Each party will provide the other Party Notice with the name, title, email address, telephone number of their respective Joint Steering Committee Members. The JSC shall meet as needed but not less than on a quarterly basis (or such other frequency as determined by the JSC). The JSC shall be of advisory nature only and shall ensure that Elanco is being kept informed on Tarsus development progress. Tarsus is responsible for and takes final decisions on development and commercialization.

(b) The Joint Steering Committee meetings will be at times agreed by the Parties and will be in such form (e.g. in person, telephone, or video conference) as the members of the Joint Steering Committee agree.

(c) A party may change one or more of its representatives to the Steering Committee at any time. Members of the Joint Steering committee may be represented at any meeting by another member of the Steering committee or by a proxy. Either Party may permit additional employees and consultants to attend and participate in the Joint Steering Committee, subject to the confidentiality provisions of the agreement. Each Party is responsible for travel costs for their representatives associated with attending in person JSC meetings.

(d) The Joint Steering Committee will be responsible for keeping accurate minutes of its deliberations that record decisions and all actions recommended or taken. Within thirty (15) business days of each JSC meeting, the Parties will be provided with draft minutes of such meeting. Minutes will be deemed approved unless a Joint Steering Committee representative of either Party objects to the accuracy of such minutes. In the event that any such objection is not resolved by the Joint Steering Committee such minutes will be amended to reflect the unresolved objection. All records of the Joint Steering Committee will be considered confidential information and available to both Parties.

In addition, Tarsus shall provide to Elanco (i) Tarsus’ most recently available 409A valuation, and (ii) information about all sales and purchases of Tarsus’ Preferred Stock and Common Stock during the respective three-month period.

6.8 Audit. Tarsus shall keep or cause to be kept books of account containing all information that may be necessary for the purpose of calculating amounts payable by Tarsus in connection with this Agreement for a period of three (3) calendar years following the end of the calendar year during which such amounts were payable. Elanco may appoint an independent public accountant (on a non-contingency basis and reasonably acceptable to Tarsus; any “Big 4” accountant shall be deemed acceptable to Tarsus), at Elanco’s expense and subject to such accountant entering into a confidentiality agreement with Tarsus, to inspect such books of account in order to verify the calculation of any amounts payable to Elanco hereunder. Such inspections shall be performed not more frequently than once in any twelve (12) month period and upon reasonable prior written notice, and shall be conducted during regular business hours in such a manner as to not unreasonably interfere with Tarsus’s normal business activities. Elanco’s accountant may only share with Elanco the report containing the summary results of its inspection, but not the books of account reviewed by the accountant during the audit, and such report shall constitute Tarsus’s Confidential Information. If any such inspection reveals that any payment which should have been paid by Tarsus is greater than those which were actually paid by it and such underpayment is not disputed by Tarsus, then Tarsus shall promptly pay the underpaid amount to Elanco. If the undisputed payments which should have been paid by Tarsus are at least [***] percent greater than those which were actually paid by Tarsus, then Tarsus shall also reimburse Elanco for the reasonable out-of-pocket costs of such inspection.

6.9 Taxes. Each Party shall be solely responsible for the payment of all taxes imposed on its share of income arising directly or indirectly from its activities or receipt of payments under this Agreement. To the extent Tarsus is required to deduct and withhold taxes on any payment to Elanco hereunder, it shall deduct such amounts from payments to Elanco and pay the amounts of such taxes to the proper governmental authority in a timely manner and promptly transmit to Elanco an official tax certificate or other evidence of such withholding sufficient to enable Elanco to claim such payment of taxes. Elanco shall provide Tarsus any tax forms that may be reasonably necessary in order for Tarsus not to withhold tax or to withhold tax at a reduced rate under an Applicable Law or bilateral income tax treaty.

6.10 Sales Forecast. Within [***] days after January 1 of each calendar year, Tarsus shall provide Elanco with Tarsus’s projected Net Sales over the next [***] calendar years.

7.1 Prosecution and Maintenance of Licensed Patents.

(a) Elanco shall be solely responsible for prosecution and maintenance of the Licensed Patents including, but not limited to, the filing of patent applications included therein.

Elanco shall consider in good faith the comments of Tarsus with respect to any such applications and prosecutions and maintenance activities.

(b) Elanco may, in its sole discretion, elect to abandon any issued patent or pending patent application included in the Licensed Patents, or not file any patent application with respect thereto in any country. Prior to any such abandonment or decision not to file in any country, Elanco shall give Tarsus at least [***] days’ notice and a reasonable opportunity to take over such maintenance, prosecution or filing. In such event, Tarsus shall have the right, but not the obligation, to commence or continue such maintenance, prosecution or filing under its own control and at its sole expense. Tarsus shall have no further payment obligations (including with respect to royalties and milestone payments) or other obligations to Elanco with respect to any such patents or patent applications or patents issuing from such applications.

7.2 Enforcement of Licensed IP.

(a) During the Royalty Term, each Party shall promptly provide written notice to the other Party of any actual or alleged infringement or misappropriation in the Field by any Third Party of any intellectual property rights included in the Licensed IP of which it becomes aware. Elanco shall have the first right, but not the obligation, to enforce the Licensed IP against any such infringement or misappropriation claim in the Field at its own expense and utilizing counsel of its choice. Elanco shall neither settle nor voluntarily dispose of any action to enforce the Licensed IP in the Field without Tarsus’s written consent. If Elanco desires to voluntarily dispose of any action to enforce the Licensed IP in the Field then Elanco shall notify Tarsus and offer Tarsus the opportunity to assume control of such enforcement action (“Voluntary Disposal Notice”). If Tarsus notifies Elanco of its election to assume control of such enforcement action then Elanco shall take all reasonable actions necessary to allow Tarsus to properly do so. Elanco may voluntarily dispose of such enforcement action if: (i) Tarsus notifies Elanco that it does not desire to assume control of such enforcement action; or (ii) Tarsus does not notify Elanco of any election within [***] days after Elanco provides Voluntary Disposal Notice.

(b) With respect to any potential enforcement under subsection (a) above, if Elanco does not notify Tarsus of its intention to enforce against such alleged infringement or misappropriation within [***] days of the date Elanco becomes aware of such alleged infringement or misappropriation,

or does not commence prosecution of such claim within [***] days after the date Elanco becomes aware of such alleged infringement or misappropriation, then, Tarsus shall have the right, but not the obligation, to prosecute such claim at its own expense and utilizing counsel of its choice.

(c) The enforcing Party shall regularly update the other Party in writing with respect to the status of any such enforcement actions. Any recovery of damages by shall be applied (i) first, in satisfaction of any unreimbursed expenses and legal fees of the enforcing Party, (ii) second, in satisfaction of any unreimbursed expenses and legal fees of the other Party, and (iii) third, if additional recoveries remain after all of the unreimbursed expenses and legal fees are fully paid as set forth in (i) and (ii), the balance remaining with respect to any such recovery shall be retained by (or paid by Elanco to, as the case may be) Tarsus and such amount shall be treated as Net Sales and subject to the payment of royalties pursuant to Section 6.3.

(d) At the request of the Party bringing the action, the other Party shall provide reasonable assistance in connection therewith, including by executing reasonably appropriate documents, cooperating in discovery and joining as a party plaintiff to the action if required to obtain necessary standing.

7.3 Improvements. Elanco shall own any invention conceived by or for Elanco from the use of the Compound or otherwise derived by or for Elanco from the Compound (“Elanco Improvements”). Tarsus shall own any invention conceived by or for Tarsus from the use of the Compound or otherwise derived by or for Tarsus from the Compound (“Tarsus Improvements”). Tarsus hereby grants Elanco an exclusive royalty-free, perpetual license to the Research Inventions and Tarsus Improvements for applications in the Elanco Field.

8. MANUFACTURE AND SUPPLY.

8.1 Initial Supply Terms. Each calendar quarter, Tarsus shall supply Elanco with a written, non-binding forecast showing good faith estimations of its (and its Affiliates’ and sublicensees’) quarterly requirements for the Compound for the following four (4) calendar quarters (the “Forecast”). Elanco shall manufacture (or have manufactured) and supply to Tarsus quantities of the Compound as and when reasonably requested by Tarsus to the extent within the Forecast. Tarsus’s price for all Compounds purchased pursuant to this Section 8.1 shall be the price at which Elanco purchases such Compound plus [***] percent thereof.

8.2 Manufacturing and Supply Agreement. The Parties agree to enter into a good-faith more detailed manufacturing and supply agreement within a reasonable timeframe. The supply agreement should provide for a stated supply price (which price shall represent a small markup over Elanco’s costs).

8.3 Change of chemistry.

(a) Tarsus acknowledges and agrees that Elanco shall be free to use alternate chemistry and improve the Compound in its sole discretion without Tarsus consent.

(b) Elanco shall provide Tarsus with [***] prior notice (the “Compound Change Period”) if Elanco will cease to provide any Compound previously provided to Tarsus pursuant to a chemical change and will supply Tarsus with any quantities of such Compound requested by Tarsus during the Compound Change Period (even if such quantities exceed the amount projected in the Forecast). Elanco shall notify the JSC as soon as it contemplates possibly ceasing to provide a Compound as previously provided to Tarsus because of use of alternative chemistry or other changes to the Compound. The JSC shall discuss such contemplated changes if Tarsus informs Elanco that it reasonably believes such change could have a regulatory impact; provided, however, that Elanco shall have the right to make the final decision regarding such change after discussion by the JSC.

8.4 Have Made Rights. For clarity, Section 2.1 grants Tarsus the right to have a third party make the Compound for Tarsus. Elanco must approve such third party supplier unless: (a) the transfer to the supplier does not qualify as a Sensitive Transfer; or (b) such supplier is credible and reputable. Such approval shall not be unreasonably withheld, conditioned, or delayed. For all purposes of the foregoing, the following entities and their Affiliates shall be deemed credible and reputable (and shall not require Elanco consent): [***] (or any Affiliate of the foregoing), [***].

9. INDEMNIFICATION; INSURANCE.

9.1 Indemnification by Elanco. Elanco shall indemnify, defend and hold harmless Tarsus, its Affiliates, and its and their respective officers, directors, employees, agents, successors and assigns against all third party losses, damages, liabilities, deficiencies, claims, actions, judgments, settlements, interest, awards, penalties, fines, costs or expenses (collectively, “Losses”), resulting from (a) any action instituted against any of them by any Third Party arising out of from Elanco’s breach of any representation, warranty or obligations pursuant to this Agreement, or (b) the gross negligence or willful misconduct of Elanco, except, in each case, to the extent such Losses are Losses for which Tarsus is obligated to indemnify Elanco pursuant to Section 9.2 or to the extent such Losses arise from the breach by Tarsus or its Affiliates of its representations, warranties or obligations under this Agreement or from the failure of any sublicensees to comply with any obligations required of sublicensees under this Agreement.

9.2 Indemnification by Tarsus. Tarsus shall indemnify, defend and hold harmless Elanco, its Affiliates, and its and their respective officers, directors, employees, agents, successors and assigns against all Losses resulting from (a) Tarsus’s breach of any representation, warranty or obligations pursuant to this Agreement, ,(b) the gross negligence or willful misconduct of Tarsus; or (c) the development, making, having made, using, having used, leasing, importing, offering to sell, selling and/or having sold, any Compound or Licensed Product by Tarsus, its Affiliates and sublicensees or the failure of any of them to comply with Applicable Law in connection with any such activities, except, in each case, to the extent Elanco is required to indemnify Tarsus under Section 9.1 for such Losses or to the extent such Losses arise from the breach by Elanco or its Affiliates of its representations, warranties or obligations under this Agreement.

9.3 Indemnification Procedure. The indemnified party shall promptly notify the indemnifying party in writing of any action for which it intends to seek indemnification hereunder and cooperate reasonably with the indemnifying party at the indemnifying party’s sole cost and expense. The indemnifying party shall have the right, within thirty (20) days after being so notified, to assume the defense of any action with counsel of its choice that is reasonably satisfactory to the indemnified party. The indemnifying party shall not settle any action in a manner that adversely affects the rights of any indemnified party without the indemnified party’s prior written consent, which consent shall not be unreasonably withheld or delayed. The indemnified party’s failure to provide prompt notice to the indemnifying party of any action shall not relieve the indemnifying party of its obligations under this Section 9.3 except to the extent that the indemnifying party can demonstrate that it has been materially prejudiced as a result of the failure. Subject to the indemnifying party’s right to control the defense and settlement thereof, the indemnified party may participate in and observe the proceedings at its own cost and expense with counsel of its own choosing. A Party shall not be responsible for the indemnification or defense of the other Party to the extent arising from any negligent or intentional acts by such Party, or the breach by such Party of any representations, obligations or warranty under this Agreement, or any claims compromised or settled without prior written consent.

9.4 Limitation of Liability. Except with respect to a breach of Section 10, or a Party’s liability pursuant to Section 9 or Section 7.2, neither Party shall be liable for special, incidental, consequential, exemplary, punitive, or other indirect or remote damages, or loss of profits, loss of data or loss of use damages arising in any way out of this Agreement or the exercise of its rights hereunder, whether based upon warranty, contract, tort, strict liability or otherwise.

10.1 Non-Disclosure and Non-Use. Each Receiving Party shall:

(a) not disclose any Confidential Information of the Disclosing Party to any Person other than (i) Persons who have a “need to know” such information for purposes of the Receiving Party’s performance or exercise of rights under this Agreement, and (ii) any Affiliates or sublicensees (or potential sublicensees) of the Receiving Party or other Persons working on the Receiving Party’s behalf (including without limitation consultants, contract manufacturers, and independent contractors), provided that any such Person agrees to be bound by terms and conditions no less stringent than those set forth in this Section 10; and

(b) not use any Confidential Information of the Disclosing Party for any purpose other than in connection with performing its obligations or exercising its rights under this Agreement.

(b) No such termination by a Party pursuant to Section 11.2(a) shall be effective prior to the resolution of any dispute with respect to the occurrence of any material breach of or default under this Agreement as to which such Party seeks to exercise such right of termination. If as a result of such dispute resolution process it is determined that a Party’s notice of breach was proper, then such notice shall be deemed to have been effective if the breaching Party fails thereafter to cure such breach in accordance with the determination made in the resolution process within the applicable cure period following such determination. If as a result of such dispute resolution process it is determined that the notice of breach was improper, then no such notice shall be deemed to have been effective and this Agreement shall remain in effect.

Termination or expiration of this Agreement shall not affect or prejudice any right of either Party to receive payments due hereunder or for which the event giving rise to such payment obligation has occurred prior the effectiveness of such termination or expiration or preclude or hinder the terminating Party from also bringing, amending or pursuing an action against the other Party for damages and all other available legal and equitable remedies.

(e) Upon termination of this Agreement by Elanco under Section 4.4 (a) or Section 11.2 (a) Tarsus shall as soon as reasonably practicable provide Elanco with copies of all documented technical and other information Controlled by Tarsus that is both: (i) specific to preclinical documentation and technical information with respect to a Licensed Product; and (ii) which are necessary for the development, manufacture and commercialization of the Licensed Product.

Similarly, no Net Sales, sublicense or milestone in the Field (as such term is defined in the Eye Care and Dermatology License Agreement) shall be deemed Net Sales, a sublicense or a milestone under this Agreement.
