4.3.

Sales Milestone Payments. Licensee will pay to ImmunoGen the following one-time payments (each, a “Sales Milestone Payment”) when aggregate Annual Net Sales of a Product in the Territory in a Calendar Year first reach the respective threshold (a “Sales Threshold”) indicated below (each, a “Sales Milestone”):


SALES MILESTONE		SALES MILESTONE PAYMENT
Total Annual Net Sales at least equal [***]		[***]
Total Annual Net Sales at least equal [***]		[***]

Any Sales Milestone Payment with respect to any Calendar Year will be payable within 30 days of the end of the Calendar Quarter in which such Milestone was achieved. Each Sales Milestone Payment is payable a maximum of one time only, regardless of the number of times a Product achieves a particular Sales Threshold or the number of Products that achieve a particular Sales Threshold. All Sales Milestone Payments will be nonrefundable and noncreditable. For clarity, in no event shall more than [***] be owed by Licensee under this Section 4.3, regardless of the number of times any Sales Milestone may be achieved by all Products.

4.4.

Royalty Payments. With respect to each Product and subject to the provisions of Sections 4.5 (Royalty Adjustments) and this Section 4.4 (Royalty Payments), Licensee will pay ImmunoGen royalties in the amount of the applicable rates (“Marginal Royalty Rates”) set forth below of Annual Net Sales of such Product during the Royalty Term (collectively, “Royalties”):


ANNUAL NET SALES		MARGINAL ROYALTY RATE
Annual Net Sales of such Product during a given Calendar Year up to and including [***]		[***]%
Annual Net Sales of such Product during a given Calendar Year above [*], up to and including [*]		[***]%
Annual Net Sales of such Product during a given Calendar Year above [***]		[***]%

Each Marginal Royalty Rate set forth above will apply only to that portion of the Annual Net Sales of a given Product in the Territory during a given Calendar Year that falls within the indicated range.

4.5.

Royalty Adjustments.

4.5.1.

Third Party Royalty Offset. Subject to Section 4.5.3 (Xxxxxxx Xxxxx) hereof, if Licensee or any of its Affiliates enters into a license agreement with a Third Party after the Effective Date pursuant to which it obtains a license under Patent Rights owned or Controlled by such Third Party that would, but for such license, be infringed by the making, using, or selling of the Product in any country in the Territory and in consideration of such license actually pays royalties to such Third Party (“Third Party Royalties”), then Licensee may reduce the royalties otherwise due to ImmunoGen pursuant to Section 4.4 (Royalty Payments) hereof with respect to Net Sales in such country of such Products in such Calendar Quarter by an amount equal to [***] of the amount of such Third Party Royalties. For purposes of clarity, the term “Third Party Royalties” includes only running royalties paid on sales, and does not include any lump-sum license fees, milestone payments, or sublicense income sharing payments or any amount paid for any Intellectual Property Rights other than Patent Rights that would, but for such license, be infringed by the making, using, or selling of the Product.

4.5.2.

Expiration of Valid Claims. Subject to Section 4.5.3 (Xxxxxxx Xxxxx) hereof, on a Product-by-Product basis and as applicable, in the United States or the PRC, if there is no Valid Claim of a Licensed Patent Right that Covers the composition of matter, method of use, or method of Manufacturing of such Product in the United States or the PRC, then, commencing the first Calendar Quarter after the date on which this Section 4.5.2 (Expiration of Valid Claims) applies and for all Calendar Quarters thereafter during which this Section 4.5.2 (Expiration of Valid Claims) applies, the applicable royalty rate that would otherwise be owed on such Net Sales of such Product in the United States or the PRC under Section 4.4 (Royalty Payments) will be reduced by [***] (for example, an [***] royalty rate would be reduced to a [***] royalty rate); provided that if the composition of matter, method of use, or method of Manufacturing of such Product subsequently becomes Covered by a Valid Claim of a Licensed Patent Right in the United States or the PRC prior to the [***] anniversary of the date of the First Commercial Sale of such Product in the United States or the PRC, then the applicable royalty rate that would otherwise be owed on such Net Sales of such Product in the United States or the PRC will no longer be subject to the aforementioned reduction beginning at the commencement of the first Calendar Quarter after the date on which the relevant patent issues.

4.5.3.

Royalty Floor. Notwithstanding anything in this Agreement to the contrary, the reductions to royalties provided in Sections 4.5.1 (Third

Party Royalty Offset) and Section 4.5.2 (Expiration of Valid Claims), will not, individually or in the aggregate, reduce the royalties payable with respect to Net Sales of any Product sold by Licensee, its Affiliates and its Sublicensees in any country during the Royalty Term by more than [***] of the royalties that otherwise would have been owed to ImmunoGen pursuant to Section 4.4 (Royalty Payments), without giving effect to any royalty reduction provided in Section 4.5.1 (Third Party Royalty Offset) and Section 4.5.2 (Expiration of Valid Claims).

4.6.

Net Sales Reports. Commencing with the Calendar Quarter during which the First Commercial Sale of a Product is made anywhere in the Territory, Licensee will provide ImmunoGen with Net Sales reports as follows:

4.6.1.

Within 10 days after the end of a Calendar Quarter (to the extent such information is available to Licensee), a written preliminary report setting forth the Net Sales for such Calendar Quarter, which report will include the actual Net Sales for the first two months of the applicable Calendar Quarter (subject to any adjustments to be included in the final report under the following Section 4.6.2 (Net Sales Reports)) and a nonbinding, good faith estimate with respect to the Net Sales for the third month of such Calendar Quarter.

4.6.2.

Within 45 days after the end of each Calendar Quarter, Licensee will deliver to ImmunoGen a report setting forth for such Calendar Quarter the following information, on a Product-by-Product and country-by-country basis: (i) the gross sales (if available) and the Net Sales of each Product (specifying in reasonable detail the deductions to gross sales used to calculate Net Sales), (ii) the basis for any adjustments to the royalty payable for the sale of each Product pursuant to Section 4.5 (Royalty Adjustments), (iii) the applicable exchange rate to convert each country’s currency to U.S. Dollars under Section 4.11 (Currency) hereof and (iv) the royalties due hereunder for the sale of each Product. The total royalty due for the sale of Products during such Calendar Quarter will be remitted at the time such report is delivered.

4.7.

[***]. Licensee will reimburse ImmunoGen for [***] of all royalty payments paid by ImmunoGen to [***] (or any successor or assign) pursuant to that certain [***] as a result of Licensee’s or its Affiliates or Sublicensees’ Net Sales of Products pursuant to this Agreement; provided that in no event will such reimbursement obligation exceed an aggregate of [***] of Net Sales of Product in any Calendar Quarter. ImmunoGen will invoice Licensee for such reimbursement on a quarterly basis, and Licensee will pay ImmunoGen such amounts within 30 days of invoice.

4.8.

Cumulative Royalties. The obligation to pay royalties under Section 4.4 (Royalty Payments) will be imposed only once with respect to a single unit of a Product regardless of how many Valid Claims in Patent Rights included within the Licensed Patent Rights would, but for this Agreement, be infringed by the use or sale of such Product in the country in which such Product is used or sold.

4.9.

Sublicense Income. If Licensee grants a sublicense under the rights granted to them under Section 2.1 (License Grants) hereof to a Third Party, then Licensee will pay to ImmunoGen, an amount equal to [***] of all Non-Royalty Sublicense Income that it receives in consideration of such sublicense. Licensee will make such payment to ImmunoGen no later than 30 days after it receives any payment of Non-Royalty Sublicense Income. Licensee will provide ImmunoGen with a written summary of its calculation of the Non-Royalty Sublicense Income at the time of such payment, and at ImmunoGen’s request the Parties will discuss such calculation in good faith.

4.10.

Late Payments. Subject to the other terms of this Agreement, any payments hereunder not paid within the applicable time period set forth herein will bear interest from the due date until paid in full, at a rate per annum equal to the lesser of (a) 1% per month, compounded monthly, or (b) the maximum interest rate permitted by Applicable Law in regard to such payments, calculated in each case from the date such payment was due through to the date on which payment is actually made; provided, however, that with respect to any disputed payments, no interest will be due until such dispute is resolved and the interest that will be payable thereon will be based on the finally-resolved amount of such payment, calculated from the original date on which the disputed payment was due through the date on which payment is actually made. Such payments when made will be accompanied by all interest so accrued. Such interest and the payment and acceptance thereof will not negate or waive the right of ImmunoGen to any other remedy, legal or equitable, to which it may be entitled because of the delinquency of the payment.

4.11.

Currency. Any payments under this Article 4 (Payment Terms) that are recorded in currencies other than the United States Dollar will be converted into United States Dollars at the average of the daily foreign exchange rates published in the Wall Street Journal (or any other qualified source that is acceptable to both Parties) for the Calendar Quarter in which such payments or expenses occurred, or for periods less than a Calendar Quarter, the average of the daily rates published in the Wall Street Journal for such period.

4.12.

Taxes. All payments made by Licensee to ImmunoGen hereunder will be made without set-off or counterclaim and free and clear of any taxes, duties, levies, fees or charges. As both ImmunoGen and Licensee are U.S. entities, the Parties do not anticipate that any tax withholding will be required on any payment due under this Agreement. However, if Licensee assigns this Agreement as permitted by Section 15.1 (Assignment) and as a result of such assignment any tax (other than any tax based on income to ImmunoGen) is required to be withheld and deducted from payments by Licensee pursuant to this Agreement under Applicable Law, then notwithstanding anything to the contrary herein, Licensee will make such deduction and withholding and will pay such additional amounts as may be necessary to

ensure that ImmunoGen receives the amount it would have received had no such withholding applied (including any withholding imposed in respect of such additional amounts), and any amounts so withheld and deducted will be remitted by Licensee on a timely basis to the appropriate governmental authority for the account of ImmunoGen and Licensee will provide ImmunoGen reasonable evidence of the remittance within 30 days thereof.

5.	REPORTING; RECORDS; AUDIT RIGHTS.

5.1.

Adverse Events. Licensee will provide ImmunoGen with (i) notice of Serious Adverse Event and product complaint information relating to any Product and any product containing any Licensed Technology (if applicable) that is compiled and prepared by or on behalf of Licensee or its Affiliates and Sublicensees in the normal course of business in connection with the Development, Commercialization or sale of any such product, within time frames consistent with reporting obligations under Applicable Law and (ii) upon ImmunoGen’s reasonable request, all other Adverse Event information with respect to such products and all other safety data and information relevant to an analysis or investigation of such Adverse Events; provided, however, that the foregoing will not require Licensee to violate any agreements with or confidentiality obligations owed to any Third Party.

5.2.

Relevant Records. Licensee will keep and maintain, and require its Affiliates and Sublicensees to keep and maintain, accurate books of account and records in connection with the sale of Products, in sufficient detail to permit accurate determination of all figures necessary for verification of royalties to be paid hereunder consistent with GAAP, including any records required to calculate any royalty adjustments hereunder (“Relevant Records”). Licensee will maintain, and require its Affiliates and Sublicensees to maintain, such records for a period of at least three years after the end of the Calendar Year in which they were generated.

5.3.

Audit Request. ImmunoGen will have the right during the Term and for three years thereafter to engage, at its own expense, an independent auditor reasonably acceptable to Licensee to examine the Relevant Records from time-to-time, but no more frequently than once every 12 months, as may be necessary to verify compliance with the terms of this Agreement. Such audit will be requested in writing at least seven days in advance, and will be conducted during Licensee’s normal business hours, at the facility(ies) where such records are maintained and otherwise in a manner that minimizes any interference to Licensee’s business operations.

5.4.

Audit Fees and Expenses. Upon 30 days prior written notice from ImmunoGen, Licensee will permit an independent certified public accounting firm of internationally recognized standing selected by ImmunoGen and reasonably acceptable to Licensee to examine, at ImmunoGen’s sole expense, the relevant books and records of Licensee, its Affiliates and Sublicensees during the period covered by such examination, as may be reasonably necessary to verify the accuracy of the reports submitted by Licensee in accordance with Article 4

(Payment Terms) hereof and the payment of royalties hereunder. An examination by ImmunoGen under this Section 5.4 (Audit Fees and Expenses) will occur not more than once in any Calendar Year and will be limited to the pertinent books and records for any Calendar Year ending not more than three years before the date of the request. The accounting firm will be provided access to such books and records at the facilities where such books and records are kept and such examination will be conducted during normal business hours. Licensee may require the accounting firm and its personnel involved in such audit to sign a reasonable and customary non-disclosure agreement as to any confidential information which is to be provided to such accounting firm or to which such accounting firm will have access while conducting the audit under this Section 5.4 (Audit Fees and Expenses) before providing the accounting firm access to Licensee’s facilities or records. Upon completion of the audit, the accounting firm will provide both ImmunoGen and Licensee a written report disclosing whether the reports submitted by Licensee are correct or incorrect, whether the royalties paid are correct or incorrect and, in each case, the specific details concerning any discrepancies. Such accounting firm may not reveal to ImmunoGen any information learned in the course of such audit other than the amount of any such discrepancies. Licensee and ImmunoGen will each have the right to request a further determination by such accounting firm as to matters which such Party disputes within 30 days following receipt of such report. The Party initiating a dispute will provide the other Party and the accounting firm with a reasonably detailed statement of the grounds upon which it disputes any findings in the written report and the accounting firm will undertake to complete such further determination within 30 days after the dispute notice is provided, which determination will be limited to the disputed matters and provided to both Parties. The Parties will use reasonable efforts, through the participation of finance representatives of both Parties, to resolve any dispute arising in relation to the audit by good faith discussion. The results of any such audit, reflecting the accounting firm’s determination of any disputed matters, will be binding on both Parties.

5.5.

Payment of Deficiency. If such accounting firm concludes that additional royalties were due to ImmunoGen, Licensee will pay the additional royalties (plus interest thereon at the rate provided in Section 4.9 (Late Payments) hereof) within 30 days of the date Licensee receives such accountant’s written report so concluding. If such underpayment exceeds [***] of the royalties that were to be paid, Licensee also will reimburse ImmunoGen for all reasonable charges of such accountants for conducting the audit. If such accounting firm concludes that Licensee overpaid royalties, ImmunoGen will repay such amount in full within 30 days of the receipt of such accountant’s report.

6.	INTELLECTUAL PROPERTY RIGHTS.

6.1.

Pre-existing IP. Subject only to the rights expressly granted to the other Party under this Agreement, each Party will retain all rights, title and interests in and to any Intellectual Property Rights that are owned by or licensed or sublicensed to such Party prior to or independent of this Agreement.

In such event, Licensee may, by written notice to ImmunoGen, elect to continue the maintenance or prosecution of the patent or patent application at Licensee’s sole expense but in ImmunoGen’s name, and such patent or patent application will continue to be within the Licensed Patent Rights for all purposes of this Agreement.

6.2.3.

Costs. [***].

6.2.4.

Liability. To the extent that ImmunoGen is obtaining, prosecuting or maintaining a Licensed Patent Right, neither ImmunoGen, nor any of its Affiliates, employees, agents or representatives, will be liable to Licensee in respect of any act, omission, default or neglect on the part of any such Affiliate, employee, agent or representative in connection with such activities taken in good faith.

7.	INFRINGEMENT; MISAPPROPRIATION.

7.1.

Notification. Each Party will promptly notify the other Party in writing of any actual or threatened infringement, misappropriation, other violation or challenge to the validity, scope or enforceability by a Third Party of any Licensed Technology in the Field and in the Territory (but with respect to Licensed Patent Rights, solely to the extent such rights cover the Compound or Product) of which it becomes aware (“Third Party Infringement”).

7.2.

Infringement Action.

7.2.1.

Right of Enforcement.

(a)

Subject to the exceptions described in this Section 7.2 (Infringement Action), Licensee will have the first right (but not

the obligation), at its own expense, to control enforcement of the Licensed Patent Rights against any Third Party Infringement within the scope of its exclusive license. ImmunoGen shall if requested by Licensee, join Licensee as a party for standing purposes (at Licensee’s expense), provided that if ImmunoGen is represented by independent counsel in such action (as determined by ImmunoGen in its sole discretion), each Party will bear the expense of its own counsel. Prior to commencing any such action, Licensee will consult with ImmunoGen and will give due consideration to ImmunoGen’s recommendations regarding the proposed action. Licensee will give ImmunoGen timely notice of any proposed settlement of any such action instituted by Licensee and will not, without the prior written consent of ImmunoGen, enter into any settlement that would (i) adversely affect the validity, enforceability or scope of any of the Licensed Patent Rights, (ii) give rise to liability of ImmunoGen or its Affiliates, or (iii) otherwise impair ImmunoGen’s rights in any Licensed Technology or this Agreement.

(b)

If Licensee does not, with respect to its first right of enforcement under Section 7.2.1(a) (Right of Enforcement), obtain agreement from the alleged infringer to desist or fails or refuses to initiate an infringement action by the earlier of (i) 60 days following Licensee’s receipt of notice of the alleged infringement, or (ii) 30 days before the expiration date for filing such actions, then ImmunoGen will have the right, but not the obligation, at its sole discretion, to control such enforcement of the Licensed Patent Rights and may at its expense join Licensee as a party for standing purposes, provided that if Licensee is represented by independent counsel in such action, each Party will bear the expense of its own counsel. Prior to commencing any such action, ImmunoGen will consult with Licensee and will give due consideration to Licensee’s recommendations regarding the proposed action. ImmunoGen will give Licensee timely notice of any proposed settlement of any such action instituted by ImmunoGen and will not, without the prior written consent of Licensee, enter into any settlement that would: (i) adversely affect the validity, enforceability or scope of any claim within the Licensed Patent Rights which covers the Compound, (ii) give rise to liability of Licensee or its Affiliates, (iii) admit non-infringement of any claim within the Licensed Patent Rights which covers the Compound, or (iv) otherwise impair Licensee’s rights in any Licensed Technology or this Agreement.

7.2.2.

Recoveries. Any recoveries resulting from an action relating to a claim of Third Party Infringement within the scope of Licensee’s exclusive license will first be applied to reimburse each Party’s costs and expenses incurred in connection therewith. Any remaining recoveries will be retained by (or if received by ImmunoGen, paid to) Licensee; provided, however, such remaining recoveries will be apportioned [***] to ImmunoGen and [***] to Licensee. If Licensee fails to institute an action or proceeding and ImmunoGen exercises its right to prosecute such infringement pursuant to Section 7.2.1(b) (Right of Enforcement), any remaining recoveries will be apportioned [***] by ImmunoGen and [***] to Licensee, resulting from an action brought by ImmunoGen relating to any other claim of Third Party Infringement, except that ImmunoGen would retain [***] of any recoveries solely attributable to a claim of Third Party Infringement outside the scope of Licensee’s exclusive license, including with respect to any patent or application within the Licensed Patent Right that does not cover the Compound.

In connection with any Claim for which a Party (the “Indemnified Party”) seeks indemnification from the other Party (the “Indemnifying Party”) pursuant to this Agreement, the Indemnified Party will: (a) give the Indemnifying Party prompt written notice of the Claim; provided, however, that failure to provide such notice will not relieve the Indemnifying Party from its liability or obligation hereunder, except to the extent of any material prejudice as a direct result of such failure; (b) cooperate with the Indemnifying Party, at the Indemnifying Party’s expense, in connection with the defense and settlement of the Claim; and (c) permit the Indemnifying Party to control the defense and settlement of the Claim; provided, however, that the Indemnifying Party may not settle the Claim without the Indemnified Party’s prior written consent, which will not be unreasonably withheld or delayed, in the event that such settlement materially adversely impacts the Indemnified Party’s rights or obligations.

12.

TERM; TERMINATION.

12.1.

Term. The term of this Agreement (“Term”) will commence as of the Effective Date and, unless earlier terminated as expressly provided herein, will extend on a Product-by-Product and country-by-country basis, until such time as the Royalty Term with respect to the sale of such Product in such country expires. Provided this Agreement has not been terminated prior thereto by ImmunoGen under Section 12.2 (Termination for Cause) or 12.3 (Termination for a Bankruptcy Event) hereof or by Licensee under Section 12.3 (Termination for a Bankruptcy Event) or 12.4 (Termination for Convenience) hereof, following the expiration of the Royalty Term applicable to a Product throughout the Territory in accordance with Section 1.69 (Royalty Term) hereof, Licensee will have a fully paid-up, irrevocable, freely transferable and sublicensable, non-exclusive license under the relevant Licensed Technology, to make, have made, use, sell, offer for sale and import such Products in such country.

12.2.

Termination for Cause. Each Party will have the right, without prejudice to any other remedies available to it at law or in equity, to terminate this Agreement in the event the other Party materially breaches any of its obligations hereunder and fails to cure such breach within 90 days of receiving notice thereof; provided, however, if such breach is capable of being cured, but cannot be cured within such 90 day period, and the breaching Party initiates actions to cure such breach within such period and thereafter diligently pursues such actions, the breaching Party will have such additional period as is reasonable to cure such breach, but in no event will such additional period exceed 90 days. Any termination by a Party under this Section 12.2 (Termination for Cause) will be without prejudice to any damages or other legal or equitable remedies to which it may be entitled from the other Party. The foregoing cure periods shall be tolled during the pendency of any Dispute as to whether a material breach has occurred.

12.3.

Termination for a Bankruptcy Event. Each Party will have the right to terminate this Agreement in the event of a Bankruptcy Event with respect to the other Party. “Bankruptcy Event” means the occurrence of any of the following: (a) the institution of any bankruptcy, receivership, insolvency, reorganization or other similar proceedings by or against a Party under any bankruptcy, insolvency, or other similar law now or hereinafter in effect, including any section or chapter of the United States Bankruptcy Code, as amended or under any similar laws or statutes of the United States or any state thereof (the “Bankruptcy Code”), where in the case of involuntary proceedings such proceedings have not been dismissed or discharged within 90 days after they are instituted, (b) the insolvency or making of an assignment for the benefit of creditors or the admittance by a Party of any involuntary debts as they mature, (c) the institution of any reorganization, arrangement or other readjustment of debt plan of a Party not involving the Bankruptcy Code, (d) appointment of a receiver for all or substantially all of a Party’s assets, or (e) any corporate action taken by the board of directors of a Party in furtherance of any of the foregoing actions. For clarity, the Licensed Technology shall be regarded as intellectual property under Section 365(n) of the Bankruptcy Code.

12.4.

Termination for Convenience. Licensee may terminate this Agreement for convenience upon [***] prior written notice to ImmunoGen.

12.5.

Effects of Termination.

12.5.1.

Termination by Licensee for Cause or Bankruptcy Event. In the event that Licensee terminates this Agreement pursuant to Section 12.2 (Termination for Cause) or Section 12.3 (Termination for a Bankruptcy Event), the following will apply:

(a)

Rights and Obligations. Except as otherwise provided herein, all rights and obligations of each Party hereunder will cease, including, subject to Section 12.5.1(b) (Licensee Inventory), the licenses granted to Licensee pursuant to Section 2.1 (License Grant), provided that ImmunoGen will remain entitled to receive payments that accrued before the effective date of such termination. Notwithstanding the foregoing, if this Agreement is terminated by ImmunoGen pursuant to Section 12.2 (Termination for Cause) or Section 12.3 (Termination for a Bankruptcy Event), at the request of any Sublicensee, ImmunoGen will grant such Sublicensee a direct license under the Licensed Patent Rights, Licensed Know-How and Licensed Materials on substantially the same terms as are set forth in the sublicense agreement between Licensee and such Sublicensee, so that the Sublicensee is put in the same position as it was prior

to this Agreement being terminated; provided, however, that (i) ImmunoGen would not have any increased obligations as a result of such direct license to the Sublicensee; (ii) as consideration for such direct license, Sublicensee would be required to pay ImmunoGen the same amount as ImmunoGen would have received from Licensee had this Agreement survived as a result of (x) the applicable sublicense and (y) the exploitation of the Compound and Products; and (iii) any such direct license may be conditioned upon the Sublicensee being in good standing under the terms of the sublicense agreement.

(b)

Licensee Inventory. Licensee will have the right to sell its remaining inventory of Product as of the termination date so long as Licensee has fully paid, and continues to pay when due, all Royalties and Milestone Payments owed to ImmunoGen, and Licensee is otherwise not in material breach of this Agreement. Except with respect to the offering for sale, sale and import of the remaining inventory of Product described above, Licensee will immediately cease, and will cause its Affiliates and Sublicensees to cease, all Development, manufacture, use and Commercialization of Compounds and Products in the Territory.

12.5.2.

Termination by ImmunoGen for Cause, Bankruptcy Event; Termination by Licensee for Convenience. In the event that ImmunoGen terminates this Agreement pursuant to Section 12.2 (Termination for Cause), or Section 12.3 (Termination for a Bankruptcy Event), or Licensee terminates this Agreement pursuant to Section 12.4 (Termination for Convenience), the following will apply:

(a)

Rights and Obligations. Except as otherwise provided herein, all rights and obligations of each Party hereunder will cease, and, except as expressly provided in this Agreement, Licensee will cease all Development, Manufacture, and Commercialization of the Compound and Products.

(b)

Transition. Within 90 days of termination of this Agreement, at ImmunoGen’s sole option, ImmunoGen will prepare and the Parties will negotiate a transition plan that will include, at a minimum, a plan for accomplishing the activities described in this Section 12.5.2(b) (Transition).

(i)

Continued Development. At ImmunoGen’s request and expense, Licensee will continue on-going Development for a mutually agreed-upon period following terminating of this Agreement, which period will be at least three months, but not more than six months, unless otherwise agreed to by the Parties. For avoidance of doubt, if

ImmunoGen chooses not to continue a clinical trial initiated by Licensee, Licensee will be solely responsible for the cost of winding down such trial, including compliance with any ethical or other requirements imposed by an applicable Regulatory Authority.

(ii)

Technology Transfer. At ImmunoGen’s request and expense, Licensee will make available to ImmunoGen all currently available records and data which exist and are Controlled by Licensee as of the effective date of termination and are necessary or useful for ImmunoGen to continue using, Developing, Commercializing and Manufacturing the Product.

(iii)

Regulatory Matters. At ImmunoGen’s request and expense, Licensee will transfer and assign to ImmunoGen (or its designee) all Regulatory Approvals, pricing approvals, and Regulatory Filings held by Licensee with respect to the Product, provided that if such transfer and assignment is not permitted by the applicable Regulatory Authority, Licensee will permit ImmunoGen to cross-reference and rely upon such Regulatory Approvals, pricing approvals and Regulatory Filings. Licensee will make available to ImmunoGen copies of all regulatory documentation and records related to the Product, including information contained in the regulatory and safety databases. The Parties will cooperate to ensure the prompt transition of regulatory responsibilities for the Product from Licensee to ImmunoGen.

(iv)

Trademarks. ImmunoGen will have a fully paid-up, royalty-free, worldwide, transferable, sublicensable, perpetual and irrevocable license to use the trademarks associated exclusively with a Product solely for the purpose of using, Developing, Commercializing and Manufacturing the Product. ImmunoGen will have a transitional license to use Licensee’s trademarks not associated exclusively with a Product and promotional materials solely for the purpose of using, Developing, Commercializing and Manufacturing the Product.

(v)

Inventory and Supply. At ImmunoGen’s request and expense, Licensee will transfer to ImmunoGen (or its designee) all Product, components and in-process inventory produced or held by Licensee with respect to the Manufacture of Products. At ImmunoGen’s request

and expense, Licensee will continue to Manufacture or have Manufactured the Product for a period of not less than 18 months. ImmunoGen will pay to Licensee the actual cost plus 15% of Manufacturing associated with inventory and Product received by ImmunoGen pursuant to this Section 12.5.2(b)(v) (Inventory and Supply).

(vi)

Third Party Agreements. At ImmunoGen’s request and expense, to the extent Licensee is reasonably able to do so, Licensee will assign to ImmunoGen (or its designee) any agreements with Third Parties with respect to the Development, Commercialization and Manufacture of the Product (including any sublicense agreements with a Sublicensee). With respect to Third Party agreements that Licensee is not able to assign to ImmunoGen, Licensee will use reasonable efforts (at the expense of ImmunoGen) to give ImmunoGen the benefit of such contracts for a reasonable transitional period.

(c)

Licensee Inventory. In the event that Licensee terminates this Agreement pursuant to Section 12.4 (Termination for Convenience) and ImmunoGen elects not to initiate transition activities pursuant to Section 12.5.2(b) (Transition), Licensee will have the right to sell its remaining inventory of Product so long as Licensee has fully paid, and continues to pay when due, all Royalties and Milestone Payments owed to ImmunoGen, and Licensee is otherwise not in material breach of this Agreement. Except with respect to the offering for sale, sale and import of the remaining inventory of Product described above, Licensee will immediately cease, and will cause its Affiliates and Sublicensees to cease, all Development, Manufacture, use and Commercialization of Compounds and Products in the Territory.

(d)

ImmunoGen Indemnification. ImmunoGen will indemnify, hold harmless and defend Licensee and its Affiliates, and their respective officers, directors, employees, contractors, agents and assigns, from and against any Claims to the extent arising or resulting from the Development, Manufacture or use of Compound and Product by ImmunoGen, its Affiliates, subcontractors or Sublicensees after the effective date of such termination, except to the extent such Claim is caused by (i) a material breach by Licensee of any of its obligations, representations, warranties or covenants set forth in this Agreement, or (ii) Licensee’s, or its Affiliates’ or Sublicensees’, negligence, recklessness or intentional acts. The process for such indemnification will be governed by Section 10.3 (Indemnification Procedure) mutatis mutandis.

12.6.

Survival. Any expiration or termination of this Agreement will not preclude the terminating Party from exercising any other of those remedies to which it may be entitled under this Agreement or Applicable Law, or terminate any right to obtain performance of any obligation provided for in this Agreement that will survive termination. Expiration or termination of this Agreement will not relieve the Parties of any obligation accruing hereunder prior to such expiration or termination. Without limiting the foregoing, the provisions of this Section 12.6 (Survival), Article 1 (Definitions), Article 4 (Payment Terms) (to the extent applicable to Licensee’s Development or Commercialization of Products during the Term or as expressly permitted by this Agreement thereafter), Article 5 (Reporting; Records; Audit Rights), Section 6.1 (Pre-existing IP), Section 6.2.4 (Liability), Section 7.2.2 (Recoveries), Article 8 (Confidentiality), Section 9.7 (No Other Warranties), Article 10 (Indemnification), Article 11 (Limitation of Liability), Section 12.5 (Effects of Termination), Article 13 (Publicity; Publications), Article 14 (Dispute Resolution) and Article 15 (General Provisions) will survive expiration or termination of this Agreement.

13.

PUBLICITY; PUBLICATIONS.

13.1.

Use of Names. Subject to ImmunoGen’s rights pursuant to Section 12.5.2(b)(iv) (Trademarks), neither Party (nor any of its Affiliates or agents) will use the registered or unregistered trademarks, service marks, trade dress, trade names, logos, insignia, domain names, symbols or designs of the other Party or its Affiliates in any press release, publication or other form of promotional disclosure without the prior written consent of the other Party in each instance.

13.2.

Press Releases. Except as may be expressly permitted under Section 8.2.3 (SEC Filings and Other Disclosures), neither Party will make any public announcement regarding the existence or terms of this Agreement without the prior written approval of the other Party, such approval not to be unreasonably withheld. For the sake of clarity, nothing in this Agreement will prevent either Party from making any public disclosure relating to this Agreement if the contents of such public disclosure have previously been made public other than through a breach of this Agreement by the issuing Party or its Affiliates. The Parties agree that each Party may issue future announcements concerning Licensee’s achievement of any significant milestones, including the selection of a clinical candidate, under this Agreement, provided that the content of any such announcement by ImmunoGen has been mutually agreed upon by the Parties or contains only information that has been previously publicly announced by Licensee. The foregoing notwithstanding, ImmunoGen may publicly announce the achievement of any Development Milestone or Sales Milestone entitling ImmunoGen to receive a payment pursuant to Sections 4.2 (Development Milestone Payments) or 4.3 (Sales Milestone Payments), provided that ImmunoGen will submit to Licensee for prior review a draft of the proposed announcement to the extent including information that is not covered in the second sentence of this Section 13.2 (Press Releases) (“Additional Information”), incorporate any reasonable comments made by Licensee on

Additional Information, and cooperate with Licensee on the timing of such announcement where required for Licensee to comply with applicable securities laws, rules and regulations.

Such review and approval will be conducted for the purposes of preserving the value of the Licensed Technology and determining whether any portion of the proposed publication or presentation containing ImmunoGen’s Confidential Information should be modified or deleted. Written copies of such proposed publication or presentation required to be submitted hereunder will be submitted to ImmunoGen no later than 15 days before the relevant submission date for such publication or presentation (the “Review Period”). ImmunoGen will provide its comments with respect to such publications and presentations within seven days of its receipt of such written copy and Licensee will incorporate all appropriate changes proposed by Licensee regarding its Confidential Information and will delete all Confidential Information of ImmunoGen as ImmunoGen may request. Licensee will comply with standard academic practice regarding authorship of scientific publications and recognition of contribution of other parties in any publication governed by this Section 13.3 (Publications), including International Committee of Medical Journal Editors standards regarding authorship and contributions.

14.

DISPUTE RESOLUTION.

14.1.

Arbitration. The Parties recognize that a bona fide dispute as to certain matters may arise from time to time during the Term relating to either Party’s rights or obligations hereunder or otherwise relating to the validity, enforceability or performance of this Agreement, including disputes relating to alleged breach or termination of this Agreement but excluding any disputes relating to Article 8 (Confidentiality) hereof or disputes relating to the determination of the validity, scope, infringement, enforceability, inventorship or ownership of the Parties’ respective Patent Rights (hereinafter, a “Dispute”). In the event of the occurrence of any Dispute, the Parties will follow the following procedures in an attempt to resolve the dispute or disagreement:

14.1.1.

The Party claiming that such a Dispute exists will give notice in writing (a “Notice of Dispute”) to the other Party of the nature of the Dispute.

14.1.2.

The Dispute will be referred to the then Chief Executive Officer of ImmunoGen and the then Chief Executive Officer of Licensee who will meet no later than 60 days following the initial receipt of the Notice of Dispute and use reasonable endeavors to resolve the Dispute.

14.1.3.

If, within 60 days of initial receipt of the Notice of Dispute, the Dispute has not been resolved, or if, for any reason, the meeting described in Section 14.1.2 (Arbitration) hereof has not been held within 60 days of initial receipt of the Notice of Dispute, then the Parties agree that such Dispute will be finally resolved through binding arbitration to be administered by JAMS pursuant to its Comprehensive Arbitration Rules and Procedures and in accordance with the Expedited Procedures in those Rules, as specifically modified by the provisions of this Section 14.1.3 (Arbitration).

(a)

Arbitration Panel. The arbitration will be conducted by a panel of three arbitrators. Within 30 days after the initiation of the arbitration, each Party will nominate one person to act as arbitrator, and the two arbitrators so named will then jointly appoint the third arbitrator within 30 days of their appointment, who will serve as chairman of the panel. All three arbitrators must be independent Third Parties having at least 10 years of dispute resolution experience (which may include judicial experience) and/or legal or business experience in the biotech or pharmaceutical industry. If either Party fails to nominate its arbitrator, or if the arbitrators selected by the Parties cannot agree on a person to be named as chairman within such 30-day period, JAMS will make the necessary appointments for such arbitrator(s) or the chairman. Once appointed by a Party, such Party will have no ex parte communication with its appointed arbitrator.

(b)

Location and Proceedings. The place of arbitration will be in the Borough of Manhattan, City of New York, NY or such other venue as the Parties may mutually agree. The arbitration proceedings and all communications with respect thereto will be in English. Any written evidence originally in another language will be submitted in English translation accompanied by the original or a true copy thereof. The arbitrators have the power to decide all matters in Dispute, including any questions of whether or not such matters are subject to arbitration hereunder. The arbitration will be governed by the Federal Arbitration Act, 9 U.S.C. §§1 et seq., and judgment upon the award rendered by the arbitrators may be entered in any court having competent jurisdiction thereof.

(c)

Limitation on Awards. Except for breaches of Article 6 (Intellectual Property Rights) hereof, the arbitrators will have no authority to award any SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY OR OTHER SIMILAR DAMAGES. Each Party will bear its own costs and expenses (including attorneys’ fees and expert or consulting

fees) incurred in connection with the arbitration. The Parties will equally (50/50) share the arbitrators’ fees and other administrative costs and expenses associated with the arbitration.

(d)

Confidentiality. The existence, content and results of any arbitration proceedings pursuant to this Section 14.1.3 (Arbitration) will be deemed the Confidential Information of both Parties.

14.1.4.

Notwithstanding any provision of this Agreement to the contrary, either Party may immediately initiate litigation in any court of competent jurisdiction seeking any remedy at law or in equity, including the issuance of a preliminary, temporary or permanent injunction, to preserve or enforce its rights under this Agreement.

14.2.

Patent Disputes and Disputes Relating to Article 6 (Intellectual Property Rights).

14.2.1.

Inventorship. Any dispute, controversy or claim between the Parties involving the inventorship of any Licensed Patent Rights that is not resolved by mutual agreement of the Party’s respective chief patent counsels (or persons with similar responsibilities) within 30days after the date the dispute is raised by one or both of the Parties will be submitted to an independent patent counsel mutually selected by each Party’s respective chief patent counsels (or persons with similar responsibilities) for resolution. Such independent patent counsel’s determination of inventorship, absent manifest error, will be final and binding on the Parties; provided, however, that any such determination with respect to a patent application will not preclude either Party from disputing inventorship with respect to any patents issuing from such patent application, which disputes will be resolved in accordance with this Section. The Parties will equally (50/50) share the independent patent counsel fees and expenses related to the independent patent counsel’s determination of inventorship.

14.2.2.

Other Patent Disputes. Any dispute, controversy or claim between the Parties that involves the validity, scope, infringement, enforceability or ownership of the Parties’ respective Patent Rights (a) that are pending or issued in the United States will be subject to actions before the United States Patent and Trademark Office and/or submitted exclusively to the federal court located in the jurisdiction where the defendant resides (provided that if such Party does not reside in the United States, venue will be the jurisdiction where such Party’s principal U.S. Affiliate resides) and (b) that are pending or issued in any other country (or region) will be brought before an appropriate regulatory or administrative body or court in that country (or region), and the Parties hereby consent to jurisdiction and venue in such courts and bodies.

14.2.3.

Disputes Relating to Article 6 (Intellectual Property Rights). Any dispute, controversy or claim between the Parties that relates to the enforcement of Article 6 (Intellectual Property Rights) hereof will be subject to action in any court of competent jurisdiction.

15.

GENERAL PROVISIONS.

15.1.

Assignment. Neither Party may assign this Agreement without the prior written consent of the other Party, which consent will not be unreasonably withheld, conditioned or delayed, except that such consent will not be required in connection with any assignment to an Affiliate of the assigning Party, or to a Third Party in connection with a sale or transfer of the business to which this Agreement relates, or to any successor Person resulting from any merger or consolidation of such Party with or into such Person, provided that the assignee will have agreed in writing to assume all of the assignor’s obligations hereunder, and provided, further, that the other Party will be notified promptly after such assignment has been effected. Any such assignment will not relieve the assigning Party of any liabilities or obligations owed to the other Party hereunder, without limitation, in the case of Licensee, the payment of any amounts described in Article 4 (Payment Terms) hereof. Any purported assignment of this Agreement in violation of this Section 15.1 (Assignment) will be null and void.

15.2.

Severability. If any clause or portion thereof in this Agreement is for any reason held to be invalid, illegal or unenforceable, the same will not affect any other portion of this Agreement, as it is the intent of the Parties that this Agreement will be construed in such fashion as to maintain its existence, validity and enforceability to the greatest extent possible. In any such event, this Agreement will be construed as if such clause or portion thereof had never been contained in this Agreement, and there will be deemed substituted therefor such provision as will most nearly carry out the intent of the Parties as expressed in this Agreement to the fullest extent permitted by Applicable Law.

15.3.

Governing Law. This Agreement, and all claims arising under or in connection therewith, will be governed by and interpreted in accordance with the substantive laws of the State of New York, without regard to conflict of law principles thereof.

The waiver by either of the Parties of any breach of any provision hereof by the other Party will not be construed to be a waiver of any succeeding breach of such provision or a waiver of the provision itself.

15.5.

Amendment. No amendment, modification or supplement of any provision of this Agreement will be valid or effective unless made in writing and signed by a duly authorized officer of the Party to be bound.

15.6.

Relationship of the Parties. The Parties understand and agree that this Agreement is limited to the activities, rights and obligations as expressly set forth herein. Nothing herein contained will be deemed to create an employment, agency, joint venture or partnership relationship between the Parties hereto or any of their agents or employees, or any other legal arrangement that would impose liability upon one Party for the act or failure to act of the other Party. Neither Party will have any express or implied power to enter into any contracts or commitments or to incur any liabilities in the name of, or on behalf of, the other Party, or to bind the other Party in any respect whatsoever.

15.7.

Successors and Assigns. This Agreement will be binding upon and inure to the benefit of the Parties hereto and their respective successors and permitted assigns.
