into any other Sections of this Agreement.

     Section 11.03  Entire Agreement. This Agreement together with the documents
referred to in this Agreement constitutes a complete and exclusive statement of
the terms of the agreement between the Parties with respect to its subject
matter and supersedes all prior understandings, agreements, or representations

any manner to the subject matter hereof.

     Section 11.04  Counterparts and Facsimile Execution. This Agreement may be
executed in two or more counterparts, each of which shall be deemed an original,
but all of which together shall constitute one and the same instrument. Any
counterpart or other signature delivered via facsimile by any party shall be

Agreement by that party.

     Section 11.05  Section Headings, Construction. The headings of Sections in
this Agreement are provided for convenience only and will not affect its
construction or interpretation. All references to "Section" or "Sections" refer
to the corresponding Section or Sections of this Agreement. The Parties have

Agreement shall be construed as if drafted jointly by the Parties and no
presumption or burden of

                                       21

proof shall arise favoring or disfavoring any party by virtue of the authorship

Unless otherwise expressly provided, the word "including" does not limit the
preceding words or terms. The Parties intend that each representation, warranty,

mitigate the fact that the party is in breach of the first representation,
warranty, or covenant.

Agreement will be binding upon and inure to the benefit of the Parties and

provisions and conditions are for the sole and exclusive benefit of the Parties
to this Agreement and their successors and permitted assigns.

amendment. The rights and remedies of the Parties to this Agreement are
cumulative and not alternative. Neither the failure nor any delay by any party
in exercising any right, power, or privilege under this Agreement or the
documents referred to in this Agreement will operate as a waiver of such right,

or privilege will preclude any other or further exercise of such right, power,
or privilege or the exercise of any other right, power, or privilege. To the
maximum extent permitted by applicable law, (a) no claim or right arising out of
this Agreement or the documents referred to in this Agreement can be discharged

given by a party will be applicable except in the specific instance for which
and to the extent to which it is given; and (c) no notice to or demand on one

right of the party giving such notice or demand to take further action without
