RECITALS

WHEREAS, Parent desires to acquire the Company on the terms and subject to the conditions set forth in this Agreement;

WHEREAS, in furtherance of such acquisition, upon the terms and subject to the conditions set forth in this Agreement, Parent has agreed to cause Merger Sub to commence a tender offer (the "Offer") to purchase all of the issued and outstanding shares of common stock, par value $0.001 per share, of the Company (the "Company Common Stock") (which shares of the Company Common Stock are hereinafter referred to as the "Shares"), at a price per Share of $158.00 (such amount or any different amount per Share that may be paid pursuant to the Offer in accordance with the terms of this Agreement, the "Offer Price"), payable net to the holder in cash, without interest, subject to any withholding of Taxes required by applicable Law;

WHEREAS, following the acceptance for payment of Shares pursuant to the Offer, upon the terms and subject to the conditions set forth in this Agreement, Merger Sub will merge with and into the Company, with the Company continuing as the Surviving Corporation (the "Merger"), in accordance with the General Corporation Law of the State of Delaware (the "DGCL"), whereby each issued and outstanding Share (other than Shares to be cancelled in accordance with Section 2.1(b) and other than Dissenting Shares) will be converted into the right to receive the Offer Price, payable net to the holder in cash, without interest, subject to any withholding of Taxes required by applicable Law, such Merger to be effected pursuant to Section 251(h) of the DGCL as soon as practicable following the consummation of the Offer upon the terms and subject to the conditions set forth in this Agreement;

WHEREAS, the board of directors of the Company (the "Company Board") has (i) determined that the transactions contemplated by this Agreement, including the Offer and the Merger, are fair to and in the best interests of the Company and its stockholders, (ii) approved and declared advisable this Agreement and the transactions contemplated by this Agreement, including the Offer and the Merger and (iii) determined to recommend that the Company's stockholders accept the Offer and tender their Shares to Merger Sub in the Offer (the "Company Board Recommendation");

WHEREAS, the board of directors of Parent has approved this Agreement and the transactions contemplated by this Agreement, including the Offer and the Merger;

WHEREAS, the board of directors of Merger Sub has (i) determined that the transactions contemplated by this Agreement, including the Offer and the Merger, are fair to and in the best interests of Merger Sub and its sole stockholder, and (ii) approved and declared advisable this Agreement and the transactions contemplated by this Agreement, including the Offer and the Merger; and

WHEREAS, the Parties desire to make certain representations, warranties, covenants and agreements in connection with the Offer and the Merger and also to prescribe various conditions to the Offer and the Merger.

NOW, THEREFORE, in consideration of the mutual covenants and agreements contained in this Agreement and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the Parties agree as follows:

ARTICLE I

THE OFFER AND THE MERGER

1.1 The Offer.

(a) Provided that (i) this Agreement shall not have been terminated in accordance with Article VII, and (ii) all of the conditions set forth in paragraphs (c)(i) through (c)(vi) of Annex I shall then be satisfied (in the case of (x) paragraphs (c)(ii) through (c)(v), giving effect only to representations and warranties made as of dates prior to such time and (y) paragraph (c)(vi), giving effect only to agreements and covenants that the Company is required to comply with or to perform prior to such time) or waived by Parent or Merger Sub, as promptly as practicable (and in any event within ten 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, and the rules and regulations promulgated thereunder (the "Exchange Act"), the Offer to purchase all the outstanding Shares at the Offer Price.

(b) Subject to the satisfaction of the Minimum Condition and the satisfaction, or waiver by Merger Sub, of the other conditions set forth in Annex I, Merger Sub shall (and Parent shall cause Merger Sub to) accept for payment and pay for all Shares validly tendered and not properly withdrawn pursuant to the Offer as soon as practicable, but in any event no later than three Business Days, after the Expiration Date. The Offer Price payable in respect of each Share validly tendered and not properly withdrawn pursuant to the Offer shall be paid net to the holder in cash, without interest, subject to any withholding of Taxes required by applicable Law in accordance with Section 2.2(e).

(c) The Offer shall be made by means of an offer to purchase (the "Offer to Purchase") that describes the terms and conditions of the Offer in accordance with this Agreement, including the Minimum Condition and the other conditions set forth in Annex I. Merger Sub expressly reserves the right to increase the Offer Price or to make any other changes

in the terms and conditions of the Offer; provided, however, that unless otherwise expressly provided in this Agreement or as previously approved by the Company in writing, Merger Sub shall not, and Parent shall not permit Merger Sub to, (i) decrease the Offer Price, (ii) change the form of consideration payable in the Offer, (iii) reduce the maximum number of Shares to be purchased in the Offer, (iv) amend, modify or waive the Minimum Condition, (v) add any additional conditions to those set forth on Annex I or amend any of the conditions and requirements to the Offer set forth in Annex I in a manner adverse to the holders of Shares, (vi) extend the Expiration Date in a manner other than in accordance with this Agreement or (vii) otherwise amend, modify or supplement any of the terms of the Offer in a manner adverse to the holders of the Shares.

(d) Unless extended in accordance with the terms of this Agreement, the Offer shall expire at midnight (New York City time) on the date that is 20 Business Days following the commencement of the Offer (the "Initial Expiration Date") or, if the Initial Expiration Date has been extended in accordance with this Agreement, the date to which the Offer has been so extended (the Initial Expiration Date, or such later date to which the Initial Expiration Date has been extended in accordance with the terms of this Agreement, the "Expiration Date"). If on any then scheduled Expiration Date, all of the conditions to the Offer (including the Minimum Condition and the other conditions set forth in Annex I) have not been satisfied, or waived by Merger Sub, Merger Sub shall (and Parent shall cause Merger Sub to) extend the Offer for successive periods of up to ten Business Days each, the length of each such period to be determined by Parent in its sole discretion, in order to permit the satisfaction of such conditions; provided, however, that Merger Sub shall not be required to, and shall not without the Company's prior written consent, extend the Offer beyond August 20, 2015 (the "Outside Date"). In addition, Merger Sub shall extend the Offer for any period or periods required by applicable Law or applicable rules, regulations, interpretations or positions of the U.S. Securities and Exchange Commission (the "SEC") or its staff.

(e) Merger Sub shall not terminate the Offer prior to any scheduled Expiration Date without the prior written consent of the Company, except if this Agreement is terminated pursuant to Article VII. If this Agreement is terminated pursuant to Article VII, Merger Sub shall (and Parent shall cause Merger Sub to) promptly, irrevocably and unconditionally terminate the Offer. If the Offer is terminated or withdrawn by Merger Sub, or this Agreement is terminated prior to the purchase of Shares in the Offer, Merger Sub shall promptly (and in any event within two Business Days) return, and shall cause any depositary acting on behalf of Merger Sub to return, in accordance with applicable Law, all tendered Shares to the registered holders thereof.

(f) As soon as practicable on the date of the commencement of the Offer, Parent and Merger Sub shall file with the SEC, in accordance with Rule 14d-3 under the Exchange Act, a Tender Offer Statement on Schedule TO with respect to the Offer (together with all amendments, supplements and exhibits, the "Schedule TO"). The Schedule TO shall include, as exhibits, the Offer to Purchase, a form of letter of transmittal and a form of summary advertisement (collectively, together with any amendments and supplements, the "Offer Documents"). Parent and Merger Sub agree to cause the Offer Documents to be disseminated to holders of Shares, as and to the extent required by the Exchange Act. Parent and Merger 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 applicable Law, and Parent and Merger Sub agree to promptly 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 the Exchange Act. The Company and its counsel shall be given a reasonable opportunity to review the Schedule TO and the Offer Documents before they are filed with the SEC, and Parent and Merger Sub shall give due consideration to the reasonable additions, deletions or changes suggested by the Company and its counsel. In addition, Parent and Merger Sub shall provide the Company and its counsel with copies of any written comments, and shall inform them of any oral comments, that Parent, Merger Sub or their counsel may receive from time to time from the SEC or its staff with respect to the Schedule TO or the Offer Documents promptly after receipt of such comments, and any written or oral responses. The Company and its counsel shall be given a reasonable opportunity to review any such written responses and Parent and Merger Sub shall give due consideration to the reasonable additions, deletions or changes suggested by the Company and its counsel. The date and time at which Merger Sub accepts for payment Shares tendered and not properly withdrawn pursuant to the Offer is referred to in this Agreement as the "Acceptance Time."

(g) Parent shall provide or cause to be provided to Merger Sub on a timely basis the funds necessary to purchase any Shares Merger Sub becomes obligated to purchase pursuant to the Offer.

1.2 Company Actions.

(a) On the date of the filing of the Schedule TO, 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 with respect to the Offer (together with all amendments, supplements and exhibits, the "Schedule 14D-9") that shall, subject to the provisions of Sections 5.4(d)-(f), contain the Company Board Recommendation. The Company shall also include in the Schedule 14D-9, in their entirety, copies of the Fairness Opinions, together with summaries thereof in accordance with Item 1015(b) of Regulation M-A under the Exchange Act (regardless of whether such item is applicable). The Company consents to the inclusion in the Offer Documents of a description of the Company Board Recommendation. The Company further agrees to cause the Schedule 14D-9 to be disseminated to holders of Shares, as and to the extent required by the Exchange Act. The Company, on the one hand, and Parent and Merger Sub, on the other hand, agree to promptly correct 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 applicable Law, and the Company agrees to promptly cause the Schedule 14D-9, 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 the Exchange Act. Except with respect to any amendments filed after a Change of Board Recommendation (if there shall be one) or in connection with any disclosures made in compliance with Section 5.4(h): (i) Parent, Merger Sub and their counsel shall be given a reasonable opportunity to review the Schedule 14D-9 before it is filed with the SEC, and the Company shall give due consideration to the reasonable additions, deletions or changes suggested by Parent, Merger Sub and their counsel; (ii) the Company shall provide Parent, Merger Sub and their counsel with copies of any written comments, and shall inform them of any oral comments, 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 any written or oral responses; and (iii) Parent, Merger Sub and their counsel shall be given a reasonable opportunity to review any such written responses and the Company shall give due consideration to the reasonable additions, deletions or changes suggested by Parent, Merger Sub and their counsel.

(b) Promptly after the date of this Agreement and otherwise from time to time as requested by Merger Sub or its agents, the Company shall furnish or cause to be furnished to Merger Sub mailing labels, security position listings, non-objecting beneficial owner lists and any other listings or computer files containing the names and addresses of the record or beneficial holders of the Shares as of the most recent practicable date, and shall promptly furnish Merger Sub with such information (including updated lists of holders of the Shares and their addresses, mailing labels, security position listings and non-objecting beneficial owner lists) and such other assistance as Merger Sub or its agents may reasonably request in communicating with the record and beneficial holders of Shares. The foregoing information shall constitute Evaluation Material under the Confidentiality Agreement, and if this Agreement shall be terminated, upon request of the Company, Parent and Merger Sub shall destroy all copies of such information then in their possession or control pursuant to the terms of the Confidentiality Agreement. In addition, in connection with the Offer, unless there has been a Change of Board Recommendation, the Company shall, and shall use its reasonable best efforts to cause any third parties to, cooperate with Parent and Merger Sub to disseminate the Offer Documents to holders of Shares held in or subject to any Company Stock Plan or other Company Benefit Plan, and to permit such holders of Shares to tender Shares in the Offer.

1.3 The Merger.

(a) Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the DGCL, at the Effective Time, Merger Sub shall be merged with and into the Company. As a result of the Merger, the separate corporate existence of Merger Sub shall cease, and the Company shall continue as the surviving corporation of the Merger (the "Surviving Corporation"). The Merger shall have the effects set forth in the applicable provisions of the DGCL. Without limiting the generality of the foregoing, at the Effective Time, all of the property, rights, privileges, immunities, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation, and all of the debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

(b) At the Effective Time, the Company Certificate and Company Bylaws shall be amended and restated to be in the form of (except with respect to the name of the Company) the certificate of incorporation and bylaws, respectively, of Merger Sub and as amended shall be the certificate of incorporation and bylaws of the Surviving Corporation until thereafter amended as provided therein or by applicable Law, but in all events subject to Section 5.9 hereof.

(c) The directors of Merger Sub immediately prior to the Effective Time shall, from and after the Effective Time, be the initial directors of the Surviving Corporation, each to hold office in accordance with the certificate of incorporation and bylaws of the Surviving

Corporation until their respective successors shall have been duly elected, designated or qualified, or until their earlier death, resignation or removal in accordance with the certificate of incorporation and bylaws of the Surviving Corporation. The officers of Merger Sub immediately prior to the Effective Time, from and after the Effective Time, shall continue as the officers of the Surviving Corporation, each to hold office in accordance with the certificate of incorporation and bylaws of the Surviving Corporation until their respective successors shall have been duly elected, designated or qualified, or until their earlier death, resignation or removal in accordance with the certificate of incorporation and bylaws of the Surviving Corporation.

(d) The Merger shall be effected pursuant to, and governed by, Section 251(h) of the DGCL. The parties agree to take all necessary and appropriate action to cause the Merger to become effective as soon as practicable following the consummation of the Offer, without a meeting of stockholders of the Company in accordance with Section 251(h) of the DGCL.

(e) 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, instruments of conveyance, 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 Merger 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 Merger 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 of such corporations 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.

(b) On the Closing Date, or on such other date as Parent and the Company may agree to in writing, Parent, Merger Sub and the Company shall cause an appropriate certificate of merger or other appropriate documents (the "Certificate of Merger") to be executed and filed with the Secretary of State of the State of Delaware in accordance with the relevant provisions of the DGCL and shall make all other filings or recordings required under the DGCL. The Merger shall become effective at the time the Certificate of Merger shall have been duly filed with the Secretary of State of the State of Delaware or such later date and time as is agreed upon by the Parties and specified in the Certificate of Merger, such date and time hereinafter referred to as the "Effective Time".

ARTICLE II

CONVERSION OF SECURITIES IN THE MERGER

2.1 Conversion of Securities. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the holders of any of the following securities:

(a) Conversion of Company Common Stock. Each Share issued and outstanding immediately prior to the Effective Time, other than Shares to be cancelled in accordance with Section 2.1(b) and other than Dissenting Shares, shall be converted into the right to receive the Offer Price (the "Merger Consideration"), payable net to the holder in cash, without interest, subject to any withholding of Taxes required by applicable Law in accordance with Section 2.2(e).

(b) Cancellation of Treasury Stock and Parent-Owned Stock. All Shares that are held in the treasury of the Company or owned of record by any Company Subsidiary, and all Shares owned of record by Guarantor, Parent, Merger Sub or any of their respective wholly owned Subsidiaries shall be cancelled and shall cease to exist, with no payment being made with respect to such Shares.

(c) Merger Sub Common Stock. Each share of common stock, par value $0.001 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one newly and validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation.

(d) If, from and after the date of this Agreement until the Effective Time, the outstanding Shares are changed into a different number or class of shares by reason of any stock split, division, or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction, then the Merger Consideration shall be appropriately adjusted, but in no event shall the aggregate amount of Merger Consideration payable pursuant to this Agreement be increased or decreased due to such transaction.

2.2 Payment for Securities; Surrender of Certificates.

(a) Paying Agent. At or prior to the Effective Time, Parent shall designate a reputable bank or trust company reasonably acceptable to the Company to act as the paying agent (the "Paying Agent") for purposes of effecting the payment of (i) the Merger Consideration in connection with the Merger and (ii) the Option Payment payable to Non-Employee Holders. At or promptly after the Effective Time, Parent or Merger Sub shall deposit, or cause to be deposited, with the Paying Agent the aggregate Merger Consideration to which holders of Shares shall be entitled at the Effective Time pursuant to this Agreement and the aggregate Option Payments payable to Non-Employee Holders. Such funds shall be invested by the Paying Agent as directed by Parent, in its sole discretion, pending payment by the Paying Agent to the holders

of the Shares and the Non-Employee Holders. Earnings from such investments shall be the sole and exclusive property of Parent, and no part of such earnings shall accrue to the benefit of holders of Shares. In no event, however, shall any such investment or any such payment of earnings delay the receipt by former holders of Shares of the Merger Consideration or the receipt by Non-Employee Holders of the Option Payment or otherwise impair such holders' rights hereunder. To the extent that there are any losses with respect to any such investments or the fund diminishes for any reason below the level required for the Paying Agent to promptly pay the Merger Consideration and Option Payment to all those entitled thereto, Parent shall, or shall cause the Surviving Corporation to, promptly replace or restore the cash in such fund so as to ensure that such fund is at all times maintained at a level sufficient for the Paying Agent to make such payments.

(b) Procedures for Surrender. As promptly as practicable after the Effective Time, Parent or the Surviving Corporation shall cause the Paying Agent to mail to each holder of record of a certificate or certificates that represented Shares (the "Certificates") or non-certificated Shares represented by book-entry ("Book-Entry Shares"), in each case, which Shares were converted into the right to receive the Merger Consideration at the Effective Time pursuant to this Agreement: (i) a letter of transmittal, which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Paying Agent, and shall otherwise be in such form and have such other provisions as Parent and the Company 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 Certificates and Book-Entry Shares for cancellation to the Paying Agent or to such other agent or agents as may be appointed by Parent or the Surviving Corporation, and upon delivery of a letter of transmittal, duly executed and in proper form, with respect to such Certificates or Book-Entry Shares, the holder of such Certificates or Book-Entry Shares shall be entitled to receive the Merger Consideration for each Share formerly represented by such Certificates and for each Book-Entry Share. Any Certificates and Book-Entry Shares so surrendered shall be cancelled. If payment of the Merger Consideration is to be made to a Person other than the Person in whose name any surrendered Certificate is registered, it shall be a condition precedent of payment that the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer, and the Person requesting such payment shall have paid any transfer and other similar Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate so surrendered and shall have established to the satisfaction of the Surviving Corporation that such Taxes either have been paid or are not required to be paid. Payment of the Merger Consideration with respect to Book-Entry Shares shall only be made to the Person in whose name such Book-Entry Shares are registered. Until surrendered as contemplated hereby, each Certificate or Book-Entry Share 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 Agreement, without interest. Each Non-Employee Holder entitled to an Option Payment in accordance with Section 2.4 shall be entitled to receive such cash amount upon delivery of a properly completed letter of transmittal, which shall be provided to the Non-Employee Holders of Company Options at the same time letters of transmittal are provided to holders of Certificates and Book-Entry Shares. No interest shall be paid or will accrue on any cash payable to holders of Certificates or Book-Entry Shares pursuant to the provisions of this Article II.

(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 and Book-Entry Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares except as otherwise provided for in this Agreement or by applicable Law. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be cancelled and exchanged as provided in this Agreement.

(d) Termination of Fund; Abandoned Property; No Liability. At any time following twelve months after the Effective Time, Parent 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 to holders of Certificates or Book-Entry Shares (or Non-Employee Holders of Company Options), and thereafter such holders shall be entitled to look only to Parent (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 (or in the case of Non-Employee Holders of Company Options, the Option Payment) and compliance with the procedures in Section 2.2(b), without interest and subject to any withholding of Taxes required by applicable Law in accordance with Section 2.2(e). If, prior to six years after the Effective Time (or otherwise immediately prior to such time on which any payment would escheat to or become the property of any Governmental Entity pursuant to any applicable abandoned property, escheat or similar Laws), any holder of Certificates or Book-Entry Shares (or Non-Employee Holders of Company Options) has not complied with the procedures in Section 2.2(b) to receive payment of the Merger Consideration (or in the case of Non-Employee Holders of Company Options, the Option Payment) to which such holder would otherwise be entitled, the payment in respect of such Certificates or Book-Entry Shares (or in the case of Non-Employee Holders of Company Options, the Option Payment) 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. Notwithstanding the foregoing, to the fullest extent permitted by Law, neither the Surviving Corporation nor the Paying Agent shall be liable to any holder of a Certificate or Book-Entry Shares for Merger Consideration (or in the case of Non-Employee Holders of Company Options, the Option Payment) delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(e) Withholding Rights. Parent, Merger Sub, the Surviving Corporation and the Paying Agent, as the case may be, shall be entitled to deduct and withhold from the relevant Offer Price, Merger Consideration or Option Payment otherwise payable pursuant to this Agreement to any holder of Shares or Company Options, as applicable, such amounts that it is required to deduct and withhold with respect to the making of such payment under the Code, the rules and regulations promulgated thereunder or any provision of applicable state, local or foreign Law, including with respect to stock transfer Taxes payable by the holder. To the extent that amounts are so deducted and withheld by Parent, Merger Sub, the Surviving Corporation or the Paying Agent, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Shares or Company Options, as applicable, in respect of which such deduction and withholding was made by Parent, Merger Sub, the Surviving Corporation or the Paying Agent.

(f) Lost, Stolen or Destroyed Certificates. In the event that any Certificates shall have been lost, stolen or destroyed, the Paying Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, the Merger Consideration payable in respect thereof pursuant to Section 2.1(a); provided, however, that Parent may, in its discretion and as a condition precedent to the payment of such Merger Consideration, require the owners of such lost, stolen or destroyed Certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Parent, Merger Sub, the Surviving Corporation or the Paying Agent with respect to the Certificates alleged to have been lost, stolen or destroyed.

2.3 Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, Shares outstanding immediately prior to the Effective Time and held by a holder who is entitled to demand and has properly demanded appraisal for such Shares in accordance with, and who complies in all respects with, Section 262 of the DGCL (such Shares, the "Dissenting Shares") shall not be converted into the right to receive the Merger Consideration, and shall instead be entitled to payment of the fair value of such Dissenting Shares in accordance with and to the extent provided by Section 262 of the DGCL. If any such holder fails to perfect or otherwise waives, withdraws or loses his right to appraisal under Section 262 of the DGCL or other applicable Law, then the right of such holder to be paid the fair value of such Dissenting Shares shall cease and such Dissenting Shares shall be deemed to have been converted, as of the Effective Time, into and shall be exchangeable solely for the right to receive the Merger Consideration, without interest and subject to any withholding of Taxes required by applicable Law in accordance with Section 2.2(e). The Company shall give Parent prompt notice of any demands received by the Company for appraisal of Shares, attempted withdrawals of such demands and any other instruments served pursuant to the DGCL and received by the Company relating to rights to be paid the fair value of Dissenting Shares, and Parent shall have the right to participate in and to control all negotiations and proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, except with the prior written consent of Parent, make any payment with respect to, or settle or compromise or offer to settle or compromise, any such demands, waive any failure to timely deliver a written demand for appraisal in accordance with the DGCL or agree to do any of the foregoing.

excess, if any, of the Merger Consideration over the exercise price per Share previously subject to such Company Option (such amounts payable hereunder being referred to as the "Option Payments"). From and after the Effective Time, any such cancelled Company Option shall no longer be exercisable by the former holder thereof, but shall only entitle such holder to the payment of the Option Payment.

(b) Treatment of Restricted Stock. Prior to the Effective Time, the Company Board (or, if appropriate, any committee thereof) shall adopt appropriate resolutions and take all other actions necessary and appropriate to provide that, immediately prior to the Effective Time, each unvested Share subject to forfeiture restrictions, repurchase rights or other restrictions under the Company Stock Plans ("Company Restricted Stock") shall automatically become fully vested and then shall be cancelled at the Effective Time, and in exchange therefor, each former holder of such cancelled Company Restricted Stock shall be entitled to receive, in consideration of the cancellation of such Company Restricted Stock and in settlement therefor, a payment in cash (subject to any applicable withholding or other Taxes required by applicable Law to be withheld in accordance with Section 2.2(e)) equal to the per share Merger Consideration.

(i) No Company Benefit Plan is a multiemployer pension plan (as defined in Section 3(37) of ERISA) ("Multiemployer Plan") or other pension plan subject to Title IV of ERISA and neither the Company nor any ERISA Affiliate has sponsored or contributed to or been required to contribute to a Multiemployer Plan or other pension plan subject to Title IV of ERISA, and (ii) no material liability under Title IV of ERISA has been incurred by the Company or any ERISA Affiliate that has not been satisfied in full, and no condition exists that presents a material risk to the Company or any ERISA Affiliate of incurring or being subject (whether primarily, jointly or secondarily) to a material liability thereunder.

No payment or benefit provided pursuant to any Company Benefit Plan between the Company and any "service provider" (as such term is defined in Section 409A of the Code and the Treasury Regulations and IRS guidance thereunder), including the grant, vesting or exercise of any Company Option, will or may provide for the deferral of compensation subject to Section 409A of the Code, whether pursuant to the execution and delivery of this Agreement by the Company or the consummation of the transactions contemplated hereby (either alone or upon the occurrence of any additional or subsequent events) or otherwise. The Company is not a party to, or otherwise obligated under, any Company Benefit Plan that provides for the gross-up, indemnification or reimbursement of the Tax imposed by Section 409A(a)(1)(B) of the Code. The execution and delivery of this Agreement by the Company and the consummation of the transactions contemplated hereby will not (either alone or upon the occurrence of any additional or subsequent events) constitute an event under any Company Benefit Plan or Contract that will or may result in any payment of deferred compensation which will not be in compliance with Section 409A of the Code.

In the event that (i) a party other than Parent, Merger Sub or the Company or any of their Subsidiaries

makes a claim or takes other action to enforce any provision in this Agreement as an amendment to any Company Benefit Plan, and (ii) such provision is deemed to be an amendment to such Company Benefit Plan even though not explicitly designated as such in this Agreement, then such provision shall lapse retroactively and shall have no amendatory effect.

(b) Neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated hereby (either alone or in conjunction with any other event, such as termination of employment) will (i) result in any payment (including, without limitation, severance, unemployment compensation, parachute or otherwise) becoming due to any director, employee or consultant of the Company or any Company Subsidiary or affiliate, or to any Governmental Entity or other Person on behalf of any such director, employee or consultant, from the Company or any Company Subsidiary or affiliate under any Company Benefit Plan or otherwise, (ii) materially increase any benefits or amounts otherwise payable, or result in any other material obligation under any Company Benefit Plan, (iii) result in any acceleration of the time of payment or vesting of any compensation or benefits or result in the funding (through a grantor trust or otherwise) of any compensation or benefits under any Company Benefit Plan, (iv) limit or restrict the right of the Company or any Company Subsidiary, or, after the consummation of the transactions contemplated hereby, Parent or any Company Subsidiaries, to merge, amend, terminate or transfer the assets off any of the Company Benefit Plans, (v) result in payments under any of the Company Benefit Plans that would disqualify any amount from being qualified performance-based compensation within the meaning of Section 162(m) of the Code or (vi) result in any material breach or other material violation of or under any employment agreement, or any other labor-related agreement concerning the employees of the Company or any Company Subsidiary or to which any of the Company or any Company Subsidiary is party or by which such entity is bound.

(c) There are no pending or threatened claims (other than claims for benefits in the ordinary course), lawsuits or arbitrations which have been asserted or instituted against any Company Benefit Plan, any fiduciaries thereof with respect to their duties to the Company Benefit Plans or the assets of any of the trusts thereunder which would reasonably be expected to result in any material liability of the Company or any Company Subsidiary to the Pension Benefit Guaranty Corporation, the Department of Treasury, the Department of Labor or any Multiemployer Plan.

(d) Neither the Company nor any Company Subsidiary is a party to, or otherwise bound by, any collective bargaining agreement, contract or other written agreement or written understanding with a labor union, works council, employee representative or labor organization.

5.2 Financing.

(a) Each of Parent and Merger Sub shall, and shall cause each of its respective controlled affiliates to, use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to consummate and to obtain the Debt Financing on or prior to the Acceptance Time on the terms and conditions described in the Commitment Letter (including the exercise of any "market flex" provisions in the Fee Letter) and shall not permit any amendment, supplement, modification or replacement to be made to, or any waiver of any provision or any of its rights under, the Commitment Letter or the Definitive Agreements without the prior written consent of the Company (which consent shall not be unreasonably withheld, conditioned or delayed), if such amendment, supplement, modification, replacement or waiver (i) reduces the aggregate cash amount of proceeds of the Debt Financing to an amount below the amount (that when combined with the liquidity Parent then contemplates to be, and which is available to be, applied thereto) required to consummate the Offer, the Merger and the other transactions contemplated by this Agreement and to repay or refinance the debt contemplated to be replaced by the Commitment Letter, including the payment of all fees, premiums and expenses associated therewith, (ii) imposes new or additional conditions or any contingencies or otherwise expands upon, amends, supplements or otherwise modifies any of the conditions set forth in the Commitment Letter on the date hereof in a manner that would or would reasonably be expected to make a material portion of the Debt Financing less likely to be timely obtained (or the conditions to obtaining the Debt Financing less likely to be timely satisfied), (iii) prevents, materially impedes or materially delays the Closing, (iv) adversely impacts the ability of either Parent or Guarantor to enforce its rights against any other parties to the Commitment Letter or the Definitive Agreements in any material respect or (v) materially adversely impacts the ability of Parent or Merger Sub to consummate the Offer at the Acceptance Time, the Merger at the Closing or any of the other transactions contemplated by this Agreement. For the avoidance of doubt, Parent and Merger Sub may amend, supplement, modify or replace the Commitment Letter and the Fee Letter, in each case as in effect at the date hereto, or the Definitive Agreements, but only if any such amendment, supplement, modification or replacement is not inconsistent with the immediately preceding sentence, (w) to add or replace lenders, lead arrangers, bookrunners, syndication agents or similar entities which had not executed the Commitment Letter and the Fee Letter as of the date hereof, (x) to increase the amount of indebtedness, (y) to add or replace facilities with one or more new facilities or (z) otherwise in a manner not less favorable taken as a whole to Parent and Merger Sub. For purposes of this Agreement, (1) the term "Debt Financing" shall be deemed to include the Debt Financing, as amended, modified or replaced pursuant to this Section 5.2(a) and (2) the term "Commitment Letter" shall be deemed to include the Commitment Letter as it may be amended, supplemented, modified or replaced pursuant to this Section 5.2(a). Parent shall promptly deliver to the Company a true and complete copy of any such amendment, supplement, modification, replacement or waiver of the Commitment Letter or the Definitive Agreements.

(b) Each of Parent and Merger Sub shall, and shall cause each of its respective controlled affiliates to, use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to consummate and to obtain the Debt Financing on or prior to the Acceptance Time on the terms and conditions described in the Commitment Letter (including the exercise of any "market flex" provisions in the Fee Letter), including using reasonable best efforts to (i) comply with the terms and conditions of, and maintain in effect, the Commitment Letter pursuant to its terms (except for amendments, supplements, modifications and replacements made in compliance with Section 5.2(a)), (ii) negotiate and enter into, at or prior to the Acceptance Time, definitive agreements (such definitive agreements, the "Definitive Agreements") with respect to the Debt Financing (and promptly upon the execution and delivery thereof, provide true and complete copies of the Definitive Agreements to the Company) on the terms and conditions set forth in the Commitment Letter (including, if necessary, the exercise of "market flex" provisions in the Fee Letter) or on other terms and conditions that would not, if such other terms and conditions constituted an amendment to the Definitive Agreements, be inconsistent with Section 5.2(a), (iii) satisfy on a timely basis (or, if deemed advisable by Guarantor, seek a waiver on a timely basis of) all conditions and covenants applicable to Guarantor and Parent to the funding of the Debt Financing set forth in the Commitment Letter or the Definitive Agreements and (iv) if all conditions to the Debt Financing are, or upon funding of the Debt Financing will be, satisfied, cause the Financing Sources to comply with their obligations under the Commitment Letter and the Definitive Agreements and to fund at or prior to the Acceptance Time, the Debt Financing required to consummate the Offer at the Acceptance Time, the Merger at the Closing and the other transactions contemplated by this Agreement, including, if necessary, enforcing its rights under the Commitment Letter and the Definitive Agreements, provided however, under no circumstances shall Parent or Guarantor be required to commence or sustain legal proceedings in connection therewith.

(c) In the event that all or any portion of the Debt Financing becomes unavailable and such portion is reasonably required to consummate the Offer, the Merger and the other transactions contemplated by this Agreement, each of Guarantor and Parent shall use its reasonable best efforts to arrange and timely obtain substitute financing (on terms and conditions that are not materially less favorable to Guarantor and Parent, taken as a whole, than the terms and conditions set forth in the Commitment Letter relating to the Debt Financing to be replaced, taking into account the "market flex" provisions thereof) from the same or alternative sources in an amount sufficient to consummate Offer, the Merger and the other transactions contemplated by this Agreement (the "Substitute Financing") (and shall promptly upon the execution and delivery thereof, provide to the Company true and complete copies of the material, definitive documents related to the Substitute Financing (provided that, with respect to any fee letters, the fee amounts, pricing caps and other economic terms, and the rates and amounts included in the "market flex" provisions (but not covenants), may be redacted). All references to the term "Debt Financing" shall be deemed to include such Substitute Financing and all references to the "Commitment Letter," the "Fee Letter" and "Definitive Agreements" shall include the applicable documents for the Substitute Financing. Parent shall give the Company prompt written notice of any (i) material breach by any party to the Commitment Letter or the Definitive Agreements of which Parent or Merger Sub becomes aware or (ii) receipt by it of any written notice from any the Lenders or any other Financing Sources with respect to any actual or threatened withdrawal, repudiation or termination of the Debt Financing by the Lenders or any other Financing Sources. Parent shall keep the Company reasonably informed of the status of the efforts of Guarantor and Parent to arrange and obtain the Debt Financing.

(d) Prior to the Closing Date, the Company shall, and shall cause each of the Company Subsidiaries to, use its reasonable best efforts to, and the Company shall use its reasonable best efforts to cause its directors, officers, employees, accountants, consultants, legal counsel, advisors, agents and other representatives (collectively, "Company Representatives") to, provide to Parent and Merger Sub such cooperation as may be reasonably requested by Parent that is reasonably necessary or customary, proper or advisable in connection with the arrangement of the Debt Financing or any capital markets debt financing undertaken in replacement of all or any portion of the Debt Financing (the "Bond Financing", and together with the Debt Financing, the "Financing"), including (i) causing the Company Representatives to participate in meetings, presentations, road shows, due diligence sessions and meetings with, and presentations to, prospective Financing Sources, investors and rating agencies, in each case, upon reasonable advance notice and at times and locations to be mutually agreed, (ii) assisting Parent and the Financing Sources with the preparation of reasonable and customary materials for rating agency presentations, offering documents, syndication documents and materials, including private placement memoranda, bank information memoranda (confidential and public), offering memoranda, lender and investor presentations, prospectuses and similar documents reasonably required in connection with the Financing, in each case, including the execution and delivery of customary representation letters in connection therewith, (iii) as promptly as reasonably practicable, furnishing Parent and its Financing Sources with the Required Information and other financial and other information regarding the Company and the Company Subsidiaries as may be reasonably requested by Parent in connection with the Financing, (iv) assisting Parent with Parent's preparation of pro forma financial statements and financial information necessary to satisfy the conditions set forth in Section 2 of the Commitment Letter and Annex F thereto; provided that neither the Company nor any of the Company Subsidiaries or Company Representatives shall be responsible in any manner for information relating to the proposed debt and equity capitalization that is required for such pro forma financial information, (vi) cause the independent accountants of the Company to provide reasonable and customary assistance and cooperation in connection with the Financing, including (A) participating in a reasonable number of drafting sessions and accounting due diligence sessions, (B) rendering customary "comfort letters" (including customary "negative assurance" comfort and change period comfort) with respect to the financial information of the Company and the Company Subsidiaries contained in any materials relating to the Financing, including providing customary representations to such accountants, and (C) providing consents for use of their reports in any materials relating to the Financing and in connection with any filings required to be made by Parent pursuant to the Securities Act or the Exchange Act where financial information of the Company or any Company Subsidiary is included, (vii) executing and delivering (or using reasonable best efforts to obtain from its advisors) customary certificates, legal opinions or other documents and instruments as may be reasonably requested by Parent, as in each such case, necessary and customary in connection with the Financing, (viii) cooperating reasonably with the Financing Sources' due diligence, to the extent reasonable and customary, (ix) executing and delivering any customary pledge and security documents, other definitive financing documents, or other customary certificates, legal opinions or documents as may be reasonably requested by Parent and otherwise reasonably facilitating the pledging of collateral (including cooperation in connection with the pay-off of existing indebtedness, including the satisfaction and discharge at

the Closing of the Company's 6.00% Senior Notes due 2021, and the release of related liens); provided that the effectiveness of any definitive documentation executed by the Company or any Company Subsidiary shall be subject to the consummation of the Merger, (x) taking all actions reasonably necessary to permit the prospective Persons involved in the Financing to evaluate the Company, including the Company's current assets, cash management and accounting systems, policies and procedures relating thereto for the purposes of establishing collateral arrangements, in each case, upon reasonable advance notice and at times and locations to be agreed, (xi) using reasonable best efforts to obtain waivers, consents, estoppels and approvals from other parties to material leases, encumbrances and Contracts to which the Company or any Company Subsidiary is a party and to arrange discussions among Parent and its Financing Sources with other parties to material leases, encumbrances and Contracts, (xii) assisting Parent in obtaining corporate, credit, facility and securities ratings from rating agencies; (xiv) providing financial statements (including monthly financial statements) in the form and to the extent provided internally to senior management of the Company as promptly as reasonably practicable after providing such financial statements internally to senior management of the Company, (xv) furnishing Parent and any Financing Sources promptly, and in any event at least five days prior to the Closing Date, with all documentation and other information required by any Governmental Entity with respect to the Financing under applicable "know your customer" and anti-money laundering rules and regulations, including the USA PATRIOT Act of 2001, as amended, that has been reasonably requested not less than ten days prior to the Closing Date and (xvi) using its reasonable best efforts to take all actions necessary to permit the consummation of the Financing; provided, however, that nothing in this Section 5.2(d) shall require such cooperation to the extent it would (A) require the Company or any of the Company Subsidiaries to pay any fees, incur or reimburse any costs or expenses, or make any payment in connection with the Financing, prior to the occurrence of the Closing (except to the extent Parent promptly reimburses (in the case of ordinary course out-of-pocket costs and expenses) or provides the funding (in all other cases) to the Company or such Company Subsidiary therefor), or incur any liability in connection with the Financing that is effective prior to the occurrence of the Closing, or (B) require the Company or any of the Company Subsidiaries to enter into any instrument or Contract, or agree to any change or modification to any instrument or Contract, that is effective prior to the Closing or that would be effective if the Closing does not occur. The Company shall, and shall cause each of the Company Subsidiaries to, use its reasonable best efforts to periodically update any Required Information in order to ensure that the Required Information does not, when furnished and taken as a whole, contain any untrue statement of a material fact or omit to state any material fact, in each case with respect to the Company or the Company Subsidiaries, necessary in order to make the Required Information, in light of the circumstances under which the statements contained in the Required Information are made, not misleading. The Company consents to the use of its and the Company Subsidiaries' logos in connection with the Financing in a manner customary for such financing transactions; provided that such logos are used solely in a manner that is not intended to or reasonably likely to harm or disparage the Company or any of the Company Subsidiaries or the reputation or goodwill of the Company or any of the Company Subsidiaries.

(e) Parent shall promptly (i) upon request by the Company, reimburse the Company for all reasonable out of pocket costs (including reasonable outside attorneys' fees) incurred by the Company or any of the Company Subsidiaries or Company Representatives in connection with the cooperation of the Company and the Company Subsidiaries and the Company Representatives contemplated by this Section 5.2 and (ii) indemnify and hold harmless

the Company, the Company Subsidiaries and the Company Representatives from and against any and all liabilities, losses, damages, claims, costs, expenses, interest, awards, judgments and penalties suffered or incurred by any of them in connection with any claims asserted by the Lenders or any of the other Financing Sources in connection with the arrangement of the Financing (other than to the extent such liabilities, losses, damages, claims, costs, expenses, interest, awards, judgments or penalties arise from the willful misconduct or breach of this Section 5.2 by the Company, any Company Subsidiary or any Company Representative) and any information used in connection therewith (other than (x) arising from fraud, intentional misrepresentation, misstatements or omissions on the part of the Company or its affiliates or (y) written historical information of the type prepared by the Company or its affiliates in the ordinary course of business that is provided by the Company or any of its affiliates). All non-public or other confidential information provided by the Company to Parent, Parent Representatives or its Financing Sources pursuant to this Section 5.2 shall be kept confidential in accordance with the Confidentiality Agreement.

(f) Notwithstanding anything to the contrary contained in this Agreement, each of Parent and Merger Sub expressly acknowledges and agrees that Parent's and Merger Sub's obligations hereunder are not conditioned in any manner upon Parent or Merger Sub obtaining the Financing, any Substitute Financing or any other financing. The failure, for any reason, of Parent or Merger Sub to have sufficient cash available at the Acceptance Time to pay the consideration in the Offer in accordance with the Offer and this Agreement or at the Closing to pay the Merger Consideration in accordance with this Agreement or the failure to so pay the consideration in the Offer at the Acceptance Time in accordance with the Offer and this Agreement or the Merger Consideration at the Closing in accordance with this Agreement, in each case, shall constitute a breach of this Agreement by Parent and Merger Sub.

(g) Prior to or at the Closing, the Company shall deliver an executed payoff letter (the "Debt Payoff Letter") in form and substance reasonably satisfactory to Parent for the Credit Agreement, dated as of January 2, 2014, by and among the Company, as borrower, the lenders party thereto from time to time and Jefferies Finance LLC, as administrative agent and collateral agent, and the other agents party thereto (the "Credit Agreement"). The Debt Payoff Letter shall (A) confirm the full outstanding amount then outstanding, along with accrued interest thereon and all fees and other obligations of the Company accrued under the Credit Agreement, (B) contain payment instructions and (C) evidence the satisfaction, release and discharge of the debt and liabilities under the Credit Agreement and the agreement by such lenders to release all Liens upon the payment of such amount in accordance with the payment instructions. Prior to or at the Closing, the Company shall have obtained documents, including an authorization to file UCC termination statements upon such payment, executed terminations and releases of outstanding mortgages, as are reasonably necessary to release such Liens. The Company shall cooperate with Parent, upon Parent's reasonable request, so that the Company's 6.00% Senior Notes due 2021 may be satisfied and discharged at Closing, it being understood that (i) Parent shall deposit or cause to be deposited (including by means of the Company at Closing) the funds needed to satisfy and discharge such Notes, (ii) the Company shall not be required to deliver any notice of redemption to the Trustee or holders of such Notes prior to the Closing, and (iii) the Company shall not be required to take any action, to the extent it determines, after consultation with outside counsel, that such action would reasonably be likely to violate the terms of any Contract (including without limitation, the Company's outstanding indebtedness).

(a) From the date of this Agreement to the Effective Time and subject to applicable Law, the Company shall, and shall cause each Company Subsidiary and each of their respective Company Representatives to: (i) provide to Parent and Merger Sub and their respective officers, directors, employees, accountants, consultants, legal counsel, advisors, agents and other representatives (collectively, the "Parent Representatives") access at reasonable times upon prior reasonable notice to the officers, employees, agents, properties, offices and other facilities of such party and its Subsidiaries and to the books and records thereof (including Tax Returns) and (ii) furnish promptly such information concerning the business, properties, contracts, assets, liabilities, personnel and other aspects of such Party and its Subsidiaries as Parent or the Parent Representatives may reasonably request; provided that the Company shall not be required to provide any information relating to the negotiation or prosecution of this Agreement. None of the Company, any Company Subsidiary or any Company Representative shall be required to provide access to or disclose information where such access or disclosure would jeopardize the attorney-client privilege of the Company or its Subsidiaries or contravene any law, rule, regulation, order, judgment, decree or binding agreement entered into prior to the date of this Agreement; provided, however, that the Company shall inform Parent of the general nature of the information being withheld and the Parties shall make appropriate substitute disclosure arrangements under circumstances in which the restrictions of this sentence apply.

(b) With respect to the information disclosed pursuant to Section 5.3(a) or otherwise under this Agreement, Parent and Merger Sub shall comply with, and shall cause the Parent Representatives to comply with, all of their obligations under the Confidentiality Agreement, dated January 20, 2015, by and between the Company and Parent (the "Confidentiality Agreement"), which shall remain in full force and effect and is an integral part of the transactions contemplated by this Agreement.

(c) The Company shall provide Parent with a draft of its proposed Annual Report on Form 10-K for the fiscal year ended December 31, 2014, as soon as reasonably practicable after the date of this Agreement, and as reasonably far in advance of (and in any event at least five Business Days prior to) the filing thereof with the SEC. The Company shall give Parent a reasonable opportunity to review any material changes thereto before it is filed with the SEC and the Company shall give due consideration to the reasonable comments provided by Parent.

5.4 No Solicitation of Transactions.

(a) Subject to Section 5.4(b), from and after the date of this Agreement until the Effective Time or, if earlier, the termination of this Agreement in accordance with Article VII, the Company shall not, and shall cause the Company Subsidiaries and the Company Representatives not to, directly or indirectly: (i) initiate, solicit or knowingly encourage (including by way of providing information) or facilitate the submission of any inquiries, proposals or offers or any other efforts or attempts that constitute, or would reasonably be

expected to lead to, any Acquisition Proposal or engage in any discussions or negotiations or otherwise cooperate with or assist or participate in or facilitate any such inquiries, proposals, offers, discussions or negotiations, (ii) furnish to any Person any nonpublic information in connection with an Acquisition Proposal or any inquiry, proposal or offer that would reasonably be expected to lead to an Acquisition Proposal, (iii) approve or recommend, or publicly propose to approve or recommend, an Acquisition Proposal, (iv) withdraw, change, amend, modify or qualify, or propose publicly to withdraw, change, amend, modify or qualify, in a manner adverse to Parent or Merger Sub, the Company Board Recommendation, (v) enter into any merger agreement, letter of intent, agreement in principle, share purchase agreement, asset purchase agreement, share exchange agreement, option agreement or other agreement relating to an Acquisition Proposal or enter into any agreement or agreement in principle requiring the Company to abandon, terminate or fail to consummate the transactions contemplated hereby or breach its obligations hereunder, or (vi) resolve, propose or agree to do any of the foregoing (any action or failure to act set forth in the foregoing clauses (iii) or (iv), a "Change of Board Recommendation"). The Company shall immediately cease and cause to be terminated any activities, discussion or negotiation with any Persons conducted theretofore by the Company, the Company Subsidiaries or any Company Representatives with respect to any Acquisition Proposal and request to be returned or destroyed all confidential information provided by or on behalf of the Company or any Company Subsidiary to such Person.

(b) Notwithstanding anything to the contrary contained in Section 5.4(a), if at any time following the date of this Agreement and prior to the Acceptance Time (i) the Company has received an unsolicited bona fide written Acquisition Proposal from a third party, (ii)(A) such Acquisition Proposal (or any precursor thereto) did not result from a breach of this Section 5.4 and the Company has complied with the terms of this Section 5.4 in all respects with respect to such Acquisition Proposal (and any precursor thereto) and (B) the Company has not breached this Section 5.4 in any material respect, (iii) the Company Board determines in good faith, after consultation with its financial advisors of nationally recognized reputation (which Parent and Merger Sub acknowledge includes the Company Financial Advisors) and outside counsel, that such Acquisition Proposal constitutes or could reasonably be expected to result in a Superior Proposal and (iv) after consultation with its outside counsel, the Company Board determines in good faith that failure to take such action would be inconsistent with its fiduciary duties to the stockholders of the Company under applicable Law, then the Company and the Company Representatives may (A) furnish information with respect to the Company and the Company Subsidiaries to the Person making such Acquisition Proposal and (B) participate in discussions or negotiations with the Person making such Acquisition Proposal regarding such Acquisition Proposal; provided that the Company (x) will not, and will not allow the Company Subsidiaries and the Company Representatives to, disclose any nonpublic information to such Person without first entering into an Acceptable Confidentiality Agreement and (y) will promptly (and in no event later than 24 hours after providing such information) provide to Parent any information concerning the Company or the Company Subsidiaries provided to such other Person not previously provided to Parent.

(c) The Company shall promptly (and in any event within 24 hours) notify Parent in the event that the Company, any Company Subsidiary or any Company Representative receives (i) any Acquisition Proposal or indication by any Person that it is considering making an Acquisition Proposal, (ii) any request for non-public information relating to the Company or any

Company Subsidiary other than requests for information unrelated to an Acquisition Proposal or (iii) any inquiry or request for discussions or negotiations regarding any Acquisition Proposal. The Company shall notify Parent promptly (and in any event within 24 hours) of the identity of such Person and provide Parent a copy of such Acquisition Proposal, indication, inquiry or request (or, where no such copy is available, a reasonably detailed description of such Acquisition Proposal, indication, inquiry or request), including any modifications thereto. The Company shall keep Parent reasonably informed on a current basis (and in any event at Parent's request and otherwise no later than 24 hours after the occurrence of any changes, developments, discussions or negotiations) of the status of any Acquisition Proposal, indication, inquiry or request (including the terms and conditions thereof and of any modification thereto), and any material developments, discussions and negotiations. Without limiting the foregoing, the Company shall promptly (and in any event within 24 hours) notify Parent orally and in writing if it determines to begin providing information or to engage in discussions or negotiations concerning an Acquisition Proposal pursuant to Section 5.4(b).

(d) Notwithstanding anything to the contrary contained in Section 5.4(a), but subject to Section 5.4(f), if the Company receives an unsolicited Acquisition Proposal which the Company Board concludes in good faith, after consultation with outside counsel and its financial advisors, constitutes a Superior Proposal, after giving effect to all of the adjustments to the terms of this Agreement which may be offered by Parent (including pursuant to clause (ii) of Section 5.4(f) below), and so long as (A) such Acquisition Proposal (and any precursor thereto) did not result from a breach of this Section 5.4 and the Company has complied with the terms of this Section 5.4 in all respects with respect to such Acquisition Proposal (and any precursor thereto) and (B) the Company has not breached this Section 5.4 in any material respect, the Company Board may at any time prior to the Acceptance Time, if it determines in good faith, after consultation with outside counsel, that failure to take such action would be inconsistent with its fiduciary duties to the stockholders of the Company under applicable Law, (x) effect a Change of Board Recommendation with respect to such Superior Proposal and/or (y) terminate this Agreement to enter into a definitive agreement with respect to such Superior Proposal; provided, however, that the Company shall not terminate this Agreement pursuant to the foregoing clause (y), and any purported termination pursuant to the foregoing clause (y) shall be void and of no force or effect, unless in advance of or concurrently with such termination the Company pays or causes to be paid to Parent the Termination Fee and otherwise complies with the provisions of Section 7.1(e) and Section 7.2.

(e) Notwithstanding anything to the contrary contained in Section 5.4(a), but subject to Section 5.4(f), the Company Board may, at any time prior to the Acceptance Time, effect a Change of Board Recommendation for a reason unrelated to an Acquisition Proposal if the Company Board has determined in good faith, after consultation with its outside counsel, that, in light of material facts, events or circumstances that have arisen or occurred after the date of this Agreement that were not known by or reasonably foreseeable to the Company or the Company Board prior to the date hereof, other than (i) changes in the market price or trading volume of the Shares (however, the underlying reasons for such changes may constitute an Intervening Event), (ii) the timing of any consents, registrations, approvals, permits, clearances or authorizations required to be obtained prior to the Effective Time by the Company or Parent or any of their respective Subsidiaries from any Governmental Entity in connection with this Agreement and the consummation of the Offer, the Merger and the other transactions

contemplated hereby, (iii) an Acquisition Proposal, or an inquiry, proposal or offer that could reasonably be expected to lead to an Acquisition Proposal, or the consequences thereof, (iv) the fact that, in and of itself, the Company exceeds any internal or published industry analyst projections or forecasts or estimates of revenues or earnings (however, the underlying reasons for such events may constitute an Intervening Event) or (v) events set forth on Section 5.4(e) of the Company Disclosure Schedule (an "Intervening Event"), failure to take such action would be inconsistent with its fiduciary duties to the stockholders of the Company under applicable Law.

(f) The Company Board may not withdraw, modify or amend the Company Board Recommendation in a manner adverse to Parent pursuant to clause (x) of Section 5.4(d) or Section 5.4(e) or terminate this Agreement pursuant to clause (y) of Section 5.4(d) unless (A) in the case of actions taken in relation to a Superior Proposal, (1) such Superior Proposal (and any precursor thereto) did not result from a breach of this Section 5.4 and the Company has complied with the terms of this Section 5.4 in all respects with respect to such Superior Proposal (and any precursor thereto) and (2) the Company has not breached this Section 5.4 in any material respect, and (B) whether or not such action relates to a Superior Proposal:

(i) the Company shall have provided prior written notice to Parent, at least four Business Days in advance (the "Notice Period"), of its intention to take such action, which notice shall specify (A) if such action is to be taken in relation to a Superior Proposal, the material terms and conditions of such Superior Proposal (including the identity of the party making such Superior Proposal), and shall have contemporaneously provided a copy of the relevant proposed transaction agreements with the party making such Superior Proposal and other material documents, including the definitive agreement with respect to such Superior Proposal (the "Alternative Acquisition Agreement") or (B) if such action is to be taken in relation to an Intervening Event, a reasonably detailed description of the underlying facts giving rise to, and the reasons for taking, such action; and

(ii) prior to effecting such Change of Board Recommendation or terminating this Agreement to enter into a definitive agreement with respect to a Superior Proposal, the Company shall, and shall cause the Company Representatives to, during the Notice Period, negotiate with Parent in good faith (to the extent Parent desires to negotiate) to make such adjustments to the terms and conditions of this Agreement so that (A) if such action is to be taken in relation to a Superior Proposal, the Acquisition Proposal ceases to constitute a Superior Proposal or (B) if such action is to be taken in relation to an Intervening Event, the need for making a Change of Board Recommendation is obviated.

In the event of any revisions to the Superior Proposal or material developments in an Intervening Event, the Company shall be required to deliver a new written notice to Parent and to comply with the requirements of this Section 5.4(f) with respect to such new written notice; provided that the Notice Period shall be two Business Days in respect of such revisions.

(g) The Company agrees that any violation of the restrictions set forth in this Section 5.4 by any of the Company Representatives shall be deemed to be a breach of this Agreement (including this Section 5.4) by the Company.

(h) Nothing contained in this Section 5.4 or elsewhere in this Agreement shall prohibit the Company Board from disclosing to the stockholders of the Company a position contemplated by Rule 14e-2(a) and Rule 14d-9 promulgated under the Exchange Act.

5.5 Reasonable Best Efforts.

(a) Each of the Company, Parent and Merger Sub shall use its reasonable best efforts to, and shall use its reasonable best efforts to cause each of the Company Representatives (in the case of the Company) and each of the Parent Representatives (in the case of Parent and Merger Sub) to, (i) take, or cause to be taken, all actions, and do, or cause to be done, and cooperate with the other Parties in doing, all things necessary, proper or advisable under applicable Law or otherwise to consummate and make effective the Offer, the Merger and each of the other transactions contemplated by this Agreement as promptly as practicable after the date of this Agreement, (ii) take, or cause to be taken, all actions consistent with this Section 5.5(a) necessary to cause the expiration or termination of the applicable waiting period under the HSR Act (including any extensions thereof) as soon as practicable after the date of this Agreement, (iii) cause each of the conditions to the Offer set forth in Annex I and each of the conditions to the Merger set forth in Section 6.1 to be satisfied as promptly as practicable after the date of this Agreement, (iv) obtain, as promptly as practicable after the date of this Agreement, from any Governmental Entities, and maintain, any consents, licenses, permits, waivers, approvals, authorizations or orders required to be obtained by Parent or the Company or any of their respective Subsidiaries, or to avoid or resolve any action or proceeding by any Governmental Entity (including those in connection with the HSR Act or any other antitrust or competition Law), in connection with the authorization, execution and delivery of this Agreement and the consummation of the transactions contemplated hereby, including the Offer and the Merger, (v) as promptly as practicable (and in any event within ten Business Days, unless otherwise agreed by the Parties) after the date of this Agreement, make all necessary filings with respect to this Agreement, the Offer and the Merger as required under the HSR Act, and (vi) as promptly as practicable after the date of this Agreement, make all necessary filings (and thereafter make any other required submissions and supply any additional information and documentary material that may be requested by any Governmental Entity), and pay any fees due in connection therewith, with respect to this Agreement, the Offer and the Merger required under (A) the Exchange Act, and any other applicable federal or state securities Laws, and (B) any other applicable Law, including any other antitrust or competition Law; provided, that each of the Company, Parent and Merger Sub shall cooperate with the other Parties in connection with (x) preparing and filing the Offer Documents, the Schedule 14D-9 and any Other Filings, (y) determining whether any action by or in respect of, or filing with, any Governmental Entity is required, in connection with the consummation of the Offer, the Merger or any of the other transactions contemplated by this Agreement and (z) seeking any such actions, consents, approvals or waivers or making any such filings. The Company, Parent and Merger Sub shall promptly furnish to each other all information required for any application or other filing under the rules and regulations of any applicable Law in connection with the Offer, the Merger or any of the other transactions contemplated by this Agreement.

(b) At Parent's request, the Company shall give (or shall cause the Company Subsidiaries to give) any notices to third parties, and use, and cause the Company Subsidiaries to use, their reasonable best efforts to obtain any third party consents, approvals or waivers required to be obtained under Company Material Contracts or other Contracts in connection with consummation of the Offer, the Merger or any of the other transactions contemplated by this Agreement. The Company shall coordinate and cooperate with Parent in determining whether any actions, consents, approvals or waivers are required to be obtained from parties to any Company Material Contracts in connection with consummation of the Offer, the Merger or any of the other transactions contemplated by this Agreement and seeking any such actions, consents, approvals or waivers. Notwithstanding the foregoing, neither the Company nor any Company Subsidiaries shall pay any consideration or make any agreements or commitments in connection with any such consents, approvals or waivers without the prior written consent of Parent.

(c) Parent shall, on behalf of the Parties, control and lead all communications with any Governmental Entity relating to antitrust or other competition Laws, and determine and direct the strategy and process by which the Parties will seek required approvals relating to antitrust and other competition Laws, subject to good faith consultations with the Company and its compliance with this Section 5.5. In furtherance and not in limitation of the foregoing, Parent shall consult with the Company and consider in good faith the views of the Company prior to proposing, negotiating, or entering into any agreement, undertaking or understanding (whether oral or written) with any Governmental Entity relating to any antitrust or other competition Laws, provided that the final determination as to the appropriate course of action shall be made by Parent. In the event that the Parties do not agree with respect to any matter in connection with seeking required approvals relating to antitrust or other competition Laws, subject to and without limiting in any respect the Parties' obligations in this Section 5.5, Parent's decision will control.

(d) In furtherance and not in limitation of the foregoing, each Party shall: (i) give the other Parties prompt notice of the making or commencement of any request, inquiry, investigation, action or legal proceeding by or before any Governmental Entity with respect to the Offer, the Merger or any of the other transactions contemplated by this Agreement, (ii) keep the other Parties informed as to the status of any such request, inquiry, investigation, action or legal proceeding and (iii) promptly inform the other Parties of any communication to or from the Federal Trade Commission, the Department of Justice or any other Governmental Entity regarding the Offer, the Merger or any of the other transactions contemplated by this Agreement. Each Party will consult and cooperate with the other Parties and will consider in good faith the views of the other Parties in connection with any filing, analysis, appearance, presentation, memorandum, brief, argument, opinion or proposal made or submitted in connection with the Offer, the Merger or any of the other transactions contemplated by this Agreement. In addition, except as may be prohibited by any Governmental Entity or by any Law, in connection with any such request, inquiry, investigation, action or legal proceeding, each Party will permit authorized representatives of the other Parties to be present at each meeting or conference relating to such request, inquiry, investigation, action or legal proceeding and to have access to and be consulted in connection with any document, opinion or proposal made or submitted to any Governmental Entity in connection with such request, inquiry, investigation, action or legal proceeding.

(e) In furtherance and not in limitation of the foregoing, and notwithstanding anything to the contrary set forth in this Agreement, Parent shall, and shall cause each of its Subsidiaries to, take any and all steps necessary to avoid and eliminate each and every impediment under any antitrust or competition Law that may be asserted by any Governmental Entity or any other Person so as to enable the Parties to consummate the Offer, the Merger and the other transactions contemplated by this Agreement as soon as practicable after the date of this Agreement (but in any event not later than the Outside Date), including proposing, negotiating, effecting and agreeing to, by consent decree, hold separate order or otherwise, any sale, divestiture, license, holding separate or other similar arrangement with respect to, or other disposition of or restriction on, any or all of Parent's or the Company's respective businesses, product lines, divisions or assets or interests therein, and taking such action or actions that would in the aggregate have a similar effect, including agreeing to change or modify, and changing or modifying, any course of conduct regarding their respective future operations or otherwise taking actions that would limit their respective freedom of action with respect to, or ability to retain, one or more of their respective businesses, product lines, divisions or assets or interests therein. Parent shall take any and all actions necessary in order to ensure that (x) no requirement for non-action, a waiver, consent or approval of the United States Federal Trade Commission, the Antitrust Division of the United States Department of Justice, any State Attorney General or other Governmental Entity, (y) no decree, judgment, injunction, temporary restraining order or any other order in any suit or proceeding, and (z) no other matter relating to any antitrust or competition Law, would preclude satisfaction of the Offer conditions by the Outside Date. The Company shall agree if, but solely if, requested by Parent so as to permit the expiration or termination of the applicable waiting periods under the HSR Act or the receipt of any other approval or the expiration or termination of any applicable waiting period under any other antitrust or competition Law, in each case as soon as practicable after the date of this Agreement (but in any event not later than necessary to satisfy the HSR Condition in Annex I at least three Business Days prior to the Expiration Date), to effect and agree to any sale, divestiture, license, holding separate or other similar arrangement with respect to, or other disposition of or restriction on, any of its businesses, product lines, divisions or assets or interests therein, and take such action or actions that would in the aggregate have a similar effect; provided, however, that any such sale, divestiture, license, holding separate or other similar arrangement, disposition, restriction or action or actions is conditioned on the occurrence of, and shall become effective only from and after, the Effective Time.

(f) Parent shall not, and it shall cause its Subsidiaries not to, directly or indirectly, acquire, purchase, lease or license (or agree to acquire, purchase, lease or license), by merging with or into or consolidating with, or by purchasing a substantial portion of the assets of or equity in, or by any other manner, any business or any corporation, partnership, association or other business organization or division or part thereof, or any securities or collection of assets, if doing so would reasonably be expected to: (i) impose any material delay in the obtaining of, or materially increase the risk of not obtaining, any consent, approval or exemption of any Governmental Entity necessary to consummate the Offer, the Merger and the other transactions contemplated by this Agreement or the expiration or termination of any applicable waiting period under applicable Law; (ii) materially increase the risk of any Governmental Entity entering any judgment, decree, injunction or other order prohibiting the Offer, the Merger or any of the other transactions contemplated by this Agreement; (iii) materially increase the risk of not being able to remove any such judgment, decree, injunction or other order on appeal or otherwise; or (iv) restrict, prevent, prohibit, impede or delay the consummation of the Offer, the Merger or any of the other transactions contemplated by this Agreement.

(g) In furtherance and not in limitation of the foregoing, in the event that any litigation or other administrative or judicial action or proceeding is commenced, threatened or is reasonably foreseeable that seeks, or would reasonably be expected to seek, to restrict, prevent, prohibit, impede or delay the consummation of the Offer, the Merger or any of the other transactions contemplated by this Agreement, each of Parent and the Company shall, and shall cause each of their respective Subsidiaries to, use its reasonable best efforts to take all actions, and do all things necessary, proper or advisable, and cooperate with each other, to contest and resist any such litigation, action or proceeding, including through litigation on the merits and appeal, and to, as applicable, avoid the entry of, or have vacated, lifted, reversed or overturned, any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that is in effect and that restricts, prevents, prohibits, impedes or would have the effect of delaying the consummation of the Offer, the Merger or any of the other transactions contemplated by this Agreement, in any case as promptly as practicable and in any event no later than necessary to satisfy the HSR Condition in Annex I at least three Business Days prior to the Outside Date. In furtherance and not in limitation of the foregoing, in the event that any such litigation, action or proceeding is commenced against Parent or the Company (or any of their respective directors or Subsidiaries), or any such litigation, action or proceeding is, to the knowledge of Parent or the Company, as the case may be, threatened or reasonably foreseeable, Parent or the Company, as the case may be, shall promptly inform the other Party thereof in writing and shall provide the other Party with such updates and such information as the other Party shall reasonably request with respect to such litigation, action or proceeding, and the status thereof, provided, however, that neither Parent nor the Company shall be required to disclose any information if such disclosure would, in the opinion of its outside counsel, jeopardize any attorney-client or other legal privilege; provided further that the Parties shall use reasonable best efforts to enable such information to be furnished or made available to the other Party without jeopardizing privilege, including by entering into a customary joint defense agreement or common interest agreement.

(h) In furtherance and not in limitation of the foregoing, each of Parent, Merger Sub and the Company shall provide such information and execute such further instruments and written assurances as may be reasonably requested by the other Parties and assist and cooperate with the other Parties, in each case in accordance with the provisions of this Agreement, in order to carry into effect the intents and purposes of, and to consummate the transactions contemplated by, this Agreement as promptly as practicable after the date of this Agreement.

5.6 Certain Notices. From and after the date of this Agreement until the Effective Time, each of the Company and Parent shall promptly notify the other Party of (a) the occurrence, or non-occurrence, of any event that would be likely to cause any condition to the obligations of any Party to effect the Offer, the Merger or any other transaction contemplated by this Agreement not to be satisfied or (b) the failure of the Company or Parent, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it pursuant to this Agreement which would reasonably be expected to result in any condition to the obligations of any Party to effect the Offer, the Merger or any other transaction

contemplated by this Agreement not to be satisfied; provided, however, that the delivery of any notice pursuant to this Section 5.6 shall not cure any breach of any representation, warranty, covenant or agreement contained in this Agreement or otherwise limit or affect the remedies available hereunder to the Party receiving such notice. The failure to deliver any notice pursuant to this Section 5.6 shall not affect any of the conditions to the Offer or the Merger or give rise to any right to terminate this Agreement pursuant to Article VII.

5.7 Public Announcements. The Company, Parent and Merger Sub agree that the press release announcing the execution and delivery of this Agreement shall be a joint release of, and shall not be issued prior to the approval of each of, the Company and Parent. All formal written communications to the officers or employees of the Company and any Company Subsidiaries pertaining to compensation or benefit matters that are affected by the transactions contemplated by this Agreement shall be subject to Parent's prior consent (not to be unreasonably withheld or delayed). The Company shall provide Parent with a copy of the intended communication, and Parent shall have a reasonable period of time to review and comment on each such communication (not to be unreasonably withheld or delayed). Any group oral presentations with respect to the above shall be materially consistent with such formal written communications.

5.8 Employee Benefit Matters.

(a) For purposes of this Section 5.8, (i) the term "Company Employees" shall mean employees who are actively employed by the Company or its Subsidiaries at the Effective Time and who remain employed by Parent or a Subsidiary thereof following the Closing Date, and (ii) the term "Continuation Period" shall mean the period beginning at the Effective Time and ending on the first anniversary of the Effective Time. For the Continuation Period, Parent shall provide, or shall cause the Surviving Corporation to provide, to each Company Employee, compensation and benefits that are no less favorable in the aggregate to either those compensation and benefits that are generally made available by the Company to such Company Employees immediately prior to the Effective Time or to similarly situated employees of Parent, as determined by Parent in its sole discretion. Except as expressly provided herein, nothing herein is intended to limit the right of Parent or the Surviving Corporation to (i) terminate the employment of any Company Employee at any time, (ii) change or modify any incentive compensation or employee benefit plan or arrangement at any time and in any manner, or (iii) change or modify the terms or conditions of employment for any of their employees.

(b) With respect to any compensation or benefit plans sponsored by Parent or its affiliates (each a "Parent Benefit Plan") in which any Company Employee who remains employed by Parent or a Subsidiary thereof will participate effective as of or after the Effective Time, Parent shall, or shall cause the Surviving Corporation to, use reasonable best efforts to (i) waive all preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to any Company Employee under any Parent Benefit Plan that is a welfare plan to the extent they were inapplicable to, or satisfied under, the Company Benefit Plans in which any such employee participated immediately prior to the Effective Time, (ii) cause the eligible expenses incurred by each Company Employee under any Company Benefit Plan during the portion of the plan year ending on the Closing Date to be taken into account for purposes of satisfying any applicable deductible or out-of-pocket requirements under the

corresponding Parent Benefit Plan that is a welfare plan, to the extent that such employee would have received credit for such co-payment or deductible under the corresponding Company Benefit Plan in which the applicable employee participated immediately prior to the Effective Time, and (iii) recognize the service of each Company Employee with the Company and its Subsidiaries prior to the Closing Date for purposes of eligibility and vesting (but not benefit accruals) under each Parent Benefit Plan in which Company Employees are eligible to participate after the Effective Time to the same extent such service was credited under the Company Benefit Plans (except to the extent such service credit will result in the duplication of benefits).

(c) Notwithstanding anything herein to the contrary, any Company Employee who terminates employment during the period beginning on the Effective Time and ending on the first anniversary thereof shall be entitled to severance pay and benefits no less favorable in the aggregate than the severance pay and benefits such Company Employee would have been entitled to pursuant to the severance plans and arrangements set forth on Section 5.8(c) of the Company Disclosure Schedule had such termination of employment occurred immediately prior to the Effective Time.

(d) With respect to each Company Employee with an employment agreement identified on Section 3.12(a) of the Company Disclosure Schedule, Parent agrees to honor or cause to be honored the terms of each such employment agreement through the expiration, modification or termination of such agreements in conformity with applicable Law.

(e) The Company, Parent and Merger Sub acknowledge and agree that all provisions contained in this Section 5.8 with respect to employees are included for the sole benefit of the respective parties to this Agreement and shall not create any third-party beneficiary rights in any other Person, including any Company Employees, former employees, any participant in any Company Benefit Plan or any beneficiary or dependent thereof. The Company, Parent and Merger Sub further acknowledge and agree that no provisions of this Agreement (including the provisions contained in this Section 5.8) shall (i) be construed to (x) establish, amend, or modify a Company Benefit Plan or any other benefit plan, program, agreement or arrangement (including any Parent Benefit Plan), (y) require Parent or the Surviving Corporation to continue or amend any Company Benefit Plan, Parent Benefit Plan or any other particular benefit plan after the consummation of the transactions contemplated by this Agreement or (z) prevent or limit Parent from terminating or modifying any Parent Benefit Plan, Company Benefit Plan or other employee benefit plan that Parent may establish or maintain (in accordance with its respective terms) or (ii) require Parent to continue or maintain the employment of any Company Employee following the Closing Date.

5.9 Indemnification of Directors and Officers.

(a) All rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time (and rights to advancement of expenses) now existing in favor of any Person who is or prior to the Effective Time becomes, or has been at any time prior to the date of this Agreement, a director, officer, employee or agent (including as a fiduciary with respect to an employee benefit plan) of the Company, any of the Company Subsidiaries or any of their respective predecessors as provided in the Company Certificate, the

Company Bylaws, the organizational documents of any Company Subsidiary or any indemnification agreement between such Indemnified Party and the Company or any of the Company Subsidiaries in effect as of the date hereof (i) shall survive the Merger, (ii) shall continue in full force and effect in accordance with their terms with respect to any claims against any such Person arising out of such acts or omissions and (iii) shall not be amended, repealed or otherwise modified in any manner that would adversely affect any right thereunder of any such Person. Parent shall ensure that the Surviving Corporation complies with and honors the foregoing obligations.

(b) Without limiting Section 5.9(a) or any rights of any individual who is a member of the Company Board or an officer of the Company as of the date hereof, or who becomes a member of the Company Board or an officer of the Company prior to the Effective Time (an "Indemnified Party"), pursuant to any indemnification agreement, from and after the acceptance for payment of, and payment by Merger Sub for, any Shares pursuant to the Offer, in the event of any threatened or actual action, suit, claim, proceeding, investigation, or arbitration (each an "Indemnified Proceeding"), whether civil, criminal or administrative, by reason of (i) the fact that the Indemnified Party is or was a director, officer, employee or agent (including as a fiduciary with respect to an employee benefit plan) of the Company, any of the Company Subsidiaries or any of their respective predecessors, or is or was serving at the request of the Company as a director, officer, employee or agent of another Person or (ii) this Agreement or any of the transactions contemplated hereby, whether in any case asserted or arising before or after the Effective Time, the Surviving Corporation shall indemnify and hold harmless, as and to the fullest extent permitted by applicable Law, each such Indemnified Party against any losses, claims, damages, liabilities, costs, expenses (including reasonable attorney's fees and expenses in advance of the final disposition of any Indemnified Proceeding to each Indemnified Party to the fullest extent permitted by applicable Law upon receipt of any undertaking required by applicable Law), judgments, fines and amounts paid in settlement of or in connection with any such threatened or actual Indemnified Proceeding. Any Indemnified Party wishing to claim indemnification under this Section 5.9, upon learning of any such Indemnified Proceeding, shall promptly notify Parent thereof, but the failure to so notify shall not relieve the Surviving Corporation of any liability it may have to such Indemnified Party except to the extent such failure materially prejudices the indemnifying party. In the event of any such Indemnified Proceeding (whether arising before or after the Effective Time), (i) Parent or the Surviving Corporation shall have the right to assume the defense thereof and Parent and the Surviving Corporation shall not be liable to such Indemnified Parties for any legal expenses of other counsel subsequently incurred by such Indemnified Parties in connection with the defense thereof, except that if Parent or the Surviving Corporation elects not to assume such defense or counsel for the Indemnified Parties advises that there are issues which raise conflicts of interest between Parent or the Surviving Corporation and the Indemnified Parties, the Indemnified Parties may retain counsel satisfactory to them, and Parent or the Surviving Corporation shall pay all reasonable fees and expenses of such counsel for the Indemnified Parties promptly as statements therefor are received; provided, however, that Parent and the Surviving Corporation shall be obligated pursuant to this paragraph (b) to pay for only one firm of counsel for all Indemnified Parties in any jurisdiction unless the use of one counsel for such Indemnified Parties would present such counsel with a conflict of interest, provided that the fewest number of counsels necessary to avoid conflicts of interest shall be used; (ii) the Indemnified Parties will cooperate in the defense of any such matter at Parent's or the Surviving Corporation's expense;

and (iii) Parent and the Surviving Corporation shall not be liable for any settlement effected without their prior written consent; and provided, further, that Parent and the Surviving Corporation shall not have any obligation hereunder to any Indemnified Party if and when a court of competent jurisdiction shall ultimately determine, and such determination shall have become final and nonappealable, that the indemnification of such Indemnified Party in the manner contemplated hereby is prohibited by applicable Law. Parent's and the Surviving Corporation's obligations under this Section 5.9(b) shall continue in full force and effect for the period beginning upon the acceptance for payment of, and payment by Merger Sub for, any Shares pursuant to the Offer and ending six years from the Effective Time; provided, however, that all rights to indemnification in respect of any Indemnified Proceeding asserted or made within such period shall continue until the final disposition of such Indemnified Proceeding.

(c) For the period beginning upon the acceptance for payment of, and payment by Merger Sub for, any Shares pursuant to the Offer and ending six years after the Effective Time, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, maintain for the benefit of each Indemnified Party an insurance and indemnification policy that provides coverage for events occurring at or prior to the Effective Time (the "D&O Insurance") that contains terms (including with respect to coverage and amounts) and conditions (including with respect to deductibles and exclusions) that are, individually and in the aggregate, no less favorable to any Indemnified Party than those of the Company's directors' and officers' liability insurance policies in effect on the date of this Agreement or, if such insurance coverage is unavailable, the best available coverage; provided, however, that the Surviving Corporation shall not be required to pay a premium for the D&O Insurance in excess of 300% of the last annual premium paid prior to the date of this Agreement (the "Maximum Amount"); provided further that if the amount of annual premiums necessary to maintain or procure such insurance coverage exceeds the Maximum Amount, Parent and the Surviving Corporation shall procure and maintain for such six-year period the most advantageous policy available for an annual premium equal to the Maximum Amount. The provisions of the immediately preceding sentence shall be deemed to have been satisfied if prepaid policies have been obtained by the Company prior to the Effective Time, which policies provide such directors and officers with coverage for an aggregate period of six years with respect to claims arising from facts or events that occurred at or before the Effective Time, including in respect of the transactions contemplated by this Agreement. If such prepaid policies have been obtained prior to the Effective Time, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, maintain such policies in full force and effect and comply with all obligations thereunder.

(d) The obligations under this Section 5.9 shall not be terminated or modified in such a manner as to adversely affect any Indemnified Party without the written consent of such affected Indemnified Party (it being expressly agreed that the Indemnified Parties shall be third party beneficiaries of this Section 5.9).

(e) In the event that the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all its properties and assets to any Person, or if Parent dissolves or liquidates the Surviving Corporation, then, and in each such case, Parent shall cause proper provision to be made so that the successors and assigns of the Surviving Corporation assume the obligations set forth in this Section 5.9.

5.10 State Takeover Laws. If any "control share acquisition", "fair price", "business combination" or other anti-takeover Law becomes or is deemed to be applicable to the Company, Parent or Merger Sub, the Offer, or the Merger, including the acquisition of Shares pursuant thereto, or any other transaction contemplated by this Agreement, then the Company Board shall take all action necessary to render such Law inapplicable to the foregoing.

5.11 Section 16 Matters. Prior to the Effective Time, the Company Board, or an appropriate committee of non-employee directors, shall adopt a resolution consistent with the interpretive guidance of the SEC so that the disposition by any officer or director of the Company who is a covered Person of the Company for purposes of Section 16 of the Exchange Act and the rules and regulations thereunder ("Section 16") of Shares or Company Options pursuant to this Agreement, the Offer and the Merger shall be an exempt transaction for purposes of Section 16.

5.12 Rule 14d–10(d) Matters. Prior to the Acceptance Time, the Company (acting through the Compensation Committee of the Company Board) will take all such steps as may be required to cause each agreement, arrangement or understanding entered into by the Company or the Company Subsidiaries on or after the date of this Agreement with any of its officers, directors or employees pursuant to which consideration is paid to such officer, director or employee to be approved as an "employment compensation, severance or other employee benefit arrangement" within the meaning of Rule 14d–10(d)(1) under the Exchange Act and to satisfy the requirements of the non-exclusive safe harbor set forth in Rule 14d–10(d) under the Exchange Act. Promptly upon Parent or any of its affiliates entering into any such arrangement with any current or future director, officer or employee of the Company or any of the Company Subsidiaries, Parent will provide to the Company any and all information concerning such arrangements as may be needed by the Company to comply with this Section 5.12.

5.13 Company Convertible Debt.

(a) Prior to the Effective Time, the Company shall take all necessary action to enter into one or more supplemental indentures, executed and delivered to the Trustee at or prior to the Effective Time and satisfactory in form and substance to the Trustee (as defined in each of the indentures under which each series of notes of Company Convertible Debt (each, a "Convertible Senior Note") was issued (the "Indentures")), to each Indenture to provide for the conversion and settlement of the Convertible Senior Notes following the Effective Time, as set forth in the respective Indentures governing the conversions of the Convertible Senior Notes issued thereunder (including any applicable increase in the "Conversion Rate" thereunder in connection with the Offer and the Merger) and changes to the consideration deliverable to holders upon conversion thereof, if, with respect to either Indenture, any Convertible Senior Notes issued thereunder will remain outstanding as of the Effective Time.

(b) Prior to the Effective Time, the Company shall take all such actions as may be required in accordance with, and subject to, the terms of the applicable Indenture or under applicable Law, including, without limitation, the giving of any notices that may be

required in connection with the Offer and the Merger and any repurchases or conversions of the Convertible Senior Notes occurring as a result of or in connection with the transactions contemplated by this Agreement constituting a "Fundamental Change" and/or "Make-Whole Fundamental Change" as such terms are defined in the respective Indentures, and the delivery of any supplemental indentures, legal opinions, officers' certificates or other documents or instruments required in connection with the Offer and the Merger and the consummation thereof.

(c) The Company shall deliver drafts of all notices, certificates, press releases, supplemental indentures, legal opinions, officers' certificates or other documents or instruments deliverable pursuant to or in connection with the Indentures or under applicable Law to Parent prior to the delivery, issuance or filing thereof by or on behalf of the Company, and shall cooperate in good faith with Parent to reflect any comments by Parent and to respond to any questions by Parent with respect thereto. The Company shall not amend, supplement , modify or waive the terms of the Indentures without the prior written consent of Parent.

5.14 Company Hedging Transactions and Warrants. The Company shall cooperate with Parent at Parent's request in connection with any discussions, negotiations or agreements with the counterparties to the Company Hedging Transactions or the Warrants, any of their respective affiliates or any other Person with respect to any determination or computation in connection with the Company Hedging Transactions or the Warrants, including, without limitation, with respect to any cash amounts or shares of Company Common Stock that may be receivable, issuable, deliverable or payable by the Company pursuant to the Company Hedging Transactions or the Warrants (including upon termination thereof). The Company shall not, and shall cause the Company Representatives not to, enter into any discussions, negotiations or agreements with respect to the foregoing without Parent's prior written consent, and shall keep Parent fully informed of all such discussions and negotiations and give Parent the option to participate in any such discussions and negotiations. Prior to the Effective Time, the Company shall take all such actions as may be required in accordance with, and subject to, the terms of the applicable letter agreements governing the Company Hedging Transactions and the Warrants, including the giving of any notices that may be required in connection with the Offer, the Merger and any conversions of the applicable Convertible Senior Notes or any adjustment to the respective Conversion Rate (as such term is defined in the applicable Indentures) occurring as a result of or in connection with the transactions contemplated by this Agreement.

8.6 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.

8.7 Severability. If any term or other provision (or part thereof) of this Agreement is invalid, illegal or incapable of being enforced by any rule of Law or public policy, all other conditions and provisions (or parts thereof) of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision (or part thereof) is invalid, illegal or incapable of being enforced, the Parties shall modify this Agreement, including restructuring the transactions contemplated hereby, so as to effect the original intent of the Parties as closely as possible (but in no event limiting the consideration to the Company's stockholders) in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

8.8 Entire Agreement. This Agreement (together with the Company Disclosure Schedule (which is an integral part of this Agreement and is incorporated herein by reference) and the other documents delivered pursuant hereto) and the Confidentiality Agreement constitute the entire agreement of the Parties and supersede all prior agreements and undertakings, both written and oral, among the Parties, or any of them, with respect to the subject matter of this Agreement and, except as otherwise expressly provided herein, are not intended to confer upon any other Person any rights or remedies hereunder.

8.9 Assignment. The Agreement shall not be assigned by any Party by operation of Law or otherwise without the prior written consent of the other Parties, provided that Merger Sub may assign any of its rights and obligations to Parent or any direct or indirect Subsidiary of Parent, but no such assignment shall relieve Merger Sub of its obligations hereunder.

8.10 No Third Party Beneficiaries.

(a) Subject to the following sentences in this Section 8.10, this Agreement shall be binding upon and inure solely to the benefit of each Party and their respective successors and assigns. Except (i) pursuant to Section 5.9, (ii) for the right of the Company on behalf of its stockholders to pursue damages (including, to the extent proven, damages based on loss of the economic benefit of the transactions contemplated by this Agreement to the Company's stockholders) and other relief (including equitable relief) in the event of Parent's or Merger Sub's breach of this Agreement (whether or not this Agreement has been terminated pursuant to Article VII), which right is hereby expressly acknowledged and agreed by Parent and Merger Sub, and (iii) with respect to the Financing Sources and their respective current, former or future directors, officers, general or limited partners, stockholders, members, managers, controlling persons, affiliates, employees or representatives who shall be third party beneficiaries of, and shall be entitled to rely on, Section 7.3, Section 8.12 and this Section 8.10 and shall have the right to consent to any modification of Section 7.3, Section 8.12 and this Section 8.10 to the extent such modification adversely affects their interests, nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement. The third party beneficiary rights referenced in clause (ii) of the preceding sentence may be exercised only by the Company (on behalf of its stockholders as their agent) through actions expressly approved by the Company Board, and no stockholder of the Company whether purporting to act in its capacity as a stockholder or purporting to assert any right (derivative or otherwise) on behalf of the Company, shall have any right or ability to exercise or cause the exercise of such right. The representations and warranties set forth in Articles III and IV and, except for Section 5.9, the covenants set forth in Article V have been made solely for the benefit of the Parties and (i) are intended not as statements of fact, but rather as a way of allocating the risk to one of the Parties if those statements prove to be inaccurate, (ii) have been qualified by reference to the Company Disclosure Schedule, which contains certain disclosures that are not reflected in the text of this Agreement and (iii) may apply standards of materiality in a way that is different from what may be viewed as material by stockholders of, or other investors in, the Company or Parent.

(b) Notwithstanding anything to the contrary contained herein, no Financing Source shall have any liability for any claims or damages to the Company or any of its affiliates, directors, officers, employees, agents and representatives in connection with this Agreement, the Financing, the Commitment Letter or the transactions contemplated hereby or thereby. The provisions of this Section 8.10(b) shall inure to the benefit of, and be enforceable by, each Financing Source and their respective successors and permitted assigns, each of which is hereby intended to be an express third party beneficiary of this Section 8.10(b).

8.11 Mutual Drafting; Interpretation. Each Party has participated in the drafting of this Agreement, which each Party acknowledges is the result of extensive

negotiations between the Parties. If an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties, and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any provision. For purposes of this Agreement, whenever the context requires: the singular number shall include the plural, and vice versa; the masculine gender shall include the feminine and neuter genders; the feminine gender shall include the masculine and neuter genders; and the neuter gender shall include the masculine and feminine genders. As used in this Agreement, the words "include" and "including," and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words "without limitation."

(b) Each of the Parties hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the Court of Chancery of the State of Delaware or, if under applicable Law, exclusive jurisdiction over such matters is vested in the Federal courts, any Federal court located in the State of Delaware, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the agreements delivered in connection herewith or the transactions contemplated hereby or thereby or for recognition or enforcement of any judgment relating thereto, and each of the Parties hereby irrevocably and unconditionally (i) agrees not to commence any such action or proceeding except in such courts, (ii) agrees that any claim in respect of any such action or proceeding may be heard and determined in such Court of Chancery or, to the extent required by Law, in such Federal court, (iii) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any such action or proceeding in any such court and (iv) waives, to the fullest extent permitted by Law, (x) any claim that such Party is not personally subject to the jurisdiction of any such court, (y) any claim that such Party and such Party's property is immune from any legal process issued by any such court and (z) the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. Each of the Parties agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Each Party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 8.3. Nothing in this Agreement will affect the right of any Party to serve process in any other manner permitted by Law.

limited partners, stockholders, members, managers, controlling persons, affiliates, employees or representatives in any way relating to this Agreement or any of the transactions contemplated by this Agreement, including any dispute arising out of or relating in any way to the Debt Financing or the Bond Financing or the performance thereof, in any forum other than any federal or state court located in the Borough of Manhattan in the City of New York.

(c) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT (INCLUDING ANY SUCH ACTION INVOLVING THE FINANCING SOURCES) IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

8.13 Counterparts. This Agreement may be executed in one or more counterparts, and by the different Parties in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by facsimile transmission or by e-mail of a .pdf attachment shall be effective as delivery of a manually executed counterpart of this Agreement.

8.14 Specific Performance. The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached or threatened to be breached. It is accordingly agreed that the Parties shall be entitled (without proof of actual damages or otherwise or posting or securing any bond) to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, these being in addition to any other remedy to which they are entitled at Law or in equity.

The Parties further agree not to assert that a remedy of specific performance is unenforceable, invalid, contrary to Law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide adequate remedy. Each of the Parties acknowledges and agrees that the right to specific performance and the other relief contemplated herein is an integral part of the transactions contemplated by this Agreement and without such right, none of the Parties would have entered into this Agreement.
