1.9Closing. The closing of the purchase of the Specified Assets by Purchaser (the “Closing”) will take place electronically at 9:00 a.m. (U.S. Eastern Standard Time) on the date that is three Business Days after the satisfaction or waiver of the last to be satisfied or waived of the conditions set forth in Sections 5 and 6 (other than those conditions that by their nature are to be satisfied at the Closing) or at such other time and date as mutually agreed in writing by Seller and Purchaser. For purposes of this Agreement, “Closing Date” means the date as of which the Closing actually takes place.

1.10Later Transferred Contracts. For a period of [***] following the Closing Date, (i) in the event that (A) there are any contracts (other than any Specified Contracts or any contracts that are Excluded Assets) that are exclusively related to or otherwise material to the Specified Product to which Seller is a party which would have been transferred to Purchaser as part of this Agreement but for the fact that such contract was not discovered until after the Closing Date (a “Later Discovered Contract”) or (B) a Consent is or was required to be obtained from a Person in order to permit the sale or transfer to Purchaser of the rights of Seller to any Specified Contract or any Later Discovered Contract and such Consent shall not have been obtained at the Closing (each Later Discovered Contract or each Specified Contract for which consent was required but not obtained, a “Later Transferred Contract”), to the extent permitted under the terms and conditions of such Later Transferred Contract and applicable Legal Requirements, Seller agrees (x) to cooperate in assigning to Purchaser such Later Transferred Contract or the applicable rights or obligations under such Later Transferred Contract at the reasonable request of Purchaser, including using commercially reasonable efforts to obtain any necessary Consent, and (y) enter into a mutually agreeable arrangement to obtain for Purchaser the economic claims, rights and benefits under such Later Transferred Contract with respect to which any Consent has not been obtained in accordance with this Agreement until such time as the Consent is obtained, and (ii) in the event there are any contracts to which Seller is a party but are not Specified Contracts or relate to assets retained by Seller but were transferred or assigned to Purchaser, Purchaser agrees to cooperate in assigning to Seller such contracts or the applicable rights or obligations under such contracts at the reasonable request of Seller. Notwithstanding the foregoing, Seller’s obligations with respect to the BARDA Contract and the attainment of the Novation Agreement are governed by Section 4.5 and not this Section 1.10.

1.11Mixed-Use Contracts. Following the date hereof and continuing until the Closing, Seller shall use its commercially reasonable efforts to identify and partially assign or work with the applicable third parties to otherwise separate or replicate (in whole or in part) the Mixed-

Use Contracts such that Seller will be a party to a separate contract exclusively related to the Specified Assets (any such contract or portion thereof exclusively related to the Specified Assets, a “Transferred Mixed-Use Contract”), in each case on terms and conditions which, in the aggregate, are comparable to those of such Mixed-Use Contract prior to assignment, separation or replication (unless otherwise agreed to by Purchaser, which agreement shall not be unreasonably withheld, conditioned or delayed); provided, however, without limiting Seller’s obligation to make available to Purchaser that portion of the Mixed-Use Contract that relates to the Operation, whether pursuant to this Agreement or the Transition Services Agreement, (x) Seller shall be entitled to reject an assignment, separation or replication of a Mixed-Use Contract in the event that the costs to Seller are materially greater than Seller’s existing costs under the applicable Mixed-Use Contract and (y) in no event shall Seller or any of its Affiliates be required to expend money, incur any liability, commence any litigation or offer or grant any accommodation (financial or otherwise) to any third party to effect any such separation, assignment or entry into a new contract. Purchaser shall assume the obligations under the Transferred Mixed-Use Contract in accordance with Section 1.3(a). Nothing in this Agreement shall require the assignment, separation or replication of any Mixed-Use Contract unless and until any necessary Consents are obtained; provided, that Seller shall use its commercially reasonable efforts to obtain any such necessary Consent (subject to the limitation in clause (y) set forth in the proviso above). No Mixed-Use Contract shall be a Specified Contract under this Agreement, provided, however, that any Transferred Mixed-Use Contract shall be deemed to be a Specified Contract under this Agreement. Seller shall keep Purchaser reasonably informed with respect to its efforts and ability to secure and assign any Transferred Mixed-Use Contract and shall promptly inform Purchaser if Seller is, or is reasonably expected to be unsuccessful in such efforts. In the event Seller, after using commercially reasonable efforts, is not able to enter into any arrangement to partially assign, separate or replicate any Mixed-Use Contracts, Purchaser shall use commercially reasonable efforts to enter into new contracts at Closing to replace any such Mixed-Use Contracts and to the extent Purchaser is unable to enter into any new contract to replace any Mixed-Use Contract, Seller and Purchaser shall reasonably cooperate to enter into a mutually acceptable alternative arrangements to provide that, for a period of up to twelve months following the Closing, Purchaser shall receive the interest in the rights and obligations of Seller under any Mixed-Used Contract to the extent exclusively related to the Specified Assets, including under services provided by Seller under the Transition Services Agreement. Any Mixed-Use Contract that is required for Seller to perform services under the Transitional Services Agreement shall not be assigned, in whole or in part, or terminated with respect to such services until the end of the provision of such services under the Transitional Services Agreement, as applicable.

2.Representations and Warranties of Seller.

(b)Royalty Term. Royalty Payments under Section 4.12(a) shall be payable on a Royalty-Bearing Product-by-Royalty-Bearing Product and country-by-country basis in the U.S. Territory and the Ex-U.S. Territory beginning with the First Sale of a Royalty-Bearing Product in a country (which, for clarity, shall exclude all Excluded U.S. TCs) until the later of: (i) expiration of the last-to-expire Valid Claim of the Specified Patent Rights that claims the manufacture, use, sale, offer for sale or import of such Royalty-Bearing Product in such country and (ii) expiration of all Regulatory Exclusivity for such Royalty-Bearing Product in such country (the “Royalty Term”).

All Royalty Payments shall be made by wire transfer in immediately available funds to a bank and account designated in writing by Seller, unless otherwise specified in writing by Seller.

(d)Records; Audit. Purchaser shall keep, and shall require its Affiliates and Licensees to keep, complete and accurate records pertaining to the sale or other disposition, and the manufacture, of Royalty-Bearing Products (including, without limitation, Excluded U.S. TCs) in sufficient detail to permit Seller to determine or confirm the accuracy of the amounts reported, paid and payable pursuant to the preceding provisions of this Section 4.12, which records shall be kept in the same manner, and shall contain the same level of detail, as the records Purchaser and its Affiliates keep with respect to sale or other disposition, and the manufacture, of other pharmaceutical products sold or disposed of by them, and in any event in such manner and detail as are necessary for financial reporting purposes and the preparation of audited financial statements in accordance with applicable Accounting Standards. Purchaser will keep such books and records for three full Calendar Years following the Calendar Year to which they pertain, or such longer period of time as may be required by Legal Requirements. Upon reasonable prior notice and during regular business hours at such place or places where such records are customarily kept, the foregoing records of Purchaser, its Affiliates and Licensees related to the Royalty-Bearing Products (including, without limitation, the Excluded U.S. TCs) may be inspected on Seller’s behalf by an independent certified public accountant (the “Auditor”) selected by Seller and reasonably acceptable to Purchaser for the sole purpose of verifying for Seller the accuracy of the reports furnished by Purchaser and the Royalty Payments made, or required to be made, to Seller pursuant to this Agreement for a period covering not more than the preceding three full Calendar Years. No Calendar Year shall be subject to audit under this Section 4.12(d) more than once. The Auditor will execute a reasonable written confidentiality agreement with Purchaser and will disclose to Seller only such information as is reasonably necessary to provide Seller with information regarding any actual or potential discrepancies between amounts reported and actually paid and amounts payable under this Agreement. The Auditor will send a copy of the report to Purchaser at the same time it is sent to Seller (the “Auditor’s Report”). The Auditor’s Report sent to both Parties will include the methodology and calculations used to determine the results. In the event that the Auditor’s Report reveals an underpayment by Purchaser, Purchaser shall pay the amount of such underpayment to Seller within 30 days after receipt of the Auditor’s Report. Seller shall bear the full cost of such audit unless such audit reveals an underpayment of more than five percent by Purchaser, in which case Purchaser shall reimburse Seller for the reasonable costs of such audit.

(e)[***]

(f)Allowance for Unreimbursed Development Costs. Notwithstanding anything herein to the contrary, Purchaser may offset against the Royalty Payments due with respect to U.S. Gross Profits under Section 4.12(a) an aggregate amount (the “Maximum Allowance”) equal to the lesser of (i) [***] of the Unreimbursed Development Costs incurred by Purchaser, and (ii) $[***];

provided, however, that: (A) in no event will the Royalty Payments due with respect to U.S. Gross Profits under Section 4.12(a) for any Calendar Quarter be reduced by more than [***] by reason of any such offsets (the “Quarterly Offset Cap”), provided that any portion of the amounts that Purchaser would otherwise have been entitled to offset against Royalty Payments for such Calendar Quarter under this Section 4.12(f) in the absence of the Quarterly Offset Cap shall be carried forward and applied against Royalty Payments due with respect to U.S. Gross Profits under Section 4.12(a) for subsequent Calendar Quarters, subject in each such subsequent Calendar Quarter to the Quarterly Offset Cap, until the earlier of (x) such time as all permissible offsets against Royalty Payments under this Section 4.12(f) are, in the aggregate, equal to the Maximum Allowance and (y) expiration of the Royalty Term in the U.S. Territory; and (B) in no event shall the total aggregate offsets during the Royalty Term in the U.S. Territory exceed the Maximum Allowance. For purposes of this Agreement, “Unreimbursed Development Costs,” subject to the following proviso, shall mean any documented fee or expense paid by Purchaser or any of its Affiliates to a third party after the Closing for research and development of any Royalty-Bearing Product, including clinical studies, reasonably required for the sale of such Royalty-Bearing Product in the Field in or for the U.S. Territory, but specifically excluding any such fee or expense that is reimbursed or otherwise borne by any Governmental Entity or other third party; provided that Purchaser shall have, in advance of incurring any such fee or expense, used its commercially reasonable efforts to seek reimbursement or payment thereof by a Governmental Entity, third party beneficiary or end purchaser of the Royalty-Bearing Product to the extent that such reimbursement or payment would reasonably be expected to be available or obtainable.

(g)Diligence Obligations. Commencing upon the Closing and continuing until the expiration of the last-to-expire Royalty Term for any and all Royalty-Bearing Products, Purchaser shall use Commercially Reasonable Efforts to maintain Regulatory Approval for, and commercialize, the Specified Product in the U.S. Territory; provided, however, that upon and following any Change in Control of Seller, Purchaser shall be required to use only its commercially reasonable efforts (under applicable Delaware law) to maintain Regulatory Approval for, and commercialize, the Specified Product in the U.S. Territory. Purchaser may satisfy this obligation in whole or in part through the activities of its Affiliates and Licensees.

(h)Late Payments. In the event that any Milestone Payment due under Section 4.11 or any Royalty Payment due under this Section 4.12 or portion thereof is not made when due, the amount of such overdue payment shall accrue interest at a rate per annum equal to the prime rate, plus 3%, as published in The Wall Street Journal, Eastern Edition for the period from the due date for payment until the date of actual payment; provided, however, that in no event shall such rate exceed the maximum legal annual interest rate. The payment of such interest shall not limit the Seller from exercising any other rights it may have as a consequence of the lateness of any payment under Section 4.11 or this Section 4.12.

(i)Acknowledgements. It is acknowledged and agreed that (i) except as expressly set forth herein, Purchaser will have the authority and freedom to control the Operation and the manufacturer, sale and distribution of the Royalty-Bearing Products following the Closing in its sole discretion and without limitation under this Agreement, and (ii) Purchaser makes no representations or warranties as to whether or when any Milestone Payment or Royalty Payment will

8.5Indemnification Procedures.

(a)If a Party entitled to indemnification under this Section 8 (an “Indemnified Party”) wishes to assert an indemnification claim against the Party subject to such indemnification obligation under this Section 8 (the “Indemnifying Party”), the Indemnified Party will deliver to the Indemnifying Party, as soon as reasonably practicable, a written notice (a “Claim Notice”) setting forth:

(i)the specific subsection of Section 8.2 or 8.3, as applicable, upon which the Indemnified Party is basing its claim and, if applicable, the representation and warranty or covenant alleged to have been breached by the Indemnifying Party;

(ii)a reasonably detailed description of the facts and circumstances giving rise to the claim; and

(iii)a reasonably detailed description of, and a good faith estimate of the total amount of, the Damages actually incurred or expected to be incurred by the Indemnified Party with respect to such claim;

provided, however, that (A) the failure to deliver a Claim Notice to the Indemnifying Party shall not relieve the Indemnifying Party from any liability that it may have to the Indemnified Party, except to the extent that such failure materially prejudices the Indemnifying Party’s ability to defend the related Matter; and (B) the Indemnified Party will not be permitted to deliver a Claim Notice (and will not be entitled to indemnification pursuant to this Section 8) with respect to breaches or inaccuracies of a representation and warranty unless such Claim Notice is delivered before the Expiration Date or Fundamental Expiration Date applicable to such representation and warranty.

(b)If the Indemnified Party receives notice or otherwise obtains knowledge of any Matter or any threatened Matter that may reasonably be expected to give rise to an indemnification claim against the Indemnifying Party, then the Indemnified Party will deliver to the Indemnifying Party a written notice describing such Matter in reasonable detail as soon as reasonably practicable; provided, however, that the failure to so notify the Indemnifying Party shall

not relieve the Indemnifying Party from any liability that it may have to the Indemnified Party, except to the extent that such failure materially prejudices the Indemnifying Party’s ability to defend the Matter. Within thirty (30) days after delivery of such notification, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of any Matter related to a claim by a third party (a “Third-Party Claim”) (with counsel reasonably satisfactory to the Indemnified Party) seeking (i) solely monetary Damages (it being agreed that a general threat to pursue, or reservation of rights with respect to, equitable remedies will be deemed to be a Third-Party Claim seeking solely monetary Damages), or (ii) Damages (including monetary Damages) where the amount of Damages expected to arise from such Third-Party Claim are, after a reasonable assessment by the Indemnified Party made in good faith, not reasonably anticipated to exceed the maximum amount indemnifiable by the Indemnifying Party in respect of a claim of such nature pursuant to Section 8.4; provided, that prior to the assumption of the defense of any Third-Party Claim, the Indemnifying Party shall provide a written undertaking confirming that, as between the Indemnified Party and the Indemnifying Party, any Damages related to such Third-Party Claim, up to the maximum amount of the Indemnifying Party’s indemnification obligations of the respective maximum amount indemnifiable by Seller in respect of a claim of such nature pursuant to Section 8.4, shall be the sole responsibility of the Indemnifying Party; and provided further, that the Indemnifying Party shall not be entitled to (i) assume the defense, appeal or settlement of any Third-Party Claim if (A) the Third-Party Claim relates to or arises in connection with any criminal proceeding, action, indictment, allegation or investigation, (B) any Third-Party Claim that arises under or in connection with any Specified IP Rights, or (C) the Third-Party Claim seeks any injunction or equitable relief against the Indemnified Party (other than a general threat to pursue, or reservation of rights with respect to, an injunction or other equitable relief); or (ii) maintain control of the defense, appeal or settlement of any Third-Party Claim if the Indemnifying Party has failed or is failing to defend in good faith the Third-Party Claim after written notice of such failure from the Indemnified Party and a reasonable opportunity to cure any such alleged failure. If the Indemnifying Party does not assume control of such defense, the Indemnified Party shall control such defense.

(c)If the Indemnifying Party elects to assume the defense of any Third-Party Claim, then:

(i)the Indemnifying Party will not be required to pay or otherwise indemnify the Indemnified Party against any attorneys’ fees or other expenses incurred on behalf of the Indemnified Party in connection with any such Third-Party Claim following the Indemnifying Party’s election to assume the defense of any such Third-Party Claim other than the reasonable costs of investigation and of assistance as contemplated by this Section 8.5; provided, however, that if, in the opinion of outside counsel to the Indemnified Party, it is advisable for the Indemnified Party to be represented by separate counsel due to actual or potential conflicts of interest, the Indemnified Party shall have the right to employ counsel to represent it and in that event the reasonable fees and expenses of such separate counsel shall be paid by the Indemnifying Party;

(ii)the Indemnified Party and the Indemnifying Party will each make available to the other all books, records and other documents and materials that are under the control of such Party, its Affiliates, advisors and representatives that may be reasonably considered necessary or desirable for the defense of any such Third-Party Claim;

(iii)subject to the other provisions of this Section 8.5(c), the Indemnified Party and the Indemnifying Party will execute such documents and take such other actions as may be reasonably requested by the other for the purpose of facilitating the defense of, or any settlement, compromise or adjustment related to, any such Third-Party Claim;

(iv)the Indemnified Party will otherwise fully cooperate as reasonably requested by the Indemnifying Party in the defense of any such Third-Party Claim; provided, however, that such actions and cooperation by the Indemnified Party under clauses “(ii)” through “(iv)” will not unduly disrupt the operations of the Indemnified Party’s business or cause the Indemnified Party to waive any statutory or common law privileges, breach any confidentiality obligations owed to third parties or otherwise cause any confidential information of the Indemnified Party to become public;

(v)the Indemnified Party will not admit any liability with respect to any such Third-Party Claim without the Indemnifying Party’s prior written consent (such consent not to be unreasonably withheld, conditioned or delayed); and

(vi)the Indemnifying Party will have the exclusive right to settle, adjust or compromise any such Third-Party Claim, on such terms as the Indemnifying Party may consider appropriate, with the consent of the Indemnified Party (which will not be unreasonably withheld, conditioned or delayed); provided, however, that the consent of the Indemnified Party shall not be required with respect to any such settlement, adjustment or compromise if the Indemnifying Party agrees in writing to pay or cause to be paid any amounts payable pursuant to such settlement, adjustment or compromise and such settlement, adjustment or compromise includes no admission of liability by or other obligation on the part of the Indemnified Party and includes a full release of the Indemnified Party with respect to such Third-Party Claim.

If the Indemnifying Party elects not to assume the defense of any Third-Party Claim, then the Indemnified Party will proceed diligently to defend any such Third-Party Claim with the assistance of counsel; provided, however, that the Indemnified Party shall not settle, adjust or compromise any such Third-Party Claim, or admit any liability with respect to any such Third- Party Claim, without the prior written consent of the Indemnifying Party (which will not be unreasonably withheld, conditioned or delayed). The party controlling the defense of any Third-Party Claim shall keep the other party reasonable informed concerning the progress and status of such Third-Party Claim and consider in good faith recommendations made by the other party with respect to the defense of such Third-Party Claim.

8.6Materiality. With respect to any representation or warranty contained in this Agreement or any other Ancillary Agreement that is qualified by materiality, material adverse effect, “Specified Product Material Adverse Effect” or a derivative thereof, such qualification will be ignored and deemed not included in such representation or warranty for the purposes of (i) calculating the amount of Damages indemnifiable under this Section 8 with respect to such breach or inaccuracy and (ii) determining whether there has been a breach or inaccuracy of such representation or warranty for purposes Section 8.

8.7Subrogation. To the extent the Indemnifying Party makes any indemnification payment to the Indemnified Party, the Indemnifying Party will be entitled to exercise, and will be subrogated to, any rights and remedies (including rights of indemnity, rights of contribution and other rights of recovery) that the Indemnified Party or any of the Indemnified Party’s Affiliates may have against any other Person with respect to any Damages, circumstances or Matter to which such indemnification payment is directly or indirectly related. The Indemnified Party will take such actions as the Indemnifying Party may reasonably request for the purpose of enabling the Indemnifying Party to perfect or exercise the Indemnifying Party’s right of subrogation hereunder.

8.8Tax Treatment of Indemnity Payments. The Parties agree to treat any indemnity payment made pursuant to this Section 8 as an adjustment to the Purchase Price for Tax purposes, unless otherwise required by applicable Legal Requirements.

8.9Mitigation of Damages. The Indemnified Party shall use commercially reasonable efforts to mitigate to the extent required by applicable Legal Requirements (including Delaware law) any Damages for which such Indemnified Party seeks indemnification under this Agreement.

8.10Duplication of Recovery. Any Damages will be determined without duplication of recovery due to facts giving rise to such Damages constituting a breach or inaccuracy of more than one representation, warranty, covenant or agreement or that may be recoverable under more than one of the clauses under Section 8.2 or Section 8.3, as applicable.

8.11Damages Offset. The amount of any Damages that are subject to indemnification under this Section 8 shall be calculated net of the amount of any insurance proceeds, indemnification payments or reimbursements actually received by an Indemnified Party from third parties in respect of such Damages (net of any costs or expenses incurred in obtaining such insurance, indemnification or reimbursement, including any deductibles and increases in insurance premiums or retro-premium adjustments resulting from such recovery). If any Indemnified Party receives any such insurance proceeds, indemnification payments or reimbursements from third parties with respect to any Damages for which it has already received an indemnification payment hereunder, it shall pay the Indemnifying Party an amount equal to the portion of the indemnification payment it received from such third party recovery (net of any costs or expenses incurred in obtaining such insurance, indemnification or reimbursement, including any deductibles and increases in insurance premiums or retro-premium adjustments resulting from such recovery).

9.Miscellaneous.

9.1No Other Representations.

It is accordingly agreed that a Party shall be entitled to seek an injunction or injunctions, specific performance or other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement without proof of damages or otherwise in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which it is entitled at law or in equity.

Net Sales with respect to sales for other than monetary consideration on bona fide, arm’s-length terms, or in the case any Royalty-Bearing Product is “bundled” for sale together with one or more other products for a single price or similar transactions, will be computed at the average price of bona fide, arm’s-length sales by all Selling Persons to third parties during the preceding Calendar Quarter period; or, if no bona fide, arm’s-length sale to a third party has yet occurred, at the non-discounted list price for the Royalty-Bearing Product sold directly by Selling Persons to end users. In the event that no list price has been established, the price will be set at the fair market value of such Royalty-Bearing Product.
