Closing; Purchase Price; Adjustments

The closing (the “Closing”) of the Contemplated Transactions shall take place at the offices of Squire, ▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇ L.L.P., ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇-▇▇▇▇, at 10:00 A.M. local time, on Friday, August 31, 2007 (provided that the conditions and deliveries referred to in Articles 6, 7 and 8 have been satisfied or waived on or prior to such date), or at such other time, date, place and manner that shall be mutually agreed upon by ATS and the Shareholders (the “Closing Date”). The Closing shall be effective as of the close of business on the Closing Date. At the Closing, each of the Shareholders shall sell, transfer, convey or assign and deliver to ATS; ATS shall purchase, acquire and accept from the Shareholders, the Shares, free and clear of any and all liens, claims, encumbrances or rights of any third party (and each of the Shareholders shall thereafter cease to have any rights as a shareholder in PMG other than any rights granted to the Shareholders pursuant to the terms of this Agreement and the other Transaction Documents).

2.2 Purchase Consideration.

As payment in full for all of the Shares, ATS shall pay, in accordance with the terms and conditions of this Agreement and the Shareholders’ Proportionate Interests, the amount equal to the Estimated Closing Purchase Price, adjusted in accordance with Section 2.3, plus the Promissory Notes, plus the amount of any “Contingent Consideration” (as defined below) (collectively, the “Purchase Consideration”).

(a) One-Day Notes; ATS Shares. At the Closing, ATS shall deliver to the Shareholders promissory notes (the “One-Day Notes”) in the form attached hereto as Exhibit C, payable to the Shareholders in proportion to the Shareholders’ Proportionate Interests, in an aggregate amount equal to ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇,

▇▇

▇▇▇▇▇ ▇▇▇▇▇▇▇, Fifty Thousand Dollars ($13,750,000) and the number of shares of ATS common stock, par value $0.0001, having a value of Five Hundred Thousand Dollars ($500,000.00) based on the ATS Share Value (the “ATS Shares”) (such aggregate Fourteen Million Two Hundred Fifty Thousand Dollars ($14,250,000), as the aggregate amount of the One-Day Notes is adjusted as of the Closing pursuant to Section 2.3(c), the “Estimated Closing Purchase Price”) less any deductions against the Closing Consideration made pursuant to Section 5.7(a), Section 5.8 and Section 5.20. ATS shall satisfy its payment obligations under the One-Day Notes by wire transfer, in immediately available funds, to the accounts designated by the Shareholders. The ATS Shares shall be distributed to the Shareholders in equal amounts (and not according to the Shareholders’ Proportionate Interests), and shall be titled in the names of “▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇ Trust dtd 4/27/04” and “▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇ Trust dtd 4/27/04.” In connection with the issuance of the ATS Shares, ATS and the Shareholders shall be required to execute and deliver a Registration Rights Agreement in the form attached hereto and incorporated herein as Exhibit D (the “Registration Rights Agreement”).

(b) Promissory Notes. At the Closing, ATS shall deliver the Promissory Notes to the Shareholders and ATS shall have the right to offset indemnification and other claims, pursuant to Section 2.3 and Article 9, against the Promissory Notes.

(c) Contingent Consideration. As an addition to and as part of the Purchase Consideration, ATS shall pay to the Shareholders, in accordance with the terms of this Section 2.2(c), up to an additional One-Million, Five-Hundred Thousand Dollars ($1,500,000) (the “Contingent Consideration”), as follows:

(i) If earned, the Contingent Consideration shall be payable in up to two installments, by wire transfer of immediately available funds to accounts designated by the Shareholders, in accordance with the Shareholders’ Proportionate Interests, within thirty (30) days after the first anniversary of the Closing Date and, if applicable, within thirty (30) days after the second anniversary of the Closing Date.

(ii) The Contingent Consideration will be payable based on ATS and its affiliates (including PMG and including the PMG Business Unit) recognizing revenues (determined in accordance with GAAP) from the Contingent Consideration Contract Base (A) during the first twelve-month period following the Closing Date (the “Initial Earn Out Period”) equal to more than $12.64 million (the “Initial Revenue Target”) and (B) during the second twelve-month period following the Closing Date (the “Second Earn Out Period”) equal to more than $14.44 million (the “Second Revenue Target”). To the extent revenues from the Contingent Consideration Contract Base during the Initial Earn Out Period exceed the Initial Revenue Target, the Shareholders will be paid Contingent Consideration equal to one-half of the incremental revenue up to a maximum of $1.5 million. In the event that less than $1.5 million is paid to the Shareholders pursuant to this Section 2.2(c) following the Initial Earn Out Period, to the extent revenues from the Contingent Consideration Contract Base during the Second Earn Out Period exceed the Second Revenue Target, the Shareholders will be paid Contingent Consideration equal to one-half of the incremental revenue, up to a maximum of $1.5 million less the amount of the payment in connection with the Initial Earn Out Period. (By way of example, if revenues from the Contingent Consideration Contract Base were $14.0 million during the Initial Earn Out Period, the payment in respect of the Initial Earn Out Period would be $680,000, and if revenues from the Contingent Consideration Contract Base were $18.0 million during the Second Earn Out Period, the payment in respect of the Second Earn Out Period would be $820,000.)

(iii) Following the Closing and during the Initial Earn Out Period and the Second Earn Out Period, ATS will use reasonable commercial efforts to pursue the contracts and proposals included in the Contingent Consideration Contract Base in accordance with PMG’s past practices and otherwise agrees that, during the Initial Earn Out Period and the Second Earn Out Period, it shall:

(A) not take any action intended to, or that could reasonably be expected to, result in a reduction of revenues from the Contingent Consideration Contract Base below that which would have been achieved if such action had not been taken;

(B) subject to Section 5.22(e) hereof with respect to the 8(a) Contract, maintain relations and goodwill with customers, employees, agents and others having business relationships with PMG as of the Closing Date;

(C) make reasonable commercial efforts to ensure that PMG (or the PMG Business Unit) maintains, in the ordinary course of business, the services of any technical and management employees who are essential to perform any contracts within the Contingent Consideration Contract Base and not transfer, assign, reassign or terminate without cause the employment of any such employees without the consent of the Shareholders; and

(D) not, without the prior consent of the Shareholders, which shall not be unreasonably withheld, terminate, transfer or reassign to any other Person, including ATS or any other ATS Affiliate, any contracts within the Contingent Consideration Contract Base.

In the event that a contract included in the Contingent Consideration Contract Base is sold or otherwise disposed of, ATS and the Shareholders shall agree on an amount to be credited toward the Initial Revenue Target or Second Revenue Target, as the case may be, in respect of such sale or other disposition, taking into account factors such as the amount received in respect of such contract, the margin reasonably anticipated to be earned on such contract, and the performance risks associated with such contract. In the event of a dispute as to the amount, if any, payable under the immediately foregoing sentence, the dispute shall be resolved in accordance with Section 2.4.

2.3 Closing Consideration and Adjustments.

(a) Closing Consideration. The “Closing Consideration” shall be the amount paid to the Shareholders at the Closing pursuant to Section 2.2(a).

(b) Calculation of PMG’s Estimated Closing Net Working Capital. Not less than two (2) Business Days prior to the Closing Date, the Shareholders shall deliver to ATS an estimated, unaudited balance sheet (the “Estimated Closing Balance Sheet”) of PMG as of the close of business on the Closing Date, together with all supporting documentation. The Estimated Closing Balance Sheet shall be prepared by PMG in a manner consistent with the balance sheet included in the Interim Financial Statements, except that the Estimated Closing Balance Sheet shall include a calculation of Net Working Capital.

(i) The Estimated Closing Purchase Price will be adjusted (A) downwards on a dollar-for-dollar basis to the extent that the Estimated Closing Net Working Capital is less than the lower end of the Base Net Working Capital Range and (B) upwards on a dollar-for-dollar basis to the extent that the Estimated Closing Net Working Capital exceeds the upper end of the Base Net Working Capital Range.

(ii) In the event that ATS decides not to make the Section 338(h)(10) Election contemplated by Section 5.16, ATS and the Shareholders shall mutually determine (not later than twenty (20) Business Days after the Closing Balance Sheet is finalized pursuant to Section 2.3(d) or Section 2.4), the amount of the adjustment required under Section 481 of the Code as a result of the conversion of PMG from the cash to the accrual method (the “Section 481 Adjustment”). To the extent the Section 481 Adjustment results in an increase in PMG’s Taxes for any taxable period ending on or before the Closing Date, the Shareholders shall be responsible for such Taxes and shall pay such Taxes in the manner provided for in Section 5.11(a) hereof. To the extent the Section 481 Adjustment will result in an increase in PMG’s income for any taxable years ending after the Closing Date (such aggregate increase in income referred to as the “Post-Closing Section 481 Adjustment”), ATS shall be responsible for any Taxes related to such increase in income and the Estimated Closing Purchase Price shall be adjusted downwards by an amount equal to (A) thirty-nine percent (39%) multiplied by (B) the amount of the Post-Closing Section 481 Adjustment multiplied by (C) a present value factor (based on a 6.82% annual discount rate factored over a three-year period) equal to 0.877657. If the Shareholders and ATS cannot agree on the determination of the Section 481 Adjustment or the Post-Closing Section 481 Adjustment, such disagreement shall be resolved by the Auditor in a manner consistent with that set forth in Section 2.4 hereof.

(d) Closing Balance Sheet and Closing Net Working Capital. The Shareholders will deliver a proposed Closing Balance Sheet, including a calculation of the Proposed Closing Net Working Capital, prepared in accordance with GAAP and otherwise in a manner consistent with Section 2.3(b) above, together with all supporting documentation (the “Proposed Closing Balance Sheet”), to ATS within sixty (60) days after the Closing Date. If, within thirty (30) days following delivery of the Proposed Closing Balance Sheet, ATS has not given the Shareholders notice of its objection to the Proposed Closing Balance Sheet (which notice must contain a statement in reasonable detail of the basis of any such objection), then such Proposed Closing Balance Sheet shall constitute the “Closing Balance Sheet,” and the Proposed Closing Net Working Capital as shown thereon shall constitute the “Closing Net Working Capital.” If ATS gives notice of an objection, the parties shall use their respective good faith efforts to resolve any dispute by negotiation. If such dispute cannot be settled by negotiation within thirty (30) days after receipt by ATS of the Shareholders’ notice, the dispute shall be resolved in accordance with the financial issue resolution process set forth in Section 2.4.

(e) Final Adjustments to Closing Consideration.

(i) If the Estimated Net Working Capital was within the Base Net Working Capital Range (such that no adjustment to the Estimated Closing Purchase Price was effected pursuant to Section 2.3(c)), then

(A) if the Closing Net Working Capital is greater than the upper end of the Base Net Working Capital Range, the Closing Consideration will be adjusted upwards on a dollar-for-dollar basis by the amount that the Closing Net Working Capital exceeds the upper end of the Base Net Working Capital Range. The amount of such upward adjustment shall be paid to the Shareholders, pro rata in accordance with the Shareholders’ Proportionate Interests, by wire transfer of immediately available funds to the accounts designated by the Shareholders, within five (5) Business Days after the finalization of the Closing Balance Sheet pursuant to Sections 2.3(d) and/or 2.4; and

(B) if the Closing Net Working Capital is less than the lower end of the Base Net Working Capital Range, the Closing Consideration will be adjusted downwards on a dollar-for-dollar basis by the amount that the lower end of the Base Net Working Capital Range exceeds the Closing Net Working Capital. The amount of such adjustment shall be paid to ATS by the Shareholders pro rata in accordance with the Shareholders’ Proportionate Interests within five (5) Business Days after the finalization of the Closing Balance Sheet pursuant to Sections 2.3(d) and/or 2.4. In the event that either Shareholder for any reason fails to make the payments contemplated in the previous sentence, then ATS may bring an indemnification claim under Article 9, and such claim shall not be subject to the limitations set forth in Section 9.2(f)(i) and the Shareholders shall be jointly and severally liable for that payment.

(ii) If the Estimated Net Working Capital was greater than the upper end of the Base Net Working Capital Range (such that an adjustment to the Estimated Closing Purchase Price was effected pursuant to Section 2.3(c)(i)(B)), then

(A) if the Closing Net Working Capital is greater than the Estimated Net Working Capital, the Closing Consideration will be adjusted upwards on a dollar-for-dollar basis by the amount that the Closing Net Working Capital exceeds the Estimated Net Working Capital. The amount of such upward adjustment shall be paid to the Shareholders, pro rata in accordance with the Shareholders’ Proportionate Interests, by wire transfer of immediately available funds to the accounts designated by the Shareholders, within five (5) Business Days after the finalization of the Closing Balance Sheet pursuant to Sections 2.3(d) and/or 2.4; and

(B) if the Closing Net Working Capital is less than Estimated Net Working Capital, the Closing Consideration will be adjusted downwards on a dollar-for-dollar basis (1) by the amount that the Estimated Net Working Capital exceeds the Closing Net Working Capital, if the Closing Net Working Capital is greater than the upper end of the Base Net Working Capital Range, (2) by the amount that the Estimated Net Working Capital exceeds the upper end of the Base Net Working Capital Range, if the Closing Net Working Capital is within the Base Net Working Capital Range, and (3) by the amount that the Estimated Net Working Capital exceeds the upper end of the Base Net Working Capital Range, plus the amount that the lower end of the Base Net Working Capital Range exceeds the Closing Net Working Capital, if the Closing Net Working Capital is less than the lower end of the Base Net Working Capital Range. The amount of such adjustment shall be paid to ATS by the Shareholders pro rata in accordance with the Shareholders’ Proportionate Interests within five (5) Business Days after the finalization of the Closing Balance Sheet pursuant to Sections 2.3(d) and/or 2.4. In the event that either Shareholder, for any reason, fails to make the payments contemplated in the previous sentence, then ATS may bring an indemnification claim under Article 9, and such claim shall not be subject to the limitations set forth in Section 9.2(f)(i) and the Shareholders shall be jointly and severally liable for that payment.

(iii) If the Estimated Net Working Capital was less than the lower end of the Base Net Working Capital Range (such that an adjustment to the Estimated Closing Purchase Price was effected pursuant to Section 2.3(c)(i)(A)), then

(A) if the Closing Net Working Capital is less than the Estimated Net Working Capital, the Closing Consideration will be adjusted downwards on a dollar-for-dollar basis by the amount that the Estimated Net Working Capital exceeds the Closing Net Working Capital. The amount of such adjustment shall be paid to ATS by the Shareholders pro rata in accordance with the Shareholders’ Proportionate Interests within five (5) Business Days after the finalization of the Closing Balance Sheet pursuant to Sections 2.3(d) and/or 2.4. In the event that either Shareholder, for any reason, fails to make the payments contemplated in the previous sentence, then ATS may bring an indemnification claim under Article 9, and such claim shall not be subject to the limitations set forth in Section 9.2(f)(i) and the Shareholders shall be jointly and severally liable for that payment; and

(B) if the Closing Net Working Capital is greater than the Estimated Net Working Capital, the Closing Consideration will be adjusted upwards on a dollar-for-dollar basis (1) by the amount that the Closing Net Working Capital exceeds the Estimated Net Working Capital, if the Closing Net Working Capital is less than the lower end of the Base Net Working Capital Range, (2) by the amount that the lower end of the Base Net Working Capital Range exceeds the Estimated Net Working Capital, if the Closing Net Working Capital is within the Base Net Working Capital Range, and (3) by the amount that the lower end of the Base Net Working Capital Range exceeds the Estimated Net Working Capital, plus the amount that the Closing Net Working Capital exceeds the upper end of the Base Net Working Capital Range, if the Closing Net Working Capital is greater than the upper end of the Base Net Working Capital Range. The amount of such upward adjustment shall be paid to the Shareholders, pro rata in accordance with the Shareholders’ Proportionate Interests, by wire transfer of immediately available funds to the accounts designated by the Shareholders, within five (5) Business Days after the finalization of the Closing Balance Sheet pursuant to Sections 2.3(d) and/or 2.4.

If such accounting firm cannot be identified within ten (10) business days after the identification of the need for dispute resolution, the dispute shall be resolved in accordance with Section 11.11.

5.9 No Solicitation of Competitive Transactions.

From the Effective Date until the Closing or, if earlier, the termination of this Agreement in accordance with its terms, PMG and each of the Shareholders agree that they will not, directly or indirectly, or directly or indirectly through any officer, director, employee, investment banker, attorney, advisor, representative or agent (each, a “Representative”), as applicable for any or all of them: (a) solicit, initiate or knowingly encourage the submission of any inquiry, proposal or offer (whether in writing or otherwise) that constitutes, or could lead to, a proposal or offer for a merger, consolidation, business combination, recapitalization, sale of substantially all PMG’s assets, or sale of a substantial percentage of shares of capital stock (including, without limitation, by way of a public offering or private placement) involving PMG other than the Contemplated Transactions (any of the foregoing inquiries or proposals being referred to herein as an “Acquisition Proposal”); (b) engage in negotiations or discussions concerning, or provide any non-public information to any Person relating to, any Acquisition Proposal; or (c) agree to, approve or recommend any Acquisition Proposal. PMG and each Shareholder agree to notify ATS immediately (and not later than twenty-

four (24) hours) after receipt of any Acquisition Proposal or any request for non-public information in connection with an Acquisition Proposal or for access to the properties, books or records of PMG by any Person that informs PMG that it is considering making or has made an Acquisition Proposal. Such notice shall be made orally (and shall be confirmed in writing) and, subject to existing confidentiality, nondisclosure or other similar agreements, shall indicate the material terms and conditions of such proposal, inquiry or contract. If PMG learns of any such action taken by a Representative, PMG will immediately advise ATS and provide the information specified herein, subject to existing confidentiality, nondisclosure or other similar agreements.

5.10 Personnel and PMG Pension Plans.

(d) Each employee of PMG shall receive and, as a condition of continued employment by PMG or employment by ATS after the Closing, as the case may be, shall be required to sign and return, a confirmation accepting continued employment or employment and ATS’ standard employee agreements, all in the form attached hereto and incorporated herein as Exhibit H (hereinafter collectively, the “Standard Employee Documents”). Such employees shall receive after Closing compensation and benefits that are, in the aggregate, comparable to the compensation and benefits received before Closing or to that received by similarly situated ATS employees.

(e) From and after the Closing Date, any former PMG employee who signs the Standard Employee Documents and chooses to remain an employee of PMG or become an employee of ATS, as the case may be, shall be given (to the extent he or she elects to participate and it is permitted by Law), credit for past service with PMG for purposes of participation and vesting under an ATS Pension Plan (including the ATS 401(k) plan) or Welfare Plan and (other than for defined benefit pension plans) benefit accrual purposes under Welfare Plan offered by ATS to such employee, including, without limitation, any vacation/paid time off policy.

Of the total amount, $110,000 shall be paid at a future time in accordance with such employee’s employment agreement, with the remainder of the amount to be either (i) released to such former PMG employee, upon the mutual agreement of ATS and the Shareholders, upon the completion of contingencies as specified in such employee’s employment agreement, or (ii) in the event some or all of the payout contingencies in (i) are not satisfied, such amounts shall be paid to the Shareholders.

5.11 Certain Tax Matters.

(a) Tax Periods Ending on or Before the Closing Date. The Shareholders shall prepare, or cause to be prepared on a timely basis (at their sole cost and expense) and on a basis reasonably consistent with past practice (unless the Shareholders are advised otherwise by their independent, outside tax advisors), all Tax Returns with respect to PMG for taxable periods ending on or prior to the Closing Date and required to be filed thereafter (the “Prior Period Returns”). ATS shall file, or cause to be filed, on a timely basis, all such Prior Period Returns, and within five (5) Business Days of such filing, ATS shall send copies of the filed Prior Period Returns to the Shareholders. The Shareholders shall provide a draft copy of such Prior Period Returns to ATS for its review at least ten Business Days prior to the due date thereof. ATS shall provide its comments to the Shareholders within five (5) Business Days following receipt of such draft from the Shareholders, and the Shareholders shall make all changes requested by ATS in good faith (unless the Shareholders are advised in writing by their independent, outside tax advisors that such changes (x) are contrary to applicable Law, or (y) will, or are likely to, have a material adverse effect on the Shareholders or any of their Affiliates). In the event that the Shareholders do not agree to a requested change by ATS, and ATS believes such change is required by Law, the dispute shall be resolved by the Auditor in a manner consistent with that set forth in Section 2.4 hereof, and such Tax Return shall be filed in the manner determined by the Auditor. Except as provided in Sections 5.11(d) and 5.16(b), and only to the extent such Taxes have not been accrued or otherwise reserved for on the Closing Balance Sheet and included in the calculation of Closing Net Working Capital, the Shareholders shall pay, or cause to be paid, all Taxes with respect to PMG shown to be due on such Prior Period Returns by the due date of such Taxes. In the event that the Shareholders for any reason fail to make the payment contemplated in the previous sentence, then ATS may bring an indemnification claim under Article 9 and the Shareholders shall be jointly and severally liable for that payment.

(b) Tax Periods Beginning Before and Ending After the Closing Date.

(i) ATS shall prepare, or cause to be prepared, and file, or cause to be filed, on a basis reasonably consistent with past practice, any Tax Returns of PMG for Tax periods that begin before the Closing Date and end after the Closing Date (collectively, the “Straddle Periods” and each a “Straddle Period”). ATS shall permit the Shareholders to review and comment on each such Tax Return described in the preceding sentence prior to filing, and ATS shall make all changes reasonably requested by the Shareholders in good faith (unless ATS is advised in writing by its independent outside accountants or attorneys that such changes (i) are contrary to applicable Law, or (ii) will, or are likely to, have a material adverse effect on ATS or any of its Affiliates). Within fifteen (15) days after the due date for Taxes of PMG with respect to any Straddle Period, the Shareholders shall, to the extent such Taxes have not been accrued or otherwise reserved for on the Closing Balance Sheet and included in the calculation of Closing Net Working Capital, pay to ATS the amount of such Taxes that relates to the portion of such Straddle Period ending on the Closing Date (the “Pre-Closing Tax Period”). In the event that the Shareholders for any reason fail to make the payment contemplated in the previous sentence, then ATS may bring an indemnification claim under Article 9 and the Shareholders shall be jointly and severally liable for that payment.

(ii) For purposes of this Agreement:

(1) In the case of any gross receipts, income, or similar Taxes that are payable with respect to a Straddle Period, the portion of such Taxes allocable to (A) the Pre-Closing Tax Period and (B) the portion of the Straddle Period beginning on the day next succeeding the Closing Date (the “Post-Closing Tax Period”) shall be determined on the basis of a deemed closing at the end of the Closing Date of the books and records of PMG.

(2) In the case of any Taxes (other than gross receipts, income, or similar Taxes) that are payable with respect to a Straddle Period, the portion of such Taxes allocable to the Pre-Closing Tax Period shall be equal to the product of all such Taxes multiplied by a fraction the numerator of which is the number of days in the Pre-Closing Tax Period and the denominator of which is the number of days in the entire Straddle Period; provided, however, that appropriate adjustments shall be made to reflect specific events that can be identified and specifically allocated as occurring on or prior to the Closing Date (in which case the Shareholders shall be responsible for any Taxes related thereto) or occurring after the Closing Date (in which case, ATS shall be responsible for any Taxes related thereto).

(iii) ATS shall be responsible for (A) any and all Taxes with respect to the Pre-Closing Tax Period of any applicable Straddle Period to (but only to) the extent such Taxes have been accrued or otherwise reserved for on the Closing Balance Sheet and included in the calculation of Closing Net Working Capital and (B) any Taxes with respect to the Post-Closing Tax Period of the Straddle Period.

(i) ATS and the Shareholders shall cooperate fully, as and to the extent reasonably requested by any party, in connection with the filing of Tax Returns pursuant to this Section and any audit, litigation, or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information reasonably relevant to any such audit, litigation, or other proceeding and making their respective employees, outside consultants and advisors available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. ATS and the Shareholders agree (A) to retain all books and records with respect to Tax matters pertinent to PMG relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by ATS or the Shareholders, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (B) to give the other reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other so requests, ATS or the Shareholders, as the case may be, shall allow the other to take possession of such books and records.

(ii) ATS and the Shareholders further agree, upon request, to use commercially reasonable efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to the Contemplated Transactions).

(iii) ATS and the Shareholders further agree, upon request, to provide the other party with all information that either party may be required to report pursuant to Section 6043 of the Code and all Treasury Department Regulations promulgated thereunder.

(iv) Shareholders further agree, upon request, to provide ATS with all information that ATS may reasonably require to satisfy the requirements of FASB Interpretation 48.

(d) Certain Taxes. All transfer, documentary, sales, use, stamp, registration and other such Taxes and fees (including any penalties and interest) incurred in connection with the Contemplated Transactions (including any transfer or similar tax imposed by any governmental authority) shall be shared equally between ATS on the one hand and the Shareholders on the other, and each shall be responsible for one-half of such Taxes. The party required by Law to do so will file all necessary Tax Returns and other documentation with respect to all such transfer, documentary, sales, use, stamp, registration and other Taxes and fees, and, if required by applicable Law, the other parties will join in the execution of any such Tax Returns and other documentation.

(e) Indemnification and Tax Contests. ATS’ and the Shareholders’ indemnification obligations with respect to the covenants in this Section 5.11, together with the procedures to be observed in connection with any Tax Contest, shall be governed by Article 9.

(f) No Retroactive Elections. ATS shall make no elections, consents, or agreements as to Taxes with respect to PMG following the Closing Date that will have any retroactive effect on PMG and/or the Shareholders, except for the Section 338(h)(10) Election contemplated by Section 5.16 hereof.

5.12 Public Announcements.

Subject to any applicable disclosure obligations pursuant to applicable Law, no one of ATS, PMG, their Affiliates, or the Shareholders will issue any press release or make any public statement with respect to this Agreement or the Contemplated Transactions, without the prior consent of ATS, on one hand, and the Shareholders, on the other hand, which consent shall not be unreasonably withheld or delayed.

5.13 Communications with Customers and Suppliers.

The Shareholders and ATS will mutually agree upon all communications with suppliers and customers of PMG relating to this Agreement and the Contemplated Transactions as soon as possible after the Effective Date and in ample time prior to the Closing Date in order to minimize the effect of the Contemplated Transactions on PMG’s business operations and its relationships with customers, vendors and other third party relationships.

5.14 Non-Competition and Non-Solicitation of Employees.

(a) For a period of four (4) years after the Closing Date (the “Non-Competition Period”), no Shareholder shall, directly or indirectly, as principal, agent, employee, employer, consultant, independent contractor, stockholder, partner or in any other individual capacity whatsoever (except as permitted herein), engage in any Competitive Business Activities or permit (to the extent he or she has control over an Affiliate) any of his or her Affiliates to engage in any Competitive Business Activities, without the written consent of ATS. For purposes of this Agreement, “Competitive Business Activity” means any business activities that are competitive with the activities of the Acquired Business. The foregoing shall not prevent any Shareholder from owning for investment purposes up to 5% of the outstanding securities of a publicly traded company engaged in a Competitive Business Activity (provided, that, in no event shall the Shareholders in the aggregate own more than 5% of the outstanding securities of a publicly traded company engaged in a Competitive Business Activity).

(b) For a period of five (5) years after the Closing Date, no Shareholder shall (for his or her own benefit or for the benefit of any Person other than ATS or PMG) solicit, or assist any Person other than ATS or PMG to solicit, any officer, director, executive or employee of PMG or ATS or any of their respective Affiliates to leave his or her employment; provided, however, that this provision shall not prohibit any Shareholder from soliciting any such Person through a general advertisement or other means not targeted at officers, directors, executives or employees of PMG and hiring any Person who responds to any such general advertisement or other means.

(c) During the Non-Competition Period, the Shareholders shall not, either individually for himself or herself, or for the benefit of any other Person, either as employee, consultant, investor or in any other capacity whatsoever, contact any Customer or Prospective Customer for the purpose of selling any products or services that constitute a Competitive Business Activity. For purposes of this Agreement, “Customer” means any Person that has purchased products or services from PMG at any time within two (2) years prior to the Closing Date, and “Prospective Customer” means any Person that PMG was actively soliciting as of the Closing Date.

(d) Each Shareholder hereby acknowledges that (i) the markets served by ATS are not limited geographically, (ii) the length of the restrictions in, and the scope of, this Section 5.14 were negotiated in the context of the Contemplated Transactions, (iii) he or she will receive a substantial portion of the consideration payable to the Shareholders hereunder, and (iv) the covenants in this Section 5.14 are manifestly reasonable on their face and have been designed to be reasonable and no greater than is required for the protection of ATS.

(e) Each of the Shareholders agrees that ATS’ remedies at Law for any breach or threat of breach by him or her of any of the provisions of this Section 5.14 will be inadequate and that ATS shall be entitled to an injunction or injunctions to prevent breaches of the provisions of this Section 5.14 and to enforce specifically the terms and provisions thereof, in addition to any other remedy to which ATS may be entitled at law or equity.

(f) Each of ATS and the Shareholders agrees that the Purchase Consideration shall be allocated for Tax purposes to the agreements set forth in this Section 5.14 in accordance with Schedule 5.14(f) of the Disclosure Schedules (such Schedule to be agreed upon by the parties as soon as reasonably practicable after the Effective Date).

(g) Should any provision of this Section 5.14 be determined to be unenforceable or prohibited by applicable law, such provision shall be ineffective to the extent, and only to the extent, of such unenforceability or prohibition without invalidating the balance of such provision or any other provision of this Section 5.14 above.

5.15 Notification of Certain Matters.

The Shareholders and PMG shall give prompt (but in any case within two (2) Business Days) notice to ATS, and ATS shall give prompt (but in any case within two (2) Business Days) notice to the Shareholders and PMG (a) of the occurrence or non-occurrence of any event the occurrence or non-occurrence of which would cause any representation or warranty contained in this Agreement to be untrue or inaccurate in any material respect at or prior to the Closing Date, (b) of any material failure of PMG, the Shareholders, or ATS, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder, and (c) if they become aware of facts or circumstances that make the conditions under Article 6 hereof impossible or unlikely to occur on or before August 31, 2007; provided, however, that the delivery of any notice pursuant to this Section 5.15 shall not limit or otherwise affect the remedies available hereunder to the party receiving such notice; provided, further, that any delay in providing notice under this Section 5.15 shall not be deemed to constitute a breach of such party’s obligations hereunder unless any party would be materially prejudiced by such delay.

5.16 338(h)(10) Election.

(a) At ATS’ option, the Shareholders will join with ATS in making an election under Section 338(h)(10) of the Code, and any comparable elections under state, local or foreign income Tax law, with respect to PMG (collectively, the “Section 338(h)(10) Election”), and the Shareholders shall cooperate in the completion and timely filing of such elections in accordance with the provisions of Treasury Regulation §1.338(h)(10)-1 (or any comparable provisions of state or local income Tax law) or any successor provision. ATS shall inform the Shareholders, on or before December 1, 2007, whether or not it elects to proceed with the Section 338(h)(10) Election. Not less than three (3) Business Days prior to making such election, ATS shall deliver to the Shareholders a completed copy of IRS Form 8023, which the Shareholders shall execute and deliver to ATS within three (3) Business Days. On or prior to December 1, 2007, ATS shall, if it elects to file the Section 338(h)(10) Election, deliver to the Shareholders completed copies of IRS Form 8883 and required schedules thereto, as well as any applicable state or local forms (together with IRS Form 8023, the “Section 338 Forms”). ATS and the Shareholders shall act in good faith to (i) determine and agree upon the amount of the aggregate deemed sales price (“ADSP”) (within the meaning of Treas. Reg. §1.338(h)(10) 1(d)(3) and

§1.338-4 and (ii) agree upon the proper allocations (the “Allocations”) of the ADSP among the assets of PMG in accordance with Treas. Reg. §1.338(h)(10)-1(d) (3), §1.338-6, and §1.338-7. The allocation of the Purchase Consideration among the assets of PMG shall be made in accordance with their relative fair market values, in a manner consistent with Code Sections 338 and 1060 and Treasury Regulations thereunder and any comparable provisions of state or local income Tax law, and such allocation shall be provided by ATS to the Shareholders on or before the date on which IRS Form 8883, which shall reflect the agreement of ATS and the Shareholders required in the preceding sentence, is delivered to them. For this purpose, the parties hereby agree that the fair market value of PMG’s inventory, property plant and equipment, and accounts receivable shall be equal to their net book values as provided in PMG’s Closing Balance Sheet. If the Section 338 Forms are correct and complete in the reasonable determination of the Shareholders, ATS and the Shareholders will, subject to the requirements of any applicable Tax law or election, file all Tax Returns and reports consistent with the allocation provided in the Allocation Schedule. ATS shall be responsible for the preparation and filing of the Section 338(h)(10) Election and the costs incurred therein.

(b) Within thirty (30) days after the delivery of the Section 338 Forms to the Shareholders, ATS shall indemnify and reimburse the Shareholders, by wire transfer of immediately available funds to an account or accounts designated by the Shareholders, on a Grossed-Up Basis, for any Taxes incurred by the Shareholders by reason of the Section 338(h)(10) Election that would not have been incurred but for the Section 338(h)(10) Election (the “Grossed-Up Section 338(h)(10) Reimbursement”). For the avoidance of doubt, (a) the Grossed-Up Section 338(h)(10) Reimbursement payable to the Shareholders includes, without limitation, (i) any additional state and/or local Taxes imposed on the Shareholders attributable to the Section 338(h)(10) Election and (ii) any increase in the Shareholders’ Tax liability due to the characterization of a portion of the gain on the deemed asset sale as ordinary income (except for any increased Tax liability attributable to the acceleration of adjustments under Section 481 of the Code resulting from the Section 338(h)(10) Election), and (b) there shall be no implied “reverse” indemnification and reimbursement by the Shareholders to ATS under this Section 5.16(b) in the event that the Section 338(h)(10) Election results in a tax savings to the Shareholders. Furthermore, any Taxes imposed under Section 1374 of the Code and any additional state and/or local Taxes imposed on PMG attributable to the Section 338(h)(10) Election (including, without limitation, any entity-level state Taxes such as the District of Columbia Corporate Franchise Tax) shall be the responsibility of ATS and PMG, and the Shareholders shall have no liability for such Taxes, whether by indemnity or otherwise.

(c) In determining the amount of Purchaser’s Grossed-Up Section 338(h)(10) Reimbursement, (i) any income, deduction, gain, loss, credit or other Tax items resulting to the Shareholders from any source other than PMG, the Contemplated Transactions or the Section 338(h)(10) Election, and (ii) any personal Tax attributes of the Shareholders (including, but not limited to, any net operating loss carryovers, capital loss carryovers, Tax credit carryovers, or passive loss carryovers) originating from any source other than PMG, shall be ignored.

(d) The parties agree that any payment under this Section 5.16 shall be treated as an adjustment to the Purchase Consideration and added to any other adjustments specified in this Agreement. At Closing, an estimate of the Grossed-Up Section 338(h)(10) Reimbursement, based upon the Estimated Closing Balance Sheet, shall be calculated by the Shareholders and submitted to ATS for its review, along with supporting work papers. Within twenty (20) days after delivery of the Section 338 Forms to the Shareholders, a final Grossed-Up Section 338(h)(10) Reimbursement shall be calculated by the Shareholders and submitted to ATS for its approval, along with supporting work papers. Such approval shall not be unreasonably withheld, delayed or conditioned. If the parties are unable to agree as to the Grossed-Up Section 338(h)(10) Reimbursement, ATS shall promptly pay any undisputed amount, and any disputed amount shall be resolved by the Auditor in a manner consistent with that set forth in Section 2.4 hereof.

5.17 Notification of Certain Matters; Supplemental Disclosure.

(a) PMG shall promptly notify ATS if the employment by PMG of any member of its senior management team or any Key Employee terminates for any reason or if any such individual provides written notice of his or her intention to terminate his or her employment with PMG.

(b) The Disclosure Schedules are attached to this Agreement as of the execution of this Agreement. On or prior to two (2) Business Days before the Closing, PMG will provide to ATS updated Disclosure Schedules, revised as necessary from the version delivered as of the execution of this Agreement, excluding any Disclosure Schedules that are made with respect to specified dates, which are not required to be updated. For purposes of Section 9.2(b) hereof, no update or revision to any part of the Disclosure Schedules pursuant to this Section 5.17 shall be deemed to cure any breach of any representation or warranty resulting from such condition.

5.18 Indemnification.

ATS shall cause all rights to indemnification existing in favor of those Persons who are directors and officers of PMG as of the Effective Date for their acts and omissions occurring prior to the Closing to continue to exist, to the fullest extent available under Virginia Law, for a period of six (6) years from the Closing Date. Nothing in this Agreement shall restrict or prohibit PMG from procuring a “tail” for its directors’ and officers’ insurance policy.

5.19 Termination of Lines of Credit.

The Shareholders shall cause PMG to terminate prior to Closing any agreement or arrangement pursuant to which PMG has agreed to provide credit or make any loans to any Person (or guaranty the Indebtedness of any Person), except trade credit extended in the ordinary course of business.

5.20 Change of Control Payments.

On or prior to the Closing Date, the Shareholders shall pay any and all payments required to be made by PMG as a result of the consummation of the Contemplated Transactions as well as the Employee Closing Bonuses. To the extent that any such amount has not been paid by the Shareholders prior to Closing, such amount, plus the employer portion of any applicable payroll taxes, shall be paid by ATS at Closing as a deduction against the Closing Consideration, (by wire transfer to PMG, in immediately available funds, to an account designated by PMG, and a corresponding payment by PMG to the subject employees, net of required withholdings). If paid by ATS at Closing as a deduction against the Closing Consideration, such amount shall not be reflected as a liability on the Closing Balance Sheet, and shall not adversely affect Closing Net Working Capital.

5.21 Accounts Receivable.

With respect to any receivables that ultimately are not collected and are counted against the limitation set forth in Section 9.2(g) hereof or are satisfied by an offset against the Promissory Notes in accordance with Section 3.5(d) and Article 9 hereof, ATS shall cause PMG to continue to use collection activity efforts consistent with PMG’s past practices, and shall promptly remit to the Shareholders, or shall cause PMG promptly to remit to the Shareholders, any amount of such uncollected receivables that are received after the Closing by PMG or ATS.

5.22 8(a) Contract.

(a) On March 11, 2004, PMG was awarded a contract with the U.S. Coast Guard (Contract No. HSCG-32-04-D-R00005) pursuant to Section 8(a) of the Small Business Act (the “8(a) Contract”).

(b) Immediately after the Effective Date, PMG shall provide the Small Business Administration (the “SBA”) and the contracting officer for the 8(a) Contract written notification of the Contemplated Transactions in accordance with all applicable Laws and the requirements of the 8(a) Contract. Such written notification shall be in the form and substance reasonably acceptable to ATS, and PMG shall provide ATS a copy of the notification provided to the SBA and the contracting officer pursuant to this Section 5.22(b).

(c) Unless the SBA Administrator grants a waiver, the 8(a) Contract must be terminated after the Closing of the Contemplated Transactions because PMG no longer will be at least 51% owned by the disadvantaged individual upon whom PMG’s eligibility for the 8(a) business development program was based.

(d) PMG shall use commercially reasonable efforts to obtain from the head of the procuring agency for the 8(a) Contract (or an official with delegated authority for such agency head), as soon as practicable, a written certification that the termination of such 8(a) Contract would severely impair attainment of such agency’s program objective or missions (an “Agency Impairment Certification”). ATS shall use commercially reasonable efforts to assist PMG’s efforts in this regard.

(e) Prior to the Closing, PMG shall submit a written request to the SBA Administrator in accordance with all applicable Laws and the requirements of the 8(a) Contract requesting the SBA Administrator to waive the requirement that the 8(a) Contract be terminated for the convenience of the government because, after the Closing of the Contemplated Transactions, PMG no longer will be at least 51% owned by the disadvantaged individual upon whom PMG’s eligibility for the 8(a) business development program was based (the “8(a) Contract Waiver Request”). ATS shall use commercially reasonable efforts to assist PMG’s efforts in this regard. The 8(a) Contract Waiver Request shall be in the form and substance reasonably acceptable to ATS and shall either be accompanied by the Agency Impairment Certification for the 8(a) Contract (if obtained pursuant to Section 5.22(d) hereof prior to such submission), or, if obtained after such submission, such Agency Impairment Certification shall be submitted promptly as a subsequent addendum to the 8(a) Contract Waiver Request to the SBA Administrator.

After the expiration of such period, such representations and warranties shall expire and be of no further force and effect except to the extent that a claim or claims shall have been asserted and notice thereof provided by ATS or the Shareholders, as the case may be, with respect thereto on or before the expiration of such period, provided however, that the following representations and warranties (collectively, the “Surviving Representations”) shall survive the Survival Date until the date specified below:

(ii) The obligations of ATS under paragraph (i) of this Section 9.2(a) shall extend to (A) all Taxes with respect to taxable periods beginning after the Closing Date (including any Taxes with respect to transactions properly treated as occurring on the day after the Closing Date pursuant to Treasury Regulations Section 1.1502-76(b)(1)(ii)(B) or any similar provision of state, local or foreign law), (B) all Taxes (other than income Taxes) with respect to Straddle Periods to the extent that such Taxes are allocable to the period after Closing pursuant to Section 5.11(c) and (C) all additional Taxes or other costs associated with the Section 338(h)(10) Election as described in Section 5.16.

(ii) The obligations of the Shareholders under paragraph (i) of this Section 9.2(b) shall extend to (A) all Taxes with respect to taxable periods ending on or prior to the Closing Date and (B) all Taxes with respect to Straddle Periods to the extent that such Taxes are allocable to the period prior to Closing pursuant to Section 5.11(b); provided, however, that such obligations of the Shareholders shall not extend to Taxes and related reimbursement obligations for which ATS is responsible pursuant to Section 5.16(b) hereof. Such obligations of the Shareholders shall be without regard to whether there was any breach of any representation or warranty under Article 3 with respect to such Tax or any disclosures that may have been made with respect to Article 3 or otherwise. The indemnification obligations under this paragraph (ii) shall apply even if the additional Tax liability results from the filing of a return or amended return with respect to a pre-Closing Date transaction or period (or portion of a period) by ATS as permitted by this Agreement. ATS shall not cause or permit PMG to file an amended Tax Return with respect to any taxable period ending on or prior to the Closing Date or any Straddle Period unless the Shareholders consent in their sole discretion or ATS obtains a legal opinion from counsel reasonably acceptable to the Shareholders that such amendment is legally required to be filed (provided, further, that such legal opinion may not assume any facts that are disputed in good faith by the Shareholders). In the event of any conflict between the provisions of this Section 9.2(b)(ii) and any other provision of this Agreement, the provisions of this Section shall control.

(i) If any Third-Party Claims shall be commenced, or any claim or demand shall be asserted (other than audits or contests with Taxing Authorities relating to Taxes), in respect of which the Indemnified Party proposes to demand indemnification by Indemnifying Party under Sections 9.2(a) or 9.2(b), the Indemnified Party shall notify the Indemnifying Party in writing of such demand, setting forth in reasonable detail the basis for the claim and a reasonable estimate of the amount of such claim, if estimable, and the Indemnifying Party shall have the right to assume the entire control of the defense, compromise or settlement thereof (including the selection of counsel), subject to the right of the Indemnified Party to participate (with counsel of its choice, but the fees and expenses of such additional counsel shall be at the expense of the Indemnified Party). The Indemnifying Party will not compromise or settle any such action, suit, proceeding, claim or demand (other than, after consultation with Indemnified Party, an action, suit, proceeding, claim or demand to be settled by the payment of money damages and/or the granting of releases, provided that no such settlement or release shall acknowledge the Indemnified Party’s liability for future acts or obligate ATS with respect to activities of PMG) without the prior written consent of the Indemnified Party, which consent shall not be unreasonably withheld.

(ii)(A) Except as otherwise provided in paragraph (B), ATS shall have the sole right to control and make all decisions regarding interests in any Tax audit or administrative or court proceeding relating to Taxes, including selection of counsel and selection of a forum for such contest, provided, however, that in the event such audit or proceeding relates to Taxes for which the Shareholders are responsible and have agreed to indemnify ATS, (i) ATS, PMG, and the Shareholders shall cooperate in the conduct of any audit or proceeding relating to such period, (ii) the Shareholders shall have the right (but not the obligation) to participate in such audit or proceeding at the Shareholders’ expense, and (iii) ATS shall not enter into any agreement with the relevant taxing authority pertaining to such Taxes without the written consent of the Shareholders, which consent shall not unreasonably be withheld.

(B) With respect to any Tax audit or administrative or court proceeding relating to (i) any federal income Tax Return of PMG for any taxable period ending on or before the Closing Date or (ii) any state income Tax Return of PMG for any state in which PMG is treated as an S corporation for any taxable period ending on or before the Closing Date, Shareholders shall have the sole right to control and make all decisions regarding interests in such audit or proceeding, including selection of counsel and selection of a forum for such contest, provided, however, that (i) ATS, PMG, and the Shareholders shall cooperate in the conduct of any audit or proceeding relating to such period, (ii) ATS and PMG shall have the right (but not the obligation) to participate in such audit or proceeding at their expense, and (iii) the Shareholders shall not enter into any agreement with the relevant taxing authority pertaining to such Taxes (if such agreement will have a material adverse effect on ATS or PMG) without the written consent of ATS, which consent shall not unreasonably be withheld.

(iii) The parties will keep each other informed as to matters related to any audit or judicial or administrative proceedings involving Taxes for which indemnification may be sought hereunder, including, without limitation, any settlement negotiations. Refunds of Tax relating to periods ending prior to the Closing Date (or to that portion of a Straddle Period that is prior to Closing under the principles of Section 5.11(b) shall be the property of the Shareholders, but only to the extent that such refunds are not attributable to (A) net operating loss or other carrybacks from periods ending after the Closing Date, (B) refund claims that are initiated by ATS (provided that ATS gives the Shareholders prior notice of such possible claim and the Shareholders decline to pursue such refund at their own expense) or (C) refunds reflected in the calculation of Closing Net Working Capital; provided, however, that ATS shall in no event have an obligation to file or cause to be filed a claim for refund with respect to any Taxes relating to any period. All other refunds of Tax are the property of ATS.

(iv) Any indemnity payment or payment of Tax by the Shareholders or their Affiliates as a result of any audit or contest shall be reduced by the correlative amount, if any, by which any Tax of ATS or its Affiliates is actually reduced for periods ending after the Closing Date as a result thereof.

(v) The Indemnified Party shall cooperate fully in all respects with the Indemnifying Party in any defense, compromise or settlement, subject to this Section 9.2(c) including, without limitation, by making available all pertinent books, records and other information and personnel under its control to the Indemnifying Party.

(vi) Notwithstanding anything to the contrary contained in this Section 9.2(c), ATS shall have the sole right to control and make all decisions regarding any Third Party Claim involving a material past, current or future PMG customer or vendor; provided, however, that in the event the Shareholders are responsible and have agreed to indemnify ATS for such Third Party Claim, (A) ATS, PMG, and the Shareholders shall cooperate in the defense, compromise or settlement thereof, (B) the Shareholders shall have the right (but not the obligation) to participate in the defense, compromise or settlement thereof at the Shareholders’ expense, and, (C) any compromise or settlement by ATS shall not be made without the prior written consent of the Shareholders, which consent shall not be unreasonably withheld.

(d) Procedure for Direct Claims.

(i) Any Direct Claim shall be asserted by written notice given by the Indemnified Party to the Indemnifying Party (each a “Direct Claim Notice”), setting forth in reasonable detail the basis for the claim and a reasonable estimate of the amount of such claim, if estimable. The Indemnified Party shall provide the Indemnifying Party with reasonable access to information and records necessary for the Indemnifying Party to evaluate the claim. The Indemnifying Party shall have a period of twenty (20) Business Days from the date of receipt (the “Direct Claim Notice Period”) within which to respond to a Direct Claim Notice. If the Indemnifying Party does not respond in writing within the Direct Claim Notice Period, then the Indemnifying Party shall be deemed to have accepted responsibility for the claimed indemnification and shall have no further right to contest the validity of that claim. If the Indemnifying Party does respond in writing within the Direct Claim Notice Period, and rejects the claim in whole or in part, the Indemnified Party shall be free to pursue all remedies under Section 11.11. To the extent that any ATS Indemnitees prevail in a Direct Claim (or the Shareholders concede, or otherwise do not timely respond to a Direct Claim Notice made by ATS), then the Direct Claim shall be satisfied from an offset against the Promissory Notes with no further action required by the Shareholders. In the event that such a Direct Claim constitutes a “Non-Threshold Indemnification” (as hereinafter defined) and is in excess of the “Note Cap” (as hereinafter defined), the Shareholders shall be and remain jointly and severally liable for the amount of such excess.

(ii) Costs Related to Direct Claims. Notwithstanding anything in this Section 9.2 to the contrary, the Shareholders’ Indemnitees and ATS Indemnitees shall each bear their own costs, including counsel fees and expenses, incurred in connection with Direct Claims against ATS and the Shareholders, respectively, hereunder that are not based upon claims asserted by third parties.

(e) Calculation of Amount of Claims and Losses. The amount of any claims or losses subject to indemnification under Section 9.2(b) shall be calculated net of any amounts recovered by ATS or its Affiliates (including PMG after the Closing) under applicable insurance policies held by ATS or its Affiliates, and ATS agrees to make or cause to be made all reasonable claims for insurance under such policies that may be applicable to the matter giving rise to the indemnification claim hereunder. The amount of any claims or losses subject to indemnification under Section 9.2(b) shall be calculated net of any Tax benefits actually received by ATS or its Affiliates (including PMG after the Closing) resulting from the matter giving rise to the indemnification claim hereunder.

(f) Limitations on Rights of ATS Indemnitees.

(i) Notwithstanding anything to the contrary contained herein and subject to Section 9.2(f)(ii):

(A) the rights of ATS Indemnitees to indemnification by the Shareholders for breaches of representations and warranties (but not breaches of covenants) hereunder shall be subject to the limitation that ATS Indemnitees shall not be entitled to indemnification with respect to a claim or claims of breach of representation and warranty by the Shareholders unless the aggregate amount of all such claims exceeds $180,000, in which event the indemnity provided for in this Section 9.2 shall be effective with respect to the total amount of such claims that is in excess of $180,000; and

(B) the Shareholders’ liability to the ATS Indemnitees shall be limited to the Note Cap.

(ii) The limitation in Section 9.2(f)(i) shall not apply to the “Non-Threshold Indemnifications” as hereinafter defined. For purposes of this Agreement, the term “Non-Threshold Indemnifications” shall mean and refer collectively to indemnification liabilities of the Shareholders pursuant to claims based upon (A) the indemnification liabilities of the Shareholders pursuant to any of the Surviving Representations or clauses (B), (C) or (D) of Section 9.2(b)(i); or (B) claims based on fraud or criminal acts on the part of the Shareholders, PMG or their respective officers, directors, agents, representatives and trustees. The Shareholders’ aggregate maximum liability for all indemnification claims under Sections 9.2(f)(i) and 9.2(f)(ii) shall not exceed the Purchase Consideration.

(iii) Notwithstanding anything to the contrary in this Agreement, but subject to the limitations set forth in this Agreement, any indemnification obligations of the Shareholders shall first be satisfied from offsets of the Promissory Note prior to any ATS Indemnitee exercising any other remedy, offset or action to seek recovery of amounts payable to any ATS Indemnitee pursuant to Shareholders’ indemnification obligations.

(g) Limitations on Rights of Shareholder Indemnitees. The rights of Shareholder Indemnitees to indemnification by ATS for breaches of representations and warranties (but not breaches of covenants) hereunder shall be subject to the limitation that Shareholder Indemnitees shall not be entitled to indemnification with respect to a claim or claims for a breach of representation and warranty by (but not breaches of covenants) ATS unless the aggregate of damages with respect to all such claims exceeds $180,000, in which event the indemnity provided for in this Section 9.2 shall be effective with respect to the amount of such damages in excess of $180,000. The aforementioned limitation shall not apply to the indemnification liabilities of ATS with respect to claims based on fraud, intentional misrepresentation, or criminal acts on the part of ATS.

(h) Limitation on Rights Against PMG. Notwithstanding anything to the contrary, ATS and the Shareholders acknowledge and agree that, following the Closing, they shall have no right to make a claim against PMG pursuant to this Article 9.

(i) Limitations on Remedies. No party hereto shall be liable to the other for indirect, special, incidental, consequential, exemplary or punitive damages claimed by such other party resulting from such first party’s breach of its obligations, agreements, representations or warranties hereunder, provided that nothing hereunder shall preclude any recovery by an Indemnitee against an Indemnitor for third party claims.

(j) Subrogation. Except to the extent of any insurance policy which includes a waiver of subrogation, upon making an indemnity payment pursuant to this Agreement, the Indemnifying Party will, to the extent of such payment, be subrogated to all rights of the Indemnified Party against any third party in respect of the damages to which the payment related. Without limiting the generality of any other provision hereof, each such Indemnified Party and Indemnifying Party will duly execute upon request all instruments reasonably necessary to evidence and perfect the above described subrogation rights.

(k) Adjustment to Purchase Price. All indemnity payments made pursuant to this Article 9 or otherwise shall be treated for all Tax purposes as an adjustment to the Purchase Consideration.

(l) Mitigation. Each party agrees to use reasonable efforts to mitigate any loss, liability or damage which forms the basis of a claim hereunder.

9.3 Promissory Notes and Indemnification Cap.

Pursuant to Section 2, at the Closing, ATS shall deliver the Promissory Notes to secure the Shareholders’ indemnification obligations under this Article 9. Except with respect to the Non-Threshold Indemnifications, the sole recourse of the ATS Indemnitees in respect of breach of representations and warranties (but not breaches of covenants) shall be to offset such claims against the then outstanding principal amount of the Promissory Notes, plus accrued interest, at the time of such a claim is asserted (the “Note Cap”).

9.4 Effect of Investigation.

The right to indemnification or other remedies based on any representation, warranty, covenant or obligation contained in or made pursuant to this Agreement or the Transaction Documents shall not be affected by any investigation conducted with respect to the accuracy or inaccuracy of or compliance with, any such representation, warranty, covenant or obligation. The waiver of any condition to the obligation to consummate the Contemplated Transactions, where such condition is based on the accuracy of any representation or warranty, or on the performance of or compliance with any covenant or obligation, shall not affect any right to indemnification or other remedies based on such representation, warranty, covenant or obligation otherwise provided in this Agreement.

(a) at any time, by mutual written agreement of the Shareholders and ATS;

(b) at any time after September 15, 2007, by either the Shareholders or ATS upon five (5) Business Days’ prior written notice to the other party, if the Closing shall not have occurred for any reason other than a breach of this Agreement by the terminating party;

(c) by ATS, if there has been a material violation or breach by the Shareholders of any agreement, representation or warranty contained in the Agreement (as such representation or warranty is modified by the Disclosure Schedules, as such Disclosure Schedules may be updated pursuant to Section 5.17(b) hereof), and either (i) the Shareholders have not cured such violation or breach within thirty (30) days of receipt or written notice thereof or (ii) such violation or default has rendered the satisfaction of any condition to the obligations of ATS impossible and such violation or breach has not been waived by ATS;

(d) by the Shareholders, if there has been a material violation or breach by ATS of any agreement, representation or warranty contained in the Agreement, and either (i) ATS has not cured such violation or breach within thirty (30) days of receipt or written notice thereof or (ii) such violation or default has rendered the satisfaction of any condition to the obligations of the Shareholders impossible and such violation or breach has not been waived by the Shareholders; or

(e) by either ATS or the Shareholders if a court of competent jurisdiction shall have issued an order permanently restraining or prohibiting the Contemplated Transactions, such order is not the result of a breach of this Agreement by the party seeking its termination and such order shall have become final and nonappealable.

10.2 Procedure and Effect of Termination.

In the event of the termination of this Agreement and the abandonment of the Contemplated Transactions, written notice thereof shall be given by a terminating party to the other parties and this Agreement shall terminate and the Contemplated Transactions shall be abandoned without further action by the Shareholders or ATS. If this Agreement is terminated pursuant to Section 10.1:

(a) ATS shall, upon written request from the Shareholders, return all documents, work papers and other materials (and all copies thereof) obtained from the Shareholders or PMG relating to the Contemplated Transactions, whether so obtained before or after the execution hereof, to the party furnishing the same, and all confidential information received by ATS with respect to PMG shall be treated in accordance with Section 5.2 and the Confidentiality Agreement referred to in such Section;

(b) At the option of the Shareholders, all filings, applications and other submissions made pursuant to Section 5.4 shall, to the extent practicable, be withdrawn from the agency or other Person to which made;

(c) The obligations provided for in this Section 10.2, Sections 5.2(b) and 5.7, and in the Confidentiality Agreement shall survive any such termination of this Agreement; and

(d) Notwithstanding anything in this Agreement to the contrary, but subject to the limitations of liability set forth in this Agreement, the termination of this Agreement shall not relieve any party from liability for breach of this Agreement; provided, however, that if any Shareholder would otherwise have any liability as a result of this Section 10.2(d), the parties hereto agree that such liability will be deemed to be a liability of PMG and not of such Shareholder.
