Portions of this Exhibit were omitted and have been filed separately with the Secretary of the Commission pursuant to the Company’s application requesting confidential treatment under Rule 24b-2 of the Securities Exchange Act of 1934, as amended.

Japanese corporation (“Chugai”) and its subsidiaries (each, Genentech, Chugai and their subsidiaries a “ROCHE Entity”), shall not be deemed an Affiliate of ROCHE unless ROCHE provides written notice to SYNTA of its desire to include a particular ROCHE Entity as an Affiliate of ROCHE. ROCHE shall have the right to include such ROCHE Entity in whole or in part, i.e. on a legal entity-by-legal entity basis. Notwithstanding such written notice, if any ROCHE Entity does not agree to be bound by the terms and conditions of this Agreement, then such ROCHE Entity shall have none of the rights and obligations of an Affiliate of ROCHE under this Agreement. Notwithstanding the preceding provisions, once an entity ceases to be an Affiliate, then such entity shall, without any further action, cease to have any rights, including license and sublicense rights, under this Agreement that it has by reason of being an Affiliate but shall remain bound by the provisions of Article IX in accordance with its terms.

1.2. “Business Day” means a day that is not a Saturday, Sunday or a day on which banking institutions in Boston, Massachusetts, U.S., or in Basel, Switzerland are authorized by Law to remain closed.

biopharmaceutical companies of comparable size and resources and at the same stage of development as SYNTA, for a product or compound which is of similar market potential and at a similar stage of development or commercialization, as applicable, taking into account the existence of other competitive products in the market place or under development, the proprietary position of the product, the regulatory structure involved, the anticipated profitability of the product (without regard to any amounts paid or payable with respect to Licensed Products under this Agreement) and other relevant factors. It is also to be appreciated that a major global pharmaceutical company does not always seek to market products in every country or seek regulatory approval for every potential Indication, but that ROCHE shall undertake to commercialize Licensed Products in the Major Markets absent a compelling reason not to do so. It is understood that such products’ potential may change from time to time based upon changing scientific, business and marketing and return on investment considerations. As a result, the exercise of diligence by ROCHE is to be determined by judging ROCHE’s commercially reasonable efforts taken as a whole.

1.50. “Net Sales” means the amount calculated by subtracting from the amount of Adjusted Gross Sales (as defined below) a lump sum deduction of (1) [] percent ([]%) of

Portions of this Exhibit were omitted and have been filed separately with the Secretary of the Commission pursuant to the Company’s application requesting confidential treatment under Rule 24b-2 of the Securities Exchange Act of 1934, as amended.

Adjusted Gross Sales, with respect to Net Sales in the United States, (2) [] percent ([]%) of Adjusted Gross Sales, with respect to Net Sales in the Major Markets (other than the U.S.) and Canada, and (3) [] percent ([]%) of Adjusted Gross Sales, with respect to Net Sales in all territories other than those set forth in clause (1) and (2) above, in lieu of all deductions corresponding to charges allocable to the sale of Licensed Product and paid by ROCHE but which are not accounted for by ROCHE, its Affiliates, ROCHE Entities and Sublicensees on a product-by-product basis in the calculation of Adjusted Gross Sales (e.g., outward freights, postage charges, transportation insurance, packaging materials for dispatch of goods, custom duties, bad debt expense).

For purposes of this definition of “Net Sales”, “Adjusted Gross Sales” shall mean the amount of gross sales of Licensed Product invoiced by ROCHE, its Affiliates, ROCHE Entities and its Sublicensees to Third Parties less deductions (which deductions shall in all cases be as consistently applied by ROCHE to its products) for:

(a) Governmental price reductions and changes to reserves for governmental price reductions, such as rebates to managed care organizations or social and welfare systems, charge backs or reserves for chargebacks, cash sales incentives (but only to the extent it is a sales related deduction which is accounted for within ROCHE on a product-by-product basis), government mandated rebates and similar types of rebates (e.g., Pharmaceutical Price Regulation Scheme, Medicaid, clawback schemes and any other similar such scheme);

(b) Contract pricing chargebacks and changes to reserves of contract pricing chargebacks, such as periodic charges of wholesalers and chargebacks for price capping programs;

(c) Customer rebates and changes to reserves of customer rebates, such as volume (quantity) discounts or price discounts;

(d) Returns and return reserves, including allowances actually given for spoiled, damaged, out-dated, rejected, returned Licensed Product sold, withdrawals and recalls;

(e) Cash discounts; and

(f) Taxes, such as value added or sales taxes, government mandated exceptional taxes and other taxes directly linked to the gross sales amount (but excluding income or capital gains taxes).

For the avoidance of doubt, the “Adjusted Gross Sales” shall be determined on a Licensed Product-by-Licensed Product basis using the same methodology as ROCHE consistently uses to recognize sales in its financial reporting, which is in accordance with the then-used International Financial Reporting Standards (IFRS), and is reviewed and approved by ROCHE’s external auditors, it being understood that if the amount of any of the reserves accounted for as a deduction in the definition of “Adjusted Gross Sales” above exceeds the actual amount for which the reserve was established, the amount of such excess shall be treated as Net Sales.

Notwithstanding the foregoing, amounts received by ROCHE, its Affiliates, ROCHE Entities and Sublicensees for the sale of Licensed Product among ROCHE, its Affiliates, ROCHE Entities or Sublicensees for resale shall not be included in the computation of Adjusted Gross Sales or Net Sales.

If a Licensed Product is sold as part of a Combination Product (as defined below), the Net Sales of the Licensed Product, for the purposes of determining royalties based on Net Sales, shall be determined country-by-country by multiplying the Net Sales of the Combination Product (as determined using the standard Net Sales definition), during the applicable reporting period, by the fraction, A/(A+B), where A is the average sale price of the Licensed Product when sold separately in similar quantities in finished form and B is the average sales price of the other compounds having independent therapeutic activity included in the Combination Product when sold separately in similar quantities in finished form, in each case in the same country as the Combination Product during the applicable reporting period or, if sales of both the Licensed Product and the other compounds having independent therapeutic activity did not occur in such period, then in the most recent reporting period in which sales of both occurred in the same country as the Combination Product. If such average sale price cannot be determined for both the Licensed Product and all other compounds having independent therapeutic activity included in the Combination Product, Net Sales of the Licensed Product for the purposes of determining royalty payments shall be calculated by multiplying the Net Sales of the Combination Product by the fraction of C/(C+D) where C is the fair market value of the Licensed Product and D is the fair market value of all other compounds having independent therapeutic activity included in the Combination Product. In such event, ROCHE shall in good faith make a determination of the respective fair market values of the Licensed Product and all other compounds having independent therapeutic activity included in the Combination Product, and shall notify SYNTA of such determination and provide SYNTA with data to support such determination. SYNTA shall have the right to review such determination and supporting data, and to notify ROCHE if it disagrees with such determination. If SYNTA does not agree with such determination and if the Parties are unable to agree in good faith as to such respective fair market values, then such matter shall be resolved in accordance with Section 13.2.

As used in this Agreement, “Combination Product” means any Licensed Product containing one or more additional active pharmaceutical compounds having independent therapeutic activity other than a Licensed Compound.

1.51. “Party” or “Parties” means SYNTA or ROCHE, as the context requires.

1.52. “Patent Rights” means all rights under any patent or patent application, in any country or jurisdiction in the Territory, including any patents issuing on such patent application and any substitution, extension or supplementary protection, certificate, reissue, reexamination, renewal, division, continuation or continuation-in-part of any of the foregoing.

ARTICLE II -COLLABORATION

2.1. Overview. The primary objective of the collaboration between the Parties will be to identify and select Collaboration Compounds under the Research Program that are suitable for further Research and, subject to Section 2.4, to advance the Development of such Collaboration Compounds as Licensed Compounds and the Commercialization of related Licensed Products in the Field, as further described below.

2.2. Commercially Reasonable Efforts. Each Party shall use Commercially Reasonable Efforts to conduct the activities which are assigned to such Party under the Research Plan or any Development Plan; provided, however, that neither Party guarantees the success of the Research Program or any individual Research, Development or Manufacturing activity undertaken under the Research Plan or Development Plan. Without limiting ROCHE’s obligations pursuant to this Section 2.2, ROCHE shall use Commercially Reasonable Efforts to (a) Develop, at any given time, at least one Licensed Compound, and (b) seek Regulatory Approval for at least one Licensed Compound and then Commercialize each such approved Licensed Product for each approved Indication in the Field in the Territory.

2.3. Research Program.

2.3.1. Research Term. The initial term of the Research Program shall commence on January 1, 2009 and end on the second (2nd) anniversary thereof, unless (a) earlier terminated hereunder, or (b) extended by mutual agreement of the Parties for additional one (1) year term(s), in which case the Parties shall agree upon appropriate FTE commitment levels, budget adjustments and other necessary amendments to the Research Plan (such initial two (2) year term, together with any extension, the “Research Term”). The SYNTA FTE Rate for any such extension shall be determined as set forth in Section 1.29.

2.3.2. Collaboration Compounds. The Research Program shall be conducted on Collaboration Compounds; provided, however, that if, in the course of the Research Program, it

is determined that any such compound is not a CRAC Channel Inhibitor, such compound shall no longer be considered a Collaboration Compound, and provided, further, that any Collaboration Compound that is not a Licensed Compound as of the end of the Research Term shall revert to the Controlling Party (including all rights thereto and to any Confidential Information with respect to such Collaboration Compound which had been disclosed by such Controlling Party) and shall no longer be deemed a Collaboration Compound for purposes of this Agreement. It is the intent of the Parties that the initial Collaboration Compounds with respect to which Research will be conducted under the Research Program will be the Collaboration Compounds Controlled and identified by SYNTA hereunder. Compounds Controlled by ROCHE will be included as a Collaboration Compound with respect to which Research will be conducted under the Research Program and for other purposes of this Agreement only if mutually agreed by the Parties. The goal of the Research Program is for one or more Licensed Compounds to be approved for advancement into Development under Section 2.3.4.

2.3.3. Research Plan. The initial plan for the first two (2) Contract Years of the Research Program is attached hereto as Exhibit B (as may be amended from time to time upon mutual agreement of the Parties, the “Research Plan”). The Parties agree and acknowledge that this Research Plan reflects, as of the Execution Date, SYNTA’s good faith estimates of Research activities and the timing, internal costs, and external costs associated with such activities, all of which could be subject to change. During the Research Term, SYNTA and ROCHE shall prepare an updated Research Plan for the third and each subsequent Contract Year, if applicable, at least [] ([]) days prior to the start of each such Contract Year. The Research Plan shall be consistent with the terms and conditions of this Agreement and shall be subject to review and approval by the JRDC and the JSC. The Research Plan shall specify, among other things, (a) key objectives, (b) Research and related Manufacturing activities to be performed up to nomination of a Licensed Compound for Development, (c) the number and types of FTEs to be assigned to specific activities and the Party supplying such FTEs, (d) costs and expenses for services to be provided by Third Parties, (e) to the extent known in advance, the academic collaborations and subcontractor arrangements anticipated for the applicable Contract Year, and (f) the budget for the applicable Contract Year. With respect to the first (2) Contract Years, all FTEs specified in the Research Plan shall be supplied by SYNTA. For the sake of clarity, neither the initial Research Plan attached hereto, nor any subsequent Research Plan once agreed by the Parties, may be amended except by mutual agreement of the Parties.

2.3.4. Licensed Compound Nomination.

(a) Either Party may nominate to the JDRC, for approval by the JSC, a Licensed Compound for advancement into Development leading up to a GLP Toxicology Study. Upon request by a Party, the other Party shall provide relevant available information and study results to support such nomination. If no Licensed Compound is approved for advancement into Development during the Research Term or within [] ([])[***] after expiration of the Research Term, SYNTA shall have the option, not the obligation, to perform the Development activities described in Section 2.4.1.

Portions of this Exhibit were omitted and have been filed separately with the Secretary of the Commission pursuant to the Company’s application requesting confidential treatment under Rule 24b-2 of the Securities Exchange Act of 1934, as amended.

(b) ROCHE shall have no right to Develop or Commercialize any Licensed Compound (other than any activities that may be assigned to ROCHE under the Research Plan) unless and until such Licensed Compound has been nominated by the JRDC, and approved by the JSC, for advancement into Development hereunder.

2.4. Development. The Parties shall pursue the Development of at least one Licensed Compound in accordance with a Development Plan and the remainder of this Article II, including seeking to pursue the Initiation of a GLP Toxicology Study. For clarity, for each Licensed Compound approved by the JSC for advancement into Development under Section 2.3.4(a), a set of Development activities will be conducted prior to the Initiation of a GLP Toxicology Study, as exemplified in Exhibit C. As of the Execution Date, the Parties agree that [***] is anticipated to be the First Licensed Compound.

2.4.1. First Licensed Compound. For the relevant First Licensed Compound, SYNTA (itself or through an Affiliate or a Third Party) shall, in accordance with the Development Plans: conduct pre-IND Xxxxxxxxxxx, Xxxxx 0 Clinical Trials, and other nonclinical Development activities that are typically performed during each of the foregoing Development stages, and shall have the right, at SYNTA’s option, to conduct a Phase 2a Clinical Trial for an Indication other than rheumatoid arthritis, provided, that such Indication is part of the Development Plan.

2.4.2. Other Licensed Compounds.

2.5. Development Costs.

2.5.1. General. ROCHE shall pay its own Development expenses in carrying out each Development Plan, and shall pay SYNTA for all Development Costs incurred pursuant to each Development Plan and the applicable Budget as set forth below.

2.5.2. Audit Rights. ROCHE shall have the right to audit SYNTA to verify all of SYNTA’s Development Costs incurred pursuant to a Development Plan and the Budget.

(a) SYNTA shall keep, and shall require its Affiliates to keep, for [] ([]) years, full, true and accurate books of account containing all particulars that may be necessary for the purpose of calculating all Development Costs under this Agreement. Such books of accounts shall be kept at SYNTA’s or the relevant Affiliate’s principal place of business. At the expense of ROCHE, ROCHE has the right to engage an independent, certified public accountant mutually acceptable to both Parties to perform, on behalf of ROCHE, an audit of such books and records of SYNTA and its Affiliates, that are deemed necessary by such accountant to report on Development Costs for the period or periods requested by ROCHE and the correctness of any report or payments made under this Agreement. Such accountant shall not have the authority to interpret this Agreement.

(b) Upon timely request and at least [] ([]) days prior written notice from ROCHE, such audit shall be conducted, during regular business hours in such a manner as to not unnecessarily interfere with SYNTA’s or its Affiliates’ normal business activities, and shall be limited to results in the [] ([]) calendar years prior to audit notification.

(c) Such audit shall not be performed more frequently than once per calendar year nor more frequently than once with respect to records covering any specific period of time.

(d) All information, data and documents herein referred to shall be used only for the purpose of verifying Development Costs, shall be treated as SYNTA Confidential Information subject to the obligations of this Agreement and need neither be retained more than the longer of one (1) year after completion of an audit hereof, if an audit has been requested; nor more than [] ([]) years from the end of the calendar year to which each shall pertain; nor more than [] ([]) [***] after the date of termination of this Agreement.

(e) The final audit report shall be shared by ROCHE and SYNTA.

(f) If the audit reveals an underpayment, ROCHE shall reimburse SYNTA for the amount of the underpayment within [] ([]) days with interest as set forth in Section 7.7.2. If the audit reveals an overpayment, ROCHE shall have the right to credit the amount of such overpayment against the next payment payable to SYNTA hereunder. SYNTA shall pay for the audit costs if the audit reveals that an overpayment of ROCHE exceeds [] percent ([]%).

(g) The failure of ROCHE to request verification of any Actual Costs within the period during which the corresponding records must be maintained under Section 2.5.2(d) will be deemed acceptance of the Actual Cost payments and reports with respect thereto.

2.5.3. Budget. It is agreed between the Parties that for the calendar year 2009, the Budget for payment to SYNTA of its Development Costs under the Development Plan as of the Execution Date is [] dollars ($[]). On or before October 1, 2009 and not later than October 1 of each subsequent calendar year during the Term, the JSC shall approve annual Budgets for Development Costs scheduled for the following year; such annual Budgets to be consistent with the Development Plan(s). Upon approval, the annual Budget shall be the Budget then in effect.

2.5.4. Payments to SYNTA; Reconciliation. ROCHE shall pay to SYNTA the amount set forth as SYNTA’s Development Costs under the Budget for each Calendar Quarter on or before the later of (a) the first day of such Calendar Quarter or (b) [] ([]) days after receipt of an invoice from SYNTA with respect to such Development Costs. Within [] ([]) days following the end of each such Calendar Quarter, SYNTA shall provide an accounting to ROCHE of the actually incurred Development Costs during such Calendar Quarter (the “Actual Costs”). Following the reporting by SYNTA of Actual Costs for each Calendar Quarter, the Parties shall reconcile any difference between the amounts paid by ROCHE to SYNTA for Development Costs and SYNTA’s Actual Costs for such Calendar Quarter. If the amounts paid by ROCHE to SYNTA for Development Costs exceed SYNTA’s Actual Costs during such Calendar Quarter, then the amount of such excess shall be credited to ROCHE against the next payment payable to SYNTA hereunder. If SYNTA’s Actual Costs during the Calendar Quarter exceeds by less than [] percent ([]%) the amount paid by ROCHE for Development Costs during such Calendar Quarter (the amount of such excess, the “Covered Excess Amount”), then ROCHE shall pay the Covered Excess Amount to SYNTA as a supplemental payment. If SYNTA’s Actual Costs during the Calendar Quarter exceeds by [***]

percent ([]%) or more the amount paid by ROCHE for Development Costs during such Calendar Quarter, then (y) ROCHE shall pay the Covered Excess Amount to SYNTA as a supplemental payment and (z) with respect to the amount of such excess over and above the Covered Excess Amount (the “Uncovered Excess Amount”), ROCHE shall pay the Uncovered Excess Amount but only if the JSC approves such Uncovered Excess Amount. ROCHE shall pay SYNTA any Covered Excess Amount and, to the extent payable by ROCHE hereunder, any Uncovered Excess Amount within [] ([]) days after receipt of an invoice from SYNTA therefor, subject to the cap of $[] for calendar year 2009. For purposes of clarity, ROCHE’s obligation under this Section 2.5.4 to pay SYNTA for Development Costs shall be separate from, and in addition to, ROCHE’s obligation under Section 7.2 to pay SYNTA for internal and external Research costs incurred by SYNTA under the Research Plan.

2.6. Manufacturing.

4.2. Communications with Regulatory Authorities.

4.2.1. ROCHE shall keep SYNTA informed on an ongoing basis through the JRDC or JSC regarding its (or its Affiliate’s or Sublicensee’s) regulatory strategy, planned regulatory submissions and material communications with Regulatory Authorities in Major Markets with respect to all Licensed Compounds and Licensed Products. If, and to the extent SYNTA is responsible for the filing of the IND and other regulatory filings with respect to a Licensed Compound pursuant to Section 4.1.1, then the obligations of ROCHE set forth in Sections 4.2.1 above shall apply to SYNTA, mutatis mutandis until such time as Development responsibility is transferred to ROCHE pursuant to Section 2.7.1, except that such obligations shall apply with regard to all countries of the Territory as opposed to just the Major Markets.

4.2.2. In addition, ROCHE shall provide SYNTA with reasonable advance notice of any material meeting or substantive telephone conference with the FDA, MHLW or EMEA relating to any Licensed Compound or Licensed Product. SYNTA shall have the right to attend and observe (but not participate actively in) any such material meeting or material conference call with the FDA regarding any Licensed Compound or Licensed Product under Development by ROCHE (or by its Affiliates or Sublicensees). In addition, ROCHE shall promptly provide SYNTA with a copy of all material correspondence that ROCHE (or its Affiliate or Sublicensee) receives from, or submits to, any Regulatory Authority in the Major Markets (including contact reports concerning conversations or substantive meetings, contact reports of all Regulatory Authority interactions concerning conversations or substantive meetings, all IND annual reports (including any equivalent filings outside the US), and cover letters of all agency submissions, it being understood that SYNTA may request, and shall then receive, copies of all attachments to any such cover letters) relating to any Licensed Compound or Licensed Product. ROCHE shall also provide SYNTA with any meeting minutes that reflect material communications with any Regulatory Authority in the Major Markets regarding a Licensed Compound or Licensed Product.

4.2.3. Notwithstanding the foregoing, if, and to the extent SYNTA is responsible for the filing of the IND and other regulatory filings with respect to a Licensed Compound pursuant to Section 4.1.1, the rights and obligations of ROCHE set forth in Sections 4.2.2 above shall apply to SYNTA, mutatis mutandis until such time as Development responsibility is transferred to ROCHE pursuant to Section 2.7.1.

4.3. Pharmacovigilance. The Parties agree that they will execute a separate pharmacovigilance agreement, if legally required, specifying the procedures and timeframes for compliance with the applicable Laws pertaining to safety reporting of any Licensed Compound or Licensed Product and its related activities.

ARTICLE V - COMMERCIALIZATION; CO-PROMOTION

5.1. General. Subject to SYNTA’s Co-promotion Option and the other terms and conditions of this Agreement, ROCHE will have sole responsibility for the Commercialization of Licensed Products in the Field in the Territory, including all costs and expenses relating thereto.

5.2. Commercialization Summary. With respect to each Licensed Product Developed pursuant to this Agreement, commencing with the calendar year in which an application for Regulatory Approval is first filed with respect to each such Licensed Product, and for each subsequent calendar year during next [] ([]) years, ROCHE shall provide SYNTA, through the JSC (if the JSC remains in place), for its review and comment, a written summary of the Commercialization activities conducted in the Major Markets other than Japan during the prior year and planned to be conducted in such upcoming year by or on behalf of ROCHE and its Affiliates and Sublicensees with respect to such Licensed Product in such countries. ROCHE shall consider in good faith the reasonable suggestions and comments of SYNTA with respect to such summary.

5.3. Co-promotion. Upon ROCHE’s decision to file an application for Regulatory Approval in the United States of a Licensed Product for any Indication other than rheumatoid arthritis (which decision is expected to occur at least [] ([]) [] prior to filing any such application) (such decision, the “Commercialization Decision”), ROCHE shall notify SYNTA in writing within twenty (20) Business Days thereof. For clarity, such obligation of ROCHE to notify SYNTA of any Commercialization Decision shall apply to all Licensed Products with respect to which the Commercialization Decision is made. On a Licensed Product-by-Licensed Product basis, SYNTA shall have the right to participate in the Co-promotion of any Licensed Product in the United States for the applicable Indication (the “Co-promotion Option”). SYNTA may exercise its Co-promotion Option by providing written notice to ROCHE within [] ([]) [] after receipt of ROCHE’s Commercialization Decision notice, in which event the minimum terms set forth on Schedule 5.3 shall apply. If SYNTA does not exercise its Co-promotion Option within such [] ([]) [***] period, then SYNTA shall have no further right to elect to participate in the Co-promotion of such Licensed Product in the United States for the applicable Indication; provided, however, that the Co-promotion Option shall continue to apply to any and all subsequent Licensed Products, and the failure of SYNTA to exercise its Co-promotion Option with respect to any Licensed Product for any Indication shall not prevent or waive SYNTA’s right to exercise its Co-promotion Option with respect to such Licensed Product for any other Indication or with respect to any other Licensed Product.

27 5.4. Labeling. In the event of SYNTA’s Co-promotion of any Licensed Product in accordance with Section 5.3, ROCHE shall include on all secondary packaging, literature, labels and other printed matter for Licensed Products used in clinical Development or in Commercialization, to the extent permitted by applicable Law, the SYNTA name and logo so as to acknowledge that the Licensed Products were developed under license from and together with SYNTA.

6.7. Section 365(n) of the Bankruptcy Code. All rights and licenses granted pursuant to any section of this Agreement, including pursuant to Sections 6.1, 6.2 and 6.3, are rights and licenses to “intellectual property” (as defined in Section 101(35A) of title 11 of the United States Code (the “Bankruptcy Code”)). Each Party shall retain and may fully exercise all of its rights and elections under the Bankruptcy Code.

ARTICLE VII -FINANCIAL PROVISION; AUDIT RIGHTS

7.2.1. FTE Funding. In order to fund SYNTA’s Research activities hereunder performed by SYNTA FTEs, ROCHE shall pay to SYNTA a total of nine million dollars ($9,000,000), to be paid in eight (8) payments, each in the amount of one million one hundred twenty-five thousand dollars ($1,125,000), each such payment due and payable [] ([]) days after the later of (a) the first day of each Calendar Quarter, starting January 1, 2009, and (b) receipt by ROCHE of an invoice for such sum.

Roche shall reimburse SYNTA such amount up to the limits set forth in this paragraph 7.2.2, within [] ([]) days after receipt of such accounting and an invoice for such amount. Any amounts in excess of the limits in a given year shall be the responsibility of SYNTA.

7.3. Co-promotion Activities. If SYNTA exercises its right to participate in the Co-promotion of one or more Licensed Products in the United States pursuant to Section 5.3, then ROCHE shall reimburse SYNTA for costs of such Co-promotion, as set forth on Schedule 5.3.

		Payment (US$ millions)
Development Event		First Indication to Achieve the Relevant Development Event		Second Indication to Achieve the Relevant Development Event		Third Indication to Achieve the Relevant Development Event
(a)	Initiation of GLP Toxicology Study	$	[***]	n/a		n/a
(b)	Filing of an IND anywhere in the world	$	[***]	n/a		n/a
(c)	Initiation of a Phase 2a Clinical Trial	$	[***]	$	[***]	$	[***]
(d)	Initiation of a Phase 2b Clinical Trial	$	[***]	$	[***]	$	[***]
(e)	Initiation of a Phase 3 Clinical Trial	$	[***]	$	[***]	$	[***]
(f)	Filing of an NDA in the United States	$	[***]	$	[***]	$	[***]
(g)	Filing of an NDA in any Major EU Country (or with the EMEA)	$	[***]	$	[***]	$	[***]
(h)	Filing of an NDA in Japan	$	[***]	$	[***]	$	[***]
(i)	Regulatory Approval in the United States	$	[***]	$	[***]	$	[***]
(j)	Regulatory Approval in a Major EU Country (or by the EMEA)	$	[***]	$	[***]	$	[***]
(k)	Regulatory Approval in Japan	$	[***]	$	[***]	$	[***]

Each of the event payment amounts set forth in the table above shall be paid (i) as set forth above upon the first occurrence of such event, and (ii) at fifty percent (50%) of the amount

set forth above with respect to each of the second and third occurrences of such event by another Licensed Product.

For the sake of clarity (A) the same Indication need not achieve each development event in a column (Example 1 below); (B) the same Licensed Product need not achieve each development event in a row (Example 2 below); and (C) no payment shall be made with respect to the occurrence of an event for which a payment had been made with respect to the prior occurrence of the same event with the same Licensed Product for the same Indication (Example 3 below). By way of example,

· Example 1: If the first Initiation of a Phase 2a Clinical Trial is for Licensed Product A in Indication rheumatoid arthritis, $[***] will be due (row (c), first column times 100%). If the second Initiation of a Phase 2a Clinical Trial is for Licensed Product A in Indication asthma, $[***] will be due (row (c), second column times 100%). If the third Initiation of a Phase 2a Clinical Trial is for Licensed Product B in Indication asthma, $[***] will be due (row (c), first column times 50%).

· Example 2: If the first Initiation of a Phase 2a Clinical Trial is for Licensed Product A in Indication rheumatoid arthritis, $[***] will be due (row (c), first column times 100%). If the second Initiation of a Phase 2a Clinical Trial is for Licensed Product B in Indication rheumatoid arthritis, $[***] will be due (row (c), first column times 50%). If the third Initiation of a Phase 2a Clinical Trial is for Licensed Product B in Indication asthma, $[***] will be due (row (c), second column times 100%).

· Example 3: If the first Initiation of a Phase 2a Clinical Trial is for Licensed Product A in Indication rheumatoid arthritis, $[***] will be due (row (c), first column times 100%). If the second (or subsequent) Initiation of a Phase 2a Clinical Trial is for Licensed Product A in Indication rheumatoid arthritis, no milestone payment shall be due with respect to such Initiation.

On a Licensed Product-by-Licensed Product basis, the achievement of a development event in any of rows (f) through (k) shall result in a simultaneous obligation to pay all payments in rows (a) through (e) that had not been previously paid and which are in the same column as the payment then to be made. On a Licensed Product-by-Licensed Product basis, and a country-by-country or regional basis, the achievement of a development event in any of rows (i) through (k) shall result in a simultaneous obligation to pay the relevant earlier milestone in rows (f) through (h), as applicable, that had not previously been paid and which are in the same column as the payment then to be made.

Upon achievement by or on behalf of ROCHE, its Affiliates or Sublicensees of any of the foregoing development events, ROCHE shall promptly (but in no event more than ten (10) Business Days following achievement thereof) notify SYNTA and shall pay to SYNTA all

corresponding development event payments within [***] ([***]) days after occurrence of the applicable event and receipt of an invoice from SYNTA.

If SYNTA is the Party that achieves any of the development events set forth above, SYNTA shall provide notice to ROCHE promptly upon achievement of each such development event and shall deliver to ROCHE an invoice for such event. ROCHE shall pay the applicable development event payment within [***] ([***]) days of receipt of invoice therefor.

7.5. Sales Event Payments. In addition to all other amounts payable under this Agreement, ROCHE shall make the following non-refundable, non-creditable payments to SYNTA based on aggregate worldwide annual (on a calendar year basis) Net Sales, on a Licensed Product-by-Licensed Product basis for up to three (3) Licensed Products, upon the first achievement of the events set forth below by each of such Licensed Products:

Sales Event		Payments (in US$ millions)
(a)	Aggregate worldwide annual Net Sales of such Licensed Product reaches or exceeds $[*] (> $[*])	$	[***]
(b)	Aggregate worldwide annual Net Sales of such Licensed Product reaches or exceeds $[*] (> $[*])	$	[***]
(c)	Aggregate worldwide annual Net Sales of such Licensed Product reaches or exceeds $[*] (> $[*])	$	[***]
(d)	Aggregate worldwide annual Net Sales of such Licensed Product reaches or exceeds $[*] (> $[*])	$	[***]

For purposes of clarity, the sales event payments set forth in this Section 7.5 shall be paid only once for each Licensed Product, upon the first achievement of the applicable sales event.

Upon achievement by ROCHE, its Affiliates, Sublicensees or ROCHE Entities of any of the foregoing sales events, ROCHE shall promptly (but in no event more than thirty (30) days following achievement thereof) notify SYNTA and shall pay to SYNTA the corresponding sales event payment within [***] ([***]) days after occurrence of the applicable event and receipt of an invoice from SYNTA.

7.6. Licensed Product Royalties.

7.6.1. ROCHE shall pay to SYNTA royalties on the aggregate worldwide annual (on a calendar year basis) Net Sales of each Licensed Product in the Territory, on a Licensed Product-by-Licensed Product basis, as follows:

Portions of this Exhibit were omitted and have been filed separately with the Secretary of the Commission pursuant to the Company’s application requesting confidential treatment under Rule 24b-2 of the Securities Exchange Act of 1934, as amended.

Aggregate Worldwide Annual Net Sales of Licensed Product		Royalty Rate
(i)	First $[***]	[***]	%
(ii)	Portion above $[*] and up to and including $[*]	[***]	%
(iii)	Portion above $[*] and up to and including $[*]	[***]	%
(iv)	Portion above $[***]	[***]	%

7.6.2. Applicability of Royalty Rates to Net Sales in the Territory. Royalties payable pursuant to this Section 7.6 shall be paid at the rate applicable to the portion of Net Sales within each of the Net Sales levels during the applicable calendar year for such Licensed Product. For example, if, during a calendar year, aggregate worldwide annual Net Sales of a particular Licensed Product were equal to $[], then the royalties payable by ROCHE would be calculated by adding (i) the royalties with respect to the first $[] at the first-level percentage of [] percent ([]%) ($[]), and (ii) the royalties with respect to the next $[] at the second-level percentage of [] percent ([]%) ($[]), for a total royalty of $[].

7.6.3. Royalty Term and Adjustments.

(a) ROCHE’s royalty obligations to SYNTA pursuant to this Section 7.6 shall commence on a country-by-country and Licensed Product-by-Licensed Product basis on the First Commercial Sale in such country of such Licensed Product and shall expire on a country-by-country basis and Licensed Product-by-Licensed Product basis on the later of: (A) the expiration of the last Valid Claim of the SYNTA Patent Rights, ROCHE Patent Rights and Joint Patent Rights Covering such Licensed Product in such country, or (B) the [] ([]) anniversary of the date of the First Commercial Sale of such Licensed Product in such country by or on behalf of ROCHE or any of its Affiliates or Sublicensees to a Third Party who is not a Sublicensee (the “Royalty Term”). Thereafter, the licenses granted to ROCHE shall be fully paid-up, royalty-free and non-exclusive with respect to such Licensed Product in such country, on a Licensed Product-by-Licensed Product and country-by-country basis.

(b) Notwithstanding the foregoing, the royalty rate applicable to such Licensed Product sold in any country in the Territory shall be reduced to [] percent ([]%) of the rate otherwise payable pursuant to Section 7.6.1 above during any portion of the Royalty Term when there is no Valid Claim of the SYNTA Patent Rights, ROCHE Patent Rights or Joint Patent Rights Covering such Licensed Product in such country; provided that such reduction shall not apply if the Licensed Product is entitled to Marketing Exclusivity in such country and there is no Generic Product on the market in such country.

7.6.4. Royalty Adjustment in Case of Generic Competition. If, during a given Calendar Quarter there is Generic Competition with respect to a particular Licensed Product in a country of the Territory, then the royalties on Net Sales of the affected Licensed Product payable

pursuant to this Section 7.6 in such country for such Calendar Quarter shall be reduced by [] percent ([]%) of the amounts otherwise payable pursuant to Section 7.6.1. For clarity, the determination of whether there is Generic Competition with respect to a particular Licensed Product in a country and, if so, the market share of such Generic Product(s) in such country, shall be made on a Calendar Quarter-by-Calendar Quarter basis. For example, if with respect to a particular Licensed Product in a country there is Generic Competition with respect to such Licensed Product in a Calendar Quarter then the applicable royalty reductions set forth in this Section 7.6.4 shall apply for such Calendar Quarter, and if, with respect to the same Licensed Product in the same country there is no Generic Competition during any subsequent Calendar Quarter, then the royalty reductions set forth in this Section 7.6.4 shall not be applicable in any such subsequent Calendar Quarter. Notwithstanding any of the foregoing, if both deductions under Section 7.6.3 and this Section 7.6.4 apply for a Licensed Product in a given country, then ROCHE may apply only one of the two deductions for such Licensed Product in such country.

7.6.5. Third Party Payments. ROCHE shall be responsible for obtaining, and paying or having paid any consideration owed to any Third Party to license or otherwise secure and maintain, Third Party Patent Rights necessary to manufacture or sell Licensed Products in the Field in the Territory. ROCHE shall have the right to deduct a maximum of [] percent ([]%) of such royalties actually paid to such Third Party with respect to such license to permit the manufacture or sale of Licensed Product(s) in the Field in a country(ies), from royalty payments otherwise due and payable by ROCHE to SYNTA under this Agreement with respect to such Licensed Product(s) in such country(ies), on a Licensed Product-by-Licensed Product and country-by-country basis; provided, however, that (i) in no event shall the deduction permitted by this Section 7.6.5 reduce the royalties payable to SYNTA with respect to any such Licensed Product(s) in such country(ies) to less than [] percent ([]%) of the royalties otherwise due after any deduction pursuant to Section 7.6.3 or 7.6.4.

7.6.6. Limitation on Aggregate Deduction. In no event shall the deductions permitted by Sections 7.6.3, 7.6.4 and this 7.6.5, in the aggregate, reduce the royalties payable to SYNTA with respect to any such Licensed Product(s) in such country(ies) to less than [] percent ([]%) of the royalties otherwise due for such Licensed Product(s) in such country(ies) pursuant to Section 7.6.1, on a Licensed Product-by-Licensed Product and country-by-country basis.

7.7. Accounting and Reporting.

7.7.1. Timing of Payments. ROCHE shall calculate royalties on Net Sales quarterly as of March 31, June 30, September 30 and December 31 (each being the last day of an “Accounting Period”) and shall pay royalties on Net Sales within [] ([]) days after the end of each Accounting Period in which such Net Sales occur.

7.7.2. Late Payment. Any payment under this Agreement that is not paid on or before the date such payment is due shall bear interest, to the extent permitted by applicable Law, at [***] above the average one-month London Interbank Offered Rate (LIBOR), as reported by Reuters for time to time, calculated on the number of days such payment is overdue. In addition,

ROCHE shall reimburse SYNTA for all costs and expenses, including attorneys’ fees and legal expenses, incurred in the collection of late payments, provided that the foregoing shall not apply with respect to payments disputed in good faith by ROCHE unless SYNTA is successful in such dispute or ROCHE ceases to dispute such payments.

7.7.3. Method of Payment. Royalties on Net Sales and all other amounts payable by ROCHE hereunder shall be paid by or on behalf of ROCHE in U.S. Dollars. All payments due to SYNTA hereunder shall be made directly from an account located in either (at ROCHE’s option) the United States or Switzerland to account(s) designated by SYNTA.

7.7.4. Currency Conversion. Whenever calculating royalties requires conversion from any currency, ROCHE shall make such conversion as follows:

(a) When calculating the Net Sales for countries other than the United States, ROCHE shall convert the amount of such sales in currencies other than Swiss Francs into Swiss Francs using ROCHE’s then current standard practices actually used on a consistent basis in preparing its audited financial statements.

(b) Upon converting the amount of Adjusted Gross Sales into Swiss Francs, ROCHE shall convert into US Dollars (or other currency), using the quarterly average rate (currently Reuters) at the last working day for the applicable period.

7.7.5. Reporting. With each payment ROCHE shall provide SYNTA in writing for the relevant Calendar Quarter on a Licensed Product-by-Licensed Product basis the following information with respect to each of the following territories: (1) the United States, (2) the Major Markets (other than the United States) and Canada, and (3) all territories other than those set forth in the foregoing clause (1) and (2):

(a) Net Sales and Adjusted Gross Sales;

(b) Adjustments made pursuant to Section 7.6; and

(c) Total royalty payable to SYNTA.

The report for the fourth Calendar Quarter shall include a list of all countries in which a Licensed Product is sold in the Territory for the applicable calendar year.

7.7.6. United States Dollars. All dollar ($) amounts specified in this Agreement are United States dollar amounts.

7.7.7. Nonrefundable. All payments made by ROCHE to SYNTA under this Agreement shall be non-refundable and non-creditable, except as expressly set forth in Sections 2.5.2(f), 2.5.4 and 7.9.2.

7.8. Taxes. Any tax required to be withheld by ROCHE under the Laws of any country for the account of SYNTA shall be promptly paid by ROCHE for and on behalf of

SYNTA to the appropriate government authority, and ROCHE shall furnish SYNTA with proof of payment of such tax. Any such tax actually paid on SYNTA’s behalf shall be deducted from royalty payments due to SYNTA hereunder. ROCHE shall assist SYNTA in minimizing the withholding taxes applicable to any payment made by ROCHE and in claiming tax refunds at SYNTA’s request.

7.9. Auditing.

7.9.1. Audit Rights.

(a) ROCHE shall keep, and shall require its Affiliates and Sublicensees to keep, for [] ([]) years, full, true and accurate books of account containing all particulars that may be necessary for the purpose of calculating all royalties and all other amounts payable under this Agreement. Such books of accounts shall be kept at ROCHE’s or the relevant Affiliate’s or Sublicensee’s principal place of business. At the expense of SYNTA, SYNTA has the right to engage an independent, certified public accountant reasonably acceptable to both Parties to perform, on behalf of SYNTA, an audit of such books and records of ROCHE and its Affiliates and Sublicensees, that are deemed necessary by such accountant to report on Net Sales of Licensed Products for the period or periods requested by SYNTA and the correctness of any report or payments made under this Agreement. Such accountant shall not have the authority to interpret this Agreement.

(b) Upon timely request and at least [] ([]) days prior written notice from SYNTA, such audit shall be conducted in the countries specifically requested by SYNTA, during regular business hours in such a manner as to not unnecessarily interfere with ROCHE’s normal business activities, and shall be limited to results in the [] ([]) calendar years prior to audit notification.

(c) Such audit shall not be performed more frequently than once per calendar year nor more frequently than once with respect to records covering any specific period of time.

(d) All information, data and documents herein referred to shall be used only for the purpose of verifying royalty statements, shall be treated as ROCHE Confidential Information subject to the obligations of this Agreement and need neither be retained more than the longer of one (1) year after completion of an audit hereof, if an audit has been requested; nor more than [] ([]) years from the end of the calendar year to which each shall pertain; nor more than [] ([])[***] after the date of termination of this Agreement.

(e) The final audit report shall be shared by ROCHE and SYNTA.

7.9.2. Over- or Underpayment. If the audit reveals an underpayment, ROCHE shall reimburse SYNTA for the amount of the underpayment within [] ([]) days with interest as set forth in Section 7.7.2. If the audit reveals an overpayment, ROCHE shall have the right to credit the amount of such overpayment against the next royalty payment payable to

37 SYNTA hereunder. ROCHE shall pay for the audit costs if the audit reveals that an underpayment of ROCHE exceeds [] percent ([]%).

7.9.3. Duration of Audit Rights. The failure of SYNTA to request verification of any royalty calculation within the period during which the corresponding records must be maintained under Section 7.9.1 will be deemed acceptance of the royalty payments and reports.

ARTICLE VIII -INTELLECTUAL PROPERTY MATTERS

8.1. Know-How.

8.1.1. Ownership. Each Party shall exclusively own all inventions conceived or reduced to practice solely by employees, agents and consultants of such Party or its Affiliates.

The incorporation of such recommended changes shall not be unreasonably refused; and if such other Party notifies (“Notice”) the Publishing Party in writing, within [] ([]) [] after receipt of the copy of the proposed publication or presentation (or at least [] ([]) [] in the case of oral presentations), that such publication or presentation in its reasonable judgment (a) contains an invention, solely or jointly conceived or reduced to practice by the other Party, for which the other Party reasonably desires to obtain patent protection or (b) could be expected to have a material adverse effect on the commercial value of any Confidential Information disclosed by the other Party to the Publishing Party, the Publishing Party shall prevent such publication or delay such publication for a mutually agreeable period of time. In the case of inventions, a delay shall be for a period reasonably sufficient to permit the timely preparation and filing of a patent application(s) on such invention, and in no event less than [] ([]) [***] from the date of the Notice. In the case of Confidential Information, any of the non-publishing Party’s Confidential Information shall be deleted as requested.

14.8. Assignment. Neither this Agreement nor any right or obligation hereunder may be assigned or otherwise transferred by any Party without the written consent of the other Party; provided, however that any Party may, without such consent, assign this Agreement, in whole or in part: (a) to any of its respective Affiliates, provided that such Party shall remain jointly and severally liable with such Affiliate in respect of all obligations so assigned and such Affiliate has acknowledged and confirmed in writing that, effective as of such assignment or other transfer, such Affiliate shall be bound by this Agreement as if it were a party to it as and to the identical extent applicable to the transferor; or (b) to any successor in interest by way of merger or acquisition or by sale of all or substantially all of its assets to which this Agreement pertains (whether by merger, reorganization, acquisition, sale or otherwise), provided, that such successor agrees in writing to be bound by the terms of this Agreement as if it were the assigning party.

The Party affected by such force majeure will provide the other Party with full particulars thereof as soon as it becomes aware of the same (including its good faith estimate of the likely extent and duration of the interference with its activities), and will use Commercially Reasonable Efforts to overcome the difficulties created thereby and to resume performance of its obligations as soon as practicable. If the performance of any such obligation under this Agreement is delayed owing to such a force majeure for any continuous period of more than one hundred eighty (180) days, the Parties will consult with respect to an equitable solution, including the possibility of the mutual termination of this Agreement.

Notwithstanding the foregoing provisions of this Section 14.11 or of Article IX, (a) a Party may make any disclosure or public announcement if the contents of such disclosure or public announcement have previously been made public other than through a breach of this Agreement by the issuing Party; (b) if a Party reasonably determines that a public disclosure shall be required by Law, including in a public filing with the U.S. Securities and Exchange Commission, such Party may disclose the existence and terms of this Agreement

and any material developments that occur under this Agreement where so required, provided that such Party shall, to the extent practicable and permitted by applicable Law, notify the other Party and allow the other Party to comment on the proposed disclosure, which comments shall be considered by the disclosing Party in good faith; (c) a Party may disclose the existence and terms of this Agreement under obligations of confidentiality to bona fide potential or actual advisors, consultants, investors, lenders, investment bankers or other potential financial partners in connection with such Party’s proposed financing or business combination activities; and (d) a Party may disclose the terms and existence of this Agreement to bona fide potential or actual Sublicensees, as reasonably necessary in connection with a permitted sublicense under the licenses granted in this Agreement.

Neither Party shall have any responsibility for the hiring, termination or compensation of the other Party’s employees or for any employee compensation or benefits of the other Party’s employees. No employee or representative of a Party shall have any authority to bind or obligate the other Party for any sum or in any manner whatsoever, or to create or impose any contractual or other liability on the other Party without such other Party’s approval.

Nothing in this Agreement shall be construed to establish a relationship of partners or joint venturers between the Parties.

14.14. Performance by Affiliates. Either Party may use one or more of its Affiliates to perform its obligations and duties hereunder and Affiliates of a Party are expressly granted certain rights herein; provided, that each such Affiliate shall be bound by the corresponding obligations of such Party and the relevant Party shall remain liable hereunder for the prompt payment and performance of all their respective obligations hereunder.

2. Co-promotion Guidelines.

Notwithstanding the foregoing, SYNTA shall have final decision-making authority as to whether it will accept the geographic location and size of its sales territories within the U.S. If SYNTA does not accept a particular geographic location or size of its sales territories within the U.S., then ROCHE shall in good faith discuss with SYNTA a reasonably acceptable alternative such that SYNTA has the ability to provide the Detail Percentage of the annual budgeted Detailing effort for such Co-promoted Product in the United States for the applicable Indication.

SYNTA’s Sales Representatives shall use the promotional materials solely for the purpose of performing their obligations under this Agreement. SYNTA shall require that its Sales Representatives perform Co-promotion activities in compliance with all applicable Laws and the Co-promotion Guidelines.

5. Co-promotion Costs. If SYNTA exercises its right to participate in the Co-promotion of one or more Licensed Products in the United States pursuant to Section 5.3 of this Agreement, then ROCHE shall reimburse SYNTA for all Sales Representative costs incurred by or on behalf of SYNTA or its Affiliates in connection with the Co-promotion of the Co-promoted Product in the United States for the applicable Indication.
