        5.8.    Governing Law; Consent to Jurisdiction; Waiver of Jury Trial.    

        (a)   This Agreement shall be governed by and construed in accordance with the laws of the State of Maryland without giving effect to the principles of conflicts of law. Each party irrevocably submits to the jurisdiction of (i) any Maryland State court, and (ii) any Federal court of the United States sitting in the State of Maryland, solely for the purposes of any suit, action or other proceeding between any of the parties hereto arising out of this Agreement or any transaction contemplated hereby. Each party agrees to commence any suit, action or proceeding relating hereto either in any Federal court of the United States sitting in the State of Maryland or, if such suit, action or other proceeding may not be brought in such court for reasons of subject matter jurisdiction, in any Maryland State court. Each party irrevocably and unconditionally waives any objection to the laying of venue of any suit, action or proceeding between any of the parties hereto arising out of this Agreement or any transaction contemplated hereby in (i) any Maryland State court, and (ii) any Federal court of the United States sitting in the State of Maryland, and hereby

5

further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. Each party further irrevocably consents to the service of process out of any of the aforementioned courts in any such suit, action or other proceeding by the mailing of copies thereof by registered mail to such party at its address set forth in this Agreement, such service of process to be effective upon acknowledgment of receipt of such registered mail; provided that nothing in this Section 5.8 shall affect the right of any party to serve legal process in any other manner permitted by law. The consent to jurisdiction set forth in this Section 5.8 shall not constitute a general consent to service of process in the State of Maryland and shall have no effect for any purpose except as provided in this Section 5.8. The parties agree that a final judgment in any such suit, 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 law.

        (b)   Each of the parties irrevocably and unconditionally waives, to the fullest extent permitted by applicable law, any and all rights to trial by jury in connection with any suit, action or other proceeding between any of the parties hereto arising out of this Agreement or any transaction contemplated hereby.

        5.9.    Amendment; Waiver.    This Agreement may not be amended except by an instrument in writing signed by Parent and, to the extent such amendment relates to a Stockholder, such Stockholder. Each party may waive any right of such party hereunder by an instrument in writing signed by such party and delivered to Parent and the applicable Stockholder(s).

        5.10.    Remedies.    (a) Each party hereto acknowledges that monetary damages would not be an adequate remedy in the event that any covenant or agreement in this Agreement is not performed in accordance with its terms, and it is therefore agreed that, in addition to and without limiting any other remedy or right it may have, the non-breaching party will have the right to an injunction, temporary restraining order or other equitable relief in any court of competent jurisdiction enjoining any such breach and enforcing specifically the terms and provisions hereof. Each party hereto agrees not to oppose the granting of such relief in the event a court determines that such a breach has occurred, and to waive any requirement for the securing or posting of any bond in connection with such remedy.

        (b)   All rights, powers and remedies provided under this Agreement or otherwise available in respect hereof at law or in equity shall be cumulative and not alternative, and the exercise or beginning of the exercise of any thereof by any party shall not preclude the simultaneous or later exercise of any other such right, power or remedy by such party.

        5.11.    Severability.    Any term or provision of this Agreement which is determined by a court of competent jurisdiction to be invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction, and if any provision of this Agreement is determined to be so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable, in all cases so long as neither the economic nor legal substance of the transactions contemplated hereby is affected in any manner materially adverse to any party or its stockholders. Upon any such determination, the parties shall negotiate in good faith in an effort to agree upon a suitable and equitable substitute provision to effect the original intent of the parties.

        5.12.    Successors and Assigns; Third Party Beneficiaries.    Neither this Agreement nor any of the rights or obligations of any party under this Agreement shall be assigned, in whole or in part (by operation of law or otherwise), by any party without the prior written consent of Parent and the Stockholders, except that, without such prior written consent, Parent and/or Merger Sub may assign this Agreement (in whole or in part) to any Person to which it assigns any of its rights or obligations under

6

the Merger Agreement. Subject to the foregoing, this Agreement shall bind and inure to the benefit of and be enforceable by the parties hereto and their respective successors and permitted assigns. Nothing in this Agreement, express or implied, is intended to confer on any Person other than the parties hereto or their respective successors and permitted assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement.
