NOW, THEREFORE, in consideration of the foregoing and the premises herein contained, Assignor hereby agrees with Lender as follows: 1. To secure the complete and timely satisfaction of all obligations of Assignor under the Note (the "Obligations"), Assignor hereby grants, assigns and conveys to Lender all of its rights, title and interest, resulting from the Assignment to: a) all right, title and interest in and to the technology, patents, software, designs, models, drawings, know-how, trademarks, trade names, and service marks (including the goodwill associated with the trademarks, trade names and service marks), trade secrets, copyrights, registrations and applications therefor, relating to non-invasive means of diagnosing disease through the use of flourescence spectroscopy, including, without limitation, any and all books, records, computer tapes or disks, flow diagrams, specifications sheets, source codes, and object codes relating to the foregoing and other physical manifestations of the foregoing; and b) all right, title, interest, powers, privileges and options in and to, and in accordance with, that certain license agreement dated May 7, 1991, by and between GEORGIA TECH RESEARCH CORPORATION and Seller, including without limitation, all proceeds thereof (such as, by way of example, license royalties and proceeds of infringement suits), the right to sue for past, present and future infringements, and 12 all rights corresponding thereto (collectively called the "Assets"). 2. Assignor agrees that, until all of the Obligations shall have been satisfied in full, it will not enter into any agreement (for example, a license agreement) which is inconsistent with Assignor's obligations under this Agreement, without Lender's prior written consent. 3. Unless and until there shall have occurred and be continuing a breach of the Obligations, Lender hereby grants to Assignor the exclusive, non-transferable right, license, and use of and to the Assets, provided, however, Assignor agrees not to sell, assign, or otherwise encumber its interest in, or grant any sublicense under the Assets, or any part thereof, without the prior written consent of Lender. 4. If any breach of the Obligations shall have occurred and be continuing, Assignor's rights, license, and use of and to the Assets set forth in Section 3, shall terminate forthwith, and the Lender shall have, in addition to all other rights and remedies given it by this Agreement, those allowed by law and the rights and remedies of a secured party under the Uniform Commercial Code as enacted in any jurisdiction in which the Assets may be located and, without limiting the generality of the foregoing, the Lender may immediately, without demand or performance and without other notice (except as set forth next below) or demand whatsoever to Assignor, all of which are hereby expressly waived, and without advertisement, sell at public or private sale or otherwise realize upon, in Atlanta, Georgia, or elsewhere, the whole or from time to time any part of the Assets, or any interest which the Assignor may have therein, and after deducting from the proceeds of sale or other disposition of the Assets all expenses (including all reasonable expenses for brokers' fees and legal services), shall apply the residue of such proceeds toward the satisfaction of the obligations. Any remainder of the proceeds after satisfaction in full of the Obligations shall be paid over to the Assignor. Notice of any sale or other disposition of the Assets shall be given to Assignor at least five (5) days before the time of nay intended public or private sale or other disposition of the Patents is to be made, which Assignor hereby agrees shall be reasonable notice of such sale or other disposition. At any such sale or other disposition, any holder of the Note or Lender may, to the extent permissable under applicable law, purchase the whole or any part of the Assets sold, free from any right of redemption on the part of Assignor, which right is hereby waived and released. 5. If any breach of the Obligations shall have occurred and be continuing, Assignor hereby authorizes and empowers Lender to make, constitute and appoint any officer or agent of Lender, as Lender may select in its exclusive discretion, as Assignor's true and lawful attorney-in-fact, with the power to endorse Assignor's 2 13 name on all applications, documents, papers and instruments necessary for Lender to use the Assets, or any part thereof, or to grant or issue any exclusive or non-exclusive license under the Assets, or any part thereof, to any third person, or necessary for Lender to assign, pledge, convey or otherwise transfer title in or dispose of the Assets, or any part thereof, to any third person. Assignor hereby ratifies all that such attorney shall lawfully do or cause to be done by virtue hereof. This power of attorney is coupled with an interest and shall be irrevocable for the life of this Agreement. 6. At such time as Assignor shall completely satisfy all of the Obligations, this Agreement shall terminate and Lender shall execute and deliver to Assignor all deeds, assignments and other instruments as may be necessary or proper to re-vest in Assignor full title to the Assets, subject to any disposition thereof which may have been made by Lender pursuant hereto. 7. No course of dealing between Assignor and Lender, nor any failure to exercise, nor any delay in exercising, on the part of Lender, any right, power or privilege hereunder or under the Note shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder or thereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege. 8. All of Lender's rights and remedies with respect to the Assets, whether established hereby or by the Note, or by any other agreements or by law shall be cumulative and may be exercised singularly or concurrently. 9. The provisions of this Agreement are severable, and if any clause or provision shall be held invalid and unenforceable in whole or in part in any jurisdiction, then such invalidity or unenforceability shall affect only such clause or provision, or part thereof, in such jurisdiction, and shall not in any manner affect such clause or provision in any other jurisdiction, or any other clause or provision of this Agreement in any jurisdiction. 10. This Agreement is subject to modification only by a writing signed by the parties. 11. The benefits and burdens of this Agreement shall inure to the benefit of and be binding upon the respective successors and permitted assigns of the parties. 12. The validity and interpretation of this Agreement and the rights and obligations of the parties shall be governed by the laws of the State of Georgia. 3 14 WITNESS the execution hereof under seal as of the day and year first above written.
