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 Stockholder hereby covenants and agrees that: 1.1. Voting of Subject Shares. The Stockholder agrees that at every meeting of the holders of capital stock of Caladrius (the “Caladrius Stockholders”), however called, and at every adjournment or postponement thereof (or pursuant to a written consent if the Caladrius Stockholders act by written consent in lieu of a meeting), the Stockholder shall, or shall cause the holder of record on any applicable record date to, be present (in person or by proxy) and to vote (or cause to be voted) the Stockholder’s Subject Shares (a) in favor of (i) the approval and adoption of the Merger Agreement, (ii) the approval of the Contemplated Transactions, including the issuance of Common Stock pursuant to the Merger Agreement, (iii) if deemed necessary, the adoption of an amendment to Caladrius’s certificate of incorporation to effect the Caladrius Reverse Stock Split, (iv) the adoption of an amendment to Caladrius’s certificate of incorporation to change the name of Caladrius, (v) any proposal to adjourn or postpone the meeting to a later date, if there are not sufficient votes for the approval of the Merger Agreement and the Contemplated Transactions, including the issuance of Common Stock pursuant to the Merger Agreement on the date on which such meeting is held, and (vi) any other proposal included in the Proxy Statement in connection with, or related to, the consummation of the Merger for which the Caladrius Board has recommended that the Caladrius Stockholders vote in favor; and (b) against any competing Acquisition Proposal with respect to Caladrius.

1.2. No Inconsistent Arrangements. Except as expressly permitted or required hereunder or under the Merger Agreement, the Stockholder agrees not to, directly or indirectly, (a) create any Encumbrance other than restrictions imposed by applicable Law or pursuant to this Agreement 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 Stockholder herein untrue or incorrect in any material respect, or have the effect of preventing the Stockholder from performing the Stockholder’s obligations hereunder. Notwithstanding the foregoing, (x) the Stockholder may make Transfers of the Subject Shares (i) by will, operation of law, or for estate planning or charitable purposes, (ii) to stockholders, corporations, partnerships or other business entities that are direct or indirect affiliates (within the meaning set forth in Rule 405 under the Securities Act), current or former partners (general or limited), members or managers of the Stockholder, as applicable, or to the estates of any such stockholders, affiliates, general or limited partners, members or managers, or to another corporation, partnership, limited liability company or other investment or business entity that controls, is controlled by or is under common control with the Stockholder or (iii) if the Stockholder is a trust, to any beneficiary of the Stockholder or the estate of any such beneficiary; provided that in each such 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 Stockholder or the transferee provides the Company with a copy of such agreement promptly upon consummation of any such Transfer, (y) with respect to the Stockholder’s Options which expire on or prior to the termination of this Agreement, the Stockholder may make Transfers of the Subject Shares (i) to Caladrius as payment for the exercise price of the Stockholder’s Options and (ii) as payment for taxes applicable to the exercise of the Stockholder’s Options and (z) the Stockholder may take all actions reasonably necessary to consummate the transactions contemplated by the Merger Agreement. 1.3.

Caladrius is an intended third-party beneficiary of this Section 1.3. 1.4. Irrevocable Proxy. The Stockholder hereby revokes (or agrees to cause to be revoked) any proxies that the Stockholder has heretofore granted with respect to the Subject Shares. The Stockholder hereby irrevocably appoints the Company, and any individual designated in writing by it, as attorney-in-fact and proxy for and on behalf of the Stockholder, for and in the name, place and stead of the Stockholder, to: (a) attend any and all meetings of the Caladrius Stockholders, (b) vote, express consent or dissent or issue instructions to the record holder to vote the Stockholder’s Subject Shares in accordance with the provisions of Section 1.1 at any and all meetings of the Caladrius Stockholders or in connection with any action sought to be taken by written consent of the Caladrius Stockholders 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 the Caladrius Stockholders or in connection with any action sought to be taken by written consent without a meeting..

Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible. 4.9. Specific Performance. The parties hereto agree that the Company would be irreparably damaged if for any reason the Stockholder fails to perform any of its obligations under this Agreement and that the Company may not have an adequate remedy at law for money damages in such event. Accordingly, the Company shall be entitled to specific performance and injunctive and other equitable relief to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof in any Delaware Court, in addition to any other remedy to which they are entitled at law or in equity, in each case without posting bond or other security, and without the necessity of proving actual damages. 4.10.
