                              EMPLOYMENT AGREEMENT

        THIS EMPLOYMENT AGREEMENT (the "Agreement") is made and entered into as
of the 16th day of September, 1999, by and among G-Link Corporation, a Tennessee
corporation (the "Company"), and Richardson M. Roberts (the "Executive").

        WHEREAS, the Company desires to provide Executive with compensation and
other benefits on the terms and conditions set forth in this Agreement in order
to induce Executive to serve as the Chief Executive Officer and President of the
Company; and

        WHEREAS, Executive is willing to accept such employment and perform
services for the Company, on the terms and conditions hereinafter set forth.

        NOW, THEREFORE, in consideration of the premises hereof and of the
mutual promises and agreements contained herein, the parties hereto, intending
to be legally bound, hereby agree as follows:

        1.     Employment and Term of Employment. The Company hereby agrees to
employ the Executive as its Chief Executive Officer and President, and the
Executive hereby agrees to serve the Company, on the terms and conditions set
forth herein, for the period commencing as of the date set forth above and
continuing for three years thereafter (the "Initial Term"), unless sooner
terminated as hereinafter set forth. This Agreement will be renewed
automatically on each anniversary of the date hereof for additional one year
terms (the "Renewal Term(s)" and, together with the Initial Term, the
"Employment Period"), unless the Company or the Executive gives written notice
to the other at least 30 days prior to any such anniversary of its decision not
to renew this Agreement. Executive shall perform the duties normally performed
by a Chief Executive Officer and President. During the Employment Period,
Executive shall serve as a director of the Company; provided, however, that upon
termination of employment for any reason, Executive shall immediately resign as
a director.

        2.     Extent of Services. The Executive shall devote substantially all
his working time and efforts to the business and affairs of the Company, shall
use his best efforts to advance the best interests of the Company, and shall not
engage in outside business activities that interfere with the performance of his
duties hereunder. Nothing in this Agreement shall preclude executive from
serving on Boards of Directors or making investments in other companies and
participating in charitable or community activities that do not substantially
interfere with his duties and responsibilities hereunder or conflict with the
interest of the Company.

        3.     Compensation.

               a. Base Salary. The Executive shall receive a base salary at the
rate of $225,000 per year ("Base Salary") payable in equal periodic payments,
which payments shall be made no less frequently than monthly during the period
of the Executive's employment hereunder.

               b. Annual Bonus. In addition to Base Salary, the Executive will
be entitled to receive, as additional compensation, an annual bonus at the
discretion of the Compensation Committee of the Board of Directors. The annual
bonus to which the Executive is entitled shall be based upon the extent to which
the Executive meets the performance criteria established for each year by the
Compensation Committee in its sole discretion, but to be established prior to or
within the first 90 days of each performance period. These performance criteria
are as initially set forth on Exhibit A hereto and may be amended on an annual
basis by the Compensation Committee.

               c. Expenses. During the term of his employment hereunder, the
Executive shall be entitled to be reimbursed (in accordance with the policies
and procedures established by the Board of Directors of the Company) for all
reasonable expenses incurred by him in performing services hereunder, provided
that the Executive properly accounts therefor in accordance with the Company's
policy. In addition, during the Employment Period, the Executive shall (i) be
reimbursed for monthly dues for membership in one country club of his choosing
and (ii) be entitled to a reasonable monthly vehicle allowance.

               d. Participation in Benefit Plans. Executive shall be entitled to
participate in or receive benefits under the Company's executive benefit plans
and arrangements, including life and disability insurance, in effect on the date
hereof that are generally made available to all senior executives of the Company
on terms at least as favorable as those offered to other senior executives of
the Company. In addition, the Company may elect to obtain key-man life insurance
coverage on the Executive, and the Executive agrees to submit to any medical
examination that is reasonably required for underwriting purposes. At a minimum,
the Company shall obtain for the Executive (i) disability coverage to replace
Executive's Base Salary for the entire period of his disability and (ii) life
insurance of $500,000.

        4.     Termination.

               a. Disability. If, as a result of the Executive's incapacity due
to physical or mental illness, the Executive shall have been absent from his
duties hereunder on a full time basis for 90 consecutive business days, the
Company may terminate its obligations hereunder, except for those obligations
set forth in Section 5(b) hereof. The determination of whether the Executive is
disabled due to physical or mental illness shall be made by a licensed physician
satisfactory to the Executive and to the Company.

               b. Termination Upon Death. If the Executive should die during the
term of this Agreement, the Company's obligations under this Agreement shall

Executive's employment shall be terminated.

               c. Termination by the Company. The Company may terminate the

adverse effect upon the Company, and that constitutes on the part of the

inquiry.

               d. Termination by Executive. Executive may terminate this
Agreement on two weeks' notice, and the Company shall have no obligations to

        Benefits, all of which shall be paid to Executive within ten days
        following the date of termination.

                       d. Notice of Termination. Any termination of Executive's
        employment by the Company or by Executive pursuant to this Section 6

        facts and circumstances claimed to provide a basis for termination of
        Executive's employment and shall state the date of termination.

                       e. Special Rule Applicable to Termination Within Six
        Months Prior to a Change of Control. Upon any termination of Executive's

                       (iv)   The "Code" shall mean the Internal Revenue Code of
                              1986, as amended.

                       (v)    An "Excess Parachute Payment" shall mean any
                              payment, benefit or any portion thereof, whether
                              under this Agreement or as a result of Executive's
                              participation in any of the Company's stock option
                              or employee incentive plans, which would be an
                              "excess parachute payment" within the meaning of
                              Section 280G(b) of the Code, and which would
                              result in the imposition of an excise tax on the
                              Executive under Section 4999 of the Code.

               b. Payment of Additional Amount. Notwithstanding anything to the
contrary contained in this Agreement, in any plan of the Company, or in any
other agreement or understanding, following a "change in control" (as defined in
Section 280G of the Code) will pay to the Executive, at the times herein
specified, an amount (the "Additional Amount") equal to the excise tax under
Section 4999 of the Code, if any, incurred or to be incurred by the Executive by
reason of the payments under this Agreement, acceleration of vesting of stock
options, stock appreciation rights or restricted stock granted under the
Company's various stock option, stock appreciation or other employee incentive
plans, or payments under any other plan, agreement or understanding between the
Executive and the Company, constituting Excess Parachute Payments, plus all
excise taxes and federal, state and local income taxes incurred or to be
incurred by the Executive with respect to receipt of the Additional Amount.
Attached hereto as Exhibit B is an example illustrating the computation of the
Additional Amount.

               c. Opinion of Tax Firm. All determinations required to be made
regarding the Additional Amount, including whether payment of any Additional
Amount is required and the amount of any Additional Amount, shall be made by the
Tax Firm, which shall provide detailed

                                       8
<PAGE>   9

support calculations to the Company and the Executive on or before the last day
of the Change of Control Year. In computing taxes, the Tax Firm shall use the
highest marginal federal, state and local income tax rates applicable to single
taxpayers for the year in which the Additional Amount is to be paid (unless,
within 30 days after the occurrence of the change in control the Executive
specifies in writing to the Company his marginal tax rate) and shall assume the
full deductibility of state and local income taxes for purposes of computing
federal income tax liability.

               d. Time of Payment of Additional Amount. The portion of the
Additional Amount based on the excise tax as determined by the Tax Firm to be
due for the Change of Control Year shall be paid to the Executive no later than
March 1 immediately following the end of the Change of Control Year. The portion
of the Additional Amount based on the excise tax as determined by the Tax Firm
to be Due for each calendar year following the Change of Control Year shall be
paid to the Executive on or before March 1 immediately following the end of each
such calendar year. If the Company determines that the excise tax for any year
will be different from the amount originally calculated in the report of the Tax
Firm delivered at the end of the Change of Control Year, then the Company shall
provide to the Executive detailed support calculations by the Tax Firm
specifying the basis for the change in the Additional Amount.

        8.     Binding Agreement. This Agreement and all obligations of the
Company hereunder shall be binding upon the successors and assigns of the
Company. This Agreement and all rights of the Executive hereunder shall inure to
the benefit of and be enforceable by the Executive's personal or legal
representatives, executors, administrators, successors, heirs, distributees,
devisees, and legatees. The Company may assign its rights and delegate its
duties under this Agreement at any time, without the consent of Executive, to
one or more affiliates of the Company.

        9.     Non-Competition; Non-Solicitation. For a period of three years
following Executive's termination of employment, the Executive will not,
directly or indirectly, within the territorial limits of the United States of
America, without the prior written consent of the Company (i) directly or
indirectly, either as principal, manager, agent, consultant, officer,
shareholder, partner, investor, lender or employee or in any other capacity,
carry on, be engaged in or have any financial interest in, any business in
competition with the business of providing transaction outsourcing services to
government entities in which the Company participated on the date of termination
of employment; or (ii) recruit or hire or solicit for business any person who,
during the 12-month period preceding the date of recruitment or hiring or
solicitation, was an executive, customer, or client of the Company or any of its
subsidiaries or affiliates. Nothing herein shall prohibit the Executive from
acquiring a passive investment in a publicly-held company of up to 1% of the
outstanding common shares thereof.

        10.    Unauthorized Disclosure.

               a. During the period of his employment hereunder, the Executive
shall not, without the prior written consent of the Company, disclose to any
person, other than a person to whom disclosure is necessary or appropriate in
connection with the performance by the Executive of his duties as an executive
of the Company, or any of its subsidiaries or affiliates (including any

                                       9

<PAGE>   10

attorney, accountant, or financial advisor to Executive), any confidential
information obtained by him while in the employ of the Company, or its
subsidiaries or affiliates, with respect to any of the Company's (or any
subsidiary's) products, services, improvements, designs, methodologies,
processes, customers, methods of marketing or distribution, systems, procedures,
plans, proposals, or policies, the disclosure of which he knows, or should have
reason to know, could be damaging to the Company or its subsidiaries or
affiliates. Following the termination of employment hereunder, the Executive
shall not disclose any confidential information of the type described above
except as may be required by order of court in connection with any judicial or
administrative proceeding or inquiry; provided, however, nothing contained in
this Section 10 shall apply to any knowledge or information that (1) is
generally available to the public or becomes generally available to the public
other than as a result of a disclosure in violation hereof by Executive, (2)
prior to its disclosure, was available to Executive prior to his association
with the Company or (3) becomes available to Executive from a source other than
the Company or any of its Representatives, provided that such source is not, to
Executive's knowledge, bound by a confidentiality agreement with respect to such
information. For purposes of this Agreement, the term "Representatives" shall
mean the Company's directors, officers, employees, attorneys, accountants and
others engaged by the Company or intended to be engaged by the Company to advise
it.

               b. The foregoing provision of this Section 10 shall be binding
upon the Executive's heirs, successors, and legal representatives.

        11.    Injunction. The Executive acknowledges and agrees that, in the
event of a breach of Section 9 or Section 10 hereof by the Executive, the
Company would be irreparably harmed and that monetary damages would be an
inadequate remedy in favor of the Company. Accordingly, the parties agree that
in the event of such a breach, the Company shall be entitled to injunctive
relief against the Executive, in addition to any other remedies or damages
available to it.

        12.    Indemnification.

               a. In the event that an excise tax is ever assessed by the
        Internal Revenue Service against the Executive (or if the Company and
        the Executive mutually agree that an excise tax is payable) by reason of
        any payment under this Agreement, acceleration of vesting of stock
        options, stock appreciation rights or restricted stock granted under the
        Company's stock option, stock appreciation or other employee incentive
        plans, or payments under any other plan, agreement or understanding
        between the Executive and the Company, constituting Excess Parachute
        Payments, and if such excise tax was not included in the determination
        by the Tax Firm of the Additional Amount that has been actually paid to
        the Executive, the Company agrees to indemnify the Executive by paying
        to the Executive the amount of such excise tax, together with any
        interest and penalties, including reasonable legal and accounting fees
        and other out-of-pocket expenses incurred by the Executive, attributable
        to the failure to pay such excise tax by the date it was originally due,
        plus all federal, state and local income taxes incurred with respect to
        payment of the excise tax calculated in a manner analogous to Exhibit B.
        Upon Executive's receipt from the Internal Revenue Service ("IRS") of
        any deficiency notice, notice of assessment or any other written

                                       10
<PAGE>   11

        communication relating to the excise tax on an Excess Parachute Payment,
        Executive shall give notice thereof to the Company within ten business
        days of Executive's actual receipt thereof. In the event of any dispute
        concerning the potential excise tax (including any administrative
        proceedings within the IRS or court proceedings), the Company, as the
        indemnifying party. shall be entitled to assume the defense of such a
        dispute or proceeding, no compromise or settlement of such claim may be
        effected without the Company's and Executive's mutual consent (which
        consents shall not be unreasonably withheld) and the Company shall have
        no liability with respect to any compromise or settlement of such claims
        effected without its consent, unless such consent has been unreasonably
        withheld. In addition, in the event the Company assumes defense of any
        proceeding, the Executive shall not be entitled to indemnification for
        outside legal fees and expenses independently incurred by Executive
        after the date on which the Company assumed such defense. This
        indemnification obligation shall survive the termination of the
        Agreement and shall apply to all such excise taxes on Excess Parachute
        Payments, whether due before or after termination of employment.

               b. If the excise tax for any year which is actually imposed on
        the Executive is finally determined to be less than the amount taken
        into accounting the calculation of the Additional Amount that was paid
        to the Executive pursuant to Section 7, then the Executive shall repay
        to the Company, at the time that the amount of such reduction in excise
        tax is finally determined, the portion of the Additional Amount
        attributable to such reduction (including the portion of the Additional
        Amount attributable to the excise tax and federal and state income taxes
        imposed on the Additional Amount being repaid by the Executive, to the
        extent that such repayment results in a reduction in such excise tax,
        federal or state income tax).

        13.    Notice. For the purposes of this Agreement, notices and all other
communications provided for in the Agreement shall be in writing and shall be
deemed to have been duly given when delivered or, if mailed by United States
registered mail, return receipt requested, postage prepaid, three days following
the date of mailing addressed as follows:

-------------------

       * The formula used to compute the Additional Amount is to divide the
initial excise tax amount (line 2) by a percentage equal to 100% less the sum of
the excise tax percentage plus the state income tax percentage, plus the federal
tax percentage less a percentage determined by multiplying the federal tax
percentage times the state tax percentage. Thus, in the example above, the
following percentages should be subtracted from 100%.

The resulting percentage of 100% - 59.60% = 40.40% is divided into $10,000.
$10,000/.4040 = $24,752.

shares of Common Stock.

        (b) The shares of Common Stock issuable upon exercise of this Warrant
are hereinafter referred to as the "Shares." This Warrant shall be exercisable
at any time and from time to time from the date hereof until ten (10) years from

thereafter, execute and deliver to the Holder of this Warrant a certificate or
certificates for the total number of whole Shares for which this Warrant is
being exercised in such names and denominations as are requested by such Holder.
If this Warrant shall be exercised with respect to less than all of the Shares,
the Holder shall be entitled to receive a new Warrant covering the number of
Shares in respect of which this Warrant shall not have been exercised, which new
Warrant shall in all other respects be identical to this Warrant.

        Section 4. Covenants and Conditions. The above provision is subject to
the following:

        (a) Neither this Warrant nor the Shares have been registered under the
Securities Act or any state securities laws ("Blue Sky Laws"). The Holder
acknowledges and agrees that this Warrant has been acquired for investment
purposes and not with a view to distribution or resale in violation of the
registration provisions of the Securities Act. This Warrant may not be pledged,
hypothecated, sold, made subject to a security interest, or otherwise
transferred without (i) an effective registration statement for such Warrant
under the Securities Act and such applicable Blue Sky Laws or (ii) an opinion of
counsel, which opinion and counsel shall be reasonably satisfactory to the
Company and its counsel, that registration is not required under the Securities
Act or under any applicable Blue Sky Laws; and transfer of Shares issued upon
the exercise of this Warrant shall be restricted in the same manner and to the
same extent as the Warrant, and the certificates representing such Shares shall
bear substantially the following legend:

        THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR ANY
APPLICABLE STATE SECURITIES LAW AND MAY NOT BE TRANSFERRED UNTIL (I) A
REGISTRATION STATEMENT UNDER THE ACT OR SUCH APPLICABLE STATE SECURITIES LAWS
SHALL HAVE BECOME EFFECTIVE WITH REGARD THERETO OR (II) IN THE OPINION OF
COUNSEL ACCEPTABLE TO THE COMPANY, REGISTRATION UNDER THE ACT OR SUCH APPLICABLE
STATE SECURITIES LAWS IS NOT REQUIRED IN CONNECTION WITH SUCH PROPOSED TRANSFER.

                                       2

<PAGE>   3

        THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO TRANSFER AND
OTHER RESTRICTIONS AND CONDITIONS ALL AS SET FORTH IN THE SHAREHOLDERS AGREEMENT
DATED SEPTEMBER 16, 1999.

The Holder hereof and the Company agree to execute such other documents and
instruments as counsel for the Company reasonably deems necessary to effect the
compliance of the issuance of this Warrant and any shares of Common Stock issued
upon exercise hereof with applicable federal and state securities laws.

        (b) Holder hereby agrees to be bound by the provisions of the
Shareholders Agreement dated as of September 16, 1999 among the Company and the
shareholders of the Company signatory thereto. Upon the Company's request,
Holder agrees to execute a counterpart to the Shareholders Agreement to evidence
the foregoing.

        (c) The Company covenants and agrees that all Shares that may be issued
upon exercise of this Warrant will, upon issuance and payment therefor, be
legally and validly issued and outstanding, fully paid and nonassessable, free
from all taxes, liens, charges, and preemptive rights, if any, with respect
thereto or to the issuance thereof. The Company shall at all times reserve and
keep available for issuance upon the exercise of this Warrant such number of
authorized but unissued shares of Common Stock as will be sufficient to permit
the exercise in full of this Warrant.

        Section 5. Adjustment of Exercise Price and Number of Shares Issuable.
The Exercise Price and the number of Shares (or other securities or property)
issuable upon exercise of this Warrant shall be subject to adjustment from time
to time upon the occurrence of any of the events enumerated in this Section 5.

        (a) Common Stock Reorganization. If the Company shall (i) subdivide or
consolidate its outstanding shares of Common Stock (or any class thereof) into a
greater or smaller number of shares; (ii) pay a dividend or make a distribution
on its Common Stock (or any class thereof) in shares of its capital stock; or
(iii) issue by reclassification of its Common Stock (or any class thereof) any
shares of its capital stock (any such event described in clauses (i), (ii), or
(iii) being called a "Common Stock Reorganization"), then the Exercise Price and
the type of securities for which this Warrant is exercisable shall be adjusted
immediately such that the Holder thereafter shall be entitled to receive upon
exercise of this Warrant the aggregate number and type of securities that it
would have received if this Warrant had been exercised immediately prior to such
Common Stock Reorganization.

        (b) Capital Reorganizations. If there shall be any consolidation,
merger, or amalgamation of the Company with another person or entity or any
acquisition of capital stock of the Company by means of a share exchange, other
than a consolidation, merger, or share exchange in which the Company is the
continuing corporation, or any sale or conveyance of the property of the Company
as an entirety or substantially as an entirety, or any reorganization or
recapitalization of the Company (any such event being called a "Capital
Reorganization"), then the Holder of this

                                       3
<PAGE>   4

Warrant shall no longer have the right to purchase Common Stock, but shall have
instead the right to purchase, upon exercise of this Warrant, the kind and
amount of shares of stock and other securities and property (including cash)
that the Holder would have owned or have been entitled to receive pursuant to
such Capital Reorganization if this Warrant had been exercised immediately prior
to the effective date of such Capital Reorganization. As a condition to
effecting any Capital Reorganization, the Company or the successor or surviving
corporation, as the case may be, shall assume by a supplemental agreement,
satisfactory in form, scope, and substance to the Holder (which shall be mailed
or delivered to the Holder of this Warrant at the last address of such Holder
appearing on the books of the Company) the obligation to deliver to such Holder
such shares of stock, securities, cash, or property as, in accordance with the
foregoing provisions, such Holder may be entitled to purchase after giving
effect to the Capital Reorganization, and all other obligations of the Company
set forth in this Warrant.

        (c) Adjustment Rules. Any adjustments pursuant to this Section 5 shall
be made successively whenever an event referred to herein shall occur. No
adjustment shall be made pursuant to this Section 5 in respect of the issuance
from time to time of shares of Common Stock upon the exercise of this Warrant or
upon the exercise or conversion of any other stock or other securities
convertible into or exchangeable for Common Stock ("Convertible Securities") or
any rights to subscribe for or to purchase, or any warrants or options for the
purchase of, Common Stock or Convertible Securities.

        (d) Notice of Adjustment. Not less than 10 days prior to the record date
or effective date, as the case may be, of any action that requires or might
require an adjustment or readjustment pursuant to this Section 5, the Company
shall give notice to the Holder of such event, describing such event in
reasonable detail and specifying the record date or effective date, as the case
may be, and, if determinable, the required adjustment and the computation
thereof. If the required adjustment is not determinable at the time of such
notice, the Company shall give notice to the Holder of such adjustment and
computation promptly after such adjustment becomes determinable.

        Section 6. Warrant Transfer Provisions. THIS WARRANT MAY NOT BE SOLD,
TRANSFERRED, ASSIGNED, HYPOTHECATED OR OTHERWISE DISPOSED OF UNLESS PREVIOUSLY
CONSENTED TO IN WRITING BY THE COMPANY, AND NO SALE, TRANSFER, ASSIGNMENT,
HYPOTHECATION OR OTHER DISPOSITION OF THIS WARRANT PRIOR TO SUCH DATE SHALL BE
VALID OR EFFECTIVE UNLESS PREVIOUSLY CONSENTED TO IN WRITING BY THE COMPANY. Any
transfer of this Warrant, if previously consented to by the Company, is
registrable at the office or agency of the Company referred to in Section 8
below by the Holder in person or by his duly authorized attorney, upon surrender
of this Warrant properly endorsed.

        Section 7. No Rights or Liabilities as a Shareholder. This Warrant shall
not entitle the Holder to any voting rights or other rights as a shareholder of
the Company. No provision of this Warrant, in the absence of affirmative action
by the Holder to purchase Shares, and no mere enumeration herein of the rights
or privileges of the Holder, shall give rise to any liability of Holder

                                       4
<PAGE>   5

for the Exercise Price or as a shareholder of the Company, whether such
liability is asserted by the Company or by creditors of the Company.

        Section 8. Notices. All notices, requests and other communications
required or permitted to be given or delivered hereunder to the holder of this
Warrant shall be in writing, and shall be personally delivered, or shall be sent
by certified or registered mail, postage prepaid and addressed, to Holder at the
address shown for Holder on the books of the Company, or at such other address
as shall have been furnished to the Company by notice from Holder. All notices,
requests and other communications required or permitted to be given or delivered
hereunder to the Company shall be in writing and shall be personally delivered,
or shall be sent by certified or registered mail, postage prepaid and addressed
to the office of the Company at 3841 Green Hills Village Drive, Suite 400,
Nashville, Tennessee 37215, or at such other address as shall have been
furnished to the Holder by notice from the Company. All notices, requests and
other communications shall be deemed to have been given either at the time of
the delivery thereof to the person entitled to receive such notice at the
address of such person for purposes of this Section 8, or, if mailed, at the
completion of the third full day following the date of such mailing thereof to
such address, as the case may be.

        Section 9. Fractional Shares. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Warrant, but the
Company shall pay the Holder an amount equal to the fair market value of such
fractional share of Common Stock in lieu of each fraction of a share otherwise
called for upon any exercise of this Warrant.

        Section 10. Applicable Law. The Warrant is issued under and shall for
all purposes be governed by and construed in accordance with the laws of the
State of Tennessee applicable to contracts made and to be performed wholly
within such state without regard to its conflict of laws rules.

        Section 11. Miscellaneous.

               (a) Amendments. This Warrant and any provision hereof may not be
changed, waived, discharged or terminated orally, but only by an instrument in
writing signed by the party (or any predecessor in interest thereof) against
which enforcement of the same is sought.

               (b) Descriptive Headings. The descriptive headings of the several
Paragraphs of this Warrant are inserted for purposes of reference only and shall
not affect the meaning or construction of any of the provisions hereof.

               (c) Successors and Assigns. This Warrant shall be binding upon
any entity succeeding to the Company by merger, consolidation or acquisition of
all or substantially all of the Company's assets.
