                  (b)      Stock Options. Pursuant and subject to the terms and
conditions of the Amended and Restated 1998 Stock Option Plan between the
Company and Employee of even date herewith (the "Stock Option Plan"), Employee

time be prescribed by the Company.

                  (d)      Other Business Expenses. The Company shall reimburse
Employee for his actual out-of-pocket, business expenses that are incurred by
Employee and are reasonable and necessary in relation to and in furtherance of
Employee's performance of his duties to the Company. Such reimbursement shall be

provision of substantiating documents of said expenses as may be reasonably
requested by the Company.

                  (e)      Vacation. Employee shall be entitled to twenty-one
(21) days Paid Time Off (PTO) per year for vacation. Illness, other personal
time away from work, and holidays shall be allowed in accordance with the

         4.       TERMINATION. This Agreement may be terminated prior to the
expiration of the term as follows:

<PAGE>   3


mental illness, injury or incapacity for either (i) a period of ninety (90)
consecutive days or (ii) more than one hundred-eighty (180) days in the
aggregate in any twelve (12) month period, then the Company may terminate
Employee's employment upon written notice to Employee. While receiving
disability income payments under the Company's disability income plan, Employee
shall not be entitled to receive any Base Salary hereunder, but shall continue
to participate in the Company's benefit plans, to the extent permitted by such
plans, until the termination of his employment.

                  (b)      For Cause. The Company may terminate Employee's
employment hereunder for Cause at any time upon notice to Employee setting forth
in reasonable detail the nature of such Cause. In the event that the Company
terminates Employee's employment for Cause (or Employee resigns from his
employment with the Company), the Company shall not be obligated to pay any
salary, severance, or other compensation to Employee after the effective date of
termination, other than accrued and unpaid Base Salary and bonus earned through
the date of termination.

                  (c)      Without Cause. In the event the Company terminates
this Agreement without Cause prior to December 27, 2001, or the parties do not
agree to renew this Agreement for a successive one (1) year term, after December
26, 2001, then Employee shall be entitled to (i) severance pay in the form of
continuation of his annualized Base Salary through December 26, 2002, which
shall be paid in accordance with the Company's regular payroll practices and
subject to any and all withholdings pursuant to applicable law, and (ii) a pro
rata portion of his incentive bonus, if any, contemplated by Section 3(a) for
the quarter in which his employment terminated based upon the number of days in
the quarter elapsed prior to such termination. In addition, the Company shall
continue to provide, through COBRA or otherwise, medical insurance coverage
contemplated by Section 3(c) for a period of twelve months following the date of
Employee's termination without Cause prior to December 27, 2001, or until
Employee's earlier commencement of employment with any other entity. Payment of
the severance benefits set forth herein shall be subject to Employee's continued
compliance with the provisions of Section 5 hereof.

         5.       PROTECTIVE COVENANTS. Employee is, and will become during the
course of employment, intimately familiar with Confidential Information, Trade
Secrets, products and services, and other property of the Company. The
protection of the Company requires that all such property and information must
remain the sole and private property of the Company to be used only for the
Company's benefit, not to be disclosed to any other party nor used by Employee
against the Company or for the benefit of any other person. Employee shall, upon
request of the Company, and without request promptly on termination of
employment, deliver all Company Property in Employee's possession or control to
the Company. Employee acknowledges and agrees that title to all Company Property
is vested in the Company. In addition, Employee warrants, represents, covenants
and agrees, during the term of his employment and for the periods described
below, as follows:

                  (a)      Covenant Not to Solicit Business from Certain
Customers. By virtue of his position with the Company, Employee shall be given
an opportunity to, and shall have an


                                       3

<PAGE>   4


obligation to, participate in strategic planning with respect to competitors of
the Company and shall be made privy to the Company's marketing strategy, product
development, pricing, timing and other matters specifically designed to address
market competition. In addition, Employee acknowledges that during the course of
his employment by the Company, Employee shall have a duty to, and shall be given
an opportunity to, make contact with and strengthen ties with Customers and
potential Customers of the Company. For a period through December 27, 2002,
Employee shall not, directly or indirectly, for himself or any other person or
entity, solicit any Customer for the purchase or license by such Customer of any
product or service competitive with any of the products and services which the
Company offered within, or, with Employee's knowledge, contemplated offering
during, the one-year period preceding termination of Employee's employment.

                  (b)      Covenant Not to Solicit Employees. For a period of
two (2) years following the date of termination of his employment with the
Company or expiration of this Agreement, Employee shall not, directly or
indirectly, for himself or any other person or entity, employ or solicit the
employment of any employee of the Company for the purpose of causing such
employee to take employment with Employee or any other person or entity until
such employee or former employee has ceased to be employed by the Company for a
period of six (6) months.

                  (c)      Covenant Not to Disclose Confidential Information or
Trade Secrets. Employee shall not disclose to any person whatsoever or use any
Trade Secrets or Confidential Information of the Company, other than as
necessary in the fulfillment of his duties to the Company in the course of
employment. This paragraph shall be effective during the term of this Agreement
and for a period of two (2) years after termination of employment with the
Company or expiration of this Agreement with respect to all Confidential
Information, and shall remain in effect with respect to all Trade Secrets so
long as such information remains a trade secret under applicable law.

                  (d)      Assistance in Litigation. Employee shall, upon
reasonable notice, furnish such information and assistance to the Company as may
reasonably be required by the Company in connection with any litigation in which
it is, or may become, a party, and which arises out of facts and circumstances
known to Employee. The Company shall promptly reimburse Employee for his
out-of-pocket expenses incurred in connection with the fulfillment of his
obligations under this subsection. Provided, however, that Employee's
obligations under this subsection shall only exist during the term of this
Agreement and during the period, if any, during which he receives compensation
from the Company following the termination or expiration of this Agreement.

                  (e)      Breach or Invalidity of Covenant. The parties
expressly acknowledge and agree that the severance benefits provided for in
Section 4 hereof are in consideration for, and are directly dependent upon, the
Employee's agreement to be bound by and performance of the provisions of this
Section 5, and in the event Employee breaches the covenants contained herein,
then the parties agree that there shall be a total failure of consideration for
the severance


                                       4

obligations set forth in Section 4, and Employee shall not be entitled to
receive any severance benefits.

         6.       WORK PRODUCT; INVENTIONS.

all preliminary designs and drafts, all other works of authorship, all
derivative works and patentable and unpatentable inventions and improvements,

title or interest in and to any of the Work Product (including without
limitation all worldwide copyrights, trademarks, patents or other intellectual
property rights therein) does and shall not vest automatically in and with the

otherwise transfer to the Company, and the Company's respective successors and
assigns, all such right, title and interest in and to the Work Product with no
requirement of further consideration from or action by Employee or the Company.

                  (c)      Registration Rights. The Company shall have the

such copyright registrations. The Company shall also have the exclusive
worldwide right to file applications for and obtain (i) patents on and for any

stead to execute, register and file any such assignments, applications,
registrations, renewals and extensions and to do all other lawfully permitted
acts to further the registration, prosecution and issuance of patents, copyright
or similar protections with the same legal force and effect as if executed by
Employee.

of Employee's employment hereunder for whatever reason, Employee shall, if

subpart(s) thereof) and this Agreement valid and enforceable. Any illegal or
unenforceable provision (or subpart thereof), or any modification by any court,
shall not affect the remainder of this Agreement, which shall continue at all
times to be valid and enforceable.

                  (a)      Mutual Non-Disparagement. The Company and Employee

                  (b)      Press Releases. Other than as required by applicable
law, the parties agree that no public announcement or similar publicity with
respect to this Agreement or the termination of Employee's employment with the
Company will be issued, if at all, unless the parties agree in writing as to the
time, manner and content of such announcement or publicity. Unless consented to
by the Company in advance or required by law, Employee shall keep this Agreement
strictly confidential and may not make any disclosure of this Agreement or any
of its terms or provisions to any person. The parties will consult with each
other in good faith concerning the means by which the Company's employee's,
customers and suppliers and others having dealings with Employee will be
informed of the termination of Employee's employment with the Company.

         11.      ENTIRE AGREEMENT; MODIFICATION; GOVERNING LAW. This Agreement

Agreement shall be construed as drafted by both of them.

         13.      REVIEW AND VOLUNTARINESS OF AGREEMENT. Employee acknowledges
Employee has had an opportunity to read, review, and consider the provisions of
this Agreement, that


                                       6

<PAGE>   7


Employee has in fact read and does understand such provisions, and that Employee
has voluntarily entered into this Agreement.

         14.      ATTORNEYS' FEES. In the event that either party initiates
litigation as to a claim for damages, injunction, specific performance or
recovery of money (as against the other party) due by reason of this Agreement
or breach of such other party's obligations under any of the terms or provisions
hereof, the non-prevailing party in any such cause of action shall pay, in
addition to such sums as may be due or such other relief to which the prevailing
party may be entitled, reasonable attorneys' fees and related costs of the
prevailing party.

         15.      NON-WAIVER. The failure of a party to insist upon or enforce
strict performance of any provision of this Agreement or to exercise any rights
or remedies thereunder will not be construed as a waiver by such party to assert
or rely upon any such provision, right or remedy in that or any other instance.

         16.      NO CONFLICTING OBLIGATIONS. Employee hereby acknowledges and
represents that Employee's execution of this Agreement and performance of
employment-related obligations and duties for the Company as set forth hereunder
will not cause any breach, default or violation of any other employment,
non-disclosure, confidentiality, non-competition or other agreement to which
Employee may be a party or otherwise bound. Employee hereby agrees that he will
not use in the performance of his duties for the Company (or otherwise disclose
to the Company) any trade secrets or confidential information of any prior
employer or other person or entity if and to the extent that such use or
disclosure may cause a breach or violation of any obligation or duty owed to
such employer, person, or entity under any agreement or applicable law.

         17.      FORUM; ENFORCEMENT. In the event of litigation arising from
this Agreement, each party hereby expressly consents to jurisdiction and venue
in any State or Federal Court sitting in Cobb County, State of Georgia, and
waives any objections to such jurisdiction and venue. Employee further agrees
that if Employee were to breach the provisions of Section 5 or 6 hereof, the
Company would be irreparably harmed and therefore, in addition to any other
remedies available at law, the Company shall be entitled to seek equitable
relief, including without limitation, specific performance and preliminary and
permanent injunction, against any breach or threatened breach of said Sections 5
and 6, without having to post bond.

         18.      NOTICES. Any notice or other communications under this
Agreement shall be in writing, signed by the party making the same, and shall be
