If, after the Effective Date of this Agreement, (x) Licensee reasonably determines that, in order to avoid infringement of a Patent not licensed hereunder that covers or claims a given Product (or Compound contained in such Product), or the manufacture, use, sale or other exploitation thereof in a country, Licensee or its Affiliate or sublicensee is required to acquire or license rights under such Patent from a Third Party, (y) Licensee or its Affiliate or sublicensee actually enters into an agreement to acquire or license such Patent rights (such agreement, a “Third Party License Agreement”), and (z) Licensee reasonably determines that Licensee or its Affiliate or sublicensee is required to pay a royalty or sales-based milestone payment to such Third Party under the Third Party License Agreement, then Licensee will have the right to deduct such payments actually paid by Licensee or its Affiliate or sublicensee to such Third Party under the Third Party License Agreement from the Royalties payable under this Agreement. For the avoidance of doubt, any Patent rights that are licensed or acquired by Licensee to exploit any ingredient in a Product other than a Compound shall not be subject to this provision.

(iii)

Limitations. The reductions set forth in this Section 5.04(c) are cumulative and shall apply, in each case, to the maximum extent applicable; provided that in no event shall any Royalty payment due to MSD from Licensee in respect of any given Calendar Quarter be reduced by more than [***] through operation of Section 5.04(c)(i) and Section 5.04(c)(ii).

[***]

5.06

Payments; Payment Exchange Rate and Currency Conversions.

(a)

(b)

Withholdings.

[***]. Licensee will submit to MSD appropriate proof of payment of the withheld Taxes as well as the official receipts and other information received by Licensee and reasonably requested by MSD in order for MSD to obtain a refund for any such Withholding Taxes within a reasonable period of time. In addition, upon written request from MSD, Licensee will provide MSD reasonable information in its possession and will otherwise provide reasonable assistance to MSD in order to allow MSD

Confidential

to obtain the benefit of any present or future treaty against double taxation which may apply to the Agreement Payments. MSD shall provide to Licensee, at the time or times reasonably requested by Licensee or as required by Applicable Law, such properly completed and duly executed documentation (for example, IRS Form W-9 or applicable Form W-8) as will permit payments made under this Agreement to be made without, or at a reduced rate of, Withholding Taxes.

The Parties shall cooperate in accordance with Applicable Law to minimize any Indirect Taxes incurred in connection with this Agreement.

(b)

Expense of Audit. Any audit conducted pursuant to this Section 5.07 shall be at MSD’s expense; provided, that if the audit reveals an underpayment that exceeds the lesser of [***] and [***] of the sums correctly due to MSD, then the costs of the audit will be paid by Licensee (including any fees charged by any Third Party Auditor for the work associated with the audit).

(c)

Underpayments/Overpayments. If the audit indicates that additional Royalties or other amounts were owed during a given period, Licensee will pay such additional amounts within [***] days after the date the Auditor provides the audit results to MSD and Licensee.

(d)

Record-Keeping by Sublicensee. Licensee will include in each Sublicense Agreement a

provision requiring the sublicensee to make reports available to Licensee and to keep and maintain records to the same extent required of Licensee under this Agreement. Licensee will include audit rights in each Sublicense Agreement and exercise their audit rights no less than [***] every [***] years to ensure the accuracy of sublicensee reporting. Licensee will communicate and compensate MSD for any findings with respect to such sublicensee audits.

5.08

Late Payments. Any amount owed by Licensee to MSD under this Agreement that is not paid within the applicable time period set forth herein will accrue interest at a rate equal to [***].

5.09

Licensee Third Party Agreements. For the avoidance of doubt, notwithstanding anything to the contrary herein but subject to Licensee’s right to deduct payments under Section 5.04(c)(ii), Licensee will be solely responsible for (and will reimburse MSD for, to the extent paid or payable by MSD or any of its Affiliates) all costs and payments of any kind (including all upfront fees, annual payments, milestone payments and royalty payments) arising under any agreements between Licensee (or any of its Affiliates) and any Third Party arising in connection with the activities hereunder, including the Development, Manufacture or Commercialization of Compound or Product in the Field in the Territory.

Licensee Patents. As between the Parties, Licensee will have the sole right, but not the obligation, to file, prosecute and maintain Licensee Patents, at its sole discretion and expense.

6.03

Enforcement and Defense of MSD Patents and Improvement Patents. In the event that either Licensee or MSD becomes aware of any alleged or threatened infringement of any issued patent within the MSD Patents or Improvement Patents, or misappropriation of Know-How within the Merck Know-How or the Know-How Improvements, it will promptly notify the other Party in writing to that effect.

A Party disclosing Confidential Information of the other Party to its Agents will ensure that such Agents are bound in writing, prior to disclosure, by confidentiality and non-use obligations no less restrictive than those contained in this Agreement and will be fully liable to the other Party for breach of such confidentiality and non-use obligations of its Agents.

(c)

Additional Permitted Disclosures. Notwithstanding the provisions of Section 7.01(a), the following disclosures of the other Party’s Confidential Information is permitted as follows:

(ii)

a Party may disclose Confidential Information of the other Party to such Party’s attorneys, independent accountants or financial advisors for the sole purpose of enabling such attorneys, independent accountants or financial advisors to provide advice to the receiving Party, on the condition that such attorneys, independent accountants and financial advisors are bound by confidentiality and non-use obligations that substantially are no

Confidential

less stringent than those confidentiality and non-use provisions contained in this Agreement or are otherwise bound by substantially similar confidentiality and non-use obligations under professional codes of conduct or the like;

(iii)

a Party may disclose such Confidential Information as is required to be disclosed by Applicable Law (including rules of any securities exchange); provided that notice is promptly delivered to the other Party in order to provide an opportunity to seek a protective order or other similar order with respect to such Confidential Information and thereafter the receiving Party discloses to the requesting entity only the minimum information required to be disclosed in order to comply with the request, whether or not a protective order or other similar order is obtained by the other Party; and

(iv)

Licensee may disclose Confidential Information of MSD to bona fide potential or actual acquirers of all or substantially all of the business to which this Agreement relates, as may be necessary in connection with their evaluation of such potential or actual acquisition; provided that any such Third Party is bound in writing, prior to disclosure, by confidentiality and non-use obligations no less restrictive than those contained in this Agreement.

7.02

Breach of Confidentiality.

(b)

The Parties acknowledge the interest in publishing the results of research to obtain recognition within the scientific community and to advance the state of scientific knowledge.

If the Parties are unable to agree on commercially reasonable terms for the AT- 527/511 Combination Grantback License within [***] days after MSD gives notice to Licensee of its election to exercise its rights under Section 10.05(a)(2), then Licensee, its Affiliates and its sublicensees and subcontractors will wind-down, at Licensee’s sole expense and in accordance with accepted pharmaceutical industry norms, ethical and medical practices, and all Applicable Law and Regulatory Authority requirements, any Clinical Trials related to the AT-527/511 Combination Products in the AT-527/511 Combination Grantback Field that are being conducted under Licensee’s (or its Affiliate’s or sublicensee’s or subcontractor’s) IND for such products and are ongoing as of the date this Agreement is terminated, including, if not adverse to patient safety, completing treatment for the patients then-enrolled and who have commenced dosing in such Clinical Trials.
