SECTION 2. CLOSING DATE. The consummation of the purchase and sale transaction
described herein (the "Closing") shall occur concurrently with the execution and
delivery of this Agreement and the payments required hereunder.

SECTION 3. COMPANY REPRESENTATIONS. The Company represents and warrants to each
Purchaser that:

                           (a) Organization, Standing and Qualification. The
         Company is a corporation duly organized, validly existing and in good
         standing under the laws of the State of Texas and has all the requisite
         power and authority to own or lease and operate its properties and to
         carry on its business as now conducted and as proposed to be conducted.

                           (b) Authorization and Enforceability. The Company has
         all requisite corporate power and authority to enter into and perform
         all its obligations under this Agreement and the Securityholders
         Agreement, to issue the Preferred Stock and the Warrants and to carry
         out the transactions contemplated hereby and thereby. The Company has
         duly and properly taken all actions necessary to authorize it to enter
         into and perform its obligations under this Agreement and the
         Securityholders Agreement, and to consummate the transactions
         contemplated hereby and thereby. This Agreement and the Securityholders
         Agreement are legal, valid and binding obligations of the Company,
         enforceable in accordance with their respective terms, except for the
         effect upon such agreements of bankruptcy, insolvency, reorganization,
         moratorium and other similar laws relating to or affecting the rights
         of creditors generally and of general principles of equity (regardless
         of whether enforcement is sought in a proceeding in equity or at law).

                           (c) Capitalization. The authorized capital stock of
         the Company consists of 15,000,000 shares of Common Stock and
         25,000,000 shares of preferred stock, of which 50,000 shares have been
         designated as the Preferred Stock. Of such shares, 3,104,644 shares of
         Common Stock and 9,161,567 shares of Series C Preferred Stock will be
         issued and outstanding immediately prior to the Closing. The Preferred
         Stock and the Warrants are duly authorized and, when issued and paid
         for pursuant to the terms of this Agreement, will be validly issued,
         fully paid and nonassessable. There are no outstanding subscriptions,
         rights, warrants, options, calls, convertible securities, commitments
         of sale or liens granted or issued by the Company or any of its
         subsidiaries relating to or entitling any person to purchase or
         otherwise to acquire any shares of the capital stock of the Company,
         except as otherwise disclosed on Schedule B annexed hereto.

                           (d) Non-Contravention by Company. Neither the
         execution and delivery of this Agreement or the Securityholders
         Agreement nor the issuance, sale or delivery of the Preferred Stock and
         the Warrants by the Company, nor the performance of the obligations of
         the Company and its securityholders hereunder or thereunder, nor any
         action by the Company contemplated hereunder or thereunder, violates
         any provisions of the Articles of Incorporation or Bylaws of the
         Company, or violates or constitutes a breach of or a default under, or
         would result in the acceleration of or entitle any party to


                                       2
<PAGE>   3


          accelerate (whether after the giving of notice or lapse of time or
          both) any material obligation under, or result in the creation or
          imposition of any lien, charge, pledge, security interest or other
          encumbrance of any kind upon the property or assets (real, personal or
          mixed, tangible or intangible) of the Company pursuant to any
          provision of any material promissory note, security interest, bond,
          mortgage, indenture, lien, claim, charge, right, option, lease,
          agreement, license, pledge, encumbrance, instrument, commitment, law,
          ordinance, regulation, order, arbitration award, judgment or decree to
          which the Company is a party or by which it or any of its properties
          or assets (real, personal or mixed, tangible or intangible) are bound
          which would have a material adverse effect on the Company.

                           (e) Private Offering. The Company agrees that neither
         it, nor anyone acting on its behalf, will offer the Preferred Stock and
         the Warrants so as to bring the issuance and sale of such securities
         within the provisions of Section 5 of the Securities Act of 1933, as
         amended (the "Securities Act"), nor offer any similar securities for
         issuance or sale to, or solicit any offer to acquire any of the same
         from, or otherwise approach or negotiate with respect thereto with,
         anyone if the sale of the Preferred Stock and the Warrants and any such
         securities would be integrated as a single offering for the purposes of
         the Securities Act, including, without limitation, Regulation D
         thereunder.

                           (f) Brokers. The Company has not retained, directly
         or indirectly, any broker or finder or incurred any liability or
         obligation for any brokerage fees or finder's fees with respect to this
         Agreement or the transactions contemplated hereby.

                           (g) Survival of Representations and Warranties. All
         the Company's representations and warranties herein shall survive the
         execution and delivery of this Agreement, any investigation by the
         Purchasers and the issuance of the Preferred Stock and the Warrants.


SECTION 4. INVESTMENT REPRESENTATIONS. Each Purchaser acknowledges that the
Preferred Stock and the Warrants are not being registered under the Act, based,
in part, on reliance that the issuance of the Preferred Stock and the Warrants
are exempt from registration under Section 4(2) of the Act as not involving any
public offering. Each Purchaser further acknowledges that the Company's reliance
on such exemption is predicated, in part, on the several representations set
forth below made by each Purchaser to the Company.

                           (a) Such Purchaser is acquiring the Shares solely for
         such Purchaser's own account, for investment purposes only, and not
         with an intent to sell, or for resale in connection with any
         distribution of all or any portion of the Preferred Stock and the
         Warrants within the meaning of the Act;

                           (b) In evaluating the merits and risks of an
         investment in the Preferred Stock and the Warrants, such Purchaser has
         relied upon the advice of such Purchaser's legal counsel, tax advisors,
         and/or investment advisors;


                                       3
<PAGE>   4


                           (c) Such Purchaser is experienced in evaluating and
         investing in companies such as the Company. In addition, such Purchaser
         has a preexisting business relationship with the Company. As a result
         of such relationship, such Purchaser has access on a regular basis to
         the Company's financial statements and other records and information
         material to the Company's financial condition, operations and
         prospects. Such Purchaser has been given access to all books, records
         and other information of the Company which such Purchaser has desired
         to review and analyze in connection with such Purchaser's purchase of
         the Preferred Stock and the Warrants hereunder.

                           (d) Such Purchaser is aware that an investment in
         securities of a closely held corporation such as the Company is not
         liquid and will require such Purchaser's capital to be invested for an
         indefinite period of time, possibly without return. Such Purchaser has
         no need for liquidity in this investment, has the ability to bear the
         economic risk of this investment, and can afford a complete loss of the
         Purchase Price;

                           (e) Such Purchaser understands that the Preferred
         Stock and the Warrants being purchased hereunder are characterized as
         "restricted securities" under the federal securities laws since the
         Preferred Stock and the Warrants are being acquired from the Company in
         a transaction not involving a public offering and that under such laws
         and applicable regulations such securities may be resold without
         registration under the Act only in certain limited circumstances. Such
         Purchaser represents that such Purchaser is familiar with Rule 144
         promulgated under the Act, as presently in effect, and understands the
         resale limitations imposed thereby and by the Act;

                           (f) At no time was an oral representation made to
         such Purchaser relating to the purchase or was such Purchaser presented
         with or solicited by any leaflet, public or promotional meeting,
         newspaper or magazine article, radio or television advertisement or any
         other form of general advertising relating to the purchase hereunder;
         and

                           (g) Such Purchaser has read and understands the
         restrictions set forth in the Securityholders Agreement.


SECTION 5. STOCK CERTIFICATE LEGEND. Each Purchaser understands and acknowledges
that the certificate evidencing the Preferred Stock purchased by such Purchaser
hereunder (or evidencing any other securities issued with respect thereto
pursuant to any stock split, stock dividend, merger or other form of
reorganization or recapitalization) shall bear, in addition to any other legends
which may be required by this Agreement or applicable state securities laws, the
following legend:

                           "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933, AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR
         SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE
         REGISTRATION STATEMENT AS TO SUCH SECURITIES UNDER SAID ACT OR AN
         OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION OR NO-ACTION LETTER
         ISSUED BY THE SECURITIES AND


                                       4
<PAGE>   5


          EXCHANGE COMMISSION THAT SUCH REGISTRATION IS NOT REQUIRED OR UNLESS
          SOLD PURSUANT TO RULE 144 OF SUCH ACT. THIS SECURITY IS ALSO SUBJECT
          TO ADDITIONAL RESTRICTIONS ON TRANSFER AS SET FORTH IN THE
          SECURITYHOLDERS AGREEMENT, COPIES OF WHICH MAY BE OBTAINED UPON
          REQUEST FROM THE CORPORATION AND ANY SUCCESSOR THERETO."
