From the effective date of this Amendment, each patent application related to PATENT RIGHTS, i.e. original provisional or regular patent applications, divisionals, continuations, or continuations-in-part, shall be filed by INHIBITEX in the name of SYSTEM using counsel acceptable to SYSTEM. Prior to filing such applications, INHIBITEX shall determine the scope of such applications in consultation with SYSTEM. INHIBITEX agrees to INDEMNIFY and HOLD SYSTEM HARMLESS for the legal fees and expenses INHIBITEX incurs in prosecuting and maintaining PATENT RIGHTS. In the event the Attorney General of Texas (the "AG") rules that counsel pursuing patent protection for SYSTEM must be approved by the AG, INHIBITEX agrees to take all necessary steps to assure compliance with the AG's ruling including, if necessary, modifying this Agreement to allow SYSTEM to hire patent counsel. Prior to filing a patent application related to PATENT RIGHTS, INHIBITEX agrees to provide SYSTEM with the curriculum vitae for each attorney INHIBITEX proposes to use to seek patent protection along with a letter from the firm the attorneys are associated with acknowledging that the firm will look solely to INHIBITEX for the payment of its fees and expenses. Unless exigent circumstances dictate to the contrary, INHIBITEX shall allow SYSTEM at least 30 days to approve of the attorneys INHIBITEX desires to hire to pursue PATENT RIGHTS. INHIBITEX shall also prosecute to completion the U.S. Patent Applications identified in and comprising PATENT RIGHTS. "Prosecution to completion" shall mean prosecution of the original and any continuing or divisional applications to issuance or to a final rejection. INHIBITEX is not required to, but may with the consent of SYSTEM, pursue an appeal to the Board of Patent Appeals and Interferences, or the Federal Circuit Courts, or similar action in foreign countries. Furthermore, INHIBITEX shall maintain any U.S. patent(s) resulting from the prosecution described hereinabove. In the event that INHIBITEX determines not to continue prosecution to completion or maintenance of U.S. Patent Applications comprising PATENT RIGHTS, INHIBITEX will inform SYSTEM of its decision in sufficient time for SYSTEM to make decisions regarding its desire to continue prosecution. In such case, SYSTEM shall have the right to continue the prosecution or maintenance at its own expense. However, any such applications or patents funded by SYSTEM thereafter shall be excluded from PATENT RIGHTS. 9. DELETE paragraph 5.02 in its entirety. 10. ADD a new paragraph 5.02 as follows: 5.02 Foreign Patent Applications. With the cooperation of SYSTEM, INHIBITEX shall file and prosecute, in the name of SYSTEM, foreign patent applications corresponding to U.S. patent applications filed pursuant to paragraph 5.01. (a) Election not to file. INHIBITEX will inform SYSTEM no less than three (3) months before all foreign filing deadlines [including the one year anniversary of each application filed in the U.S., as well as the national stage filing deadline of each application filed through the Patent Cooperation Treaty (PCT)] as to its selection of foreign countries in which it will seek corresponding patent protection. SYSTEM shall then have the Page 3 of 5 right to file corresponding foreign patent applications at its own expense in those foreign countries not selected by INHIBITEX. However, such applications funded at SYSTEM's expense shall be excluded from PATENT RIGHTS. (b) Prosecution and Maintenance of Foreign Patents. Should INHIBITEX file corresponding foreign patent application(s) and subsequently elects not to continue to prosecute and maintain such foreign patent(s) or patent application(s), it shall so notify the SYSTEM at least three (3) months prior to taking (or not taking) any action which would result in abandonment, withdrawal or lapse of such foreign patent(s) or application(s). SYSTEM shall then have the right to continue maintenance of prosecution of such foreign patent(s) or application(s) at its own expense. However, expenses incurred prior to the point of INHIBITEX taking (or not taking) such action shall remain the responsibility of INHIBITEX and such foreign patent(s) or application(s) shall be excluded from PATENT RIGHTS. 11. DELETE paragraph 5.03 in its entirety. 12. ADD a new paragraph 5.03 as follows: 5.03 Financial Responsibility. INHIBITEX, within thirty (30) days of receipt of a supporting invoice from SYSTEM, shall reimburse SYSTEM for all reasonable expenses incurred prior to the effective date of this Amendment by SYSTEM in filing, prosecuting, and maintaining the U.S. Patent Application(s) and patent(s) under the PATENT RIGHTS, in accordance with paragraph 5.01 hereinabove. Notwithstanding, INHIBITEX shall reimburse SYSTEM for reasonable expenses incurred prior to and henceforth by SYSTEM for legal services comprising the monitoring of the progress of INHIBITEX in filing, prosecuting, and maintaining the U.S. and foreign patent applications and patents under the PATENT RIGHTS. As of the effective date of this Amendment, INHIBITEX shall directly assume one hundred percent (100%) of the expenses it incurs and one hundred percent (100%) of the reasonable expenses incurred by SYSTEM related to filing, prosecution and maintenance of all U.S. and foreign patent application(s) and patent(s) as described in paragraph 5.01 and 5.02. Reasonable expenses incurred by SYSTEM shall not include (1) any substantive analysis of the prosecution of patents, (2) expenses associated with duplication of effort by multiple lawyers in monitoring the progress of the prosecution, and (3) legal fees for services other than the monitoring of the progress of the prosecution. 13. DELETE paragraph 5.04 in its entirety. 14. ADD a new paragraph 5.04 as follows: 5.04 Information. INHIBITEX shall keep SYSTEM promptly and fully informed of the course of patent prosecution or other proceedings related to the protection of PATENT RIGHTS. INHIBITEX shall cooperate with SYSTEM to allow SYSTEM the timely and reasonable opportunity to provide input to the Page 4 of 5 development of the patent application(s) and any official proceedings prior to filing such applications or other response to proceedings by INHIBITEX. INHIBITEX shall disclose to SYSTEM the complete texts of all patent applications filed by INHIBITEX under the PATENT RIGHTS as well as all information received concerning office actions, the institution or possible institution of any interference, opposition, re-examination, reissue, revocation, nullification or any other official proceeding involving PATENT RIGHTS. All such notifications and disclosures required herein to be made to SYSTEM shall be made no later than ten (10) business days following receipt of such notice.

ADD a new paragraph 5.06 as follows: 5.06 Proprietary Rights. All PATENT RIGHTS hereunder are vested in and owned by SYSTEM. 17. DELETE paragraphs 10.04 and 10.05 in their entirety.
