2.9 Company Options; Warrants. At the Effective Time:

(a) Each outstanding and unexercised Company Option under the Company Option Plan, by virtue of the Merger and without any action on the part of the holder thereof, shall be assumed by Parent in accordance with its terms (as in effect as of the date of this Agreement) of such Company Option Plan under which such Company Option was issued and the stock option agreement by which such Company Option is evidenced. All rights with respect to Company Common Stock under Company Options shall thereupon be converted into rights with respect to Parent Common Stock. Accordingly, from and after the Effective Time, (i) each Company Option assumed by Parent may be exercised solely for shares of Parent Common Stock; (ii) the number of shares of Parent Common Stock subject to each such assumed Company Option shall be equal to the number of shares of Company Common Stock that were subject to such Company Option immediately prior to the Effective Time multiplied by the Common Stock Exchange Ratio, rounded down to the nearest whole number of shares of Parent Common Stock; and (iii) the per share exercise price for the Parent Common Stock issuable upon exercise of each such assumed Company Option shall be determined by dividing the exercise price per share of Company Common Stock subject to such Company Option, as in effect immediately prior to the Effective Time, by the Common Stock Exchange Ratio, and rounding the resulting exercise price up to the nearest whole cent, and all restrictions on the exercise of each such assumed Company Option shall continue in full force and effect, and the term, exercisability, vesting schedule and other provisions of such Company Option shall otherwise remain unchanged; provided, however, that each such assumed Company Option shall, in accordance with its terms, be subject to further adjustment as set forth in Section 2.10 and such number of shares of Parent Common Stock and the per share exercise price of each Company Option shall be further adjusted by adding the Milestone Shares as set forth in Section 2.14 and adjusting the exercise price of such Company Option. The Company and Parent shall take all action that may be necessary (under the Company Stock Plan and otherwise) to effectuate the provisions of this Section 2.9(a).

(b) Each outstanding and unexercised Company Warrant, by virtue of the Merger and without any action on the part of the holder thereof, shall be assumed by Parent in accordance with the warrant certificate by which such Company Warrant is evidenced. All rights with respect to Company Common Stock under Company Warrants shall thereupon be converted into rights with respect to Parent Common Stock. Accordingly, from and after the Effective Time, (i) each Company Warrant assumed by Parent may be exercised solely for shares of Parent Common Stock; (ii) the number of shares of Parent Common Stock subject to each such assumed Company Warrant shall be equal to the number of shares of Company Common Stock that were subject to such Company Warrant immediately prior to the Effective Time multiplied by the Common Stock Exchange Ratio, rounded down to the nearest whole number of shares of Parent Common Stock; and (iii) the per share exercise price for the Parent Common Stock issuable upon exercise of each such assumed Company Warrant shall be determined by dividing the exercise price per share of Company Common Stock subject to such Company Warrant, as in effect immediately prior to the Effective Time, by the Common Stock Exchange Ratio, and rounding the resulting exercise price up to the nearest whole cent, and all restrictions on the exercise of each such assumed Company Warrant shall continue in full force and effect, and the term, exercisability, vesting schedule and other provisions of such Company Warrant shall otherwise remain unchanged; provided, however, that each such assumed Company

Warrant shall, in accordance with its terms, be subject to further adjustment as set forth in Section 2.10 and such number of shares of Parent Common Stock and the per share exercise of each Company Warrant shall be further adjusted by adding the Milestone Shares as set forth in Section 2.14 and adjusting the exercise price of such Company Warrant. The Company and Parent shall take all action that may be necessary to effectuate the provisions of this Section 2.9(b).

2.10 Adjustments to Exchange Ratios. Notwithstanding any other provision of this Agreement, the Common Stock Exchange Ratio, Series A Exchange Ratio and Series B Exchange Ratio shall be adjusted, at any time and from time to time, to fully reflect the effect of any stock split, reverse split, stock dividend (including, without limitation, any dividend or distribution of securities convertible into Parent Common Stock or Company Capital Stock, as the case may be), reorganization, recapitalization or other like change with respect to Parent Common Stock or, if permitted by the terms of Section 5.1, Company Capital Stock (including any lapsing of Company Options or repurchase of Company Capital Stock), as the case may be, occurring during the Interim Period (as defined in Section 5.1) or following the Effective Time during the time periods provided on Exhibit D for achievement of the Milestones.

2.11 Dissenters Rights.

(a) Notwithstanding any other provision in this Agreement to the contrary, shares of Company Capital Stock outstanding immediately prior to the Effective Time that are held by any “Person” (as defined in Section 13(a)(9) of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”)), who (i) has not voted such shares in favor of adoption of this Agreement and the Merger; and (ii) properly demands appraisal of such shares pursuant to, and in compliance with, Section 262 of the DGCL (“Section 262”) (such shares, the “Dissenting Shares”) shall not be converted into the right to receive Merger Shares, but rather the holders of Dissenting Shares shall be entitled only to payment of the fair market value of such Dissenting Shares in accordance with Section 262; provided, however, that if any such holder fails to perfect or otherwise waives, withdraws or loses the right to seek appraisal under Section 262, then such Dissenting Shares shall be deemed to have been converted as of the Effective Time into, and to have become exchangeable solely for the right to receive the Closing Shares as provided in Section 2.7 and shall have an interest in the Milestone Shares as provided in Section 2.14.

(b) The Company shall give prompt notice to Parent of any demands received by the Company for appraisal of any shares of Company Capital Stock and Parent shall have the right to participate in and direct all negotiations and proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, without the prior written consent of Parent, which consent shall not be unreasonably withheld, conditioned or delayed, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing.

2.12 Escrow of Merger Shares. The Company Stockholders immediately prior to the Effective Time shall be entitled to receive eighty percent (80%) of the Closing Shares into which the shares of Company Capital Stock held by each of them were converted pursuant to Section 2.7, rounded to the nearest whole number, upon delivery of the certificates representing such shares of Company Capital Stock to Parent (the “Initial Shares”). The remaining twenty percent (20%) of the Closing Shares into which the shares of Company Capital Stock held by

each of them were converted pursuant to Section 2.7 shall be deposited into the Escrow Fund. In addition, twenty percent (20%) of any Milestone Shares subsequently issued to the Company Stockholders shall be deposited into the Escrow Fund.

2.13 No Fractional Shares. No certificate or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender of Company Certificates for exchange, and such fractional share interests will not entitle the owner thereof to vote or to any other rights of a stockholder of Parent. Notwithstanding any other provision of this Agreement, each holder of shares of Company Capital Stock who would otherwise be entitled to receive a fraction of a share of Parent Common Stock (after taking into account all Company Certificates delivered by such holder) shall receive from Parent, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a share of Parent Common Stock multiplied by the Common Stock Exchange Ratio, the Series A Exchange Ratio or the Series B Exchange Ratio, as applicable.

2.14 Milestone Shares. On each Applicable Distribution Date, by virtue of the Merger, if First, Second or Third Milestone Shares are earned based on achievement of the milestones set forth on the attached Exhibit D:

(a) For achievement of the First Milestone, each share of Company Common Stock, Series A Preferred Stock and Series B Preferred Stock that was outstanding immediately prior to the Effective Time and each Company Option and Company Warrant that was outstanding immediately prior to the Effective Time and subsequently exercised (to the extent so exercised) will be entitled to receive the number of First Milestone Shares as calculated by the conversion ratios set forth on Exhibit D attached hereto, each respective ratio subject to adjustment as set forth in Section 2.10 or in the event the Aggregate Merger Consideration is reduced as set forth in such definition of Aggregate Merger Consideration.

2.15 Exchange Procedures.

(a) Exchange Agent. Prior to the Effective Time, Parent shall designate a bank or trust company reasonably acceptable to the Company to act as Exchange Agent in the Merger.

(b) Parent to Provide Common Stock. When and as needed, Parent shall make available to the Exchange Agent for exchange through such procedures as Parent may reasonably adopt, sufficient shares of Parent Common Stock to be exchanged pursuant to Section 2.7 of the Agreement; provided, however, that the Escrow Shares shall be kept by the Escrow Agent in accordance with Section 2.12 and distributed in accordance with the terms of the Escrow Agreement.

(c) Exchange of Shares. Promptly after the Effective Time, the Surviving Corporation shall cause to be mailed to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Company Common Stock or Company Preferred Stock whose shares were converted into the right to receive shares of Parent Common Stock pursuant to Section 2.7, a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Company Certificates shall pass, only upon delivery of the Company Certificates to the Exchange Agent and shall be in such form and have such other provisions as Parent may reasonably specify) and instructions for use in effecting the surrender of the Company Certificates in exchange for certificates representing Initial Shares of Parent Common Stock. Upon surrender of a Company Certificate for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the holder of such Company Certificate shall be entitled to receive in exchange therefor a certificate representing the number of whole Initial Shares of Parent Common Stock and payment in lieu of fractional shares which such holder has the right to receive pursuant to Section 2.13, and the Certificate so surrendered shall forthwith be canceled. Any right of the Company Stockholder to receive Escrow Shares shall be determined in accordance with the provisions of the Escrow Agreement. Until so surrendered or the right to appraisal under Section 262 has been perfected, each outstanding Company Certificate that, prior to the Effective Time, represented shares of Company Common Stock or Company Preferred Stock shall be deemed from and after the Effective Time, for all corporate purposes, to evidence the right to receive the number of full shares of Parent Common Stock into which the holder of

such shares of Company Common Stock or Company Preferred Stock is entitled and the right to receive an amount in cash in lieu of the issuance of any fractional shares in accordance with Section 2.13. Any portion of the shares of Parent Common Stock deposited with the Exchange Agent which remains undistributed to the Company Stockholders for six (6) months after the Effective Time shall be delivered to Parent, upon demand, and any holders of shares of Company Common Stock or Company Preferred Stock who have not theretofore complied with this Section 2.15(c) shall thereafter look only to Parent and only as general creditors thereof for payment of their claim for Parent Common Stock, any cash in lieu of fractional shares of Parent Common Stock and any dividends or distributions with respect to Parent Common Stock to which such holders may be then entitled.

(d) Distributions With Respect to Unexchanged Shares. No dividends or other distributions declared or made after the Effective Time with respect to Parent Common Stock with a record date after the Effective Time will be paid to the holder of any unsurrendered shares of Company Common Stock or Company Preferred Stock with respect to the shares of Parent Common Stock represented thereby until the holder of record of such Company Certificate shall surrender such Company Certificate. Subject to applicable law, following surrender of any such Company Certificate, there shall be paid to the record holder a Certificate representing the whole number of Initial Shares of Parent Common Stock to be issued in exchange therefor, without interest, at the time of such surrender, any cash in lieu of fraction shares of Parent Common Stock and any dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole number of shares of Parent Common Stock.

(e) Transfers of Ownership. If any certificate for shares of Parent Common Stock is to be issued in a name other than that in which the Company Certificate surrendered in exchange therefor is registered, it shall be a condition of the issuance thereof that the Company Certificate so surrendered shall be properly endorsed and otherwise in proper form for transfer and that the Company Stockholder requesting such exchange shall have paid to Parent, or any agent designated by it, any transfer or other taxes required by reason of the issuance of a certificate for shares of Parent Common Stock in any name other than that of the registered holder of the certificate surrendered, or established to the reasonable satisfaction of Parent or any agent designated by it that such tax has been paid or is otherwise not payable.

2.16 No Liability. Notwithstanding any other provision of this Agreement, none of the Exchange Agent, Parent or the Surviving Corporation shall be liable to a Company Stockholder for any shares of Parent Common Stock or any amount of cash properly paid to a public official pursuant to any applicable abandoned property, escheat or similar law.

2.17 Taking of Necessary Action; Further Action. If, at any time and from time to time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest in the Surviving Corporation full right, title and possession of all assets, properties, rights, privileges, powers and franchises of the Company, the officers and directors of the Surviving Corporation shall be and are fully authorized and directed, in the name of and on behalf of the Company to take, or cause to be taken, all such lawful and necessary action as is not inconsistent with this Agreement.

ARTICLE VIII

INDEMNIFICATION

8.1 Indemnification. Subject to the limitations set forth in Section 8.4 below, the Company Stockholders, jointly and severally, shall indemnify and hold harmless the Surviving Corporation, Parent, any officers, directors, employees or agents or Affiliates thereof and their successors and assigns (a “Compensated Person”), from and against any and all debts, obligations and other liabilities (whether absolute, accrued, contingent, fixed or otherwise, or whether known or unknown, or due or to become due or otherwise), monetary damages, fines, fees, penalties, interest obligations, Taxes, deficiencies, losses and expenses (including, without

limitation, amounts paid in settlement, interest, court costs, costs of investigators, fees and expenses of attorneys, accountants, financial advisors and other experts, and other expenses of litigation) (collectively, “Damages”), incurred or suffered by the Compensated Person resulting from or relating to:

(a) the breach of any representation or warranty of the Company contained in this Agreement or the failure to perform any covenant or agreement of the Company contained in this Agreement or in any certificate, exhibit or schedule hereto; or

(b) any Damages arising or resulting from the assertion of liability by any third party or parties based on the breach of any representation or warranty of the Company or the failure to perform any covenant or agreement of the Company contained in this Agreement or in any certificate, exhibit or schedule hereto or from the assertion of liability by any third party regarding the transactions contemplated by this Agreement and all certificates, exhibits and schedules hereto or any third party claim based on the actions of the Company prior to the date of this Agreement (“Third Party Claims”).

8.2 Method of Asserting Claims.

(a) Notice of Claim. A Compensated Person may from time to time make demand of the Company Stockholders for claims of indemnification under this Article VIII by serving upon the Indemnification Representative and the Escrow Agent a written notice demanding payment of an indemnification claim arising under Section 8.1 of this Agreement (a “Demand”). Such Demand shall describe in reasonable detail the nature of the claim, an estimate of the amount of Damages attributable to such claim and the basis of the Compensated Person’s request for indemnification under this Agreement. No delay on the part of the Compensated Person in notifying the Indemnification Representative shall relieve the Company Stockholders from any obligation hereunder.

(b) Response to a Demand. The Indemnification Representative may reply to the Demand made under Section 8.2(a) hereof by written notice given to the Compensated Person and the Escrow Agent, which notice shall state whether the Indemnification Representative agrees or disagrees that the claim asserted by the Compensated Person is a valid claim under this Agreement and agrees or disagrees with respect to the amount of the Damages in such Demand. If, within thirty (30) days after receipt of the Demand (the “Indemnity Notice Period”), the Indemnification Representative does not give to the Compensated Person and the Escrow Agent a notice which asserts that a dispute exists with respect to such Demand specifying the nature and amount of such dispute or if the Indemnification Representative gives notice that the Demand is uncontested, then the Escrow Agent shall release from the Escrow Fund and deliver to the Compensated Person such number of Escrow Shares as shall equal the amount of the Damages claimed, and the Escrow Fund shall be reduced to the extent thereof, with each Company Stockholder’s percentage of the Escrow Fund reduced in proportion to his, her or its ownership interest in the Escrow Shares (his, her or its “Pro Rata Share”). If the notice from the Indemnification Representative admits that a portion of the Demand is a valid claim under Section 8.1 of this Agreement and a portion of the Demand is disputed, the Escrow Agent shall disburse the number of Escrow Shares to the Compensated Person for the Damages which

are agreed upon (the “Undisputed Portion”) and the disputed portion of such Demand shall be resolved in accordance with Section 8.2(c).

(c) Disputed Claims. If the notice given by the Indemnification Representative as provided in Section 8.2(b) hereof disputes the claim or claims asserted in the Demand by the Compensated Person or the amount of Damages thereof within the Indemnity Notice Period (a “Disputed Claim”), then the Demand shall be treated as a Disputed Claim and the amount of such claim shall be held by the Escrow Agent as an undivided portion of the Escrow Fund. The Escrow Agent shall not disburse any shares from the Escrow Fund as to a Disputed Claim until the earlier to occur of: (i) the settlement of the Disputed Claim by the Indemnification Representative and the Compensated Person; and (ii) the final adjudication of the Company Stockholders’ liability to the Compensated Person by a court of law or arbitration panel.

(d) Third Party Claims

(i) Notice of Third Party Claims. A Compensated Person shall promptly give written notice to the Indemnification Representative and the Escrow Agent of any Third Party Claim that might give rise to any Damages for which indemnification may be sought from the Company Stockholders (a “Notice of Third Party Claim”), stating the nature and basis of such Third Party Claim, and the amount of Damages thereof to the extent known. Such Notice of Third Party Claim shall be accompanied by copies of all relevant documentation with respect to such Third Party Claim, including, without limitation, any summons, complaint or other pleading that may have been served, any written demand or any other document or instrument. Notwithstanding the foregoing, the failure to provide notice as aforesaid to the Indemnification Representative and Escrow Agent will not relieve the Company Stockholders from any liability which they may have to the Compensated Person under this Agreement or otherwise. No delay on the part of the Compensated Person in notifying the Indemnification Representative or Escrow Agent will relieve the Company Stockholders from any obligation hereunder.

(ii) Defense of Third Party Claims. The Company Stockholders may elect to defend any Third Party Claim with counsel of their own choosing, reasonably acceptable to Compensated Person, within thirty (30) days after receipt of the Notice of Claim by the Indemnification Representative (the “Election to Defend”), and shall act reasonably and in accordance with their good faith business judgment in handling such Third Party Claim, provided that no Third Party Claim may be settled without the consent of the Compensated Person and provided that the Company Stockholders defend such claim actively and diligently. If the Company Stockholders choose not to defend any Third Party Claim by failure to deliver the Election to Defend or by failure to meet the conditions specified above, the Compensated Person may defend against such Third Party Claim and consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim in any manner it may deem appropriate and seek indemnification pursuant to this Article VIII for Damages resulting from such Third Party Claim in accordance with Section 8.1 above. In addition, if the Company Stockholders have assumed defense of the Third Party Claim and if a potential or actual conflict of interest shall exist or if different defenses shall be available between the Company

Stockholders on one hand and the Compensated Person on the other, then the Compensated Person shall be entitled to retain separate legal counsel and submit the fees and expenses of such counsel as part of a Demand for Indemnification pursuant to Section 8.1. The Company Stockholders and the Compensated Person shall make available to each other and their counsel and accountants all books and records and information relating to any Third Party Claim, keep each other fully apprised as to the details and progress of all proceedings relating thereto and render to each other such assistance as may be reasonably required to ensure the proper and adequate defense of any Third Party Claim.

(e) Payment in Cash in Lieu of Escrow Shares. Notwithstanding the foregoing, any Company Stockholder who has deposited at least 1,000 Merger Shares in the Escrow Fund (an “Eligible Holder”) may elect to pay his, her or its Pro Rata Share of any indemnification amount for Damages in cash in lieu of Escrow Shares by payment of the Stipulated Value (as defined in Section 8.4(a) below) in cash per Escrow Share. The Indemnification Representative shall not be obligated to give more than twenty (20) calendar days’ notice to such Eligible Holders prior to any expected disbursement from the Escrow Fund for indemnification hereunder and, in any case, only to such Eligible Holder’s last known address as provided to the Indemnification Representative by the Company immediately prior to the Closing or by the Eligible Holder after Closing. Each Eligible Holder must respond within ten (10) calendar days of receiving such notice if the Eligible Holder elects to pay Damages in cash in lieu of Escrow Shares and must remit such cash payment within such ten (10) calendar day period in accordance with the instructions provided by the Indemnification Representative. The Indemnification Representative shall remit any payment of Damages in cash on behalf of the Company Stockholders to the Escrow Agent. Upon receipt of a cash payment in lieu of Escrow Shares, the Escrow Agent shall then release such number of Escrow Shares to the Company Stockholder who has paid in cash. In any response to a Demand, the Indemnification Representative shall instruct the Escrow Agent as to which Company Stockholders have elected to pay in cash and absent such instruction from the Indemnification Representative, the Escrow Agent shall be entitled to assume that all such Company Stockholders have elected to pay in Escrow Shares.

8.3 Survival. The representations, warranties, covenants and agreements of the Company and Parent set forth in this Agreement and in any certificate, exhibit or schedule hereto shall survive the Closing for a period of two (2) years and shall not be affected by any examination made for or on behalf of the Compensated Person or the knowledge of any of the Compensated Person’s officers, directors, stockholders, employees, agents or Affiliates; except that claims, if any, asserted in writing prior to such expiration and identified as a claim for indemnification shall survive until finally resolved and satisfied in full. If a claim for indemnification is made before expiration of such period, then (notwithstanding the expiration of such time period) the representation, warranty, covenant or agreement applicable to such claim shall survive until, but only for purposes of, the resolution of such claim.

8.4 Limitations. The obligations of the Company Stockholders to indemnify a Compensated Person shall be subject to the following limitations:

(a) The Escrow Shares shall be held in the Escrow Fund for a period of two (2) years, subject to extension if a claim is pending pursuant to the provisions of this Article

VIII. Each Escrow Share shall at all times be valued at $1.54 (subject to adjustment for any event set forth in Section 2.10, the “Stipulated Value”) for the purpose of determining the number of shares required to be forfeited for payment of Damages under this Agreement or for determining the dollar amount for payment of Damages in cash in lieu of Escrow Shares.

(b) A Compensated Person’s recourse for Damages shall be limited to the amount of the Escrow Fund. The maximum liability of each Company Stockholder shall be limited to the total number of Escrow Shares deposited by such Company Stockholder in the Escrow Fund, which shall include twenty percent (20%) of any and all Milestone Shares subsequently earned by a Company Stockholder.

(c) In the event a Demand has been satisfied in part but not in full and for which a Compensated Person is entitled to indemnification pursuant to this Article VIII, any Milestone Shares that are deposited into the Escrow Fund subsequent to such Demand and its satisfaction in part and not in whole will be included for purposes of calculating a Company Stockholder’s aggregate liability for satisfaction of any such prior Demand.

(d) No Demand may be made pursuant to this Article VIII unless and until the aggregate Damages exceed $50,000, at which point the Company Stockholders shall become liable for the aggregate amount of the Damages including the initial $50,000 of Damages.

Except with respect to claims based on fraud or willful misrepresentation, the rights of the Compensated Persons under this Article VIII shall be the exclusive remedy of the Compensated Persons with respect to claims resulting from or relating to any misrepresentation, breach of warranty or failure to perform any covenant or agreement of the Company contained in this Agreement or any Third Party Claim.

8.5 Indemnification Representative. From and after the Effective Time, TVM V Life Science Ventures GmbH & Co. shall serve as indemnification representative and shall act as agent for and on behalf of the Company Stockholders, or his or her successor (the “Indemnification Representative”) and shall be authorized to act on behalf of the Company Stockholders and to take any and all actions required or permitted to be taken by the Indemnification Representative under this Agreement with respect to any claims (including the settlement thereof) made by a Compensated Person for indemnification pursuant to this Article VIII and with respect to any actions to be taken by the Indemnification Representative pursuant to the terms of the Escrow Agreement, which shall include, without limitation, the exercise of the power to: (i) authorize the delivery of Escrow Shares to a Compensated Person in satisfaction of claims by a Compensated Person; (ii) agree to, negotiate, enter into settlements and compromises of, and comply with orders of courts with respect to any claims for indemnification; and (iii) take all actions necessary in the judgment of the Indemnification Representative for the accomplishment of the foregoing. In all matters relating to this Article VIII as described in the preceding sentence, the Indemnification Representative shall be the only party entitled to assert the rights of the Company Stockholders, and the Indemnification Representative shall perform all of the obligations of the Company Stockholders hereunder. Any Compensated Person shall be entitled to rely on all statements, representations and decisions of the Indemnification Representative. The Indemnification Representative is not entitled to amend this Agreement or take any actions relating to this Agreement prior to the Effective Time. Following the Effective

Time, the Indemnification Representative may amend this Agreement with the prior written consent of the holders of a majority-in-interest in the Merger Shares. The Indemnification Representative may resign upon not less than twenty (20) Business Days’ prior written notice to Parent and the Company Stockholders. The Company Stockholders by the vote of a majority-in-interest of the Merger Shares held by the Company Stockholders may remove the Indemnification Representative from time to time upon not less than twenty (20) Business Days’ prior written notice to Parent. Any vacancy in the position of the Indemnification Representative may be filled by the approval of the holders of a majority-in-interest in the Merger Shares held by the Company Stockholders. Any successor Indemnification Representative shall acknowledge in writing to Parent his or her acceptance of the appointment as Indemnification Representative.

(b) If Parent delays or suspends the Registration Statement or requires that the Company Stockholders cease sales of shares pursuant to Section 9.3(a), Parent shall, as promptly as practicable following the termination of the circumstance which entitled Parent to do so, take such actions as may be necessary to file or reinstate the effectiveness of the Registration Statement and/or give written notice to the Company Stockholders authorizing them to resume sales pursuant to the Registration Statement. If as a result of such suspension or delay the prospectus included in the Registration Statement has been amended to comply with the requirements of the Securities Act, Parent shall enclose such revised prospectus with notice to the Company Stockholders provided pursuant to this Section 9.3(b), and the Company Stockholders shall not offer or sell any shares pursuant to the Registration Statement other than by means of such revised prospectus.

9.4 Registration Procedures.

(a) In connection with the filing by Parent of the Registration Statement, Parent shall deliver to each Company Stockholder a copy of the prospectus, including a preliminary prospectus, as may be necessary to comply with the requirements of the Securities Act with respect to the registration and disposition of the Merger Shares.

(b) Parent shall register the Merger Shares covered by the Registration Statement, or qualify the Merger Shares for an exemption from registration, under the securities laws of each jurisdiction in the United States where such shares are to be offered or sold; provided, however, that Parent shall not be required in connection with this Section 9.4(b) to qualify as a foreign corporation or to execute a general consent to service of process in any jurisdiction.

(c) Parent shall prepare and file with the SEC amendments or supplements to such Registration Statement as may be necessary to comply with the provisions of the Securities Act, and if Parent has delivered preliminary or final prospectuses to the Company Stockholders and such prospectus is amended or supplemented to comply with the requirements of the Securities Act after delivery, Parent shall promptly notify the Company Stockholders and, if requested by Parent, the Company Stockholders shall immediately cease any offer or sale pursuant to the Registration Statement and return all prospectuses to Parent. Parent shall promptly provide the Company Stockholders with revised supplemented prospectuses and, following the receipt of such prospectuses, the Company Stockholders may resume the offer or sale of shares pursuant to the Registration Statement.

(d) Parent shall take all action necessary to cause such Merger Shares to be approved for listing on the Nasdaq National Market and/or on any securities exchange on which shares of Parent Common Stock are listed for exchange.

(e) Parent shall pay the expenses incurred by it in complying with its obligations under this Article IX, including all registration and filing fees, exchange listing fees, fees and expenses of counsel for Parent, and fees and expenses for accountants of Parent, but

excluding: (i) any brokerage fees, selling commissions or underwriting discounts incurred by the Company Stockholders in connection with sales pursuant to the Registration Statement; and (ii) any fees and expenses of counsel retained by any of the Company Stockholders.

9.5 Company Stockholder Requirements. Parent shall not be required to include any Merger Shares in the Registration Statement unless:

(a) The Company Stockholder owning such shares furnishes to Parent in writing such information regarding such Company Stockholder and the proposed sale of the Merger Shares by the Company Stockholder as Parent may reasonably request in connection with the Registration Statement or as required by the SEC;

(b) Such Company Stockholder shall have provided to Parent a written agreement:

(i) to indemnify Parent and each of its directors and officers against, and hold Parent and each of its directors and officers harmless from, any losses, claims, damages, expenses or liabilities (including reasonable attorneys fees) to which Parent or such directors and officers may become subject by reason of any statement or omission in the Registration Statement made in reliance upon, or in conformity with, a written statement by such Company Stockholder and furnished pursuant to this Section 9.5; and

(ii) to report to Parent sales made pursuant to the Registration Statement within twenty-four (24) hours thereof.

9.6 Parent Indemnification. Parent agrees to indemnify and hold harmless each Company Stockholder whose shares are included in the Registration Statement against any losses, claims, damages, expenses or liabilities to which such Company Stockholder may become subject by reason of any untrue statement of a material fact contained in the Registration Statement or any omission of a fact required to be stated therein in order to make such statements not misleading, except insofar as such losses, claims, damages, expenses or liabilities arise out of or are based upon information provided to Parent by or on behalf of any Company Stockholder for use in the Registration Statement. Parent shall have the right to assume the defense and settlement of any claim or suit for which Parent may be responsible for indemnification pursuant to this Section 9.6.

9.7 Assignment of Rights. A Company Stockholder may not assign or transfer any of its rights under this Article IX except in connection with the transfer of some or all of his, her or its Merger Shares; provided, however, each such transferee agrees in a written instrument delivered to Parent to be bound by the provisions of this Article IX.
