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

                 ---------
agrees as follows:

     (a)  No Liens; No Sale of Collateral.  The Pledgor will not create, assume,
          -------------------------------

Robert A. Yellowlees to be a general partner of the Pledgor, during such time as

     Section 5.  Additional Shares.  The Pledgor agrees that, until this
                 -----------------
Agreement has terminated in accordance with its terms, any additional Securities
at any time issued to the Pledgor or otherwise acquired by the Pledgor on
account of the Securities shall be promptly delivered or otherwise transferred
to the Pledgee as additional Collateral and shall be subject to the Lien of, and
the terms and conditions of, this Agreement.

     Section 6.  Voting Rights; Dividends, etc.
                 ------------------------------

     (a)  So long as no Event of Default shall have occurred and be continuing:

          (i)   the Pledgor shall be entitled to exercise any and all voting
     and/or consensual rights and powers accruing to an owner of the Collateral
     or any part thereof for any purpose not inconsistent with the terms and
     conditions of this Agreement or any agreement giving rise to or otherwise
     relating to any of the Secured Obligations; provided, however, that the
                                                 --------  -------
     Pledgor shall not exercise, or refrain from exercising, any such right or
     power if any such action would have a materially adverse effect on the
     value of such Collateral in the judgment of the Pledgee; and

          (ii)  the Pledgor shall be entitled to retain and use any and all cash
     dividends paid on the Collateral, but any and all stock and/or liquidating
     dividends, other distributions in property, return of capital or other
     distributions made on or in respect of Securities, whether resulting from a
     subdivision, combination or reclassification of outstanding Securities or
     received in exchange for Collateral or any part thereof or as a result of
     any merger, consolidation,

                                      -3-
<PAGE>

     acquisition or other exchange of assets, or otherwise, shall be and become
     part of the Collateral pledged hereunder and, if received by the Pledgor,
     shall forthwith be delivered to the Pledgee to be held as collateral
     subject to the terms and conditions of this Agreement.

The Pledgee agrees to execute and deliver to the Pledgor, or cause to be
executed and delivered to the Pledgor, as appropriate, at the sole cost and
expense of the Pledgor, all such proxies, powers of attorney, dividend orders
and other instruments as the Pledgor may reasonably request for the purpose of
enabling the Pledgor to exercise the voting and/or consensual rights and powers
which Pledgor is entitled to exercise pursuant to clause (i) above and/or to
receive the dividends which Pledgor is authorized to retain pursuant to clause
(ii) above.

     (b)  Upon the occurrence and during the continuance of an Event of Default,
all rights of the Pledgor to exercise the voting and/or consensual rights and
powers which Pledgor is entitled to exercise pursuant to subsection (a)(i) above
and/or to receive the dividends which Pledgor is authorized to receive and
retain pursuant to subsection (a)(ii) above shall cease, and all such rights
thereupon shall become immediately vested in the Pledgee, which shall have, to
the extent permitted by law, the sole and exclusive right and authority to
exercise such voting and/or consensual rights and powers which the Pledgor shall
otherwise be entitled to exercise pursuant to subsection (a)(i) above and/or to
receive and retain the dividends which the Pledgor shall otherwise be authorized
to retain pursuant to subsection (a)(ii) above.  Any and all money and other
property paid over to or received by the Pledgee pursuant to the provisions of
this subsection (b) shall be retained by the Pledgee as additional collateral
hereunder and shall be applied in accordance with the provisions of Section 8.
If the Pledgor shall receive any dividends or other property which it is not
entitled to receive under this Section, the Pledgor shall hold the same in trust
for the Pledgee, without commingling the same with other funds or property of or
held by the Pledgor, and shall promptly deliver the same to the Pledgee upon
receipt by the Pledgor in the identical form received, together with any
necessary endorsements.

     Section 7.  Remedies upon Default.
                 ---------------------

     (a)  In addition to any right or remedy that the Pledgee may have under the
Notes or otherwise under applicable law, if an Event of Default shall have
occurred, the Pledgee may exercise any and all the rights and remedies of a
secured party under the Uniform Commercial Code as in effect in any applicable
jurisdiction (the "Code") and may otherwise sell, assign, transfer, endorse and
deliver the whole or, from time to time, any part of the Collateral at a public
or private sale or on any securities exchange, for cash, upon credit or for
other property, for immediate or future delivery, and for such price or prices
and on such terms as the Pledgee in its discretion shall deem appropriate.  The
Pledgee shall be authorized at any sale (if it deems it advisable to do so) to
restrict the prospective bidders or purchasers to Persons who will represent and
agree that they are purchasing the Collateral for their own account in
compliance with the Securities Act

                                      -4-
<PAGE>

and upon consummation of any such sale the Pledgee shall have the right to
assign, transfer, endorse and deliver to the purchaser or purchasers thereof the
Collateral so sold. Each purchaser at any sale of Collateral shall take and hold
the property sold absolutely free from any claim or right on the part of the
Pledgor, and the Pledgor hereby waives (to the fullest extent permitted by
applicable law) all rights of redemption, stay and/or appraisal which the
Pledgor now has or may at any time in the future have under any applicable law
now existing or hereafter enacted. The Pledgor agrees that, to the extent notice
of sale shall be required by applicable law, at least 10 days' prior written
notice to the Pledgor of the time and place of any public sale or the time after
which any private sale is to be made shall constitute reasonable notification,
but notice given in any other reasonable manner or at any other reasonable time
shall constitute reasonable notification. Any such public sale shall be held at
such time or times within ordinary business hours and at such place or places as
the Pledgee may fix and shall state in the notice or publication (if any) of
such sale. At any such sale, the Collateral, or portion thereof to be sold, may
be sold in one lot as an entirety or in separate parcels, as the Pledgee may
determine in its sole and absolute discretion. The Pledgee shall not be
obligated to make any sale of the Collateral if it shall determine not to do so
regardless of the fact that notice of sale of the Collateral may have been
given. The Pledgee may, without notice or publication, adjourn any public or
private sale or cause the same to be adjourned from time to time by announcement
at the time and place fixed for sale, and such sale may, without further notice,
be made at the time and place to which the same was so adjourned. In case the
sale of all or any part of the Collateral is made on credit or for future
delivery, the Collateral so sold may be retained by the Pledgee until the sale
price is paid by the purchaser or purchasers thereof, but the Pledgee shall not
incur any liability to the Pledgor in case any such purchaser or purchasers
shall fail to take up and pay for the Collateral so sold and, in case of any
such failure, such Collateral may be sold again upon like notice. At any public
sale made pursuant to this Agreement, the Pledgee, to the extent permitted by
applicable law, may bid for or purchase, free from any right of redemption, stay
and/or appraisal on the part of the Pledgor (all said rights being also hereby
waived and released to the extent permitted by applicable law), any part of or
all the Collateral offered for sale and may make payment on account thereof by
using any claim then due and payable to the Pledgee from the Pledgor as a credit
against the purchase price, and the Pledgee may, upon compliance with the terms
of sale and to the extent permitted by applicable law, hold, retain and dispose
of such property without further accountability to the Pledgor therefor. For
purposes hereof, a written agreement to purchase all or any part of the
Collateral shall be treated as a sale thereof; the Pledgee shall be free to
carry out such sale pursuant to such agreement and the Pledgor shall not be
entitled to the return of any Collateral subject thereto, notwithstanding the
fact that after the Pledgee shall have entered into such an agreement all Events
of Default may have been remedied or the Secured Obligations may have been paid
in full as herein provided. The Pledgor hereby waives any right to require any
marshaling of assets and any similar right.

     (b)  In addition to exercising the power of sale herein conferred upon it,
the Pledgee shall also have the option to proceed by suit or suits at law or in
equity to

                                      -5-
<PAGE>

foreclose this Agreement and sell the Collateral or any portion thereof pursuant
to judgment or decree of a court or courts having competent jurisdiction.

     (c)  Upon the occurrence of an Event of Default, the Pledgee shall also
have the right to retain the Securities and denominate the same as "treasury
shares" and the Pledgor shall continue to be liable for the difference between
the outstanding amount of Secured Obligations and the fair market value of
Collateral so denominated as "treasury shares." In this connection, and for
purposes of this Agreement, the Pledgor acknowledges and agrees that the Pledged
Collateral is of "a type customarily sold on a recognized market" within the
meaning of Section 9-504(3) of the Uniform Commercial Code in effect in the
State of Georgia (or any similar successor statue). Accordingly, the Pledgor
specifically acknowledges and agrees that retaining Securities as "treasury
shares" constitutes a "commercially reasonable " disposition of the Pledged
Collateral within the meaning of the Uniform Commercial Code and that it is
appropriate for the Pledgor to continue to be liable for, and the Pledgor agrees
to be so liable for, any deficiency between the outstanding amount of Secured
Obligations at the time of such denomination as "treasury shares" and the fair
market value of such "treasury shares."

     (d)  The rights and remedies of the Pledgee under this Agreement are
cumulative and not exclusive of any rights or remedies which it would otherwise
have.

     Section 8.  Application of Proceeds of Sale and Cash.  The proceeds of any
                 ----------------------------------------
sale of the whole or any part of the Collateral, together with any other moneys
held by the Pledgee under the provisions of this Agreement, shall be applied by
the Pledgee in the following order

     (a)  First: to the payment of all costs and expenses incurred in connection
with such sale or other realization, including reasonable attorneys' fees
incurred if the Pledgee endeavored to collect the Secured Obligations by or
through an attorney at law;

     (b)  Second: to the payment of the interest due upon any of the Secured
Obligations, in any order which the Pledgee may elect;

     (c)  Third: to the payment of the principal due upon any of the Secured
Obligations in any order which the Pledgee may elect; and

     (d)  Fourth: the balance (if any) of such proceeds shall be paid to the
Pledgor or to whomsoever may be legally entitled thereto.

The Pledgor shall remain liable and will pay, on demand, any deficiency
remaining in respect of the Secured Obligations.

     Section 9.  Pledgee Appointed Attorney-in-Fact.  The Pledgor hereby
                 ----------------------------------
constitutes and appoints the Pledgee as the attorney-in-fact of the Pledgor with
full power of substitution either in the Pledgee's name or in the name of the
Pledgor to carry out the

                                      -6-
<PAGE>

provisions of this Agreement and to take any action and execute any instrument
which the Pledgee may deem necessary or advisable to accomplish the purposes
hereof, and to do all acts and things and execute all documents in the name of
the Pledgor or otherwise, deemed by the Pledgee as necessary, proper and
convenient in connection with the preservation, perfection or enforcement of its
rights hereunder. Nothing herein contained shall be construed as requiring or
obligating the Pledgee to make any commitment or to make any inquiry as to the
nature or sufficiency of any payment received by it, or to present or file any
claim or notice, or to take any action with respect to the Collateral or any
part thereof or the moneys due or to become due in respect thereof or any
property covered thereby, and no action taken by the Pledgee or omitted to be
taken with respect to the Collateral or any part thereof shall give rise to any
defense, counterclaim or offset in favor of the Pledgor or to any claim or
action against the Pledgee. The power or attorney granted herein is irrevocable
and coupled with an interest.

     Section 10. Further Assurances.  The Pledgor shall, at its sole cost and
                 ------------------
expense, take all action that may be reasonably necessary or desirable in the
Pledgee's sole discretion, so as at all times to maintain the validity,
perfection, enforceability and priority of the Pledgee's security interest in
the Collateral, or to enable the Pledgee to exercise or enforce its rights
hereunder.  The Pledgor agrees to take, and authorizes the Pledgee to take on
the Pledgor's behalf, any or all of the following actions with respect to any
Collateral as the Pledgee shall deem necessary to perfect the security interest
and pledge created hereby or to enable the Pledgee to enforce its rights and
remedies hereunder: (i) to register in the name of the Pledgee any Collateral in
certificated or uncertificated form; (ii) to endorse in the name of the Pledgee
any Collateral issued in certificated form; and (iii) by book entry or
otherwise, identify as belonging to the Pledgee a quantity of securities that
constitutes all or part of the Collateral registered in the name of the Pledgee.
Notwithstanding the foregoing the Pledgor agrees that Collateral which is not in
certificated form or is otherwise in book-entry form shall be held for the
account of the Pledgee.  The Pledgor hereby authorizes the Pledgee to execute
and file in all necessary and appropriate jurisdictions (as determined by the
Pledgee) one or more financing or continuation statements in the name of the
Pledgor and to sign the Pledgor's name thereto.  The Pledgor authorizes the
Pledgee to file any such financing statement, document or instrument without the
signature of the Pledgor to the extent permitted by applicable law.  To the
extent permitted by applicable law, a carbon, photographic, xerographic or other
reproduction of this Agreement or any financing statement is sufficient as a
financing statement.  Any property comprising part of the Collateral required to
be delivered to the Pledgee pursuant to this Pledge Agreement shall be
accompanied by proper instruments of assignment duly executed by the Pledgor and
by such other instruments or documents as the Pledgee may reasonably request.

     Section 11. Securities Act.  In view of the position of the Pledgor in
                 --------------
relation to the Collateral, or because of other current or future circumstances,
a question may arise under the Securities Act or any similar applicable law
hereafter enacted analogous in purpose or effect (such Act and any such similar
applicable law as from time to time in effect being called the "Federal
Securities Laws") with respect to any disposition of the

                                      -7-
<PAGE>

Collateral permitted hereunder. The Pledgor understands that compliance with the
Federal Securities Laws might very strictly limit the course of conduct of the
Pledgee if the Pledgee were to attempt to dispose of all or any part of the
Collateral in accordance with the terms hereof, and might also limit the extent
to which or the manner in which any subsequent transferee of any Collateral
could dispose of the same. Similarly, there may be other legal restrictions or
limitations affecting the Pledgee in any attempt to dispose of all or part of
the Collateral in accordance with the terms hereof under applicable Blue Sky or
other state securities laws or similar applicable law analogous in purpose or
effect. The Pledgor recognizes that in light of the foregoing restrictions and
limitations the Pledgee may, with respect to any sale of the Collateral, limit
the purchasers to those who will agree, among other things, to acquire such
Collateral for their own account, for investment, and not with a view to the
distribution or resale thereof. The Pledgor acknowledges and agrees that in
light of the foregoing restrictions and limitations, the Pledgee, in its sole
and absolute discretion, may, in accordance with applicable law, (a) proceed to
make such a sale whether or not a registration statement for the purpose of
registering such Collateral or part thereof shall have been filed under the
Federal Securities Laws and (b) approach and negotiate with a single potential
purchaser to effect such sale. The Pledgor acknowledges and agrees that any such
sale might result in prices and other terms less favorable to the seller than if
such sale were a public sale without such restrictions. In the event of any such
sale, the Pledgee shall incur no responsibility or liability for selling all or
any part of the Collateral in accordance with the terms hereof at a price that
the Pledgee, in its sole and absolute discretion, may in good faith deem
reasonable under the circumstances, notwithstanding the possibility that a
substantially higher price might have been realized if the sale were deferred
until after registration as aforesaid or if more than a single purchaser were
approached. The provisions of this Section will apply notwithstanding the
existence of a public or private market upon which the quotations or sales
prices may exceed substantially the price at which the Pledgee sells.

     Section 12. Indemnification.  The Pledgor agrees to indemnify and hold the
                 ---------------
Pledgee and any corporation controlling, controlled by, or under common control
with, the Pledgee and any officer, attorney, director, shareholder, agent or
employee of the Pledgee or any such corporation (each an "Indemnified Person"),
harmless from and against any claim, loss, damage, action, cause of action,
liability, cost and expense or suit of any kind or nature whatsoever
(collectively, "Losses"), brought against or incurred by an Indemnified Person,
in any manner arising out of or, directly or indirectly, related to or connected
with this Agreement, including without limitation, the exercise by the Pledgee
of any of its rights and remedies under this Agreement or any other action taken
by the Pledgee pursuant to the terms of this Agreement; provided, however, the
                                                        --------  -------
Pledgor shall not be liable to an Indemnified Person for any Losses to the
extent that such Losses result from the gross negligence or willful misconduct
of such Indemnified Person.  The Pledgor's obligations under this section shall
survive the termination of this Agreement and the payment in full of the Secured
Obligations.

                                      -8-
<PAGE>

     Section 13. Continuing Security Interest.  This Agreement shall create a
                 ----------------------------
continuing security interest in the Collateral and shall remain in full force
and effect until it terminates in accordance with its terms.  The Pledgor and
the Pledgee hereby agree that the security interest created by this Agreement in
the Collateral shall not terminate and shall continue and remain in full force
and effect notwithstanding the transfer to the Pledgor or any person designated
by it of all or any portion of the Collateral.

     Section 14. No Waiver.  Neither the failure on the part of the Pledgee to
                 ---------
exercise, nor the delay on its part in exercising any right, power or remedy
hereunder, nor any course of dealing between the Pledgee and the Pledgor shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such right, power, or remedy hereunder preclude any other or the further
exercise thereof or the exercise of any other right, power or remedy.

     Section 15. Notices.  Notices, requests and other communications required
                 -------
or permitted hereunder shall be given in accordance with the applicable terms of
the Note.

     SECTION 16. GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY, AND
                 -------------
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF GEORGIA.

     Section 17. Amendments.  No amendment or waiver of any provision of this
                 ----------
Agreement nor consent to any departure by the Pledgor herefrom shall in any
event be effective unless the same shall be in writing and signed by the parties
hereto, and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given.

     Section 18. Binding Agreement; Assignment.  This Agreement shall be
                 -----------------------------
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns, except that the Pledgor shall not be permitted to assign
this Agreement or any interest herein or in the Collateral, or any part thereof,
or any cash or property held by the Pledgee as collateral under this Agreement.

     Section 19. Termination.  Upon indefeasible payment in full of all of the
                 -----------
Secured Obligations, this Agreement shall terminate.  Upon termination of this
Agreement in accordance with its terms the Pledgee agrees to take such actions
as the Pledgor may reasonably request, and at the sole cost and expense of the
Pledgor, (a) to return the Collateral to the Pledgor, and (b) to evidence the
termination of this Agreement, including, without limitation, the filing of any
releases or any termination statements under the Uniform Commercial Code.

     Section 20. Severability.  Whenever possible, each provision of this
                 ------------
Agreement shall be interpreted in such a manner as to be effective and valid
under applicable law, but if any provision of this Agreement shall be prohibited
by or invalid under applicable law, such provisions shall be ineffective only to
the extent of such prohibition or invalidity,

                                      -9-
<PAGE>

without invalidating the remainder of such provisions or the remaining
provisions of this Agreement.

     Section 21. Headings.  Section headings used herein are for convenience
                 --------

                             EMPLOYMENT AGREEMENT

     THIS EMPLOYMENT AGREEMENT (this "Agreement") is made and entered into this
____ day of January, 2000  by and between National Data Corporation, a Delaware
corporation (the "Company"), and Walter M. Hoff ("Executive"), to be effective
as of the Effective Date, as defined in Section 1.

                                  BACKGROUND
                                  ----------

     Executive currently serves as the President and Chief Executive Officer of
NDC Health Information Services, a line of business of the Company.  Executive
and the Company desire to memorialize the terms of such employment in this
Agreement.  In addition, the Board of Directors of the Company (the "Board"),
has determined that it is in the best interests of the Company and its
stockholders to assure that the Company will have the continued dedication of
the Executive, notwithstanding the possibility, threat or occurrence of a Change
in Control (as defined below) of the Company.  As it is desired and anticipated
that Executive will continue to be employed and provide services for the
Company's successor for at least 24 months following a Change in Control, one
purpose of this Agreement is to provide Executive with compensation and benefits
arrangements which ensure that the compensation and benefits expectations of
Executive will be satisfied and which are competitive with those of other
corporations.  Therefore, in order to accomplish these objectives, the Board has
caused the Company to enter into this Agreement.

     NOW THEREFORE, in consideration of the foregoing and of the mutual
covenants and agreements set forth herein, and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:

     1.   Effective Date.  The effective date of this Agreement (the "Effective
          --------------
Date") is December 1, 1999.

     2.   Employment.  Executive is hereby employed as the President and Chief
          ----------
Executive Officer of NDC Health Information Services, a line of business of the
Company.  In such capacity, Executive shall have the responsibilities outlined
on Exhibit A to this Agreement and such other responsibilities commensurate with
such position as shall be assigned to him by the Chief Executive Officer of the
Company, in accordance with the policies and objectives established by the
Board.

     3.   Employment Period.  Executive's employment hereunder shall begin on
          -----------------
the Effective Date and continue until terminated in accordance with Section 7
hereof (the "Employment Period").

     4.   Extent of Service.  During the Employment Period, Executive shall
          -----------------
render his services to the Company (or to its successor following a Change in
Control) in conformity with professional standards, in a prudent and workmanlike
manner and in a manner
<PAGE>

consistent with the obligations imposed on officers of corporations under
applicable law. Executive shall promote the interests of the Company and its
subsidiaries in carrying out Executive's duties and shall not deliberately take
any action which could, or fail to take any action which failure could,
reasonably be expected to have a material adverse effect upon the business of
the Company or any of its subsidiaries or any of their respective affiliates.
Executive agrees to devote his business time, attention, skill and efforts
exclusively to the faithful performance of his duties hereunder (both before and
after a Change in Control); provided, however, that it shall not be a violation
of this Agreement for Executive to (i) devote reasonable periods of time to
charitable and community activities and, with the approval of the Company,
industry or professional activities, and/or (ii) manage personal business
interests and investments, so long as such activities do not materially
interfere with the performance of Executive's responsibilities under this
Agreement. It is expressly understood and agreed that to the extent that any
such activities have been conducted by Executive prior to the date of this
Agreement (as to which activities Executive shall have given written notice to
the Company prior to the Effective Date), the continued conduct of such
activities subsequent to the Effective Date shall not thereafter be deemed to
interfere with the performance of Executive's responsibilities hereunder.

     5.   Compensation and Benefits.
          -------------------------

          (a)  Base Salary. Thereafter, during the Employment Period, the
               -----------
Company will pay to Executive a base salary in the amount of U.S. $400,000 per
year ("Base Salary"), less normal withholdings, payable in equal bi-weekly or
other installments as are customary under the Company's payroll practices from
time to time. The Compensation Committee of the Board shall review Executive's
Base Salary periodically and in its sole discretion, subject to approval of the
Board, may increase Executive's Base Salary from time to time. The periodic
review of Executive's salary by the Board will consider, among other things,
Executive's own performance and the Company's performance.

          (b)  Incentive and Savings Plans.  During the Employment Period,
               ---------------------------
Executive shall be entitled to participate in incentive and savings plans,
practices, policies and programs applicable generally to employees of the
Company.  Certain executive programs will be made available on a selective basis
at the discretion of the Chief Executive Officer or the Compensation Committee
of the Board.  Without limiting the foregoing, the following shall apply:

               (i)  Annual Bonus.  Executive will have an annual bonus
                    ------------
opportunity of not less than $400,000, based on 100% achievement of agreed-upon
financial objectives ("Bonus Opportunity"). The Company may determine in any
year that a portion of the Bonus Opportunity for that year will be deferred
based upon sustained results over time. The annual Bonus Opportunity and
specific performance objectives will be set forth in Executive's individual
performance and incentive plan for each year.

                                      -2-
<PAGE>

               (ii) Incentive Awards.  On or about the Effective Date (or
                    ----------------
earlier upon Executive's hire date), the Company made a grant of restricted
stock and/or stock options to Executive as a long-term incentive for performance
and in consideration for entering into this Agreement. Further grants of
incentive awards may be made to Executive in future years.

          (c)  Welfare Benefit Plans.  During the Employment Period, Executive
               ---------------------
and Executive's family shall be eligible for participation in, and shall receive
all benefits under, the welfare benefit plans, practices, policies and programs
provided by the Company (including, without limitation, medical, prescription,
dental, disability, employee life, group life, accidental death and travel
accident insurance plans and programs) ("Welfare Plans").

          (d)  Expenses.  During the Employment Period, Executive shall be
               --------
entitled to receive prompt reimbursement for all reasonable expenses incurred by
Executive in accordance with the policies, practices and procedures of the
Company.

          (e)  Fringe Benefits.  During the Employment Period, Executive shall
               ---------------
be entitled to fringe benefits in accordance with the plans, practices, programs
and policies of the Company.

     6.   Change in Control.  For the purposes of this Agreement, a "Change in
          -----------------
Control" shall mean:

          (a)  The acquisition by any individual, entity or group (within the
meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934,
as amended (the "Exchange Act")) (a "Person") of beneficial ownership (within
the meaning of Rule 13d-3 promulgated under the Exchange Act) of 35% or more of
the combined voting power of the then outstanding voting securities of the
Company entitled to vote generally in the election of directors (the
"Outstanding Company Voting Securities"); provided, however, that for purposes
of this subsection (a), the following acquisitions shall not constitute a Change
in Control: (i) any acquisition by a Person who is on the Effective Date the
beneficial owner of 35% or more of the Outstanding Company Voting Securities,
(ii) any acquisition directly from the Company, (iii) any acquisition by the
Company which reduces the number of Outstanding Company Voting Securities and
thereby results in any person having beneficial ownership of more than 35% of
the Outstanding Company Voting Securities, (iv) any acquisition by any employee
benefit plan (or related trust) sponsored or maintained by the Company or any
corporation controlled by the Company, or (v) any acquisition by any corporation
pursuant to a transaction which complies with clauses (i) and (ii) of subsection
(b) of this Section 6; or

          (b)  Consummation of a reorganization, merger or consolidation or sale
or other disposition of all or substantially all of the assets of the Company (a
"Business Combination"), in each case, unless, following such Business
Combination, (i) all or substantially all of the individuals and entities who
were the beneficial owners,

                                      -3-
<PAGE>

respectively, of the Outstanding Company Common Stock and Outstanding Company
Voting Securities immediately prior to such Business Combination beneficially
own, directly or indirectly, more than 50% of, respectively, the then
outstanding shares of common stock and the combined voting power of the then
outstanding voting securities entitled to vote generally in the election of
directors, as the case may be, of the corporation resulting from such Business
Combination (including, without limitation, a corporation which as a result of
such transaction owns the Company or all or substantially all of the Company's
assets either directly or through one or more subsidiaries) in substantially the
same proportions as their ownership, immediately prior to such Business
Combination of the Outstanding Company Common Stock and Outstanding Company
Voting Securities, as the case may be, and (ii) no Person (excluding the Company
or any employee benefit plan (or related trust) of the Company or such
corporation resulting from such Business Combination) beneficially owns,
directly or indirectly, 35% or more of the combined voting power of the then
outstanding voting securities of such corporation except to the extent that such
ownership existed prior to the Business Combination; provided, however, that

          (c)  Notwithstanding anything in this definition to the contrary, a
restructuring and/or separation of any line of business or business unit from
the Company will not of itself constitute a Change in Control.

     7.   Termination of Employment.
          -------------------------

          (a)  Death, Retirement or Disability.  Executive's employment and the
               -------------------------------
Employment Period shall terminate automatically upon Executive's death or
Retirement.  For purposes of this Agreement, "Retirement" shall mean normal
retirement as defined in the Company's then-current retirement plan, or there is
no such retirement plan, "Retirement" shall mean voluntary termination after age
65 with ten years of service.  If the Company determines in good faith that the
Disability of Executive has occurred (pursuant to the definition of Disability
set forth below), it may give to Executive written notice of its intention to
terminate Executive's employment.  In such event, Executive's employment with
the Company shall terminate effective on the 30th day after receipt of such
written notice by Executive (the "Disability Effective Date"), provided that,
within the 30 days after such receipt, Executive shall not have returned to
full-time performance of Executive's duties.  For purposes of this Agreement,
"Disability" shall mean a mental or physical disability as determined by the
Board in accordance with standards and procedures similar to those under the
Company's employee long-term disability plan, if any.  At any time that the
Company does not maintain such a long-term disability plan, Disability shall
mean the inability of Executive, as determined by the Board, to substantially
perform the essential functions of his regular duties and responsibilities due
to a medically determinable physical or mental illness which has lasted (or can
reasonably be expected to last) for a period of six consecutive months.

                                      -4-
<PAGE>

          (b)  Termination by the Company.  The Company may terminate
               --------------------------
Executive's employment for Poor Performance or with or without Cause. For
purposes of this Agreement:

               "Poor Performance" shall mean the consistent failure of Executive
to meet reasonable performance expectations (other than any such failure
resulting from incapacity due to physical or mental illness); provided, however,
that termination for Poor Performance shall not be effective unless at least 30
days prior to such termination Executive shall have received written notice from
Chief Executive Officer or the Board which specifically identifies the manner in
which the Board or the Chief Executive Officer believes that Executive has not
met performance expectations and Executive shall have failed after receipt of
such notice to resume the diligent performance of his duties to the satisfaction
of the Chief Executive Officer or the Board; and

               "Cause" shall mean:

               (i)    the willful and continued failure of Executive to perform
substantially Executive's duties with the Company (other than any such failure
resulting from incapacity due to physical or mental illness, and specifically
excluding any failure by Executive, after reasonable efforts, to meet
performance expectations), after a written demand for substantial performance is
delivered to Executive by the President, Chief Executive Officer or the Board of
Directors of the Company which specifically identifies the manner in which such
Board or officer believes that Executive has not substantially performed
Executive's duties, or

               (ii)   any act of fraud, misappropriation, embezzlement or
similar dishonest or wrongful act by Executive, or

               (iii)  Executive's abuse of alcohol or any substance which
materially interferes with Executive's ability to perform services on behalf of
the Company, or

               (iv)   Executive's conviction for, or plea of guilty or nolo
contendere to, a felony.

          (c)  Termination by Executive.  Executive's employment may be
               ------------------------
terminated by Executive for Good Reason or no reason. For purposes of this
Agreement, "Good Reason" shall mean:

               (i)  without the written consent of Executive, the assignment to
Executive of any duties materially inconsistent with Executive's position
(including offices, titles and reporting requirements), authority, duties or
responsibilities as in effect on the Effective Date, or any other action by the
Company which results in a material diminution in such position, authority,
duties or responsibilities, excluding for this purpose an isolated,
insubstantial and inadvertent action not taken in bad faith and which is
remedied by the Company promptly after receipt of notice thereof given by
Executive;

               (ii)   a reduction by the Company in Executive's Base Salary and
benefits as in effect on the Effective Date or as the same may be increased from
time to time, unless a similar reduction is made in salary and benefits of
similarly-situated senior executives;

               (iii)  the Company's requiring Executive, without his consent, to
be based at any office or location other than in the greater metropolitan area
of the city in which his office is located at the Effective Date; or

               (iv)   any failure by the Company to comply with and satisfy
Section 16(c) of this Agreement.

          (d)  Notice of Termination.  Any termination by the Company for Poor
               ---------------------
Performance or Cause, or by Executive for Good Reason, shall be communicated by
Notice of Termination to the other party hereto given in accordance with Section
17(f) of this Agreement.  For purposes of this Agreement, a "Notice of
Termination" means a written notice which (i) indicates the specific termination
provision in this Agreement relied upon, (ii) to the extent applicable, sets
forth in reasonable detail the facts and circumstances claimed to provide a
basis for termination of Executive's employment under the provision so indicated
and (iii) if the Date of Termination (as defined below) is other than the date
of receipt of such notice, specifies the termination date (which date shall be
not more than 30 days after the giving of such notice).  The failure by
Executive or the Company to set forth in the Notice of Termination any fact or
circumstance which contributes to a showing of Good Reason, Poor Performance or
Cause shall not waive any right of Executive or the Company, respectively,
hereunder or preclude Executive or the Company, respectively, from asserting
such fact or circumstance in enforcing Executive's or the Company's rights
hereunder.

          (e)  Date of Termination.  "Date of Termination" means (i) if
               -------------------
Executive's employment is terminated other than by reason of death, Disability
or Retirement, the date of receipt of the Notice of Termination, or any later
date specified therein (which shall not be more than 60 days after the date of
delivery of the Notice of Termination), or (ii) if Executive's employment is
terminated by reason of death, Disability or Retirement, the Date of Termination
will be the date of death or Retirement, or the Disability Effective Date, as
the case may be.

     8.   Obligations of the Company upon Termination.

          (a)  Prior to a Change in Control: Termination by Executive for Good
               ---------------------------------------------------------------
Reason; Termination by the Company Other Than for Poor Performance, Cause or

----------
Executive's employment other than for Poor Performance, Cause or Disability, or
Executive shall terminate employment for Good Reason within a period of 90 days

described in clauses (ii) through (vii) below, only if Executive executes a

equal monthly or more frequent installments as are customary under the Company's
payroll practices from time to time; provided, however that the Company's

(prorated through the Date of Termination) adjusted up or down by reference to
his year-to-date performance at the Date of Termination in relation to the prior

provided, however that the bonus payment described in this Section 8(a)(iv)

Company; and

               (v)    all grants of restricted stock of the Company ("Restricted

Company ("Options") that would have become vested (by lapse of time) within the

during such period will become immediately vested as of the Date of Termination;
and

               (vii)  notwithstanding the provisions of the applicable Option
agreement, all of Executive's vested but unexercised Options as of the Date of
Termination (including those with accelerated vesting pursuant to Section
8(a)(vi) above) shall remain exercisable through the earlier of (A) the original
expiration date of the Option, or (B) the 90/th/ day following the end of the
Normal Severance Period; and

               (viii) to the extent not theretofore paid or provided, the
Company shall timely pay or provide to Executive any other amounts or benefits
required to be paid or provided or which Executive is eligible to receive under
any plan, program, policy or practice or contract or agreement of the Company
(such other amounts and benefits shall be hereinafter referred to as the "Other
Benefits").

          (b)  Prior to a Change in Control: Termination by the Company for Poor
               -----------------------------------------------------------------
Performance.  If, prior to the occurrence of a Change in Control, the Company
-----------
shall terminate Executive's employment for Poor Performance, then (and with
respect to the payments and benefits described in clauses (ii) through (vii)
below, only if Executive executes the Release):

               (i)    the Company shall pay to Executive the Accrued Obligations
in a lump sum in cash within 30 days after the Date of Termination; and

               (ii)   for the shorter of 12 months after the Date of Termination
or until Executive becomes employed with a subsequent employer (the "Poor
Performance Severance Period"), the Company will continue to pay Executive an
amount equal to his monthly Base Salary, payable in equal monthly or more
frequent installments as are customary under the Company's payroll practices
from time to time; provided, however that the Company's obligation to make or
continue such payments shall cease if Executive violates any of the Restrictive
Covenants (as defined in Section 13(a) of this Agreement) and fails to remedy
such violation to the satisfaction of the Board within 10 days of notice of such
violation; and

               (iii)  during the Poor Performance Severance Period, the Company
shall continue benefits to Executive and/or Executive's family at least equal to
those which would have been provided to them in accordance with the Welfare
Plans described in Section 5(c) of this Agreement if Executive's employment had
not been terminated; provided, however that the Company's obligation to provide
such benefits shall cease if Executive violates any of the Restrictive Covenants
(as defined in Section 13(a) of this Agreement) and fails to remedy such
violation to the satisfaction of the Board within 10 days of notice of such
violation; and

               (iv)   not later than 30 days after the Date of Termination,
Executive will be paid a bonus for the year in which the Date of Termination

                                      -8-
<PAGE>

equal to 100% of his Bonus Opportunity (prorated through the Date of
Termination) adjusted up or down by reference to his year-to-date performance at
the Date of Termination in relation to the prior established performance
objectives under Executive's bonus plan for such year; provided, however that

               (v)    all grants of Restricted Stock held by Executive as of the

Termination; and

               (vi)   all of Executive's Options that would have become vested
(by lapse of time) within the 24-month period following the Date of Termination

               ---------------------------------------------------------------
Executive for Good Reason; Termination by the Company Other Than for Cause or
-----------------------------------------------------------------------------
Disability.  If there occurs a Change in Control and, within 36 months following
----------
such Change in Control (or if Executive can reasonably show that such
termination by the Company was in anticipation of the Change in Control), the
Company shall terminate Executive's employment other than for Cause or
Disability, or Executive shall terminate employment for Good Reason, then (and
with respect to the payments and benefits described in clauses (ii) through
(vii) below, only if Executive executes the Release):

               (i)   the Company (or its successor) shall pay to Executive the

the Company's payroll

                                      -9-
<PAGE>

practices from time to time; provided, however that the Company's obligation to
make or continue such payments shall cease if Executive violates any of the
Restrictive Covenants (as defined in Section 13(a) of this Agreement) and fails
to remedy such violation to the satisfaction of the Board within 10 days of
notice of such violation; and

               (iii)  during the Change in Control Severance Period, the Company
shall continue benefits to Executive and/or Executive's family at least equal to
those which would have been provided to them in accordance with the Welfare
Plans described in Section 5(c) of this Agreement if Executive's employment had
not been terminated; provided, however that the Company's obligation to provide
such benefits shall cease if Executive violates any of the Restrictive Covenants
(as defined in Section 13(a) of this Agreement) and fails to remedy such
violation to the satisfaction of the Board within 10 days of notice of such
violation; and

               (iv)   not later than 30 days after the Date of Termination,
Executive will be paid a bonus for the year in which the Date of Termination

agreement, all of Executive's vested but unexercised Options as of the Date of
Termination (including those with accelerated vesting pursuant to the Section

          (d)  Death, Disability or Retirement.  Regardless of whether or not a
               -------------------------------
Change in Control shall have occurred, if Executive's employment is terminated
by reason of Executive's death, Disability or Retirement, this Agreement shall
terminate without further obligations to Executive or his estate or legal
representatives under this Agreement, other than for payment of Accrued
Obligations and the timely payment or provision of Other Benefits.  Accrued
Obligations shall be paid to Executive's estate or beneficiary, as applicable,
in a lump sum in cash within 30 days of the Date of

                                     -10-
<PAGE>

Termination. With respect to the provision of Other Benefits, the term Other
Benefits as used in this Section 8(d) shall include, without limitation, and
Executive or his estate and/or beneficiaries shall be entitled to receive,
benefits under such plans, programs, practices and policies relating to death,
disability or retirement benefits, if any, as are applicable to Executive on the
Date of Termination.

          (e)  Cause or Voluntary Termination without Good Reason.  Regardless
               --------------------------------------------------
of whether or not a Change in Control shall have occurred, if Executive's
employment shall be terminated for Cause, or if Executive voluntarily terminates
employment without Good Reason, this Agreement shall terminate without further
obligations to Executive, other than for payment of Accrued Obligations and the
timely payment or provision of Other Benefits.

     9.   Non-exclusivity of Rights.  Nothing in this Agreement shall prevent or
          -------------------------
limit Executive's continuing or future participation in any plan, program,
policy or practice provided by the Company and for which Executive may qualify,
nor, subject to Section 17(d), shall anything herein limit or otherwise affect
such rights as Executive may have under any contract or agreement with the
Company.  Amounts which are vested benefits or which Executive is otherwise
entitled to receive under any plan, policy, practice or program of or any
contract or agreement with the Company at or subsequent to the Date of
Termination shall be payable in accordance with such plan, policy, practice or
program or contract or agreement except as explicitly modified by this
Agreement.

     10.  Certain Additional Payments by the Company.
          ------------------------------------------

          (a)  Anything in this Agreement to the contrary notwithstanding and
except as set forth below, in the event it shall be determined that any payment
or distribution by the Company to or for the benefit of Executive (whether paid
or payable or distributed or distributable pursuant to the terms of this
Agreement or otherwise, but determined without regard to any additional payments
required under this Section 10) (a "Payment") would be subject to the excise tax
imposed by Section 4999 of the Code or any interest or penalties are incurred by
Executive with respect to such excise tax (such excise tax, together with any
such interest and penalties, are hereinafter collectively referred to as the
"Excise Tax"), then Executive shall be entitled to receive an additional payment
(a "Gross-Up Payment") in an amount such that after payment by Executive of all
taxes (including any interest or penalties imposed with respect to such taxes),
including, without limitation, any income taxes (and any interest and penalties
imposed with respect thereto) and Excise Tax imposed upon the Gross-Up Payment,
Executive retains an amount of the Gross-Up Payment equal to the Excise Tax
imposed upon the Payments.  Notwithstanding the foregoing provisions of this
Section 10(a), if it shall be determined that Executive is entitled to a Gross-
Up Payment, but that Executive, after taking into account the Payments and the
Gross-Up Payment, would not receive a net after-tax benefit of at least $50,000
(taking into account both income taxes and any Excise Tax) as compared to the
net after-tax proceeds to Executive resulting from an elimination of the Gross-
Up Payment and a reduction of the Payments, in the aggregate, to an amount (the

                                     -11-
<PAGE>

"Reduced Amount") such that the receipt of Payments would not give rise to any
Excise Tax, then no Gross-Up Payment shall be made to Executive and the
Payments, in the aggregate, shall be reduced to the Reduced Amount.  In that
event, Executive shall direct which Payments are to be modified or reduced.

          (b)  Subject to the provisions of Section 10(c), all determinations
required to be made under this Section 10, including whether and when a Gross-Up
Payment is required and the amount of such Gross-Up Payment and the assumptions
to be utilized in arriving at such determination, shall be made by Arthur
Andersen LLP or such other certified public accounting firm reasonably
acceptable to the Company as may be designated by Executive (the "Accounting
Firm") which shall provide detailed supporting calculations both to the Company
and Executive within 15 business days of the receipt of notice from Executive
that there has been a Payment, or such earlier time as is requested by the
Company.  In the event that the Accounting Firm is serving as accountant or
auditor for the individual, entity or group effecting the Change in Control,
Executive shall appoint another nationally recognized accounting firm to make
the determinations required hereunder (which accounting firm shall then be
referred to as the Accounting Firm hereunder).  All fees and expenses of the
Accounting Firm shall be borne solely by the Company.  Any Gross-Up Payment, as
determined pursuant to this Section 10, shall be paid by the Company to
Executive within five days of the receipt of the Accounting Firm's
determination.  Any determination by the Accounting Firm shall be binding upon
the Company and Executive.  As a result of the uncertainty in the application of
Section 4999 of the Code at the time of the initial determination by the
Accounting Firm hereunder, it is possible that Gross-Up Payments which will not
have been made by the Company should have been made ("Underpayment"), consistent
with the calculations required to be made hereunder.  In the event that the
Company exhausts its remedies pursuant to Section 10(c) and Executive thereafter
is required to make a payment of any Excise Tax, the Accounting Firm shall
determine the amount of the Underpayment that has occurred and any such
Underpayment shall be promptly paid by the Company to or for the benefit of
Executive.

          (c)  The Executive shall notify the Company in writing of any claim by
the Internal Revenue Service that, if successful, would require the payment by
the Company of the Gross-Up Payment.  Such notification shall be given as soon
as practicable but no later than ten business days after Executive is informed
in writing of such claim and shall apprise the Company of the nature of such
claim and the date on which such claim is requested to be paid.  The Executive
shall not pay such claim prior to the expiration of the 30-day period following
the date on which it gives such notice to the Company (or such shorter period
ending on the date that any payment of taxes with respect to such claim is due).
If the Company notifies Executive in writing prior to the expiration of such
period that it desires to contest such claim, Executive shall:

               (i)  give the Company any information reasonably requested by the
Company relating to such claim,

                                     -12-
<PAGE>

               (ii)   take such action in connection with contesting such claim
as the Company shall reasonably request in writing from time to time, including,
without limitation, accepting legal representation with respect to such claim by
an attorney reasonably selected by the Company,

               (iii)  cooperate with the Company in good faith in order
effectively to contest such claim, and

               (iv)   permit the Company to participate in any proceedings
relating to such claim;

provided, however, that the Company shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify and hold Executive harmless, on an after-
tax basis, for any Excise Tax or income tax (including interest and penalties
with respect thereto) imposed as a result of such representation and payment of
costs and expenses.  Without limitation of the foregoing provisions of this
Section 10(c), the Company shall control all proceedings taken in connection
with such contest and, at its sole option, may pursue or forgo any and all
administrative appeals, proceedings, hearings and conferences with the taxing
authority in respect of such claim and may, at its sole option, either direct
Executive to pay the tax claimed and sue for a refund or contest the claim in
any permissible manner, and Executive agrees to prosecute such contest to a
determination before any administrative tribunal, in a court of initial
jurisdiction and in one or more appellate courts, as the Company shall
determine; provided, however, that if the Company directs Executive to pay such
claim and sue for a refund, the Company shall advance the amount of such payment
to Executive, on an interest-free basis and shall indemnify and hold Executive
harmless, on an after-tax basis, from any Excise Tax or income tax (including
interest or penalties with respect thereto) imposed with respect to such advance
or with respect to any imputed income with respect to such advance; and further
provided that any extension of the statute of limitations relating to payment of
taxes for the taxable year of Executive with respect to which such contested
amount is claimed to be due is limited solely to such contested amount.
Furthermore, the Company's control of the contest shall be limited to issues
with respect to which a Gross-Up Payment would be payable hereunder and
Executive shall be entitled to settle or contest, as the case may be, any other
issue raised by the Internal Revenue Service or any other taxing authority.

          (d)  If, after the receipt by Executive of an amount advanced by the
Company pursuant to Section 10(c), Executive becomes entitled to receive any
refund with respect to such claim, Executive shall (subject to the Company's
complying with the requirements of Section 10(c)) promptly pay to the Company
the amount of such refund (together with any interest paid or credited thereon
after taxes applicable thereto).  If, after the receipt by Executive of an
amount advanced by the Company pursuant to Section 10(c), a determination is
made that Executive shall not be entitled to any refund with respect to such
claim and the Company does not notify Executive in writing of its intent to
contest such denial of refund prior to the expiration of 30 days after such

                                     -13-
<PAGE>

determination, then such advance shall be forgiven and shall not be required to
be repaid and the amount of such advance shall offset, to the extent thereof,
the amount of Gross-Up Payment required to be paid.

     11.  Costs of Enforcement.  Unless otherwise provided by the arbitrator(s)
          --------------------
in an arbitration proceeding pursuant to Section 14 hereof, in any action taken
in good faith relating to the enforcement of this Agreement or any provision
herein, Executive shall be entitled to be paid any and all costs and expenses
incurred by him in enforcing or establishing his rights thereunder, including,
without limitation, reasonable attorneys' fees, whether suit be brought or not,
and whether or not incurred in trial, bankruptcy or appellate proceedings, but
only if Executive is successful on at least one material issue raised in the
enforcement proceeding.

     12.  Representations and Warranties.  Executive hereby represents and
          ------------------------------
warrants to the Company that Executive is not a party to, or otherwise subject
to, any covenant not to compete with any person or entity, and Executive's
execution of this Agreement and performance of his obligations hereunder will
not violate the terms or conditions of any contract or obligation, written or
oral, between Executive and any other person or entity.

     13.  Restrictions on Conduct of Executive.
          ------------------------------------

          (a)  General.  Executive and the Company understand and agree that the
               -------
purpose of the provisions of this Section 13 is to protect legitimate business
interests of the Company, as more fully described below, and is not intended to
eliminate Executive's post-employment competition with the Company per se, nor

is it intended to impair or infringe upon Executive's right to work, earn a
living, or acquire and possess property from the fruits of his labor.  Executive
hereby acknowledges that the post-employment restrictions set forth in this
Section 13 are reasonable and that they do not, and will not, unduly impair his
ability to earn a living after the termination of this Agreement.  Therefore,
subject to the limitations of reasonableness imposed by law, Executive shall be
subject to the restrictions set forth in this Section 13.

               (i)  Restriction on Disclosure and Use of Confidential
                    -------------------------------------------------
Information and Trade Secrets.  Executive understands and agrees that the
-----------------------------
Confidential Information and Trade Secrets constitute valuable assets of the
Company and its affiliated entities, and may not be converted to Executive's own
use. Accordingly, Executive hereby agrees that Executive shall not, directly or
indirectly, at any time during the Restricted Period reveal, divulge, or
disclose to any Person not expressly authorized by the Company any Confidential
Information, and Executive shall not, directly or indirectly, at any time during
the Restricted Period use or make use of any Confidential Information in
connection with any business activity other than that of the Company. Throughout
the term of this Agreement and at all times after the date that this Agreement
terminates for any reason, Executive shall not directly or indirectly transmit
or disclose any Trade Secret of the Company to any Person, and shall not make
use of any such Trade Secret, directly or indirectly, for himself or for others,
without the prior written consent of the Company. The parties acknowledge and
agree that this Agreement is not intended to, and does not, alter either the
Company's rights or Executive's obligations under any state or federal statutory
or common law regarding trade secrets and unfair trade practices.

               Anything herein to the contrary notwithstanding, Executive shall
not be restricted from disclosing or using Confidential Information that is
required to be disclosed by law, court order or other legal process; provided,
however, that in the event

                                     -16-
<PAGE>

disclosure is required by law, Executive shall provide the Company with prompt
notice of such requirement so that the Company may seek an appropriate
protective order prior to any such required disclosure by Executive.

               (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 terminate his or her
employment relationship with the Company or to enter into employment with any
other Person.

               (iii)  Restriction on Relationships with Protected Customers.
                      -----------------------------------------------------
Executive understands and agrees that the relationship between the Company and
each of its Protected Customers 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, without the
prior written consent of the Company, directly or indirectly, on Executive's own
behalf or as a Principal or Representative of any Person, solicit, divert, take
away or attempt to solicit, divert or take away a Protected Customer for the
purpose of providing or selling Competitive Services; provided, however, that
the prohibition of this covenant shall apply only to Protected Customers with
whom Executive had Material Contact on the Company's behalf during the twelve
(12) months immediately preceding the termination of his employment hereunder.
For purposes of this Agreement, Executive had "Material Contact" with a
Protected Customer if (a) he had business dealings with the Protected Customer
on the Company's behalf; (b) he was responsible for supervising or coordinating
the dealings between the Company and the Protected Customer; or (c) he obtained
Trade Secrets or Confidential Information about the customer as a result of his
association with the Company.

               (iv)   Noncompetition with the Company.  The parties
                      -------------------------------
acknowledge: (A) that Executive's services under this Agreement require special
expertise and talent in the provision of Competitive Services and that Executive
will have substantial contacts with customers, suppliers, advertisers and
vendors of the Company; (B) that pursuant to this Agreement, Executive will be
placed in a position of trust and responsibility and he will have access to a
substantial amount of Confidential Information and Trade Secrets and that the
Company is placing him in such position and giving him access to such
information in reliance upon his agreement not to compete with the Company
during the Restricted Period; (C) that due to his management duties, Executive
will be the repository of a substantial portion of the goodwill of the Company
and would have an unfair advantage in competing with the Company; (D) that due
to Executive's special experience and talent, the loss of Executive's services
to the Company under this Agreement cannot reasonably or adequately be
compensated solely by damages in an action at law; (E) that Executive is capable
of competing with the Company; and (F) that Executive is capable of obtaining
gainful, lucrative and desirable employment that does not violate the

                                     -17-
<PAGE>

restrictions contained in this Agreement.  In consideration of the compensation
and benefits being paid and to be paid by the Company to Executive hereunder,
Executive hereby agrees that, during the Restricted Period, Executive will not,
without prior written consent of the Company, directly or indirectly seek or
obtain a Competitive Position in the Restricted Territory with a Competitor;
provided, however, that the provisions of this Agreement shall not be deemed to
prohibit the ownership by Executive of any securities of the Company or its
affiliated entities or not more than five percent (5%) of any class of
securities of any corporation having a class of securities registered pursuant
to the Securities Exchange Act of 1934, as amended.

        (d)    Enforcement of Restrictive Covenants.
               ------------------------------------

               (i)  Rights and Remedies Upon Breach.  In the event Executive
                    -------------------------------
breaches, or threatens to commit a breach of, any of the provisions of the
Restrictive Covenants, the Company shall have the following rights and remedies,
which shall be independent of any others and severally enforceable, and shall be
in addition to, and not in lieu of, any other rights and remedies available to
the Company at law or in equity:

                    (A)  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; and

                    (B)  the right and remedy to require Executive to account
for and pay over to the Company all compensation, profits, monies, accruals,
increments or other benefits derived or received by Executive as the result of
any transactions constituting a breach of the Restrictive Covenants.

               (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.

                                     -18-

     14.  Arbitration.  Any claim or dispute arising under this Agreement (other
          -----------
than under Section 13) shall be subject to arbitration, and prior to commencing
any court action, the parties agree that they shall arbitrate all such
controversies.  The arbitration shall be conducted in Atlanta, Georgia, in
accordance with the Employment Dispute Rules of the American Arbitration
Association and the Federal Arbitration Act, 9 U.S.C. (S)1, et. seq.  The
arbitrator(s) shall be authorized to award both liquidated and actual damages,
in addition to injunctive relief, but no punitive damages.  The arbitrator(s)
may also award attorney's fees and costs, without regard to any restriction on
the amount of such award under Georgia or other applicable law.  Such an award
shall be binding and conclusive upon the parties hereto, subject to 9 U.S.C.
(S)10.  Each party shall have the right to have the award made the judgment of a
court of competent jurisdiction.

     Initials of parties as to this Section 14:
     Company (by R.A.Y.):     _________
     Executive:               _________

     15.  Letter of Credit.  In order to ensure the payment of the severance
          ----------------
benefit provided for in Section 8(c)(ii) of this Agreement, immediately
following the commencement of any action by a third party with the aim of
effecting a Change in Control of the Company, or the publicly-announced threat
by a third party to commence any such action, the Company shall establish an
irrevocable standby Letter of Credit issued by a national banking association in
favor of Executive in the amount of the severance payment that would have been
paid to Executive under Section 8(c)(ii) if the Date of Termination had occurred
on the date of commencement, or publicly-announced threat of commencement, of
such action by the third party.  Such Letter of Credit shall provide that the
issuer thereof, subject only to Executive's written certification to such issuer
that Executive is entitled to payment of the severance benefit pursuant to
Section 8(c)(ii) of this Agreement and that the Company shall have failed to
commence payment of such benefit to Executive, shall have the unconditional
obligation to pay the amount of such Letter of Credit to Executive in 24 equal
monthly installments commencing on the first day of the month following the Date
of Termination.  In the event that subsequent to commencement of such
installment payments to Executive pursuant to such Letter of Credit (i) the
Company and Executive shall mutually agree that Executive shall not have been
entitled to payment of the severance benefit pursuant to Section 8(c)(ii) of
this Agreement or (ii) a court of competent jurisdiction shall finally adjudge
Executive not to have been entitled to payment of such severance benefit and
such judgment shall have been affirmed on appeal or shall not have been appealed
within any time period specified for the filing of an appeal, Executive shall
promptly pay to the Company the total amount previously paid to Executive by the
issuer of such Letter of Credit and no further payment shall be made to
Executive pursuant to such Letter of Credit.

               ------

term or condition or of any other term or condition of this Agreement, unless
such waiver is contained in a writing signed by the party making the waiver.

          (b)  Severability.  If any provision or covenant, or any part thereof,
               ------------
of this Agreement should be held by any court to be invalid, illegal or
unenforceable, either in whole or in part, such invalidity, illegality or
unenforceability shall not affect the validity, legality or enforceability of
the remaining provisions or covenants, or any part thereof, of this Agreement,
all of which shall remain in full force and effect.

          (c)  Other Agents.  Nothing in this Agreement is to be interpreted as

limiting the Company from employing other personnel on such terms and conditions
as may be satisfactory to it.
