ARTICLE I

THE OFFER

Section 1.1                                    The Offer.

(a)                       Subject to the conditions of this Agreement, as promptly as practicable (but in no event later than five (5) business days) after the date of this Agreement, Merger Sub shall, and Parent shall cause Merger Sub to, 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 to purchase all of the outstanding shares of Company Common Stock; provided, that the Company agrees that no shares of Company Common Stock owned by the Company will be tendered pursuant to the Offer. The obligations of Merger Sub to, and of Parent to cause Merger Sub to, accept for payment, and pay for, any shares of Company Common Stock tendered pursuant to the Offer are subject only to the conditions set forth in Exhibit A (as they may be amended in accordance with this Agreement, the “Offer Conditions”).

(i)             The initial expiration date of the Offer shall be midnight, New York City time, on the 20th business day following the commencement of the Offer (determined pursuant to Rule 14d-1(g)(3) under the Exchange Act). Merger Sub expressly reserves the right, at any time, to, in its sole discretion, waive, in whole or in part, any Offer Condition or modify the terms of the Offer; provided, however, that, without the prior written consent of the

2

Company, Merger Sub shall not (A) reduce the number of shares of Company Common Stock subject to the Offer, (B) reduce the Offer Price or change the form of consideration payable in the Offer, (C) change, modify or waive the Minimum Tender Condition (as defined in Exhibit A), (D) add to the Offer Conditions, or (E) otherwise amend the Offer in any manner adverse to the holders of Company Common Stock.

(ii)          Parent and Merger Sub agree that if on any scheduled expiration date of the Offer, any of the conditions to the offer (including the Minimum Tender Condition and the other conditions and requirements set forth herein and in Exhibit A) is not satisfied or, in Merger Sub’s sole discretion, waived, then Merger Sub shall, and Parent shall cause Merger Sub to, extend the Offer for successive periods of time to be determined at the sole discretion of the Merger Sub; provided, however, that in no event shall Merger Sub be required to extend the Offer (1) beyond the Outside Date or (2) at any time that Parent or Merger Sub is permitted to terminate this Agreement pursuant to ARTICLE VIII.

(iii)       On the terms and subject to the conditions of this Agreement, Merger Sub shall, and Parent shall cause Merger Sub to, accept and pay for (subject to any withholding of tax pursuant to Section 1.1(d)) all shares of Company Common Stock validly tendered and not validly withdrawn pursuant to the Offer as soon as practicable after Merger Sub is legally permitted to do so under applicable Law. Acceptance for payment of shares of Company Common Stock pursuant to and subject to the conditions of the Offer upon the expiration of the Offer is referred to in this Agreement as the “Offer Closing”, and the date on which the Offer Closing occurs is referred to in this Agreement as the “Offer Closing Date”.  Merger Sub expressly reserves the right to, in its sole discretion, following the Offer Closing, extend the Offer for a “subsequent offering period” in accordance with Rule 14d-11 under the Exchange Act, and the Offer Documents (as defined below) may, in Merger Sub’s sole discretion, provide for such a reservation of right. Nothing contained in this Section 1.1(a) shall affect any termination rights in ARTICLE VIII.

(b)                       On the date of commencement of the Offer, Parent and Merger Sub shall file with the SEC a Tender Offer Statement on Schedule TO with respect to the Offer (together with all amendments and supplements thereto and including exhibits thereto, the “Schedule TO”), which shall contain an offer to purchase and a related letter of transmittal and summary advertisement and other appropriate ancillary offer documents (such Schedule TO and the documents included therein pursuant to which the Offer will be made, together with any supplements or amendments thereto, the “Offer Documents”), and cause the Offer Documents to be disseminated to the stockholders of the Company as and to the extent required by federal securities laws. Each of Parent, Merger Sub and the Company shall promptly correct any information supplied by it for inclusion or incorporation by reference in the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect, and each of Parent and Merger Sub shall take all steps necessary to amend or supplement the Offer Documents and to cause the Offer Documents as so amended or

3

supplemented to be filed with the SEC and disseminated to the stockholders of the Company, in each case as soon as reasonably practicable and as and to the extent required by applicable federal securities laws. Parent and Merger Sub shall promptly notify the Company upon the receipt of any comments from the SEC, or any request from the SEC for amendments or supplements, to the Offer Documents, and shall promptly provide the Company with copies of all correspondence and summaries of all material oral communications between them and their representatives, on the one hand, and the SEC, on the other hand. Prior to the filing of the Offer Documents (including any amendment or supplement thereto) with the SEC or dissemination thereof to the stockholders of the Company, or responding to any comments of the SEC with respect to the Offer Documents, Parent and Merger Sub shall provide the Company and its counsel a reasonable opportunity to review and comment on such Offer Documents or response, and Parent and Merger Sub shall give reasonable consideration to any such comments. In the event that Parent or Merger Sub receives any comments from the SEC or its staff with respect to the Offer Documents, each shall use its reasonable best efforts to (i) respond promptly to such comments and (ii) take all other actions necessary to resolve the issues raised therein.

(c)                        Parent shall provide or cause to be provided to Merger Sub on a timely basis the consideration necessary to pay for any shares of Company Common Stock that Merger Sub becomes obligated to accept for payment, and pay for, pursuant to the Offer and shall cause Merger Sub to fulfill all of Merger Sub’s obligations under this Agreement.

(d)                       Parent, Merger Sub or the paying agent for the Offer (the “Paying Agent”) shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to the Offer to any holder of shares of Company Common Stock such amounts as Parent, Merger Sub or the Paying Agent is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended, and applicable Treasury Regulations issued pursuant thereto (the “Code”), or any provision of state or local Tax law. To the extent that amounts are so withheld and paid over by Parent, Merger Sub or the Paying Agent to the appropriate taxing authority, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock in respect of which such deduction and withholding was made by Parent, Merger Sub or the Paying Agent.

Prior to the filing of the Schedule 14D-9 (including any amendment or supplement thereto) with the SEC or mailing thereof to the stockholders of the Company, or responding to any comments of the SEC with respect to the Schedule 14D-9, the Company shall provide Parent and its counsel a reasonable opportunity to review and comment on such Schedule 14D-9 or response, and the Company shall give reasonable and good faith consideration to any comments made by Parent, Merger Sub and their counsel. The Company hereby consents to the inclusion in the Offer Documents of the recommendation of the Company Board contained in the Schedule 14D-9.  In the event that the Company receives any comments from the SEC or its staff with respect to the Schedule 14D-9, it shall use its reasonable best efforts to (i) respond promptly to such comments and (ii) take all other actions necessary to resolve the issues raised therein.

(c)                        In connection with the Offer and the Merger, the Company shall cause its transfer agent to furnish Parent and Merger Sub promptly with mailing labels containing the names and addresses of the record holders of Company Common Stock as of the latest practicable date and of those persons becoming record holders subsequent to such date, together with copies of all lists of stockholders, security position listings and computer files and all other information in the Company’s possession or control regarding the beneficial owners of Company Common Stock, and shall furnish to Parent and Merger Sub such information and assistance (including periodically updated lists of stockholders, security position listings and computer files) as Parent may reasonably request in communicating the Offer to holders of Company Common Stock. Parent and Merger Sub shall take such actions as may be reasonably

5

required to protect the unauthorized disclosure or use of information received by it pursuant to this Section 1.2.

Section 1.3                                    Directors.

(a)                       Effective upon the Offer Closing and from time to time thereafter, Parent shall be entitled to designate the number of directors, rounded up to the next whole number, on the Company Board that equals the product of (i) the total number of directors on the Company Board (giving effect to the election of any additional directors pursuant to this Section 1.3) and (ii) the percentage that the number of shares of Company Common Stock beneficially owned by Parent and/or Merger Sub (including shares accepted for payment) bears to the total number of shares outstanding, and the Company shall cause Parent’s designees to be elected or appointed to the Company Board, including by increasing the number of directors and seeking and accepting resignations of incumbent directors. At such time, the Company shall also cause individuals designated by Parent to constitute the number of members, rounded up to the next whole number, on each committee of the Company Board that represents the same percentage as such individuals represent on the Company Board.

(b)                       The Company’s obligations to appoint Parent’s designees to the Company Board shall be subject to Section 14(f) of the 1934 Act and Rule 14f-1 promulgated thereunder. The Company shall promptly take all actions necessary to effect the appointment of Parent’s designees, including mailing to its stockholders information with respect to the Company and its officers and directors, as Section 14(f) and Rule 14f-1 require in order to fulfill its obligations under this Section 1.3(b), which, unless Parent otherwise elects, shall be mailed together with the Schedule 14D-9. Parent shall supply to the Company in writing and be solely responsible for any information with respect to itself and its nominees, officers, directors and affiliates required by Section 14(f) and Rule 14f-1 and the Company’s obligations under Section 1.3(a) hereof shall be subject to the receipt of such information.

(c)                        Following the election or appointment of Parent’s designees pursuant to Section 1.3(a) and until the Effective Time (as defined in Section 2.2(b) hereof), the approval of a majority of the directors of the Company then in office who were not designated by Parent shall be required to authorize (and such authorization shall constitute the authorization of the Company Board and no other action on the part of the Company, including any action by any other director of the Company, shall be required to authorize) any termination of this Agreement by the Company, any amendment of this Agreement requiring action by the Company Board, any extension of time for performance of any obligation or action hereunder by Parent or Merger Sub, any waiver of compliance with any of the agreements or conditions contained herein for the benefit of the Company or any other action (or inaction) under or in connection with this Agreement if such action (or inaction) would reasonably be expected to adversely affect the Company’s stockholders (other than Parent or Merger Sub).

(a)                       Conversion of Company Common Stock.  Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (including all vested and unvested shares of restricted stock issued in connection with restricted stock awards granted to the executive officers of the Company (the transfer restrictions on which shares shall terminate immediately prior to the Effective Time) but not including shares to be cancelled pursuant to Section 3.1(c) hereof and Dissenting Shares) shall be converted into the right to receive cash and the Contingent Cash Consideration Payments equal in form and amount to the Offer Price paid in the Offer (the “Merger Consideration”).  As of the Effective Time, all such shares of Company Common Stock shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of any Company Common Stock shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration, to be issued or paid in consideration therefor in accordance with Section 3.2, without interest.

(b)                       Conversion of Merger Sub Common Stock.  Each share of common stock, par value $0.01 per share, of Merger Sub (the “Merger Sub Common Stock”) that is issued and outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid and nonassessable share of common stock, $0.001 par value per share, of the Surviving Corporation, and the shares of the Surviving Corporation into which the shares of Merger Sub Common Stock are so converted shall be the only shares of the Surviving Corporation that are issued and outstanding immediately after the Effective Time.  Following the Effective Time, each certificate evidencing ownership of shares of Merger Sub Common Stock shall evidence ownership of such shares of the Surviving Corporation.

8

(c)                        Cancellation of Certain Shares.  Each share, if any, of Company Common Stock that is held by the Company as treasury shares and each share of Company Common Stock which is owned by the Company or Parent or by any direct or indirect wholly-owned subsidiary of the Company or Parent shall be cancelled without any conversion, and no consideration shall be delivered in respect thereof.

(d)                       Company Options.  Effective not later than the Closing, the Company shall take all actions required to provide that, effective as of the Closing, the Company Stock Plan (as defined in Section 4.2(a) hereof) and all Company Options (as defined in Section 4.2(a) hereof) outstanding immediately before the Closing shall be cancelled and of no further force or effect, and in consideration for such cancellation of Company Options outstanding under the Company Stock Plan immediately before the Closing, the holders thereof (whether or not such Company Options shall otherwise be exercisable at the Effective Time) shall automatically (and without any further action being required on the part of the holders thereof) receive, at the earliest Valuation Point, if any, at which the then applicable Per Share Paid Value exceeds the per-share exercise price under such Company Option:

(i)             an amount in cash equal to (A) the number of shares of Company Common Stock subject to each such Company Option (whether vested or unvested) held by such holder multiplied by the excess, of (1) the then applicable Per Share Paid Value over (2) the per-share exercise price under such Company Option (with such payments to be subject to any applicable Tax withholding in accordance with Section 3.1(h)); and

(ii)          the right to receive, in respect of each share of Company Common Stock subject to each such Company Option (whether vested or unvested) held by such holder, each Contingent Cash Consideration Payment that, as of such Valuation Point, has not yet become payable pursuant to the terms of the Contingent Cash Consideration Agreement.

(e)                        Other Equity Awards. Effective not later than the Closing, the Company shall take all actions required to provide that (i) each award (“Other Equity Award”) outstanding immediately before the Effective Time under the Company Stock Plans other than the Company Options (including any restricted stock units) shall be cancelled and of no further force or effect as of the Effective Time and (ii) in exchange for the cancellation of each such Other Equity Award, to the extent vested as of immediately before the Effective Time, in accordance with the terms of such Other Equity Award (including any vesting that occurs under the terms of the applicable Other Equity Award as a result of the consummation of this Agreement), the holder of such Other Equity Awards shall receive the per share Merger Consideration for each share of Company Common Stock underlying such Other Equity Award (with such payment to be subject to any applicable Tax withholding in accordance with Section 3.1(h)).  Prior to the Effective Time, the Company shall take all actions necessary such that no Person has any rights to acquire Company Common Stock or common stock of the Parent or any of its subsidiaries (including the Surviving Corporation) pursuant to any Company Benefit Plan or Company Benefit Agreement following the Effective Time.  Additionally, prior to the Effective Time, the Company Board shall take any actions required to accelerate the vesting of, or cause the lapsing of any restrictions with respect to, any Other Equity Award.

9

(f)                         2010 Employee Stock Purchase Plan.  Effective not later than the Closing, the Company shall take all actions required to provide that, as of the Closing Date, the 2010 Employee Stock Purchase Plan of the Company (the “2010 ESPP”) shall be terminated.  The Company shall not commence any new purchase periods under the 2010 ESPP after the date hereof.

(g)                        Warrants.  Each outstanding unexercised warrant to purchase or otherwise acquire shares of Company Common Stock immediately prior to the Offer Closing (each, a “Company Warrant”) shall as a consequence of the Offer Closing, only entitle the holder thereof to receive, upon exercise in accordance with its terms, at the earliest Valuation Point, if any, at which the then applicable Per Share Paid Value exceeds the per-share exercise price under such Company Warrant, the Offer Price, in accordance with the terms of such Company Warrant.  As a consequence of the Closing, each such Company Warrant shall automatically be assumed by the Surviving Corporation.  Promptly following the date of this Agreement, the Company shall deliver written notice to each holder of a Company Warrant, in accordance with the terms of the applicable Company Warrant, informing such holders of the effect of the Offer on the Company Warrants.

(h)                       Withholding. Parent, the Surviving Corporation or the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Company Common Stock, Company Options or Other Equity Awards such amounts as Parent, the Surviving Corporation or the Exchange Agent is or may be reasonably required to deduct and withhold with respect to the making of such payment under applicable Law. To the extent that amounts are so withheld and paid over to the appropriate taxing authority by Parent, the Surviving Corporation or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Company Common Stock, Company Options or Other Equity Awards in respect of which such deduction and withholding was made by Parent, the Surviving Corporation or the Paying Agent.

Section 3.2                                    Exchange of Shares and Certificates.

(a)                       Exchange Agent.  At or prior to the Effective Time, Parent shall engage a nationally-recognized financial institution reasonably satisfactory to the Company to act as exchange agent in connection with the Merger (the “Exchange Agent”).  At the Effective Time, Parent shall deposit with the Exchange Agent, in trust for the benefit of the holders of shares of Company Common Stock immediately prior to the Effective Time, the cash portion of the Merger Consideration to be paid in respect of the Company Common Stock.  All cash deposited with the Exchange Agent shall hereinafter be referred to as the “Exchange Fund.”  If for any reason (including losses) the Exchange Funds shall be insufficient to fully satisfy all of the payment obligations to be made by the Exchange Agent hereunder, Parent will, or will cause Merger Sub (or after the Effective Time, the Surviving Corporation) to, promptly deposit cash with the Exchange Agent in an amount which is equal to the deficiency required to fully satisfy such cash payment obligations.

(b)                       Exchange Procedures.  Promptly after the Effective Time, Parent shall cause the Exchange Agent to mail to each holder of record of (i) a certificate or certificates

10

which immediately prior to the Effective Time represented outstanding shares of Company Common Stock (the “Certificates”) or (ii) uncertificated shares of Company Common Stock (the “Uncertificated Shares”), in each case, which at the Effective Time were converted into the right to receive the Merger Consideration pursuant to Section 3.1 hereof, (A) a letter of transmittal (which, in the case of Certificates, shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Parent may reasonably specify) and (B) instructions for use in effecting the surrender of the Certificates or Uncertificated Shares in exchange for the Merger Consideration.  Upon (1) surrender of Certificates for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto or (2) or receipt of an “agent’s message” by the Exchange Agent (or such other evidence, if any, of transfer as the Exchange Agent may reasonably request) in the case of a book-entry transfer of Uncertificated Shares, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificates or Uncertificated Shares shall be entitled to receive in exchange the portion of the Merger Consideration to which such holder is entitled pursuant to Section 3.1, and any Certificates so surrendered shall forthwith be cancelled.  If any portion of the Merger Consideration is to be paid to a Person other than the Person in whose name the surrendered Certificate or the transferred Uncertificated Share is registered, it shall be a condition to such payment that (I) either such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer or such Uncertificated Share shall be properly transferred and (II) the Person requesting such payment shall pay to the Exchange Agent any transfer or other Taxes required as a result of such payment to a Person other than the registered holder of such Certificate or Uncertificated Share or establish to the satisfaction of Parent that such Tax has been paid or is not payable.  Until surrendered as contemplated by this Section 3.2(b), each Certificate or Uncertificated Share shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration upon such surrender.

(c)                        No Further Ownership Rights in Company Common Stock.  All Merger Consideration issued and paid upon the surrender for exchange of Certificates or Uncertificated Shares in accordance with the terms of this ARTICLE III shall be deemed to have been issued and paid in full satisfaction of all rights pertaining to the shares of Company Common Stock previously represented by such Certificates or Uncertificated Shares.  At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock which were outstanding immediately prior to the Effective Time.  If, after the Effective Time, Certificates or Uncertificated Shares are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this ARTICLE III.

(d)                       Termination of Exchange Fund.  Any portion of the Exchange Fund which remains undistributed to the holders of Company Common Stock 12 months after the Effective Time shall be delivered to Parent, upon demand, and any holders of Company Common Stock who have not theretofore complied with this ARTICLE III shall thereafter look only to Parent for payment of their claim for the Merger Consideration, and Parent and the

44

review pursuant to this Section 6.2 shall affect or be deemed to modify any representation or warranty contained herein, the covenants or agreements of the parties hereto or the conditions to the obligations of the parties hereto under this Agreement.  All information provided pursuant to this Section 6.2 shall be subject to the terms of the Confidentiality Agreement.

Section 6.3                                    Notification of Certain Matters; Regulatory Communications.

(a)                       Parent shall give prompt notice to the Company and the Company shall give prompt notice to Parent, as the case may be, of the occurrence, or failure to occur, of any event, which occurrence or failure to occur is reasonably likely to cause (a)(i) any representation or warranty of such party contained in this Agreement that is qualified as to “materiality”, “Company Material Adverse Effect” or “Parent Material Adverse Effect” to be untrue or inaccurate in any respect or (ii) any other representation or warranty of such party contained in this Agreement to be untrue or inaccurate in any material respect, in each case at any time from and after the date of this Agreement until the Offer Closing or (b) any material failure of Parent and Merger Sub or the Company, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it under this Agreement.  In addition, Parent shall give prompt notice to the Company and the Company shall give prompt notice to Parent, as the case may be, of any change or event having, or which is reasonably likely to have, a Company Material Adverse Effect or Parent Material Adverse Effect, as the case may be, or which would be reasonably likely to result in the failure of any of the conditions set forth in Annex A to be satisfied.  Notwithstanding the above, the delivery of any notice pursuant to this Section 6.3 will not limit or otherwise affect the representations, warranties, covenants or agreements of the parties, the remedies available hereunder to the party receiving such notice or the conditions to such party’s obligation to consummate the Offer or the Merger.

Section 6.4                                    Antitrust Filings; Reasonable Best Efforts.

(a)                       In the event that Parent determines, in good faith, that any filing would be necessary under the HSR Act or any Competition Laws, as the case may be, Parent shall promptly notify the Company of such determination and each party shall make or cause to be made, in cooperation with the other parties and to the extent applicable and as promptly as practicable (but in no event later than five business days) after the date of such notification, (i) an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the transactions contemplated hereby and (ii) all other necessary filings, forms, declarations, notifications, registrations and notices with other Governmental Entities under Competition Laws relating to the transactions contemplated hereby.  “Competition Laws” mean the HSR Act,

(b)                       Subject to Section 6.4(c), each of the parties to this Agreement agrees to use its 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 to this Agreement 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 by this Agreement, including (i) the obtaining of all other necessary actions or nonactions, waivers, consents, licenses, permits, authorizations, orders and approvals from Governmental Entities and the making of all other necessary registrations and filings (including filings with Governmental Entities, if any), (ii) the obtaining of all consents, approvals or waivers from third parties related to or required in connection with the Offer or the Merger that are necessary to consummate the Offer, the Merger and the transactions contemplated by this Agreement, (iii) the preparation of any documents that may be required to be filed with the SEC, (iv) the execution and delivery of any additional instruments reasonably necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, this Agreement, and (v) the providing of all such information concerning such party, its subsidiaries, its Affiliates and its subsidiaries’ and

46

Affiliates’ officers, directors, employees and partners as may be reasonably requested in connection with any of the matters set forth in Section 6.4(a) or this Section 6.4(b).  Each of Parent and the Company agrees that it will use its reasonable best efforts to obtain each of the consents or provide each of the notices, as applicable, prior to the Offer Closing, that are listed in Section 6.4(b) of the Company Disclosure Letter.

(c)                        Notwithstanding anything to the contrary in this Section 6.4, neither Parent nor the Company shall be required in order to resolve any objections asserted under Competition Laws by any Governmental Entity with respect to the transactions contemplated by this Agreement to divest any of its businesses, product lines or assets, or take or agree to take any other action or agree to any limitation or restriction.

Section 6.5                                    No Solicitation; Company Board Recommendation.

(a)                       The Company shall not, nor shall it authorize or permit any of its Representatives to, directly or indirectly, (i) solicit, initiate or encourage, or take any other action designed to, or which is reasonably expected to, facilitate, any Company Takeover Proposal, (ii) enter into any agreement with respect to any Company Takeover Proposal or (iii) enter into, continue or otherwise participate in any discussions or negotiations regarding, or furnish to any Person any information with respect to, or otherwise cooperate with, any proposal that constitutes, or is reasonably expected to lead to, any Company Takeover Proposal.  The Company shall, and shall cause its Representatives to, immediately cease and cause to be terminated all existing discussions or negotiations with any Person conducted heretofore with respect to any proposal that constitutes, or is reasonably expected to lead to, any Company Takeover Proposal and request the prompt return or destruction of all confidential information previously furnished to any such Person. Notwithstanding the foregoing, at any time prior to the Offer Closing, in response to a bona fide written Company Takeover Proposal that the Company Board determines (after consultation with outside counsel and a financial advisor of nationally recognized reputation) constitutes, or is reasonably expected to lead to, a Superior Proposal, and which Company Takeover Proposal was not solicited after the date hereof, was made after the date hereof and did not otherwise result from a breach of this Section 6.5(a), the Company may, if a majority of the Company Board determines (after consultation with outside counsel) that failure to take such actions would be inconsistent with its fiduciary duties to the stockholders of the Company under applicable Law, and subject to compliance with this Section 6.5(a) and Section 6.5(c) and after giving Parent written notice of such determination, (x) furnish information with respect to the Company to the Person making such Company Takeover Proposal (and its Representatives) pursuant to a customary confidentiality agreement (which agreement shall include a customary “standstill” or similar covenant) not less restrictive of such Person than the Confidentiality Agreement and containing provisions allowing necessary disclosures to Parent pursuant to Section 6.5(c) hereof; provided that (1) all such information has previously been provided to Parent or is provided to Parent prior to the time it is provided to such Person and (2) such customary confidentiality agreement expressly provides the right for the Company to comply with the terms of this Agreement, including Section 6.5(b) and Section 6.5(c), and (y) participate in discussions or negotiations with the Person making such Company Takeover Proposal (and its Representatives) regarding such Company Takeover Proposal.  Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in this Section 6.5(a) by any Representative or Affiliate of the Company shall be deemed to be a breach

47

of this Section 6.5(a) by the Company.  Notwithstanding the foregoing, the Company’s release or waiver of any “standstill” agreement to which it is a party shall not violate this Section 6.5; provided that the Company shall advise Parent orally and in writing no later than 24 hours prior to any such release or waiver that the Company shall enter into such release or waiver.

The term “Company Takeover Proposal” means any inquiry, proposal or offer from any Person relating to, or that is reasonably expected to lead to, any direct or indirect acquisition or purchase, in one transaction or a series of transactions, of any Product or of assets or businesses that constitute 15% or more of the revenues, net income, EBITDA (earnings before interest expense, taxes, depreciation and amortization) or the assets of the Company, taken as a whole, or 15% or more of any class of equity securities of the Company, any tender offer or exchange offer that if consummated would result in any Person beneficially owning 15% or more of any class of equity securities of the Company, or any merger, consolidation, business combination, recapitalization, liquidation, dissolution, joint venture, binding share exchange or similar transaction involving the Company pursuant to which any Person or the stockholders of any Person would own 15% or more of any class of equity securities of the Company or of any resulting parent company of the Company, other than the transactions contemplated by this Agreement.

The term “Superior Proposal” means a bona fide Company Takeover Proposal (provided, that for purposes of this definition references to 15% in the definition of “Company Takeover Proposal” shall be deemed to be references to 50%) which the Company Board determines in good faith (after consultation with outside counsel and a financial advisor of nationally recognized reputation) to be (i) more favorable to the stockholders of the Company from a financial point of view than the Offer and the Merger, taking into account all relevant factors (including all the terms and conditions of such proposal and the Offer and this Agreement (including any changes to the terms of the Offer and this Agreement proposed by Parent in response to such offer or otherwise)) and (ii) reasonably capable of being completed, taking into account all financial, legal, regulatory and other aspects of such proposal.

(b)                       Neither the Company Board nor any committee thereof shall, (i) (A) withdraw (or qualify or modify in a manner adverse to Parent or Merger Sub), or publicly propose to withdraw (or qualify or modify in a manner adverse to Parent or Merger Sub), the adoption, approval, recommendation or declaration of advisability by the Company Board or any such committee thereof of this Agreement, the Offer, the Merger or the other transactions contemplated by this Agreement or (B) recommend, adopt, approve or declare advisable, or propose publicly to recommend, adopt, approve or declare advisable, any Company Takeover Proposal (any action described in this clause (i) being referred to as a “Company Adverse Recommendation Change”) or (ii) adopt, approve, recommend or declare advisable, or propose to adopt, approve, recommend or declare advisable, or allow the Company to execute or enter into, any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement or other similar agreement constituting or related to, or that is intended to or is reasonably expected to lead to, any Company Takeover Proposal (other than a confidentiality agreement referred to in Section 6.5(a) pursuant to and in accordance with the limitations set forth therein).  Notwithstanding the foregoing, at any time prior to the Offer Closing Date, the Company Board may make a Company Adverse Recommendation Change if a majority of the

48

Company Board determines (after consultation with outside counsel) that failure to take such actions would be inconsistent with its fiduciary duties to the stockholders of the Company under applicable Law; provided, however, that no such Company Adverse Recommendation Change may be made until after the second business day following Parent’s receipt of written notice (a “Company Notice of Adverse Recommendation”) from the Company advising Parent that the Company Board intends to take such action and specifying the reasons therefor, including the terms and conditions of any Superior Proposal that is the basis of the proposed action by the Company Board (it being understood and agreed that (x) any amendment to any material term of such Superior Proposal or (y) with respect to any previous Company Adverse Recommendation Change, any material change in the principal stated rationale by the Company Board for such previous Company Adverse Recommendation Change, shall, in the case of either (x) or (y), require a new Company Notice of Adverse Recommendation promptly (and in any case within 24 hours), at which point a new two business day-period shall commence).  In determining whether to make a Company Adverse Recommendation Change, the Company Board shall take into account any changes to the terms of this Agreement proposed by Parent in response to a Company Notice of Adverse Recommendation or otherwise.

(c)                        In addition to the obligations of the Company set forth in Section 6.5(a) and Section 6.5(b), (i) the Company shall promptly advise Parent orally and in writing (and in any case within 24 hours) of any Company Takeover Proposal or any inquiry that is reasonably expected to lead to any Company Takeover Proposal, the material terms and conditions of any such Company Takeover Proposal or inquiry (including any changes thereto) and the identity of the Person making any such Company Takeover Proposal or inquiry and (ii) the Company shall (A) keep Parent fully and promptly informed of the status and material details (including any change to any material term thereof) of any such Company Takeover Proposal or inquiry and (B) provide to Parent promptly after receipt or delivery thereof copies of all correspondence and other written material sent or provided to the Company from any Person that describes any of the terms or conditions of any Company Takeover Proposal or inquiry.  In addition, during the period from the date of this Agreement through the Offer Closing, the Company shall not terminate, amend, modify or waive any provision of any confidentiality agreement to which it is a party.  During such period, the Company shall enforce, to the fullest extent permitted under applicable law, the provisions of any such agreement, including by obtaining injunctions to prevent any breaches of such agreements and to enforce specifically the terms and provisions thereof in any court of the United States of America or of any state having jurisdiction.

(d)                       Nothing contained in this Agreement shall prohibit the Company from taking and disclosing to its stockholders a position contemplated by Rule 14(e)-2(a) or Rule 14(d)-9 promulgated under the Exchange Act or from making any disclosure to the Company’s stockholders (including any amendments to its Schedule 14D-9 relating to a Company Adverse Recommendation Change ) if, in the good faith judgment of the Company Board, after consultation with outside counsel, failure to so disclose would be inconsistent with applicable Law; provided, however, that all actions taken or agreed to be taken by the Company or the Company Board or any committee thereof shall comply with the provisions of Section 6.5(a).

(e)                        Notwithstanding anything in this Section 6.5 to the contrary, the Company shall not, and shall not permit its Subsidiaries to, reimburse or agree to reimburse the

49

expenses of any Third Party (other than the Company’s Representatives) in connection with a Company Takeover Proposal or any inquiry, discussion, offer or request that could reasonably be expected to lead to a Company Takeover Proposal.

Section 6.6                                    Stockholder Litigation.  The Company shall give Parent the opportunity to participate (at Parent’s expense) in the defense or settlement of any stockholder Litigation against the Company and its directors relating to the Offer, the Merger or the other transactions contemplated by this Agreement; provided, however, that no such settlement shall be agreed to without Parent’s prior written consent, which consent shall not be unreasonably conditioned, withheld or delayed, except that Parent shall not be obligated to consent to any settlement which does not include full release of Parent and its Affiliates or which imposes an injunction or other equitable relief upon Parent or any of its Affiliates (including, after the Effective Time, the Surviving Corporation).

Section 6.7                                    Indemnification; Director and Officer Insurance.

(a)                       For not less than six years from and after the Effective Time, Parent agrees to, and to cause the Surviving Corporation to, (i) indemnify and hold harmless all past and present directors, officers and employees of the Company (collectively, the “Indemnified Parties”) to the same extent such Persons are indemnified as of the date of this Agreement by the Company pursuant to the Company Certificate of Incorporation and Company Bylaws and indemnification agreements, if any, in existence on the date of this Agreement with any Indemnified Parties for acts or omissions occurring at or prior to the Effective Time; provided, however, that Parent agrees to, and to cause the Surviving Corporation to, indemnify and hold harmless such Persons to the fullest extent permitted by law for acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby; (ii) advance or pay any expenses of any Indemnified Party with respect to any such matter pursuant to the Company Certificate of Incorporation, Company Bylaws and indemnification agreements; and (iii) cooperate in the defense of any such matter.

(b)                       Parent shall cause the Surviving Corporation to provide, for an aggregate period of not less than six years from the Effective Time, the Company’s current directors and officers an insurance and indemnification policy that provides coverage for events occurring prior to the Effective Time (the “D&O Insurance”) that is no less favorable than the Company’s existing policy or, if substantially equivalent insurance coverage is unavailable, the best available coverage; provided, however, that the Surviving Corporation shall not be required to pay an annual premium for the D&O Insurance in excess of 250 percent of the last annual premium paid prior to the date of this Agreement; provided that Parent may substitute therefor a single premium tail coverage with respect to D&O Insurance at a level at least as favorable as in the D&O Insurance.

(c)                        In the event Parent or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of Parent or the Surviving Corporation, as the case may be, shall assume the obligations set forth in this Section 6.7.

50

(d)                       The rights and obligations under this Section 6.7 shall survive consummation of the Merger and shall not be terminated or amended in a manner that is adverse to any Indemnified Party without the written consent of such Indemnified Party.  It is expressly agreed that the Indemnified Parties to whom this Section 6.7 applies shall be third party beneficiaries of this Section 6.7 and shall be entitled to enforce the covenants and agreements contained herein.

Section 6.8                                    Public Announcements.  The initial press release shall be a joint press release and thereafter, during the period between the date of this Agreement and the earlier of the Offer Closing and the termination of this Agreement in accordance with Section 8.1, the Company and Parent each shall obtain the prior consent of the other prior to issuing any press releases or making other public statements and communications with respect to the Merger, the other transactions contemplated by this Agreement or Products, except as may be required by Law or by obligations pursuant to any listing agreement with or rules of Nasdaq.  In addition, the Company and Parent shall develop a joint communications strategy and each party shall ensure that, during the period between the date of this Agreement and the earlier of the Offer Closing and the termination of this Agreement in accordance with Section 8.1, all press releases and other public statements and communications (including any communications that would require a filing under Rules 14d-2 or 14d-9 of the Exchange Act), with analysts, members of the financial community or otherwise, with respect to the Offer, the Merger, the other transactions contemplated by this Agreement or Products shall be consistent in all material respects with such joint communications strategy.

Section 6.9                                    Employees.

(a)                       For a period of one year following the Offer Closing, Parent shall or shall cause the Surviving Corporation to either (i) provide the employees of the Company who are employed immediately prior to the Effective Time (the “Covered Employees”) who remain employed during such period by Parent, the Surviving Corporation or any of their respective Subsidiaries with compensation and benefits (excluding equity based compensation) which, taken as a whole, have a value substantially comparable, in the aggregate, to the compensation and benefits provided to the respective Covered Employee by the Company as of the date hereof or (ii) provide or cause the Surviving Corporation (or, in such case, its successors or assigns) to provide Covered Employees who remain employed during such period by Parent, the Surviving Corporation or their respective Subsidiaries with compensation and benefits that, taken as a whole, have a value substantially comparable, in the aggregate, to the Covered Employees not less than those provided to similarly situated employees of Parent and its Subsidiaries from time to time.  Parent shall have no obligation and the Company shall take no action that would have the effect of requiring Parent or the Surviving Corporation to continue any specific plans or to continue the employment of any specific Person.

(b)                       For purposes of determining eligibility to participate in, and non-forfeitable rights under, but not for purposes of benefit accrual under, any employee benefit plan or arrangement of Parent or the Surviving Corporation or any of their respective Subsidiaries, Covered Employees shall receive service credit for service with the Company (and with any predecessor or acquired entities or any other entities for which the Company granted service credit) as if such service had been completed with Parent; provided, however, that such service

51

need not be recognized to the extent that such recognition would result in any duplication of benefits for the same period of service.

(c)                        To the extent applicable, Parent shall or shall cause the Surviving Corporation and any of their respective Subsidiaries to waive, or use reasonable best efforts to cause its insurance carriers to waive, any pre-existing condition limitation on participation and coverage applicable to any Covered Employee or any of his or her covered dependents under any health or welfare plan of Parent or the Surviving Corporation or any of their respective Subsidiaries (a “New Plan”) in which such Covered Employee or covered dependent shall become eligible to participate after the Effective Time to the extent such Covered Employee or covered dependent was no longer subject to such pre-existing condition limitation under the corresponding Company Benefit Plan in which such Covered Employee or such covered dependent was participating immediately before he or she became eligible to participate in the New Plan.  Parent shall or shall cause the Surviving Corporation or a Subsidiary of either to provide each Covered Employee with credit for any co-payments and deductibles paid prior to the Effective Time and during the calendar year in which the Effective Time occurs under any Company Benefit Plan in satisfying any applicable co-payment and deductible requirements for such calendar year under any New Plan in which such Covered Employee participates after the Effective Time.

(d)                       Nothing in this Section 6.9 shall confer any rights or remedies of any kind or description upon any Covered Employee or any other Person other than the Company and Parent and their respective successors and assigns or be construed as an amendment, waiver or creation of any Company Benefit Plan or Company Benefit Agreement.

(e)                        The Company shall refrain from causing any employees of the Company to suffer an “employment loss” as defined in the Worker Adjustment and Retraining Notification Act of 1988 or any similar state or local law (collectively, the “WARN Act”), in the ninety-one (91) days prior to the Offer Closing, without the prior consent of Parent.

Parent agrees to take all necessary actions, upon the request of a Covered Employee, to facilitate a direct transfer of an eligible rollover distribution (as defined in section 401(a)(31) of the Code), including any portion of such distribution attributable to outstanding promissory notes, from any Company Benefit Plan to the 401(k) plan sponsored by Parent or the Surviving Corporation; provided, that such request is made not more than sixty (60) days following the Offer Closing.

CONDITIONS OF THE OFFER

Notwithstanding any other provisions of the Offer, Merger Sub shall not be required to, and Parent shall not be required to cause Merger Sub to, accept for payment or, subject to any applicable rules and regulations of the SEC, including Rule 14e-1(c) under the Exchange Act, pay for any tendered shares of Company Common Stock unless:

(i)                                     There shall have been validly tendered and not validly withdrawn prior to the expiration date for the Offer (as it may have been extended or re-extended pursuant to the Agreement, the “Expiration Date”) that number of shares of Company Common Stock which, when added to the shares of Company Common Stock already owned by Parent and its Subsidiaries, represents at least a majority of the total number of outstanding shares of Company Common Stock on a “fully diluted basis”, which assumes conversion or exercise of all derivative securities regardless of the conversion or exercise price, the vesting schedule or other terms and conditions thereof, on the Expiration Date (the “Minimum Tender Condition”); provided that, for purposes of determining the Minimum Tender Condition, Parent and the Company acting jointly will be permitted to disregard the dilutive effect of any Company Warrants;

(ii)                                  Any waiting period (and any extension thereof) applicable to the consummation of the Offer under the HSR Act and any other applicable foreign antitrust, competition or similar Law shall have expired or been terminated;

(iii)                               No applicable Law and no permanent injunction or other judgment, order or decree entered, enacted, promulgated, enforced or issued by any court or other Governmental Entity of competent jurisdiction in the United States or any material foreign jurisdiction shall be and remain in effect which has the effect of prohibiting the consummation of the Offer, the Merger or the other transactions contemplated by the Agreement;

(iv)                              There shall not be existing any temporary restraining order, preliminary injunction, pending or threatened any suit, action or proceeding by any Governmental Entity which challenges or seeks to enjoin the Offer Closing, the Merger or the other transactions contemplated by the Agreement;

(v)                                 (A) The representations and warranties of the Company contained in the Agreement and in any certificate or other writing delivered by the Company pursuant thereto that are qualified by Company Material Adverse Effect shall be true and correct in all respects both as of the date of the Agreement and as of the Offer Closing Date as though made on and as of the Offer Closing Date (except to the extent such representations and

A-1

warranties expressly relate to an earlier date, in which case such representations and warranties shall be true and correct in all respects on and as of such earlier date) and (B) the representations and warranties of the Company in the Agreement and in any certificate or other writing delivered by the Company pursuant thereto that are not so qualified shall be true and correct both as of the date of the Agreement and as of the Offer Closing Date as though made on and as of the Offer Closing Date (except to the extent such representations and warranties expressly relate to an earlier date, in which case such representations and warranties shall be true and correct on and as of such earlier date) except for such failures to be true and correct as have not resulted in or would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect;

(vi)                              The Company shall have performed in all material respects all obligations required to be performed by it under the Agreement at or prior to the Offer Closing Date;

(vii)                           The Company shall have delivered to Parent a certificate, signed by the chief executive officer and chief financial officer of the Company, to the effect that each of the conditions specified in (v) and (vi) above is satisfied;

(viii)                        The Company shall have delivered a duly executed FIRPTA Certificate;

(ix)                              There shall not be pending any suit, action or proceeding by any Governmental Entity seeking to prohibit or impose any material limitations on Parent’s ownership of the Company or the operation of all or a material portion of Parent’s or the Company’s businesses or assets (whether held directly or through Subsidiaries), or to compel Parent or the Company or any of their respective Subsidiaries to dispose of or hold separate any material portion of the business or assets of Parent or the Company (whether held directly or through Subsidiaries);

(x)                                 Since the date of the Agreement there shall not have been any occurrence, event, change, effect or development that, individually or in the aggregate, has had or is reasonably expected to have a Company Material Adverse Effect; and

(xi)                              the Company and Parent shall not have reached an agreement that the Offer or the Agreement be terminated, and the Agreement shall not have been terminated in accordance with its terms.

The foregoing conditions shall be in addition to, and not a limitation of, the rights of Parent and Merger Sub to extend, terminate and/or modify the Offer pursuant to the terms of the Agreement.

The foregoing conditions are for the benefit of Parent and Merger Sub, may be asserted by Parent or Merger Sub regardless of the circumstances giving rise to any such conditions and

A-2

may be waived by Parent or Merger Sub in whole or in part at any time and from time to time in their sole discretion (except for the Minimum Tender Condition), in each case, subject to the terms of the Agreement and the applicable rules and regulations of the SEC. The failure by Parent or Merger 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.
