THE OFFER

2.1 The Offer.

(a) Terms and Conditions of the Offer. Provided that this Agreement shall not have been terminated pursuant to Article X, as promptly as practicable after the date hereof (but in no event more than ten (10) Business Days thereafter), Acquisition Sub shall (and Parent shall cause Acquisition Sub to) commence (within the meaning of Rule 14d-2 promulgated under the Exchange Act) the Offer to purchase any and all of the Company Shares at a price per Company Share, subject to Section 2.1(c), equal to the Offer Price. The Offer shall be made by means of an offer to purchase (the “Offer to Purchase”) that is disseminated to all of the Company Stockholders and contains the terms and conditions set forth in this Agreement and in Annex A. Each of Parent and Acquisition Sub shall use its reasonable best efforts to consummate the Offer, subject to the terms and conditions hereof and thereof. The Offer shall be subject only to:

(i) the condition (the “Minimum Condition”) that, prior to the expiration of the Offer, there be validly tendered (not including Company Shares tendered pursuant to procedures for guaranteed delivery) and not withdrawn in accordance with the terms of the Offer that number of Company Shares which, together with the number of Company Shares, if any, then owned beneficially by Parent, any wholly-owned subsidiary of Parent or Acquisition Sub, constitutes at least a majority of the total number of then outstanding Company Shares on a fully diluted basis (which shall mean, as of any time, the number of Company Shares outstanding, together with all Shares (if any) which the Company would be required to issue pursuant to any then outstanding warrants, options, restricted stock units, securities convertible or exchangeable into Shares or other binding obligations, but only to the extent then so exercisable, convertible or exchangeable or exercisable, convertible or exchangeable as a result of the consummation of the Offer); and

(ii) the other conditions set forth in Annex A.

(b) Acquisition Sub expressly reserves the right to waive any of the conditions to the Offer and to make any change in the terms of or conditions to the Offer; provided, however, that notwithstanding the foregoing or anything to the contrary set forth herein, without the prior written consent of the Company in its sole discretion, Acquisition Sub may not (and Parent shall not permit Acquisition Sub to) (i) waive the Minimum Condition, the condition set forth in clause (A) of Annex A or the condition set forth in clause (C)(1) of Annex A, and (ii) make any change in the terms of or conditions to the Offer that (A) changes the form of consideration to be paid in the Offer, (B) decreases the Offer Price or the number of Company Shares sought in the Offer, (C) extends the Offer, other than in a manner permitted or required by the provisions of Section 2.1(d)(ii), (D) imposes conditions to the Offer other than those set forth in Annex A, (E) modifies the conditions set forth in Annex A to make any of them more onerous, or (F) amends any other term of the Offer in any manner that is adverse to the holders of Shares.

(c) Adjustments to the Offer Price. The Offer Price shall be adjusted appropriately to reflect the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Company Common Stock), reclassification, combination, exchange of shares or other like change with respect to Company Common Stock occurring on or after the date hereof and prior to Acquisition Sub’s acceptance for payment of, and payment for, Company Shares that are tendered pursuant to the Offer.

(d) Expiration and Extension of the Offer.

(i) Unless the Offer is extended pursuant to and in accordance with this Agreement, the Offer shall expire at midnight, New York Time, on the date that is twenty (20) business days (for this purpose calculated in accordance with Section 14d-1(g)(3) promulgated under the Exchange Act) after the date the Offer is first commenced (within the meaning of Rule 14d-2 promulgated under the Exchange Act). In the event that the Offer is extended pursuant to and in accordance with this Agreement, then the Offer shall expire on the date and at the time to which the Offer has been so extended.

(ii) Notwithstanding the provisions of Section 2.1(d)(i) or anything to the contrary set forth in this Agreement:

(A) Acquisition Sub shall extend the Offer for any period required by any Law or Order, or any rule, regulation, interpretation or position of the SEC or its staff or Nasdaq, in any such case which is applicable to the Offer;

(B) in the event that any of the Antitrust Condition, the Illegality Condition or the Government Litigation Condition is not satisfied or waived (if permitted hereunder) as of any then scheduled expiration of the Offer (but, in the case of the Illegality Condition or the Government Litigation Condition, only to the extent that the failure of such condition to be satisfied or waived is as a result of a Law, Order or Legal Proceeding described therein relating to applicable Antitrust Laws), Acquisition Sub shall extend the Offer for successive extension periods of between one (1) and twenty (20) Business Days each in order to permit the satisfaction of the Antitrust Condition, the Illegality Condition or the Government Litigation Condition, as the case may be;

(C) in the event that any condition to the Offer (other than any such condition described in paragraph (B) above) is not satisfied or waived (if permitted hereunder) as of any then scheduled expiration of the Offer, Acquisition Sub may (at the sole discretion of Parent and Acquisition Sub) extend the Offer for successive extension periods of between one (1) and twenty (20) Business Days each in order to permit the satisfaction of all such conditions to the Offer; and

(D) in the event that the Company shall have delivered a Recommendation Change Notice pursuant to Section 6.3(b) or a Superior Proposal Notice

pursuant to Section 10.1(e), Acquisition Sub shall extend the Offer until 5:00 p.m. Pacific Time on the Business Day after the expiration of the three (3) Business Day period following such delivery of such Recommendation Change Notice or Superior Proposal Notice referenced in Section 6.3(b) and Section 10.1(e);

provided, however, that the foregoing clauses (A), (B), (C) or (D)of this Section 2.1(d)(ii) shall not be deemed to impair, limit or otherwise restrict in any manner the right of the parties to terminate this Agreement pursuant to the terms of Article X and provided, further, that Acquisition Sub shall not extend the Offer beyond the Termination Date without the consent of the Company.

(iii) Neither Parent nor Acquisition Sub shall extend the Offer in any manner other than pursuant to and in accordance with the provisions of Section 2.1(d)(ii) without the prior written consent of the Company.

(iv) Neither Parent nor Acquisition Sub shall terminate or withdraw the Offer prior to the then scheduled expiration of the Offer unless this Agreement is validly terminated in accordance with Article X, in which case Acquisition Sub shall (and Parent shall cause Acquisition Sub to) irrevocably and unconditionally terminate the Offer promptly (but in no event more than one Business Day) after such termination of this Agreement.

(e) Payment for Company Shares. On the terms and subject to conditions set forth in this Agreement and the Offer, Acquisition Sub shall (and Parent shall cause Acquisition Sub to) accept for payment, and pay for (or have paid for on its behalf by an Affiliate of Parent), all Company Shares that are validly tendered and not withdrawn pursuant to the Offer promptly (within the meaning of Section 14e-1(c) promulgated under the Exchange Act) after the expiration of the Offer. Without limiting the generality of the foregoing, Parent shall provide or cause to be provided to Acquisition Sub (or such Affiliate of Parent paying on Acquisition Sub’s behalf) on a timely basis the funds necessary to pay for any Company Shares that Acquisition Sub becomes obligated to purchase pursuant to the Offer. The Offer Price payable in respect of each Company Share validly tendered and not withdrawn pursuant to the Offer shall be paid net to the holder thereof in cash, without interest, subject to reduction for any applicable withholding taxes payable in respect thereof.

(f) Subsequent Offering Period. If upon the acceptance for payment of, and payment for, all Company Shares validly tendered and not withdrawn pursuant to the Offer, Parent and Acquisition Sub collectively do not beneficially own at least 90% of the Company Shares then outstanding, Acquisition Sub may (but shall not be required to), and the Offer to Purchase shall reserve the right to, provide for a “subsequent offering period” (within the meaning of Rule 14d-11 promulgated under the Exchange Act) of not less than three (3) nor more than twenty (20) Business Days immediately following the expiration of the Offer. Subject to the terms and conditions of this Agreement and the Offer, Acquisition Sub shall (and Parent shall cause Acquisition Sub to) accept for payment, and pay for (or have paid for on its behalf by an Affiliate of Parent), all Company Shares that are validly tendered during the “subsequent offering period” promptly (within the meaning of Section 14e-1(c) promulgated under the Exchange Act) after any such Company Shares are validly tendered during the “subsequent

offering period.” Without limiting the generality of the foregoing, Parent shall provide or cause to be provided to Acquisition Sub (or such Affiliate of Parent paying on Acquisition Sub’s behalf) on a timely basis the funds necessary to pay for any Company Shares that Acquisition Sub becomes obligated to purchase during such “subsequent offering period.” The Offer Price payable in respect of each Company Share that is validly tendered during the “subsequent offering period” shall be paid net to the holder thereof in cash, without interest, subject to reduction for any applicable withholding taxes payable in respect thereof.

(g) Schedule TO; Offer Documents. As soon as practicable on the date the Offer is first commenced (within the meaning of Rule 14d-2 promulgated under the Exchange Act), Parent and Acquisition Sub shall:

(i) prepare and file with the SEC a Tender Offer Statement on Schedule TO (together with all amendments and supplements thereto, and including all exhibits thereto, the “Schedule TO”) with respect to the Offer in accordance with Rule 14d-3(a) promulgated under the Exchange Act, which Schedule TO shall contain as an exhibit the Offer to Purchase and forms of the letter of transmittal and summary advertisement, if any, and other customary ancillary documents, in each case, in respect of the Offer (together with any supplements or amendments thereto, the “Offer Documents”);

(ii) deliver a copy of the Schedule TO, including all exhibits thereto, to the Company at its principal executive offices in accordance with Rule 14d-3(a) promulgated under the Exchange Act;

(iii) give telephonic notice of the information required by Rule 14d-3 promulgated under the Exchange Act, and mail by means of first class mail a copy of the Schedule TO, to Nasdaq in accordance with Rule 14d-3(a) promulgated under the Exchange Act; and

Subject to the provisions of Section 6.3, the Schedule TO and the Offer Documents may include a description of the determinations, approvals and recommendations of the Company Board set forth in Section 2.2(a) and Section 6.3(a) that relate to the Offer. The Company shall furnish in writing to Parent and Acquisition Sub all information concerning the Company and its Subsidiaries that is reasonably determined by Parent to be required by applicable Law and reasonably requested by Parent to be included in the Schedule TO or the Offer Documents so as to enable Parent and Acquisition Sub to comply with their obligations under this Section 2.1(g). Parent, Acquisition Sub and the Company shall cooperate in good faith to determine the information regarding the Company that is necessary or reasonably appropriate to include in the Schedule TO and the Offer Documents in order to satisfy applicable Laws. Each of Parent, Acquisition Sub and the Company shall promptly correct any information provided by it or any of its respective directors, officers, employees, affiliates, agents or other representatives for use in the Schedule TO or the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect. Parent and Acquisition Sub shall take all

steps necessary to cause the Schedule TO and the Offer Documents, as so corrected, to be filed with the SEC and the other Offer Documents, as so corrected, to be disseminated to the Company Stockholders, in each case as and to the extent required by applicable Laws, or by the SEC or its staff. Parent and Acquisition Sub shall provide the Company and its counsel a reasonable opportunity to review and comment on the Schedule TO and the Offer Documents prior to the filing thereof with the SEC, and Parent and Acquisition Sub shall give reasonable and good faith consideration to any comments made by the Company and its counsel (it being understood that the Company and its counsel shall provide any comments thereon as soon as reasonably practicable).

2.2 Company Actions.

The Company hereby consents to the inclusion of the foregoing determinations and approvals in the Offer Documents and, to the extent that the foregoing recommendation of the Company Board is not withheld, withdrawn, amended or modified in accordance with Section 6.3, the Company hereby consents to the inclusion of such recommendation in the Offer Documents. To the knowledge of the Company, as of the date of this Agreement, all of the Company’s directors and executive officers intend to tender all Shares beneficially owned by them to Acquisition Sub pursuant to the Offer, except as otherwise set forth in Section 2.2 of the Company Disclosure Letter.

(b) Schedule 14D-9. The Company shall (i) file with the SEC, concurrently with the filing by Parent and Acquisition Sub of the Schedule TO, a Solicitation/Recommendation Statement on Schedule 14D-9 (together with all amendments and supplements thereto, and including all exhibits thereto, the “Schedule 14D-9”) and (ii) cause the Schedule 14D-9 to be mailed to the Company Stockholders, to the extent reasonably practical together with the Offer Documents, promptly after the commencement of the Offer (within the meaning of Rule 14d-2 promulgated under the Exchange Act). Subject to the provisions of Section 6.3, the Schedule 14D-9 shall include a description of the determinations, approvals and recommendations of the Company Board (including the Company Board Recommendation) set forth in Section 2.2(a) and Section 6.3(a). Each of Parent and Acquisition Sub shall furnish in writing to the Company all information concerning Parent and Acquisition Sub that is reasonably determined by the Company to be required by applicable Law and reasonably requested by the Company to be included in the Schedule 14D-9 so as to enable the Company to comply with its obligations under this Section 2.2(b).

The Company shall take all steps necessary to cause the Schedule 14D-9, as so corrected, to be filed with the SEC and disseminated to the Company Stockholders, in each case as and to the extent required by applicable Laws. Unless the Company Board has effected a Company Board Recommendation Change, the Company shall provide Parent, Acquisition Sub and their counsel a reasonable opportunity to review and comment on the Schedule 14D-9 prior to the filing thereof with the SEC, and the Company shall give reasonable and good faith consideration to any comments made by Parent, Acquisition Sub and their counsel (it being understood that Parent, Acquisition Sub and their counsel shall provide any comments thereon as soon as reasonably practicable).

2.3 Company Board of Directors and Committees; Section 14(f) of Exchange Act.

(a) Composition of Company Board and Board Committees. Effective upon the initial acceptance for payment by Acquisition Sub of Company Shares pursuant to the Offer (the “Appointment Time,” the use of which term herein shall not, unless the context otherwise requires, depend upon whether Parent shall exercise its rights under this Section 2.3(a)) and from time to time thereafter, Parent shall be entitled to designate up to such number of directors on the Company Board equal to the product (rounded up to the next whole number) obtained by multiplying (x) the number of directors on the Company Board (giving effect to any increase in the number of directors pursuant to this Section 2.3) and (y) a fraction, the numerator of which is the number of Company Shares beneficially owned by Parent and Acquisition Sub (giving effect to the Company Shares accepted for payment pursuant to the Offer), and the denominator of which is the total number of then outstanding Company Shares. Following a request by Parent, the Company shall, to the extent permitted by applicable Laws and the certificate of incorporation of the Company, take all action necessary to cause the individuals so designated by Parent to be elected or appointed to the Company Board, including (at the direction of Parent) by increasing the size of the Company Board or by seeking and accepting or otherwise securing the resignations of such number of then incumbent directors as is necessary to enable the individuals

so designated by Parent to be elected or appointed to the Company Board. From time to time after the Appointment Time, at the request of Parent, the Company shall, to the extent permitted by applicable Laws and the certificate of incorporation of the Company, take all action necessary to cause the individuals so designated by Parent to constitute substantially the same percentage (rounding up where appropriate) as is on the Company Board on (i) each committee of the Company Board, (ii) each board of directors of each Subsidiary of the Company and (iii) each committee of each such board of directors of each Subsidiary of the Company, in each case to the fullest extent permitted by all applicable Laws. The Company shall promptly amend, or cause to be amended, its bylaws, if necessary to comply with the obligations of the Company pursuant to this Section 2.3. Notwithstanding the foregoing, from the Appointment Time until the Effective Time, the Company shall use its commercially reasonable efforts to cause the Company Board to always include at least such number of directors who are directors on the date hereof, who are not employed by the Company, who are not Affiliates or employees of Parent or any of its Subsidiaries, and who are independent directors in order to satisfy the continued listing requirements of Nasdaq (the “Continuing Directors”); provided that, if the number of Continuing Directors shall be reduced below those necessary to satisfy the continued listing requirements of Nasdaq, for any reason whatsoever, the remaining Continuing Director shall be entitled to designate any other Person(s) who shall not be an Affiliate or employee of Parent or any of its Subsidiaries to fill such vacancies and such Person(s) shall be deemed to be a Continuing Director(s) for purposes of this Agreement; provided further, that the remaining Continuing Director shall fill such vacancies as soon as practicable, but in any event within ten (10) Business Days, and further provided that if no such Continuing Director is appointed in such time period, Parent shall designate such Continuing Director; provided further, that if no Continuing Director then remains, the other directors shall designate two (2) Persons who shall not be Affiliates, consultants, representatives or employees of Parent or any of its Subsidiaries to fill such vacancies and such Persons shall be deemed to be Continuing Directors for purposes of this Agreement.

(b) Section 14(f) of the Exchange Act. The Company’s obligation to appoint Parent’s designees to the Company Board shall be subject to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder and the Company’s receipt of sufficient information from Parent to enable the Company to include in the Schedule 14D-9 the information required by Section 14(f) of the Exchange Act and Rule and Rule 14f-1 promulgated thereunder in respect of Parent’s designees to the Company Board. The Company shall take all action required pursuant to this Section 2.3 and Section 14(f) and Rule 14f-1 in order to fulfill its obligations under this Section 2.3, and shall include in the Schedule 14D-9 such information with respect to the Company and its directors and officers, as well as Parent’s designees to the Company Board, as is required under such Section 14(f) and Rule 14f-1 in order to fulfill its obligations under this Section 2.3. Parent shall provide to the Company in writing, and be solely responsible for, any information with respect to itself and its designees to the Company Board required by such Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder.

(c) Required Approvals of Continuing Directors. Notwithstanding anything in this Agreement to the contrary, following the election or appointment of Parent’s designees to the Company Board pursuant to Section 2.3(a) and until the Effective Time, the approval of a majority of the Continuing Directors shall be required to authorize (and such authorization shall

constitute the authorization of the Company Board and no other action on the part of the Company, including any action by any other director of the Company, shall be required to authorize) (i) any amendment or termination of this Agreement on behalf of the Company, (ii) any amendment of this Agreement requiring action by the Company Board, (iii) any extension of time for performance of any obligation or action hereunder by Parent or Acquisition Sub, (iv) any exercise, enforcement or waiver of compliance with any of the agreements or conditions contained herein for the benefit of the Company and (v) any amendment of the certificate of incorporation or bylaws of the Company that would adversely affect the Company Stockholders; provided however, that following the Appointment Time, Parent may cause its designees elected or appointed pursuant to Section 2.3(a) to withdraw or modify any Company Board Recommendation Change. The Continuing Directors shall have the authority to retain counsel (which may include current counsel to the Company) at the expense of the Company for the purpose of fulfilling their obligations hereunder, and shall have the authority, after the Appointment Time but prior to the Effective Time, to institute any action on behalf of the Company to enforce the performance of this Agreement in accordance with its terms.

2.4 Top-Up Option.

(a) The Company hereby irrevocably grants to Acquisition Sub an option (the “Top-Up Option”), exercisable only upon the terms and conditions set forth in this Section 2.4, to purchase that number of authorized and unissued Company Shares (the “Top-Up Option Shares”) equal to the lowest number of Company Shares that, when added to the number of Company Shares beneficially owned by Parent and/or Acquisition Sub at the time of such exercise, shall constitute 100 Company Shares more than 90% of the Company Shares then outstanding on a fully diluted basis (assuming the issuance of the Top-Up Option Shares) at a price per share equal to the Offer Price; provided, however, that the Top-Up Option shall not be exercisable unless immediately after such exercise and the issuance of Company Shares pursuant thereto, Parent, Acquisition Sub or any of Parent’s other wholly-owned Subsidiaries would own more than 90% of the Company Shares then outstanding (assuming the issuance of the Top-Up Option Shares); and provided further, that in no event shall the Top-Up Option be exercisable (A) for a number of Company Shares in excess of the Company’s then authorized and unissued shares of Company Common Stock or (B) if any applicable Law (which for the avoidance of doubt shall not include the rules of Nasdaq) or any applicable Order shall prohibit the exercise of the Top-Up Option or the delivery of the Top-Up Option Shares.

(b) Provided that no applicable Law (which for the avoidance of doubt shall not include the rules of Nasdaq) or Order shall prohibit the exercise of the Top-Up Option or the delivery of the Top-Up Option Shares in respect thereof, Acquisition Sub may exercise the Top-Up Option, in whole but not in part, at any one time after the Appointment Time and prior to the earlier to occur of (i) the Effective Time and (ii) the termination of this Agreement in accordance with its terms. The aggregate purchase price payable for the Top-Up Option Shares being purchased by Acquisition Sub pursuant to the Top-Up Option shall be determined by multiplying the number of such Top-Up Option Shares by the Offer Price, without interest. Such purchase price may be paid by Acquisition Sub, at its election, either (A) entirely in cash or (B) in cash in an amount equal to the aggregate par value of the purchased Top-Up Option Shares and by executing and delivering to the Company a full recourse promissory note having a principal

amount equal to the remainder of such purchase price. Any such promissory note shall bear interest at a rate per annum equal to the prime lending rate prevailing during the period in which any portion of the principal amount of such promissory note remains outstanding, as published in The Wall Street Journal, calculated on a daily basis on the outstanding principal amount of such promissory note from the date such promissory note is originally issued until the date of payment in full of such promissory note, and may be prepaid without premium or penalty. The unpaid principal amount and accrued interest under the promissory note shall immediately become due and payable in the event that (x) Acquisition Sub fails to make any payment of interest on the promissory note as provided therein and such failure continues for a period of 30 days or (y) Acquisition Sub files any petition under any bankruptcy or insolvency law or makes a general assignment for the benefit of creditors.

(c) In the event Acquisition Sub wishes to exercise the Top-Up Option, Acquisition Sub shall deliver to the Company a notice (the “Top-Up Notice”) setting forth (i) the number of Top-Up Option Shares that Acquisition Sub intends to purchase pursuant to the Top-Up Option, (ii) the manner in which Acquisition Sub intends to pay the applicable purchase price and (iii) the place and time at which the closing of the purchase of such Top-Up Option Shares by Acquisition Sub is to take place. At the closing of the purchase of the Top-Up Option Shares, Parent and Acquisition Sub shall cause to be delivered to the Company the consideration required to be delivered in exchange for the Top-Up Option Shares being purchased pursuant to the Top-Up Option, and the Company shall cause to be issued to Acquisition Sub a certificate representing such Top-Up Option Shares. The parties hereto agree to use their reasonable best efforts to cause the closing of the purchase of such Top-Up Option Shares to occur on the same day that the Top-Up Notice is deemed received by the Company pursuant to Section 11.2, and if not so consummated on such day, as promptly thereafter as possible. The parties further agree to use their reasonable best efforts to cause the Merger to be consummated in accordance with Section 253 of the DGCL and as contemplated by Section 8.3(c) as close in time as possible to (including, to the extent possible, on the same day as) the issuance of the Top-Up Option Shares.

(d) Parent and Acquisition Sub understand that the Company Shares which Acquisition Sub may acquire upon exercise of the Top-Up Option will not be registered under the Securities Act and will be issued in reliance upon an exemption thereunder for transactions not involving a public offering. Parent and Acquisition Sub represent and warrant to the Company that Acquisition Sub is, or will be upon the purchase of the Top-Up Option Shares, an “accredited investor,” as defined in Rule 501 of Regulation D promulgated under the Securities Act. Acquisition Sub agrees that the Top-Up Option and the Top-Up Option Shares to be acquired upon exercise of the Top-Up Option are being and will be acquired by Acquisition Sub for the purpose of investment and not with a view to or for resale in connection with any distribution thereof within the meaning of the Securities Act. Any certificates evidencing Top-Up Option Shares shall include any legends required by applicable securities Laws.

The date upon which the Closing shall actually occur pursuant hereto is referred to herein as the “Closing Date.”

3.4 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in this Agreement and the applicable provisions of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time all of the property, rights, privileges, powers and franchises of the Company and Acquisition Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Acquisition Sub shall become the debts, liabilities and duties of the Surviving Corporation.

3.5 Certificate of Incorporation and Bylaws.

(a) Certificate of Incorporation. At the Effective Time, subject to the provisions of Section 7.1(a), the certificate of incorporation of the Company shall be amended and restated in its entirety to read identically to the certificate of incorporation of Acquisition Sub, as in effect immediately prior to the Effective Time, and such amended and restated certificate of incorporation shall become the certificate of incorporation of the Surviving Corporation until thereafter amended in accordance with the applicable provisions of the DGCL

and such certificate of incorporation; provided, however, that at the Effective Time the certificate of incorporation of the Surviving Corporation shall be amended so that the name of the Surviving Corporation shall be “Isilon Systems, Inc.”

(b) Bylaws. At the Effective Time, subject to the provisions of Section 7.1(a), the bylaws of Acquisition Sub, as in effect immediately prior to the Effective Time, except as to the name of the Surviving Corporation, which shall be “Isilon Systems, Inc.”, shall become the bylaws of the Surviving Corporation until thereafter amended in accordance with the applicable provisions of the DGCL, the certificate of incorporation of the Surviving Corporation and such bylaws.

3.6 Directors and Officers.

(a) Directors. At the Effective Time, the initial directors of the Surviving Corporation shall be the directors of Acquisition Sub immediately prior to the Effective Time, each to hold office in accordance with the certificate of incorporation and bylaws of the Surviving Corporation until their respective successors are duly elected or appointed and qualified.

(b) Officers. At the Effective Time, the initial officers of the Surviving Corporation, unless otherwise requested in writing by Parent, shall be the officers of the Company immediately prior to the Effective Time, each to hold office in accordance with the certificate of incorporation and bylaws of the Surviving Corporation until their respective successors are duly appointed.

3.7 Effect on Capital Stock.

(a) Capital Stock. Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of Parent, Acquisition Sub, the Company, or the holders of any of the following securities, the following shall occur:

(i) Capital Stock of Acquisition Sub. Each share of common stock, par value $0.01 per share, of Acquisition Sub that is outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation. Each certificate evidencing ownership of such shares of common stock of Acquisition Sub shall thereafter evidence ownership of shares of common stock of the Surviving Corporation.

(ii) Company Common Stock. Each share of Company Common Stock that is outstanding immediately prior to the Effective Time (other than (A) shares of Company Common Stock owned by Parent, Acquisition Sub or the Company, or by any direct or indirect wholly-owned Subsidiary of Parent, Acquisition Sub or the Company, in each case immediately prior to the Effective Time, and (B) any Dissenting Company Shares) shall be canceled and extinguished and automatically converted into the right to receive cash in an amount equal to the Offer Price (the “Merger Consideration”), without interest thereon, upon

the surrender of the certificate representing such share of Company Common Stock in the manner provided in Section 3.8 (or in the case of a lost, stolen or destroyed certificate, upon delivery of an affidavit in the manner provided in Section 3.10).

(iii) Owned Company Common Stock. Each share of Company Common Stock owned by Parent, Acquisition Sub or the Company, or by any direct or indirect wholly-owned Subsidiary of Parent, Acquisition Sub or the Company, in each case immediately prior to the Effective Time, shall be cancelled and extinguished without any conversion thereof or consideration paid therefor.

(b) Adjustment to the Merger Consideration. The Merger Consideration shall be adjusted appropriately to reflect the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Company Common Stock), reclassification, combination, exchange of shares or other like change with respect to Company Common Stock occurring on or after the consummation of the Offer and prior to the Effective Time.

(i) Notwithstanding anything to the contrary set forth in this Agreement, all shares of Company Common Stock that are issued and outstanding immediately prior to the Effective Time and held by Company Stockholders who shall have neither voted in favor of the Merger nor consented thereto in writing and who shall have properly and validly perfected their statutory rights of appraisal in respect of such shares of Company Common Stock in accordance with Section 262 of the DGCL (collectively, “Dissenting Company Shares”) shall not be converted into, or represent the right to receive, the Merger Consideration pursuant to Section 3.7(a). Such Company Stockholders shall be entitled to receive payment of the appraised value of such Dissenting Company Shares in accordance with the provisions of Section 262 of the DGCL, except that all Dissenting Company Shares held by Company Stockholders who shall have failed to perfect or who shall have effectively withdrawn or lost their rights to appraisal of such Dissenting Company Shares under such Section 262 of the DGCL shall no longer be considered to be Dissenting Company Shares and shall thereupon be deemed to have been converted into, and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration, without interest thereon, upon surrender of the certificate or certificates that formerly evidenced such shares of Company Common Stock in the manner provided in Section 3.8.

(ii) The Company shall give Parent (A) prompt notice of any demands for appraisal received by the Company, withdrawals of such demands, and any other instruments served pursuant to Delaware Law and received by the Company in respect of Dissenting Company Shares and (B) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under Delaware Law in respect of Dissenting Company Shares. The Company shall not, except with the prior written consent of Parent, voluntarily make any payment with respect to any demands for appraisal, or settle or offer to settle any such demands for payment, in respect of Dissenting Company Shares. The parties agree and acknowledge that in any appraisal proceeding with respect to the Dissenting Company Shares and to the fullest

extent permitted by applicable Law, the fair value of the Dissenting Company Shares shall be determined in accordance with Section 262(h) of the DGCL without regard to the Top-Up Option, the Top-Up Option Shares or any consideration paid or delivered by Parent or Acquisition Sub to the Company in payment for the Top-Up Option Shares.

(d) Company RSUs. Parent shall not assume any Company RSUs in connection with the Merger or any other transactions contemplated by this Agreement. Upon the terms and subject to the conditions set forth in this Agreement, except as otherwise agreed to by Parent and a holder of a Company RSU, the Company shall take all such action as may be necessary so that immediately prior to the Effective Time, (i) each Company RSU that remains outstanding as of immediately prior to the Effective Time (whether or not vested) shall be cancelled and terminated as of the Effective Time, and (ii) each holder of each such Company RSU shall be paid by the Company at or promptly after the Effective Time, subject to Section 3.8(e), an amount in cash (without interest) equal to the product obtained by multiplying (x) the aggregate number of shares or fractional shares of Company Common Stock represented by such Company RSU (assuming full vesting of such Company RSU), by (y) the Offer Price. The Company shall take all actions necessary to effect the transactions contemplated by this Section 3.7(d) under all Company Stock Plans and any other plan or arrangement of the Company, including delivering all notices and making any determinations and/or resolutions of the Company Board or a committee thereof.

(e) Company Options.

(i) Parent shall not assume any Vested Company Options in connection with the Merger or any other transactions contemplated by this Agreement. Upon the terms and subject to the conditions set forth in this Agreement, the Company shall take such action as may be necessary so that immediately prior to the Effective Time, (i) each Vested Company Option that remains outstanding as of immediately prior to the Effective Time shall be cancelled and terminated as of the Effective Time, and (ii) in consideration of such cancellation and termination, each holder of each such Vested Company Option shall be paid by the Company promptly following the Effective Time, subject to Section 3.8(e), an amount in cash (without interest), if any, equal to the product obtained by multiplying (x) the aggregate number of shares of Company Common Stock that were issuable upon exercise of such Vested Company Option immediately prior to the Effective Time, and (y) the Offer Price, less the per share exercise price of such Vested Company Option.

(ii) In connection with the transactions contemplated by this Agreement, at the Effective Time each Unvested Company Option shall be assumed by Parent (each, an “Assumed Option”). Each such Assumed Option shall be subject to the same terms and conditions as applied to the related Unvested Company Option immediately prior to the Effective Time, including the vesting schedule applicable thereto, except that (i) the number of shares of Parent Common Stock subject to each Assumed Option shall be determined by multiplying the number of shares of Company Common Stock subject to such Assumed Option as of immediately prior to the Effective Time by the Option Exchange Ratio (with the resulting number rounded down to the nearest whole share), and (ii) the per share exercise price of the Parent Common Stock issuable upon the exercise of each Assumed Option shall be equal to the

quotient determined by dividing the exercise price per share of Company Common Stock as of immediately prior to the Effective Time by the Option Exchange Ratio, with the resulting price per share rounded up to the nearest whole cent. It is the intention of the parties that each Assumed Option so assumed by Parent shall qualify following the Effective Time as an incentive stock option as defined in Section 422 of the Code to the extent permitted under Section 422 of the Code and to the extent such Assumed Option qualifies as an incentive stock option prior to the Effective Time and, further, that the assumption of Unvested Company Options pursuant to this Section shall be effected in a manner that satisfies the requirements of Sections 409A and 424(a) of the Code and the Treasury Regulations promulgated thereunder, and this Section 3.7(e) will be construed consistent with this intent.

(iii) With respect to Company Options a portion of which is vested and a portion of which is unvested, this Section 3.7(e) shall be applied by treating the vested portion as a separate Vested Company Option and the unvested portion as a separate Unvested Company Option.

(iv) The Company shall take all actions necessary to effect the transactions contemplated by this Section 3.7(e) under all Company Option agreements and any other plan or arrangement of the Company, including delivering all required notices and making any determinations and/or resolutions of the Company Board or a committee thereof. Parent shall take all actions reasonably necessary or appropriate to have available for issuance or transfer a sufficient number of shares of Parent Common Stock for delivery upon exercise of the Assumed Options. As promptly as practicable after the Effective Time, Parent shall prepare and file with the SEC a registration statement on Form S-8, to the extent such form is available, registering a number of shares of Parent Common Stock necessary to fulfill Parent’s obligations under this Section 3.7(e) .

(f) Company ESPP.

(i) Prior to the Appointment Time, the Company shall take all actions necessary to cause the rights of participants in the Company ESPP with respect to any offering period then underway to be determined by treating the last Business Day prior to, or if more administratively advisable, the last payroll date of the Company immediately prior to, the Appointment Time, as the last day of such offering period and by making such other pro-rata adjustments as may be necessary to reflect the shortened and final offering period but otherwise treating such shortened and final offering period as a fully effective and completed offering period for all purposes under the Company ESPP.

(ii) The Company shall take all actions necessary so that the Company ESPP shall terminate immediately following the Appointment Time. All amounts withheld by the Company on behalf of the participants in the Company ESPP that have not been used to purchase Company Common Stock prior to the Effective Time will be returned to the participants without interest pursuant to the terms of the Company ESPP.

(iii) The Company agrees to take any and all actions necessary to approve and effectuate the foregoing provisions of this Section 3.7(f) including making any determinations and/or resolutions of the Company Board or a committee thereof.

3.8 Exchange of Certificates.

(a) Payment Agent. Prior to the Effective Time, Parent shall select a bank or trust company reasonably acceptable to the Company to act as the payment agent for the Merger (the “Payment Agent”).

(b) Exchange Fund. At the Closing, Parent shall deposit (or cause to be deposited) with the Payment Agent, for payment to the holders of shares of Company Common Stock pursuant to the provisions of this Article III, an amount of cash equal to the aggregate consideration to which holders of Company Common Stock become entitled under this Article III. Until disbursed in accordance with the terms and conditions of this Agreement, such funds shall be invested by the Payment Agent, as directed by Parent or the Surviving Corporation (such cash amount being referred to herein as the “Exchange Fund”). Any interest and other income resulting from such investments shall be paid to Parent. To the extent that there are any losses with respect to any investments of the Exchange Fund, or the Exchange Fund diminishes for any reason below the level required for the Payment Agent to promptly pay the cash amounts contemplated by this Article III, Parent shall, or shall cause the Surviving Corporation to, promptly replace or restore the cash in the Exchange Fund so as to ensure that the Exchange Fund is at all times maintained at a level sufficient for the Payment Agent to make such payments contemplated by this Article III.

(c) Payment Procedures. Promptly following the Effective Time, Parent and the Surviving Corporation shall cause the Payment Agent to mail to each holder of record (as of immediately prior to the Effective Time) of (i) a certificate or certificates (the “Certificates”) which immediately prior to the Effective Time represented outstanding shares of Company Common Stock (other than Dissenting Company Shares) and (ii) uncertificated shares of Company Common Stock (the “Uncertificated Shares”), in each case, whose shares were converted into the right to receive the Merger Consideration pursuant to Section 3.7 (A) a letter of transmittal in customary form (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 Payment Agent), and/or (B) instructions for use in effecting the surrender of the Certificates and Uncertificated Shares in exchange for the Merger Consideration payable in respect thereof pursuant to the provisions of this Article III. Upon surrender of Certificates for cancellation to the Payment Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the holders of such Certificates shall be entitled to receive in exchange therefor an amount in cash equal to the product obtained by multiplying (x) the aggregate number of shares of Company Common Stock represented by such Certificate that were converted into the right to receive the Merger Consideration pursuant to Section 3.7, by (y) the Merger Consideration (less any applicable withholding taxes payable in respect thereof), and the Certificates so surrendered shall forthwith be canceled. Upon receipt of an “agent’s message” by the Payment Agent (or such other evidence, if any, of transfer as the Payment Agent may

reasonably request) in the case of a book-entry transfer of Uncertificated Shares, the holders of such Uncertificated Shares shall be entitled to receive in exchange therefor an amount in cash equal to the product obtained by multiplying (x) the aggregate number of shares of Company Common Stock represented by such holder’s transferred Uncertificated Shares that were converted into the right to receive the Merger Consideration pursuant to Section 3.7, by (y) the Merger Consideration (less any applicable withholding taxes payable in respect thereof), and the transferred Uncertificated Shares so surrendered shall forthwith be canceled. The Payment Agent shall accept such Certificates and transferred Uncertificated Shares upon compliance with such reasonable terms and conditions as the Payment Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices. No interest shall be paid or accrued for the benefit of holders of the Certificates and Uncertificated Shares on the Merger Consideration payable upon the surrender of such Certificates and Uncertificated Shares pursuant to this Section 3.8. Until so surrendered, outstanding Certificates and Uncertificated Shares shall be deemed from and after the Effective Time, to evidence only the right to receive the Merger Consideration, without interest thereon, payable in respect thereof pursuant to the provisions of this Article III.

(d) Transfers of Ownership. In the event that a transfer of ownership of shares of Company Common Stock is not registered in the stock transfer books or ledger of the Company, or if the Merger Consideration is to be paid in a name other than that in which the Certificates or Uncertificated Shares surrendered in exchange therefor are registered in the stock transfer books or ledger of the Company, the Merger Consideration may be paid to a Person other than the Person in whose name the Certificate or Uncertificated Share so surrendered is registered in the stock transfer books or ledger of the Company only if such Certificate or Uncertificated Shares is properly endorsed and otherwise in proper form for surrender and transfer and the Person requesting such payment has paid any transfer and other similar Taxes required to be paid by reason of the payment of the Merger Consideration to a Person other than the registered holder of such Certificate or Uncertificated Shares, or established to the satisfaction of Parent (or any agent designated by Parent) that such transfer and other similar Taxes have been paid or are otherwise not payable.

(e) Required Withholding. Each of the Payment Agent, Parent, Acquisition Sub, the Company and the Surviving Corporation, and any agent of any of the foregoing, shall be entitled to deduct or withhold from any cash amounts payable pursuant to this Agreement such amounts as may be required to be deducted or withheld therefrom under United States federal, state, local or foreign Tax Laws. To the extent that such amounts are so deducted or withheld (and remitted, to the extent required by applicable Law, to the applicable Governmental Authority) such amounts shall be treated for all purposes of this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

(f) No Liability. Notwithstanding anything to the contrary set forth in this Agreement, none of the Payment Agent, Parent, the Surviving Corporation or any other party hereto shall be liable to a holder of shares of Company Common Stock for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(g) Distribution of Exchange Fund to Parent. Any portion of the Exchange Fund that remains undistributed to the holders of the Certificates or Uncertificated Shares on the date that is six (6) months after the Effective Time shall be delivered to Parent upon demand, and any holders of shares of Company Common Stock that were issued and outstanding immediately prior to the Merger who have not theretofore surrendered their Certificates or Uncertificated Shares representing such shares of Company Common Stock for exchange pursuant to the provisions of this Section 3.8 shall thereafter look for payment of the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Certificates or Uncertificated Shares solely to Parent, as general creditors thereof, for any claim to the applicable Merger Consideration to which such holders may be entitled pursuant to the provisions of this Article III.

3.9 No Further Ownership Rights in Company Common Stock. From and after the Effective Time, all shares of Company Common Stock (other than Dissenting Company Shares) shall no longer be outstanding and shall automatically be cancelled, retired and cease to exist, and each holder of a Certificate or Uncertificated Shares theretofore representing any shares of Company Common Stock shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration payable therefor upon the surrender thereof in accordance with the provisions of Section 3.8. The Merger Consideration paid in accordance with the terms of this Article III shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of the Company Common Stock. From and after the Effective Time, there shall be no further registration of transfers on the records of the Surviving Corporation of shares of Company Common Stock that were issued and outstanding immediately prior to the Effective Time, other than transfers to reflect, in accordance with customary settlement procedures, trades effected prior to the Effective Time. If, after the Effective Time, Certificates or Uncertificated Shares are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article III.

3.10 Lost, Stolen or Destroyed Certificates. In the event that any Certificates shall have been lost, stolen or destroyed, the Payment 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 3.7.

3.11 Necessary Further Actions. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of the Company and Acquisition Sub, the directors and officers of the Company and Acquisition Sub shall take all such lawful and necessary action.

4.5 Required Governmental Approvals. No consent, approval, Order or authorization of, or filing or registration with, or notification to (any of the foregoing being referred to herein as a “Consent”), any Governmental Authority is required on the part of the Company in connection with the execution and delivery by the Company of this Agreement, the performance by the Company of its covenants and obligations hereunder and the consummation by the Company of the transactions contemplated hereby, except (a) the filing and recordation of the Certificate of Merger with the Delaware Secretary of State and such filings with Governmental Authorities to satisfy the applicable laws of states in which the Company and its Subsidiaries are qualified to do business, (b) such filings and approvals as may be required by any federal or state securities laws, including compliance with any applicable requirements of the Exchange Act, (c) Consents required under, and compliance with any other applicable requirements of the HSR Act and any applicable foreign Antitrust Laws, and (d) such other Consents, the failure of which to obtain would not have, individually or in the aggregate, a Company Material Adverse Effect or prevent or materially delay the consummation by the Company of the transactions contemplated hereby or the ability of the Company to perform its covenants and obligations hereunder.

(c) Notwithstanding anything to the contrary set forth in this Section 6.2 or elsewhere in this Agreement, prior to the Appointment Time, the Company Board may, directly or indirectly through the Company’s Representatives, (i) participate or engage in discussions or negotiations with any Person that has made a bona fide, written and unsolicited Acquisition Proposal that the Company Board determines in good faith (after consultation with its financial advisors and outside legal counsel) either constitutes or is reasonably expected to lead to a Superior Proposal (ii) furnish to any such Person non-public information relating to the Company

and access to the business, properties, assets, books, records or other non-public information, or to any personnel, of the Company or any of its Subsidiaries, in each case under this clause (ii) pursuant to a confidentiality agreement with terms, including “stand-still” provisions (the “standstill” provisions of which do not include a “sunset”, “fall-away” or other similar exception that would result in the “standstill” provisions becoming inapplicable at any time prior to the valid termination of this Agreement in accordance with its terms), the terms of which are no less favorable to the Company than those contained in the Confidentiality Agreement; provided, however, that in the case of any action taken pursuant to the preceding clauses (i) or (ii), (A) the Company Board determines in good faith (after consultation with outside legal counsel) that the failure to take such action would reasonably be expected to result in a breach of its fiduciary duties to the Company Stockholders under Delaware Law, (B) the Company gives Parent not less than 24 hours prior written notice of the identity of such Person and the material terms of such Acquisition Proposal (unless such Acquisition Proposal is in written form, in which case the Company shall give Parent a copy thereof) and of the Company’s intention to participate or engage in discussions or negotiations with, or furnish non-public information to, such Person, (C) contemporaneously with furnishing any non-public information to such Person, the Company furnishes such non-public information to Parent to the extent such information has not been previously furnished by the Company to Parent and (D) there has not been any material breach of this Section 6.2 by the Company (including any such material breach deemed to have occurred pursuant to Section 6.2(d)).

(d) Without limiting the generality of the foregoing, Parent, Acquisition Sub and the Company acknowledge and hereby agree that any violation of the restrictions set forth in this Section 6.2 by any directors or officers or outside Representatives of the Company or its Subsidiaries shall be deemed to be a breach of this Section 6.2 by the Company.

(e) In addition to the obligations of the Company set forth in Section 6.2(b), the Company shall promptly (and in any event within 24 hours following receipt) notify Parent orally and in writing if the Company or any of its Subsidiaries or any of its or its Subsidiaries’ Representatives receives (i) any Acquisition Proposal, (ii) any request for information that would reasonably be expected to lead to an Acquisition Proposal, or (iii) any inquiry with respect to, or which would reasonably be expected to lead to, any Acquisition Proposal, such notice to include the terms and conditions of such Acquisition Proposal, request or inquiry (including a copy, if made in writing, or a written summary, if made orally), and the identity of the Person or group making any such Acquisition Proposal, request or inquiry. The Company shall keep Parent informed on a current basis of the status and terms of any such Acquisition Proposal, request or inquiry, and any material developments related thereto.

6.3 Company Board Recommendation.

(a) Subject to the terms of Section 6.3(b) and Section 6.3(c), the Company Board shall recommend that the holders of Company Shares accept the Offer, tender their Company Shares to Acquisition Sub pursuant to the Offer and, if required by the applicable provisions of Delaware Law, adopt this Agreement (the “Company Board Recommendation”).

(b) Neither the Company Board nor any committee thereof shall (i) fail to make the Company Board Recommendation to the holders of the Company Shares, (ii) withhold, withdraw, amend or modify in a manner adverse to Parent, or publicly propose to withhold, withdraw, amend or modify in a manner adverse to Parent, the Company Board Recommendation, (iii) adopt, approve, recommend, endorse or otherwise declare advisable the adoption of any Acquisition Proposal (it being understood that, only with respect to a tender offer or exchange offer, taking a neutral position or no position (other than in a communication made in compliance with Rule 14d-9(f) promulgated under the Exchange Act) with respect to any Acquisition Proposal shall be considered a breach of this clause (iii)), (iv) fail to reaffirm the Company Board Recommendation within three (3) Business Days of a written request to do so by Parent, (v) in the case of Acquisition Proposal that is a tender or exchange offer, fail to have filed within ten (10) Business Days after the public announcement of the commencement of such Acquisition Proposal a Schedule 14D-9 pursuant to Rule 14e-2 and Rule 14d-9 promulgated under the Exchange Act recommending that the Company Stockholders reject such Acquisition Proposal and not tender any shares of Company Common Stock into such tender or exchange offer, or (vi) resolve, agree or publicly propose to take any such actions (each such foregoing action or failure to act in clauses (i) through (vi) being referred to herein as a “Company Board Recommendation Change”); provided, however, that a “stop, look and listen” communication by the Company Board to the Company Stockholders pursuant to and in compliance with Rule 14d-9(f) of the Exchange Act, or any substantially similar communication following the public announcement or disclosure of any Acquisition Proposal that is not a tender offer or exchange offer that is limited to the information permitted by such rule, shall not be deemed to be a Company Board Recommendation Change. Notwithstanding the foregoing or anything to the contrary set forth in this Agreement, if, at any time prior to the Appointment Time, the Company Board receives a Superior Proposal or there occurs an Intervening Event, the Company Board may effect a Company Board Recommendation Change provided that (i) the Company Board determines in good faith (after consultation with outside legal counsel) that the failure to effect a Company Board Recommendation Change would reasonably be expected to be a breach of its fiduciary duties to the Company Stockholders under applicable Delaware Law, and in the case of a Superior Proposal, the Company Board approves or recommends such Superior Proposal; (ii) the Company has notified Parent in writing that it intends to effect a Company Board Recommendation Change, describing in reasonable detail the reasons, including the material terms and conditions of any such Superior Proposal and a copy of the final form of any related agreements or a description in reasonable detail of such Intervening Event, as the case may be, for such Company Board Recommendation Change (a “Recommendation Change Notice”) (it being understood that the Recommendation Change Notice and any amendment or update to such notice and the determination to so deliver such notice, or update or amend public disclosures with respect thereto shall not constitute a Company Board Recommendation Change for purposes of this Agreement); (iii) if requested by Parent, the Company shall have made its Representatives available to discuss and negotiate in good faith with Parent’s Representatives any proposed modifications to the terms and conditions of this Agreement during the period beginning at 5:00 p.m. Pacific Time on the day of delivery by the Company to Parent of such Recommendation Change Notice and ending three (3) Business Days later at 5:00 p.m. Pacific Time; and (iv) if Parent shall have delivered to the Company a written proposal capable of being accepted by the Company to alter the terms or conditions of this Agreement during such three (3) Business Day

period, the Company Board shall have determined in good faith (after consultation with outside legal counsel), after considering the terms of such proposal by Parent, that the failure to effect a Company Board Recommendation Change would still reasonably be expected to be a breach of its fiduciary duties to the Company Stockholders under Delaware Law. Any material amendment or modification to any Superior Proposal or any material change to an Intervening Event will be deemed to be a new Superior Proposal or Intervening Event for purposes of this Section 6.3 (and require a new three (3) Business Day period, measured as set forth above). The Company shall keep confidential any proposals made by Parent to revise the terms of this Agreement, other than in the event of any amendment to this Agreement and to the extent required to be disclosed in any Company SEC Reports. Effective as of any such Company Board Recommendation Change, Sections 9 and 10 of the Confidentiality Agreement shall become null and void and of no further force and effect.

(c) Nothing in this Agreement shall prohibit the Company Board from (i) taking and disclosing to the Company Stockholders a position contemplated by Rule 14e-2(a) under the Exchange Act or complying with the provisions of Rule 14d-9 promulgated under the Exchange Act, and (ii) making any disclosure to the Company Stockholders that the Company Board determines in good faith (after consultation with its outside legal counsel) that the failure to make such disclosure would reasonably be expected to be a breach of its fiduciary duties to the Company Stockholders under Delaware Law; provided that, in either such case, any such statement(s) or disclosures made by the Company Board will be subject to the terms and conditions of this Agreement, including the provisions of Article X.

6.4 Access. At all times during the period commencing with the execution and delivery of this Agreement and continuing until the earlier to occur of the termination of this Agreement pursuant to Article X and the Appointment Time, the Company shall afford Parent and its financial advisors, business consultants, legal counsel, accountants and other agents and representatives reasonable access during normal business hours, upon reasonable notice, to the properties, books and records and personnel of the Company; provided, however, that the Company may restrict or otherwise prohibit access to any documents or information to the extent that (i) any applicable Law requires the Company to restrict or otherwise prohibit access to such documents or information or (ii) access to such documents or information would give rise to a material risk of waiving any attorney-client privilege, work product doctrine or other applicable privilege applicable to such documents or information; provided, that no information or knowledge obtained by Parent in any investigation conducted pursuant to the access contemplated by this Section 6.4 shall affect or be deemed to modify any representation or warranty of the Company set forth in this Agreement or otherwise impair the rights and remedies available to Parent and Acquisition Sub hereunder and provided, further, that the parties hereto shall use reasonable efforts to provide for appropriate procedures to ensure the confidentiality of any information disclosed pursuant to this Section 6.4. In the event that the Company does not provide access or information in reliance on the preceding sentence, it shall use its reasonable best efforts to communicate the applicable information to Parent in a way that would not violate the applicable Law or to waive such a privilege. Any investigation conducted pursuant to the access contemplated by this Section 6.4 shall be conducted in a manner that does not unreasonably interfere with the conduct of the business of the Company and its Subsidiaries or create a risk of damage or destruction to any property or assets of the Company or any of its

Subsidiaries. Any access to the Company’s properties shall be subject to the Company’s reasonable security measures and insurance requirements and shall not include the right to perform invasive testing. The terms and conditions of the Confidentiality Agreement shall apply to any information obtained by Parent or any of its financial advisors, business consultants, legal counsel, accountants and other agents and representatives in connection with any investigation conducted pursuant to the access contemplated by this Section 6.4.

6.5 Certain Litigation. The Company shall promptly advise Parent of any litigation commenced after the date hereof against the Company or any of its directors (in their capacity as such) by any Company Stockholders (on their own behalf or on behalf of the Company) relating to this Agreement or the transactions contemplated hereby, and shall keep Parent reasonably informed regarding any such litigation. The Company shall give Parent the opportunity to participate in the defense or settlement of any such stockholder litigation and agrees that it shall not settle or offer to settle any such stockholder litigation without the prior written consent of Parent (which consent shall not be unreasonably withheld, conditioned or delayed).

6.6 Section 16(b) Exemption. The Company shall take all actions reasonably necessary to cause the transactions contemplated by this Agreement and any other dispositions of equity securities of the Company (including derivative securities) in connection with the transactions contemplated by this Agreement by each individual who is a director or executive officer of the Company to be exempt under Rule 16b-3 promulgated under the Exchange Act.

ARTICLE VII

COVENANTS OF PARENT AND ACQUISITION SUB

7.1 Directors’ and Officers’ Indemnification and Insurance.

(a) The Surviving Corporation and its Subsidiaries shall (and Parent shall cause the Surviving Corporation and its Subsidiaries to) honor and fulfill in all respects the obligations of the Company and its Subsidiaries under any and all indemnification agreements between the Company or any of its Subsidiaries and any of their respective current or former directors and officers and any person who becomes a director or officer of the Company or any of its Subsidiaries prior to the Appointment Time (the “Indemnified Persons”). In addition, during the period commencing at the Appointment Time and ending on the sixth anniversary of the Effective Time, the Surviving Corporation and its Subsidiaries shall (and Parent shall cause the Surviving Corporation and its Subsidiaries to) cause the certificates of incorporation and bylaws (and other similar organizational documents) of the Surviving Corporation and its Subsidiaries to contain provisions with respect to indemnification, exculpation and the advancement of expenses that are at least as favorable as the indemnification, exculpation and advancement of expenses provisions contained in the certificates of incorporation and bylaws (or other similar organizational documents) of the Company and its Subsidiaries as of the date hereof, and during such six-year period, such provisions shall not be repealed, amended or otherwise modified in any manner except as required by applicable Law.

(b) Without limiting the generality of the provisions of Section 7.1(a), during the period commencing at the Appointment Time and ending on the sixth anniversary of the

Effective Time, to the fullest extent permitted by applicable Law, the Surviving Corporation and its Subsidiaries shall (and Parent shall cause the Surviving Corporation and its Subsidiaries to) indemnify and hold harmless each Indemnified Person from and against any costs, fees and expenses (including reasonable attorneys’ fees and investigation expenses), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any claim, proceeding, investigation or inquiry, whether civil, criminal, administrative or investigative, to the extent such claim, proceeding, investigation or inquiry arises directly or indirectly out of or pertains directly or indirectly to (i) any action or omission or alleged action or omission in such Indemnified Person’s capacity as a director, officer, employee or agent of the Company or any of its Subsidiaries or other Affiliates (regardless of whether such action or omission, or alleged action or omission, occurred prior to, at or after the Effective Time), or (ii) any of the transactions contemplated by this Agreement; provided, however, that if, at any time prior to the sixth anniversary of the Effective Time, any Indemnified Person delivers to Parent a written notice asserting a claim for indemnification under this Section 7.1(b), then the claim asserted in such notice shall survive the sixth anniversary of the Effective Time until such time as such claim is fully and finally resolved. In addition, during the period commencing at the Appointment Time and ending on the sixth anniversary of the Effective Time, to the fullest extent permitted by applicable Law, the Surviving Corporation and its Subsidiaries shall (and Parent shall cause the Surviving Corporation and its Subsidiaries to) advance, prior to the final disposition of any claim, proceeding, investigation or inquiry for which indemnification may be sought under this Agreement, promptly following request by an Indemnified Person therefor, all costs, fees and expenses (including reasonable attorneys’ fees and investigation expenses) incurred by such Indemnified Person in connection with any such claim, proceeding, investigation or inquiry upon receipt of an undertaking by such Indemnified Person to repay such advances if it is ultimately decided in a final, non-appealable judgment by a court of competent jurisdiction that such Indemnified Person is not entitled to indemnification. In the event of any such claim, proceeding, investigation or inquiry, (i) the Surviving Corporation shall have the right to control the defense thereof after the Effective Time (it being understood that, by electing to control the defense thereof, the Surviving Corporation will be deemed to have waived any right to object to the Indemnified Person’s entitlement to indemnification hereunder with respect thereto), (ii) each Indemnified Person shall be entitled to retain his or her own counsel, whether or not the Surviving Corporation shall elect to control the defense of any such claim, proceeding, investigation or inquiry, (iii) the Surviving Corporation shall pay all reasonable fees and expenses of any counsel retained by an Indemnified Person, promptly after statements therefor are received, whether or not the Surviving Corporation shall elect to control the defense of any such claim, proceeding, investigation or inquiry, and (iv) no Indemnified Person shall be liable for any settlement effected without his or her prior express written consent. Notwithstanding anything to the contrary set forth in this Section 7.1(b) or elsewhere in this Agreement, neither the Surviving Corporation nor any of its Affiliates (including Parent) shall settle or otherwise compromise or consent to the entry of any judgment or otherwise seek termination with respect to any claim, proceeding, investigation or inquiry for which indemnification may be sought by an Indemnified Person under this Agreement unless such settlement, compromise, consent or termination includes an unconditional release of all Indemnified Persons from all liability arising out of such claim, proceeding, investigation or inquiry.

(c) During the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) maintain in effect the Company’s current directors’ and officers’ liability insurance (“D&O Insurance”) in respect of acts or omissions occurring at or prior to the Effective Time, covering each person covered by the D&O Insurance, on terms with respect to the coverage and amounts that are equivalent to those of the D&O Insurance; provided, however, that in satisfying its obligations under this Section 7.1(c), Parent and the Surviving Corporation shall not be obligated to pay annual premiums in excess of three hundred percent (300%) of the amount paid by the Company for coverage for its last full fiscal year (such three hundred percent (300%) amount, the “Maximum Annual Premium”) (which premiums the Company represents and warrants to be as set forth in Section 7.1(c) of the Company Disclosure Letter); provided that, if the annual premiums of such insurance coverage exceed such amount, Parent and the Surviving Corporation shall be obligated to obtain a policy with the greatest coverage available for a cost not exceeding the Maximum Annual Premium. Prior to the Effective Time, notwithstanding anything to the contrary set forth in this Agreement, the Company or Parent may, purchase a six-year “tail” prepaid policy on the D&O Insurance, provided that the aggregate annual premium for such “tail policy” shall not exceed 300% of the annual premium paid by the Company for its existing directors’ and officers’ liability insurance policies during the year ended December 31, 2009. In the event that the Company or Parent elects to purchase such a “tail” policy prior to the Effective Time, the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) maintain such “tail” policy in full force and effect and continue to honor their respective obligations thereunder, in lieu of all other obligations of Parent and the Surviving Corporation under the first sentence of this Section 7.1(c) for so long as such “tail” policy shall be maintained in full force and effect.

(d) If Parent or the Surviving Corporation or any of its successors or assigns shall (i) consolidate with or merge into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfer all or substantially all of its properties and assets to any Person, then, and in each such case, proper provisions shall be made so that the successors and assigns of the Surviving Corporation shall assume all of the obligations of Parent and the Surviving Corporation set forth in this Section 7.1.

(e) The obligations set forth in this Section 7.1 shall not be terminated, amended or otherwise modified in any manner that adversely affects any Indemnified Person (or any other person who is a beneficiary under the D&O Insurance or the “tail” policy referred to in Section 7.1(c) (or their heirs and representatives)) without the prior written consent of such affected Indemnified Person or other person who is a beneficiary under the D&O Insurance or the “tail” policy referred to in Section 7.1(c) (or their heirs and representatives). Each of the Indemnified Persons or other persons who are beneficiaries under the D&O Insurance or the “tail” policy referred to in Section 7.1(c) (or their heirs and representatives) are intended to be third party beneficiaries of this Section 7.1, with full rights of enforcement as if a party thereto. The rights of the Indemnified Persons (and other persons who are beneficiaries under the D&O Insurance or the “tail” policy referred to in Section 7.1(c) (or their heirs and representatives)) under this Section 7.1 shall be in addition to, and not in substitution for, any other rights that such persons may have under the certificates of incorporation, bylaws or other equivalent organizational documents, any and all indemnification agreements of or entered into by the Company or any of its Subsidiaries, or applicable Law (whether at law or in equity).

(f) The obligations and liability of Parent, the Surviving Corporation and their respective Subsidiaries under this Section 7.1 shall be joint and several.

(g) Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to the Company or any of its Subsidiaries for any of their respective directors, officers or other employees, it being understood and agreed that the indemnification provided for in this Section 7.1 is not prior to or in substitution for any such claims under such policies.

7.2 Employee Matters.

(a) Parent hereby acknowledges that a “change of control” (or similar phrase) within the meaning of the Employee Plans, as applicable, will occur as of the Appointment Time, as applicable.

(b) From and after the Effective Time, the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) honor all Employee Plans and compensation arrangements in accordance with their terms as in effect immediately prior to the Appointment Time, provided that nothing in this sentence shall prohibit the Surviving Corporation from amending or terminating, or from causing the Surviving Corporation to amend or terminate, any such Employee Plans, arrangements or agreements in accordance with their terms or if otherwise required by applicable Law.

(c) For a period of one year following the Effective Time, the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) either (i) maintain for the benefit of each Continuing Employee, the Employee Plans (or substitute plans) at benefit levels that are no less than those in effect at the Company or its Subsidiaries on the date of this Agreement (excluding equity based benefits and individual employment agreements), and provide compensation and benefits to each Continuing Employee under such Employee Plans, or (ii) provide compensation, benefits and severance payments (other than equity based benefits and individual employment agreements) to each Continuing Employee that, taken as a whole, are no less favorable in the aggregate than the compensation, benefits and severance payments (other than equity based benefits and individual employment agreements) provided to such Continuing Employee immediately prior to the Appointment Time (“Comparable Plans”), or (iii) provide some combination of (i) and (ii) above such that each Continuing Employee receives compensation, benefits and severance payments (other than equity based benefits and individual employment agreements) that, taken as a whole, are no less favorable in the aggregate than the compensation, benefits and severance payments (other than equity based benefits and individual employment agreements) provided to such Continuing Employee immediately prior to the Appointment Time. In each case, base salary or regular wages as of immediately prior to the Appointment Time shall not be decreased for a period of one year following the Effective Time for any Continuing Employee who continues to be employed by the Surviving Corporation or an Affiliate during that period.

(d) To the extent that an Employee Plan or Comparable Plan is made available to any Continuing Employee on or following the Effective Time, the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) cause to be granted to such Continuing Employee credit for all service with the Company and its Subsidiaries prior to the Effective Time for purposes of eligibility to participate, vesting and entitlement to benefits where length of service is relevant (including for purposes of vacation accrual and severance pay entitlement); provided, however, that such service need not be credited for purposes of accrual of pension benefits or to the extent that it would result in duplication of coverage or benefits. In addition, and without limiting the generality of the foregoing: (i) each Continuing Employee shall be immediately eligible to participate, without any waiting time, in any and all employee benefit plans sponsored by the Surviving Corporation and its Subsidiaries (other than the Employee Plans) (such plans, collectively, the “New Plans”) to the extent coverage under any such New Plan replaces coverage under a comparable Employee Plan in which such Continuing Employee participates immediately before the Appointment Time (such plans, collectively, the “Old Plans”); and (ii) for purposes of each New Plan providing medical, dental, pharmaceutical, vision and/or disability benefits to any Continuing Employee, the Surviving Corporation shall cause all waiting periods, pre-existing condition exclusions, evidence of insurability requirements and actively-at-work or similar requirements of such New Plan to be waived for such Continuing Employee and his or her covered dependents, and the Surviving Corporation shall cause any eligible expenses incurred by such Continuing Employee and his or her covered dependents during any unfinished portion of the plan year of the Old Plan ending on the date such employee’s participation in the corresponding New Plan begins to be given full credit under such New Plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such Continuing Employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in accordance with such New Plan, and (iii) credit the accounts of such Continuing Employees under any New Plan which is a flexible spending plan with any unused balance in the account of such Continuing Employee under the applicable Employee Plan. Any vacation or paid time off accrued but unused by a Continuing Employee as of immediately prior to the Effective Time shall be credited to such Continuing Employee following the Effective Time, and shall not be subject to accrual limits or other forfeiture and shall not limit future accruals.

(e) Notwithstanding anything to the contrary set forth in this Agreement, no provision of this Agreement shall be deemed to (i) guarantee employment for any period of time for, or preclude the ability of Parent or the Surviving Corporation to terminate, any Continuing Employee for any reason, or (ii) subject to the limitations and requirements specifically set forth in this Section 7.2, require Parent or the Surviving Corporation to continue any Employee Plan or prevent the amendment, modification or termination thereof after the Effective Time. No provision of this Agreement shall be deemed to amend any benefit or compensation plan, program, policy or other arrangement of the Company, Parent or any of their Affiliates.

(f) This Section 7.2 shall be binding upon and inure solely to the benefit of each of the parties to this Agreement, and nothing in this Section 7.2, expressed or implied, is

intended to confer upon any other Person any rights or remedies of any nature whatsoever under or by reason of this Section 7.2. Without limiting the foregoing, no provision of this Section 7.2 will create any third party beneficiary rights in any current or former employee, director or consultant of the Company or any of its Subsidiaries in respect of continued employment (or resumed employment) or any other matter.

7.3 Obligations of Acquisition Sub. Parent shall take all action necessary to cause Acquisition Sub and the Surviving Corporation to perform their respective obligations under this Agreement and to consummate the transactions contemplated hereby upon the terms and subject to the conditions set forth in this Agreement.

Notwithstanding anything to the contrary herein, none of Parent, Acquisition Sub or the Company shall be required prior to the Effective Time to pay any consent or other similar fee, “profit sharing” or other similar payment or other consideration (including increased rent or other similar payments or any amendments, supplements or other modifications to (or waivers of) the existing terms of any Contract), or the provision of additional security (including a guaranty) to obtain the consent, waiver or approval of any Person under any Contract.

(d) Notwithstanding anything to the contrary in this Agreement, in connection with any filing or submission required or action to be taken by either Parent or the Company to consummate the Offer and the Merger, in no event shall Parent or any of its Subsidiaries or Affiliates be obligated to propose or agree to accept any undertaking or condition, to enter into any consent decree, to make any divestiture or accept any operational restriction, or take or commit to take any action, in each of the foregoing cases, (i) the effectiveness or consummation of which is not conditional on the consummation of the Offer and the Merger or (ii) that would be reasonably likely to (A) adversely impact the benefits expected to be derived by Parent as a result of the Transactions, other than in a de minimis manner or (B) impose material limitations on Parent’s ownership or operation (or that of any of Parent’s Subsidiaries or Affiliates) of all or more than a de minimis portion of the Company’s business or assets, including Parent’s exercise of rights of full ownership of the Company Shares purchased by Acquisition Sub in the Offer on all stockholder matters. The Company shall agree, if requested by Parent in writing, to commit to take any of the forgoing actions with respect to the assets or business of the Company in furtherance of this Section 8.2; provided, however, that any such action may be conditioned upon the consummation of the Merger and other Transactions contemplated by this Agreement.

8.3 Company Stockholder Meeting; Short-Form Merger.

(a) If the Company Stockholders are required under the DGCL to adopt this Agreement in order to consummate the Merger, the Company shall establish a record date for, call, give notice of, convene and hold a meeting of the Company Stockholders (the “Company Stockholder Meeting”) as promptly as practicable following the Appointment Time and the end of any “subsequent offering period” permitted pursuant to this Agreement for the purpose of voting upon the adoption of this Agreement in accordance with the DGCL.

(b) If the Company Stockholders are required under the DGCL to adopt this Agreement in order to consummate the Merger, each of Parent and Acquisition Sub shall vote all Company Shares acquired in the Offer (or otherwise beneficially owned by it or any of its respective wholly-owned Subsidiaries as of the applicable record date) in favor of the adoption of

this Agreement in accordance with the DGCL at the Company Stockholder Meeting or otherwise. Parent shall vote all of the shares of capital stock of Acquisition Sub beneficially owned by it, or sign a written consent in lieu of a meeting of the stockholders of Acquisition Sub, in favor of the adoption of this Agreement in accordance with the DGCL.

(c) Notwithstanding the provisions of this Section 8.3, in the event that Parent, Acquisition Sub or any other Subsidiary of Parent, shall hold at least ninety percent (90%) of the issued and outstanding Company Shares following the consummation of the Offer, each of Parent, Acquisition Sub and the Company shall take all necessary and appropriate action to cause the Merger to become effective as soon as practicable after such acquisition, without a meeting of the stockholders of the Company, in accordance with Section 253 of the DGCL.

8.4 Proxy Statement.

(a) If the Company Stockholders are required under the DGCL to adopt this Agreement in order to consummate the Merger, as soon as practicable following the Appointment Time and the end of any “subsequent offering period” permitted pursuant to this Agreement, the Company, Parent and Acquisition Sub shall jointly prepare, and the Company shall file with the SEC, the Proxy Statement for use in connection with the solicitation of proxies from the Company Stockholders for use at the Company Stockholder Meeting. The Company, Parent and Acquisition Sub, as the case may be, shall furnish all information concerning the Company, on the one hand, and Parent and Acquisition Sub (and their respective Affiliates, if applicable), on the other hand, as the other may reasonably request in connection with the preparation and filing with the SEC of the Proxy Statement. Subject to applicable Law, the Company shall use reasonable best efforts to cause the Proxy Statement to be disseminated to the Company Stockholders as promptly as practicable following the filing thereof with the SEC and confirmation from the SEC that it will not comment on, or that it has no additional comments on, the Proxy Statement. Each of the Company, Parent and Acquisition Sub shall promptly correct any information provided by it or any of its respective directors, officers, employees, affiliates, agents or other representatives for use in the Proxy Statement if and to the extent that such information shall have become false or misleading in any material respect. The Company shall take all steps necessary to cause the Proxy Statement, as so corrected, to be filed with the SEC and disseminated to the Company Stockholders, in each case as and to the extent required by applicable Laws. The Company shall provide Parent, Acquisition Sub and their counsel a reasonable opportunity to review and comment on the Proxy Statement prior to the filing thereof with the SEC, and the Company shall give reasonable and good faith consideration to any comments made by Parent, Acquisition Sub and their counsel (it being understood that Parent, Acquisition Sub and their counsel shall provide any comments thereon as soon as reasonably practicable). The Company shall provide in writing to Parent, Acquisition Sub and their counsel any comments or other communications, whether written or oral, the Company or its counsel may receive from the SEC or its staff with respect to the Proxy Statement promptly after such receipt, and the Company shall provide Parent, Acquisition Sub and their counsel a reasonable opportunity to participate in the formulation of any response to any such comments of the SEC or its staff (including a reasonable opportunity to review and comment on any such response, to which the Company shall give reasonable and good faith consideration to any comments made by Parent, Acquisition Sub and their counsel) and, to the extent deemed appropriate by the Company in its reasonable discretion, to participate in any discussions with the SEC or its staff regarding any such comments.

(b) Unless this Agreement is earlier terminated pursuant to Article X, subject to the terms of Section 6.3(b), the Company shall include the portion of the Company Board Recommendation relating to the Merger and the adoption of this Agreement in the Proxy Statement.

8.5 Anti-Takeover Laws. In the event that any state anti-takeover or other similar Law is or becomes applicable to this Agreement or any of the transactions contemplated by this Agreement, the Company, Parent and Acquisition Sub shall use their respective reasonable best efforts to ensure that (a) such state anti-takeover or other similar Law is rendered inapplicable to this Agreement or any of the transactions contemplated by this Agreement and (b) the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms and subject to the conditions set forth in this Agreement and otherwise to minimize the effect of such Law on this Agreement and the transactions contemplated hereby.

8.6 Notification of Certain Matters.

(a) At all times during the period commencing with the execution and delivery of this Agreement and continuing until the earlier to occur of the termination of this Agreement pursuant to Article X and the Appointment Time, the Company shall give prompt notice to Parent and Acquisition Sub upon becoming aware that any representation or warranty made by it in this Agreement has become untrue or inaccurate in any material respect, or of any failure of the Company to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, in any such case if and only to the extent that such untruth or inaccuracy, or such failure, would reasonably be expected to cause any of the conditions to the obligations of Parent and Acquisition Sub to consummate the transactions contemplated hereby set forth in paragraphs (C)(2) and (C)(3) of Annex A to fail to be satisfied at the then scheduled expiration of the Offer; provided, however, that no such notification shall affect or be deemed to modify any representation or warranty of the Company set forth in this Agreement or the conditions to the obligations of Parent and Acquisition Sub to consummate the transactions contemplated by this Agreement or the remedies available to the parties hereunder or the obligations of the Company under Section 6.4; and provided further, that the terms and conditions of the Confidentiality Agreement shall apply to any information provided to Parent pursuant to this Section 8.6(a).

(b) At all times during the period commencing with the execution and delivery of this Agreement and continuing until the earlier to occur of the termination of this Agreement pursuant to Article X and the Appointment Time, Parent shall give prompt notice to the Company upon becoming aware that any representation or warranty made by Parent or Acquisition Sub in this Agreement has become untrue or inaccurate in any material respect, or of any failure of Parent or Acquisition Sub to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, in any such case if and only to the extent that such untruth or inaccuracy, or such failure, would reasonably be expected to prevent or materially delay the consummation of the transactions

contemplated by this Agreement (including the Offer and the Merger) or the ability of Parent and Acquisition Sub to fully perform their respective covenants and obligations; provided, however, that no such notification shall affect or be deemed to modify any representation or warranty of Parent or Acquisition Sub set forth in this Agreement or the conditions to the obligations of the Company to consummate the transactions contemplated by this Agreement or the remedies available to the parties hereunder; and provided further, that the terms and conditions of the Confidentiality Agreement shall apply to any information provided to the Company pursuant to this Section 8.6(b).

8.7 Public Statements and Disclosure. None of the Company, on the one hand, or Parent and Acquisition Sub, on the other hand, shall issue any public release or make any public announcement concerning this Agreement or the transactions contemplated by this Agreement without the prior written consent of the other (which consent shall not be unreasonably withheld, conditioned or delayed), except as such release or announcement may be required by applicable Law or the rules or regulations of any applicable United States securities exchange or regulatory or Governmental Authority to which the relevant party is subject or submits, wherever situated, in which case the party required to make the release or announcement shall use its reasonable best efforts to allow the other party or parties hereto reasonable time to comment on such release or announcement in advance of such issuance (it being understood that the final form and content of any such release or announcement, as well as the timing of any such release or announcement, shall be at the final discretion of the disclosing party); provided, however, that the restrictions set forth in this Section 8.7 shall not apply to any release or announcement made or proposed to be made by the Company pursuant to Section 6.3 or following a Company Board Recommendation Change.

8.8 Confidentiality. Parent, Acquisition Sub and the Company hereby acknowledge that Parent and the Company have previously executed a Confidentiality Agreement, made as of August 29, 2010 (as amended, the “Confidentiality Agreement”), which, except as otherwise provided in this Agreement, will continue in full force and effect in accordance with its terms.

TERMINATION, AMENDMENT AND WAIVER

10.1 Termination Prior to the Appointment Time. This Agreement may be terminated and the Offer may be abandoned at any time prior to the Appointment Time (it being agreed that the party hereto terminating this Agreement pursuant to this Section 10.1 shall give prompt written notice of such termination to the other party or parties hereto):

(a) by mutual written agreement of Parent and the Company; or

(b) by either Parent or the Company, if the Offer shall have expired or been terminated in accordance with the terms of this Agreement and the Offer without Acquisition Sub having accepted for payment any Company Shares tendered pursuant to the Offer on or before the date that is 90 days following the date hereof (the “Termination Date”; provided, however, that if at such time any of the Antitrust Condition, the Illegality Condition or the Government Litigation Condition has not been satisfied or waived (if permitted hereunder) (but, in the case of the Illegality Condition or the Government Litigation Condition, only to the extent that the failure of such condition to be satisfied or waived is as a result of a Law, Order or Legal Proceeding described therein relating to applicable Antitrust Laws), then the Termination Date shall be extended automatically until the date that is 210 days following the date hereof); provided, however, that the right to terminate this Agreement pursuant to this Section 10.1(b) shall not be available to any party hereto whose action or failure to fulfill any obligation under this Agreement has been the principal cause of or resulted in (i) any of the conditions to the Offer set forth in Annex A having failed to be satisfied and such action or failure to act constitutes a material breach of this Agreement, or (ii) the expiration or termination of the Offer in accordance with the terms of this Agreement and the Offer without Acquisition Sub having accepted for payment any Company Shares tendered pursuant to the Offer and such action or failure to act constitutes a material breach of this Agreement; or

(c) by the Company, in the event that (i) the Company is not then in material breach of its covenants, agreements and other obligations under this Agreement, and (ii) Parent and/or Acquisition Sub shall have breached or otherwise violated any of their respective material covenants, agreements or other obligations under this Agreement, or any of the representations and warranties of Parent and Acquisition Sub set forth in this Agreement shall have become inaccurate, which breach, violation or inaccuracy, individually or in the aggregate with other such breaches, violations or inaccuracies, would reasonably be expected to prevent the consummation

of, or give Parent the right not to consummate, the Offer, and have not been cured, prior to the later of (A) any then scheduled expiration of the Offer or (B) 10 days after the giving of written notice by the Company to Parent and Purchaser of such breach, violation or inaccuracy; or

(d) by Parent, in the event that (i) Parent and Acquisition Sub are not then in material breach of their respective covenants, agreements and other obligations under this Agreement, and (ii) the Company shall have breached or otherwise violated any of its material covenants, agreements or other obligations under this Agreement, or any of the representations and warranties of the Company set forth in this Agreement shall have become inaccurate, in either case such that the events set forth in clauses (C)(2) or (C)(3) of Annex A shall have occurred, and have not been cured, prior to the later of (A) any then scheduled expiration of the Offer or (B) 10 days after the giving of written notice by Parent to the Company of such breach, violation or inaccuracy; or

(e) by the Company, in the event that (i) the Company shall have received a Superior Proposal; (ii) the Company Board shall have determined in good faith (after consultation with outside legal counsel) that the failure to enter into a definitive agreement relating to such Superior Proposal would reasonably be expected to be a breach of its fiduciary duties to the Company Stockholders under Delaware Law; (iii) the Company has notified Parent in writing of the Superior Proposal, including the material terms and conditions of any such Superior Proposal and a copy of the form of any related agreements (a “Superior Proposal Notice”) (it being understood that the Superior Proposal Notice and any amendment or update to such notice and the determination to so deliver such notice, or update or amend public disclosures with respect thereto shall not constitute a Company Board Recommendation Change for purposes of this Agreement); (iv) if requested by Parent, the Company shall have made its Representatives available to discuss and negotiate in good faith with Parent’s Representatives any proposed modifications to the terms and conditions of this Agreement during the period beginning at 5:00 p.m. Pacific Time on the day of delivery by the Company to Parent of such Superior Proposal Notice and ending three (3) Business Days later at 5:00 p.m. Pacific Time; (v) if Parent shall have delivered to the Company during such three (3) Business Day period a written proposal capable of being accepted by the Company to alter the terms or conditions of this Agreement during such three (3) Business Day period, the Company Board shall have determined in good faith (after consultation with its financial advisors and outside legal counsel), after considering the terms of such proposal by Parent, that the Superior Proposal giving rise to such Superior Proposal Notice continues to be a Superior Proposal; and (vi) concurrently with the termination of this Agreement, the Company pays Parent the Termination Fee payable to Parent pursuant to Section 10.4(b)(ii); provided that any material amendment or modification to any Superior Proposal will be deemed to be a new Superior Proposal for purposes of this Section 10.1(e) (and require a new (3) Business Day period, measured as set forth above); or

(f) by Parent, in the event that (i) the Company Board or any committee thereof shall have effected a Company Board Recommendation Change or (ii) the Company shall have materially violated or breached any of its obligations and agreements under Section 6.2 or Section 6.3.

10.2 Termination Before or After Appointment Time and Prior to Effective Time. Notwithstanding the prior adoption of this Agreement by the Company Stockholders in accordance with the DGCL, this Agreement may be terminated and the Offer and/or the Merger may be abandoned, at any time prior to the Effective Time (it being agreed that the party hereto terminating this Agreement pursuant to this Section 10.2 shall give prompt written notice of such termination to the other party or parties hereto), by either Parent or the Company if any Governmental Authority of competent jurisdiction shall have (a) enacted, issued or promulgated any Law that is in effect and has the effect of making the consummation the Offer or the Merger illegal, or (b) issued or granted any Order that is in effect and has the effect of making the Offer or the Merger illegal, and such Order has become final and non-appealable.

10.3 Notice of Termination; Effect of Termination. Any proper and valid termination of this Agreement pursuant to Section 10.1 or Section 10.2 shall be effective immediately upon the delivery of written notice of the terminating party to the other party or parties hereto, as applicable. In the event of the termination of this Agreement pursuant to Section 10.1 or Section 10.2, this Agreement shall be of no further force or effect without liability of any party or parties hereto, as applicable (or any director, officer, employee, affiliate, agent or other representative of such party or parties) to the other party or parties hereto, as applicable, except (a) for the terms of Section 8.8, this Section 10.3, Section 10.4 and Article XI, each of which shall survive the termination of this Agreement, and (b) that nothing herein shall relieve any party or parties hereto, as applicable, from liability for any knowing and intentional breach of, or fraud in connection with, this Agreement. In addition to the foregoing, no termination of this Agreement shall affect the obligations of the parties hereto set forth in the Confidentiality Agreement, all of which obligations shall survive termination of this Agreement in accordance with their terms.

10.4 Fees and Expenses.

(a) General. Except as set forth in this Section 10.4, all fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party or parties, as applicable, incurring such expenses whether or not the Offer and/or the Merger is consummated.

(b) Company Payments.

(i) The Company shall pay to Parent $100,000,000.00 (the “Termination Fee”), by wire transfer of immediately available funds to an account or accounts designated in writing by Parent, within two (2) Business Days, in the event that: (A) this Agreement is terminated (1) by Parent or the Company pursuant to Section 10.1(b) (provided, that (x) each of the Antitrust Condition, the Illegality Condition and the Government Litigation Condition is satisfied at the time of such termination pursuant to Section 10.1(b) and (y) the right to terminate this Agreement pursuant to Section 10.1(b) is then available to Parent) or (2) by Parent pursuant to Section 10.1(d) (provided, that there shall not have occurred a breach, violation or inaccuracy of the type that would entitle the Company to terminate this Agreement pursuant to Section 10.1(c), without regard to the notice and lapse of time requirements set forth therein); and (B) following the execution and delivery of this Agreement and prior to the

termination of this Agreement under any of the circumstances described in clause (A) above, an Acquisition Proposal that is an offer or proposal shall have been publicly announced or shall have become publicly disclosed; and (C) within three-hundred and sixty five (365) days following the termination of this Agreement under any of the circumstances described in clause (A) above, the Company enters into a legally binding definitive agreement providing for, or consummates, a Competing Acquisition Transaction (whether or not such Competing Acquisition Transaction is with respect to the Acquisition Proposal referenced in the preceding clause (B)). For purposes of the foregoing, a “Competing Acquisition Transaction” shall have the same meaning as an “Acquisition Transaction” except that all references therein to “more than twenty percent (20%)” shall be deemed to be references to “a majority,” and the reference therein to “eighty percent (80%)” shall be deemed to be a reference to “fifty percent (50%)”.

(ii) In the event that this Agreement is terminated by the Company pursuant to Section 10.1(e), the Company shall pay to Parent the Termination Fee, by wire transfer of immediately available funds to an account or accounts designated in writing by Parent, as a condition to the effectiveness of such termination.

(iii) In the event that this Agreement is terminated by Parent pursuant to Section 10.1(f) (or by the Company pursuant to Section 10.1(b) following any time at which Parent was entitled to terminate this Agreement pursuant to Section 10.1(f)), the Company shall pay to Parent the Termination Fee, by wire transfer of immediately available funds to an account or accounts designated in writing by Parent, within two (2) Business Days.

(c) Single Payment Only. The parties hereto acknowledge and hereby agree that in no event shall the Company be required to pay the Termination Fee on more than one occasion, whether or not the Termination Fee may be payable under more than one provision of this Agreement at the same or at different times and the occurrence of different events.

(d) Liquidated Damages. In the event that Parent shall receive the Termination Fee pursuant to Section 10.4(b), the receipt of such fee shall be deemed to be liquidated damages for any and all losses or damages suffered or incurred by Parent, Acquisition Sub, any of their respective Affiliates or any other Person in connection with this Agreement (and the termination thereof), the transactions contemplated hereby (and the abandonment thereof) or any matter forming the basis for such termination, and none of Parent, Acquisition Sub, any of their respective Affiliates or any other Person shall be entitled to bring or maintain any other claim, action or proceeding against the Company arising out of this Agreement (and the termination thereof), the transactions contemplated hereby (and the abandonment thereof) or any matter forming the basis for such termination.

10.5 Amendment. Subject to applicable Law and subject to the other provisions of this Agreement, this Agreement may be amended by the parties hereto at any time by execution of an instrument in writing signed on behalf of each of Parent, Acquisition Sub and the Company; provided, however, that in the event that this Agreement has been adopted by the Company Stockholders in accordance with Delaware Law, no amendment shall be made to this Agreement that requires the approval of such Company Stockholders under Delaware Law without such approval.

10.6 Extension; Waiver. At any time and from time to time prior to the Effective Time, any party or parties hereto may, to the extent legally allowed and except as otherwise set forth herein, (a) extend the time for the performance of any of the obligations or other acts of the other party or parties hereto, as applicable, (b) waive any inaccuracies in the representations and warranties made to such party or parties hereto contained herein or in any document delivered pursuant hereto and (c) waive compliance with any of the agreements or conditions for the benefit of such party or parties hereto contained herein. Any agreement on the part of a party or parties hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party or parties, as applicable. Any delay in exercising any right under this Agreement shall not constitute a waiver of such right.

ARTICLE XI

11.3 Assignment. No party may assign either this Agreement or any of its rights, interests, or obligations hereunder without the prior written approval of the other parties, except that Parent or Acquisition Sub may assign any or all of its rights, interests and obligations hereunder to one or more direct or indirect wholly-owned Subsidiaries of Parent, but no such assignment shall relieve either Parent or Acquisition Sub, as the case may be, of any of its obligations under this Agreement. Subject to the preceding sentence, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns.

11.4 Entire Agreement. This Agreement and the documents and instruments and other agreements among the parties hereto as contemplated by or referred to herein, including the

Company Disclosure Letter and the Annexes hereto, constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof; provided, however, the Confidentiality Agreement shall not be superseded, shall survive any termination of this Agreement and shall continue in full force and effect until the earlier to occur of (a) the Effective Time and (b) the date on which the Confidentiality Agreement expires in accordance with its terms or is validly terminated by the parties thereto. EACH PARTY HERETO AGREES THAT, EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS AGREEMENT, NEITHER PARENT, ACQUISITION SUB OR ANY OF THEIR AFFILIATES, DIRECTORS, OFFICERS, EMPLOYEES OR REPRESENTATIVES, ON THE ONE HAND, NOR THE COMPANY OR ANY OF ITS AFFILIATES, DIRECTORS, OFFICERS, EMPLOYEES OR REPRESENTATIVES, ON THE OTHER HAND, MAKES ANY REPRESENTATIONS OR WARRANTIES TO THE OTHER, AND EACH PARTY HEREBY DISCLAIMS ANY OTHER REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED (INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE), OR AS TO THE ACCURACY OR COMPLETENESS OF ANY OTHER INFORMATION, MADE (OR MADE AVAILABLE BY) BY ITSELF OR ANY OF ITS REPRESENTATIVES, WITH RESPECT TO, OR IN CONNECTION WITH, THE NEGOTIATION, EXECUTION OR DELIVERY OF THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, NOTWITHSTANDING THE DELIVERY OR DISCLOSURE TO THE OTHER OR THE OTHER’S REPRESENTATIVES OF ANY DOCUMENTATION OR OTHER INFORMATION WITH RESPECT TO ANY ONE OR MORE OF THE FOREGOING.

11.5 Third Party Beneficiaries. This Agreement is not intended to, and shall not, confer upon any other Person any rights or remedies hereunder, except (a) as set forth in or contemplated by the terms and provisions of Section 7.1, (b) from and after the Appointment Time, the rights of holders of shares of the Company Common Stock and other Company Securities to receive the consideration pursuant to the Offer, as set forth in Article II, and (c) from and after the Effective Time, the rights of holders of shares of the Company Common Stock and other Company Securities to receive the consideration pursuant to the Merger, as set forth in Article III. Parent and Acquisition Sub hereby expressly acknowledge and agree that, prior to the Effective Time, the Company’s measure of damages for a willful and material breach of this Agreement by Parent or Acquisition Sub may include the loss of the economic benefits of the transaction to Company Stockholders and other relief (including equitable relief), whether or not this Agreement has been validly terminated pursuant to Article IX.

11.6 Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement will continue in full force and effect and the application of such provision to other persons or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto. The parties further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

11.7 Remedies.

(a) Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy.

(b) The parties hereto hereby agree that irreparable damage would occur in the event that any provision of this Agreement were not performed in accordance with its specific terms or were otherwise breached, and that money damages or other legal remedies would not be an adequate remedy for any such damages. Accordingly, the parties hereto acknowledge and hereby agree that in the event of any breach or threatened breach by the Company, on the one hand, or Parent and/or Acquisition Sub, on the other hand, of any of their respective covenants or obligations set forth in this Agreement, the Company, on the one hand, and Parent and Acquisition Sub, on the other hand, shall be entitled to an injunction or injunctions to prevent or restrain breaches or threatened breaches of this Agreement, by the other (as applicable), and to specifically enforce the terms and provisions of this Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of the other under this Agreement. The Company, on the one hand, and Parent and Acquisition Sub, on the other hand, hereby agree not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches or threatened breaches of this Agreement by such party (or parties), and to specifically enforce the terms and provisions of this Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of such party (or parties) under this Agreement.
