The waiver by any party hereto of a breach of any provision hereunder shall not operate or be construed as a waiver of any prior or subsequent breach of the same or any other provision hereunder.

The words “hereof”, “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The words “date hereof” shall refer to the date of this Agreement. The term “or” is not exclusive. The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply “if”. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms. Any agreement or instrument defined or referred to herein or in any agreement or instrument that is referred to herein means such agreement or instrument as from time to time amended, modified or supplemented. The original parties hereto have participated jointly in the negotiation and drafting of this Agreement and, in the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as jointly drafted by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement. The parties each hereby acknowledge that this Agreement reflects an agreement between sophisticated parties derived from arm’s-length negotiations. Further, prior drafts of this Agreement or any ancillary agreements hereto or the fact that any clauses have been added, deleted or otherwise modified from any prior drafts of this Agreement or any ancillary agreements hereto shall not be used as an aide of construction or otherwise constitute evidence of the intent of the parties hereto; and no presumption or burden of proof shall arise favoring or disfavoring any party hereto by virtue of such prior drafts.

SECTION 4.05.    Severability. If any provision of this Agreement is invalid, illegal or unenforceable, that provision will, to the extent possible, be modified in such a manner as to be valid, legal and enforceable but so as to retain most nearly the intent of the parties as expressed herein, and if such a modification is not possible, that provision will be severed from this Agreement, and in either case the validity, legality and enforceability of the remaining provisions of this Agreement will not in any way be affected or impaired thereby. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only as broad as is enforceable.

SECTION 4.06.    Counterparts. This Agreement may be executed by the parties hereto in separate counterparts, each of which when so executed and delivered shall be an original, but all such counterparts shall together constitute one and the same instrument. Each counterpart may consist of a number of copies hereof each signed by less than all, but together signed by all of the parties hereto.

SECTION 4.07.    Entire Agreement; No Third-Party Beneficiaries; Several Obligations.

SECTION 4.08.    Governing Law. This Agreement and the rights and obligations of the parties hereto shall be governed by and construed in accordance with the Laws of the State of Delaware. The parties hereby irrevocably and unconditionally consents to submit to the exclusive jurisdiction of the Court of Chancery of the State of Delaware and of the federal

EACH PARTY TO THIS AGREEMENT IRREVOCABLY WAIVES THE RIGHT TO A TRIAL BY JURY IN CONNECTION WITH ANY MATTER ARISING OUT OF THIS AGREEMENT and, to the fullest extent permitted by Applicable Law, any defense or objection it may now or hereafter have to the laying of venue of any proceeding under this Agreement brought in the Delaware Courts and any claim that any proceeding under this Agreement brought in any such court has been brought in an inconvenient forum.

SECTION 4.09.    Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by operation of law or otherwise, by any of the parties without the prior written consent of the other parties hereto (and, in the case of the consent of the Company, the prior approval of the Board of Directors). Any purported assignment without such prior written consent shall be void. Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective successors and assigns.

SECTION 4.10.    Enforcement; Information. The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties will be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, without the necessity of proving the inadequacy of money damages as a remedy, this being in addition to any other remedy to which they are entitled at Law or in equity. Each Stockholder shall provide the Company with such information regarding the direct or indirect ownership of Shares and holding of Voting Power by such Stockholder, members of such Stockholder’s Family and their respective affiliates and any agreements (including hedging, pledge or derivative transaction agreements) relating to any Shares or Voting Power to which any of them may be a party, in each case as may be requested from time to time by the Company.

SECTION 4.11.    Effectiveness; Termination. This Agreement shall become effective as of the Effective Time. In the event that the Merger Agreement shall be terminated in accordance with its terms prior to the Effective Time, this Agreement shall thereupon terminate.

(ii)    which becomes available to the public other than as a result of a breach of Section 4.12(a);

(iii)    which is already in such Stockholder’s possession prior to disclosure by the Company, provided that, to such Stockholder’s knowledge, such information is not subject to another confidentiality agreement or other obligation of secrecy to the Company;

(iv)    which has been, is or becomes independently developed by such Stockholder or on its behalf without a breach of Section 4.12(a); or

(v)    which has been provided on a non-confidential basis to such Stockholder or any of its officers, employees, representatives, consultants or advisors by a third party who obtained such information other than from any such Person or other than as a result of a breach of Section 4.12(a); provided that, to such Stockholder’s knowledge, such other source is not bound by a confidentiality obligation to the Company.

SECTION 4.13.    Representations and Warranties. The Company represents and warrants to the Stockholders, and each of the Stockholders represents and warrants to the Company, that as of the date of this Agreement:

(b)    the execution and delivery by it of this Agreement and the consummation by it of the transactions contemplated by this Agreement have been duly authorized by all necessary corporate or limited liability company action on its part; and

- 11 -

terms, subject, as to enforceability, to bankruptcy, insolvency and other Laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

SECTION 4.14.    Acknowledgment of Securities Laws. Each Stockholder hereby acknowledges that it is aware, and that it will advise its representatives who are informed as to the material non-public information that is the subject of Section 4.12, that the United States securities Laws prohibit any Person who has received from an issuer material, non-public information from purchasing or selling securities of such issuer or from communication of such information to any other Person under circumstances in which it is reasonably foreseeable that such Person is likely to purchase or sell such securities.
