ARTICLE 10. ADDITIONAL COVENANTS

10.1Further Assurances.

(a)The Parties shall cooperate reasonably with each other in connection with any steps required to be taken as part of their respective obligations under this Agreement, including any notifications or filings required to be made to the FDA in connection with the transfer of the Purchased Assets, and shall (a) furnish upon request to each other such information, (b) execute and deliver to each other such other documents, and (c) do such other acts and things, all as the other Party may reasonably request for the purpose of carrying out the intent of this Agreement and the transactions contemplated by this Agreement, including the use by Merck, its Affiliates and/or their respective successors and assigns of the Priority Review Voucher in accordance with its terms and applicable Legal Requirements.

Each Party acknowledges that the other Party, or the other Party’s parent entity, as a publicly traded company, is legally obligated to make timely disclosures of material events relating to its business. The Parties acknowledge that either or both Parties may be obligated to file a copy of this Agreement with the United States Securities and Exchange

Commission (the “SEC”). Without limiting the foregoing, any Party so obligated shall provide the other

Party with a reasonable opportunity to review, comment and request confidential treatment of this

Agreement pursuant to applicable rules under the Securities Exchange Act of 1934, as amended, and the Freedom of Information Act and the rules promulgated thereunder to permit the filing of a redacted exhibit. The Party so obligated shall (a) give due consideration to the other Party’s request, and (b) use reasonable efforts to incorporate any comments provided by the other Party, limit such disclosure or obtain such confidential treatment or permission to redact such exhibit, provided that there is no assurance that such request will be granted by the SEC and the SEC may require filing of the Agreement in full.

ARTICLE 11. GENERAL PROVISIONS

11.1Survival. Except as expressly set forth herein, the representations and warranties contained in this Agreement, and liability for the breach thereof, shall survive the Closing Date and shall remain in full force and effect for a period of three (3) years following the Closing Date; provided, however, that the representations and warranties contained in Sections4.1, 4.2, 4.6, 4.9, 4.11, 4.12and4.13 hereof, and all covenants and obligations contained herein, shall, in each case, survive the Closing Date and remain in full force and effect until the expiration of the applicable statute of limitations.

For clarity, the obligation to withhold shall not be deemed “payable” by a Party or its Affiliates pursuant to the foregoing sentence, but shall be considered an obligation of the Party on whose behalf the withholding is paid to the Governmental Entity.

11.3Priority Review Fee. The priority review fee described in Section 524(c) of the FDC Act (21 U.S.C § 360n) (the “Priority Review Fee”) and all other user fees under the FDC Act applicable to human drug application for which the Priority ReviewVoucher is redeemed, following the Closing shall be borne exclusively by Merck, its Affiliates or any transferee of the Priority Review Voucher.

11.5Construction.

i.The Parties agree that any rule of construction to the effect that ambiguities are to be resolved against the drafting Party shall not be applied in the construction or interpretation of this Agreement.

ii.As used in this Agreement, the words “include” and “including,” and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words “without limitation.”

iii.Except as otherwise indicated, all references in this Agreement to “Articles” and “Sections” are intended to refer to Articles and Sections of this Agreement.

11.6Counterparts. This Agreement may be executed in two or more counterparts, all of which shall be considered one and the same instrument, and shall become effective when one or more counterparts have been signed by each of the Parties hereto and delivered to the other Party hereto, it being understood that all Parties hereto need not sign the same counterpart. The exchange of a fully executed Agreement (in counterparts or otherwise) by electronic transmission or facsimile shall be sufficient to bind the Parties hereto to the terms and conditions of this Agreement. 








11.7Entire Agreement. This Agreement, including all exhibits and schedules attached hereto, set forth the entire understanding of the Parties relating to the purchase of the Purchased Assets and supersede all prior agreements and understandings among or between the Parties relating to thereto. For clarity, no provision in this Agreement shall supersede any provision of the License and Collaboration Agreement and shall not release Merck, Lumos or BioProtection Systems Corporation of any of their respective obligations or liabilities pursuant to the License and Collaboration Agreement. In the event of any inconsistencies between the terms of this Agreement and the License and Collaboration Agreement, the terms of the License and Collaboration Agreement will control. For clarity, the Parties agreement that all of the payment obligations of Lumos or BioProtection Systems Corporation to Merck under Section 5.3.1 of the License and Collaboration Agreement shall be deemed to be satisfied upon Closing pursuant to Section 2.2 shall not be deemed an inconsistency between the terms of this Agreement and the License and Collaboration Agreement.

11.8Assignment. No Party will have the right to assign this Agreement, in whole or in part, by operation of law or otherwise, without the other Party’s express prior written consent. Any attempt to assign this Agreement without such consent, will be null and void. Notwithstanding the foregoing, any Party may assign this Agreement, in whole or in part, without the consent of the other Party: (a) to a Third Party that succeeds to all or substantially all of its assets or business related to this Agreement (whether by sale, merger, operation of law or otherwise); or (b) to an Affiliate of such Party. Notwithstanding the foregoing, Merck may assign this Agreement, in whole or in part, without Lumos’s consent, to any purchaser, transferee, or assignee of any of the Purchased Assets. For the avoidance of doubt, no assignment made pursuant to this Section 11.8 shall relieve the assigning Party of any of its obligations under this Agreement. Subject to the foregoing, this Agreement will bind and inure to the benefit of each Party’s successors and permitted assigns.

11.9Severability. If any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement shall continue in full force and effect and shall be interpreted so as to reasonably effect the intent of the Parties hereto. The Parties hereto shall use commercially reasonable efforts to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that shall achieve, to the extent possible, the economic, business and other purposes of such voided or unenforceable provision.

11.10 Remedies Cumulative. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a Party hereto shall be deemed cumulative with and not exclusive of any other remedy conferred hereby or by law or equity upon such Party, and the exercise by a Party hereto of any one remedy shall not preclude the exercise of any other remedy and nothing in this Agreement shall be deemed a waiver by any Party of any right to specific performance or injunctive relief.

11.11 Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of law. The Parties irrevocably and unconditionally submit to the exclusive jurisdiction of the United States District Court in Wilmington, Delaware (or if such court does not have subject matter jurisdiction, a State Court of the State of Delaware located in Wilmington, Delaware) solely and specifically for the purposes of any action or proceeding arising out of or in connection with this Agreement. 








11.12 Amendment; Extension; Waiver.

Any agreement on the part of a Party hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such Party. Without limiting the generality or effect of the preceding sentence, no delay in exercising any right under this Agreement shall constitute a waiver of such right, and no waiver of any breach or default shall be deemed a waiver of any other breach or default of the same or any other provision in this Agreement.

11.13 Representation By Counsel; Interpretation. Lumos and Merck each acknowledge that it has been represented by its own legal counsel in connection with this Agreement and the transactions contemplated by this Agreement. Accordingly, any rule of law, or any legal decision that would require interpretation of any claimed ambiguities in this Agreement against the Party that drafted it, has no application and is expressly waived.

11.14 Expenses. Whether or not the purchase and sale of the Purchased Assets and the other transactions contemplated by this Agreement are consummated, and expect as otherwise set forth in this Agreement, each of the Parties shall bear its own fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby.

Press Release

Lumos Pharma Announces Sale of Priority Review Voucher

AUSTIN, TX, July 27, 2020 (GLOBE NEWSWIRE) – Lumos Pharma, Inc. (NASDAQ:LUMO), a clinical-stage biopharmaceutical company focused on therapeutics for rare diseases, today announced that it has entered into a definitive agreement to sell its Priority Review Voucher (PRV) to Merck, known as MSD outside the United States and Canada.

The PRV was granted in conjunction with the approval by the U.S. Food and Drug Administration (FDA) of ERVEBO®, a vaccine developed by the Company’s licensee, Merck, for the prevention of the Zaire Ebola virus disease. Under the terms of the original license agreement Lumos Pharma is entitled to retain 60% of the value of the PRV. Based upon an agreed valuation of $100 million Merck will pay Lumos $60 million. The transaction remains subject to customary closing conditions, including anti-trust review.

“We are pleased to announce the sale of the PRV, which will provide an important source of non-dilutive capital to fund additional investment in our pipeline and the evaluation of other assets for potential acquisitions or partnerships. These efforts will be critical to our growth over the coming year, and we are committed to our strategic priority of becoming leaders in the rare and ultra-rare disease space,” said Rick Hawkins, Chairman, CEO and President. “Additionally, we are looking forward to initiating our Phase 2b trial of our lead candidate LUM-201 in patients with Pediatric Growth Hormone Deficiency, or PGHD, prior to the end of 2020. We believe we have the opportunity to greatly improve the standard of care for patients impacted by this disease. If approved, LUM-201 would provide an orally administered alternative to daily injections that current PGHD patients endure for many years of treatment.”

Jefferies & Co. acted as exclusive financial advisor to Lumos Pharma, Inc. on this transaction.

Financial Guidance Update Related to PRV Sale

The total valuation of the PRV in the transaction was $100 million, Lumos Pharma will receive approximately $60 million which represents the Company’s 60% interest in the total value of the PRV. The $60 million will be received in two noncontingent payments, $34 million in 2020 and $26 million in the first quarter of 2021. The non-dilutive funds from this transaction will provide additional capital to support the expansion of its pipeline through the in-licensing or acquisition of another novel therapeutic candidate for those suffering from rare diseases. These funds are in addition to the Company’s cash position as of March 31, 2020 which was anticipated to be sufficient to support the Company’s current operations through the Phase 2b clinical trial read-out.
