During the last five years, neither Covidien DE nor, to the best of its knowledge, any of its directors or executive officers has been (1) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (2) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding has been or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

On May 7, 2009, Covidien Group, Covidien DE and VNUS entered into an Agreement and Plan of Merger (the “Merger Agreement”) pursuant to which Covidien DE will commence a tender offer (the “Offer”) to acquire (i) all of the issued and outstanding common stock, $0.001 par value per share, of VNUS (the “Shares”), at $29.00 per share, net to the seller, in cash for each outstanding Share (the “Offer Price”) less any applicable withholding taxes and without payment of interest, and, subject to the satisfaction or waiver of the conditions set forth in the Offer and the Merger Agreement, after consummation of the Offer, Covidien DE will merge with and into VNUS (the “Merger”), whereupon Covidien DE’s separate corporate existence will cease and VNUS will continue as the surviving corporation and as a wholly owned subsidiary of Covidien Group.

As an inducement to enter into the Merger Agreement, and in consideration thereof, Covidien Group and Covidien DE entered into Tender and Voting Agreements (each, a “Tender and Voting Agreement”), dated as of the date of the Merger Agreement, with each of Brian Farley, W. James Fitzsimmons, Lori M. Robson, Edward W. Unkart, Michael J. Coyle, Gregory T. Schiffman, Peter Osborne, Kirti Kamdar, Mohan Sancheti, Mark Saxton, William A. Franklin, Jr., Donald Todd, Guido Smeets and Scott Murcray (each, a “Stockholder” and, collectively, the “Stockholders”). Pursuant to the Tender and Voting Agreements, each Stockholder has severally agreed to tender in the Offer any Shares owned of record by Stockholder or for which Stockholder has sole dispositive power, and not to withdraw such tender unless the Offer shall have been terminated in accordance with its terms. As of May 13, 2009, the Tender and Voting Agreements covered 209,091 Shares, options to purchase 810,765 Shares and 338,545 Shares underlying restricted stock units, totaling approximately 7.8% of the Shares then outstanding on a fully diluted basis (assuming exercise of all options and full vesting of all restricted stock units held by the Stockholders).

Pursuant to the Tender and Voting Agreements, each Stockholder has irrevocably appointed Covidien Group as proxy for the Stockholder to vote all Shares as to which such Stockholder has voting power and in Stockholder’s name, place and stead, at any annual, special or other meeting or action of the shareholders of VNUS, as applicable, or at any adjournment thereof, whether before or after the time at which Covidien DE first accepts any Shares for payment pursuant to the Offer, solely for the adoption of the Merger Agreement. Additionally, each Stockholder has granted Covidien Group an irrevocable option (the “Purchase Option”) to purchase all right, title and interest of Stockholder in and to Stockholder’s Shares and securities exchangeable, exercisable or convertible into Shares, with a price per share equal to the Offer Price. Covidien Group may exercise the Purchase Option in whole, but not in part, if, but only if, (a) Covidien DE has acquired Shares pursuant to the Offer and (b) Stockholder has failed to tender into the Offer any Shares or has withdrawn the tender of any Shares into the Offer in breach of Stockholder’s respective Tender and Voting Agreement. Covidien Group may exercise the Purchase Option at any time within the 60 days following the date when such Purchase Option becomes exercisable.

Shared dispositive power with respect to the Shares owned by the Stockholders may be deemed to have been acquired through execution of the Tender and Voting Agreements. Covidien Group has not expended any funds in connection with the execution of the Tender and Voting Agreements, except for the transaction expenses (funded from Covidien Group’s working capital) otherwise to be incurred in connection with the Offer and the Merger.

Covidien Group and Covidien DE estimate that, if Covidien DE acquires all of the Shares (on a fully-diluted basis) pursuant to the Offer, the total cash amount required to purchase such shares and to cover estimated fees and expenses will be approximately U.S. $530 million. Covidien Group or one of its affiliates will provide all funding required by Covidien DE in connection with the Offer from cash on hand.

A copy of the Merger Agreement is attached as Exhibit 2 to this Schedule 13D. A form of the Tender and Voting Agreement is included as Annex II to the Merger Agreement. References to, and descriptions of, the Merger Agreement and the Tender and Voting Agreements as set forth above in this Item 3 are qualified in their entirety by reference to the copies of the Merger Agreement and the form of Tender and Voting Agreement included as Exhibit 2 to this Schedule 13D and which are incorporated herein in their entirety by this reference. The information set forth and/or incorporated by reference in Item 6 is hereby incorporated by reference into this Item 3.

The information set forth and/or incorporated by reference in Items 2 and 3 is hereby incorporated by reference into this Item 4.

The purpose of entering into the Merger Agreement and the Tender and Voting Agreements, and the purpose of the Offer, is to enable Covidien Group and Covidien DE to acquire control of, and ultimately the entire equity interest in, VNUS. The Offer is conditioned upon, among other things, (a) there being validly tendered and not withdrawn prior to the expiration date that number of Shares which represents a majority of the issued and outstanding Shares then outstanding on a fully diluted basis (which, for purposes of such calculation, includes all Shares underlying restricted stock units and Shares that VNUS may be required to issue pursuant to options that are outstanding at that date, regardless of the exercise price, the vesting schedule or other terms and conditions thereof), and (b) the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, having expired or been terminated. Subject to the terms of the Merger Agreement and applicable law, Covidien DE reserves the right to withdraw the Offer and to not take up and pay for any Shares deposited in the Offer unless each of the conditions to the Offer is satisfied or, where permitted, waived by VNUS at or prior to the expiration of the Offer.

Pursuant to the Merger Agreement, VNUS has granted Covidien DE an irrevocable option (the “Top-Up Option”) to purchase at a price per share equal to the Offer Price up to a number of newly issued Shares (the “Top-Up Shares”) equal to the lowest number of Shares that, when added to the number of Shares directly or indirectly owned by Covidien DE or Covidien Group at the time of exercise of the Top-Up Option, will constitute one share more than 90% of the Shares outstanding immediately after the issuance of the Top-Up Shares (determined on a “fully diluted basis” (which, for purposes of such calculation, includes all Shares underlying restricted stock units and Shares that VNUS may be required to issue pursuant to options that are outstanding at that date, regardless of the conversion or exercise price, the vesting schedule or other terms and conditions thereof)). However, the Top-Up Option is not exercisable for a number of Shares in excess of the Shares authorized and unissued at the time of exercise of the Top-Up Option, and the Top-Up Option may not be exercised unless, following the time Covidien DE accepts the Shares in the Offer or after a subsequent offering period, 80% or more of the Shares will be directly or indirectly owned by Covidien DE or Covidien Group. Covidien DE may exercise the Top-Up Option once at any time following the time at which Covidien DE first accepts any Shares for payment pursuant to the Offer. The purpose of this provision is to facilitate a short-form merger following completion of the Offer.

If the conditions of the Offer are satisfied or waived and Covidien DE takes up and pays for any Shares

validly deposited under the Offer, Covidien DE intends to acquire any Shares not deposited under the Offer through a merger under Delaware General Corporation Law, or through a subsequent offering period, in each case for cash consideration per Share equal to the Offer Price. The exact timing and details of any such transaction will depend upon a number of factors, including the number of Shares acquired pursuant to the Offer. Although Covidien DE intends to effect such a transaction generally on the terms described herein, it is possible that, as a result of delays in Covidien DE’s ability to effect such a transaction, information subsequently obtained by the Reporting Persons, changes in general economic or market conditions or in the business of VNUS, or other currently unforeseen circumstances, such a transaction may be delayed or abandoned or may be proposed on different terms.

The Merger Agreement provides that, upon the payment by Covidien DE for any Shares accepted by Covidien DE for payment pursuant to the Offer, which Shares represent at least a majority of the issued and outstanding Shares pursuant to the Offer, Covidien Group will be entitled to designate a number of directors on the VNUS board of directors as will give Covidien Group representation on the VNUS board of directors equal to at least that number of directors, rounded up to the next whole number, which is the product of (i) the total number of directors on the VNUS board of directors (giving effect to the directors elected pursuant to this sentence) multiplied by (ii) the percentage that (I) such number of Shares so accepted for payment and paid for by Covidien DE plus the number of Shares otherwise owned by Covidien Group, Covidien DE or any other subsidiary of Covidien Group bears to (II) the number of such Shares outstanding, and VNUS will, at such time, cause Covidien Group’s designees to be so elected. At such time, VNUS will, upon Covidien Group’s request, also cause persons elected or designated by Covidien Group to constitute the same percentage (rounded up to the next whole number) as is on the VNUS board of directors of (i) each committee of the VNUS board of directors, (ii) each board of directors (or similar body) of each of the VNUS subsidiaries, and (iii) each committee (or similar body) of each such board, in each case only to the extent permitted by applicable law or the rules of any stock exchange on which Shares are listed. Subject to applicable law, VNUS will take all action requested by Covidien Group necessary to effect any such election. In connection with the foregoing, VNUS will promptly, at the option of Covidien DE, either increase the size of the VNUS board of directors or obtain the resignation of such number of its current directors, or both, as is necessary to enable Covidien DE’s designees to be elected or appointed to the VNUS board of directors as provided above.

The Merger Agreement provides that from the period from the date of the Merger Agreement until the earlier of the termination of the Merger Agreement pursuant to its terms or the consummation of the Merger, VNUS will, except to the extent that Covidien Group otherwise consents in writing and except as otherwise expressly provided in the Merger Agreement, carry on its business in the ordinary course, in substantially the same manner as it was conducted prior to signing the Merger Agreement. Without limiting the generality of the foregoing, without the prior written consent of Covidien Group (such consent not to be unreasonably withheld, conditioned or delayed) and except as otherwise specifically provided in, or in furtherance of any action permitted to be taken by, the Merger Agreement, during the period from the date of the Merger Agreement and continuing until the earlier of the termination of the Merger Agreement pursuant to its terms or the consummation of the Merger, VNUS has agreed to (1) except for actions taken in the ordinary course of business consistent with past practices, use its commercially reasonable efforts to preserve intact and keep available the services of present employees of VNUS and its subsidiaries; (2) use commercially reasonable efforts to keep in effect casualty, product liability, workers’ compensation and other insurance policies in coverage amounts substantially similar to those in effect at the date of the Merger Agreement; (3) use commercially reasonable efforts to preserve the business of VNUS, to develop, commercialize and pursue regulatory approvals for its product candidates and products and to advertise, promote and market its products, and use commercially reasonable efforts to keep its properties substantially intact, to preserve its goodwill and business, to maintain all physical properties in such operating condition as will permit the conduct of its business on a basis consistent with past practice; (4) use commercially reasonable efforts to preserve and protect its intellectual property; (5) use commercially reasonable efforts with respect to outstanding options and restricted stock to effectuate the terms of the Merger Agreement; (6) notify and consult with Covidien Group promptly (A) after receipt of any material communication from any governmental entity or inspections of any manufacturing or clinical trial site and before giving any material submission to a governmental entity, and (B) prior to making any material change to a study protocol, adding new trials, making any material change to a manufacturing plan or process, or making a material change to the development timeline for any of its product candidates or programs; (7) advise Covidien Group orally and in writing of any change or event that would reasonably be expected to have a Company Material Adverse Effect (as defined in the Merger Agreement); (8) not

sell or transfer, or mortgage, pledge, lease, license or otherwise encumber any of its assets, including the proprietary rights owned by VNUS, other than sales, transfers, mortgages, pledges, leases, licenses or other encumbrances in the ordinary course of business and in amounts not exceeding, in the aggregate, $250,000; (9) not incur any indebtedness for borrowed money in excess of $250,000 in the aggregate or incur any obligation or liability or enter into any contract or commitment involving potential payments to or by VNUS or any of its subsidiaries, other than in the ordinary course of business consistent with past practice, in an amount aggregating in excess of $500,000; (10) not change the compensation payable to any officer, director, employee, agent or consultant, or enter into any employment, severance, retention or other agreement or arrangement with any officer, director, employee, agent or consultant of VNUS or any of its subsidiaries, or adopt, or increase the benefits (including fringe benefits) under, any employee benefit plan or otherwise, except (A), in each case, as required by law or in accordance with existing agreements disclosed by VNUS in the disclosure schedule and (B), in the case of compensation for employees, agents or consultants who are not officers or directors, in the ordinary course of business consistent with past practice; or make any loans to any of its directors, officers or employees, agents or consultants, or make any change in its existing borrowing or lending arrangements for or on behalf of any such persons pursuant to an employee benefit plan or otherwise; (11) not make any change in the number of shares of its capital stock authorized, issued or outstanding or grant or accelerate the exercisability of any option, warrant or other right to purchase, or convert any obligation into, shares of its capital stock, declare or pay any dividend or other distribution with respect to any shares of its capital stock, sell or transfer any shares of its capital stock, or redeem or otherwise repurchase any shares of its capital stock; provided, however, the foregoing limitations does not apply in connection with (A) the payment (in cash) of any dividends required to made under the Company’s certificate of incorporation, as in effect on the date hereof and (B) the conversion or exercise of convertible securities outstanding on the date of the Merger Agreement, including, without limitation, the issuance of Shares upon the exercise of VNUS stock options; (12) not cause, permit or propose any amendments to the certificate of incorporation or bylaws of VNUS or any of its subsidiaries or elect or appoint any new officers; (13) not make, or permit to be made, any material acquisition, lease, investment, or capital contribution outside the ordinary course of business consistent with past practice; (14) not authorize any single capital expenditure in excess of $250,000 or capital expenditures which in the aggregate exceed $750,000; (15) except as may be required as a result of a change in law or in generally accepted accounting principles, not change any of the accounting practices or principles used by it; (16) not make, revise or amend any material tax election or settle or compromise any material federal, state, local or non-U.S. tax audit or proceeding, change any annual tax accounting period, change any material method of tax accounting, enter into any closing agreement relating to any material tax, file any amended material tax return, prepare or file any material tax return in a manner inconsistent with past practice, surrender any right to claim a material tax refund, or consent to any extension or waiver of the limitations period applicable to any material tax claim or assessment; (17) not commence, settle or compromise any pending or threatened suit, action or claim which (A) is material to the business of VNUS and its subsidiaries, taken as a whole, or otherwise involves the payment by VNUS of more than $500,000 in the aggregate, for all suits, actions or claims (B) would involve restrictions on the business activities of the VNUS or its subsidiaries or (C) would involve the issuance of its securities; (18) not adopt a plan of complete or partial liquidation, dissolution, merger, consolidation, restructuring, recapitalization or other reorganization of VNUS or any of its subsidiaries (other than the Offer and Merger); or take any action to render inapplicable, or to exempt any person from the provisions of the DGCL or any other law that purports to limit or restrict business combinations or the ability to acquire or vote shares of capital stock; (19) not pay, discharge or satisfy any material claims, liabilities or obligations (absolute, accrued, asserted or unasserted, contingent or otherwise), other than the payment, discharge or satisfaction, in the ordinary course of business and consistent with past practice, of liabilities reflected or reserved against in the balance sheet VNUS has submitted to Covidien DE and Covidien Group or incurred in the ordinary course of business since the date of the balance sheet VNUS has submitted to Covidien DE and Covidien Group; (20) not make any loans, advances or capital contributions to, or investments in, any other person (other than to wholly owned subsidiaries of VNUS or customary advances to employees for travel and business expenses in the ordinary course of business);

After Covidien DE purchases the Shares pursuant to the Offer, Covidien Group may appoint its representatives to the VNUS board of directors in proportion to its ownership of the outstanding Shares, as described above. Prior to the effective time of the Merger, VNUS shall cause its Directors, other than the designees of Covidien DE or Covidien Group, to execute and deliver a letter effectuating his or her resignation as a director of VNUS upon the Effective Time

If permitted by applicable law, subsequent to the completion of the Offer and a short-form merger or any subsequent offering period, if necessary, the Reporting Persons intend to delist the Shares from The Nasdaq Global Market.

THIS AGREEMENT AND PLAN OF MERGER (this “Agreement”) dated as of May 7, 2009 is among Covidien Group S.a.r.l. (“Parent”), a Luxembourg company, Covidien Delaware Corp. (“Sub”), a newly-formed Delaware corporation and a direct or indirect wholly-owned subsidiary of Parent, and VNUS Medical Technologies, Inc. (the “Company”), a Delaware corporation.

WHEREAS, Parent and the Board of Directors of each of Sub and the Company has approved the acquisition of the Company by Parent on the terms and conditions set forth in this Agreement;

WHEREAS, in furtherance thereof, it is proposed that Sub commence a cash tender offer (as it may be amended from time to time as permitted by this Agreement, the “Offer”) to acquire all shares of the issued and outstanding common stock, par value $0.001 per share, of the Company (the “Shares”), for $29.00 for each Share, net to the seller in cash (such price, or any such higher price per Share as may be paid in the Offer, referred to herein as the “Offer Price”), without interest;

WHEREAS, the Board of Directors of each of Sub and the Company has approved this Agreement and the transactions contemplated hereby, including the Merger (as defined in Section 1.3(a)) following the Offer in accordance with the Delaware General Corporation Law (“DGCL”) and upon the terms and subject to the conditions set forth herein;

WHEREAS, the Board of Directors of the Company (the “Company Board of Directors”) has determined that the consideration to be paid for each Share in the Offer and the Merger is fair to the holders of such Shares and has resolved to recommend that the holders of Shares accept the Offer and, if necessary, adopt this Agreement and thereby approve the Merger upon the terms and subject to the conditions set forth herein;

WHEREAS, concurrently with the execution and delivery of this Agreement, and as a condition and inducement to Parent entering into this Agreement, certain Company stockholders (the “Principal Stockholders”) have entered into tender and voting agreements, dated as of the date hereof, in substantially the form set forth in Annex II hereof, pursuant to which, among other things, each of the Principal Stockholders has agreed to tender his, her or its Shares to Sub in the Offer (the “Tender and Voting Agreements”); and

WHEREAS, the Company, Parent and Sub desire to make certain representations, warranties, covenants and agreements in connection with the Offer, the Merger and the other transactions contemplated hereby.

NOW, THEREFORE, in consideration of the foregoing and the respective covenants, agreements, representations and warranties set forth herein, the parties agree as follows:

(a) Provided that this Agreement shall not have been terminated in accordance with Section 8.1, Parent shall cause Sub to, and Sub shall, commence (within the meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended (together with the rules and regulations promulgated thereunder, the “Exchange Act”)) the Offer no later than May 18, 2009 (the date on which the Offer is commenced being referred to herein as the “Commencement Date”). The obligations of Sub to accept for payment and to pay for any Shares validly tendered and not withdrawn prior to the expiration of the Offer (as it may be extended in accordance with requirements of this Section 1.1(a)) shall be subject only to the conditions set forth in Annex I hereto (the “Offer Conditions”). Subject to the prior satisfaction or, to the extent permitted, waiver by Parent or Sub of the Offer Conditions, Parent shall cause Sub to, and Sub shall, consummate the Offer in accordance with its terms and accept for payment all Shares validly tendered and not withdrawn pursuant to the Offer and pay the Offer Price in exchange for each such Share promptly following such acceptance in compliance with Rule 14e-1(c) of the Exchange Act (the time at which Sub first accepts any Shares for payment pursuant to the Offer being referred to herein as the “Acceptance Time”). The Offer shall be made by means of an offer to purchase (the “Offer to Purchase”) that contains the terms set forth in this Agreement and the Offer Conditions. Parent expressly reserves the right to waive any of the Offer Conditions, to increase the Offer Price and to make any other changes in the terms of the Offer; provided, however, that Sub shall not, and Parent shall cause Sub not to, without the prior written consent of the Company (such consent to be authorized by the Company Board of Directors or a duly authorized committee thereof), (i) decrease the Offer Price, (ii) change the form of consideration payable in the Offer, (iii) decrease the number of Shares sought in the Offer, (iv) waive or change the Minimum Condition, (v) impose additional conditions to the Offer or amend any of the Offer Conditions so as to broaden the scope of such Offer Condition, (vi) extend the Offer beyond a date that is twenty-one (21) business days after commencement of the Offer or the last extension (in accordance with this Section 1.1), if any, of the Offer, whichever is later (the “Expiration Date”) except as set forth in Sections 1.1(b) and 1.1(c), or (vii) otherwise amend any other term or condition of the Offer in a manner materially adverse to the holders of Shares.

(b) The Offer shall initially be scheduled to expire on the twenty-first (21st) business day following the Commencement Date (calculated as set forth in Rule 14d-1(g)(3) and Rule 14e-1(a) under the Exchange Act). Notwithstanding anything to the contrary contained in this Agreement, but subject to the parties’ respective termination rights set forth in Section 8.1, (i) if, at the time as of which the Offer is scheduled to expire, any Offer Condition is not satisfied and has not been validly waived, then Sub may extend the Offer on one or more occasions, for additional successive periods of up to twenty (20) business days per extension (with the length of such periods to be determined by Parent) until all of the Offer Conditions have been satisfied or, to the extent permitted, validly waived, and (ii), Sub shall extend the Offer for any period required by any rule, regulation or interpretation of the United States Securities and Exchange Commission (“SEC”), or the staff thereof, applicable to the Offer. In addition to the foregoing, Sub also may provide a “subsequent offering period” in accordance with Rule 14d-11 under the Exchange Act if, as of the Expiration Date, all of the Offer Conditions have been satisfied or, to the extent permitted, waived, but there shall not have been validly tendered and not withdrawn pursuant to the Offer that number of Shares necessary to permit the Merger to be effected without a meeting of the Company’s stockholders in accordance with the DGCL.

(c) Subject to the parties’ respective termination rights set forth in Section 8.1, if, at the time as of which the Offer is scheduled to expire, any Offer Condition has not been satisfied or has not been validly waived and there has not been an Adverse Recommendation Change, then, if so requested by the Company by written notice at least two (2) business days prior to the date the Offer is then scheduled to expire, Sub shall extend the Offer for up to two (2) successive periods of ten (10) business days per extension period, until all of the Offer Conditions have been satisfied or, to the extent permitted, validly waived.

(d) On the date of commencement of the Offer, Parent and Sub shall file with the SEC, pursuant to Regulation M-A under the Exchange Act (“Regulation M-A”), a Tender Offer Statement on Schedule TO with respect to the Offer (together with all amendments, supplements and exhibits thereto, the “Schedule TO”). The Schedule TO shall include, as exhibits, the Offer to Purchase and a related form of letter of transmittal and summary advertisement (collectively, together with any amendments and supplements thereto, the “Offer Documents”). Subject to Section 5.2, the Company hereby consents to the inclusion in the Offer Documents of the Company Board Recommendation referred to in Section 3.20(a). Parent and Sub agree to take commercially reasonable steps to cause the Offer Documents to be filed with the SEC and, subject to the Company’s compliance with Section 1.2(c), disseminate the Offer Documents to holders of Shares, in each case as and to the extent required by applicable Law. Parent and Sub, on the one hand, and the Company, on the other hand, agree to promptly correct any information provided by it for use in the Offer Documents if and to the extent that it shall have become false or misleading in any material respect or as otherwise required by Law. Parent and Sub further agree to take all steps necessary to cause the Offer Documents as so corrected to be filed with the SEC and disseminated to holders of Shares, in each case as and to the extent required by applicable Law. The Company shall be given a reasonable opportunity to review and comment on the Schedule TO and any amendment thereto before it is filed with the SEC, and Parent and Sub shall include all additions, deletions or changes thereto suggested by the Company and its legal counsel that Parent reasonably determines to be appropriate. In addition, Parent and Sub agree to provide the Company with any comments, whether written or oral, that Parent, Sub or their counsel may receive from time to time prior to the expiration or termination of the Offer, from the SEC or its staff with respect to the Offer Documents, promptly upon receipt of such comments, and any written or oral responses thereto, and the Company shall have the right to consult with Parent, Sub and their counsel prior to responding to any such comments, either in written or oral form, and Parent and Sub shall incorporate in each response those views and comments of the Company and its legal counsel related thereto that Parent reasonably determines to be appropriate.

(e) Parent shall provide or cause to be provided to Sub as promptly as practicable following the expiration of the Offer and any subsequent offering period, as applicable, all funds necessary to pay for those Shares that have been validly tendered and not withdrawn pursuant to the Offer and that Sub is obligated to accept for payment pursuant to the Offer and permitted to accept for payment under applicable Law.

(a) Subject to Section 5.2 and to any consents or approvals of the Company’s stockholders required under applicable Law, the Company hereby approves of and consents to the Offer, the Merger and the other transactions contemplated hereby.

(b) On the date the Offer is commenced, the Company shall, in a manner that complies with Rule 14d-9 under the Exchange Act, file with the SEC a Tender Offer Solicitation/Recommendation Statement on Schedule 14D-9 (together with all amendments, supplements and exhibits thereto, the “Schedule 14D-9”) which shall, subject to the provisions of Section 5.2, contain the Company Board Recommendation. The Company further agrees to take commercially reasonable steps to cause the Schedule 14D-9 to be filed with the SEC and disseminated to holders of Shares, in each case as and to the extent required by applicable Law. The Company, on the one hand, and Parent and Sub, on the other hand, agree to promptly correct and supplement any information provided by it for use in the Schedule 14D-9 if and to the extent that it shall have become false or misleading in any material respect or as otherwise required by Law. The Company agrees to take all steps necessary to cause the Schedule 14D-9 as so corrected to be filed with the SEC and disseminated to holders of the Shares, in each case as and to the extent required by applicable Law. Parent and Sub shall be given the opportunity to review and comment on the Schedule 14D-9 and any amendment thereto before filing with the SEC, and the Company shall include all additions, deletions or changes thereto suggested by Parent and its legal counsel that the Company reasonably determines to be appropriate. In addition, the Company agrees to provide Parent and Sub any comments, whether written or oral, that the Company or its counsel may receive from time to time from the SEC or its staff with respect to the Schedule 14D-9 promptly after receipt of such comments, and to consult with Parent, Sub and their counsel prior to responding to any such comments, either in written or oral form, and the Company shall incorporate in each response those views and comments of Parent and its legal counsel related thereto that the Company reasonably determines to be appropriate.

(c) The Company shall promptly furnish or cause to be furnished to Parent or Sub mailing labels, security position listings and all available listings and computer files containing the names and addresses of the record holders of the Shares as of a recent date, and of those persons becoming record holders subsequent to such date, and shall promptly furnish Parent or Sub with such information and assistance (including, but not limited to, lists of holders of the Shares, updated periodically, and their addresses, mailing labels and lists of security positions) as Parent or Sub or its agent(s) may reasonably request. Subject to applicable Law, such information shall be held confidential by Parent and Sub under the terms of the Confidentiality and Standstill Agreement, dated February 3, 2009 entered into between Tyco Healthcare Group LP, d/b/a Covidien and the Company (as amended, the “Confidentiality Agreement”). For the avoidance of doubt, the parties agree that the Confidentiality Agreement does not restrict steps to prepare, file or disseminate the Offer Documents and any other documents necessary to consummate the transactions contemplated hereby.

(a) Subject to the terms and conditions of this Agreement, at the Effective Time (as defined in Section 1.4), the Company and Sub shall consummate a merger (the “Merger”) in accordance with the DGCL pursuant to which (i) Sub will be merged with and into the Company and the separate corporate existence of Sub will thereupon cease; (ii) the Company

will be the successor or surviving corporation in the Merger and will continue to be governed by the Laws of the State of Delaware; (iii) the separate corporate existence of the Company with all its rights, privileges, immunities, powers and franchises will continue unaffected by the Merger; and (iv) the Company will succeed to and assume all the rights and obligations of Sub. The corporation surviving the Merger is sometimes hereinafter referred to as the “Surviving Corporation.” The Merger shall have the effects set forth in the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the property, rights, privileges, powers and franchises of the Company and Sub shall be vested in the Surviving Corporation, and all debts, liabilities and duties of the Company and Sub shall become the debts, liabilities and duties of the Surviving Corporation.

(b) At the Effective Time, the certificate of incorporation of the Company shall, by virtue of the Merger, be amended and restated in its entirety to read in the form of Annex III and, as so amended, shall be the certificate of incorporation of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law.

(c) At the Effective Time, and without any further action on the part of the Company and Sub, the bylaws of the Company shall be amended and restated in their entirety to be identical to the bylaws of Sub as in effect immediately prior to the Effective Time (except that such bylaws shall be amended to reflect that the name of the Surviving Corporation shall be VNUS Medical Technologies, Inc.), and, as so amended, shall be the bylaws of the Surviving Corporation until thereafter changed or amended as provided by the DGCL, the certificate of incorporation of the Surviving Corporation and such bylaws.

1.4. Effective Time. Parent, Sub and the Company shall cause an appropriate certificate of merger complying with Section 251 of the DGCL or an appropriate certificate of ownership and merger complying with Section 253 of the DGCL, as applicable (the “Certificate of Merger”), to be executed and filed on the Closing Date (as defined in Section 1.5) (or on such other date as Parent and the Company may agree) with the Secretary of State of the State of Delaware as provided in the DGCL. The Merger shall become effective on the time and date on which the Certificate of Merger has been duly filed with the Secretary of State of the State of Delaware or such later time and date as is specified in the Certificate of Merger, such time hereinafter referred to as the “Effective Time.”

1.5. Closing. The closing of the Merger (the “Closing”) will take place at 9:00 a.m. (Boston time) on a date to be specified by the parties, such date to be no later than the second (2nd) business day after satisfaction or, to the extent permitted, waiver of all of the conditions set forth in SECTION 7 capable of satisfaction or waiver prior to Closing (the “Closing Date”), at the offices of Ropes & Gray, LLP, One International Place, Boston, Massachusetts 02110, unless another date or place is agreed to in writing by the parties hereto.

1.6. Directors and Officers of the Surviving Corporation. The directors of Sub immediately prior to the Effective Time shall, from and after the Effective Time, be the directors of the Surviving Corporation, and the officers of Sub immediately prior to the Effective Time shall, from and after the Effective Time, be the officers of the Surviving Corporation, in each case until their respective successors shall have been duly elected, designated or qualified, or until their earlier death, resignation or removal in accordance with the Surviving Corporation’s

certificate of incorporation and bylaws. Prior to the Effective Time, the Company shall cause each member of the Company Board of Directors, other than Parent’s or Sub’s designees pursuant to Section 6.9, to execute and deliver a letter effectuating his or her resignation as a director of the Company upon the Effective Time.

1.7. Subsequent Actions. If at any time after the Effective Time the Surviving Corporation shall determine, in its sole discretion, or shall be advised, that any deeds, bills of sale, assignments, assurances or any other actions or things are necessary or desirable to vest, perfect or confirm of record or otherwise in the Surviving Corporation its right, title or interest in, to or under any of the rights, properties or assets of either of the Company or Sub acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger or otherwise to carry out this Agreement, then the officers and directors of the Surviving Corporation shall be authorized to execute and deliver, in the name and on behalf of either the Company or Sub, all such deeds, bills of sale, instruments of conveyance, assignments and assurances and to take and do, in the name and on behalf of each such corporation or otherwise, all such other actions and things as may be necessary or desirable to vest, perfect or confirm any and all right, title or interest in, to and under such rights, properties or assets in the Surviving Corporation or otherwise to carry out this Agreement.

(a) If required by applicable Law in order to consummate the Merger, the Company, acting through the Company Board of Directors, in accordance with applicable Law and the Company’s certificate of incorporation and bylaws, shall, as soon as reasonably practicable following the Tender Completion Time:

(i) duly call, give notice of, convene and hold a special meeting of its stockholders to consider the adoption of this Agreement and the approval of the Merger (the “Special Meeting”);

(ii) prepare and file with the SEC under the Exchange Act a preliminary proxy or information statement relating to the Merger and this Agreement and use its reasonable best efforts to obtain and furnish the information required to be included by the SEC in the Proxy Statement (as hereinafter defined) and, after Parent shall have had a reasonable opportunity to review and comment on the Proxy Statement, respond promptly to any comments made by the SEC with respect to the preliminary proxy or information statement and cause a definitive proxy or information statement (in either case, the “Proxy Statement”) to be mailed to its stockholders as promptly as practicable;

(iii) subject to Section 5.2, include in the Proxy Statement the recommendation of the Company Board of Directors that stockholders of the Company vote in favor of the adoption of this Agreement and the approval of the Merger; and

(iv) use its reasonable best efforts to solicit from holders of Shares proxies in favor of the adoption of this Agreement and the approval of the Merger and take all other action reasonably necessary or advisable to secure the approval of stockholders required by the DGCL and any other applicable Law and the Company’s certificate of incorporation and bylaws (if applicable) to effect the Merger.

(b) Parent agrees to vote, or cause to be voted, all of the Shares then beneficially owned by it or Sub in favor of the adoption of this Agreement and the approval of the Merger.

1.9. Merger Without Meeting of Stockholders. Notwithstanding Section 1.8, in the event that Parent, Sub or any other subsidiary of Parent shall acquire at least ninety percent (90%) of the outstanding shares of each class of capital stock of the Company entitled to vote on the Merger, pursuant to the Offer or otherwise, the parties hereto agree, at the request of Parent and subject to SECTION 7, to take all necessary and appropriate action to cause the Merger to become effective as soon as practicable after such acquisition, without a meeting of stockholders of the Company, in accordance with and subject to the DGCL.

(a) The Company hereby grants to Sub an irrevocable option (the “Top-Up Option”), exercisable only on the terms and subject to the conditions set forth in this Agreement, to purchase at a price per share equal to the Offer Price paid in the Offer that number of newly issued Shares (the “Top-Up Shares”) equal to the lowest number of Shares that, when added to the number of Shares directly or indirectly owned by Parent or Sub at the time of exercise of the Top-Up Option, shall constitute one share more than ninety percent (90%) of the Shares outstanding immediately after the issuance of the Top-Up Shares (determined on a fully diluted basis); provided, however, that (i) the Top-Up Option shall not be exercisable for a number of Shares in excess of the Shares authorized and unissued at the time of exercise of the Top-Up Option and (ii) the Top-Up Option may not be exercised unless, following the Acceptance Time or after a subsequent offering period, eighty percent (80%) or more of the Shares shall be directly or indirectly owned by Parent or Sub. The Top-Up Option shall be exercisable only once at any time following the Acceptance Time and prior to the earlier to occur of (A) the Effective Time and (B) the termination of this Agreement in accordance with its terms.

(b) The parties shall cooperate to ensure that the issuance and delivery of the Top-Up Shares comply with all applicable Laws, including compliance with an applicable exemption from registration of the Top-Up Shares under the Securities Act. If Sub wishes to exercise the Top-Up Option, Sub shall give the Company one (1) business day prior written notice, specifying (i) the number of Shares directly or indirectly owned by Parent at the time of such notice and (ii) a place and a time for the closing of such purchase. The Company shall, as soon as practicable following receipt of such notice, deliver written notice to Sub specifying, based on the information provided by Sub in its notice, the number of Top-Up Shares. At the closing of the purchase of Top-Up Shares, the purchase price owed by Sub to the Company therefor shall be paid to the Company (A) in cash, by wire transfer or cashier’s check or (B) by issuance by Sub to the Company of a promissory note on terms reasonably satisfactory to the Company.

2.1. Conversion of Capital Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of the holders of any Shares or any shares of common stock, par value $0.01 per share, of Sub (“Sub Common Stock”):

(a) Sub Common Stock. Each issued and outstanding share of Sub Common Stock shall be converted into and become one (1) fully paid and nonassessable share of common stock of the Surviving Corporation.

(b) Cancellation of Treasury Stock and Parent-Owned Stock. All Shares that are owned by the Company as treasury stock and any Shares owned by Parent or Sub shall automatically be cancelled and retired and shall cease to exist, and no consideration shall be payable in exchange therefor.

(c) Conversion of Shares. Each issued and outstanding Share (other than Shares to be cancelled in accordance with Section 2.1(b) and other than Dissenting Shares (as defined in Section 2.3(a))) shall be converted into the right to receive the Offer Price, payable to the holder thereof in cash, without interest (the “Merger Consideration”). From and after the Effective Time, all such Shares shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each holder of a certificate (a “Certificate”) or book-entry share (a “Book-Entry Share”) representing any such Shares shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration therefor, without interest thereon, upon the surrender of such certificate or book-entry share in accordance with Section 2.2.

(a) Paying Agent. Parent shall designate Computershare Trust Company, N.A. or another bank or trust company that is reasonably acceptable to the Company to act as agent for the holders of Shares in connection with the Merger (the “Paying Agent”) and to receive the funds to which holders of Shares shall become entitled pursuant to Section 2.1(c). Parent shall cause the Surviving Corporation to provide to the Paying Agent on a timely basis, promptly after the Effective Time and as and when needed after the Effective Time, cash necessary to pay for the Shares converted into the right to receive the Merger Consideration (such cash being hereinafter referred to as the “Exchange Fund”). If for any reason the Exchange Fund is inadequate to pay the amounts to which holders of Shares shall be entitled under Section 2.1(c), Parent shall promptly deposit or cause the Surviving Corporation promptly to deposit additional cash with the Paying Agent sufficient to make all payments of Merger Consideration, and Parent and the Surviving Corporation shall in any event be liable for payment thereof. The Paying Agent may invest the cash in the Exchange Fund as directed by Parent; provided, however, that such investments shall be in obligations of or guaranteed by the United States or any agency or instrumentality thereof and backed by the full faith and credit of the United States, in commercial paper obligations rated P-1 or A-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation, respectively, in money market funds that invest only in such United States government and commercial paper obligations, or in certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $1 billion (based on the most recent financial statements of such bank that are then publicly available). Any interest and other income resulting from such investments shall be paid to Parent.

(b) Exchange Procedures. Promptly after the Effective Time, the Paying Agent shall mail to each holder of record of a Certificate or a Book-Entry Share, which immediately prior to the Effective Time represented outstanding Shares, whose Shares were converted pursuant to Section 2.1(c) into the right to receive the Merger Consideration (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates or Book-Entry Shares, as applicable, shall pass, only upon delivery of the Certificates or Book-Entry Shares to the Paying Agent and shall be in such form and have such other provisions as Parent may reasonably specify); and (ii) instructions for effecting the surrender of the Certificates or Book-Entry Shares in exchange for payment of the Merger Consideration. Upon surrender of a Certificate or Book-Entry Share, as applicable, for cancellation to the Paying Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly executed and properly completed and such other documents as may be reasonably requested by the Paying Agent, the holder of such Certificate or Book-Entry Share shall be entitled to receive in exchange therefor the Merger Consideration for each Share, formerly represented by such Certificate or Book-Entry Share, and the Certificate or Book-Entry Share so surrendered shall forthwith be cancelled. Until surrendered as contemplated by this Section 2.2, each Certificate or Book-Entry Share, as applicable, shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration in cash as contemplated by this Section 2.2, without interest thereon, and shall not evidence any interest in, or any right to exercise the rights of a stockholder or other equity holder of, the Company or the Surviving Corporation.

(c) Transfer Books; No Further Ownership Rights in Shares. At the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of Shares on the records of the Company. From and after the Effective Time, the holders of Certificates or Book-Entry Shares evidencing ownership of Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares, except as otherwise provided for herein or by applicable Law. If, after the Effective Time, Certificates or Book-Entry Shares are presented to the Surviving Corporation for any reason, they shall be cancelled and exchanged as provided in this SECTION 2.

(d) Termination of Exchange Fund; No Liability. At any time following nine (9) months after the Effective Time, the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) made available to the Paying Agent and not disbursed (or for which disbursement is pending subject only to the Paying Agent’s routine administrative procedures) to holders of Certificates, and thereafter such holders shall be entitled to look only to the Surviving Corporation (subject to abandoned property, escheat or other similar Laws) only as general creditors thereof with respect to the Merger Consideration payable upon due surrender of their Certificates or Book-Entry Shares, as applicable, without any interest thereon. Notwithstanding the foregoing, none of Parent, the Surviving Corporation nor the Paying Agent shall be liable to any holder of a Certificate or Book-Entry Share, as applicable, for Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If Certificates or Book-Entry Shares, as applicable, are not surrendered prior to two (2) years after the Effective

Time, unclaimed Merger Consideration payable with respect to such Shares shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, free and clear of all claims or interest of any person previously entitled thereto.

(e) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such person of a bond in such amount as Parent may reasonably direct as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Paying Agent shall issue in exchange for such lost, stolen or destroyed Certificate the applicable Merger Consideration with respect thereto.

(a) Notwithstanding anything in this Agreement to the contrary, Shares outstanding immediately prior to the Effective Time and held by a holder who has not voted in favor of the Merger or consented thereto in writing and who has complied with Section 262 of the DGCL (the “Dissenting Shares”) shall not be converted into a right to receive the Merger Consideration, unless such holder fails to perfect or withdraws or otherwise loses his, her or its right to appraisal. From and after the Effective Time, a stockholder who has properly exercised such appraisal rights shall not have any rights of a stockholder of the Company or the Surviving Corporation with respect to such Shares, except those provided under Section 262 of the DGCL. A holder of Dissenting Shares shall be entitled to receive payment of the appraised value of such Shares held by him, her or it in accordance with Section 262 of the DGCL, unless, after the Effective Time, such holder fails to perfect or withdraws or loses his, her or its right to appraisal, in which case such Shares shall be converted into and represent only the right to receive the Merger Consideration, without interest thereon, upon surrender of the Certificate or Certificates, pursuant to Section 2.2.

(b) The Company shall give Parent (i) prompt written notice of any written demands for appraisal (including copies of such demands), attempted withdrawals of such demands and any other instruments received by the Company relating to rights of appraisal; and (ii) the opportunity to participate in the conduct of all negotiations and proceedings with respect to demands for appraisal. Except with the prior written consent of Parent, the Company shall not voluntarily make any payment with respect to any demands for appraisal or settle or offer to settle any such demands for appraisal.

(a) Effective as of the Effective Time, each outstanding stock option, stock equivalent right or right to acquire Shares (each a “Company Option” and collectively, the “Company Options”) granted under the Company’s Amended and Restated 2000 Equity Incentive Plan and 1995 Stock Plan (the “Company Stock Plans”), without regard to the extent then vested and exercisable, shall be cancelled and, in consideration of such cancellation, Parent shall, or shall cause the Surviving Corporation to, promptly following the Effective Time, pay to such holders of Company Options, an amount in respect thereof equal to the product of (x) the excess, if any, of the Offer Price over the exercise price of each such Company Option and (y) the number of unexercised Shares subject thereto (such payment, if any, to be net of applicable Taxes withheld pursuant to Section 2.6).

(b) Effective as of the Effective Time, each restricted stock unit, representing a right to receive one Share (each a “Company RSU” and collectively, the “Company RSUs”) granted under any Company Stock Plan, which is outstanding immediately prior to the Effective Time will become fully vested (provided, however, that only 1,250 of the 5,000 Company RSUs granted in 2009 pursuant to Section 12 of the Company’s Amended and Restated 2000 Equity Incentive Plan to each of the independent members of the Company Board of Directors, which are outstanding immediately prior to the Effective Time, will become vested as of the Effective Time) and then will be cancelled at the Effective Time, and in consideration of such cancellation, Parent shall, or shall cause the Surviving Corporation to, promptly following the Effective Time, pay to such holders of Company RSUs, an amount in respect thereof equal to the product of (x) the Offer Price and (y) the number of Shares into which the vested portion of the Company RSU would otherwise be convertible (such payment, if any, to be net of applicable Taxes withheld pursuant to Section 2.6).

(c) As of the Effective Time, the Company Stock Plans shall terminate and all rights under any provision of any other plan, program or arrangement providing for the issuance or grant of any other interest in respect of the capital stock of the Company or any Company Subsidiary (as defined in Section 3.4(a)) shall be cancelled. The Company shall use all reasonable efforts to effectuate the foregoing, including, but not limited to, sending out the requisite notices and obtaining all consents necessary to cash out and cancel all Company Options and Company RSUs necessary to ensure that, after the Effective Time, no person shall have any right under the Company Stock Plans, except as set forth herein.

2.5. Section 16. The Company Board of Directors shall, to the extent necessary, take appropriate action, prior to or as of the Acceptance Time, to approve, for purposes of Section 16(b) of the Exchange Act the disposition and cancellation of Shares (including derivative securities with respect to Shares) resulting from the transactions contemplated by this Agreement.

2.6. Withholding. Each of Parent and Surviving Corporation shall be entitled to deduct and withhold, or cause the Paying Agent to deduct and withhold, from any amounts payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of Shares, Company Options or Company RSUs such amounts as are required to be deducted and withheld therefrom under the United States Internal Revenue Code of 1986, as amended (the “Code”) or the Treasury Regulations thereunder or any other Tax Law. To the extent such amounts are so deducted and withheld, and such deduction and withholding would have been required were Parent incorporated or organized in the United States or a subdivision thereof, such amounts shall be treated for all purposes under this Agreement as having been paid to the person to whom such amounts would otherwise have been paid. To the extent that such amounts are required to be deducted and withheld under the Tax Law of a jurisdiction outside the United States, and such deduction and withholding would not have been required were Parent incorporated or organized in the United States or a subdivision thereof, Parent or the Surviving Corporation shall, or shall cause the Paying Agent to, pay to the applicable holder or former holder of Shares, Company Options or Company RSUs such additional amounts as necessary to ensure that such holder or former holder receives the same amount that would otherwise have been received if no such deduction and withholding had been made.

2.7. Transfer Taxes. If any payment pursuant to the Offer or the Merger is to be made to a person other than the person in whose name the surrendered Certificate or Book-Entry Share, as applicable, is registered, it shall be a condition of payment that the Certificate or Book-Entry Share, as applicable, so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and that the person requesting such payment shall have paid all transfer and other Taxes required by reason of the issuance to a person other than the registered holder of the Certificate or Book-Entry Share, as applicable, surrendered or shall have established to the satisfaction of Parent that such Tax either has been paid or is not applicable. Any other transfer Taxes shall be paid by Parent.

Except as set forth on the disclosure schedule delivered by the Company to Parent on the date hereof (the “Company Disclosure Schedule”), the Section numbers of which are numbered to correspond to the Section numbers of this Agreement to which they refer (provided, however, that an item disclosed in any Section shall be deemed to have been disclosed for each other Section of this Agreement to the extent the relevance of such disclosure to such other Section of this Agreement is reasonably apparent on the face of such disclosure), the Company hereby makes the following representations and warranties to, and agreements with, Parent and Sub:

(a) The Company is a corporation duly incorporated, validly existing and in good standing under the Laws of its jurisdiction of incorporation and has corporate power and authority to own, lease and operate its assets and to carry on its business as now being conducted. The Company is qualified to transact business as a foreign corporation in all jurisdictions in which such qualification is required by Law, except for jurisdictions in which the failure to be so qualified and in good standing would not reasonably be expected to have a Company Material Adverse Effect. “Company Material Adverse Effect” shall mean any change, event, circumstance, effect or development that, individually or in the aggregate with all other changes, events, circumstances, effects or developments that exist on the date of determination of the occurrence of a Company Material Adverse Effect, has had or is reasonably likely to have a material adverse effect on (i) the assets, properties, business, capitalization, results of operations or condition (financial or other) of the Company and the Company Subsidiaries, taken as a whole or (ii) the ability of the Company to consummate the transactions contemplated by this Agreement; provided, however, that in no event shall changes, events, circumstances, effects or developments to the extent resulting from any of the following be taken into account in determining whether there is, has been or is reasonably likely to be a “Company Material Adverse Effect”: (A) changes in conditions of the economy or securities markets of the United States in general that in each case, do not have a disproportionate impact on the Company and the Company Subsidiaries, taken as a whole, relative to other persons engaged in business in the medical device industry, (B) changes in conditions affecting the medical device industry, in each case, without a disproportionate impact on the Company and the Company Subsidiaries, taken as a whole, relative to other persons engaged in business in the medical device industry, (C)

changes to applicable Law or generally accepted accounting principles or, in either case, the interpretation thereof that do not have a disproportionate impact on the Company and the Company Subsidiaries, taken as a whole, relative to other persons engaged in business in the medical device industry, (D) any change in the trading price or trading volume of the Shares (it being understood that the underlying facts or circumstances giving rise to any such change may be taken into account in determining whether there has been or is likely to be a Company Material Adverse Effect if such facts and circumstances are not otherwise excluded pursuant to clauses (A) through (F) of this definition), (E) the announcement of the execution of this Agreement or the pendency of the transactions contemplated hereby, or (F) any failure of the Company to meet securities analysts’ published or internal projections or forecasts or estimates of earnings or revenues (it being understood that the underlying facts or circumstances giving rise to any such failure may be taken into account in determining whether there has been or is likely to be a Company Material Adverse Effect if such facts and circumstances are not otherwise excluded pursuant to clauses (A) through (F) of this definition).

(b) The Company has previously provided to Parent true and complete copies of the certificate of incorporation and bylaws or other organizational documents of the Company and each Company Subsidiary as presently in effect, and none of the Company or any Company Subsidiary is in default in the performance, observation or fulfillment of such documents, except, in the case of the Company Subsidiaries, such defaults that, in the aggregate, would not reasonably be expected to have a Company Material Adverse Effect.

The Company and each Company Subsidiary has good and marketable title to all of its properties, interests in properties and assets, real and personal, reflected in the Company Balance Sheet (except properties, interests in properties and assets sold or otherwise disposed of since the date of the Company Balance Sheet in the ordinary course of business consistent with past practice), or with respect to leased properties and assets, valid leasehold interests in such properties and assets, in each case, free and clear of all imperfections of title, restrictions, encroachments, liens and easements, except (i) liens for current Taxes not yet due and payable, that are payable without penalty or that are being contested in good faith by appropriate proceedings, (ii) such imperfections of title, restrictions, encroachments, liens and easements as do not and could not reasonably be expected to materially detract from or interfere with the use or value of the properties subject thereto or affected thereby, or otherwise materially impair business operations involving such properties and (iii) liens securing debt which are reflected on the Company Balance Sheet. There are no written or oral subleases, licenses, occupancy agreements or other contractual obligations that grant the right of use or occupancy of any real property leased by the Company or any Company Subsidiary (collectively, the “Real Property”), and there is no person in possession of the Real Property other than the Company and the Company Subsidiaries. There is no pending, or, to the knowledge of the Company, threatened eminent domain, condemnation or similar proceeding affecting any Real Property leased by the Company or a Company Subsidiary. To the knowledge of the Company, the property and equipment of the Company and each Company Subsidiary that are used in the operations of business are (i) in good operating

Neither the Company nor any Company Subsidiary is in default in any material respect with respect to any provision contained in such policy or binder nor has any of the Company or a Company Subsidiary failed to give any notice or present any material claim under any such policy or binder in due and timely fashion. All premiums for each policy or binder have been paid for the current period, and there are no outstanding premium finance payments due for such period.

Except as described in Section 3.16(b) of the Company Disclosure Schedule, the transactions contemplated by this Agreement will not, by themselves or together with any other event, cause or result in the payment, acceleration or vesting of any payment, right or benefit under any Plan.

(c) Each Plan that is intended to be qualified under Section 401(a) of the Code is the subject of a favorable determination or opinion letter from the Internal Revenue Service

(d) Each Plan has been maintained and administered at all times in accordance with its material terms. Each Plan, including any associated trust or fund, has been established and administered in material compliance with the applicable provisions of ERISA, the Code and other applicable Law (including, where applicable, non-U.S. Law), and, to the knowledge of the Company, nothing has occurred with respect to any Plan that has subjected or could reasonably be expected to subject the Company or any ERISA Affiliate to any liability or penalty under Section 502 of ERISA or to any tax under Chapter 43 of the Code. All filings and reports with respect to each Plan required to have been submitted to the IRS, the United States Department of Labor, or any other Governmental Entity have been duly and timely submitted.

(e) No Plan provides health or life insurance benefits following retirement or other termination of employment, and neither the Company nor any Company Subsidiary has any obligation to provide any such benefits following retirement or other termination of employment, in each case except for benefit continuation coverage to the extent required under Part 6 of Subtitle B of Title I of ERISA.

(f) With respect to each Plan, no administrative investigation, inquiry, audit or other proceeding by the IRS, Department of Labor other Governmental Entity, and no other lawsuit, claim, or other controversy, other than claims for benefits in the ordinary course and proceedings with respect to qualified domestic relations orders, is pending or, to the knowledge of the Company, threatened.

(h) Each Plan subject to Section 409A of the Code (“Section 409A”) has been operated in good faith compliance with Section 409A. No Plan, which is subject to the requirements of Section 409A, violates such requirements.

(j) Each Plan and its related documentation or agreement, summary plan description, or other written communication distributed generally to employees by its terms expressly and adequately reserves the right to amend and terminate such Plan, and each Plan may be terminated without material liability to the Company or any Company Subsidiary, except for vested benefits accrued through the date of termination and the administrative and professional costs incurred in such transaction. Except as listed in Section 3.16(j) of the Company Disclosure Schedule, no Plan includes in its assets any securities issued by the Company or any of Company Subsidiary.

(a) Except as otherwise provided in this Section 3.17(a), upon termination of the employment of any employees or the service relationship of any director or consultant, none of the Company, the Company Subsidiaries, the Surviving Corporation nor Parent shall be liable, by reason of the Offer or Merger, to any of such employees, directors, or consultants for severance pay or any other similar payments (other than accrued salary, vacation or sick pay in accordance with normal policies), except as set forth in Section 3.17(a) of the Company Disclosure Schedule.

(c) No work stoppage or labor strike against the Company or any Company Subsidiary is pending or, to the knowledge of the Company, threatened. Neither the Company nor any Company Subsidiary is involved in or, to the knowledge of the Company, threatened with, any labor dispute, grievance, or litigation relating to labor, safety or discrimination matters involving any employee, including without limitation charges of unfair labor practices or discrimination complaints that, if adversely determined, could reasonably be expected to result in material liability to the Company.

(b) Notwithstanding anything to the contrary set forth in this Agreement, prior to the Acceptance Time, the Company and its Representatives may furnish non-public information regarding the Company to any person and may negotiate and participate in discussions and negotiations with such person concerning an Acquisition Proposal if, but only if, such person has, in the absence of any material violation of this Section 5.2 by the Company, submitted a bona fide written proposal to the Company relating to any such Acquisition Proposal

which the Board of Directors determines in good faith, after consultation with its financial advisor, is or is reasonably expected to lead to a Superior Proposal.

The Company will promptly provide to the Parent any non-public information concerning the Company or the Company Subsidiaries provided or made available pursuant to this Section 5.2(b) which was not previously provided or made available to the Parent.

(c) Except as set forth herein, neither the Company Board of Directors nor any committee thereof shall (i) withdraw, withhold, qualify or modify, or propose publicly to withdraw, withhold, qualify or modify, in a manner adverse to the transactions contemplated by this Agreement to Parent or Sub, the Company Board Recommendation, (ii) approve or recommend or propose publicly to approve or recommend, any Acquisition Proposal (any action referred to in the foregoing clauses (i) and (ii) being referred to as an “Adverse Recommendation Change”) or (iii) enter into any written agreement providing for the consummation of any Acquisition Proposal (an “Alternative Acquisition Agreement”).

(d) Notwithstanding anything in this Agreement to the contrary, prior to the Acceptance Time, if (i) the Company receives a written, bona fide Acquisition Proposal from a third party, (ii) a material breach by the Company of this Section 5.2 has not contributed to the making of an Acquisition Proposal and (iii) the Company Board of Directors concludes in good faith, after consultation with outside counsel and its financial advisors, such Acquisition Proposal constitutes a Superior Proposal after giving effect to all of the adjustments to the terms of this Agreement which have been offered by Parent (if any) pursuant to this Section 5.2, the Company Board of Directors may, if it determines in good faith, after consultation with outside counsel, that failure to take such action would be inconsistent with the fiduciary duties of the Company Board of Directors to the stockholders of the Company under applicable Law, (A) effect an Adverse Recommendation Change and/or (B) terminate this Agreement to enter into an Alternative Acquisition Agreement with respect to such Superior Proposal; provided, however, that the Company shall not terminate this Agreement pursuant to the foregoing clause (B), and any purported termination pursuant to the foregoing clause (B) shall be void and of no force or effect, unless in advance of or substantially concurrently with such termination the Company (1) pays the fee required by and pursuant to the terms of Section 8.2 and (2) immediately following such termination enters into a binding definitive agreement providing for such Superior Proposal; and provided, further, that the Company Board of Directors may not effect an Adverse Recommendation Change pursuant to the foregoing clause (A) or terminate this Agreement pursuant to the foregoing clause (B) unless (1) the Company shall not have breached in any material respect this Section 5.2, (2) the Company shall have provided prior written notice to the Parent, at least three (3) business days in advance (the “Notice Period”), of the Company’s intention to take such action with respect to such Superior Proposal, which notice shall specify the material terms and conditions of any such Superior Proposal (including the identity of the party making such Superior Proposal), and shall have contemporaneously provided a copy of the proposed Alternative Acquisition Agreement with respect to such Superior Proposal, (3) prior to effecting such Adverse Recommendation Change or terminating this Agreement to enter into a definitive Alternative Acquisition Agreement with respect to such Superior Proposal, the Company shall, and shall cause its Representatives to, during the Notice Period, negotiate with the Parent in good faith (to the extent the Parent desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such Acquisition Proposal ceases to constitute a Superior Proposal, and (4) following any negotiation described in the immediately preceding clause (3), such Acquisition Proposal continues to constitute a Superior Proposal. In the event of any material revisions to the terms of the Superior Proposal after the start of the Notice Period, the Company shall be required to deliver a new written notice to the Parent and to comply with the requirements of this Section 5.2 with respect to such new written notice, and the Notice Period shall be deemed to have re-commenced on the date of such new notice. Notwithstanding the foregoing, if fewer than three (3) business days remains before the then-scheduled expiration date of the Offer, the Notice Period with respect to the Company Board of Directors effecting an Adverse Recommendation Change pursuant to the foregoing clause (A) shall equal twenty-four (24) hours, provided, however, that, in such a circumstance, the Notice Period with respect to the Company terminating this Agreement pursuant to the foregoing clause (B) shall remain three (3) business days. Any Adverse Recommendation Change shall not change the approval of the Company Board of Directors for purposes of causing any state

takeover statute or other state Law to be inapplicable to the transactions contemplated by this Agreement, including each of the Offer and the Merger or by the tender and voting Agreements with Principal Stockholders. For purposes of this Agreement, a “Superior Proposal” is a bona fide written Acquisition Proposal to acquire at least fifty percent (50%) of the equity securities of the Company or at least fifty percent (50%) of the consolidated total assets of the Company and the Company Subsidiaries, (A) on terms which the Company Board of Directors determines in its good faith judgment (after consultation with its financial advisors) to be more favorable to the holders of Shares from a financial point of view than the Offer and the Merger, and (B) which the Company Board of Directors has determined in its good faith judgment (after consultation with its financial and legal advisors) to be reasonably capable of being completed on the terms proposed, taking into account all financial, regulatory, legal and other aspects of such proposal.

(e) Notwithstanding the foregoing, the Company Board of Directors may withdraw or modify the Company Board Recommendation in the absence of a Superior Proposal if the Company Board of Directors has concluded in good faith, after consultation with its outside counsel, that failure to so withdraw or modify the Company Board Recommendation would be inconsistent with the fiduciary obligations of the Company Board of Directors to the stockholders of the Company under applicable Law, provided, however, that the Company Board of Directors shall not so withdraw or modify the Company Board Recommendation unless the Company has (A) provided to the Parent at least three (3) business days prior written notice (or such shorter period as remains prior to the then-scheduled expiration date of the Offer) advising the Parent that the Company Board of Directors intends to take such action and specifying the reasons therefore in reasonable detail and (B) during such three (3) business day period, or shorter period, as the case may be, if requested by the Parent, engaged in good faith negotiations with the Parent to amend this Agreement in such a manner that obviates the need or reason for the withdrawal or modification.

(f) The Company shall promptly (but in no event later than two (2) business days after the date of this Agreement) demand that each person that, as of the date of this Agreement, has executed a confidentiality agreement in connection with a potential Acquisition Proposal return (or destroy, to the extent permitted by the terms of the applicable confidentiality agreement) all confidential information heretofore furnished to such individual or entity by or on behalf of the Company or a Company Subsidiary.

6.1. Proxy Statement. If required by the Exchange Act, the Company shall, as soon as practicable following the expiration of the Offer, prepare and file with the SEC the Proxy Statement in preliminary form, and each of the Company, Parent and Sub shall use all commercially reasonable efforts to respond as promptly as practicable to any comments of the SEC with respect thereto. The Company shall notify Parent promptly of the receipt of any comments from the SEC or its staff and of any request by the SEC or its staff for amendments or supplements to the Proxy Statement or for additional information and shall supply Parent with copies of all correspondence between the Company or any of its representatives, on the one hand, and the SEC or its staff, on the other hand, with respect to the Proxy Statement. If at any time prior to receipt of the adoption of this Agreement by the required vote of the holders of the outstanding Shares (the “Company Stockholder Approval”) there shall occur any event that

should be set forth in an amendment or supplement to the Proxy Statement, the Company shall promptly prepare and mail to its stockholders such an amendment or supplement to the extent required by applicable Law. The Company shall not mail any Proxy Statement, or any amendment or supplement thereto, to which Parent reasonably objects. The Company shall use all commercially reasonable efforts to cause the Proxy Statement to be mailed to the Company’s stockholders as promptly as practicable after filing with the SEC. Subject to the terms and conditions of this Agreement, the Proxy Statement shall contain the recommendation of the Company Board of Directors in favor of the Merger.

6.2. Meeting of Stockholders of the Company. If, following the Tender Completion Time, the adoption of this Agreement by the holders of Shares is required under the DGCL in order to consummate the Merger, the Company shall take all actions in accordance with applicable Law, the Company’s certificate of incorporation and bylaws and the rules of The Nasdaq Stock Market to promptly and duly call, give notice of, convene and hold as promptly as practicable, a Special Meeting. For purposes of this Agreement, the term “Tender Completion Time” means the latest to occur of (x) the Acceptance Time, (y) the closing of the purchase of the Top-Up Shares or the failure by Sub to exercise the Top-Up Option during the exercise period provided in Section 1.10 and (z) if at least one subsequent offering period is commenced by Sub, the expiration of the last subsequent offering period related to the Offer.

6.3. Nasdaq; Post-Closing SEC Reports. Prior to the Effective Time, the Company shall cooperate with the Parent and use reasonable best efforts to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under applicable Laws and rules and policies of The Nasdaq Stock Market to enable the delisting by the Surviving Corporation of the Shares from The Nasdaq Stock Market and the deregistration of the Shares under the Exchange Act promptly after the Effective Time. Parent will use all commercially reasonable efforts to cause the Surviving Corporation to file with the SEC (a) a Form 25 on the Closing Date and (b) a Form 15 on the first business day that is at least ten (10) days after the date the Form 25 is filed (such period between the Form 25 filing date and the Form 15 filing date, the “Delisting Period”). If the Surviving Corporation is reasonably likely to be required to file any reports pursuant to the Exchange Act during the Delisting Period, the Company will deliver to Parent at least five (5) business days prior to the Closing a substantially final draft of any such reports reasonably likely to be required to be filed during the Delisting Period (“Post-Closing SEC Reports”). The Post-Closing SEC Reports provided by the Company pursuant to this Section 6.3 will (i) not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading and (ii) comply in all material respects with the provisions of applicable Laws.

6.4. Access to Information. Prior to the Effective Time, Parent shall be entitled, through its employees and representatives, to have such access to the assets, properties, business and operations of the Company and the Company Subsidiaries as is reasonably necessary or appropriate in connection with Parent’s investigation of the Company with respect to the transactions contemplated hereby. Any such investigation and examination shall be conducted at reasonable times during business hours upon reasonable advance notice and under reasonable circumstances so as to minimize disruption to or impairment of the Company’s business. No investigation by Parent shall diminish or obviate any of the representations, warranties,

covenants or agreements of the Company contained in this Agreement. The Company shall furnish the representatives of Parent during such period with all such information and copies of such documents concerning the affairs of the Company as such representatives may reasonably request and cause its officers, employees, consultants, agents, accountants and attorneys to cooperate fully with such representatives in connection with such investigation. The information and documents so provided shall be subject to the terms of the Confidentiality Agreement. Neither the Company nor any Company Subsidiary shall be required to provide access to or to disclose information where such access or disclosure would contravene any Law or binding agreement entered into prior to the date of this Agreement or would reasonably be expected to violate or result in a loss or impairment of any attorney-client or work product privilege.

6.5. Public Disclosure. The initial press release concerning the Offer and the Merger shall be a joint press release and, thereafter, subject to the other terms of this Agreement (including Section 5.2), so long as this Agreement is in effect, neither Parent, Sub nor the Company will disseminate any press release or other announcement concerning the Merger, the Offer or this Agreement or the other transactions contemplated by this Agreement to any third party, except as may be required by Law or by any listing agreement with The Nasdaq Stock Market, without the prior consent of each of the other parties hereto, which consent shall not be unreasonably withheld, conditioned or delayed. The parties have agreed to the text of the joint press release announcing the execution of this Agreement. Notwithstanding the foregoing, without prior consent of the other party, each party (a) may communicate information that is not confidential to the other party with financial analysts, investors and media representatives in a manner consistent with its past practice in compliance with applicable Law and (b) may disseminate material substantially similar to material included in a press release or other document previously approved for external distribution by the other parties. Each party agrees to promptly make available to the other parties copies of any written communications made without prior consultation with the other parties.

(a) As promptly as practicable after the date hereof, each of Parent, Sub and the Company shall make all filings, notices, petitions, statements, registrations, submissions of information, application or submission of other documents required under applicable Law by any Governmental Entity of competent jurisdiction in connection with the Offer, the Merger and the other transactions contemplated hereby, including, without limitation: (i) Notification and Report Forms with the United States Federal Trade Commission and the Antitrust Division of the United States Department of Justice as required by the HSR Act, (ii) filings required by the merger notification or control Laws of the foreign jurisdictions listed on Annex I-A, and (iii) any filings required under the Securities Act, the Exchange Act, any applicable state or securities or “blue sky” Laws and the securities Laws of any foreign country, or any other applicable Laws or rules and regulations of any Governmental Entity relating to the Offer and the Merger. Each of Parent and the Company will cause all documents that it is responsible for filing with any Governmental Entity under this Section 6.6 to comply in all material respects with all applicable Laws of any Governmental Entity.

(b) Each of Parent, Sub, and the Company shall promptly supply the other with any information which may be reasonably required in order to effectuate any filings or application pursuant to this Section 6.6.

(c) Each of Parent, Sub and the Company will notify the others promptly upon the receipt of: (i) any comments from any officials of any Governmental Entity in connection with any filings made pursuant hereto and (ii) any request by any officials of any Governmental Entity for amendments or supplements to any filings made pursuant to, or information provided to comply in all material respects with, any applicable Laws and rules and regulations of any Governmental Entity. Whenever any event occurs that is required to be set forth in an amendment or supplement to any filing made pursuant to Section 6.6(a), Parent, Sub or the Company, as the case may be, will promptly inform the others of such occurrence and cooperate in filing with the applicable Governmental Entity such amendment or supplement.

(d) Upon the terms and subject to the conditions set forth in this Agreement, each of the parties agrees to use reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Offer, the Merger and the other transactions contemplated hereby, including complying in all material respects with all applicable Laws and with all rules and regulations of any Governmental Entity and using reasonable best efforts to accomplish the following: (i) the causing of all the conditions set forth in SECTION 7 and in Annex I hereto to be satisfied and to consummate and make effective the Offer, the Merger and the other transactions contemplated hereby, (ii) the obtaining of all reasonably requested actions or nonactions, waivers, consents, clearances, approvals, orders and authorizations from Governmental Entities and the making of all reasonably requested registrations, declarations and filings (including registrations, declarations and filings with Governmental Entities, if any), (iii) the obtaining of all reasonably requested consents, approvals or waivers from third parties, (iv) the defending of any suits, claims, actions, investigations or proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated hereby, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Entity vacated or reversed, and (v) the execution or delivery of any additional instruments necessary to consummate the transactions contemplated hereby, and to carry out fully the purposes of, this Agreement. In connection with and without limiting the foregoing, the Company and its Board of Directors shall, if any state takeover statute or similar statute or regulation is or becomes applicable to the Offer, the Merger, this Agreement or any of the other transactions contemplated hereby, use all reasonable best efforts to ensure that the Offer, the Merger and the other transactions contemplated hereby may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on the Offer, the Merger, this Agreement and the other transactions contemplated hereby. The Company will use reasonable best efforts to obtain any consent, approval, or waiver with respect to the Material Contracts such that no party will have a reasonable basis to maintain that the representations and warranties in Section 3.11 and clause “(ii)” of Section 3.19 are not true and correct. Nothing in this Agreement shall require Parent, the Surviving Corporation or any other subsidiary of Parent to sell, hold separate, license or otherwise dispose of any assets or conduct their business in a specified manner, or agree or proffer to sell, hold separate, license or otherwise dispose of any assets or conduct their business

in a specified manner, or permit or agree to the sale, holding separate, licensing or other disposition of, any assets of Parent, the Surviving Corporation or any other subsidiary of Parent or the Company, whether as a condition to obtaining any approval from, or to avoid potential litigation or administrative action by, a Governmental Entity or any other person or for any other reason.

6.7. Notification of Certain Matters; Litigation. Each party shall give prompt notice to the other parties of (a) the occurrence or non-occurrence of any event of which such party has knowledge the occurrence or non-occurrence of which would cause any representation or warranty made by such party in this Agreement to be untrue or inaccurate in any material respect at any time from the date hereof to the Effective Time, (b) any Offer Condition of which such party has knowledge is unsatisfied in any material respect as of any scheduled Expiration Date, and (c) any material failure of such party or any of its Representatives of which such party has knowledge to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties, the conditions to the obligations of the parties under this Agreement or the remedies available to the party receiving such notification. Without limiting the foregoing, the Company shall, within twenty-four (24) hours after it has notice of any of the following notify the Parent of (i) any notice or other communication from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated by this Agreement, (ii) any notice or other communication from any Governmental Entity in connection with the transactions contemplated by this Agreement, and (iii) any actions, suits, claims, investigations or proceedings instituted or threatened against the Company or any of its directors, officers or Affiliates, including by any stockholder of the Company, before any court or Governmental Entity, relating to or involving or otherwise affecting the Company or any Company Subsidiaries which, if pending on the date of this Agreement, would have been required to have been disclosed pursuant to this Agreement or relating to this Agreement or the transactions contemplated hereby, or seeking damages or discovery in connection with such transactions. The Company shall consult with the Parent regarding the defense or settlement of any such actions, suits, claims, investigations or proceedings and shall consider the Parent’s views with respect to such actions, suits, claims, investigations or proceedings.

(a) Parent agrees that any rights to indemnification or exculpation now existing in favor of the directors or officers of the Company and the directors or officers of each Company Subsidiary (the “Indemnified Parties” and, each, an “Indemnified Party”) as provided in their respective organizational documents, in effect as of the date hereof, with respect to matters occurring at or prior to the Acceptance Time shall survive the Merger and shall continue in full force and effect for a period of six (6) years after the Acceptance Time, and Parent guarantees any such obligations of the Surviving Corporation. During such period, Parent shall not, nor shall it permit the Surviving Corporation to, amend, repeal or otherwise modify such provisions for indemnification in any manner that would materially and adversely affect the rights thereunder of individuals who at any time on or prior to the Acceptance Time were directors or officers of the Company or directors or officers of any of Company Subsidiary in respect of actions or omissions occurring at or prior to the Acceptance Time (including, without

limitation, the transactions contemplated by this Agreement), unless such modification is required by Law; provided, however, that in the event any claim or claims are asserted or made either prior to the Acceptance Time or within such six (6) year period, all rights to indemnification in respect of any such claim or claims shall continue until disposition of any and all such claims.

(b) Subject to the next sentence, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, (i) maintain, at no expense to the beneficiaries, in effect for six (6) years from the Effective Time, the current policies of the directors’ and officers’ liability insurance maintained by the Company (the “Current D&O Insurance”) with respect to matters existing or occurring at or prior to the Effective Time (including the transactions contemplated by this Agreement), so long as the annual premium therefor would not be in excess of two hundred percent (200%) of the last annual premium paid prior to the Effective Time (such two hundred percent (200%), the “Maximum Premium”), or (ii) purchase a six (6) year extended reporting period endorsement with respect to the Current D&O Insurance (a “Reporting Tail Endorsement”) and maintain such endorsement in full force and effect for its full term, provided, however, that prior to the Surviving Corporation taking any actions in clauses (i) or (ii) above, the Parent shall be provided the opportunity to purchase, in lieu thereof, a substitute policy with the same coverage limits and substantially similar terms as in the Reporting Tail Endorsement proposed to be purchased by the Surviving Corporation. If the Company’s or the Surviving Corporation’s existing insurance expires, is terminated or canceled during such six (6) year period or exceeds the Maximum Premium, the Surviving Corporation shall obtain, and the Parent shall cause the Surviving Corporation to obtain, as much directors’ and officers’ liability insurance as can be obtained for the remainder of such period for an annualized premium not in excess of the Maximum Premium, on terms and conditions no less advantageous to the Indemnified Parties than the Company’s existing directors’ and officers’ liability insurance.

(c) The obligations under this Section 6.8 shall not be terminated or modified in such a manner as to adversely affect any indemnitee to whom this Section 6.8 applies without the consent of such affected indemnitee (it being expressly agreed that the indemnitees to whom this Section 6.8 applies shall be third party beneficiaries of this Section 6.8 and shall be entitled to enforce the covenants contained herein).

(a) Promptly upon the payment by Sub for any Shares accepted by Sub for payment pursuant to the Offer at the Acceptance Time, which Shares represent at least a majority of the issued and outstanding Shares pursuant to the Offer, Parent shall be entitled to designate such number of directors on the Company Board of Directors as will give Parent, subject to compliance with Section 14(f) of the Exchange Act, representation on the Company Board of Directors equal to at least that number of directors, rounded up to the next whole number, which is the product of (x) the total number of directors on the Company Board of Directors (giving effect to the directors elected pursuant to this sentence) multiplied by (y) the percentage that (I) such number of Shares so accepted for payment and paid for by Sub plus the number of Shares otherwise owned by Parent, Sub or any other subsidiary of Parent bears to (II) the number of such Shares outstanding, and the Company shall, at such time, cause Parent’s designees to be so elected; provided, however, that in the event that Parent’s designees are appointed or elected to

the Company Board of Directors, until the Effective Time, the Company Board of Directors shall have at least three (3) directors who are directors on the date of this Agreement and who are not officers of the Company (the “Independent Directors”); and provided, further, that, in such event, if the number of Independent Directors shall be reduced below three (3) for any reason whatsoever, any remaining Independent Directors (or Independent Director, if there shall be only one remaining) shall be entitled to designate persons to fill such vacancies who shall be deemed to be Independent Directors for purposes of this Agreement or, if no Independent Directors then remain, the other directors shall designate three persons to fill such vacancies who are not officers or affiliates of the Company, Parent or Sub, and such persons shall be deemed to be Independent Directors for purposes of this Agreement. At such time, the Company shall, upon Parent’s request, also cause persons elected or designated by Parent to constitute the same percentage (rounded up to the next whole number) as is on the Company Board of Directors of (i) each committee of the Company Board of Directors, (ii) each board of directors (or similar body) of each of the Company’s Subsidiaries, and (iii) each committee (or similar body) of each such board, in each case only to the extent required by applicable Law or the rules of any stock exchange on which the Shares are listed. Subject to applicable Law, the Company shall take all action requested by Parent necessary to effect any such election, including mailing to its stockholders the Information Statement containing the information required by Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder, and the Company shall make such mailing with the mailing of the Schedule 14D-9 (provided that Sub shall have provided to the Company on a timely basis all information required to be included in the Information Statement with respect to Sub’s designees). In connection with the foregoing, the Company shall promptly, at the option of Sub, either increase the size of the Company Board of Directors or obtain the resignation of such number of its current directors, or both, as is necessary to enable Sub’s designees to be elected or appointed to the Company Board of Directors as provided above.

(b) Notwithstanding anything in this Agreement to the contrary, if Parent’s designees constitute a majority of the Company Board of Directors after the Acceptance Time and prior to the Effective Time, then the affirmative vote of a majority of the Independent Directors (or if only one (1) exists, then the vote of such Independent Director) shall be required to (i) amend or terminate this Agreement by the Company, (ii) exercise or waive any of the Company’s rights, benefits or remedies hereunder, if such action would materially and adversely affect holders of Shares other than Parent or Sub, (iii) amend the certificate of incorporation or bylaws of the Company, or (iv) take any other action of the Company Board of Directors under or in connection with this Agreement or the transactions contemplated hereby; provided, however, that if there shall be no Independent Directors as a result of such persons’ deaths, disabilities or refusal to serve, then such actions may be effected by majority vote of the entire Company Board of Directors.

6.10. 401(k). Except with the prior written consent of Parent, during the period from the date of this Agreement to the Effective Time, the Company shall not (i) make any discretionary contribution to the Company’s 401(k) plan, other than employer matching contributions at the rate in effect immediately prior to the date of this Agreement, or (ii) make any required contribution to the Company’s 401(k) plan in Shares. If requested by Parent in writing at least 10 days prior to the scheduled expiration date of the Offer, the Company shall terminate the Company’s 401(k) plan immediately prior to the scheduled expiration date of the Offer.

(a) From the Effective Time through December 31, 2009, Parent shall or shall cause the Surviving Corporation to either (i) continue certain Plans, (ii) permit employees of the Company and any Company Subsidiary who remain in the employment with Parent or Surviving Corporation or their respective subsidiaries following the Effective Time (“Continuing Employees”) while they remain so employed by Parent or Surviving Corporation or their respective subsidiaries, and as applicable, their eligible dependents, to participate in the employee benefit plans, programs or policies (including without limitation any plan intended to qualify within the meaning of Section 401(a) of the Code and any severance, vacation, sick, personal time off plans or programs and excluding any equity compensation or bonus plans, programs, agreements or arrangements) of Parent or its Affiliates, or (iii) a combination of clauses (i) and (ii), in all cases, such employee benefit plans, programs or policies shall be substantially comparable in the aggregate to those provided to such employees immediately preceding the Effective Time (it being understood that (y) from the Effective Time through December 31, 2009, Parent shall provide to Company employees entitled to benefits under a Company bonus plan total cash compensation (base salary and bonus program) that is substantially comparable in the aggregate to the total cash compensation such employees had prior to the Effective Date and, for this purpose, the bonus compensation payable under the Company bonus plans for periods after the Effective Time is assumed to be payable at the target amount set forth in the applicable Company bonus plan and (z) any bonus compensation payable to Company employees shall be payable at such time as provided for in the applicable Company bonus plan).

(b) To the extent Parent elects to have Continuing Employees and their eligible dependents participate in its or its Affiliate’s employee benefit plans, program or policies following the Effective Time, Parent shall, or shall cause the Surviving Corporation or its subsidiaries to, recognize the prior service with the Company or any Company Subsidiary, including prior service with predecessor employers where such prior service is recognized by the Company and the Company Subsidiaries as of immediately prior to the Effective Time, of each Continuing Employee in connection with all employee benefit plans, programs or policies of Parent or its Affiliates in which Continuing Employees are eligible to participate for purposes of eligibility to participate, vesting and determination of level of benefits (but not (A) for purposes of vesting stock options and other equity awards, (B) for the purposes of benefit accruals under any defined benefit pension plan or (C) to the extent that such recognition would result in duplication of benefits).

(c) From and after the Effective Time, Parent shall, or shall cause the Surviving Corporation or its subsidiaries to, cause any pre-existing conditions or limitations and eligibility waiting periods under any group health plans of Parent or its Affiliates to be waived with respect to Continuing Employees and their eligible dependents to the extent such Continuing Employees and their eligible dependents were not subject to such preexisting conditions and limitations and eligibility waiting periods under the comparable Plans as of the time immediately preceding the Effective Time.

(d) No provision of this Agreement shall create any third party beneficiary rights in any employee, any beneficiary or dependents thereof, or any collective bargaining

representative thereof, with respect to the compensation, terms and conditions of employment and benefits that may be provided to any employee by Company, Parent or the Surviving Corporation or under any benefit plan which Company, Parent or Surviving Corporation may maintain.

7.1. Conditions to Obligations of Each Party to Effect the Merger. The respective obligations of each party to this Agreement to effect the Merger shall be subject to the satisfaction or written waiver at or prior to the Closing Date of the following conditions:

(a) Stockholder Approval. This Agreement shall have been adopted and the Merger thereby approved by the requisite vote of the holders of the Shares, to the extent required pursuant to the requirements of the certificate of incorporation and the DGCL.

(b) Statutes; Court Orders. No statute, rule, executive order or regulation shall have been enacted, issued, enforced or promulgated by any Governmental Entity which prohibits the consummation of the Merger, and there shall be no order or injunction of a court of competent jurisdiction in effect preventing consummation of the Merger.

(c) Consummation of Offer. The Shares validly tendered and not withdrawn pursuant to the Offer shall have been accepted for payment and paid for pursuant to the Offer and the terms of this Agreement; provided, however, that neither Parent nor Sub shall be entitled to assert the failure of this condition if, in breach of this Agreement or the terms of the Offer, Sub shall have failed to purchase any of the Shares validly tendered and not withdrawn pursuant to the Offer.

8.1. Termination. This Agreement may be terminated and the transactions contemplated hereby may be abandoned:

(a) By mutual written consent of Parent and the Company duly authorized by the Board of Directors of Parent and the Company Board of Directors at any time before the Effective Time, whether before or after stockholder adoption of this Agreement; or

(i) if at any time before the Effective Time, whether before or after stockholder adoption of this Agreement, a court of competent jurisdiction or other Governmental Entity shall have issued an order, decree or ruling or taken any other action, and such order, decree or ruling or other action shall have become final and non-appealable, or there shall exist any statute, rule or regulation, in each case, permanently restraining, enjoining or otherwise prohibiting (collectively, “Restraints”) the consummation of the Offer or the Merger; provided, however, that the party seeking to terminate this Agreement pursuant to this Section 8.1(b)(i) shall have used reasonable best efforts to prevent the entry of and to remove such Restraints in accordance with Section 6.6; or

(ii) if the Acceptance Time has not occurred by November 6, 2009 (the “Outside Date”); provided, however, that the right to terminate this Agreement pursuant to this Section 8.1(b)(ii) shall not be available to any party whose breach of this Agreement has been the principal cause of, or resulted in, the failure of the Acceptance Time to have occurred by such date; or

(c) By Parent if, prior to the Acceptance Time, there has been a breach by the Company of or inaccuracy in, any representation, warranty, covenant or agreement of the Company set forth in this Agreement, which breach or inaccuracy has resulted in the conditions set forth in paragraphs (c) or (e) of Annex I not being satisfied (and such breach or inaccuracy has not been cured or such condition has not been satisfied within twenty (20) days after the receipt of notice thereof or such breach or inaccuracy is not reasonably capable of being cured or such condition is not reasonably capable of being satisfied within such period); or

(d) By the Company if, prior to the Acceptance Time, there has been a breach by Parent or Sub of any representation, warranty, covenant or other agreement contained herein, or if a representation or warranty of Parent or Sub is no longer be true and correct, which situation in any case (i) would result in any of the representations and warranties of Parent and Sub set forth in this Agreement not being true and correct (without giving effect to any limitation as to “materiality” or “material adverse effect” or similar terms set forth therein) except where the failure to be so true and correct does not, and would not reasonably be expected to, prevent or materially delay or hinder Parent or Sub from performing in all material respects its obligations and covenants required to be performed by it under this Agreement and (ii) has not been cured within twenty (20) days following notice by the Company; or

(e) By Parent, at any time prior to the Acceptance Time, if (i) (A) the Company Board of Directors shall have (1) effected an Adverse Recommendation Change, (2) recommended to the Company’s stockholders an Acquisition Proposal, or publicly announced its intention to enter into an Alternative Acquisition Agreement, (3) failed to publicly reaffirm the Company Board Recommendation within four (4) business days of Parent’s request in writing that the Company Board Recommendation be publicly reaffirmed (provided that Parent is only allowed to make two (2) such reaffirmation requests prior to the Acceptance Time), or (4) failed to recommend against, or taken a neutral position with respect to, a tender or exchange offer related to an Acquisition Proposal in any position taken pursuant to Rules 14d-9 and 14e-2 under the Exchange Act; or (ii) after receiving an Acquisition Proposal, the Company shall have violated or breached in any material respect any of its obligations under Section 5.2 with respect to such Acquisition Proposal; or

(f) At any time prior to the Acceptance Time, by the Company, if the Company has received a Superior Proposal, which, after giving effect to all of the adjustments that may be offered by Parent pursuant to Section 5.2, the Company Board of Directors determines in good faith (after consultation with its financial advisors) continues to constitute a Superior Proposal, provided the Company shall not have violated or breached in any material respect any of its obligations under Section 5.2; or

(g) By Parent, if upon a vote at a duly held meeting to obtain the Company Stockholder Approval, such approval is not obtained, provided, however, that the Parent may not terminate this Agreement under this Section 8.1(g) if the Shares owned by the Parent or any of its subsidiaries shall not have been voted in favor of adopting this Agreement; or

(h) By the Company, prior to commencement of the Offer, if Sub has not commenced the Offer by May 21, 2009; provided, however, that the Company may not terminate this Agreement pursuant to this Section 8.1(h) if such failure to commence the Offer has resulted from the breach of this Agreement by the Company or if the Company has not provided Sub with a Schedule 14D-9 the Company is prepared to file, without further revisions, upon commencement of the Offer; or

(i) By Parent, at any time prior to the Acceptance Time, if there shall have occurred a Company Material Adverse Effect.

(a) Any termination of this Agreement under Section 8.1 hereof will be effective immediately upon the delivery of a written notice of the terminating party to the other party hereto and, if then due, payment of the Termination Fee. In the event of termination of this Agreement as provided in Section 8.1 hereof, this Agreement shall forthwith become null and void and be of no further force or effect and there shall be no liability on the part of Parent, Sub or the Company (or any of their respective directors, officers, employees, stockholders, agents or representatives), except as set forth in the last sentence of Section 6.4, SECTION 8 and SECTION 9, each of which shall remain in full force and effect and survive any termination of this Agreement; provided, however, that (i) nothing herein shall relieve any party from liability for fraud or intentional breach of any of its representations, warranties, covenants or agreements set forth in this Agreement (it being understood that the failure of Parent or Sub to accept for payment and pay for the Shares validly tendered and not withdrawn pursuant to the Offer promptly following the Expiration Date in the event that all Offer Conditions have been satisfied or, to the extent permitted, waived, as of the Expiration Date shall be deemed an intentional breach by Parent and Sub pursuant to this Agreement), and (ii) no termination of this Agreement shall in any way affect the parties’ rights or obligations with respect to any Shares accepted for payment pursuant to the Offer prior to such termination.

(b) If Parent shall have terminated this Agreement pursuant to Section 8.1(e), the Company shall promptly pay Parent a termination fee (the “Termination Fee”) of $17,000,000, but in no event later than two (2) business days after the date of receipt of Parent’s termination notice. If the Company intends to terminate this Agreement pursuant to Section 8.1(f), it shall, substantially concurrent with such termination, pay Parent the Termination Fee. If Parent terminates this Agreement pursuant to Section 8.1(c) due to an intentional or knowing material breach by the Company of a covenant or agreement of the Company set forth in this Agreement, and prior to such time an Acquisition Proposal has been made that has not been withdrawn prior to the time of such termination, then the Company shall pay Parent the Termination Fee concurrent with the consummation of any Acquisition Proposal that is consummated prior to the first anniversary of the date of such termination or for which the definitive written agreement providing for the consummation of such Acquisition Proposal has been executed no later than the first anniversary of the date of such termination (it being understood that for purposes of this Section 8.2(b), the references to “fifteen percent (15%)” in

the definition of “Acquisition Proposal” shall be replaced with “fifty percent (50%).” All amounts due hereunder shall be payable by wire transfer in immediately available funds to such account as Parent may designate in writing to the Company. If the Company fails to promptly make any payment required under this Section 8.2(b) and Parent commences a suit to collect such payment, the Company shall indemnify Parent for its fees and expenses (including attorneys fees and expenses) incurred in connection with such suit and shall pay interest on the amount of the payment at the prime rate of Bank of America (or its successors or assigns) in effect on the date the payment was payable pursuant to this Section 8.2(b).

8.3. Fees and Expenses. Except as set forth in Section 8.2, all fees, costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such expenses whether or not the Merger is consummated.

8.4. Amendment. Subject to applicable Law and as otherwise provided in the Agreement, this Agreement may be amended, modified and supplemented in any and all respects, whether before or after any vote of the stockholders of the Company contemplated hereby, by written agreement of the parties hereto, by action taken by their respective Boards of Directors, but after the purchase of Shares pursuant to the Offer, no amendment shall be made which decreases the Merger Consideration and, after the approval of this Agreement by the stockholders, no amendment shall be made which by Law requires further approval by such stockholders without obtaining such further approval. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

8.5. Waiver. At any time prior to the Effective Time, either party hereto may (a) extend the time for the performance of any of the obligations or other acts of the other party hereto or (b) waive compliance with any of the agreements of the other party or any conditions to its own obligations, in each case only to the extent such obligations, agreements and conditions are intended for its benefit; provided, that any such extension or waiver shall be binding upon a party only if such extension or waiver is set forth in a writing executed by such party.

9.1. No Survival. None of the representations and warranties contained herein shall survive the Effective Time.

9.2. Notices. Any notice or other communication required or permitted hereunder shall be in writing and shall be deemed given when delivered in person, by overnight courier, by facsimile transmission (with receipt confirmed by telephone or by automatic transmission report) or two (2) business days after being sent by registered or certified mail (postage prepaid, return receipt requested), as follows:

Any party may by notice given in accordance with this Section 9.2 to the other parties designate updated information for notices hereunder.

9.3. Entire Agreement. This Agreement (including the Schedules, Annexes and Exhibits hereto and the documents and instruments referred to herein) contains the entire agreement among the parties with respect to the Offer, the Merger and related transactions, and supersedes all prior agreements, written or oral, among the parties with respect thereto, other than the Confidentiality Agreement and the tender and voting agreements with the Principal Stockholders.

9.4. Governing Law. This Agreement and all actions arising under or in connection therewith shall be governed by and construed in accordance with the Laws of the State of Delaware, regardless of the Laws that might otherwise govern under applicable principles of conflicts of law thereof, provided, however, that the Laws of the respective jurisdictions of incorporation of each of the parties shall govern the relative rights, obligations, powers, duties and other internal affairs of such party and its board of directors.

(a) This Agreement shall not be assigned by any of the parties hereto (whether by operation of Law or otherwise) without the prior written consent of the other parties, except that Sub may assign, in its sole discretion and without the consent of any other party, any or all of its rights, interests and obligations hereunder to (i) Parent, (ii) to Parent and one or more direct or indirect wholly-owned subsidiaries of Parent, (iii) to one or more direct or indirect wholly-owned subsidiaries of Parent or (iv) any direct or indirect holder of five percent (5%) or more of the capital stock of Parent or any subsidiary thereof (each, an “Assignee”). Any such Assignee may thereafter assign, in its sole discretion and without the consent of any other party, any or all of its rights, interests and obligations hereunder to one or more additional Assignees; provided, however, that in connection with any assignment to an Assignee, Parent and Sub (and the assignor, if applicable) shall agree to remain liable for the performance by Parent and Sub (and such assignor, if applicable) of their obligations hereunder, including the obligation to pay in full for all Shares validly tendered into the Offer and the Merger Consideration, subject to the terms and conditions of the Offer and this Agreement; and provided, further, that in connection with any assignment under this Section 9.5(a) that would increase the amount, if any, required to be deducted or withheld from amounts payable or otherwise deliverable pursuant to this Agreement to the holders or former holders of Shares, Company Options or Company RSUs under the Tax Law of a jurisdiction outside the United States, such assignment shall be null and void unless Parent, Sub and the applicable assignee specifically agree that the last sentence of Section 2.6 shall also apply with respect to such increase such that each holder or former holder of Shares, Company Options or Company RSUs shall receive the same amount that would otherwise have been received if no such assignment been made. Subject to the preceding sentence, but without relieving any party hereto of any obligation hereunder, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns.

(b) Other than Section 6.8, which shall confer third party beneficiary rights to the parties identified therein, nothing in this Agreement, express or implied, is intended to or shall confer upon any person other than Parent, Sub and the Company and their respective successors and permitted assigns any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

9.6. Counterparts and Signature. This Agreement may be executed in two or more counterparts (including by facsimile or by an electronic scan delivered by electronic mail), each of which shall be deemed an original but all of which together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the parties hereto and delivered to the other parties, it being understood that all parties need not sign the same counterpart. This Agreement may be executed and delivered by facsimile or by an electronic scan delivered by electronic mail.

9.7. Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement shall remain in full force and effect. Any provision of this Agreement held invalid or unenforceable only in part or degree shall remain in full force and effect to the extent not held invalid or unenforceable. The parties further agree to replace such invalid or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable provision.

9.8. Submission to Jurisdiction; Waiver. Each of the Company, Parent and Sub irrevocably agrees that any legal action or proceeding with respect to this Agreement or the transactions contemplated hereby or for recognition and enforcement of any judgment in respect hereof brought by the other party hereto or its successors or assigns shall be brought and determined in the state courts of the State of Delaware or, the United States District Court for the District of Delaware, and each of the Company, Parent and Sub hereby irrevocably submits with regard to any action or proceeding for itself and in respect to its property, generally and unconditionally, to the exclusive jurisdiction of the aforesaid courts. Each of the Company, Parent and Sub hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement, (a) any claim that it is not personally subject to the jurisdiction of the above-named courts for any reason other than the failure to lawfully serve process, (b) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise), and (c) to the fullest extent permitted by applicable Law, that (i) the suit, action or proceeding in any such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper and (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

9.9. Time is of the Essence. Time is of the essence with respect to the performance of this Agreement.

9.10. Parent Guarantee. Parent shall cause Sub to comply in all respects with each of its representations, warranties, covenants, obligations, agreements and undertakings pursuant to or otherwise in connection with this Agreement, the Offer, the Merger and the other transactions contemplated by this Agreement. As a material inducement to the Company’s willingness to enter into this Agreement and perform its obligations hereunder, Parent hereby unconditionally guarantees full performance and payment by Sub of each of its covenants, obligations and undertakings pursuant to or otherwise in connection with this Agreement, the Offer, the Merger and the other transactions contemplated by this Agreement and hereby represents, acknowledges and agrees that any breach of, or other failure to perform, any such representation, warranty, covenant, obligation, agreement or undertaking of Sub shall also be deemed to be a breach or failure to perform by Parent, and the Company shall have the right, exercisable in its sole discretion, to pursue any and all available remedies it may have arising out of any such breach or nonperformance directly against either or both of Parent and Sub in the first instance.

9.11. Enforcement. The parties recognize and agree that if for any reason any of the provisions of this Agreement are not performed in accordance with their specific terms or are otherwise breached, immediate and irreparable harm or injury would be caused for which money damages would not be an adequate remedy. Accordingly, each party agrees that in addition to other remedies the other party shall be entitled to an injunction without posting a bond or other undertaking restraining any violation or threatened violation of the provisions of this Agreement. In the event that any action shall be brought in equity to enforce the provisions of the Agreement, no party shall allege, and each party hereby waives the defense, that there is an adequate remedy at Law.

(a) Except where expressly stated otherwise in this Agreement, the following rules of interpretation apply to this Agreement: (i) “either” and “or” are not exclusive and “include”, “includes” and “including” are not limiting; (ii) “hereof”, “hereto”, “hereby”, “herein” and “hereunder” and words of similar import when used in this Agreement refer to this Agreement as a whole and not to any particular provision of this Agreement; (iii) “date hereof” refers to the date set forth in the initial caption of this Agreement; (iv) “extent” in the phrase “to the extent” means the degree to which a subject or other thing extends, and such phrase does not mean simply “if”; (v) descriptive headings, the table of defined terms and the table of contents are inserted for convenience only and do not affect in any way the meaning or interpretation of this Agreement; (vi) definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms; (vii) references to a person are also to its permitted successors and assigns; (viii) references to an “Article”, “Section”, “Exhibit”, “Annex” or “Schedule” refer to an Article or Section of, or an Exhibit, Annex or Schedule to, this Agreement; (ix) references to “$” or otherwise to dollar amounts refer to the lawful currency of the United States; (x) references to a federal, state, local or foreign statute or Law include any rules, regulations and delegated legislation issued thereunder; and (xi) references to a communication by a regulatory agency include a communication by the staff of such regulatory agency. The language used in this Agreement shall be deemed to be the language chosen by the parties hereto to express their mutual intent, and no rule of strict construction shall be applied against any party hereto. No summary of this Agreement prepared by any party shall affect the meaning or interpretation of this Agreement. The parties hereto agree that they have been represented by counsel during the negotiation and execution of this Agreement and, therefore, waive the application of any Law, regulation, holding or ruling of construction providing that ambiguities in an agreement or other document shall be construed against the party drafting such agreement or document.

(b) The following definitions apply to this Agreement: (i) references to the “Company’s knowledge” and words of similar import shall mean the actual knowledge of each of Brian Farley and Peter Osborne, after reasonable inquiry of the individuals set forth on Schedule 9.12(b), and the actual knowledge of each of the individuals set forth on Schedule 9.12(b); (ii) references to the number of Shares then outstanding “on a fully diluted basis” means the number of Shares then outstanding, together with the Shares pursuant to Company RSUs and Shares that the Company may be required to issue pursuant to Company Options that are outstanding at that date, under the Company Stock Plans, whether or not vested and whether or not their exercise prices are less than the Offer Price; (iii) the term “Governmental Entity” shall mean any foreign or domestic arbitrator, court, nation, government, any state or other political subdivision thereof and any entity exercising executive, legislative, judicial regulatory or administrative functions of, or pertaining to, government; and (iv) the term “person” shall mean any individual, corporation (including any non-profit corporation), general partnership, limited partnership, limited liability partnership, joint venture, estate, trust, company (including any limited liability company or joint stock company), firm or other enterprise, association, organization, entity or Governmental Entity.

9.13. No Waiver; Remedies Cumulative. No failure or delay on the part of any party hereto in the exercise of any right hereunder will impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor will any single or partial exercise of any such right preclude other or further exercise thereof or of any other right. All rights and remedies existing under this Agreement are cumulative to, and not exclusive to, and not exclusive of, any rights or remedies otherwise available.

9.14. Waiver of Jury Trial. EACH OF PARENT, COMPANY AND SUB HEREBY IRREVOCABLY WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED IN CONTRACT, TORT OR OTHERWISE) ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY RELATED DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENT OR ACTION RELATED HERETO OR THERETO.

IN WITNESS WHEREOF, the parties have executed this Agreement and Plan of Merger under seal as of the date first stated above.

Notwithstanding any other provisions of the Offer, and in addition to (and not in limitation of) Sub’s rights to extend and amend the Offer at any time in its sole discretion (subject to the provisions of the Merger Agreement), Sub shall not be required to accept for payment or, subject to any applicable rules and regulations of the SEC, including Rule 14e-l(c) under the Exchange Act (relating to Sub’s obligation to pay for or return tendered Shares promptly after termination or withdrawal of the Offer), pay for, and may delay the acceptance for payment of or, subject to the restriction referred to above, the payment for, any validly tendered Shares if (i) immediately prior to the expiration of the Offer (as extended in accordance with the Merger Agreement), the number of Shares validly tendered (including by guaranteed delivery) and not validly withdrawn, together with any Shares beneficially owned by the Parent or any subsidiary of the Parent, does not equal at least a majority of the Shares then outstanding on a fully diluted basis (the “Minimum Condition”); (ii) immediately prior to the expiration of the Offer (as extended in accordance with the Merger Agreement), any waiting period (and any extensions thereof) and any approvals or clearances applicable to the Offer or the consummation of the Merger under the HSR Act or any provision under comparable applicable Laws of those foreign jurisdictions set forth on Annex I-A shall not have expired, or been terminated or obtained, as applicable; or (iii) any of the following events shall occur and be continuing immediately prior to the expiration of the Offer (as extended in accordance with the Merger Agreement):

(a) there shall be pending any suit, action or proceeding by any Governmental Entity (i) seeking to prohibit or impose any material limitations on Parent’s or Sub’s ownership or operation (or that of any of their respective Subsidiaries) of all or any material portion of the Company’s or the Company’s Subsidiaries’ businesses or assets, taken as a whole, or to compel Parent or Sub or their respective Subsidiaries to dispose of or hold separate any material portion of the business or assets of the Company or the Company Subsidiaries or Parent, Sub and their Affiliates, (ii) seeking to prohibit or make illegal the making or consummation of the Offer or the Merger or the performance of any of the other transactions contemplated by the Merger Agreement, (iii) seeking to impose material limitations on the ability of Sub, or render Sub unable, to accept for payment, pay for or purchase some or all of the Shares pursuant to the Offer or the Merger, (iv) seeking to impose material limitations on the ability of Sub or Parent effectively to exercise full rights of ownership of the Shares, including, without limitation, the right to vote the Shares purchased by it on all matters properly presented to the Company’s stockholders, or (v) seeking to require divestiture by Parent or any of its Subsidiaries of any Shares;

(b) there shall be any statute, rule, regulation, judgment, order or injunction enacted, entered, enforced, promulgated or deemed applicable, pursuant to an authoritative interpretation by or on behalf of a Government Entity, to the Offer, the Merger or any other transaction contemplated hereby, or any other action shall be taken by any Governmental Entity, that would reasonably be expected to result, directly or indirectly, in any of the consequences referred to in clauses (i) through (v) of paragraph (a) of this Annex I;

(c) any of the representations and warranties of the Company contained in the Merger Agreement shall not be true and correct (1) as of the date of the Merger Agreement and (2) as of the Acceptance Time except in the case of each of clauses “(1)” and “(2),” (w) for representations and warranties that relate to a specific date or time (which need only be true and correct as of such date or time), (x) any representation or warranty of the Company contained in Section 3.2, the first sentence of Section 3.8 and the third sentence of Section 3.5 shall be deemed untrue if it fails to be true and correct in all respects, (y) any representation or warranty of the Company contained in Section 3.3 or in Section 3.8 (other than the first sentence thereof) shall be deemed untrue if it fails to be true and correct in all material respects (it being understood that the representations and warranties in Sections 3.3(a) and 3.3(b) shall be deemed to be materially inaccurate if the Company’s actual fully diluted capitalization exceeds by more than seventeen thousand two hundred (17,200) shares the Company’s fully diluted capitalization set forth in Sections 3.3(a) and 3.3(b)), and (z) for any representation or warranty (other than any representation or warranty referred to in clauses (x) or (y) above), where the failure to be so true and correct, individually or in the aggregate, does not have or would not reasonably be expected to have a Company Material Adverse Effect (without giving effect to the words “materially” or “material” or to any qualification based on the defined term “Company Material Adverse Effect” embedded in any such representation or warranty);

(d) since the date of this Agreement, there shall have occurred any events or changes which have had, or which are reasonably likely to have or constitute, individually or in the aggregate, a Company Material Adverse Effect;

(e) the Company shall have breached or failed to perform or to comply in any material respect with any agreement, obligation or covenant to be performed or complied with by it under the Merger Agreement and such breach or failure to perform or to comply shall not have been cured by the Company;

(f) Parent and Sub shall have failed to receive a certificate executed by the Company’s Chief Executive Officer or President on behalf of the Company, dated as of the then-scheduled expiration of the Offer, to the effect that the conditions set forth in paragraphs (c), (d) and (e) of this Annex I have not occurred; or

(g) the Merger Agreement shall have been terminated in accordance with its terms.

The foregoing conditions are for the sole benefit of Parent and Sub, may be asserted by Parent or Sub regardless of the circumstances giving rise to such condition, and may be waived by Parent or Sub in whole or in part at any time and from time to time and in the sole discretion of Parent or Sub, subject in each case to the terms of the Merger Agreement. The failure by Parent or Sub at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right and, each such right shall be deemed an ongoing right which may be asserted at any time and from time to time.

The term “Merger Agreement” shall be deemed to refer to the Agreement to which this Annex I is annexed. The other capitalized terms used in this Annex I shall have the meanings set forth in the Merger Agreement.

THIS TENDER AND VOTING AGREEMENT (this “Agreement”) dated May 7, 2009, is entered into between Covidien Group S.a.r.l., a Luxembourg company (“Parent”), Covidien Delaware Corp., a Delaware corporation and direct or indirect wholly owned subsidiary of Parent (“Sub”), and , (“Stockholder”), with respect to (a) the shares of common stock, par value $0.001 per share (the “Shares”), of VNUS Medical Technologies, Inc., a Delaware corporation (the “Company”), (b) all securities exchangeable, exercisable or convertible into Shares, and (c) any securities issued or exchanged with respect to such Shares upon any recapitalization, reclassification, merger, consolidation, spin-off, partial or complete liquidation, stock dividend, split-up or combination of the securities of the Company or upon any other change in the Company’s capital structure, in each case whether now owned or hereafter acquired by the Stockholder (collectively, the “Securities”).

WHEREAS, Parent, Sub and the Company have entered into an Agreement and Plan of Merger dated as of the date hereof (as the same may be amended or supplemented, other than to lower the price to be paid in the Offer or Merger, the “Merger Agreement”) pursuant to which Sub has agreed to make a cash tender offer as described therein and thereafter merge with and into the Company (the “Merger”) with the result that the Company becomes a wholly owned subsidiary of Parent;

WHEREAS, as of the date hereof, Stockholder is the record or beneficial owner and has the power to dispose of the Securities set forth on Schedule I hereto and has the power to vote the Shares set forth thereon, except as otherwise set forth on Schedule I;

WHEREAS, Parent and Sub desire to enter into this Agreement in connection with their efforts to consummate the acquisition of the Company;

[For Chief Executive Officer only] WHEREAS, Stockholder, as an executive and stockholder of the Company, has obtained extensive and valuable knowledge, expertise and confidential information concerning the Business (as defined below), and has valuable business contacts with clients and potential clients of the Business and with professionals in the industry in which the Company operates; the Company’s reputation and goodwill are an integral part of the Company’s business success throughout the areas where it conducts the Business and if Stockholder deprives Parent or Sub of any of the Company’s goodwill or in any manner uses its reputation and goodwill in competition with Parent, Sub or the Surviving Corporation, Parent or Sub will be deprived of the benefits it has bargained for pursuant to this Agreement and the Merger Agreement; since Stockholder has the ability to compete with Parent, Sub and the

Surviving Corporation in the operation of the Business, Parent and Sub therefore desire that Stockholder enter into this Agreement; and but for Stockholder’s entry into this Agreement, Parent and Sub would not have entered into the Merger Agreement; and

WHEREAS, capitalized terms used in this Agreement and not defined have the meaning given to such terms in the Merger Agreement.

NOW, THEREFORE, in contemplation of the foregoing and in consideration of the mutual agreements, covenants, representations and warranties contained herein and intending to be legally bound hereby, the parties hereto agree as follows:

1.1 Lock-Up. Subject to Section 1.5, except as contemplated by the Merger Agreement, Stockholder hereby covenants and agrees that between the date hereof and the Termination Date, Stockholder will not (a) directly or indirectly, sell, transfer, assign, pledge, hypothecate, tender, encumber or otherwise dispose of or limit its right to vote in any manner any of the Securities, or agree to do any of the foregoing, or (b) take any action which would have the effect of preventing or disabling Stockholder from performing its obligations under this Agreement. Notwithstanding the foregoing, in connection with any transfer not involving or relating to any Acquisition Proposal (as defined in the Merger Agreement), Stockholder may transfer any or all of the Securities as follows: (i) in the case of a Stockholder that is an entity, to any subsidiary, partner or member of Stockholder, and (ii) in the case of an individual Stockholder, to Stockholder’s spouse, ancestors, descendants or any trust for any of their benefits or to a charitable trust; provided, however, that in any such case, prior to and as a condition to the effectiveness of such transfer, (A) each person to which any of such Securities or any interest in any of such Securities is or may be transferred (1) shall have executed and delivered to Parent and Sub a counterpart to this Agreement pursuant to which such person shall be bound by all of the terms and provisions of this Agreement, and (2) shall have agreed in writing with Parent and Sub to hold such Securities or interest in such Securities subject to all of the terms and provisions of this Agreement, and (B) this Agreement shall be the legal, valid and binding agreement of such person, enforceable against such person in accordance with its terms.

1.2 No Solicitation. Between the date hereof and the Termination Date, neither the Stockholder nor any director, officer, agent, representative, employee, affiliate, advisor, attorney, accountant or associate of Stockholder or those of its subsidiaries (collectively, “Representatives”) shall, directly or indirectly, take any action that the Company is prohibited from taking pursuant to Section 5.2 of the Merger Agreement.

1.3 Certain Events. This Agreement and the obligations hereunder will attach to the Securities and will be binding upon any person to which legal or beneficial ownership of any or all of the Securities passes, whether by operation of Law or otherwise, including without limitation, the Stockholder’s successors or assigns. This Agreement and the obligations hereunder will also attach to any additional Shares or other Securities of the Company issued to or acquired by the Stockholder.

(a) The Stockholder has revoked or terminated any proxies, voting agreements or similar arrangements previously given or entered into with respect to the Securities and hereby irrevocably appoints Parent as proxy for Stockholder to vote the Shares as to which Stockholder has voting power for Stockholder and in Stockholder’s name, place and stead, at any annual or special meeting of the stockholders of the Company, as applicable, or at any adjournment thereof, whether before or after the Acceptance Date (as defined in the Merger Agreement), solely for the adoption of the Merger Agreement and the approval of the Merger. Parent hereby acknowledges that the proxy granted hereby shall not be effective for any other purpose. The parties acknowledge and agree that neither Parent, nor Parent’s successors, assigns, subsidiaries, divisions, employees, officers, directors, stockholders, agents and affiliates shall owe any duty to, whether in law or otherwise, or incur any liability of any kind whatsoever, including without limitation, with respect to any and all claims, losses, demands, causes of action, costs, expenses (including reasonable attorney’s fees) and compensation of any kind or nature whatsoever to the Stockholder in connection with or as a result of any voting by Parent of the Shares subject to the irrevocable proxy hereby granted to Parent at any annual or special meeting of the stockholders of the Company for the purpose set forth herein.

(b) Notwithstanding the foregoing grant to Parent of the irrevocable proxy, if Parent elects not to exercise its rights to vote the Shares pursuant to the irrevocable proxy, Stockholder agrees to vote the Shares during the term of this Agreement in favor of or give its consent to, as applicable, a proposal to adopt the Merger Agreement and thereby approve the Merger at any annual or special meeting of the stockholders of the Company.

(c) This irrevocable proxy shall not be terminated by any act of the Stockholder or by operation of law, whether by the death or incapacity of the Stockholder or by the occurrence of any other event or events (including, without limiting the foregoing, the termination of any trust or estate for which Stockholder is acting as a fiduciary or fiduciaries or the dissolution or liquidation of any corporation or partnership). If between the execution hereof and the Termination Date, Stockholder should die or become incapacitated, or if any trust or estate holding the Securities should be terminated, or if any corporation or partnership holding the Securities should be dissolved or liquidated, or if any other such similar event or events shall occur before the Termination Date, certificates representing the Securities shall be delivered by or on behalf of Stockholder in accordance with the terms and conditions of the Merger Agreement and this Agreement, and actions taken by Parent hereunder shall be as valid as if such death, incapacity, termination, dissolution, liquidation or other similar event or events had not occurred, regardless of whether or not Parent has received notice of such death, incapacity, termination, dissolution, liquidation or other event.

1.5 Tender of Securities. Stockholder agrees, in exchange for the consideration described in the Merger Agreement, to (a) tender any Shares owned of record by Stockholder or for which Stockholder has sole dispositive power prior to the Commencement Date to Sub in the Offer not later than five (5) business days following the Commencement Date, and (b) tender any Shares acquired by Stockholder after the Commencement Date to Sub in the Offer not later than the earlier of (i) five (5) business days following the acquisition of such Shares or (ii) the Acceptance Date, and Stockholder shall not withdraw any Shares so tendered

under clauses (a) and (b) above unless the Offer is terminated or this Agreement shall have been terminated in accordance with its terms; provided, however, that Stockholder shall not be required, for purposes of this Agreement, to exercise any unexercised Company Options held by such Stockholder or tender any Shares granted to such Stockholder under an employee benefit plan of the Company which are unvested and subject to any risk of forfeiture, and Stockholder shall not have any obligation under this Section 1.5 to tender such Stockholder’s Shares into the Offer if that tender could cause such Stockholder to incur liability under Section 16(b) of the Exchange Act.

(a) On the terms and subject to the conditions set forth herein, Stockholder hereby grants to Parent an irrevocable option (the “Option”) to purchase all of the right, title and interest of Stockholder in and to Stockholder’s Securities with a price per share equal to the Offer Price. Parent may exercise the Option in whole, but not in part, if, but only if, (i) Sub has acquired Shares pursuant to the Offer and (ii) Stockholder has failed to tender into the Offer any Shares or shall have withdrawn the tender of any Shares into the Offer in breach of this Agreement. Parent may exercise the Option at any time within the sixty (60) days following the date when such Option first becomes exercisable.

(b) In the event that Parent is entitled to and wishes to exercise the Option, Parent shall send a written notice to Stockholder specifying the place and the date for the closing of such purchase, which date shall be not more than sixty (60) days after the date of such notice; provided that in the event that prior notification to, or approval of, any Governmental Entity is required in connection with the exercise of the Option or there shall be in effect any preliminary or final injunction or other order issued by any Governmental Entity prohibiting the exercise of the Option, the period of time during which the date of the closing may be fixed shall be extended until the tenth (10th) day following the last date on which all required approvals shall have been obtained, all required waiting periods shall have expired or been terminated and any such prohibition shall have been vacated, terminated or waived.

(c) At the closing of the purchase of Stockholder’s Securities pursuant to exercise of the Option, simultaneously with the payment by Parent of the purchase price for Stockholder’s Securities, such Stockholder shall deliver, or cause to be delivered, to the Sub certificates representing Securities duly endorsed to Parent or accompanied by stock powers or other transfer documents duly executed by the Company in blank, together with any necessary stock transfer stamps properly affixed, free and clear of all Encumbrances.

(d) Parent, Sub or the Company, as applicable, shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Section 1.6 to a holder of Securities such amounts as are required to be withheld under the Code or the Treasury Regulations thereunder or any other Tax Law. To the extent that amounts are so deducted and withheld, and such deduction and withholding would have been required were Parent incorporated or organized in the United States or a subdivision thereof, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Securities in respect of which such deduction and withholding was made. To the extent any amounts are required to be deducted and withheld under the Tax Law of a jurisdiction outside the United

States, and such deduction would not have been required were Parent incorporated or organized in the United States or a subdivision thereof, additional amounts shall be paid as necessary to ensure that the Stockholder receives the same amount that would otherwise have been received as if no such deduction and withholding had been made.

1.7 Public Announcement. Stockholder shall consult with Parent before issuing any press releases or otherwise making any public statements with respect to the transactions contemplated herein and shall not issue any such press release or make any such public statement without the approval of Parent, except as may be required by Law, including any filings with the Securities and Exchange Commission (the “SEC”) pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”). This Section 1.7 shall terminate and be null and void upon the earlier of (a) the Termination Date and (b) consummation of the Merger.

1.8 Disclosure. Stockholder hereby authorizes Parent and Sub to publish and disclose in any announcement or disclosure required by the SEC, The Nasdaq Stock Market or any other national securities exchange and in the Offer Documents and, if necessary, the Proxy Statement (including all documents and schedules filed with the SEC in connection with either of the foregoing), Stockholder’s identity and ownership of the Securities and the nature of Stockholder’s commitments, arrangements and understandings under this Agreement. Parent and Sub hereby authorize Stockholder to make such disclosure or filings as may be required by the SEC or The Nasdaq Stock Market or any other national securities exchange.

(a) Stockholder agrees for a period of three (3) years immediately following the Closing Date, Stockholder will not, directly or indirectly, own, manage, control, be employed by, operate, perform, have any interest in or otherwise be engaged in or concerned with any business that develops, manufactures, sells, markets or distributes, anywhere in the world, products or devices intended for the treatment of venous reflux disease that compete with any products or devices being developed, manufactured, sold, marketed or distributed by or on behalf of the Company as of the date hereof, including without limitation any such products or devices that are under development as of the date hereof but not yet offered for sale by the Company (the “Business”); provided, however, that (i) Stockholder shall be permitted to work for a division, entity, or subgroup of any of such competing business so long as such division, entity, or subgroup does not engage in a business (including, without limitation, development, manufacturing, marketing, sales or technical or sales support) that makes such entity compete with the Business and Stockholder does not facilitate, directly or indirectly, competition with the Business, and (ii) Stockholder may also receive and hold in such situation equity in such entity that he obtains in connection with such service on the same basis as other employees similarly situated to Stockholder; provided, further, that Stockholder shall not be prohibited from owning not more than 1% of any class of securities of any entity, whether such securities are publicly traded on a recognized securities exchange or are privately held. Stockholder expressly acknowledges that the foregoing geographic area is reasonable and necessary to protect the legitimate business interests of the Company, especially given the special information and knowledge held by Stockholder. Further, Stockholder acknowledges that the Company would

not proceed with the transactions contemplated by the Merger Agreement without receiving the full scope of the protections provided for hereunder and that any lesser geographic restriction would not adequately protect the Company. Stockholder also agrees that for such period, the Stockholder shall not in any way make any negative or disparaging statements or communications about the Surviving Corporation, its products or business); conversely, the Surviving Corporation, Parent and the officers thereof agree to not make any negative or disparaging comments or communications regarding Stockholder for such period.

(b) Stockholder agrees that for a period of two (2) years following the Closing Date, Stockholder will not, directly or indirectly, induce any employee to terminate his or her employment with the Surviving Corporation or hire any such employee, provided, however, the foregoing shall not prohibit Stockholder from making general solicitations through advertising, internet postings or other similar solicitations not targeted at employees of the Surviving Corporation, or from hiring any employee of the Surviving Corporation who responds to any such general solicitation without encouragement or inducement by the Stockholder.

(c) Stockholder acknowledges that the restrictions on his activities under this Agreement are necessary for the reasonable protection of Parent and Sub and constitute a material inducement to Parent and Sub entering into and performing under the Merger Agreement. Stockholder further acknowledges, stipulates and agrees that a breach of any of such obligations and agreements will result in irreparable harm and continuing damage to Parent and Sub for which there will be no adequate remedy at law and further agrees that in the event of any breach of said obligations and agreements, Parent, Sub and their successors and assigns will be entitled to injunctive relief and to such other relief as is proper under the circumstances.

(d) It is the desire and intent of the parties to this Agreement that the provisions of this Section 1.9 shall be enforced to the fullest extent permissible under the Laws and public policies applied in each jurisdiction in which enforcement is sought. If any covenant set forth in this Section 1.9 is determined by any court to be unenforceable by reason of its extending for too great a period of time or over too great a geographic area, or by reason of its being too extensive in any other respect, such covenant shall be interpreted to extend only for the longest period of time and over the greatest geographic area, and to otherwise have the broadest application as shall be enforceable.

2. Representations and Warranties of Stockholder. Stockholder hereby represents and warrants to Parent and Sub, as of the date hereof and as of the date Sub purchases Shares pursuant to the Offer, that:

2.1 Ownership. As of the date hereof, Stockholder holds of record or beneficially the Securities set forth on Schedule I, in each case, except as set forth on Schedule I, free and clear of all liabilities, claims, liens, options, proxies, charges, participations and encumbrances of any kind or character whatsoever, other than those arising under the securities laws or under the Company’s governance documents (collectively, “Liens”). At the time Sub purchases Shares pursuant to the Offer, Stockholder will transfer and convey to Sub good and marketable title to the Shares included in the Securities, free and clear of all Liens created by or arising through Stockholder.

2.2 Authorization. Stockholder has all requisite power and authority to execute and deliver this Agreement and to consummate the transactions contemplated hereby and has sole voting power and sole power of disposition, with respect to the Securities with no restrictions on its voting rights or rights of disposition pertaining thereto, except as set forth in the Securities or pursuant to applicable community property laws. Stockholder has duly executed and delivered this Agreement and this Agreement is a legal, valid and binding agreement of Stockholder, enforceable against Stockholder in accordance with its terms, except to the extent enforceability may be limited by the effect of applicable bankruptcy, reorganization, insolvency, moratorium or other Laws affecting the enforcement of creditors’ rights generally and the effect of general principles of equity, regardless of whether such enforceability is considered in a proceeding at Law or in equity. If the Stockholder is married and the Securities constitute community property, this Agreement has been duly authorized, executed and delivered by the Stockholder’s spouse, and this Agreement is a legal, valid and binding agreement of the Stockholder’s spouse, enforceable against the Stockholder’s spouse in accordance with its terms, except to the extent enforceability may be limited by the effect of applicable bankruptcy, reorganization, insolvency, moratorium or other Laws affecting the enforcement of creditors’ rights generally and the effect of general principles of equity, regardless of whether such enforceability is considered in a proceeding at Law or in equity.

2.3 No Violation. Neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated hereby will (a) require the Stockholder to file or register with, or obtain any permit, authorization, consent or approval of, any governmental agency, authority, administrative or regulatory body, court or other tribunal, foreign or domestic, or any other entity other than filings with the SEC pursuant to the Exchange Act, or (b) violate, or cause a breach of or default under, or conflict with any contract, agreement or understanding, any Law binding upon the Stockholder, except for such violations, breaches, defaults or conflicts which are not, individually or in the aggregate, reasonably likely to have an adverse effect on the Stockholder’s ability to satisfy its obligations under this Agreement. As of the date hereof, no proceedings are pending which, if adversely determined, will have an adverse effect on the Stockholder’s ability to vote or dispose of any of the Securities.

2.4 Stockholder Has Adequate Information. Stockholder is a sophisticated seller with respect to the Securities and has adequate information concerning the business and financial condition of the Company to make an informed decision regarding the sale of the Securities and has independently and without reliance upon either Sub or Parent and based on such information as Stockholder has deemed appropriate, made its own analysis and decision to enter into this Agreement. Stockholder acknowledges that neither Sub nor Parent has made and neither makes any representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement. Stockholder acknowledges that the agreements contained herein with respect to the Securities held by Stockholder are irrevocable (prior to the Termination Date), and that Stockholder shall have no recourse to the Securities, Parent or Sub, except with respect to breaches of representations, warranties, covenants and agreements expressly set forth in this Agreement.

2.5 No Setoff. The Stockholder has no liability or obligation related to or in connection with the Securities other than the obligations to Parent and Sub as set forth in this Agreement.

2.6 No Amounts Payable to Stockholder. Except as disclosed in the Merger Agreement or Schedule 2.6 of this Agreement, there are no amounts due or payable by the Company or any Company Subsidiary to the Stockholder or any of its affiliates or associates in connection with the transactions contemplated by the Merger Agreement or this Agreement or otherwise (other than any payments required under the Merger Agreement solely in exchange for equity securities of the Company or payments, if any, to be made pursuant to Plans disclosed in the Company Disclosure Schedule).

3. Representations and Warranties of Parent and Sub. Parent and Sub hereby represent and warrant to Stockholder, as of the date hereof that:

3.1 Authorization. Parent and Sub have all requisite corporate power and authority to execute and deliver this Agreement and to consummate the transactions contemplated hereby. Parent and Sub have duly executed and delivered this Agreement and this Agreement is a legal, valid and binding agreement of each of Parent and Sub, enforceable against each of Parent and Sub in accordance with its terms, except to the extent enforceability may be limited by the effect of applicable bankruptcy, reorganization, insolvency, moratorium or other Laws affecting the enforcement of creditors’ rights generally and the effect of general principles of equity, regardless of whether such enforceability is considered in a proceeding at Law or in equity.

3.2 No Violation. Neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated hereby will violate, or cause a breach of or default under, any contract or agreement, any statute or law, or any judgment, decree, order, regulation or rule of any governmental agency, authority, administrative or regulatory body, court or other tribunal, foreign or domestic, or any other entity or any arbitration award binding upon Parent or Sub, except for such violations, breaches or defaults which are not reasonably likely to have a material adverse effect on either Parent’s or Sub’s ability to satisfy its obligations under this Agreement.

4. Survival of Representations and Warranties. The respective representations and warranties of Stockholder, Parent and Sub contained herein shall not be deemed waived or otherwise affected by any investigation made by the other party hereto.

5. Specific Performance. Stockholder acknowledges that Sub and Parent will be irreparably harmed and that there will be no adequate remedy at law for a violation of any of the covenants or agreements of Stockholder which are contained in this Agreement. It is accordingly agreed that, in addition to any other remedies which may be available to Sub and Parent upon the breach by Stockholder of such covenants and agreements, Sub and Parent shall have the right to obtain injunctive relief to restrain any breach or threatened breach of such covenants or agreements or otherwise to obtain specific performance of any of such covenants or agreements.

6.1 Term. [Chief Executive Officer only: Except for the obligations set forth in Section 1.9 hereof, which obligations survive for the period set forth in Section 1.9,] this

Agreement and all obligations hereunder shall terminate upon the earlier of (a) the Effective Time, (b) the Outside Date (as defined in the Merger Agreement), (c) the date of any modification, waiver or amendment to the Merger Agreement in a manner that reduces the amount and form of consideration payable thereunder to the Stockholder, and (d) the termination of the Merger Agreement pursuant to Section 8.1 thereof (the earliest of (a), (b), (c) and (d), the “Termination Date”). Upon termination of this Agreement, no party shall have any further obligations or liabilities under this Agreement; provided, however, that (i) nothing set forth in this Section 6.1 shall relieve any party from liability for any willful breach of this Agreement prior to termination hereof, and (ii) the provisions of this Article 6 shall survive any termination of this Agreement.

6.2 Capacity as a Stockholder; Fiduciary Duties. Notwithstanding anything in this Agreement to the contrary: (a) the Stockholder makes no agreement or understanding herein in any capacity other than in the Stockholder’s capacity as a record holder and beneficial owner of Securities, and not in such Stockholder’s capacity as a director, officer or employee of the Company or any of Company Subsidiaries or in such Stockholder’s capacity as a trustee or fiduciary of any employee benefit plan or trust, and (b) nothing herein will be construed to limit or affect any action or inaction by the Stockholder or any Representative of the Stockholder, as applicable, serving on the Company Board of Directors or on the board of directors of any Company Subsidiary or as an officer or fiduciary of the Company, any Company Subsidiary or any employee benefit plan or trust, acting in such person’s capacity as a director, officer, trustee and/or fiduciary.

6.3 Expenses. Each of the parties hereto shall pay its own expenses incurred in connection with this Agreement. Each of the parties hereto warrants and covenants to the others that it will bear all claims for brokerage fees attributable to action taken by it.

6.4 Binding Effect. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective representatives and permitted successors and assigns.

6.5 Entire Agreement. This Agreement contains the entire understanding of the parties and supersedes all prior agreements and understandings between the parties with respect to its subject matter. This Agreement may be amended only by a written instrument duly executed by the parties hereto.

6.6 Headings. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

6.7 Assignment. Without limitation to Section 1.1, this Agreement shall be binding upon and inure to the benefit of the parties named herein and their respective successors and permitted assigns. No party may assign either this Agreement or any of its rights, interests, or obligations hereunder without the prior written approval of the other parties; provided, however, that each of Parent and Sub may freely assign its rights to another direct or indirect wholly owned subsidiary of Parent or Sub without such prior written approval but no such assignment shall relieve Parent or Sub of any of its obligations hereunder; and provided, further, that in connection with any assignment under this Section 6.7 that would increase the amount, if

any, required to be deducted or withheld from amounts payable or otherwise deliverable pursuant to this Agreement to Stockholder under the Tax Law of a jurisdiction outside the United States, such assignment shall be null and void unless Parent, Sub and the applicable assignee specifically agree that the last sentence of Section 1.6(d) shall also apply with respect to such increase such that Stockholder shall receive the same amount that would otherwise have been received if no such assignment been made. Any purported assignment requiring consent without such consent shall be void.

6.8 Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be an original, but each of which together shall constitute one and the same Agreement.

6.9 Notices. Any notice or other communication required or permitted hereunder shall be in writing and shall be deemed given when delivered in person, by overnight courier, by facsimile transmission (with receipt confirmed by telephone or by automatic transmission report) or by electronic mail, or two business days after being sent by registered or certified mail (postage prepaid, return receipt requested), as follows:

Any party may by notice given in accordance with this Section 6.9 to the other parties to designate updated information for notices hereunder.

6.10 Governing Law. This Agreement shall be governed by and construed and enforced in accordance with the Laws of the State of Delaware, without regard to its principles of conflicts of Laws.

6.11 Enforceability. The invalidity or unenforceability of any provision or provisions of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, which shall remain in full force and effect. Upon a determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto will, subject to Section 1.9(d), negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible and, absent agreement among the parties, a court is authorized to so modify this Agreement. Without limiting the foregoing, the covenants contained herein shall be construed as separate covenants, covering their respective subject matters, with respect to each of the separate cities, counties and states of the United States, and each other country, and political subdivision thereof, in which any of the Company or its successors now transacts any business.

6.12 Further Assurances. From time to time, at Parent’s request and without further consideration, Stockholder shall execute and deliver to Parent such documents and take such action as Parent may reasonably request in order to consummate more effectively the transactions contemplated hereby and to vest in Parent good, valid and marketable title to the Securities, including, but not limited to, using its best efforts to cause the appropriate transfer agent or registrar to transfer of record the Securities.

6.13 Remedies Not Exclusive. All rights, powers and remedies provided under this Agreement or otherwise available in respect hereof at law or in equity will be cumulative and not alternative, and the exercise of any thereof by either party will not preclude the simultaneous or later exercise of any other such right, power or remedy by such party.

6.14 Waiver of Jury Trial. EACH PARTY HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

6.15 No Agreement Until Executed. Irrespective of negotiations among the parties or the exchanging of drafts of this Agreement, this Agreement shall not constitute or be deemed to evidence a contract, agreement, arrangement or understanding between the parties hereto unless and until (a) the Company Board of Directors has approved, for purposes of any applicable anti-takeover laws and regulations, and any applicable provision of the Company’s certificate of incorporation, the possible acquisition of the Shares by Parent and Sub pursuant to the Merger Agreement, (b) the Merger Agreement is executed by all parties thereto, and (c) this Agreement is executed by all parties hereto.

IN WITNESS WHEREOF, Parent, Sub and Stockholder have caused this Agreement to be duly executed as of the day and year first above written.
