This AGREEMENT AND PLAN OF MERGER (this “Agreement”) is made and entered into as of December 4, 2006, by and among Kyphon Inc., a Delaware corporation (“Parent”), Neptune Acquisition Sub, Inc., a Delaware corporation and direct wholly-owned subsidiary of Parent (“Merger Sub”), and St. ▇▇▇▇▇▇▇ Medical Technologies, Inc., a Delaware corporation (the “Company”), and with respect to Article VII only, ▇▇▇▇▇▇ ▇. ▇▇▇▇▇, as Stockholders’ Representative.

RECITALS

A. The respective Boards of Directors of Parent, Merger Sub and the Company have deemed it advisable and in the best interests of their respective corporations and stockholders that Parent and the Company consummate the business combination and other transactions provided for herein in order to advance their respective long-term strategic business interests.

B. The respective Boards of Directors of Parent, Merger Sub and the Company have approved, in accordance with applicable provisions of the laws of the State of Delaware (“Delaware Law”), this Agreement and the transactions contemplated hereby, including the Merger (as defined in Section 1.1).

C. Promptly following the execution and delivery of this Agreement, stockholders of the Company representing the requisite number of shares of each class of the Company’s capital stock will, through an action by written consent (the “Stockholder Approval”), adopt this Agreement.

D. Parent, Merger Sub and the Company desire to make certain representations, warranties and agreements in connection with the Merger and also to prescribe certain conditions to the Merger.

NOW, THEREFORE, in consideration of the covenants, promises and representations set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

ARTICLE I.

THE MERGER

1.1 The Merger. At the Effective Time and subject to and upon the terms and conditions of this Agreement and the applicable provisions of Delaware Law, Merger Sub shall be merged with and into the Company (the “Merger”), the separate corporate existence of Merger Sub shall cease and the Company shall continue as the surviving corporation. The Company, as the surviving corporation after the Merger, is hereinafter sometimes referred to as the “Surviving Corporation.”

1.2 Effective Time; Closing. Subject to the provisions of this Agreement, the parties hereto shall cause the Merger to be consummated by filing a Certificate of Merger with the Secretary of State of the State of Delaware in accordance

with the relevant provisions of Delaware Law (the “Certificate of Merger”) (the time of such filing with the Secretary of State of the State of Delaware (or such later time as may be agreed in writing by the Company and Parent and specified in the Certificate of Merger) being the “Effective Time”) as soon as practicable on or after the Closing Date (as defined below). The closing of the Merger (the “Closing”) shall take place at the offices of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇, Professional Corporation, located at One Market, San Francisco, California, at a time and date to be specified by the parties, which shall be no later than the second business day after the satisfaction or waiver of the conditions set forth in Article VI (other than those that by their terms are to be satisfied or waived at the Closing), or at such other time, date and location as the parties hereto agree in writing. The date on which the Closing occurs is referred to herein as the “Closing Date.”

1.3 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in this Agreement and the applicable provisions of Delaware Law, including Section 259 of the General Corporation Law of the State of Delaware. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time all the property, rights, privileges, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

1.4 Certificate of Incorporation and Bylaws. At the Effective Time, the Certificate of Incorporation of the Surviving Corporation shall be amended and restated in its entirety to be identical to the Certificate of Incorporation of Merger Sub, until thereafter amended in accordance with Delaware Law and as provided in such Certificate of Incorporation; provided, however, that at the Effective Time, Article I of the Certificate of Incorporation of the Surviving Corporation shall be amended and restated in its entirety to read as follows: “The name of the corporation is “St. ▇▇▇▇▇▇▇ Medical Technologies, Inc.” At the Effective Time, the Bylaws of the Surviving Corporation shall be amended and restated in their entirety to be identical to the Bylaws of Merger Sub, until thereafter amended in accordance with Delaware Law and as provided in such Bylaws; provided, however, that at the Effective Time, if necessary, the Bylaws shall be amended so as to comply with Section 5.8(b).

1.5 Directors and Officers. The initial directors of the Surviving Corporation shall be the directors of Merger Sub immediately prior to the Effective Time, until their respective successors are duly elected or appointed and qualified. The initial officers of the Surviving Corporation shall be the officers of the Company immediately prior to the Effective Time, until their respective successors are duly appointed.

1.6 Effect on Capital Stock. Subject to the terms and conditions of this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the holders of any shares of capital stock of the Company, the following shall occur:

(a) Company Capital Stock. Each share of the Common Stock (“Company Common Stock”), Series A Preferred Stock (“Series A Preferred Stock”), Series B Preferred Stock (“Series B Preferred Stock”) and Series C Preferred Stock

-2-

(“Series C Preferred Stock”), par value $0.001 per share, of the Company issued and outstanding immediately prior to the Effective Time (collectively, “Company Capital Stock”), other than any shares of Company Capital Stock to be canceled pursuant to Section 1.6(b) and the Dissenting Shares (as defined in Section 1.6(c)(i)), will be canceled and extinguished and automatically converted into the right to receive the Per Share Consideration (as defined in Section 7.1) upon surrender of the certificate representing such share of Company Capital Stock and delivery of a duly completed letter of transmittal in the manner provided in Section 1.8 (or, in the case of a lost, stolen or destroyed certificate, upon delivery of an affidavit, and the giving of an indemnity undertaking if required) in the manner provided in Section 1.10, and any amounts payable with respect to such share pursuant to Section 1.7.

(b) Cancellation of Treasury and Parent Owned Stock. Each share of Company Capital Stock held by the Company or Parent or any direct or indirect wholly-owned Subsidiary (as defined in Section 2.1(a)) of the Company or of Parent immediately prior to the Effective Time shall be canceled and extinguished without any conversion thereof.

(i) Notwithstanding anything in this Agreement to the contrary, any shares of Company Capital Stock outstanding immediately prior to the Effective Time and held by a holder who has not voted in favor of the Merger or consented thereto in writing and who has exercised and perfected appraisal or dissenter’s rights for such shares in accordance with Section 262 of the Delaware General Corporation Laws (the “DGCL”) or Chapter 13 of the California Corporations Code and has not effectively withdrawn or lost such appraisal or dissenter’s rights (collectively, the “Dissenting Shares”) shall not be converted into or represent the right to consideration for Company Capital Stock set forth in Sections 1.6(a) and 1.7, and the holder or holders of such shares shall be entitled only to such rights as may be granted to such holder or holders in Chapter 13 of the California Corporations Code or Section 262 of the DGCL.

(ii) Notwithstanding the provisions of Section 1.6(c)(i), if any holder of Dissenting Shares shall effectively withdraw or lose (through failure to perfect or otherwise) such holder’s appraisal rights and dissenter’s rights under Chapter 13 of the California Corporations Code and Section 262 of the DGCL, then, as of the later of the Effective Time and the occurrence of such event, such holder’s shares shall automatically be converted into and represent only the right to receive the consideration for Company Capital Stock set forth in Sections 1.6(a) and 1.7, without interest, upon surrender of the certificate representing such shares.

(d) Stock Options. Each option to purchase Company Common Stock issued under the Company’s 1999 Stock Incentive Plan, as amended (the “Company Option Plan”), or otherwise listed in Section 2.2(b) of the Company Disclosure Letter, whether or not exercisable, whether or not vested, and whether or not performance-based, which is outstanding immediately prior to the Effective Time (each, a “Company Option”), shall not be assumed by the Surviving Corporation or Parent, but shall instead

-3-

be converted immediately prior to the Effective Time, but in any event after giving effect to the action set forth in Section 5.7(f)(i) into the right to receive payment of an amount in cash (in addition to any amounts payable pursuant to Section 1.7) equal to the excess, if any, of the product of the Per Share Consideration and the total number of shares of Company Common Stock deliverable upon exercise of such Company Option (regardless of whether or not any such Company Option is then “vested” or exercisable) (the “Option Shares”) over the aggregate exercise price of such Option Shares (the right to receive such cash payment for each Option Share, a “Cash Payment Right”). Each Cash Payment Right shall be vested as of the Effective Time to the extent the Company Option so converted in accordance with this Section 1.6(d) is vested as of the Effective Time (after taking into account the accelerated vesting set forth in Section 5.7(f)(i)). At the Closing, each vested Cash Payment Right shall be paid to the holder thereof, and each unvested Cash Payment Right shall be paid into escrow pursuant to the terms of a Management Escrow Agreement to be entered into as of the Closing Date, the form of which is attached hereto as Exhibit A (the “Management Escrow Agreement”).

(e) 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 one (1) validly issued fully, paid and nonassessable share of common stock of the Surviving Corporation.

(f) Closing Certificate. At the Closing, the Company shall deliver to Parent a certificate (the “Closing Certificate”) substantially in the form attached hereto as Exhibit B, signed by the Company’s Chief Executive Officer or Chief Financial Officer, certifying on behalf of the Company as to (i) the number of shares of Company Common Stock, Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock outstanding immediately prior to the Effective Time, (ii) the number of Option Shares outstanding immediately prior to the Effective Time, and (iii) the amount of Closing Expenses.

1.7 Additional Merger Consideration.

(a) Definitions. For purposes of this Agreement, the following terms shall have the following meanings:

“Change of Control” shall mean (i) a merger or consolidation of Parent into or with any of the Persons listed on Schedule 1.7(a) and/or any of their affiliates (the “Specified Persons”) in a transaction or series of related transactions that results in more than 50% of the voting securities of Parent or the surviving, resulting or parent entity in such transaction or series of related transactions that are outstanding immediately after the consummation thereof being held by Persons other than those Persons that (individually or collectively) held such voting securities of Parent immediately prior to the consummation thereof, (ii) a sale or other disposition of all or substantially all of the assets or voting securities of Parent to any Specified Person(s) or (iii) a sale or other disposition to any Person (other than an Affiliate of Parent) of the Company Business or the business comprised of the IPD Devices (whether by sale of securities or assets).

-4-

“Earnout Amount” shall mean either the First Earnout Amount and/or the Second Earnout Amount as applicable to the time period at issue.

“Earnout Revenue” shall mean either the First Earnout Revenue or the Second Earnout Revenue as applicable to the time period at issue.

“First Deferred Payment Date” shall mean (i) February 14, 2008, but only if the Stockholders’ Representative delivers written notice to Parent prior to January 31, 2008, stating that it will reserve any dispute of the First Earnout Amount until such time, if any, as it disputes the Second Earnout Amount pursuant to Section 1.7(c), otherwise (ii) ten (10) business days after the date of final resolution of the First Earnout Amount pursuant to Section 1.7(c), including resolution of any Disputed Items.

“First Earnout Amount” shall mean an amount equal to the product of (i) the First Earnout Revenue and (ii) two (2); provided, however, if the First Earnout Amount exceeds $200,000,000, the First Earnout Amount shall be deemed equal to $200,000,000.

“First Earnout Revenue” shall mean the Revenue during the six-month period commencing on July 1, 2007, and ending at the close of business on December 31, 2007.

“IPD Devices” shall mean the Company’s X STOP^® interspinous process decompression device as such product is marketed as of the date hereof, together with all modifications thereto.

“Per Share Earnout Amount” shall mean the Earnout Amount divided by the Outstanding Shares, rounded to four decimal places.

“Revenue” shall mean the gross customer invoiced amounts for sales of IPD Devices in the United States, less credits issued for actual returns of IPD Devices. In the event that an IPD Device is sold by either Parent, the Company or any of their respective Affiliates in the form of a kit or other similar assemblage of products containing one or more components other than an IPD Device, Earnout Revenue for such IPD Device will be calculated by multiplying the Earnout Revenue from such assemblage of products by the fraction A/(A+B) where A is the average selling price in the United States from the IPD Device if sold separately during the applicable period by such Person or an Affiliate, and B is the total average selling price in the United States from all other components in the assemblage of products that are not IPD Devices during the applicable period. If no average selling price of any other component is available for the United States, the Earnout Revenue from the IPD Device shall be calculated by the Earnout Revenue from such assemblage of products by the fraction A/C where A is the average selling price in the United States from the IPD Device if sold separately during the applicable period by such Person or an Affiliate, and C is the total selling price of such kit or other assemblage of products.

“Second Deferred Payment Date” shall mean ten (10) business days after the date of final resolution of the Second Earnout Amount pursuant to Section 1.7(c), including resolution of any Disputed Items.

-5-

“Second Earnout Amount” shall mean an amount equal to the product of (i) the Second Earnout Revenue and (ii) two (2); provided, however, if the sum of the First Earnout Amount and the Second Earnout Amount exceeds $200,000,000, the Second Earnout Amount shall be deemed equal to $200,000,000 minus the First Earnout Amount.

“Second Earnout Revenue” shall mean the Revenue during the six-month period commencing on January 1, 2008 and ending at the close of business on June 30, 2008.

“Total Earnout Amount” means the sum of the First Earnout Amount and the Second Earnout Amount.

(b) Deferred Payments.

(i) In addition to the amounts provided for in Sections 1.6(a) and 1.6(d), each Company Stockholder shall be entitled to receive the following amounts (the “Deferred Payments”):

(1) On the First Deferred Payment Date, an amount (the “Initial Deferred Payment”) equal to such Company Stockholder’s Pro Rata Portion (as defined in Section 7.1) of the First Earnout Amount, subject to any set-off pursuant to Article VII; and

(2) On the Second Deferred Payment Date, an amount (the “Final Deferred Payment”) equal to such Company Stockholder’s Pro Rata Portion (as defined in Section 7.1) of the Second Earnout Amount, subject to any set-off pursuant to Article VII.

(ii) Notwithstanding the foregoing, no amount shall be paid to a Company Stockholder pursuant to this Section 1.7(b) unless and until such Company Stockholder shall have surrendered such Company Stockholder’s Certificates and delivered a duly completed letter of transmittal in accordance with Section 1.8(c).

(c) Calculation of Earnout Amount. (i) On or prior to thirty (30) calendar days after the respective earnout period (forty-five (45) calendar days in the case of the first earnout period), Parent shall cause to be prepared and delivered to the Stockholders’ Representative a statement setting forth Parent’s calculation of the Earnout Amount (the “Earnout Statement”), together with reasonable supporting information.

(ii) After receipt of the Earnout Statement, the Stockholders’ Representative shall have thirty (30) calendar days to review the Earnout Statement. Unless the Stockholders’ Representative delivers written notice (the “Dispute Notice”) to Parent setting forth the items disputed by the Stockholders’ Representative on or prior to the 30^th calendar day after delivery of the Earnout Statement, the Stockholders’ Representative will be deemed to have accepted and agreed to the Earnout Statement, and the Earnout Statement (and the calculation of the Earnout Amount contained therein) will be final, binding and conclusive; provided, however, with respect to the First Earnout Amount, the Stockholders’ Representative may, upon delivery of written notice to Parent during such thirty-day period, elect to resolve such First Earnout Amount at the same time

-6-

that the Second Earnout Amount is resolved. During such thirty-day period, Parent shall provide the Stockholders’ Representative with reasonable access to Parent’s books, records and personnel in order to permit the Stockholders’ Representative to verify the calculation of the Earnout Amount. If the Stockholders’ Representative delivers a Dispute Notice in a timely manner, Parent and the Stockholders’ Representative will, within thirty (30) calendar days following delivery of such notice (the “Resolution Period”), attempt in good faith to resolve their differences in writing with respect to the items specified in the Dispute Notice (the “Disputed Items”). Any resolution by Parent and the Stockholders’ Representative during the Resolution Period as to any Disputed Items will be final, binding and conclusive.

(iii) If Parent and the Stockholders’ Representative do not resolve all Disputed Items by the end of the Resolution Period, then all Disputed Items remaining in dispute will be promptly submitted to KPMG LLP (the “Neutral Arbitrator”). If requested by the Neutral Arbitrator, Parent and the Stockholders’ Representative agree to execute a reasonable engagement letter. The Neutral Arbitrator shall act as an arbitrator to determine only those Disputed Items remaining in dispute, consistent with this Section 1.7(c) and shall request a statement from each of Parent and the Stockholders’ Representative regarding such Disputed Items. Each of Parent and the Stockholders’ Representative will pay its own fees and expenses incurred with respect to the resolution of the Disputed Items. All fees and expenses relating to the work, if any, to be performed by the Neutral Arbitrator will be allocated between Parent and the Stockholders’ Representative in the same proportion that (i) the extent to which the Disputed Items so submitted to the Neutral Arbitrator are unsuccessfully disputed by each such party (as finally determined by the Neutral Arbitrator) bears to (ii) the total amount of such Disputed Items so submitted. The Neutral Arbitrator will deliver to Parent and the Stockholders’ Representative a written determination (such determination to include a work sheet setting forth all material calculations used in arriving at such determination and to be based on independent review and audit of the Revenue upon which the Earnout Amount is based) of the Disputed Items by the Neutral Arbitrator within forty-five (45) calendar days after receipt of such Disputed Items (or as soon thereafter as practicable), which determination will be final, binding and conclusive and judgment may be entered on the award.

(d) Obligations of Parent. Parent shall use commercially reasonable efforts to market, promote, sell and distribute the IPD Devices in the United States, and such efforts shall include, to the extent commercially reasonable, (i) the development of marketing, sales and training materials, as Parent reasonably deems appropriate, for the IPD Devices, (ii) educating medical professionals specializing in spinal procedures on the use of the IPD Devices, and (iii) displaying the IPD Devices at meetings where attending medical professionals specialize in spinal procedures; provided, however, it shall not be deemed to be commercially reasonable to take any action if to do so would violate applicable Legal Requirements or any intellectual property rights of any third party.

(e) No Security. The parties understand and agree that (i) the Per Share Earnout Amounts payable under this Section 1.7 are an integral part of the Merger consideration payable hereunder, (ii) the rights to receive such amounts will not be represented by any form of certificate, are not transferable, except by operation of law

-7-

(including, without limitation, laws relating to descent and distribution, divorce and community property), and do not constitute an equity or ownership interest in Parent or the Surviving Corporation, (iii) no Company Stockholder shall have any rights as a security holder of the Surviving Corporation or Parent as a result of such Company Stockholder’s right to receive the Per Share Earnout Amounts, and (iv) no interest is payable with respect to the Per Share Earnout Amounts.

(f) Acceleration. The Earnout Amount of $200,000,000, less any Earnout Amount previously paid, subject to any set-off pursuant to Article VII, shall become immediately due and payable by Parent, such amount to be paid within three (3) business days of any of the following: (i) Parent or the Surviving Corporation commences any proceeding in bankruptcy or for dissolution, liquidation, winding-up, or other relief under state or federal bankruptcy laws; (ii) such proceedings are commenced against Parent or the Surviving Corporation, or a receiver or trustee is appointed for Parent or the Surviving Corporation or a substantial part of its respective property, and such proceeding or appointment is not dismissed or discharged within sixty (60) days after its commencement, (iii) Parent or the Surviving Corporation is unable to, or admits in writing its inability to, pay its debts when they become due; (iv) Parent or the Surviving Corporation makes an assignment for the benefit of creditors, or petitions or applies to any tribunal for the appointment of a custodian, receiver or trustee for it or a substantial portion of its assets or has a receiver, custodian or trustee appointed for all or a substantial portion of its assets; (v) a Change of Control; or (vi) Parent or the Surviving Corporation takes any action effectuating, approving or consenting to any of the foregoing.

1.8 Surrender of Certificates.

(a) Exchange Agent. Parent shall select its transfer agent or another nationally recognized exchange agent to act as the exchange agent (the “Exchange Agent”) in the Merger, which agent shall be reasonably acceptable to the Company.

(b) Parent to Provide Cash. Prior to the Effective Time, Parent shall enter into an agreement with the Exchange Agent which shall provide that, prior to the Effective Time, Parent shall make available to the Exchange Agent for exchange in accordance with this Article I, the Merger Consideration (as defined in Section 7.1), less the sum of (i) the Representative Reimbursement Amount (as defined in Section 7.1), and (ii) the amount to be deposited in escrow pursuant to the Management Escrow Agreement in exchange for Company Capital Stock and Company Options. The portion of the Representative Reimbursement Amount contributed following the Effective Time with respect to each Company Stockholder (as defined in Section 7.1) as of immediately prior to the Effective Time shall be in proportion to the aggregate amount of the Merger Consideration each such stockholder would otherwise be entitled to receive in the Merger by virtue of ownership of outstanding shares of Company Capital Stock and Company Options immediately prior to the Effective Time (treating, for purposes of this calculation, all Company Options and Company Restricted Stock as having fully vested and with respect to Company Options net of exercise prices). Any cash deposited with the Exchange Agent shall hereinafter be referred to as the “Exchange Fund.”

-8-

(c) Exchange Procedures. Within two (2) business days following the Effective Time, Parent shall make available for hand pick-up from the Exchange Agent and cause the Exchange Agent to mail to each holder of record (as of the Effective Time) of a certificate or certificates or an instrument or instruments (the “Certificates”), which immediately prior to the Effective Time represented (i) outstanding shares of Company Capital Stock whose shares were converted into the right to receive the Merger Consideration pursuant to Section 1.6(a) and (ii) the Company Options which were converted into the right to receive the Merger Consideration pursuant to Section 1.6(d): (A) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as are reasonably acceptable to the Company) and (B) instructions for use in effecting the surrender of the Certificates in exchange for cash constituting the Merger Consideration (less the Representative Reimbursement Amount with respect to such Company Stockholder in accordance with Article VII, and amounts to be deposited in escrow pursuant to the Management Escrow Agreement) (including a means of hand delivery). Upon surrender of Certificates for cancellation to the Exchange Agent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto and such other documents as may reasonably be required by the Exchange Agent, the holder of record of such Certificates shall be entitled to receive, in exchange therefor, the amount of cash constituting the Merger Consideration to which such holder is entitled pursuant to Section 1.6 (less the Representative Reimbursement Amount with respect to such Company Stockholder in accordance with Article VII and amounts to be deposited in escrow pursuant to the Management Escrow Agreement), and the Certificates so surrendered shall forthwith be canceled. No interest shall be paid or accrued on any cash constituting the Merger Consideration, other than with respect to amounts to be deposited in escrow pursuant to the Management Escrow Agreement. At the election of the respective Company Stockholder, the Exchange Agent shall make the foregoing payment by wire transfer to the extent that the aggregate amount owed to any such holder at the Closing is in excess of $1,000,000. Until so surrendered, outstanding Certificates will be deemed from and after the Effective Time, for all corporate purposes, to evidence the right to receive the Merger Consideration and the Earnout Amount into which such securities shall have been so converted.

(d) Required Withholding. Each of Parent, the Exchange Agent and the Surviving Corporation shall be entitled to deduct and withhold from the Merger Consideration and any other consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of Company Capital Stock or Company Options such amounts as may be required to be deducted or withheld therefrom under the Internal Revenue Code of 1986, as amended (the “Code”) or under any provision of state, local or foreign Tax law or under any other applicable Legal Requirement (as defined in Section 2.2(d)). To the extent such amounts are so deducted or withheld, the amount of such consideration shall be treated for all purposes under this Agreement as having been paid to the Person (as defined in Section 9.2(d)) to whom such consideration would otherwise have been paid.

-9-

(e) No Liability. Notwithstanding anything to the contrary in this Section 1.8, neither the Exchange Agent, the Surviving Corporation nor any party hereto shall be liable to a holder of shares of Company Capital Stock for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar law.

(f) Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Parent; provided, however, that no such investment or loss thereon shall affect the amounts payable to holders of the Company’s securities pursuant to this Article I. Any interest and other income resulting from such investment shall become a part of the Exchange Fund, and any amounts in excess of the amounts payable to holders of the Company’s securities pursuant to this Article I shall promptly be paid to Parent.

(g) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Certificates twelve (12) months after the Effective Time shall, at the request of the Surviving Corporation, be delivered to the Surviving Corporation or otherwise according to the instruction of the Surviving Corporation, and any holders of the Certificates who have not surrendered such Certificates in compliance with this Section 1.8 shall after such delivery to Surviving Corporation look only to Parent and the Surviving Corporation for the amount of cash constituting the Merger Consideration pursuant to Section 1.6(a) with respect to the shares of Company Capital Stock, or Section 1.6(d) with respect to Company Options and the Earnout Amount pursuant to Section 1.7 with respect to such shares and Company Options formerly represented thereby. If any Certificate shall not have been surrendered immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Entity (as defined in Section 2.3(c)), any such portion of the Exchange Fund remaining unclaimed by holders of the Company’s securities immediately prior to such time shall, to the extent permitted by law, become the property of the Surviving Corporation free and clear of any claims or interest of any Person previously entitled thereto.

1.9 No Further Ownership Rights in Company Capital Stock. All cash paid upon the surrender for exchange of shares of Company Capital Stock and Company Options in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Company Capital Stock and Company Options, and there shall be no further registration of transfers on the records of the Surviving Corporation of shares of Company 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 Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall transfer in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof and, if required by Parent, the giving by the holder thereof of an indemnity undertaking with respect to any claim that may be made against it with respect to such Certificate, such amount of cash constituting the Merger Consideration and, at the applicable time, any amount payable pursuant to Section 1.7.

-10-

1.11 Further Action. At and after the Effective Time, the officers and directors of Parent and the Surviving Corporation will be authorized to execute and deliver, in the name and on behalf of the Company and Merger Sub, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of the Company and Merger Sub, any other actions and things to vest, perfect or confirm of record or otherwise in the Surviving Corporation any and all right, title and interest in, to and under any of the rights, properties or assets acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger.

(b) Tax Returns and Audits.

(i) Filing of Tax Returns. The Company and each of its Subsidiaries have prepared and timely filed with the appropriate taxing authority all required federal, state, local and foreign returns, estimates, information statements and reports (“Tax Returns”) relating to any and all Taxes concerning or attributable to the Company, its Subsidiaries or their respective operations and such Tax Returns have been completed and are accurate in accordance with applicable law in all material respects. Neither the Company nor any of its Subsidiaries are currently the beneficiaries of any extension of time within which to file any Tax Return. No claim has ever been made in writing by an authority in a jurisdiction where the Company or any of its Subsidiaries do not file Tax Returns that it is or may be subject to taxation by that jurisdiction.

(ii) Payment of Taxes. All Taxes due and owing by the Company and any of its Subsidiaries on or before the date hereof (whether or not shown on any Tax Return) have been paid. The unpaid Taxes of the Company and any of its Subsidiaries (A) did not, as of the date of the Company Balance Sheet, exceed the reserve for Tax liability (rather than any reserve for deferred Taxes established to reflect timing differences between book and Tax income) set forth on the face of the Company Balance Sheet (rather than any notes thereto), and (B) will not exceed that reserve as adjusted for the passage of time through the Closing Date in accordance with the past custom and practice of the Company in filing its Tax Returns. Since the date of the Company Balance Sheet, neither the Company nor any of its Subsidiaries has incurred any liability for Taxes outside the ordinary course of business consistent with past practice.

(a) SEC Filings. Parent has filed all required registration statements, prospectuses, reports, schedules, forms, statements and other documents (including exhibits and all other information incorporated by reference) required to be filed by it with

-37-

the SEC since February 1, 2003. Parent has made available to the Company all such registration statements, prospectuses, reports, schedules, forms, statements and other documents in the form filed with the SEC that are not publicly available through the SEC’s ▇▇▇▇▇ database. All such required registration statements, prospectuses, reports, schedules, forms, statements and other documents are referred to herein as the “Parent SEC Reports.” As of their respective dates, the Parent SEC Reports complied as to form in all material respects with the requirements of the Securities Act, or the Exchange Act, as the case may be, and the rules and regulations of the SEC thereunder applicable to such Parent SEC Reports. The Parent SEC Reports did not at the time they were filed (or if amended or superseded by a filing prior to the date of this Agreement then on the date of such filing) contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. As of the date hereof, none of Parent’s Subsidiaries is required to file any forms, reports or other documents with the SEC. As of the date hereof, Parent has previously furnished to the Company a complete and correct copy of any amendments or modifications which have not yet been filed with the SEC, but which are required to be filed, to agreements, documents or other instruments which previously had been filed by Parent with the SEC pursuant to the Securities Act or the Exchange Act. As of the date hereof, there are no unresolved comments issued by the staff of the SEC with respect to any of the Parent SEC Reports.

(b) Financial Statements. Each of the consolidated financial statements (including, in each case, any related notes thereto) contained in the Parent SEC Reports (the “Parent Financials”): (i) complied as to form in all material respects with the published rules and regulations of the SEC with respect thereto, (ii) was prepared in accordance with GAAP applied on a consistent basis throughout the periods involved (except as may be indicated in the notes thereto or, in the case of unaudited interim financial statements, as may be permitted by the SEC on Form 10-Q, 8-K or any successor form under the Exchange Act), and (iii) fairly presented, in all material respects, the consolidated financial position of Parent and its consolidated Subsidiaries as at the respective dates thereof and the consolidated results of Parent’s operations and cash flows for the periods indicated (subject, in the case of unaudited statements, to normal year-end audit adjustments, as permitted by GAAP and the applicable rules and regulations promulgated by the SEC). The balance sheet of Parent contained in the Parent SEC Reports as of September 30, 2006, is hereinafter referred to as the “Parent Balance Sheet.” Other than liabilities (A) disclosed in the Parent SEC Reports or (B) incurred since the date of the Parent Balance Sheet in the ordinary course of business consistent with past practice, neither Parent nor any of its Subsidiaries has any liabilities (absolute, accrued, contingent or otherwise) of a nature required by GAAP to be disclosed on a consolidated balance sheet or in the notes thereto which, individually or in the aggregate, would be reasonably expected to have a Material Adverse Effect on Parent. Except as disclosed in the Parent SEC Reports, neither Parent nor any of its Subsidiaries is a party to, or has any commitment to become a party to, any “off-balance sheet arrangements” (as defined in Item 303(a) of Regulation S-K promulgated by the SEC).

(c) Internal Controls and Procedures. Parent has established and maintains disclosure controls and procedures and internal control over financial reporting

-38-

as such terms are defined and as required by Rules 13a 15 and 15d 15 under the Exchange Act. Parent’s disclosure controls and procedures are reasonably designed to ensure that all material information required to be disclosed by Parent in the reports that it files or furnishes under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that all such material information is accumulated and communicated to Parent’s management as appropriate to allow timely decisions regarding required disclosure and to make the certifications required pursuant to Sections 302 and 906 of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act. Parent’s management has completed an assessment of the effectiveness of Parent’s internal controls over financial reporting in compliance with the requirements of Section 404 of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act for the fiscal year ended December 31, 2005, and such assessment concluded that such controls were effective and Parent’s independent registered accountant has issued (and not subsequently withdrawn or qualified) an attestation report concluding that Parent maintained effective internal controls over financial reporting as of December 31, 2005. The principal executive officer and principal financial officer of Parent have made all certifications required by the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act and any related rules and regulations promulgated by the SEC. Parent has established and maintains, adheres to and enforces a system of internal control over financial reporting, which are effective in providing reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP, including policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of Parent and its Subsidiaries, (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of Parent and its Subsidiaries are being made only in accordance with appropriate authorizations of management and the Board of Directors of Parent, and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of Parent’s assets that could have a material effect on the financial statements of Parent and its Subsidiaries.

(a) No Infringement. To the Knowledge of Parent, as of the date hereof, the products, services and operations of Parent do not infringe or misappropriate the valid and enforceable Intellectual Property of any third party where such infringement or misappropriation, individually or in the aggregate, would be reasonably expected to have a Material Adverse Effect on Parent.

-39-

(b) No Impairment. To the Knowledge of Parent, the consummation of the Merger will not result in the termination or breach of any Contract directly related to Intellectual Property to which Parent is a party, which termination or breach would reasonably be expected to have a Material Adverse Effect on Parent.

(c) All Necessary Intellectual Property. To the Knowledge of Parent, Parent and its Subsidiaries own or otherwise have sufficient rights to all Intellectual Property used in and/or necessary to the conduct of the business of Parent and its Subsidiaries as it currently is conducted, and as it is currently planned to be conducted by Parent and its Subsidiaries, except as would not reasonably be expected to have a Material Adverse Effect on Parent.

(d) No Notice of Infringement. To the Knowledge of Parent, neither Parent nor any of its Subsidiaries has received notice from any third party that the operation of the business of Parent or any of its Subsidiaries or any act, product or service of Parent or any of its Subsidiaries, infringes or misappropriates the Intellectual Property of any third party or constitutes unfair competition or unfair trade practices under the laws of any jurisdiction except as would not otherwise reasonably be expected to have a Material Adverse Effect on Parent.

(e) Proprietary Information Agreements. Parent and its Subsidiaries have taken commercially reasonable steps to protect Parent’s and its Subsidiaries’ rights in Parent’s confidential information and trade secrets that it wishes to protect or any trade secrets or confidential information of third parties provided to Parent or any of its Subsidiaries, and, without limiting the foregoing, each of Parent and its Subsidiaries has and enforces a policy requiring each Employee to execute a proprietary information and confidentiality agreement substantially in Parent’s standard form of confidentiality and proprietary information and invention disclosure and assignment agreement, and, to the Knowledge of Parent, all Employees of Parent and any of its Subsidiaries who are involved in the development of material Intellectual Property of the Parent or its Subsidiaries have executed such an agreement, except where the failure to do any of the foregoing is not reasonably expected to have a Material Adverse Effect on Parent.

3.9 Availability of Funds. Parent has made available to the Company a true, accurate, complete and fully executed copy of a commitment letter (the “Financing Commitment”), pursuant to which, subject to the terms and conditions thereof, Bank of America, N.A. (the “Lender”) has committed to provide Parent with financing (the “Financing”). As of the date hereof, the Financing Commitment is in full force and effect and has not been withdrawn or terminated or otherwise amended or modified in any respect and Parent is not in breach of any conditions set forth therein. As of the date of this Agreement, no event has occurred which, with or without notice, lapse of time or both, would constitute a breach on the part of Parent under any term or condition of the Financing Commitment. The proceeds from the Financing, together with cash on hand, constitute all of the financing required to be provided by Parent for the consummation of the transactions contemplated hereby, and are sufficient for the satisfaction of Parent’s obligations to pay the Merger Consideration and the Earnout Amount.

(a) For the period of six (6) years following the Effective Time, Parent will cause the Surviving Corporation to indemnify and hold harmless each person who is now, or has been at any time prior to the date of this Agreement or who becomes, prior to the Effective Time, an officer, director or employee of the Company or any of its Subsidiaries (the “Company Indemnified Parties”) against all losses, claims, damages, costs, expenses, liabilities or judgments or amounts that are paid in settlement, in each case to the extent actually and reasonably incurred with the approval of the indemnifying party, which approval shall not be unreasonably withheld or delayed (the “Company Indemnified Liabilities”) of or in connection with any claim, action, suit, proceeding or investigation by reason of the fact that such person is or was a director, officer or employee of the Company or any of its Subsidiaries, whether pertaining to any matter existing or occurring at or prior to the Effective Time and whether asserted or claimed prior to, or at or after the Effective Time and all Company Indemnified Liabilities based on, or relating to this Agreement or the transactions contemplated hereby (to the extent that such losses, claims, damages, costs, expenses, liabilities or judgments or amounts arose from or are related to this Agreement or the transactions contemplated hereby), in each case to the full extent a corporation is permitted by Section 145 of the DGCL to indemnify its own directors, officers and employees (the “Company Indemnified Proceedings”). In the event any Company Indemnified Party is or becomes involved in any Company Indemnified Proceeding, Parent shall, or shall cause the Surviving Corporation to, pay expenses in advance of the final disposition of any such Company Indemnified Proceeding to each Company Indemnified Party to the full extent permitted by law upon receipt of any undertaking contemplated by Section 145 of the DGCL. Subject to the foregoing, in the event any such Company Indemnified Proceeding is brought against any Company Indemnified Party, (i) the Company Indemnified Parties may retain counsel of their choosing, who shall be reasonably acceptable to Parent, (ii) Parent shall, or shall cause the Surviving Corporation to, pay all reasonable and documented fees and expenses of one counsel for all of the Company Indemnified Parties with respect to each such Company Indemnified Proceeding unless there is, under applicable standards of professional conduct, a conflict on any significant issue between the positions of any two or more Company Indemnified Parties, in which case Parent shall pay the fees of such additional counsel required by such conflict, promptly as statements therefor are received; provided, however, that neither Parent nor the Surviving Corporation shall be liable for any settlement of any claim effected without its written consent, which consent shall not be unreasonably withheld or delayed. Any Company Indemnified Party wishing to claim indemnification under this Section 5.8(a) upon becoming aware of any such Company Indemnified Proceeding shall promptly notify Parent and the Surviving Corporation (but the failure to so notify Parent or the Surviving Corporation shall not relieve Parent or the

-51-

Surviving Corporation from any liability it may have under this Section 5.8(a) except to the extent such failure prejudices Parent or the Surviving Corporation), and shall deliver to Parent and the Surviving Corporation the undertaking contemplated by Section 145 of the DGCL.

(b) For a period of six (6) years following the Effective Time, Parent will, and will cause the Surviving Corporation to, fulfill and honor in all respects the obligations of the Company pursuant to any indemnification agreements between the Company and the Company Indemnified Parties, subject to applicable law. For a period of six (6) years following the Effective Time, the Certificate of Incorporation and Bylaws of the Surviving Corporation will contain provisions with respect to exculpation and indemnification that are at least as favorable to the Company Indemnified Parties as those contained in the Certificate of Incorporation and Bylaws of the Company as in effect on the date hereof, which provisions will not be amended, repealed or otherwise modified in any manner that would adversely affect the rights thereunder of Company Indemnified Parties.

(c) For six (6) years after the Effective Time, Parent will, or will cause the Surviving Corporation to, maintain directors’ and officers’ liability insurance covering those Persons who are covered by the Company’s directors’ and officers’ liability insurance policy as of the date hereof in an amount and on terms no less favorable than those applicable to the current directors and officers of the Company; provided, however, neither Parent nor the Surviving Corporation shall be required to pay an annual premium for the (“D&O Insurance”) in excess of 200% of the annual premium currently paid by the Company; provided, further, if such coverage cannot be obtained for such amounts, Parent shall provide the maximum amount of coverage as may be obtained for such amounts. In lieu of the foregoing, Parent may obtain, or request that the Company obtain at Parent’s expense, from such insurance carrier extended reporting period coverage under the Company’s existing officers’ and directors’ insurance policies.

(d) This Section 5.8 is intended to be for the benefit of, and shall be enforceable by the Company Indemnified Parties and their heirs and personal representatives and shall be binding on Parent and the Surviving Corporation and its successors and assigns. In the event Parent or the Surviving Corporation or its successor or assign (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each case, proper provision shall be made so that the successor and assign of Parent or the Surviving Corporation, as the case may be, honor the obligations set forth with respect to Parent or the Surviving Corporation, as the case may be, in this Section 5.8.

5.9 Certain Tax Matters.

(a) Preparation and Filing of Tax Returns; Payment of Taxes. Parent shall prepare or cause to be prepared and timely file all Tax Returns of the Company for Pre-Closing Tax Periods that are filed after the Closing Date and, subject to the Company Stockholders’ indemnification obligations hereunder, shall pay all Taxes due with respect to such Tax Returns. Parent shall permit the Stockholders’ Representative to review and comment on each material Tax Return prior to filing.

If, subsequent to the Closing, any of Parent, the Company or the Company Stockholders receives notice of a claim by any Governmental Entity, that, if successful, might result in an indemnity payment hereunder (a “Tax Claim”), then within fifteen (15) days after receipt of such notice, the party receiving such notice shall give written notice of such Tax Claim to the other parties. Parent shall have the right to control the conduct and resolution of any such Tax Claim relating to a Tax Period ending on or prior to the Closing Date; provided, however, that if the resolution of any such Tax Claim (or any portion thereof) may affect the Taxes of the Company for a Pre-Closing Tax Period, then the Stockholders’ Representative and Parent shall jointly control the conduct and resolution of such Tax Claim (or portion thereof). The Stockholders’ Representative and Parent shall jointly control the conduct and resolution of any Tax Claim relating to a Straddle Period as defined in Section 7.1. If the Company Stockholders elect not to participate in the conduct and resolution of any Tax Claim relating to a Pre-Closing Tax Period or a Straddle Period, the Stockholders’ Representative shall notify Parent in writing and Parent shall have the right to control the conduct and resolution of such Tax Claim; provided, however, that Parent shall keep the Stockholders’ Representative informed of all developments on a timely basis and Parent shall not resolve such Tax Claim in a manner that could reasonably be expected to have an adverse impact on the Indemnifying Parties’ indemnification obligations under this Agreement without the written consent of the Stockholders’ Representative, which shall not be unreasonably withheld. Each party shall bear its own costs incurred in participating in any proceeding relating to any Tax Claim.

(d) Transfer Taxes. All transfer, documentary, sales, use, stamp, registration and other substantially similar Taxes and fees (including any penalties and interest) incurred in connection with this Agreement (collectively, “Transfer Taxes”) shall be paid by the Company Stockholders when due, and the Company Stockholders will, at their own expense, file all necessary Tax Returns and other documentation with respect to all such Transfer Taxes and, if required by applicable law, Parent will, and will cause its affiliates to, join in the execution of any such Tax Returns and other documentation. The Company Stockholders shall provide Parent with evidence satisfactory to Parent that such Transfer Taxes have been paid by the Company Stockholders.

(e) Characterization of Payments. Any payments made to any Parent Indemnified Party pursuant to this Agreement shall constitute an adjustment of the consideration paid for the Company Common Stock for Tax purposes and shall be treated as such by the parties hereto on their Tax Returns to the extent permitted by law.

7.4 Set-Off From Earnout Amount.

(a) The Earnout Amount shall be available to compensate each of the Indemnified Parties for any Losses suffered or incurred by each such Indemnified Party resulting from (i) any breach of any representation or warranty of the Company contained in Article II of this Agreement (as modified by the Company Disclosure Letter), (ii) any failure by the Company to perform or comply with any covenant or agreement of the Company contained in this Agreement prior to the Closing Date, (iii) any inaccuracy in the information contained in the Closing Certificate and (iv) the amount paid with respect to each Dissenting Share that exceeds the amount that would have been payable with respect to such Dissenting Share, were such share not a Dissenting Share (after taking into account any set-off pursuant to this Article VII).

(b) Notwithstanding anything to the contrary contained herein, the Earnout Amount shall not be available to compensate any of the Indemnified Parties for any Losses under Section 7.4(a)(i), and no Indemnified Party shall be entitled to recover from the Earnout Amount, unless and until the Indemnified Parties have incurred Losses in excess of $3,000,000 in the aggregate (the “Deductible Amount”), and with respect to any

-59-

given claim for Losses, such claim is individually in excess of $35,000 (the “Threshold Amount”), after which the Earnout Amount, subject to the terms of this Article VII, shall be available to compensate each of the Indemnified Parties for any Losses, and, subject to the terms of this Article VII, the Indemnified Parties shall be entitled to seek recovery for such Losses that are in excess of the Deductible Amount in the aggregate and the Threshold Amount individually; provided, however, the limitations in this Section 7.4(b) shall not apply with respect to those representations and warranties contained in Sections 2.2, 2.3(a) and 2.12, and the Threshold Amount shall not apply with respect to those representations and warranties contained in Section 2.2. In no event shall the aggregate indemnification available to the Indemnified Parties under this Agreement exceed five percent (5%) of the sum of the Merger Consideration and the Total Earnout Amount, except in the case of fraud.

(c) Notwithstanding anything to the contrary contained herein: (i) no claim for Loss related to or arising from (A) the value or condition of any Tax asset of the Company or its Subsidiaries or (B) the ability of Parent, the Surviving Corporation or their affiliates to utilize such Tax asset following the Effective Time, shall be subject to a claim for recovery by any Indemnified Party hereunder; (ii) any Losses recoverable from the Earnout Amount hereunder shall be reduced in amount by any insurance proceeds that may be realized by any Indemnified Party, and Parent and the Indemnified Parties shall, as a condition to receiving any amounts from the Earnout Amount or otherwise seeking recovery hereunder, use all reasonable efforts to realize such benefits or proceeds; and (iii) if the amount of any Losses recoverable from the Earnout Amount hereunder gives rise to a reduction in the Tax liability of the Indemnified Party making the claim (a “Tax Benefit”) or an increase in the Tax liability of the Indemnified Party making the claim (a “Tax Detriment”), then the indemnification payment shall be reduced by the amount of the cumulative net Tax Benefit and/or increased by the amount of the cumulative net Tax Detriment actually realized by the Indemnified Party on its Tax Returns from the incurrence or payment of such Losses. For purposes of the foregoing sentence, (A) the Indemnified Party shall be deemed to have “actually realized” a net Tax Benefit to the extent that the amount of Taxes payable by the Indemnified Party as shown on the Indemnified Party’s Tax Return for the year in which the Losses are incurred, any year to which a deduction or loss attributable to such Losses is carried back, or any of the three (3) succeeding Tax years thereafter, is reduced below the amount of Taxes that the Indemnified Party would have been required to pay but for the incurrence or payment of such Losses, and (B) the Indemnified Party shall be deemed to have “actually realized” a net Tax Detriment to the extent that the amount of Taxes payable by the Indemnified Party as shown on the Indemnified Party’s Tax Return for the year in which the Losses are incurred or any of the five (5) succeeding Tax years thereafter is increased over the amount of Taxes that the Indemnified Party would have been required to pay but for the incurrence or payment of such Losses. If the cumulative Tax Benefit or Tax Detriment is actually realized in a year other than that in which the indemnification payment is made, the Indemnified Party shall pay the amount of the cumulative net Tax Benefit to the indemnifying party, or the indemnifying party shall pay the amount of the cumulative net Tax Detriment to the Indemnified Party, as the case may be, within 30 days of the filing of the Tax Return in which the net Tax Benefit or net Tax Detriment is actually realized. If the Indemnified Party has other losses, deductions, credits or similar items available to it,

-60-

the losses, deductions, credits or similar items attributable to the incurrence or payment of the Losses shall be treated as the last items utilized to produce a net Tax Benefit. Notwithstanding the foregoing, if, as a result of a “final determination” within the meaning of Section 1313(a) of the Internal Revenue Code, the amount of any such net Tax Benefit is decreased or the amount of any such net Tax Detriment is increased, then the Indemnified Party or the indemnifying party, as the case may be, shall pay to the other party an amount such that the aggregate amount paid to the other party equals the amount that would have been paid had the result of the “final determination” been taken into account in the original calculation of the amount of net Tax Benefit or net Tax Detriment resulting from the incurrence of the Losses.

(d) No Losses shall be recoverable hereunder that constitute punitive, incidental, indirect or special damages, except in the event of an intentional breach of this Agreement or fraud.

(e) All claims for recovery for any Loss or Losses from the Earnout Amount under this Agreement shall be made pursuant to and in accordance with, and be governed by the terms of, this Agreement.

7.5 Exclusive Remedy. Except in the event of fraud, (a) set-off from the Earnout Amount in an amount not to exceed five percent (5%) of the sum of the Merger Consideration and the Total Earnout Amount shall be the sole and exclusive remedy of the Indemnified Parties for any Losses incurred by any Indemnified Party, and (b) no Company Stockholder shall be liable to Parent, the Surviving Corporation or any Indemnified Party for any damages or other remedies arising out of, in connection with or related to this Agreement or the transactions contemplated hereby or any representation, warranty, covenant or agreement contained herein.

7.6 Distribution of Earnout Amount. Upon the First Deferred Payment Date, there shall be set-off from the Initial Deferred Payment an amount, which, in the reasonable judgment of Parent, subject to the objection of the Stockholders’ Representative and the subsequent litigation of the claim in the manner provided in Section 7.10, is necessary to satisfy any unsatisfied claims specified in any Officer’s Certificate delivered to the Stockholders’ Representative on or prior to the earlier of the Indemnification Termination Date and the First Deferred Payment Date; provided, however, that such amount shall not exceed five percent (5%) of the sum of (x) the Merger Consideration and (y) the First Earnout Amount, and any such excess for which no set-off is made shall, subject to the limitations in Section 7.4(b), be eligible for set-off against the Final Deferred Payment. As soon as all such claims have been resolved, Parent shall deliver the remaining portion of the Initial Deferred Payment, if any, not required to satisfy such claims to the Company Stockholders. Upon the Second Deferred Payment Date, the Final Deferred Payment shall promptly be delivered to the Company Stockholders; provided, however, that there shall be set-off from the Final Deferred Payment an amount, which, in the reasonable judgment of Parent, subject to the objection of the Stockholders’ Representative and the subsequent litigation of the claim in the manner provided in Section 7.10, is necessary to satisfy any unsatisfied claims specified in any Officer’s Certificate delivered to the Stockholders’ Representative on or prior to the earlier of the

-61-

Indemnification Termination Date and the Final Deferred Payment Date (including any amount provided for in the proviso to the first sentence of this Section 7.6); provided, however, that such amount, together with all amounts set-off with respect to resolved claims pursuant to this Section 7.6, shall not exceed five percent (5%) of the sum of (x) the Merger Consideration and (y) the Total Earnout Amount. As soon as all such claims have been resolved, Parent shall deliver the remaining portion of the Second Earnout Amount not required to satisfy such claims by Indemnified Parties hereunder to the Company Stockholders at such time that any such claims are resolved. Deliveries to the Company Stockholders pursuant to this Section 7.6 shall be made in proportion to their respective Pro Rata Portion of the amount distributed, with each amount rounded to the nearest whole cent ($0.01).

7.7 Stockholders’ Representative.

(a) By virtue of the approval and adoption of this Agreement by the requisite consent of the Company Stockholders, each of the Company Stockholders (other than such Company Stockholders, if any, who have perfected dissenters’ or appraisal rights under Delaware or the applicable laws of the State of California) shall be deemed to have agreed to appoint ▇▇▇▇▇▇ ▇. ▇▇▇▇▇ as its agent and attorney-in-fact (the “Stockholders’ Representative”) for and on behalf of the Stockholders to give and receive notices and communications, to authorize payment to any Indemnified Party from the Earnout Amount in satisfaction of claims by any Indemnified Party, to object to such payments, 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, to assert, negotiate, enter into settlements and compromises of, and demand arbitration and comply with orders of courts and awards of arbitrators with respect to, any other claim by any Indemnified Party against any Company Stockholder or by any such Company Stockholder against any Indemnified Party or any dispute between any Indemnified Party and any such Stockholder, in each case relating to this Agreement or the transactions contemplated hereby, and to take all other actions that are either (i) necessary or appropriate in the judgment of the Stockholders’ Representative for the accomplishment of the foregoing or (ii) specifically mandated by the terms of this Agreement. Such agency may be changed by the Company Stockholders with the right to a majority of the Pro Rata Portions of the Earnout Amount; provided, however, that the Stockholders’ Representative may not be removed unless holders of a two-thirds interest of the Earnout Amount agree to such removal and to the identity of the substituted agent. Notwithstanding the foregoing, the Stockholders’ Representative may resign at any time by providing written notice of intent to resign to the Company Stockholders, which resignation shall be effective upon the earlier of (A) thirty (30) calendar days following delivery of such written notice or (B) the appointment of a successor by the holders of a majority in interest of the Earnout Amount. No bond shall be required of the Stockholders’ Representative, and the Stockholders’ Representative shall not receive any compensation for its services.

(b) The Stockholders’ Representative shall not be liable to the Company Stockholders for any act done or omitted hereunder as Stockholders’ Representative while acting in good faith and in the exercise of reasonable judgment, even if such act or omission constitutes negligence on the part of such Stockholders’ Representative. The

-62-

Stockholders’ Representative shall only have the duties expressly stated in this Agreement and shall have no other duty, express or implied. The Stockholders’ Representative may engage attorneys, accountants and other professionals and experts. The Stockholders’ Representative may in good faith rely conclusively upon information, reports, statements and opinions prepared or presented by such professionals, and any action taken by the Stockholders’ Representative based on such reliance shall be deemed conclusively to have been taken in good faith and in the exercise of reasonable judgment. The Company Stockholders shall indemnify the Stockholders’ Representative and hold the Stockholders’ Representative harmless against any loss, liability or expense incurred on the part of the Stockholders’ Representative (so long as the Stockholders’ Representative was acting in good faith in connection therewith) and arising out of or in connection with the acceptance or administration of the Stockholders’ Representative’s duties hereunder, including the reasonable fees and expenses of any legal counsel retained by the Stockholders’ Representative (“Stockholders’ Representative Expenses”). The Stockholders’ Representative shall have the right to retain Stockholders’ Representative Expenses from the Representative Reimbursement Amount prior to any distribution to the Company Stockholders. A decision, act, consent or instruction of the Stockholders’ Representative, including an amendment, extension or waiver of this Agreement pursuant to Sections 8.4 or 8.5 hereof, shall constitute a decision of the Company Stockholders and shall be final, binding and conclusive upon the Company Stockholders.

(c) The Indemnified Parties shall be entitled to rely conclusively on the instructions and decisions of the Stockholders’ Representative with respect to the indemnification obligations of the Company Stockholders under this Article VII, including the defense or settlement of any claims or the making of payments with respect thereto, or as to any other actions required or permitted to be taken by the Stockholders’ Representative hereunder (including any amendment or waiver under Sections 8.4 and 8.5).

7.8 Third-Party Claims. In the event that an Indemnified Party becomes aware of a third party claim (a “Third Party Claim”) that the Indemnified Party reasonably believes may result in a demand for indemnification pursuant to this Article VII, Parent shall promptly notify the Stockholders’ Representative of such claim; provided, however, the failure of Parent to so give notice shall not relieve the Company Stockholders of their obligations under this Article VII, except to the extent that such failure has materially prejudiced the rights of the Company Stockholders. The Stockholders’ Representative may, at his or her election, undertake and conduct the defense of such Third Party Claim through counsel reasonably acceptable to the Indemnified Party, if the Stockholders’ Representative delivers notice to Parent and the Indemnified Party within thirty (30) calendar days after receipt of notice of the Third Party Claim, which notice shall specify that the Third Party Claim is one for which such Indemnified Party is entitled to indemnification pursuant to this Article VII; provided, however, the Stockholder Representative shall have no right to undertake and conduct the defense of such Third Party Claim if (a) any Losses in respect of such Third Party Claim are reasonably likely to exceed five percent (5%) of the sum of the Merger Consideration and the Total Earnout Amount, reduced by a reasonable estimate of the amount of all pending claims, or (b) it seeks as a remedy the imposition of an equitable remedy. Parent shall be entitled to

-63-

participate in, but not to determine or conduct, the defense of any Third Party Claim that Stockholders’ Representative elects to undertake and conduct pursuant to this Section 7.8. The Stockholders’ Representative shall not, without the prior written consent of the Indemnified Party, (i) enter into any settlement or compromise of such Third Party Claim that does not include as an unconditional term thereof the giving by the Person(s) asserting such claim to all Indemnified Parties of an unconditional release from all liability with respect to such claim, or (ii) settle or compromise any Third Party Claim if the settlement or compromise imposes equitable remedies or material obligations on the Indemnified Party other than financial obligations for which such Indemnified Party will be indemnified hereunder, or in any way restricts or adversely affects the future conduct or activity of the Indemnified Parties. If the Stockholders’ Representative does not so elect to undertake and conduct the defense of such Third Party Claim in accordance with the provisions of this Section 7.8, Parent shall undertake the defense of and use all reasonable efforts to defend such claim and shall keep the Stockholders’ Representative reasonably apprised of the status thereof; provided however, that Parent shall have the right in its reasonable discretion to settle any such claim; provided, further, that except with the consent of the Stockholders’ Representative, no settlement of any such Third Party Claim with third party claimants shall be determinative of the amount of Losses relating to such matter.

7.9 No Other Representations and Warranties.

(a) Each of the Parent and Merger Sub acknowledges and agrees that it has made its own inquiry and investigation into, and, based thereon, has formed an independent judgment concerning, the Company and its businesses and operations, and Parent and Merger Sub have been furnished with or given full access to such information about the Company and its businesses and operations as they requested. In connection with Parent’s and Merger Sub’s investigation of the Company and its businesses and operations, Parent, Merger Sub and their respective representatives have received from the Company or its representatives, certain projections and other forecasts for the Company and certain estimates, plans and budget information. Parent and Merger Sub acknowledge and agree that (i) there are uncertainties inherent in attempting to make such projections, forecasts, estimates, plans and budgets; (ii) Parent and Merger Sub are familiar with such uncertainties; and (iii) Parent and Merger Sub are taking full responsibility for making their own evaluations of the adequacy and accuracy of all estimates, projections, forecasts, plans and budgets so furnished to them or their representatives.

(b) Without limiting the generality of the foregoing, the Indemnified Parties shall have no claim or right to recovery pursuant to this Article VII or otherwise, and none of the Indemnified Parties or any other person shall have or be subject to any liability to Merger Sub, Parent, the Indemnified Parties or any other person, with respect to (i) any information, documents or materials furnished, delivered or made available by the Company or its Affiliates, officers, directors, employees, agents or advisors to Parent or Merger Sub, in certain “data rooms”, management presentations or any other form in contemplation of the transactions contemplated hereby or (ii) any projections, forecasts, estimates, plans or budgets of future revenue, expenses or expenditures, future results of operations (or any component thereof), future cash flows (or any component thereof) or

-64-

future financial condition (or any component thereof) of the Company or the future business, operations or affairs of the Company heretofore or hereafter delivered to or made available to Parent, Merger Sub or their respective representatives or Affiliates.

7.10 Resolution of Claims.

(a) In the case of any claim or claims for Losses (each a “Claim”) specified in an Officer’s Certificate pursuant to Section 7.6, the Stockholders’ Representative shall have thirty (30) calendar days after delivery of such Officer’s Certificate to deliver written notice (an “Objection Notice”) of objection to Parent, which shall state in reasonable detail the basis for such objection. If the Stockholders’ Representative shall fail to deliver an Objection Notice within such 30-day period, such Claim and such Losses shall be deemed to be final, binding and conclusive and Parent shall be entitled to retain the amount thereof from the Earnout Amount. If the Stockholders’ Representative shall timely deliver an Objection Notice, the Stockholders’ Representative and the Indemnified Party shall attempt in good faith for thirty (30) calendar days to agree upon the rights of the respective parties with respect to each of such claims. Any resolution by such Indemnified Party and the Stockholders’ Representative during such period will be final, binding and conclusive.

(b) If no such agreement can be reached after good faith negotiation, either the Indemnified Party or the Stockholders’ Representative may bring suit in the State courts of California and to the jurisdiction of the United States District Court for Northern District of California. Upon final nonappealable judicial resolution of such Claim and such Losses, Parent shall be entitled to retain the amount thereof from the Earnout Amount.

(e) by the Company, upon a breach of any representation, warranty, covenant or agreement on the part of Parent set forth in this Agreement, or if any representation or warranty of Parent shall have become untrue, in either case such that the conditions set forth in Section 6.2(a) or Section 6.2(b) would not be satisfied as of the time of such breach or as of the time such representation or warranty shall have become untrue, provided that if such inaccuracy in Parent’s representations and warranties or breach by Parent is curable by Parent prior to the End Date through the exercise of reasonable efforts, then the Company may not terminate this Agreement under this Section 8.1(e) prior to thirty (30) days following the receipt of written notice from the Company to Parent of such breach (it being understood that the Company may not terminate this Agreement pursuant to this Section 8.1(e) if it shall have materially breached this Agreement or if such breach by Parent is cured so that such conditions would then be satisfied); or

(f) by Parent, upon a breach of any representation, warranty, covenant or agreement on the part of the Company set forth in this Agreement, or if any representation or warranty of the Company shall have become untrue, in either case such that the conditions set forth in Section 6.3(a) or Section 6.3(b) would not be satisfied as of the time of such breach or as of the time such representation or warranty shall have become untrue, provided that if such inaccuracy in the Company’s representations and warranties or breach by the Company is curable by the Company prior to the End Date through the exercise of reasonable efforts, then Parent may not terminate this Agreement under this Section 8.1(f) prior to (30) days following the receipt of written notice from Parent to the Company of such breach (it being understood that Parent may not terminate this Agreement pursuant to this Section 8.1(f) if it shall have materially breached this Agreement or if such breach by the Company is cured so that such conditions would then be satisfied).

An exception or disclosure made in Company Disclosure Letter with regard to a representation of the Company, or in the Parent Disclosure Letter with regard to a representation of Parent or Merger Sub, shall be deemed made with respect to any other representation by such party to which such exception or disclosure is reasonably apparent.

(b) For purposes of this Agreement, the term “Affiliate” of a specified Person means a Person that directly or indirectly, through one or more intermediaries, controls, is controlled by, or is under common control with, the Person specified.

(c) For purposes of this Agreement, the term “Knowledge” means (i) with respect to the Company, with respect to any matter in question, the actual knowledge of ▇▇▇▇▇ ▇. ▇▇▇▇▇ (Chief Executive Officer), ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇ (Chief Financial Officer), T. ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇ (Vice President, Regulatory, Clinical Affairs and Quality Assurance), ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ (Director Administration and Human Resources), ▇▇▇▇▇ ▇. ▇▇▇▇▇ (Vice President, Research and Development) and ▇▇▇▇ ▇▇▇▇▇▇▇ (Director, Health Reimbursement); and (ii) with respect to Parent, with respect to any matter in question, the actual knowledge of the Chief Executive Officer, Director of Intellectual Property, Chief Financial Officer and General Counsel of Parent.

(d) For purposes of this Agreement, the term “Material Adverse Effect,” when used in connection with an entity, means a change, effect, event, occurrence, state of facts or development that, individually or in the aggregate with other such changes, effects, events, occurrences, states of facts or developments, is or is reasonably expected to be both material and adverse with respect to the financial condition, business, operations and results of operations of such entity taken as a whole together with its Subsidiaries or prevent, materially delay or materially impair the ability of such entity to consummate the transactions contemplated by this Agreement; provided, however, in no event shall any of the following, alone or in combination, be deemed to constitute, nor shall any of the following be taken into account in determining whether there has been or will be, a Material Adverse Effect on any entity: (i) any change or effect that is required pursuant to the terms and conditions of this Agreement, (ii) any change or effect that results from changes affecting any of the industries in which such entity operates generally or the United States or worldwide economy generally (which changes in each case do not disproportionately affect such entity in any material respect); (iii) any natural disaster or any acts of terrorism, sabotage, military action or war (whether or not declared) or any escalation or worsening thereof; (iv) failure to meet internal forecasts or financial projections; (v) any change or effect resulting from the announcement or pendency of the Merger, including loss of any employees, customers, sales representatives or distributors; or (vi) any change in stock price (but not the underlying causes thereof).

This Agreement may be executed in two 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 party, it being understood that all parties need not sign the same counterpart.

9.4 Entire Agreement; Third-Party Beneficiaries. This Agreement and the documents and instruments and other agreements among the parties hereto as contemplated by or referred to herein, including the Company Disclosure Letter and the Parent Disclosure Letter (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, it being understood that the Confidentiality Agreement shall continue in full force and effect until the Closing and shall survive any termination of this Agreement and (b) are not intended to confer upon any other Person any rights or remedies hereunder following the Effective Time, except such provisions that act for the benefit of the Company Indemnified Parties set forth in Section 5.8.

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 greatest extent possible, the economic, business and other purposes of such void or unenforceable provision.

9.6 Other Remedies. 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. 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.

9.7 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of California, regardless of the laws that might otherwise govern under applicable principles of conflicts of law thereof.

(b) EACH OF PARENT, THE COMPANY AND MERGER SUB IRREVOCABLY CONSENTS TO THE SERVICE OF THE SUMMONS AND COMPLAINT AND ANY OTHER PROCESS IN ANY OTHER ACTION OR PROCEEDING RELATING TO THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, ON BEHALF OF ITSELF OR ITS PROPERTY, BY THE PERSONAL DELIVERY OF COPIES OF SUCH PROCESS TO SUCH PARTY. NOTHING IN THIS SECTION 9.8 SHALL AFFECT THE RIGHT OF ANY PARTY TO SERVE LEGAL PROCESS IN ANY OTHER MANNER PERMITTED BY LAW.

9.9 Rules of Construction. The parties hereto agree that they have been represented by counsel during the negotiation 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.

9.10 Assignment. No party may assign either this Agreement or any of its rights, interests, or obligations hereunder without the prior written approval of the other parties. Any purported assignment in violation of this Section 9.10 shall be void. Subject to the preceding sentence, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns.

9.11 No Waiver. No failure or delay on the part of any party hereto in the exercise of any right hereunder will impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor will any single or partial exercise of any such right preclude other or further exercise thereof or of any other right.
