Unless otherwise agreed upon by the Parties hereto, TOBIRA shall not have any right to use the Information for any purposes other than those specifically set forth in the first sentence of this Article 2.A.

B.	De-Blocking Provision. In addition, subject to the terms and conditions contained herein, and subject to TAKEDA’s receipt of TOBIRA’s payment of the upfront milestone pursuant to Article 4.A.(i), TAKEDA shall not enforce with respect to:

(i)

the patents and patent applications listed in Schedule 2.B. attached hereto, including all patents arising from such applications and any addition, division, continuation, continuation-in-part, substitution, extension, renewal, reissue, confirmation or import thereof or therefor, including their extension if any, or

(ii)

(hereinafter above (i) and (ii) are collectively referred to as the “Ancillary Patents”), against TOBIRA, its Affiliate(s) and Sublicensee(s) (or any of its or

Confidential

their permitted successors or assigns) with regard to the development, manufacture and commercialisation of the Compounds or Products in the Territory during the term of the Ancillary Patents. For the avoidance of doubt, such non-enforcement commitment of TAKEDA shall apply only with regard to the development, manufacture and commercialisation of the Compounds or Products in the Territory, and TAKEDA shall not be restricted to enforce the Ancillary Patents against TOBIRA, its Affiliate(s) and Sublicensee(s) (or any of its or their permitted successors or assigns) with regard to any other purposes. With regard to the Ancillary Patents, TAKEDA shall not be under any obligations, including without limitation obligation to prosecute or maintain the Ancillary Patents, and TAKEDA shall be entitled to dispose of , abandon or modify them at its sole discretion, provided, however, that TAKEDA (a) shall not grant a license to any Affiliate or any Third Party under the Ancillary Patents which is in conflict with the covenant granted to TOBIRA hereunder, or (b) shall not transfer the Ancillary Patents to any Affiliate or any Third Party, without securing the covenants granted to TOBIRA hereunder. If there exist any other patent(s) or patent application(s) which fall under the above-mentioned definition of the Ancillary Patents, then such patent(s) or patent application(s) shall be added to and treated as the Ancillary Patents.

Obligations on Sub-Licensing and Granting of Rights. Except as otherwise provided for in Article 2.E., TOBIRA shall impose on all its Affiliates, Sublicensee(s) and Third Party marketing partners any and all obligations imposed hereunder on TOBIRA, including without limitation those specifically stipulated herein as the obligation of TOBIRA and/or its Affiliates and/or its Sublicensee(s), and shall be responsible to TAKEDA for the performance of such obligations not only by itself but also by its Affiliates, Sublicensee(s) and Third Party marketing partners.

Confidential

Trademarks. TOBIRA shall market the Products throughout the Territory under a trademark or trademarks selected by TOBIRA among from TOBIRA’s trademark inventory (collectively, the “Trademarks”). Except as otherwise expressly provided in this Agreement, TOBIRA shall own all right, title and interest in and to such Trademarks. TAKEDA hereby acknowledges TOBIRA’s exclusive ownership rights in the Trademarks and the TOBIRA name and logo.

General Access to HIV Therapies on Public Health Grounds. TOBIRA and TAKEDA are aware that the Product could become an important milestone in the fight against HIV. TAKEDA also recognizes the fact that TOBIRA may actively support under ethical aspects effective strategies, initiatives and programmes of governmental as well as other non-governmental and private organizations particularly in the developing world for the fight against HIV. In consideration thereof nothing in this Agreement shall restrict TOBIRA, in circumstances in which TOBIRA considers it reasonable to do so, to grant Public Health Access Licenses of the Assigned Patents and/or the Information or to make the Product available through Access Programmes, provided however that TOBIRA shall notify TAKEDA in writing thereof after granting such Public Health Access License or commencing such Access Programme. TOBIRA shall not be obligated to impose on its licensees under the Public Health Access License the obligations imposed hereunder on TOBIRA, provided, however, that, if TOBIRA grants a Public Health Access License or if TOBIRA makes the Product available through Access Programmes, TOBIRA shall always do so at TOBIRA’s sole cost, risk and responsibility.

F.	Combination Products and Co-Packaged Products. TOBIRA shall further have the right to market, distribute and sell (i) the combination Product (i.e., a formulation of the Product which contains at least one (1) other

Confidential

therapeutically active ingredient in addition to a Compound “Combination Product”) and (ii) the Product as a single packaged product containing Product and one or more active ingredients as separate components (“Co-packaged Product”). For the avoidance of doubt, the foregoing sentence shall not mean that TAKEDA hereby grants or shall be obligated to grant TOBIRA a license to develop and/or commercialize any other of TAKEDA’s proprietary compounds than the Compounds even if such other TAKEDA’s proprietary compounds can be (i) used in combination with the Compound, or (ii) co-packaged and commercialized with the Product.

TAKEDA shall cooperate with TOBIRA for such procedures, including without limitation signing and submitting to TOBIRA the documents prepared by TOBIRA for such patent (application) owner name change, at TOBIRA’s cost. For the avoidance of doubt, TOBIRA shall not take any procedures for the assignment of the Assigned Patents, until and unless Takeda has deleted, amended or disclaimed the claimed inventions other than those of the Compounds, and/or has taken the necessary actions to move such deleted, amended or disclaimed inventions into the Other Patents as set forth in Article 3.A.

Maintenance of Assigned Patents. After the assignment of the Assigned Patents, such Assigned Patents (including the Specific Compound Scope, if and after such Specific Compound Scope is assigned to TOBIRA pursuant to above Article 4.A.) shall be maintained by TOBIRA, at its own discretion, responsibility and expenses, pursuant to Article 13.A. TOBIRA shall, without obtaining TAKEDA’s prior written consent, not attempt to expand the scope of what is claimed in the Assigned Patents, nor file divisional(s), continuous patent application(s) nor continuous in-part patent application(s) derived from the Assigned Patents.

Confidential

once only upon occurrence of the following respective trigger events, and payable in US Dollars pursuant to the following instalments within (a) thirty (30) days after the respective trigger event with regard to instalments i. to vi. below; and (b) only with regard to the instalments under the following vii. to ix., within sixty (60) days after the end of the first calendar year in which [*]


	Trigger Event	Milestone Payment

[*]	[*]	[*]

For the avoidance of doubt, (i) should it become clear that the [*] the relevant milestone payment corresponding to [*] mentioned above, as the case may be, shall be due at the time when such fact becomes clear, and, even if such fact does not become clear, such payment shall be due at the latest, together with the immediately following milestone payment, upon occurrence of such the immediately following trigger event, and (ii) each milestone shall be payable only once at the first achievement of the relevant milestone event and TOBIRA shall not be required to make the milestone payments for the Product(s) containing the Reserve Compound (hereinafter called the “Reserve Product”) for the same trigger events for which TOBIRA had already made such milestone payments with regard to the Product(s) containing the Principal Compound (hereinafter called the “Principal Product”), if any, and vice versa, as stipulated in Article 6.B.

Royalty Calculation and Payments. In addition to the consideration as provided for in Article 4.A. hereof and in accordance with the terms of this Agreement, TOBIRA shall pay to TAKEDA tiered royalties in US Dollars based on the cumulative worldwide annual Net Sales of the Product sold in the Territory by TOBIRA and its Affiliate(s) and Sublicensee(s) in each calendar year according to the sliding scale below. For each country of the Territory, TOBIRA shall pay TAKEDA royalties for the period commencing on the date of the First Commercial Sale of the first Product in such country and ending on the later of the followings:

(a)

the twelfth (12th) anniversary of the First Commercial Sale of the Product in such country or the Generic Entry, whichever is earlier; and

Confidential

(b)

the date of expiration of the last to expire of the Assigned Patents in such country, calculated on a country-by-country basis (hereinafter called the “Royalty Period”). The royalties shall be paid quarterly by TOBIRA to TAKEDA within sixty (60) days after the last day of each quarter and the rate of royalties on annual Net Sales in the Territory during the Royalty Period shall be as follows:

(i)

[*] on the portion of such Net Sales of the Products up to [*];

(ii)

[*] on the portion of such Net Sales of the Products over [*] up to [*];

(iii)

[*] on the portion of such Net Sales of the Products [*] up to [*]; and

(iv)

[*] on the portion of such Net Sales of the Products over [*].

For the avoidance of doubt, (i) the Principal Product and the Reserve Product shall hereunder be treated independently in relation to the duration of the Royalty Period, and the Royalty Period for the Reserve Product shall continue on a country-by-country basis, regardless of the Royalty Period for the Principal Product, until the later of (a) the twelfth (12th) anniversary for the First Commercial Sale of the Reserve Product in such country or the Generic Entry, whichever is earlier; and (b) the date of expiration of the last to expire of the Assigned Patents for the Reserve Compound and/or the Reserve Product, but (ii) in the calculation of the annual Net Sales, both the

Confidential

Principal Product and the Reserve Product shall be calculated into one. By way of example, if in a certain year, the Net Sales of the Principal Product which is subject to the royalty payment is [*] and the Net Sales of the Reserve Product which is subject to the royalty payment is [*], then the amount of royalty for such year pursuant hereto is, [*].

Exempt Sales and Transfers. Notwithstanding the provisions of this Article 4, TOBIRA shall not be obligated to pay royalties on transfers of the Compound or the Product within the scope of Access Programmes, even if such transfers give rise to Net Sales, provided, however, that, if the price of the Compounds or the Product thus transferred by TOBIRA within the scope of the Access Programme exceeds [*] of the then prevailing average selling price of the Compounds or the Product transferred to a Third Party by TOBIRA and/or its Sublicensee(s) in the United States, then such transfer of the Product shall not be deemed to be made under the Access Programme and TOBIRA shall be obligated to pay royalties to TAKEDA on such transfer as well.

Royalties from Public Health Access Licenses etc. In the event that TOBIRA earns revenues from any Public Health Access Licenses, TOBIRA shall not be obligated to pay royalties on such revenues to TAKEDA, if and as far as such Public Health Access Licenses are granted at a consideration of running royalties the rate of which is not more than [*] of the net sales of the Product by such Third Party. If the Public Health Access Licenses are granted by TOBIRA at a consideration of running royalties the rate of which is more than [*] of the net sales of the Product by such Third Party, then the portion of the running royalties exceeding [*] of the net sales of the Product by such Third Party shall be added to the Net Sales.

Confidential

Third Party Patents. If it is essential or desirable for TOBIRA to exploit the license granted to it by TAKEDA under this Agreement in any country that TOBIRA obtains a license from one or more Third Parties under such Third Parties’ issued patent or patents, then TOBIRA shall obtain such license at its own risk and costs.

Combination Products and Co-Packaged Products. Net Sales of the Combination Product and the Co-packaged Products shall be calculated by multiplying the total Net Sales of the Combination Product or the Co-packaged Product by the fraction A/(A+B), where A is [*] of TOBIRA and/or its Affiliate(s) or Sublicensee(s) in the applicable country of the Product containing the Compound as its sole therapeutically active ingredient sold separately in the same formulation/dosage and having the same approved indication, and B is [*] weighted by the IMS gross sales in the calendar quarter for which royalties are being calculated hereunder in the applicable country of the products containing each of the other active ingredients as their sole therapeutically active ingredients in the Combination Product and/or of the separate components co-packaged with the Product sold separately in the same formulation/dosage and having the same approved indication, during the applicable calendar quarter. If A or B cannot be determined because values for the Product or the other product containing the other active ingredients than the Compound sold alone are not available in a particular country in question, then thus non-available A or B, as the case may be, shall be the average price weighted by the IMS gross sales in the calendar quarter for which royalties are being calculated hereunder at which the Product or the other active ingredients are sold alone in the dosage included in the Combination Product or Co-packaged Product in the U.S. In the event that no Products or other active ingredients are sold alone in any country of the Territory, the Parties shall negotiate in good faith an allocation of the fair market value of the Product in the Combination Product or the Co-packaged Product.

Confidential

Sales and Royalty Reporting. From the date of the First Commercial Sale until the expiry of the Royalty Period and within sixty (60) days of the end of each calendar quarter, TOBIRA shall send to TAKEDA a report, on a Product-by-Product basis, stating (a) the gross sales and the Net Sales of the Product sold by TOBIRA, its Affiliate(s) and its Sublicensee(s) on a country-by-country basis in local currency with respect to such calendar quarter, (b) the currency exchange rates used to determine the royalties payable, and (c) a calculation of the amount payable to TAKEDA pursuant to this Article 4.

Withholding Tax. Income tax on any payments made to TAKEDA under this Agreement shall be borne by TAKEDA. TOBIRA shall deduct any withholding taxes and other statutory duties levied on the payments by TOBIRA to TAKEDA pursuant to this Agreement and shall pay such withholding taxes and other statutory duties to the proper tax authorities as required by applicable law at the date of payment. TOBIRA shall maintain official receipts of payment of any withholding taxes and forward these receipts to TAKEDA without any undue delay. The Parties shall exercise reasonable efforts to ensure that any withholding taxes and other statutory duties imposed are reduced as far as possible under the provisions of the current or any future double taxation agreement between Japan and the U.S.

I.	Conversion Rates. Conversion from other currencies into US Dollars shall be made using the daily rate of exchange published by The Wall Street Journal (Eastern edition), on the last working day of the calendar quarter to which the payment relates.

J.	Audit Rights. TOBIRA and its Sublicensee(s) shall keep accurate records in sufficient detail concerning the Net Sales of the Product. TAKEDA may

Takeda to License CCR5 Antagonists for Treatment of HIV Infection to Tobira Therapeutics, Inc.

Osaka, Japan and San Diego, August 1, 2007 – Takeda Pharmaceutical Company Limited (“Takeda”) and Tobira Therapeutics, Inc. (“Tobira”) today announced that they have entered into an agreement pursuant to which exclusive worldwide rights to develop, manufacture and commercialize Takeda’s anti-HIV investigational compounds TAK-220 and TAK-652 are granted to Tobira.

Upon conclusion of the agreement, Takeda will receive from Tobira an upfront payment as well as development and commercialization milestone payments and royalty on sales of products. Further details of economic conditions are not disclosed.

TAK-652 and TAK-220 are CCR5 antagonists that can be administered orally and bind CCR5 receptors to interfere with the entry of the HIV-1 virus into macrophages and activated T-cells by inhibiting fusion between viral and cellular membranes.

This mechanism of action is different from those currently used for treatment of HIV infection such as nucleoside reverse transcriptase inhibitors and protease inhibitors. TAK-220 and TAK-652 are currently in Phase I clinical development in the U.S. and Europe. All future development activities in these territories will be conducted by Tobira.
