of his ability and experience faithfully perform all of the duties that may be
required of him pursuant to the terms of this Agreement.

     D.  Neither the foregoing nor any other provision of this Agreement is
intended or shall be construed as preventing Executive from devoting his time
and effort to charitable and community activities substantially to the same
extent as he has devoted time and effort prior to the effective date of this
Agreement provided that such involvement with charitable and community
activities does not materially interfere with the performance of his duties
under this Agreement.

     4.  Early Termination.
         ----------------- 

         A.  For Cause.
             --------- 

                (i) Notwithstanding the foregoing, Company may terminate the
employment of Executive "for cause" (as hereinafter defined) at any time upon
written notice effective immediately. The term "for cause" shall mean (1) the
continued failure by Executive substantially to perform his duties with Company
in a reasonably professional manner other than due to a Total and Permanent
Disability or death for a period of thirty (30) days after a written demand for
substantial performance is delivered to Executive by the Board of Directors or
President of Company, which demand identifies the manner in which the Board of
Directors or President believes Executive has not substantially performed his
duties; (2) the unauthorized dissemination of Confidential Information (as
defined below) of Company or any of its subsidiaries; (3) the commission of a
felony or any other crime involving moral turpitude or the pleading of nolo
contendere to any such act; (4) the commission of any act of dishonesty when
such act is intended to result or results, directly or indirectly, in gain or
personal enrichment of Executive or any related person or affiliate of Executive
or is intended to cause harm or damage to Company or any of its subsidiaries;
(5) the illegal use of controlled substances; (6) the use of alcohol so as to
have a material adverse effect on the performance of his duties; (7) the
misappropriation or embezzlement of assets of Company or any of its
subsidiaries; (8) the making of material disparaging remarks regarding Company
or the products or services of any such person to suppliers and/or customers of
Company or any of its subsidiaries or (9) the breach of any other material term
or provision of this Agreement to be performed by Executive which has not been
cured within thirty (30) days of receipt of written notice of such breach.

                (ii) Upon termination of Executive's employment for cause,
Company shall have no further obligation to pay any compensation to Executive
for periods after the effective date of the termination for cause, except for
Base Salary which accrued as of the termination date. In addition, the right to
exercise any vested stock option shall terminate on the thirtieth (30th) day
following the effective date of the termination of employment for cause.

     B.  Termination Upon Death or Total and Permanent Disability.
         -------------------------------------------------------- 

                (i) The employment of Executive shall terminate upon his death
or, ten (10) business days after written notice by Company of termination, upon
or during the continuance of the Total and Permanent Disability (as hereinafter
defined) of Executive.

                (ii) Upon termination upon death or upon or during Executive's
Total and Permanent Disability, Company shall have no further obligation to pay
any compensation for periods after the effective date of such termination,
except for Base Salary which accrued as of the termination date. The term "Total
and Permanent Disability" means the suffering by Executive of a Disability for a
period (whether or not continuous) in excess of ninety (90) days, unless
extended in writing by Company. A Total and Permanent Disability shall be deemed
to commence upon the expiration of such ninety (90) day period.

                                      -3-
<PAGE>
 
                (iii) For purposes hereof, the terms "Disabled" or "Disability"
shall mean the suffering by Executive of a physical or mental condition
resulting from bodily injury, disease, or mental disorder which renders
Executive incapable of continuing each and every one of his or her usual and
customary duties in an efficient manner as an employee of Company, as determined
by the Board of Directors. No Disability shall be deemed to exist until
Executive shall be unable to perform such duties hereunder for seven (7)
consecutive days, and after such Disability continues for seven (7) consecutive
days, then the same shall be deemed to have existed from the first (1st) day of
such Disability. At the end of any Disability (other than a Disability that
results in a Total and Permanent Disability as defined below), Executive shall
return to work, and this Agreement shall continue as though such Disability had
not occurred.

     If Executive desires to return to work at the end of any Disability, but
there is a dispute as to whether Executive is able to perform his or her duties
hereunder or if there is a dispute as to whether Executive is Disabled or has
suffered a Total and Permanent Disability, the issue shall be submitted to a
Board of Arbiters consisting of three (3) persons:  one (1) physician who
specializes in the physical or mental condition which resulted in the Disability
(hereinafter referred to as a "Specialist") shall be appointed on behalf of
Company by the Board of Directors of Company (with Executive having no vote on
this question); the second (2nd) Specialist shall be appointed by Executive and
a third (3rd) Specialist shall be appointed by the two (2) Specialists so
appointed.  If a dispute remains following the completion of this procedure, the
matter shall be determined as set forth in Section 16. below.  If a majority of
the Specialists determine that Executive is able to perform his or her duties
hereunder on a full-time basis, Executive shall be permitted to return to work
under the provisions hereof.  Executive agrees to submit medical records
requested and to submit to such examination and testing requested by such
physician.

     C.  Change In Control.  In the event of a Change in Control (as hereinafter
         -----------------                                                      
defined) of Company and the Executive elects, in his sole discretion, to
terminate his employment hereunder as of a date within six (6) months after the
Change in Control, Executive shall give Company two (2) weeks prior written
notice of such termination and Executive shall be entitled to receive, and
Company shall pay, on the date of the termination of employment an amount equal
to the Executive's then annual base salary rate.

     The term "Change in Control" means:

     (i) The acquisition by any person, entity or "group" within the meaning of
     Sections 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934 ("34
     Act") (excluding, for this purpose, Company, any of subsidiaries, or any
     employee benefit plan of Company or any of its subsidiaries) of beneficial
     ownership (within the meaning of Rule 13d-3 promulgated under the 34 Act)
     of more than 50% of either the then outstanding shares of common stock of
     Company or of the combined voting power of Company's then outstanding
     voting securities entitled to vote generally in the election of directors;
     or

<PAGE>
 
     (ii) Individuals who, as of the date hereof, constitute the board of
     directors of Company ("Incumbent Board") cease for any reason to constitute
     at least a majority of the board of directors, provided that any individual
     becoming a director subsequent to the date hereof whose election, or
     nomination for election by Company's shareholders, was approved by a vote
     of at least a majority of the directors then comprising the Incumbent Board
     shall be considered as though such individual is a member of the Incumbent
     Board; or

     (iii)  Approval of the shareholders of Company of a merger, consolidation
     or other reorganization in each case, with respect to which persons who
     were the shareholders of Company and optionees immediately prior to such
     merger, consolidation or other reorganization, immediately thereafter, do
     not own more than 50% of the combined voting power entitled to vote
     generally in the election of directors of the merged, consolidated or
     reorganized Company's then outstanding voting securities, or of the sale of
     all or substantially all of the assets of Company; provided, however, in
     such event the Change in Control will be deemed to have occurred
     immediately prior to the merger, consolidation or other reorganization.

     The term "Change in Control" shall not include any change in the Board of
Directors of Company as provided in subparagraph (ii) above.

     D.  Termination by Company Without Cause.  In the event Company terminates
         ------------------------------------

         --------------                                                     
Period and Territory contained in this Agreement are reasonably necessary for
the protection of Company's legitimate business interests and that the Territory
is the area in which Executive shall perform (or currently perform) services for
Company; (ii) by having access to information concerning employees, independent
contractors and customers of Company, Executive shall obtain a competitive
advantage as to such parties; (iii) Executive's covenants and agreements
contained in this Agreement are reasonably necessary to protect the interests of
Company in whose favor said covenants and agreements are imposed in light of the
nature of Company's Business and Executive's involvement in such Business; (iv)
the restrictions imposed by this Agreement are not greater than are necessary
for the protection of Company in light of the substantial harm that Company
shall suffer should Executive breach any of the provisions of said covenants or
agreements and (v) Executive's covenants and agreements contained in this
Agreement form material consideration for this Agreement, the Acquisition
Agreement and Executive's employment by Company.

     10.  Remedy for Breach.  Executive agrees that the remedies at law of
          -----------------                                               
Company for any actual or threatened breach by Executive of the covenants
contained in Sections 6. through 8. of this Agreement would be inadequate and
that Company shall be entitled to specific performance of the covenants in such
paragraphs, including entry of an ex parte, temporary restraining order in state
or federal court, preliminary and permanent injunctive relief against activities
in violation of such paragraphs, or both, or other appropriate judicial remedy,
writ or order, in addition to any damages and legal expenses (including
attorney's fees) which Company may be legally entitled to recover.  Executive
acknowledges and agrees that the covenants contained in Sections 6. through 8.
of this Agreement shall be construed as agreements independent of any other
provision of this or any other agreement between the parties hereto, and that
the existence of any claim or cause of action by Executive against Company,
whether predicated upon this or any other agreement, shall not constitute a
defense to the enforcement by Company of said covenants.

     11.  No Prior Agreements.  Executive hereby represents and warrants to
          -------------------                                              
Company that the execution of this Agreement by Executive and Executive's
employment by Company and the

                                      -7-
<PAGE>
 
performance of Executive's duties hereunder shall not violate or be a breach of
any agreement with a former employer, client or any other person or entity.

     12.  Assignment; Binding Effect.  Executive understands that Executive has
          --------------------------                                           
been selected for employment by Company on the basis of Executive's personal
qualifications, experience and skills.  Executive agrees, therefore, that
Executive cannot assign all or any portion of Executive's performance under this
Agreement.  Subject to the preceding two (2) sentences and the express
provisions of Section 13. below, this Agreement shall be binding upon, inure to
the benefit of and be enforceable by the parties hereto and their respective
heirs, legal representatives, successors and assigns.

     13.  Complete Agreement.  This Agreement is not a promise of future
          ------------------                                            
employment.  Executive has no oral representations, understandings or agreements

all the terms of this Agreement, and it cannot be varied, contradicted or
supplemented by evidence of any prior or contemporaneous oral or written

party waiving the benefit of such term.

          ----------------------                                           
invalid or inoperative, the other portions of this Agreement shall be deemed
valid and operative and, so far as is reasonable and possible, effect shall be
given to the intent manifested by the portion held invalid or inoperative.  This
Agreement shall be enforced separately and independently of any other agreement
involving the parties hereto.  The Section headings herein are for reference
purposes only and are not intended in any way to describe, interpret, define or
limit the extent or intent of the Agreement or of any part hereof.

     16.  Arbitration.  Except as otherwise set forth in Sections 4.B.(iii) and
          -----------                                                          
6. through 10., any dispute, controversy or claim arising out of, relating to or
in connection with, this Agreement, or the breach, termination or validity
thereof shall be finally settled by arbitration conducted in accordance with
this Section.  The arbitration shall be conducted in accordance with the Rules
of the American Arbitration Association (the "AAA") in effect at the time of the
arbitration, except as they may be modified herein or by mutual agreement of the
parties.  The seat of the arbitration shall be Atlanta, Georgia, and each party
hereto irrevocably submits to the jurisdiction of the arbitration panel in
Atlanta, Georgia.  The arbitration shall be conducted by three (3) arbitrators.
The party initiating arbitration (the "Claimant") shall identify its arbitrator
within twenty (20) days of receipt of the Request and shall notify the Claimant
of such appointment in writing.  If the Respondent fails to identify an
arbitrator within such twenty (20) day period, the arbitrator named in the
Request shall decide the controversy or claim as the sole arbitrator.
Otherwise, the two (2) arbitrators appointed by the parties shall appoint a
third (3rd) arbitrator within twenty (20) days after the Respondent has notified
Claimant of the appointment of the Respondent's arbitrator.  When the third
(3rd) arbitrator has accepted the appointment, the two (2) party-appointed
arbitrators shall promptly notify the parties of the appointment.  If the two
(2) arbitrators appointed by the parties fail or are unable to so appoint a
third (3rd) arbitrator, then the appointment of the third (3rd) arbitrator shall
be made by the AAA, which shall promptly notify the parties of the appointment.
The third (3rd) arbitrator shall act as chair of the panel.  The arbitration
award shall be in writing and shall be final and binding on the parties.  The
award may include an award of costs, including reasonable attorneys' fees and
disbursements.  Judgment upon the award may be entered by any court having
jurisdiction thereof or having jurisdiction over the parties or their assets.
Notwithstanding the foregoing, the parties may apply to any court of competent
jurisdiction for an ex parte temporary restraining order, preliminary
injunction, or other interim or conservatory relief, as necessary, without
breach of this Section and without any abridgment of the powers of the
arbitrators.
