of the subsidiaries or affiliates of either (hereinafter collectively referred
to as "the Company") disclosing confidential and proprietary information, as
more fully described in section (c) below, after the date hereof, the award of
Restricted Stock, and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Participant and the Company agree
as follows:

     (a) While Participant is employed by the Company, Participant will devote
his or her entire time, energy and skills to the service of the Company. Such
employment shall be at the pleasure of the board of directors of each employing
corporation.


                                                                               3

<PAGE>

     (b) Participant will not, during the term of his or her employment with the
Company, or for a period of two years after termination for any reason of his or
her employment with the Company, directly or indirectly, either individually or
as a stockholder, director, officer, consultant, independent contractor,
employee, agent, member or otherwise of or through any corporation, partnership,
association, joint venture, firm, individual or otherwise (hereinafter "Firm"),
or in any other capacity:

          (i) Carry or engage in a business that competes with the business of
     the Company within 100 miles of any city where Participant engaged in
     business, Participant had responsibility, other employees that were
     supervised by Participant worked, or Participant otherwise conducted
     business for the Company;

          (ii) With respect to any product or service offered by or available
     from the Company, solicit, directly or indirectly, or do business with any
     customer of the Company called on, serviced by, or contacted by the
     Participant in any capacity, or otherwise known to the Participant by
     virtue of the Participant's employment with the Company in any state in
     which the Participant was employed by the Company or any state in which the
     customer does business; or

          (iii) Solicit, directly or indirectly, any employee of the Company to
     leave their employment with the Company for any reason. For purposes of
     this Agreement, the Company and Participant agree that Participant shall be
     presumed to have solicited an employee in violation of this Agreement if
     such employee is hired by Participant or his or her Firm within six (6)
     months of Participant's last employment date with the Company.

     (c) The Company shall provide confidential information to Participant and,
Participant agrees, during the term of his or her employment and thereafter, not
to use, divulge, or furnish or make accessible to any third party, company,
corporation or other organization (including, but not limited to, customers,
competitors or governmental agencies), without the Company's prior written
consent, any trade secrets, customer lists, information regarding customers,
information regarding Compass' relationships with specific existing or
prospective customers, customer goodwill associated with Compass' trade name, or
other valuable confidential and proprietary information concerning the Company
or its business, including without limitation, confidential methods of operation
and organization, trade secrets, confidential matters related to pricing,
markups, commissions and customer lists. Participant warrants and agrees that
every customer which Participant services in any way while employed at the
Company is a customer of the Company and not a customer of Participant,
individually. Participant agrees that such information remains confidential even
if committed to Participant's memory.

     (d) Participant agrees that the restrictions contained in this Section 5
are necessary and reasonable for the protection of the legitimate business
interests and goodwill of the Company described above, and Participant agrees
that any breach of this Section 5 will cause the Company substantial and
irrevocable damage and, therefore, the Company shall have the right, in addition
to any other remedies it may have, to seek specific performance and injunctive
relief, without the need to post a bond or other security. Participant agrees
that the period during which the covenant contained in this Section 5 shall be
effective shall be computed by excluding from


                                                                               4

<PAGE>

such computation any time during which Participant is in violation of any
provision of Section 5. Participant agrees that if any covenant contained in
Section 5 of this Agreement is found by a court of competent jurisdiction to
contain limitations as to time, geographical area, or scope of activity that are
not reasonable and impose a greater restraint than is necessary to protect the
goodwill or other business interest of the Company, then the court shall reform
the covenant to the extent necessary to cause the limitations contained in the
covenant as to time, geographical area, and scope of activity to be restrained
to be reasonable and to impose a restraint that is not greater than necessary to
protect the goodwill and other business interests of the Company and to enforce
the covenant as reformed.

     (e) Participant specifically recognizes and affirms that each of the
covenants contained in subdivisions (b) and (c) of this Section 5 is a material
and important term of this Agreement which has induced the Company to provide
for the award of Restricted Stock hereunder, the disclosure of confidential
information referenced herein, and the other promises made by the Company
herein, and Participant further agrees that should all or any part or
application of subdivisions (b) or (c) of Section 5 of this Agreement be held or
found invalid or unenforceable for any reason whatsoever by a court of competent
jurisdiction in an action between Participant and the Corporation, Compass, or
an affiliate of either, the Corporation shall be entitled to receive (but not
obligated to acquire) from Participant all Common Stock held by Participant
which was obtained by Participant under this Agreement (including all shares
obtained by virtue of any stock dividend or distribution, recapitalization,
merger, consolidation, split-up, combination, exchange of shares, or other
transaction, hereinafter "stock dividends") by returning to the Corporation each
share of Common Stock received by the Participant in respect of such Restricted
Stock (as adjusted for stock dividends). If Participant has sold, transferred,
or otherwise disposed of any shares of Common Stock obtained under this
Agreement (including all shares obtained by virtue of any stock dividends), the
Corporation shall be entitled to receive from Participant the fair market value
of the Common Stock (including all shares obtained by virtue of any stock
dividends) on the date of sale, transfer, or other disposition.

     (f) Notwithstanding any provision to the contrary herein contained, Section
5(b) shall not apply:

          (i) Upon the termination of the Participant's employment by the
     Corporation other than for Cause within one (1) year following a Sale of
     the Corporation; and

          (ii) Upon the voluntary termination of employment by the Participant
     for any reason within the thirty (30) day period immediately after the one
     (1) year period following a Sale of the Corporation.

     (g) This Section 5 replaces Section 5 in all restricted stock award
agreements between the Corporation and the Participant entered into as of a date
prior to the date of this Agreement. All such prior agreements are hereby
amended to include this Section 5 in place of Section 5 in any such prior
agreements.

     6. ADJUSTMENTS. In the event of any change in the outstanding Common Stock
of the Corporation by reason of a stock dividend or distribution,
recapitalization, merger, consolidation, split-up, combination, exchange of
shares or otherwise, the Committee shall adjust


                                                                               5

<PAGE>

the number of shares of Common Stock which may be issued under the Plan and the
Committee shall provide for an equitable adjustment of any shares issuable
pursuant to awards outstanding under the Plan.

     7. ASSIGNMENT AND TRANSFER. Participant may assign or transfer his rights
under this Agreement under the following circumstances: (i) by will or the laws
of descent and distribution, in which case the Restricted Stock may be received
in accordance with the provisions of this Agreement or (ii) by gift or pursuant
to a domestic relations order to a family member (or a trust for their benefit),
in which case the Participant shall promptly report the transfer to the
Secretary of the Corporation so that the Corporation may deliver to his
transferee all requisite documents concerning the Plan (including the prospectus
meeting the requirements of Section 10(a) of the Securities Act of 1933, as
amended). For this purpose, "family member" includes any child, stepchild,
grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling,
niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law,
brother-in-law, or sister-in-law, including adoptive relationships, a trust in
which these persons have more than fifty (50) percent of the beneficial
interest, a foundation in which these persons (or the Participant) control the
management of assets, and any other entity in which these persons (or the
Participant) own more than fifty (50) percent of the voting interests. A
transfer to an entity in which more than fifty (50) percent of the voting
interests are owned by family members, or the Participant, in exchange for an
interest in that entity is also permitted pursuant to this Section 7.

     8. DISPOSITION OF SHARES. Participant agrees to notify the Corporation
promptly of the sale, gift or other disposition of any shares of Common Stock
awarded pursuant to this Agreement.

     9. NO RIGHT TO CONTINUED EMPLOYMENT. Nothing contained in this Agreement
shall confer upon Participant any right with respect to continuance of
employment by the Corporation, or any affiliate, nor shall it interfere in any
way with the right of Participant's employer to terminate Participant's
employment at any time.

     10. COMPLIANCE WITH LAWS AND REGULATIONS. The obligation of the Corporation
to deliver shares of Restricted Stock hereunder shall be subject to all
applicable federal and state laws, rules and regulations and to such approvals
by any government or regulatory agency as may be required.

     11. PAYMENT OF TAXES. Participant shall, no later than the date as of which
the value of any portion of the Restricted Stock first becomes includable in the
Participant's gross income for federal income tax purposes, pay to the
Corporation, or make other arrangements satisfactory to the Committee regarding
payment of, any federal, state or local income, FICA, or other taxes of any kind
required by law to be withheld with respect to the Restricted Stock. The
obligations of the Corporation under this Agreement shall be conditioned on such
payment or arrangements, and the Corporation and its affiliates shall, to the
extent permitted by law, have the right to deduct such taxes from any payment of
any kind otherwise due to Participant.

     12. PARTICIPANT BOUND BY PLAN. Participant hereby acknowledges receipt of a
copy of the Plan and agrees to be bound by all the terms and provisions thereof,
including the terms and provisions adopted after the award of the Restricted
Stock but prior to the vesting thereof.


                                                                               6
