PAGE 5 OF 26

S16-362:MW EXCLUSIVE LICENSE AGREEMENT 6/6/2018

terminated, unless the sublicensee elects for its sublicense to terminate upon the termination of this Agreement. If the sublicensee is a spin-out from Surrozen, Surrozen must guarantee the sublicensee’s performance with respect to the payment of Stanford’s share of Sublicense royalties.

4.4 Litigation by Sublicensee. Any Sublicense and Further Sublicense must include the following clauses:

(A) In the event sublicensee brings an action seeking to invalidate any Licensed Patent:

(1) sublicensee will [****] the payment paid to Surrozen during the pendency of such action. Moreover, should the outcome of such action determine that any claim of a patent challenged by the sublicensee is both valid and infringed by a Licensed Product, sublicensee will pay [****] the payment paid under the original Sublicense;

(2) sublicensee will have no right to recoup any royalties paid before or during the period challenge;

(3) any dispute regarding the validity of any Licensed Patent shall be litigated in the courts located in Santa Clara County, and the parties agree not to challenge personal jurisdiction in that forum; and

Each Sublicense and Further Sublicense may be redacted for information not necessary to determine compliance with this Agreement. Beginning with the first Sublicense, [****].

4.6 Sublicensing Fee. For each third party that has entered into a Sublicense with Surrozen, Surrozen will pay [****] to Stanford (each, a

PAGE 6 OF 26

S16-362:MW EXCLUSIVE LICENSE AGREEMENT 6/6/2018

“Sublicense Fee”). For avoidance of doubt, no such payment shall be made on the basis of Surrozen entering into an agreement with a third party performing activities on behalf Surrozen, such as a contract research organization, clinical trial site, or distributor.

4.7 Royalty-Free Sublicenses. If Surrozen pays all royalties due Stanford from a sublicensee’s Net Sales, Surrozen may grant that sublicensee a royalty-free or non-cash:

(A) Sublicense or

Surrozen will ensure all obligations of these provisions are met.

6. DILIGENCE

6.1 Milestones. Because the invention is not yet commercially viable as of the Effective Date, Surrozen, directly or through its Affiliates, sublicensees or partners and/or its or their contractors, will use commercially reasonable efforts to develop, manufacture and sell a Licensed Product. In addition, Surrozen, directly or through its Affiliates, sublicensees or partners and/or its or their contractors, will meet the milestones shown on the attached Exhibit A.

Stanford agrees to grant reasonable extensions to the target dates of any applicable milestone and the subsequent milestones (without payment) if Surrozen’s failure to meet the applicable milestones is due to [****]. If any diligence milestone is extended, all subsequent milestones also shall be extended.

6.2 Progress Report. By [****] of each year, Surrozen will submit a written annual report to Stanford covering the preceding calendar year. The report will include information sufficient to enable Stanford to satisfy reporting requirements of the U.S. Government and for Stanford to ascertain progress by Surrozen toward meeting this Agreement’s diligence requirements. Each report will describe, where relevant: Surrozen’s progress toward commercialization of Licensed Product, [****]. For the purpose of facilitating Stanford’s accounting practices, including with respect to payments made to its inventors of the Licensed Patents, Surrozen will specifically identify each claim of a Licensed Patent that covers each Licensed Product.

S16-362:MW EXCLUSIVE LICENSE AGREEMENT 6/6/2018

(E) The parties acknowledge that Stanford participated in Surrozen’s Series A preferred stock financing prior to the date of this Agreement, and in connection therewith, Stanford became a party to that certain Investors’ Rights Agreement, dated [****], among Surrozen, Stanford and certain other stockholders of Surrozen (as it may be amended from time to time, the “Rights Agreement”), pursuant to which Stanford has the right to participate in future financings of Surrozen on the terms set forth in the Rights Agreement. Therefore, notwithstanding anything to the contrary in this Agreement, the parties acknowledge and agree that a Termination Event has occurred resulting in the termination of Stanford’s Participation Right hereunder as described in Section 7.2(B). For the avoidance of doubt, Section 7.2 of this Agreement is not applicable (other than, in each case, the definitions set forth in Section 7.2(A)(1)-(6)) and Stanford shall have no rights with respect to, and Surrozen shall have no obligations to Stanford under, Section 7.2 of this Agreement (other than, in each case, the definitions set forth in Section 7.2(A)(1) (6).

For example:

(A) if Surrozen pays Stanford a $10 maintenance payment for year Y, and according to Section 7.6 $15 in earned royalties are due Stanford for Net Sales in year Y, Surrozen will only need to pay Stanford an additional $5 for that year’s earned royalties.

(B) if Surrozen pays Stanford a $10 maintenance payment for year Y, and according to Section 7.6 $3 in earned royalties are due Stanford for Net Sales in year Y, Surrozen will not need to pay Stanford any earned royalty payment for that year. Surrozen will not be able to offset the remaining $7 against a future year’s earned royalites.

7.9 Obligation to Pay Royalties. A royalty is due Stanford under this Agreement for any activity conducted under the licenses granted. For convenience’s sake, the amount of that royalty is calculated using Net Sales.
