and the number of months between the Participant's Termination Date and his or

Date precedes his or her Normal Retirement Date by more than 10 years but not

respect to such periods of part-time service shall be appropriately adjusted to
a full-time basis. In the event that a Participant is paid an annual bonus
during the 12-month period commencing on his or her Termination Date, for
purposes of calculating the Participant's Final Average Compensation the amount
of such bonus shall be substituted for the amount of the first bonus taken into
account during the applicable 60-month period, but only if (i) the 60-month
period used for purposes of the Final Average Compensation calculation includes

the date he or she becomes an Eligible Employee.

ARTICLE 4. RETIREMENT BENEFIT

4.01 Amount of Benefit.

     (a) Each Participant shall be entitled under this Plan following his or her
retirement or other Termination of Employment to a benefit (the "Retirement
Benefit") equal to the Participant's Gross Benefit reduced by his or her Offset
Benefits.

     (b) The Gross Benefit under the Plan, expressed as a single life annuity
commencing on the Participant's Termination Date, shall be the Applicable
Percentage of the product of (i) the Participant's Years of Service (not to
exceed 30) and (ii) 2% of the Participant's Final Average Compensation.

     (c) The Participant's Offset Benefits shall consist of the following
benefits to which the Participant is or will become entitled, or which the
Participant received prior to the date of determination:

         (1) All benefits paid or accrued under all qualified or nonqualified
defined benefit or defined contribution retirement plans sponsored by an
Affiliated Company; provided, however, that only the portion of any such benefit
attributable to Affiliated Company contributions shall be taken into account.
For purposes of the preceding sentence, Affiliated Company contributions shall
not include a Participant's elective deferrals under any such plan, or earnings
credited to any such elective deferrals to the extent such earnings are based on
a reasonable interest rate or on one or more predetermined investments.

         (2) The employer portion of any social security or other retirement
benefits provided by any Federal, state, local, or foreign government. Such
employer portion shall be equal, in the case of a social security benefit, to
the employer portion of the Participant's projected social security benefit (at
the Participant's social security full benefit retirement age) multiplied by a
fraction the numerator of which is the Participant's Years of Service and the
denominator of which is 35. For purposes of determining a Participant's
projected social security benefit, it shall be assumed that the social security
wage base remains constant in years following the Participant's Termination of
Employment and that in each of the 35 years prior to the Participant's social
security full benefit retirement age he or she has earned income of at least the
social security wage base applicable to such year.

     (d) In the event an Offset Benefit is not payable in the form of a single
life annuity commencing on the Participant's Termination Date, the offset
calculation in Section 4.01(a) shall be performed using such actuarial and other
adjustments as the Administrator shall determine.

4.02 Automatic Cash-Outs. Notwithstanding the provisions of Sections 4.02 and
4.03, in the case of any Participant who has a Termination of Employment:

         (1) Before his or her Normal Retirement Age and either before
attaining age 55 or before having completed 10 Years of Service; or

         (2) At a time when the lump-sum value of his or her Retirement Benefit
under the Plan is $50,000 or less the Participant's Retirement Benefit shall
automatically be paid in a lump sum within 30 days after his or her Termination
of Employment.
   4
4.03 Automatic Payments in Other Circumstances. In the case of any Participant
to whom Section 4.02 does not apply and for whom no valid election under Section
4.04 is in effect, such Participant's Retirement Benefit shall be paid in the
manner set forth in this Section 4.03.

     (a) If the Participant participates in one or more qualified defined
benefit plans sponsored by an Affiliated Company, the Participant's benefit
shall commence at the same time and be paid in the same form as the
Participant's benefit under that qualified plan. If the Participant is covered
under more than one such plan, the plan in which he or she has the greatest
benefit will be controlling.

     (b) If the Participant does not participate in any qualified defined
benefit plan sponsored by an Affiliated Company, the Participant's benefit shall
be paid as an actuarially reduced 50% joint and survivor annuity (if the
Participant is married) or a single life annuity (if the Participant is
unmarried), commencing in either case at his or her Normal Retirement Date (or,
if later, the first day of the month coinciding with or next following the date
of his or her actual retirement).



4.04 Election of Optional Forms of Benefit.

     (a) A Participant may file an election with the Administrator, on such form
as the Administrator shall prescribe, specifying (i) the form in which his
Retirement Benefit is to be paid and (ii) the time at which such benefit is to
commence in the event of the Participant's retirement or other termination of
employment before his or her Normal Retirement Age. Such election may, subject
to Section 4.04(c), be changed at any time.

     (b) If a valid election is in effect pursuant to this Section 4.04, except
as otherwise provided in Section 4.02 a Participant's Retirement Benefit shall
be paid in the form specified in such election. Such Retirement Benefit shall
commence (i) on the Participant's Normal Retirement Date (or, if later, the
first day of the month coinciding with or next following the date of the
Participant's actual retirement) if the Participant retires at or after his or
her Normal Retirement Age, (ii) in other cases, on the date specified in the
Participant's election.

     (c) An election or change in election pursuant to Section 4.04(a) shall be
valid only if filed with the Administrator either (i) by December 31, 1997 or
within 90 days after a Participant becomes eligible to participate in the Plan,
whichever is later, or (ii) at least 12 months before he or she retires or
otherwise terminates employment. Notwithstanding the preceding sentence, if a
Participant whose most recent valid election is for an annuity form of benefit
demonstrates to the satisfaction of the Administrator that a relevant change in
family circumstances has occurred since the filing of such election, such
participant may change his election to a different form of annuity commencing on
the same date as that specified on such prior election, or may designate a new
contingent Beneficiary, without regard to such 12-month requirement.

     (d) If, pursuant to Section 4.04(c), a change in a Participant's election
is not valid, the valid election previously in effect shall determine the form
and timing of the Participant's Retirement Benefit.

     (e) The forms of benefit that a Participant may elect under the Plan are
(i) a single life annuity, (ii) a 100% or 50% joint and survivor annuity, or
(iii) a single life annuity with 120-month period certain. A lump-sum payment
generally is not available as an elective form of benefit. A Participant may
indicate on an election that the Participant wishes to receive his or her
benefit in a lump sum, but in that event must also indicate the form in which
the Participant wishes the benefit to be paid if the lump-sum request is denied.
Requests for lump-sum payments will be considered by the Administrator on a
case-by-case basis, and the granting of any such request shall be within the
Administrator's sole discretion.

     (f) A participant who elects a joint and survivor form of benefit shall
designate his contingent Beneficiary in conjunction with such election. In the
event of such Beneficiary's death before the Retirement Benefit Date, the
participant's Retirement Benefit shall be paid in the form of a single life
annuity unless he has filed a valid change in election pursuant to Section
4.04(c).

4.05 Disability.
   5
     A Participant who incurs a Disability as an Employee shall continue to
accrue Years of Service during his or her period of Disability. Upon the
Participant's subsequent termination of employment, retirement or death
following cessation of his or her Disability, he or she (or his or her
Beneficiary) shall be entitled to receive distribution of his or her Retirement
Benefit or Death Benefit pursuant to the other provisions of the Plan. For
purposes of calculating such Retirement Benefit, the Participant's Final Average
Compensation shall be determined as of the commencement of his or her
Disability.


ARTICLE 5.  DEATH BENEFIT

5.01 In the event of a Participant's death prior to the commencement of payment
of his or her Retirement Benefit, the Participant's Beneficiary shall be paid
within 30 days after the Administrator receives notification of the
Participant's death, a lump-sum Death Benefit equal to the Retirement Benefit
the Participant would have received had he or she had a Termination of
Employment immediately before his or her death (or on the Participant's actual
Termination Date, if earlier) and elected to receive his or her benefit in a
lump sum. In calculating such Retirement Benefit, the amount of any Offset
Benefits shall be determined without regard to the fact of the Participant's
death.


ARTICLE 6. ADMINISTRATION

6.01 This Plan shall be administered by the Administrator. The Administrator
shall have discretionary authority to interpret the Plan and to adopt rules and
regulations consistent with the Plan. The Administrator's good-faith
determination with respect to any issue relating to the interpretation of the
Plan shall be conclusive and final.


ARTICLE 7. GENERAL PROVISIONS

7.01 No Contract of Employment. The establishment of the Plan shall not be
construed as conferring any legal rights upon any Participant for a continuation
of employment, nor shall it interfere with the rights of the Company to
discharge a Participant and to treat him without regard to the effect which such
treatment might have upon him as a Participant in the Plan.

7.02 Withholding. As a condition to a Participant's entitlement to benefits
hereunder, the Company shall have the right to deduct (or cause to be deducted)
from any amounts otherwise payable to a Participant, whether pursuant to the
Plan or otherwise, or otherwise to collect from the Participant, any required
withholding taxes with respect to benefits under the Plan.

7.03 Anti-Alienation Provisions. Subject to any applicable law, no benefit under
the Plan shall be subject in any manner to, nor shall the Company be obligated
to recognize, any purported anticipation, alienation, sale, transfer,
assignment, pledge, encumbrance, or charge, and any attempt to do so shall be
void. No such benefit shall in any manner be liable for or subject to
garnishment, attachment, execution, or a levy, or liable for or subject to the
debts, contracts, liabilities, engagements, or torts of the Participant.

7.04 Unfunded Benefits. The Plan is an unfunded plan maintained by the Company
for the purpose of providing deferred compensation for a select group of
management or highly compensated employees. The Plan shall not be construed as
conferring on a Participant any right, title, interest, or claim in or to any
specific asset, reserve, account, or property of any kind possessed by the
Company. To the extent that a Participant or any other person acquires a right
to receive payments from the Company, such rights shall be no greater than the
rights of an unsecured general creditor.

7.05 Claim for Benefits. Any claim for benefits under the Plan shall be made in
writing to the Administrator. If a claim is denied, the Administrator shall so
notify the Participant within 90 days after receipt of the claim. The notice of
denial shall state (i) the specific reason for the denial of the claim, (ii)
specific references to the pertinent Plan provisions upon which the denial is
based, (iii) a description of any additional material or information necessary
to perfect the claim together with an explanation of why such material or
information is necessary, and (iv) an explanation of the claims review
procedure.
   6
     Within 60 days after the Participant's receipt of notice of denial of a
claim, the Participant may (i) file a request with the Administrator that it
conduct a full and fair review of the denial of the claim, (ii) review pertinent
documents, and (iii) submit questions and comments to the Administrator in
writing.

     The decision by the Administrator with respect to the review must be given
within 60 days after receipt of the request, unless special circumstances
require an extension. In no event shall the decision be delayed beyond 120 days
after receipt of the request for review. The decision shall be written in a
manner calculated to be understood by the Participant and shall contain specific
reasons for the decision and a specific reference to the Plan provisions upon
which the decision is based.

7.06 Incapacity. If the Administrator determines that any person to whom a
benefit is payable under the Plan is unable to care for his or her affairs
because of illness or accident, any payment due may be paid to the individual's
spouse, child, parent, sibling, or to any person deemed by the administrator to
have incurred expense for such person otherwise entitled to payment unless a
prior claim therefor shall have been made by a duly appointed guardian,
committee, or other legal representative.

7.07 Successor Entities. This plan shall be binding upon the successors and
assigns of the Company. The Company shall require any successor (whether direct
or indirect, and whether by purchase, merger, consolidation, or otherwise) to
all or substantially all of the business or assets of the Company, by written
agreement to expressly assume and agree to perform the Company's obligations
under the Plan in the same manner and to the same extent that the Company would
be required to perform them if no such succession had taken place. The
provisions of this Section 7.07 shall continue to apply to each subsequent
employer of the Participant hereunder in the event of any subsequent merger,
consolidation, or transfer of assets of such subsequent employer.

7.08 Prior Plan. Effective as of the date of adoption of this Plan, the Prior
Plan has been terminated, and Participants are entitled to no further benefits
thereunder. In no event shall the accrued benefit of such a Participant under
this Plan be less than his or her accrued benefit under the Prior Plan
immediately prior to such termination.

7.09 Governing Law. The laws of the State of New York shall govern the
construction of this Plan and the rights and the liabilities hereunder of the
parties hereto.

7.10 Plan Year. The plan year shall be the calendar year.

7.11 Headings. All headings are inserted solely for reference and shall not
constitute a part of this Plan, nor affect its meaning, construction, or effect.
