	 	3.3.1	Description of Categories: 

  

	 	3.3.1.1	To meet the requirements of the term “Novel Vector” (as used in Categories la and lb(ii)), there must be neither any dominating Third Party patent, including any Penn-owned patent rights other than those
licensed under this Agreement with respect to the vector per se (i.e., no Third Party patent or Penn-owned patent rights beyond those licensed under this Agreement is required in order to make, have made, use, import, offer for sale or sell the
vector for the higher royalty level to apply). Licenses from Penn or GSK to ReGenX for genes used, promoters used other than those which are part of the vector as described in Penn Patent Rights and the like in the vector will not affect the royalty
pursuant to this provision. If any dominating Third Party patent or any Penn-owned patent other than those licensed under this Agreement issues at any time during the term of this Agreement with respect to a vector licensed hereunder, then the
royalty level will immediately drop to the “Refinement” level (Category lb above) for any Licensed Product containing such vector. 

  

	 	3.3.1.2	As used in Category 2 of the Table in Section 3.3, a “therapeutic use” shall mean use in the prevention and/or treatment of a disease in a patient. For the

	 	avoidance of doubt, ReGenX shall have no obligation under Section 3.3 or under any other provision of this Agreement to pay any royalties on any “reach-through” basis for any reason whatsoever, including
without limitation, on the basis of the use by ReGenX of any subject matter recited in a Valid Claim in the development, selection or advancement of any Licensed Product, except only as may be expressly provided under Category lb(ii) in
Section 3.3 above. 

  

	 	3.3.1.3	In the event that any Licensed Product does not fall into any of the Categories 1-3 above, ReGenX shall pay to GSK a royalty of **** based upon Net Sales of such Licensed Product, subject always to the reductions in
royalty rates set forth in Sections 3.3.4 and 3.3.5, and subject always to the terms and conditions of this Section 3.3. 

  

	 	3.3.2	One Royalty: For any single Licensed Product, ****. In addition, the **** royalty shall be subject to the **** provided below.

 STACKING ROYALTY CALCULATIONS 

R = (C*(A/(A+B))) 
 Where 

R = Reduction of GSK royalty. 
 A =
Unreduced GSK royalty, 
 B = sum of all Third Party royalties, 

C = increment of projected total royalty above ****. 

Example Calculation: 
  

			
	assume:	 	i) all Third Party royalties = ****%
		 	ii) unreduced GSK royalty = ****%
		 	iii) projected total royalty = ****%

  

			
		  	R = (****-****)*(****/(**** + ****))
		  	R = (*********)
		  	R = ****
		  	GSK Stacked Royalty = ****-**** = ****%

 Notwithstanding the foregoing, ReGenX will pay to GSK no less than **** of the royalties that ReGenX would otherwise pay to
GSK if there were no royalties due to Third Parties. 
  

	 	3.3.6	Termination of Obligation to Pay Royalty: Subject to Section 3.3.4, ReGenX’s obligation hereunder for payment of a royalty on the Net Sales of Licensed Products in a given country will end on a country by
country basis when there is no Valid Claim in that country claiming the Licensed Product. 

 3.4 Sublicense Fees. ReGenX shall pay GSK a
percentage of any sublicense fees (****) received by ReGenX for the Penn Patent Rights from any sublicensee; ****. The applicable percentage due to GSK for each sublicense shall be:

quarterly and annual accounts, as confirmed by GSK’s auditors. If government regulations prevent remittances from a foreign country with respect to sale made in that country, the obligation to pay royalties on the sale in that country shall be
suspended until such remittances are possible.

(a) first, to reimburse the costs and expenses (including reasonable attorneys’ fees and costs) of ****, **** and ****; (b) second, to **** to account for lost sales or lost profits (to the extent that damages are awarded for lost
sales or lost profits from the sale ****); (c) third, to **** to the extent necessary to account for the royalties that would have been payable to **** but for the lost sales or lost profits; and (d) the remainder to the account of the
**** that undertake such actions to the relative extent of their financial participation therein.

	 	7.2.4	If ReGenX elects to pursue an infringer under Section 7.2.2 above and ReGenX fails to prosecute such infringement, then GSK may prosecute such infringement at its own expense. In such event, financial recoveries
will be entirely retained by GSK. 

  

	 	7.2.5	In any action to enforce any of the Penn Patent Rights, either Party, at the request and expense of the other Party shall cooperate to the fullest extent reasonably possible, including in the event that if either Party
is unable to initiate or prosecute such action solely in its own name, the other Party shall join such action voluntarily and shall execute all documents necessary to initiate litigation to prosecute and maintain such action. This provision shall
not be construed to require either Party to undertake any activities, including legal discovery, at the request of any Third Party except as may be required by lawful process of a court of competent jurisdiction. 


7.3 Defense of Infringement Claims. 
  

	 	7.3.1	In the event ReGenX or GSK becomes aware that ReGenX’s or any of its Affiliates’ or sublicensees’ practice of the Penn Patent Rights is the subject of a claim for patent infringement by a Third Party,
that Party shall promptly notify the other and the Parties shall consider the claim and the most appropriate action to take. ReGenX shall cause each of its Affiliates and sublicensees to notify ReGenX promptly in the event such entity becomes aware
that its practice of the Penn Patent Rights is the subject of a claim of patent infringements by another. ReGenX shall have the right to control the defense of any such suit brought against ReGenX or any of its Affiliates or sublicensees and shall
do so at its own expense. ReGenX shall have the right to require GSK’s and Penn’s reasonable cooperation in any such suit, upon written notice to GSK and Penn, and GSK and Penn shall have the obligation to participate and ReGenX shall bear

 10.1 Relationship. Nothing in this Agreement shall be deemed to establish a
relationship of principal and agent between ReGenX and GSK, nor any of their agents or employees for any purpose whatsoever, nor shall this Agreement be construed as creating any other form of legal association or arrangement which would impose
liability upon one Party for the act or failure to act of the other Party. 
 10.2 Assignment. The rights and obligations of ReGenX and GSK hereunder
shall inure to the benefit of, and shall be binding upon, their respective successors and assigns. Neither Party may assign its rights under this Agreement without the prior written consent of the other Party, such consent not to be unreasonably

prototypes and other commodities, articles and information, including the Arms Export Control Act as amended in the Export Administration Act of 1979, and that the Parties’ obligations are contingent upon compliance with applicable United
