4.7Entire Agreement.  This Agreement, the Merger Agreement, and the documents referenced herein and therein, constitute the sole and entire agreement of the parties hereto with respect to the subject matter contained herein, and supersedes all prior and contemporaneous understandings, agreements, representations and warranties, both written and oral, with respect to such subject matter.

provision, in any other jurisdiction.  If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable.

4.10Rules of Construction.  It is the intention of the parties hereto that every covenant, term, and provision of this Agreement shall be construed simply according to its fair meaning and not strictly for or against any party (notwithstanding any rule of law requiring an agreement to be strictly construed against the drafting party), it being understood that the parties to this Agreement are sophisticated and have had adequate opportunity and means to retain counsel to represent their interests and to otherwise negotiate the provisions of this Agreement.  Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The section headings contained in this Agreement are inserted for convenience only and shall not be deemed to limit or otherwise affect in any way the meaning or interpretation of this Agreement.

Any purported assignment in violation of the foregoing shall be void.

4.12Specific Performance.  Each party hereto hereby acknowledges and agrees that the other parties would incur irreparable harm or injury for which money damages would not be an adequate remedy if for any reason a party fails to perform any of such party’s obligations under this Agreement in accordance with their specific terms.  Accordingly, each party agrees that the other parties (and, to the extent of its rights expressly provided pursuant to Section 4.5 and Section 4.6, the Company) shall be entitled, in seeking to enforce this Agreement against any the other parties hereto, to seek an injunction or injunctions, specific performance and other equitable relief to prevent breaches or threatened breaches of this Agreement by the other parties hereto and to enforce specifically the terms and provisions of this Agreement in the courts described in Section 4.3, without proof of damages or otherwise, this being in addition to any other remedy at law or in equity.  Each party hereto hereby waives any requirement for the posting of any bond or similar collateral in connection therewith and agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that the enforcing party (or, to the extent of its rights expressly provided pursuant to Section 4.5 and Section 4.6, the Company) has an adequate remedy at law or that an award of specific performance is not an appropriate remedy for any reason at law or equity.

4.13Stockholder Capacity.  Notwithstanding anything contained in this Agreement to the contrary, the representations, warranties, covenants and agreements made herein by each Stockholder are made solely with respect to such Stockholder and the Covered Shares.  Each Stockholder is entering into this Agreement solely in its capacity as the Beneficial Owner of such Covered Shares and nothing herein shall limit or affect any actions taken by any employee, officer or director of the Company (or Subsidiary of the Company) in his or her capacity as an employee, director or officer of the Company (or Subsidiary of the Company), including participating on behalf of, and in his or her capacity as an employee, director or officer of, the Company (or Subsidiary of the Company), including with respect to any discussions or negotiations with Parent

or with any third Person.  For the avoidance of doubt and notwithstanding anything to the contrary contained herein, nothing in this Agreement shall limit or restrict any Stockholder from voting in such Stockholder’s sole discretion on any matter other than the matters referred to in Section 2.1 hereof.  Nothing contained herein, and no action taken by any Stockholder pursuant hereto, shall be deemed to constitute the parties as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the parties are in any way acting in concert or as a group with respect to the obligations or the transactions contemplated by this Agreement.

4.14Action by the Company.  No waiver, consent, extension, amendment or other action by or on behalf of the Company pursuant to or as contemplated by this Agreement shall have any effect unless such waiver, consent, extension, amendment or other action is expressly approved by the Special Committee.

4.15Fees and Expenses.  Except as may otherwise be agreed in writing by the parties hereto, all costs and expenses (including all fees and disbursements of counsel, accountants, investment bankers, experts and consultants to a party) incurred in connection with this Agreement shall be paid by the party incurring such costs and expenses.

4.16Counterparts; Effectiveness.  This Agreement may be executed in one or more counterparts (including by facsimile or electronic (i.e., PDF) transmission), all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties hereto and delivered to the other parties hereto.
