All items on the Closing Date Balance Sheet shall be determined and computed in accordance with GAAP in effect as of the date hereof, applied in accordance with the reasonable past practice of the Company. The Purchaser, in conjunction with its independent accountants, shall prepare and present to the Stockholder Representative a draft of the Closing Date Balance Sheet (the “Preliminary Closing Date Balance Sheet”) promptly, but not more than sixty (60) days after the Closing Date. The Stockholder Representative and its independent accountants shall have the right to observe and participate in the preparation of the Preliminary Closing Date Balance Sheet and, during such sixty (60) day period, the Purchaser shall provide the Stockholder Representative and its independent accountants and other authorized representatives with reasonable access to the Company’s facilities, books and records and its personnel and accountants; provided, however, that (i) such observation, participation and access shall not unreasonably interfere with the business operations of the Purchaser or its Subsidiaries; (ii) the Purchaser shall not be required to provide access to any information or take any other action that would constitute a waiver of the attorney-client privilege; and (iii) the Purchaser need not supply any Person with any information which, in the reasonable judgment of the Purchaser, the Purchaser is under a legal obligation not to supply.

(d) Post-Closing Adjustment Disputes. The Stockholder Representative shall notify the Purchaser of any dispute with the Preliminary Closing Date Balance Sheet, identifying with specificity the disputed calculations, in writing promptly, but not more than thirty (30) days after its receipt by the Stockholder Representative. If the parties cannot agree on the terms of the Preliminary Closing Date Balance Sheet within thirty (30) days after the Stockholder Representative has notified the Purchaser of the dispute in writing regarding the Preliminary Closing Date Balance Sheet, the parties shall submit the dispute to a mutually acceptable independent “Big Four” accounting firm (the “Reviewing Accountants”), whose determination of the Actual Net Asset Amount and the Actual Debt shall be binding on the parties. The fees of such Reviewing Accountants shall be borne by the Purchaser if an adjustment is made in favor of the Stockholders and by the Stockholders if no adjustment or an adjustment in the Purchaser’s favor is made. The Preliminary Closing Date Balance Sheet, together with any adjustments or corrections agreed upon by the Purchaser and the Stockholder Representative and/or determined by the Reviewing Accountants, shall comprise the final Closing Date Balance Sheet.

Section 2.7 Imputed Interest. The parties hereto shall treat such portion of any payment to the Stockholders under this Agreement as imputed interest to the extent required pursuant to Section 483 or Section 1274 of the Code.

Section 2.8 Withholding. The Purchaser (and, after the Closing, at the Purchaser’s election, the Company) shall be entitled to

deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as it reasonably determines it should deduct and withhold with respect to the making of such payment under the Code and the rules and Treasury Regulations promulgated thereunder, or any provision of state, local or foreign Tax Law. To the extent that amounts are so withheld or paid over to or deposited with the relevant Governmental Authority, including any Taxing Authority, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made by the Purchaser (or the Company, as applicable). The Purchaser and the Stockholders shall cooperate and work in good faith to eliminate or minimize any such withholding.

In the event that a Stockholder is required by Law, regulation, supervisory authority or other applicable judicial or governmental order to disclose any of the Confidential Information the Stockholders shall provide the other party, as applicable, with prompt written notice, unless notice is prohibited by Law, of any such request or requirement so that the other party may seek a protective order or other appropriate remedy. If, failing the entry of a protective order (which the party required to disclose will use its commercially reasonable efforts to obtain), the party required to disclose the Confidential Information is, in the opinion of its counsel, compelled to disclose such Confidential Information, such party may disclose that portion of the Confidential Information that counsel advises that such party is compelled to disclose and will exercise commercially reasonable efforts to obtain assurance to the extent possible that confidential treatment will be accorded to that portion of the Confidential Information that is being disclosed. In any event, the party required to disclose the Confidential Information will use its commercially reasonable efforts to, and will not oppose action by the other party to, obtain an appropriate protective order or other reliable assurance that confidential treatment will be accorded the Confidential Information. The parties’ obligations under this Section 7.6 shall survive the termination of this Agreement.

Section 10.2 Indemnification Obligations.

(a) Stockholder Indemnification Obligations. Subject to the limitations set forth in this Article X, each Stockholder, severally but not jointly, in the proportion to such Stockholder’s Ownership Percentage as set forth on Exhibit A (as it may be revised pursuant to Section 3.2), shall indemnify, defend and hold harmless the Purchaser, the Company (following Closing), and any parent, subsidiary, associate, Affiliate, director, officer, stockholder or agent thereof, and their respective Representatives, successors and permitted assigns (all of the foregoing are collectively referred to as the “Purchaser Indemnified Parties”), from and against all Losses which any such party may suffer, sustain or become subject to, to the extent relating to:

(i) any inaccuracy in, or breach of, any representation or warranty made by the Company or any Stockholder under this Agreement or any Ancillary Agreement (without regard to any materiality qualifiers contained therein);

(ii) any breach or non-fulfillment of any covenant or agreement on the part of such Stockholder or the Company, under this Agreement or any Ancillary Agreement;

(iii) any fees, expenses or other payments incurred or owed by the Stockholders or the Company to any counsel, advisor, agent, broker, investment banker or other firm or Person retained or employed in connection with the transactions contemplated by this Agreement;

(iv) all Taxes of the Company and the Company’s Subsidiaries for any taxable period ending on or before the Closing Date and any Pre-Closing Tax Period (including (A) any withholding or other Tax related to the payment of the special cash distributions contemplated by Section 7.10 hereof and (B) any Tax of AmTech Capital Management Holding, Inc. relating to the withdrawal as a Member from AmTech Capital Management, LLC, as contemplated by Section 7.12 hereof, but excluding for purposes of this subsection (iv) any Taxes required to be withheld pursuant to applicable Tax Law in connection with any payments made to the holders of Company Vested Options or Company Unvested Options pursuant to Sections 2.2, 2.3 or 2.4 of this Agreement), except to the extent such Taxes are set forth in the reserve for Taxes on the Closing Date Balance Sheet (without regard to deferred Tax assets and liabilities) and taken into account in determining an adjustment to the Purchase Price pursuant to Section 2.6 hereof;

(v) all Taxes, whether determined on a separate, consolidated, combined, group or unitary basis, including any penalties and interest in respect thereof, of the Company and the Company’s Subsidiaries (i) pursuant to Treasury Regulation

Section 1.1502-6 or any comparable provision of state, local, or foreign Law with respect to any taxable period beginning before the Closing Date and (ii) pursuant to any guaranty, indemnification, Tax sharing, or similar agreement made on or before the Closing Date relating to the sharing of liability for, or payment of, Taxes; and

(vi) AmTech Capital Management, LLC, a New York limited liability company, or any of its Subsidiaries.

For purposes of this Agreement, in the case of any Straddle Period, (A) the periodic Taxes of the Company and the Company’s Subsidiaries that are not based on income or receipts (e.g., property Taxes) for any Pre-Closing Tax Period shall be computed based upon the ratio of the number of days in the Pre-Closing Tax Period and the number of days in the entire taxable period, and (B) the Taxes of the Company and the Company’s Subsidiaries for any Pre-Closing Tax Period, other than Taxes described in clause (A), shall be computed as if such taxable period ended on the Closing Date.

(b) Purchaser Indemnification Obligations. Subject to the limitations set forth in this Article X, the Purchaser shall indemnify, defend and hold harmless the Stockholders, and any parent, subsidiary, associate, Affiliate, director, officer, stockholder or agent thereof, and their respective Representatives, successors and permitted assigns (all of the foregoing are collectively referred to as the “Stockholder Indemnified Parties”) from and against all Losses which any such party may suffer, sustain or become subject to, to the extent relating to:

(i) any inaccuracy in, or breach of, any representation or warranty made by the Purchaser under this Agreement or any Ancillary Agreement (without regard to any materiality qualifiers contained therein);

(ii) any breach or non-fulfillment of any covenant or agreement on the part of the Purchaser under this Agreement or any Ancillary Agreement; and

(iii) any fees, expenses or other payments incurred or owed by the Purchaser to any counsel, advisor, agent, broker, investment banker or other firm or Person retained or employed in connection with the transactions contemplated by this Agreement.

Section 10.3 Indemnification Procedure.

(a) If any Purchaser Indemnified Party or Stockholder Indemnified Party, as the case may be (such parties, collectively, the “Indemnified Parties”) intends to seek indemnification pursuant to this Article X, such Indemnified Party shall promptly notify the party from whom indemnification is being sought (the “Indemnifying Party”) by providing written notice of such claim to the Indemnifying Party. The Indemnified Party will provide the Indemnifying Party with prompt notice of any third party claim in respect of which indemnification is sought. The failure to provide either such notice will not affect any rights hereunder except to the extent the Indemnifying Party shall have been materially prejudiced as a result of such failure.

(b) If such claim involves a claim by a third party against the Indemnified Party, the Indemnifying Party may, within thirty (30) calendar days after receipt of such notice by the Indemnifying Party and upon notice to the Indemnified Party, assume, through counsel of their own choosing and at their own expense, the settlement or defense thereof, and the Indemnified Party shall reasonably cooperate with them in connection therewith; provided that the Indemnified Party may participate in such settlement or defense through counsel chosen by it at the expense of the Indemnified Party; provided, further, that if the Indemnified Party reasonably determines that representation by the Indemnifying Party’s counsel of the Indemnifying Party and the Indemnified Party may present such counsel with a conflict of interests, then the Indemnifying Party shall pay the reasonable fees and expenses of one Indemnified Party’s counsel. Notwithstanding anything in this Section 10.3(b) to the contrary, the Indemnifying Party may not, without the prior written consent of the Indemnified Party (such consent not to be unreasonably withheld, conditioned or delayed), settle or Compromise any action or consent to the entry of any judgment. So long as the Indemnifying Party is contesting any such claim in good faith, the Indemnified Party shall not pay or settle any such claim without the Indemnifying Party’s consent, such consent not to be unreasonably withheld, conditioned or delayed. If the Indemnifying Party is not contesting such claim in good faith, then the Indemnified Party may conduct and control, through counsel of its own choosing and at the expense of the Indemnifying Party, the settlement or defense thereof, and the Indemnifying Party shall cooperate with it in connection therewith. The failure of the Indemnified Party to participate in, conduct or control such defense shall not relieve the Indemnifying Party of any obligation it may have hereunder.

(c) Notwithstanding anything in Section 10.3(b) hereof to the contrary, the Purchaser Indemnified Parties and the Stockholders shall jointly control and participate in all proceedings taken in connection with any claim related to Taxes of the Company or any of the Company’s Subsidiaries for any Pre-Closing Tax Period. Neither the Purchaser Indemnified Parties nor the Stockholders shall settle any such Tax claim without the prior written consent of the other, which consent shall not be unreasonably withheld, conditioned or delayed.

Section 10.4 Calculation of Indemnity Payments. The amount of any Loss for which indemnification is provided under this Article X shall be net of any insurance amounts when and to the extent actually received by the Purchaser Indemnified Parties with respect to such Loss. Any indemnity payment under this Article X shall be treated as an adjustment to the Purchase Price for Tax purposes to the extent permitted by Tax Law. The amount of any Loss for which indemnification is provided under this

Article X shall be (i) reduced by the amount of the net Tax benefit actually realized by the Indemnified Party by reason of such Loss and (ii) increased to take account of any net Tax cost actually incurred by the Indemnified Party arising from the receipt or accrual of indemnity payments hereunder (i.e., grossed-up for such increase). For purposes of calculating Losses hereunder with respect to determining whether the Losses exceed the Deductible for purposes of Section 10.6(a), any materiality or Material Adverse Effect qualifications in the representations, warranties, covenants and agreements shall be ignored.

Section 10.5 Relation of Indemnity to Earn-out Payments. The Purchaser may withhold any Earn-out Payments otherwise due to be paid, but only on a several and not joint basis, if there is any Outstanding Claim as against an Indemnifying Party or Parties, in an amount equal to the Outstanding Claim until such claim is resolved under the terms hereof.

Section 10.6 Indemnification Amounts.

(a) Notwithstanding any provision to the contrary contained in this Agreement, neither the Stockholders on one hand, nor the Purchaser on the other hand, shall be obligated to indemnify the Purchaser Indemnified Parties or the Stockholder Indemnified Parties, as the case may be, for any Losses pursuant to this Article X unless and until the dollar amount of all Losses incurred in the aggregate by such Purchaser Indemnified Parties or Stockholder Indemnified Parties, as applicable, exceeds $200,000 (the “Deductible”), in which case the Stockholders or the Purchaser, as the case may be, will only be obligated to indemnify the Purchaser Indemnified Parties or the Stockholder Indemnified Parties, as the case may be, for the total amount of Losses in excess thereof; provided, that in no event shall the aggregate indemnification obligations of the Stockholders or the Purchaser, as the case may be, pursuant to Section 10.2 hereof exceed $3,250,000 (the “Indemnification Cap”); provided, further, that notwithstanding the foregoing, the Purchaser Indemnified Parties’ and Stockholder Indemnified Parties’ rights to seek indemnification hereunder for any Losses due to, resulting from or arising out of the following shall not be subject to, the Deductible or Indemnification Cap limits contained in this Section 10.6:

(i) fraud, intentional misconduct or intentional misrepresentation of the Purchaser, the Stockholders or the Company;

(ii) any breach by the Purchaser, the Stockholders or the Company of any of the covenants or agreements contained in this Agreement;

(iii) any breach by the Company or any of the Stockholders of any representations and warranties referred to in Section 10.1(a)(i) hereof; or

(iv) the items set forth in Section 10.2(a)(iii), (iv), (v) or (vi) hereof.

Any indemnification amounts paid in connection with the matters referred to in Section 10.6(a)(i), (ii), (iii) or (iv) hereof shall not be counted towards or included in the determination of the Indemnification Cap; provided, however, that any Indemnifying Party’s total liability under this Article X arising out of, relating to, or involving any of the matters referred to in Section 10.6(a)(i), (ii), (iii) or (iv) hereof shall not exceed in the aggregate the sum of $17,500,000 plus the aggregate value (calculated at the time of payment pursuant to the terms of this Agreement) of any and all Earn-out Payments actually paid or withheld in accordance with Section 10.5 hereof.

(b) For purposes of clarification and notwithstanding anything to the contrary in this Agreement, in no event and under no circumstance shall any Stockholder be liable for more than its, his or her share of (i) the Purchase Price plus (ii) any and all Earn-out Payments actually paid or withheld in accordance with Section 10.5 hereof.

Section 10.7 Exclusive Remedy. The parties hereto agree that the indemnity provisions set forth in this Article X shall be the sole monetary remedy of the Purchaser, the Company and the Stockholders after the Closing for any breach of the representations, warranties or covenants contained in this Agreement.

Section 10.8 Authorization of the Stockholder Representative.

(b) The Purchaser shall be entitled to rely exclusively upon the communications of the Stockholder Representative relating to the foregoing as the communications of the Stockholders.

(c) Each Stockholder, by its approval of this Agreement, makes, constitutes and appoints the Stockholder Representative as such Stockholder’s true and lawful attorney-in-fact for and in such Stockholder’s name, place, and stead and for its use and benefit, to prepare, execute, certify, acknowledge, swear to, file, deliver, or record any and all agreements, instruments or other documents, and to take any and all actions, that are within the scope and authority of the Stockholder Representative provided for in this Section 10.8. The grant of authority provided for in this Section 10.8(c) is coupled with an interest and is being granted, in part, as an inducement to the parties hereto to enter into this Agreement and shall be irrevocable and survive the death, incompetency, bankruptcy or liquidation of any Stockholder and shall be binding on any successor thereto.

(d) In the event the Stockholder Representative becomes unable to perform his responsibilities hereunder or resigns from such position, the Stockholder (acting by the vote of the Stockholders who immediately prior to the Closing held at least a majority of the Company Shares held by all Stockholders) shall select another representative to fill the vacancy of the Stockholders Representative, and such substituted representative shall be deemed to be a Stockholder Representative for all purposes of this Agreement and the Ancillary Agreements.
