EXPLANATORY NOTE



This Amendment No. 1 on Form 10-K/A (this
“Form 10-K/A”) amends the Annual Report on Form 10-K for the year ended December 31, 2016 filed by Birner Dental Management
Services, Inc. (the “Company”) with the Securities and Exchange Commission (the “SEC”) on March 31, 2017
(the “2016 Form 10-K”). This Form 10-K/A is being filed to include certain information that was previously omitted
from Part III of the 2016 Form 10-K because the Company no longer intends to file a definitive proxy statement for an annual meeting
of shareholders within 120 days after the end of its fiscal year ended December 31, 2016. In particular, this Form 10-K/A amends
the cover page and amends and restates Items 10 through 14 of Part III. Pursuant to Rule 12b-15 under the Securities Exchange
Act of 1934, as amended (the “Exchange Act”), this Form 10-K/A also contains new certifications by the principal executive
officer and the principal financial officer as required by Section 302 of the Sarbanes-Oxley Act of 2002. Accordingly, Item 15
of Part IV is amended and restated to include the currently dated certifications as exhibits. Because no financial statements
have been included in this Form 10-K/A and this Form 10-K/A does not contain or amend any disclosure with respect to Items 307
and 308 of Regulation S-K, paragraphs 3, 4, and 5 of the certifications have been omitted. The cover page of the 2016 Form 10-K
is also amended to delete the reference to the incorporation by reference of the Company’s definitive proxy statement.



Except as otherwise expressly noted above,
this Form 10-K/A does not amend any other information set forth in the 2016 Form 10-K. This Form 10-K/A continues to speak as
of the date of the 2016 Form 10-K and, except where expressly noted, the Company has not updated disclosures contained therein
to reflect any events that occurred at a date subsequent to the date of the 2016 Form 10-K. Accordingly, this Form 10-K/A should
be read in conjunction with the 2016 Form 10-K and the Company’s other filings with the SEC.



Capitalized terms not otherwise defined
in this Form 10-K/A shall have the meanings ascribed to them in the 2016 Form 10-K.

the SEC initial reports of ownership and reports regarding changes in their beneficial ownership of our shares. To our knowledge,

2016 were filed on a timely basis.

Corporate
Governance matters



Code of Conduct



All of our employees, including our Chief
Executive Officer, Chief Financial Officer, and the persons performing similar functions, are required to abide by our code of
conduct and business conduct policies to ensure that our business is conducted in a consistently legal and ethical manner. We
intend to disclose any changes in or waivers from our code of conduct by filing a current report on Form 8-K with the SEC.
A copy of the Company’s Code of Conduct is available on our website at www.perfectteeth.com/legal.



Nominations Process



We do not have a standing nominating committee
or a nominating committee charter. Nominations for director are made by our independent directors. The Board of Directors believes
that, considering the size of the Company and our Board of Directors, nominating decisions can be made effectively by our independent
directors and there is no need for the added formality of a nominating committee.



On July 15, 2016, our Board of Directors
adopted and approved the Second Amended and Restated Bylaws of the Company (the “Amended Bylaws”). The Amended Bylaws
include advance notice requirements and procedures for the submission by shareholders of nominations for our Board of Directors
and of other proposals to be presented at shareholder meetings.



Under Article II, Section 3 of the Amended
Bylaws, in order for a shareholder to nominate a person for election as a director without inclusion in our proxy statement, such
shareholder must give timely notice in writing delivered to our Secretary at the Company’s principal executive offices.
To be timely, notice must be delivered to the Secretary not later than the close of business on the 90th day, nor earlier than
the close of business on the 120th day, prior to the first anniversary of the preceding year’s annual shareholders’
meeting. If the date of the annual shareholders’ meeting is more than 30 days before or more than 60 days after such anniversary
date, to be timely, notice by the shareholder must be delivered not earlier than the close of business on the 120th day prior
to the date of such annual shareholders’ meeting and not later than the close of business on the later of the 90th day prior
to the date of such annual shareholders’ meeting or the 10th day following the day on which we first publicly announce the
date of such annual shareholders’ meeting.



The shareholder’s notice must include
certain information required by the Amended Bylaws about the director nominee, the shareholder of record and the underlying beneficial
owner, if any, including such information as the director nominee’s name, age, address, occupation and shares; the name,
address and shares of the shareholder and any beneficial owner; information about derivatives, hedges and short positions; understandings
or agreements regarding the economic and voting interests of the director nominee, the shareholder and related persons with respect
to our stock, if any; and such other information as would be required to be disclosed in a proxy statement soliciting proxies
for the election of the proposed director nominee. In addition, the notice must contain certain representations made by the shareholder
or beneficial owner proposing to nominate such director nominee. We may require any proposed nominee to furnish such other information
as may reasonably be required to determine the eligibility of such proposed nominee to serve as a director. A shareholder’s
notice must be updated, if necessary, so that the information submitted is true and correct as of the record date for determining
shareholders entitled to receive notice of the meeting and as of the date that is 10 business days prior to the meeting date.





6







The Board of Directors does not have an
express policy with regard to the consideration of any director candidates recommended by our shareholders because the Board believes
that it can adequately evaluate any such nominees on a case-by-case basis. The Board of Directors will consider director candidates
proposed on a timely basis in accordance with the Amended Bylaws and will evaluate shareholder-recommended candidates under the
same criteria as internally generated candidates. Shareholders must include sufficient information about candidates nominated
for director as set forth in the Amended Bylaws to enable our independent directors to consider the candidate’s qualifications
and suitability for service on the Board of Directors. Although the Board of Directors does not currently have a diversity policy
regarding selection of director nominees or other formal minimum criteria for nominees, substantial relevant business and industry
experience would generally be considered important qualifying criteria, as would the ability to attend and prepare for Board,
committee and shareholder meetings. In considering nominees, the Board would consider diversity among other factors relevant to
its decision. Any candidate must state in advance his or her willingness and interest in serving on the Board of Directors and
its committees. 1



Audit Committee



The Audit Committee is comprised solely
of independent directors, as defined by applicable Nasdaq and SEC rules and regulations. Though our Company is no longer listed
on Nasdaq, our Board of Directors used the Nasdaq listing standards in making its independence determinations. The current members
of the Audit Committee are Brooks G. O’Neil, Paul E. Valuck, D.D.S. and Thomas D. Wolf (Chairman). The Board of Directors
has reviewed Nasdaq Rule 5605(c) and has determined that Messrs. O’Neil, Valuck and Wolf are independent directors as defined
in that rule. The Board of Directors has determined that Messrs. O’Neil and Wolf have accounting and related financial management
expertise based on their years of relevant professional work experience and are qualified as audit committee financial experts
within the meaning of SEC regulations.


















1A number of sections have been deleted from Item 10 because, although
they are required in proxy statements under Schedule 14A, they are not required to be included in Item 10 of Form 10-K.

Base Salary and Bonus



The Compensation Committee reviews the
base salaries of the Company's executive officers on an annual basis. The Compensation Committee also determines bonuses. Base
salaries and bonuses are determined based upon a subjective assessment of the nature and responsibilities of the position involved,
the performance of the particular executive officer and of the Company, the executive officer's experience and tenure with the
Company and base salaries paid to persons in similar positions with companies comparable to the Company. Messrs. Birner and Genty
did not receive a base salary increase, a bonus or any equity awards during 2015 or 2016. Messrs. Birner and Genty agreed to reduce
their base salaries by 20% effective February 1, 2017.



Grant of Plan-Based Awards



In November 2014, the Compensation Committee
granted options to purchase 30,000 shares of common stock to each of Mr. Birner and Mr. Genty. For each of Mr. Birner and Mr.
Genty, 10,000 options vested on November 12, 2015, 10,000 options vested on November 12, 2016 and 10,000 options will vest on
November 12, 2017. The option awards were granted under our 2005 Equity Incentive Plan, as amended (the “2005 Plan”),
which terminated on March 17, 2015.

Payments upon Change in Control



As of April 27, 2017, there were 394,666
options issued and outstanding under our 2005 Plan, which terminated in March 2015, and there were 106,000 options issued and
outstanding under our 2015 Equity Incentive Plan (the “2015 Plan”).



Upon a change of control of our Company,
as defined in the 2005 Plan, all outstanding options issued under our 2005 Plan will automatically vest.



Under the 2015 Plan, a “change in
control” is generally defined as a merger or consolidation involving us, a sale of all or substantially all of our assets,
the acquisition by a person or group of more than 30% of the voting power of our stock, or certain changes in the composition
of our board of directors. Under the 2015 Plan, if a change in control of our company occurs as a result of a merger or consolidation
involving us and any outstanding award is not continued, assumed or replaced by the company or the surviving or successor entity
in connection with the change in control, then (i) each of the participant's outstanding options and SARs will become exercisable
in full, and (ii) each of the participant's unvested full value awards will fully vest unless and to the extent the committee
that administers the 2015 Plan elects to terminate such award in exchange for a payment in an amount equal to the intrinsic value
of the award (or, if there is no intrinsic value, the award may be terminated without payment). Upon the occurrence of other events
involving a change in control (as defined in the 2015 Plan), all exercise dates of any outstanding award will accelerate and all
outstanding awards will vest. The committee may provide for different change in control consequences in an individual award agreement.

we were or will be a party in which the amount involved exceeded or will exceed $120,000 and in which any related person had or
will have a direct or indirect material interest. We do not have a formal written policy regarding the review, approval or ratification
of related party transactions. Under the Audit Committee charter, the Audit Committee is responsible for the review and approval
of all related party transactions required to be disclosed to the public under the SEC rules. All of our employees, officers and
directors are required to comply with our Code of Conduct. The Code of Conduct addresses, among other things, actions that are
required when potential conflicts of interest arise, including those from related party transactions. Specifically, if an employee,
officer or director believes a conflict of interest exists or may arise, he or she is required to disclose immediately the nature
and extent of the conflict, or potential conflict, to his or her supervisor, who, along with appropriate officials of the Company,
will evaluate the conflict and take the appropriate action, if any, to ensure that our interests are protected. Any transaction
between us and another party on terms that are reasonably believed to be at least as favorable as the terms that we otherwise
could have obtained from an unrelated third party shall not create a conflict of interest or cause a violation of the Code of
Conduct, provided that with respect to the directors and any member of senior management, the Audit Committee was given prior
notice of such transaction and approved it. The rules in the Code of Conduct regarding conflicts of interest not only apply to
all employees, officers and directors, but also to immediate family members and certain business associates of our employees,
officers and directors.
