 Certain confidential information contained in this document, marked by [**], has been
omitted because the information (i) is not material and (ii) would likely cause competitive harm to the Company if publicly disclosed. 
  

 
shall be for the license to FIX Know-How due upon Licensee’s confirmation of complete transfer of the Transfer Documentation and payable within thirty
(30) days of receipt of invoice from St. Jude. This license fee payment is nonrefundable and is not creditable against any other payments due to St. Jude under this Agreement. 

4.02.     Licensee agrees to pay to St. Jude a non-refundable annual maintenance fee of five
thousand dollars ($5,000) U.S. due by March 1 of each year beginning on March 1, 2020 and payable within thirty (30) days of receipt of invoice by Licensee. This annual fee payment may be reduced each year by the amount of any royalty
payments made to St. Jude for prior calendar year sales of AAV Product pursuant to Section 4.03 below. For example, the annual payment due March 1, 2020 may be reduced by the amount of any royalty payments made to St. Jude for sales of AAV
Product recorded for calendar year 2019. 
 4.03.     Licensee agrees to pay to St. Jude, on a semi-annual basis, the following
royalties: 
  

	 	(i)	 In exchange for the license to Patent Rights, a royalty of [**] of Net Sales of all FIX Products sold by
Licensee, Affiliates or Sub-Licensees. The royalty shall be payable on a country-by-country and product-by-product basis following the first commercial sale of a FIX Product to expiry of the last to expire Valid Claim of Patent Rights; and 



 

	 	(ii)	 In exchange for the license to FIX Know-How, a royalty of [**] of Net
Sales of all AAV Products sold by Licensee, Affiliates or Sub-Licensees payable on a country-by-country and product-by-product basis for a period, which respect to each such AAV Product, of ten (10) years following the first commercial sale of the AAV Product.



 For the avoidance of doubt, royalties are payable once only per unit of FIX Product or AAV Product (as applicable)
sold. 
 4.04     For purposes of calculating the royalty due to St. Jude, Net Sales received in a foreign currency shall be
converted into U.S. dollars using the arithmetic average of the daily exchange rate (e.g. GBP/USD) for the calendar half-year (i.e. final day of June or December) using an exchange rate quoted by the Bank of England. 

4.05     Royalty Offset. At any time following the approval of a FIX Product by the FDA, St. Jude may submit a written request to Licensee
for a reasonable quantity of such FIX Product for noncommercial use. Licensee may accept or deny any such request at its sole discretion. If Licensee accepts such a request and provides FIX Product to St. Jude or its designees, Licensee shall be
entitled to reduce its royalty obligation set forth in Section 4.03 by an amount to be agreed upon by the Parties that is intended to approximate the cost incurred by Licensee in providing the FIX Product. 

ARTICLE V - PAYMENT AND RECORDS 
 5.01.
    Within sixty (60) days of June 30 and December 31 of each calendar year following the first commercial sale by Licensee of an AAV Product, Licensee shall provide St. Jude with a statement setting forth for each
of the AAV Products sold by Licensee, Affiliates or Sub-Licensees (without duplication) during the preceding six-month period (from January 1 to June 30 or
July 1 to December 31), on a country-by-country basis the Net Sales for each AAV Product for the six month period, a listing of applicable reductions and
deductions on an aggregate basis, the total royalty owed for the six month period based on Net Sales of each AAV Product in U.S. dollars, together with exchange rates used for conversion of foreign proceeds, and any credits taken based on prior
payment of an annual maintenance fee according to Article 4.02 or royalty offset

any payment due for the applicable six month period. 
 5.02.     Licensee shall maintain, and shall cause its Affiliates and Sub-Licensees to maintain, usual books of account and records showing all sales of AAV Product and Net Sales attributable to such sales. Such books and records shall be open to inspection, audit and copying, during
usual business hours, by an independent certified public accountant to whom Licensee has no reasonable objection, for two (2) years after the calendar year to which they pertain, for purposes of verifying the accuracy of the royalties paid by
Licensee pursuant to this Agreement. Should it be determined by the audit that a discrepancy in the accuracy of royalties paid by Licensee has resulted in a greater than [**] loss of royalty income to St. Jude, Licensee agrees to reimburse St. Jude
for its expenses related to performance of the audit, as well as for unpaid royalties to St. Jude, otherwise the costs of the audit shall be paid by St. Jude. Should it be determined by the audit that a discrepancy in the accuracy of royalties paid
by Licensee has resulted in an overpayment of royalty income to St. Jude, St. Jude agrees to refund Licensee by the amount of the overpayment.
