CONFIDENTIAL TREATMENT HAS BEEN REQUESTED WITH RESPECT TO THE OMITTED PORTIONS. 1 <PAGE> "control" shall mean the ownership (whether directly or indirectly) of forty-nine percent (49%) or more of the voting stock or other equity interest or the ability (whether directly or indirectly) to determine the policy or actions of any entity on account of contract or other relationships. NALTREXONE-Naltrexone, its physiologically active salts, derivatives, precursors or other chemical form of naltrexone which provides the physiological activity of naltrexone. THE PROJECT 1. (a) DAS hereby establishes a research project with SOUTHERN (hereinafter the "Project"), the purpose of which is to develop the product(s) listed in Exhibit A (hereinafter the "PRODUCT"). (b) During the term of this RESEARCH AGREEMENT, SOUTHERN will undertake the Project described in Paragraph l(a) exclusively for DAS [* * *]. (c) SOUTHERN grants to DAS an exclusive option to license the PRODUCT developed during the term of this RESEARCH AGREEMENT (hereinafter said term shall be referred to as the "Option Period"). The purpose of such option to license is for DAS to evaluate its interest in commercializing the PRODUCT. The payment for such option to license shall be in the amount and shall occur pursuant to Paragraph 3(a) herein. DAS' rights under this option to license are described in Paragraph 8 herein. (d) Nothing contained herein shall be interpreted to preclude SOUTHERN at any time from undertaking efforts similar to those performed under this RESEARCH AGREEMENT for third parties or for internal utilization, provided that such efforts do not involve the PRODUCT or a product which is directly competitive with PRODUCT for a period of three (3) years from the completion of the Project and thereafter, so long as DAS is in clinical studies with the PRODUCT or is paying royalties to SOUTHERN under a license agreement for PRODUCT. By "directly competitive with PRODUCT" is intended a slow release depot product dispensing a compound which can serve at least in part as an opioid antagonist and can serve as a competitive substitute in the marketplace for PRODUCT. TERM 2. (a) This RESEARCH AGREEMENT and the Option Period shall become effective on the date written above and shall terminate the earlier of three years (3 years) thereafter or upon completion of the services which DAS may require for entering and performing clinical studies toward the commercialization of PRODUCT, except as otherwise provided herein. It is the intent of the parties that a PRODUCT acceptable to DAS shall be delivered to DAS not later than [* * *] from the initiation of the development set forth in the Proposal. (b) Paragraphs 5, 6, 7, 8, 9, 10, 11, and 12 shall survive the termination of this RESEARCH AGREEMENT.

This notice shall be given at least [* * *] in advance of the desired termination date. DAS shall pay to SOUTHERN in full for all of SOUTHERN's activities occurring under this RESEARCH AGREEMENT through the date of termination. In the event that DAS terminates this RESEARCH AGREEMENT prior to delivery of PRODUCT, SOUTHERN agrees to negotiate with DAS reasonable compensation for DAS' payments prior to such termination in the event that SOUTHERN enters into a subsequent research agreement for naltrexone microspheres and employs Product Technology developed under this RESEARCH AGREEMENT. Such compensation shall take into consideration the fact of DAS' termination, the total amount paid by DAS, the extent to which the Product Technology will be used, the savings in performing such future research which SOUTHERN will enjoy, the period of time elapsing between the termination by DAS and the entering into such subsequent research agreement, and such other considerations which are relevant to the determination of compensation. (d) The term of this RESEARCH AGREEMENT and the Option Period can be extended subject to mutual agreement in writing between DAS and SOUTHERN. CHARGES AND INVOICING 3. (a) Upon signing of this RESEARCH AGREEMENT, DAS shall immediately pay SOUTHERN [* * *] for the option to license described in Paragraph l(c) herein, which option shall remain in effect for a period of one (1) year. Thereafter, the option may be extended for a second year by a payment of [* * *] and for a third year by a payment of [* * *]. (b) DAS' liability for the payment of charges in carrying out the Project shall not exceed [* * *] without the written consent of DAS. Promptly after execution of this Agreement and in not more than fifteen (15) days, DAS shall give to SOUTHERN [* * *] as a prepayment to be maintained as a credit against future payments until the remaining amount of payment is [* * *] or less. Notwithstanding the above, if SOUTHERN fails to provide a product fulfilling the specifications set forth in the Proposal, then DAS shall have a free option for three (3) years from the date of initiation of the Project. (c) DAS shall pay to SOUTHERN the sum of the charges incurred during each month within 30 days of the invoice date. (d) SOUTHERN reserves the right to terminate this RESEARCH AGREEMENT and the option to license, if DAS fails to pay any invoice [* * *] from the invoice date.
