          7. General. This First Amendment shall not be assigned by any party without the prior
written consent of the other party hereto. This First Amendment may not be amended except by a
written agreement executed by the party to be charged with the amendment. The Agreement, including
the Exhibits and Schedules thereto, as amended by this First Amendment, embodies the entire
agreement between the parties thereto with respect to the transactions contemplated therein and
supersedes all prior agreements between the parties with respect to its subject matter. This First
Amendment shall be governed by the internal laws of the State of Delaware, without regard to
conflict of law principles thereunder. This First Amendment may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which together shall constitute
but one and the same instrument. Signatures of the parties transmitted by facsimile shall be deemed
to be their original signatures for all purposes. The captions and headings used in this First
Amendment are inserted for convenience only and shall not be deemed to constitute part of this
First Amendment or to affect the construction or interpretation hereof.




          8. Severability. If any provision of this First Amendment is held to be illegal,
invalid or unenforceable under present or future laws effective during the term hereof, such
provision shall be fully severable and this First Amendment shall be construed and enforced as if
such illegal, invalid or unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be affected by the illegal,
invalid or unenforceable provision or by its severance herefrom. Furthermore, in lieu of such
illegal, invalid or unenforceable provision, there shall be added automatically as part of this
First Amendment a provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.




          9. Interpretation. Unless specifically stated otherwise, references to Sections,
Exhibits and Schedules refer to Sections, Exhibits and Schedules in the Agreement, as amended by
this First Amendment. References to “includes” and “including” mean “includes without limitation”
and “including without limitation.” No provision of this First Amendment shall be interpreted in
favor of, or against, any party by reason of the extent to which either such party or its counsel
participated in the drafting thereof or by reason of the extent to which any such provision is
inconsistent with any prior draft hereof or thereof.




          10. Full Force and Effect of Agreement. All rights, duties and obligations of the
parties are and shall continue to be governed by and in accordance with the Agreement, including
without limitation the performance and consummation of the transactions as contemplated therein,
except as specifically set forth in this First Amendment.
