or other agreements of any kind whatsoever as a condition, precedent or

Agreement or the subject matter hereof. Any waiver of any breach of any terms or
conditions of this Agreement shall not operate as a waiver of any other breach
of such terms or conditions or any other term or condition, nor shall any
failure to enforce any provision hereof on any one occasion operate as a waiver
of such provision or of any provision hereof or a waiver of the right to enforce
such provision on any subsequent occasion. This Agreement may not be amended,
nor shall any waiver, change, modification, consent or discharge be effected,
except by an instrument in writing executed by or on behalf of the party against

discharge is sought. If any provision of this Agreement shall be held or deemed
to be, or shall in fact be, invalid, inoperative, or unenforceable as applied to
any particular case in any jurisdiction or jurisdictions, or in all
jurisdictions or in all cases, because of the conflict of any provision with any
constitution or statute or rule of public policy or for any other reason, such
circumstance shall not have the effect of rendering the provision or provisions
in question invalid, inoperative, or unenforceable in any jurisdiction or in any
<PAGE>

other case or circumstance or of rendering any other provision or provisions
herein contained invalid, inoperative or unenforceable to the extent that such
other provisions are not themselves actually in conflict with such constitution,
statute or rule of public policy, but this Agreement shall be reformed and
construed in any such jurisdiction or case as if such invalid, inoperative or
unenforceable provision had never been contained herein, and such provision
reformed so that it would be valid, operative and enforceable to the maximum
extent permitted in such jurisdiction or in such case. This Agreement shall be
governed by and construed and enforced in accordance with the laws of the State
of New York. Any notices required or permitted by this Agreement shall be in
writing and personally delivered or mailed by certified or registered mail,
return receipt requested, addressed to the parties at their addresses set forth
above, or to such other addresses as one party may specify to the other party,
from time to time, in writing.

      IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date and year first above written.
