                                                                     May 1, 1998
    

              GROUP UNALLOCATED DEFERRED VARIABLE ANNUITY CONTRACT
                                   Offered by
                 The Guardian Insurance & Annuity Company, Inc.

      The Group Unallocated Deferred Variable Annuity Contract ("Contract")
described in this Prospectus is issued by The Guardian Insurance & Annuity
Company, Inc. ("GIAC"), and is designed to provide annuity benefits under group
pension and profit sharing plans entitled to favorable federal income tax
treatment under the Internal Revenue Code of 1986 ("Code"), as amended
("qualified retirement plans"), and certain other retirement plans which are not
entitled to such federal income tax benefits ("non-qualified retirement plans")
(collectively referred to as the "Plans"). Generally, for federal income tax
purposes, earnings credited to Contracts issued in connection with non-qualified
retirement plans will be taxed on an annual basis.

   
      The Contract described in this Prospectus is a Flexible Premium Payment
Contract. A minimum initial premium payment of $5,000 is required and the
minimum for subsequent premium payments is $500. The premium payment less any
state or local premium taxes constitute the Net Premium Payment. Net Premium
Payments for the Contract may be allocated in up to six of the allocation
options underlying the Contract. Contract values will accumulate on either a
variable or fixed basis, depending on the options selected. These options
currently consist of the following: (1) shares of The Guardian Stock Fund, Inc.,
The Guardian Bond Fund, Inc., The Guardian Cash Fund, Inc., The Guardian Small
Cap Stock Fund, Baillie Gifford International Fund, Baillie Gifford
Emerging Markets Fund, Value Line Strategic Asset Management Trust, Value
Line Centurion Fund, Inc., Gabelli Capital Asset Fund and MFS Growth With Income
Series (collectively referred to as the "Funds"); and (2) allocations to the
Fixed-Rate Option. Net Premium Payments and Contract values allocated to any of
the Funds will vary in accordance with the investment performance of such Funds.
Net Premium Payments and Contract values allocated to the Fixed-Rate Option will
accumulate on a fixed basis. The Contractowner bears the investment risk of
growth or loss under the Contract, except to the extent that amounts are
allocated to the Fixed-Rate Option.

      This Prospectus sets forth the information that a prospective
Contractowner should know before investing. A Statement of Additional
Information concerning the Contracts and The Guardian Separate Account D (The
"Separate Account") is available for free by writing to GIAC at its Customer

recipient of annuity payments). The Annuitant may also be referred to as the
"Plan Participant" or, simply, the "Participant."

of the Contract.

Contractowner: The entity designated as the owner in the Contract.

Fixed-Rate Option: A deposit option to which the Contractowner may allocate Net

of GIAC. GIAC guarantees that the amount deposited will not decline in value and
that interest will be added at a guaranteed rate declared periodically in
advance.

   
Funds: The ten diversified open-end management investment companies or series
thereof underlying the Contract. Contractowners may allocate Net Premium
Payments and Accumulation Values to the Funds through the corresponding
Investment Divisions of the Separate Account. The Funds are: The Guardian Stock

reflect the investment experience of the Variable Investment Options.

Variable Investment Options: The Funds constitute the Variable Investment
Options (as distinguished from the Fixed-Rate Option) available under the
Contract for allocations of Net Premium Payments, Accumulation Values and
Annuity Unit values.

                             SUMMARY OF THE CONTRACT

      The Contract described in this Prospectus is designed to provide annuity
benefits for the lives of the Participants (Annuitants) pursuant to the Annuity
Payout Option selected and the Plan under which the Contract has been issued.
The Contract provides several underlying allocation options among which the
Contractowner may select to pursue its investment objectives. If an Annuity
Payout Option is selected that provides for monthly payments during the lifetime
of the Annuitant, GIAC promises to make Annuity Payments continuously for the
life of each Annuitant under the Contract even if such Annuitant outlives the
life expectancy used in computing his or her Annuity. While GIAC is obligated to
make Annuity Payments regardless of the longevity of the Annuitants under the
Plan, the amount of variable Annuity Payments is not guaranteed. With respect to
amounts attributable to the Variable Investment Options, no assurance can be
given that the value of the Contract, or the aggregate value of the Accumulation
Units used to purchase Annuities on behalf of Plan Participants under the
Contract, will equal or exceed the payments allocated to such Variable
Investment Options.

   
      GIAC provides for variable and fixed accumulations and benefits under the
Contract by crediting the Net Premium Payments to as many as six of the Variable
Investment Options or five Variable Investment Options and the Fixed-Rate
Option, as selected by the Contractowner. (See "Descriptions of the Variable
Investment Options," page 13, and "Description of the Fixed-Rate Option," page
16.) To the extent the Contractowner has allocated values to one or more of the
Variable Investment Options, the Contract value and the amount accumulated to
purchase Annuities on behalf of Plan Participants will depend upon the
investment performance of the Variable Investment Options. Amounts allocated to
the Fixed-Rate Option will accrue interest at a rate not less than the
guaranteed minimum interest rate specified in the Contract. (See "Accumulation
Period," page 19, and "Annuity Period," page 20.) The investment risk under the
Contract is borne by the Contractowner during the Accumulation Period except to
the extent that Accumulation Values are allocated to the Fixed-Rate Option where
the investment risk is borne by GIAC. The investment risk of gain or loss under
the Contract is borne by the Annuitant during the Annuity Period if values are
then allocated to the Variable Investment Options.

      Contract values may be transferred among the Investment Divisions of the
Separate Account by the Contractowner with respect to the Accumulation Value
under the Contract and by each Annuitant with respect to amounts held under a
Certificate, subject to certain terms and conditions and in accordance with the
Plan. Certain restrictions apply to transfers to or from the Fixed-Rate Option.
(See "Transfers of Contract Values," page 22.)

      If permitted by the Plan, a Participant may elect to have Annuity Payments
made under any one of the variable and/or fixed Annuity Payout Options specified
in the Contract. If the Plan does not permit the Participant to select an
Annuity Payout Option, Annuity Payments will be made pursuant to the option
known as "Life Annuity with 10-year Guaranteed Period." (See "Annuity Payout
Options," page 20.)
    

      The Contract contains the following additional features which are
described in more detail in this Prospectus:

   
            (1) No sales charges are deducted from Contract payments. However,
      if part or all of the Accumulation Value is withdrawn during certain
      periods of time following the payment of premiums, GIAC will deduct from
      such Accumulation Value a contingent deferred sales charge of 6.0%. A
      penalty tax may be imposed on all or a portion of such withdrawals. (See
      "Charges and Deductions," page 18, "Surrenders and Partial Withdrawals,"
      page 23, and "Federal Tax Matters," page 28.)

            (2) Charges for the assumption by GIAC of the mortality and expense
      risks under the Contract, the administrative expenses incurred by GIAC and
      state premium taxes, if any, are deducted from the Accumulation Value.
      (See "Charges and Deductions," page 18.) In addition, the Funds impose
      certain
    


                                       5
<PAGE>

      charges against their respective assets. (See the applicable Fund
      prospectus for information about these charges.)

   
            (3) In certain states, the Contractowner may cancel a Contract no
      later than ten (10) days after receiving it by returning the Contract
      along with written notice of cancellation to GIAC. Longer periods may
      apply in some states. (See "Right to Cancel the Contract," page 34.)

      Certain federal income tax advantages are currently available for a
Contract issued in connection with a retirement Plan which qualifies under
Section 401 of the Code. The Contract is also available in connection with
deferred compensation plans of state and municipal governments and of tax-exempt
employers under Section 457 of the Code. The Contract is offered in connection
with other deferred compensation arrangements under which the Contract may not
qualify as an annuity for Federal income tax purposes. (See "Federal Tax
Matters," page 28.)

      first withdrawal in a Contract year or 10% of the total premium paid under
      the Contract in the last 84 months immediately preceding the date of
      withdrawal, whichever is greater, can be withdrawn annually without
      charge. The maximum amount of this charge during the 84 months immediately
      preceding the date of withdrawal will not exceed 6% of the total of
      payments made during such period.

   
**    These percentages reflect the actual fees and expenses incurred by each
      Fund during the year ended December 31, 1997, except that the percentages
      for The Small Cap Stock Fund are annualized, since the Fund commenced
      operations on April 2, 1997. The percentages for Value Line Centurion Fund
      and Value Line Strategic Asset Management Trust reflect (as part of "Other
      Expenses" and "Total Fund Operating Expenses") the effects of expense
      reimbursement arrangements pursuant to which each of these Funds
      reimburses GIAC for certain administrative and shareholder servicing
      expenses incurred by GIAC on their behalf.

+     The Adviser of MFS Growth With Income Series has agreed to bear expenses
      for the Series, subject to reimbursement by the Series, such that the
      Series' "Other Expenses" shall not exceed 0.25% of the average daily net
      assets of the Series during the current fiscal year. Otherwise, "Other
      Expenses" and "Total Operating Expenses" for the Series would be .35% and
      1.10%, respectively.

</TABLE>

      This expense comparison assumes that the expenses reported in the expense
table on the foregoing page will be the expenses incurred during the periods
shown above. This comparison is not a representation of past or future expenses.
Actual expenses may be higher or lower than those shown. The effect of the
annual contract fee was calculated by: (1) dividing the total amount of such
fees for the year ended December 31, 1997 by the total average net assets for
such year; (2) adding this percentage to annual expenses; and (3) calculating
the dollar amounts. Premium taxes ranging from approximately 0.50% to 3.5% are
currently imposed by certain states, counties and municipalities on premium
payments made under the Contracts. When applicable, such taxes reduce the amount
of each premium payment available for allocation under the Contracts. See
"Charges and Deductions -- Premium Taxes."

                  DESCRIPTIONS OF GIAC AND THE SEPARATE ACCOUNT

GIAC

   
      The Guardian Insurance & Annuity Company, Inc. ("GIAC") is a stock life
insurance company incorporated in the State of Delaware in 1970. GIAC is the
issuer of the Contract offered under this Prospectus. GIAC is licensed to
conduct an insurance business in all 50 states and the District of Columbia and
had total assets (statutory basis) of over $7.9 billion as of December 31, 1997.
GIAC's Executive Office is located at 201 Park Avenue South, New York, New York
10003. The address of GIAC's Customer Service Office for these Contracts is P.O.
Box 26210, Lehigh Valley, Pennsylvania 18002.

      GIAC is wholly owned by The Guardian Life Insurance Company of America
("Guardian Life"), a mutual life insurance company organized in the State of New
York in 1860. As of December 31, 1997, Guardian Life had total assets (statutory
basis) in excess of $14.0 billion. Guardian Life is not the issuer of the
Contracts offered under this Prospectus and does not guarantee the benefits
provided therein.
    

      GIAC's statutory basis financial statements appear in the Statement of
Additional Information.

The Separate Account

      GIAC established the Separate Account in August 1989. The Separate Account
is registered as a unit investment trust under the Investment Company Act of
1940, as amended (the "1940 Act"), and meets the definition of "separate
account" under the Federal securities laws. The Separate Account receives and
invests payments from Contractowners and owners of certain individual deferred
variable annuity contracts issued by GIAC. In addition, the Separate Account may
receive and invest payments for other variable annuity contracts offered by
GIAC.

   
      There are ten Investment Divisions (which correspond to the ten Funds)
available for allocations of Net Premium Payments and Accumulation Values under
the Contracts. Each Investment Division invests in a specific underlying Fund
and thus reflects that Fund's investment performance. Each such Investment
Division is available for allocations under tax qualified or non-tax qualified
Plans. GIAC is the record owner of all of the Fund shares held by each
Investment Division but passes through the voting rights in such shares. (See
"Voting Rights.")
    

    Each Investment Division is administered and accounted for as part of the
general business of GIAC. Under Delaware law, the income and capital gains or
capital losses of each Investment Division are credited to or charged against
the assets held in that Division in accordance with the terms of each Contract,
without regard to other income, capital gains or capital losses of the other
Investment Divisions. The obligations arising under the Contracts are
obligations of GIAC. Delaware insurance law provides that the assets of the
Separate Account are not chargeable with liabilities arising out of any other
business GIAC may conduct. (See "Federal Tax Matters.")

      Assets of the Separate Account attributable to a Contract are invested in
shares of up to six of the Funds as selected by the Contractowner or Annuitant.
Selecting the Fixed-Rate Option reduces the number of Funds which may be
selected for allocation of Net Premium Payments and Accumulation Values. No
sales charges are assessed against premium payments invested in the Funds under
the Contract. Transfers among the Investment Divisions may currently be effected
without fee, penalty or other charge by notifying GIAC's Customer Service Office
in writing or by telephone. (See "Transfers of Contract Values.")

      All dividends and capital gains distributions received from a Fund are
reinvested in such Fund's shares at net asset value and retained as assets of
the Separate Account through allocation to the applicable 


                                       11
<PAGE>

Investment Division. Fund shares will be redeemed by GIAC at their net asset
value to the extent necessary to purchase Annuities or to make other payments
under the Contract.

      GIAC retains the right, subject to applicable law, to (1) deregister the
Separate Account under the 1940 Act; (2) operate the Separate Account as a
management investment company or any other form permitted by law; (3) combine
any two or more separate accounts or Investment Divisions; (4) transfer the
assets of the Separate Account to another separate account; and (5) modify the
Contracts as necessary to preserve the favorable tax treatment accorded to them
under the Code, including modifications designed to prevent the Contractowner
from being considered the owner of the assets of the Separate Account or the
Fixed-Rate Option and, consequently, to be subject to taxation.

                 DESCRIPTIONS OF THE VARIABLE INVESTMENT OPTIONS
The Funds

      Each Fund has a different investment objective which it tries to achieve
by following specified investment policies. The objective and policies of each
Fund will affect its potential returns and its risks. There is no guarantee that
a Fund will achieve its investment objective. The following chart states the
investment objective and lists typical portfolio investments of each Fund
currently available through the Separate Account.

      Each of the Funds is an open-end diversified management investment company
or series thereof, and is registered with the SEC under the 1940 Act. Such
registration does not involve any supervision by the SEC of the investment
management or policies of the Funds. The Funds do not impose a sales charge or
"load" for buying and selling their shares, so GIAC buys and sells shares at net
asset value in response to Contractowner-requested and other Contract
transactions.

      All of the Funds are also available under other variable annuity contracts
funded by the Separate Account. Certain of the Funds are available under other
separate accounts supporting certain GIAC variable annuity contracts and
variable life insurance policies. Although GIAC does not anticipate any inherent
difficulties in offering these Funds to more than one separate account, it is
possible that certain conflicts of interest may arise in connection with the use
of the same Funds under both variable life insurance policies and variable
annuity contracts. While each Fund's Board of Directors intends to monitor
events in order to identify and, if deemed necessary, act upon any material
irreconcilable conflicts that may possibly arise, GIAC may also take action to
protect Contractowners. See the accompanying prospectuses for the Funds for more
information regarding such possible conflicts of interest.

      GIAC retains the right, subject to any applicable law, to make additions
to, deletions from, or substitutions for, the Fund shares held by any Investment
Division. GIAC reserves the right to eliminate the shares of any of the Funds
and to substitute shares of another Fund, or of another registered open-end
management investment company or series thereof or other appropriate investment
vehicle, if: (1) the shares of the Fund are no longer available for investment;
(2) in GIAC's view it has become inappropriate to continue investing in the
Fund's shares. To the extent required by the 1940 Act, substitutions of shares
attributable to a Contractowner's interest in an Investment Division will not be
made until the Contractowner has been notified of the change.

      A more detailed description of the investment objectives, policies,
charges, and expenses of the Funds may be found in the accompanying prospectuses
for the Funds. Read the prospectuses carefully before investing.

The Funds' Investment Advisers

   
      The Guardian Stock Fund, The Guardian Bond Fund, The Guardian Cash Fund
and The Guardian Small Cap Stock Fund (the "Small Cap Fund") are advised by
Guardian Investor Services ("GISC"), 201 Park Avenue South, New York, New York
10003. GISC is registered as an investment adviser under the Investment Advisers
Act of 1940 (the "Advisers Act"). GISC is wholly owned by GIAC. Each of these
Funds, except the Small Cap Fund, pays GISC an investment advisory fee at an
annual rate of 0.50% of the Fund's average daily net assets for the services and
facilities GISC provides to the Fund. The Small Cap Fund pays GISC an investment
advisory fee at an annual rate of 0.75% of the Fund's average daily net assets.
GISC also serves as the manager of Gabelli Capital Asset Fund and as the
investment adviser of eight of the ten series comprising The Park Avenue
Portfolio, a family of mutual funds.

      The Baillie Gifford International Fund (the "International Fund") and
Baillie Gifford Emerging Markets Fund (the "Emerging Markets Fund") are advised
by Guardian Baillie Gifford Limited ("GBG"), 1 Rutland Court, Edinburgh, EH3
8EY, Scotland. GBG is registered as an investment adviser under the Advisers Act
and is a member of Great Britain's Investment Management Regulatory Organization
Limited ("IMRO"). GBG was incorporated in Scotland in November 1990 and is
wholly owned by GIAC (51%) and Baillie Gifford Overseas Limited ("BG Overseas")
(49%). GBG also serves as the investment adviser of two of the ten series
comprising The Park Avenue Portfolio. GBG receives an investment advisory fee at
an annual rate of 0.80% of the average daily net assets of the International
Fund and 1.00% of the average daily net assets of the Emerging Markets Fund for
the services and facilities GBG provides to the Funds.

                      DESCRIPTION OF THE FIXED-RATE OPTION

      That portion of each Contract relating to the Fixed-Rate Option is not
registered under the Securities Act of 1933 ("1933 Act") and the Fixed-Rate
Option is not registered as an investment company under the 1940 Act.
Accordingly, neither the Fixed-Rate Option nor any interests therein are subject
to the provisions or restrictions of the 1933 Act or the 1940 Act. However, the
following disclosure about the Fixed-Rate Option may be subject to certain
generally applicable provisions of the federal securities laws regarding the
accuracy and completeness of statements not in prospectuses. The Fixed-Rate
Option may not be available for allocation in all states in which the Contract
is available.

General Information

      The Contract permits the Contractowner to allocate all or a portion of any
Net Premium Payment and to transfer all or a portion of the Accumulation Value
under the Contract to the Fixed-Rate Option. An Annuitant may not allocate
amounts held under a Certificate to the Fixed-Rate Option. GIAC guarantees that
amounts invested under the Fixed-Rate Option will accrue interest daily at an
effective annual rate of at least 3.5% (the "guaranteed minimum interest rate").
GIAC may also credit interest at a rate in excess of 3.5% (the "excess interest
rate"), but is under no obligation to do so. Any excess interest rate will be
determined at the sole discretion of GIAC and may be changed by GIAC from time
to time and without notice. The Contractowner assumes the risk that interest
credited on any portion of the Accumulation Value in the Fixed-Rate Option may
not exceed the guaranteed minimum interest rate (3.5%) for any given year.

      There is no specific formula for the determination of whether to credit
excess interest or the rate thereof. However, some of the factors that GIAC may
consider are general economic trends, rates of return currently available and
anticipated on GIAC's general account investments, regulatory and tax
requirements and competitive factors. GIAC is aware of no statutory limitations
on the maximum amount of interest it may credit, and the Board of Directors of
GIAC has set no limitations.

      The amounts credited to the Fixed-Rate Option become part of the general
assets of GIAC and are segregated from those allocated to any separate account
of GIAC. GIAC invests the assets of the Fixed-Rate Option in those assets chosen
by GIAC and allowed by applicable law. The allocation of any amounts to the
Fixed-Rate Option does not entitle a Contractowner to share in the investment
experience of those assets.

      The interest rate initially credited to Contract payments or transfers by
the Contractowner to the Fixed-Rate Option will be the rate in effect on the
date such amounts are so allocated. Each such payment or transfer will continue
to receive the rate of interest initially credited until the next Contract
Anniversary Date.

      For a description of certain restrictions which apply to transfers to and
from the Fixed-Rate Option, see "Description of the Contract -- Transfers of
Contract Values."

Renewal Rate and Bailout Provision

      On the Contract Anniversary Date, all payments and transfers allocated to
the Fixed-Rate Option during the prior Contract year, together with all interest
earnings and amounts previously allocated by the Contractowner to the Fixed-Rate
Option, will be credited with the rate of interest in effect on that date (the
"renewal rate"). Such renewal rate will be guaranteed with respect to these
amounts until the next Contract Anniversary Date. If the renewal rate (a) is
more than three (3) percentage points below the interest rate credited for the
immediately preceding Contract year, or (b) falls below the minimum bailout rate
specified in the Contract (where approved by the applicable state insurance
departments), a Contractowner may withdraw all or a portion of the amount which
has been held in the Fixed-Rate Option for one year or more without imposition
of a contingent deferred sales charge. Such withdrawal request must be in
writing and received by GIAC at its Customer Service Office within 60 days of
the Contract Anniversary Date. (See "Surrenders and Partial Withdrawals.")

                           DESCRIPTION OF THE CONTRACT

      This section of the Prospectus highlights the more significant provisions
of the Contract. The information included in this section generally describes,
among other things, the benefits, charges, rights and privileges under the
Contract. These descriptions are qualified by reference to a specimen of the
Contract which has been filed as an exhibit to the registration statement for
the Separate Account. The provisions of the Contract may vary slightly from
state to state due to variations in state regulatory requirements.

General Information

      The Contract is designed to enable a Contractowner to purchase an Annuity
on behalf of Plan Participants who will be entitled to receive payments on a
fixed and/or variable basis, at some later date, pursuant to the terms of the
Plan. The Contract is primarily designed for use with several types of tax
qualified plans, including private retirement plans established by corporate
employers under Section 401 and public employee deferred compensation plans
under Section 457 of the Code as well as other plans which do not receive
favorable tax treatment. The provisions of the Plan should be referred to in
connection with the description of the Contract contained in this Prospectus.

      The Contract offered by this Prospectus is a Flexible Premium Payment
Contract under which Annuity Payments to Plan Participants will begin at
selected future dates on a basis which is elected by the Contractowner in
accordance with the Plan. A minimum premium payment of $5,000 is required with
additional payments of at least $500 accepted. The aggregate of premium payments
made in any Contract year may not exceed $100,000 without GIAC's written
consent. Subject to these restrictions, the amount and frequency of the premium
payments made by the Contractowner may vary pursuant to the terms of the
applicable Plan.

      The variable annuity payments provided by the Contract are funded through
investments in the Separate Account. Information regarding the Investment
Divisions of the Separate Account is contained in the sections entitled
"Descriptions of GIAC and the Separate Account," and "Descriptions of the
Variable Investment Options."

Purchasing a Contract

      Entities wishing to purchase a Contract must complete an application and
send it with an initial premium payment to The Guardian Insurance & Annuity
Company, Inc., Customer Service Office, P.O. Box 26210, Lehigh Valley,
Pennsylvania 18002. Certified, registered or express mail deliveries must be
addressed to: The Guardian Insurance & Annuity Company, Inc., Customer Service
Office, 3900 Burgess Place, Bethlehem, Pennsylvania 18017.

      If the application is acceptable to GIAC in the form received, the initial
Net Premium Payment will be credited within two (2) business days after receipt.
Acceptance is subject to GIAC's rules and GIAC reserves the right to reject any
application or initial premium payment. If the initial Net Premium Payment
cannot be credited within five (5) business days after receipt by GIAC because
the application is incomplete, GIAC will promptly return the premium payment and
application to the applicant.

      After issuance of the Contract, net premium payments received by GIAC at
its Customer Service Office prior to the close of GIAC's business day will
normally be credited to the Contract on that day. Net premium payments received
on a non-business day or following the close of GIAC's business day will be
credited at the next accumulation unit value calculated on the first business
day following receipt.


                                       17

Charges and Deductions

      Charges and deductions under the Contract are made for GIAC's assumption
of mortality and expense risks, administrative expenses, any applicable state
premium taxes, and, where applicable, charges (or credits) to the non-tax
qualified allocations to the Variable Investment Options for any Federal income
taxes. The Separate Account does not incur any operating expenses or account
fees and expenses. Although no sales charges are deducted from premium payments
when made, a contingent deferred sales charge will be assessed upon certain
Contract surrenders or withdrawals. Each charge and deduction under the Contract
is described below:

      Contingent Deferred Sales Charge: GIAC does not deduct a separate sales
charge in connection with premium payments. However, a contingent deferred sales
charge ("CDSC") is imposed by GIAC on certain surrenders or partial withdrawals
to cover certain expenses incurred in the sale of the Contracts, including
commissions to registered representatives and various promotional expenses.

      The CDSC will be the lesser of: (1) 6% of the total payments made during
the 84 months immediately preceding the date of withdrawal annually; or (2) 6%
of the amount being withdrawn. However, after the first Contract year, 10% of
the Accumulation Value as of the first withdrawal in a Contract year or 10% of
the total premium paid under the Contract in the 84 months immediately preceding
the date of withdrawal, whichever is greater, can be withdrawn by the
Contractowner without application of the CDSC. The maximum amount of the CDSC
during the 84 months immediately preceding the date of withdrawal will not
exceed 6% of the total of payments made during such period. Such withdrawals
may, however, be subject to penalty taxes and/or mandatory federal income tax
withholding. (See "Federal Tax Matters".) The CDSC is not charged against
withdrawals of amounts that have been on deposit for more than 84 months.

      To minimize the amount of the CDSC charged in any particular situation,
withdrawals from any Variable Investment Option or the Fixed-Rate Option will be
made in the same order in which amounts were allocated to that Option, subject
to the cancellation ordering rules set forth in "Surrenders and Partial
Withdrawals."

      No CDSC is imposed on Accumulation Units redeemed by the Contractowner to
purchase Annuities for Plan Participants.

      Administrative Expenses: Prior to the Annuity Commencement Date of the
last annuitizing Participant, GIAC deducts a contract administration fee of $35
from the Accumulation Value on the Anniversary Date of each Contract by
cancelling the number of Accumulation Units equal in value to the fee. This
administrative fee is deducted from the Variable Investment Options and the
Fixed-Rate Option on a pro-rata basis in the same proportion as the percentage
of the Contract's Accumulation Value attributable to each Variable Investment
Option and the Fixed-Rate Option. GIAC will not increase the deduction for
administrative expenses above $35 per year. GIAC will deduct the contract
administration fee upon any surrender of a Contract which occurs before the
Contract Anniversary Date. The deduction for administrative expenses is designed
to reimburse GIAC for its actual expenses incurred in administering the
Contracts and it is not expected to result in a profit.

      Premium Taxes: Certain states and municipalities impose premium taxes when
premium payments are made or when annuity payments begin. These taxes ranging
from approximately 0.50% to 3.5% of premium payments made for the Contracts. For
those Contracts subject to premium tax, GIAC deducts premium tax either from
premium payments when made or upon each annuitization, as determined in
accordance with applicable law. However, in those jurisdictions where the
premium tax is required to be deducted at the time of premium payment, GIAC
reserves the right, if permitted by applicable law and with the consent of the
Contractowner, to pay the premium tax on behalf of the Contractowner and deduct
the amount paid from the Contract Value at the first to occur of surrender,
death or the Retirement Date.


                                       18
<PAGE>

      Mortality and Expense Risk Charge: The mortality risk assumed by GIAC
arises from its contractual obligation to continue to make Annuity Payments
(determined in accordance with the annuity tables and other provisions of the
Contract) to each Annuitant regardless of how long he or she lives and
regardless of how long all Annuitants as a group live. This assures each
Annuitant that neither his or her own longevity nor an improvement in general
life expectancy will adversely affect the Annuity Payments he or she will
receive under a Plan, and relieves the Annuitant from the risk that he or she
will outlive the amounts actually accumulated for retirement. The expense risk
assumed by GIAC arises from the possibility that the amounts deducted for sales
and administrative expenses may be insufficient to cover the actual cost of such
items.

      GIAC makes a daily charge against the net assets of each Variable
Investment Option in an amount equal to 1.15% on an annual basis (consisting of
approximately .70% for mortality risks and approximately .45% for expense risks)
to compensate it for the assumption of mortality and expense risks. If this
charge is insufficient to cover the actual cost of these risks, the loss will
fall on GIAC. Conversely, if the charge proves more than sufficient, any excess
may be retained by GIAC for profit or used by it to meet any operational
expenses, including those relating to distribution of the Contracts.

      Variable Annuity Payments reflect the investment performance of the
Variable Investment Options but are not affected by changes in actual mortality
experience or by expenses incurred by GIAC in excess of the expense deductions
provided for in each Contract.

   
      Other Charges Applicable to the Funds: The net asset value per share of
each of the Funds reflects investment management fees and certain general
operating expenses paid by the Funds. With the exception of the Small Cap Fund,
the International Fund, the Emerging Markets Fund, Gabelli Capital Asset Fund
and the MFS Growth With Income Series, each of the Funds pays an annual
investment management fee to its investment adviser that equals 0.50% of each
such Fund's average daily net assets. The Small Cap Fund and the MFS Growth With
Income Series each pay its manager an annual management fee of 0.75% of each
Fund's average daily net assets. The annual investment management fee paid to
the adviser of the International Fund and Emerging Markets Fund equals 0.80% of
the International Fund's average daily net assets and 1.00% of the Emerging
Markets Fund's average daily net assets. Gabelli Capital Asset Fund pays its
manager an annual management fee of 1.00% of that Fund's average daily net
assets. No separate fees are payable to the respective sub-investment advisers
of these Funds. (See "The Funds".) The management fees and other expenses
incurred by the Funds are more fully described in the accompanying prospectuses
for the Funds.
    

Accumulation Period

      Allocation of Net Premium Payment: The initial Net Premium Payment will be
used to purchase Accumulation Units in the Investment Divisions or the
Fixed-Rate Option as selected by the Contractowner at the unit values next
computed following receipt and acceptance of the payment by GIAC. Subsequent Net
Premium Payments will be allocated among the underlying Contract options as
initially selected for allocation or pursuant to new allocation instructions
requested by the Contractowner in writing. New allocation instructions will be
implemented by GIAC following their receipt at its Customer Service Office.
However, the Contractowner may not be invested in more than six allocation
options at any given time.

      Crediting Accumulation Units under the Contract: Variable Accumulation
Units represent the interests in the Variable Investment Options and Fixed
Accumulation Units represent the interests in the Fixed-Rate Option. The total
number of Accumulation Units to be credited to a Contractowner's account is the
sum of the portion of the Net Premium Payment allocated to each option divided
by the Accumulation Unit value of each such option as next computed following
receipt and acceptance of the payment by GIAC. The number of Accumulation Units
will not change because of a subsequent change 


                                       19
<PAGE>

in the value of the unit, but the dollar value of Accumulation Units will vary
based upon the investment experience of the Variable Investment Options and
interest credited to the Fixed-Rate Option.

      Accumulation Value: The value of the Contractowner's account within any
particular Variable Investment Option or the Fixed-Rate Option is determined by
multiplying the number of Accumulation Units of that particular option credited
to the account by the applicable current Accumulation Unit value.

      Value of an Accumulation Unit: With respect to a Variable Investment
Option, the value of a Variable Accumulation Unit is determined by multiplying
the value of such Variable Accumulation Unit as of the end of the immediately
preceding Valuation Period by the net investment factor (described below) for
the current Valuation Period. With respect to the Fixed-Rate Option, the value
of a Fixed Accumulation Unit is determined by adding the interest credited on
such Fixed Accumulation Unit since the end of the immediately preceding
Valuation Period to the value of such unit as of the end of such Valuation
Period.

      Net Investment Factor: The net investment factor is a measure of the
investment experience of each Variable Investment Option. For any particular
Valuation Period, the net investment factor is determined by:

            (1) Adding the net asset value of a Fund share as determined at the
      end of such Valuation Period to the per share amount of any dividend and
      other distribution made by the Fund during the period, and

            (2) Dividing by the net asset value of the particular Fund share
      calculated as of the end of the immediately preceding Valuation Period,
      and

            (3) Subtracting from the above result any applicable taxes and the
      mortality and expense risk charge.

Annuity Period

      Annuity Commencement Date: Annuity Payments made to an Annuitant will
begin on his or her Annuity Commencement Date, which is the first day of the
calendar month and year determined under the Plan. This date cannot be later
than the Annuitant's 85th birthday except when otherwise provided for by the
Plan. Following the Annuity Commencement Date, a Participant is referred to as
an Annuitant for purposes of the Contract.

      Annuity Payments: Annuity Payments are available on a fixed or variable
basis or a combination of both. Such payments will be determined on the basis
of: (1) the table specified in the Contract which reflects the nearest age of
the Annuitant; (2) the Annuity Payout Option(s) selected; and (3) the investment
experience of any Variable Investment Options selected. The number and amount of
Annuity Payments will not be affected by the longevity of Annuitants generally
or any increase in the expenses of GIAC in excess of the charges specified in
the Contract. The Annuitant receives the value of a fixed number of Variable
and/or Fixed Annuity Units each month. For the Variable Investment Options, the
value of an Annuity Unit will reflect the investment experience of the amounts
allocated to the Variable Investment Options, and the amount of each Annuity
Payment will vary accordingly.

      Annuity Payout Options: GIAC will issue a Certificate to the Contractowner
for delivery to each Annuitant upon his or her Annuity Commencement Date. Each
Certificate will set forth in substance the amount and terms of the Annuity
Payments and any other benefits the Annuitant may be entitled to under the
Contract. Annuity Payments will be made in accordance with the Annuity Payout
Option known as "Option V-2 -- Life Annuity with 10-Year Guaranteed Period" (see
below), or, if permitted by the Plan, the Annuitant may elect to have Annuity
Payments made under any one of the other variable and/or fixed Annuity Payout
Options specified in the Contract and described below. 


                                       20
<PAGE>

Annuity Payments will be made monthly except that: (1) proceeds of less than
$2,000 on behalf of any Annuitant will be paid in a single sum to that
Annuitant; and (2) GIAC may change the schedule of monthly installment payments
to avoid payments of less than $20 to an Annuitant. An Annuitant may not change
the Payout Option election following receipt of the first Annuity Payment.

      The Annuity Payout Options currently available for both variable and fixed
Annuity Payments under the Contract are as follows (options designated with the
letter "V" are variable options, those designated with the letter "F" are fixed
options):

            Option V-1 -- Life Annuity without Guaranteed Period: Under this
      option, a Variable Annuity Payment will be made monthly during the
      lifetime of the Annuitant ending with the payment preceding the
      Annuitant's death. Option V-1 offers the maximum level of variable monthly
      payments, since there is no guarantee of a minimum number of variable
      payments or provision for a death benefit for Beneficiaries. It would be
      possible under Option V-1 for the Annuitant to receive only one Variable
      Annuity Payment if he or she died before the date of the second Variable
      Annuity Payment, two such payments if he or she died before the date of
      the third Variable Annuity Payment, and so on.

            Option V-2 -- Life Annuity with 10-Year Guaranteed Period: Under
      this option, a Variable Annuity Payment will be made monthly during the
      lifetime of the Annuitant with the provision that if, at the Annuitant's
      death, such payments have been made for less than 10 years (120 months),
      Variable Annuity Payments will be continued during the remainder of such
      period to the Beneficiary. The Beneficiary at any time may elect to redeem
      in whole or in part the commuted value of the current dollar amount of the
      then remaining number of Variable Annuity Payments. If the Beneficiary
      dies while receiving Variable Annuity Payments, the commuted value of the
      current dollar amount of the remaining number of Variable Annuity Payments
      shall be paid in one sum to the estate of the Beneficiary. While the
      Annuitant is living, he or she may change the Beneficiary at anytime
      provided such change is in writing in a form satisfactory to GIAC.

            Option V-3 -- Joint and Survivor Annuity: Under this option, a
      Variable Annuity Payment will be made monthly during the joint lifetimes
      of the Annuitant and a designated second person (joint annuitant) and will
      continue during the lifetime of the survivor in a reduced amount which
      reflects two-thirds of the number of Variable Annuity Units in effect
      while both persons were living. It would be possible under Option V-3 for
      the joint Annuitants to receive only one Variable Annuity Payment if both
      died before the date of the second Variable Annuity Payment, two such
      payments if both died before the date of the third Variable Annuity
      Payment, and so on.

            Option F-1 -- Life Annuity without Guaranteed Period: Under this
      option, a Fixed Annuity Payment will be made monthly during the lifetime
      of the Annuitant ending with the payment preceding the Annuitant's death.
      Option F-1 offers the maximum level of fixed monthly payments, since there
      is no guarantee of a minimum number of fixed monthly payments or provision
      for a death benefit for Beneficiaries. It would be possible under Option
      F-1 for the Annuitant to receive only one Fixed Annuity Payment if he or
      she died before the date of the second Fixed Annuity Payment, two such
      payments if he or she died before the date of the third Fixed Annuity
      Payment, and so on.

            Option F-2 -- Life Annuity with 10-Year Guaranteed Period: Under
      this option, a Fixed Annuity Payment will be made monthly during the
      lifetime of the Annuitant with the provision that if, at the Annuitant's
      death, such payments have been made for less than 10 years (120 months),
      Fixed Annuity Payments will be continued during the remainder of such
      period to the Beneficiary. The Beneficiary at any time may elect to redeem
      in whole or in part the commuted value of the current dollar amount of the
      then remaining number of Fixed Annuity Payments. If the 


                                       21
<PAGE>

      Beneficiary dies while receiving Fixed Annuity Payments, the commuted
      value of the current dollar amount of the remaining number of Fixed
      Annuity Payments shall be paid in one sum to the estate of the
      Beneficiary. While the Annuitant is living he or she may change the
      Beneficiary at any time provided such change is in writing in a form
      satisfactory to GIAC.

            Option F-3 -- Joint and Survivor Annuity: Under this option, a Fixed
      Annuity Payment will be made monthly during the joint lifetimes of the
      Annuitant and a designated second person (joint annuitant) and will
      continue during the lifetime of the survivor in a reduced amount which
      reflects two-thirds of the number of Fixed Annuity Units in effect while
      both persons were living. It would be possible under Option F-3 for the
      joint Annuitants to receive only one Fixed Annuity Payment if both died
      before the date of the second Fixed Annuity Payment, two such payments if
      both died before the date of the third Fixed Annuity Payment, and so on.

Transfers of Contract Values

      General Information: Subject to the conditions described below and to the
terms of any applicable retirement plan, transfers among the Contract's Variable
Investment Options are permitted during both the Accumulation and Annuity
Periods. During the Accumulation Period, the Contractowner may transfer all or a
portion of the Accumulation Units under the Contract among each of the Variable
Investment Options and the Fixed-Rate Option. During the Annuity Period, an
Annuitant receiving payments pursuant to a Variable Annuity Payout Option may
transfer all or a portion of the amounts held under the Certificate among the
Variable Investment Options. Allocations to the Fixed-Rate Option are not
permitted by an Annuitant during the Annuity Period. Contractowners may be
invested in a maximum of six Variable Investment Options or in the Fixed-Rate
Option and five Variable Investment Options under the Contract at any given
time. Annuitants receiving payments pursuant to a Variable Payout Option may be
invested in a maximum of six Variable Investment Options at any given time.
Contractowners and Annuitants who contemplate requesting a transfer should
carefully consider their own objectives and the investment objectives, risks and
restrictions pertaining to each Variable Investment Option and the Fixed-Rate
Option involved in the proposed transfer before making the request. Frequent
transfers may be inconsistent with the long-term objectives of the Contract.

      GIAC will implement transfers pursuant to proper written or telephone
instructions received at its Customer Service Office. Requests received by GIAC
at its Customer Service Office prior to 3:30 p.m. (Eastern time) on a given
business day will normally be implemented as of the end of that day. GIAC
reserves the right to limit the frequency of transfers to not more than once
every 30 days. Currently, no charge is made by GIAC for effecting any transfer.
GIAC reserves the right, however, to impose such a charge in the future.

      Telephone Transfers: Contractowners may effect telephone transfers of the
Accumulation Value under a Contract pursuant to certain terms and conditions.
Telephone transfers of amounts held under a Certificate are not available to
Annuitants. GIAC will not honor telephone transfer instructions unless proper
authorization has been properly provided either in the completed application for
the Contract or in GIAC's telephone transfer authorization form.

      If the proper authorization is on file at GIAC's Customer Service office,
telephone transfer instructions may be given by calling 1-800-533-0099 between
9:00 a.m. and 3:30 p.m. (Eastern time) on days when GIAC is open for business.
Each telephone transfer instruction must include a precise identification of the
Contract and the Contractowner's Personal Security Code. GIAC may accept
telephone transfer instructions from any person who properly identifies the
correct Contract number and Personal Security Code. GIAC, GISC and the Funds
shall not be liable for any loss, damage, cost or expense resulting from
following telephone transfer instructions which any of them reasonably believed
to be genuine. Thus, Contractowners risk possible loss of interest, capital
appreciation and principal in the 


                                       22
<PAGE>

event of an unauthorized or fraudulent telephone transfer. All or part of any
telephone conversation relating to transfer instructions may be recorded by GIAC
without prior disclosure to the caller.

      Telephone transfer instructions apply only to allocations of previously
invested monies. Such instructions may not be used to change the allocation
instructions for any future premiums paid under the Contract. (See "Allocation
of Net Premium Payment" for information about changing allocation instructions
for future premiums.)

      During periods of drastic economic or market changes, it may be difficult
to contact GIAC to request a telephone transfer. At such times, transfer
requests may be made by regular or express mail and will be processed at the
next Accumulation Unit value calculated after their receipt pursuant to the
terms and restrictions described in this "Transfers of Contract Values" section.
GIAC reserves the right to modify, suspend or discontinue the telephone transfer
privilege at any time and without prior notice.

      Transfers from the Fixed-Rate Option to any Variable Investment Option are
permitted only once per Contract year during the 30-day period beginning on the
Contract Anniversary Date. Amounts will be transferred from the Fixed-Rate
Option to any Variable Investment Option in the same order such amounts were
allocated to the Fixed-Rate Option. This means that amounts on deposit in the
Fixed-Rate Option for the longest period of time will be the first amounts so
transferred. The maximum amount which may currently be transferred out of the
Fixed-Rate Option each year is the greater of: (1) 33 1/3% of the amount in
the Fixed-Rate Option as of the applicable Contract Anniversary Date; or (2)
$2,500.

      Each transfer involving the Contract's Variable Investment Options will be
based upon the next Accumulation Unit value calculated after proper transfer
instructions are received by GIAC at its Customer Service Office.

      Transfers of Amounts Held Under a Certificate by an Annuitant: During the
Annuity Period, an Annuitant may transfer all or a portion of the amounts
allocated to a Variable Payout Option among the Variable Investment Options.
However, such transfers may be made only once per year. Any such transfer will
be effected at the next Annuity Unit Value calculated after receipt of proper
transfer instructions by GIAC at its Customer Service Office. An Annuitant may
not transfer into or out of the Fixed-Rate Option.

Surrenders and Partial Withdrawals

      The Contractowner may redeem the Contract in whole (known as a
"surrender") or in part (known as a "partial withdrawal"). Surrenders and
partial withdrawals must be requested in writing in a form acceptable to GIAC. A
surrender request must be accompanied by the Contract (or an acceptable
affidavit of loss) to be deemed a proper written request. GIAC will not process
a surrender request prior to receipt of the Contract (or an acceptable affidavit
of loss) at its Customer Service Office.

      A contingent deferred sales charge may be imposed upon certain surrenders
or partial withdrawals. (See "Charges and Deductions -- Contingent Deferred
Sales Charge.")

      A surrender or partial withdrawal is effected by cancelling Accumulation
Units which have an aggregate value equal to the dollar amount of the requested
surrender or partial withdrawal as next calculated following receipt by GIAC at
its Customer Service Office of a proper written request for the surrender or
partial withdrawal. If applicable, any Contract charges and any contingent
deferred sales charge will be deducted from the surrender proceeds or, in the
case of a partial withdrawal, from the remaining Accumulation Value by the
cancellation of additional Accumulation Units. If the Accumulation Value
remaining after a partial withdrawal is less than $1,000, GIAC will redeem the
total Accumulation Value and pay it to the Contractowner in cancellation of the
Contract. Such an involuntary surrender 


                                       23
<PAGE>

may be subject to any then applicable Contract administrative charge or
contingent deferred sales charge. (See "Charges and Deductions -- Contingent
Deferred Sales Charge.")

      Except as noted below, Accumulation Units will be cancelled in the
following order: First, GIAC will cancel all the Variable Accumulation Units
attributable to the Investment Divisions. Cancellation of the Variable
Accumulation Units attributable to the Investment Divisions will be on a pro
rata basis, reflecting the existing distribution of the Variable Accumulation
Units unless the Contractowner instructs otherwise. Second, GIAC will cancel all
Fixed Accumulation Units attributable to the Fixed-Rate Option. Thus, GIAC will
have cancelled all the Variable Accumulation Units attributable to the
Investment Divisions before cancelling Accumulation Units attributable to the
Fixed-Rate Option. Accumulation Units used by a Contractowner to purchase
Annuities for Plan Participants will be cancelled in the same order as those in
connection with a surrender or partial withdrawal.

      No contingent deferred sales charge will be imposed and the above ordering
rules will not apply if amounts are withdrawn directly from the Fixed-Rate
Option in accordance with the bailout provision described in the section
entitled "Description of the Fixed-Rate Option."

      Payment of a surrender or partial withdrawal will ordinarily be made
within seven (7) days after the date GIAC receives the proper written request at
its Customer Service Office. GIAC can delay the payment if the Contract is being
contested and may postpone the calculation or payment of any Contract benefit or
transfer of amounts based on investment performance of the Investment Divisions
if: (1) the New York Stock Exchange is closed for trading or trading has been
suspended; or (2) the Securities and Exchange Commission restricts trading or
determines that a state of emergency exists which may make payment or transfer
impracticable.

      An Annuitant may not request a surrender or partial withdrawal following
the receipt of the first Annuity Payment.

      Questions regarding GIAC's surrender or withdrawal procedures should be
directed to a customer service representative by calling toll-free
1-800-221-3253.

Other Important Contract Information

      Dollar Cost Averaging: Contractowners may elect to systematically, on a
long term basis if desired, transfer specified level dollar amounts from the
Cash Fund Investment Division to other Variable Investment Options and/or the
Fixed-Rate Option at regular intervals. By transferring specific amounts on a
regularly scheduled basis, as opposed to allocating the total amount at one
particular time, the Accumulation Value may be less susceptible to the impact of
market fluctuations. There is no guarantee, however, that such an investment
method will result in profits or prevent losses.

      To take advantage of this program, a Contractowner predesignates a dollar
amount to be automatically transferred from the Cash Fund Investment Division to
one or more of the other Variable Investment Options and/or the Fixed-Rate
Option, provided that Accumulation Values may only be allocated among a maximum
of four Contract options, including the Cash Fund Investment Division, at any
given time. A Contractowner may elect this program when the Contract is
purchased or anytime thereafter by properly completing the Contract application
or Dollar Cost Averaging election form and returning it to GIAC at its Customer
Service Office at least three (3) business days prior to the Monthly Anniversary
Date (the monthly anniversary measured from the issue date of the Contract or
the last day of that calendar month, if earlier) on which the first transfer
will be made. Transfers will then be made monthly for the period elected by the
Contractowner.

      Dollar Cost Averaging may be selected for 12, 24 or 36 month periods. The
total Accumulation Value at the time it is elected must be at least $10,000 for
transfers over a 12 month period and $20,000 for transfers over a 24 or 36 month
period. Transfers will be made in the amounts designated by the 


                                       24
<PAGE>

Contractowner and must be at least $100 per receiving Contract option. When a
Contractowner elects to participate in this program, the Accumulation Value
attributable to the Cash Fund Investment Division must be at least equal to the
amount designated to be transferred on each Monthly Anniversary Date multiplied
by the duration selected.

      Dollar Cost Averaging will terminate when any one of the following events
occurs: (1) the number of designated monthly transfers has been completed; (2)
the Accumulation Value attributable to the Cash Fund Investment Division is
insufficient to complete the next transfer; (3) the Contractowner requests
termination in a writing received by GIAC at its Customer Service Office at
least three (3) business days prior to the next Monthly Anniversary Date; or (4)
the Contract is surrendered.

      A Contractowner may reinstate Dollar Cost Averaging or change existing
Dollar Cost Averaging terms by properly completing a new election form. Such
requests received by GIAC at its Customer Service Office at least three (3)
business days prior to the next Monthly Anniversary Date will be effective for
such Monthly Anniversary Date.

      When utilizing Dollar Cost Averaging, a Contractowner must be invested in
the Cash Fund Investment Division and may be invested in either (i) a maximum of
five other Variable Investment Options or (ii) in the Fixed-Rate Option and a
maximum of four other Variable Investment Options. The Dollar Cost Averaging
program may not be elected by an Annuitant.

      Assignment: Assignment of an interest in the Contract is generally
prohibited when the Contract is used in connection with any retirement plans
contemplated by Section 401 of the Code and any corporate retirement plan. An
assignment of the Contract may be treated as a taxable distribution to the
Contractowner. (See "Federal Tax Matters.")

      Reports: GIAC will send to each Contractowner, at least semi-annually, a
report containing such financial information pertaining to the Separate Account
as may be required by applicable laws, rules and regulations. In addition, a
statement will be provided to each Contractowner at least annually which reports
the number of Contract Accumulation Units and the value of such Accumulation
Units under the Contract.

      Contractowner Inquiries: A Contractowner may direct inquiries to the
individual from whom the Contract was purchased or may call GIAC at
1-800-221-3253 or write directly to: The Guardian Insurance & Annuity Company,
Inc., Customer Service Office, P.O. Box 26210, Lehigh Valley, Pennsylvania
18002.

                               PERFORMANCE RESULTS

      From time to time, performance information for the Account's Investment
Divisions maybe provided in advertisements, sales literature or materials
furnished to existing or prospective Contractowners. All such information is
based upon historical information and is not necessarily representative of
future performance. More detailed information about the calculation of such
historical performance information appears in the Statement of Additional
Information.

      Total Returns: "Average annual total return," "total return" and "change
in Accumulation Unit value" all reflect the change in the value of an investment
in an Investment Division over a specified period, assuming the reinvestment of
all income dividends and capital gains distributions. Average annual total
returns show the average annual percentage change in value over a specified
period. Total returns and changes in Accumulation Unit values, which are not
annualized, show the total percentage change in value over a specified period.

      Promotional materials relating to an Investment Division's investment
performance will always at least provide the average annual total returns for
each of a short (one to four years), medium (five to nine years) and long (ten
years or more) period of time for the Division's corresponding Fund. Such
required average annual total returns will reflect the effects of all charges,
both recurring and non-recurring, incurred by the Fund, as well as all charges
deducted under the terms of the Contracts. However, promotional materials may
also show average annual total returns which assume that a Contract continues in
force after the end of the specified period. Such returns will not reflect the
effects of the Contract's contingent deferred sales charge. Total returns and
changes in Accumulation Unit values may not reflect certain specified charges
deducted under the terms of the Contracts.

      Yields: "Yield" figures may be quoted for the Investment Divisions which
invest in shares of the Cash Fund and the Bond Fund. Current yield is a measure
of the net investment income earned on a hypothetical investment over a
specified base period of seven days for the Cash Fund Investment Division and 30
days (or one month) for the Bond Fund Investment Division. Yield is expressed as
a percentage of the value of an Accumulation Unit at the beginning of the base
period. Yields are annualized, which means that they assume that an Investment
Division will generate the same level of net investment income over a one-year
period. However, yields actually fluctuate daily.

      The Cash Fund Investment Division may also quote its "effective yield,"
which assumes that the net investment income earned during a base period will be
earned and reinvested for a year. The effective yield will be slightly higher
than the Cash Fund Investment Division's current yield due to the compounding
effect created by assuming reinvestment of the Division's net investment income.

      Distribution Rates: On occasion, the Bond Fund Investment Division may
quote historical or annualized distribution rates. A distribution rate is simply
a measure of the level of income dividends and short-term capital gains
distributed for a specified period. A distribution rate is not a complete
measure of performance and may be higher than yield for certain periods.

      Comparative and Other Information: Advertisements and sales literature for
the Separate Account's Investment Divisions may compare a Fund's performance to
that of other investment vehicles or other mutual funds having similar
objectives or programs which are offered through the separate accounts of other
insurance companies. Promotional materials may also compare a Fund's performance
to one or more indices of the types of securities which the Fund buys and sells
for its portfolio, and be illustrated by tables, graphs or charts. Promotional
materials may additionally contain references to types and characteristics of
certain securities; features of a Fund's portfolio; financial markets; or
historical, current or perceived economic trends within the United States or
overseas. Topics of general investor interest, such as personal financial
planning, may also be discussed.

      In addition, advertisements and sales literature may refer to or reprint
all or portions of articles, reports, 


                                       26
<PAGE>

or independent rankings or ratings which relate to the Investment Division
specifically, or to other comparable mutual funds or investment vehicles. None
of the contents of such materials will be used to indicate future performance.

      Further information about each Investment Division's performance is
contained in their respective Annual Report, which may be obtained from GISC
free of charge.

      Advertisements and sales literature about the Contracts and the Separate
Account may also refer to ratings given to GIAC by insurance company rating
organizations, such as Moody's Investors Service, Inc., Standard & Poor's
Ratings Group, A.M. Best & Co. and Duff & Phelps. Such ratings relate only to
GIAC's ability to meet its obligations under the Contract's Fixed-Rate Option.

                               FEDERAL TAX MATTERS

General Information

      The operations of the Separate Account form a part of, and are taxed with
GIAC's operations under the Code. Investment income and realized net capital
gains on the assets of the Separate Account are reinvested and taken into
account in determining the Accumulation and Annuity Unit values. Thus,
investment income and realized net capital gains are automatically applied to
increase reserves under the Contract. GIAC believes that investment income and
capital gains attributable to the Separate Account are taxed under existing
Federal income tax law but are offset by deductible reserve increases.
Accordingly, GIAC does not anticipate that it will incur any Federal income tax
liability attributable to the Separate Account and, therefore, GIAC does not
currently make provisions for any such taxes. However, if changes in the Federal
tax laws, or interpretations thereof, result in GIAC incurring a tax liability
on income or gains attributable to the Separate Account or certain types of
variable annuity contracts, then GIAC may impose a charge against the Separate
Account (with respect to some or all Contracts) to pay such taxes.

Non-Qualified Contracts

      Diversification: Section 817(h) of the Code provides that variable annuity
contracts will not be treated as annuities unless the underlying investments are
"adequately diversified" in accordance with regulations prescribed by the
Secretary of the Treasury. Such regulations require, among other things, that
the Funds invest no more than 55% of the value of their respective assets in one
investment; 70% in two investments; 80% in three investments; and 90% in four
investments. GIAC intends that the Funds underlying the Contracts will be
managed by the applicable investment managers so as to comply with these
diversification requirements. If the diversification requirements are not met by
each and every Variable Investment Option, the Contract could lose its overall
tax status as an annuity, resulting in current taxation of the excess of
Contract value over the "investment in the Contract." A Contractowner's
"investment in the Contract" generally equals: (1) the aggregate amount of
premium payments or other consideration paid for the Contract minus (2) the
aggregate amount received under the Contract, to the extent such amount was not
excluded from gross income.

   
      Owner Control: In certain circumstances, owners of variable annuity
contracts may be considered the owners, for federal income tax purposes, of the
assets of the separate accounts used to support their contracts. In those
circumstances, income and gains from the separate account assets would be
includable in the variable contractowner's gross income. The IRS has stated that
a variable contractowner will be considered the owner of separate account assets
if the contractowner possesses incidents of ownership in those assets, such as
the ability to exercise investment control over the assets. To date, no
regulations or rulings have been issued regarding the circumstances under which
a contractowner's ability to control investments through premium allocation and
transfer privileges would cause him or her to be treated as the owner of the
assets in an insurance company's separate account. GIAC does not know what
standards will be set forth, if any, in the regulations or rulings which the
Treasury Department has stated it expects to issue to provide guidance in this
area. Accordingly, GIAC reserves the right to modify the Contract as necessary
to attempt to prevent the Contractowner from being considered the owner of the
assets of the Separate Acount or otherwise to maintain favorable tax treatment
of the Contracts.
    

      Distribution of Benefits: Non-qualified Contracts will not be treated as
annuity contracts for purposes of Section 72 of the Code unless the Contract
provides that: (1) if any Contractowner dies on or after the Annuity
Commencement Date, but prior to the time the entire interest in the Contract has
been distributed, the remaining portion of such interest will be distributed at
least as rapidly as under the method of distribution in effect when the
Contractowner died; and (2) if any 


                                       28
<PAGE>

Contractowner dies prior to the Annuity Commencement Date, the entire interest
will be distributed within five years of the Contractowner's death. These
requirements will be considered satisfied if that portion of the Contractowner's
interest which is payable to or for the benefit of a "designated beneficiary,"
will be distributed over the life or life expectancy of any new owner and such
distributions begin within one year of the Contractowner's death. The Contract's
"new owner" is the person designated by the Contractowner as Beneficiary and to
whom ownership of the Contract passes by reason of death. For this purpose, the
Beneficiary must be a natural person. If the Beneficiary is the Contractowner's
surviving spouse, the Contract may be continued with the surviving spouse as the
new Contractowner. Non-qualified Contracts contain provisions intended to comply
with Section 72(s) of the Code. However, regulations interpreting these
requirements of the Code have not yet been issued. Accordingly, the provisions
contained in such Contracts will be reviewed and may be modified to assure
compliance with the Code's requirements when clarified by regulations or
otherwise.

      Note: The remaining discussion concerning non-qualified Contracts assumes
that the Contracts will be treated as annuities under Section 72 of the Code,
that the underlying investments of the Contracts are "adequately diversified"
under Section 817(h) of the Code, and that the Contract is not issued in
connection with a retirement plan qualifying for favorable tax treatment under
the Code.

      A Contractowner who is a natural person is generally not taxed on
increases in the value of a Contract until distribution, either as a lump sum
payment received by surrender or partial withdrawal, or as annuity payments. The
assignment or pledge of any portion of the Contract value may be treated as a
distribution. The taxed portion of a distribution (whether in the form of a lump
sum payment or an annuity) is taxed as ordinary income.

      Contractowners who are not natural persons generally must include in
income any increase in the excess of the Contract's Accumulation Value over the
"investment in the Contract" during the taxable year, whether or not such
increase is distributed. There are some exceptions to this rule and a
prospective owner that is not a natural person may wish to discuss these with a
competent tax adviser.

      The following discussion applies to Contracts owned by natural persons.

      Generally, accounts received by surrender or partial withdrawal are first
treated as taxable income to the extent that the Contract's Accumulation Value
immediately before the surrender/withdrawal exceeds the "investment in the
contract." Any additional amount withdrawn is not taxable.

      Although the tax consequences may vary depending on the form of Annuity
Payout Option selected, the recipient of an Annuity Payment generally is taxed
on the portion of such payment that exceeds the "investment in the contract."
For variable annuity payments, the taxable portion is determined by a formula
that establishes a specific dollar amount of each payment that is not taxed. The
dollar amount is determined by dividing the "investment in the contract" by the
total number of expected periodic payments. The entire distribution will be
fully taxable once the recipient has recovered the dollar amount of the
"investment in the contract."

      A penalty tax on surrenders or withdrawals equal to 10% of the amount
treated as taxable income may be imposed unless such surrender or withdrawal is:
(1) made on or after age 59 1/2; (2) made as a result of death or disability;
or (3) received in substantially equal installments as a life annuity (subject
to special "recapture" rules if the series of payments is subsequently
modified).

      Annuity distributions are generally subject to withholding for the
recipient's income tax liability. The withholding rates vary according to the
type of the distribution and the recipient's tax status. Recipients generally
may elect not to have tax withheld from distributions. Redemption requests that
do not indicate a preference regarding withholding will be delayed in processing
until a preference form has been properly completed and received at GIAC's
Customer Service Office. Withholding on 


                                       29
<PAGE>

taxable distributions is generally required if the recipient fails to provide
GIAC with his or her correct Social Security number or if the recipient is a
U.S. citizen or expatriate living abroad.

      Amounts may be distributed from a Contract because of the death of a
Contractowner or the Annuitant. Generally, such amounts are includable in the
income of the recipient as follows: (1) if distributed in a lump sum they are
taxed in the same manner as a full surrender of the Contract as described above;
or (2) if distributed under an annuity option, they are taxed in the same manner
as annuity payments as described above. For these purposes, the investment in
the contract is not affected by the Contractowner's or Annuitant's death. That
is, the investment in the contract remains the amount of any purchase payments
paid which were not excluded from gross income.

      All non-qualified deferred annuity contracts that are issued by GIAC or
its affiliates to the same Contractowner during any calendar year are to be
aggregated for purposes of determining the amount includable in the
Contractowner's gross income under Section 72(e) of the Code. Thus, the proceeds
of a partial withdrawal, surrender or assignment of one or more non-qualified
deferred annuity contracts entered into during the same calendar year will be
includable in the Contractowner's income to the extent of the aggregate excess
of the accumulation values over the investment in all such contracts
("investment in the contract" is defined above). Potential purchasers of more
than one non-qualified annuity contract should seek advice from legal or tax
counsel as to the possible implications of these rules on the contracts they
intend to purchase.

   
      Transferring the ownership of a Contract, or designating an Annuitant,
payee or other Beneficiary who is not also the Contractowner, the selection of
certain Annuity Commencement Dates, or the assignment or exchange of a Contract,
may result in certain income or gift tax consequences to the Contractowner that
are beyond the scope of this discussion. A Contractowner contemplating any such
transfer, designation, selection, assignment or exchange of a Contract should
contact a competent tax adviser about the potential tax effects of such a
transaction.

      Possible Tax Changes: Although the likelihood of legislative change is
uncertain, there is always the possibility that the tax treatment of the
Contracts could change by legislation or other means. For instance, the
President's 1999 Budget Proposal recommended legislation that, if enacted, would
adversely modify the federal taxation of the Contracts. It is also possible that
any change could be retroactive (that is, effective prior to the date of the
change). A tax adviser should be consulted with respect to legislative
developments and their effect on the Contract.
    

Qualified Contracts

   
      Generally, increases in the value of amounts under a Contract purchased in
connection with a retirement plan qualifying for favorable tax treatment under
the Code are not taxable until benefits are received. However, the rules
governing the tax treatment of contributions and distributions under qualified
plans, as set forth in the Code and applicable rulings and regulations, are
complex and subject to change. These rules also vary according to the type of
plan and the terms and conditions of the plan itself. Therefore, this Prospectus
does not attempt to provide more than general information about the use of the
Contracts with these various types of plans. Contractowners, Annuitants, and
Beneficiaries under qualified plans should be aware that the rights of any
person to any benefits under such plans may be subject to the terms and
conditions of the plans, regardless of the terms and conditions of the Contracts
issued in connection with such plans. Some retirement plans are subject to
distribution and other requirements that are not incorporated into GIAC's
Contract administration procedures. Contractowners, participants and
beneficiaries are responsible for determining that contributions, distributions
and other transactions with respect to the Contracts comply with applicable law.
Adverse tax consequences may result from contributions in excess of specified
limits; distributions prior to age 59 1/2 (subject to certain exceptions);
distributions that do not conform to specified commencement and minimum
distribution rules; and in other specified circumstances. Purchasers of
Contracts for use 


                                       30
<PAGE>

with any retirement plan should consult their legal counsel and tax adviser
regarding the suitability of the Contract.

      For qualified plans under Section 401(a), 403(a), 403(b), and 457, the
Code requires that distributions generally must commence no later than the later
of April 1 of the calendar year following the calendar year in which the
Contractowner (or plan participant) (i) reaches age 70 1/2 or (ii) retires, and
must be made in a specified form or manner. If the plan participant is a "5
percent owner" (as defined in the Code), distributions generally must begin no
later than April 1 of the calendar year following the calendar year in which the
Contractowner (or plan participant) reaches age 70 1/2. For IRAs described in
Section 408, distributions generally must commence no later than the later of
April 1 of the calendar year following the calendar year in which the
Contractowner (or plan participant) reaches age 70 1/2.
    

      Following are brief descriptions of the various types of plans with which
the Contracts described in this Prospectus may be used:

   
            Section 403(b) Plans: The Code permits public schools and employers
      specified in Section 501(c)(3) of the Code to purchase annuity contracts
      under section 403(b) and mutual fund shares through a Section 403(b)(7)
      custodial account on behalf of their employees. Subject to certain
      limitations, the purchase payments for such contracts or mutual fund
      shares are excluded from the employees' gross income for tax purposes.
      However, these payments may be subject to FICA (Social Security) taxes.
      These annuity contracts are commonly referred to as "tax-sheltered
      annuities."

            Distributions from tax-sheltered annuities are restricted unless the
      employee is age 59 1/2, separates from service, dies, becomes disabled, or
      incurs a hardship. Before one of these events occurs, the employee may not
      surrender amounts attributable to either: (1) salary reduction
      contributions made in years beginning after December 31, 1988; (2) income
      attributable to salary reduction contributions made in years beginning
      after December 31, 1988; or (3) income in years beginning after December
      31, 1988 on salary reduction accumulations held as of December 31, 1988.
      Hardship withdrawals are further limited to salary reduction contributions
      only, and may not include income earned thereon. Hardship withdrawals are
      generally subject to tax penalties and contingent deferred sales charges.
    

            If a Contract is purchased as a tax-sheltered annuity under Section
      403(b) of the Code, it is subject to the restrictions on redemption
      described above. These restrictions on redemption are imposed by the
      Separate Account and GIAC in full compliance with and in reliance upon the
      terms and conditions of a no-action letter on this subject issued by the
      staff of the Securities and Exchange Commission.

   
            The Contract includes a death benefit that in some cases may exceed
      the greater of the Purchase Payments or the Contract Value. The death
      benefit could be characterized as an incidental benefit, the amount of
      which is limited in any tax-sheltered annuity under section 403(b).

            Prospective purchasers of the Contracts as tax-sheltered annuities
      should seek advice from legal or tax counsel about their eligibility to
      purchase a tax-sheltered annuity, limitations on permissible amounts of
      purchase payments, distribution restrictions, the Contract's death benefit
      provision and tax consequences of distribution.

            Individual Retirement Accounts: Sections 219 and 408 of the Code
      permit individuals to contribute to an individual retirement program known
      as an "Individual Retirement Account" or "IRA." IRA contributions are
      generally limited each year to the lesser of $2,000 or 100% of the
      Contractowner's adjusted gross income and may be deductible in whole or in
      part depending on the individual's income. Distributions from certain
      other types of qualified plans, however, may be 


                                       31
<PAGE>

      "rolled over" on a tax-deferred basis into an IRA without regard to this
      limit. Earnings in an IRA are not taxed while held in the IRA. All amounts
      in the IRA (other than nondeductible contributions) are taxed when
      distributed from the IRA. Distributions prior to age 59 1/2 (unless
      certain exceptions apply) are also subject to a 10% penalty tax.
      Individuals who purchase Contracts for use with an IRA will receive, in
      addition to this Prospectus and a copy of the Contract, a brochure
      containing information about eligibility, contribution limits, tax
      consequences and other particulars concerning IRAs. The Internal Revenue
      Service has not reviewed the Contract for qualification as an IRA, and has
      not addressed in a ruling of general applicability whether a death benefit
      provision such as the provision in the Contract comports with IRA
      qualification requirements.

            Corporate Pension and Profit-Sharing Plans: Section 401(a) of the
      Code permits corporate employers to establish various types of retirement
      plans for employees, and self-employed individuals to establish qualified
      plans for themselves and their employees. These retirement plans may
      permit the purchase of the Contracts to accumulate retirement savings
      under the plans. Adverse tax or other legal consequences to the plan, to
      the participant or to both may result if this Contract is assigned or
      transferred to any individual as a means to provide benefit payments,
      unless the plan complies with all legal requirements applicable to such
      benefits prior to transfer of the Contract. The Contract includes a death
      benefit that in some cases may exceed the greater of the Purchase Payments
      or the Contract Value. The death benefit could be characterized as an
      incidental benefit, the amount of which is limited in any pension or
      profit-sharing plan. Because the death benefit may exceed this limitation,
      employers using the Contract in connection with such plans should consult
      their tax adviser.

            Deferred Compensation Plans: Section 457 of the Code provides for
      certain deferred compensation plans with respect to service for state
      governments, local governments, rural electric cooperatives, political
      subdivisions, agencies, instrumentalities, certain affiliates of such
      entities and other tax-exempt employers. Amounts contributed by employers
      through such plans are taxed to employees when paid or made available for
      withdrawal. Under such plans, a participant may specify the form of
      investment in which his or her contributions will be made. In general, all
      such investments are owned by, and are subject to the claims of the
      general creditors of, the sponsoring employer and, depending on the terms
      of the particular plan, the employer may be entitled to draw on deferred
      amounts for purposes unrelated to its Section 457 plan obligations. In
      certain governmental plans, however, deferred amounts must be held in
      trust for the exclusive benefit of plan participants.
    

      The following rules generally apply to distributions from Contracts
purchased in connection with the plans (other than Section 457 plans) discussed
above:

   
      That portion of any contribution under a Contract made by or on behalf of
an individual (typically an employee) which is not excluded or deductible from
his or her gross income (generally, the individual's own nondeductible
contribution) constitutes his or her "investment in the contract." If a
distribution is made in the form of annuity payments, the investment in the
contract (adjusted for certain refund provisions) divided by the Annuitant's
life expectancy (or other period for which annuity payments are expected to be
made) constitutes a tax-free return of capital each year. The entire
distribution will be fully taxable once the Annuitant (or other appropriate
payee) is deemed to have recovered the dollar amount of the investment in the
Contract. The dollar amount of annuity payments received in any year in excess
of such return is taxable as ordinary income. Depending upon the nature and
structure of the arrangement in connection with which a Contract is issued, an
individual's investment in the Contract can be zero.
    

      If a surrender of or partial withdrawal from a Contract held in connection
with a Section 401(a) plan is effected and a distribution is made in a single
payment, the proceeds may qualify for special "lump-


                                       32
<PAGE>

sum distribution" treatment. Otherwise, the amount by which the payment exceeds
the "investment in the contract" (adjusted for any prior partial withdrawal)
will generally be taxed as ordinary income in the year of receipt, unless it is
validly "rolled over" into an IRA or another qualified plan.

   
      A penalty tax of 10% will be imposed on the taxable portion of surrenders
or partial withdrawals from all qualified Contracts, except under circumstances
similar to those relating to non-qualified Contracts (see above). Other adverse
tax consequences may result if distributions do not conform to specified
commencement and minimum distribution rules, and in other circumstances.

      The taxation of benefits payable upon an employee's death to his or her
Beneficiary generally follows these same principles, subject to a variety of
special rules. In particular, tax on death benefits to be paid as a lump sum
under a non-qualified contract may be deferred if, within 60 days after the lump
sum becomes payable, the Beneficiary instead elects to receive annuity payments.

      Distributions from Contracts generally are subject to withholding for the
Contractowner's federal income tax liability. The withholding rate varies
according to the type of distribution and the Contractowner's tax status. The
Contractowner will be provided the opportunity to elect not to have tax withheld
from distributions. "Eligible rollover distributions" from section 401(a) plans
and section 403(b) tax-sheltered annuities are subject to a mandatory federal
income tax withholding of 20%. An eligible rollover distribution is the taxable
portion of any distribution from such a plan, except certain distributions such
as distributions required by the Code or distributions in a specified annuity
form. The 20% withholding does not apply, however, if the Contractowner chooses
a "direct rollover" from the plan to another tax-qualified plan or IRA.
    

      Restrictions under Qualified Contracts: Other restrictions with respect to
the election, commencement, or distribution of benefits may apply under
Qualified Contracts or under the terms of the plans in respect of which
Qualified Contracts are issued.

Other Considerations

      Presently, GIAC makes no charge to the Separate Account for any Federal,
state or local taxes (other than state premium taxes) that it incurs which may
be attributable to the Separate Account or to the Contracts. GIAC, however,
reserves the right to make a charge for any such taxes or other economic burden
which may result from the application of the tax laws and that GIAC determines
to be attributable to the Separate Account or to the Contracts. If any tax
charges are made in the future, they will be accumulated daily and transferred
from the Separate Account to GIAC's general account.

      Because of the complexity of the Federal tax law, and the fact that tax
results will vary according to the factual status of the entity or individual
involved, tax advice may be needed by anyone contemplating the purchase of a
Contract or the exercise of the various elections under the Contract. It should
be understood that this Prospectus' discussion of the Federal income tax
consequences of owning a Contract is not an exhaustive discussion of all tax
questions that might arise under the Contracts and that special rules exist in
the Code with respect to situations not discussed here. No representation is
made regarding the likelihood of the continuation of current Federal tax laws or
interpretations thereof by the Internal Revenue Service. No attempt has been
made to consider any applicable state, local or other tax laws, except with
respect to the imposition of any premium taxes.

      GIAC does not make any guarantee regarding the tax status of any Contract
and the above tax discussion is not intended as tax advice.


                                       33
<PAGE>

                                  VOTING RIGHTS

      To the extent required by applicable law, GIAC will vote the Fund shares
that it owns through the Separate Account according to instructions received
from Contractowners having an interest in such Fund's shares. GIAC will vote
shares for which no instructions are received in the same proportion as it votes
shares for which it has received instructions. GIAC will vote any Fund shares
that it is entitled to vote directly due to amounts it has contributed or
accumulated in the applicable Investment Division for proposals presented by
Fund Management. If the applicable law or interpretations thereof change so as
to permit GIAC to vote a Fund's shares in GIAC's own right or to restrict
Contractowner voting, GIAC reserves the right to do so.

      GIAC will seek voting instructions from Contractowners for the number of
shares attributable to their Contracts. Contractowners are entitled to provide
instructions if, on the applicable record date, they have allocated values to
the Investment Division which corresponds to the Fund for which a shareholder
meeting is called.

      The Contractowner will have the voting interest for the Accumulation Value
under the Contract. The number of shares held in an Investment Division for
which a Contractowner will be entitled to provide voting instructions is
determined by dividing the Contractowner's Accumulation Value in that Investment
Division by the net asset value per share of the applicable Fund.

      Each Annuitant will be entitled to the voting interest attributable to the
amounts held under his or her Certificate. The number of shares held in an
Investment Division which are attributable to each Annuitant is determined by
dividing the amounts held under a Certificate on behalf of such Annuitant by the
net asset value per share of the applicable Fund. The voting interest
attributable to each Annuitant will generally decrease with the gradual
reduction of the amounts held under the Certificate during the Annuity Payout
Period.

      There are no voting rights with respect to the Fixed-Rate Option.

                          DISTRIBUTION OF THE CONTRACT

   
      The Contract is sold by insurance agents who are licensed by GIAC and who
are either registered representatives of GISC or of broker-dealer firms which
have entered into sales agreements with GISC and GIAC. GISC and such other
broker-dealers are members of the National Association of Securities Dealers,
Inc. In connection with the sale of the Contract, GIAC will generally pay sales
commissions to these individuals or entities which may vary but, in the
aggregate, are not anticipated to exceed an amount equal to 5.25% of each
Contract premium payment. Where permitted by state law, GIAC reserves the right
to pay additional sales or service compensation while a contract is in force
based on the value of the contract. Additional amounts may also be paid in
connection with special promotional incentives. The principal underwriter of the
Contract is GISC, located at 201 Park Avenue South, New York, New York 10003.
    

                          RIGHT TO CANCEL THE CONTRACT

      Where required by state law or regulation, the Contract will contain a
provision which permits cancellation by returning the Contract to GIAC, or to
the registered representative through whom it was purchased, within 10 days of
delivery of the Contract. Longer periods may apply in some states. The
Contractowner will then receive from GIAC, as and when required by state law or
regulation, either: (1) the total amount paid for the Contract; or (2) an amount
equal to the sum of (i) the difference between the premiums paid (including any
Contract fees or other charges) and the amounts allocated to any Investment
Divisions and the Fixed-Rate Option under the Contract, and (ii) the Surrender
Value of the Contract.

                              YEAR 2000 COMPLIANCE

      Like other financial and business organizations around the world, GIAC
could be adversely affected if the computer systems it uses internally, the
systems of its service providers, and related computer systems do not properly
process and calculate date-related information and data beginning on January 1,
2000. Many computer systems today cannot distinguish the year 2000 from the year
1900 because of the way dates were encoded and calculated in these systems. GIAC
has been actively working to deal with this problem, and expects that its
systems and others upon which it is reliant will be adapted before January 1,
2000. However, there can be no assurance that these preparations will be
successful.

                                LEGAL PROCEEDINGS

      There are no material legal proceedings pending to which the Separate
Account or GIAC is a party.

                        SERVICES TO THE SEPARATE ACCOUNT

      The Guardian Insurance & Annuity Company, Inc. ("GIAC") maintains the
books and records of The Guardian Separate Account D (the "Separate Account").
GIAC, a wholly owned subsidiary of The Guardian Life Insurance Company of
America, acts as custodian of the assets of the Separate Account. GIAC bears all
expenses incurred in the operations of the Separate Account, except the
mortality and expense risk charge and the administrative charge (as described in
the Prospectus), which are borne by the Contractowner.

      The firm of Price Waterhouse LLP, 1177 Avenue of the Americas, New York,
New York 10036 currently serves as independent accountants for GIAC and the
Separate Account.

   
      Guardian Investor Services Corporation ("GISC"), a wholly owned subsidiary
of GIAC, serves as principal underwriter for the Separate Account pursuant to a
distribution and service agreement between GIAC and GISC. The Contract is
offered continuously and is sold by GIAC insurance agents who are registered
representatives of either GISC or of other broker-dealers which have selling
agreements with GISC and GIAC. In the years 1997, 1996 and 1995, GISC received
underwriting commissions from GIAC with respect to the sales of variable annuity
contracts through the Separate Account in the amount of $1,979,926, $1,851,468
and $1,409,708, respectively.
    

                                ANNUITY PAYMENTS

      The objective of the Contract is to provide benefit payments which will
increase at a rate sufficient to maintain purchasing power at a constant level.
For this to occur, the actual net investment rate must exceed the assumed
investment rate of 4% by an amount equal to the rate of inflation. Of course, no
assurance can be made that this objective will be met. If the assumed interest
rate were to be increased, benefit payments would start at a higher level but
would increase more slowly or decrease more rapidly. Likewise, a lower assumed
interest rate would provide a lower initial payment with greater increases or
lesser decreases in subsequent Annuity Payments.

      Value of an Annuity Unit: The value of an Annuity Unit is determined
independently for each of the Variable Investment Options. For any Valuation
Period, the value of an Annuity Unit is equal to the value for the immediately
preceding Valuation Period multiplied by the annuity change factor for the
current Valuation Period. The Annuity Unit value for a Valuation Period is the
value determined as of the end of such period. The annuity change factor is
equal to the net investment factor for the same Valuation Period adjusted to
neutralize the assumed investment return used in determining the Annuity
Payments. The net investment factor is reduced by the amount of the mortality
and expense risk charge on an annual basis during the life of the Contract. The
dollar amount of any monthly payment due to an Annuitant after the first monthly
payment under a Variable Investment Option will be determined by multiplying the
number of Annuity Units attributable to such Annuitant by the value of an
Annuity Unit for the Valuation Period ending ten (10) days prior to the
Valuation Period in which the monthly payment is due.

      Determination of the First Monthly Annuity Payment: At the time Annuity
Payments begin, the amount indicated by the Contractowner to purchase an Annuity
for a Plan Participant is determined by multiplying the appropriate Variable or
Fixed Accumulation Unit Value on the Valuation Period ten (10) days before the
date the first variable or fixed Annuity Payment is due by the number of
Accumulation Units cancelled pursuant to the order specified in the Prospectus
as of the date the first Annuity Payment is due, less any applicable premium
taxes not previously deducted.

      The Contract contains tables reflecting the dollar amount of the first
monthly payment which can be purchased with each $1,000 of value accumulated
under the Contract. The amounts depend on the variable or fixed Annuity Payout
Option selected, the mortality table used under the Contract (the 1983
Individual Mortality Table a projected using Scale G) and the nearest age of the
Annuitant. The first Annuity Payment is determined by multiplying the benefit
per $1,000 of value shown in the Contract


                                       B-2
<PAGE>

tables by the number of thousands of dollars of value accumulated under the
Contract for the Annuitant.

      Determination of the Second and Subsequent Monthly Variable Annuity
Payments: The amount of the second and subsequent variable Annuity Payments is
determined by multiplying the number of Annuity Units attributable to an
Annuitant by the appropriate Annuity Unit Value as of the valuation period ten
(10) days prior to the day such payment is due. The number of Annuity Units
attributable to a particular Annuitant is determined by dividing the first
monthly variable Annuity Payment to that Annuitant by the value of the
appropriate Annuity Unit on the date of such payment. This number of Annuity
Units remains fixed during the variable Annuity Payment period, provided no
transfers among the Variable Investment Options are made. If a transfer among
the Variable Investment Options is made, the number of Annuity Units will be
adjusted accordingly.

      The assumed investment return of 4% under the Contract is the measuring
point for subsequent variable Annuity Payments. If the actual net investment
rate (on an annual basis) remains constant at 4%, the variable Annuity Payments
will remain constant. If the actual net investment rate exceeds 4%, the variable
Annuity Payment will increase at a rate equal to the amount of such excess.
Conversely, if the actual rate is less than 4%, variable Annuity Payments will
decrease.

      The second and subsequent monthly payments made under a Fixed Annuity
Payout Option will be equal to the amount of the first monthly fixed Annuity
Payment (described above).

                                PERFORMANCE DATA

   
      The tables below provide performance results for each of the Separate
Account's Investment Divisions through December 31, 1997. The results shown in
this section are not an estimate or guarantee of future investment performance,
and do not represent the actual experience of amounts invested by a particular
Contractowner. Moreover, the performance information for each Investment
Division reflects the investment experience of its underlying Funds for periods
prior to the commencement of operations of the Separate Account (January 16,
1990) if the Funds existed prior to such date. Such results were calculated by
applying all Contract and Separate Account level charges to the historical Fund
performance results for such prior periods. During such prior periods, the Funds
were utilized as the underlying Funds for other separate accounts of GIAC which
were established in connection with the issuance of other variable contracts.
    

Average Annual Total Return Calculations

      The first section of the following table was calculated using the
standardized method prescribed by the Securities and Exchange Commission. It
illustrates each Investment Division's average annual total return over the
periods shown. The average annual total return for an Investment Division for a
specified period is determined by reference to a hypothetical $1,000 investment
that includes capital appreciation and depreciation for the stated period,
according to the following formula:

                                P(1 + T)^n = ERV

      Where:    P   =   A hypothetical purchase of $1,000 from which no sales 
                        load is deducted.
                T   =   average annual total return.
                n   =   number of years.
              ERV   =   ending redeemable value of the hypothetical $1,000 
                        purchase at the end of the period.

      Each calculation assumes that all dividends and distributions are
reinvested at net asset value on the reinvestment dates during the period, that
no transfers or additional purchase payments were made and 


                                      B-3
<PAGE>

the surrender of the Contract at the end of each period. The Investment
Division's average annual total return is the annual rate that would be
necessary to achieve the ending value of an investment kept in the Investment
Division for the period specified. The rate of return reflects all charges
assessed against a Contract and at the Separate Account level except for any
premium taxes that may be payable. The charges reflected include any applicable
contingent deferred sales charge; the mortality and expense risk charge; and a
pro-rated portion of the contract administration fee. See the Prospectus for a
detailed description of such charges.

      The second section of the table was calculated in the same manner as the
first except that no contingent deferred sales charge was deducted since it is
assumed that the Contract continues through the end of each period.

Change in Accumulation Unit Value

      The following performance information illustrates the cumulative change
and the actual annual change in Accumulation Unit values for the periods
specified for each Investment Division and is computed differently than the
standardized average annual total return information.

      An Investment Division's cumulative change in Accumulation Unit values is
the rate at which the value 


                                      B-4
<PAGE>

of an Accumulation Unit changes over the time period illustrated. The actual
annual change in Accumulation Unit values is the rate at which the value of an
Accumulation Unit changes over each 12-month period illustrated. The rates of
change in Accumulation Unit values quoted in the table reflect a deduction for
the Contract's mortality and expense risk charge. They do not reflect deductions
for any contingent deferred sales charge, contract administration fee or premium
taxes. The rates of change would be lower if these charges were included.

Calculation of Yield Quotations for the Cash Fund Investment Division

   
      The yield of the Investment Division of the Separate Account investing in
the Cash Fund represents the net change, exclusive of gains and losses realized
by the Investment Division or the Cash Fund and unrealized appreciation and
depreciation with respect to the Cash Fund's portfolio of securities, in the
value of a hypothetical pre-existing Contract that is credited with one
Accumulation Unit at the beginning of the period for which yield is determined
(the "base period"). The base period generally will be a seven-day period. The
current yield for a base period is calculated by dividing (1) the net change in
the value of the Contract for the base period (see "Accumulation Period" in the
Prospectus) by (2) the value of the Contract at the beginning of the base period
and multiplying by 365/7. Deductions from purchase payments (for example, any
applicable premium taxes) and any applicable contingent deferred sales charge
assessed at the time of withdrawal or annuitization are not reflected in the
computation of current yield of the Investment Division. The determination of
net change in Contract value reflects all deductions that are charged to a
Contractowner, in proportion to the length of the base period and the Investment
Division's average Contract size. The current annualized yield of the Cash Fund
Investment Division for the 7-day period ended December 31, 1997 was 5.24%.

      Yield also may be calculated on an effective or compound basis, which
assumes continual reinvestment by the Investment Division throughout an entire
year of net income earned by the Investment Division at the same rate as net
income is earned in the base period. The effective or compound yield for a base
period is calculated by (1) dividing (i) the net change in the value of the
Contract for the base period by (ii) the value of the Contract as of the
beginning of the base period, (2) adding 1 to the result, (3) raising the sum to
a power equal to 365 divided by the number of days in the base period, and (4)
subtracting 1 from the result. The effective annualized yield of the Cash Fund
Investment Division for the 7-day period ended December 31, 1997 was 5.38%.
    

      The current and effective yields of the Cash Fund Investment Division will
vary depending on prevailing interest rates, the operating expenses and the
quality, maturity and type of instruments held in the Cash Fund's portfolio.
Consequently, no yield quotation should be considered as representative of what
the yield of the Investment Division may be for any specified period in the
future. The yield is subject to fluctuation and is not guaranteed.

Performance Comparisons

      Advertisements and sales literature for the Separate Account's Investment
Divisions and their underlying Funds may compare their performance to other
investment vehicles and the separate accounts of other insurance companies as
reflected in performance data furnished by sources such as Lipper Analytical
Services, Inc., Morningstar, and Variable Annuity Research & Data Service, all
of which are independent services which monitor and rank the performance of
variable annuity issuers in each of the major categories of investment
objectives on an industry-wide basis. The performance analyses prepared by such
services rank issuers on the basis of total return, assuming reinvestment of
distributions, but may not take sales charges, redemption fees, or certain
expense deductions at the separate account level into consideration.

                   VALUATION OF ASSETS OF THE SEPARATE ACCOUNT

      The value of Fund shares held in each Investment Division at the time of
each valuation is the redemption value of such shares at such time. If the right
to redeem shares of a Fund has been suspended, or payment of redemption value
has been postponed for the sole purpose of computing Annuity Payments, the
shares held in the Separate Account (and corresponding Annuity Units) may be
valued at fair value as determined in good faith by GIAC's Board of Directors.

                          TRANSFERABILITY RESTRICTIONS

      Where a Contract is owned in conjunction with a retirement plan qualified
under the Internal Revenue Code of 1986, as amended ("Code") or a tax-sheltered
annuity program, and notwithstanding any other provisions of the Contract, the
Contractowner may not change the ownership of the Contract nor may the Contract
be sold, assigned or pledged as collateral for a loan or as security for the
performance of an obligation or for any other purpose to any person other than
GIAC unless the Contractowner is the trustee of an employee trust qualified
under the Code, the custodian of a custodial account treated as such, or the
employer under a qualified nontrusteed pension plan.

                 THE GUARDIAN INSURANCE & ANNUITY COMPANY, INC.

                  NOTES TO STATUTORY BASIS FINANCIAL STATEMENTS

                                December 31, 1997

Note 1 -- Organization

      The Guardian Insurance & Annuity Company, Inc. (GIAC or the Company) is a
wholly-owned subsidiary of The Guardian Life Insurance Company of America (The
Guardian). The Company, domiciled in the state of Delaware, is licensed to
conduct life and health insurance business in all fifty states and the District
of Columbia. The Company's primary business is the sale of variable deferred
annuity contracts and variable and term life insurance policies. For variable
products other than 401(k) products, contracts are sold by insurance agents who
are licensed by GIAC and are either Registered Representatives of Guardian
Investor Services Corporation (GISC) or of other broker dealer firms that have
entered into sales agreements with GIAC and GISC. The Company's general agency
distribution system is used for the sale of other products and policies.

      GISC, a wholly owned subsidiary of the Company, is a registered broker
dealer under the Securities Exchange Act of 1934 and is a registered investment
advisor under the Investment Adviser's Act of 1940. GISC is the distributor and
underwriter for GIAC's variable products, and the investment advisor to certain
mutual funds sponsored by GIAC, which are investment options for the variable
products.

      Insurance Separate Accounts: The Company has established fourteen
insurance separate accounts primarily to support the variable annuity and life
insurance products it offers. The majority of the separate accounts are unit
investment trusts registered under the Investment Company Act of 1940. Proceeds
from the sale of variable products are invested through these separate accounts
in certain mutual funds specified by the contractholders. Of these separate
accounts the Company maintains two separate accounts whose sole purpose is to
fund certain employee benefit plans of The Guardian.

      The assets and liabilities of the separate accounts are clearly identified
and distinct from the other assets and liabilities of the Company. The assets of
the separate accounts will not be charged with any liabilities arising out of
any other business of the Company. However, the obligations of the separate
accounts, including the promise to make annuity and death benefit payments,
remain obligations of the Company. Assets and liabilities of the separate
accounts are stated primarily at the market value of the underlying investments
and corresponding contractholders obligations. The amounts provided by the
Company to establish separate account investment portfolios (seed money) are not
included in separate account liabilities.

Note 2 -- Summary of Significant Accounting Policies

      Basis of presentation of financial statements: The financial statements
have been prepared on a statutory basis of accounting that is prescribed or
permitted by the Insurance Department of the State of Delaware which is a
comprehensive basis of accounting other than generally accepted accounting
principles (GAAP).

      Financial statements prepared on a statutory basis vary from financial
statements prepared on a GAAP basis because: (1) the costs relating to acquiring
business, principally commissions and certain policy issue expenses, are charged
to income in the year incurred, whereas on a GAAP basis they would be recorded
as assets and amortized over the future periods to be benefited; (2) life
insurance and annuity reserves are based on statutory mortality and interest
requirements, without consideration of withdrawals, whereas on GAAP basis they
are on anticipated Company experience for lapses, mortality and investment
yield; (3) life insurance enterprises are required to establish a formula-based
asset valuation reserve (AVR) by a direct charge to surplus to offset potential
investment losses; under GAAP, provisions for investments are established as
needed through a charge to income; (4) realized gains and losses resulting from
changes in interest rates on fixed income investments are deferred in the
interest maintenance reserve (IMR) and amortized into investment income over the
remaining life of the investment sold; for GAAP, such gains and losses are
recognized in income at the time of sale; (5) bonds are carried principally at
amortized cost for statutory reporting and at market value for GAAP; (6) annuity
and certain insurance premiums are recognized as premium income, whereas for
GAAP they are recognized as deposits; (7) deferred federal income taxes are not
provided for temporary differences between tax and book assets and liabilities
as they are under GAAP; (8) certain reinsurance transactions are accounted for
as reinsurance for statutory purposes and as financing transactions under GAAP,
and assets and liabilities are reported net of reinsurance for statutory
purposes and gross of reinsurance for GAAP.

      Use of Estimates: The preparation of financial statements of insurance
enterprises requires management to


                                      B-13
<PAGE>

                 THE GUARDIAN INSURANCE & ANNUITY COMPANY, INC.

                  NOTES TO STATUTORY BASIS FINANCIAL STATEMENTS

                               December 31, 1997

make estimates and assumptions that affect the reported amounts of assets and
liabilities at the date of the financial statements. As a provider of life
insurance and annuity products, GIAC's operating results in any given period
depend on estimates of policy reserves required to provide for future
policyholder benefits. The development of policy reserves for insurance and
investment contracts requires management to make estimates and assumptions
regarding mortality, lapse, expense and investment experience. Such estimates
are primarily based on historical experience and, in many cases, state insurance
laws that require specific mortality, morbidity, and investment assumptions to
be used by the Company. Actual results could differ from those estimates.
Management monitors actual experience, and where circumstances warrant, revises
its assumptions and the related reserve estimates.

      Valuation of investments: Investments in securities are recorded in
accordance with valuation procedures established by the National Association of
Insurance Commissioners (NAIC). Unrealized gains and losses on investments
carried at market are recorded directly to unassigned surplus. Realized gains
and losses on disposition of investments are determined by the specific
identification method. The Company has recorded in accordance with NAIC
requirements, the net gain from the operations of the separate accounts in the
operations of the general account in 1997 and 1996 instead of in surplus.

      Bonds: Bonds are valued principally at amortized cost. Mortgage backed
bonds are carried at amortized cost using the interest method considering
anticipated prepayments at the date of purchase. Significant changes in future
anticipated cash flows from the original purchase assumptions are accounted for
using the retrospective adjustment method with PSA standard prepayment rates.

      Investment in subsidiary: GIAC's investment in GISC is carried at equity
in GIAC's underlying net assets. Undistributed earnings or losses are reflected
as unrealized capital gains and losses directly in unassigned surplus. Dividends
received from GISC are recorded as investment income and amounted to $10,000,000
in 1997, $9,500,000 in 1996 and 6,700,000 in 1995.

      Short-Term Investments: Short-term investments are stated at amortized
cost and consist primarily of investments having maturities at the date of
purchase of six months or less. Market values for such investments approximate
carrying value.

      Loans on Policies: Loans on policies are stated at unpaid principal
balance. The carrying amount approximates fair value since loans on policies
have no defined maturity date and reduce the amount payable at death or at
surrender of the contract.

      Investment Reserves: In compliance with regulatory requirements, the
Company maintains the Asset Valuation Reserve (AVR) and the Interest Maintenance
Reserve (IMR). The AVR is intended to stabilize surplus against market
fluctuations in the value of equities and credit related declines in the value
of bonds. Changes in the AVR are recorded directly to unassigned surplus. The
IMR captures net after-tax realized capital gains which result from changes in
the overall level of interest rates for fixed income investments and amortizes
these net capital gains into income over the remaining stated life of the
investments sold. The Company uses the group method of calculating the IMR,
consistent with prior years. Any net negative IMR amounts are treated as a
non-admitted asset.

      Contract and Policy Reserves: Fixed deferred reserves represent the fund
balance left to accumulate at interest under fixed annuity contracts that were
offered directly by the Company, a fixed rate option that is offered to variable
annuity contractowners and a single premium deferred annuity that is offered by
the Company. The Company no longer offers the fixed annuity contracts.

      The estimated fair value of contractholder account balances within the
fixed deferred reserves has been determined to be equivalent to carrying value
as the current offering and renewal rates are set in response to current market
conditions and are only guaranteed for one year.

      The interest rate credited on fixed annuity contracts included in fixed
deferred reserves for 1997 and 1996 was 5.75%. The interest rate credited on the
fixed rate option that is offered to certain variable annuity contractowners was
5.50% during 1997. For the fixed rate option currently issued, the issue and
renewal interest

                 THE GUARDIAN INSURANCE & ANNUITY COMPANY, INC.

                  NOTES TO STATUTORY BASIS FINANCIAL STATEMENTS

                               December 31, 1997

rates credited varies from month to month and ranged from 5.25% to 5.40% in
1997. For single premium deferred annuities the rates ranged from 5.00% to 6.00%
in 1997. Fixed immediate reserves are a liability within the general account for
those annuitants that have elected a fixed annuity payout option. The immediate
contract reserve is computed using the 1971 IAM Table and the 1983 IAM Table and
a 4% discount rate.

      The loan collateral fund reserve is the cash value of loaned variable life
policyowner account values. The reserve is credited with interest at 4% per
annum for single premium variable life policyowners, 6.5% for annual pay
variable life policyowners and 7% for other variable life policyowners.

      Non-admitted Assets: Certain assets designated as "non-admitted assets" in
accordance with rules and regulations of the Department of Insurance of the
State of Delaware are charged directly to unassigned surplus. At December 31,
1997 and 1996 non-admitted assets consisted of agents' balances and
miscellaneous receivables in the amounts of $82,380 and $123,785, respectively.

      Acquisition Costs: Commissions and other costs incurred in acquiring new
business are charged to operations as incurred.

      Premiums and Other Revenues: Premiums and annuity considerations are
recognized for funds received on variable life insurance and annuity products.
Corresponding transfers to/from separate accounts are included in the expenses.

      Revenue also includes service fees from the separate accounts consisting
of mortality and expense charges, annual administration fees, charges for the
cost of term insurance related to variable life policies and penalties for early
withdrawals. Services fees were not charged on separate account assets of
$162,522,811 and $142,722,353 at December 31, 1997 and 1996, respectively, which
represent investments in The Guardian's employee benefit plans.

      Federal Income Taxes: The provision for federal income taxes is based on
income from operations currently taxable, as well as accrued market discount on
bonds. Realized gains and losses are reported after adjustment for the
applicable federal income taxes. The taxable portion of unrealized appreciation
of the Company's separate account investments is included in operations for 1997
and 1996, and in surplus in 1995.

      Other: Certain reclassifications have been made in the amounts presented
for prior periods to conform those periods with the 1997 presentation.

Note 3 -- Federal Income Taxes

      The Company's federal income tax return is consolidated with its parent,
The Guardian. The consolidated income tax liability is allocated among the
members of the group according to a tax sharing agreement. In accordance with
the tax sharing agreement between and among the parent and participating
subsidiaries, each member of the group computes its tax provision and liability
on a separate return basis, but may, where applicable, recognize benefits of net
operating losses and capital losses utilized in the consolidated group.
Estimated payments are made between the members of the group during the year.

      A reconciliation of federal income tax expense, based on the prevailing
corporate income tax rate of 35% for 1997, 1996 and 1995 to the federal income
tax expense reflected in the accompanying financial statements is as follows:

Note 5 -- Reinsurance Ceded

      The Company enters into coinsurance, modified coinsurance and yearly
renewable term agreements with affiliated companies and outside parties to
provide for reinsurance of selected variable annuity contracts and group life
and individual life policies. Under the terms of the modified coinsurance
agreements, reserves related to the reinsurance business and corresponding
assets are held by the Company. Accordingly, policy reserves include $76,669,184
and $447,494,766 at December 31, 1997 and 1996, respectively, applicable to
policies reinsured under modified coinsurance agreements. The reinsurance
contracts do not relieve the Company of its primary obligation for policyowner
benefits. Failure of reinsurers to honor their obligations could result in
losses to the Company.

      The effect of these agreements on the components of the Company's gain
from operations in the accompanying statements of operations are as follows:

      The Company is billed by The Guardian for all compensation and related
employee benefits for those employees of The Guardian who are engaged in the
Company's business and for the Company's use of The Guardian's centralized
services and agency force. The amounts charged for these services amounted to
$60,009,449 in 1997, $41,129,644 in 1996 and $24,989,111 in 1995, and, in the
opinion of management, were considered appropriate for the services rendered.

      The company had an investment in the Guardian Real Estate Account (GREA),
which was established in 1987 under Delaware insurance law as an insurance
company separate account. GIAC had contributed capital to GREA since it was
established to provide for funds and to preserve liquidity. Effective December
19, 1997, GREA was liquidated and, as a result, $6,746,290 was returned to GIAC
in the form of capital and there was a realized gain recorded of $969,045
included in the net gain from operations of separate accounts.

      A significant portion of the Company's separate account assets is invested
in affiliated mutual funds. These funds consist of The Guardian Park Avenue
Fund, The Guardian Stock Fund, The Guardian Small Cap Stock Fund, The Guardian
Bond Fund, The Baillie Gifford International Fund, The Baillie Gifford Emerging
Markets Fund, The Guardian Baillie Gifford International Fund, The Guardian
Asset Allocation Fund, The Guardian Investment Quality Bond Fund, The Guardian
Cash Management Fund and The Guardian Cash Fund. Each of these funds has an
investment advisory agreement with GISC, except for The Baillie Gifford
International Fund, The Baillie Gifford Emerging Markets Fund and The Guardian
Baillie Gifford International Fund. The investments as of December 31, 1997 and
1996 are as follows:

                        REPORT OF INDEPENDENT ACCOUNTANTS

February 10, 1998

To the Board of Directors of
The Guardian Insurance & Annuity Company, Inc.

      We have audited the accompanying statutory basis balance sheets of The
Guardian Insurance & Annuity Company, Inc. as of December 31, 1997 and 1996, and
the related statutory basis statements of operations, of changes in common stock
and surplus and of cash flows for the three years in the period ended December
31, 1997. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

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

      As described in Note 2, these financial statements were prepared in
conformity with accounting practices prescribed or permitted by insurance
regulatory authorities (statutory basis of accounting), which is a comprehensive
basis of accounting other than generally accepted accounting principles.
Accordingly, the financial statements are not intended to represent a
presentation in accordance with generally accepted accounting principles. The
effects on the financial statements of the variances between such practices and
generally accepted accounting principles are material and are described in Note
2.

      In our report dated February 9, 1996, we expressed an opinion that the
1995 financial statements, prepared using accounting practices prescribed or
permitted by insurance regulatory authorities, were presented fairly, in all
material respects, in conformity with generally accepted accounting principles.
As described in Note 2 to these financial statements, pursuant to pronouncements
of the Financial Accounting Standards Board, financial statements of mutual life
insurance companies and their wholly owned stock insurance company subsidiaries
are no longer considered presentations in conformity with generally accepted
accounting principles. Accordingly, our present opinion on the presentation of
the 1995 financial statements, as presented herein, is different from that
expressed in our report dated February 9, 1996.

      In our opinion, the financial statements referred to above (1) do not
present fairly, in conformity with generally accepted accounting principles, the
financial position of The Guardian Insurance & Annuity Company, Inc. at December
31, 1997 and 1996, or the results of its operations or its cash flows for the
three years in the period ended December 31, 1997, because of the effects of the
variances between the statutory basis of accounting and generally accepted
accounting principles, and (2) present fairly, in all material respects, its
financial position and the results of its operations and its cash flows, in
conformity with accounting practices prescribed or permitted by insurance
regulatory authorities.

                       DISTRIBUTION AND SERVICE AGREEMENT
                                     BETWEEN
                 THE GUARDIAN INSURANCE & ANNUITY COMPANY, INC.
                                       AND
                     GUARDIAN INVESTOR SERVICES CORPORATION

     AGREEMENT, made this 23rd day of August, 1985 by and between The Guardian
Insurance & Annuity Company, Inc. ("GIAC"), a Delaware corporation, and Guardian
Investor Services Corporation (the "Distributor"), a New York corporation, both
corporations being wholly-owned subsidiaries of The Guardian Life Insurance
Company of America and each corporation having its principal office located at
201 Park Avenue South, New York, New York 10003.

     WHEREAS, GIAC is engaged in, among other things, the issuance and sale of
variable contracts (the "Contracts") which are funded by separate accounts
organized by GIAC and registered with the Securities and Exchange Commission
("SEC") under the Securities Act of 1933 and the Investment Company Act of 1940;

     WHEREAS, Distributor is duly registered with the SEC as a broker-dealer
under the Securities Exchange Act of 1934 and is a member in good standing of
the National Association of Securities Dealers, Inc. ("NASD");

     WHEREAS, the Contracts may be sold to the public only by persons who are
insurance agents duly licensed by GIAC and one or more states of the United
States and the District of Columbia and who are also registered representatives
of the Distributor or of certain designated persons, as more fully described
herein; 
<PAGE>

     WHEREAS, GIAC and the Distributor desire to enter into an agreement,
pursuant to which the Distributor will distribute and act as the principal
underwriter for the sale of the Contracts and will select, train, license and
supervise the activities of all persons associated with it, all as more
particularly described herein.

     NOW, THEREFORE, IT IS MUTUALLY AGREED AS FOLLOWS:

     1. GIAC hereby appoints the Distributor and the Distributor agrees to act
as the distributor and as the principal underwriter for the sale of the
Contracts which may be sold to the public only by persons who are licensed
insurance agents of GIAC and registered representatives of the Distributor or
certain designated persons as set forth in paragraph 5 herein.

     2. Applications for the Contracts shall be solicited only by
representatives duly and appropriately licensed or otherwise qualified for the
sale of such Contracts in each state or other jurisdiction. GIAC shall undertake
to appoint Distributor's qualified representatives as life insurance agents of
GIAC. Completed applications for Contracts shall be transmitted directly to GIAC
for acceptance or rejection in accordance with underwriting rules established by
GIAC. Initial premium payments under the Contracts shall be made by check
payable to GIAC and shall be held at all times by Distributor or its
representatives in a fiduciary capacity and remitted promptly to GIAC. Anything
in this Agreement to the

                                       -2-
<PAGE>

contrary notwithstanding, GIAC retains the ultimate right to control the sale of
the Contracts and to appoint and discharge life insurance agents of GIAC. The
Distributor shall be held to the exercise of reasonable care in carrying out the
provisions of this Agreement.

     3. Upon request, Distributor will furnish GIAC, in writing, a list of those
agents who have become so qualified and the dates of such qualifications as well
as a list of those agents who are not selected or who have failed to qualify.
Notwithstanding the ultimate right of GIAC to appoint and discharge agents, in
the event an agent who has qualified fails or refuses to submit to the
supervision of the Distributor in accordance with this Agreement, or otherwise
fails to comply with the rules and standards imposed by the Distributor on its
registered representatives, the Distributor will certify such fact to GIAC and
will immediately notify the agent that such agent is no longer authorized to
sell the Contracts and the Distributor and GIAC will take whatever additional
action may be necessary to terminate the sales activities of the agent relating
to the Contracts.

     4. Prior to permitting any agent to sell the Contracts, GIAC, the
Distributor and the agent will enter into an agreement pursuant to which the
agent will acknowledge that he will be a registered representative of the
Distributor in connection with the agent's securities activities with respect to
the Contracts, that such activities would be under the supervision of the
Distributor

                                       -3-
<PAGE>

and any supervisor designated by the Distributor, and that the agent's right to
continue to sell the Contracts is subject to his continued compliance with such
agreement and the rules and procedures established by the Distributor for
compliance with applicable federal, state and NASD requirements.

     5. Distributor is authorized to enter into separate written agreements, on
such terms and conditions not inconsistent with this Agreement, with one or more
organizations which agree to participate in the distribution of the Contracts.
Such organization (hereafter "Broker") shall be both registered as a
broker-dealer under the Securities Exchange Act of 1934 and a member of the
NASD. Broker and its agents or representatives soliciting applications for
Contracts shall be duly and appropriately licensed, registered or otherwise
qualified for the sale of such Contracts under the insurance laws and any
applicable blue-sky laws of each state or other jurisdiction in which GIAC is
licensed to sell the Contracts.

     6. Applications for Contracts solicited by such Broker through its agents
or representatives shall be transmitted directly to GIAC, and if received by
Distributor, shall be forwarded to GIAC. All payments under the Contracts shall
be made by check to GIAC and, if received by Distributor, shall be held at all
times in a fiduciary capacity and remitted promptly to GIAC. All such payments
will be the property of GIAC.

                                       -4-
<PAGE>

     7. GIAC wishes to ensure that Contracts sold by Distributor will be issued
to purchasers for whom the Contracts will be suitable. Distributor shall take
reasonable steps to ensure that the various representatives appointed by it
shall not make recommendations to an applicant to purchase a Contract in the
absence of reasonable grounds to believe that the purchase of the Contract is
suitable for such applicant. While not limited to the following, a determination
of suitability shall be based on information furnished to a representative after
reasonable inquiry of such applicant concerning the applicant's insurance and
investment objectives, financial situation and needs, and the likelihood that
the applicant will continue to make any premium payments contemplated by the
Contracts.

     8. GIAC shall have the responsibility for furnishing to Distributor and its
representatives sales promotion materials and individual sales proposals related
to the sale of the Contracts. Distributor shall not use any such materials that
have not been approved by GIAC.

     9. GIAC shall arrange for the payment of commissions directly to those
registered representatives of Distributor who are entitled thereto in connection
with the sale of the Contracts on behalf of Distributor, in the amounts and on
such terms and conditions as GIAC and Distributor shall determine; provided that
such terms, conditions and commissions shall be as are set forth in or


                                       -5-
<PAGE>

as are not inconsistent with the Prospectus included as part of the Registration
Statement for the Contracts and effective under the Securities Act of 1933.

     10. GIAC shall arrange for the payment of commissions directly to those
Brokers who sell Contracts under agreements entered into pursuant to paragraph 5
hereof, in amounts as may be agreed to by GIAC and specified in such written
agreements.

     11. GIAC shall pay to Distributor underwriting income amounting to 0.35% of
variable annuity sales and 1.00% of single premium variable life sales made by
registered representatives of the Distributor as reimbursement for the costs and
expenses incurred by Distributor in furnishing or obtaining the services,
materials and supplies required by the terms of this Agreement in the initial
sales efforts and the continuing obligations hereunder.

     12. Distributor assumes full responsibility for the securities activities
of all persons associated with it relating to the offer and sale of the
Contracts.

     13. Distributor shall have the responsibility for maintaining the records
of its representatives licensed, registered and otherwise qualified to sell the
Contracts. Distributor shall maintain such other records as are required of it
by applicable laws and regulations. The books, accounts and records of GIAC, the
Account and


                                       -6-
<PAGE>

Distributor shall be maintained so as to clearly and accurately disclose the
nature and details of the transactions. All records maintained by GIAC in
connection with this Agreement shall be maintained and held by GIAC on behalf
of, and as agent for, the Distributor and such books and records will at all
times be subject to inspection by authorized representatives of the SEC and
NASD. The Distributor shall keep confidential any information obtained pursuant
to this Agreement and shall disclose such information only if GIAC has
authorized such disclosure or if such disclosure is expressly required by
applicable federal or state regulatory authorities.

     14. This Agreement may not be assigned by GIAC or the Distributor except by
prior written consent of the parties and shall continue from year to year,
subject to termination by either party on 60 days' written notice to the other
party, except that in the event Distributor shall cease to be a registered
broker-dealer under the Securities Exchange Act of 1934, this Agreement shall
terminate immediately.

     15. This Agreement shall be subject to the provisions of the Investment
Company Act of 1940 and the Securities Exchange Act of 1934 and to the rules and
regulations promulgated thereunder and to the applicable rules and regulations
of the NASD, and the terms hereof shall be interpreted and construed in
accordance therewith.

     16. If any provision of this Agreement shall be held or made invalid by a
court decision, statute, rule or


                                      -7-
<PAGE>

otherwise, the remainder of this Agreement shall not be affected thereby.

     17. This Agreement shall be construed and enforced in accordance with and
governed by the laws of the State of New York.

     18. This Agreement supersedes in all respects any other agreements between
the parties hereto relating to the distribution and service of the Contracts.

   LAWS

Broker-Dealer shall fully comply with the requirements of the NASD and of the
Securities Exchange Act of 1934 and all other applicable federal or state laws
and will establish such rules and procedures as may be necessary to cause
diligent supervision of the securities activities of the Representatives. Upon
request by GISC, Broker-Dealer shall furnish such appropriate records as may be
necessary to establish such diligent supervision.

H. NOTICE OF REPRESENTATIVE'S NONCOMPLIANCE

In the event a Representative fails or refuses to submit to supervision of
Broker-Dealer or otherwise fails to meet the rules and standards imposed by
Broker-Dealer on its Representatives, Broker-Dealer shall certify such fact to
GIAC and shall immediately notify such Representative that he or she is no
longer authorized to sell the Plans, and Broker-Dealer shall take whatever
additional action may be necessary to terminate the sales activities of such
Representative relating to the Plans.

I. PROSPECTUSES, SALES PROMOTION MATERIAL AND ADVERTISING

Broker-Dealer shall be provided, without any expense to Broker-Dealer, with
prospectuses relating to the Plans and such other material as GISC determines
to
be necessary or desirable for use in connection with sales of the Plans. No

to the Plans shall be used by Broker-Dealer unless the specific item has been
approved in writing by GISC.

J. RIGHT OF REJECTION

Broker-Dealer and/or GIAC, each at their sole discretion, may reject any
applications or payments remitted by Representative through the Broker-Dealer
and may refund an applicant's payments to the applicant. In the event such
refunds are made, and if Representative has received compensation based on an
applicant's Payment that is refunded, Representative shall promptly repay such
compensation to the Broker-Dealer. If repayment is not promptly made, the
Broker-Dealer may, at its sole option, deduct any amounts due it from
Representative from future commissions otherwise payable to Representative.

K. ASSIGNMENT

Neither this Agreement nor any of its benefits may be assigned by Representative
without the written consent of GIAC and GISC, and any assignment of this
agreement, compensation or other benefits or obligations hereunder shall not be
valid if made without such consent.

- --------------------------------------------------------------------------------
IV.  COMPENSATION
- --------------------------------------------------------------------------------

A. SUPERVISORY FEES, SERVICE FEES AND COMMISSIONS

Supervisory and service fees payable to Broker-Dealer and commissions payable to
Representatives in connection with the Plans shall be paid by GIAC to the
person(s) entitled thereto through Broker-Dealer or as otherwise required by
law. GISC will provide Broker-Dealer with a copy of GIAC's current Dealer
Concession and Commissions Schedule. These fees and commissions will be paid as
a percentage of premiums or purchase payments (premiums and purchase payments
are hereinafter referred to collectively as "Payments") received in cash or
other legal tender and accepted by GIAC on applications obtained by the various
Representatives of the Broker-Dealer. Upon termination of this Agreement, all
compensation to the Broker-Dealer hereunder shall cease; however, Broker-Dealer
shall continue to be liable for any chargebacks pursuant to the provisions of
said Dealer Concession and Commissions Schedule or for any other amounts
advanced by or otherwise due GIAC hereunder.

B. TIME OF PAYMENT

GIAC shall pay any compensation due Broker-Dealer and Representatives of
Broker-Dealer within fifteen (15) days after the end of the calendar month in
which Payments upon which such compensation is based are accepted by GIAC.

C. AMENDMENT OF SCHEDULES

GIAC may, upon at least ten (10) days prior written notice to Broker-Dealer
change the Dealer Concession and Commissions Schedule. Any such change shall be
by written amendment of the
<PAGE>

particular schedule or schedules and shall apply to compensation due on
applications received by GIAC after the effective date of such notice.

D. PROHIBITION AGAINST REBATES

If Broker-Dealer or any Representative of Broker-Dealer shall rebate or offer to
rebate all or any part of a Payment on a policy or contract or certificate
issued by GIAC, or if Broker-Dealer or any Representative of Broker-Dealer shall
withhold any Payment on any policy or contract or certificate issued by GIAC,
the same may be grounds for termination of this Agreement by GIAC. If
Broker-Dealer or any Representative of Broker-Dealer shall at any time induce or
endeavor to induce any owner of any policy or contract issued hereunder or any
certificate holder to discontinue Payments or to relinquish any such policy or
contract or certificate except under circumstances where there is reasonable
grounds for believing the policy, contract or certificate is not suitable for
such person, any and all compensation due Broker-Dealer hereunder shall cease
and terminate.

E. INDEBTEDNESS

Nothing in this Agreement shall be construed as giving Broker-Dealer the right
to incur any indebtedness on behalf of GIAC. Broker-Dealer hereby authorizes
GIAC to set off liabilities of Broker-Dealer to GIAC against any and all amounts
otherwise payable to Broker-Dealer by GIAC.

- --------------------------------------------------------------------------------
V.   GENERAL PROVISIONS
- --------------------------------------------------------------------------------

A. WAIVER

Failure of any party to insist upon strict compliance with any of the conditions
of this Agreement shall not be construed as a waiver of any of the conditions,

any other provisions, whether or not similar, nor shall any waiver constitute a
continuing waiver.

Representatives of Broker-Dealer who are licensed pursuant to this Agreement as
GIAC agents for state insurance law purposes or who have access to funds of
GIAC, including but not limited to funds submitted with applications for the
Plans or funds being returned to owners or certificate holders, are and shall be
covered by a blanket fidelity bond, including coverage for larceny and
embezzlement, issued by a reputable bonding company. This bond shall be
maintained by Broker-Dealer at Broker-Dealer's expense. Such bond shall be, at
least, of the form, type and amount required under the NASD Rules of Fair
Practice. GIAC may require evidence, satisfactory to it, that such coverage is
in force and Broker-Dealer shall give prompt, written notice to GIAC of any
notice of cancellation or change of coverage.

Broker-Dealer assigns any proceeds received from the fidelity bonding company to
GIAC to the extent of GIAC's loss due to activities covered by the bond. If
there is any deficiency amount, whether due to a deductible or otherwise,

hereby indemnities and holds harmless GIAC from any such deficiency and from the
costs of collection thereof (including reasonable attorneys' fees).

Broker-Dealer shall not print, publish or distribute any advertisement, circular
or any document relating to the Plans or relating to GIAC unless such
advertisement, circular or document shall have been approved in writing by GIAC

<PAGE>

                               1. ANNUITY BENEFIT

Under certain conditions, the owner may direct the Company to apply a portion of
this contract's accumulation value to provide monthly annuity payments for a
plan participant. (See page 11 for the definitions of the terms "plan" and
"participant.") Annuity payments for a participant will begin on the annuity
commencement date for such participant as stated by the owner, if:

o     this contract is in force on that date; and

o     the participant is living and is between the ages of 50 and 85 (unless the
      Company agrees otherwise) on that date.

At the time annuity payments begin, the Company will determine the amount of
each monthly annuity payment. This amount will be calculated by applying the
amount applied for a participant as stated by the owner, less any applicable
state premium taxes, under Option V-2 of Variable Annuity Payout Options, unless
another option is elected. The amounts of the payments will vary according to
the annuitant's age. Under Option V-2, payments are guaranteed for a period of
10 years. See the "Payment of Contract Proceeds" section for an explanation of
how annuity payments are determined.

The Company will issue a certificate to the owner for delivery to each
participant when an annuity is provided for such participant. Each such
certificate will set forth the amount and terms of the annuity payments and any
other benefits to which the participant may be entitled under this contract.

                                    2. OWNER

Owner

The owner is named in the application. The owner alone has the right to receive
all benefits and exercise all rights this contract grants or the Company allows.

Nontransferability of Ownership

If this contract is issued in conjunction with a retirement plan qualified under
the Internal Revenue Code, the owner may not:

o     change the ownership;

o     sell or assign this contract;

o     pledge this contract as collateral for a loan or as security for the
      performance of an obligation or for any other purpose to any person other
      than the Company, unless the owner is:

      o     the trustee of an employee trust qualified under the Internal
            Revenue Code;

      o     the custodian of a custodial account treated as such; or

      o     the employer under a qualified nontrusteed pension plan.

Assignment

No assignment will bind the Company unless the original, or a copy in a form
satisfactory to the Company, is filed at the Customer Service Office. Afterward,
the rights of any owner will be subject to the assignment. The entire contract
will be subject to the assignment. The Company will rely solely on the
assignee's statement as to the amount of the assignee's interest. The Company
will not be responsible for the validity of any assignment. Unless otherwise
provided, the assignee may exercise all rights this contract grants except:

o     the right to change the beneficiary; and

o     the right to elect an annuity payout option.

                              3. PREMIUM PAYMENTS

Under this contract, the owner may make flexible premium payments to the Company
in accordance with the provisions of the plan. All premium payments are payable
at the Company's Customer Service Office.

The minimum amount of the initial premium payment is $5,000. While this contract
is in force, the Company will accept additional flexible premium payments of at
least $500. Subsequent payments in excess of $100,000 in any one contract year
are acceptable only with the written consent of the Company.

Allocation of Net Premiums

A net premium is equal to the premium paid less any applicable state premium
taxes. Subject to the conditions described below, the Company will allocate the
net premiums to the contract's allocation options, which consist of the Fixed
Rate Option and the following variable investment options:

o     the investment divisions of The Guardian Separate Account D (as described
      below); and

o     The Guardian Real Estate Account (as described below).

Such allocation will be based on the allocation percentages designated in the
application, or as subsequently changed by the owner in a written notice
acceptable to the Company and received by the Company at its Customer Service
Office prior to the date of the allocation. The value of the contract and any
net premiums paid may not be invested in more than four allocation options at
any time; that is, such value or net premiums may not be transferred or
allocated to more than four variable investment options or three variable
investment options and the Fixed Rate Option at any time.

Net premiums will be applied to provide accumulation units (see "Accumulation
Units" provision).

4. SEPARATE ACCOUNTS

The Guardian Separate Account D and The Guardian Real Estate Account

This contract is funded by two separate investment accounts established by the
Company under the laws of the state of Delaware. These separate accounts are
subject to the laws of the jurisdiction in which this contract is delivered.
These separate accounts are:

o     The Guardian Separate Account D (Account D); and

o     The Guardian Real Estate Account (the RE Account).

Account D is registered as a unit investment trust with the Securities and
Exchange Commission (SEC) under the Investment Company Act of 1940, and its
units are registered under the Securities Act of 1933 (1933 Act). The RE Account
itself is not an investment company, but its interests are registered with the
SEC under the 1933 Act. Each separate account is treated as a division of the
Company. Account D is used to provide values and benefits for variable annuities
only. The Company owns the assets in both separate accounts. The assets in
Account D and the RE Account are kept separate from:

o     each other;

o     the Company's general investment account; and

o     the Company's other separate accounts.

Assets equal to the reserves and liabilities of Account D or the RE Account will
not be charged with liabilities that arise from any other business the Company
may conduct. The Company may transfer assets in excess of the reserves and
liabilities of Account D or the RE Account to the general investment account.
Income and realized and unrealized gains and losses from assets in Account D or
the RE Account are credited to or charged against the applicable separate
account without regard to income, gain, or loss in the Company's other
investment accounts.

Investment Divisions

Account D consists of several investment divisions. Each investment division of
Account D invests in shares of a mutual fund. Each mutual fund is managed by an
investment adviser registered under the Investment Advisers Act of 1940.

The investment divisions available on the issue date are listed in the then
current prospectus for Account D as it relates to this contract. Each mutual
fund is more fully described in a separate prospectus for each fund.

Rights Reserved by the Company

The Company reserves the right to take certain actions deemed to be in the
best interest of the owner and when permitted by applicable law. These
actions are:

o     to deregister Account D under the Investment Company Act of 1940;

o     to operate Account D as a management investment company or any other form
      permitted by law;

o     to combine any two or more separate accounts or investment divisions
      within Account D;

o     to transfer assets determined by the Company to be assigned to the class
      of contracts to which the contracts belong from Account D or the RE
      Account to another separate account by withdrawing the same percentage of
      each investment in Account D or the RE Account with appropriate
      adjustments to avoid odd lots and fractions;

o     to substitute shares of any fund offered under this contract with shares
      of another fund offered under this contract if, in the judgment of the
      Company, further investment in such shares is no longer appropriate. Such
      change may be subject to the approval of the SEC, the Delaware Insurance
      Department and other state or federal regulatory authorities;

o     to add to, eliminate, or suspend the owner's ability to allocate premium
      payments or transfer amounts to any investment division within Account D
      and/or the Real Estate Account; and

o     to modify this contract as necessary to prevent the owner from being
      considered the owner of the assets of Account D, the RE Account, or the
      Fixed Rate Option, and thereby subject to federal or state income taxation
      on gains under the contract.

Change in Investment Objective or Policy

The Company will notify the owner of any material change in an investment policy
or objective of any mutual fund invested in by an investment division to which
part of this contract's accumulation value is allocated. Details of any such
change will be filed with any regulatory authority where required and will be
subject to any required approval.

                            5. THE FIXED RATE OPTION

The owner may allocate all or part of any net premiums to the Fixed Rate Option.
The Company will credit interest on the portion of net premiums applied to and
any amounts transferred to the Fixed Rate Option. Interest will accrue daily at
a minimum guaranteed annual rate of 3.5%. At the discretion of the Company, an
interest rate in excess of the minimum guaranteed rate may be credited. The
Company will provide notice of the applicable interest rates in the annual
report to the owner and upon request.

Any portion of a net premium allocated to the Fixed Rate Option on the issue
date will earn interest at the then current rate as set by the Company. This
interest rate will be guaranteed until the next contract anniversary.

After the issue date, any portion of net premiums applied to and any amounts
transferred into the Fixed Rate Option will earn interest at the then current
rate set by the Company. This rate will be guaranteed for the remainder of the
contract year, until the next contract anniversary.

                                   [SPECIMEN]
<PAGE>

THE FIXED RATE OPTION--cont'd.

On the contract anniversary, any portion of the accumulation value attributed to
the Fixed Rate Option will earn interest at the then current rate set by the
Company. This rate will be guaranteed until the next contract anniversary.

If, on any contract anniversary the interest rate the Company sets for the Fixed
Rate Option is more than 3 percentage points lower than the rate set for the
immediately preceding contract year, the owner may withdraw all or a portion of
the accumulation value held in the Fixed Rate Option for at least one contract
year without that amount being subject to a contingent deferred sales charge.
The Company must receive proper written request for such withdrawal at its
Customer Service Office within 60 days of such contract anniversary.

                                  6. TRANSFERS

Transfers of Accumulation Value by the Owner

The owner may transfer all or a portion of the accumulation units credited under
this contract among the investment divisions of Account D, the RE Account, and
the Fixed Rate Option, subject to the following conditions:

o     Proper written request for transfer must be received by the Company at its
      Customer Service Office. Other transfer procedures permitted by the
      Company, if any, must be followed as set out in the prospectus for this
      contract.

o     Accumulation units may not be credited to or transferred into more than
      four variable investment options or to three variable investment options
      and the Fixed Rate Option at any time.

o     The transfer of accumulation units from the RE Account to a subdivision of
      Account D or to the Fixed Rate Option may only be made once each year on
      or within 30 days after a contract anniversary. The maximum amount that
      may be transferred from the RE Account each contract year is the greater
      of:

      o     33 1/3% of the accumulation value attributable to the RE Account as
            of the contract anniversary; or

      o     $10,000.

o     The transfer of accumulation units from the Fixed Rate Option to an
      investment division of Account D or to the RE Account may only be made
      once each year on or within 30 days after a contract anniversary.
      Transfers out of the Fixed Rate Option will be made in the same order as
      such amounts were allocated to the Fixed Rate Option. The maximum amount
      that may be transferred from the Fixed Rate Option each contract year is
      the greater of:

      o     33 1/3% of the portion of the accumulation value attributable to the
            Fixed Rate Option as of the contract anniversary; or

      o     $2,500.

The number of additional accumulation units credited under this contract in the
newly elected Fixed Rate Option or variable investment option(s) will be equal
to (a) divided by (b) where:

o     (a) is the value of the amount transferred; and

o     (b) is the value of an accumulation unit in the newly elected investment
      option(s) as of the end of the valuation date on which the proper written
      request for transfer is received by the Company at its Customer Service
      Office.

The Company reserves the right to limit the frequency of transfers of
accumulation units under the contract to once every 30 days and to charge for
such transfers in the future.

Transfers By An Annuitant Following His/Her Annuity Commencement Date

An annuitant receiving annuity payments under a variable annuity payout option
may transfer all or a portion of his/her annuity units (as defined in the
"Annuity Unit Values" provision) among the variable investment options. The
conditions applicable to transfers of accumulation units, as described above,
also apply to transfers made after an annuity commencement date.

However, any transfers after an annuity commencement date can be made only once
each year. Any such transfer will take effect upon the next calculation of
annuity unit values after the Company receives proper transfer instructions at
its Customer Service Office.

For transfers made after an annuity commencement date, the number of additional
annuity units credited under the newly elected variable investment option(s)
will be equal to (a) divided by (b), where:

o     (a) is the amount of the monthly variable annuity payment that is to be
      transferred as of December 31st of that year; and

o     (b) is the value of one annuity unit in the newly elected investment
      option(s) as of December 31st of that year.

After an annuity commencement date, the annuitant receiving annuity payments
under a fixed annuity payout option may not transfer into the RE Account or the
investment divisions of Account D.

Dollar Cost Averaging Transfer Option

If part of the contract's accumulation value is allocated to the investment
division investing in The Guardian Cash Fund, the owner may choose to make
monthly transfers under the Dollar Cost Averaging Transfer Option, subject to
the conditions described below.

Under this option, an amount specified by the owner will be automatically
transferred out of The Guardian Cash Fund and into the Fixed Rate Option or the
variable investment option(s)


                                     Page 5

TRANSFERS--cont'd.

elected by the owner on a monthly basis. The owner may choose to have monthly
transfers made for durations of 12, 24, or 36 months.

The following conditions apply to the Dollar Cost Averaging Transfer Option:

o     An owner may elect this option on the issue date only if the initial
      premium is at least:

      o     $10,000 and the owner chooses to make monthly transfers for a 12
            month period; or

      o     $20,000 and the owner chooses to make monthly transfers for a 24
            month or 36 month period.

o     An owner may elect this option after the issue date only if the contract
      has a minimum accumulation value at the time the option is elected:

      o     If the owner chooses to make monthly transfers for a 12 month
            period, the contract's accumulation value must be at least $10,000.

      o     If the owner chooses to make monthly transfers for a 24 month or 36
            month period, the contract's accumulation value must be at least
            $20,000.

o     The minimum amount which may be transferred into the Fixed Rate Option
      and/or each variable investment option is $100.

o     Money may not be transferred into more than three other variable
      investment options or two other variable investment options and the Fixed
      Rate Option at any time.

The transfer amount(s) selected by the owner multiplied by the duration selected
may not exceed the accumulation value of The Guardian Cash Fund at the time the
option is exercised. Transfers will be made on each monthly anniversary, or on
the next business day if such anniversary is on a weekend or holiday.

The Dollar Cost Averaging Transfer Option will terminate if:

o     this contract is surrendered;

o     the requested number of transfers has been made;

o     the accumulation value in The Guardian Cash Fund is insufficient to make a
      monthly transfer; or

o     the Company receives proper written request from the owner to cancel the
      option. Such request must be received at the Company's Customer Service
      Office at least 3 business days before the next monthly anniversary in
      order to cancel the transfer scheduled to take effect on such anniversary.

After the issue date, in order to initiate or effect any change under the Dollar
Cost Averaging Transfer Option, or to reinstate such option if it has
terminated, the owner must properly complete an enrollment form and submit it to
the Company's Customer Service Office. Such form must be received by the Company
at least 3 business days before the monthly anniversary on which such first
transfer will be made.

                             7. ACCUMULATION VALUE

Accumulation Units

An accumulation unit is a measurement used to determine the value of the owner's
interest under this contract while the contract is in force. As each participant
reaches his/her annuity commencement date, the accumulation value under the
contract is reduced by the value of the accumulation units used by the owner to
purchase an annuity for such participant. The number of accumulation units
purchased in each designated variable investment option or the Fixed Rate Option
will be determined by multiplying (a) by (b), then dividing the result by (c),
where:

o     (a) is the net premium;

o     (b) is the percentage to be allocated to the specified variable investment
      option or the Fixed Rate Option; and

o     (c) is the value of an accumulation unit for the specified variable
      investment option or the Fixed Rate Option as of the valuation period
      during which the premium is received at the Company's Customer Service
      Office.

The value of each variable accumulation unit will depend on the investment
experience of the variable investment options selected. Thus this value may
increase or decrease and may vary from one valuation period to the next.

Accumulation Unit Value for Account D and the RE Account

The value of a variable accumulation unit for each investment division of
Account D and for the RE Account was established at $10.00 as of the date
operations began for that division or began for the RE Account. The accumulation
unit value for any valuation period thereafter is (a) multiplied by (b), where:

o     (a)is the variable accumulation unit value for the immediately preceding
      valuation period; and

o     (b) is the net investment factor, as described below, for the current
      valuation period.

Accumulation Unit Value for the Fixed Rate Option

The value of accumulation units for the Fixed Rate Option was established at
$10.00 as of the date operations began for that option. Thereafter, it will
increase daily at a rate of interest to be determined from time to time by the
Company, but which is guaranteed to be no less than 3.5% annually.

Net Investment Factor

The Company assesses a daily charge of .00003169 of the value of the assets
allocated to each of the investment divisions of Account D and to the RE Account
for its assumption of mortality and expense risks. This mortality and expense
charge is used in determining the net investment factor for each investment
division of Account D and for the RE Account. On an annual basis, the charge is
equal to 1.15% of the value of the assets allocated to these variable investment
options.

                                   [SPECIMEN]
<PAGE>

ACCUMULATION VALUE - cont'd.

The net investment factor is used to calculate the value of an accumulation unit
in an investment division of Account D or in the RE Account for a valuation
period. The net investment factor is determined by dividing the sum of (a) and
(b) by (c), and subtracting (d) from the result, where:

      o     (a) is the net asset value of a fund share held in Account D for the
            applicable investment division or any interest held in the RE
            Account, determined as of the end of the then current valuation
            period;

      o     (b) is the per share or per interest amount of any dividend and
            other distributions made by the fund or the RE Account during the
            current valuation period;

      o     (c) is the net asset value of the particular fund share or interest
            in the RE Account determined as of the end of the immediately
            preceding valuation period;

      o     (d) is any applicable state premium taxes and the mortality and
            expense charge.

The net investment factor may be less than 1.00 since it is related to the
investment experience of a separate account.

Accumulation Value

The value of all the accumulation units credited to this contract is the
accumulation value. The accumulation value within any particular variable
investment option or the Fixed Rate Option is determined by multiplying (a) by
(b), where:

      o     (a) is the number of accumulation units credited to the contract for
            that particular variable investment option or the Fixed Rate Option;
            and

      o     (b) is the applicable current accumulation unit value.

On each participant's annuity commencement date, the accumulation value of this
contract will be reduced by that portion of the accumulation value applied by
the owner to purchase an annuity for the participant.

                          8. SURRENDERS AND WITHDRAWALS

The owner may withdraw all or part of the accumulation value of this contract.

Surrender of Contract

The owner may surrender this contract for its then current accumulation value;
the contract will then terminate. This contract must be sent to the Company's
Customer Service Office for cancellation. 

Partial Withdrawals

Any partial withdrawals first will be taken from the investment divisions of
Account D in proportion to each investment division's accumulation value on the
date of the withdrawal. Partial withdrawals in excess of the amount taken from
the investment divisions of Account D will then be withdrawn from the RE
Account. Any remaining excess will be withdrawn from the Fixed Rate Option.
Amounts withdrawn from any variable investment option or the Fixed Rate Option
will be made in the same order in which such amounts were allocated to that
variable investment option or the Fixed Rate Option.

The total accumulation value remaining after a partial withdrawal must be at
least $1,000. If a partial withdrawal results in the total accumulation value
falling below $1,000, then the balance will be paid to the owner and the
contract will be cancelled.

The following conditions apply for both partial withdrawals and surrenders:

      o     Written request satisfactory to the Company must be received at its
            Customer Service Office prior to any surrender or withdrawal.

      o     Any withdrawal payment or surrender will be reduced by any
            applicable state premium taxes and contingent deferred sales charges
            (as described below).

      o     The amount of any withdrawal payment will be determined as of the
            valuation date on or next following the date the Company receives
            the owner's proper written request for surrender or withdrawal.

Contingent Deferred Sales Charges

A contingent deferred sales charge may be imposed on partial withdrawals or on
the surrender of the contract. The amount of any contingent deferred sales
charge will be the lesser of:

      o     6% of the total premiums paid in the 84 month period preceding the
            date of withdrawal or surrender; or

      o     6% of the amount withdrawn or surrendered.

However, in any contract year after the first, the owner may make withdrawals,
without incurring any contingent deferred sales charge, of up to 10% of the
greater of:

      o     the amount of total premiums paid during the 84 months preceding the
            date of withdrawal; or

      o     the accumulation value as of the date of the first withdrawal in
            that contract year.

The maximum amount of contingent deferred sales charges applied during the 84
months immediately preceding the date of withdrawal will never exceed 6% of the
total premiums paid during such period.

Administration Fee

On each contract anniversary the Company will deduct an administration fee of
$35 from the accumulation value of this contract. This fee will be deducted from
each investment division of Account D, from the RE Account and from the Fixed
Rate Option in proportion to the percentage of the accumulation value in Account
D, the RE Account, and the Fixed Rate Option on that date. If this contract is
surrendered on a date other than on a contract anniversary, the Company will
deduct the administration fee on the date of surrender.

                         9. PAYMENT OF CONTRACT PROCEEDS

Following his/her annuity commencement date, each participant under this
contract will be referred to as an "annuitant".

Payment

When directed by the owner, the Company will make monthly variable annuity
payments to the annuitant under Variable Annuity Payout Option V-2, as stated in
the "Annuity Benefit" provision or, if elected, one of the other annuity payout
options. Payment of any annuity benefit may be made under either a fixed or
variable annuity payout option or a combination of both. If annuity payout
option F-3 or V-3 is chosen, the annuitant must also select a joint annuitant.

o     The amount of the first annuity payment will be based on the table for the
      annuity payout option elected.

o     The amount of any fixed annuity payments will not be less than the
      corresponding minimum amount based on the tables for the fixed annuity
      payout options, with interest compounded each year at 4%.

o     The amount of any variable annuity payments after the first will increase
      or decrease according to the value of the variable annuity units, which
      reflect the investment experience of the variable investment option(s)
      elected. Any such payments will be based on an assumed investment return
      of 4% per year.

o     All monthly annuity payments are based on:

      o     the age of the annuitant at the birthday nearest the date payments
            are to begin; and

      o     the annuity payout option elected.

The annuity payout option tables are based on the blended 1983 Individual
Annuity Mortality Table a projected under Scale G factors.

Change of Beneficiary

The annuitant may changes beneficiary designated to receive benefits under
annuity payout options V-2 and F-2. Any request for change must be in a written
form satisfactory to the Company. The change will take effect on the date the
request is signed, whether or not the annuitant is living when the Company
receives the request at its Customer Service Office. However, the change will
not apply to any payments made or actions taken by the Company before the
request is received.

Contingent Beneficiary

A numbered sequence may be used to name contingent beneficiaries for annuity
payout options V-2 and F-2. The beneficiary is the living person(s) designated
by the lowest number in the sequence.

Variable Annuity Payout Options Available

Option V.1 - Life Annuity without Guaranteed Period 

The Company will make monthly variable annuity payments for the lifetime of the
annuitant. The amount of the first monthly payment will be based on the Option
V-1 table.

Option V-2 - Life Annuity with 10 Year Guaranteed Period

The Company will make monthly variable annuity payments during the lifetime of
the annuitant. The amount of the first monthly payment will be based on the
Option V2 table.

Payments are guaranteed for a period of 10 years. If the annuitant dies sooner,
payments will be made during the remaining period to the beneficiary designated
by the owner. The beneficiary may elect to be paid the commuted value of the
current dollar amount of the then remaining number of variable annuity payments.
If the beneficiary dies while receiving such payments, the commuted value of the
current dollar amount of the remaining number of variable annuity payments will
be paid in one sum to the beneficiary's estate.

If any designated beneficiary dies before the annuitant, the interest of that
beneficiary shall pass to the designated surviving beneficiary. If more than one
beneficiary survives the annuitant, such interest shall pass to the surviving
beneficiaries in proportion to their respective interest, unless otherwise
previously specified by the owner. If no designated beneficiary survives the
annuitant, and no other designation is provided, the benefit provided under this
annuity payout option shall be paid in one sum to the annuitant's estate.

Option V-3 - Joint and Survivor Annuity

The Company will make monthly variable annuity payments while the annuitant and
the joint annuitant are living. When an annuitant dies, two-thirds of the number
of annuity units in effect while both were living will continue for the lifetime
of the survivor. The amount of the first variable annuity payment will be based
on the Option V-3 table.

Fixed Annuity Payout Options Available

Option F-1 - Life Annuity without Guaranteed Period

The Company will make monthly fixed annuity payments for the lifetime of the
annuitant.

Option F-2 - Life Annuity with 10 Year Guaranteed Annuity Period
                    
The Company will make monthly fixed annuity payments during the lifetime of the
annuitant. Payments are guaranteed for a period of 10 years. If the annuitant
dies sooner, payments will be made during the remaining period to the
beneficiary designated by the owner. The beneficiary may elect to be paid the
present value of the current dollar amount of the then remaining number of fixed
annuity payments. If the beneficiary dies while receiving such payments, the
present value of the current dollar amount of the remaining number of fixed
annuity payments will be paid in one sum to the beneficiary's estate.
<PAGE>

PAYMENT OF CONTRACT PROCEEDS - cont'd.

If any designated beneficiary dies before the annuitant, the interest of that
beneficiary shall pass to the designated surviving beneficiary. If more than one
beneficiary survives the annuitant, such interest shall pass to the surviving
beneficiaries in proportion to their respective interest, unless otherwise
previously specified by the owner. If no designated beneficiary survives the
annuitant, and no other designation is provided, the benefit provided under this
annuity payout option shall be paid in one sum to the annuitant's estate.

Option F-3 - Joint and Survivor Annuity

The Company will make monthly fixed payments while the annuitant and the joint
annuitant are living. When an annuitant dies, the Company will continue to pay,
for the lifetime of the survivor, two-thirds of the amount of the payment in
effect while both were living.

Determination of First Annuity Payment

The tables below indicate the dollar amount of the first monthly annuity payment
which can be purchased with each $1,000 of the portion of the accumulation value
applied by the owner to purchase an annuity for a participant. The first annuity
payment is determined by multiplying (a) by (b), where:

      o     (a) is the amount shown in the applicable table for the annuitant's
            age; and

      o     (b) is the number of thousands of dollars of accumulation value.

The dollar amount of the first monthly annuity payment purchased for ages not
shown in the tables are available upon request.

Annuity Unit Values

For variable annuity payout options, the portion of the accumulation value
stated by the owner will be applied to purchase annuity units. Annuity units are
used to determine the amount of each variable annuity payment after the first.

The value of an annuity unit is determined independently for each investment
division of Account D and for the RE Account The dollar value of variable
annuity units may increase or decrease depending upon the investment experience
of the investment option(s) elected.

The value of an annuity unit in each investment division of Account D and in the
RE Account was established at $1.00 on the date operations began for each such
variable investment option. The value of an annuity unit at the end of any
subsequent valuation period is equal to (a) multiplied by (b), where:

      o     (a) is the annuity unit value on the immediately preceding valuation
            period; and

      o     (b) is the annuity change factor for the current valuation period.

The annuity change factor is equal to the net investment factor (as described in
the "Net Investment Factor" provision) for the same valuation period adjusted to
recognize the assumed investment return of 4% per year used in determining the
amounts of variable annuity payments.

The valuation of all assets in Account D and the RE Account will be determined
in accordance with all applicable laws and regulations.

Determination of Variable Annuity Payments After the First

The amounts of variable annuity payments made after the first are determined by
multiplying (a) by (b), where:

      o     (a) is the number of annuity units in each investment division of
            Account D and in the RE Account; and

      o     (b) is the appropriate annuity unit value as of the valuation date
            10 days prior to the date the variable annuity payment is due.

The number of annuity units under this contract is determined by dividing (a) by
(b), where:

      o     (a) is the amount of the first monthly variable annuity payment for
            each investment division of Account D and for the RE Account; and

      o     (b) is the value of the appropriate annuity unit on the date the
            first variable annuity payment is made.

The number of annuity units remains fixed during the annuity payment period,
provided no transfers among variable investment options are made.

The Company guarantees that the dollar amount of each variable annuity payment
after the first will not be adversely affected by:

      o     the actual administration expenses it incurs; or

      o     variations in mortality experience from the mortality assumptions
            upon which the first payment is based.

Annuity Payout Options: General Provisions

      o     At least $2,000 must be applied under an annuity payout option for
            any annuitant. Proceeds of a smaller amount will be paid in one sum.

      o     If monthly annuity payments are or become $20 or less, the Company
            reserves the right to change the frequency of payment.

      o     While an annuitant is receiving annuity payments and subject to the
            Company's consent, the annuitant may change the frequency of the
            annuity payments being made. A written request for such change, in a
            form satisfactory to the Company, must be received at the Customer
            Service Office. The change will take effect upon receipt of the
            written request.

      o     The Company requires satisfactory proof of the age of the annuitant
            on the date annuity payments begin.

      o     Except with the consent of the Company, the annuity payout options
            will not be available with respect to any part of the proceeds
            payable to an assignee or to other than a natural person entitled to
            receive proceeds.

      o     The annuitant does not have the right to advance or assign payments
            made under an annuity payout option.

      o     The annuitant cannot make any change in the manner of payout, except
            as provided in the election.

      o     To the extent permitted by law, the payments made under an annuity
            payout option will not be subject to encumbrance, or to the claims
            of creditors or legal process.

                        AMENDMENT OF CONTRACT PROVISIONS

This rider is attached to and made part of the Contract. This rider is subject
to all of the applicable provisions of the Contract.

                              The Fixed Rate Option

Subject to the conditions stated in this rider, the Owner may allocate all or
part of any net premium(s) to the Fixed Rate Option. If this Contract is a
single premium payment Contract, then any instructions to allocate the net
premium to the Fixed Rate Option must be made on or before the issue date of
this Contract. If any part of a net premium is allocated to the Fixed Rate
Option, the balance may be allocated to no more than three Separate Account
Divisions.

The Fixed Rate Option will not be maintained after the retirement date. Any
portion of the accumulation value in the Fixed Rate Option on the retirement
date will be applied to the annuity payout option elected.

The Company will credit interest on the portion of net premium(s) applied to and
any amounts transferred to the Fixed Rate Option. Interest will accrue daily at
a minimum guaranteed annual rate of 3.5%. At the discretion of the Company an
interest rate in excess of the minimum guaranteed rate may be credited. The
Company will provide notice of the applicable interest rates in the annual
report to the Owner and upon request.

Any portion of a net premium allocated to the Fixed Rate Option on the issue
date will earn interest at the then current rate as set by the Company. This
interest rate will be guaranteed until the next contract anniversary.

After the issue date, any portion of net premium(s) applied to and any amounts
transferred into the Fixed Rate Option will earn interest at the then current
rate set by the Company. This rate will be guaranteed for the remainder of the
contract year, until the next contract anniversary.

On the contract anniversary, any portion of the accumulation value attributed to
the Fixed Rate Option will earn interest at the then current rate set by the
Company. This rate will be guaranteed until the next contract anniversary.

If, on any contract anniversary the interest rate the Company sets for the Fixed
Rate Option is more than 3 percentage points lower than the rate set for the
immediately preceding contract year, the Owner may withdraw all or a portion of
the accumulation value held in the Fixed Rate Option for at least one contract
year without that amount being subject to a surrender charge. The Company must
receive proper written request for such withdrawal at its Customer Service
Office within 60 days of such contract anniversary.

During the period up to 30 days before the retirement date the Owner may
transfer all or a portion of the accumulation units credited under this contract
among the Separate Account Divisions and the Fixed Rate Option, subject to the
following conditions:

      o     Proper written request for transfer must be received by the Company
            at its Customer Service Office. Other transfer procedures permitted
            by the Company, if any, must be followed as set out in the
            prospectus for this contract.

      o     Accumulation units may not be credited to or transferred into more
            than four Separate Account Divisions or to three Separate Account
            Divisions and the Fixed Rate Option at any time.

      o     The transfer of accumulation units from the Fixed Rate Option to a
            Separate Account Division may only be made once each year on or
            within 30 days after a contract anniversary. Transfers out of the
            Fixed Rate Option will be made in the same order as such amounts
            were allocated to the Fixed Rate Option. The maximum amount that may
            be transferred from the Fixed Rate Option each contract year is the
            greater of:

      o     33 1/3% of the portion of the accumulation value attributable to the
            Fixed Rate Option as of the contract anniversary; or

      o     $2,500.
<PAGE>

The number of additional accumulation units credited under this contract in the
newly elected Fixed Rate Option will be equal to (a) divided by (b), where:

      o     (a) is the value of the amount transferred; and

      o     (b) is the value of an accumulation unit in the Fixed Rate Option as
            of the end of the valuation date on which the proper written request
            for transfer is received by the Company at its Customer Service
            Office.

The Company reserves the right to limit the frequency of transfers of
accumulation units under the contract to once every 30 days and to charge for
such transfers in the future. Transfers into or out of the Fixed Rate Option are
not permitted after the retirement date.

Any partial withdrawals will first be allocated among the Separate Account
Divisions in the same proportion as the accumulation value in each Separate
Account Division bears to the total accumulation value then credited to the
separate account on the date of the withdrawal. Partial withdrawals in excess of
the amount allocated among the Separate Account Divisions will be allocated to
the Fixed Rate Option.

The Company reserves the right to defer the payment of amounts withdrawn from
the Fixed Rate Option for a period not to exceed six months from the date proper
request for such withdrawal is received by the Company. Benefits and values
provided under this rider equal or exceed those required by any state statute
where the contract is delivered.

Attached on the issue date of the Contract.

                        AMENDMENT OF CONTRACT PROVISIONS

This rider is attached to and made part of the Contract. This rider is subject
to all of the applicable provisions of the Contract.

                             The Real Estate Option

This rider provides for a Real Estate Option (the RE Option). The RE Option is
supported by a separate investment account established by the Company under the
laws of the state of Delaware. This account is subject to the laws of the
jurisdiction in which this Contract is delivered.

Allocation of Premiums and Transfer of Accumulation or Annuity Units

The owner may allocate all or part of a premium to the RE Option.

The owner may transfer all or a portion of the accumulation units or annuity
units from one or more Separate Account Divisions or from the Fixed Rate Option
to the RE Option and from the RE Option to one or more Separate Account
Divisions, subject to the following conditions:

      o     if any part of the accumulation value is allocated to the RE Option,
            the remaining portion of the accumulation value may be allocated to
            no more than three Separate Account Divisions or two Separate
            Account Divisions and the Fixed Rate Option at any time.

      o     Proper written request for transfer must be sent to the Executive
            Office. Other transfer procedures permitted by the Company, if any,
            must be followed as set out in the prospectus for the Contract.

      o     Prior to the Retirement Date, the transfer of accumulation units
            from the RE Option to a Separate Account Division may only be made
            on or within 30 days after a Contract Anniversary. Transfer requests
            received within the 30 day period after a Contract Anniversary will
            take effect at the end of the business day on which the request is
            received.

      o     Any transfers of annuity units after the Retirement Date can be made
            only as of December 31st of any year.

      o     The maximum amount that may be transferred is the greater of:

            o     33 1/3% of the amount invested in the RE Option as of the
                  Contract Anniversary; or

            o     $10,000.

Accumulation Value

The Contract's accumulation value will vary daily with the performance of any
amount allocated to the RE Option. The accumulation value at any time will
reflect any transfers between the RE Option and any Separate Account Division or
Fixed Rate Option. On any day, any amount allocated to the RE Option will be
used to compute the Contract's accumulation value, accumulation units, and
annuity units in accordance with the methods set forth in the Contract.

Redemptions (Withdrawals)

Upon receipt of a proper request for partial or total redemption of the
Contract, the Company will cancel accumulation units with an aggregate value
equal to the dollar amount of the requested redemption plus, if applicable, any
Contract charges and withdrawal charges. The Company will cancel all
accumulation units attributable to the Contract's allocation to the Separate
Account Divisions before cancelling any units attributable to any allocation to
the RE Option. In addition, the Company will cancel all accumulation units
attributable to the Contract's allocation to the RE Option before cancelling any
units attributable to any allocation to the Fixed-Rate Option.

Voting Rights

Contract owners have no voting rights with respect to the RE Option.

Deferment

The Company reserves the right to defer payment of any Contract benefits (other
than guaranteed death benefits) funded by the RE Option (such as cash surrenders
and partial withdrawals under the Contracts) and transfers of Contract values
from the RE Option to the Separate Account Divisions for up to 6 months if there
appears to be insufficient cash available to meet such payment or transfer
requests and prompt disposition of the RE Option's investments to meet such
requests could not be made on commercially reasonable terms.

Issue Date

The issue date of this rider is the issue date of the Contractor the date of
attachment if later.

adopted setting forth a proposed amendment of the certificate of Incorporation
of the Corporation, declaring said amendment to be advisable and calling a
meeting of the stockholders of the Corporation for consideration thereof. The
resolution setting forth the proposed amendment is as follows:

     RESOLVED, that the certificate of Incorporation of the Corporation be
     amended by changing the Article thereof numbered "III" and Section thereof
     numbered "3.2" so that, as amended, said Article and Section shall be and
     read as follows:

     "Management and other Contracts. The Corporation may enter into a
     management, supervisory or investment advisory contract and other contracts
     with, and may otherwise do business with, any firm or organization
     notwithstanding that the directors or officers of the Corporation may be
     employees, directors or officers of such firms or organizations, and in the
     absence of fraud the Corporation and such firms or organizations may deal
     freely with each other, and such contracts or any other contract or
     transaction between the Corporation and such firms or organizations shall
     not be invalidated or in any wise affected thereby, nor shall any director
     or officer of the Corporation be liable to the Corporation or to any
     stockholder or creditor thereof or to any other person for any loss
     incurred by it or him under or by reason of any such contracts or
     transactions; provided that nothing herein shall protect any director or
     officer of the Corporation against any liability to the Corporation or to
     its security holders to which he would otherwise be subject by reason of
     willful misfeasance, bad faith, gross negligence or reckless disregard of
     the duties involved in the conduct of his office; and provided always that
     such contracts or transactions shall have been fair as to the Corporation
     as of
<PAGE>

     the time it was authorized, approved or ratified by the Board of Directors,
     a committee thereof, or the stockholders. No director of the Corporation
     shall be liable to the Corporation or its stockholders for monetary damages
     for breach of fiduciary duty as a director except for liability (i) for any
     breach of the director's duty of loyalty to the Corporation or its
     stockholders, (ii) for acts or omissions not in good faith or which involve
     intentional misconduct or a knowing violation of law, (iii) under Section
     174 of the Delaware General Corporation Law, or (iv) for any transaction
     from which the director derived an improper personal benefit."

     SECOND: that thereafter, pursuant to resolution of its Board of Directors,
a special meeting of the stockholders of the Corporation was duly called and
held, upon notice in accordance with Section 222 of the General Corporation Law
of the State of Delaware at which meeting the necessary number of shares as
required by statute were voted in favor of the amendment.

     THIRD: That said amendment was duly adopted in accordance with the
provisions of Section 242 of the General Corporation Law of the State of
Delaware.

     FOURTH: That the capital of the Corporation shall not be reduced under or

     Every person who was or is a party or is threatened to be made a party to
or is involved in any action, suit or proceeding, whether civil, criminal,

whom he is the legal representative is or was a director or officer of the
corporation or is or was serving at the request of the corporation or for its
benefit as a director or officer of another corporation, or as its
representative in a partnership, joint venture, trust or other enterprise, shall

and pursuant to any procedure specified in the General Corporation Law of the
State of Delaware from time to time against all expenses, liability and loss
(including attorneys' fees, judgments, fines and amounts paid or to be paid in
settlement) reasonably incurred or suffered by him in connection therewith. Such
right of indemnification 
<PAGE>

shall not be exclusive of any other right which such directors, officers or
representatives may have or hereafter acquire and, without limiting the
generality of such statement, they shall be entitled to their respective rights
of indemnification under any by-law, agreement, vote of stockholders, provision
of law or otherwise, as well as their rights under this Article.

                    AUTOMATIC INDEMNITY REINSURANCE AGREEMENT

                                     Between

                 THE GUARDIAN INSURANCE AND ANNUITY COMPANY, INC.

                                   of Delaware

                  hereinafter referred to as the "COMPANY" and

                 THE GUARDIAN LIFE INSURANCE COMPANY OF AMERICA

                                   of New York

                   hereinafter referred to as the "REINSURER"


                              giacagre.93a  page #1
<PAGE>

                              A. GENERAL PROVISIONS

1.   The COMPANY agrees to cede, and the REINSURER agrees to assume, the
     business defined in EXHIBIT A.

2.   This AGREEMENT is effective JANUARY 1, 1993, and shall remain in force as
     long as any of the annuity contracts specified above remain in force,
     unless recaptured by the Company. Either party may cancel for new business
     upon 30 days advanced written notice.

3.   On each contract ceded to the REINSURER, the liability of the REINSURER
     shall commence simultaneously with that of the COMPANY, and the COMPANY
     shall have the right to maintain the reinsurance in force as long as the
     COMPANY remains liable under any contract reinsured.

4.   The reinsurance hereunder shall be on the modified coinsurance (or calendar
     year renewable term) basis. The terms "Reserves" and "Mod Co Reserves" are
     defined in Exhibit F. The mod co reserves shall be maintained by the
     Company.

5.   The reinsurance shall be subject to the same terms and conditions as the
     contracts issued by the COMPANY.

6.   If the COMPANY'S liability under any of the contracts reinsured under this
     Agreement is changed because of a misstatement of age or sex, the REINSURER
     will share in the change proportionately to the amount reinsured hereunder.

7.   If a contract that had been reduced, terminated, or lapsed is reinstated by
     the COMPANY, the appropriate amount of reinsurance for such contract
     hereunder will be reinstated automatically. The COMPANY will pay the
     REINSURER the proportionate share of all amounts received by the COMPANY in
     connection with such reinstatement.

8.   The COMPANY must provide written notification to the REINSURER of any
     change in the terms or conditions of any contract reinsured hereunder or in
     the calculation of the Reserves within fifteen (15) days after the change
     is initiated. If the REINSURER accepts any such change, the COMPANY and the
     REINSURER shall share proportionately in any increase or decrease in the
     COMPANY's liability which results from such change. If the change is
     voluntary on the part of the COMPANY and if the REINSURER does not accept
     such change, or does not respond to the COMPANY, the REINSURER's liability
     under this Agreement shall be determined as if no such change occurred. If
     the change is not voluntary on the part of the COMPANY, the REINSURER shall
     participate in such change.

9.   It is expressly understood by the parties that the policies reinsured
     hereunder are nonparticipating. The expense allowances include provision
     for premium taxes, which


                              giacagre.93a  page #2
<PAGE>

     shall not be separately reimbursed by the REINSURER.

10.  Reinsurance transactions shall be accounted for in accordance with the
     procedure set forth in Exhibit G.

11.  Recapture shall be available under the terms set forth in Exhibit E.

12.  Should the COMPANY fail to cede reinsurance that should have been ceded in
     accordance with the provisions of this Agreement, or fail to comply with
     any of the other terms of this Agreement, and if this is shown to be
     unintentional and the result of a misunderstanding, oversight or clerical
     error on the part of either the COMPANY or the REINSURER, then this
     Agreement shall not be deemed abrogated thereby, but both companies shall
     be restored to the position they would have occupied had no such oversight,
     misunderstanding, or clerical error occurred.

13.  At any reasonable time, each party or its designated representative may
     inspect, during normal business hours, at the offices where such records
     are located, the papers and any and all other books or documents of the
     other relating to reinsurance under this Agreement. The information
     obtained shall be used only for reinsurance purposes and shall be kept
     confidential except to the extent disclosure is required by law. The
     REINSURER'S rights under this paragraph shall survive termination of this
     Agreement.

14.  This Agreement shall constitute the entire agreement between the parties
     with respect to the business reinsured hereunder. There are no
     understandings between the parties other than as expressed in this
     Agreement and any change or modification of this Agreement shall be null
     and void unless made by amendment to the Agreement and signed by both
     parties.

15.  This is an Agreement solely between the COMPANY and the REINSURER. The
     acceptance of reinsurance hereunder shall not create any right or legal
     relation whatever between the REINSURER and the insured or the beneficiary
     under any policies of the COMPANY which may be reinsured hereunder.

16.  The REINSURER does not indemnify and shall not be liable for any of the
     COMPANY'S extracontractual damages, including but not limited to actual
     punitive, exemplary or compensatory damages; excluded damages include but
     are not limited to damages or liability of any kind whatsoever resulting
     from, but not limited to: negligent, reckless or intentional wrongs, fraud,
     oppression, bad faith, or strict liability, arising from claims related to
     breach of contract or any form of tortious conduct. If the COMPANY is
     ordered by a court to make refunds to policyholders on any contract, the
     contract shall be considered a recaptured contract, and subject to the
     provisions of Exhibit E.

17.  Should the payment due either the REINSURER or the COMPANY be delayed
     beyond

                              giacagre.93a  page #3
<PAGE>

     30 days delayed payment shall accrue interest as specified in the
     computation of the Experience Account Asset.

                            B. PREMIUMS and BENEFITS

1.   Insuring Clause. The obligation of either party to the other is to pay the
     "Net Amount Due," which is the algebraic excess of the "Reinsurance
     Premium" over the "Reinsurance Benefits" as defined herein. The COMPANY
     shall pay the REINSURER the "Net Amount Due" if such is positive, and the
     REINSURER shall pay the ceding company the "Net Amount Due" if such is
     negative.

2.   The "Reinsurance Premium" is the net of (a)-(b)-(c)-(d)-(e):

(a)  Policy Premiums are the reinsured portions of the premiums paid by the
     policyholders, unreduced for any premium taxes.

(b)  Allowances are as defined in Exhibit C.

(c)  The Mod Co Reserve Adjustment for each accounting period equals V1 - VO - I
     where

     VO = Reserve at the beginning of the Accounting Period,

     V1 = Reserve at the end of the Accounting Period,

     I = Interest added to the reserve for all variable annuity contracts, plus
     all mortality and expense charges, during the Accounting Period. For any
     fixed annuities I shall be computed as the fixed annuity reserve at the
     beginning of the period times the rate as specified in EXHIBIT B.

     For the first accounting period, VO shall be zero. The "Reserves" shall
     equal the full account value, unreduced for any surrender charges.

(d)  Surrender Payments shall equal the reinsured portions of the surrender
     value paid to policyholders.

(e)  Experience Refunds are defined in Exhibit D.

3.   The "Reinsurance Benefits" shall equal the reinsured portion of the annuity
     income benefits (including commuted value benefits), and death benefits on
     the reinsured portions of the contracts, corresponding to the benefits paid
     by the Company.

     In the event that annuitization is made at rates more favorable to the
     annuitant than those guaranteed in the contract reinsured, such
     annuitization may be considered by the


                              giacagre.93a  page #4
<PAGE>

     REINSURER to be a surrender, in which case the REINSURER shall pay the full
     withdrawal value without reduction for any surrender charge.

4.   The "Accounting Period" shall be the calendar quarter, with the first
     accounting period running from the effective date to the end of the
     calendar quarter, and the last accounting period running from the beginning
     of a calendar quarter to the termination date.

5.   It is expressly understood that the "Reinsurance Premium" is an indivisible
     amount and not to be divided into component parts.

                                  C. INSOLVENCY

1.   In the event of the insolvency of the COMPANY, all reinsurance made, ceded,
     renewed or otherwise becoming effective under this Agreement shall be
     payable by the REINSURER directly to the COMPANY or to its liquidator,
     receiver, or statutory successor on the basis of the liability of the
     COMPANY under the contract or contracts reinsured without diminution
     because of the insolvency of the COMPANY. It is understood, however, that
     in the event of the insolvency of the COMPANY the liquidator or receiver or
     statutory successor of the insolvent COMPANY shall give written notice of
     the pendency of a claim against the insolvent COMPANY on the policy
     reinsured within a reasonable time after such claim is filed in the
     insolvency proceeding and that during the pendency of such claim the
     REINSURER may investigate such claim and interpose, at its own expense, in
     the proceeding where such claim is to be adjudicated any defense or
     defenses which it may deem available to the COMPANY or its liquidator or
     receiver or statutory successor.

     It is further understood that the expense thus incurred by the REINSURER
     shall be chargeable, subject to court approval, against the insolvent
     COMPANY as part of the expense of liquidation to the extent of a
     proportionate share of the benefit which may accrue to the COMPANY solely
     as a result of the defense undertaken by the REINSURER. Where two or more
     assuming insurers are involved in the same claim and a majority in interest
     elect to interpose defense to such claim, the expense shall be apportioned
     in accordance with the terms of the Reinsurance Agreement as though such
     expense had been incurred by the COMPANY.

2.   "Insolvent" means the insurer is subject to a rehabilitation or liquidation
     proceeding in any state in which it is licensed.

3.   If the COMPANY shall become insolvent and this contract is assigned by a
     rehabilitator or liquidator of the insolvent company, and if the assignee
     shall become insolvent, then this agreement may, at the REINSURER'S option
     be considered ipso facto terminated without any further payment due the
     COMPANY.

                        D. ARBITRATION and CHOICE of LAW

1.   In the event of any dispute relating to or arising under this Agreement,
     the dispute shall be referred to three arbitrators who must be current or
     former officers of insurance or reinsurance companies (either life/health
     or property and casualty) other than the two parties to this Agreement or
     their affiliates. Each of the contracting companies to appoint one of the
     arbitrators and such two arbitrators to select the third. Should the two
     arbitrators not be able to agree on the choice of the third, then the
     appointment shall be left to the American Arbitration Association.

     The arbitrators so chosen shall consider this Reinsurance Agreement not
     merely as a legal document but also as a gentlemen's agreement. The
     arbitrators shall consider the customary and standard practices of the
     reinsurance business. They shall not be bound by any rules of law. They
     shall decide by a majority of votes and from their written decision there
     shall be no appeal. The cost of arbitration, including the fees of the
     arbitrators, shall be borne equally by the REINSURER and the COMPANY. This
     article shall survive the termination of this Agreement.

2.   In all arbitrations and legal disputes (whether decided by arbitration or
     otherwise) the choice of law shall be New York.

3.   The arbitration or legal proceeding shall be held in New York.

                    E. OFFSET, RECOUPMENT, EXECUTORY CONTRACT

1.   All amounts due either party shall be netted, dollar for dollar, regardless
     of the solvency of either party.

2.   If one party gives notice to the other that it does not intend to pay the
     Net Amount Due as defined in this agreement, or if after 45 days written
     notice refuses to pay the Net Amount Due, then the other party is entitled
     to breach damages and may cancel for non payment, and if it chooses, not to
     pay any further amounts.

3.   Nothing in this agreement shall be construed to eliminate the defense of
     equitable recoupment.

4.   It is expressly understood that as long as payments are due both parties
     that this contract is an Executory Contract. Upon the insolvency of either
     party, the rehabilitator or liquidator of the insolvent party may affirm or
     disavow the contract within 90 days of the date the insolvency petition is
     filed with the appropriate court (hereinafter the "petition date"), unless
     the court having jurisdiction expressly extends such time limit. If
     affirmed it is expressly understood, by the parties, that the payments
     under this contract shall be entitled to the administrative expense
     priority, and if disavowed it is expressly understood


                              giacagre.93a  page #6
<PAGE>

     that the other party shall be entitled to breach damages and be freed from
     future performance. It is expressly understood that payments within a gap
     period, between the "petition date" and the date the contract is expressly
     affirmed or disavowed shall be entitled to an administrative expense
     priority.

                                F. TAX ELECTIONS

     The Company and the Reinsurer agree to make the election to ignore the
     General Deductions Limitation in Computing the net consideration between
     the parties.

     The Company agrees to reimburse the Reinsurer for the Internal Revenue
     Code, Section 848 Capitalized Policy Acquisition Expenses if the Section
     848 premium is positive (i.e. paid to the Reinsurer) and the Reinsurer
     agrees to reimburse the Company if the Section 848 premium is negative. The
     reimbursement will equal 10% of the capitalized amount. The 10% is based on
     34% corporate rate, 1.75% capitalization rate, 10 year amortization with a
     half-year convention and will be adjusted if such factors change.

     The Company and the Reinsurer hereby agree to the following pursuant to
     Section 1.848-2(g)(8) of the Income Tax Regulation issued December 1992,
     under Section 848 of the Internal Revenue Code of 1986, as amended. This
     election shall be effective for 1992 and for all subsequent taxable years
     for which this Agreement remains in effect.

     The term "party" will refer to either the Company or the Reinsurer as
     appropriate.

     The terms used in this Article are defined by reference to Regulation
     1.848-2 in effect December 1992.

     The party with the net positive consideration for this Agreement for each
     taxable year will capitalize specified policy acquisition expenses with
     respect to this Agreement without regard to the general deductions
     limitation of Section 848(c)(1).

     Both parties agree to exchange information pertaining to the amount of net
     consideration under this Agreement each year to ensure consistency or as
     otherwise required by the Internal Revenue Service.

     The Reinsurer will submit a schedule to the Company by June 1, of each year
     of its calculation of the net consideration for the preceding calendar
     year. This schedule of calculations will be accompanied by a statement
     stating that the Reinsurer will report such net consideration in its tax
     return for the preceding calendar year.

     The Company may contest such calculation by providing an alternative
     calculation to the Reinsurer by July 15th of the year following the end of
     the taxable year. If the Company does not notify the Reinsurer by July
     15th, the net considerations reported in the


                              giacagre.93a  page #7
<PAGE>

     respective tax returns will be the value as submitted to by the Reinsurer
     in the previous paragraph.

     If the Company contests the Reinsurer's calculation of the net
     consideration, the parties will act in good faith to reach an agreement on
     the correct amount within thirty (30) days of the date the Company submits
     its alternative calculation. If the Company and the Reinsurer reach
     agreement on an amount of the net consideration, each party shall report
     such amount in their respective tax returns for the previous calendar year.

                         EXHIBIT A - BUSINESS REINSURED

The business reinsured hereunder shall be a FIFTY PERCENT quota share of the
risk on the variable annuity contracts issued by the COMPANY comprising Guardian
Investor variable annuity contracts issued after January 1, 1993. The reinsured
business will include the reserves on the "fixed" option.

                 EXHIBIT B - MOD CO INTEREST and INTEREST RATES.

1.   The Interest added to the variable contract reserves is the aggregate
     interest, derived from all of the Net Investment Factors applicable to such
     class of contracts during such settlement period.

2.   The mortality and expense charge shall be equal to the mortality and
     expense charges issued by the company. For 1993 issues the charge will be
     estimated as 28.75 basis points per quarter times the "accumulation value"
     at the beginning of the quarter.

3.   On fixed account annuities the mod co interest shall equal the "Exhibit 2
     plus 4 rate" times the sum of the mod co reserve at the beginning of the
     quarter plus one half the algebraic excess of the reinsurance premium over
     reinsurance benefits during the quarter.

4.   The "Exhibit 2 + 4 rate" equals I/{.5 * (A + B - I)} 

     Where

     I = Net investment income plus realized capital gains less losses
     B = Current year invested assets
     A = Prior year invested assets

Note: 1992 Annual statement references.

     I is computed as follows:

          Gross Investment Income (Exhibit 2, line 10, column 7)
          Less Investment Expenses (Exhibit 2, line 15, column 7)
          Less Gain on Seed Investment Redeemed (Exhibit 4, line 9.201)
          Less Dividends on Common Stocks of Affiliates (Exhibit 2, line 2.21,
          column 7)
          Less Interest on Policy loans on life insurance policies (Exhibit 2,
          line 5, column 7, in part)
          Plus Net realized capital gains (Page 4, line 4a, column 1 plus Page
          4, line 32, column 1)


                              giacagre.93a  page #10
<PAGE>

     B =

          Cash and invested assets (Page 2, line 10a, column 1)
          Plus investment income due and accrued (Page 2, line 16, column 1)
          Less policy loans (Page 2, line 5, column 1)
          Less policy loans due and accrued on life products (Exhibit 2, line 5,
          columns 3 & 4, in part)
          Plus amount due from broker (Page 2, line 2103, column 1)
          Less borrowed money (Page 3, line 22, column 1)
          Less amounts due brokers (Page 3, line 2501, column 1)

     A is computed like B, but for the previous year.

The rate for the current calendar year will be based on the most recently filed
annual statement, and will be trued up (without interest) when the current year
statement is filed.

                 EXHIBIT C - ALLOWANCES and EXPERIENCE ACCOUNT

1.   The REINSURER shall pay the COMPANY the following allowances:

            Single premiums                           5.25%
            Initial flexible premiums                 5.25%
            Additional flexible premiums              5.25%

     In addition, the Reinsurer shall pay the COMPANY a renewal allowance of
     $5.00 per quarter per policy, and aggregating all policies issued to the
     same insured in the same year.

2.   The experience account asset (EA) at the inception of this treaty, before
     any amounts have been paid by either party shall be zero. Thereafter the EA
     at the end of any period shall be equal to the quantity (EA'), defined
     below, less any experience refund. The quantity (EM) equals:
     (a)+(b)-(c)-(d)+(e), where

          (a)  EA at the beginning of the period
          (b)  Cash Flow during the period, where the Cash flow is the algebraic
               excess of Reinsurance Premiums over Reinsurance Benefits
          (c)  DAC charge (positive if 848 premiums are paid to the REINSURER)
          (d)  Interest on the EA, at the Exhibit 2 plus 4 rate, (except that
               negative interest rates will be ignored for purposes of computing
               the EA).

     (Assuming the Reinsurance Premium less Reinsurance Benefits is negative,
     the EA will be negative, and the interest on the EA will be negative.)

     The DAC charge shall be equal to 10% of the capitalized amount as defined
     in Section


                              giacagre.93a  page #11
<PAGE>

     848 of the Internal Revenue Code. The 10% shall be based on 10-year
     amortization with the half year convention, with 1.75% capitalization rate,
     and with a 35% corporate income tax rate, and shall be changed is such
     factors change.

     The interest on the EA shall be the "Exhibit 2 plus 4 rate" as defined in
     Exhibit B

                         EXHIBIT D - EXPERIENCE REFUNDS

1.   The experience refund is calculated on an yearly basis, but estimates may
     be paid at the REINSURER'S discretion on a quarterly basis. The experience
     is one-half of the quantity (EA'), defined in Exhibit C, if (EA') is
     positive as of the end of each settlement period. The experience refund
     equals zero if (EA') is negative.

2.   On recapture a "terminal experience refund" will be paid, equal to 100% of
     the EA (before allowance for experience refund) if such is positive.

                              EXHIBIT E - RECAPTURE

1.   Two (2) years after the effective date The COMPANY may recapture the
     reinsurance ceded hereunder as of the end of any settlement period upon
     thirty days notice provided the "terminal experience refund" calculation
     produces a non-negative value of ER defined in Exhibit C subject to the
     conditions specified in this Exhibit D.

2.   In the final modified coinsurance reserve adjustment, the ending reserve
     "V1" is zero.

3.   The REINSURER shall pay the COMPANY the full withdrawal values without
     surrender charges on the contracts being recaptured. The amount thereof
     shall be included with contract benefits in the final experience refund
     calculation.

                             EXHIBIT F - DEFINITIONS

1.   The term "Mod Co Reserve" shall mean the policy accumulation value,
     unreduced by any surrender charge.

2.   The term "Reserve" shall mean the statutory reserves computed using the
     methodology the COMPANY used on its 12/31/92 annual statement for similar
     policies. It is expressly understood by the parties that "Reserves" are
     policy accumulation values, unreduced by any surrender charges.

                              AMENDED AND RESTATED
                AGREEMENT FOR SERVICES AND REIMBURSEMENT THEREFOR

     This Agreement, dated the 18th of November, 1994, amends and restates the
Agreement for Services and Reimbursement Therefor, dated June 22, 1970, between
THE GUARDIAN LIFE INSURANCE COMPANY OF AMERICA, a New York Corporation having
its principal place of business at 201 Park Avenue South, New York, New York
10003 (hereinafter called "GUARDIAN") and THE GUARDIAN INSURANCE & ANNUITY
COMPANY, INC., a Delaware Corporation having its principal place of business at
201 Park Avenue South, New York, New York 10003 (hereinafter called the
"SUBSIDIARY").

     WHEREAS, THE SUBSIDIARY is an insurance company wholly owned by GUARDIAN,
and

     WHEREAS, THE SUBSIDIARY was organized for the purpose among others of
distributing variable insurance and annuity products which are subject to the
regulation of the Securities and Exchange Commission and whose benefits are
dependent upon the performance of a portfolio of common stocks and other
investments, and

     WHEREAS, the net profit or net loss of THE SUBSIDIARY will ultimately
belong to GUARDIAN as the sole owner of the stock;

     NOW, THEREFORE, in consideration of the mutual advantages which will accrue
to each of the parties, it is hereby convenanted and agreed as follows;

     1. THE SUBSIDIARY will develop and qualify its various products for sale to
the public through those members of the Guardian Field Force and others as may
became eligible to do so.

     2. THE SUBSIDIARY will account for and administer its own activities as an
Insurance Company in accordance with the laws of the several states and the
federal laws and regulations of the Securities and Exchange Commission where
applicable.

     3. THE SUBSIDIARY undertakes to follow standards set by GUARDIAN in its
operations.

     4. As consideration for this Agreement and in connection with carrying out
the provisions hereof, GUARDIAN agrees to provide office space, furniture,
equipment, heat and light and clerical staff. It is further agreed that GUARDIAN
will pay salaries and provide pension benefits and other employee services
including health care
<PAGE>

benefits on the same basis for THE SUDSIDIARY'S officers and staff as for
regular full-time GUARDIAN employees. In the case of those individuals not fully
occupied in work for THE SUBSIDIARY, the proportion of salaries and other costs
attributable to the individual which should be charged to THE SUBSIDIARY will be
determined by time analysis methods. The total of such costs incurred and paid
by GUARDIAN on behalf of THE SUBSIDIARY will be repaid by THE SUBSIDIARY to
GUARDIAN at quarterly intervals upon demand accompanied by a detailed statement
substantiating the amount claimed. Such costs will be allocated by GUARDIAN to
THE SUBSIDIARY using GUARDIAN's cost accounting system. Costs will be allocated
to THE SUBSIDIARY based upon services provided by various Departments of
GUARDIAN as determined by either the Department's supervising officer or manager
or through an allocation developed by GUARDIAN's Cost Accounting Department
utilizing asset information, head count or overhead information.

                          [LETTERHEAD OF THE GUARDIAN]

April 29, 1992                                            Richard T. Potter, Jr.
                                                          Counsel

The Guardian Insurance & Annuity Company, Inc.
201 Park Avenue South
New York, New York 10003

Sir or Madam:

In my capacity as Counsel of The Guardian Insurance & Annuity Company, Inc.
("GIAC"), I am familiar with the legal affairs of GIAC and of The Guardian
Separate Account D (the "Account"), which is a separate account established by
the Board of Directors of GIAC on August 23, 1989, pursuant to the provisions of
Section 2932 of the Delaware Insurance Code. I have participated in the
preparation and review of the Registration Statement and Post-Effective
Amendment No. 3 to the Registration Statement (the "Registration Statement") on
Form N-4 filed by GIAC, on behalf of the Account, with the Securities and
Exchange Commission under the Securities Act of 1933 and the Investment Company
Act of 1940 for the registration of individual deferred variable annuity
contracts issued by GIAC (the "Contracts").

I have made such examination of law and examined such documents as in my
judgment are necessary and appropriate to enable me to express the following
opinion. I am of the opinion that:

     (1)  GIAC has been duly organized and is a validly existing corporation
          under the laws of the State of Delaware.

     (2)  The Account has been duly created and is validly existing as a
          separate account of GIAC under the laws of the State of Delaware.

     (3)  The portion of the assets that is held in the Account equal to the
          reserves and other liabilities for variable benefits under the
          Contracts is not chargeable with liabilities arising out of any other
          business GIAC may conduct.

     (4)  The Contracts, when offered, sold and issued in accordance with the
          Prospectus contained in the aforesaid Registration Statement and, upon
          compliance with applicable local law, will be legally issued and will
          represent binding obligations of GIAC in accordance with their terms.
