                          NOTES TO FINANCIAL STATEMENTS

1.   Basis of Presentation

          The accompanying financial statements include the accounts of
     Glenbrook Life and Annuity Company (the "Company"), a wholly owned
     subsidiary of Allstate Life Insurance Company ("ALIC"), which is wholly
     owned by Allstate Insurance Company ("AIC"), a wholly owned subsidiary of
     The Allstate Corporation (the "Corporation").

          The financial statements and notes as of March 31, 2001 and for the
     three month periods ended March 31, 2001 and 2000 are unaudited. The
     interim financial statements reflect all adjustments (consisting only of
     normal recurring accruals) which are, in the opinion of management,
     necessary for the fair presentation of the financial position, results of
     operations and cash flows for the interim periods. These financial
     statements and notes should be read in conjunction with the financial
     statements and notes thereto included in the Glenbrook Life and Annuity
     Company Annual Report on Form 10-K for 2000. The results of operations for
     the interim periods should not be considered indicative of results to be
     expected for the full year.


2.   Reinsurance

          The Company has reinsurance agreements whereby all contract charges,
     credited interest, policy benefits and certain expenses are ceded to ALIC
     and reflected net of such reinsurance in the statements of operations.
     Reinsurance recoverable and the related Reserve for life-contingent
     contract benefits and Contractholder funds are reported separately in the
     statements of financial position. The Company continues to have primary
     liability as the direct insurer for risks reinsured.

          Investment income earned on the assets which support Contractholder
     funds and the Reserve for life life-contingent contract benefits is not
     included in the Company's financial statements as those assets are owned
     and managed under the terms of reinsurance agreements.

          The following table summarizes amounts ceded to ALIC under reinsurance
     agreements.

4.   Regulation and Legal Proceedings

          The Company's business is subject to the effects of a changing social,
     economic and regulatory environment. Recent state and federal regulatory
     initiatives have varied, and have included employee benefit regulations,
     removal of barriers preventing banks from engaging in the securities and
     insurance business, tax law changes affecting the taxation of insurance
     companies, the tax treatment of insurance products and its impact on the
     relative desirability of various personal investment vehicles, proposed
     legislation to prohibit the use of gender in determining insurance rates
     and benefits and the overall expansion of regulation. The ultimate changes
     and eventual effects, if any, of these initiatives are uncertain.

          In the normal course of its business, the Company is involved from
     time to time in pending and threatened litigation and regulatory actions in
     which claims for monetary damages are asserted. Regulatory actions include,
     but are not limited to, market conduct and compliance issues. At this time,
     based on the present status of such litigation and regulatory actions, it
     is in the opinion of management that the ultimate liability, if any, in one
     or more of these matters in excess of amounts currently reserved is not
     expected to have a material adverse effect on the results of operations,
     liquidity or financial position of the Company.

5.   Third Party Administration Agreement

          On January 2, 2001, the Company entered into an administrative
     services agreement with American Maturity Life Insurance Company ("American
     Maturity") to administer certain blocks of annuities that American Maturity
     reinsures to ALIC. Pursuant to the terms of the agreement, the Company is
     to provide insurance contract administration and financial services,
     effective January 15, 2001, for all contracts covered under the reinsurance
     agreement. The Company utilizes services performed by AIC and ALIC and
     business facilities owned or leased, and operated by AIC in conducting
     these activities. The administrative services agreement can be terminated
     by either the Company or American Maturity upon mutual consent or as
     otherwise provided for in the terms of the agreement. During the first
     three months of 2001, the Company earned administration fees of $29
     thousand and incurred $21 thousand in related expenses.

        FINANCIAL CONDITION AND RESULTS OF OPERATIONS FOR THE THREE MONTH
                      PERIODS ENDED MARCH 31, 2001 AND 2000

     The following discussion highlights significant factors influencing results
of operations and changes in financial position of Glenbrook Life and Annuity
Company (the "Company"). It should be read in conjunction with the financial
statements and related notes thereto found under Part I Item 1 contained herein,
and with the discussion, analysis, financial statements and notes thereto in
Part I Item 1 and Part II Items 7 and 8 of the Glenbrook Life and Annuity
Company Annual Report on Form 10-K for the year ended December 31, 2000.

OVERVIEW

     The Company, a wholly owned subsidiary of ALIC, which is a wholly owned
subsidiary of AIC, a wholly owned subsidiary of the Corporation, markets
investment and life insurance products through banks and securities firms.
Investment products include deferred annuities and immediate annuities without
life contingencies. Deferred annuities include fixed rate, market value
adjusted, indexed and variable annuities. Life insurance consists of
interest-sensitive life and variable life insurance.

      The Company has identified itself as a single segment entity.

      The assets and liabilities related to variable annuity and variable life
contracts are legally segregated and reflected as Separate Accounts. The assets
of the Separate Accounts are carried at fair value. Separate Accounts
liabilities represent the contractholders' claim to the related assets and are
carried at the fair value of the assets. In the event that the asset value of
certain contractholder accounts are projected to be below the value guaranteed
by the Company, a liability is established through a charge to earnings.
Investment income and realized capital gains and losses of the Separate Accounts
accrue directly to the contractholders and therefore, are not included in the
Company's statements of operations.

operations include Net investment income and Realized capital gains and losses
earned on the assets of the Company that are not transferred under the
reinsurance agreements. Also included in the results of operations are
Administration fees earned and expenses incurred resulting from the third party
administration agreement, as described in Note 5.

                   ITEM 2. MANAGEMENT DISCUSSION AND ANALYSIS OF
        FINANCIAL CONDITION AND RESULTS OF OPERATIONS FOR THE THREE MONTH
                      PERIODS ENDED MARCH 31, 2001 AND 2000

     Net income for the first quarter of 2001 increased 3.0% to $1.8 million,
due to increased net investment income partially offset by realized capital
losses. Net investment income for the three month period ended March 31, 2001
increased 7.1% to $2.7 million attributable to higher investment balances while
yields were comparable in both periods. Investments at March 31, 2001, excluding
unrealized gains and losses on fixed income securities, grew 4.6% as compared to
March 31, 2000.

     Realized capital losses, after-tax, were $30 thousand for the three month
periods ended March 31, 2001 compared to realized capital gains of $43 thousand,
after-tax, for the same period last year. Period to period fluctuations in
realized capital gains and losses are largely the result of the timing of sales
decisions reflecting management's decisions on positioning the portfolio, as
well as valuation assessments of individual securities and overall market
conditions.

(1) Fixed income securities are carried at fair value. Amortized cost for these
securities was $142,790 and $139,819 at March 31, 2001 and December 31, 2000,
respectively.

     Total investments were $162.3 million at March 31, 2001 compared to $147.2
million at December 31, 2000. The increase was primarily due to investment of
cash on hand as well as positive cash flows generated from operations and higher
unrealized net capital gains on fixed income securities. Investments at March
31, 2001, excluding unrealized gains on fixed income securities, and cash grew
1.3% from December 31, 2000.

     At March 31, 2001, substantially all of the Company's fixed income
securities portfolio is rated investment grade, which is defined by the Company
as a security having a National Association of Insurance Commissioners ("NAIC")
rating of 1 or 2, a Moody's rating of Aaa, Aa, A or Baa, or a comparable Company
internal rating.

     During the three months ended March 31, 2001, Contractholder funds and
Reinsurance recoverable from ALIC increased by $201.9 million and $202.2
million, respectively. The increase resulted from sales of the Company's fixed
rate annuity contracts, partially offset by surrenders and withdrawals on fixed
rate annuity contracts. Reinsurance recoverable from ALIC relates to contract
benefit obligations ceded to ALIC.

     Separate Account assets and liabilities decreased 12.6% to $1.52 billion at
March 31, 2001. The decreases were primarily attributable to unrealized losses
in the Separate Accounts investment portfolios and surrenders and withdrawals,
that were only partially offset by sales of variable annuity contracts and
transfers from the fixed account contract option to variable Separate Accounts
funds.

CAPITAL RESOURCES AND LIQUIDITY

     Under the terms of reinsurance agreements, substantially all premiums and
deposits, excluding those relating to Separate Accounts, are transferred to
ALIC, which maintains the investment portfolios supporting the Company's
products. Substantially all payments of policyholder claims, benefits, contract
maturities, contract surrenders and withdrawals and certain operating costs are
also reimbursed by ALIC under the terms of the reinsurance agreements. The
Company continues to have primary liability as a direct insurer for risks
reinsured. The Company's ability to meet liquidity demands is dependent on
ALIC's ability to meet its obligations under the reinsurance agreements. ALIC's
financial strength was rated Aa2, AA+ and A+ by Moody's, Standard and Poor's and
A.M. Best, respectively, at March 31, 2001.

     The primary sources for the remainder of the Company's funds are collection
of principal and interest from the investment portfolio and capital
contributions from ALIC. The primary uses for the remainder of the Company's
funds are to purchase investments and pay costs associated with the maintenance
of the Company's investment portfolio and pay dividends to ALIC.

     At March 31, 2001, the Moody's, Standard and Poor's and A.M. Best financial
strength ratings for the Company were Aa2, AA+ and A+, respectively.


FORWARD LOOKING STATEMENTS AND RISK FACTORS

     This document contains "forward-looking statements" that anticipate results
based on management's plans that are subject to uncertainty. These statements
are made subject to the safe-harbor provisions of the Private Securities
Litigation Reform Act of 1995.

     Forward-looking statements do not relate strictly to historical or current
facts and may be identified by their use of words like "plans," "expects,"
"will," "anticipates," "estimates," "intends," "believes," "likely" and other
words with similar meanings. These statements may address, among other things,
our strategy for growth, product development, regulatory approvals, market
position, expenses, financial results and reserves. Forward-looking statements
are based on management's current expectations of future events. We cannot
guarantee that any forward-looking statement will be accurate. However, we
believe that our forward-looking statements are based on reasonable, current
expectations and assumptions. We assume no obligation to update any
forward-looking statements as a result of new information or future events or
developments.

     If the expectations or assumptions underlying our forward-looking
statements prove inaccurate or if risks or uncertainties arise, actual results
could differ materially from those communicated in our forward-looking
statements. In addition to the normal risks of business, the Company is subject
to significant risk factors, including those listed below which apply to it as
an insurance business.

o    There is uncertainty involved in estimating the availability of reinsurance
     and the collectibility of reinsurance recoverables. This uncertainty arises
     from a number of factors, including the restructuring by reinsurers of
     their capital structures and segregation by the industry generally of
     reinsurance exposure into separate legal entities with dedicated capital.

                                       11

                  ITEM 2. MANAGEMENT DISCUSSION AND ANALYSIS OF
        FINANCIAL CONDITION AND RESULTS OF OPERATIONS FOR THE THREE MONTH
                      PERIODS ENDED MARCH 31, 2001 AND 2000

o    Changes in market interest rates can have adverse effects on the Company's
     investment portfolio, investment income, product sales and results of
     operations. Increasing market interest rates have an adverse impact on the
     value of the investment portfolio by decreasing unrealized capital gains on
     fixed income securities. Declining market interest rates could have an
     adverse impact on the Company's investment income as the Company reinvests
     proceeds from positive cash flows from operations and from maturing and
     called investments into new investments that could be yielding less than
     the portfolio's average rate. Changes in market rates of interest as
     compared to rates offered on some of the Company's products could make
     those products less attractive if competitive investment margins are not
     maintained. This could lead to lower sales and/or changes in the level of
     surrenders on these products. The Company seeks to limit its exposure in
     this area by offering a diverse group of products, periodically reviewing
     and revising crediting rates and providing surrender charges in the event
     of early withdrawal.

o    The impact of decreasing Separate Accounts balances as a result of
     fluctuating market conditions could cause contract charges ceded by the
     Company to decrease.

o    In order to manage interest rate risk, from time to time the effective
     duration of the assets and liabilities of the investment portfolio is
     adjusted. Those adjustments may have an impact on the value of the
     investment portfolio and on investment income.

o    Management believes the reserves for life-contingent contract benefits are
     adequate to cover ultimate policy benefits, despite the underlying risks
     and uncertainties associated with their determination when payments will
     not occur until well into the future. The Company periodically reviews and
     revises its estimates. If future experience differs from assumptions, it
     may have a material impact on results of operations.

o    Deferred annuities and interest-sensitive life insurance products receive
     favorable policyholder taxation under current tax laws and regulations. Any
     legislative or regulatory changes that adversely alter this treatment are
     likely to negatively affect the demand for these products. Additionally,
     the demand for life insurance products which are used to address a
     customer's estate planning needs may be impacted to the extent any
     legislative changes to the current estate tax laws occur.

o    The Company distributes some of its products under agreements with other
     members of the financial services industry that are not affiliated with the
     Company. Termination of one or more of these agreements due to changes in
     control or other factors of any of these entities could have a detrimental
     effect on the Company's sales. This risk may be exacerbated by the
     enactment of the Gramm-Leach-Bliley Act of 1999, which eliminates many
     federal and state law barriers to affiliations among banks, securities
     firms, insurers and other financial service providers.

o    Financial strength ratings have become an increasingly important factor in
     establishing the competitive position of insurance companies and,
     generally, may be expected to have an effect on an insurance company's
     sales. On an ongoing basis, rating agencies review the financial
     performance and condition of insurers. A downgrade, while not expected,
     could have a material adverse effect on the Company's or ALIC's business,
     financial condition and results of operations.

o    State insurance regulatory authorities require insurance companies to
     maintain specified levels of statutory capital and surplus. In addition,
     competitive pressures require the Company to maintain financial strength
     ratings. These restrictions affect the Company's ability to use its
     capital.

                                       12


o    A number of enacted and pending legislative measures could lead to
     increased consolidation and increased competition for business and for
     capital in the financial services industry.

     o    At the federal level, these measures include the recently enacted
          Gramm-Leach-Bliley Act of 1999, which eliminates many federal and
          state law barriers to affiliations among banks, securities firms,
          insurers and other financial service providers.

     o    At the state level, these measures include legislation to permit
          mutual insurance companies to convert to a hybrid structure known as a
          mutual holding company, thereby allowing insurance companies owned by
          their policyholders to become stock insurance companies owned (through
          one or more intermediate holding companies) partially by their
          policyholders and partially by stockholders. Also several large mutual
          life insurers have used or are expected to use existing state laws and
          regulations governing the conversion of mutual insurance companies
          into stock insurance companies (demutualization).

     o    In addition, state insurance regulators are reexamining the regulatory
          framework that currently governs the United States insurance business.
          They are engaged in an effort to determine the proper role of the
          state insurance regulation in the United States financial services
          industry following the enactment of the Graham-Leach-Bliley Act. The
          Company cannot predict whether any state or federal measures will be
          adopted to change the nature or scope of the regulation of the
          insurance business or what effect any such measures would have on the
          Company.

                      PART II - OTHER INFORMATION



Item 1.  LEGAL PROCEEDINGS

     The Company and its Board of Directors know of no material legal
     proceedings pending to which the Company is a party or which would
     materially affect the Company. The Company is involved in pending and
     threatened litigation in the normal course of its business in which claims
     for monetary damages are asserted. Management, after consultation with
     legal counsel, does not anticipate the ultimate liability arising from such
     pending or threatened litigation to have a material effect on the financial
     condition of the Company.
