This VOTING AGREEMENT (this "Agreement"), dated as of August 11, 2016, is by and among Blackford Dental Management Holdings, LLC, a Delaware limited liability company (and together with its affiliates, "Blackford") and the persons executing this agreement at "Stockholders" on the signature page hereto (each, a "Stockholder" and collectively, the "Stockholders").

WHEREAS, Blackford has expressed an interest in acquiring Birner Dental Management Services, Inc., a Colorado corporation (the "Company") through a merger or other transaction with a per share price of between $23 and $25.30 (the "Transaction");

WHEREAS, as of the date hereof, each Stockholder beneficially owns the number of Common Shares of the Company set forth opposite the name of such Stockholder on Schedule A hereto (together with any Common Shares and any other voting securities of the Company that such Stockholders acquire beneficial ownership of after the date hereof, the "Owned Shares");

WHEREAS, as an inducement to entering into discussions with the Company regarding a Transaction, the Stockholders agree to enter into this Agreement; and

WHEREAS, the Stockholders and Blackford desire to set forth their agreement with respect to the voting of the Owned Shares upon the terms and subject to the conditions set forth herein.

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

1. Voting; Etc.

(a) Agreement to Vote. Each Stockholder hereby agrees that, from and after the date hereof and until this Agreement shall have been terminated in accordance with Section 6:

(i) At any meeting of the stockholders of the Company called for purposes that include approval of the Transaction, however called, or at any adjournment or postponement thereof, or in connection with any written consent of the stockholders of the Company or in any other circumstances in which the Stockholders are entitled to vote, consent or give any other approval with respect to the Transaction, each Stockholder, as applicable, shall (x) appear at such meeting or otherwise cause its Owned Shares to be counted as present thereat for purposes of calculating a quorum, and respond to each request by the Company for written consent, if any, (y) vote or cause to be voted (including by written consent, if applicable) the number of Owned Shares, to the extent such Owned Shares are entitled to be voted (A) in favor of the Transaction and the approval of the terms thereof and each of the other actions contemplated by the Transaction and this Agreement and (B) in favor of the approval of any other matter that is required by applicable Law or a Governmental Entity to be approved by the stockholders of the Company to consummate the Transaction, (c) shall vote the Owned Shares against approval of any proposal made in opposition to, or in competition with, consummation of the Transaction with any third party, as long as such proposal, whether to acquire the Company through any type of transaction, including any merger, consolidation, business combination, sale of assets, or reorganization of the Company, is at a per share price lower or equal to the per share price than the then existing per share price agreed by Blackford as part of the Transaction and (d) subject to the conditions set forth in (c) immediately above, shall vote the Owned Shares against (i) any merger, consolidation, business combination, sale of assets, or reorganization of the Company, or (ii) any other action, any of which is intended, or could reasonably be expected to, impede, interfere with, delay, postpone, discourage or adversely affect the Transaction. Notwithstanding anything in this Agreement to the contrary, in no event shall any Stockholder be required to take any of the actions set forth in this Paragraph 1(a)(i) in the event that at any time during pendency of the Transaction there shall be an alternative proposal to the Transaction (including any merger, consolidation, business combination, sale of assets, a reorganization of the Company as well as any reorganization, recapitalization, dissolution, liquidation or winding up of the Company or any sale, lease, or transfer of any significant part of the assets of the Company) that is a per share price of at least greater than the then existing per share price in the Transaction unless such third-party offer is matched in all substantive respects by Blackford within five business days after Stockholder provides notice of such offer to Blackford.

(b) Transfer Restrictions. Each Stockholder agrees not to directly or indirectly (i) sell, transfer, grant, pledge, encumber, assign or otherwise dispose of or hypothecate (including by gift or by contribution or distribution to any trust or similar instrument (collectively, "Transfer")), or enter into any contract, option or other arrangement or understanding (including any profit sharing arrangement) with respect to the Transfer of, any of the Owned Shares other than pursuant to the terms hereof, (ii) enter into any voting arrangement or understanding with respect to the Owned Shares (other than this Agreement), whether by proxy, voting agreement or otherwise, or (iii) take any action that could make any of its representations or warranties contained herein untrue or incorrect in any material respect or would have the effect of preventing or disabling such Stockholder from performing any of its obligations hereunder. Any action attempted to be taken in violation of the preceding sentence will be null and void. For the avoidance of doubt, (i) nothing herein shall be construed to prohibit the exercise by Stockholder of any options to acquire any Common Shares and (ii) any shares of Common Shares obtained by the Stockholder upon such exercise shall be included in the Owned Shares.

(c) Recommendation Change.
