     SECTION 9. Miscellaneous.

     (a)  Severability.  If any term or other  provision  of this  Agreement  is
invalid,  illegal or incapable  of being  enforced by any rule of law, or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the  economic or legal  substance  of
the transactions  contemplated  herein are not affected in any manner materially
adverse  to any party  hereto.  Upon such  determination  that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall  negotiate  in good  faith to modify  this  Agreement  so as to effect the
original  intent of the parties as closely as possible in a mutually  acceptable
manner.

     (b) Binding Effect and  Assignment.  The provisions of this Agreement shall
be  binding  upon and  inure to the  benefit  of the  parties  hereto  and their
respective  successors  and  assigns;  no party to this  Agreement  may  assign,
delegate  or  otherwise  transfer  any of its rights or  obligations  under this
Agreement without the prior written consent of the other parties hereto.

     (c)  Amendments  and  Modification.  Except as may  otherwise  be  provided
herein,  any provision of this  Agreement may be amended,  modified or waived by
the parties  hereto if, and only if, such  amendment or waiver is in writing and
signed, in the case of an amendment, by the parties hereto, and in the case of a
waiver, by the party against whom the waiver is to be effective.

     (d) Specific Performance; Injunctive Relief. The parties hereto acknowledge
that  Hammond  shall be  irreparably  harmed and that there shall be no adequate
remedy at law for a  violation  of any of the  covenants  or  agreements  of the
Stockholders set forth herein.  Therefore, it is agreed that, in addition to any
other remedies that may be available to Hammond upon any such violation, Hammond
shall  have the right to enforce  such  covenants  and  agreements  by  specific
performance, injunctive relief or by any other means available to Hammond at law
or in equity without the necessity of proving the inadequacy of money damages as
a remedy.

business-to-business e-commerce market. More information about potential factors
that could affect the Company's  business and  financial  results is included in
