RIGHTS AND REMEDIES Upon the occurrence of any such Event of Default and during the continuance thereof, in addition to all other rights and remedies of Secured Party, whether provided under law, the Financing Agreements or otherwise, Secured Party shall have the following rights and remedies which may be exercised without notice to, or consent by, Debtor except as such notice or consent is expressly provided for hereunder: (a) Secured Party may require that neither Debtor nor any affiliate or subsidiary of Debtor make any use of the Patents for any purpose whatsoever. Secured Party may make use of any Patents for the sale of goods, completion of work-in-process or rendering of services or otherwise in connection with enforcing any other security interest granted to Secured Party by Debtor or any subsidiary or affiliate of Debtor. (b) Secured Party may grant such license or licenses relating to the Collateral for such term or terms, on such conditions, and in such manner, as Secured Party shall in its discretion deem appropriate. Such license or licenses may be general, special, or otherwise, and may be granted on an exclusive or non-exclusive basis throughout all or any part of the United States of America, its territories and possessions, and all foreign countries. (c) Secured Party may assign, sell, or otherwise dispose of the Collateral or any part thereof, either with or without special conditions or stipulations except that if notice to Debtor of intended disposition of Collateral is required by law, the giving of five (5) business days prior notice in the manner set forth in subparagraph 6(b) hereof shall be deemed reasonable notice thereof and Debtor waives any other notice with respect thereto. Secured Party shall have the power to buy the Collateral or any part thereof, and Secured Party shall also have the power to execute assurances and perform all other acts which Secured Party may, in its discretion, deem appropriate or proper to complete such assignment, sale, or disposition. (d) In addition to the foregoing, in order to implement the assignment, sale, or other disposition of any of the Collateral pursuant to Subparagraph 5(c) hereof, Secured Party may at any time execute and deliver on behalf of Debtor, pursuant to the authority granted in the Powers of Attorney described in Subparagraph 3(f) hereof, one or more instruments of assignment of the Patents (or any application, registration, or recording relating thereto), in form suitable for filing, recording, or registration. Debtor agrees to pay Secured Party on demand all costs incurred in any such transfer of the Collateral, including, but not limited to, any taxes, fees, and reasonable attorneys' fees and legal expenses. (e) Secured Party may first apply the proceeds actually received from any such license, assignment, sale, or other disposition of Collateral to the costs and expenses thereof, including, without limitation, attorneys' fees and all legal, travel, and other expenses which may be incurred by Secured Party. Thereafter, Secured Party may apply any remaining proceeds to such of the Obligations as Secured Party may in its discretion determine. Debtor shall remain liable to Secured Party for any expenses or obligations remaining unpaid after the application of such proceeds, and Debtor will pay Secured Party on demand any such unpaid amount, together with interest at a rate equal to the highest rate then payable on the Obligations. -5- (f) Debtor shall supply to Secured Party or to Secured Party's designee, Debtor's knowledge and expertise relating to the manufacture and sale of the products and services to which the Patents relate and Debtor's customer lists and other records relating to the Patents and the distribution thereof.
