        4.    Crediting Earnings and Losses.    In accordance with, and subject
to, the rules and procedures that are established from time to time by the
Committee, in its sole discretion, amounts shall be credited or debited to a
Participant's Account in accordance with the following rules:

        (a)   Election of Measurement Funds.    Each Participant, including
former Participants with Accounts, shall elect the manner of deemed investment
of all amounts credited to his or her Account among the Measurement Funds (as
described in Section 4(c) below). By such election, the Participant may (but is
not required to) add or delete one or more Measurement Funds to be used to
determine the additional amounts to be credited to his or her Account balance,
or to change the portion of his or her Account allocated to each previously or
newly elected Measurement Fund. Such an election under this Section 4 may be
made on a daily basis through the voice response system provided by the
Committee's administrative delegate (or through such other system designated by
the Committee) and shall be effective as soon as reasonably possible thereafter.
Such an election must be in accordance with any and all rules and regulations
established by the Committee for this purpose. Any election made hereunder shall
continue to be effective until properly revoked by the Participant.

        (b)   Proportionate Allocation.    In making any election described in
Section 4(a) above, the Participant shall specify, in increments of 1%, the
percentage of his or her Account to be allocated to a Measurement Fund (as if
the Participant were making an investment in that Measurement Fund with that
portion of his or her Account).

        (c)   Measurement Funds.    The Participant may elect one or more of the
Measurement Funds (the "Measurement Funds") identified in Appendix A, attached
hereto and made a part hereof, for the purpose of crediting additional amounts
to his or her Account. As necessary, the Committee may, in its sole discretion,
discontinue, substitute or add a Measurement Fund.

        (d)   Crediting or Debiting Method.    The performance of each elected
Measurement Fund (either positive or negative) will be determined by the
Committee, in its sole discretion, based on the performance of the Measurement
Funds themselves. A Participant's Account shall be credited or debited as of the
end of each business day based on the performance of each Measurement Fund
elected by the Participant, as determined by the Committee in its sole
discretion.

        (e)   No Actual Investment.    Notwithstanding any other provision of
this Plan that may be interpreted to the contrary, the Measurement Funds are to
be used for measurement purposes only, and a Participant's election of any such
Measurement Fund, the allocation to his or her Account thereto, the calculation
of additional amounts and the crediting or debiting of such amounts to a
Participant's Account shall not be considered or construed in any manner as an
actual investment of his or her Account in any such Measurement Fund.

        (f)    Responsibility for Elections.    Neither the Company nor the
Committee shall have any liability as a result of, or be in any manner
responsible for, a Participant's individual deemed investment election or a
Participant's failure to make a deemed investment election, the Committee's only
duty being to credit the Participants' Accounts in accordance with the
Participants' deemed investment elections. To the extent that no deemed
investment election is in effect, the Committee shall credit such Participant's
Account as if such Participant's deemed

5

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

investment election were a money market mutual fund or other similar short-term
fixed-income fund selected by the Committee. The Committee may impose blackout
periods from time to time to facilitate introduction of new Measurement Funds or
to change the administrative delegate.

        (g)   Change in Method.    Notwithstanding the foregoing, the Committee
may change the method of crediting earnings or losses to Accounts under the
Plan, by written notice to each Participant, which notice shall specify the new
method for crediting earnings or losses to be used and the effective date for
such change.

        5.    Vesting.    

        (a)   A Participant shall become fully vested in the full value of the
amount credited to his or her Account upon attainment of age 55, death,
Disability, completion of at least five Years of Service or a Change in Control.

        (b)   A Participant whose employment with the Company or any Affiliated
Entity terminates prior to attainment of age 55 (for any reason other than death
or Disability) with fewer than five Years of Service will forfeit all amounts in
his or her Account upon his or her termination of employment.

        (c)   Notwithstanding anything in this Section 5 to the contrary, a
Participant shall always be fully vested in and have a nonforfeitable right in
the full value of the amount credited to his or her Account under Section 3(f)
relating to the TSSL Special Pension Supplement, under Section 3(g) relating to
the balances transferred from the Keystone Plan and under Section 3(h) relating
to the balances transferred from the ADT Plans.

        6.    Timing of Distribution.    Upon initial enrollment in the Plan, a
Participant shall irrevocably elect on a form prescribed by the Company to
commence distribution of his or her vested Account balance either (a) upon his
or her termination of employment, or (b) in any calendar year that is at least
five years from initial participation in the Plan as may be selected by the
Participant, but not later than the year in which the Participant attains age 70
(the "Distribution Year"). If no election is made, the distribution will
commence upon the Participant's termination of employment.

        7.    Method of Distribution.    

        (a)   Upon initial enrollment in the Plan, a Participant shall
irrevocably elect on a form prescribed by the Company to receive his or her
vested Account balance pursuant to one of the following payment options:

          (i)  A single lump sum to be paid as soon as practicable following the
quarter in which the Participant terminates his or her employment with the
Company or an Affiliated Entity or as soon as practicable in the beginning of
the Distribution Year.

         (ii)  Annual installments, in an amount determined in accordance with
Section 7(c), over a period not to exceed 15 years, beginning as soon as
practicable in the beginning of the calendar year next following the year in
which the Participant terminates his or her employment with the Company or an
Affiliated Entity or as soon as practicable in the beginning of the Distribution
Year.

If no election is made, the distribution will be made in a lump sum pursuant to
(i) above.

        (b)   All amounts credited to each Participant's Account which become
payable hereunder shall be paid by the Company or an Affiliated Entity in cash.
Each such Account shall be charged with the amount distributed with respect
thereto as of the date of payment.

        (c)   In the event a benefit is paid in a single lump sum, the value of
a Participant's Account shall be determined as of the end of the Quarter
following the Participant's termination of

6

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

employment, or the end of the last Quarter immediately preceding the
Distribution Year, as the case may be.

        (d)   In the event a benefit is paid in installments, each annual
installment payment amount shall be determined in the following manner:

          (i)  the value of the Participant's Account balance as of the end of
the Quarter preceding the payment, divided by

         (ii)  the total number of installment payments not yet made.

        8.    Payments Upon Death.    

        (a)   In the event of a Participant's death prior to his or her
termination of employment with the Company or an Affiliated Entity, the value of
the amount credited to the Participant's Account as determined under Section 7
shall be paid to the Participant's Beneficiary in a single lump sum as soon as
practicable after such Participant's death.

        (b)   In the event of a Participant's death after his or her termination
of employment but before full distribution of the amounts to be paid to him or
her pursuant to Section 7 has been completed, the value of the amounts payable
under Section 7 shall be paid to the Participant's Beneficiary in a single lump
sum as soon as is practicable after such Participant's death.

        (c)   Each Participant may designate, from time to time, a Beneficiary
or Beneficiaries (who may be named contingently or successively) to whom any
amounts which remain credited to the Participant's Account at the time of his or
her death shall be paid. Each such designation shall revoke all prior
designations by the same Participant, except to the extent otherwise
specifically noted, shall be in a form prescribed by the Company and shall be
effective only when filed by the Participant in writing with, and acknowledged
by, the Company during his or her lifetime.

        9.    No Funding Required.    

        (a)   Nothing in this Plan will be construed to create a trust or to
obligate the Company or any other person to segregate a fund, purchase an
insurance contract, or in any other way to fund currently the future payment of
any benefits hereunder, nor will anything herein be construed to give any
Participant or any other person rights to any specific assets of the Company or
of any other person. Except as described in (b) below, any benefits which become
payable hereunder shall be paid from the general assets of the Company.

        (b)   The Company in its sole discretion may establish a grantor or
other trust of which the Company is treated as the owner under the Code, to
provide for the payment of benefits hereunder, subject to the claims of the
Company's general creditors in the event of insolvency, and subject to such
other terms and conditions as the Company may deem necessary or advisable to
ensure (i) that benefits are not includible, by reason of the establishment or
funding of such trust, in the income of trust beneficiaries prior to actual
distribution and (ii) that the existence of such trust does not cause the Plan
or any other arrangement to be considered funded for purposes of Title I of
ERISA.

        10.    Plan Administration and Interpretation.    The Company shall have
complete control over the administration of the Plan and complete control and
authority to determine, in its sole discretion, the rights and benefits and all
claims, demands and actions arising out of the provisions of the Plan of any
Participant, Beneficiary, or other person having or claiming to have any
interest under the Plan and the Company's determinations shall be conclusive and
binding on all such parties. The Company shall be deemed to be the Plan
Administrator with the responsibility for complying with any reporting and
disclosure requirements of ERISA. The rights of the Company hereunder shall be
exercised by the Committee. To the extent that the Committee is unable or
unwilling to exercise any right hereunder or

7

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

make any determination hereunder, however, the Board of Directors shall exercise
such right or make such determination.

legal representative or any Beneficiary designated by him or her shall have any
right, other than the right of an unsecured general creditor, against the
Company in respect of the Account of such Participant established hereunder.

        19.    Effective Date.    This Plan shall be effective as of January 1,
1995, and shall continue in existence thereafter until terminated pursuant to
