AGREEMENTS

In consideration of the recitals and the representations, warranties, covenants and agreements contained herein, and intending to be legally bound hereby, the parties hereto agree as follows:

1.1 Tender Agreements.

(a) Agreement to Tender Shares in Offer. Unless this Agreement shall have been terminated pursuant to the terms hereof or the Offer is terminated in accordance with the terms of the Merger Agreement, the Stockholder hereby agrees that such Stockholder shall validly tender (and deliver any certificates evidencing, or an appropriate affidavit of lost certificate with respect thereto, to

the extent such certificates have been lost, misplaced or destroyed) its Shares held in record name, or direct the broker or such other Person that is the holder of record of any Shares held beneficially by the Stockholder to validly tender such Shares, into the Offer promptly following, and in any event no later than fifteen (15) business days after commencement (within the meaning of Rule 14d-2 under the Exchange Act) of the Offer (or if the Stockholder has not received the Offer Documents by such time, within four (4) business days following receipt of such documents) and no later than five (5) business days after such Stockholder acquires beneficial ownership of any additional Shares in accordance with the procedures set forth in the Offer Documents, free and clear of all Liens.

(b) Termination of Offer. If the Offer is terminated or withdrawn by Merger Sub, or the Merger Agreement is terminated prior to the purchase of Shares in the Offer, Parent and Merger Sub shall promptly and in any event no later than three (3) business days return, and shall cause any depository or paying agent, acting on behalf of Parent and Merger Sub, to promptly and in any event no later than three (3) business days return all tendered Shares to the Stockholder.

(c) Agreement Not to Tender Shares in Competing Offer. At all times commencing with the execution and delivery of this Agreement and continuing until this Agreement shall have been terminated pursuant to the terms hereof, Stockholder shall not tender the Shares into any tender or exchange offer commenced by a Person other than Parent, Merger Sub or any other Subsidiary of Parent.

(b) At any meeting of stockholders of the Company, the Stockholder shall vote (or cause to be voted) all of the Shares: (i) against any inquiry, proposal, offer, indication of interest or transaction that constitutes or could reasonably be expected to lead to, an Acquisition Proposal or Acquisition Transaction relating to the Company and (ii) against any action, proposal, transaction or agreement which would reasonably be expected to impede, interfere with, delay, discourage, adversely affect or inhibit the timely consummation of the Offer or the Merger or the fulfillment of Parent’s, the Company’s, or Merger Sub’s conditions under the Merger Agreement or change in any manner the voting rights of any security of the Company (including by any amendments to the Company’s charter or bylaws). Except as set forth in clauses (i) and (ii) of this Section 1.2(b) or clause (A) of Section 1.3, Stockholder shall not be restricted from voting in favor of, against or abstaining with respect to any other matters presented to the stockholders of the Company.

None of the information relating to the Stockholder provided by or on behalf of the Stockholder in writing for inclusion in the Offer Documents will, at the respective times that the Offer Documents are filed with the SEC or are first mailed to the holders of the Company Common Stock, contain any untrue statement of material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

The failure of the spouse, if any, of any Stockholder that is an individual, to be a party or signatory to this Agreement shall not (A) prevent the Stockholder from performing the Stockholder’s obligations contemplated hereunder or (B) prevent this Agreement from constituting the legal, valid and binding obligation of the Stockholder in accordance with its terms.

(d) (i) Other than filings required by the SEC or the New York Stock Exchange, no filing with, and no permit, authorization, consent or approval of any state, federal or foreign governmental authority is necessary on the part of the Stockholder for the execution and delivery of this Agreement by the Stockholder and the performance by the Stockholder of the Stockholder’s obligations under this Agreement and (ii) neither the execution and delivery of this Agreement by the Stockholder nor the performance by the Stockholder of the Stockholder’s obligations under this Agreement nor compliance by the Stockholder with any of the provisions hereof shall (A) result in the creation of an encumbrance on any of the Shares or (B) violate any order, writ, injunction, decree, statute, rule or regulation applicable to the Stockholder or any of the Shares, except in the case of (A) or (B) for restrictions on transfer under the Securities Act of 1933, as amended or violations, breaches or defaults that would not in the aggregate materially impair the ability of the Stockholder to perform its obligations hereunder.

(e) As of the date hereof, there is no Action pending or, to the knowledge of the Stockholder, threatened against or affecting the Stockholder and/or any of its Affiliates before or by any Governmental Authority that would reasonably be expected to impair the ability of the Stockholder to perform its obligations hereunder or to consummate the transactions contemplated hereby in a timely manner.

1.9 Parent. Nothing herein shall be construed to limit or affect any action or inaction by (i) Parent or Merger Sub in accordance with the terms of the Merger Agreement or (ii) any Affiliate, officer, director or direct or indirect equity holder of Parent or Merger Sub acting in his or her capacity as a director or officer of Parent or Merger Sub; provided, however, that this Section 1.11 shall not relieve any such Person from any liability or obligation that he, she or it may have independently of this Agreement or as a consequence of any action or inaction by such Person.

No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any

other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by applicable law.

(d) When a reference is made in this Agreement to a Section, such reference shall be to a Section of this Agreement unless otherwise indicated. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Wherever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.”
