bidding for and purchasing shares of our common stock.

In connection with this offering, the underwriters may engage in transactions that stabilize, maintain or otherwise make short sales of our common stock and may purchase our common stock on the open market to cover positions created by short sales. Short sales involve the sale by an underwriter of a greater number of shares than it is required to purchase in this offering. The underwriters may close out any short position by purchasing shares in the open market or exercising their over-allotment option.

A short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in this offering. A "stabilizing bid" is a bid for or the purchase of our common stock on behalf of the underwriters in the open market prior to the completion of this offering for the purpose of fixing or maintaining the price of the shares of our common stock. A "syndicate covering transaction" is the bid for or purchase of our common stock on behalf of the underwriters to reduce a short position incurred by the underwriters in connection with the offering.

Similar to other purchase transactions, the underwriters' purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our shares or preventing or retarding a decline in the market price of our shares. As a result, the price of our shares may be higher than the price that might otherwise exist in the open market.

In connection with this offering, the underwriters may also engage in passive market making transactions in our common stock on the NASDAQ Global Select Market in accordance with Rule 103 of Regulation M during a period before the commencement of offers or sales of shares of our common stock in this offering and extending through the completion of distribution. A passive market maker must display its bid at a price not in excess of the highest independent bid of that security. However, if all independent bids are lowered below the passive market maker's bid, that bid must then be lowered when specified purchase limits are exceeded.

Neither we, nor any of the underwriters, make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, neither we nor any of the underwriters makes any representation that the underwriters will engage in these transactions or that any transaction, if commenced, will not be discontinued without notice.

Electronic Distribution

A prospectus supplement in electronic format may be made available by e-mail or on the websites or through online services maintained by one or more of the underwriters or their affiliates. In those cases, prospective investors may view offering terms online and may be allowed to place orders online. The underwriters may agree with us to allocate a specific number of shares for sale to online brokerage account holders. Any such allocation for online distributions will be made by the underwriters on the same basis as other allocations. Other than the prospectus supplement in electronic format, the information on the underwriters' websites and any information contained in any other website maintained by any of the underwriters is not part of this prospectus supplement, has not been approved and/or endorsed by us or the underwriters and should not be relied upon by investors.

(b)

The initial expiration date of the Offer shall be the twentieth (20th) Business Day after the date that the Offer is commenced (determined pursuant to Rule 14d-1(g)(3) and Rule 14d-2 under the Exchange Act) (such date, or such subsequent date to which the expiration of the Offer is extended pursuant to and in accordance with the terms of this Agreement, the "Expiration Date"). Merger Sub shall not terminate or withdraw the Offer other than in connection with the effective termination of this Agreement in accordance with Article IX hereof. Notwithstanding the foregoing, unless this Agreement is terminated in accordance with Article IX hereof, Merger Sub shall, and Parent shall cause Merger Sub to, (i) extend the Expiration Date if, on any then scheduled Expiration Date, any of the Tender Offer Conditions is not satisfied or waived by Merger Sub, for such periods of up to five (5) Business Days at a time (or such other longer period as shall be consented to in writing by the Company) as Merger Sub may deem reasonably necessary, but, except as required by any applicable Law, rule, regulation, interpretation or position of the NASDAQ, the SEC or the staff of the SEC (the "SEC Staff") applicable to the Offer (including in connection with an increase in the Offer Price), in no event may the Expiration Date be extended pursuant to this clause (i) to a date later than the Termination Date and (ii) extend the Expiration Date for any period required by any applicable Law, rule, regulation, interpretation or position of the NASDAQ, the SEC or the SEC Staff applicable to the Offer, including in connection with an increase in the Offer Price.

Nothing in this Section 2.1(b) shall affect any termination rights contained in Article IX hereof.



(c)

Subject to the terms and conditions set forth in this Agreement and to the satisfaction or waiver of the Tender Offer Conditions, Merger Sub shall, and Parent shall cause it to, (i) promptly after the Expiration Date, accept for payment and pay for (after giving effect to any required withholding Tax pursuant to Section 2.1(e)) all shares of Company Common Stock that have been validly tendered and not properly withdrawn pursuant to the Offer (the date of acceptance for payment, the "Acceptance Date"), which acceptance shall be by written notice to the Paying Agent, (ii) promptly after the Acceptance Date, but no later than the close of business, New York City time, on the third Business Day thereafter, deposit or cause to be deposited with the Paying Agent, cash in U.S. dollars sufficient to pay the aggregate Offer Price for such accepted shares of Company Common Stock, and (iii) as soon as practicable following such deposit, cause the Paying Agent to pay for all shares of Company Common Stock so accepted for payment. In the event that the Acceptance Date occurs, but the number of shares of Company Common Stock that have been validly tendered and not properly withdrawn in the Offer, together with any shares of Company Common Stock then owned by Parent, assuming exercise of the Top-Up Option in full, is less than ninety percent (90%) of the outstanding shares of Company Common Stock on a fully diluted basis, Merger Sub may, in its sole discretion, commence a "subsequent offering period" (in accordance with Rule 14d-11 promulgated under the Exchange Act) for a number of days to be determined by Parent but not less than three (3) nor more than twenty (20) Business Days to acquire additional outstanding shares of Company Common Stock.

Merger Sub will, concurrently with the exercise of the Top-Up Option, give written notice to the Company that as promptly as practicable following such exercise, Merger Sub intends to (and Merger Sub will, and Parent will cause Merger Sub to, as promptly as practicable after such exercise) consummate the Merger in accordance with Section 253 of the DGCL as contemplated by Section 3.9. The Top-Up Option shall not be exercisable, and the Company shall not be obligated to deliver the Top-Up Option Shares, if (i) the number of shares of Company Common Stock issuable pursuant to the Top-Up Option exceeds the number of authorized shares of Company Common Stock available for issuance and not otherwise reserved for issuance for outstanding Company Options or other obligations of the Company, (ii) the exercise of the Top-Up Option and the issuance and delivery of the Top-Up Option Shares are prohibited by any applicable Law, (iii) any judgment, injunction, order or decree shall be in effect prohibiting the exercise of the Top-Up Option or the delivery of the Top-Up Option Shares in respect of such exercise (excluding any rule or regulation of the NASDAQ), (iv) immediately upon exercise of the Top-Up Option and the issuance of the Top-Up Option Shares, the number of shares of Company Common Stock owned, directly or indirectly, by Parent and Merger Sub (excluding shares of Company Common Stock tendered in the Offer pursuant to guaranteed delivery procedures as to which delivery has not been completed as of the time of exercise of the Top-Up Option) does not constitute one share more than ninety percent (90%) of the number of shares of Company Common Stock that will be outstanding on a fully diluted basis immediately after the issuance of the Top-Up Option Shares, (v) the issuance of Top-Up Option Shares pursuant to the Top-Up Option would require approval by the Company's stockholders under applicable Law (other than pursuant to the rules and regulations of the NASDAQ) or (vi) Merger Sub has not accepted for payment all shares of Company Common Stock validly tendered in the Offer and not properly withdrawn and has not deposited or caused to be deposited with the Paying Agent cash sufficient to pay the aggregate Offer Price for all accepted shares of Company Common Stock. The parties shall cooperate to ensure that the issuance of the Top-Up Option Shares is accomplished consistent with all applicable Laws (other than pursuant to the rules and regulations of the NASDAQ), including compliance with an applicable exemption from registration of the Top-Up Option Shares under the Securities

Act. The Top-Up Option shall terminate upon the earlier to occur of (i) the Effective Time and (ii) termination of this Agreement in accordance with Article IX.

(c)

In the event that Merger Sub wishes to exercise the Top-Up Option in accordance with this Section 2.3, Merger Sub shall give the Company prior written notice specifying in such notice: (i) the number of Shares that Merger Sub intends to purchase pursuant to the Top-Up Option; (ii) the manner in which Parent or Merger Sub intends to pay the applicable exercise price; and (iii) the place and time at which the closing of the purchase of such Top-Up Option Shares by Merger Sub is to take place, with the time for the closing being not more than five (5) Business Days after the exercise of the Top-Up Option. The Company shall, as soon as practicable following receipt of such notice, notify Merger Sub of the number of shares of Company Common Stock then outstanding, the number of shares of Company Common Stock then outstanding on a Fully-Diluted Basis and the number of Top-Up Option Shares. At the closing of the purchase of the Top-Up Option Shares, Merger Sub shall pay the Company the aggregate purchase price payable for the Top-Up Option Shares pursuant to this Section 2.3, and the Company shall cause to be issued to Merger Sub a certificate (or evidence of shares in book-entry form) representing the Top-Up Option Shares. The aggregate purchase price payable for the Top-Up Option Shares may be paid either (i) entirely in cash or (ii) at the election of Merger Sub or Parent, by paying in cash an amount equal to not less than the aggregate par value of the Top-Up Option Shares and by Merger Sub executing and delivering to the Company a full recourse promissory note having a principal amount equal to the balance of the aggregate purchase price for the Top-Up Option Shares. Any such promissory note shall bear interest at the rate of five percent (5%) per annum, shall mature on the first (1st) anniversary of the date of execution and delivery of such promissory note and may be prepaid at any time and from time to time, in whole or in part, without premium or penalty. Merger Sub's obligations under any such promissory note shall be guaranteed by Parent. Without the prior written consent of the Company, the right to exercise the Top-Up Option granted pursuant to this Agreement shall not be assigned by Merger Sub except to any direct or indirect wholly owned Subsidiary of Parent. Any attempted assignment in violation of this Section 2.3(c) shall be null and void.



(d)

Each of Parent and Merger Sub acknowledges that the Top-Up Option Shares that Merger Sub may acquire upon exercise of the Top-Up Option will not be registered under the Securities Act and will be issued in reliance upon an exemption thereunder for transactions not involving a public offering. Each of Parent and Merger Sub represents and warrants to the Company that Merger Sub is, and will be upon the exercise of the Top-Up Option Shares, an "accredited investor," as defined in Rule 501 of Regulation D promulgated under the Securities Act. Each of Parent and Merger Sub represents, warrants and agrees that the Top-Up Option and the Top-Up Option Shares to be acquired upon exercise of the Top-Up Option are being and will be acquired by Merger Sub for the purpose of investment and not with a view to, or for resale in connection with, any distribution thereof (within the meaning of the Securities Act). Any certificates evidencing Top-Up Option Shares shall include any legends required by applicable securities Laws.



(e)

Any dilutive impact on the value of the shares of Company Common Stock as a result of the issuance of the Top-Up Option Shares will not be taken into account in any determination of the fair value of any Dissenting Shares pursuant to Section 262 of the DGCL as contemplated by Section 4.1(d).

The payment of any transfer, documentary, sales, use, stamp, registration, value added and other such Taxes and fees (including any penalties and interest) incurred by a holder of Company Common Stock in connection with the Merger, and the filing of any related Tax Returns and other documentation with respect to such Taxes and fees, shall be the sole responsibility of such holder.



(d)

In no event shall the holder of any surrendered certificates (or evidence of shares in book-entry form) representing Company Common Stock be entitled to receive interest on any of the Merger Consideration.



(e)

If the payment equal to the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered certificate (or evidence of shares in book-entry form) formerly evidencing shares of Company Common Stock is registered on the stock transfer books of the Company, it shall be a condition of payment that the certificate (or evidence of shares in book-entry form) so surrendered shall be properly endorsed or otherwise be in proper form for transfer and that the Person requesting such payment shall have paid all transfer and other taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the certificate (or evidence of shares in book-entry form) surrendered, or shall have established to the satisfaction of the Paying Agent and Parent that such taxes either have been paid or are not applicable.



(f)

At any time following the twelfth (12th) month after the Effective Time, Parent shall be entitled to require the Paying Agent to deliver to it any funds which had been made available to the Paying Agent and not disbursed to holders of shares of Company Common Stock (including, without limitation, all interest and other income received by the Paying Agent in respect of all funds made available to it), and, thereafter, such holders shall be entitled to look to Parent (subject to abandoned property, escheat and other similar laws) only as general creditors thereof with respect to any Merger Consideration that may be payable upon due surrender of the certificates (or evidence of shares in book-entry form) held by them.

Any net profit resulting from, or interest or income produced by, such investments shall be payable to Parent or an affiliate of Parent as Parent directs; provided, however, that any net loss resulting from such investments shall be promptly reimbursed by Parent to the Exchange Fund upon demand by the Paying Agent. No investment of the Merger Consideration funds shall relieve Parent, the Surviving Corporation or the Paying Agent from making payments required by this Article IV.

(a)

The Company shall take all such action as may be required to fully vest each Company Option as of immediately prior to the Effective Time. If the holder so elects in writing, each In-The-Money Company Option shall be canceled at the Effective Time, in exchange for a payment by the Company, in cash, within five (5) Business Days of the Effective Time, equal to the product of (i) the excess, if any, of the Offer Price over the per share exercise price of the In-The-Money Company Option, and (ii) the number of shares subject to the Company Option, less applicable withholdings. To the extent that a holder of an In-The-Money Company Option does not elect that a particular Company Option may be treated in the manner described in the prior sentence, that Company Option shall instead be treated as an "Out-Of-The-Money Company Option" for all purposes.

(b)

At the Effective Time, all rights with respect to Company Common Stock under each Out-Of-The-Money Company Option shall be converted into and become rights with respect to Parent Common Stock, and Parent shall assume each such Out-Of-The-Money Company Option in accordance with the terms and conditions (as in effect as of the date of this Agreement) of the stock option plan under which it was issued, as amended, if applicable, and the terms and conditions of the stock option agreement by which it is evidenced, as amended, if applicable. From and after the Effective Time, (i) each Out-Of-The-Money Company Option assumed by Parent may be exercised solely for shares of Parent Common Stock, (ii) the number of shares of Parent Common Stock subject to each such Out-Of-The-Money Company Option shall be equal to the number of shares of Company common stock subject to such Out-Of-The-Money Company Option immediately prior to the Effective Time multiplied by the Option Exchange Ratio, rounding down to the nearest whole share, (iii) the per share exercise price under each such Out-Of-The-Money Company Option

shall be adjusted by dividing the per share exercise price under such Out-Of-The-Money Company Option by the Option Exchange Ratio and rounding up to the nearest cent, and (iv) any restriction on the exercise of any such Out-Of-The-Money Company Option shall continue in full force and effect and the term, exercisability, and other provisions of such Out-Of-The-Money Company Option shall otherwise remain unchanged; provided, however, that each Out-Of-The-Money Company Option assumed by Parent in accordance with this Section 4.3(b) shall, in accordance with its terms, be subject to further adjustment as appropriate to reflect any stock split, stock dividend, reverse stock split, reclassification, recapitalization or other similar transaction effected subsequent to the Effective Time. The "Option Exchange Ratio" shall be equal to the fraction obtained by dividing the Offer Price by the average closing sales price for one share of Parent Common Stock on NASDAQ for the ten (10) trading-day period ending on the first business day immediately preceding the date hereof.

(c)

Each restricted stock award granted under any compensation plan or arrangement of the Company and outstanding immediately prior to the Effective Time ("Company Restricted Stock") shall be cancelled at the Effective Time in exchange for the Merger Consideration payable in respect of such stock.



(d)

Prior to the Effective Time, the Company shall take all actions reasonably necessary to effect the measures contemplated by this Section 4.3, including but not limited to adoption of any plan amendments, offering to enter into the elections contemplated by Section 4.3(a), seeking Company Board approval and/or seeking any consents, and to ensure that, on and after the Effective Time, no holder of an In-The-Money Company Option or Company Restricted Stock has any further rights with respect thereto (other than to receive the payments provided for in this Section 4.3) and that no holder of an Out-Of-The-Money Company Option has any further rights with respect thereto (other than the rights provided for in this Section 4.3).

4.4

Withholding Rights.    Notwithstanding any provision contained herein to the contrary, each of the Paying Agent, the Surviving Corporation, Parent and their respective agents shall be entitled to deduct and withhold from the Merger Consideration, or the amounts described in Section 4.3, otherwise payable to any Person pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of any federal, state, local or foreign Tax Law. If the Paying Agent, the Surviving Corporation, Parent or any of their respective agents, as the case may be, so withholds amounts, and pays over such amounts to the appropriate Taxing Authority, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock in respect of which the Paying Agent, the Surviving Corporation, Parent or the agent, as the case may be, made such deduction and withholding.

Sufficient Funds; Financing.

(a)

Parent has, and shall have at the Acceptance Date, available to it sufficient cash and cash equivalents to permit Merger Sub to perform all of its obligations under this Agreement and to consummate all the transactions contemplated hereby, including, without limitation, acquiring all the outstanding shares of Company Common Stock in the Offer and the Merger. Parent and Merger Sub expressly acknowledge and agree that their obligations hereunder are not subject to any conditions, express or implied, regarding their ability to obtain financing (or to obtain financing on acceptable terms) for the consummation of the Offer or the Merger.

(b)

None of the transactions contemplated hereby, including the Offer and the Merger, will require the consent from any lender or the holder or any notes, bonds or other debt instruments pursuant to which Parent or Merger Sub, or any of their respective Affiliates, are obligated or bound. To the extent that any such consents were required to be obtained prior to the execution this Agreement, Parent has provided to the Company true, correct and complete copies of such consents.

(c)

Parent has received a commitment letter (the "Commitment Letter") executed by the parties specified therein (the "Lenders"), pursuant to which the Lenders have committed, upon the terms and subject to the conditions set forth therein, to provide debt financing in the amounts set forth therein for the purpose of (inter alia) funding the Offer, the Merger and the other transactions contemplated hereby.

The obligations of the Lenders to fund the commitments under the Commitment Letter are not subject to any conditions, other than the conditions expressly set forth in the Commitment Letter.

Without limiting the generality of the foregoing, the Company acknowledges and agrees that any violation of the restrictions set forth in the preceding sentence by any Representative of the Company or any of its Subsidiaries shall be deemed to constitute a breach of this Section 7.2 by the Company.

(b)

Notwithstanding anything to the contrary in Section 7.2(a), if at any time on or after the date of this Agreement and prior to the Offer Closing, the Company or its Representatives receives an Acquisition Proposal from a Third Party which did not result from a breach of Section 7.2(a), and the Company Board, or any committee thereof, determines in good faith, after consulting with outside legal and financial advisors, that any such Acquisition Proposal constitutes, or would reasonably be expected to lead to, a Superior Proposal and the Company Board, or any committee thereof, determines in good faith, after consultation with outside legal counsel, that the failure to take such action would reasonably be expected to be a breach of its fiduciary duties under applicable Law, then the Company and its Representatives may (A) furnish, pursuant to an Acceptable Confidentiality Agreement, information (including non-public information) and/or access with respect to the Company and its Subsidiaries to the Person or group of Persons who has made such Acquisition Proposal; provided that the Company shall provide or make available, to the extent not previously provided or made available to Parent or its Representatives, to Parent any non-public information with respect to the Company or any of its Subsidiaries that is provided to the Third Party making such Acquisition Proposal prior to or substantially concurrently with the time it is provided or made available to such Third Party; and (B) engage in or otherwise participate in discussions and/or negotiations directly or through its Representatives with the Person or group of Persons making such Acquisition Proposal. Notwithstanding anything to the contrary contained in Section 7.2(a), the Company shall be permitted to grant a waiver or release to any Person or group of Persons subject to an Acceptable Confidentiality Agreement for the sole purpose of allowing such Person or group of Persons to submit an Acquisition Proposal that the Company Board, or any committee thereof, determines in good faith is reasonably likely to lead to a Superior Proposal if the Company Board determines that the failure to take such action would reasonably be expected to be a breach of its fiduciary duties under applicable Law. For the purposes of this Agreement, "Acceptable Confidentiality Agreement" means any confidentiality agreement that contains provisions that are no less favorable in the aggregate to the Company than those contained in the Confidentiality Agreement, provided that any such agreement shall permit the Company to comply with the terms of this Section 7.2. The Company also will promptly request each Person that has executed, within 12 months prior to the date of this Agreement, a confidentiality agreement in connection with its consideration of a possible Acquisition Transaction or equity investment to, subject to the terms of the applicable confidentiality agreement, return or destroy all confidential information heretofore furnished to such Person by or on behalf of the Company and, in the event that such Person refuses to

In addition, it is understood and agreed that, for purposes of this Agreement (including Article IX), a factually accurate public statement by the Company that describes the Company's receipt of an Acquisition Proposal and the operation of this Agreement with respect thereto, or any "stop, look and listen" communication by the Company Board pursuant to Rule 14d-9(f) of the Exchange Act, or any similar communication to the stockholders of the Company, shall not, in and of itself, constitute a Board Recommendation Change or a withdrawal or modification, or proposal by the Company Board to withdraw or modify, such Company Board's recommendation of this Agreement or the transactions contemplated hereby, or an approval or recommendation with respect to any Acquisition Proposal.

rounded up to the nearest whole number, constituting at least a majority of the directors, on the Company Board as will give Parent representation on the Company Board equal to the product of (i) the total number of directors on the Company Board (giving effect to the number of directors designated by Parent and elected or appointed to the Company Board pursuant to this sentence) multiplied by (ii) the percentage that such number of shares of Company Common Stock beneficially owned by Parent, Merger Sub or any of their Affiliates (including, for purposes of such percentage, the shares of Company Common Stock that are accepted for payment pursuant to the Offer and that the aggregate Offer Price has been deposited for) bears to the total number of shares of Company Common Stock then outstanding, and the Company shall use commercially reasonable efforts to, upon Parent's request and subject to the terms of the Company Certificate and the Company Bylaws, promptly, at Parent's election, either increase the size of the Company Board or seek and accept the resignation of such number of directors as is necessary to enable Parent's designees to be elected to the Company Board and to cause Parent's designees to be so elected. At such times, subject to Section 7.5(c), the Company will cause individuals designated by Parent to constitute the number of members of each Committee of the Company Board, rounded up to the next whole number, that represents the same percentage as such individuals represent on the Company Board, other than any Committee established to take action under this Agreement which Committee shall be composed only of directors who qualify as independent for purposes of the continued listing requirements of the NASDAQ.

If no Continuing Director remains prior to the Effective Time, a majority of the members of the Company Board at the time of the execution of this Agreement shall be entitled to designate three persons to fill such vacancies; provided, that such individuals shall not be employees or officers of the Company, Parent or Merger Sub and shall be reasonably satisfactory to Parent, and such persons shall be deemed independent directors for purposes of this Agreement.

In addition, from and after the Effective Time, Parent shall cause the Company and the Surviving Corporation to pay any expenses (including, but not limited to, fees and expenses of legal counsel, experts and litigation consultants, as well as any appeal bonds) of any Indemnified Party under this Section 7.9 (including in connection with enforcing the advancement, indemnity and other obligations referred to in this Section 7.9) as incurred to the fullest extent to which such Indemnified Party is entitled to such payment as of the date of this Agreement; provided, that the person to whom expenses are advanced provides an undertaking to repay such advances to the extent, and only to the extent, required by applicable Law.

An Indemnified Party shall have the right, but not the obligation, to assume and control the defense of any litigation, claim or proceeding relating to any acts or omissions covered under this Section 7.9 with counsel selected by the Indemnified Party, which counsel shall be reasonably acceptable to Parent; provided, however, that Parent (i) shall be permitted to participate in the defense of such claim at its own expense and (ii) shall not be liable for any settlement effected without Parent's written consent, which consent shall not be unreasonably withheld, conditioned or delayed. In the event that any claim for advancement or indemnification is asserted or made, all rights to advancement or indemnification in respect of such claim shall continue until the disposition of such claim.

The obligations set forth in this Section 7.9 shall not be terminated, amended or otherwise modified in any manner that adversely affects any Indemnified Party and their heirs and representatives, without the affected Indemnified Party or other Person consenting in writing to such termination, amendment or modification (it being expressly agreed that the Indemnified Parties to whom this Section 7.9 applies shall be third party beneficiaries of this Section 7.9).

10.6

Governing Law.    This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to the principles of conflict of laws (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

upon each party thus served. Each of the parties hereby irrevocably waives, and agrees not to attempt to assert or assert, by way of motion or other request for leave from any such Delaware state or federal court, as a defense, counterclaim or otherwise, in any action, suit or proceeding for the interpretation or enforcement hereof or of any such document, (i) the defense of sovereign immunity, (ii) any claim that it is not personally subject to the jurisdiction of the above-named courts for any reason other than the failure to serve process in accordance with this Section 10.7, (iii) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iv) to the fullest extent permitted by applicable law that (A) the suit, action or proceeding in any such court is brought in an inconvenient forum, (B) the suit, action or proceeding is not maintainable in such court, (C) the venue of such suit, action or proceeding is improper or inappropriate and (D) this Agreement, or the subject matter hereof, may not be enforced in or by such courts. Each of the parties to this Agreement irrevocably agree that all claims with respect to such action or proceeding shall be heard and determined in such Delaware state or federal court. The parties agree that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Law.

(b)

Notwithstanding anything to the contrary expressed or implied in this Agreement, each party acknowledges and agrees that: (i) an action or proceeding to enforce or collect upon any order or judgment issued by any of the courts specified in Section 10.7(a) in any action or proceeding contemplated by Section 10.7(a) may be brought in any jurisdiction where such party, or any direct or indirect subsidiary of such party, is located or has assets; and (ii) each party irrevocably waives any objection to registration, exequatur, execution, enforcement or collection of any order or judgment within subclause (i) in any such enforcement or collection action or proceeding.



(c)

EACH PARTY HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY SUIT, ACTION OR OTHER PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY HERETO CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF ANY ACTION, SUIT OR PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH PARTY MAKES THIS WAIVER VOLUNTARILY AND (iv) EACH PARTY AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10.7.



(d)

The parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and that any defense in any action for specific performance that a remedy at law would be adequate is hereby waived. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement exclusively in the Delaware Court of

Chancery and any state appellate court therefrom within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware), in addition to any and all other rights and remedies at law or in equity, and all such rights and remedies shall be cumulative. Any requirements for the securing or posting of any bond with such remedy are waived. The parties further agree not to assert that a remedy of specific performance is unenforceable, invalid, contrary to Law or inequitable for any reason.

documents delivered pursuant hereto and the Confidentiality Agreement) constitutes the entire agreement among the parties with respect to the subject matter hereof and supersedes all prior agreements and understandings, both written and oral, among the parties hereto, or any of them, with respect to the subject matter hereof. There are no warranties, representations or other agreements between the parties in connection with the subject matter of this Agreement, except as specifically set forth in this Agreement. This Agreement and any rights, interests and obligations hereunder may not be assigned by any of the parties hereto by operation of law or otherwise without the prior written consent of each of the other parties, and any attempted assignment without such consent shall be void and of no effect, except that Parent may assign all or any of its rights and obligations hereunder to any direct or indirect wholly-owned Subsidiary of Parent; provided, however, that no such assignment will relieve Parent from any of its obligations hereunder.

10.10

Parties in Interest.    This Agreement shall be binding upon and inure solely to the benefit of each party hereto and their respective successors and permitted assigns. Nothing in this Agreement, express or implied is intended to or shall confer upon any other Person any rights, benefits or remedies of any nature whatsoever under or by reason of this Agreement; provided, however, that the rights, benefits and remedies granted to Indemnified Parties pursuant to Section 7.9 shall inure to the benefit of and be enforceable by the Indemnified Parties. Notwithstanding the immediately preceding sentence, following the Effective Time, the provisions of Article IV relating to the payment of the Merger Consideration shall be enforceable by holders of certificates.

10.11

Severability.    If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in a manner adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible.

10.12

Disclosure Schedules.    The parties hereto agree that any reference in a particular Section of either the Company Disclosure Schedule or the Parent Disclosure Schedule shall be deemed to be an exception to (or, as applicable, a disclosure for purposes of) (i) the representations and warranties (or covenants, as applicable) of the relevant party that are contained in the corresponding Section of this Agreement and (ii) any other representations and warranties of such party that is contained in this Agreement (in either case (i) or (ii), regardless of the absence of an express reference or cross-reference in a particular Section of this Agreement or a particular Section of either the Company Disclosure Schedule or Parent Disclosure Schedule), but only if the relevance of that reference as an exception to (or a disclosure for purposes of) such representations and warranties would be reasonably apparent. The disclosure of any matter in any section of either the Company Disclosure Schedule or the Parent Disclosure Schedule shall not be deemed to constitute an admission or indication by the disclosing party, or to otherwise imply, that any such matter is material for the purposes of this Agreement. No party shall use, either individually or in the aggregate, the fact of the inclusion of any such item or information in any sections of the Company Disclosure Schedule or the Parent Disclosure Schedule in any disagreement, dispute or controversy between the parties as to whether any obligation, item, information or matter is or is not material, or may give rise to a change or effect that could have a Company Material Adverse Effect or a Parent Material Adverse Effect. Nor shall any disclosure on a section be deemed to constitute an acknowledgment that any such matter is required to be disclosed. No disclosure on any section relating to a possible breach or violation of any contract or applicable Law shall be construed as an admission or indication that any breach or violation exists or has actually occurred. The disclosure of any matter in any section of either the Company Disclosure Schedule or the Parent Disclosure Schedule is not to be treated as constituting

64

Table of Contents

or implying any representation, warranty, assurance or undertaking by the disclosing party not expressly set out in this Agreement, nor to be treated as adding to or extending the scope of any of the disclosing party's representations or warranties in this Agreement.

10.13

Parent Guarantee.    Parent agrees to take all action necessary to cause Merger Sub and the Surviving Corporation, as applicable, to comply in all respects with each of the representations, warranties, covenants, obligations, agreements and undertakings made or required to be performed by Merger Sub under this Agreement, the Offer, the Merger and the transactions contemplated hereby and thereby. As a material inducement to the Company's willingness to enter into this Agreement and perform its obligations hereunder, Parent hereby unconditionally guarantees the due, prompt and faithful performance and discharge by Merger Sub and the Surviving Corporation of each of the covenants, terms, obligations and undertakings that are required to be performed by Merger Sub and/or the Surviving Corporation under this Agreement, the Offer, the Merger and the transactions contemplated hereby and thereby, including any such obligations, covenants, terms, conditions and undertakings that are required to be performed discharged or complied with following the Control Time and hereby represents, acknowledges and agrees that any breach of, or other failure to perform, any such representation, warranty, covenant, obligation, agreement or undertaking of Merger Sub or the Surviving Corporation shall also be deemed to be a breach or failure to perform by Parent, and the Company shall have the right, exercisable in its sole discretion, to pursue any and all available remedies it may have arising out of any such breach or nonperformance directly against either or both of Parent and Merger Sub in the first instance. This is a guarantee of payment and performance and not collectability. Parent hereby waives diligence, presentment, demand of performance, filing of any claim, any right to require any proceeding first against Merger Sub or the Surviving Corporation, as applicable, protest, notice and all demands whatsoever in connection with the performance of its obligations set forth in this Section 10.13.

10.14

Return of Exclusivity Payment.    Within one Business Day of the earlier to occur of (a) the Acceptance Date and (b) the termination of the Agreement by (i) Parent pursuant to Section 9.3; or (ii) the Company pursuant to Section 9.4(c), the Company shall pay to Parent an amount equal to the Exclusivity Payment by wire transfer of same day funds to an account designated by Parent.

REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

Board of Directors and Shareholders
Herley Industries, Inc.

We have audited Herley Industries, Inc. and Subsidiaries' (a Delaware Corporation) (the "Company") internal control over financial reporting as of August 1, 2010, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for maintaining effective internal control over financial reporting and for its assertion of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We did not audit internal control over financial reporting of General Microwave Israel Corp. and subsidiary ("GMIC"), a wholly owned subsidiary, whose financial statements reflect total assets and revenues constituting 27 and 23 percent, respectively, of the related consolidated financial statement amounts as of and for the fifty-two-weeks ended August 1, 2010. GMIC's internal control over financial reporting was audited by other auditors whose report has been furnished to us, and our opinion, insofar as it relates to GMIC's internal control over financial reporting in relation to the Company taken as a whole, is based solely on the report of the other auditors.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit and the report of other auditors provide a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent, or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, based on our audit and the report of other auditors, Herley Industries, Inc. maintained, in all material respects, effective internal control over financial reporting as of August 1, 2010, based on criteria established in Internal Control — Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet, statement of operations, statement of shareholders' equity, and statement of cash flows for the fifty-two weeks ended August 1, 2010 and our report dated October 14, 2010 expressed an unqualified opinion.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders of
General Microwave Israel Corp.

We have audited the internal control over financial reporting of General Microwave Israel Corp. and subsidiary (the "Company") as of August 1, 2010, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of August 1, 2010, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of the Company and its subsidiary as of August 1, 2010 and August 2 2009, the related statements of operations, changes in shareholders' equity and cash flows for the fifty-two weeks ended August 1, 2010 and for the fifty-two weeks ended August 2 2009, and our report dated October 4, 2010 expressed an unqualified opinion on those financial statements.

Board of Directors and Shareholders
Herley Industries, Inc.

We have audited the accompanying consolidated balance sheet of Herley Industries, Inc. (a Delaware corporation) (the "Company") and subsidiaries as of August 1, 2010, and the related consolidated statements of operations, shareholders' equity, and cash flows for the fifty-two week period then ended. Our audit of the basic financial statements included the financial statement schedule listed in the index appearing under Item 15(b)(2). These financial statements and financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audit. We did not audit the consolidated financial statements of General Microwave Israel Corporation and its wholly-owned subsidiary ("GMIC"), whose financial statements reflect total assets and revenues constituting 27 and 23 percent, respectively, of the related consolidated financial statement amounts as of and for the fifty-two weeks ended August 1, 2010. Those statements were audited by other auditors, whose report thereon has been furnished to us, and our opinion, insofar as it relates to the amounts included for GMIC, is based solely on the report of the other auditors.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit and the report of the other auditors provide a reasonable basis for our opinion.

HERLEY INDUSTRIES, INC. AND SUBSIDIARIES


NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE A — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

1.    Nature of Operations and Recent Events

Herley Industries, Inc. ("Herley"), a Delaware corporation, and its wholly-owned subsidiaries (collectively the "Company") are engaged in the design, development and manufacture of microwave technology solutions for the defense, aerospace and medical industries worldwide with four domestic and three foreign manufacturing facilities and two engineering offices in the U.S. Herley's corporate office is in Lancaster, Pennsylvania. Herley's primary facilities include: Herley Lancaster; Herley New England; Herley Israel; Microsystems, Inc. ("MSI"); Herley-CTI; Herley GMIC Eyal ("Eyal"); and EW Simulation Technology ("EWST"). In the first quarter of fiscal 2009, the Company sold Innovative Concepts, Inc. ("ICI") (see Note C).

In July 2010, in connection with the legal matters discussed in Note F — Commitments and Contingencies, Litigation, the Company reached an agreement to settle all securities class actions originally filed in 2006, and subsequently consolidated under the caption: In re Herley Industries, Inc. Securities Litigation, Docket No. 06-cv-2596 (JRS). As previously disclosed, between June 2006 and August 2006, the Company and certain of its current and former officers and directors (the "Individual Defendants") were named as defendants in five related class actions alleging violations of the federal securities laws. Those cases were subsequently consolidated into one class action on behalf of a purported class of all persons who purchased or otherwise acquired shares of stock of the Company during the period October 1, 2001 through June 14, 2006 (the "Class"). At all times during the pendency of the litigation, the Company and the Individual Defendants steadfastly maintained that the claims raised in the securities class action were without merit, and vigorously contested those allegations. As part of the settlement, the Company and the Individual Defendants continue to deny any liability or wrongdoing under the securities laws. The terms of the settlement provide for, in part, the dismissal of the litigation against the Company and all of the Individual Defendants, and the creation by the Company of a $10 million settlement fund. The fund will be allocated, after deduction of court-ordered expenses, such as attorneys' fees and expenses, settlement administration costs and any applicable taxes, among members of the settlement class who submit valid proofs of claims. Upon final approval of the settlement by the Court, in August 2010 the Company paid $10 million, which is included in Accounts payable and accrued expenses on the Consolidated Balance Sheet as of August 1, 2010, out of existing cash reserves to create the settlement fund.

In May, 2010 the Company reached an agreement to settle all stockholder derivative actions originally filed in 2006 in the United States District Court for the Eastern District of Pennsylvania at Docket No. 06-CV-2964 (JRS). The consolidated derivative complaint, filed on January 12, 2007, alleged that current and former directors violated their fiduciary obligations in connection with certain actions or decisions in their capacities as officers or directors of the Company. All of the defendants previously denied any wrongdoing and, under the settlement agreement, the Company and the other defendants continued to deny any breach of fiduciary duties or any other improper actions. Under the terms of the settlement, as approved by the Court, the Company has agreed to institute certain corporate governance practices relating to the Board of Directors structure, directors' independence, and nomination and election procedures for directors, related party transactions, director stock ownership, and oversight policies. The Company's Board is committed to the implementation of best practices in the area of corporate governance and believes that the agreed upon practices are consistent with that commitment. In addition, the Court awarded plaintiffs' counsel the sum of $975,000, which is included in Accounts payable and accrued expenses on the Consolidated Balance Sheet as of August 1, 2010, for fees and costs in pursuit of the consolidated derivative action. The Company paid this award in August 2010.

NOTE A — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

In February 2010, the Company settled its litigation with its Director and Officers insurance carrier for an aggregate settlement amount under the policy of $4.0 million. Under the terms of the settlement and release, the insurance carrier is not liable to any of the insured defendants, or any other insured under the policy, for any other payment under the policy in regard to the securities class action and derivative action litigation, and the policy is deemed exhausted. The Company received the settlement payment of $1.7 million in February 2010, which was net of the $2.3 million that had previously been advanced.

Effective January 8, 2010, David H. Lieberman resigned as the Company's Chairman of the Board of Directors. Mr. Lieberman was appointed to the Company's Board of Directors on July 22, 2009 and elected as an executive, serving in the capacity of Chairman of the Board. In connection with his election as Chairman, Mr. Lieberman was awarded 100,000 shares of restricted common stock which were to vest in 2014, subject to accelerated vesting under certain circumstances, and annual compensation of $250,000. Having fulfilled various initiatives, the Company and Mr. Lieberman determined that it would be in the mutual best interests for the Company and Mr. Lieberman to transition to a new Chairman of the Board and for Mr. Lieberman to engage in other business opportunities. During his Chairmanship, Mr. Lieberman was able to achieve, either alone or along with others, results which exceeded the Company's expectations, with respect to both the benefits to the Company and the time period during which these benefits were able to be realized. In addition, as a result of his resignation, Mr. Lieberman's restricted stock will not vest, and, thus, he will forego the potential value of the restricted stock previously granted to him. In light of the value of Mr. Lieberman's achievements on behalf of, and his contributions to, the Company, the Company entered into an agreement with Mr. Lieberman under which he received a performance payment in the amount of $900,000.

2.    Fiscal Year

The Company's fiscal year ends on the Sunday closest to July 31. Normally each fiscal year consists of fifty-two weeks, but every five or six years the fiscal year will consist of fifty-three weeks. Fiscal year 2010 consists of fifty-two weeks ended August 1, 2010 ("fiscal 2010"); fiscal year 2009 consists of fifty-two weeks ended August 2, 2009 ("fiscal 2009"); and fiscal year 2008 consists of fifty-three weeks ended August 3, 2008 ("fiscal 2008").

3.    Basis of Financial Statement Presentation and Accounting Estimates

The consolidated financial statements include the accounts of Herley Industries, Inc. and its subsidiaries, all of which are wholly-owned. All significant inter-company accounts and transactions have been eliminated in consolidation. The presentation of financial statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make certain estimates and assumptions that affect the reported amounts of assets, liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and reported amounts of revenues and expenses during the reporting periods.

These judgments can be subjective and complex, and consequently actual results could differ from those estimates and assumptions. The most significant estimates include: valuation and recoverability of goodwill and long-lived assets (see Notes A-9 and A-10); income taxes; recognition of revenue and costs on production contracts; and the valuation of inventory, accrual of litigation settlements and other contingencies and stock-based compensation costs. Each of these areas requires the Company to make use

HERLEY INDUSTRIES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

NOTE A — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

of reasoned estimates including estimating the cost to complete a contract, forecasted cash flows, the net realizable value of its inventory and the market value of its products. Changes in estimates can have a material impact on the Company's financial position and results of operations.

4.    Cash and Cash Equivalents

The Company considers all liquid investments with an original maturity of three months or less at the date of acquisition to be cash equivalents. Short-term investments are recorded at the amortized cost plus accrued interest, which approximates market value. The Company limits its credit risk to an acceptable level by evaluating the financial strength of institutions at which significant investments are made and based upon credit ratings. The Company had cash balances in excess of amounts insured by the FDIC as of August 1, 2010 and August 2, 2009. In addition, the Company had cash balances in foreign countries of approximately $9,393,000 and $7,840,000 as of August 1, 2010 and August 2, 2009, respectively.

5.    Concentration of Credit Risk/Trade Accounts Receivable and Related Accounts

Financial instruments, which potentially subject the Company to credit risk, consist primarily of trade accounts receivable. Trade accounts receivable are principally from the U.S. Government, major U.S. Government contractors, several foreign governments, and domestic customers in the defense, aerospace and medical industries. Credit is extended based on an evaluation of the customer's financial condition, and generally, collateral is not required. In many cases, irrevocable letters of credit accompanied by advanced payments are received from foreign customers, and progress payments are received from domestic customers. The Company performs periodic credit evaluations of its customers and maintains reserves for potential credit losses. As of August 1, 2010 and August 2, 2009, a reserve for doubtful accounts of approximately $418,000 and $262,000, respectively, are reflected in the consolidated balance sheets as a deduction from trade accounts receivable. Historically, the write-off of uncollectible trade accounts receivable has been immaterial.

The asset "Costs incurred and income recognized in excess of billings on uncompleted contracts" represents revenues recognized in excess of amounts billed. The liability "Billings in excess of costs incurred and income recognized on uncompleted contracts" represents amounts billed in excess of revenues earned. Included in these two categories are unbilled amounts which are recorded under the percentage-of-completion method and are recoverable from the customer upon shipment of the product, presentation of billings or completion of the contract. Unbilled amounts are expected to be collected within one year.

6.    Inventories

Inventories, other than inventory costs relating to long-term contracts and programs, are stated at lower of cost (principally first-in, first-out) or market. Inventory costs relating to long-term contracts and programs are stated at the actual production costs, including factory overhead, reduced by amounts identified with revenue recognized on units delivered or progress completed. Inventory costs relating to long-term contracts and programs are reduced by any amounts in excess of estimated realizable value. As is customary in the defense industry, inventory is partially financed by progress payments. The un-liquidated balance of the progress payments is shown as a reduction in the carrying amount of inventory. An estimate for obsolete and excess inventory is also provided as a reduction of the carrying value of inventory.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

NOTE A — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

7.    Property, Plant and Equipment

Property, plant and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are provided principally by the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized over the shorter of their economic lives or the lease term. Rent holidays and scheduled rent increases under operating leases are recognized on a straight-line basis over the lease term; including the rent holiday period. Gains and losses arising from the sale or disposition of property, plant and equipment are included in income from operations.

8.    Computer Software

Internal use software, which consists primarily of an integrated manufacturing and financial reporting package, is stated at cost less accumulated amortization and is amortized using the straight-line method over its estimated useful life, generally eight years.

9.    Goodwill and Intangible Assets

The Company accounts for its acquired goodwill and intangible assets in accordance with the authoritative guidance for business combinations and intangibles. In accordance with the standards, purchased goodwill must be evaluated for impairment on an annual basis. Goodwill and other intangibles with indefinite lives are not amortized.

Testing for impairment of goodwill is performed in two steps: (i) the Company determines impairment by comparing the fair value of its single reporting unit with its carrying value, and (ii) if impairment is indicated, the Company measures the amount of impairment loss by comparing the implied fair value of goodwill with the carrying amount of that goodwill. The Company has performed its annual impairment evaluation as of August 1, 2010 based on the implied fair value using its current market capitalization, which, in an active market for its common stock, the Company considers a reasonable indication of implied fair value. At August 1, 2010, the market capitalization was above the Company's carrying value, and the Company concluded no additional evaluation was required since there was no indication of an impairment of goodwill as of August 1, 2010. Due to the overall macroeconomic environment in fiscal 2009 and the depressed market capitalization of the Company, the Company proceeded to step two of the process to evaluate its goodwill impairment using the income approach and the market approach, as well as a weighted blend of each of the fair value approaches. Based upon these collective analyses, the Company concluded that there was an impairment of goodwill as of August 2, 2009 in the amount of $42,050,000, which was charged to operations in the fourth quarter of fiscal 2009.

The changes in the carrying amount of goodwill for fiscal 2009 and 2010 are as follows (in thousands):

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

NOTE A — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

The Company entered into a license and development agreement in April 2005 to license millimeter wave technology for military applications from Xytrans, Inc. ("Xytrans"). The technology acquired includes exclusive access to a portfolio of patents and trade secrets that improve the cost and performance of millimeter wave subsystems that are used in weapons and radar systems. The Company began to amortize the costs associated with this agreement in fiscal 2008 over the estimated economic life of approximately eight years. In the fourth quarter of fiscal 2009, the Company reevaluated the resources that it intended to utilize to pursue the marketing of products related to the license, performed a test for impairment of the license and determined that the fair value of the license on a discounted cash flow basis approximated $700,000 and recorded an impairment charge of $2,101,000, which is included in "Impairment of goodwill and other intangible assets" in the Consolidated Statements of Operations.

The Company has performed its annual impairment evaluation for its other intangible assets with indefinite lives and determined that these were not impaired as of August 1, 2010. The Company amortizes the cost of other intangibles over their estimated useful lives. Amortizable intangible assets may also be tested for impairment if indications of impairment exist.

The carrying amounts of intangible assets as of August 1, 2010 and August 2, 2009 are as follows (in thousands):

---

Amortization expense related to intangibles for fiscal 2010, 2009, and 2008 was approximately $1,389,000, $2,727,000, and $2,249,000, respectively.

10. Long-Lived Assets

The Company accounts for long-lived assets using a probability weighted cash flow estimation approach to evaluate the recoverability of the carrying amount of long-lived assets. The Company considers a business to be held for sale when management approves and commits to a formal plan to actively market a business for sale. Upon designation as held for sale, the carrying value of the assets of the business are recorded at the lower of their carrying value or their estimated fair value, less cost to sell. Results of operations of a business classified as held for sale are reported as discontinued operations when (a) the operations and cash flows of the business will be eliminated from ongoing operations as a result of the sale and (b) the Company will not have any significant continuing involvement in the operations of the business after the sale.

In the fourth quarter of fiscal 2009, the Company recorded a charge of approximately $345,000 on the abandonment of fixed assets in connection with the closure of the Company's manufacturing facility in Farmingdale, New York.

11. Advance Payments and Billings in Excess of Costs Incurred

The Company receives advances, performance-based payments and progress payments from customers which may exceed costs incurred on certain contracts.

12. Revenue and Cost Recognition

The Company recognizes revenue when products are shipped and the customer takes ownership and assumes risk of loss, collection of the relevant receivable is probable, persuasive evidence of an arrangement exists and the sales price is fixed or determinable. It is the policy of the U.S. Government to ensure that (a) its contracts include inspection and other quality requirements, including warranty clauses when appropriate, that are determined necessary to protect the Government's interest, (b) supplies tendered by contractors meet contract requirements; and (c) Government contract quality assurance is conducted before acceptance (except as otherwise provided in the Federal Acquisition Regulations), by or under the direction of Government personnel. The Company, as a U.S. Government contractor, is required to control the quality of its products and to tender to the Government only those products that meet the contract requirements. Accordingly, the Company's Government contracts include provisions that require its products to pass quality inspection prior to acceptance by the Government. Revenue is not recognized until the products pass quality inspection and are accepted by the customer. In the event the Government's acceptance occurs at destination, revenue is recognized at shipment if it can be demonstrated that the

B-16

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

NOTE A — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

delivered products meet all of the specified criteria prior to customer acceptance. Payments received from customers in advance of product delivery are recorded as advance payments on contracts until earned.

Most of our customer contracts are firm, fixed price contracts, providing for a predetermined fixed price for the products sold, regardless of the costs incurred. A certain percentage of revenues are derived from long-term, fixed price contracts. Revenues and estimated profits, including contract claims and unpriced change orders, are recognized on these long-term contracts using the percentage-of-completion method of accounting and are based on estimated completion to date (the total contract amount multiplied by the percentage of performance, based on total costs incurred in relation to total estimated cost at completion). In September 2009, the Company settled a matter related to claims and unpriced change orders in connection with changes in scope issues on a contract and engineering costs related to the contract resulting in a charge to cost of products sold of approximately $331,000 and a reduction in net sales of approximately $2,752,000.

Prospective losses on long-term contracts are based upon the anticipated excess of manufacturing costs over the selling price of the remaining units to be delivered and are recorded in the period when first determinable. Actual losses could differ from those estimated due to changes in the ultimate manufacturing costs and contract terms.

Contract costs include all direct material and labor costs and those indirect costs related to contract performance. Selling and administrative costs are charged to expense as incurred.

13. Product Development

The Company's primary efforts are focused on engineering design and product development activities rather than pure research. The cost of these development activities, including employees' time and prototype development, was approximately $16,825,000, $22,517,000, and $20,723,000 in fiscal 2010, 2009, and 2008, respectively, and are included in cost of products sold. Amounts paid by customers toward these product development activities were approximately $7,462,000, $10,458,000 and $2,598,000 in fiscal 2010, 2009 and 2008, respectively, and are included in net sales.

Expenditures for Company-sponsored research and development projects and bid and proposal costs are expensed as incurred. Customer-sponsored research and development projects performed under contracts are accounted for as contract costs as the work is performed.

14. Income Taxes

Income taxes are accounted for by the asset and liability approach. Deferred tax assets and liabilities represent the expected future tax consequences when the reported amounts of assets and liabilities are recovered or paid, based on tax laws and rates as currently enacted. They arise from temporary differences between the financial reporting and tax bases of assets and liabilities and are adjusted for changes in tax laws and tax rates when those changes are enacted. A valuation allowance is provided to offset deferred tax assets if, based on the available evidence, it is more likely than not that some or all of the deferred tax asset will not be realized. The provision (benefit) for income taxes represents the total of income taxes payable (receivable) for the current year, the net change in deferred tax assets and liabilities and the change in the liability for unrecognized tax benefits.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

NOTE A — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Deferred tax assets pertaining to excess tax benefits on the exercise of stock options and the corresponding credit to additional paid-in capital are recorded in the year in which the related tax deduction reduces taxes payable, pursuant to the accounting standard for stock based compensation. The Company has elected the "With-and-without approach" regarding ordering of excess tax benefits to determine whether the excess tax benefit reduces taxes payable in the current year. Under this approach, the windfall tax benefits would be recognized in additional paid-in capital only if an incremental tax benefit is realized after considering all other tax benefits presently available to the Company.

On July 30, 2007, the Company adopted the accounting standard for uncertain tax positions. The cumulative effect of applying this standard resulted in a reclassification of $3.1 million of income tax liabilities (including interest and penalties of $.7 million) from current to non-current liabilities. The total amount of unrecognized tax benefits could increase or decrease due to audit settlements, tax examination activities and application of the recognition and measurement criteria under the standard with respect to new tax positions or existing tax positions for which there has been a change in the applicable facts and circumstances. The Company has elected to reflect interest and penalties attributable to income taxes, to the extent they arise, as a component of its income tax provision or benefit, as well as its outstanding income tax assets and liabilities.

The Company has identified its federal tax return and its state tax return in Pennsylvania as major tax jurisdictions. The Company is also subject to multiple other state and foreign jurisdictions. The Company's evaluation of FIN 48 tax matters was performed for all tax years subject to examination and believes that its income tax positions and deductions would be sustained on audit and does not anticipate any adjustments, other than those identified above, which would result in a material change to its financial position.

15. Share-Based Compensation

The Company has various fixed stock option plans which are described in Note O that provide for the grant of stock options to eligible employees and directors.

The Company accounts for share-based compensation utilizing the fair value recognition guidance related to share-based payment. Such guidance requires the Company to measure the cost of employee services received in exchange for equity share options granted based on the grant-date fair value of the options. The cost is recognized as compensation expense over the requisite service period for each separately vesting portion of the options. Compensation costs included in operating expenses in fiscal 2010, 2009 and 2008 were approximately $358,000, $462,000 and $990,000, respectively. Option grants have been valued using a Black-Scholes option valuation model.

Income tax benefits relating to the exercise of stock options during fiscal 2010, 2009 and 2008 amounted to approximately $893,000, $212,000 and $91,000, respectively. Income tax benefits relating to the exercise of stock options are classified as a financing cash inflow in the Company's Consolidated Statements of Cash Flows.

The aggregate value of unrecognized compensation costs related to unvested options as determined using a Black-Scholes option valuation model, was approximately $189,000 (net of estimated forfeitures), which is expected to be recognized over a weighted-average period of 1.47 years.

NOTE A — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

During fiscal 2010, the Company granted 10,000 non-qualified stock options with a fair value of approximately $43,000. Additionally, the Company issued 100,000 and 5,000 shares of restricted stock to the Chairman of the Board of Directors and a Senior Vice President respectively, which were valued at the date of grant using the market price of the stock. The restricted stock awards have a value of approximately $1,492,000 and vest in equal installments over 5 years and 3 years respectively. Options for 467,000 shares of common stock were exercised at an average price of $10.46 per share and 395,200 options were forfeited during the year.

The total intrinsic value of options exercised during fiscal 2010, 2009 and 2008 was approximately $2,232,000, $554,000 and $237,000 respectively.

The weighted average fair value of stock options on the date of grant, and the assumptions used to estimate the fair value of stock options issued during the fiscal periods presented are as follows:

---

---

The expected life of options granted during the periods presented above is based on the Company's historical share option exercise experience using the historical expected term from vest date. The expected volatility of the options granted is determined using historical volatilities based on historical stock prices. The risk-free interest rate is determined using the yield available for zero-coupon U.S. Government issues with a remaining term equal to the expected life of the options. The Company has never paid a dividend. The forfeiture rate is based on the Company's historical experience.

16. Foreign Currency Translation

Financial statements of foreign subsidiaries are prepared in their respective functional currencies and translated into United States dollars using exchange rates at the balance sheet date for assets and liabilities and a monthly average rate during the year for revenues, costs and expenses. Net gains or losses resulting from the translation of foreign financial statements are charged or credited directly to the foreign currency translation component of "Accumulated other comprehensive income" in the accompanying Consolidated Statements of Shareholders' Equity. Transaction gains and losses resulting from transactions entered into under contracts in a currency other than the subsidiary's functional currency are accounted for on a transactional basis as a credit or charge to operations.

17. Derivatives

The Company recognizes all derivatives in its Consolidated Balance Sheet at fair value. On the date the derivative instrument is entered into, the Company generally designates the derivative as either (1) a hedge

B-19

HERLEY INDUSTRIES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

NOTE A — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

of the fair value of a recognized asset or liability, or of an unrecognized firm commitment ("fair value hedge") or (2) a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability ("cash flow hedge"). The Company entered into an interest rate swap in October 2001 with a bank, which it recognized as a cash flow hedge. Changes in the fair value of a derivative that is designated as, and meets all the required criteria for, a cash flow hedge are recorded in accumulated other comprehensive income (loss) and reclassified into earnings as the underlying hedged item affects earnings.

18. Comprehensive Income (Loss)

The Company reports comprehensive income (loss) in its Consolidated Statements of Shareholders' Equity, which includes net income (loss), unrealized gain (loss) on an interest rate swap, net of related income taxes; and foreign currency translation gain (loss). Substantially all the amount included in other comprehensive income (loss) relates to the effects of foreign exchange translation gains and losses. No adjustment has been made for income taxes since substantially all translation gains and losses relate to the permanent investment in the foreign subsidiary.

19. Dividend Policy

The Company has not paid cash dividends in its history. The Company's Board of Directors evaluates its dividend policy based on its financial condition, profitability, cash flow, capital requirements and the outlook of its business.

20. Advertising Costs

The Company expenses advertising costs as incurred. Advertising costs in fiscal 2010, 2009, and 2008 were $75,000, $72,000, and $233,000, respectively.

21. New Accounting Pronouncements

In April 2010, the Financial Accounting Standards Board issued ASU 2010-17, "Revenue Recognition — Milestone Method." The amended guidance provides the criteria that should be met for determining whether the milestone method of revenue recognition is appropriate for research and development transactions. The amended guidance is effective prospectively for milestones achieved in the Company's fiscal period ending August 1, 2010. This amendment does not have any impact on the Company's financial position, results of operations, or cash flows.

In February 2010 the FASB issued ASU 2010-09, "Subsequent Events" that removed the requirement for SEC filers to disclose the date through which an entity has evaluated subsequent events. This change removes potential conflicts with current SEC guidance. This amendment clarifies the intended scope of the reissuance disclosure provisions, is effective upon issuance and had no impact on the Company's financial position, results of operations, or cash flows.

In October 2009, the Financial Accounting Standards Board issued ASU 2009-13, "Multiple Deliverable Revenue Arrangements." This amended guidance enables companies to account for products or services (deliverables) separately rather than as a combined unit in certain circumstances. The amended guidance will be effective prospectively for revenue arrangements entered into or materially modified in the

Company's fiscal period ending August 1, 2010. This amendment has no significant impact on the Company's financial position, results of operations, or cash flows.

Other new accounting pronouncements issued but not effective until after August 1, 2010 are not expected to have a significant effect on the Company's financial position, results of operations, or cash flows.

NOTE B — BUSINESS COMBINATION

The Company entered into an Asset Purchase Agreement ("Asset Agreement"), dated as of August 1, 2008, to acquire the business and certain assets, subject to the assumption of certain liabilities, of Eyal Industries ("Eyal"), a privately-held Israeli company, for $30,000,000. The transaction closed on September 16, 2008. The business operates as a wholly-owned subsidiary of General Microwave Israel (1987) Ltd. Eyal is a leading supplier of a broad range of innovative, high reliability RF, microwave and millimeter wave components and customized subsystems for the global defense industry. Based in Kibbutz Eyal, Israel, the company has approximately 130 employees as of August 1, 2010. Eyal's core capabilities include complex integrated microwave assemblies and "off-the-shelf" components for radar, ESM, ECM and communication systems which complement and expand the Company's current product line. Eyal's customers and programs further strengthen the Company's presence in the international marketplace. Funding for the purchase was provided through a $20,000,000 loan under the Company's existing credit facility (which was repaid in fiscal 2010) and a term loan in the amount of $10,000,000 through a bank in Israel. The term loan is payable in quarterly installments of $250,000 over a period of 10 years with interest at LIBOR plus 1.5%.

The acquisition has been accounted for under the purchase method. The results of operations of Eyal are included in the Consolidated Financial Statements from September 1, 2008 (the designated "effective date").

The allocation of the aggregate purchase price (including acquisition costs of approximately $427,000), based on a detailed review of the fair value of assets acquired and liabilities assumed including the fair value of identified intangible assets is as follows (in thousands):

Discontinued operations

On September 18, 2008, the Company executed a stock purchase agreement (the "Agreement") with a foreign defense company to divest its ICI subsidiary located in McLean, Virginia. ICI is a communications technology development firm specializing in research, design, development, production, and support of wireless data communications products and services. On November 10, 2008, the Company sold the stock of ICI for approximately $15,000,000 in cash, of which a balance of approximately $726,000 is held in escrow as security for certain indemnification obligations. The escrow funds are currently in dispute as a result of alleged misrepresentations by the Company under the Agreement. The sale of ICI is presented as discontinued operations in the Consolidated Statements of Operations.

The following results of operations of ICI have been presented as discontinued operations in the Consolidated Statements of Operations (in thousands):

In accordance with authoritative guidance for "Accounting for Impairment or Disposal of Long-Lived Assets," management reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable based on estimated future undiscounted cash flows. If so indicated, an impairment loss would be recognized for the difference between the carrying amount of the asset and its fair value. For fiscal 2010 and 2009, there were no impairment charges for property, plant and equipment.

Litigation

In July 2010, the Company reached an agreement to settle all securities class actions originally filed in 2006, and subsequently consolidated under the caption: In re Herley Industries, Inc. Securities Litigation, Docket No. 06-CV-2596 (JRS). As previously disclosed, between June 2006 and August 2006, the Company and certain of its current and former officers and directors (the "Individual Defendants") were named as defendants in five related class actions alleging violations of the federal securities laws. Those cases were subsequently consolidated into one class action on behalf of a purported class of all persons who purchased or otherwise acquired shares of our stock during the period October 1, 2001 through June 14, 2006 (the "Class"). At all times during the pendency of the litigation, the Company and the Individual Defendants have steadfastly maintained that the claims raised in the securities class action were without merit, and have vigorously contested those allegations. As part of the settlement, the Company and the Individual Defendants continue to deny any liability or wrongdoing under the securities laws. The terms of the settlement provide for, in part, the dismissal of the litigation against the Company and all of the Individual Defendants, and the creation by the Company of a $10 million settlement fund. The fund will be allocated, after deduction of court-ordered expenses, such as attorneys' fees and expenses, settlement administration costs and any applicable taxes, among members of the settlement class who submit valid proofs of claim. Upon final approval of the settlement by the Court, in August 2010 the Company paid $10 million out of existing cash reserves to create the settlement fund.

In May, 2010 the Company reached an agreement to settle all stockholder derivative actions originally filed in 2006 in the United States District Court for the Eastern District of Pennsylvania at Docket No. 06-CV-2964 (JRS). The consolidated derivative complaint, filed on January 12, 2007, alleged that current and former directors violated their fiduciary obligations in connection with certain actions or decisions in their capacities as officers or directors of the Company. All of the defendants previously denied any wrongdoing and, under the settlement agreement, the Company and the other defendants continue to deny any breach of fiduciary duties or any other improper actions. Under the terms of the settlement, as approved by the Court, the Company has agreed to institute certain corporate governance practices relating to the Board of Directors structure, directors' independence, and nomination and election procedures for directors, related party transactions, director stock ownership, and oversight policies. The Company's Board is committed to the implementation of best practices in the area of corporate governance and believes that the agreed upon practices are consistent with that commitment. In addition, the Court awarded plaintiffs' counsel the sum of $975,000 for fees and costs in pursuit of the consolidated derivative action. The Company paid this award in August 2010.

In February 2010, the Company settled the litigation with its insurance carrier related to coverage under its directors' and officers' insurance policy for an aggregate settlement amount under the policy of $4.0 million. Under the terms of the settlement and release, the insurance carrier is not liable to any of the insured defendants, or any other insured under the policy, for any other payment under the policy in regard to the securities class action and derivative action litigation, and the policy is deemed exhausted. The Company received a settlement payment of $1.7 million in February 2010, which was net of $2.3 million that had previously been advanced.

By letter dated May 28, 2009, the Company was advised that a contract with General Microwave Corporation, a wholly owned subsidiary of the Company, doing business as Herley Farmingdale ("GMC") in the aggregate amount of approximately $4,900,000 was being terminated for default. By letter dated

June 1, 2009, the customer demanded a return of approximately $3,800,000, which represented an alleged progress payment made under the contract to GMC. On June 8, 2009, GMC filed suit against EDO Communications and Countermeasures, Inc. doing business as ITT Force Protection Systems ("EDO") in the United States District Court for the Eastern District of New York (the "New York Action") seeking a Declaratory Judgment, pursuant to 28 U.S.C. § 2201 et. seq. and for breach of contract related to EDO's decision to terminate the contract for default. On August 13, 2009, EDO filed suit against GMC and the Company in the Superior Court of California, Ventura County, for breach of contract, unjust enrichment, and money had and received (the "California Action"). On October 8, 2009, all parties entered into an agreement to settle this matter. Under the terms of the settlement, the Company paid $2,000,000 to EDO and the parties mutually agreed to a termination of the purchase order for convenience without further liability to either party. The Company incurred total costs of $8,645,000 and received a net payment on the contract described above after return of the $2,000,000 previously mentioned. As a result of the settlement agreement disclosed above, the Company recorded a total loss of $6,833,000, of which $2,534,000 was previously reserved.

The Company is involved in various other legal proceedings and claims which arise in the ordinary course of its business. While any litigation contains an element of uncertainty, management believes that the outcome of such other litigation will not have a material adverse effect on the Company's financial position or results of operations. Among such legal proceedings is an action brought against the Company by a competitor in October, 2009. This action alleges that, through the actions of three former employees of the plaintiff, the Company improperly obtained trade secrets to unfairly compete against the plaintiff in seeking and ultimately winning certain contracts with third parties. Also named as defendants in this action are Micro Systems, Inc., a subsidiary of the Company, and the three former employees of the plaintiff, two of whom are current or former employees of Micro Systems, Inc.

The action alleges misappropriation of trade secrets and seeks $2,000,000 in compensatory damages, and an unspecified sum in punitive damages and legal fees. The Company has vigorously defended this action and denies any allegation of improperly obtaining and/or misappropriating the plaintiff's trade secrets or proprietary information. Discovery in this case has commenced and the anticipated trial date for the action is May of 2011. At this stage of the proceedings, it is not possible to predict what, if any, liability the Company may have from this action. The parties are currently in settlement discussions in an effort to attempt to resolve the matter before both sides incur significant legal fees and costs. Disclosure of this action is being made at this time in light of the anticipated trial date and the current settlement discussions.

Stand-by Letters of Credit

The Company maintains a letter of credit facility in connection with a revolving credit agreement with two banks that provides for the issuance of stand-by letters of credit and requires the payment of a fee of 1.5% per annum (as amended October 2009) of the amounts outstanding under the facility. The facility expires March 31, 2012. At August 1, 2010, stand-by letters of credit aggregating approximately $6,859,000 were outstanding under this facility (see Note H), of which approximately $4,728,000 reduces the amount of credit available under the line of credit.

The tax effects of temporary differences that give rise to significant items comprising deferred income tax assets and liabilities are as follows (in thousands):

---

Management has determined, based upon the available evidence, that it is more likely than not that all of the Company's deferred tax assets, net of a valuation allowance of approximately $1,150,000, related to certain foreign net operating loss carry-forwards due to uncertainty regarding the Company's ability to realize them in the future, will be realized.

The Company has not recorded deferred income taxes on unremitted earnings in foreign subsidiaries that are considered to be reinvested indefinitely. These earnings relate to ongoing operations and were approximately $22,418,000 as of August 1, 2010.

As of August 1, 2010, the Company's unrecognized tax benefits, that if recognized would affect the Company's effective tax rate, were approximately $6,159,000. The Company recognizes potential accrued interest related to unrecognized tax benefits in income tax expense. At August 1, 2010 and August 2, 2009, the combined amount of accrued interest related to tax positions taken or to be taken on the Company's tax returns and recorded as part of the reserves for uncertain tax positions was $187,000 and $48,000, respectively. Management does not anticipate that it is reasonably possible that the amount of unrecognized tax benefits will significantly change in the next twelve months.

As of August 1, 2010, the Company was no longer subject to income tax examinations for taxable years before fiscal year 2006 in the case of U.S. federal and state taxing jurisdictions. The Company believes that its income tax positions and deductions would be sustained on audit and does not anticipate any adjustments, other than those identified above, which could result in a material change to its financial position.

As of August 1, 2010, the Company has available net operating loss carry-forwards for state and U. S. Federal income tax purposes of approximately $32,190,000 and $17,400,000, respectively, with expiration dates through 2028. Unused research and development credits of approximately $1,937,000, with expiration dates through 2029, are available for U. S. Federal income tax purposes, as well as alternative minimum Federal tax credits of approximately $43,000. The Company has received all Federal tax refunds related to net operating carry-back claims that were filed in December 2009.

NOTE I — EMPLOYMENT SETTLEMENT AGREEMENTS

Effective October 12, 2006 and as a condition to entering into an Administrative Agreement with the Department of the Navy the Company entered into an agreement with its former Chairman at the time to terminate the employment agreement between the Company and him dated as of July 29, 2002 and modified on December 9, 2003. Under the terms of the agreement he received payments totaling $9,461,528, with $3,000,000 paid upon the effective date of the agreement and sixty-four (64) consecutive monthly payments of $100,000, commencing on January 1, 2007 and a final payment of $61,528 on May 1, 2012 as evidenced by a non-interest bearing promissory note dated effective October 12, 2006. In the event of a "change of control" of the Company as defined in the employment agreement, all remaining payments due under the promissory note become immediately due and payable. In addition, he received his bonus of $636,503 for fiscal year 2006, and shall be entitled to receive medical care reimbursement and insurance, including life insurance, in accordance with the original terms of his employment agreement. The agreement also provides that all outstanding stock options previously issued to him, which are all vested and fully exercisable, shall continue to be exercisable by him or, following his death, by his designated beneficiaries, on or before the expiration date of the specific option.

On June 25, 2009, a Special Committee of the Board of Directors authorized an accelerated payment to the former Chairman under the terms of his agreement with the Company. The event which caused acceleration was a change in control of the Company as defined in the agreement as the ownership of 20% or more of the outstanding voting securities of the Company. The triggering event caused the acceleration of approximately $3,362,000 otherwise payable over the next 34 months so that the full amount became immediately payable. Of this amount, approximately $3,055,000 has previously been expensed by the Company. A charge to operations of approximately $307,000, representing imputed interest, was recorded in the consolidated financial statements during the fourth quarter of fiscal 2009.

Effective July 22, 2009, the Company entered into an agreement with Myron Levy, then Chairman and Chief Executive Officer of the Company, terminating his employment agreement. The agreement provides that in full satisfaction of all prior, current and future obligations to Mr. Levy under the employment agreement, Mr. Levy received an immediate lump sum payment of $4,705,000 (which was paid in August 2009) and thereafter monthly payments of $100,000 commencing on September 1, 2009 for thirty-five consecutive months through July 1, 2012. Payments are through a non-interest bearing promissory note.

Mr. Levy also continues as a consultant to the Company for three years at an annual compensation of $50,000 and is to receive certain other benefits, including medical reimbursement and insurance in accordance with the original terms of his employment agreement. The agreement also provides that all outstanding stock options previously issued to him which are all vested and fully exercisable shall continue to be exercisable by him or, following his death, by his designated beneficiaries, on or before the expiration date of the specific option.

Aggregate costs of approximately $8,679,000 under the agreement with Mr. Levy, including the initial cash payment of $4,705,000, payments due under the note of approximately $3,500,000, payments due under the consulting agreement of $150,000, medical and life insurance benefits of approximately $241,000 (all discounted at an imputed interest rate of 3.5%) and the fair value of the modification of the stock options of approximately $256,000 (using the Black-Scholes option valuation model), was recorded in the consolidated financial statements during the fourth quarter of fiscal 2009.

Effective August 1, 2009, the Company entered into an agreement with Jeffrey L Markel, then Chief Operating Officer of the Company, terminating his employment agreement. The Agreement provides that, in full satisfaction of all prior, current and future obligations to Mr. Markel under the employment agreement, Mr. Markel was to receive an immediate lump sum payment of approximately $1,370,000 (which was paid in August 2009). Mr. Markel also continues as a consultant to the Company for three years at an annual compensation of approximately $67,000 and is to receive certain other benefits through July 31, 2011, including medical reimbursement in accordance with the original terms of his employment agreement. The agreement also provides that all outstanding stock options previously issued to him shall vest immediately and become fully exercisable for a period of ninety days following the end of his consulting period.

Aggregate costs of approximately $1,874,000 under the agreement with Mr. Markel, including the initial cash payment of approximately $1,370,000, payments due under the consulting agreement of $200,000, medical and other benefits of approximately $52,000 (all discounted at an imputed interest rate of 3.5%) and the unamortized fair value of the stock options of approximately $262,000 was recorded in the consolidated financial statements during the fourth quarter of fiscal 2009.

Effective January 8, 2010, David H. Lieberman resigned as a director and Chairman of the Board of Directors of the Company. Mr. Lieberman was appointed to the Company's Board of Directors on July 22, 2009 and elected as an executive, serving in the capacity of Chairman of the Board. In connection with his election as Chairman, Mr. Lieberman was awarded 100,000 shares of restricted common stock which were to vest in 2014, subject to accelerated vesting under certain circumstances, and annual compensation of $250,000. Having fulfilled various initiatives, the Company and Mr. Lieberman determined that it would be in their mutual best interests for the Company to transition to a new Chairman of the Board and for Mr. Lieberman to engage in other business opportunities. During Mr. Lieberman's Chairmanship, Mr. Lieberman was able to achieve, either alone or along with others, results which exceeded the Company's expectations, with respect to both the benefits to the Company and the time period during which these benefits were able to be realized. In addition, as a result of his resignation, Mr. Lieberman's restricted stock will not vest, and, thus, Mr. Lieberman will forego the potential value of the restricted stock. In light of the value of Mr. Lieberman's achievements on behalf of, and his contributions to the Company, the Company entered into an agreement with Mr. Lieberman under which he received a performance payment in the amount of $900,000.

NOTE K — EMPLOYEE BENEFIT PLANS

In August 1985, the Board of Directors approved an Employee Savings Plan ("Plan") which qualified as a thrift plan under Section 401(k) of the Internal Revenue Code ("Code"). Effective August 1, 2006, the Plan was amended to allow employees to elect salary deferrals up to the maximum dollar amounts permissible under Code Section 402(g), not to exceed the limits of Code Section 401(k), 404 and 415. For the Plan year beginning August 1, 2005, the Plan was amended to be considered a "Safe Harbor" plan, where a contribution will be made to eligible participants in an amount equal to 100% of the amount of each participant's elective deferral that does not exceed 3% of compensation, plus 50% of the amount of the elective deferral that exceeds 3% of compensation up to a maximum contribution of 5% of compensation. Under the Safe Harbor provision, all contributions are 100% vested when made. Additional Company

contributions can be made depending on profits. The aggregate benefit payable to an employee is dependent upon his rate of contribution, the earnings of the fund, and the length of time such employee continues as a participant. The Company has recognized expenses of approximately $1,243,000, $1,260,000 and $1,765,000 under the plans for fiscal 2010, 2009 and 2008, respectively. The Company also contributed to a similar plan through EWST whereby the Company matches employee elective contributions up to a maximum of 5% of compensation. Expenses recognized for fiscal 2010, 2009 and 2008 for the EWST plan were approximately $104,000, $94,000 and $86,000, respectively.

The Company's Israeli subsidiaries provide for employee severance liabilities pursuant to the Israeli severance pay law and labor agreements. The Company's liability is fully provided for by monthly payments deposited with insurers and by a reserve established by the Company to cover the portion of this liability not covered by the Company's deposits. In addition to recognizing an expense for the funding to the insurance programs for this severance obligation, the Company also records as expense the net increase in its unfunded severance liability. The liability for this unfunded severance obligation is included in "Other long-term liabilities" in the Consolidated Balance Sheets and was $2,041,000 and $2,231,000 for fiscal 2010 and 2009, respectively. The total expense recognized for employee severance programs in Israel (both the funded and unfunded portion of the program) was approximately $693,000, $1,055,000, and $458,000 for fiscal 2010, 2009 and 2008, respectively.

NOTE L — RELATED-PARTY TRANSACTIONS

Prior to the acquisition of MSI, MSI had leased one of its two buildings in Fort Walton Beach, Florida from MSI Investments, a Florida General Partnership. MSI Investments is owned by four individuals, two of whom are currently employees of MSI and one serves as a consultant. Lease costs paid in fiscal 2010, 2009, and 2008 were $299,000, $290,000, and $281,000, respectively.

On August 24, 2005, the Company amended the lease agreements for its manufacturing facility in Farmingdale, New York with a partnership owned by the wife of the Company's current Chairman (and children of the Company's former Chairman) and the children of the Company's former Chief Executive Officer to incorporate two individual leases into a single lease and extended the term of the initial leases to August 31, 2010. The Company incurred rent expense of approximately $430,000, $494,000, and $478,000 in fiscal 2010, 2009 and 2008, respectively, under the leases. During the fourth quarter of fiscal 2008, the Company decided to close its manufacturing facility in Farmingdale, New York and transfer its contracts and assets to its other facilities in Whippany, New Jersey, Woburn, Massachusetts, Lancaster, Pennsylvania and Jerusalem, Israel. On January 25, 2009, the Company entered into a modification of the lease to reduce the amount of space it was leasing and reduce the annual rental payments remaining under the lease to approximately $430,000 annually through August 2010.

The Company entered into a new three year lease agreement commencing September 1, 2010 with a partnership owned by the wife of the Company's current Chairman (and children of the Company's former Chairman) relocating its Farmingdale, New York office to a new location having approximately 4,000 square feet at an annual cost of $72,000, subject to escalation of 3% per annum.

Employee stock options for 1,676,700, 3,190,800 and 3,512,225 shares were not considered in the computation of diluted earnings (loss) per share calculations for fiscal 2010, 2009 and 2008, respectively, as their effect is anti-dilutive. The number of stock options not included in the computation of diluted EPS for fiscal year 2010 relates to stock options having exercise prices which are greater than the average market price of the common shares during the period, and therefore, are anti-dilutive. The options, which were outstanding as of August 1, 2010, expire at various dates through June 8, 2017 (See Note O).

NOTE P — SIGNIFICANT SEGMENTS, MAJOR CUSTOMERS, EXPORT SALES AND GEOGRAPHIC INFORMATION

The Company's chief operating decision makers are considered to be the Chief Executive Officer/President and the Vice President/Chief Financial Officer ("Chief Executive Officers"). The Company's Chief Executive Officers evaluate both consolidated and disaggregated financial information, primarily gross revenues and cash flows, in deciding how to allocate resources and assess performance. The Chief Executive Officers also use certain disaggregated financial information for the Company's product groups. The Company does not determine a measure of operating income or loss by product group. The Company's product groups have similar long-term economic characteristics, such as application, and are similar in regards to (a) nature of products and production processes, (b) type of customers and (c) method used to distribute products. Accordingly, the Company operates as a single integrated business and, as such, has one operating segment as a provider of complex microwave technology solutions for the defense, aerospace and medical industries worldwide. All of the Company's revenues result from sales of its products.

Net sales for fiscal 2010, 2009 and 2008 were as follows: defense electronics, $179,035,000, $150,916,000 and $125,873,000, respectively; and commercial technologies, $9,088,000, $9,173,000 and $10,215,000, respectively.

Approximately 62%, 61% and 62% of our net sales for fiscal 2010, 2009 and 2008, respectively, were made to United States government agencies and their contractors and subcontractors for defense programs. Net sales directly to the U.S. Government in fiscal 2010, 2009, and 2008 accounted for approximately 15%, 12%, and 14% of net sales, respectively. Lockheed Martin Corporation and Northrop Grumman Corporation accounted for approximately 13% and 20% of net sales, respectively, in fiscal 2010 and accounted for 13% and 16% of net sales, respectively, in fiscal 2009. No other customer accounted for 10% or more of consolidated net sales during the periods presented. Sales to foreign customers amounted to approximately $64,251,000 (34%), $52,548,000 (33%), and $45,193,000 (33%) in fiscal 2010, 2009 and 2008, respectively.

The increases are primarily attributable to the acquisition of Eyal.

NOTE Q — DERIVATIVE FINANCIAL INSTRUMENTS

In October 2001, the Company entered into an interest rate swap with a bank pursuant to which it exchanged floating rate interest in connection with the Bonds discussed in Note H on a notional amount of $3,000,000 for a fixed rate of 4.07% for a ten-year period ending October 1, 2011. The notional amount reduces each year in tandem with the annual installments due on the Bonds. The fixing of the interest rate for the ten year period offsets the Company's exposure to the uncertainty of floating interest rates on the Bonds, and as such has been designated as a cash flow hedge. The hedge is deemed to be highly effective and any ineffectiveness will be recognized in interest expense in the reporting period. The fair value of the

NOTE Q — DERIVATIVE FINANCIAL INSTRUMENTS (Continued)

interest rate swap was a liability of $85,200 and $125,000 as of August 1, 2010 and August 2, 2009, respectively. There was no material hedge ineffectiveness related to cash flow hedges during the period to be recognized in earnings. There was no gain or loss reclassified from accumulated other comprehensive income into earnings during the fiscal year ended August 1, 2010 as a result of the discontinuance of a cash flow hedge due to the probability of the original forecasted transaction not occurring.

NOTE R — FAIR VALUES OF FINANCIAL INSTRUMENTS

Financial assets and liabilities carried at fair value are classified and disclosed in one of the following three categories:

Level 1 — Observable inputs such as quoted prices in active markets.

Level 2 — Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly.

Level 3 — Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the assignment of an asset or liability within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

The following methods and assumptions were used by the Company in estimating its fair value disclosures for financial instruments:

Cash and cash equivalents:    The carrying amount reported in the Consolidated Balance Sheet for cash and cash equivalents approximates fair value because of the short-term maturity of those instruments.

Accounts receivable and accounts payable:    The carrying amounts reported in the Consolidated Balance Sheet for trade accounts receivable and accounts payable approximates fair value because of the short-term maturity of those instruments.

Long-term debt:    The carrying amount reported in the Consolidated Balance Sheet for the mortgage note, industrial revenue bonds (including the related interest rate swap) and term loan approximate fair value based on the variable interest rates related to the debt.

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with instructions to Form 10-Q and Article 10 of Regulation S-X and do not include all of the information and disclosures normally included in annual financial statements as required by accounting principles generally accepted in the United States of America ("U.S. GAAP") for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included in the accompanying Condensed Consolidated Financial Statements. Operating results for this quarter are not necessarily indicative of the results of operations that may be expected for any other interim period or for the full fiscal year. These statements should be read in conjunction with the consolidated financial statements and notes thereto, and the Company's description of critical accounting policies included in the Company's 2010 Annual Report on Form 10-K for the fiscal year ended August 1, 2010 as filed with the Securities and Exchange Commission ("SEC") on October 14, 2010. The accounting policies used in preparing these unaudited condensed consolidated interim financial statements are consistent with those described in the August 1, 2010 audited financial statements. The Condensed Consolidated Balance Sheet at August 1, 2010 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. Certain prior-period balances have been reclassified to conform to the current period's financial statement presentation.

The preparation of financial statements in conformity with U.S. GAAP requires that management of the Company make certain estimates and assumptions that affect the reported amounts of assets, liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting periods. These judgments can be subjective and complex, and consequently actual results could differ from those estimates and assumptions. The most significant estimates include: valuation and recoverability of goodwill and long-lived assets; income taxes; recognition of revenue and costs on production contracts; the valuation of inventory; accrual of litigation settlements and other contingencies; and stock-based compensation costs. Each of these areas requires the Company to make use of reasoned estimates including estimating the cost to complete a contract and loss accruals, forecasted cash flows and the net realizable value of its inventory. Changes in estimates can have a material impact on the Company's financial position and results of operations.

4. Income Taxes (Continued)

The provision for income taxes for the thirteen weeks ended October 31, 2010 was $2,067,000 as compared to $1,319,000 for the thirteen weeks ended November 1, 2009. The estimated annual effective tax rate for fiscal 2011, before consideration of discrete items, is approximately 33%. This rate is lower than the statutory U.S. federal tax rate of 35%, primarily due to the Company's foreign earnings attributable to its Israeli and United Kingdom operations which are taxed at estimated rates of 14% and 27%, respectively.

Gross unrecognized tax benefits, excluding interest and penalties, were approximately $5,941,000 at October 31, 2010 of which $363,000 would impact the annual effective tax rate in accordance with deferred tax accounting standards. Management does not anticipate that it is reasonably possible that the amount of unrecognized tax benefits will significantly increase or decrease in the next twelve months.

The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense. The Company recognized $61,000 of accrued interest related to unrecognized tax benefits in the Condensed Consolidated Statement of Income, on a gross basis, for the thirteen weeks ended October 31, 2010; the balance of accrued interest was $277,000 in the Condensed Consolidated Balance Sheet on a gross basis at such date. Both unrecognized tax benefits and the corresponding accrued interest amounts are included as "Other long-term liabilities" in the Condensed Consolidated Balance Sheets.

5. Product Warranties

The Company warrants its products for a period of one year. Product warranty costs are accrued based on historical claims expense, and are included in "Accounts payable and accrued expenses" on the Condensed Consolidated Balance Sheets. The reserve for warranty costs is reduced as warranty repair costs are incurred. The following table presents the change in the accrual for product warranty costs for the thirteen weeks ended October 31, 2010 and November 1, 2009, respectively (in thousands):

6. Litigation

As previously reported, an action was brought against the Company by a competitor in October, 2009. This action alleges that, through the actions of three former employees of the plaintiff, the Company improperly obtained trade secrets to unfairly compete against the plaintiff in seeking and ultimately winning certain contracts with third parties. Micro Systems, Inc., a subsidiary of the Company and the three former employees of the plaintiff, two of whom are current or former employees of Micro Systems, Inc., are also named as defendants in this action. The action alleges misappropriation of trade secrets and seeks

6. Litigation (Continued)

$2,000,000 in compensatory damages, and an unspecified sum in punitive damages and legal fees. The Company has vigorously defended this action and denies any allegation of improperly obtaining and/or misappropriating the plaintiff's trade secrets or proprietary information. Discovery in this case has commenced and the anticipated trial date for the action is May of 2011. The parties are currently in settlement discussions in an effort to attempt to resolve the matter before both sides incur additional significant legal fees and costs. In accordance with ASC 450 related to contingencies, the Company recorded a charge of $1,100,000 during the quarter ended October 31, 2010 which is included in selling and administrative expenses in the accompanying Condensed Consolidated Statement of Income, based on management's assessment that it is probable that a settlement can be reached. However, there is no assurance that a settlement will be reached or, if a settlement is reached, that the charge will represent the amount of the settlement. If a settlement is unable to be reached, the Company anticipates that it will continue to vigorously defend the action.

In July 2010, the Company reached an agreement to settle all securities class actions originally filed in 2006, and subsequently consolidated under the caption: In re Herley Industries, Inc. Securities Litigation, Docket No. 06-CV-2596 (JRS). As previously disclosed, between June 2006 and August 2006, the Company and certain of its current and former officers and directors (the "Individual Defendants") were named as defendants in five related class actions alleging violations of the federal securities laws. Those cases were subsequently consolidated into one class action on behalf of a purported class of all persons who purchased or otherwise acquired shares of our stock during the period October 1, 2001 through June 14, 2006 (the "Class"). At all times during the pendency of the litigation, the Company and the Individual Defendants steadfastly maintained that the claims raised in the securities class action were without merit, and vigorously contested those allegations. As part of the settlement, the Company and the Individual Defendants continue to deny any liability or wrongdoing under the securities laws. The terms of the settlement provided for, in part, the dismissal of the litigation against the Company and all of the Individual Defendants, and the creation by the Company of a $10 million settlement fund. The fund will be allocated, after deduction of court-ordered expenses, such as attorneys' fees and expenses, settlement administration costs and any applicable taxes, among members of the settlement class who submit valid proofs of claim. Upon final approval of the settlement by the Court, in August 2010 the Company paid $10 million out of existing cash reserves to create the settlement fund.

In May, 2010 the Company reached an agreement to settle all stockholder derivative actions originally filed in 2006 in the United States District Court for the Eastern District of Pennsylvania at Docket No. 06-CV-2964 (JRS). The consolidated derivative complaint, filed on January 12, 2007, alleged that current and former directors violated their fiduciary obligations in connection with certain actions or decisions in their capacities as officers or directors of the Company. All of the defendants previously denied any wrongdoing and, under the settlement agreement, the Company and the other defendants continue to deny any breach of fiduciary duties or any other improper actions. Under the terms of the settlement, as approved by the Court, the Company agreed to institute certain corporate governance practices relating to the Board of Directors structure, directors' independence, and nomination and election procedures for directors, related party transactions, director stock ownership, and oversight policies. The Company's Board is committed to the implementation of best practices in the area of corporate governance and believes that the agreed upon practices are consistent with that commitment. In addition, the Court awarded plaintiffs' counsel the sum of $975,000 for fees and costs in pursuit of the consolidated derivative action. The Company paid this award in August 2010.

6. Litigation (Continued)

The Company is involved in various other legal proceedings and claims which arise in the ordinary course of its business. While any litigation contains an element of uncertainty, management believes that the outcome of such other litigation will not have a material adverse effect on the Company's financial position or results of operations.

7. Line of Credit, Long-Term Debt and Stand-by Letters of Credit

We have a $40,000,000 Revolving Credit Loan Agreement ("Agreement") with two banks on an unsecured basis, which may be used for general corporate purposes, including business acquisitions and stand-by letters of credit. The Agreement requires the payment of interest only on a monthly basis and payment of the outstanding principal balance on March 31, 2012. The Company may elect to borrow with interest at (A) the bank's prime rate of interest minus 0.50% or (B) the greater of (i) LIBOR plus a margin of 2.50% or (ii) 3.50%. There is a fee of 25 basis points per annum on the unused portion of the credit facility payable quarterly and a fee of 1.50% per annum on outstanding stand-by letters of credit. The Agreement contains various financial covenants, including minimum tangible net worth, total liabilities to tangible net worth, debt service coverage and restrictions on other borrowings. The Company was in compliance with all of its financial covenants at October 31, 2010.

We had no loans outstanding under our credit facility during the quarter ended October 31, 2010. Stand-by letters of credit in the amount of approximately $6,583,000, of which $4,589,000 reduces the amount of credit available under the credit line, were outstanding at October 31, 2010. We had approximately $35,411,000 available under our line at October 31, 2010.

On September 16, 2008, the Company entered into a ten-year term loan with a bank in Israel in the amount of $10,000,000 in connection with the acquisition of Eyal. The loan is payable in quarterly installments of $250,000 plus interest at LIBOR plus a margin of 1.5%. The loan agreement contains various financial covenants which have been met at October 31, 2010, including minimum net equity, as defined.

8. Stock Buyback Program

In October 2007, the Company's Board of Directors approved an expansion of its existing stock buyback program to make additional purchases of up to 1,000,000 shares of its common stock in the open market or in private transactions, in accordance with applicable SEC rules for an aggregate of 3,000,000 shares. As of August 1, 2010, the Company had repurchased and retired approximately 2,460,000 shares under the program. There were no stock repurchases during the thirteen weeks ended October 31, 2010. During the thirteen weeks ended November 1, 2009, the Company repurchased and retired 35,902 shares of its common stock pursuant to this program at an aggregate cost of approximately $441,000. Funds to acquire the shares came from excess cash reserves. The timing, actual number and value of any additional shares that may be repurchased under this program will depend on a number of factors, including the Company's future financial performance, the Company's available cash resources and competing uses for the cash, prevailing market prices of the Company's common stock and the number of shares that become available for sale at prices that the Company believes are attractive. As of October 31, 2010, approximately 540,000 shares were eligible for future purchase under the Company's buyback program.

14. New Accounting Pronouncements

Newly issued effective accounting pronouncements:

In April 2010, the Financial Accounting Standards Board issued ASU 2010-17, "Revenue Recognition — Milestone Method." The amended guidance provides the criteria that should be met for determining whether the milestone method of revenue recognition is appropriate for research and development transactions. The amended guidance is currently effective for milestones achieved in the Company's fiscal period ended October 31, 2010 and did not have any impact on the Company's financial position, results of operations, or cash flows.

In October 2009, the Financial Accounting Standards Board issued ASU 2009-13, "Multiple Deliverable Revenue Arrangements." This amended guidance enables companies to account for products or services (deliverables) separately rather than as a combined unit in certain circumstances. The amended guidance is currently effective for revenue arrangements entered into or materially modified in the Company's fiscal period ended October 31, 2010 and did not have a significant impact on the Company's financial position, results of operations, or cash flows.

Other new accounting pronouncements issued but not currently effective are not expected to have a significant effect on the Company's financial position, results of operations, or cash flows.

15. Related Party Transaction

Prior to the acquisition of MSI, MSI had leased one of its two buildings in Fort Walton Beach, Florida from MSI Investments, a Florida LLC. Owners of MSI Investments include two current employees of MSI and one who serves as a consultant. Lease expense was approximately $74,000 for the thirteen weeks ended October 31, 2010 and November 1, 2009, respectively.

On August 24, 2005, the Company amended the lease agreements for its manufacturing facility in Farmingdale, New York with a partnership owned by the wife of the Company's current Chairman (and children of the Company's former Chairman) and the children of the Company's former Chief Executive Officer to incorporate two individual leases into a single lease and extended the term of the initial leases to August 31, 2010. The Company incurred rent expense of approximately $430,000, $494,000, and $478,000 in fiscal 2010, 2009 and 2008, respectively, under the leases. During the fourth quarter of fiscal 2008, the Company decided to close its manufacturing facility in Farmingdale, New York and transfer its contracts and assets to its other facilities in Whippany, New Jersey; Woburn, Massachusetts; Lancaster, Pennsylvania and Jerusalem, Israel. On January 25, 2009, the Company entered into a modification of the lease to reduce the amount of space it was leasing and reduce the annual rental payments remaining under the lease to approximately $430,000 annually through August 2010.

The Company entered into a new three year lease agreement commencing September 1, 2010 with a partnership owned by the wife of the Company's current Chairman (and children of the Company's former Chairman) relocating its Farmingdale, New York office to a new location having approximately 4,000 square feet at an annual cost of $72,000, subject to escalation of 3% per annum.

This prospectus provides you with a general description of the securities we may offer. Each time we offer a type or series of securities under this prospectus, we will provide a prospectus supplement that will describe the specific amounts, prices and other important terms of the securities, including, to the extent applicable:

        The prospectus supplement and any related free writing prospectus that we may authorize to be provided to you may also add or update information contained in this prospectus or in documents we have incorporated by reference. However, no prospectus supplement or free writing prospectus will offer a security that is not registered and described in this prospectus at the time of the effectiveness of the registration statement of which this prospectus is a part.

THIS PROSPECTUS MAY NOT BE USED TO CONSUMMATE A SALE OF SECURITIES UNLESS IT IS ACCOMPANIED BY A PROSPECTUS SUPPLEMENT.

        We may sell the securities directly to investors or to or through agents, underwriters or dealers. We, and our agents or underwriters, reserve the right to accept or reject all or part of any proposed purchase of securities. If we do offer securities to or through agents or underwriters, we will include in the applicable prospectus supplement:

•

the names of those agents or underwriters;



•

applicable fees, discounts and commissions to be paid to them;



•

details regarding over-allotment options, if any; and



•

        Common Stock.    We may issue shares of our common stock from time to time. The holders of common stock are entitled to one vote for each share held of record on all matters submitted to a vote of stockholders and do not have cumulative voting rights. Subject to preferences that may be applicable to any outstanding shares of preferred stock, the holders of common stock are entitled to receive ratably only those dividends as may be declared by our board of directors out of legally available funds. Upon our liquidation, dissolution or winding up, holders of our common stock are entitled to share

4

---

ratably in all assets remaining after payment of liabilities and the liquidation preferences of any outstanding shares of preferred stock.

        Preferred Stock.    We may issue shares of our preferred stock from time to time, in one or more series. Under our amended and restated certificate of incorporation, our board of directors has the authority, without further action by stockholders, to designate up to 5,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges, qualifications and restrictions granted to or imposed upon the preferred stock, including dividend rights, conversion rights, voting rights, rights and terms of redemption, liquidation preference and sinking fund terms, any or all of which may be greater than the rights of the common stock.

        If we sell any series of preferred stock under this prospectus, we will fix the designations, powers, preferences and rights of such series of preferred stock, as well as the qualifications, limitations or restrictions thereon, in the certificate of designation relating to that series. We will file as an exhibit to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of any certificate of designation that describes the terms of the series of preferred stock we are offering before the issuance of the related series of preferred stock. We urge you to read the applicable prospectus supplement (and any free writing prospectus that we may authorize to be provided to you) related to the series of preferred stock being offered, as well as the complete certificate of designation that contains the terms of the applicable series of preferred stock.

        Debt Securities.    We may issue debt securities from time to time, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. The senior debt securities will rank equally with any other unsecured and unsubordinated debt. The subordinated debt securities will be subordinate and junior in right of payment, to the extent and in the manner described in the instrument governing the debt, to all of our senior indebtedness. Convertible debt securities will be convertible into or exchangeable for our common stock or our other securities. Conversion may be mandatory or at your option and would be at prescribed conversion rates.

        The debt securities will be issued under one or more indentures, which are contracts between us and a national banking association or other eligible party, as trustee. In this prospectus, we have summarized certain general features of the debt securities. We urge you, however, to read the applicable prospectus supplement (and any free writing prospectus that we may authorize to be provided to you) related to the series of debt securities being offered, as well as the complete indentures that contain the terms of the debt securities. Forms of indentures have been filed as exhibits to the registration statement of which this prospectus is a part, and supplemental indentures and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this prospectus is a part or will be incorporated by reference from reports that we file with the SEC.

        Warrants.    We may issue warrants for the purchase of common stock, preferred stock and/or debt securities in one or more series. We may issue warrants independently or together with common stock, preferred stock and/or debt securities, and the warrants may be attached to or separate from these securities. In this prospectus, we have summarized certain general features of the warrants. We urge you, however, to read the applicable prospectus supplement (and any free writing prospectus that we may authorize to be provided to you) related to the particular series of warrants being offered, as well as the complete warrant agreements and warrant certificates that contain the terms of the warrants. We will file as an exhibit to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, forms of the warrant agreements and forms of warrant certificates containing the terms of the warrants being offered.

5

        We will evidence each series of warrants by warrant certificates that we will issue. Warrants may be issued under an applicable warrant agreement that we enter into with a warrant agent. We will indicate the name and address of the warrant agent, if applicable, in the prospectus supplement relating to the particular series of warrants being offered.

        Units.    We may issue, in one or more series, units consisting of common stock, preferred stock, debt securities and/or warrants for the purchase of common stock, preferred stock and/or debt securities in any combination. In this prospectus, we have summarized certain general features of the units. We urge you, however, to read the applicable prospectus supplement (and any free writing prospectus that we may authorize to be provided to you) related to the series of units being offered, as well as the complete unit agreement that contains the terms of the units. We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of unit agreement and any supplemental agreements that describe the terms of the series of units we are offering before the issuance of the related series of units.

        We will evidence each series of units by unit certificates that we will issue. Units may be issued under a unit agreement that we enter into with a unit agent. We will indicate the name and address of the unit agent, if applicable, in the prospectus supplement relating to the particular series of units being offered.

RATIO OF EARNINGS TO FIXED CHARGES

        The following summary is qualified by the more detailed information appearing in the computation table found in Exhibit 12.1 to the registration statement of which this prospectus is part and the historical financial statements, including the notes to those financial statements, incorporated by reference in this prospectus.

        Our earnings are inadequate to cover fixed charges. The following table sets forth the dollar amount of the coverage deficiency for all periods. We have not included a ratio of earnings to combined fixed charges and preferred stock dividends because no preferred dividends are accrued, accruing or payable on our outstanding preference shares.

USE OF PROCEEDS

        Except as described in any prospectus supplement or in any related free writing prospectus that we may authorize to be provided to you, we currently intend to use the net proceeds from the sale of the securities offered hereby for general corporate purposes, including, among other things, working capital requirements and potential re-payment of indebtedness that may be outstanding at the time of any offering under this prospectus. We may also use a portion of the net proceeds to acquire or invest in businesses, services and technologies that are complementary to our own. Pending these uses, we expect to invest the net proceeds in short-term, investment-grade securities.

DESCRIPTION OF CAPITAL STOCK

Authorized and Outstanding Capital Stock

        Our authorized capital stock consists of 195,000,000 shares of common stock, par value $0.001 per share, and 5,000,000 shares of preferred stock, par value $0.001 per share, issuable in one or more series designated by Kratos' board of directors, of which 63,637 shares have been designated Series A Preferred Stock, 90,000 shares have been designated Series B Preferred Stock and 1,200,000 have been designated Series C Preferred Stock. As of August 12, 2009, there were 130,262,590 shares of common stock, no shares of Series A Preferred Stock, 10,000 shares of Series B Preferred Stock and no shares of Series C Preferred Stock outstanding.

Common Stock

        The holders of our common stock have one vote per share. Holders of common stock are not entitled to vote cumulatively for the election of directors. Generally, all matters to be voted on by stockholders must be approved by a majority, or, in the case of election of directors, by a plurality, of the votes cast at a meeting at which a quorum is present, voting together as a single class, subject to any voting rights granted to holders of any then outstanding preferred stock. Shares of common stock are entitled to participate equally in dividends when and as dividends may be declared by our board of directors out of funds legally available for the payment of dividends. In the event of our voluntary or involuntary liquidation, dissolution or winding up, the prior rights of our creditors and the liquidation preference of any preferred stock then outstanding must first be satisfied. The holders of common stock will be entitled to share in the remaining assets on a pro rata basis. No shares of common stock are subject to redemption or have redemptive rights to purchase additional shares of common stock.

        Our common stock is listed on the Nasdaq Global Select Market under the symbol "KTOS".

Preferred Stock

        Our certificate of incorporation provides that we may issue shares of preferred stock from time to time in one or more series. Our board of directors is authorized to fix the voting rights, if any, designations, powers, preferences, qualifications, limitations and restrictions thereof, applicable to the shares of each series. The board of directors may, without stockholder approval issue preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the common stock and could have anti-takeover effects, including preferred stock or rights to acquire preferred stock in connection with implementing a shareholder rights plan. The ability of the board of directors to issue preferred stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control or the removal of its existing management.

Series A Preferred Stock

        There are currently no shares of Series A Preferred Stock issued and outstanding.

Series B Preferred Stock

        On May 30, 2002, we issued an aggregate of 90,000 shares of Series B Preferred Stock, 10,000 shares of which were outstanding on August 4, 2009. Each share of Series B Preferred Stock is currently convertible into 100 shares of common stock and will automatically convert into common stock if and when our common stock trades at or above $11.00 per share for 30 consecutive trading days after that date. Upon any voluntary or involuntary liquidation, dissolution or winding up of our affairs, before any payment is to be made to the holders of common stock, the holders of Series B Preferred Stock are entitled to receive $500 per share plus all accumulated or accrued and unpaid dividends for such share. Holders of shares of Series B Preferred Stock are entitled to vote on all

7

---

matters submitted to a vote of the holders of shares of common stock, including with respect to the election of members of the board of directors, on an as-converted to common stock basis.

Series C Preferred Stock

        On December 16, 2004, in connection with the approval of our Stockholder Rights Plan, our board of directors authorized and declared a dividend of one right to purchase on one-hundredth of a share of Series C Preferred Stock for each outstanding share of common stock to stockholders of record as of the close of business December 27, 2004. Each right entitles the registered holder, subject to the terms of the Stockholder Rights Plan, to purchase one one-hundredth of a share of Series C Preferred at a purchase price of $54.00, subject to adjustment. The rights are not exercisable until a Distribution Date occurs (as that term is defined in the Stockholder Rights Plan) and will expire at the close of business on the tenth anniversary of the Stockholder Rights Plan unless earlier redeemed or exchanged. There are currently no shares of Series C Preferred Stock issued and outstanding.

Anti-Takeover Provisions

        The provisions of the Delaware General Corporation Law, or DGCL, our amended and restated certificate of incorporation, amended and restated bylaws and our Stockholder Rights Plan contain provisions that could discourage or make more difficult a change in control of the Company, including an acquisition of the Company by means of a tender offer, a proxy contest and removal of our incumbent officers and directors, without the support of our board of directors. A summary of these provisions follows.

Statutory Business Combination Provision

        We are subject to Section 203 of the DGCL, which, subject to certain exceptions, prohibits a Delaware corporation from engaging in any "business combination" with an "interested stockholder" for a period of three years following the time that such stockholder became an interested stockholder, unless:

•

the board of directors of the corporation approves either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder, prior to the time the interested stockholder attained that status;



•

upon the closing of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding those shares owned by persons who are directors and also officers and by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or



•

at or subsequent to such time, the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least two-thirds of the outstanding voting stock that is not owned by the interested stockholder.

        With certain exceptions, an "interested stockholder" is a person or group who or which owns 15% or more of the corporation's outstanding voting stock (including any rights to acquire stock pursuant to an option, warrant, agreement, arrangement or understanding, or upon the exercise of conversion or exchange rights, and stock with respect to which the person has voting rights only), or is an affiliate or associate of the corporation and was the owner of 15% or more of such voting stock at any time within the previous three years.

8

---

        In general, Section 203 defines a business combination to include:

•

any merger or consolidation involving the corporation and the interested stockholder;



•

any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder;



•

subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;



•

any transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation beneficially owned by the interested stockholder; or



•

the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.

        A Delaware corporation may "opt out" of this provision with an express provision in its original certificate of incorporation or an express provision in its amended and restated certificate of incorporation or bylaws resulting from a stockholders' amendment approved by at least a majority of the outstanding voting shares. However, Kratos has not "opted out" of this provision. Section 203 could prohibit or delay mergers or other takeover or change-in-control attempts and, accordingly, may discourage attempts to acquire Kratos.

Stockholder Rights Plan

        We have a stockholder rights plan that may discourage certain types of transactions involving an actual or potential change in control and may limit our stockholders' ability to approve transactions that they deem to be in their best interests.

Election and Removal of Directors

        Our board of directors is elected annually by all holders of our capital stock. Directors may be removed without cause by the affirmative vote of the holders of at least a majority of the outstanding shares entitled to vote on such removal; provided however, that unless the entire board is removed, no individual director may be removed when the votes cast against such director's removal, or not consenting in writing to such removal, would be sufficient to elect that director if voted cumulatively at an election in which the same total number of votes were cast (or if such action is taken by written consent, all shares entitled to vote were voted) and the entire number of directors authorized at the time of such directors most recent election were then being elected.

No Stockholder Action by Written Consent

        Our certificate of incorporation provides that any action required or permitted to be taken by the holders of common stock at an annual or special meeting of stockholders must be effected at a duly called meeting and may not be taken or effected by written consent of the stockholders.

Stockholder Meetings

        Under our amended and restated bylaws, only the chairman of the board of directors, the chief executive officer or a majority of the total number of authorized directors may call a special meeting of the stockholders, and any business conducted at any special meeting will be limited to the purpose or purposes specified in the order calling for the special meeting.

Requirements for Advance Notification of Stockholder Nominations and Proposals

        In order for our stockholders to properly bring nominations or business before an annual meeting, they must comply with certain notice requirements as provided by our amended and restated bylaws. Typically, in order for such notices to be timely, they must be provided to us not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting. For such notices to be timely in the event the annual meeting is advanced more than 30 days prior to or delayed by more than 30 days after the anniversary of the preceding year's annual meeting, notice must be provided to us not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting or the 10th day following the day on which public announcement of the date of such meeting is first made.

Amendment of Charter Provisions

        The affirmative vote of the holders of at least 66-2/3% of the voting power of all of the then-outstanding shares of our voting stock, voting together as a single class, is required to, among other things, alter, amend or repeal certain provisions of our amended and restated certificate of incorporation, including those related to the election and removal of the board of directors, amendment of our bylaws and certificate of incorporation, restrictions against stockholder actions by written consent and the indemnification of officers and directors.

        Our amended and restated bylaws may only be amended (or new bylaws adopted) by the board of directors or the affirmative vote of the holders of at least 66-2/3% of the voting power of all of the then-outstanding shares of our voting stock.

Transfer Agent and Registrar

        The transfer agent and registrar for our common stock is Wells Fargo Bank, N.A., Shareowner Services. Its address is 161 North Concord Exchange Street, South Saint Paul, MN, 55075 and its telephone number is (800) 468-9716. The transfer agent for any series of preferred stock that we may offer under this prospectus will be named and described in the prospectus supplement for that series.

DESCRIPTION OF DEBT SECURITIES

        We may issue debt securities, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. While the terms we have summarized below will apply generally to any debt securities that we may offer under this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in the applicable prospectus supplement. The terms of any debt securities offered under a prospectus supplement may differ from the terms described below. Unless the context requires otherwise, whenever we refer to the indentures, we also are referring to any supplemental indentures that specify the terms of a particular series of debt securities.

        We will issue the senior debt securities under the senior indenture that we will enter into with the trustee named in the senior indenture. We will issue the subordinated debt securities under the subordinated indenture that we will enter into with the trustee named in the subordinated indenture. The indentures will be qualified under the Trust Indenture Act of 1939. We use the term "debenture trustee" to refer to either the trustee under the senior indenture or the trustee under the subordinated indenture, as applicable. We have filed forms of indentures to the registration statement of which this prospectus is a part, and supplemental indentures and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this prospectus is a part or will be incorporated by reference from reports that we file with the SEC.

Consolidation, Merger or Sale

        Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the indentures will not contain any covenant that restricts our ability to merge or consolidate, or sell, convey, transfer or otherwise dispose of all or substantially all of our assets. However, any successor to or acquirer of such assets must assume all of our obligations under the indentures or the debt securities, as appropriate. If the debt securities are convertible into or exchangeable for our other securities or securities of other entities, the person with whom we consolidate or merge or to whom we sell all of our property must make provisions for the conversion of the debt securities into securities that the holders of the debt securities would have received if they had converted the debt securities before the consolidation, merger or sale.

Events of Default Under the Indenture

        Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the following are events of default under the indentures with respect to any series of debt securities that we may issue:

•

if we fail to pay interest when due and payable and our failure continues for 90 days and the time for payment has not been extended or deferred;



•

if we fail to pay the principal, premium or sinking fund payment, if any, when due and payable and the time for payment has not been extended or delayed;



•

if we fail to observe or perform any other covenant contained in the debt securities or the indentures, other than a covenant specifically relating to another series of debt securities, and our failure continues for 90 days after we receive notice from the debenture trustee or holders of at least 25% in aggregate principal amount of the outstanding debt securities of the applicable series; and



•

if specified events of bankruptcy, insolvency or reorganization occur.

        If an event of default with respect to debt securities of any series occurs and is continuing, other than an event of default specified in the last bullet point above, the debenture trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series, by notice to us in writing, and to the debenture trustee if notice is given by such holders, may declare the unpaid principal of, premium, if any, and accrued interest, if any, due and payable immediately. If an event of default specified in the last bullet point above occurs with respect to us, the principal amount of and accrued interest, if any, of each issue of debt securities then outstanding shall be due and payable without any notice or other action on the part of the debenture trustee or any holder.

        The holders of a majority in principal amount of the outstanding debt securities of an affected series may waive any default or event of default with respect to the series and its consequences, except defaults or events of default regarding payment of principal, premium, if any, or interest, unless we have cured the default or event of default in accordance with the indenture. Any waiver shall cure the default or event of default.

        Subject to the terms of the indentures, if an event of default under an indenture shall occur and be continuing, the debenture trustee will be under no obligation to exercise any of its rights or powers under such indenture at the request or direction of any of the holders of the applicable series of debt securities, unless such holders have offered the debenture trustee reasonable indemnity. The holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the

13

---

debenture trustee, or exercising any trust or power conferred on the debenture trustee, with respect to the debt securities of that series, provided that:

•

the direction so given by the holder is not in conflict with any law or the applicable indenture; and



•

subject to its duties under the Trust Indenture Act of 1939, the debenture trustee need not take any action that might involve it in personal liability or might be unduly prejudicial to the holders not involved in the proceeding.

        A holder of the debt securities of any series will have the right to institute a proceeding under the indentures or to appoint a receiver or trustee, or to seek other remedies only if:

•

the holder has given written notice to the debenture trustee of a continuing event of default with respect to that series;



•

the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have made written request, and such holders have offered reasonable indemnity to the debenture trustee to institute the proceeding as trustee; and



•

the debenture trustee does not institute the proceeding, and does not receive from the holders of a majority in aggregate principal amount of the outstanding debt securities of that series other conflicting directions within 90 days after the notice, request and offer.

        These limitations do not apply to a suit instituted by a holder of debt securities if we default in the payment of the principal, premium, if any, or interest on, the debt securities.

        We will periodically file statements with the debenture trustee regarding our compliance with specified covenants in the indentures.

Modification of Indenture; Waiver

        We and the debenture trustee may change an indenture without the consent of any holders with respect to specific matters:

•

to fix any ambiguity, defect or inconsistency in the indenture;



•

        In addition, under the indentures, the rights of holders of a series of debt securities may be changed by us and the debenture trustee with the written consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each series that is affected. However, unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, we and the debenture trustee may make the following changes only with the consent of each holder of any outstanding debt securities affected:

•

reducing the principal amount, reducing the rate of or extending the time of payment of interest, or reducing any premium payable upon the redemption of any debt securities; or



•

Discharge

        Each indenture provides that we can elect to be discharged from our obligations with respect to one or more series of debt securities, except for specified obligations, including obligations to:

•

register the transfer or exchange of debt securities of the series;

appoint any successor trustee.

        In order to exercise our rights to be discharged, we must deposit with the debenture trustee money or government obligations sufficient to pay all the principal of, any premium, if any, and interest on, the debt securities of the series on the dates payments are due.

Form, Exchange and Transfer

        We will issue the debt securities of each series only in fully registered form without coupons and, unless we provide otherwise in the applicable prospectus supplement, in denominations of $1,000 and any integral multiple thereof. The indentures provide that we may issue debt securities of a series in temporary or permanent global form and as book-entry securities that will be deposited with, or on behalf of, The Depository Trust Company or another depositary named by us and identified in a prospectus supplement with respect to that series. See "Legal Ownership of Securities" for a further description of the terms relating to any book-entry securities.

        At the option of the holder, subject to the terms of the indentures and the limitations applicable to global securities described in the applicable prospectus supplement, the holder of the debt securities of

15

---

any series can exchange the debt securities for other debt securities of the same series, in any authorized denomination and of like tenor and aggregate principal amount.

        Subject to the terms of the indentures and the limitations applicable to global securities set forth in the applicable prospectus supplement, holders of the debt securities may present the debt securities for exchange or for registration of transfer, duly endorsed or with the form of transfer endorsed thereon duly executed if so required by us or the security registrar, at the office of the security registrar or at the office of any transfer agent designated by us for this purpose. Unless otherwise provided in the debt securities that the holder presents for transfer or exchange, we will impose no service charge for any registration of transfer or exchange, but we may require payment of any taxes or other governmental charges.

        We will name in the applicable prospectus supplement the security registrar, and any transfer agent in addition to the security registrar, that we initially designate for any debt securities. We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the debt securities of each series.

        If we elect to redeem the debt securities of any series, we will not be required to:

•

issue, register the transfer of, or exchange any debt securities of that series during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of any debt securities that may be selected for redemption and ending at the close of business on the day of the mailing; or



•

register the transfer of or exchange any debt securities so selected for redemption, in whole or in part, except the unredeemed portion of any debt securities we are redeeming in part.

Information Concerning the Debenture Trustee

        The debenture trustee, other than during the occurrence and continuance of an event of default under an indenture, undertakes to perform only those duties as are specifically set forth in the applicable indenture. Upon an event of default under an indenture, the debenture trustee must use the same degree of care as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to this provision, the debenture trustee is under no obligation to exercise any of the powers given it by the indentures at the request of any holder of debt securities unless it is offered reasonable security and indemnity against the costs, expenses and liabilities that it might incur.

Payment and Paying Agents

        Unless we otherwise indicate in the applicable prospectus supplement, we will make payment of the interest on any debt securities on any interest payment date to the person in whose name the debt securities, or one or more predecessor securities, are registered at the close of business on the regular record date for the interest.

        We will pay principal of and any premium and interest on the debt securities of a particular series at the office of the paying agents designated by us, except that unless we otherwise indicate in the applicable prospectus supplement, we will make interest payments by check that we will mail to the holder or by wire transfer to certain holders. Unless we otherwise indicate in the applicable prospectus supplement, we will designate the corporate trust office of the debenture trustee in the City of New York as our sole paying agent for payments with respect to debt securities of each series. We will name in the applicable prospectus supplement any other paying agents that we initially designate for the debt securities of a particular series. We will maintain a paying agent in each place of payment for the debt securities of a particular series.

16

---

        All money we pay to a paying agent or the debenture trustee for the payment of the principal of or any premium or interest on any debt securities that remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the holder of the debt security thereafter may look only to us for payment thereof.

Governing Law

        The indentures and the debt securities will be governed by and construed in accordance with the laws of the State of New York, except to the extent that the Trust Indenture Act of 1939 is applicable.

Subordination of Subordinated Debt Securities

        The subordinated debt securities will be unsecured and will be subordinate and junior in priority of payment to certain of our other indebtedness to the extent described in a prospectus supplement. The subordinated indenture does not limit the amount of subordinated debt securities that we may issue, nor does it limit us from issuing any other secured or unsecured debt.

DESCRIPTION OF WARRANTS

        We may issue warrants for the purchase of common stock, preferred stock and/or debt securities in one or more series. We may issue warrants independently or together with common stock, preferred stock and/or debt securities, and the warrants may be attached to or separate from these securities. While the terms summarized below will apply generally to any warrants that we may offer, we will describe the particular terms of any series of warrants in more detail in the applicable prospectus supplement. The terms of any warrants offered under a prospectus supplement may differ from the terms described below.

        We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of warrant agreement, including a form of warrant certificate, that describes the terms of the particular series of warrants we are offering before the issuance of the related series of warrants. The following summaries of material provisions of the warrants and the warrant agreements are subject to, and qualified in their entirety by reference to, all the provisions of the warrant agreement and warrant certificate applicable to the particular series of warrants that we may offer under this prospectus. We urge you to read the applicable prospectus supplements related to the particular series of warrants that we may offer under this prospectus, as well as any related free writing prospectuses, and the complete warrant agreements and warrant certificates that contain the terms of the warrants.

General

        We will describe in the applicable prospectus supplement the terms of the series of warrants being offered, including:

•

the offering price and aggregate number of warrants offered;



•

the currency for which the warrants may be purchased;



•

if applicable, the designation and terms of the securities with which the warrants are issued and the number of warrants issued with each such security or each principal amount of such security;



•

if applicable, the date on and after which the warrants and the related securities will be separately transferable;



•

in the case of warrants to purchase debt securities, the principal amount of debt securities purchasable upon exercise of one warrant and the price at, and currency in which, this principal amount of debt securities may be purchased upon such exercise;

17

---

•

in the case of warrants to purchase common stock or preferred stock, the number of shares of common stock or preferred stock, as the case may be, purchasable upon the exercise of one warrant and the price at which these shares may be purchased upon such exercise;



•

the effect of any merger, consolidation, sale or other disposition of our business on the warrant agreements and the warrants;



•

the terms of any rights to redeem or call the warrants;



•

any provisions for changes to or adjustments in the exercise price or number of securities issuable upon exercise of the warrants;



•

the dates on which the right to exercise the warrants will commence and expire;



•

the manner in which the warrant agreements and warrants may be modified;



•

a discussion of any material or special United States federal income tax consequences of holding or exercising the warrants;



•

the terms of the securities issuable upon exercise of the warrants; and



•

any other specific terms, preferences, rights or limitations of or restrictions on the warrants.

        Before exercising their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon such exercise, including:

•

in the case of warrants to purchase debt securities, the right to receive payments of principal of, or premium, if any, or interest on, the debt securities purchasable upon exercise or to enforce covenants in the applicable indenture; or



•

in the case of warrants to purchase common stock or preferred stock, the right to receive dividends, if any, or payments upon our liquidation, dissolution or winding up or to exercise voting rights, if any.

Exercise of Warrants

        Each warrant will entitle the holder to purchase the securities that we specify in the applicable prospectus supplement at the exercise price that we describe in the applicable prospectus supplement. Holders of the warrants may exercise the warrants at any time up to the specified time on the expiration date that we set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

        Holders of the warrants may exercise the warrants by delivering the warrant certificate representing the warrants to be exercised together with specified information, and paying the required amount to the warrant agent in immediately available funds, as provided in the applicable prospectus supplement. We will set forth on the reverse side of the warrant certificate and in the applicable prospectus supplement the information that the holder of the warrant will be required to deliver to the warrant agent.

        Upon receipt of the required payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will issue and deliver the securities purchasable upon such exercise. If fewer than all of the warrants represented by the warrant certificate are exercised, then we will issue a new warrant certificate for the remaining amount of warrants. If we so indicate in the applicable prospectus supplement, holders of the warrants may surrender securities as all or part of the exercise price for warrants.

18

---

Governing Law

        Unless we provide otherwise in the applicable prospectus supplement, the warrants and warrant agreements will be governed by and construed in accordance with the laws of the State of New York.

Enforceability of Rights by Holders of Warrants

        Each warrant agent will act solely as our agent under the applicable warrant agreement and will not assume any obligation or relationship of agency or trust with any holder of any warrant. A single bank or trust company may act as warrant agent for more than one issue of warrants. A warrant agent will have no duty or responsibility in case of any default by us under the applicable warrant agreement or warrant, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a warrant may, without the consent of the related warrant agent or the holder of any other warrant, enforce by appropriate legal action its right to exercise, and receive the securities purchasable upon exercise of, its warrants.

DESCRIPTION OF UNITS

        We may issue, in one more series, units consisting of common stock, preferred stock, debt securities and/or warrants for the purchase of common stock, preferred stock and/or debt securities in any combination. While the terms we have summarized below will apply generally to any units that we may offer under this prospectus, we will describe the particular terms of any series of units in more detail in the applicable prospectus supplement. The terms of any units offered under a prospectus supplement may differ from the terms described below.

        We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of unit agreement that describes the terms of the series of units we are offering, and any supplemental agreements, before the issuance of the related series of units. The following summaries of material terms and provisions of the units are subject to, and qualified in their entirety by reference to, all the provisions of the unit agreement and any supplemental agreements applicable to a particular series of units. We urge you to read the applicable prospectus supplements related to the particular series of units that we may offer under this prospectus, as well as any related free writing prospectuses and the complete unit agreement and any supplemental agreements that contain the terms of the units.

General

        Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

        We will describe in the applicable prospectus supplement the terms of the series of units being offered, including:

•

the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;



•

any provisions of the governing unit agreement that differ from those described below; and



•

any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units.

        The provisions described in this section, as well as those described under "Description of Capital Stock," "Description of Debt Securities" and "Description of Warrants" will apply to each unit and to any common stock, preferred stock, debt security or warrant included in each unit, respectively.

19

---

Issuance in Series

        We may issue units in such amounts and in such numerous distinct series as we determine.

Enforceability of Rights by Holders of Units

        Each unit agent will act solely as our agent under the applicable unit agreement and will not assume any obligation or relationship of agency or trust with any holder of any unit. A single bank or trust company may act as unit agent for more than one series of units. A unit agent will have no duty or responsibility in case of any default by us under the applicable unit agreement or unit, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a unit may, without the consent of the related unit agent or the holder of any other unit, enforce by appropriate legal action its rights as holder under any security included in the unit.

Title

        We, and any unit agent and any of their agents, may treat the registered holder of any unit certificate as an absolute owner of the units evidenced by that certificate for any purpose and as the person entitled to exercise the rights attaching to the units so requested, despite any notice to the contrary. See "Legal Ownership of Securities" below.

LEGAL OWNERSHIP OF SECURITIES

        We can issue securities in registered form or in the form of one or more global securities. We describe global securities in greater detail below. We refer to those persons who have securities registered in their own names on the books that we or any applicable trustee, depositary or warrant agent maintain for this purpose as the "holders" of those securities. These persons are the legal holders of the securities. We refer to those persons who, indirectly through others, own beneficial interests in securities that are not registered in their own names, as "indirect holders" of those securities. As we discuss below, indirect holders are not legal holders, and investors in securities issued in book-entry form or in street name will be indirect holders.

Book-Entry Holders

        We may issue securities in book-entry form only, as we will specify in the applicable prospectus supplement. This means securities may be represented by one or more global securities registered in the name of a financial institution that holds them as depositary on behalf of other financial institutions that participate in the depositary's book-entry system. These participating institutions, which are referred to as participants, in turn, hold beneficial interests in the securities on behalf of themselves or their customers.

        Only the person in whose name a security is registered is recognized as the holder of that security. Securities issued in global form will be registered in the name of the depositary or its participants. Consequently, for securities issued in global form, we will recognize only the depositary as the holder of the securities, and we will make all payments on the securities to the depositary. The depositary passes along the payments it receives to its participants, which in turn pass the payments along to their customers who are the beneficial owners. The depositary and its participants do so under agreements they have made with one another or with their customers; they are not obligated to do so under the terms of the securities.

        As a result, investors in a book-entry security will not own securities directly. Instead, they will own beneficial interests in a global security, through a bank, broker or other financial institution that participates in the depositary's book-entry system or holds an interest through a participant. As long as

20

---

the securities are issued in global form, investors will be indirect holders, and not holders, of the securities.

Street Name Holders

        We may terminate a global security or issue securities in non-global form. In these cases, investors may choose to hold their securities in their own names or in "street name." Securities held by an investor in street name would be registered in the name of a bank, broker or other financial institution that the investor chooses, and the investor would hold only a beneficial interest in those securities through an account he or she maintains at that institution.

        For securities held in street name, we will recognize only the intermediary banks, brokers and other financial institutions in whose names the securities are registered as the holders of those securities, and we will make all payments on those securities to them. These institutions pass along the payments they receive to their customers who are the beneficial owners, but only because they agree to do so in their customer agreements or because they are legally required to do so. Investors who hold securities in street name will be indirect holders, not holders, of those securities.

Legal Holders

        Our obligations, as well as the obligations of any applicable trustee and of any third parties employed by us or a trustee, run only to the legal holders of the securities. We do not have obligations to investors who hold beneficial interests in global securities, in street name or by any other indirect means. This will be the case whether an investor chooses to be an indirect holder of a security or has no choice because we are issuing the securities only in global form.

        For example, once we make a payment or give a notice to the holder, we have no further responsibility for the payment or notice even if that holder is required, under agreements with depositary participants or customers or by law, to pass it along to the indirect holders but does not do so. Similarly, we may want to obtain the approval of the holders to amend an indenture, to relieve us of the consequences of a default or of our obligation to comply with a particular provision of the indenture or for other purposes. In such an event, we would seek approval only from the holders, and not the indirect holders, of the securities. Whether and how the holders contact the indirect holders is up to the holders.

Special Considerations For Indirect Holders

        If you hold securities through a bank, broker or other financial institution, either in book-entry form or in street name, you should check with your own institution to find out:

•

how it handles securities payments and notices;



•

whether it imposes fees or charges;



•

how it would handle a request for the holders' consent, if ever required;



•

whether and how you can instruct it to send you securities registered in your own name so you can be a holder, if that is permitted in the future;



•

how it would exercise rights under the securities if there were a default or other event triggering the need for holders to act to protect their interests; and



•

if the securities are in book-entry form, how the depositary's rules and procedures will affect these matters.

21

---

Global Securities

        A global security is a security that represents one or any other number of individual securities held by a depositary. Generally, all securities represented by the same global securities will have the same terms.

        Each security issued in book-entry form will be represented by a global security that we deposit with and register in the name of a financial institution or its nominee that we select. The financial institution that we select for this purpose is called the depositary. Unless we specify otherwise in the applicable prospectus supplement, The Depository Trust Company, New York, New York, known as DTC, will be the depositary for all securities issued in book-entry form.

        A global security may not be transferred to or registered in the name of anyone other than the depositary, its nominee or a successor depositary, unless special termination situations arise. We describe those situations below under "Special Situations When a Global Security Will Be Terminated." As a result of these arrangements, the depositary, or its nominee, will be the sole registered owner and holder of all securities represented by a global security, and investors will be permitted to own only beneficial interests in a global security. Beneficial interests must be held by means of an account with a broker, bank or other financial institution that in turn has an account with the depositary or with another institution that does. Thus, an investor whose security is represented by a global security will not be a holder of the security, but only an indirect holder of a beneficial interest in the global security.

        If the prospectus supplement for a particular security indicates that the security will be issued in global form only, then the security will be represented by a global security at all times unless and until the global security is terminated. If termination occurs, we may issue the securities through another book-entry clearing system or decide that the securities may no longer be held through any book-entry clearing system.

Special Considerations For Global Securities

        The rights of an indirect holder relating to a global security will be governed by the account rules of the investor's financial institution and of the depositary, as well as general laws relating to securities transfers. We do not recognize an indirect holder as a holder of securities and instead deal only with the depositary that holds the global security.

        If securities are issued only in the form of a global security, an investor should be aware of the following:

•

an investor cannot cause the securities to be registered in his or her name, and cannot obtain non-global certificates for his or her interest in the securities, except in the special situations we describe below;



•

an investor will be an indirect holder and must look to his or her own bank or broker for payments on the securities and protection of his or her legal rights relating to the securities, as we describe above;



•

an investor may not be able to sell interests in the securities to some insurance companies and to other institutions that are required by law to own their securities in non-book-entry form;



•

an investor may not be able to pledge his or her interest in a global security in circumstances where certificates representing the securities must be delivered to the lender or other beneficiary of the pledge in order for the pledge to be effective;



•

the depositary's policies, which may change from time to time, will govern payments, transfers, exchanges and other matters relating to an investor's interest in a global security;

22

---

•

we and any applicable trustee have no responsibility for any aspect of the depositary's actions or for its records of ownership interests in a global security, nor do we or any applicable trustee supervise the depositary in any way;



•

the depositary may, and we understand that DTC will, require that those who purchase and sell interests in a global security within its book-entry system use immediately available funds, and your broker or bank may require you to do so as well; and



•

financial institutions that participate in the depositary's book-entry system, and through which an investor holds its interest in a global security, may also have their own policies affecting payments, notices and other matters relating to the securities.

        There may be more than one financial intermediary in the chain of ownership for an investor. We do not monitor and are not responsible for the actions of any of those intermediaries.

Special Situations When a Global Security Will Be Terminated

        In a few special situations described below, the global security will terminate and interests in it will be exchanged for physical certificates representing those interests. After that exchange, the choice of whether to hold securities directly or in street name will be up to the investor. Investors must consult their own banks or brokers to find out how to have their interests in securities transferred to their own name, so that they will be direct holders. We have described the rights of holders and street name investors above.

        Unless we provide otherwise in the applicable prospectus supplement, the global security will terminate when the following special situations occur:

•

if the depositary notifies us that it is unwilling, unable or no longer qualified to continue as depositary for that global security and we do not appoint another institution to act as depositary within 90 days;



•

if we notify any applicable trustee that we wish to terminate that global security; or



•

if an event of default has occurred with regard to securities represented by that global security and has not been cured or waived.

        The prospectus supplement may also list additional situations for terminating a global security that would apply only to the particular series of securities covered by the applicable prospectus supplement. When a global security terminates, the depositary, and not we or any applicable trustee, is responsible for deciding the names of the institutions that will be the initial direct holders.

PLAN OF DISTRIBUTION

        We may sell the securities from time to time pursuant to underwritten public offerings, negotiated transactions, block trades or a combination of these methods. We may sell the securities to or through underwriters or dealers, through agents, or directly to one or more purchasers. We may distribute securities from time to time in one or more transactions:

•

at a fixed price or prices, which may be changed;



•

at market prices prevailing at the time of sale;



•

at prices related to such prevailing market prices; or



•

at negotiated prices.

23

---

A prospectus supplement or supplements will describe the terms of the offering of the securities, including:

•

the name or names of the underwriters, if any;



•

the purchase price of the securities and the proceeds we will receive from the sale;



•

any over-allotment options under which underwriters may purchase additional securities from us;



•

any agency fees or underwriting discounts and other items constituting agents' or underwriters' compensation;



•

any public offering price;



•

any discounts or concessions allowed or reallowed or paid to dealers; and



•

any securities exchange or market on which the securities may be listed.

Only underwriters named in the prospectus supplement will be underwriters of the securities offered by the prospectus supplement.

        If underwriters are used in the sale, they will acquire the securities for their own account and may resell the securities from time to time in one or more transactions at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable underwriting agreement. We may offer the securities to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Subject to certain conditions, the underwriters will be obligated to purchase all of the securities offered by the prospectus supplement, other than securities covered by any over-allotment option. Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may change from time to time. We may use underwriters with whom we have a material relationship. We will describe in the prospectus supplement, naming the underwriter, the nature of any such relationship.

        We may sell securities directly or through agents we designate from time to time. We will name any agent involved in the offering and sale of securities and we will describe any commissions we will pay the agent in the prospectus supplement. Unless the prospectus supplement states otherwise, our agent will act on a best-efforts basis for the period of its appointment.

        We may authorize agents or underwriters to solicit offers by certain types of institutional investors to purchase securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. We will describe the conditions to these contracts and the commissions we must pay for solicitation of these contracts in the prospectus supplement.

        We may provide agents and underwriters with indemnification against civil liabilities, including liabilities under the Securities Act, or contribution with respect to payments that the agents or underwriters may make with respect to these liabilities. Agents and underwriters may engage in transactions with, or perform services for, us in the ordinary course of business.

        All securities we may offer, other than common stock, will be new issues of securities with no established trading market. Any underwriters may make a market in these securities, but will not be obligated to do so and may discontinue any market making at any time without notice. We cannot guarantee the liquidity of the trading markets for any securities.

        Any underwriter may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum

24

---

price. Syndicate-covering or other short-covering transactions involve purchases of the securities, either through exercise of the over-allotment option or in the open market after the distribution is completed, to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a stabilizing or covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time.

        Any underwriters that are qualified market makers on the Nasdaq Global Select Market may engage in passive market making transactions in the common stock on the Nasdaq Global Select Market in accordance with Regulation M under the Exchange Act, during the business day prior to the pricing of the offering, before the commencement of offers or sales of the common stock. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker's bid, however, the passive market maker's bid must then be lowered when certain purchase limits are exceeded. Passive market making may stabilize the market price of the securities at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time.

        In compliance with guidelines of the Financial Industry Regulatory Authority, or FINRA, the maximum consideration or discount to be received by any FINRA member or independent broker dealer may not exceed 8% of the aggregate amount of the securities offered pursuant to this prospectus and any applicable prospectus supplement.
