WHEREAS, as of the date hereof, the Shareholder is the holder of the number and type of shares of Company Common Stock set forth opposite the Shareholder’s name on the signature page hereto (all shares set forth on the signature page, together with any shares of Company Common Stock that are hereafter issued to or otherwise acquired or owned, including upon exercise of Company Options or securities convertible into or exercisable or exchangeable for Company Common Stock, by the Shareholder prior to the termination of this Agreement being referred to herein as the “Subject Shares”); and

WHEREAS, as a condition to its willingness to enter into the Merger Agreement, Yumanity has required that the Shareholder, and as an inducement and in consideration therefor, the Shareholder (in the Shareholder’s capacity as a holder of the Subject Shares) has agreed to, enter into this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth below and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, do hereby agree as follows:

ARTICLE I

VOTING AGREEMENT; GRANT OF PROXY

The Shareholder hereby covenants and agrees that:

1.1. Voting of Subject Shares and Support of Contemplated Transactions. The Shareholder hereby agrees that within ten (10) Business Days after the S-4 Registration Statement is declared effective, the Shareholder shall execute and deliver, or cause to be executed and delivered, to Yumanity, a written consent approving the matters set forth in (a) below, which written consent shall be coupled with an interest and shall be irrevocable. At every meeting of

the shareholders of the Company (“Company Shareholders”), however called, and at every adjournment or postponement thereof (or pursuant to a written consent if Company Shareholders act by written consent in lieu of a meeting), the Shareholder shall, or shall cause the holder of record on any applicable record date to, be present (in person or by proxy) and to vote the Shareholder’s Subject Shares (a) in favor of (i) the approval of and adoption of the Merger Agreement and approval of the Contemplated Transactions, (ii) approval of any proposals to adjourn or postpone the meeting to a later date, if there are not sufficient votes for the adoption of the Merger Agreement and approval of the Contemplated Transactions on the date which such meeting is held and (iii) any other matter necessary to consummate the transactions contemplated by the Merger Agreement that are considered and voted upon by Company Shareholders; and (b) against any Acquisition Proposal.

1.2. No Inconsistent Arrangements. Except as provided hereunder or under the Merger Agreement, the Shareholder shall not, directly or indirectly, (a) create any Encumbrance other than restrictions imposed by applicable Law or pursuant to this Agreement or the governance documents of the Company on any Subject Shares, (b) transfer, sell, assign, gift or otherwise dispose of (collectively, “Transfer”), or enter into any contract with respect to any Transfer of the Subject Shares or any interest therein, (c) grant or permit the grant of any proxy, power of attorney or other authorization in or with respect to the Subject Shares, (d) deposit or permit the deposit of the Subject Shares into a voting trust or enter into a voting agreement or arrangement with respect to the Subject Shares or (e) take any action that would make any representation or warranty of the Shareholder herein untrue or incorrect in any material respect, or have the effect of preventing the Shareholder from performing its obligations hereunder. Notwithstanding the foregoing, (i) the Shareholder may make Transfers of Subject Shares by will, operation of law, or Transfers for estate planning purposes, in which case the Subject Shares shall continue to be bound by this Agreement and provided that each transferee agrees in writing to be bound by the terms and conditions of this Agreement and either the Shareholder or the transferee provides the Company and Yumanity with copies of such agreement promptly upon consummation of any such Transfer and (ii) the Shareholder may take all actions reasonably necessary to consummate the transactions contemplated by the Merger Agreement.

1.3. Documentation and Information. The Shareholder shall permit and hereby authorizes Yumanity and the Company to publish and disclose in all documents and schedules filed with the SEC, and any press release or other disclosure document that Yumanity or the Company reasonably determines to be necessary in connection with the Merger and any transactions contemplated by the Merger Agreement, the Shareholder’s identity and ownership of the Subject Shares and the nature of the Shareholder’s commitments and obligations under this Agreement. The Company is an intended third-party beneficiary of this Section 1.3.

1.4. Irrevocable Proxy. The Shareholder hereby revokes (or agrees to cause to be revoked) any proxies that the Shareholder has heretofore granted with respect to the Subject Shares. The Shareholder hereby irrevocably appoints the Company, and any individual designated in writing by the Company, as attorney-in-fact and proxy for and on behalf of the Shareholder, for and in the name, place and stead of the Shareholder, to: (a) attend any and all meetings of the Company Shareholders, (b) vote, express consent or dissent or issue instructions to the record holder to vote the Shareholder’s Subject Shares in accordance with the provisions

2

of Section 1.1 at any and all meetings of Company Shareholders or in connection with any action sought to be taken by written consent of Company Shareholders without a meeting and (c) grant or withhold, or issue instructions to the record holder to grant or withhold, consistent with the provisions of Section 1.1, all written consents with respect to the Subject Shares at any and all meetings of Company Shareholders or in connection with any action sought to be taken by written consent without a meeting. The Company agrees not to exercise the proxy granted herein for any purpose other than the purposes described in this Agreement. The foregoing proxy: (x) shall be deemed to be a proxy coupled with an interest, is irrevocable (and as such shall survive and not be affected by the death, incapacity, mental illness or insanity of the Shareholder, as applicable) until the termination of this Agreement pursuant to Section 4.2; (y) shall not be terminated by operation of law or upon the occurrence of any other event other than the termination of this Agreement pursuant to Section 4.2; and (z) shall revoke any and all prior proxies or powers of attorney granted by the Shareholder and no subsequent proxy or power of attorney shall be given or written consent executed (and if given or executed, shall not be effective) by the Shareholder with respect thereto. The Shareholder authorizes such attorney and proxy to substitute any other Person to act hereunder, to revoke any substitution and to file this proxy and any substitution or revocation with the Secretary of the Company. The Shareholder hereby affirms that the proxy set forth in this Section 1.4 is given in connection with and granted in consideration of and as an inducement to the Company to enter into the Merger Agreement and that such proxy is given to secure the obligations of the Shareholder under Section 1.1. The proxy set forth in this Section 1.4 is executed and intended to be irrevocable, subject, however, to its automatic termination upon the termination of this Agreement pursuant to Section 4.2.

1.5. No Solicitation of Transactions. The Shareholder shall not, directly or indirectly, through any officer, director, agent or otherwise, (a) solicit, initiate, knowingly encourage, induce or knowingly facilitate the communication, making, submission or announcement of any Acquisition Proposal or Acquisition Inquiry with respect to the Company or take any action that could reasonably be expected to lead to an Acquisition Proposal or Acquisition Inquiry with respect to the Company or (b) engage in discussions or negotiations regarding, or furnish to any person, any nonpublic information with respect to, or otherwise cooperate in any way with respect to, or assist or participate in, or facilitate or encourage, any unsolicited proposal that constitutes, or may reasonably be expected to lead to, an Acquisition Inquiry or Acquisition Proposal with respect to the Company. The Shareholder hereby represents and warrants that it, he or she has read Section 4.5 of the Merger Agreement and agrees not to facilitate or participate in any actions prohibited thereby.
