LICENSE AGREEMENT 
 for

 COMPOSITIONS AND METHODS FOR EXPRESSING OTOFERLIN 

This license agreement (“Agreement”) is made effective October 03, 2019 (“Effective Date”), by and between The Regents of
the University of California, a California public corporation, having its statewide administrative offices at 1111 Franklin Street, 12th Floor, Oakland, California 94607-5200 (“The
Regents”) and acting through its Office of Technology Management, University of California San Francisco (“UCSF”), 600 16th Street, Suite
S-272, San Francisco, CA 94143 and Decibel Therapeutics, a Delaware corporation, having a principal place of business 1325 Boylston Street Suite 500, Boston, Massachusetts 02215 (“Licensee”). 

BACKGROUND 
 A. Certain
inventions, generally characterized as “Compositions and methods for expressing otoferlin” (UC Case No. [**]) (collectively “Invention”), made in the course of research at University of Florida Research Foundation
(“UFRF”) and UCSF and are claimed in Patent Rights as defined below. Invention was made in the course of research at UCSF by Dr. Omar Akil (collectively, the “Inventor”). UCSF and UFRF, each is licensing their interest in
and to Patent Rights separately and independently. 
 B. The development of the Invention was sponsored in part by the National Institutes
of Health and, as a consequence, this license is subject to overriding obligations to the United States Federal Government under 35 U.S.C. §§ 200-212 and applicable regulations including a non-exclusive, non-transferable, irrevocable, paid-up license to practice or have practiced the Invention for or on behalf of the
United States Government throughout the world. 
 C. The development of the Invention was sponsored in part by Hearing Research, Inc. 

D. The Licensee and The Regents have executed a Secrecy Agreement (UC Control No.[**]) with an effective date of [**].

 E. The scope of such rights granted by The Regents is intended to extend to the scope of the
patents and patent applications in Patent Rights, but only to the extent that The Regents has proprietary rights in and to the Valid Claims of such Patent Rights. 

F. Both parties recognize and agree that Earned Royalties are due under this Agreement with respect to products, services and methods and that
such royalties will be paid with respect to both pending patent applications and issued patents, in accordance with the terms and conditions set forth herein. 

G. The Licensee is a “small business firm” as defined in 15 U.S.C. §632.

fifty percent (50%) of the voting rights entitled to elect directors; or (iii) in any country where the local law will not permit foreign equity participation of a majority, ownership or control, directly or indirectly, of the maximum
percentage of such outstanding stock or voting rights permitted by local law. 


  

	1.2	 “Field of Use” means all fields. 



 

	1.3	 “Licensed Method” means any process, art or method the use or practice of which, but for the license
granted in this Agreement, would infringe, or contribute to, or induce the infringement of, any Patent Rights in any country were they issued at the time of the infringing activity in that country. 



 

	1.4	 “Licensed Product(s) “ means any product, including, without limitation, a product for use or used in
practicing a Licensed Method and any product made by practicing a Licensed Method, the manufacture, use, Sale, offer for Sale or import of which, but for the license granted in this Agreement, would infringe, or contribute to, or induce the
infringement of, any Patent Rights in any country were they issued at the time of the infringing activity in that country. 



  
 Page 2 of 29 














	1.5	 “Licensed Service(s)” means any service provided for consideration (whether in cash or any other
form), when such service (i) involves the use of a Licensed Product; or (ii) involves the practice of a Licensed Method. 


  

	1.6	 “Net Sale” means the total amount invoiced (including fair market value of any non-cash consideration) by Licensee or by any Affiliate or Sublicensee on account of Sales of Licensed Product or Licensed Services, after deduction of all the following in accordance with U.S. Generally Accepted
Accounting Principles (“U.S. GAAP”) to the extent applicable to such Sales: 


  

	 	1.6.1	 trade, quantity and cash discounts or rebates, chargebacks, actually allowed or taken; 



 

	 	1.6.2	 allowances or credits given for rejection or for return of previously sold Licensed Product or outdated
Licensed Product; 


  

	 	1.6.3	 amounts repaid or credited by reason of rejection, defects, recalls, or returns or because of chargebacks,

	 	1.6.4	 discounts mandated by, or granted solely to meet the requirements of law, including required chargebacks and
retroactive price reductions required by law; 


  

	 	1.6.5	 bad debts and uncollectible receivables; 



 

	 	1.6.6	 any tax or other governmental charge (including without limitation custom surcharges) borne by and not
reimbursed to the Licensee other than income tax levied on the Sale, transportation or delivery of Licensed Product, and 


  

	 	1.6.7	 any charges for packing, handling, freight, insurance, transportation and duty charges borne by the seller.



 For the purposes of this Agreement, chargebacks, bad debt, uncollectible receivables are considered to be Uncollectible Debts.
“Uncollectible Debts” means amount owed and unpaid to the Licensee, or a Sublicensee for previously Sold Licensed Products, which Licensee or the Sublicensee has attempted to collect, using efforts at least as diligent as those efforts
that Licensee or the Sublicensee (as applicable) uses in attempting to collect other overdue debts, provided that such amounts have been formally designated as such in accordance with Licensee’s or the Sublicensee’s internal accounting
procedures and provided further that such allowance shall not be applicable in the event and to the extent any such designated amounts are ultimately collected. 

  
 Page 3 of 29 













 If Licensee or its Affiliates or Sublicensee makes any sales to any third party in a transaction in a given
country that is not an arms’ length transaction, unless a cash discount within the meaning of this Paragraph 1.6 applies, the Net Sales used to determine the royalties payable to The Regents shall be computed on the basis of the established
average price charged to unrelated third parties in such country. 
  

	1.7	 “Patent Rights” means the Valid Claims of, to the extent assigned to or otherwise obtained by The
Regents, the following United States patents and patent applications:

(Sublicenses). 


  

	1.10	 “Sublicensing Revenues” means amounts (including, without limitation, any licensing or optioning
fees, or license maintenance fees, or milestone payments, and fair market value of any non-cash consideration), received by or payable to the Licensee from any Sublicensee under a sublicense of the
Licensee’s rights under this Agreement, provided that Sublicensing Revenues will not include amounts received by or payable to the Licensee that are reasonably and fairly attributable to any of the following to the extent that each is bona
fide: (a) debt financing of the Licensee, (b) amounts received by the Licensee as the purchase price, at fair market value, for equity securities (including stock 



  
 Page 4 of 29 














	 	
of whatever class or series, and including the purchase price for warrants and the exercise price under such warrants, or as convertible debt, and the like) of the Licensee;

(d) royalty payments on Net Sales; and (e) reimbursement to the Licensee for documented cost of research and/or development activities performed or services provided by the Licensee for the specific Licensed Product, on a going-forward
basis, on the basis of reimbursement of out-of-pocket expenses and/or payments for full-time equivalent (“FTE”) efforts of personnel at or below commercially
reasonable and standard FTE rates for the location of Licensee and the kind of activities and services undertaken by the Licensee for which such reimbursement is made to the Licensee . 


 

	1.11	 “Valid Claim” means a claim of a patent or patent application in any country that (i) has not
expired; (ii) has not been disclaimed; (iii) has not been cancelled or superseded, or if cancelled or superseded, has been reinstated; or (iv) has not been revoked, held invalid, or otherwise declared unenforceable or not allowable by
a tribunal or patent authority of competent jurisdiction over such claim in such country from which no further appeal has or may be taken; and, for any of i-iv above, (v) has not been pending for more than [**] after the date of issuance of the
first office action on any patent application under Patent Rights, on a country-by-country basis. 



2. GRANT 
  

	2.1	 Subject to the limitations and other terms and conditions set forth in this Agreement including the license
granted to the United States Government and those reserved by The Regents set forth in the Background and in Paragraphs 2.2.1 (obligations to the United States Government) and 2.4 (Government Requirements) , The Regents grants to the
Licensee a worldwide, license under all of its rights in and to the Patent Rights to make, have made, use, Sell, offer for Sale and import Licensed Products, to provide Licensed Services, and to practice Licensed Methods, in the United States and in
other countries where The Regents may lawfully grant such licenses, only in the Field of Use. So long as this Agreement is in effect, other than as specified in Section 2.3 (Reservation of Rights), The Regents shall not grant any other licenses
for the Patent Rights. For the avoidance of doubt, The Regents grant under this Article 2 and under this Agreement does not include, (i) UFRF rights to the Invention; and, (ii) UFRF rights under Patent Rights. 



  
 Page 5 of 29 














	2.2	 The license granted in Paragraph 2.1 is subject to the following: 



 

	 	2.2.1	 The obligations to the United States Government under 35 U.S.C. §§
200-212 and all applicable governmental implementing regulations, as amended from time to time, including the obligation to report on the utilization of the Invention as set forth in 37 CFR. § 401.14(h),
and all applicable provisions of any license to the United States Government executed by The Regents; and 


  

	 	2.2.2	 the National Institutes of Health “Principles and Guidelines for Recipients of NIH Research Grants and
Contracts on Obtaining and Disseminating Biomedical Research Resources,” 64 F.R. 72090 (Dec. 23, 1999), as amended from time to time. 


  

	2.3	 Reservation of Rights. The Regents reserves and retains the right (and the rights granted to the
Licensee in this Agreement shall be limited accordingly) to make, use and practice the Invention, and any technology relating to any of the foregoing and to make and use any products and to practice any process that is the subject of the Patent
Rights (and to grant any of the foregoing rights to other educational and non-profit institutions) for educational and research purposes only, and including publication and other communication of any research
results. 


 3. SUBLICENSES 
  

	3.1	 Permitted Sublicensing. The Regents also grants to the Licensee the right to sublicense to third parties
(including to Affiliates) the rights granted to the Licensee hereunder, as long as the Licensee has current rights thereto under this Agreement. Each Sublicensee must be subject to a written sublicense agreement. All sublicenses will include all of
the rights of, and will require the performance of all the obligations due to, The Regents (and, if applicable, the United States Government and other sponsors), other than those rights and obligations specified in Article 5 (License Issue Fee),
Article 6 (License Maintenance Fee) and Paragraph 8.3 (Minimum Annual Royalty) and Paragraphs 18.3 and 18.4 (reimbursement of Patent Prosecution Costs). For the purposes of this Agreement, the




  
 Page 6 of 29 














	 	
operations of all Sublicensees shall be deemed to be the operations of the Licensee, for which the Licensee shall be responsible. In the event the Licensee is assigned or otherwise acquires a
license to the Patent Rights from UFRF, the Licensee shall not separately grant a sublicense to any third party under its UFRF rights without concurrently granting a sublicense under The Regents’ rights on the terms and conditions described in
this Article 3. 

  

	3.2	 Sublicensee of a Sublicensee. For the purpose of this Agreement, all sublicensees of Sublicensees are
(i) considered as Sublicensees of the Regents; and (ii) shall be subject to all the terms and conditions applicable to a Sublicensee under this Agreement; and (iii) shall pay all royalty and fees applicable to a Sublicensee under this
Agreement. Licensee shall remain fully liable to the Regents for all acts and obligations of such Sublicensee and, acts of such Sublicensee shall be considered acts of the Licensee. 



 

	3.3	 Sublicense Requirements. The Licensee shall provide The Regents with a copy of each sublicense issued
within [**] of execution of such sublicense or sublicense amendment; collect and guarantee payment of all payments due The Regents from Sublicensees; and summarize and deliver all reports due The Regents from Sublicensees. 



 

	3.4	 Mandatory Sublicensing. If Licensee is unable or unwilling to serve or develop a potential market or
market territory for which there is a company willing to be a Sublicensee, Licensee will, at The Regents’ request, negotiate in good faith with any such company. The Regents would like licensees to address unmet needs, such as those of
neglected patient populations or geographic areas, giving particular attention to improved therapeutics, diagnostics and agricultural technologies for the developing world. 



 

	3.5	 License Termination. Upon termination of this Agreement for any reason, each sublicense granted by
Licensee to a Sublicensee shall remain in effect as a direct license from The Regents to the Sublicensee (each a “New License Agreement”), for the scope of the license granted to such Sublicensee, on the same terms as this Agreement
(taking into account any difference in license scope, territory, and duration of sublicense grant), provided that the Sublicensee is not at the time of such termination in breach of its sublicense agreement, is not at the time of such termination an
opposing party in any legal proceeding involving The Regents, and that the financial terms of each New Licensee Agreement shall be identical to the corresponding financial terms of this Agreement. In




  
 Page 7 of 29 














	 	
the event of termination of this Agreement and if The Regents shall grant a direct license to any Sublicensee pursuant to the preceding sentence, The Regents will not be bound by any grant of
rights broader than or will not be required to perform any obligation other than those rights and obligations contained in this Agreement. The Regents and the Sublicensee will modify each such New License Agreement to include all of the rights of
The Regents (and [**], and, if applicable, the United States Government and other sponsors) that are contained in this Agreement. Notwithstanding the foregoing, each Sublicensee’s right to enter into a New License Agreement shall only be
available to the extent (i) Licensee has provided The Regents with a copy of the sublicense agreement granting the sublicense to such Sublicensee as required under Paragraph 3.3 and with all terms relating to the rights and obligations under
this Agreement left unredacted, (ii) such Sublicensee notifies The Regents within [**] after the termination of this Agreement that it wishes to enter into a New License Agreement, (iii) Sublicensee pays to The Regents its pro rata share
of any unreimbursed patent expenses during the negotiation of the New License Agreement within [**] of the mailing date of the invoice for such expenses, and (iv) the duties of The Regents under the New License Agreement will not be greater
than the duties of The Regents under this Agreement and (v) there is no outstanding or ongoing material breach of such sublicense by such Sublicensee which remains uncured. The terms in this Paragraph 3.5 are applicable only to sublicenses
granted by Licensee and are not applicable to any sublicenses granted by a Sublicensee. 

 4. PAYMENT TERMS 

 

	4.1	 Payment Obligations. Paragraphs 1.3, 1.4, 1.5, and 1.7 define Licensed Method, Licensed Product,
Licensed Service and Patent Rights, so that Earned Royalties are payable on products and methods covered by both pending patent applications and issued patents. Earned Royalties will accrue in each country for the duration of Patent Rights in that
country and will be payable to The Regents when Licensed Products or Licensed Services are invoiced, or if not invoiced, when delivered or otherwise exploited by the Licensee or Sublicensee in a manner constituting a Net Sale as defined in Paragraph
1.6. Sublicense Fees with respect to any Sublicensing Revenue shall accrue to The Regents within [**] of the date that such Sublicensing Revenue is due to the Licensee. 



  
 Page 8 of 29 














	4.2	 Schedule. The Licensee will pay to The Regents all Earned Royalties, Sublicense Fees and other
consideration payable to The Regents quarterly on or before [**] (for the calendar quarter ending December 31), [**] (for the calendar quarter ending March 31), [**] (for the calendar quarter ending June 30) and [**] (for the calendar quarter ending
September 30) of each calendar year. Each payment will be for Earned Royalties, Sublicense Fees and other consideration which has accrued within the Licensee’s most recently completed calendar quarter. 



 

	4.3	 Currency. All consideration due The Regents will be payable and will be made in United States dollars by
check payable to “The Regents of the University of California” or by wire transfer to an account designated by The Regents. The Licensee is responsible for all bank or other transfer charges. When Licensed Products or Licensed Services are
Sold for monies other than United States dollars, the Earned Royalties and other consideration will first be determined in the foreign currency of the country in which such Licensed Products or Licensed Services were Sold and then converted into
equivalent United States dollars. The exchange rate will be the average exchange rate quoted in the The Wall Street Journal during the last [**] of the reporting period. 



 

	4.4	 Taxes. Sublicense Fees and Earned Royalties on Net Sales of Licensed Products or Licensed Services and
other consideration accrued in, any country outside the United States may not be reduced by any taxes, fees or other charges imposed by the government of such country, except those taxes, fees and charges allowed under the provisions of Paragraph
1.6 (Net Sales). 


  

	4.5	 Accrual. In the event that any patent or claim thereof included within the Patent Rights is held invalid
in a final decision by a court of competent jurisdiction and last resort and from which no appeal has or can be taken, then all obligation to pay royalties based on that patent or claim or any claim patentably indistinct therefrom will cease as of
the date of final decision. The Licensee will not, however, be relieved from paying any royalties that accrued before such final decision and the Licensee shall be obligated to pay the full amount of royalties due hereunder to the extent that The
Regents licenses one or more Valid Claims within the Patent Rights to the Licensee with respect to Licensed Products or Licensed Services. 



  
 Page 9 of 29 














	4.6	 Late Payments. In the event that royalties, fees, reimbursements for Patent Prosecution Costs or other
monies owed to The Regents are not received by The Regents when due, the Licensee will pay to The Regents interest at a rate of [**] percent ([**]%) simple interest per annum. Such interest will be calculated from the date payment was due until
actually received by The Regents. Such accrual of interest will be in addition to and not in lieu of, enforcement of any other rights of The Regents due to such late payment. 



5. LICENSE ISSUE FEE 
  

	5.1	 The Licensee will pay to The Regents a license issue fee of [**] dollars ($[**]) within [**] of the
Effective Date and [**] dollars ($[**]) within [**] of issuance of the first patent under Patent Rights in any jurisdiction. This fee is non-refundable, non-cancelable and is not an advance or otherwise
creditable against any royalties or other payments required to be paid under the terms of this Agreement. 


 6. LICENSE
MAINTENANCE FEE 
  

	6.1	 Subject to Paragraph 6.2, the Licensee shall also pay to The Regents a license maintenance fee within [**] of
the one-year anniversary of the Effective Date and within [**] of each subsequent anniversary of the Effective Date in an amount equal to: 



 

	 	6.1.1	 [**] dollars ($[**]) prior to issuance of the first patent under Patent Rights in any jurisdiction; or



  

	 	6.1.2	 [**] dollars ($[**]) after issuance of the first patent under Patent Rights in any jurisdiction; or



  

	6.2	 The license maintenance fee is not due on any anniversary of the Effective Date if on that date, the Licensee
is Selling or otherwise exploiting Licensed Products or Licensed Services and is paying an Earned Royalty to The Regents on the Net Sales of such Licensed Product or Licensed Service. The license maintenance fee is
non-refundable and is not an advance or otherwise creditable against any royalties or other payments required to be paid under the terms of this Agreement. 



  
 Page 10 of 29 













 7. PAYMENTS ON SUBLICENSES 

 

	7.1	 The Licensee will pay to The Regents the following non-refundable and non-creditable sublicense fees (“Sublicense Fees”) of all Sublicensing Revenues: 


  

	 	7.1.1	 [**] percent ([**]%) of all Sublicensing Revenues [**]; and, 



 

	 	7.1.2	 [**] percent ([**]%) of all Sublicensing Revenues [**]; and, 



 

	 	7.1.3	 [**] percent ([**]%) of all Sublicensing Revenues [**]; and, 



 

	 	7.1.4	 [**] percent ([**]%) of all Sublicensing Revenues [**]. 



8. EARNED ROYALTIES AND MINIMUM ANNUAL ROYALTIES 
  

	8.1	 Earned Royalty. The Licensee will pay to The Regents an Earned Royalty of [**] percent ([**]%) of the
Net Sales of Licensed Product or Licensed Service by the Licensee, Sublicensee, or any Affiliate for all aggregate Net Sales (“Earned Royalty”). Any payments received for Earned Royalty will be
non-refundable and non-creditable towards any other payment due to The Regents. In case of documented overpayment, if Licensee gives notice to The Regents within [**] of
The Regents’ receipt of such payment, such overpayment can be credited against future royalty payments. 


  

	8.2	 Royalty Offset. In the event Licensee determines it is necessary for the Licensee to obtain a license to
patent rights of one or more third parties, that is/are not an Affiliate, in order to practice Licensed Methods and/or make, have made, use, sell, offer to sell or import Licensed Products, and Licensee is required to pay a royalty to both The
Regents under this license agreement and the unaffiliated third parties under a separate license agreement in order to practice Licensed Methods and/or to make, have made, use, sell, offer to sell or import Licensed Products, then if the combined
royalty due to The Regents and such third party(ies) exceeds [**] percent ([**]%) then the Earned Royalty percentage due to The Regents hereunder will be reduced by the amount determined by the following formula: [**], where “A” equals the
total royalty burden percentage due for the Licensed Product (including the Earned Royalty due to The Regents and any royalty due to one or more third parties, that is/are not an Affiliate,), and “B” equals the total number of licenses,
including this license and such licenses from all third parties, that is/are not Affiliate(s), provided that in no event will the Earned Royalty due to The Regents be less than [**] percent ([**]%) of the Net Sales of Licensed Product or Licensed
Service by the Licensee, Sublicensee, or any Affiliate for all aggregate Net Sales, in any given payment period. The royalty offset under this Paragraph 8.2 does not apply to any licenses obtained by the Licensee for UFRF rights in the
Invention. 



  
 Page 11 of 29 














	8.3	 Minimum Annual Royalty. The Licensee will also pay to The Regents a minimum annual royalty of [**]
dollars ($[**]) for the life of Patent Rights, beginning with the year of the first Sale of Licensed Product or Licensed Service. The minimum annual royalty will be paid to The Regents by [**] of each year and will be credited against the Earned
Royalty due for the calendar year in which the minimum payment was made. Licensee’s obligation to pay the minimum annual royalty will be pro-rated for the number of months remaining in the calendar year
when Sales commence and will be due the following [**] (along with the minimum annual royalty payment for that year), to allow for crediting of the pro-rated year’s Earned Royalties.



 9. MILESTONE PAYMENTS 
  

	9.1	 With respect to each Licensed Product and each Licensed Service, the Licensee will pay to The Regents the
following non-refundable, non-creditable amounts: 


  

	 	9.1.1	 [**] dollars ($[**]) upon the [**]; and, 



 

	 	9.1.2	 [**] dollars ($[**]) upon [**]; and, 



 

	 	9.1.3	 [**] dollars ($[**]) milestone payable the first time annual net sales exceed [**] dollars ($[**]); and,



  

	 	9.1.4	 [**] dollars ($[**]) payable the first time annual net sales exceed [**] dollars ($[**]); and,



  

	 	9.1.5	 [**] dollars ($[**]) when cumulative net sales exceed [**] dollars ($[**]); and, 



 

	 	9.1.6	 [**] dollars ($[**]) when cumulative net sales exceed [**] dollars ($[**]). 



 

	9.2	 For the avoidance of doubt, each of the milestone payments set forth in Paragraphs 9.1.1 through 9.1.6 will be
payable with respect to each Licensed Product and each Licensed Service and regardless of whether the applicable milestone event has been achieved by the Licensee, Sublicensee, or any Affiliate. 



 

	9.3	 All milestone payments set forth in Paragraphs 9.1.1 through 9.1.6 are due to The Regents within [**] of the
occurrence of the applicable milestone event. 



  
 Page 12 of 29 













 10. DUE DILIGENCE

Products or Licensed Services are manufactured, used, Sold, offered for Sale or imported. 


  

	10.3	 The Licensee will: 


  

	 	10.3.1	 [**] for a Licensed Product by [**];

	 	10.3.4	 [**] such Licensed Product [**]; and 



 

	 	10.3.5	 [**]. 


  

	10.4	 The Regents recognizes that there are uncertainties associated with the development of therapeutic products and
the regulatory process required by the FDA (and foreign regulatory authorities that are equivalent to the FDA), and that it may be necessary from time to time to amend the milestones under Paragraphs 10.3.1 through 10.3.5. Accordingly, The Regents
agrees to extend each such milestone under Paragraphs 10.3.1 through 10.3.5 for up to [**] provided that Licensee can demonstrate to The Regents its diligent efforts with supporting documentation, at no cost to the Licensee for the first extension.
Additional [**] extensions are available for any milestone provided that Licensee can continue to demonstrate its diligent efforts with supporting documentation and pays an additional extension fee of [**] dollars ($[**]). Each [**] extension will
automatically extend all remaining milestones in Paragraphs 10.3.1 through 10.3.5 by [**]. 


  

	10.5	 If the Licensee is unable to perform any of the above provisions, then The Regents has the right and option to
grant additional commercial licenses to the Patent Rights and/or revoke Licensee’s right to sublicense Patent Rights. This right, if exercised by The Regents, supersedes the rights granted in Article 2 (Grant) and Article 3 (Sublicenses).

	16.2	 Except as expressly set forth in this Agreement, this license and the associated Invention, Patent Rights,
Licensed Products, Licensed Services and Licensed Methods provided by The Regents WITHOUT WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR ANY OTHER WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. THE REGENTS MAKES NO EXPRESS OR IMPLIED

CAUSES OF ACTION OF ANY KIND (INCLUDING TORT, CONTRACT, NEGLIGENCE, STRICT LIABILITY AND BREACH OF WARRANTY) EVEN IF THE REGENTS HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 



18. PATENT PROSECUTION AND MAINTENANCE 
  

	18.1	 Patent Prosecution. UCSF and UFRF entered into a patent management agreement on July 5, 2019,
(“Patent Management Agreement”) for the management of matters related to the jointly owned Invention and Patent Rights thereto. Licensee has read and understood the Patent Management Agreement, which is attached in Appendix A. In the
event, Licensee wants to change the patent strategy or patent scope or patent claims, Licensee agrees to be transparent in their communication and promptly discuss with The Regents any such strategy. If aforementioned change in strategy by Licensee
may result in change in inventor-ship of Patent Rights as per patent law, then Licensee shall bring this to The Regents attention immediately. Licensee is committed to engaging in good faith patent strategies and shall diligently work with The
Regents for the same. As long as the Licensee has paid patent costs as provided for in this Article 18, The Regents shall diligently 



  
 Page 18 of 29 














	 	
endeavor to prosecute and maintain the United States and foreign patents comprising Regents’ Patent Rights using counsel of its choice. The Regents will provide the Licensee with copies of
all relevant documentation so that the Licensee will be informed of the continuing prosecution and may comment upon such documentation sufficiently in advance of any initial deadline for filing a response, provided, however, that if the Licensee has
not commented upon such documentation in a reasonable time for The Regents to sufficiently consider the Licensee’s comments prior to a deadline with the relevant government patent office, or The Regents must act to preserve the Patent Rights,
The Regents will be free to respond without consideration of the Licensee’s comments, if any. The Licensee agrees to keep this documentation confidential. The Regents’ counsel will take instructions only from The Regents, and all patents
and patent applications under this Agreement will be assigned solely to The Regents. The Regents shall use all reasonable efforts to amend any patent application to include claims reasonably requested by the Licensee to protect the products
contemplated to be sold under this Agreement and to file and prosecute patents in foreign countries indicated by and paid for by Licensee. 

  

	18.2	 Patent Term. The Licensee shall apply for an extension of the term of any patent included within
Regents’ Patent Rights if appropriate under the Drug Price Competition and Patent Term Restoration Act of 1984 and/or European, Japanese and other foreign counterparts of this Law. The Licensee shall prepare all documents, and The Regents
agrees to execute the documents and to take additional action as the Licensee reasonably requests in connection therewith. 


  

	18.3	 Costs. The Licensee will bear all costs of preparing, filing, prosecuting and maintaining all United
States and foreign patent applications contemplated by this Agreement (“Patent Prosecution Costs”). Patent Prosecution Costs billed by The Regents’ counsel will be rebilled to the Licensee and are due within [**] of rebilling by The
Regents. These Patent Prosecution Costs will include, without limitation, patent prosecution costs for the Invention incurred by The Regents prior to the execution of this Agreement and any patent prosecution costs that may be incurred for
patentability opinions, re-examination, re-issue, interferences, oppositions or inventorship determinations. Prior Patent Prosecution Costs will be due upon execution of
this Agreement and billing by The Regents. 



  
 Page 19 of 29 














	18.4	 Effects of Termination. The Licensee will be obligated to pay any agreed-upon Patent Prosecution Costs
incurred during the [**] period after receipt by either party of a Notice of Termination, even if the invoices for such Patent Prosecution Costs are received by the Licensee after the end of the [**] period following receipt of a Notice of
Termination. The Licensee may terminate its obligation to pay Patent Prosecution Costs with respect to any given patent application or patent under Patent Rights in any or all designated countries upon [**] written notice to The Regents. The Regents
may continue prosecution and/or maintenance of such application(s) or patent(s), and applications in foreign countries where Licensee has elected not to file, at its sole discretion and expense, provided, however, that the Licensee will have no
further right or licenses thereunder. Non-payment of Patent Prosecution Costs may be deemed by The Regents as an election by the Licensee not to maintain such application(s) or patent(s).



 19. PATENT MARKING 
  

	19.1	 The Licensee will mark all Licensed Products made, used or Sold under the terms of this Agreement or their
containers in accordance with the applicable patent marking laws. 


 20. PATENT INFRINGEMENT 

 

	20.1	 Infringement Notice. In the event that The Regents (to the knowledge of the licensing professional
responsible for the administration of this Agreement) or the Licensee learns of infringement of potential commercial significance of any patent licensed under this Agreement, the knowledgeable party will provide the other (i) with written
notice of such infringement and (ii) with any evidence of such infringement available to it (the “Infringement Notice”). During the period in which, and in the jurisdiction where, the Licensee has rights under this Agreement, the
Licensee shall not notify a possible infringer of infringement or put such infringer on notice of the existence of any Patent Rights without first consulting with The Regents. Both The Regents and the Licensee will use their diligent efforts to
cooperate with each other to terminate such infringement without litigation. 


  

	20.2	 Company Suit and Joining. At Licensee’s discretion and to the extent permitted by law, Licensee may
institute suit for patent infringement against the infringer if infringing 



  
 Page 20 of 29 














	 	
activity of potential commercial significance occurs. The Regents may voluntarily join such suit, but may not otherwise commence suit against the infringer for the acts of infringement that are
the subject of the Licensee’s suit or any judgment rendered in that suit. The Licensee may not join The Regents as a party in a suit initiated by the Licensee without The Regents’ prior written consent. If The Regents joins a suit
initiated by the Licensee, then the Licensee will pay any costs incurred by The Regents arising out of such suit, including but not limited to, any legal fees of counsel that The Regents selects and retains to represent it in the suit.


  

	20.3	 Regents’ Suit. If, within [**] following the date the Infringement Notice takes effect or for such
other time as the Parties mutually agree, infringing activity of potential commercial significance by the infringer has not been abated and if the Licensee has not brought suit against the infringer, then The Regents may institute suit for patent
infringement against the infringer. If The Regents institutes such suit, then the Licensee may not join such suit without The Regents’ consent and may not thereafter commence suit against the infringer for the acts of infringement that are the
subject of The Regents’ suit or any judgment rendered in that suit. 


  

	20.4	 Infringement Notice. Notwithstanding anything to the contrary in this Agreement, in the event that the
infringement or potential infringement pertains to an issued patent included within the Patent Rights and written notice is given under the Drug Price Competition and Patent Term Restoration Act of 1984 (and/or foreign counterparts of this Law),
then the party in receipt of such notice under the Act (in the case of The Regents to the extent of the actual knowledge of the licensing officer responsible for the administration of this Agreement) shall provide the Infringement Notice to the
other party promptly. If the time period is such that the Licensee will lose the right to pursue legal remedy for infringement by not notifying a third party or by not filing suit, the notification period and the time period to file suit will be
accelerated to within [**] of the date of such notice under the Act to either party. 


  

	20.5	 Recovery. Any recovery or settlement received in connection with any suit will first be shared by The
Regents and the Licensee equally to cover any litigation costs each incurred and next shall be paid to The Regents or the Licensee to cover any litigation costs it incurred in excess of the litigation costs of the other. In any suit initiated by
Licensee, any 



  
 Page 21 of 29 














	 	
recovery in excess of litigation costs will be shared between Licensee and The Regents as follows: (a) for any recovery other than amounts paid for willful infringement The Regents will
receive [**] percent ([**]%) of the recovery; and (b) for any recovery for willful infringement, The Regents will receive [**] percent ([**]%) of the recovery. In any suit initiated by The Regents, any recovery in excess of litigation costs
will belong to The Regents. The Regents and the Licensee agree to be bound by all determinations of patent infringement, validity and enforceability (but no other issue) resolved by any adjudicated judgment in a suit brought in compliance with this
Article 20 (Patent Infringement). 

  

	20.6	 Sublicenses. Any agreement made by the Licensee for purposes of settling litigation or other dispute
shall comply with the requirements of Article 3 (Sublicenses) of this Agreement. 


  

	20.7	 Cooperation. Each party will cooperate with the other in litigation proceedings instituted hereunder but
at the expense of the party who initiated the suit (unless such suit is being jointly prosecuted by the parties). 


  

	20.8	 Control. Any litigation proceedings will be controlled by the party bringing the suit, except that The
Regents may be represented by counsel of its choice in any suit brought by the Licensee. 


 21. INDEMNIFICATION 

 

	21.1	 Indemnification. The Licensee will, and will require its Sublicensees to, indemnify, hold harmless and
defend The Regents, the sponsors of the research that led to the Invention, and the inventors of any invention claimed in patents or patent applications under Patent Rights (including the Licensed Products, Licensed Services and Licensed Methods
contemplated thereunder) and their employers, and the officers, employees and agents of any of the foregoing, against any and all claims, suits, losses, damage, costs, fees and expenses resulting from, or arising out of, the exercise of this license
or any sublicense. This indemnification will include, but not be limited to, any product liability. If The Regents believe that there will be a conflict of interest or it will not otherwise be adequately represented by counsel chosen by the Licensee
to defend The Regents in accordance with this Paragraph 21.1, then The Regents may retain counsel of its choice to represent it and the Licensee will pay all expenses for such representation. 



  
 Page 22 of 29 














	21.2	 Insurance. The Licensee, at its sole cost and expense, will insure its activities in connection with any
work performed hereunder and will obtain, keep in force, and maintain the following insurance: 


  

	 	21.2.1	 Commercial Form General Liability Insurance (contractual liability included) with limits as follows:



  

					
	 Each Occurrence
	  	$	[	**] 
	 Personal and Advertising Injury
	  	$	[	**] 
	 General Aggregate (commercial form only)
	  	$	[	**] 

 If the above insurance is written on a claims-made form, it shall continue for [**] following termination or
expiration of this Agreement. The insurance shall have a retroactive date of placement prior to or coinciding with the Effective Date of this Agreement; and 
  

	 	21.2.2	 Worker’s Compensation as legally required in the jurisdiction in which the Licensee is doing business.



 The coverage and limits above will not in any way limit the Licensee’s liability under this Article 21
(Indemnification.) 
  

	21.3	 Certificates. After the execution of this Agreement, and at the request of The Regents, the Licensee
will furnish The Regents with certificates of insurance evidencing compliance with all requirements. Such certificates will: indicate The Regents as an additional insured(s) under the coverage described above in Paragraph 21.2 (Insurance); and
include a provision that the coverage will be primary and will not participate with, nor will be excess over, any valid and collectable insurance or program of self-insurance maintained by The Regents. 



 

	21.4	 Notification. The Regents will promptly notify the Licensee in writing of any claim or suit brought
against The Regents for which The Regents intends to invoke the provisions of this Article 21 (Indemnification). The Licensee will keep The Regents informed of its defense of any claims pursuant to this Article 21 (Indemnification).

 28. CONFIDENTIALITY

  

	28.1	 Confidential Information. The Licensee and The Regents will treat and maintain the other party’s
proprietary business, patent prosecution, software, engineering drawings, process and technical information and other proprietary information, including the negotiated terms of this Agreement and any progress reports and royalty reports and any
sublicense agreement issued pursuant to this Agreement (“Proprietary Information”) in confidence using at least the same degree of care as the receiving party uses to protect its own proprietary information of a like nature from the date
of disclosure until [**] after the termination or expiration of this Agreement. Proprietary Information can be written, oral, or both. This confidentiality obligation will apply to the information defined as “Confidential Information”
under the Secrecy Agreement and such Confidential Information will be treated as Proprietary Information hereunder.

 Page 26 of 29 














	 	
sublicensees, provided that such parties are bound by a like duty of confidentiality as that found in this Article 28 (Confidentiality). Notwithstanding anything to the contrary contained in this
Agreement, The Regents may release this Agreement, including any terms contained herein and information regarding payments or other income received in connection with this Agreement to the inventors, senior administrative officials employed by The
Regents and individual Regents upon their request. If such release is made, then The Regents will request that such terms be kept in confidence in accordance with the provisions of this Article 20 (Confidentiality). In addition, notwithstanding

(Sublicenses) and related definitions to such third party, but will not disclose the name of the Licensee unless the Licensee has already made such disclosure publicly. 


 

	28.3	 Limitations. Nothing contained herein will restrict or impair, in any way, the right of the Licensee or
The Regents to use or disclose any Proprietary Information: 


  

	 	28.3.1	 that recipient can demonstrate by written records was previously known to it prior to its disclosure by the
disclosing party; 


  

	 	28.3.2	 that recipient can demonstrate by written records is now, or becomes in the future, public knowledge other than
through acts or omissions of recipient; 


  

	 	28.3.3	 that recipient can demonstrate by written records was obtained lawfully and without restrictions on the
recipient from sources independent of the disclosing party; and 


  

	 	28.3.4	 that The Regents is required to disclose pursuant to the California Public Records Act or other applicable law.



 The Licensee or The Regents also may disclose Proprietary Information that is required to be disclosed (i) to a
