(a) The undersigned Company hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to the Registration Statement to: (i) include any prospectus required by Section 10(a)(3) of the Securities Act;
(ii) reflect in the prospectus any facts or events arising after the effective date of the Registration Statement which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement; and notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of a prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration" table in the effective registration statement; and (iii) include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement, provided however, that provisions (i) and (ii) of this undertaking are inapplicable if the information to be filed thereunder is contained in periodic reports filed by the Company pursuant to the Exchange Act that are incorporated by reference into the Registration Statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post- effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

3

(3) To remove from registration by means of post-effective amendment any of the securities being registered which remains unsold at the termination of the offering.

(b) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the Company has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than director, officer or controlling person in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Company will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(c) The Company hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Company's annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this Registration Statement shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

The purpose of the Greenbriar Corporation 2000 Stock Option Plan (the "Plan") is to assist Greenbriar Corporation, a Nevada corporation (the "Company"), in securing and retaining Key Participants of outstanding ability by making it possible to offer them an increased incentive to join or continue in the service of the Company and to increase their efforts for its welfare through participation or increased participation in the ownership and growth of the Company.

1.2 Definitions.

(a) "Acceleration Event" means any event which in the opinion of the Board of Directors of the Company is likely to lead to changes in control of share ownership of the Company, whether or not such change in control actually occurs.

(b) "Award" means an Option granted to a Key Participant under the Plan.

(f) "Common Stock" means the Common Stock of the Company.

(g) "Fair Market Value" means the closing price of the shares on the American Stock Exchange or other exchange on which the Common Stock is primarily traded on the day on which such value is to be determined or, if no shares were traded on such day, on the next preceding day on which shares were traded, as reported by The Wall Street Journal. If at any time shares of Common Stock are not traded on an exchange or in the over-the-counter market, Fair Market Value shall be the value determined by the Board of Directors or Committee administering the Plan, taking into consideration those factors affecting or reflecting value which they deem appropriate.

The Plan shall be administered by the Compensation Committee (the "Committee") appointed by the Board of Directors consisting solely of two or more Non-Employee Directors, as defined in Rule 16b-3 (see
Section 1.10, below), or in the absence of an appointment of such a Committee, the full Board shall serve as the Committee. Subject to the control of the Board, and without limiting the control over decisions described in Section 1.7, the Committee shall have the power to interpret and apply the Plan and to make regulations for carrying out its purpose. More particularly, the Committee shall determine which Key Participants shall be granted Options and the terms of such grants. When granting Options, the Committee shall designate the Option as either an Incentive Stock Option or a Nonqualified Stock Option. Determinations by the Committee under the Plan (including, without limitation, determinations of the person to receive Awards, the form, amount and timing of such Awards, and the terms and provisions of such Awards and the agreements evidencing same) need not be uniform and may be made by it selectively among persons who receive, or are eligible to receive, Awards under the Plan, whether or not such persons are similarly situated. In serving on the Committee, members thereof shall be considered to be acting in their capacity as members of the Board of Directors and shall be entitled to all rights of indemnification provided by the Bylaws of the Company or otherwise to members of the Board of Directors.

8

1.4 Shares Subject to the Plan.

The total number of shares that may be purchased pursuant to Options under the Plan shall not exceed 500,000 shares of Common Stock. Shares subject to the Options which terminate or expire prior to exercise shall be available for future Awards under the Plan without again being charged against the limitation of 500,000 shares set forth above. Shares issued pursuant to the Plan may be either unissued shares of Common Stock or reacquired shares of Common Stock held in treasury.

1.5 Terms and Conditions of Options.

All Options shall be evidenced by agreements in such form as the Committee shall approve from time to time subject to the provisions of Article II and Article III, as appropriate, and the following provisions:

(a) Exercise Price. The exercise price of the Option shall not be less than the Fair Market Value (as determined by the Committee) of the Common Stock at the time the Option is granted.

(b) Exercise. The Committee shall determine whether the Option shall be exercisable in full at any time during the Term or in cumulative or noncumulative installments during the Term.

(c) Termination of Employment or Contractor Relationship. An Optionee's Option shall expire on the expiration of the Term specified in Section 2.1 or 3.1 as the case may be, or upon the occurrence of such events as are specified in the agreement. In the event of exercise of the Option after termination of employment or contractor relationship, the Optionee may exercise the Option only with respect to the shares which could have been purchased by the Optionee at the date of such termination. However, the Committee may, but is not required to, waive any requirements made pursuant to Section 1.5(b) so that some or all of the shares subject to the Option may be exercised within the time limitation described in this subsection. An Optionee's employment or contractor relationship shall be deemed to terminate on the last date for which he receives a regular wage, salary or contract payment. Whether military, government or other service or other leave of absence shall constitute a termination of employment shall be determined in each case by the Committee at its discretion, and any determination by the Committee shall be final and conclusive. A termination of employment or contractor relationship shall not occur where the Optionee transfers from the Company to one of its Subsidiaries or transfers from a Subsidiary to the Company.

(d) Death or Disability. Upon termination of an Optionee's employment or contractor relationship by reason of death or disability (as determined by the Committee consistent with the definition of
Section 422(c)(7) of the Code), the Option shall expire on the earlier of the expiration of (i) the date specified in the Option which in no event shall be later than 12 months after the date of such termination, or (ii) the Term specified in Section 2.1 or 3.1 as the case may be. The Optionee or his successor in interest, as the case may be, may exercise the Option only as to the shares that could have been purchased by the Optionee at the date of his termination of employment. However, the Committee may, but is not required to, waive any requirements made pursuant to Section 1.5(b) so that some or all of the shares subject to the Option may be exercised within the time limitation described in this subsection.

(e) Payment. Payment for shares as to which an Option is exercised shall be made in such manner and at such time or times as shall be provided in the option agreement, including cash, Common Stock of the Company which was previously acquired by the Optionee, or any combination thereof. The Fair Market Value of the surrendered Common Stock as of the date of exercise shall be determined in valuing Common Stock used in payment for Options.

9

(f) Nontransferability. No Option granted under the Plan shall be transferable other than by will or by the laws of descent and distribution. During the lifetime of the Optionee, an Option shall be exercisable only by the Optionee.

(g) Additional Provisions. Each option agreement may contain such other terms and conditions not inconsistent with the provisions of the Plan, including the award of cash amounts, as the Committee may deem appropriate from time to time.

1.6 Stock Adjustments; Mergers.

(a) Generally. Notwithstanding Section 1.4, in the event the outstanding shares are increased or decreased or changed into or exchanged for a different number or kind of shares or other securities of the Company or of any other corporation by reason of any merger, sale of stock, consolidation, liquidation, recapitalization, reclassification, stock split up, combination of shares, stock dividend, or transaction having similar effect, the total number of shares set forth in Section 1.4 shall be proportionately and appropriately adjusted by the Committee.

(b) Options. Following a transaction described in subsection
(a) above, if the Company continues in existence, the number and kind of shares that are subject to any Option and the option price per share shall be proportionately and appropriately adjusted without any change in the aggregate price to be paid therefor upon exercise of the Option. If the Company will not remain in existence or substantially all of its voting Common Stock and Common Stock will be purchased by a single purchaser or group of purchasers acting together, then the Committee may (i) declare that all Options shall terminate 30 days after the Committee gives written notice to all Optionee's of their immediate right to exercise all Options then outstanding (without regard to limitations on exercise otherwise contained in the Options), or (ii) notify all Optionee's that all Options granted under the Plan shall apply with appropriate adjustments as determined by the Committee to the securities of the successor corporation to which holders of the numbers of shares subject to such Options would have been entitled, or
(iii) take action that is some combination of aspects of (i) and (ii). The determination by the Committee as to the terms of any of the foregoing adjustments shall be conclusive and binding. Any fractional shares resulting from any of the foregoing adjustments under this section shall be disregarded and eliminated.

1.7 Acceleration Event.

If an Acceleration Event occurs in the opinion of the Board of Directors, based on circumstances known to it, the Board of Directors may direct the Committee to declare that any or all Options granted under the Plan shall become exercisable immediately notwithstanding the provisions of the respective agreements granting any such Awards.

1.8 Notification of Exercise.

Options shall be exercised by written notice directed to the Secretary of the Company at the principal executive offices of the Company. Such written notice shall be accompanied by any payment required pursuant to
Section 1.5(e). Exercise by an Optionee's heir or the representative of his estate shall be accompanied by evidence of his authority to so act in form reasonably satisfactory to the Company.

10

1.9 Modification, Extension and Renewal of Awards.

Subject to the terms and conditions and within the limitations of the Plan, the Committee may modify, extend or renew outstanding Awards or accept the surrender of outstanding Awards (to the extent not theretofore exercised) granted under the Plan or under any other plan of the Company or a Subsidiary, and authorize the granting of new Awards pursuant to the Plan in substitution therefor, and the substituted Awards may bear such different or additional terms and conditions as the Committee shall deem appropriate within the limitations of the Plan. Notwithstanding the foregoing, however, no modification of an Award shall, without the consent of the Grantee holding the Award, adversely affect the rights or obligations of such Grantee.

1.10. Compliance with Rule 16b-3.

It is intended that the provisions of the Plan and any Award shall comply in all respects with the terms and conditions of Rule 16b-3 under the Securities Exchange Act of 1934, as in effect on April 1, 1997 and as amended, or any successor provisions, as it relates to persons subject to the reporting requirements of Section 16(a) of such Act. Any agreement granting an Award shall contain such provisions as are necessary or appropriate to assure such compliance. To the extent that any provision hereof is found not to be in compliance with such rule as it relates to such Act, such provision shall be deemed to be modified so as to be in compliance with such rule, or if such modification is not possible, shall be deemed to be null and void, as it relates to such Grantee.

ARTICLE II

INCENTIVE STOCK OPTIONS

2.1 Terms of Incentive Stock Options.

Each Incentive Stock Option granted under the Plan shall be exercisable only during a Term fixed by the Committee; provided, however, that the Term shall end no later than 10 years after the date the Incentive Stock Option is granted.

2.2 Limitation on Options.

The aggregate Fair Market Value of Common Stock (determined at the time the Incentive Stock Option is granted) subject to Incentive Stock Options granted to a Key Participant under all plans of the Key Participant's employer corporation and its Parent or Subsidiary corporations and that become exercisable for the first time by such Key Participant during any calendar year may not exceed $100,000.

2.3 Special Rule for Ten Percent Shareholder.

If at the time an Incentive Stock Option is granted, an participant or owns stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of his employer corporation or of its Parent or any of its Subsidiaries, as determined using the attribution rules of Section 424(d) of the Code, then the terms of the Incentive Stock Option shall specify that the option price shall be at least 110% of the Fair Market Value of the stock subject to the Incentive Stock Option and such Incentive Stock Option shall not be exercisable after the expiration of five years from the date such Incentive Stock Option is granted.

2.4 Interpretation.

In interpreting this Article II of the Plan and the provisions of individual option agreements, the Committee and the Board shall be governed by the principles and requirements of Sections 421, 422 and 425 of the Code, and applicable Treasury Regulations.

11

ARTICLE III

NONQUALIFIED STOCK OPTIONS

3.1 Terms and Conditions of Options.

In addition to the requirements of Section 1.5, each Nonqualified Stock Option granted under the Plan shall be exercisable only during a Term fixed by the Committee.

3.2 Section 83(b) Election.

The Company recognizes that certain persons who receive Nonqualified Stock Options may be subject to restrictions regarding their right to trade Common Stock under applicable securities laws. Such may cause Optionee's exercising such Options not to be taxable under the provisions of Section 83(c) of the Code. Accordingly, Optionee's exercising such Nonqualified Stock Options may consider making an election to be taxed upon exercise of the Option under Section 83(b) of the Code and to effect such election will file such election with the Internal Revenue Service within thirty (30) days of exercise of the Option and otherwise in accordance with applicable Treasury Regulations.

Re: Form S-8 Registration Statement relating to the registration of 500,000 shares of common stock, $0.01 par value of Greenbriar Corporation pursuant to the 2000 Stock Option Plan.

Gentlemen:

We are acting as counsel for Greenbriar Corporation, a Nevada corporation (the "Company"), in connection with the filing under the Securities Act of 1933, as amended, of a Registration Statement for the Company on Form S-8 filed with the Securities and Exchange Commission ("SEC") (the "Registration Statement"), covering an aggregate of 500,000 shares (the "Shares") of common stock, par value $0.01 per share (the "Common Stock"), of the Company which will be issued pursuant to the 2000 Stock Option Plan.

In that connection, we have examined the Form S-8 Registration Statement in the form to be filed with the SEC. We have also examined and are familiar with the originals or authenticated copies of all corporate or other documents, records and instruments that we have deemed necessary or appropriate to enable us to render the opinion expressed below.

We have assumed that all signatures on all documents presented to us are genuine, that all documents submitted to us as originals are accurate and complete, that all documents submitted to us as copies are true and correct copies of the originals thereof, that all information submitted to us was accurate and complete and that all persons executing and delivering originals or copies of documents examined by us were competent to execute and deliver such documents. In addition, we have assumed that the Shares will not be issued for consideration equal to less than the par value thereof and that the form of consideration to be received by the Company for the Shares will be lawful consideration under the Nevada Revised Statutes.

14

Based on the foregoing and having due regard for the legal considerations we deem relevant, we are of the opinion that the Shares, or any portion thereof, when issued as described in the Registration Statement, will be validly issued by the Company, fully paid and nonassessable.

This opinion is limited in all respects to the laws of the United States of America and the general corporation laws of the State of Nevada.

This opinion may be filed as an exhibit to the Registration Statement.

Sincerely,

GLAST, PHILLIPS & MURRAY, P.C.
