 ARTICLE 2 

License 

2.1    Grant. Subject to the terms and conditions of this Agreement, LI-COR
hereby grants to Aura an exclusive, royalty-bearing, license (“License”) under the Licensed Patent, Improvements and Know-How to research, develop, make, have made, use, have used,
market, sell, have sold, distribute, have distributed, export and have imported Licensed Product for the Licensed Field in the Territory during the Term. Notwithstanding the foregoing, such License does not include the right to make or have made IR
Dye 700DX. 
 2.2    Sublicenses. Subject to the terms and conditions of this Agreement, Aura shall have the
right to grant sublicenses under the License to (a) to its Affiliates and (b) to Third Parties (“Sublicensee”), to make, have made, market, sell and have sold Licensed Product in the Licensed Field in the
Territory. Aura shall remain responsible for complying with all terms and conditions of this Agreement regardless of any grant to a Sublicensee or Affiliate. In addition, Aura shall require that each of its Affiliates and Sublicensees accept all of
the relevant terms and conditions of this Agreement as if such Affiliates or Sublicensees were a party to this Agreement, and shall provide LI-COR with a copy of each agreement with a Sublicensee upon execution of such agreement. For clarity, Aura
shall have no right to grant a sublicense to its Affiliates or any Third Party under the Licensed Patent and Know-How to make or have made IRDye 700DX in the Licensed Field in the Territory. Upon termination
or expiration of this Agreement for any reason, any Sublicensee not then in default under its agreement with Aura or an Affiliate shall have the right to seek a license directly from LI-COR. LI-COR agrees to negotiate such license in good faith under reasonable terms and conditions consistent with this Agreement; provided, however, whether LI-COR enters into any
such license shall be at the sole discretion of LI-COR. 

2.3    Consideration for Expanded Field. At any time during the Term,
LI-COR hereby agrees to consider any request by Aura to negotiate a non-exclusive, royalty-bearing license under the Licensed Patent, Improvements and Know-How to research, develop, make, have made, use, have used, market, offer for sale, sell, have sold, distribute, have distributed, export and import products for the diagnosis and treatment of cancers in
indications other than ocular cancers (the “Expanded Field”) in the Territory; provided, that LI-COR is not obligated to negotiate or grant any such license. It is understood generally
that the aggregate financial terms of a non-exclusive license in the Expanded Field is likely to be less than financial terms of an exclusive license of an identical scope.  

2.4    No Implied Rights or Licenses. Neither Party grants to the other Party any rights or licenses in or to any
patent, know-how or other intellectual property right, whether by implication, estoppel or otherwise, except to the extent expressly provided for under this Agreement.

schedule:

	 $[***]
	  	 	[	***] 
	 $[***]
	  	 	[	***] 
	 Total:
	  	$	[	***] 

 3.2    Royalty. In partial consideration for the license and rights granted to Aura
under this Agreement, Aura shall, on a country-by-country basis, during the Term pay LI-COR the following royalty
(“Royalty”) on Net Sales. The Royalties due shall be calculated on an incremental basis and paid annually. [***]. 
  

					
	 Annual Net Sales
	  	Royalty	 
	 [***]
	  	 	[	***]% 
	 [***]
	  	 	[	***]% 
	 [***]
	  	 	[	***]% 
	 [***]
	  	 	[	***]% 

 (a)    If the Royalty due for any calendar quarter is less than the Minimum Royalty
applicable for such calendar quarter and the total amount of Royalty paid for each of the calendar quarters in the same calendar year as such calendar quarter is less than the total Minimum Royalty due in the aggregate for such calendar quarters,
Aura shall pay LI-COR the Royalty plus the difference between the Minimum Royalty and the Royalty for such calendar quarter, to be trued up at the end of each calendar year. 

(b)    All such payments must be made quarterly, in accordance with Section 4.1 (b) and this
Article 3. In order to ensure LI-COR the full royalty payments contemplated hereunder, Aura agrees that in the event any Licensed Product is sold to an Affiliate or a Sublicensee or to a
corporation, firm, or association with which Aura has any agreement, understanding, or arrangement with respect to consideration (such as, among other things, an option to purchase stock or actual stock ownership, or an arrangement involving
division of profits or special rebates or allowances), the royalties to be paid hereunder for such Licensed Product will be based upon the greater of (x) the net selling price (per Net Sales) at which the purchaser of the Licensed Product
resells such product to the end user; (y) the fair market value of the Licensed Product; or (z) the net selling price (per Net Sales) of Licensed Product paid by the purchaser. 

  
 6 













 (c)    In the event that, on a country-by-country basis, the Licensed Product is not covered by a Valid Claim in a country and there is a Generic Product in such country, then the Royalty on Net Sales of Licensed Product in such country
due to LI-COR shall be reduced by [***]% for the remainder of the Term. 

(d)    In the event that Aura receives a communication from a Third Party alleging infringement of or notification of such
Third Party’s patent rights as they relate to the research, development, manufacture, or use of IRDye 700DX, Aura shall notify LI-COR of such communication, and Aura shall take into consideration LI-COR’s comments regarding such communication. In the event that Aura is required to pay Third Party Royalties in order to license rights to the IRDye 700DX, then Aura may deduct [***]of the Third Party
Royalties paid by Aura in such calendar quarter from the Royalty due to LI-COR for such calendar quarter, provided that in no event shall the Royalty due to LI- COR be
reduced by more than [***]. 
 3.3    Milestone Payments. In partial consideration for the license and rights
granted to Aura under this Agreement, Aura shall pay to LI-COR each of the following milestone payments (“Milestone Payments”) within [***] after the occurrence of the applicable
milestone (“Milestone”) only for the first achievement of the Milestone event below for each Licensed Product, whether such event results from the activities of Aura or its Affiliates.

	  	$	[	***] 
	 Total:
	  	$	[	***] 

 All Milestone Payments are non-refundable and
non-creditable against any other royalties, fees, or payments hereunder. For clarity, Milestone Payments are owed on a Licensed Product by Licensed Product basis. Notwithstanding the foregoing, with respect to
the development of more than one candidate constituting a Licensed Product, if any milestone payments have been made with respect to a candidate the development of which is abandoned by Aura and Aura pursues the development of a subsequent candidate
constituting part of such Licensed Product, all milestone payments previously made with respect to such abandoned candidate shall be credited towards the milestones that would otherwise be due and payable with respect to one or more subsequent
candidates. 
 3.4    Method of Payment. All payments to LI-COR hereunder
shall be made by deposit of United States Dollars in the requisite amount to such bank account as LI-COR may from time to time designate by written notice to Aura. With respect to sales not denominated in
United States Dollars, Aura shall convert applicable sales in foreign currency into United States Dollars based on the average of the conversion rate reported in The Wall Street Journal on the last working day of each month in the calendar quarter
of the applicable calendar quarter. Based 

  
 7 













 
on the resulting sales in USD, the then applicable royalties shall be calculated. The Parties may vary the method of payment set forth herein at any time upon mutual written agreement, and any
change shall be consistent with the local Law at the place of payment or remittance. 
 3.5    Late Payments. In
the event that any payment (other than a payment disputed in good faith) hereunder is not made when due, the amount due will accrue interest calculated at the annual rate of the sum of (a) four percent (4%) plus (b) the
prime interest rate quoted by The Wall Street Journal on the date said payment is due, the interest being compounded on the last day of each calendar quarter; provided that in no event will said annual interest rate exceed the maximum
interest rate allowed by law. Each such payment when made must be accompanied by all interest so accrued. Said interest and the payment and acceptance thereof will not negate or waive the right of LI-COR to
seek any other remedy, legal or equitable, to which it may be entitled because of the delinquency of any payment, including termination of this Agreement as set forth in Section 9.2. 

3.6    Taxes. All fees, royalties, and other payments are exclusive of any national, state, and local sales, use,
value added, and other taxes, customs duties, or similar tariffs and fees which Aura may be required to collect or pay. Should any tax or levy be made, Aura agrees to pay such tax or levy and indemnify LI-COR
against any claim for such tax or levy demanded. Aura shall pay any withholding taxes required by applicable Law. 
 ARTICLE 4 

Reports, Records, and Inspections 

4.1    Reports. 

(a)    Summary Reports. Not less than once every six (6) months, Aura shall provide LI-COR with a summary report, which must describe a summary-level review and/or update of the research, development, and commercialization activities undertaken by Aura and its Affiliates and Sublicensees with
respect to Licensed Product during the period covered by the report and/or update since the last report. Each such report shall include a summary of work completed, a summary of work in progress, a current schedule of anticipated regulatory
approvals, sublicensing efforts, if any, and market plans for introduction of Licensed Product. 
 (b)    Royalty
Reports. Aura shall provide LI-COR with quarterly royalty reports, due within [***] after the end of each calendar quarter. Each such royalty report shall disclose the number of Units of Licensed Product
sold, the total Net Sales of such Licensed Product, and the resulting royalties due to LI-COR as a result of either number of Units or Net Sales by Aura and its Affiliates and Sublicensees. Payment of any such
royalties due will accompany such royalty report. If no amounts are due LI-COR for any calendar quarter, the report shall so state. 

4.2    Records and Inspections. Aura shall make and retain, for a period of three (3) years following
the period of each report required by Section 4.1, true and accurate records, files, and books of account containing all the data reasonably required for the full computation and verification of sales and other information required in
Section 4.1. Such books and records will be in accordance with generally accepted accounting principles consistently applied. Subject to 

  
 8

determination that the IRDye 700DX does not conform to the applicable Specifications. If LI-COR disagrees as to whether or not the IRDye 700DX meets the Specifications, the Parties shall submit the IRDye 700DX
in question to an independent third party that has the capability of testing the IRDye 700DX to determine whether or not it complies with applicable Specifications. The losing Party will bear all costs and expenses related to such testing. 

6.7    Safety Stock. LI-COR shall, at all times during the Term, maintain a
minimum safety stock of the IRDye 700DX sufficient to meet at least eighteen (18) months demand based on Aura’s Forecast. 

6.8    Secondary Supplier. In the event that LI-COR fails to supply Aura
with IRDye 700DX meeting the Forecast for a period of six (6) consecutive months, and LI-COR is unable to meet the Forecast after such six (6) consecutive month period (“Supply
Failure”), Aura may secure a secondary supplier to supply Aura’s Forecasted requirements of IRDye 700DX from such secondary supplier for such period that LI-COR is unable to meet
Aura’s Forecasted requirements. LI-COR shall use best efforts to assist Aura in providing Know-How to such secondary supplier necessary to manufacture the IR Dye
700DX. In the event of a Supply Failure, and subject to the terms set forth in this Agreement, LI-COR shall grant to a secondary supplier a non-exclusive royalty-bearing
license under the Licensed Patent and Know-How to make and have made IRDye 700DX on behalf of Aura for the Licensed Product for the Licensed Field in the Territory. Such license shall be limited to the period
of such Supply Failure and shall extend after such Supply Failure, provided, that after such Supply Failure such secondary supplier may supply up to twenty percent (20%) of Aura’s requirements of IR Dye 700DX.

subject to United States laws and regulations controlling the export of compounds, technical data, and other commodities, and that Aura’s rights under this Agreement are contingent on compliance with applicable United States export laws and
