form (an "Election Form") to each Participant which will provide as follows:

                          any portion of his or her Compensation for such Plan
                          Year by completing the Election Form;

                 (b)      That the Employee's election to defer receipt of
                          Compensation will be effective on the first day of the
                          Plan Year immediately following such Enrollment
                          Period;

                 (c)      That the Election Form must be completed and returned
                          to the Plan Administrator prior to the termination of
                          the Enrollment Period; and

                 (d)      That the Election Form may not be revised or revoked
                          by the Employee during the Plan Year for any reason.

         5.2     FAILURE TO ELECT.  If a Participant fails to return an
Election Form to the Plan Administrator prior to the end of an Enrollment
Period, the Participant will not be eligible to have the payment of all or any
portion of the Participant's Compensation deferred for the Plan Year immediately
following such


                                       4
<PAGE>

Enrollment Period. However, a Participant who fails to timely submit an Election
Form prior to the end of an Enrollment Period, will be allowed to submit an
Election Form during any subsequent Enrollment Period for subsequent Plan Years.

         5.3 REVISION OF ELECTION FORM. No Participant may revise his or her
Election Form during a Plan Year.

                                   ARTICLE VI

              DISTRIBUTION OF BENEFITS UPON CESSATION OF EMPLOYMENT

         6.1 VESTING IN COMPENSATION DEFERRAL ACCOUNT. Notwithstanding anything
herein contained to the contrary, each Participant shall at all times be fully
vested in such Participant's Compensation Deferral Account. Upon the date a
Participant becomes entitled to a distribution of his or her Company Account as
provided in Sections 6.2 through 6.7 hereof (or in the case of a Participant who
is "Terminated For Cause" as defined in Section 6.5 hereof, upon the date a
Participant would be entitled to a distribution but for the application of
Section 6.5 hereof), the Participant shall also be entitled to receive a
distribution of his or her Compensation Deferral Account.

         6.2 DISABILITY AND RETIREMENT. Upon the date a Participant is either
(a) determined to be suffering from a Disability or (b) reaches his or her
Retirement Date, the Participant shall fully vest in the entire balance of his
or her Company Account and such Participant's Company Account shall be
distributed to such Participant in the manner set forth in Section 6.7 hereof.

         6.3 TERMINATION OF EMPLOYMENT. In the event any Participant ceases to
be an Employee prior to the Participant's Retirement Date for any reason other
than the death or Disability of the Participant, the Participant shall, subject
to the provisions of Sections 6.5 and 6.6 hereof, become vested in the balance
of his or her Company Account in accordance with the following schedule:

<TABLE>
<CAPTION>
         IF TERMINATION OCCURS                       VESTED PERCENTAGE
         ---------------------                       -----------------
<S>                                                         <C>
 Prior to Date Employee Attains Age 55                        0%

 Prior to Date Employee Attains Age 60                       50%
 But on or after Date Employee
 Attains Age 55

 On or after Date Employee Attains Age 60                   100%
</TABLE>

A Participant who ceases to be an Employee of the Company shall have such vested
amounts of the Participant's Company Account distributed to him or her in the
manner set forth in Section 6.7 hereof and such Participant shall forfeit the
nonvested portion of his or her Account which funds shall revert to and become
the property of the Company.


                                       5
<PAGE>

         6.4 DEATH. Upon the death of a Participant, the Participant shall fully
vest in the entire balance of his or her Company Account. Upon the death of a
Participant, all proceeds of life insurance policies, insuring the life of such
Participant and payable to the Trust shall be allocated to such Participant's
Compensation Deferral Account and the entire balance of the
Participant's Company Account and Compensation Deferral Account, including any
life insurance proceeds allocated to such Accounts as set forth above, shall be
distributed to such Participant's Beneficiary in one lump sum within sixty (60)
days following the close of the Plan Year in which the Participant dies (or at
such earlier time as the Plan Administrator shall determine), provided, that, in
the event any life insurance proceeds have not been received by the Trust by
such date, such life insurance proceeds shall be distributed to such
Participant's Beneficiary within sixty (60) days of the Trust's receipt thereof.

         6.5     TERMINATION FOR CAUSE.  Notwithstanding the provisions of
Section 6.3 hereof, any Participant whose employment with the Company shall be
"Terminated For Cause" prior to the time such Participant has reached his or her
Retirement Date, shall forfeit any and all rights to his or her Company Account
and such funds shall become the property of the Company. For purposes of this
Plan, a Participant shall be deemed to be Terminated For Cause if the Committee
shall have made a good faith determination that:

         (a)     The Participant has committed gross neglect in the performance
                 of any duties required by the Company to be performed by such
                 Participant;

         (b)     The Participant has committed an act of theft or fraud while
                 in the employ of the Company; or

         (c)     The Participant shall commit acts of repeated insubordination
                 to the Company.

         6.6 CHANGE OF CONTROL. Notwithstanding the provisions of Section 6.3
hereof, if at any time there shall be a sale of substantially all of the assets
of the Company or a sale of more than fifty percent (50%) of the outstanding
shares of voting common stock of the Company, each Participant's
Company Account shall fully vest in such Participant and become distributable as
provided in Section 6.7 hereof. The foregoing notwithstanding, a Participant's
Company Account shall fully vest in such Participant and payment thereon may be
made to such Participant pursuant
to this Section only to the extent that such
accelerated vesting or payment would not create an excess parachute payment
under Section 280G or Section 4999 of the Internal Revenue Code of 1986, as
amended. Notwithstanding the above, this Section 6.6 shall not be triggered by
the acquisition of stock in the Company by Morgan, Lewis, Githens & Ahn, Inc.
prior to October 31, 1995.

         6.7 DISTRIBUTIONS UPON TERMINATION OF EMPLOYMENT. Upon the termination
of the Participant's full time employment with the Company, for any reason other
than death, whether voluntary or involuntary, with or without cause, the entire
vested balance of the Participant's Company Account and


                                       6
<PAGE>

Compensation Deferral Account (subject to the forfeiture as provided for in
Section 6.5 hereof) shall be distributed to such Participant in monthly
installments for a period of sixty (60) months, with the first such installment
being due and payable within sixty (60) days following the termination of the
Participant's employment with the Company, the amount of which installments
shall be equal to that portion of the Participant's vested and nonforfeited
Accounts as is determined by multiplying the balance thereof (including any
allocations of income, earnings, gain or loss) by a fraction, the numerator of
which shall be one (1) and the denominator of which shall be the number of
remaining installment payments to be made. Notwithstanding the above, the Plan
Administrator may accelerate the payment of such distribution if he deems such
acceleration to be in the best interests of such Participant. No Participant
shall have any right to require the acceleration of any distribution to such
Participant. During the period of any installment distribution, the vested and
nonforfeited amounts remaining in such Participant's Account shall continue to
be held by the Trust and invested in accordance with the terms of the Trust.

                                   ARTICLE VII

                 the denial of the claim within the ninety (90) day period
                 specified in Section 7.2(b) hereof, then the claim shall be

                                  MISCELLANEOUS

          8.1 ADMINISTRATION. This plan shall be operated and administered by
the Committee, which shall, for the purposes of this Plan, be the Plan
Administrator. The construction and interpretation by the Plan Administrator of
any provision of this Plan shall be final and conclusive, unless otherwise
determined by the Plan Administrator or otherwise decided by the Claims
Manager. No member of the Committee, nor any person to whom the Committee
delegated its authority pursuant to the foregoing, shall be liable for any
action or determination made by him or her in good faith.

         8.2 NONALIENATION OF BENEFITS. No Participant shall have the right to
assign, pledge, sell, anticipate, encumber or transfer his or her benefits under
this Plan in any manner whatsoever. No assignment, pledge, sale, anticipation,
encumbrance or transfer of any of the benefits under this Plan made by any
Participant shall be valid or recognized by the Company.

         8.3 AMENDMENT OR TERMINATION. This Plan may be amended or terminated by
the Company at any time; provided, however, no such amendment or termination
shall impair or diminish in any manner whatsoever the Participant's rights to
amounts allocated to Participant's Accounts prior to such amendment or
termination.

         8.4 RESTRICTIONS ON PARTICIPANTS' RIGHTS. The benefits granted or
allocated to any Participant pursuant to this Plan do not constitute any stock
of the Company nor shall they evidence any indebtedness of the Company, but,
rather, shall constitute only a right to receive benefits which are payable
pursuant to the terms and conditions provided herein. Notwithstanding anything
herein to the contrary, nothing in this Plan shall:

         (a)     Give any Participant any rights in any stock of the Company
                 currently outstanding or hereafter issued;


                                       8

                 or

         (c)     Create any right of employment in any Participant, limit the
                 Company's rights to terminate the employment of any
                 Participant, or evidence any agreement or understanding that
                 the Company will employ a Participant in any particular
                 position, at any particular rate of remuneration or for any
                 particular length of time.

         8.4 DESIGNATION OF BENEFICIARY. Each Employee, upon becoming a
Participant, shall file with the Plan Administrator, a notice in writing
designating one or more beneficiaries to whom payments otherwise due the
Participant pursuant to this Plan shall be made in the event of such
Participant's death. A Participant shall have the right to change the
beneficiary or beneficiaries from time to time but no such change shall become
effective until submitted in writing to the Plan Administrator. In the event no
designation of beneficiary is made by a Participant or if all of the
beneficiaries a Participant shall have designated shall be deceased, the
deceased Participant shall be deemed to have designated his or her estate as
beneficiary hereunder.

         8.5 GOVERNING LAW. This Plan shall be construed and governed by the
laws of the State of Ohio, to the extent not preempted by Federal law.

         8.6 PARTICIPANT AS COMMITTEE MEMBER. No person who is a member of the
Committee shall take part in any decision regarding the eligibility of such
member to become a Participant in this Plan, the eligibility of such member as a
Participant to share in any Company contribution for any Plan Year, the right of
such member to receive an accelerated distribution hereunder, or in any
other election or decision as a Committee member which affects such member's
rights as a Participant hereunder. The provisions of this Section 8.6 shall
apply notwithstanding anything in this Plan or in the Trust to the contrary.
