COLLABORATION AND LICENSE AGREEMENT

This COLLABORATION AND LICENSE AGREEMENT (“Agreement”), effective as of this day of October 16, 2003 (the “Effective Date”), is made by and between Taiho Pharmaceutical Co., Ltd., a corporation organized under the laws of Japan, with a principal place of business at 1-27 Kandanishiki-cho, Chiyoda-ku, Tokyo 101-8444, Japan (“Taiho”), and MethylGene Inc., a corporation organized under the laws of Quebec, Canada with its principal place of business at 7220 Frederick-Banting, Suite 200, Montreal, Quebec H4S 2A1, Canada (“MG”). Each of Taiho and MG shall be referred to as a “Party,” and together as the “Parties.”

BACKGROUND

A. MG has developed certain proprietary technology related to small molecule HDAC Inhibitors (as defined below), which may be useful for developing pharmaceutical products for the treatment and prophylaxis of cancer in humans.

B. Taiho possesses pharmaceutical research, development, manufacturing and commercialization capabilities, as well as proprietary technology in a range of therapeutic fields, including cancer.

C. MG has identified certain novel, proprietary HDAC Inhibitors, including the Compound designated as MGCD 0103, which MG is pursuing as potential development candidates for cancer and for which MG has commenced preclinical development activities.

D. MG and Taiho desire to collaborate to pursue potential commercial development in the cancer field of one or more HDAC Inhibitors, discovered by MG prior to the Effective Date, and discover and potentially commercialize additional HDAC Inhibitors as potential development compounds for cancer, all on the terms and conditions set forth herein.

E. In addition, MG desires to grant to Taiho, and Taiho desires to obtain, an exclusive license from MG of HDAC Inhibitors for use in the Territory (as defined below) in the Field (as defined below), on the terms and conditions set forth herein.

NOW THEREFORE, for and in consideration of the covenants, conditions, and undertakings hereinafter set forth, it is agreed by and between the Parties as follows:

ARTICLE 1
DEFINITIONS

1.1 “Additional Partner” shall mean each third party who is granted by MG, directly or indirectly, a right to market or commercialize Compounds and/or Products in any part of North America or Europe, other than a Non-Cancer Partner or an Opt-out Non-Cancer Partner. As used herein, a “right to market or commercialize” shall include an option or other right to obtain such rights, provided (a) a right that is merely a right of first discussion, and which does not include

an enforceable right to obtain marketing or commercialization rights with respect to Compounds and/or Products in the Field, and (b) a traditional “right of first refusal,” in which the third party has the right to obtain marketing or commercialization rights from MG only in the event of, and on the same terms as reflected in, a bona fide offer made by another third party (and where the rights may be granted to such other third party on such terms, if the right of first refusal is not exercised), shall not in either case alone be deemed a “right to market or commercialize.”

1.2 “Affiliate” shall mean, in the case of a subject entity, another entity which controls, is controlled by or is under common control with the subject entity. For purposes of this definition only, “control” shall mean beneficial ownership (direct or indirect) of at least fifty percent (50%) of the shares of the subject entity entitled to vote in the election of directors (or, in the case of an entity that is not a corporation, in the election of the corresponding managing authority). Notwithstanding the foregoing, the Parties acknowledge that a group of over forty (40) distributors collectively own approximately fifty percent (50%) of Taiho. For the avoidance of doubt, it is agreed that the percentage ownership of Taiho by such distributors shall not be combined together for purposes of determining whether any such distributor is an Affiliate of Taiho.

1.3 “Approved Clinical Studies” shall mean those certain clinical trials of a Compound and/or Product in North America in the Field, as set forth in the Clinical Development Plan and Budget established in accordance with Article 4 below.

1.4 “Approved Preclinical Studies” shall mean those certain Preclinical Development studies in the Field, set forth in the Preclinical Plan and Budget established in accordance with Article 4 below.

It is understood and agreed that MG shall ensure that its agreements with Non-Cancer Partners require such Non-Cancer Partners to abide by Sections 17.4.2, 17.6, 20.2.2, 20.4.2 and Taiho’s right to assign under 22.7, as they relate to the foregoing rights obtained or retained for MG from the Non-Cancer Partners, as if named in place of “MG” therein (including as a “Party”).

8.3.2 Certificate by Additional Partners. At such time as MG enters into an agreement with an Additional Partner, the Additional Partner shall certify to Taiho in writing that the Additional Partner agrees to comply with those provisions referenced in Section 8.3.1(a) above. Taiho’s receipt of such certificate shall be a condition to the Additional Partner’s obtaining any rights from MG. Similarly, upon the request of the Additional Partner, Taiho shall certify to such Additional Partner in writing that Taiho agrees to comply with its obligations to such Additional Partners, under those provisions of this Agreement with which the Additional Partner is required to comply under Section 8.3.1(a) above. MG agrees not to grant any such rights or enter into an agreement with such Additional Partner, and not to provide any Data to such Additional Partner (directly or indirectly, including by way of cross-referencing for purposes of regulatory filings) unless such Additional Partner provides the certificate set forth in this Section 8.3.2, provided that it is agreed that the foregoing shall not prevent MG from providing Data to a potential Additional Partner, for evaluation purposes only, as part of customary and reasonable due diligence by such potential partner prior to entering into an agreement with such potential Additional Partner, subject to reasonable obligations of confidentiality to MG with respect to such Data.

For clarity, it is understood that if the approved labeling for the Product specifies use as a single agent (i.e. not in such combination), the fact that physicians actually use the Product in combination will not caused such Product to be deemed a “Combination Therapy.” In the event the market size for a specific Product marketed as a Combination Therapy for a specific tumor is as large as a market for Products marketed as a single-agent therapy for such tumor, then the Parties will discuss elimination of the […***…] percent ([…***…]%) reduction set forth in Section 10.1.2 with respect to such specific Product and such tumor. Notwithstanding, the […***…] percent ([…***…]%) reductions set forth in Section 10.1.2 shall continue to apply, unless and until, the Parties agree in writing on a change thereto.

10.1.5 Notice and Provision of Data

(a) MG shall promptly notify Taiho upon the submission of each IND in North America with respect to Products in the Field by or under authority of MG, and upon commencement of each Phase I, Phase II and Phase III clinical trial with respect to the Products in the Field by or under authority of MG.

(b) Payment for R&D Events […***…] through […***…] shall be conditioned upon Taiho having received a copy of all Data, including without limitation all Research Data, Preclinical and Clinical Data and Manufacturing Data, existing as of the date such R&D Events are

***Confidential Treatment Requested

triggered, whether generated in or outside of the collaboration hereunder. This paragraph shall not be deemed to limit Section 8.3 above.

(c) With respect to R&D Events […***…] through […***…], in the event the Product and indication triggering such R&D Events (“[…***…] Product” and “[…***…] Indication,” respectively) is not a Product and/or indication that Taiho is then developing in Japan, Taiho may elect not to pay for the achievement of such R&D Event by such Product for such indication. If Taiho so elects, then Taiho shall have no further access to the Data for such […***…] Product with respect to the […***…] Indication (but not including Data that is reasonably necessary for a Product and indication that Taiho is developing) (the “[…***…] Product Data”). Thereafter, in the event Taiho desires to develop such US Product for the US Indication or desires access to such […***…] Product Data, Taiho may notify MG and pay MG for the skipped R&D Events with respect to such […***…] Product for the […***…] Indication, in an amount equal to […***…] the amount that would have been owed for each such skipped R&D Event under this Article 10 had Taiho not elected to skip such R&D Events. Upon such notice and payment, Taiho shall have full access to, copies of and use of any and all […***…] Product Data therefor. For purposes of clarity, a “skipped” R&D Event shall mean only those R&D Events […***…] through […***…] which are otherwise payable under this Article 10 at the time Taiho elected to skip such R&D Event, and for which Taiho elected under this Section 10.1.5(c) not to pay, and provided Taiho did not subsequently pay for such R&D Event with respect to another Product as part of the same Set of R&D Event Payments. In the event Taiho subsequently paid for such R&D Event with respect to another Product as part of the same Set of R&D Event Payments, then such R&D Event shall not be deemed a “skipped” R&D Event, and Taiho shall be entitled to receive all Data with respect to all […***…] Products so skipped. In such event, Taiho may owe a R&D Event payment with respect to such […***…] Products as part of a subsequent Set of R&D Event Payments in accordance with Section 10.1.6 below, but the […***…] set forth in this Section 10.1.5(c) shall not apply thereto. In addition, it is understood that the […***…] amounts paid due to the […***…] set forth in this Section 10.1.5(c) (i.e. the […***…]) shall […***…] under Section 10.2 below. Notwithstanding the foregoing, this Section 10.1.5 shall not apply to R&D Events […***…] and […***…] that are met under the Approved Clinical Studies or by the Initial Clinical Candidate.

10.1.6 Multiple Sets of R&D Event Payments. Until R&D Event […***…] is first achieved […***…], each R&D Event shall be paid for only once, regardless of the number of times such R&D Event is achieved. The amount of such payment shall be determined by the first Product to achieve and trigger payment on such R&D Event (i.e. any adjustment that applies to such first Product shall apply to the payment). Thereafter, the R&D Events shall be paid for in sets, as described below. Each set of payments for R&D Events under this Section 10.1.6 shall be referred to as a “Set of R&D Event Payments.” For purposes of explanation, the effect of the provisions of this Section 10.1.6 is to ensure that, even if the R&D Events are not achieved serially with respect to a single Product at a time, each R&D Event is not paid for more than […***…] until there is one Approved Product, and thereafter not more than a total of […***…] (as […***…] Sets of R&D Event Payments) until there are […***…] Approved Products, and thereafter not more than a total of […***…] times each (as three Sets of R&D Event Payments) until there are […***…] Approved Products, and so on.

***Confidential Treatment Requested

(a) The first Set of R&D Event Payments shall mean only payments for the first achievement of each of R&D Events […***…] through […***…] prior to […***…]. In the event R&D Events […***…],[…***…] and […***…] are achieved thereafter, they shall be paid for in the first Set of R&D Event Payments only if they are triggered by the same Product that triggered […***…]. The achievement of all other R&D Events, if triggering a payment obligation, shall be paid for in a subsequent Set of R&D Event Payments.

(b) Each Set of R&D Event Payments after the first set (e.g. the second set, the third set, etc.) shall become payable, if ever, only upon the triggering of payment of R&D Event […***…] within the immediately previous Set of R&D Event Payments. With respect to each Set of R&D Event Payments, the Product triggering payment of R&D Event […***…] therein shall be referred to as the “Approved Product” for such Set of R&D Event Payments. In the event R&D Events […***…],[…***…] and […***…] are thereafter achieved with respect to a Product, such R&D Events shall be deemed part of that previous Set of R&D Event Payments for which the Approved Product is the same as such Product.

(c) The second (and any subsequent) Sets of R&D Event Payments shall not include R&D Event […***…] (i.e. R&D Event […***…] can only be achieved and become payable as part of the first Set of R&D Event Payments). In addition, with respect to the second (and any subsequent) Sets of R&D Event Payments, the following adjustments shall apply: (i) the payments for R&D Events […***…] and […***…] therein shall not be due unless and until R&D Event 4 therein is triggered, and (ii) the payments for all R&D Events within the second (and any subsequent) Sets of R&D Event Payments shall be reduced by […***…] percent ([…***…]%) in addition to any applicable reductions set forth in Sections 10.1.2, 10.1.3, 10.1.4 and 10.1.5 above.

(d) Within each Set of R&D Event Payments (whether the first set or any subsequent set), each R&D Event shall be paid for at most once, regardless of the number of times such R&D Event is achieved. Payment for each R&D Event within a Set of R&D Event Payments shall be triggered upon its […***…] achievement at any time by a Product that contains a Compound that was not present in any of the Products that triggered payment for the same R&D Event in the previous Sets of R&D Event Payments. For the avoidance of doubt, in the event such […***…] achievement of an R&D Event within a Set of R&D Event Payments occurred prior to the time such Set of R&D Event Payments becomes payable, the payment for such R&D Event shall be made at the time such Set of R&D Event Payments becomes payable, if ever.

10.1.7 Certain Reductions if New Compound. With respect to the […***…] Set of R&D Event Payments, in the event the Product triggering payment on the R&D Events therein contains a New Compound as an active ingredient, then the payments due for such R&D Events shall be reduced by […***…] percent ([…***…]%) respectively.

(b) In the case where the First Approved Product contains a […***…], to the extent the payments made by Taiho for the first Set of R&D Event Payments total less than […***…] Dollars (US $[…***…]) in the aggregate, Taiho agrees to pay commercialization milestones “a,” “b,” “c,” and “d” above at the time such First Approved Product achieves the corresponding Cumulative Net Sales until the total payments to MG under this Section 10.2 with respect to such First Approved Product and the […***…] Set of R&D Event Payments equal […***…] Dollars (US $[…***…]); provided that the amount of each such payment shall be reduced by […***…] percent ([…***…]%) (i.e., each such payment shall equal US $[…***…] rather than US $[…***…]).

10.2.2 Subsequent Approved Products. With respect to Approved Products other than the First Approved Product (each, a “Subsequent Approved Product”), regardless of whether such Product contains a […***…], to the extent the payments made by Taiho for the Set of R&D Event Payments corresponding to such Subsequent Approved Product total less than

***Confidential Treatment Requested

[…***…] Dollars (US $[…***…]), Taiho agrees to pay the commercialization milestones “a”, “b,” “c” and “d” above at the time such Subsequent Approved Product achieves the corresponding Cumulative Net Sales until the total payments to MG under this Section 10.2 with respect to each such Subsequent Approved Product and its corresponding Set of R&D Event Payments equal […***…] Dollars (US $[…***…]), provided that the amount of each such payment shall be reduced by […***…] percent ([…***…]%) (i.e., such payments shall each equal US $[…***…] rather than US $[…***…]).

10.2.3 Certain Terms

(a) “Cumulative Net Sales” shall mean the cumulative total Net Sales of the respective Approved Product in the Territory by Taiho, its Affiliates and Sublicensees over the entire Royalty Term.

(b) Subject to Section 10.2.3 below, Taiho shall pay the amount set forth in the table above with respect to an Approved Product within thirty (30) days after the occurrence of the Cumulative Net Sales thereof first exceeding the respective threshold set forth in the table above.

(c) It is understood and agreed that the total amounts paid by Taiho with respect to each Set of R&D Event Payments plus the total amounts paid by Taiho in commercialization milestones for the Approved Product therein shall not exceed (i) […***…] Dollars (US $[…***…]) in the aggregate in the case of the First Approved Product, where such First Approved Product does not contain a […***…]; (ii) […***…] Dollars (US $[…***…]) in the aggregate in the case of the First Approved Product, where such First Approved Product contains a […***…]; and (iii) […***…] Dollars (US $[…***…]) in the aggregate in the case of each Subsequent Approved Product, regardless of whether or not such Subsequent Approved Product contains a […***…].

10.3 […***…].

10.3.1 Payment upon Marketing Approval in […***…]. Within thirty (30) days after Taiho obtains the first Marketing Approval with respect to the first Product for the first indication in […***…], Taiho agrees to pay MG […***…] Dollars (US $[…***…]), provided that such Product contains a Compound the composition of which is covered by a Valid Claim of Licensed Patents in […***…] or of patent rights owned by Taiho in […***…]. Such payment shall not be subject to any of the adjustments set forth in Section 10.1.

10.3.2 Payment upon Marketing Approval in […***…]. In the event R&D Event […***…] becomes payable with respect to an Approved Product containing a Compound, the composition of which is covered by a Valid Claim of Licensed Patents in […***…] or of patent rights owned by Taiho in […***…], Taiho agrees to pay MG an additional […***…] Dollars (US $[…***…]). Such payment shall not be subject to any of the adjustments set forth in Section 10.1, except for the adjustment set forth in Section 10.1.6(c)(ii) if the triggering R&D Event […***…] occurred in the second or any subsequent Sets of R&D Event Payments. It is understood and agreed that any payment under

***Confidential Treatment Requested

this Section 10.3.2 shall […***…] set forth in Section 10.2 above.

10.3.3 Parallel Imports. Taiho agrees to use diligent efforts to prevent Products sold by Taiho or its Sublicensees for use in […***…] from being resold or distributed outside the Territory.

ARTICLE 11
ROYALTIES

11.1 Payment of Royalties during the Royalty Term. In consideration of the licenses granted to Taiho in Section 8.1 above, beginning with the first commercial sale of Products in a country of the Territory, Taiho shall pay MG a running royalty on the Net Sales of Products sold in such country by Taiho, its Affiliates and Sublicensees during the Royalty Term for such Product in such country, calculated in accordance with this Article 11 and paid in accordance with Article 12 below. The applicable royalty rate shall be as set forth in the table below (subject to any applicable adjustments set forth in this Article 11 below) based on Annual Net Sales of such Product in the Territory. As used herein, “Annual Net Sales” shall mean, with respect to a Product and a calendar year, the Net Sales of such Product sold in the Territory by Taiho, its Affiliates and Sublicensees during such calendar year during the applicable Royalty Term.

NET SALES	ROYALTY PERCENTAGE
With respect to that portion of Annual Net Sales of such Product less than or equal to US $[…*…] Dollars (US $[…*…])	[…***…]	%

With respect to that portion of Annual Net Sales of such Product, greater than US $[…*…] Dollars (US $[……]) and less than or equal to US $[……] Dollars (US $[…*…])	[…***…]	%

With respect to that portion of Annual Net Sales of such Product, greater than US $[…*…] Dollars (US $[……]) and less than or equal to US $[……] Dollars (US $[…*…])	[…***…]	%

With respect to that portion of Annual Net Sales of such Product, greater than US $[…*…] Dollars (US $[…*…])	[…***…]	%

11.1.1 Initial Clinical Candidate not First Approved. In the event the First Approved Product does not contain the Initial Clinical Candidate, and Marketing Approval is obtained hereunder with respect to one or more Products containing […***…], the applicable royalty percentage shall be reduced by […***…] percent ([…***…]%) (i.e. multiplied by […***…]) with respect to such Products containing […***…].

***Confidential Treatment Requested

11.1.2 Initial Clinical Candidate First Approved. In the event the First Approved Product contains the Initial Clinical Candidate, then the applicable royalty percentage shall be (a) decreased by […***…] ([…***…]%) (i.e. subtract […***…]%) with respect to all subsequent Products not containing a […***…] and (b) reduced by […***…] percent ([…***…]%) (i.e. multiplied by […***…]) with respect to all subsequent Products containing […***…].

11.2 Third Party Royalties.

11.2.1 Sharing. In the event Taiho, its Affiliates or Sublicensees pays royalties on their sales of Products in the Field in the Territory, which are in consideration for patent rights, trade secrets or other intellectual property or technology obtained from a non-Affiliate third party (“Third Party IP”), or in the event MG owes royalties to a Non-Affiliate third party who is neither an Additional Partner nor a Non-Cancer Partner on such sales of Products by Taiho, its Affiliates or Sublicensees in the Field in the Territory in consideration for Third Party IP acquired after the Effective Date covering such Products within the Licensed Technology (other than those Third Party IP required to be obtained by MG under Section 8.3), the Parties shall […***…] in the payment of such royalties. Each Party shall promptly notify the other Party of any applicable Third Party IP and the method of calculating royalties owed thereunder to the respective third party. MG agrees not to incorporate into any Product being developed under this Agreement any Third Party IP, which MG has in-licensed or of which MG is otherwise aware, without Taiho’s prior written approval. If after the Effective Date, MG acquires from a third party any Third Party IP within the Licensed Technology that is subject to a royalty to such third party which Taiho would be required to reimburse under this Section 11.2.1, then MG shall promptly notify Taiho, specifying the applicable royalty rate and the method of calculation. Taiho may elect upon written notice at any time to exclude such Third Party IP from the Licensed Technology, and upon such notice, Taiho shall thereafter not be licensed under Section 8.1 with respect to such Third Party IP (“Excluded Third Party IP”) and shall not be obligated to share in the payment of royalties therefor under this Section 11.2.1. The Parties shall discuss from time to time at the JSC whether any Third Party IP is necessary or desirable to obtain with respect to the Compounds and/or Products in the Field.

11.2.2 Adjustment to Running Royalty. In addition to Section 11.2.1, in the event Taiho, its Affiliates or its Sublicensee pays (or reimburses MG for) third party royalties on the sales of a Product(s) in the Territory in consideration for Third Party IP under Section 11.2.1 above, the royalties payable under this Article 11 (after any adjustments under Sections 11.1.1 and 11.1.2) shall be: (i) decreased by the amount of Taiho’s share of such royalties, up to […***…] percentage points ([…***…]%) (i.e. subtract up to […***…]%), in case the Product does not contain a […***…], or (ii) decreased by the amount of Taiho’s share of such royalties, up to […***…] percentage point ([…***…]%) (i.e. subtract up to […***…]%), in case the Product contains a […***…].

11.3 Combination Products. In the event that a Product is sold for a single combined price in combination with other products, components (including active ingredients) or services for which no amounts would be payable to the other Party hereto if sold separately, amounts invoiced for such combination sales for purposes of calculating Net Sales on the sales of the Product in such combination shall be reasonably allocated between such amounts attributable for Product and amounts in consideration for such other products, components or services by the Party under whose

***Confidential Treatment Requested

authority such sale was made. Such allocation shall be based on the relative value(s) of such Product and of such other products, components or services, but in no event shall the Net Sales of the Product in such combination be less than the average arms-length price of such Product, if being sold separately.

11.4 Generic Competition.

11.4.1 Generic Competition Defined. “Generic Competition” shall occur when a product (a “Generic Version”) that contains the same Compound as an active ingredient as in a Product sold in the Field in any country within the Territory by Taiho, its Affiliates or Sublicensees (“Taiho Product”), is sold in such country in the Territory by a third party who is not under authority of Taiho, its Affiliates or Sublicensees, during a period of time within the Royalty Term when the Taiho Product does not have, or loses its marketing exclusivity in such country (whether due to failure to obtain patent protection, or expiration, invalidity of enforceability of Licensed Patents covering the Taiho Product in such country, loss or expiration of any marketing exclusivity conferred by the Regulatory Authority in such country or other cause). The foregoing adjustment shall not apply, however, by reason of sale of a Generic Version that is used solely outside the Field, provided the introduction and sale of such Generic Version does not result in a lower price for the Product hereunder.

11.4.2 Adjustment to Royalties. In the event of Generic Competition occurs with respect to a Taiho Product in any country in the Territory, the royalties payable thereafter under this Article 11 with respect to such Taiho Product sold in such country (after any adjustments under Sections 11.1.1, 11.1.2 and 11.2.2) shall be reduced by […***…] percent ([…***…] %). Notwithstanding the foregoing, this Section 11.4.2 shall not apply to Net Sales of Taiho Products in […***…].

ARTICLE 12
PAYMENTS; BOOKS AND RECORDS

12.1 Quarterly Royalty Reports. Commencing on the first commercial sale of Products in the Territory, Taiho shall make quarterly reports to MG within […***…] days after the end of each calendar quarter, which reports shall include, in reasonable detail, a calculation of any Net Sales in such quarter and an itemization of any deductions or adjustments applicable to such Net Sales by the categories set forth in Section 1.25. Concurrently with making such report, Taiho shall remit payment to MG for any royalty due under Article 11 above.

12.2 Payment Method. All payments under this Agreement shall be made by bank wire transfer in immediately available funds to an account designated by the payee. All dollar amounts specified in this Agreement, and all payments made hereunder, are and shall be made in U.S. dollars. Any payments due under this Agreement which are not paid by the date such payments are due under this Agreement shall bear interest to the extent permitted by applicable law at the U.S. prime rate per annum quoted by the Wall Street Journal (U.S., Eastern Edition), or its successor, on the first business day after such payment is due, plus an additional two percentage points (2%), calculated on the number of days such payment is delinquent. This Section 12.2 shall in no way limit any other remedies available to either Party.

***Confidential Treatment Requested

12.3 Currency Conversion. If any currency conversion shall be required in connection with the calculation of amounts payable hereunder, such conversion shall be made using the TTS (Telegraphic Transfer Selling) rate for conversion of the foreign currency into U.S. dollars, quoted for current transactions reported by Bank of Tokyo-Mitsubishi, or its successor, for the last business day of the calendar quarter to which such payment pertains.

12.4 Taxes. Each Party shall bear and, except as otherwise expressly provided in this Section 12.4, pay any and all taxes, duties, levies, and other similar charges (and any related interest and penalties), however designated, imposed on that Party as a result of the existence or operation of this Agreement. If in the paying Party’s judgment, laws or regulations require that taxes be withheld, the paying Party will (i) deduct those taxes from the remittable payment, (ii) timely pay the taxes to the proper taxing authority, and (iii) send proof of payment to the other Party within sixty (60) days following that payment. It is understood that if the paying Party believes there is a likelihood that taxes must be withheld, then it may do so and shall not be deemed in breach of this Agreement by reason of such withholding.

12.5 Records; Inspection.

12.5.1 General. Each Party and its Affiliates shall keep complete, true and accurate books of accounts and records for the purpose of determining payments due pursuant to this Agreement. Such books and records shall be kept for at least […***…] years following the end of the calendar quarter to which they pertain. Such records will be open, for such […***…] year period, for inspection at the principal place of business of such Party or its Affiliates, as the case may be, (“Audited Party”) during such three (3) year period by an independent auditor chosen by the other Party (“Auditing Party”) and reasonably acceptable to the Audited Party for the purpose of verifying the amounts payable by Audited Party hereunder. All such inspections may be made no more than once each calendar year, at reasonable times and on reasonable notice. The independent auditor shall be obligated to execute a reasonable confidentiality agreement prior to commencing any such inspection.

12.5.2 Sublicensees. Taiho shall either: (a) require each of its Sublicensees to maintain similar books and records and to open such records for inspection to an independent auditor chosen by MG and reasonably acceptable to such Sublicensee in the manner paralleling that set forth in Section 12.5.1, or (b) obtain such audit rights from the Sublicensee for itself and exercise such audit rights on behalf of MG upon MG’s request and disclose the results thereof to MG. In either case MG shall be deemed the Auditing Party, and such Sublicensee the Audited Party for purposes of Section 12.5.3 below.

12.5.3 Costs. Inspections conducted under this Section 12.5 shall be at the expense of the Auditing Party, unless a variation or error producing an underpayment in amounts payable exceeding […***…] percent ([…***…]%) of the amount paid for the period covered by the inspection is established in the course of any such inspection, whereupon the Audited Party shall reimburse the Auditing Party for all reasonable out-of-pocket costs relating to the inspection for such period. The Parties will endeavor to minimize disruption of the Audited Party’s normal business activities to the extent reasonably practicable.

The Additional Partner shall maintain or have maintained batch records and take such other actions as is necessary to comply with applicable laws and regulations, and to otherwise cooperate reasonably with Taiho to ensure consistent and adequate supply of such materials.

14.5 Terms of Supply by MG and the Additional Partners. In supplying Compound and/or Product to Taiho in accordance with Section 14.3 or 14.4 above, MG and the Additional Partner shall supply the same in an expeditious manner and shall comply with standards of performance at least equivalent to those generally expected for the supply of bulk compounds and pharmaceutical products by top-tier toll manufacturers. Upon the request of Taiho, the Additional Partner shall enter into a written agreement with Taiho with respect to such supply containing terms and conditions that are commercially reasonable (including without limitation reasonable and customary forecasting and ordering provisions) but in any case not less protective of Taiho than those set forth in this Agreement. In the event there are not sufficient quantities of a particular Compound or Product, then Taiho shall be allocated a reasonable share of the available quantities. In the event Taiho procures Compound or Product from an Additional Partner, and the Additional Partner thereafter ceases to have the right to manufacture such Compound or Product, the Additional Partner shall continue to supply the same to Taiho in accordance with Section 14.5 until Taiho is able, using Commercially Reasonable and Diligent Efforts, to procure adequate alternative supply. In such event, the Additional Partner shall use Commercially Reasonable and Diligent Efforts to assist Taiho in obtaining such alternative supply, and in transitioning the manufacturing process to the alternative manufacturer. All supplies of Compounds and Products to Taiho under this Article 14 by MG and/or Additional Partners shall be F.O.B. […***…], unless otherwise agreed.

(b) In the event that a Transitioned Product is commercialized by MG, its Affiliates or licensees in the Field in the Territory, MG shall pay to Taiho a royalty on net sales of such Transitioned Product by MG, its Affiliates or licensees at the rates set forth below based on the last stage of development (i.e. the highest applicable percentage below) conducted in any regulatory jurisdiction worldwide by or under authority of Taiho or MG with respect to such Transitioned Product at the time of termination of this Agreement, as follows.

Stage of Development	Royalty
[…***…]	[…***…]	%
[…***…]	[…***…]	%
[…***…]	[…***…]	%
[…***…]	[…***…]	%

It is understood that, in connection with establishing the royalties under this Section 20.4.4(b), the ancillary terms of such royalty, such as the term for which such royalties are due, the definition of MG’s net sales, royalty reporting, audit rights, royalty offsets and the like will also be established, which terms will be no less favorable to Taiho than the corresponding terms of this Agreement for MG.

ARTICLE 21
DISPUTE RESOLUTION

21.1 Arbitration.Any dispute, controversy or claim with respect to the breach, interpretation or enforcement of this Agreement, including disputes relating to termination of this Agreement, shall be settled by binding arbitration in the manner described in this Section 21.1. The arbitration shall be conducted by the Judicial Arbitration and Mediation Services, Inc. (“JAMS”) under its rules of arbitration then in effect. Notwithstanding those rules, the following provisions shall apply to the arbitration hereunder:

21.1.1 Arbitrators. The arbitration shall be conducted by a single JAMS arbitrator; provided that at the request of either Party, the arbitration shall be conducted by a panel of three (3) arbitrators, with one (1) JAMS arbitrator chosen by each of Taiho and MG and the third appointed by the other two (2) arbitrators. If the Parties are unable to agree upon a single arbitrator, or the third arbitrator in case of a panel of three (3), such single or third arbitrator (as the case may be) shall be appointed in accordance with the rules of JAMS. In any event, the arbitrator or arbitrators selected in accordance with this Section 21.1.1 are referred to herein as the “Panel” and

***Confidential Treatment Requested

shall be comprised of arbitrators who are familiar with worldwide research and business development in the biotechnology industry, unless otherwise agreed.

21.1.2 Proceedings. Except as otherwise provided herein, the Parties and the arbitrators shall use their best efforts to complete the arbitration within nine (9) months after the appointment of the Panel under Section 21.1.1 above, unless a Party can demonstrate to the Panel that the complexity of the issues or other reasons warrant the extension of one or more of the time tables. In such case, the Panel may extend such time table as reasonably required. The Panel shall, in rendering its decision, apply the substantive law of the State of New York, without regard to its conflicts of laws provisions, except that the interpretation of and enforcement of this Article 21 shall be governed by the U.S. Federal Arbitration Act. The proceeding shall take place in San Francisco, California. The decision and/or award rendered by the arbitrator(s) shall be written, final and non-appealable, and judgment on such decision and/or award may be entered in any court of competent jurisdiction. The fees of the Panel shall be paid by the losing Party which Party shall be designated by the Panel. If the Panel is unable to designate a losing Party, it shall so state and the fees shall be split equally between the Parties. Each Party shall bear the costs of its own attorneys’ and experts’ fees; provided that the Panel may in its discretion award the prevailing Party all or part of the costs and expenses incurred by the prevailing Party in connection with the arbitration proceeding.

21.1.3 Interim Relief. Notwithstanding anything in this Article 21 to the contrary, Taiho and MG shall each have the right to apply to any court of competent jurisdiction for a temporary restraining order, preliminary injunction, or other similar interim or conservatory relief, as necessary, pending resolution under the above described arbitration procedures. Nothing in the preceding sentence shall be interpreted as limiting the powers of the arbitrators with respect to any dispute subject to arbitration under this Agreement. The Panel may award injunctive relief.

ARTICLE 22

Notwithstanding the foregoing, the Parties have agreed on a press release that can be used to describe this transaction and the terms and conditions of this Agreement, and each Party acknowledges and agrees that the other Party may disclose information from the mutually agreed press release at any time and from time to time without the consent of the other Party.

orders or restrictions, failure of suppliers, or any other reason where failure to perform is beyond the reasonable control of the nonperforming Party. In such event Taiho or MG, as the case may be, shall promptly notify the other Party of such inability and of the period for which such inability is anticipated to continue. Without limiting the foregoing, the Party subject to such inability shall use reasonable efforts to minimize the duration of any force majeure event.

22.4 No Implied Waivers; Rights Cumulative.No failure on the part of Taiho or MG to exercise and no delay in exercising any right under this Agreement, or provided by statute or at law or in equity or otherwise, shall impair, prejudice or constitute a waiver of any such right, nor shall any partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right.

Any assignment in contravention of the foregoing shall be void and of no effect. Any change of control of a Party shall be deemed an assignment of this Agreement by such Party, and neither Party shall enter into or become the subject of a change of control, unless the party acquiring such control and its ultimate parent operating company agrees to be bound by this Agreement and to ensure that its Affiliates comply with the terms hereof. Neither Party shall transfer nor assign any substantial asset relating to this Agreement, unless the acquiring Party agrees in writing to honor the other Party’s rights under this Agreement with respect to such asset.

22.8 Modification.No amendment or modification of any provision of this Agreement shall be effective unless in writing signed by all Parties. No provision of this Agreement shall be varied, contradicted or explained by any oral agreement, course of dealing or performance or any other matter not set forth in an agreement in writing and signed by all Parties.

22.9 Severability.If any provision hereof should be held invalid, illegal or unenforceable in any jurisdiction, the Parties shall negotiate in good faith a valid, legal and enforceable substitute provision that most nearly reflects the original intent of the Parties and all other provisions hereof shall remain in full force and effect in such jurisdiction and shall be liberally construed in order to carry out the intentions of the Parties as nearly as may be possible. Such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of such provision in any other jurisdiction.

22.10 Counterparts.This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, and all of which together, shall constitute one and the same instrument.

22.11 Headings.Headings used herein are for convenience only and shall not in any way affect the construction of or be taken into consideration in interpreting this Agreement.

MG agrees to promptly execute any documents, make any filings and provide any other reasonable assistance to Taiho in order to record, complete and perfect in Taiho the foregoing security interest. MG covenants that it shall not grant to any third party a security interest in the Licensed Patents in
