In the event that such average per unit sale price cannot be determined for the Licensed Product, on the one hand, and all other product(s) included in the Combination, on the other, Net Sales for the purposes of determining royalty payments shall be mutually agreed upon by the Parties based on the relative value contributed by each component, such agreement to be negotiated in good faith.

The weighted average per unit sale price for both the Licensed Product, on the one hand, and all other product(s) included in the Combination, on the other, shall be calculated once each Calendar Year and such price shall be used during all applicable royalty reporting periods for the entire following Calendar Year. When determining the weighted average per unit sale price of a Licensed Product, other product(s), or Combination, the weighted average per unit sale price shall be calculated by dividing sales dollars (translated into U.S. Dollars using the CytomX Standard Exchange Rate Methodology) by the units sold during the twelve (12) months (or the number of months in which sales occurred in a partial Calendar Year) of the preceding Calendar Year for the respective Licensed Product, other product(s), or Combination. In the initial Calendar Year, a forecasted weighted average per unit sale price will be used for the Licensed Product, other product(s), or Combination. Any over- or under-payment due to a difference between the forecasted and actual weighted average per unit sale price will be paid or credited in the first royalty payment of the following Calendar Year.

3.2.1.Retained Rights. Subject to the other terms of this Agreement (including, without limitation, Section 3.2.2 and 3.3 hereof), ImmunoGen retains the right to use the unpatented Licensed Know-How and practice the Licensed Patent Rights (a) to develop, make, have made, use, sell, offer for sale, import or otherwise commercialize any product (excluding, on a country-by-country basis, while the exclusive license granted under Section 3.1.1 hereof remains in effect in such country, any PDC that Targets the Licensed Target), and to grant licenses to Third Parties to do the same; and (b) for any and all uses outside of the Field.

4.2.3.Royalty Adjustments.

(a)Third Party Royalty Offset. Subject to Section 4.2.3(e) hereof, if, with respect to a Calendar Quarter, CytomX or any of its Affiliates or Sublicensees actually makes royalty payments to one or more Third Parties in consideration of a license, in the absence of which CytomX could not practice the Licensed Intellectual Property to make, offer for sale, sell or import the Cytotoxic Compound portion or Linker portion of any Licensed Product included within the Licensed Intellectual Property (excluding any Licensed Intellectual Property jointly owned by ImmunoGen or its Affiliates, on the one hand, and CytomX or its Affiliates, on the other hand) without infringing an issued patent or patents owned or exclusively licensed by such Third Party in any country (collectively, “Third Party Payments”), as evidenced, to the extent requested by ImmunoGen, by an opinion of Independent Patent Counsel selected by CytomX and approved by ImmunoGen (which approval shall not be unreasonably withheld), then CytomX shall have the right to reduce the royalties otherwise due to ImmunoGen pursuant to Section 4.2.1, 4.2.3(c) or 4.2.3(d) hereof (but not the royalties otherwise due to ImmunoGen pursuant to Section 4.2.3(b) hereof) with respect to Net Sales in such country of such Licensed Products in such Calendar Quarter by an amount equal to fifty percent (50%) of the amount of such Third Party Payments. For purposes of clarity, the term “Third Party Payments” includes only prospective running royalties payable on the same basis as required by this Section 4.2, and does not include any lump-sum license fees, milestone payments, minimum royalties in excess of accrued royalties, any amounts paid for past infringement of any Third Party’s rights or any amount paid for rights not required to permit CytomX to practice the Licensed Intellectual Property to make, use, offer for sale, sell or import the Cytotoxic Compound portion or Linker portion of any Licensed Product included in the Licensed Intellectual Property in any country. For the avoidance of doubt, the Parties agree and acknowledge that this Section 4.2.3(a) shall not apply with respect to royalties payable by a Party to any Third Party under any agreement in existence as of the Effective Date.

(b)Valid Claim Coverage.

(i)No Patent Coverage. Subject to Section 4.2.3(e) hereof, the royalty rates set forth in Sections 4.2.1, 4.2.3(c) and 4.2.3(d) hereof shall apply, on a country-by-country basis and Licensed Product-by-Licensed Product basis, to Net Sales of Licensed Products only where (A) such Licensed Product (or its manufacture, use, sale, offer for sale or importation) in such country is Covered by a Valid Claim within the Licensed Patent Rights or (B) such Licensed Product (or any component or intermediate thereof) was manufactured in a country where the manufacture of such Licensed Product (or such component or intermediate), was, at the time of its manufacture, Covered by a Valid Claim within the Licensed Patent Rights, regardless of the country in which such Licensed Product is sold. Subject to the other terms of this Agreement (except for Section 4.2.3(a) hereof, which shall not apply), on a country-by-country and Licensed Product-by-Licensed Product basis where and as of and when the royalty rates under Sections 4.2.1, 4.2.3(c) and 4.2.3(d) hereof do not apply as a result of this Section 4.2.3(b)(i), the royalties payable with respect to Net Sales of such Licensed Product sold by CytomX, its Affiliates and its Sublicensees in such country shall be reduced by fifty percent (50%) of the royalties otherwise owed to ImmunoGen pursuant to Section 4.2.1 or 4.2.3(d) hereof, as applicable, without giving effect to any royalty reduction provided in Section 4.2.3(c) hereof, using the methodology outlined in Exhibit B attached hereto. The Parties hereby acknowledge and agree that such royalties shall be in consideration of the commercial advantage, know-how and background information gained from the unpatented Licensed Know-How, including, without limitation, ImmunoGen’s Confidential Information and ImmunoGen Proprietary Materials.

(ii)Applicability of Royalty Rates. For purposes of clarity, (A) if a Licensed Product (or its manufacture, use, sale, offer for sale or importation) is Covered by a Valid Claim in a country within the Territory such that royalties are paid by CytomX pursuant to Section 4.2.1, 4.2.3(c) or 4.2.3(d) hereof and, prior to the expiration of the Royalty Term for such Licensed Product in such country, the Licensed Product (and its manufacture, use, sale, offer for sale or importation) is no longer Covered by a Valid Claim in such country, CytomX shall pay ImmunoGen a royalty at the rate set forth in Section 4.2.1(b)(i) hereof for the portion of the Royalty Term during which no such Valid Claim Covers such Licensed Product (or its manufacture, use, sale, offer for sale or importation) in such country; and (B) if a Licensed Product (or its manufacture, use, sale, offer for sale or importation) is not Covered by a Valid Claim in a country

within the Territory such that royalties are paid by CytomX pursuant to Section 4.2.1(b)(i) hereof and, prior to the expiration of the Royalty Term for such Licensed Product in such country, the Licensed Product (or its manufacture, use, sale, offer for sale or importation) becomes Covered by a Valid Claim within the Licensed Patent Rights in such country, CytomX shall pay ImmunoGen a royalty at the rates set forth in Section 4.2.1, 4.2.3(c) or 4.2.3(d) hereof, as applicable, for that portion of the Royalty Term during which such Valid Claim Covers such Licensed Product (or its manufacture, use, sale, offer for sale or importation) in such country.

(iii)Definition of “Cover”. A Valid Claim within the Licensed Patent Rights “Covers” the Licensed Product (or its manufacture, use, sale, offer for sale or importation) in a country if, but for the license granted under Section 3.1.1 hereof, the manufacture, use, sale, offer for sale or importation of the Licensed Product by CytomX or any of its Affiliates or Sublicensees in such country would infringe such Valid Claim; provided, however, that in determining whether a Valid Claim within such Licensed Patent Rights “Covers” (as defined above) the Licensed Product (or its manufacture, use, sale, offer for sale or importation), (A) any Valid Claim within the Licensed Patent Rights that is jointly owned by CytomX (or any of its Affiliates) with ImmunoGen (or any of its Affiliates) shall be deemed to be owned solely by ImmunoGen or an Affiliate of ImmunoGen and (B) any Valid Claim contained in an unissued patent application within the Licensed Patent Rights that has not been (1) canceled, withdrawn or abandoned or (2) pending for more than seven (7) years from its earliest priority date shall be deemed to have been issued.

(c)Loss of Market Exclusivity. Subject to Section 4.2.3(e) hereof, if, with respect to a Calendar Quarter, CytomX or any of its Affiliates or Sublicensees experiences a Loss of Market Exclusivity for a Licensed Product in any country, then CytomX shall have the right to reduce the royalties otherwise due to ImmunoGen pursuant to Section 4.2.1 or 4.2.3(d) hereof (but not the royalties otherwise due to ImmunoGen under Section 4.2.3(b) hereof) with respect to Net Sales in such country of such Licensed Products in such Calendar Quarter as described below, in each case using a methodology similar to that outlined in Exhibit B attached hereto. In calculating royalty reductions pursuant to this Section 4.2.3(c), the applicable WARR (as defined in Exhibit B) shall be multiplied by a percentage which is equal to a fraction, the numerator of which is the actual Net Sales of the Licensed Product in the country for the applicable Calendar Quarter during the period of Loss of Market Exclusivity, and the denominator of which is the Baseline Net Sales of the Licensed Product in 

32

such country; provided, however, that (i) if the percentage referred to above is greater than eighty percent (80%), no reductions shall be made pursuant to this Section 4.2.3(c) with respect to Net Sales of the Licensed Product in such country for such Calendar Quarter; and (ii) such percentage shall never be less than fifty percent (50%), regardless of whether Net Sales of such Licensed Product in such country for such Calendar Quarter are less than fifty percent (50%) of the applicable Baseline Net Sales.

(d)Effect of Challenge. In further consideration of the grant by ImmunoGen of the license hereunder and except to the extent the following is unenforceable under the Applicable Laws of a particular jurisdiction where a patent application within the Licensed Patent Rights is pending or a patent within the Licensed Patent Rights is issued, if CytomX, its Affiliates or Sublicensees initiates a Challenge or induces or assists a Third Party in initiating or prosecuting a Challenge (the Licensed Patent Rights subject to such Challenge being referred to herein as the “Challenged Patent Rights”), then during the period that such Challenge is pending, the royalty rates set forth in Section 4.2.1 hereof shall be increased by an additional two percent (2%) of annual Net Sales (the “Challenge-Related Royalty Increase”) in the country(ies) in which the Challenged Patent Rights were pending or issued (each, a “Challenge Jurisdiction”) commencing on the date of such initiation or the date CytomX, its Affiliates or Sublicensees first induces or provides assistance to such Third Party, as applicable, but only with respect to Net Sales of Licensed Products in the applicable Challenge Jurisdiction(s). If, following the final, unappealable conclusion of a Challenge in a Challenge Jurisdiction, there remains one or more Valid Claims within the Challenged Patent Rights that would be infringed by the manufacture, use, sale, offer for sale or importation then (i) the royalty rates set forth in Section 4.2.1 hereof shall be increased by an additional three percent (3%) of annual Net Sales (which shall be in addition to the Challenge-Related Royalty Increase) in the applicable Challenge Jurisdiction, commencing upon the final, unappealable conclusion of such Challenge and continuing for the remainder of the Royalty Term in the applicable Challenge Jurisdiction, and (ii) CytomX shall reimburse ImmunoGen for its costs and expenses (including, without limitation, reasonable attorneys’ and experts’ fees and expenses of litigation) incurred in responding to the Challenge. CytomX shall be required to pay such reimbursement within sixty (60) days of receiving an invoice therefor from ImmunoGen, which shall set forth in reasonable detail the basis for the charges for which ImmunoGen is seeking reimbursement. If, following the final, unappealable conclusion of a Challenge in a Challenge Jurisdiction, there remain no Valid Claims within the Challenged Patent Rights that would be infringed by the manufacture, use, sale, offer for sale or importation of Licensed Products by CytomX or any of its Affiliates or Sublicensees in such Challenge Jurisdiction in the absence of the license granted under Section 3.1.1 hereof, then ImmunoGen shall reimburse 

33

Confidential Treatment Requested by CytomX Therapeutics, Inc.

 

CytomX for all amounts with respect to the Challenge-Related Royalty Increase actually paid by CytomX to ImmunoGen with respect to the Challenge Jurisdiction (the “Clawback Amount”) as follows: (A) CytomX shall be entitled to credit one hundred percent (100%) of each royalty payment due under Section 4.2 hereof as they become due from and after the final, unappealable conclusion of such Challenge in such Challenge Jurisdiction against the Clawback Amount until reimbursed in full; and (B) any unreimbursed portion of the Clawback Amount outstanding at the conclusion of the Royalty Term in all countries and jurisdictions in the Territory shall be paid to CytomX within sixty (60) days after receipt by ImmunoGen of an invoice from CytomX therefor.

(e)Minimum Royalty Rate. Anything contained in this Agreement to the contrary notwithstanding, none of the reductions to royalties provided in Sections 4.2.3(a), 4.2.3(b) and 4.2.3(c) hereof, shall, individually or in the aggregate, reduce the royalties payable with respect to Net Sales of any Licensed Product sold by CytomX, its Affiliates and its Sublicensees in any country during the Royalty Term by more than fifty percent (50%) of the royalties otherwise owed to ImmunoGen pursuant to Section 4,2.1 or 4.2.3(d), as applicable, without giving effect to any royalty reduction provided in Section 4.2.3(a), 4.2.3(b) or 4.2.3(c) hereof.

4.3Reports and Payments.

4.3.1.Cumulative Royalties. The obligation to pay royalties under Section 4.2 shall be imposed only once with respect to a single unit of a Licensed Product regardless of how many Valid Claims in Patent Rights included within the Licensed Intellectual Property would, but for this Agreement, be infringed by the use or sale of such Licensed Product in the country in which such Licensed Product is used or sold.

4.3.2.Royalty Statements and Payments. Within sixty (60) days after the end of each Calendar Quarter, CytomX shall deliver to ImmunoGen a report setting forth for such Calendar Quarter the following information, on a Licensed Product-by-Licensed Product basis: (a) the gross sales (if available) and the Net Sales of each Licensed Product (specifying in reasonable detail the deductions to gross sales used to calculate Net Sales, (b) the basis for any adjustments to the royalty payable for the sale of each Licensed Product, (c) the applicable exchange rate to convert each country’s currency to U.S. Dollars under Section 4.3.4 hereof and (d) the royalties due hereunder for the sale of each Licensed Product. No such reports shall be due for any Licensed Product before the First Commercial Sale of such Licensed Product in the Territory. The total royalty due for the sale of Licensed Products during such Calendar Quarter shall be remitted at the time such report is delivered.

4.3.3.No Set-Off; Taxes and Withholding. All payments made by CytomX to ImmunoGen hereunder shall be made without set-off or counterclaim and free and clear of any taxes, duties, levies, fees or charges, except withholding taxes, if any. In the event any of the payments made pursuant to this Agreement become subject to withholding taxes under the Applicable Law of any jurisdiction, CytomX shall deduct and withhold the amount of such taxes for the account of ImmunoGen, to the extent required by Applicable Law, such amounts payable to ImmunoGen shall be reduced by the amount of taxes deducted and withheld, and CytomX shall pay the amounts of such taxes to the proper Governmental Authority in a timely manner and promptly transmit to ImmunoGen an official tax certificate or other evidence of such tax obligations together with proof of payment from the relevant Governmental Authority of all amounts deducted and withheld sufficient to enable ImmunoGen to claim such payment of taxes. Any such withholding taxes required under Applicable Law to be paid or withheld shall be an expense of, and borne solely by, ImmunoGen. CytomX will provide ImmunoGen with reasonable assistance to enable ImmunoGen to recover such taxes as permitted by Applicable Law.

4.3.4.Currency. All amounts payable and calculations hereunder shall be in United States dollars, and all payments due under this Agreement shall be made by wire transfer in immediately available funds to an account designated by the Party owed such payment. As applicable, Net Sales and any royalty deductions shall be converted into United States dollars in accordance with the CytomX Standard Exchange Rate Methodology.

4.3.5.Overdue Payments. Subject to the other terms of this Agreement, any payments hereunder not paid within the applicable time period set forth herein shall bear interest from the due date until paid in full, at a rate per annum equal to the lesser of (a) one and one-half percent (1-1/2%) 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 shall be due until such dispute is resolved and the interest that shall be payable thereon shall 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 shall be accompanied by all interest so accrued. Such interest and the payment and acceptance thereof shall 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.

4.4Maintenance of Records; Audits.

4.4.1.Record Keeping. CytomX shall keep, and cause its Affiliates and Sublicensees to keep, accurate books of account and records in connection with the sale of Licensed Products, in sufficient detail to permit accurate determination of all figures necessary for verification of royalties to be paid hereunder. CytomX shall maintain, and cause its Affiliates and Sublicensees to maintain, such records for a period of at least three (3) years after the end of the Calendar Year in which they were generated.

4.4.2.Audits. Upon thirty (30) days prior written notice from ImmunoGen, CytomX shall permit an independent certified public accounting firm of internationally recognized standing selected by ImmunoGen and reasonably acceptable to CytomX to examine, at ImmunoGen’s sole expense, the relevant books and records of CytomX, 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 CytomX in accordance with Section 4.3 hereof and the payment of royalties hereunder. An examination by ImmunoGen under this Section 4.4.2 shall occur not more than once in any Calendar Year and shall be limited to the pertinent books and records for any Calendar Year ending not more than three (3) years before the date of the request. The accounting firm shall be provided access to such books and records at the facilities where such books and records are kept and such examination shall be conducted during normal business hours. CytomX may require the accounting firm to sign a reasonable and customary non-disclosure agreement before providing the accounting firm access to CytomX’s facilities or records. Upon completion of the audit, the accounting firm shall provide both ImmunoGen and CytomX a written report disclosing whether the reports submitted by CytomX are correct or incorrect, whether the royalties paid are correct or incorrect and, in each case, the specific details concerning any discrepancies. CytomX and ImmunoGen shall each have the right to request a further determination by such accounting firm as to matters which such Party disputes within thirty (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 shall undertake to complete such further determination within thirty (30) days after the dispute notice is provided, which determination shall be limited to the disputed matters and provided to both Parties. The Parties shall 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, shall be binding on both Parties.

4.4.3.Underpayments/Overpayments. If such accounting firm concludes that additional royalties were due to ImmunoGen, CytomX shall pay the additional royalties (plus interest thereon at the rate provided in Section 4.3.5 hereof) within forty-five (45) days of the date CytomX receives such accountant’s written report so concluding. If such underpayment exceeds five percent (5%) of the royalties that

were to be paid and is also greater than Fifty Thousand U.S. Dollars ($50,000), CytomX also shall reimburse ImmunoGen for all reasonable charges of such accountants for conducting the audit. If such accounting firm concludes that CytomX overpaid royalties, ImmunoGen shall repay such amount in full within forty-five (45) days of the receipt of such accountant’s report, or, at CytomX’s option, it shall be entitled to offset all such overpayments against any outstanding or future amounts payable to ImmunoGen hereunder until CytomX has received full credit for such overpayments.

5.2Filing, Prosecution and Maintenance of Patent Rights.

5.2.1.Cooperation. Without limiting any other rights and obligations of the Parties under this Agreement, the Parties shall cooperate with respect to the timing, scope and filing of patent applications and patent claims relating to any Joint Program Technology to preserve and enhance the patent protection for Licensed Products, including the manufacture and use thereof and to allow the Party owning the technology underlying an Improvement to have reasonable input to preserve and enhance its patent portfolio and patenting strategy.

5.2.2.ImmunoGen Patent Rights. ImmunoGen, at its own expense, shall have the sole right, but not the obligation, to prepare, file, prosecute and maintain, throughout the world, all Licensed Patent Rights (other than Licensed Patent Rights claiming Joint Program Technology or Joint TAP Platform Improvements). With respect to any Licensed Patent Rights disclosing or claiming Program Technology (other than TAP Platform Improvements included in the Program Technology), ImmunoGen shall keep CytomX reasonably informed of the status of the filing, prosecution and maintenance of such Patent Rights and shall consider in good faith any recommendations made by CytomX in regard to the filing, prosecution or maintenance of any such Patent Right. ImmunoGen shall consult with CytomX in the filing, prosecution and maintenance of any ImmunoGen Patent Right related to Improvements to CytomX Technology and shall not unreasonably refuse to incorporate any recommendations made by CytomX in regard to such filing, prosecution or maintenance. To the extent ImmunoGen decides not to file, prosecute or maintain any Licensed Patent Right that ImmunoGen reasonably believes covers or may cover the Development, Manufacture, Commercialization or use of any Licensed Product (other than any such Patent Right owned or co‐owned by a Third Party licensor or the filing of a new initial patent application) and except in the case in which the decision not to file, prosecute or maintain such Patent Right is made by ImmunoGen in the ordinary course of filing continuation

applications or as part of an overall strategy to optimize the scope or other aspects of the Licensed Intellectual Property, ImmunoGen shall provide CytomX with thirty (30) days prior written notice to such effect (i.e., at least thirty (30) days prior to the date on which any such filing is intended or due or on which any other such action is due), in which event CytomX may elect to file or continue prosecution or maintenance of such Patent Right, at CytomX’s expense, and ImmunoGen, upon CytomX’s written request received within such thirty (30) day period, shall execute such documents and perform such acts, at CytomX’s expense, as may be reasonably necessary to permit CytomX to file, prosecute and maintain such Patent Right; provided that CytomX (a) shall keep ImmunoGen reasonably informed of the status of the filing, prosecution and maintenance of such Patent Rights, (b) shall consider in good faith any recommendations made by ImmunoGen in regard to such filing, prosecution and maintenance of such Patent Right, and (c) shall not unreasonably refuse to incorporate any recommendations made by ImmunoGen in regard to such filing, prosecution or maintenance. Any such Patent Right that is prosecuted or maintained by CytomX pursuant to this Section 5.2.2 (a) will continue to be owned by ImmunoGen, and (b) subject to the Parties’ other rights and obligations under this Agreement, may be licensed by ImmunoGen to one or more Third Parties. For avoidance of doubt, “prosecution” as used in this Section 5.2 includes oppositions, nullity or revocation actions, post-grant reviews and other patent office proceedings involving the referenced Patent Rights.

5.2.3.CytomX Patent Rights. CytomX, at its own expense, shall have the sole right, but not the obligation, to prepare, file, prosecute and maintain, throughout the world, any Patent Rights comprised in the CytomX TAP Platform Improvements. CytomX shall consult with ImmunoGen in the filing, prosecution and maintenance of any Patent Right related to CytomX TAP Platform Improvements (including, without limitation, keeping ImmunoGen reasonably informed of the status thereof), shall consider in good faith any recommendations made by ImmunoGen in regard to such filing, prosecution or maintenance, and shall not unreasonably refuse to incorporate any recommendations made by ImmunoGen in regard to such filing, prosecution or maintenance. Nothing contained in this Agreement shall be construed as obligating CytomX to file any patent application in any country or other jurisdiction relating to CytomX TAP Platform Improvements.

5.2.4.Joint Patent Rights. If not already established under the Research Collaboration Agreement, prior to either Party filing any Patent Right disclosing Joint Program Technology or Joint TAP Platform Improvements, the Parties shall establish a patent committee (the “Patent Committee”) comprised of at least one (1) representative of each Party for the purpose of facilitating the preparation, filing, prosecution, maintenance and defense of Joint Patent Rights. As agreed upon by the Parties, meetings of the Patent Committee may be face-to-face or may be conducted by teleconferences or videoconferences, from time to time as needed. The Patent Committee will be the forum through which the Parties coordinate their respective obligations to each other described in Sections 5.2.2 and 5.2.3 hereof and in this Section. In the event the Parties conceive or generate any Joint Program

Technology or Joint TAP Platform Improvements, the Parties shall promptly meet to discuss and determine, based on mutual consent, whether to seek patent protection thereon, which Party will control filing, prosecution and maintenance of such patents and how to pay for the filing, prosecution and maintenance of such patents. It is presumed that CytomX will control filing, prosecution and maintenance of Joint Patent Rights claiming Joint Program Technology or Joint Unconjugated Probody Platform Improvements, and that ImmunoGen will control filing, prosecution and maintenance of Joint Patent Rights claiming Joint TAP Platform Improvements or Joint Conjugation Probody Platform Improvements. Neither Party will file any Joint Patent Right without the prior written consent of the other Party, which consent shall not be unreasonably withheld, conditioned or delayed. The Party controlling filing and prosecution of any such Joint Patent Right (a) shall keep the other Party informed regarding each Patent Right, (b) shall consider in good faith any recommendations made by the other Party in regard to the filing, prosecution or maintenance of any such Patent Right and (c) shall not unreasonably refuse to incorporate any recommendations made by the other Party in regard to such filing, prosecution or maintenance.

5.2.5.Improper Patent Filings. Each Party agrees that, without the prior written consent of the other Party, neither it nor any of its Affiliates will claim in any patent application filed by or on behalf of such Party (or its Affiliate) any unpatented, nonpublic invention for which the inventor(s) (alone or with others) are employees of, or other persons obligated to assign inventions to, the other Party or any Affiliate of the other Party, or disclose any such invention in any such patent application in a manner that would prejudice the other Party’s ability to patent such invention.

5.2.6.Liability. Except for breaches of Section 5.2.5 hereof, to the extent that a Party is obtaining, prosecuting or maintaining a Patent Right included in the Licensed Intellectual Property or Joint Patent Rights or otherwise exercising its rights under this Section 5.2, such Party, and its Affiliates, employees, agents or representatives, shall not be liable to the other Party in respect of any act or omission on the part of any such Party, or its Affiliates, employees, agents or representatives, in connection with such activities undertaken in good faith.

5.2.7.Extensions. The decision to file for a patent term extension and particulars thereof (including which patent(s) to extend) will be made with the goal of obtaining the optimal patent term and scope of protection for Licensed Products. If a Party wishes to file for a patent term extension based on Patent Rights owned by the other Party, it will so notify the other Party, and the Parties will meet to discuss and determine whether and how to proceed with such patent term extension.

5.3Joint Research Agreement. This Agreement shall be understood to be a joint research agreement under 35 U.S.C. § 103(c)(3) entered into for the purpose of Developing Licensed Products.

(g)The enforcing Party shall keep the other Party reasonably informed of all material developments in connection with any such suit. Any recoveries obtained by either Party as a result of any proceeding against such a Third Party infringer (“Monies”) shall be allocated as follows:

(i)the Monies will be distributed first to the controlling Party for its out-of-pocket litigation costs and expenses incurred in connection with such litigation; then

(ii)the Monies will then be distributed to the other Party for its out-of-pocket litigation costs and expenses incurred in connection with such litigation; then

(iii)to the extent the remaining Monies recovered represent such Third Party’s infringing sales with respect to Licensed Products, (A) ImmunoGen will receive an amount out of such remaining Monies equal to the royalties that would have been due upon sales of the infringing product as if such infringing sales had been incremental Net Sales of a Licensed Product sold by CytomX (the “Deemed Royalty Portion”), and (B) CytomX will receive the amount of such remaining Monies representing such Third Party’s infringing sales with respect to Licensed Products, minus the Deemed Royalty Portion; or

(iv)to the extent the remaining Monies recovered represent CytomX’s lost profits with respect to Licensed Products, the amount of such Monies shall be grossed up to an amount equivalent to what would have been Net Sales (taking into account CytomX’s costs of manufacture and sale relative to such Third Party’s costs of manufacture and sale) and (A) ImmunoGen will receive the Deemed Royalty Portion of such calculated Net Sales, and (B) CytomX will receive the amount of such remaining Monies representing CytomX’s lost profits with respect to Licensed Products, minus the Deemed Royalty Portion; or

(v)to the extent the remaining Monies recovered represent royalties from sales of a product that infringes (A) any Licensed Patent Rights alone or (B) any Licensed Patent Rights and any other Patent Rights owned by or licensed to CytomX or one of its Affiliates or Sublicensees, and the applicable decision-making authority in the action, suit or proceeding has not allocated the Monies between ImmunoGen and the owner of such other Patent Rights, then the Parties shall agree, in good faith, to an allocation of such Monies based on the relevant contributions of the Licensed Patent Rights and such other Patent Rights to the Licensed Product; provided that if the Parties are unable to agree in good faith as to the

allocation of such Monies on such basis, then the Parties shall submit such matter for determination to an Independent Patent Counsel; provided that the determination of such independent patent counsel shall be final and binding upon the Parties; then

(vi)if CytomX is the controlling Party, then CytomX will retain all Monies remaining after the distributions described in subsections (i) through (v) above, including, without limitation, those for any multiple damages, punitive damages or other non‐compensatory damages, which are applicable to the Licensed Products; or

(vii)if ImmunoGen is the controlling Party, then ImmunoGen will retain all Monies remaining after the distributions described in subsections (i) through (v) above, including, without limitation, those for any multiple damages, punitive damages or other non‐compensatory damages.

(h)Other Infringement. For any infringement of Patent Rights owned by CytomX or licensed by CytomX from Third Parties, CytomX retains the sole right (as between the Parties), but not the obligation, to enforce such Patent Rights.

(i)Infringement of Joint Patent Rights. With respect to any notice of a Third Party infringer of any Joint Patent Right other than a Patent Right included in the Joint Program Technology or Joint TAP Platform improvements, the Parties shall meet as soon as reasonably practicable to discuss such infringement and determine an appropriate course of action and the Parties’ respective rights and responsibilities with respect to any enforcement thereof.

5.5Response to Biosimilar Applicants.

(c)Preparation of CytomX Response. Not later than thirty (30) days from the date of receipt by CytomX of the Applicant Response, CytomX, with cooperation and assistance from ImmunoGen, shall prepare and provide ImmunoGen with a proposed response with respect to the Licensed Patent Rights (the “CytomX Response”) that (i) describes on a claim‐by‐claim basis, how each patent within the Licensed Patent Rights on the Proposed Patent List would be infringed by the commercial marketing of the Proposed Biosimilar Product, and (ii) responds to Applicant’s claims, if any, that the patents within the Licensed Patent Rights on the Proposed Patent List are invalid or unenforceable. The CytomX Response shall include only the foregoing and shall not be construed to include any proposed response to the Applicant relating to any patents other than the Licensed Patent Rights; further, any actual response to the Applicant under the BPCIA and all decisions relating to subsequent procedures under the BPCIA with regard to any patent other than those included within the Licensed Patent Rights shall be within the sole discretion of CytomX. As soon as practicable following the date of receipt by ImmunoGen of the proposed CytomX Response, the Parties shall discuss in good faith the statements in the proposed CytomX Response and CytomX shall consider in good faith ImmunoGen’s proposals for changes to the CytomX Response. Not later than the end of the period specified by Applicable Laws, CytomX shall provide the Applicant with a copy of the CytomX Response; provided, however, that CytomX shall incorporate certain ImmunoGen requests in accordance with Section 5.5.3(d) hereof.

(d)Inclusion of Licensed Patent Rights or Responsive Information.

initial CytomX Response provided to ImmunoGen pursuant to Section 5.5.3(c) hereof, then, absent manifest error, CytomX shall include such patent in the Proposed Patent List and such responsive information in the CytomX Response provided to Applicant, as applicable; provided, however, that ImmunoGen shall indemnify CytomX in accordance with Section 9.2 hereof to the extent any submissions requested by ImmunoGen are determined to have been made negligently or in bad faith.

(e)Negotiation: ImmunoGen Rights. As soon as possible following the date on which CytomX provides the CytomX Response to the Applicant, CytomX shall commence good faith negotiations with Applicant for a period of not more than fifteen (15) days (the “Negotiation Period”) in an effort to reach agreement on the patents on the Proposed Patent List (the “Infringed Patent List”) that will be the subject to an Immediate Patent Infringement Action; provided, however, that if the Proposed Patent List includes both patents within the Licensed Patent Rights and patents that are not within the Licensed Patent Rights, then CytomX shall not agree to the inclusion in the Infringed Patent List of any patents within the Licensed Patent Rights without the prior written consent of ImmunoGen, which consent shall not be unreasonably withheld, conditioned or delayed. If CytomX and Applicant fail to reach agreement under Section 351(1)(4)(A) of the PHSA on the Infringed Patent List, CytomX shall have the sole right to determine under Section 351(1)(5)(B) of the PHSA which patents of those on the Proposed Patent List should be the subject of an Immediate Patent Infringement Action; provided, however, that if the Proposed Patent List includes both patents within the Licensed Patent Rights and patents that are not within the Licensed Patent Rights, then CytomX shall not include in the list of patents to be provided by CytomX to Applicant pursuant to Sections 351(1)(5)(B)(i)(II) of the PHSA any patents within the Licensed Patent Rights without the prior written consent of ImmunoGen, which consent shall not be unreasonably withheld, conditioned or delayed. Within ten (10) days following the exchange of such lists by CytomX and the Applicant, CytomX shall, to the extent legally permissible, provide ImmunoGen with a copy of the portion of the combined Infringed Patent List containing patents within the Licensed Patent Rights that will be the subject of an Immediate Patent Infringement Action.

(f)Supplements to Proposed Patent List. ImmunoGen shall provide CytomX with a copy of any U.S. patent within the Licensed Patent Rights that is issued after CytomX has provided the Proposed Patent List to the Applicant within ten (10) day after such issuance. As soon as practicable following the date of receipt by CytomX of any such patent, ImmunoGen and CytomX shall discuss in good faith whether such patent would be infringed by the manufacture and/or sale of the Proposed Biosimilar Product. CytomX  shall provide the Applicant with a supplement to the Proposed Patent List to include such patent not later than thirty (30) days

Notwithstanding any provision of this Agreement to the contrary, either Party may disclose the existence or terms of this Agreement to the extent required, in the reasonable opinion of such Party’s legal counsel, to comply with Applicable Law. Notwithstanding the foregoing, before disclosing this Agreement or any of the terms hereof pursuant to this Section 6.2.3, the Parties will consult with one another on the terms of this Agreement to be redacted in making any such disclosure. Further, if a Party discloses this Agreement or any of the terms hereof in accordance with this Section 6.2.3, such Party shall, at its own expense, use Commercially Reasonable Efforts to seek such confidential treatment of confidential portions of this Agreement and such other terms, as may be reasonably requested by the other Party.

6.3Public Announcements; Publications.

6.3.1.Announcements. Except as may be expressly permitted under Section 6.2.3, neither Party will make any public announcement regarding the existence or terms of this Agreement without the prior written approval of the other Party. For the sake of clarity, nothing in this Agreement shall 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 shall mutually agree to one or more press releases regarding the signing of this Agreement following the Effective Date. The Parties agree that each Party may issue future announcements concerning CytomX’s achievement of any significant milestones, including the selection of a clinical candidate, under this Agreement, provided that the content of any such announcement has been mutually agreed upon by the Parties.

6.3.2.Publications. The Parties acknowledge that scientific publications and presentations must be strictly monitored to prevent any adverse effect from premature publication or dissemination of results of the activities hereunder. Each Party (in such capacity the “Publishing Party”) agrees that, except as required by Applicable Laws, it shall not publish or present, or permit to be published or presented, any results of the Development, Manufacture, use or Commercialization of a Licensed Product to the extent such results refer to, derive from or otherwise relate to the Licensed Intellectual Property (the “Covered Results”), without the prior review by and approval of the other Party (in such capacity, the “Non‐Disclosing Party”), which approval shall not be unreasonably withheld; provided that it shall not be deemed unreasonable for CytomX to withhold its consent to any request by ImmunoGen to publish or disseminate Covered Results prior to the publication or dissemination of such Covered Results by CytomX. The Publishing Party shall submit to the Non-Disclosing Party for review and approval any proposed academic, scientific and medical publication or public presentation which contains Covered Results or otherwise contains the Non-Disclosing Party’s Confidential Information; provided that the foregoing requirement shall apply to CytomX only to the extent any such proposed publication or presentation would refer to, describe or otherwise disclose Confidential Information of ImmunoGen

(including, without limitation, any nonpublic Licensed Intellectual Property). In addition, each Party shall submit to the other Party for review and approval any proposed publication or public presentation relating to data generated under the Research Program. In both instances, such review and approval will be conducted for the purposes of preserving the value of the Licensed Intellectual Property and determining whether any portion of the proposed publication or presentation containing the Non-Disclosing Party’s Confidential Information should be modified or deleted. Written copies of such proposed publication or presentation required to be submitted hereunder shall be submitted to the Non-Disclosing Party no later than thirty (30) days before submission for publication or presentation (the “Review Period”). The Non-Disclosing Party shall provide its comments with respect to such publications and presentations within fifteen (15) days after its receipt of such written copy, and the Publishing Party shall delete any Confidential Information of the Non-Disclosing Party upon request. The Review Period may be extended for an additional sixty (60) days in the event the Non-Disclosing Party can, within fifteen (15) days of receipt of the written copy, demonstrate reasonable need for such extension, including for the preparation and filing of patent applications. The Parties will each comply with standard academic practice regarding authorship of scientific publications and recognition of contribution of other parties in any publication governed by this Section 6.3.2.

6.3.3.Integration. As to the subject matter of this Agreement, this Article 6 supersedes any confidential disclosure agreements between the Parties, including, without limitation, the Confidentiality Agreement and the confidentiality provisions of the Research Collaboration Agreement. Any confidential information of a Party disclosed under the Confidentiality Agreement or the Research Collaboration Agreement relating to the subject matter of this Agreement shall be treated as Confidential Information of such Party hereunder, subject to the terms of this Article 6.

Information in its archives solely for the purpose of establishing the contents thereof and ensuring compliance with its obligations hereunder, (ii) any Confidential Information of the other Party contained in its laboratory notebooks or databases, and (iii) any Confidential Information of the other Party to the extent reasonably required to exercise its rights and perform its obligations under any other then-outstanding License Agreement,

9.1No Consequential Damages. Except with respect to liability arising from a breach of Article 6 hereof, in no event will either Party, its Affiliates or any of its or its Affiliates’ respective Representatives be liable under this Agreement for any special, indirect, incidental, consequential or punitive or exemplary damages, whether in contract, warranty, tort, negligence, strict liability or otherwise, (a) including loss of profits or revenue suffered by either Party or any of its respective Affiliates or Representatives or (b) cost of procurement of substitute goods, technology or services, even if either Party is informed in advance of the possibility of such damages and even if the remedies provided for in this Agreement fail of their essential purpose. For purposes of clarity, a Party’s monetary liability under a Third Party Claim for such Third Party’s special, indirect, incidental or consequential damages or for any punitive or exemplary damages payable in connection with such Third Party Claim, shall be deemed to be the direct damages of such Party for purposes of this Article 9.

9.2Indemnification by ImmunoGen. ImmunoGen will indemnify, defend and hold harmless CytomX, its Affiliates and each of its and their respective employees, officers, directors and agents (each, a “CytomX Indemnified Party”) from and against any and all liability, loss, damage, expense (including reasonable attorneys’ fees and expenses) and cost (collectively, a “Liability”) as a direct result of any Third Party claims, suits, actions, demands or judgments, including, without limitation, personal injury and product liability matters (collectively, “Third Party Claims”) arising out of a Material Breach of this Agreement by ImmunoGen, except, in each case, to the extent any such Third Party Claim or Liability results from a Material Breach of this Agreement by CytomX, the Development, Manufacture, Commercialization or use (including, without limitation, the production, manufacture, promotion, import, sale or use by any Person) of any Licensed Product by, on behalf of, or under the authority of, CytomX or any of its Affiliates, Sublicensees, subcontractors, distributors or agents (other than an ImmunoGen Indemnified Party), or the negligence, recklessness or intentional acts of CytomX or any of its Affiliates, Sublicensees, subcontractors, distributors or agents; provided that with respect to any Third Party Claim for which CytomX also has an obligation to indemnify any ImmunoGen Indemnified Party pursuant to Section 9.3 hereof, ImmunoGen shall indemnify each CytomX Indemnified Party for its Liability to the extent of ImmunoGen’s responsibility, relative to CytomX (or to Persons for whom CytomX is legally responsible), for the facts underlying the Third Party Claim.

(a)the Development, Manufacture, Commercialization or use (including, without limitation, the production, manufacture, promotion, import, sale or use by any Person) of any Licensed Product by, on behalf of, or under the authority of, CytomX or any of its Affiliates, Sublicensees, subcontractors, distributors or agents (other than by any ImmunoGen Indemnified Party); or

(b)a Material Breach of this Agreement by CytomX; 

except to the extent any such Third Party Claim or Liability results from a Material Breach of this Agreement by ImmunoGen or the negligence, recklessness or intentional acts of ImmunoGen or any ImmunoGen Indemnified Party; provided that with respect to any Third Party Claim for which ImmunoGen also has an obligation to indemnify any CytomX Indemnified Party pursuant to Section 9.2 hereof, CytomX shall indemnify each ImmunoGen Indemnified Party for its Liability to the extent of CytomX’s responsibility, relative to ImmunoGen (or to Persons for whom ImmunoGen is legally responsible), for the facts underlying the Third Party Claim.

9.4Procedure.

9.4.1.Notice. Each Party will notify the other Party in writing in the event it becomes aware of a claim for which indemnification may be sought hereunder. In the event that any Third Party asserts a claim or other proceeding (including any governmental investigation) with respect to any matter for which a Party (the “Indemnified Party”) is entitled to indemnification hereunder, then the Indemnified Party shall promptly notify the Party obligated to indemnify the Indemnified Party (the “Indemnifying Party”) thereof; provided, however, that no delay on the part of the Indemnified Party in notifying the Indemnifying Party shall relieve the Indemnifying Party from any obligation hereunder unless (and then only to the extent that) the Indemnifying Party is prejudiced thereby.

9.4.2.Control. The Indemnifying Party shall have the right, at its sole cost and expense, exercisable by notice to the Indemnified Party within ten (10) Business Days after receipt of notice from the Indemnified Party of the commencement of or assertion of any Third Party Claim, to assume direction and control of the defense, litigation, settlement, appeal or other disposition of the Third Party Claim (including the right to settle the claim solely for monetary consideration) with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party.

records, information and testimony and attending such conferences, discovery proceedings, hearings, trials or appeals as may reasonably be requested by the Indemnifying Party. The Indemnified Party shall have the right to join in (including the right to conduct discovery, interview and examine witnesses and participate in all settlement conferences), but not control, at its own expense, the defense of any Third Party Claim that the other Party is defending as provided in this Agreement.

9.4.3.Settlement. Neither the Indemnifying Party nor the Indemnified Party shall enter into any compromise or settlement of a Third Party Claim for which the right to indemnification hereunder has been asserted without the Indemnified Party’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed; provided that the Indemnifying Party may, without the Indemnified Party’s prior written consent, agree or consent to any settlement or other resolution of such Third Party Claim which requires solely money damages paid by the Indemnifying Party, and which includes as an unconditional term thereof the giving by such claimant or plaintiff to the Indemnified Party of a release from all liability in respect of such Third Party Claim. Each of the Indemnifying Party and the Indemnified Party shall not make any admission of liability in respect of any Third Party Claim without the prior written consent of the other Party, and the Indemnified Party shall use reasonable efforts to mitigate Liabilities arising from such Third Party Claim.

9.5Insurance. Each Party shall obtain and maintain, during the Term, commercial general liability insurance, including products liability insurance, with reputable and financially secure insurance carriers (or pursuant to a program of self-insurance reasonably satisfactory to the other Party) to cover its indemnification obligations under Section 9.2 or 9.3 hereof with respect to bodily injury (including death) and damage to property, as applicable, in each case with limits of not less than $3,000,000 per occurrence and in the aggregate. Insurance (other than permitted self-insurance) shall be procured with carriers having an A.M. Best Rating of A-VII or better. Any indemnification payment hereunder shall be made net of any insurance proceeds which the Indemnified Party is entitled to recover; provided, however, that if, following the payment to the Indemnified Party of any amount under this Article 9, such Indemnified Party becomes entitled to recover any insurance proceeds in respect of the claim for which such indemnification payment was made, the Indemnified Party shall promptly pay an amount equal to the amount of such proceeds (but not exceeding the amount of such indemnification payment) to the Indemnifying Party.

Exhibit B

Royalty Rate Reduction Methodology

Step 1 – Calculate the Weighted Average Royalty Rate (WARR) for the Calendar Quarter

	
•
	
This is the weighted average rate calculated based on the worldwide Net Sales of the Licensed Product for a Calendar Quarter, based upon the rates detailed in Section 4.2 of this Agreement and assuming that there are not any countries where the royalty rate is to be reduced per Section 4.2.3(b)(i) or 4.2.3(c) of this Agreement. (M = Million)

	
o
	
For instance, if the worldwide Net Sales for Calendar Quarter 1 of 2020 is $1,000M, then the WARR for that period is ($500M*[***]% + $500M*[***]%) / $l,000M = [***]%

	
•
	
WARR is the basis for the royalty reduction; it is not the effective royalty rate for a certain country or for the Licensed Product on a worldwide basis.

Step 2 – Determine the reduced royalty due to ImmunoGen for those countries in the world for which a reduced royalty rate is to be applied per Section 4.2.3(b)(i) or 4.2.3(c) of this Agreement.

	
•
	
The reduced royalty rate is the WARR * 50%

	
•
	
Continuing with the example in Step 1,

	
o
	
If Country X is the one (and only) country in the world for which a reduced royalty rate is to be applied per Section 4.2.3(b)(i) or 4.2.3(c) of this Agreement, and 

	
o
	
sales in Country X for the Calendar Quarter are $50M (out of the $1,000M of worldwide sales),

	
o
	
then the reduced royalty due to ImmunoGen for Country X is:

[***]% * 50% * $50M = $[***]

	
•
	
This calculation should be repeated for each country for which a reduced royalty rate is to be applied per Section 4.2.3(b)(i) or 4.2.3(c) of this Agreement.

Step 3 Apply the WARR from Step 1 to Net Sales for the Calendar Quarter in all countries of the world in which the royalty rate is not to be reduced per Section 4.2.3(b)(i) or 4.2.3(c) of this Agreement.

	
•
	
Continuing with the example in Step 1,

	
o
	
Net Sales for the Calendar Quarter excluding Country X are $950M (out of the $1,000M of worldwide sales)

	
o
	
Then the royalties due to ImmunoGen for all countries of the world excluding Country X are:

$500M*[***]% + $450M*[***]% = $[***]

Step 4 – Sum the amounts calculated in Steps 2 and 3 above to arrive at the total royalties due to ImmunoGen for the Calendar Quarter.

	
•
	
Continuing with the example in Step 1,

$[***] +$[***] = $[***]
