      <div style="font-size: 10pt;">&#160;</div>

      <div style="text-align: justify; font-family: 'Times New Roman'; font-size: 10pt;">On June 20, 2023, the board of directors (the &#8220;Board&#8221;) of Catalyst Biosciences, Inc., a Delaware corporation (the &#8220;Company&#8221; or &#8220;Catalyst&#8221;), declared a dividend of one
        one-thousandth of a share of Series Y Preferred Stock, par value $0.001 per share (&#8220;Series Y Preferred Stock&#8221;), for each outstanding share of the Company&#8217;s common stock, par value $0.001 per share (&#8220;Common Stock&#8221;), to stockholders of record at 5:00
        p.m. Eastern Time on June 30, 2023. The Company has filed a certificate of designation with respect to the Series Y Preferred Stock (the &#8220;Certificate of Designation&#8221;) that sets forth the rights, preferences and limitations of the Series Y Preferred
        Stock, including the following:</div>

      <div style="font-size: 10pt;">&#160;</div>

      <div style="text-align: justify; font-family: 'Times New Roman'; font-size: 10pt;"><span style="font-size: 10pt; font-family: 'Times New Roman'; font-weight: bold; font-style: italic;">General; Transferability</span><span style="font-size: 10pt;">.
          Shares of Series Y Preferred Stock will be uncertificated and represented in book-entry form. No shares of Series Y Preferred Stock may be transferred by the holder thereof except in connection with a transfer by such holder of any shares of
          Common Stock held by such holder, in which case a number of one one-thousandths (1/1,000ths) of a share of Series Y Preferred Stock equal to the number of shares of Common Stock to be transferred by such holder will be automatically transferred
          to the transferee of such shares of Common Stock.</span></div>

      <div style="font-size: 10pt;">&#160;</div>

      <div style="text-align: justify; font-family: 'Times New Roman'; font-size: 10pt;"><span style="font-size: 10pt; font-family: 'Times New Roman'; font-weight: bold; font-style: italic;">Voting Rights</span><span style="font-size: 10pt; font-family: 'Times New Roman'; font-style: italic;">. </span><span style="font-size: 10pt;">Each whole share of Series Y Preferred Stock will entitle the holder thereof to 250,000 votes per share (and, for the avoidance of doubt, each fraction of a share of
          Series Y Preferred Stock will have a ratable number of votes). Thus, each one-thousandth of a share of Series Y Preferred Stock would entitle the holder thereof to 250 votes. The outstanding shares of Series Y Preferred Stock will vote together
          with the outstanding shares of Common Stock of the Company as a single class exclusively with respect to any proposal to adopt an amendment to the Company&#8217;s Fourth Amended and Restated Certificate of Incorporation, as amended (the &#8220;Certificate of
          Incorporation&#8221;), to reclassify the outstanding shares of Common Stock into a smaller number of shares of Common Stock at a ratio specified in or determined in accordance with the terms of such amendment, which proposal may or may not involve a
          reduction in the total authorized Common Stock (the &#8220;Reverse Stock Split&#8221;). The Series Y Preferred Stock will not be entitled to vote on any other matter, except to the extent required under the Delaware General Corporation Law.</span></div>

      <div style="font-size: 10pt;">&#160;</div>

      <div style="text-align: justify; font-family: 'Times New Roman'; font-size: 10pt;">Unless otherwise provided on any applicable proxy or ballot with respect to the voting on the Reverse Stock Split, the vote of each share of Series Y Preferred Stock
        (or fraction thereof) entitled to vote on the Reverse Stock Split will be cast in the same manner as the vote, if any, of the share of Common Stock in respect of which such share of Series Y Preferred Stock (or fraction thereof) was issued as a
        dividend is cast on the Reverse Stock Split, and the proxy or ballot with respect to shares of Common Stock held by any holder on whose behalf such proxy or ballot is submitted will be deemed to include all shares of Series Y Preferred Stock (or
        fraction thereof) held by such holder. Holders of Series Y Preferred Stock will not receive a separate ballot or proxy to cast votes with respect to Series Y Preferred Stock on the Reverse Stock Split or any other matter brought before any meeting
        of stockholders held to vote on the Reverse Stock Split.</div>

          Series Y Preferred Stock will rank (i) senior to the Common Stock and (ii) junior to (A) the Series X Convertible Preferred Stock, par value $0.001 per share, and (B) the CVRs and CVR Payments, in each case, as to any distribution of assets upon
          a liquidation, dissolution or winding up of the Company, whether voluntarily or involuntarily (a &#8220;Dissolution&#8221;). Upon any Dissolution, each holder of outstanding shares of Series Y Preferred Stock will be entitled to be paid out of the assets of
          the Company available for distribution to stockholders, prior and in preference to any distribution to the holders of Common Stock, an amount in cash equal to $0.001 per outstanding share of Series Y Preferred Stock. &#8220;CVRs&#8221; means the contingent
          value rights distributed pursuant to that certain Contingent Value Rights Agreement, dated December 26, 2022, by and between the Company and American Stock Transfer &amp; Trust Company, LLC and &#8220;CVR Payments&#8221; means any amounts paid or to be paid

          Series Y Preferred Stock that are not present in person or by proxy at any meeting of stockholders held to vote on the Reverse Stock Split as of immediately prior to the opening of the polls at such meeting (the &#8220;Initial Redemption Time&#8221;) will
          automatically be redeemed in whole, but not in part, by the Company at the Initial Redemption Time without further action on the part of the Company or the holder of shares of Series Y Preferred Stock (the &#8220;Initial Redemption&#8221;). Any outstanding
          shares of Series Y Preferred Stock that have not been redeemed pursuant to the Initial Redemption will be redeemed in whole, but not in part, (i) if such redemption is ordered by the Board in its sole discretion, automatically and effective on
          such time and date specified by the Board in its sole discretion or (ii) automatically upon the effectiveness of the amendment to the Certificate of Incorporation implementing the Reverse Stock Split.</span></div>
