                               CERTAIN COVENANTS

a.  [Reserved].

b.  Nasdaq Listing; Reporting Status.  As soon as reasonably possible after the
    --------------------------------
    Closing Date and subject to the waiver in Section 5.e, the Company shall
    file an application for listing of additional shares with Nasdaq covering
    such of the Common Shares as shall not previously have been listed for
    trading on Nasdaq and shall provide evidence of such filing to the Holders.
    The Company shall use its best efforts to obtain the listing, subject to
    official notice of issuance, of such Common Shares and on Nasdaq. So long as
    the Holder beneficially
<PAGE>

    owns any shares of Series F Preferred Stock or Common Shares, the Company
    shall timely file all reports required to be filed with the SEC pursuant to
    Section 13 or 15(d) of the 1934 Act, and the Company shall not terminate its
    status as an issuer required to file reports under the 1934 Act even if the
    1934 Act or the rules and regulations thereunder would permit such
    termination. So long as the Holder beneficially owns any shares of Series D
    Preferred Stock or Common Shares, the company shall timely file all reports
    required to be filed with the SEC pursuant to Section 13 or 15(d) of the
    1934 Act, and the Company shall not terminate its status as an issuer
    required to file reports under the 1934 Act even if the 1934 Act or the
    rules and regulations thereunder would permit such termination.

c.  Rule 144. The Company will use its best efforts to provide to the Holder
    --------
    and/or the Company's transfer agent an opinion of counsel, within 3 business
    days of receipt of a request for such opinion from the Holder or the
    transfer agent, to the effect that the shares of Common Stock issuable upon
    conversion of the Series D Preferred Stock may be resold without
    registration under the 1933 Act pursuant to Rule 144 thereof based upon
    customary representations by or on behalf of the Holder as such
    representations may be reasonably requested by the Company.

d.  Amended and Restated Registration Rights.  The parties hereto agree to enter
    ----------------------------------------
    into the Amended and Restated Registration Rights Agreement as of the
    Effective Date.

e.  Waivers. As of the Effective Date and until the earlier of (i) the Initial
    -------
    Reset Date as defined in the Amended Statement of Resolutions or (ii)
    January 15, 2000, the Holder waives (x) any requirement in the Amended
    Statement of Resolutions or in any related instrument (including Section 5.b
    herein) that the Company reserve a sufficient number of shares of Common
    Stock to permit conversion in full of the outstanding shares of Series D
    Preferred Stock or list such shares with Nasdaq; and (y) any rights Holder
    may have to demand redemption of the Series D Preferred Stock based on
    redemption events, inconvertibility events, repurchase events or events of
    default except those redemption rights that may arise from the Company's
    failure to timely perform its obligations to issue Common Stock upon
    conversion (subject to the limitations in Section 5.f) set forth in Section
    10 of the Statement of Resolutions; provided, however, that if the Closing
    Date does not occur on or before December 8, 1999, the waivers granted
    herein shall expire and cease to be effective.

f.  Agreed Limitation on Conversion.  The Holder agrees that, provided the
    -------------------------------
    Reverse Stock Split Date occurs on or before December 31, 1999, during the
    period commencing with the Reverse Stock Split Date and ending on the
    Trading Day immediately prior to the Initial Reset Date, as those terms are
    defined in the Amended Statement of Resolutions, Holder will not convert
    Series D Preferred Stock into Common Stock in an amount greater than the
    number of shares of Common Stock that the Holder would have had the ability
    to sell pursuant to Rule 144 during such period of time (the "Limitation
    Amount"). Holder also agrees that during the same time period of this
    Section 5.f, the redemption obligations of the Company upon inability to
    convert Series F Preferred Stock into Common Stock and related obligations
    to provide Inconvertibility Notices shall be limited to those instances
    created by the inability of the Company to issue the Limitation Amount of
    Common Stock upon conversion of Series D Preferred Stock.

g.  Call Option.  Until October 13, 2000, the Company shall have the option, but
    -----------
    not the obligation, to repurchase at any time, for a cash payment equal to
    $1,000 per share of Series D Preferred Stock so repurchased, any portion of
    Holder's Series D Preferred Stock that the Company in its sole discretion
    chooses to repurchase, upon 20 days prior written
<PAGE>

    notice of exercise of this call option. This provision shall in no way be
    construed to limit Holder's conversion rights under the Amended Statement of
    Resolutions prior to such repurchase.

h.  Shareholder Approval.  The Company agrees to submit as soon as practicable,
    --------------------
    for purposes of Rule 4460 of the NASDAQ, a proposal for approval by
    shareholders of the Company's Common Stock allowing conversion of Series D
    Preferred Stock in amounts greater than the Maximum Share Amount, as such
    term is defined in the Amended Statement of Resolutions.

i.  Dividend Calculation. Holder agrees that for all dividends due from the
    --------------------
    Effective Date through Closing under the Amended Statement of Resolutions
    and not previously waived as to payment by any holder of Series D
    Convertible Preferred Stock, such dividends shall not be deemed untimely so
    long as they are paid on or before Closing.

    Holder from, any claim made against the Holder by any person for any such
    commission, fee or other compensation. The Company has not and will not pay

    Rule 144 under the 1933 Act, the Company understands and believes that each
    Holder will be entitled to tack the holding period of its Note to the
    holding period of the shares of Series F Preferred Stock issued to such
    holder in exchange for such Note.

j.  Capitalization.  Following the reverse stock split as contemplated by the
    --------------
    Company (based on the number of shares outstanding on September 24, 1999),
    the authorized capital stock of the Company will be (a) 50,000,000 shares of
    Common Stock of which approximately 2,872,262 shares will be outstanding,
    all of which are fully paid and nonassessable; and (b) 5,000,000 shares of
    Preferred Stock, $.01 par value, of which 2,000 shares have been designated
    Series A Convertible Preferred Stock and of which 2,057 shares are
    outstanding, 3,000 shares have been designated Series B Senior Convertible
    Preferred Stock and of which 3,000 shares are outstanding, 300,000 shares
    have been designated Series C Convertible Preferred Stock and of which
    215,799 shares are outstanding, 6,500 shares have been designated Series D
    Convertible Preferred Stock and of which 3,964 shares are outstanding,
    900,000 shares have been designated Series E Convertible Preferred Stock
    ("Series E Preferred Stock") of which 833,333 are outstanding and of which
    6,500 shares will be designated as Series F Convertible Preferred Stock of
    which 3,142 shares will be issued pursuant to this Agreement and the
    Exchange Agreement of even date herewith by and among the company and Willis
    Group, LLC, a Texas limited liability company. As of September 24, 1999, the
    Company had outstanding options, warrants and similar rights, including
    preferred stock convertible into Common Stock, entitling the holders to
    purchase or acquire 25,324,269 shares of Common Stock. Other than as set
    forth in the preceding sentence, the Company does not have outstanding any
    material amount of securities (or obligation to issue any such securities)
    convertible into, exchangeable for or otherwise entitling the holders
    thereof to acquire shares of Common Stock. The Company has duly reserved
    from its authorized and unissued shares of Common Stock the full number of
    shares required for (a) all options, warrants, convertible securities and
    other rights to acquire shares of Common Stock which are outstanding and (b)
    all shares of Common Stock and options and other rights to acquire shares of
    Common Stock which may be issued or granted under the stock option and

   Stock.

                                  SECTION 5.
                               CERTAIN COVENANTS

a.  Restrictive Legends.  (1) The Holder acknowledges and agrees that the
    -------------------
    certificates for the shares of Series F Preferred Stock issued to such
    Holder shall bear restrictive legends in substantially the following form
    (and a stop-transfer order may be placed against transfer of such shares of
    Series F Preferred Stock):

        THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
        UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"). THE
        SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE SOLD,
        TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
        STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OR AN OPINION OF
        COUNSEL THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT.

        THE NUMBER OF SHARES CONSTITUTING THE PORTION OF THE MAXIMUM SHARE
        AMOUNT, AS DEFINED IN THE STATEMENT OF RESOLUTION OF SERIES F
        CONVERTIBLE STOCK (THE "STATEMENT OF RESOLUTION"), ALLOCATED TO THE
        SHARES REPRESENTED BY THIS CERTIFICATE FOR THE PURPOSES OF CONVERSION
        THEREOF IS [NUMBER].

        SECTION 10(B)(3)(A) OF THE STATEMENT OF RESOLUTION PERMITS A HOLDER OF
        THE SECURITIES REPRESENTED BY THIS CERTIFICATE TO CONVERT SUCH
        SECURITIES IN ACCORDANCE WITH THE STATEMENT OF RESOLUTION WITHOUT BEING
        REQUIRED TO SURRENDER THIS CERTIFICATE TO THE COMPANY UNLESS ALL OF THE
        SECURITIES REPRESENTED HEREBY ARE CONVERTED. CONSEQUENTLY, FOLLOWING
        CONVERSION OF ANY OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE, THE
        NUMBER OF SHARES REPRESENTED BY THIS CERTIFICATE MAY BE LESS THAN THE
        NUMBER OF SHARES STATED HEREON. UPON REQUEST OF ANY PROPOSED TRANSFEREE
        OF THIS CERTIFICATE, THE COMPANY WILL PROVIDE CONFIRMATION OF THE NUMBER
        OF SHARES EVIDENCED BY THIS CERTIFICATE.

        STATEMENTS (1) SETTING FORTH THE DESIGNATIONS, PREFERENCES, LIMITATIONS
        AND RELATIVE RIGHTS OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE
        AND (2) DENYING THE PREEMPTIVE RIGHT OF SHAREHOLDERS OF THE COMPANY TO
        ACQUIRE UNISSUED OR TREASURY SHARES OF THE COMPANY ARE SET FORTH IN THE
        ARTICLES OF INCORPORATION OF THE COMPANY ON FILE IN THE OFFICE OF THE
        SECRETARY OF STATE OF THE STATE OF TEXAS. THE COMPANY WILL FURNISH A
        COPY OF SUCH STATEMENTS TO THE RECORD HOLDER OF THIS CERTIFICATE WITHOUT
        CHARGE UPON RECEIPT OF WRITTEN REQUEST THEREFOR DIRECTED TO DEAN H.
        FISHER, EQUALNET PLAZA, 1250 WOOD BRANCH PARK DRIVE, HOUSTON, TEXAS
        77079-1212.

    (2)  The Holder further acknowledges and agrees that until such time as the
         Common Shares issued or issuable have been registered for resale under
         the 1933 Act as contemplated by the Amended and Restated Registration
         Rights Agreement, the certificates for the Common Shares which are not
         so registered may bear a restrictive legend in substantially the
         following form (and a stop-transfer order may be placed against
         transfer of the certificates for the Common Shares):

           The securities represented by this certificate have not been
           registered under the Securities Act of 1933, as amended (the "Act").
           The securities have been acquired for investment and may not be
           resold, transferred or assigned in the absence of an effective
           registration statement for the securities under the Act, or an
           opinion of counsel reasonably satisfactory in form, scope and
           substance to the Company that

<PAGE>

           registration is not required under the Act.

  (3)   Once the Registration Statement required to be filed by the Company has
        been declared effective, thereafter (1) upon request of any Holder the
        Company will substitute certificates without restrictive legend for
        certificates for any Common Shares issued prior to the date such
        Registration Statement is declared effective by the SEC which bear such
        restrictive legend and remove any stop-transfer restriction relating
        thereto promptly, but in no event later than three days after surrender
        of such certificates by such Holder and (2) the Company shall not place
        any restrictive legend on certificates for Conversion Shares issued on
        conversion of or as dividends on the shares of Series F Preferred Stock
        or impose any stop-transfer restriction thereon.

b.  Nasdaq Listing; Reporting Status.  As soon as reasonably possible after the
    --------------------------------
    Closing Date and subject to the waiver in Section 5.e, the Company shall
    file an application for listing of additional shares with Nasdaq covering
    such of the Common Shares as shall not previously have been listed for
    trading on Nasdaq and shall provide evidence of such filing to the Holders.
    The Company shall use its best efforts to obtain the listing, subject to
    official notice of issuance, of such Common Shares and on Nasdaq. So long as
    the Holder beneficially owns any shares of Series F Preferred Stock or
    Common Shares, the Company shall timely file all reports required to be
    filed with the SEC pursuant to Section 13 or 15(d) of the 1934 Act, and the
    Company shall not terminate its status as an issuer required to file reports
    under the 1934 Act even if the 1934 Act or the rules and regulations
    thereunder would permit such termination.

c.  Rule 144.  (1) The Company shall not, directly or indirectly, dispute or
    --------
    otherwise interfere with any claim by a holder of shares of Series F
    Preferred Stock that such holder's holding period of such security (and the
    shares of Common Stock issued upon conversion thereof) for purposes of Rule
    144 under the 1933 Act ("Rule 144") relates back (i.e., tacks) to the
    holding period for the Notes; provided, however, that nothing contained in
    this Section 5.c shall obligate the Company or its legal counsel to take a
    position that is inconsistent with the provisions of applicable law or
    regulations and the administrative and judicial interpretations thereof in
    effect from time to time in the future.

    (2) The Company will use its best efforts to provide to the Holder and/or
        the Company's transfer agent an opinion of counsel, within 3 business
        days of receipt of a request for such opinion from the Holder or the
        transfer agent, to the effect that the shares of Common Stock issuable
        upon conversion of the Series F Preferred Stock may be resold without
        registration under the 1933 Act pursuant to Rule 144 thereof based upon
        customary opinions (which may include an opinion of the Law Offices of
        Brian W Pusch, counsel to the Holder, with respect to the tacking under
        Rule 144 of the holding period of the Notes to that of the Series F
        Preferred Shares and, at the time such opinion is requested by the
        Company, the Company shall pay the Holder $5,000 in cash to cover the
        fees and expenses of obtaining such counsel and opinion) and
        representations by or on behalf of the Holder as such opinions or
        representations may be reasonably requested by the Company.

d.  Amended and Restated Registration Rights.  The parties hereto agree to enter
    ----------------------------------------
    into the Amended and Restated Registration Rights Agreement as of the
    Effective Date.

e.  Waivers.  As of the Effective Date and until the earlier of (i) the Initial
    -------
    Reset Date as defined in the Statement of Resolutions or (ii) January 15,
    2000, the Holder waives (x) any

<PAGE>

    requirement in the Statement of Resolutions or in any related instrument
    (including Section 5.b herein) that the Company reserve a sufficient number
    of shares of Common Stock to permit conversion in full of the outstanding
    shares of Series F Preferred Stock or list such shares with Nasdaq; and (y)
    any rights Holder may have to demand redemption of the Series F Preferred
    Stock based on redemption events, inconvertibility events, repurchase events
    or events of default except those redemption rights that may arise from the
    Company's failure to timely perform its obligations to issue Common Stock
    upon conversion (subject to the limitations in Section 5.f) set forth in
    Section 10 of the Statement of Resolutions; provided, however, that if the
    Closing Date does not occur on or before December 8, 1999, the waivers
    granted herein shall expire and cease to be effective.

f.  Agreed Limitation on Conversion.  The Holder agrees that, provided the
    -------------------------------
    Reverse Stock Split Date occurs on or before December 31, 1999, during the
    period commencing with the Reverse Stock Split Date and ending on the
    Trading Day immediately prior to the Initial Reset Date, as those terms are
    defined in the Statement of Resolutions, Holder will not convert Series F
    Preferred Stock into Common Stock in an amount greater than the number of
    shares of Common Stock that the Holder would have had the ability to sell
    pursuant to Rule 144 during such period of time.

g.  Call Option.  Until October 13, 2000, the Company shall have the option, but
    -----------
    not the obligation, to repurchase at any time, for a cash payment equal to
    $1,000 per share of Series F Preferred Stock so repurchased, any portion of
    Holder's Series F Preferred Stock that the Company in its sole discretion
    chooses to repurchase, upon 20 days prior written notice of exercise of this
    call option. This provision shall in no way be construed to limit Holder's
    conversion rights under the Statement of Resolutions prior to such
    repurchase.

h.  Shareholder Approval.  The Company agrees to submit as soon as practicable,
    --------------------
    for purposes of Rule 4460 of the NASDAQ, a proposal for approval by
    shareholders of the Company's Common Stock allowing conversion of Series F
    Preferred Stock in amounts greater than the Maximum Share Amount, as such
    term is defined in the Statement of Resolutions.

i.  Dividend Calculation.  The Company and Holder agree that dividends on the
    --------------------
    Series F Preferred Stock shall be calculated as specified the Statement of
    Resolutions as if (1) Holder held a certificate in the amount specified in
    Section 1.a as of the Effective Date of this Agreement, and (2) the
    Statement of Resolutions were filed with the Secretary of State of the State
    of Texas as of the Effective Date. Holder agrees that for all dividends due
    from the Effective Date through Closing under the Statement of Resolutions
    and not previously waived as to payment by any holder of Series F
    Convertible Preferred Stock, such dividends shall not be deemed untimely so
    long as they are paid on or before Closing.
