XI.  GENERAL PROVISIONS
     ------------------

     A. The parties hereby agree that this Agreement merely constitutes a

party without said other party's prior written consent.

     B. Any notice, request, demand, statement or other writing required or
permitted by this Agreement shall be deemed sufficiently given to or made upon

address of which the parties receive written notice.

     C. No failure or delay on the part of either party hereto in insisting upon
or enforcing or resorting to any of its powers, rights, remedies, or options
hereunder, and no partial or single exercise thereof, shall constitute a waiver
of any such powers, rights, remedies or options, unless such waiver be in
writing, signed by the party to be charged.

     D. If any provision of this Agreement should be held to be void or
unenforceable, in whole or in part, the court or tribunal so holding shall
reform the provision to make it enforceable while maintaining the spirit and
goal of the provision, and if the court or tribunal finds it cannot so reform
that provision, such provision or part thereof shall be treated as severable,
leaving valid the remainder of this Agreement.

     E. This Agreement, together with the Purchase and Sale Agreement to which
this Agreement is an Exhibit, including the Pledge and Security Agreement,
constitutes the entire understanding and agreement of the parties as to the
subject matter herein, and there are no representations, warranties, promises,
or undertakings other than those contained herein. As to the subject matter
hereof, this Agreement supersedes and cancels all previous agreements between

<PAGE>


the parties hereto. No course of conduct or dealing between the parties shall
act as a modification or waiver of any provision of this Agreement, and no
waiver or modification of any of the terms or provisions of this Agreement shall
be valid, unless contained in a single written document signed by both parties.

     F. This Agreement shall be binding upon the parties hereto and their
respective subsidiaries, affiliates, heirs, legal representatives, successors
and assigns.

     G. The headings in this Agreement are intended for convenience only, and
shall not be used to interpret the meaning of this Agreement or to determine the
rights of the parties.
