4.2.2 Third Party Royalty Offset. Subject to the other terms of this Agreement, on a country-by-country basis, the royalties otherwise due and payable by GENENTECH under Section 4.2.1 above (but not the royalties otherwise due and payable by GENENTECH under Section 4.2.3(a) or (b) below) shall be reduced as provided in this Section 4.2.2:

(a) GENENTECH Process Development. Consistent with GENENTECH’S due diligence obligations under this Agreement, GENENTECH agrees to exercise due diligence to attempt to Develop a commercially viable manufacturing process relating to the manufacture and supply of Licensed Products. For purposes of this Agreement, GENENTECH shall determine in good faith the commercial viability of any such manufacturing process that is Developed hereunder, taking into account, without limitation, the following factors relevant thereto: the consistency and reproducibility of the process itself; the consistency, reproducibility, safety and efficacy of the resulting conjugated Licensed Products; any regulatory issues; the availability of capacity; the cost of goods and other components of Fully Burdened Manufacturing Cost as applied to such process and to the overall manufacture and supply of Licensed Products; the overall profitability of the Licensed Products; and the ability to produce at commercial scale quantities.

(b) Partial Offset. If GENENTECH is not able to Develop such a commercially viable manufacturing process after exercising due diligence as required hereunder, GENENTECH may elect to license a manufacturing process from a Third Party, and in that event GENENTECH shall be entitled to offset up to [***] percent ([***]%) of any Third Party Payments it makes in connection with any license providing rights to any such manufacturing

process against the royalties due to IMMUNOGEN pursuant to Section 4.2.1 above, subject to the clause (d) of this Section 4.2.2. GENENTECH shall not be entitled to the offset under this clause (b) if it fails to exercise due diligence as required hereunder.

(c) Full Offset. If GENENTECH determines in good faith that it is necessary, in order to exploit the license granted to it under Section 2.1 of this Agreement in any country, to make royalty payments to any Third Party (“Third Party Payments”) under any license agreement that GENENTECH determines, in good faith, is necessary in connection with the Development, manufacture, use or sale of any MAY Compound, the linker of any MAY Compound to a [***] Antibody, and/or the conjugation of a [***] Antibody to any MAY Compound (including, without limitation, DM1) as part of any Licensed Product, then in any such case the royalties due to IMMUNOGEN pursuant to Section 4.2.1 above for such Licensed Product shall be reduced by [***] of such Third Party Payments, subject to the limitations set forth in clause (d) of this Section 4.2.2. If GENENTECH elects to take any such license agreement as described herein without having first determined that it is necessary (as determined by GENENTECH in good faith) in order to exploit the license granted to it under Section 2.1 of this Agreement in any country, then GENENTECH shall not be entitled to the offset under this clause (c). If IMMUNOGEN in good faith disputes GENENTECH’s determination hereunder, the Parties shall submit the matter promptly to IMMUNOGEN’S Chief Executive Officer and a designated officer of GENENTECH with settlement authority.

(d) Limitations on Offsets. The royalty offset in Section 4.2.2(c) above is separate and cumulative to the royalty offset under Section 4.2.2(b) above, but each is subject to the limitations set forth in this Section 4.2.2(d) as follows. No royalty reductions under this Section 4.2.2, alone or in the aggregate, shall reduce the royalty (if any) for any Licensed Product in any country payable pursuant to Section 4.2.1 above by more than [***] percent ([***]%) of the royalties otherwise owed to IMMUNOGEN thereunder, nor reduce such royalty for such Licensed Product in any such country to less than [***] percent ([***]%) of Net Sales of such Licensed Product in such country.

4.2.3 [***] and [***].

(a) Notwithstanding anything set forth in [***] above, the [***] set forth therein shall apply, on a [***] and [***] basis, to [***] of [***] or its [***], [***] or [***] in [***] would, [***] for the [***] under this Agreement, [***] a [***] the [***] (excluding any

4.2.4 Combination Products. In determining Net Sales of any Combination Products under this Agreement, Net Sales shall first be calculated in accordance with the definition of “Net Sales” above, then multiplied by the percentage value of the Licensed Product contained in the Combination Product, such percentage value being the quotient obtained by dividing the current market price of the Licensed Product by the sum of the separate current market price of the Licensed Product and other ingredients which are therapeutically active contained in the Combination Product. The current market price of each therapeutically active ingredient and of the Licensed Product shall be for a quantity comparable to that contained in the Combination Product and of the same class, purity and potency. When no current market price is available for any therapeutically active ingredient or for the Licensed Product, GENENTECH shall calculate in good faith a hypothetical market price with respect to the Combination Product, allocating the same proportions of costs, overhead and profit as are then allocated to all similar substances then being made and marketed by GENENTECH and having an ascertainable market price; provided, however, that if IMMUNOGEN in good faith disputes GENENTECH’s calculation, the Parties shall submit the matter promptly to IMMUNOGEN’S Chief Executive Officer and a designated officer of GENENTECH with settlement authority.

4.3 One Royalty. Only one royalty, calculated at the highest applicable royalty rate under this Section 4, shall be payable to IMMUNOGEN hereunder for each sale of a Licensed Product.

4.4 Royalty Term. GENENTECH shall pay royalties with respect to each Licensed Product on a country-by-country and Licensed Product-by-Licensed Product basis until the later of (a) ten (10) years from the First Commercial Sale of such Licensed Product in such country and (b) the expiration of the last to expire Valid Claim of the Licensed Patent Rights covering the Licensed Product in such country. Following such royalty term, GENENTECH shall have a fully paid-up, irrevocable, freely transferable and sublicensable license in such country under the relevant Licensed Patent Rights and Licensed Technology, to Develop, have Developed, make, have made, use, have used, sell, have sold, offer for sale, import and have imported such Licensed Product in such country.

4.5 Payment Terms.

(a) Payment of Milestones; Payment of Royalties; Royalty Reports. All [***] Milestone payments shall be made within [***] days after the first achievement of each of the [***] Milestones described above. All [***] Milestones payments shall be paid no later than the [***] of the [***] of the [***] following the [***] in which the applicable [***] Milestone is achieved, including in any circumstance in which [***] Milestones are achieved in the [***]. Subject to the other terms of this Agreement (including Section 4.1 above), GENENTECH shall make any milestone payments owed to IMMUNOGEN hereunder in United States Dollars, using the wire transfer provisions of this Section 4.4. Subject to the other terms of this Agreement (including Sections 4.2, 4.3 and 4.4 above), GENENTECH shall make any royalty payments owed to IMMUNOGEN in United States Dollars, quarterly within [***] days following the end of each calendar quarter for which such royalties are deemed to occur (as provided in the next sentence), using the wire transfer provisions of this Section 4.5. For purposes of determining when a sale of any Licensed Product occurs under this Agreement, the sale shall be deemed to occur on the earlier of (i) the date the Licensed Product is [***] or (ii) the date of the [***] the [***] of the Licensed Product. Each royalty payment shall be accompanied by a report for each country in the Territory in which sales of Licensed Products occurred in the calendar quarter covered by such statement, specifying: the gross sales (if available) and Net Sales in each country’s currency; the applicable royalty rate under this Agreement; the royalties payable in

each country’s currency, including an accounting of deductions taken in the calculation of Net Sales; the applicable exchange rate to convert from each country’s currency to United States Dollars under this Section 4.5; and the royalties payable in United States Dollars.

(b) Foreign Currency Exchange. All royalties shall be payable in full in the United States in United States Dollars, regardless of the countries in which sales are made. For the purpose of computing Net Sales for Licensed Products sold in any currency other than United States Dollars, the quarterly royalty payment will be calculated as follows:

(A/B) x C = United States Dollars royalty payment on foreign current sales, where

A = foreign current “Net Sales” (as defined above) per quarter;

B = foreign exchange conversion rate, expressed in local currency per United States Dollar (using as the applicable foreign exchange rate the average of the rate published in the [***] of the [***], for the [***] of the calendar quarter); and

C = the royalty rate applicable to such Net Sales under this Agreement.

(c) Tax Withholding; Restrictions on Payment. All payments hereunder shall be made free and clear of any taxes, duties, levies, fees or charges, except for withholding taxes (to the extent applicable). GENENTECH shall make any applicable withholding payments due on behalf of IMMUNOGEN and shall promptly provide IMMUNOGEN with written documentation of any such payment sufficient to satisfy the requirements of the United States Internal Revenue Service relating to an application by IMMUNOGEN for a foreign tax credit for such payment. If by law, regulations or fiscal policy of a particular country in the Territory, remittance of royalties in United States Dollars is restricted or forbidden, written notice thereof shall promptly be given to IMMUNOGEN, and payment of the royalty shall be made by the deposit thereof in local currency to the credit of IMMUNOGEN in a recognized banking institution designated by IMMUNOGEN by written notice to GENENTECH. When in any country in the Territory the law or regulations prohibit both the transmittal and the deposit of royalties on sales in such country, royalty payments shall be suspended for as long a such prohibition is in effect and as soon as such prohibition ceases to be in effect, all royalties that GENENTECH would have been under an obligation to transmit or deposit but for the prohibition shall forthwith be deposited or transmitted, to the extent allowable.

(d) Wire Transfers. All payments hereunder shall be made to IMMUNOGEN by bank wire transfer in immediately available funds to the account designated by IMMUNOGEN by written notice to GENENTECH from time to time.

4.6 Overdue Royalties. Subject to the other terms of this Agreement, royalties not paid within the time period set forth in this Section 4 shall bear interest at a rate of [***] percent ([***]%) per month from the due date until paid in full.

4.7 Records Retention; Review.

(a) Royalties. Commencing as of the date of First Commercial Sale of the first Licensed Product, GENENTECH and its Sublicensees shall keep for at least [***] ([***]) years from the end of the calendar year to which they pertain complete and accurate records of sales by GENENTECH or its Sublicensees, as the case may be, of each Licensed Product, in sufficient detail to allow the accuracy of the royalties to be confirmed.

(b) Fully Burdened Manufacturing Costs. Commencing as of the Effective Date, IMMUNOGEN shall keep for at least [***] years following the end of the calendar year to which they pertain complete and accurate records of all of IMMUNOGEN’s Fully Burdened Manufacturing Costs for Preclinical Materials and Clinical Materials supplied to GENENTECH (or its Sublicensee) hereunder, in sufficient detail to allow the accuracy of the Fully Burdened Manufacturing Costs to be confirmed.

(c) Review. Subject to the other terms of this Section 4.7(c), at the request of either Party, upon at least [***] business days’ prior written notice from the requesting Party, and at the expense of the requesting Party (except as otherwise provided herein), the other Party shall permit an independent certified public accountant reasonably selected by the requesting Party and reasonably acceptable to the other Party to inspect (during regular business hours) the relevant records required to be maintained by the other Party under this Section 4.7. At IMMUNOGEN’s request (which shall not be made more frequently than once per year during the Term), the accountant shall be entitled to review the then-preceding [***] years of GENENTECH’s records under this Section 4.7 for purposes of verifying GENENTECH’s royalty calculations. At GENENTECH’s request (which shall not be made more frequently than once per year during the Term), the accountant shall be entitled to review the then-preceding [***] years of IMMUNOGEN’s records under this Section 4.7 for purposes of verifying IMMUNOGEN’s Fully Burdened Manufacturing Cost calculations. In every case the accountant

must have previously entered into a confidentiality agreement with both Parties substantially similar to the provisions of Section 4 and limiting the disclosure and use of such information by such accountant to authorized representatives of the Parties and the purposes germane to this Section 4.7. Results of any such review shall be made available to both Parties and shall be binding on both Parties. Each Party agrees to treat the results of any such accountant’s review of the other Party’s records under this Section 4.7 as Confidential Information of the other Party subject to the terms of Section 5. If any review reveals a deficiency in the calculation of royalties resulting from any underpayment by GENENTECH, GENENTECH shall promptly pay IMMUNOGEN the amount remaining to be paid (plus interest thereon at the rate provided in Section 4.6 above), and if such underpayment is by [***] percent ([***]%) or more, GENENTECH shall pay all costs and expenses of the review. If any review reveals a deficiency in the calculation of Fully Burdened Manufacturing Costs resulting from any overpayment by GENENTECH, IMMUNOGEN shall promptly refund GENENTECH the amount of any such overpayment (plus interest thereon at the rate provided in Section 4.6 above), and if such overpayment is by [***] percent ([***]%) or more, IMMUNOGEN shall pay all costs and expenses of the review.

5. TREATMENT OF CONFIDENTIAL INFORMATION

During the Term, in the course of performance of this Agreement, each Party may disclose to the other Party proprietary technical and business information of the disclosing Party, including techniques, data, inventions, practices, methods, knowledge, know-how, test data and results (including from pre-clinical and/or human clinical testing), analytical and quality control data, cost, sales, manufacturing, patent data and any other information disclosed hereunder. Such information of the disclosing Party hereunder, if so identified in writing by the disclosing Party to the receiving Party either pursuant to this Section 5.1 or otherwise upon disclosure to the receiving Party, shall be considered “Confidential Information” of the disclosing Party. Each Party agrees that it will take the same commercially reasonable steps to protect the confidentiality of other Party’s Confidential Information as it takes to protect its own proprietary and confidential information. For a period of [***] years after the receipt of any such Confidential Information from the disclosing Party hereunder, subject to the terms of this Section 5, the receiving Party shall keep confidential and not disclose (by publication or otherwise) such Confidential Information of the other Party, and shall not use,

publish or otherwise disclose Confidential Information of the other Party for any purpose other than those contemplated by this Agreement (including as reasonably necessary to exercise any rights or perform any obligations under this Agreement). Notwithstanding the foregoing, it is understood and agreed that the receiving Party’s obligations of confidentiality and non-use herein shall not apply to the extent that it can be established by competent written records that any such information:

(a) is, at the time of disclosure by the disclosing Party hereunder, or thereafter becomes, a part of the public domain or publicly known or available, other than through any act or omission of the receiving Party in breach of its obligations under this Section 5; or

(b) was known to the receiving Party at the time of disclosure to it by the disclosing Party; or

(c) is, at the time of disclosure by the disclosing Party hereunder, or thereafter becomes, known to the receiving Party from a source that had a lawful right to disclose such information to others; or

(d) was independently developed by the receiving Party without use or reference to any Confidential Information of the disclosing Party.

5.2 Permitted Disclosures; Publications.

6. PROVISIONS CONCERNING THE FILING, PROSECUTION AND MAINTENANCE OF PATENT RIGHTS

6.1 Ownership of Intellectual Property.

(a) Sole Inventions. IMMUNOGEN shall own all inventions (whether or not patentable) made during the course of and pursuant to activities carried out under this Agreement solely by employees of or agents or others obligated to assign inventions to IMMUNOGEN. GENENTECH shall own all inventions (whether or not patentable) made during the course of and pursuant to activities carried out under this Agreement solely by employees of or agents or others obligated to assign inventions to GENENTECH. The Party solely owning any inventions hereunder shall be the sole owner of any inventorship certificate(s), patent application(s) and patent(s) thereon. All determinations of inventive contribution shall be as determined by United States laws of inventorship. Subject to the terms of Section 6.2 below relating to IMMUNOGEN sole inventions, the Party solely owning an invention hereunder will be solely responsible, at its own cost and expense and in its sole discretion, for the filing, prosecution and maintenance of any inventorship certificate(s), patent application(s) and patent(s) thereon.

(b) Joint Inventions. Inventions made during the course of and pursuant to activities carried out under this Agreement jointly by employees of or agents of or others obligated to assign inventions to IMMUNOGEN and GENENTECH shall be jointly owned by IMMUNOGEN and GENENTECH. All determinations of inventive contribution shall be as determined by United States laws of inventorship. The Parties shall also jointly own any inventorship certificate(s), patent application(s) and patent(s) on any joint inventions hereunder. The terms of Section 6.2 below relating to joint inventions shall apply to any inventorship certificate(s), patent application(s) and patent(s) thereon.

(c) Disclosure. As regards any IMMUNOGEN sole or joint invention hereunder or any GENENTECH joint inventions hereunder, each Party shall provide to the other Party any invention disclosure made during the course of performance of this Agreement and relating to activities carried out hereunder within [***] days after such Party receives such disclosure from its employees, agents or others obligated to assign inventions to such Party.

(d) Other Agreements. An invention made during the course of and pursuant to other agreements between the Parties, including agreements related to process development or

manufacturing, will be considered to be made under that separate agreement and not under this Agreement.

6.2 Patent Filing, Prosecution and Maintenance.

(a) Sole IMMUNOGEN Inventions. Subject to the other terms of this Section 6.2(a) and Section 6.2(b), IMMUNOGEN shall have the right to prepare, file, prosecute, obtain and maintain, at its sole cost and expense, all Licensed Patent Rights. IMMUNOGEN agrees that with respect to such Licensed Patent Rights licensed exclusively to GENENTECH hereunder, (i) any such preparation, filing, prosecution and maintenance shall be conducted with commercially reasonable diligence by IMMUNOGEN, using patent counsel selected by IMMUNOGEN and reasonably acceptable to GENENTECH. In any case IMMUNOGEN (i) will provide GENENTECH with a copy of any proposed patent application covering any such Licensed Patent Rights for review and comment reasonably in advance of filing (which shall under no circumstances be in excess of [***] days), and (ii) will keep GENENTECH reasonably informed of the status of such filing, prosecution and maintenance, including, without limitation, (A) by providing GENENTECH with copies of all communications received from or filed in patent office(s) with respect to such filing, and (B) by providing GENENTECH, a reasonable time prior to taking or failing to take any action that would affect the scope or validity of any such of any such filing (including the substantially narrowing, cancellation or abandonment of any claim(s) without retaining the right to pursue such subject matter in a separate application, or the failure to file or perfect the filing of any claim(s) in any country), with prior written notice of such proposed action or inaction so that GENENTECH has a reasonable opportunity to review and comment. Any application for extension of Licensed Patent Rights in the Territory due to delays in regulatory review with respect to any Licensed Product shall be filed only upon mutual written agreement of the Parties. If IMMUNOGEN fails to undertake the filing(s) of any patent application with respect to any invention under such Licensed Patent Rights within [***] days after receipt of written notice from GENENTECH that GENENTECH believes filing of such an application by IMMUNOGEN is appropriate, GENENTECH may undertake such filing(s) at its own expense, in which case IMMUNOGEN will assign all of its rights to such invention to GENENTECH and any subsequently issued patent thereon will be owned solely by GENENTECH.

(b) Joint Inventions. As regards any joint invention by the Parties hereunder, the Party from whom the majority of the data underlying any such joint invention arose (the “controlling Party”) will have the first right, but not the obligation, to undertake filing(s), prosecution and maintenance of inventorship certificate(s), patent application(s) and patent(s) thereon. In connection with any such filing(s), the filing Party will use patent counsel mutually acceptable to each Party (in its reasonable determination) and the Parties will, prior to filing of the patent application, agree on mutually acceptable sharing of the costs and expenses of such filing(s), prosecution and maintenance. In any case the filing Party (i) will provide the non-controlling Party with a copy of any such proposed patent application for review and comment reasonably in advance of filing, and (ii) will keep the non-controlling Party reasonably informed of the status of such filing, prosecution and maintenance, including, without limitation, (A) by providing the non-controlling Party with copies of all communications received from or filed in patent office(s) with respect to such filing, and (B) by providing the non-controlling Party, a reasonable time prior to taking or failing to take any action that would affect the scope or validity of any such filing (including the substantially narrowing, cancellation or abandonment of any claim(s) without retaining the right to pursue such subject matter in a separate application, or the failure to file or perfect the filing of any claim(s) in any country), with prior written notice of such proposed action or inaction so that the non-controlling Party has a reasonable opportunity to review and comment. If the Party from whom the majority of the data underlying any such joint invention fails to undertake the filing(s) of any such patent application with respect to any such invention within [***] days after receipt of written notice from the other Party that the other Party believes filing(s) of such an application by such Party is appropriate, such other Party may undertake such filing(s) at its own expense, in which case the non-filing Party will assign all of its rights to such joint invention to the filing Party and any subsequently issued patent thereon will be owned solely by the filing Party. Either Party may assign its rights hereunder to any jointly owned invention, inventorship certificate, patent application or patent to the other Party, who will then have the right, in its discretion, to assume the filing, prosecution and/or maintenance thereof as the sole owner thereof and at its sole cost and expense.

6.3 Notice of Infringement. If, during the Term of this Agreement, either Party learns of any actual, alleged or threatened infringement by a Third Party of any Licensed Patent Rights under this Agreement, such Party shall promptly notify the other Party and shall provide such other Party with available evidence of such infringement.

6.4 Infringement of Patent Rights.

(a) Sole IMMUNOGEN Inventions. IMMUNOGEN shall have the first right (but not the obligation), at its own expense, to bring suit (or take other appropriate legal action) against any actual, alleged or threatened infringement of the Licensed Patent Rights solely owned by IMMUNOGEN under this Agreement, with legal counsel of its own choice. GENENTECH shall have the right, at its own expense, to be represented in any such action by IMMUNOGEN by counsel of GENENTECH’s own choice; provided, however, that under no circumstances shall the foregoing affect the right of IMMUNOGEN to control the suit as described in the first sentence of this Section 6.4(a). If IMMUNOGEN does not file any action or proceeding against such infringement within [***] days after the later of (i) IMMUNOGEN’s notice to GENENTECH under Section 6.3 above, (ii) GENENTECH’s notice to IMMUNOGEN under Section 6.3 above, or (iii) a written request from GENENTECH to take action with respect to such infringement, then GENENTECH shall have the right (but not the obligation), at its own expense, to bring suit (or take other appropriate legal action) against such actual, alleged or threatened infringement, with legal counsel of its own choice. IMMUNOGEN shall have the right, at its own expense, to be represented in any such action by GENENTECH by counsel of IMMUNOGEN’s own choice. Any damages, monetary awards or other amounts recovered, whether by judgment or settlement, pursuant to any suit, proceeding or other legal action taken under this Section 6.4(a), shall first be applied to reimburse the costs and expenses (including attorneys’ fees) of the Party bringing such suit or proceeding or taking such other legal action, then to the costs and expenses (including attorneys’ fees), if any, of the other Party. Any amounts remaining shall be allocated as follows: (A) if GENENTECH is the Party bringing such suit or proceeding or taking such other legal action, [***] percent ([***]%) to GENENTECH and [***] percent ([***]%) to IMMUNOGEN, (B) if IMMUNOGEN is the Party bringing such suit or proceeding or taking such other legal action, [***] percent ([***]%) to IMMUNOGEN and (C) if the suit is brought jointly, [***] percent ([***]%) to each Party. If a Party brings any such action or proceeding hereunder, the other Party agrees to be joined as party plaintiff if necessary to prosecute such action or proceeding, and to give the Party bringing such action or proceeding reasonable assistance and authority to file and prosecute the suit; provided, however,

that neither Party shall be required to transfer any right, title or interest in or to any property to the other Party or any Third Party to confer standing on a Party hereunder.

(b) Infringement of Joint Inventions. As to the any actual, alleged or threatened infringement of any Patent Rights jointly owned by IMMUNOGEN and GENENTECH under this Agreement, including actions against any alleged infringer, the Parties hereto will consult with each other in good faith regarding the best manner in which to proceed. The Parties agree as a basic principle that in the case of such actions against infringers, the expenses incurred and damages awarded shall be for the account of the Party or Parties who take such actions to the extent of their financial participation therein.

6.5 Third Party Patents. If any Third Party claims that a patent it owns or controls claims any aspect of a Licensed Product or its manufacture, use or sale, the Party with notice of such claim shall notify the other Party promptly, and the Parties shall as soon as practicable thereafter discuss in good faith regarding the best response.

6.6 Trademarks. All Licensed Products shall be sold under one (1) or more trademarks and tradenames selected and owned by GENENTECH (or its Sublicensee) in the Territory. GENENTECH (or its Sublicensee) shall control the preparation, prosecution and maintenance of applications related to all such trademarks and tradenames in the Territory, at its sole cost and expense and at its sole discretion. IMMUNOGEN shall notify GENENTECH promptly upon learning of any actual, alleged or threatened infringement of a trademark or tradename applicable to a Licensed Product in the Territory, or of any unfair trade practices, trade dress imitation, passing off of counterfeit goods, or like offenses in the Territory. All of the costs, expenses and legal fees in bringing, maintaining and prosecuting any action to maintain, protect or defend any owned by GENENTECH (or its Sublicensee) hereunder, and any damages or other recovery, shall be GENENTECH’s (or its Sublicensee’s) sole responsibility, and taken in its sole discretion.

6.7 Integration; Survival. This Section 6 supersedes any provisions to the contrary in the HER2 License Agreement and that certain [***] Process Development Agreement by and between the Parties dated as of [***]. This Section 6 shall survive termination or expiration of this Agreement.

7. TERM AND TERMINATION

7.1 Term; Expiration. The term of this Agreement (“Term”) shall expire upon the expiration of the final royalty payment obligation under Section 4.4 above. Upon such expiration of the Term of this Agreement, GENENTECH shall have a fully paid-up, irrevocable, freely transferable and sublicensable license in the Territory under the Licensed Patent Rights and Licensed Technology, to Develop, have Developed, make, have made, use, have used, sell, have sold, offer for sale, import and have imported any and all Licensed Products in the Territory.

7.2. Termination. Subject to the other terms of this Agreement:

(a) Breach. A Party may terminate this Agreement and the licenses granted herein, effective upon written notice to the other Party, upon any breach by the other Party of any material obligation or condition of this Agreement, which material breach remains uncured [***] days after the non-breaching Party gives a first written notice to the other Party describing such breach in reasonable detail; provided, however, that in the event of a [***] by [***] under this Agreement, the [***] shall be [***] (in lieu of [***]) but the other terms of this Section 7.2(a) shall apply to termination in connection with any such payment breach. Notwithstanding anything set forth herein, if the asserted material breach is cured or shown to be non-existent within the applicable cure period, the first notice of breach hereunder shall be deemed automatically withdrawn and of no effect.

(b) Bankruptcy. A Party may terminate this Agreement, effective on written notice to the other Party, in the event the other Party shall have become insolvent or bankrupt, or shall have made an assignment for the benefit of its creditors, or there shall have been appointed a trustee or receiver of the other Party or for all or a substantial part of its property, or any case or proceeding shall have been commenced or other action taken by or against the other Party in bankruptcy or seeking reorganization, liquidation, dissolution, winding-up, arrangement, composition or readjustment of its debts or any other relief under any bankruptcy, insolvency, reorganization or other similar act or law of any jurisdiction now or hereafter in effect, or there shall have been issued a warrant of attachment, execution, distraint or similar process against any substantial part of the property of the other Party, and any such foregoing events shall have continued for [***] days undismissed, unbonded and undischarged. Furthermore, all rights and licenses granted under this Agreement are, and shall be deemed to be, for purposes of Section 365(n) of the United States Bankruptcy Code, licenses of rights to “intellectual property” as

defined under Section 101(56) of the United States Bankruptcy Code. The Parties agree that in the event of the commencement of a bankruptcy proceeding by or against one Party hereunder under the United States Bankruptcy Code, the other Party shall be entitled to complete access to any such intellectual property, and all embodiments of such intellectual property, pertaining to the rights granted in the licenses hereunder of the Party by or against whom a bankruptcy proceeding has been commenced, subject, however, to payment of the milestone amounts and royalties set forth in this Agreement through the effective date of any termination hereunder.

(c) Unilateral Termination by GENENTECH. GENENTECH, in its sole discretion, at any time may terminate this Agreement, and the rights and obligations hereunder, or may remove any Licensed Product and the licenses related thereto from operation of this Agreement, in any case effective [***] days after written notice thereof to IMMUNOGEN. In the event of any termination under this Section 7.2(c) only as to a Licensed Product, the consequences set forth in Section 7.3 below relating to termination of the Agreement under this Section 7.2(c) shall apply only with respect to such terminated Licensed Product, and this Agreement and the rights and obligations hereunder shall continue in full force and effect as to any and all other Licensed Products.

7.3 Effects of Termination. Upon any termination of this Agreement by IMMUNOGEN under Section 7.2(a) or by GENENTECH under Section 7.2(c), as of the effective date of such termination, all relevant licenses and sublicenses granted by IMMUNOGEN to GENENTECH hereunder shall terminate automatically. Notwithstanding the foregoing, (a) no such termination of this Agreement shall be construed as a termination of any valid sublicense of any Sublicensee hereunder, and thereafter each such Sublicensee shall be considered a direct licensee of IMMUNOGEN, provided that (i) such Sublicensee is then in full compliance with all terms and conditions of its sublicense, (ii) all accrued payments obligations to IMMUNOGEN have been paid, and (iii) such sublicensee agrees at least ten (10) days prior to the effective date of such termination to assume all obligations of GENENTECH under this Agreement, and (b) GENENTECH and its Sublicensees shall have the right, for [***] ([***]) months or such longer time period (if any) on which the Parties mutually agree in writing, to sell or otherwise dispose of all Licensed Products then on hand, with royalties to be paid to IMMUNOGEN on all Net Sales of such Licensed Products as provided for in this Agreement. Nothing set forth in this Section 7 or any other provision of this Agreement shall entitle

IMMUNOGEN to any ownership interest in, or to any license under or other rights with respect to (including any rights to use or request any transfer to IMMUNOGEN or any Third Party), any Confidential Information of GENENTECH or any Technology or Patent Rights solely owned by GENENTECH under this Agreement.

7.4 Effects of Termination For IMMUNOGEN Breach. Upon any termination of this Agreement by GENENTECH under Section 7.2(a), as of the effective date of such termination, GENENTECH thereafter automatically shall have a fully sublicensable and transferable, fully paid up (subject to the remainder of this Section 7.4), exclusive license in the Territory under the Licensed Patent Rights and Licensed Technology, to Develop, have Developed, make, have made, use, have used, sell, have sold, offer for sale, import and have imported any and all Licensed Products in the Territory, provided that GENENTECH shall pay, for the remainder of the royalty term under Section 4.4 above, [***] of any payments including milestones or royalties it would [***] to IMMUNOGEN under this Agreement, a [***] equal to [***] of the [***] that would [***] with respect to the Licensed Product under Sections 4.2.1, 4.2.2, 4.2.3 and 4.2.4 of this Agreement.

7.5 Remedies. Except as otherwise expressly set forth in this Agreement, the termination provisions of this Section 7 are in addition to any other relief and remedies available to either Party at law.

7.6 Surviving Provisions. Notwithstanding any provision herein to the contrary, the rights and obligations of the Parties set forth in Sections 4.7, 5, 6, 7.3, 7.4, 7.5, 8, 9, 10 and this Section 7.6, as well as any rights or obligations otherwise accrued hereunder (including any accrued payment obligations), shall survive the expiration or termination of the Term of this Agreement. Without limiting the generality of the foregoing, GENENTECH shall have no obligation to make any milestone or royalty payment to IMMUNOGEN that has not accrued prior to the effective date of any termination of this Agreement, but shall remain liable for all such payment obligations accruing prior to the effective date of such termination.
