VOTING AGREEMENT

This VOTING AGREEMENT (this “Agreement”) is entered into as of July __, 2019, among Gemphire Therapeutics Inc., a Delaware corporation (“Parent”), NeuroBo Pharmaceuticals, Inc., a Delaware corporation (the “Company”), and the undersigned stockholder (the “Stockholder”) of Parent.

WHEREAS, as of the date hereof, the Stockholder is the sole record and beneficial owner of and has the sole power to vote (or to direct the voting of) the number of shares of common stock, par value $0.001 per share (the “Common Stock”), of Parent, set forth opposite the Stockholder’s name on Schedule I hereto (such Common Stock together with any other shares of Parent (“Shares”) the voting power of which is acquired by such Stockholder during Voting Period (defined below), are collectively referred to herein as the “Subject Shares”);

WHEREAS, the Company, Parent, and GR Merger Sub Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Sub”), are concurrently entering into an Agreement and Plan of Merger and Reorganization, dated on or about the date hereof (as amended from time to time, the “Merger Agreement”), pursuant to which Merger Sub shall be merged with and into the Company, with the Company continuing as the surviving corporation thereafter (the “Merger”);

WHEREAS, the adoption of the Merger Agreement and the transactions contemplated thereby requires the affirmative vote of the holders of a majority of the shares of Common Stock outstanding on the applicable record date and entitled to vote thereon; and

WHEREAS, as an inducement to the Company’s and Parent’s willingness to enter into the Merger Agreement and consummate the transactions contemplated thereby, transactions from which the Stockholder believes it will derive substantial benefits through its ownership interest in the combined company, the Stockholder is entering into this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth herein, the parties agree as follows:

ARTICLE I

DEFINITIONS

SECTION 1.1 Capitalized Terms. For purposes of this Agreement, capitalized terms used and not defined herein shall have the respective meanings ascribed to them in the Merger Agreement.

VOTING AGREEMENT AND IRREVOCABLE PROXY

SECTION 2.1 Agreement to Vote. The Stockholder hereby agrees that, during the Voting Period, and at any duly called meeting of the stockholders of Parent (or any adjournment or postponement thereof), or in any other circumstances (including action by written consent of stockholders in lieu of a meeting) upon which a vote, adoption or other approval or consent with respect to the adoption of the Merger Agreement or the approval of the Merger and any of the transactions contemplated thereby is sought, the Stockholder shall, if a meeting is held, appear at the meeting, in person or by proxy, and shall provide a written consent or vote (or cause to be voted), in person or by proxy, all its Subject Shares, in each case (a) in favor of (i) any proposal to adopt and approve or reapprove the Merger Agreement and the transactions contemplated thereby, including without limitation (A) the amendment of Parent’s certificate of incorporation to effect the Reverse Split, (B) the amendment to Parent’s certificate of incorporation to change the name of Parent to “NeuroBo Pharmaceuticals, Inc.”, (C) the issuance of shares of Parent Common Stock to the Company’s stockholders in connection with the Contemplated Transactions and the change of control of Parent resulting from the Merger pursuant to the Nasdaq rules, (D) the adoption and approval of the 2019 Plan, and (E) any other proposal in connection with, or related to, the consummation of the Merger for which the Parent Board has recommended that Parent’s stockholders vote in favor and (ii) waiving any notice that may have

been or may be required relating to the Merger or any of the other transactions contemplated by the Merger Agreement and (b) against (i) any Acquisition Proposal and any action in furtherance of any such Acquisition Proposal, and (ii) any action, proposal, transaction or agreement that, to the knowledge of the Stockholder, would reasonably be expected to result in a material breach of any covenant, representation or warranty or any other obligation or agreement of the Stockholder under this Agreement. As used herein, the term “Expiration Time” shall mean the earliest occurrence of (x) the Effective Time and (y) the date and time of the valid termination of the Merger Agreement in accordance with its terms, and the term “Voting Period” shall mean such period of time between the date hereof and the Expiration Time.

SECTION 2.2 Grant of Irrevocable Proxy. The Stockholder hereby appoints Parent and any designee of Parent, and each of them individually, as the Stockholder’s proxy, with full power of substitution and resubstitution, to vote, including by executing written consents, during the Voting Period with respect to any and all of the Subject Shares on the matters and in the manner specified in Section 2.1. The Stockholder shall take all further action or execute such other instruments as may be necessary to effectuate the intent of any such proxy. The Stockholder affirms that the irrevocable proxy given by it hereby with respect to the Merger Agreement and the transactions contemplated thereby is given to Parent by the Stockholder to secure the performance of the obligations of the Stockholder under this Agreement. It is agreed that Parent (and its officers on behalf of Parent) will use the irrevocable proxy that is granted by the Stockholder hereby only in accordance with applicable Laws and that, to the extent Parent (and its officers on behalf of Parent) uses such irrevocable proxy, it will only vote (or sign written consents in respect of) the Subject Shares subject to such irrevocable proxy with respect to the matters specified in, and in accordance with the provisions of, Section 2.1.

SECTION 2.3 Nature of Irrevocable Proxy. The proxy granted pursuant to Section 2.2 to Parent by the Stockholder shall be irrevocable during the term of this Agreement, shall be deemed to be coupled with an interest sufficient in law to support an irrevocable proxy and shall revoke any and all prior proxies or powers of attorney granted by the Stockholder 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 Stockholder with respect thereto. The proxy that may be granted hereunder shall terminate upon the termination of this Agreement, but shall survive the death or incapacity of the Stockholder and any obligation of the Stockholder under this Agreement shall be binding upon the heirs, personal representatives and successors of the Stockholder.

Without limiting the foregoing, it is understood that any violation of the foregoing restrictions by any Representatives of the Stockholder shall be deemed to be a breach of this Section 3.3 by the Stockholder. The Stockholder shall, and shall use reasonable best efforts to cause its Representatives to, immediately cease any and all existing discussions or negotiations with any Persons conducted heretofore with respect to any Acquisition Proposal.

SECTION 3.4 Communications. During the Voting Period, the Stockholder shall not, and shall use its reasonable best efforts to cause its Representatives, if any, not to, directly or indirectly, make any press release, public announcement or other public communication that criticizes or disparages this Agreement or the Merger Agreement or any of the transactions contemplated hereby and thereby, without the prior written consent of Parent and the Company, provided that the foregoing shall not limit or affect any actions taken by the Stockholder (or any affiliated officer or director of Stockholder) that would be permitted to be taken by Stockholder pursuant to the Merger Agreement.

WAIVER, (b) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (c) EACH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (d) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 6.11.

SECTION 6.12 Counterparts.
