                                                                     May 1, 1998
    

                 INDIVIDUAL AND GROUP VARIABLE ANNUITY CONTRACTS

                                   Offered by

                 The Guardian Insurance & Annuity Company, Inc.

      The Individual Deferred Variable Annuity Contracts ("Individual
Contracts") and Group Deferred Variable Annuity Contract (the "Group Contract")
(collectively, the "Contracts") described in this Prospectus are offered and
issued by The Guardian Insurance & Annuity Company, Inc. ("GIAC") and are
designed to provide annuity benefits under retirement programs entitled to
Federal income tax benefits for individual purchasers and for group pension or
profit sharing plans and under deferred compensation plans and other retirement
plans which do not qualify for Federal tax benefits under the Internal Revenue
Code of 1986, as amended (the "Code").

   
      Net Premium Payments for the Contracts may be allocated in up to six of
the Contract's allocation options under which Contract values accumulate on
either a variable or fixed basis. These options consist of the ten mutual fund
investment divisions of The Guardian Separate Account A (the "Separate Account")
and the Fixed-Rate Option (available only to purchasers of a Single Premium
Payment Contract). Contractowner allocations to the divisions of the Separate
Account will be invested in the shares of the following underlying mutual funds:
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").
Contract values allocated to any of the Investment Divisions (referred to as the
"Variable Investment Options") will vary to reflect the investment performance
of such divisions. Net Premium Payments allocated to the Fixed-Rate Option will
accumulate on a fixed basis, with principal and minimum interest guaranteed by
GIAC.
    

      Two types of Individual Contracts are described in this Prospectus: (1) a
Single Premium Payment Contract (minimum purchase of $3,000) and (2) a Flexible
Premium Payment Contract (minimum initial purchase of $500). The Individual
Contracts may be issued under certain retirement plans which qualify for Federal
tax benefits under Sections 401, 403 or 408 of the Code. Following the date
pre-selected by the Contractowner for the payments to begin, these payments may
commence under one of the annuity options provided in the Contracts. The
Individual Contracts provide for a minimum pre-retirement death benefit.

                                                        (continued on next page)

                            SUMMARY OF THE CONTRACTS

      The Contracts described in this Prospectus are designed to provide annuity
benefits in accordance with the Annuity Payout Option selected and the
retirement plan, if any, under which a Contract has been issued. The Contracts
provide several underlying allocation options through which the Contractowner
may pursue his or her investment objectives. If the Contractowner selects the
Annuity Payout Option that provides for monthly payments during the lifetime of
the Annuitant, GIAC promises to make Annuity Payments continuously for the life
of the Annuitant under the Contract even if such Annuitant outlives the life
expectancy used in computing the Annuity. While GIAC is obligated to make such
Annuity Payments regardless of the longevity of the Annuitant, the amount of
variable annuity payments is not guaranteed. (See "Annuity Payout Options," page
24.) With respect to amounts attributable to the Variable Investment Options, no
assurance can be given that the value of the Contracts during the Accumulation
Period, or the aggregate amount of Annuity Payments made under the Contracts,
will equal or exceed the Net Premium Payments made to such Variable Investment
Options.

      GIAC provides for variable accumulations and benefits under the Contracts
by crediting Net Premium Payments to one or more of the Investment Divisions of
the Separate Account as selected by the Contractowner. The Investment Divisions
of the Separate Account correspond to the Funds offered under the Contracts. A
Contractowner may select up to six of the Variable Investment Options or, if
available to the Contractowner, the Fixed-Rate Option and five Variable
Investment Options. (See "Descriptions of the Variable Investment Options," page
15.) To the extent Net Premium Payments from a Single Premium Payment Contract
are credited to the Fixed-Rate Option, GIAC provides for fixed accumulations and
benefits. (See "Description of the Fixed-Rate Option," page 18.) The value of
the Contract prior to the Retirement Date and the amount accumulated to provide
Annuity Payments will depend upon the investment performance of the Variable
Investment Options selected by the Contractowner during the Accumulation Period,
except for amounts allocated to the Fixed-Rate Option. These latter amounts will
accrue interest at a rate not less than the minimum interest rate specified in
the Contract. (See "Accumulation Period," page 23 and "Annuity Period," page
23.) The investment risk under the Contract is borne by the Contractowner except
to the extent that Net Premium Payments are allocated to the Fixed-Rate Option
where the investment risk is borne by GIAC.

      Transfers among the Investment Divisions of the Separate Account are
permitted before and after the Retirement Date, subject to certain conditions
and in accordance with any applicable retirement plan. Certain restrictions
apply to transfers to or from the Fixed-Rate Option. (See "Transfers of Contract
Values," page 25.)

      The Contracts contain 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 ranging from 1.0% to
      5.0%. The percentage amount and the length of time for which this charge
      is applicable depends upon the particular Contract purchased. A federal
      income tax penalty may be imposed on surrenders or partial withdrawals.
      (See "Charges and Deductions," page 20, "Surrenders and Partial
      Withdrawals," page 26 and "Federal Tax Matters," page 28.

         (2) Withdrawals from Contracts issued in connection with Section 403(b)
      qualified plans are restricted under the Code. (See "Qualified Contracts
      -- Section 403(b) Plans," page 31, for information about the circumstances
      under which withdrawals may be made from such Contracts.)


                                       5
<PAGE>

         (3) Charges for the assumption by GIAC of the mortality and expense
      risks under the Contracts, the administrative expenses incurred by GIAC
      and state premium taxes, if any, are deducted from the Accumulation Value
      of the Contracts. (See "Charges and Deductions," page 20.) In addition,
      the Funds impose certain charges against their respective assets. (See the
      applicable Fund prospectus for information about these charges.)

   
         (4) In certain states, the Contractowner may cancel an individual
      Contract no later than ten (10) days (twenty (20) days in a limited number
      of states) after receiving it by returning the Contract along with a
      written notice of cancellation to GIAC. (See "Right to Cancel the
      Contract," page 35.) Certain Federal income tax advantages are currently

*     In any Contract year after the first and when such charge is applicable,
      10% of the amount of the single premium payment can be withdrawn without
      application of the charge. The maximum amount to which this charge may be
      applied cannot exceed the single premium payment.

**    In any Contract year after the first and when such charge is applicable,
      10% of the total premiums paid under the Contract in the last 72 months
      immediately preceding the date of withdrawal can be withdrawn without
      application of the charge. The maximum amount of this charge during the 72
      months immediately preceding the date of withdrawal will never exceed 5%
      of the total of premiums paid 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 annual 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.

      The following tables are designed to assist the Contractowner in
understanding the various costs and expenses of the Separate Account and its
underlying Funds. (See "Charges and Deductions," and see the accompanying Fund
prospectuses for a more complete description of the various costs and expenses.)
Premium taxes ranging from approximately 0.5% to 3.5% are currently imposed by
certain states and municipalities on payments made under the Contracts. GIAC
will deduct the applicable premium tax from premium payments made by
Contractowners in those states, counties and municipalities where such taxes are
imposed on GIAC. Where applicable, such taxes will decrease the amount of each
premium payment available for allocation.

      This expense comparison, and the expense comparison on the previous page,
assume that the expenses reported in the table on page 7 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.

                  DESCRIPTIONS OF GIAC AND THE SEPARATE ACCOUNT

GIAC

   
      The Guardian Insurance & Annuity Company, Inc. ("GIAC"), a stock life
insurance company incorporated in the state of Delaware in 1970, is the issuer
of the Contracts offered by this Prospectus. GIAC is licensed to conduct an
insurance business in all 50 states of the United 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, and the address of its 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 licensed to conduct an
insurance business in all 50 states and the District of Columbia. 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 Guardian Separate Account A (the "Separate Account")
in 1981 pursuant to the provisions of the Delaware Insurance Code. 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.

   
      There are ten Investment Divisions (which correspond to the ten Funds)
available for allocations of Net Premium Payments and Accumulation Values. Each
Investment Division invests in a specific underlying Fund and thereby reflects
that Fund's investment performance. Each such Division is divided into two
subdivisions, one for allocations under a tax qualified retirement plan and the
other for non-tax qualified plans, depending upon the plan under which the
Contract is issued. GIAC owns all of the Fund shares allocated to each
Investment Division but passes through to the Contractowners the voting rights
in such shares.
    

      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 Division's subdivision are credited to or charged against
the assets held in that subdivision in accordance with the terms of each
Contract, without regard to other income, capital gains or capital losses of the
other subdivisions. 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, if
permitted by an applicable retirement plan, the Participant. Selecting the
Fixed-Rate Option reduces the number of Funds which may be selected for
allocation. No sales charges are assessed against premium payments invested in
the Funds under the Contracts. Transfers among the Investment Divisions may
currently be effected without fee, penalty or other charge through proper
transfer requests to 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 shares at net asset value and retained as assets of the
Separate Account through allocation to the applicable Investment Division. Fund
shares will be redeemed by GIAC at their net asset value to the extent necessary
to make annuity or other payments under the Contract.

                 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 a 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;
or (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

                      DESCRIPTION OF THE FIXED-RATE OPTION

      That portion of the Single Premium Payment Contract relating to the
Fixed-Rate Option, described below, 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 Single Premium Payment Contracts are
offered.

      The purchaser of a Single Premium Payment Contract may allocate all or
part of the Net Premium Payment for his or her Contract 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% (the
"guaranteed minimum interest rate"). GIAC may also credit interest at a rate in
excess of 3% (the "excess interest rate") but is under no obligation to do so.
Any excess interest rate will be determined in 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 the portion of the accumulation value
in the Fixed-Rate Option may not exceed the guaranteed minimum interest rate
(3%) for any given year.

      There is no specific formula for the determination of whether to credit
excess interest or the rate thereof. 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 payment 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 the Net Premium Payment allocated
to the Fixed-Rate Option will be the rate in effect on the date the Contract is
issued. Any excess interest rate credited to the amount allocated to the
Fixed-Rate Option will be guaranteed until the next Contract Anniversary Date.
GIAC may change the excess interest rate credited to a particular Contract on
each subsequent Contract Anniversary Date and each such subsequent interest rate
will also be guaranteed for one Contract year until the following Contract
Anniversary Date.

      The Fixed-Rate Option will not be maintained after the Contractowner's
Retirement Date. Any accumulation value in the Fixed-Rate Option on the
Retirement Date will be applied to the Annuity Payout Option elected by the
Contractowner. Certain restrictions apply to transfers to and from the
Fixed-Rate Option (see "Transfers of Contract Values").

                          DESCRIPTIONS OF THE CONTRACTS

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

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

INDIVIDUAL CONTRACTS

      The Individual Contracts are only offered on the lives of individual
Annuitants. Two types of Individual Contracts are available: (1) a Single
Premium Payment Contract and (2) a Flexible Premium Payment Contract. Each of
these types of Individual Contracts are further subdivided into those which
qualify for special Federal income tax treatment ("Qualified Contracts") and
those which do not qualify for such treatment ("Non-Qualified Contracts"). (See
"Federal Tax Matters.")

      A minimum purchase payment of $3,000 is required under Single Premium
Payment Contracts. A minimum initial purchase payment of $500 is required under
Flexible Premium Payment Contracts. Thereafter, the minimum additional flexible
payment is $100. However, if a Flexible Premium Payment Contract is purchased
by, or in connection with, an employer payroll deduction plan, the minimum
amount GIAC will accept as a premium payment is $50 per Contract. The aggregate
of flexible premium payments made in any Contract year after the first may not
exceed ten (10) times the amount of the premium payments made in the first
Contract year or $100,000, whichever is less, without the written consent of
GIAC.

GROUP CONTRACT

      The Group 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 a plan or trust.

      The Contract is designed for use with several types of tax qualified plans
and other plans receiving favorable tax treatment, including retirement plans
established by corporate employers under Section 401 and public employee
deferred compensation plans under Section 457 of the Code. As such, the
provisions of the plan or trust should be referred to in connection with the
description of the Group Contract contained in this Prospectus.

      A minimum initial purchase payment of $5,000 is required, with additional
payments of at least $500 accepted. Subsequent payments in excess of $100,000 in
any one Contract year are acceptable only with the written consent of GIAC.

METHOD OF PURCHASE

      To purchase a Contract a complete application and initial premium payment
must be sent to The Guardian Insurance & Annuity Company, Inc., Customer Service
Office, P.O. Box 26210, Lehigh Valley, Pennsylvania 18002. Registered, certified
and express mail should be sent to such office at 3900 Burgess Place, Bethlehem,
Pennsylvania 18017. If the application is acceptable to GIAC in the form
received, the initial purchase payment will be credited within two (2) business
days after receipt. If the 


                                       19
<PAGE>

initial purchase payment cannot be credited within five (5) business days after
receipt by GIAC because the application is incomplete, GIAC will promptly return
the payment and application to the applicant. Acceptance is subject to GIAC's
rules and GIAC reserves the right to reject any application or initial purchase
payment.

      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 after the close of GIAC's business day will normally be
credited at the next accumulation unit value calculated on the first business
day following receipt.

CHARGES AND DEDUCTIONS

      Charges and deductions under the Contracts are made for GIAC's assumption
of mortality and expense risk and administrative expenses, for any applicable
premium taxes and, where applicable, charges (or credits) to the non-tax
qualified subdivisions of the Separate Account for Federal income taxes, if any.
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. The amount of this latter charge is based on the type
of Contract involved. The following describes each charge and deduction made
under the Contracts:

      Mortality and Expense Risk Deduction: The mortality risk assumed by GIAC
arises from its promise to pay death benefit proceeds and from its contractual
obligation to make Annuity Payments 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 life expectancy generally will have an adverse effect on the Annuity Payments
he or she will receive under a Contract 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 of .000027 of the value of the net assets of
each Variable Investment Option (1.0% on an annual basis consisting of
approximately .65% for mortality risks and approximately .35% for expense risks)
to compensate it for the assumption of these risks. In the event the
Contractowner has purchased the Enhanced Death Benefit Rider and for so long as
the Enhanced Death Benefit Rider remains in effect, GIAC will assess an
additional daily charge against the net assets of each Variable Investment
Option in an amount equal to .30% on an annual basis for expenses related to the
Enhanced Death Benefit. 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 use by it
to meet any operational expense, including that of 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 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 
    


                                       20
<PAGE>

   
fee paid to the adviser of the International Fund and the Emerging Markets Fund
is 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 its average daily net
assets. No separate fee is 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.
    

      Annual Contract Administration Fee: On each Contract Anniversary Date on
or before the Retirement Date, GIAC deducts a Contract administration fee of $30
from Individual Single Premium Payment Contracts and $35 from Individual
Flexible Premium Payment Contracts or Group Contracts by cancelling Accumulation
Units which are equal in value to the fee. This 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
deducts the Contract administration fee if a Contract is surrendered before the
Contract Anniversary Date. This fee is designed to reimburse GIAC for its actual
expenses incurred in administering the Contracts and it is not expected to
result in a profit. GIAC will not increase the Contract administration fee.

      Premium Taxes: Certain states and municipalities impose premium taxes when
premium payments are made or when annuity payments begin. Premium taxes range
from approximately 0.5% to 3.5% on premium payments made under the Contracts.
For those Contracts subject to a premium tax, GIAC deducts premium taxes either
from Contract premium payments when made or on the Retirement Date, as
determined in accordance with applicable law.

      Contingent Deferred Sales Charge: GIAC makes no separate sales charge
assessment in connection with the purchase of a Contract or subsequent premium
payments under a Flexible Premium Payment or Group Contract. 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 and the time periods for which it applies
differ depending upon the type of Contract purchased. In no event, however, will
the CDSC ever exceed, in the aggregate, 9% of the premium payments.

      In connection with Individual Single Premium Payment Contracts, the
following charges will be assessed upon amounts withdrawn during the first six
Contract years measured from the date of issue:

               Contract Year                             Charge
               ------------                              ------
                     1..................................   5%
                     2..................................   5%
                     3..................................   4%
                     4..................................   3%
                     5..................................   2%
                     6..................................   1%
                     7 and thereafter...................   0%

      However, in any Contract year after the first and when a CDSC is
applicable, 10% of the amount of the single premium payment can be withdrawn
annually by the Contractowner without application of the CDSC. Such withdrawals
may, however, be subject to penalty taxes and/or mandatory federal income tax
withholding. (See "Federal Tax Matters.") The maximum amount to which the CDSC
may be applied cannot exceed the single premium payment.

      In connection with Individual Flexible Premium Payment Contracts and Group
Contracts, the CDSC will be the lesser of (a) 5% of the total premiums paid
during the 72 months immediately preceding the date of withdrawal annually, or
(b) 5% of the amount being withdrawn. However, in any Contract year after the
first and when a CDSC is applicable, 10% of the total premiums paid under the
Contract in 


                                       21
<PAGE>

the last 72 months immediately preceding the date of withdrawal can be withdrawn
without application of the CDSC. Such withdrawals may, however, be subject to
penalty taxes and/or mandatory federal income tax withholding. (See "Federal Tax
Matters.") The maximum amount of the CDSC during the 72 months immediately
preceding the date of withdrawal will never exceed 5% of the total of premiums
paid during such period.

PRE-RETIREMENT DEATH BENEFIT

      Upon the death of the Annuitant (or the death of the Contractowner for
non-qualified Contracts) prior to the Retirement Date, an amount equal to the
Accumulation Value of the Contract (the current value of Accumulation Units
credited) as of the end of the Valuation Period during which GIAC receives due
proof of death, will be available for payment to the Beneficiary promptly after
proof of death is received by GIAC. (Under certain circumstances, the
Beneficiary may also choose to receive payments pursuant to one of the payout
options described under "Annuity Payout Options.") However, if death occurs
before the Annuitant reaches age 75 and before the Retirement Date, the death
benefit cannot be less than the total of all payments made under such Contract,
less a reduction for any prior redemptions and any charges assessed in
connection with those transactions. The Contractowner may designate a
Beneficiary and may change such designation at any time before Annuity Payments
begin.

   
OPTIONAL ENHANCED DEATH BENEFIT

      In addition to the pre-retirement death benefit provided under the
Contract, Contractowners may elect to purchase an optional Enhanced Death
Benefit Rider, which may provide greater death benefit proceeds than the
proceeds payable under the basic Contract. The Enhanced Death Benefit Rider is
available under current Contracts that have Annuitants who are under age 75 at
the time the Rider is issued. GIAC reserves the right to discontinue the offer
of the Enhanced Death Benefit Rider at any time without prior notice. Any Rider
purchased and issued prior to the date of such discontinuance will not be
affected by such event. Although not currently anticipated, GIAC may offer the
Rider from time to time in the future.

      If the Annuitant dies before the Retirement Date and the Rider is in
force, upon receipt of proof of death, GIAC will pay the Beneficiary a death
benefit equal to the greater of (1) the death benefit described in the basic
Contract or (2) the Enhanced Death Benefit. The Enhanced Death Benefit is equal
to the Accumulation Value of the Contract as of the end of the reset date
immediately preceding the Annuitant's date of death, plus any premiums paid
subsequent to such reset date, less any partial withdrawals subsequent to such
date, any applicable contingent deferred sales charges and any applicable
premium taxes.

      The first reset date occurs on the issue date of the Rider. Thereafter,
each reset date occurs on each subsequent seventh Rider anniversary. For so long
as the Enhanced Death Benefit Rider remains in effect, GIAC will assess an
additional daily charge against the net assets of each Variable Investment
Option equal to .30% on an annual basis for expenses related to the Enhanced
Death Benefit.

      The Enhanced Death Benefit Rider terminates on the earliest of (1) the
date the Enhanced Death Benefit is paid; (2) the date the Contract terminates;
(3) the date of the Annuitant's 85th birthday; (4) the Retirement Date; or (5)
the date GIAC receives the Contractowner's proper written request for
termination. Once the Enhanced Death Benefit is terminated, it may not be
reinstated.

      The Rider may not be available in all states.

ACCUMULATION PERIOD

      Allocation of Net Premium Payment: The initial Net Premium Payment is used
to purchase Accumulation Units in the Investment Divisions or the Fixed-Rate
Option (available to Single Premium Payment Contracts only), as selected by the
Contractowner, at the unit values next computed following GIAC's decision to
issue the Contract. Subsequent Net Premium Payments under Flexible or Group
Contracts will be allocated among the underlying Contract options as initially
selected for allocation or pursuant to new allocation instructions which have
been submitted in writing to GIAC at its Customer Service Office. New allocation
instructions will be implemented by GIAC following their receipt. 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 of the payment by GIAC. The number of Accumulation Units will not change
because of a subsequent change 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: The value of an Accumulation Unit is
determined by using one of two methods, depending upon whether it relates to a
Variable Investment Option or the Fixed-Rate Option. 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 performance 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

      Retirement Date: Annuity payments under the Contracts will begin on the
Retirement Date, which is the first day of the calendar month and year selected
by the Contractowner. This date cannot be later than the Annuitant's 85th
birthday, except where otherwise agreed to by GIAC. The Retirement Date 


                                       23
<PAGE>

may also be determined by the retirement plan under which the Contract is
issued.

      Annuity Payments: Annuity Payments will be determined on the basis of (a)
the table specified in the Contract which reflects the nearest age and sex of
the Annuitant(s), (b) the Annuity Payout Option selected, and (c) the
performance of the Variable Investment Options selected. The 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 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.

      The decision of the U.S. Supreme Court in Arizona Governing Committee v.
Norris can be interpreted to require all "employer-related plans" to use annuity
rate tables that are gender-neutral in calculating annuity purchase rates. In
order to accommodate employer-related plans funded by the Contracts,
gender-neutral annuity rate tables have been developed. Contracts that are not
purchased in connection with employer-related plans use gender-distinct annuity
rate tables except where prohibited by state law. Contracts offered by this
Prospectus to residents of such states will have Contract benefits which are
based on gender-neutral annuity rate tables.

      Annuity Payout Options: The Contractowner and, under certain
circumstances, the Beneficiary, may elect to have Annuity Payments made under
any one of the Annuity Payout Options specified in the Contracts and described
below. For Group Contracts, GIAC will issue a certificate to the Contractowner
for delivery to each Participant when an Annuity is provided for that
Participant. Each such certificate will set forth in substance the amount and
terms of the Annuity Payments and any other benefits the Participant may be
entitled to under the Contract. A change of Annuity Payout Option is only
permitted prior to the Retirement Date. In the absence of an election, Annuity
Payments will be made in accordance with the annuity form known as "Option 2 --
Life Annuity with 120 Monthly Payments Certain" (see below). Annuity Payments
will be made monthly except that (a) proceeds of less than $2,000 will be paid
in a single sum and (b) the schedule of monthly installment payments may be
changed to avoid payments of less than $20. The Annuity Payout Options currently
available under the Contracts are as follows:

               Option 1 -- Life Annuity Payments: An Annuity Payment made
         monthly during the lifetime of the Annuitant which terminates with the
         last monthly payment preceding the death of the Annuitant. Option 1
         offers the maximum level of monthly payments, since there is no
         guarantee of a minimum number of payments or provision for a death
         benefit for Beneficiaries. It would be possible under Option 1 for the
         Annuitant to receive only one Annuity Payment if he or she died before
         the due date of the second Annuity Payment, two such payments if he or
         she died before the third Annuity Payment date, and so on.

               Option 2 -- Life Annuity with 120 Monthly Payments Certain: An
         Annuity Payment made monthly during the lifetime of the Annuitant with
         the provision that if, at the death of the Annuitant, payments have
         been made for less than 120 months, Annuity Payments will be continued
         during the remainder of such period to the Beneficiary designated by
         the Contractowner. 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 certain Annuity Payments. If the Beneficiary
         dies while receiving Annuity Payments, the present value of the current
         dollar amount of the remaining number of certain Annuity Payments shall
         be paid in one sum to the estate of the Beneficiary.

               Option 3 -- Joint and Two-Thirds Survivor Annuity Payments: An
         annuity payment made monthly during the joint lifetimes of the
         Annuitant and a designated second person and continuing during the
         lifetime of the survivor in a reduced amount which reflects two-thirds
         of the number of 


                                       24
<PAGE>

         Annuity Units in effect when both persons were alive. It would be
         possible under Option 3 for the Annuitant and the designated second
         person to receive only one Annuity Payment if both died before the
         date of the second Annuity Payment, two such payments if both died
         before the third Annuity Payment date, and so on.

TRANSFERS OF CONTRACT VALUES

      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 both before and after the Retirement Date. No charge is
presently made by GIAC for implementing any transfer. Nevertheless,
Contractowners who contemplate requesting a transfer should carefully consider
their annuity objectives and the investment objectives of the Funds involved in
the proposed transfer before choosing to request a transfer. Frequent transfers
may be inconsistent with the long-term objectives of the Contracts.

      GIAC will implement transfers pursuant to proper written or telephone
instructions which specify in detail the requested changes. Proper transfer
requests received by GIAC at its Customer Service Office prior to 3:30 p.m.
Eastern time on a business day will normally be effected 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. Contractowners may be invested in a maximum of six
Variable Investment Options or the Fixed-Rate Option and five Variable
Investment Options under the Contract at any given time.

      Before telephone transfer instructions will be honored by GIAC, a
telephone authorization form, properly completed by the Contractowner, must be
on file at GIAC's Customer Service Office. If the proper authorization is on
file at GIAC's Customer Service Office, telephone transfer instructions may be
made by calling toll-free 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
request must include a precise identification of the Contract and the
Contractowner's Personal Security Code. GIAC may accept telephone transfer
instructions from any caller who properly identifies the Contract number and
Personal Security Code. The Funds, GISC and GIAC 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. Contractowners
risk possible loss of principal, interest and capital appreciation in the 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 instructions apply only to previously invested monies and do not
change the allocation instructions for any future Net Premium Payments under the
Contract. Allocations of future Net Premium Payments can only be changed by
proper written request.

      During periods of drastic economic or market changes, it may be difficult
to contact GIAC to request a telephone transfer. At such times, requests may be
made by regular or express mail and will be processed at the Accumulation Unit
Value on the date of 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.

      Up until 30 days before the Retirement Date, the Contractowner may
transfer all or part of the value of his or her Variable Investment Options to
another or other Variable Investment Options.

      After the Retirement Date, a Contractowner may also transfer all or a part
of the Annuity value from one or more Variable Investment Options to another or
other Variable Investment Options. However, such transfers may be made only once
per Contract 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. No transfers into or out of the Fixed-Rate Option are
currently permitted following the Retirement Date.


                                       25
<PAGE>

      Prior to the Retirement Date, each transfer between the Contract's
Variable Investment Options will be based upon the appropriate Accumulation Unit
values as of the valuation date coincident with or next following the date the
transfer instructions are received by GIAC at its Customer Service Office. Where
such transfer is requested after the Retirement Date, the number of old Annuity
Units will be changed to reflect the new number of Annuity Units based upon
their respective values on December 31st next following the receipt of
instructions by GIAC.

      A Contractowner may transfer amounts from the Fixed-Rate Option to any
Variable Investment Option once each Contract year and only during the 30-day
period beginning on the Contract Anniversary Date. If any Accumulation Value
remains in the Fixed-Rate Option, amounts may be transferred to no more than
three Variable Investment Options. The maximum amount which may currently be
transferred out of the Fixed-Rate Option each year is the greater of: (a) 25% of
the amount invested in the Fixed-Rate Option as of the applicable Contract
Anniversary Date or (b) $2,500. Transfer requests received within the 30-day
period beginning on the Contract Anniversary Date will normally be effected as
of the end of the business day on which the request is received. These limits
are subject to change in the future.

      A Contractowner may not currently transfer any portion of the Accumulation
Value from a Variable Investment Option to the Fixed-Rate Option. An owner may
only allocate part or all of a single Net Premium Payment directly into the
Fixed-Rate Option.

      GIAC may postpone requested transfers of all or part of the Contract
values under certain circumstances. See "Surrenders and Partial Withdrawals,"
below.

SURRENDERS AND PARTIAL WITHDRAWALS

      During the Accumulation Period, the Contractowner may redeem the Contract
in whole (known as a "surrender") or in part (know as a "partial withdrawal").
Surrenders and partial withdrawals must be requested in writing in a form
acceptable to GIAC. If the request is for surrender of the Contract, said
request must be accompanied by the Contract (or an acceptable affidavit of loss)
in order to be deemed a proper written request. GIAC will not process a request
for a surrender prior to the receipt of the Contract (or an acceptable affidavit
of loss) at its Customer Service Office. GIAC will not honor a request for
surrender or partial withdrawal after the Retirement Date.

      If a surrender or partial withdrawal is made in the first six (6) Contract
years, the contingent deferred sales charge may be imposed (see "Contingent
Deferred Sales Charge"). After the first Contract year, 10% of the amount of the
single premium payment with respect to Single Premium Payment Contracts and 10%
of the total premiums paid in the last 72 months immediately preceding the date
of withdrawal with respect to Flexible Premium Payment Contracts, can be
withdrawn without application of the contingent deferred sales charge.
Surrenders or partial withdrawals may also be subject to penalty taxes (see
"Federal Tax Matters").

      The Accumulation Value on a given day is equal to the sum of the value of
the Variable Accumulation Units and any Fixed Accumulation Units under the
Contract. 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 of the Valuation Period on or
next following the date proper written request for surrender or partial
withdrawal is received by GIAC at its Customer Service Office. If applicable,
the annual Contract administration fee and any contingent deferred sales charges
will be deducted from the surrender proceeds or the remaining Accumulation Value
by the cancellation of additional Accumulation Units.

      In connection with a surrender or partial withdrawal, Accumulation Units
will be cancelled in the following order: First, GIAC will cancel all the
Variable Accumulation Units attributable to the 


                                       26
<PAGE>

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 instructed
to the contrary by the Contractowner. Second, GIAC will cancel all Fixed
Accumulation Units attributable to the Fixed-Rate Option.

      Payment of a surrender or partial withdrawal will ordinarily be made
within seven days after the date a proper written request is received by GIAC 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: (a) the New York Stock Exchange is closed for trading or trading has been
suspended; or (b) the Securities and Exchange Commission ("SEC") restricts
trading or determines that a state of emergency exists which may make payment or
transfer impracticable. GIAC also 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 GIAC.

      The Contractowner may request a partial withdrawal of the Contract value
provided such partial withdrawal does not result in reducing the Contract value
to less than (a) $500 on the date of redemption for an Individual Single Premium
Payment Contract, (b) $250 on the date of the partial withdrawal for an
Individual Flexible Premium Payment Contract, or (c) $1,000 on the date of the
partial withdrawal for a Group Contract. If a partial withdrawal request would
result in any such reduction, GIAC will redeem the total Accumulation Value and
pay the remaining balance to the Contractowner. Such involuntary surrender would
be subject to the contingent deferred sales charge if surrender of the Contract
occurred within the time period for which this charge applied.
(See "Contingent Deferred Sales Charges.")

      NOTE: Withdrawals from Contracts issued in connection with Section 403(b)
qualified plans are restricted under the Internal Revenue Code. See "Qualified
Contracts -- Section 403(b) Plans," for information regarding the circumstances
under which withdrawals may be made from such Contracts.

OTHER IMPORTANT CONTRACT INFORMATION

      Assignment: Assignment of interests under the Contracts is prohibited when
the Contracts are used in connection with Keogh plans, any retirement plans
contemplated by Sections 403(b) or 408 of the Code and any corporate retirement
plan unless the Contractowner is not the Annuitant or the Annuitant's employer.
An assignment of the Contract may be treated as a taxable distribution to the
Contractowner. (See "Federal Tax Matters," below.)

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

      Contractowner Inquiries: A Contractowner may direct inquiries to the
individual who sold him or her the Contract or may call 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.

                               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 Account 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 Retirement 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 Contractowner dies prior to the Retirement Date, the entire interest
will be distributed within five years of the Contractowner's death.


                                       28
<PAGE>

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 taxes 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, amounts 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
Payment 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 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.


                                       29
<PAGE>

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


                                       30
<PAGE>

   
      For qualified plans under Section 401(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. Roth IRAs under Section
408A do not require distributions at any time prior to the Contractowner's
death.
    

      Following are brief descriptions of the various types of plans with which
the Contracts described in the 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)(1) 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
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 "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


                                       31
<PAGE>

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.

      Simplified Employee Pension (SEP) IRAs: Employers may establish Simplified
Employee Pension (SEP) IRAs under Code section 408(k) to provide IRA
contributions on behalf of their employees. In addition to all of the general
Code rules governing IRAs, such plans are subject to certain Code requirements
regarding participation and amounts of contributions.

      Roth IRAs: Section 408A of the Code permits certain eligible individuals
to contribute to a Roth IRA. Contributions to a Roth IRA, which are subject to
certain limitations, are not deductible and must be made in cash or as a
rollover or transfer from another Roth IRA or other IRA. A rollover from or
conversion of an IRA to a Roth IRA may be subject to tax and other special rules
may apply. You should consult a tax adviser before combining any converted
amounts with any other Roth IRA contributions, including any other conversion
amounts from other tax years. Distributions from a Roth IRA generally are not
taxed, except that, once aggregate distributions exceed contributions to the
Roth IRA, income tax and a 10% penalty tax may apply to distributions made (1)
before age 59 1/2 (subject to certain exceptions) or (2) during the five taxable
years starting with the year in which the first contribution is made to the Roth
IRA.

      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 transferrred 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 employers 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:


                                       32
<PAGE>

   
      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-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 follow these same principles, subject to a variety of
special rules. In particular, the 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 TAX 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 accumualted daily and transferred
from the Separate Account to the 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


                                       33
<PAGE>

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 the 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.

      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 typically 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 of 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.

      Prior to the Retirement Date, the person having the voting interest under
a Contract shall be the Contractowner. The number of shares held in the
Investment Division which are attributable to a Contract is determined by
dividing the Contractowner's interest in each subdivision by the net asset value
per share of the applicable Fund.

      After the Retirement Date, the person having the voting interest shall be
the person then entitled to receive Annuity Payments. This voting interest will
generally decrease with the gradual reduction of the Contract value during the
annuity payout period. The number of shares held in the Investment Divisions
which are attributable to each Contract is determined by dividing the reserve
for such Contract by the net asset value per share of the applicable Fund.

      Contractowners have no voting rights with respect to the Fixed-Rate
Option.

                          DISTRIBUTION OF THE CONTRACTS

   
      The contracts are 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 Contracts, 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 4.5% of a Contract
premium payment. Where permitted by state law, GIAC reserves the right to pay
additional sales or service compensation of up to .45% of the value of the
Contract annually while a Contract is in force based on the value of the
Contract and the riders selected by the Contractowner. The principal underwriter
of the Contracts is GISC, located at 201 Park Avenue South, New York, New York
10003.

<PAGE>

                          RIGHT TO CANCEL THE CONTRACT

      Where required by state law or regulation, the Individual 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 (20 days in a limited number of states) of delivery of the Contract. The
Contractowner will then receive from GIAC, as and when required by state law or
regulation, either (a) the total amount paid for the Contract or (b) 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.

                             ADDITIONAL INFORMATION

      A Statement of Additional Information is available (in accordance with the

                        SERVICES TO THE SEPARATE ACCOUNT

      The Guardian Insurance & Annuity Company, Inc. ("GIAC") maintains the
books and records of The Guardian Separate Account A (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 annual contract administration fee (as
described in the Prospectus), which are borne by the Contractowners.

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

   
      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 Contracts are
offered continuously and are sold by GIAC insurance agents who are registered
representatives of 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 the Contracts in the amount
of $1,979,926, $1,851,468 and $1,409,708, respectively.
    

                                ANNUITY PAYMENTS

      Determination of the First Monthly Annuity Payment: At the time Annuity
Payments begin, the value of the Contractowner's account (or if a Group
Contract, the amount applied for a participant as stated by the Contractowner)
is determined by multiplying the appropriate Accumulation Unit value on the
valuation date ten (10) days before the date the first Annuity Payment is due by
the corresponding number of Accumulation Units credited to the Contractowner's
account (or if a Group Contract, the amount applied for a participant as stated
by the Contractowner) as of the date the first Annuity Payment is due, less any
applicable premium taxes not previously deducted.

      The Contracts contain 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 amount depends on the form of Annuity, the sex (except
in those states which require "unisex" rates) and the nearest age of the
annuitant(s). The first Annuity Payment is determined by multiplying the benefit
per $1,000 of value shown in the Contract tables by the number of thousands of
dollars of value accumulated under the Contract (or if a Group Contract, the
amount applied for a Participant as stated by the Contractowner).

      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 4% investment return used in determining the amounts of
annuity payable. 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 after the first monthly
payment under an annuity option will be determined by multiplying the number of
Annuity Units 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 Second and Subsequent Monthly Annuity Payments: The
amount of the second and subsequent Annuity Payments is determined by
multiplying the number of Annuity Units by the appropriate Annuity Unit value as
of the valuation date 10 days prior to the day such payment is due. The number
of Annuity 


                                      B-2
<PAGE>

Units under a Contract is determined by dividing the first monthly payment by
the value of the appropriate Annuity Unit on the date of such payment. This
number of Annuity Units remains fixed during the Annuity Payment period,
provided no transfers among the Variable Investment Options are made.

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

      The second and subsequent monthly payments made under the Fixed-Rate
Option will be equal to the amount of the first monthly fixed annuity payment.

           CALCULATION OF YIELD QUOTATIONS FOR THE GUARDIAN CASH FUND

      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 Cash Fund and unrealized appreciation and depreciation with respect to
the portfolio securities of the Cash Fund, 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 (i) the net change in the value of the Contract
for the base period (see "Accumulation Period" in the Prospectus) by (ii) the
value of the Contract at the beginning of the base period and multiplying the
result by 365/7.

      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 (A) 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, (B) adding 1 to the result, (C) raising the sum to
a power equal to 365 divided by the number of days in the base period, and (D)
subtracting 1 from the result.

      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 does reflect 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 yield 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 portfolio of the Cash Fund. Consequently, no
yield quotation should be considered as representative of what the yield of the
subdivision may be for any specified period in the future. The Cash Fund
Investment Division's respective yields are not guaranteed.

   
      The current and effective annualized yields for the Investment Division
investing in the Cash Fund Investment Division for the seven-day period ending
December 31, 1997 were 5.24% and 5.38%, respectively, calculated as described
above.
    

                             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 independent performance data furnished by sources such as Lipper
Analytical Services, Inc., Morningstar, and Variable Annuity Research & Data
Service,


                                      B-3
<PAGE>

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 into consideration.

                   VALUATION OF ASSETS OF THE SEPARATE ACCOUNT

      The value of Fund shares held in each Separate Account 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 Annuity Units) may be
valued at fair value as determined in good faith by the Board of Directors of
GIAC.

                          TRANSFERABILITY RESTRICTIONS

      Where a Contract is owned in conjunction with a retirement plan qualified
under the Internal Revenue Code, a tax-sheltered annuity program or individual
retirement account, 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 Internal Revenue Code of 1986, the custodian of a custodial
account treated as such, or the employer under a qualified non-trusteed 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

                 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

                                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:

statements of income are $(2.3) million, $20.2 million and $7.2 million of
premiums at December 31, 1997, 1996 and 1995, respectively.

Note 7 -- Related Party Transactions

      Registered representatives of the Guardian Investor Services Corporation
produce a major portion of the Company's business. During 1997, 1996 and 1995,
premium and annuity considerations produced by GISC amounted to $564,519,265,
$528,353,595 and $400,148,692, respectively. The related commissions paid to
GISC amounted to $1,979,926, $1,851,468 and $1,409,708 for 1997, 1996 and 1995,
respectively.

      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.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed as of the day and year first written above.

Whereas, GIAC has appointed GISC as the Distributor of the Plans and has agreed
with GISC that GISC shall be responsible for the training and supervision of
such Representatives, with respect to the solicitation and offer or sale of any
of the Plans, and also for the training and supervision of any other "persons
associated" with Broker-Dealer who are engaged directly or indirectly therewith;
and GISC proposes to delegate, to the extent legally permitted, said supervisory
duties to Broker-Dealer; and

Whereas, GIAC and GISC propose to have Broker-Dealer provide certain
administrative services to facilitate solicitation for and sales of the Plans.

Now therefore, in consideration of the premises and the mutual covenants

Broker-Dealer shall be remitted promptly in full, together with such
applications, forms and any other required documentation, directly to GIAC at
the address indicated on such application or to such other address as GIAC may,
from time to time, designate in writing. Broker-Dealer shall review all such
applications for completeness. Checks or money orders in payment on any such
Plan shall be drawn to the order of "The Guardian Insurance & Annuity Company."
All applications are subject to acceptance or rejection by GIAC at its sole
discretion.

D. MONEY RECEIVED BY BROKER-DEALER

All money payable in connection with any of the Plans, whether as premium,
purchase payment or otherwise, and whether paid by or on behalf of any
policyholder, contract owner or certificate holder or anyone else having an
interest in the Plans, is the property of GIAC, and shall be transmitted
immediately in accordance with the administrative procedures of GIAC without any
deduction or offset for any reason, including by example, but not limitation,
any deduction or offset for compensation claimed by Broker-Dealer.
<PAGE>

E. SUPERVISION OF REPRESENTATIVES

Broker-Dealer shall have full responsibility for the training and supervision of
all Representatives associated with Broker-Dealer who are engaged directly or
indirectly in the offer or sale of the Plans, and all such persons shall be
subject to the control of Broker-Dealer with respect to such persons'
securities-regulated activities in connection with the Plans. Broker-Dealer will
cause the Representatives to be trained in the sale of the Plans: will use its
best efforts to cause such Representatives to qualify under applicable federal
and state laws to engage in the sale of the Plans; and will cause such
Representatives to be registered representatives of Broker-Dealer before such
Representatives engage in the solicitation of applications for the Plans; and
will cause such Representatives to limit solicitation of applications for the
Plans to jurisdictions where GIAC has authorized such solicitation.

to the satisfaction of GISC and shall notify GISC if any Representative ceases
to be a registered representative of Broker-Dealer.

F. REPRESENTATIVES AGREEMENT

Broker-Dealer shall cause each such Representative to execute a Registered
Representative's Agent Agreement with GIAC before a Representative shall be

execution by the Representatives.

G. COMPLIANCE WITH NASD RULES OF FAIR PRACTICE AND FEDERAL AND STATE SECURITY
   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

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
sales promotion materials or any advertising relating
<PAGE>

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,
but the same shall remain in full force and effect. No waiver of any of the
provisions of this Agreement shall be deemed, or shall constitute a waiver of
any other provisions, whether or not similar, nor shall any waiver constitute a
continuing waiver.

GIAC and GISC are independent contractors with respect to Broker-Dealer and to
Representatives.

C. LIMITATIONS

No party other than GIAC shall have the authority on behalf of GIAC to make,
after, or discharge any policy or contract or certificate issued by GIAC, to
waive any forfeiture or to grant, permit, nor to extend the time of making any
Payments, nor to guarantee dividends, nor to alter the forms which GIAC may
prescribe or substitute other forms in place of those prescribed by GIAC, nor to
<PAGE>

enter into any proceeding in a court of law or before a regulatory agency in
the
name of or on behalf of GIAC.

D. FIDELITY BOND

Broker-Dealer represents that all directors, officers, employees and
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,
Broker-Dealer shall promptly pay GIAC such amount on demand and Broker-Dealer
hereby indemnities and holds harmless GIAC from any such deficiency and from the
costs of collection thereof (including reasonable attorneys' fees).

<PAGE>

I. AMENDMENT OF AGREEMENT

GIAC reserves the right to amend this Agreement at any time and the submission

1.    General Definitions--As used in this Contract, the term:

      (a)   "Accumulation Value" means the value of all the Accumulation Units
            credited to this contract;

      (b)   "Accumulation Unit" means a unit of measurement used to determine
            the value of the Owner's interest under the contract before annuity
            payments begin;

      (c)   "Annuity Unit" means a unit used to determine the amount of each
            variable annuity payment after the first;

      (d)   "Contract Year" means the twelve month period starting with the date
            of contract issue or each succeeding twelve month period thereafter;

      (e)   "Fund(s)" means mutual fund(s) available under this contract for
            selection by the Owner to be the underlying Separate Account
            investment medium upon which the value of the contract and the
            amount of variable annuity payments thereunder are determined;

      (f)   "Premium" means an amount paid to the Company under this contract as
            a consideration for the benefits described herein;

      (g)   "Net Premium" means the gross amount of a Premium less any
            applicable premium taxes;

      (h)   "Retirement Date" is the date shown on page 3 or any other date
            chosen in accordance with Section 10;

      (i)   "Separate Account" means a segregated investment account entitled
            "The Guardian Separate Account A", established by the Company
            pursuant to applicable law and registered as a unit investment trust
            under the Investment Company Act of 1940, as amended;

      (j)   "Separate Account Division" means a Division of the Separate
            Account, the assets of which consist of shares of a specified Fund.
            Each of the Separate Account Divisions contains two subdivisions for
            measuring the funding results of contract accumulations and annuity
            payments. One subdivision is for contracts issued under tax
            qualified plans and the other for contracts issued under non-tax
            qualified plans. Each of the subdivisions will have its own
            identified values;

      (k)   "Valuation Date" means the date on which the accumulation unit value
            and annuity unit value of the Separate Account Divisions (and
            subdivisions) are determined (valuations are made daily);

      (l)   "Valuation Period" means the period between two Valuation Dates;

      (m)   "Variable Annuity" means a contract under which the Company promises
            to pay to the Annuitant or other properly designated payee one or
            more payments which vary in amount in accordance with the net
            investment experience of the applicable subdivision(s) of the
            Separate Account Division selected by the Contract Owner to measure
            the value of the contract.

2.    Separate Account and Funds--The net premium accepted by the Company
      hereunder will be allocated to the subdivision(s) of the Separate Account
      Division(s) which has been selected in writing by the Owner to measure the
      value of this contract. The applicable subdivision will be determined by
      the Federal tax status of the retirement plan under which the contract has
      been issued. The net premium will be used by the Company to purchase Fund
      shares applicable to the selected Separate Account Division at their net
      asset value. The Company shall be the owner of all Fund shares purchased
      with the net premium. No person having the right to receive any payments
      hereunder shall be entitled to receive the Fund shares allocated to any
      Separate Account Division. All Fund shares purchased by the Company and
      allocated to the Separate Account Divisions will be held for the exclusive
      benefit of persons entitled to receive benefits under variable annuity
      contracts, the owners of which have selected such Separate Account
      Division to measure the contract value. The income, if any, and gains or
      losses, realized or unrealized, on the amounts invested in the Fund shares
      are allocated to the specified Division for such Fund and will be credited
      to or charged against the amounts so allocated to such Division without
      regard to the other income, gains or losses on the assets allocated to any
      other Separate Account Division. No Separate Account Division shall be
      chargeable with the liabilities arising out of the business conducted by
      any other Separate Account Division; nor, shall the Separate Account as a
      whole be chargeable with the liabilities arising out of any other business
      that the Company may conduct. All dividends and capital gains
      distributions received from a Fund by the Company are reinvested in such
      Fund shares at their net asset value and allocated to the appropriate
      subdivision of the applicable Separate Account Division.

      Voting Rights and Reports--Fund shares held in a Separate Account Division
      which are attributable to either Accumulation Units or Annuity Units
      maintained under this contract shall be voted at meetings of the Fund
      pursuant to instructions received from the person having the voting
      interest in such shares. The number of Fund shares attributable to this
      Contract will be determined by the Company as of a date not more than 90
      days prior to the meeting of the Fund and voting instructions will be
      solicited by written communication at least ten days prior to such
      meeting.

      (a)   For Accumulation Units maintained under this contract, the number of
            Fund shares attributable thereto is determined by dividing the
            Accumulation Value by the net asset value of one Fund share. The
            person having the voting interest therein shall be the Owner.

      (b)   For Annuity Units maintained under this contract, the number of Fund
            shares attributable thereto is determined by dividing the reserve
            for such Annuity Units, as determined by the Company, by the net
            asset value of one Fund share. The person having the voting interest
            therein shall be the Owner.

            All Fund proxy material will be mailed to the last known address of
      each such person having a voting interest together with an appropriate
      form which may be used to give voting instructions with respect to the
      number of Fund shares he or she is entitled to vote.

            Fund shares held in a Separate Account Division under this contract
      as to which no timely voting instructions are received will be voted in
      proportion to the instructions received from all persons having an
      interest in such Separate Account Division pursuant to a Company issued
      variable annuity contract who do furnish timely instructions to the
      Company.

      Substituted Securities--If shares of a Fund(s) should not be available or
      if, in the judgment of the Company, further investment in such shares is
      no longer appropriate in view of the purposes of the Separate Account,
      there may be substituted therefor, subject to the approval of the
      Securities and Exchange Commission, shares of other registered open end
      investment companies, or 


                                       5
<PAGE>

      amounts credited to the Separate Account after a date specified by the
      Company may be applied to the purchase of shares of other registered open
      end investment companies in lieu of shares of the Fund(s).

3.    Payments To The Company--The Premium shown on page 3 is payable on or
      prior to the date of issue and only at the Company's Executive Office.

            Additional Premiums--In addition to the payment specified on page 3,
      the Company will accept at any time after the date of issue, but not later
      than the Retirement Date, additional premiums, provided each such premium
      is not less than $100. However, if the contracts are purchased by or in
      connection with an employer sponsored plan or through employee payroll
      deductions, the minimum amount the Company will accept as a purchase
      payment is $50. The aggregate of such additional premiums in any Contract
      year after the first may not exceed ten (10) times the amount of the
      aggregate payments made in the first contract year or $100,000, whichever
      is less, except with the specific consent of the Company.

            Net Premiums--The Company will apply Net Premiums in accordance with
      the designated percentage allocation specified in the Application or
      subsequent written notice filed with the Company to provide Accumulation
      Units of one or more subdivisions of Separate Account Division(s). The
      number of Accumulation Units for each subdivision of a Separate Account
      Division will be determined by multiplying a Net Premium by the percentage
      thereof to be allocated to the specified subdivision and then dividing the
      amount by the dollar value of one Accumulation Unit of the specified
      subdivision as of the Valuation Period during which the Premium is
      received at the Company's Executive Office. The dollar value of each
      Accumulation Unit may vary from one Valuation Period to the next Valuation
      Period and will depend on the investment experience of the selected
      subdivision of the Separate Account Division.

4.    Accumulation Unit Value--The value of the Accumulation Unit for each
      subdivision of a Separate Account Division was established at $10.00 as of
      the date on which the first Fund shares were purchased by the Company for
      that subdivision. For any particular Valuation Period thereafter, the
      Accumulation Unit Value is redetermined and is equal to the Accumulation
      Unit Value for the immediately preceding Valuation Period multiplied by
      the Net Investment Factor for the current Valuation Period.

5.    Net Investment Factor--The Company assesses a daily charge of .000027 of
      the value of the assets allocated to each subdivision of the Separate
      Account Divisions (.01 on an annual basis which is approximately .0065 for
      mortality risk and .0035 for expense risk) for its assumption of mortality
      and expense risks under the contract. (See Section 16 for an explanation
      of these guarantees.) The mechanism whereby this deduction is made is
      described as follows: for each subdivision of a Separate Account
      Division, the Net Investment Factor is determined by dividing the sum of:

      (a)   the net asset value of a Fund share determined as of the end of the
            current Valuation Period, and

      (b)   the per-share amount of any dividend and other distribution made by
            the Fund during the current Valuation Period.

      by the net asset value of a Fund share determined as of the end of the
      immediately preceding Valuation Period, and subtracting from this result
      (i) any applicable taxes, and (ii) a mortality and expense risk charge at
      the effective annual rate of 1%. Such charge is made in return for the
      Company's assumption of the risk that annuity payments may continue for a
      longer period than anticipated and that charges for sales and
      administration expenses may not be sufficient to cover the actual cost of
      these items. The net asset value of a Fund share is determined by the Fund
      or its agent and, as calculated, is reported to the Company. Since the Net
      Investment Factor is related to the investment experience of a Fund and
      this in turn is determined by changes in value of securities owned by a
      Fund, it may be less than 1.00 and, therefore, the value of an
      accumulation unit may decrease.

6.    Change of Separate Account Division--The Owner may elect to transfer all
      or any portion of the Accumulation Units credited under the contract (if
      the election takes place prior to the Retirement Date), or all or any
      portion of his or her Annuity Units credited under the Contract (should
      the election take place after the Retirement Date), from an existing
      subdivision of a Separate Account Division to one or more of the other
      Separate Account Divisions subdivision(s). A transfer after the Retirement
      Date can be made only as of December 31st of any year and no further
      transfer(s) can be made until the next following December 31st. If the
      transfer is made before the Retirement Date, the number of Accumulation
      Units credited under this Contract in the newly elected subdivision(s)
      will be equal to the dollar value of the amount transferred divided by the
      current value of one Accumulation Unit in the newly elected
      subdivision(s). If the transfer is made after the Retirement Date, the
      number of new Annuity Units credited in the newly elected subdivision is
      determined by first calculating the product obtained by multiplying the
      number of Annuity Units for each subdivision prior to the transfer by the
      value of one such Unit per subdivision, then dividing such product by the
      value of one Annuity Unit in the newly elected subdivision(s).

            The Company reserves the right to limit the transfer of Accumulation
      Units to once per month.

7.    Nonforfeiture Provision--Prior to the Retirement Date, the Owner may
      withdraw all or part of the Accumulation Value of this Contract. No
      partial withdrawal may be made which reduces the remaining Accumulation
      Value of the Contract to under $250. If such withdrawal reduces the
      Accumulation Value to under $250, the total balance of the Contract
      withdrawal value will be paid to the Owner and the Contract will be
      cancelled. The amount of any withdrawal payment will be reduced by any
      applicable premium taxes and surrender charges. All withdrawal payments
      will be made by the Company within seven days after the date that a
      written request in a form satisfactory to the Company is received by the
      Company at its Executive Office, except to the extent that the Company is
      permitted to defer the date of payment in accordance with applicable
      provisions of the Investment Company Act of 1940, as amended. The
      withdrawal value will be determined as of the Valuation Date coincident
      with or next following the date that the proper written request therefor
      is received by the Company.


                                       6
<PAGE>

8.    Surrender Charges--Certain amounts withdrawn from the Contract will be
      subject to a surrender charge. Such charge will be the lesser of (a) 5% of
      the total premiums paid during the 72 months immediately preceding the
      date of withdrawal, or (b) 5% of the amount being withdrawn. However, in
      any contract year after the first 10% of the total premiums paid under
      the Contract in the last 72 months immediately preceding the date of
      withdrawal can be withdrawn without application of the charge.

            The maximum amount of Surrender charges during the 72 months
      immediately preceding the date of withdrawal will never exceed 5% of the
      total premiums paid during such period.

9.    Administration Expense--On each anniversary of the Date of Issue of this
      Contract which is prior to the Retirement Date, the Company will deduct an
      administrative charge of $35.00 from the value of the Accumulation Units
      allocated to the contract. If the allocation is made to more than one
      subdivision of a Separate Account Division, the deduction will be made
      proportionately. The deduction is made upon surrender of the Contract
      prior to the anniversary date.

10.   Retirement Options

      Change of Retirement Date--Upon written request by the Owner received by
      the Company at least 60 days prior to the Retirement Date, the Retirement
      Date may be changed to any date which is not later than the Annuitant's
      85th birthday, unless a different time is agreed to by the Company in
      writing.

            Change of Retirement Annuity Form--During the Annuitant's lifetime,
      and prior to the time annuity payments begin, the Owner may change the
      form of the Retirement Annuity otherwise provided in the contract to one
      of the different Retirement Annuity Payout Option(s) described in Section
      12 by filing written notice of the change with the Company at least 60
      days before the Retirement Date. The amount which will be applied to
      provide the selected Retirement Annuity Payout Option will be the
      Accumulation Value less any applicable premium taxes and prior
      withdrawals. The payee under any selected Retirement Option shall be the
      Owner or any other payee designated by the Owner during the Annuitant's
      lifetime in writing and received by the Company. The Owner may, by written
      notice received by the Company during the Annuitant's lifetime, change a
      previously designated payee to another payee.

11.   Payments after the Annuitant's Death--In the event of the Annuitant's
      death on or before the Retirement Date, the Company, promptly after
      receipt in writing at its Executive Office of due proof of such death,
      will pay to the Beneficiary (or will apply under an Annuity Settlement
      Option as stated in Section 12 if the Beneficiary is a natural person) a
      death payment. If such death occurs prior to the Annuitant's attainment of
      age 65 and before the Retirement Date, the death payment will be equal to
      the Accumulation Value of the Contract (the value of all the Accumulation
      Units credited to this Contract excluding the value of any Accumulation
      Units previously withdrawn) or the premiums paid (reduced by any prior
      withdrawals) made to the Company under this Contract, whichever is
      greater. If such death occurs after the Annuitant's attainment of age 65
      and before the Retirement Date, the death payment will be equal to the
      Accumulation Value. In all cases the Accumulation Value is determined as
      of the Valuation Period by the end of which the Company shall have
      received due proof of death.

            If an election of an Annuity Payout Option with respect to the death
      payment is in effect at the time of the Annuitant's death, such death
      payment will be applied under such Option, after deducting an amount
      determined by the Company to be the appropriate charge for any applicable
      taxes on annuity considerations, to the extent not previously deducted by
      the Company in determining Net Premiums under this Contract.

12.   Annuity Payout Options (Retirement or Settlement)--The Annuity Payout
      Options are available under this Contract as Retirement Options or as
      Settlement Options. In addition to the following specified options of this
      Contract, the Owner (or the Beneficiary, if applicable) may also choose
      from any other options available from the Company at the time benefit
      payments are to begin. If an Annuity Payout Option is elected as a
      Retirement Option, then the "Annuitant" referred to in such Option is the
      person named as such on the Specifications Page of this Contract. If an
      Annuity Payout Option is elected as a Settlement Option, then the
      "Annuitant" referred to under the Annuity Payout Option is the Beneficiary
      or Beneficiaries in accordance with the provisions of Section 11. If
      Option 3 is chosen, the Owner, during the Annuitant's lifetime, (or the
      Beneficiary, if applicable) must also select a Joint Annuitant. The
      Annuity Payout Options are:

            Option 1--Life Annuity with No Refund--A monthly annuity payable
      throughout the lifetime of the Annuitant ceasing with the last installment
      prior to the death of the Annuitant.

            Option 2--Life Annuity with 120 Monthly Payments Certain--An annuity
      payable monthly during the lifetime of the Annuitant with the provision
      that if, at the death of the Annuitant, payments have been made for less
      than 120 months as elected, annuity payments will be continued during the
      remainder of such period to the Beneficiary designated by the Owner. 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 certain annuity payments. If the Beneficiary dies while receiving
      annuity payments, the commuted value of the current dollar amount of the
      remaining number of certain annuity payments, if any, shall be paid in one
      sum to the estate of the Beneficiary.

            Option 3--Joint and Two-Thirds Survivor Annuity--A monthly annuity
      payable throughout the joint lifetime of the Annuitant and the Joint
      Annuitant with two-thirds of the number of Annuity Units in effect during
      such joint lifetime continuing for life to the survivor upon the death of
      either Annuitant.

            The amount of the first installment for Options 1 through 3 above
      will be determined in accordance with Section 15 and the subsequent
      installments shall be determined in accordance with Section 16.

      General Provisions--The minimum amount of proceeds which may be applied
      under any Annuity Payout Option for any payee shall be $2,000; proceeds of
      a smaller amount due any Annuitant will be paid in one sum. If at any time
      the


                                       7
<PAGE>

      installment payments to any Annuitant under an Annuity Payout Option are
      or become less than $20 each, the Company shall have the right to change
      the frequency of payment to such intervals as will result in payments of
      at least $20.

            Annuity Payout Options are based on the sex and age nearest birthday
      of the Annuitant(s) as of the date such benefits are to start.
      Satisfactory proof of the age and sex of such Annuitant(s) is required.

            Except with the consent of the Company, these Annuity Payout Options
      shall 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
      in his or her own right.

            Neither the Owner nor any other person receiving payments under this
      contract, whether under an Annuity Payout Option or otherwise, shall have
      the right to assign, encumber or alienate any of the payments under an
      Annuity Payout Option. The Annuitant may make no change in the manner of
      payout except as provided in the election.

            To the extent permitted by law, neither the proceeds nor the
      payments under any Annuity Payout Option shall be subject to encumbrance
      and, to the extent permitted by law, shall not be subject to claims of
      creditors or legal process.

            At the time of the Annuitant's death after payments have commenced
      under an Annuity Payout Option, and if no Beneficiary has been previously
      designated, the then present value of the current dollar amount of any
      unpaid installments certain then due under Option 2 shall be paid in one
      sum to the executors or administrators of the estate of the Annuitant
      unless other provisions shall have been specified in the Annuity Payout
      election and approved by the Company. Present values will be based on a
      net investment rate of 4% per annum.

13.   Change of Beneficiary or Frequency of Payment of Proceeds--While this
      Contract is in force the Owner, subject to the terms of any existing
      assignment, may change the previously designated Beneficiary or
      Beneficiaries or may change the frequency of the annuity payments being
      made under the Contract to any different annuity payment frequency upon
      which the Owner and the Company may agree, by filing; at the Executive
      Office of the Company a written request therefor which is satisfactory to
      the Company. Such change, either in Beneficiary(ies) or in the frequency
      of annuity payments, shall take effect when so filed. If any designated
      Beneficiary predeceases the Annuitant, the interest of that Beneficiary
      shall pass to the designated surviving Beneficiary or, if more than one
      Beneficiary survives the Annuitant, such interest shall pass to such
      surviving Beneficiaries in proportion to their respective interests,
      unless otherwise previously specified by the Owner. If no designated
      Beneficiary survives the Annuitant and no other designation is provided,
      the proceeds of this Contract shall be payable in one sum to the Owner, if
      he or she survives the Annuitant; otherwise, to the executors or
      administrators of the Owner's estate.

14.   Annuity Unit Values--The value of an annuity unit is determined
      independently for each subdivision of a Separate Account Division. With
      respect to a particular subdivision, the value of an annuity unit was
      established at $1.00 as of the date Fund shares were first purchased for
      the Separate Account Division. For any valuation period thereafter the
      value of an annuity unit is recalculated and 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 amounts of annuity payable. The assumed investment
      return is 4% per year. The dollar amount of any monthly payment due after
      the first monthly payment under a variable annuity option will be
      determined by multiplying the number of annuity units by the value of an
      annuity unit for the valuation period ending ten days prior to the
      valuation period in which the monthly payment is due.

            The valuation of all assets in the Separate Account shall be
      determined in accordance with the provisions of applicable laws, rules and
      regulations. The method of determination by the Company of the value of an
      Annuity Unit and of an Accumulation Unit will be conclusive upon the
      Owner, any assignee, the Annuitant and any Beneficiary.

15.   Determination of the First Annuity Payment--At the time annuity payments
      begin, the value of the Owners account is determined by multiplying the
      accumulation unit value on the valuation date 10 days before the date the
      first annuity payment is due by the number of accumulation units credited
      to the Owner's account as of the date the first annuity payment is due,
      less applicable premium taxes not previously deducted.

            The Tables below indicate the dollar amount of the first monthly
      payment which can be purchased with each $1,000 of value accumulated under
      the Contract. The amount depends on the Annuity Payout Option, the sex and
      the nearest age of the Annuitant on the date the first annuity payment is
      due. Amounts shown in the Tables are based on the Sex Distinct 1971
      Individual Annuity Mortality Table, set back 5 years for males and 7 years
      for females, with interest at the rate of 4% per annum. The first annuity
      payment is determined by multiplying the applicable benefit per $1,000 of
      value shown in the Tables by the number of thousands of dollars of value
      accumulated under the Contract. The amount of the first monthly payment
      for ages or combination of ages not shown and for other options will be
      quoted upon request.

16.   Determination of the Amount of Annuity Payments After the First--The
      amount of the second and subsequent annuity payments is determined by
      multiplying the number of annuity units by the appropriate annuity unit
      value as of the valuation date 10 days prior to the day such payment is
      due. The number of annuity units under a Contract is determined by
      dividing the first monthly payment by the value of the appropriate annuity
      unit on the date of such payment This number of annuity units remains
      fixed during the annuity payment period, provided no Change of Separate
      Account Division is made. The Company guarantees that the dollar amount of
      each installment after the first shall not be adversely affected by the
      actual expenses which it incurs for administration of the contract or by
      variations in mortality experience from the mortality assumptions on which
      the first installment is based.

      Office and shall not be prejudiced by any payments made by it on the basis
      of a prior report or notice prior to the date which is seven days after
      receipt of the subsequent report or notice.

     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

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.

<PAGE>

                        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.

                                                     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 A (the "Account"), which is a separate account established by
the Board of Directors of GIAC on October 31, 1981, 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. 21 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 and group 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.
