agent, and not with a view to the resale or distribution of any part thereof,
and the Company has no present intention of selling, granting any participation

Company to transfer shares to an affiliate (within the meaning of Rule 405
promulgated under the Securities Act) of the Company. The Company has no need
for liquidity related to the acquisition of the Investor Shares.

read or reviewed, and is familiar with, this Agreement and the other agreements
executed in connection with this Agreement and confirms that all documents.

requested by the Investor

                                       9

<PAGE>   10
have been made available to the Investor.

                  (c) The Company has had an opportunity to ask questions and
receive answers from the Investor regarding the terms and conditions of the
offering of the Investor Shares and about other information, documents and
records relative to Investor's business assets, financial condition, results of
operations and liabilities. The foregoing, however. does not limit or modify the
representations and warranties of the Investor in Section 4 of this Agreement or
the right of the Company to rely thereon.

acknowledges that it can bear the complete economic risk of its investment and
has such knowledge and experience in financial or business matters that it is
capable of evaluating the merits and risks of the investment in the Investor
Shares. The Company also represents it is an "accredited investor"' within the
meaning of Rule 501 (a) promulgated under the Securities Act.

                  (e) The purchase of the Investor Shares by the Company is
consistent with the general investment objectives of the Company. The Company
understands that the purchase of the Investor Shares involves a high degree of

enterprise, and there may be no established market for the Investor Shares.

purchasing are characterized as "restricted securities" under the federal
securities laws inasmuch as they are being acquired from the Investor in a
transaction not involving a public offering and that under such laws and
applicable regulations such securities may not be resold without registration
under the Securities Act and applicable state securities laws, except in certain
limited circumstances. In this connection, the Company represents that it is
familiar with Rule 144 under the Securities Act, as presently in effect, and
understands the resale limitations imposed thereby and by the Securities Act.
The Company agrees that in no event will it make a transfer or disposition of
any of the Investor Shares unless and until, if requested by the Investor, it
shall have furnished to the Investor (at the expense of the Company or
transferee) an opinion of counsel or other evidence, reasonably satisfactory to
the Investor, to the effect that such transfer may be made without restrictions
under the Securities Act. The Company understands that the Investor is under no
obligation to register any of the securities sold hereunder. The Company
understands that no public market now exists for the Investor Shares and that it
is uncertain whether a public market will ever exist for the Investor Shares.

                  (g) It is understood that the certificates evidencing the
Investor Shares shall bear the following legend, as well as any other legend as
may be required by applicable federal and state securities laws:

         "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE

                  (a) The Shares to be received by the Investor will be acquired
for investment for the Investor's own account, not as a nominee or agent, and
not with a view to the resale or distribution of any part thereof, and the
Investor has no present intention of selling, granting an,, participation in, or
otherwise distributing the same, but subject to the ability of the Investor to
transfer shares to an affiliate (within the meaning of Rule 405 promulgated
under the Securities Act) of the Investor.

                  (b) The Investor has had an opportunity to ask questions and
receive answers from the Company regarding the terms and conditions of the
offering of the Shares and about other information, documents and records
relative to the Company's business assets, financial condition, results of
operations and liabilities. The foregoing, however, does not limit or modify the
representations and warranties of the Company in Section 3 of this Agreement or
the right of the Investor to rely thereon.

Rule 501 (a) promulgated under the Securities Act.

                  (d) The Investor understands that the Shares it is purchasing

involving a public offering and that under such laws and applicable regulations
such securities may not be resold without registration under the Securities Act
and applicable state securities laws, except in certain limited circumstances.
In this connection, the Investor represents that it is familiar with Rule 144
under the Securities Act, as presently in effect, and understands the resale
limitations imposed thereby and by the Securities Act. The Investor agrees that
in no event will it make a transfer or disposition of any of the Shares unless
and until, if requested by the Company, it shall have furnished to the Company
(at the expense of the Investor or transferee) an opinion of counsel or other
evidence, reasonably satisfactory to the Company, to the effect that such
transfer may be made without restrictions under the Securities Act. The Investor
understands that the Company is under no obligation to register any of the
securities sold hereunder. The Investor understands that no public market now
exists for the Common Stock and that it is uncertain whether a public market
will ever exist for the Common Stock.

securities of the Company, (b) options to purchase or rights to subscribe for
Common Stock or other securities of the Company, (c) securities convertible into
or exchangeable for Common Stock or other securities of the Company, and (d)
options to purchase or rights to subscribe for such convertible or exchangeable
securities (collectively, the "Covered Securities"), the Company shall
automatically grant to the Investor sufficient Covered Securities described in
subsections (a) through (d) so as to maintain the Investor's then current
percentage ownership of the Company, with any convertible securities determined
on an as converted basis. The purchase price for such Covered Securities shall
be the par value of the securities issued (in the case of subsection (a)) or the
par value of the Common Stock into which such Covered Securities are convertible
(in the case of subsections (b) through (d)). Payment for such Covered
Securities shall be made by the Investor in cash upon ten (10) days prior notice
from the Company of such issuance. This additional issuance right shall not
apply to (A) shares of Common Stock, rights, options or warrants granted or
awarded by the Company, with the approval of its Board of Directors, including
the approval of the Board designee of the Investor, to employees, directors and
consultants of the Company as compensation for service to the Company in any
such capacities. if such rights, options or warrants are granted at an exercise
price or value not less than the fair market value of a share as of the date of
grant, up to and no more than an aggregate of 7,036 shares of Common Stock (as
adjusted to provide for any dividends, stock distributions, splits, combinations
or recapitalizations), (B) the issuance of Common Stock or securities
convertible into Common Stock in connection with any merger or acquisition
involving the Company, which merger or acquisition is properly authorized and
approved by the Board of Directors, including the approval of the Board designee
of the Investor, or (C) any Covered Securities where the additional issuance
rights have been waived in writing by the Investor.

         8.2 Right of First Refusal.

                  (a) In addition to the rights set forth in Section 8.1, and
until such time as the Company shall have consummated a registered public
offering, the Investor shall have the preemptive right to subscribe for the
issuance of any and all Covered Securities; provided, however, that the Investor
shall not have a preemptive right to subscribe for (A) shares of Common Stock,
rights, options or warrants granted or awarded by the Company, with the approval
of its Board of Directors, including the approval of the Board designee of the
Investor, to employees, directors and consultants of the Company as compensation
for service to the Company in any such capacities, if such rights, options or
warrants are granted at an exercise price or value not less than the fair market
value of

                                       19

<PAGE>   20
a share as of the date of grant, up to and no more than an aggregate of 7,036
shares of Common Stock (as adjusted to provide for any dividends, stock
distributions, splits, combinations or recapitalizations), (B) the issuance of
Common Stock or securities convertible into Common Stock in connection with any
merger or acquisition involving the Company, which merger or acquisition is
properly authorized and approved by the Board of Directors, including the
approval of the Board designee of the Investor, (C) any Covered Securities where
the preemptive rights have been waived in writing by the Investor, or (D) any
Covered Securities where the issuance of such Covered Securities would represent
less than a controlling interest in the Company for the holder of such
securities; provided, further, however, that such preemptive rights shall not
affect the Investor's rights under Section 8.1 with respect to any Covered
Securities issued to the Investor pursuant to such Section. For purposes of this
Agreement, an issuance of Covered Securities to a holder shall represent a
"controlling interest" in the Company if such issuance, when taken together with
all other Covered Securities directly or beneficially owned by such holder,
represents 30% or more of the combined voting power or ownership of the
outstanding capital stock of the Company, considered on an as converted basis
where applicable.

         (b) In the event the Company proposes to issue any Covered Securities
where such issuance is subject to the provisions of this Section, the Company
shall first make an offering of such securities in accordance with the following
provisions:

                  (i) The Company shall deliver a notice by certified mail (the
"Preemption Notice") to the Investor stating (A) its bona fide intention to
offer such securities, (B) the number of such securities to be offered, and (C)
the price and terms, if any, upon which it proposes to offer such securities.

                  (ii) Within twenty (20) calendar days after delivery of the
Preemption Notice, the Investor may elect to purchase or obtain, at the price
and on the terms specified in the Preemption Notice, up to all of such
securities; provided, however, that no such election to purchase securities
shall be binding upon the Investor unless and until such time as the Company has
obtained binding commitments to purchase all of the securities specified in the
Preemption Notice at the price and upon the terms specified in the Preemption
Notice.

                  (iii) The Company may, during the 60-day period following the
expiration of the period provided in subsection (ii), offer the unsubscribed
portion of the securities to any person or persons at a price not less than, and
upon terms no more favorable to the offeree than those specified in the
Preemption Notice. If the Company does not enter into an agreement for the sale
of the securities within such 60-day period, or if such agreement is not

Lextron Agreement.

9.       COMPANY PUT RIGHTS.

         9.1 Put. If (a) the Investor has not consummated an initial public
offering of the Investor Common Stock under the Securities Act by December 31,
2001, or (b) the Investor undergoes a "change of control," the Company shall
have the one (1) time right to sell ("Put") to the Investor all, but not less
than all, of the Investor Shares (the "Put Securities") for a period of thirty
(30) days following the occurrence of the trigger event described in clause (a)
or (b) of this Section 9.1. For purposes of this Section 9, a "change of
control" shall mean a merger, consolidation or other business combination
pursuant to which the shareholders of the Investor immediately prior to the
effective date of such transaction have beneficial ownership of less than fifty
percent (50%) of the total combined voting power for election of directors of
the surviving corporation immediately following such transaction and the
consideration for such merger, consolidation or other business combination does
not consist of cash and/or securities registered under the Securities Act.

         9.2 Exercise. In the event the Company wishes to exercise its right to
Put the Put Securities, the Company shall notify the Investor in writing of its
intention to exercise its Put right.

         9.3 Purchase. The purchase price (the "Put Price") of the Put
Securities shall be $500,000. The Investor shall purchase the Put Securities
within ninety (90) days from the date it receives notice of the Company's intent
to exercise the Put; provided, however, that if the Investor is unable to
purchase all of the Put Securities due to state law restrictions, the Put
Securities shall be repurchased from time to time to the maximum extent the
Investor is legally permitted to do so, and the Put obligation of the Investor
under this Section 9 will be a continuing obligation until the Investor's
repurchase of all the Put Securities.

         9.4 Closing. The Put closing (including any subsequent purchase closing
date if multiple purchases result from the application of Section 9.3), shall
occur at the Investor's principal office. At the Put closing, to the extent
applicable, the Company shall deliver the Put Securities being sold, duly
endorsed in blank, accompanied by such supporting documents as the Investor may
reasonably determine to be necessary to pass to the Investor good title to the
Put Securities, free and clear of all liens (other than restrictions under
applicable securities laws and/or any shareholders' agreements). In
consideration therefor, the Investor shall deliver to the Company payment, by
certified check, cashier's check, or wire transfer, of the aggregate Put Price.

         9.5 Transfer of Put Right. The Put right granted hereunder is not
assignable.

10.      REGISTRATION RIGHTS

         10.1 Optional Registrations.

                  (a) If, at any time or from time to time after the Investor
has closed an initial public offering of the Investor Common Stock, the Investor
decides to register any of the Investor Common Stock or securities convertible
or exchangeable for Investor Common Stock under the Securities Act on a form
suitable for an offering for cash, other than a registration solely to implement
an employee benefit plan or a transaction to which Rule 145 or any other similar
rule of the Securities and Exchange Commission (the "Commission") is applicable,
the Investor will promptly give written notice to the Company, and the Investor
will use reasonable efforts to effect the registration under the Securities Act

requests be included in such registration by a written notice delivered to the
Investor within fifteen (15) days after the notice given by the Investor.

                  (b) If the registration involves an underwritten public
offering, the Investor will not be required to register Registrable Securities
in excess of the amount that the principal underwriter reasonably and in good
faith recommends may be included in such offering (a "Cutback"). If such a
Cutback occurs, the number of shares that are entitled to be included in the
registration and underwriting shall first be allocated to the Investor for
securities being sold for its own account, shall next be allocated to holders
with registration rights existing prior to the date of this Agreement, and
thereafter shall be allocated among the other holders requesting inclusion in
the registration (including the Company) pro rata on the basis of the number of
shares each requesting holder requests be included bears to the total number of
shares of all requesting holders (other than the Investor) that have been
requested to be included in such registration.

                  (c) If the Investor elects to terminate any registration filed
under this Section, the Investor will have no obligation to register the
securities sought to be included by the Company in such registration. In
connection with a registration made by the Investor pursuant to this Section,
all expenses of the Investor for such registration and offering and the
reasonable fees and expenses of independent counsel for the Company will be

and commissions attributable to its Registrable Securities being registered and
transfer taxes on shares being sold by it).

"Registrable Securities" shall mean any shares of Investor Common Stock issued
pursuant to this Agreement, and any other securities issued as a dividend of
other distribution with respect to, or in exchange for or in replacement of, any
shares of Investor Common Stock issued pursuant to this Agreement, except for
shares of Investor Common Stock that have been sold or transferred pursuant to
an effective registration statement or pursuant to Rule 144 under the Securities

the Company, use reasonable efforts to register or qualify the Registrable
Securities covered by the registration statement under the securities or
"blue-sky" laws of such jurisdictions as are necessary to permit the sale of

itself to general service of process.

10.4     Indemnification.

                  (a) Subject to applicable law, the Investor will indemnify the

damages and liabilities, including legal and other expenses reasonably incurred,
arising out of any untrue or allegedly untrue statement of a material fact
contained in the registration statement, or any omission or alleged omission to
state a material fact required to be stated in the registration statement or
necessary to make the statements not misleading, or arising out of any violation

"blue-sky" laws or any applicable rule or regulation.

Investor, and each person controlling the Investor, against all claims, losses,
damages and liabilities, including legal and other expenses reasonably incurred.

contained in the registration statement, or required to be stated in the
registration statement o r necessary to make the statements contained therein
not misleading, to the extent, but only to the extent, that such untrue
statement or omission is contained in any information or affidavit furnished in
writing by the Company to the investor specifically for inclusion in such
registration statement. In no event shall the liability of the Company under
this paragraph be greater in amount than the dollar amount of the proceeds
received by the Company upon the sale of the Investor Common Stock pursuant to
the registration statement giving rise to such indemnification obligation.

         10.5 Rule 144 Requirements. If the Investor becomes subject to the
reporting requirements of the Securities Exchange Act of 1934, as amended, the
Investor will use reasonable efforts to file with the Commission such
information as the Commission may require and will use reasonable efforts to
make available Rule 144 under the Securities Act (or any successor exemptive
rule).

         10.6 Transfer of Registration Rights. The registration rights of the
Company under this Section 10 are not transferable and shall not be assigned by

                                                                      Exhibit A

                             SHAREHOLDERS' AGREEMENT


         THIS SHAREHOLDERS' AGREEMENT (the "Agreement") is made and entered into
as of August _, 1999, by and among TURNKEY COMPUTER SYSTEMS, INC., a Texas
corporation (the "'Company"), Stephen W. Myers, Debora P. Myers, Don Flynt,
Carey Coffman (the "Shareholders"), and EMERGE INTERACTIVE, Inc. (the
"Investor").

         WHEREAS, each of the Shareholders is now or hereafter may be the owner
of shares of capital stock of the Company or other securities that may be issued
in exchange for or in respect of shares of capital stock of the Company, whether
pursuant to any exercise, conversion, stock split, stock dividend, combination,
reclassification, reorganization or any other means (whether now or hereafter
acquired, the "Shares");

         WHEREAS, the Company and the Investor are parties to that certain
Common Stock Purchase Agreement, dated as of the date hereof (the "Purchase
Agreement");

         WHEREAS, the obligations of the Company and Investor under the Purchase
Agreement are conditioned, among other things, upon the execution and delivery
of this Agreement by the Company, Shareholders and Investor, and

         WHEREAS, each of the parties to this Agreement have agreed on the terms
and conditions set forth in this Agreement.

         NOW, THEREFORE, in consideration of the foregoing, the agreements set
forth below, and the parties' desire to provide for the continuity of ownership
of the Company to further the interests of the Company and its present and
future shareholders, the parties agree as follows:

1.       Investor Right of First Refusal.

         (a) Prior to any sale, transfer, pledge or other disposition
(collectively, a "Transfer") of any Shares owned by any Shareholder, such
Shareholder shall offer to the Investor the right, for a period of twenty-five
(25) business days from the date the Investor receives the written notice
described in subsection (b), below, the 25th such day being the "Effective
Date," to purchase all of such Shares for cash at an amount equal to the price
or other consideration for which such Shares are to be Transferred.
Notwithstanding the foregoing, a Shareholder may Transfer Shares: (i) pursuant
to a transfer or disposition by will or the laws of descent and distribution due
to the death of such Shareholder; (ii) pursuant to a sale between Shareholders
of less than a "controlling interest" (as defined below); or (iii) pursuant to a
sale representing less than a controlling interest in the Company; provided, in
each case, that the transferee under such provision agrees in writing with the
Company and the Investor to be bound by and subject to the terms of this
Agreement (such transferees being collectively referred to as the "Permitted

<PAGE>   30
Transferees"). For purposes of this Agreement, a sale of Shares shall represent
a "controlling interest" in the Company if the Shares subject to such Transfer,
when taken together with all other Shares directly or beneficially owned by the
transferee of such Transfer, represents 30% or more of the combined voting power
or ownership of the outstanding capital stock of the Company, considered on an
as-converted basis where applicable.

                  (b) With respect to each Transfer of Shares, the Shareholder
proposing such Transfer (the "Transferring Shareholder") shall provide written
notice to the Investor. Such written notice shall describe: (i) the Shares
proposed to be Transferred; (ii) whether the proposed transferee constitutes a
Permitted Transferee; and (iii) the number, price, payment, closing and other
relevant terms of the proposed Transfer. The Investor may indicate its interest
in purchasing all or any, lesser number of the Shares offered by the
Transferring Shareholder to a transferee that is not a Permitted Transferee by
providing written notice thereof to the Transferring Shareholder prior to the
expiration of the twenty-five (25) day period. In such event, the Transferring
Shareholder shall promptly Transfer to the Investor, upon the terms specified in
the notice from the Transferring Shareholder to the Investor, the number of
Shares specified in the notice from the Investor to the Transferring
Shareholder.

                  (c) In the event that the offer set forth in the notice
delivered by the Transferring Shareholder to the Investor is thereafter
modified, or in the event such proposed offer does not close within thirty (30)
days after the Effective Date, then the Transferring Shareholder must once again
offer such Shares to the Investor pursuant to the terms of this Agreement.

                  (d) The provisions of this Section shall be, where applicable,
subordinate to the existing rights of first refusal or collateral rights held by
Lextron, Inc. pursuant to that certain Agreement dated as of February 18, 1997
by and among the Company, Lynn R. Camp, Barbara A. Camp, Stephen W. Myers,
Debora P. Myers and Lextron, Inc.

         2. Company Right of First Refusal.

                  (a) Prior to any Transfer of any Shares owned by the Investor,
the Investor shall offer to the Company the right, for a period of twenty-five
(25) business days from the date the Company receives the written notice
described in subsection (b), below, to purchase all of such Shares for cash at
an amount equal to the price or other consideration for which such Shares are to
be Transferred. Notwithstanding the foregoing, the Company may Transfer Shares
to any of its affiliates, as defined in the Securities Act of 1933, as amended
(an "Investor Permitted Transferee").

                  (b) With respect to each Transfer of Shares by the Investor,
the Investor shall provide written notice to the Company. Such written notice
shall describe: (i) the Shares proposed to be Transferred; (ii) whether the
proposed transferee constitutes an Investor Permitted Transferee; and (iii) the
number, price, payment, closing and other relevant terms of the proposed
Transfer. The Company may indicate its interest in

                                       2

<PAGE>   31
purchasing all or any lesser number of the Shares offered by the Investor to a
transferee that is not an Investor Permitted Transferee by providing written
notice thereof to the Investor prior to the expiration of the twenty-five (25)
day period. In such event, the Investor shall promptly Transfer to the Company,
upon the terms specified in the notice from the Investor to the Company, the
number of Shares specified in the notice from the Company to the Investor.

                  (c) In the event that the offer set forth in the notice
delivered by the Investor to the Company is thereafter modified, or in the event
such proposed offer does not close within thirty (30) days after the Effective
Date, then the Investor must once again offer such Shares to the Company
pursuant to the terms of this Agreement.

                  (d) The rights of the Investor under Sections I and ') of this
Agreement, and Sections 7.7, 7.8, 8.1 and 8.2 of the Purchase Agreement, are
particular to the Investor and any Investor Permitted Transferee. In addition to
the termination of such rights under any other provision of this Agreement or
the Purchase Agreement, such rights shall terminate upon any Transfer occurring
after the final Additional Closing Date where upon the completion of such
Transfer the Investor and all Investor Permitted Transferees own in an aggregate
less than 50% of the Shares owned as of such final Additional Closing Date.

         3. Investor Voting Rights. The Investor shall have the right to elect
one person to, and the right to remove such person from, the Board of Directors.
The Shareholders agree to vote all of their Shares for the Director selected by
the Investor pursuant to this Agreement at any annual or special meeting or
pursuant to any written consent, conducted or solicited for the purpose of
electing directors. The voting agreement contained in this Section is coupled
with an interest and the obligation assumed by the Shareholders to vote their
Shares as set forth above shall be deemed to be a right coupled with an interest
in favor of the Investor. In the event of any resignation (or removal by the
Investor) of the Director elected by the Investor, the Shareholders shall take
all actions necessary and appropriate to cause such vacancy to be filled in
accordance with the provisions hereof. The provisions of this Section shall be
subject to the provisions of Section 11.4 of the Purchase Agreement (insofar as
those provisions relate to Section 7.7 of the Purchase Agreement).

         4. Term. This Agreement shall terminate upon the earlier of the written
agreement of the parties or at such time as the Investor ceases to be a holder
of Shares of the Company.

         5. Specific Enforcement. The parties agree that as to the matters
expressed in this Agreement, they will be irreparably damaged if this Agreement
is not specifically enforced. Upon a breach or threatened breach of the terms,
covenants and/or conditions of this Agreement by the Company and/or the
Shareholders, the Investor shall, in addition to all other remedies, be entitled
to a temporary or permanent injunction, without showing any actual damage,
and/or a decree for specific performance, in accordance with the provisions
hereof.

Transferee and setting forth the terms of the proposed transaction, which shall
be limited to transactions involving cash against delivery of the Stock. The

20-day acceptance period specified in Section 2.2(b), Transfer all, but not less
than all, of the remaining Stock to such third party at the price and on the
terms set forth in its Offer Notice, subject to Section 2.3. If such Stock is
not so sold within such 30 day period, the Selling Stockholder shall not
Transfer such Stock without again giving an Offer Notice under this Section 2.2.

         SECTION 2.3 JOINDER TO AGREEMENT. Any Transfer that is otherwise
permissible under or in accordance with Section 2.1 or Section 2.2, shall not be

extent possible in accordance with their terms. This Agreement shall be
construed and interpreted in accordance with the laws of the State of Delaware,
without regard to its provisions concerning conflict of laws.

         SECTION 3.10 INJUNCTIVE RELIEF. It is acknowledged that it will be
impossible to measure the damages that would be suffered by a party if another
party fails to comply with the provisions of this Agreement and that in the
event of any such failure, each non-breaching party will not have an adequate
remedy at law. Therefore, any party shall be entitled to obtain specific
performance of another party's obligations hereunder and to obtain injunctive
relief. No party shall argue, as a defense to any proceeding for such specific
performance or injunctive relief, that another party has an adequate remedy at
law.

         SECTION 3.11 COUNTERPARTS. This Agreement may be executed in one or
more counterparts each of which shall be deemed to be an original, but all of
which taken together shall constitute one and the same instrument. Each such
copy shall be deemed an original, and it shall not be necessary in making proof
of this Agreement to produce or account for more than one such counterpart.
