This AMENDMENT #4 TO THE RESEARCH, DEVELOPMENT AND LICENSE AGREEMENT (this "Amendment No. 4") is entered into and made effective as of the 10th day of April, 2014 (the "Amendment No. 4 Effective Date") by and between Isis Pharmaceuticals, Inc., a Delaware corporation, having its principal place of business at 2855 Gazelle Court, Carlsbad, CA 92010 ("Isis"), and Glaxo Group Limited, a company existing under the laws of England and Wales, having its registered office at 980 Great West Road, Brentford London TW8 9GS, United Kingdom ("GSK").  Isis and GSK are each referred to herein by name or as a "Party" or, collectively, as "Parties."


RECITALS


Whereas, Isis and GSK are parties to the Research, Development and License Agreement dated March 30, 2010, as amended (the "Agreement"); and


Whereas, Isis and GSK desire to amend certain terms of the Agreement solely with respect to the Collaboration Program focused on the [***] (the "GSK-5 Program"), including to extend the Collaboration Term for the GSK-5 Program to March 30, 2015, on the terms and conditions set forth herein.


Now, therefore, in consideration of the premises and mutual covenants herein contained, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and solely with respect to the GSK-5 Program, the Parties, intending to be legally bound, do hereby agree as follows:


Capitalized terms used but not defined herein shall have the meaning ascribed to such terms in the Agreement.

GSK-5 Program – Natural History Study.








	
a.

	
The Parties will conduct the Natural History Study as part of the GSK-5 Development Plan. GSK and Isis [***] a clinical research organization ("CRO") to conduct the Natural History Study, and Isis will thereafter negotiate and enter into an agreement with such CRO for the conduct of such study with terms reasonably acceptable to GSK (the "CRO Contract"), it being understood that GSK will provide Isis comments to the terms of the CRO Contract, if any, within [***] ([***]) Business Days of receiving a draft of such CRO Contract from Isis. Notwithstanding the preceding sentence, and subject to Section 1.b and Section 1.c, if GSK and Isis cannot agree on a term in the CRO Contract, [***] will have final decision-making authority with respect to such term (provided that, such decision is in accordance with the GSK-5 Development Plan and would not result in an increase in External Costs above [***]). For avoidance of doubt, nothing in this Amendment No. 4 requires Isis to amend any agreement between Isis and any Third Party CRO that is in effect as of the Amendment No. 4 Effective Date. The Parties intend that the CRO Contract will be executed by Isis as soon as reasonably practicable after the Amendment No. 4 Effective Date.

Isis will not make any changes to the Initial Natural History Study Protocol or authorize or direct the CRO to do any work that is outside the scope of the Initial Natural History Study Protocol that would result in External Costs above the Isis Natural History Study Cost Cap, without GSK's prior written consent. GSK will not make any changes to the Initial Natural History Study Protocol or authorize or direct the CRO to do any work that is outside the scope of the Initial Natural History Study Protocol that would increase Isis's internal FTE costs for the conduct of such Natural History Study as compared to Isis's internal FTE costs for the conduct of the Initial Natural History Study Protocol without Isis's prior written consent.

GSK will specify in its Notice to Continue whether the study design and endpoints for the multiple-dose portion of the PoC Trial for which GSK has authorized Isis to proceed are as set forth in (i) or (ii) above.
