The Development Support shall include making its personnel who are knowledgeable of the Compound and Product, its properties, manufacture and Development, reasonably available to Amgen for scientific and technical explanations, advice and on-site support, as may reasonably be required by Amgen, relating to the Development, manufacture and/or registration of the Compound and Products.  Amgen shall reimburse Xencor for the time spent in excess of [...***...] by Xencor personnel providing Development Support requested by Amgen at the rate of $[...***...] per person-hour (the “Development Support Rate”).  Amgen shall reimburse Xencor for the reasonable out-of-pocket expenses incurred by Xencor in providing the Development Support requested by Amgen, provided that Amgen shall not be obligated to reimburse travel expenses of Xencor personnel except to the extent Amgen has approved such travel.  In no event shall Xencor be obligated to provide more than an aggregate of [...***...] person-hours of technical assistance pursuant to this Section 3.7(e), or to provide technical assistance pursuant to this Section 3.7(e) after the Development Support Period, except, in each case, upon mutual written agreement of the Parties.  Notwithstanding the foregoing, if at any time Amgen reasonably requires access to any Xencor Know-How (for example, access to original patient report forms, batch records or the like), Xencor agrees to use commercially reasonable efforts to cooperate with Amgen in effectuating such access even after the expiration of the Development Support Period or following the fulfillment of Xencor’s maximum aggregate hours of the technical assistance described in the preceding sentence; provided that Amgen reimburses Xencor for any out-of-pocket costs incurred by Xencor for such assistance and for any internal personnel time of Xencor at the Development Support Rate.  For clarity, amounts paid by Xencor to non-employee consultants in providing assistance under this Section 3.7(e) shall be deemed out-of-pocket costs.

 

(f)                                   Amgen acknowledges that Xencor’s ability to achieve expeditiously and effectively the transfer of items, information and responsibilities, and to provide the assistance, described above in this Section 3.7 will require the cooperation and close coordination of Amgen, including the availability of appropriately qualified personnel and suitable facilities on a timely basis.  Xencor shall not be responsible for any delay or failure to perform such transfer, or to provide such assistance, to the extent such delay or failure results from Amgen’s failure to provide such cooperation and coordination.

 

3.8                               Development After Option Exercise.

Development Budget, and each annual update thereto pursuant to Section 6.3, will constitute Amgen’s reasonable estimate, as of the date such budget or update is delivered to Xencor, of the actual direct and indirect costs of performance of the Post-Exercise Development Plan (including reasonable provision for contingencies) and will have been prepared in good faith and accordance with fair and reasonable cost accounting practices.  Xencor shall have [...***...] after receipt of the Post-Exercise Development Plan and Post-Exercise Development Budget in which to notify Amgen whether or not Xencor elects to share Development Costs under the Post-Exercise Development Plan in accordance with Section 6.3 (the “Cost Sharing Election Notice”).  If Xencor indicates in its Cost Sharing Election Notice that it does not wish to share any such Development Costs in accordance with Section 6.3, the Co-Funding Arrangement shall be deemed terminated as of the Option Exercise Date and Xencor will not have any right thereafter to reinstate the Co-Funding Arrangement.  If Xencor elects to share such Development Costs in accordance with Section 6.3, the Cost Sharing Election Notice shall also specify whether Xencor elects to share [...***...]%,[...***...]% or [...***...]% (the “Xencor Sharing Percentage”) of Shared Development Costs.  The Xencor Sharing Percentage specified in the Cost Sharing Election Notice shall apply from the Option Exercise Date until the end of the first full calendar year after the Option Exercise Date.  Xencor agrees and acknowledges that Xencor’s failure to provide any such notice within such period shall be deemed to constitute Xencor’s election to share [...***...]% of Shared Development Costs.

 

(b)                                 Conduct of Post-Exercise Development Plan.

Regardless of whether or not Xencor elects to share Development Costs pursuant to this Section 3.8 and Section 6.3, Amgen shall use Commercially Reasonable Efforts to conduct and to complete the Post-Exercise Development Plan, as in effect from time to time.  Amgen shall conduct such activities in accordance with the Post-Exercise Development Plan, in compliance with all Applicable Laws and in accordance with good scientific and clinical practices (including all record keeping requirements).  In addition to the Development Cost reports due pursuant to Section 6.3 (if applicable), Amgen shall provide the DC with a written progress report at least [...***...] before each regularly-scheduled quarterly DC meeting summarizing the Post-Exercise Development Plan activities conducted by or on behalf of Amgen during such calendar quarter, together with a reasonable summary of the results of such activities and the anticipated completion schedule for the remaining activities under the then-current Post-Exercise Development Plan.

 

3.9                               Development; Commercialization.  Subject to the terms and conditions of this Agreement from and after such time as Amgen exercises the Option, Amgen shall have the right to control, and as between the Parties shall be solely responsible (subject to the Co-Funding Arrangement) for the costs associated with, the Development, commercialization, manufacturing, distribution, marketing, promotion and other exploitation of Compounds and Products in the Field in the Territory.  Without limiting the generality of the foregoing, except as expressly set forth in Section 3.7, Amgen shall

5.6                               No Other Rights.  Except for the rights and licenses expressly granted in this Agreement, Xencor retains all rights under its intellectual property, and no additional rights shall be deemed granted to Amgen by implication, estoppel or otherwise.  Without limiting the generality of the foregoing, in no event shall Amgen as a result of this Agreement have any right or license to develop, make, have made, use, sell, have sold, offer for sale or import any compound (including any Excluded Antibody) that is not a Compound.  For clarity, Xencor retains the right at all times during the Term to practice the Xencor Patents and Xencor Know-How for all purposes, except, from the Option Exercise Date and thereafter during the Term, to Develop, make, have made, use, sell, have sold, offer for sale or import the Compound and Products in the Field in the Territory.

 

6.                                      PAYMENTS; BOOKS AND RECORDS

 

6.1                               Upfront Fee.  Amgen shall pay to Xencor a non-refundable, non-creditable upfront fee in the amount of $11,000,000 within [...***...] of the Effective Date in accordance with the payment provisions of Section 6.10.

 

6.2                               Option Exercise Fee.  In connection with its exercise of the Option, Amgen shall pay to Xencor a non-refundable, non-creditable Option exercise fee of $50,000,000, which shall be payable as follows:

 

(a)                                 [...***...] (the “Initial Option Exercise Fee”) together with the Option Exercise Notice.  For clarity, Amgen’s exercise of the Option shall not become effective unless and until the Initial Option Exercise Fee is paid; and

 

(b)                                 [...***...] (the “Second Option Exercise Fee”) before the later of (1) that date which is [...***...] after the Option Exercise Date, and (2) [...***...] beginning after the Option Exercise Date.

 

6.3                               Development Co-Funding.  If Amgen exercises the Option, then, unless Xencor notifies Amgen within [...***...] after receipt of the Post-Exercise Development Plan and Post-Exercise Development Budget pursuant to Section 3.8(a) that Xencor elects not to share Development Costs under the Post-Exercise Development Plan (in which case Xencor shall have no obligation to reimburse any Development Costs under this Section 6.3), Xencor shall be responsible for the applicable Xencor Sharing Percentage of Shared Development Costs as set forth in this Section 6.3 (“Co-Funding Arrangement”).  It is understood that the initial Xencor Sharing Percentage shall be elected by Xencor in accordance with Section 3.8(a) above.

 

(a)                                 No later than November [...***...] of each calendar year after the Option Exercise Date, Amgen shall provide to the DC a [...***...] Post-Exercise Development Plan

and Post-Exercise Development Budget covering the next [...***...] full calendar years, and the DC shall promptly convene to review and consider such Plan and Budget.  Once approved by the DC, and during the period from delivery of such any Plan or Budget to the DC up to such approval, such Post-Exercise Development Plan and Post-Exercise Development Budget shall be deemed the Post-Exercise Development Plan and the Post-Exercise Development Budget for the periods covered by such Plan and Budget.

 

(b)                                 Between [...***...] of each calendar year after the Option Exercise Date (the “Annual Election Period”), Xencor shall notify Amgen in writing if it elects to change the Xencor Sharing Percentage to either [...***...]%,[...***...]% or [...***...]% (the “Succeeding Year Percentage Notice”).  The percentage specified in such Succeeding Year Percentage Notice shall be deemed the Xencor Sharing Percentage for the next calendar year beginning after the date of such Succeeding Year Percentage Notice.  If Xencor does not provide such a Succeeding Year Percentage Notice during the Annual Election Period, then Xencor shall be deemed to have delivered a Succeeding Year Percentage Notice as of the end of the Annual Election Period electing to maintain the same Xencor Sharing Percentage as was then currently in effect (i.e., from Xencor’s prior year’s election).  For clarity, it is understood that the Xencor may only elect [...***...]%,[...***...]% or [...***...]% (and not any other percentage) as the Xencor Sharing Percentage.  The Post-Exercise Development Plan and the Post-Exercise Development Budget in effect for the next calendar year at the time of Xencor’s delivery (or deemed delivery) of the Succeeding Year Percentage Notice is referred to below collectively as the “Initial Plan and Budget Forecast” for such next calendar year.

 

(c)                                  If Amgen proposes to update the Post-Exercise Development Plan and/or the Post-Exercise Development Budget from time to time (i.e., beyond the annual updates provided in Section 6.3(a) above), it shall provide such updated Plan and Budget to the DC.  The DC shall promptly convene to consider such update, and upon approval by the DC, the updated Plan and/or Budget, respectively, shall be deemed the Post-Exercise Development Plan and Post-Exercise Development Budget, respectively.

 

(d)                                 Amgen shall calculate Development Costs under the Post-Exercise Development Plan in accordance with GAAP, consistently applied.  Within [...***...] after the end of each calendar quarter during the term of the Co-Funding Arrangement, Amgen shall provide to Xencor a statement reflecting the total Development Costs incurred by Amgen during such calendar quarter, and the corresponding Shared Development Costs, which statement shall include a reasonably detailed breakdown of the components of such Development Costs and the Post-Exercise Development Plan activities to which such Development Costs are attributable. Together with the statement for the calendar quarter ending December 31 of each calendar year, Amgen shall provide an invoice for the then-applicable Xencor Sharing Percentage of the Shared Development Costs for such calendar year, subject to Section 6.3(b) above, and Xencor shall pay Amgen the invoiced amount within [...***...] from receipt of the invoice as provided in Section 6.10.

 

(e)                                  Xencor may terminate the Co-Funding Arrangement by so notifying Amgen between [...***...] of any calendar year, in which case the Co-Funding Arrangement shall terminate effective as of [...***...] of the next

succeeding calendar year.  Upon any termination by Xencor of the Co-Funding Arrangement under this Section 6.3(e) or Section 3.8(a), Xencor will not have any right thereafter to reinstate the Co-Funding Arrangement.  If Xencor terminates the Co-Funding Arrangement, the royalties payable to Xencor with respect to Annual Net Sales of Products shall be adjusted as specified in Section 6.7(a).

 

6.4                               Pre-POC Development Milestone Payments.  Upon the first achievement of each of the events set forth below (each, a “Pre-POC Milestone”) by Xencor, Amgen or their Affiliates, or (in the case of Amgen) a Sublicensee, the milestone payment corresponding to such Pre-POC Milestone shall be payable as follows: (a) if the applicable Pre-POC Milestone occurs on or before the earlier of (i) the Option Exercise Date, or (ii) Amgen’s exercise of the Completion Right, Xencor shall notify Amgen in writing of the occurrence of such Pre-POC Milestone Event and deliver a written invoice to Amgen for the corresponding milestone payment amount, and Amgen shall pay such invoice within [...***...]; and (b) if the applicable Pre-POC Milestone occurs after the earlier of (i) the Option Exercise Date, or (ii) Amgen’s exercise of the Completion Right, Amgen shall notify Xencor in writing of the occurrence of such Pre-POC Milestone Event and pay the corresponding milestone payment amount to Xencor within [...***...] after such occurrence:

6.6                               Certain Terms Regarding Milestone Payments.  Each Milestone shall be paid only once, regardless of whether the Milestone is achieved again with respect to additional Products or indications.  In addition, each Pre-POC Milestone shall be payable regardless of whether it is achieved by Xencor, Amgen, or any of their respective Affiliates, or, in the case of Amgen, Sublicensees, and each Post-POC Milestone shall be payable regardless of whether it is achieved by Amgen or any of its Affiliates or Sublicensees, subject to Section 3.2(c).

 

6.7                               Royalty Payments.

 

(a)                                 Royalty Rates.  Subject to the terms and conditions of this Agreement (including Section 6.8), in further consideration of the rights granted to Amgen under this Agreement, Amgen shall pay to Xencor royalties on worldwide, Annual Net Sales of each Product by Amgen, its Affiliates and Sublicensees:

 

(i)                                     Subject to Section 6.7(c) below, at the rates set out in Table A below if the Co-Funding Arrangement pursuant to Section 6.3 is in effect; and

 

(ii)                                  at the rates set out in Table B below if the Co-Funding Arrangement has been terminated.

 

Notwithstanding the foregoing, in the event the Co-Funding Arrangement is in effect during the performance of a portion of the Post-Exercise Development Plan but is subsequently terminated, Amgen shall pay to Xencor royalties on Net Sales of Products (x) at the rates set out in Table A below (as adjusted pursuant to Section 6.7(c)) until such time as the difference between the cumulative royalties paid under this Section 6.7 for all Products and the cumulative royalties for Net Sales of such Products that would have been payable under Table B below equals the aggregate amount paid by Xencor to Amgen for Development Costs pursuant to the Co-Funding Arrangement under Section 6.3, and (y) at the rates set out in Table B following the period described in (x).

(b)                                 Royalty Floors.  Notwithstanding Section 6.7(a):

 

(i)                                     In any calendar year in which Table A is applicable for the full calendar year and total aggregate Annual Net Sales of a Product exceed $[...***...], if the total amount payable pursuant to Section 6.7(a) for such calendar year is less than (A) [...***...]%, if the Xencor Sharing Percentage is [...***...]% for such calendar year and Xencor has reimbursed [...***...]% of total Shared Development Costs for all prior periods, or (B) [...***...]% in all other cases, of the Annual Net Sales of such Product in such calendar year (such percentage, in each case, the “Table A Floor Percentage”), then Amgen shall pay Xencor an additional amount (payable together with the last payment of royalties paid pursuant to Section 6.7(a) for such calendar year) such that total royalties payable for such Product for such calendar year equals the Table A Floor Percentage of the Annual Net Sales of such Product in such calendar year, unless the total royalties paid pursuant to Section 6.7(a) for such calendar year exceed the Table A Floor Percentage of the Annual Net Sales of such Product in such calendar year.  For example, if the Table A Floor Percentage for a calendar year is [...***...]% and Annual Net Sales of a Product for such calendar year are $[...***...], then royalties payable pursuant to Section 6.7(a) would be $[...***...]: (($[...***...] * [...***...]%) + ($[...***...] * [...***...]%)).  But since $[...***...] is less than $[...***...] ($[...***...] * [...***...]%), Amgen would pay Xencor an additional $[...***...] pursuant to this Section 6.7(b)(i).

 

(ii)                                  In any calendar year in which Table B is applicable and total aggregate Annual Net Sales of a Product exceed $[...***...] but do not exceed $[...***...], if the total amount payable pursuant to Section 6.7(a) for such calendar year is less than [...***...]% of the Annual Net Sales of such Product in such calendar year, then Amgen shall pay Xencor an additional amount (payable together with the last payment of royalties paid pursuant to Section 6.7(a) for such calendar year) such that total

royalties payable for such Product for such calendar year equals [...***...]% of the Annual Net Sales of such Product in such calendar year, unless the total royalties paid pursuant to Section 6.7(a) for such calendar year exceed [...***...]% of the Annual Net Sales of such Product in such calendar year.  For example, if Annual Net Sales of a Product for a calendar year are $[...***...], then royalties payable pursuant to Section 6.7(a) would be $[...***...]: (($[...***...] * [...***...]%) + ($[...***...] * [...***...]%)).  But since $[...***...] is less than $[...***...] ($[...***...] * [...***...]%), Amgen would pay Xencor an additional $[...***...] pursuant to this Section 6.7(b)(ii).

 

(iii)                               In any calendar year in which Table B is applicable and total aggregate Annual Net Sales of a Product exceed $[...***...], if the total amount payable pursuant to Section 6.7(a) for such calendar year is less than [...***...]% of the Annual Net Sales of such Product in such calendar year, then Amgen shall pay Xencor an additional amount (payable together with the last payment of royalties paid pursuant to Section 6.7(a) for such calendar year) such that total royalties payable for such Product for such calendar year equals [...***...]% of the Annual Net Sales of such Product in such calendar year, unless the total royalties paid pursuant to Section 6.7(a) for such calendar year exceed [...***...]% of the Annual Net Sales of such Product in such calendar year.  For example, if Annual Net Sales of a Product for a calendar year are $[...***...], then royalties payable pursuant to Section 6.7(a) would be $[...***...] (($[...***...] * [...***...]%) + ($[...***...] * [...***...]%) + ($[...***...] * [...***...]%) + ($[...***...] * [...***...]%)).  But since $[...***...] is less than $[...***...] ($[...***...] * [...***...]%), Amgen would pay Xencor an additional $[...***...] pursuant to this Section 6.7(b)(iii).

 

(c)                                  Adjusted Royalty Rates.  In the event that Xencor elects a Xencor Sharing Percentage of less than [...***...]% for any period pursuant to Section 3.8(a) or 6.3, and/or (without prejudice to other remedies Amgen may have), Xencor does not reimburse [...***...]% of Shared Development Costs for any period when due pursuant to Section 6.3(d), then the royalty rates in Table A and Section 6.7(f) below shall be reduced in accordance with the specific methodology set forth on Schedule K.

 

(d)                                 Reports and Royalty Payment.  Royalties shall be calculated and reported for each calendar quarter and shall be paid within [...***...] after the end of each calendar quarter.  Each payment shall be accompanied by a report of Net Sales of Products by Amgen, its Affiliates and Sublicensees in sufficient detail to permit confirmation of the accuracy of the royalty payment made, including, without limitation and on a country-by-country basis (or, where the Amgen Finance Department does not track information relating to the calculation of Net Sales on a country-by-country basis, on a region-by-region basis): (i) Net Sales, applicable royalty rates, and the amount of royalties payable hereunder; and (ii) such information as the Amgen Finance Department tracks for the purpose of calculating Net Sales, applicable royalty rates, and the royalties payable hereunder, including (to the extent so tracked) gross sales, applicable royalty adjustments, the amount of any applicable credits taken against royalties, the royalties payable, the method used to calculate the royalties payable, and the exchange rates used.

(e)                                  Royalty Term.  Amgen shall pay to Xencor royalties as set forth in this Section 6.7, on a Product-by-Product and country-by-country basis, during the Royalty Term for each Product in each country.  The “Royalty Term” means, with respect to a Product in a country, the period beginning on the First Commercial Sale of such Product in such country, and expiring on the later of:

 

(i)                                     expiration of the last-to-expire Valid Claim covering the manufacture, use, sale, offer for sale or import of such Product in such country; or

 

(ii)                                  10 years from the date of the First Commercial Sale of such Product in such country.

 

(f)                                   Effect of Expiration of Royalty Term.  On a Product-by-Product and country-by-country basis, upon expiration of the Royalty Term with respect to each Product in each country of the Territory, Amgen’s License with respect to such Product in such country shall continue in full force and effect but become perpetual and, except as set forth below in this Section 6.7(f), fully paid-up and royalty-free.  Notwithstanding the foregoing, if Xencor co-funded Development Costs pursuant to Section 6.3 and the Co-Funding Arrangement was not earlier terminated under Section 3.8(a), 6.3 or 9.6, then Amgen shall continue to pay royalties to Xencor with respect to Net Sales of each Product in each country after expiration of the Royalty Term for such Product in such country, for so long as Amgen or any of its Affiliates or Sublicensees is selling such Product in such country, at the rate of [...***...]% of such Net Sales, as adjusted pursuant to Section 6.7(c) (if applicable).  In no event shall a royalty be payable under this Section 6.7(f) with respect to Net Sales for which a royalty is due under Section 6.7(a) above.

 

6.8                               Certain Reductions to Royalties.

 

(a)                                 Third Party Royalties.

 

(i)                                     In the event that Amgen, its Affiliates or Sublicensee obtains a license under Patents of a Third Party in any country that Amgen or its Affiliate, on the advice of patent counsel, determines, in the absence of a license thereunder could be considered to be infringed by the manufacture, use, sale, offer for sale or import of the Compound contained in a Product sold by Amgen (or its Affiliate or Sublicensee) in such country (in each case, a “Necessary Third Party License”), then Amgen may deduct [...***...]% of the royalties actually paid to such Third Party under such Necessary Third Party License with respect to sales of such Product in such country from the royalty payments owed to Xencor pursuant to Section 6.7 with respect to Net Sales of such Product in such country, provided that the royalties payable to Xencor with respect to such Product in such country may not be reduced by more than [...***...]% in any calendar quarter as a result of any and all such offsets in the aggregate.

 

(ii)                                  In the event that Amgen, its Affiliates or Sublicensee obtains a license (other than a Necessary Third Party License) under Patents of a Third Party in any country that Amgen or its Affiliate determines are necessary or reasonably useful to Develop, make, use, sell, offer for sale or import a Compound or Product sold by Amgen (or its Affiliate or Sublicensee) in such country (in each case, a “Useful Third Party License”), then Amgen may deduct [...***...]% of the [...***...] actually paid to such Third Party under such Useful Third Party License with respect to sales of such Product in

(iii)                               For the avoidance of doubt, subject to the foregoing, it is understood that a Party shall be solely responsible for payment of any and all royalties and other amounts owed by such Party under its license or other agreements with Third Parties that were entered into prior to the Effective Date; provided, however, that Amgen shall be responsible for payment of all payments that become due after the Option Exercise Date under the Catalent Agreement (defined in Section 10.2(b)) as a result of the Development, manufacture, use, sale, offer for sale or import of any Product by or on behalf of Amgen or any of its Affiliates or Sublicensees.

 

(b)                                 No Valid Claim of Xencor Patent or Joint Patent.  On a country-by-country and Product-by-Product basis, for any portion of the Royalty Term with respect to a Product in a country during which no Valid Claim(s) of Xencor Patents and Joint Patents cover the (i) the manufacture, sale, offer for sale and import of such Product in such country, and (ii) the use of such Product for any approved use(s) in such country, other than Valid Claims that are contained in Amgen Patents, the royalties payable pursuant to Section 6.7 with respect to sales of such Product in such country shall be reduced by [...***...]%.

(e)                                  Absolute Floor.  In no event shall the cumulative amount of all reductions applicable to any Product in any country pursuant to this Section 6.8 reduce the royalties that would otherwise payable with respect to such Product in such country pursuant to Section 6.7 by more than [...***...]% in any quarter.

 

6.9                               Prepayment.  Amgen shall have the right to prepay any amounts payable pursuant to this Agreement without penalty, regardless of whether the event that would otherwise trigger such payment has occurred or whether Amgen has received an invoice for such payment.

6.11                        Currency Conversion.  With respect to sales of the Product invoiced and Development Costs paid in United States dollars, the amounts due hereunder (and the amounts upon which such payments are based) will be expressed in United States dollars.  With respect to sales of the Product invoiced and Development Costs paid in a currency other than United States dollars, the amounts due hereunder (and the amounts upon which such payments are based) will be reported in United States dollars, calculated using the applicable exchange rate for such currency used throughout Amgen’s group reporting system and published accounts for the applicable quarter.

 

6.12                        Taxes Generally; Withholding Taxes.

 

(a)                                 All excises, taxes, and duties, with the exception of value added taxes (“VAT”), (collectively “Taxes”) levied on account of a payment made by one Party to the other Party pursuant to this Agreement will be the responsibility of and paid by the Party receiving the payment or shall be subject to the withholding of this Section 6.12, as provided herein.

 

(b)                                 If Taxes are required under Applicable Law to be withheld by the Party making a payment from any payment hereunder, such Party will (i) deduct those Taxes from the payment and (ii) pay the Taxes to the proper taxing authority.  In the event such taxing authorities routinely provide a Tax receipt upon payment, such Party will procure a receipt for any such withholding evidencing payment of such Taxes, which will be forwarded to the Party receiving the payment.  Each Party represents and warrants that it is resident for tax purposes in the United States and agrees to provide upon request a properly completed Form W-9 or other tax form necessary to certify United States residency or claim a reduction of, or exemption from, withholding.

 

(c)                                  All payments due one Party from the other Party pursuant to this Agreement shall be paid exclusive of any VAT (which, if applicable, shall be payable upon receipt of a valid VAT invoice).

 

6.13                        Records; Inspection.  Amgen shall keep (and shall cause its Affiliates and require its Sublicensees to keep) complete, true and accurate books of accounts and records pertaining to the sale or other disposition of Products (including the number of Products sold, the gross sales and Net Sales of such Products, the royalties payable, the method used to calculate the royalties payable, and the exchange rates used) and of Development Costs incurred pursuant to Section 3.2(c) or 6.3, each in sufficient detail to permit verification of the amount of (a) royalty and sales milestone payments due by Amgen to Xencor, (b) if applicable, Development Costs for Incomplete Pre-POC Activities deductible by Amgen from Milestone payments hereunder, and (c) if applicable, Development Costs for the Post-Exercise Development Plan subject to sharing under the Co-Funding Arrangement.  Such books and records shall be kept for at least [...***...] following the end of the calendar year to which they pertain and shall be open for inspection and audit by Xencor during such [...***...] period on the terms of this Section 6.13.  Upon not less than [...***...] prior written notice, Amgen shall permit an independent, certified public accountant selected by Xencor and reasonably acceptable to Amgen, which acceptance will not be unreasonably withheld (for the purposes of this Section 6.13, the “Auditor”), to audit or inspect such books and records, for the sole purpose of whether there has been any under- or over-payment or

under- or over-statement of any such amount.  The Auditor will disclose to Xencor only such information as is reasonably necessary for Xencor to determine its rights and obligations under this Article 6.  The Auditor will send a copy of the report to Amgen at the same time it is sent to Xencor.  The report sent to both Parties will include the methodology and calculations used to determine the results.  Such inspections may be made no more than once each calendar year and during normal business hours.  Such records for any particular calendar year shall be subject to no more than one inspection.  The Auditor shall be obligated to execute a reasonable confidentiality agreement prior to commencing any such inspection.  Inspections conducted under this Section 6.13 shall be at the expense of Xencor, unless a variation or error producing an underpayment in amounts payable exceeding [...***...]% of the amount paid for a period covered by the inspection is established, in which case the reasonable out-of-pocket costs to conduct the inspection for such period and any unpaid amounts that are discovered shall be paid by Amgen, together with interest on such unpaid amounts at the rate set forth in Section 6.10 above.  Xencor and the Auditor shall conduct any such inspection in a manner that minimizes disruption of Amgen’s normal business activities.  Amgen shall use commercially reasonable efforts to obtain for Xencor the right to audit Sublicensees pursuant to the terms of this Section 6.13 and shall, at a minimum, obtain for itself reasonable and customary rights to audit Sublicensees for such purposes.  If Amgen is unable to obtain the right for Xencor to audit a Sublicensee, then Amgen shall exercise its right to audit such Sublicensee at the request and expense of Xencor (subject to reimbursement by Amgen as set forth above) and provide a copy of its auditor’s report to Xencor at the same time it is sent to Amgen.

Upon Amgen’s request following the Option Exercise Date, Xencor shall take all necessary actions to transition and transfer control to Amgen of any ongoing infringement proceedings or actions against an Infringement of the Xencor Compound-Specific Patents or Joint Patents then ongoing, and shall promptly provide all information reasonably requested by Amgen with regard to such proceedings or actions.  If Amgen fails to bring any such action or proceeding with respect to an Infringement by the sooner of (a) [...***...] following a request by Xencor to do so or (b) five days before the time limit, if any, set forth in the appropriate laws and regulations for the filing of such actions, whichever comes first, then Xencor shall have the right, with Amgen’s consent, to bring and control any such action at its own expense and by counsel of its own choice, and Amgen shall have the right, at its own expense, to be represented in any such action by counsel of its own choice.  It is understood that Amgen may exercise its rights under this Section 8.4(b)(ii) through a Sublicensee or other designee, and actions of such a Sublicensee or designee under authority from Amgen shall be deemed actions of Amgen for purposes of this Section 8.4(b)(ii).  For the avoidance of doubt, Amgen shall have the first right to initiate and control any infringement proceedings or take other appropriate actions against an Infringement of any Xencor Compound-Specific Patent that claims priority to a Xencor Patent listed in Schedule P, as described above in this Section 8.4(b)(ii).  Notwithstanding the foregoing, to the

extent a Xencor Compound-Specific Patent claims priority to a Xencor Background Patent other than those listed in Schedule P, then Amgen’s right to initiate an action to enforce such Xencor Compound-Specific Patent shall be subject to Xencor’s prior written consent.

 

(c)                                  Enforcement of Xencor CD19 Patents.

 

(i)                                     During Collaboration Period.  During the Collaboration Period, Xencor shall have the sole right, but not the obligation, to initiate infringement proceedings or take other appropriate actions against an Infringement of Xencor CD19 Patents in the Territory with respect to an Infringement.

 

(ii)                                  Following Option Exercise Date.  Following the Option Exercise Date and thereafter during the Term, Xencor shall have the first right, but not the obligation, to initiate and control any infringement proceedings or take other appropriate actions against an Infringement of the Xencor CD19 Patents in the Territory, at its own expense and by counsel of its own choice.  If Xencor fails to bring any such action or proceeding with respect to an Infringement by the sooner of (a) [...***...] following a request by Xencor to do so or (b) five days before the time limit, if any, set forth in the appropriate laws and regulations for the filing of such actions, whichever comes first, then Amgen shall have the right to bring and control any such action at its own expense and by counsel of its own choice, and Xencor shall have the right, at its own expense, to be represented in any such action by counsel of its own choice.  For the avoidance of doubt, Amgen shall have the first right to initiate and control any infringement proceedings or take other appropriate actions against an Infringement of any Xencor CD19 Patent that claims priority to a Xencor Patent listed in Schedule P, as described above in this Section 8.4(c)(ii).  Notwithstanding the foregoing, to the extent a Xencor CD19 Patent claims priority to a Xencor Background Patent other than those listed in Schedule P, then Amgen’s right to initiate an action to enforce such Xencor CD19 Patent shall be subject to Xencor’s prior written consent.

 

(d)                                 Enforcement of Xencor Background Patents.  Amgen shall have no right to initiate any infringement proceedings to enforce any Xencor Background Patent with respect to an Infringement in the Territory.

 

(e)                                  Enforcement of Amgen Patents.  Subject to Section 8.4(f), Amgen shall have the sole right to initiate any infringement proceedings or take other appropriate actions against an Infringement of any Amgen Patent in the Territory.

 

(f)                                   Allocation of Recoveries.  Except as otherwise agreed to by the Parties as part of a cost-sharing arrangement, any recovery realized as a result of litigation pursuant to this Section 8.4, after reimbursement of any litigation expenses of Xencor and Amgen, shall be retained by the Party that brought and controlled such litigation for purposes of this Agreement, except that (i) any recovery realized by Amgen as a result of such litigation, after reimbursement of the Parties’ litigation expenses, shall be treated as Net Sales of Products for purposes of royalty calculations in the period in which payment of such recovery was received; and (ii) any recovery realized by Xencor as a result of such litigation, after reimbursement of the Parties’ litigation expenses, shall be

treated as Net Sales, mutatis mutandis, of Products by Xencor, and Xencor shall pay royalties to Amgen with respect thereto at the applicable rates set forth in Section 6.7 (subject to Section 6.8(b) or 6.8(c), if applicable), mutatis mutandis, in the period in which payment of such recovery was received.  Notwithstanding the foregoing, to the extent any such recoveries are obtained with respect to Amgen Patents, the amount payable to Xencor with respect to that portion of such recovery attributable to an Amgen Patent (after reimbursement of litigation expenses) shall be reduced by [...***...]%.

 

(g)                                  Valid Claims.  In the event that, after Option Exercise Date, Amgen requests that Xencor bring (or permit Amgen to bring) an enforcement action in any jurisdiction with respect to a Xencor Patent and Xencor refuses to do so, then the claims of such patent will no longer be considered “Valid Claims” hereunder in such jurisdiction.

 

(h)                                 Cooperation.  In the event a Party brings an infringement action in accordance with this Section 8.4, the other Party shall cooperate fully, including, if required to bring such action, the furnishing of a power of attorney or being named as a party. The Parties shall keep one another informed of the status of their respective activities regarding any litigation undertaken with respect to a Xencor Patent or a Joint Patent pursuant to this Section 8.4 or settlement thereof, and the Parties shall assist one another and cooperate in any such action at the other’s reasonable request.  Without limiting the foregoing, upon request by Amgen, Xencor shall join as a party plaintiff (including if required by Applicable Law, as the sole party plaintiff) in any action initiated by Amgen or its designee with respect to an Infringement; provided that Amgen reimburses the reasonable out-of-pocket expenses incurred by Xencor in fulfilling Amgen’s request in connection with participating in such action as a party plaintiff (it being understood that Amgen shall have the right to maintain control of such action).  Neither Party shall have the right to settle any patent infringement litigation under this Section 8.4 in a manner that admits the invalidity or unenforceability of the other Party’s Patents or imposes on the other Party restrictions or obligations, without the prior written consent of the other Party, which shall not be unreasonably withheld.

 

8.5                               Patent Extensions.  Following the Option Exercise Date and thereafter during the Term, the Parties shall cooperate in obtaining patent term restorations, supplemental protection certificates and/or their equivalents, and other forms of patent term extensions for Products with respect to the Xencor Compound-Specific Patents in any country and/or region where applicable; provided that, notwithstanding Section 8.2 above, Amgen shall have the final decision making authority with respect thereto.  Amgen shall not have the right to seek any such restoration, supplemental protection certificate or other extension of any Xencor CD19 Patent or Xencor Background Patent without Xencor’s prior written consent, which Xencor may withhold in its sole discretion.  Xencor shall not, without Amgen’s prior written consent, seek any such restoration, supplemental protection certificate or other extension of (i) a Xencor Compound-Specific Patent, with respect to any product (i.e., whether or not a “Product” hereunder), or (ii) any Xencor CD19 Patent or Xencor Background Patent, with respect to a Compound or a Product.

 

8.6                               Trademarks.  As between the Parties, Amgen shall own all right, title and interest in and to any trademarks adopted by Amgen for use with the Products within the

Territory, and shall be responsible for the registration, filing, maintenance and enforcement thereof.  Xencor shall not at any time do or authorize to be done any act or thing which is likely to materially impair the rights of Amgen therein, and shall not at any time claim any right of interest in or to such marks or the registrations or applications therefor.

 

9.                                      TERM AND TERMINATION

 

9.1                               Term.  The term of this Agreement (the “Term”) shall commence on the Effective Date, and unless terminated earlier as provided in this Article 9, shall continue in full force and effect until expiration of the last-to-expire Royalty Term for any Product in the Territory.

 

9.2                               Termination If Option Not Exercised During Option Period.  This Agreement shall immediately and automatically terminate in its entirety upon expiration or termination of the Option Period in the event Amgen has not exercised the Option prior to such expiration or termination (including as described in Schedule M), subject to Section 5.3 and to Sections 9.7, 9.8, 9.9 and 9.11 below.  Notwithstanding the foregoing, in the event of a dispute as to whether all Core Collaboration Period Development Activities or the Option Data Package have been completed or delivered, this Agreement shall not terminate under this Section 9.2, and the Option Period shall be tolled until such dispute has been resolved in accordance with Article 12.

 

9.3                               Termination by Amgen For Convenience.  Amgen shall have the right to terminate this Agreement for convenience upon 90 days prior written notice to Xencor.

 

9.4                               Termination for Breach.  Either Party to this Agreement may terminate this Agreement in the event the other Party shall have materially breached or defaulted in the performance of any of its material obligations hereunder, and such default shall have continued for 90 days (or, in the case of breach of undisputed payment obligations, 30 days) after written notice thereof was provided to the breaching Party by the non-breaching Party.  Any such termination shall become effective at the end of such 90-day (or 30-day, as applicable) period unless the breaching Party has cured any such breach or default prior to the expiration of such period (or, except in the case of breach or default of payment obligations, if such breach or default cannot reasonably be cured within such 90-day period, unless, prior to the expiration of the 90-day period, the breaching Party has undertaken appropriate steps to commence such cure during such 90-day period and diligently continues to pursue reasonable efforts to cure such breach in a manner reasonably assuring such cure within a reasonable period of time thereafter).  Any right to terminate under this Section 9.4 shall be stayed and the cure period tolled in the event that, during any cure period, the Party alleged to have been in material breach or default shall have initiated dispute resolution in accordance with Article 12 with respect to the alleged breach, which stay and tolling shall continue until such dispute has been resolved in accordance with Article 12.  In addition, Xencor shall have: (a) the right to terminate this Agreement immediately upon written notice to Amgen, if Amgen or its Affiliate initiates a Xencor Patent Challenge; and (b) the right to terminate any sublicense under the License granted to a Sublicensee, if such Sublicensee or its affiliate initiates a Xencor Patent Challenge, provided that, in each of (a) and (b) above Xencor shall not have such termination right if the Xencor Patent Challenge is withdrawn or dismissed within 30 days after a request by Xencor to do so.  For such purposes, a “Xencor Patent Challenge” means the commencement or assertion by Amgen, its Affiliate or Sublicensee (i) in any lawsuit or reexamination proceeding (excluding any administrative opposition proceeding), of any claim challenging the

 

45











 

validity or enforceability of an issued Xencor Patent to the extent such Patent and such challenge apply to a Compound, or (ii) in any administrative opposition proceeding, of any claim challenging the validity or enforceability of a Xencor Patent; provided, however, that none of the following shall constitute a “Xencor Patent Challenge” for purposes of this Section 9.4: (A) Amgen’s or its Affiliate’s good faith assertion that (x) any Invention claimed by a Patent filed by or on behalf of Xencor as a Xencor Patent was an Amgen Invention or Joint Invention, or (y) any Invention claimed by a Joint Patent filed by or on behalf of Xencor as a Joint Patent was a Joint Invention; (B) Amgen’s or its Affiliate’s good faith assertion, in the context of whether a payment of royalties is due to Xencor, that no Valid Claim within the Xencor Patents applies with respect to a Product; (C) any claim made by Amgen or its Affiliate as a defense in any lawsuit or administrative proceeding brought by Xencor; and (D) any lawsuit, reexamination proceeding or opposition brought by Amgen or its Affiliate challenging the validity or enforceability of any claim within an issued Xencor Patent which claim does not Claim the composition of matter or formulation of, or any method of making or using, a Compound (and not challenging the validity or enforceability of any claim within an issued Xencor Patent that Claims the composition of matter or formulation of, or any method of making or using, a Compound).

 

9.5                               Termination for Bankruptcy.  Either Party may terminate this Agreement upon written notice to the other Party in the event any of the following occurs with respect to such other Party: (i) the other Party becomes bankrupt, or files a petition in bankruptcy or makes a general assignment for the benefit of creditors or otherwise acknowledges in writing insolvency, or is adjudged bankrupt, and such Party (A) fails to assume this Agreement in any such bankruptcy proceeding within 30 days after filing or (B) assumes and assigns this Agreement to a Third Party; (ii) the other Party is placed in a process of complete liquidation; (iii) a trustee or receiver is appointed for any substantial portion of the other Party’s business and such trustee or receiver is not discharged within 60 days after appointment; (iv) any case or proceeding shall have been commenced or other action taken against the other Party in bankruptcy or seeking liquidation, reorganization, dissolution, a winding-up arrangement, composition or readjustment of its debts or any other relief under any bankruptcy, insolvency, reorganization or similar act or law of any jurisdiction now or hereafter in effect and is not dismissed or converted into a voluntary proceeding governed by clause (i) above within 60 days after filing; or (v) 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 such event shall have continued for a period of 60 days and none of the following has occurred: (1) it is dismissed, (2) it is bonded in a manner reasonably satisfactory to the Party with the termination right under this Section 9.5, or (3) it is discharged.

 

9.6                               Alternative to Amgen Termination for Xencor Breach.  In the event that Amgen is entitled to terminate this Agreement for Xencor’s material breach (after notice, opportunity to cure, and any dispute resolution proceedings, all as set forth in Section 9.4), but Amgen wishes to retain the License, Option and other rights granted to it hereunder, Amgen may, in lieu of terminating this Agreement, terminate Article 0, and/or (ii) if Amgen has not yet exercised the Option, Amgen shall have the right to exercise the Completion Option as described in Section 3.3; provided, however, that, except for any such terminated provisions, this Agreement, including the License and, if not previously exercised, the Option, will remain in full force and effect in accordance with its terms, subject to Amgen’s continued compliance with its obligations hereunder.  Notwithstanding the foregoing, if the Xencor breach that entitled Amgen to terminate

 

46











 

this Agreement was a breach of Section 6.3, then upon exercise of its rights under this Section 9.6, Amgen shall also have the right to terminate Section 6.3.

 

9.7                               Consequences of Termination.

 

(a)                                 Upon any termination of this Agreement by either Party as permitted by this Article 9, all rights and obligations of the Parties hereunder (including the License granted by Xencor to Amgen hereunder) shall terminate and be of no further force or effect, except as otherwise expressly set forth below in this Section 9.7 and in Sections 9.8, 9.9 and 9.11.

 

(b)                                 Solely in the case of termination of this Agreement pursuant to Section 9.2, Section 5.3 shall survive.

 

(c)                                  Solely in the case of termination of this Agreement pursuant to Section 9.2 or 9.3, or termination of this Agreement by Xencor pursuant to Section 9.4, the following shall apply:

 

(i)                                     Effective upon any such termination, Amgen shall, and it hereby does, grant to Xencor an exclusive, perpetual, royalty-free license, with the right to sublicense through multiple tiers, under Amgen and Joint Compound-Specific Patents, to Develop, make, have made, use, sell, have sold, offer for sale and import Reverted Products.  For such purposes: “Amgen and Joint Compound-Specific Patents” means all Amgen Patents and Joint Patents that, in each case, (A) Claim only Option Period Invention(s) and/or the composition of matter or formulation of, or any method of making or using, a Compound, alone or as incorporated into a Product, or a Product (excluding any active ingredient that is not a Compound), and (B) do not Claim the composition of matter or formulation of, or any method of making or using, any Antibody that is not a Compound or any product that is not a Product.

 

For purposes of the foregoing, “Reverted Product” means any Product containing any of the following:

 

a.                                      XmAb5871;

 

b.                                      any Compound that comprises any of the Fc variants listed in Schedule A attached hereto (as “variant” is defined in such Schedule);

 

c.                                       any Compound that comprises any other Fc variant owned by, or licensed to, Xencor during the Option Period, provided that Xencor notifies Amgen in writing of the identity of such Fc variant within 90 days after the earlier of (A) the Option Exercise Date or (B) the termination of this Agreement, which written notice shall expressly refer to this Section 9.7(c)(i)c; or

 

d.                                      any Compound for which (A) Amgen or Xencor conducted any clinical trial prior to termination of this Agreement or (B) Xencor conducts any clinical trial within 3 years after such termination.

 

For clarity, Amgen retains the right at all times after termination of this Agreement pursuant to Section 9.2 or 9.3, or termination of this

 

47











 

Agreement by Xencor pursuant to Section 9.4, to practice the Amgen and Joint Compound-Specific Patents and Amgen Know-How for all purposes, except, from the date of such termination, to Develop, make, have made, use, sell, have sold, offer for sale or import Reverted Products;

 

(ii)                                  Effective upon any such termination, Amgen shall, and it hereby does, grant to Xencor a non-exclusive, perpetual, royalty-free license, with the right to sublicense, under Amgen Blocking Patents, solely to Develop, make, have made, use, sell, offer for sale, have sold and import Reverted Products in the Field in the Territory.  “Amgen Blocking Patents” means Amgen Patents, other than Amgen Patents within Amgen and Joint Compound-Specific Patents, that Claim inventions actually practiced or generated by or on behalf of Amgen in the Development, manufacture, use, sale, offer for sale or import of Compound or Products in the Field in the Territory prior to termination of this Agreement;

 

(iii)                               As promptly as practicable (and in any event within 90 days) after such termination, Amgen shall (A) deliver to Xencor all then—existing Regulatory Documents and Data Controlled by Amgen to the extent they pertain to Compound and Products (or true, correct and complete copies thereof), and hereby grants to Xencor, effective as of the effective date of such termination, the right to use and reference all such Regulatory Documents and Data as necessary or useful for the exercise of the licenses granted to Xencor under Section 9.7(c)(i) or (ii) as applicable, (B) disclose to Xencor all Amgen Know-How necessary or useful for the practice of the licenses granted pursuant to Section 9.7(c)(i) or (ii), to the extent such Amgen Know-How was actually used or generated by Amgen in the course of manufacturing, Developing or commercializing a Reverted Product, and hereby grants to Xencor, effective as of the effective date of such termination, the right to use and practice such Amgen Know-How as necessary or useful for the exercise of the license granted to Xencor under Section 9.7(c)(i) or (ii), (C) transfer and assign to Xencor all of its right, title and interest in and to all then-existing Regulatory Filings with respect to the Reverted Products, and (D) cooperate reasonably in transitioning the Reverted Products to Xencor;

 

(iv)                              To the extent that any of the foregoing licenses or rights granted by Amgen include Patents or Know-How that were acquired from a Third Party, but that are subject to payment or other obligations to a Third Party, then Amgen shall so notify Xencor, together with a true, complete and correct written description of such payment and/or other obligations (a “Third Party Technology Notice”), and the inclusion of such Third Party technology in such licenses shall be subject to Xencor’s agreeing in writing to reimburse, and promptly reimbursing, Amgen for any payments that become owing to such Third Party by reason of the grant to, or the exercise of Xencor’s rights with respect to, the Third Party technology, to the extent the same were disclosed to Xencor in the Third Party Technology Notice.  In addition, as a condition of such license, upon request, Xencor shall agree in writing to be bound by any obligations that are applicable to sublicensees of the applicable Third Party technology

 

48











 

under the agreement under which such Third Party technology was acquired;

 

(v)                                 Xencor shall have the right, but not the obligation, to purchase from Amgen at Amgen’s fully-burdened manufacturing cost (calculated in accordance with GAAP, consistently applied) any or all quantities of usable clinical and/or commercial GMP-grade Compound or Products in Amgen’s or its Affiliates’ possession as of the date of termination.  Any packaging, transport, insurance and other costs relating to delivery shall be at Xencor’s expense; and

 

(vi)                              If Amgen was manufacturing, or having manufactured on its behalf, any Reverted Product, or the Compound contained therein, prior to termination, then at Xencor’s request, until the earlier of (A) such time as Xencor has secured another source of Compound or Product that is able to meet Xencor’s Compound and Product quality and quantity requirements, and (B) 18 months after such termination, Amgen shall use Commercially Reasonable Efforts to supply, or cause to be supplied, to Xencor such quantities of Compound or Product as Xencor may reasonably require for the Development and commercialization of Compound and Products in the Field in the Territory; provided that Xencor shall use commercially reasonable efforts to secure another source of supply of such Compound and Product as soon as reasonably practicable.

 

(vii)                           Notwithstanding the foregoing, in no event shall Xencor as a result of this Section 9.7(c) have any right or license with respect to any Antibody or compound that is not a “Compound” as defined in this Agreement.

 

9.8                               Accrued Obligations.  The expiration or termination of this Agreement for any reason shall not release either Party from any liability that, at the time of such expiration or termination, has already accrued to the other Party or that is attributable to a period prior to such expiration or termination, nor will any termination of this Agreement preclude either Party from pursuing all rights and remedies it may have under this Agreement, or at law or in equity, with respect to breach of this Agreement.  Notwithstanding the foregoing, in the event that Amgen provides notice of termination under Section 9.3 or 9.4 above prior to the date the Second Option Exercise Fee is due, then such payment shall not be deemed to have accrued and Amgen shall not be obligated to make such payment.

 

9.9                               General Survival.  The following provisions of this Agreement shall survive expiration or termination of this Agreement for any reason:  Articles 1, 11, 12 and 13, and Sections 6.10 through 6.13, 7.1, 7.2, Section 8.1, Section 9.1, Sections 9.7 through 9.11, Section 10.8, Section 10.9, and the first sentence of Section 7.3.  In addition, upon the expiration, but not an earlier termination, of this Agreement, the following Sections shall also survive:  Section 6.7(f), if applicable, and the corresponding provisions of Sections 6.7(c), 6.7(d) and 6.8; and Section 8.4, with respect to Infringements occurring prior to such expiration.

 

9.10                        Bankruptcy.  All rights and licenses granted under or pursuant to this Agreement by Xencor or Amgen are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code and other similar laws in a jurisdiction outside the United States, licenses of rights to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code. The Parties agree that the Parties, as

 

49











 

licensees of such rights under this Agreement, shall retain and may fully exercise all of their rights and elections under the U.S. Bankruptcy Code or such similar laws in a jurisdiction outside the United States.  The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against either Party under the U.S. Bankruptcy Code, the Party hereto that is not a party to such proceeding shall be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property (including, in the case of Xencor as the party to such proceeding, all Xencor Know-How and all Xencor Information and Materials and Data), and same, if not already in its possession, shall be promptly delivered to them (i) upon any such commencement of a bankruptcy proceeding upon its written request therefor, unless the Party subject to such proceeding elects to continue to perform all of its obligations under this Agreement, or (ii) if not delivered under (i) above, following the rejection of this Agreement by or on behalf of the Party subject to such proceeding upon written request therefor by the non-subject Party.

 

9.11                        Additional Rights.  Neither Party will be precluded from pursuing all rights and remedies that it may have hereunder at law or in equity with respect to any breach of this Agreement nor prejudice either Party’s right to obtain performance of any obligation.

10.1                        Representations and Warranties of the Parties.  Each Party hereby represents and warrants to the other Party as of the Effective Date that it has full corporate power and authority and has taken all requisite corporate action necessary to enter into and perform this Agreement, and that this Agreement is a legal and valid obligation binding upon such Party and enforceable in accordance with its terms.  The execution, delivery and performance of this Agreement by such Party do not conflict with, or constitute a default under, any agreement, instrument or understanding, oral or written, to which such Party is a party or by which it is bound, nor, to its knowledge as of the Effective Date, violate any Applicable Law.

 

10.2                        Representations and Warranties of Xencor.  Xencor represents and warrants to Amgen as of the Effective Date that:

Neither Xencor nor, to Xencor’s knowledge, [...***...] or Catalent, is in breach or default under the [...***...] Agreement or Catalent Agreement, as applicable.  Xencor has provided true and complete copies of the [...***...] Agreement and the Catalent Agreement to Amgen;

(e)                                  Schedules D, E and F attached hereto accurately and completely identify all Patents in which Xencor has any rights as of the Effective Date that have been used in connection with or are reasonably necessary or useful for, the Development, manufacture or commercialization of Compounds or Products, and Xencor does not have rights in or to any Patent or Information or Materials that would be within the Xencor Patents or the Xencor Know-How, but for the fact that Xencor does not Control such Patent or Information or Materials.  XmAb5871 does not use or incorporate any Xencor XmAb Xtend Technology.  To Xencor’s knowledge as of the Effective Date, (i) the issued patents within the Xencor Patents are valid and enforceable, (ii) there are no claims against Xencor as of the Effective Date, nor any reissue, reexamination, interference, opposition or similar proceedings pending or threatened, with respect to the Xencor Patents or Xencor Know-How, and (iii) with respect to all Patents of Third Parties Xencor has disclosed to Amgen prior to the Effective Date as being relevant to the Development, manufacture, or commercialization of Compound, all information disclosed by Xencor to Amgen regarding such Patents is correct, and Xencor has not knowingly omitted to disclose to Amgen any material information in Xencor’s possession regarding such Patents;

 

(f)                                   it has conducted, and has caused its contractors to conduct, all preclinical and clinical studies for Products and manufacturing of the Compound and Products, in accordance with (i) all Applicable Laws of the United States and the country in which such clinical studies are conducted, (ii) the applicable published standards and guidelines of the FDA and the Regulatory Authority in such country, and (iii) the scientific standards applicable to the conduct of such studies and activities in the United States and in such country including current good laboratory practice, current good clinical practice and current good manufacturing practice.

(g)                                  to its knowledge, Xencor has not employed any personnel, and has not knowingly used a contractor or consultant, debarred by the FDA (or subject to a similar sanction of a Regulatory Authority), or who is subject of an FDA debarment investigation or proceeding (or similar proceeding of a Regulatory Authority);

 

(h)                                 Except as disclosed to Amgen prior to the Effective Date, there are no inquiries, actions or other proceedings pending before or, to Xencor’s knowledge, threatened by, any Regulatory Authority or other government agency with respect to the Compound or Products or any facility where the Compound or any Product is manufactured, and neither Xencor nor, to the knowledge of Xencor, its subcontractors, has received written notice threatening any such inquiry, action or other proceeding;

 

(i)                                     Xencor has made available to Amgen for its review all material Data generated by or on behalf of Xencor with respect to the Compound or Products.  To Xencor’s knowledge, all of the Data and information relating to Compound and Products that Xencor has disclosed or made available to Amgen is accurate in all material respects, and Xencor has not omitted therefrom any material Data or information relating to the Compound or Products in Xencor’s possession or control prior to the Effective Date that a reasonable person in Amgen’s position would want to have examined prior to executing this Agreement.

 

10.3                        Covenants.

 

(a)                                 Covenant by Xencor.  Following delivery of the Option Data Package, if Amgen requests that Xencor provide information known to Xencor relating to the accuracy of any representation or warranty made by Xencor in Section 10.2 as if made on the date of such request, then to the extent such information has not previously been disclosed to Amgen, Xencor shall provide such information to Amgen within 30 days after such request.

 

(b)                                 Mutual Covenants.  Each Party hereby covenants to the other Party that:

 

(i)                                     it will conduct, and will cause its contractors to conduct, all preclinical and clinical studies for Products and manufacturing of the Compound and Products, in accordance with (i) all Applicable Laws of the United States and the country in which such clinical studies are conducted, (ii) the known or published standards of the FDA and the Regulatory Agency in such country, and (iii) the scientific standards applicable to the conduct of such studies and activities in the United States and in such country including current good laboratory practice, current good clinical practice and current good manufacturing practice.  Neither such Party, nor any officer, employee or agent of such Party, will make an untrue statement of a material fact to any Regulatory Authority with respect to the Compound or Products (whether in any submission to such Regulatory Authority or otherwise), and neither will knowingly fail to disclose a material fact required to be disclosed to any Regulatory Authority with respect to the Compound or Products; and

 

52













 

(ii)                                  it will not knowingly employ any personnel or knowingly use a contractor or consultant that has been debarred by the FDA (or subject to a similar sanction of a Regulatory Authority), or that is subject of an FDA debarment investigation or proceeding (or similar proceeding of a Regulatory Authority).

 

10.4                        Diligence Obligations of Amgen.  Except as otherwise provided herein, following the Option Exercise Date, Amgen shall use Commercially Reasonable Efforts (directly and/or through one or more Affiliates and/or Sublicensees) to Develop, obtain Marketing Approval for and commercialize at least one Product.  The foregoing shall include use of Commercially Reasonable Efforts (directly and/or through one or more Affiliates and/or Sublicensees) with respect to each of the Major Markets.  Amgen shall keep Xencor reasonably informed as to its progress and activities relating to the Development, commercialization, marketing and promotion of Compound and Products in the Territory, as follows:

 

(a)                                 during the existence of the DC, via DC meetings and required reports to the DC under Article 0;

 

(b)                                 after the DC ceases to exist and prior to First Commercial Sale of the first Product, by delivering [...***...] written reports to Xencor in [...***...] summarizing the status of Amgen’s and its Affiliates’ and Sublicensees’ efforts with respect to Products, including significant Development, clinical trial progress, regulatory approval and commercialization plans, activities and results with respect to Products; and

 

(c)                                  after First Commercial Sale of the first Product, by delivering annual written reports to Xencor in January of each year summarizing the status of Amgen’s and its Affiliates’ and Sublicensees’ efforts with respect to Products, including significant Development, clinical trial progress, regulatory approval and commercialization plans, activities and results with respect to Products.

 

Without limiting the generality of the foregoing (and both during and after the DC’s existence), Amgen shall provide Xencor with written notice with respect to the following within [...***...] after occurrence: (i) filing of any IND for a Compound or Product in a Major Market; (ii) initiation of any clinical trial of a Compound or Product; (iii) filing of a BLA with respect to any Product in a Major Market; (iv) receipt of Marketing Approval for any Product in a Major Market; and (v) First Commercial Sale of a Product in a Major Market; in each case to the extent such activity is undertaken by or on behalf of Amgen or its Affiliates or Sublicensees.

 

10.5                        Exclusivity of Efforts.  For clarity, it is understood that any Antibody that Amgen Develops or commercializes and which meets the definition “Compound” under Section 1.21 above, shall be deemed a “Compound” hereunder for all purposes of this Agreement, including the milestone and royalty obligations in Sections 6.5 and 6.7, whether or not such Compound incorporates or utilizes any Xencor Patents or Xencor Know-How.  Similarly any Antibody that is Controlled by Xencor as of the Effective Date or during the Term that meets the definition of “Compound” under Section 1.21 above shall also be deemed a “Compound” for all purposes of this Agreement, including the milestone and royalty provisions of Sections 6.5 and 6.7.

 

10.6                        Change of Control of Xencor.  Xencor shall notify Amgen in writing promptly of the closing of any Change of Control of Xencor involving a Significant Pharmaceutical Company.  With respect to any such Change of Control occurring prior to the Option

 






*** Confidential Treatment Requested

 

53













 

Exercise Date, Amgen shall have the rights set forth in Section 3.3 and Schedule M.  With respect to any such Change of Control occurring after the Option Exercise Date, during the [...***...] period after Xencor provides notice of the closing of such Change of Control, Amgen may, by written notice to Xencor, terminate Article 0.  If Amgen so terminates Article 2, then any decision that would otherwise have been made by the DC shall be made by Amgen; it being understood that the limitations on a Party’s deciding vote on the DC specified in Section 2.5 shall also apply to Amgen’s right to make decisions under this Section 10.6.  For the avoidance of doubt, except as expressly set forth above in this Section 10.6, no Change of Control of either Party shall have any effect on the respective rights and obligations of the Parties under this Agreement.

 

10.7                        Review of Material Agreements.  During the Collaboration Period, prior to entering into any material agreements with respect to either the Compound or Products (including the Development or manufacture thereof), Xencor shall provide Amgen with a reasonable opportunity to review and comment on any such agreement and shall consider in good faith any comments provided thereon by Amgen.

 

10.8                        Disclaimer.  Except as expressly set forth in this Agreement, THE TECHNOLOGY AND INTELLECTUAL PROPERTY RIGHTS PROVIDED BY EACH PARTY HEREUNDER ARE PROVIDED “AS IS,” AND EACH PARTY EXPRESSLY DISCLAIMS ANY AND ALL WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, THE WARRANTIES OF DESIGN, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THE INTELLECTUAL PROPERTY RIGHTS OF THIRD PARTIES, OR ARISING FROM A COURSE OF DEALING, USAGE OR TRADE PRACTICES.

 

10.9                        Limitation of Liability.  EXCEPT FOR LIABILITY FOR BREACH OF ARTICLE 7 NEITHER PARTY SHALL BE ENTITLED TO RECOVER FROM THE OTHER PARTY ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES IN CONNECTION WITH THIS AGREEMENT OR ANY LICENSE GRANTED HEREUNDER; provided, however, that this Section 10.9 shall not be construed to limit either Party’s indemnification obligations under Article 11.

 

11.                               INDEMNIFICATION

 

11.1                        Indemnification of Xencor.  Amgen shall indemnify and hold harmless each of Xencor, its Affiliates and the directors, officers, stockholders and employees of such entities and the successors and assigns of any of the foregoing (the “Xencor Indemnitees”), from and against any and all liabilities, damages, penalties, fines, costs, expenses, including, reasonable attorneys’ fees and other expenses of litigation (“Liabilities”), from any claims, actions, suits or proceedings brought by a Third Party (a “Third Party Claim”) to which any Xencor Indemnitee may become subject, to the extent such Liabilities arise directly or indirectly out of: (a) the research, Development, manufacture, use, handling, storage, marketing, distribution, importation, sale or other disposition of any Compound or Product by or on behalf of Amgen, its Affiliates or Sublicensees; (b) the gross negligence or willful misconduct of any Amgen Indemnitee; or (c) Amgen’s breach of any representation, warranty, covenant or other agreement made by Amgen in this Agreement; except, in each case, to the extent such Liabilities result from the gross negligence or willful misconduct of any Xencor Indemnitee or the breach by Xencor of any warranty, representation, covenant or agreement made by Xencor in this Agreement.  For purposes of clarification, the foregoing shall not relieve Xencor of its co-funding obligations under Section 6.3 (if applicable).

11.2                        Indemnification of Amgen.  Xencor shall indemnify and hold harmless each of Amgen, its Affiliates and Sublicensees and the directors, officers and employees of Amgen, its Affiliates and Sublicensees and the successors and assigns of any of the foregoing (the “Amgen Indemnitees”), from and against any and all Liabilities from any Third Party Claims incurred by any Amgen Indemnitee, arising from, or occurring as a result of (a) the research, Development, manufacture, use, handling, storage, marketing, distribution, importation, sale or other disposition of any Compound or Product by or on behalf of Xencor, its Affiliates or its Third Party licensees; (b) the gross negligence or willful misconduct of any Xencor Indemnitee; or (c) Xencor’s breach of any representation, warranty, covenant or other agreement made by Xencor in this Agreement; except, in each case, to the extent such Liabilities result from the gross negligence or willful misconduct of any Amgen Indemnitee or the breach by Amgen of any warranty, representation, covenant or agreement made by Amgen in this Agreement.

 

11.3                        Procedure.  A Party that intends to claim indemnification under this Article 11 (the “Indemnitee”) shall promptly notify the other Party (the “Indemnitor”) in writing of the assertion or the commencement of a Third Party Claim and will provide the Indemnitor such information with respect thereto that the Indemnitor may reasonably request.  The Indemnitor shall be entitled to participate in the defense of any Third Party Claim and, subject to the limitations set forth in this Section, shall be entitled to control and appoint lead counsel for such defense, in each case at its expense.  If the Indemnitor shall assume the control of the defense of any Third Party Claim in accordance with the provisions of this Section 11.3, the Indemnitor shall obtain the prior written consent of the Indemnitee (not to be unreasonably withheld) before entering into any settlement of such Third Party Claim.  The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any action with respect to a Third Party Claim, to the extent prejudicial to its ability to defend such action, shall relieve such Indemnitor of any liability to the Indemnitee under this Section 11.3, but the omission to so deliver written notice to the Indemnitor shall not relieve the Indemnitor of any liability that it may have to any Indemnitee otherwise than under this Section 11.3.  The Indemnitee under this Section 11.3 shall cooperate fully with the Indemnitor and its legal representatives in the investigation of any action with respect to a Third Party Claim covered by this indemnification.

 

12.                               DISPUTE RESOLUTION

 

12.1                        Discussions.  Upon the written request of either Party to the other Party, any claim, dispute, or controversy as to the breach, enforcement, interpretation or validity of this Agreement (other than any dispute the resolution of which is within the express authority of the DC), including any action or claim based on tort, contract, or statute, or concerning the interpretation, effect, termination, validity, performance and/or breach of this Agreement (each, a “Dispute Claim”), will be referred to the Chief Executive Officer of Xencor and a designated official of Amgen (who shall be a Vice President or higher with authority to resolve such matter), for resolution.  In the event the two individuals referred to in the preceding sentence are unable to resolve such dispute within [...***...] after the initial written request, then, upon the written demand of either Party, the Dispute Claim shall be subject to arbitration, as provided in Section 12.2.

12.2                        Arbitration.

 

(a)                                 Claims.  Subject to Section 12.3 below, any Dispute Claim that is not resolved under Section 12.1 within [...***...] after a Party’s initial written request for resolution, shall be resolved by final and binding arbitration administered by JAMS (the “Administrator”) in accordance with its Comprehensive Arbitration Rules and Procedures (the “Rules”), except to the extent any such Rule conflicts with the express provisions of this Section 12.2.  (Capitalized terms used but not otherwise defined in this Agreement shall have the meanings provided in the Rules.)  The Arbitration shall be conducted by one neutral arbitrator selected in accordance with the Rules, provided that such individual shall not be a current or former employee or director, or a current stockholder, of either Party, any of their respective Affiliates or any Sublicensee.  The Arbitration shall be held in Los Angeles, California.

 

(b)                                 Discovery.  Within [...***...] after selection of the Arbitrator, the Arbitrator shall conduct the Preliminary Conference.  In addressing any of the subjects within the scope of the Preliminary Conference, the Arbitrator shall take into account both the needs of the Parties for an understanding of any legitimate issue raised in the Arbitration and the desirability of making discovery efficient and cost-effective.  In that regard, the Parties agree to the application of the E-Discovery procedures set forth in Rule 16.2(c) of JAMS’ Expedited Procedures.  In addition, each Party shall have the right to take up to [...***...] of deposition testimony, including expert deposition testimony.  The Parties agree that the Arbitrator shall set a discovery cutoff not to exceed [...***...] (rather than [...***...]) calendar days after the Preliminary Conference for percipient discovery and not to exceed [...***...] (rather than [...***...]) calendar days after the Preliminary Conference for expert discovery.  These dates may be extended by the Arbitrator for good cause shown.

 

(c)                                  Hearing; Decision.  The Hearing shall commence within [...***...] calendar days after the discovery cutoff.  The Arbitrator shall require that each Party submit concise written statements of position and shall permit the submission of rebuttal statements, subject to reasonable limitations on the length of such statements to be established by the Arbitrator.  The Hearing shall be no longer than [...***...] business days in duration.  The Arbitrator shall also permit the submission of expert reports.  The Arbitrator shall render the Award within [...***...] days after the Arbitrator declares the Hearing closed, and the Award shall include a written statement describing the essential findings and conclusions on which the Award is based, including the calculation of any damages awarded.  The Arbitrator will, in rendering his or her decision, apply the substantive law of the State of California, without giving effect to its principles of conflicts of law, and without giving effect to any rules or laws relating to arbitration.  The Arbitrator’s authority to award special, incidental, consequential or punitive damages shall be subject to the limitation set forth in Section 10.9.  The Award rendered by the Arbitrator shall be final, binding and non-appealable, and judgment may be entered upon it in any court of competent jurisdiction.  However, the Parties agree that the JAMS Optional Arbitration Appeal Procedures shall apply to the Arbitration, at the request by either Party in accordance with such Appeal Procedures. If a Party appeals the Award rendered by the Arbitrator, the Award issued by the Appeal Panel (as defined in such Appeal Procedures) shall be final,

56













 

binding and non-appealable, and judgment may be entered upon it in any court of competent jurisdiction.

 

(d)                                 Costs.  Each Party shall bear its own attorney’s fees, costs, and disbursements arising out of the Arbitration, and shall pay an equal share of the fees and costs of the Arbitrator; provided, however, the Arbitrator shall be authorized to determine whether a Party is the prevailing party, and if so, to award to that prevailing party reimbursement for any or all of its reasonable attorneys’ fees, costs and disbursements (including, for example, expert witness fees and expenses, photocopy charges, travel expenses, etc.), and/or the fees and costs of the Administrator and the Arbitrator.

 

12.3                        Court Actions.  Nothing contained in this Agreement shall deny either Party the right to seek injunctive or other equitable relief from a court of competent jurisdiction in the context of a bona fide emergency or prospective irreparable harm, and such an action may be filed and maintained notwithstanding any ongoing discussions between the Parties or any ongoing arbitration proceeding.  In addition, either Party may bring an action in any court of competent jurisdiction to resolve disputes pertaining to the validity, construction, scope, enforceability, infringement or other violations of Patents or other intellectual property rights, and no such claim shall be subject to arbitration pursuant to Section 12.2.

 

13.                               GENERAL PROVISIONS

 

13.1                        Force Majeure.  If the performance of any part of this Agreement (except for any payment obligation under this Agreement) by either Party is prevented, restricted, interfered with or delayed by an event or circumstance of force majeure (including, fire, flood, embargo, power shortage or failure, acts of war, insurrection, riot, terrorism, strike, lockout or other labor disturbance or acts of God) that is not within the reasonable control, directly or indirectly, of the Party seeking to have its performance excused thereby, the Party so affected shall, upon giving written notice to the other Party, be excused from such performance to the extent of such prevention, restriction, interference or delay; provided that the affected Party shall use its reasonable efforts to avoid or remove such causes of non-performance and shall continue performance with the utmost dispatch whenever such causes are removed.  The Parties agree that a Party’s financial inability or other inability to obtain funds sufficient to perform its obligations hereunder shall not be grounds for obtaining relief under this Section 13.1.

 

13.2                        Governing Law.  This Agreement and all questions regarding its validity or interpretation, or the breach or performance of this Agreement, shall be governed by, and construed and enforced in accordance with, the laws of the State of California, without reference to conflict of law principles.

 

13.3                        Waiver.  Except as otherwise expressly provided in this Agreement, any term of this Agreement may be waived only by a written instrument executed by a duly authorized representative of the Party waiving compliance.  The delay or failure of either Party at any time to require performance of any provision of this Agreement shall in no manner affect such Party’s rights at a later time to enforce the same.  No waiver by either Party of any condition or term in any one or more instances shall be construed as a further or continuing waiver of such condition or term or of another condition or term.

 

13.4                        Modification.  No amendment or modification of any provision of this Agreement shall be effective unless in writing signed by a duly authorized representative of each Party.

 

57













 

No provision of this Agreement shall be varied, contradicted or explained by any oral agreement, course of dealing or performance or any other matter not set forth in an agreement in writing and signed by a duly authorized representative of each Party.

 

13.5                        Severability.  In the event any provision of this Agreement should be held invalid, illegal or unenforceable in any jurisdiction, the Parties shall negotiate in good faith a valid, legal and enforceable substitute provision that most nearly reflects the original intent of the Parties and all other provisions of this Agreement shall remain in full force and effect in such jurisdiction.  Such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of such provision in any other jurisdiction.

 

13.6                        Entire Agreement.  This Agreement (including the Exhibits and Schedules attached hereto) constitutes the entire agreement between the Parties relating to its subject matter and supersedes all prior or contemporaneous agreements, understandings or representations, either written or oral, between Xencor and Amgen with respect to such subject matter.

 

13.7                        Notices.  Unless otherwise agreed by the Parties or specified in this Agreement, all communications between the Parties relating to, and all written documentation to be prepared and provided under, this Agreement shall be in the English language.

Any notice required or permitted to be given concerning this Agreement shall be effective upon receipt by the Party to whom it is addressed or within two (2) business days of dispatch whichever is earlier.

 

13.8                        Assignment.  This Agreement shall not be assignable by either Party to any Third Party hereto without the written consent of the other Party hereto; except either Party may assign this Agreement without the other Party’s consent:

 

58













 

(a)                                 to a Third Party in connection with the transfer or sale of all or substantially all of the business of such Party to which this Agreement relates, whether by merger, sale of stock, sale of assets or otherwise (a “Sale Transaction”), subject to Section 13.9; or

 

(b)                                 to an Affiliate, provided that the assigning Party shall remain liable and responsible to the non-assigning Party hereto for the performance and observance of all such duties and obligations by such Affiliate.

 

Neither Party shall transfer to a Third Party (other than a permitted assignee of this Agreement) title to or ownership of any Patents within such Party’s Compound-specific Patents (i.e., the Xencor Compound-Specific Patents or the Amgen and Joint Compound-Specific Patents, as applicable) relating to a Compound or Product and licensed (or required to be licensed) to the other Party hereunder, without the other Party’s prior written consent, not to be unreasonably withheld.  Xencor shall not transfer to a Third Party (other than a permitted assignee of this Agreement) title to or ownership of, any Patent within the Xencor CD19 Patents or Xencor Background Patents, if such Patent covers a Compound or a Product, unless such Third Party expressly takes such Patent subject to the License (and agrees to similarly obligate any further assignee).  In addition, if Xencor requests in writing within [...***...] after a termination of this Agreement to which Section 9.7(c) applies, Amgen shall not transfer to any Third Party any Amgen Blocking Patent specified in such request by Xencor, unless such Third Party expressly takes such Patent subject to Xencor’s license under Section 9.7(c)(ii) (and agrees to similarly obligate any further assignee).  Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of each Party, its successors and permitted assigns.  Any assignment of this Agreement in contravention of this Section 13.8 shall be null and void.
