MERCK shall pay to ARIAD the Estimated Loss if any, within 10 days of receiving the Estimate.

(d) If ARIAD, after delivering the Estimate, becomes aware of additional information which would cause it to adjust its estimates of Operating Income/(Loss) for a calendar month, such information shall be reported in the next monthly report and the Estimated Operating Income Payment or Estimated Loss for the following calendar month shall be adjusted accordingly.

4.3.3 Quarterly Reports, Payments.

(a) Within forty five (45) days following the end of each Calendar Quarter commencing on and after the Effective Date, each of ARIAD and MERCK shall submit to the JSC and the other Party all Commercialization Expenses and License Fees (defined in Schedule 3 to this Agreement) incurred by it with respect to, as well as for ARIAD the Net Sales and Cost of Goods applicable to, such Co-Promoted Product in the U.S. Territory.

-51-

(b) The amount of the Operating Income Payments payable to MERCK shall be paid by ARIAD within thirty (30) days following issuance of such written report; provided, that, in the event that a Co-Promoted Product experiences a Loss over any Calendar Quarter, MERCK shall pay ARIAD the MERCK Revenue Share Percentage of such Loss within thirty (30) days of the issuance of such written report, in each case net of the Estimated Operating Income Payment or Estimated Loss already paid by each Party with respect to such Calendar Quarter

4.3.4 Audit Rights. ARIAD shall keep and maintain for [***] years complete and accurate records of all Commercialization Expenses incurred in the Commercialization of Co-Promoted Products and of Net Sales of Co-Promoted Products (“Co-Development Net Sales”) in the U.S. Territory in sufficient detail to allow confirmation of same by the JSC and MERCK. MERCK shall have the right for a period of [***] years after such Commercialization Expenses and Co-Development Net Sales are reconciled in accordance with Section 4.3.2 to appoint at its expense an independent certified public accountant reasonably acceptable to ARIAD to audit the relevant records of ARIAD and its Affiliates to verify that the amount of such Commercialization Expenses and Co-Development Net Sales are correctly determined. ARIAD and its Affiliates shall each make its records available for audit by MERCK or such independent certified public accountant during regular business hours at such place or places where such records are customarily kept, upon [***] days written notice from MERCK. Such audit right shall not be exercised by MERCK more than once in any Calendar Year and no period may be audited more than once. All records made available for audit shall be deemed to be Confidential Information of ARIAD. The results of each audit, if any, shall be binding on both Parties. In the event there was an error in the amount of such Commercialization Expenses and Co-Development Net Sales reported by ARIAD hereunder, (a) if the effect of the error resulted in an underpayment, ARIAD shall promptly (but in any event no later than [***] days after ARIAD’s receipt of the report so concluding) make payment to MERCK of the underpayment amount and (b) if the effect of the error resulted in an overpayment, MERCK shall promptly (but in any event no later than [***] days after MERCK’s receipt of the report so concluding) make payment to ARIAD of the overpayment amount. MERCK shall bear the full cost of such audit unless such audit discloses an underpayment by ARIAD of the greater of [***] percent ([***]%) of the aggregate amount of MERCK’s share of Operating Income in any Calendar Year or $[***], in which case ARIAD shall reimburse MERCK for all costs incurred by MERCK in connection with such audit.

4.5 Determination that Milestone Events have Occurred; Treatment of Combinations; Treatment of Combined Phase 1/2 or Phase 2/3 Clinical Studies.

(a) MERCK shall provide ARIAD with prompt written notice upon each occurrence of a milestone event set forth in Section 4.4.1. In the event that, notwithstanding the fact that MERCK has not given such a notice, ARIAD believes any such milestone event has occurred, it shall so notify MERCK in writing and shall provide to MERCK data, documentation or other information that supports its belief. Any dispute under this Section 4.5 that relates to whether or not a milestone event has occurred shall first be referred to the JSC to be resolved in accordance with Section 2.1.5, but if not resolved as set forth in Section 2.1.5, it shall be subject to arbitration under Section 12.1.

(b) A Combination Product containing a Product shall not be entitled to any milestone that has already been earned by that Product or any other Combination Product containing that same Collaboration Compound as that Combination Product.

(c) In the event of a Clinical Trial which is both a Phase 1 Clinical Trial and a Phase 2 Clinical Trial (commonly referred to as a “Phase 1/2 Clinical Trial”), the milestone payable upon the occurrence of Initiation of the Phase 2 Clinical Trial shall be payable by MERCK (x) upon Initiation of the Phase 2 segment if there are separate segments delineated in the protocol for such Clinical Trial as Phase 1 and Phase 2 or (y) upon Initiation of the Phase 1/2 Clinical Trial if there are not separate segments delineated in the protocol for such Clinical Trial as Phase 1 and Phase 2.

(d) In the event of a Phase 2 Clinical Trial used as a pivotal trial for seeking Commercialization Regulatory Approval for a Product for an Indication (commonly referred to as a “Phase 2/3 Clinical Trial”), the milestone payable upon occurrence of Initiation of the Phase 2 Clinical Trial shall be payable by MERCK upon Initiation of such trial and the milestone payable upon occurrence of Initiation of the Phase 3 Clinical Trial shall be payable by MERCK upon the date when either Responsible Party determines that it will file for Commercialization Regulatory Approval in its Territory based on the results of said Phase 2/3 Clinical Trial.

(e) In the event that a milestone is paid for an Indication for a Product and Development of such Product for such Indication is subsequently terminated, such milestone payment shall be creditable against the same milestone payment earned for a different Product for the same Indication.

-55-

(f) For purposes of determination of the occurrence of the milestone events, all Products containing the same single active pharmaceutical ingredient or the same combination of active pharmaceutical ingredients shall be considered the same Product, regardless of differences in formulation.

4.6 Payment of Royalties; Royalty Rates; Accounting and Records.

4.6.1 Payment of Royalties.

(a) Royalties Applicable in ROW Territory.

(i) MERCK shall pay ARIAD a royalty based on Annual Net Sales of each Royalty-Bearing Product in each Calendar Year (or partial Calendar Year) commencing with the First Commercial Sale of such Product in any country in the ROW Territory and ending upon the last day of the last Royalty Term for such Product, at the following rates:

Annual Net Sales Increment in ROW Territory	Royalty Rate (%)
Up to $[***]	[***]%
Above $[*], but less than $[*]	[***]%
Above $[***]	[***]%

(ii) In the event that one or more Third Parties sell a Competing Drug (as defined below) in any country in the ROW Territory in which a Royalty-Bearing Product is then being sold by MERCK, then, during any Calendar Quarter in which sales of the Competing Drug by such Third Parties are greater than [***] percent ([***]%) of MERCK aggregate unit sales of Products and Competing Drugs in such country for the treatment of cancer (as measured by prescriptions or other similar information available from a Third Party Data Provider and applicable to such country) the applicable royalties in effect with respect to such Royalty-Bearing Product in such country as specified in Section 4.6.1(a)(i) [***] percent ([***]%). Notwithstanding the foregoing, MERCK’s obligation to pay royalties at the full royalty rates shall be reinstated on the first day of the Calendar Quarter immediately following the Calendar Quarter in which sales of such Competing Drugs account for [***] percent ([***]%) or less of MERCK aggregate unit sales of Products and Competing Drugs for the treatment of cancer in such country. For purposes of this Section 4.6.1(a)(ii), a “Competing Drug” means a pharmaceutical product that contains a Collaboration Compound as an active ingredient and is bioequivalent to such Product.

(b) Royalties Applicable in U.S. Territory.

-56-

(i) On and after the date of U.S. Commercialization Transfer with respect to a Product, (x) such Product shall thereafter be a Royalty-Bearing Product for purposes of this Agreement; and (y) MERCK shall pay ARIAD a royalty based on Annual Net Sales of each such Royalty-Bearing Product in each Calendar Year (or partial Calendar Year) commencing with the First Commercial Sale of such Royalty-Bearing Product in the U.S. Territory after the U.S. Commercialization Transfer and ending upon the last day of the Royalty Term for such Product in the U.S. Territory, at the following rates:

Annual Net Sales Increment in U.S. Territory	Royalty Rate (%)
Up to $[***]	[***]%
Above $[***]	[***]%

The following hypothetical example illustrates the calculation of royalties under this Section 4.6.1(b)(i): If, in any Calendar Year during the Term, Annual Net Sales of a Royalty-Bearing Product are $[***], the applicable royalty would be $[***], [***]% of Net Sales for Net Sales up to $[***] ($[***]), and [***]% of Net Sales for Net Sales of $[***] ($[***] [***]).

(ii) In the event that one or more Third Parties sell a Competing Drug (as defined above) in the U.S. Territory, then, during any Calendar Quarter in which sales of the Competing Drug by such Third Party are greater than [***] percent ([***]%) of the aggregate unit sales of Products and Competing Drugs in the U.S. Territory for the treatment of cancer (as measured by prescriptions or other similar information available from a Third Party Data Provider and applicable to the U.S. Territory ) the applicable royalties in effect with respect to such Royalty-Bearing Product in the U.S. Territory as specified in Section 4.6.1(b)(i) shall be reduced by [***] percent ([***]%). Notwithstanding the foregoing, MERCK’s obligation to pay royalties at the full royalty rates shall be reinstated on the first day of the Calendar Quarter immediately following the Calendar Quarter in which sales of such Competing Drugs account for [***] percent ([***]%) or less of aggregate sales of Products and Generic Products for the treatment of cancer in the U.S. Territory.

(c) Combination Products. In the event that a Royalty-Bearing Product is sold as part of a Combination Product, where “Combination Product” means any unified dose (e.g. not a kit of two separate and distinct drug dosage forms) of a pharmaceutical product which is comprised of Royalty-Bearing Product and one or more other compound(s) and/or ingredients having independent therapeutic effect (collectively the “Other Products”), Net Sales of Royalty-Bearing Product, for the purposes of determining royalty payments, shall be determined by multiplying the Net Sales of the Combination Product by the fraction, [***] where [***]. In the event that no such separate sales are made of either the Royalty-Bearing Product or the Other Products, the reasonably estimated commercial value thereof will be used instead of the sale price. Each of “weighted average sale price” and “reasonably estimated commercial value” shall be determined as follows:

-57-

“Weighted average sale price” and “reasonably estimated commercial value,” as the case may be, for a Royalty-Bearing Product and Other Products shall be calculated once at the commencement of each Calendar Year and such amount shall be used during all applicable royalty reporting periods for the entire following Calendar Year. When determining the weighted average sale price of a Royalty-Bearing Product or Other Products, the weighted average sale price shall be calculated by dividing the Net Sales (translated into U.S. dollars in accordance with Section 4.6.5 hereof) by the units of active ingredient sold during the [***] (or the number of [***]) of the preceding Calendar Year for the respective Royalty-Bearing Product or Other Products. “Reasonably estimated commercial value” shall be determined by agreement of the Parties using criteria to be mutually agreed upon by the Parties. If the Parties do not agree, such dispute shall be resolved in accordance with Section 12.1 hereof. [***] a forecasted weighed average sale price will be used for the Royalty-Bearing Product and Other Products, if applicable. Any over or under payment due to a difference between forecasted and actual weighted average sale prices will be paid or credited in the first royalty payment [***].

(d) Combinations of Product with a Diagnostic Product. In the event that a Royalty-Bearing Product is sold with a Diagnostic Product that is not the subject of a Diagnostic Product Agreement, the allocation of the combined price of the Royalty-Bearing Product and such Diagnostic Product will be allocated between the Royalty-Bearing Product and such Diagnostic Product by agreement of the Parties based on the reasonably estimated commercial value thereof.

(e) Royalty Stacking. The amount of (A) royalties owing to ARIAD under Section 4.6.1(a)(i) and (B) royalties owing to ARIAD under Section 4.6.1(b)(i), in each case, for any Royalty-Bearing Product in any country, shall be [***] percent ([***]%) of the amount of royalties incurred by MERCK or any of its Affiliates to any Third Party in consideration for the license of Patent Rights in such country if, at the time of sale of the Royalty-Bearing Product such Patent Rights would be infringed by the use, sale or import of the Royalty-Bearing Product in such country in the Field in the absence of such a license; provided, however, that in no event shall the royalties owed under Section 4.6.1(a)(i) or Section 4.6.1(b)(i), with respect to a Royalty-Bearing Product in a country be reduced by operation of this Section 4.6.1(e), together with either Section 4.6.1(a)(ii) or Section 4.6.1(b)(ii), [***] percent ([***]%) of what would otherwise be owed under 4.6.1(a)(i) or Section 4.6.1(b)(i) with respect to such Royalty-Bearing Product. For purposes of this Section 4.6.1(e), the amount of royalties owing to ARIAD under Section 4.6.1(a)(i) or Section 4.6.1(b)(i) for Annual Net Sales of any Royalty-Bearing Product in a given country (prior to the [***]% [***] provided for herein)shall be deemed to be that amount which would be owed if Annual Net Sales of such Royalty-Bearing Product in such country subject to each of the royalty rates under Section 4.6.1(a)(i) or Section 4.6.1(b)(i) were proportional to Net Sales of such Royalty-Bearing Products in all countries subject to royalties under Section 4.6.1(a)(i) or Section 4.6.1(b)(i). For clarity, an example of the application of the preceding sentence is as follows: If sales in a calendar year in countries in the ROW Territory without royalty owed to Third Parties are $[***] [***] and sales in countries in the ROW Territory with a [***] percent ([***]%) royalty owed to Third Parties are $[***], the royalties will be $[***], calculated as follows: ($[***] [***] x [***]% + [***] x [***]%) + ($[***] x [***]% + [***] x [***]%) = $[***].

(f) Limit on Royalty Reductions. Notwithstanding Sections 4.6.1(a)(ii), 4.6.1(b)(ii) or 4.6.1(c), in no event shall the royalties owed under Section 4.6.1(a)(i) or Section 4.6.1(b)(i), with respect to a Royalty-Bearing Product in a country be reduced by operation of Section 4.6.1(c), together with either Section 4.6.1(a)(ii) or Section 4.6.1(b)(ii), [***] percent ([***]%) of what would otherwise be owed under 4.6.1(a)(i) or Section 4.6.1(b)(i) with respect to such Royalty-Bearing Product in such country.

-58-

(g) Application of Reductions to Royalty Tiers. For purposes of Sections 4.6.1(a)(ii), 4.6.1(b)(ii) or 4.6.1(c), the amount of royalties owing to ARIAD under Section 4.6.1(a)(i) or Section 4.6.1(b)(i) for Annual Net Sales of any Royalty-Bearing Product in a given country (prior to any [***] provided for therein)shall be deemed to be that amount which would be owed if Annual Net Sales of such Royalty-Bearing Product in such country subject to each of the royalty rates under 4.6.1(a)(i) or Section 4.6.1(b)(i) were proportional to Net Sales of such Royalty-Bearing Product in all countries subject to royalties under Section 4.6.1(a)(i) or Section 4.6.1(b)(i), whichever is applicable.

(h) Know-How Payments. The Parties hereby acknowledge and agree that any royalties that may be payable for a Product for which no Patent Rights exist shall be in consideration of (i) ARIAD’s expertise and know-how concerning mTOR Inhibitor Compounds, including its development of the ARIAD Background Technology and its other development activities conducted prior to the Effective Date; (ii) the performance by ARIAD of the Development Program; (iii) the disclosure by ARIAD to MERCK of results obtained in the Development Program; (iv) the licenses granted to MERCK hereunder with respect to Licensed Technology and Joint Technology that are not within the claims of any Patent Rights Controlled by ARIAD; (v) the restrictions on ARIAD in Section 6.4.1; (vi) the “head start” afforded to MERCK by each of the foregoing; and (vii) ARIAD’s co-promotion of Products in the U.S. Territory.

(i) Payment Dates and Reports. Royalty payments shall be made by MERCK within thirty (30) days after the end of each calendar month, commencing with the calendar month in which the First Commercial Sale of a Royalty-Bearing Product occurs. MERCK shall also provide, at the same time each such payment is made, a report showing: (a) the Net Sales of each Royalty-Bearing Product by type of Royalty-Bearing Product and country in the Territory; (b) the total amount of deductions from gross sales to determine Net Sales; (c) the applicable royalty rates for Royalty Bearing Product in each country in the Territory after applying any reductions set forth above; and (d) a calculation of the amount of royalty due to ARIAD.

4.6.2 Records; Audit Rights. MERCK and its Affiliates and Sublicensees shall keep and maintain for [***] years from the date of each payment of royalties hereunder complete and accurate records of gross sale and Net Sales by MERCK and its Affiliates and Sublicensees of each Royalty-Bearing Product, in sufficient detail to allow royalties to be determined accurately. ARIAD shall have the right for a period of [***] years after receiving any such payment to appoint at its expense an independent certified public accountant reasonably acceptable to MERCK to audit, the relevant records of MERCK and its Affiliates and Sublicensees to verify that the amount of such payment was correctly determined. MERCK and its Affiliates and Sublicensees shall each make its records available for audit by such independent certified public accountant during regular business hours at such place or places where such records are customarily kept, upon thirty (30) days written notice from ARIAD. Such audit right shall not be exercised by ARIAD more than once in any Calendar Year or more than once with respect to sales of a particular Product in a particular period. All records made available for audit shall be deemed to be Confidential Information of MERCK. The results of each audit, if any, shall be binding on both Parties. In the event there was an underpayment by MERCK hereunder, shall promptly (but in any event no later than thirty (30) days after MERCK’s receipt of the report so concluding) make payment to the ARIAD of any shortfall. ARIAD shall bear the full cost of such audit unless such audit discloses an underreporting by MERCK of the greater of [***] percent ([***]%) of the aggregate amount of royalties payable in any Calendar Year or $[***], in which case MERCK shall reimburse ARIAD for all costs incurred by ARIAD in connection with such audit.

-59-

4.6.3 Overdue Royalties and Milestones. All royalty payments not made within the time period set forth in Section 4.6.1 or Operating Income payments not made within the time period set forth in Section 4.3.2, including underpayments discovered during an audit, and all milestone payments not made within the time period specified in Section 4.4.1, shall bear interest at a rate of [***] percent ([***]%) per month from the due date until paid in full or, if less, the maximum interest rate permitted by Applicable Laws. Any such overdue royalty or milestone payment shall, when made, be accompanied by, and credited first to, all interest so accrued.

4.6.4 Payments;Withholding Tax.

(a) All payments made by a Party under this Article 4 shall be made by wire transfer from a banking institution in the United States in U.S. Dollars in accordance with instructions given in writing from time to time by the other Party.

(b) If applicable laws, rules or regulations require withholding of income or other taxes imposed upon any payments made by MERCK to ARIAD under Agreement, MERCK shall make such withholding payments as may be required and shall subtract such withholding payments from such payments. MERCK shall submit appropriate proof of payment of the withholding taxes to ARIAD within a reasonable period of time. MERCK shall promptly provide ARIAD with the official receipts. MERCK shall render ARIAD reasonable assistance in order to allow ARIAD to obtain the benefit of any present or future treaty against double taxation which may apply to such payments. If MERCK did not withhold taxes, in whole or in part, in connection with any payment it made to ARIAD under the Agreement and a tax authority subsequently disagrees with MERCK's interpretation of the withholding rules and finds that MERCK had a duty to withhold taxes and such taxes were assessed against and paid by MERCK, then ARIAD will indemnify and hold harmless MERCK from and against such taxes (excluding penalties).

8.2 Legal Actions.

8.2.1 Third Party Infringement.

(a) In General.

(i) Notice. In the event either Party becomes aware of (i) any suspected infringement of any ARIAD Patent Rights or MERCK Patent Rights through the development or commercialization of an mTOR Inhibitor in the Field, or (ii) the submission by any Third Party of an abbreviated new drug application under the Hatch-Waxman Act for a product in the Field that includes a Collaboration Compound (each, an “Infringement”), that Party shall promptly notify the other Party and provide it with all details of such Infringement of which it is aware (each, an “Infringement Notice”). The JSC shall promptly meet to discuss the Infringement and to determine the collective overall strategy for patent enforcement.

(ii) ARIAD Right to Enforce. Unless otherwise determined by the JSC as part of its consideration of an overall patent strategy for Patent Rights involving Products, in the event that such an Infringement occurs in the U.S. Territory and a U.S. Commercialization Transfer has not occurred, ARIAD shall have the first right and option to address such Infringement by taking reasonable steps, which may include the institution of legal proceedings or other action. All costs, including, without limitation, attorneys’ fees, relating to such legal proceedings or other action shall be borne by ARIAD and shall be Commercialization Expenses. If ARIAD does not take or initiate commercially reasonable steps to eliminate the Infringement within one hundred twenty (120) days from any Infringement Notice (or twenty (20) days in the case of an Infringement resulting from the submission by any Third Party of an abbreviated new drug application under the Hatch-Waxman Act), then MERCK shall have the right and option to do so at its expense, which shall be a Commercialization Expense.

(iii) MERCK Right to Enforce. Unless otherwise determined by the JSC as part of its consideration of an overall patent strategy for Patent Rights involving Products, in the event that such an Infringement occurs in the ROW Territory or in the event such Infringement occurs in the U.S. Territory after a U.S. Commercialization Transfer, MERCK shall have the first right and option to address such Infringement by taking reasonable steps, which may include the institution of legal proceedings or other action. All costs, including, without limitation, attorneys’ fees, relating to such legal proceedings or other action shall be borne by MERCK. If MERCK does not take or initiate commercially reasonable steps to eliminate the Infringement within one hundred twenty (120) days from any Infringement Notice (or twenty (20) days in the case of an Infringement resulting from the submission by any Third Party of an abbreviated new drug application under the Hatch-Waxman Act), then ARIAD shall have the right and option to do so at its expense.

-72-

(iv) No Settlement. Neither Party shall settle any Infringement claim or proceeding under Section 8.2.1(a)(ii) or (iii) without the prior written consent of the other Party, which consent shall not be unreasonably withheld, conditioned or delayed.

(b) Right to Representation. Each Party shall have the right to participate and be represented by counsel that it selects, in any legal proceedings or other action instituted under Section 8.2.1(a)(ii) or (iii) by the other Party. If a Party with the right to initiate legal proceedings under Section 8.2.1(a) to eliminate an Infringement lacks standing to do so and the other Party has standing to initiate such legal proceedings, then the Party with the right to initiate legal proceedings under Section 8.2.1(a) may name the other Party as plaintiff in such legal proceedings or may require the Party with standing to initiate such legal proceedings at the expense of the other Party.

(c) Cooperation. In any action, suit or proceeding instituted under this Section 8.2.1, the Parties shall cooperate with and assist each other in all reasonable respects. Upon the reasonable request of the Party instituting such action, suit or proceeding, the other Party shall join such action, suit or proceeding and shall be represented using counsel of its own choice, at the requesting Party’s expense.

(d) Allocation of Proceeds.

(i) Co-Promoted Products. Any amounts recovered by either Party pursuant to actions under Section 8.2.1(a)(ii) or (iii) with respect to any Infringement through the development or commercialization of an mTOR Inhibitor in the U.S. Territory when no U.S. Commercialization Transfer has occurred, whether by settlement or judgment, shall be allocated in the following order: (A) first, to reimburse MERCK and ARIAD for their reasonable out-of-pocket expenses in making such recovery (which amounts shall be allocated pro rata if insufficient to cover the totality of such expenses); and (B) then, to MERCK and ARIAD in the same proportion as their respective Revenue Sharing Percentages.

(ii) Royalty-Bearing Products. Any amounts recovered by either Party pursuant to actions under Sections 8.2.1(a)(ii) or (iii) with respect to any Infringement through the development or commercialization of an mTOR Inhibitor in the ROW Territory or in the U.S. Territory after a U.S. Commercialization Transfer has occurred, whether by settlement or judgment, shall be allocated in the following order: (A) first, to reimburse MERCK and ARIAD for their reasonable out-of-pocket expenses in making such recovery (which amounts shall be allocated pro rata if insufficient to cover the totality of such expenses); and (B) then, to MERCK and ARIAD in the same proportion as MERCK’s historic profits on Net Sales of the Royalty-Bearing Product affected by the Infringement bears to MERCK’s historic royalties paid to ARIAD hereunder in respect of such Net Sales, in each case as determined by the JSC in good faith.

-73-

8.2.2 Defense of Claims. In the event that any action, suit or proceeding is brought against either Party or any Affiliate or Sublicensee of either Party alleging the infringement of the Technology or Patent Rights of a Third Party by reason of or the Development or Commercialization, including, without limitation, the Manufacture, use or sale, of any Product, such Party shall notify the other Party within five (5) days of the earlier of (i) receipt of service of process in such action, suit or proceeding, or (ii) the date such Party becomes aware that such action, suit or proceeding has been instituted and the JSC shall meet as soon as possible to discuss the overall strategy for defense of such matter.

Each Party shall promptly furnish the other Party with a copy of each communication relating to the alleged infringement that is received by such Party including all documents filed in any litigation. In no event shall either Party settle or otherwise resolve any such action, suit or proceeding brought against the other Party or any of its Affiliates or sublicensees without the other Party’s prior written consent.

8.3 Trademark Prosecution and Registration.

8.3.1 The Product Trademark under which each Co-Promoted Product shall be marketed in the U.S. Territory and the ROW Territory shall be determined by the JSC. To the extent possible, the same Product Trademark(s) will be used throughout the Territory. ARIAD shall register the Co-Promotion Trademarks in the U.S. Territory, shall be the exclusive owner of the Co-Promotion Trademarks throughout the world and shall take all such actions as are required to continue and maintain in full force and effect and defend in the U.S Territory the Co-Promotion Trademarks and the registrations thereof, and shall be solely responsible for all expenses incurred in connection therewith, which shall be Commercialization Expenses. The Parties shall market each Co-Promoted Product in the U.S. Territory exclusively under such Product Trademark (all such trademarks being hereinafter referred to as the “Co-Promotion Trademarks”) and under ARIAD’s NDC number, and ARIAD shall grant MERCK a license to use such Co-Promotion Trademarks solely for such Co-Promotion in the U.S Territory and for the sales of Royalty-Bearing Products in the ROW Territory.

8.3.2 MERCK shall be responsible for the filing, prosecution, defense and maintenance before all trademark offices in the ROW Territory of the Product Trademarks applicable to the Product, which may include the Co-Promotion Trademarks and shall be solely responsible for all expenses incurred in connection therewith. MERCK shall consult with ARIAD with respect to all matters relating to the Co-Promotion Trademarks. If MERCK determines to use any trademark in the ROW Territory other than the trademark used in the U.S. Territory, MERCK will license such trademark to ARIAD for use on Product in the U.S. Territory and will not use such trademark for any product other than Product.

-74-

8.3.3 In all Product primary and secondary packages and labels and all marketing and promotional literature, ARIAD shall be presented and described as the Party who developed the Product, and the ARIAD name and logo shall appear in the same in size and prominence as the MERCK name and logo on all Product primary and secondary packages and labels and all marketing and promotional literature used in the Territory, unless prohibited by Applicable Laws.

9. TERM AND TERMINATION

9.1 Term. This Agreement shall commence on the Effective Date and shall continue in full force and effect unless otherwise terminated pursuant to Section 9.2.

Upon the expiration of this Agreement as set forth in this Section 9.1, the license rights granted hereunder shall be converted to perpetual and fully paid-up licenses.

9.2 Termination. Subject to Section 12.1(d), this Agreement may be terminated by either Party as follows:

9.2.1 Unilateral Right to Terminate.

(a) MERCK may terminate this Agreement, effective on any anniversary of the Effective Date on or after the third anniversary of the Effective Date, by providing written notice to ARIAD not less than twelve (12) months prior to such anniversary of the Effective Date.

(b) MERCK may terminate this Agreement (i) at its sole discretion, after meeting with ARIAD as set forth below in Section 9.2.1(c), on written notice to ARIAD in the event that the President of Merck Research Laboratories, following such meeting, determines in good faith that it is not advisable for MERCK to continue Development or Commercialization of the Product for use in a Cancer Indication as a result of a serious safety issue regarding the use of the Product in a Cancer Indication, or (ii) effective upon not less than six (6) months prior written notice to ARIAD, given within ninety (90) days after ARIAD notifies MERCK of the determination in the following clause (x) or the termination in clause (y), in the event that (x) ARIAD has made a final determination that the initial Phase 3 Clinical Trial for a Sarcoma Indication has failed to meet its primary endpoint, or (y) ARIAD terminates such Clinical Trial based on the recommendation of the data monitoring committee of such trial, as specified in the statistical analysis plan for the trial, to terminate the trial early for a reason other than on the basis of significant evidence of efficacy, unless the Product has received Commercialization Regulatory Approval (other than pricing and government reimbursement approval) in the U.S. Territory or the European Union or the Parties have agreed to file a Drug Approval Application for Commercialization Regulatory Approval in a Sarcoma Indication on the basis of results other than meeting the primary endpoint. MERCK agrees that, in determining whether to terminate this Agreement pursuant to Section 9.2.1(b)(ii), it will consider ARIAD’s achievement of any secondary endpoint and/or other efficacy data toward meeting any endpoint. For clarity, MERCK’s right to terminate this Agreement under clause (ii)(x) or (ii)(y) shall not be conditioned on ARIAD giving notice of the determination or termination described in such clauses.

(c) In the event that MERCK believes in good faith that it is not advisable for MERCK to continue Development or Commercialization of the Product as a result of a serious safety issue regarding the use of the Product in a Cancer Indication, MERCK and ARIAD agree to meet promptly following notice of such belief from MERCK to ARIAD in person or by videoconference.

(d) Except to the extent the following is unenforceable under the law of a particular jurisdiction where a patent application with the ARIAD Patent Rights is pending or a patent within the ARIAD Patent Rights is issued, ARIAD may terminate this Agreement immediately upon written notice to MERCK in the event that MERCK or any of its Affiliates or Sublicensees Challenges any ARIAD Patent Right or voluntarily assists a Third Party in initiating a Challenge of any ARIAD Patent Right.

9.2.2 Termination for Breach. Except as set forth herein, (i) either Party may terminate this Agreement, effective immediately upon written notice to the other Party, for a material breach by the other Party of any term of this Agreement that remains uncured sixty (60) days (thirty (30) days in the event that the breach is a failure of a Party to make any payment required hereunder) after the non-breaching Party first gives written notice to the other Party of such breach and its intent to terminate this Agreement if such breach is not cured.

9.2.3 Termination for Insolvency. In the event that either Party makes an assignment for the benefit of creditors, appoints or suffers appointment of a receiver or trustee over all or substantially all of its property, files a petition under any bankruptcy or insolvency act or has any such petition filed against it which is not discharged within sixty (60) days of the filing thereof, then the other Party may terminate this Agreement effective immediately upon written notice to such Party. In connection therewith, all rights and licenses granted under this Agreement are, and shall be deemed to be, for purposes of Section 365(n) of the United States Bankruptcy Code, licenses of rights to “intellectual property” as defined under Section 101(56) of the United States Bankruptcy Code.

In the event of an Acquisition of ARIAD Pharmaceuticals, Inc., MERCK shall have the option, which shall be exercised by written notice to ARIAD Pharmaceuticals, Inc. at least ten (10) days prior to the consummation of the Acquisition if ARIAD Pharmaceuticals, Inc. has given notice thereof to MERCK at least thirty (30) days prior to such consummation or within thirty (30) days after the consummation of the Acquisition if ARIAD Pharmaceuticals, Inc. has not given such notice, (a) to elect to be the Responsible Party for Development the Products throughout the Territory, (b) to require that the [***] (other than [***]) and [***] of Products throughout the Territory, and (c) to require ARIAD to take the actions set forth in clauses (B) through (G) of Section 3.4(b)(ii), but this Agreement shall otherwise not be changed by an Acquisition.

If any provision of this Agreement is or becomes invalid or is ruled invalid by any court of competent jurisdiction or is deemed unenforceable, it is the intention of the Parties that the remainder of the Agreement shall not be affected.

Each Party shall, within fifteen (15) days after the Effective Date (or such later time as the Parties mutually agree in writing) file with the Federal Trade Commission any filing required under the HSR Act, in connection with the transactions contemplated hereby. The Parties shall cooperate with each other to the extent necessary in the preparation of any such filing. Each party shall be responsible for such Party's costs, expenses, and filing fees associated with any such filing. Neither Party shall be required in connection with any filing under the HSR Act to resort to or respond to litigation or to agree to hold separate or divest any business or assets.

EXHIBIT A

Form of Promissory Note

Promissory Note

UP TO

$200,000,000

Date: [date of first Advance]

For value received, ARIAD PHARMACEUTICALS, INC. and ARIAD GENE THERAPEUTICS, INC., both Delaware corporations (collectively “ARIAD”), intending to be legally bound, jointly and severally promise to pay to the order of Merck & Co., Inc., a corporation organized under the laws of New Jersey (“MERCK”), at the time and in the manner set forth herein, the aggregate unpaid principal amount of all advances by MERCK to ARIAD from time to time as provided in Section 1 below (the “Advances”), as such repayable amount may be reduced pursuant to Subsection 3(a) and Section 4 hereof. ARIAD further promises to pay to the order of MERCK interest on the unpaid principal amount hereof from time to time outstanding in accordance with the terms and at the rate per annum set forth below.

This promissory note (the “Promissory Note”) evidences the advances contemplated by and referenced in Section 4.2 of that certain Collaboration Agreement between MERCK and ARIAD dated as of July 11, 2007 (as the same may be amended, supplemented or modified from time to time, the “Collaboration Agreement”), and is entitled to the rights and benefits described therein. Capitalized terms not otherwise defined herein shall have the respective meanings ascribed to them in the Collaboration Agreement.

1. Development Advances.

Subject to the conditions precedent set forth in Section 8 hereof and so long as no Event of Default (defined in Section 9) or an event which, with the giving of notice or the passage of time, or both, would constitute an Event of Default (a "Potential Default") has occurred and is continuing, and no material breach of the Collaboration Agreement by ARIAD has occurred and is continuing, ARIAD may request, and upon such request MERCK will advance up to an aggregate principal amount of Two Hundred Million Dollars ($200,000,000) in the form of Development Cost Advances with respect to ARIAD’s fifty percent (50%) share of Development Costs otherwise payable pursuant to Section 3.12.1 of the Collaboration Agreement, including any reimbursement by ARIAD to MERCK of one-half of certain ROW Development Costs pursuant to the penultimate sentence of Section 3.12.1. If ARIAD desires an Advance under this Section 1, it will give notice to MERCK to such effect setting forth the amount of the Advance (which shall not exceed [***] percent ([***]%) of the total Development Costs incurred by ARIAD and MERCK in the [***]) within the ten (10) day period following the distribution of the written report of the JDC of the calculation of the net amount owed by one Party to the other under Section 3.12.2(a) of the Collaboration Agreement for a given Calendar Quarter. Upon receipt of such notice, MERCK shall not be entitled to receive the amount, if any, otherwise payable by ARIAD to MERCK up to the requested Advance, and to the extent the requested Advance exceeds the amount payable by ARIAD to MERCK, MERCK shall pay to ARIAD such excess within forty-five (45) days of receipt of ARIAD’s request. MERCK shall reflect such non-payment by ARIAD and/or payment by MERCK to ARIAD as an Advance in the Advance Account (as described in Section 5 below), the repayment obligation of which is evidenced by, and subject to the terms of, this Promissory Note. The effective date of each credit to the Advance Account as provided in this Section 1 shall be an “Advance Date.”

-89-

2. Interest Rate. Each Advance shall bear interest on the outstanding principal amount thereof from the Advance Date until paid at a rate per annum (based on a year of 360 days and actual days elapsed) equal to the [***], adjusted quarterly on the first day of each calendar quarter, starting with the rate applicable on the first day of the calendar quarter in which the Advance is made.

3. Payment.

(a) Principal and all accrued and unpaid interest due and payable under this Promissory Note shall be paid by ARIAD through (i) the offset by MERCK of [***] percent ([***]%) of the amount of milestone payments otherwise payable to ARIAD pursuant to Section 4.4 of the Collaboration Agreement and [***] percent ([***]%) of the amount of royalty payments otherwise payable to ARIAD pursuant to Section 4.6 of the Collaboration Agreement, in each case payable after the first Advance Date, and (ii) payment by ARIAD of [***] percent ([***]%) of the ARIAD Revenue Sharing Percentage of Operating Income retained by ARIAD after payment to MERCK of the MERCK Revenue Sharing Percentage of Operating Income (the amounts in clauses (i) and (ii) being referred to herein as the “Payment Sources”). Payments under clause (ii) shall be made with the payments to MERCK of the MERCK Revenue Sharing Percentage. Payments under this Promissory Note will be applied first to accrued interest and then to principal.

(b) In the event that any Advances or accrued interest thereon remain outstanding on the [***] of the first Advance Date (the “Maturity Date”), all such amounts shall automatically become immediately due and payable. MERCK’s obligation to

make Advances to ARIAD shall cease on the Maturity Date.

4. Prepayment. ARIAD may prepay any principal or interest under this Promissory Note at any time without premium or penalty.

5. Advance Account. MERCK shall record in an account (the “Advance Account”) on its books and records the amount of each Advance, the interest rate applicable, all payments or other credits of principal and interest thereon and the principal balance thereof from time to time outstanding. MERCK shall furnish ARIAD with a statement of the Advance Account (the “Statement”), showing all entries therein within thirty (30) days after the end of each calendar quarter. If ARIAD disagrees with MERCK’s Statement, it will notify MERCK in writing and, if ARIAD and MERCK do not resolve the matter within sixty (60) days of ARIAD’s notice, the Parties will resolve the matter in accordance with Section 12.1 of the Collaboration Agreement. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of ARIAD hereunder to pay any amount owing with respect to the Advances, which obligation shall be based on actual Advances, interest charges and payments, and not on the Advance Account, or provide the basis for any claim against MERCK.

-90-

6. [***]. In the event the outstanding amount of the Advances and accrued interest thereon exceeds [***] Dollars ($[***]) as of the end of any calendar quarter, MERCK shall notify ARIAD in writing, and ARIAD may, within thirty (30) days of such notice, make a payment to reduce the amount below [***] dollars ($[***]). If ARIAD does not make such payment, then ARIAD will be deemed, without any further action, [***].

7. Recovery of Costs and Expenses. ARIAD agrees to pay, in addition to all other sums payable hereunder, the reasonable costs and expenses incurred by MERCK in connection with all actions taken to enforce collection of this Promissory Note when due, whether by legal proceedings or otherwise, including without limitation reasonable attorneys’ fees and court costs.

8. Conditions Precedent To The Advances. The obligation of MERCK to make any Advance hereunder is subject to the satisfaction of each of the following conditions precedent:

	(a)	ARIAD shall have paid an aggregate of at least One Hundred Fifty Million Dollars ($150,000,000) in Development Costs.

	(b)	A Product shall have obtained [***]

	(c)	ARIAD shall not have [***]

	(d)	No condition or event shall exist which constitutes an Event of Default or Potential Default, and no material breach of the Collaboration Agreement by ARIAD has occurred and is continuing.

has any such petition filed against it which is not discharged within sixty (60) days of the filing thereof.

10.	Remedies.

(a) Upon the occurrence of an Event of Default described in Subsection 9(a) above which remains uncured for thirty (30) days after written notice from MERCK to ARIAD describing such Event of Default, then this Promissory Note and all sums due hereunder shall automatically become due and payable.

-91-

(b) Upon the occurrence of an Event of Default described in Subsection 9(b) above, all principal and interest under this Promissory Note shall automatically become due and payable.

(c) In addition to the rights and remedies specifically set forth herein, but subject to the limitations on repayment set forth herein, MERCK shall be entitled to such other rights and remedies as are available at law or in equity. The rights and remedies of MERCK hereunder are cumulative and not exclusive of any rights or remedies that MERCK would otherwise have. No single or partial exercise of any such right or remedy by MERCK, and no discontinuance of steps to enforce any such right or remedy, shall preclude any further exercise thereof or of any other right or remedy of MERCK.

11. Payment on Termination of Collaboration Agreement or Upon Acquisition of ARIAD.

(a) Upon the occurrence of an Acquisition of ARIAD Pharmaceuticals, Inc., all principal and interest outstanding on the date of the Acquisition shall become due and payable, and shall be paid within ten (10) days of the consummation of the Acquisition.

ARIAD and Merck & Co., Inc. Announce Global Collaboration to Jointly Develop and Commercialize AP23573 – ARIAD’s Novel mTOR Inhibitor – for Cancer

ARIAD to Host Investor Call Today at 9:00 am (ET)

Cambridge, MA and Whitehouse Station, NJ, July 12, 2007– ARIAD Pharmaceuticals, Inc. (NASDAQ: ARIA) and Merck & Co., Inc. (NYSE: MRK) today announced that they have entered into a global collaboration to jointly develop and commercialize AP23573, ARIAD’s novel mTOR inhibitor, for use in cancer. It is expected that AP23573 will enter into Phase III clinical development for the treatment of metastatic sarcomas beginning this quarter.

The agreement provides for an initial payment of $75 million to ARIAD, up to $452 million more in milestone payments to ARIAD based on the successful development of AP23573 in multiple cancer indications (including $13.5 million for the initiation of the Phase III clinical trial in metastatic sarcomas and $114.5 million for the initiation of other Phase II and Phase III clinical trials), up to $200 million more based on achievement of significant sales thresholds, at least $200 million in estimated contributions by Merck to global development, up to $200 million in interest-bearing repayable development-cost advances from Merck to cover a portion of ARIAD’s share of global-development costs (after ARIAD has paid $150 million in global development costs), and potential commercial returns from profit sharing in the U.S. or royalties paid by Merck outside the U.S.

“We are very excited to be entering into this partnership with ARIAD for the development and potential commercialization of AP23573, as it has the promise to allow us to bring an important new medicine to cancer patients globally. Merck is fully committed to the field of oncology, and this partnership further demonstrates that commitment as we strive to meet unmet medical needs in cancer,” said Vlad Hogenhuis, M.D., General Manager, Oncology, Specialty & Neuroscience Franchise of Merck.

The companies anticipate conducting a broad-based global development program in which clinical trials and biomarker studies will be conducted concurrently in multiple cancer indications. Each party will fund 50% of the cost of global development of AP23573, except that Merck will fund 100% of the cost of ex-U.S. development that is specific to the development or commercialization of AP23573 outside the U.S. In certain circumstances, either party may opt-out of conducting and funding certain late-stage clinical development of AP23573, which would result in changes in development and commercialization responsibilities and compensation arrangements.

Both companies will share overall responsibility for global commercialization and development of AP23573. In the U.S., ARIAD will distribute and sell AP23573 for all cancer indications and book all sales, and ARIAD and Merck will co-promote and will each receive 50% of the income from such sales. Outside the U.S., Merck will distribute, sell and promote AP23573 and book all sales; Merck will pay ARIAD tiered double-digit royalties on such end-market sales of AP23573. On a global basis, ARIAD will be responsible for manufacturing the active pharmaceutical ingredient used in the product, and Merck will be responsible for the formulation and packaging of the finished product (tablets).

In the U.S., ARIAD will have primary responsibility for development of AP23573 in the metastatic sarcoma indication. Merck and ARIAD will have joint responsibility in the U.S. for development of all other cancer indications being pursued. Outside the U.S., Merck will have primary responsibility for development in all cancer indications being pursued.

Stephen Friend, M.D., Ph.D., Executive Vice President and Oncology Franchise Head of Merck said, “mTOR is a validated target for therapeutic intervention in human cancer and resides at a crucial intersection point controlling cell growth and survival of many tumor types. We are delighted to partner with ARIAD to develop and commercialize AP23573 for major unmet medical needs in oncology.”

“This partnership aligns our interests directly with those of Merck – one of the leading global pharmaceutical companies dedicated to developing and commercializing new oncology drugs and with a demonstrated expertise in biomarker development,” said Harvey J. Berger, M.D., Chairman and Chief Executive Officer of ARIAD. “From the beginning, our top corporate priority has been to establish a partnership that will maximize the commercial and clinical potential of our lead oncology product and allow us to realize our vision of becoming a fully integrated oncology company. We implemented a rigorous partnering process that generated substantial interest from multiple companies and ultimately enabled us to select Merck as our partner of choice.”

Richard W. Pascoe, Chief Commercial Officer of ARIAD, added, “We look forward to working closely with our clinical, manufacturing, marketing and sales colleagues from Merck to bring AP23573 to cancer patients as quickly as possible. The structure of this partnership allows the partners to pursue the clinical development of AP23573 in multiple indications concurrently throughout the world.”

About AP23573

ARIAD’s lead product candidate, AP23573, is a novel small-molecule inhibitor of the protein mTOR, a “master switch” in cancer cells. Blocking mTOR creates a starvation-like effect in cancer cells by interfering with cell growth, division, metabolism, and angiogenesis. AP23573 is currently in Phase I and II clinical trials in patients with solid tumors and hematologic cancers. AP23573 has been designated both as a fast-track product and an orphan drug by the U.S. Food and Drug Administration and as an orphan drug by the European Medicines Agency for the treatment of soft-tissue and bone sarcomas. ARIAD is collaborating with Merck & Co., Inc. to develop and commercialize AP23573 in oncology and with Medinol Ltd to develop stents and other medical devices that deliver AP23573 to prevent reblockage at sites of vascular injury following stent-assisted angioplasty.
