AGREEMENT AND PLAN OF MERGER

This AGREEMENT AND PLAN OF MERGER, dated as of June 2, 2009 (this “Agreement”), is by and among ev3 Inc., a Delaware corporation (“Parent”), Starsky Merger Sub, Inc., a California corporation and a direct wholly owned subsidiary of Parent (“Merger Co.”), Starsky Acquisition Sub, Inc., a California corporation and a direct wholly owned subsidiary of Parent (“Acquisition Co.”), Chestnut Medical Technologies, Inc., a California corporation (“Company”), and CMT SR, Inc., a California corporation (“Shareholder Representative”).

A. Each of the respective Boards of Directors of Parent, Merger Co., Acquisition Co. and Company has approved, and declared it advisable and in the best interests of its stockholders or shareholders, as the case may be, to consummate the business combination transaction and other transactions provided for herein, including the merger (the “Reverse Merger”) of Merger Co. with and into the Company and the immediately subsequent merger of Company with and into Acquisition Co. (the “Forward Merger”; together with the Reverse Merger, the “Merger”), in accordance with the laws of their respective states of incorporation, including the California Corporations Code (the “CCC”), and upon the terms and subject to the conditions set forth herein.

B. Parent and Company intend the Merger to qualify as a reorganization within the meaning of Section 368 of the Internal Revenue Code of 1986, as amended, and the rules and regulations promulgated thereunder (the “Code”).

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

D. Contemporaneously with the execution of this Agreement, as an inducement to Parent’s willingness to enter into this Agreement and incur the obligations set forth herein, certain of Company’s shareholders, which beneficially or of record hold an aggregate of approximately 66% of the outstanding shares of the capital stock of Company (on an as-converted to Company Common Stock basis), have entered into a voting agreement, dated as of the date hereof, with Parent (each, a “Voting Agreement”), pursuant to which, upon the terms set forth therein, such shareholders have agreed to vote their shares of Company Common Stock and Company Preferred Stock, as applicable, in favor of this Agreement and the transactions contemplated hereby.

Accordingly, and in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth herein and intending to be legally bound, the parties hereto agree as follows:

ARTICLE I.
The Merger

1.1 Effective Time of Merger. Subject to the provisions of this Agreement, an agreement of merger (the “First Agreement of Merger”) for the Reverse Merger shall be duly

prepared, executed by Company and Merger Co. and thereafter delivered to the Secretary of State of the State of California for filing, as provided in the CCC, on the Closing Date (as defined in Section 1.2). The Reverse Merger shall become effective upon the filing of the First Agreement of Merger with the Secretary of State of the State of California or at such time thereafter as is agreed upon in writing by Parent and Company and provided in the First Agreement of Merger (the “Effective Time”). Subject to the provisions of this Agreement, an agreement of merger (the “Second Agreement of Merger”) for the Forward Merger shall be duly prepared, executed by Company and Acquisition Co. and thereafter delivered to the Secretary of State of the State of California for filing, as provided in the CCC, on the Closing Date (as defined in Section 1.2) immediately after the Effective Time. The Forward Merger shall become effective upon the filing of the Second Agreement of Merger with the Secretary of State of the State of California or at such time thereafter as is agreed upon in writing by Parent and Company and provided in the Second Agreement of Merger (the “Second Effective Time”)

1.2 Closing. The closing of the Merger (the “Closing”) will take place at 10:00 a.m., California time, on the date (the “Closing Date”) that is the second Business Day after the satisfaction or waiver (subject to Applicable Law) of the conditions set forth in Article V (excluding conditions that, by their terms, are to be satisfied on the Closing Date but subject to the satisfaction or waiver of such conditions), unless another time or date is agreed to in writing by the parties hereto. The Closing shall be held at the offices of ▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, 3300 Plaza VII, ▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, unless another place is agreed to in writing by the parties hereto. For the purposes of this Agreement, “Business Day” shall mean each day other than a Saturday, Sunday or any other day when commercial banks in Minneapolis, Minnesota are authorized or required by law to close.

1.3 Effects of the Merger. At the Effective Time, Merger Co. shall be merged with and into Company and the separate existence of Merger Co. shall cease. At the Second Effective Time, Company as the surviving corporation in the Reverse Merger (the “First Surviving Corporation”) shall be merged with and into Acquisition Co. and the separate existence of the First Surviving Corporation shall cease and Acquisition Co. shall continue as the surviving corporation in the Merger. The Merger will have the effects set forth in the CCC. As used in this Agreement, “Constituent Corporations” shall mean each of Merger Co., Acquisition Co. and Company, and “Surviving Corporation” shall mean Acquisition Co., at and after the Second Effective Time, as the surviving corporation in the Merger and a direct wholly owned subsidiary of Parent. The parties intend the Merger (i.e., the Reverse Merger and the Forward Merger taken together as a single integrated transaction) to be treated as a tax-free reorganization pursuant to Section 368(a)(2)(D) of the Code and Revenue Ruling 2001-46, 2001-2 C.B. 321 (and any comparable provisions of any applicable state or local law); provided, however, that if the Merger is determined (within the meaning of Section 1313(a) of the Code) not to qualify as a tax-free reorganization, the parties intend the Reverse Merger and the Forward Merger each to be treated as separate transactions for income tax purposes pursuant to Revenue Ruling 90-95, 1990-2 C.B. 67 (and any comparable provisions of any applicable state or local law).

1.4 Articles of Incorporation. At the Second Effective Time, the articles of incorporation of Acquisition Co. as in effect immediately prior to the Second Effective Time shall be the articles of incorporation of the Surviving Corporation until thereafter changed or amended as provided therein or by Applicable Law except that the articles of incorporation shall

be amended so that the name of the Surviving Corporation shall be “Chestnut Medical Technologies, Inc.”.

1.5 By-Laws. At the Second Effective Time, the By-laws of Acquisition Co. as in effect immediately prior to the Second Effective Time shall be the By-laws of the Surviving Corporation until thereafter changed or amended as provided therein or by Applicable Law.

1.6 Officers and Directors of Surviving Corporation. The officers of Acquisition Co. as of the Second Effective Time shall be the officers of the Surviving Corporation, until the earlier of their resignation or removal or otherwise ceasing to be an officer or until their respective successors are duly appointed and qualified, as the case may be. The directors of Acquisition Co. as of the Second Effective Time shall be the directors of the Surviving Corporation until the earlier of their resignation or removal or otherwise ceasing to be a director or until their respective successors are duly elected and qualified.

ARTICLE II.
Effects of the Merger; Merger Consideration

2.1 Effect on Capital Stock.

(a) Cancellation of Certain Stock. At the Effective Time, by virtue of the Reverse Merger and without any action on the part of the holder of any shares of Company Common Stock or Company Preferred Stock, all shares of common stock, without par value, of Company (the “Company Common Stock”), series A preferred stock, without par value, of Company (the “Series A Preferred Stock”), series B preferred stock, without par value, of Company (the “Series B Preferred Stock”) and series C preferred stock, without par value, of Company (the “Series C Preferred Stock” and, collectively with the Series A Preferred Stock and Series B Preferred Stock, the “Company Preferred Stock” and, collectively with the Company Common Stock, the “Company Capital Stock”) that are owned by Company, or any direct or indirect wholly owned Subsidiary of Company, shall be canceled and shall cease to exist, and no cash or shares of common stock, par value $0.01 per share, of Parent (the “Parent Common Stock”) or other consideration shall be delivered in exchange therefor.

(b) Conversion of Company Preferred Stock. If the condition to the obligation of Parent, Merger Co. and Acquisition Co. to effect the Merger set forth in Section 5.2(d) is not satisfied prior to the Closing and Parent has waived the satisfaction of such condition, each share of Company Preferred Stock issued and outstanding immediately prior to the Effective Time (other than (i) shares to be canceled in accordance with Section 2.1(a) and (ii) Dissenting Shares) shall be, at the Effective Time by virtue of the Reverse Merger, canceled and extinguished and automatically converted into the right to receive the Liquidation Preference Payment applicable to such share, without interest, payable (A) such percentage that is equal to 100% minus the Closing Stock Percentage (the “Closing Cash Percentage”) in cash and (B) such percentage that is between 60% and 70% (inclusive) as is selected by Parent in its sole discretion and set forth in a written notice to Company delivered by Parent at least 3 days prior to the anticipated Closing Date (the “Closing Stock Percentage”) in shares of Parent Common Stock (assuming each share of Parent Common Stock has a value equal to the Applicable Denominator). Upon conversion of the shares of Company Preferred Stock pursuant to this Section 2.1(b) into the right to receive

the Liquidation Preference Payment in cash and shares of Parent Common Stock, all such shares of the Company Preferred Stock shall no longer be outstanding and shall automatically be canceled and extinguished and shall cease to exist, and each certificate previously representing any such shares shall thereafter represent only the right to receive the Liquidation Preference Payment in respect of such shares as provided in this Section 2.1(b) upon the surrender of the certificate representing such shares in accordance with Section 2.4(c) (or in the case of a lost, stolen or destroyed certificate, upon delivery of an affidavit (and bond, if required) in the manner provided in Section 2.4(k)). If the condition to the obligation of Parent, Merger Co. and Acquisition Co. to effect the Merger set forth in Section 5.2(d) is not satisfied prior to Closing and Parent has waived the satisfaction of such condition because shares of Company Preferred Stock have not converted and holders thereof will receive the Liquidation Preference Payment, the calculation of the Per Share Merger Consideration payable to the holders of Company Common Stock and Company Options immediately prior to the Effective Time will be adjusted such that the holders of Company Common Stock and Company Options immediately prior to the Effective Time will receive the benefit of the holders of Company Preferred Stock that are paid the Liquidation Preference Payment receiving less than the Per Share Merger Consideration that would have been payable if such holders of Company Preferred Stock had converted prior to the Effective Time.

(c) Conversion of Company Common Stock. Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than (i) shares to be canceled in accordance with Section 2.1(a) or (ii) Dissenting Shares) shall be, at the Effective Time by virtue of the Reverse Merger, canceled and extinguished and automatically converted into the right to receive (i) the Closing Date Per Share Consideration and (ii) the FDA Milestone Per Share Consideration (collectively, the “Per Share Merger Consideration”) that may be payable in respect of such share pursuant to this Agreement, if any, at the respective times and subject to the conditions and contingencies herein. Upon conversion of the shares of Company Common Stock pursuant to this Section 2.1(c), all such shares of the Company Common Stock shall no longer be outstanding and shall automatically be canceled and extinguished and shall cease to exist, and each certificate previously representing any such shares shall thereafter represent only the right to receive the Per Share Merger Consideration in respect of such shares upon the surrender of the certificate representing such shares in accordance with Section 2.4(c) (or in the case of a lost, stolen or destroyed certificate, upon delivery of an affidavit in the manner provided in Section 2.4(k)).

(d) Definitions.

(i) “Closing Date Cash Consideration” means an amount payable in cash equal to (A) the Closing Cash Percentage multiplied by the Closing Date Merger Consideration, less (B) the Representative Funds, less (C) any Closing Date Cash Adjustment Amount.

(ii) “Closing Date Merger Consideration” means (A) Seventy-Five Million Dollars ($75,000,000), plus (B) the amount of cash and cash equivalents held by the Company as of the Closing Date, plus (C) an amount equal to the aggregate of with respect to each Company Option (as defined below) which is outstanding immediately prior to the Effective Time (I) such Company Option’s exercise price per share multiplied by (II) the total

number of shares of Company Capital Stock issuable upon full exercise of such Company Options, less (D) the amount of Indebtedness of Company as of the Closing Date.

(iii) “Closing Date Stock Consideration” means that number of whole shares of Parent Common Stock equal to the quotient of (A) an amount equal to the Closing Stock Percentage multiplied by the Closing Date Merger Consideration, divided by (B) the Applicable Denominator, payable in validly issued, fully paid and non-assessable shares of Parent Common Stock. For purposes of this definition, the “Applicable Denominator” shall be determined as follows:

(A) If the Upfront Closing Price is at least 80% but not more than 120% of the Upfront Signing Price, then the Applicable Denominator shall equal the Upfront Closing Price;

(B) If the Upfront Closing Price is greater than 120% of the Upfront Signing Price, then the Applicable Denominator shall equal 120% of the Upfront Signing Price; and

(C) If the Upfront Closing Price is less than 80% of the Upfront Signing Price, then the Applicable Denominator shall equal 80% of the Upfront Signing Price.

The “Upfront Closing Price” shall equal the average of the closing prices of Parent Common Stock as reported on the NASDAQ Global Select Market for the ten (10) trading days ending on the date that is two (2) Business Days prior to the Closing Date.

The “Upfront Signing Price” is $8.68, which the parties hereto agree is equal to the average of the closing prices of Parent Common Stock as reported on the NASDAQ Global Select Market for the ten (10) trading days ending on the date that is two (2) Business Days prior to the date of execution of this Agreement.

In determining the Applicable Denominator, the amounts of the Upfront Closing Price and Upfront Signing Price will be adjusted, as necessary, to take into account stock splits or reverse stock splits or any dividends of stock or rights with respect to stock that are declared or made to holders of Parent Common Stock in the period between the first measurement date for the Upfront Signing Price and the last measurement date for the Upfront Closing Price.

(iv) “Closing Date Per Share Consideration” means the aggregate of (A) the Closing Date Stock Consideration (consisting of the number of whole shares of Parent Common Stock described in Section 2.1(d)(iii)) divided by the number of Fully Diluted Shares (the “Closing Date Stock Per Share Consideration”) and (B) the Closing Date Cash Consideration divided by the number of Fully Diluted Shares (the “Closing Date Cash Per Share Consideration”).

(v) “Fully Diluted Shares” means (i) the aggregate number of shares of Company Common Stock (other than shares to be canceled in accordance with Section 2.1(a)),

outstanding immediately prior to the Effective Time plus (ii) the number of shares of Company Common Stock issuable upon conversion of all shares of Company Preferred Stock outstanding immediately prior to the Effective Time plus (iii) the number of shares of Company Common Stock issuable upon any exercise of any options or warrants or other rights that gives the holder thereof the right to purchase shares of Company Common Stock that are outstanding immediately prior to the Effective Time plus (iv) the number of shares of Company Common Stock that are issuable upon conversion of all shares of Company Preferred Stock that are issuable upon any exercise of any options or warrants or other rights that give the holder thereof the right to purchase shares of Company Preferred Stock that are outstanding immediately prior to the Effective Time.

(vi) “Indebtedness” means any and all amounts that would be required to be set forth as a liability on a balance sheet prepared in accordance with GAAP (as defined in Section 3.1(d)) as of the Closing Date, including (a) all obligations for borrowed money, (b) any reimbursement obligations in respect of letters of credit, surety bonds or obligations in respect of bankers acceptances, whether or not matured, (c) all obligations to pay the deferred purchase price of property or services, including trade accounts payable and accrued commercial or trade liabilities, (d) all indebtedness created or arising under any conditional sale or other title retention agreement with respect to property acquired (even though the rights and remedies of the seller or lender under such agreement in the event of default are limited to repossession or sale of such property), (e) all capital lease obligations; (f) all unpaid fees and expenses of financial advisors, brokers, attorneys, accountants, consultants and other advisors, including all such fees incurred by Company or for which Company is responsible, relating to this Agreement and the transaction contemplated hereby, regardless of when incurred including any legal expenses incurred after the Closing to assist Company Shareholders in remitting Certificates to the Exchange Agent, completing lost certificate affidavits, etc.; (g) all employment-related taxes that are payable by the Company with respect to the payment of any Merger Consideration to the holders of Company Options; (h) all Taxes that are or may become owing by the Company (exclusive of any reserve for deferred Taxes established to reflect timing differences between book and Tax income) as a result of the operations of the Company prior to the Effective Time regardless of whether or not accrued and (i) in the event that Parent prepares and files a Form S-4 pursuant to Section 4.20, 50% of all of the reasonable costs and expenses, including attorneys’ fees and expenses, of Parent incurred after delivery of the S-4 Notice in preparing, filing and causing the Form S-4 to be declared effective but in any event no more than $50,000; but excluding from the definition of “Indebtedness” total current liabilities of the Company incurred in the ordinary course of business so long as such current liabilities are less than $425,000, but including in the definition of “Indebtedness” any such current liabilities to the extent in excess of $425,000.

(vii) “Liquidation Preference Payment” of a share of Company Preferred Stock shall mean the stated face or redemption amount plus any accrued dividend amounts that, under the terms set forth in Company’s articles of incorporation, are payable in respect of such series of such share of Company Preferred Stock.

(viii) “Closing Date Merger Stock Consideration Value” means the aggregate value of all of the shares of Parent Common Stock issued to the Company Shareholders and Company Option Holders as part of the Closing Date Merger Consideration as

determined by the opening price for such shares as reported on the NASDAQ Global Select Market (or such other exchange on which shares of Parent Common Stock may be traded on the date of issuance) on the date of issuance. The “Closing Date Merger Consideration Value” means the sum of the Closing Date Merger Stock Consideration Value and the aggregate amount of cash issued to the Company Shareholders and Company Option Holders as part of the Closing Date Merger Consideration, which shall include for purposes of the definition of Closing Date Merger Consideration Value all amounts paid with respect to shareholders who assert dissenters rights, payments to holders of Company Preferred Stock and any and all other consideration paid to any Person in connection with the Merger by virtue of such Person’s holdings of shares of Company Capital Stock or options or warrants to acquire shares of Company Capital Stock, exclusive of any amounts considered to be imputed interest with respect to the payment of any Closing Date Merger Consideration.

(e) Potential Adjustment to Closing Date Cash Consideration. In the event that the Closing Date Merger Stock Consideration Value would constitute less than 40% of the Closing Date Merger Consideration Value to be paid and issued to the Company Shareholders and Company Option Holders hereunder before giving effect to this Section 2.1(e), then there shall be a reduction in the amount of cash that comprises the Closing Date Cash Consideration such that, after giving effect to such reduction, the Closing Date Merger Stock Consideration Value equals 40% of the aggregate Closing Date Merger Consideration paid and issued to the Company Shareholders and Company Option Holders hereunder. The amount of any such reduction is referred to herein as the “Closing Date Cash Adjustment Amount”.

(f) Merger Co., First Surviving Corporation and Acquisition Co. Capital Stock. At the Effective Time by virtue of the Reverse Merger, each share of common stock, par value $0.01 per share, of Merger Co. outstanding immediately prior to the Effective Time shall be automatically converted into and become one fully paid and non-assessable share of common stock, par value $0.01 per share, of the First Surviving Corporation. Each certificate evidencing ownership of shares of common stock of Merger Co. shall thereafter evidence ownership of shares of common stock of First Surviving Corporation. At the Second Effective Time by virtue of the Forward Merger, each share of common stock, par value $0.01 per share, of First Surviving Corporation outstanding immediately prior to the Second Effective Time shall be automatically canceled without any consideration or other payment therefore. At the Second Effective Time by virtue of the Forward Merger, each share of common stock, par value $0.01 per share, of Acquisition Co. outstanding immediately prior to the Second Effective Time shall be automatically converted into and become one fully paid and non-assessable share of common stock, par value $0.01 per share, of the Surviving Corporation. Each certificate evidencing ownership of shares of common stock of Acquisition Co. shall thereafter evidence ownership of shares of common stock of Surviving Corporation.

2.2 Options and Warrants. All options, warrants, or other rights to purchase shares of Company Capital Stock (each, a “Company Option”) which are outstanding immediately prior to the Effective Time shall not be assumed by Parent, First Surviving Corporation or Surviving Corporation and shall therefore become, pursuant to their respective terms, fully vested and exercisable prior to the Effective Time. Holders of Company Options shall be given the opportunity to exercise their Company Options effective prior to the Effective Time. All Company Options that remain unexercised and outstanding as of the Effective Time shall be

terminated and canceled as of the Effective Time and converted into, and represent only, the right to receive from Parent, for each share of Company Common Stock that is issuable upon full exercise of the Company Option (including, for this purpose, the number of shares of Company Common Stock that are issuable upon conversion of all shares of Company Preferred Stock that are issuable upon any exercise of a Company Option) the Closing Date Per Share Consideration and the FDA Milestone Per Share Consideration all on the terms set forth in this Article II; provided, however, that (i) there shall be deducted from the aggregate Closing Date Cash Per Share Consideration payable with respect to each Company Option, an amount equal to (A) the Closing Cash Percentage multiplied by the exercise per share price of the applicable Company Option multiplied by (B) the total number of shares of Company Common Stock issuable upon full exercise of the Company Option and (ii) there shall be deducted from the aggregate Closing Date Stock Per Share Consideration payable with respect to each Company Option a number of shares of Parent Common Stock that have a value (based on the Applicable Denominator) equal to (C) the Closing Stock Percentage multiplied by the exercise per share price of the applicable Company Option multiplied by (D) the total number of shares of Company Common Stock issuable upon full exercise of the Company Option, provided further, however, that if the product of clause (A) and (B) in clause (i) is greater than the aggregate Closing Date Cash Per Share Consideration payable with respect to a Company Option, then a number of shares of Parent Common Stock that have a value (based on the Applicable Denominator) equal to the amount of the excess of the product of (A) and (B) over the aggregate Closing Date Cash Per Share Consideration payable with respect to such Company Option shall also be deducted from the aggregate Closing Date Stock Per Share Consideration payable with respect to such Company Option. Following the Effective Time, no holder of Company Options, or any participant in or beneficiary of any of the Company Benefit Plans, shall have any right to acquire or receive any equity securities or other interests in the First Surviving Corporation, Parent, Surviving Corporation or their respective Subsidiaries, or any other consideration.

2.3 FDA Milestone Payments.

(a) FDA Milestone Consideration Generally.

(i) FDA Milestone Consideration. Parent shall pay, or cause the Exchange Agent to pay, the FDA Milestone Consideration (as defined in Section 2.3(b)(ii)) to the holders of Company Common Stock entitled to such payment pursuant to Section 2.1(c) and holders of Company Options entitled to such payment pursuant to Section 2.2 (the “Milestone Payees”) if, and only if, the Surviving Corporation receives the PMA Letter (as defined in Section 2.3(b)(vii)) on or before December 31, 2012, in which case the FDA Milestone Consideration will become payable as set forth in this Section 2.3.

(ii) Payout of FDA Milestone Consideration. The amount of FDA Milestone Consideration that each Milestone Payee shall be entitled to receive hereunder, if any, shall be an amount equal to the FDA Milestone Per Share Consideration (as defined in Section 2.3(b)(iii)) for each share of Company Common Stock held, or subject to a Company Option held, by each Milestone Payee at the Effective Time.

(iii) FDA Milestone Consideration as Merger Consideration. The parties acknowledge and agree that the achievement by the Surviving Corporation of certain

regulatory approvals is a material factor in determining the valuation of Company by Parent. The FDA Milestone Consideration payable pursuant to this Section 2.3 does not constitute payment for services, but rather constitutes part of the merger consideration payable by Parent in connection with the Merger (the “Merger Consideration”) and shall be treated as such for all purposes, including for tax purposes.

(iv) FDA Milestone Consideration Not Transferable. No Milestone Payee may sell, exchange, transfer or otherwise dispose of his, her or its right to receive any portion of the FDA Milestone Consideration, other than with the consent of the Parent or by the laws of descent and distribution or succession. Any transfer in violation of this Section 2.3(a)(iv) shall be null and void and shall not be recognized by Parent or the Surviving Corporation.

(b) Definitions. For purposes of this Agreement:

(i) “Milestone Cash Consideration” means an amount payable in cash equal to (A) the FDA Milestone Consideration less (B) the product of (x) the number of shares that comprise the Milestone Stock Consideration multiplied by (y) the Deemed FDA Milestone Price less (C) any amount payable to Asante Partners with respect to the FDA Milestone Consideration as set forth in the waiver and release referred to in Section 5.2(i) less (D) any Milestone Cash Adjustment Amount.

(ii) “FDA Milestone Consideration” means $75,000,000, subject to reduction as provided in Section 2.3(d), less any reduction as provided in Section 7.3.

(iii) “FDA Milestone Per Share Consideration” means the aggregate of (A) the Milestone Stock Consideration (consisting of the number of whole shares of Parent Common Stock described in Section 2.3(b)(iv)) divided by the number of Fully Diluted Shares and (B) the Milestone Cash Consideration divided by the number of Fully Diluted Shares.

(iv) “Milestone Stock Consideration” means that number of whole shares of Parent Common Stock equal to the quotient of (A) an amount equal to the Milestone Stock Percentage multiplied by the FDA Milestone Consideration, divided by (B) the greater of (i) the average of the closing prices of Company Common Stock as reported on the NASDAQ Global Select Market for the ten (10) trading days ending on the date that is two (2) Business Days prior to the Milestone Achievement Date (the “Actual FDA Milestone Price”) or (ii) two dollars ($2.00) (the greater of such prices, the “Deemed FDA Milestone Price”), payable in validly issued, fully paid and non-assessable shares of Parent Common Stock. In determining the Deemed FDA Milestone Payment, the amount of two dollars ($2.00) will be adjusted, as necessary, to take into account stock splits or reverse stock splits or any dividends of stock or rights with respect to stock that are declared or made to holders of Parent Common Stock in the period between the last measurement date for the Upfront Signing Price and the last measurement date for the Actual FDA Milestone Price.

(v) “Milestone Stock Percentage” means such percentage as is selected by Parent in its sole discretion subject to the following parameters: (A) such percentage must be between (1) a percentage equal to 80% minus the Closing Stock Percentage and (2) 70%

(inclusive) and (B) if the Actual FDA Milestone Price is equal to or greater than 80% of the Upfront Signing Price, then such percentage must be at least equal to 100% minus the Closing Stock Percentage; provided, however, that in no event can the Milestone Stock Percentage be a percentage that would result in the aggregate number of shares of Parent Common Stock issued to Company Shareholders and Company Option Holders as part of the Merger Consideration to exceed a number that would require the approval of Parent’s stockholders under NASDAQ Market Place Rule 5635 (or any successor rule). In comparing the Actual FDA Milestone Price with the Upfront Signing Price, the amounts will be adjusted, as necessary, to take into account any stock splits or reverse stock splits or any dividend of stock or rights with respect to stock that are declared or made to holders of Parent Common Stock in the period between the first measurement date for the Upfront Signing Price and the last measurement date for the Actual FDA Milestone Price.

(vi) “Merger Stock Consideration Value” means the aggregate value of all of the shares of Parent Common Stock issued to Company Shareholders and Company Option Holders as part of the Merger Consideration as determined by the opening price for such shares as reported on the NASDAQ Global Select Market (or such other exchange on which shares of Parent Common Stock may be traded at the time of issuance) on the date of issuance. “Merger Consideration Value” means the sum of Merger Stock Consideration Value and the amount of cash issued to Company Shareholders and Company Option Holders as part of the Merger Consideration, which shall include for purposes of the definition of Merger Consideration Value all amounts paid with respect to shareholders who assert dissenters rights, payments to holders of Company Preferred Stock and any and all other consideration paid to any Person in connection with the Merger by virtue of such Person’s holdings of shares of Company Capital Stock or options or warrants to acquire shares of Company Capital Stock, exclusive of any amounts considered to be imputed interest with respect to the payment of any FDA Milestone Consideration.

(vii) “PMA Letter” shall mean a letter issued by the United States Food and Drug Administration (“FDA”) which grants clearance or premarket approval for the sale of the Pipeline device in the United States with an indication to treat any subset of intracranial aneurysms, provided that such letter does not impose material restrictions that severely diminish the long term commercial viability of the Pipeline device in the United States, it being understood that none of the following conditions contained in the letter will be deemed to severely diminish the long term commercial viability of the Pipeline device in the United States: (a) the standard conditions (Conditions of Approval) found in all medical device premarket approval and 510(k) clearance letters, as the case may be, issued by the FDA, (b) warnings, cautions, precautions and contraindications that are customary or reasonable given the nature and purpose of the Pipeline device that don’t otherwise, individually or in the aggregate, severely diminish the long term commercial viability of the Pipeline device in the United States, (c) a requirement that a post approval study be conducted on the Pipeline device, (d) a requirement that physicians who will be working with the Pipeline device receive reasonable training with respect to the device, or (e) a requirement that only physicians with expertise in neurovascular procedures use the device. In the event that the FDA issues a letter which does not satisfy the definition of PMA Letter above, then the obligations of the parties under this Agreement to continue to attempt to obtain the PMA Letter shall continue in accordance with the terms of this Agreement.

(c) Potential Adjustment to Milestone Cash Consideration. In the event that the Merger Stock Consideration Value would constitute less than 40% of the aggregate Merger Consideration Value to be paid and issued to the Company Shareholders and Company Option Holders hereunder before giving effect to this Section 2.3(c), then there shall be a reduction in the amount of cash that comprises the Milestone Cash Consideration such that, after giving effect to such reduction, the Merger Stock Consideration Value equals 40% of the aggregate Merger Consideration paid and issued to the Company Shareholders and Company Option Holders hereunder. The amount of any such reduction is referred to herein as the “Milestone Cash Adjustment Amount”.

(d) Adjustments to FDA Milestone Consideration.

(i) If the PMA Letter is issued by the FDA prior to October 1, 2011, the Milestone Payees shall be entitled to the entire FDA Milestone Consideration, which payment shall be distributed as provided in Section 2.3(e) hereof.

(ii) If the PMA Letter is issued by the FDA on or after October 1, 2011 but on or before December 31, 2012, the FDA Milestone Consideration shall be reduced by $3,750,000 per month commencing on October 1, 2011 and calculated pro-rata on a daily basis, which net amount shall be distributed as provided in Section 2.3(e) hereof.

(iii) If the PMA Letter is not issued by the FDA on or before December 31, 2012, no FDA Milestone Consideration shall be payable and will be deemed forfeited and retained permanently by Parent.

(e) FDA Milestone Consideration Distributions.

(i) If the FDA issues the PMA Letter to the Surviving Corporation on or before December 31, 2012, Parent shall, within 15 days following the date on which the FDA issues the PMA Letter (i.e., the date of the PMA Letter) (the “Milestone Achievement Date”), either (A) pay, or cause the Exchange Agent to pay, and distribute to each Milestone Payee in respect of each share of Company Common Stock held or subject to a Company Option held, by such Milestone Payee at the Effective Time, the FDA Milestone Per Share Consideration, or (B) if there is a setoff pursuant to Section 7.3 or a deferment pursuant to Section 2.3(e)(ii), (I) deliver a notice to the Shareholder Representative specifying (1) the amount of FDA Milestone Consideration due and payable, (2) the amount of the offset pursuant to Section 7.3 or the amount of the deferment pursuant to Section 2.3(e)(ii) and a reasonably detailed explanation of any such offset or deferment, and (3) the net aggregate amount of FDA Milestone Consideration, if any, to be distributed to the Milestone Payees with respect to such notice (such notice an “FDA Milestone Notice”), and (II) pay, or cause the Exchange Agent to pay, and distribute to each Milestone Payee in respect of each share of Company Common Stock held, or subject to a Company Option held, by such Milestone Payee at the Effective Time, the FDA Milestone Per Share Consideration payable as set forth in such FDA Milestone Notice, if any.

(ii) Parent’s obligation to pay the Milestone Cash Consideration as described herein is subject to the following conditions: (A) as of the Milestone Achievement Date, Parent has a cash and cash equivalents balance of at least $75,000,000 (the “Deferral Cash

Threshold”); (B) such payment would not cause an “event of default” or otherwise cause Parent to become in material default under any of its credit facilities with a balance owing in excess of $3,000,000; and (C) the Board of Directors of Parent reasonably determines, based on a written analyses provided by a nationally recognized investment banking firm after giving the Shareholder Representative the opportunity to consult with the investment banking firm performing such analyses, that such payment would not be viewed as materially adverse to its business. The Deferral Cash Threshold shall be reduced in an amount equal to the aggregate of (a) the purchase price of any acquisition of another entity (including any acquisition of another entity via a purchase of assets) undertaken by Parent, or any of its affiliates (including without limitation the Surviving Corporation), including without limitation by means of a merger, reorganization, share exchange, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction or any purchase or sale of, or tender or exchange offer for, voting securities that, if consummated, would result in Parent, and/or any of its affiliates (including without limitation the Surviving Corporation), beneficially owning securities representing 15% or more of the total voting power of another entity, or the sale, license or disposition of any material portion of the assets of another entity to Parent, or any of its affiliates (including without limitation the Surviving Corporation); (b) any distributions by Parent, or any of its affiliates (including without limitation the Surviving Corporation), to holders of its securities (including debt securities) or prepayment by Parent, or any of its affiliates (including without limitation the Surviving Corporation), of any note, bond, debt security, indebtedness for borrowed money or any capitalized lease obligation; and (c) any extraordinary capital expenditures by Parent that are not made to accommodate planned growth, replace existing equipment or fixtures or in relation to the business of the Surviving Corporation; in any of the cases described in (a), (b) and (c) only to the extent that such amounts individually exceed $3,000,000 or in the aggregate exceed $5,000,000 and are undertaken during the period from the Closing Date until the earlier of (A) the Milestone Achievement Date and (B) December 31, 2012. In the event all of the foregoing conditions are not satisfied at the time the FDA Milestone Consideration is payable, Parent may at its option defer up to $30,000,000 of the Milestone Cash Consideration until the earlier of (1) the first date that any of the conditions set forth above is satisfied or (2) twelve (12) months following the Milestone Achievement Date. Any amounts so deferred shall accrue interest at a rate of 8.0% per annum.

2.4 Exchange Agent; Exchange of Certificates.

(a) Prior to the Effective Time, Parent shall designate a bank or trust company reasonably acceptable to Company (the “Exchange Agent”) for the purpose of exchanging certificates which, immediately prior to the Effective Time, represented shares of Company Capital Stock (the “Company Certificates”), and Company Options for the Liquidation Preference Payment or Per Share Merger Consideration, as the same may become payable from time to time pursuant to the provisions of this Article II, pursuant to an agreement between Parent and the Exchange Agent. The fees and expenses of the Exchange Agent shall be paid by Parent.

(b) Deposit of Merger Consideration; Adjustment to Closing Date Cash Consideration. On or before the Closing Date, Parent shall deposit, or shall cause to be deposited, with the Exchange Agent, for the benefit of the shareholders of Company as of the Effective Time (the “Company Shareholders”) and holders of Company Options as of the

Effective Time (the “Company Option Holders”) (A) cash in an amount sufficient to pay to all Company Shareholders and Company Option Holders the aggregate Closing Date Cash Consideration (or any Liquidation Preference Payment payable in cash) together with any cash to be paid in lieu of fractional shares with respect to the Closing Date Stock Consideration pursuant to Section 2.8 and (B) certificates or, at Parent’s option, evidence of shares in book entry form, representing shares of Parent Common Stock that comprise the Closing Date Stock Consideration (or any Liquidation Preference Payment payable in stock) (the “Parent Certificates”). Notwithstanding the foregoing, however, the Closing Date Cash Consideration and the Closing Date Stock Consideration to be deposited with the Exchange Agent under and paid to the Company Shareholders and Company Option Holders following the Effective Time as provided herein will be calculated based on the Estimated Closing Cash and the Estimated Indebtedness, and the Closing Date Cash Consideration to be deposited with the Exchange Agent following the Effective Time will be subject to true up as provided in Section 2.5. Such Parent Certificates and such cash so deposited, together with any dividends or distributions with respect thereto, are hereinafter referred to as the “Exchange Fund”.

(c) Exchange Procedures. Parent will cause the Exchange Agent to send to each Company Shareholder or Company Option Holder within five Business Days after the Effective Time (i) 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 and Company may reasonably specify), and (ii) instructions to effect the surrender of the Company Certificates in exchange for, or for the Company Option Holders to receive payment of, the Liquidation Preference Payment or Per Share Merger Consideration, as applicable. Until surrendered as contemplated by this Section 2.4(c), each Company Certificate, or until the Exchange Agent receives a duly completed and signed letter of transmittal, each Company Option, shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Liquidation Preference Payment or the Per Share Merger Consideration, as the same may become payable from time to time pursuant to the provisions of this Article II. Except pursuant to Section 2.3(e)(ii), no interest will be paid or will accrue on any cash payable to holders of Company Certificates or Company Options under the provisions of this Article II.

(d) Transfers. In the event that a transfer of ownership of shares of Company Capital Stock is not registered in the stock transfer books or ledger of Company, or if any Parent Certificate for the portion of the Liquidation Preference Payment or the Per Share Merger Consideration payable in 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 to the issuance thereof that the Company Certificates so surrendered shall be properly endorsed or otherwise be in proper form for transfer and that the Person requesting such exchange shall have paid to the Exchange Agent any transfer or other taxes required as a result of the issuance of a Parent Certificate in any name other than that of the registered holder of such shares of Company Capital Stock or Company Option, or establish to the satisfaction of the Exchange Agent that such tax has been paid or is not payable. For purposes of this Agreement, “Person” means an individual, a corporation, a limited liability company, a partnership, an association, a trust or any other entity or organization, including a government or political subdivision or any agency or instrumentality thereof.

(e) Tax Withholding. Each of the Exchange Agent, the Surviving Corporation and Parent shall be entitled to deduct and withhold from the Liquidation Preference Payment or Per Share Merger Consideration otherwise payable to any Company Shareholder or Company Option Holder, such amounts as the Exchange Agent, the Surviving Corporation or Parent is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of United States federal, state or local tax law or any other non-U.S. tax law or any other applicable legal requirement. To the extent that amounts are so withheld by the Exchange Agent, the Surviving Corporation or Parent, such amounts withheld from the Liquidation Preference Payment or Per Share Merger Consideration and other such amounts payable under Section 2.4(e) shall be treated for all purposes of this Agreement as having been received by the Company Shareholder or Company Option Holder in respect of which such deduction and withholding was made by the Exchange Agent, the Surviving Corporation or Parent. Any amounts withheld pursuant to this provision will be promptly paid to the relevant federal, state or local or other non-U.S. tax authority, and the withholding party shall provide evidence of such payment to the Shareholder Representative upon request.

(f) Distributions with Respect to Unexchanged Shares. No dividends or other distributions with respect to Parent Common Stock with a record date on or after the Effective Time, or that are payable to the holders of record thereof who become such on or after the Effective Time, shall be paid to the holder of any unsurrendered Company Certificate or to the holder of any Company Option that has not submitted a duly completed and signed letter of transmittal for payment therefor until those certificates are surrendered or until duly completed and signed letters of transmittal are submitted as provided in this Article II. All such dividends, other distributions and cash in lieu of fractional shares of Parent Common Stock which are to be paid in respect of the shares of Parent Common Stock to be received upon surrender of the Company Certificate or upon receipt of such letter of transmittal shall be paid by Parent to the Exchange Agent and shall be included in the Exchange Fund, in each case until the surrender of such Company Certificate or receipt of such letter of transmittal in accordance with this Article II. Subject to the effect of applicable escheat or similar Applicable Laws and Applicable Laws with respect to the withholding of taxes, following surrender of any such certificate there shall be paid to the holder of the Parent Certificate representing whole shares of Parent Common Stock issued in exchange therefor, without interest (i) at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time previously paid with respect to such whole shares of Parent Common Stock and the amount of any cash payable in lieu of a fractional share of Parent Common Stock to which such holder is entitled pursuant to Section 2.8 and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such whole shares of Parent Common Stock.

(g) No Further Rights in Company Capital Stock. All Parent Common Stock issued and cash paid upon surrender of a Company Certificate or upon delivery of a duly completed and signed letter of transmittal with respect to a Company Option in accordance with the terms of this Article II and any cash paid pursuant to Section 2.4(f) or Section 2.8 shall be deemed to have been issued in full satisfaction of all rights pertaining to the Company Capital Stock or Company Options formerly represented by such certificate or option.

(h) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of the Company Certificates or Company Options for one year after the Effective Time shall be delivered to Parent upon demand, and any holders of Company Capital Stock or Company Options who have not theretofore complied with this Article II shall thereafter look only to Parent for payment of Liquidation Preference Payment or Per Share Merger Consideration payable with respect to their shares of Company Capital Stock or Company Options pursuant to this Article II and any dividends or distributions with respect to shares of Parent Common Stock to which they are entitled pursuant to Section 2.4(f).

(i) Closing of Transfer Books. At the Effective Time, the stock transfer books of Company shall be closed, and there shall be no further registration of transfers of shares of Company Capital Stock that were outstanding immediately prior to the Effective Time thereafter on the transfer books of the Surviving Corporation. From and after the Effective Time, the holders of Company Certificates representing shares of Company Capital Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such shares, except as otherwise provided in this Agreement or by Applicable Law. On or after the Effective Time, any Company Certificates presented to the Exchange Agent or Parent for any reason shall be canceled and converted in accordance with the terms of this Article II.

(j) Investment of Exchange Fund. The Exchange Agent shall invest all cash included in the Exchange Fund as directed by Parent. Any interest and other income resulting from such investments shall be paid to Parent.

If any Company Certificates has been lost, stolen or destroyed, the Exchange Agent will be authorized to pay the Liquidation Preference Payment or Per Share Merger Consideration, as applicable and as the same may become payable from time to time pursuant to this Article II, attributable to any such Company Certificate upon receipt of satisfactory evidence of ownership of the shares of Company Capital Stock represented thereby and of appropriate indemnification. Neither Parent nor the Surviving Corporation will be liable to any Company Shareholder or Company Option Holder for any portion of the Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Applicable Laws.

2.5 Adjustments to Closing Date Merger Consideration.

(a) Estimated Closing Amounts. Company will prepare and deliver to Parent not less than three (3) or more than ten (10) Business Days prior to the anticipated Closing Date, a statement which will set forth a good faith estimate of (i) the amount of cash and cash equivalents held by the Company, as of the anticipated Closing Date (the “Estimated Closing Cash”), and (ii) the Indebtedness of Company as of the anticipated Closing Date (the “Estimated Indebtedness”).

(b) Final Closing Amounts. The Surviving Corporation will prepare and deliver to the Shareholder Representative within 30 days after the Closing Date, a statement (the “Closing Statement”) (i) setting forth (A) the amount of cash and cash equivalents held by Company as of the Closing Date (the “Closing Cash”), and (B) the Indebtedness of Company as

of the Closing Date (the “Closing Indebtedness”), and (ii) setting forth the amount of any required adjustments pursuant to this Section 2.5.

(i) If the Closing Cash is less than the Estimated Closing Cash, there shall be a negative true-up adjustment in an amount equal to the difference between the Closing Cash and the Estimated Closing Cash.

(ii) If the Closing Cash is greater than the Estimated Closing Cash, there shall be a positive true-up adjustment in an amount equal to the difference between the Closing Cash and the Estimated Closing Cash.

(d) Post-Closing Indebtedness Adjustment.

(i) If the Closing Indebtedness is less than the Estimated Indebtedness, there shall be a positive true-up adjustment in an amount equal to the difference between the Closing Indebtedness and the Estimated Indebtedness.

(ii) If the Closing Indebtedness is greater than the Estimated Indebtedness, there shall be a negative true-up adjustment in an amount equal to the difference between the Closing Indebtedness and the Estimated Indebtedness.

(e) Review by Shareholder Representative. The Shareholder Representative shall have 30 days after the receipt of the Closing Statement to review the Closing Statement and all work papers and other documents generated or reviewed by the Surviving Corporation in connection with the preparation of the Closing Statement, and all books and records of the Surviving Corporation related to the Closing Statement (the “Statement Review Period”). If, within the Statement Review Period, the Shareholder Representative disputes any item(s) on the Closing Statement, the Shareholder Representative shall give Parent written notice of such disagreement specifically identifying the item(s) and amount(s) in dispute and the basis for such dispute (the “Dispute Notice”). The parties shall use reasonable efforts to reach agreement with respect to such disputed items within 10 days following the delivery of the Dispute Notice, or such longer period as may be agreed upon in writing by the parties (the “Resolution Period”). Any item(s) on or omitted from the Closing Statement not specifically identified in writing as a disputed item before the end of the Statement Review Period shall be deemed to have been accepted by the Shareholder Representative and shall not be subject to any further dispute, review or change. If the parties fail to resolve any such disputes with respect to the Closing Statement within the Resolution Period, the disputed item(s) shall be resolved and, as a result thereof, the amount of the Closing Cash or Closing Indebtedness, as the case may be, shall be definitely and finally determined using the Financial Issue Resolution Process set forth in Section 2.5(f).

(f) Financial Issue Resolution Process. Disputes between Parent and the Shareholder Representative relating to accounting matters under Section 2.5 of this Agreement that cannot be resolved by negotiation in accordance with Section 2.5(e) shall be definitely and finally determined by a nationally or regionally recognized firm of independent public accountants agreed upon by both Parent and the Shareholder Representative (the “Accounting

Firm”), who shall act as experts as to accounting matters and not as arbitrators and whose determination shall be final and binding strictly with respect to matters dependent only on accounting issues. Parent and the Shareholder Representative shall select, by mutual agreement, the Accounting Firm if the stated accounting firm is unwilling to serve, and the Accounting Firm shall have agreed in writing to serve in such capacity pursuant to the terms herein described, within 10 days following the end of the applicable resolution period described in Section 2.5(e). The resolution of any disputed item(s) as to accounting matters and the determination of the Closing Cash or the Closing Indebtedness, as the case may be, shall be completed by the Accounting Firm within 30 days following the time the dispute is submitted to it. The Accounting Firm’s determination of the Closing Cash and Closing Indebtedness shall be completed in a manner consistent with GAAP as applied by Company in accordance with past practices. The fees and expenses associated with the Accounting Firm’s determination shall be allocated between Parent and Surviving Corporation, on the one hand, and the Company Shareholders, on the other hand, based on the percentage which the portion of the contested amount not awarded of such party bears to the amount actually contested by such party.

(g) Payment of True Up Amount. After the amount of the Closing Cash and Closing Indebtedness has been finally determined in accordance with Section 2.5(e) or Section 2.5(f), there shall be one true-up adjustment made based on the net of all of the adjustments contemplated by subsections (c) and (d) under Section 2.5. If such net adjustment is a positive amount (the “Additional Consideration”), Parent shall pay such Additional Consideration, which amount shall be made in all cash, into the account in which the Exchange Fund is maintained and thereafter such amount shall be considered part of the Exchange Fund. If such net adjustment is a negative amount (the “Negative Adjustment”), Parent shall be entitled to indemnification pursuant to Section 7.2 in the amount of the Negative Adjustment, less the amount of any payments received by Parent for the Negative Adjustment, in whole or in part, pursuant to any other contractual arrangement for payment of the Negative Adjustment, in whole or in part, to Parent (the “Negative Adjustment Shortfall”). Any payment by Parent into the account in which the Exchange Fund is maintained shall be made within five Business Days following agreement on or final determination of such amount. After such payment is made, the Shareholder Representative and Parent shall cause the Exchange Agent to pay any amount in the Exchange Fund to the Company Shareholders and Company Option Holders entitled to such amounts pursuant to this Article II. Any expenses of the Accounting Firm that are to be borne by the Company Shareholders shall be satisfied by indemnification pursuant to Section 7.2.

2.6 Intentionally Omitted.

2.7 Intentionally Omitted.

2.8 No Fractional Shares. Notwithstanding any provision herein to the contrary, no certificates representing less than one share of Parent Common Stock shall be issued in exchange for shares of Company Capital Stock or Company Options upon the surrender for exchange of a Company Certificate or upon the delivery of a letter of transmittal with respect to a Company Option. In lieu of any such fractional share, each holder of shares of Company Capital Stock or Company Options who would otherwise have been entitled to a fraction of a share of Parent Common Stock upon surrender of a Company Certificate for exchange (or in the case of a lost, stolen or destroyed certificate, upon delivery of an affidavit in the manner provided in Section

2.4(k)) or upon delivery of a letter of transmittal with respect to a Company Option shall be paid upon such surrender or delivery (and after taking into account and aggregating shares of Company Capital Stock or Company Options represented by all Company Certificates surrendered by or Company Options held by such holder) cash (without interest) in an amount equal to the product obtained by multiplying (a) the fractional share interest to which such holder (after taking into account and aggregating all shares of Company Capital Stock or Company Options represented by all Company Certificates surrendered by or Company Options held by such holder) would otherwise be entitled by (b) the Applicable Denominator (in the case of the Closing Date Per Share Consideration) or the Deemed FDA Milestone Price in the case of the FDA Milestone Per Share Consideration.

2.9 Dissenting Shares. Notwithstanding any provision of this Agreement to the contrary, shares of Company Capital Stock that are issued and outstanding immediately prior to the Effective Time and that are held by a holder of such shares of Company Capital Stock who properly exercises appraisal rights with respect thereto in accordance with CCC (such shares, the “Dissenting Shares”) shall not be converted into or represent the right to receive the consideration provided for above, and the holder of such Dissenting Shares will be entitled only to such rights as are granted by the CCC unless and until such holder fails to perfect or effectively withdraws or loses such holder’s right to appraisal and payment under the CCC. Company shall give prompt notice to Parent of any demands received by Company for appraisals of shares of Company Capital Stock. Parent shall have the right to control all negotiations and proceedings with respect to demands for appraisal under the CCC. Company shall not, except with the prior written consent of Parent which shall not be unreasonably withheld, conditioned or delayed, make any payment with respect to any demands for appraisal or offer to settle or settle any such demands.

2.10 Adjustments. If at any time during the period between the date of this Agreement and the Effective Time, any change in the outstanding shares of capital stock of Parent or Company shall occur as a result of any reclassification, recapitalization, stock split (including a reverse stock split) or combination, exchange or readjustment of shares, or any stock dividend or stock distribution with a record date during such period, the Merger Consideration, and any other items similarly dependent on the outstanding shares of capital stock of Parent or Company, as the case may be, shall be equitably adjusted; provided, however, that nothing contained herein shall be deemed to permit any action that Parent is otherwise prohibited from taking pursuant to this Agreement.

2.11 Shareholder Representative.

(a) Immediately prior to the Effective Time, each Company Shareholder and Company Option Holder hereby irrevocably constitutes and appoints CMT SR, Inc. as her, his or its Shareholder Representative as the true and lawful agent and attorney-in-fact of such Company Shareholder and/or Company Option Holder with full powers of substitution to act in the name, place and stead of such Company Shareholder and/or Company Option Holder with respect to the performance, and exercise of any rights and obligations, on behalf of such Company Shareholder and/or Company Option Holder under the terms and provisions of this Agreement, as the same may be from time to time amended, and to do or refrain from doing all such further acts and things, and to execute all such documents on such Company Shareholder’s and/or

4.10 Public Announcements. Parent, Merger Co., Acquisition Co. and Company shall use reasonable best efforts (i) to develop a joint communications plan, (ii) to ensure that all press releases and other public statements with respect to the transactions contemplated hereby shall be consistent with such joint communications plan, and (iii) except in respect of any announcement required by Applicable Law or by obligations pursuant to any listing agreement with or rules of Nasdaq in which it is impracticable to consult with each other as contemplated by this clause (iii), to consult with each other before issuing any press release or, to the extent practical, otherwise making any public statement with respect to this Agreement or the transactions contemplated hereby. In addition to the foregoing, except to the extent disclosed in or consistent with the Company Shareholder Materials in accordance with the provisions of Section 4.7, no party shall issue any press release or otherwise make any public statement or disclosure concerning the other parties or the other parties’ business, financial condition or results of operations without the consent of such other parties, which consent shall not be unreasonably withheld or delayed.

4.11 Form S-3 Resale Registration Statement; Registration Procedures. Unless Parent has provided the S-4 Notice to Company under Section 4.20:

(a) Parent will use (A) best efforts to file a resale registration statement on Form S-3 (the “Registration Statement”) with the SEC not later than five (5) days after the Closing Date and (B) reasonable best efforts to file a Registration Statement no later than thirty (30) days after the Milestone Achievement Date, in each case covering the resale of the shares of Parent Common Stock issued in consideration of the Merger (for the purposes of this Section 4.11, the “Registrable Securities”), in the case of (A) above, with respect to the resale of the shares issued as Closing Date Stock Consideration, and in the case of (B) above, with respect to the resale of the shares, if any, issued as Milestone Stock Consideration. In connection with (A) and (B) above, Parent will use its reasonable best efforts to cause such Registration Statement to become effective as soon as possible and to remain effective as provided herein, provided, however, that in either case before filing the Registration Statement, Parent will

furnish or otherwise make available to the Shareholder Representative’s counsel at least two days prior to filing with the SEC copies of all such documents proposed to be filed in connection with the Registrable Securities registered thereby and keep the Shareholder Representative reasonably apprised of the status of such Registration Statement.

(b) Parent shall use its commercially reasonable efforts to prepare and file with the SEC such amendments and supplements to the Registration Statement as may be necessary to keep the Registration Statement effective until six months from the date the shares registered thereunder were first issued.

(c) Parent shall furnish to each holder of Registrable Securities such number of copies, without charge, of such Registration Statement, each amendment and supplement thereto, and prospectus included therein, all exhibits and other documents filed therewith and such other documents as such Holder may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Holder.

(d) As a condition precedent to registering Registrable Securities, Parent may require each Holder as to which any registration is being effected to furnish Parent with such information regarding such Person and pertinent to the disclosure requirements relating to the registration and the distribution of such securities as Parent may from time to time reasonably request in writing. Each such Holder shall promptly notify Parent in writing of any changes in the information set forth in the Registration Statement after it is prepared regarding the Holder. For the purposes of this Section 4.11, “a Holder” or “the Holders” refers solely to a holder or holders of Registrable Securities as of the Closing Date or as of the Milestone Achievement Date, as applicable.

(e) Parent may, by two days prior written notice to the Holders (each, a “Blackout Notice”), (i) delay the filing of the Registration Statement or a request for acceleration of the effective date or (ii) suspend the Registration Statement after effectiveness and require that the Holders immediately cease sales of shares pursuant to the Registration Statement, in the event that (A) Parent is engaged in any activity or transaction or preparations or negotiations for any activity or transaction that Parent desires to keep confidential for business reasons, if Parent determines in good faith that the public disclosure requirements imposed on Parent under the Securities Act in connection with the Registration Statement would require at that time disclosure of such activity, transaction, preparations or negotiations and such disclosure could result in imminent and material harm to Parent or (B) any other event occurs that makes any statement of a material fact made in the Registration Statement, including any document incorporated by reference therein, untrue or that requires the making of any additions or changes in the Registration Statement in order to make the statements therein not misleading. If Parent suspends the Registration Statement and requires the Holders to cease sales of shares pursuant to this Section 4.11(e), Parent shall, immediately 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 give written notice to all Holders authorizing them to resume sales pursuant to the Registration Statement. If as a result thereof 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 the notice to Holders given pursuant to this Section 4.11(e), and the Holders shall make no offers or sales of shares pursuant

to the Registration Statement other than by means of such revised prospectus. Parent need not specify the nature of the event giving rise to any delay or suspension in any notice to Holders and the Holders agree to treat and keep the existence of such delay or suspension, as the case may be, confidential. Only two Blackout Notices may be delivered in any 12 month period, with a duration of not more than 30 days in the aggregate.

4.12 Stock Exchange Listing. Parent shall use reasonable best efforts to cause the Closing Date Stock Consideration to be approved for listing on the Nasdaq Stock Market prior to the Closing Date. Parent shall use reasonable best efforts to cause the Milestone Stock Consideration to be approved for listing on the Nasdaq Stock Market, subject to official notice of issuance, prior to the dates of its issuance.

4.13 Supporting FDA Approval Process. From and after the Effective Time, the Surviving Corporation will manage its overall ongoing business as it determines reasonably necessary to pursue and obtain the issuance of the PMA Letter. From and after the Closing Date until the earlier of the Milestone Achievement Date or December 31, 2012, Parent will not make any material changes to the Pipeline business of the Surviving Corporation that it reasonably believes would adversely affect the issuance of the PMA Letter and specifically agrees (i) that the existing manufacturing and operations of the Surviving Corporation relating to Pipeline will be maintained as reasonably necessary to facilitate a favorable FDA inspection in support of getting the PMA Letter and (ii) not to terminate, or cause the Surviving Corporation to terminate, the employment of, or materially change the terms of employment of ▇▇▇▇▇▇ ▇. ▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇ and ▇▇▇▇ ▇▇; provided, however, that Parent will be permitted to terminate, or permit the Surviving Corporation to terminate, the employment of any such individuals for reasons that would constitute “cause” under the employment agreements by and between the Surviving Corporation and the executives of the Surviving Corporation. Notwithstanding the foregoing, however, Parent shall not be required to provide funding to the Surviving Corporation in excess of $6,000,000 in any calendar year (which amount will be pro-rated for the calendar year 2009 based on when the Closing occurs).

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

4.15 Tax Free Qualification. Notwithstanding anything to the contrary in this Agreement, each of Parent, Merger Co., Acquisition Co. and Surviving Corporation shall use its reasonable best efforts to ensure the Merger qualifies as a reorganization within the meaning of Section 368(a) of the Code.

4.16 Employees and Employee Benefit Plan Matters.

(a) Parent will compensate, or cause its appropriate affiliates to compensate, each individual employed by Company at the Closing (an “Employee”) for the period beginning on the Closing Date and ending on December 31, 2009 so long as such Employee is employed by Parent or its affiliates (i) at a base wage or base salary rate, and any applicable variable pay rate

(e.g., shift differential pay), which shall not be less than that provided to the Employee by Company immediately prior to the Closing Date; and (ii) with employee benefit plans and similar programs (including for this purpose a holiday schedule), which may include any of the Company Benefit Plans, which are of all the same material types as, and which on an economic basis in the aggregate are substantially comparable to, the comparable Company Benefit Plans as in effect immediately prior to the Closing Date except for equity compensation plans.

(b) Nothing in this Agreement shall be interpreted as limiting the power of Parent and its affiliates, including the Surviving Corporation, to amend or terminate any Parent welfare or employee benefit plan or to discontinue the employment of any given Employee, subject to applicable legal requirements and any other applicable provisions of this Agreement.

4.17 Parent Changes. During the period between the date of this Agreement and the Effective Time, except as contemplated by this Agreement, Parent shall not undertake during such period (i) a merger, reorganization, stock exchange, consolidation, business combination or recapitalization if such transaction results in the Parent Common Stock no longer being publicly traded or (ii) a liquidation or dissolution of Parent.

4.18 Section 280G Matters.

(a) Within five days after the date hereof, the Company will deliver a document setting forth in reasonable detail a list of all persons who may be “disqualified individuals” (as defined in Section 280G(c) of the Code) and who may be receiving payments or benefits in connection with the Merger (under this Agreement or any other contract, plan or arrangement with the Company or otherwise, including severance payments and acceleration of vesting or repurchase right lapse, or benefits under options or restricted stock). Such document shall be accompanied by a worksheet or memorandum from the Company’s counsel demonstrating the extent (if any) to which such payments, vesting or benefits constituting “excess parachute payments” within the meaning of Section 280G of the Code will or could be made to such disqualified individuals. If for any reason it will reasonably appear that a disqualified individual will receive an excess parachute payment, then the balance of this Section 4.18 will apply, in addition to any other rights and remedies Parent may have.

(b) Prior to the Effective Time of Merger, the Company will submit to, and use all reasonable efforts to obtain, a shareholder vote or written consent approving the right of any “disqualified individual” to receive or retain any and all payments that could be deemed “parachute payments” under Section 280G of the Code and the related waiver by such “disqualified individual” described in clause (b) below, on the following terms and conditions interpreted in a manner which complies with Section 280G of the Code and all applicable final, proposed or temporary regulations thereunder: (a) such payments so submitted for approval will be computed without reduction for any amounts which could otherwise be treated as excludable, reasonable compensation for services rendered before or after the Effective Time of the Merger under Section 280G(b)(4) of the Code; such payments will be calculated assuming all options and restricted stock are ultimately settled at the maximum FDA Milestone Consideration; such payments will be calculated including maximum severance potentially payable; such payments will not include post-merger base pay, performance bonus, company-paid employee benefits or other compensatory amounts paid or available for performance of post-merger services; (b) the

shareholder approval will be timely solicited in form and substance and pursuant to such disclosure as will be sufficient to satisfy the shareholder approval requirements for the small business exemption of Section 280G(b)(5) of the Code, including requirements that such disqualified individual waive in advance the right to such payment if the requisite shareholder approval is not obtained, and such payments will be separately approved within the meaning of such regulations; and (c) for such approval to be effective as to any such payment, 75% or more of the voting power of the Company will have approved such payment without counting as outstanding or permitting to vote (except as contemplated by Treasury Regulations Section 1.280G-1, Q&A-7(b)(4)) any stock (i) actually owned or constructively owned under Section 318(a) of the Code by or for such disqualified individual, or (ii) as to which the owner of such stock is considered under Section 318(a) of the Code to own any part of the stock owned directly or indirectly by or for such disqualified individual.

4.19 Merger Consideration Distributions. On the day before the anticipated Closing Date, Company will deliver a complete and correct list, in excel spreadsheet format, of (a) Company Shareholders as of the Closing Date, identifying each Company Shareholder by name, address, and the number of shares owned, the aggregate Closing Date Stock Per Share Consideration and Closing Date Cash Per Share Consideration issuable or payable to such shareholder, and share ownership information, including Company Certificate numbers, the number of whole shares represented by each Company Certificate, and the date of issuance for each Company Certificate, and (b) Company Option Holders as of the Closing Date, identifying each Company Option Holder by name, address, and the number of whole shares of Company Common Stock that are issuable upon full exercise of the Company Option (including the number of whole shares of Company Common Stock that are issuable upon conversion of all shares of Company Preferred Stock that are issuable upon exercise of a Company Option), the exercise price of each Company Option, and the aggregate Closing Date Stock Per Share Consideration and Closing Date Cash Per Share Consideration issuable or payable to such Company Option Holder; which such list will supersede and replace the similar list delivered to Parent as promptly as practicable after the date hereof and will be delivered by Parent to the Exchange Agent for use in distributing the Closing Date Stock Per Share Consideration and Closing Date Cash Per Share Consideration.

4.20 Preparation and Filing of Form S-4. In the event that the condition set forth in Section 5.2(f) has not been satisfied on or prior to July 10, 2009, then Parent may elect to have the provisions of this Section 4.20 apply by delivering written notice (the “S-4 Notice”) of such election to the Company. If Parent delivers such S-4 Notice:

(a) The Company will promptly cease any and all actions that constitute directly or indirectly engaging or participating in any activities that reasonably could be deemed to have the effect of soliciting Company Shareholders and Company Option Holders with respect to the offer or issuance of the shares of Parent Common Stock to be received by the Company Shareholders and Company Option Holders in the Merger or the approval of the Company Shareholders of the Merger until the Form S-4 has been declared effective by the Securities and Exchange Commission (SEC).

(b) After an appropriate period of time as determined by Parent upon advice of counsel so as not to cause Parent to be in violation of any federal or state securities laws or

adversely affect Parent’s ability to register the shares of Parent Common Stock to be issued in connection with the Merger not to exceed 30 days, Parent will prepare and file with the SEC a Registration Statement on Form S-4 in connection with the issuance of shares of Parent Common Stock in the Merger (as may be amended or supplemented from time to time, the “Form S-4”). The Form S-4 shall include (i) a prospectus for the issuance of shares of Parent Common Stock in the Merger and (ii) the Company Shareholder Materials (as may be amended as necessary or appropriate to reflect the applicability of the provisions of this Section 4.20 and the fact that a meeting of the Company Shareholders shall take place in lieu of the Proposed Written Consent) (as may be amended or supplemented from time to time, the “Proxy Statement-Prospectus”). The Proxy Statement-Prospectus will include the Company Board Recommendation in favor of this Agreement and the Merger and the conclusion of the Company Board that the terms and conditions of the Merger are in the best interests of the Company Shareholders. Company shall, and shall cause its respective representatives to, fully cooperate with Parent hereto and its respective representatives in the preparation of the Form S-4 and the Proxy Statement-Prospectus, and shall furnish Parent with all information concerning it and its affiliates as the Parent may deem reasonably necessary or advisable in connection with the preparation of the Form S-4 and the Proxy Statement-Prospectus, and any amendment or supplement thereto, and Parent shall provide the Company with a reasonable opportunity to review and comment thereon before it is filed with the SEC.

(c) The Company shall use reasonable best efforts in accordance with Applicable Law and Company’s Articles of Incorporation and Bylaws to duly call, give notice of, convene and hold, as promptly as practicable under the Company’s Bylaws and the CCC, a meeting of its shareholders (the “Company Shareholder Meeting”) for the purpose of considering and voting upon the approval of the Company Shareholder Proposal. Company shall use its reasonable best efforts to solicit from the Company Shareholders proxies in favor of the Company Shareholder Proposal and to secure the Required Company Shareholder Vote. Company shall use its reasonable best efforts to ensure that all proxies solicited in connection with the Company Shareholder Meeting are solicited in compliance with the CCC, Company’s Articles of Incorporation and Bylaws, and all other Applicable Laws. Company shall submit the Company Shareholder Proposal to the Company Shareholders at the Company Shareholder Meeting for the purpose of acting upon such proposal, whether or not the Company Board’s fiduciary duties require the Company Board to change its Company Board Recommendation to the Company Shareholders.

(d) As promptly as practicable after the Form S-4 is declared effective by the SEC, and regardless of whether or not the Company Board’s fiduciary duties require the Company Board to change its Company Board Recommendation to the Company Shareholders, Company shall cause the Proxy Statement-Prospectus to be mailed to each of its shareholders and shall thereafter use its commercially reasonable efforts to obtain the Required Company Shareholder Vote as soon as practicable.

Termination and Amendment

6.1 Termination. This Agreement may be terminated at any time prior to the Effective Time, whether before or after the Required Company Shareholder Vote has been obtained, by mutual consent of Parent, Merger Co., Acquisition Co. and Company in a written instrument:

(a) by either Parent or Company, upon written notice to the other party, if a Governmental Entity of competent jurisdiction that must grant a Requisite Regulatory Approval has denied approval of the Merger and such denial has become final and non-appealable; or any Governmental Entity of competent jurisdiction shall have issued an order, decree or ruling or taken any other action permanently restraining, enjoining or otherwise prohibiting the Merger, and such order, decree, ruling or other action has become final and non-appealable; provided, however, that the right to terminate this Agreement under this Section 6.1(a) shall not be available to any party whose failure to comply with Section 4.3 or any other provision of this Agreement has been a proximate cause of, or resulted in, such action;

(b) by either Parent or Company if the Merger shall have not been consummated on or before the date that is three (3) months from the date of this Agreement (the “Termination Date”); provided, however, that if the condition set forth in Section 5.2(f) has not been satisfied on or prior to July 10, 2009, then neither Parent or Company may terminate this Agreement under this Section 6.1(b) until the date that is 60 days after the date that the Form S-4 has been declared effective by the SEC; provided, however, that the right to terminate this Agreement pursuant to this Section 6.1(b) shall not be available to any party hereto whose action or failure to fulfill any covenant or obligation under this Agreement has been a proximate cause of or resulted in any of the conditions to the consummation of the transactions contemplated hereby set forth in Article V having failed to be satisfied or fulfilled on or prior to the Termination Date, and such action or failure to fulfill any covenant or obligation constitutes a material breach of this Agreement;

(d) by either Parent or Company, upon written notice to the other party, if there shall have been a breach by the other party of any of the covenants or agreements or any of the representations or warranties set forth in this Agreement on the part of such other party, which breach, either individually or in the aggregate, would result in, if occurring or continuing on the Closing Date, the failure of the condition set forth in Section 5.2(a) or (b) or Section 5.3(a) or (b), as the case may be, and which breach has not been cured within thirty (30) days following written notice thereof to the breaching party or, by its nature or timing, cannot be cured within such time period; provided, however, that such cure period will be extended for such longer period (not to exceed the Termination Date) during which the breaching party exercises commercially reasonable efforts to cure.

6.2 Effect of Termination. In the event of termination of this Agreement by either Company or Parent as provided in Section 6.1, this Agreement shall forthwith become void, and there shall be no liability or obligation on the part of Parent or Company or their respective

officers or directors, except with respect to Section 4.8 (Fees and Expenses), this Section 6.2 (Effect of Termination) and Article VIII (General Provisions), which shall survive such termination as provided therein and except that no party shall be relieved or released from any liabilities or damages arising out of its willful and material breach of this Agreement.

6.3 Amendment. This Agreement may be amended by the parties, at any time before or after approval of the matters presented in connection with this Agreement by the Company Shareholders but, after any such approval, no amendment shall be made which by Applicable Law requires further approval by such shareholders without such further approval. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

6.4 Extension; Waiver. At any time prior to the Effective Time, the parties may, to the extent permitted by Applicable Law, (i) extend the time for the performance of any of the obligations or other acts of the other parties, (ii) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto, and (iii) waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party. The failure of a party to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights. No single or partial exercise of any right, remedy, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. Any waiver shall be effective only in the specific instance and for the specific purpose for which given and shall not constitute a waiver to any subsequent or other exercise of any right, remedy, power or privilege hereunder.

For purposes of this Agreement, the term “Losses” means any and all losses, damages, liabilities, deficiencies, claims, diminution in value, interest, awards, judgments, penalties, costs and expenses (including attorneys’ fees, costs and other out-of-pocket expenses incurred in investigating, preparing or defending the foregoing) asserted against, incurred, sustained or suffered by an Indemnitee.

(d) Indemnification Reserve. For purposes of this Agreement, the term “Indemnification Reserve” means a portion of the FDA Milestone Consideration equal to the lower of (I) fifteen million dollars ($15,000,000) and (II) the FDA Milestone Consideration. In the event that no FDA Milestone Consideration is payable, the Indemnification Reserve shall be zero.

7.3 Satisfaction of Indemnifiable Losses After the Effective Time. Parent’s right to indemnification after the Effective Time under Section 7.2(a) shall be satisfied solely through a set-off by Parent of any indemnifiable Losses it is entitled to recover under Section 7.2(a) against any payment of FDA Milestone Consideration owed to Milestone Payees pursuant to Section 2.3. Parent shall also be entitled to withhold from any payment of FDA Milestone Consideration, an amount equal to the amount of indemnifiable Losses for which Parent believes

in good faith it is entitled to indemnification under Section 7.2(a), in respect of which the Shareholder Representative has been provided notice, which withheld amount shall be applied against indemnifiable Losses as and when such indemnifiable Losses are determined in accordance with this Article VII. In no event shall Parent be entitled to reduce the value of the FDA Milestone Consideration that is set-off against indemnifiable Losses under this Section 7.3 by more than the amount of the Indemnification Reserve, with set-off being done in both cash and shares of Parent Common Stock in the same ratio as such cash and shares comprise the Milestone Cash Consideration and the Milestone Stock Consideration, respectively (with the value of any share of Parent Common Stock determined by using the Deemed FDA Milestone Price). The Indemnitees shall provide the Shareholder Representative with notice of any set-off by Parent for any indemnifiable Losses, which will set forth the basis for and amount of such indemnifiable Loss and right to set-off (an “Indemnification Set-off Notice”). The Shareholder Representative shall have 60 days after the receipt of an Indemnification Set-off Notice to review the Indemnification Set-off Notice and assess the validity of Indemnitees’ claim for set-off against the FDA Milestone Consideration (the “Set-off Review Period”). If, within the Set-off Review Period, the Shareholder Representative disputes any claim for indemnification and set-off by Parent against the FDA Milestone Consideration set forth in the Indemnification Set-off Notice, the Shareholder Representative shall give Parent written notice of such disagreement specifically identifying the indemnifiable Losses and set-off amounts in dispute and the basis for such dispute (the “Set-off Dispute Notice”). The parties shall use reasonable efforts to reach agreement with respect to such disputed items within 30 days following the delivery of the Set-off Dispute Notice, or such longer period as may be agreed upon in writing by the parties (the “Set-off Resolution Period”). Any indemnifiable Loss and set-off not specifically identified in writing as a disputed item before the end of the Set-off Review Period shall be deemed to have been accepted by the Shareholder Representative and shall not be subject to any further dispute, review or change. If the parties fail to resolve any such disputes with respect to an indemnifiable Loss and set-off right set forth in an Indemnification Set-off Notice within the Set-off Resolution Period, Parent shall have the right to exercise such set-off and the Shareholder Representative shall have the right to seek remedy in law in accordance with the provisions of this Agreement.

7.4 Third-Party Claims. With respect to any third-party claim that Parent believes, in good faith, may result in a demand by it for indemnification hereunder, the Shareholder Representative shall be entitled to participate, at his or her sole cost and expense, in any defense of such claim. Notwithstanding the immediately preceding sentence, Parent shall conduct and control such defense, but shall not settle any such claim without the consent of the Shareholder Representative, such consent not to be unreasonably withheld; provided, however, that, if such Shareholder Representative consent is so obtained, neither the Shareholder Representative nor any other Company Shareholder shall have any power or authority to object under any provision of this Article VII to the amount of any demand by Parent for indemnification (up to the amount of the Indemnification Reserve with respect to all Indemnifiable Losses) with respect to such settlement.

7.5 Remedies. Prior to the Effective Time, Parent shall have the right to seek any remedy in law or equity, including an action for breach of contract, in lieu of or in addition to any remedies provided in this Article VII. Furthermore, the Company understands that if the Company fails to fulfill the Company’s obligations under this Agreement to consummate the transactions contemplated hereby the damages to Parent would be very difficult to determine.

Therefore, in addition to any other rights or remedies available to the Company at law, in equity, or by statute, the parties agree that Parent shall be entitled to specific enforcement with respect to the Company’s obligations to consummate the transactions contemplated hereby and to comply with the Company’s covenants related thereto, including, without limitation, Sections 4.6 and 4.7.

7.6 Waiver of Defenses. To the maximum extent permitted by Applicable Law, each Indemnifying Party waives any claim or defense that the indemnification rights provided for in this Article VII are unenforceable under any provision of Applicable Law.

7.7 Treatment of Indemnification Payments. All indemnification payments made to Parent shall be, and shall be treated as, an adjustment to the Merger Consideration.

This Agreement may be executed by facsimile signature (including signatures in Adobe PDF or similar format).

8.4 Entire Agreement; No Third Party Beneficiaries.

8.5 Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware (without giving effect to choice of law principles thereof).

8.6 Severability. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability and, unless the effect of such invalidity or unenforceability would prevent the parties from realizing the major portion of the economic benefits of the Merger that they currently anticipate obtaining therefrom, shall not render invalid or unenforceable the remaining terms and provisions of this Agreement or affect the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable.

8.7 Assignment. Neither this Agreement nor any of the rights, interests or obligations of the parties hereunder shall be assigned by any of the parties hereto (whether by operation of law or otherwise) without the prior written consent of the other parties, and any attempt to make any such assignment without such consent shall be null and void.

Each party hereto further irrevocably consents to the service of process out of any of the aforementioned applicable courts in any such suit, action or other proceeding set forth in clause (i) or (ii), as applicable, by the mailing of copies thereof by mail to such party at its notice address as determined in accordance with Section 8.1 hereof, such service of process to be effective upon acknowledgment of receipt of such registered mail; provided that nothing in this Section 8.8 shall affect the right of any party to serve legal process in any other manner permitted by law. The consent to jurisdiction set forth in this Section 8.8 shall not constitute a general consent to service of process in the State of Minnesota or the State of California and shall have no effect for any purpose except as provided in this Section. The parties hereto agree that a final judgment in any such suit, action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

8.9 Enforcement. The parties 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 on a timely basis or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in any court identified in the Section above without the necessity to post a bond or other security, this being in addition to any other remedy to which they are entitled at law or in equity.

8.10 WAIVER OF JURY TRIAL. EACH OF THE PARTIES HEREBY WAIVES TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY, IN ANY MATTERS (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH, THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

8.11 Conflict Waiver; Legal Files.

(a) Each party to this Agreement acknowledges that ▇▇▇▇▇▇▇▇▇ Will & ▇▇▇▇▇ LLP (“▇▇▇▇▇▇▇▇▇”) has acted as legal counsel for the Company in connection with this Agreement and the Merger and other transactions contemplated hereby and thereby (collectively, the “Contemplated Transactions”) and not as counsel for any shareholder, director or employee of the Company as of prior to the Closing. Each party agrees that following the Closing, ▇▇▇▇▇▇▇▇▇ may represent any or all of such shareholders, directors or employees, and/or the Shareholder Representative in their capacity as such and not as a representative of the Surviving Corporation, with respect to the enforcement of and other matters relating to this Agreement and

the Contemplated Transactions, including if the Surviving Corporation is an adverse party thereto. Each party to this Agreement hereby (1) acknowledges that they have had an opportunity to ask for and have obtained information relevant to such representation and they have had the opportunity to obtain advice of independent counsel related so such representation and the matters set forth in this Section 8.11; (2) gives its informed consent to ▇▇▇▇▇▇▇▇▇’▇ representation of the Company in connection with this Agreement and the Contemplated Transactions prior to the Effective Time; and (3) gives its informed consent to ▇▇▇▇▇▇▇▇▇’▇ representation of the Company’s shareholders, directors or employees, and/or the Shareholder Representative in their capacity as such and not as a representative of the Surviving Corporation, with respect to the enforcement of and other matters relating to this Agreement and the Contemplated Transactions.

(b) The legal files of the Company for the period through the Effective Time shall become the property of the Surviving Corporation on and after the Closing. Notwithstanding the foregoing, the parties acknowledge that the Company’s legal files relating to the drafting and negotiation of this Agreement and to the Contemplated Transactions (“Company Transaction Legal Files”) contain confidential and attorney-client privileged material with respect to the matters set forth herein which may prejudice certain parties, including without limitation the Shareholder Representative, Company employees and Company Shareholders and Company Option Holders, in the event such parties attempt to enforce their rights and obligations hereunder. Accordingly, Parent and the Surviving Corporation agree that the Company Transaction Legal Files shall remain in the custody of the Shareholder Representative following the Closing. The parties will cooperate in good faith to preserve attorney-client privilege with respect to the Company Transaction Legal Files. Parent, the Surviving Corporation and their respective agents hereby waive any right to claim loss of attorney-client privilege in connection with the custody of the Company Transaction Legal Files described herein. The Shareholder Representative agrees to provide Parent, the Surviving Corporation and their respective agents with access to the Company Transaction Legal Files as necessary in connection with matters other than disputes among the parties hereto relating to this Agreement and to the Contemplated Transactions.
