This AGREEMENT AND PLAN OF REORGANIZATION (this “Agreement”), dated as of March 4, 2015, is by and among AbbVie Inc., a Delaware corporation (“Parent”), Oxford Amherst Corporation, a Delaware corporation and a direct wholly owned subsidiary of Parent (“Purchaser”), Oxford Amherst LLC, a Delaware limited liability company and a direct wholly owned subsidiary of Parent (“Merger Sub 2” and, together with Purchaser, the “Merger Subs”), and Pharmacyclics, Inc., a Delaware corporation (the “Company”). All capitalized terms used in this Agreement shall have the meanings ascribed to such terms in Annex A or as otherwise defined elsewhere in this Agreement unless the context clearly provides otherwise. Parent, each of the Merger Subs and the Company are each sometimes referred to herein as a “Party” and collectively as the “Parties”.

RECITALS

WHEREAS, it is proposed that Purchaser shall commence a tender offer (the “Offer”) to acquire all of the outstanding shares of common stock, $0.0001 par value per share, of the Company (the “Company Common Stock” or, such shares, “Company Shares”) for the consideration and upon the terms and subject to the conditions set forth herein;

WHEREAS, it is also proposed that, as soon as practicable following the consummation of the Offer, the Parties wish to effect the acquisition of the Company by Parent through (a) the merger of Purchaser with and into the Company, with the Company being the surviving entity (the “First Merger”) and (b) immediately following the First Merger, the merger of the Company, as the surviving entity of the First Merger, with and into Merger Sub 2, with Merger Sub 2 being the surviving entity (the “Second Merger” and, together with the First Merger, the “Mergers”);

WHEREAS, the First Merger will be governed by Section 251(h) of the DGCL and will be effected as soon as practicable following the consummation of the Offer upon the terms and subject to the conditions set forth herein;

WHEREAS, in connection with the First Merger, each outstanding share of Company Common Stock issued and outstanding immediately prior to the First Effective Time (other than Cancelled Shares or Dissenting Shares) will be automatically converted into the right to receive the Merger Consideration upon the terms and conditions set forth in this Agreement and in accordance with the General Corporation Law of the State of Delaware (the “DGCL”);

WHEREAS, the Offer and the Mergers have been structured to qualify as a “reorganization” within the meaning of Section 368(a) of the Code when considered together;

WHEREAS, the board of directors of the Company (the “Company Board of Directors”) (i) unanimously determined that the terms of this Agreement and the transactions contemplated hereby (the “Transactions”), including the Offer and the First Merger in connection therewith are fair to, and in the best interests of, the Company and its stockholders, (ii) determined that it is in the best interests of the Company and its stockholders, and declared it advisable, to enter into this

1

Agreement, (iii) approved the execution and delivery by the Company of this Agreement, the performance by the Company of its covenants and agreements contained herein and the consummation of the Offer, the Mergers and the other Transactions upon the terms and subject to the conditions contained herein and (iv) resolved to recommend that the holders of shares of Company Common Stock accept the Offer and tender their shares of Company Common Stock to Purchaser pursuant to the Offer (the “Company Board Recommendation”);

WHEREAS, the board of directors or sole member, as applicable, of Parent and each of the Merger Subs have approved this Agreement and determined that this Agreement and the Transactions, including the Offer, the Mergers and the issuance of Parent Common Stock in the Offer and the First Merger, are advisable and fair to, and in the best interests of, Parent and each of the Merger Subs and its stockholders or members, as applicable;

WHEREAS, as an inducement to and condition of Parent’s willingness to enter into this Agreement, concurrently with the entry of the parties into this Agreement, Robert W. Duggan is entering into a support agreement with Parent (the “Support Agreement”), pursuant to which, among other things, Mr. Duggan agrees to tender all Company Shares beneficially owned by him into the Offer; and

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

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

ARTICLE I

THE OFFER

Section 1.1.                                 The Offer.

(a)                                 Terms and Conditions of the Offer.  Provided that this Agreement shall not have been terminated pursuant to Article IX, as promptly as practicable after the date hereof (but in no event more than thirteen (13) business days thereafter), Purchaser shall (and Parent shall cause Purchaser 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.  In the Offer, each Company Share accepted by Purchaser in accordance with the terms and subject to the conditions of the Offer and in compliance with applicable Law shall be exchanged for the right to receive, at the election of the holder: (i) $$261.25 in cash (the “Cash Consideration”), (ii) a number of shares of Parent Common Stock equal to (x) $261.25 divided by (y) the Parent Trading Price (the “Stock Consideration”), or (iii) $152.25 in cash and a number of shares of Parent Common Stock equal to (x) $109.00 divided by (y) the Parent Trading Price (the “Mixed Consideration”), in each case subject to proration as set forth in Section 1.1(c) and the other provisions of this Article I.  The Offer shall be made by means

2

of an offer to purchase (the “Offer to Purchase”) that is disseminated to all of the holders of Company Shares and contains the terms and conditions set forth in this Agreement and in Annex B.  Each of Parent and Purchaser 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 and not withdrawn in accordance with the terms of the Offer a number of Company Shares that, together with the Company Shares then owned by Parent and Purchaser (if any), represents at least a majority of all then outstanding Company Shares (excluding Company Shares tendered pursuant to guaranteed delivery procedures that have not yet been “received,” as such term is defined in Section 251(h) of the DGCL, by the depositary for the Offer pursuant to such procedures); and

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

(b)                                 Purchaser 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, Purchaser may not (and Parent shall not permit Purchaser to) (i) waive the Minimum Condition, or any of the conditions set forth in clauses (A), (C), (D), (E), (F)(1), or (F)(5) of Annex B (provided, that Parent shall (and shall cause Purchaser to) waive the condition set forth in (F)(5) of Annex B upon the written request of the Company), 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 consideration in the Offer or the number of Company Shares sought in the Offer, (C) extends the Offer, other than in a manner required by the provisions of Section 1.1(e), (D) imposes conditions to the Offer other than those set forth in Annex B, (E) modifies the conditions set forth in Annex B, or (F) amends any other term or condition of the Offer in any manner that is adverse to the holders of Company Shares.

(c)                                  Election; Proration; Fractional Shares.

(i)             Subject to the other clauses of this Section 1.1(c), each holder of Company Shares tendered in the Offer shall be entitled to elect (i) the number of Company Shares which such holder desires to exchange for the right to receive the Mixed Consideration (a “Mixed Election”, and such shares, the “Mixed Election Shares”), (ii) the number of Company Shares which such holder desires to exchange for the right to receive the Cash Consideration (a “Cash Election”, and such shares, the “Cash Election Shares”), and (iii) the number of Company Shares which such holder desires to exchange for the right to receive the Stock Consideration (a “Stock Election”, and such shares, the “Stock Election Shares”). Any Cash Election, Stock Election or Mixed Election shall be referred to herein as an “Election,” and shall be made on a form mutually agreed by Parent and the Company for that purpose (a “Form of Election in Offer”), included as part of the letter(s) of election and transmittal accompanying the Offer.

(ii)          Any Election pursuant to the Offer shall have been properly made only if the depositary of the Offer shall have actually received a properly completed Form of Election in

3

Offer by the expiration date of the Offer.  Any Form of Election in Offer may be revoked or changed by the authorized Person properly submitting such Form of Election in Offer, by written notice received by the depositary of the Offer prior to the expiration date of the Offer. In the event a Form of Election in Offer is revoked prior to the expiration date of the Offer, the Company Shares represented by such Form of Election in Offer shall become Mixed Election Shares, except to the extent a subsequent election is properly made with respect to any or all of such Company Shares prior to expiration date of the Offer. Subject to the terms of this Agreement and of the Form of Election in Offer, the depositary of the Offer shall have reasonable discretion to determine whether any election, revocation or change has been properly or timely made and to disregard immaterial defects in the Form of Election in Offers, and any good faith decisions of the depositary of the Offer regarding such matters shall be binding and conclusive. None of Parent, the Company or the depositary of the Offer shall be under any obligation to notify any Person of any defect in a Form of Election in Offer.

(iii)       Notwithstanding any other provision contained in this Agreement, but subject to Section 1.1(c)(iv), Section 1.1(c)(v) and Section 1.1(c)(vi), the Cash Elections and the Stock Elections shall be subject to proration in the following circumstances:

(1)                                 The maximum number of Company Shares validly tendered and not withdrawn in the Offer which shall be eligible to receive the Cash Consideration shall equal (x) 58.3% of the sum of (A) the aggregate number of Company Shares tendered in the Offer (and not validly withdrawn) (excluding Mixed Election Shares and No Election Shares) plus (B) all Dissenting Shares (or Company Shares that were Dissenting Shares as of the Acceptance Time), minus (y) all Dissenting Shares (or Company Shares that were Dissenting Shares as of the Acceptance Time) (the “Maximum Cash Shares in Offer”).

(2)                                 If the total number of Cash Election Shares validly tendered and not withdrawn in the Offer exceeds the Maximum Cash Shares in Offer, such Cash Elections shall be subject to proration as follows:  For each such Cash Election, the number of Company Shares that shall be exchanged for the right to receive the Cash Consideration shall be (A) the total number of Cash Election Shares validly tendered and not withdrawn in the Offer multiplied by (B) the Offer Cash Proration Factor, rounded down to the nearest Company Share. The “Offer Cash Proration Factor” means a fraction (x) the numerator of which shall be the Maximum Cash Shares in Offer and (y) the denominator of which shall be the total number of Cash Election Shares validly tendered and not withdrawn in the Offer. The Cash Election Shares validly tendered and not withdrawn in the Offer that are not exchanged for the right to receive the Cash Consideration in accordance with this Section 1.1(c)(iii)(2) shall instead be exchanged for the right to receive the Stock Consideration.

(3)                                 The maximum number of Company Shares validly tendered and not withdrawn in the Offer which shall be eligible to receive the Stock Consideration shall equal 41.7 % of the sum of (A) the aggregate number of Company Shares tendered in the Offer (and were not validly withdrawn) (excluding Mixed Election Shares and No Election Shares) plus (B) all

4

Dissenting Shares (or Company Shares that were Dissenting Shares as of the Acceptance Time) (the “Maximum Stock Shares in Offer”).

(4)                                 If the total number of Stock Election Shares validly tendered and not withdrawn in the Offer exceeds the Maximum Stock Shares in Offer, such Stock Elections shall be subject to proration as follows:  For each such Stock Election, the number of Company Shares that shall be exchanged for the right to receive the Stock Consideration shall be (A) the total number of Stock Election Shares validly tendered and not withdrawn in the Offer multiplied by (B) the Offer Stock Proration Factor, rounded down to the nearest Company Share. The “Offer Stock Proration Factor” means a fraction (x) the numerator of which shall be the Maximum Stock Shares in Offer and (y) the denominator of which shall be the total number of Stock Election Shares validly tendered and not withdrawn in the Offer. The Stock Election Shares validly tendered and not withdrawn in the Offer that are not exchanged for the right to receive the Stock Consideration in accordance with this Section 1.1(c)(iii)(4) shall instead be exchanged for the right to receive the Cash Consideration.

(iv)      All prorations resulting from either Section 1.1(c)(iii)(2) or Section 1.1(c)(iii)(4) shall be applied on a pro rata basis, such that each holder of Company Shares who tenders Cash Election Shares or Stock Election Shares, as applicable, bears its proportionate share of the proration, based on a percentage of the total Cash Election Shares or Stock Election Shares, as applicable, tendered in the Offer (and not validly withdrawn) by such holder of Company Shares bears to all Cash Election Shares or Stock Election Shares, as applicable, tendered in the Offer (and not validly withdrawn) by all holders of Company Shares.

(v)         Notwithstanding any other provision of this Agreement to the contrary, including Section 1.1(c)(iii)(2) and Section 1.1(c)(iii)(4), but subject to Section 1.1(c)(vi), a sufficient number of Cash Election Shares, No Election Shares and Mixed Election Shares tendered in the Offer (and not validly withdrawn) shall be exchanged for the right to receive Stock Consideration to the extent necessary to secure the tax opinions contemplated by clause (F)(5) of Annex B as a condition to the Offer, with such Company Shares to be selected by a pro rata selection process by the Exchange Agent.

(vi)      Notwithstanding any provision of this Agreement to the contrary, including Section 1.1(c)(v), in no event shall the total number of shares of Parent Common Stock issuable pursuant to the Offer and the Merger and upon exercise or conversion of all convertible securities assumed by Parent in the Merger constitute such a percentage of the total number of outstanding shares of Parent Common Stock the issuance of which would require any stockholder action under the NYSE Rule.

(vii)   Each Company Share tendered in the Offer (and not validly withdrawn) but which is not the subject of a valid Election (a “No Election Share”) received prior to the expiration of the Offer shall be deemed to be tendered to a Mixed Election. In no event shall any Mixed Election Shares or No Election Shares be subject to proration pursuant to Section 1.1(c)(iii)(2) or Section 1.1(c)(iii)(4), but such shares may be subject to proration pursuant to Section 1.1(c)(v) and Section 1.1(c)(vi).

5

(viii)                                                In lieu of any fractional share of Parent Common Stock that otherwise would be issuable pursuant to the Offer, each holder of Company Shares who otherwise would be entitled to receive a fraction of a share of Parent Common Stock pursuant to the Offer (after aggregating all Company Shares tendered in the Offer (and not validly withdrawn) by such holder) will be paid an amount in cash (without interest) equal to such fractional part of a share of Parent Common Stock multiplied by the Parent Trading Price.

(d)                                 Adjustments to the Offer.  The Mixed Consideration, Cash Consideration, the Stock Consideration, the Maximum Cash Shares in Offer, the Offer Cash Proration Factor, the Maximum Stock Shares in Offer and the Offer Stock Proration Factor shall each 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 or Parent Common Stock, as applicable), reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to the number of Company Shares or shares of Parent Common Stock outstanding after the date hereof and prior to Purchaser’s acceptance for payment of, and payment for, Company Shares that are tendered pursuant to the Offer.

(e)                                  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 1.1(e)(i) or anything to the contrary set forth in this Agreement, without the consent of the Company:

(A) Purchaser shall (and Parent shall cause Purchaser to) extend the Offer for any period required by any Law, 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, or to the extent necessary to resolve any comments of the SEC or its staff applicable to the Offer or the Offer Documents; and

(B) in the event that any of the Offer Conditions (including the Minimum Condition) have not been satisfied or waived as of any then scheduled expiration of the Offer, Purchaser shall (and Parent shall cause Purchaser to) extend the Offer for successive extension periods of up to ten (10) business days each in order to further seek to satisfy the Offer Conditions (including the Minimum Condition);

provided, however, that any such extension 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 IX.

6

(iii)       Neither Parent nor Purchaser shall extend the Offer or provide a “subsequent offering period” within the meaning of Rule 14d-11 promulgated under the Exchange Act in any manner other than pursuant to and in accordance with the provisions of Section 1.1(e)(ii) without the prior written consent of the Company.

(iv)      Neither Parent nor Purchaser 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  IX, in which case Purchaser shall (and Parent shall cause Purchaser to) irrevocably and unconditionally terminate the Offer promptly (but in no event more than one (1) business day) after such termination of this Agreement.

(v)         Nothing in this Section 1.1(e)  shall 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 IX.

(f)                                   Payment for Company Shares.  On the terms and subject to conditions set forth in this Agreement and the Offer, Purchaser shall (and Parent shall cause Purchaser to) accept for payment, and pay for, all Company Shares that are validly tendered and not withdrawn in the Offer promptly (within the meaning of Section 14e-1(c) promulgated under the Exchange Act) after the expiration of the Offer (as it may be extended in accordance with Section 1.1(e)(ii)) (such time, the “Acceptance Time”).  Without limiting the generality of the foregoing, Parent shall provide or cause to be provided to Purchaser on a timely basis the funds and shares of Parent Common Stock necessary to pay for any Company Shares that Purchaser becomes obligated to purchase pursuant to the Offer; provided, however, that without the prior written consent of the Company, Purchaser shall not accept for payment or pay for any Company Shares if, as a result, Purchaser would acquire less than the number of Company Shares necessary to satisfy the Minimum Condition.  The consideration in the Offer payable in respect of each Company Share validly tendered and not withdrawn in the Offer shall be paid net to the holder thereof in cash or shares of Parent Common Stock, as applicable, subject to reduction for any applicable withholding taxes payable in respect thereof.  The Company shall register (and shall instruct its transfer agent to register) the transfer of the Company Shares accepted for payment by Purchaser effective immediately after the Acceptance Time.

(g)                                  Schedule TO; Offer Documents; Form S-4.

(i)             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 Purchaser shall:

(1)                                 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, which Schedule TO shall contain (A) as an exhibit the Offer to Purchase and forms of the letter(s) of election and transmittal and summary advertisement, if any, and other customary ancillary documents, in each case, in respect of the Offer and (B) notice to holders of Company Shares informing such holders of their rights of appraisal in

The Form S-4 will include a preliminary prospectus containing the information required under Rule 14d-4(b) promulgated under the Exchange Act (the “Preliminary Prospectus”).

(iii)       Subject to the provisions of Section 6.3, the Offer Documents and the Form S-4 may include a description of the determinations, approvals and recommendations of the Company Board of Directors set forth in Section 1.2(a) that relate to the Offer.  Each of the Company and Parent shall use its reasonable best efforts to (A) have the Form S-4 declared effective under the Securities Act as promptly as practicable after such filing, (B) ensure that the Form S-4 complies in all material respects with the applicable provisions of the Exchange Act or Securities Act, and (C) keep the Form S-4 effective for so long as necessary to complete the First Merger.  The Company shall promptly furnish in writing to Parent and Purchaser all information concerning the Company and its Subsidiaries and the holders of Company Shares that is required by applicable Law to be included in the Offer Documents and the Form S-4 so as to enable Parent and Purchaser to comply with their obligations under this Section 1.1(g).  Parent, Purchaser and the Company shall cooperate in good faith to determine the information regarding the Company that is necessary to include in the Offer Documents and the Form S-4 in order to satisfy applicable Laws.  Each of Parent, Purchaser and the Company shall promptly correct any information provided by it or any of its respective Representatives for use in the Offer Documents and the Form S-4 if and to the extent that such information shall have become false or misleading in any material respect.  Parent and Purchaser shall, with the Company’s reasonable cooperation, take all steps necessary to cause the Offer Documents and the Form S-4, as so corrected, to be filed with the SEC and to be disseminated to the holders of Company Shares, in each case as and to the extent required by applicable Laws, or by the SEC or its staff or Nasdaq.  Parent shall cause the Form S-4 to comply as to form in all material respects with requirements of applicable Law.  Parent and Purchaser shall provide the Company and its counsel a reasonable opportunity to review and comment on the Offer Documents and the Form S-4 prior to the filing thereof with the SEC, and Parent and Purchaser shall give reasonable and good faith consideration to any reasonable comments made by the Company and its

ARTICLE III

TREATMENT OF SECURITIES

Section 3.1.                                 Treatment of Capital Stock.

(a)                                 Treatment of Company Common Stock. At the First Effective Time, by virtue of the First Merger and without any action on the part of the Parties or holders of any securities of the Company or of Purchaser, subject to Section 1.1(a) and any applicable withholding Tax, each Company Share issued and outstanding immediately prior to the First Effective Time (other than any Cancelled Shares and any Dissenting Shares) shall be automatically converted into the right to receive, at the election of the holder, (i) the Mixed Consideration, (ii) the Cash Consideration or (iii) the Stock Consideration (in case, the “Merger Consideration”), in each case subject to proration as set forth in Section 3.1(e) and the other provisions of this Article III.  From and after the First Effective Time, all such Company Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each applicable holder of such Company Shares shall cease to have any rights with respect thereto, except the right to receive the applicable portion of Merger Consideration therefor upon the surrender of such Company Shares in accordance with Section 3.2, including the right to receive, pursuant to Section 3.6, cash in lieu of fractional shares of Parent Common Stock, if any, into which such Company Shares have been converted pursuant to this Section 3.1(a) (the “Fractional Share Consideration”), together with the amounts, if any, payable pursuant to Section 3.2(f).

13

(b)                                 Cancellation of Company Common Stock. At the First Effective Time, all Company Shares owned by the Company, Parent, the Merger Subs or by any of their respective Subsidiaries shall be cancelled and shall cease to exist, and no consideration shall be delivered in exchange therefor (collectively, the “Cancelled Shares”).

(c)                                  Treatment of Purchaser Shares. At the First Effective Time, each issued and outstanding share of common stock, par value $0.01 per share, of Purchaser (the “Purchaser Shares”) shall be automatically converted into and become one fully paid and nonassessable share of common stock of the First Surviving Corporation and shall constitute the only outstanding shares of capital stock of the First Surviving Corporation. From and after the First Effective Time, all certificates representing Purchaser Shares shall be deemed for all purposes to represent the number of shares of common stock of the First Surviving Corporation into which they were converted in accordance with the immediately preceding sentence.

(d)                                 Effect of Second Merger. At the Second Effective Time, by virtue of the Second Merger and without any action on the part of any of the Parties or holders of any securities of the First Surviving Corporation or of Merger Sub 2, (i) each membership interest of Merger Sub 2 issued and outstanding immediately prior to the Second Effective Time shall remain outstanding as a membership interest of the Surviving Company and (ii) all shares of common stock of the First Surviving Corporation shall no longer be outstanding and shall automatically be cancelled and shall cease to exist without any consideration being payable therefor.

(e)                                  Election; Proration.

(i)                                     Subject to the other clauses of this Section 3.1(e), each holder of Company Shares as of immediately prior to the consummation of the First Merger (other than Dissenting Shares and Cancelled Shares) shall be entitled to elect (i) a number of Cash Election Shares, (ii) a number of Stock Election Shares, and (iii) a number of Mixed Election Shares.  Any Cash Election, Stock Election or Mixed Election shall be made on a form mutually agreed by Parent and the Company prior to the Acceptance Time for that purpose (a “Form of Election in Merger”), which shall be mailed to such holders of Company Shares promptly after the Closing Date (such date, the “Mailing Date”).  The deadline for submitting an effective, properly completed Form of Election in Merger to the Exchange Agent shall be 5:00 p.m., New York City time, on the 20th day following the Mailing Date (or such other time and date as the Parties may mutually agree) (the “Election Deadline”).

(ii)                                  Any election shall have been properly made only if the Exchange Agent shall have actually received a properly completed Form of Election in Merger by the Election Deadline. Any Form of Election in Merger may be revoked or changed by the authorized Person properly submitting such Form of Election in Merger, by written notice received by the Exchange Agent prior to the Election Deadline. In the event a Form of Election in Merger is revoked prior to the Election Deadline, the Company Shares represented by such Form of Election in Merger shall become Mixed Election Shares, except to the extent a subsequent election is properly made with respect to any or all of such Company Shares prior to the Election Deadline. Subject to the terms of this Agreement and of the Form of Election in Merger, the Exchange Agent shall have reasonable

14

discretion to determine whether any election, revocation or change has been properly or timely made and to disregard immaterial defects in the Form of Election in Merger, and any good faith decisions of the Exchange Agent regarding such matters shall be binding and conclusive. None of Parent, the Company or the Exchange Agent shall be under any obligation to notify any Person of any defect in a Form of Election in Merger.

(iii)                               Notwithstanding any other provision contained in this Agreement, but subject to Section 3.1(e)(iv), Section 3.1(e)(v) and Section 3.1(e)(vi), the Cash Election Shares and Stock Election Shares eligible to receive Merger Consideration pursuant to Section 3.1(a) shall be subject to proration in the following circumstances:

(1)                                 The maximum number of Company Shares which shall be eligible to receive the Cash Consideration pursuant to Section 3.1(a) shall equal 58.3% of the aggregate number of Company Shares entitled to receive Merger Consideration pursuant to Section 3.1(a) (excluding Mixed Election Shares and the No Election Shares) (the “Maximum Cash Shares in Merger”).

(2)                                 If the total number of Cash Election Shares eligible to receive Merger Consideration pursuant to Section 3.1(a) exceeds the Maximum Cash Shares in Merger, such Cash Elections shall be subject to proration as follows:  For each such Cash Election, the number of Company Shares that shall be converted into the right to receive the Cash Consideration shall be (A) the total number of Cash Election Shares multiplied by (B) the Merger Cash Proration Factor, rounded down to the nearest Company Share.  The “Merger Cash Proration Factor” means a fraction (x) the numerator of which shall be the Maximum Cash Shares in Merger and (y) the denominator of which shall be the aggregate number of Cash Election Shares eligible to receive Merger Consideration pursuant to Section 3.1(a). The Cash Election Shares that were not converted into the right to receive the Cash Consideration in accordance with this Section 3.1(e)(iii)(2) shall be converted into the right to receive the Stock Consideration.

(3)                                 The maximum number of Company Shares which shall be eligible to receive the Stock Consideration pursuant to Section 3.1(a) shall equal 41.7% of the aggregate number of Company Shares entitled to receive Merger Consideration pursuant to Section 3.1(a) (excluding Mixed Election Shares and the No Election Shares) (the “Maximum Stock Shares in Merger”).

(4)                                 If the total number of Stock Election Shares eligible to receive Merger Consideration pursuant to Section 3.1(a) exceeds the Maximum Stock Shares in Merger, such Stock Elections shall be subject to proration as follows:  For each such Stock Election, the number of Company Shares that shall be converted into the right to receive the Stock Consideration shall be (A) the total number of Stock Election Shares multiplied by (B) the Merger Stock Proration Factor, rounded down to the nearest Company Share. The “Merger Stock Proration Factor” means a fraction (x) the numerator of which shall be the Maximum Stock Shares in Merger and (y) the denominator of which shall be the aggregate number of Stock Election Shares eligible to receive Merger Consideration pursuant to Section 3.1(a). The Stock Election Shares that were not converted

15

into the right to receive the Stock Consideration in accordance with this Section 3.1(e)(iii)(4) shall be converted into the right to receive the Cash Consideration.

(iv)                              All prorations resulting from either Section 3.1(c)(iii)(2) or Section 3.1(c)(iii)(4) shall be applied on a pro rata basis, such that each holder of Company Shares bears its proportionate share of the proration, based on a percentage of the total Cash Election Shares or Stock Election Shares, as applicable, elected by such holder of Company Shares bears to all Cash Election Shares or Stock Election Shares, as applicable, elected by holders of Company Shares in the First Merger.

(v)                                 Notwithstanding any other provision of this Agreement to the contrary, but subject to Section 3.1(e)(vi), a sufficient number of Cash Election Shares and No Election Shares and Mixed Election Shares eligible to receive Merger Consideration pursuant to Section 3.1(a) shall be converted into the right to receive Stock Consideration to the same extent as any comparable proration in the Offer pursuant to Section 1.1(c)(v).

(vi)                              Notwithstanding any provision of this Agreement to the contrary, including Section 3.1(e)(v), in no event shall the total number of shares of Parent Common Stock issued pursuant to the Offer and issuable pursuant to the Merger and upon exercise or conversion of all convertible securities assumed by Parent in the Merger constitute such a percentage of the total number of outstanding shares of Parent Common Stock the issuance of which would require any stockholder action under the NYSE Rule.

(f)                                   Adjustment to Merger Consideration. The Merger Consideration, Maximum Cash Shares in Merger, and Merger Cash Proration Factor and Merger Stock Proration Factor 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 or Parent Common Stock, as applicable), reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to the number of Company Shares or Parent Common Stock outstanding after the date hereof and prior to the First Effective Time.

Section 3.2.                                 Payment for Securities; Surrender of Certificates.

(a)                                 Exchange Fund. Prior to the First Effective Time, Parent or Purchaser shall designate a bank or trust company reasonably acceptable to the Company to act as the exchange agent in connection with the First Merger (the “Exchange Agent”). The Exchange Agent shall also act as the agent for the Company’s stockholders for the purpose of receiving and holding their Form of Election in Merger and Certificates and Book-Entry Shares and shall obtain no rights or interests in the shares represented thereby. At or immediately after the First Effective Time, Parent or Purchaser shall deposit, or cause to be deposited, with the Exchange Agent (i) evidence of Parent Common Stock issuable pursuant to Section 3.1(a) in book-entry form equal to the aggregate Parent Common Stock portion of the Merger Consideration (excluding any Fractional Share Consideration), and (ii) cash in immediately available funds in an amount sufficient to pay the aggregate cash portion of the Merger Consideration, Fractional Share Consideration and any dividends under Section 3.2(f) (such evidence of book-entry shares of Parent Common Stock and cash amounts,

16

together with any dividends or other distributions with respect thereto, the “Exchange Fund”), in each case, for the sole benefit of the holders of Company Shares. In the event the Exchange Fund shall be insufficient to pay the aggregate cash portion of the Merger Consideration, Fractional Share Consideration and any dividends under Section 3.2(f), Parent shall, or shall cause Parent or Purchaser to, promptly deposit additional funds with the Exchange Agent in an amount which is equal to the deficiency in the amount required to make such payment. Parent shall cause the Exchange Agent to make, and the Exchange Agent shall make, delivery of the Merger Consideration, including payment of the Fractional Share Consideration, and any amounts payable in respect of dividends or other distributions on shares of Parent Common Stock in accordance with Section 3.2(f) out of the Exchange Fund in accordance with this Agreement. The Exchange Fund shall not be used for any purpose that is not expressly provided for in this Agreement. The cash portion of the Exchange Fund shall be invested by the Exchange Agent as reasonably directed by Parent; provided, however, that any investment of such cash shall in all events be limited to direct short-term obligations of, or short-term obligations fully guaranteed as to principal and interest by, the U.S. government, in commercial paper rated P-1 or A-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation, respectively, or in certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $10 billion (based on the most recent financial statements of such bank that are then publicly available), and that no such investment or loss thereon shall affect the amounts payable to holders of Certificates or Book-Entry Shares pursuant to this Article III. Any interest and other income resulting from such investments shall be paid to the Surviving Company on the earlier of (A) one (1) year after the First Effective Time or (B) the full payment of the Exchange Fund.

(b)                                 Procedures for Surrender. Promptly after the First Effective Time, Parent shall, and shall cause the Surviving Company to, cause the Exchange Agent to mail (and make available for collection by hand) to each holder of record of a certificate or certificates which immediately prior to the First Effective Time represented outstanding Company Shares (the “Certificates”) or non-certificated Company Shares represented by book-entry (“Book-Entry Shares”) and whose Company Shares were converted pursuant to Section 3.1 into the right to receive the Merger Consideration (i) a letter of transmittal, which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates (or affidavits of loss in lieu thereof) to the Exchange Agent and shall be in such form and have such other provisions as Parent may reasonably specify and (ii) instructions for effecting the surrender of the Certificates (or affidavits of loss in lieu thereof) or Book-Entry Shares in exchange for payment of the Merger Consideration into which such Company Shares have been converted pursuant to Section 3.1, including any amount payable in respect of Fractional Share Consideration in accordance with Section 3.6, and any dividends or other distributions on shares of Parent Common Stock in accordance with Section 3.2(f). Upon surrender of a Certificate (or an affidavit of loss in lieu thereof) or Book-Entry Share for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Parent or the Surviving Company, together with such letter of transmittal duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions, the holder of such Certificate or Book-Entry Share shall be entitled to receive in exchange therefor the applicable Merger Consideration pursuant to the provisions of this Article III, any Fractional Share Consideration that

17

such holder has the right to receive pursuant to the provisions of Section 3.6, and any amounts that such holder has the right to receive in respect of dividends or other distributions on shares of Parent Common Stock in accordance with Section 3.2(f) for each Company Share formerly represented by such Certificate or Book-Entry Share, to be mailed (or made available for collection by hand if so elected by the surrendering holder) within five (5) business days following the later to occur of (x) the Election Deadline and the determination of pro ration pursuant to Section 3.1(e) or (y) the Exchange Agent’s receipt of such Certificate (or affidavit of loss in lieu thereof) or Book-Entry Share, and the Certificate (or affidavit of loss in lieu thereof) or Book-Entry Share so surrendered shall be forthwith cancelled. The Exchange Agent shall accept such Certificates (or affidavits of loss in lieu thereof) or Book-Entry Shares upon compliance with such reasonable terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices. If payment of the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate is registered, it shall be a condition precedent of payment that (A) the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and (B) the Person requesting such payment shall have paid any transfer and other similar Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate surrendered or shall have established to the satisfaction of the Surviving Company that such Tax either has been paid or is not required to be paid. Payment of the applicable Merger Consideration with respect to Book-Entry Shares shall only be made to the Person in whose name such Book-Entry Shares are registered. Until surrendered as contemplated by this Section 3.2, each Certificate and Book-Entry Share shall be deemed at any time after the First Effective Time to represent only the right to receive the applicable Merger Consideration as contemplated by this Article III, including any amount payable in respect of Fractional Share Consideration in accordance with Section 3.6, and any dividends or other distributions on shares of Parent Common Stock in accordance with Section 3.2(f), without interest thereon.

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

(d)                                 Termination of Exchange Fund; No Liability. At any time following twelve (12) months after the First Effective Time, Parent shall be entitled to require the Exchange Agent to deliver to it any funds (including any interest received with respect thereto) remaining in the Exchange Fund that have not been disbursed, or for which disbursement is pending subject only to the Exchange Agent’s routine administrative procedures, to holders of Certificates or Book-Entry Shares, and thereafter such holders shall be entitled to look only to the Surviving Company and Parent (subject to abandoned property, escheat or other similar Laws) as general creditors thereof with respect to the applicable Merger Consideration, including any amount payable in respect of Fractional Share Consideration in accordance with Section 3.6, and any dividends or other

18

distributions on shares of Parent Common Stock in accordance with Section 3.2(f), payable upon due surrender of their Certificates or Book-Entry Shares and compliance with the procedures in Section 3.2(b), without any interest thereon. Notwithstanding the foregoing, none of the Surviving Company, Parent or the Exchange Agent shall be liable to any holder of a Certificate or Book-Entry Share for any Merger Consideration or other amounts delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(e)                                  Lost, Stolen or Destroyed Certificates. In the event that any Certificates shall have been lost, stolen or destroyed, the Exchange 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 applicable Merger Consideration payable in respect thereof pursuant to Section 3.1 hereof, including any amount payable in respect of Fractional Share Consideration in accordance with Section 3.6, and any dividends or other distributions on shares of Parent Common Stock in accordance with Section 3.2(f).

(f)                                   Dividends or Distributions with Respect to Parent Common Stock. No dividends or other distributions with respect to Parent Common Stock with a record date after the First Effective Time shall be paid to the holder of any unsurrendered Certificate or Book-Entry Share with respect to the shares of Parent Common Stock issuable hereunder, and all such dividends and other distributions shall be paid by Parent to the Exchange Agent and shall be included in the Exchange Fund, in each case until the surrender of such Certificate or Book-Entry Share (or affidavit of loss in lieu thereof) in accordance with this Agreement. Subject to applicable Laws, following surrender of any such Certificate or Book-Entry Share (or affidavit of loss in lieu thereof) there shall be paid to the holder thereof, without interest, (i) the amount of dividends or other distributions with a record date after the First Effective Time theretofore paid with respect to such shares of Parent Common Stock to which such holder is entitled pursuant to this Agreement and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the First Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such shares of Parent Common Stock.

Section 3.3.                                 Dissenter’s Rights.

(a)                                 Notwithstanding anything to the contrary set forth in this Agreement, Company Shares issued and outstanding immediately prior to the First Effective Time (other than Cancelled Shares) and held by a holder who has not tendered into the Offer and properly exercised appraisal rights in respect of such shares in accordance with Section 262 of the DGCL (such shares being referred to collectively as the “Dissenting Shares” until such time as such holder fails to perfect, withdraws or otherwise loses such holder’s appraisal rights under Delaware Law with respect to such shares) shall not be converted into a right to receive the Merger Consideration but instead shall be entitled to payment of such consideration as may be determined to be due in accordance with Section 262 of the DGCL; provided, however, that if, after the First Effective Time, such holder fails to perfect, withdraws or otherwise loses such holder’s right to appraisal pursuant to Section 262 of the DGCL, or if a court of competent jurisdiction shall determine that such holder is not entitled to the relief provided by Section 262 of the DGCL, such Company Shares shall be

19

treated as if they had been converted as of the First Effective Time into the right to receive the Merger Consideration in accordance with Section 3.1(a), without interest thereon, upon surrender of such Certificate formerly representing such share or transfer of such Book-Entry Shares, as the case may be.

(b)                                 The Company shall give prompt notice to Parent of any demands received by the Company for appraisal of any Company Shares, of any withdrawals of such demands and of any other instruments served pursuant to the DGCL and received by the Company relating to Section 262 of the DGCL, and Parent shall have the opportunity to participate in and direct all negotiations and proceedings with respect to such demands. Prior to the First Effective Time, the Company shall not, without the prior written consent of Parent, make any payment with respect to, or settle or compromise or offer to settle or compromise, any such demand, or agree to do any of the foregoing.

Section 3.4.                                 Treatment of Company Equity Awards.

(a)                                 As of the First Effective Time, each Company Stock Option shall be cancelled and converted into the right to receive cash amount(s) equal to the product of: (i) the total number of Company Shares subject to such Company Stock Option multiplied by (ii) the excess, if any, of (x) the Cash Consideration over (y) the exercise price per Company Share of such Company Stock Option (the “Option Cash Payment”).  With respect to the portion of the Option Cash Payment relating to any Vested Company Stock Option, such Option Cash Payment shall be payable (without interest and less applicable withholding Taxes) in a lump sum promptly following the Closing Date.  With respect to the portion of the Option Cash Payment relating to any Unvested Company Stock Option, the Option Cash Payment shall be payable (without interest and less applicable withholding Taxes) through December 31 of the calendar year in which the Closing Date occurs (the “Delayed Payment Date”) at the same rate as the corresponding Unvested Company Stock Option would have vested under the vesting terms in place immediately prior to the First Effective Time had such Unvested Company Stock Option not been cancelled under this Agreement with any remaining unpaid Option Cash Payment as of the Delayed Payment Date payable (without interest and less applicable withholding Taxes) in a lump sum on or before the Delayed Payment Date, in all cases subject to the holder continuing to provide services to Parent or any of its Subsidiaries following the Closing Date (and further subject to any vesting acceleration provided for in the applicable Company Equity Plan, in any award agreement or other agreement, plan, policy, or arrangement applicable to such Company Stock Option or applicable to such Company Stock Options by reason of this Agreement or the Transactions).  With respect to any Company Stock Option with performance-based vesting conditions that remains outstanding as of immediately prior to the First Effective Time, the performance goals will be deemed achieved at target levels and such Company Stock Option will be vested as of immediately prior to the First Effective Time to the same extent such Company Stock Option would have been had the performance goals been achieved at target levels following the end of the performance period(s) under the vesting schedule applicable to such Company Stock Option in place immediately prior to the First Effective Time.

(b)                                 As of the First Effective Time, each Company RSU shall be cancelled and converted into the right to receive cash amount(s) equal to the product of: (i) the total number of

20

Company RSUs multiplied by (ii) the Cash Consideration (the “RSU Cash Payment”).  With respect to the portion of the RSU Cash Payment relating to any Vested Company RSU, such RSU Cash Payment shall be payable (without interest and less applicable withholding Taxes) in a lump sum promptly following the Closing Date.  With respect to the portion of the RSU Cash Payment relating to any Unvested Company RSU, the RSU Cash Payment shall be payable (without interest and less applicable withholding Taxes) through the Delayed Payment Date at the same rate as the corresponding Unvested Company RSU would have vested under the vesting terms in place immediately prior to the First Effective Time had such Unvested Company RSU not been cancelled under this Agreement with any remaining unpaid RSU Cash Payment payable (without interest and less applicable withholding Taxes) in a lump sum on or before the Delayed Payment Date, in all cases subject to the holder continuing to provide services to Parent or any of its Subsidiaries following the Closing Date (and further subject to any vesting acceleration provided for in the applicable Company Equity Plan, in any award agreement or other agreement, plan, policy, or arrangement applicable to such Company RSUs, or applicable to such Company RSUs by reason of this Agreement or the Transactions).  With respect to any Company RSU with performance-based vesting conditions that remain outstanding as of immediately prior to the First Effective Time, the performance goals will be deemed achieved at target levels and such Company RSU will be vested as of immediately prior to the First Effective Time to the same extent such Company RSU would have been had the performance goals been achieved at target levels following the end of the performance period(s) under the vesting schedule applicable to such Company RSU in place immediately prior to the First Effective Time.

(c)                                  Prior to the First Effective Time, the Company shall pass resolutions as are necessary for the treatment of the Company Equity Awards as contemplated by this Section 3.4.

(d)                                 Prior to the Acceptance Time (i) each outstanding offering period then in progress (each, an “Offering Period”) under the Company’s Employee Stock Purchase Plan (the “ESPP”) shall terminate, (ii) each ESPP participant’s accumulated contributions under the ESPP shall be used to purchase Company Shares in accordance with the terms of the ESPP as of such time, and the funds, if any, that remain in the participants’ accounts after such purchase shall be returned to the participants and (iii) the ESPP shall terminate. No participant may elect to participate in the ESPP after the date of this Agreement, participants may not increase their payroll deduction percentages or purchase elections from those in effect on the date of this Agreement and no new offering period under the ESPP shall commence under the ESPP following the date of this Agreement. Prior to the Acceptance Time, the Company shall pass resolutions as are necessary for the treatment of the purchase rights under the ESPP and the termination of the ESPP as contemplated by this Section 3.4.

Section 3.5.                                 Withholding.  Parent, the Merger Subs, the First Surviving Corporation and the Surviving Company shall be entitled to deduct and withhold, or cause the Exchange Agent to deduct and withhold, from the consideration otherwise payable to a holder of Company Common Stock or Company Equity Awards pursuant to this Agreement, any amounts as are required to be withheld or deducted with respect to such consideration under the Code, or any applicable provisions of state, local or foreign Tax Law. To the extent that amounts are so withheld and timely remitted to

Parent’s disclosure controls and procedures are reasonably designed to ensure that all material information required to be disclosed by Parent in the reports that it files or furnishes under the Exchange Act is recorded, processed, summarized and reported within

42

the time periods specified in the rules and forms of the SEC, and that all such material information is accumulated and communicated to Parent’s management as appropriate to allow timely decisions regarding required disclosure and to make the certifications required pursuant to Sections 302 and 906 of the Sarbanes-Oxley Act.  Since January 1, 2013, Parent’s principal executive officer and its principal financial officer have disclosed to Parent’s auditors and the audit committee of the Parent Board of Directors (a) all known significant deficiencies and material weaknesses in the design or operation of internal controls over financial reporting that are reasonably likely to adversely affect in any material respect Parent’s ability to record, process, summarize and report financial information and (b) any known fraud, whether or not material, that involves management or other employees who have a significant role in Parent’s internal controls.

All Parent Permits are in full force and effect, except where the failure to

43

be in full force and effect would not reasonably be expected to have, individually or in the aggregate, a Parent Material Adverse Effect.

Section 5.10.                          Investigations; Litigation.  As of the date hereof, (a) there is no investigation or review pending (or, to the knowledge of Parent, threatened) by any Governmental Entity with respect to Parent or any of Parent’s Subsidiaries or any of their respective properties, rights or assets, and (b) there are no claims, actions, suits or proceedings pending (or, to the knowledge of Parent, threatened) against Parent or any of Parent’s Subsidiaries or any of their respective properties, rights or assets before, and there are no orders, judgments or decrees of, any Governmental Entity, which, in the case of clause (a) or (b), would reasonably be expected to have, individually or in the aggregate, a Parent Material Adverse Effect.

The Company shall immediately cease, and shall cause its directors, officers, employees and other Representatives to cease, any and all existing discussions or negotiations with any parties (or provision of any nonpublic information to any parties) conducted heretofore with respect to any Acquisition Proposal or potential Acquisition Proposal.  Promptly after the date hereof, the Company shall request that each Person that has heretofore executed a confidentiality agreement relating to an Acquisition Proposal or a potential Acquisition Proposal promptly destroy or return to the Company all non-public information, documents and materials relating to such Acquisition Proposal or to the Company or its businesses, operations or assets heretofore furnished by the Company or any of its Representatives to such Person or group or any of its representatives in accordance with the terms of such confidentiality agreement.  For purposes of this Section 6.3, the term “Person” means any Person or “group,” as defined in Section 13(d) of the Exchange Act, other than, with respect to the Company, Parent or any Parent Subsidiaries or any of their Representatives.

(c)           The Company shall notify Parent promptly (and in any event within twenty-four hours) after receipt of any Acquisition Proposal, any proposals or inquiries that would reasonably be expected to lead to an Acquisition Proposal, or any inquiry or request for nonpublic information relating to the Company or any Company Subsidiary by any Person who has made or would reasonably be expected to make any Acquisition Proposal. Such notice shall indicate the

51

identity of the Person making the Acquisition Proposal, inquiry or request, and the material terms and conditions of any such proposal or offer or the nature of the information requested pursuant to such inquiry or request, including copies of all written requests, proposals or offers, including proposed agreements received by the Company. The Company shall keep Parent reasonably informed on a prompt and timely basis of  the status and material terms (including any amendments or proposed amendments to such material terms) of any such Acquisition Proposal or potential Acquisition Proposal and keep Parent reasonably informed on a prompt and timely basis as to the nature of any information requested of the Company with respect thereto. The Company shall promptly provide to Parent any material nonpublic information concerning the Company provided to any other Person in connection with any Acquisition Proposal that was not previously provided to Parent.

(d)           Notwithstanding anything in this Section 6.3 to the contrary, but subject to Section 6.3(e), at any time prior to the Acceptance Time, the Company Board of Directors may (i) make a Change of Recommendation in response to an Intervening Event (other than for an Acquisition Proposal) if the Company Board of Directors has determined in good faith after consultation with the Company’s outside financial advisors and outside legal counsel, that failure to take such action would reasonably be expected to be inconsistent with the directors’ fiduciary duties under applicable Law, or (ii) make a Change of Recommendation and cause the Company to terminate this Agreement pursuant to Section 9.1(g) in order to enter into an definitive agreement in connection with an unsolicited Acquisition Proposal, which the Company Board of Directors determines in good faith after consultation with the Company’s outside legal and financial advisors is a Superior Proposal if the Company Board of Directors has determined in good faith after consultation with the Company’s outside financial advisors and outside legal counsel, that failure to take such action would reasonably be expected to be inconsistent with the directors’ fiduciary duties under applicable Law.

(e)           Prior to the Company taking any action permitted (i) under Section 6.3(d)(i), the Company shall provide Parent with three (3) business days’ prior written notice advising Parent it intends to effect a Change of Recommendation and specifying, in reasonable detail, the reasons therefor, and during such three (3) business day period, the Company shall, and shall cause its Representatives to, negotiate in good faith any proposal by Parent to amend the terms and conditions of this Agreement in a manner that would obviate the need to effect a Change of Recommendation  and at the end of such three (3) business day period the Company Board of Directors again makes the determination described under Section 6.3(d)(i), or (ii) under Section 6.3(d)(ii), the Company shall provide Parent with three (3) business days’ prior written notice advising Parent that the Company Board of Directors intends to take such action and specifying the material terms and conditions of the Acquisition Proposal, and during such three (3) business day period, the Company shall, and shall cause its Representatives to, negotiate in good faith any proposal by Parent to amend the terms and conditions of this Agreement such that such Acquisition Proposal would no longer constitute a Superior Proposal and at the end of such three (3) business day period the Company Board of Directors again makes the determination described under Section 6.3(d)(ii).  With respect to Section 6.3(e)(ii), if there are any changes to the financial or other material terms of any such Superior Proposal for which notice was previously given by the Company pursuant to Section 

52

6.3(e)(ii) (including any revision to the amount, form or mix of consideration the Company’s stockholders would receive as a result of the Superior Proposal), such change shall require the Company to comply again with Section 6.3(e)(ii) (with references to three (3) business days to be replaced by two (2) business days) prior to making the determination under Section 6.3(d)(ii).

(f)            Nothing contained in this Agreement shall prohibit the Company or the Company Board of Directors from (i) disclosing to the Company’s stockholders a position contemplated by Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act, or any substantially similar communication in connection with any Acquisition Proposal that is not a tender offer, or (ii) making any disclosure to its stockholders if the Company Board of Directors has reasonably determined in good faith after consultation with the Company’s outside legal counsel that the failure to do so would be inconsistent with the director’s duties under applicable Law; provided that this Section 6.3(f) shall not permit the Company Board of Directors to make a Change of Recommendation except to the extent permitted by Section 6.3(d) or Section 6.3(e).

ARTICLE VII

Notwithstanding the foregoing, neither the Company nor Parent shall be required by this Section 7.1 to provide the other Party or the Representatives of such other Party with access to or to disclose information (A) that is subject to the terms of a confidentiality agreement with a third party entered into prior to the date of this Agreement or entered into after the date of this Agreement in the ordinary course of business consistent with past practice (provided, however, that the withholding Party shall use its reasonable best efforts to obtain the required consent of such third party to such access or disclosure or, if unable to do so, to make appropriate substitute arrangements to permit reasonable access or disclosure not in violation of such consent requirement), (B) the disclosure of which would violate any Law or duty (provided, however, that the withholding Party shall use its commercially reasonable efforts to make appropriate substitute arrangements to permit reasonable disclosure not in violation of any Law or duty) or (C) that is subject to any attorney-client, attorney work product or other legal privilege (provided, however, that the withholding Party shall use its reasonable best efforts to allow for such access or disclosure to the maximum extent that does not result in a loss of any such attorney-client,

53

attorney work product or other legal privilege). Each of the Company and Parent will use its commercially reasonable efforts to minimize any disruption to the businesses of the other Party that may result from the requests for access, data and information hereunder.

(b)           Each of the Company and Parent will hold, and will cause its Representatives and affiliates to hold, any nonpublic information, including any information exchanged pursuant to this Section 7.1, in confidence to the extent required by and in accordance with, and will otherwise comply with, the terms of the Confidentiality Agreement.

The failure to deliver any such notice shall not affect any of the conditions set forth in Annex B or give rise to any right to terminate under Article IX.

57

publication of any press release or other public announcement with respect to the Offer, the Mergers or this Agreement, in which event such Party shall endeavor, on a basis reasonable under the circumstances, to provide a meaningful opportunity to the other Party to review and comment upon such press release or other announcement in advance and shall give due consideration to all reasonable additions, deletions or changes suggested thereto; provided, however, that the Company shall not be required by this Section 7.4 to provide any such review or comment to Parent in connection with the receipt and existence of an Acquisition Proposal or a Change of Recommendation and matters related thereto; provided, further, that the Parties shall not be required by this Section 7.4 to provide any such review or comment to the other Party to the event of any dispute between the Parties relating to this Agreement; provided, further, each Party and their respective affiliates or Representatives may make statements that are not inconsistent with previous press releases, public disclosures or public statements made by Parent and the Company in compliance with this Section 7.4.

The Parties agree that all rights to elimination of liability, indemnification and advancement of expenses for acts or omissions occurring or alleged to have occurred at or prior to the First Effective Time, whether asserted or claimed prior to, at or after the First Effective Time, now existing in favor of the Indemnified Parties as provided in their respective certificate of incorporation or by-laws (or comparable organizational documents) or in any agreement shall survive the First Merger and shall continue in full force and effect.  Notwithstanding anything herein to the contrary, if any Indemnified Party notifies the Surviving Company on or prior to the sixth anniversary of the First Effective Time of a matter in respect of which such Person may seek indemnification pursuant to

58

this Section 7.5, the provisions of this Section 7.5 shall continue in effect with respect to such matter until the final disposition of all claims, actions, investigations, suits and proceedings relating thereto.

(b)           For six years after the First Effective Time, the Surviving Company shall cause to be maintained in effect the provisions in (i) the Company Governing Documents and the organizational documents of any Company Subsidiary and (ii) any other agreements of the Company and the Company Subsidiaries with any Indemnified Party, in each case, regarding elimination of liability, indemnification of officers, directors and employees and advancement of expenses that are in existence on the date of this Agreement, and no such provision shall be amended, modified or repealed in any manner that would adversely affect the rights or protections thereunder of any such Indemnified Party in respect of acts or omissions occurring or alleged to have occurred at or prior to the First Effective Time (including acts or omissions occurring in connection with the approval of this Agreement and the consummation of the Offer, the Mergers or any of the other Transactions).

(c)           Parent shall cause the Surviving Company to provide, for an aggregate period of not less than six (6) years from the First Effective Time, the Company’s current directors and officers an insurance and indemnification policy that provides coverage for events occurring prior to the First Effective Time (the “D&O Insurance”) that is no less favorable than the Company’s existing policy or, if insurance coverage that is no less favorable is unavailable, the best available coverage; provided, however, that the Surviving Company shall not be required to pay an annual premium for the D&O Insurance in excess of three hundred percent (300%) of the last annual premium paid prior to the date of this Agreement; provided, further, that the Company may prior to the First Effective Time substitute therefor a single premium tail coverage with respect to D&O Insurance with an annual cost not in excess of three hundred percent (300%) of the last annual premium paid prior to the date of this Agreement.

The rights and obligations under this Section 7.5 shall survive consummation of the Offer and the Mergers and shall not be terminated or amended in a manner that is adverse to any Indemnified Party without the written consent of such Indemnified Party.

59

Board of Directors for purposes of causing any Takeover Statute to be applicable to the Offer, the Mergers, the Support Agreement or any of the other Transactions.

Section 7.7.           Obligations of Merger Subs.  Parent shall take all action necessary to cause each of the Merger Subs, the First Surviving Corporation and the Surviving Company to perform their respective obligations under this Agreement and to consummate the Transactions, including the Offer and the Mergers, upon the terms and subject to the conditions set forth in this Agreement.

Effective as of the First Effective Time and for a period of no less than two (2) years thereafter, Parent shall provide, or shall cause the Surviving Company to provide, to each employee of the Company and/or any Company Subsidiary who continues to be employed by the Parent or the Surviving Company or any Subsidiary thereof (the “Continuing Employees”), (i) cash compensation opportunities (including, without limitation, cash incentive compensation opportunities, but excluding any equity-based compensation), that are no less favorable in the aggregate than the cash compensation opportunities provided to such Continuing Employee as of immediately prior to the Acceptance Time, and (ii) employee benefits that are, in the aggregate, substantially comparable to those provided to such Continuing Employee as of immediately prior to the Acceptance Time. Effective as of the First Effective Time and thereafter, Parent shall provide, or shall cause the Surviving Company to provide, that periods of employment with the Company (including any current or former affiliate of the Company or any predecessor of the Company) shall, to the extent recognized under the corresponding Company Benefit Plan, be taken into account for all purposes under all employee benefit plans maintained by Parent or an affiliate of Parent for the benefit of the Continuing Employees, including vacation or other paid-time-off plans or arrangements, 401(k), pension or other retirement plans and any severance or health or welfare plans (other than for purposes of determining any accrued benefit under any defined benefit pension plan, eligibility for retirement under an equity-based compensation plan, eligibility for any retiree health plan or as would result in a duplication of benefits).

(b)           Effective as of the First Effective Time and thereafter, Parent shall, and shall cause the Surviving Company to, use commercially reasonable efforts to (i) ensure that no eligibility waiting periods, actively-at-work requirements or pre-existing condition limitations or exclusions shall apply with respect to the Continuing Employees under the applicable health and welfare benefits plan of Parent or any affiliate of Parent (except to the extent applicable under Company Benefit Plans immediately prior to the First Effective Time), (ii) waive any and all evidence of insurability requirements with respect to such Continuing Employees to the extent such evidence of insurability requirements were not applicable to the Continuing Employees under the Company Benefit Plans immediately prior to the First Effective Time, and (iii) credit each Continuing Employee with all deductible payments, out-of-pocket or other co-payments paid by such employee

60

under the Company Benefit Plans prior to the Closing Date during the year in which the Closing occurs for the purpose of determining the extent to which any such employee has satisfied his or her deductible and whether he or she has reached the out-of-pocket maximum under any corresponding health benefit plan of Parent or an affiliate of Parent for such year.  The Mergers shall not affect any Continuing Employee’s accrual of, or right to use, in accordance with Company policy as in effect immediately prior to the First Effective Time, any personal, sick, vacation or other paid-time-off accrued but unused by such Continuing Employee immediately prior to the First Effective Time.

(c)           If, at least ten (10) business days prior to the First Effective Time, Parent provides written notice to the Company directing the Company to terminate its 401(k) plan(s), the Company shall terminate any and all 401(k) plans effective as of the day immediately preceding the First Effective Time (the “401(k) Termination Date”).

(d)           Nothing in this Agreement shall confer upon any Continuing Employee any right to continue in the employ or service of Parent, the Surviving Company or any affiliate of Parent, or shall interfere with or restrict in any way the rights of Parent, the Surviving Company or any affiliate of Parent, which rights are hereby expressly reserved, to discharge or terminate the services of any Continuing Employee at any time for any reason whatsoever, with or without cause or shall prohibit Parent, the Surviving Company or any affiliate of Parent from amending or terminating any employee benefit plan (including any Company Benefit Plan) to the extent such amendment or termination is permitted by the terms of the applicable plan. Notwithstanding any provision in this Agreement to the contrary, nothing in this Section 7.8 shall (i) be deemed or construed to be an amendment or other modification of any Company Benefit Plan, employee benefit plan of any of the Merger Subs, or other employee benefit plan, or (ii) create any third party rights or remedies (including any right to compensation or benefits of any nature or kind whatsoever or any right under an employee benefit plan that such person would not otherwise have under the terms of that employee benefit plan without regard to this Agreement) in any current or former service provider of the Company or its affiliates (or any legal representatives, beneficiaries or dependents thereof).

Section 7.9.           Rule 16b-3.  Prior to the First Effective Time, the Company and Parent shall, as applicable, take all such steps as may be reasonably necessary or advisable hereto to cause any dispositions of Company equity securities (including derivative securities) and acquisitions of Parent equity securities pursuant to the Transactions contemplated by this Agreement by each individual who is a director or officer of the Company subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company to be exempt under Rule 16b-3 promulgated under the Exchange Act.

61

timely basis with respect to the status thereof.  The Company shall give Parent the opportunity to participate (at Parent’s expense) in the defense or settlement of any such litigation, and no such settlement shall be agreed to without the Parent’s prior written consent, which consent shall not be unreasonably withheld or delayed, except that Parent shall not be obligated to consent to any settlement which does not include a full release of Parent and its affiliates or which imposes an injunction or other equitable relief after the First Effective Time upon Parent or any of its affiliates. In the event of, and to the extent of, any conflict or overlap between the provisions of this Section 7.10 and Section 6.1 or Section 7.2, the provisions of this Section 7.10 shall control.

Section 7.11.         Delisting.  Each of the Parties agrees to cooperate with the other Parties in taking, or causing to be taken, all actions necessary to delist the Company Common Stock from the Nasdaq and terminate its registration under the Exchange Act, in each case, as promptly as practicable after the First Effective Time, provided that such delisting and termination shall not be effective until after the First Effective Time.

(c)           Each of the Parties acknowledges that the agreements contained in this Section 9.2 are an integral part of the Transactions and that the Termination Fee is not a penalty, but rather is liquidated damages in a reasonable amount that will compensate Parent and the Merger Subs in the circumstances in which the Termination Fee is payable for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Transactions. In addition, if the Company fails to pay in a timely manner any amount due pursuant to Section 9.2(b), then (i) the Company shall reimburse Parent for all costs and expenses (including disbursements and fees of counsel) incurred in the collection of such overdue amount, including in connection with any related claims, actions or proceedings commenced and (ii) the Company shall pay to Parent interest on the amount payable pursuant to Section 9.2(b) from and including the date payment of such amount was due to but excluding the date of actual payment at the prime rate set forth in The Wall Street Journal in effect on the date such payment was required to be made.  Notwithstanding anything to the contrary in this Agreement, if the Company Termination Fee is payable pursuant to this Section 9.2 and upon such payment pursuant to this Section 9.2, none of the Company, any of its Subsidiaries or any of their respective former, current or future officers, directors, partners, stockholders, managers, members, affiliates or agents shall have any further liability or obligation relating to or arising out of this Agreement or the Transactions.
