 SECOND AMENDMENT 

WHEREAS the Massachusetts Institute of Technology (“MIT”) and Genetix Pharmaceuticals Inc. of Cambridge, Massachusetts
(“Genetix” or “Company,” formerly Innogene Pharmaceuticals, Inc.) are parties to the Patent License Agreement (“License Agreement”) entered into on December 18, 1996; and 

WHEREAS Genetix currently lacks sufficient cash funds to substantially advance the development of its lead product candidate
LentiGlobinTM which incorporates technology subject to the License Agreement or to make further payments under the License Agreement which could become due; and 
 WHEREAS Genetix has entered into a subsequent letter agreement (“Letter Agreement”) with MIT dated April 9, 2004 and providing for conditional retraction of MIT’s earlier Letter of
Termination upon a financing of Genetix and certain payments by Genetix to MIT, as well as a further agreement (“First Amendment”) dated December 12, 2003 amending the License Agreement to incorporate certain new technology and
payments by Genetix; and 
 WHEREAS Genetix’ lead product in development, LentiGlobinTM, incorporates multiple
technologies requiring licenses from multiple parties each bearing royalty, license fee, and sublicensing terms which are substantial and in the case of sublicensing terms are prohibitive in and of themselves, and Genetix now anticipates requirement
for an additional license from at least one further party; and 
 WHEREAS [***]; and 

WHEREAS Genetix has not entered into any sublicense under the License Agreement nor has it initiated negotiation of such a sublicense;
and 
 WHEREAS Genetix desires to realize the equity investment so that it may continue operations and advance LentiGlobinTM
into human clinical trials, and Genetix has therefore proposed to MIT to amend Section 4.1.d of the License Agreement to eliminate the requirement for certain payments to made pursuant to future sublicenses, for the satisfaction of new
investors; and

 WHEREAS MIT stands to benefit financially from receipt by Genetix of the investment,
through the intended further development and potential commercialization of LentiGlobinTM under the License Agreement as amended below; 
 Now, therefore, MIT and Genetix agree as follows (the “Second Amendment”): 
 1. The first sentence of Section 4.1.d of the License Agreement shall be amended and replaced with the following: 
 “The following proportion of payments received from sublicensees in consideration for the LICENSED PRODUCTS and LICENSED PROCESSES: 

 

	 	i.	[***]; or 

  

	 	ii.	[***].” 

 The remainder of
the same Section, beginning “Provided, however...” shall remain as previously agreed and written. 
 2. The License
Agreement, the Letter Agreement, the First Amendment, and this Second Amendment reflect the entire Agreement between MIT and Genetix. This Agreement may only be modified in writing signed by a duly authorized representative of MIT and a duly
authorized representative of Genetix.

	 	((b))	[***]; and 

  

	 	((c))	[***]; and
