Item 1.01.  Entry into a Material Definitive Agreement

On August 27, 2009, Kratos Defense & Security Solutions, Inc. (the “Company”) entered into a placement agent agreement with B. Riley & Co., LLC (the “Placement Agent”) relating to the sale and issuance by the Company of approximately 26 million shares of the Company’s common stock to certain institutional investors.  The shares of common stock will be sold at a purchase price of $0.72 per share, for an aggregate purchase price of approximately $18.7 million. The closing of the offering is expected to take place on September 2, 2009, subject to the satisfaction of customary closing conditions.

The shares of common stock are being offered and sold pursuant to a prospectus dated August 21, 2009 and a prospectus supplement dated August 28, 2009, pursuant to the Company’s registration statement on Form S-3, as amended (File No. 333-161340), which was declared effective by the Securities and Exchange Commission on August 21, 2009.  A copy of the opinion of Morrison & Foerster LLP relating to the legality of the issuance and sale of the common stock in the offering is attached as Exhibit 5.1 hereto.

Pursuant to the terms of the placement agent agreement, the Company will pay the Placement Agent a cash fee equal to 5% of the gross proceeds from the offering, plus expenses.  The foregoing description of the placement agent agreement does not purport to be complete and is qualified in its entirety by reference to the Exhibit 10.1 hereto, which is incorporated by reference herein.

On August 28, 2009, the Company issued a press release announcing the pricing of the offering and the execution of the placement agent agreement.  A copy of the press release is attached as Exhibit 99.1 hereto.

As previously disclosed, on June 4, 2009, the Company filed a complaint in the United States District Court for the Northern District of Ohio against the lenders under its credit agreement, seeking equitable relief in the form of reformation of an error in a contract schedule.  The error resulted from the erroneous preparation of a schedule to the loan documents consisting of calculations relating to a financial covenant relating to the minimum liquidity ratio.

On August 27, 2009, the Company entered into a term sheet, which was negotiated under the jurisdiction of the United States District Court for the Northern District of Ohio, under which the parties intend to settle this dispute.  The term sheet provides that a definitive settlement agreement will be negotiated and executed on or before September 27, 2009 and, if executed, would effect the reformation of the minimum liquidity ratio in accordance with the Company’s request.  The term sheet also requires that the Company use the net proceeds from the sale of the securities in the offering to pay down the first term loan at par with no prepayment penalty or make whole payments.  The term sheet also provides that the Company will agree to pay a fee of $500,000 to its lenders in connection with the execution of a definitive settlement agreement and that the lenders will extend the term of the revolving line of credit by one year to December 31, 2012.  In addition, the term sheet provides, among other things, that the parties will execute and deliver mutual releases.  The amendments described in this paragraph will not be effective unless and until the parties have executed a definitive settlement agreement, and the Company can provide no assurance that a definitive settlement agreement will be entered into on the anticipated terms, or at all.

Item 2.03.  Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

The information set forth in the last two paragraphs of Item 1.01 is hereby incorporated by reference into this Item 2.03.

Ladies and Gentlemen:

1.             Introduction.  Kratos Defense & Security Solutions, Inc., a Delaware corporation (the “Company”), proposes, pursuant to the terms of this Placement Agent Agreement (this “Agreement”) to sell to certain institutional investors (the “Purchasers”) up to an aggregate of 26,000,000 shares (the “Shares”) of common stock, $0.001 par value per share (the “Common Stock”), of the Company. The Company hereby confirms that B. Riley & Co., LLC is acting as the exclusive placement agent (the “Placement Agent”) in accordance with the terms and conditions hereof.

2.             Agreement to Act as Placement Agent; Placement of Shares.  On the basis of the representations, warranties and agreements of the Company herein contained, and subject to all the terms and conditions of this Agreement:

(a)           The Company hereby authorizes the Placement Agent to act as its exclusive agent to solicit offers for the purchase of all or part of the Shares from the Company in connection with the proposed offering of the Shares (the “Offering”).  Until the Closing Date (as defined in Section 4 hereof), the Company shall not, without the prior written consent of the Placement Agent, solicit or accept offers to purchase Shares otherwise than through the Placement Agent.

(b)           The Company hereby acknowledges that the Placement Agent, as an agent of the Company, shall use its reasonable best efforts to solicit offers from potential purchasers to purchase the Shares from the Company on the terms and subject to the conditions set forth in the Prospectus (as defined below).  The Placement Agent has no authority to bind the Company with respective to any prospective offer to purchase the Shares.  The Placement Agent shall use commercially reasonable efforts to assist the Company in obtaining performance by each Purchaser whose offer to purchase Shares was solicited by the Placement Agent and accepted by the Company, but the Placement Agent shall not, except as otherwise provided in this Agreement, be obligated to disclose the identity of any potential purchaser or have any liability to the Company in the event any such purchase is not consummated for any reason.  Under no circumstances will the Placement Agent be obligated to underwrite or purchase any Shares for its own accounts and, in soliciting offers to purchase the Shares, the Placement Agent shall act solely as the Company’s agent and not as a principal.  Notwithstanding the foregoing, it is understood and agreed that the Placement Agent (or its affiliates) may, solely at their discretion and without any obligation to do so, purchase Shares as a principal.

(c)           Subject to the provisions of this Section 2, offers for the purchase of Shares shall be solicited by the Placement Agent as agent for the Company at such times and in such amounts as the Placement Agent deems advisable.  The Placement Agent shall communicate to the Company, orally or in writing, each reasonable offer to purchase Shares received by it as agent of the Company.  The Company shall have the sole right to accept offers to purchase the Shares and may reject any such offer, in whole or in part.  The Placement Agent shall have the right, in its discretion reasonably exercised, without notice to the Company, to reject any offer to purchase Shares received by it, in whole or in part, and any such rejection shall not be deemed a breach of this Agreement.

(d)           The Shares are being sold to the Purchasers at a price of $0.72 per share.

(e)           As compensation for services rendered, on the Closing Date, the Company shall pay to the Placement Agent by wire transfer of immediately available funds to an account or accounts designated by the Placement Agent, an aggregate amount equal to 5% of the aggregate gross proceeds received by the Company from the sale of the Shares on such Closing Date.

(f)            No Shares which the Company has agreed to sell pursuant to this Agreement shall be deemed to have been purchased and paid for, or sold by the Company, until such Shares shall have been delivered to the Purchaser thereof against payment by such Purchaser.  If the Company shall default in its obligations to deliver Shares to a Purchaser whose offer it has accepted, the Company shall indemnify and hold the Placement Agent harmless against any loss, claim, damage or expense arising from or as a result of such default by the Company in accordance with Section 8 herein.

3.             Representations and Warranties of the Company.  The Company represents and warrants to, and agrees with, the Placement Agent that:

indemnified party otherwise than under this Section 8.  If any such action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense of such action with counsel reasonably satisfactory to the indemnified party (which counsel shall not, except with the written consent of the indemnified party, be counsel to the indemnifying party).  After notice from the indemnifying party to the indemnified party of its election to assume the defense of such action, except as provided herein, the indemnifying party shall not be liable to the indemnified party under Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense of such action other than reasonable costs of investigation; provided, however, that any indemnified party shall have the right to employ separate counsel in any such action and to participate in the defense of such action but the fees and expenses of such counsel (other than reasonable costs of investigation which shall remain the expense of the Company) shall be at the expense of such indemnified party unless (i) in the case of a Placement Agent Indemnified Party, the employment thereof has been specifically authorized in writing by the Company in the case of a claim for indemnification under Section 8(a) or Section 2(f), or (ii) such indemnified party shall have been advised by its counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party, or (iii) the indemnifying party has failed to assume the defense of such action and employ counsel reasonably satisfactory to the indemnified party within a reasonable period of time after notice of the commencement of the action or the indemnifying party does not diligently defend the action after assumption of the defense, in which case, if such indemnified party notifies the indemnifying party in writing that it elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of (or, in the case of a failure to diligently defend the action after assumption of the defense, to continue to defend) such action on behalf of such indemnified party and the indemnifying party shall be responsible for legal or other expenses subsequently incurred by such indemnified party in connection with the defense of such action; provided, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys at any time for all such indemnified parties (in addition to any local counsel), which firm shall be designated in writing by the Placement Agent if the indemnified parties under this Section 8 consist of any Placement Agent Indemnified Party or by the Company if the indemnified parties under this Section 8 consist of any Company Indemnified Parties.  Subject to this Section 8(c), the amount payable by an indemnifying party under Section 8 shall include, but not be limited to, (x) reasonable legal fees and expenses of counsel to the indemnified party and any other expenses in investigating, or preparing to defend or defending against, or appearing as a third party witness in respect of, or otherwise incurred in connection with, any action, investigation, proceeding or claim, and (y) all amounts paid in settlement of any of the foregoing.  No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of judgment with respect to any pending or threatened action or any claim

20

whatsoever, in respect of which indemnification or contribution could be sought under this Section 8 (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party in form and substance reasonably satisfactory to such indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.  Subject to the provisions of the following sentence, no indemnifying party shall be liable for settlement of any pending or threatened action or any claim whatsoever that is effected without its written consent (which consent shall not be unreasonably withheld or delayed), but if settled with its written consent, or if its consent has been unreasonably withheld or delayed, or if there be a judgment for the plaintiff in any such matter, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.  In addition, if at any time an indemnified party shall have requested that an indemnifying party reimburse the indemnified party for reasonable fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated herein effected without its written consent if (i) such settlement is entered into more than forty-five (45) days after receipt by such indemnifying party of the request for reimbursement, (ii) such indemnifying party shall have received notice of the terms of such settlement at least thirty (30) days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

(d)           If the indemnification provided for in this Section 8 is unavailable or insufficient to hold harmless an indemnified party under Section 8(a) or Section 8(b), then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid, payable or otherwise incurred by such indemnified party as a result of such loss, claim, damage, expense or liability (or any action, investigation or proceeding in respect thereof), as incurred, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Placement Agent on the other hand from the ) Offering of the Shares, or (ii) if the allocation provided by clause (i) of this Section 8(d) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) of this Section 8(d) but also the relative fault of the Company on the one hand and the Placement Agent on the other with respect to the statements, omissions, acts or failures to act which resulted in such loss, claim, damage, expense or liability (or any action, investigation or proceeding in respect thereof) as well as any other relevant equitable considerations.  The relative benefits received by the Company on the one hand and the Placement Agent on the other with respect to such Offering shall be deemed to be in the same proportion as the total net proceeds from the Offering of the Shares purchased under this Agreement (before deducting expenses) received by the Company bear to the total compensation received by the Placement Agent in connection with the Offering, in each case as set forth in the table on the cover page of the Prospectus.  The relative fault of the Company on the one hand and the Placement Agent on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact

21

relates to information supplied by the Company on the one hand or the Placement Agent on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement, omission, act or failure to act; provided that the parties hereto agree that the written information furnished to the Company by or on behalf of the Placement Agent for use in any Registration Statement or the Prospectus, or in any amendment or supplement thereto, consists solely of the Placement Agent’s Information.  The Company and the Placement Agent agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein.  The amount paid or payable by an indemnified party as a result of the loss, claim, damage, expense, liability, action, investigation or proceeding referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating, preparing to defend or defending against or appearing as a third party witness in respect of, or otherwise incurred in connection with, any such loss, claim, damage, expense, liability, action, investigation or proceeding.  Notwithstanding the provisions of this Section 8(d), the Placement Agent shall not be required to contribute any amount in excess of the total compensation received by the Placement Agent in accordance with Section 2(e) less the amount of any damages which the Placement Agent has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement, omission or alleged omission, act or alleged act or failure to act or alleged failure to act.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

9.             Termination.  The obligations of the Placement Agent and the Purchasers hereunder may be terminated by the Placement Agent, in its absolute discretion by notice given to the Company prior to delivery of and payment for the Shares if, prior to that time, any of the events described in Section 7(f), Section 7(g) or Section 7(h) have occurred or if the Purchasers shall decline to purchase the Shares for any reason permitted under this Agreement.
