ARTICLE12- GOVERNING LAW AND DISPUTE RESOLUTION

12.1	Governing Law. This Agreement and the documents to be entered into pursuant to it, and all matters arising and connected with it are governed by and shall be construed in accordance with the laws of New York.

12.2

Disputes. The Parties recognize that disputes as to certain matters may from time to time arise that relate to either Party’s rights or obligations hereunder. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes arising under this Agreement in an expedited manner by mutual cooperation. To accomplish this objective, the Parties agree to follow the following procedures if and when a dispute arises under this Agreement:

(a)

Elevate to Senior Management.Any such disputes shall be first referred by either Party to senior representatives designated by each Party; the President of Stiefel for GSK and Chief Executive Officer for Welichem. In the event that the aforementioned senior management of GSK and Welichem cannot resolve the dispute within [***] of being requested by a Party to resolve a dispute, either Party may, by written notice to the other, invoke the dispute resolution provisions ofSection 12.2(b).

(b)

Resolution by theCourts.

(i)

The courts of New York shall have exclusive jurisdiction to settle any Disputes and hear and decide any Proceedings.

(ii)

The Parties agree that the court referred to inSection 12.2(b)(i)are the most appropriate and convenient courts to settle any Disputes and hear and decide any Proceedings and, accordingly, that they shall not argue to the contrary.

12.3	Injunctive Relief. Notwithstanding the foregoing dispute resolution procedures, in the event of an actual or threatened breach hereunder, the aggrieved Party may seek restraining orders, specific performance or other injunctive relief without submitting to such dispute resolution procedure.

ARTICLE13- TERMINATION

13.1	Expiration. This Agreement shall remain in effect until the longer of (i) the payment by GSK to Welichem of the final Milestone Payment due to Welichem under this Agreement, and (ii) the term of the Safety Data Exchange Agreement.

(a)

any representation or warranty of Welichem shall have become untrue in any material respect or Welichem has breached any covenant or agreement of Welichem set forth in this Agreement, and (b) such breach or misrepresentation is not capable of being cured; or

(b)

a material breach of any provision of this Agreement, the [***] TTA or the Safety Data Exchange Agreement has been committed by Welichem, Celestial, BWTP or other Affiliates of Welichem, and such breach has not been waived by GSK and such breach is not cured within [***] after written notice thereof or, in the reasonable determination of GSK, is incapable of being cured. For greater certainty, the failure to complete the Second Closing shall not be deemed a “material breach” under this Agreement if Welichem has used its best efforts to achieve such Second Closing.

13.3

Effects of Termination.In the event of termination of this Agreement, this Agreement shall thereafter become void and have no effect, and no Party shall have any Liabilities to any other Party, their successors or permitted assigns or with respect to their respective Affiliates; provided, however, that the obligations set forth in [***]shall survive termination of this Agreement. For the avoidance of doubt, termination of this Agreement (for any cause, including because of Welichem’s breach) shall not affect the ownership with respect to theEx-China Assets that has been transferred to GSK at the First Closing or if the Second Closing occurs, the ownership with respect to the China Assets that has been transferred to GSK at the Second Closing.
