In the event LICENSOR does not wish to take the necessary action to defend or to protect the Patent Rights or the Trademarks or to prosecute any infringement of the Patent Rights or the Trademark(s), LICENSEE shall have the right, but not the obligation, to do so at LICENSEE's expense, and in such case, any proceeds resulting from such action shall be the exclusive property of LICENSEE.

An Adverse event ("AE") is defined as: 1. any experience which is adverse, including what are commonly described as adverse or undesirable experiences, adverse 29 events, adverse reactions, side effects, or death due to any cause associated with, or observed in conjunction with the use of a drug, biological product, or device in humans, whether or not considered related to the use of the Product: (i) occurring in the course of the use of the Product, (ii) associated with, or observed in conjunction with Product overdose, whether accidental or intentional, (iii) associated with, or observed in conjunction with Product abuse, and/or (iv) associated with, or observed in conjunction with Product withdrawal. 2. any significant failure of expected pharmacological or biological therapeutic action (with the exception of in clinical trials). B. Serious or Non-Serious is defined as: 1. A serious AE is one that is life threatening or fatal, permanently disabling, requires in-patient hospitalization or prolonged hospitalization, or is a congenital anomaly, cancer or overdose. In addition, end organ toxicity, including hematological, renal, hepatic, and central nervous system AEs, may be considered serious. In laboratory tests in animals, a serious AE includes any experience suggesting significant risk for human subjects. 30 2. A non-serious AE is any AE which does not meet the criteria for a serious AE. C. Life-threatening is defined as: the patient is at immediate risk of death from the AE as it occurs. D. End-Organ Toxicity is defined as: A medically significant event or lab value change in which a patient may not necessarily be hospitalized or disabled, but is clinically significant enough to warrant monitoring (e.g. seizures, blood dyscrasias). E. Expected or unexpected is defined as: 1. Expected AE - An AE which is listed in the Investigator's Brochure for clinical trials, included in local labelling (e.g., Summary of Product Characteristics) for Marketed Drugs, or in countries with no local labelling, in the Corporate Standard Prescribing Document. 2. Unexpected AE - An AE that does not meet the criteria for an expected AE or an AE which is listed but differs from that event in terms of severity or specificity. F. Associated with or related to the use of the drug is defined as: A reasonable possibility exists that the AE was caused by the Product. G. Un-associated or unrelated to the use of the Product is defined as one that does not meet the criteria for associated or related to the use of the Product. 10.3 All initial reports and follow-ups (oral or written) for any and all serious and unexpected AEs (other than with 31 respect to animal studies) which become known to a party (other than from disclosure by or on behalf of the other party) must be communicated by telephone or telefax to the other party within twenty four (24) hours upon receipt of the information by the disclosing party with written confirmation to follow as soon as it becomes available, but in no event later than three days after initial communication of the AE. 10.4 For AEs from animal studies which suggest a potential significant risk for humans, a written report must be forwarded to the other party as soon as the results are received by the party making the report. 10.5 Within thirty (30) days of receipt of a request from the other party, but not more often than as required by any regulatory agency, each party will give the other party a print out or computer disk of all AEs reported to it and its Affiliates relating to either Product within the last year. 10.6 If either party wishes access to AE reports of the other party relating to a Product, upon request of that party the other party shall make available its records (including computer disks) for viewing and copying by the other party. 10.7 Disclosure of information hereunder by a party to the other party shall continue as so long as either party and/or its Affiliates or designees continue to clinically test or market a Product. LICENSEE's obligations regarding AE reporting relate to territories in the world that are the subject of a license or 32 other commercial relationship for Product between LICENSOR and LICENSEE. 10.8 LICENSEE shall make timely submissions of safety reports to regulatory authorities in the countries in the Territory as required by local law.

ARTICLE 15 NON-WAIVER ---------- 15.1 Either party's failure, at any time, to exercise or enforce any right conferred upon it hereunder, shall not be deemed to be a waiver of any such right or operate to bar the exercise or performance thereof at any time or times thereafter, nor shall its waiver of any right hereunder at any given time, including rights to any payment, be deemed a waiver thereof for any other time. ARTICLE 16 ASSIGNMENT ---------- 16.1 Subject to the provisions of this Article 16, neither this Agreement nor any of the rights or obligations hereunder shall be assigned by either party by judicial process or otherwise, to any person, firm, company or corporation without the prior written consent of the other party, except that LICENSOR shall have the right to assign this Agreement in the event (i) LICENSOR is absorbed by merger into a third party other than into any of its Affiliates, or (ii) LICENSOR sells, transfers and assigns all of its assets including all its rights, 39 title and interest to the Product to any third party other than any of LICENSOR's Affiliates, or (iii) there is a change in the stock ownership of LICENSOR so that such ownership falls under the "control" of a third party other than any of LICENSOR's Affiliates.
