Each share of Target Series C Preferred Stock issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive (A) a fraction of a share of Acquiror Common Stock equal to the Closing Series C Exchange Ratio, plus (B) in the event any Additional Consideration Shares are issuable from time to time, a fraction of a share equal to the Additional Consideration Exchange Ratio applicable to the Target Series C Preferred Stock;

(ii) Series B. Each share of Target Series B Preferred Stock issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive (A) a fraction of a share of Acquiror Common Stock equal to the Closing Series B Exchange Ratio, plus (B) in the event any Additional Consideration Shares are issuable from time to time, a fraction of a share equal to the Additional Consideration Exchange Ratio applicable to the Target Series B Preferred Stock;

(iii) Series A. Each share of Target Series A Preferred Stock issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive (A) a fraction of a share of Acquiror Common Stock equal to the Closing Series A Exchange Ratio, plus (B) in the event any Additional Consideration Shares are issuable from time to time, a fraction of a share equal to the Additional Consideration Exchange Ratio applicable to the Target Series A Preferred Stock; and

(iv) Common. Each share of Target Common Stock issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive (A) a fraction of a share of Acquiror Common Stock equal to the Closing Common Stock Exchange Ratio, plus (B) in the event any Additional Consideration Shares are issuable from time to time, a fraction of a share equal to the Additional Consideration Exchange Ratio.

(v) Distributions of Merger Consideration in Accordance with Target Certificate of Incorporation. The determination of the respective exchange ratios with respect to each class of Target Capital Stock shall be made in accordance with and subject to the terms of Section 2 of Article IV.B in the Target Certificate of Incorporation, with the “Fair Market Value” (as defined in Section 8 of Article IV.B in the Target Certificate of Incorporation) of the shares of Acquiror Common Stock being issued in the Merger being equal to the Acquiror Stock Price. Without limiting the generality of the foregoing, in calculating the respective exchange ratios the following methodology consistent with the Target Certificate of Incorporation shall be employed:

(1) Liquidation Preference. (i) The holders of the Target Series A Preferred Stock shall be entitled to receive, prior and in preference to any payment or distribution and setting apart for payment or distribution of any shares of Acquiror Common Stock to the holders of the Target Common Stock, a number of shares of Acquiror Common Stock for each share of Series A Preferred Stock then held by them equal to $0.40 divided by the Acquiror Stock Price; (ii) the holders of the Target Series B Preferred Stock shall be entitled to receive, prior and in preference to any payment or distribution and setting apart for payment or distribution of any shares of Acquiror Common Stock to the holders of the Target Common Stock, a number of shares of Acquiror Common Stock for each share of Series B Preferred Stock then held

by them equal to $1.25 divided by the Acquiror Stock Price; and (iii) the holders of the Target Series C Preferred Stock shall be entitled to receive, prior and in preference to any payment or distribution and setting apart for payment or distribution of any shares of Acquiror Common Stock to the holders of the Target Common Stock, a number of shares of Acquiror Common Stock for each share of Series C Preferred Stock then held by them equal to $0.725 divided by the Acquiror Stock Price.

(2) Participation Amounts and Caps. After giving effect to the foregoing liquidation preferences, the remaining shares of Acquiror Common Stock available for distribution to the holders of Target Capital Stock shall be distributed ratably among the holders of the Target Series A Preferred Stock, Target Series B Preferred Stock, Target Series C Preferred Stock and Target Common Stock in proportion to the number of shares of Target Capital Stock then held by them (on an as-converted to Target Common Stock basis); provided that (i) a holder of a share Target Series A Preferred Stock shall not be entitled to receive a number of shares of Acquiror Common Stock per share of Target Series A Preferred Stock pursuant to the Merger which exceeds $1.20 divided by the Acquiror Stock Price; (ii) a holder of a share of Target Series B Preferred Stock shall not be entitled to receive a number of shares of Acquiror Common Stock per share of Target Series B Preferred Stock pursuant to the Merger which exceeds $2.50 divided by the Acquiror Stock Price; and (iii) a holder of a share of Target Series C Preferred Stock shall not be entitled to receive a number of shares of Acquiror Common Stock per share of Target Series B Preferred Stock pursuant to the Merger which exceeds $2.18 divided by the Acquiror Stock Price, in each case, including amounts received pursuant to the liquidation preference described above.

(3) Status of Stock Determined at Effective Time. While conversion of Target Preferred Stock into Target Common Stock shall be permitted until immediately prior to the Effective Time in accordance with and subject to the Target Certificate of Incorporation, the status of a share of Target Capital Stock as Target Preferred Stock or Target Common Stock immediately prior to the Effective Time shall be final and binding on the holder thereof at and following the Effective Time for purposes of determining the consideration to be received by the holder thereof.

(4) Escrow Shares. The setting aside of Escrow Shares on behalf of a Target stockholder shall be deemed to be in satisfaction of the respective liquidation preference and participation rights described above and in the Target Certificate of Incorporation, such that any claims made against the Escrow Fund that reduce the amount actually received by a Target stockholder shall not give rise to any claim by a Target stockholder for adjustment to such stockholder’s exchange ratio(s).

(5) Calculation Certificate. The calculations of the respective Base Consideration Exchange Ratios (Closing Series C Exchange Ratio, Closing Series B Exchange Ratio, Closing Series A Exchange Ratio and Closing Common Stock Exchange Ratio), including the related calculations of Total Fully Diluted Target Shares, Expense Adjustment Amount, Base Consideration Merger Shares, Closing Escrow Shares (including the portions thereof that constitute Primary Escrow Shares and Secondary Shares) and the like, shall be set forth in a Schedule 1.6(a), in the form attached hereto, to be finalized and executed by Acquiror, Target and the Stockholder Representative at or

prior to the Closing. Solely for illustrative purposes, the Example Schedule 1.6(a) attached hereto on the date of this Agreement includes certain pro forma calculations to demonstrate the operation of the provisions of this Section 1.6. The Example Schedule 1.6(a) attached hereto is solely illustrative and does not modify the operation of this Section 1.6 or the Target Certificate of Incorporation.

(vi) [Reserved]

(vii) Target or Acquiror Owned Stock. At the Effective Time, by virtue of the Merger and without any action on the part of Acquiror, Merger Sub, Target or the Former Target Stockholders, each share of Target Capital Stock, if any, owned by Acquiror or Target, or any subsidiary of Acquiror or Target, immediately prior to the Effective Time, shall be automatically cancelled and extinguished without any conversion thereof.

(c) Additional Consideration Distributions and Procedures.

(i) Determination of Additional Consideration.

(A) Distributions. The Interim Target Product Revenues and the Target Product Revenues shall be assessed on a cumulative basis by Acquiror as of the final day of each of the Interim Revenue Period and the Target Revenue Period, respectively. If and to the extent (1) Interim Target Product Revenues would result in the issuance of Interim Additional Consideration Shares (determined pursuant to the definition of such term above) and/or (2) Target Product Revenues would result in the issuance of Final Additional Consideration Shares (determined pursuant to the definition of such term above), then as soon as practicable, which shall not be sooner than the 15th business day nor later than the 30th business day following the earlier of (i) the resolution of any dispute pursuant to Section 1.6(c)(iii), (ii) the expiration of the time period during which the Stockholder Representative may deliver the Dispute Notice pursuant to Section 1.6(c)(ii) without the delivery of any such Dispute Notice or (iii) the written and unconditional waiver by the Stockholder Representative of the time period during which the Stockholder Representative may deliver the Dispute Notice pursuant to Section 1.6(c)(ii), Acquiror shall issue or caused to be issued to the Former Target Stockholders the requisite number of Interim Additional Consideration Shares or Final Additional Consideration Shares, as applicable, which shall be issuable to Former Target Stockholders in accordance with the Interim Additional Consideration Exchange Ratio and/or the Final Additional Consideration Exchange Ratio. Each date on which such Additional Consideration Shares are issued to the Former Target Stockholders is referred to herein as a “Distribution Date.”

(B) Final Additional Consideration Share Deficit. If and to the extent Target Product Revenues as of the end of the Target Revenue Period result in a Final Additional Consideration Share Deficit, such deficit shall be Damages and Acquiror shall be entitled to proceed against the Escrow Fund in accordance with Article VIII and the Escrow Agreement, and the Additional Consideration Exchange Ratio shall be accordingly determined by taking into account such deficit.

(ii) Reporting. No later than the tenth business day following the filing of Acquiror’s Quarterly Report on Form 10-Q for the fiscal quarter in which the Interim Revenue Period and the Target Revenue Period respectively ends, Acquiror shall prepare (or cause to be prepared) and deliver to the Stockholder Representative a final calculation of (1) Interim Target Product Revenues or Target Product Revenues, as applicable, including a determination of whether any, and if so how many, Interim Additional Consideration Shares or Final Additional Consideration Shares, as applicable, would be issuable, and (2) the related Interim Consideration or Final Additional Consideration Exchange Ratios, together with such documentation as may be reasonably necessary to support such calculations. After receipt of each such calculation from Acquiror, the Stockholder Representative shall have the right, at the expense of the Former Target Stockholders and upon not less than ten (10) business days prior notice to Acquiror, to meet with Acquiror to discuss Acquiror’s calculation, shall have reasonable access during normal business hours to inspect the records, working papers, schedules and other documentation (which Acquiror shall maintain for a period not less than one year after the end of any fiscal year with respect to each such calculation) used or prepared by Acquiror in connection with the preparation of such calculation, in any such case solely for the purpose of verifying such calculation. Unless the Stockholder Representative gives notice of its disagreement (a “Dispute Notice”) with Acquiror’s determination of such Interim Target Product Revenues, Target Product Revenues, Interim Consideration Exchange Ratio or Final Consideration Exchange Ratio, as applicable, detailing the amount, nature and detailed basis of such dispute within 10 days after the delivery of the applicable calculation, Acquiror’s determination shall be final, conclusive and binding for all purposes.

(iii) Dispute Resolution. In the event of such a dispute and delivery of the Dispute Notice, Acquiror and the Stockholder Representative shall first use diligent good faith efforts to resolve such dispute. If they are unable to resolve the dispute within 30 calendar days after delivery of the Dispute Notice, then the dispute shall be submitted to an independent, nationally recognized United States accounting firm (which need not be one of the “Big Four” accounting firms, but shall not be Ernst & Young LLP or the Acquiror’s then-current outside auditor) selected in writing by the Stockholder Representative and Acquiror, which firm shall select one of its partners (the “Arbitrator”) to determine matters in dispute. Acquiror and the Stockholder Representative shall instruct the Arbitrator to make a decision as promptly as practicable but in no event later than 30 days after acceptance of such appointment. A determination by the Arbitrator as to the resolution of any dispute (including all procedural matters) shall be binding and conclusive upon the parties. A judgment of the determination made by the Arbitrator pursuant to this paragraph may be entered into and enforced by any court having jurisdiction thereover. Each party shall bear its fees and expenses with respect to any proceeding under this paragraph, and the fees and expenses of the Arbitrator in connection with the resolution of disputes pursuant to this paragraph shall be paid by the non-prevailing party, who shall be determined by the Arbitrator.

(iv) Additional Consideration Share Rights Not Transferable. No Former Target Stockholder may sell, exchange, transfer or otherwise dispose of his, her or its right to receive the Additional Consideration Shares, other than by the laws of descent and distribution or succession, and any transfer in violation of this Section 1.6(c)(iv) shall be null and void and shall not be recognized by Acquiror, Merger Sub or Target; provided that assignments shall be permitted by a Former Target Stockholder to any person that is a subsidiary, parent, member, partner, limited partner, retired partner or shareholder of such Former Target

Stockholder, and who agrees to become obligated to all of the obligations of the transferor with respect to such transferred rights (including this restriction on transfer).

(v) Imputed Interest. In the event any Additional Consideration Shares are required to be issued to the Former Target Stockholders pursuant to the terms and provisions hereof, Acquiror shall determine and report to the appropriate tax authorities the amount of interest allocable to such shares (as provided by Section 483 of the Code and related Section 1.483-4 of the Treasury Regulations promulgated thereunder), if any, with such interest amount being referred to herein as the “Imputed Interest Amount.” The parties acknowledge and agree that no separate cash payment will be made by Acquiror with respect to an Imputed Interest Amount and, as a consequence, a portion of the Additional Consideration Shares (the “Interest Shares”) would be treated as being paid to the Former Target Stockholders in satisfaction of the Imputed Interest Amount. Acquiror shall have no liability whatsoever with respect to any tax obligations with respect to any Imputed Interest Amount.

(d) Target Options, Warrants, Restricted Stock.

(i) Cancellation of Target Stock Options. Neither the Target Stock Plan nor any Target Option shall be assumed by Acquiror or Merger Sub in connection with the Merger. Accordingly, effective as of the Effective Time the vesting schedules of all outstanding Target Options shall be accelerated in full in accordance with the Target Stock Plan, and each Target Option that has not been exercised prior to the Effective Time shall terminate as of the Effective Time and be of no further force and effect.

(ii) Cancellation of Target Warrants. At the Effective Time, each outstanding Target Warrant shall be cancelled and extinguished. Prior to the Effective Time, Target shall take all action necessary to effect the transactions anticipated by this Section 1.6(d) under all Target Warrant agreements; provided that any payments or grant of consideration by Target in connection with the foregoing (including any agreements or other promises) shall require the prior written consent of Acquiror.

(iii) Restricted Stock Vesting. With respect to any shares of Target Capital Stock issued and outstanding immediately prior to the Effective Time that are unvested and subject to a repurchase right, risk of forfeiture or other condition under any applicable stock restriction agreement or other agreement with Target (“Target Restricted Stock”), Target shall take all action to provide for the acceleration and vesting in full (including termination of any repurchase right, risk of forfeiture or other similar condition) of such Target Restricted Stock prior to the Effective Time.

(e) [Reserved]

(f) Merger Consideration. Subject to adjustment pursuant to Section 1.6(k), the maximum number of shares of Acquiror Common Stock that may be issued in exchange for the acquisition by Acquiror of all outstanding Target Capital Stock shall be the Base Consideration Merger Shares plus the Interim Additional Consideration Shares, if any, plus the Final Additional Consideration Shares, if any.

(g) Withholding Taxes. All Acquiror Common Stock issuable pursuant to Section 1.6 shall be subject to, and reduced by, the number of shares of Acquiror Common Stock determined by dividing (x) the amount, if any, required by law to be withheld with respect to any state, federal and foreign withholding taxes incurred by or applicable to (i) a Former Target Stockholder (and not previously paid by or on behalf of such Former Target Stockholder or Target) in connection with the Merger, (ii) the acquisition of Target Capital Stock upon the exercise of Target Options, (iii) the acceleration of the vesting of any Target Option or any Target Capital Stock or (iv) the payment of a bonus in the form of Target Capital Stock or with respect to any bonus provided to any holder of a Target Option with respect to or in connection with the exercise of any Target Option, by (y) the Acquiror Stock Price.

(h) Former Target Stockholder Loans. In the event that any Former Target Stockholder has outstanding loans from Target as of the Effective Time, which loans shall be listed on a Schedule 1.6(h) as of the date hereof and updated within three (3) business days prior to the Closing, the Acquiror Common Stock issuable to such Former Target Stockholder pursuant to Section 1.6 shall be reduced by the number of shares of Acquiror Common Stock determined by dividing (x) the outstanding principal plus accrued interest of such Former Target Stockholder’s loan as of the Effective Time by (y) the Acquiror Stock Price. Such Former Target Stockholder shall be solely responsible with respect to any taxes which may become payable with respect to such note cancellation.

(i) Cancellation of Treasury Stock and Acquiror-Owned Stock. All shares of Target Capital Stock that are owned by Target as treasury stock or by Acquiror or Merger Sub immediately prior to the Effective Time shall automatically be cancelled and retired and shall cease to exist and no consideration shall be delivered in exchange therefor.

(j) Capital Stock of Merger Sub. Each share of Common Stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one validly issued, fully paid and nonassessable share of Common Stock of the Surviving Corporation. Each stock certificate of Merger Sub evidencing ownership of any such shares shall continue to evidence ownership of such shares of capital stock of the Surviving Corporation.

(k) Adjustments to Exchange Ratios. The applicable exchange ratio for each series and class of outstanding Target Capital Stock shall be appropriately adjusted to reflect fully the effect of any stock split, reverse split, stock dividend (including any dividend or distribution of securities convertible into Acquiror Common Stock or Target Capital Stock), reorganization, recapitalization or other like change with respect to Acquiror Common Stock or Target Capital Stock occurring after the date hereof and prior to the Effective Time. No exchange ratio shall be adjusted, nor shall any additional consideration of any nature be issuable hereunder, on account of any consideration (in any form whatsoever) received by Target from the date hereof to the Effective Time pursuant to the sale, exercise, conversion or exchange of any Target Capital Stock, Target Options or Target Warrants.

(l) Fractional Shares. No fraction of a share of Acquiror Common Stock will be issued in connection with the Merger, but in lieu thereof each holder of shares of Target Capital Stock who would otherwise be entitled to a fraction of a share of

Acquiror Common Stock (after aggregating all fractional shares of Acquiror Common Stock to be received by such holder at the Closing, upon a Distribution Date of Additional Consideration Shares, or upon the release of the Escrow Shares) shall receive from Acquiror an amount of cash (rounded to the nearest whole cent) equal to the product of (i) such fraction and (ii) the Acquiror Stock Price.

(m) No Liability. Notwithstanding anything to the contrary herein, Acquiror shall not be liable for any error or delay on the part of the Exchange Agent or the Escrow Agent except to the extent proximately caused by Acquiror without fault of Target or the Target Stockholder Representative.

1.7 Dissenting Shares. Notwithstanding anything contained herein to the contrary, other than the following provisions of this Section 1.7, any Dissenting Shares shall not be converted into Acquiror Common Stock but shall instead be converted into the right to receive such consideration as may be determined to be due with respect to such Dissenting Shares pursuant to Delaware Law. Target shall give Acquiror prompt notice of any demands for appraisal received by Target, withdrawals of such demands, and any other instruments served pursuant to Delaware Law and received by Target and any opportunity to direct all negotiations and proceedings with respect to demands for appraisal under Delaware Law. Target agrees that, except with the prior written consent of Acquiror, or as required under Delaware Law, it will not voluntarily make any payment with respect to, or settle or offer to settle, any such purchase demand. Each holder of Dissenting Shares who, pursuant to the provisions of Delaware Law, becomes entitled to payment of the fair value for shares of Target Capital Stock shall receive payment therefor (but only after the value therefor shall have been agreed upon or finally determined pursuant to such provisions) from the Surviving Corporation. If, after the Effective Time, any Dissenting Shares shall lose their status as Dissenting Shares, then any such shares shall immediately be converted into the right to receive, subject to and in accordance with Section 1.6 and Section 1.8(g), the consideration issuable pursuant to Section 1.6(b) in respect of such shares had such shares never been Dissenting Shares, and Acquiror shall issue and deliver to the holder thereof, at (or as promptly as reasonably practicable after) the applicable time or times specified in Section 1.8, following the satisfaction of the applicable conditions set forth in Section 1.8, the number of shares of Acquiror Common Stock (and cash in lieu of any fractional shares) to which such holder would be entitled in respect thereof under Section 1.6 had such shares never been Dissenting Shares (and all such shares of Acquiror Common Stock shall be deemed for all purposes of this Agreement to have become issuable and deliverable to such holder pursuant to Section 1.6(b)), subject to the deposit of a portion of such Acquiror Common Stock into the Escrow Fund pursuant to Section 1.8 and Article VIII.

1.8 Surrender of Certificates.

(a) Exchange Agent. Equiserve Trust Company N.A., the transfer agent and registrar for the Acquiror Common Stock, shall act as exchange agent (the “Exchange Agent”) in the Merger.

(b) Acquiror to Provide Common Stock and Cash. As soon as practicable, but in no event later than three business days after the Target Capitalization Spreadsheet Submission Date, Acquiror shall make available to the Exchange Agent for exchange

in accordance with this Article I, through such commercially reasonable procedures as Acquiror may adopt, (i) the shares of Acquiror Common Stock issuable pursuant to Section 1.6(b) in exchange for shares of Target Capital Stock outstanding immediately prior to the Effective Time less the number of Closing Escrow Shares to be deposited into an escrow fund (the “Escrow Fund”) pursuant to the requirements of Section 1.8(c)(iv) and Article VIII hereof and (ii) cash in an amount sufficient to permit payment of cash in lieu of fractional shares pursuant to Section 1.6(l).

(c) Exchange Procedures.

(i) Attached as Exhibit I are (A) a form of letter of transmittal (the “Letter of Transmittal”) and (B) instructions for use of the Letter of Transmittal in effecting the surrender of certificates which immediately prior to the Effective Time represented issued and outstanding shares of Target Capital Stock that were converted into the right to receive shares of Acquiror Common Stock (and cash in lieu of fractional shares) pursuant to Section 1.6(b) (such certificates, the “Certificates”) in exchange for certificates (or book entries in the case of shares that have not yet vested) representing such shares of Acquiror Common Stock (and cash in lieu of fractional shares).

(ii) Target shall mail or otherwise deliver the Letter of Transmittal (and the related instructions) and any other documentation required thereby to every holder of record of a Certificate in connection with the Proxy Statement/Prospectus (defined below). Target shall use its commercially reasonable efforts to collect from such holders such Certificates, together with such properly completed and duly executed Letters of Transmittal and any other documentation required thereby, prior to the Closing Date.

(iii) In the case of any Certificate delivered to Acquiror at the Closing, together with a properly completed and duly executed Letter of Transmittal and any other documentation required thereby, within 15 business days after the Target Capitalization Spreadsheet Submission Date, such Certificate shall be cancelled and the Exchange Agent shall send the holder of record of such Certificate (A) a certificate representing the number of whole shares of Acquiror Common Stock (less the number of shares of Acquiror Common Stock to be deposited into the Escrow Fund on such holder’s behalf pursuant to this Section 1.8 and Article VIII) that such holder has the right to receive pursuant to Section 1.6(b) in respect of such Certificate, and (B) any related payment in lieu of fractional shares that such holder has the right to receive pursuant to Section 1.6(l) in respect of such Certificate.

(iv) As soon as practicable, but in no event later than 20 business days after the Target Capitalization Spreadsheet Submission Date, Acquiror shall cause the Exchange Agent to mail the Letter of Transmittal (and the related instructions) to each Former Target Stockholder whose Certificate has not been delivered to Acquiror at the Closing, to the address for such Former Target Stockholder set forth on the Target Capitalization Spreadsheet.

(v) In the case of any Certificate that is not delivered to Acquiror at the Closing, together with a properly completed and duly executed Letter of Transmittal and any other documentation required thereby, then, within 20 business days after the later of the Target Capitalization Spreadsheet Submission Date and the date of delivery of such Certificate to the Exchange Agent, together with such Letter of Transmittal and any other documentation required thereby, the Certificate so

surrendered shall be cancelled and the Exchange Agent shall send the holder of record of such Certificate (A) a certificate representing the number of whole shares of Acquiror Common Stock (less the number of shares of Acquiror Common Stock to be deposited into the Escrow Fund on such holder’s behalf pursuant to this Section 1.8 and Article VIII) that such holder has the right to receive pursuant to Section 1.6(b) in respect of such Certificate, and (B) any related payment in lieu of fractional shares that such holder has the right to receive pursuant to Section 1.6(l) in respect of such Certificate.

(vi) Within 30 business days after the Target Capitalization Spreadsheet Submission Date, and from time to time thereafter as appropriate on account of any Dissenting Shares that shall have lost their status as Dissenting Shares, and subject to and in accordance with the provisions of Article VIII, Acquiror shall cause to be deposited with the Escrow Agent one or more certificates representing the Escrow Shares. The certificate or certificates representing the Escrow Shares shall be registered in the name of (or the name of a nominee of) the Escrow Agent, as escrow agent under the Escrow Agreement (as such term is defined in Section 5.14). Notwithstanding anything contained herein to the contrary, the Closing Escrow Shares shall be withheld from the shares of Acquiror Common Stock issuable to Former Target Stockholders as of immediately prior to the Effective Time pursuant to Section 1.6(b) on a pro rata basis for deposit in the Escrow Fund. The Escrow Shares shall, to the extent possible, be vested shares not subject to any repurchase rights, shall be held in the Escrow Fund and shall constitute security for the indemnification obligations of such Former Target Stockholders pursuant to Article VIII. Upon each Payment Date of Additional Consideration Shares, Acquiror also shall cause Additional Escrow Shares to be deposited into the Escrow Fund in a similar manner. The Escrow Shares shall be held in and distributed from the Escrow Fund in accordance with the provisions of the Escrow Agreement. If the terms of this Agreement conflict in any way with the terms of the Escrow Agreement, then the provisions of this Agreement shall control.

(d) Distributions with Respect to Unexchanged Shares. No dividends or other distributions with respect to Acquiror Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Acquiror Common Stock represented thereby until the holder of record of such Certificate surrenders such Certificate. Subject to applicable law, following surrender of any such Certificate, there shall be paid to the record holder of the certificates representing whole shares of Acquiror Common Stock issued in exchange therefor, without interest, at the time of such surrender, the amount of any such dividends or other distributions with a record date after the Effective Time which previously would have been payable (but for the provisions of this Section 1.8(d)) with respect to such shares of Acquiror Common Stock.

(e) Transfers of Ownership. If any certificate for shares of Acquiror Common Stock is to be issued in a name other than that in which the Certificate surrendered in exchange therefor is registered, it shall be a condition of the issuance thereof that the Certificate so surrendered is properly endorsed and otherwise in proper form for transfer and that the person requesting such exchange will have paid to Acquiror or the Exchange Agent any transfer or other Taxes (as defined in Section 2.13) required by reason of the issuance of a certificate for shares of Acquiror Common Stock in any name other than that of the registered holder of the Certificate surrendered, or established to the satisfaction of Acquiror or the Exchange Agent that such Tax has been paid or is not payable.

(f) No Liability. Notwithstanding anything to the contrary in this Section 1.8, no party hereto or any of their respective agents shall be liable to any person for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar law.

(g) Dissenting Shares. The provisions of this Section 1.8 also shall apply to Dissenting Shares that lose their status as such, except that the obligations of Acquiror under this Section 1.8 shall commence on the date of loss of such status and the holder of such shares shall be entitled to receive in exchange for such shares the number of shares of Acquiror Common Stock to which such holder is entitled pursuant to Section 1.7 hereof (less the number of such shares to be deposited in the Escrow Fund).

(h) Unclaimed Shares. Any amounts of Acquiror Common Stock (and cash in lieu of fractional shares) delivered or made available to the Exchange Agent pursuant to this Section 1.8 and not exchanged for Target Capital Stock within 12 months after the Effective Date pursuant to this Section 1.8 shall be returned by the Exchange Agent to Acquiror. Thereafter any Former Target Stockholders who theretofore have not complied with this Section 1.8 shall be entitled to look to Acquiror (subject to abandoned property, escheat and other similar laws) only as general creditors thereof with respect to any Acquiror Common Stock (and cash in lieu of fractional shares) that may be payable upon due surrender of the Certificates held by them.

1.9 No Further Ownership Rights in Target Capital Stock. All consideration paid or payable in respect of the surrender for exchange of shares of Target Capital Stock in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Target Capital Stock, and there shall be no further registration of transfers on the records of the Surviving Corporation of shares of Target Capital Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article I.

1.10 Lost, Stolen or Destroyed Certificates. In the event any Certificate shall have been lost, stolen or destroyed, Acquiror shall issue or cause to be issued in exchange for such lost, stolen or destroyed Certificate, upon the making of an affidavit of that fact by the holder thereof, such shares of Acquiror Common Stock as may be required pursuant to Section 1.6; provided, however, that Acquiror (i) will require, as a condition precedent to the issuance thereof, that the owner of such lost, stolen or destroyed Certificate agree to indemnify Acquiror and the Surviving Corporation with respect to any claim that may be made against Acquiror, the Surviving Corporation or any of their agents with respect to the Certificate alleged to have been lost, stolen or destroyed and (ii) may require, in Acquiror’s reasonable discretion, that such owner deliver a bond in such sum as Acquiror may reasonably direct as security for the owner’s indemnity obligation under the foregoing clause (i).

1.11 Tax Consequences. It is intended by the parties hereto that the Merger shall constitute a reorganization within the meaning of Section 368 of the Code. No party shall take any action which would, to such party’s knowledge, cause the Merger to fail

to so qualify as a reorganization within the meaning of Section 368 of the Code. Each party has consulted with its own tax advisors with respect to the tax consequences of the Merger.

1.12 Taking of Necessary Action; Further Action. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, properties, rights, privileges, powers and franchises of Target and Merger Sub, the officers and directors of Target and Merger Sub are fully authorized in the name of their respective corporations or otherwise to take, and shall take, all such lawful and necessary action, so long as such action is not inconsistent with this Agreement.

1.13 Approval. The adoption of this Agreement and the approval of the Merger by the stockholders of Target shall constitute approval of this Agreement, the Escrow Agreement and all of the transactions contemplated hereby and thereby, including any alteration of the Target Certificate of Incorporation deemed to have been effected hereby or thereby.

As used herein, “Tax Return” shall mean any return, statement, report or form (including estimated tax returns and reports, withholding tax returns and reports and information returns and reports) required to be filed with respect to Taxes, including any amendment thereof.

2.14 Employee Benefit Plans.

(a) Section 2.14(a) of the Target Disclosure Schedule lists, with respect to Target and any trade or business (whether or not incorporated) which is treated as a single employer with Target (each, an “ERISA Affiliate”) within the meaning of Section 414(b), (c), (m) or (o) of the Code, (i) all employee benefit plans (as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), (ii) each loan to any employee, officer or director and any stock option, stock purchase, phantom stock, stock appreciation right, supplemental retirement, severance, sabbatical, medical, dental, vision care,

disability, employee relocation, cafeteria benefit (Code Section 125) or dependent care (Code Section 129), life insurance or accident insurance plans, programs or arrangements, (iii) all bonus, pension, profit sharing, savings, deferred compensation or incentive plans, programs or arrangements, (iv) other fringe or employee benefit plans, programs or arrangements that apply to senior management of Target and that do not generally apply to all employees, and (v) any current or former employment or executive compensation or severance agreements, written or otherwise, as to which unsatisfied obligations of Target of at least $2,000 remain for the benefit of, or relating to, any present or former employee, Independent Contractor or director of Target (together, the “Target Employee Plans”).

(b) Target has furnished to Acquiror a copy of each of the Target Employee Plans and related plan documents (including trust documents, insurance policies or contracts, employee booklets, summary plan descriptions and other authorizing documents, and any material employee communications relating thereto) and has, with respect to each Target Employee Plan which is subject to ERISA reporting requirements, provided copies of the Form 5500 reports filed for the last three plan years. Any Target Employee Plan intended to be qualified under Section 401(a) of the Code either has obtained from the Internal Revenue Service a favorable determination letter as to its qualified status under the Code, including all amendments to the Code effected by the Tax Reform Act of 1986 and subsequent legislation, or has applied (or has time remaining in which to apply) to the Internal Revenue Service for such a determination letter prior to the expiration of the requisite period under applicable Treasury Regulations or Internal Revenue Service pronouncements in which to apply for such determination letter and to make any amendments necessary to obtain a favorable determination or has been established under a standardized prototype plan for which an Internal Revenue Service opinion letter has been obtained by the plan sponsor and is valid as to the adopting employer. Target has also furnished Acquiror with the most recent Internal Revenue Service determination or opinion letter issued with respect to each such Target Employee Plan, and nothing has occurred since the issuance of each such letter which could reasonably be expected to cause the loss of the tax-qualified status of any Target Employee Plan subject to Code Section 401(a).

has been waived under the regulations to Section 4043 of ERISA) nor any event described in Section 4062, 4063 or 4041 of ERISA has occurred; (vii) no Target Employee Plan is covered by, and neither Target nor any ERISA Affiliate has incurred or expects to incur any liability under Title IV of ERISA or Section 412 of the Code; and (viii) each Target Employee Plan can be amended, terminated or otherwise discontinued after the Effective Time in accordance with its terms, without liability to Acquiror (other than ordinary administrative expenses typically incurred in a termination event). With respect to each Target Employee Plan subject to ERISA as either an employee pension plan within the meaning of Section 3(2) of ERISA or an employee welfare benefit plan within the meaning of Section 3(1) of ERISA, Target has prepared in good faith and timely filed all requisite governmental reports (which were true and correct as of the date filed) and has properly and timely filed and distributed or posted all notices and reports to employees required to be filed, distributed or posted with respect to each such Target Employee Plan.

(d) With respect to each Target Employee Plan, Target has complied with (i) the applicable health care continuation and notice provisions of COBRA and the regulations (including proposed regulations) thereunder, (ii) the applicable requirements of the Family Medical and Leave Act of 1993 and the regulations thereunder and (iii) the applicable requirements of the Health Insurance Portability and Accountability Act of 1996 and the regulations (including proposed regulations) thereunder.

(e) The consummation of the transactions contemplated by this Agreement will not (i) entitle any current or former employee or other service provider of Target or any other ERISA Affiliate to severance benefits or any other payment, except as expressly provided in this Agreement, or (ii) accelerate the time of payment or vesting, or increase the amount of compensation due any such employee or service provider.

(f) There has been no amendment to, written interpretation or announcement (whether or not written) by Target or any other ERISA Affiliate relating to, or change in participation or coverage under, any Target Employee Plan which would increase the expense of maintaining such Plan above the level of expense incurred with respect to that Plan for the most recent fiscal year included in the Target Financial Statements.

(g) Target does not currently maintain, sponsor, participate in or contribute to, nor has it ever maintained, established, sponsored, participated in, or contributed to, any pension plan (within the meaning of Section 3(2) of ERISA) which is subject to Part 3 of Subtitle B of Title I of ERISA, Title IV of ERISA or Section 412 of the Code.

(h) Neither Target nor any other ERISA Affiliate is a party to, or has made any contribution to or otherwise incurred any obligation under, any “multiemployer plan” as defined in Section 3(37) of ERISA.

deductible by reason of Section 280G or Section 404 of the Code or that would be characterized as an “excess parachute payment” within the meaning of Section 280G(b)(1) of the Code. Section 2.14(i) to the Target Disclosure Schedule lists all persons who Target reasonably believes are, with respect to Target and/or any ERISA Affiliate, “disqualified individuals” (within the meaning of Section 280G of the Code and the regulations promulgated thereunder), as determined as of the date hereof.

Target’s standard form of each such agreement has been provided to Acquiror. This Agreement and the transactions contemplated hereby do not and will not violate any such employment agreement, offer letter, Independent Contractor agreement, consulting agreement or termination or severance agreement. Target is in material compliance with all currently applicable federal, state and local laws and regulations respecting employment, non-discrimination in employment, terms and conditions of employment, wages, hours and occupational safety and health and employment practices, and is not engaged in any unfair labor practice. All individuals performing services for Target as Independent Contractors are, and at all times were, properly classified as Independent Contractors pursuant to all applicable regulations, including, but not limited to, I.R.S. Revenue Ruling 87-41, 1987-1 C.B. 296. Target has withheld all amounts required by law or by agreement to be withheld from the wages, salaries and other payments to employees and is not liable for any arrears of wages or any taxes or any penalty for failure to comply with any of the foregoing withholding requirements. Target is not liable for any payment to any trust or other fund or to any governmental or administrative authority, with respect to unemployment compensation benefits, social security or other benefits or obligations for employees (other than routine payments to be made in the normal course of business and consistent with past practice).

insurance claims. There are no claims or controversies pending or, to the knowledge of Target, threatened, between Target and any of its employees or Independent Contractors, which claims or controversies have or could reasonably be expected to result in an action, suit, proceeding, claim, arbitration or investigation before any agency, court or tribunal, foreign or domestic, nor, to the knowledge of Target, is there any basis for any of the foregoing. Target is not a party to any collective bargaining agreement or other labor union contract nor does Target know of any activities or proceedings of any labor union or to organize any such employees. To the knowledge of Target, no employees or Independent Contractors of Target are in violation of any term of any employment contract, patent disclosure agreement, enforceable non-competition agreement, or any enforceable restrictive covenant with a former employer or customer relating to the right of any such employee or Independent Contractor to be employed by or provide services to Target because of the nature of the business conducted or presently proposed to be conducted by Target or to the use of trade secrets or proprietary information of such former employer or customer. No current employees or Independent Contractors of Target have given notice to Target, nor is Target otherwise aware, that any such employee or Independent Contractor intends to terminate his or her employment or service with Target in the reasonably foreseeable future. As of the date hereof, Target has not, and to the knowledge of Target, no other person has, (i) entered into any agreement, contract or instrument that obligates or purports to obligate Acquiror to make an offer of employment to any present or former employee or Independent Contractor of Target that is not listed on Section 5.19 of the Target Disclosure Schedule, and/or (ii) promised or otherwise provided any assurances (contingent or otherwise) to any present or former employee or Independent Contractor of Target that is not listed on Section 5.19 of the Target Disclosure Schedule any terms or conditions of employment with Acquiror following the Effective Time.

To the knowledge of Target, none of such persons has a direct or indirect ownership interest in any firm or corporation with which Target is affiliated or with which Target has a business relationship, except to the extent that employees, officers, or directors of Target and members of their immediate families own stock in publicly traded companies.

2.26 Third-Party Consents. Section 2.26 of the Target Disclosure Schedule lists all agreements, leases, licenses and contracts (with a specific reference to those agreements, leases, licenses or contracts containing “change of control,” “potential change of control,” or similar provisions) that require a novation or consent, as the case may be, in connection with the Merger so that Acquiror or the Surviving Corporation shall be made a party in place of Target or as an assignee (“Contracts Requiring Consent”).

2.27 Material Third Party Consents. Section 2.27 of the Target Disclosure Schedule sets forth every Contract Requiring Consent which, if no novation occurs to make Acquiror or the Surviving Corporation a party thereto or if no consent to assignment is obtained, could reasonably be expected to have a Material Adverse Effect on Acquiror’s or the Surviving Corporation’s ability to operate the business in the same manner as the business was operated by Target prior to the Effective Time.

2.28 Minute Books. The minute books of Target made available to Acquiror contain a complete and accurate summary in all material respects of all resolutions adopted and all other material actions taken at all meetings of directors and stockholders and all actions by written consent since the time of incorporation of Target through the date of this Agreement.

Since the Target Balance Sheet Date, Target has continued to replenish inventories in a normal and customary manner consistent with past practices. Target has not received written or oral notice that it will experience in the foreseeable future any difficulty in obtaining, in the desired quantity and quality and at a reasonable price and upon reasonable terms and conditions, the raw materials, supplies or component products required for the manufacture, assembly or production of its products. The values at which inventories are carried reflect the inventory valuation policy of Target, which is consistent with its past practice and in accordance with GAAP. Due provision has been made on the books of Target in the ordinary course of business consistent with past practices to provide for all slow-moving, obsolete, or unusable inventories to their estimated useful or scrap values and such inventory reserves are adequate to provide for such slow-moving, excess, obsolete or unusable inventory and inventory shrinkage. Except for the Designated Distributors, no customer or distributor has any right of return, price protection rights or stock rotation rights under any circumstances.

Target has conducted its export transactions in accordance with applicable provisions of United States export control laws and regulations, including but not limited to the Export Administration Act and implementing Export Administration Regulations, except for failures to comply with such laws or regulations which would not, individually or in the aggregate, reasonably be expected to have or constitute a Target Material Adverse Effect.

own its properties and to carry on its business as now being conducted and as proposed to be conducted and is duly qualified to do business and is in good standing in each jurisdiction in which the failure to be so qualified and in good standing would have an Acquiror Material Adverse Effect.

3.3 Authority. Acquiror and Merger Sub have all requisite corporate power and authority to enter into this Agreement and to consummate the transactions contemplated hereby. 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 Acquiror and Merger Sub. This Agreement has been duly executed and delivered by Acquiror and Merger Sub and constitutes the valid and binding obligations of Acquiror and Merger Sub enforceable against Acquiror and Merger Sub in accordance with its terms. The execution and delivery of this Agreement do not, and the consummation of the transactions contemplated hereby will not, conflict with, or result in any violation of, or default under (with or without notice or lapse of time, or both), or give rise to a right of termination, cancellation or acceleration of any obligation or loss of a benefit under (a) any provision of the Certificate of Incorporation or Bylaws of Acquiror or Merger Sub, as amended, or (b) any material mortgage, indenture, lease, contract or other agreement or instrument, permit, concession, franchise, license, judgment, order, decree, statute, law, ordinance, rule or regulation applicable to Acquiror or its properties or assets. No consent, approval, order or authorization of, or registration, declaration or filing with, any Governmental Entity, is required by or, to the knowledge of Acquiror, with respect to Acquiror or Merger Sub in connection with the execution and delivery of this Agreement by Acquiror and Merger Sub or the consummation by Acquiror and Merger Sub of the Merger and the other transactions contemplated hereby, except for (i) the filing of the Certificate of Merger with the Secretary of State of the State of Delaware; (ii) the filing of a Form 8-K under the Exchange Act; (iii) any filings as may be required under applicable state securities laws and the securities laws of any foreign country; (iv) such filings as may be required under HSR; (v) the Permit or the Registration Statement (as each is defined in Section 5.1), as applicable, and any filings with the SEC under the Securities Act and the Exchange Act, including, if applicable, pursuant to rules relating to (if any) the Registration Statement and Rules 135, 165 and 425 promulgated under the Securities Act; and (vi) such other consents, authorizations, filings, approvals and registrations which, if not obtained or made, would not prevent, materially alter or delay any of the transactions contemplated by this Agreement.

3.4 SEC Documents. Acquiror has timely filed all forms, reports and documents required to be filed by it with the SEC since January 1, 2002. As of their respective filing dates, each statement, report, effective registration statement (with the prospectus in the form filed pursuant to Rule 424(b) of the Securities Act), definitive proxy statement, and other filing filed with the SEC by Acquiror since and including the date of the Form 10-K most recently filed by Acquiror prior to the date hereof (collectively, the “Acquiror SEC Documents”) complied in all material respects with the applicable requirements of the Exchange Act and the Securities Act, and none of the Acquiror SEC Documents contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances in which they were made, not misleading in any material respect, except to the extent corrected by a subsequently filed Acquiror SEC Document.

3.5 Financial Statements. The financial statements of Acquiror, including the notes thereto, included in the Acquiror SEC Documents (the “Acquiror Financial Statements”) complied as to form in all material respects with applicable accounting requirements and with the published rules and regulations of the SEC with respect thereto as of their respective dates, and were prepared in accordance with GAAP applied on a basis consistent throughout the periods indicated and consistent with each other (except as may be indicated in the notes thereto or, in the case of unaudited statements included in Acquiror’s Quarterly Reports on Form 10-Q, as permitted by Form 10-Q under the Exchange Act). The Acquiror Financial Statements fairly present in all material respects the consolidated financial condition and operating results of Acquiror and its subsidiaries at the dates and during the periods indicated therein (subject, in the case of unaudited statements, to normal, recurring year-end audit adjustments).

3.6 Tax-Free Reorganization Matters. To Acquiror’s knowledge, neither Acquiror nor any of its affiliates has taken or agreed to take any action, nor does Acquiror have knowledge of any fact or circumstance, that would prevent the Merger from qualifying as a reorganization within the meaning of Section 368(a) of the Code.

(c) Nothing contained in this Section 4.3 shall prohibit Target from taking and disclosing to its stockholders a position contemplated by Rule 14e-2(a) promulgated under the Exchange Act or from making any required disclosure to Target’s stockholders if, in the good faith judgment of a majority of the disinterested directors of Target’s Board of Directors, upon advice of Target’s outside legal counsel, the failure so to disclose would constitute a breach of the Target Board’s fiduciary duties under Delaware Law.

(d) “Superior Proposal” means an unsolicited bona fide Takeover Proposal made by a third party that a majority of the disinterested (as to such Superior Proposal) directors of the Board of Directors of Target determines in good faith has the good faith intent to proceed with negotiations, and financial and other capabilities to consummate such Takeover Proposal, and intends to consummate the Takeover Proposal, taking into account, among other things, the legal, financial, regulatory and other aspects of such Takeover Proposal and the offeror, (i) on terms that a majority of the disinterested directors of Target’s Board determines in its good faith judgment to represent superior value for the stockholders of Target than the Merger (based on the written opinion, with only customary qualifications, of an independent financial advisor as to such proposal’s financial superiority), and (ii) that is substantially certain to be completed, taking into account all financial, regulatory, legal and other aspects of such Takeover Proposal and the offeror, on the terms existing at the time of termination of this Agreement.

(e) Target and Acquiror agree that irreparable damage would occur in the event that the provisions of this Section 4.3 were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed by the parties hereto that Acquiror shall be entitled to seek an injunction or injunctions or other equitable relief to prevent breaches of this Section 4.3 and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which the parties may be entitled at law or in equity.

Target shall ensure that the Target Stockholders Action is called, noticed, convened, held and otherwise conducted, and that all proxies and written consents solicited by Target in connection with the Target Stockholders Action are solicited, in compliance with Delaware Law, the Target Certificate of Incorporation and Bylaws, any applicable federal or state securities laws and all other applicable legal requirements.

Acquiror shall provide such assistance as Target may reasonably request in connection with its efforts to obtain such consents. The parties hereto will consult and cooperate with one another, and consider in good faith the views of one another, in connection with any analyses, appearances, presentations, memoranda, briefs, arguments, opinions and proposals made or submitted by or on behalf of any party hereto in connection with proceedings under or relating to HSR or any other federal or state antitrust or fair trade law.

In connection therewith, if any administrative or judicial action or proceeding is instituted (or threatened to be instituted) challenging any transaction contemplated by this Agreement as in violation of any Antitrust Law, each of Acquiror and Target shall cooperate and use all commercially reasonable efforts vigorously to contest and resist any such action or proceeding and to have vacated, lifted, reversed, or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent (each an “Order”), that is in effect and that prohibits, prevents, or restricts consummation of the Merger or any such other transactions, unless by mutual agreement Acquiror and Target decide that litigation is not in their respective best interests. Notwithstanding the provisions of the immediately preceding sentence, it is expressly understood and agreed that neither party shall have any obligation to litigate or contest any administrative or judicial action or proceeding or any Order beyond the earlier of (i) 150 days after the date of this Agreement or (ii) the date of a ruling preliminarily enjoining the Merger issued by a court of competent jurisdiction.

55 5.7 Notification of Certain Matters. Each party shall give prompt notice to the other party (either Acquiror or Target, as appropriate) of: (a) the occurrence or non-occurrence of any event, the occurrence or non-occurrence of which is likely to cause any representation or warranty of such party contained in this Agreement to be untrue or inaccurate in any material respect at or prior to the Effective Time, and (b) any failure of such party to comply with or satisfy, in any material respect, any covenant, condition or agreement to be complied with or satisfied by it hereunder; provided, however, that the delivery of any notice pursuant to this Section 5.7 shall not limit or otherwise affect any remedies available to the party receiving such notice. No disclosure pursuant to this Section 5.7, however, shall be deemed to amend or supplement the Target Disclosure Schedules or prevent or cure any misrepresentations, breach of warranty or breach of covenant.

5.8 Legal Requirements. Subject to Sections 5.6(b) and (c), each of Acquiror and Target will take all reasonable actions necessary to comply promptly with all legal requirements which may be imposed on them with respect to the consummation of the transactions contemplated by this Agreement and will promptly cooperate with and furnish information to any party hereto necessary in connection with any such requirements imposed upon such other party in connection with the consummation of the transactions contemplated by this Agreement and will take all reasonable actions necessary to obtain (and will cooperate with the other parties hereto in obtaining) any consent, approval, order or authorization of, or any registration, declaration or filing with, any Governmental Entity or other person, required to be obtained or made in connection with the taking of any action contemplated by this Agreement.

5.9 Tax-Free Reorganization. Neither Target, Acquiror nor Merger Sub will, either before or after consummation of the Merger, take any action which, to the knowledge of such party, would cause the Merger to fail to constitute a “reorganization” within the meaning of Code Section 368.

Acquiror shall take such steps as may be necessary to comply with the securities and blue sky laws of all jurisdictions which are applicable to the issuance of the Acquiror Common Stock in connection with the Merger.

Target shall use commercially reasonable efforts to cause the delivery to Acquiror at or prior to the Closing of a true, correct and complete copy of each election statement under Section 83(b) of the Code, if any, filed by each person who acquired unvested shares of Target Capital Stock or other property subject to substantial risk of forfeiture, together with evidence of timely filing of such election statement with the appropriate Internal Revenue Service Center (which evidence may, in the absence of an available file stamped copy or certified proof of mailing, consist of an affidavit signed by the acquiror of such unvested shares or property).

5.12 Target Warrants and Target Options.

In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full title to all properties, assets, rights, approvals, immunities and franchises, the proper officers and directors of each party to this Agreement shall take all such necessary action.

5.17 Expenses. Whether or not the Merger is consummated, all costs and expenses incurred in connection with or precedent to the Letter Agreement, this Agreement, the Merger and the transactions contemplated hereby and thereby shall be paid by the party incurring such expense; provided, however, that if the Merger is consummated, Acquiror shall bear the out-of-pocket expenses (including fees and expenses of one law firm, financial advisors, investment bankers and accountants) incurred by Target in connection with the Merger (collectively, the “Target Expenses”) up to the amount of the Covered Expenses. Any Target Expenses in excess of the Covered Expenses (collectively, the “Excess Target Expenses”) which have not been reimbursed to Target prior to the Effective Time by Target’s stockholders or included in the Expense Adjustment Amount used to determine the Base Consideration Exchange Ratio hereunder are collectively referred to as “Indemnifiable Target Expenses” and shall constitute “Damages” for purposes of claims against the Escrow Fund pursuant to Article VIII. The amount of Target Expenses and Excess Target Expenses as of the Closing Date shall be set forth on Section 5.17 to the Target Disclosure Schedule (the “Statement of Expenses”), which

57

Statement of Expenses shall be delivered by Target to Acquiror at the Closing. In preparing such Statement of Expenses, Target shall use its good faith best efforts to include all Target Expenses then known or reasonably estimable, and to include a statement, certified by a Target officer, that, to the best of Target’s knowledge, such Statement of Expenses includes all of the Target Expenses paid or payable at any time prior to, at or following the Effective Time, it being the parties expressed intent that to the maximum extent possible all the Excess Target Expenses be deducted from the Base Consideration Merger Shares and that there be no Indemnifiable Target Expenses. A draft of the Statement of Expenses shall be provided by Target to Acquiror not later than three (3) business days prior to the Closing Date. Without limiting the generality or effect of the provisions of Section 5.3, Target shall provide to Acquiror, promptly after Acquiror’s request, copies of the documents or instruments evidencing the amounts set forth on any draft Statement of Expenses or final Statement of Expenses.

Within 10 days after the end of each calendar month prior to the Closing Date, Target shall deliver to Acquiror unaudited financial statements (balance sheet, statement of operations and statement of cash flows) as at, and for the year-to-date period ended, on the last day of each such calendar month (the “Subsequent Target Financial Statements”). The Subsequent Target Financial Statements shall comply as to form in all material respects with applicable accounting requirements as of their respective dates, and shall be prepared in accordance with GAAP (except that they shall not have notes thereto and shall be subject to normal year-end audit adjustments which will not in the aggregate be material). The Subsequent Target Financial Statements shall fairly present in all material respects the financial condition and operating results of Target as of the dates, and during the periods indicated therein (subject, in the case of unaudited financial statements, to normal year-end audit adjustments). There shall be no significant deficiencies or material weaknesses in Target’s internal controls over financial reporting from the date hereof until Closing. Target shall use commercially reasonable efforts to obtain confirmation of inventory levels at the Designated Distributors as of the date of the September 30, 2003 Subsequent Target Financial Statements.

5.21 Delivery of Share Certificates.

5.22 Section 280G Matters.

(a) Target shall use commercially reasonable efforts to obtain and deliver to Acquiror, prior to the initiation of the requisite stockholder approval procedure under Section 5.22(b), a Section 280G Excess Parachute Payment Waiver, in substantially the form attached hereto as Exhibit G from each person who Target reasonably believes is, with respect to Target and/or any ERISA Affiliate, a “disqualified individual” (within the meaning of Section 280G of the Code and the regulations promulgated thereunder), as determined immediately prior to the initiation of the requisite stockholder approval procedure under Section 5.22(b), and who might otherwise have, receive or have the right or entitlement to receive an excess parachute payment under Section 280G of the Code, including any that will or may result from (i) the accelerated vesting of such person’s Target Options or unvested Target Capital Stock in connection with the Merger and/or the termination of employment or service with Target or with Acquiror following the Merger, (ii) any severance payments or other benefits or payments in connection with the Merger and/or the termination of employment or service with Target or with Acquiror following the Merger, and/or (iii) the receipt of any Target Options or Target Capital Stock within the 12-month period ending on the date on which the Effective Time occurs, pursuant to which each such person shall agree to waive, to the extent necessary to avoid an excess parachute payment under Section 280G of the Code, any and all right or entitlement to the accelerated vesting, payments, benefits, options and stock referred to in clauses (i), (ii) and (iii) unless the requisite stockholder approval of such accelerated vesting, payments, benefits, options and stock is obtained pursuant to Section 5.22(b).

(b) Target shall use commercially reasonable efforts to obtain, prior to the Closing, the approval by such number of stockholders of Target as is required by the terms of Section 280G(b)(5)(B) so as to render the parachute payment provisions of Sections 280G and 4999 of the Code inapplicable to any and all payments and/or benefits provided pursuant to agreements, contracts or arrangements related to the persons identified in Section 5.22(a) that, in the absence of such stockholder approval, might otherwise constitute, separately or in the aggregate, parachute payments under Section 280G of the Code. Such stockholder approval shall be obtained in a manner which satisfies all applicable requirements of such Section 280G(b)(5)(B) of the Code and the applicable Treasury Regulations thereunder.

(c) Target shall use its commercially reasonable efforts to obtain and deliver to Acquiror, at or prior to the Closing, written acknowledgement, in form and substance reasonably satisfactory to Acquiror, from each person to whom shares of Target Capital Stock have been transferred by a disqualified individual described in Section 5.22(a), that such person’s right to retain the such Target Capital Stock or receive any accelerated vesting or other benefits with respect to such stock shall be subject to stockholder approval (in accordance with Section 5.22(b)) pursuant to the waiver executed by the disqualified individual as required under Section 5.22(a).

5.23 Employee Benefits Matters. For a period beginning on the Closing Date and ending no earlier than December 31, 2003, Acquiror shall provide, or cause to be provided, to employees of the Target who continue employment with Acquiror or any of its subsidiaries (“Continuing Employees”) benefits that are, in the aggregate, substantially similar to or more favorable than the benefits provided to each of the Continuing Employees immediately prior to the Closing Date. During such period, Acquiror shall, to the extent allowed by law, (i) cause Continuing Employees to be credited with service with the Target for purposes of eligibility and vesting under any employee benefit plan or program (other than any cash bonus plan and any stock option or other equity incentive plans that Acquiror has in effect or may implement from time to time) established or maintained by Acquiror for the benefit of the Continuing Employees, (ii) cause its health and welfare plans to waive any pre-existing condition exclusions (to the extent such exclusion was waived under applicable health and welfare plans offered to the Continuing Employees by the Target) in respect of Continuing Employees (and their beneficiaries and dependants), and (iii) grant full credit to Continuing Employees (and their beneficiaries and dependants) for contributions, deductibles, co-payments and other attributes of participation in the Target’s health and welfare plans prior to Closing; provided, however, that if such insurance is not readily available on commercially reasonable terms, Acquiror shall be required to obtain only such insurance as is readily available on reasonable terms. Nothing in this Section 5.23 shall be construed to entitle any Continuing Employee to continue his or her employment with Acquiror or any of its subsidiaries or to entitle any Continuing Employee to receive any benefits following termination of such employment.

5.24 Director and Officer Indemnification. From and after the Effective Time, Acquiror will, and will cause the Surviving Corporation to, indemnify and hold harmless the present and former officers and directors of Target in respect of their status as an officer or director or in respect of acts or omissions by them occurring on or prior to the Effective Time in their capacity as an officer or director of Target to the extent provided under, in each case as in effect as of the date of this Agreement, (i) written agreements with such individuals, copies of which have been provided to Acquiror, and (ii) the Target’s Certificate of Incorporation and Bylaws; provided that such indemnification shall be subject to any limitation imposed from time to time under applicable law and shall not cover any Damages (as defined in Article VIII) incurred or paid by a Former Target Stockholder. Prior to the Effective Time, Target shall purchase the “Run-Off Coverage” for its director and officers under Target’s current insurance policy and such Run-Off Coverage shall be in full force and effect; provided that the premium shall not exceed $24,000, and any amount in excess thereof shall be subject to reasonable prior approval by Acquiror and shall constitute Target Expenses under Section 5.17. Such directors and officers shall be third-party beneficiaries of this Section 5.24.

5.25 SVB Pay-off. Prior to Closing, Target shall repay all debt owed to Silicon Valley Bank and shall deliver to Acquiror, in each case in a form reasonably acceptable to Acquiror, (i) Silicon Valley Bank’s agreement that all such indebtedness has been repaid, all of Silicon Valley Bank’s security interests have been released and that Target has no further obligations to Silicon Valley Bank, (ii) a completed UCC-3 termination statement releasing all liens against assets of Target, and (iii) evidence that all appropriate action has been taken in the U.S. Patent and Trademark Office with respect to the release of such security interests.

5.26 Acquiror Conduct of Business During Target Revenue Period. Acquiror covenants that it will not act in bad faith to take any action, or omit to take any action, which has as its purpose to materially and adversely affect or limit or prevent achievement of the Target Product Revenues goals set forth in Section 1.6.

(c) by Acquiror, if (i) Target shall breach any representation, warranty, obligation or agreement hereunder in any material respect (except for such representations and warranties that are qualified by their terms to materiality, which representations and warranties as so qualified shall be true in all respects), which breach would cause the condition set forth in Section 6.3(a) not to be satisfied, and such breach shall not have been cured within fifteen (15) business days of receipt by Target of written notice of such breach (provided, however, that the right to terminate this Agreement by Acquiror under this Section 7.1(c)(i) shall not be available to Acquiror where Acquiror is at that time in breach of this Agreement); (ii) the Board of Directors of Target shall have withdrawn or modified its recommendation of this Agreement or the Merger in a manner adverse to Acquiror or recommended, endorsed, accepted or agreed to a Takeover Proposal or shall have resolved to do any of the foregoing; (iii) Target, any subsidiary or any Representatives shall have failed to comply with Section 4.3; or (iv) for any reason Target fails to call and hold the Target Stockholders Action within 30 days after the date the Permit is issued or the Registration Statement becomes effective;

7.2 Effect of Termination. In the event of termination of this Agreement as provided in Section 7.1, this Agreement shall forthwith become void and there shall be no liability or obligation on the part of Acquiror or Target or their respective officers, directors, stockholders or affiliates, except to the extent that such termination results from the breach by a party hereto of any of its representations, warranties or covenants set forth in this Agreement; provided, however, that the provisions of Section 5.4 (Confidentiality), Section 5.5 (Public Disclosure), Section 5.17 (Expenses) (except to the extent modified by Section 7.3), Section 7.3 (Expenses and Termination Fees), this Section 7.2 and Article IX shall remain in full force and effect and survive any termination of this Agreement.

(d) As used herein, a “Trigger Event” shall occur if any “person” (as that term is defined in Section 13(d) of the Exchange Act and the regulations promulgated thereunder) acquires securities representing 20% (or solely with respect to the application of Section 7.3(c), 30%) or more, or commences a tender or exchange offer following the successful consummation of which the offeror and its affiliate would beneficially own securities representing 20% (or solely with respect to the application of Section 7.3(c), 30%) or more, of the voting power of Target; provided that a Trigger Event shall not be deemed to occur with respect to bona fide equity or debt financings of the Company in which only existing stockholders (or their affiliated funds or partners) of Target as of the date of the termination of this Agreement (“Existing Stockholders”) participate; provided further that any investment in Target by any person who is not an Existing Stockholder of Target during the six-month period specified in Section 7.3(c)(2) shall preclude the use by Target of the exception provided in the foregoing proviso.

(e) For purposes of this Agreement, “Takeover Proposal” means any offer or proposal for, or any indication of interest in, a merger or other business combination involving Target or any of its subsidiaries or the acquisition of 50% or more of the outstanding Target Capital Stock, or a significant portion of the assets of, Target or any of its subsidiaries, other than the transactions contemplated by this Agreement.

7.4 Amendment. The boards of directors of the parties hereto may cause this Agreement to be amended at any time by execution of an instrument in writing signed on behalf of each of the parties hereto; provided, however, that an amendment made subsequent to adoption of this Agreement by the stockholders of Target shall not (i) alter or change the amount or kind of consideration to be received on conversion of Target Capital Stock, (ii) alter or change any term of the Certificate of Incorporation of the Surviving Corporation to be effected by the Merger, or (iii) alter or change any of the terms and conditions of this Agreement if such alteration or change would materially adversely affect the holders of Target Capital Stock.

ARTICLE VIII

ESCROW AND INDEMNIFICATION

8.1 Survival of Representations, Warranties and Covenants. The representations and warranties of Target set forth in this Agreement and in any certificate, schedule, instrument or other document delivered by Target pursuant to this Agreement shall survive the Effective Time until April 2, 2005 (the “Survival Date”) (provided, however, that if an Officer’s Certificate (as defined herein) shall have been submitted pursuant to Section 8.6 with respect to any such representation or warranty on or prior to the Survival Date, the representation or warranty shall survive until, but only for purposes of, the resolution of the matter covered by such Officer’s Certificate), and shall in no way be affected by any investigation of the subject matter thereof made by or on behalf of Acquiror. The representations and warranties of Acquiror shall not survive the Effective Time. The covenants and agreements of the parties contained in this Agreement shall survive until the later of the Survival Date or the expiration of the time period for performance thereof as specified herein. Without limiting the generality of the foregoing, the agreements set forth in this Agreement shall terminate at the Effective Time, except that the agreements set forth in Article I; Sections 5.1(d) (Information Supplied – Permit), 5.1(f) (Information Supplied – Registration Statement), 5.4 (Confidentiality), 5.5 (Public Disclosure), 5.9 (Tax-Free Reorganization), 5.11 (Stock Options), 5.16 (Additional Agreements), 5.17 (Expenses), 5.24 (Director and Officer Indemnification), 5.26 (Acquiror Conduct of Business During the Target Revenue Period), 7.2 (Effect of Termination), 7.3 (Expenses and Termination Fees), and 7.4 (Amendment); Article VIII; and Article IX shall survive the Effective Time and the Closing for the time period necessary to fulfill the obligations therein.

8.2 Indemnification.

(a) Subject to the provisions set forth in this Article VIII and provided that the Merger is consummated, the Former Target Stockholders, severally (in accordance with the respective Escrow Allocations (defined below)) and not jointly, will indemnify and hold harmless Acquiror, its officers, directors, agents, employees and subsidiaries (including the Surviving Corporation), and each person, if any, who controls or may control Acquiror within the meaning of the Securities Act (hereinafter referred to individually as an “Indemnified Person” and collectively as “Indemnified Persons”) from and against any and all losses, costs, payments (including in satisfaction of appraisal rights), damages, liabilities, accruals and expenses, including reasonable legal fees (collectively,

“Damages”), resulting from or in connection with any assessment, tax, assertion of liability, claim, demand, suit, litigation, proceeding, dispute, arbitration, governmental audit, inquiry, criminal prosecution, investigation, charge, complaint or similar action (collectively, “Claims”) arising out of:

(i) any misrepresentation or breach of or default in performance of any of the representations, warranties, covenants and agreements given or made by Target in this Agreement, the Target Disclosure Schedule, any exhibit or schedule to this Agreement and in any certificate, schedule, instrument or other document delivered by Target pursuant to this Agreement (Claims with respect to any of the foregoing not involving Intellectual Property Rights being “General Claims”, and Claims with respect to any of the foregoing involving Intellectual Property Rights being “IP Claims”);

(ii) any negotiations, settlements and/or proceedings related to a demand for appraisal rights by a Dissenting Stockholder; provided, however, that with respect to this clause, Damages shall only be deemed incurred to the extent (A) the aggregate amount of Damages incurred by Target or the Surviving Corporation with respect to such negotiations, settlements and/or proceedings to all Dissenting Stockholders exceeds (B) the product of (x) the number of shares of Acquiror Common Stock that would have been received by such Dissenting Stockholders had they exchanged their shares of Target Capital Stock multiplied by (y) the Acquiror Stock Price (the “Appraisal Damages”);

(iii) any Indemnifiable Target Expenses; or

(iv) any Final Additional Consideration Share Deficit.

“Damages” as used herein is not limited to matters asserted by third parties, but includes Damages incurred or sustained by Acquiror in the absence of claims by a third party. Damages shall be without duplication (e.g., if Acquiror is reimbursed for Damages, the Surviving Corporation or other Indemnified Parties would not be reimbursed for the same Damages as suffered by Acquiror and could only be indemnified for additional incremental Damages such as additional expenses or damages). Only Acquiror (or a person or entity designated in writing by Acquiror) may bring a claim pursuant to this Section 8.2 to recover for Damages that are economic losses of the Surviving Corporation. In the event of fraud or intentional misrepresentation, each of the Former Target Stockholders, jointly and severally, shall be liable to indemnify the Indemnified Persons, up to the total value of the shares of Acquiror Common Stock received by such stockholder hereunder, valued at the Acquiror Stock Price and without regard to the Damages Threshold (as defined herein). In determining the amount of any Damage resulting from any misrepresentation, breach or default, any materiality standard contained in the applicable representation, warranty or covenant shall be disregarded. Acquiror and Target each acknowledge that such Damages, if any, would relate to unresolved contingencies existing at the Effective Time, which if resolved at the Effective Time would have led to a reduction in the total number of shares of Acquiror Common Stock that Acquiror would have agreed to issue in connection with the Merger.

(b) Nothing in this Agreement shall limit (i) the liability of Target for any breach of any representation, warranty or covenant if the Closing does not occur, (ii) the liability of any Former Target Stockholder, option holder, warrant holder or other

70

security holder in connection with any breach by such Former Target Stockholder, option holder, warrant holder or other security holder of any agreement executed by such person in connection with this Agreement or the transactions contemplated hereby, including a Stockholder Agreement, or (iii) Acquiror’s rights to specific performance or injunctive relief pursuant to Sections 4.3 and 9.9.

8.3 Escrow Fund. As security for the indemnity provided for in Section 8.2 hereof, the Escrow Shares shall be registered in the name of, and be deposited with, JPMorgan Chase Bank, as escrow agent (the “Escrow Agent”), or its nominee, such deposit to constitute the Escrow Fund to be governed by the terms set forth herein and in the Escrow Agreement. If the Merger is consummated, recovery from the Escrow Fund shall be the exclusive remedy for Acquiror’s Damages, absent fraud or intentional misrepresentation. The Escrow Fund, including the portions thereof designated as General Escrow Shares and Secondary Escrow Shares, shall be allocated among the Former Target Stockholders on a pro-rata basis, based on the percentage of the Merger Shares deposited into the Escrow Fund, including the portions thereof designated as General Escrow Shares and Secondary Escrow Shares, attributable to such Former Target Stockholder (the “Escrow Allocation”) (excluding for purposes of this calculation any Dissenting Shares until such shares lose their status as such pursuant to Section 1.8(g)). Upon compliance with the terms hereof and subject to the provisions of this Article VIII, Acquiror and the Surviving Corporation shall be entitled to obtain indemnity from the Escrow Fund for Damages covered by the indemnity provided for in Section 8.2.

8.4 Damages Threshold. The Indemnified Persons shall not receive any shares from the Escrow Fund with respect to item (i) of the first sentence of Section 8.2(a) unless and until Damages which exceed $300,000 in the aggregate (the “Damages Threshold”) have been determined to have been incurred by Indemnified Persons pursuant to this Article VIII, at which point the Former Target Stockholders shall be liable for all Damages over and above the $300,000 Damages Threshold. Notwithstanding the foregoing, in no event shall any Appraisal Damages, Indemnifiable Target Expenses or any Final Additional Consideration Share Deficit be subject to the Damages Threshold, nor shall such Appraisal Damages, Indemnifiable Target Expenses and Final Additional Consideration Share Deficit be included in any determination of whether Damages exceed the Damages Threshold.

8.5 Escrow Period. The Escrow Fund shall terminate on the later of (a) the Distribution Date with respect to the Final Additional Consideration Shares or, if there shall be no such distribution of Final Additional Consideration Shares, then the 30^th day following the filing of Acquiror’s Quarterly Report on Form 10-Q for the quarter in which the Target Revenue Period ends or (b) in the event of any dispute under Section 1.6(c)(iii), on the 30^th day following the resolution of such dispute (the “Escrow Termination Date”); provided, however, that a portion of the Escrow Shares which is necessary to satisfy any unsatisfied claims specified in any Officer’s Certificate (as defined below) delivered to the Escrow Agent prior to the Escrow Termination Date with respect to facts and circumstances existing prior to the Escrow Termination Date shall remain in the Escrow Fund until such claims have been resolved.

71

8.6 Claims upon Escrow Fund.

(a) Claim Procedure. Claims under Section 8.2 against the Escrow Fund with respect to Target’s representations and warranties shall be made on or prior to the tenth business day after the Survival Date to the extent the claim arose on or prior to the Survival Date. Any other claims against the Escrow Fund shall be made on or prior to the Escrow Termination Date. Subject to Section 8.6(b) below, upon receipt by the Escrow Agent on or before the Escrow Termination Date of a certificate signed by the chief financial or chief executive officer of Acquiror (an “Officer’s Certificate”):

(i) stating that an Indemnified Person has incurred, paid or properly accrued, or reasonably and in good faith anticipates that it may incur, pay or properly accrue in connection with any Claims made or initiated prior to the Escrow Termination Date, Damages and the amount of such Damages (which, in the case of Damages not yet incurred, paid or properly accrued, may be the maximum amount reasonably and in good faith anticipated to be incurred, paid or properly accrued);

(ii) specifying in reasonable detail the individual items of Damages included in the amount so stated, the date each such item was incurred, paid or properly accrued and the specific nature of the Claim to which such Damages are related; and

(iii) specifying whether and to what extent the Damages are to be deducted from the General Escrow Shares or the Secondary Escrow Shares; then

the Escrow Agent shall, subject to the provisions of Section 8.7 and Section 8.8 of this Agreement, deliver to Acquiror (on behalf of itself or any other Indemnified Person) out of the Escrow Fund, including the portions thereof designated as General Escrow Shares and Secondary Escrow Shares, as promptly as practicable, Acquiror Common Stock or other property held in the Escrow Fund, including the portions thereof designated as General Escrow Shares and Secondary Escrow Shares, having a value equal to such Damages; provided, however, that, to the extent that such Damages have not then been incurred, paid or properly accrued by such Indemnified Person, Acquiror (on behalf of itself or any other Indemnified Person) shall not be so entitled to receive, and the Escrow Agent shall not deliver, shares or other property held in the Escrow Fund in respect thereof unless and until such Damages are actually incurred, paid or properly accrued by such Indemnified Person. Subject to the provisions of Section 8.7 and Section 8.8, all shares of Acquiror Common Stock subject to such claims shall remain in the Escrow Fund until the earliest to occur of (A) Damages actually are incurred or paid, (B) Acquiror determines in its reasonable good faith judgment that no Damages will be required to be incurred or paid, or (C) with respect to claims which Acquiror has accrued or disclosed, the earlier of (1) such time as the claims are no longer accrued or disclosed or (2) the expiration of the applicable statute of limitations, in which event such shares shall be distributed in accordance with Section 8.10.

(b) Priority and Order of Claims. General Claims shall be made and paid from and against, and shall be limited to, the portion of the Escrow Fund comprised of the General Escrow Shares, except in the case of fraud or intentional misrepresentation for which Acquiror shall have access to the Escrow Fund in addition to any other rights hereunder. IP Claims first shall be made and paid from and against the portion of the Escrow Fund comprised of the Secondary Escrow Shares but shall not be limited thereto. After exhaustion of the Secondary Escrow Shares (or to the extent that an unresolved IP Claim would exceed the Secondary Escrow

72

Shares), IP Claims thereafter may be made against the General Escrow Shares to the full extent any such shares remain in the Escrow Fund.

(c) Valuation of Escrow Shares. For the purpose of compensating Acquiror (on behalf of itself or any other Indemnified Person) for Damages pursuant to this Agreement, the Acquiror Common Stock in the Escrow Fund shall be valued at the Acquiror Stock Price (as adjusted to appropriately reflect any stock split, reverse stock split, stock dividend, reorganization, reclassification, combination, recapitalization or other like change with respect to Acquiror Common Stock occurring after the Effective Time). Any compensation or indemnification received by Acquiror under this Article VIII shall be deemed to be, and shall be treated as, an adjustment to the Merger consideration.

8.7 Objections to Claims. At the time of delivery of any Officer’s Certificate to the Escrow Agent, a duplicate copy of such Officer’s Certificate shall be delivered by Acquiror to the Stockholder Representative and, for a period of 30 days after such delivery to the Escrow Agent, the Escrow Agent shall make no delivery of Acquiror Common Stock or other property pursuant to Section 8.6 hereof unless the Escrow Agent shall have received written authorization from the Stockholder Representative to make such delivery. After the expiration of such 30-day period, the Escrow Agent shall make delivery of the Acquiror Common Stock or other property in the Escrow Fund in accordance with Section 8.6 hereof and as set forth in a certificate provided by Acquiror, provided that no such distribution or delivery may be made if the Stockholder Representative shall object in a written statement to the claim made in the Officer’s Certificate, and such statement shall have been delivered to the Escrow Agent and to Acquiror prior to the expiration of such 30-day period.

8.8 Resolution of Conflicts; Arbitration.

(a) In case the Stockholder Representative shall so object in writing to any claim or claims by Acquiror made in any Officer’s Certificate, the Stockholder Representative and Acquiror shall attempt in good faith for 30 days to agree upon the rights of the respective parties with respect to each of such claims in dispute. If the Stockholder Representative and Acquiror should agree on a resolution, a memorandum setting forth such agreement shall be prepared and signed by both parties and shall be furnished to the Escrow Agent. The Escrow Agent shall be entitled to rely on any such memorandum and shall distribute the Acquiror Common Stock or other property from the Escrow Fund in accordance with the terms thereof.

(b) If no such agreement can be reached after good faith negotiation, either Acquiror or the Stockholder Representative may, by written notice to the other, demand arbitration of the matter unless the amount of the Damages is at issue in pending litigation with a third party, in which event arbitration shall not be commenced until such amount is ascertained or both Acquiror and the Stockholder Representative agree to arbitration, and, in such event, the matter shall be settled by arbitration conducted by a single arbitrator. Acquiror and the Stockholder Representative shall jointly select an arbitrator. If Acquiror or the Stockholder Representative fail to agree upon an arbitrator within thirty (30) days, an arbitrator shall be selected for them by the American Arbitration Association (“AAA”). The decision of the arbitrator so selected as to the validity and amount of any claim in such Officer’s Certificate shall be binding and conclusive upon the parties to this Agreement, and, notwithstanding anything in

Section 8.6, the Escrow Agent shall be entitled to act in accordance with such decision and make or withhold payments or distributions out of the Escrow Fund in accordance with such decision.

(c) Judgment upon any award rendered by the arbitrator may be entered in any court having jurisdiction. Any such arbitration shall be held in Austin, Texas under the commercial rules then in effect of the AAA. For purposes of this Section 8.8, in any arbitration hereunder in which any claim or the amount thereof stated in the Officer’s Certificate is at issue, Acquiror shall be deemed to be the “Non-Prevailing Party” unless the arbitrator awards Acquiror more than 50% of the amount in dispute; otherwise, the Former Target Stockholders shall be deemed to be the Non-Prevailing Party. The Non-Prevailing Party to an arbitration shall pay its own expenses, the fees of the arbitrator, the administrative fee of the AAA, and the expenses, including legal fees and costs reasonably incurred by the other party to the arbitration.

8.9 Stockholder Representative.

(a) In the event the Merger is approved by Target’s stockholders, effective upon such vote, and without any further action of any Target stockholder, Walter Thirion shall be constituted and appointed as Stockholder Representative for and on behalf of each Former Target Stockholder (except such stockholders, if any, as shall have perfected their dissenter’s rights under Delaware Law), to give and receive notices and communications, to authorize delivery to Acquiror of shares of Acquiror Common Stock or other property from the Escrow Fund in satisfaction of claims by Acquiror (on behalf of itself 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 Stockholder Representative for the accomplishment of the foregoing, in each case without having to seek or obtain the consent of any person under any circumstance. The Stockholder Representative may resign at any time, and such agency may be changed by the holders of a majority-in-interest of the Escrow Fund from time to time, in each case upon not less than 10 days’ prior written notice to Acquiror and Escrow Agent (and Escrow Agent shall be provided promptly with a facsimile copy of the signature of any such successor stockholders agent). Any vacancy in the position of the Stockholder Representative may be filled by approval of the holders of a majority-in-interest of the Escrow Fund. No bond shall be required of the Stockholder Representative, and the Stockholder Representative shall not receive compensation for his or her services. Notice or communications to or from the Stockholder Representative pursuant to Section 9.1 of this Agreement shall constitute notice to or from each of the Former Target Stockholders.

(b) A decision, act, consent or instruction of the Stockholder Representative shall constitute a decision of all Former Target Stockholders for whom shares of Acquiror Common Stock otherwise issuable to them are deposited in the Escrow Fund and shall be final, binding and conclusive upon each such Former Target Stockholder, and the Escrow Agent and Acquiror may rely upon any decision, act, consent or instruction of the Stockholder Representative as being the decision, act, consent or instruction of each and every such Former Target Stockholder. The Escrow Agent and Acquiror are hereby relieved from any liability to any person for any acts done by them in accordance with such decision, act, consent or instruction of the Stockholder Representative.

(c) The Stockholder Representative has only the duties expressly stated in this Agreement and the Escrow Agreement, and shall have no other duty, express or implied. The Stockholder Representative is not, nor shall be deemed, a fiduciary of the Former Target Stockholders in any capacity or for any purpose. The Stockholder Representative shall have no responsibility or liability for any representation, warranty or covenant of the Target, the Surviving Company, the Acquiror or the Merger Sub except, if applicable, solely in his capacity as a Former Target Stockholder. The Stockholder Representative shall not be liable to any Former Target Stockholder for any act done or omitted hereunder as representative of Former Target Stockholders while acting in good faith even though such act or omission constitutes, or may constitute, negligence or gross negligence on the part of such Stockholder Representative. The Stockholder Representative shall, in no case or event, be liable to any Former Target Stockholder for punitive, incidental or consequential damages. Without limiting the generality of the foregoing, the Stockholder Representative shall not be liable for forgeries or false impersonations by other parties. The Stockholder Representative may engage attorneys, accountants and other professionals and experts. The Stockholder Representative shall not receive any compensation for his services in such capacity; provided, however, that the Stockholder Representative shall be entitled to reimbursement from the Former Target Stockholders for his reasonable out-of-pocket expenses, including reasonable attorney’s fees, incurred in performing his duties and functions up to a maximum aggregate amount of $50,000, and, to the extent that shares of Acquiror Common Stock remain in the Escrow Fund, shall be entitled to reimbursement for such out-of-pocket expenses from the Escrow Fund in the form of the number of shares of Acquiror Common Stock equal to (i) such actual out-of-pocket expenses not to exceed $50,000 in the aggregate, divided by (y) the Acquiror Stock Price. The Stockholder Representative may in good faith rely conclusively on information, reports, statements, opinions, including financial statements, about the Target, the Surviving Corporation or another person, that were prepared or presented by (i) one or more officers or employees of the Target or Surviving Corporation, or (ii) legal counsel, public accountants, investment bankers or other persons as to matters the Stockholder Representative believes in good faith are within the person’s knowledge, professional or expert competence. Any action taken by a Stockholder Representative based on such reliance shall be deemed conclusively to have been taken in good faith and in full satisfaction of such Stockholder Representative’s duties. The Former Target Stockholders on whose behalf the Escrow Amount was contributed to the Escrow Fund shall indemnify the Stockholder Representative and hold the Stockholder Representative harmless from and against any loss, liability or expense incurred without bad faith on the part of the Stockholder Representative and arising out of or in connection with the acceptance or administration of the Stockholder Representative’s duties hereunder, including the Stockholder Representative’s obligations to the Escrow Agent hereunder and the reasonable fees and expenses of any legal counsel retained by the Stockholder Representative.

(d) The Stockholder Representative shall have reasonable access to information about Target, Surviving Corporation and Acquiror and the reasonable assistance of Target’s, Surviving Corporation’s or Acquiror’s officers and employees for purposes of performing his duties and exercising his rights hereunder, provided that the Stockholder Representative shall treat confidentially and not disclose any nonpublic information from or about Target, Surviving Corporation or Acquiror to anyone (except on a need-to-know basis to individuals who agree to treat such information confidentially).

8.10 Distribution Upon Termination of Escrow Period. Promptly following the Escrow Termination Date, the Escrow Agent shall deliver to the Former Target Stockholders all of the shares in the Escrow Fund in excess of any amount of such shares reasonably necessary to satisfy any unsatisfied or disputed claims for Damages specified in any Officer’s Certificate delivered to the Escrow Agent on or before the Escrow Termination Date. As soon as all such claims have been resolved, the Escrow Agent shall deliver to the Former Target Stockholders all shares remaining in the Escrow Fund and not required to satisfy such claims. Deliveries of shares to the Former Target Stockholders pursuant to this Section shall be made in proportion to the Escrow Allocation.

8.11 Third-Party Claims. In the event Acquiror becomes aware of a third-party claim that Acquiror believes may result in a demand against the Escrow Fund, Acquiror shall promptly notify the Stockholder Representative of such claim, and the Stockholder Representative shall be entitled, at the Stockholder Representative’s expense, to participate in any defense of such claim. Acquiror shall have the right in its sole discretion to settle any such claim; provided, however, that Acquiror may not effect the settlement of any such claim without the consent of the Stockholder Representative, which consent shall not be unreasonably withheld, conditioned or delayed. In the event that the Stockholder Representative has consented to any such settlement, the Stockholder Representative shall have no power or authority to object under Section 8.6 or Section 8.7 or any other provision of this Article VIII to the amount of any claim by Acquiror against the Escrow Fund for indemnity with respect to such settlement.

8.12 Allocation of Liability and Remedies. Except as provided in the final paragraph of Section 8.2(a), the liability of any Former Target Stockholder for damages under this Article VIII shall be several and not joint, and any assertion of Damages against any Former Target Stockholder may only be made pro rata based on the percentage of Escrow Shares attributable to each Former Target Stockholder, as set forth in the Escrow Allocation. Except as expressly set forth in this Article VIII, no Former Target Stockholder, option holder, warrant holder, director, officer, employee or agent of Target shall have any personal liability to Acquiror or the Surviving Corporation after the Closing in connection with the Merger; provided, however, that nothing herein limits any potential remedies and liabilities of Acquiror or the Surviving Corporation, arising under applicable state and federal laws against any security holder, director, officer, employee or agent of Target with respect to that person’s commission of fraud or intentional misrepresentation.

9.2 Interpretation. When a reference is made in this Agreement to a Section, Article, Schedule or Exhibit, such reference shall be to a Section, Article, Schedule or Exhibit to this Agreement unless otherwise indicated. The words “include,” “includes” and “including” when used herein shall be deemed in each case to be followed by the words “without limitation.” The phrases “the date of this Agreement”, “the date hereof”, and terms of similar import, unless the context otherwise requires, shall be deemed to refer to the date this Agreement is executed and delivered by the parties hereto. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

77 9.3 Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties, it being understood that all parties need not sign the same counterpart.

9.4 Entire Agreement; Third Party Beneficiaries; Nonassignability. This Agreement and the documents and instruments and other agreements specifically referred to herein or delivered pursuant hereto, including the Exhibits, the Target Disclosure Schedule and the Acquiror Disclosure Schedule (a) constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof, including without limitation, the Letter Agreement, except for Section 2.1 (Confidentiality) and Section 2.11 (Authority) of such Letter Agreement, which shall continue in full force and effect, and shall survive any termination of this Agreement or the Closing, in accordance with its terms, (b) except as provided in Section 5.24 above, are not intended to confer upon any other person any rights or remedies hereunder, and (c) shall not be assigned by operation of law or otherwise except as otherwise specifically provided herein; provided, however, that Merger Sub may assign its rights and obligations under this Agreement to any other wholly-owned subsidiary of Acquiror without the prior consent of Target. Except as otherwise provided in this Section 9.4, no right, interest or obligation with respect to any Additional Consideration Shares under this Agreement may be assigned by any Former Target Stockholder. Notwithstanding anything to the contrary contained herein, this Section 9.4 shall not be deemed to restrict a transfer to an Eligible Assignee; however, any such rights or interests or obligations hereunder shall not be further assignable by such Eligible Assignees except to the extent otherwise allowable under this Section 9.4 or expressly provided in Section 1.6(c)(iv) above. No right, interest, or obligation with respect to any Additional Consideration Shares under this Agreement will be evidenced by negotiable certificates of any kind nor be readily marketable. For purposes of this Agreement, the term “Eligible Assignee” shall mean an assignee or transferee of the rights of a Former Target Stockholder hereunder but only if such assignee or transferee is (i) a beneficial owner of equity interests of such Former Target Stockholder as of the date hereof, (ii) an executor, administrator or guardian of the estate of such Former Target Stockholder or beneficial owner, (iii) an inter vivos trust for the benefit of such Former Target Stockholder or beneficial owner or a member of such Former Target Stockholder’s or beneficial owner’s immediate family, (iv) a legatee or heir of such Former Target Stockholder or beneficial owner under the will of such Former Target Stockholder or beneficial owner or pursuant to the laws of descent and distribution, (v) a person who acquires such rights by operation of law (including pursuant to a property settlement agreement, plan or arrangement approved or ordered by any court) or (vi) the Acquiror or any subsidiary of the Acquiror. Subject to the foregoing provisions, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and permitted assigns.

9.5 Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement will continue in full force and

effect and the application of such provision to other persons or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto. The parties further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

9.6 Remedies Cumulative. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy.

9.7 Governing Law; Jurisdiction. This Agreement shall be governed by and construed in accordance with the laws of the State of Texas without regard to applicable principles of conflicts of law. EACH PARTY HERETO CONSENTS AND SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF TEXAS IN AND FOR THE COUNTY OF TRAVIS AND THE COURTS OF THE UNITED STATES LOCATED IN THE WESTERN DISTRICT OF TEXAS FOR THE ADJUDICATION OF ANY ACTION, SUIT, OR PROCEEDING ARISING OUT OF OR OTHERWISE RELATING TO THIS AGREEMENT. Each party agrees not to assert, by way of motion, as a defense or otherwise, in any such action, suit or proceeding, any claim it may now or hereafter have that it is not subject personally to the jurisdiction of such court, that the action, suit, or proceeding is brought in an inconvenient forum, that the venue of the action, suit, or proceeding is improper, or that this Agreement or the subject matter hereof may not be enforced in or by such court. Each party further irrevocably submits to the jurisdiction of such court in any such action, suit, or proceeding and irrevocably agrees to be bound by any final judgment rendered thereby in connection with this Agreement from which no appeal has been taken or is available. Any and all service of process and any other notice in any such action, suit or proceeding shall be effective against any party if given personally or by registered or certified mail, postage prepaid and return receipt requested, or by personal service on such party. Nothing contained herein shall be deemed to affect the right of any party to serve process in any manner permitted by law or to commence legal proceedings or otherwise proceed against any other party in any other jurisdiction.

9.8 Rules of Construction. The parties hereto agree that they have been represented by counsel during the negotiation, preparation and execution of this Agreement and, therefore, waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

9.9 Enforcement. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached.
