NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

                            THE SIERRA VARIABLE TRUST

1.    ORGANIZATION AND BUSINESS

The Sierra Variable Trust (the "Trust") was organized under the laws of the
Commonwealth of Massachusetts on January 29, 1993 as a business entity commonly
known as a "Massachusetts business trust". The Trust is registered under the
Investment Company Act of 1940, as amended (the "1940 Act"), as a no-load,
open-end management investment company. The Trust offers fourteen managed
investment funds, consisting of nine funds: the Global Money Fund (the "Money
Fund"); the Short Term High Quality Bond, Short Term Global Government, U.S.
Government and Corporate Income Funds (the "Bond Funds"); the Growth and Income,
Growth, Emerging Growth and International Growth Funds (the "Equity Funds");
(collectively the "Funds" or "Underlying Funds") and five portfolios: Capital
Growth, Growth, Balanced, Value and Income Portfolios (individually a
"Portfolio" and collectively the "Portfolios"), to the public through certain
variable annuity contracts offered by American General Life Insurance Company
("AG Life"). Through investment in the Underlying Funds, the Portfolios offer a
range of asset allocation strategies designed to accommodate different
investment philosophies and goals. Information presented in these financial
statements pertains only to the Capital Growth, Growth and Balanced Portfolios.

Each Portfolio of the Trust invests, within predetermined percentage ranges, in
up to nine of the Underlying Funds of the Trust. In order to achieve its
investment objective, each Portfolio typically allocates its assets, within
determined percentage ranges, among certain of the Underlying Funds. The
percentages reflect the extent to which each Portfolio will invest in the
particular market segment represented by each Underlying Fund, and the varying
degrees of potential investment risk and reward represented by each Portfolio's
investments in those market segments and their corresponding Underlying Funds.
Sierra Investment Services Corporation ("Sierra Services") may alter these
percentage ranges when it deems appropriate. The assets of each Portfolio will
be allocated among the Underlying Funds in accordance with its investment
objective, Sierra Services' outlook for the economy and the financial markets
and the relative market valuations of the Underlying Funds. In addition,
generally in order to meet liquidity needs or for temporary defensive purposes,
each Portfolio may invest its assets directly in cash, stock or bond index
futures, options, money market securities and certain short-term debt
instruments.

2.    SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates. The following is a summary of
significant accounting policies consistently followed by the Portfolios in the
preparation of their financial statements.

PORTFOLIO VALUATION:

The Portfolios are valued at their net asset value per share of each Underlying
Fund determined as of the close of the New York Stock Exchange on the valuation
date. Short term investments that mature in 60 days or less are valued at
amortized cost when the Board of Trustees determines that this constitutes fair
value.

REPURCHASE AGREEMENTS:

Each Portfolio may engage in repurchase agreement transactions. Under the terms
of a typical repurchase agreement, the Portfolio, through its custodian, takes
possession of an underlying debt obligation subject to an obligation of the
seller to repurchase, and the Portfolio to resell, the obligation at an agreed
upon price and time, thereby determining the yield during the Portfolio's
holding period. This arrangement results in a fixed rate of return that is not
subject to market fluctuations during the Portfolio's holding period. The value
of the collateral is at least equal at all times to the total amount of the
repurchase obligation, including interest. In the event of counterparty default,
the Portfolio has the right to use the collateral to offset losses incurred.
There is potential loss to the Portfolio in the event the Portfolio is delayed
or prevented from exercising its right to dispose of the collateral securities,
including the risk of a possible decline in the value of the underlying
securities during the period while the Portfolio seeks to assert its rights.
Sierra Services, the Portfolios' investment advisor, acting under the
supervision of the Board of Trustees, reviews the value of the collateral and
the creditworthiness of those banks and dealers with which the Portfolio enters
into repurchase agreements to evaluate potential risks.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)

                           THE SIERRA VARIABLE TRUST

SECURITIES TRANSACTIONS AND INVESTMENT INCOME:

Securities transactions are recorded as of the trade date (the date the order to
buy or sell is executed). Realized gains and losses from securities sold are
recorded on the identified cost basis. Interest income is recorded on the
accrual basis. Dividend income is recorded on the ex-dividend date.

DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS:

Dividends from net investment income of the Balanced Portfolio are declared and
paid quarterly. Dividends from net investment income of the Capital Growth and
Growth Portfolios are declared and paid annually. Distributions of any net
long-term capital gains earned by a Portfolio are made annually. Distributions
of any net short-term capital gains earned by a Portfolio are distributed no
less frequently than annually at the discretion of the Board of Trustees. Income
distributions and capital gain distributions are determined in accordance with
income tax regulations which may differ from generally accepted accounting
principles. These differences are primarily due to differing treatments of
income and gains on various investment securities held by the Portfolios, timing
differences and differing characterization of distributions made by each
Portfolio as a whole.

FEDERAL INCOME TAXES:

It is each Portfolio's policy to qualify as a regulated investment company by
complying with the requirements of the Internal Revenue Code of 1986, as
amended, applicable to regulated investment companies and by, among other
things, distributing substantially all of its taxable and tax-exempt earnings to
its shareholders. Therefore, no Federal income tax provision is required.

EXPENSES:

Expenses that are directly related to one of the Portfolios are charged directly
to that Portfolio. General expenses of the Trust are allocated to the Portfolios
based upon the relative net assets of each Portfolio. In addition, the
Portfolios will indirectly bear their prorated share of expenses of the
Underlying Funds.

3.    INVESTMENT ADVISORY, SUB-ADVISORY, ADMINISTRATION FEES AND OTHER 
      TRANSACTIONS

As investment advisor to the Portfolios, Sierra Services provides its
proprietary asset allocation services to the Portfolios, formulates the
Portfolios' investment policies, analyzes economic and market trends, exercises
investment discretion over the assets of the Portfolios and monitors the
allocation of each Portfolio's assets and each Portfolio's performance. For its
investment advisory services to the Portfolios, Sierra Services is entitled to a
fee, which is calculated daily and paid monthly, at an annual rate of 0.10% of
each Portfolio's average daily net assets.

Sierra Services is a wholly-owned subsidiary of Sierra Capital Management
Corporation ("SCMC"), which is a wholly-owned subsidiary of Great Western
Financial Corporation ("GWFC"), a wholly-owned subsidiary of Washington Mutual,
Inc. ("Washington Mutual"), a publicly held corporation. Sierra Services is now
an indirect wholly-owned subsidiary of Washington Mutual.

Sierra Fund Administration Corporation ("Sierra Administration"), an indirect
wholly-owned subsidiary of Washington Mutual, serves as administrator to each
Portfolio. First Data Investor Services Group, Inc., a wholly-owned subsidiary
of First Data Corporation, serves as sub-administrator and transfer agent to
each Portfolio. For its services as administrator, each Portfolio pays Sierra
Administration a monthly fee at an annual rate of .15% of the value of each
Portfolio's average daily net assets. Out of its fee, Sierra Administration pays
First Data Investor Services Group, Inc. for its services as sub-administrator.
The Trust pays First Data Investor Services Group, Inc. certain out-of-pocket
expenses as transfer agent. Separately, the Trust pays First Data Investor
Services Group, Inc. for its services as transfer agent.

</TABLE>

6.    SHARES OF BENEFICIAL INTEREST

The Trust may issue an unlimited number of shares of beneficial interest, each
without par value.

7.    ORGANIZATION COSTS

Expenses incurred in connection with the organization of the Portfolios,
including the fees and expenses of registering and qualifying each Portfolio's
shares for distribution under Federal and state securities regulations, are
being amortized on a straight-line basis over a period of 60 months from
commencement of operations of each Portfolio. In the event any of the initial
shares of a Portfolio are redeemed by any holder thereof during the amortization
period, the proceeds of such redemptions will be reduced by an amount equal to
the pro-rata portion of the applicable Portfolio's unamortized deferred
organizational expenses in the same proportion as the number of shares being
redeemed bears to the number of initial shares of such Portfolio outstanding at
the time of such redemption.

8.    RISK FACTORS OF THE PORTFOLIOS

Investing in the Underlying Funds through the Portfolios involves certain
additional expenses and tax results that would not be present in a direct
investment in the Underlying Funds. Under certain circumstances, an Underlying
Fund may determine to make payment of a redemption request by a Portfolio wholly
or partly by a distribution in kind of securities from its portfolio, instead of
cash, in accordance with the rules of the Securities and Exchange Commission. In
such cases, the Portfolios may hold securities distributed by an Underlying Fund
until Sierra Services determines that it is appropriate to dispose of such
securities.

Certain Underlying Funds may: invest a portion of their assets in foreign
securities; enter into forward foreign currency transactions; lend their
portfolio securities; enter into stock index, interest rate and currency futures
contracts, and options on such contracts; enter into interest rate swaps or
purchase or sell interest rate caps or floors; engage in other types of options
transactions; make short sales; purchase zero coupon and payment-in-kind bonds;
engage in repurchase or reverse repurchase agreements; purchase and sell "when-
issued" securities and engage in "delayed-delivery" transactions; and engage in
various other investment practices each with inherent risks.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)

                           THE SIERRA VARIABLE TRUST

The Capital Growth Portfolio can invest as much as 50% of its total assets in
the Growth Fund and as much as 50% of its total assets in the Emerging Growth
Fund, each of which Underlying Funds may invest as much as 35% of its total
assets in lower-rated bonds. Securities rated below investment grade generally
involve greater price volatility and risk of principal and income and may be
less liquid than higher rated securities.

Certain Portfolios invest as much as 50% of their total assets in the Growth or
Emerging Growth Funds, each of which may invest up to 25% of its total assets in
foreign equity securities and as much as 5% of its total assets in securities in
developing or emerging markets countries. Certain Portfolios invest as much as
50% of their total assets in the International Growth Fund, which invests
primarily in the foreign equity securities, and may invest as much as 30% of its
total assets in securities in developing or emerging market countries. These
investments will subject such Portfolios to risks associated with investing in
foreign securities including those resulting from future adverse political and
economic developments and the possible imposition of currency exchange blockages
or other foreign governmental laws or restrictions.

The officers and Trustees of the Trust also serve as officers and Trustees of
the Underlying Funds. In addition, Sierra Services, the investment advisor and
distributor of each Portfolio, and Sierra Investment Advisors Corporation
("Sierra Advisors"), the investment advisor of the Underlying Funds, are both
wholly-owned subsidiaries of SCMC. Also, Sierra Services is the distributor of
the shares of the Underlying Funds. Conflicts may arise as these companies seek
to fulfill their fiduciary responsibilities to both the Portfolios and the
Underlying Funds.

From time to time, one or more of the Underlying Funds used for investment by a
Portfolio may experience relatively large investments or redemptions due to
reallocations or rebalancings by the Portfolios as recommended by Sierra
Services. These transactions will affect the Underlying Funds, since the
Underlying Funds that experience redemptions as a result of the reallocations or
rebalancings may have to sell portfolio securities and Underlying Funds that
receive additional cash will have to invest such cash. While it is impossible to
predict the overall impact of these transactions over time, there could be
adverse effects on portfolio management to the extent that the Underlying Funds
may be required to sell securities or invest cash at times when they would not
otherwise do so. These transactions could also have tax consequences if sales of
securities resulted in gains and could also increase transactions costs. Sierra
Advisors, representing the interests of the Underlying Funds, is committed to
minimizing the impact of Portfolio transactions on the Underlying Funds; Sierra
Services, representing the interest of the shareholders of the Portfolios, is
also committed to minimizing such impact on the Underlying Funds to the extent
it is consistent with pursuing the investment objectives of the Portfolios.
Sierra Advisors and Sierra Services will nevertheless face conflicts in
fulfilling their respective responsibilities because they are affiliates and
employ some of the same investment professionals.

Item 27.           Indemnification

                   Article VIII of the Registrant's Agreement and Declaration of
Trust provides in relevant part:

                   The Trust shall indemnify each of its Trustees and officers
                   (including persons who serve at the Trust's request as
                   directors, officers or trustees of another organization

<PAGE>   34

                   in which the Trust has any interest as a shareholder,
                   creditor or otherwise) (hereinafter referred to as a "Covered
                   Person") against all liabilities and expenses, including but
                   not limited to amounts paid in satisfaction of judgments, in
                   compromise or as fines and penalties, and counsel fees
                   reasonably incurred by any Covered Person in connection with
                   the defense or disposition of any action, suit or other
                   proceeding, whether civil or criminal, before any court or
                   administrative or legislative body, in which such Covered
                   Person may be or may have been involved as a party or
                   otherwise or with which such Covered Person may be or may
                   have been threatened, while in office or thereafter, by
                   reason of being or having been such a Covered Person except
                   with respect to any matter as to which such Covered Person
                   shall have been finally adjudicated in any such action, suit
                   or other proceeding to be liable to the Trust or its
                   Shareholders by reason of wilful misfeasance, bad faith,
                   gross negligence or reckless disregard of the duties involved
                   in the conduct of such Covered Person's office. Expenses,
                   including counsel fees so incurred by any such Covered Person
                   (but excluding amounts paid in satisfaction of judgments, in
                   compromise or as fines or penalties), shall be paid from time
                   to time by the Trust in advance of the final disposition of
                   any such action, suit or proceeding upon receipt of an
                   undertaking by or on behalf of such Covered Person to repay
                   amounts so paid to the Trust if it is ultimately determined
                   that indemnification of such expenses is not authorized under
                   this Article; provided, however, that either (a) such Covered
                   Person shall have provided appropriate security for such
                   undertaking, (b) the Trust shall be insured against losses
                   arising from any such advance payments or (c) either a
                   majority of the disinterested Trustees acting on the matter
                   (provided that a majority of the disinterested Trustees then
                   in office act on the matter), or independent legal counsel in
                   a written opinion, shall have determined, based upon a review
                   of readily available facts (as opposed to a full trial type
                   inquiry) that there is reason to believe that such Covered
                   Person will be found entitled to indemnification under this
                   Article.

                   As to any matter disposed of (whether by a compromise
                   payment, pursuant to a consent decree or otherwise) without
                   an adjudication by a court, or by any other body before which
                   the proceeding was brought, that such Covered Person is
                   liable to the Trust or its Shareholders by reason of wilful
                   misfeasance, bad faith, gross negligence or reckless
                   disregard of the duties involved in the conduct of his or her
                   office, indemnification shall be provided if (a) approved,
                   after notice that it involves such indemnification, by at
                   least a majority of the disinterested Trustees acting on the
                   matter (provided that a majority of the disinterested
                   Trustees then in office act on the matter) upon a
                   determination, based upon a review of readily available facts
                   (as opposed to a full trial type inquiry) that such Covered
                   Person is not liable to the Trust or its Shareholders by
                   reasons of wilful misfeasance, bad faith, gross negligence or
                   reckless disregard of the duties involved in the conduct of
                   his or her office, or (b) there has been obtained an opinion
                   in writing of independent legal counsel, based upon a review
                   of readily available facts (as opposed to a full trial type
                   inquiry) to the effect that such indemnification would not
                   protect such Person against any liability to the Trust to
                   which he or she would otherwise be subject by reason of
                   wilful misfeasance, bad faith, gross negligence or reckless
                   disregard of the duties involved in the conduct of his
                   office. Any approval pursuant to this Section shall not
                   prevent the recovery from any Covered Person of any

<PAGE>   35

                   amount paid to such Covered Person in accordance with this
                   Section as indemnification if such Covered Person is
                   subsequently adjudicated by a court of competent jurisdiction
                   to have been liable to the Trust or its Shareholders by
                   reason of wilful misfeasance, bad faith, gross negligence or
                   reckless disregard of the duties involved in the conduct of
                   such Covered Person's office.

                   Section 9 of the Sub-Adviser Agreements that are filed as
Exhibits 5(b)-2 and 5(b)- 7 to this Registration Statement are hereby
incorporated by reference in response to this item. They provide that, in the
absence of willful misfeasance, bad faith or gross negligence on the part of
J.P. Morgan, or reckless disregard of its obligations and duties thereunder
("Disqualifying Conduct"), J.P. Morgan shall not be subject to any liability to
the Trust or the Fund, or to any shareholder of the Fund, for any act or
omission in the course of, or connected with, rendering services hereunder. This
Section further provides that Sierra Advisors shall indemnify and hold harmless
J.P. Morgan from and against all claims, losses, liabilities or damages
(including reasonable attorneys' fees and other related expenses) (collectively,
"Losses"), howsoever arising under this Agreement or the performance by J.P.
Morgan of its duties thereunder; provided, however, that nothing contained
therein shall require that J.P. Morgan be indemnified for Losses resulting from
Disqualifying Conduct.

                   Section 11 of the Sub-Adviser Agreements that are filed as
Exhibits 5(b)-6 and 5(b)-9 to this Registration Statement are hereby
incorporated by reference in response to this item. They provide that Sierra
Advisors will indemnify and hold harmless Janus from and against any and all
claims, losses, liabilities or damages (including reasonable attorneys' fees and
other related expenses), howsoever arising from or in connection with these
Sub-Adviser Agreements or the performance by Janus of its duties thereunder;
provided, however, that nothing contained therein shall require that Janus be
indemnified for Disqualifying Conduct.

                   Section 12 of the Participation Agreement that is filed as
Exhibit 6(b) to this Registration Statement is hereby incorporated by reference
in response to this item. Section 12.1 thereof provides that American General
will indemnify the Trust and Sierra Services and their directors, trustees,
officers and controlling persons from losses and costs due to misstatements or
omissions of material facts for which American General is responsible in its
registration statement relating to annuities funded through the Trust or
otherwise or due to American General's failure to meet its obligations under the
Participation Agreement. Section 12.2 thereof provides that Sierra Services will
indemnify the Trust, American General, American General Securities and their
directors, trustees, officers and controlling persons from losses and costs due
to any misstatements or omissions of material facts for which Sierra Services or
its affiliates are responsible in American General registration statements
relating to annuities funded through the Trust or otherwise or as a result of
any failure by the Trust or Sierra Services to meet its obligations under the
Participation Agreement.

                   The Agreement filed as Exhibit 11(d) to this Registration
Statement is hereby incorporated by reference in response to this item. Pursuant
to that Agreement, Sierra Advisors and Sierra Services agree to indemnify
American General and American General Securities with respect to liabilities
arising out of the negligence or bad faith of Sierra Services, Sierra Advisors
or any sub- advisor to the Trust in performing their obligations to the Trust,
including the obligations of Sierra Advisors and the sub-advisors to operate the
Trust in compliance with Sub-Chapter M and Section 817(h) of the Internal
Revenue Code of 1986, as amended. Sierra Advisors and Sierra Services also

<PAGE>   36

agree to indemnify American General and American General Securities for 50% of
any other liabilities or costs that they may incur as a result of any failure of
the Trust to comply with Sub-Chapter M or Section 817(h) that does not result
from such negligence or bad faith.

                   Insofar as indemnification for liability arising under the
Securities Act of 1933, as amended (the "1933 Act"), may be permitted to
Trustees, officers and controlling persons of Registrant pursuant to the
foregoing provisions, or otherwise, Registrant has been advised that, in the
opinion of the Securities and Exchange Commission, such indemnification is
against public policy as expressed in the 1933 Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by Registrant of expenses incurred or paid
by a Trustee, officer or controlling person of Registrant in the successful
defense of any action, suit or proceeding) is asserted by such Trustee, officer
or controlling person in connection with the securities being registered,
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the 1933 Act and will be governed by the final adjudication of such
issue.
