WIRELESS FACILITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) (1) Organization and Summary of Significant Accounting Policies (a) Description of Business Wireless Facilities, Inc. ("WFI") was formed in the state of New York on December 19, 1994, began operations in March 1995 and was reincorporated in Delaware in 1998. WFI provides a full suite of outsourcing services to wireless carriers and equipment vendors, including the design, deployment and management of client networks. WFI's customers include both early-stage and mature providers of cellular, PCS and broadband data services and equipment. WFI's engagements range from small contracts for the deployment of a single cell, to large multi-year turnkey contracts. These services are billed either on a time and materials basis or on a fixed price, time certain basis. (b) Basis of Presentation The information as of March 31, 2001, and for the three month periods ended March 31, 2000 and 2001 is unaudited. In the opinion of management, these consolidated financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the results of operations for the interim periods presented. Interim operating results are not necessarily indicative of operating results expected in subsequent periods or for the year as a whole. These consolidated financial statements should be read in conjunction with the consolidated financial statements and the related notes included in WFI's annual consolidated financial statements for the fiscal year ended December 31, 2000, filed on Form 10-K with the Securities and Exchange Commission. The consolidated financial statements include the accounts of WFI and its wholly-owned and majority-owned subsidiaries. WFI and its subsidiaries are collectively referred to herein as the "Company." All intercompany transactions have been eliminated in consolidation. Investments accounted for using the cost method include companies in which the Company owns less than 20% and for which the Company has no significant influence. Investments accounted for using the equity method include companies in which the Company owns more than 20% but less than 50%, or for which the Company is considered to have significant influence. (c) Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. (d) Reclassifications Certain prior period amounts have been reclassified to conform with the current period presentation. (2) Recent Events On February 9, 2001, the Company executed an amended and restated credit agreement, which increased the aggregate commitment provided by the Company's credit facility from $50 million to $100 million. Pursuant to the amended and restated credit agreement, the credit facility is due in February 2004 and bears interest, at the Company's discretion, at either (i) the greater of the bank prime rate and the Federal Funds Rate 6

WIRELESS FACILITIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) (Unaudited) plus .5%, plus a margin of 1.25%, the base rate margin, or (ii) at the London Interbank Offering Rate (LIBOR) plus 2.25%, the LIBOR rate margin. Beginning with the third quarter of 2001, the base rate margin and the LIBOR rate margin are to be determined based on certain financial ratios as of the end of the most recently ended fiscal quarter which will result in margins ranging from .75% to 1.50% and 1.75% to 2.50%, respectively. The credit facility is secured by substantially all of the Company's assets. The credit agreement contains restrictive covenants, which, among other things, require maintenance of certain financial ratios. On February 23, 2001, the Company announced that it received notice of contract suspension and termination from Metricom, Inc., with regard to remaining RF engineering and deployment services for Metricom's data network buildout, which would have been provided during the first and second quarter of fiscal 2001. Beyond the second quarter, the Company does not anticipate any material impact related to Metricom's notice of contract suspension and termination. On March 2, 2001, the Company's Board of Directors approved a voluntary stock option cancel and regrant program for employees. The program provides employees with the opportunity to cancel all of their existing and outstanding stock options granted to them on or after September 30, 2000 and before March 30, 2001, and some or all of their existing and outstanding stock options granted to them prior to September 30, 2000, in exchange for the right to receive a new option grant for an equal number of shares to be granted at a future date. The new options will be granted no earlier than six months and one day after the cancellation date, March 30, 2001, and the exercise price of the new options is to be based on the trading price of the Company's common stock on the date of the new option grants. The exchange program is designed to comply with FASB Interpretation No. 44 "Accounting for Certain Transactions Involving Stock Compensation." On April 20, 2001, our customer Advanced Radio Telecom filed for bankruptcy protection causing the Company to recognize a bad debt expense of $3.5 million and a realized loss on an investment in Advanced Radio Telecom securities of $1.1 million for the first quarter and thereby negatively affecting the Company's profitability. (3) Net Income (Loss) Per Common Share The Company calculates net income (loss) per share in accordance with SFAS No. 128, Earnings Per Share. Under SFAS No. 128, basic net income (loss) per common share is calculated by dividing net income (loss) by the weighted- average number of common shares outstanding during the reporting period. Diluted net income (loss) per common share reflects the effects of potentially dilutive securities. Weighted average shares used to compute net income (loss) per share are presented below (in millions): Three Months Ended March 31, --------- 2000 2001 ---- ---- Weighted-average shares, basic..................................... 40.5 43.7 Dilutive effect of stock options................................... 7.4 -- Dilutive effect of warrants........................................ 1.0 -- ---- ---- Weighted-average shares, fully diluted............................. 48.9 43.7 ==== ==== Options to purchase .4 million and 9.8 million shares of common stock for the three months ended March 31, 2000 and 2001, respectively, were not included in the calculation of diluted net income (loss) per share because the effect of these instruments was anti-dilutive. 7

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") This report contains forward-looking statements. These statements relate to future events or our future financial performance. In some cases, you can identify forward-looking statements by terminology such as "may," "will," "should," "expect," "plan," "anticipate," "believe," "estimate," "predict," "potential" or "continue," the negative of such terms or other comparable terminology. These statements are only predictions. Actual events or results may differ materially. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance or achievements. Moreover, neither we, nor any other person, assumes responsibility for the accuracy and completeness of the forward-looking statements. We are under no obligation to update any of the forward-looking statements after the filing of this Quarterly Report on Form 10-Q to conform such statements to actual results or to changes in our expectations. The following discussion should be read in conjunction with our consolidated financial statements and the related notes and other financial information appearing elsewhere in this Form 10-Q. Readers are also urged to carefully review and consider the various disclosures made by us which attempt to advise interested parties of the factors which affect our business, including without limitation the disclosures made under the caption "Management's Discussion and Analysis of Financial Condition and Results of Operations," under the caption "Risk Factors," and the audited consolidated financial statements and related notes included in our Annual Report filed on Form 10-K for the year ended December 31, 2000 and other reports and filings made with the Securities and Exchange Commission. Overview Wireless Facilities, Inc. offers network business consulting, network planning, design and deployment, and network operations and maintenance services to the wireless telecommunications industry. For the three months ended March 31, 2001, our consulting, design and deployment, and network management segments contributed to 3%, 72% and 25% of our revenues, respectively. During 2000, we formed a subsidiary in the United Kingdom, Wireless Facilities International, Ltd. ("WFIL"). WFIL began servicing existing contracts and entering into new contracts in Europe, the Middle East and Africa ("EMEA") in April 2000. During the three months ended March 31, 2001, we performed work in 44 countries. These contracts include services performed for many of the latest wireless technologies, including UMTS (Universal Mobile Telephone Service), broadband wireless applications, and voice and video applications. Revenues from our international operations contributed 33% of our total revenues for the three months ended March 31, 2001. Revenues from network planning, design and deployment contracts include fixed price contracts which are recognized using the percentage-of-completion method. Under the percentage-of-completion method of accounting, expenses on each project are recognized as incurred, and revenues are recognized based on a comparison of the current costs incurred for the project to date compared to the then estimated total costs of the project from start to completion. Accordingly, revenue recognized in a given period depends on the costs incurred on each individual project and the current estimate of the total costs to complete a project, determined at that time. As a result, gross margins for any single project may fluctuate from period to period. The full amount of an estimated loss is charged to operations in the period it is determined that a loss will be realized from the performance of a contract. For business consulting, network planning, design and deployment contracts offered on a time and expense basis, we recognize revenues as services are performed. We typically charge a fixed monthly fee for ongoing radio frequency optimization and network operations and maintenance services. With respect to these services, we recognize revenue as services are performed. Cost of revenues includes direct compensation and benefits, living and travel expenses, payments to third-party sub-contractors, allocation of overhead, costs of expendable computer software and equipment, and other direct project-related expenses. 9

Selling, general and administrative expenses include compensation and benefits, computer software and equipment, facilities expenses and other expenses not related directly to projects. Our sales personnel have, as part of their compensation package, incentives based on their productivity. As of March 31, 2001, we had completed the first phase of implementing a new financial management and accounting software program in our domestic operations. Such software is expected to better accommodate our growth. We expect to incur expenses in subsequent periods related to licensing the software package and related personnel costs associated with completing its implementation in our domestic operations and phasing in its implementation in our international operations. We may incur expenses related to a given project in advance of the commencement of the project as we increase our personnel to work on the project. New hires typically undergo training on our systems and project management process prior to being deployed on a project. Due to the recent downturn in the financial markets in general, and specifically within the telecommunications industry, many of our customers are having trouble raising money in the capital markets to fund the expansion of their businesses, including telecom network deployments and upgrades. The recent volatility of the financial markets and slowdown in the U.S. economy has also intensified the uncertainty experienced by many of our customers, who are finding it increasingly difficult to predict demand for their products and services. As a result, many of our customers are slowing or postponing the deployment of new wireless networks and the development of new technologies and products, which has reduced the demand for our services. Some of our customers have recently cancelled or suspended their contracts with us and many of our customers or potential customers have postponed entering into new contracts for our services. For example, during the first quarter of 2001, we announced that we received notice of contract suspension and termination from Metricom, Inc., which would have been provided during the first and second quarter of our fiscal 2001. Also due to the difficult financing and economic conditions, some of our customers may not be able to pay us for services that we have already performed. If we are not able to collect amounts owed to us, we may be required to write-off or convert significant amounts of our accounts receivable. For example, our customer Advanced Radio Telecom filed for bankruptcy protection on April 20, 2001, causing us to recognize a bad debt expense of $3.5 million for the first quarter and thereby negatively affecting our profitability. Also, during the first quarter of fiscal 2001, we converted $1.4 million of our outstanding accounts receivable balance to a note receivable, though this did not affect net income. Also, some of our contracts with our customers include billing milestones, whereby we do not bill for work performed until certain milestones are reached. However, we recognize revenue under the percentage-of- completion method of accounting. If a contract is terminated by a customer or modified before a milestone is reached, we generally will be required to renegotiate the terms of payment for work performed but not yet billed. As a result of the market conditions described above, we have recently begun to experience this with a number of our contracts that contain billing milestones. Due to the circumstances surrounding such cancellations or modifications and the financial condition of the related customers, the amount we ultimately collect from such customers may be, and often is, discounted from the amount we have previously recorded in unbilled accounts receivable and revenue. Because we are not able to reduce our costs as fast as our revenues may decline, our costs as a percentage of revenues may increase and, correspondingly, our net earnings may decline disproportionately to any decreases in revenues. We have experienced this challenge particularly with respect to managing our employee base, and this has resulted in underutilization of employees due to the sudden reduction in the demand for our services during the first quarter of fiscal 2001. In response to these factors and the lack of visibility and uncertain market conditions, we have taken steps and are continuing to take steps to reduce our level of expenditures. Specifically, we have reduced our headcount by approximately 8.3% since December 31, 2000 and have also implemented a more stringent expenditure approval policy, in an effort to further reduce our costs. We expect to continue to review our internal processes throughout 2001 and make further adjustments as necessary. Results of Operations Comparison of Results for the Three Months Ended March 31, 2000 to the Three Months Ended March 31, 2001 Revenues. Revenues increased 22% from $43.3 million for the three months ended March 31, 2000 to $52.7 million for the three months ended March 31, 2001. The $9.4 million increase was primarily attributable 10

to the addition of new contracts, including contracts in our business development and network management segments, not included in the three months ended March 31, 2000. Another significant factor for the increase was our expansion into international markets. Revenues from international markets comprised 27% of our total revenues during the three months ended March 31, 2000, compared to 33% of our total revenues during the three month period ended March 31, 2001. Cost of Revenues. Cost of revenues increased 55% from $25.3 million for the three months ended March 31, 2000 to $39.1 million for the three months ended March 31, 2001, primarily due to increased staffing in support of new contracts. Gross margin was 42% of revenues for the three months ended March 31, 2000 compared to 26% for the three months ended March 31, 2001. The decrease in gross margin is due primarily to the recent decline in the economy and specifically, in wireless telecommunications infrastructure spending, which resulted in the suspension and termination of the Metricom, Inc. and Advanced Radio Telecom contracts. The sudden and unexpected loss of these customers caused the expected overall margin on the related contracts to decrease and therefore a cumulative entry was recorded to adjust the margin recorded to date to the expected final margin on the contracts. Additionally, gross margins decreased because we were unable to reduce our costs as fast as our revenues declined due to the lengthy process and costs associated with demobilizing our project teams. Selling, General and Administrative Expenses. Selling, general and administrative expenses increased 299% from $7.6 million for the three months ended March 31, 2000 to $30.3 million for the three months ended March 31, 2001. As a percentage of revenues, selling, general and administrative expenses increased from 18% for the three months ended March 31, 2000 to 57% for the three months ended March 31, 2001. The increase is due primarily to the recent downturn in the telecommunications industry, which resulted in lower utilization rates and additional bad debt expense. Depreciation and Amortization Expense. Depreciation and amortization expense increased 391% from $1.1 million for the three months ended March 31, 2000 to $5.4 million for the three months ended March 31, 2001. The increase is primarily due to goodwill and other identifiable intangibles purchased in our acquisitions completed subsequent to March 31, 2000, which contributed to our increase in contracts, revenues and overall operations. Other Income (Expense). For the three months ended March 31, 2000, other income was $0.5 million as compared to other expense of $2.2 million for the three months ended March 31, 2001. This net change totaling $2.7 million was primarily attributable to higher interest expense due to increased debt outstanding during the periods under comparison combined with the realized loss on available-for-sale investment securities related to the bankruptcy filing of Advanced Radio Telecom. Provision for Income Taxes. Our provisional income tax rate as a percentage of income before taxes increased from 40% for the three months ended March 31, 2000, to 65% for the three months ended March 31, 2001. The increase is primarily attributable to a decrease in earnings combined with an increase in the valuation allowance generated by net losses from some of our foreign operations. Liquidity and Capital Resources Our sources of cash liquidity included cash, cash from operations, amounts available under credit facilities, and other external sources of funds. As of March 31, 2001, we had cash of $17.7 million and $27.0 million outstanding on our $100 million line of credit. Cash used in operations is primarily derived from our contracts in process and changes in working capital. Cash used in operations was $21.0 million and $2.8 million for the three months ended March 31, 2000 and 2001, respectively. Cash used in investing activities was $3.9 million and $1.7 million for the three months ended March 31, 2000 and 2001, respectively. Investing activities for the three months ended March 31, 2000 consisted primarily of cash paid for the acquisition of the assets from The Walter Group in January 2000 and the acquisition of a 11

network operations center in March of 2000. Investing activities for the three months ended March 31, 2001 consisted primarily of capital expenditures. Cash provided by financing activities for the three months ended March 31, 2000 was $15.3 million, which was primarily derived from borrowings under the line of credit. Cash provided by financing activities was $3.9 million for the three months ended March 31, 2001. Financing activities for this period primarily consisted of proceeds from the issuance of common stock and borrowings under our line of credit. At March 31, 2001, $27.0 million was outstanding under our line of credit. This credit facility is due in February 2004 and bears interest, at our discretion, at either (i) the greater of the bank prime rate or the Federal Funds Rate plus .5%, plus a margin of 1.25%, the base rate margin, or (ii) at the London Interbank Offering Rate ("LIBOR") plus a margin of 2.25%, the LIBOR rate margin. Beginning in the third quarter of 2001, the base rate margin and the LIBOR rate margin is to be determined based on certain financial ratios as of the end of the most recently ended fiscal quarter which will result in margins ranging from .75% to 1.50% and 1.75% to 2.50%, respectively. We have no material cash commitments other than obligations under our credit facilities, promissory notes, and operating and capital leases. Future capital requirements will depend upon many factors, including the timing of payments under contracts and increases in personnel in advance of new contracts. Risk Factors That May Affect Results of Operations and Financial Condition You should carefully consider the following risk factors and all other information contained herein as well as the information included in our Annual Report on Form 10-K for the year ended December 31, 2000, and other reports and filings made with the Securities and Exchange Commission before investing in our common stock. Investing in our common stock involves a high degree of risk. Risks and uncertainties, in addition to those we describe below, that are not presently known to us or that we currently believe are immaterial may also impair our business operations. If any of the following risks occur, our business could be harmed, the price of our common stock could decline and you may lose all or part of your investment. See the note regarding forward-looking statements included at the beginning of Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations. We expect our quarterly results to fluctuate. If we fail to meet earnings estimates, our stock price could decline. Our quarterly and annual operating results have fluctuated in the past and will vary in the future due to a variety of factors, many of which are outside of our control. The factors outside of our control include: . telecom market conditions and economic conditions generally; . the timing and size of network deployment by our carrier customers and the timing and size of orders for network equipment built by our vendor customers; . fluctuations in demand for our services; . the length of sales cycles; . reductions in the prices of services offered by our competitors; and . costs of integrating technologies or businesses. The factors substantially within our control include: . changes in the actual and estimated costs and timing to complete fixed- price, time-certain projects; . the timing of expansion into new markets, both domestically and internationally; and . the timing and payments associated with possible acquisitions. 12

Due to these factors, quarterly revenues, expenses and results of operations have recently varied significantly and could continue to vary significantly in the future. You should take these factors into account when evaluating past periods, and, because of the potential variability due to these factors, you should not rely upon results of past periods as an indication of our future performance. In addition, we may from time to time provide estimates of our future performance. Such estimates are inherently uncertain and actual results are likely to deviate, perhaps substantially, from such estimates as a result of the many risks and uncertainties in our business, including those set forth in these risk factors. We undertake no duty to update such estimates if given. In addition, the long-term viability of our business could be negatively impacted if there were a sustained downward trend in our revenues and results of operations. Because our operating results may vary significantly from quarter to quarter based upon the factors described above, results may not meet the expectations of securities analysts and investors, and this could cause the price of our common stock to decline significantly. We have recently begun to experience a negative impact to our earnings and stock price as a result of the factors that may cause our quarterly results to fluctuate. We expect that this negative trend may continue for the foreseeable future, and at least through the second quarter of 2001. Due to the recent downturn in the financial markets in general, and specifically the slowdown in wireless telecommunications infrastructure spending, some of our customers have recently cancelled or suspended their contracts with us and many of our customers or potential customers have postponed entering into new contracts for our services. In addition, unfavorable economic conditions are causing some of our customers to take longer to pay us for services we perform, increasing the average number of days that our sales are outstanding. Also due to the difficult financing and economic conditions, some of our customers may not be able to pay us for services that we have already performed. If we are not able to collect amounts due to us, we may be required to write-off or convert significant amounts of our accounts receivable, as we did during the first quarter of 2001 with respect to the recognition of a $3.5 million bad debt expense resulting from Advanced Radio Telecom's filing for bankruptcy protection and the conversion of $1.4 million of our outstanding accounts receivable to a note receivable. Also, if a contract that is structured with billing milestones is terminated by a customer or modified before a milestone is reached, we generally will be required to renegotiate the terms of payment for work performed but not yet billed. Due to circumstances surrounding such cancellations or modifications and the financial condition of the related customers, the amount we ultimately collect from such customers may be, and often is, discounted from the amount we have previously recorded in unbilled accounts receivable and revenue. Because we are not able to reduce our costs as fast as our revenues may decline, our costs as a percentage of revenues may increase and, correspondingly, our net earnings may decline disproportionately to any decrease in revenues. If we restructure our business in an effort to minimize our expenses, we may incur associated charges. As a result of these and other factors, it has become extremely difficult to forecast our future revenues and earnings, and any predictions we make are subject to significant change and are very uncertain. Our success is dependent on the continued growth in the deployment of wireless networks; and to the extent that such growth cannot be sustained our business may be harmed. The wireless telecom industry has historically experienced a dramatic rate of growth both in the United States and internationally. Recently, however, many telecom carriers have been re-evaluating their network deployment plans in response to downturns in the capital markets, changing perceptions regarding industry growth and the adoption of new wireless technologies, and a general economic slowdown in the United States. It is difficult to predict whether these changes will result in a sustained downturn in the telecom industry. If the rate of growth continues to slow and carriers continue to reduce their capital investments in wireless infrastructure or fail to expand into new geographies, our business will be significantly harmed. The uncertainty associated with rapidly changing telecommunications technologies may also continue to negatively impact the rate of deployment of wireless networks and the demand for our services. Telecommunications service providers face significant challenges in assessing consumer demand and acceptance of rapidly changing enhanced telecommunication capabilities. If telecommunications service providers continue to perceive that the rate of acceptance of next generation telecommunications products will 13

grow more slowly than previously expected, they may continue to slow their development of next generation technologies. Any significant sustained slowdown will further reduce the demand for our services and adversely affect our financial results. Our revenues will be negatively impacted if there are delays in the deployment of new wireless networks. A significant portion of our revenue is generated from new licensees seeking to deploy their networks. To date, the pace of network deployment has sometimes been slower than expected, due in part to difficulty experienced by holders of licenses in raising the necessary financing, and there can be no assurance that future bidders for licenses will not experience similar difficulties. There has also been substantial regulatory uncertainty regarding payments owed to the United States Government by past successful wireless bidders, and such uncertainty has delayed network deployments. In addition, factors adversely affecting the demand for wireless services, such as allegations of health risks associated with the use of cellular phones, could slow or delay the deployment of wireless networks. These factors, as well as future legislation, delays in granting the use of spectrum by the United States Government, legal decisions and regulation may slow or delay the deployment of wireless networks, which, in turn, could harm our business. If our customers do not receive sufficient financing, our business may be seriously harmed. Some of our customers and potential customers are companies with limited or no operating histories and limited financial resources. These customers often must obtain significant amounts of financing to pay for their spectrum licenses, fund operations and deploy their networks. Other customers of ours rely upon outside financing to pay the considerable costs of deploying their networks. In either instance, we frequently work with such companies prior to their receipt of financing. If these companies fail to receive adequate financing or experience delays in receiving financing, particularly after we have begun working with them, our results of operations may be harmed. Our success is dependent on the continued trend toward outsourcing wireless telecom services. Our success is dependent on the continued trend by wireless carriers and network equipment vendors to outsource for their network design, deployment and management needs. If wireless carriers and network equipment vendors elect to perform more network deployment services themselves, our revenues may decline and our business would be harmed. A loss of one or more of our key customers or delays in project timing for such customers could cause a significant decrease in our net revenues. We have derived, and believe that we will continue to derive, a significant portion of our revenues from a limited number of customers. We anticipate that our key customers will change in the future as current projects are completed and new projects begin. The services required by any one customer can be limited by a number of factors, including industry consolidation, technological developments, economic slowdown and internal budget constraints. None of our customers is obligated to purchase additional services and most of our customer contracts can be terminated without cause or penalty by the customer on notice to us of 90 days or less. As a result of these factors, the volume of work performed for specific customers is likely to vary from period to period, and a major customer in one period may not use our services in a subsequent period. Accordingly, we cannot be certain that present or future customers will not terminate their network service arrangements with us or significantly reduce or delay their contracts. For example, during the first quarter of 2001, we announced that we received notice of contract suspension and termination from Metricom, Inc., which would have been provided during the first and second quarter of our fiscal 2001. Even though we do not expect any material impact related to Metricom's notice of contract suspension and cancellation beyond the second quarter, any other termination, change, reduction or delay in our projects could seriously harm our business. 14

The consolidation of equipment vendors or carriers could impact our business. Recently, the wireless telecom industry has been characterized by significant consolidation activity. This consolidation may lead to a greater ability among equipment vendors and carriers to provide a full suite of network services, and could simplify integration and installation, which may lead to a reduction in demand for our services. Moreover, the consolidation of equipment vendors or carriers could have the effect of reducing the number of our current or potential customers, which could result in their increased bargaining power. This potential increase in bargaining power could create competitive pressures whereby a particular customer may request our exclusivity with them in a particular market and put downward pressure on the prices we charge for our services. Accordingly, we may not be able to represent some customers who wish to retain our services. We may not be able to hire and retain a sufficient number of qualified engineers or other employees to sustain our growth, meet our contract commitments or maintain the quality of our services. To the extent we continue to grow, our future success will depend on our ability to hire and retain additional highly skilled engineering, managerial, marketing and sales personnel. Competition for such personnel is intense, especially for engineers, and project managers and we may be unable to attract sufficiently qualified personnel in adequate numbers to meet the demand for our services in the future. In addition, as of March 31, 2001, 21% of our employees in the United States were working under H-1B visas. H-1B visas are a special class of nonimmigrant working visas for qualified aliens working in specialty occupations, including, for example, radio frequency engineers. We are aware that the Department of Labor has issued interim final regulations that place greater requirements on H-1B dependent companies, such as ours, and may restrict our ability to hire workers under the H-1B visa category in the future. In addition, immigration policies are subject to rapid change and any significant changes in immigration law or regulations may further restrict our ability to continue to employ or to hire new workers on H-1B visas and could harm our business. A significant percentage of our revenue is accounted for on a percentage-of- completion basis which could cause our quarterly results to fluctuate. A significant percentage of our revenue is derived from fixed priced contracts which are accounted for on a percentage-of-completion basis. The portion of our revenue from fixed price contracts accounted for approximately 42% of our revenues for the quarter ended March 31, 2001. With the percentage- of-completion method, in each period we recognize expenses as they are incurred and we recognize revenue based on a comparison of the current costs incurred for the project to the then estimated total costs of the project. Accordingly, the revenue we recognize in a given quarter depends on the costs we have incurred for individual projects and our then current estimate of the total remaining costs to complete individual projects. If in any period we significantly increase our estimate of the total costs to complete a project, we may recognize very little or no additional revenue with respect to that project. As a result, our gross margin in such period and in future periods may be significantly reduced and in some cases we may recognize a loss on individual projects prior to their completion. For example, in 1999 we revised the estimated costs to complete two large contracts which resulted in a reduction of gross margins of 9.9% in the first quarter of 1999 and 6.9% in the second quarter of 1999. To the extent that our estimates fluctuate over time or differ from actual requirements, gross margins in subsequent quarters may vary significantly from our estimates and could harm our business and financial results. Similarly, the cancellation or modification of a contract which is accounted for on a percentage-of-completion basis may adversely affect our gross margins for the period during which the contract is modified or cancelled. Under certain circumstances, a cancellation or modification of a fixed-price contract could also result in us being required to reverse revenue that was recognized in a prior period, which could significantly reduce the amount of revenues recognized for the period in which the adjustment is made. For example, if we have a three year fixed price contract where the contract fee is $1 million and the initial estimated costs associated with the contract are $550,000, and if, during the first year we incur $220,000 in costs related to the contract and correspondingly estimate that the contract is 40% complete, then under the percentage-of-completion 15

accounting method we would recognize 40%, or $400,000 in revenue during the first year of the contract. If, during the second year of the contract the project is terminated with 35% of the services deemed provided to the client, then the total revenue for the project would be adjusted downward to $350,000, and the revenue recognizable during the second year would be the total revenue earned to date, the $350,000 less the revenue previously recognized or $400,000, resulting in a reversal of $50,000 of revenue previously recognized. In the first quarter of 2001, we experienced gross margin adjustments related to the suspension and termination of the Metricom, Inc. and Advanced Radio Telecom contracts. To the extent we experience adjustments such as those described above, our revenues and profit margins will be adversely affected. Our business may be harmed if we maintain or increase our staffing levels in anticipation of one or more projects and underutilize our personnel because such projects are delayed, reduced or terminated. Since our business is driven by large, and sometimes multi-year, contracts, we forecast our personnel needs for future projected business. If we maintain or increase our staffing levels in anticipation of one or more projects and such projects are delayed, reduced or terminated, we may underutilize these additional personnel, which would increase our general and administrative expenses, reduce our earnings and possibly harm our business. Additionally, due to recent market conditions, we are faced with the challenge of managing the appropriate size of our workforce in light of projected demand for our services. If we maintain a workforce sufficient to support a resurgence in demand, then in the meantime our general and administrative expenses will be high relative to our revenues and our profitability will suffer. Alternatively, if we reduce the size of our workforce too quickly in response to any decrease in the demand for our services, then our ability to quickly respond to any resurgence in demand will be impaired. As a result, to the extent that we fail to successfully manage this challenge our financial results will be harmed. Our short operating history and recent growth in expanding services limits our ability to forecast operating results. We have generated revenues for only six years and, thus, we have only a short history from which to predict future revenues. This limited operating experience, together with the dynamic market environment in which we operate, including fluctuating demand for our services, reduces our ability to accurately forecast our quarterly and annual revenues. Further, we plan our operating expenses based primarily on these revenue projections. Because most of our expenses are incurred in advance of anticipated revenues, we may not be able to decrease our expenses in a timely manner to offset any unexpected shortfall in revenues. For further financial information relating to our business, see "Management's Discussion and Analysis of Financial Condition and Operating Results." Our operating results may suffer because of competition in the wireless services industry. The network services market is highly competitive and fragmented and is served by numerous companies. Many of these competitors have significantly greater financial, technical and marketing resources, generate greater revenues and have greater name recognition and experience than us. We do not know of any competitors that are dominant in our industry. For a further description of our competition, see "Business-- Competition" in our Annual Report on Form 10-K for the year ended December 31, 2000. We believe that the principal competitive factors in our market include the ability to deliver results within budget and on time, reputation, accountability, project management expertise, industry experience and pricing. In addition, expertise in new and evolving technologies, such as wireless Internet services, has become increasingly important. We also believe our ability to compete depends on a number of factors outside of our control, including: . the prices at which others offer competitive services; . the ability and willingness of our competitors to finance customers' projects on favorable terms; 16

. the ability of our customers to perform the services themselves; and . the extent of our competitors' responsiveness to customer needs. We may not be able to compete effectively on these or other bases, and, as a result, our revenues or income may decline and harm our business. We must keep pace with rapid technological change, market conditions and industry developments to maintain or grow our revenues. The market for wireless and other network system design, deployment and management services is characterized by rapid change and technological improvements. Our future success will depend in part on our ability to enhance our current service offerings to keep pace with technological developments and to address increasingly sophisticated customer needs. We may not be successful in developing and marketing in a timely manner service offerings that respond to the technological advances by others and our services may not adequately or competitively address the needs of the changing marketplace. If we are not successful in responding in a timely manner to technological change, market conditions and industry developments, our revenues may decline and our business may be harmed. Our business operations could be significantly disrupted if we lose members of our management team. Our success depends to a significant degree upon the continued contributions of our executive officers, both individually and as a group. See "Management-- Directors, Executive Officers and Key Employees", incorporated by reference into our Annual Report on Form 10-K for the year ended December 31, 2000, for a listing of such executive officers. Our future performance will be substantially dependent on our ability to retain and motivate them. We may not be successful in our efforts to identify, acquire or integrate acquisitions. Our failure to manage risks associated with acquisitions could harm our business. An important component of our business strategy is to expand our presence in new or existing markets by acquiring additional businesses. During 2000, we acquired seven businesses. We are almost continuously engaged in discussions or negotiations regarding the acquisition of businesses or strategic investments in businesses, some potentially material in relation to our size. We may not be able to identify, acquire or profitably manage additional businesses or integrate successfully any acquired businesses without substantial expense, delay or other operational or financial problems. Acquisitions involve a number of risks, including: . diversion of management's attention; . difficulty in integrating and absorbing the acquired business, its employees, corporate culture, managerial systems and processes and services; . failure to retain key personnel and employee turnover; . customer dissatisfaction or performance problems with an acquired firm; . assumption of unknown liabilities; and . other unanticipated events or circumstances. We may not be successful in our efforts to integrate international acquisitions. A key component of our business model is to expand our operations into international markets. We have accomplished this through the establishment of offices in Brazil, India and Mexico, among others, and through our recent acquisition of Questus Ltd. in the United Kingdom and Telia Academy and Telia Contracting in Sweden. International acquisitions pose a challenge to our business, as we must integrate operations despite differences in culture, language and legal environments. To date, we have limited experience with international acquisitions and face certain related risks, including: . difficulties in staffing, managing and integrating international operations due to language, cultural or other factors; 17

. different, or conflicting regulatory or legal requirements; . foreign currency fluctuations; and . distractions of significant management time and attention. Our failure to address these risks could inhibit or preclude our efforts to pursue international acquisitions. We have recently expanded our operations internationally. Our failure to effectively manage our international operations could harm our business. From January 1, 2000 through March 31, 2001, we were engaged on projects in 54 countries, and we currently have operations overseas, including offices in Mexico, the United Kingdom, India, Brazil and Sweden. For the quarter ended March 31, 2001, international operations accounted for approximately 33% of our total revenues. We believe that the percentage of total revenues attributable to international operations will continue to be significant. We intend to expand our existing international operations and may enter additional international markets, which will require significant management attention and financial resources and could adversely affect our operating margins and earnings. In order to expand our international operations, we will need to hire additional personnel and develop relationships with potential international customers. To the extent that we are unable to do so on a timely basis, our growth in international markets would be limited, and our business would be harmed. Our international business operations are subject to a number of material risks, including, but not limited to: . difficulties in building and managing foreign operations; . difficulties in enforcing agreements and collecting receivables through foreign legal systems and addressing other legal issues; . longer payment cycles; . taxation issues; . fluctuations in the value of foreign currencies; and . unexpected domestic and international regulatory, economic or political changes. To date, we have encountered each of the risks set forth above in our international operations. If we are unable to expand and manage our international operations effectively, our business may be harmed. Fluctuations in the value of foreign currencies could harm our profitability. The majority of our international sales are currently denominated in U.S. dollars. As a result of some of our recent acquisitions as well as the growth of our foreign operations, an increasing portion of our international sales are denominated in foreign currencies. Fluctuations in the value of the U.S. dollar and foreign currencies may make our services more expensive than local service offerings. This could make our service offerings less competitive than local service offerings, which could harm our business. To date, our experience with this foreign currency risk has predominately related to the Brazilian real and Mexican peso. We do not currently engage in currency hedging activities to limit the risks of exchange rate fluctuations. Therefore, fluctuations in the value of foreign currencies could have a negative impact on the profitability of our global operations, which would harm our business and financial results. We may encounter potential costs or claims resulting from project performance. Our engagements often involve large scale, highly complex projects. Our performance on such projects frequently depends upon our ability to manage our relationship with our customers, effectively administer the project and deploy appropriate resources, both our own personnel and third party contractors, in a timely manner. Many of our engagements involve projects that are significant to the operations of our customers' businesses. Our failure to meet a customer's expectations in the planning or implementation of a project or the 18

failure of our personnel or third party contractors to meet project completion deadlines could damage our reputation, result in termination of our engagement and adversely affect our ability to attract new business. We frequently undertake projects in which we guarantee performance based upon defined operating specifications or guaranteed delivery dates. Unsatisfactory performance or unanticipated difficulties or delays in completing such projects may result in a direct reduction in payments to us, or payment of damages by us, which could harm our business. As of March 31, 2001, executive officers and directors and their affiliates controlled 55% of our outstanding common stock and as a result are able to exercise control over all matters requiring stockholder approval. As of March 31, 2001, executive officers and directors and their affiliates beneficially owned, in the aggregate, approximately 55% of our outstanding common stock. In particular, as of March 31, 2001, our Chairman, Massih Tayebi, and our Chief Executive Officer, Masood K. Tayebi, beneficially owned, in the aggregate, approximately 39% of the outstanding common stock. In addition, other members of the Tayebi family owned, as of March 31, 2001, in the aggregate, approximately 11% of our outstanding common stock. As a result, these stockholders are able to exercise control over matters requiring stockholder approval, such as the election of directors and approval of significant corporate transactions, which may have the effect of delaying or preventing a third party from acquiring control over us. These transactions may include those that other stockholders deem to be in their best interests and in which those other stockholders might otherwise receive a premium for their shares over their current prices. For further information regarding our stock ownership, see "Security Ownership of Certain Beneficial Owners and Management" incorporated by reference into our Annual Report on Form 10-K for the year ended December 31, 2000. Our stock price may be particularly volatile because of the industry of our business. The stock market in general has recently experienced extreme price and volume fluctuations. In addition, the market prices of securities of technology and telecom companies have been extremely volatile, and have experienced fluctuations that have often been unrelated to or disproportionate to the operating performance of such companies. These broad market fluctuations could adversely affect the price of our common stock. For further information regarding recent stock trends, see "Market for Registrant's Common Equity and Related Stockholder Matters" in our Annual Report on Form 10-K for the year ended December 31, 2000. Provisions in our charter documents and Delaware law may make it difficult for a third party to acquire our company and could depress our common stock. Delaware corporate law and our certificate of incorporation and bylaws contain provisions that could delay, defer or prevent a change in control of our company or our management. These provisions could also discourage proxy contests and make it more difficult for our stockholders to elect directors and take other corporate actions. As a result, these provisions could limit the price that investors are willing to pay in the future for shares of our common stock. These provisions include: . authorizing the board of directors to issue additional preferred stock; . prohibiting cumulative voting in the election of directors; . limiting the persons who may call special meetings of stockholders; . prohibiting stockholder action by written consent; and . establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on by stockholders at stockholder meetings. We are also subject to certain provisions of Delaware law which could delay, deter or prevent us from entering into an acquisition, including Section 203 of the Delaware General Corporation Law, which prohibits a Delaware corporation from engaging in a business combination with an interested stockholder unless specific conditions are met. 19

Item 3. Quantitative and Qualitative Disclosures About Market Risk We are exposed to foreign currency risks due to both transactions and translations between a functional and reporting currency in our Mexican, Brazilian and United Kingdom subsidiaries. We currently do not hedge any of these risks in our foreign subsidiaries because (1) cash flows from foreign operations in Mexico are generally reinvested locally in Mexico, (2) foreign operations in Brazil are minimal, (3) the British pound sterling is relatively stable against the U.S. dollar, and (4) we do not believe that to do so is justified by the current exposure and the cost at this time. We are exposed to the impact of foreign currency fluctuations due to the operations of and intercompany transactions with our consolidated foreign subsidiaries. While these intercompany balances are eliminated in consolidation, exchange rate changes do affect consolidated earnings. The following table sets forth amounts owed to our U.S. operations from our Mexican, Brazilian, and United Kingdom subsidiaries at March 31, 2000 and 2001 (denominated in U.S. dollars, in millions): 2000 2001 ---- ---- Mexico........................................................... $5.2 $7.7 Brazil........................................................... $1.2 $1.3 United Kingdom................................................... $0.1 $5.3 The potential foreign currency translation losses from a hypothetical 10% adverse change in the exchange rates from the intercompany balances at March 31, 2000 and 2001 are as follows (in millions): 2000 2001 ---- ---- Mexico........................................................... $0.5 $0.8 Brazil........................................................... $0.1 $0.1 United Kingdom................................................... $ -- $0.5 In addition, we estimate that a 10% change in foreign exchange rates would impact reported operating profit (loss) for the three months ended March 31, 2000 and 2001 by approximately $0.3 million and $0.3 million, respectively. This was estimated using a 10% deterioration factor to the average monthly exchange rates applied to net income or loss for each of the subsidiaries in the respective period. We do not use derivative financial instruments, derivative commodity instruments or other market risk sensitive instruments, positions or transactions in any material fashion. Accordingly, management believes that it is not subject to any material risks arising from changes in interest rates, foreign currency exchange rates, commodity prices, equity prices or other market changes that affect market risk sensitive instruments. As of March 31, 2001, $27.0 million was outstanding under our $100 million line of credit with a group of financial institutions. The credit facility is due in February 2004 and bears interest, at our discretion, at either (i) the greater of the bank prime rate and the Federal Funds Rate plus .5%, plus a margin of 1.25%, the base rate margin, or (ii) at the London Interbank Offering Rate (LIBOR) plus 2.25%, the LIBOR rate margin. Beginning in the third quarter of 2001, the base rate margin and the LIBOR rate margin will be determined based on certain financial ratios as of the end of the most recently ended fiscal quarter which will result in margins ranging from .75% to 1.50% and 1.75% to 2.50%, respectively. The credit facility is secured by substantially all of our assets. The credit agreement contains restrictive covenants, which, among other things, require maintenance of certain financial ratios. We do not utilize any derivative financial instruments to hedge the interest rate fluctuation as our balances under the credit facility are borrowed over the short term and we currently retain the ability to pay down amounts borrowed through our operational funds. A hypothetical 10% adverse change in the weighted average interest rate for the three months ended March 31, 2001 would have increased net loss for the period by approximately $0.1 million. 20

PART II. OTHER INFORMATION Item 1. Legal Proceedings In October 2000, we were notified that Norm Korey, a former employee who was terminated by us, has asserted that he is owed certain commissions and stock options and severance pay from us. We were served with a formal arbitration demand relating to the matter in January 2001, and anticipate that limited discovery will ensue. We believe the claims of Mr. Korey are without merit and intend to defend any lawsuit asserting such claims. From time to time, we may also become involved in various lawsuits and legal proceedings which arise in the ordinary course of business. However, litigation is subject to inherent uncertainties, and an adverse result in this or other matters may arise from time to time that may harm our business. Item 2. Changes in Securities Recent Sales of Unregistered Securities During the three months ended March 31, 2001, we issued unregistered securities in the following transactions: On March 30, 2001, we issued an aggregate of 899,994 shares of common stock to two members of our board of directors. The shares were issued pursuant to Warrant Agreements, dated February 28, 1997 and February 1, 1998, between WFI and each of the two members of the board of directors. The exercise prices of $.93 and $1.58 were paid in exchange for 99,996 shares and 799,998 shares of our common stock, respectively. The issuance of the securities in connection with these warrant exercises was deemed to be exempt from registration under the Securities Act of 1933, as amended by virtue of Section 4(2) and/or Regulation D promulgated thereunder. The recipients represented their intentions to acquire the securities for investment purposes only and not with a view to the distribution thereof. Each of the recipients received adequate information about the Company and the Company reasonably believed that each of the recipients was an "Accredited Investor", as such term is defined in the Securities Act of 1933, as amended. Item 6. Exhibits and Reports on Form 8-K: (a). Exhibits: None. (b). Reports on Form 8-K: None. 21
