The Stockholder shall promptly (but in any event within one business day) advise Parent of any Acquisition Proposal or Product Transaction Proposal received by the Stockholder or any of his Affiliates, the material terms and conditions of any such Acquisition Proposal or Product Transaction Proposal (including any material changes thereto) and the identity of the Person making any such Acquisition Proposal or Product Transaction Proposal.

SECTION 5.     Non-Solicitation.

(a)            From and after the date of this Agreement, except as otherwise permitted pursuant to the Merger Agreement, the Stockholder agrees that he and his Affiliates (for purposes of this Agreement, the Company shall not be deemed to be an Affiliate of the Stockholder) shall not, and shall cause his or their Representatives not to, directly or indirectly engage in any conduct prohibited by Section 5.3 of the Merger Agreement.

(e)            Applicable Legal Requirements; Jurisdiction; Specific Performance; Remedies.

10

(i)            This Agreement and any disputes arising from or relating to this Agreement (whether based in contract, tort, or otherwise) shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof. In any action or proceeding arising out of or relating to this Agreement: (A) each of the parties hereto irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware and any state appellate court therefrom or, if (but only if) such court lacks subject matter jurisdiction, the United States District Court sitting in New Castle County in the State of Delaware and any appellate court therefrom (collectively, the “Delaware Courts”); and (B) each of the parties hereto irrevocably consents to service of process by first class certified mail, return receipt requested, postage prepaid, to the address at which such party is to receive notice in accordance with Section 11(a). Each of the parties hereto irrevocably and unconditionally (1) agrees not to commence any such action or proceeding except in the Delaware Courts, (2) agrees that any claim in respect of any such action or proceeding may be heard and determined in the Delaware Courts, (3) waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the jurisdiction or laying of venue of any such action or proceeding in the Delaware Courts and (4) waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in the Delaware Courts. The parties hereto agree that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Legal Requirements; provided, however, that nothing in the foregoing shall restrict any party’s rights to seek any post-judgment relief regarding, or any appeal from, such final trial court judgment.

(ii)            The parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the parties hereto do not perform their obligations under the provisions of this Agreement in accordance with its specified terms or otherwise breach such provisions. The parties acknowledge and agree that (A) the parties shall be entitled to an injunction or injunctions, specific performance, or other equitable relief, to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in the courts described in this Section 11(e) without proof of damages or otherwise, this being in addition to any other remedy to which they are entitled under this Agreement and (B) the right of specific performance is an integral part of the transactions contemplated by this Agreement and without that right, the parties hereto would not have entered into this Agreement. Each of the parties hereto agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that the other party or parties hereto have an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity. The parties hereto acknowledge and agree that any party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 11(e) shall not be required to provide any bond or other security in connection with any such order or injunction.

(iii)            EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING BETWEEN THE PARTIES HERETO ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

(f)            Assignment. This Agreement shall be binding upon, and shall be enforceable by and inure solely to the benefit of, the parties hereto and their respective successors and permitted assigns; provided, however, that neither this Agreement nor any of the rights hereunder may be assigned without the prior written consent of the other parties hereto, and any attempted assignment of this Agreement or any of such rights without such consent shall be void and of no effect; provided, further, however, that Parent or Purchaser may assign its rights under this Agreement to any one or more Affiliates at any time so long as Parent provides the other parties hereto with prior written notice of such assignment; provided that no such assignment shall relieve Parent of its obligations hereunder.

(g)            Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If a final judgment of a court of competent jurisdiction declares that any term or provision of this Agreement is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit such term or provision, to delete specific words or phrases or to replace such term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be valid and enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term or provision.

(h)            Amendment. Subject to applicable Legal Requirement and except as otherwise provided in this Agreement, this Agreement may be amended, modified and supplemented by written agreement of the parties hereto. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

For purposes of this Agreement, the parties agree that: (i) whenever the context requires, the singular number shall include the plural, and vice versa; (ii) the masculine gender shall include the feminine and neuter genders; the feminine gender shall include the masculine and neuter genders; and the neuter gender shall include masculine and feminine genders; (iii) the word “extent” in the phrase “to the extent” means the degree to which a subject or other thing extends, and does not simply mean “if’; (iv) the words “include” and “including,” and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words “without limitation;” (v) the meaning assigned to each capitalized term defined and used in this Agreement is equally applicable to both the singular and the plural forms of such term, and words denoting any gender include all genders; (vi) where a word or phrase is defined in this Agreement, each of its other grammatical forms has a corresponding meaning unless the context otherwise requires; (vii) a reference to any specific Legal Requirement or to any provision of any Legal Requirement includes any amendment to, and any modification, re-enactment or successor thereof, any legislative provision substituted therefor and all rules, regulations and statutory instruments issued thereunder or pursuant thereto, except that, for purposes of any representations and warranties in this Agreement that are made as a specific date, references to any specific Legal Requirement will be deemed to refer to such legislation or provision (and all rules, regulations and statutory instruments issued thereunder or pursuant thereto) as of such date; (viii) references to any agreement or Contract are to that agreement or Contract as amended, modified or supplemented as of the date hereof or, thereafter from time to time; (ix) they have been represented by legal counsel during the negotiation and execution and delivery of this Agreement and therefore waive the application of any Legal Requirement, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document; and (x) the word “or” shall not be exclusive (i.e., “or” shall be deemed to mean “and/or”).

Notwithstanding anything herein to the contrary, nothing herein shall in any way restrict a director or officer of the Company in the reasonable exercise of his or her fiduciary duties as a director or officer of the Company or in his or her capacity as a trustee or fiduciary of any employee benefit plan or trust or prevent or be construed to create any obligation on the part of any director or officer of the Company or any trustee or fiduciary of any employee benefit plan or trust from taking any action in his or her capacity as such director, officer, trustee or fiduciary.
