SYNOPSIS OF CONTRACT PROVISIONS

      This synopsis  should be read together  with the other  information  set
forth in this  Prospectus.  Variations due to requirements  particular to your
state are described in this Prospectus, or in your Contract, as appropriate.

      The Contracts are designed to provide  retirement  benefits  through the
accumulation  of purchase  payments on a fixed or variable  basis,  and by the
application  of such  accumulations  to  provide  Fixed  or  Variable  Annuity

Payments.

MINIMUM INVESTMENT REQUIREMENTS

      Your initial purchase payment must be at least $5,000. 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  interest in the Contract
and treat it as a full  surrender.  We also may transfer funds from a Division
(other than the Money Market Division) or Guarantee Period under your Contract
without  charge to the Money  Market  Division  if the  Account  Value of that
Division or Guarantee  Period  falls below $500.  See  "Contract  Issuance and
Purchase Payments."

PURCHASE PAYMENT ACCUMULATION

      Purchase payments will be accumulated 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  sixteen  available
Divisions of Separate  Account D. Each such Division  invests solely in shares
of one of sixteen  corresponding Series. See "The Series." As the value of the
investments  in  a  Series'  shares  increases  or  decreases,  the  value  of
accumulated   purchase  payments  allocated  to  the  corresponding   Division
increases or decreases,  subject to  applicable  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. While allocated
to a Guarantee Period, 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 eighteen 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.

FIXED AND VARIABLE ANNUITY PAYMENTS

      You may  elect to  receive  Fixed or  Variable  Annuity  Payments,  or a
combination  thereof,  commencing  on the  Annuity  Commencement  Date.  Fixed
Annuity Payments are periodic  payments from AGL, the amount of which is fixed
and  guaranteed  by AGL. The amount of the payments will depend on the Annuity
Payment Option chosen,  the age and, in some cases, sex 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  chosen in  connection  with a
variable  Annuity  Payment  Option.  If the net investment  return for a given
month exceeds


                                       9

<PAGE>

the assumed interest rate used in the Contract's  annuity tables,  the monthly
payment  will be greater  than the  previous  payment.  If the net  investment
return for a month is less than the assumed interest rate, the monthly payment
will be less than the previous payment.  The assumed interest rate used in the
Contract's  annuity tables is 3.5%. AGL may in the future 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

      Prior to the Annuity  Commencement  Date,  you may modify your  election
with  respect to the  allocation  of future  purchase  payments to each of the
various Divisions and Guarantee Periods, without charge.

      In addition,  you may reallocate  your Account Value among the Divisions
and Guarantee Periods prior to the Annuity Commencement Date. Transfers out of
a Guarantee  Period,  however,  are subject to limitations  as to amount.  For
these and other terms and conditions of transfer, see "Transfer, Surrender and
Partial Withdrawal of Owner Account Value - Transfers."

      After the Annuity  Commencement  Date, you may make transfers  among the
Divisions or to a fixed Annuity Payment Option, but you may not make transfers
from a fixed Annuity Payment  Option.  See "Annuity Period and Annuity Payment
Options - Transfers."

SURRENDERS, WITHDRAWALS AND CANCELLATIONS

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

      You may  cancel  your  Contract  by  delivering  it or mailing it with a
Written cancellation request to our Home Office or to the sales representative
through whom it was  purchased,  before the close of business on the tenth day
after you receive the Contract. (In some cases, the Contract may provide for a
20 or 30-day,  rather than a ten-day  period.) If the foregoing items are sent
by mail,  properly  addressed and postage  prepaid,  they will be deemed to be
received by us on the date actually received.

      We will refund to you the Owner Account Value plus any premium taxes and
Annual  Contract  Fee that have  been  deducted.  In  states  where the law so
requires,  however, we will refund the greater of that amount or the amount of
your purchase  payments,  or, if the law permits,  the amount of your purchase
payments.

DEATH PROCEEDS

      In the event  that the  Annuitant  or Owner  dies  prior to the  Annuity
Commencement  Date,  a benefit  is  payable  to the  Beneficiary.  See  "Death
Proceeds Prior to the Annuity Commencement Date."

LIMITATIONS IMPOSED BY RETIREMENT PLANS AND EMPLOYERS

      Certain rights you would  otherwise have under a Contract may be limited
by the terms of any applicable  employee benefit plan.  These  limitations may
restrict such things as total and partial surrenders,  the amount or timing of
purchase  payments that may be made, when annuity  payments must start and the
type  of  annuity  options  that  may be  selected.  Accordingly,  you  should
familiarize yourself with these and all other


                                      10

<PAGE>

aspects of any retirement plan in connection with which a Contract is used. We
are not responsible for monitoring or assuring  compliance with the provisions
of any retirement plan.

COMMUNICATIONS TO US

      All communications to us should include your Contract number,  your name
and, if different, the Annuitant's name. Communications may be directed to the
addresses and phone numbers on the cover of this Prospectus.

      Except as otherwise  specified in this Prospectus,  purchase payments or
other communications are deemed received at our Home Office on the actual date
of receipt there in proper form unless received (1) after the close of regular
trading  on The  New  York  Stock  Exchange  or (2)  on a date  that  is not a
Valuation  Date.  In either of these two cases,  the date of  receipt  will be
deemed to be the next Valuation Date.

PERFORMANCE INFORMATION

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

      The performance  information that may be presented is not an estimate or
guarantee of future  investment  performance and does not represent the actual
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  calculations  measure the net income of a
Division  plus the  effect  of any  realized  or  unrealized  appreciation  or
depreciation  of the underlying  investments in the Division for the period in
question.  Average annual total return figures are annualized and,  therefore,
represent the average annual  percentage  change in the value of an investment
in a Division  over the  applicable  period.  Total  return  figures  are also
annualized,  but do  not,  as  described  below,  include  the  effect  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.

      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
Division)   expressed  as  a  percentage  of  the  value  of  the   Division's
Accumulation  Units.  Yield is an  annualized  figure,  which means that it is
assumed  that the Division  generates  the same level of net income over a one
year period which is compounded on a semi-annual  basis.  The effective  yield
for the Money Market Division is calculated  similarly but includes the effect
of assumed  compounding.  The Money Market Division's  effective yield will be
slightly higher than its yield due to this compounding effect.

      Average  annual  total  return  figures  include  the  deduction  of all
recurring  charges  and  fees  applicable  under  the  Contract  to all  Owner
accounts,  including the Mortality and Expense Risk Charge, the Administrative
Expense Charge, the applicable Surrender Charge that may be imposed at the end
of the period in question, and a pro-rated portion of the Annual Contract Fee.
Yield,  effective yield,  total return, and cumulative total return figures do
not include the effect of any  Surrender  Charge that may be imposed  upon the
redemption of Accumulation  Units,  and thus may be higher than if such charge
were deducted. Total


                                      11

<PAGE>

return and  cumulative  total return figures also do not include the effect of
the Annual Contract Fee.

      DIVISION PERFORMANCE.  The investment performance for each Division that
invests in a  corresponding  Series of the Trust will  generally  reflect  the
investment  performance of that  corresponding  Series for the periods stated.
This information  appears in the Statement.  For periods prior to the date the
Contracts became available, the performance information for a Division will be
calculated on a hypothetical  basis by applying  current Separate Account fees
and  charges  under  the  Contract  to  the  historical   performance  of  the
corresponding  Series.  We may  waive or  reimburse  certain  fees or  charges
applicable to the Contract and such waivers or reimbursements will affect each
Divisions's performance results.

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

FINANCIAL RATINGS

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 their 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. An A++ rating
means,  in the opinion of A. M. Best,  that the insurer has  demonstrated  the
strongest  ability to meet its respective  policyholder and other  contractual
obligations.  A. M.  Best  publishes  Best's  Insurance  Reports,  Life-Health
Edition.

In addition,  the  claims-paying  ability of AGL as measured by the Standard &
Poor's  Corporation  may be  referred  to in  advertisements  or in reports to
Owners.  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 rating from Duff & Phelps Credit Rating Co.
A Duff & Phelps rating is an assessment of a company's insurance claims paying
ability. Duff & Phelps ratings range from AAA to CCC.


The ratings from A. M. Best,  Standard & Poors,  and Duff & Phelps reflect the
claims paying  ability and  financial  strength of AGL and are not a rating of
investment  performance that purchasers of insurance products have experienced
or are likely to experience in the future.

OTHER INFORMATION

      In addition, AGL may include in certain  advertisements  endorsements in
the  form  of a list of  organizations,  individuals  or  other  parties  that
recommend  the  Company  or the  Contracts.  AGL may  occasionally  include in
advertisements  comparisons of currently taxable and tax-deferred investment 7
programs,  based on selected  tax  brackets,  or  discussions  of  alternative
investment vehicles and general economic conditions.

                             FINANCIAL INFORMATION

      The financial  statements of AGL are located in the  Statement.  See the
cover page of the  Prospectus  for  information on how to obtain a copy of the
Statement.  The  financial  statements  of AGL  should be  considered  only as
bearing on the ability of AGL to meet its  contractual  obligations  under the
Contracts;  they do not bear on the investment performance of Separate Account
D.

      Financial  statements of AGL and Separate Account D, including financial
information  about the  Divisions  which invest in the Series of the Trust are
included  in  the   Statement.   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  (formerly  American
General Insurance Company),  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

      Separate  Account D was originally  established on November 19, 1973 and
consists of forty-three  Divisions,  sixteen of which are available  under the
Contracts offered by this Prospectus,  and twenty-seven of which are available
under  contracts  funded  through  Separate  Account D but not offered by this
Prospectus.  Separate Account D is registered with the Securities and Exchange
Commission as a unit investment trust under the 1940 Act.

      Each Division of Separate  Account D is part of AGL's  general  business
and the assets of  Separate  Account D belong to AGL.  Under Texas law and the
terms  of the  Contracts,  the  assets  of  Separate  Account  D  will  not be
chargeable  with  liabilities  arising out of any other business which AGL may
conduct, but will be held exclusively to meet AGL's obligations under variable
annuity contracts.  Furthermore, the income, gains, and losses, whether or not
realized, from assets allocated to Separate Account D, are, in accordance with
the Contracts,  credited to or charged  against the Separate  Account  without
regard to other income, gains, or losses of AGL.


                                  THE SERIES


   
      The  variable  benefits  under the  Contracts  are  funded by  seventeen
Divisions of the Separate  Account.  These Divisions invest in shares of eight
separate investment Series of the Trust and nine
    


                                      13

<PAGE>


   
separate  Series of the Fund.  The  Trust and the Fund  offer  shares of these
Series,  without sales  charges,  exclusively  to insurance  company  variable
annuity and variable life insurance  separate accounts and not directly to the
public.  The Trust and the Fund 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 Owners of Contracts 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 or the Fund could cause the  contracts  funded
through another  separate  account to lose their tax deferred  status,  unless
remedial  action  were taken.  If a material  irreconcilable  conflict  arises
between separate accounts,  a separate account may be required to withdraw its
participation  in the  Trust or the  Fund.  If it  becomes  necessary  for any
separate  account  to  replace  shares of the  Trust or the Fund with  another
investment,  the Trust or the Fund may have to liquidate portfolio  securities
on a  disadvantageous  basis. At the same time, the Trust's Board of Trustees,
the Fund's  Board of  Directors  and we will  monitor  events for any material
irreconcilable conflicts that may possibly arise and determine what action, if
any, should be taken to remedy or eliminate the conflict.
    

      Any dividends or capital gain  distributions  attributable  to Contracts
are  automatically  reinvested  in shares of the  Series  from  which they are
received at the Series' net asset value on the date  payable.  Such  dividends
and distributions will have the effect of reducing the net asset value of each
share of the corresponding Series and increasing,  by an equivalent value, the
number  of  shares  outstanding  of the  Series.  However,  the  value of your
interest in the corresponding Division will not change as a result of any such
dividends and distributions.

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

      Before selecting any Division,  you should carefully read the prospectus
that  includes  more  complete  information  about the  Series  in which  that
Division invests,  including investment  objectives and policies,  charges and
expenses.  You can find  information  about the investment  performance of the
Series of the Trust in the Statement and  information  about the experience of
the  investment  advisers to the Series of the Fund in the  prospectus for the
Fund.  You may obtain  additional  copies of such a prospectus  by  contacting
AGL's Annuity Administration  Department at the addresses and phone number set
forth on the cover page of this Prospectus.  When making your request,  please
specify the single or the several Series in which you are interested.

      High  yielding  fixed-income  securities  such as  those  in  which  the
Domestic Income Portfolio  invests are subject to greater market  fluctuations
and risk of loss of income and principal  than  investments  in lower yielding
fixed-income securities. Potential investors in this Division should carefully
read the  prospectus  and related  statement of  additional  information  that
pertains  to this  Series and  consider  their  ability to assume the risks of
making an investment in this Division.

VOTING PRIVILEGES

      The Owner prior to the Annuity  Commencement  Date and the  Annuitant or
other payee during the Annuity Period will be entitled to give us instructions
as to  how  Series  shares  held  in  the  Divisions  of  Separate  Account  D
attributable  to their Contract should be voted at meetings of shareholders of
the Series.  Those persons entitled to give voting instructions and the number
of votes for  which  they may give  directions  will be  determined  as of the
record  date for a  meeting.  Separate  Account D will vote all shares of each
Series that it holds of record in accordance with  instructions  received with
respect to all AGL annuity contracts participating in that Series.

      Separate Account D will also vote all shares of each Series for which no
instructions  have been  received for or against any  proposition  in the same
proportion as the shares for which voting instructions were received.


                                      15

<PAGE>

      Prior to the Annuity  Commencement  Date, the number of votes each Owner
is entitled to direct with respect to a particular  Series is equal to (a) the
Owner's Variable Account Value  attributable to that Series divided by (b) the
net asset  value of one share of that  Series.  In  determining  the number of
votes,  fractional votes will be recognized.  While a variable Annuity Payment
Option is in effect,  the number of votes an Annuitant or payee is entitled to
direct with  respect to a  particular  Series will be computed in a comparable
manner,  based on our  liability  for future  Variable  Annuity  Payments with
respect to that  Annuitant or payee as of the record date.  Such liability for
future  payments will be calculated on the basis of the mortality  assumptions
and the assumed  interest rate used in determining the number of Annuity Units
under a Contract  and the  applicable  value of an Annuity  Unit on the record
date.

      Series shares held by insurance  company  separate  accounts  other than
Separate Account D will generally be voted in accordance with  instructions of
participants in such other separate accounts.

      We believe that AGL's voting instruction  procedures comply with current
federal securities law requirements and interpretations thereof.  However, AGL
reserves the right to modify these  procedures in any manner  consistent  with
applicable legal  requirements and  interpretations  as in effect from time to
time.

                               THE FIXED ACCOUNT

      AMOUNTS IN THE FIXED ACCOUNT OR SUPPORTING FIXED ANNUITY PAYMENTS BECOME
PART OF OUR GENERAL ACCOUNT. BECAUSE OF EXEMPTIVE AND EXCLUSIONARY PROVISIONS,
INTERESTS IN THE GENERAL ACCOUNT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, NOR IS THE GENERAL  ACCOUNT  REGISTERED AS AN INVESTMENT  COMPANY
UNDER THE 1940 ACT. WE HAVE BEEN ADVISED THAT THE STAFF OF THE  SECURITIES AND
EXCHANGE  COMMISSION HAS NOT REVIEWED THE  DISCLOSURES IN THIS PROSPECTUS THAT
RELATE TO THE FIXED ACCOUNT OR FIXED ANNUITY PAYMENTS.  DISCLOSURES  REGARDING
THESE  MATTERS,  HOWEVER,  MAY  BE  SUBJECT  TO  CERTAIN  GENERALLY-APPLICABLE
PROVISIONS  OF THE  FEDERAL  SECURITIES  LAWS  RELATING  TO THE  ACCURACY  AND
COMPLETENESS OF STATEMENTS IN PROSPECTUSES.

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

      Our obligations with respect to the Fixed Account are legal  obligations
of AGL and are  supported by our General  Account  assets,  which also support
obligations  incurred  by us under  other  insurance  and  annuity  contracts.
Investments  purchased  with amounts  allocated  to the Fixed  Account are the
property of AGL, and Owners have no legal rights in such investments.

      Account  Value that is allocated by the Owner to the Fixed Account earns
a Guaranteed  Interest Rate commencing with the date of such allocation.  This
Guaranteed Interest Rate continues for a number of years selected by the Owner
from among the Guarantee Periods that we then offer. At the end of a Guarantee
Period, the Owner's Account Value in that Guarantee Period, including interest
accrued  thereon,  will be  allocated  to a new  Guarantee  Period of the same
length  unless AGL has  received a Written  request from the Owner to allocate
this  amount to a different  Guarantee  Period or Periods or to one or more of
the Divisions of Separate  Account D. We must receive this Written  request at
least three  business  days prior to the end of the Guarantee  Period.  If the
Owner has not provided such Written request and the renewed  Guarantee  Period
extends beyond the scheduled Annuity  Commencement  Date, we will nevertheless
contact the Owner regarding the scheduled  Annuity  Commencement  Date. If the
Owner elects to annuitize in this  circumstance,  the Surrender  Charge may be
waived. (See "Annuity Payment Options" and "Surrender  Charge.") 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 at least 30 days
and not more than 60 days  prior to 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  automatically  transfer  without  charge,  the  balance to the Money
Market Division at the end of that Guarantee Period, unless


                                      16

<PAGE>

we have received in good order Written  instructions  to transfer such balance
to a different Division.

      We declare  the  Guaranteed  Interest  Rates from time to time as market
conditions  dictate.  We advise an Owner of the Guaranteed Interest Rate for a
chosen Guarantee Period at the time a purchase payment is received, a transfer
is effectuated or a Guarantee Period is renewed.  A different rate of interest
may be credited to one Guarantee Period than to another  Guarantee Period that
is the same length but that began on a different date. The minimum  Guaranteed
Interest Rate is an effective annual rate of 3%.

   
      Each Guarantee  Period has its own Guaranteed  Interest Rate,  which may
differ from those for other Guarantee  Periods.  From time to time we will, at
our  discretion,  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  commenced.
Each allocation or transfer of an amount to a Guarantee  Period  commences the
running of a new Guarantee Period with respect to that amount, which 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.  One or more  Guarantee
Periods may be offered 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 Guarantee  Periods that we
are making available at any time.
    

      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.

      Information  concerning the Guaranteed  Interest Rates applicable to the
various  Guarantee  Periods  at any  time  may be  obtained  from  your  sales
representative  or from the  addresses or phone numbers set forth on the cover
page of this Prospectus.

                    CONTRACT ISSUANCE AND PURCHASE PAYMENTS

      The  minimum  initial  purchase  payment  is  $5,000.  The amount of any
subsequent purchase payment allocated to any Division or Guarantee Period must
be at least  $100.  We  reserve  the right to modify  these  minimums,  in our
discretion.

      An  application  to purchase a Contract  must be made by signed  Written
application  form  provided by AGL or by such other medium or format as may be
agreed  to by AGL  and Van  Kampen  American  Capital  Distributors,  Inc.  as
distributor  of  the  Contracts.   When  a  purchase  payment  accompanies  an
application to purchase a Contract and the application is properly  completed,
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 the application is not complete or is incorrectly completed,  we will
request additional  documents or information within five Valuation Dates after
receipt  of the  application  at our  Home  Office.  If a  correctly-completed
application is not received  within five Valuation  Dates after receipt of the
purchase  payment at our Home  Office,  we will  return the  purchase  payment
immediately  unless the  prospective  purchaser  specifically  consents to our
retaining the purchase  payment until the  application  is made  complete,  in
which  case the  initial  purchase  payment is  credited  as of the end of the
Valuation  Period in which we receive at our Home Office the last  information
required to process the application. Subsequent purchase payments are credited
as of the end of the Valuation  Period in which they and any required  Written
identifying information, are received at our


                                      17

<PAGE>

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

      If the Owner's 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  Division.  If the
Owner's  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
Division,  Divisions or Fixed  Account to which the  transfer was made.  These
minimum requirements are waived for transfers under the Automatic  Rebalancing
program. See "Automatic Rebalancing." If the Owner's total Account Value falls
below  $500,  we may  cancel  the  Contract.  Such  a  cancellation  would  be
considered 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 need make no
further purchase payments. You may, however, elect to make subsequent purchase
payments  at any time  prior to the  Annuity  Commencement  Date and while the
Owner and Annuitant are still living.  Checks for subsequent purchase payments
should  be made  payable  to  American  General  Life  Insurance  Company  and
forwarded  directly to our Home Office.  We also accept  purchase  payments by
wire or by exchange from another  insurance  company.  You may obtain  further
information  about how to make  purchase  payments by either of these  methods
from your  sales  representative  or from us at the  addresses  and  telephone
numbers on the cover page of this Prospec tus.  Purchase  payments pursuant to
salary reduction plans may be made only with our agreement.

      Your  purchase  payments  begin to earn a  return  in the  Divisions  of
Separate  Account D or the  Guarantee  Periods 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 is to be allocated to each Division and each  Guarantee  Period.  You can
change these allocation percentages at any time by Written notice to us.


                              OWNER ACCOUNT VALUE

      Prior to 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

      Your  Variable  Account  Value  as of any  Valuation  Date  prior to the
Annuity  Commencement  Date is the sum of your Variable Account Values in each
Division of Separate Account D as of that date. Your Variable Account Value in
any such 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 Separate  Account D, you bear
the entire risk of investment losses.

      Accumulation  Units in a Division  are credited to you when you allocate
purchase  payments or transferred  amounts to that Division.  Similarly,  such
Accumulation Units are canceled to the extent you transfer or withdraw amounts
from a Division or to the extent  necessary to pay certain  charges  under the
Contract.  The crediting or cancellation of Accumulation Units is based on the
value of such Accumulation  Units at the end of the Valuation Date as of which
the related  amounts are being  credited to or charged  against your  Variable
Account Value, as the case may be.


                                      18

<PAGE>

      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 with respect to 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 as
determined at the end of the previous  Valuation Period,  and subtracting from
that  result  a factor  representing  the  mortality  risk,  expense  risk and
administrative expense charge.

FIXED ACCOUNT VALUE

      Your Fixed Account  Value as of any Valuation  Date prior to the Annuity
Commencement  Date is the sum of your Fixed  Account  Value in each  Guarantee
Period as of that date.  Your Fixed Account  Value in any 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.

      The Fixed Account Value is guaranteed by AGL.  Therefore,  AGL bears the
investment risk with respect to 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 minimum  Guaranteed  Interest Rate stated in
your Contract).

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

TRANSFERS

      Commencing 30 days after the  Contract's  date of issue and prior to the
Annuity  Commencement  Date,  you may transfer  your Account Value at any time
among the available  Divisions of Separate  Account D and  Guarantee  Periods,
subject to the conditions described below. Such transfers will be effective at
the end of the Valuation  Period in which we receive your Written or telephone
transfer request.

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

      Prior to the  Annuity  Commencement  Date and  after  the  first 30 days
following  the  date  the  Contract  was  issued,  you may  make up to  twelve
transfers each Contact Year without charge,  but additional  transfers will be
subject  to a $25  charge.  Also,  no more than 25% of the  Account  Value you
allocated to a Guarantee Period at its inception may be transferred during any
Contract  Year.  This 25%  limitation  does not  apply to  transfers  from the
one-year Guarantee Period, to transfers within 15 days before or after the end
of the Guarantee Period in which the transferred amounts were being held or to
a renewal at the end of the Guarantee Period to the same Guarantee Period.

   
      Subject  to the  above  general  rules  concerning  transfers,  you  may
establish an automatic transfer plan,
    

                                      19

<PAGE>

   
whereby  amounts are  automatically  transferred  by us from the Money  Market
Division or the one-year  Guarantee Period (or any other Guarantee Period that
is  available  at that  time) to one or more  other  Divisions  on a  monthly,
quarterly,  semi-annual or annual basis. This kind of automatic  transfer plan
is also  referred to as a dollar cost  averaging  plan,  under which the Owner
will  select  the amount to be  transferred  and the period of time over which
transfers are to occur. We may offer certain  automatic  transfer plans to new
Contract Owners who are not presently  owners of any annuity  contract offered
by AGL or an affiliate of AGL. Under such plans,  we will establish the period
of time over which equal monthly  transfers  will be made,  and we may offer a
higher Guaranteed  Interest Rate, set forth in a prospectus  supplement,  than
would otherwise be available for another Guarantee Period of the same duration
that is not offered under such plans.  Transfers under such automatic transfer
plan will not count towards the twelve free  transfers each Contract Year, and
will not incur a $25 charge.  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  front  cover  of  this
Prospectus.

      If the  person or  persons  that are  entitled  to make  transfers  have
provided a Written request for the Telephone  Transfer  Privilege form that is
on file with us,  transfers  may be made  pursuant to telephone  instructions,
subject to the terms of the Telephone  Transfer  Privilege  authorization.  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
unauthorized  persons use this  service in your name.  Currently we attempt to
limit the availability of telephone transfer instructions only to the Owner of
the Contract for which instruction is received.  Under the Telephone  Transfer
Privilege we are not liable for any acts or omissions based upon  instructions
that we reasonably believe to be genuine, including 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,  the identity of the caller,  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.  If  several
persons seek to effect  telephone  transfers at or about the same time,  or if
our recording equipment  malfunctions,  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, if, due to malfunction or other circumstances,
the  recording  of  your   telephone   request  is  incomplete  or  not  fully
comprehensible,  we will not process  the  transaction.  The phone  number for
telephone exchanges is 1-800-200-3883.
    

      The   Contracts  are  not  designed  for   professional   market  timing
organizations or other entities utilizing  programmed and frequent  transfers.
We  reserve  the right at any time and  without  prior  notice to any party to
terminate, suspend, or modify our policy regarding transfers.

AUTOMATIC REBALANCING

      Automatic  Rebalancing  within the  Separate  Account is  available  for
Contracts  with an  Account  Value  of  $25,000  and  larger  at the  time the
application for Automatic  Rebalancing is received.  Application for Automatic
Rebalancing can be made either at issue or after issue,  and may  subsequently
be discontinued.

      Automatic  Rebalancing occurs when funds are transferred by us among the
Separate  Account  Divisions  so that the  values in each  Division  match the
Owner's  percentage  allocation  for  Automatic  Rebalancing  then in  effect.
Automatic  Rebalancing  is  available on a  quarterly,  semi-annual  or annual
basis,  measured from the Contract  Anniversary  date. A Contract  Anniversary
date which falls on the 29th, 30th, or 31st of the month


                                      20

<PAGE>

will  result  in  Automatic  Rebalancing  as of 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
twelve free transfers each Contract Year, and will not incur a $25 charge.

SURRENDERS AND PARTIAL WITHDRAWALS

      At any time  prior  to the  Annuity  Commencement  Date  and  while  the
Annuitant is still living,  the Owner may make a full  surrender of or partial
withdrawal from his or her Contract.

      The  amount  payable  to the Owner upon full  surrender  is the  Owner's
Account Value at the end of the Valuation Period in which we receive a Written
surrender request in good order, minus any applicable  Surrender Charge, minus
the amount of 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  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  with  respect  to the  Contract  will
terminate,  subject  to a right to  reinstate  the  Contract.  (See  "One-Time
Reinstatement  Privilege.") All collateral assignees of record must consent to
any full surrender or partial withdrawal.

      Your  Written  request  for a  partial  withdrawal  should  specify  the
Divisions  of  Separate  Account  D, or the  Guarantee  Periods  of the  Fixed
Account,  from which you wish the partial withdrawal to be made. If you do not
specify,  or if  the  withdrawal  cannot  be  made  in  accordance  with  your
specification,  to the extent  necessary the withdrawal will be taken pro-rata
from the Divisions and Guarantee Periods, based on your Account Value in each.
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 Division), we reserve the right to transfer,  without charge, the
remaining balance to the Money Market Division.  Unless you request otherwise,
upon a partial withdrawal, your Accumulation Units and Fixed Account interests
that  are  cancelled  will  have a total  value  equal  to the  amount  of the
withdrawal request,  plus any Surrender Charge, and premium tax if applicable,
payable upon the partial  withdrawal.  The amount  payable to you,  therefore,
will be the amount of the withdrawal request.

      We also make available a systematic  withdrawal plan under which you may
make  automatic  partial  withdrawals  at  periodic  intervals  in a specified
amount,  subject  to the  terms and  conditions  applicable  to other  partial
withdrawals.  Additional  information about how to establish such a systematic
withdrawal plan may be obtained from your sales  representative  or from us at
the  addresses  and  phone  numbers  set  forth  on the  cover  page  of  this
Prospectus.  We reserve the right to modify or terminate  our  procedures  for
systematic withdrawals at any time.

      The  Code  provides  that a  penalty  tax  will be  imposed  on  certain
premature  surrenders or  withdrawals.  For a discussion of this and other tax
implications of total surrenders and systematic and other partial withdrawals,
including withholding requirements, see "Federal Income Tax Matters."

                  ANNUITY PERIOD AND ANNUITY PAYMENT OPTIONS

ANNUITY COMMENCEMENT DATE

      The Owner may select the  Annuity  Commencement  Date when  applying  to
purchase a Contract and


                                      21

<PAGE>

may change a previously-selected date at any time prior to the beginning of an
Annuity  Payment  Option by submitting a Written  request,  subject to Company
approval.  The Annuity Commencement Date may be any day of any month up to the
Annuitant's  one  hundredth  birthday  inclusive.  (Pennsylvania  has  special
limitations which may require the Annuity  Commencement Date to be as early as
age 85 but in no event beyond age 90.) See "Federal  Income Tax Matters" for a
description  of the penalties  that may attach to  distributions  prior to the
Annuitant's  attaining  age 59 1/2 under any  Contract or after April 1 of the
year  following the calendar  year in which the  Annuitant  attains age 70 1/2
under 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, if you give us other
Written  instructions  at least thirty days prior to the Annuity  Commencement
Date, we will apply your Account Value in different proportions.

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


FIXED AND VARIABLE ANNUITY PAYMENTS

      The amount of the first monthly Fixed or Variable  Annuity  Payment will
be at least as favorable as that  produced by the annuity  tables set forth in
the  Contract,  based on the amount of your  Account  Value that is applied to
provide the Fixed or Variable Annuity Payments. Thereafter, the amount of each
monthly  Fixed  Annuity  Payment  is fixed and  specified  by the terms of the
Annuity Payment Option selected.

      The Account Value that is applied to provide  Variable  Annuity Payments
is converted to a number of Annuity  Units by dividing the amount of the first
Variable  Annuity  Payment  by the value of an  Annuity  Unit of the  relevant
Division as of the end of the  Valuation  Period that  includes  the tenth day
prior  to  the  Annuity  Commencement  Date.  This  number  of  Annuity  Units
thereafter  remains constant with respect to any Annuitant,  and the amount of
each subsequent  Variable  Annuity  Payment is determined by multiplying  this
number by the value of an Annuity Unit as of the end of the  Valuation  Period
that contains the tenth day prior to the date of each payment. If the Variable
Annuity Payments are based on more than one Division,  these  calculations are
performed  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.

      As a result of the foregoing computations,  if the net investment return
for a  Division  for any month is at an annual  rate of more than the  assumed
interest rate used in the  Contract's  annuity  tables,  any Variable  Annuity
Payment  based on that  Division  will be greater  than the  Variable  Annuity
Payment based on that Division for the previous  month.  If the net investment
return  for a  Division  for any month is at an  annual  rate of less than the
assumed  interest rate used in the  Contract's  annuity  tables,  any Variable
Annuity Payment based on that Division will be less than the Variable  Annuity
Payment based on that Division for the previous month.

ANNUITY PAYMENT OPTIONS

      The Owner may  elect to have  annuity  payments  made  beginning  on the
Annuity  Commencement  Date  under  any  one of the  Annuity  Payment  Options
described below. We will notify the Owner 60 to 90 days prior to the scheduled
Annuity  Commencement  Date that the  Contract  is  scheduled  to mature,  and
request  that an  Annuity  Payment  Option be  selected.  If the Owner has not
selected an Annuity Payment Option ten days prior to the Annuity  Commencement
Date, we will proceed as follows:  (1) if the scheduled  Annuity  Commencement
Date is any date prior to the  Annuitant's  one  hundredth  birthday,  we will
extend  the  Annuity  Commencement  Date  to  the  Annuitant's  one  hundredth
birthday; or (2) if the scheduled Annuity Commencement Date is the Annuitant's
one  hundredth  birthday,  the Account Value less any  applicable  charges and
premium  taxes  will  be  paid  in one sum to the  Owner.  This  procedure  is
different in Pennsylvania  because the Annuity Commencement Date cannot exceed
age 90.

      The Code imposes minimum  distribution  requirements that have a bearing
on the  Annuity  Payment  Option  that  should be chosen  in  connection  with
Qualified Contracts.  See "Federal Income Tax Matters." We are not responsible
for  monitoring  or advising  Owners as to whether  the  minimum  distribution
requirements are being met, unless we have received a specific Written request
to do so.

      No election of any Annuity  Payment Option may be made unless an initial
annuity  payment of at least $100 would be provided,  where only Fixed or only
Variable  Annuity  Payments  are  elected,  and  $50  on  each  basis  when  a
combination  of Variable  and Fixed  Annuity  Payments  is  elected.  If these
minimums are not met, we will first reduce the frequency of annuity  payments,
and if the minimums are still not met, we will make a lump-sum  payment to the
Annuitant  or other  properly-designated  payee in the  amount of the  Owner's
Account Value, less any applicable  Surrender Charge,  any uncollected  Annual
Contract Fee, and any applicable premium tax.

      The Owner, or if the Owner has not done so, the Beneficiary  may, within
60 days after the death of the Owner or  Annuitant,  elect that any amount due
to the  Beneficiary be applied under any option  described  below,  subject to
certain  tax  law  requirements.   See  "Death  Proceeds."   Thereafter,   the
Beneficiary  will have all the remaining  rights and powers under the Contract
and be  subject to all the terms and  conditions  thereof.  The first  annuity
payment will be made at the beginning of the second month  following the month
in which we approve the  settlement  request.  Annuity  Units will be credited
based on Annuity Unit Values at the end of the Valuation  Period that contains
the tenth day prior to the beginning of said second month.

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

      Information  about the relationship  between the Annuitant's sex and the
amount of annuity payments,  including requirements for gender-neutral annuity
rates in certain states and in connection with certain  employee benefit plans
is set forth under "Gender of Annuitant"  in the  Statement.  See "Contents of
Statement of Additional Information."

OPTION 1 - LIFE  ANNUITY - Annuity  payments  are payable  monthly  during the
lifetime  of the  Annuitant,  ceasing  with the last  payment due prior to the
death of the Annuitant.  It would be possible under this  arrangement  for the
Annuitant or other payee to receive only one annuity  payment if the Annuitant
died prior to the second annuity payment,  since no minimum number of payments
is guaranteed.


                                      23

<PAGE>

OPTION 2 - LIFE  ANNUITY  WITH 120,  180,  OR 240 MONTHLY  PAYMENTS  CERTAIN -
Annuity  payments are payable  monthly  during the  lifetime of an  Annuitant;
provided,   that  if  the  Annuitant  dies  during  the  period  certain,  the
Beneficiary is entitled to receive  monthly  payments for the remainder of the
period certain.

OPTION 3 - JOINT AND LAST SURVIVOR LIFE ANNUITY - Annuity payments are payable
monthly  during the lifetime of the  Annuitant  and another payee and continue
during the lifetime of the  survivor,  ceasing with the last payment  prior to
the death of the survivor.  It is possible under this option for the Annuitant
or other  payee to  receive  only one  annuity  payment if both die before the
second annuity payment, since no minimum number of payments is guaranteed.  If
one of these persons dies before the Annuity  Commencement  Date, the election
of this option is revoked,  the survivor  becomes the sole  Annuitant,  and no
death proceeds are payable by virtue of the death of the other Annuitant.

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

OPTION 5 - PAYMENTS  OF A SPECIFIC  DOLLAR  AMOUNT - The amount due is paid in
equal monthly  installments of a designated  dollar amount (not less than $125
nor more than $200 per annum per $1,000 of the original  amount due) until the
remaining  balance is less than the amount of one  installment.  If the person
receiving these payments dies, the remaining  payments  continue to be made 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, such balance
at the end of the previous month is decreased by the amount of any installment
paid during the month and the result will be  accumulated  at an interest rate
not less than 3.5% compounded  annually.  If the remaining balance at any time
is less than the amount of one installment, such balance will be paid and will
be the final payment under the option.

      Under the fourth  option  there is no  mortality  guarantee  by us, even
though  Variable  Annuity  Payments will be reduced as a result of a charge to
Separate  Account D which is partially  for  mortality  risks.  See "Charge to
Separate Account D."

      A payee  receiving  Variable (but not Fixed) Annuity  Payments under the
fourth  option can elect at any time to commute  (terminate)  such  option and
receive the current  value of the annuity,  which would be based on the values
next  determined  after the Written request for payment is received by us. The
current  value of the  annuity  under  the  fourth  option is the value of all
remaining annuity payments,  assumed to be level,  discounted to present value
at an annual rate of 3.5%.  Other than by election of such a lump-sum  payment
under the fourth option,  an Annuity Payment Option may not be terminated once
annuity payments have commenced.

      Under  federal  tax  regulations,  the  election  of the fourth or fifth
options may be treated in the same manner as a surrender of the total account.
For tax  consequences  of such  treatment,  see "Federal  Income Tax Matters."
Also, in such a case, tax-deferred treatment of subsequent earnings may not be
available.

      ALTERNATIVE  AMOUNT  UNDER FIXED LIFE  ANNUITY  OPTIONS - Each  Contract
provides  that when  Fixed  Annuity  Payments  are to be made under one of the
first three Annuity  Payment  Options  described  above,  the Owner (or if the
Owner has not elected a payment  option,  the  Beneficiary)  may elect monthly
payments  to the  Annuitant  or other  properly-designated  payee equal to the
monthly payment available under similar


                                      24

<PAGE>

circumstances  based on single payment  immediate  fixed annuity rates then in
use by us. The purpose of this  provision is to assure the Annuitant  that, at
retirement,  if the fixed  annuity  purchase  rate then  offered by us for new
single payment  immediate annuity contracts is more favorable than the annuity
rates guaranteed by the Contract,  the Annuitant or other  properly-designated
payee will be given the benefit of the new annuity rates.

      In lieu of monthly  payments,  payments  may be elected on a  quarterly,
semi-annual or annual basis,  in which case the amount of each annuity payment
will be determined 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 Separate  Account D or from the  Divisions to a fixed
Annuity  Payment  Option.  No charge will be assessed  for such  transfer.  No
transfers from a fixed to a variable Annuity Payment Option are permitted.  If
a transfer  would  cause the value that is  attributable  to a Contract 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.
Transfers  will be  effected  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 PRIOR TO THE ANNUITY COMMENCEMENT DATE

      The death proceeds  described below are payable to the Beneficiary under
the Contract if, prior to the Annuity  Commencement Date, any of the following
events  occurs:  (a) the Annuitant  dies and no Contingent  Annuitant has been
named  under a  Non-Qualified  Contract;  (b) the  Annuitant  dies and we also
receive  proof of death of any named  Contingent  Annuitant;  or (c) the Owner
(including  the first to die in the case of joint  Owners) of a  Non-Qualified
Contract  dies,  regardless  of  whether  said  deceased  Owner  was  also the
Annuitant  (however,  if the Beneficiary is the Owner's surviving spouse,  the
Beneficiary  may elect to  continue  the  Contract as  described  in the fifth
paragraph  below).  The death  proceeds,  prior to deduction of any applicable
premium  taxes,  will equal the  greatest  of (1) the sum of all net  purchase
payments  made  (less  any  previously-deducted  premium  taxes  and all prior
partial  withdrawals),  (2) 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  (3)  the  Highest
Anniversary Value prior to the date of death, as defined below.

      The  Highest  Anniversary  Value  prior  to the  date of  death  will be
determined as follows:

            First,  we will calculate the Account Values at the end of each of
            the  past  Contract  Anniversaries  that  occurred  prior  to  the
            deceased's 81st birthday;

            Second, each of the Account Values will be increased by the amount
            of net  purchase  payments  made  since  the end of such  Contract
            Years; and

            Third, the result will be reduced by the amount of any withdrawals
            made since the end of such Contract Years.


                                      25

<PAGE>

      The Highest  Anniversary Value will be an amount equal to the highest of
such values.  The Highest  Anniversary  Value will not be calculated after the
81st birthday.  Net purchase  payments are purchase  payments less  applicable
premium tax.

      We will pay the death  proceeds  to the  Beneficiary  as of the date the
proceeds become payable. Such date is the end of the Valuation Period in which
we receive proof of the Owner's or Annuitant's  death and a Written request in
good order from the Beneficiary as to the manner of payment.

      If the Owner has not already done so, the Beneficiary  may, within sixty
days after the date the death proceeds  become  payable,  elect to receive the
death  proceeds  as a lump  sum or in the form of one of the  Annuity  Payment
Options provided in the Contract. See "Annuity Payment Options." If we receive
no request as to the manner of payment, we will make a lump-sum payment, based
on values determined at that time.

      If the Owner under a  Non-Qualified  Contract  dies prior to the Annuity
Commencement  Date,  the Code  requires  that all  amounts  payable  under the
Contract be  distributed  (a) within five years of the date of death or (b) as
annuity payments beginning within one year of the date of death and continuing
over a period not extending beyond the 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 and, if the  original  Owner was the
Annuitant,  as the new Annuitant.  If the Owner is not a natural person, these
requirements  apply upon the death of the primary Annuitant within the meaning
of the Code.  Failure to  satisfy  these Code  distribution  requirements  may
result in serious adverse tax  consequences.  Under a parallel  section of the
Code, similar  requirements apply to retirement plans in connection with which
Qualified Contracts are issued.

DEATH PROCEEDS AFTER THE ANNUITY COMMENCEMENT DATE

      If the Annuitant dies following the Annuity  Commencement Date, the only
amounts payable to the Beneficiary or other  properly-designated payee are any
continuing  payments  provided for under the Annuity Payment Option  selected.
See "Annuity  Payment  Options."  In such a case,  the payee will have all the
remaining  rights and powers  under a Contract and be subject to all the terms
and  conditions  thereof.  Also, if the Annuitant  dies  following 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,  any  remaining  amounts  payable  under  the terms of the
Annuity  Payment  Option must be  distributed at least as rapidly as under the
method of distribution  then in effect.  If the payee is not a natural person,
this  requirement  applies upon the death of the primary  Annuitant within the
meaning of the Code.  Failure to satisfy  these  requirements  of the Code may
result in serious adverse tax  consequences.  Under a parallel  section of the
Code,  similar  requirements  apply to the retirement plans in connection with
which Qualified Contracts are issued.


                                      26

<PAGE>

PROOF OF DEATH

      We accept the  following  as proof of any  person's  death:  a copy of a
certified  death  certificate;  a copy of 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 we
have no further obligations thereunder.

                          CHARGES UNDER THE CONTRACTS

PREMIUM TAXES

      When applicable, we will deduct an amount to cover premium taxes imposed
by certain  states.  We may deduct such  amount  either at the time the tax is
imposed or later.  Such deduction may be made, in accordance  with  applicable
state law:

(1)   from purchase payment(s) when received; or
(2)   from the Owner's Account Value at the time annuity payments begin; or
(3)   from the amount of any partial withdrawal; or
(4)   from  proceeds  payable upon  termination  of the Contract for any other
      reason,  including  death of the Annuitant or Owner, or surrender of the
      Contract.

      If  premium  tax is paid,  AGL may  reimburse  itself  for such tax when
deduction is being made under items 2, 3, or 4 above calculated 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% and 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 related to
distributing  the  Contracts.  We  believe,  however,  that the amount of such
expenses will exceed the amount of revenues generated by the Surrender Charge.
We will pay such  excess  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 is withdrawn  during the first seven years after it was received.
The  percentage  declines  depending  on how many years have passed  since the
withdrawn  purchase payment was originally  credited to your Account Value, as
follows:

</TABLE>

      Only for the purpose of computing  the  Surrender  Charge,  the earliest
purchase  payments are deemed to be withdrawn first, and before any amounts in
excess of  purchase  payments  are  withdrawn  from your  Account  Value.  The
following  transactions  will be  considered  as  withdrawals  for purposes of
assessing  the  Surrender  Charge:   total  surrender,   partial   withdrawal,
commencement of an Annuity Payment Option, and termination due to insufficient
Account Value.

      Nevertheless,  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,  prior to 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;

      Annuitization  over at least 10 years, or life contingent  annuitization
      where the life expectancy is at least 10 years;

      Within the 30 day window under the One-Time Reinstatement Privilege;

      If the Annuitant  has been  confined to a long-term  care facility or is
      subject to a terminal  illness  (to the extent  that the rider for these
      matters is available in your state),  as set forth under "Long-Term Care
      and Terminal Illness".

      The Surrender Charge also does NOT apply to the surrender of a Contract,
or to the withdrawal of Contract Value (limited to the Variable  Account Value
and the one year  Guarantee  Period) of a Contract,  issued to owners who are:
(1) employees or registered  representatives (or the spouses or minor children
of employees or registered representatives) of any broker-dealer authorized to
sell  the  Contracts,  or (2)  officers,  directors,  or  bona-fide  full-time
employees of AGL or American General  Securities  Incorporated,  the principal
underwriter of the Contracts,  or their  affiliated  companies,  or Van Kampen
American Capital Distributors,  Inc., the distributor of the Contracts, or its
affiliated  companies.  These  waivers of Surrender  Charge are based upon the
Contract Owner's status at the time the Contract was purchased.

      In addition,  the Surrender Charge does NOT apply to 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 (a)


                                      28

<PAGE>

have not previously  been withdrawn and (b) have been credited to the Contract
for at least one year.  If  multiple  withdrawals  are made  during a Contract
Year, the amount  eligible for the free withdrawal will be recalculated at the
time of each  withdrawal.  After the first  Contract Year,  non-automatic  and
automatic withdrawals may be made 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.

      The Surrender  Charge will not apply to any amounts  withdrawn which are
in  excess  of the  amount  permitted  by the 10% free  withdrawal  privilege,
described  above,  if such  amounts are  required to be withdrawn 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 assets are withdrawn from a Contract funding such trust more
rapidly than the 10% free withdrawal privilege would permit. This exception is
subject to our approval.

      A free  withdrawal  pursuant to any of the  foregoing  Surrender  Charge
exceptions is not deemed to be a withdrawal of purchase  payments,  except for
purposes of  computing  the 10% free  withdrawal  described  in the  preceding
paragraph.  A penalty tax may be imposed on  distributions if the recipient is
under age 59 1/2. See "Penalty Tax on Premature Distributions."

TRANSFER CHARGES

      The charges to defray the expense of effecting  transfers  are described
under "Transfer,  Automatic  Rebalancing,  Surrender and Partial Withdrawal of
Owner  Account  Value -  Transfers"  and "Annuity  Period and Annuity  Payment
Options - Transfers." These charges are designed not to yield a profit to us.

ANNUAL CONTRACT FEE

      An Annual Contract Fee of $30 will be deducted from each Owner's Account
Value at the end of each Contract Year prior to the Annuity Commencement Date.
This Fee is for  administrative  expenses  (which do not  include  expenses of
distributing  the  Contracts),  and we do not expect that the revenues we will
derive from this Fee will exceed such expenses.  Unless paid directly, the Fee
will be allocated  among the Guarantee  Periods and Divisions in proportion to
your Account Value in each.  Certain states,  however,  restrict the amount of
the Fee which can be allocated to the  Guarantee  Periods.  The entire Fee for
the year will be deducted from the proceeds of any full surrender.  We reserve
the right to waive the Fee.

CHARGE TO SEPARATE ACCOUNT D

      To offset  other  administrative  expenses  not  covered  by the  Annual
Contract Fee discussed above, and to compensate us for assuming  mortality and
expense  risks  under the  Contracts,  Separate  Account D will  incur a daily
charge at an annualized  rate of 1.40% of the average daily net asset value of
Separate Account D attributable to the Contracts.  Of this amount, .15% is for
administrative  expenses  and 1.25% is for the  assumption  of  mortality  and
expense risks. We do not expect to earn a profit on that portion of the charge


                                      29

<PAGE>

which is for administrative expenses, but we do expect to derive a profit from
the portion which is for the assumption of mortality and expense risks.  There
is no  necessary  relationship  between the amount of  administrative  charges
imposed on a given Contract and the amount of expenses  actually  attributable
to that Contract.

      In  assuming  the  mortality  risk,  we are subject to the risk that our
actuarial  estimate of mortality rates may prove erroneous and that Annuitants
will live  longer  than  expected,  or that more  Owners  or  Annuitants  than
expected will die at a time when the death benefit  guaranteed by us is higher
than the net surrender value of their interests in the Contracts.  In assuming
the  expense  risk,  we are  subject  to the risk that the  revenues  from the
expense  charges under the Contracts  (which  charges are guaranteed not to be
increased) will not cover our expense of administering the Contracts.

MISCELLANEOUS

      Charges  and  expenses  are paid out of the  assets of each  Series,  as
described in the prospectus  relating to that Series.  We reserve the right to
impose  charges or establish  reserves for any federal or local taxes incurred
or that may be  incurred  by us,  and that may be deemed  attributable  to the
Contracts.

SYSTEMATIC WITHDRAWAL PLAN

      Automatic  partial  withdrawals,  with minimum  payments of $100, may be
made at periodic  intervals  through a systematic  withdrawal  program and the
Contract  Owner may choose  from  payment  schedules  of  monthly,  quarterly,
semi-annually,  or  annually,  and  may  start,  stop,  increase  or  decrease
payments.  Withdrawals  may start as early as 30 days  after the issue date of
the  Contract  and may be taken  from the Fixed  Account or any  Division,  as
specified by the Owner.  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,  the Owner may elect to reinvest
all of the proceeds that were  previously  liquidated from the Contract within
the past 30 days and have the Surrender Charge and any Annual Contract Fee not
then due credited  back to the  Contract.  The funds will be reinvested at the
value next  following  the date of receipt of the  reinstated  Account  Value.
Unless you request  otherwise,  the reinstated Account Value will be allocated
among the Divisions and Guarantee Periods in the same proportions as the prior
surrender. You may use this privilege only once.

REDUCTION IN SURRENDER CHARGES OR ADMINISTRATIVE CHARGES

      We may reduce the Surrender  Charges or  administrative  charges imposed
under certain Qualified Contracts in connection with employer-sponsored plans.
Any such reductions will reflect differences in costs or services (due to such
factors 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)  and will not be
unfairly discriminatory as to any person.

                      LONG-TERM CARE AND TERMINAL ILLNESS

      THE RIDER DESCRIBED BELOW IS NOT AVAILABLE IN ALL STATES, AND YOU SHOULD
THEREFORE  CONSULT YOUR SALES  REPRESENTATIVE OR OUR HOME OFFICE AS TO WHETHER
IT WILL APPLY TO YOU.  THERE IS NO  SEPARATE  CHARGE FOR THIS  RIDER.LONG-TERM
CARE

      Pursuant to 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  for 30 days or more  (or  within  30 days  after
discharge) in a hospital or state-licensed  in-patient  nursing  facility.  We
must receive Written proof of such confinement that is satisfactory to us.

TERMINAL ILLNESS

      The rider also provides that no Surrender Charge will apply to a partial
withdrawal  or total  surrender  if we have  received  a  physician's  Written
certification  that the Annuitant is  considered to be terminally  ill and not
expected to live more than  twelve  months and have  waived or  exercised  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  and are not entitled to
share in any dividends, profits or surplus of AGL.

OWNERS, ANNUITANTS, AND BENEFICIARIES; ASSIGNMENTS

      The Owner of a Contract  will be the same as the  Annuitant,  unless the
purchaser  designates a different  Owner when applying to purchase a Contract.
In the case of joint  ownership,  both Owners must join in the exercise of any
rights or  privileges  under the Contract.  The  Annuitant and any  Contingent
Annuitant  are  designated  in the  application  for a  Contract  and  may not
thereafter be changed.

      The  Beneficiary  and any Contingent  Beneficiary  are  designated  when
applying to purchase a Contract.  A Beneficiary or Contingent  Beneficiary may
be changed by the Owner  prior to the  Annuity  Commencement  Date,  while the
Annuitant is still alive, and by the payee following the Annuity  Commencement
Date.  Any  designation  of a new  Beneficiary  or Contingent  Beneficiary  is
effective as of the date it is signed but will not affect any payments we make
or action we take  before  receiving  the  Written  request.  We also need the
Written consent of any irrevocably-named Beneficiary or Contingent Beneficiary
before making a change. Under certain retirement programs, spousal consent may
be  required  to name a  Beneficiary  other  than the  spouse  or to  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 no named Beneficiary or Contingent  Beneficiary is living at the time
any payment is to be made, the Owner will be the Beneficiary,  or if the Owner
is not then living, the Owner's estate will be the Beneficiary.

      Rights under a Qualified Contract may be assigned only in certain narrow
circumstances  referred to therein.  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.  A  change  in
ownership rights


                                      31

<PAGE>

must be made in Writing and a copy must be sent to our Home Office. The change
will be  effective  on the date it was  made,  although  we are not bound by a
change until the date we record it. The rights under a Contract are 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  persons  receiving  payments  following  the
Annuity Commencement Date), at their last known address of record, any reports
and  communications  required  by  applicable  law or  regulation.  You should
therefore give us prompt written notice of any address change.

RIGHTS RESERVED BY US

      Upon  notice to the Owner,  a  Contract  may be  modified  by us, to the
extent  necessary  in  order to (1)  operate  Separate  Account  D in any form
permitted  under  the 1940 Act or in any  other  form  permitted  by law;  (2)
transfer  any assets in any  Division to another  Division,  or to one or more
separate accounts,  or the Fixed Account; (3) add, combine or remove Divisions
in Separate  Account D, or combine the Separate  Account with another separate
account;  (4) add,  restrict or remove Guarantee Periods of the Fixed Account;
(5) make any new Division  available to you on a basis to be determined by us;
(6)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;  (7) make any changes  required by the Code or by any other
applicable law, regulation or interpretation in order to continue treatment of
the Contract as an annuity; (8) commence deducting premium taxes or adjust the
amount of premium taxes deducted in accordance with  applicable  state law; or
(9) make any changes  required  to comply  with the rules of any Series.  When
required by law, we will obtain your  approval of changes and the  approval of
any appropriate regulatory authority.

PAYMENT AND DEFERMENT

      Amounts  surrendered  or withdrawn from a Contract will normally be paid
within seven  calendar days after the end of the Valuation  Period in which we
receive the Written surrender or withdrawal request in good order. In the case
of payment of death proceeds, if we do not receive a Written request as to the
manner of payment within 60 days after the death proceeds become payable,  any
death  benefit  proceeds  will be paid as a lump sum,  normally  within  seven
calendar days after the end of the Valuation Period that contains the last day
of said 60 day period.  We reserve  the right,  however,  to defer  payment or
transfers of amounts 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  and
annuity  payment  amounts  or death  benefit  amounts  of any  portion  of the
Variable Account Value if (a) the New York Stock Exchange is closed other than
customary  weekend  and  holiday  closings,  or  trading on the New York Stock
Exchange is restricted; (b) an emergency exists, as a result of which disposal
of  securities  is  not  reasonably   practicable  or  it  is  not  reasonably
practicable  to  fairly  determine  the  Variable  Account  Value;  or (c) the
Securities  and  Exchange  Commission  by  order  permits  the  delay  for the
protection  of Owners.  Transfers and  allocations  of Account Value among the
Divisions   and  the  Fixed   Account  may  also  be  postponed   under  these
circumstances.

                          FEDERAL INCOME TAX MATTERS
GENERAL

      It is  not  possible  to  comment  on  all of  the  federal  income  tax
consequences associated with the Contracts.  Federal income tax law is complex
and its  application  to a  particular  person  may  vary  according  to facts
peculiar to such person. Consequently,  this discussion is not intended as tax
advice,  and you should consult with a competent tax adviser before purchasing
a Contract.

      The  discussion  is based on the law,  regulations  and  interpretations
existing  on the date of this  Prospectus.  These  authorities,  however,  are
subject to change by Congress, the Treasury Department and judicial decisions.

      The discussion does not address state or local tax, estate and gift tax,
or social security 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 therefore  "Non-Qualified"  may not deduct from
their gross income the amount of purchase payments made.

      TAX DEFERRAL PRIOR TO ANNUITY  COMMENCEMENT DATE. Owners who are natural
persons are not taxed  currently on increases in their Account Value resulting
from  interest  earned in the Fixed  Account  or, if  certain  diversification
requirements  are met, the investment  experience of Separate  Account D. This
treatment  applies to Separate Account D only if it invests in Series that are
"adequately  diversified" in accordance with Treasury Department  regulations.
Although we do not control the Series,  the investment  advisers to the Series
have  undertaken 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 that has not previously been taxed.
Income means the excess of the Account  Value over the Owner's  investment  in
the Contract (discussed below).

      Current  regulations do not provide guidance as to any  circumstances in
which   control  over   allocation  of  values  among   different   investment
alternatives  may cause  Owners or persons  receiving  annuity  payments to be
treated  as the  owners of  Separate  Account D assets  for tax  purposes.  We
reserve the right to amend the  Contracts  in any way  necessary  to avoid any
such  result.  The  Treasury  Department  has  stated  that  it may  establish
standards in this regard through  regulations  or rulings.  Such standards may
apply only prospectively, although retroactive application is possible if such
standards are considered not to embody 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 exist for, among other things, Owners
that are not  natural  persons  but that hold the  Contract  as an agent for a
natural person.

      TAXATION OF ANNUITY  PAYMENTS.  Each annuity payment  received after the
Annuity Commencement Date is excludible from gross income in part. In the case
of Fixed Annuity Payments, the excludible portion is determined 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 amount paid is multiplied by the ratio
of the investment in the Contract to 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


                                      33

<PAGE>

payments cease on account of the death of the Annuitant  before the investment
in the Contract has been fully recovered, the payee is allowed a deduction for
the unrecovered amount. If the payee is the Annuitant,  the deduction is taken
on the final tax return.  If the payee is a Beneficiary,  that Beneficiary may
recover 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 a
Contract is surrendered in its entirety,  any amount received in excess of the
investment in the Contract is includible in income,  and any remaining  amount
received is excludible from income.  All annuity contracts issued by us to the
same Owner  during any  calendar  year are to be  aggregated  for  purposes of
determining the amount of any distribution that is includible in gross income.

      PENALTY  TAX ON  PREMATURE  DISTRIBUTIONS.  A penalty  tax is imposed on
distributions  under a  Contract  equal  to 10% of the  amount  includible  in
income. The penalty tax will not apply,  however, to (1) distributions made on
or after the recipient attains age 59 1/2, (2) distributions on account of the
recipient's becoming disabled, (3) distributions that are made after the death
of the Owner  prior to the  Annuity  Commencement  Date or 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),  and
(4)  distributions  that are part of a series of substantially  equal periodic
payments made over the life (or life expectancy) of the Annuitant or the joint
life (or  joint  life  expectancies)  of the  Annuitant  and the  Beneficiary.
Premature  distributions  may  result,  for  example,  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  clause (3) 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 with respect to 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  $25,000  may fully  deduct  their IRA  purchase  payments.  Those who have
adjusted gross income in excess of $35,000 will not be able to deduct purchase
payments, and for those with adjusted gross income between $25,000 and $35,000
the deduction is phased out based on the amount of income.  Beginning in 1998,
the  income  range  over  which the  otherwise  deductible  portion  of an IRA
purchase  payment  will be phased out for single  persons  will  increase,  as
follows:  1998--$30,000 to $40,000; 1999--$31,000 to $41,000; 2000--$32,000 to
$42,000;  2001--$33,000 to $43,000; 2002--$34,000 to $44,000; 2003--$40,000 to
$50,000;  2004--$45,000  to  $55,000;  and  2005  and  thereafter--$50,000  to
$60,000.
    


                                      34

<PAGE>

   
      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  $40,000 and $50,000,  and in the
case of married  individuals  filing  separately,  with adjusted  gross income
between $0 and  $10,000.  Beginning  in 1998,  the income range over which the
otherwise deductible portion of an IRA purchase payment will be phased out for
married  individuals  filing  joint tax  returns  will  increase  as  follows:
1998--$50,000 to $60,000;  1999--$51,000 to $61,000; 2000--$52,000 to $62,000;
2001--$53,000 to $63,000; 2002-- $54,000 to $64,000; 2003--$60,000 to $70,000;
2004--$65,000 to $75,000;  2005--$70,000 to $80,000; 2006--$75,000 to $85,000;
and 2007 and thereafter--$80,000 to $100,000.

      Also beginning in 1998, 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 such an individual,  the
income range over which the  otherwise  deductible  portion of an IRA purchase
payment will be phased out is $150,000 to $160,000.

      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 included in income.  A 10% penalty tax is imposed on
the amount includible in gross income from distributions that occur before the
Annuitant  attains  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 over
the life (or life  expectancy)  of the  Annuitant or the joint lives (or joint
life  expectancies) of the Annuitant and the  Beneficiary.  Beginning in 1998,
these  exceptions  also include  distributions  for qualified  first-time home
purchases for the individual, a spouse, children,  grandchildren, or ancestor,
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  specified by the Code must commence by April
1 of the calendar  year  following  the calendar  year in which the  Annuitant
attains age 70 1/2. 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 the imposition of a penalty tax of
50% of the  amount by which the  minimum  distribution  required  exceeds  the
actual distribution.

      TAX FREE  ROLLOVERS.  Amounts may be transferred in a tax-free  rollover
from a  tax-qualified  plan to an IRA  (and  from one IRA to  another  IRA) if
certain  conditions  are met. All taxable  distributions  ("eligible  rollover
distributions")  from tax qualified  plans are eligible to be rolled over 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) of the Code.

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

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 limitation is phased out for adjusted
    


                                      35

<PAGE>

   
gross income  between  $95,000 and  $110,000 in the case of single  taxpayers,
between  $150,000 and $160,000 in the case of married  taxpayers  filing joint
returns,  and between $0 and $15,000 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.

      Qualified  distributions  from  Roth  IRAs  are  entirely  tax  free.  A
qualified  distribution requires that the individual has held the Roth IRA for
at least five years and, in  addition,  that 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,  subject to $10,000
lifetime  maximum,  for  the  individual,  a  spouse,  child,  grandchild,  or
ancestor.

      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.   For  rollovers  in  1998,  the
individual  may pay that tax  ratably  in 1998 and over the  succeeding  three
years.  There  are no  similar  limitations  on  rollovers  from a Roth IRA to
another Roth IRA.
    

SIMPLIFIED EMPLOYEE PENSION PLANS

      Employees  and 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.  However,  total employer contributions are limited to
15% of an employee's compensation or $30,000, whichever is less.

SIMPLE RETIREMENT ACCOUNTS

      Employees  and  employers  may  establish  an IRA plan known as a simple
retirement account ("SRA"), if certain requirements are met. Under an SRA, the
employer contributes elective employee compensation  deferrals up to a maximum
of $6,000 a year. The employer must, in general,  make a fully vested matching
contribution for employee deferrals up to 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.
Such  purchase  payments  are also  excluded  from the  current  income of the
employee.

      DISTRIBUTIONS PRIOR TO THE ANNUITY COMMENCEMENT DATE. To the extent that
purchase payments are includible in an employee's  taxable income,  they (less
any amounts  previously  received that were not  includible in the  employee's
taxable  income)  represent his or her  "investment in the Contract."  Amounts
received prior to 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  or 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
in the case of certain lump-sum


                                      36

<PAGE>

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's  attaining age 59 1/2 and
that are not made on account of death or disability,  with certain exceptions.
These  exceptions  include  distributions  that are (1)  part of a  series  of
substantially  equal periodic payments  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,  (2) made after the employee's separation from service on account
of early  retirement after attaining age 55, or (3) made to an alternate payee
pursuant to a qualified domestic relations order.

      ANNUITY PAYMENTS. A portion of annuity payments received under Contracts
in connection with 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," except that the number of expected
payments is determined under a provision in the Code. Distributions of minimum
amounts  specified  by the  Code  generally  must  commence  by April 1 of the
calendar year following the calendar year in which the employee attains age 70
1/2 or retires,  if later.  Failure to comply  with the  minimum  distribution
rules will result in the  imposition  of 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.

      These types of programs allow individuals to defer receipt of up to 100%
of compensation  that would otherwise be includible in income and therefore to
defer the payment of federal income taxes on such amounts, as well as earnings
thereon. Purchase payments made by the employer,  however, are not immediately
deductible  by the  employer,  and the  employer  is  currently  taxed  on any
increase in Account Value.

      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.

      TAXATION OF  DISTRIBUTIONS.  Amounts  received by an  individual  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.

EXCESS DISTRIBUTIONS - 15% TAX

      Certain  persons,  particularly  those who  participate in more than one
tax-qualified  retirement  plan, may be subject to an additional tax of 15% on
certain excess aggregate  distributions  from those plans. In general,  excess
distributions are taxable  distributions for all tax qualified plans in excess
of a  specified  annual  limit  for  payments  made in the form of an  annuity
(currently   $160,000)   or  five   times  the  annual   limit  for   lump-sum
distributions.

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. The payee may, however,
elect to have no income tax  withheld by  submitting a  withholding  exemption
certificate to us.

      In some cases, if you own more than one Qualified annuity contract, such
contracts may be aggregated  for purposes of  determining  whether the federal
tax law requirement for minimum  distributions after age 70 1/2, or retirement
in appropriate  circumstances,  has been satisfied. If, under this aggregation
procedure,  you are  relying on  distributions  pursuant  to  another  annuity
contract  to satisfy the minimum  distribution  requirement  under a Qualified
Contract issued by us, 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 SEPARATE ACCOUNT D

      AGL is taxed as a life insurance  company under the Code. The operations
of  Separate  Account  D 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  Separate  Account D  (including  realized  and
unrealized  capital  gains) with  respect to the  Contracts.  AGL reserves the
right to allocate to the Contracts  any federal,  state or other tax liability
that may result in the future from  maintenance  of Separate  Account D 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  which are also  passed  through.  These  credits may
provide a benefit to AGL.

                           DISTRIBUTION ARRANGEMENTS

      The  Contracts  will be sold by  individuals  who,  in addition to being
licensed by state insurance authorities to sell the Contracts of AGL, are also
registered   representatives  of  American  General  Securities   Incorporated
("AGSI"),   the  principal   underwriter  of  the  Contracts,   or  registered
representatives  of Van Kampen American  Capital  Distributors,  Inc. or other
broker-dealer  firms or  representatives  of other  firms that are exempt from
broker-dealer regulation. AGSI, Van Kampen American Capital Distributors, Inc.
and any such other  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 the same as that of our Home Office.  The interests under
the Contracts are offered on a continuous  basis. AGSI and Van Kampen American
Capital Distributors,  Inc. have entered into certain revenue and cost-sharing
arrangements in connection with the marketing of the Contracts.

      AGL compensates Van Kampen American  Capital  Distributors,  Inc. ("VKAC
Distributors") and other  broker-dealers  that sell the Contracts according to
one or more  compensation  schedules.  The schedules  provide for  commissions
ranging from 4.75% up to 6% of first year purchase  payments received pursuant
to the Contracts. In addition, depending on the schedule selected, AGL may pay
continuing "trail" commissions ranging from 0.25% to 0.50% of Contract Account
Value.  AGL  also has  agreed  to pay VKAC  Distributors  for its  promotional
activities  such as the  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 as well as related  marketing  support and related special  promotional
campaigns. These distribution expenses do not result in any additional charges
under  the  Contracts  that  are  not  described   under  "Charges  under  the
Contracts."
