(a) VIVUS agrees to transfer to MTPC, free of charge, its ownership of the TRADEMARK as VIVUS used for the ORAL PRODUCT, provided, however, that the Parties shall, upon request of VIVUS, execute an exclusive TRADEMARK license agreement under which VIVUS and its SUBLICENSEE, shall be granted exclusive rights to use said TRADEMARK for the ORAL PRODUCT in the TERRITORY as long as VIVUS continues the marketing of the ORAL PRODUCT in the TERRITORY. Under such TRADEMARK license agreement, VIVUS shall pay to MTPC a royalty equal to two percent (2%) of the NET SALES of the ORAL PRODUCT marketed with such TRADEMARK for the first three (3) years following expiration of this Agreement, and a royalty equal to one percent (1%) of the NET SALES of

the ORAL PRODUCT marketed with such TRADEMARK for two (2) additional years thereafter. Thereafter, VIVUS shall be free to use such TRADEMARK in conjunction with the marketing and sale of ORAL PRODUCTS in the TERRITORY free of charge.

(b) Notwithstanding the foregoing Section 21.1(a), to the extent VIVUS continues the marketing of the ORAL PRODUCT in the TERRITORY under a TRADEMARK, then upon written request by VIVUS, MTPC agrees to waive the right to have the ownership of the TRADEMARK to be transferred to MTPC as set forth in Section 21.1(a). In such case, the Parties shall execute a simple agreement under which VIVUS continues to maintain the ownership of the TRADEMARK for the ORAL PRODUCT in the TERRITORY, and VIVUS shall pay, in consideration for MTPC’s waiving such rights, to MTPC the amounts equal to two percent (2%) of the NET SALES of the ORAL PRODUCT marketed with such TRADEMARK for the first three (3) years following expiration of this AGREEMENT, and the amounts equal to one percent (1%) of the NET SALES of the ORAL PRODUCT marketed with such TRADEMARK for two (2) additional years thereafter. Thereafter, VIVUS shall be free to use such TRADEMARK in conjunction with the marketing and sale of ORAL PRODUCTS in the TERRITORY free of charge.

(a) VIVUS agrees to transfer to MTPC, free of charge, its ownership of the TRADEMARK as VIVUS used for the PRODUCT, and VIVUS shall immediately stop using such TRADEMARK. Thereafter, VIVUS shall not use any trademark which is similar to or confusing with the TRADEMARK.

(b) VIVUS shall, upon MTPC’s request, if applicable, provide to MTPC or its nominee, free of charge, all the DRUG APPROVAL APPLICATION and REGULATORY APPROVAL for the PRODUCTS (in the event VIVUS has

not applied for DRUG APPROVAL APPLICATION or REGULATORY APPROVAL for a particular PRODUCT in a particular country, VIVUS shall provide to MTPC all the INFORMATION VIVUS reasonably would have included in such application or approval). MTPC shall only use the VIVUS INFORMATION contained with such DRUG APPROVAL APPLICATION or REGULATORY APPROVAL for applying for and obtaining regulatory approval for the PRODUCTS, and not for any other use.

(c) MTPC or its nominee(s) shall have the optional rights to take over all or any part of the remaining stocks of the BULK DRUG SUBSTANCE and the PRODUCT in the warehouses and factories of VIVUS at such prices as may be agreed between the Parties. VIVUS shall not thereafter market or manufacture any PRODUCT covered by this Agreement. In case MTPC or its nominee(s) do not exercise the optional rights to take over the stocks of the BULK DRUG SUBSTANCE and the PRODUCT pursuant to this Section 21.2(c), VIVUS shall have the right to sell the residual salable or usable stocks of the PRODUCT for the term of six (6) months after the termination of this AGREEMENT, provided that the payment defined in this AGREEMENT for such remaining stocks shall be made accordingly.

(d) Notwithstanding anything to the contrary in this AGREEMENT, to the extent a SUBLICENSEE is conducting its business in good standing and without any breach under sublicensing agreement with VIVUS (hereinafter referred to as the “SUBLICENSE AGREEMENT”) at the time of the termination of this AGREEMENT by MTPC pursuant to Sections 20.2 and 20.3 due to VIVUS’s breach or insolvency or by VIVUS for any reason in accordance with this AGREEMENT, MTPC shall use its commercially reasonable efforts to enter into a direct license agreement with such SUBLICENSEE, as soon as practicable (but not later than *** months after the termination). Under such direct license agreement, MTPC shall, subject to subsection (b) below, grant such SUBLICENSEE a direct license having substantially the same terms and conditions of this AGREEMENT (including, without limitation, exclusivity, royalty rates and term) with modifications on certain terms and conditions to reflect the TERRITORY and FIELD granted to such SUBLICENSEE under SUBLICENSE AGREEMENT. Such SUBLICENSEE shall have the right to continue to operate under the terms of the SUBLICENSE AGREEMENT, subject to subsection (b) below, during the period from termination of this AGREEMENT until the earlier of (i) the effective date of the direct license

agreement or (ii) the expiration of the said *** month period without entering into a direct license agreement with MTPC in spite of good faith discussion by MTPC and such SUBLICENSEE. In no event shall MTPC (a) be liable to SUBLICENSEE for any actual or alleged breach of such SUBLICENSE AGREEMENT by VIVUS or (b) have any obligations to such SUBLICENSEE that are (x) not stipulated in this AGREEMENT (including but not limited to manufacturing and supply obligations etc.), (y) in conflict of or in excess of a material term of this AGREEMENT or (z) in conflict of applicable laws or regulations. Each SUBLICENSEE shall be an intended third party beneficiary of this Section 21.2(d).”

8. The Parties agree that Appendix G attached to the Parties’ “Second Amendment to Agreement” dated August 1, 2012 shall be valid for another period of *** months from the Amendment Effective Date.

9. This Amendment may be executed in one (1) or more counterparts, each of which shall for all purposes be deemed to be an original and all of which shall constitute the same instrument. This Amendment may be executed by facsimile signature, which shall be effective. Upon the execution of this Amendment by MTPC and VIVUS, this Amendment shall be binding upon the Parties to the AGREEMENT.

10. Except as set forth in this Amendment, the remainder of the AGREEMENT shall remain in full force and effect and shall be binding on all parties thereto; provided, however, that to the extent a provision in this Amendment conflicts with a provision in the AGREEMENT, then the provision in this Amendment shall control.

11. This Amendment is entered into in the English language. In the event of any dispute concerning the construction or meaning of this Amendment, reference shall be made only to this Amendment as written in English and not to any translation into any other language.
