Explanation of Responses:

( 1 )Twenty-five percent of the shares subject to the Stock Option vests on the first anniversary of the vesting commencement date, and the remainder vests in 36 equal monthly installments thereafter for the following three years. ( 2 )Received pursuant to the Business Combination Agreement (the "BCA"), dated April 15, 2021, by and among the Issuer (fka "Consonance-HFW Acquisition Corp"), Perseverance Merger Sub Inc. ("Merger Sub"), and Surrozen, Inc. (the "Original Surrozen"). Under the terms of the BCA, among other things, Merger Sub merged with and into the Original Surrozen, with Original Surrozen surviving as a wholly-owned subsidiary of the Issuer (the "Business Combination"), the Original Surrozen changed its name to Surrozen Operating, Inc., and the Issuer changed its name to Surrozen, Inc. In addition, per the terms of the BCA, each share and equity award of the Original Surrozen outstanding as of effective time of the Business Combination was exchanged for shares of the Issuer's Common Stock or comparable equity awards that are settled or are exercisable for shares of the Issuer's Common Stock, as applicable, at the exchange ratio of 0.175648535. ( 3 )This amendment is being filed to correct a typographical error in the exercise prices of the Stock Options which were incorrectly reported on the original filed Form 3. ( 4 )1/48th of the shares subject to the Stock Option vests on each monthly anniversary of the vesting commencement date over a four-year period.
