without limitation those set forth on Exhibit A attached hereto (collectively,

infringements of any of the rights included above, with the right, but not the
obligation, to sue for and collect such damages for said use or infringement of
the intellectual property rights identified above;

8. All licenses or other rights to use any of the Copyrights, Patents,
Trademarks, or Mask Works and all license fees and royalties arising from such
use to the extent permitted by such license or rights;

9. All amendments, extensions, renewals and extensions of any of the Copyrights,
Trademarks, Patents, or Mask Works; and

10. All proceeds and products of the foregoing, including without limitation all
payments under insurance or any indemnity or warranty payable in respect of any
of the foregoing.

This security interest is granted in conjunction with the security interest
granted to Bank under the Loan Agreement. The rights and remedies of Bank with
respect to the security interest granted hereby are in addition to those set
forth in the Loan Agreement and the other Loan Documents, and those which are
now or hereafter available to Bank as a matter of law or equity. Each right,
power and remedy of Bank provided for herein or in the Loan Agreement or any of
the Loan Documents, or now or hereafter existing at law or in equity shall be
cumulative and concurrent and shall be in addition to every right, power or
remedy provided for herein and the exercise by Bank of any one or more of the
rights, powers or remedies provided for in this Agreement, the Loan Agreement or
any of the other Loan Documents, or now or hereafter existing at law or in
