SPECIAL MEETING OF SHAREHOLDERS

TO BE HELD ON NOVEMBER 5, 2012

This Proxy Statement is being furnished to the shareholders of Graymark Healthcare, Inc. (“Graymark,” “Graymark Healthcare” or the “Company”) in connection with a special meeting of the shareholders of Graymark Healthcare, Inc. (the “Special Meeting”) to be held in the Conference Room located at One Leadership Square, North Tower, 211 North Robinson, Suite 255, Oklahoma City, Oklahoma 73102, at 9:30 a.m., central standard time, on November 5, 2012, and any adjournment or postponement of the Special Meeting. Proxies in the form included with this Proxy Statement are solicited by the Company’s Board of Directors. This Proxy Statement and the accompanying Notice of Special Meeting of Shareholders and proxy will be first sent or given on or about October 9, 2012. If you require directions to the location of the Special Meeting, please telephone (405) 601-5300.

The shareholders entitled to vote at the Special Meeting are the holders of record, at the close of business on October 4, 2012 (the “Record Date”). As of the Record Date, 15,195,634 shares of common stock were issued and outstanding. Each holder of a share of common stock outstanding on the Record Date will be entitled to one vote for each share held on each matter presented at the Special Meeting.

Voting

The persons named as attorneys-in-fact in the proxy, Stanton Nelson and Mark Kidd, were selected by the Board of Directors. If the accompanying proxy is properly executed and returned, the shares of common stock represented by the proxy will be voted at the Special Meeting. If you indicate on the proxy a choice with respect to any matter to be voted on, your shares will be voted in accordance with your choice. If no choice is indicated, your shares of common stock will be voted FOR an amendment to Graymark Healthcare’s Restated Certificate of Incorporation to effect a reverse stock split of its common stock at a ratio, to be determined by the Board of Directors, in the range of 1-for-2 to 1-for-10 (the “Reverse Stock Split”). In addition, your shares will also be considered and voted upon such other business that may properly come before the Special Meeting or any adjournment or postponement thereof. Our Board of Directors knows of no business that will be presented for consideration at the Special Meeting other than matters described in this Proxy Statement.

Except where otherwise provided by statute or by our organizational documents, the representation, in person or by proxy, of at least one third of the outstanding shares of common stock entitled to vote at the Special Meeting is necessary to constitute a quorum for the transaction of business. Shares represented by proxies which contain one or more abstentions or broker “non-votes,” are counted as present or represented for purposes of determining the presence or absence of a quorum for the Special Meeting. A “non-vote” occurs when a broker or other nominee holding shares for a beneficial owner votes on a proposal, but does not vote on another proposal because the broker does not have discretionary voting power and has not received instructions from the beneficial owner. Absent instructions from the beneficial owner of shares held in a brokerage account or by a nominee, a broker or nominee is not entitled to vote shares held for beneficial holders on any proposal being presented at the Special Meeting. Therefore, to ensure your vote is counted, please instruct your bank or broker to vote your shares.

Neither the corporate laws of Oklahoma, the state in which we are incorporated, nor our Restated Certificate of Incorporation or Amended and Restated Bylaws have any provisions regarding the treatment of abstentions and broker non-votes. Accordingly, (i) abstentions and broker non-votes are counted for purposes of determining the presence of a quorum at the Special Meeting, (ii) abstentions are treated as votes not cast but as shares represented at the Special Meeting for purposes of determining results on actions requiring a majority vote, and (iii) broker non-votes are treated as votes not cast and are not considered shares represented at the Special Meeting for purposes of determining results on actions taken at the Special Meeting.

Revocation of Proxies

Once given, you may revoke the proxy by:

Vote Required

The affirmative vote of a majority of the issued and outstanding shares of our common stock is required to approve the Amendment to effect the Reverse Stock Split. The Board knows of no other matters to be presented at the Special Meeting. If any other matter should be presented at the Special Meeting upon which a vote may properly be taken, the affirmative vote of the majority of shares voted at the Special Meeting is required for approval, unless otherwise required by law or our Restated Certificate of Incorporation or Amended and Restated Bylaws.

Methods of Voting

You may vote by mail, by telephone, over the internet or in person at the Special Meeting.

Voting by Mail. By signing and returning the proxy card in the enclosed prepaid and addressed envelope, you are authorizing the individuals named on the proxy card to vote your shares at the Special Meeting in the manner you indicate.

PROPOSAL ONE

APPROVAL OF AMENDMENT TO THE COMPANY’S RESTATED

CERTIFICATE OF INCORPORATION TO EFFECT A REVERSE STOCK SPLIT

The Company’s Board of Directors is seeking shareholder approval to give the Board authorization to amend the Company’s Restated Certificate of Incorporation to effect a reverse stock split of our issued and outstanding common stock (the “Reverse Stock Split”) in one of ten ratios, namely 1-for-2, 1-for-3, 1-for-4, 1-for-5, 1-for-6, 1-for-7, 1-for-8, 1-for-9, or 1-for-10 shares, with the final ratio to be determined by the Board following shareholder approval. If approved and the Board determines to implement the Reverse Stock Split, the Company would file an amendment to our Restated Certificate of Incorporation with the Secretary of State of the State of Oklahoma (the “Amendment”) to effect the Reverse Stock Split without further approval of our shareholders. For the reasons described below, the Board has determined that the Reverse Stock Split and Amendment are advisable and in the best interests of the Company and its shareholders. The full text of the proposed Amendment is attached as Annex A.

The Board is seeking approval of its shareholders to effect the Reverse Stock Split in order to give it the flexibility to take action to increase the price of our common stock sufficiently above the $1.00 minimum bid price required for continued listing of our common stock on The NASDAQ Capital Market and to sustain long term compliance with the listing requirements of The NASDAQ Stock Market (“NASDAQ”), as discussed below. The Board, in its sole discretion, may elect to abandon the Reverse Stock Split in its entirety even if our shareholders approve the Reverse Stock Split.

The principal effect of the Reverse Stock Split would be to decrease the number of outstanding shares of our common stock and correspondingly increase the per share price of our common stock. Except for de minimis adjustments that may result from the treatment of fractional shares as described below, the Reverse Stock Split will not have any dilutive effect on our shareholders since each shareholder would hold the same percentage of our common stock outstanding immediately following the Reverse Stock Split as such shareholder held immediately prior to the Reverse Stock Split. The relative voting and other rights that accompany the shares of common stock would not be affected by the Reverse Stock Split.

Although the Reverse Stock Split will not have any dilutive effect on our shareholders, the proportion of shares owned by our shareholders relative to the number of shares authorized for issuance will decrease because the proposed Amendment maintains the current authorized number of shares of common stock at 500,000,000. The remaining authorized shares may be used for various purposes, including, without limitation, raising capital, providing equity incentives to employees, officers or directors, effecting stock dividends, establishing strategic relationships with other companies and expanding the Company’s business or product lines through the acquisition of other businesses or products. In order to support the Company’s projected need for additional equity capital and to provide flexibility to raise the capital necessary to finance ongoing operations, the Board of Directors believes the number of shares of Common Stock the Company is authorized to issue should be maintained at 500,000,000.

4

The Company expects it will need to raise additional capital in order to improve the Company’s financial condition. This Proxy Statement is not an offer to sell or the solicitation of an offer to buy the Company’s securities issuable in any capital raising transaction. Offers and sales of securities issuable in any capital raising transaction will only be made by means of a prospectus meeting the requirements of the Securities Act of 1933, as amended, and applicable state securities laws, on the terms and subject to the conditions set forth in such prospectus or pursuant to a private placement transaction pursuant to an exemption from the registration requirements of the Securities Act.

The Reverse Stock Split is not part of a broader plan to take the Company private. If the Reverse Split is approved by the shareholders but is not subsequently implemented by the Board by December 31, 2012, then the proposed Amendment shall be deemed abandoned without any further effect.

Reasons for the Reverse Stock Split

The primary reason for proposing the Reverse Stock Split is to increase the per share market price of our common stock. Our common stock is currently listed on The NASDAQ Capital Market under the symbol “GRMH,” which we believe helps support and maintain stock liquidity and company recognition for our stockholders. As previously disclosed, on December 21, 2011, the Company received a letter from NASDAQ providing notice that, for the 30 consecutive trading days preceding such notice, the closing bid price per share of our common stock had been below the $1.00 minimum per share requirement for continued listing under NASDAQ Marketplace Rule 5550(a)(2). In accordance with NASDAQ Marketplace Rule 5810(c)(3)(A), the Corporation was provided 180 calendar days, or until June 18, 2012, to regain compliance by maintaining a closing bid price per share of $1.00 or higher for a minimum of 10 consecutive business days. Because the Company did not regain compliance with the minimum bid price requirement by that date, on June 19, 2012, the Company received a delisting determination letter from NASDAQ. The Company filed an appeal regarding the delisting determination letter and on July 26, 2012, the Company presented its proposed plan of compliance to a Nasdaq Hearings Panel (the “Panel”). At the Panel hearing, the Company made a commitment to effect a reverse stock split, if necessary, in order to regain compliance.

Following the hearing, NASDAQ informed the Company that it determined to allow the continued listing of the Company’s common stock provided it met certain conditions as outlined in the Company’s plan of compliance by specified dates, including closing the proposed acquisition of Foundation Surgery Affiliates, LLC and Foundation Surgical Hospital Affiliates, LLC, reporting shareholders’ equity in excess of $2.5 million, and evidencing a closing bid price of no less than $1.00 for a minimum of ten consecutive trading days on or before November 29, 2012.

Any delisting would adversely affect the market price of and liquidity of the trading market for our common stock, our ability to obtain financing for the continuation of our operations and could result in the loss of confidence by investors, suppliers and employees. In order to maintain our listing on NASDAQ, we must satisfy minimum financial and other requirements, including maintaining the minimum closing bid price requirement of at least $1.00 per share. As of October 4, 2012, the closing bid price of our common stock was $0.40.

5

By potentially increasing the market price of our common stock through the Reverse Stock Split, we would meet the conditions of the Panel for continued listing on NASDAQ and reduce the risk that our common stock will be delisted in the future. We believe that the liquidity and marketability of our common stock will be adversely affected if it is not quoted on a national securities exchange as investors can find it more difficult to dispose of, or to obtain accurate quotations as to the market value of, our common stock. The Board of Directors believes that current and prospective investors will view an investment in our common stock more favorably if our common stock remains listed on The NASDAQ Capital Market.

The Board of Directors also believes that the Reverse Stock Split and any resulting increase in the per share price of our common stock should enhance the acceptability and marketability of our common stock to the financial community and investing public. Many institutional investors have policies prohibiting them from holding lower-priced stocks in their portfolios, which reduces the number of potential buyers of our common stock. Additionally, analysts at many brokerage firms are reluctant to recommend lower-priced stocks to their clients or monitor the activity of lower-priced stocks. Brokerage houses frequently have internal practices and policies that discourage individual brokers from dealing in lower-priced stocks. Further, because brokers’ commissions on lower-priced stock generally represent a higher percentage of the stock price than commissions on higher priced stock, investors in lower-priced stocks pay transaction costs which are a higher percentage of their total share value, which may limit the willingness of individual investors and institutions to purchase our common stock.

If shareholders approve the Reverse Stock Split, in addition to the considerations noted above, the Board will consider other factors in evaluating whether or not to authorize the Reverse Stock Split and determining the appropriate split ratio various factors, including:

As noted above, even if stockholders approve the proposed Reverse Stock Split, the Company reserves the right not to effect the Reverse Stock Split if the Board does not deem it to be advisable and in the best interests of the Company and its shareholders.

6

We cannot assure you that the Reverse Stock Split will have any of the desired effects described above. More specifically, we cannot assure you that after the Reverse Stock Split the market price of our common stock will increase proportionately to reflect the ratio for the Reverse Stock Split, that the market price of our common stock will not decrease to its pre-split level, that our market capitalization will be equal to the market capitalization before the Reverse Stock Split, or that we will be able to maintain our listing on The NASDAQ Capital Market. Even if the Reverse Stock Split is approved and the Board determines to implement the Reverse Stock Split, our common stock may still be delisted if our common stock does not trade above the $1.00 minimum bid price requirement for at least ten consecutive trading days or if we do not meet the other conditions imposed by the Panel for continued listing of our common stock. As previously disclosed, we received a notice from NASDAQ that on August 16, 2012, that we are not in compliance with the continued listing standards for primary equity securities on The NASDAQ Capital Market because our stockholders’ equity was less than $2.5 million at June 30, 2012, and we did not meet the alternative standards of market value of listed securities or net income from continuing operations. While we believe our proposed plan of compliance will satisfactorily address the bid price and stockholders’ equity deficiencies once executed, we cannot guarantee that NASDAQ will ultimately determine that the Company has fully complied with the continued listing requirements.

If the shareholders do not approve the Reverse Stock Split, it is expected that NASDAQ would proceed with a delisting of our common stock, and that our common stock would instead be quoted and traded on the OTCQB market under the symbol “GRMH.”

Potential Disadvantages of a Reverse Stock Split

As noted above, the principal purpose of the Reverse Stock Split would be to help increase the per share market price of our common stock by up to factor of ten. We cannot assure you, however, that the Reverse Stock Split will accomplish this objective for any meaningful period of time. While we expect that the reduction in the number of outstanding shares of common stock will increase the market price of our common stock, we cannot assure you that the Reverse Stock Split will increase the market price of our common stock by a multiple equal to the number of pre-split shares, or result in any permanent increase in the market price of our stock, which is dependent upon many factors, including our business and financial performance, general market conditions and prospects for future success. If the per share market price does not increase proportionately as a result of the Reverse Stock Split, then the value of the Company as measured by our stock capitalization will be reduced, perhaps significantly.

The number of shares held by each individual shareholder would be reduced if the Reverse Stock Split is implemented. This will increase the number of shareholders who hold less than a “round lot,” or 100 shares. Typically, the transaction costs to shareholders selling “odd lots” are higher on a per share basis. Consequently, the Reverse Stock Split could increase the transaction costs to existing shareholders in the event they wish to sell all or a portion of their position.

7

Although the Board of Directors believes that the decrease in the number of shares of our common stock outstanding as a consequence of the Reverse Stock Split and the anticipated increase in the market price of our common stock could encourage interest in our common stock and possibly promote greater liquidity for our shareholders, such liquidity could also be adversely affected by the reduced number of shares outstanding after the Reverse Stock Split. In addition, even if the Reverse Stock Split is implemented and we meet the minimum bid price requirement, our common stock may still be delisted if we are unable to satisfy the other requirements for continued listing or the conditions imposed by the Panel for continued listing of our common stock.

The Board of Directors has considered the potential harm to the Company of a delisting from The NASDAQ Capital Market and believes it is in the best interests of the Company and its shareholders to effect the Reverse Stock Split to satisfy the Panel’s condition for continued listing and to potentially sustain long term compliance with NASDAQ listing requirements, including the $1.00 minimum bid price requirement.

Authorized Shares

If and when the Board of Directors elects to effect the Reverse Stock Split, the Amendment will concurrently therewith maintain the authorized number of shares of the Company’s common stock at 500,000,000. Accordingly, there will be no reduction in the number of authorized shares of our common stock in proportion to the reverse stock split ratio. As a result, the proportion of shares owned by our shareholders relative to the number of shares authorized for issuance will decrease and additional authorized shares of common stock will be available for issuance at such times and for such purposes as the Board of Directors may deem advisable without further action by our shareholders, except as required by applicable laws and regulations. Because our common stock is traded on The NASDAQ Capital Market, shareholder approval must be obtained, under applicable NASDAQ rules, prior to the issuance of shares for certain purposes, including the issuance of shares of the Company’s common stock equal to or greater than 20% of the Company’s then outstanding shares of common stock in connection with a private financing or an acquisition or merger, unless an exemption is available from such approval. Such an exemption would be available if our Audit Committee authorized the filing of an application with NASDAQ to waive the shareholder vote requirement if it believed the delay associated with securing such vote would seriously jeopardize the financial viability of the Company and NASDAQ granted the Company such an exemption.

Anti-Takeover and Dilutive Effects

The purpose of maintaining our authorized common stock at 500,000,000 after the Reverse Stock Split is to facilitate our ability to raise additional capital to support our operations, not to establish any barriers to a change of control or acquisition of the Company. Shares of common stock that are authorized but unissued provide our Board of Directors with flexibility to effect, among other transactions, public or private financings, acquisitions, stock dividends, stock splits and the granting of equity incentive awards. However, these authorized but unissued shares may also be used by the Board of Directors, consistent with and subject to its fiduciary duties, to deter future attempts to gain control of us or make such actions more expensive and less desirable. The Amendment would give our Board of Directors authority to issue additional shares from time to time without delay or further action by the shareholders except as may be required by applicable law or the NASDAQ rules. The Amendment is not being recommended in response to any specific effort of which the Company is aware to obtain control of the Company, nor does the Board of Directors have any present intent to use the authorized but unissued common stock to impede a takeover attempt. There are no plans or proposals to adopt other provisions or enter into any arrangements that have material anti-takeover effects.

8

In addition, the issuance of additional shares of common stock for any of the corporate purposes listed above could have a dilutive effect on earnings per share and the book or market value of our outstanding common stock, depending on the circumstances, and would likely dilute a shareholder’s percentage voting power in the Company. Holders of our common stock are not entitled to preemptive rights or other protections against dilution. Our Board of Directors intends to take these factors into account before authorizing any new issuance of shares.

Effects of the Reverse Stock Split

General

If approved by shareholders at the Special Meeting and if our Board of Directors concludes that it is in the best interests of the Company and its shareholders to effect the Reverse Stock Split, the Amendment will be filed with the Secretary of State of the State of Oklahoma. The actual timing of the filing of the Amendment with the Secretary of State of the State of Oklahoma to effect the Reverse Stock Split will be determined by the Board of Directors. Also, if for any reason the Board of Directors deems it advisable to do so, the Reverse Stock Split may be abandoned at any time prior to the filing of the Amendment, without further action by our shareholders. The text of the proposed Amendment is set forth in Annex A to this Proxy Statement. If and when effected by the Board, the Reverse Stock Split will be implemented by filing the Amendment with the Secretary of State of the State of Oklahoma, and the Amendment and Reverse Stock Split will be effective as of the date and time specified in the Amendment (the “Effective Time”).

Upon the filing of the Amendment, without further action on the part of the Company or the shareholders, the outstanding shares of common stock held by shareholders of record as of the Effective Time would be converted into a lesser number of shares of common stock based on a Reverse Stock Split ratio in the range of 1-for-2 to 1-for-10 shares, as determined by the Board of Directors. For example, if you presently hold 1,000 shares of our common stock, you would hold between 500 and 100 shares of our common stock following the Reverse Stock Split.

Effect on Outstanding Shares, Options and Certain Other Securities

If the Reverse Stock Split is implemented, the number of shares of our common stock owned by each shareholder will be reduced in the same proportion as the reduction in the total number of shares outstanding, such that the percentage of our common stock owned by each shareholder will remain unchanged except for any de minimis change resulting from rounding up to the nearest number of whole shares so that the Company is not obligated to issue cash in lieu of any fractional shares that such shareholder would have received as a result of the Reverse Stock Split. The number of shares of our common stock that may be purchased upon exercise of outstanding warrants, options or other securities convertible into, or exercisable or exchangeable for, shares of our common stock, and the exercise or conversion prices for these securities, will also be ratably adjusted in accordance with their terms as of the Effective Time.

9

The table below sets forth the number of shares of our common stock that would be (1) issued and outstanding; (2) authorized and reserved for issuance upon exercise of outstanding warrants, options and other securities convertible into our common stock; and (3) authorized and remaining available for future issuances, in each cash upon the implementation of the Reverse Stock Split at each ratio in the range from 1-for-2 to 1-for-10 based on our capitalization at October 4, 2012.

Effect on Registration and Stock Trading

Our common stock is currently registered under the Securities Act of 1933, as amended, and we are subject to the periodic reporting and other requirements of the Exchange Act. The proposed Reverse Stock Split will not affect the registration of our common stock. The Company presently does not intend to seek any change in its status as a reporting company for federal securities law purposes, either before or after the Reverse Stock Split.

If the proposed Reverse Stock Split is implemented, our common stock will continue to be reported on The NASDAQ Capital Market under the symbol “GRMH,” although the letter “D” will be added to the end of the trading symbol for a period of 20 trading days from the effective date of the Reverse Stock Split to indicate that the Reverse Stock Split has occurred.

Fractional Shares; Exchange of Shares

The Board of Directors does not currently intend to issue fractional shares in connection with the Reverse Stock Split. Therefore, we do not expect to issue certificates representing fractional shares. Shareholders of record who would otherwise hold a fractional share because the number of shares of common stock they hold before the Reverse Stock Split is not evenly divisible by the split ratio will be entitled to have their fractional share rounded up to the next whole number.

10

As of October 4, 2012, the Company had approximately 92 holders of record of the Company’s common stock (although the Company had significantly more beneficial holders). The Company does not expect the Reverse Stock Split and the rounding up of fractional shares to whole shares to result in a significant reduction in the number of record holders.

If the Reverse Stock Split is effected, shareholders who hold uncertificated shares (i.e., shares held in book-entry form and not represented by a physical certificate), either as direct or beneficial owners, will have their holdings electronically adjusted automatically by our transfer agent (and, for beneficial owners, by their brokers or banks that hold in “street name” for their benefit, as the case may be) to give effect to the Reverse Stock Split. Shareholders who hold uncertificated shares as direct owners will be sent a statement of holding from our transfer agent that indicates the number of post-reverse split shares of our common stock owned in book-entry form. Shareholders holding certificated shares (i.e., shares represented by one or more physical stock certificates) will receive a transmittal letter from our transfer agent promptly after the effective time of the Reverse Stock Split. The transmittal letter will be accompanied by instructions specifying how shareholders holding certificated shares can exchange certificates representing the pre-reverse split shares of our common stock for a statement of holding.

Shareholders will not have to pay any service charges in connection with the exchange of their certificates. YOU SHOULD NOT DESTROY ANY PHYSICAL STOCK CERTIFICATES AND YOU SHOULD NOT SUBMIT ANY CERTIFICATES UNTIL DIRECTED TO DO SO BY A TRANSMITTAL LETTER FROM OUR TRANSFER AGENT.

Accounting Consequences

As of the Effective Time, the stated capital attributable to common stock on our balance sheet will be reduced proportionately based on the reverse stock split ratio (including a retroactive adjustment of prior periods), and the additional paid-in capital account will be credited with the amount by which the stated capital is reduced. Reported per share net income or loss will be higher because there will be fewer shares of our common stock outstanding.

Federal Income Tax Consequences

The following summary describes certain material U.S. federal income tax consequences of the Reverse Stock Split to holders of our common stock.

Unless otherwise specifically indicated herein, this summary addresses the tax consequences only to a beneficial owner of our common stock that is a citizen or individual resident of the United States, a corporation organized in or under the laws of the United States or any state thereof or the District of Columbia or otherwise subject to U.S. federal income taxation on a net income basis in respect of our common stock (a “U.S. holder”). This summary does not address all of the tax consequences that may be relevant to any particular shareholder, including tax considerations that arise from rules of general application to all taxpayers or to certain classes of taxpayers or that are generally assumed to be known by investors. This summary also does not address the tax consequences to (a) persons that may be subject to special treatment under U.S. federal income tax law, such as banks, insurance companies, thrift institutions, regulated investment companies, real estate investment trusts, tax-exempt organizations, U.S. expatriates, persons subject to the alternative minimum tax, traders in securities that elect to mark to market and dealers in securities or currencies, (b) persons that hold our common stock as part of a position in a “straddle” or as part of a “hedging,” “conversion” or other integrated investment transaction for federal income tax purposes, or (c) persons that do not hold our common stock as “capital assets” (generally, property held for investment).

11

This summary is based on the provisions of the Internal Revenue Code of 1986, as amended (“IRC”), U.S. Treasury regulations, administrative rulings and judicial authority, all as in effect as of the date hereof. Subsequent developments in U.S. federal income tax law, including changes in law or differing interpretations, which may be applied retroactively, could have a material effect on the U.S. federal income tax consequences of the Reverse Stock Split.

If a partnership (or other entity classified as a partnership for U.S. federal income tax purposes) is the beneficial owner of our common stock, the U.S. federal income tax treatment of a partner in the partnership will generally depend on the status of the partner and the activities of the partnership. Partnerships that hold our common stock, and partners in such partnerships, should consult their own tax advisors regarding the U.S. federal income tax consequences of the Reverse Stock Split.

Each shareholder should consult his, her or its own tax advisor regarding the U.S. federal, state, local and foreign income and other tax consequences of the Reverse Stock Split.

U.S. Holders. The Reverse Stock Split should be treated as a recapitalization for U.S. federal income tax purposes. Therefore, except as described below with respect to cash in lieu of fractional shares, no gain or loss will be recognized upon the Reverse Stock Split. Accordingly, the aggregate tax basis in the common stock received pursuant to the Reverse Stock Split should equal the aggregate tax basis in the common stock surrendered (excluding the portion of the tax basis that is allocable to any fractional share), and the holding period for the common stock received should include the holding period for the common stock surrendered.

A U.S. holder who receives cash in lieu of a fractional share of our common stock pursuant to the Reverse Stock Split should recognize capital gain or loss in an amount equal to the difference between the amount of cash received and the U.S. holder’s tax basis in the shares of our common stock surrendered that is allocated to such fractional share of our common stock. Such capital gain or loss should be long term capital gain or loss if the U.S. holder’s holding period for our common stock surrendered exceeded one year at the Effective Time. The deductibility of net capital losses by individuals and corporations is subject to limitations.

U.S. Information Reporting and Backup Withholding. Information returns generally will be required to be filed with the Internal Revenue Service (“IRS”) with respect to the receipt of cash in lieu of a fractional share of our common stock pursuant to the Reverse Stock Split in the case of certain U.S. holders. In addition, U.S. holders may be subject to a backup withholding tax (at the current applicable rate of 28%) on the payment of such cash if they do not provide their taxpayer identification numbers in the manner required or otherwise fail to comply with applicable backup withholding tax rules. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be refunded or allowed as a credit against the U.S. holder’s federal income tax liability, if any, provided the required information is timely furnished to the IRS.

12

Non-U.S. Holders. The discussion in this section is addressed to “non-U.S. holders.” A non-U.S. holder is a beneficial owner of our common stock who is a foreign corporation or a non-resident alien individual. Generally, non-U.S. holders will not recognize any gain or loss upon the Reverse Stock Split. In particular, gain or loss will not be recognized with respect to cash received in lieu of a fractional share provided that (a) such gain or loss is not effectively connected with the conduct of a trade or business in the United States (or, if certain income tax treaties apply, is not attributable to a non-U.S. holder’s permanent establishment in the United States), (b) with respect to non-U.S. holders who are individuals, such non-U.S. holders are present in the United States for less than 183 days in the taxable year of the Reverse Stock Split and other conditions are met, and (c) such non-U.S. holders comply with certain certification requirements.

In general, backup withholding and information reporting will not apply to payment of cash in lieu of a fractional share of our common stock to a non-U.S. holder pursuant to the Reverse Stock Split if the non-U.S. holder certifies under penalties of perjury that it is a non-U.S. holder and the applicable withholding agent does not have actual knowledge to the contrary. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be refunded or allowed

Vote Required

The affirmative vote of a majority of the issued and outstanding shares of our common stock is required to approve the Amendment to effect the Reverse Stock Split.

Recommendation of Our Board of Directors

Our Board of Directors recommends a vote “FOR” this proposal to approve an amendment to our Restated Certificate of Incorporation to effect a reverse stock split of our common stock at a ratio to be determined by the Board of Directors between 1-for-2 to 1-for-10 shares. We will vote your proxy accordingly unless you specify a contrary choice.

OTHER BUSINESS TO BE BROUGHT BEFORE THE MEETING

Our Board of Directors knows of no business that will be presented for action at the Special Meeting other than that described in the Notice of Special Meeting of Shareholders and this Proxy Statement. If any other matters should be presented at the Special Meeting upon which a vote may properly be taken, the affirmative vote of the majority of shares voted at the Special Meeting is required for approval, unless otherwise required by law or our Restated Certificate of Incorporation or Amended and Restated Bylaws.

SECURITY OWNERSHIP

OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table presents certain information regarding the beneficial ownership of our common stock as of October 4, 2012, of (i) the only persons known by us to own beneficially more than 5% of our common stock, (ii) each of our current directors and named executive officers (as defined in Item 402(a)(3) of the Exchange Act) and (iii) all of our executive officers and directors as a group. All persons listed have sole voting and investment power with respect to their shares unless otherwise indicated in the applicable footnotes, subject to community property laws, where applicable. For purposes of the table, the number of shares and percent of ownership of outstanding common stock that the named person beneficially owns includes shares of common stock that such person has the right to acquire within 60 days following October 4, 2012 and are deemed to be outstanding, but are not deemed to be outstanding for the purposes of computing the number of shares beneficially owned and percentage of outstanding common stock of any other person.

SHAREHOLDER PROPOSALS FOR 2013 ANNUAL MEETING

We must receive any proposal by a shareholder of Graymark intended to be presented at the 2013 Annual Meeting of Shareholders at our principal executive office no later than December 19, 2012 in accordance with Rule 14a-8 under the Exchange Act for inclusion in Graymark’s proxy statement and form of proxy relating to that meeting.

If a stockholder who wishes to present a proposal at the 2013 Annual Meeting of Shareholders (which is not otherwise submitted for inclusion in the proxy statement in accordance with the preceding paragraph) fails to notify the Company by March 4, 2013 and such proposal is brought before the 2013 Annual Meeting of Shareholders, then under applicable SEC rules, the proxies solicited by management with respect to the 2013 Annual Meeting of Shareholders will confer discretionary voting authority with respect to the stockholder’s proposal on the persons selected by management to vote the proxies. If a stockholder makes a timely notification, the proxies may still exercise discretionary voting authority under circumstances consistent with applicable SEC rules.

15

Any proposal intended to be presented at the 2013 Annual Meeting of Shareholders must also comply with the other requirements of applicable SEC rules. In order to curtail any controversy as to the date on which a proposal was received by Graymark, it is suggested that proponents submit their proposal by certified mail, return receipt requested, or other means, including electronic means, that permit them to prove date of delivery.

EXPENSES AND SOLICITATION

We will bear the expenses of this proxy solicitation, including the cost of preparing and mailing this Proxy Statement and accompanying proxy. These expenses include the charges and expenses of banks, brokerage firms, and other custodians, nominees or fiduciaries for forwarding solicitation material regarding the Special Meeting to beneficial owners of our common stock. Our directors or employees may solicit proxies by mail, telephone, and personal interview or by other means without additional compensation, other than reimbursement for their related out-of-pocket expenses. We may, if appropriate, retain an independent proxy solicitation firm to assist us in soliciting proxies. If we do retain a proxy solicitation firm, we would pay such firm’s customary fees and expenses, and such fees would be expected to be approximately $7,500, plus expenses.

HOUSEHOLDING INFORMATION

Unless we have received contrary instructions, we may send a single copy of this Proxy Statement and Notice of Special Meeting to any household at which two or more shareholders reside if we believe the shareholders are members of the same family. Each shareholder in the household will continue to receive a separate proxy card. This process, known as “householding,” reduces the volume of duplicate information received at any one household and helps to reduce our expenses. However, if shareholders prefer to receive multiple sets of our disclosure documents at the same address this year or in future years, the shareholders should follow the instructions described below. Similarly, if an address is shared with another shareholder and together both of the shareholders would like to receive only a single set of our disclosure documents, the shareholders should follow these instructions:

16

WHERE YOU CAN FIND MORE INFORMATION

We file annual and quarterly reports and other reports and information with the Securities and Exchange Commission. These reports and other information can be inspected and copied at, and copies of these materials can be obtained at prescribed rates from, the Public Reference Section of the Securities and Exchange Commission, Judiciary Plaza, 450 Fifth Street, N.W., Washington, D.C. 20549-1004. We distribute to our shareholders annual reports containing financial statements audited by our independent registered public accounting firm and, upon request, quarterly reports for the first three quarters of each fiscal year containing unaudited financial information. In addition, the reports and other information are filed through Electronic Data Gathering, Analysis and Retrieval (known as “EDGAR”) system and are publicly available on the Securities and Exchange Commission’s site on the Internet, located at http://www.sec.gov. We will provide without charge to you, upon written or oral request, a copy of the reports and other information filed with the Securities and Exchange Commission, as well as copies of this Proxy Statement and accompanying proxy.
