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


     2.01  Purpose.  The purpose of this Plan is (1) to provide the "Beef-up"
           -------
benefit for eligible employees as described in Section 3.02(b), and (2) to make
up lost early retirement payments for individuals who failed to reach their 20th
anniversary with Allstate as described in Section 3.01(b). The Plan is an
unfunded deferred compensation program for a select group of management and


highly compensated employees. Thus, the Plan is subject to Part 1 of Title I of
ERISA, but is exempt from Parts 2, 3 and 4 thereof.

     2.02  Administration.  The Plan will be administered by the Committee. The
           --------------
Committee has all discretionary authority to issue such rules as it deems
appropriate and to interpret the provisions of the Plan and make factual
determinations, including the power to determine the rights or eligibility of
employees or participants and any other persons, and the amounts of their
benefits under the Plan, and to remedy ambiguities, inconsistencies, or
omissions. Any decision by the Committee shall be final, binding, and conclusive
on all participants and all other persons.

                                  ARTICLE III
                                  -----------

                      ELIGIBILITY AND AMOUNT OF BENEFITS
                      ----------------------------------


     3.01  Eligibility.  Each employee of an Employer who meets the definition
           -----------
of Section 1.04(a) and 1.04(b) is eligible to receive a benefit under this Plan
if he or she is vested in benefits under the Retirement Plan and if:

           (a)  he or she is eligible for the "Beef-up" as described in the
Allstate Retirement Plan Document in effect on April 1, 1995; or

           (b)  he or she (i) has less than 20 years of service with Allstate on
April 1, 1995, (ii) retires from the Company with at least 20 years of total
service with the Company and Allstate combined, and (iii) has reached his or her
55th birthday but has not reached his or her normal retirement date as defined
by the Allstate Retirement Plan.

     3.02  Amount of Benefit.  The amount of benefit paid from the Plan will be
           -----------------
equal to: (a) plus (b) minus (c) below:

           (a)  For Participants who retire from the Retirement Plan before
     December 31, 1999 and who are at least age 55 but less than age 60, the
     Company will enhance their benefit as described in (i) and (ii) below:

                (i)  The Participant's Final Average Compensation will be
     calculated as if he or she had continued to work until the earlier of
     December 31, 1999 or age 60 at their current pensionable earnings. If the
     Final Average Compensation is greater when calculated in this manner, it
     will be used in place of the Final Average Compensation calculated in the
     normal manner at termination.

                (ii) For Participants who were hired at Allstate before 1978,
     his or her benefit will be first decreased by (A) below and then increased
     by (B) below:

                                      -2-


                      (A)  The number of years from termination to the latter of
December 31, 1999 or age 60 divided by the number of years of Allstate service
prior to January 1, 1978 times the Allstate pre-1978 benefit.

                      (B)  The number of years from termination to the latter of
December 31, 1999 or age 60 divided by the number of years of service from
January 1, 1988 to April 1, 1995 times the Allstate post-1988 benefit.

           (b)  For Participants who retire from the Retirement Plan with at
least 55 years of age and 20 years of combined service with the Company and
Allstate and who did not have 20 years of service with Allstate on April 1,
1995, the Company will provide a temporary annuity equal to: (i) as reduced in
(ii) payable for the period described in (iii) below:

                (i)   The monthly life annuity payable from the Allstate
Retirement Plan starting at the Participant's Normal Retirement Date as
described by the Allstate Retirement Plan. This is the accrued Allstate benefit
at the Company spin-off date as communicated by Allstate.

                (ii)  The monthly life annuity will be reduced by one half
percent per month (6% per year) for each month the Participant's retirement
precedes his or her Normal Retirement as described by the Allstate Retirement
Plan.

                (iii) The monthly life annuity will be paid starting on the
first day of the month following retirement until the earlier of the
Participant's death or the date which the Participant becomes eligible to
receive his or her benefit from the Allstate Retirement Plan. Alternatively, the
Participant may elect to have, in the event of his or her death, the monthly
life annuity continue to his or her surviving Spouse but not beyond the date
when the Participant would have become eligible to receive his or her benefit
from the Allstate Retirement Plan. If the Participant elects to have the full
benefit continue to his or her Spouse, then the benefit in 3.02(b)(ii) above
will be further reduced two percent. If the Participant elects to have half of
the benefit continue to his or her Spouse, then the benefit in 3.02(b)(ii) above
will be further reduced one percent.

           (c)  The amount of benefit payable from the Retirement Plan.

     3.03  Preretirement Surviving Spouse Benefit.  Preretirement Surviving
           --------------------------------------
Spouse Benefits will be payable under this Plan on behalf of a Participant if
such Participant's surviving Spouse is eligible for benefits payable from the
Retirement Plan. The benefit payable will be determined in a manner consistent
with similar benefits under the Retirement Plan.

     3.04  Death Benefits After Retirement.  Benefits will be payable from this
           -------------------------------
Plan to a beneficiary or contingent annuitant designated by a Retired
Participant only if such beneficiary or contingent annuitant will also receive
benefits from the Retirement Plan after such Participant's death. The amount of
the benefit payable will be determined in a manner consistent with similar
benefits under the Retirement Plan.

                                      -3-


                                  ARTICLE IV
                                  ----------

                              PAYMENT OF BENEFITS
                              -------------------


     4.01  Forms and Timing of Benefit Payments.  All benefits except those
           ------------------------------------
described in 3.02(b) above, at the Participant's election (a) will be paid as a
single lump sum based on the life annuity at the time the Participant terminates
or retires, or (b) an annuity form of payment permitted under the terms of the
Retirement Plan. A Participant's election as to the form of payment shall be
irrevocable and must be made while the Participant is an employee and at least
twelve months prior to payment under the Plan. The Retirement Plan factors for
calculating the Participant's payment under the Plan in effect at the time of
termination or retirement will be used to calculate such payment .

     4.02  Plan Termination.  No further benefits may be earned under this Plan
           ----------------
with respect to the Retirement Plan after the termination of the Retirement
Plan.

     4.03  Facility of Payment.  Any amount payable under the Plan to a person
           -------------------
under legal disability or who, in the judgment of the Committee, is unable to
properly manage his financial affairs, may be paid to such person's legal
representative, or may be applied for the benefit of such person in any manner
selected by the Committee.

     4.04  Review of Benefit Determinations.  The Committee will provide notice
           --------------------------------
in writing to any Participant or Beneficiary whose claim for benefits under the
Plan is denied and the Committee shall afford such Participant or Beneficiary a
review of its decision if so requested.

     4.05  Payment and Funding of Benefits.  Amounts payable under the Plan to
           -------------------------------
or on account of a Participant shall be paid directly by the Employers, and
shall be provided solely from the general assets of the Employers. Benefits
under the Plan are not funded, the Employers' obligation to pay such benefits is
merely an unsecured contractual obligation, and a Participant or Beneficiary
shall be treated as a general creditor of the Employers with respect to any
benefits payable under the Plan. Except as provided in Section 4.06, nothing in
this Plan shall be deemed to create a trust of any kind for the benefit of the
Participant or any beneficiary, or create any fiduciary relationship between the
Company and the Participant or any beneficiary with respect to any assets of the
Company.

     4.06  Contributions to Trust Upon a Change of Control.  Upon a "Change of
           -----------------------------------------------
Control" (as defined below) and by the fifteenth business day following the end
of each calendar month of each Plan year thereafter, the Employer shall
irrevocably deposit cash (or its equivalent) to a Trust for the investment of
benefits payable under the Plan to or on account of each Participant. However,
any contributions made to the Trust in respect of each Participant shall remain
subject to the claims of the general creditors of the Employers. Nothing
contained in this Section 4.06 shall give any Participant or beneficiary any
interest in or claim against any specific assets of the Company. For purposes of
this Plan, "Change of Control" shall mean:

                                      -4-


          (a)  The acquisition by any individual, entity or group (within the
meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934,
as amended (the "Exchange Act")) (a "Person") of beneficial ownership (within
the meaning of Rule 13d-3 promulgated under the Exchange Act) of 20% or more of
either (i) the then outstanding shares of common stock of the Company (the
"Outstanding Company Common Stock") or (ii) the combined voting power of the
then outstanding voting securities of the Company entitled to vote generally in
the election of directors (the "Outstanding Company Voting Securities");
provided, however, that for purposes of this subsection (a), the following shall
not constitute a Change of Control: (i) any acquisition directly from the
Company, (ii) any acquisition by the Company, (iii) any acquisition by any
employee benefit plan (or related trust) sponsored or maintained by the Company
or any corporation controlled by the Company, (iv) any beneficial ownership
maintained by (but not additional acquisitions by), The Allstate Corporation and
its subsidiaries, and their respective successors ("Allstate"), pending such
time that Allstate distributes or transfers its current ownership interest in
the Outstanding Company Common Stock and Outstanding Company Voting Securities
as contemplated by the Prospectus dated April 10, 1995, relating to the initial
public offering of the common stock of the Company, or (v) any acquisition
pursuant to a transaction which complies with clauses (i), (ii) and (iii) of
subsection (c) of this Section 4.06. Notwithstanding the foregoing, in its sole
discretion, the Board may increase the 20% threshold set forth above in this
subsection (a) prior to any acquisition of 20% or more beneficial ownership of
the Outstanding Company Common Stock or the Outstanding Company Voting
Securities; provided, that (i) such increased threshold shall apply only to the
acquisition and maintenance of beneficial ownership by any Person eligible to
report such beneficial ownership at the time of such acquisition on Schedule 13G
under the Exchange Act, and (ii) in the event that any Person initially eligible
to so report on Schedule 13G thereafter ceases to be eligible to so report on
Schedule 13G, the occurrence of the event causing such Person no longer to be
eligible to so report shall be deemed an acquisition by such Person of all of
the Outstanding Company Common Stock and Outstanding Company Voting Securities
beneficially owned by such Person immediately prior to such occurrence; or

          (b)  Individuals who, as of the date hereof, constitute the Board (the
"Incumbent Board") cease for any reason to constitute at least a majority of the
Board; provided, however, that any individual becoming a director subsequent to
the date hereof whose election, or nomination for election by the Company's
shareholders, was approved by a vote of at least a majority of the directors
then comprising the Incumbent Board shall be considered as though such
individual were a member of the Incumbent Board, but excluding, for this
purpose, any such individual whose initial assumption of office occurs as a
result of an actual or threatened election contest with respect to the election
or removal of directors or other actual or threatened solicitation of proxies or
consents by or on behalf of a Person other than the Board; or

          (c)  Consummation by the Company of a reorganization, merger or
consolidation or sale or other disposition of all or substantially all of the
assets of the Company or the acquisition of assets of another entity (a
"Business Combination"), in each case, unless, following such Business
Combination, (i) all or substantially all of the individuals and entities who
were the beneficial owners, respectively, of the Outstanding Company Common
Stock and Outstanding Company Voting Securities immediately prior to such
Business Combination beneficially own, directly or

                                      -5-


indirectly, more than 60% of, respectively, the then outstanding shares of
common stock and the combined voting power of the then outstanding voting
securities entitled to vote generally in the election of directors, as the case
may be, of the corporation resulting from such Business Combination (including,
without limitation, a corporation which as a result of such transaction owns the
Company or all or substantially all of the Company's assets either directly or
through one or more subsidiaries) in substantially the same proportions as their
ownership, immediately prior to such Business Combination of the Outstanding
Company Common Stock and Outstanding Company Voting Securities, as the case may
be, (ii) no Person (excluding any employee benefit plan (or related trust) of
the Company or such corporation resulting from such Business Combination)
beneficially owns, directly or indirectly, 20% or more of, respectively, the
then outstanding shares of common stock of the corporation resulting from such
Business Combination or the combined voting power of the then outstanding voting
securities of such corporation except to the extent that such ownership existed
prior to the Business Combination and (iii) at least a majority of the members
of the board of directors of the corporation resulting from such Business
Combination were members of the Incumbent Board at the time of the execution of
the initial agreement, or of the action of the Board, providing for such
Business Combination; or

            (d)  Approval by the shareholders of the Company of a complete
liquidation or dissolution of the Company.

     Notwithstanding the foregoing, a Change of Control shall not be deemed to
occur solely because any Person acquires beneficial ownership of 20% or more of
the Outstanding Company Voting Securities or Outstanding Company Common Stock as
a result of the acquisition of such securities or stock by the Company, which
acquisition reduces the number of the Outstanding Company Voting Securities or
Outstanding Company Common Stock; provided, that if after such acquisition by
the Company such Person (while such Person remains the beneficial owner of 20%
or more of the Outstanding Company Voting Securities or Outstanding Company
Common Stock) becomes the beneficial owner of additional shares of such
Outstanding Company Voting Securities or Outstanding Company Common Stock (as
the case may be), a Change of Control shall then occur.  Capitalized terms used
in this Section 4.06, not otherwise defined, shall have the meaning set forth in
the form of change of control employment agreement approved at the February 12,
1998 meeting of the Board of Directors.

                                   ARTICLE V
                                   ---------

                                 MISCELLANEOUS
                                 -------------


     5.01   Action by Company.  Any action required or permitted to be taken by
            -----------------
the Company under the Plan shall be by resolution of its Board of Directors, by
resolution of a duly authorized committee of its Board of Directors, or by a
person or persons authorized by resolution of its Board of Directors or such
committee.

     5.02   Amendment and Plan Termination.  The Company may, in its sole
            ------------------------------
discretion, terminate, suspend, or amend this Plan at any time or from time to
time, in whole or in part, but no

                                      -6-


amendment, suspension, or termination of the Plan shall, without the consent of
a Participant, reduce the accrued benefit of the Participant or any Spouse.

     5.03  No Effect on Employment.  Nothing in the Plan shall interfere with or
           -----------------------
limit in any way the right of the Company or the Employer directly employing the
Participant to terminate any Participant's employment at any time, with or
without cause. Employment with the Company and its affiliates is on an at- will
basis only.

     5.04  Assignment of Benefits.  A Participant, Retired Participant,
           ----------------------
surviving Spouse, or beneficiary may not, either voluntarily or involuntarily,
assign, anticipate, alienate, commute, pledge, or encumber any benefits to which
he or she is or may become entitled under the Plan, nor may the same be subject
to attachment or garnishment by any creditor's claim or to legal process.

     5.05  Construction.  The Committee shall have full discretionary authority
           ------------
to determine eligibility and to construe and interpret the terms of the Plan,
including the power to remedy possible ambiguities, inconsistencies, or
omissions.

     5.06  Governing Law; Severability.  The Plan shall be construed,
           ---------------------------
administered and governed in all respects in accordance with the laws of the
State of California (but without giving effect to any choice or conflict of law,
provision or rule which would cause the application of the laws of any
jurisdiction other than the State of California), and, to the extent applicable,
ERISA and the Code. If any provision of the Plan shall be held invalid or
unenforceable by a court of competent jurisdiction, the remaining provisions
hereof shall continue to be fully effective.

     5.07  Number.  The singular, where appearing in this Plan, will be deemed
           ------
to include the plural, unless the context clearly indicates the contrary.

     5.08  Participation of Affiliates.  One or more affiliates of the Company
           ---------------------------
may become participating employers by adopting the Plan. By adopting the Plan,
an affiliate is deemed to agree to all of its terms, including (but not limited
to) the provisions granting exclusive authority to the Company to amend the Plan
and the provisions granting exclusive authority to the Committee to administer
and interpret the Plan. Any affiliate may terminate its participation in the
Plan at any time subject, in each case, to the approval of the Company. The
liabilities incurred under the Plan to the Participants employed by each
employer shall be solely the liabilities of that employer, and no other employer
shall be liable for benefits accrued by a Participant during any period when he
or she was not employed by such employer.

     5.09  Indemnification.  The Company shall, and hereby does, indemnify and
           ---------------
hold harmless the members of the Committee, from and against any and all losses,
claims, damages or liabilities (including attorneys' fees and amounts paid, with
the approval of the Company's Board of Directors, in settlement of any claim)
arising out of or resulting from the implementation of a duty, act or decision
with respect to the Plan, so long as such duty, act or decision does not involve
gross negligence or willful misconduct on the part of any such individual.
