GSK and Auxilium are sometimes referred to herein individually as a “Party” and collectively as the “Parties”.

RECITALS

WHEREAS, GSK and Auxilium are parties to that certain Co-promotion Agreement, dated as of May 18, 2012 (the “Agreement”), relating to the co-promotion of the Product in the Territory;

WHEREAS, the Parties mutually desire to terminate the Agreement as of August 2, 2013 and accordingly desire to amend the Agreement in accordance with the terms set forth in this Amendment; and

WHEREAS, Section 16.9 of the Agreement requires any amendment of the Agreement to be in writing and executed by the Parties.

NOW, THEREFORE, in consideration of the foregoing premises, and the mutual representations, warranties and covenants contained in this Amendment, and for other good and valuable consideration, the Parties agree as follows:

ARTICLE 1

ARTICLE 2

AMENDMENTS

2.1          New Section 3.3.  A new Section 3.3 shall be added to the Agreement by adding the following language immediately after Section 3.2(c)(vii):

“3.3        Mutual Termination Date.  Notwithstanding anything in this Agreement to the contrary, unless terminated earlier in accordance with Section 3.2, Auxilium and GSK each mutually agree that this Agreement shall terminate on August 2, 2013 (the “Mutual Termination Date”).  Prior to the Mutual Termination Date, the Parties shall continue to perform all of their respective obligations under this Agreement, subject to the terms and conditions of this Agreement.  For clarity, the Parties acknowledge and agree that the termination of this Agreement under this Section 3.3 constitutes an early termination but does not constitute expiration of this Agreement pursuant to Section 3.1 and that GSK will not be entitled to receive any Tail Payments as a result of such termination.”
