         -----------------
benefit plans and policies currently and hereafter maintained by the Company and

     4.  Compensation.
         ------------

         (a)   Base Salary. For the period from the Effective Date to the
               -----------
Full-Time Date, the Company shall pay Executive a salary of $5,000. Beginning on
the Full-Time Date and for the remainder of the term of this Agreement, the
Company shall pay Executive as compensation for her services a base salary at

         (b)   Bonuses. Executive shall be entitled to bonuses as follows:
               -------

vision, disability, life insurance, accidental death and dismemberment, and
travel accident insurance plans and programs) to the extent generally applicable
to peer executives of the Company.

         (e)   Subsequent Agreements. If, after the Effective Date, the
               ---------------------

change in control agreement, or similar change-in-control protection for any
member of senior management of the Company (other than the Chief Executive
Officer), which is on terms more favorable than in this Agreement, such more
favorable terms and agreements (other than with respect to salary, bonuses, and
other dollar amounts, which shall be tailored on an individual basis) will be
made available to Executive.

     5.  Termination of Employment.
         -------------------------

         (a)   The Company may terminate Executive's employment for "Cause" or
without Cause. Executive's termination of employment shall not be deemed to be
for Cause, unless and until (1) Executive has been given the opportunity, on
reasonable advance notice, to be heard before the Board, together with counsel
to Executive, and (2) there shall have been delivered to Executive a copy of a
resolution thereafter duly adopted by the affirmative vote of not less than
three-quarters of the entire membership of the Board (excluding Executive, if


                                       -3-

<PAGE>

Executive is a member of the Board) finding that, in the good faith opinion of
the Board, Executive is guilty of conduct constituting Cause, and specifying the
particulars thereof in detail.

          "Cause" means (a) Executive's willful and continued failure to perform
substantially Executive's duties as contemplated by Section 1 (except as a
result of Executive's incapacity due to physical or mental illness or injury),
after a written demand for substantial performance is delivered to Executive by
the Board or the Chief Executive Officer of the Company which specifically
identifies the manner in which the Board believes that Executive has not
substantially performed Executive's duties, (b) Executive's willful engaging in
illegal conduct or gross misconduct that is demonstrably injurious to the
Company, or (c) final conviction of a felonious crime. For purposes of this
definition, no act or failure to act on the part of Executive shall be
considered "willful" unless it is done, or omitted to be done, by Executive in
bad faith or without reasonable belief that Executive's action or omission was
in the best interests of the Company. Any act, or failure to act, based upon
authority given pursuant to a resolution duly adopted by the Board or upon the
instruction of the Chief Executive Officer of the Company or based upon the
advice of outside counsel for the Company shall be conclusively presumed to be
done, or omitted to be done, by Executive in good faith and in the best
interests of the Company.

          Executive will be deemed to have been terminated by the Company if:
(a) Executive is assigned any duties inconsistent in any respect with
Executive's position (including status, offices, titles and reporting
requirements), authority, duties or responsibilities as contemplated by Section
1(a), or any other diminution in such position, authority, duties or
responsibilities (whether or not occurring solely as a result of the Company's
ceasing to be a publicly traded entity), other than an isolated, insubstantial
and inadvertent action not taken in bad faith that is remedied by the Company
promptly after receipt of notice thereof given by Executive; (b) the Company
fails to comply with any of the provisions of Section 4, 5, 6, 7 or 8, other
than an isolated, insubstantial and inadvertent failure not occurring in bad
faith that is remedied by the Company promptly after receipt of notice thereof
given by Executive; or (c) the Company requires Executive to be based at any
office or location (1) more than 35 miles from the Company's current corporate
offices or (2) other than the Company's principal offices; or (d) a failure by
the Company to provide change of control protections acceptable to Executive
within six months of the date hereof, provided that Executive gives the Company
written notice within sixty (60) days after expiration of such period that
acceptable change of control provisions have not been made available to
Executive and constitute a deemed termination of Executive under this
subparagraph (d).

          (b) Upon termination of employment (or deemed termination) of
Executive other than for Cause, the Company shall pay Executive a severance
payment on the date of termination of employment (or deemed termination) equal
to six months of the then existing Base Salary, plus one additional month of
Base Salary for each year of employment by the Company or one of its affiliated
companies. Executive shall not be entitled to any additional payments (other
than accrued and unpaid compensation and benefits) if Executive's employment is
terminated for Cause.

     6.   Fringe Benefits. Executive shall be entitled to fringe benefits in
          ---------------
accordance with the plans, practices, programs and policies of the Company and
its affiliated companies as in

                                       -4-

effect generally at any time with respect to peer executives of the Company and
its affiliated companies.

     7.  Office and Support Staff; Professional Memberships.
         --------------------------------------------------

         (a) Executive shall be entitled to an office or offices of a size and
with furnishings and other appointments, and to secretarial and other
assistance, as provided generally at any time with respect to peer executives of
the Company and its affiliated companies; provided that in no event shall
Executive have less than one full time assistant devoted solely to legal
services to the Company. The Company will also pay costs of moving Executive's
files, documents, furniture and other office furnishings to its principle
offices.

         (b) The Company shall (i) pay to maintain Executive's Georgia bar
license and memberships and any other state in which the Company requests
Executive to practice law, including required continuing legal education and
(ii) pay for American Bar Association, American Society of Corporate Secretaries
and other reasonable professional association membership fees.

     8.  Vacation. Executive shall be entitled to paid vacation in accordance
         --------
with the plans, policies, programs and practices of the Company and its
affiliate companies as in effect generally at any time with respect to peer
executives of the Company and its affiliated companies, but in no event shall
Executive have less than four weeks paid vacation.

     9.  Expenses. The Company will promptly pay or reimburse Executive for all
         --------
reasonable travel entertainment or other expenses incurred by Executive in the
furtherance of or in connection with the performance of Executive's duties
hereunder in accordance with the Company's established policies applicable to
other peer executives of the Company and its affiliated companies.

     10. Assignment. This Agreement shall be binding upon and inure to the
         ----------
benefit of (a) the heirs, executors and legal representatives of Executive upon
Executive's death or incapacity, and (b) any successor or assign of the Company.
Any such successor of the Company shall be deemed substituted for the Company
under the terms of this Agreement for all purposes. As used herein, "successor"
shall include any person, firm, corporation or other business entity which at
any time, whether by purchase, merger or otherwise, directly or indirectly
acquires all or substantially all of the assets of business of the Company. None
of the rights of Executive to receive any form of compensation payable pursuant
to this Agreement shall be assignable or transferable except through a
testamentary disposition or by the laws of descent and distribution upon the
death of Executive. Any attempted assignment, transfer, conveyance or other
disposition (other than as aforesaid) of any interest in the rights of Executive
to receive any form of compensation hereunder shall be null and void.

     The Company shall require any successor (whether direct or indirect, by
purchase, merger, consolidation or otherwise) to all or substantially all of the
business and/or assets of the Company to assume expressly and agree to perform
this Agreement in the same manner and to the same extent that the Company would
be required to perform it if no such succession had taken place.

               (ii)  Nonsolicitation of Protected Employees. Executive
                     --------------------------------------
     understands and agrees that the relationship between the Company and each
     of its Protected Employees constitutes a valuable asset of the Company and
     may not be converted to Executive's own use. Accordingly, Executive hereby
     agrees that during the Restricted Period Executive shall not directly or
     indirectly on Executive's own behalf or as a Principal or Representative of
     any Person or otherwise solicit or induce any Protected Employee to

     Customer on The Company's behalf; (b) she was responsible for supervising

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

               (i)  Rights and Remedies Upon Breach. In the event Executive
                    -------------------------------

     Restrictive Covenants, the Company shall have the right and remedy to
     enjoin, preliminarily and permanently, Executive from violating or
     threatening to violate the Restrictive Covenants and to have the
     Restrictive Covenants specifically enforced by any court of competent
     jurisdiction, it being agreed that any breach or threatened breach of the
     Restrictive Covenants would cause irreparable injury to the Company and
     that money damages would not provide an adequate remedy to the Company.
     Such equitable right and remedy shall be in addition to, and not in lieu
     of, any other rights and remedies available to the Company at law or in
     equity. In no event shall an asserted violation of the provisions of this
     section 12 constitute a basis for deferring or withholding any amounts
     otherwise payable to Executive under this Agreement.

               (ii) Severability of Covenants. Executive acknowledges and agrees
                    -------------------------
     that the Restrictive Covenants are reasonable and valid in time and scope
     and in all other respects. The covenants set forth in this Agreement shall
     be considered and construed as separate and independent covenants. Should
     any part or provision of any covenant be held invalid, void or
     unenforceable in any court of competent jurisdiction, such invalidity,
     voidness or unenforceability shall not render invalid, void or
     unenforceable any other part or provision of this Agreement. If any portion
     of the foregoing provisions is found to be invalid or unenforceable by a
     court of competent jurisdiction because its duration, the territory, the
     definition of activities or the definition of information covered is
     considered to be invalid or unreasonable in scope, the invalid or
     unreasonable term shall be redefined, or a new enforceable term provided,
     such that the intent of the Company and Executive in agreeing to the
     provisions of this Agreement will not be impaired and the provision in
     question shall be enforceable to the fullest extent of the applicable laws.

     13.  Entire Agreement. This Agreement and the documents referenced herein
          ----------------
represent the entire agreement and understanding between the Company and
Executive concerning the subject matter hereof, and supersede and replace any
and all prior agreements and understandings concerning such subject matter.

     14.  Arbitration and Equitable Relief.

of Employment Disputes then in effect of the American Arbitration Association

     15.  Severability. In the event that any provision hereof becomes or is
          ------------
