ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         On October 3, 1997, The Willis Group entered into a Note and Warrant
Purchase Agreement (the "Agreement") dated as of October 1, 1997 with the
Issuer and certain of the Issuer's subsidiaries pursuant to which The Willis
Group acquired (i) a 12% covertible secured note due April 1, 1998, payable by
the Issuer, in the original principal amount of $1,000,000 (the "Note") and
(ii) warrants (the "Warrants") exercisable for 200,000 shares of Common Stock
at $1.00 per share, subject to adjustment, for an aggregate purchase price of
$1,000,000.  The transaction was completed on October 3, 1997.  The Willis
Group used funds supplied by a loan from Mr. Mike Willis to purchase the Notes
and the Warrants.

ITEM 4.  PURPOSE OF TRANSACTION.

         The Filing Persons acquired their shares of Common Stock as the first
step in acquiring control of the Issuer and such Filing Persons intend to
acquire additional shares of Common Stock sufficient to control the Issuer, as
further described below.  The Filing Persons currently do not intend to acquire
additional shares materially above 51% of the Company, however, the Filing
Persons intend to review their investment in the Issuer on a continuing basis
and, depending upon the price of the Common Stock, subsequent developments
affecting the Issuer, the Issuer's business and prospects, general stock market
and economic conditions, tax considerations and other factors deemed relevant,
may decide to increase or decrease their investment in the Common Stock of the
Issuer.

         On September 26, 1997, The Willis Group entered into a letter of
intent with the Issuer, among others (the "LOI"), for the purpose of creating a
new company ("Newco") and transferring certain operating network assets to the
Issuer via Newco.  The LOI contemplates the investment by The Willis Group of
approximately $5 million in Common Stock of the Issuer, of which approximately
$1 million has been invested pursuant to the Agreement, and the acquisition
thereby of additional shares of Common Stock as consideration for the
contribution of certain assets and working capital, in the form of loans, to
Newco.  The Filing Persons intend to control the board of directors of the
Issuer as a result of its potential acquisition of additional shares of Common
Stock.  There can be no assurance, however, that the Filing Persons and the
Issuer will complete the transactions contemplated by the LOI.

         Except as set forth above in this Item 4, none of the Filing Persons
nor, to the best of each Filing Person's knowledge, none of the executive
officers or directors of such Filing Persons, as applicable, has any plans or
proposals that relate to or would result in any of the actions specified in
clauses (a) through (j) of Item 4 to Schedule 13D.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

         (a) The Filing Persons beneficially own the right, in the form of
currently exercisable warrants and a convertible note, to acquire 1,200,000
shares of Common Stock of the Issuer, which constitutes 16.3% of the Common
Stock outstanding based on the number of securities outstanding (6,152,000) as
contained in the Issuer's most recent filing on Form 10-K (filed September 29,
1997) and including as outstanding the 1,200,000 shares issuable to The Willis
Group under the Warrants and the Notes.  Such securities were acquired pursuant
to the transactions described in Item 3 hereof.

         (b) The Willis Group has sole voting power and power to dispose of the
shares of Common Stock beneficially owned by the Filing Persons and each of
Messrs. Mike Willis, Mark Willis and Harris, as 47.5%, 47.5% and 5% membership
interest owners, respectively, of The Willis Group, have shared voting and
dispositive power with respect to such shares.

ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
TO SECURITIES OF THE ISSUER

         See Item 4 hereof.

         Pursuant to the Agreement, the Issuer granted certain registration
rights to holders of the Warrants and the Note with respect to shares of Common
Stock acquired upon the exercise of the Warrants, the conversion of the Note
and any shares issued as a dividend or other distribution with respect to, or
in exchange for or in replacement of, such shares.  These rights include
certain demand registration rights in addition to "piggy-back" registration
rights, each as set forth in the Agreement.

ITEM 7.  MATERIAL TO BE FILED AS EXHIBITS

                 3.1.20   ENVIRONMENTAL MATTERS.

                 (a)      Neither any property of any Seller nor the operations
         conducted thereon violate any order of any court or Governmental
         Authority or Environmental Laws which violations could reasonably be
         expected to result in liability in excess of $250,000 or which could
         reasonably be expected to result in remedial obligations in excess of
         $250,000, assuming disclosure to the applicable Governmental Authority
         of all relevant facts, conditions and circumstances, if any,
         pertaining to the relevant property.

                 (b)      Without limitation of clause (a) above, no property
         of any Seller nor the operations currently conducted thereon or by any

         of any Seller, threatened action, suit, investigation, inquiry or
         proceeding by or before any court or Governmental Authority or to any
         remedial obligations under Environmental Laws which could reasonably
         be expected to result in liability in excess of $250,000, or which
         could reasonably be expected to result in remedial obligations in
         excess of $250,000 assuming disclosure to the applicable Governmental
         Authority of all relevant facts, conditions and circumstances, if any,
         pertaining to the relevant property.

                 (c)      All notices, permits, licenses or similar
         authorizations, if any, required to be obtained or filed in connection
         with the operation or use of any and all property of each Seller and
         its Subsidiaries, including but not limited to past or present
         treatment, storage, disposal or release of Hazardous Materials into
         the environment, have been duly obtained or filed, except where the
         failure to so obtain or file would not have a Material Adverse Effect.

                 3.1.21   INTELLECTUAL PROPERTY AND OTHER INTANGIBLE ASSETS.

                 (a)      The Sellers (i) own or have the right to use, free
         and clear of all liens, claims, and restrictions, all patents,
         trademarks, service marks, trade names, and copyrights, and all
         applications, licenses, and rights with respect to the foregoing, and
         all trade secrets, including





                                       15
<PAGE>   16
         know-how, inventions, designs, processes, works of authorship,
         computer programs, and technical data and information (collectively,
         "Intellectual Property") used and sufficient for use in the conduct of
         its business as now conducted and/or as presently proposed to be
         conducted (including, without limitation, the development,
         manufacture, operation, and sale of all products and services sold or
         proposed to be sold by the Sellers during the next 24 months following
         the date of this Agreement) without infringing upon or violating any
         right, lien, or claim of others, including, without limitation, former
         employees and former employers of its past and present employees, and
         (ii) except described in Schedule 3.1.21, is not obligated or under
         any liability whatsoever to make any payments by way of royalties,
         fees, or otherwise to any owner or licensee of, or other claimant to,
         any patent, trademark, service mark, trade name, copyright, or other
         intangible asset, with respect to the use thereof or in connection
         with the conduct of its business or otherwise.

                 (b)      Any and all Intellectual Property of any kind,
         relating to the business of the Sellers, currently being developed, or
         developed in the future, by any employee of the Sellers while in the
         employ of the Sellers shall be the property solely of the Sellers. The
         Sellers have taken security measures to protect the secrecy,
         confidentiality, and value of all Intellectual Property, which
         measures are reasonable and customary in the industry in which the
         Sellers operate. The Sellers' employees and other persons who, either
         alone or in concert with others, developed, invented, discovered,
         derived, programmed, or designed the Intellectual Property (the
         "Technical Employees"), or who have knowledge of or access to
         information about the Intellectual Property, have entered into a
         written agreement with the Sellers, in form and substance satisfactory
         to the Company's management (the "Proprietary Information Agreement")
         regarding ownership and treatment of the Intellectual Property.

                 (c)      Except as described in Schedule 3.1.21,, none of the
         Sellers has received any communications alleging that such Seller has
         violated, or by conducting its business as proposed would violate, any
         of the patents, trademarks, service marks, trade names, copyrights, or
         trade secrets or other proprietary rights of any other Person or
         entity. None of the Sellers' employees is obligated under any contract
         (including licenses, covenants, or commitments of any nature) or other
         agreement, or subject to any judgment, decree, or order of any court
         or administrative agency, that would interfere with the use of such
         employee's best efforts to promote the interests of the Sellers or
         that would conflict with the Sellers' business as presently conducted
         and as proposed to be conducted. Neither the execution nor delivery of
         this Agreement, nor the carrying on of the Sellers' business by the
         employees of the Sellers, nor the conduct of the Sellers' business as
         proposed to be conducted, will conflict with or result in a breach of
         the terms, conditions, or provisions of, or constitute a default
         under, any contract, covenant, or instrument under which any of such
         employees is now obligated. It is not, and will not become, necessary
         to utilize any inventions of any of the Sellers' employees (or people
         the Sellers currently intends to hire) made prior to their employment
         by the Sellers other than those that have been assigned to the Sellers
         pursuant to the Proprietary Information Agreement signed by such
         employee.

                 3.1.22   INSURANCE COVERAGE. The properties of the Sellers are
         insured for the benefit of such Seller in amounts deemed adequate by
         the Company's management against risks usually insured against by
         Persons operating businesses similar to those of the Sellers in the
         localities where such properties are located.

         3.2     REPRESENTATIONS AND WARRANTIES OF PURCHASER. To induce the
Sellers to enter into this Agreement, Purchaser represents and warrants to the
Sellers that:

                 3.2.1    PURCHASE FOR INVESTMENT.

                 (a)      Purchaser is acquiring the Note and Warrants for its
         own account and not with a view to the public resale or distribution
         of all or any part thereof in any transaction which would constitute a
         "distribution" within the meaning of the Securities Act of 1933, as
         amended (the "Securities Act").

                 (b)      Purchaser acknowledges that the Note, the shares of
         Common Stock issuable upon conversion of the Note, the Warrants, and
         the Warrant Shares have not been registered under the Securities Act.

                 (c)      Purchaser is an "accredited investor" within the
         meaning of Rule 501 under Regulation D promulgated under the
         Securities Act, is experienced in evaluating investments in companies
         such as the Company, has such knowledge and experience in financial
         and business matters as to be capable of evaluating the merits and
         risks of its investment and has the ability to bear the entire
         economic risk of its investment. Purchaser has made its own evaluation
         of its investment in the Note and the Warrants, based upon such
         information as is available to it and without reliance upon the
         Company or any other person or entity, and Purchaser agrees that
         neither the Company nor any other person or entity has any obligation
         to furnish any additional information to Purchaser except as expressly
         set forth herein.

                 (d)      Purchaser acknowledges that the Note, the shares of
         Common Stock issuable upon conversion of the Note, the Warrants, and
         the Warrant Shares may not be sold, transferred, pledged,
         hypothecated, or otherwise disposed of without registration under the
         Securities Act or an exemption therefrom, and that in the absence of
         an effective registration statement covering the Note, the shares of
         Common Stock issuable upon conversion of the Note, the Warrants, or
         the Warrant Shares or an available exemption from registration under
         the Securities Act, the Note, the shares of Common Stock issuable upon
         conversion of the Note, the Warrants, and the Warrant Shares must be
         held indefinitely.

                 (e)      Purchaser agrees that the Note, the shares of Common
         Stock issuable upon conversion of the Note, the Warrants, and the
         Warrant Shares shall bear legends in substantially the following form:

<PAGE>   18
                 "THE SECURITIES REPRESENTED HEREBY HAVE BEEN ACQUIRED FOR
                 INVESTMENT AND MAY NOT BE SOLD OR OFFERED FOR SALE OR
                 OTHERWISE TRANSFERRED, EXCEPT PURSUANT TO (I) AN EFFECTIVE
                 REGISTRATION STATEMENT UNDER THE SECURITIES ACT, OR (II) AN
                 APPLICABLE EXEMPTION FROM REGISTRATION UNDER THE SECURITIES
                 ACT. ANY SALE PURSUANT TO CLAUSE (II) OF THE PRECEDING
                 SENTENCE MUST BE ACCOMPANIED BY AN OPINION OF COUNSEL
                 REASONABLY SATISFACTORY TO THE COMPANY TO THE EFFECT THAT SUCH
                 EXEMPTION FROM REGISTRATION IS AVAILABLE IN CONNECTION WITH
                 SUCH SALE."

                 3.2.2    AUTHORIZATION; NO CONFLICT. Purchaser has all
         requisite power and authority to enter into this Agreement and to
         carry out and perform its obligations under the terms of this
         Agreement. This Agreement is a legal, valid, and binding obligation of
         Purchaser. The execution, delivery, and performance of this Agreement
         by Purchaser and the consummation by Purchaser of the transactions
         contemplated hereby will not conflict with or result in a default
         under the terms of any material contract, agreement, obligation,
         commitment, or organizational document applicable to Purchaser.

                                   ARTICLE IV

                                   COVENANTS

         The Sellers covenant and agree (each on its own behalf and on behalf

that the Sellers and their Subsidiaries honor such covenants and agreements.

         4.1     AFFIRMATIVE COVENANTS. So long as any principal or other
amounts due and owing remain outstanding under the Note, the Sellers will at
all times comply with the following covenants:

                 4.1.1    COMPLIANCE WITH LAWS. Each Seller will, and will

         applicable Governmental Requirements.

                 4.1.2    INSURANCE. Each Seller will, and will cause its

         against such liabilities, casualties, risks and contingencies and in
         such types and amounts as is customary in the case of Persons engaged
         in the same or similar businesses and similarly situated. Upon request
         of Purchaser, each Seller will furnish or cause to be furnished to
         Purchaser from time to time a summary of the insurance coverage of
         such Seller in form and





                                       18

         substance satisfactory to Purchaser and if requested will furnish
         Purchaser copies of the applicable policies.

                 4.1.3    PAYMENT OF TAXES AND CLAIMS. Each Seller agrees to
         pay or cause to be paid all taxes, assessments, and other governmental
         charges levied upon any of its assets or those of its Subsidiaries or
         in respect of its or their respective franchises, businesses, income
         or profits, all trade accounts payable in accordance with the
         Company's usual and customary business terms, and all claims for work,
         labor, or materials, which if unpaid might become a lien or charge
         upon any asset of such Seller or any of its Subsidiaries, before the
         same become delinquent, except that (unless and until foreclosure,
         sale or other similar proceedings shall have been commenced) no such
         charge need be paid if being contested in good faith and by
         appropriate measures promptly initiated and diligently conducted if
         (a) such reserve or other appropriate provision, if any, as shall be
         required by GAAP shall have been made therefor, and (b) such contest
         does not have a Material Adverse Effect on the ability of such Seller
         or any of its Subsidiaries to pay any Indebtedness and no material
         assets are in imminent danger of forfeiture.

                      4.1.4    PERFORMANCE OF OBLIGATIONS.

                 (a)      Each Seller will, and will cause its Subsidiaries to,
         use its commercially reasonable efforts to pay, discharge, or
         otherwise satisfy at or before maturity or before they become
         delinquent, as the case may be, all of its obligations of whatever
         nature, except when the amount or validity thereof is currently being
         contested in good faith by appropriate proceedings and reserves, if
         any, as shall be required by GAAP with respect thereto have been
         provided on the books of such Seller or its Subsidiaries, as the case
         may be, and except where the failure to so pay, discharge or satisfy
         such obligations would not have a Material Adverse Effect.

                 (b)      The Sellers will pay the Note according to the
         reading, tenor, and effect thereof.

                 4.1.5    CORPORATE EXISTENCE; PROPERTY. Each Seller (i) will

         properties and the properties of its Subsidiaries used and useful in
         the conduct of their respective businesses to be maintained and kept
         in good condition, repair and working order and will use its
         commercially reasonable efforts to cause to be made all necessary
         repairs, renewals, replacements, betterments and improvements thereto,
         and (iii) will, and will cause each of its Subsidiaries to, qualify
         and remain qualified to conduct business in each jurisdiction where

         or such Subsidiary may require such qualification and where the
         failure to so qualify would have a Material Adverse Effect.

         Subsidiaries shall comply with all applicable Environmental Laws the
         failure to comply with which would have a Material Adverse Effect. If
         any Seller or its Subsidiaries shall receive written notice that there
         exists a violation of Environmental Law with respect to its operations
         or any real property owned, formerly owned, used, or leased thereby,
         which violation could have a Material Adverse Effect, such Seller
         shall immediately notify Purchaser in writing. Furthermore, if any
         Seller or its Subsidiaries shall receive written notice that there
         exists a violation of Environmental Law with respect to its operations
         or any real property owned, formerly owned, used or leased thereby,
         which violation could have a Material Adverse Effect, such Seller
         shall within the time period permitted by the applicable Governmental
         Authority (unless otherwise contested by such Seller in good faith)
         remove or remedy such violation in accordance with all applicable
         Environmental Laws unless the Board of Directors of such Seller
         determines that it would be in the best interest of such Seller to
         delay the remedy of such violation, so long as no Material Adverse
         Effect is suffered by such Seller during such delay.

                 4.1.8    FEES AND EXPENSES.

                 (a)      The Sellers will bear all of their expenses in

         connection with the negotiation of and closing under this Agreement
         and any other Operative Documents and the transactions contemplated
         hereby and thereby (up to a maximum of $25,000), including, without

         or any of the other Operative Documents, or any amendments proposed by
         the Sellers whether or not effected, or in connection with the
         consummation of any future transaction related thereto.

                 4.1.9    BOOKS AND RECORDS; INSPECTION OF PROPERTY. Each

         transactions in relation to its business and activities. Each Seller
         covenants that it will permit any Person

         copies thereof or extracts therefrom and to discuss the affairs,
         finances, and accounts of any of such corporations with the directors,
         officers and independent accountants of such Seller and its

         non-assessable and free from all taxes, liens, and charges with
         respect to the issuance thereof. The Company further covenants that
         during the period within which the Warrants may be exercised, the
         Company will at all times have authorized and reserved a sufficient
         number of shares of Common Stock to permit the exercise of the

         Warrants and/or Warrant Shares that, at any time after the earliest of
         (i) the Conversion Date, (ii) the date on which the Warrants (or any
         portion thereof) are exercised, or (iii) the maturity date of the
         Note, within 60 days after receipt of a written request from the
         Purchaser (the "Initiating Holders"), the Company shall file a
         registration statement (and use its commercially reasonable efforts to
         cause such registration statement to become effective under the
         Securities Act) with respect to the offering and sale or other
         disposition of any number of shares of Common Stock issued upon
         conversion of the Note or Warrant Shares or both (all such securities,
         the "Demand Securities"); provided that the Company may defer its
         obligations under this Section 4.1.11(a) for a period of no more than
         90 days if the Company's Board of Directors adopts a resolution that
         filing such a registration statement would require a public disclosure
         by the Company which disclosure would have material adverse
         consequences for the Company, such as a disclosure regarding a pending
         material acquisition by the Company; provided further that once such
         information has been publicly disclosed, then the Company shall
         promptly proceed to fulfill its obligations under this Section
         4.1.11(a). The Company shall continuously maintain the effectiveness
         of such registration statement for the lesser of (i) 180 days after
         the effective date of the registration statement or (ii) the
         consummation of the distribution by the holders of the Demand
         Securities covered by such registration statement (the "Termination
         Date"); provided, however, that if at the Termination Date, the Demand
         Securities are covered by a registration statement which also covers
         other securities and which is required to remain in effect beyond the
         Termination Date, the Company shall maintain in effect such
         registration statement as it relates to the Demand Securities for so
         long as such registration statement (or any subsequent registration
         statement) remains or is required to remain in effect for any of such
         other securities. The Company shall not be required to comply with
         more than two requests for registration pursuant to this Section
         4.1.11(a). In addition, the





                                       21
<PAGE>   22
         Company shall be required to effect up to three Short-form
         Registrations at the request of Purchaser. All expenses of such
         registration shall be borne by the Company, except that underwriting
         commissions and expenses attributable to the Demand Securities and
         fees and disbursements of counsel and other advisors (if any) to the
         Initiating Holders will be borne by such holders requesting that such
         securities be offered.

                 If the Initiating Holders intend to distribute the Demand
         Securities covered by their request by means of an underwriting, they
         shall so advise the Company as a part of their request made pursuant
         to this Section 4.1.11(a). The right of any other holder to
         registration pursuant to this Section 4.1.11(a) shall be conditioned
         upon such holder's participation in such underwriting and the
         inclusion of such holder's Demand Securities in the underwriting
         (unless otherwise mutually agreed by a majority in interest of the
         Initiating Holders and such holder with respect to such participation
         and inclusion) to the extent provided herein. A holder may elect to
         include in such underwriting all or a part of the Demand Securities he
         holds. If other holders of registration rights request inclusion in
         any registration statement pursuant to this Section 4.1.11(a), such
         holders may be included in the underwriting conditioned on their
         acceptance of the further applicable provisions of this Section
         4.1.11(a). The Company shall (together with other holders proposed to
         distribute their securities through such underwriting) enter into an
         underwriting agreement in customary form with a representative of the
         underwriter or underwriters selected for such underwriting by a
         majority in interest of the Initiating Holders. If the representative
         advises the Initiating Holders in writing that marketing factors
         require a limitation on the number of shares to be underwritten, then
         securities held by holders other than the Initiating Holders shall be
         excluded from such registration to the extent so required by such
         limitation.

                 (b)      PIGGY-BACK REGISTRATION RIGHTS. The Company covenants
         and agrees with the Purchaser and any subsequent holders of the Note,
         the Warrants and/or Warrant Shares that, in the event the Company
         proposes to file a registration statement under the Securities Act
         with respect to a firm commitment offering of Common Stock (other than
         in connection with an exchange offer or a registration statement on
         Form S-4 or S-8 or other similar registration statements not available
         to register securities so requested to be included), the Company shall
         in each case give written notice of such proposed filing to the
         Purchaser at least 30 days before the earlier of the anticipated or
         the actual effective date of the registration statement and at least
         ten days before the initial filing of such registration statement and
         such notice shall offer to such holders the opportunity to include in
         such registration statement such number of shares of Common Stock
         issued upon conversion of the Note or Warrant Shares or both (the
         "Piggy-back Securities", and together with the securities referred to
         in Section 4.1.11(a) above, the "Registrable Securities") as they may
         request. Holders desiring inclusion of Piggy-back Securities in such
         registration statement shall so inform the Company by written notice,
         given within ten days of the giving of such notice by the Company in
         accordance with the provisions of Section 8.11 hereof. The Company
         shall permit, or shall cause the managing underwriter of a proposed
         offering to permit, the holders of Piggy-back Securities requested to
         be included in the registration to include such securities in the





                                       22
<PAGE>   23
         proposed offering on the same terms and conditions as applicable to
         securities of the Company, if any, included therein for the account of
         any person other than the Company and the holders. Notwithstanding the
         foregoing, if any such managing underwriter shall advise the Company
         in writing that, in its opinion, the distribution of securities by
         holders thereof, including all or a portion of the Piggy-back
         Securities, requested to be included in the registration concurrently
         with the securities being registered by the Company, would materially
         adversely affect the distribution of such securities by the Company
         for its own account, then the holders of the Registrable Securities
         shall delay their offering and sale of the Registrable Securities (or
         the portions thereof so designated by such managing underwriter) for
         such period, not to exceed 120 days, as the managing underwriter shall
         request, provided that if any other securities are included in such
         registration statement for the account of any person other than the
         Company and the holders of Piggy-back Securities, then such
         securities, including the Piggy-back Securities, so included shall be
         apportioned among holders who wish to be included therein pro rata
         according to amounts so requested to be included by each such person.
         No such delay shall in any event impair any right granted hereunder to
         make subsequent requests for inclusion pursuant to the terms of this
         Section 4.1.11(b).  The Company shall continuously maintain in effect
         any registration statement with respect to which the Piggy-back
         Securities have been requested to be included (and so included) for a
         period of not less than 180 days after the effectiveness of such
         registration statement ("Piggy-back Termination Date"); provided,
         however, that if at the Piggy-back Termination Date the Piggy-back
         Securities are covered by a registration statement which is, or is
         required to remain, in effect beyond the Piggy-back Termination Date,
         the Company shall maintain in effect the registration statement as it
         relates to the Piggy-back Securities for so long as such registration
         statement remains or is required to remain in effect for any of such
         other securities. All expenses of such registration shall be borne by
         the Company, except that underwriting commissions and expenses
         attributable to the Piggy- back Securities and fees and distributions
         of counsel and other advisors (if any) to the holders requesting that
         the Piggy-back Securities be offered will be borne by such holders.

                 (c)      OTHER MATTERS. In connection with the registration of
         Registrable Securities in accordance with Sections 4.1.11(a) or (b)
         above, the Company agrees to:

                          (i)     Use its commercially reasonable efforts to
                 register or qualify the Registrable Securities for offer or
                 sale under state securities or Blue Sky laws of such
                 jurisdictions in which the holders of such Registrable
                 Securities shall designate; provided that in no event shall
                 the Company be obligated to qualify to do business in any
                 jurisdiction where it is not now so qualified or to take any
                 action which would subject it to general service of process in
                 any jurisdiction where it is not now so subject, and use its
                 commercially reasonable efforts to do any and all other acts
                 and things which may be necessary or advisable to enable the
                 holders of Registrable Securities to consummate the sale,
                 transfer, or other disposition of such securities in any
                 jurisdiction;





                                       23
<PAGE>   24
                          (ii)    Enter into indemnity and contribution
                 agreements, each in customary form, with each underwriter, if
                 any, and each holder of Registrable Securities included in
                 such registration statement; and, if requested, enter into an
                 underwriting agreement containing customary representations,
                 warranties, covenants, allocation of expenses, and customary
                 closing conditions including, but not limited to, opinions of
                 counsel and accountants' cold comfort letters with any
                 underwriter who participates in the offering of Registrable
                 Securities;

                          (iii)   Pay all expenses in connection with the
                 registration of the Registrable Securities under the
                 Securities Act and compliance with the provisions of clause
                 (i) above, except to the extent otherwise provided in Sections
                 4.1.11(a) and (b); and

                          (iv)    List the Registrable Securities on each
                 securities exchange, if any, on which the Common Stock is
                 listed.

                 In connection with the registration of Registrable Securities
         in accordance with Paragraph (b) above, the holders agree to enter
         into an underwriting agreement containing customary representations,
         warranties, covenants, allocation of expenses (not otherwise
         inconsistent with this Agreement), and customary closing conditions,
         with any underwriter who participates in the offering of Registrable
         Securities.

                 (d)      RESTRICTIONS ON PUBLIC SALE BY THE COMPANY. The
         Company agrees not to effect any public sale or distribution of any
         shares of Common Stock or any securities convertible into or
         exchangeable or exercisable for such shares of Common Stock (or any
         option or other right for such securities), except for any securities
         that may be issued to the holders pursuant to the Note or the Warrants
         during the 15-day period prior to, and during the 60-day period
         beginning on the effective date of any registration statement under
         which the Registrable Securities are registered in accordance with
         Section 4.1.11(a) (other than as part of such registration).

                 (e)      RULE 144. With a view to making available to
         Purchaser the benefits of certain rules of the Securities and Exchange
         Commission (the "Commission") that may permit the sale of Registrable
         Securities to the public without registration, the Company hereby
         covenants and agrees to use its commercially reasonable best efforts
         to: (i) file in a timely manner all reports and other documents
         required to be filed by it under the Securities Act and the Securities
         Exchange Act of 1934, as amended, and the rules and regulations
         adopted by the Commission thereunder necessary to permit sales under
         Rule 144 under the Securities Act, and the Company will take such
         further action to the extent reasonably required from time to time to
         permit the Purchaser to sell Registrable Securities (whether or not
         any such securities have been the subject of a demand or piggy-back
         request under Section 4.1.11(a) and (b) hereof) without registration
         under the Securities Act within the limitation of the exemptions
         provided by (A) Rule 144 under the Securities Act, as such Rule may be
         amended from time to time, or (B) any similar rule or regulation
         hereafter adopted by the Commission





                                       24
<PAGE>   25
         and (ii) promptly furnish Purchaser a copy of all such reports and
         documents upon request. Upon the request of Purchaser, the Company
         will deliver to Purchaser a written statement as to whether it has
         complied with such requirements.

                 (f)      OTHER REGISTRATION RIGHTS. The Company hereby agrees
         that it shall not grant any additional registration rights with
         respect to shares of its Common Stock, warrants to purchase its Common
         Stock or securities convertible into its Common Stock, which are
         inconsistent with the provisions of this Agreement.

                 4.1.12   FURTHER ASSURANCES. Each Seller covenants that it
         shall cooperate with Purchaser and execute such further instruments
         and documents as Purchaser shall reasonably request to carry out to
         the satisfaction of Purchaser the transactions contemplated by this
         Agreement.

         4.2     REPORTING COVENANTS. So long as any principal or other amounts
due and owing under the Note remain outstanding, the Sellers will furnish to
Purchaser:

         other evidence of beneficial ownership of, any Person (other than any

         transaction of purchase, merger or consolidation if (i) (A) the

         (taking into account all liabilities related to such assets) so sold,
         disposed of or conveyed by the Company and its Subsidiaries after the

         Company and its Subsidiaries taken as a whole (taking into account all
         liabilities related to such assets) as of the end of the most recently
         ended fiscal year of the Company (other than any sales or transfers by
         a Subsidiary to any Seller or to another Subsidiary); provided that
         the Sellers may dispose of assets that are no longer used in or useful

         ordinary course of business and upon fair and reasonable terms no less
         favorable to the Seller or any of its Subsidiaries than would be
         obtained by such Seller or any such Subsidiary in a comparable arm's
         length transaction with a Person who is not an Affiliate of such

         shall not allow any of its Subsidiaries to cause or permit, any of
         their respective properties to be in violation of, or do anything to

         remedial obligations under any Environmental Laws, that could
         reasonably be expected to result in liability in excess of $250,000 or
         which could reasonably be expected to result in remedial obligations
         in excess of $250,000 assuming disclosure to the applicable
         Governmental Authority of all relevant facts, conditions and

                          (c)     terminate any such Plan in a manner which

         or use of materials, supplies, or other property, or the rendering of
         services, if such contract (or any related document) provides that
         payment for such materials, supplies or other property, or the use
         thereof or payment for such services, shall be subordinated to any

                               CONVERSION RIGHTS

         5.1     CONVERSION RIGHTS. The Note shall be convertible into Common
Stock as follows:

                 5.1.1    CONVERSION AT HOLDER'S OPTION. Subject to the
         provisions of Section 5.2 hereof, the holder of the Note shall have
         the right at such holder's option, at any time and from time to time
         after the date of issuance of the Note and without the payment of any
         additional consideration, to convert the Note, in whole or in part,
         into fully paid and nonassessable shares of Common Stock at the
         Conversion Price (as defined in Section 5.1.2 below) in effect on the
         Conversion Date (as defined in Section 5.1.3 below) upon the terms
         hereinafter set forth.

                 5.1.2    NUMBER OF SHARES. In the event of a conversion
         pursuant to Sections 5.1.1 and 5.2, the Note shall be converted into
         such number of shares of Common Stock as is determined by dividing (x)
         $1,000,000 (plus accrued and unpaid interest on the portion of the
         Note so converted through the Conversion Date) by (y) the Conversion
         Price in effect on the Conversion Date. If less than the full
         principal amount of the Note is converted, the accrued and unpaid
         interest shall be calculated on a pro rata basis. The "Conversion
         Price" shall be the lesser of (i) $1.00 per share of Common Stock (the
         "Initial Conversion Price") and (ii) 85% of the Current Market Price,
         as defined in Section 5.1.6 below, on the Conversion Date. Such
         Initial Conversion Price shall be subject to adjustment in order to
         adjust the number of shares of Common Stock into which the Note is
         convertible, as hereinafter provided.

                 5.1.3    MECHANICS OF CONVERSION. The holder of the Note may
         exercise the conversion right specified in Section 5.1.1 by
         surrendering to the Company or any transfer agent of the Company the
         Note to be converted. If the certificate representing shares of Common
         Stock issuable upon conversion of the Note is to be issued in a name
         other than the name on the face of the Note, such Note shall be
         accompanied by such evidence of the assignment and such evidence of
         the signatory's authority with respect thereto as deemed appropriate
         by the Company or its transfer agent. Conversion shall be deemed to
         have been effected with respect to conversions pursuant to Section
         5.1.1, on the date when delivery of notice of an election to convert
         pursuant to Section 5.1.1 is made, and such applicable date is
         referred to herein as the "Conversion Date." Subject to the provisions
         of Section 5.1.5(f), as promptly as practicable after the Conversion
         Date (and after surrender of the Note to the Company), the Company
         shall issue and deliver to or upon the written order of such holder a
         certificate or certificates for the number of full shares of Common
         Stock to which such holder is entitled upon such conversion, and a
         check or cash with respect to any fractional interest in a share of
         Common Stock, as provided in Section 5.1.4. Subject to the provisions
         of Section 5.1.5(f), the person in whose name the certificate or
         certificates for Common Stock are to be issued shall be deemed to have
         become a holder of record of such Common Stock on the applicable
         Conversion Date. Upon conversion of only a portion of the Note the





                                       32
<PAGE>   33
         Company shall issue and deliver to or upon the written order of the
         holder of the certificate so surrendered for conversion, at the
         expense of the Company, a new Note representing the remaining
         unconverted principal amount of the Note so surrendered.

                 5.1.4    FRACTIONAL SHARES. No fractional shares of Common
         Stock or scrip shall be issued upon conversion of the Note. The number
         of full shares of Common Stock issuable upon conversion thereof shall
         be computed on the basis of the aggregate principal amount of the Note
         to be converted. Instead of any fractional shares of Common Stock
         which would otherwise be issuable upon conversion of the Note, the
         Company shall pay a cash adjustment in respect of such fractional
         interest in an amount equal to that fractional interest of the then
         Current Market Price, as defined in Section 5.1.6 below.

                 5.1.5    CONVERSION PRICE AND NUMBER OF SHARES ADJUSTMENTS.
         The Initial Conversion Price shall be subject to adjustment from time
         to time as follows:

                          (a)     Common Stock Issued at Less Than the
                 Conversion Price. If the Company shall issue any Common Stock,
                 other than Excluded Stock, without consideration or for
                 consideration per share less than the lower of (1) the Initial
                 Conversion Price in effect immediately prior to such issuance
                 and (2) the Current Market Price, the Initial Conversion Price
                 in effect immediately prior to each such issuance shall
                 immediately (except as otherwise expressly provided below) be
                 reduced to the price that is equivalent to such consideration
                 received by the Company upon such issuance; provided that this
                 Section 5.1.5(a) shall expire and be of no force and effect
                 after April 1, 1998.

                                  (i)      Issuance for Cash. In the case of
                          the issuance of Common Stock for cash, the amount of
                          the consideration received by the Company shall be
                          deemed to be the amount of the cash proceeds received
                          by the Company for such Common Stock before deducting
                          therefrom any discounts, commissions, taxes or other
                          expenses allowed, paid or incurred by the Company for
                          any underwriting or otherwise in connection with the
                          issuance and sale thereof.

                                  (ii)     Consideration Other Than Cash. In
                          the case of the issuance of Common Stock (otherwise
                          than upon the conversion of shares of capital stock
                          or other securities of the Company) for a
                          consideration in whole or in part other than cash,
                          including securities acquired in exchange therefor
                          (other than securities that by their terms are
                          exchangeable for such Common Stock), the
                          consideration other than cash shall be deemed to be
                          the fair value thereof as determined in good faith by
                          the Board of Directors, irrespective of any
                          accounting treatment; provided that such fair value
                          as determined by the Board of Directors shall not
                          exceed the aggregate Current Market Price of the

                          the Board of Directors authorizes the issuance of
                          such shares.

                                  (iii)    Options and Convertible Securities.

                                  shall be deemed to have been issued at the
                                  time such options, warrants or rights were
                                  issued and for a consideration equal to the
                                  consideration (determined in the manner
                                  provided in Sections 5.1.5(a)(i) and (ii)
                                  above), if any, received by the Company upon
                                  the issuance of such options, warrants or
                                  rights plus the minimum purchase price
                                  provided in such options, warrants or rights
                                  for the Common Stock covered thereby;

                                  the subsequent conversion or exchange
                                  thereof, shall be deemed to have been issued
                                  at the time such securities were issued or
                                  such options, warrants or rights were issued
                                  and for a consideration equal to the
                                  consideration if any, received by the Company
                                  for any such securities and related options,

                                  consideration (determined in the manner
                                  provided in Sections 5.1.5(a)(i) and (ii)
                                  above), if any, to be received by the Company
                                  upon the conversion or exchange of such
                                  securities, or upon the exercise of any
                                  related options, warrants or rights to
                                  purchase or acquire such convertible or

                                        (C)     on any change in the number of
                                  shares of Common Stock deliverable upon
                                  exercise of any such options, warrants or
                                  rights or conversion or exchange of such

                                  securities or any change in the consideration
                                  to be received by the Company upon such
                                  exercise, conversion or exchange, including,
                                  but not limited to, a change resulting from
                                  the anti-dilution provisions thereof, the
                                  Conversion Price as then in effect shall
                                  forthwith be readjusted to such Conversion
                                  Price as would have been obtained had an
                                  adjustment been made upon the issuance of
                                  such options, warrants or rights not
                                  exercised prior to such change, or of such
                                  convertible or exchangeable securities not
                                  converted or exchanged prior to such change,
                                  upon the basis of such change;

                                        (D)     on the expiration or
                                  cancellation of any such options, warrants or
                                  rights, or the termination of the right to
                                  convert or exchange such convertible or
                                  exchangeable securities, if the Initial
                                  Conversion Price shall have been adjusted
                                  upon the issuance thereof, the Initial
                                  Conversion Price shall forthwith be
                                  readjusted to such Initial Conversion Price
                                  as would have been obtained had an adjustment
                                  been made upon the issuance of such options,
                                  warrants, rights or such convertible or
                                  exchangeable securities on the basis of the
                                  issuance of only the number of shares of
                                  Common Stock actually issued upon the
                                  exercise of such options, warrants or rights,
                                  or upon the conversion or exchange of such
                                  convertible or exchangeable securities; and

                                        (E)     if the Initial Conversion Price
                                  shall have been adjusted upon the issuance of
                                  any such options, warrants, rights or
                                  convertible or exchangeable securities, no
                                  further adjustment of the Conversion Price
                                  shall be made for the actual issuance of
                                  Common Stock upon the exercise, conversion or
                                  exchange thereof.

                 In addition to the adjustments set forth above, the Initial
                 Conversion Price shall be immediately reduced on a pari passu
                 basis with the conversion, exercise, or strike price of any
                 other derivative securities of the Company whether now
                 outstanding or hereafter issued.

                          (b)     Excluded Stock. "Excluded Stock" shall mean
                 (i) shares of Common Stock issued or reserved for issuance by
                 the Company upon exercise of warrants outstanding on the date
                 hereof, other than warrants described in Schedule 5.1.5
                 hereto, (ii) shares of Common Stock issued or reserved for
                 issuance by the Company as a stock dividend payable in shares
                 of Common Stock, or upon any subdivision or split-up of the
                 outstanding shares of Common Stock, each of which is subject
                 to the provisions of Section 5.1.5(c) below, (iii) shares of
                 Common Stock issued to Purchaser or any holder of the Note or
                 the Warrants, or (iv) grants of options and shares of Common
                 Stock issuable or issued thereunder pursuant to the Company's
                 stock option plans existing on the date hereof. All shares of
                 Excluded Stock which





                                       35
<PAGE>   36
                 the Company has reserved for issuance shall be deemed to be
                 outstanding for all purposes of computations under Section
                 5.1.5(a).

                          (c)     Stock Dividends, Subdivisions,
                 Reclassifications or Combinations. If the Company shall (i)
                 declare a dividend or make a distribution on its Common Stock
                 in shares of its Common Stock, (ii) subdivide or reclassify
                 the outstanding shares of Common Stock into a greater number
                 of shares, or (iii) combine or reclassify the outstanding
                 Common Stock into a smaller number of shares, the Initial
                 Conversion Price in effect at the time of the record date for
                 such dividend or distribution or the effective date of such
                 subdivision, combination or reclassification shall be
                 proportionately adjusted so that the holder of the Note
                 surrendered for conversion after such date shall be entitled
                 to receive the number of shares of Common Stock which he would
                 have owned or been entitled to receive had the Note been
                 converted immediately prior to such date. Successive
                 adjustments in the Initial Conversion Price shall be made
                 whenever any event specified above shall occur.

                          (d)     Other Distributions. In case the Company
                 shall fix a record date for the making of a distribution to
                 all holders of shares of its Common Stock (i) of shares of any
                 class other than its Common Stock or (ii) of evidences of
                 Indebtedness of the Company or any Subsidiary or (iii) of
                 assets (excluding cash dividends or distributions, and
                 dividends or distributions referred to in 5.1.5(c) above), or
                 (iv) of rights or warrants (excluding those referred to in
                 Section 5.1.5(a) above), in each case the Initial Conversion
                 Price in effect immediately prior thereto shall be reduced
                 immediately thereafter to the price determined by dividing (A)
                 an amount equal to the difference resulting from (1) the
                 number of shares of Common Stock outstanding on such record
                 date multiplied by the Initial Conversion Price per share on
                 such record date, less (2) the fair market value (as
                 determined by the Board of Directors, whose determination
                 shall be conclusive) of said shares or evidences of
                 indebtedness or assets or rights or warrants to be so
                 distributed, by (B) the number of shares of Common Stock
                 outstanding on such record date. Such adjustment shall be made
                 successively whenever such a record date is fixed. In the
                 event that such distribution is not so made, the Initial
                 Conversion Price then in effect shall be readjusted, effective
                 as of the date when the Board of Directors determines not to
                 distribute such shares, evidences of indebtedness, assets,
                 rights or warrants, as the case may be, to the Initial
                 Conversion Price which would then be in effect if such record
                 date had not been fixed.

                          (e)     Rounding of Calculations; Minimum Adjustment.
                 All calculations under this Section 5.1.5 shall be made to the
                 nearest cent or to the nearest one thousandth (1/1000th) of a
                 share, as the case may be. Any provision of this Section 5.1.5
                 to the contrary notwithstanding, no adjustment in the Initial
                 Conversion Price shall be made if the amount of such
                 adjustment would be less than $0.05, but any such amount shall
                 be carried forward and an adjustment with respect thereto
                 shall be made at the time of and together with any subsequent
                 adjustment which, together with such





                                       36
<PAGE>   37
                 amount and any other amount or amounts so carried forward,
                 shall aggregate $0.05 of more; provided that if the events
                 giving rise to such adjustments occur within three months of
                 each other, then such adjustments shall be calculated as if
                 the events giving rise to them had occurred simultaneously on
                 the date of the first such event.

                          (f)     Timing of Issuance of Additional Common Stock
                 Upon Certain Adjustments. In any case in which the provisions
                 of this Section 5.1.5 shall require that an adjustment shall
                 become effective immediately after a record date for an event,
                 the Company may defer until the occurrence of such event (i)
                 issuing to the holder of the Note converted after such record
                 date and before the occurrence of such event the additional
                 shares of Common Stock issuable upon such conversion by reason
                 of the adjustment required by such event over and above the
                 shares of Common Stock issuable upon such conversion before
                 giving effect to such adjustment and (ii) paying to such
                 holder any amount of cash in lieu of a fractional share of
                 Common Stock pursuant to Section 5.1.4; provided that the
                 Company upon request shall deliver to such holder a due bill
                 or other appropriate instrument evidencing such holder's right
                 to receive such additional shares, and such cash, upon the
                 occurrence of the event requiring such adjustment.

                 5.1.6    CURRENT MARKET PRICE. The Current Market Price at any
         date shall mean, in the event the Common Stock is publicly traded, the
         average of the daily closing prices per share of Common Stock for five
         consecutive trading days ending one trading day before such date (as
         adjusted for any stock dividend, split, combination or
         reclassification that took effect during such five trading day
         period). The closing price for each day shall be the last reported
         sale price regular way or, in case no such reported sale takes place
         on such day, the average of the last closing bid and asked prices
         regular way, in either case on the principal national securities
         exchange on which the Common Stock is listed or admitted to trading,
         or if not listed or admitted to trading on any national securities
         exchange, the closing sale price for such day reported by The Nasdaq
         Stock Market, if the Common Stock is traded over-the-counter and
         quoted in the National Market System, or if the Common Stock is so
         traded, but not so quoted, the average of the closing reported bid and
         asked prices of the Common Stock as reported by The Nasdaq Stock
         Market or any comparable system, or, if the common stock is not listed
         on The Nasdaq Stock Market or any comparable system, the average of
         the closing bid and asked prices as furnished by two members of the
         National Association of Securities Dealers, Inc.  selected from time
         to time by the Company for that purpose. If the Common Stock is not
         traded in such manner that the quotations referred to above are
         available for the period required hereunder, Current Market Price per
         share of Common Stock shall be deemed to be the fair value per share
         of Common Stock as determined in good faith by the Board of Directors,
         irrespective of any accounting treatment.

                 5.1.7    STATEMENT REGARDING ADJUSTMENTS. Whenever the Initial
         Conversion Price shall be adjusted as provided in Section 5.1.5, the
         Company shall forthwith file, at the office of any transfer agent for
         the Note and Common Stock and at the principal office of the





                                       37
<PAGE>   38
         Company, a statement showing in detail the facts requiring such
         adjustment and the Initial Conversion Price that shall be in effect
         after such adjustment, and the Company shall also cause a copy of such
         statement to be sent by mail, first class postage prepaid, to the
         holder the Note at its address appearing on the Company's records.
         Each such statement shall be signed by the Company's chief financial
         officer. Where appropriate, such copy may be given in advance and may
         be included as part of a notice required to be mailed under the
         provisions of Section 5.1.8.

                 5.1.8    NOTICE TO HOLDERS. In the event the Company shall
         propose to take any action of the type described in clause (i) (but
         only if the action of the type described in clause (i) would result in
         an adjustment in the Initial Conversion Price), (iii) or (iv) of
         Section 5.1.5, or described in Section 5.1.11, the Company shall give
         notice to each holder of the Notes, in the manner set forth in Section
         5.1.7, which notice shall specify the record date, if any, with
         respect to any such action and the approximate date on which such
         action is to take place. Such notice shall also set forth such facts
         with respect thereto as shall be reasonably necessary to indicate the
         effect on the Initial Conversion Price and the number, kind or class
         of shares or other securities or property which shall be deliverable
         upon conversion of the Note. In the case of any action which would
         require the fixing of a record date, such notice shall be given at
         least ten days prior to the date so fixed, and in case of all other
         action, such notice shall be given at least 15 days prior to the
         taking of such proposed action.  Failure to give such notice, or any
         defect therein, shall not affect the legality or validity of any such
         action.

                 5.1.9    TREASURY STOCK. For the purposes of this Section 5.1,
         the sale or other disposition of any Common Stock theretofore held in
         the Company's treasury shall be deemed to be an issuance thereof.

                 5.1.10   COSTS. The Company shall pay all documentary, stamp,
         transfer or other transactional taxes attributable to the issuance or
         delivery of shares of Common Stock upon conversion of the Note;
         provided that the Company shall not be required to pay any federal or
         state income taxes or other taxes which may be payable in respect of
         any transfer involved in the issuance or delivery of any certificate
         for such shares in a name other than that of the holder of the Notes
         in respect of which such shares are being issued.

                 5.1.11   CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE. In
         case of any consolidation with or merger of the Company with or into
         another corporation or other entity, or in case of any sale, lease or
         conveyance to another corporation or other entity of the assets of the
         Company as an entirety or substantially as an entirety, the Note shall
         after the date of such consolidation, merger, sale, lease or
         conveyance be convertible into the number of shares of stock or other
         securities or property (including cash) to which the Common Stock
         issuable (at the time of such consolidation, merger, sale, lease or
         conveyance, as if the Note was then optionally convertible or
         mandatorily convertible, as the case may be) upon conversion of the
         Note would have been entitled upon such consolidation, merger, sale,
         lease or conveyance; and in any such case, if necessary, the
         provisions set forth herein with respect to the rights and





                                       38
<PAGE>   39
         interests thereafter of the holders of the Note (including without
         limitation the definition of Current Market Price) shall be
         appropriately adjusted so as to be applicable, as nearly as may
         reasonably be, to any shares of stock or other securities or property
         thereafter deliverable on the conversion of the Note.

         5.2     LIMITATION ON CONVERSION. So long as the Company satisfies the
continued listing requirements of the Nasdaq National Market, the conversion
rights set forth above in Section 5.1 and the right to exercise the Warrants as
set forth in the Warrant Agreement shall be limited so that, upon conversion of
the Note or exercise of the Warrants or both, the Purchaser's aggregate
ownership of the Company will be less than 20% of the shares of Common Stock
outstanding on the date of issuance of the Note and the Warrants; provided that
such limitation shall cease and this Section 5.2 shall become null and void
upon the approval of the issuance of the Note and the Warrants by the
shareholders of the Company or the National Association of Securities Dealers,
Inc. or upon such other event as shall allow the conversion or exercise or
both, as appropriate, without violating the applicable requirements of the
Nasdaq National Market.

         ERISA Affiliate that a Plan may become a subject of any such
         proceedings, (iii) the aggregate "amount of unfunded benefit
         liabilities" (within the meaning of Section 4001(a)(18) of ERISA)

         Affiliate withdraws from any Multiemployer Plan, or (vi) the Company

                 (l)      the occurrence of an "Event of Default" as defined in
         the Furst Agreement;

then, when any Event of Default described in clause (a), (b), (c), (d), (e),
(i), (j), (k), or (l) above has occurred and shall be continuing, the principal
of the Note and the interest accrued thereon and all other amounts due
hereunder (the "other payments") shall, upon written notice from Purchaser,
forthwith become and be due and payable, if not already due and payable,
without presentment, further demand or other notice of any kind. When any Event
of Default described in clause (f), (g) or (h) above has occurred, then the
principal of the Note, the interest accrued thereon, and the other payments
shall immediately become due and payable, upon the occurrence thereof, without
presentment, demand, or notice of any kind. If any principal, installment of
interest, or other payment is not paid in full on the due date thereof whether
by maturity, or acceleration or any Event of Default has occurred and is
continuing, then the outstanding principal balance of the Note, any overdue
installment of interest (to the extent permitted by applicable law), including
interest accruing after the commencement of any proceeding under any bankruptcy
or insolvency law, and all other payments will bear additional interest from
the due date of such payment, or from and after an Event of Default, at a rate
equal to the lesser of (i) the Highest Lawful Rate or (ii) an amount equal to
the then applicable interest rate on the Note plus 2% per annum (such
applicable rate being referred to as the "Default Rate"), compounded monthly,
until the payment is received or the Event of Default is cured, if permitted,
or waived. If payment of the Note is accelerated, then the outstanding
principal balance thereof shall bear interest at the Default Rate from and
after the Event of Default. The Sellers shall pay to the holder of the Note all
reasonable out-of-pocket costs and expenses, incurred by such holder in any
effort to collect the Note and other payments, including the reasonable
attorneys fees and expenses for services rendered in connection therewith, and
pay interest on such costs and expenses to the extent not paid when demanded at
the Default Rate.

         6.2     SUITS FOR ENFORCEMENT. If any Event of Default specified in
Section 6.1 above has occurred and is continuing, the holder of the Note may
pursue any available remedy to protect and enforce such holder's rights,
including without limitation, instituting a suit in equity or by action at law,
or both, whether for the specific performance of any covenant or agreement
contained in this Agreement or any other Operative Document, or in aid of the
exercise of any power granted in this





                                       41
<PAGE>   42
Agreement or any other Operative Document, or to enforce any other legal or
equitable right or remedy of such holder.

         6.3     INDEMNIFICATION. The Sellers agree, jointly and severally, to
indemnify, defend, and hold Purchaser harmless from, against, and in respect of
any and all claims, demands, losses, costs, expenses, obligations, liabilities,
damages, recoveries, and deficiencies, including interest, penalties and
reasonable attorneys' fees (collectively, "Claims"), that Purchaser shall incur
or suffer, which arise, result from, or relate to (a) any breach of, or failure
by any Seller or any of its Subsidiaries to perform, any of its
representations, warranties, covenants, or agreements in this Agreement or any
other Operative Document or in any schedule, certificate, exhibit, or other
instrument furnished or to be furnished by any Seller or any of its
Subsidiaries hereunder or thereunder, or in the Charter of any Seller or any of
its Subsidiaries or (b) any claims of any applicable Governmental Authority or
other Person arising under any Environmental Law.

         6.4     DELAYS OR OMISSIONS. No failure to exercise or delay in the
exercise of any right, power or remedy accruing to any holder of the Note upon
any breach or default of any Seller or any of its Subsidiaries under this
Agreement or any other Operative Document shall impair any such right, power,
or remedy of such holder nor shall it be construed to be a waiver of any such
breach or default, or an acquiescence therein, or of or in any similar breach
or default hereafter occurring; nor shall any waiver of any single breach or
default be deemed a waiver of any other breach or default theretofore or
thereafter occurring.

         6.5     REMEDIES CUMULATIVE. All remedies, under either this Agreement
or any other Operative Document, by law or otherwise afforded to any holder of
the Note, shall be cumulative and not alternative.

OPERATIVE DOCUMENTS CONSTITUTE THE ENTIRE AGREEMENT BETWEEN THE SELLERS AND
PURCHASER CONCERNING THE MATTERS REFERRED TO HEREIN AND THEREIN, AND SUPERSEDE
ALL PRIOR AGREEMENTS AND UNDERSTANDINGS AMONG THE SELLERS AND PURCHASER
RELATING TO THE SUBJECT MATTER HEREOF AND THEREOF. THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN OR AMONG THE PARTIES. Any conflict or ambiguity between the
terms and provisions of this Agreement and the terms and provisions of any
other Operative Document shall be controlled by the terms and provisions
hereof.

                                       46
<PAGE>   47

         8.10    FURTHER COOPERATION. At any time and from time to time, and at
its own expense, the Sellers shall promptly execute and deliver all such
documents and instruments, and do all such acts and things, as Purchaser may
reasonably request in order to further effect the purposes of this Agreement
and the other Operative Documents.

         8.11    NOTICES. All notices, requests, and other communications to
any party hereunder shall be in writing (including bank wire, telecopy, or
similar teletransmission or writing) and shall be given to such party at its
address or telecopy number set forth on the signature pages hereof or such
other address or telecopy number as such party may hereafter specify by notice
to the other parties.

         8.12    NO WAIVER; REMEDIES CUMULATIVE. No failure or delay on the
part of Purchaser in exercising any right or remedy under this Agreement, the
Note, or any other Operative Document and no course of dealing between the
Sellers and Purchaser shall operate as a waiver thereof, nor shall any single
or partial exercise of any right or remedy under this Agreement, the Note, or
any other Operative Document preclude any other or further exercise thereof or
the exercise of any other right or remedy under this Agreement, the Note, or
any other Operative Document. The rights and remedies expressly provided are
cumulative and not exclusive and any rights or remedies that Purchaser would
otherwise have. No notice to or demand on the Sellers not otherwise required by
this Agreement, the Note, or any other Operative Document in any case shall
entitle the Sellers to any other or further notice or demand in similar or
other circumstances or constitute a waiver of the rights of Purchaser to any
other or further action in any circumstances without notice or demand.

         8.13    EXHIBITS; SCHEDULES. The exhibits and schedules attached to
this Agreement are incorporated herein and shall be considered to be a part of
this Agreement for the purposes stated herein, except that in the event of any
conflict between any of the provisions of such exhibits or schedules and the
provisions of this Agreement, the provisions of this Agreement shall prevail.

         8.14    MAXIMUM INTEREST. It is the intention of the parties hereto to
conform strictly to applicable usury laws and, anything herein to the contrary
notwithstanding, the obligations of the Sellers to Purchaser under this
Agreement and the other Operative Documents shall be subject to the limitation
that payments of interest shall not be required to the extent that receipt
thereof would be contrary to provisions of law applicable to Purchaser limiting
rates of interest which may be contracted for, charged, reserved, received, or
taken by Purchaser. Accordingly, if the transactions contemplated hereby would
be usurious under applicable law (including the Federal and state Laws of the
United States of America, or of any other jurisdiction whose laws may be
mandatorily applicable) with respect to Purchaser then, in that event,
notwithstanding anything to the contrary in this Agreement or any other
Operative Document, it is agreed as follows: (a) the provisions of this Section
8.14 shall govern and control; (b) the aggregate of all consideration which
constitutes interest under applicable law that is contracted for, charged,
received, reserved, or taken under this Agreement or any other Operative
Document, or otherwise in connection with this Agreement or the transactions
contemplated by the Operative Documents by Purchaser shall under no
circumstances exceed the maximum amount of interest allowed by applicable law
(such maximum lawful interest rate, if any, with respect to Purchaser herein
called the "Highest Lawful Rate"), and any excess shall





                                       47
<PAGE>   48
be credited to the Sellers by Purchaser (or, if such consideration shall have
been paid in full, such excess refunded to the Sellers); (c) all sums paid, or
agreed to be paid, to Purchaser for the use, forbearance, and detention of any
indebtedness of the Sellers to Purchaser hereunder or under any other Operative
Document shall, to the extent permitted by applicable law, be amortized,
prorated, allocated, and spread throughout the full term of any such
indebtedness until payment in full so that the actual rate of interest does not
exceed the Highest Lawful Rate; and (d) if at any time the sum of the interest
and all other amounts payable pursuant to this Agreement and the other
Operative Documents that are deemed to be interest under applicable law exceeds
that amount which would have accrued at the Highest Lawful Rate, the interest
and other amounts to accrue to Purchaser pursuant to this Agreement and the
other Operative Documents shall be limited, notwithstanding anything to the
contrary in this Agreement or any other Operative Document, to that amount
which would have accrued at the Highest Lawful Rate, but any subsequent
reductions, as applicable, shall not reduce the interest or other amounts
payable to Purchaser pursuant to this Agreement and the other Operative
Documents below the Highest Lawful Rate until the total amount of interest
accrued pursuant to this Agreement and the other Operative Documents and such
other amounts deemed to be interest equals the amount that would have accrued
to Purchaser if the rate per annum set forth in the Note had at all times been
in effect, plus all other amounts that which would have been received but for
the effect of this Section 8.14. For purposes of Article 5069-1.04, Vernon's
Texas Civil Statutes, as amended, to the extent, if any, applicable to
Purchaser, the Sellers agree that the Highest Lawful Rate shall be the
"indicated (weekly) rate ceiling" as defined in said Article; provided that
Purchaser may also rely, to the extent permitted by applicable laws, on
alternative maximum rates of interest under other laws applicable to Purchaser
if greater. Tex. Rev. Civ. Stat. Ann. Art. 5069, Ch. 15 (which regulates
certain revolving credit loan accounts and revolving tri-party accounts) shall
not apply to this Agreement or any other Operative Document.

                                   EXHIBIT B

                                       TO

                      NOTE AND WARRANT PURCHASE AGREEMENT

                                    FORM OF

                               WARRANT AGREEMENT

         This WARRANT AGREEMENT dated as of October ___, 1997, between EQUALNET
HOLDING CORP., a Texas corporation (the "Company"), and THE WILLIS GROUP, LLC,
a Texas limited liability company ("Willis" and, together with any transferee
of Warrants or Warrant Shares, the "Warrant Holders(s)").

         WHEREAS, Willis, the Company, EqualNet Corporation, Telesource, Inc.,
and EqualNet Wholesale Services, Inc., have entered into a certain Note and
Warrant Purchase Agreement (the "Note Purchase Agreement") dated October ___,
1997; and

         WHEREAS, the Company proposes to issue to Willis as partial
consideration for Willis's entering into the Note Purchase Agreement, common
stock purchase warrants (the "Warrants") to purchase up to 200,000 shares (the
"Warrant Shares") of the Company's common stock, par value $0.01 per share (the
"Common Stock"), each Warrant entitling the holder thereof to purchase one
share of Common Stock.

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein and in the Agreement set forth and for other good and
valuable consideration, the parties hereto agree as follows:

         1.      ISSUANCE OF WARRANTS; FORM OF WARRANT. The Company will issue
and deliver the Warrants to Willis on the Closing Date referred to in the Note
Purchase Agreement. The aggregate number of Warrants to be issued and delivered
shall be 200,000 (subject to further limitation as provided herein). The
Warrants shall be exercisable on or after October ___, 1997. The text of each
Warrant shall be substantially as set forth in the Warrant Certificate attached
as Exhibit A hereto. The Warrants shall be executed on behalf of the Company by
the manual or facsimile signature of the present or any future Chairman of the
Board, President, or Vice President of the Company, attested by the manual or
facsimile signature of the present or future Secretary or an Assistant
Secretary of the Company. A Warrant bearing the manual or facsimile signature
of individuals who were at any time the proper officers of the Company shall
bind the Company notwithstanding that such individuals or any of them shall
have ceased to hold such offices prior to the delivery of such Warrant or did
not hold such offices on the date of this Warrant Agreement.

         Warrants shall be dated as of the date of execution thereof by the
Company either upon initial issuance or upon division, exchange, substitution
or transfer.





<PAGE>   55
         Subject to Article V of the Note Purchase Agreement, the demand and
the piggy-back registration rights set forth in Section 16 hereof may be
exercised at any time during the term of the Warrants.

         2.      REPRESENTATIONS AND WARRANTIES.

         (a)     The Company hereby represents and warrants as follows:

                 (i)      POWER AND AUTHORITY. The Company has all requisite
         corporate power and authority, and has taken all corporate action
         necessary, to execute, deliver and perform this Warrant Agreement, to
         grant, issue, and deliver the Warrants and to authorize and reserve
         for issuance and, upon payment from time to time of the Exercise
         Price, to issue and deliver the shares of Common Stock or other
         securities issuable upon exercise of the Warrants. This Warrant
         Agreement has been duly executed and delivered by the Company.

                 (ii)     RESERVATION, ISSUANCE AND DELIVERY OF COMMON STOCK.
         There have been reserved for issuance, and the Company shall at all
         times keep reserved, out of the authorized and unissued shares of
         Common Stock, a number of shares sufficient to provide for the
         exercise of the rights of purchase represented by the Warrants, and
         such shares, when issued upon receipt of payment therefor or upon a
         net exercise in accordance with the terms of the Warrants and of this
         Warrant Agreement, will be legally and validly issued, fully paid and
         non- assessable and will be free of any preemptive rights of
         shareholders or any restrictions.

         (b)     The Warrant Holder hereby represents and warrants as follows:

                 (i)      ACCREDITED INVESTOR. The Warrant Holder is an
         "accredited investor" within the meaning of Rule 501 under Regulation
         D promulgated under the Securities Act, is experienced in evaluating
         investments in companies such as the Company, has such knowledge and
         experience in financial and business matters as to be capable of
         evaluating the merits and risks of its investment and has the ability
         to bear the entire economic risk of its investment. The Warrant Holder
         has made its own evaluation of its investment in the Warrants, based
         upon such information as is available to it and without reliance upon
         the Company or any other person or entity, and the Warrant Holder
         agrees that neither the Company nor any other person or entity has any
         obligation to furnish any additional information to the Warrant Holder
         except as expressly set forth herein.

         3.      CONDITIONS TO PURCHASE. Willis's obligations hereunder shall
be subject to satisfaction of the following conditions on the Closing Date
referred to in the Note Purchase Agreement:

                 (a)      All corporate proceedings and other legal matters
         incident to the authorization, form and validity of this Warrant
         Agreement and the Warrants and all other legal matters relating to
         this Warrant Agreement, the Warrants and the transactions





                                  Exhibit B-2
<PAGE>   56
         contemplated hereby shall be satisfactory in all respects to Vinson &
         Elkins L.L.P., counsel for Willis, in their reasonable judgment, and
         the Company shall have furnished to such counsel all documents and
         information that they may reasonably request to enable them to pass
         judgment upon such matters.

                 (b)      There shall have been duly tendered to Willis or upon
         the order of Willis a certificate or certificates representing the
         Warrants.

                 (c)      Each of the "Conditions Precedent" set forth in
         Article VII of the Note Purchase Agreement shall have been satisfied.

         4.      REGISTRATION. The Warrants shall be numbered and shall be
registered on the books of the Company (the "Warrant Register") as they are
issued. The Warrants shall be registered initially in such names and such
denominations as Willis has specified to the Company.

         5.      EXCHANGE OF WARRANT CERTIFICATES. Subject to any restriction
upon transfer set forth in this Warrant Agreement, each Warrant certificate may
be exchanged at the option of the Warrant Holder thereof for another
certificate or certificates of different denominations entitling the Warrant
Holder thereof to purchase upon surrender to the Company or its duly authorized
agent a like aggregate number of Warrant Shares as the certificate or
certificates surrendered then entitle such Warrant Holder to purchase. Any
Warrant Holder desiring to exchange a Warrant certificate or certificates shall
make such request in writing delivered to the Company, and shall surrender,
properly endorsed, the certificate or certificates to be so exchanged.
Thereupon, the Company shall execute and deliver to the person entitled thereto
a new Warrant certificate or certificates, as the case may be, as so requested.
Any Warrant issued upon exchange, transfer or partial exercise of the Warrants
shall be the valid obligation of the Company, evidencing the same generic
rights and entitled to the same generic benefits under this Warrant Agreement
as the Warrants surrendered for such exchange, transfer or exercise.

         6.      TRANSFER OF WARRANTS. Subject to the provisions of Section 14
hereof, the Warrants shall be transferrable only on the Warrant Register upon
delivery to the Company of the Warrant certificate or certificates duly
endorsed by the Warrant Holder or by his duly authorized attorney-in-fact or
legal representative, or accompanied by proper evidence of succession,
assignment or authority to transfer. In all cases of transfer by an attorney-
in-fact, the original power of attorney, duly approved, or an official copy
thereof, duly certified, shall be deposited with the Company. In case of
transfer by executors, administrators, guardians or other legal
representatives, duly authenticated evidence of their authority shall be
produced, and may be required to be deposited with the Company in its
discretion. Upon any registration of transfer, the Company shall deliver a new
Warrant or Warrants to the person entitled thereto.





                                  Exhibit B-3
<PAGE>   57
         7.      TERM OF WARRANTS; EXERCISE OF WARRANTS.

         (a)     Each Warrant entitles the Warrant Holder thereof to purchase
one share of Common Stock during the time period and subject to the conditions
set forth in the respective Warrant Certificates at an exercise price of
[$________] per share, subject to adjustment in accordance with Section 12
hereof (the "Exercise Price"). Each Warrant terminates on the fifth anniversary
of the date on which such Warrant becomes exercisable in accordance with its
terms (the "Expiration Date").

         (b)     The Exercise Price and the number of shares issuable upon
exercise of Warrants are subject to adjustment upon the occurrence of certain
events, pursuant to the provisions of Section 12 of this Warrant Agreement.
Subject to the provisions of this Warrant Agreement, each Warrant Holder shall
have the right, which may be exercised as expressed in such Warrants, to
purchase from the Company (and the Company shall issue and sell to such Warrant
Holder) the number of fully paid and nonassessable shares of Common Stock
specified in such Warrants, upon surrender to the Company, or its duly
authorized agent, of such Warrants, with the purchase form on the reverse
thereof duly filled in and signed, and upon payment to the Company of the
Exercise Price, as adjusted in accordance with the provisions of Section 12 of
this Warrant Agreement or upon a net exercise pursuant to this subsection of
this Warrant Agreement, for the number of shares in respect of which such
Warrants are then exercised. The Warrant Holder may (i) pay the Exercise Price
in cash, by certified or official bank check payable to the order of the
Company, or by the surrender to the Company of securities of the Company having
a Market Price equal to the Exercise Price or by the surrender to the Company
of indebtedness owed by the Company pursuant to the Note Purchase Agreement (in
which case the Company will accept such specified unpaid principal amount in
full payment, as if such payment had been made in cash) or (ii) make an
exercise of Warrants for "Net Warrant Shares." The number of Net Warrant Shares
will be determined as described by the following formula: Net Warrant Shares =
[WS x (MP-EP)]/MP. "WS" is the number of Warrant Shares issuable upon exercise
of the Warrants or portion of Warrants in question. "MP" is the Market Price of
the Common Stock on the last trading day preceding the date of the request to
exercise the Warrants. "Market Price" shall mean the then current market price
per share of Common Stock, as determined in paragraph 12.1(e). "EP" shall mean
the Exercise Price.

         Subject to paragraph 7(c) hereof, upon such surrender of Warrants, and
payment of the Exercise Price, with cash or securities, or upon a net exercise
as aforesaid, the Company at its expense shall issue and cause to be delivered
with all reasonable dispatch to or upon the written order of the Warrant Holder
and in such name or names as the Warrant Holder may designate, a certificate or
certificates for the number of full shares of Common Stock so purchased upon
the exercise of such Warrants, together with cash, as provided in Section 12 of
this Warrant Agreement, in respect of any fraction of a share of such stock
otherwise issuable upon such surrender. Such certificate or certificates shall
be deemed to have been issued, and any person so designated to be named therein
shall be deemed to have become a holder of record of such shares, as of the
date of the surrender of such Warrants and payment of the Exercise Price or
receipt of shares by net exercise as aforesaid. The rights of purchase
represented by the Warrants shall be exercisable, at the election





                                  Exhibit B-4
<PAGE>   58
of the Warrant Holders thereof, either in full or from time to time in part
and, in the event that any Warrant is exercised in respect of less than all of
the shares purchasable on such exercise at any time prior to the Expiration
Date, a new certificate evidencing the remaining Warrant or Warrants will be
issued.

         (c)     So long as the Company satisfies the continued listing
requirements of the Nasdaq National Market, the exercise rights set forth above
and the right to convert the Note as set forth in the Note Purchase Agreement
shall be limited so that, upon conversion of the Note or exercise of the
Warrants or both, the Purchaser's aggregate ownership of the Company will be
less than 20% of the shares of Common Stock outstanding on the date of issuance
of the Note and the Warrants; provided that such limitation shall cease and
this Section 7(c) shall become null and void upon the approval of the issuance
of the Note and the Warrants by the shareholders of the Company or the National
Association of Securities Dealers, Inc. or upon such other event as shall allow
the conversion or exercise or both, as appropriate, without violating the
applicable requirements of the Nasdaq National Market.

         8.      COMPLIANCE WITH GOVERNMENT REGULATIONS. The Company covenants
that if any share of Common Stock required to be reserved for purposes of
exercise or conversion of Warrants require, under any federal or state law or
applicable governing rule or regulation of any national securities exchange,
registration with or approval of any governmental authority, or listing on any
such national securities exchange, before such shares may be issued upon
exercise, the Company will use its commercially reasonable efforts to cause
such shares to be duly registered, approved or listed on the relevant national
securities exchange, as the case may be.

         9.      PAYMENT OF TAXES. The Company will pay all documentary stamp
taxes, if any, attributable to the initial issuance of Warrant Shares upon the
exercise of Warrants and any securities issued pursuant to Section 12 hereof;
provided, however, that the Company shall not be required to pay any tax or
taxes which may be payable in respect of any transfer involved in the issue or
delivery of any Warrants or certificates for Warrant Shares and any securities
issued pursuant to Section 12 hereof in a name other than that of the Warrant
Holder of such Warrants.

         10.     MUTILATED OR MISSING WARRANTS. In case any of the Warrants
shall be mutilated, lost, stolen or destroyed, the Company shall issue and
deliver in exchange and substitution for and upon cancellation of the mutilated
Warrant, or in lieu of and in substitution for the Warrant lost, stolen, or
destroyed, a new Warrant of like tenor and representing an equivalent right or
interest.

         11.     RESERVATION OF WARRANT SHARES; PURCHASE AND CANCELLATION OF
WARRANTS. The Company shall at all times reserve, out of the authorized and
unissued shares of Common Stock, a number of shares sufficient to provide for
the exercise of the rights of purchase represented by the Warrants, and the
transfer agent for the Common Stock ("Transfer Agent") and every subsequent
transfer agent for any shares of the Company's capital stock issuable upon the
exercise of any of the rights of purchase aforesaid are hereby irrevocably
authorized and directed at all times until the Expiration Date to reserve such
number of authorized and unissued shares as shall be requisite for





                                  Exhibit B-5
<PAGE>   59
such purpose. The Company will keep a copy of this Warrant Agreement on file
with the Transfer Agent and with every subsequent transfer agent for any shares
of the Company's capital stock issuable upon the exercise of the rights of
purchase represented by the Warrants. The Company will supply the Transfer
Agent and any such subsequent transfer agent with duly executed stock
certificates for such purpose and will itself provide or otherwise make
available any cash which may be issuable as provided by Section 13 of this
Warrant Agreement. The Company will furnish to the Transfer Agent and any such
subsequent transfer agent a copy of all notices of adjustments, and
certificates related thereto, transmitted to each Warrant Holder pursuant to
Section 12.3 hereof. All warrants surrendered in the exercise of the rights
thereby evidenced shall be canceled, and such canceled Warrants shall
constitute sufficient evidence of the number of shares of stock which have been
issued upon the exercise of such Warrants (subject to adjustment as herein
provided). No shares of stock shall be subject to reservation in respect of the
Warrants subsequent to the Expiration Date except to the extent necessary to
comply with the terms of this Warrant Agreement.

         12.     ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The
number and kind of securities purchasable upon the exercise of each Warrant and
the Exercise Price shall be subject to adjustment from time to time upon the
occurrence of certain events, as hereafter defined.

                 12.1.    MECHANICAL ADJUSTMENTS. The number of Warrant Shares
         purchasable upon the exercise of each Warrant and the Warrant Price
         shall be subject to adjustment as follows:

                          (a)     In case the Company shall (i) pay a dividend
                 to holders of Common Stock in shares of Common Stock or make a
                 distribution to holders of Common Stock in shares of Common
                 Stock, (ii) subdivide its outstanding shares of Common Stock
                 into a larger number of shares of Common Stock, (iii) combine
                 its outstanding shares of Common Stock into a smaller number
                 of shares of Common Stock or (iv) issue by reclassification of
                 its shares of Common Stock other securities of the Company
                 (including any such reclassification in connection with a
                 consolidation or merger in which the Company is the surviving
                 corporation), the number of Warrant Shares purchasable upon
                 exercise of each Warrant immediately prior thereto shall be
                 adjusted so that the Warrant Holder shall be entitled to
                 receive the kind and number of Warrant Shares or other
                 securities of the Company which he would have owned or have
                 been entitled to receive after the happening of any of the
                 events described above, had such Warrant been exercised
                 immediately prior to the happening of such event or any record
                 date with respect thereto regardless of whether the Warrants
                 are exercisable at the time of the happening of such event or
                 at the time of any record date with respect thereto. An
                 adjustment made pursuant to this paragraph (a) shall become
                 effective immediately after the effective date of such event
                 retroactive to the record date, if any, for such event.

                          (b)     In case the Company shall issue rights,
                 options, or warrants to holders of its outstanding Common
                 Stock, without any charge to such holders, entitling them to
                 subscribe for or purchase shares of Common Stock at a price
                 per share which is





                                  Exhibit B-6
<PAGE>   60
                 lower at the record date mentioned below than the Exercise
                 Price, then (i) the Exercise in effect immediately prior to
                 such issuance shall immediately be reduced to the price that
                 is equivalent to such consideration received by the Company
                 upon such issuance and (ii) the number of Warrant Shares
                 thereafter purchasable upon the exercise of each Warrant shall
                 be increased in direct proportion to the increase in the
                 number of shares of Common Stock outstanding on a fully
                 diluted basis immediately prior to such issuance; provided
                 that if such shares of Common Stock, options or other
                 convertible securities (other than Excluded Stock (as defined
                 in the Note Purchase Agreement)) are issued for consideration
                 per share less than the Exercise Price at the date of such
                 issue or sale, the number of shares of Common Stock that
                 immediately prior to such issuance the Warrant Holder shall
                 have been entitled to purchase pursuant to this Warrant shall
                 be increased to the greater of (i) that number of shares of
                 Common Stock that immediately prior to such issuance the
                 Warrant Holder shall have been entitled to purchase pursuant
                 to this Warrant multiplied by a fraction, the numerator of
                 which is the Exercise Price and the denominator of which is
                 such consideration per share, and (ii) the number of shares of
                 Common Stock otherwise calculated under this Section 12.1.
                 Such adjustment shall be made whenever such rights, options,
                 or warrants are issued, and shall become effective immediately
                 after the record date for the determination of stockholders
                 entitled to receive such rights, options, or warrants;
                 provided that this Section 12.1(b) shall expire and be of no
                 force and effect on or after April ___, 1998.

                          (c)     In case the Company shall distribute to
                 holders of its shares of Common Stock evidences of its
                 indebtedness or assets (including cash dividends or other cash
                 distributions) or rights, options, or warrants, or convertible
                 or exchangeable securities containing the right to subscribe
                 for or purchase shares of Common Stock (excluding those
                 referred to in paragraph (b) above), then in each case the
                 number of Warrant Shares thereafter purchasable upon the
                 exercise of each Warrant shall be determined by multiplying
                 the number of Warrant Shares theretofore purchasable upon the
                 exercise of each Warrant by a fraction, of which the numerator
                 shall be the then current market price per share of Common
                 Stock (as determined in accordance with paragraph (e) below)
                 on the date of such distribution, and of which the denominator
                 shall be the then current market price per share of Common
                 Stock, less the then fair value (as determined in good faith
                 by the Board of Directors of the Company) of the portion of
                 the assets or evidences of indebtedness so distributed or of
                 such subscription rights, options, or warrants, or of such
                 convertible or exchangeable securities applicable to one share
                 of Common Stock. Such adjustment shall be made whenever any
                 such distribution is made, and shall become effective on the
                 date of distribution retroactive to the record date for the
                 determination of stockholders entitled to receive such
                 distribution.

                          In the event of distribution by the Company to
                 holders of its shares of Common Stock of stock of a subsidiary
                 or securities convertible into or exercisable





                                  Exhibit B-7
<PAGE>   61
                 for such stock, then in lieu of an adjustment in the number of
                 Warrant Shares purchasable upon the exercise of each Warrant,
                 the Warrant Holder, upon the exercise thereof at any time
                 after such distribution, shall be entitled to receive from the
                 Company, such subsidiary, or both, as the Company shall
                 determine, the stock or other securities to which such Warrant
                 Holder would have been entitled if such Warrant Holder had
                 exercised such Warrant immediately prior thereto regardless of
                 whether the Warrants are exercisable at such time, all subject
                 to further adjustment as provided in this subsection 12.1;
                 provided, however, that no adjustment in respect of dividends
                 or interest on such stock or other securities shall be made
                 during the term of a Warrant or upon the exercise of a
                 Warrant; provided further that this Section 12.1(c) shall
                 expire and be of no force and effect on or after April ___,
                 1998.

                          (d)     In case the Company shall sell and issue
                 shares of Common Stock (other than pursuant to rights,
                 options, warrants, or convertible securities initially issued
                 before the date of this Agreement) or rights, options,
                 warrants, or convertible securities containing the right to
                 subscribe for or purchase shares of Common Stock (excluding
                 shares, rights, options, warrants, or convertible securities
                 issued in any of the transactions described in paragraphs (a),
                 (b) or (c) above) at a price per share of Common Stock
                 (determined, in the case of such rights, options, warrants or
                 convertible securities, by dividing (w) the total of the
                 amount received or receivable by the Company (determined as
                 provided below) in consideration of the sale and issuance of
                 such rights, options, warrants, or convertible securities, by
                 (x) the total number of shares of Common Stock covered by such
                 rights, options, warrants, or convertible securities) lower
                 than the Exercise Price in effect immediately prior to such
                 sale and issuance, then (i) the Exercise in effect immediately
                 prior to such issuance shall immediately be reduced to the
                 price that is equivalent to such consideration received by the
                 Company upon such issuance and (ii) the number of Warrant
                 Shares thereafter purchasable upon the exercise of the
                 Warrants shall be increased in direct proportion to the
                 increase in the number of shares of Common Stock outstanding
                 on a fully diluted basis immediately prior to such issuance;
                 provided that if such shares of Common Stock, options or other
                 convertible securities (other than Excluded Stock) are issued
                 for consideration per share less than the Exercise Price at
                 the date of such issue or sale, the number of shares of Common
                 Stock that immediately prior to such issuance the Warrant
                 Holder shall have been entitled to purchase pursuant to this
                 Warrant shall be increased to the greater of (i) that number
                 of shares of Common Stock that immediately prior to such
                 issuance the Warrant Holder shall have been entitled to
                 purchase pursuant to this Warrant multiplied by a fraction,
                 the numerator of which is the Exercise Price and the
                 denominator of which is such consideration per share, and (ii)
                 the number of shares of Common Stock otherwise calculated
                 under this Section 12.1. Such adjustment shall be made
                 successively whenever such as issuance is made; provided that
                 this Section 12.1(d) shall expire and be of no force and
                 effect on or after April ___, 1998. For the purposes of such
                 adjustments, the consideration received or receivable by the





                                  Exhibit B-8
<PAGE>   62
                 Company for rights, options, warrants, or convertible
                 securities shall be deemed to be the consideration received by
                 the Company for such rights, options, warrants, or convertible
                 securities, plus the consideration or premiums stated in such
                 rights, options, warrants, or convertible securities to be
                 paid for the shares of Common Stock covered thereby. In case
                 the Company shall sell and issue shares of Common Stock, or
                 rights, options, warrants, or convertible securities
                 containing the right to subscribe for or purchase shares of
                 Common Stock, for a consideration consisting, in whole or in
                 part, of property other than cash or its equivalent, then in
                 determining the "price per share of Common Stock" and the
                 "consideration received or receivable by the Company" for
                 purposes of the first sentence of this paragraph (d), the
                 Board of Directors shall determine, in its discretion, the
                 fair value of said property.

                          (e)     For the purpose of any computation under
                 paragraphs (b), (c), and (d) of this Section, the current
                 market price per share of Common Stock at any date shall be
                 the average of the daily closing prices of the Company's
                 Common Stock, for five consecutive trading days ending one
                 trading day before the date of such computation. The closing
                 price for each day shall be the last such reported sales price
                 regular way or, in case no such reported sale takes place on
                 such day, the average of the closing bid and asked prices
                 regular way for such day, in each case on the principal
                 national securities exchange on which the shares of Common
                 Stock are listed or admitted to trading or, if not listed or
                 admitted to trading, the average of the closing bid and asked
                 prices of the Common Stock in the over-the-counter market as
                 reported by NASDAQ or any comparable system. In the absence of
                 one or more such quotations, the Board of Directors of the
                 Company shall determine the current market price, in good
                 faith, on the basis of such quotations as it considers
                 appropriate. Notwithstanding the foregoing, for the purpose of
                 any calculation under paragraph (d) above (A) with respect to
                 any issuance of options under the Company's employee or
                 director compensation stock option plans as in effect or as
                 adopted by the Board of Directors of the Company on the date
                 hereof, the term "current market price", in such instances,
                 shall mean the fair market price on the date of the issuance
                 of any such option determined in accordance with the Company's
                 employee compensation stock option plans as in effect or
                 adopted by the Board of Directors of the Company on the date
                 hereof; and (B) with respect to any issuances of Common Stock
                 (or rights, options, warrants, or convertible securities
                 containing the right to subscribe for or purchase shares of
                 Common Stock) in connection with bona fide corporate
                 transactions (other than issuances in such transactions for
                 cash or similar consideration), the term "fair market price"
                 shall mean the fair market price per share as determined in
                 arm's-length negotiations by the Company and such other
                 parties (other than affiliates or subsidiaries of the Company)
                 to such transactions as reflected in the definitive
                 documentation with respect thereto, unless such determination
                 is not reasonably related to the closing market price on the
                 date of such determination.





                                  Exhibit B-9
<PAGE>   63
                          (f)     In any case in which this Section 12.1 shall
                 require that any adjustment in the number of Warrant Shares be
                 made effective as of immediately after a record date for a
                 specified event, the Company may elect to defer until the
                 occurrence of the event the issuing to the holder of any
                 Warrant exercised after that record date the shares of Common
                 Stock and other securities of the Company, if any, issuable
                 upon the exercise of any Warrant over and above the shares of
                 Common Stock and other securities of the Company, if any,
                 issuable upon the exercise of any Warrant prior to such
                 adjustment; provided, however, that the Company shall deliver
                 to such Warrant Holder a due bill or other appropriate
                 instrument evidencing the holder's right to receive such
                 additional shares or securities upon the occurrence of the
                 event requiring such adjustment.

                          (g)     No adjustment in the number of Warrant Shares
                 purchasable hereunder shall be required unless such adjustment
                 would require an increase or decrease of at least one percent
                 (1%) in the number of Warrant Shares purchasable upon the
                 exercise of each Warrant; provided, however, that any
                 adjustments which by reason of this paragraph (g) are not
                 required to be made shall be carried forward and taken into
                 account in any subsequent adjustment. All calculations shall
                 be made to the nearest one-thousandth of a share.

                          (h)     Whenever the number of Warrant Shares
                 purchasable upon the exercise of each Warrant is adjusted, as
                 herein provided, the Warrant Price payable upon the exercise
                 of each Warrant shall be adjusted by multiplying such Warrant
                 Price immediately prior to such adjustment by a fraction, of
                 which the numerator shall be the number of Warrant Shares
                 purchasable upon the exercise of such Warrant immediately
                 prior to such adjustment, and of which the denominator shall
                 be the number of Warrant Shares purchasable immediately.

                          (i)     No adjustment in the number of Warrant Shares
                 purchasable upon the exercise of each Warrant need be made
                 under paragraphs (b), (c) and (d) if the Company issues or
                 distributes to each Warrant Holder the rights, options,
                 warrants, or convertible or exchangeable securities, or
                 evidences of indebtedness or assets referred to in those
                 paragraphs which each Warrant Holder would have been entitled
                 to receive had the Warrants been exercised prior to the
                 happening of such event or the record date with respect
                 thereto regardless of whether the Warrants are exercisable at
                 the time of the happening of such event or at the time of any
                 record date with respect thereto. No adjustment need be made
                 for a change in the par value of the Warrant Shares.

                          (j)     For the purpose of this Section 12.1, the
                 terms "shares of Common Stock" shall mean (i) the class of
                 stock designated as the Common Stock of the Company at the
                 date of this Agreement, or (ii) any other class of stock
                 resulting from successive changes or reclassifications of such
                 shares consisting solely of changes





                                  Exhibit B-10
<PAGE>   64
                 in par value, or from par value to no par value, or from no
                 par value to par value. In the event that at any time, as a
                 result of an adjustment made pursuant to paragraph (a) above,
                 the Warrant Holders shall become entitled to purchase any
                 securities of the Company other than shares of Common Stock,
                 thereafter the number of such other securities so purchasable
                 upon exercise of each Warrant and the Exercise Price of such
                 securities shall be subject to adjustment from time to time in
                 a manner and on terms as nearly equivalent as practicable to
                 the provisions with respect to the Warrant Shares contained in
                 paragraphs (a) through (i), inclusive, above, and the
                 provisions of Section 7 and Section 12.2 through 12.5,
                 inclusive, with respect to the Warrant Shares, shall apply on
                 like terms to any such other securities.

                          (k)     Upon the expiration of any rights, options,
                 warrants, or conversion or exchange privileges, if any thereof
                 shall not have been exercised, the Warrant Price and the
                 number of shares of Common Stock purchasable upon the exercise
                 of each warrant shall, upon such expiration, be readjusted and
                 shall thereafter be such as it would have been had it been
                 originally adjusted (or had the original adjustment not been
                 required, as the case may be) as if (A) the only shares of
                 Common Stock so issued were the shares of Common Stock, if
                 any, actually issued or sold upon the exercise of such rights,
                 options, warrants, or conversion or exchange rights and (B)
                 such shares of Common Stock, if any, were issued or sold for
                 the consideration actually received by the Company upon such
                 exercise plus the aggregate consideration, if any, actually
                 received by the Company for the issuance, sale or grant of all
                 such rights, options, warrants, or conversion or exchange
                 rights whether or not exercised; provided, however, that no
                 such readjustment shall have the effect of increasing the
                 Warrant Price or decreasing the number of Warrant Shares by an
                 amount in excess of the amount of the adjustment initially
                 made with respect to the issuance, sale or grant of such
                 rights, options, warrants, or conversion or exchange rights.

                          (l)     In addition to the adjustments set forth
                 above, the Exercise Price shall be immediately reduced and the
                 number of Warrant Shares shall be immediately increased, in
                 each case, on a pari passu basis with the conversion,
                 exercise, or strike price of any other derivative securities
                 of the Company whether now outstanding or hereafter issued.

                 12.2.    VOLUNTARY ADJUSTMENT BY THE COMPANY. The Company may,
         at its option, at any time during the term of the Warrants, reduce the
         then current Exercise Price to any amount determined appropriate by
         the Board of Directors of the Company.

                 12.3.    NOTICE OF ADJUSTMENT. When the number of Warrant
         Shares purchasable upon the exercise of each Warrant or the Exercise
         Price of such Warrant Shares is adjusted, as herein provided, the
         Company shall promptly mail by first class, postage prepaid, to each
         Warrant Holder notice of such adjustment or adjustments and a
         certificate of a firm of





                                  Exhibit B-11
<PAGE>   65
         independent public accountants selected by the Board of Directors of
         the Company (who may be the regular accountants employed by the
         Company) setting forth the number of Warrant Shares purchasable upon
         the exercise of each Warrant and the Exercise Price of such Warrant
         Shares after such adjustment and setting forth a brief statement of
         the facts requiring such adjustment and setting forth the computation
         by which such adjustment was made. Such certificate, absent manifest
         error, shall be conclusive evidence of the correctness of such
         adjustment.

                 12.4.    PRESERVATION OF PURCHASE RIGHTS UPON MERGER,
         CONSOLIDATION, ETC. In case of any consolidation of the Company with
         or merger of the Company into another person or in case of any sale,
         transfer, or lease to another person of all of or substantially all
         the assets of the Company, the Company or such successor or purchaser,
         as the case may be, shall execute with each Warrant Holder an
         agreement that each Warrant Holder shall have the right thereafter
         upon payment of the Exercise Price in effect immediately prior to such
         action to purchase upon exercise of each Warrant the kind and amount
         of shares and other securities and property which the Warrant Holder
         would have owned or have been entitled to receive after the happening
         of such consolidation, merger, sale, transfer, or lease had such
         Warrant been exercised immediately prior to such action regardless of
         whether the Warrants are exercisable at the time of such action. Such
         agreement shall provide for adjustments, which shall be as nearly
         equivalent as may be practicable to the adjustments provided for in
         this Section 12.  The provisions of this Section 12.4 shall similarly
         apply to successive consolidations, mergers, sales, transfers, or
         leases.

                 12.5.    STATEMENT ON WARRANTS. Even though Warrants
         heretofore or hereafter issued may continue to express the same price
         and number and kind of shares as are stated in the Warrants initially
         issuable pursuant to this Warrant Agreement, the parties understand
         and agree that such Warrants will represent rights consistent with any
         adjustments in the Exercise Price or the number or kind of shares
         purchasable upon the exercise of the Warrants.

         13.     FRACTIONAL INTERESTS. The Company shall not be required to
issue fractional Warrant Shares on the exercise of Warrants. If more than one
Warrant shall be presented for exercise in full at the same time by the same
Warrant Holder, the number of full Warrant Shares which shall be issuable upon
the exercise thereof shall be computed on the basis of the aggregate number of
Warrant Shares purchasable on exercise of the Warrants so presented. If any
fraction of a Warrant Share would, except for the provisions of this Section
13, be issuable on the exercise of any Warrant (or specified portion, thereof),
the Company shall pay an amount in cash equal to the closing price for one
share of the Common Stock on the trading day immediately preceding the date the
Warrant is presented for exercise, multiplied by such fraction.

         14.     REGISTRATION UNDER THE SECURITIES ACT OF 1933. Willis
represents and warrants to the Company that it will not dispose of the Warrant
or Warrant Shares except pursuant to (i) an effective registration statement,
or (ii) an applicable exemption from registration under the Securities





                                  Exhibit B-12
<PAGE>   66
Act of 1933 (the "Act"). In connection with any sale by Willis pursuant to
clause (ii) of the preceding sentence, it shall furnish to the Company an
opinion of counsel reasonably satisfactory to the Company to the effect that
such exemption from registration is available in connection with such sale.

         15.     CERTIFICATE TO BEAR LEGENDS. The Warrants shall be subject to
a stop-transfer order and the certificate or certificates therefor shall bear
the following legend by which each Warrant Holder shall be bound:

         "THE WARRANTS REPRESENTED HEREBY AND THE SECURITIES ISSUABLE UPON
         EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933, AS AMENDED (THE "SECURITIES ACT"), OR THE SECURITIES LAWS OF ANY
         OTHER STATE. THE WARRANTS REPRESENTED HEREBY AND THE SECURITIES
         ISSUABLE UPON EXERCISE HEREOF HAVE BEEN ACQUIRED FOR INVESTMENT AND
         MAY NOT BE SOLD OR OFFERED FOR SALE OR OTHERWISE TRANSFERRED, EXCEPT
         PURSUANT TO (I) AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
         SECURITIES ACT, OR (II) AN APPLICABLE EXEMPTION FROM REGISTRATION
         UNDER THE SECURITIES ACT. ANY SALE PURSUANT TO CLAUSE (II) OF THE
         PRECEDING SENTENCE MUST BE ACCOMPANIED BY AN OPINION OF COUNSEL
         REASONABLY SATISFACTORY TO THE COMPANY TO THE EFFECT THAT SUCH

         17.     NO RIGHTS AS STOCKHOLDERS; NOTICE TO WARRANT HOLDERS. Nothing
contained in this Warrant Agreement or in any of the Warrants shall be
construed as conferring upon the Warrant Holders or their transferees the right
to vote or to receive dividends or to consent or to receive notice as
stockholders in respect of any meeting of stockholders for the election of
directors of the Company or any other matter, or any rights whatsoever as
stockholders of the Company. If, however, at any time prior to the expiration
of the Warrants and prior to their exercise, any of the following events shall
occur:

                 (a)      the Company shall declare any dividend payable in any
         securities upon its shares of Common Stock or make any distribution
         (other than a cash dividend) to the holders of its shares of Common
         Stock; or

                 (b)      the Company shall offer to the holders of its shares
         of Common Stock any additional shares of Common Stock or securities
         convertible into or exchangeable for shares of Common Stock or any
         right to subscribe to or purchase any thereof; or

                 (c)      a dissolution, liquidation, or winding up of the
         Company (other than in connection with a consolidation, merger, sale,
         transfer, or lease or all or substantially all of its property,
         assets, and business as an entirety) shall be proposed,

then in any one or more of said events the Company shall give notice in writing
of such event to the Warrant Holders as provided in Section 20 hereof, with
such notice to be completed at least 15 days prior to the date fixed as a
record date or the date of closing the transfer books for the determination of
the stockholders entitled to such dividend, distribution, or subscription
rights, or for the determination of stockholders entitled to vote on such
proposed dissolution, liquidation or winding up. Such notice shall specify such
record date or the date of closing the transfer books, as the case may be.
Failure to provide or receive such notice or any defect therein or in the
mailing thereof shall not affect the validity of any action taken in connection
with such dividend, distribution, or subscription rights, or such proposed
dissolution, liquidation ,or winding up.

         18.     EXPENSES. The Company shall pay all legal and other reasonable
out-of-pocket expenses of the Warrant Holders and of their counsel (up to a
maximum of $25,000). The Company agrees to reimburse Willis upon demand for its
reasonable out-of-pocket costs and expenses incurred in connection with the
preparation, review, negotiation, execution, and delivery of this Warrant
Agreement and all other related documents.

         19.     RIGHT TO INFORMATION. The Company, in accordance with Section
16(c) above, will provide to all Warrant Holders and to all holders of Warrant
Shares, on a timely basis, copies of all documents and reports delivered to its
shareholders.

or to make any other provisions in regard to matters or questions arising
hereunder which the Company and the Warrant Holder may deem necessary or
desirable and which shall not be inconsistent with the provisions of the
Warrants and which shall not adversely affect the interests of the Warrant
Holders. Any amendment to this Warrant Agreement may be effected with the
consent of Warrant Holders of at least a majority of the total then outstanding
Warrants (for this purpose Warrant Shares shall be deemed to be Warrants in the

Warrants); provided that any amendment which shall have the effect of
materially adversely affecting the interests of any Warrant Holder shall not be
effective with respect to such Warrant Holder if such Warrant Holder shall not
have consented thereto.

         23.     SURVIVAL OF COVENANTS. All covenants and agreements made
herein shall survive the execution and delivery of this Warrant Agreement and
the Warrants and shall remain in force and effect until the Expiration Date of

Warrant Agreement have been inserted for convenience and shall have no
substantive effect.

number of counterparts, each of which so executed shall be deemed to be an
original, but such counterparts together shall constitute but one and the same
instrument.

$3,400,000.00                    HOUSTON, TEXAS                  OCTOBER 1, 1997


         FOR VALUE RECEIVED, after date, without grace, in the manner, on the
dates, and in the amounts so herein stipulated, the undersigned, WILLIS GROUP,
L.L.C., a Texas limited liability company,  acting by and through its duly
authorized officers ("Maker"), promises to pay to the order of MICHAEL T.
WILLIS ("Payee"), whose address is 4400 Post Oak Parkway, Suite 1130, Houston,
Texas, 77027-3413 Harris County, Texas, the sum of THREE MILLION FOUR HUNDRED
THOUSAND AND NO/100 DOLLARS ($3,400,000.00) in lawful money of the United
States of America, which shall be legal tender, in payment of all debts and
dues, public and private, at the time of payment and to pay interest thereon
from date until maturity at a rate of eight percent (8%) per annum, payable as
stipulated herein.

         This note is due and payable in full on or before October 1, 1998.

         This note may be prepaid in whole or in part at any time without
penalty; provided, however, that all payments received by Payee from Maker upon
this note shall first be applied to the payment of accrued but unpaid interest,
with the balance thereof to be applied to the reduction of the outstanding
principal of this note.  All prepayments shall be applied to the outstanding
principal balance of this note in the inverse order of maturity.

         Whenever any payment to be made under this note shall be stated to be
due on a Saturday, Sunday or legal holiday for commercial banks under the laws
of the State of Texas, then such payment shall be made on the next succeeding
business day and such extension of time shall in such case be included in the
computation of payment of interest hereunder.

         In addition to all principal and accrued interest on this note, Maker
agrees to pay (a) all reasonable costs and expenses incurred by all owners and
holders of this note in collecting this note through probate, reorganization,
bankruptcy or any other proceeding, (b) reasonable attorneys' fees when and if
this note is placed in the hands of an attorney for collection after default,
and (c) the reasonable attorneys' fees, costs and expenses incurred by Payee in
connection with the preparation and filing of the agreements and documents
contemplated herein.

         Unless otherwise provided by law, Maker and any and all co-makers,
endorsers, guarantors and sureties severally waive notice (including, but not
limited to, notice of protest, notice of dishonor and notice of intent to
accelerate and notice of acceleration), demand, presentment for payment,
protest and the filing of suit for the purpose of fixing liability and consent
that the time of payment hereof may be extended and re-extended from time to
time without notice to them or any of them, and each agrees that his, her or
its liability on or with respect to this note shall not be affected by any
release of or change in any security at any time existing or by any failure to
perfect or to maintain perfection of any lien on or security interest in any
such security.

         Maker warrants and represents to Payee, and to all other owners and
holders of any indebtedness evidenced hereby, that the loan evidenced by this
Note is and shall be solely for business, commercial or agricultural purposes
and not primarily for personal, family or household use.  Maker acknowledges
that the loan evidenced by this Note is specifically exempted under Section
226.3(a) of Regulation Z issued by the Board of Governors of the Federal
Reserve System and under the Truth-in-Lending Act and that no disclosures are
required to be given under such regulations and federal laws in connection with
this Note.

         It is agreed that time is of the essence of this agreement, and that
in the event of default in the payment of any installment of principal or
interest when due the holder hereof may declare the unpaid principal balance
plus all accrued but unpaid interest due thereon immediately due and payable
without notice, and failure to exercise said option shall not constitute a
waiver on the part of the holder of the right to exercise the same at any other
time.
<PAGE>   2
         In the event of default in the making of any payment herein provided,
either of principal or interest, or in the event the entirety of the
indebtedness evidenced hereby is declared due, interest shall accrue at the
maximum rate allowed by law.

         All agreements between the Maker and the Payee, whether now existing
or hereafter arising and whether written or oral, are hereby expressly limited
so that in no event, whether by reason of acceleration of maturity hereof or
otherwise, shall the amount paid or agreed to be paid to the Payee for the use,
forbearance or detention of the money to be loaned hereunder or otherwise,
exceed the maximum amount permissible under applicable law.  If fulfillment of
any provision hereof or of any mortgage, loan agreement, or other document
evidencing or securing the indebtedness evidenced hereby, at the time
performance of such provision shall be due, shall involve transcending the
limit of validity prescribed by law, then, ipso facto, the obligation to be
fulfilled shall be reduced to the limit of such validity; and if the Payee
shall ever receive anything of value deemed interest under applicable law which
would exceed interest at the highest lawful rate, an amount equal to any
excessive interest shall be applied to the reduction of the principal amount
owing hereunder and not to the payment of interest, or if such excessive
interest exceeds the unpaid balance of principal hereof, such excess shall be
refunded to the Maker.  All sums paid or agreed to be paid to the Payee for
the use, forbearance, or detention of the indebtedness of the Maker to the
Payee shall, to the extent permitted by applicable law, be amortized, prorated,
allocated, and spread throughout the full term of such indebtedness until
payment in full so that the rate of interest on account of such indebtedness is
uniform throughout the term thereof.  The provisions of this paragraph shall
control all agreements between the Maker and the Payee.

         This note has been executed and delivered in and shall be construed in
accordance with and governed by the laws of the State of Texas and of the
United States of America, except that Tex. Rev. Civ. Stat. Ann. Art. 5069, Ch.
15, as amended (which regulates certain revolving credit loan accounts and
revolving tri-party accounts), shall not apply hereto.

         For purposes of any suit relating to this note, Maker hereof submits
itself to the jurisdiction of any court sitting in the State of Texas and
further agrees that venue in any suit arising out of this note or any venue
shall be fixed in Harris County, Texas.  Final judgment in any suit shall be
conclusive and may be enforced in any jurisdiction within or without the United
States of America, by suit on the judgment, a certified or exemplified copy of
which shall be conclusive evidence of such liability.

         THIS WRITTEN LOAN AGREEMENT REPRESENTS THE FINAL AGREEMENT BETWEEN THE
PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

         THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

                                        "MAKER"
