SPARKMAN, SECRETARY Midland, Texas May 21, 2004 NATURAL GAS SERVICES GROUP, INC. 2911 South County Road 1260 Midland, Texas 79706 PROXY STATEMENT ANNUAL MEETING OF SHAREHOLDERS TO BE HELD ON JUNE 15, 2004 This proxy statement is being furnished in connection with the solicitation of proxies by the Board of Directors of Natural Gas Services Group, Inc., a Colorado corporation, to be used at an annual meeting of shareholders to be held at the Hilton Hotel, 117 West Wall Avenue, Midland, Texas 79701 on Wednesday, June 15, 2004 at 9:00 a.m., Central Time, and at any adjournment(s) of the meeting. This proxy statement and the accompanying proxy will be mailed to Natural Gas' shareholders on or about May 21, 2004. Any person signing and mailing the enclosed proxy may revoke it at any time before it is voted by: o giving written notice of the revocation to Natural Gas' corporate secretary; o voting in person at the meeting; or o voting again by submitting a new proxy card. Only the latest dated proxy card, including one which a person may vote in person at the meeting, will count. If not revoked, the proxy will be voted at the meeting in accordance with the instructions indicated on the proxy by the shareholder, or, if no instructions are indicated, will be voted FOR the slate of directors described in the proxy and such other matters as may properly come before the meeting. VOTING SECURITIES Voting rights are vested in the holders of Natural Gas' $0.01 par value common stock with each share entitled to one vote. Cumulative voting in the election of directors is not permitted. Only shareholders of record at the close of business on May 12, 2004, are entitled to notice of and to vote at the meeting or any adjournments of the meeting. On May 12, 2004, Natural Gas had 5,368,135 shares of common stock outstanding. ACTIONS TO BE TAKEN AT MEETING The meeting has been called by the Board of Directors of Natural Gas to consider and act upon the following matters: 1 1. the election of two directors to serve until the annual meeting of shareholders to be held in 2006 and the election of one director to serve until the annual meeting of shareholders to be held in 2007, or until their successors are elected and qualify; and 2. the transaction of such other business as may lawfully come before the meeting or at any adjournment(s) of the meeting. The holders of a majority of the outstanding shares of common stock present at the meeting in person or represented by proxy shall constitute a quorum. If a quorum is present, directors are elected by a plurality of the vote, i.e., the candidates receiving the highest number of votes cast in favor of their election will be elected to the Board of Directors. As to all other actions voted on at the meeting, if a quorum is present, the affirmative vote of a majority of the shares represented in person or by proxy at the meeting and entitled to vote on the subject matter shall be the act of the shareholders. Where brokers have not received any instruction from their clients on how to vote on a particular proposal, brokers are permitted to vote on routine proposals but not on nonroutine matters. The absence of votes on nonroutine matters are "broker nonvotes." Abstentions and broker nonvotes will be counted as present for purposes of establishing a quorum, but will have no effect on the election of directors. Abstentions and broker nonvotes on proposals other than the election of directors, if any, will be counted as present for purposes of the other proposals and will count as votes against all other proposals. PROPOSAL NUMBER ONE ELECTION OF DIRECTORS The number of directors on Natural Gas' Board of Directors has been established by the shareholders as seven directors. During 2003 and early 2004, the Board of Directors had several changes. In 2003, Scott W. Sparkman and James T. Grigsby resigned from the Board. As allowed by Colorado law and Natural Gas' Bylaws, the remaining directors filled the two vacancies with Wallace C. Sparkman and William F. Hughes, Jr. In March 2004, Wayne L. Vinson, our Chief Executive Officer and Director, passed away. Mr. Vinson's vacant position on the Board of Directors has not yet been filled. The Board of Directors is divided into three classes with directors serving staggered terms. The following sets forth our current directors listed by class and year in which their terms expire: -------------------------- -------------------------- -------------------------- 2004 2005 2006 ---- ---- ---- -------------------------- -------------------------- -------------------------- Richard L. Yadon Charles G. Curtis William F. Hughes, Jr. (1) Wallace O. Sellers Wallace C. Sparkman (1) Gene A. Strasheim -------------------------- -------------------------- -------------------------- (1) Assumes re-election to the Board of Directors at the Annual Meeting of Shareholders in 2004. 2 Shareholders will be electing three Directors at the meeting. As noted above, Mr. Yadon's term expires at the meeting. The Board has recommended Mr. Yadon for re-election to the Board of Directors to serve for a three year term expiring at the Annual Meeting of Shareholders in 2007. Messrs. Hughes and Sparkman replaced Directors whose terms did not expire until 2006. Colorado law provides that the term of a director, who is elected by the remaining directors to fill a vacancy, expires at the next annual meeting of shareholders. Consequently, Messrs. Hughes' and Sparkman's terms expire at the Annual Meeting of Shareholders in 2004. The Board has recommended Messrs. Hughes and Sparkman for re-election to the Board of Directors to serve for a two year term expiring at the Annual Meeting of Shareholders in 2006. The persons named in the enclosed form of Proxy will vote the shares represented by such Proxy for the election of the three nominees for director named above. If, at the time of the meeting, any of these nominees shall become unavailable for any reason, which event is not expected to occur, the persons entitled to vote the Proxy will vote for such substitute nominee or nominees, if any, as they determine in their sole discretion. If elected, Richard L. Yadon will hold office until the annual meeting of shareholders to be held in 2007, or until his successor has been duly elected or appointed or until his earlier death, resignation or removal. If elected, William F. Hughes and Wallace C. Sparkman will hold office until the annual meeting of shareholders to be held in 2006, or until their successors are duly elected or appointed or until their earlier death, resignation or removal.

Natural Gas also reimburses its directors for accountable expenses incurred on Natural Gas' behalf. We typically schedule a Board meeting in conjunction with our annual meeting of shareholders. Although we do not have a formal policy on the matter, we expect our directors to attend each annual meeting, absent a valid reason, such as illness or a schedule conflict. Last year, all seven of the individuals then serving as director attended our annual meeting of shareholders.

At its discretion, the administrator of the plan may determine the persons to whom options may be granted and the terms upon which such options will be granted. All officers, employees and directors are eligible to participate in the plan.

Messrs. Curtis, Hughes, Sellers, Strasheim and Yadon are members of our Audit Committee. Our independent accountants are responsible for performing an independent audit of our consolidated financial statements in accordance with auditing standards generally accepted in the United States of America and issuing an independent accountants' report on such financial statements. The Audit Committee reviews with management our consolidated financial statements; reviews with the independent accountants their independent accountants' report; and reviews the activities of the independent accountants. The Audit Committee selects our independent accountants each year. The Audit Committee also considers the adequacy of our internal controls and accounting policies. The chairman and members of the Audit Committee are all independent directors of our Board of Directors within the meaning of Section 121(A) of the listing standards of the American Stock Exchange. The Audit Committee has reviewed and discussed the audited financial statements with management of Natural Gas. The Audit Committee has discussed with our independent auditors the matters required to be discussed by SAS 61. In addition, the Audit Committee has received the written disclosures and letter from our independent accountants required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees), as may be modified or supplemented, and has discussed with the independent accountants matters pertaining to their independence. The Audit Committee also considered whether the additional services unrelated to audit services performed by HEIN + ASSOCIATES LLP were compatible with maintaining their independence in performing their audit services. Based upon the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in our Annual Report on Form 10-KSB for 2003 for filing with the Securities and Exchange Commission. The Audit Committee and Board of Directors has also selected HEIN + ASSOCIATES LLP as our independent accountants for the fiscal year ending December 31, 2004. The Audit Committee has adopted an amended written Audit Committee Charter that has been adopted by our Board of Directors and is attached hereto as Exhibit A. Respectfully submitted by the Audit Committee, Gene A. Strasheim, Chairman William F. Hughes Richard L. Yadon Charles G. Curtis Wallace O. Sellers 18 PRINCIPAL ACCOUNTANT FEES AND SERVICES During 2003 and 2002, we paid the following fees to our principal accountants: 2003 2002 -------- -------- Audit Fees $ 75,749 $ 43,691 Audit Related Fees 0 0 Tax Fees 18,391 15,468 All Other Fees 7,965 77,078 -------- -------- $102,105 $136,237 ======== ======== To help assure independence of the independent auditors, the Audit committee has established a policy whereby all audit, review, attest and non-audit engagements of the principal auditor or other firms must be approved in advance by the Audit Committee; provided, however, that de minimis non-audit services may instead be approved in accordance with applicable Securities and Exchange Commission rules. This policy is set forth in our Audit Committee Charter, a copy of which is attached to this proxy statement. Of the fees shown in the table which were paid to our principal accountants in 2003, 92% were approved by the Audit Committee. SEC regulations and company policy did not require pre-approval for non-audit services prior to 2003. 2003 ANNUAL REPORT TO SHAREHOLDERS You may obtain our 2003 Annual Report on Form 10-KSB for the fiscal year ended December 31, 2003 upon written request to Scott W. Sparkman, Secretary, at Natural Gas' principal offices, 2911 South County Road 1260, Midland, Texas 79706. In addition, the exhibits to the Annual Report on Form 10-KSB, as amended, for the fiscal year ended December 31, 2003 may be obtained by any stockholder upon written request to Mr. Sparkman. SHAREHOLDER PROPOSALS Under the rules of the SEC, if a shareholder wants us to include a proposal in our Proxy Statement and form of proxy for presentation at our 2005 Annual Meeting of Shareholders, the proposal must be received by us at our principal executive offices at 2911 South County Road 1260, Midland, Texas 79706 by January 24, 2005. The proposal should be sent to the attention of Secretary of the Company. The SEC also sets forth procedures under which shareholders may make proposals outside of the process described above in order for a shareholder to introduce an item of business at an Annual Meeting of Shareholders. These procedures require that shareholders must submit items of business in writing to 19 the Secretary of the Company at our principal executive offices. We must receive the notice of your intention to propose an item of business at our 2005 Annual Meeting no later than 45 days in advance of the 2005 Annual Meeting if it is being held within 30 days preceding the anniversary date (June 15, 2004) of this year's meeting. For any other meeting, the nomination or item of business must be received by the tenth day following the date of public disclosure of the date of the meeting. These requirements are separate from and in addition to the SEC's requirements described in the first paragraph of this section relating to including a proposal in our proxy statements. In order to curtail controversy as to the date on which a proposal was received by us, it is suggested that proponents submit their proposals by certified mail-return receipt requested. Such proposals must also meet the other requirements established by the Securities and Exchange Commission for shareholder proposals. SHAREHOLDER COMMUNICATIONS WITH THE BOARD OF DIRECTORS Because of Natural Gas' small size, to date we have not developed formal processes by which shareholders may communicate directly with directors. Instead, we believe that our informal process permitting communications to be sent to the board of directors either generally or in care of a corporate officer, has served the shareholders' needs. In view of recently adopted SEC disclosure requirements related to this issue, we expect to review in the coming months whether more specific procedures are required. Until any other procedures are developed and posted on our web site (www.ngsgi.com), any communication to the Board of Directors may be mailed to the Board, in care of the Secretary of the Company, at 2911 South County Road 1260, Midland, Texas 79706. Shareholder's should clearly note on the mailing envelope that the letter is a "Shareholder-Board Communication." All such communications should identify the author as a shareholder and clearly state whether the intended recipients are all members of the board of directors or just certain specified individual directors. The Secretary of the Company will make copies of all such communications and circulate them to the appropriate director or directors. SOLICITATION OF PROXIES The cost of soliciting proxies, including the cost of preparing, assembling and mailing this proxy material to shareholders, will be borne by Natural Gas. Solicitations will be made only by use of the mails, except that, if necessary to obtain a quorum, officers and regular employees of Natural Gas may make solicitations of proxies by telephone or electronic facsimile or by personal calls. Brokerage houses, custodians, nominees and fiduciaries will be requested to forward the proxy soliciting material to the beneficial owners of Natural Gas' shares held of record by such persons and Natural Gas will reimburse them for their charges and expenses in this connection. 20 OTHER BUSINESS Our Board of Directors does not know of any matters to be presented at the meeting other than the matters set forth herein. If any other business should come before the meeting, the person's names in the enclosed proxy card will vote such proxy according to their judgment on such matters.
