        month period of securities of the Company representing an aggregate of
        fifty percent (50%) or more of the combined voting power of the
        Company's then outstanding securities; provided, that for purposes of
        this Paragraph (a), "acquisition" shall not include shares which are
        received by a person through gift, inheritance, under a will or
        otherwise through the laws of descent and distribution;

                        (2) During any period of two consecutive years,
        individuals who at the beginning of such period constitute the Board of

<PAGE>   4
to any Person that offers or provides products or services of the types provided
by the Company in the Business.

         g. DISPARAGEMENT. Employee shall not at any time make false, misleading
or disparaging statements about the Company, including the Business, management,
employees and Customers.

         h. PRIOR AGREEMENTS. Employee represents and warrants that Employee is
not under any obligation, contractual or otherwise, limiting, impairing or
affecting Employee's performance of Services. Upon execution of this Agreement,
Employee shall give the Company any agreement with a prior employer or other
Person purporting to limit or affect, in any way, Employee's ability to work for
the Company, to solicit customers or potential customers or employees or to use
any type of information.

         i. FUTURE EMPLOYMENT OPPORTUNITIES. Prior to and for two (2) years
after the Temination Date, Employee shall (a) provide any prospective employer
with a copy of this Agreement, and (b) upon accepting any position, provide the
Company with the employer's name and a description of the services, if any,
Employee will provide for such employer.

         j. WORK FOR HIRE ACKNOWLEDGMENT; ASSIGNMENT. All writings, drawings,
photographs, tapes, recordings, computer programs and other works in any
tangible medium of expression, regardless of the form of medium, which have been
or are prepared by Employee, or to which Employee contributes, in connection
with Employee's employment by the Company (collectively the "Works") and all
copyrights and other rights in and to the Works, belong solely, irrevocably and
exclusively throughout the world to the Company as works made for hire. However,
to the extent any court or agency should conclude that the Works (or any of
them) do not constitute or qualify as a "work made for hire," Employee hereby
assigns, grants and delivers, solely, irrevocably, exclusively and throughout
the world to the Company all copyrights and other rights to the Works. Employee
also agrees to cooperate with the Company and to execute such other further
grants and assignments of all rights as the Company from time to time reasonably
may request for the purpose of evidencing, enforcing, registering or defending
its ownership of the Works and the copyrights in them, and Employee hereby
irrevocably constitutes and appoints the Company as Employee's agent and
attoney-in-fact, with full power of substitution, in Employee's name, place and
stead, to execute and deliver any and all such assignments or other instruments
which Employee shall fail or refuse promptly to execute and deliver, this power
and agency being coupled with an interest and being irrevocable. Without
limiting the preceding provisions of this Paragraph 8(j), Employee agrees that
the Company may edit and otherwise modify, and use, publish and otherwise
exploit, the Works in all media and in such manner as the Company, in its
discretion, may determine.

         k. INVENTIONS, IDEAS AND PATENTS. Employee shall disclose promptly to
the Company (which shall receive it in confidence), and only to the Company, any
invention or idea
<PAGE>   5
of Employee (developed alone or with others) conceived or made during Employee's
employment by the Company (or, if related to the Business, during employment or
within one year after the Termnination Date). Employee assigns to the Company
any such invention or idea in any way connected with Employee's employment or
related to the Business, research or development of the Company, or demonstrably
anticipated research or development of the Company, and will cooperate with the
Company and sign all papers deemed necessary by the Company to enable it to
obtain, maintain, protect and defend patents covering such inventions and ideas
and to confirm the exclusive ownership of the Company of all rights in such
inventions, ideas and patents, and irrevocably appoints the Company as its agent
to execute and deliver any assignments or documents Employee fails or refuses to
execute and deliver promptly, this power and agency being coupled with an
interest and being irrevocable. This constitutes written notification to
Employee that this assignment does not apply to an invention for which no
equipment, supplies, facility or trade secret information of the Company or any
Customer was used and which was developed entirely on Employee's own time,
unless (a) the invention relates (i) directly to the Business or (ii) to the
actual or demonstrably anticipated research or development of the Company, or
(b) the invention results from any work performed by Employee for the Company.

         l. INDEPENDENCE OF COVENANTS. The covenants contained herein shall be
construed as agreements independent of each other and of any other provision of
this or any other contract between the parties hereto, and the existence of any
claim or cause of action by Employee against the Company, whether predicated
upon this or any other contract, shall not constitute a defense to the
enforcement by the Company of said covenants.

         m. RIGHT TO INJUNCTIVE RELIEF. Employee recognizes and agrees that the
injury the Company will suffer in the event of the Employee's breach of any
covenant or agreement contained herein cannot be compensated by monetary damages
alone, and Employee therefore agrees that the Company, in addition and without
limiting any other remedies or rights that it may have, either under his
Agreement or otherwise, shall have the right to obtain an injunction against
Employee from any court of competent jurisdiction enjoining any such breach.

8.       TERMINATION.

         a. This Agreement and the employment of Employee may be terminated as 
follows:

                 (1) By the Company (i) pursuant to Paragraph 5, 6 or 7, (ii)
         upon commission by the Employee of any felony or material misdemeanor
         under federal, state or local laws or ordinances, except traffic
         violations or (iii) upon the failure of Employee to diligently or
         competently discharge the duties assigned to him pursuant to this
         Agreement; or

         of any representation or warranty made to the Company herein or in any
         other agreement, document or instrument executed by Employee and
         delivered to the Company, or should any representation or warranty made
         by Employee hereunder or thereunder prove to have been false or
         misleading in any material respect when made or furnished; or

                 (4) By the Company upon the death of Employee.

         b. In the event Employee is terminated by the Company for any reason

shall be entitled only to compensation accrued through the date of termination
and all benefits accrued as of such date, and shall not be entitled to any
portion of the payment set forth in clause (ii) of this Paragraph (b).

         c. For purposes of this Agreement, the term "Applicable Period" means:
(i) ninety (90) days, in the case of a notice given to Employee prior to the
first anniversary of the date on which Employee commenced his employment with
the Company or its affiliate (the "Employment Date"); (ii) one hundred eighty
(180) days, in the case of a notice given to Employee on or after the first

(iii) one (1) year, in the case of a notice given to Employee on or after the
second anniversary of his Employment Date.


    9.   MISCELLANEOUS.

         a. This Agreement may be assigned by the Company to any successor in 
interest to its business, which successor in interest shall be bound herein to 
the same extent as the Company. Employee agrees to perform his duties for such
successor in interest to the same extent as he would for the Company.

         b. This is a personal agreement on the part of Employee and may not be

<PAGE>   7
                 c. The waiver by either party of a breach of any provision of

         accordance with the laws of the State of Georgia.
