providing deferred compensation for a select group of management or highly

increase their efforts for its welfare by providing them with supplemental
benefits notwithstanding the limitations imposed by the Internal Revenue Code

This Plan is strictly a voluntary undertaking on the part of the Company

with the right of the Company or an Affiliate, as the case may be, to discharge
any employee at any time, nor shall this Plan interfere with the right of the
Company or an Affiliate, as the case may be, to establish the terms and
conditions of employment of any employee.

of the Company and participants herein shall not be entitled to look to any
source for payment of such benefits other than the general assets of the

##### 



if the Kaplan Key Employee Participant had been covered under the TWPC
Retirement Benefits Schedule to The Retirement Plan for Washington Post
Companies and (ii) the aggregate spouses benefit payable to such Surviving
Spouse under the Kaplan Cash Balance Retirement Benefits Schedule of The

(iii)   For purposes of calculating the Supplemental Retirement Benefit or the
Surviving Spouses benefit hereunder for (i) an Executive Participant or the
Surviving Spouse of an Executive Participant, or (ii) a Kaplan Key Employee
Participant or the Surviving Spouse of a Kaplan Key Employee Participant with
respect solely to years of Service at Kaplan, Inc. or any affiliate of Kaplan,
Inc., as the case may be, Compensation rather than Actual Salary will be used.

(b)    (i) Except as provided below, the Supplemental Retirement Benefits
provided by this Plan shall be paid to the Participant (or to any beneficiary
designated by him or her in accordance with the Retirement Plans, or to his or
her Surviving Spouse if eligible for and receiving a spouses benefit under the
Retirement Plans) concurrently with the payment of the benefits payable under
the applicable Retirement Plan in which he or she was participating at the date
of termination and/or in which he or she had a vested right on such date and
shall be payable in the same form as such Retirement Plan benefits are being
paid thereunder.

(ii)    Notwithstanding the above, with respect to a Participant covered by
the Cash Balance Pension provisions of The Retirement Plan for Washington Post
Companies, the single life annuity available shall be determined using the GATT
Interest Rate (as defined in such Retirement Plan) plus 2%. In the event the
Supplemental Retirement Benefit commences prior to Normal Retirement Date or is
payable in a form other than an annuity for the life of the former employee
only, the Supplemental Retirement Benefit shall be actuarially adjusted in the
same manner as are benefits payable under the Retirement Plan in which he or
she was participating at the time of termination and/or in which he or she had
a vested right on such date. The Committee may, however, in its sole
discretion direct

##### 



that the Supplemental Retirement Benefit payable with respect to a former
employee be paid as an actuarially equivalent single sum payment; provided,
that (except for a distribution to pay taxes as provided in Section 5) no such
payment may be made prior to termination of Service or prior to the date that
benefits may become payable under any of the Retirement Plans, and provided,
further, that in determining actuarial equivalency of a single sum payment in
cash, there shall be used the same actuarial assumptions as are applicable for
the calculation of a single sum payment under the applicable Retirement Plan.
Further notwithstanding the above and except in the case of a Kaplan Key
Employee Participant, if the Participant elects a lump sum payment in
accordance with the Cash Balance Pension provisions of The Retirement Plan for
Washington Post Companies, the benefits under the Supplemental Retirement Plan
will also be payable in a lump sum amount which shall be equal to his or her
Supplemental Benefit Cash Balance Account as of the date of the lump sum
payment. A Kaplan Key Employee Participant cannot elect to receive the amount
of his or her Supplemental Benefit in a lump sum regardless of his or her
election to receive a lump sum payment in accordance with the Kaplan Cash
Balance Retirement Benefits Schedule of The Retirement Plan for Washington Post
Companies.

(iii)    For purposes of the Supplemental Retirement Benefits provided by
this Plan to be paid to a Kaplan Key Employee Participant (or to his or her
Surviving Spouse if eligible for and receiving a spouses benefit under the
Retirement Plans) with respect to his or her years of Service with Kaplan, Inc.
or an affiliate of Kaplan, Inc., the Unrestricted Benefit or the Unrestricted
Spouses Benefit shall be calculated as an annuity. If a Kaplan Key Employee
Participant elects to receive a lump sum benefit from his or her Cash Balance
Account under The Retirement Plan for Washington Post Companies, then the
Supplemental Retirement Benefit for such Participant will be paid in the form
of a single life annuity beginning at the same time the payment is commenced
under The Retirement Plan for Washington Post Companies, but in no case prior
to age 55.

##### 



(a)    In the event that the Actual Salary of an Executive Participant
designated as eligible to receive benefits under this Section 4 for 1989 or any
subsequent Plan Year exceeds the 401(a)(17) Limitations for such Plan Year,
such Executive Participant shall be eligible to make additional salary
reduction contributions under this Plan and receive a Supplemental Savings
Award under this Plan for such Plan Year; provided, that such Executive
Participant is then participating in his or her employers Savings Plan and
making (i) the maximum allowable basic, matchable tax-deferred contributions to
such Savings Plan and (ii) the maximum allowable after-tax contributions which
can result in a matching employer contribution, as permitted under such Savings
Plan, after taking into account the application of the non-discrimination rules
of Sections 401(k) and (m) of the Internal Revenue Code for such Plan Year. In
order to compute the amount of such Supplemental Savings Award, a determination
will be made of the dollar amount of contributions the Executive Participant is
able to make to his or her employers Savings Plan which result in matching
employer contributions for such Executive Participant under the terms of such
Savings Plan. This dollar amount will then be expressed as a percentage (the
Applicable Percentage) of the amount of compensation which can be recognized
for purposes of the Savings Plan under Section 401(a)(17) of the Internal
Revenue Code for the then-current Plan Year. Prior to the beginning of each
Plan Year, the Executive Participant will be provided with the opportunity to
elect to irrevocably defer under this Plan the Applicable Percentage (or any
whole lower percentage) of the Executive Participants Actual Salary earned in
excess of the 401(a)(17) Limitations for such Plan Year. Such a salary
reduction is referred to as a Supplemental Basic Contribution. In the event
that an Executive Participant elects to make a Supplemental Basic Contribution
under this Plan and, to the extent the Company is not his or her employer, his
or her employer forwards on a timely basis such Supplemental Basic Contribution
to the Company, such individual will receive a Supplemental Savings Award under
this Plan in the form of (i) a matching contribution equal to the product of
the Executive Participants Supplemental Basic Contribution times the matching
employer contribution percentage

##### 



under the terms of the applicable Savings Plan and (ii) to the extent such
Participants employer makes an unmatched contribution to the applicable
Savings Plan on behalf of such Participant, a contribution equal to the
difference between the amount of such unmatched contribution actually made
under such Savings Plan on behalf of such Participant and the amount of such
unmatched contribution such Participant would have received under such Savings
Plan if the 401(a)(17) Limitations had not been in effect (the Supplemental
Savings Award). The Supplemental Savings Award for any Plan Year shall be
made as of the first day of the following year or on such other basis as may be
approved by the Committee.

(b)    The amount of an Executive Participants supplemental savings plan
benefits under this Plan shall be the aggregate amount of the Supplemental
Savings Awards and the Supplemental Basic Contributions together with
investment credits accrued thereon (the Supplemental Savings Account).
Investment credits shall be credited on the amount of an Executive
Participants Supplemental Savings Account at the end of such Plan Year or on
such other basis as may be approved by the Committee in accordance with the
Executive Participants Investment Election.

In the event an Executive Participant fails to complete a valid Investment
Election, his or her Supplemental Savings Account will be credited with the
investment credit amounts equivalent to the rates of return generated by the
money market option under the Companys 401(k) plan.

(c)    The Compensation Committee shall establish the investment credit
factors that will be available in any Plan Year.

(d)    Supplemental Savings Awards and the investment credits thereon shall
be fully vested and nonforfeitable.

(e)    No withdrawal of funds in an Executive Participants Supplemental
Savings Account for hardship or any other reason may be made while an Executive
Participant remains employed by the Company or an Affiliate. The Supplemental
Savings Account shall be paid in cash as soon as practicable following
termination of Service.

##### 



(f)    An Executive Participant shall designate a beneficiary to receive the
unpaid portion of his or her Supplemental Savings Account in the event of his
or her death. The designation shall be made in a writing filed with the
Committee on a form approved by it and signed by the Executive Participant. If
no effective designation of beneficiary shall be on file with the Committee
when supplemental savings benefits would otherwise be distributable to a
beneficiary, then such benefits shall be distributed to the Surviving Spouse of
the Executive Participant or, if there is no Surviving Spouse, to his or her
estate.

Section 5. Funding. Benefits under this Plan shall not be funded in
order that the Plan may be exempt from the provisions of Parts 2, 3 and 4 of
Title I of ERISA. The Committee shall maintain records of Supplemental Savings
Accounts and records for the calculation of supplemental retirement benefits.
In the event benefits are hereafter determined to be taxable for Participants
prior to actual receipt thereof, a payment may be made to such Participants in
an amount sufficient to pay such taxes notwithstanding that the Participant may
not then have terminated Service or that the payment is being made prior to the
date that benefits would otherwise be paid under any of the Retirement Plans.
Amounts so paid (i) with respect to supplemental savings benefits shall reduce
the Executive Participants Supplemental Savings Account and (ii) with respect
to Supplemental Retirement Benefits shall be used as an offset to the
Supplemental Retirement Benefits, if any, thereafter payable.

Section 6. Administration. This Plan shall be administered by the
Committee. All decisions and interpretations of the Committee shall be
conclusive and binding on the Company, and the Participants. The Plan may be
amended or terminated by the Board of Directors of the Company at any time and
any Participant may have his or her designation as such terminated by the
Committee at any time; provided, however, that no such amendment or termination
or change in designation shall deprive any Participant of supplemental
retirement or savings benefits accrued to the date of such amendment or

11

##### 



termination or modify the last two sentences of Section 5 in a manner
adverse to any Participant.

Section 7. Loss of Benefits. Notwithstanding any other section of this
Plan, if a Participant is discharged by the Company or an Affiliate because of
conduct that the Participant knew or should have known was detrimental to
legitimate interests of the Company or its Affiliates, dishonesty, fraud,
misappropriation of funds or confidential, secret or proprietary information
belonging to the Company or an Affiliate or commission of a crime, such
Participants rights to any benefits under this Plan shall be forfeited; except
that such Participant shall be entitled to receive the aggregate amount of his
or her Supplemental Basic Contributions, without any interest, in such event.

Section 8. Nonassignability. No Participant, or beneficiary shall have
the right to assign, pledge or otherwise dispose of any benefits payable to him
or her hereunder nor shall any benefit hereunder be subject to garnishment,
attachment, transfer by operation of law, or any legal process.

Section 9. Limitation of Liability. The Companys sole obligation under
this Plan is to pay the benefits provided for herein and neither the
Participant nor any other person shall have any legal or equitable right
against the Company, an Affiliate, the Boards of Directors thereof, the
Committee or any officer or employee of the Company or an Affiliate other than
the right against the Company to receive such payments from the Company as
provided herein.

Section 10. Use of Masculine and Feminine; Singular and Plural. Wherever
used in this Plan, the masculine gender will include the feminine gender and
the singular will include the plural, unless the context indicates otherwise.
