3.2 Purchase Price Adjustment Calculations.

3.2.1 Closing Adjustments; Interim Adjustments.

(a) Retained Working Capital.

(i) Closing Adjustments. Three (3) Business Days prior to the Closing Date, Seller shall deliver to Purchaser its good faith estimate of the Retained Working

Capital as of March 31, 2007 (the “Estimated Retained Working Capital Calculation”), which shall be based upon and reconciled to the Unaudited March Balance Sheet. Within two (2) Business Days following receipt of the Estimated Retained Working Capital Calculation, Purchaser may object in good faith to the Estimated Retained Working Capital Calculation by giving written notice to Seller setting forth in reasonable detail: (i) the specific amount to which Purchaser objects (the “Objection Amount”), (ii) the reasons for Purchaser’s objection (which shall be based on GAAP) and (iii) Purchaser’s proposed adjustments to Seller’s calculation (“Purchaser’s Estimate Objection”). If Purchaser fails to object to the Estimated Retained Working Capital Calculation within such two (2) Business Day period, Purchaser will be deemed to have conclusively agreed with and shall be bound by the Estimated Retained Working Capital Calculation for the purposes of Section 3.3.1(a)(i), and the Purchase Price will be adjusted as set forth in Section 3.3.1(a)(i) based on the Estimated Retained Working Capital Calculation. If Purchaser objects to the Estimated Retained Working Capital Calculation, Seller and Purchaser shall confer in good faith following Seller’s receipt of Purchaser’s Estimate Objection for the period up to the Closing (the “Estimate Resolution Period”) to attempt to reach agreement regarding such Objection Amount. If Seller and Purchaser reach agreement during the Estimate Resolution Period, the Purchase Price will be adjusted as set forth in Section 3.3.1(a)(i) based on the agreed upon Estimated Retained Working Capital Calculation. If Seller and Purchaser are unable to reach agreement during the Estimate Resolution Period with respect to the Objection Amount, (a) the Purchase Price will be adjusted as set forth in Section 3.3.1(a)(i) based on the Estimated Retained Working Capital Calculation, excluding the Objection Amount adjusted to reflect the results of the parties’ good faith negotiations, at the Closing and (b) Seller and Purchaser will resolve any outstanding disagreement regarding the Objection Amount following the Closing in accordance with the procedures set forth in Section 3.2.1(a)(ii) and Section 3.2.2(a), as applicable.

(ii) Interim Adjustments. No later than seven (7) Business Days following the Closing Date, Purchaser shall notify Seller of any good faith objection to the Estimated Retained Working Capital Calculation by giving written notice to Seller setting forth in reasonable detail: (i) the specific amount to which Purchaser objects (the “Interim Objection Amount”), (ii) the reasons for Purchaser’s objections (which shall be based on GAAP) and (iii) Purchaser’s proposed adjustments to Seller’s calculation (“Purchaser’s Interim Estimate Objection”). If Purchaser delivers to Seller a timely Purchaser’s Interim Estimate Objection, such Purchaser’s Interim Estimate Objection shall be deemed to supersede any Objection Amount not resolved during the Estimate Resolution Period. Seller and Purchaser shall confer in good faith for ten (10) Business Days following the earlier of the date on which Purchaser delivers a Purchaser’s Interim Estimate Objection to Seller and the seventh (7^th) Business Day following the Closing Date (the “Interim Period”) to attempt to reach agreement regarding the Purchaser’s Interim Estimate Objection or any Objection Amount not resolved during the Estimate Resolution Period, as applicable. If Seller and Purchaser reach agreement during the Interim Period, the Purchase Price will be adjusted as set forth in Section 3.3.1(a)(ii) based on the agreed upon Estimated Retained Working Capital Calculation. If Seller and Purchaser are unable to reach agreement during the Interim Period with respect to any such Interim Objection Amount or Objection Amount, as applicable, Seller and Purchaser will resolve any outstanding disagreement regarding such Interim Objection Amount or Objection Amount, as applicable, in accordance with the procedures set forth in Section 3.2.2(a).

If Purchaser fails to object to the 2006 EBITDA Calculation within such five (5) Business Day period, Purchaser will be deemed to have conclusively agreed with and shall be bound by the 2006 EBITDA Calculation for the purposes of Section 3.3.1(b), and the Purchase Price will be adjusted as set forth in Section 3.3.1(b) based on the 2006 EBITDA Calculation. If Purchaser objects to the 2006 EBITDA Calculation, Seller and Purchaser shall confer in good faith following Seller’s receipt of Purchaser’s Estimate EBITDA Objection for the Estimate Resolution Period to attempt to reach agreement regarding the disputed amount (the “Disputed Amount”). If Seller and Purchaser reach agreement during the Estimate Resolution Period, the Purchase Price will be adjusted as set forth in Section 3.3.1 based on the agreed upon 2006 EBITDA Calculation. If Seller and Purchaser are unable to reach agreement during the Estimate Resolution Period with respect to the Disputed Amount, (a) the Purchase Price will be adjusted based on the agreed upon 2006 EBITDA Calculation and (b) Seller and Purchaser will resolve any outstanding disagreement regarding the Disputed Amount following the Closing in accordance with the procedures set forth in Section 3.2.2(b).

3.2.2 Post-Closing Adjustment.

If Purchaser fails to object to the Retained Working Capital Calculation within such thirty (30) day period, Purchaser will be deemed to have conclusively agreed with and shall be bound by the Retained Working Capital Calculation for the purposes of Section 3.3.2(a), and the Purchase Price will be adjusted as set forth in Section 3.3.2(a) based on the Retained Working Capital Calculation. If Purchaser objects to the Retained Working Capital Calculation, Seller and Purchaser shall confer in good faith for a period of up to fifteen (15) days following Seller’s receipt of Purchaser’s Objection (the “Resolution Period”) to attempt to reach agreement regarding such calculation. If Seller and Purchaser are unable to reach agreement during the Resolution Period, then Seller and Purchaser shall confer in good faith for up to five (5) days to agree on a nationally recognized independent accounting firm, which shall not be the regular accounting firm of Purchaser or Seller (the “Resolution Firm”) to resolve the outstanding disagreement in accordance with the procedures set forth below; provided, however, that if the Parties cannot agree on a Resolution Firm, then each of Seller and Purchaser will select a nationally recognized accounting firm and the two firms selected by Seller and Purchaser will select the Resolution Firm. The Resolution Firm will review the Retained Working Capital Calculation and Purchaser’s Objection and make a final

written determination of the Retained Working Capital Calculation, which determination shall be conclusive and binding on Seller and Purchaser. The Resolution Firm’s engagement shall be solely limited to determining the Retained Working Capital Calculation and, if applicable, the Final 2006 EBITDA Calculation.

If Purchaser fails to object to the Final 2006 EBITDA Calculation within such thirty (30) day period, Purchaser will be deemed to have conclusively agreed with and shall be bound by the Final 2006 EBITDA Calculation for the purposes of Section 3.3.2(b), and the Purchase Price will be adjusted as set forth in Section 3.3.2(b) based on the Final 2006 EBITDA Calculation. If Purchaser objects to the Final 2006 EBITDA Calculation, Seller and Purchaser shall confer in good faith for a period of up to fifteen (15) days following Seller’s receipt of Purchaser’s EBITDA Objection (the “EBITDA Resolution Period”) to attempt to reach agreement regarding such calculation. If Seller and Purchaser are unable to reach agreement during the EBITDA Resolution Period, then Seller and Purchaser shall confer in good faith for up to five (5) days to agree on a Resolution Firm to resolve the outstanding disagreement in accordance with the procedures set forth below; provided, however, that if the Parties cannot agree on a Resolution Firm, then each of Seller and Purchaser will select a nationally recognized accounting firm and the two firms selected by Seller and Purchaser will select the Resolution Firm. The Resolution Firm will review the Final 2006 EBITDA Calculation and Purchaser’s EBITDA Objection and make a final written determination of the Final 2006 EBITDA Calculation, which determination shall be conclusive and binding on Seller and Purchaser. The Resolution Firm’s engagement shall be solely limited to determining the Final 2006 EBITDA Calculation and, if applicable, the Retained Working Capital Calculation.

(c) The Parties agree that, in the event there are disputes under both Section 3.2.2(a) and Section 3.2.2(b), (i) one firm will be designated as the Resolution Firm to resolve the disputes under both Section 3.2.2(a) and Section 3.2.2(b) and (ii) they will instruct the Resolution Firm to issue its determination of such disputes at the same time.

Each of the Parties will furnish all information required for any application or other filing to be made pursuant to the rules and regulations of any applicable Law in connection with the transactions contemplated by this Agreement. The Parties shall cooperate with each other and will each use their reasonable best efforts to: (1) ensure that all of the Retained Accounts Receivable and Transferred Unbilled Accounts Receivable, as applicable, are collected in a timely manner, including obtaining purchase orders and any approvals necessary to ensure payment from the applicable client; (2) keep each Party reasonably informed regarding the progress towards milestones under Customer Agreements, Dual Use Contracts and Subcontractor Agreements, as applicable, related to unbilled Retained Accounts Receivable and Transferred Unbilled Accounts Receivables, as applicable, and shall cooperate with each other in invoicing unbilled Retained Accounts Receivable and Transferred Unbilled Accounts Receivables, as applicable, as promptly as possible; and (3) provide the necessary data to the invoicing Party necessary to prepare the invoice and shall agree, upon the reasonable request of the other Party, to follow up with the appropriate client personnel on any applicable approval processes and payment status.

6.4 Third Party Consents; Dual-Use Contracts.

6.4.1 Seller will use commercially reasonable efforts to obtain, in a form and on terms reasonably acceptable to Purchaser, such written consents, assignments, waivers and authorizations or other certificates from third parties and give such notices to third parties, in each case that are required to consummate the transactions provided for herein and to keep in effect and avoid the breach, violation or termination of any Transferred Agreement (each, an “Assignment Consent”). If any Assignment Consent, other than an Assignment Consent for a Contract set forth on Schedule 8.1.12 or a Related Document set forth on Schedule 8.1.14(iii) as to which Purchaser has not waived the applicable closing condition, is not received on or before the Closing Date with respect to any Transferred Agreement, (i) Seller shall cooperate with Purchaser in any reasonable arrangement designed to provide Purchaser with all of the benefits of such Transferred Agreement as if the Assignment Consent had been obtained, including by granting subleases and establishing subcontracting arrangements, and (ii) upon receipt of such Assignment Consent, such Transferred Agreement shall be assigned to Purchaser.

6.4.2 Prior to Closing, (a) Seller shall establish subcontracting arrangements with, and grant subleases to, as applicable, Purchaser to provide Purchaser with all of the benefits relating to the Business under the Dual-Use Contracts listed on Schedule 8.1.14(i) (the “Seller Subcontracting Agreements”), (b) Seller shall transfer the Dual-Use Contracts listed on Schedule 8.1.14(ii) to Purchaser and Purchaser shall establish subcontracting arrangements with, and grant subleases to, as applicable, Seller to provide Seller with all of the benefits other than those

relating to the Business under such transferred Dual-Use Contracts listed on Schedule 8.1.14(ii) (the “Purchaser Subcontracting Agreements” and together with the Seller Subcontracting Agreements, the “Subcontracting Agreements”) and (c) Seller shall transfer the purchase orders, contract supplements, work orders and similar engagement documents under the Dual-Use Contracts listed on Schedule 8.1.14(iii) to Purchaser (the “Related Documents”). If any Dual-Use Contracts are not subcontracted or subleased, as the case may be, to Purchaser on or before the Closing Date, Seller shall cooperate with Purchaser in any reasonable arrangement designed to provide Purchaser with all of the benefits relating to the Business under the such Dual-Use Contracts. If any Dual-Use Contracts transferred to Purchaser are not subcontracted or subleased, as the case may be, to Seller on or before the Closing Date, Purchaser shall cooperate with Seller in any reasonable arrangement designed to provide Seller with all of the benefits other than those relating to the Business under the such Dual-Use Contracts. From and after the Closing Date, the Parties will use commercially reasonable efforts and shall cooperate with each other in any reasonable arrangement designed to obtain any further written consents, assignments, waivers and authorizations or other certificates from third parties and give such notices to third parties, in each case that are required for the Parties to enter into direct arrangements with the third-parties to the Dual-Use Contracts to provide, with respect to the Purchaser, all of the benefits of the Dual-Use Contracts relating to the Business, and, with respect to the Seller, all of the benefits of the Dual-Use Contracts other than those relating to the Business.

6.5 Employee Matters.

6.5.1 Prior to the Closing Date, Purchaser shall offer employment to the Business Employees listed on Schedule 6.5.1 and consulting or services engagements to the Business’ Contractors listed on Schedule 6.5.1. Effective on the later of the Closing Date or the date on which each Transferred Employee or Contractor commences employment or engagement by Purchaser, as the case may be, Purchaser shall provide, or shall cause to be provided to, such Transferred Employee or Contractor, as the case may be, compensation, employee benefits, title, duties and responsibilities, location for performance of duties, credit for years of service, and terms and conditions of employment or consulting engagement that are substantially similar, in the aggregate, as Purchaser provides to similarly-situated employees or contractors of Purchaser. Effective on the later of the Closing Date or the date on which a Transferred Employee commences employment by Purchaser, to the extent permitted by Law and applicable tax qualification requirements, and subject to any generally applicable break in service or similar rule, and the approval of any insurance carrier, third party provider or the like with reasonable best efforts of Purchaser, such Transferred Employee shall receive credit for his service with Seller prior to the Closing for purposes of eligibility to participate and vesting (but not for benefit accrual purposes) under the employee benefit plans and arrangements of Purchaser, but only to the extent such service was given credit under the Seller Benefit Plans. Notwithstanding any of the foregoing to the contrary, none of the provisions contained herein shall operate to duplicate any benefit provided to any Transferred Employee or the funding of any such benefit. Subject to the approval of any insurance carrier, third party provider or the like with reasonable best efforts of Purchaser, Purchaser will also cause all (A) pre-existing conditions and proof of insurability provisions, for all conditions that each Transferred Employee and his covered dependents have as of the later of the Closing Date or the date on which such Transferred Employee commences employment by Purchaser, and (B) waiting periods under each plan that would otherwise be

applicable to newly hired employees to be waived in the case of clause (A) or clause (B) with respect to such Transferred Employee to the same extent waived or satisfied under Seller’s Employee Benefit Plans; provided, however, that nothing in this sentence shall limit the ability of Purchaser from amending or entering into new or different employee benefit plans or arrangements provided such plans or arrangements treat the Transferred Employees or Contractors, as the case may be, in a substantially similar manner as employees or contractors of Purchaser are treated.

6.5.2 Nothing in this Section 6.5 is intended to alter the terms and conditions or character of any existing employment relationship between Seller and any Business Employee.

6.5.3 Purchaser shall not take any action which would subject Seller, or any of its Subsidiaries, to liability under the WARN Act and the regulations promulgated thereunder or under California Labor Code Sections 1400-1408 or the equivalent statutes under and other applicable state Law.

6.5.4 No provision of this Section 6.5 shall create any third party beneficiary or other rights in any employee or former employee (including any beneficiary or dependent thereof) of Seller in respect of continued employment (or resumed employment) with Purchaser and no provision of this Section 6.5 shall create any such rights in any such Persons in respect of any benefits that may be provided, directly or indirectly, under any employee benefit plan or any plan or arrangement which may be established by Purchaser or any of its Affiliates.

6.6 Transfer Taxes; Expenses. All transfer Taxes (not including income Taxes) incurred in connection with the transactions contemplated by this Agreement (and the cost of preparing any Tax Returns related to transfer Taxes) shall be paid by Seller. All real property, personal property, ad valorem or other similar Taxes (not including income Taxes) levied with respect to the Transferred Assets or the Business for a taxable period which includes the Closing Date shall be apportioned between Purchaser and Seller based on the number of days included in such period through and including the Closing Date and the number of days included in such period after the Closing Date. To the extent that any portion of a pro-rated Tax or allocated transfer Tax is paid or required by Law to be paid by one Party hereto but required by the foregoing to be borne by another Party hereto, such other Party shall pay or reimburse the Tax-paying Party for the proper portion of the Tax required to be so borne upon notice from the Tax-paying Party of the amount of such Tax required to be paid or reimbursed. Each Party shall timely and duly cause to be filed all Tax Returns and other documentation with respect to all Taxes subject to this Section 6.6 that are required by Law to be filed by such Party, and shall pay to the relevant Governmental Entity all such Taxes that are required to be paid by such Party (subject to such reimbursement as provided for herein).

6.7 Financing. Purchaser covenants that, at Closing and in any event no later than the Termination Date, Purchaser will have sufficient funds to consummate the transactions contemplated by the Transaction Documents. Purchaser acknowledges and agrees that Purchaser’s obligation to consummate the transactions contemplated by this Agreement are not contingent upon the consummation of any financing transaction.

6.8 No Solicitation or Negotiations. Seller shall not nor shall it authorize or permit any of its officers, directors or employees, investment bankers, financial advisors, attorneys, accountants or other advisors, agents or representatives (collectively, “Representatives”) to, directly or indirectly, (a) solicit, initiate, encourage or facilitate the submission of, an offer to acquire the Business or any material portion thereof, or greater than a majority of the Transferred Assets, pursuant to a merger, consolidation, asset purchase, stock purchase or other business combination transaction (an “Alternative Proposal”), or (b) participate in any discussions or negotiations regarding, or furnish to any Person any non-public information with respect to, or take any other action to facilitate knowingly the making of any inquiry or any proposal that constitutes, or would reasonably be expected to lead to, any Alternative Proposal. In the event that Seller receives a written or oral inquiry expressing interest in an Alternative Proposal from any third party, Seller shall immediately, by electronic mail, notify Purchaser in writing of such inquiry.

6.9 Non-Solicitation/Covenant Not to Hire.

6.9.1 Covenant Not to Hire. Unless the Parties otherwise mutually agree in writing, Seller and its Affiliates agree that they will not, and will not permit their Affiliates to, prior to the second anniversary of the Closing Date, in any manner, directly or indirectly or by assisting others, (a) hire or attempt to hire, on any of their behalves or on behalf of any other Person, any Transferred Employee, or (b) otherwise encourage any Transferred Employee to leave the employ of Purchaser; provided, however, that this Section 6.9.1 shall not apply to Transferred Employees who have ceased to remain in service to Purchaser, as employees or consultants or otherwise, for ninety (90) or more days.

6.9.3 Injunctive Relief. The Parties hereby agree that any remedy at law for any breach of the provisions contained in this Section 6.9 may be inadequate and that the non-breaching Party will be entitled to seek injunctive relief in addition to any other remedy such Party might have under this Agreement.

6.10 Broker’s Fees. Seller and Purchaser each agree to pay and hold the other Party harmless with respect to any fee due to any broker, finder or investment banker engaged by such Party in connection with the transactions contemplated by this Agreement.

6.13.2 Seller’s Access. On and after the Closing Date, Purchaser will afford promptly to Seller and its accountants, attorneys, agents and representatives full and complete access to their properties, books, records, documents, employees, directors and auditors to the extent reasonably necessary or appropriate to permit Seller to (a) determine any matter relating to Seller’s rights and obligations hereunder or to any period ending on or before the Closing Date, (b) complete and/or initiate any and all financial audits necessary or appropriate for Seller’s business, operations and financial reporting purposes, and (c) respond to, prepare for, or defend itself against any third-party or governmental investigation, inquiry, action, suit, proceeding, claim or threatened or actual legal or arbitral proceedings, including any and all stockholder derivative and/or class action litigation, including In re Xxx.xxx, Inc.

party or governmental investigation, inquiry, action, suit, proceeding, claim or threatened or actual legal proceeding or arbitration.

While the restrictions contained in this Section 6.14 are considered by the Parties to be reasonable in all the circumstances for the protection of the interests of Purchaser, it is recognized that restrictions of the nature in question may fail for technical reasons and, accordingly, it is hereby agreed and declared that if any of such restrictions shall be adjudged to be void but would be valid if part of the wording thereof were deleted or the periods thereof reduced or the range of activities or area dealt with thereby reduced in scope, the said restriction shall apply with such modifications as may be necessary to make it valid and effective. The Parties hereby agree that any remedy at Law for any of breach by Seller of any of the provisions contained in this Section 6.14 may be inadequate and that Purchaser will be entitled to seek injunctive relief in addition to any other remedy Purchaser may have under this Agreement.

ARTICLE 11

Indemnification

11.1 Indemnification Obligations of Seller. Seller will indemnify, defend and hold harmless the Purchaser Indemnified Parties from, against and in respect of any and all Damages to the extent arising out of or relating to:

11.1.1 any breach of the representations and warranties made by Seller in Section 4.1 (Organization), Section 4.2 (Authorization), Section 4.5.3 (Financial Information),

Section 4.8.2 (Transferred Unbilled Accounts Receivable), Section 4.9 (Legal Proceedings), Section 4.12 (Tax Returns; Taxes), Section 4.13 (Seller Benefit Plans) and Section 4.14 (Employees and Contractors);

11.1.2 any breach of any covenant, agreement or undertaking made by Seller in this Agreement or any Seller Ancillary Documents, if Seller fails to cure the breach within a reasonable period of time (not to exceed thirty (30) days) following receipt of written notice of the breach from Purchaser;

11.1.3 any Excluded Assets or Excluded Liabilities;

11.1.4 any fraud or willful misconduct of Seller in connection with this Agreement or any Seller Ancillary Documents;

11.1.5 any (i) Taxes with respect to the Transferred Assets or the Business with respect to any taxable period or portion of a taxable period ending on or before the Closing Date; (ii) Taxes of Seller or any Affiliate of Seller other than Taxes described in clause (i) of this Section 11.1.5; and (iii) any Taxes or fees described in Section 6.6 of this Agreement (amounts described in clauses (i), (ii) or (iii) being referred to hereinafter as “Indemnified Taxes”); or

11.2.2 any breach of any covenant, agreement or undertaking made by Purchaser in this Agreement or in any Purchaser Ancillary Documents, if Purchaser fails to cure the breach within a reasonable period of time (not to exceed thirty (30) days) following receipt of written notice of the breach from Seller;

11.2.5 the operation of the Business by Purchaser after the Closing Date; or

11.2.6 any of Purchaser’s obligations under any of the Seller Subcontracting Agreements.

11.3 Indemnification Procedure for Third Party Claims. Promptly after receipt by an Indemnified Party of notice by a third party (including any Governmental Entity) of any

complaint or the commencement of any audit, investigation, action or proceeding with respect to which such Indemnified Party may be entitled to receive payment from the other Party for any Damages, such Indemnified Party will notify Purchaser or Seller, as the case may be (the “Indemnifying Party”), promptly following the Indemnified Party’s receipt of such complaint or of notice of the commencement of such audit, investigation, action or proceeding; provided, however, that the failure to so notify the Indemnifying Party will relieve the Indemnifying Party from liability under this Agreement with respect to such claim only if, and only to the extent that, such failure to notify the Indemnifying Party results in the forfeiture by the Indemnifying Party of rights and defenses otherwise available to the Indemnifying Party with respect to such claim. The Indemnifying Party will have the right, within ten (10) days after written notice delivered to the Indemnified Party, to assume full responsibility for any Damages (as the case may be) resulting from such audit, investigation, action or proceeding, to assume the defense of such audit, investigation, action or proceeding, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of the fees and disbursements of such counsel. If, however, the Indemnifying Party declines or fails to assume the defense of the audit, investigation, action or proceeding on the terms provided above or to employ counsel reasonably satisfactory to the Indemnified Party, in either case within such ten (10)-day period, then the Indemnifying Party will pay the reasonable fees and disbursements of counsel for the Indemnified Party as incurred. In any audit, investigation, action or proceeding for which the Indemnifying Party has assumed the defense, the Indemnified Party will have the right to participate in such matter and to retain its own counsel at the Indemnified Party’s own expense. The Indemnifying Party will at all times use reasonable efforts to keep the Indemnified Party reasonably apprised of the status of the defense of any matter the defense of which the Indemnifying Party has assumed and to cooperate in good faith with the Indemnified Party with respect to the defense of any such matter.

11.4 Settlement or Compromise. No Indemnified Party may settle or compromise any claim or consent to the entry of any judgment with respect to which indemnification is being sought hereunder without the prior written consent of the Indemnifying Party, unless (a) the Indemnifying Party fails to assume and maintain the defense of such claim pursuant to Section 11.3 or (b) such settlement, compromise or consent includes an unconditional release of the Indemnifying Party and its officers, directors, employees and Affiliates from all Liability arising out of such claim. An Indemnifying Party may not, without the prior written consent of the Indemnified Party, settle or compromise any claim or consent to the entry of any judgment with respect to which indemnification is being sought hereunder unless such settlement, compromise or consent (x) includes an unconditional release of the Indemnified Party and its officers, directors, employees and Affiliates from all Liability arising out of such claim, (y) does not contain any admission or statement suggesting any wrongdoing or Liability on behalf of the Indemnified Party and (z) does not contain any equitable order, judgment or term which in any manner affects, restrains or interferes with the business of the Indemnified Party or any of the Indemnified Party’s Affiliates.

11.5 Payment. If an Indemnified Party claims a right to payment pursuant to this Agreement, such Indemnified Party will send written notice of such claim to the appropriate Indemnifying Party. Such notice will specify the basis for such claim. As promptly as possible after the Indemnified Party has given such notice, such Indemnified Party and the appropriate Indemnifying Party will establish the merits and amount of such claim (by mutual agreement,

litigation, arbitration or otherwise) and, within five (5) Business Days of the final determination of the merits and amount of such claim, the Indemnifying Party will pay to the Indemnified Party immediately available funds in an amount equal to such claim as determined hereunder; provided, however, that if at any time prior to the Escrow Release Date (a) Purchaser and Seller have not entered into the Escrow Agreement as provided in Section 11.9.5 and (b) Seller is the Indemnifying Party and the Note is outstanding, then Purchaser shall offset the outstanding principal and accrued and unpaid interest of the Note as of such time with an amount equal to the Damages that are subject of the claim; provided further, however, that the aggregate amount of any offset under the Note, together with the aggregate amount of any and all prior offset amounts under the Note, shall not exceed One Million Dollars ($1,000,000). If Purchaser shall be entitled to offset the principal amount of the Note pursuant to this Section 11.5, the Note shall be automatically amended in accordance with its terms to reflect the revised outstanding principal amounts under the Note. Subject to the limitations set forth in this Section 11.5, if all of the outstanding principal amount and accrued and unpaid interest of the Note equal an amount less than the amount of the Damages subject to the claim under this Section 11.5, then all remaining principal amount and interest under the Note shall be offset and Seller shall pay to Purchaser in immediately available funds an amount equal to the balance of the claim in accordance with this Section 11.5.

11.6 Claims Period. Any and all claims and causes of action for indemnification under this Article 11 must be made prior to the termination of the applicable claims period set forth in this Section 11.6.

11.6.1 The representations and warranties of Seller in Section 4.12 (Tax Returns; Taxes) shall survive until thirty (30) days following expiration of the applicable statute or similar period of limitations, as will claims for indemnification for Indemnified Taxes as defined in Section 11.1.5;

11.6.2 The representations and warranties of Seller contained in Section 4.1 (Organization), Section 4.2 (Authorization), Section 4.5.3 (Financial Information), Section 4.8.2 (Transferred Unbilled Accounts Receivable), Section 4.9 (Legal Proceedings), Section 4.13 (Seller Benefit Plans) and Section 4.14 (Employees and Contractors) shall survive until the Escrow Release Date;

11.6.3 The representations and warranties of Purchaser contained in Section 5.1 (Organization), Section 5.2 (Authorization) and Section 5.4 (Legal Proceedings) shall survive until the Escrow Release Date; and

11.6.4 The claims for indemnification under Sections 11.1.2, 11.1.3, 11.1.4 and 11.1.6 and Sections 11.2.2, 11.2.3, 11.2.4, 11.2.5 and 11.2.6 shall survive the Closing Date.

Notwithstanding the foregoing, if, prior to the close of business on the last day of the applicable claims period, an Indemnifying Party is properly notified of a claim for indemnity hereunder and such claim has not been finally resolved or disposed of at such date, such claim will continue to survive and will remain a basis for indemnity hereunder until such claim is finally resolved or disposed of in accordance with the terms hereof.

11.7 Liability Thresholds. Notwithstanding anything in this Article 11 to the contrary, neither Purchaser on the one hand, nor Seller on the other hand, shall be liable to the other under Section 11.1 or Section 11.2, respectively, unless the total amount of Damages with respect to all claims against Purchaser or Seller, as applicable, exceeds One Hundred Thousand Dollars ($100,000) (the “Basket Amount”), and once the amount of Damages against Purchaser or Seller, as applicable, in respect to such claims exceeds the Basket Amount, Purchaser or Seller, as applicable, shall be entitled to recover the entire amount of Damages so determined; provided, however, that this limitation shall not apply to Damages resulting from or arising out of fraud, intentional misrepresentation or an intentional breach of warranty on the part of Seller, nor shall it apply to Damages for breaches of the representations and warranties contained in Section 4.12 (Tax Returns; Taxes) or for Indemnified Taxes as defined in Section 11.1.5. Amounts paid by a Party pursuant to Section 3.3 (Purchase Price Adjustments) will not be considered damages subject to, and will not be counted toward, the Basket Amount specified in this Section 11.7.

11.8 Liability Cap. Notwithstanding anything to the contrary contained in this Agreement, the maximum aggregate amount to which the Purchaser Indemnified Parties on the one hand, or the Seller Indemnified Parties on the other hand, may be entitled with respect to claims under Section 11.1.1 or Section 11.2.1 shall be One Million Dollars ($1,000,000); provided, however, that this limitation shall not apply to Damages resulting from or arising out of breaches of the representations and warranties made by Seller in Section 4.9 (Legal Proceedings) or Section 4.12 (Tax Returns; Taxes), fraud, intentional misrepresentation or an intentional breach of warranty on the part of Seller. Subject to the applicable dollar cap set forth in Section 11.5 and this Section 11.8, the amount of any Damages payable by Seller shall be offset against the outstanding principal amount and accrued and unpaid interest of the Note in accordance with Section 11.5. Amounts paid by a Party pursuant to Section 3.3 (Purchase Price Adjustments) will not be considered Damages subject to, and will not be counted toward, the liability cap specified in this Section 11.8.

11.9 Other Provisions Concerning Indemnification.

11.9.1 Neither Party will be liable to the other Party for any indirect, consequential, incidental, special or punitive damages or similar items in connection with this Agreement; provided, however, that this limitation shall not apply to claims for Damages resulting from or arising out of fraud or willful misconduct on the part of either Party. Notwithstanding the foregoing, nothing in this Section 11.9 is intended to limit the indemnity obligations of any Party pursuant to Article 11 with respect to third party claims. Amounts paid by a Party pursuant to Section 3.3 (Purchase Price Adjustments) will not be subject to the liability exclusion specified in this Section 11.9.

11.9.2 The right of each Party to indemnification, reimbursement or other remedy based upon any representations, warranties, covenants and obligations of the other Party herein shall not be affected by any investigation conducted with respect to, or any knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, by such Party with respect to the accuracy or inaccuracy of or compliance with any representation, warranty, covenant or obligation.

11.9.3 Any payment made by Purchaser, Seller or any of their respective Affiliates pursuant to this Article 11 shall, to the extent permissible under applicable Law, be treated as an adjustment to Purchase Price for all relevant Tax purposes.

11.9.4 To the extent that any provisions of this Article 11 conflict with any provisions in the Employee Leasing Agreement that relate to indemnification rights or obligations, the provisions of the Employee Leasing Agreement shall control.

11.9.5 If, at any time prior to January 31, 2008 (the “Escrow Release Date”) Purchaser is required under the terms of the Note to prepay all or a portion thereof, and, as a result of such prepayment, the outstanding balance of the Note would be less than One Million Dollars ($1,000,000) minus any amounts against which Purchaser has exercised its set off rights under the Note pursuant to this Section 11 (the “Escrow Amount”), simultaneously with such prepayment (i) Purchaser and Seller shall enter into the Escrow Agreement in substantially the form attached hereto as Exhibit C with the Escrow Agent and (ii) Purchaser shall deliver to the Escrow Agent by wire transfer of immediately available funds a portion of such prepayment in an amount equal to the Escrow Amount, which delivery shall be deemed to constitute a payment of the Escrow Amount to Seller. The Escrow Amount shall serve as an escrow for indemnification claims pursuant to Section 11.1. Any amount remaining in the Escrow Account (as defined in the Escrow Agreement) on the Escrow Release Date and not reserved in connection with claims for indemnification pursuant to Section 11.1 and the Escrow Agreement shall be disbursed to Seller at such time.

11.10 Remedy. Except for any equitable relief, including injunctive relief or specific performance, to which any Party hereto may be entitled, from and after the Closing, the indemnification rights provided in this Article 11 will be the sole and exclusive remedy of each Party hereto and each of their respective Affiliates and their officers, directors, employees, stockholders, agents or representatives with respect to this Agreement, and no Party shall be entitled to rescission of the Agreement; provided, however, the foregoing will in no way limit the rights of an Indemnified Party for any fraud or intentional misconduct by a Party in connection with this Agreement, the documents executed in connection herewith or the transactions contemplated hereby.

THIS INSTRUMENT AND THE RIGHTS AND OBLIGATIONS EVIDENCED HEREBY ARE SUBORDINATE IN THE MANNER AND TO THE EXTENT SET FORTH IN THAT CERTAIN SUBORDINATION AGREEMENT (AS AMENDED, FROM TIME TO TIME, THE “SUBORDINATION AGREEMENT”) DATED AS OF JUNE ___, 2007, AMONG BANK OF AMERICA, N.A., LCC INTERNATIONAL, INC. AND CERTAIN OF ITS SUBSIDIARIES AND WIRELESS FACILITIES, INC., AND THE HOLDER OF THIS NOTE, BY ITS ACCEPTANCE HEREOF, IRREVOCABLY AGREES TO BE BOUND BY THE PROVISIONS OF THE SUBORDINATION AGREEMENT.

SUBORDINATED PROMISSORY NOTE


$22,000,000		June ___, 2007

FOR VALUE RECEIVED, LCC International, Inc., a Delaware corporation (the “Maker”), promises to pay to Wireless Facilities, Inc., a Delaware corporation (the “Holder”), at Bridge Pointe Corporate Center, 0000 Xxxxxxxx Xxxx, Xxx Xxxxx, Xxxxxxxxxx 00000, or at such other place as the Holder of this Note may from time to time designate, on June ___, 2010 (the “Maturity Date”), the principal amount of Twenty Two Million Dollars ($22,000,000) (which amount may be increased or decreased from time to time without further consent of the Maker and the Holder pursuant to the terms of the Purchase Agreement, as defined below, as reflected on Schedule 1 attached hereto), or such lesser amount as may be outstanding under this Note on the Maturity Date, together with interest on the unpaid principal amount hereof from the date hereof, until paid in full, said interest to be computed and paid as set forth below. For purposes of clarification, (i) any increase to the principal amount under this Note pursuant to the terms of the Purchase Agreement shall be deemed to be outstanding as of the date hereof and interest shall accrue on such principal amount from the date of this Note and (ii) any decrease to the principal amount under this Note pursuant to the terms of the Purchase Agreement shall be deemed to be made as of the date hereof and the interest under this Note shall be calculated accordingly. All payments hereunder shall be made in lawful money of the United States of America.

Interest on the unpaid principal amount hereof shall be computed on the basis of actual days elapsed over a 360-day year, at a floating rate of one-month LIBOR (LIBOR to reset on the first Business Day of each month) plus

(a) from the date of this Note to and including June 30, 2007, 4% per annum,

(b) from July 1, 2007 to and including July 31, 2007, 5% per annum,

(d) from September 1, 2007 to and including September 30, 2007, 7% per annum,

(e) from October 1, 2007 to and including December 31, 2007, 8% per annum,

(f) from January 1, 2008 to and including June 30, 2008, 9% per annum,

(g) from July 1, 2008 to and including December 31, 2008, 10% per annum,

(h) from January 1, 2009 to and including June 30, 2009, 11% per annum,

(i) from July 1, 2009 to and including December 31, 2009, 12% per annum,

(j) from January 1, 2010 to (but not including) the Maturity Date, 13% per annum, and

(k) if the principal amount and interest accrued thereon under this Note is not paid in full on or prior to the Maturity Date, an increase of 1% per annum to the then applicable rate determined hereunder for each six month period beginning on July 1 and January 1 of each year, until the Note is paid in full.

For purposes of this Note, “LIBOR” means, for any interest period described above, the rate per annum equal to the British Bankers Association LIBOR Rate (“BBA LIBOR”), as published by Reuters at approximately 11:00 a.m., London time, two Business Days prior to the commencement of such interest period, for dollar deposits (for delivery on the first day of such interest period) with a term most closely approximating such interest period.

Subject to the terms of the Subordination Agreement, interest payments shall be due (i) with respect to the period commencing on the Closing Date and ending on June 30, 2007, in arrears on the fifth (5^th) Business Day following the date on which the Maker shall have delivered to the lenders the financial statements for, and the Compliance Certificate (as defined in the Credit Agreement (as defined below)) with respect to, calendar quarter ended June 30, 2007 required to be delivered under the Credit Agreement and (ii) with respect to each calendar quarter commencing on or after July 1, 2007, in arrears on the fifth (5^th) Business Day following the date on which the Maker shall have delivered to the Lenders the financial statements for, and the Compliance Certificate with respect to, such calendar quarter required to be delivered under the Credit Agreement (each an “Interest Payment Date”). All accrued and unpaid interest shall be paid in full on the Maturity Date.

In the event the Maker fails to pay interest under this Note within five (5) Business Days following the date on which the Maker is required to deliver quarterly or annual financial statements, as applicable, under the Credit Agreement (i) with respect to any two (2) consecutive Interest Payment Dates during the period commencing on July 1, 2007 and ending on June 30, 2008 or (ii) with respect to any one Interest Payment Date occurring after July 1, 2008, the Holder shall be entitled, by delivery of written notice to the Maker within forty-five (45) days following such Interest Payment Date (the “Election Notice”), to convert the total amount of interest due on such Interest Payment Date, or in the case of the foregoing clause (i), such two (2) Interest Payment Dates (the “Total Unpaid Interest”) into a number of shares of the Maker’s Class A Common Stock, par value $0.01 per share (the “Maker Common Stock”) equal to the quotient obtained by dividing (a) the Total Unpaid Interest on the date of the Election Notice

by (b) the average of the closing prices of the Maker Common Stock as reported on the NASDAQ Global Market or other national stock exchange for the last ten (10) trading day period ending two (2) days prior to the delivery of the Election Notice in accordance with the terms hereof (the “Common Stock Price”). No fractional shares will be issued upon the conversion of the Total Unpaid Interest. In lieu of any fractional shares to which Holder would otherwise be entitled, Maker shall pay Holder in cash that amount of the unconverted Total Unpaid Interest equal to such fraction multiplied by the Common Stock Price. Maker shall issue and deliver to Holder within seven (7) Business Days after the date of the Election Notice a certificate for the number of shares of Maker Common Stock to which Holder is entitled upon such conversion of the Total Unpaid Interest, including a check payable to Holder for any cash amounts payable in lieu of fractional shares as described above. Holder’s Election Notice shall contain such representations as the Maker shall reasonably request to satisfy itself that the issuance of such shares to the Holder is exempt from registration under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (the “1933 Act”) and applicable state securities laws. Notwithstanding the foregoing, in the event Maker is subject to NASDAQ Marketplace Rule 4350(i) (the “Marketplace Rule”) at the time of such issuance, Maker shall not issue any shares which shall result in the aggregate number of shares of Maker Common Stock issued pursuant to this Note to exceed of 19.999% of the shares of Maker Common Stock outstanding on the date hereof (taking into account any stock splits or reverse stock splits in the Maker Common Stock occurring after the date hereof) without first obtaining the required stockholder consent pursuant to the Marketplace Rule; provided, however, that Maker shall use its commercially reasonable best efforts to obtain any required stockholder approval as soon as possible following receipt of any Election Notice. Any shares of Maker Common Stock issued pursuant to this paragraph, including any Maker Common Stock issued as a dividend or other distribution with respect to, or in exchange for, or in replacement of such Maker Common Stock, shall be subject to registration for resale under the 1933 Act upon the terms and conditions set forth in Exhibit A hereto.

Subject to the terms of the Subordination Agreement, the unpaid principal amount of, and any accrued interest on, this Note must be prepaid:

(a) with the one hundred percent (100%) of the Net Cash Proceeds received by the Maker or its Subsidiaries (as defined in the Credit Agreement), until this Note is paid in full, in respect of any issuance of equity security for cash (other than pursuant to employee benefit plans) or debt financing that is subordinated to the obligations of the Maker and its Subsidiaries under the Credit Agreement, other than (i) any debt financing under the Credit Agreement, (ii) a refinancing of existing debt financing or (iii) debt financing for working capital of one or more Foreign Subsidiaries; and

(b) upon a Change of Control (as defined below) of the Maker, provided that no event of default under the Credit Agreement (other than an event of default as a result of such Change of Control) has occurred and is continuing.

Any prepayment, including under subsections (a) or (b) above, shall be without premium or penalty.

Subject to the Subordination Agreement, the unpaid principal amount of, and any accrued interest on, this Note may be prepaid in whole or in part at any time or times without premium or penalty.

For purposes of this Note, a “Change of Control” means (a) an event or series of events by which any “person” or “group” (as such terms are used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (the “1934 Act”) but excluding any employee benefit plan of such person or its subsidiaries, and any person or entity acting in its capacity as trustee, agent or other fiduciary or administrator of any such plan) becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Securities Exchange Act of 1934, except that a person or group shall be deemed to have “beneficial ownership” of all Equity Interests that such person or group has the right to acquire, whether such right is exercisable immediately or only after the passage of time (such right, an “option right”)), directly or indirectly, of fifty-one percent (51%) of the Equity Interests of the Maker entitled to vote for members of the board of directors or equivalent governing body of the Maker on a fully diluted basis (and taking into account all such securities that such person or group has the right to acquire pursuant to any option right) or (b) the sale or transfer of all or substantially all of the assets of the Maker, whether in a single transaction or a series of related transactions.

For purposes of this Note, the following defined terms shall have the meanings provided for such terms in that certain Amended and Restated Credit Agreement (as amended, modified, restated, supplemented or refinanced from time to time, the “Credit Agreement”), dated as of May 29, 2007, among the Maker, certain Subsidiaries of the Maker, the lenders party thereto and Bank of America, N.A. as administrative agent, as in effect on May 29, 2007: “Net Cash Proceeds,” “Foreign Subsidiaries” and “Equity Interests.”

Each prepayment shall be applied first to the payment of all interest and other amounts accrued hereunder on the date of any such prepayment, and the balance of any such prepayment shall be applied to the principal amount hereof. No prepayment shall entitle any person to be subrogated to the rights of the Holder unless and until this Note has been paid in full.

This Note is made and delivered pursuant to and in accordance with the terms and conditions of that certain Asset Purchase Agreement (the “Purchase Agreement”), dated as of May 29, 2007, by and between the Maker and the Holder and is subject to the terms and conditions of the Purchase Agreement, which are, by this reference incorporated herein and made a part hereof. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Purchase Agreement.

So long as any principal or interest payments are outstanding hereunder, the Maker agrees to provide to the Holder of this Note, at such Holder’s election, the following:

(a) A copy of each quarterly and annual Compliance Certificate delivered by the Maker to Bank of America, N.A. pursuant to the requirements of the Credit Agreement;

(b) Notice of any default or event of default given or received under the Credit Agreement; and

(c) In the event that the Maker ceases to be a public company, (i) a consolidated and consolidating balance sheet of the Maker and its Subsidiaries as of the end of each fiscal year thereafter, and the related consolidated and consolidating statements of income or operations, shareholders’ equity and cash flows for such fiscal year, and (ii) a consolidated balance sheet of the Maker and its Subsidiaries as of the end of each of the first three fiscal quarters of each fiscal year thereafter, and the related consolidated statements of income or operations, shareholders’ equity and cash flows for such fiscal year.

The occurrence of any one or more of the following events with respect to the Maker shall constitute an event of default (“Event of Default”) hereunder:

(a) Failure to pay, when due, the principal or any interest payable hereunder, and continuance of such failure for fifteen (15) business days after the Holder notifies the Maker thereof in writing; provided, however, that the exercise by the Maker in good faith of its right of setoff pursuant to this Note, whether or not ultimately determined to be justified, shall not constitute an Event of Default;

(b) The admission by the Maker in writing of its inability to pay its debts as such debts become due, or the making by the Maker of any general assignment for the benefit of creditors;

(c) The commencement by the Maker of any case, proceeding, or other action seeking reorganization, arrangement, adjustment, liquidation, dissolution, or composition of it or its debts under any law relating to bankruptcy, insolvency, or reorganization, or relief of debtors, or seeking appointment of a receiver, trustee, custodian, or other similar official for it or for all or any substantial part of its property; or

(d) The commencement of any case, proceeding, or other action against the Maker seeking to have any order for relief entered against the Maker as debtor, or seeking reorganization, arrangement, adjustment, liquidation, dissolution, or composition of the Maker or its debts under any law relating to bankruptcy, insolvency, reorganization, or relief of debtors, or seeking appointment of a receiver, trustee, custodian, or other similar official for the Maker or for all or any substantial part of the property of the Maker, and (i) the Maker shall, by any act or omission, indicate its consent to, approval of, or acquiescence in such case, proceeding, or action, or (ii) such case, proceeding, or action results in the entry of an order for relief which is not fully stayed within seven (7) Business Days after the entry thereof, or (iii) such case, proceeding, or action remains undismissed for a period of sixty (60) days or more or is dismissed or suspended only pursuant to Xxxxxxx 000 xx xxx Xxxxxx Xxxxxx Bankruptcy Code or any corresponding provision of any future United States bankruptcy law.

Subject to the subordination provisions of the Subordination Agreement, upon the occurrence of any such Event of Default hereunder, the entire principal amount hereof, and all accrued and unpaid interest thereon, shall, at the option of the Holder, be accelerated, and shall thereupon become immediately due and payable and the Holder shall be entitled to exercise any

one or more of the rights and remedies provided by applicable law; provided that in the case of clauses (b), (c) and (d) above, such acceleration shall occur automatically without demand or notice. Failure to exercise said option or to pursue such other remedies shall not constitute a waiver of such option or such other remedies or of the right to exercise any of the same in the event of any subsequent Event of Default hereunder.

The Holder of this Note, by acceptance hereof, agrees that the Note and the indebtedness represented hereby, and the payment of principal of and all present and future interest hereon, is expressly subordinated and junior in right of payment to the prior payment in full of the Senior Debt (as defined in the Subordination Agreement).

The Holder of this Note may at any time assign all (but not less than all) of its rights and obligations under this Note to an assignee; provided, however, that prior to June ___, 2008, the Holder may assign its rights and obligations under this Note to an assignee only upon (a) a consolidation or merger of the Holder with and into another entity or (b) a sale by the Holder of all or substantially all of its assets. Subject to the preceding sentence, this Note will be binding in all respects upon the Maker and inure to the benefit of the Holder and its successors and assigns.

Any payment on this Note coming due on a Saturday, a Sunday, or a day which is a legal holiday in the place at which a payment is to be made hereunder shall be made on the next succeeding day which is a Business Day, and any such extension of the time of payment shall be included in the computation of interest hereunder.

Except as explicitly provided herein, the Maker hereby waives presentment, protest, demand, notice of dishonor, and all other notices, and all defenses and pleas on the grounds of any extension or extensions of the time of payments or the due dates of this Note, in whole or in part, before or after maturity, with or without notice.

No single or partial exercise by the Holder of any right hereunder shall preclude any other or further exercise thereof or the exercise of any other rights. No delay or omission on the part of the Holder in exercising any right hereunder shall operate as a waiver of such right or of any other right under this Note.

This Note and all agreements between the Maker and the Holder relating hereto are hereby expressly limited so that in no contingency or event whatsoever, whether by reason of acceleration or otherwise, shall the amount paid or agreed to be paid to the Holder for the use, forbearance or detention of money hereunder exceed the maximum amount permissible under applicable law. If from any circumstance whatsoever fulfillment of any provision hereof, at the time performance of such provision shall be due, shall involve transcending the limit of validity prescribed by law, then, ipso facto, the obligation to be fulfilled shall be reduced to the limit of such validity, and if from any such circumstance the Holder shall ever receive interest, or anything which might be deemed interest under applicable law, which would exceed the highest lawful rate, such amount which would be excessive interest shall be applied to the reduction of the principal amount owing on account of this Note and not to the payment of interest, or if such excessive interest exceeds the unpaid balance of principal of this Note, such excess shall be

refunded to the Maker. All sums paid or agreed to be paid to the Holder for the use, forbearance or detention of the indebtedness of the Maker to the Holder shall, to the extent permitted by applicable law, be deemed to be amortized, prorated, allocated and spread throughout the full term of such indebtedness until payment in full so that the actual rate of interest on account of such indebtedness is uniform throughout the term thereof. The terms and provisions of this paragraph shall control and supersede every other provision of this Note and all other agreements between the Maker and the Holder.

Except as otherwise provided in Exhibit A, this Note shall be governed by the laws of the State of New York, without regard to the conflicts of law principles that would result in the application of any law other than the law of the State of New York.

Except as otherwise provided in this Note, including without limitation in Exhibit A, (a) all notices, communications and deliveries required or made pursuant to this Note shall be made in accordance with the procedures specified in Section 12.1 of the Purchase Agreement and (b) any dispute arising out of or relating to this Note shall be resolved in accordance with the procedures specified in Section 12.7 of the Purchase Agreement.

IN WITNESS WHEREOF, the Maker has executed this Note as of the date first set forth above.

The Company shall use reasonable best efforts to pursue the Issuer Filing until the NASD issues a letter confirming that it does not object to the terms of the offering contemplated by the Registration Statement.

all financial and other records, all filings of the Company with the SEC, and all other corporate documents and properties of the Company as may be reasonably necessary for the purpose of such review, and cause the Company’s officers, directors, employees and independent accountants, within a reasonable time period, to supply all such information reasonably requested by the Investors or any such representative, advisor or underwriter in connection with such Registration Statement (including, without limitation, in response to all questions and other inquiries reasonably made or submitted by any of them), prior to and from time to time after the filing and effectiveness of the Registration Statement for the sole purpose of enabling the Investors and such representatives, advisors and underwriters and their respective accountants and attorneys to conduct initial and ongoing due diligence with respect to the Company and the accuracy of such Registration Statement.

(b) Except as otherwise provided in the Note, the Company shall not disclose material nonpublic information to the Investors, or to advisors to or representatives of the Investors, unless prior to disclosure of such information the Company identifies such information as being material nonpublic information and provides the Investors, such advisors and representatives with the opportunity to accept or refuse to accept such material nonpublic information for review and any Investor wishing to obtain such information enters into an appropriate confidentiality agreement with the Company with respect thereto.

Section 18. 5. Obligations of the Investors.

Section 19.

At least ten (10) Business Days prior to the first anticipated filing date of the Registration Statement, the Company shall notify each Investor of the information the Company requires from such Investor if such Investor elects to have any of the Registrable Securities included in the Registration Statement. An Investor shall provide such information to the Company at least two (2) Business Days prior to the first anticipated filing date of such Registration Statement if such Investor elects to have any of the Registrable Securities included in the Registration Statement.

Section 21. 6. Indemnification.

Section 22. (a) Indemnification by the Company. To the fullest extent permitted by law, the Company will indemnify and hold harmless each Investor and its officers, directors, members, partners, employees, attorneys and agents, successors and assigns, and each other Person, if any, who controls such Investor within the meaning of the 1933 Act or Section 20 of the 1934 Act (and their officers, directors, partners, members and employees), against any losses, claims, damages, expenses, costs (including reasonable attorney fees) or liabilities, joint or several, to which they may become subject under the 1933 Act or otherwise, insofar as such losses, claims, damages, expenses, costs or liabilities (or actions in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof; (ii) any blue sky application or other document executed by the Company specifically for that purpose or based upon written information furnished by the Company filed in any state or other jurisdiction in order to qualify any or all of the Registrable Securities under the securities laws thereof (any such application, document or information herein called a “Blue Sky Application”); (iii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; (iv) any violation by the Company or its agents of any rule or regulation promulgated under the 1933 Act applicable to the Company or its agents and relating to action or inaction required of the Company in connection with such registration; or (v) any failure to register or qualify the Registrable Securities included in any such Registration in any state where the Company or its agents has affirmatively undertaken or agreed in writing that the Company will undertake such registration or qualification on an Investor’s behalf and will reimburse such Investor, and each such officer, director or member and each such controlling Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action, which reimbursement shall be made as such expenses are incurred if such Investor has delivered a written undertaking to the Company to repay such reimbursement promptly following any final determination that such Investor was not entitled thereto; provided, however, that the Company will not be liable in any such case if and to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Investor or any such controlling Person in writing specifically for use in such Registration Statement or Prospectus.

Section 23. (b) Indemnification by the Investors. Each Investor agrees, severally but not jointly, to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors, officers, employees, stockholders and each Person who controls the Company (within the meaning of the 0000 Xxx) against any losses, claims, damages, liabilities and reasonable expense (including reasonable attorney fees) resulting from any untrue statement of a material fact contained in the Registration Statement, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof or any omission of a material fact required to be stated in the Registration Statement or Prospectus or preliminary prospectus or amendment or supplement thereto or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, to

the extent, but only to the extent that such untrue statement or omission is contained in any information furnished in writing by such Investor to the Company specifically for inclusion in such Registration Statement or Prospectus or amendment or supplement thereto. In no event shall the liability of an Investor be greater in amount than the dollar amount of the net proceeds received by such Investor upon the sale of the Registrable Securities giving rise to such indemnification obligation.

Section 24. (c) Conduct of Indemnification Proceedings. Any Person entitled to indemnification hereunder shall (i) give prompt notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided that any Person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such Person unless (a) the indemnifying party has agreed to pay such fees or expenses, or (b) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such Person or (c) in the reasonable judgment of any such Person, based upon written advice of its counsel, a conflict of interest exists between such person and the indemnifying party with respect to such claims (in which case, if the Person notifies the indemnifying party in writing that such Person 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 such claim on behalf of such Person); and provided, further, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the extent that such failure to give notice shall materially adversely affect the indemnifying party in the defense of any such claim or litigation. It is understood that the indemnifying party shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for all such indemnified parties. No indemnifying party will, except with the consent of the indemnified party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation, does not impose any injunction or similar restriction on such indemnified party and does not include a statement as to or an admission of fault, liability, culpability or failure to act with respect to any law by an indemnified party.

Section 25. (d) Contribution. If for any reason the indemnification provided for in the preceding paragraphs (a) and (b) is unavailable to an indemnified party or insufficient to hold it harmless, other than as expressly specified therein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such indemnifying, party or indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement

or omission. The parties hereto agree that it would not be just and equitable if contribution pursuant to this section were determined by pro rata allocation or by any other method of allocation that does not take into account the foregoing equitable considerations. No Person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the 1933 Act shall be entitled to contribution from any Person not guilty of such fraudulent misrepresentation. In no event shall the contribution obligation of a holder of Registrable Securities be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such holder in connection with any claim relating to this Section 6 and the amount of any damages such holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission) received by it upon the sale of the Registrable Securities giving rise to such contribution obligation.

Section 26. (e) The obligations of the Company and the Investors under this Section 6 shall survive the completion of any offering of Registrable Securities in a Registration Statement filed pursuant to the terms of this Exhibit A.

This Exhibit A may be amended, modified or waived only by a writing signed by the Company and the Required Investors; provided that if any such amendment, modification or waiver would adversely affect in any material respect any Investor or group of Investors who have comparable rights under this Exhibit A disproportionately to the other Investors having such comparable rights, such amendment, modification, or waiver shall also require the written consent of the Investor(s) so adversely affected.

Section 29. (b) Notices. All notices and other communications provided for or permitted hereunder shall be made as set forth in Section 12.1 of the Purchase Agreement.

Section 30. (c) Assignments and Transfers by Investors. The provisions of this Exhibit A shall be binding upon and inure to the benefit of the Investors and their respective successors and assigns. An Investor may transfer or assign, in whole or from time to time in part, to one or more Persons its rights hereunder in connection with the transfer of Registrable Securities by such Investor to such Person, provided that (i) after such assignment or transfer, such Person holds at least twenty-five percent (25%) of the Registrable Securities, (ii) such Investor complies with all laws applicable thereto and provides written notice of assignment to the Company promptly after such assignment is effected and (iii) the transferee agrees in writing to be bound by this Exhibit A as if it were a party hereto; provided, however, that the limitation set forth in subsection (c)(i) shall not apply to assignments or transfers to a subsidiary, parent or affiliate of the Investor.

This Exhibit A may not be assigned by the Company (whether by operation of law or otherwise) without the prior written consent of the Required Investors, provided, however, that the Company may assign its rights and delegate its duties hereunder to any surviving or successor

corporation in connection with a merger or consolidation of the Company with another corporation, or a sale, transfer or other disposition of all or substantially all of the Company’s assets to another corporation, without the prior written consent of the Required Investors, after notice duly given by the Company to each Investor.

Section 32. (e) Benefits of this Exhibit A. The terms and conditions of this Exhibit A shall inure to the benefit of and be binding upon the respective permitted successors and assigns of the parties.

Section 34. (g) Severability. Any provision of this Exhibit A that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof but shall be interpreted as if it were written so as to be enforceable to the maximum extent permitted by applicable law, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by applicable law, the parties hereby waive any provision of law which renders any provisions hereof prohibited or unenforceable in any respect.

Section 35. (h) Further Assurances. The parties shall execute and deliver all such further instruments and documents and take all such other actions as may reasonably be required to carry out the transactions contemplated hereby and to evidence the fulfillment of the agreements herein contained.

EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS EXHIBIT A AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.

(l) Obligations of Investors. The Company acknowledges that the obligations of each Investor under this Exhibit A are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance of the obligations of any other Investor under this Exhibit A. The decision of each Investor to enter into to this Exhibit A has been made by such Investor independently of any other Investor.

Schedule 1

Plan of Distribution

The selling stockholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling shares of common stock or interests in shares of common stock received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common stock or interests in shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

The selling stockholders may use any one or more of the following methods when disposing of shares or interests therein:

- ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

- block trades in which the broker-dealer will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction;

- purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

- an exchange distribution in accordance with the rules of the applicable exchange;

- privately negotiated transactions;

- short sales effected after the date the registration statement of which this Prospectus is a part is declared effective by the SEC;

- through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

- broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share; and

- a combination of any such methods of sale.

The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under an amendment or supplement to this prospectus under Rule 424(b)(3) or other applicable provision of the 1933 Act amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as

selling stockholders under this prospectus. The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

In connection with the sale of our common stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of our common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The aggregate proceeds to the selling stockholders from the sale of the common stock offered by them will be the purchase price of the common stock less discounts or commissions if any. Each of the selling stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from this offering.

The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the 1933 Act, provided that they meet the criteria and conform to the requirements of that rule.

The selling stockholders and any underwriters, broker-dealers or agents that participate in the sale of the common stock or interests therein may be “underwriters” within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the 1933 Act. Selling stockholders who are “underwriters” within the meaning of Section 2(11) of the 1933 Act will be subject to the prospectus delivery requirements of the Securities Act.

To the extent required, the shares of our common stock to be sold, the names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

In order to comply with the securities laws of some states, if applicable, the common stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common stock may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the 1934 Act may apply to sales of shares in the market and to the activities of the selling stockholders and their affiliates. In addition, the Company has advised each Selling Stockholder that the Commission currently takes the position that coverage of short sales “against the box” prior to the effective date of the registration statement of which this prospectus is a part would be a violation of Section 5 of the Securities Act, as described in Item 65, Section A, of the Manual of Publicly Available Telephone Interpretations, dated July 1997, compiled by the Office of Chief Counsel, Division of Corporate Finance. Further, we will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

We have agreed to indemnify the selling stockholders against liabilities, including liabilities under the 1933 Actand state securities laws, relating to the registration of the shares offered by this prospectus.

We have agreed with the selling stockholders to keep the registration statement of which this prospectus constitutes a part effective until the earlier of (1) such time as all of the shares covered by this prospectus have been disposed of pursuant to and in accordance with the registration statement or (2) the date on which the shares may be sold pursuant to Rule 144(k) of the Securities Act.

payment thereof) is invalid, unenforceable or avoidable, or that any Lien in favor of the Senior Agent or any Senior Lender in any of the Collateral is invalid, unenforceable, unperfected or avoidable, or is or should be subordinated to the interests of any Person.

(b) No Liens by Junior Noteholder. Until the Senior Debt shall be Paid in Full, the Junior Noteholder shall not seek to obtain, and shall not take, accept, obtain or have, any Lien in any asset or property of any Loan Party or any other Person as security for the Junior Note, or any part thereof, and, if and to the extent that any such Lien at any time exists in favor of the Junior Noteholder, such Liens are hereby subordinated to all Liens now or hereafter existing, for the benefit of or in favor of the Senior Lenders or any of their Affiliates or their successors or assigns granted or given by any Loan Party or any of its or their Affiliates, successors or assigns to secure the Senior Debt, or any part thereof, notwithstanding the date or order of attachment, creation, effectiveness or perfection of any of the foregoing or the provision of any applicable law or otherwise. The Junior Noteholder represents that, as of the date hereof, the Junior Noteholder has not taken or accepted any Lien in any asset or property of any Loan Party or any other Person to secure the Junior Note.

Section 4. Exercise of Remedies. The Junior Noteholder shall not take any Enforcement Action with respect to any Junior Debt until 180 days after the Senior Debt has been Paid in Full. If the Junior Noteholder initiates any Enforcement Action in violation of the terms of this Agreement, the Senior Agent may intervene and interpose the agreement of the Junior Noteholder contained herein as a defense thereto and shall be entitled to specific performance of the terms hereof.

Section 5. Turnover of Payments. If any payment, distribution or security (except for payments permitted under Section 2(b) hereof) or any proceeds of thereof, shall be collected or received by the Junior Noteholder in respect of the Junior Note in contravention of any of the terms of this Agreement, then the Junior Noteholder will hold such payment, distribution or security in trust for the benefit of the Senior Lenders and will forthwith deliver such payment, distribution, security or proceeds to the Senior Agent to be applied to the Senior Debt. If, at any time after Payment in Full of the Senior Debt, any payments of the Senior Debt must be disgorged by the holders thereof for any reason (including, without limitation, the bankruptcy of any Loan Party), this Agreement and the relative rights and priorities set forth herein shall be reinstated as to all such disgorged payments as though such payments had not been made and the Junior Noteholder shall immediately pay over all payments received with respect to the Junior Debt (to the extent that such payments would have been prohibited hereunder) to the Senior Agent to be applied to the applicable Senior Debt.

Section 6. Waivers and Agreements of Junior Noteholder. The Junior Noteholder hereby waives any defense based on the adequacy of a remedy at law or equity which might be asserted as a bar to the remedy of specific performance of the terms of this Agreement in any action brought therefor by the Senior Lenders.

Section 7. Bankruptcy or Other Proceeding. If there shall occur any Proceeding (a) the Senior Lenders shall be entitled to receive Payment in Full of the Senior Debt before the Junior Noteholder shall be entitled to receive any payment or distribution, whether in cash, securities or other property, in respect of any amounts due with respect to the Junior Debt at the time outstanding, and (b) any payment or distribution, whether in cash, securities or other property payable or deliverable in respect of the amounts due under or with respect to the Junior Debt shall be paid or delivered, to the extent of the unpaid balance of the Senior Debt, directly to the Senior Agent. In the event of any proceedings in connection with a Proceeding, the Senior Agent and the Senior Lenders shall be entitled to rely upon this Agreement, which the parties acknowledge is enforceable in accordance with its terms upon the

occurrence of any Proceeding, and shall have the right to prove, in addition to their claims on account of the Senior Debt, their claims hereunder in any such proceeding, so as to establish their rights hereunder and to receive directly from any receiver, trustee or other court officer or custodian’ distributions of any sort which would otherwise be payable on account of the Junior Debt.

Section 8. Amendments.

(a) Amendments to Loan Documents. The Junior Noteholder hereby agrees that nothing contained in this Agreement, the Junior Note or in any other agreement or instrument binding upon any of the parties hereto shall in any manner limit or restrict the ability of the Senior Agent or the Senior Lenders from increasing, or changing the terms of, the loans under the Loan Documents, or otherwise waiving, amending or modifying any of the terms and conditions of the Loan Documents, in such manner as the Senior Agent and the Senior Lenders and the Loan Parties shall mutually determine; provided, that the Senior Lenders shall not enter into any amendment of the Loan Documents that would extend the maturity date of all or any portion of the Senior Credit Agreement beyond November 30, 2012 without the prior written consent of the Junior Noteholder. The Junior Noteholder hereby further agrees that no waivers, amendments, modifications or compromises, or any other renewals, extensions, indulgences, releases of collateral or other accommodations granted by the Senior Agent or the Senior Lenders to the Loan Parties from time to time shall in any manner affect or impair the subordination established by this Agreement.

Nothing herein shall impair or prevent the Senior Agent or the Senior Lenders from exercising all rights and remedies otherwise permitted by applicable law upon default under the Loan Documents. The right of the Senior Agent or the Senior Lenders to enforce any provision of this Agreement shall not at any time in any way be prejudiced or impaired by any act or failure to act on the part of any Loan Party or by any act or failure to act by the Senior Agent or any Senior Lender or by any noncompliance by any Person with the terms, provisions and covenants of this Agreement, any of the Loan Documents or the Junior Note, regardless of any knowledge thereof which the Senior Agent or any Senior Lender may have or be otherwise charged with. Nothing herein shall impair, as between each Loan Party and the Junior Noteholder, the obligation of such Loan Party to pay to the Junior Noteholder the principal of and interest on the Junior Note as and when the same shall become due in accordance with its terms, subject, however, to the provisions of this Agreement.
