(1) The Other Expenses for the Portfolios and the Funds are based on 1998
    operating experience, restated to reflect current expenses and voluntary fee
    waivers and credits allowed by the custodian. Other expenses are estimated
    for the current fiscal year for the Income Portfolio, Bond & Stock Fund, and
    Northwest Fund, because they do not have financial statements covering a
    period of at least 10 months. Absent fee waivers and credits allowed by the
    custodian, the Annual Expenses for the Strategic Growth Portfolio,
    Conservative Growth Portfolio, Balanced Portfolio, Flexible Income
    Portfolio, Income Portfolio, Money Market Fund, Short Term High Quality Bond
    Fund, U.S. Government Securities Fund, Income Fund, Bond & Stock Fund,
    Growth & Income Fund, Northwest Fund, Growth Fund, Emerging Growth Fund, and
    International Growth Fund for the 1998 fiscal year would have been 0.80%,

    the underlying Funds are shown under "Annual Expenses of the Portfolios and
    Underlying Funds Combined," immediately following.

ANNUAL EXPENSES OF THE PORTFOLIOS AND UNDERLYING FUNDS COMBINED

Each Portfolio will invest in Funds of the Trust and in the WM High Yield Fund
(a series of WM Trust I). You will indirectly bear certain expenses associated
with those Funds. The chart below shows estimated combined annual expenses for
each Portfolio and the Funds in which that Portfolio may invest. The expenses
are based upon estimated expenses of each Portfolio and underlying Fund for the
fiscal year ended December 31, 1998, restated to reflect current expenses and
voluntary waivers and credits allowed by the custodian. Please refer to the
Trust prospectus for more details.

The estimates assume a constant allocation of each Portfolio's  assets among the
Funds identical to such Portfolio's actual allocation at December 31, 1998.

                        SYNOPSIS OF CONTRACT PROVISIONS

You should read this synopsis together with the other information in this
Prospectus.

The purpose of the Contracts is to provide retirement benefits through:

  .  the accumulation of purchase payments on a fixed or variable basis, and

  .  the application of such accumulations to provide Fixed or Variable Annuity
     Payments.

MINIMUM INVESTMENT REQUIREMENTS

Your initial purchase payment must be at least $2,000, if you are buying a
Qualified Contract, and $5,000, if you are buying a Non-Qualified Contract. (See
"Federal Income Tax Matters" for a discussion of the various tax aspects
involved in purchasing Qualified and Non-Qualified Contracts.) The amount of any
subsequent purchase payment that you make must be at least $100. If your Account
Value falls below $500, we may cancel your Contract and treat it as a full
surrender. We also may transfer funds, without charge, from a Division (other
than the Money Market Fund Division) or Guarantee Period under your Contract to
the Money Market Fund Division, if the Account Value of that Division or
Guarantee Period falls below $500. (See "Contract Issuance and Purchase
Payments.")

PURCHASE PAYMENT ACCUMULATION

We accumulate purchase payments on a variable or fixed basis until the Annuity
Commencement Date.

For variable accumulation, you may allocate part or all of your Account Value to
one or more of the 15 available Divisions of the Separate Account. Each Division
invests solely in shares of one of 15 corresponding Series. (See "The Series.")
The value of accumulated purchase payments allocated to a Division increases or
decreases, as the value of the investments in a Series' shares increases or
decreases, subject to reduction by charges and deductions. (See "Variable
Account Value.")

For fixed accumulation, you may allocate part or all of your Account Value to
one or more of the Guarantee Periods available in our Fixed Account at the time
you make your allocation. Each Guarantee Period is for a different period of
time and has a different Guaranteed Interest Rate. The value of accumulated
purchase payments increases at the Guaranteed Interest Rate applicable to that
Guarantee Period. (See "The Fixed Account.")

Over the lifetime of your Contract, you may allocate part or all of your Account
Value to no more than 18 Divisions and Guarantee Periods. This limit includes
those Divisions and Guarantee Periods from which you have either transferred or
withdrawn all of your Account Value previously allocated to such Divisions or
Guarantee Periods. For example, if you allocate 100% of your initial purchase
payment to the Money Market Fund Division, you have selected the Money Market
Fund Division as one of the 18 Divisions and Guarantee Periods available to you.
When you transfer all of your Account Value from the Money Market Fund Division,
it remains in one of the 18 Divisions and Guarantee Periods available to you,
even if you never again allocate any of your Account Value or a new purchase
payment to the Money Market Fund Division.

FIXED AND VARIABLE ANNUITY PAYMENTS

You may elect to receive Fixed or Variable Annuity Payments or a combination of
Payments beginning on the Annuity Commencement Date. Fixed Annuity Payments are
periodic payments from AGL in a fixed amount guaranteed by AGL. The amount of
the Payments will depend on the Annuity Payment Option chosen, the age and, in
some cases, the gender of the Annuitant, and the total amount of Account Value
applied to the fixed Annuity Payment Option.

Variable Annuity Payments are similar to Fixed Annuity Payments, except that the
amount of each periodic payment from AGL will vary reflecting the net investment
return of the Division or Divisions you

     

                                       8
<PAGE>
 
    


selected under your variable Annuity Payment Option. The payment for a given
month will exceed the previous month's payment, if the net investment return for
a given month exceeds the assumed interest rate used in the Contract's annuity
tables. The monthly payment will be less than the previous payment, if the net
investment return for a month is less than the assumed interest rate. The
assumed interest rate used in the Contract's annuity tables is 3.5%. AGL may
offer other forms of the Contract with a lower assumed interest rate and
reserves the right to discontinue the offering of the higher interest rate form
of Contract. (See "Annuity Period and Annuity Payment Options.")

CHANGES IN ALLOCATIONS AMONG DIVISIONS AND GUARANTEE PERIODS

Before the Annuity Commencement Date, you may change your allocation of future
purchase payments to the various Divisions and Guarantee Periods, without
charge.

In addition, you may reallocate your Account Value among the Divisions and
Guarantee Periods before the Annuity Commencement Date. However, you are
limited in the amount that you may transfer out of a Guarantee Period. See
"Transfer, Automatic Rebalancing, Surrender and Partial Withdrawal of Owner
Account Value -- Transfers," for these and other conditions of transfer.

After the Annuity Commencement Date, you may make transfers from a Division to
another Division or to a fixed Annuity Payment Option. However, you may not make
transfers from a fixed Annuity Payment Option. (See "Annuity Period and Annuity
Payment Options -- Transfers.")

SURRENDERS AND WITHDRAWALS

You may make a total surrender of or partial withdrawal from your Contract at
any time before the Annuity Commencement Date by Written request to us. A
surrender or partial withdrawal may require you to pay a Surrender Charge, and
some surrenders and partial withdrawals may require you to pay tax penalties.
(See "Surrenders and Partial Withdrawals.")

CANCELLATION RIGHT

You may cancel your Contract by delivering it or mailing it with a Written
cancellation request to our Home Office or to your sales representative, before
the close of business on the 10th day after you receive the Contract. In some
states the Contract provides for a 20-or 30-day period. If you send the items by
mail, properly addressed and postage prepaid, we will consider them received at
our Home Office on the date we actually receive them.

We will refund to you, in most states, the sum of:

  .  your Account Value, and

  .  any premium taxes and Annual Contract Fee that have been deducted.

Some states require us to refund the sum of your purchase payments if it is
larger than the amount just described. Other states allow us to refund only the
sum of your purchase payments.

DEATH PROCEEDS

If the Annuitant or Owner dies before the Annuity Commencement Date, we will pay
a benefit to the Beneficiary. (See "Death Proceeds Before the Annuity
Commencement Date.")

LIMITATIONS IMPOSED BY RETIREMENT PLANS AND EMPLOYERS

An employer or trustee who is the Owner under a retirement plan may limit
certain rights you would otherwise have under a Contract. These limitations may
restrict total and partial withdrawals, the amount or timing of purchase
payments, the start of annuity payments, and the type of annuity options that
you may select. You should familiarize yourself with the provisions of any
retirement plan in which a Contract is used. We are not responsible for
monitoring or assuring compliance with the provisions of any retirement plan.

COMMUNICATIONS TO US

You should include, in communications to us, your Contract number, your name,
and, if different, the Annuitant's name. You may direct communications to the
addresses and phone numbers on the first page of this Prospectus.

Unless the Prospectus states differently, we will consider purchase payments or
other communications to be received at our Home Office on the date we actually
receive them, if they are in proper form. However, we will consider purchase
payments to be received on the next Valuation Date if we receive them (1) after
the close of regular trading on The New York Stock Exchange or (2) on a date
that is not a Valuation Date.

FINANCIAL AND PERFORMANCE INFORMATION

We include financial statements of AGL and the WM Strategic Asset Manager
Divisions of Separate Account D in the Statement of Additional Information (see
"Contents of Statement of Additional Information.") The Separate Account
financial statements include information only about the Divisions that invest in
the Portfolios and Funds of the Trust.

From time to time, the Separate Account may include in advertisements and other
sales materials several types of performance information for the Divisions. This
information may include "average annual total return," "total return," and
"cumulative total return." The Money Market Fund Division may also advertise
"effective yield."

The performance information that we may present is not an estimate or guarantee
of future investment performance and does not represent the actual investment
experience of amounts invested by a particular Owner. Additional information
concerning a Division's performance appears in the Statement.

Total Return and Yield Quotations.  Average annual total return, total return,
and cumulative total return figures measure the net income of a Division and any
realized or unrealized gains or losses of the underlying investments in the
Division, over the period stated. Average annual total return figures are
annualized and represent the average annual percentage change in the value of an
investment in a Division over the period stated. Total return figures are also
annualized, but do not, as described below, reflect deduction of any applicable
Surrender Charge or Annual Contract Fee. Cumulative total return figures
represent the cumulative change in value of an investment in a Division for
various periods stated.

Yield is a measure of the net dividend and interest income earned over a
specific one-month or 30-day period (seven-day period for the Money Market Fund
Division), expressed as a percentage of the value of the Division's Accumulation
Units. Yield is an annualized figure, which means that we assume that the
Division generates the same level of net income over a one-year period and
compound that income on a semi-annual basis. We calculate the effective yield
for the Money Market Fund Division similarly, but include the increase due to
assumed compounding. The Money Market Fund Division's effective yield will be
slightly higher than its yield due to this compounding effect.

Average annual total return figures reflect deduction of all recurring charges
and fees applicable under the Contract to all Owner accounts, including the
following:

  .  the Mortality and Expense Risk Charge,

  .  the Administrative Expense Charge,

  .  the applicable Surrender Charge that may be charged at the end of the
     period in question, and

  .  a prorated portion of the Annual Contract Fee.

Yield, effective yield, total return, and cumulative total return figures do not
reflect deduction of any Surrender Charge that we may impose upon partial
withdrawal, and may be higher than if the charge were deducted. Total return and
cumulative total return figures also do not reflect deduction of the Annual
Contract Fee.

Division Performance.  The investment performance for each Division that invests
in a corresponding Series of the Trust will reflect the investment performance
of that Series for the periods stated. This information appears in the
Statement. For periods before the date the Contracts became available, we
calculate the performance information for a Division on a hypothetical basis. In
so doing, we reflect deductions of current Separate Account fees and charges
under the Contract from the historical performance of the corresponding Series.
We may waive or reimburse certain fees or charges applicable to the Contract.
Such waivers or reimbursements will affect each Division's performance results.

Information about the experience of the investment advisers to the Series of the
Trust appears in the prospectus for the Trust.

AGL may also advertise or report to Owners its ratings as an insurance company
by the A. M. Best Company. Each year, A. M. Best reviews the financial status of
thousands of insurers, culminating in the assignment of Best's Ratings. These
ratings reflect A. M. Best's current opinion of the relative financial strength
and operating performance of an insurance company in comparison to the norms of
the life/health industry. Best's Ratings range from A++ to F.

AGL may also advertise or report to Owners its ratings as to claims-paying
ability by the Standard & Poor's Corporation. A Standard & Poor's insurance
claims-paying ability rating is an assessment of an operating insurance
company's financial capacity to meet the obligations of its insurance policies
in accordance with their terms. Standard & Poor's ratings range from AAA to D.

AGL may additionally advertise its ratings as to claims-paying ability by the
Duff & Phelps Credit Rating Co. A Duff & Phelps' claims-paying ability rating is
an assessment of a company's insurance claims-paying ability. Duff & Phelps'
ratings range from AAA to CCC.

Current ratings from A. M. Best, Standard & Poor's, and Duff & Phelps may be
used from time to time in any advertising about the Contracts, as well as in any
reports that publish the ratings.

The ratings reflect the claims-paying ability and financial strength of AGL.
They are not a rating of investment performance that purchasers of insurance
products funded through separate accounts, such as the Separate Account, have
experienced or are likely to experience in the future.

OTHER INFORMATION

AGL may also advertise endorsements from organizations, individuals or other
parties that recommend AGL or the Contracts. AGL may occasionally include in
advertisements (1) comparisons of currently taxable and tax-deferred investment
programs, based on selected tax brackets, or (2) discussions of alternative
investment vehicles and general economic conditions.

The following table shows the Accumulation Unit value for the Divisions

                             FINANCIAL INFORMATION

The financial statements of AGL appear in the Statement. Please see the first
page of this Prospectus for information on how to obtain a copy of the
Statement. You should consider the financial statements of AGL only as bearing
on the ability of AGL to meet its contractual obligations under the Contracts.
The financial statements do not bear on the investment performance of the
Separate Account. (See "Contents of Statement of Additional Information.")

The financial statements of the WM Strategic Asset Manager Divisions of Separate
Account D also appear in the Statement. They provide financial information about
the WM Strategic Asset Manager Divisions which invest in the Series of the
Trust. (See "Contents of Statement of Additional Information.")

                                      AGL

AGL is a stock life insurance company organized under the laws of the State of
Texas, which is a successor in interest to a company originally organized under
the laws of the State of Delaware in 1917. AGL is an indirect, wholly-owned
subsidiary of American General Corporation, a diversified financial services
holding company engaged primarily in the insurance business. The commitments
under the Contracts are AGL's, and American General Corporation has no legal
obligation to back those commitments.

                              SEPARATE ACCOUNT D

AGL established Separate Account D on November 19, 1973. The Separate Account
has 69 Divisions, 15 of which are available under the Contracts offered by this
Prospectus. The Separate Account is registered with the Securities and Exchange
Commission as a unit investment trust under the 1940 Act.

Each Division of the Separate Account is part of AGL's general business. The
assets of the Separate Account belong to AGL. Under Texas law and the terms of
the Contracts, the assets of the Separate Account will not be chargeable with
liabilities arising out of any other business that AGL may conduct. These assets
will be held exclusively to meet AGL's obligations under variable annuity
Contracts. Furthermore, AGL credits or charges the Separate Account with the
income, gains, and losses from the Separate Account's assets, whether or not
realized, without regard to other income, gains, or losses of AGL.

     

                                       12

                                  THE SERIES

The Separate Account has 15 Divisions funding the variable benefits under the
Contracts. These Divisions invest in shares of 15 Series (the five Portfolios
and the 10 Funds) of the Trust.

The Trust offers shares of these Series, without sales charges, exclusively to
Separate Account D. The Trust may, in the future, also offer shares to variable
annuity and variable life insurance separate accounts of insurers that are not
affiliated with AGL.

We do not foresee any disadvantage to you arising out of these arrangements.
Nevertheless, differences in treatment under tax and other laws, as well as
other considerations, could cause the interests of various owners to conflict.

For example, violation of the federal tax laws by one separate account investing
in the Trust could cause the Contracts or contracts funded through another
separate account to lose their tax deferred status. Such a result might require
us to take remedial action. A separate account may have to withdraw its
participation in the Trust, if a material irreconcilable conflict arises between
separate accounts. In such event, the Trust may have to liquidate portfolio
securities at a loss to pay for a separate account's redemption of Trust shares.
At the same time, the Trust's Board of Trustees and we will monitor events for
any material irreconcilable conflicts that may possibly arise and determine what
action, if any, to take to remedy or eliminate the conflict.

We automatically reinvest any dividends or capital gain distributions that we
receive on shares of the Series held under Contracts. We reinvest at the Series'
net asset value on the date payable. Dividends and distributions will reduce the
net asset value of each share of the corresponding Series and increase the
number of shares outstanding of the Series by an equivalent value. However,
these dividends and distributions do not change your Account Value.

The names of the Series of the Trust in which the available Divisions invest are
as follows:

  .  Strategic Growth Portfolio

  .  Conservative Growth Portfolio

  .  Balanced Portfolio

  .  Flexible Income Portfolio

  .  Income Funds Portfolio

  .  Money Market Fund

  .  Short Term High Quality Bond Fund

  .  U.S. Government Securities Fund

  .  Income Fund

  .  Bond & Stock Fund

  .  Growth & Income Fund

  .  Northwest Fund

  .  Growth Fund

  .  Emerging Growth Fund

  .  International Growth Fund

WM Advisors, Inc. is the investment adviser of each Series of the Trust. WM Fund
Services, Inc. is the distributor of shares of each Series of the Trust. Neither
company is affiliated with AGL.

Before selecting any Division, you should carefully read the Trust prospectus,
which is attached at the end of this Prospectus. The Trust prospectus discusses
detailed information about the Series in which each Division invests, including
investment objectives and policies, charges and expenses. The Trust prospectus
also provides detailed information about the Trust's allocation of the assets of
each Portfolio among the other Series of the Trust and the WM High Yield Fund
(the "Underlying Funds"), and about the predetermined investment limits and the
diversification requirements of the Code that govern this allocation
("allocation limitations"). Each Portfolio will invest in different combinations
of the Underlying Funds. AGL understands that the effect of the Portfolios'
allocation limitations is that each Portfolio will allocate its assets to at
least five of the Underlying Funds. AGL also understands that the effect of the
Portfolios' voting procedures is that owners will have the privilege of voting
Portfolio shares and not Underlying Fund shares. (See "Voting Privileges.")
Please refer to the Trust prospectus for more details.

Lower-rated fixed income securities, such as those in which the Income, Bond &
Stock, Growth & Income, Growth and Emerging Growth Funds may invest up to 35% of
their total assets, are subject to greater risk of loss of income and principal
and generally subject to greater market fluctuations than investments in lower
yielding fixed income securities. You should carefully read about these Funds in
the Trust's prospectus and related statement of additional information and
consider your ability to assume the risks of making an investment in the
Divisions which invest in them.

You may obtain additional copies of a Prospectus by contacting AGL's Annuity
Administration Department at the addresses and phone number on the first page of
this Prospectus. When making your request, please specify the Series in which
you are interested.

VOTING PRIVILEGES

The following people may give us voting instructions for Series shares held in
the Separate Account Divisions attributable to their Contract:

  .  You, as the Owner, before the Annuity Commencement Date, and

  .  The Annuitant or other payee, during the Annuity Period.

We will vote according to such instructions at meetings of shareholders of the
Series.

We will determine who is entitled to give voting instructions and the number of
votes for which they may give directions as of the record date for a meeting. We
will calculate the number of votes in fractions. We will calculate the number of
votes for any Series as follows:

  .  For each Owner before the Annuity Commencement Date, we will divide (1) the
     Owner's Variable Account Value invested in the corresponding Division by
     (2) the net asset value of one share of that Series.

  .  For each Annuitant or payee during the Annuity Period, we will divide (1)
     our liability for future Variable Annuity Payments to the Annuitant or
     payee by (2) the value of an Annuity Unit. We will calculate our liability
     for future Variable Annuity Payments based on the mortality assumptions and
     the assumed interest rate that we use in determining the number of Annuity
     Units under a Contract and the value of an Annuity Unit.

We will vote all shares of each Series owned by the Separate Account as follows:

  .  Shares for which we receive instructions, in accordance with those
     instructions, and

  .  Shares for which we receive no instructions, in the same proportion as the
     shares for which we receive instructions.

Shares of each Series may be owned by separate accounts of insurance companies
other than us. We understand that each Series will see that all insurance
companies vote shares uniformly.

We believe that our voting instruction procedures comply with current federal
securities law requirements. However, we reserve the right to modify these
procedures to conform with legal requirements and interpretations that are put
in effect or modified from time to time.

                               THE FIXED ACCOUNT

Amounts in the Fixed Account or supporting Fixed Annuity Payments become part of
our General Account. We have not registered interests in the General Account
under the Securities Act of 1933, and we have not registered the General Account
as an investment company under the 1940 Act, based on federal law exclusion and
exemption. The staff of the Securities and Exchange Commission has advised us
that it has not reviewed the disclosures in this Prospectus that relate to the
Fixed Account or Fixed Annuity Payments. At the same time, we have legal
responsibility for the accuracy and completeness of this Prospectus.

The Fixed Account is not available under Contracts purchased in Oregon.

Our obligations for the Fixed Account are legal obligations of AGL. Our General
Account assets support these obligations. These General Account assets also
support our obligations under other insurance and annuity contracts. Investments
purchased with amounts allocated to the Fixed Account are the property of AGL.
Owners have no legal rights in such investments.

GUARANTEE PERIODS

Account Value that the Owner allocates to the Fixed Account earns a Guaranteed
Interest Rate beginning with the date of the allocation. This Guaranteed
Interest Rate continues for the number of months or years that the Owner selects
from among the Guarantee Periods that we then offer.

At the end of a Guarantee Period, we will allocate your Account Value in that
Guaran-

     

                                       14
<PAGE>
 
    


tee Period, including interest you have earned, to a new Guarantee Period
of the same length. In the alternative, the Owner may submit a Written request
to us to allocate this amount to a different Guarantee Period or Periods or to
one or more of the Divisions of the Separate Account. We must receive this
Written request at least three business days before the end of the Guarantee
Period.

We will contact the Owner regarding the scheduled Annuity Commencement Date, if
the Owner has not provided the necessary Written request and the renewed
Guarantee Period extends beyond the scheduled Annuity Commencement Date. If the
Owner elects to annuitize in this case, we will, under certain circumstances,
waive the Surrender Charge. (See "Annuity Payment Options" and "Surrender
Charge.")

If the Owner does not annuitize on the scheduled Annuity Commencement Date, we
will move the Annuity Commencement Date to the earlier of the end of the renewed
Guarantee Period or the latest possible Annuity Commencement Date. (See "Annuity
Commencement Date.")

The first day of the new Guarantee Period (or other reallocation) will be the
day after the end of the prior Guarantee Period. We will notify the Owner in
writing at least 30 days and not more than 60 days before the end of any
Guarantee Period.

If the Owner's Account Value in a Guarantee Period is less than $500, we reserve
the right to transfer, without charge, the balance to the Money Market Fund
Division at the end of that Guarantee Period. However, we will transfer such
balance to another Division selected by the Owner, if we have received Written
instructions to transfer such balance to that Division.

CREDITING INTEREST

We declare the Guaranteed Interest Rate from time to time as market conditions
dictate. We tell an Owner the Guaranteed Interest Rate for a Guarantee Period at
the time we receive a purchase payment, make a transfer, or renew a Guarantee
Period. We may credit a different interest rate to one Guarantee Period than to
another Guarantee Period that began on a different date. The minimum Guaranteed
Interest Rate is an effective annual rate of 3%.

AGL's management makes the final determination of the Guaranteed Interest Rates
to be declared. AGL cannot predict or assure the level of any future Guaranteed
Interest Rates in excess of the minimum Guaranteed Interest Rate stated in your
Contract.

You may obtain information concerning the Guaranteed Interest Rates applicable
to the various Guarantee Periods at any time from your sales representative or
from the addresses or telephone numbers on the first page of this Prospectus.

NEW GUARANTEE PERIODS

Each allocation or transfer of an amount to a Guarantee Period starts the
running of a new Guarantee Period for that amount. That new Guarantee Period
will earn a Guaranteed Interest Rate that will continue unchanged until the end
of that Period. The Guaranteed Interest Rate will never be less than the minimum
Guaranteed Interest Rate stated in your Contract.

Each Guarantee Period has its own Guaranteed Interest Rate. Guarantee Periods
can have different Guaranteed Interest Rates. We have the right to change the
Guaranteed Interest Rate for future Guarantee Periods of various lengths. These
changes will not affect the Guaranteed Interest Rates being paid on Guarantee
Periods that have already started. Each allocation or transfer of an amount to a
Guarantee Period starts the running of a new Guarantee Period for the amount
allocated or transferred. That amount earns a Guaranteed Interest Rate that will
continue unchanged until the end of that Period. The Guaranteed Interest Rate
will never be less than the minimum Guaranteed Interest Rate stated in your
Contract. We may offer one or more Guarantee Periods with a required dollar cost
averaging feature. (See "Transfers.") Currently we make available a one-year
Guarantee Period, and no others. However, we reserve the right to change the

                    CONTRACT ISSUANCE AND PURCHASE PAYMENTS

The minimum initial purchase payment is $2,000 for a Qualified Contract and
$5,000 for a Non-Qualified Contract. The minimum subsequent purchase payment is
$100. We reserve the right to modify these minimums at our discretion.

Your application to purchase a Contract must be on a Written application that we
provide and that you sign. AGL and WM Fund Services, Inc., as distributor of the
Contracts, may agree on a different medium or format for the application. When a
purchase payment accompanies an application to purchase a Contract and you have
properly completed the application, we will either:

  .  process the application, credit the purchase payment, and issue the
     Contract, or

  .  reject the application and return the purchase payment within two Valuation
     Dates after receipt of the application at our Home Office.

If you have not completed the application or have not completed it correctly, we
will request additional documents or information within five Valuation Dates
after receipt of the application at our Home Office.

If we have not received a correctly completed application within five Valuation
Dates after receipt of the purchase payment at our Home Office, we will return
the purchase payment immediately. However, you may specifically consent to our
retaining the purchase payment until you complete the application. In that case,
we will credit the initial purchase payment as of the end of the Valuation
Period in which we receive, at our Home Office, the last information required to
process the application.

We will credit subsequent purchase payments as of the end of the Valuation
Period in which we receive them and any required Written information at our Home
Office.

We reserve the right to reject any application or purchase payment for any
reason.

MINIMUM REQUIREMENTS

If your Account Value in any Division falls below $500 because of a partial
withdrawal from the Contract, we reserve the right to transfer, without charge,
the remaining balance to the Money Market Fund Division.

If your Account Value in any Division falls below $500 because of a transfer to
another Division or to the Fixed Account, we reserve the right to transfer the
remaining balance in that Division, without charge and pro rata, to the
investment option or options to which the transfer was made. We will waive these
minimum requirements for transfers under the automatic rebalancing program. (See
"Automatic Rebalancing.")

If your total Account Value falls below $500, we may cancel the Contract. We
consider such a cancellation a full surrender of the Contract. We will provide
you with 60 days advance notice of any such cancellation.

So long as the Account Value does not fall below $500, you do not have to make
further purchase payments. You may, however, elect to make subsequent purchase
payments at any time before the Annuity Commencement Date, if the Owner and
Annuitant are still living.

PAYMENTS

You should make checks for subsequent purchase payments payable to American
General Life Insurance Company and forward them directly to our Home Office. We
also accept purchase payments by wire, by direct transfer from your checking,
savings or brokerage account, or by exchange from another insurance company. You
may obtain further information about how to make purchase payments by any of
these methods from your sales representative or from us at the addresses and
telephone numbers on the first page of this Prospectus.

You may make purchase payments pursuant to employer sponsored plans only with
our agreement.

Your purchase payments are allocated to the Divisions of the Separate Account or
the Guarantee Period of the Fixed Account as of the date we credit the purchase
payments to your Contract. In your application form, you select (in whole
percentages) the amount of each purchase payment that you are allocating to each
Division and Guarantee Period. You can change these allocation percentages at
any time by Written notice to us.

                              OWNER ACCOUNT VALUE

Before the Annuity Commencement Date, your Account Value under a Contract is the
sum of your Variable Account Value and Fixed Account Value, as discussed below.

VARIABLE ACCOUNT VALUE

As of any Valuation Date before the Annuity Commencement Date:

  .  Your Variable Account Value is the sum of your Variable Account Values in
     each Division of the Separate Account.

  .  Your Variable Account Value in a Division is the product of the number of
     your Accumulation Units in that Division multiplied by the value of one
     such Accumulation Unit as of that Valuation Date.

There is no guaranteed minimum Variable Account Value. To the extent that your
Account Value is allocated to the Separate Account, you bear the entire
investment risk.

We credit Accumulation Units in a Division to you when you allocate purchase
payments or transfer amounts to that Division. Similarly, we redeem Accumulation
Units when you transfer or withdraw amounts from a Division or when we pay
certain charges under the Contract. We determine the value of these Accumulation
Units at the end of the Valuation Date on which we make the credit or charge.

The value of an Accumulation Unit for a Division on any Valuation Date is equal
to the previous value of that Division's Accumulation Unit multiplied by that
Division's net investment factor for the Valuation Period ending on that
Valuation Date.

The net investment factor for a Division is determined by dividing (1) the net
asset value per share of the Series shares held by the Division, determined at
the end of the current Valuation Period, plus the per share amount of any
dividend or capital gains distribution made for the Series shares held by the
Division during the current Valuation Period, by (2) the net asset value per
share of the Series shares held in the Division determined at the end of the
previous Valuation Period. We then subtract from that result a factor
representing the mortality risk, expense risk and administrative expense charge.

FIXED ACCOUNT VALUE

As of any Valuation Date before the Annuity Commencement Date:

  .  Your Fixed Account Value is the sum of your Fixed Account Value in all
     Guarantee Periods.

  .  Your Fixed Account Value in a Guarantee Period is equal to the following
     amounts, in each case increased by accrued interest at the applicable
     Guaranteed Interest Rate: (1) the amount of net purchase payments, renewals
     and transferred amounts allocated to the Guarantee Period, less (2) the
     amount of any transfers or withdrawals out of the Guarantee Period,
     including withdrawals to pay applicable charges.

AGL guarantees the Fixed Account Value. AGL bears the investment risk for
amounts allocated to the Fixed Account, except to the extent that AGL may vary
the Guaranteed Interest Rate for future Guarantee Periods (subject to the 3%
minimum Guaranteed Interest Rate stated in your Contract).

            TRANSFER, AUTOMATIC REBALANCING, SURRENDER AND PARTIAL
                       WITHDRAWAL OF OWNER ACCOUNT VALUE

TRANSFERS

You can transfer your Account Value beginning 30 days after we issue your
Contract and before the Annuity Commencement Date. The following rules apply:

  .  You may transfer your Account Value at any time among the available
     Divisions of the Separate Account and the Guarantee Period. Transfers will
     be effective at the end of the Valuation Period in which we receive your
     Written or telephone transfer request.

  .  If a transfer causes your Account Value in any Division or the Guarantee
     Period to fall below $500, we reserve the right to transfer the remaining
     balance in that Division or the Guarantee Period in the same proportions as
     the transfer request.

  .  You may make up to 12 transfers each Contract Year without charge. We will
     charge you $25 for each additional transfer.

  .  You may transfer no more than 25% of the Account Value you allocated to the
     Guarantee Period at its inception during any Contract Year. This 25%
     limitation does not apply to transfers from the Guarantee period (1) within
     15 days before or after the end of the Guarantee Period in which you held
     the transferred amounts, or (2) a renewal at the end of the Guarantee
     Period to the same Guarantee Period.

You may establish an automatic transfer plan. (We also refer to this plan as a
dollar cost averaging plan.) The rules about transfers, which we describe above,
will apply to this plan. Under this plan, we will automatically transfer amounts
from any Division or the one-year Guarantee Period (or any other Guarantee
Period that is available at that time) to one or more other Divisions. You will
select:

  .  the amount we are to transfer under the plan;

  .  the frequency of the transfers -- either monthly, quarterly, semi-annually,
     or annually; and

  .  the duration of the plan.

We may also offer certain "special automatic transfer plans" to Owners who:

  .  make new purchase payments, and

  .  do not own another annuity contract which AGL, or any AGL affiliate,
     issued.

Under such plans, we will make equal monthly transfers over a period of time
that we will determine. We may offer a higher Guaranteed Interest Rate under
such a special automatic transfer plan than we would offer for another Guarantee
Period of the same duration that is not offered under such a plan. Any such
higher interest rate will reflect differences in costs or services and will not
be unfairly discriminatory as to any person.

Differences in costs or services will result from such factors as reduced sales
expenses or administrative efficiencies related to transferring amounts to other
Divisions on an automatic, rather than a discretionary, basis.

Transfers under any automatic transfer plan will:

  .  not count towards the 12 free transfers each Contract Year,

  .  not incur a $25 charge,

  .  not be subject to the 25% limitation on transfers from the Guarantee
     Period, and

  .  not be subject to the minimum Account Value requirement described above.

You may obtain additional information about how to establish an automatic
transfer plan from your sales representative or from us at the telephone numbers
and addresses on the first page of this Prospectus. You cannot have an automatic
transfer plan in effect at the same time you have Automatic Rebalancing,
described below, in effect.

You can make transfers by telephone if you have completed a Telephone Transfer
Authorization form and given it to us. The form provides certain rules about
telephone transfers which you will have to follow. We will honor telephone
transfer instructions from any person who provides the correct information. So
there is a risk of possible loss to you if an

     

                                       18
<PAGE>
 
    


unauthorized person uses this service in your name. Currently we try to limit
the availability of telephone transfers only to the Owner of the Contract. We
are not liable for any acts or omissions based upon telephone instructions that
we reasonably believe to be genuine. We are not responsible for losses arising
from errors in the communication of transfer instructions.

We have established procedures for accepting telephone transfer instructions,
which include:

  .  verification of the Contract number;

  .  verification of the identity of the caller;

  .  verification of both the Annuitant's and Owner's names; and

  .  a form of personal identification from the caller.

We will mail to the Owner a written confirmation of the transaction. We might
receive telephone transfer instructions from more than one person on the same
day, or our recording equipment might malfunction. It may be impossible for you
to make a telephone transfer at the time you wish. If this occurs, you should
submit a Written transfer request. Also, we will not process the transaction if,
due to malfunction or other circumstances, the recording of your telephone
request is incomplete or not fully comprehensible. The phone number for
telephone exchanges is 1-800-277-0914.

We have not designed the Contracts for professional market timing organizations
or other entities using programmed and frequent transfers. We may not
unilaterally terminate or discontinue transfer privileges. However, we reserve
the right to suspend such privileges for a reasonable period.

AUTOMATIC REBALANCING

You may arrange for Automatic Rebalancing among the Separate Account Divisions,
if your Contract has an Account Value of $25,000 or more at the time we receive
the application for Automatic Rebalancing. You may apply for Automatic
Rebalancing either at issue or after issue, and you may subsequently discontinue
it. The five Portfolios are not available for rebalancing.

Under Automatic Rebalancing, we transfer funds among the Separate Account
Divisions to maintain the percentage allocation you have selected for each
Division. At your election, we will make these transfers on a quarterly, semi-
annual or annual basis, measured from the Contract Anniversary date. A Contract
Anniversary date that falls on the 29th, 30th, or 31st of the month will result
in Automatic Rebalancing starting with the 1st of the next month.

Automatic Rebalancing does not permit transfers to or from any Guarantee Period.
Transfers under Automatic Rebalancing will not count towards the 12 free
transfers each Contract Year and will not incur a $25 charge. You cannot have
Automatic Rebalancing in effect at the same time you have an automatic transfer
plan, described above, in effect.

SURRENDERS

At any time before the Annuity Commencement Date and while the Annuitant is
still living, the Owner may make a full surrender from a Contract.

We will pay you the following upon full surrender:

  .  your Account Value at the end of the Valuation Period in which we receive a
     Written surrender request,

  .  minus any applicable Surrender Charge,

  .  minus any uncollected Contract Fee (see "Annual Contract Fee"), and

  .  minus any applicable premium tax.

Our current practice is to require that you return the Contract to our Home
Office with any request for a full surrender.

After a full surrender, or if the Owner's Account Value falls to zero, all
rights of the Owner, Annuitant or any other person under the Contract will
terminate. The Owner will, however have a right to reinvest the proceeds of the
Contract. (See "One-Time Reinstatement Privilege.")

All collateral assignees of record must consent to any full surrender.

PARTIAL WITHDRAWALS

Your Written request for a partial withdrawal should specify the Divisions of
the Separate Account, or the Guarantee Periods of the Fixed Account, from which
you wish to make the partial withdrawal. We will take the withdrawal pro rata
from the Divisions and the Guarantee Period, if (1) you do not tell us how to
make the withdrawal, or (2) we cannot make the withdrawal as you requested.

     

                                       19
<PAGE>
 
    


Partial withdrawal requests must be for at least $100 or, if less, all of your
Account Value. If your remaining Account Value in a Division or Guarantee Period
would be less than $500 as a result of the withdrawal (except for the Money
Market Fund Division), we reserve the right to transfer the remaining balance to
the Money Market Fund Division. We will do this without charge.

We will always pay you the amount of your partial withdrawal request, except
that we may deny your request for a partial withdrawal if it would reduce your
Account Value below $500. The value of your Accumulation Units and Fixed Account
interests that we redeem will equal the amount of the withdrawal request, plus
any applicable Surrender Charge and premium tax. You can also tell us to take
Surrender Charges and income tax from the amount you want withdrawn.

We also make available a systematic withdrawal plan. Under this plan, you may
make automatic partial withdrawals in amounts and at periodic intervals that you
specify. The terms and conditions that apply to other partial withdrawals will
also apply to this plan. You may obtain additional information about how to
establish a systematic withdrawal plan from your sales representative or from us
at the addresses and telephone numbers on the first page of this Prospectus. We
reserve the right to modify or terminate the systematic withdrawal plan at any
time.

The Code imposes a penalty tax on certain premature surrenders or withdrawals.
See the "Federal Income Tax Matters" section for a discussion of this and other
tax implications of total surrenders and systematic and other partial
withdrawals. This section also discusses tax withholding requirements.

All collateral assignees of record must consent to any partial withdrawal.


                  ANNUITY PERIOD AND ANNUITY PAYMENT OPTIONS

ANNUITY COMMENCEMENT DATE

The Annuity Commencement Date may be any day of any month up to the Annuitant's
100th birthday. (Pennsylvania has special limitations that require the Annuity
Commencement Date to be no later than age 90, and as early as age 85.) You may
select the Annuity Commencement Date in the Contract application. You may also
change a previously selected date any time before that date by submitting a
Written request, subject to our approval.

See "Federal Income Tax Matters" for a discussion of the penalties that may
result from distributions before the Annuitant's reaching age 59 1/2 under any
Contract or after April 1 of the year following the calendar year in which the
Annuitant reaches age 70 1/2 under certain Qualified Contracts.

APPLICATION OF OWNER ACCOUNT VALUE

We will automatically apply your Variable Account Value in any Division to
provide Variable Annuity Payments based on that Division and your Fixed Account
Value to provide Fixed Annuity Payments. However, we will apply your Account
Value in different proportions, if you give us Written instructions at least 30
days before the Annuity Commencement Date.

We deduct any applicable state and local premium taxes from the amount of
Account Value that we apply to an Annuity Payment Option. In some cases, we may
deduct a Surrender Charge from the amount we apply. (See "Surrender Charge.")
Subject to any such adjustments, we apply your Variable and Fixed Account Values
to an Annuity Payment Option, as discussed below, as of the end of the Valuation
Period that contains the 10th day before the Annuity Commencement Date.

FIXED AND VARIABLE ANNUITY PAYMENTS

We will determine your first monthly Fixed or Variable Annuity Payment using the
annuity tables in the Contract and the amount of your Account Value that is
applied to provide the Fixed or Variable Annuity Payments.

We determine the amount of each monthly Fixed Annuity Payment thereafter based
on the terms of the Annuity Payment Option selected.

     

                                       20
<PAGE>
 
    


We determine the amount of each monthly Variable Annuity Payment thereafter as
follows:

  .  We convert the Account Value that we apply to provide Variable Annuity
     Payments to a number of Annuity Units. We do this by dividing the amount of
     the first Variable Annuity Payment by the value of an Annuity Unit of a
     Division as of the end of the Valuation Period that includes the 10th day
     before the Annuity Commencement Date. This number of Annuity Units remains
     constant for any Annuitant.

  .  We determine the amount of each subsequent Variable Annuity Payment by
     multiplying the number of Annuity Units by the value of an Annuity Unit as
     of the end of the Valuation Period that contains the 10th day before the
     date of each payment.

  .  If we base the Variable Annuity Payments on more than one Division, we
     perform these calculations separately for each Division.

  .  The value of an Annuity Unit at the end of a Valuation Period is the value
     of the Annuity Unit at the end of the previous Valuation Period, multiplied
     by the net investment factor (see "Variable Account Value") for the
     Valuation Period, with an offset for the 3.5% assumed interest rate used in
     the Contract's annuity tables.

The Contract's annuity tables use a 3.5% assumed interest rate. A Variable
Annuity Payment based on a Division will be greater than the previous month, if
the Division's investment return for the month is at an annual rate greater than
3.5%. Conversely, a Variable Annuity Payment will be less than the previous
month, if the Division's investment return is at an annual rate less than 3.5%.

ANNUITY PAYMENT OPTIONS

Sixty to ninety days before the Scheduled Annuity Commencement Date, we will (1)
notify you that the Contract is scheduled to mature, and (2) request that you
select an Annuity Payment Option.

If you have not selected an Annuity Payment Option ten days before the Annuity
Commencement Date, we will proceed as follows:

  .  We will extend the Annuity Commencement Date to the Annuitant's 100th
     birthday, if the scheduled Annuity Commencement Date is any date before the
     Annuitant's 100th birthday; or

  .  We will pay the Account Value, less any applicable charges and premium
     taxes, in one sum to you, if the scheduled Annuity Commencement Date is the
     Annuitant's 100th birthday.

The procedure just described is different in Pennsylvania because the Annuity
Commencement Date cannot exceed age 90.

The Code imposes minimum distribution requirements on the Annuity Payment Option
you choose in connection with Qualified Contracts. (See "Federal Income Tax
Matters.") We are not responsible for monitoring or advising Owners whether they
are meeting the minimum distribution requirements, unless we have received a
specific Written request to do so.

ELECTION OF ANNUITY PAYMENT OPTION

You may elect an Annuity Payment Option only if the initial annuity payment
meets the following minimum requirements:

  .  where you elect only Fixed or Variable Annuity Payments, the initial
     payment must be at least $100; or

  .  where you elect a combination of Variable and Fixed Annuity Payments, the
     initial payment must be at least $50 on each basis.

If the initial annuity payment falls below these amounts, we will reduce the
frequency of annuity payments. If the initial payment still falls below these
amounts, we will make a single payment to the Annuitant or other properly
designated payee equal to your Account Value. We will deduct any applicable
Surrender Charge, uncollected Annual Contract Fee and premium tax.

You may elect the annuity option that will apply for payments to a Beneficiary,
if you or the Annuitant dies. If you have not made this election, the
Beneficiary may do so within 60 days after your or the Annuitant's death. (See
"Death Proceeds.") Thereafter, the Beneficiary will have all the remaining
rights and powers under the Contract and be subject to all of its terms and
conditions. We will make the

     

                                       21
<PAGE>
 
    


first annuity payment at the beginning of the second month following the month
in which we approve the settlement request. We will credit Annuity Units based
on Annuity Unit Values at the end of the Valuation Period that contains the 10th
day before the beginning of that second month.

When an Annuity Payment Option becomes effective, you must deliver the Contract
to our Home Office, in exchange for a payment contract providing for the option
elected.

We provide information about the relationship between the Annuitant's gender and
the amount of annuity payments, including any requirements for gender-neutral
annuity rates and in connection with certain employee benefit plans under
"Gender of Annuitant" in the Statement. (See "Contents of Statement of
Additional Information.")

AVAILABLE ANNUITY PAYMENT OPTIONS

Each Annuity Payment Option, except Option 5, is available on both a fixed and
variable basis. Option 5 is available on a fixed basis only.

OPTION 1 -- LIFE ANNUITY -- We make annuity payments monthly during the lifetime
of the Annuitant. These payments stop with the last payment due before the death
of the Annuitant. We do not guarantee a minimum number of payments under this
arrangement. For example, the Annuitant or other payee might receive only one
annuity payment, if the Annuitant dies before the second annuity payment.

OPTION 2 -- LIFE ANNUITY WITH 120, 180, OR 240 MONTHLY PAYMENTS CERTAIN -- We
make annuity payments monthly during the lifetime of an Annuitant. In addition,
we guarantee that the Beneficiary will receive monthly payments for the
remainder of the period certain, if the Annuitant dies during that period.

OPTION 3 -- JOINT AND LAST SURVIVOR LIFE ANNUITY -- We make annuity payments
monthly during the lifetime of the Annuitant and another payee and during the
lifetime of the survivor of the two. We stop making payments with the last
payment before the death of the survivor. We do not guarantee a minimum number
of payments under this arrangement. For example, the Annuitant or other payee
might receive only one annuity payment if both die before the second annuity
payment. The election of this option is ineffective if either one dies before
the Annuity Commencement Date. In that case, the survivor becomes the sole
Annuitant, and we do not pay death proceeds because of the death of the other
Annuitant.

OPTION 4 -- PAYMENTS FOR A DESIGNATED PERIOD -- We make annuity payments monthly
to an Annuitant or other properly-designated payee, or at his or her death, to
the Beneficiary, for a selected number of years ranging from five to 40. If this
option is selected on a variable basis, the designated period may not exceed the
life expectancy of the Annuitant or other properly-designated payee.

Under the fourth option, we provide no mortality guarantee, even though we
reduce Variable Annuity Payments as a result of a charge to the Separate Account
that is partially for mortality risks. (See "Charge to the Separate Account.")

A payee receiving Variable (but not Fixed) Annuity Payments under Option 4 can
elect at any time to commute (terminate) the option and receive the current
value of the annuity in a single sum. The current value of an annuity under
Option 4 is the value of all remaining annuity payments, assumed to be level,
discounted to present value at an annual rate of 3.5%. We calculate that value
the next time we determine values after receiving your Written request for
payment. The election of a single sum payment under Option 4 is the only way you
may terminate any Annuity Payment Option once annuity payments have started.

OPTION 5 -- PAYMENTS OF A SPECIFIC DOLLAR AMOUNT -- We pay the amount due in
equal monthly installments of a designated dollar amount until the remaining
balance is less than the amount of one installment. The amount of each
installment may not be less than $125 or more than $200 each year per $1,000 of
the original amount due. If the person receiving these payments dies, we
continue to make the remaining payments to the Beneficiary. Payments under this
option are available on a fixed basis only. To determine the remaining balance
at the end of any month, we decrease the balance at the end of the previous
month by the amount of any installment paid during the month. We then apply, to
the remainder, interest at a rate not less than 3.5% compounded annually. If the
remaining balance at any time is less than the amount of one installment, we
will pay the balance as the final payment under the option.

     

                                       22
<PAGE>
 
    


We reduce Variable Annuity Payments as a result of a charge to the Separate
Account that is partially for mortality risks. (See "Charge to the Separate
Account.")

The Code may treat the election of Option 4 or Option 5 in the same manner as a
surrender of the total Account Value. For tax consequences of such treatment,
see "Federal Income Tax Matters." In addition, the Code may not give tax-
deferred treatment to subsequent earnings.

ALTERNATIVE AMOUNT UNDER FIXED LIFE ANNUITY OPTIONS -- In the case of Fixed
Annuity Payments under one of the first three Annuity Payment Options described
above, we make a special election available. In that case, the Owner (or the
Beneficiary, if the Owner has not elected a payment option) may elect monthly
payments based on single payment immediate fixed annuity rates we offer at that
time. This provision allows the Annuitant or other properly-designated payee to
receive the fixed annuity purchase rate in effect for new single payment
immediate annuity Contracts, if it is more favorable.

In place of monthly payments, you may elect payments on a quarterly, semi-annual
or annual basis. In that case, we determine the amount of each annuity payment
on a basis consistent with that described above for monthly payments.

TRANSFERS

After the Annuity Commencement Date, the Annuitant or other properly designated
payee may make one transfer every 180 days among the available Divisions of the
Separate Account or from the Divisions to a Fixed Annuity Payment Option. We
will assess no charge for the transfer. We do not permit transfers from a Fixed
to a Variable Annuity Payment Option. If a transfer causes the value in any
Division to fall below $500, we reserve the right to transfer the remaining
balance in that Division in the same proportion as the transfer request. We make
transfers effective at the end of the Valuation Period in which we receive the
Written transfer request at our Home Office. We reserve the right to terminate
or restrict transfers at any time.


                                DEATH PROCEEDS

DEATH PROCEEDS BEFORE THE ANNUITY COMMENCEMENT DATE

The death proceeds described below are payable to the Beneficiary under the
Contract if any of the following events occurs before the Annuity Commencement
Date:

  .  the Annuitant dies, and no Contingent Annuitant has been named under a
     Non-Qualified Contract;

  .  the Annuitant dies, and we also receive proof of death of any named
     Contingent Annuitant; or

  .  the Owner (including the first to die in the case of joint Owners) of a
     Non-Qualified Contract dies, regardless of whether the deceased Owner was
     also the Annuitant. (However, if the Beneficiary is the Owner's surviving
     spouse, the surviving spouse may elect to continue the Contract as
     described later in this section).

The death proceeds, before deduction of any premium taxes and other applicable
taxes, will equal the greatest of:

  .  the sum of all net purchase payments made (less any premium taxes and other
     applicable taxes we deducted previously and all prior partial withdrawals);

  .  the Owner's Account Value as of the end of the Valuation Period in which we
     receive, at our Home Office, proof of death and the Written request as to
     the manner of payment; or

  .  the "highest anniversary value" before the date of death, as defined below.

The highest anniversary  value before the date of death will be determined as
follows:

  (a) First, we will calculate the Account Values at the end of each of the past
      Contract Anniversaries that occurs before the deceased's 81st birthday.
      (We will thereafter use only the highest of the Contract Anniversary
      Account Values that occurred before the deceased's 81st birthday.);

  (b) Second, we will increase each of the Account Values by the amount of net
      purchase payments the Owner has made since the end of such Contract Years;
      and

     

                                       23
<PAGE>
 
    


  (c) Third, we will reduce the result by the amount of any withdrawals the
      Owner has made since the end of such Contract Years.

      The highest anniversary value will be an amount equal to the highest of
      such values. Net purchase payments are purchase payments less applicable
      taxes deducted at the time the purchase payment is made.

The death proceeds become payable to the Beneficiary when we receive:

  .  proof of the Owner's or Annuitant's death, and

  .  a Written request from the Beneficiary specifying the manner of payment.

If the Owner has not already done so, the Beneficiary may, within 60 days after
the date the death proceeds become payable, elect to receive the death proceeds
as (1) a single sum or (2) in the form of one of the Annuity Payment Options
provided in the Contract. (See "Annuity Payment Options.") If we do not receive
a request specifying the manner of payment, we will make a single sum payment,
based on values we determine at that time.

If the Owner (including the first to die if there are joint Owners) under a Non-
Qualified Contract dies before the Annuity Commencement Date, we will distribute
all amounts payable under the Contract in accordance with the following rules:

  .  We will distribute all amounts:

     (a) within five years of the date of death, or

     (b) if the Beneficiary elects, as annuity payments, beginning within one
         year of the date of death and continuing over a period not extending
         beyond the life or life expectancy of the Beneficiary.

  .  If the Beneficiary is the Owner's surviving spouse, the spouse may elect to
     continue the Contract as the new Owner. If the original Owner was the
     Annuitant, the surviving spouse may also elect to become the new Annuitant.

  .  If the Owner is not a natural person, these distribution requirements apply
     at the death of the primary Annuitant, within the meaning of the Code.
     Under a parallel section of the Code, similar requirements apply to
     retirement plans for which we issue Qualified Contracts.

Failure to satisfy the requirements described in this Section may result in
serious adverse tax consequences.

DEATH PROCEEDS AFTER THE ANNUITY COMMENCEMENT DATE

If the Annuitant dies on or after the Annuity Commencement Date, the amounts
payable to the Beneficiary or other properly designated payee are any continuing
payments under the Annuity Payment Option in effect. (See "Annuity Payment
Options.") In such case, the payee will:

  .  have all the remaining rights and powers under a Contract, and

  .  be subject to all the terms and conditions of the Contract.

Also, if the Annuitant dies on or after the Annuity Commencement Date, no
previously named Contingent Annuitant can become the Annuitant.

If the payee under a Non-Qualified Contract dies after the Annuity Commencement
Date, we will distribute any remaining amounts payable under the terms of the
Annuity Payment Option at least as rapidly as under the method of distribution
in effect when the payee dies. If the payee is not a natural person, this
requirement applies upon the death of the primary Annuitant, within the meaning
of the Code.

Under a parallel section of the Code, similar requirements apply to retirement
plans for which we issue Qualified Contracts.

Failure to satisfy requirements described in this section may result in serious
adverse tax consequences.

PROOF OF DEATH

We accept the following as proof of any person's death:

  .  a  certified death certificate;

  .  a certified decree of a court of competent jurisdiction as to the finding
     of death;

  .  a written statement by a medical doctor who attended the deceased at the
     time of death; or

  .  any other proof satisfactory to us.

Once we have paid the death proceeds, the Contract terminates, and our
obligations are complete.

                          CHARGES UNDER THE CONTRACTS

PREMIUM TAXES

When applicable, we will deduct premium taxes imposed by certain states. We may
deduct such amount either at the time the tax is imposed or later. We may deduct
the amount as follows:

  .  from purchase payment(s) when received;

  .  from the Owner's Account Value at the time annuity payments begin;

  .  from the amount of any partial withdrawal; or

  .  from proceeds payable upon termination of the Contract for any other
     reason, including death of the Owner or Annuitant, or surrender of the
     Contract.

If premium tax is paid, AGL may reimburse itself for the tax when making the
deduction under the second, third, and fourth items on the list immediately
above, by multiplying the sum of Purchase Payments being withdrawn by the
applicable premium tax percentage.

Applicable premium tax rates depend upon the Owner's then-current place of
residence. Applicable rates currently range from 0% to 3.5%. The rates are
subject to change by legislation, administrative interpretations, or judicial
acts. We will not make a profit on this charge.

SURRENDER CHARGE

The Surrender Charge reimburses us for part of our expenses in distributing the
Contracts. We believe, however, that the amount of our expenses will exceed the
amount of revenues generated by the Surrender Charge. We will pay for extra
expenses out of our general surplus, which might include profits from the charge
for the assumption of mortality and expense risks.

Unless a withdrawal is exempt from the Surrender Charge (as discussed below),
the Surrender Charge is a percentage of the amount of each purchase payment that
you withdraw during the first seven years after we receive that purchase
payment. The percentage declines depending on how many years have passed since
we originally credited the withdrawn purchase payment to your Account Value, as
follows:

                                           SURRENDER CHARGE AS A
     YEAR OF PURCHASE                      PERCENTAGE OF PURCHASE
     PAYMENT WITHDRAWAL                       PAYMENT WITHDRAWN
     ------------------                    ----------------------
     1st................................            7%
     2nd................................            6%
     3rd................................            5%
     4th................................            5%
     5th................................            4%
     6th................................            3%
     7th................................            2%
     Thereafter.........................            0%

In computing the Surrender Charge, we deem withdrawals from your Account Value
to consist first of purchase payments, in order of contribution, followed by any
amounts in excess of purchase payments. The Surrender Charge will apply to the
following transactions, which we consider to be withdrawals:

  .  total surrender;

  .  partial withdrawal;

  .  commencement of an Annuity Payment Option; and

  .  termination due to insufficient Account Value.

The Surrender Charge will NOT apply to withdrawals in the following
circumstances:

  .  the amount of withdrawals that exceeds the cumulative amount of your
     purchase payments;

  .  death of the Annuitant, at any age, after the Annuity Commencement Date;

  .  death of the Annuitant, at any age, before the Annuity Commencement Date,
     provided no Contingent Annuitant survives;

  .  death of the Owner, including the first to die in the case of joint Owners
     of a Non-Qualified Contract, unless the Contract continues under the
     special rule for a surviving spouse;

  .  annuitization over at least ten years, or life contingent annuitization
     where the life expectancy is at least ten years;

  .  within the 30-day window under the One-Time Reinstatement Privilege;

     

                                       25
<PAGE>
 
    


  .  the Annuitant is confined to a long-term care facility or is subject to a
     terminal illness (see "Long-Term Care and Terminal Illness");

  .  the portion of your first withdrawal or total surrender in any Contract
     Year that does not exceed 10% of the amount of your purchase payments that
     (1) have not previously been withdrawn and (2) have been credited to the
     Contract for at least one year. (If you make multiple withdrawals during a
     Contract Year, we will recalculate the amount eligible for the free
     withdrawal at the time of each withdrawal. After the first Contract Year,
     you may make non-automatic and automatic withdrawals in the same Contract
     Year subject to the 10% limitation. For withdrawals under a systematic
     withdrawal plan, Purchase Payments credited for 30 days or more are
     eligible for the 10% free withdrawal); and

  .  any amounts withdrawn that are in excess of the amount permitted by the 10%
     free withdrawal privilege, described above, if you are withdrawing the
     amounts to obtain or retain favorable tax treatment. (For example, under
     certain circumstances the income and estate tax benefits of a charitable
     remainder trust may be available only if you withdraw assets from a
     Contract funding the trust more rapidly than the 10% free withdrawal
     privilege permits. This exception is subject to our approval.)

We do not consider a free withdrawal under any of the foregoing Surrender Charge
exceptions to be a withdrawal of purchase payments, except for purposes of
computing the 10% free withdrawal described in the preceding paragraph. The Code
may impose a penalty on distributions if the recipient is under age 59 1/2. (See
"Penalty Tax on Premature Distributions.")

SPECIAL SURRENDER CHARGE RULES
FOR CONTRACTS BOUGHT AFTER OCTOBER 1, 1998

The 10% free withdrawal privilege discussed above is a 15% free withdrawal
privilege if you bought your Contract after October 1, 1998. The affected
discussion follows using "15%" in place of "10%."

The Surrender Charge will NOT apply to withdrawals in the following
circumstances, if you bought your Contract after October 1, 1998:

  .  the portion of your first withdrawal or total surrender in any Contract
     Year that does not exceed 15% of the amount of your purchase payments that
     (1) have not previously been withdrawn and (2) have been credited to the
     Contract for at least one year. (If you make multiple withdrawals during a
     Contract Year, we will recalculate the amount eligible for the free
     withdrawal at the time of each withdrawal. After the first Contract Year,
     you may make non-automatic and automatic withdrawals in the same Contract
     Year subject to the 15% limitation. For withdrawals under a systematic
     withdrawal plan, Purchase Payments credited for 30 days or more are
     eligible for the 15% free withdrawal); and

  .  any amounts withdrawn that are in excess of the amount permitted by the 15%
     free withdrawal privilege, described above, if you are withdrawing the
     amounts to obtain or retain favorable tax treatment. (For example, under
     certain circumstances the income and estate tax benefits of a charitable
     remainder trust may be available only if you withdraw assets from a
     Contract funding the trust more rapidly than the 15% free withdrawal
     privilege permits. This exception is subject to our approval.)

We do not consider a free withdrawal under any of the foregoing Surrender Charge
exceptions to be a withdrawal of purchase payments, except for purposes of
computing the 15% free withdrawal described in the preceding paragraph. The Code
may impose a penalty on distributions if the recipient is under age 59 1/2. (See
"Penalty Tax on Premature Distributions.")

Upon selection of an Annuity Payment Option that does not qualify for a
Surrender Charge exception above, we use the amount payable to the Owner upon
full surrender of a Contract (see "Surrenders") to pay for the Annuity Payment
Option.

TRANSFER CHARGES

We describe the charges to pay the expense of making transfers under
"Transfer, Automatic Rebalancing, Surrender and Partial Withdrawal of Owner
Account Value--Transfers" and "Annuity Period and Annuity Payment
Options--Transfers." These charges are not designed to yield a profit.

ANNUAL CONTRACT FEE

We will deduct an Annual Contract Fee of $35 from your Account Value at the end
of each Contract Year before the Annuity Commencement Date. (The Fee is $30 for
Contracts issued in the State of North Dakota.) This Fee is for administrative
expenses (which do not include expenses of distributing the Contracts). We do
not expect the revenues we derive from this Fee to exceed the expenses. Unless
paid directly, the Fee will be allocated among the Guarantee Period and
Divisions in proportion to your Account Value in each. We will deduct the entire
Fee for the year from the proceeds of any full surrender. We reserve the right
to waive the Fee.

CHARGE TO THE SEPARATE ACCOUNT

We deduct from Separate Account assets a daily charge at an annualized rate of
1.40% of the average daily net asset value of the Separate Account attributable
to the Contracts. This charge (1) offsets administrative expenses not covered by
the Annual Contract Fee discussed above and (2) compensates us for assuming
mortality and expense risks under the Contracts. The 1.40% charge divides into
 .15% for administrative expenses and 1.25% for the assumption of mortality and
expense risks.

We do not expect to earn a profit on that portion of the charge that is for
administrative expenses. However, we do expect to derive a profit from the
portion that is for the assumption of mortality and expense risks. There is no
necessary relationship between the amount of administrative charges deducted for
a given Contract and the amount of expenses actually attributable to that
Contract.

In assuming the mortality risk, we incur the risks that:

  .  our actuarial estimate of mortality rates may prove erroneous,

  .  Annuitants will live longer than expected, and

  .  more Owners or Annuitants than expected will die at a time when the death
     benefit we guarantee is higher than the net surrender value of their
     interests in the Contracts.

In assuming the expense risk, we incur the risk that the revenues from the
expense charges under the Contracts (charges that we guarantee will not
increase) will not cover our expense of administering the Contracts.

MISCELLANEOUS

Each Series pays charges and expenses out of its assets. The prospectus for each
Series describes the charges and expenses. We reserve the right to impose
charges or establish reserves for any federal or local taxes that we incur today
or may incur in the future and that we deem attributable to the Contracts.

SYSTEMATIC WITHDRAWAL PLAN

You may make automatic partial withdrawals, at periodic intervals, through a
systematic withdrawal program. Minimum payments are $100. You may choose from
payment schedules of monthly, quarterly, semi-annual, or annual payments. You
may start, stop, increase, or decrease payments. You may elect to (1) start
withdrawals as early as 30 days after the issue date of the Contract and (2)
take withdrawals from the Fixed Account or any Division. Systematic withdrawals
are subject to the terms and conditions applicable to other partial withdrawals,
including Surrender Charges and exceptions to Surrender Charges.

ONE-TIME REINSTATEMENT PRIVILEGE

If the Account Value is at least $500, you may elect to reinvest all of the
proceeds that you liquidated from the Contract within the previous 30 days. In
this case, we will credit the Surrender Charge and the Annual Contract Fee, if a
new Annual Contract Fee is not then due, back to the Contract. We will reinvest
the proceeds at the value we next compute following the date of receipt of the
proceeds. Unless you request otherwise, we will allocate the proceeds among the
Divisions and Guarantee Periods in the same proportions as before surrender. We
will compute any subsequent Surrender Charge as if we had issued the Contract at
the date of reinstatement for a purchase payment in the amount of the net
surrender proceeds. You may use this privilege only once.

     

                                       27
<PAGE>
 
    


This privilege is not available under Contracts purchased in Oregon.

REDUCTION IN SURRENDER CHARGES OR ADMINISTRATIVE CHARGES

We may reduce the Surrender Charges or administrative charges imposed under
certain Qualified Contracts for employer sponsored plans. Any such reductions
will reflect differences in costs or services and will not be unfairly
discriminatory as to any person. Differences in costs and services result from
factors such as reduced sales expenses or administrative efficiencies relating
to serving a large number of employees of a single employer and functions
assumed by the employer that we otherwise would have to perform.


                     LONG-TERM CARE AND TERMINAL ILLNESS 

The rider we describe below is not available in all states. You should ask your
sales representative or our Home Office to tell you if it applies to you. There
is no separate charge for this rider.

LONG-TERM CARE

We describe long-term care in a special Contract rider. No Surrender Charge will
apply to a partial withdrawal or total surrender made during any period of time
that the Annuitant is confined continuously for 30 days or more (or within 30
days after discharge) in a hospital or state-licensed in-patient nursing
facility. You must give us Written proof of such confinement.

TERMINAL ILLNESS

The same rider provides that no Surrender Charge will apply to a partial
withdrawal or total surrender if you give us a physician's Written certification
that the Annuitant is terminally ill and not expected to live more than twelve
months. We must waive or exercise our right to a second physician's opinion.


                        OTHER ASPECTS OF THE CONTRACTS

Only an officer of AGL can agree to change or waive the provisions of any
Contract. The Contracts are non-participating, which means they are not entitled
to share in any dividends, profits or surplus of AGL.

OWNERS, ANNUITANTS, AND BENEFICIARIES; ASSIGNMENTS

You, as the Owner of a Contract, will be the same as the Annuitant, unless you
choose a different Annuitant when you purchase a Contract. In the case of joint
ownership, both Owners must join in the exercise of any rights or privileges
under the Contract. You choose the Annuitant and any Contingent Annuitant in the
application for a Contract and may not change that choice.

You choose the Beneficiary and any Contingent Beneficiary when you purchase a
Contract. You may change a Beneficiary or Contingent Beneficiary before the
Annuity Commencement Date, while the Annuitant is still alive. The payee may
make this change after the Annuity Commencement Date.

We will make any designation of a new Beneficiary or Contingent Beneficiary
effective as of the date it is signed. However, the change in designation will
not affect any payments we make or action we take before we receive the Written
request. We also need the Written consent of any irrevocably-named Beneficiary
or Contingent Beneficiary before we make a change. Under certain retirement
programs, the law may require spousal consent to name or change a Beneficiary to
a person other than the spouse. We are not responsible for the validity of any
designation of a Beneficiary or Contingent Beneficiary.

If the Beneficiary or Contingent Beneficiary is not living at the time we are to
make any payment, you as the Owner will be the Beneficiary. If you are not then
living, your estate will be the Beneficiary.

Owners and other payees may assign their rights under Qualified Contracts only
in certain narrow circumstances referred to in the Contracts. Owners and other
payees may assign their rights under Non-Qualified Contracts, including their
ownership rights. We take no responsibility for the validity of any assignment.
Owners must make a change in ownership rights in Writing and send a copy to our
Home Office. We will make the change effective on the date it was made. However,
we are not bound by a change until the date we record it. The rights under a
Contract are

     

                                       28
<PAGE>
 
    


subject to any assignment of record at our Home Office. An assignment or pledge
of a Contract may have adverse tax consequences. (See "Federal Income Tax
Matters.")

REPORTS

We will mail to Owners (or anyone receiving payments following the Annuity
Commencement Date), any reports and communications required by applicable law.
We will mail to the last known address of record. You should give us prompt
written notice of any address change.

RIGHTS RESERVED BY US

Upon notice to the Owner, we may modify a Contract to the extent necessary to:

  .  reflect a change in the Separate Account or any Division;

  .  create new separate accounts;

  .  operate the Separate Account in any form permitted under the 1940 Act or in
     any other form permitted by law;

  .  transfer any assets in any Division to another Division, or to one or more
     separate accounts, or the Fixed Account;

  .  add, combine or remove Divisions in the Separate Account, or combine the
     Separate Account with another separate account;

  .  add, restrict or remove Guarantee Periods of the Fixed Account;

  .  make any new Division available to you on a basis we determine;

  .  substitute, for the shares held in any Division, the shares of another
     Series or the shares of another investment company or any other investment
     permitted by law;

  .  make any changes required by the Code or by any other law, regulation or
     interpretation to continue treatment of the Contract as an annuity;

  .  commence deducting premium taxes or adjust the amount of premium taxes
     deducted in accordance with state law that applies; or

  .  make any changes required to comply with the rules of any Series.

When required by law, we will obtain (1) your approval of changes and (2) the
approval of any appropriate regulatory authority.

PAYMENT AND DEFERMENT

We will normally pay amounts surrendered or withdrawn from a Contract within
seven calendar days after the end of the Valuation Period in which we receive
the Written surrender or withdrawal request at our Home Office. A Beneficiary
may request the manner of payment of death proceeds within 60 days after the
death proceeds become payable. If we do not receive a Written request specifying
the manner of payment, we will pay the death benefit as a single sum, normally
within seven calendar days after the end of the Valuation Period that contains
the last day of the 60 day period. We reserve the right, however, to defer
payments or transfers out of the Fixed Account for up to six months. Also, we
reserve the right to defer payment of that portion of your Account Value that is
attributable to a purchase payment made by check for a reasonable period of time
(not to exceed 15 days) to allow the check to clear the banking system.

Finally, we reserve the right to defer payment of any surrender, annuity
payment, or death proceeds out of the Variable Account Value if:

  .  the New York Stock Exchange is closed other than customary weekend and
     holiday closings, or trading on the New York Stock Exchange is restricted
     as determined by the SEC;

  .  the SEC determines that an emergency exists, as a result of which disposal
     of securities held in a Division is not reasonably practicable or it is not
     reasonably practicable to fairly determine the Variable Account Value; or

  .  the SEC by order permits the delay for the protection of Owners.

We may also postpone transfers and allocations of Account Value among the
Divisions and the Fixed Account under these circumstances.

                          FEDERAL INCOME TAX MATTERS

GENERAL

We cannot comment on all of the federal income tax consequences associated with
the Contracts. Federal income tax law is complex. Its application to a
particular person may vary according to facts peculiar to the person.
Consequently, we do not intend for you to take this discussion as tax advice.
You should consult with a competent tax adviser before purchasing a Contract.

We base this discussion on our understanding of the law, regulations and
interpretations existing on the date of this Prospectus. Congress, in the past,
has enacted legislation changing the tax treatment of annuities in both the
Qualified and the Non-Qualified markets and may do so again in the future. The
Treasury Department may issue new or amended regulations or other
interpretations of existing tax law. The courts may also interpret the tax law
in ways that affect the tax treatment of annuities. Any such change could have a
retroactive effect. We suggest that you consult your legal or tax adviser on
these issues.

The discussion does not address federal estate and gift tax, or social security
tax, or any state or local tax consequences associated with the Contracts.

NON-QUALIFIED CONTRACTS

PURCHASE PAYMENTS.  Purchasers of a Contract that does not qualify for special
tax treatment and is "Non-Qualified" may not deduct from their gross income the
amount of purchase payments made.

TAX DEFERRAL BEFORE ANNUITY COMMENCEMENT DATE. Owners who are natural persons
are not taxed currently on (1) increases in their Account Value resulting from
interest earned in the Fixed Account, or (2) the investment experience of the
Separate Account so long as the Separate Account complies with certain
diversification requirements. These requirements mean that the Separate Account
must invest in Series that are "adequately diversified" in accordance with
Treasury Department regulations. We do not control the Series, but we have
received commitments from the investment advisers to the Series to use their
best efforts to operate the Series in compliance with these diversification
requirements. A Contract investing in a Series that failed to meet the
diversification requirements would subject Owners to current taxation of income
in the Contract for the period of such diversification failure (and any
subsequent period). Income means the excess of the Account Value over the
Owner's investment in the Contract (discussed below).

Control over allocation of values among different investment alternatives may
cause Owners or persons receiving annuity payments to be treated as the owners
of the Separate Account's assets for tax purposes. However, current regulations
do not provide guidance as to how to avoid this result. We reserve the right to
amend the Contracts in any way necessary to avoid this result. The Treasury
Department has stated that it may establish standards through regulations or
rulings. These standards may apply only prospectively, although they could apply
retroactively if the Treasury Department considers the standards not to reflect
a new position.

Owners that are not natural persons -- that is, Owners such as corporations --
are taxed currently on annual increases in their Account Value, unless an
exception applies. Exceptions apply for, among other things, Owners that are not
natural persons but that hold a Contract as an agent for a natural person.

TAXATION OF ANNUITY PAYMENTS.  Part of each annuity payment received after the
Annuity Commencement Date is excludible from gross income.

In the case of Fixed Annuity Payments, the excludible portion is found by
multiplying:

  .  the amount paid by,

  .  the ratio of the investment in the Contract (discussed below) to the
     expected return under the Fixed Annuity Payment Option.

In the case of Variable Annuity Payments, the excludible portion is the
investment in the Contract divided by the number of expected payments.

In both cases, the remaining portion of each annuity payment, and all payments
made after the investment in the Contract has been reduced to zero, are included
in the payee's income. Should annuity payments stop on account of the death of
the Annuitant before the investment in the Contract has been fully paid out, the
payee is allowed a deduction for the unpaid amount. If the payee is the
Annuitant, the deduction is taken on the final tax return. If the payee is a
Beneficiary, that

     

                                       30
<PAGE>
 
    


Beneficiary may receive the balance of the total investment as payments are made
or on the Beneficiary's final tax return. An Owner's "investment in the
Contract" is the amount equal to the portions of purchase payments made by or on
behalf of the Owner that have not been excluded or deducted from the
individual's gross income, less amounts previously received under the Contract
that were not included in income.

TAXATION OF PARTIAL WITHDRAWALS AND TOTAL SURRENDERS.  Partial withdrawals from
a Contract are includible in income to the extent that the Owner's Account Value
exceeds the investment in the Contract. In the event you surrender a Contract in
its entirety, the amount of your investment in the Contract is excludible from
income, and any amount you receive in excess of your investment in the Contract
is includible in income. All annuity Contracts or Contracts we issue to the same
Owner during any calendar year are aggregated for purposes of determining the
amount of any distribution that is includible in gross income.

PENALTY TAX ON PREMATURE DISTRIBUTIONS.  In the case of such a distribution,
there may be imposed a federal tax penalty equal to 10% of the amount treated as
taxable income. The penalty tax will not apply, however, to distributions:

  .  made on or after the recipient reaches age 59 1/2,

  .  made on account of the recipient's becoming disabled,

  .  that are made after the death of the Owner before the Annuity Commencement
     Date or of the payee after the Annuity Commencement Date (or if such person
     is not a natural person, that are made after the death of the primary
     Annuitant, as defined in the Code); or

  .  that are part of a series of substantially equal periodic payments made
     at least annually over the life (or life expectancy) of the Annuitant
     or the joint life (or joint life expectancies) of the Annuitant and the
     Beneficiary, provided such payments are made for a minimum of 5 years
     and the distribution method is not changed before the recipient reaches age
     59 1/2 (except in the case of death or disability).

Premature distributions may result from an early Annuity Commencement Date, an
early surrender, partial withdrawal from or assignment of a Contract, or the
early death of an Annuitant, unless the third clause listed above applies.

PAYMENT OF DEATH PROCEEDS.  Special rules apply to the distribution of any death
proceeds payable under the Contract. (See "Death Proceeds.")

ASSIGNMENTS AND LOANS.  An assignment, loan, or pledge under a Non-Qualified
Contract is taxed in the same manner as a partial withdrawal, as described
above. Repayment of a loan or release of an assignment or pledge is treated as a
new purchase payment.

INDIVIDUAL RETIREMENT ANNUITIES ("IRAs")

PURCHASE PAYMENTS.  Individuals who are not active participants in a tax
qualified retirement plan may, in any year, deduct from their taxable income
purchase payments for an IRA equal to the lesser of $2,000 or 100% of the
individual's earned income. In the case of married individuals filing a joint
return, the deduction will, in general, be the lesser of $4,000 or 100% of the
combined earned income of both spouses, reduced by any deduction for an IRA
purchase payment allowed to the spouse. Single persons who participate in a tax-
qualified retirement plan and who have adjusted gross income not in excess of
$31,000 may fully deduct their IRA purchase payments. Those who have adjusted
gross income in excess of $41,000 will not be able to deduct purchase payments.
For those with adjusted gross income in the range between $31,000 and $41,000,
the deduction decreases to zero, based on the amount of income. Beginning in
2000, that income range will increase, as follows:

Similarly, the otherwise deductible portion of an IRA purchase payment will be
phased out, in the case of married individuals filing joint tax returns, with
adjusted gross income between $51,000 and $61,000, and in the case of married
individuals filing separately, with adjusted gross income between $0 and
$10,000. (A husband and wife who file separate returns and live apart at all
times during the taxable year are not treated as married individuals.) Beginning
in 2000, the income range over which the otherwise deductible

</TABLE>

A married individual filing a joint tax return, who is not an active participant
in a tax-qualified retirement plan, but whose spouse is an active participant in
such a plan, may, in any year, deduct from his or her taxable income purchase
payments for an IRA equal to the lesser of $2,000 or 100% of the individual's
earned income. For the individual, the adjusted gross income range over which
the otherwise deductible portion of an IRA purchase payment will be phased out
is $150,000 to $160,000.

TAX FREE ROLLOVERS.  Amounts may be transferred, in a tax-free rollover, from
(1) a tax-qualified plan to an IRA or (2) from one IRA to another IRA if, the
transfer meets certain conditions. All taxable distributions ("eligible rollover
distributions") from tax qualified plans are eligible to be rolled over with the
exception of:

  .  annuities paid over a life or life expectancy,

  .  installments for a period of ten years or more; and

  .  required minimum distributions under Section 401(a)(9) of the Code.

Rollovers may be accomplished in two ways. First, we may pay an eligible
rollover distribution directly to an IRA (a "direct rollover"). Second, we may
pay the distribution directly to the Annuitant and then, within 60 days of
receipt, the Annuitant may roll the amount over to an IRA. However, any amount
that was not distributed as a direct rollover will be subject to 20% income tax
withholding.

DISTRIBUTIONS FROM AN IRA.  Amounts received under an IRA as annuity payments,
upon partial withdrawal or total surrender, or on the death of the Annuitant,
are included in the Annuitant's or other recipients' income. If nondeductible
purchase payments have been made, a pro rata portion of such distributions may
not be includible in income. A 10% penalty tax is imposed on the amount
includible in gross income from distributions that occur before the Annuitant
reaches age 59 1/2 and that are not made on account of death or disability, with
certain exceptions. These exceptions include:

  .  distributions that are part of a series of substantially equal periodic
     payments made at least annually over the life (or life expectancy) of the
     Annuitant or the joint lives (or joint life expectancies) of the Annuitant
     and the Beneficiary; provided such payments are made for a minimum of 5
     years and the distribution method is not changed before the recipient
     reaches age 59 1/2 (except in the case of death or disability),

  .  distributions for medical expenses in excess of 7.5% of the Annuitant's
     adjusted gross income and withdrawals for medical insurance (without regard
     to the 7.5% AGI floor) if the individual has received unemployment
     compensation under federal or state law for at least 12 consecutive weeks
     under certain conditions,

  .  distributions for qualified first-time home purchases for the individual, a
     spouse, children, grandchildren, or ancestor of the individual or the
     individual's spouse, subject to a $10,000 lifetime maximum; and

  .  distributions for higher education expenses for the individual, a spouse,
     children, or grandchildren.

Distributions of minimum amounts required by the Code must commence by April 1
of the calendar year following the calendar year in which the Annuitant reaches
age 70 1/2 or retires (whichever is later). Additional distribution rules apply
after the death of the Annuitant. These rules are similar to those governing
distributions on the death of an Owner (or other payee during the Annuity
Period) under a Non-Qualified Contract. (See "Death Proceeds.") Failure to
comply with the minimum distribution rules will result in a penalty tax of 50%
of the amount by which the minimum distribution required exceeds the actual
distribution.

ROTH IRAs

Beginning in 1998, individuals may purchase a new type of non-deductible IRA,
known as a Roth IRA. Purchase payments for a Roth IRA are limited to $2,000 per
year. This permitted contribution is phased out for adjusted gross income
between $95,000 and $110,000 in the case of single taxpayers, between

     

                                       32
<PAGE>
 
    


$150,000 and $160,000 in the case of married taxpayers filing joint returns, and
between $0 and $10,000 in the case of married taxpayers filing separately. An
overall $2,000 annual limitation continues to apply to all of a taxpayer's IRA
contributions, including Roth IRAs and non-Roth IRAs.

An individual may make a rollover contribution from a non-Roth IRA to a Roth
IRA, unless the individual has adjusted gross income over $100,000 or the
individual is a married taxpayer filing a separate return. The individual must
pay tax on any portion of the IRA being rolled over that represents income or a
previously deductible IRA contribution. There are no similar limitations on
rollovers from a Roth IRA to another Roth IRA.

Qualified distributions from Roth IRAs are entirely tax-free. A qualified
distribution requires that (1) the individual has held the Roth IRA for at least
five years and (2) the distribution is made either after the individual reaches
age 59 1/2, on the individual's death or disability, or as qualified first-time
home purchase. Qualified Distributions for a qualified first-time home purchase,
are subject to a $10,000 lifetime maximum for the individual, a spouse, child,
grandchild, or ancestor of such individual or the individual's spouse.

SIMPLIFIED EMPLOYEE PENSION PLANS

Eligible employers may establish an IRA plan known as a simplified employee
pension plan ("SEP"), if certain requirements are met. An employee may make
contributions to a SEP in accordance with the rules applicable to IRAs discussed
above. Employer contributions to an employee's SEP are deductible by the
employer and are not currently includible in the taxable income of the employee,
provided that total employer contributions do not exceed the lesser of 15% of an
employee's compensation or $30,000.

SIMPLE RETIREMENT ACCOUNTS

Eligible employers may establish an IRA plan known as a simple retirement
account ("SRA"), if they meet certain requirements. Under an SRA, the employer
contributes elective employee compensation deferrals up to a maximum of $6,000 a
year to the employee's SRA. The employer must, in general, make a fully vested
matching contribution for employee deferrals up to a maximum of 3% of
compensation.

OTHER QUALIFIED PLANS

PURCHASE PAYMENTS.  Purchase payments made by an employer under a pension,
profit sharing, or annuity plan qualified under Section 401 or 403(a) of the
Code, not in excess of certain limits, are deductible by the employer. The
purchase payments are also excluded from the current income of the employee.

DISTRIBUTIONS BEFORE THE ANNUITY COMMENCEMENT DATE.  Purchase payments
includible in an employee's taxable income (less any amounts previously received
that were not includible in the employee's taxable income) represent the
employee's "investment in the Contract." Amounts received before the Annuity
Commencement Date under a Contract in connection with a Section 401 or 403(a)
plan are generally allocated on a pro-rata basis between the employee's
investment in the Contract and other amounts. A lump-sum distribution will not
be includible in income in the year of distribution, if the employee transfers,
within 60 days of receipt, all amounts received (less the employee's investment
in the Contract), to another tax-qualified plan, to an individual retirement
account or an IRA in accordance with the rollover rules under the Code.

However, any amount that is not distributed as a direct rollover will be subject
to 20% income tax withholding. (See "Tax Free Rollovers.") Special tax treatment
may be available, for tax years beginning before December 31, 1999, in the case
of certain lump-sum distributions that are not rolled over to another plan or
IRA.

A 10% penalty tax is imposed on the amount includible in gross income from
distributions that occur before the employee reaches age 59 1/2 and that are not
made on account of death or disability, with certain exceptions. These
exceptions include distributions that are:

  .  part of a series of substantially equal periodic payments made at least
     annually beginning after the employee separates from service and made over
     the life (or life expectancy) of the employee or the joint lives (or joint
     life expectancies) of the employee and the Beneficiary, provided such
     payments are made for at least 5 years and the distribution method is not
     changed before the recipient reaches age 59 1/2 (except in the case of
     death or disability),

     

                                       33
<PAGE>
 
    


  .  made after the employee's separation from service on account of early
     retirement after attaining age 55,

  .  made to pay for qualified higher education or first-time home buyer
     expenses,

  .  made to an alternate payee pursuant to a qualified domestic relations
     order, if the alternate payee is the spouse or former spouse of the
     employee; or

  .  distributions for medical expenses in excess of 7.5% of the Annuitant's
     adjusted gross income and withdrawals for medical insurance (without regard
     to the 7.5% AGI floor) if the individual has received unemployment
     compensation under federal or state law for at least 12 consecutive weeks
     under certain conditions.

ANNUITY PAYMENTS.  A portion of annuity payments received under Contracts
for Section 401 and 403(a) plans after the Annuity Commencement Date may
be excludible from the employee's income, in the manner discussed above,
in connection with Variable Annuity Payments, under "Non-Qualified Contracts --
Taxation of Annuity Payments." The difference is that, here, the number of
expected payments is determined under a provision in the Code. Distributions
of minimum amounts required by the Code generally must commence by April 1 of
the calendar year following the calendar year in which the employee reaches age
70 1/2 (or retires, if later). Failure to comply with the minimum distribution
rules will result in a penalty tax of 50% of the amount by which the minimum
distribution required exceeds the actual distribution.

SELF-EMPLOYED INDIVIDUALS.  Various special rules apply to tax-qualified plans
established by self-employed individuals.

PRIVATE EMPLOYER UNFUNDED DEFERRED COMPENSATION PLANS

PURCHASE PAYMENTS.  Private taxable employers may establish unfunded, Non-
Qualified deferred compensation plans for a select group of management or highly
compensated employees and/or for independent contractors. To avoid current
taxation these benefits must be subject to a substantial risk of forfeiture.

These types of programs allow individuals to defer (1) receipt of up to 100% of
compensation that would otherwise be includible in income and (2) payment of
federal income taxes on the amounts.

Deferred compensation plans represent a contractual promise on the part of the
employer to pay current compensation at some future time. The Contract is owned
by the employer and is subject to the claims of the employer's creditors. The
individual has no right or interest in the Contract and is entitled only to
payment from the employer's general assets in accordance with plan provisions.
Purchase payments are not currently deductible by the employer until benefits
are included in the taxable income of the employee.

TAXATION OF DISTRIBUTIONS.  Amounts that an individual receives from a private
employer deferred compensation plan are includible in gross income for the
taxable year in which such amounts are paid or otherwise made available.

FEDERAL INCOME TAX WITHHOLDING AND REPORTING

Amounts distributed from a Contract, to the extent includible in taxable income,
are subject to federal income tax withholding.

In some cases, if you own more than one Qualified annuity contract, the
contracts may be considered together to determine whether the federal tax law
requirement for minimum distributions after age 70 1/2, or retirement in
appropriate circumstances, has been satisfied. You may rely on distributions
from another annuity contract or Contract to satisfy the minimum distribution
requirement under a Qualified Contract we issued. However, you must sign a
waiver releasing us from any liability to you for not calculating and reporting
the amount of taxes and penalties payable for failure to make required minimum
distributions under the Contract.

TAXES PAYABLE BY AGL AND THE SEPARATE ACCOUNT

AGL is taxed as a life insurance company under the Code. The operations of the
Separate Account are part of the total operations of AGL and are not taxed
separately. Under existing federal income tax laws, AGL is not taxed on
investment income derived by the Separate Account (including realized and
unrealized capital gains) with respect to the Contracts. AGL

     

                                       34
<PAGE>
 
    


reserves the right to allocate to the Contracts any federal, state or other tax
liability that may result in the future from maintenance of the Separate Account
or the Contracts.

Certain Series may elect to pass through to AGL any taxes withheld by foreign
taxing jurisdictions on foreign source income. Such an election will result in
additional taxable income and income tax to AGL. The amount of additional income
tax, however, may be more than offset by credits for the foreign taxes withheld
that the Series will also pass through. These credits may provide a benefit to
AGL.


                           DISTRIBUTION ARRANGEMENTS

Individuals who sell the Contracts will be licensed by state insurance
authorities as agents of AGL. The individuals will also be registered
representatives of (1) American General Securities Incorporated ("AGSI"), the
principal underwriter of the Contracts, (2) WM Fund Services, Inc. or (3) other
broker-dealer firms. However, some individuals may be representatives of firms
that are exempt from broker-dealer regulation. AGSI, WM Fund Services, Inc. and
any non-exempt broker-dealer firms are registered with the Securities and
Exchange Commission under the Securities Exchange Act of 1934 as broker-dealers
and are members of the National Association of Securities Dealers, Inc.

AGSI is a wholly-owned subsidiary of AGL. AGSI's principal business address is
2727 Allen Parkway, Houston, Texas 77019-2191.

AGL offers the Contracts on a continuous basis. AGSI and WM Fund Services, Inc.
have entered into certain revenue and cost-sharing arrangements in connection
with marketing the Contracts.

AGL compensates WM Fund Services, Inc. and other broker-dealers that sell the
Contracts according to one or more compensation schedules. The schedules provide
for a total payment of 7% of purchase payments that Owners make, which includes
commissions of up to 6.25%. AGL may also pay continuing "trail" commissions of
up to .50% of Owner Account Value.

AGL also has agreed to pay WM Fund Services, Inc. for its promotional
activities, such as solicitation of selling group agreements between broker-
dealers and AGL, agent appointments with AGL, printing and development of sales
literature to be used by AGL appointed agents and related marketing support, and
related special promotional campaigns. None of these distribution expenses
results in any additional charges under the Contracts that are not described
under "Charges under the Contracts."


                              SERVICES AGREEMENTS

American General Life Companies ("AGLC") is party to a general services
agreement with AGL. AGLC, an affiliate of AGL, is a corporation incorporated in
Delaware on November 24, 1997. Its address is 2727-A Allen Parkway, Houston,
Texas 77019-2191. Under this agreement, AGLC provides services to AGL, including
most of the administrative, data processing, systems, customer services, product
development, actuarial, auditing, accounting and legal services for AGL and the
Contracts.

We have entered into an arrangement with WM Advisors, Inc. to provide certain
services and discharge certain obligations. Under the arrangement, WM Advisors,
Inc. reimburses us on a monthly basis for certain administrative and Contract
and Contract Owner support expenses. The reimbursement is up to an annual rate
of 0.185% of the average daily net asset value of shares of the Portfolios and
Funds purchased by AGL at Contract Owners' instructions.


                                 LEGAL MATTERS

We are not involved in any legal matter about the Separate Account that would be
considered material to the interests of Owners. Steven A. Glover, Senior Counsel
of AGLC has passed upon the legality of the Contracts described in this
Prospectus. Freedman, Levy, Kroll & Simonds, Washington, D.C., has advised AGL
on certain federal securities law matters.

                           YEAR 2000 CONSIDERATIONS

Internal Systems.  AGL's ultimate parent, American General Corporation (AGC),
has numerous technology systems that are managed on a decentralized basis. AGC's
Year 2000 readiness efforts are being undertaken by its key business units with
centralized oversight. Each business unit, including AGL, has developed and is
implementing a plan to minimize the risk of a significant negative impact on its
operations.

While the specifics of the plans vary, the plans include the following
activities: (1) perform an inventory of our information technology and non-
information technology systems; (2) assess which items in the inventory may
expose us to business interruptions due to Year 2000 issues; (3) reprogram or
replace systems that are not Year 2000 ready; (4) test systems to prove that
they will function into the next century as they do currently; and (5) return
the systems to operations. As of December 31, 1998, substantially all of our
critical systems are Year 2000 ready and have been returned to operations.
However, activities (3) through (5) for certain systems are ongoing, with vendor
upgrades expected to be received during the first half of 1999.

Third Party Relationships.  We have relationships with various third parties who
must also be Year 2000 ready. These third parties provide (or receive) resources
and services to (or from) AGL and include organizations with which we exchange
information. Third parties include vendors of hardware, software, and
information services; providers of infrastructure services such as voice and
data communications and utilities for office facilities; investors; customers;
distribution channels; and joint venture partners. Third parties differ from
internal systems in that we exercise less, or no, control over Year 2000
readiness. We developed a plan to assess and attempt to reduce the risks
associated with the potential failure of third parties to achieve Year 2000
readiness. The plan includes the following activities: (1) identify and classify
third party dependencies; (2) research, analyze, and document Year 2000
readiness for critical third parties; and (3) test critical hardware and
software products and electronic interfaces. As of December 31, 1998, AGC has
identified and assessed approximately 700 critical third party dependencies,
including those relating to AGL. A more detailed evaluation will be completed
during first quarter 1999 as part of our contingency planning efforts. Due to
the various stages of third parties' Year 2000 readiness, our testing activities
will extend through 1999.

Contingency Plans.  AGL and its affiliates have commenced contingency planning
to reduce the risk of Year 2000-related business failures. The contingency
plans, which address both internal systems and third party relationships,
include the following activities: (1) evaluate the consequences of failure of
business processes with significant exposure to Year 2000 risk; (2) determine
the probability of a Year 2000-related failure for those processes that have a
high consequence of failure; (3) develop an action plan to complete contingency
plans for those processes that rank high in consequence and probability of
failure; and (4) complete the applicable action plans. We are currently
developing contingency plans and expect to substantially complete all
contingency planning activities during the second quarter of 1999.

Risks and Uncertainties.  Based on our plans to make internal systems ready for
Year 2000, to deal with third party relationships, and to develop contingency
actions, we believe that we will experience at most isolated and minor
disruptions of business processes following the turn of the century. Such
disruptions are not expected to have a material effect on AGL's future results
of operations, liquidity, or financial condition. However, due to the size and
complexity of this project, risks and uncertainties exist, and we cannot predict
a most reasonably likely worst case scenario. If conversion of our internal
systems is not completed on a timely basis (due to non-performance by
significant third-party vendors, lack of qualified personnel to perform the Year
2000 work, or other unforeseen circumstances in completing our plans), or if
critical third parties fail to achieve Year 2000 readiness on a timely basis,
the Year 2000 issues could have a material adverse impact on our operations
following the turn of the century.

Costs.  Through December 31, 1998, AGL has incurred, and anticipates that it
will continue to incur, costs for internal staff, third-party vendors, and other
expenses to achieve Year 2000 readiness. The cost of activities related to Year
2000 readiness has not had a material adverse effect on our results of
operations or financial condition. In addition, we have elected to accelerate
the planned replacement of certain systems as part of the Year 2000 plans. Costs
of the replacement systems are not passed to Divisions of the Separate Account.

THIS DISCLOSURE STATEMENT IS DESIGNED FOR OWNERS OF IRAS ISSUED BY AMERICAN
GENERAL LIFE INSURANCE COMPANY ON OR AFTER APRIL 30, 1999.

This Disclosure Statement is not part of your annuity contract but contains
general and standardized information which must be furnished to each person who
is issued an Individual Retirement Annuity. You must refer to your annuity
contract to determine your specific rights and obligations thereunder.

$2,000 or 100% of compensation and take a deduction for the entire amount
contributed. If you are a married individual filing a joint return, and your
compensation is less than your spouse's, the total deduction will, in general,
be the lesser of $4,000 or 100% of the combined earned income of both spouses,
reduced by any deduction for an IRA purchase payment allowed to your spouse. If
you are an active participant, but have an adjusted gross income (AGI) below a
certain level (see B. below), you may still make a deductible contribution. If,
however, you or your spouse is an active participant and your combined AGI is
above the specified level, the amount of the deductible contribution you may
make to an IRA will be phased down and eventually eliminated.

A. ACTIVE PARTICIPANT

You are an "active participant" for a year if you are covered by a retirement
plan. You are covered by a "retirement plan" for a year if your employer or
union has a retirement plan under which money is added to your account or you
are eligible to earn retirement credits. For example, if you are covered under a
profit-sharing plan, certain government plans, a salary reduction arrangement
(such as a tax sheltered annuity arrangement or a 401(k) plan), a Simplified
Employee Pension program (SEP), any Simple Retirement Account or a plan which
promises you a retirement benefit which is based upon the number of years of
service you have with the employer, you are likely to be an active participant.
Your Form W-2 for the year should indicate your participation status.

You are an active participant for a year even if you are not yet vested in your
retirement benefit. Also, if you make required contributions or voluntary
employee contributions to a retirement plan, you are an active participant. In
certain plans, you may be an active participant even if you were only with the
employer for part of the year.

     

                                     Page 1
<PAGE>
 
    


You are not considered an active participant if you are covered in a plan only
because of your service as 1) an Armed Forces Reservist for less than 90 days of
active service, or 2) a volunteer firefighter covered for firefighting service
by a government plan. Of course, if you are covered in any other plan, these
exceptions do not apply.

If you are married, (i) filed a separate tax return, and did not live with your
spouse at any time during the year, or (ii) filed a joint return and have a
joint AGI of less than $150,000, your spouse's active participation will not
affect your ability to make deductible contributions. If you are married and
file jointly, your deduction will be phased out between an AGI of $150,000 to
$160,000.

B. ADJUSTED GROSS INCOME (AGI)

If you are an active participant, you must look at your Adjusted Gross Income
for the year (if you and your spouse file a joint tax return, you use your
combined AGI) to determine whether you can make a deductible IRA contribution.
Your tax return will show you how to calculate your AGI for this purpose. If you
are at or below a certain AGI level, called the Threshold Level, you are treated
as if you were not an active participant and can make a deductible contribution
under the same rules as a person who is not an active participant.

If you are single, the Threshold Level is $30,000. If you are married and file a
joint tax return, the Threshold Level is $50,000. If you are married but file a
separate tax return, the Threshold Level will be $0.

For taxable years beginning in 1999, the Threshold Levels for single individuals
and for married individuals filing jointly will increase as follows:


                                                 THRESHOLD LEVEL
                                             ---------------------------
                                                           MARRIED
     FOR TAXABLE YEARS BEGINNING IN:         SINGLE     (FILING JOINTLY)
                                             -------    ----------------
     1999...............................     $31,000        $51,000
     2000...............................     $32,000        $52,000
     2001...............................     $33,000        $53,000
     2002...............................     $34,000        $54,000
     2003...............................     $40,000        $60,000
     2004...............................     $45,000        $65,000
     2005...............................     $50,000        $70,000
     2006...............................     $50,000        $75,000
     2007 and thereafter................     $50,000        $80,000

A married individual filing a joint tax return, who is not an active
participant, but whose spouse is, may, in any year, make deductible IRA
contributions equal to the lesser of $2,000 or 100% of the individual's earned
income. The Threshold Level for such individual is $150,000.

If your AGI is less than $10,000 above your Threshold Level, you will still be
able to make a deductible contribution, but it will be limited in amount. The
amount by which your AGI exceeds your Threshold Level

(AGI -- Threshold Level) is called your Excess AGI. The Maximum Allowable
Deduction is $2,000. In the case of a married individual filing jointly and
earning less than his or her spouse, the maximum Allowable Deduction is the
lesser of $2,000 or the spouse's income, less any deductible IRA contributions
or contributions to a Roth IRA. You can estimate your Deduction Limit as
follows:

(Your Deduction Limit may be slightly higher if you use this formula rather than
the table provided by the IRS.)


         $10,000 -- Excess AGI
         ---------------------
              $10,000          x Maximum Allowable Deduction = Deduction Limit

For the taxable year beginning in 2007, the deduction limit for married
individuals filing jointly will be determined as follows:


         $10,000 -- Excess AGI
         ---------------------
              $20,000          x Maximum Allowable Deduction = Deduction Limit

     

                                     Page 2
<PAGE>
 
    


You must round up the result to the next highest $10 level (the next highest
number which ends in zero). For example, if the result is $1,525, you must round
it up to $1,530. If the final result is below $200 but above zero, your
Deduction Limit is $200. Your Deduction Limit cannot, in any event, exceed 100%
of your compensation.

  EXAMPLE 1:  Ms. Smith, a single person, is an active participant and has an
  AGI of $36,619. In 1998, she would calculate her deductible IRA contribution
  as follows:

     Her AGI is $36,619
     Her Threshold Level is $30,000
     Her Excess AGI is (AGI - Threshold Level) or ($36,619 - $30,000) = $6,619
     Her Maximum Allowable Deduction is $2,000

     So, her IRA deduction limit is:


         $10,000 -- $6,619
         -----------------
              $10,000          x  $2,000 = $676 (rounded to $680)

  EXAMPLE 2:  Mr. and Mrs. Young file a joint tax return. Each spouse earns more
  than $2,000 and one is an active participant. Their 1999 combined AGI is
  $55,255. Neither spouse contributed to a Roth IRA. They may each contribute to
  an IRA and calculate their deductible contributions to each IRA as follows:

     Their AGI is $55,255
     Their Threshold Level is $51,000
     Their Excess AGI is (AGI - Threshold Level) or ($55,255 - $51,000) = $4,255
     The Maximum Allowable Deduction for each spouse is $2,000
     So, each spouse may compute his or her IRA deduction limit as follows:


         $10,000 -- $4,255
         -----------------
              $10,000          x  $2,000 = $1,149 (rounded to $1,150)

  EXAMPLE 3:  If, in Example 2, Mr. Young did not earn any compensation, each
  spouse could still contribute to an IRA and calculate their deductible
  contribution to each IRA as in Example 2.

  EXAMPLE 4:  In 1998, Mr. Jones, a married person, files a separate tax return
  and is an active participant. He has $1,500 of compensation and wishes to make
  a deductible contribution to an IRA.

     His AGI is $1,500
     His Threshold Level is $0
     His Excess AGI is (AGI - Threshold Level) or ($1,500 - $0) = $1,500
     His Maximum Allowable Deduction is $2,000
     So, his IRA deduction limit is:


         $10,000 -- $1,500
         -----------------
              $10,000          x  $2,000 = $1,700


  Even though his IRA deduction limit under the formula is $1,700, Mr. Jones may
  not deduct an amount in excess of his compensation, so, his actual deduction
  is limited to $1,500.


                     NON-DEDUCTIBLE CONTRIBUTIONS TO IRAs
                                        
Even if you are above the Threshold Level and thus may not make a deductible
contribution of up to $2,000 (or up to $4,000 in the case of married individuals
filing a joint return), you may still contribute up to the lesser of 100% of
compensation or $2,000 to an IRA ($4,000 in the case of married individuals
filing a joint return). The amount of your contribution which is not deductible
will be a non-deductible contribution to the IRA. You may also choose to make a
contribution non-deductible even if you could have deducted part or all of the
contribution. Interest or other earnings on your IRA contribution, whether from
deductible or non-deductible contributions, will not be taxed until taken out of
your IRA and distributed to you.

     

                                     Page 3
<PAGE>
 
    


If you make a non-deductible contribution to an IRA, you must report the amount
of the non-deductible contribution to the IRS on Form 8606 as a part of your tax
return for the year.

You may make a $2,000 contribution (or up to $4,000 in the case of married
individuals filing a joint return) at any time during the year, if your
compensation for the year will be at least $2,000 (or up to $4,000 in the case
of married individuals filing a joint return), without having to know how much
will be deductible. When you fill out your return, you may then figure out how
much is deductible.

You may withdraw an IRA contribution made for a year any time before April 15 of
the following year. If you do so, you must also withdraw the earnings
attributable to that portion and report the earnings as income for the year for
which the contribution was made. If some portion of your contribution is not
deductible, you may decide either to withdraw the non-deductible amount, or to
leave it in the IRA and designate that portion as a non-deductible contribution
on your tax return.

                               IRA DISTRIBUTIONS
                                        
Generally, IRA distributions which are not rolled over (see "Rollover IRA
Rules," below) are included in your gross income in the year they are received.
Non-deductible IRA contributions, however, are made using income which has
already been taxed (that is, they are not deductible contributions). Thus, the
portion of the IRA distributions consisting of non-deductible contributions will
not be taxed again when received by you. If you make any non-deductible IRA
contributions, each distribution from your IRA(s) will consist of a non-taxable
portion (return of deductible contributions, if any, and account earnings).

Thus, you may not take a distribution which is entirely tax-free. The following
formula is used to determine the non-taxable portion of your distributions for a
taxable year:

  Remaining
  Non-Deductible          x    Total             =          Nontaxable
  Contributions                Distributions                Distributions
  Year-End Total IRA           (for the year)               (for the year)
  Balances

To figure the year-end total IRA balance, you treat all of your IRAs as a single
IRA. This includes all regular IRAs (whether accounts or annuities), as well as
Simplified Employee Pension (SEP) IRAs, and Rollover IRAs. You also add back the
distributions taken during the year.

  EXAMPLE: An individual makes the following contributions to his or her IRA(s).

                                                                                   -------

       (before distributions in 1998)
</TABLE>

In 1998, the individual takes a distribution of $3,000. The total account
balance in the IRAs on 12/31/98 before 1998 distributions is $9,000. The non-
taxable portion of the distributions for 1998 is figured as follows:

<TABLE>
     <S>                                                        <C>        <C>    <C>        <C>    <C>
     Total non-deductible contributions                         $ 2,400    x      $ 3,000    =      $ 800
     Total account balance in the IRAs, before distributions    $ 9,000
</TABLE>

Thus, $800 of the $3,000 distribution in 1998 will not be included in the
individual's taxable income. The remaining $2,200 will be taxable for 1998.

                              ROLLOVER IRA RULES
                                        
1.  IRA TO IRA

You may withdraw, tax-free, all or part of the assets from an IRA and reinvest
them in one or more IRAs. The reinvestment must be completed within 60 days of
the withdrawal. No IRA deduction is allowed for the reinvestment. Amounts
required to be distributed because the individual has reached age 70 1/2 may not
be rolled over.

2.  EMPLOYER PLAN DISTRIBUTIONS TO IRA

All taxable distributions (known as "eligible rollover distributions") from
qualified pension, profit-sharing, stock bonus and tax sheltered annuity plans
may be rolled over to an IRA, with the exception of (1) annuities paid over a
life or life expectancy; (2) installments for a period of ten years or more; and
(3) required minimum distributions under Section 401(a)(9).

Rollovers may be accomplished in two ways. First, you may elect to have an
eligible rollover distribution paid directly to an IRA (a "direct rollover").
Second, you may receive the distribution directly and then, within 60 days of
receipt, roll the amount over to an IRA. Under the law, however, any amount that
you elect not to have distributed as a direct rollover will be subject to 20%
income tax withholding, and, if you are younger than age 59 1/2, may result in a
10% excise tax on any amount of the distribution that is included in income.
Questions regarding distribution options under the Act should be directed to
your Plan Trustee or Plan Administrator, or may be answered by consulting IRS
Regulations (S) 1.401(a)(31)-1, (S) 1.402(c)-2T and  31.3405(c)-1.

                     PENALTIES FOR PREMATURE DISTRIBUTIONS

If you receive a distribution from your IRA before you reach age 59 1/2, an
additional tax of 10 percent will be imposed under Code (S) 72(t), unless the
distribution (a) occurs because of your death or disability, (b) is for certain
medical care expenses or to an unemployed individual for health insurance
premiums, (c) is received as a part of a series of substantially equal payments
over your life or life expectancy, (d) is received as a part of a series of
substantially equal payments over the lives or life expectancy of you and your
beneficiary, or (e) the distribution is contributed to a rollover IRA, (f) is
used for a qualified first time home purchase for you, your spouse, children,
grandchildren, or ancestor, subject to a $10,000 lifetime maximum, or (g) is for
higher education purposes for you, your spouse, children or grandchildren.

                             MINIMUM DISTRIBUTIONS
                                        
Under the rules set forth in Code (S) 408(b)(3) and (S) 401(a)(9), you may not
leave the funds in your annuity contract indefinitely. Certain minimum
distributions are required. These required distributions may be taken in one of
two ways: (a) by withdrawing the balance of your annuity contract by a "required
beginning date," usually April 1 of the year following the date at which you
reach age 70 1/2; or (b) by withdrawing periodic distributions of the balance in
your annuity contract by the required beginning date. These periodic
distributions may be taken over (a) your life; (b) the lives of you and your
named beneficiary; (c) a period not extending beyond your life expectancy; or
(d) a period not extending beyond the joint life expectancy of you and your
named beneficiary.

If you do not satisfy the minimum distribution requirements, then, pursuant to
Code (S) 4974, you may have to pay a 50% excise tax on the amount not
distributed as required that year.

The foregoing minimum distribution rules are discussed in detail in IRS
Publication 590, "Individual Retirement Arrangements."

                                   REPORTING
                                        
You are required to report penalty taxes due on excess contributions, excess
accumulations, premature distributions, and prohibited transactions. Currently,
IRS Form 5329 is used to report such information to the Internal Revenue
Service.

                            PROHIBITED TRANSACTIONS
                                        
Neither you nor your beneficiary may engage in a prohibited transaction, as that
term is defined in Code (S) 4975.

Borrowing any money from this IRA would, under Code (S) 408(e)(3), cause the
annuity contract to cease to be an Individual Retirement Annuity and would
result in the value of the annuity being included in the owner's gross income in
the taxable year in which such loan is made.

Use of this annuity contract as security for a loan from the Company, if such
loan were otherwise permitted, would, under Code (S) 408(e)(4), cause the
portion so used to be treated as a taxable distribution.

                             EXCESS CONTRIBUTIONS
                                        
Tax Code (S) 4973 imposes a 6% excise tax as a penalty for an excess
contribution to an IRA. An excess contribution is the excess of the deductible
and nondeductible amounts contributed by the Owner to an IRA for that year over
the lesser of his or her taxable compensation or $2,000. (Different limits apply
in the case of a spousal IRA arrangement.) If the excess contribution is not
withdrawn by the due date of your tax return (including extensions) you will be
subject to the penalty.

                                 IRS APPROVAL

Your annuity contract and IRA endorsement have been approved by the Internal
Revenue Service as a tax qualified Individual Retirement Annuity. When received,
such approval by the Internal Revenue Service is a determination only as to the
form of the annuity and does not represent a determination of the merits of such
annuity.

This disclosure statement is intended to provide an overview of the applicable
tax laws relating to Individual Retirement Arrangements. It is not intended to
constitute a comprehensive explanation as to the tax consequences of your IRA.
AS WITH ALL SIGNIFICANT TRANSACTIONS SUCH AS THE ESTABLISHMENT OR MAINTENANCE
OF, OR WITHDRAWAL FROM AN IRA, APPROPRIATE TAX AND LEGAL COUNSEL SHOULD BE
CONSULTED. Further information may also be acquired by contacting your IRS
District Office or consulting IRS Publication 590.

                             FINANCIAL DISCLOSURE
            (WM STRATEGIC ASSET MANAGER, FORM NOS. 97010 AND 97011)
                                        
This Financial Disclosure is applicable to IRAs using a WM Strategic Asset
Manager Variable Annuity (contract form numbers 97010 and 97011) purchased from
American General Life Insurance Company on or after April 30, 1999. Earnings
under variable annuities are not guaranteed, and depend on the performance of
the investment option(s) selected. As such, earnings cannot be projected. Set
forth below are the charges associated with such annuities.

CHARGES:

(a)  Annual contract maintenance charge of $35 deducted at the end of each
     contract year (waived if cumulative contributions are $50,000 or more).

(b)  A maximum charge of $25 for each transfer, in excess of 12 free transfers
     annually, of contract value between divisions of the Separate Account.

     

                                     Page 6
<PAGE>
 
    


(c)  To compensate for mortality and expense risks assumed under the contract,
     variable divisions only will incur a daily charge at an annualized rate of
     1.25% of the average Separate Account Value of the contract during both the
     Accumulation and the Payout Phase.

(d)  Premium taxes, if applicable, may be charged against Accumulation Value at
     time of annuitization or upon the death of the Annuitant. If a jurisdiction
     imposes premium taxes at the time purchase payments are made, the Company
     may deduct a charge at that time, or defer the charge until the purchase
     payments are withdrawn, whether on account of a full or partial surrender,
     annuitization, or death of the Annuitant.

(e)  If the contract is surrendered, or if a withdrawal is made, there may be a
     Surrender Charge. The Surrender Charge equals the sum of the following:

        7% of purchase payments for surrenders and withdrawals made during the
        first contract year following receipt of the purchase payment
        surrendered;

        6% of purchase payments for surrenders and withdrawals made during the
        second contract year following receipt of the purchase payment
        surrendered;

        5% of purchase payments for surrenders and withdrawals made during the
        third contract year following receipt of the purchase payment
        surrendered;

        5% of purchase payments for surrenders and withdrawals made during the
        fourth contract year following receipt of the purchase payment
        surrendered;

        4% of purchase payments for surrenders and withdrawals made during the

        surrendered;

        2% of purchase payments for surrenders and withdrawals made during the
        seventh contract year following receipt of the purchase payment
        surrendered.

  There will be no charge imposed for surrenders and withdrawals made during the
  eighth and subsequent contract years following receipt of the purchase
  payments surrendered.

  Under certain circumstances described in the contract, portions of a partial

     at an annualized rate of .15% of the average Separate Account Value of the
     contract during the Accumulation and the Payout Phase.

(g)  Each variable division will be charged a fee for asset management and other
     expenses deducted directly from the underlying fund during the Accumulation
     and Payout Phase. Total fees will range between 0.35% and 1.50%.

         ROTH INDIVIDUAL RETIREMENT ANNUITY (IRA) DISCLOSURE STATEMENT

                                 INTRODUCTION

THIS DISCLOSURE STATEMENT IS DESIGNED FOR OWNERS OF ROTH IRAS ISSUED BY AMERICAN
GENERAL LIFE INSURANCE COMPANY ON AND AFTER APRIL 30, 1999.

This Disclosure Statement is not part of your contract but contains general and
standardized information which must be furnished to each person who is issued a
Roth IRA. You must refer to your contract to determine your specific rights and
obligations thereunder.

Revocation.  If you are purchasing a new or rollover Roth IRA, then if for any
reason you, as a recipient of this Disclosure Statement, decide within 10 days
from the date your contract is delivered that you do not desire to retain your
Roth IRA, written notification to the Company must be mailed, together with your
contract, within that period. If such notice is mailed within 10 days, current
contract value or contributions if required, without adjustments for any
applicable sales commissions or administrative expenses, will be refunded.

MAIL NOTIFICATION OF REVOCATION AND YOUR CONTRACT TO:

   American General Life Insurance Company
   Annuity Administration Department
   P. O. Box 1401
   Houston, Texas 77251-1401
   Phone No. (800) 277-0914 and (713) 831-3505.

Deductibility.  Contributions to your Roth IRA are not deductible on your
personal income tax return. Your Roth IRA contributions are made with money that
has already been taxed.

Eligibility.  You can contribute up to the amount of your earned income, but not
more than $2,000 in any one year, even if you are age 70 1/2 or older. In
addition, non-working spouses can contribute to a Roth IRA, provided the working
spouse has at least as much earned income as both spouses will contribute to
their respective Roth IRAs.

Contribution Limits.  Contributions to your Roth IRA are subject to the
limitations described in sections 408A and 219 of the Internal Revenue Code of
1986, as amended (the "Code"). In general, you may contribute up to $2,000 per
year to your Roth IRA. However, contributions to your Roth IRA must be
aggregated with contributions to traditional deductible or non-deductible IRAs
for purposes of the annual $2,000 limit. In addition, your contribution limit
may be lower than $2,000 if your adjusted gross income (AGI) exceeds a certain
amount. For married individuals filing a joint return with AGI between $150,000
and $160,000, single individuals with AGI between $95,000 and $110,000 and
married individuals filing separately with an AGI between $0 and $10,000, the
$2,000 annual contribution limit is gradually phased out. These limits apply
without regard to whether either spouse is an active participant, as that term
is defined in Code section 219.

Applying the Contribution Limits.  If your AGI exceeds the contribution limits
described above, then you may determine the extent to which your contribution is
phased out by using the following formula:

  (1)  Start with your AGI.

  (2)  Subtract from the amount in (1):

       a)  $150,000 if filing a joint return

       b)  $0 if married filing a separate return

       c)  $95,000 if single, head of household or married filing a separate
           return and you lived apart from your spouse during the entire year.

  (3) Divide the result in (2) by $15,000 ($10,000 if filing a joint return).
     

                                   Page 1-R

<PAGE>
 
    
  (4) Multiply your contribution limit (after reduction for any contributions to
      traditional IRAs) by the result in (3).

  (5) Subtract the result in (4) from your contribution limit before this
      reduction. The result is your reduced contribution limit.

You may round your reduced contribution limit up to the nearest $10. If your
reduced contribution limit is more than $0, but less than $200, increase the
limit to $200.

  Example.  You are a single individual with taxable compensation of $113,000.
  You want to make the maximum allowable contribution to your Roth IRA for 1998.
  Your AGI for 1998 is $100,000. You have not contributed to any traditional
  IRA, so your contribution limit before the AGI reduction is $2,000. Your
  reduced Roth IRA contribution is $1,350, figured as follows:
 
  (1) Modified AGI = $100,000
 
  (2) $100,000 -- $95,000 = $5,000
 
  (3) $  5,000 (divided by) $15,000 = .3333

  (4) $2,000 (contribution limit before adjustment) x .3333 = $667

  (5) $2,000 -- $667 = $1,333. This figure is reduced up to the nearest $10, so
      your reduced Roth IRA contribution limit is $1,340.

Conversions or rollovers.  Conversions or rollovers from a traditional IRA are
only permitted for taxpayers whose AGI does not exceed $100,000 in the year of
the conversion or rollover. Neither conversions nor rollovers are permitted for
married individuals filing separate returns. Conversions or rollovers from
traditional IRAs to Roth IRAs are generally taxed entirely in the year of the
conversion or rollover. However, a special rule applies to conversions or
rollovers from traditional IRAs to Roth IRAs during 1998. In these cases, you
can elect instead to be taxed proportionately over the four-year period from
1998 through 2001. Conversions or rollovers to your Roth IRA are permitted only
from a traditional IRA or another Roth IRA. You may not convert or roll over
directly to a Roth IRA from a qualified plan described in section 401(a) or
401(k) of the Code, or from an annuity described in section 403(b) of the Code.

Taxation of Distributions.  Distributions from your Roth IRA will be treated
first as withdrawals of your regular contributions, then withdrawals of
conversion or rollover contributions, then finally any earnings. Therefore,
distributions will be non-taxable to the extent of your investment in your Roth
IRA. However, a distribution from your Roth IRA may be subject to a 10% penalty
tax, even if the distribution is not otherwise taxable, if it is a distribution
of a conversion or rollover amount within five years of the conversion or
rollover. Your Roth IRA is not subject to the minimum distribution rules before
death or to the incidental benefit rules, both of which are contained in section
401(a)(9).

Distributions from your Roth IRA which consist of earnings will be taxable
unless they are:

1. Made at least five years after you established your first Roth IRA (whether
   the Roth IRA was established with regular contributions or conversion or
   rollover contributions); and

2. Made after you attain age 59 1/2, or for qualifying first-time homebuyer
   expenses (in accordance with section 72(t)(2)(F), or on account of your death
   or disability (as defined in section 72(m)(7)).

Taxable distributions may also be subject to a 10% penalty tax unless you are
over age 59 1/2 or you meet one of several other exceptions to the penalty tax.
In general, the same exceptions to the 10% penalty tax that apply to traditional
IRAs also apply to Roth IRAs. See IRS publication 590 for a discussion of the
exceptions to the penalty tax.

Post-death distributions.  Upon your death, distributions from your Roth IRA to
your beneficiary generally must commence by the end of the next calendar year
and be paid over a period no longer than your beneficiary's life expectancy.
Alternatively, your beneficiary can take a complete distribution of the balance
of your Roth IRA account by the end of the fifth calendar year after your death.

Reporting.  You are required to report penalty taxes due on excess
contributions, excess accumulations, premature distributions, and prohibited
transactions. Currently, IRS Form 5329 is used to report such information to the
Internal Revenue Service.

Excess contributions.  You may be subject to a 6% tax on excess contributions if
(1) contributions to your other individual retirement arrangements have been
made in the same tax year, (2) your adjusted gross income exceeds the applicable
limits in Article II of the endorsement for the tax year, or (3) you and your
spouse's compensation does not exceed the amount contributed for both of you for
the tax year.

IRS Approval.  This disclosure statement is intended to provide a general
overview of the applicable tax laws relating to Roth Individual Retirement
Annuities. It is not intended to constitute a comprehensive explanation as to
the tax consequences of your Roth IRA. AS WITH ALL SIGNIFICANT TRANSACTIONS SUCH
AS THE ESTABLISHMENT OR MAINTENANCE OF, OR WITHDRAWAL FROM A ROTH IRA,
APPROPRIATE TAX AND LEGAL COUNSEL SHOULD BE CONSULTED. Further information may
also be acquired by contacting your IRS District Office or consulting IRS
Publication 590.

                              FINANCIAL DISCLOSURE
                                        
    WM Strategic Asset Manager Variable Annuity (Form Nos. 97010 and 97011 )
                                        
This Financial Disclosure is applicable to Roth IRAs using a WM Strategic Asset
Manager Variable Annuity (contract form numbers 97010 or 97011) purchased from
American General Life Insurance Company on and after April 30, 1999.

Earnings under variable annuities are not guaranteed, and depend on the
performance of the investment option(s) selected. As such, earnings cannot be
projected. Set forth below are the charges associated with such annuities.

CHARGES:

(a) Annual contract maintenance charges of $35 deducted at the end of each
  contract year (waived if cumulative contributions are $50,000 or more).

(b) A maximum charge of $25 for each transfer, in excess of 12 free transfers
    annually, of contract value between divisions of the Separate Account.

(c) To compensate for mortality and expense risks assumed under the contract,
    variable divisions only will incur a daily charge at an annualized rate of
    1.25% of the average Separate Account Value of the contract during both the
    Accumulation and the Payout Phase.

(d) Premium taxes, if applicable, may be charged against Accumulation Value at
    time of annuitization or upon the death of the Annuitant. If a jurisdiction
    imposes premium taxes at the time purchase payments are made, the Company
    may deduct a charge at that time, or defer the charge until the purchase
    payments are withdrawn, whether on account of a full or partial surrender,
    annuitization, or death of the Annuitant.

(e) If the contract is surrendered, or if a withdrawal is made, there may be a
    Surrender Charge. The Surrender Charge equals the sum of the following:

  7% of purchase payments for surrenders and withdrawals made during the first
  contract year following receipt of the purchase payments surrendered;

  6% of purchase payments for surrenders and withdrawals made during the second
  contract year following receipt of the purchase payments surrendered;

  5% of purchase payments for surrenders and withdrawals made during the third
  contract year following receipt of the purchase payments surrendered;

  5% of purchase payments for surrenders and withdrawals made during the fourth
  contract year following receipt of the purchase payments surrendered;
     

                                   Page 3-R

  4% of purchase payments for surrenders and withdrawals made during the fifth
  contract year following receipt of the purchase payments surrendered;

  3% of purchase payments for surrenders and withdrawals made during the sixth
  contract year following receipt of the purchase payments surrendered;

  2% of purchase payments for surrenders and withdrawals made during the seventh
  contract year following receipt of the purchase payments surrendered.

There will be no charge imposed for surrenders and withdrawals made during the
eighth and subsequent contract years following receipt of the purchase payments
surrendered.

Under certain circumstances described in the contract, portions of a partial
withdrawal may be exempt from the Surrender Charge.

(f) To compensate for administrative expenses, a daily charge will be incurred
    at an annualized rate of .15% of the average Separate Account Value of the
    contract during the Accumulation and the Payout Phase.

(g) Each variable Division will be charged a fee for asset management and other
    expenses deducted directly from the underlying fund during the Accumulation
    and Payout Phase. Total fees will range between 0.35% and 1.50%, depending
    on the Division.

                              GENERAL INFORMATION

AGL (formerly American General Life Insurance Company of Delaware) is a
successor in interest to a company previously organized as a Delaware
corporation in 1917.  AGL redomesticated as a Texas insurer effective December
31, 1991 and changed its name to American General Life Insurance Company.  AGL
is a wholly-owned subsidiary of AGC Life Insurance Company, a Missouri
corporation ("AG Missouri"). It is engaged primarily in the life insurance
business and annuity business.  AG Missouri, in turn, is a wholly-owned
subsidiary of American General Corporation, a Texas holding corporation engaged
primarily in the insurance business.


                            REGULATION AND RESERVES

AGL is subject to regulation and supervision by the insurance departments of the
states where it is licensed to do business. This regulation covers a variety of
areas, including:

   .  benefit reserve requirements,

   .  adequacy of insurance company capital and surplus,

   .  various operational standards, and

   .  accounting and financial reporting procedures.

AGL's operations and accounts are subject to periodic examination by insurance
regulatory authorities.

Under most insurance guaranty fund laws, a state can assess insurers doing
business in the state for covered insurance contract losses incurred by
insolvent companies.  State laws set limits for these assessments. However, AGL
cannot reasonably estimate the amount of any future assessments of AGL under
these laws. Most states have the authority to excuse or defer an assessment, if
it would threaten an insurer's own financial strength.  The Account Value held
in the Separate Account may not be 
     

                                       2
<PAGE>
 
    

covered by insurance guaranty fund laws. The Account Value held in the Fixed
Account is covered by the insurance guaranty fund laws.


The federal government generally has not directly regulated the business of
insurance.  However, federal initiatives often have an impact on the business in
a variety of ways.  Federal measures that may adversely affect the insurance
business include:

   .  employee benefit regulation,

   .  tax law changes affecting the taxation of insurance companies or of
      insurance products,

   .  changes in the relative desirability of various personal investment
      vehicles, and

   .  removal of impediments on the entry of banking institutions into the
      business of insurance.

Also, both the executive and legislative branches of the federal government are
considering various insurance regulatory matters.  This could ultimately result
in direct federal regulation of some aspects of the insurance business.  AGL
cannot predict whether this will occur or, if it does, what the effect on AGL
would be.

State insurance law requires AGL to carry reserves on its books, as liabilities,
to meet its obligations under outstanding insurance contracts.  AGL bases these
reserves on assumptions about future claims experience and investment returns,
among other things.

Neither the reserve requirements nor the other aspects of state insurance
regulation provide absolute protection to holders of insurance contracts,
including the Contracts, if AGL were to incur claims or expenses at rates
significantly higher than expected.  This might happen, for example, due to a
spread of acquired immune deficiency syndrome or other infectious diseases or
catastrophes, or significant unexpected losses on its investments.


                             INDEPENDENT AUDITORS

The 1998 consolidated financial statements of AGL and the financial statements
of the WM Strategic Asset Manager Divisions of Separate Account D included in
this Statement were audited by Ernst & Young LLP, independent auditors, as set
forth in their reports.  We include these financial statements in this Statement
in reliance upon the reports of Ernst & Young LLP that appear later on in this
Statement.  Ernst & Young LLP gives their reports upon their authority as
experts in accounting and auditing.  Ernst & Young LLP is located at One Houston
Center, 1221 McKinney, Suite 2400, Houston, TX  77010-2007.


                                   SERVICES

AGL and American General Life Companies ("AGLC") are parties to a services
agreement.  Most of the affiliated companies within the American General
Corporation holding company system, including certain life insurance companies,
are also parties to the agreement.  AGLC is a corporation 
     

                                       3
<PAGE>
 
    

incorporated in Delaware on November 24, 1997, with its home office located at
2727-A Allen Parkway, Houston, Texas 77019. AGLC provides shared services to AGL
and certain other life insurance companies at cost. These services include data
processing, systems, customer services, product development, actuarial,
auditing, accounting, and legal. AGL did not pay any fees to AGLC in 1997,
because AGLC performed no services under the agreement. AGL paid AGLC
$70,431,229 in 1998.


                             PRINCIPAL UNDERWRITER

American General Securities Incorporated ("AGSI") is the principal underwriter
for the Contracts.  AGSI also serves as principal underwriter to AGL's Separate
Account A and Separate Account VL-R, and to Separate Account E of American
General Life Insurance Company of New York. All of these other separate accounts
are unit investment trusts registered under the Investment Company Act of 1940.
AGSI, a Texas corporation, is a wholly-owned subsidiary of AGL and a member of
the National Association of Securities Dealers, Inc.

As principal underwriter for the Separate Account, AGSI has not received any
compensation for any of the past three years.

AGL offers the securities under the Contracts on a continuous basis.


                               ANNUITY PAYMENTS

GENDER OF ANNUITANT

When annuity payments are based on life expectancy,  the amount of each annuity
payment ordinarily will be higher if the Annuitant or other measuring life is a
male, as compared with a female, under an otherwise identical Contract. This is
because, statistically, females tend to have longer life expectancies than
males.

However, Montana, and certain other jurisdictions, do not permit differences in
annuity payment rates between males and females.

In addition, employers should be aware that, under most employer-sponsored
plans, the law prohibits Contracts that make distinctions based on gender. Under
these plans, AGL will make available Contracts with no such differences.

MISSTATEMENT OF AGE OR GENDER AND OTHER ERRORS

If the age or gender of an Annuitant has been misstated to us, any amount
payable will be the amount that the purchase payments paid would have purchased
at the correct age and gender.  If we made any overpayments because of incorrect
information about age or  gender or any error or miscalculation, we will deduct
the overpayment from the next payment or payments due.  We will add any
underpayments to the next payment.  We will credit or charge the amount of any
adjustment with interest at the assumed interest rate used in the Contract's
annuity tables.

               CHANGE OF INVESTMENT ADVISER OR INVESTMENT POLICY

Unless otherwise permitted by law or regulation, no Series may change the
investment adviser to any Series or any investment policy without the consent of
the shareholders.  If required, we will file approval of or change of any
investment objective with the insurance department of each state where a
Contract has been delivered.  We will notify you (or, after annuity payments
start, the payee) of any material investment policy change that we have
approved.  We will also notify you of any investment policy change before its
implementation by the Separate Account, if the change requires your comment or
vote.


                      PERFORMANCE DATA FOR THE DIVISIONS

We may quote investment results for the available Divisions of Separate Account
D from time to time. These results will not be an estimate or guarantee of
future investment performance.  Nor will they represent the actual experience of
amounts invested by a particular Owner.  We will carry performance figures to
the nearest one-hundredth of one percent.  We may include in the figures the
effect of voluntary fee waivers and expense reimbursements to the Funds from
their investment adviser and administrator.

AVERAGE ANNUAL TOTAL RETURN CALCULATIONS

Each Division may advertise its average annual total return.  We calculate each
Division's average annual total return quotation under the following standard
method that the SEC prescribes:

   .  We take a hypothetical $1,000 investment in the Division's Accumulation
      Units on the first day of the period at the maximum offering price. This
      figure is the Accumulation Unit Value per unit ("initial investment").

   .  We calculate the ending redeemable value ("redeemable value") of that
      investment at the end of the period. The redeemable value reflects the
      effect of (1) any applicable Surrender Charge at the end of the period and
      (2) all other recurring charges and fees applicable under the Contract to
      all Owner accounts. Other charges and fees include the Mortality and
      Expense Risk Charge, the Administrative Expense Charge, and the Annual
      Contract Fee. We do not reflect any premium taxes in the calculation.

   .  We divide the redeemable value by the initial investment.

   .  We take this quotient to the Nth root (N representing the number of years
      in the period), subtract 1 from the result, and express the result as a
      percentage.

/1/ One year return quotations show only for those Divisions which commenced
    operations before January 1, 1998.

/2/ The dates when the Divisions commenced operations are as follows: Strategic
    Growth and Conservative Growth Portfolio Divisions, June 2, 1997; Balanced
    Portfolio Division, September 2, 1997; Flexible Income Portfolio Division,
    September 8, 1997; Income Portfolio Division, April 22, 1998; Money Market
    Fund Division, July 16, 1997; Growth & Income, Northwest and Growth Fund
    Division, April 29, 1998; Bond & Stock Fund Division, April 30, 1998; Short
    Term High Quality Bond Fund Divisions, May 22, 1998; Emerging Growth and
    International Growth Fund Divisions, June 3, 1998; U.S. Government
    Securities Fund Division, June 10, 1998; Income Fund Division, June 24,
    1998.

/3/ The Income Portfolio Division originally commenced operations on October 22,
    1997. The Division suspended operations during the period of November 4,
    1997 through April 21, 1998. We use April 22, 1998 as the commencement of
    operations date for the Division.

TOTAL RETURN CALCULATIONS (WITHOUT SURRENDER CHARGE OR ANNUAL CONTRACT FEE)

Each Division may also advertise non-standardized total return.  We calculate
non-standardized total return in the same manner and for the same time periods
as standardized average annual total return, which we describe immediately
above.  However, in making the redeemable value calculation, we do not deduct
any applicable Surrender Charge that we may impose at the end of the period.
This is because we assume that the Certificate will continue through the end of
each period.  We also do not deduct the Annual Contract Fee.  Deducting these
charges would reduce the resulting performance results.

CUMULATIVE TOTAL RETURN CALCULATIONS (WITHOUT SURRENDER CHARGE OR ANNUAL
CONTRACT FEE)

Each Division may also advertise non-standardized cumulative total return
performance.  Cumulative total return performance is the compound rate of return
on a hypothetical initial investment of $1,000 in each Division's Accumulation
Units on the first day of the period at the maximum offering price.  This figure
is the Accumulation Unit value per unit ("initial investment").  Cumulative
total return

figures (and the related "Growth of a $1,000 Investment" figures set forth
below) do not include the effect of any premium taxes, any applicable Surrender
Charge, or the Annual Contract Fee. Cumulative total return quotations reflect
changes in Accumulation Unit value. We calculate these quotations by finding the
cumulative rates of return of the hypothetical initial investment over various
periods, according to the following formula, and then expressing those rates as
a percentage:

                                C = (ERV/P) - 1
Where:

C =     cumulative total return

P =     a hypothetical initial investment of $1,000

ERV =   ending redeemable value at the end of the applicable period of a
        hypothetical $1,000 investment made at the beginning of the applicable
        period.

HYPOTHETICAL PERFORMANCE

Each Division may advertise hypothetical performance, based on the calculations
described above, where all or a portion of the actual historical performance of
the corresponding Series in which the Division invests pre-dates the effective
date of the Division.

The tables below provide hypothetical performance information for the available
Divisions of the Separate Account  based on the actual historical performance of
the corresponding Series in which each of these Divisions invests.  This
information reflects all actual charges and deductions of these Series and the
Separate Account that hypothetically would have been made if the Separate
Account invested assets under the Contracts in these Series for the periods
indicated.

YIELD CALCULATIONS

We calculate the yields for the U.S. Government Securities Fund, Short-Term High
Quality Bond Fund, and Income Fund Divisions by a standard method that the SEC
prescribes.  The hypothetical yields for the U.S. Government Securities Fund,
Short-Term High Quality Bond Fund, and Income Fund Divisions, based upon the one
month period ended December 31, 1998, were 7.06%, 5.66% and 8.17%, respectively.
We calculate the yield quotation by dividing

   .  the net investment income per Accumulation Unit earned during the
      specified one month or 30-day period by the Accumulation Unit values on
      the last day of the period, according to the following formula that
      assumes a semi-annual reinvestment of income:

                         YIELD = 2[((a-b)/cd + 1)6  1]

a = net dividends and interest earned during the period by the Series
    attributable to the Division

b = expenses accrued for the period (net of reimbursements)

c = the average daily number of Accumulation Units outstanding during the period

d = the Accumulation Unit value per unit on the last day of the period
     

                                       9
<PAGE>
 
    

The yield of each Division reflects the deduction of all recurring fees and
charges that apply to each Division.  These fees and charges include the
Mortality and Expense Risk Charge and the Administrative Expense Charge.  They
do not reflect the deduction of Surrender Charges or premium taxes.

MONEY MARKET FUND DIVISION YIELD AND EFFECTIVE YIELD CALCULATIONS

We calculate the Money Market Fund Division's yield by a standard method that
the SEC prescribes.  Under that method, we base the current yield quotation on a
seven day period and calculate that yield as follows:

   .  We take the net change in the Accumulation Unit value during the period.

   .  We divide that net change by the Accumulation Unit value at the beginning
      of the period to obtain the base period return.

   .  We multiply the base period return by the fraction 365/7 to obtain the
      current yield figure.

   .  We carry the current yield figure to the nearest one-hundredth of one
      percent.

We do not include realized capital gains or losses and unrealized appreciation
or depreciation of the Division's Portfolio in the calculation.  The Money
Market Fund Division's hypothetical historical yield for the seven day period
ended December 31, 1998, was  3.26%.

We determine the Money Market Fund Division's effective yield by taking the base
period return (computed as described above) and calculating the effect of
assumed compounding.  The formula for the effective yield is: (base period
return +1)/365/7/-1.  The Money Market Fund Division's hypothetical historical
effective yield for the seven day period ended December 31, 1998, was 3.31%.

Yield and effective yield do not reflect the deduction of Surrender Charges or
premium taxes that we may impose when you redeem Accumulation Units.

PERFORMANCE COMPARISONS

In our advertising and sales literature, we may compare the performance of each
or all of the available Divisions of the Separate Account to the performance of
(1) other variable annuities in general or (2) particular types of variable
annuities that invest in mutual funds, or series of mutual funds, with
investment objectives similar to each of the Divisions of the Separate Account.

Lipper Analytical Services, Inc. ("Lipper") and the Variable Annuity Research
and Data Service ("VARDS(R)") are independent services that monitor and rank the
performance of variable annuity issuers in each of the major categories of
investment objectives on an industry-wide basis.  Lipper's rankings include
variable life insurance issuers as well as variable annuity issuers.  VARDS(R)
rankings compare only variable annuity issuers.  The performance analyses
prepared by Lipper and VARDS(R) rank such issuers on the basis of total return.
Total return assumes the reinvestment of dividends and distributions, but does
not take into consideration sales charges, redemption fees or certain expense
     

                                       10

deductions at the separate account level.  In addition, VARDS(R) prepares risk-
adjusted rankings, which consider the effects of market risk on total return
performance.

In addition, we may compare each Division's performance in advertisements and
sales literature to the following benchmarks:

   .  the Standard & Poor's 500 Composite Stock Price Index, an unmanaged
      weighted index of 500 leading domestic companies that represents
      approximately 80% of the market capitalization of the United States equity
      market;

   .  the Dow Jones Industrial Average, an unmanaged unweighted average of 30
      blue chip industrial corporations listed on the New York Stock Exchange
      and generally considered representative of the United States stock market;

   .  the Consumer Price Index, published by the U.S. Bureau of Labor
      Statistics, a statistical measure of change, over time, in the prices of
      goods and services in major spending groups and generally is considered to
      be a measure of inflation;

   .  the Lehman Brothers Government and Domestic Strategic Income Index, the
      Salomon Brothers High Grade Domestic Strategic Income Index, and the
      Merrill Lynch Government/Corporate Master Index, unmanaged indices that
      are generally considered to represent the performance of intermediate and
      long term bonds during various market cycles; and

   .  the Morgan Stanley Dean Witter Capital International Europe Australasia 
      Far East Index, an unmanaged index that is considered to be generally
      representative of major non-United States stock markets.

                      EFFECT OF TAX-DEFERRED ACCUMULATION

The Contracts qualify for tax-deferred treatment on earnings.  This tax-deferred
treatment increases the amount available for accumulation by deferring taxes on
any earnings until the earnings are withdrawn. The longer the taxes are
deferred, the more the potential you have for the assets under your Contract to
grow over the term of the Contracts.

The hypothetical tables set out below illustrate this potential.  The tables
compare accumulations based on a single initial purchase payment of $100,000
compounded annually under:

   .  a Contract, whose earnings are not taxed until withdrawn in connection
      with a full surrender, partial withdrawal, or annuitization, or
      termination due to insufficient Account Value ("withdrawal of earnings"),
      and

   .  an investment whose earnings are taxed on a current basis ("Taxable
      Investment"), based on an assumed tax rate of 28%, and the assumed earning
      rates specified.

                            (7.50% earnings rate)
Contract                     $143,563   $206,103   $424,785
Contract (after Taxes)       $131,365   $176,394   $333,845
Taxable Investment           $130,078   $169,202   $286,294
 
                           (10.00% earnings rate)
Contract                     $161,051   $259,374   $672,750
Contract (after Taxes)       $143,957   $214,749   $512,380
Taxable Investment           $141,571   $200,423   $401,694
 
The hypothetical tables do not reflect any fees or charges under a Contract or
Taxable Investment.  However, the Contracts impose:

   .  a Mortality and Expense Risk Charge of 1.25%,

   .  a Surrender Charge (applicable to withdrawal of earnings for the first
      seven Contract years) up to a maximum of 7%,

   .  an Administrative Expense Charge of 0.15%, and

   .  an Annual Contract Fee of $35.

A Taxable Investment could incur comparable fees or charges.  Fees and charges
would reduce the return from a Contract or Taxable Investment.

Under the Contracts, a withdrawal of earnings is subject to tax, and may be
subject to an additional 10% tax penalty before age 59 1/2.

These tables are only illustrations of the effect of tax-deferred accumulations
and are not a guarantee of future performance.

                             FINANCIAL STATEMENTS

Separate Account D has a total of  69 Divisions as of the date of this
Statement.  Fifteen Divisions (the "WM Strategic Asset Manager Divisions") are
available under the Contracts that are the subject of this Statement.  The
December 31, 1998 financial statements for the WM Strategic Asset Manager
Divisions which are included in this statement relate only to these 15
Divisions.  Forty-three of the remaining  54 Divisions had operations as of
December 31, 1998.  The remaining 11 Divisions of Separate Account D had no
operations as of December 31, 1998.

You should consider the financial statements of AGL that we include in this
Statement primarily as bearing on the ability of AGL to meet its obligations
under the Contracts.

Board of Directors
American General Life Insurance Company
 and
Contract Owners
American General Life Insurance Company
 WM Strategic Asset Manager Divisions
 of Separate Account D

We have audited the accompanying statement of net assets of  the WM Strategic
Asset Manager Divisions (formerly the "Sierra Asset Manager Divisions") of
American General Life Insurance Company (the "Company") Separate Account D as of
December 31, 1998, the related statement of operations for the year then ended,
and the statement of changes in net assets for each of the two years in the
period then ended. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of December 31, 1998, by correspondence with
the transfer agents. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the WM Strategic Asset Manager
Divisions of American General Life Insurance Company Separate Account D at
December 31, 1998, the results of its operations for the year then ended, and
the changes in its net assets for each of the two years in the period then
ended, in conformity with generally accepted accounting principles.

Note A - Organization

  The WM Strategic Asset Manager (formerly, "Sierra Asset Manager") Divisions
(the "Divisions") of American General Life Insurance Company Separate Account D
(the "Separate Account") received their first deposits in June, 1997.  The
Separate Account was established by resolution of the Board of Directors of
American General Life Insurance Company (the "Company")  on  November 19, 1973.
The Separate Account is registered under the Investment Company Act of 1940 as a
unit investment trust and consists of fifty-eight Divisions.  During April 1998,
nine additional Divisions became available to WM Strategic Asset Manager
contract owners, and the Income Portfolio re-commenced operations.  The fifteen
Divisions available from the WM Variable Trust (formerly, "Sierra Variable
Trust")  to WM Strategic Asset Manager contract owners are as follows:

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION

  The accompanying financial statements of the Divisions of the Separate Account
have been prepared on the basis of generally accepted accounting principles
("GAAP").  The accounting principles followed by the Divisions and the methods
of applying those principles are presented below or in the footnotes which
follow.

  SECURITY VALUATION - The investments in shares of  the WM Variable Trust
mutual funds are valued at the closing net asset value (market) per share as
determined by the fund on the day of measurement.

  SECURITY TRANSACTIONS AND RELATED INVESTMENT INCOME - Security transactions
are accounted for on the date the order to buy or sell is executed (trade date).
Dividend income and distributions of capital gains are recorded on the ex-
dividend date and reinvested upon receipt.  Realized gains and losses from
security transactions are determined on the basis of identified cost.

  ADMINISTRATIVE EXPENSES AND MORTALITY AND EXPENSE RISK CHARGES - Deductions
for administrative expenses and mortality and expense risks assumed by the
Company are calculated daily,  at an annual rate, on the daily net asset value
of the Divisions and are paid to the Company.  The annual rate for the
administrative expense charge is 0.15% and the annual rate for the mortality and
expense risk charge is 1.25%.  A surrender charge is applicable to certain
withdrawal amounts pursuant to the contract and is payable to the Company.  An
annual contract fee of $35 is charged on contracts having cumulative premiums of
less than $50,000.  This fee is not imposed during the Annuity period.  The
total surrender charges and contract fees collected for the period ended
December 31, 1998 were $18,774 and $1,540, respectively.

  For investment advisory services, monthly fees are paid to WM Advisors, Inc.
and WM Shareholder Services, Inc. by each portfolio and underlying fund,
respectively, based upon a percentage of the average net assets of such
portfolio or underlying fund.  While the management fee is a significant
component of each fund's annual operating costs, each fund pays other expenses,
such as legal and audit fees.   For its services as administrator, WM
Shareholder Services, Inc. is also paid a monthly fee by each portfolio and
underlying fund, respectively, based upon a percentage of the average net assets
of such portfolio or underlying Fund.  WM Advisors, Inc. and WM Shareholders
Services, Inc. may, from time to time, agree to reimburse the funds for
management fees and other expenses above a certain limit.

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION -
CONTINUED

  ANNUITY RESERVES - Annuity reserves are computed for currently payable
contracts according to the 1983a Individual Annuity Mortality Table projected
under Scale G factors.  The assumed interest rate is 3.5 percent.  Charges to
annuity reserves for mortality and expense risk experience are reimbursed to the
Company if the reserves required are less than originally estimated.  If
additional reserves are required, the Company reimburses the Separate Account.

NOTE C - FEDERAL INCOME TAXES

  The Company is taxed as a life insurance company under the Internal Revenue
Code and includes the operations of the Separate Account in determining its

Note G - Year 2000 Contingency (Unaudited)

     Internal Systems. The Company's ultimate parent, American General
Corporation (AGC), has numerous technology systems that are managed on a
decentralized basis. AGC's Year 2000 readiness efforts are therefore being
undertaken by its key business units with centralized oversight. Each business
unit, including the Company, has developed and is implementing a plan to
minimize the risk of a significant negative impact on its operations.

     While the specifics of the plans vary, the plans include the following
activities: (1) perform an inventory of the Company's information technology and
non-information technology systems; (2) assess which items in the inventory may
expose the company to business interruptions due to Year 2000 issues; (3)
reprogram or replace systems that are not Year 2000 ready; (4) test systems to
prove that they will function into the next century as they do currently; and
(5) return the systems to operations. As of December 31, 1998, substantially all
of the Company's critical systems are Year 2000 ready and have been returned to
operations. However, activities (3) through (5) for certain systems are ongoing,
with vendor upgrades expected to be received during the first half of 1999.

     Third Party Relationships. The Company has relationships with various third
parties who must also be Year 2000 ready.  These third parties provide (or
receive) resources and services to (or from) the Company and include
organizations with which the company exchanges information.  Third parties
include vendors of hardware, software, and information services; providers of
infrastructure services such as voice and data communications and utilities for
office facilities; investors; customers; distribution channels; and joint
venture partners. Third parties differ from internal systems in that the Company
exercises less, or no, control over Year 2000 readiness.  The Company has
developed a plan to assess and attempt to mitigate the risks associated with the
potential failure of third parties to achieve Year 2000 readiness.  The plan
includes the following activities:  (1) identify and classify third party
dependencies; (2) research, analyze, and document Year 2000 readiness for
critical third parties; and (3) test critical hardware and software products and
electronic interfaces. As of December 31, 1998, AGC has identified and assessed
approximately 700 critical third party dependencies, including those relating to
the Company.  A more detailed evaluation will be completed during the first
quarter 1999 as part of the Company's contingency planning efforts.  Due to the
various stages of third parties' Year 2000 readiness, the Company's testing
activities will extend through 1999.

NOTE G - YEAR 2000 CONTINGENCY (UNAUDITED) - CONTINUED

     Contingency Plans.  The Company has commenced contingency planning to
reduce the risk of Year 2000-related business failures.  The contingency plans,
which address both internal systems and third party relationships, include the
following activities:  (1) evaluate the consequences of failure of business
processes with significant exposure to Year 2000 risk; (2) determine the
probability of a year 2000-related failure for those processes that have a high
consequence of failure; (3) develop an action plan to complete contingency plans
for those processes that rank high in consequence and probability of failure;
and (4) complete the applicable action plans.  The Company is currently
developing contingency plans and expects to substantially complete all
contingency planning activities by April 30, 1999.

     Risks and Uncertainties.  Based on its plans to make internal systems ready
for Year 2000, to deal with third party relationships, and to develop
contingency actions, the Company believes that it will experience at most
isolated and minor disruptions of business processes following the turn of the
century.  Such disruptions are not expected to have a material effect on the
Company's future results of operations, liquidity, or financial condition.
However, due to the magnitude and complexity of this project, risks and
uncertainties exist and the Company is not able to predict a most reasonably
likely worst case scenario.  If conversion of the Company's internal systems is
not completed on a timely basis (due to non-performance by significant third-
party vendors, lack of qualified personnel to perform the Year 2000 work, or
other unforeseen circumstances in completing the Company's plans), or if
critical third parties fail to achieve Year 2000 readiness on a timely basis,
the Year 2000 issues could have a material adverse impact on the Company's
operations following the turn of the century.

     Costs.  Through December 31,1998, the Company has incurred, and anticipates
that it will continue to incur, costs for internal staff, third-party vendors,
and other expenses to achieve Year 2000 readiness.  The cost of activities
related to Year 2000 readiness has not had a material adverse effect on the
Company's results of operations or financial condition.  In addition, the
Company has elected to accelerate the planned replacement of certain systems as
part of the Year 2000 plans.  Costs of the replacement systems are being
capitalized and amortized over their useful lives, in accordance with the
Company's normal accounting policies.  These costs are not passed to Divisions
of the Separate Account.

                         Report of Independent Auditors

Board of Directors and Stockholder
American General Life Insurance Company


We have audited the accompanying consolidated balance sheets of American General
Life Insurance Company (an indirectly wholly owned subsidiary of American
General Corporation) and subsidiaries as of December 31, 1998 and 1997, and the
related consolidated statements of income, comprehensive income, shareholder's
equity, and cash flows for each of the three years in the period ended
December 31, 1998. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosure in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of American General
Life Insurance Company and subsidiaries at December 31, 1998 and 1997, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1998, in conformity with generally
accepted accounting principles.

NATURE OF OPERATIONS

American General Life Insurance Company (the "Company") is a wholly owned
subsidiary of AGC Life Insurance Company, which is a wholly owned subsidiary of
American General Corporation (the "Parent Company"). The Company's wholly owned
life insurance subsidiaries are American General Life Insurance Company of New
York ("AGNY") and The Variable Annuity Life Insurance Company ("VALIC"). During
1998, the Company formed a new wholly owned subsidiary, American General Life
Companies (AGLC), to provide management services to certain life insurance
subsidiaries of the Parent Company.

The Company offers a complete portfolio of the standard forms of universal life,
variable universal life, interest-sensitive whole life, term life, structured
settlements, and fixed and variable annuities throughout the United States. In
addition, a variety of equity products is sold through its wholly owned
broker/dealer, American General Securities, Inc. The Company serves the estate
planning needs of middle- and upper-income households and the insurance needs of
small- to medium-sized businesses. AGNY offers a broad array of traditional and
interest-sensitive insurance, in addition to individual annuity products. VALIC
provides tax-deferred retirement annuities and employer-sponsored retirement
plans to employees of health care, educational, public sector, and other not-
for-profit organizations throughout the United States.

1. ACCOUNTING POLICIES

1.1 PREPARATION OF FINANCIAL STATEMENTS

The consolidated financial statements have been prepared in accordance with
generally accepted accounting principles ("GAAP") and include the accounts of
the Company and its wholly owned subsidiaries. Transactions with the Parent
Company and other subsidiaries of the Parent Company are not eliminated from the
financial statements of the Company. All other material intercompany
transactions have been eliminated in consolidation.

The preparation of financial statements requires management to make estimates
and assumptions that affect amounts reported in the financial statements and
disclosures of contingent assets and liabilities. Ultimate results could differ
from those estimates.

1. ACCOUNTING POLICIES (CONTINUED)

1.2 STATUTORY ACCOUNTING

The Company and its wholly owned life insurance subsidiaries are required to
file financial statements with state regulatory authorities. State insurance
laws and regulations prescribe accounting practices for calculating statutory
net income and equity. In addition, state regulators may permit statutory
accounting practices that differ from prescribed practices. The use of such
permitted practices by the Company and its wholly owned life insurance
subsidiaries did not have a material effect on statutory equity at December 31,
1998.

Statutory financial statements differ from GAAP. Significant differences were as
follows (in thousands):

1. ACCOUNTING POLICIES (CONTINUED)

1.2 STATUTORY ACCOUNTING (CONTINUED)

The more significant differences between GAAP and statutory accounting
principles are that under GAAP: (a) acquisition costs related to acquiring new
business are deferred and amortized (generally in proportion to the present
value of expected gross profits from surrender charges and investment,
mortality, and expense margins), rather than being charged to operations as
incurred; (b) future policy benefits are based on estimates of mortality,
interest, and withdrawals generally representing the Company's experience, which
may differ from those based on statutory mortality and interest requirements
without consideration of withdrawals; (c) deferred tax assets and liabilities
are established for temporary differences between the financial reporting basis
and the tax basis of assets and liabilities, at the enacted tax rates expected
to be in effect when the temporary differences reverse; (d) certain assets
(principally furniture and equipment, agents' debit balances, computer software,
and certain other receivables) are reported as assets rather than being charged
to retained earnings; (e) acquisitions are accounted for using the purchase
method of accounting rather than being accounted for as equity investments; and
(f) fixed maturity investments are carried at fair value rather than amortized
cost. In addition, statutory accounting principles require life insurance
companies to establish an AVR and an IMR. The AVR is designed to address the
credit-related risk for bonds, preferred stocks, derivative instruments, and
mortgages and market risk for common stocks, real estate, and other invested
assets. The IMR is composed of investment- and liability-related realized gains
and losses that result from interest rate fluctuations. These realized gains and
losses, net of tax, are amortized into income over the expected remaining life
of the asset sold or the liability released.

1.3 INSURANCE CONTRACTS

The insurance contracts accounted for in these financial statements include
primarily long-duration contracts. Long-duration contracts include traditional
whole life, endowment, guaranteed renewable term life, universal life, limited
payment, and investment contracts. Long-duration contracts generally require the
performance of various functions and services over a period of more than one
year. The contract provisions generally cannot be changed or canceled by the
insurer during the contract period; however, most new contracts written by the
Company allow the insurer to revise certain elements used in determining premium
rates or policy benefits, subject to guarantees stated in the contracts.

            Notes to Consolidated Financial Statements (continued)



1. ACCOUNTING POLICIES (CONTINUED)

1.4 INVESTMENTS

FIXED MATURITY AND EQUITY SECURITIES

All fixed maturity and equity securities were classified as available-for-sale
and recorded at fair value at December 31, 1998, 1997, and 1996. After adjusting
related balance sheet accounts as if the unrealized gains (losses) had been
realized, the net adjustment is recorded in accumulated other comprehensive
income within shareholders' equity. If the fair value of a security classified
as available-for-sale declines below its cost and this decline is considered to
be other than temporary, the security is reduced to its fair value, and the
reduction is recorded as a realized loss.

During 1998, the Company maintained a trading portfolio of certain fixed
maturity securities. Trading securities are recorded at fair value. Unrealized
gains (losses), as well as realized gains (losses), are included in net
investment income. The Company held no trading securities at December 31, 1998,
and trading securities did not have a material effect on net investment income
in 1998.

MORTGAGE LOANS

Mortgage loans are reported at amortized cost, net of an allowance for losses.
The allowance for losses covers all non-performing loans and loans for which
management has a concern based on its assessment of risk factors, such as
potential non-payment or non-monetary default. The allowance is based on a loan-
specific review and a formula that reflects past results and current trends.

Loans for which the Company determines that collection of all amounts due under
the contractual terms is not probable are considered to be impaired. The Company
generally looks to the underlying collateral for repayment of impaired loans.
Therefore, impaired loans are considered to be collateral dependent and are
reported at the lower of amortized cost or fair value of the underlying
collateral, less estimated cost to sell.

POLICY LOANS

Policy loans are reported at unpaid principal balance.

            Notes to Consolidated Financial Statements (continued)



1. ACCOUNTING POLICIES (CONTINUED)

1.4 INVESTMENTS (CONTINUED)

INVESTMENT REAL ESTATE

Investment real estate is classified as held for investment or available for
sale, based on management's intent. Real estate held for investment is carried
at cost, less accumulated depreciation and impairment write-downs. Real estate
available for sale is carried at the lower of cost (less accumulated
depreciation, if applicable) or fair value less cost to sell.

INVESTMENT INCOME

Interest on fixed maturity securities and performing and restructured mortgage
loans is recorded as income when earned and is adjusted for any amortization of
premium or discount. Interest on delinquent mortgage loans is recorded as income
when received. Dividends are recorded as income on ex-dividend dates.

REALIZED INVESTMENT GAINS

Realized investment gains (losses) are recognized using the specific-
identification method.

1.5 SEPARATE ACCOUNTS

Separate Accounts are assets and liabilities associated with certain contracts,
principally annuities; for which the investment risk lies solely with the
contract holder. Therefore, the Company's liability for these accounts equals
the value of the account assets. Investment income, realized investment gains
(losses), and policyholder account deposits and withdrawals related to separate
accounts are excluded from the consolidated statements of income, comprehensive
income, and cash flows. Assets held in Separate Accounts are primarily shares in
mutual funds, which are carried at fair value based on the quoted net asset
value per share.

            Notes to Consolidated Financial Statements (continued)



1. ACCOUNTING POLICIES (CONTINUED)

1.6 DEFERRED POLICY ACQUISITION COSTS ("DPAC") AND COST OF INSURANCE PURCHASED
    ("CIP")

Certain costs of writing an insurance policy, including commissions,
underwriting, and marketing expenses, are deferred and reported as DPAC.

CIP represents the cost assigned to insurance contracts in force that are
acquired through the purchase of a block of business. At December 31, 1998, CIP
of $22.1 million was reported within other assets.

DPAC and CIP associated with interest-sensitive life contracts, insurance
investment contracts, and participating life insurance contracts is charged to
expense in relation to the estimated gross profits of those contracts. DPAC and
CIP associated with all other insurance contracts is charged to expense over the
premium-paying period or as the premiums are earned over the life of the
contract.

DPAC and CIP are adjusted for the impact on estimated future gross profits as if
net unrealized gains (losses) on securities had been realized at the balance
sheet date. The impact of this adjustment is included in accumulated other
comprehensive income within shareholder's equity.

The Company reviews the carrying amount of DPAC and CIP on at least an annual
basis. Management considers estimated future gross profits or future premiums,
expected mortality, interest earned and credited rates, persistency, and
expenses in determining whether the carrying amount is recoverable.

1.7 PREMIUM RECOGNITION

Most receipts for annuities and interest-sensitive life insurance policies are
classified as deposits instead of revenue. Revenues for these contracts consist
of mortality, expense, and surrender charges. Policy charges that compensate the
Company for future services are deferred and recognized in income over the
period earned, using the same assumptions used to amortize DPAC (see Note 1.6).

For limited-payment contracts, net premiums are recorded as revenue, and the
difference between the gross premium received and the net premium is deferred
and recognized in a constant relationship to insurance in force. For all other
contracts, premiums are recognized when due.

            Notes to Consolidated Financial Statements (continued)



1. ACCOUNTING POLICIES (CONTINUED)

1.8 OTHER ASSETS

Acquisition-related goodwill, which is included in other assets, is charged to
expense in equal amounts over 40 years. The carrying value of goodwill is
regularly reviewed by management for indicators of impairment in value. If facts
and circumstances suggest that goodwill is impaired, other than temporarily, the
Company assesses the fair value of the underlying assets and reduces goodwill
accordingly.

1.9 POLICY AND CONTRACT CLAIMS RESERVES

Substantially all of the Company's insurance and annuity liabilities relate to
long-duration contracts. The contracts normally cannot be changed or canceled by
the Company during the contract period.

For interest-sensitive life and insurance investment contracts, reserves equal
the sum of the policy account balance and deferred revenue charges. Reserves for
other contracts are based on estimates of the cost of future policy benefits.
Reserves are determined using the net level premium method. Interest assumptions
used to compute reserves ranged from 2.5% to 13.5% at December 31, 1998.

1.10 REINSURANCE

The Company limits its exposure to loss on any single insured to $2.5 million by
ceding additional risks through reinsurance contracts with other insurers. The
Company diversifies its risk of reinsurance loss by using a number of reinsurers
that have strong claims-paying ability ratings. If the reinsurer could not meet
its obligations, the Company would reassume the liability. The likelihood of a
material reinsurance liability being reassumed by the Company is considered to
be remote.

A receivable is recorded for the portion of benefits paid and insurance
liabilities that have been reinsured. Reinsurance recoveries on ceded
reinsurance contracts were $63 million, $25 million, and $24 million during
1998, 1997, and 1996, respectively.  The cost of reinsurance is recognized over
the life of the reinsured policies using assumptions consistent with those used
to account for the underlying policies.

1. ACCOUNTING POLICIES (CONTINUED)

1.10 REINSURANCE

Benefits paid and future policy benefits related to ceded insurance contracts
are recorded as reinsurance receivables. The cost of reinsurance is recognized
over the life of the underlying reinsured policies using assumptions consistent
with those used to account for the underlying policies.

1.11 PARTICIPATING POLICY CONTRACTS

Participating life insurance accounted for approximately 2% of life insurance in
force at December 31, 1998 and 1997.

The portion of earnings allocated to participating policyholders that cannot be
expected to inure to shareholders is excluded from net income and shareholder's
equity. Dividends to be paid on participating life insurance contracts are
determined annually based on estimates of the contracts' earnings. Policyholder
dividends were $4.9 million in 1998.

1.12 INCOME TAXES

The Company and its life insurance subsidiaries, together with certain other
life insurance subsidiaries of the Parent Company, are included in a life/non-
life consolidated tax return with the Parent Company and its noninsurance
subsidiaries. The Company participates in a tax sharing agreement with other
companies included in the consolidated tax return. Under this agreement, tax
payments are made to the Parent Company as if the companies filed separate tax
returns; and companies incurring operating and/or capital losses are reimbursed
for the use of these losses by the consolidated return group.

Deferred tax assets and liabilities are established for temporary differences
between the financial reporting basis and the tax basis of assets and
liabilities, at the enacted tax rates expected to be in effect when the
temporary differences reverse. The effect of a tax rate change is recognized in
income in the period of enactment. State income taxes are included in income tax
expense.

1.12 INCOME TAXES (CONTINUED)

A valuation allowance for deferred tax assets is provided if it is more likely
than not that some portion of the deferred tax asset will not be realized. An
increase or decrease in a valuation allowance that results from a change in
circumstances that causes a change in judgment about the realizability of the
related deferred tax asset is included in income. Changes related to
fluctuations in fair value of available-for-sale securities are included in the
consolidated statements of comprehensive income and accumulated other
comprehensive income in shareholder's equity.

1.13 ACCOUNTING CHANGES

During 1998, the Company adopted Statement of Financial Accounting Standards
(SFAS) 130, Reporting Comprehensive Income, which establishes standards for
reporting and displaying comprehensive income and its components in the
financial statements. The Company elected to report comprehensive income and its
components in a separate statement of comprehensive income. Adoption of this
statement did not change recognition or measurement of net income and,
therefore, did not impact the Company's consolidated results of operations or
financial position.

Effective December 31, 1998, the Company adopted SFAS 131, Disclosures about
Segments of an Enterprise and Related Information, which changes the way
companies report segment information. With the adoption of SFAS 131, the Company
reports division earnings exclusive of goodwill amortization, net realized
investment gains, and nonrecurring items. This methodology is consistent with
the manner in which management reviews division results. Adoption of this
statement did not impact the Company's consolidated results of operations or
financial position.

In June 1998, the Financial Accounting Standards Board issued SFAS 133,
Accounting for Derivative Instruments and Hedging Activities, which requires all
derivative instruments to be recognized at fair value as either assets or
liabilities in the balance sheet. Changes in the fair value of a derivative
instrument are to be reported as earnings or other comprehensive income,
depending upon the intended use of the derivative instrument. This statement is
effective for years beginning after June 15, 1999. Adoption of SFAS 133 is not
expected to have a material impact on the Company's consolidated results of
operations or financial position.

Actual maturities may differ from contractual maturities, since borrowers may
have the right to call or prepay obligations. In addition, corporate
requirements and investment strategies may result in the sale of investments
before maturity. Proceeds from sales of fixed maturities were $5.4 billion,
$14.8 billion, and $16.2 billion during 1998, 1997, and 1996, respectively.

2.4 MORTGAGE LOANS ON REAL ESTATE

Diversification of the geographic location and type of property collateralizing
mortgage loans reduces the concentration of credit risk. For new loans, the
Company requires loan-to-value ratios of 75% or less, based on management's
credit assessment of the borrower. The mortgage loan portfolio was distributed
as follows at December 31, 1998 and 1997:

A portion of life insurance income earned prior to 1984 is not taxable unless it
exceeds certain statutory limitations, is distributed as dividends, or unless
the income tax deferred status of such amount is modified by future tax
legislation. Such income, accumulated in policyholders' surplus accounts,
totaled $87.1 million at December 31, 1998. At current corporate rates, the
maximum amount of tax on such income is approximately $30.5 million. Deferred
income taxes on these accumulations are not required because no distributions
are expected.

5. FEDERAL INCOME TAXES (CONTINUED)

5.3 TAXES PAID

Income taxes paid amounted to approximately $159 million, $168 million, and $182
million in 1998, 1997, and 1996, respectively.

5.4 TAX RETURN EXAMINATIONS

The Parent Company and the majority of its subsidiaries file a consolidated
federal income tax return. The Internal Revenue Service ("IRS") has completed
examinations of the Parent Company's tax returns through 1988. The IRS is
currently examining tax returns for 1989 through 1996. In addition, the tax
returns of companies recently acquired are also being examined. Although the
final outcome of any issues raised in examination is uncertain, the Parent
Company believes that the ultimate liability, including interest, will not
materially exceed amounts recorded in the consolidated financial statements.

6. TRANSACTIONS WITH AFFILIATES (CONTINUED)

Various American General companies provide services to the Company, principally
mortgage servicing and investment management services, provided by American
General Investment Management Corporation on a fee basis. The Company paid
approximately $46,921,000, $33,916,000, and $22,083,000 for such services in
1998, 1997, and 1996, respectively. Accounts payable for such services at
December 31, 1998 and 1997 were not material. The Company rents facilities and
provides services on an allocated cost basis to various American General
companies. Beginning in 1998, amounts received by the Company from affiliates
include amounts received by its wholly-owned, non-life insurance subsidiary,
American General Life Companies (AGLC). AGLC provides shared services, including
technology and Year 2000-readiness, to a number of American General
Corporation's life insurance subsidiaries. The Company received approximately
$66,550,000, $6,455,000, and $1,255,000 for such services and rent in 1998,
1997, and 1996, respectively. Accounts receivable for rent and services at
December 31, 1998 and 1997 were not material.

The Company has 8,500 shares of $100 par value cumulative preferred stock
authorized and outstanding with an $80 dividend rate, redeemable at $1,000 per
share after December 31, 2000. The holder of this stock, The Franklin Life
Insurance Company ("Franklin"), an affiliated company, is entitled to one vote
per share, voting together with the holders of common stock.

During 1996, the Company's residential mortgage loan portfolio of $42 million
was sold to American General Finance, Inc., at carrying value plus accrued
interest.

7. STOCK-BASED COMPENSATION

Certain officers of the Company participate in American General Corporation's
stock and incentive plans which provide for the award of stock options,
restricted stock awards, performance awards, and incentive awards to key
employees. Stock options constitute the majority of such awards. Expense related
to stock options is measured as the excess of the market price of the stock at
the measurement date over the exercise price. The measurement date is the first
date on which both the number of shares that the employee is entitled to receive
and the exercise price are known. Under the stock option plans, no expense is
recognized, since the market price equals the exercise price at the measurement
date.

Under an alternative accounting method, compensation expense arising from stock
options would be measured at the estimated fair value of the options at the date
of grant. Had compensation expense for the stock options been determined using
this method, net income would have been as follows:

estimated at the date of grant using a Black-Scholes option pricing model. The
weighted average assumptions used to estimate the fair value of the stock
options were as follows:

8. BENEFIT PLANS

8.1 PENSION PLANS

The Company has non-contributory defined benefit pension plans covering most
employees. Pension benefits are based on the participant's compensation and
length of credited service.

Equity and fixed maturity securities were 56% and 30%, respectively, of the
plans' assets at the plans' most recent balance sheet dates. Additionally, 1% of
plan assets were invested in general investment accounts of the Parent Company's
subsidiaries through deposit administration insurance contracts.

POSTRETIREMENT BENEFITS OTHER THAN PENSIONS

The Company has life, medical, supplemental major medical, and dental plans for
certain retired employees and agents. Most plans are contributory, which retiree
contributions adjusted annually to limit employer contributions to predetermined
amounts. The Company has reserved the right to change or eliminate these
benefits at any time.

8. BENEFIT PLANS (CONTINUED)

8.2 POSTRETIREMENT BENEFITS OTHER THAN PENSIONS (CONTINUED)

The life plans are insured through December 31, 1999. A portion of the retiree
medical and dental plans is funded through a voluntary employees' beneficiary
association (VEBA); the remainder is unfunded and self-insured. All of the
retiree medical and dental plans' assets held in the VEBA were invested in
readily marketable securities at its most recent balance sheet date.

Postretirement benefit expense in 1998, 1997, and 1996 was $60,000, $601,000,
and $844,000, respectively. The accrued liability for postretirement benefits
was $19.2 million and $3.8 million at December 31, 1998 and 1997, respectively.
These liabilities were discounted at the same rates used for the pension plans.

9. DERIVATIVE FINANCIAL INSTRUMENTS

9.1 USE OF DERIVATIVE FINANCIAL INSTRUMENTS

The Company's use of derivative financial instruments is generally limited to
reducing its exposure to interest rate and currency exchange risk by utilizing
interest rate and currency swap agreements, and options to enter into interest
rate swap agreements (called swaptions). The Company accounts for these
derivative and financial instruments as hedges. Hedge accounting requires a high
correlation between changes in fair values or cash flows of the derivative
financial instrument and the specific item being hedged, both at inception and
throughout the life of the hedge.

9.2 INTEREST RATE AND CURRENCY SWAP AGREEMENTS

Interest rate swap agreements are used to convert specific investment securities
from a floating to a fixed rate basis, or vice versa, and to hedge against the
risk of declining interest rates on anticipated security purchases. Interest
rate swap agreements are also used to convert a portion of floating-rate
borrowings to a fixed rate and to hedge against the risk of rising interest
rates on anticipated debt issuances.

Currency swap agreements are used to convert cash flows from specific investment
securities denominated in foreign currencies into U.S. dollars at specific
exchange rates, and to hedge against currency rate fluctuation on anticipated
security purchases.

            Notes to Consolidated Financial Statements (continued)



9. DERIVATIVE FINANCIAL INSTRUMENTS (CONTINUED)

9.2 INTEREST RATE AND CURRENCY SWAP AGREEMENTS (CONTINUED)

The difference between amounts paid and received on swap agreements is recorded
on an accrual basis as an adjustment to net investment income or interest
expense, as appropriate, over the periods covered by the agreements. The related
amount payable to or receivable from counterparties is included in other
liabilities or assets.

The fair values of swap agreements are recognized in the consolidated balance
sheet if the hedge investments are carried at fair value or if they hedge
anticipated purchases of such investments. In this event, changes in the fair
value of a swap agreement are reported in net unrealized gains on securities
included in other accumulated comprehensive income in shareholders' equity,
consistent with the treatment of the related investment security. The fair
values of swap agreements hedging debt are not recognized in the consolidated
balance sheet.

For swap agreements hedging anticipated investment purchases or debt issuances,
the net swap settlement amount or unrealized gain or loss is deferred and
included in the measurement of the anticipated transaction when it occurs.

Swap agreements generally have terms of two to ten years. Any gain or loss from
early termination of a swap agreement is deferred and amortized into income over
the remaining term of the related investment or debt. If the underlying
investment or debt is extinguished or sold, any related gain or loss on swap
agreements is recognized in income.

</TABLE>

9.3 CALL SWAPTIONS

Options to enter into interest rate swap agreements are used to limit the
Company's exposure to reduced spreads between investment yields and interest
crediting rates should interest rates decline significantly over prolonged
periods. During such periods, the spread between investment yields and interest
crediting rates may be reduced as a result of certain limitations on the
Company's ability to manage interest crediting rates. Call swaptions allow the
Company to enter into interest rate swap agreements to receive fixed rates and
pay lower floating rates, effectively increasing the spread between investment
yields and interest crediting rates.

Premiums paid to purchase call swaptions are included in investments and are
amortized to net investment income over the exercise period of the swaptions. If
a call swaption is terminated, any gain is deferred and amortized to insurance
and annuity benefits over the expected life of the insurance and annuity
contracts and any unamortized premium is charged to income. If a call swaption
ceases to be an effective hedge, any related gain or loss is recognized in
income.

</TABLE>

9.4 CREDIT AND MARKET RISK

Derivative financial instruments expose the Company to credit risk in the event
of non-performance by counterparties. The Company limits this exposure by
entering into agreements with counterparties having high credit ratings and by
regularly monitoring the ratings. The Company does not expect any counterparty
to fail to meet its obligation; however, non-performance would not have a
material impact on the Company's consolidated results of operations or financial
position.

The Company's exposure to market risk is mitigated by the offsetting effects of
changes in the value of the agreements and the related items being hedged.

10. FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)

The following methods and assumptions were used to estimate the fair value of
financial instruments:

     FIXED MATURITY AND EQUITY SECURITIES

     Fair values of fixed maturity and equity securities were based on quoted
     market prices, where available. For investments not actively traded, fair
     values were estimated using values obtained from independent pricing
     services or, in the case of some private placements, by discounting
     expected future cash flows using a current market rate applicable to yield,
     credit quality, and average life of investments.

     MORTGAGE LOANS ON REAL ESTATE

     Fair value of mortgage loans was estimated primarily using discounted cash
     flows, based on contractual maturities and risk-adjusted discount rates.

     POLICY LOANS

     Fair value of policy loans was estimated using discounted cash flows and
     actuarially determined assumptions, incorporating market rates.

     INVESTMENT IN PARENT COMPANY

     The fair value of the investment in Parent Company is based on quoted
     market prices of American General Corporation common stock.

     INSURANCE INVESTMENT CONTRACTS

     Fair value of insurance investment contracts was estimated using cash flows
     discounted at market interest rates.

10. FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)

     INDEBTEDNESS FROM AFFILIATES

     Indebtedness from affiliates is composed of accounts receivable and notes
     receivable from affiliates. Due to the short-term nature of accounts
     receivable, fair value is assumed to equal carrying value. Fair value of
     notes receivable was estimated using discounted cash flows based on
     contractual maturities and discount rates that were based on U.S. Treasury
     rates for similar maturity ranges.

11. DIVIDENDS PAID

American General Life Insurance Company paid $244 million, $401 million, and
$189 million in dividends on common stock to AGC Life Insurance Company in 1998,
1997, and 1996, respectively. The Company also paid $680 thousand per year in
dividends on preferred stock to an affiliate, The Franklin Life Insurance
Company, in 1998, 1997, and 1996.

12. RESTRICTIONS, COMMITMENTS, AND CONTINGENCIES

The Company and its insurance subsidiaries are restricted by state insurance
laws as to the amounts they may pay as dividends without prior approval from
their respective state insurance departments. At December 31, 1998,
approximately $3.3 billion of consolidated shareholder's equity represents net
assets of the Company which cannot be transferred, in the form of dividends,
loans, or advances to the Parent Company. Approximately $2.5 billion of
consolidated shareholders' equity is similarly restricted as to transfer from
its subsidiaries to the Company.

Generally, the net assets of the Company's subsidiaries available for transfer
to the Parent are limited to the amounts that the subsidiaries' net assets, as
determined in accordance with statutory accounting practices, exceed minimum
statutory capital requirements. However, payments of such amounts as dividends
may be subject to approval by regulatory authorities and are generally limited
to the greater of 10% of policyholders' surplus or the previous year's statutory
net gain from operations.

The Company has various leases, substantially all of which are for office space
and facilities. Rentals under financing leases, contingent rentals, and future
minimum rental commitments and rental expense under operating leases are not
material.

12. RESTRICTIONS, COMMITMENTS, AND CONTINGENCIES (CONTINUED)

In recent years, various life insurance companies have been named as defendants
in class action lawsuits relating to life insurance pricing and sales practices,
and a number of these lawsuits have resulted in substantial settlements. On
December 16, 1998, American General Corporation announced that certain of its
life insurance subsidiaries had entered into agreements to resolve all pending
market conduct class action lawsuits. The settlements are not final until
approved by the courts and any appeals are resolved. If court approvals are
obtained and appeals are not taken, it is expected the settlements will be final
in third quarter 1999.

In conjunction with the proposed settlements, the Company recorded a charge of
$97.1 million ($63.1 million after-tax) in the fourth quarter of 1998. The
charge covers the cost of policyholder benefits and other anticipated expenses
resulting from the proposed settlements, as well as other administrative and
legal costs.

On December 31, 1998, the Company entered into an agreement with the Parent
Company whereby the Company assigned, and the Parent Company assumed, $80.1
million of the liabilities of the Company related to the proposed resolution.
The liabilities of American General Life Insurance Company of New York, which
totaled $17.0 million, were not assumed by the Parent Company. As consideration
for the assumption of the liabilities, the Company paid the Parent Company an
amount equal to the liabilities recorded with respect to the proposed resolution
of the litigation. The assignment of the liabilities was not a novation, and
accordingly, the Company retains a contingent liability related to the
litigation. The litigation liabilities were reduced by payments of $2.7 million,
and the remaining balance of $94.4 million was included in other liabilities on
the Company's balance sheet at December 31, 1998.

The Company is party to various other lawsuits and proceedings arising in the
ordinary course of business. Many of these lawsuits and proceedings arise in
jurisdictions, such as Alabama and Mississippi, that permit damage awards
disproportionate to the actual economic damages incurred. Based upon information
presently available, the Company believes that the total amounts that will
ultimately be paid, if any, arising from these lawsuits and proceedings will not
have a material adverse effect on the Company's consolidated results of
operations and financial position. However, it should be noted that the
frequency of large damage awards, including large punitive damage awards, that
bear little or no relation to actual economic damages incurred by plaintiffs in
jurisdictions like Alabama and Mississippi continues to create the potential for
an unpredictable judgment in any given suit.

12. RESTRICTIONS, COMMITMENTS, AND CONTINGENCIES (CONTINUED)

The increase in the number of insurance companies that are under regulatory
supervision has resulted, and is expected to continue to result, in increased
assessments by state guaranty funds to cover losses to policyholders of
insolvent or rehabilitated insurance companies. Those mandatory assessments may
be partially recovered through a reduction in future premium taxes in certain
states. At December 31, 1998 and 1997, the Company has accrued $6.0 million and
$7.6 million, respectively, for guaranty fund assessments, net of $3.7 million
and $4.3 million, respectively, of premium tax deductions. The Company has
recorded receivables of $6.2 million and $9.7 million at December 31, 1998 and
1997, respectively, for expected recoveries against the payment of future
premium taxes. Expenses incurred for guaranty fund assessments were $3.6
million, $2.1 million, and $6.0 million in 1998, 1997, and 1996, respectively.

14. YEAR 2000 CONTINGENCY (UNAUDITED)

INTERNAL SYSTEMS

The Company's ultimate parent, American General Corporation, ("AGC") has
numerous technology systems that are managed on a decentralized basis. AGC's
Year 2000 readiness efforts are therefore being undertaken by its key business
units with centralized oversight. Each business unit, including the Company, has
developed and is implementing a plan to minimize the risk of a significant
negative impact on its operations.

While the specifics of the plans vary, the plans include the following
activities: (1) perform an inventory of the Company's information technology and
non-information technology systems; (2) assess which items in the inventory may
expose the Company to business interruptions due to Year 2000 issues; (3)
reprogram or replace systems that are not Year 2000 ready; (4) test systems to
prove that they will function into the next century as they do currently; and
(5) return the systems to operations. As of December 31, 1998, substantially all
of the Company's critical systems are Year 2000 ready and have been returned to
operations. However, activities (3) through (5) for certain systems are ongoing,
with vendor upgrades expected to be received during the first half of 1999.

THIRD PARTY RELATIONSHIPS

The Company has relationships with various third parties who must also be Year
2000 ready. These third parties provide, or receive resources and services to
(or from) the Company and include organizations with which the Company exchanges
information. Third parties include vendors of hardware, software, and
information services; providers of infrastructure services such as voice and
data communications and utilities for office facilities; investors, customers;
distribution channels; and joint venture partners. Third parties differ from
internal systems in that the Company exercises less, or no, control over Year
2000 readiness. The Company has developed a plan to assess and attempt to
mitigate the risks associated with the potential failure of third parties to
achieve Year 2000 readiness. The plan includes the following activities (1)
identify and classify third party dependencies; (2) research, analyze, and
document Year 2000 readiness for critical third parties; and (3) test critical
hardware and software products and electronic interfaces. As of December 31,
1998, AGC has identified and assessed more approximately 700 critical third
party dependencies, including those related to the Company. A more detailed
evaluation will be completed during the first quarter 1999 as part of the
Company's contingency planning efforts. Due to the various stages of third
parties' Year 2000 readiness, the Company's testing activities will extend
through 1999.

14. YEAR 2000 CONTINGENCY (UNAUDITED) (CONTINUED)

CONTINGENCY PLANS

The Company has commenced contingency planning to reduce the risk of Year 2000-
related business failures. The contingency plans, which address both internal
systems and third party relationships, include the following activities: (1)
evaluate the consequences of failure of business processes with significant
exposure to Year 2000 risk; (2) determine the probability of a Year 2000 related
failure for those processes that have a high consequence of failure; (3) develop
an action plan to complete contingency plans for those processes that rank high
in consequence and probability of failure; and (4) complete the applicable
actions plans. The Company is currently developing action plans and expects to
substantially complete all contingency planning activities by April 30, 1999.

RISKS AND UNCERTAINTIES

Based on its plans to make internal systems ready for Year 2000, to deal with
third party relationships, and to develop contingency action, the Company
believes that it will experience at most isolated and minor disruptions of
business processes following the turn of the century. Such disruptions are not
expected to have a material effect on the Company's future results of
operations, liquidity, or financial condition. However, due to the magnitude and
complexity of this project, risks and uncertainties exist and the Company is not
able to predict a most reasonably likely worst case scenario. If conversion of
the Company's internal systems is not completed on a timely basis (due to non-
performance by significant third party vendors, lack of qualified personnel to
perform the Year 2000 work, or other unforeseen circumstances in completing the
Company's plans), or if critical third parties fail to achieve Year 2000
readiness on a timely basis, the Year 2000 issue could have a material adverse
impact on the Company's operation following the turn of the century.

COSTS

Through December 31, 1998, the Company has incurred, and anticipates that it
will continue to incur, costs for internal staff, third-party vendors, and other
expenses to achieve Year 2000 readiness. The cost of activities related to Year
2000 readiness has not had a material adverse effect on the Company's results of
operations or financial condition. In addition, the Company has elected to
accelerate the planned replacement of certain systems as part of the Year 2000
plans. Costs of the replacement systems are being capitalized and amortized over
their useful lives, in accordance with the Company's normal accounting policies.

or in the right of the Company to procure a judgment in its favor by reason of
the fact that such person is or was acting on behalf of the Company, against
expenses actually and reasonably incurred by such person in connection with the
defense or settlement of such action if such person acted in good faith, in a
manner such person believed to be in the best interests of the Company, and with
such care, including reasonable inquiry, as an ordinarily prudent person in a
like position would use under similar circumstances.

No indemnification shall be made under Article VII, section 1: (a) in respect of
any claim, issue, or matter as to which such person shall have been adjudged to
be liable to the Company, unless and only to the extent that the court in which
such action was brought shall determine upon application that, in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity for the expenses which such court shall determine; (b) of amounts paid
in settling or otherwise disposing of a threatened or pending action with or
without court approval; or (c) of expense incurred in defending a threatened or
pending action which is settled or otherwise disposed of without court approval.

                                      C-14

Article VII, section 3, provides that, with certain exceptions, any
indemnification under Article VII shall be made by the Company only if
authorized in the specific case, upon a determination that indemnification of
the person is proper in the circumstances because the person has met the
applicable standard of conduct set forth in section 1 of Article VII by; (a) a
majority vote of a quorum consisting of directors who are not parties to such
proceeding; (b) approval of the shareholders, with the shares owned by the
person to be indemnified not being entitled to vote thereon; or (c) the court in
which such proceeding is or was pending upon application made by the Company or
the indemnified person or the attorney or other persons rendering services in
connection with the defense, whether or not such application by the attorney or
indemnified person is opposed by the Company.

Article VII, section 7, provides that for purposes of Article VII, those persons
subject to indemnification include any person who is or was a director, officer,
or employee of the Company, or is or was serving at the request of the Company
as a director, officer, or employee of another foreign or domestic corporation
which was a predecessor corporation of the Company or of another enterprise at
the request of such predecessor corporation.

Section 12 of the Trust Participation Agreement that is incorporated by
reference in Exhibit 3(c)(i) of this Registration Statement as amended by Form
of First Amendment to the Trust Participation Agreement that is filed as Exhibit
3(c)(ii) to this Registration Statement are hereby incorporated by reference in
response to this item.  Section 12.1 thereof provides that the Company will
indemnify The Sierra Variable Trust (the "Trust") and Sierra Investment Services
Corporation (the "Distributor") and their directors, trustees, officers and
controlling persons from losses and costs due to any misstatements or omissions
of material facts for which the Company is responsible in this Registration
Statement or otherwise or due to the Company's failure to meet its obligations
under the Trust Participation Agreement.  Section 12.2 thereof provides that the
Distributor will indemnify the Trust, the Company, American General Securities
Incorporated ("AGSI") and their officers, trustees, employees and controlling
persons from losses and costs due to any misstatements or omissions of material
facts for which the Distributor or its affiliates are responsible in this
Registration Statement or otherwise or as a result of any failure by the Trust
or the Distributor to meet its obligations under the Trust Participation
Agreement.

Section 6 of the Master Marketing and Distribution Agreement that is filed as
Exhibit 3(a)(ii) to this Registration Statement is hereby incorporated by
reference in response to this item.  Paragraph 5.1  thereof provides that the
Company and AGSI will indemnify the Distributor and any other broker-dealer
affiliated with the Distributor and contracted to sell the Contracts, and their
officers, directors and controlling persons from losses and costs due to any
misstatements or omissions of material facts for which the Company or AGSI is
responsible in this Registration Statement or due to any negligent, illegal or
fraudulent acts of the Company or AGSI.  Paragraph 5.2  provides that the
Distributor will indemnify the Company and AGSI, and their officers, directors
and controlling persons from losses and costs due to any misstatements or
omissions of material facts for which the Distributor or its affiliates are
responsible in this Registration Statement, or as a result of any negligent,
illegal or fraudulent acts or omissions by the Distributor.

The Agreement filed as Exhibit 3(d) to this Registration Statement is hereby
incorporated by reference in response to this item.  Pursuant to that Agreement,
the Distributor and Sierra Investment Advisors Corporation ("SIAC") agree to
indemnify the Company and AGSI with respect to liabilities arising out of the
negligence or bad faith of the Distributor, SIAC or any sub-investment adviser
to the Trust in performing their obligations to the Trust, including the
obligations of SIAC and the sub-investment

                                      C-15

advisers to operate the Trust in compliance with Sub-Chapter M and Section
817(h) of the Internal Revenue Code of 1986, as amended. The Distributor and the
Adviser also agree to indemnify the Company and AGSI for 50% of any other
liabilities or costs that they 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.

The Distribution Agreement filed as Exhibit 3(a)(i) to this Registration
Statement is hereby incorporated by reference in response to this item.  Under
part EIGHTH of that agreement, the Company agrees to indemnify AGSI from
liabilities and costs that it may incur as a result of any misstatements or
omissions of material facts in this Registration Statement or otherwise for
which the Company is responsible; and AGSI agrees to indemnify the Company
against costs and liabilities that the Company may incur as a result of any act
of an employee of AGSI.

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

<PAGE>
 
                                   AGREEMENT



THIS AGREEMENT ("Agreement") made as of October 2, 1998, is by and between WM
ADVISORS, INC., a Washington corporation ("Adviser") and AMERICAN GENERAL LIFE
INSURANCE COMPANY, a Texas corporation ("AGL").



                             W I T N E S S E T H:


WHEREAS, each of the investment companies listed on Schedule One hereto
("Schedule One," as the same may be amended from time to time), is registered as
an open-end management investment company under the Investment Company Act of
1940, as amended (the "Act") (such investment companies are hereinafter called
the "Funds," whether one or more); and

WHEREAS, each of the Funds is available as the investment vehicle for certain
separate accounts of AGL, established for variable life insurance policies
and/or variable annuity contracts offered by AGL (the "Separate Account,"
whether one or more); and

WHEREAS, AGL has entered into a participation agreement dated January 30, 1998
among AGL, American General Securities Incorporated, Advisor and the Funds (the
"Participation Agreement," as the same may be amended from time to time); and

WHEREAS, Adviser provides, among other things, investment advisory and/or
administrative services to the Funds; and

WHEREAS, WM Funds Distributors, Inc. (the "Underwriter") is underwriter of the
Funds; and

WHEREAS, Adviser desires AGL to provide the administrative services specified in
the attached Exhibit A ("Administrative Services"), in connection with the
ownership of interests of the Separate Account, which is the owner of shares of
the Funds for the benefit of persons who maintain their ownership interests in
the Separate Account through the WM Strategic Asset Manager Variable Annuity,
whose interests are included in the master account ("Master Account") referred
to in paragraph 1, of Exhibit A ("Shareholders"), and AGL is willing and able to
provide such Administrative Services on the terms and conditions hereinafter set
forth;

NOW, THEREFORE, in consideration of the premises and mutual covenants
hereinafter contained, each party hereto severally agrees as follows:



1.   AGL agrees to perform the Administrative Services specified in Exhibit A
     hereto for the benefit of the Shareholders.

2.   AGL represents and agrees that it will maintain and preserve all records as
     required by law to be maintained and preserved in connection with providing
     the Administrative Services, and will otherwise comply with all laws, rules
     and regulations applicable to the Administrative Services.
<PAGE>
 
3.   AGL agrees to provide copies of all the historical records relating to
     transactions between the Funds and Shareholders, and all written
     communications and other related materials regarding the Funds to or from
     such Shareholders, as reasonably requested by Adviser or its
     representatives (which representatives, include, without limitation, its
     auditors, legal counsel or the Underwriter), to enable Adviser or its
     representatives to monitor and review the Administrative Services performed
     by AGL, or comply with any request of the board of directors, or trustees
     or general partners (collectively, the "Directors") of any of the Funds, or
     of a governmental body, self-regulatory organization or Shareholder.

     In addition, AGL agrees that it will permit Adviser, the Funds or their
     representatives, to have reasonable access to its personnel and records in
     order to facilitate the monitoring of the quality of the Administrative
     Services.

4.   AGL may, with the consent of Adviser, contract with or establish
     relationships with other parties for the provision of the Administrative
     Services or other activities of AGL required by this Agreement, or the
     Participation Agreement, provided that AGL shall be fully responsible for
     the acts and omissions of such other parties.

5.   AGL hereby agrees to notify Adviser promptly if for any reason it is unable
     to perform fully and promptly any of its obligations under this Agreement.

6.   AGL hereby represents and covenants that it does not, and will not, own or
     hold or control with power to vote any shares of the Funds which are
     registered in the name of AGL or the name of its nominee and which are
     maintained in AGL variable annuity or variable life insurance accounts. AGL
     represents further that it is not registered as a broker-dealer under the
     Securities Exchange Act of 1934, as amended (the "1934 Act"), and it is not
     required to be so registered, including as a result of entering into this
     Agreement and performing the Administrative Services, and other obligations
     of AGL set forth in this Agreement.

7.   The provisions of the Agreement shall in no way limit the authority of
     Adviser, or any or the Funds or Underwriter to take such action as any of
     such parties may deem appropriate or advisable in connection with all
     matters relating to the operations of any of such Funds and/or sale of its
     shares.

8.   In consideration of the performance of the Administrative Services by AGL,
     Adviser agrees for as long as Adviser remains as investment adviser to the
     Funds, to pay AGL a monthly fee at an annual rate which shall equal .185%
     of the value of the average daily net assets of the Funds maintained in the
     Master Account for the Shareholders. The foregoing fee will be paid by
     Adviser to AGL on a calendar quarterly basis, and in this regard, payment
     of such fee will be made by Adviser to AGL within thirty (30) days
     following the end of each calendar quarter. The

                                       2
<PAGE>
 
     determination of applicable assets shall be made by averaging the daily net
     assets of the applicable portfolios of the Funds maintained in the Master
     Account for the Shareholders as of the last Business Day (as defined in the
     Participation Agreement) of each month falling within the applicable
     calendar quarter.

     Notwithstanding anything in this Agreement or the Participation Agreement
     appearing to the contrary, the payments by Adviser to AGL relate solely to
     the performance by AGL of the Administrative Services described herein
     only, and do not constitute payment in any manner for services provided by
     AGL to AGL policy or contract owners, or to any separate account organized
     by AGL, or for any investment advisory services, or for costs associated
     with the distribution of any variable annuity or variable life insurance
     contracts.

9.   AGL shall indemnify and hold harmless each of the Funds, Adviser and
     Underwriter and each of their respective officers, Directors, employees and
     agents from and against any and all losses, claims, damages, expenses, or
     liabilities that any one or more of them may incur including without
     limitation reasonable attorneys' fees, expenses and costs arising out of or
     related to the performance or non-performance by AGL of the Administrative
     Services under this Agreement.

10   This Agreement may be terminated without penalty at any time by AGL or by
     Adviser as to one or more of the Funds collectively, upon ninety (90) days
     written notice to the other party. Notwithstanding the foregoing, the
     provisions of paragraphs 2, 3, 9 and 11 of this Agreement, shall continue
     in full force and effect after termination of this Agreement.

     This Agreement shall not require AGL to preserve any records (in any medium
     or format) relating to this Agreement beyond the time periods otherwise
     required by the laws to which AGL or the Funds are subject provided that
     such records shall be offered to the Funds in the event AGL decides to no
     longer preserve such records following such time periods.

11.  After the date of any termination of this Agreement in accordance with
     paragraph 10 of this Agreement, no fee will be due with respect to any
     amounts first placed in the Master Account for the benefit of Shareholders
     after the date of such termination. However, notwithstanding any such
     termination, Adviser will remain obligated to pay AGL the fee specified in
     paragraph 8 of this Agreement, with respect to the value of the average
     daily net assets of each of the Funds maintained in the Master Account as
     of the date of such termination, for so long as such amounts are held in
     the Master Account, AGL continues to provide the Administrative Services
     with respect to such amounts in conformity with this Agreement and Advisor
     remains as the investment advisor to the funds. This Agreement, or any
     provision hereof, shall survive termination to the extent necessary for
     each party to perform its obligations with respect to amounts for which a
     fee continues to be due subsequent to such termination.

12.  AGL understands and agrees that the obligations of Adviser under this
     Agreement are not binding upon any of the Funds, upon any of their Board
     members or upon any shareholder of any of the Funds.

                                       3
<PAGE>
 
13.  It is understood and agreed that in performing the services under this
     Agreement AGL, acting in its capacity described herein, shall at no time be
     acting as an agent for Adviser, Underwriter or any of the Funds. AGL
     agrees, and agrees to cause its agents, not to make any representations
     concerning any of the Funds except those contained in the Funds' then-
     current prospectus; in current sales literature furnished by the Funds,
     Adviser or Underwriter to AGL; in the then current prospectus for a
     variable annuity contract or variable life insurance policy issued by AGL
     or then current sales literature with respect to such variable annuity
     contract or variable life insurance policy, approved by Adviser.

14.  This Agreement, including the provisions set forth herein in paragraph 8,
     may only be amended pursuant to a written instrument signed by the party to
     be charged. This Agreement may not be assigned by a party hereto, by
     operation of law or otherwise, without the prior written consent of the
     other party.

15.  This Agreement shall be governed by the laws of the State of Washington.

16.  This Agreement, including Exhibit A and Schedule One, constitutes the
     entire agreement between the parties with respect to the matters dealt with
     herein and supersedes any previous agreements and documents with respect to
     such matters. The parties agree that Schedule One may be replaced from time
     to time with a new Schedule One to accurately reflect any changes in the
     Funds available as investment vehicles under the Participation Agreement.

IN WITNESS HEREOF, the parties hereto have executed and delivered this Agreement
as of the date first above written.
