                         METROPOLITAN LIFE SUPPLEMENTAL

                      AUXILIARY SAVINGS AND INVESTMENT PLAN

      Metropolitan Life Insurance Company, with respect to its own employees,
and Metropolitan Property and Casualty Insurance Company, MetLife Credit Corp.,
MetLife Funding, Inc., MetLife Group, Inc., MetLife Securities, Inc., MetLife
Bank, National Association and Texas Life Insurance Company, for whom all

Article 1 - Purpose of Plan

the Company's contribution to a deferred compensation plan to the extent such
contributions are not includible in the participant's gross income for the
taxable year in which contributed in determining a participant's compensation
under the Savings and Investment Plan, for purposes of Section 415(c) of the
Code.

and Casualty Insurance Company, MetLife Credit Corp., MetLife Funding, Inc.,

the Savings and Investment Plan who is enrolled to contribute 401(k) and/or
after-tax contributions to the Savings and Investment Plan during the Plan Year
equal to at least 3% of his or her compensation (as defined in the Savings and

<PAGE>

which the Participant, who has one or more years of continuous service, is
receiving disability benefits (including short-term and long-term disability)
from the Company's disability plans a continuous period of 24 months.

Article 3 - Participation

      Each participant in the Savings and Investment Plan whose compensation
exceeds the limitation of Section 401(a)(17) of the Code and whose Company
matching contributions under the Savings and Investment Plan are reduced or
eliminated because of the application of Section 1.415-2(d)(3)(i) of the
Treasury Regulations shall be a Participant under this Plan.

Article 4 - Vesting and Payment of Benefits

4.1 Company Contributions.

      (a) In General. Except as otherwise provided in subsection (b), for each
Plan Year, the Company shall contribute to this Plan, on behalf of each
Participant, the amount of Company matching contributions that would have been
made to the Savings and Investment Plan had the limitation of Section
1.415-2(d)(2) of the Treasury Regulations not applied to such Participant's
account under the Savings and Investment Plan.

      (b) Suspension for Savings and Investment Plan Withdrawals.
Notwithstanding subsection (a), no Company Contributions shall be made for the
six-month period beginning on the first day of the second month following the
date that the Participant receives (1) a hardship withdrawal of his or her
401(k) contributions under the provisions of the Savings and Investment Plan or
(2) a withdrawal of Company Contributions under the provisions of the Savings
and Investment Plan.

                                        3
<PAGE>

4.2. Vesting of Company Contributions. Company Contributions under this Plan
shall vest in accordance with the vesting schedule applicable to Company
matching contributions under the Savings and Investment Plan.

4.3. Elections and Tracking of Investment Performance. Subject to the Plan
Administrator's consent, a Participant may make an election with respect to the
investment allocation of future Company contributions as well as existing
balances. Such allocation shall be pegged to the performance of one or more of
the Core Funds set forth under the Savings and Investment Plan (other than the
MetLife Company Stock Fund and the NEF Frozen Accumulation Account). No
investment allocation election shall represent an actual investment in any such
fund, but shall merely reflect the performance of such fund. Thus, the
Participant's account balance under this Plan shall be adjusted for income,
gains and losses in the same manner as if such Participant had directed the
investment of his or her account balance among one or more of the aforementioned
funds under the Savings and Investment Plan. The Participant's ability to change
the investment allocation of future contributions and existing balances shall be
subject to the same rules and restrictions as apply under the Savings and
Investment Plan. If a Participant fails to specify the allocation of
contributions to this Plan, then earnings, gains and/or losses on such
contributions shall be determined using the returns from the Fixed Income Fund
until changed by the Participant, Beneficiary or alternate payee.
Notwithstanding the foregoing, it will be within the discretion of the Plan
Administrator whether contributions are actually invested according to each
Participant's stated preferences.

4.4. Participant's Election of Time and Form of Benefit Distributions.

                                        4
<PAGE>

      (a) In General. Except as otherwise provided in this Section, a
Participant may elect, subject to the consent of the Plan Administrator, the
form in which to receive distribution of his or her benefits and the time when
distribution of such benefits will commence. Subject to the approval of the Plan
Administrator, the Participant may elect to receive distribution of his or her
benefits under this Plan in the form of a single sum, installments payable over
a specified number of years or in any other form. Benefits shall commence no
earlier than the date on which the Participant has a Termination of Employment
(subject to the date on which the Participant made the election, as further
described in this subsection). The Participant may elect that the commencement
of benefits be deferred for a period that is approved by the Plan Administrator.
Such election shall be made as prescribed by the Plan Administrator and shall
require the Participant to designate the mode of payment requested and the
deferral period after which benefits will commence to be paid. Such election
shall be made no later than the date on which a Participant has a Termination of
Employment. Such election may be changed any number of times prior to the
Participant's Termination of Employment and each election shall invalidate all
preceding elections. If the Participant fails to make an election or the
Participant's election is ineffective for any reason, the Participant will be
deemed to have elected to receive his or her vested account balance in the form
of a single sum, payable as soon as reasonably practicable following the date on
which such Participant has a Termination of Employment. Benefits shall become
payable after the deferral period elected by the Participant which deferral
period shall not end earlier than the later of (i) twelve (12) months subsequent
to the date on which the Participant makes the election with the Plan
Administrator; and (ii) the date on which the Participant has a Termination of
Employment.

                                        5
<PAGE>

      (b) Cash-out of a Participant's Account Balance. If, as of the date of the
Participant's Termination of Employment or such other date which is established
by the Plan Administrator and communicated to the affected Participants, such
Participant's vested account balance does not exceed $20,000, such Participant's
vested account balance will be distributed in a single sum as soon as
administratively practicable following his or her death or Termination of
Employment, notwithstanding any election that such Participant may have made
under subsection (a) regarding the form and time of commencing distribution of
his or her vested account balance.

      (c) No In-Service Withdrawals or Loans. Notwithstanding any provision in
this Plan to the contrary, no benefits under this Plan will be eligible for any
in-service withdrawal by a Participant or any loans to a Participant.

      (d) Distributions after Participant's Death. At the time of the
Participant's death, regardless of whether benefits had commenced prior to the
date of the Participant's death and regardless of any previous election, except
that in the case where the Participant had elected an annuity form of
distribution and the Participant's account balance under this Plan was
annuitized prior to the Participant's death, then a single sum shall be paid to
the Participants's Beneficiary (determined in accordance with Section 4.5) as
soon as administratively practicable following the date on which the Plan
Administrator is duly notified of the Participant's death.

4.5 Beneficiary. Except as provided below, the Participant's Beneficiary shall
be the beneficiary designated by the Participant under the Savings and
Investment Plan. However, if the Participant filed a beneficiary designation
under this Plan, such designation shall supersede the Participant's beneficiary
designation under the Savings and Investment Plan and upon the

                                        6
<PAGE>

Participant's death, benefits shall be payable to the primary Beneficiary(ies)
designated under this Plan. If there is more than one beneficiary under the
Savings and Investment Plan or more than one primary Beneficiary under this Plan
and the beneficiary designation does not specify the percentage of the
Participant's benefit to be paid to each such Beneficiary, each Beneficiary
shall share equally in the benefits under the Plan. If one or more Beneficiaries
predecease the Participant, the surviving Beneficiary(ies) shall share equally
in the deceased Beneficiary's portion of the Plan benefits. If all primary
Beneficiaries predecease the Participant, benefits shall be payable to the
contingent Beneficiary(ies) upon the Participant's death. If there is more than
one contingent Beneficiary(ies), and the contingent Beneficiary designation does
not specify the percentage of the Participant's benefit to be paid to each such
Beneficiary, each contingent Beneficiary shall share equally in the benefits
under the Plan. If one or more contingent Beneficiaries predecease the
Participant, the surviving contingent Beneficiary(ies) shall share equally in
the deceased contingent Beneficiary's portion of the Plan benefits. If all
contingent Beneficiaries predecease the Participant, or if there is no
beneficiary designation in effect on the date of the Participant's death,
benefits will be payable to the Participant's surviving spouse or, in the
absence of such spouse, to the Participant's estate.

4.6. No Duplication of Benefits. Notwithstanding any provision in this Plan to
the contrary, no similar benefit that is paid under this Plan shall be paid
under any other deferred compensation plan(s) created by the Company or any of
its affiliates.

                                        7
<PAGE>

Article 5 - Unfunded Plan

      The Plan is completely unfunded, and payment of benefits is supported only
by the general assets of each Company. This Plan is entirely separate from the
Savings and Investment Plan and participation in this Plan gives a Participant
no right to any funds or assets of the Savings and Investment Plan. The fact
that contracts or certificates of the Company may be distributed to recipients
of benefits under the Savings and Investment Plan in discharge of the Company's
obligations thereunder shall in no way entitle a Participant in this Plan to
receive any such contract or certificate in discharge of the Company's
obligations hereunder.

Article 6 - Nontransferability of Participant's Interest

      No Participant shall have any power or right to transfer, assign,
mortgage, commute or otherwise encumber any of the benefits payable hereunder,
nor shall such benefits be subject to seizure for the payment of any debts or
judgments, or be transferable by operation of law in the event of bankruptcy,
insolvency or otherwise.

Article 7 - Effect of Taxes

      In making payments under this Plan, the Company shall withhold any
Federal, state or local income or other taxes it determines that it is legally
obligated to withhold. In the event the payments received by the Participant
result in greater tax burdens (whether income, estate or other tax burdens) than
they would if such payments had been able to be received under the Savings and
Investment Plan, the Company shall have no obligation to reimburse the
Participant for such greater tax burdens.

                                        8

Article 8 - Administration of the Plan

8.1. Plan Administrator's Interpretation Binding

      The Plan Administrator is empowered to take all actions it deems
appropriate in administering this Plan. In the event of a difference of opinion
between a Participant and the Plan Administrator with respect to the meaning or
application of the provisions of the Plan, the Plan Administrator's final
interpretation shall be set forth in writing to the Participant and shall be
binding and conclusive. However, once a Change of Control (as defined in Article
11) has occurred, this Article 8 shall no longer apply to differences of opinion
between the Plan Administrator and a Participant regarding the application of
Article 11 of this Plan to a Participant or with regard to any rights or
benefits protected under Article 11 of this Plan or otherwise accrued prior to
the Change of Control including the vesting thereof.

8.2. Claims and Review Procedure. Claims for benefits and appeals of denied
claims under the Plan shall be administered in accordance with Section 503 of
ERISA, the regulations thereunder (and any other law that amends, supplements or
supersedes said Section of ERISA), and the procedures adopted by the Plan
Administrator, or its delegate, as appropriate. The claims procedures referenced
above are incorporated herein by reference. The Plan shall provide adequate
notice to any claimant whose claim for benefits under the Plan has been denied,
setting forth the reasons for such denial, and afford a reasonable opportunity
to such claimant for a full and fair review by the Plan Administrator of the
decision denying the claim. Benefits will be paid under the Plan only if the
Plan Administrator, or its delegate, determines in its discretion that the
applicant is entitled to them.

                                        9
<PAGE>

Article 9 - Governing Law

      To the extent not inconsistent with Federal law, the validity of the Plan
and its provisions shall be construed according to the laws of the State of New
York.

Article 10 - Amendment and Termination of Plan

10.1 Amendment or Termination of the Plan. Except to the extent required by law,
the Plan Administrator may amend or terminate this Plan at any time without the
consent of any Participant or of any other person. However, any such amendment
will not affect adversely the benefit entitlements of:

     (a)  Any Participant receiving benefits under the Plan at or prior to the
          time of such amendment or termination, or

     (b)  Any employee who is a Participant in the Savings and Investment Plan
          to the extent of the account balance under this Plan prior to the time
          of such amendment or termination. However, amendments may be made to
          all other aspects of this Plan including, but not limited to:

            (i)   amendments impacting the timing under which the Participant's
                  entire account balance is paid, or,

            (ii)  amendments impacting the optional forms of distributions for
                  payment of the Participant's entire account.

      Notwithstanding the above, any amendment or group of amendments made
effective on the same date, which would increase or decrease the annual cost of
Plan benefits for active Plan Participants and former Plan Participants by ten
million dollars or more in the aggregate, as

                                       10
<PAGE>

determined in good faith by the Plan Administrator, shall take effect only after
the action is authorized or ratified by the Board of Directors of Metropolitan
Life Insurance Company.

10.2 Effect of Change of Control. Notwithstanding the provisions of Section 10.1
above, or any other provision of this Plan, on or after a Change of Control (as
defined in Article 11),

      (a) amendments can no longer be made to or have any impact upon Article 8,
          Section 10.2 of Article 10 or Article 11 of this Plan; and

      (b) Participants who:

            (i) accrued rights or benefits under this Plan prior to a Change of
      Control (as defined in Article 11), and,

            (ii) whose rights or benefits are not vested at the time of the
      Change of Control cannot have the vesting schedule under Section 4.2,
      applicable on the day prior to the Change of Control, amended with regard
      to such rights or benefits, and cannot forfeit, or be deprived of, their
      right to vest in these accrued benefits due to any amendment or
      termination of this Plan.

            of the Board of Directors of the Corporation (the "Board") or the
            board of directors of any successor to the Corporation; provided,
            however, that any director elected or nominated for election to the
            Board by a majority of the Incumbent Directors then still in office
            shall be deemed to be an Incumbent Director for purposes of this
            Section 11.1(a)(ii);

                  (iii) the stockholders of the Corporation approve a merger,

            to such Corporate Event; or
