THIS STOCK PURCHASE AGREEMENT (this “Agreement”) is made and entered into as of the 25th day of October, 2006, by and among PDF Solutions, Inc., a Delaware corporation (the “Acquiror”), all of the stockholders and holders of warrants to purchase the stock of Si Automation S.A., a company organized under the laws of France (the “Company”), as well as certain persons having a right to receive stock of the Company, all of which are listed on Exhibit A (the “Selling Stockholders”) acting severally but not jointly, and Société Générale Asset Management Alternative Investments (the “Stockholders’ Representative”).

RECITALS

WHEREAS, the Selling Stockholders own or have warrants to purchase an aggregate of 1,886,906 shares of the Company, which amount includes the ordinary shares to be issued upon the net exercise of Company Warrants (as defined below) at the Closing (the “Shares”), divided into 1,886,906 ordinary shares, €1.00 par value per share, which constitute 100% of the issued and outstanding shares of capital stock of the Company together with all of the Shares subject to outstanding warrants or other rights to purchase shares of capital stock of the Company, in each case at the date hereof (excluding any ordinary shares of the Company held by the Company).

WHEREAS, the persons designated on Exhibit A as “Warrant Holders” (the “Warrant Holders”) are the beneficial and record owners of 100% of the outstanding warrants to purchase capital stock of the Company issued by the Company (the “Company Warrants”) in the proportions as set forth on Exhibit A.

WHEREAS, as a result of the exercise of the Company Warrants, a maximum of 1,000 new shares may be issued at or prior to Closing.

WHEREAS, the Selling Stockholders desire to sell to the Acquiror, and the Acquiror wishes to purchase from the Selling Stockholders, all Shares held by the Selling Stockholders for the purchase price and upon the terms and conditions set forth herein (the “Purchase”).

WHEREAS, in connection with the Purchase, the Acquiror and certain employees of the Company, namely ▇▇▇▇▇▇▇ Moustiés, ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇▇ and ▇▇▇▇▇▇▇ ▇▇▇▇▇▇ (the “Designated Employees”) desire to enter or amend certain agreements.

AGREEMENT

NOW THEREFORE, in consideration of the premises and the mutual covenants and agreements hereinafter contained, the parties, intending to be legally bound hereby agree as follows:

SECTION ONE

1. The Purchase.

1.1 Purchase and Sale of the Shares. Upon the terms and subject to the conditions of this Agreement, at the Closing (as defined below) each Selling Stockholder, acting

severally and not jointly, shall sell to the Acquiror or a wholly owned subsidiary of the Acquiror, free and clear of any and all liens, and the Acquiror or a wholly owned subsidiary of the Acquiror shall purchase from each Selling Stockholder, the Shares owned (or issuable upon the net exercise of Company Warrants as provided herein) by such Selling Stockholder set forth opposite such Selling Stockholder’s name on Exhibit A.

1.2 Purchase Price. The aggregate purchase price to be paid by the Acquiror for the Shares shall be an amount equal to US$30,000,000, as adjusted by the Purchase Price Adjustment (as defined below) (as so adjusted, the “Purchase Price”), to be comprised of the following:

(a) US$30,000,000 (the “Enterprise Value”) to be paid at Closing as follows:

(i) 70% of the Enterprise Value shall be paid in cash in U.S. dollars (together with the adjusted Net Cash amount to be paid pursuant to clause (b) immediately below, the “Closing Cash Consideration”); and

(ii) 30% of the Enterprise Value shall be paid in shares of common stock of the Acquiror, par value $0.001 per share (the “Acquiror Stock”), based on the average of (1) the average reported closing price for such securities on the NASDAQ National Market, or any other major national reporting or quotation system on which the Acquiror Stock may be listed or quoted after the date of this Agreement (the “NASDAQ”) for the ten (10) trading days ending one (1) trading day prior to the date of this Agreement and (2) the average reported closing price for such securities on the NASDAQ for the ten (10) trading days ending one (1) trading day prior to the Closing Date (such average stock price shall be referred to as the “Closing Average Stock Price,” such amount of shares shall be referred to as the “Closing Stock Consideration”); and

(b) An amount equal to the Net Cash (as hereinafter defined) as adjusted by the Working Capital Adjustment (as hereinafter defined), minus the Company Transaction Expenses incurred or accrued (whether billed or unbilled) but not paid prior to the Closing Date, and minus the Transfer Taxes, (each as hereinafter defined), in cash in U.S. dollars (it being understood that to the extent such adjusted amount is negative, the Closing Cash Consideration will be reduced on a dollar for dollar basis).

1.3 Purchase Price Adjustment.

(a) The “Purchase Price Adjustment” shall mean the sum of the following amounts: (i) the Net Cash as adjusted by the Working Capital Adjustment, (ii) less the amount of the Company Transaction Expenses (as hereinafter defined) incurred or accrued (whether billed or unbilled) but not paid prior to the Closing Date, and (iii) less the amount of the Transfer Taxes.

(b) The “Working Capital Adjustment” shall mean the adjustment to the Purchase Price set forth herein as follows: The Purchase Price shall be adjusted downward on a dollar for dollar basis to the extent the Net Asset Amount (as hereinafter defined) reflected on the unaudited balance sheet of the Company as of June 30, 2006 prepared by the Company in

-2-

accordance with French generally accepted accounting principles (“French GAAP”) and reconciled to be in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) (the “Reference Balance Sheet”) exceeds the Net Asset Amount reflected on the unaudited balance sheet of the Company as of the Closing Date, which shall be prepared by the Acquiror in accordance with this Agreement and reconciled to be in accordance with U.S. GAAP applied on a basis consistent with reconciliation of the Reference Balance Sheet (the “Closing Balance Sheet”). The Purchase Price shall be adjusted upward on a dollar for dollar basis to the extent the Net Asset Amount (as hereinafter defined) reflected on the Reference Balance Sheet is less than the Net Asset Amount reflected on the Closing Balance Sheet. The “Net Asset Amount” shall mean the difference between the book value of the Assets (as hereinafter defined) and Liabilities (as hereinafter defined) of the Company as reflected in the Reference Balance Sheet or the Closing Balance Sheet, as applicable, which difference shall be stated in U.S. dollars on the basis of the exchange rate quoted by Citibank in New York at the opening of business on the date of payment to the Selling Stockholders or the Acquiror of the difference between the Estimated Adjustment and the Final Adjustment pursuant to this section.

(c) The “Assets” shall mean all of the assets of the Company other than (i) any components of Net Cash, (ii) any assets that were purchased during the period beginning on June 30, 2006 and ending on July 18, 2006, which are not listed on Schedule 1.3(c) and (iii) any assets that were purchased during the period beginning on July 18, 2006 and ending on the Closing Date without the written consent of the Acquiror, unless such assets in the aggregate were purchased for consideration of €50,000 or less.

(d) The “Liabilities” shall mean all of the liabilities of the Company other than (i) any components of Net Cash, and (ii) any liabilities for Company Transaction Expenses incurred or accrued (whether billed or unbilled) but not paid prior to the Closing Date.

(e) “Net Cash” shall mean the Cash (as hereinafter defined) and Cash Equivalents (as hereinafter defined), plus the amount of the Aggregate Exercise Price (as hereinafter defined), less Indebtedness (as hereinafter defined) of the Company at the Closing Date, it being understood that this amount could be a negative number that would result in a decrease to the Purchase Price.

(f) “Cash” shall mean the cash (disponibilités) and bank deposits as reflected in bank statements and certificates of deposit less escrowed amounts or other restricted cash balances and less the amounts of any unpaid checks, drafts and wire transfers issued on or prior to the date of determination, calculated in accordance with French GAAP applied using the same accounting methods, practices, principles, policies and procedures, with consistent classifications, judgments and valuation and estimation methodologies that were used in the preparation of the Company’s audited Financial Statements for the most recent fiscal year end as if such accounts were being prepared and audited as of a fiscal year end, it being understood that in no event shall shares of the Company’s capital stock held by the Company be included in Cash, with a reconciliation to be in accordance with U.S. GAAP. Without limiting the generality of the foregoing, Cash shall include any cash proceeds from the exercise of Company Warrants on or prior to the Closing.

-3-

(g) “Cash Equivalents” shall mean the consolidated Cash and any short-term, highly liquid investments and marketable securities that are both readily convertible to known amounts of cash and having such maturity that they present insignificant risk of changes in value because of changes in interest rates, such as net VAT credit, Treasury bills, commercial paper, money market funds, and any other cash equivalents of the Company and its Subsidiaries (such as latent capital gains estimated as at the Closing Date on the basis of the corresponding stock price of such investments as at the Closing Date) as of the open of business on the Closing Date and any credit of the Company against the Acquiror with respect to any Accountant Fees (as hereinafter defined) pursuant to Section 6.11(c) to the extent already paid by the Company or accounted as Indebtedness, it being understood that in no event shall shares of the Company’s capital stock held by the Company be included in Cash Equivalents.

(h) “Indebtedness” of any person shall mean, without duplication, (i) the principal, accreted value, accrued and unpaid interest, prepayment and redemption premiums or penalties (if any), unpaid fees or expenses and other monetary obligations in respect of (A) indebtedness of such person for money borrowed and (B) indebtedness evidenced by notes, debentures, bonds or other similar instruments for the payment of which such person is responsible or liable; (ii) all obligations of such person issued or assumed as the deferred purchase price of property (including shares or Intellectual Property rights), all conditional sale obligations of such person and all obligations of such person under any title retention agreement (but excluding trade accounts payable and other accrued current liabilities arising in the ordinary course of business (other than the current liability portion of any indebtedness for borrowed money)); (iii) all obligations of such person under leases required to be capitalized in accordance with French GAAP reconciled to be in accordance with U.S. GAAP; (iv) all obligations of such person for the reimbursement of any obligor on any letter of credit, banker’s acceptance or similar credit transaction; (v) all obligations of such person under interest rate or currency swap transactions (valued at the termination value thereof); (vi) all obligations of the type referred to in clauses (i) through (v) of any other person for the payment of which such first person is responsible or liable, directly or indirectly, as obligor, guarantor, surety or otherwise, including guarantees of such obligations; and (vii) all obligations of the type referred to in clauses (i) through (vi) of any other persons secured by (or for which the holder of such obligations has an existing right, contingent or otherwise, to be secured by) any lien on any property or asset of such first person (whether or not such obligation is assumed by such person). Without limiting the generality of the foregoing, Indebtedness shall specifically include the amount of any outstanding government research loans, including the loan from Agence Nationale de Valorisation de la Recherche (ANVAR) pursuant to the loan agreement number A0405055 J dated 28 September 2004 (the “ANVAR Loan Agreement” and together with the other outstanding government research loan agreements, the “Governmental Loan Agreements”), up to the actual amounts paid out to the Company under such Government Loan Agreements at the date at which such Indebtedness is calculated and to the extent such amounts are not the subject of a waiver under such Government Loan Agreements (including clause 3.5 of the ANVAR Loan Agreement).

(i) The “Transfer Taxes” shall mean the amount of transfer Taxes (as hereinafter defined) and stamp duties payable by the Acquiror as a result of the transfer of the Shares under this Agreement including those contemplated by Section 6.18.

-4-

1.4 Closing.

The Closing shall take place at the offices of ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇▇ LLP, ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, or at such other location as the parties agree.

1.5 Actions at the Closing.

(e) A certified copy of the minutes of the Management Board meeting at which resolutions have been passed to amend the Bylaws of the Company effective as of the Closing to increase the share capital associated with the Company Warrants being net exercised immediately prior to the Closing.

1.6 Payment. At the Closing, the Acquiror shall pay the Estimated Purchase Price (as hereinafter defined) as follows:

(a) Holdback. The Acquiror shall retain the Holdback to satisfy the Purchase Price true up set forth in Section 1.7. The “Holdback” shall mean US$3,000,000 of the Closing Cash Consideration.

(b) Escrow Amounts. 10% of the Estimated Cash Consideration, 10% of the Estimated Stock Consideration (rounded to the nearest whole share), $500,000 in cash and US$75,000 in cash, representing the Selling Stockholders’ portion of the estimated fees and expenses of the Arbiter (as hereinafter defined) (the “Arbiter Costs”), shall be placed in Escrow as provided in Section 9 solely for the purpose of satisfying the Selling Stockholders’

-6-

indemnification obligations under Section 9, the payment of any shortfall in the Holdback (as hereinafter defined) under Section 1.7 and the payment of the Arbiter Costs (the “Warranty Escrow Fund”).

(c) Closing Payments to Selling Stockholders. Subject to Sections 1.6(d), (e) and (f), the remaining Estimated Cash Consideration and Estimated Stock Consideration after the payments set forth in Section 1.6(b) (the “Remaining Cash” and the “Remaining Stock,” respectively), less the Holdback, less the Selling Stockholders Advisors Fees (as hereinafter defined) and less the Stockholders’ Representative Expenses Reserve (as hereinafter defined) shall be paid to the Selling Stockholders as follows: each Selling Stockholder (including Warrant Holders) shall receive:

(i) an amount of cash, rounded to the nearest fifth decimal, equal to (I) the number of Shares being delivered by such Selling Stockholder at the Closing (which number shall include any Shares underlying Company Warrants held by such Selling Stockholder) multiplied by (II) the quotient of (x) the Remaining Cash, less the cash portion of the Holdback, less the Selling Stockholders Advisors Fees, less the Stockholders’ Representative Expenses Reserve, divided by (y) the aggregate number of Shares (including Shares underlying Company Warrants) being purchased by the Acquiror from all Selling Stockholders (including Warrant Holders) at the Closing, less (III) an amount of cash equal to the aggregate exercise price payable upon exercise of any Company Warrants and any Call Option Agreement (as defined in Section 5.2) by such Selling Stockholder at the Closing (the aggregate such exercise price payable with respect to all Company Warrants with respect to the vested and exercisable Shares thereunder as of the Closing shall be referred to as the “Aggregate Exercise Price”), plus (IV) the value of any fractional shares resulting from the calculation of the number of shares of Acquiror Stock set forth in Section 1.6(c)(ii), based on the Closing Average Stock Price, and any amount of cash equal to the aggregate exercise price to be received upon exercise of any Call Option Agreement; and

(ii) a number of shares of Acquiror Stock, rounded to the nearest whole share (with fractional shares paid in cash as set forth in Section 1.6(c)(i)), equal to (I) the number of Shares being delivered by such Selling Stockholder at the Closing (which number shall include any Shares underlying Company Warrants) multiplied by (II) the quotient of (x) the Remaining Stock, less the stock portion of the Holdback, divided by (y) the aggregate number of Shares (including Shares underlying Company Warrants) being purchased by the Acquiror from all Selling Stockholders (including Warrant Holders) at the Closing.

(d) Minority Selling Stockholders Escrow Equivalent. The Minority Selling Stockholders (i) shall not contribute to the Warranty Escrow Fund and shall be paid directly any amount which otherwise would have been paid by them into the Warranty Escrow Fund (the “Minority Selling Stockholders Escrow Equivalent”) and (ii) shall not be required to fund the Arbiter Costs and shall be paid directly any amount which otherwise would have been paid by them to fund the Arbiter Costs (the “Minority Selling Stockholders Arbiter Costs Equivalent”). As a result, in the event any payment from the Purchase Price is to be made to the Selling Stockholders and 10% of this amount is simultaneously to be paid to the Warranty Escrow Fund under this Agreement, the Selling Stockholders other than the Minority Selling Stockholders (the “Escrow Selling Stockholders”) agree that any such amount payable (whether

-7-

in cash or in Acquiror Stock) to them shall be reduced in the aggregate by the Minority Selling Stockholders Escrow Equivalent which shall be paid to the Warranty Escrow Fund by each Escrow Selling Stockholder in proportion to its share in the number of Shares delivered by the Escrow Selling Stockholders to the Acquiror at the Closing. The Escrow Selling Stockholders also agree that any amount payable to them from the Cash Consideration at the Closing shall be reduced in the aggregate by the Minority Selling Stockholders Arbiter Costs Equivalent which shall be paid to the Arbiter Costs Fund by each Escrow Selling Stockholder in proportion to its share in the number of Shares delivered by the Escrow Selling Stockholders to the Acquiror at the Closing.

(e) Escrow Contribution Cash and Stock Election. Initially, the total property contributed to the Warranty Escrow Fund shall be a mixture of cash and Acquiror Stock, which, based on the Closing Average Stock Price, has an aggregate value equal to 10% of the Closing Consideration. The Acquiror shall contribute property with respect to each Escrow Selling Stockholder initially having an aggregate value equal to such Escrow Selling Shareholder’s ratable portion (based on the value of the Closing Consideration such Escrow Selling Shareholder receives at Closing compared to the total value of the Closing Consideration received by all of the Escrow Selling Stockholders at Closing) of the total property contributed to the Warranty Escrow Fund. Certain Selling Stockholders have elected to substitute cash for Acquiror Stock or vice versa in order to fund its ratable portion of the Warranty Escrow Fund as set forth on Exhibit D, provided that for Selling Stockholders who have elected to substitute Acquiror Stock for cash, any fractional share of Acquiror Stock shall be contributed in cash (the “Escrow Contribution Spreadsheet”). As such, each Escrow Selling Stockholder shall have an ongoing proportionate interest (their “Escrow Proportionate Interest”) in the property that may be held from time to time in the Warranty Escrow Fund based on the value of the property such Escrow Selling Stockholder initially elected to have contributed with respect to it by the Acquiror compared to the total value of the property initially deposited in the Warranty Escrow Fund by the Acquiror. Upon any release of escrowed property from the Warranty Escrow Fund to the Escrow Selling Stockholders, each Escrow Selling Stockholder that elected to have cash contributed with into the Warranty Escrow Fund with respect to it by the Acquiror shall receive cash first up to the amount of such Escrow Selling Stockholder’s Escrow Proportionate Interest and then Acquiror Stock for any balance owed on such Escrow Selling Stockholder’s Escrow Proportionate Interest. Conversely, upon any release of escrowed property from the Warranty Escrow Fund to the Escrow Selling Stockholders, each Escrow Selling Stockholder that elected to have Acquiror Stock contributed to the Warranty Escrow Fund on behalf of it by the Acquiror shall receive Acquiror Stock first up to the amount of such Escrow Selling Stockholder’s Escrow Proportionate Interest and then cash for any balance owed on such Escrow Selling Stockholder’s Escrow Proportionate Interest. Upon any release of escrowed property from the Warranty Escrow Fund to the Escrow Selling Stockholders, the Acquiror Stock in the Warrant Escrow Fund shall be valued for purposes of determining the foregoing allocations between cash and Acquiror Stock at average reported closing price for such securities on the NASDAQ for the ten (10) trading days ending one (1) trading day prior to such release. As a result, the amount of the Closing Cash Consideration and Closing Stock Consideration shall be appropriately adjusted for each Escrow Selling Stockholder who elects to substitute cash for stock (or vice versa) in the Warrant Escrow.

-8-

(f) Liquidation Preference for Top Management. The Selling Stockholders have agreed to give ▇▇▇▇▇▇▇ Moustiés, ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ and ▇▇▇▇ ▇▇▇▇▇▇ (collectively, the “Top Management”) a certain liquidation preference with respect to their Shares in a recent amendment to the Shareholders Agreement. This liquidation preference is reflected in the purchase price allocation spreadsheet attached as Exhibit A (the “Purchase Price Allocation Spreadsheet”). As a result, the amount of the Closing Cash Consideration and Closing Stock Consideration shall be appropriately adjusted for each Selling Stockholder to reflect the agreed upon liquidation preference for the Top Management. Each Selling Stockholder’s proportionate interest in the cash and proportionate interest in the stock as set forth in the Purchase Price Allocation Spreadsheet shall be referred to herein as such Selling Stockholder’s “Closing Consideration Proportionate Interest” of cash or stock, as the case may be.

(g) Estimated Purchase Price and Allocation Spreadsheet. Not later than two business days prior to the Closing Date, the Selling Stockholders other than FCPI Soge Innovation 3, FCPI Soge Innovation 5, FCPI Soge Innovation 6 (collectively, “SGAM AI”) shall cause the Company to provide to the Acquiror its good faith estimates (based on the most current information available to the Company) of the Closing Balance Sheet, the Net Cash, the Working Capital Adjustment, the Company Transaction Expenses, the Transfer Taxes and the resulting estimated Purchase Price Adjustment, together with a spreadsheet showing what portion of the total consideration each Selling Stockholder is entitled to receive hereunder. The Stockholders’ Representative and the Acquiror shall seek to agree, in good faith, upon an estimate of the Purchase Price Adjustment (the “Estimated Purchase Price Adjustment”) and the resulting estimated Purchase Price (the “Estimated Purchase Price”), estimated Closing Cash Consideration (the “Estimated Cash Consideration”) and estimated Closing Stock Consideration (the “Estimated Stock Consideration”); provided, however, in the event that the Stockholders’ Representative and the Acquiror fail or are unable to so agree on the Estimated Purchase Price Adjustment, the Estimated Purchase Price Adjustment shall be the Estimated Purchase Price Adjustment furnished by the Company (which shall be deemed to be the Estimated Purchase Price Adjustment for purposes hereof) and any dispute concerning the amounts thereof after the Closing shall be resolved in accordance with Section 1.7. Each of the Purchase Price Adjustment and the Estimated Purchase Price Adjustment shall be calculated applying the currency exchange rate as quoted by Citibank in New York as of the date of the applicable payment to be made hereunder (the “Applicable Exchange Rate”).

1.7 Purchase Price True Up.

(a) Following the Closing, the Purchase Price shall be adjusted as provided herein to reflect the difference between the Estimated Purchase Price Adjustment and the Purchase Price Adjustment, as finally determined pursuant to this Section 1.7. Within 60 days following the Closing Date, the Acquiror shall deliver to the Stockholders’ Representative the Closing Balance Sheet, the calculation of the Working Capital Adjustment, Net Cash, Transfer Taxes and Company Transaction Expenses together with a calculation of the Purchase Price Adjustment (derived from the Closing Balance Sheet and/or such other books and records of the Company and its Subsidiaries as are applicable).

-9-

(b) Subject to the execution of customary auditors’ confidentiality and liability release undertakings (covering “secret d’affaires”) by the Stockholders’ Representative on its behalf and on behalf of its representatives (including its auditors), the Acquiror shall provide the Stockholders’ Representative and its auditors with full and prompt access to the books and records and relevant personnel of the Acquiror, the Company and its Subsidiaries and their statutory auditors for the purpose of reviewing the Closing Balance Sheet, the Working Capital Adjustment, the Net Cash, the Transfer Taxes and the Company Transaction Expenses. Such access shall be (x) during normal business hours and upon reasonable advance notice, and (y) up until the final determination of the Purchase Price Adjustment. The Selling Stockholders shall use such access for the sole purpose of the determination of the Purchase Price Adjustment. In addition, the Selling Stockholders’ auditors shall have full access to the accounting books and records, work papers, schedules or additional documents prepared, used or otherwise generated by the statutory auditors of the Company and its Subsidiaries.

(c) The Closing Balance Sheet and calculation of the Purchase Price Adjustment delivered by the Acquiror to the Stockholders’ Representative shall be conclusive and binding upon all the parties to this Agreement unless the Stockholders’ Representative, within sixty (60) days after delivery thereof, notifies the Acquiror in writing that the Stockholders’ Representative disputes any of the amounts set forth therein, specifying the nature of the dispute and the basis therefor. The Stockholders’ Representative and the Acquiror shall in good faith attempt to resolve any dispute and, if they so resolve all disputes, the Closing Balance Sheet and the Purchase Price Adjustment, as amended to the extent necessary to reflect the resolution of the dispute, shall be conclusive and binding on all of the parties to this Agreement. If the Stockholders’ Representative and the Acquiror do not reach agreement in resolving the dispute within twenty (20) calendar days after notice is given by the Stockholders’ Representative to the Acquiror pursuant to the second preceding sentence, the parties shall submit the dispute to a mutually satisfactory partner in the San ▇▇▇▇ office of the accounting firm of Deloitte & Touche LLP or, if no partner at such firm will act, to a partner at such other nationally recognized independent accounting firm which is mutually agreeable to the Stockholders’ Representative and the Acquiror (the “Arbiter”) for resolution. If the Stockholders’ Representative and the Acquiror cannot agree on the selection of a partner at an independent accounting firm to act as Arbiter, the parties shall resolve such dispute through arbitration conducted in accordance with the rules of the American Arbitration Association with a single arbitrator to act as the Arbiter, who’s decision shall be conclusive and binding on all of the parties to this Agreement. Promptly, but no later than twenty (20) calendar days after acceptance of his or her appointment as Arbiter, the Arbiter shall determine (it being understood that in making such determination, the Arbiter shall be functioning as an expert and not as an arbitrator), based solely on written submissions by the Acquiror and the Stockholders’ Representative, and not by independent review, only those issues in dispute and shall render a written report as to the resolution of the dispute and the resulting computation of the Purchase Price Adjustment which shall be conclusive and binding on the parties. All proceedings conducted by the Arbiter shall take place in San Jose, California. In resolving any disputed item, the Arbiter (x) shall be bound by the provisions of this Section 1.7 and (y) may not assign a value to any item greater than the greatest value for such items claimed by either party or less than the smallest value for such items claimed by either party. The fees, costs and expenses of the Arbiter shall be allocated to and borne by the Acquiror and the Selling Stockholders based on the inverse of the percentage that the Arbiter’s determination (before such allocation) bears to the

-10-

total amount of the total items in dispute as originally submitted to the Arbiter. For example, if the Stockholders’ Representative decides to submit a dispute hereunder to arbitration, and the Arbiter ultimately awards 70% of the amount disputed by the Stockholders’ Representative, then the Selling Stockholders will bear 30% of the fees, costs and expenses of the Arbiter (in addition to their own fees, costs and expenses), and the Acquiror will bear 70% of the Arbiter’s fees, costs and expenses (in addition to its own fees, costs and expenses).

(d) Upon final determination of the Purchase Price Adjustment, if the Purchase Price as adjusted by the Purchase Price Adjustment is less than the Purchase Price as adjusted by the Estimated Purchase Price Adjustment (the “Purchase Price Excess”), the Escrow Selling Stockholders shall pay to the Acquiror the amount, if any, by which the Purchase Price Excess exceeds the Holdback, together with interest thereon from the Closing Date to the date of payment thereof as determined below, by giving the requisite release instructions to the Escrow Agent to permit the Acquiror to receive such amount of cash out of the Warranty Escrow Fund, Any amounts payable by the Escrow Selling Stockholders under this clause shall be payable solely out of the Warranty Escrow Fund. The Selling Stockholders’ Representative, on behalf of the Escrow Selling Stockholders, shall give the requisite release instructions to the Escrow Agent promptly, but no later than five (5) business days after such final determination. If the Purchase Price Excess is less than the Holdback, the Acquiror shall pay to the Selling Stockholders or the Paying Agent, on behalf of Selling Stockholders, the amount of such difference in cash, together with interest thereon from the Closing Date to the date of payment thereof as determined below. Any such payment by the Acquiror shall be made promptly, but no later than five (5) business days after such final determination; provided that 10% of the cash to otherwise be paid to the Selling Stockholders shall be deposited into the Warranty Escrow Fund (subject to Section 1.6(d)). Each Selling Stockholder will receive their Closing Consideration Proportionate Interest in any such remaining cash and stock payable to them.

(e) Upon final determination of the Purchase Price Adjustment, if the Purchase Price as adjusted by the Purchase Price Adjustment is more than the Purchase Price as adjusted by the Estimated Purchase Price Adjustment, the Acquiror shall pay in cash to the Selling Stockholders or the Paying Agent, on behalf of the Selling Stockholders, the sum of (A) the amount of such difference and (B) the Holdback, promptly, but no later than five (5) business days after such final determination, together with interest thereon from the Closing Date to the date of payment thereof as determined below; provided that 10% of the cash to otherwise be paid to the Selling Stockholders shall be deposited into the Warranty Escrow Fund (subject to Section 1.6(d)). Each Selling Stockholder will receive their Closing Consideration Proportionate Interest in any such remaining cash and stock payable to them.

(f) For the purposes of this Section 1.7, interest will be payable at the “prime” rate, as announced by The Wall Street Journal, Eastern Edition, from time to time to be in effect, calculated based on a 365 day year and the actual number of days elapsed.

1.8 Purchase of Common Stock; Net Exercise of Warrants. The Shares to be purchased by the Acquiror at the Closing shall consist solely of the Company’s common stock, and at such time there shall be no other outstanding securities of or rights to purchase or otherwise acquire securities of the Company. Accordingly, each Warrant Holder hereby irrevocably elects to exercise the entire vested portion of their Company Warrants effective at the

-11-

Closing, with the exercise price to be deemed paid by them on a net exercise basis pursuant to Section 1.6(c) and hereby confirms that any unvested portion of Company Warrants not so net exercised at the Closing shall terminate at the Closing in accordance with the terms of the warrants as modified hereby. As such, all options, warrants or other rights to purchase or acquire shares of the Company capital stock shall have been exercised or terminated on or prior to the Closing.

1.9 Securities Act Exemption. The Acquiror Stock to be issued pursuant to this Agreement shall not be registered under the Securities Act of 1933, as amended (“Securities Act”), in reliance upon the exemption contained in Section 4(2) of the Securities Act and Regulation D and Regulation S promulgated thereunder and in reliance upon the representations and warranties of the Selling Stockholders contained in Article 3 below.

1.10 Stock Restrictions. The certificates representing the shares of Acquiror Stock issued pursuant to this Agreement shall bear a restrictive legend or legends (and stop transfer orders shall be placed against the transfer thereof with the Acquiror’s transfer agent), stating substantially as follows:

(a) “THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISPOSITION MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933.”

(b) Any legend required by the securities laws of any state.

1.11 Withholding. Each of the Acquiror and the Company shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of Company Capital Stock such amounts as may be required to be deducted or withheld therefrom under the U.S. Internal Revenue Code of 1986, as amended, or any provision of U.S. state or local law, or any non-U.S. laws or regulations or under any other applicable legal requirement. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the person to whom such amounts would otherwise have been paid.

SECTION TWO

2. Representations and Warranties Relating to the Company.

In this Agreement, any reference to a “Material Adverse Effect” with respect to any entity or group of entities means any event, change or effect that is or has a substantial likelihood to be, materially adverse to the condition (financial or otherwise), properties, assets, liabilities, business, operations or results of operations of such entity and its subsidiaries, taken as a whole, or will prevent or materially delay consummation of the Purchase or otherwise will prevent such entity and its subsidiaries from performing their obligations under this Agreement,

-12-

except for any event, change or effect that results from or arises in connection with (i) any changes or events affecting general economic or business conditions, (ii) any changes or events affecting the industries in which such entity or any of its subsidiaries operates, (iii) the effect of the public announcement or pendency of this Agreement and the transactions contemplated hereby, or (iv) the taking of any action required by the terms of this Agreement.

In this Agreement, any reference to a party’s “knowledge” means, (i) for the Acquiror, such party’s actual knowledge after reasonable inquiry of officers, directors and other employees of the Acquiror reasonably believed to have knowledge of the matter in question; and (ii) for the Company or the Selling Stockholders, the Company’s or the Selling Stockholders’ actual knowledge after reasonable inquiry of the Top Management (as hereinafter defined).

Except as specifically disclosed in a document dated as of the date of this Agreement and delivered by the Selling Stockholders to the Acquiror prior to the execution and delivery of this Agreement referencing the appropriate section and subsection numbers to which such exceptions or disclosure relates (the “Company Disclosure Schedule”) (provided that items disclosed in one section or subsection of this Agreement shall be deemed disclosed under any other section or subsection of this Agreement where the applicability of such disclosure should be reasonably apparent to the Acquiror under the circumstances), the Selling Stockholders, other than SGAM AI and other than the Minority Selling Stockholders, hereby severally but not jointly represent and warrant to the Acquiror as of the date hereof and as of the Closing Date as follows:

2.1 Organization; Subsidiaries; Officers, Directors, Members of the Management Board and Members of the Supervisory Board. Each of the Company and each subsidiary of the Company, if any (each a “Subsidiary”), is a corporation duly organized, validly existing and in good standing under the laws of its jurisdiction of organization. Each of the Company and each Subsidiary has the requisite corporate power and authority and all necessary governmental approvals to own, lease and operate its properties and to carry on its business as now being conducted and as proposed to be conducted, except where the failure to have such power, authority and governmental approvals would not, individually or in the aggregate, have a Material Adverse Effect on Company. Each of the Company and each Subsidiary is duly qualified or licensed as a foreign corporation to do business, and is in good standing, in each jurisdiction where the character of the properties owned, leased or operated by it or the nature of its business makes such qualification or licensing necessary, except for such failures to be so qualified or licensed and in good standing that would not, individually or in the aggregate, have a Material Adverse Effect on the Company. A true and complete list of all the Subsidiaries, together with the jurisdiction of incorporation of each Subsidiary, is set forth in Section 2.1 of the Company Disclosure Schedule. The Company is the owner of all outstanding shares of capital stock of each Subsidiary and all such shares are duly authorized, validly issued, fully paid and nonassessable. All of the outstanding shares of capital stock of each Subsidiary are owned by the Company free and clear of all liens, charges, claims, encumbrances or rights of others. There are no outstanding subscriptions, options (including options de souscription ou d’achat d’actions), warrants, puts, calls, rights, exchangeable or convertible securities or other commitments or agreements of any character relating to the issued or unissued capital stock or other securities of any Subsidiary, or otherwise obligating the Company or any Subsidiary to issue, transfer, sell, purchase, redeem or otherwise acquire any such securities. Except as set forth in Section 2.1 of the Company Disclosure Schedule, the Company does not directly or

-13-

indirectly own any equity or similar interest in, or any interest convertible into or exchangeable or exercisable for, any equity or similar interest in, any corporation, partnership, limited liability company, joint venture or other business association or entity.

2.2 Applicable Organizational Documents. The Company has delivered a true and correct copy of the bylaws (statuts) or equivalent organizational documents (the “Bylaws”), of the Company and the Articles of Incorporation or other Charter documents (“Charter”) and Bylaws of each Subsidiary, as applicable, each as amended to date, to the Acquiror. Neither the Company nor any Subsidiary is in violation of any of the provisions of its Charter, Bylaws or equivalent organizational documents, as applicable (the “Applicable Organizational Documents”).

2.3 Capital Structure.

(a) As of the date hereof, the capital stock of the Company consists of 1,885,906 outstanding shares of Common Stock (the “Company Capital Stock”).

All outstanding shares of Company Capital Stock are duly authorized, validly issued, fully paid and non-assessable and are not subject to preemptive rights created by statute, the Company’s Bylaws, or any agreement to which the Company is a party or by which it is bound. All shares of Company Capital Stock and Company Warrants were issued and, if applicable, repurchased (in the case of shares that were outstanding and repurchased by the Company or any stockholder of the Company) in compliance with all applicable laws, rules, or regulations, and were issued, transferred and repurchased (in the case of shares that were outstanding and repurchased by the Company or any stockholder of the Company) in accordance with any right of first refusal or similar right or limitation known to the Company or the Selling Stockholders, including those in the Company’s Bylaws. There are no outstanding shares of Company Capital Stock that constitute unvested restricted stock or that are otherwise subject to a repurchase or redemption right.

The Company has never granted any Company Warrants to any U.S. residents. True and complete copies of all agreements and instruments relating to or issued under the Company Warrants have been provided to the Acquiror and such agreements and instruments have not been amended, modified or supplemented, and there are no agreements to amend, modify or supplement such agreements or instruments from the forms thereof provided to the Acquiror.

There are no agreements to which the Company is a party relating to the registration, sale or transfer (including agreements relating to rights of first refusal, co-sale rights or “drag-along” rights) of any Company Capital Stock. As a result of the Purchase, the Acquiror will be the sole record and beneficial holder of all issued and outstanding Company Capital Stock and all rights to acquire or receive any shares of Company Capital Stock, whether or not such shares of Company Capital Stock are outstanding.

2.4 Authority. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly authorized by all necessary corporate action on the part of the Selling Stockholders. This Agreement has been duly executed and delivered by the Selling Stockholders and assuming due authorization, execution and delivery by the Acquiror, constitutes the valid and binding obligation of the Selling Stockholders enforceable against the Selling Stockholders in accordance with its terms.

-15-

There is no judgment, decree or order against the Company or any Subsidiary or, to the best knowledge of the Company or the Selling Stockholders, any of their respective officers, directors, members of the Management Board or members of the Supervisory Board (in their capacities as such), that could prevent, enjoin, or materially alter or delay any of the transactions contemplated by this Agreement, or that would reasonably be expected to have a Material Adverse Effect on the Company.

(e) No loss or expiration of any Intellectual Property licensed to the Company or any Subsidiary is pending or reasonably foreseeable or, to the knowledge of the Company, threatened.

Neither the Company nor any Subsidiary has brought any action, suit or proceeding for infringement of Intellectual Property or breach of any license or agreement involving Intellectual Property against any third party. The Company and the Selling Stockholders are not aware of any infringement of the Company’s Intellectual Property by a third party and are not aware of any third party action to impair the Company’s rights in the Intellectual Property, including without limitation, through the filing of patents that could impair the Company’s ability to practice its current or anticipated business.

Selling Stockholder understands the lack of liquidity and restrictions on transfer of the Acquiror Stock and that this investment is suitable only for a person or entity of adequate financial means that has no need for immediate liquidity of this investment and that can afford a total loss of its investment.

(ii) Upon making any payment to an Indemnified Person hereunder for any indemnification claim pursuant to this Section Nine, the indemnifying person shall be subrogated, to the extent of such payment, to any rights which such Indemnified Person may have against any third-person with respect to the subject matter underlying such indemnification claim and all of the Indemnified Persons with respect to such claim shall assign any such rights to the indemnifying person with respect to such claim.

9.4 SGAM AI Special Earnout. In the event there are no Damages suffered by the Acquiror Indemnified Persons incurred by reason of or in connection with (i) any misrepresentation, breach of, or default in connection with, any of the representations, warranties, covenants or agreements of the Selling Stockholders contained in this Agreement or any closing certificates furnished by the Selling Stockholders or the Company at the Closing, or (ii) the matters disclosed in Section 2.8(b)(1) of the Company Disclosure Schedule, then SGAM AI shall receive as additional earnout consideration hereunder the amount deposited on its behalf into the Warranty Escrow Fund (the “SGAM AI Special Earnout”) as and at the same time as the other Selling Stockholders’ portions of the Warranty Escrow Fund shall be released to them pursuant to the Escrow Agreement. To the extent there are any such Damages, the amount of the SGAM AI Special Earnout to be paid to SGAM AI shall be reduced by the amount equal to the total amount payable to the Acquiror Indemnified Persons from the Warranty Escrow Fund under this Agreement and the Escrow Agreement with respect to such Damages multiplied by the quotient of (x) the value of the Closing Consideration received by SGAM AI at the Closing divided by (y) the aggregate value of the Closing Consideration received by the Escrow Selling Stockholders at the Closing. The amount of such reduction in the SGAM AI Special Earnout shall be returned to the Acquiror out of the Warranty Escrow Fund as and at the same time as the other Selling Stockholders’ portions of the Warranty Escrow Fund are distributed to the Acquiror pursuant to the Escrow Agreement. The balance of any SGAM AI Special Earnout, if any, shall be paid to SGAM AI as additional earnout consideration as and at the same time as the other

-64-

Escrow Selling Stockholders’ portions of the Warranty Escrow Fund shall be released to them pursuant to the Escrow Agreement.

9.5 Escrow Period. The Warranty Escrow Fund shall remain in existence until the Initial Escrow Termination Date. The Warranty Escrow Property remaining in the Warranty Escrow Fund at the Initial Escrow Termination Date shall be paid to the Escrow Selling Stockholders, except for (i) the amount of any bona fide claim for Damages outstanding as of such date, 70% of which amount shall be cash in U.S. dollars based on the Applicable Exchange Rate as of the Initial Escrow Termination Date and 30% of which amount shall be shares of Acquiror Stock based on the Closing Average Stock Price (the “Outstanding Claims Reserve”) and (ii) an amount of cash equal to US$100,000 for potential Tax Damages arising during the indemnification period for Taxes remaining after the Initial Escrow Termination Date (the “Tax Escrow Fund” and together with the Outstanding Claims Reserve, the “Special Reserve Escrow Fund”). Any balance of the Special Reserve Escrow Fund remaining at the expiration of the Final Escrow Termination Date shall be paid to the Escrow Selling Stockholders, except for the amount of any bona fide claim for Damages outstanding as of such date, 70% of which amount shall be cash in U.S. dollars based on the Applicable Exchange Rate as of the Final Escrow Termination Date and 30% of which amount shall be shares of Acquiror Stock based on the Closing Average Stock Price, which amount shall not be released until final resolution of such claims (the “Escrow Period”). As soon as all such claims have been resolved, the Escrow Agent shall deliver to the Escrow Selling Stockholders all property remaining in the Warranty Escrow Fund and not required to satisfy such claims. Deliveries of Warranty Escrow Property to the Escrow Selling Stockholders pursuant to this Section 9.5 and the Escrow Agreement shall be made in proportionate amounts of cash and share as described in Section 1.6(e). In the event that there is not sufficient cash remaining in the Warranty Escrow Fund to satisfy the foregoing requirements of this Section 9.5, then such remaining cash will be applied first and the balance shall be in shares of Acquiror Stock.

9.6 Distributions; Voting.

(a) Any cash or shares of the Acquiror Stock or other equity securities issued or distributed by the Acquiror (including shares issued upon a stock split) (“New Property”) in respect of the Warranty Escrow Shares that have not been released from the Warranty Escrow Fund shall be added to the Warranty Escrow Fund and become a part thereof.

(b) Each Escrow Selling Stockholder shall have voting rights with respect to that number of Warranty Escrow Shares contributed to the Warranty Escrow Fund on behalf of such Escrow Selling Stockholder (and on any voting securities added to the Warranty Escrow Fund in respect of such Warranty Escrow Shares) so long as such Warranty Escrow Shares or other voting securities are held in the Warranty Escrow Fund. As the record holder of such shares, the Escrow Agent shall vote such shares in accordance with the instructions of the Escrow Selling Stockholders having the beneficial interest therein and shall promptly deliver copies of all proxy solicitation materials to such Escrow Selling Stockholders. The Acquiror shall show the Acquiror Stock contributed to the Warranty Escrow Fund as issued and outstanding on its balance sheet.

-65-

9.7 Method of Asserting Claims. All claims for indemnification by the Acquiror, or any other Indemnified Person pursuant to this Section 9 shall be made in accordance with the provisions of the Escrow Agreement. The Acquiror Indemnified Persons shall be entitled to receive the amount of any Damages as follows: 70% out of the Escrow Cash and 30% out of the Escrow Shares. For purposes of determining the value of the Escrow Shares to be used to reimburse any claim for Damages, the Escrow Shares shall be valued at the average reported closing price for such securities on the NASDAQ for the ten (10) trading days ending one (1) trading day prior to the date such claim is finally resolved and determined to be payable out of the Warranty Escrow Fund.

9.8 Tax Characterization of Indemnification Payments. All indemnity payments made by the Selling Stockholders to an Acquiror Indemnified Person shall be treated for all tax purposes as adjustments to the consideration paid with respect to the Shares.

9.9 Representative of the Stockholders; Power of Attorney.

(a) Upon the Closing, and without further act of any stockholder, each Selling Stockholder hereby appoints Société Générale Asset Management Alternative Investments as its agent and attorney-in-fact to act for and on behalf of the Selling Stockholders, to act in the capacity of the Stockholders’ Representative hereunder, to give and receive notices and communications on behalf of the Selling Stockholders, to enter into the Reiterative Deed of Sale, to enter into and perform the Escrow Agreement, to authorize delivery to the Acquiror of Escrow Property or other property from the Warranty Escrow Fund in satisfaction of claims by the Acquiror or any other Indemnified Person, to object to such deliveries, to agree to, negotiate, enter into settlements and compromises of, and demand arbitration and comply with orders of courts and awards of arbitrators with respect to such claims, and to take all actions necessary or appropriate in the judgment of the Stockholders’ Representative for the accomplishment of the foregoing in its absolute discretion.

(b) The Stockholders’ Representative shall not be liable or responsible for any act he may do or omit to do hereunder save in the event of gross negligence or willful misconduct of the Stockholders’ Representative. Without limiting the generality of the foregoing, the Stockholders’ Representative shall not incur any liability with respect to any action taken or suffered by him in reliance upon any note, direction, instruction (including instructions of all or part of the Selling Stockholders), consent, statement or other document believed by him to be genuinely and duly authorized, nor for any action or inaction in reliance in good faith upon advice of legal counsel. The Stockholders’ Representative will not be required to make any verification in order to assess the authenticity or the accuracy of the documents transmitted to the Stockholders’ Representative under this mandate.

(c) Each of the Selling Stockholders, the Acquiror and the Stockholders’ Representative hereby agrees that (i) the assignment of the Stockholders’ Representative under this Agreement shall terminate on the Final Escrow Termination Date, (ii) the assignment of the Stockholders’ Representative under this Agreement may be terminated at any time by the Stockholders’ Representative prior to the expiry of Final Escrow Termination Date by giving written notice of such termination to the other Parties; provided, however, that the Stockholders’ Representative appoints another stockholders’ representative who shall

-66-

substitute for him and who shall comply with the full requirements of such mandate. Such right to termination shall not give rise to damages to the parties hereof. If the Stockholders’ Representative shall die, become disabled or otherwise be unable to fulfill his responsibilities hereunder, former Selling Stockholders whose aggregate pro-rata share in the Company share capital immediately prior to Closing exceeds 50% shall, within twenty (20) business days after such death or disability, appoint a successor to the Stockholders’ Representative and immediately thereafter notify the Acquiror of the identity of such successor. Any such successor shall succeed the Stockholders’ Representative as Stockholders’ Representative hereunder.

(d) Each of the Selling Stockholders other than the Stockholders’ Representative hereby irrevocably agrees:

(i) to contribute (pro-rata its number of Shares delivered on Closing) on first written demand of the Stockholders’ Representative to any and all out of pocket expenses, cost or disbursements reasonably incurred by the Stockholders’ Representative in connection with its appointment and agrees that such contribution may be paid to the Stockholders’ Representative directly out of any amount to be paid from the Escrow Fund to the Selling Stockholders;

(ii) to appoint and instruct legal advisers, as proposed by the Stockholders’ Representative, to advise and represent the Stockholders’ Representative in any legal and/or administrative proceedings brought against the Selling Stockholders or any of them;

(iii) jointly and severally with each other Selling Stockholder to indemnify and hold harmless the Stockholders’ Representative upon first written demand from and against any Damages incurred or suffered by the Stockholders’ Representative in connection with its appointment (save for any such Damages which arises from gross negligence or willful misconduct on the part of the Stockholders’ Representative);

(iv) to inform immediately the Stockholders’ Representative of any change in his address; and

(v) to transfer (pro-rata based on its Closing Consideration Proportionate Interest) a total amount of $95,000 from the Closing Cash Consideration to an escrow account opened with the Escrow Agent in the name of the Acquiror pursuant to the Escrow Agreement in order to finance the costs, disbursements and out-of-pocket expenses which may be incurred by the Stockholders’ Representative under its assignment (the “Stockholders’ Representative Expenses Reserve”) and enter into any escrow agreement with the Escrow Agent, on behalf of the Selling Stockholders to that extent. The escrow account shall be U.S. dollar denominated, interest bearing and located in the United States (the “Stockholders’ Representative Escrow Account”). The Escrow Agent shall release any amount from the Stockholders’ Representative Expenses Reserve to the Stockholders’ Representative upon simple request from the Stockholders’ Representative accompanied with the relevant invoice. The Stockholders’ Representative Escrow Account shall be held by the Escrow Agent until the Final Escrow Termination Date. After this period, any balance of the Stockholders’ Representative Expenses Reserve remaining on the Stockholders’ Representative Escrow Account shall be repaid by the Escrow Agent to Selling Stockholders, save for any outstanding amount necessary

-67-

to finance reasonable future costs, disbursements and out-of-pocket expenses which may be incurred by the Stockholders’ Representative in relation with any claim outstanding at such date, which shall be paid to the Stockholders’ Representative directly and shall not be refundable.

(e) The Stockholders’ Representative hereby agrees:

(i) to forward to each other Seller a copy of each notification received by it of a claim by the Acquiror hereunder, within twenty (20) business days of the Stockholders’ Representative’s receipt of the same;

(ii) during such time as one or more claims by the Acquiror remains outstanding, to provide each Selling Stockholder, on a quarterly basis, with a summary written report describing the progress of each such outstanding claim; and

(iii) to comply with any written request of Selling Stockholders whose aggregate pro-rata number of Shares delivered at Closing exceeds 50% regarding the conduct of any claim, provided always that the Stockholders’ Representative shall not be obliged to comply with any such request unless it has received pre-payment, or security reasonably satisfactory to it for the payment, of any out of pocket expenses, costs or disbursements which it reasonably estimates are likely to arise in connection with such compliance.
