- 13 -

2.5.1 Obligations on VYNE. During the Term, VYNE hereby covenants that it shall not, directly or indirectly, either by itself or with or through any of its Affiliates or any Third Party, Develop, Manufacture, or Commercialize any Competing BETi Product in the Field in the Territory.
2.5.2 Acquisition of Competing Product. If a Third Party becomes an Affiliate of VYNE after the Effective Date through merger, acquisition, consolidation or other similar transaction, and as of the closing date of such transaction, such Third Party is engaged in the Development, Manufacture or Commercialization of any product containing or comprising a BETi that, if conducted by VYNE, would cause VYNE to be in breach of its exclusivity obligations set forth in Section 2.5 (a “Competing Program”), then:
(a)if such transaction results in a Change of Control of VYNE or any Affiliate that controls VYNE, then such new Affiliate may continue such Competing Program and such continuation will not constitute a breach of VYNE’s exclusivity obligations set forth above; provided that (i) such new Affiliate conducts such Competing Program independently of the activities of this Agreement, does not use any Tay Technology in the conduct of such Competing Program and does not have access to any non-public Tay Technology or Confidential Information of Tay; (ii) VYNE shall implement and maintain reasonable measures to segregate the Tay Technology in order to comply with this clause (including firewalls and screens (whether technical or physical) between VYNE and the Affiliate), and (iii) at Tay’s request, VYNE shall promptly provide Tay with reasonable details of such measures; and
(b)if such transaction does not result in a Change of Control of VYNE, then VYNE and its new Affiliate will have nine (9) months from the closing date of such transaction to either wind down and terminate such Competing Program or complete the Divestiture of such Competing Program, and VYNE’s new Affiliate’s conduct of such Competing Program during such nine (9)-month period will not be deemed to be a breach of VYNE’s exclusivity obligations set forth above; provided that (i) such new Affiliate conducts such Competing Program during such nine (9)-month period independently of the activities of this Agreement, does not use any Tay Technology in the conduct of such Competing Program and does not have access to any non-public Tay Technology or Confidential Information of Tay; (ii) VYNE shall implement and maintain reasonable measures to segregate the Tay Technology in order to comply with this clause (including firewalls and screens (whether technical or physical) between VYNE and the Affiliate) and (iii) at Tay’s request, VYNE shall promptly provide Tay with reasonable details of such measures. For the purposes of this Section 2.5.2, “Divestiture” means the sale and transfer of the Competing Program to a Third Party without VYNE (or its Affiliate) receiving a continuing share of profit, royalty payment, or other economic interest in the success of such Competing Program or being actively involved in, or having any decision-making authority with respect to, the development, manufacture or commercialization of products under such Competing Program.
2.6 Technology Transfer and Assistance. As soon as reasonably practicable following the Effective Date, Tay shall, and shall cause its Affiliates to, without additional compensation, disclose and make available to VYNE (which obligation may include granting

The Parties shall reasonably cooperate to provide a smooth and prompt provision of all such Know-How. At VYNE’s request, Tay shall reasonably assist VYNE and its designees in the use and understanding of the Tay Know-How and shall promptly provide reasonable assistance and cooperation, and make its personnel reasonably available to VYNE and its designees, as necessary or reasonably useful for VYNE to Exploit the Compounds and Products; provided that, unless otherwise agreed, VYNE shall reimburse Tay for all documented (a) external costs on a pass-through basis and (b) internal expenses at an hourly rate per FTE based on the relevant FTE’s standard, then-current industry standard rate per annum, in each case of (a) and (b), that are reasonably incurred by Tay in providing such assistance. As used herein, “FTE” means a full-time equivalent person year (consisting of a total of one thousand eight hundred twenty (1,820) hours per year) of activities undertaken by Tay.
2.7 Non-Compete. During the Term, Tay hereby covenants that it shall not, directly or indirectly, either by itself or with or through any of its Affiliates or any Third Party, Develop, Manufacture, or Commercialize any of the BETi compounds listed in Exhibit 2.7 (the “Retained Compounds”) in the Field in the Territory.

In partial consideration of the rights granted by Tay to VYNE under this Agreement and subject to the terms and conditions set forth in the remainder of this Section 8.2, on a Product-by-Product basis, VYNE shall pay to Tay the non-refundable, non-creditable milestone payment set forth in the table below within [***] following the first achievement of the corresponding milestone event by a Product by or on behalf of VYNE or its Affiliates or Sublicensees:

- 20 -

1 | [***] | [***]
2 | [***] | [***]
3 | [***] | [***]
4 | [***] | [***]
5 | [***] | [***]
6 | [***] | [***]
7 | [***] | [***]
8 | [***] | [***]
9 | [***] | [***]
10 | [***] | [***]
11 | [***] | [***]

For clarity: (i) there is no limit on the number of Products for which the above Milestone Payments Amounts may become due; (ii) because the final formulation and dosage strength of a Product is not determined until Phase 3, milestones 1, 2 and 3 will not be due more than once in respect of different formulations and dosages of a Product that is being Developed for the same indication and route of administration; (iii) milestones 9, 10 and 11 above will be due in respect of both a second Indication and a third Indication of a Product; and (iv) in respect of any particular Product, the same milestone event may occur (and the corresponding Milestone Payment Amount become due) for such Product as both for topical administration and for oral administration (and for any other administration), as more particularly set forth in Section 8.2.2.
8.2.2 New Administration. [***].
8.2.3 Skipped Milestones. [***].
8.3 Royalties.

- 21 -

8.3.1 Royalty Rates. As further consideration for the rights granted to VYNE under this Agreement, subject to the remainder of this Section 8.3, during the Royalty Term, VYNE shall make quarterly, non-refundable, except as set forth in Section 8.8, non-creditable royalty payments to Tay on the annual Net Sales of all Products sold by or on behalf of VYNE, its Affiliates or Sublicensees in the Territory at the applicable rate set forth in the table below. Solely for the purpose of calculating the applicable royalty rate set forth in the table below, “Products” shall be deemed to include both Products as defined herein and “Products” as defined in the Topical License Agreement, which are subject to royalties thereunder at the same tiered royalty rates. By way of example only, if in a given Calendar Year, there are aggregate Net Sales of Products (as defined hereunder) of [***] and aggregate Net Sales of Products (as defined in the Topical License Agreement) of [***], then the royalty rate of [***] shall attach to the portion of such combined Net Sales under [***] and the royalty rate of [***] shall attach to the portion of such combined Net Sales greater than [***]. For clarity, no royalties shall be payable by VYNE hereunder on Net Sales of Products (as defined in the Topical License Agreement), and payment of such royalties is governed solely by the Topical License Agreement.

Annual Net Sales in the Territory of Products in a Calendar Year | Royalty Rate
[***] | [***]
[***] | [***]
[***] | 10%

In the event that a permitted reduction under Section 8.3.3(a) and/or Section 8.3.3(b) applies, then the applicable royalty rate(s) for the portion of the Net Sales subject to the reduction shall be determined based on the overall proportion of combined Net Sales of Products in each royalty tier above during the applicable Calendar Year.
[***]
8.3.2 Royalty Term. Royalties shall be paid on a Product-by-Product and Country-by-Country basis in the Territory from the First Commercial Sale of such Product in a Country by or on behalf of VYNE, its Affiliates, or Sublicensees, until the expiration of the Royalty Term for such Product in such Country.
8.3.3 Permitted Reductions.
(a)Generic Competition. If, in a Country within the Territory during the Royalty Term for a Product, sales of all Generic Products to such Product in such Country in

- 22 -

a Calendar Quarter have a market share of [***] in such country, then the royalty rate payable by VYNE to Tay with respect to Net Sales of the Product in such Country for such Calendar Quarter shall be reduced by [***] of the otherwise applicable rate. If, in a Country within the Territory during the Royalty Term for a Product, sales of all Generic Products to such Product in such Country in a Calendar Quarter exceed [***] of the unit volume of all sales of such Product plus the unit volume of all sales of such Generic Products to such Product in such country (such percentage being the “Relevant Calendar Quarter Percentage”), then the royalty rate payable by VYNE to Tay with respect to Net Sales of the Product in such Country for such Calendar Quarter shall be reduced by a percentage equal to the Relevant Calendar Quarter Percentage, subject always to a maximum reduction of [***] of the otherwise applicable rate. All such determinations of the unit volume of sales shall be based upon a mutually acceptable calculation method using market share data provided by a reputable and mutually agreed upon provider, such as IQVIA.
(b)Third Party License. To the extent VYNE or its Affiliate obtains a right or license under Patents owned by a Third Party and such right or license is necessary to practice the rights purported to be granted to VYNE by Tay under issued Tay Patents in such Country (a “Third Party License”), the royalties payable by VYNE to Tay shall be [***].
(c)Floor. Notwithstanding the foregoing provisions of this Section 8.3.3, in no circumstances will the royalties payable to Tay under this Section 8.3 in any Calendar Quarter be reduced, as a result of this Section 8.3.3, below [***]. VYNE may carry forward to subsequent Calendar Quarters any deductions that it was not able to deduct as a result of the foregoing provision.
8.4 Royalty Payments and Reports. VYNE shall calculate all amounts payable to Tay pursuant to Section 8.3 at the end of each Calendar Quarter, which amounts shall be converted to Dollars, in accordance with Section 8.5. VYNE shall pay to Tay the royalty amounts due with respect to a given Calendar Quarter within sixty (60) days after the end of each Calendar Quarter. Each payment of royalties due to Tay shall be accompanied by a report setting forth the Net Sales of the Products by VYNE and its Affiliates and Sublicensees in the Territory in sufficient detail to permit confirmation of the accuracy of the royalty payment made.
8.5 Mode of Payment. All payments to Tay under this Agreement shall be made by deposit of Dollars in the requisite amount to such bank account as Tay may from time to time designate by written notice to VYNE. For the purpose of calculating any sums due under, or otherwise reimbursable pursuant to, this Agreement (including the calculation of Net Sales expressed in currencies other than Dollars), a Party shall convert any amount expressed in a foreign currency into Dollar equivalents using its, its Affiliate’s, or Sublicensee’s standard conversion methodology consistent with Accounting Standards.
8.6 Taxes.

- 23 -

8.6.1 Taxes on Income. Each Party shall be solely responsible for the payment of all taxes imposed on its share of income arising directly or indirectly from the activities of the Parties under this Agreement.
8.6.2 Withholding Amounts. If any sum due to be paid to Tay under this Agreement is subject to any withholding or similar tax, the Parties shall use their commercially reasonable efforts to do all such acts and to sign all such documents as will enable them to take advantage of any applicable double taxation agreement or treaty. Any tax paid or required to be withheld by VYNE for the benefit of Tay on account of any payments to Tay under this Agreement will be deducted from the amount of royalties or other payments otherwise due. VYNE will secure and send to Tay proof of any such taxes withheld and paid by VYNE for the benefit of Tay. If withholding or similar taxes are paid to a government authority, each Party shall provide the other such assistance as is reasonably required to obtain a refund of the withheld or similar taxes, or to obtain a credit with respect to such taxes paid.
8.6.3 Tax Changing Decision. Notwithstanding the foregoing, to the extent VYNE or its Affiliates (a) assigns or otherwise transfers this Agreement or its obligations hereunder to an Affiliate or Third Party, (b) changes its location of incorporation from the United States to another location, (c) makes payments from an entity, or payments are deemed to be made from an entity, other than the United States entity originally entering into this Agreement, or
(d) fails to comply with Applicable Laws or filing or record retention requirements to enjoy the benefit regarding withholding taxes under the Applicable Laws, in each case that results in a tax being required to be withheld under Applicable Laws that would not have been required to be withheld if such action had not been taken (each, a “Tax Changing Decision”) such that as a result of a Tax Changing Decision, VYNE is required by Applicable Laws to deduct or withhold taxes directly from any amount paid to Tay, then (i) notwithstanding anything to the contrary in this Agreement, VYNE shall increase the amount paid to Tay by the required amount such that the net amount actually received by Tay after such deduction or withholding equals the full amount originally invoiced or stated by Tay to be payable and (ii) VYNE shall timely pay the applicable taxes to the relevant governmental authority in accordance with Applicable Laws.
8.7 Interest on Late Payments. If any undisputed payment due to either Party under this Agreement is not paid when due, then such paying Party shall pay interest thereon (before and after any judgment, but excluding the period during which termination is tolled pursuant to Section 13.3) at an annual rate (but with interest accruing on a daily basis) equal to LIBOR (or other such short term inter-bank interest rate as deemed suitable by the Parties), such interest to run from the date on which payment of such sum became due until payment thereof in full together with such interest.
8.8 Audit. VYNE shall keep, and shall require its Affiliates and Sublicensees to keep, complete and accurate records and books of account (in an electronic format) pertaining to the sale or other disposition of Products in sufficient detail and containing all data necessary to permit Tay to confirm the accuracy of any payments due hereunder. VYNE shall keep such books and records necessary to permit Tay to conduct an audit under this section for a minimum of six (6) years following the Calendar Year to which they pertain, or such longer period of time as may be

- 24 -

required by Applicable Law. Upon reasonable prior notice and during regular business hours at such place or places where such records are customarily kept, such records may be inspected on Tay’s behalf by an independent certified public accountant (the “Auditor”) selected by Tay and reasonably acceptable to VYNE for the sole purpose of verifying for Tay the accuracy of any payments made, or required to be made, to Tay pursuant to this Agreement. Before beginning its audit, the Auditor shall execute an undertaking acceptable to each Party by which the Auditor agrees to keep confidential all information reviewed during the audit. Such audits shall be limited to once each Calendar Year and once with respect to records covering any specific period of time. Such auditor shall not disclose VYNE’s Confidential Information to Tay except to the extent necessary to confirm the accuracy of the financial reports and payments furnished by VYNE under this Agreement and the amount of any discrepancies. If the final result of the inspection reveals an undisputed underpayment, the underpaid amount shall be paid within thirty (30) days after the Auditor’s report. If that the final result of the inspection reveals an undisputed overpayment, the overpaid amount shall be applied as a credit against future royalty payments by VYNE. Tay shall bear the full cost of such audit unless such audit reveals an underpayment owed by VYNE of more than five percent (5%) from the reported amounts, in which case VYNE shall reimburse Tay for the Auditor’s services. From time to time Tay shall also have the right to request of VYNE and VYNE shall in receipt of such request provide to Tay such information as may reasonably be required for Tay to assess the conduct and performance of VYNE in carrying out its obligations under this Agreement.

(a)Each Party shall cause all Persons who perform activities for such Party under this Agreement to be under an obligation to assign (or, if such Party is unable to cause such Person to agree to such assignment obligation despite such Party’s using commercially reasonable efforts to negotiate such assignment obligation, provide a license under) their rights in any Inventions resulting therefrom to such Party, except where Applicable Law requires otherwise and except in the case of governmental, not-for-profit, and public institutions which have standard policies against such an assignment (in which case a suitable license, or right to obtain such a license, shall be obtained).
(b)Each Party shall promptly disclose to the other Party, in writing, the conception, discovery, development, generation, making or creation of (i) any Invention related to the composition of matter of a Compound or Product and (ii) any Joint Inventions, in each case, made by Persons who perform activities for it under this Agreement. Each Party shall execute and record assignments and other necessary documents consistent with such ownership promptly upon such other Party’s request.
9.2 Patent Prosecution and Maintenance.
9.2.1 Tay Patents and Joint Patents. VYNE has the first right, but not the obligation, through the use of internal counsel, or outside counsel reasonably acceptable to Tay, to prepare, file, prosecute, and maintain the Tay Patents (on behalf of and in the name of Tay) and the Joint Patents worldwide, at VYNE’s expense. To the extent, if any, there are one or more Compounds not Covered by an Tay or Joint Patent at the Effective Date, Tay shall promptly cooperate and assist VYNE in preparing and filing one or more patent applications claiming such Compounds and shall disclose the Compounds and related information in at least sufficient detail to permit an understanding of the nature of the inventions in relation to the Compounds by a practitioner reasonably skilled in the relevant technical or scientific area and to enable preparation and filing of said applications. VYNE shall keep Tay reasonably informed of all material steps with regard to the preparation, filing, prosecution, and maintenance of the Tay Patents and the Joint Patents, including by providing Tay with a copy of material communications to and from any patent authority regarding such Patents, and by providing Tay drafts of any material filings or responses to be made to such patent authorities sufficiently in advance of submitting such filings or responses so as to allow for a reasonable opportunity for Tay to review and comment thereon. VYNE shall consider in good faith the requests and suggestions of Tay with respect to such VYNE drafts and with respect to strategies for filing and prosecuting such Patents. If VYNE decides not to prepare, file, prosecute, or maintain any Tay Patent or Joint Patent in a Country and there are no other Tay Patents or Joint Patents in such Country, VYNE shall provide reasonable prior written notice to Tay of such intention (which notice shall, in any event, be given no later than sixty (60) days prior to the next deadline for any action that may be taken with respect to such Joint Patent in such Country), and Tay shall thereupon have the option, in its sole discretion, to assume the control and direction of the preparation, filing, prosecution, and maintenance of such Patent at its sole cost and expense in such Country. Upon Tay’s written acceptance of such option, Tay shall assume the responsibility and control for the preparation, filing, prosecution, and maintenance of such Tay Patent or Joint Patent, as applicable. In such event, VYNE shall reasonably cooperate with Tay with respect to such Patent in such Country as provided under Section 9.2.3.

- 26 -

9.2.2 VYNE Patents. VYNE has the sole right, but not the obligation, through the use of internal or outside counsel, to prepare, file, prosecute, and maintain the Patents claiming Inventions made solely by VYNE and its Affiliates’ employees, agents, or independent contractors (the “VYNE Patents”) worldwide, at VYNE’s expense.
9.2.3 Cooperation. The Parties agree to cooperate fully in the preparation, filing, prosecution, and maintenance of the Tay Patents and the Joint Patents under this Agreement. Cooperation shall include:
(a)without limiting any other rights and obligations of the Parties under this Agreement, cooperating with respect to the timing, scope, and filing of such Patents to preserve and enhance the patent protection for Compounds and Products, including the manufacture and use thereof;
(b)executing all papers and instruments, or requiring its employees or contractors to execute such papers and instruments, so as to (i) effectuate the ownership of intellectual property set forth in Section 9.1.2; (ii) enable the other Party to apply for and to prosecute Patent applications; and (iii) obtain and maintain any Patent extensions, supplementary protection certificates, and the like with respect to the Tay Patents and the Joint Patents, in each case ((i), (ii), and (iii)) to the extent provided for in this Agreement;
(c)consistent with this Agreement, assisting in any license registration processes with applicable governmental authorities that may be available for the protection of a Party’s interests in this Agreement; and
(d)promptly informing the other Party of any matters coming to such Party’s attention that may materially affect the preparation, filing, prosecution, or maintenance of any such Patents.
9.2.4 Patent Term Extension and Supplementary Protection Certificate. VYNE has authority and sole discretion for making decisions regarding patent term extensions, including supplementary protection certificates and any other extensions that are now or become available in the future, wherever applicable, for VYNE Patents, Tay Patents, and Joint Patents in any Country and for applying for any extension or supplementary protection certificate with respect to such Patents in the Territory. Tay shall provide prompt and reasonable assistance, as requested by VYNE, including by taking such action as patent holder as is required under any Applicable Law to obtain such patent extension or supplementary protection certificate. VYNE shall pay all expenses with respect to obtaining the extension or supplementary protection certificate in the Territory. If VYNE desires that a patent term extension should be applied for a Tay Patent, Tay and VYNE shall discuss in good faith such patent term extension, provided that such decision shall be at VYNE’s sole discretion.
9.2.5 Patent Listings. VYNE will have the sole right to make all filings with Regulatory Authorities in the Territory with respect to VYNE Patents, and Joint Patents, including as required or allowed under Applicable Law, provided that with respect to Joint Patents such right shall be solely with respect to Products. VYNE shall notify Tay in writing of any Tay Patents that

- 27 -

it intends to list with Regulatory Authorities related to the Products and, prior to filing any such listing, consult with and consider in good faith the requests and suggestions of Tay regarding the same.
9.3 Patent Enforcement.
9.3.1 Notice. Each Party shall promptly notify the other Party in writing of any alleged or threatened infringement of an Tay Patent, Joint Patent or VYNE Patent by a Third Party in the Territory of which such Party becomes aware (including alleged or threatened infringement based on the development or commercialization of, or an application to market a product containing, a Compound or Product in the Territory).
9.3.2 Tay Patents and Joint Patents. VYNE has the first right, but not the obligation, to prosecute any such infringement of Tay Patents and Joint Patents at its sole expense. If VYNE prosecutes any such infringement, Tay has the right to join as a party to such claim, suit, or proceeding and participate with its own counsel at its own expense; provided that VYNE retains control of the prosecution of such claim, suit, or proceeding. If VYNE does not take commercially reasonable steps to prosecute the alleged or threatened infringement with respect to any such Tay Patent or Joint Patent (a) within six (6) months following the first notice provided above with respect to such alleged infringement, or (b) ten (10) Business Days before the time limit, if any, set forth in appropriate laws and regulations for filing of such actions, whichever comes first, then Tay may prosecute the alleged or threatened infringement at its own expense.
9.3.3 VYNE Patents. VYNE has the sole right, but not the obligation, to prosecute any such infringement of VYNE Patents at its sole expense, and VYNE shall retain control of the prosecution of such claim, suit, or proceeding.
9.3.4 Cooperation. The Parties shall cooperate in any infringement action pursuant to this Section 9.3. To the extent necessary for a Party to bring such an action, the other Party shall, where necessary, furnish a power of attorney solely for such purpose and shall join in, or be named as a necessary party to, such action. Unless otherwise set forth herein, the Party entitled to bring any patent infringement litigation in accordance with this Section 9.3 may settle such claim; provided that neither Party may settle any patent infringement litigation under this Section 9.3 in a manner that materially diminishes or has a material adverse effect on the rights or interest of the other Party, or in a manner that imposes any costs or liability on, or involves any admission by, the other Party, without the express written consent of such other Party. The Party commencing the litigation shall provide the other Party with copies of all pleadings and other documents filed with the court and shall consider reasonable input from the other Party during the course of the proceedings.
9.3.5 Recovery. Any recovery realized as a result of such litigation described in Section 9.3.1 or Section 9.3.2 (whether by way of settlement or otherwise) shall be first allocated to reimburse the Parties for their costs and expenses in making such recovery (which amounts shall be allocated pro rata if insufficient to cover the totality of such expenses). Any remainder after such reimbursement is made shall be retained by the Party that has exercised its right to bring the enforcement action; provided, that to the extent that any award or settlement (whether by judgment

- 28 -

or otherwise) is attributable to loss of sales with respect to a Product and retained by VYNE, such amounts shall be included as Net Sales hereunder with respect to such Product for the purposes of calculating amounts payable to Tay under Section 8.3.
9.4 Infringement Claims by Third Parties. If the manufacture, sale, or use of a Product in the Territory pursuant to this Agreement results in, or may result in, any claim, suit, or proceeding by a Third Party alleging patent infringement by VYNE (or its Affiliates or Sublicensees), VYNE shall promptly notify Tay thereof in writing. VYNE has the first right, but not the obligation, to defend and control the defense of any such claim, suit, or proceeding at its own expense, using counsel of its own choice. Tay may participate in any such claim, suit, or proceeding with counsel of its choice at its own expense. Without limitation of the foregoing, if VYNE finds it necessary or desirable to join Tay as a party to any such action, Tay shall, at VYNE’s expense, execute all papers and perform such acts as reasonably required. If VYNE elects (in a written communication submitted to Tay within a reasonable amount of time after notice of the alleged patent infringement) not to defend or control the defense of, or otherwise fails to initiate and maintain the defense of, any such claim, suit, or proceeding, within such time periods so that Tay is not prejudiced by any delays, Tay may conduct and control the defense of any such claim, suit, or proceeding at its own expense. Each Party shall keep the other Party reasonably informed of all material developments in connection with any such claim, suit, or proceeding. Any recoveries by VYNE of any sanctions awarded to VYNE and against a party asserting a claim being defended under this Section 9.4 shall be applied first to reimburse each Party for its reasonable out-of-pocket costs of defending or participating in such claim, suit, or proceedings, on a pro rata basis. The balance of any such recoveries shall be retained by, or provided to, VYNE and included in the calculation of Net Sales for the relevant Product for the purposes of calculating amounts payable to Tay under Section 8.3.
9.5 Invalidity or Unenforceability Defenses or Actions.
9.5.1 Notice. Each Party shall promptly notify the other Party in writing of any alleged or threatened assertion of invalidity or unenforceability of any of the Tay Patents that Cover a Compound or Product, Joint Patents, or VYNE Patents by a Third Party, in each case in the Territory and of which such Party becomes aware.
9.5.2 Tay Patents and Joint Patents. VYNE has the first right, but not the obligation, to defend and control the defense of the validity and enforceability of the Tay Patents and the Joint Patents at its own expense. Tay may participate in any such claim, suit, or proceeding related to the Tay Patents and the Joint Patents with counsel of its choice at its own expense; provided that VYNE shall retain control of the defense in such claim, suit, or proceeding. If VYNE elects not to defend or control the defense of the Tay Patents or the Joint Patents, or otherwise fails to initiate and maintain the defense of any such claim, suit, or proceeding, then Tay may conduct and control the defense of any such claim, suit, or proceeding, at its own expense; provided, that Tay shall obtain the written consent of VYNE prior to settling or compromising such defense, such consent not to be unreasonably withheld, conditioned, or delayed.
9.5.3 VYNE Patents. VYNE has the sole right, but not the obligation, to defend and control the defense of the validity and enforceability of the VYNE Patents at its own expense.

- 29 -

9.5.4 Cooperation. Each Party shall assist and cooperate with the other Party as such other Party may reasonably request from time to time in connection with its activities set forth in this Section 9.5, including by being joined as a party plaintiff in such action or proceeding, providing access to relevant documents and other evidence, and making its employees available at reasonable business hours. In connection with any such defense or claim or counterclaim, the controlling Party shall consider in good faith any comments from the other Party, shall keep the other Party reasonably informed of any steps taken, and shall provide copies of all documents filed, in connection with such defense, claim, or counterclaim. In connection with the activities set forth in this Section 9.5, each Party shall consult with the other as to the strategy for the defense of the Tay Patents, VYNE Patents, and Joint Patents.
9.6 Inventor’s Remuneration. Each Party shall be solely responsible for any remuneration that may be due such Party’s inventors under any applicable inventor remuneration laws.
9.7 Common Interest. All information exchanged between the Parties regarding the prosecution, maintenance, enforcement and defense of Patents under this ARTICLE 9 will be deemed to be Confidential Information of the disclosing Party. In addition, the Parties acknowledge and agree that, with regard to such prosecution, maintenance, enforcement, and defense, the interests of the Parties as collaborators are to, for their mutual benefit, obtain patent protection and plan patent defense against potential infringement activities by Third Parties, and as such, are aligned and are legal in nature. The Parties agree and acknowledge that they have not waived, and nothing in this Agreement constitutes a waiver of, any legal privilege concerning Patents under this ARTICLE 9, including privilege under the common interest doctrine and similar or related doctrines. Notwithstanding anything to the contrary in this Agreement, to the extent a Party has a good faith belief that any information required to be disclosed by such Party to the other Party under this ARTICLE 9 is protected by attorney-client privilege or any other applicable legal privilege or immunity, such Party shall not be required to disclose such information and the Parties shall in good faith cooperate to agree upon a procedure (including entering into a specific common interest agreement or disclosing such information on a “for counsel eyes only” basis or similar procedure) under which such information may be disclosed without waiving or breaching such privilege or immunity.
ARTICLE 10 CONFIDENTIALITY AND NON-DISCLOSURE
10.1 Confidentiality Obligations. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the Parties, during the Term and for ten (10) years thereafter, the receiving Party shall keep confidential and shall not publish or otherwise disclose, and shall not use for any purpose other than as expressly provided for in this Agreement, any Confidential Information furnished or otherwise made known to it, directly or indirectly, by the other Party, and each Party shall keep confidential and shall not publish or otherwise disclose the terms of this Agreement except as permitted herein. Each Party may use the other Party’s Confidential Information only to the extent required to accomplish the purposes of this Agreement, including exercising its rights and performing its obligations under this Agreement. Each Party

- 30 -

shall use at least the same standard of care as it uses to protect its own proprietary or confidential information (but no less than reasonable care) to ensure that its employees, agents, consultants, contractors, and other representatives do not disclose or make any unauthorized use of the other Party’s Confidential Information. Each Party shall promptly notify the other upon discovery of any loss or unauthorized use or disclosure of the other Party’s Confidential Information.
10.2 Exceptions. The obligations of confidentiality and non-use set forth in Section 10.1 above do not apply to any information that the receiving Party can demonstrate by written evidence:
10.2.1 is already known to the receiving Party, other than under an obligation of confidentiality, at the time of disclosure by the disclosing Party;
10.2.2 is now, or hereafter becomes, generally available to the public or otherwise part of the public domain through no fault of the receiving Party;
10.2.3 is disclosed to the receiving Party by a Third Party who had no obligation to the disclosing Party not to disclose such information to others; or
10.2.4 was independently discovered or developed by the receiving Party without the use of Confidential Information belonging to the disclosing Party.
Specific aspects or details of Confidential Information shall not be deemed to be within the public domain or in the possession of the receiving Party merely because the Confidential Information is embraced by more general information in the public domain or in the possession of the receiving Party. Further, any combination of Confidential Information shall not be considered in the public domain or in the possession of the receiving Party merely because individual elements of such Confidential Information are in the public domain or in the possession of the receiving Party unless the combination and its principles are in the public domain or in the possession of the receiving Party.
10.3 Permitted Disclosures.
10.3.1 Pursuant to Applicable Law. Each Party may disclose Confidential Information to the extent that such disclosure is, in the reasonable opinion of the receiving Party’s legal counsel, required to be disclosed pursuant to law, regulation, or a valid order of a court of competent jurisdiction or other supra-national, federal, national, regional, state, provincial, or local governmental body of competent jurisdiction, provided that the receiving Party shall first have given prompt written notice (and to the extent possible, at least five (5) Business Days’ notice) to the disclosing Party and given the disclosing Party a reasonable opportunity to take whatever action it deems necessary to protect its Confidential Information. If no protective order or other remedy is obtained, or the disclosing Party waives compliance with the terms of this Agreement, the receiving Party shall furnish only that portion of Confidential Information which the receiving Party is advised by counsel is legally required to be disclosed; for clarity, disclosures required in the reasonable opinion of the receiving Party’s legal counsel to the U.S. Securities and Exchange Commission (or equivalent foreign agency) shall be subject to the following Section 10.3.2.

- 31 -

10.3.2 Securities Exchange Filings. The Parties acknowledge that either or both Parties (or its Affiliates) may be obligated to make one or more filings (including to file a copy of this Agreement) with the U.S. Securities and Exchange Commission (or equivalent foreign agency) or a governmental authority. Each Party may make such a required filing, provided that if such filing includes a copy of this Agreement it will (a) submit in connection with such filing a copy of this Agreement in a form mutually agreed by the Parties in advance or, if, despite the reasonable efforts of the filing Party a form mutually agreed by the Parties cannot be agreed in advance, redacted to the extent permitted by Applicable Law, based on advice of filing Party’s counsel (the “Redacted Agreement”), (b) request, and use reasonable efforts consistent with Applicable Laws to obtain, confidential treatment of all terms redacted in the Redacted Agreement, for the Term of the Agreement and ten (10) years thereafter, and (c) unless otherwise agreed in writing by the other Party, request an appropriate extension of the term of the confidential treatment period if legally justifiable. For clarity, following a request from a governmental authority to change the redactions requested by a Party in the Redacted Agreement, a Party will not be in breach of this Section 10.3.2 for unredacting those redactions rejected by the applicable governmental authority, provided that such Party shall provide the other Party with a notice of the required changes and a copy of the revised redactions. Each Party is responsible for its own legal and other external costs in connection with any such filing, registration, or notification.
10.3.3 Additional Permitted Disclosures. In addition to disclosures pursuant to Sections 10.3.1 and 10.3.2 and as otherwise expressly permitted by this Agreement, each Party may disclose Confidential Information belonging to the other Party if and to the extent such disclosure is reasonably necessary in the following instances:

(b)under appropriate conditions of confidentiality in connection with an actual or potential (i) permitted license or sublicense of its rights hereunder, (ii) debt, lease, or equity financing of such Party, (iii) merger, acquisition, consolidation, share exchange, or other similar transaction involving such Party and a Third Party, and (iv) co-funding or financing arrangement, provided that in each case ((i) to (iv)) the receiving Party takes reasonable and lawful actions to minimize the degree of such disclosure;
(c)under appropriate conditions of confidentiality to any Third Party that is or may be engaged to perform services in connection with the Development, Manufacturing, or Commercialization of the Products as necessary to enable such Third Party to perform such services;
(d)to any government agency or authority in connection with seeking government funding, support, or grants;
(e)filing, prosecuting, and maintaining Patents, and prosecuting and defending litigation, in each case as permitted by this Agreement; and

10.4 Use of Name. Except as expressly provided herein, neither Party shall mention or otherwise use the name, logo, or trademark of the other Party or any of its Affiliates (or any abbreviation or adaptation thereof) in any publication, press release, marketing and promotional material, or other form of publicity without the prior written approval of such other Party in each instance. The restrictions imposed by this Section 10.4 shall not prohibit either Party from making any disclosure identifying the other Party that, in the opinion of the disclosing Party’s counsel, is required by Applicable Law; provided that such Party shall submit the proposed disclosure identifying the other Party in writing to the other Party as far in advance as reasonably practicable (and in no event less than five (5) Business Days prior to the anticipated date of disclosure) so as to provide a reasonable opportunity to comment thereon.
10.5 Press Releases. The Parties agree to issue a joint press release substantially in a form agreed by the Parties and attached to this Agreement as Schedule 10.5 announcing the signature of this Agreement at or shortly after the Effective Date within the time-period as required by relevant securities laws. It is understood that each Party may desire or be required to issue subsequent press releases relating to this Agreement or activities hereunder. The Parties agree to consult with each other reasonably and in good faith with respect to the text and timing of such press releases prior to the issuance thereof. Notwithstanding the foregoing, neither Party may unreasonably withhold, condition, or delay consent to such releases by more than five (5) Business Days, and either Party may issue such press releases or make such disclosures to the U.S. Securities and Exchange Commission (or equivalent foreign agency) as it determines, based on advice of counsel, is reasonably necessary to comply with Applicable Laws or for appropriate market disclosure. Each Party shall provide the other Party with advance notice of legally required disclosures to the extent practicable, and to the extent possible, at least five (5) Business Days prior to such disclosure. Following the initial joint press release announcing this Agreement, either Party shall be free to disclose, without the other Party’s prior written consent, the existence of this Agreement, the identity of the other Party, and those terms of the Agreement which have already been publicly disclosed in accordance with this Section 10.5.
10.6 Publications. During the Term, the disclosure by either Party relating to any Compound or Product in any publication or presentation shall be in accordance with the procedure set forth in this Section 10.6. A Party (“Publishing Party”) shall provide the other Party with a copy of any proposed publication or presentation at least thirty (30) days prior to submission for publication so as to provide such other Party with an opportunity to recommend any changes to the Publishing Party that it reasonably believes are necessary to continue to maintain such Party’s Confidential Information in accordance with the requirements of this Agreement. The incorporation of such recommended changes shall not be unreasonably refused; and if such other Party notifies (“Publishing Notice”) the Publishing Party in writing, within thirty (30) days after receipt of the copy of the proposed publication or presentation, that such publication or presentation in its reasonable judgment (a) contains an Invention, solely or jointly conceived or reduced to practice by the other Party, for which the other Party reasonably desires to obtain patent

- 33 -

protection or (b) could be expected to have a material adverse effect on the commercial value of any Confidential Information disclosed by the other Party to the Publishing Party, the Publishing Party shall prevent such publication or delay such publication for a mutually agreed period of time and at the other Party’s request shall remove the other Party’s Confidential Information from the proposed publication or presentation. In the case of Inventions, a delay shall be for a period reasonably sufficient to permit the timely preparation and filing of a patent applications on such Invention, and in no event less than ninety (90) days from the date of the Publishing Notice.
10.7 Destruction of Confidential Information. Upon the effective date of the expiration or termination of this Agreement for any reason, the Parties shall, with respect to Confidential Information to which such other Party does not retain rights under the surviving provisions of this Agreement, as soon as reasonably practicable, return (at the written request of the disclosing Party) or destroy all copies of such Confidential Information in the possession of the other Party and confirm such destruction in writing to the other Party, provided that such other Party shall be permitted to retain one copy of such Confidential Information for the sole purpose of performing any continuing obligations hereunder, as required by Applicable Law, or for archival purposes. Notwithstanding the foregoing, such other Party also shall be permitted to retain such additional copies of or any computer records or files containing such Confidential Information that have been created solely by such Party’s automatic archiving and back-up procedures, to the extent created and retained in a manner consistent with such other Party’s standard archiving and back- up procedures, but not for any other use or purpose.

12.3 Notice of Claim. All indemnification claims in respect of a Party, its Affiliates, or its or their respective directors, officers, employees and agents shall be made solely by such Party to this Agreement (the “Indemnified Party”). The Indemnified Party shall give the indemnifying Party (the “Indemnifying Party”) prompt written notice (an “Indemnification Claim Notice”) of any Losses or discovery of fact upon which such Indemnified Party intends to base a request for indemnification under this ARTICLE 12, but in no event shall the Indemnifying Party be liable for any Losses that result from any delay by the Indemnified Party in providing such notice. Each Indemnification Claim Notice must contain a description of the claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss is known at such time). The Indemnified Party shall furnish promptly to the Indemnitee copies of all papers and official documents received in respect of any Losses and Third Party Claims.
12.4 Control of Defense. The Indemnifying Party may conduct and control, through counsel of its choosing, any action for which indemnification is sought, and if the Indemnifying Party elects to assume the defense thereof, the Indemnifying Party shall not be liable to the Indemnified Party for any legal expenses of other legal counsel or any other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof. The Indemnifying Party may settle any action, claim, or suit for which the Indemnified Party is seeking indemnification; provided that the Indemnifying Party shall first give the Indemnified Party advance written notice of any proposed compromise or settlement and such Indemnified Party provides prior written approval, such approval not to be unreasonably conditioned, withheld or

- 37 -

delayed. The Parties and their employees shall cooperate fully with each other and their legal representatives in the investigation, defense, prosecution, negotiation, or settlement of any such claim or suit. Each Party’s indemnification obligations under this ARTICLE 12 shall not apply to amounts paid by an Indemnified Party in settlement of any action with respect to a Third Party claim, if such settlement is effected without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned, or delayed. In no event shall the Indemnifying Party settle or abate any Third Party Claim in a manner that would diminish the rights or interests of the Indemnified Party, admit any liability, fault, or guilt by the Indemnified Party, or obligate the Indemnified Party to make any payment, take any action, or refrain from taking any action, without the prior written approval of the Indemnified Party.
12.5 Limitation of Liability. EXCEPT FOR DAMAGES PAYABLE FOR A PARTY’S BREACH OF ITS OBLIGATIONS UNDER ARTICLE 10 OR REQUIRED TO BE PAID PURSUANT TO A PARTY’S INDEMNIFICATION OBLIGATIONS UNDER THIS ARTICLE 12, NEITHER PARTY NOR ANY OF ITS AFFILIATES SHALL BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE, OR CONSEQUENTIAL DAMAGES, INCLUDING LOSS OF PROFITS OR BUSINESS INTERRUPTION, HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, TORT, NEGLIGENCE, BREACH OF STATUTORY DUTY OR OTHERWISE IN CONNECTION WITH THIS AGREEMENT OR THE EXERCISE OF ANY LICENSE GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS AGREEMENT SHALL EXCLUDE OR LIMIT A PARTY’S LIABILITY TO THE EXTENT THAT IT MAY NOT BE SO EXCLUDED OR LIMITED UNDER APPLICABLE LAW, INCLUDING ANY SUCH LIABILITY FOR DEATH OR PERSONAL INJURY CAUSED BY THAT PARTY’S NEGLIGENCE OR LABILITY FOR FRAUD OR FRAUDULENT MISREPRESENTATION.
12.6 Insurance. Each Party shall procure and maintain insurance, including product liability insurance, adequate to cover its obligations hereunder and consistent with normal business practices of prudent companies similarly situated. Such insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under this ARTICLE 12. Each Party shall provide the other Party with written evidence of such insurance upon request. Each Party shall provide the other Party with written notice at least thirty (30) days prior to the cancellation, non-renewal or material change in such insurance.
ARTICLE 13
TERM AND TERMINATION
13.1 Term. This Agreement shall commence on the Effective Date and, unless earlier terminated in accordance herewith, shall continue in force and effect on a Product-by-Product and Country-by-Country basis, until the expiration of the Royalty Term for such Product in such Country (such period, the “Term”). Upon the expiration (but not early termination) of this Agreement for all Products in a Country, the licenses granted by Tay to VYNE under Section 2.1 become non-exclusive, fully paid-up, royalty-free, and perpetual for such Country.

- 38 -

13.2 Termination for Convenience. VYNE may terminate this Agreement in its entirety or on a Product-by-Product and Country-by-Country basis, for any or no reason, upon ninety (90) days’ prior written notice to Tay.
13.3 Termination for Uncured Material Breach. Each Party may terminate this Agreement immediately upon written notice to the other Party if the other Party materially breaches its obligations under this Agreement and, after receiving written notice identifying such material breach in reasonable detail, fails to cure such material breach within sixty (60) days from the date of such notice (thirty (30) days for payment-related breaches); provided, that if any alleged breach by VYNE relates solely to a Product, then Tay may exercise its rights under this Section 13.3 solely with respect to such Product, as applicable; provided, further, that, such cure period shall be extended for up to an additional sixty (60) days upon the breaching Party providing a written plan that reasonably demonstrates the need for such additional time and continuing to use Commercially Reasonable Efforts to cure such breach. If either Party disputes (a) whether such material breach has occurred, or (b) whether the defaulting Party has cured such material breach, the Parties shall promptly resolve the dispute under Section 14.2. During the pendency of such a dispute, all of the terms and conditions of this Agreement remain in effect and the Parties shall continue to perform all of their respective obligations hereunder.
13.4 Termination for Insolvency. If either Party (a) files for protection under bankruptcy or insolvency laws, (b) makes an assignment for the benefit of creditors, (c) appoints or suffers appointment of a receiver or trustee over substantially all of its property that is not discharged within ninety (90) days after such filing, (d) is a party to any dissolution or liquidation,
(e) files a petition under any bankruptcy or insolvency act or has any such petition filed against it that is not discharged within ninety (90) days of the filing thereof, or (f) admits in writing its inability generally to meet its obligations as they fall due in the general course, then the other Party may terminate this Agreement in its entirety effective immediately upon written notice to such Party.
13.5 Rights in Bankruptcy.
13.5.1 Applicability of 11 U.S.C. § 365(n). All rights and licenses (collectively, the “Intellectual Property”) granted under or pursuant to this Agreement, including all rights and licenses to use improvements or enhancements developed during the Term, are intended to be, and shall otherwise be deemed to be, for purposes of Section 365(n) of the United States Bankruptcy Code (the “Bankruptcy Code”) or any analogous provisions in any other Country or jurisdiction, licenses of rights to “intellectual property” as defined under Section 101(35A) of the Bankruptcy Code. The Parties agree that the licensee of such Intellectual Property under this Agreement shall retain and may fully exercise all of its rights and elections under the Bankruptcy Code, including Section 365(n) of the Bankruptcy Code, or any analogous provisions in any other Country or jurisdiction. All of the rights granted to either Party under this Agreement shall be deemed to exist immediately before the occurrence of any bankruptcy case in which the other Party is the debtor.
13.5.2 Rights of non-Debtor Party in Bankruptcy. If a bankruptcy proceeding is commenced by or against either Party under the Bankruptcy Code or any analogous provisions in any other Country or jurisdiction, the non-debtor Party shall be entitled to a complete duplicate

- 39 -

of (or complete access to, as appropriate) any Intellectual Property and all embodiments of such Intellectual Property, which, if not already in the non-debtor Party’s possession, shall be delivered to the non-debtor Party within five Business Days of such request; provided, that the debtor Party is excused from its obligation to deliver the Intellectual Property to the extent the debtor Party continues to perform all of its obligations under this Agreement and the Agreement has not been rejected pursuant to the Bankruptcy Code or any analogous provision in any other Country or jurisdiction.
13.6 Effects of Termination. Upon any termination of this Agreement with respect to a Product in a Country (the “Terminated Product”), the following terms will apply.
13.6.1 Licenses. All licenses granted by Tay with respect to the Terminated Product will automatically terminate.
13.6.2 Sublicenses. All sublicenses granted pursuant to this Agreement shall terminate, except that at the request of any Sublicensee with respect to the Terminated Product Tay will, from the effective date of such termination, enter into a direct license with such Sublicensee, provided that such Sublicensee is not then in default of its sublicense agreement. Such direct license shall not obligate such Sublicensee to perform contractual obligations greater than those set forth in the applicable sublicense or Tay to perform contractual obligations greater than those set forth herein, the scope of such direct license shall be of the scope of the license sublicensed to such Sublicensee, and the amounts payable to Tay by such Sublicensee under such direct license shall be equivalent to the amounts Tay would have received from VYNE under this Agreement as a result of such Sublicensee’s activities had this Agreement remained in effect and such Sublicensee performed such activity under the sublicense agreement with VYNE.
13.6.3 Wind-Down. VYNE shall (a) responsibly wind-down, in accordance with accepted pharmaceutical industry norms and ethical practices, any on-going clinical studies with respect to the Terminated Product in which patient dosing has commenced and (b) at Tay’s written election, (i) transfer to Tay or its designee any such clinical studies to the extent permitted under Applicable Laws and accepted pharmaceutical industry norms and ethical practices, or (ii) if reasonably practicable and not adverse to patient safety, complete such trials and Tay shall reimburse VYNE its internal costs and external expenses associated therewith.
13.6.4 Confidential Information. Each Party shall immediately return or cause to be returned to the other Party or destroy if the other Party requests (and certify such destruction to such other Party) all Confidential Information with respect to the Terminated Product and all substances or compositions of the other Party or its Affiliates delivered or provided by or on behalf of such other Party in accordance with Section 10.7.
13.6.5 Regulatory Documentation. Unless this Agreement is terminated by VYNE pursuant to Section 13.3, VYNE shall provide and assign to Tay or its designee all Regulatory Documentation, including Regulatory Approvals, for the Terminated Products to the extent possible under Applicable Law in the Territory.

- 40 -

13.6.6 Transition Assistance. Upon Tay’s reasonable request, (a) VYNE shall provide such assistance as may be reasonably necessary or useful for Tay to continue the Exploitation of Terminated Products in the Territory, to the extent VYNE or its Affiliate is then performing or having performed such activities, and (b) VYNE shall provide Tay with copies of any promotional and marketing materials generated by or on behalf of VYNE with respect to Terminated Products prior to the effective date of termination. Tay shall reimburse VYNE’s internal costs and external expenses in connection with such transition assistance.
13.6.7 Inventory. Tay may purchase any and all of the inventory of Terminated Products held by VYNE or its Affiliates or sublicensees as of the date of termination, at a price equal to the transfer price paid by VYNE to Tay for such inventory.
13.6.8 Data. Unless this Agreement is terminated by VYNE pursuant to Section 13.3, VYNE shall (a) promptly provide to Tay all data, including clinical and pharmacovigilance data, generated by or on behalf of VYNE with respect to the Terminated Product (the “Terminated Product Data”), and (b) and hereby does grant to Tay as of the effective date of the termination, a worldwide, non-exclusive, perpetual, royalty-free license, with the right to sublicense through multiple tiers, under the Terminated Product Data to Exploit the Terminated Product.
13.6.9 Intellectual Property. Unless this Agreement is terminated by VYNE pursuant to Section 13.3, VYNE hereby grants to Tay, effective upon the effective date of termination:
(a)a worldwide, exclusive, perpetual, license, with the right to sublicense through multiple tiers, under Know-How and Patents Controlled by VYNE that comprise or claim (i) Inventions made solely by VYNE and its Affiliates’ employees, agents, or independent contractors in the conduct of activities under this Agreement or (ii) any Joint Invention, in each case of (i) and (ii) to Exploit the Terminated Products;
(b)a worldwide, non-exclusive, perpetual, license, with the right to sublicense through multiple tiers, under all Know-How and Patents Controlled by VYNE that are necessary for the Exploitation of Terminated Products (other than Know-How relating to and Patents claiming the Manufacture of Terminated Products or those Patents set forth Section 13.6.9(a)) to Exploit the Terminated Products; and
(c)a right to negotiate in good faith for a license under Know-How and Patents Controlled by VYNE that are necessary or reasonably useful for the Manufacture of the Terminated Products on terms and conditions, and for economics value, to be negotiated in good faith by the Parties; provided, that if the Parties cannot agree on such terms, conditions, and economics after ninety (90) days despite having used good faith efforts to do so, then the Parties shall resolve such dispute using the same terms set forth in Exhibit 3.2 of the Option Agreement, applied mutatis mutandis.
13.6.10 Royalties. Unless this Agreement is terminated by Tay pursuant to Section 13.3 (Termination for Uncured Material Breach), in consideration for the rights granted to

- 41 -

Tay under Section 13.6.9, during the remainder of the Royalty Term for the applicable Terminated Product, Tay shall make quarterly, non-refundable, non-creditable royalty payments to VYNE on the annual Net Sales of all Terminated Products Covered by Patents Controlled by VYNE that are sold by or on behalf of Tay, its Affiliates or sublicensees in the Territory at the same rate and on the same terms that would have been payable to Tay under Section 8.3; provided, however, that for the purposes of this Section 13.6.10 the applicable royalty rates set forth in Section 8.3.1 shall be deemed to be reduced by: (a) [***] of the otherwise applicable rate if the effective date of termination of the Agreement is prior to Initiation of a Phase 1 Clinical Trial of a Product, (b) [***] of the otherwise applicable rate if the effective date of termination of the Agreement is prior to Initiation of a Phase 2 Clinical Trial of a Product, or (c) [***] of the otherwise applicable rate if the effective date of termination of the Agreement is prior to Initiation of a Phase 3 Clinical Trial of a Product. For clarity, in the case of termination by Tay pursuant to Section 13.3 (Termination for Uncured Material Breach), Tay shall not be required to pay any additional consideration for the rights granted to Tay under Section 13.6.9.
13.7 Accrued Rights; Surviving Obligations. Termination or expiration of this Agreement for any reason shall be without prejudice to any rights that have accrued to the benefit of a Party prior to such termination or expiration. Such termination or expiration shall not relieve a Party from obligations that are expressly indicated to survive the termination or expiration of this Agreement. Without limiting the foregoing, the following Articles and Sections of this Agreement shall survive the termination or expiration of this Agreement for any reason: Article 1 (to the extent such defined terms are used in other surviving sections), Section 4.4, Section 8.7, Section 8.8, Section 9.1, Article 10, Section 11.3, Section 12.1 (with respect to causes of action for which the cause of action arose prior to the effect of termination), Section 12.2 (with respect to causes of action for which the cause of action arose prior to the effect of termination), Section 12.3, Section 12.4, Section 12.5, Section 13.6, this Section 13.7, and Article 14.
ARTICLE 14 MISCELLANEOUS
14.1 Governing Law. This Agreement and all disputes arising out of or related to this Agreement or any breach hereof shall be governed by and construed under the laws of the England and Wales, without giving effect to any choice of law principles that would require the application of the laws of a different province or territory.
14.2 Dispute Resolution. The Parties irrevocably submit to the exclusive jurisdiction of the courts of England and Wales; provided, however, that each Party may institute judicial proceedings in any other jurisdiction against the other party or anyone acting by, through or under such other party, in order to enforce the instituting party’s rights hereunder through reformation of contract, specific performance, injunction or similar equitable relief.
14.3 Equitable Relief; Court Actions. Notwithstanding anything to the contrary in this Agreement, given the unique nature of the rights granted under the Option Agreement and this Agreement and the competitive damage that a Party may suffer upon a breach of ARTICLE 10 by the other Party, the Parties agree that monetary damages may not be a sufficient remedy for any breach by a Party of ARTICLE 10. In addition to all other remedies, a Party shall be entitled to

- 42 -

seek specific performance and injunctive and other equitable relief as a remedy for any breach or threatened breach of ARTICLE 10 by the other Party.
14.4 Entire Agreement; Amendments. This Agreement, including its exhibits, and the agreements entered into by the Parties pursuant to this Agreement, constitute the entire, final, and complete agreement and understanding between the Parties with respect to its subject matter and replaces and supersede all prior discussions and agreements between them with respect to the subject matter hereof. No modification of any terms or conditions hereof shall be effective unless made in writing and signed by a duly authorized representative of each Party.
14.5 Severability. If any provision of this Agreement is, becomes, or is deemed invalid or unenforceable by any court or other competent authority having jurisdiction, the remainder of this Agreement shall remain unimpaired and the Parties shall promptly negotiate in good faith to amend such invalid or unenforceable provision to conform to applicable laws so as to be valid and enforceable and best accomplish the original intent of the Parties.
14.6 Waiver and Non-Exclusion of Remedies. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless it is in writing and signed by the Party waiving such term or condition. The waiver by either Party hereto of any right hereunder or of a breach by the other Party shall not be deemed a waiver of any other right hereunder or of any other breach by such other Party whether of a similar nature or otherwise.
14.7 Force Majeure. Each Party shall be excused from liability for the failure or delay in performance of any obligation under this Agreement by reason of any event beyond such Party’s reasonable control and which is not reasonably foreseeable, including acts of God, fire, flood, explosion, earthquake, pandemic, or other natural forces, war, civil unrest, acts of terrorism, accident, destruction, or other casualty, any lack or failure of transportation facilities, any lack or failure of supply of raw materials or supplies, or any other event similar to those enumerated above. Such excuse from liability shall be effective to the extent and duration of the events causing the failure or delay in performance and provided that the Party has not caused such events to occur. Notice of a Party’s failure or delay in performance due to force majeure must be given to the other Party as soon as reasonably practicable after its occurrence. All delivery dates under this Agreement that have been affected by force majeure shall be tolled for the duration of such force majeure.
14.8 Independent Contractors. The relationship of the Parties is that of independent contractors, and nothing in this Agreement shall be construed to create a partnership, joint venture, franchise, employment, or agency relationship between the Parties. Neither Party shall be considered the agent of the other Party for any purpose whatsoever and neither Party has any authority to enter into any contract or assume any obligation for the other Party or to make any warranty or representation on behalf of the other Party.
14.9 Assignment. This Agreement is binding upon and inure to the benefit of the respective successors and assigns of the Parties. Neither Party may assign its rights and obligations under this Agreement, in whole or in part, without the prior written consent of the other Party (such

Any purported assignment in violation of this Section 14.9 is null and void.
