            4.4 HEADINGS. The headings contained in this Agreement are for
reference purposes only and shall not affect in any way the meaning or

and understanding and, except as set forth herein, supersedes all prior
agreements and understandings of the parties with respect to the matters
contemplated hereby.

            4.7 AFFILIATES. The parties hereto acknowledge that they conduct
their business operations through Subsidiaries and/or Affiliates. The parties
hereto therefore agree that they will cause their respective Subsidiaries and
controlled Affiliates to abide by the terms of this Agreement as if they were

Agreement. Further, each party shall be entitled to cause its obligations
hereunder to be satisfied, and to cause its benefits and rights hereunder to be

            4.9 CHOICE OF LAW. This Agreement shall be interpreted and construed
in accordance with the internal laws (and not the conflicts of laws rules) of
the State of Delaware applicable to contracts made and to be performed in the
State of Delaware.

            4.10 ASSIGNMENT. This Agreement shall be binding upon and inure to
the benefit of the successors of the parties but shall not be assignable without

written approval of the Audit Committee), respectively.

            4.11 SEVERABILITY. If any provision of this Agreement is prohibited
by or held to be invalid under applicable law, such provision will be
ineffective to the extent of such prohibition or invalidity, without
invalidating the remaining provisions of this Agreement. Each provision in this
Agreement shall be read and construed independently of the other provisions
hereof. If any provision of this Agreement, as applied to any party or to any
circumstances, is adjudged by a court to be invalid or unenforceable for any
reason, such judgment shall in no way affect any other provision of this
Agreement, the application of such provision in any other circumstances or to
any other party or the validity or enforceability of this Agreement. If any
provision or part of a provision in this Agreement is held to be unenforceable
because of the duration of such provision, the geographical area covered by such
provision or the range of activities covered by such provision, the parties
agree that the court making such determination will have the power to reduce the
duration, area and scope of such provisions and to delete specific words or
phrases, if and as necessary under law, and in its reduced form such provision
will then be enforceable and will be enforced.
