For clarity, the foregoing proviso shall not grant Regeneron rights under the Regeneron Intellectual Property and Regeneron’s interest in the Joint Intellectual Property to sell or offer for sale the Licensed Products in the Field in the Territory. The foregoing license grant shall not preclude Regeneron from, and Regeneron retains all rights with respect to, using or otherwise exploiting, or granting any Person the right to use or otherwise exploit, Regeneron Intellectual Property and Regeneron’s interest in the Joint Intellectual Property for the making, having made, importing, using, selling and offering for sale (a) the Licensed Compound and Licensed Products solely for use outside the Field in the Territory and (b) products (other than Licensed Products) for use with Licensed Products in the Field in the Territory.

Property and Regeneron Trademarks are sublicensable with the prior written consent of Regeneron, which consent shall not be unreasonably withheld, conditioned or delayed outside of the United States; provided, however, that nothing shall prevent Aventis from sublicensing its rights to a Distributor to sell or offer to sell the Licensed Product in the Field in the Territory (other than the United States). For the avoidance of doubt, Regeneron may withhold such consent if Regeneron reasonably determines such sublicense would reduce its financial return from this Agreement in the applicable country. Aventis shall remain responsible and liable for the compliance by its Affiliates and its and their permitted sublicensees and Distributors with applicable terms and obligations set forth herein, including payment under this Agreement and the Supply Agreement with respect to Net Sales of Licensed Products in the Field by such Affiliates, sublicensees or Distributors.

In the event of a breach by a sublicensee, Distributor or a Third Party contractor of any sublicense or subcontract granted or awarded hereunder by Aventis which has or is reasonably likely to have a material adverse effect on Regeneron or the Regeneron Intellectual Property or Regeneron Trademarks, then Regeneron may cause Aventis to exercise, and Aventis will promptly exercise, any termination rights it may have under the sublicense or subcontract with such sublicensee, Distributor or Third Party contractor. All sublicenses and subcontracts granted under this Agreement will terminate upon termination or expiration of this Agreement.

5.3    Additional Development Activities. At Aventis’s request, Regeneron shall continue to provide support with regard to VEGF Trap anti-drug antibody dosing in biological samples measurement subject to Aventis prior approval of the associated costs, which costs shall be Regeneron Costs and shall be reimbursed by Aventis pursuant to Section 9.5; other Development activities may be performed by Regeneron as discussed and agreed between the Parties.

(c)    Aventis may otherwise elect to establish an alternative source, for the manufacture of Formulated Bulk Licensed Product for the supply of Commercial Supply Requirements and Clinical Supply Requirements of Licensed Products in the Territory (x) through one of its other existing manufacturing facilities, (y) by constructing and obtaining all required approvals and validations by Regulatory Authorities for a new manufacturing facility or (z) with Regeneron’s prior consent (which consent shall not be unreasonably withheld, conditioned or delayed), through a Third Party manufacturer other than [****], in each case ((x), (y) and (z)), at Aventis’ own expense.
(d)    All costs and expenses (including capital expenditures) required to provide additional manufacturing capacity pursuant to Sections 8.2(b) and 8.2(c), including without limitation the related start-up and validation activities and the transfer of the manufacturing process for the Licensed Products from Regeneron (or its Affiliates) to Aventis or a Third Party manufacturer, shall be paid solely by Aventis.
8.3    Funded Assets. Notwithstanding anything to the contrary in the Funded Assets MOU, the Parties acknowledge and agree that all title to the Funded Assets (as defined in the Funded Assets MOU) has transferred to Regeneron and Regeneron has no further obligations to Aventis or its Affiliates with respect to the Funded Assets under the Funded Assets MOU.
ARTICLE 9
PAYMENTS
9.1    Payments. Aventis or SWI shall make payments to Regeneron or its Affiliates under this Agreement and the Supply Agreement pursuant to this ARTICLE 9.

33



9.2    Development Balance; Other Payment Obligations. Notwithstanding anything to the contrary in this Agreement or the Supply Agreement, the Development Balance due and owing by Regeneron to Aventis as of the Amendment Effective Date shall be extinguished and cancelled, without any further act of either Party and there shall be no further accrual of the Development Balance following the Amendment Effective Date. Without limiting the foregoing, nothing in this Agreement shall relieve either Party of any payment obligations arising prior to the Amendment Effective Date. From and after the Amendment Effective Date, Aventis shall be solely responsible for all costs and expenses associated with the Development and Commercialization of the Licensed Products in the Field in the Territory and Regeneron shall have no obligation to reimburse Aventis for any costs or expenses incurred by or on behalf of Aventis in connection with the Development and Commercialization of the Licensed Products in the Territory after the Amendment Effective Date.
9.3    Net Sales Report. Within twenty (20) days after the end of each Calendar Quarter, Aventis shall calculate and report to Regeneron the amount of Net Sales, that are attributable to the Licensed Product in each country in the Territory during such Calendar Quarter (including such amount expressed in local currency and as converted into U.S. Dollars in accordance with Section 9.9). Without limiting the generality of the foregoing, Aventis shall require its Affiliates and its and their sublicensees and Distributors to calculate and account for their Net Sales and to provide such reports with respect thereto, in sufficient detail and at such time so that Aventis can meet its obligations to Regeneron hereunder if such sales were made by Aventis.
9.4    Third Party Payment Amounts. Aventis shall be solely responsible for paying all Third Party Payment Amounts, or reimbursing Regeneron on a Calendar Quarter-by-Calendar Quarter basis pursuant to Section 9.8 for any Third Party Payment Amount made by Regeneron, in each case pursuant to the terms of this Section 9.4. Aventis shall, in addition to the Net Sales Report provided pursuant to Section 9.3, provide Regeneron within forty-five (45) days after the end of each Calendar Quarter with deductions taken to arrive at Net Sales and all other information necessary to satisfy Regeneron’s obligations with respect to any Third Party Payment Amounts under any Existing License or New License to which Regeneron is a party. Notwithstanding the Genentech Settlement Letter, the Parties acknowledge and agree that Aventis shall be responsible for making, and shall make, all payments due under the Genentech Settlement Agreement directly to Genentech, Inc. (and not to Regeneron pursuant to this Section 9.4).
9.5    Regeneron Costs. Subject to Section 5.2, Aventis shall, on a Calendar Quarter-by-Calendar Quarter basis pursuant to Section 9.8, reimburse Regeneron for all of the Regeneron Costs incurred by Regeneron after the Amendment Effective Date; provided, however, that for any Regeneron Costs incurred by Regeneron for the benefit of both Licensed Product and any Excluded Ocular VEGF Product, Aventis shall only be required to reimburse [****] of such Regeneron Costs. Regeneron shall provide Aventis all such information related to Regeneron Costs for a Calendar Quarter within forty-five (45) days after the end of each Calendar Quarter.
9.6    Profit Sharing Payment.

34



(a)    The Parties acknowledge and agree that in order to ease the administrative and accounting burdens on the Parties under this Agreement and to provide for the commercial supply of Licensed Products, they have elected to forego the calculation of net profits from sale of Licensed Product and the sharing of net profits under this Agreement, and the associated reporting, reimbursement and reconciliation processes, and instead have agreed that Aventis or SWI shall make payments to Regeneron (or its Affiliate) under this Agreement and the Supply Agreement based on a simplified profit sharing arrangement calculated as a percentage of Net Sales, as set forth in this Section 9.6. Such payments are, in part, intended to reflect the value contributed by Regeneron with respect to its discovery of the VEGF Trap and the development and commercialization of the Licensed Products. For clarity, in the event that the Supply Agreement is terminated for any reason, Aventis shall continue to be obligated to make payments to Regeneron under this Section 9.6 in accordance with the terms hereof.
(b)    Aventis shall pay to Regeneron, on a Calendar Quarter-by-Calendar Quarter basis pursuant to Section 9.8, a percentage of the aggregate Net Sales of all Licensed Products in the Field in the Territory during each Contract Year (each such quarterly payment, a “Profit Sharing Payment”), which percentage shall be based on the aggregate Net Sales of all Licensed Products in the Field in the Territory during such Contract Year as set forth in the chart below (the aggregate amount of such payment due with respect to Net Sales in a given Contract Year, the “Aggregate Profit Sharing Payment”).
Aggregate Net Sales of Licensed Products in the Field in the Territory during each Contract Year
Percentage of Aggregate Net Sales
Aggregate annual Net Sales of Licensed Products less US$[****]
15%
Aggregate annual Net Sales of Licensed Products equal to or greater than US$[****] but less than US$ [****]
[****]
Aggregate annual Net Sales of Licensed Products equal to or greater than US$[****] but less than US$ [****]
[****]
Aggregate annual Net Sales of Licensed Products equal to or greater than US$[****] but less than US$ [****]
[****]
Aggregate annual Net Sales of Licensed Products equal to or greater than US$[****]
30%

By way of example, if aggregate Net Sales of all Licensed Products in the Field in the Territory in a Contract Year are US$ 600,000,000, the Aggregate Profit Sharing Payment in respect of such Contract Year shall be equal to [****]% Net Sales of US$ 600,000,000 (i.e., US$ [****]), which example is described in greater detail in Schedule 10.
(c)    The Profit Sharing Payment due in respect of a given Calendar Quarter shall be equal to (i) the amount of the Aggregate Profit Sharing Payment owed to Regeneron with respect to Net Sales in such Contract Year through the end of such Calendar Quarter

35



(“Cumulative Net Sales”), less (ii) the amount of the Aggregate Profit Sharing Payment, if any, already paid to Regeneron with respect to Cumulative Net Sales in prior Calendar Quarters of such Contract Year.
9.7    Payments with respect to Batches under the Supply Agreement. Regeneron shall sell to SWI, and SWI shall purchase from Regeneron, during the Supply Term, the Product at the following price, payable as follows:
(a)    Regeneron shall invoice SWI for the Estimated Fully Burdened Batch Price applicable to each Batch that was manufactured and shipped pursuant to a Firm Order under the Supply Agreement, and SWI shall pay such amount within forty-five (45) days after the date of such invoice. Beginning in the 2016 Contract Year, within forty-five (45) days after the end of each Calendar Quarter, Regeneron shall provide a good faith estimate of the Aggregate Actual Fully Burdened Manufacturing Cost for that Contract Year.
(b)    With respect to Batches to be manufactured in the 2016 Contract Year and each Contract Year thereafter during the Supply Term, Regeneron shall provide in writing to SWI by [****] Regeneron’s good faith estimate of the Actual Fully Burdened Manufacturing Costs of any Batch to be manufactured in such Contract Year, which estimate shall be based on the Actual Fully Burdened Manufacturing Cost of prior years, current year-to-date manufacturing costs, the number of Batches expected to be manufactured in such Contract Year, and any other relevant factors (the “Estimated Fully Burdened Batch Price”). The Estimated Fully Burdened Batch Prices for the 2014 Contract Year and the 2015 Contract Year are set forth in Appendix 1.
(c)    Beginning with Product manufactured in the 2016 Contract Year, clauses (i), (ii) and (iii) of this Section 9.7(c) shall apply:
(i)    Within sixty (60) days after the end of each Contract Year during the Supply Term, Regeneron shall calculate and provide SWI with (A) (1) the total Actual Fully Burdened Manufacturing Cost for all quantities of Product manufactured during such Contract Year pursuant to a Firm Order, [****], and the cost of any Batches that were [****], and (2) amounts due to Regeneron in respect of quantities of Product in respect of a Firm Order which [****] (the sum of (1) and (2) the “Aggregate Actual Fully Burdened Manufacturing Cost”), (B) the total amount of the payments based on the Estimated Fully Burdened Batch Price for such Contract Year that have been invoiced to SWI (the “Payment Total”), which shall equal the product of (x) the number of Batches that were manufactured during such Contract Year [****] (the “Batch Number”), and (y) the Estimated Fully Burdened Batch Price for such Contract Year, and (C) the amount equal to the difference between the Aggregate Actual Fully Burdened Manufacturing Costs and the Payment Total (the “Reconciliation Amount”). In the event that, with respect to a Contract Year, the Aggregate Actual Fully Burdened Manufacturing Cost is greater than the Payment Total, then Regeneron shall invoice SWI for the Reconciliation Amount. In the event that, with respect to a Contract Year, the Payment Total is greater than the Aggregate Actual Fully Burdened Manufacturing Cost, then SWI shall invoice Regeneron for the Reconciliation Amount. Any invoice prepared pursuant to the foregoing two sentences will be prepared by the appropriate Party within ten (10) days of receipt by SWI of the report containing the Reconciliation Amount. The Party receiving an invoice pursuant to the foregoing three

36



sentences shall pay the Reconciliation Amount within thirty (30) days after the date of such invoice.
(ii)    With regard to Batches manufactured in any given Contract Year within the Supply term, which [****], Regeneron shall invoice SWI for their Actual Fully Burdened Manufacturing Cost and SWI shall pay such amount within forty-five (45) days after the date of such invoice.
(iii)    For clarity, with respect to any Batches manufactured in a given Contract Year but shipped after the end of such Contract Year, Regeneron shall invoice SWI, in accordance with Section 9.7(a) and pursuant to Section 9.8, the amount of the Estimated Fully Burdened Batch Price in effect during the Contract Year in which such Batch was manufactured, regardless of whether a Reconciliation Payment was made by either Party under this Section 9.7(c). To the extent any Batches manufactured in a given Contract Year are shipped after [****], (i) Regeneron shall invoice SWI for their Estimated Fully Burdened Manufacturing Cost, (ii) SWI shall pay such amount within forty-five (45) days after the date of such invoice and (iii) any Reconciliation Amount payable on such batches shall be carried forward to the reconciliation for the subsequent year and added to the Reconciliation Amount to be calculated for such year pursuant to Section 9.7(c)(i). For further clarity, in no event shall this Section 9.7(c) diminish Aventis’s obligations to provide Firm Orders pursuant to Section 5.1 of the Supply Agreement.
9.8    Quarterly Invoicing and Payment. Following the end of each Calendar Quarter, within fifteen (15) days after receipt by Regeneron of the Net Sales Report from Aventis pursuant to Section 9.4, Regeneron shall invoice Aventis the following amounts due for such Calendar Quarter: (i) all Third Party Payment Amounts due in respect of such Calendar Quarter pursuant to Section 9.4, (ii) the amount of Regeneron Costs incurred by Regeneron in such Calendar Quarter which are due pursuant to Section 9.5, and (iii) the amount of the Profit Sharing Payment due with respect to such Calendar Quarter pursuant to Section 9.6 and in accordance with the form of calculation set forth on Schedule 10. Aventis shall pay the amount due to Regeneron pursuant to such invoice(s) within twenty five (25) days after receipt by Aventis of such invoice(s). For clarity, the receipt date shall be the date any invoice is electronically received by Aventis.
9.9    Payment Method and Currency. All payments under this Agreement shall be made by bank wire transfer in immediately available funds to an account designated by the Party to which such payments are due. All sums due under this Agreement shall be payable in United States Dollars. In those cases where the amount due in United States Dollars is calculated based upon one or more currencies other than United States Dollars, such amounts shall be converted to U.S. Dollars using the spot rates the average of the daily spot rates fixed by the European Central Bank from the last Business Day of the preceding month, as published on the website located on the following URL: http://sdw.ecb.europa.eu/browseSelection.do?DATASET=0&sfl1=4&FREQ=M&sfl3=4&CURRENCY=USD&node=2018794. In the event of a payment dispute under this ARTICLE 9, the disputing Party shall be required to pay all non-disputed amounts pursuant to the terms of ARTICLE 9 and may withhold the payment only of any disputed amounts and only during the pendency of any such dispute.

37



9.10    Late Payments    . The Parties agree that, unless otherwise mutually agreed by the Parties or otherwise provided in this Agreement, amounts due by one Party to the other shall be payable to a bank account, details of which are to be communicated by the receiving Party. Unless otherwise mutually agreed by the Parties or otherwise provided in this Agreement, all payments under this Agreement shall earn interest, to the extent permitted by applicable Law, from the date due until paid at a rate equal to one month London Inter-Bank Offering Rate (LIBOR) U.S. Dollars, as quoted on Thomson Reuters Eikon (or any other source agreed to by the Parties) effective for the date on which the payment was due, [****] (such sum being referred to as the “Default Interest Rate”).
9.11    Taxes. Any withholding or other taxes that either Party or its Affiliates are required by Law to withhold or pay on behalf of the other Party, with respect to any payments to such other Party hereunder or the Ancillary Agreements, shall be deducted from such payments and paid to the appropriate tax authority contemporaneously with the remittance to the other Party; provided, however, that the withholding Party shall furnish the other Party with proper evidence of the taxes so paid. Each Party shall cooperate with the other and furnish the other Party with appropriate documents to secure application of the most favorable rate of withholding tax under applicable Law (or exemption from such withholding tax payments, as applicable).
All amounts due under this ARTICLE 9 are exclusive of sales, use, goods and services, value added, excise, and other taxes, duties or charges of a similar nature imposed by any Governmental Authority, or other taxing authority. If any sales, use, goods and services, value added, excise, and other taxes, duties or charges of a similar nature will be chargeable with respect to payments made under this ARTICLE 9, Aventis shall pay to, or upon receipt of invoice from Regeneron, shall reimburse, Regeneron these in addition to the sums otherwise payable, at the rate in force at the due time for payment or such other time as is stipulated under the relevant legislation.
ARTICLE 10
DISPUTE RESOLUTION
10.1    Resolution of Disputes. The Parties recognize that disputes as to certain matters may from time to time arise which relate to either Party’s rights and obligations hereunder. It is the objective of the Parties to comply with the procedures set forth in this Agreement to use all reasonable efforts to facilitate the resolution of such disputes in an expedient manner by mutual agreement.
10.2    Legal Disputes. The Parties agree that, subject to Sections 10.4 and 16.4, they shall use all reasonable efforts to resolve any Legal Dispute arising under this Agreement by good faith negotiation and discussion. In the event that the Parties are unable to resolve any such Legal Dispute either Party may submit the Legal Dispute to the Executive Officers for resolution, specifying the nature of the Legal Dispute with sufficient specificity to permit adequate consideration by such Executive Officers. The Executive Officers shall diligently and in good faith attempt to resolve the referred Legal Dispute within thirty (30) days of receiving such written notification. Any final decision mutually agreed to by the Executive Officers shall be conclusive and binding on the Parties. In the event the Executive Officers are unable to resolve

38



any such Legal Dispute, the Parties shall be free to pursue any rights and remedies available to them at law, in equity or otherwise.
10.3    Escalation to Executive Officers. In the event of a dispute between the Parties with respect to any Development activities or any proposed amendment to the Development Plan pursuant to Section 5.2, either Party may, on written notice to the other Party, refer such dispute to the Executive Officers for a joint decision, specifying the nature of the dispute with sufficient specificity to permit adequate consideration by such Executive Officers. The Executive Officers shall diligently and in good faith attempt to resolve the referred dispute within thirty (30) days of receiving such written notification. Any final decision mutually agreed to by the Executive Officers shall be conclusive and binding on the Parties. In the event that the Executive Officers are unable during such thirty (30)-day period to resolve a dispute between the Parties with respect to whether or not any Development activities or any proposed amendment to the Development Plan may be reasonably expected to have an adverse impact on an Excluded Ocular VEGF Product anywhere in the world, Regeneron’s Executive Officer shall have final decision-making authority. In the event that the Executive Officers are unable during such thirty (30)-day period to resolve a dispute between the Parties with respect to any Development activities or any proposed amendment to the Development Plan other than a dispute with respect to whether or not any Development activity or proposed amendment to the Development Plan may be reasonably expected to have an adverse impact on an Exclude Ocular VEGF Product anywhere in the world, Aventis’ Executive Officer shall have the final decision-making authority.

Notwithstanding the foregoing, in the event Aventis elects not to register, or to prosecute or maintain any registration or registration application for, any Aventis Trademark or any Regeneron Trademark for the Licensed Products in the Territory, Regeneron shall have the right to do so on behalf of Aventis for use with the Licensed Products in the Field during the Term, subject to consultation and cooperation with Aventis. The Parties agree that Aventis shall be solely responsible for [****] costs and expenses incurred in connection with the prosecution and maintenance of the Aventis Trademarks and the Regeneron Trademarks during the Term, except in the event that Regeneron elects to assume responsibility for the prosecution and maintenance of any Aventis Trademark or Regeneron Trademark, in which case Regeneron shall bear [****] of all costs and expenses incurred in prosecuting and maintaining such Aventis Trademark or Regeneron Trademark.
11.5    License to the Licensed Product Trademarks. Regeneron hereby grants to Aventis a license to use the Regeneron Trademarks to manufacture, Develop and Commercialize the Licensed Products in the Territory pursuant to this Agreement and subject to the terms and conditions of this Agreement. Aventis’ rights under this Section 11.5 may be sublicensed, but only to its Affiliates and permitted sublicensees and Distributors pursuant to the terms of Section 4.3 for the purposes of, and subject to the terms and conditions of, this Agreement. Except as provided in this Agreement, neither Party shall have rights in or to the other Party’s Product Trademarks or the goodwill pertaining thereto. Aventis shall utilize the Regeneron Trademarks only on approved Promotional Materials or other approved product-related materials for the Licensed Products for the purposes contemplated herein. All use by Aventis or its Affiliates or permitted sublicensees or Distributors of the Regeneron Trademark(s) shall be in accordance with such quality standards and trademark usage guidelines established by Regeneron that it deems reasonably necessary to preserve its rights in, and the validity and enforceability of, the Regeneron Trademark(s), including any registration and registration application therefor, and the goodwill therein, and which Regeneron may modify and supplement from time to time upon written notice thereof to Aventis, and all goodwill generated through such use shall inure to the sole benefit of Regeneron for the purposes of trademark and trade name ownership, registration, enforcement and maintenance. Each Party agrees that at no time during the Term will it or any of its Affiliates attempt to use or register any trademark, trade dress, service mark, trade name or domain name or social media identifier that is confusingly similar to, misleading or deceptive with respect to the other Party’s Product Trademark(s) for the Licensed Products or take any action or do any act that endangers, damages, dilutes, destroys or similarly affects, in any material respect, the other Party’s trademark or the value of the goodwill pertaining thereto or attack, dispute or contest the validity of or ownership of the other Party’s Product Trademark(s) or any registrations or pending registration thereof. Aventis agrees that upon termination or expiration of the Term, it will discontinue forthwith all use of the Regeneron Trademark. Upon request by Aventis, Regeneron shall (or shall cause its Affiliates, as appropriate, to) execute such

40



documents as may reasonably be required for the purpose of recording with any Governmental Authority the license referred to above in this Section 11.5.
11.6    Use of Corporate Names.
(a)    Aventis shall not use Regeneron’s or its Affiliates’ corporate names or logos on any Promotional Materials related to the Licensed Products (including, without limitation, congress booths or Promotional Materials used or distributed in connection with the applicable Licensed Product) in the Field or otherwise in the Territory; provided, however, that Aventis shall (i) be permitted to identify Regeneron (or its Affiliate) as the manufacturer of the Licensed Products in any such materials to the extent required under any applicable Law and for so long as Regeneron or its Affiliate is supplying Licensed Products to Aventis or its Affiliates under the Supply Agreement and (ii) use Commercially Reasonable Efforts to include in any such materials the phrase “ZALTRAP was developed in collaboration with Regeneron Pharmaceuticals, Inc.” or similar language to the extent permitted under any applicable Law, in each case ((i) and (ii)), consistent with the provisions of Section 11.5.
(b)    Accordingly, unless Regeneron has terminated this Agreement pursuant to Sections 19.3, 19.4, 19.5 or 19.6 or Aventis has terminated this Agreement pursuant to Section 19.2, Regeneron hereby grants to Aventis (and its Affiliates) a non-exclusive license, with the right to grant sublicenses in accordance with Section 4.3, to use Regeneron’s corporate names or logos solely as provided in this Section 11.6 during the Term and thereafter for a maximum period of two (2) years solely to the extent necessary to exhaust the existing inventory of Licensed Product and such materials containing Regeneron’s corporate names or logos. Without limiting the foregoing, Aventis shall not and shall not permit its Affiliates or its or their sublicensees or Distributors to, (m) use in their respective businesses, any trademark that is confusingly similar to, misleading or deceptive with respect to or that dilutes any (or any part) of Regeneron’s corporate names or logos, (n) take any action or do any act that endangers, damages, dilutes, destroys or similarly affects, in any material respect, Regeneron’s corporate names or logos or the value of goodwill pertaining thereto, or (o) attack, dispute or contest the validity of or ownership of Regeneron’s corporate names or logos anywhere in the Territory or any registrations or any pending registration thereof. Aventis agrees and shall cause its Affiliates and its and their sublicensees or Distributors, to conform (y) to the customary industry standards for the protection of the trademarks and to such trademark usage guidelines as Regeneron may furnish from time to time with respect to the use of Regeneron’s corporate names or logos and (z) to adhere to and maintain the highest quality standards of Regeneron with respect to goods sold and services provided under Regeneron’s corporate names or logos.

any priority Patent application at least thirty (30) days prior to the filing of any such priority Patent application by Aventis and consider in good faith any comment; (ii) Aventis shall notify Regeneron prior to the filing of a Patent application by Aventis; (iii) Aventis shall consult with Regeneron following the filing of the priority Patent application in sufficient time to permit the Parties to mutually determine in which countries it shall file convention Patent applications; (iv) Aventis shall provide Regeneron promptly with copies of all communications received from or filed in patent offices with respect to such filings; and (v) Aventis shall provide Regeneron a reasonable time prior to taking or failing to take action that would affect the scope or validity of rights under any Aventis Patent Rights (including but not limited to substantially narrowing or canceling any claim without reserving the right to file a continuing or divisional Patent application, abandoning any Patent or not filing or perfecting the filing of any Patent application in any country), with notice of such proposed action or inaction so that it has a reasonable opportunity to review and make comments, and take such actions as may be appropriate in the circumstances. In the event that Aventis desires to abandon any Patent included in the Aventis Patent Rights, Aventis shall provide reasonable prior written notice to Regeneron of such intention to abandon (which notice shall, in any event, be given no later than sixty (60) days prior to the next deadline for any action that may be taken with respect to such Aventis Patent Right with the applicable patent office) and Regeneron shall have the right, but not the obligation, to assume responsibility for the prosecution and maintenance thereof in Aventis’ name, unless, with respect to any such Patent applications that are unpublished, Aventis notifies Regeneron that Aventis would prefer to maintain the subject matter of such Patent application as a trade secret.
(c)    The Parties shall consult with each other regarding the filing, prosecution and maintenance of any Joint Patent Rights, and responsibility for such activities shall be the obligation of the Controlling Party.

The Controlling Party shall have the following obligations with respect to the filing, prosecution and maintenance of the Joint Patent Rights: (i) the Controlling Party shall use Commercially Reasonable Efforts to provide any priority Patent application at least thirty (30) days prior to the filing of any such priority Patent application by the Controlling Party and consider in good faith any comment from the non-Controlling Party; (ii) the Controlling Party shall notify the non-Controlling Party prior to the filing of a Patent application by the Controlling Party; (iii) the Controlling Party shall consult with the non-Controlling Party following the filing of the priority Patent application in sufficient time to permit the Parties to mutually determine in which countries it shall file convention Patent applications; (iv) the Controlling Party shall provide the non-Controlling Party promptly with copies of all communications received from or filed in patent offices with respect to such filings; and (v) the Controlling Party shall provide the non-Controlling Party a reasonable time prior to taking or failing to take action that would affect the scope or validity of rights under any Joint Patent Rights (including but not limited to substantially narrowing or canceling any claim without reserving the right to file a continuing or divisional Patent application, abandoning any Patent or not filing or perfecting the filing of any Patent application in any country), with notice of such proposed action or inaction so that the non-Controlling Party has a reasonable opportunity to review and make comments, and take such actions as may be appropriate in the circumstances. In the event that the Controlling Party materially breaches the foregoing

44



obligations and such breach is not cured within thirty (30) days of a written notice from the non-Controlling Party to the Controlling Party describing such breach, or in the event that the Controlling Party fails to undertake the filing of a Patent application within ninety (90) days of a written request by the non-Controlling Party to do so, the non-Controlling Party may assume the Controlling Party’s responsibility for filing, prosecution and maintenance of any such Joint Patent Right, and will thereafter be deemed the Controlling Party for purposes hereof (and will undertake such filings, prosecutions and maintenance in such Party’s name). Notwithstanding the foregoing, the Controlling Party may withdraw from or abandon any Joint Patent Rights on thirty (30) days’ prior notice to the other Party, providing the non-Controlling Party the right to assume the prosecution or maintenance thereof in such non-Controlling Party’s name and cost and expense.
(d)    All Out-of-Pocket Costs incurred in the filing, prosecution and maintenance of any Aventis Patent Rights, Regeneron Patent Rights and Joint Patent Rights, and any extensions thereof pursuant to Section 12.2(e)(e), shall be [****], except to the extent that the prosecuting Party elects to abandon the applicable Aventis Patent Right, Regeneron Patent Right or Joint Patent Right, in which case the other Party shall bear [****] of such Out-of-Pocket Costs if such other Party elects to assume responsibility for the prosecution and maintenance thereof as provided herein.
(e)    Each Party agrees to cooperate with the other with respect to the preparation, filing, prosecution and maintenance of the Regeneron Patent Rights, Aventis Patent Rights and Joint Patent Rights pursuant to this Section 12.2, including, without limitation, the execution of all such documents and instruments and the performance of such acts (and causing its relevant employees to execute such documents and instruments and to perform such acts) as may be reasonably necessary in order to permit the other Party to continue any preparation, filing, prosecution or maintenance of Joint Patent Rights that such Party has elected not to pursue as provided for in Section 12.2(c). The Parties shall cooperate to determine for which of the Aventis Patent Rights, Regeneron Patent Rights and Joint Patent Rights to seek an extension of the term in the Territory.

12.3    Interference, Opposition and Reissue.
(a)    Each Party will notify the other within ten (10) days of receipt by such Party of information concerning the request for, or filing or declaration of, any interference, opposition, post-grant review, reissue or reexamination relating to Regeneron Patent Rights, Aventis Patent Rights, or Joint Patent Rights in the Territory. The Parties will thereafter consult and cooperate fully to determine a course of action with respect to any such proceeding. Decisions on whether to initiate such a proceeding and the course of action in such proceeding, including settlement negotiations and terms, will be made (i) with respect to Regeneron Patent Rights, by Regeneron in consultation with Aventis, (ii) with respect to Aventis Patent Rights, by Aventis in consultation with Regeneron, and (iii) with respect to Joint Patent Rights, jointly by the Parties.

13.1    Enforcement of Patents and Product Trademarks.
(a)    In the event that either Party or any of its Affiliates becomes aware of an actual or suspected infringement or unauthorized use, as applicable, of a Aventis Patent Right, a Regeneron Patent Right, a Joint Patent Right or any Product Trademark, in each case, by a Third Party’s activities in the Territory (an “Infringement”), the Party that became aware of the Infringement shall promptly notify the other Party in writing and shall provide such other Party with all available evidence supporting such Infringement. As soon as reasonably practicable after the receipt of such notice, the Parties shall meet and consider the appropriate course of action with respect to such infringement.
(b)    With respect to any Infringement, (i) Regeneron shall have the first right to bring and control any action or proceeding with respect to Infringement of any Regeneron Patent Right or of any Joint Patent Right that [****], and (ii) Aventis shall have the first right to bring and control any action or proceeding with respect to Infringement of any Aventis Patent Right or Joint Patent Right other than a Joint Patent Right that [****] (the Party with the first right being referred to as the “Lead Litigation Party”); provided, however, that the Parties shall ensure that there is proper communication and coordination of activities between the Parties. If the Lead Litigation Party fails to bring any such action or proceeding with respect to Infringement of the applicable Patent by a Third Party within sixty (60) days following notice of the alleged infringement (or such other period of time as may be required by applicable Law), the non-Lead Litigation Party shall have the right to bring and control any such action at its own expense by providing written notice to the other Party (the Party who controls the litigation to be referred to as the “Litigation Party”). The non-Litigation Party will provide reasonable assistance to the Litigation Party in prosecuting any action, and if required by Law, will join in the action. Although the Litigation Party has the right to select counsel of its own choice, it shall first consult with the other Party and consider in good faith the recommendations of the other Party.

46



The non-Litigation Party shall have the right to (and, if required by Law, will) join in any litigation using counsel of its choice at its sole discretion and expense, subject to Section 13.1(c). The amount of any recovery from any such Infringement action shall be (i) retained [****] and (ii) [****], provided that any such recoveries shall be first allocated to [****]. Notwithstanding the foregoing, any recoveries for lost sales or lost profits of a product for any Infringement hereunder shall be (A) with respect [****] and (B) with respect to [****].
(c)    All Out-of-Pocket Costs (except for the expenses of the non-Litigation Party’s counsel, if any) incurred in connection with any Infringement litigation under Section 13.1(b) shall be (i) borne [****], (ii) borne [****], (iii) [****], and (iv) to the extent not otherwise covered in clauses (i) - (iii), borne [****].
(d)    For the avoidance of doubt, neither Party will enter into any settlement of any Infringement suit referenced in this Section 13.1 involving Licensed Products that materially adversely affects the other Party’s rights or obligations with respect to the applicable Licensed Product (with respect to Regeneron as the settling party) or the VEGF Products (with respect to Aventis as the settling party), as applicable in the Territory without the other Party’s prior written consent.
13.2    Patent Marking. Aventis shall comply with the patent marking statutes in each county in which a Licensed Product is made, offered for sale, sold or imported by such Party, its Affiliates and/or its or their sublicensees or Distributors.
13.3    Third-Party Infringement Claims.
(a)    If either Party or its Affiliates becomes aware of a claim or assertion that the manufacture, Development or Commercialization of any Licensed Product in the Field infringes or otherwise violates the intellectual property rights of any Third Party in the Territory such Party shall promptly notify the other Party in writing of this claim or assertion. As soon as reasonably practicable after the receipt of such notice, the Parties shall meet and consider the appropriate course of action with respect to such allegation of infringement.
(b)    The Parties shall cooperate, share all material notices and filings in a timely manner, provide all reasonable assistance to each other and use Commercially Reasonable Efforts to mutually agree upon an appropriate course of action, including, as appropriate, with respect to material court filings and the defense and/or settlement of any such claim; provided, however, that each Party shall have the right to defend and control the defense of any such action naming it as a defendant at its sole cost and expense, using counsel of its own choice; provided further that any counterclaim or defense alleging Infringement (or infringement) shall be governed by Section 13.1. The rights and obligations in this Section 13.3 shall apply even if only one Party defends any claimed infringement action commenced by a Third Party alleging that the manufacture, Development or Commercialization of any Licensed Product in the Field infringes or otherwise violates the intellectual property rights of such Third Party in the Territory.
(c)    Unless otherwise agreed by the Parties, each Party shall bear its own Out-of-Pocket Costs and internal costs (except for the expenses of the non-controlling Party’s

47



cooperation pursuant to Section 13.3(b), if only one Party defends a claim) incurred in connection with any litigation under this Section 13.3.
(d)    For the avoidance of doubt, neither Party will enter into any settlement of any suit involving Licensed Products that materially adversely affects the other Party’s rights or obligations with respect to the applicable Licensed Product (with respect to Regeneron as the settling party) or the VEGF Products (with respect to Aventis as the settling party), as applicable in the Territory without the other Party’s prior written consent.
13.4    Invalidity or Unenforceability Defenses or Actions.
(a)    In the event that a Third Party asserts, as a defense or as a counterclaim in any Infringement action (or infringement action) under Section 13.1, that any Regeneron Patent Rights, Aventis Patent Rights or Joint Patent Rights are invalid or unenforceable, then the Party first becoming aware of such claim shall promptly give written notice to the other Party. Subject to the assistance and coordination provisions described in Section 13.1(b), the Litigation Party shall have the final decision-making authority on responding to such defense or defending against such counterclaim (as applicable), including the right to settle or otherwise compromise such claim, in consultation with the non-Litigation Party.
(b)    If a Third Party asserts, in a declaratory judgment action or similar action or claim filed by such Third Party, that any Regeneron Patent Rights, Aventis Patent Rights or Joint Patent Rights are invalid or unenforceable, then the Party first becoming aware of such action or claim shall promptly give written notice to the other Party. The Party having the final decision-making authority on controlling the defense of such action or claim, including settlement negotiations and terms, will be (i) with respect to Regeneron Patent Rights, Regeneron in consultation with Aventis, (ii) with respect to Aventis Patent Rights, Aventis in consultation with Regeneron, and (iii) with respect to Joint Patent Rights, the Parties jointly. Any such Party controlling the defense against any such action or claim shall use legal counsel mutually agreeable by the Parties, and the Parties shall at all times cooperate, share all material notices and filings in a timely manner, provide all reasonable assistance to each other and use Commercially Reasonable Efforts to mutually agree upon an appropriate course of action, including, as appropriate, the preparation of material court filings and any discussions concerning a potential defense and/or settlement of any such claim.
(c)    All Out-of-Pocket Costs incurred in connection with responding to or defending against any action or claim that any Regeneron Patent Rights, Aventis Patent Rights or Joint Patent Rights are invalid or unenforceable pursuant to this Section 13.4 shall be borne in the same manner as set forth in Section 13.1(c) with respect to the allocation of costs for Infringement litigation.
(d)    For the avoidance of doubt, neither Party will enter into any settlement of any suit referenced in this Section 13.4 that materially adversely affects the other Party’s rights or obligations with respect to Licensed Products (with respect to Regeneron as the settling party) or the VEGF Products (with respect to Aventis as the settling party), as applicable in the

48



Territory, including admitting the invalidity or unenforceability of any Regeneron Patent Rights, Aventis Patent Rights, or Joint Patent Rights, without the other Party’s prior written consent.

Furthermore, each of Aventis and Regeneron acknowledges (subject to the further provisions of this ARTICLE 16) that all New Information is confidential and proprietary to both Parties (and both Parties shall be deemed to be the receiving Party with respect thereto). During the Term and for a period of ten (10) years thereafter, each of Aventis and Regeneron shall, and shall cause its officers, directors, employees and agents to, maintain in confidence and not disclose to any Third Party or not use the Party Information of the other Party (or its Affiliates) and all New Information, except to the extent such disclosure or use is expressly permitted by the terms of this Agreement.

51



(i)    necessary or useful to file, prosecute, enforce or defend Patents or Patent applications for which the Party has the right to assume filing, prosecution, enforcement, defense or maintenance pursuant to this Agreement; provided, however, that reasonable measures shall be taken to assure confidential treatment of such information to the extent practicable and consistent with applicable Law;
(ii)    required by a Governmental Authority, applicable Law (including the rules and regulations of any stock exchange or trading market on which the receiving Party’s (or its parent entity’s) securities are traded) or court order to be disclosed, provided that the receiving Party uses reasonable efforts to give the disclosing Party advance notice of such required disclosure in sufficient time to enable the disclosing Party to seek confidential treatment for such information, and provided further that the receiving Party provides all reasonable cooperation to assist the disclosing Party to protect such information and limits the disclosure to that information that is required by a Governmental Authority, applicable Law or court order to be disclosed;

Such other Party shall have a reasonable opportunity to recommend any changes it reasonably believes are necessary (a) to preserve the New Information or such other Party Information or (b) to enable the Parties to obtain patent protection if either Party deems it necessary), and the Publishing Party shall not unreasonably reject such comments and, if requested by the other Party, shall delay or prevent such disclosure or publication as reasonably proposed by such other Party. In the case of patentable inventions, the delay shall be sufficiently long to permit the timely preparation and filing of a Patent application(s) or application(s) for a certificate of invention on the information involved.

53



however, that, without prior submission to the other Party, either Party may issue press releases or public announcements that incorporate information concerning this Agreement or any Ancillary Agreement or any activities contemplated thereunder which information was included in a press release or public announcement which was previously approved by the other Party as part of a press release or other public disclosure concerning this Agreement or which contains only non-material factual (non-financial) information regarding this Agreement (e.g., that the Agreement remains in effect). Except as otherwise required by applicable Law, the Party whose press release has been reviewed shall remove any information the reviewing Party reasonably deems to be inappropriate for disclosure. In connection with any press release or other written public announcement issued by Aventis pursuant to this Section 16.6, Aventis shall use Commercially Reasonable Efforts to include in any such press release or public announcement the phrase “ZALTRAP was developed in collaboration with Regeneron Pharmaceuticals, Inc.” or similar language to the extent permitted under any applicable Law, consistent with the provisions of Section 11.5.

In furtherance of the foregoing provisions of this Section 16.6, each Party shall give the other Party a reasonable opportunity to review all filings of this Agreement and all filings describing the terms of this Agreement with any Governmental Authority, including without limitation the United States Securities and Exchange Commission, prior to submission of such filings, and shall give due consideration to any reasonable comments by the non-filing Party relating to such filing, including without limitation the provisions of this Agreement for which confidential treatment should be sought.

17.2    Indemnity Procedure.
(a)    The Party entitled to indemnification under this ARTICLE 17 (an “Indemnified Party”) shall notify the Party potentially responsible for such indemnification (the “Indemnifying Party”) within five (5) Business Days of becoming aware of any claim or claims asserted or threatened against the Indemnified Party which could give rise to a right of indemnification under this Agreement; provided, however, that the failure to give such notice shall not relieve the Indemnifying Party of its indemnity obligation hereunder except to the extent that such failure materially prejudices its rights hereunder.
(i)    If the Indemnifying Party has acknowledged in writing to the Indemnified Party the Indemnifying Party’s responsibility for defending such claim, the Indemnifying Party shall have the right to defend, at its sole cost and expense, such claim by all appropriate proceedings, which proceedings shall be prosecuted diligently by the Indemnifying Party to a final conclusion or settled at the discretion of the Indemnifying Party; provided, however, that the Indemnifying Party may not enter into any compromise or settlement unless (i) such compromise or settlement includes as an unconditional term thereof, the giving by each claimant or plaintiff to the Indemnified Party of a release from all liability in respect of such claim; and (ii) the Indemnified Party consents to such compromise or settlement, which consent shall not be withheld or delayed unless such compromise or settlement involves (A) any admission of legal wrongdoing by the Indemnified Party, (B) any payment by the Indemnified Party that is not indemnified hereunder or (C) the imposition of any equitable relief against the Indemnified Party. If the Indemnifying Party does not elect to assume control of the defense of a claim or if a good faith and diligent defense is not being or ceases to be materially conducted by the Indemnifying Party, the Indemnified Party shall have the right, at the expense of the Indemnifying Party, upon ten (10) Business Days’ prior written notice to the Indemnifying Party of its intent to do so, to undertake the defense of such claim for the account of the Indemnifying Party (with counsel reasonably selected by the Indemnified Party and approved by the Indemnifying Party, such approval not to be unreasonably withheld or delayed), provided, that the Indemnified Party shall keep the Indemnifying Party apprised of all material developments with respect to such claim and promptly provide the Indemnifying Party with copies of all correspondence and documents exchanged by the Indemnified Party and the opposing party(ies) to such litigation. The Indemnified Party may not compromise or settle such litigation without the prior written consent of the Indemnifying Party, such consent not to be unreasonably withheld or delayed.
(ii)    The Indemnified Party may participate in, but not control, any defense or settlement of any claim controlled by the Indemnifying Party pursuant to this Section 17.2 and shall bear its own costs and expenses with respect to such participation; provided, however, that the Indemnifying Party shall bear such costs and expenses if counsel for the Indemnifying Party shall have reasonably determined that such counsel may not properly represent both the Indemnifying and the Indemnified Party.

56



(iii)    Regardless of whether the Indemnifying Party assumes the defense of any claim pursuant to this Section 17.2, the Indemnified Party shall and shall cause each indemnitee to, cooperate in the defense or prosecution thereof and shall furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation shall include access during normal business hours afforded to the Indemnifying Party to and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such claim and making Indemnified Parties and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and to the extent the Indemnified Party is entitled to indemnification pursuant to this ARTICLE 17, the Indemnifying Party shall reimburse the Indemnified Party for all its reasonable and verifiable out-of-pocket expenses in connection with providing such assistance.
ARTICLE 18
FORCE MAJEURE
Neither Party will be held liable or responsible to the other Party nor be deemed to have defaulted under or breached this Agreement or any Ancillary Agreement for failure or delay in fulfilling or performing any term of this Agreement or any Ancillary Agreement when such failure or delay is caused by or results from causes beyond the reasonable control of the affected Party including, without limitation, embargoes, acts of war (whether war be declared or not), insurrections, strikes, riots, civil commotions, or acts of God (“Force Majeure”). Such excuse from liability and responsibility shall be effective only to the extent and duration of the event(s) causing the failure or delay in performance and provided that the affected party has not caused such event(s) to occur. The affected Party will notify the other Party of such Force Majeure circumstances as soon as reasonably practical and will make every reasonable effort to mitigate the effects of such Force Majeure circumstances.
ARTICLE 19
TERM AND TERMINATION
19.1    Term/Expiration of Term.
(a)    The “Term” of this Agreement shall commence on the Effective Date and end at such time as neither Aventis, nor any of its Affiliates or its or their sublicensees or Distributors, is Developing or Commercializing any Licensed Product in the Field anywhere in the Territory (and such cessation of Development and Commercialization activities is acknowledged by both Parties to be permanent), unless earlier terminated as provided hereafter.
(b)    Upon expiration of the Term, except as set forth in this Agreement (including Sections 19.7 and 19.8), all licenses and rights granted by a Party to the other Party hereunder shall automatically terminate and revert to the granting Party.
19.2    Termination Without Cause. Aventis may terminate this Agreement (a) on a country-by-country basis for all Licensed Products in such country on [****] prior written notice to Regeneron or (b) with respect to the entire Territory for all Licensed Products on [****] prior written notice to Regeneron; provided, however, that any termination of this Agreement in five

57



(5) or more of the Original Major Market Countries shall be treated as a termination of this Agreement in its entirety under clause (b). Except as otherwise provided below in this Section 19.2, the Agreement shall continue in full force and effect through the notice period set forth above (the “Termination Notice Period”). During the Termination Notice Period, to the extent set forth or requested in one or more written notices from Regeneron to Aventis hereunder (y) such licenses and rights granted to Aventis shall automatically terminate as of a date specified in such notice(s) (but not later than the Termination Notice Period) in the Terminated Territory and (z) Aventis will promptly take the actions required by Schedule 6 or Schedule 7, as applicable, and Regeneron will reasonably cooperate with Aventis (for avoidance of doubt, such cooperation shall not require Regeneron to pay any amounts or incur any liabilities or obligations not otherwise required hereunder to be paid or incurred by Regeneron) to facilitate Regeneron’s (or its nominee’s) expeditious assumption during the Termination Notice Period, with as little disruption as reasonably possible, of the continued Development and/or Commercialization of such Licensed Product(s) in the Terminated Territory.
19.3    Termination For Material Breach. Upon and subject to the terms and conditions of this Section 19.3, this Agreement shall be terminable by a Party in its entirety if the other Party commits a material breach of this Agreement. Such notice of termination shall set forth in reasonable detail the facts underlying or constituting the alleged breach (and specifically referencing the provisions of this Agreement alleged to have been breached), and the termination which is the subject of such notice shall be effective ninety (90) days after the date such notice is given unless the breaching Party shall have cured such breach within such ninety (90) day period (or, if such material breach, by its nature, is a curable breach but such breach is not curable within such ninety (90) day period, such longer period not to exceed one hundred eighty (180) days so long as the breaching party is using diligent efforts to cure such breach, in which event if such breach has not been cured, such termination shall be effective on the earlier of the expiration of such one hundred eighty (180) day period or such lime as the breaching party ceases to use diligent efforts to cure such breach). Notwithstanding the foregoing, in the case of breach of a payment obligation hereunder, the ninety (90) day period referred to in the second sentence of this Section 19.3 shall instead be thirty (30) days (and the immediately following parenthetical clause in such sentence shall not apply). For purposes of this Section 19.3, the term “material breach” shall mean a breach by a Party that substantially undermines the benefits reasonably expected to be realized by the non-breaching Party from the Collaboration, taken as a whole.
19.4    Termination for Aventis’ Material Breach of the Supply Agreement. In the event that Regeneron (or its Affiliate) terminates the Supply Agreement for Aventis’ (or its Affiliate’s) material breach thereof, Regeneron shall have the right to terminate this Agreement in its entirety upon thirty (30) days’ prior written notice to Aventis.
19.5    Termination for Insolvency. Either Party shall have the right to terminate this Agreement in its entirety if, at any time, (a) the other Party shall file in any court or agency pursuant to any statute or regulation of any state or country, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of the Party or of its assets, or (b) the other Party proposes a written agreement of

58



composition or extension of its debts, or (c) the other Party shall be served with an involuntary petition against it, filed in any insolvency proceeding, and such petition shall not be dismissed within sixty (60) days after the filing thereof, or (d) the other Party shall propose or be a party to any dissolution or liquidation, or (e) if the other Party shall make an assignment for the benefit of creditors.
19.6    Termination for Breach of Investor Agreement. Notwithstanding anything to the contrary herein, Regeneron will have the unilateral right to terminate this Agreement in its entirety, upon written notice to Aventis, if any of the Standstill Parties (as defined in the Amended and Restated Investor Agreement, dated as of January 11, 2014 (the “Investor Agreement”), by and among Aventis, sanofi-aventis US LLC, Aventis, sanofi-aventis Amérique du Nord and Regeneron) shall have breached Section 4.1 of the Investor Agreement. For the avoidance of doubt, Regeneron shall not have the right to terminate this Agreement as a result of a de minimis breach of Section 4.1(a) of the Investor Agreement or an inadvertent breach of Section 4.1(g) of the Investor Agreement arising from informal discussions covering general corporate or other business matters the purpose of which is not intended to effectuate or lead to any of the actions referred to in paragraphs (a) through (e) of Section 4.1 of the Investor Agreement.
19.7    Effect of Termination/Expiration.
(a)    Upon termination of this Agreement in its entirety pursuant to Section 19.2(b), 19.3, 19.4, 19.5 or 19.6, the provisions of Schedule 6 shall apply, and except to the extent required by Aventis to fulfill its obligations pursuant to Schedule 6 (and upon the earlier of such fulfillment or written notice from Regeneron that it will not require such fulfillment, such licenses and rights, to the extent not previously terminated, shall automatically terminate and revert to Regeneron), (i) all licenses and rights granted by Regeneron to Aventis hereunder shall automatically terminate and revert to Regeneron, and (ii) the licenses from Aventis and its Affiliates to Regeneron referred to in Schedule 6 shall come into full force and effect.
(b)    Upon termination of this Agreement with respect to a Terminated Territory pursuant to Section 19.2(a) (but not in the case of any termination of this Agreement in its entirety), the provisions of Schedule 7 shall apply with respect to the Terminated Territory, and except to the extent required by Aventis to fulfill its obligations pursuant to Schedule 7 (and upon the earlier of such fulfillment or written notice from Regeneron that it will not require such fulfillment, such licenses and rights, to the extent not previously terminated, shall automatically terminate and revert to Regeneron), (i) all licenses and rights granted by Regeneron to Aventis hereunder with respect to the Terminated Territory shall automatically terminate and revert to Regeneron, and (ii) the licenses from Aventis and its Affiliates to Regeneron referred to in Schedule 7 with respect to the Terminated Territory shall come into full force and effect. Without limiting the foregoing, in the event that Aventis terminates this Agreement with respect to a Terminated Territory pursuant to Section 19.2(a), Regeneron shall not take any action with respect to the Development and Commercialization of the Licensed Product(s) in the Field in the Terminated Territory that could reasonably be expected to have a materially adverse impact on

59



Aventis’ continued Development and Commercialization of the Licensed Product(s) in the Field in the Territory.
(c)    Without limiting Section 19.8, upon termination of this Agreement, the following provisions of this Agreement shall survive the termination of this Agreement and shall continue to be enforceable: ARTICLE 12 and ARTICLE 13, provided that, with respect to all the countries of the world in the case of termination under Section 19.7(a), and with respect to the Terminated Territory in the case of termination under Section 19.7(b), (i) Regeneron shall have the first right, but not the obligation, to enforce the Aventis Patent Rights in the territory to which such termination applies pursuant to Section 13.1(b); (ii) any costs and expenses incurred in connection with the prosecution and maintenance (including any interference, opposition or reexamination) of the Regeneron Patent Rights, Aventis Patent Rights or Joint Patent Rights in the territory to which such termination applies, or the defense of any claim that any of the foregoing are invalid or unenforceable (excluding the cost of any counsel employed by the non-controlling Party) shall be treated as follows: (1) with respect to the Regeneron Patent Rights and Aventis Patent Rights, the Party controlling the prosecution, maintenance or defense of such Regeneron Patent Rights or Aventis Patent Rights shall be responsible for such costs, except in the event that Regeneron elects to assume responsibility for the prosecution and maintenance of the Aventis Patent Rights pursuant to Section 12.2(b), in which case Regeneron shall be responsible for the costs incurred by Regeneron in connection therewith, and (2) with respect to the Joint Patent Rights, the Parties shall [****]; and (iii) any costs and expenses incurred in connection with the enforcement (and any resulting recoveries) of the Regeneron Patent Rights, Aventis Patent Rights or Joint Patent Rights in the territory to which such termination applies shall be the responsibility of the enforcing Party and the enforcing Party shall retain all recoveries with respect thereto; provided, however, that notwithstanding anything to the contrary in this Section 19.7(c), any recoveries for lost sales or profits of a product from any Infringement action hereunder shall be paid solely to or retained solely by the Party that is selling (or has the right to sell) such product.
19.8    Survival of Obligations. Except as otherwise provided in this ARTICLE 19, Schedule 6 or Schedule 7, upon expiration or termination of this Agreement, the rights and obligations of the Parties hereunder shall terminate to the extent of such expiration or termination, and this Agreement shall cease to be of further force or effect to the extent of such expiration or termination, provided that notwithstanding any expiration or termination of this Agreement:
(a)    neither Aventis nor Regeneron shall be relieved of any obligations (including payment obligations) of such Party arising prior to such expiration or termination, including, without limitation, with respect to Aventis, the payment of any non-cancelable costs and expenses incurred as part of a Plan (even if such costs and expenses arise following termination or expiration, as the case may be), except that in the case of termination of this Agreement pursuant to Section 19.2, without limitation of and subject to Aventis’ continuing obligations under the provisions referred to in Section 19.2, Aventis’ other obligations hereunder shall terminate prior to expiration of the Termination Notice Period if prior to such expiration Regeneron enters into a collaboration agreement of substantially similar scope as, and providing

60



for the assumption and performance by the counterparty thereto of the obligations of Aventis under, this Agreement;
(b)    subject to the provisions of this ARTICLE 19 (including Schedule 6 and Schedule 7 to the extent applicable), the following obligations shall survive the expiration or termination of this Agreement and shall continue to be enforceable: Sections 4.6, 5.5, 6.4, 6.7, 6.10, 6.11, 7.2 (solely with respect to Regeneron and, insofar as necessary to fulfill its ongoing regulatory obligations, Aventis), 7.3(f) and (g) (solely with respect to Aventis’ obligations with respect to Excluded Ocular VEGF Products), 7.4, 7.5, 7.6 (first sentence), 7.7, 8.3, 11.1, 11.3(a), 11.5 (penultimate sentence), 11.6, 15.3, 19.1, 19.2, 19.7 (including Schedule 6 and Schedule 7), 19.8 and ARTICLE 9, ARTICLE 12 and 13 (subject to Section 19.7(c)), ARTICLE 14, ARTICLE 17, and ARTICLE 20 to the extent applicable.
(c)    such expiration or termination and this ARTICLE 19 shall be without prejudice to any rights or remedies a party may have for breach of this Agreement, including, without limitation, any breach of the provisions referred to in clause (b) above; and
(d)    if this Agreement is terminated with respect to the Terminated Territory pursuant to Section 19.2(a) (but not in its entirety), then following such termination the foregoing provisions set forth in this Section 19.8 shall remain in effect with respect to the Terminated Territory (to the extent they would survive and apply in the event this Agreement expires or is terminated in its entirety) and all provisions not surviving in accordance with the foregoing shall terminate upon termination of this Agreement with respect to the Terminated Territory and be of no further force and effect (and for the avoidance of doubt all provisions of this Agreement shall remain in effect with respect to all countries in the Territory other than the Terminated Territory).
ARTICLE 20
MISCELLANEOUS
20.1    Governing Law; Submission to Jurisdiction. This Agreement shall be governed by and construed in accordance with the Laws of the State of New York, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction. Each Party hereby irrevocably and unconditionally consents to the exclusive jurisdiction of the courts of the State of New York, and the United States District Court for the Southern District of New York for any action, suit or proceeding (other than appeals therefrom) arising out of or relating to this Agreement, waives any objections to such jurisdiction and venue and agrees not to commence any action, suit or proceeding relating to this Agreement except in such courts. Each Party further agrees that service of any process, summons, notice or document by registered mail to its address set forth in Section 20.3 shall be effective service of process for any action, suit or proceeding brought against it under this Agreement in any such court.
20.2    Waiver. Waiver by a Party of a breach hereunder by the other Party shall not be construed as a waiver of any subsequent breach of the same or any other provision. No delay or omission by a Party in exercising or availing itself of any right, power or privilege hereunder shall preclude the later exercise of any such right, power or privilege by such Party. No waiver

61



shall be effective unless made in writing with specific reference to the relevant provision(s) of this Agreement and signed by a duly authorized representative of the Party granting the waiver.
20.3    Notices. All notices, instructions and other communications hereunder or in connection herewith shall be in writing, shall be sent to the address of the relevant Party set forth on Schedule 8 attached hereto and shall be (a) delivered personally, (b) sent by registered or certified mail, return receipt requested, postage prepaid, (c) sent via a reputable nationwide overnight courier service, or (d) sent by facsimile transmission, with a confirmation copy to be sent by registered or certified mail, return receipt requested, postage prepaid. Any such notice, instruction or communication shall be deemed to have been delivered upon receipt if delivered by hand, three (3) Business Days after it is sent by registered or certified mail, return receipt requested, postage prepaid, one (1) Business Day after it is sent via a reputable nationwide overnight courier service, or when transmitted with electronic confirmation of receipt, if transmitted by facsimile (if such transmission is made during regular business hours of the recipient on a Business Day; or otherwise, on the next Business Day following such transmission). Either Party may change its address by giving notice to the other Party in the manner provided above.
20.4    Entire Agreement. This Agreement together with the Ancillary Agreements to the extent referred to herein contain the complete understanding of the Parties with respect to the subject matter hereof and thereof and supersedes all prior understandings and writings relating to the subject matter hereof and thereof.
20.5    Amendments. No provision in this Agreement shall be supplemented, deleted or amended except in a writing executed by an authorized representative of each of Aventis and Regeneron.
20.6    Headings. The descriptive headings of Articles and Sections are inserted solely for convenience of reference and are not intended as complete or accurate descriptions of the content of such Articles or Sections.
20.7    Severability. If, under applicable Laws, any provision hereof is invalid or unenforceable, or otherwise directly or indirectly affects the validity of any other material provision(s) of this Agreement in any jurisdiction (“Modified Clause”), then, it is mutually agreed that this Agreement shall endure and that the Modified Clause shall be enforced in such jurisdiction to the maximum extent permitted under applicable Laws in such jurisdiction, provided, further that the Parties shall consult and use all reasonable efforts to agree upon, and hereby consent to, any valid and enforceable modification of this Agreement as may be necessary to avoid any unjust enrichment of either Party and to match the intent of this Agreement as closely as possible, including the economic benefits and rights contemplated herein.
20.8    Registration and Filing of the Agreement. To the extent that a Party concludes in good faith that it is required to file or register this Agreement or a notification thereof with any Governmental Authority in accordance with applicable Laws, such Party may do so subject to the provisions of Section 16.6 above. The other Party shall promptly cooperate in such filing or

62



notification and shall promptly execute all documents reasonably required in connection therewith. The Parties shall promptly inform each other as to the activities or inquiries of any such Governmental Authority relating to this Agreement, and shall promptly cooperate to respond to any request for further information therefrom.
20.9    Assignment. Except as otherwise expressly provided herein, neither this Agreement nor any of the rights or obligations hereunder may be assigned by either Aventis or Regeneron without (a) the prior written consent of Regeneron in the case of any assignment by Aventis or (b) the prior written consent of Aventis in the case of an assignment by Regeneron, except in each case (i) to an Affiliate of the assigning Party, provided that the assigning Party shall remain primarily liable hereunder notwithstanding any such assignment, or (ii) subject to Section 19.6, to any other party who acquires all or substantially all of the business of the assigning Party by merger, sale of assets or otherwise, so long as such Affiliate or other party agrees in writing to be bound by the terms of this Agreement. The assigning Party shall remain primarily liable hereunder notwithstanding any such assignment. Any attempted assignment in violation hereof shall be void.
20.10    Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their respective successors and permitted assigns, and shall also inure to the benefit of the Regeneron Indemnitees and Aventis Indemnitees to the extent provided in the last sentence of Section 20.13.
20.11    Affiliates. Each Party may perform its obligations hereunder through one or more of its Affiliates, although each Party shall nonetheless be responsible for the performance of its Affiliates. Neither Party shall permit any of its Affiliates to commit any act (including any act or omission) which such Party is prohibited hereunder from committing directly.
20.12    Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original but which together shall constitute one and the same instrument. This Agreement may be executed by exchange between the Parties of electronically transmitted signatures (via facsimile, PDF format via e-mail or other electronic means) and such signatures shall be deemed to bind each Party hereto as if they were original signatures.
20.13    Third-Party Beneficiaries. Except as provided below in this Section 20.13, none of the provisions of this Agreement shall be for the benefit of or enforceable by any Third Party including any creditor of any Party hereto. No Third Party shall obtain any right under any provision of this Agreement or shall by reason of any such provision make any claim in respect of any debt, liability or obligation (or otherwise) against any Party hereto. Notwithstanding the foregoing, ARTICLE 17 is intended to benefit, and to be enforceable by, in addition to the Parties, the other Regeneron Indemnitees and Aventis Indemnitees as if they were parties hereto.
20.14    Relationship of the Parties. Each Party shall bear its own costs incurred in the performance of its obligations hereunder without charge or expense to the other except as expressly provided in this Agreement. Neither Aventis nor Regeneron shall have any responsibility for the hiring, termination or compensation of the other Party’s employees or for any employee compensation or benefits of the other Party’s employees. No employee or

63



representative of a Party shall have any authority to bind or obligate the other Party to this Agreement for any sum or in any manner whatsoever, or to create or impose any contractual or other liability on the other Party without said Party’s approval. For all purposes, and notwithstanding any other provision of this Agreement to the contrary, Regeneron’s legal relationship under this Agreement to Aventis, and Aventis’ legal relationship under this Agreement to Regeneron, shall be that of independent contractor. Nothing in this Agreement shall be construed to establish a relationship of partners or joint ventures between the Parties or any of their respective Affiliates.
20.15    Limitation of Damages. IN NO EVENT SHALL REGENERON OR AVENTIS BE LIABLE FOR SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES (INCLUDING, WITHOUT LIMITATION, LOSS OF PROFITS) SUFFERED BY THE OTHER PARTY, REGARDLESS OF THE THEORY OF LIABILITY (INCLUDING CONTRACT, TORT, NEGLIGENCE, STRICT LIABILITY OR OTHERWISE) AND REGARDLESS OF ANY PRIOR NOTICE OF SUCH DAMAGES, EXCEPT TO THE EXTENT ANY SUCH DAMAGES ARE PAID TO A THIRD PARTY AS PART OF A THIRD-PARTY CLAIM WHICH IS COVERED BY THE INDEMNIFICATION OBLIGATIONS IN ARTICLE 17.
20.16    Non-Solicitation. During the Term and for a period of two (2) years thereafter, neither Party shall solicit or otherwise induce or attempt to induce any employees from the other Party involved in the manufacture, Development or Commercialization of any VEGF Product to leave the employment of the other Party and accept employment with the first Party. Notwithstanding the foregoing, this prohibition on solicitation does not apply to actions taken by a Party solely as a result of an employee’s affirmative response to a general recruitment effort carried through a public solicitation or general solicitation.
20.17    Rejection of Agreement in Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by a Party to the other Party are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code and any similar Laws in any other country in the Territory, licenses of rights to “intellectual property” as defined under Section 101(35A) of the U.S. Bankruptcy Code. The Parties agree that all intellectual property rights licensed under or pursuant to this Agreement, including, without limitation, any patents or patent applications in any country of a party covered by the license grants under this Agreement, are part of the “intellectual property” as defined under Section 101 (35A) of the Bankruptcy Code subject to the protections afforded the non-rejecting Party under Section 365(n) of the Bankruptcy Code, and any similar law or regulation in any other country. The Parties agree that this Agreement shall not be deemed terminated by virtue of any rejection by a Party or its receiver or trustee under applicable bankruptcy Laws unless the non-rejecting Party fails to exercise its rights under Section 365(n)(1)(B) of the U.S. Bankruptcy Code (or its foreign equivalents). For clarity, if the non-rejecting Party fails to exercise such rights or such rights are not available in a country outside the United States, this Agreement shall be deemed terminated. 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 or any analogous Laws in any other country or jurisdiction, if this Agreement is not terminated or deemed terminated, the Party hereto that is not the subject of such proceeding shall be entitled to a complete duplicate of (or

64



complete access to, as appropriate) all such intellectual property and all embodiments of such intellectual property, which, if not already in such Party’s possession, shall be promptly delivered to it upon such Party’s written request, unless the Party subject to such proceeding elects to continue to perform all of its obligations under this Agreement.
20.18    Construction.
(a)    The use of words in the singular or plural, or with a particular gender, shall not limit the scope or exclude the application of any provision of this Agreement to such person or persons or circumstances as the context otherwise permits. The words “will” and “shall” shall have the same meaning and the use of the word “or” is used in the inclusive sense (and/or). The term “including,” “include,” or “includes” as used herein shall mean including, without limiting the generality of any description preceding such term, irrespective of whether such term is used with “without limitation” or “without limiting” throughout this Agreement. Whenever this Agreement refers to a number of days, unless otherwise specified, such number refers to calendar days.
(b)    The captions of this Agreement are for convenience or reference only and in no way define, describe, extend or limit the scope of intent of this Agreement or in the intent of any provision contained in this Agreement. Unless otherwise specified, (i) the references in this Agreement to any Article, Section, Schedule or Appendix means references to such Article, Section, Schedule or Appendix of this Agreement, (ii) references in any section to any clause are references to such clause of such section and (iii) references to any agreement, instrument or other document in this Agreement refer to such agreement, instrument or other document as originally executed or, if subsequently varied, replaced or supplemented from time to time, so varied, replaced or supplemented and in effect at the relevant time of reference thereto.
(c)    Whenever a provision of this Agreement requires an approval or consent by a Party to this Agreement and notification of such approval or consent is not delivered within the applicable time limit, then, unless otherwise specified, the Party whose approval or consent is required shall be conclusively deemed to have withheld its approval or consent. This Agreement has been prepared jointly and the provisions contained herein shall not be construed or interpreted for or against any Party to this Agreement because such Party drafted or caused such Party’s legal representative to draft any provision contained herein.
(d)    In the event of any conflict between this Agreement and the Schedules and Appendices hereto, this Agreement shall prevail. In the event of any conflict between this Agreement and the Supply Agreement, this Agreement shall control.

Transition Arrangements Following Termination in its Entirety
1.    Aventis shall promptly collect and return, and cause its Affiliates and its and their sublicensees and Distributors to collect and return, to Regeneron or, at Regeneron’s request, destroy, all documents containing Party Information or New Information directly relating to the Licensed Products, and shall immediately cease, and cause its Affiliates and its and their sublicensees and Distributors to cease, all further use of any such Party Information or New Information with respect to such Licensed Products.

2.    Aventis shall use Commercially Reasonable Efforts to provide all cooperation and assistance reasonably requested by Regeneron to enable Regeneron (or its nominee) to assume with as little disruption as reasonably possible, the continued Development and/or Commercialization of the Licensed Products. Such cooperation and assistance shall be provided in a prompt and timely manner (having regard to the nature of the cooperation or assistance requested) and shall include, without limitation, the following when, if and as requested by Regeneron:
(a)    Aventis shall grant, and does hereby grant, to Regeneron a fully paid-up, royalty-free, exclusive license (which shall include the right to grant sublicenses through multiple tiers) from Aventis under the Aventis Patent Rights, Aventis Know-How, and Aventis’ interest in the Joint Intellectual Property existing at the effective date of termination to Develop, make, have made, use, import, offer to sell and sell the VEGF Products inside and outside of the Field in the Territory.
