(d)                                 Entire Agreement.  This Agreement and, solely to the extent of the defined terms referenced herein, the LP Merger Agreement, embody the complete agreement and understanding among the parties hereto with respect to the subject matter hereof and supersede and preempt any prior understandings, agreements or representations by or among the parties, written and oral, that may have related to the subject matter hereof in any way.

(e)                                  Governing Law; Jurisdiction; Waiver of Jury Trial.  To the maximum extent permitted by applicable Law, the provisions of this Agreement shall be governed by and construed and enforced in accordance with the laws of the State of Delaware, without regard to principles of conflicts of law.  Each of the parties hereto agrees that this Agreement involves at least $100,000 and that this Agreement has been entered into in express reliance upon 6 Del. C. § 2708.  Each of the parties hereto irrevocably and unconditionally confirms and agrees that it is and shall continue to be (a) subject to the jurisdiction of the courts of the State of Delaware and of the federal courts sitting in the State of Delaware, and (b) subject to service of process in the State of Delaware.  EACH PARTY HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY (I) CONSENTS AND SUBMITS TO THE EXCLUSIVE JURISDICTION OF ANY FEDERAL OR STATE COURT LOCATED IN THE STATE OF DELAWARE, INCLUDING THE DELAWARE COURT OF CHANCERY IN AND FOR NEW CASTLE COUNTY (THE “DELAWARE COURTS”) FOR ANY ACTIONS, SUITS OR PROCEEDINGS ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT (AND AGREES NOT TO COMMENCE ANY LITIGATION RELATING THERETO EXCEPT IN SUCH COURTS), (II) WAIVES ANY OBJECTION TO THE LAYING OF VENUE OF ANY SUCH LITIGATION IN THE DELAWARE COURTS AND AGREES NOT TO PLEAD OR CLAIM IN ANY DELAWARE COURT THAT SUCH LITIGATION BROUGHT THEREIN HAS BEEN BROUGHT IN ANY INCONVENIENT FORUM, (III) WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT AND (IV) AGREES THAT SERVICE OF PROCESS UPON SUCH PARTY IN ANY SUCH ACTION OR PROCEEDING SHALL BE EFFECTIVE IF SUCH PROCESS IS GIVEN AS A NOTICE IN ACCORDANCE WITH SECTION 7.2 OR IN ANY MANNER PRESCRIBED BY THE LAWS OF THE STATE OF DELAWARE.

(f)                                   Amendment; Waiver.  This Agreement may not be amended except by an instrument in writing signed by each party hereto.  Each party may waive any right of such party hereunder by an instrument in writing signed by such party and delivered to the other parties hereto.

(h)                                 Severability.  If any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any rule of applicable Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated by this Agreement are not affected in any manner materially adverse to any party hereto.  Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement are consummated as originally contemplated to the fullest extent possible.
