8. Section 7.2 of the AGREEMENT shall be deleted in its entirety and replaced by the

following;

“7.2 Manufacture of the BULK DRUG SUBSTANCE and the BULK DRUG TABLET by VIVUS. During the SUPPLY PERIOD, each of MTPC and VIVUS shall use its commercially reasonable efforts to implement the technical transfer relating to the STARTING MATERIALS, BULK DRUG SUBSTANCE and BULK DRUG TABLETS from MTPC to VIVUS and/or CMOs identified and qualified by VIVUS; provided that VIVUS shall use its commercially reasonable efforts to limit the number of potential CMOs to no more than *** for each of the STARTING MATERIALS, BULK DRUG SUBSTANCE and BULK DRUG TABLETS. The details of the technical transfer, such as, to clarify the assigned tasks and its expenses either on VIVUS and/or on MTPC, to specify the number of CMOs for the STARTING MATERIALS, BULK DRUG SUBSTANCE and BULK DRUG TABLETS to perform the technical transfer as well as their capability, and to clarify the end-point of the technical transfer, shall be negotiated in good faith and agreed upon in writing by the Parties, provided, however, that basic understanding of the Parties for the allocation of the cost, expense and responsibility for such technical transfer is as follows:

Each of VIVUS and MTPC agrees to use its respective commercially reasonable efforts to achieve the technical transfer schedule to be agreed upon by the Parties.

VIVUS agrees to (i) undertake activities to identify and qualify CMOs acceptable to VIVUS, and (ii) be responsible for necessary technical transfers for such CMOs, provided, that in identifying and qualifying CMOs, VIVUS shall coordinate such qualification activities with MTPC in good faith and when appropriate so as to achieve a smooth and definite technical transfer to such CMOs. MTPC shall use its commercially reasonable efforts to assist VIVUS in the process of identifying and qualifying CMOs and technical transfer to CMOs. In this regard, MTPC shall provide technical and commercial details and MTPC KNOW-HOW in the form of documentation and consultation to allow the successful identification and qualification of the CMOs and technical transfers, such as, (i) a complete copy of the open and closed portions of the DMF and the ASMF (each as defined below) for CMOs to manufacture the BULK DRUG SUBSTANCE and/or BULK DRUG TABLET, (ii) a complete copy of the API batch record, (iii) names and introductions to suppliers of STARTING MATERIALS, (iv) specific and verifiable MANUFACTURING COST, including, without limitation, prices for STARTING MATERIALS, (v) MTPC’s BULK DRUG SUBSTANCE and BULK DRUG

TABLET manufacturing plan attached hereto as Appendix F, (vi) any documents, information, access to MTPC manufacturing facilities and assistance necessary to achieve the technical transfer, and (vii) any other documents reasonably required by potential CMOs. MTPC shall provide the documents and information set forth in items (i)-(v) of the preceding sentence at its earliest possible convenience, but within *** after execution of this Amendment.

Each Party shall bear its own costs and expenses with regard to identification and qualification of CMOs and technical transfer to VIVUS and CMOs; provided that the material costs for STARTING MATERIALS, BULK DRUG SUBSTANCE and BULK DRUG TABLETS that will be required to qualify the CMOs shall be paid by VIVUS as set forth below.

MTPC shall supply the STARTING MATERIALS, BULK DRUG SUBSTANCE and/or BULK DRUG TABLET to VIVUS for purposes of the qualification of, or technical transfer to CMOs at *** in case of the STARTING MATERIALS, at *** for BULK DRUG SUBSTANCE, and at *** in case of the BULK DRUG TABLET; provided, however that the quantities of such STARTING MATERIALS, BULK DRUG SUBSTANCE and BULK DRUG TABLETS for the qualification of CMOs or technical transfer shall be agreed upon by the Parties from time to time to assure (i) sufficient quantities of the BULK DRUG TABLET for COMMERCIAL SALES and PROMOTIONAL SAMPLES consistent with VIVUS’s sales forecast and (ii) the earliest possible date for the transfer of manufacturing to CMOs.

MTPC shall also transfer the title as the holder of the DMF and ASMF to VIVUS to expedite the transfer of manufacturing to CMOs and the technical transfer. As used in this Section 7.2, “DMF” and “ASMF” means the Drug Master File filed with the FDA or the Active Substance Master File filed with the EMA for the BULK DRUG SUBSTANCE manufactured at Onoda Factory by Mitsubishi Tanabe Pharma Factory Ltd. The exact timing and form of the foregoing transfers shall be determined by VIVUS at its sole and reasonable discretion based on guidance from regulatory consultants and/or the responsible regulatory authorities. Such transfer of title to the DMF and ASMF shall occur automatically at the time determined by VIVUS, and MTPC agrees to take all reasonable actions necessary to effectuate or record such transfer, consistent with the form of transfer determined by VIVUS. Following such transfer, VIVUS shall be the sole holder of the DMF and ASMF. However, VIVUS acknowledges that all data and information

included in the DMF and ASMF (collectively, “REGULATORY FILE INFORMATION”) shall be and remain the exclusive property of MTPC, subject to the license set forth in the following sentence. MTPC hereby grants to VIVUS a perpetual, irrevocable, fully paid, royalty-free, transferable, sublicenseable (through multiple tiers), non-exclusive license to use, disclose, copy, distribute, create derivative works of, practice, and otherwise exploit the REGULATORY FILE INFORMATION for any and all purposes; provided, VIVUS agrees that it shall (i) take reasonable measures to protect the secrecy of and avoid unnecessary disclosure and unauthorized use of the REGULATORY FILE INFORMATION and (ii) take at least those measures that it takes to protect its own confidential information and shall ensure that each THIRD PARTY granted access to the REGULATORY FILE INFORMATION are bound by confidentiality and non-use obligations with respect to such information. Notwithstanding the foregoing, nothing herein shall prevent VIVUS from disclosing the REGULATORY FILE INFORMATION to comply with applicable laws or regulations, including, without limitation, disclosures to regulatory agencies and courts or tribunals of competent jurisdiction.”

“7.3 Supply of the BULK DRUG SUBSTANCE and/or BULK DRUG TABLET. During the ROYALTY PERIOD, the BULK DRUG SUBSTANCE and/or BULK DRUG TABLET shall be manufactured by VIVUS or its CMOs. MTPC shall use its commercially reasonable effort to assist VIVUS to be supplied STARTING MATERIALS directly from MTPC’s current suppliers of such STARTING MATERIALS for VIVUS’s or its CMO’s use for manufacture of the BULK DRUG SUBSTANCE during the SUPPLY PERIOD. Notwithstanding the foregoing, the BULK DRUG SUBSTANCE and/or BULK DRUG TABLET may be supplied by MTPC at the supply prices and under the terms and conditions to be agreed in writing by the Parties during the ROYALTY PERIOD. Upon request by VIVUS made at least *** prior to the end of the SUPPLY PERIOD, the Parties shall start good faith negotiations on such supply prices, terms and conditions, provided, however, that MTPC shall not have any obligation to supply the BULK DRUG SUBSTANCE and/or BULK DRUG TABLET unless agreed with VIVUS through such good faith discussions.”

10. Section 7.4 shall be added to the AGREEMENT as follows;

“7.4 Suppliers of the STARTING MATERIALS to MTPC. During the SUPPLY PERIOD, if MTPC reasonably judges identification and qualification of alternative suppliers of the STARTING MATERIALS to be used for manufacturing of the BULK DRUG SUBSTANCE by MTPC are necessary to satisfy the demand of the BULK DRUG SUBSTANCE of VIVUS during the SUPPLY PERIOD or to lower the cost for the STARTING MATERIALS, BULK DRUG SUBSTANCE and/or BULK DRUG TABLET, MTPC shall (i) bear the costs and expenses in identifying and qualifying such alternative STARTING MATERIAL suppliers incurred and (ii) provide the technical transfer for such alternative STARTING MATERIALS suppliers at its cost and expense. In the event VIVUS identifies any alternative STARTING MATERIALS suppliers which can supply the STARTING MATERIALS that (i) are needed to satisfy VIVUS’s demand for the BULK DRUG SUBSTANCE and BULK DRUG TABLETS or (ii) will reduce the cost of a STARTING MATERIAL by *** percent (***%) or more, MTPC agrees to undertake commercially reasonable efforts to qualify such alternative STARTING MATERIAL suppliers. ”

11. Section 8.1 of the AGREEMENT shall be amended to read as follows;

13. Existing Section 11.1 of the AGREEMENT shall be renumbered as Section 11.1.1 and shall be deleted in its entirety and replaced by the following;

“11.1.1 Supply Price for the BULK DRUG TABLET for COMMERCIAL SALE.
