Party to this Agreement, and this Agreement has been assigned to such an
Affiliate, this Agreement shall be assigned back to the party within 6 months
of the effective date of the change of Control.

                  (c) This Agreement shall be binding upon and inure solely

International Sale of Goods. The parties hereto hereby (a) submit to the
exclusive jurisdiction of any court of competent jurisdiction sitting in the
State of Delaware, the City of Wilmington for the purpose of any Action
arising out of or relating to this Agreement brought by any party hereto, and
(b) agree, to the fullest extent permitted by applicable law, to waive, and
not to assert by way of motion, defense, or otherwise, in any such Action,

venue of the Action is improper, or that this Agreement may not be enforced
in or by any of the above-named courts.

extent permissible, and the other provisions of this Agreement will remain in
force.

denial of or delays in processing of export license applications, fire,

courier, return receipt requested, to the address shown below or as may
otherwise be specified by either Party to the other in accordance with this
section.

         15.8. INDEPENDENT CONTRACTORS. The Parties to this Agreement are
independent contractors. There is no relationship of partnership, joint
venture, employment, franchise, or agency between the Parties. Neither Party
will have the power to bind the other or incur obligations on the other's
behalf without the other's prior written consent.

         15.9. WAIVER. No failure of either Party to exercise or enforce any
of its rights under this Agreement will act as a waiver of such rights.

complete and exclusive agreement between the parties with respect to the
subject matter hereof, superseding and replacing any and all prior
agreements, communications, and understandings (both written and oral)

rights under it waived, by a written document executed by both Parties.

                  15.11 THIRD PARTY LICENSE. Each party is relieved of its
obligations, if any, to (i) deliver the Source Code of a product licensed
hereunder or (ii) authorize the creation of Derivative Works or corrections
from Source Code hereunder to the extent that fulfilling such obligations
would cause such party to breach any third party license agreement entered
into by such party after the Effective Date.

Manager who will be responsible for establishing mutually agreeable pricing
policies, marketing plans and trademarks usage, support request procedures
