[***]

“Veterinary Product” means a product that is covered by Patent Rights which is used for the care, treatment, breeding or use of livestock or companion animals.

“Third Party” means any person, corporation, partnership, association, consortium or business, legal or governmental entity other than Penn, mRNA RiboTherapeutics, Company or any of their respective affiliates.

1.3 Reservation of Rights by Penn. Penn reserves the right to use, and to permit other non-commercial entities to use, the Patent Rights for educational and non-commercial research purposes.

1.4 U.S. Government Rights. The Parties acknowledge that the United States government retains rights in intellectual property funded under any grant or similar contract with a Federal agency. The License is expressly subject to all applicable United States government rights, including, but not limited to, any applicable requirement that products, which result from such intellectual property and are sold in the United States, must be substantially manufactured in the United States. To the extent any such U.S. manufacturing requirements apply, mRNA RiboTherapeutics shall, upon request of Company, use commercially reasonable efforts to cause Penn to seek a waiver from the United States government for Company in respect of such U.S. manufacturing requirements.

1.5 Sublicense Conditions. Company’s right to extend any or all of the rights granted to Company by mRNA RiboTherapeutics via a sublicense to affiliates or Third Parties is subject to each of the following conditions:

1.5.1 Company will have the right to grant further sublicenses to its affiliates and to Third Parties (“sub-sublicensees”) that permit multiple levels of sublicensing, including in Third Party sub-sublicenses that permit further levels of sublicensing (e.g., to “sub-sub-sublicensees”). In each further sub-sublicense agreement to an affiliate or Third Party, Company will require the sub-sublicensee to comply with terms and conditions that are consistent with this Agreement, and in each agreement for further sublicensing (e.g., by a sub-sublicensee of Company to a sub-sub-sublicensee), the party granting the further sublicense will require the party receiving the further sublicense to comply with terms and conditions that are consistent with its sub-sublicense agreement from Company. Except when used to clarify the meaning of the different terms in this Section 1.5.1, the term sublicense in this Agreement includes any permitted sub-sublicense, sub-sub-sublicense, etc. and the term sublicensee includes any permitted sub-sublicensee, sub-sub-sublicensee, etc.

1.5.2 Within [***] days after Company enters into a sublicense agreement, Company will deliver to mRNA RiboTherapeutics a complete and accurate copy of the entire sublicense agreement written in the English language, provided that Company will have the right to redact the terms and conditions of such sublicense agreement that are not necessary for mRNA RiboTherapeutics to confirm compliance with all terms and conditions required under this Sublicense, including Section 1.5 hereof. mRNA RiboTherapeutics’ receipt of the sublicense agreement will not constitute a waiver of any right or obligation of mRNA RiboTherapeutics or of Company under this Agreement.

1.5.3 In the event that Company causes or experiences a Trigger Event (as defined in Section 6.4), to the extent permissible by law, all payments due to Company from its direct sublicensees pursuant to a sublicense to this Agreement that are payable by Company to Cellscript hereunder, including milestone payments and royalty payments, will, upon notice from mRNA RiboTherapeutics to such sublicensees, become payable directly to mRNA RiboTherapeutics for the account of Company. Upon receipt of any such funds, mRNA RiboTherapeutics will remit to Penn the amounts owed to Penn and will remit to Company the amount (if any) by which such payments from such sublicensees exceed the amounts owed by Company to mRNA RiboTherapeutics. Still further, in the event that mRNA RiboTherapeutics causes or experiences a trigger event according to the terms of the Penn License Agreement, Company agrees that, upon notification from Penn, Company will remit to Penn all amounts payable by Company to mRNA RiboTherapeutics under this Agreement (including but not limited to all milestone payments and royalty payments) for the account of mRNA RiboTherapeutics.

1.5.4 Company’s execution of a sublicense agreement will not relieve Company of any of its obligations under this Agreement. Company is primarily liable to mRNA RiboTherapeutics for any act or omission of a sublicensee that would be a breach of this Agreement if performed or omitted by Company, and Company will be deemed to be in breach of this Agreement as a result of such act or omission. Upon learning of any such breach of this Agreement due to an act or omission of a sublicensee of Company, Company will immediately take appropriate actions to stop such act or omission, including termination of the sublicense by Company. Provided that Company takes such appropriate actions and stops such act or omission, a breach by said sublicensee shall not be considered a breach by Company that will be considered a cause for termination of this Agreement under Section 6.3.

1.5.5 A sublicense granted by the Company or a further sublicensee thereof will not be assignable or transferable by said sublicensee or further sublicensee thereof without the prior written consent of mRNA RiboTherapeutics, except to an affiliate of the sublicensee of Company or an affiliate of said further sublicensee thereof, or to a Third Party company that:    (i) can demonstrate based on reliable financial information that it has all technical knowledge, capabilities and/or financial resources needed to perform in all respects in the place and stead of said sublicensee or further sublicensee thereof; (ii) agrees to assume all duties and responsibilities under the sublicense; (iii) warrants that it will invest an amount of money that Company agrees is sufficient to develop and/or commercialize the sublicensed Licensed Product(s); (iv) purchases more than fifty percent (50%) of all of the sublicensee’s or the further sublicensee’s shares or assets to which the sublicense pertains; and (v) agrees in writing to be bound by all of the terms and conditions of the sublicense and a copy of such written undertaking is promptly provided to Company, which will provide a copy to mRNA RiboTherapeutics, which, in turn, will provide a copy to Penn as required in the Penn License Agreement.

1.6 No License by Implication. Nothing in this Agreement confers by estoppel implication or otherwise, any license or rights under any Penn patent other than rights under a patent included in the Patent Rights, regardless whether such patents are dominant or subordinate to the Patent Rights.

1.7 Relation of this Agreement to the Sublicense Agreement from Cellscript. Concurrent with the execution of this Agreement, Company is entering into a separate sublicense agreement with Cellscript (the “Sublicense Agreement from Cellscript”), pursuant to which Cellscript is granting Company a sublicense under Patent Rights with respect to certain fields of use that are different from and are not included within the scope of the Sublicense granted to Company in this Agreement.

3.5.2 The term “Quarter” means each three-month period beginning on the first day of January, April, July or October.

3.5.3 The term “Net Sales” means the consideration received or expected from, or the fair market value attributable to, each Sale, less Qualifying Costs that are directly attributable to a Sale, specifically identified on an invoice or other documentation and actually borne by Company or its Affiliates or Third Party sublicensees. For purposes of determining Net Sales, the words “fair market value” mean the cash consideration that Company or its Affiliates or Third Party sublicensees would realize from an unrelated buyer in an arm’s length sale of an identical item sold in the same quantity and at the time and place of the transaction.

12.4 Other Provisions. Company will not settle or compromise any Claim giving rise to Penn Liabilities in any manner that imposes any restrictions or obligations on Penn or grants any rights to the Patent Rights or the Licensed Products without Penn’s prior written consent.

The indemnification rights of the Penn Indemnified Parties under this Article 12 are in addition to all other rights that a Penn Indemnified Party may have at law, in equity or otherwise.

(i) inform the indemnifying Party in writing of a Claim as soon as reasonably practicable after such Indemnified Party receives notice of such Claim;

(ii) permit the indemnifying Party to assume direction and control of the defense of the Claim (including the sole right to settle such Claim at the sole discretion of the indemnifying Party, provided that (a) such settlement or compromise does not admit any fault or negligence on the part of the Indemnified Party, or impose any obligation on, or otherwise materially adversely affect, the Indemnified Party or other Party and (b) the indemnifying Party first obtains the written consent of the Indemnified Party with respect to such settlement, which consent will not be unreasonably withheld);

(iii) cooperate as reasonably requested (at the expense of the indemnifying Party) in the defense of the Claim; and

The required minimum amounts of insurance or self-insurance do not constitute a limitation on Company’s liability or indemnification obligations to Penn or mRNA RiboTherapeutics under this Agreement.

The term “including” as used herein shall mean including, without limiting the generality of any description preceding such term. The language of this Agreement shall be deemed to be the language mutually chosen by the Parties and no rule of strict construction shall be applied against either Party hereto. The Parties acknowledge and agree that new products and uses for products that are covered by Patent rights may be developed based on new advances in scientific knowledge. As such, the Parties’ agree that, if Company is of the opinion that such advances have resulted in changes which warrant interpretation of whether such new products or uses are included within the Sublicensed Fields of Use granted to Company herein, the Parties agree to discuss and negotiate in good faith the need for an amendment or clarification of the meaning of the rights or Fields of Use granted to Company in Section 1.1 of this Agreement in order to try to find a solution that is agreeable to the Parties. Then, if the Parties have not agreed on the necessity or the wording of such amendment within [***] days after beginning good faith discussions, the Parties agree that, either both Parties will jointly agree on and appoint one independent Third Party, or each of the Parties will appoint one independent Third Party and those Third Parties will appoint one additional independent Third Party (all of which Third Parties will be qualified and skilled in the scientific field and have knowledge of law related to patents and licenses) to decide whether such amendment is required to properly reflect this intention. If the appointed independent Third Party or Third Parties decide(s) that said amendment is required, the Parties hereby agree to so amend this Agreement accordingly. If the appointed independent Third Party or Third Parties decide(s) that said amendment is not required, there is no obligation on either Party to amend this Agreement. The costs of the appointed independent Third Party or Third Parties will be borne by the Party whose view has not been confirmed by such Third Party(ies).
