VARIABLE FUND D
PROSPECTUS
INDIVIDUAL VARIABLE ANNUITY CONTRACT OF
MINNESOTA MUTUAL'S VARIABLE FUND D

The variable annuity contracts, which are more fully described in this
Prospectus, are designed to provide benefits under certain retirement programs
or plans which qualify for special federal income tax treatment.

The owner of a contract may elect to have contract values accumulated on a
completely variable basis, on a completely fixed basis (as part of Minnesota
Mutual's General Account and in which the safety of principal and interest are
guaranteed) or on a combination fixed and variable basis. To the extent that
contract values are accumulated on a variable basis, they will be a part of the
Variable Fund D. The Variable Fund D invests its assets in shares of Advantus
Series Fund, Inc. (the "Series Fund"). The variable accumulation value of the
contract and the amount of each variable annuity payment will vary in accordance
with the performance of the Portfolio or Portfolios of the Series Fund selected
by the contract owner or participant. The contract owner bears the entire
investment risk for any amounts allocated to the Portfolios of the Series Fund.

This Prospectus sets forth information that a prospective investor should know
before investing in the Variable Fund D, and it should be read and kept for
future reference. A Statement of Additional Information, bearing the same date,
which contains further contract and Variable Fund D information, has been filed
with the Securities and Exchange Commission and is incorporated by reference
into this Prospectus. A copy of the Statement of Additional Information may be
obtained without charge by calling (612) 665-3500, after September 1, 1998,
(651) 665-3500, or by writing the Variable Fund D at its principal office at
Minnesota Mutual Life Center, 400 Robert Street North, St. Paul, Minnesota
55101-2098. A Table of Contents for the Statement of Additional Information
appears in this Prospectus on page 31.

This Prospectus is not valid unless attached to a current
prospectus of Advantus Series Fund, Inc.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION, NOR HAS THE COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY
OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

THIS PROSPECTUS SHOULD BE READ CAREFULLY AND RETAINED FOR FUTURE REFERENCE.

THIS SYNOPSIS CONTAINS A BRIEF SUMMARY OF SOME OF THE IMPORTANT FEATURES OF THE
VARIABLE ANNUITY CONTRACTS DESCRIBED IN THIS PROSPECTUS. THE SUMMARY DOES NOT
PROVIDE A FULL DESCRIPTION OF THE CONTRACTS, WHICH IS PROVIDED ONLY IN THE
PROSPECTUS. YOU MAY FIND IT HELPFUL TO RE-READ THIS SUMMARY AFTER READING THE
PROSPECTUS, WHICH SHOULD BE RETAINED FOR FUTURE REFERENCE. A GLOSSARY OF SPECIAL
TERMS USED IN THIS PROSPECTUS MAY BE FOUND ON THE PRECEDING PAGE.

This Prospectus describes variable annuity contracts which are offered for use
in connection with certain retirement plans or programs entitled to special
federal income tax benefits. These plans or programs include: (a) employer
pension or profit-sharing plans qualified under Section 401(a) or 403(a) of the
Internal Revenue Code (the "Code"); (b) pension plans established by persons
entitled to the benefits of the Self-Employed Individuals Tax Retirement Act of
1962, as amended (H.R. 10 or Keogh plans); (c) annuity purchase plans adopted by
public school systems and certain tax exempt organizations pursuant to Section
403(b) of the Code; (d) individual retirement annuity plans adopted by
individuals pursuant to Section 408 of the Code; and (e) eligible state deferred
compensation plans described in Section 457 of the Code.

Several types of variable annuity contracts are offered by The Minnesota Mutual
Life Insurance Company ("Minnesota Mutual") in connection with Variable Fund D.
The contracts described in this Prospectus are a Flexible Payment Deferred
Variable Annuity and a Single Payment Deferred Variable Annuity, both of which
are subject to a deferred sales charge. The minimum purchase payment under the
Flexible Payment Deferred Variable Annuity contract is $25, a minimum which
Minnesota Mutual is currently waiving, while the minimum purchase payment amount
under the Single Payment Deferred Variable Annuity contract is $5,000. For a
detailed description of each type of contract, see "Description of the
Contracts" on page 19.

There is a right of revocation which exists for ten days after the contract is
received. See "Right of Revocation" on page 19.

The contracts are combined fixed and variable annuity contracts which provide
for monthly annuity payments. These payments may begin immediately or at some
future date. Purchase payments received under a contract are allocated either to
our General Account or to Variable Fund D. In the General Account, purchase
payments receive interest and principal guarantees; in the Variable Fund D, your
purchase payments are invested in one or more Portfolios of Advantus Series
Fund, Inc. and receive no interest or principal guarantees.

To the extent amounts are invested in the Portfolios of the Variable Fund D, the
value of the contract before the date annuity payments begin, and the amount of
monthly variable annuity benefits payable after that date, will increase or
decrease depending on increases or decreases in the market value of the
securities held by the Portfolios of the Series Fund.

This Prospectus describes only the variable aspects of the contracts, except
where fixed aspects are specifically mentioned. Please look to the language of
the contracts for a description of the fixed portion of the contracts. For more
information on the contracts, see the heading "Description of the Contracts" in
this Prospectus.

Currently, purchase payments allocated to the Variable Fund D are invested
exclusively in shares of Advantus Series Fund, Inc. The Series Fund is a mutual
fund of the series type, which means that it has several different portfolios
which it offers for investment. Shares of the Series Fund will be made available
at net asset value to the Variable Fund D to fund the variable annuity
contracts. The Series Fund is also required to redeem its shares at net asset
value at our request. We reserve the right to add, combine or remove other
eligible funds. The investment objectives and certain policies of the Portfolios
of the Series Fund which are available to the contracts offered by this
Prospectus are as follows:

The Growth Portfolio seeks the long-term accumulation of capital. Current
income, while a factor in portfolio selection, is a secondary objective. The
Growth Portfolio will invest primarily in common stocks and other equity
securities. Common stocks are more volatile than debt securities and involve
greater investment risk.

The Bond Portfolio seeks as high a level of long-term total rate of return
as is consistent with prudent investment risk. A secondary objective is to
seek preservation of capital. The Bond Portfolio will invest primarily in
long-term, fixed-income, high-quality debt instruments. The value of debt
securities will tend to rise and fall inversely with the rise and fall of
interest rates.

The Money Market Portfolio seeks maximum current income to the extent
consistent with liquidity and the stability of capital. The Money Market
Portfolio will invest in money market instruments and other debt securities
with maturities not exceeding one year. The return produced by these
securities will reflect fluctuation in short-term interest rates.

3
<PAGE>
AN INVESTMENT IN THE MONEY MARKET PORTFOLIO IS NEITHER INSURED NOR
GUARANTEED BY THE U.S. GOVERNMENT AND THERE CAN BE NO ASSURANCE THAT THE
PORTFOLIO WILL BE ABLE TO MAINTAIN A STABLE NET ASSET VALUE OF $1.00 PER
SHARE.

The Asset Allocation Portfolio seeks as high a level of long-term total rate
of return as is consistent with prudent investment risk. The Asset
Allocation Portfolio will invest in common stocks and other equity
securities, bonds and money market instruments. The Asset Allocation
Portfolio involves the risks inherent in stocks and debt securities of
varying maturities and the risk that the Portfolio may invest too much or
too little of its assets in each type of security at any particular time.

The Mortgage Securities Portfolio seeks a high level of current income
consistent with prudent investment risk. In pursuit of this objective the
Mortgage Securities Portfolio will follow a policy of investment primarily
in mortgage-related securities. Prices of mortgage-related securities will
tend to rise and fall inversely with the rise and fall of the general level
of interest rates.

The Index 500 Portfolio seeks investment results that correspond generally
to the price and yield performance of the common stocks included in the
Standard & Poor's Corporation 500 Composite Stock Price Index (the "Index").
It is designed to provide an economical and convenient means of maintaining
a broad position in the equity market as part of an overall investment
strategy. All common stocks, including those in the Index, involve greater
investment risk than debt securities. The fact that a stock has been
included in the Index affords no assurance against declines in the price or
yield performance of that stock.

The Small Company Portfolio seeks long-term accumulation of capital. In
pursuit of this objective, the Small Company Portfolio will follow a policy
of investing primarily in common preferred stocks issued by small companies,
defined in terms of either market capitalization or gross revenues.
Investments in small companies usually involve greater investment risks than
fixed income securities or corporate equity securities generally. Small
companies will typically have a market capitalization of less than $1.5
billion or annual gross revenues of less than $1.5 billion.

There is no assurance that any Portfolio will meet its objectives. Additional
information concerning the investment objectives and policies of the Portfolios
can be found in the current prospectus for the Series Fund, which is attached to
this Prospectus.

Subject to the limitations of the type of retirement program or a specific plan,
the contracts may be surrendered in whole or in part at any time prior to the
time that annuity payments begin for their accumulation value, less a deferred
sales charge, if any. See the discussion on withdrawals and surrender on page
26. A surrender or a withdrawal may result in adverse tax consequences. Once an
annuity option has been selected and payments begin, payments will be made only
in accordance with the terms of that option. These options, along with a
description of the method used to determine the amount of each variable annuity
payment, are found on page 21.

The allocation of future purchase payments may be made by giving Minnesota
Mutual written or telephone notice. And before annuity payments begin, a
contract owner or participant may transfer all or a part of existing
accumulation values between the General Account and the separate account or
among the sub-accounts of Variable Fund D. These transfers may be made by
written request to Minnesota Mutual and, generally, must be in amounts of at
least $250. Currently, Minnesota Mutual is waiving the enforcement of this
provision. For additional information on transfers please see the section on
page 24.

No deduction for a sales charge is made from the purchase payments for these
contracts. However, a deferred sales charge may be made on contract withdrawals
or surrenders during the first ten contract years. For flexible purchase payment
contracts the deferred sales charge is initially 9.0% of the amount withdrawn
with the percentage charge being reduced uniformly by .075% for each of the
first 120 months from the contract date. For single purchase payment contracts,
the deferred sales charge is initially 6.0% of the amount withdrawn with the
percentage charge being reduced by .05% for each of the first 120 months from
the contract date. Notwithstanding the existence of this charge, the contract
owner may withdraw or surrender up to 10% of the contract value at the prior
year-end without the application of such charge. In no event will the sum of any
deferred sales charges exceed 9.0% of the amount of purchase payments made under
the contract.

A deduction at the rate of .795% per year is made from the value of each
sub-account of Variable Fund D. This deduction is for the assumption by
Minnesota Mutual of mortality and expense risks. For additional information on
this deduction, see page 16.

In addition, Advantus Capital Management, Inc., a subsidiary of MIMLIC Asset
Management Company, which is a subsidiary of Minnesota Mutual, acts as the
investment adviser to the Series Fund and deducts from the net asset value of
each Portfolio of the Series Fund a fee for its services which are provided
under an investment advisory agreement. To the

4
<PAGE>
extent that the cost of investment advisory services in the Series Fund exceeds
.265%, Minnesota Mutual will make a reimbursement to Variable Fund D contracts.
For more information on this reimbursement, please see the section in this
Prospectus entitled "Contract Deductions."

Each Portfolio of the Series Fund is subject to certain expenses in addition to
its advisory fee. For funds allocated to the Growth Sub-Account, a portion of
these expenses may be reimbursed. For more information on this, see this
Prospectus under the heading "Contract Deductions." For more information on the
Series Fund, see the prospectus of Advantus Series Fund, Inc. which is attached
to this Prospectus.

Ascend Financial Services, Inc. ("Ascend Financial") acts as the principal
underwriter for the Variable Fund D. This firm is also affiliated with Minnesota
Mutual.

FINANCIAL STATEMENTS

The complete financial statements of Minnesota Mutual Variable Fund D and The
Minnesota Mutual Life Insurance Company are included in the Statement of
Additional Information.

GENERAL DESCRIPTIONS

A. THE MINNESOTA MUTUAL LIFE INSURANCE COMPANY

The Minnesota Mutual Life Insurance Company is a mutual life insurance company
organized in 1880 under the laws of Minnesota. Its home office is at 400 Robert
Street North, St. Paul, Minnesota 55101-2098 (612) 665-3500 after September 1,
1998, (651) 665-3500. It is licensed to do a life insurance business in all
states of the United States (except New York, where it is an authorized
reinsurer), the District of Columbia, Canada, Puerto Rico, and Guam.

B. MINNESOTA MUTUAL VARIABLE FUND D

On October 16, 1967, the Board of Trustees of Minnesota Mutual established a
separate account in accordance with certain provisions of Minnesota Insurance
Law. Minnesota Mutual Variable Fund D is the name by which this account is
designated. The Variable Fund D was registered as an open-end diversified
management investment company under the Investment Company Act of 1940, as
amended (the "1940 Act"). The separate account meets the definition of a
separate account under the federal securities laws.

The Minnesota law under which the Variable Fund D was established provides that
the assets of the Variable Fund D shall not be chargeable with liabilities
arising out of any other business which Minnesota Mutual may conduct, but shall
be held and applied exclusively for the benefit of the holders of those variable
annuity contracts for which the Variable Fund D was established. The investment
performance of the Variable Fund D is entirely independent of both the
investment performance of our general account and of any other separate account
which we may have established or may later establish. All obligations under the
contracts are general corporate obligations of Minnesota Mutual.

At a Special Meeting of contract owners and participants of Variable Fund D held
October 23, 1990, the contract owners and participants approved an Agreement and
Plan of Reorganization whereby Variable Fund D (which was a management
investment company investing primarily in a portfolio of equity securities,
mainly common stocks) transferred all of its assets to the Growth Portfolio of
the Advantus Series Fund, Inc. in exchange for shares of that Portfolio.
Variable Fund D was reconstituted and registered as a unit investment trust
under the 1940 Act. As part of that Reorganization it now consists of seven
sub-accounts, each investing its assets solely in the shares of one of seven of
the Series Fund Portfolios. The Series Fund has a number of Portfolios which are
not available to Variable Fund D. Registration with the Securities and Exchange
Commission (the "Commission") does not involve supervision of the management or
investment policies or practices of the Variable Fund D by the Commission.

C. ADVANTUS SERIES FUND, INC.

The Variable Fund D currently invests exclusively in Advantus Series Fund, Inc.
(the "Series Fund"), a mutual fund of the series type. Prior to May 1, 1997, the
name of the Series Fund was "MIMLIC Series Fund, Inc." The Series Fund is
registered with the Securities and Exchange Commission as a diversified,
open-end management investment company, but such registration does not signify
that the Commission supervises the management, or the investment practices or
policies, of the Series Fund. The Series Fund issues its shares, continually and
without sales charge, only to our separate accounts, which currently include the
Variable Annuity Account, the Variable Life Account, Variable Fund D, the Group
Variable Annuity Account, and the Group Universal Life Account. The Series Fund
may be made available to other separate accounts as new products are developed,
and may be used as the underlying investment medium for separate accounts of the
Northstar Life Insurance Company, a wholly-owned subsidiary of ours domiciled in
the State of New York. Shares are sold and redeemed at net asset value. In the
case of a newly issued contract, purchases of shares of the Portfolios of the
Series Fund in connection with the first purchase payment will be based on the
values next determined after issuance of the contract by us. Redemptions of
shares of the Portfolios of the Series Fund are made at the net asset value next
determined from the day we receive a request for transfer, partial withdrawal or
surrender at our home office. In the case of outstanding contracts, purchases of
shares of the Portfolio of the Series Fund for the Variable Fund D are made at
the net asset value of such shares next determined after receipt by us of
contract purchase payments.

The Series Fund's investment adviser is Advantus Capital Management, Inc.
("Advantus Capital"). Advantus Capital is a wholly-owned subsidiary of MIMLIC
Asset Management Company ("MIMLIC Management") which, prior to May 1, 1997,
served as investment adviser to the Series Fund. MIMLIC Management is a
wholly-owned subsidiary of Minnesota Mutual. Advantus Capital acts as an
investment adviser to the Series Fund pursuant to an advisory agreement. MIMLIC
Management is a subsidiary of Minnesota Mutual.

15
<PAGE>
A prospectus for the Series Fund is attached to this Prospectus. A person should
carefully read this Variable Fund D Prospectus and that for the Series Fund
before investing in the contracts.

It is conceivable that in the future it may be disadvantageous for variable life
insurance separate accounts and variable annuity separate accounts to invest in
the Series Fund simultaneously. Although Minnesota Mutual does not currently
foresee any such disadvantages either to variable life insurance policy owners
or to variable annuity contract owners, the Series Fund's Board of Directors
intends to monitor events in order to identify any material conflicts between
such policy owners and contract owners and to determine what action, if any,
should be taken in response thereto. Such action could include the sale of
Series Fund shares by one or more of the separate accounts, which could have
adverse consequences. Material conflicts could result from, for example, (1)
changes in state insurance law, (2) changes in Federal income tax laws, (3)
changes in the investment management of any of the Portfolios of the Series
Fund, or (4) differences in voting instructions between those given by policy
owners and those given by contract owners.

D. ADDITIONS, DELETIONS OR SUBSTITUTIONS

We retain the right, subject to any applicable law, to make substitutions with
respect to the investments of the sub-accounts of the Variable Fund D. If
investment in a fund should no longer be possible or if we determine it becomes
inappropriate for contracts of this class, we may substitute another fund for a
sub-account. Substitution may be with respect to existing accumulation values,
future purchase payments and future annuity payments.

We may also establish additional sub-accounts in the Variable Fund D and we
reserve the right to add, combine or remove any sub-accounts of the Variable
Fund D. Each additional sub-account will purchase shares in a new portfolio or
mutual fund. Such sub-accounts may be established when, in our sole discretion,
marketing, tax, investment or other conditions warrant such action. Similar
considerations will be used by us should there be a determination to eliminate
one or more of the sub-accounts of the Variable Fund D. The addition of any
investment option will be made available to existing contract owners on such
basis as may be determined by us.

We also reserve the right, when permitted by law, to de-register the Variable
Fund D under the Investment Company Act of 1940, to restrict or eliminate any
voting rights of the contract owners, and to combine the Variable Fund D with
one or more of our other separate accounts.

CONTRACT DEDUCTIONS

SALES CHARGES

No sales charge is deducted from the purchase payments for these contracts.
However, a deferred sales charge, when it is applicable, will be used for
expenses relating to the sale of the contracts.

The deferred sales charge is made on contract withdrawals or surrenders during
the first ten contract years, measured from the issue date of the contract. If
annuity payments commence during the first ten contract years, the deferred
sales charge may be assessed against the amount applied to provide the annuity.
The amount of any deferred sales charge applicable to a particular transaction
is deducted from the accumulation value.

Under the Flexible Payment Deferred Variable Annuity Contract the amount of the
deferred sales charge as a percentage of the amount surrendered, withdrawn, or
applied to provide an annuity at the end of each contract year is as shown in
Table 1. The percentages decrease uniformly by .075% for each of the first 120
months from the contract date. Any amounts withdrawn from the contract may also
be reduced by any applicable state premium taxes not previously deducted from
purchase payments. In no event will the sum of the deferred sales charges exceed
9% of the total purchase payments made under this contract.

Under the Single Payment Deferred Variable Annuity Contract the amount of the
deferred sales charge as a percentage of the amount surrendered, withdrawn, or
applied to provide an annuity at the end of each contract year is as shown in
Table 2. The percentages decrease uniformly by .05% for each of the first 120
months from the contract date. Any amounts withdrawn from the contract may also
be reduced by any applicable state premium taxes not previously deducted from
purchase payments. In no event will the sum of the deferred sales charges exceed
9% of the total purchase payments made under this contract.

</TABLE>

Under both contracts, if a withdrawal is made where the sum of all withdrawals
in that calendar year is equal to or less than 10% of the accumulation value at
the end of the previous calendar year, the deferred sales charge will not apply.
If the sum of the withdrawals exceeds that amount, the deferred sales charge
will apply only to the amount of the excess. Similarly, if the contract is
surrendered, the deferred sales charge will apply only to the extent that the
amount surrendered, when coupled with any withdrawals during the year, exceeds
10% of the accumulation value at the end of the previous calendar year.

Under current practices, Minnesota Mutual under this provision will allow
withdrawals during the first calendar year to be made without the imposition of
a deferred sales charge so long as withdrawals during the balance of the first
calendar year do not exceed 10% of the purchase payments applied to the contract
during that first calendar year.

Deduction of a deferred sales charge will be made on contracts in the contract
years shown except in the event of the death of the annuitant or on an election
of an annuity payment option which provides for benefits which are expected to
continue for a period of at least five years. In addition, Minnesota Mutual will
waive the deferred sales charge on that portion of a contract's accumulation
value which is applied to the purchase of an Adjustable Income Annuity, which is
an immediate variable annuity contract, issued by us. We will also waive the
sales charge on amounts withdrawn because of an excess contribution to a
tax-qualified contract.

17
<PAGE>

To the extent that sales charges are insufficient to recover sales expenses,
Minnesota Mutual will pay sales expenses from its other assets or surplus. These
assets may include proceeds from the mortality and expense risk charges
described below.

PREMIUM TAXES

Deductions for any applicable premium taxes may be made from each purchase
payment (currently such premium taxes range from 0.5% to 3.5%) depending upon
the applicable law.

INVESTMENT MANAGEMENT

Under contracts funded by Variable Fund D, all costs of operating Variable Fund
D as an investment management company originally were covered by an investment
management fee of .265% of contract or account values on an annual basis. As
Variable Fund D is now a unit investment trust rather than a managed investment
company, that investment management fee no longer will be paid. However,
contract values that are allocated to sub-accounts of Variable Fund D will be
invested in Series Fund Portfolios that do pay investment advisory fees (at a
rate of .40% on an annual basis for the Index 500 Portfolio, .75% for the Small
Company Portfolio and .50% for each of the five other available Portfolios) and
do incur other operating expenses. Those other operating expenses have been
voluntarily subsidized by Minnesota Mutual to the extent that the expenses
exceed .15% on an annual basis for any Portfolio. While Minnesota Mutual has no
present intention to alter that practice, it is under no obligation to continue
it.

To ensure that Contract Owners and Participants continue to get at least what
they originally expected under their contracts, Minnesota Mutual has agreed
that, each valuation period, in calculating the net investment factor for the
Growth Sub-Account of Variable Fund D, it will make adjustments that have the
effect of reimbursing the excess of any expenses indirectly incurred as a result
of the investment advisory fee paid and the operating expenses incurred by the
Growth Portfolio of the Series Fund over the former .265% investment management
fee. Accordingly, to the extent that the contract or account values continue to
be allocated to the sub-account that, in effect, continues the Variable Fund D
investment objective when it was operating as a management investment company,
there will be no change in the level of charges for the provision of investment
management services. In calculating the net investment factor for the other sub-
accounts of Variable Fund D, Minnesota Mutual will make adjustments that, in
effect, reimburse the excess of the investment advisory fees incurred through
indirect investment in the Series Fund Portfolios and the former .265%
investment management fee; however, any other Series Fund Portfolio operating
expenses would not be subject to the reimbursement. Accordingly, to the extent
that a Contract Owner or Participant chose to take advantage of the Variable
Fund D sub-accounts other than the Growth Sub-Account, he or she could incur
additional expenses.

MORTALITY AND EXPENSE RISKS

Minnesota Mutual assumes the mortality risk under the contract by its obligation
to continue to make monthly annuity payments, determined in accordance with the
annuity rate tables and other provisions contained in the contracts to each
annuitant regardless of how long he or she lives and regardless of how long all
annuitants as a group live. Thus, neither an annuitant's own longevity nor an
improvement in life expectancy generally will have an adverse effect on the
monthly annuity payments an annuitant will receive under the contract.

Minnesota Mutual assumes an expense risk by assuming the risk that deductions
provided for in the contracts for expenses may be insufficient to cover the
actual expenses incurred.

For assuming these risks, Minnesota Mutual currently makes a deduction from the
Variable Fund D at the rate of .1325% per annum for the mortality risk and
.6625% per annum for the expense risk. These deductions may be increased or
decreased by resolution of the Board of Trustees of Minnesota Mutual, but not
more often than annually, and in no event will the combined deductions exceed
the amount of the present deduction of .795% per annum. If the sum of such
deductions is insufficient to cover the risks assumed, the loss will fall on
Minnesota Mutual. Conversely, if the deductions provide more than sufficient,
any excess will be credited to the surplus of Minnesota Mutual.

EXPENSES

The Variable Fund D has no expenses which are not covered by the deductions
listed above. Minnesota Mutual performs all the administrative functions
relative to the contracts and it also bears all expenses associated with the
administration of the contracts. These include such items as salaries, rent,
postage, telephone, travel, office equipment and stationery, and legal,
actuarial and auditing fees.

OTHER EXPENSES

The underlying Portfolios also bear certain expenses. See the Advantus Series
Fund, Inc. prospectus for more information.

DESCRIPTION OF THE CONTRACTS

DESCRIPTION

The following material is intended to provide a general description of contract
terms. In the event that there are questions concerning the contracts which are
not discussed or should you desire additional information, then inquiries may be
addressed to us at: Minnesota Mutual Life Center, 400 Robert Street North, St.
Paul, Minnesota 55101-2098.

1. TYPES OF CONTRACTS

Minnesota Mutual continuously offers two types of variable annuity contracts
pursuant to this Prospectus:

(a) Single Payment Deferred Variable Annuity. This type of contract may be
used in connection with a qualified pension or profit sharing plan under which
plan contributions have been accumulating in a trust fund. It may also be used
in connection with a qualified plan which has previously been funded with
insurance contracts or fixed annuity contracts issued by Minnesota Mutual. The
contract provides for a fixed or variable annuity to begin at some future date
with the purchase payment made either in a lump sum or in a series of payments
in a single contract year. The contract may also be used to provide fixed
annuity or variable annuity payments under the state deferred compensation plans
or individual retirement annuity programs.

(b) Flexible Payment Deferred Variable Annuity. This type of contract may be
used in connection with all types of qualified plans, state deferred
compensation plans or with individual retirement annuities adopted by or on
behalf of individuals. The contract provides for a variable annuity or a fixed
annuity to begin at some future date with the purchase payments for the contract
to be paid prior to the annuity commencement date in a series of payments
flexible in respect to the date and amount of payment.

2. ISSUANCE OF CONTRACTS

The contracts are issued to the contract owner named in the application. The
owner may be the annuitant or someone else; however, once the owner has been
named in the application the ownership of the contract may not be changed.

3. RIGHT OF REVOCATION

The contract owner should read the contract carefully as soon as it is received.
The contract owner may revoke the purchase of a contract within ten days after
its delivery, for any reason, on notice to Minnesota Mutual at 400 Robert Street
North, St. Paul, Minnesota, of an intention to revoke. If the contract is
revoked and returned, Minnesota Mutual will refund to the purchaser the greater
of (a) the accumulation value of the contract or (b) the amount of purchase
payments paid under the contract. Payment of the requested refund will be made
to the purchaser within seven days after we receive notice of cancellation.

In some states, such as California, the free look period may be extended. In
California, the free look period is extended to thirty days' time for contracts
issued or delivered. These rights are subject to change, and may vary among the
states.

The liability of Variable Fund D under the foregoing is limited to the
accumulation value of any contract at the time it is returned for cancellation.
Any additional amounts necessary to make the refund to the owner equal to the
purchase payments will be made by Minnesota Mutual.

4. ANNUITY PAYMENTS

Variable annuity payments are determined on the basis of (a) the mortality table
specified in the contract, which reflects the age of the annuitant, (b) the type
of annuity payment option selected, and (c) the investment performance of the
Variable Fund D. The amount of the variable annuity payments will not be
affected by adverse mortality experience or by an increase in Minnesota Mutual's
expenses in excess of the expense deductions provided for in the contract. The
annuitant will receive the value of a fixed number of annuity units each month.
The value of such units and thus the amounts of the monthly annuity payments
will, however, reflect investment gains and losses and investment income of the
Variable Fund D, and thus the annuity payments will vary with the investment
experience of the assets of the Variable Fund D.

5. MODIFICATION OF THE CONTRACT

The contract may be modified at any time by written agreement between Minnesota
Mutual and the contract owner.

19
<PAGE>
6. ASSIGNMENT

The contract may not be assigned, sold, transferred, discounted or pledged as
collateral for a loan or as security for the performance of an obligation or for
any other purpose, and to the maximum extent permitted by law, benefits payable
under the contract shall be exempt from the claims of creditors.

7. LIMITATIONS ON PURCHASE PAYMENTS

The minimum purchase payment for the Single Payment Deferred Variable Annuity
Contract must be at least $5,000. It may not exceed $250,000 except with the
consent of Minnesota Mutual.

The minimum periodic purchase payment which may be made under a Flexible Payment
Deferred Variable Annuity Contract is $25. Currently, Minnesota Mutual is
waiving the enforcement of this provision.

There may be limits on the maximum contributions to retirement plans that
qualify for special tax treatment.

8. CONTRACT SETTLEMENT

Whenever any payment under a contract is to be made in a single sum, payment
will be made within seven days after the date such payment is called for by the
terms of the contract, except as payment may be subject for postponement for:

(a) any period during which the New York Stock Exchange is closed other than
customary weekend and holiday closings, or during which trading on the New York
Stock Exchange is restricted, as determined by the Securities and Exchange
Commission;

(b) any period during which an emergency exists as determined by the
Commission as a result of which it is not reasonably practical to dispose of
securities in the Variable Fund D or to fairly determine the value of the assets
of the Variable Fund D; or

9. PARTICIPATION IN DIVISIBLE SURPLUS

The contracts participate in the divisible surplus of Minnesota Mutual,
according to the annual determination of its Board of Trustees as to the
portion, if any, of the divisible surplus of Minnesota Mutual which has accrued
on the contracts.

No assurance can be given as to the amount of divisible surplus, if any, that
will be distributable under these contracts in the future. Such amount may arise
if mortality and expense experience is more favorable than assumed. No
distributions of divisible surplus have been declared on these contracts or
other contracts of Variable Fund D except as to certain group contracts sold
under circumstances which reduce sales expenses to Minnesota Mutual. When a
distribution of divisible surplus is made, it may take the form of additional
payments.

VOTING RIGHTS

The Series Fund shares held in the Variable Fund D will be voted by us at the
regular and special meetings of the Series Fund. Shares will be voted by us in
accordance with instructions received from contract owners with voting interests
in each sub-account of the Variable Fund D. In the event no instructions are
received from a contract owner, we will vote such shares of the Series Fund in
the same proportion as shares of the Series Fund for which instructions have
been received from contract owners with voting interests in each sub-account of
the Variable Fund D. In the event no instructions are received from a contract
owner, with respect to shares of a Portfolio held by a sub-account, Minnesota
Mutual will vote such shares of the Portfolio and shares not attributable to
contracts in the same proportion as shares of the Portfolio held by such
sub-account for which instructions have been received. The number of votes which
are available to a contract owner will be calculated separately for each
sub-account of the Variable Fund D. If, however, the Investment Company Act of
1940 or any regulation under that Act should change so that we may be allowed to
vote shares in our own right, then we may elect to do so.

During the accumulation period of each contract, the contract owner holds the
voting interest in each contract. The number of votes will be determined by
dividing the accumulation value of the contract attributable to each sub-account
by the net asset value per share of the underlying Series Fund shares held by
that sub-account.

During the annuity period of each contract, the annuitant holds the voting
interest in each contract. The number of votes will be determined by dividing
the reserve for each contract allocated to each sub-account by the net asset
value per share of the underlying Series Fund shares held by that sub-account.
After an annuity begins, the votes attributable to any particular contract will
decrease as the reserves decrease. In determining any voting interest,
fractional shares will be recognized.

20
<PAGE>
We shall notify each contract owner or annuitant of a Series Fund shareholders'
meeting if the shares held for the contract owner's contract may be voted at
such meeting. We will also send proxy materials and a form of instruction so
that you can instruct us with respect to voting.

ANNUITY PERIOD

1. ELECTING THE RETIREMENT DATE AND FORM OF ANNUITY

The contracts provide for four optional annuity forms, any one of which may be
elected if permitted by law. Each annuity option may be elected on either a
variable annuity or a fixed dollar annuity basis, or a combination thereof.
Other annuity options may be available on request to Minnesota Mutual.

While the contracts require that notice of election to begin variable annuity
payments must be received by Minnesota Mutual at least thirty days prior to the
annuity commencement date, Minnesota Mutual is currently waiving that
requirement for such annuity elections received at least two valuation days
prior to the fifteenth of the month. Minnesota Mutual reserves the right to
enforce the thirty day notice requirement at its option at anytime in the
future.

Annuity payments are always made as of the first day of a month. The contracts
require that notice of election to begin annuity payments must be received by us
at least thirty days prior to the annuity commencement date. However, Minnesota
Mutual currently waives this requirement, and at the same time reserves the
right to enforce the thirty day notice at its option in the future.

Money will be transferred to the General Account for the purpose of electing
fixed annuity payments, or to the appropriate variable sub-accounts for variable
annuity payments, on the valuation date coincident with the first valuation date
following the fourteenth day of the month preceding the date on which the
annuity is to begin.

If a request for a fixed annuity is received between the first valuation date
following the fourteenth day of the month and the second to last valuation date
of the month prior to commencement, the transfer will occur on the valuation
date coincident with or next following the date on which the request is
received. If a fixed annuity request is received after the third to the last
valuation day of the month prior to commencement, it will be treated as a
request received the following month, and the commencement date will be changed
to the first of the month following the requested commencement date. The account
value used to determine fixed annuity payments will be the value as of the last
valuation date of the month preceding the date the fixed annuity is to begin.

If a variable annuity request is received after the third valuation date
preceding the first valuation date following the fourteenth day of the month
prior to the commencement date, it will be treated as a request received the
following month, and the commencement date will be changed to the first of the
month following the requested commencement date. The account value used to
determine the initial variable annuity payment will be the value as of the first
valuation date following the fourteenth day of the month prior to the variable
annuity begin date.

If an election has not been made otherwise, and the plan does not specify to the
contrary, the annuitant's retirement date shall be the first day of the calendar
month next following his or her 65th birthday, the annuity option shall be
Option 2A, a life annuity with a period certain of 120 months. In this event, a
fixed annuity will be provided by any general account accumulation value and a
variable annuity will be provided by any Variable Fund D accumulation value. The
minimum first monthly annuity payment on either a variable or fixed dollar basis
is $20. If such first monthly payment would be less than $20, Minnesota Mutual
may fulfill its obligation by paying in a single sum the value of the contract
which would otherwise have been applied to provide annuity payments.

The contracts permit annuity payments to begin on the first day of any month
after the 50th birthday and before the 75th birthday of the annuitant.

Once annuity payments have commenced, the annuitant cannot surrender his or her
annuity benefit and receive a single sum settlement in lieu thereof.

The mortality and expense risks charge continues to be deducted throughout the
annuity period under each of the available annuity options, including Option 4,
under which there is no mortality risk to Minnesota Mutual.

Benefits under retirement plans that qualify for special tax treatment generally
must commence no later than the April 1 following the year in which the
participant reaches age 70 1/2 and are subject to other conditions and
restrictions.

2. OPTIONAL ANNUITY FORMS

OPTION 1--LIFE ANNUITY

This is an annuity payable monthly during the lifetime of the annuitant and
terminating with the last monthly payment preceding the death of the annuitant.
This option offers the maximum amount of monthly payments since there is no

21
<PAGE>
guarantee of a minimum number of payments or provision for a death benefit for
beneficiaries. It would be possible under this option for the annuitant to
receive only one annuity payment if he or she died prior to the due date of the
second annuity payment, two if he or she died before the due date of the third
annuity payment, etc.

OPTION 2--LIFE ANNUITY WITH A PERIOD CERTAIN OF 120 MONTHS (OPTION 2A), 180
MONTHS (OPTION 2B), OR 240 MONTHS (OPTION 2C)

This is an annuity payable monthly during the lifetime of the annuitant, with
the guarantee that if the annuitant dies before payments have been made for the
period certain elected, payments will continue to the beneficiary during the
remainder of the period certain; or if the beneficiary so elects at any time
during the remainder of the period certain, the present value of the remaining
guaranteed number of payments, based on the then current dollar amount of one
such payment shall be paid in a single sum to the beneficiary.

OPTION 3--JOINT AND LAST SURVIVOR ANNUITY

This is an annuity payable monthly during the joint lifetime of the annuitant
and a designated joint annuitant and continuing thereafter during the remaining
lifetime of the survivor. Under this option there is no guarantee of a minimum
number of payments or provision for a death benefit for beneficiaries.

OPTION 4--PERIOD CERTAIN ANNUITY

This is an annuity payable monthly for a Period Certain of from 3 to 15 years,
as elected. If the annuitant dies before payments have been made for the Period
Certain elected, payments will continue to the beneficiary during the remainder
of such Period Certain. At any time during the payment period, the payee may
elect that (1) the present value of the remaining guaranteed number of payments,
based on the then current dollar amount of one such payment and using the same
interest rate which served as a basis for the annuity, shall be paid in a single
sum, or (2) such commuted amount shall be applied to effect a life annuity under
Option 1 or Option 2.

3. VALUE OF THE ANNUITY UNIT

The value of an annuity unit is determined monthly as of the first day of each
month. The value of the annuity unit on the first day of each month is
determined by multiplying the value on the first day of the preceding month by
the product of (a) .997137, and (b) the ratio of the value of the accumulation
unit for the valuation date next following the fourteenth day of the preceding
month to the value of the accumulation unit for the valuation date next
following the fourteenth day of the second preceding month. (.997137 is a factor
to neutralize the assumed net investment rate, discussed in Section 4 below, of
3.5% per annum built into the annuity rate tables contained in the contract and
which is not applicable because the actual net investment rate is credited
instead.) The value of an annuity unit as of any date other than the first day
of a month is equal to its value as of the first day of the next succeeding
month.

4. DETERMINATION OF AMOUNT OF FIRST MONTHLY ANNUITY PAYMENT

Under the contracts described in this Prospectus, the first monthly annuity
payment is determined by the value of the contract at retirement. In addition, a
number of states do, however, impose a premium tax on the amount used to
purchase annuity benefits, depending on the type of plan involved. These taxes,
where applicable, currently range from 0.5% to 3.5% and are deducted from the
contract value applied to provide annuity payments, though Minnesota Mutual
reserves the right to make such deductions from purchase payments as they are
received.

When annuity payments commence, the value of the contract is determined as the
product of (a) the number of accumulation units credited to the contract, and
(b) the value of an accumulation unit.

The contracts contain tables indicating the dollar amount of the first monthly
payment under each optional annuity form for each $1,000 of value applied. The
amount of the first monthly payment depends on the optional annuity form elected
and the adjusted age of the annuitant. If, when annuity payments are elected, we
are using tables of annuity rates for these contracts which result in larger
annuity payments, we will use those tables instead.

A formula for determining the adjusted age is contained in the contract. The
tables are determined from the Progressive Annuity Table with interest at the
rate of 3.5% per annum, assuming births in the year 1900 and an age setback of
six years. The total first monthly annuity payment is determined by multiplying
the number of thousands of dollars of value applied (less any applicable premium
taxes not previously deducted) by the amount of the first monthly payment per
$1,000 of value from the tables in the contract. The 3.5% interest rate assumed
in the annuity tables would produce level annuity payments if the net investment
rate remained constant at 3.5% per year. Subsequent payments will be less than,
equal to, or greater than the first payment depending upon whether the actual
net investment rate is less than, equal to, or greater than 3.5%. A higher
interest rate would mean a higher initial payment, but a more slowly rising (or
more rapidly falling) series of subsequent payments. A lower assumption would
have the opposite effect.

22
<PAGE>
5. AMOUNT OF SECOND AND SUBSEQUENT MONTHLY ANNUITY PAYMENTS

The amount of the first monthly annuity payment, determined as described above,
is divided by the then current annuity unit value on the date of the first
payment to determine the number of annuity units represented by the first
payment. This number of annuity units remains constant during the period of
annuity payments, and in each subsequent month, the dollar amount of the annuity
payment is determined by multiplying this constant number of annuity units by
the then current value of an annuity unit.

The Statement of Additional Information contains an illustration of the
calculation of annuity unit values and of a variable annuity payment showing the
method used for the calculation of both the initial and subsequent payments.

DEATH BENEFIT

If the owner dies before annuity payments have started, we will pay the
accumulation value of the contract to the named beneficiary. The accumulation
value will be determined as of the valuation date coincident with or next
following the date that Minnesota Mutual receives due proof of death at its home
office. Death proceeds will be paid in a single sum to the beneficiary
designated by the contract owner, unless an annuity option is elected by the
beneficiary. Payment will be made within seven days after we receive due proof
of death and return of the contract. Except as noted below, the entire interest
in the contract must be distributed within five years of the owner's death. If
the annuitant dies after annuity payments have begun, Minnesota Mutual will pay
to the beneficiary any death benefit provided by the annuity option selected.
The person selected by the owner as the beneficiary of any remaining interest
after the death of the annuitant under the annuity option may be a person
different from that person designated as the contract beneficiary prior to the
annuity commencement date.

If the owner dies on or before the date on which annuity payments begin and if
the designated beneficiary is a person other than the owner's spouse, that
beneficiary may elect an annuity option measured by a period not longer than
that
beneficiary's life expectancy only so long as annuity payments begin not later
than one year after the owner's death. If there is no designated beneficiary,
then the entire interest in the contract must be distributed within five years
after the owner's death. If the annuitant dies after annuity payments have
begun, any payments received by a non-spouse beneficiary must be distributed at
least as rapidly as under the method elected by the annuitant as of the date of
death.

If any portion of the contract is payable to a designated beneficiary who is the
contract owner's surviving spouse, that spouse shall be treated as the contract
owner for purposes of: (1) when payments must begin, and (2) the time of
distribution in the event of the spouse's death. Payments must be made in
substantially equal installments.

If the owner of this contract is other than a natural person, such as a trust or
other entity, we will pay a death benefit of the accumulation value to the named
beneficiary on the death of the annuitant, if death occurs prior to the date for
annuity payments to begin.

The beneficiary will be the person or persons named in the contract application
unless the owner subsequently changes the beneficiary. In that event, we will
pay the amount payable at death to the beneficiary named in your last change of
beneficiary request. The owner's written request to change the beneficiary will
not be effective until it is recorded in Minnesota Mutual's home office records.
After it has been recorded, it will take effect as of the date the owner signed
the request. However, if the annuitant or the owner dies before the request has
been recorded, the request will not be effective as to those death proceeds we
have paid before the request was recorded in our home office records.

CREDITING ACCUMULATION UNITS

During the accumulation period--the period before the commencement of annuity
payments--the purchase payment (on receipt of a completed application or
subsequently) is credited on the valuation date coincident with or next
following the date such purchase payment is received. If the initial purchase
payment is accompanied by an incomplete application, the purchase payment will
not be credited until the valuation date coincident with or next following the
date a completed application is received. Minnesota Mutual will offer to return
the initial purchase payment accompanying an incomplete application if it
appears that the application cannot be completed within five business days.
Purchase payments will be credited to the contract in the form of accumulation
units. The number of accumulation units credited with respect to each purchase
payment is determined by dividing the portion of the purchase payment allocated
to each sub-account by the then current accumulation unit value for that
sub-account. The total of these separate account accumulation values in the
sub-accounts will be the separate account accumulation value. Interests in the
sub-accounts will be valued separately.

23
<PAGE>
The number of accumulation units so determined shall not be changed by any
subsequent change in the value of an accumulation unit, but the value of an
accumulation unit will vary from valuation date to valuation date to reflect the
investment experience of the Portfolios of the Series Fund.

Minnesota Mutual will determine the value of accumulation units on each day on
which the Portfolios of the Series Fund are valued. The net asset value of the
Series Fund's shares shall be computed once daily, and, in the case of Money
Market Portfolio, after the declaration of the daily dividend, as of the primary
closing time for business on the New York Stock Exchange (as of the date hereof
the primary close of trading is 3:00 p.m. (Central Time), but this time may be
changed) on each day, Monday through Friday, except (i) days on which changes in
the value of such Series Fund's portfolio securities will not materially affect
the current net asset value of such Series Fund's shares, (ii) days during which
no such Series Fund's shares are tendered for redemption and no order to
purchase or sell such Series Fund's shares is received by such Series Fund and
(iii) customary national business holidays on which the New York Stock Exchange
is closed for trading (as of the date hereof, New Year's Day, Martin Luther King
Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor
Day, Thanksgiving Day and Christmas Day).

Accordingly, the value of accumulation units will be determined daily, and such
determinations will be applicable to all purchase payments received by Minnesota
Mutual at its home office on that day prior to the close of business of the
Exchange. The value of accumulation units applicable to purchase payments
received subsequent to the close of business of the Exchange on that day will be
the value determined as of the close of business on the next day the Exchange is
open for trading.

In determining the value of the Series Fund on a valuation date, each security
traded on a national securities exchange is valued at the last reported sale
price on that date, as of the close of trading on the New York Stock Exchange.
If there has been no sale on such day, then the security is valued at the last
reported bid price on that day. Any security not traded on a securities
exchange, but traded in the over-the-counter market, is valued at the last
quoted bid price. Any securities or other assets for which market quotations are
not readily available are valued at fair market value as determined in good
faith by the Series Fund Board of Directors.

In addition to providing for the allocation of purchase payments to the
sub-accounts of the Variable Fund D, the contracts also provide for allocation
of purchase payments to Minnesota Mutual's General Account for accumulation at a
guaranteed interest rate. Purchase payments received without allocation
instructions will be allocated to the General Account.

TRANSFER OF VALUES

Upon your written request, values under the contract may be transferred between
the General Account and the Variable Fund D or among the sub-accounts of the
Variable Fund D. We will make the transfer on the basis of accumulation unit
values on the valuation date coincident with or next following the day we
receive the request at our home office. No deferred sales charge will be imposed
on such transfers. While the contracts currently provide that transfer amounts
must be of an amount not less than $250, we are waiving this restriction and
allowing transfers of any amount.

The contracts permit us to limit the frequency and amount of transfers from the
General Account to the Variable Fund D sub-accounts. Currently, except as
provided below, we limit the frequency of such transfers to a single such
transfer during any calendar year and the amount of such transfers to any amount
which is no more than 20% of the General Account accumulation value at the time
of the transfer. No transfers will be allowed after annuity payments have begun.

There are three situations which are exceptions to the above restriction. The
first is for new contracts where purchase payments are allocated to the General
Account because of the absence of initial allocation instructions. In that
situation, contract owners may make a single transfer of any amount from the
General Account. The second situation is where the contract owner has
established a systematic transfer arrangement with us. The contract owner may
transfer General Account current interest earnings or a specified amount from
the General Account on a monthly, quarterly, semi-annual or annual basis. For
transfers of a specified amount from the General Account the maximum initial
amount that may be transferred may not exceed 10% of the current General Account
accumulation value at the time of the first transfer. For contracts where the
General Account accumulation value is increased during the year because of
transfers into the General Account or additional purchase payments, made after
the program is established, systematic transfers are allowed to the extent of
the greater of the current transfer amount or 10% of the then current General
Account accumulation value. The third situation is in the case where the General
Account accumulation value is $1,000 or less. In that case, we will allow a
one-time transfer of the entire accumulation value from the General Account to
the Variable Fund D sub-accounts. Even with respect to systematic transfer
plans, we reserve the right to alter the terms of such programs once established
where funds are being transferred out of the General Account. Our alteration of
existing systematic transfer programs will be effective only upon our written
notice to contract owners of changes affecting their election.

24
<PAGE>
Transfer arrangements may be established to begin on the 10th or 20th of any
month and if a transfer cannot be completed it will be made on the next
available transfer date. In the absence of specific instructions, transfers will
be made on a monthly basis and will remain active until the appropriate General
Account accumulation value or sub-account is depleted.

Also, you or persons authorized by you may effect transfers, or a change in the
allocation of future premiums, by means of a telephone call. Transfers and
requests made pursuant to such a call are subject to the same conditions and
procedures as are outlined above for written transfer requests. During periods
of marked economic or market changes, contract owners may experience difficulty
in implementing a telephone transfer due to a heavy volume of telephone calls.
In such a circumstance, contract owners should consider submitting a written
transfer request while continuing to attempt a telephone redemption. We reserve
the right to restrict the frequency of--or otherwise modify, condition,
terminate or impose charges upon--telephone transfer privileges. For more
information on telephone transfers, contact Minnesota Mutual.

While for some contract owners we have used a form to pre-authorize telephone
transactions, we now make this service automatically available to all contract
owners. We will employ reasonable procedures to satisfy ourselves that
instructions received from contract owners are genuine and, to the extent that
we do not, we may be liable for any losses due to unauthorized or fraudulent
instructions. We require contract owners to identify themselves in those
telephone conversations through contract numbers, social security numbers and
such other information as we may deem to be reasonable. We record telephone
transfer instruction conversations and we provide the contract owners with a
written confirmation of the telephone transfer.

The interests of contract owners arising from the allocation of purchase
payments or the transfer of contract values to the general assets of Minnesota
Mutual are not registered under the Securities Act of 1933, and Minnesota Mutual
is not registered as an investment company under the Investment Company Act of
1940. Accordingly, such interests and Minnesota Mutual are not subject to the
provisions of those acts that would apply if registration under such acts were
required.

VALUE OF THE CONTRACT

The value of the contract at any time prior to the commencement of annuity
payments can be determined by multiplying the total number of accumulation units
credited to the contract by the current value of an accumulation unit. There is
no assurance that such value will equal or exceed the purchase payments made.
The contract owner and, where applicable, each participant will be advised
periodically of the number of accumulation units credited to the contract or to
the participant's individual account, the current value of an accumulation unit,
and the total value of the contract or the individual account.

ACCUMULATION UNIT VALUE

The value of an accumulation unit was set at $1.000000 on the first valuation
date of the Variable Fund D. The value of an accumulation unit on any subsequent
valuation date is determined by multiplying the value of an accumulation unit on
the immediately preceding valuation date by the net investment factor (described
below) for the valuation period just ended. The value of an accumulation unit as
of any date other than a valuation date is equal to its value on the next
succeeding valuation date.

NET INVESTMENT FACTOR

The separate account net investment factor describes the investment performance
of a sub-account of Variable Fund D. It is for the period from one valuation
period to the next. For any such sub-account, the net investment factor for a
valuation period is the gross investment rate for such sub-account for the
valuation period less a deduction for the mortality and expense risk charge at
the rate of .795%. The net investment factor for each sub-account other than the
sub-account holding shares of the Growth Portfolio of the Series Fund, shall be
increased by Minnesota Mutual. It will be increased to the extent that on an
annual basis the investment advisory fee accrued by the Portfolio in which the
sub-account invests, as a percentage of the value of the average net assets of
such Portfolio, exceeds .265% per annum. The net investment factor for the
sub-account holding shares of the Growth Portfolio of the Series Fund shall also
be adjusted by Minnesota Mutual. It will be adjusted so that on an annual basis
the expenses, including the investment advisory fee, of that Portfolio, as a
percentage of the average net assets of such Portfolio, exceed .265% per annum.
For purposes of this computation, "expenses" shall be determined on the basis of
generally accepted accounting principles applicable to registered investment
companies. However, they shall exclude any expenses of the Growth Portfolio
which are reimbursed by Minnesota Mutual or any other person, any interest
expense or amortization of debt discount or any income tax expense.

The gross investment rate is equal to: (1) the net asset value per share of a
fund share held in a sub-account of the separate account determined at the end
of the current valuation period; plus (2) the per share amount of any dividend
or

25
<PAGE>
capital gain distribution by such fund if the "ex-dividend" date occurs during
the current valuation period; divided by (3) net asset value per share of that
fund share determined at the end of the preceding valuation period. The gross
investment rate may be positive or negative.

WITHDRAWALS AND SURRENDER

Under both contracts, partial withdrawals may be made by the contract owner from
the contract for cash amounts of at least $250. In this event, the accumulation
value will be reduced by the amount of the withdrawal and the applicable
deferred sales charge. For more information on the application of that charge,
see "Sales Charges" on pages 16-17. In the absence of instruction to the
contrary, withdrawals will be first made from the general account accumulation
value and then from the separate account accumulation value. Any amounts
withdrawn from the contract may also be reduced by any applicable state premium
taxes not previously deducted from purchase payments. We will waive the
applicable dollar amount limitation on withdrawals where a systematic withdrawal
program is in place and such a smaller amount satisfies the minimum distribution
requirements of the Code. We will also waive the applicable dollar amount
limitation on withdrawals due to excess contributions, to a qualified contract.

The contracts provide that prior to the commencement of annuity payments, the
contract owner may elect to surrender the contract and receive in a single cash
sum the accumulation value computed as of the valuation date coincident with or
next following the date of surrender. The deferred sales charge will apply if
the surrender takes place in the first ten contract years. The sales charge will
be applied to the extent that amounts payable on surrender exceed 10% of the
accumulation value at the end of the previous calendar year, less any partial
withdrawals during the current calendar year.

Under any contract, once annuity payments have commenced for an annuitant under
Options 1, 2 or 3 of the optional annuity forms, the annuitant cannot surrender
his or her annuity benefit and receive a single sum settlement in lieu thereof.
For a discussion of commutation rights of payees and beneficiaries subsequent to
the annuity commencement date, see heading "Optional Annuity Forms."

Contract owners may also submit their signed written withdrawal or surrender
requests to us by facsimile (FAX) transmission. Our FAX number is (612)
665-7942, after September 1, 1998, (651) 665-7942, ATTN: U of M Plan Services.
Transfer instructions or changes as to future allocations of premium payments
may be communicated to us by the same means.

The surrender of a contract or a partial withdrawal thereunder may result in a
credit against Minnesota Mutual's premium tax liability. In such event,
Minnesota Mutual will pay in addition to the cash value paid in connection with
the surrender or withdrawal, the lesser of (1) the amount by which Minnesota
Mutual's premium tax liability is reduced, or (2) the amount previously deducted
from purchase payments for premium taxes. No representation can be made that
upon any such surrender or withdrawal any such payment will be made, since
applicable tax laws at the time of surrender or withdrawal would be
determinative.

DISTRIBUTION

The contracts will be sold by Minnesota Mutual life insurance agents who are
also registered representatives of Ascend Financial Services, Inc. or other
broker-dealers who have entered into selling agreements with Ascend Financial
Services, Inc. Ascend Financial Services, Inc. acts as the principal underwriter
of the contracts. Ascend Financial Services, Inc. is a wholly-owned subsidiary
of MIMLIC Asset Management Company, which in turn is a wholly-owned subsidiary
of Minnesota Mutual. MIMLIC Asset Management Company is also the sole owner of
the shares of Advantus Capital Management, Inc., the investment adviser for the
Series Fund. Ascend Financial Services, Inc. is registered as a broker-dealer
under the Securities Exchange Act of 1934 and is a member of the National
Association of Securities Dealers, Inc.

Commissions to dealers, paid in connection with the sale of the contracts, may
not exceed an amount which is equal to 6% of the purchase payments received for
the Flexible Payment Deferred Variable Annuity Contracts and 3.75% for the
Single Payment Deferred Variable Annuity Contracts.

In addition, Ascend Financial Services, Inc. or Minnesota Mutual will pay
credits which allow registered representatives (Agents) who are responsible for
sales of the contracts to attend conventions and other meetings sponsored by
Minnesota Mutual or its affiliates for the purpose of promoting the sale of
insurance and/or investment products offered by Minnesota Mutual and its
affiliates. Such credits may cover the registered representatives'
transportation, hotel accommodations, meals, registration fees and the like.
Minnesota Mutual may also pay registered representatives additional amounts
based upon their production and the persistency of life insurance and annuity
business placed with Minnesota Mutual.

FEDERAL TAX STATUS

INTRODUCTION

The discussion contained herein is general in nature and is not intended as tax
advice. Each person concerned should consult a competent tax adviser. No attempt
is made to consider any applicable state or other tax laws. In addition, this
discussion is based on our understanding of federal income tax laws as they are
currently interpreted. No representation is made regarding the likelihood of
continuation of current income tax laws or the current interpretations of the
Internal Revenue Service. The Contract may be purchased on a non-tax qualified
basis ("Non-Qualified Contract") or purchased and used in connection with
certain retirement arrangements entitled to special income tax treatment under
section 401(a), 403(b), 408 or 457 of the Code ("Qualified Contracts"). The
ultimate effect of federal income taxes on the amounts held under a Contract, on
Annuity Payments, and on the economic benefit to the Contract Owner, the
Annuitant, or the Beneficiary may depend on the tax status of the individual
concerned.

Minnesota Mutual is taxed as a "life insurance company" under the Internal
Revenue Code. The operations of the Variable Fund D form a part of, and are
taxed with, our other business activities. Currently, no federal income tax is
payable by us on income dividends received by the Variable Fund D or on capital
gains arising from the Variable Fund D's investment activities. However, if
changes in the federal tax laws or interpretations thereof result in Minnesota
Mutual being taxed on income or gains attributable to Variable Fund D, then we
may impose a charge against Variable Fund D (with respect to some or all
Contracts) in order to set aside provisions to pay such taxes.

TAXATION OF ANNUITY CONTRACTS IN GENERAL

Section 72 of the Internal Revenue Code governs taxation of nonqualified
annuities in general and some aspects of tax qualified programs. No taxes are
imposed on increases in the value of a contract until distribution occurs,
either in the form of a payment in a single sum or as annuity payments under the
annuity option elected. As a general rule, deferred annuity contracts held by a
corporation, trust or other similar entity, as opposed to a natural person, are
not treated as annuity contracts for federal tax purposes. The investment income
on such contracts is taxed as ordinary income that is received or accrued by the
owner of the contract during the taxable year.

For payments made in the event of a full surrender of an annuity, the taxable
portion is generally the amount in excess of the cost basis (i.e., purchase
payments) of the contract. Amounts withdrawn from the variable annuity contracts
not part of a qualified program are treated first as taxable income to the
extent of the excess of the contract value over the purchase payments made under
the contract. Such taxable portion is taxed at ordinary income tax rates.

In the case of a withdrawal under an annuity that is part of a qualified
program, a portion of the amount received is taxable based on the ratio of the
"investment in the contract" to the individual's balance in the retirement plan,
generally the value of the annuity. The "investment in the contract" generally
equals the portion of any deposits made by or on behalf of an individual under
an annuity which was not excluded from the gross income of the individual. For
annuities issued in connection with qualified plans, the "investment in the
contract" can be zero.

For annuity payments, the taxable portion is generally determined by a formula
that establishes the ratio that the cost basis of the contract bears to the
expected return under the contract. Such taxable part is taxed at ordinary
income rates.

If a taxable distribution is made under the variable annuity contracts, a
penalty tax of 10% of the amount of the taxable distribution may apply. This
additional tax does not apply where the taxpayer is 59 1/2 or older, where
payment is made on account of the taxpayer's disability, or where payment is
made by reason of the death of the owner, and in certain other circumstances.

The Code also provides an exception to the penalty tax for distributions in
periodic payments, of substantially equal installments, be made for the life (or
life expectancy) of the taxpayer or the joint lives (or joint life expectancies)
of the taxpayer and beneficiary.

For some types of qualified plans, other tax penalties may apply to certain
distributions.

A transfer of ownership of a contract, the designation of an annuitant or other
payee who is not also the contract owner, or the assignment of a contract may
result in certain income or gift tax consequences to the contract owner that are
beyond the scope of this discussion. A contract owner who is contemplating any
such transfer, designation or assignment should consult a competent tax adviser
with respect to the potential tax effects of that transaction.

For purposes of determining a contract owner's gross income, the Code provides
that all non-qualified deferred annuity contracts issued by the same company (or
its affiliates) to the same contract owner during any calendar year shall be
treated as one annuity contract. Additional rules may be promulgated under this
provision to prevent avoidance of its effect through serial purchases of
contracts or otherwise. For further information on these rules, see your tax
adviser.

27
<PAGE>
DIVERSIFICATION REQUIREMENTS

Section 817(h) of the Code authorizes the Treasury to set standards by
regulation or otherwise for the investments of the Variable Fund D to be
"adequately diversified" in order for the contract to be treated as an annuity
contract for Federal tax purposes. Variable Fund D, through the Series Fund,
intends to comply with the diversification requirements prescribed in
Regulations Section 1.817-5, which affect how the Series Fund's assets may be
invested. Although the investment adviser is an affiliate of Minnesota Mutual,
Minnesota Mutual does not have control over the Series Fund or its investments.
Nonetheless, Minnesota Mutual believes that each Portfolio of the Series Fund in
which the Variable Fund D owns shares will be operated in compliance with the
requirements prescribed by the Treasury.

In certain circumstances, owners of variable annuity contracts may be considered
the owners, for federal income tax purposes, of the assets of the separate
account used to support their contracts. In those circumstances, income and
gains from the separate account assets would be includable in the variable
annuity contract owner's gross income. The IRS has stated in published rulings
that a variable contract owner will be considered the owner of separate account
assets if the contract owner possesses incidents of ownership in those assets,
such as the ability to exercise investment control over the assets. The Treasury
Department has also announced, in connection with the issuance of regulations
concerning investment diversification, that those regulations "do not provide
guidance concerning the circumstances in which investor control of the
investments of a segregated asset account may cause the investor (i.e., the
contract owner), rather than the insurance company, to be treated as the owner
of the assets in the account." This announcement also states that guidance would
be issued by way of regulations or rulings on the "extent to which policyholders
may direct their investments to particular subaccounts without being treated as
owners of the underlying assets." As of the date of this Prospectus, no such
guidance has been issued.

The ownership rights under the contract are similar to, but different in certain
respects from, those described by the IRS in rulings in which it was determined
that contract owners were not owners of separate account assets. For example,
the owner of a contract has the choice of several sub-accounts in which to
allocate net purchase payments and contract values, and may be able to transfer
among sub-accounts more frequently than in such rulings. These differences could
result in a contract owner being treated as the owner of the assets of Variable
Fund D. In addition, Minnesota Mutual 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. Minnesota Mutual therefore reserves the right to
modify the contract as necessary to attempt to prevent a contract owner from
being considered the owner of a pro rata share of the assets of Variable Fund D.

REQUIRED DISTRIBUTIONS

In order to be treated as an annuity contract for Federal income tax purposes,
Section 72(s) of the Code requires any nonqualified contract issued after
January 18, 1985 to provide that (a) if an owner dies on or after the annuity
starting 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 being used as of the date of that
owner's death; and (b) if an owner dies prior to the annuity starting date, the
entire interest in the contract must be distributed within five years after the
date of the owner's death. These requirements shall be considered satisfied if
any portion of the owner's interest which is payable to or for the benefit of a
"designated beneficiary" is distributed over the life of such beneficiary or
over a period not extending beyond the life expectancy of that beneficiary and
such distributions begin within one year of that owner's death. The owner's
"designated beneficiary" is the person designated by such owner as a beneficiary
and to whom ownership of the contract passes by reason of death and must be a
natural person. However, if the owner's "designated beneficiary" is the
surviving spouse of the owner, the contract may be continued with the surviving
spouse as the new owner.

Nonqualified contracts issued after January 18, 1985 contain provisions which
are intended to comply with the requirements of Section 72(s) of the Code,
although no regulations interpreting these requirements have yet been issued.
Minnesota Mutual intends to review such provisions and modify them if necessary
to assure that they comply with the requirements of Code Section 72(s) when
clarified by regulation or otherwise.

Other rules may apply to qualified contracts.

TAXATION OF DEATH BENEFIT PROCEEDS

Amounts may be distributed from a contract because of the death of the owner.
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.

28
<PAGE>

POSSIBLE CHANGES IN TAXATION

Legislation has been proposed in 1998 that, if enacted, would adversely modify
the federal taxation of certain insurance and annuity contracts. For example,
one proposal would tax transfers among investment options and tax exchanges
involving variable contracts. A second proposal would reduce the "investment in
the contract" under cash value life insurance and certain annuity contracts by
certain amounts, thereby increasing the amount of income for purposes of
computing gain. Although the likelihood of there being any change is uncertain,
there is always the possibility that the tax treatment of the Contracts could
change by legislation or other means. Moreover, it is also possible that any
change could be retroactive (that is, effective prior to the date of the
change). You should consult a tax adviser with respect to legislative
developments and their effect on the Contract.

TAX QUALIFIED PROGRAMS

The annuity is designed for use with several types of retirement plans that
qualify for special tax treatment. The tax rules applicable to participants and
beneficiaries in retirement plans vary according to the type of plan and the
terms and conditions of the plan. Special favorable tax treatment may be
available for certain types of contributions and distributions. 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 minimum distribution rules; aggregate
distributions in excess of a specified annual amount; and in other specified
circumstances.

We make no attempt to provide more than general information about use of
annuities with the various types of retirement plans. Owners and participants
under retirement plans as well as annuitants and beneficiaries are cautioned
that the rights of any person to any benefits under annuities purchased in
connection with these plans may be subject to the terms and conditions of the
plans themselves, regardless of the terms and conditions of the annuity issued
in connection with such a plan. Some retirement plans are subject to transfer
restrictions, distribution and other requirements that are not incorporated into
the annuity or our annuity administration procedures. Owners, participants and
beneficiaries are responsible for determining that contributions, distributions
and other transactions with respect to the annuities comply with applicable law.
Purchasers of annuities for use with any retirement plan should consult their
legal counsel and tax adviser regarding the suitability of the contract.
Purchasers of annuities for use with any retirement plan should consult their
legal counsel and tax adviser regarding the suitability of the contract.

For qualified plans under Section 401(a), 403(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 Owner (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 by the Code), distributions generally must begin no later than April 1
of the calendar year following the calendar year in which the Owner (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 Owner (or plan
participant) reaches age 70 1/2. Roth IRAs under Section 408A do not require
distributions at any time prior to the Owner's death.

PUBLIC SCHOOL SYSTEMS AND CERTAIN TAX EXEMPT ORGANIZATIONS

Under Code Section 403(b), payments made by public school systems and certain
tax exempt organizations to purchase annuity contracts for their employees are
excludable from the gross income of the employee, subject to certain
limitations. However, these payments may be subject to FICA (Social Security)
taxes.

Code Section 403(b)(11) restricts the distribution under Code Section 403(b)
annuity contracts of: (1) elective contributions made in years beginning after
December 31, 1988; (2) earnings on those contributions; and (3) earnings in such
years on amounts held as of the last year beginning before January 1, 1989.
Distribution of those amounts may only occur upon death of the employee,
attainment of age 59 1/2, separation from service, disability, or financial
hardship. In addition, income attributable to elective contributions may not be
distributed in the case of hardship.

INDIVIDUAL RETIREMENT ANNUITIES

Section 408 of the Code permits eligible individuals to contribute to an
Individual Retirement Annuity, hereinafter referred to as an "IRA". Also,
distributions from certain other types of qualified plans may be "rolled over"
on a tax-deferred basis into an IRA. The sale of a Contract for use with an IRA
may be subject to special disclosure requirements of the Internal Revenue
Service. Purchasers of a Contract for use with IRAs will be provided with
supplemental information required by the Internal Revenue Services or other
appropriate agency. Such purchasers will have the right to revoke their purchase
within seven days of the earlier of the establishment of the IRA or their
purchase. A Qualified Contract issued in connection with an IRA will be amended
as necessary to conform to the requirements of the Code. Purchasers should seek
competent advice as to the suitability of the Contract for use with IRAs.

29
<PAGE>

Earnings in an IRA are not taxed until distribution. IRA contributions are
limited each year to the lesser of $2,000 or 100% of the Owner's adjusted gross
income and may be deductible in whole or in part depending on the individual's
income. The limit on the amount contributed to an IRA does not apply to
distributions from certain other types of qualified plans that are "rolled over"
on a tax-deferred basis into an IRA. Amounts in the IRA (other than
nondeductible contributions) are taxed when distributed from the IRA.
Distributions prior to age 59 1/2 (unless certain exceptions apply) are subject
to a 10% penalty tax.

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.

CORPORATE PENSION AND PROFIT-SHARING PLANS AND H.R. 10 PLANS

Code Section 401(a) permits employers to establish various types of retirement
plans for employees, and permits self-employed individuals to establish
retirement plans for themselves and their employees. These retirement plans may
permit the purchase of annuities to provide retirement savings under the plans.
Adverse tax or other legal consequences to the plan, to the participant or to
both may result if this annuity is assigned or transferred to any individual as
a means to provide benefit payments, unless the plan complies with all legal
requirements applicable to such benefits prior to transfer of the annuity.

DEFERRED COMPENSATION PLANS

Code Section 457 provides for certain deferred compensation plans. These plans
may be offered with respect to service for state governments, local governments,
political subdivisions, agencies, instrumentalities and certain affiliates of
such entities, and tax exempt organizations. The plans may permit participants
to specify the form of investment for their deferred compensation account. With
respect to non-governmental Section 457 plans, all investments are owned by the
sponsoring employer and are subject to the claims of the general creditors of
the employer and depending on the terms of the particular plan, the employer may
be entitled to draw on deferred amounts for purposes unrelated to its Section
457 plan obligations. In general, all amounts received under a Section 457 plan
are taxable and are subject to federal income tax withholding as wages.

WITHHOLDING

In general, distributions from annuities are subject to federal income tax
withholding unless the recipient elects not to have tax withheld. Different
rules may apply to payments delivered outside the United States. Some states
have enacted similar rules.

Recent changes to the Code allow the rollover of most distributions from
tax-qualified plans and Section 403(b) annuities directly to other tax-qualified
plans that will accept such distributions and to individual retirement accounts
and individual retirement annuities. Distributions which may not be rolled over
are those which are: (1) one of a series of substantially equal annual (or more
frequent) payments made (a) over the life or life expectancy of the employee,
(b) the joint lives or joint expectancies of the employee and the employee's
designated beneficiary, or (c) for a specified period of ten years or more; (2)
a required minimum distribution; or (3) the non-taxable portion of a
distribution.

Any distribution eligible for rollover, which may include payment to an
employee, an employee's surviving spouse or an ex-spouse who is an alternate
payee, will be subject to federal tax withholding at a 20% rate unless the
distribution is made as a direct rollover to a tax-qualified plan or to an
individual retirement account or annuity. It may be noted that amounts received
by individuals which are eligible for rollover may still be placed in another
tax-qualified plan or individual retirement account or individual retirement
annuity if the transaction is completed within sixty days after the distribution
has been received. Such a taxpayer must replace withheld amounts with other
funds to avoid taxation on the amount previously withheld.

SEE YOUR OWN TAX ADVISER

It should be understood that the foregoing description of the federal income tax
consequences under these contracts is not exhaustive and that special rules are
provided with respect to situations not discussed herein. It should also be
understood that should a plan lose its qualified status, employees will lose
some of the tax benefits described. Statutory changes in the Internal Revenue
Code with varying effective dates, and regulations adopted thereunder may also
alter the tax consequences of specific factual situations. Due to the complexity
of the applicable laws, tax advice may be needed by a person contemplating the
purchase of a variable annuity contract or exercising elections under such a
contract. For further information a qualified tax adviser should be consulted.

LEGAL PROCEEDINGS

There are no pending legal proceedings in which the Variable Fund D is a party.
There are no material pending legal proceedings, other than ordinary routine
litigation incidental to their business, in which Minnesota Mutual, MIMLIC
Management, Advantus Capital or Ascend Financial is a party.

YEAR 2000 COMPUTER PROBLEM

The services provided by Minnesota Mutual to the Separate Account and its
contract owners depend on the smooth functioning of its computer systems. Many
computer software systems in use today cannot distinguish the year 2000 from the
year 1900 because of the way that dates are encoded, stored and calculated. That
failure could have a negative impact on the ability of Minnesota Mutual to
provide services to contract owners. Minnesota Mutual has been actively working
on necessary changes to its computer systems to deal with the year 2000.
Although there can be no assurance of complete success, Minnesota Mutual
believes that it will be able to resolve these issues on a timely basis and that
there will be no material adverse impact on its ability to provide services to
the Separate Account.

In addition, Minnesota Mutual's operations could be impacted by its service
providers' or suppliers' year 2000 efforts. Minnesota Mutual has undertaken an
initiative to assess the efforts of organizations where there is a significant
business relationship; however there is no assurance that Minnesota Mutual will
not be affected by year 2000 problems of other organizations.

INDEPENDENT AUDITORS' REPORT

The Board of Trustees of The Minnesota Mutual Life Insurance Company
and Contract Owners of Minnesota Mutual Variable Fund D:

We have audited the accompanying statements of assets and liabilities of the
Growth, Bond, Money Market, Asset Allocation, Mortgage Securities, Index 500 and
Small Company Segregated Sub-Accounts of Minnesota Mutual Variable Fund D (the
Account) as of December 31, 1997 and the related statements of operations for
the year then ended, the statements of changes in net assets for each of the
years in the two-year period then ended and the financial highlights for periods
presented in footnote (7). These financial statements and the financial
highlights are the responsibility of the Account's management. Our
responsibility is to express an opinion on these financial statements and the
financial highlights 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 and the financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Investments owned at December 31, 1997 were verified by examination
of the underlying portfolios of Advantus Series Fund, Inc. (formerly MIMLIC
Series Fund, Inc.). An audit also includes assessing the accounting principles
used and significant estimates made by management as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the Growth, Bond, Money Market,
Asset Allocation, Mortgage Securities, Index 500 and Small Company Segregated
Sub-Accounts of Minnesota Mutual Variable Fund D at December 31, 1997 and the
results of their operations, changes in their net assets and the financial
highlights for the periods stated in the first paragraph above, in conformity
with generally accepted accounting principles.

as the investment vehicle for its variable annuity contracts and variable
life policies. The Fund is registered under the Investment Company Act of
1940 (as amended) as a diversified, open-end management investment company.
Payments allocated to the Growth, Bond, Money Market, Asset Allocation,
Mortgage Securities, Index 500 and Small Company segregated sub-accounts
are invested in shares of the Growth, Bond, Money Market, Asset Allocation,
Mortgage Securities, Index 500 and Small Company Portfolios of the Fund,
respectively.

Ascend Financial Services, Inc., formerly MIMLIC Sales Corporation, acts as
the underwriter for the Account. Advantus Capital Management, Inc. acts as

assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the
financial statements and the reported amounts of increases and decreases in
net assets resulting from operations during the period. Actual results
could differ from those estimates.

INVESTMENTS IN ADVANTUS SERIES FUND, INC.

Investments in shares of the Fund portfolios are stated at market value
which is the net asset value per share as determined daily by the Fund.
Investment transactions are accounted for on the date the shares are
purchased or sold. The cost of investments sold is determined on the
average cost method. All dividend distributions received from the Fund are
reinvested in additional shares of the Fund and are recorded by the
sub-accounts on the ex-dividend date.

FEDERAL INCOME TAXES

The Account is treated as part of Minnesota Mutual for federal income tax
purposes. Under current interpretations of existing federal income tax
law, no income taxes are payable on investment income or capital gain
distributions received by the Account from the Fund.

CONTRACTS IN ANNUITY PAYMENT PERIOD

Annuity reserves are computed for contracts currently payable using the
Progressive Annuity Mortality Table and an assumed interest rate of 3.5
percent. Charges to annuity reserves for mortality and risk expense are
reimbursed to Minnesota Mutual if the reserves required are less than
originally estimated. If additional reserves are required, Minnesota
Mutual reimburses the Account.

MINNESOTA MUTUAL VARIABLE FUND D

(3) MORTALITY AND EXPENSE AND SALES AND ADMINISTRATIVE SERVICE CHARGES

The mortality and expense charge paid to Minnesota Mutual is computed daily
and is equal, on an annual basis, to .795 percent of the average daily net
assets of the Account.

Sales and administrative service charges, depending upon the type of
contract, may be deducted from the contract owner's contract purchase
payment or contract withdrawal. Total sales and administrative charges
deducted from contract purchase payments or contract withdrawal proceeds
for the years ended December 31, 1997 and 1996 amounted to $3,936 and
$3,111, respectively.

(4) REIMBURSEMENT FROM MINNESOTA MUTUAL FOR EXCESS EXPENSES

Effective October 26, 1990, the contract owners of the Account voted to
reorganize as a unit investment trust under the Investment Company Act of
1940 (as amended). Prior to the reorganization, the Account invested
directly in a diversified portfolio of equity securities. The Account has
seven segregated sub-accounts to which contract owners may allocate their
payments.

Under the Plan of Reorganization, Minnesota Mutual agreed to reimburse the
Account for any increase in expenses paid by the Account as a result of the
reorganization. Prior to the reorganization, the Account was charged an
investment advisory fee equal, on an annual basis, to .265 percent of the
average daily net assets. After the reorganization, the Account no longer
pays an investment advisory fee since it no longer invests directly in a
portfolio of securities. However, contract values that are allocated to
the segregated sub-accounts after the reorganization are invested in Fund
portfolios that pay investment advisory fees as well as other operating
expenses. Investment advisory fees are based on the average daily net
assets of the Fund portfolios at the annual rate of .50 percent for the
Growth, Bond, Money Market, Asset Allocation and Mortgage Securities
Portfolios, .40 percent for the Index 500 Portfolio and .75 percent for the
Small Company Portfolio.

In calculating the accumulation unit value for the Growth segregated
sub-account, Minnesota Mutual has agreed to make an adjustment that will
have the effect of reimbursing the excess of any expenses indirectly
incurred as a result of the investment advisory fee and the operating
expenses incurred by the Growth Portfolio over the .265 percent investment
advisory paid prior to the reorganization. In calculating the accumulation
unit value for the segregated sub-accounts other than Growth, Minnesota
Mutual will make adjustments that, in effect, reimburse the excess of the
investment advisory fees incurred through indirect investment in the Fund
over the .265 percent investment management fee paid prior to the
reorganization. No adjustment will be made for the additional operating
expenses charged to those portfolios. However, in the past nine years
Minnesota Mutual has voluntarily absorbed other operating expenses that
exceed .15 percent on an annual basis for each Fund portfolio.

APPENDIX A

CALCULATION OF ACCUMULATION UNIT VALUES

Calculation of the net investment factor and the accumulation unit value may be
illustrated by the following hypothetical example. Assume the accumulation unit
value of the Variable Fund D Growth Sub-Account on the immediately preceding
valuation period was $6.499041. Assume the following about the Series Fund
Growth Portfolio: (a) the net asset value per share of the Growth Portfolio was
$1.394438 at the end of the current valuation period; (2) the Growth Portfolio
declared a per share dividend and capital gain distribution in the amount of
$.037162 during the current valuation period; and (3) the net asset value per
share of the Growth Portfolio was $1.426879 at the end of the preceding
valuation period.

The gross investment rate for the valuation period would be equal to 1.0033086
(1.394438 plus .037162 divided by 1.426879). The net investment rate for the
valuation period is determined by deducting the total Growth Sub-Account
expenses from the gross investment rate. Total Growth Sub-Account expenses of
.0000162 is equal to .0000315 for mortality and risk expense (the daily
equivalent of .795% assuming 252 valuation dates per year) less .0000093 for the
investment management fee reimbursement (the daily equivalent of .235% assuming
252 valuation dates per year) less .0000060 for the other expense reimbursement
(the daily equivalent of .150% assuming 252 valuation dates per year). The net
investment rate equals 1.0032924 (1.0033086 minus .0000162).

The accumulation unit value at the end of the valuation period would be equal to
the value on the immediately preceding valuation date ($6.499041) multiplied by
the net investment factor for the current valuation period (1.003294), which
produces $6.520438.

CALCULATION OF ANNUITY UNIT VALUES AND VARIABLE ANNUITY PAYMENT

The determination of the annuity unit value and the annuity payment may be
illustrated by the following hypothetical example. Assume that the contract has
been in force for more than ten years so that no deferred sales charge will
apply and that there is no deduction for annuity premium taxes. Assume further
that at the date of his or her retirement, the annuitant has credited to his or
her account 30,000 accumulation units, and that the value of an accumulation
unit on the valuation date next following the fourteenth day of the preceding
month was $1.150000, producing a total value of $34,500. Assume also that the
annuitant elects an option for which the table in the contract indicates the
first monthly payment is $6.57 per $1,000 of value applied; the annuitant's
first monthly payment would thus be 34.500 multiplied by $6.57, or $226.67.

Assume that the annuity unit value on the due date of the first payment was
$1.100000. When this is divided into the first monthly payment, the number of
annuity units represented by that payment is determined to be 206.064. The
value of this same number of annuity units will be paid in each subsequent
month.

Assume further that the accumulation unit value on the valuation date next
following the fourteenth day of the succeeding month is $1.160000. This is
divided by the accumulation unit

A-1
<PAGE>

value on the preceding monthly valuation date ($1.150000) to produce a ratio of
1.008696. Multiplying this ratio by .997137 to neutralize the assumed
investment rate of 3.5% per annum already taken into account in determining
annuity units as described above, produces a result of 1.005808. This is then
multiplied by the preceding annuity unit value ($1.100000) to produce a current
annuity value of $1.106390.

The second monthly payment is then determined by multiplying the fixed number of
annuity units (206.064) by the current annuity unit value ($1.106390), which
produces a second monthly annuity payment of $227.99.

INDEPENDENT AUDITORS' REPORT
The Board of Trustees
The Minnesota Mutual Life Insurance Company

We have audited the accompanying consolidated balance sheets of The Minnesota
Mutual Life Insurance Company and subsidiaries as of December 31, 1997 and
1996, and the related consolidated statements of operations and policyowners'
surplus and cash flows for each of the years in the three-year period ended
December 31, 1997. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated 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 audits 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.
In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of The
Minnesota Mutual Life Insurance Company and subsidiaries as of December 31,
1997 and 1996, and the results of their operations and their cash flows for
each of the years in the three-year period ending December 31, 1997 in
conformity with generally accepted accounting principles.
Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplementary information included
in the accompanying schedules is presented for purpose of additional analysis
and is not a required part of the basic financial statements. Such information
has been subjected to the auditing procedures applied in the audits of the
basic financial statements and, in our opinion, is fairly stated in all
material respects in relation to the basic financial statements taken as a
whole.

THE MINNESOTA MUTUAL LIFE INSURANCE COMPANY AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(1) NATURE OF OPERATIONS

The Minnesota Mutual Life Insurance Company (the Company), both directly and
through its subsidiaries, provides a diversified array of insurance and
financial products and services designed principally to protect and enhance the
long-term financial well-being of individuals and families.
The Company's strategy is to be successful in carefully selected niche
markets, primarily in the United States, while focusing on the retention of
existing business and the maintenance of profitability. To achieve this
objective, the Company has divided its businesses into four strategic business
units which focus on various markets: Individual, Financial Services, Group,
and Pension. Revenues in 1997 for these business units were $854,192,000,
$284,222,000, $232,619,000 and $114,324,000, respectively. Additional revenues
of $185,430,000, were reported by the Company's subsidiaries.
At December 31, 1997, the Company was one of the 12 largest mutual life
insurance company groups in the United States, as measured by total assets. The
Company serves nearly seven million people through more than 4,000 associates
located at its St. Paul headquarters and in 81 general agencies and 43 regional
offices throughout the United States.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation
The accompanying consolidated financial statements have been prepared in
accordance with generally accepted accounting principles (GAAP), which vary in
certain respects from accounting practices prescribed or permitted by state
insurance regulatory authorities. The consolidated financial statements include
the accounts of The Minnesota Mutual Life Insurance Company and its
subsidiaries (collectively, "the Company"). All material intercompany
transactions and balances have been eliminated.
The preparation of financial statements in conformity with GAAP requires
management to make certain estimates and assumptions that affect reported
assets and liabilities, including reporting or disclosure of contingent assets
and liabilities as of the balance sheet date and the reported amounts of
revenues and expenses during the reporting period. Future events, including
changes in mortality, morbidity, interest rates, and asset valuations, could
cause actual results to differ from the estimates used in the financial
statements.

Insurance Revenues and Expenses
Premiums on traditional life products, which include individual whole life and
term insurance and immediate annuities, are credited to revenue when due. For
accident and health and group life products, premiums are credited to revenue
over the contract period as earned. Benefits and expenses are recognized in
relation to premiums over the contract period via a provision for future policy
benefits and the amortization of deferred policy acquisition costs.
Nontraditional life products include individual adjustable and variable life
insurance and group universal and variable life insurance. Revenue from
nontraditional life products and deferred annuities is comprised of policy and
contract fees charged for the cost of insurance, policy administration and
surrenders. Expenses include the portion of claims not covered by and interest
credited to the related policy and contract account balances. Policy
acquisition costs are amortized relative to estimated gross profits or margins.

Deferred Policy Acquisition Costs
The costs of acquiring new and renewal business, which vary with and are
primarily related to the production of new and renewal business, are generally
deferred to the extent recoverable from future premiums or expected gross
profits. Deferrable costs include commissions, underwriting expenses and
certain other selling and issue costs.
For traditional life, accident and health and group life products, deferred
acquisition costs are amortized over the premium paying period in proportion to
the ratio of annual premium revenues to ultimate anticipated

64

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

premium revenues. The ultimate premium revenues are estimated based upon the
same assumptions used to calculate the future policy benefits.
For nontraditional life products and deferred annuities, deferred acquisition
costs are amortized over the estimated lives of the contracts in relation to
the present value of estimated gross profits from surrender charges and
investment, mortality and expense margins.
Deferred acquisition costs amortized were $128,176,000, $125,978,000 and
$104,940,000 for the years ended December 31, 1997, 1996 and 1995,
respectively.

Finance Charge Income and Receivables
Finance charge income represents fees and interest charged on consumer loans.
The Company uses the interest (actuarial) method of accounting for finance
charges and interest on finance receivables. Accrual of finance charges and
interest on the smaller balance homogeneous finance receivables is suspended
when a loan is contractually delinquent for more than 60 days and is
subsequently recognized when received. Accrual is resumed when the loan is
contractually less than 60 days past due. Finance charges and interest is
suspended when a loan is considered by management to be impaired. Loan
impairment is measured based on the present value of expected future cash flows
discounted at the loan's effective interest rate, or as a practical expedient,
at the observable market price of the loan or the fair value of the collateral
if the loan is collateral dependent. When a loan is identified as impaired,
interest previously accrued in the current year is reversed. Interest payments
received on impaired loans are generally applied to principal unless the
remaining principal balance has been determined to be fully collectible. An
allowance for uncollectible amounts is maintained by direct charges to
operations at an amount which management believes, based upon historical losses
and economic conditions, is adequate to absorb probable losses on existing
receivables that may become uncollectible. The reported receivables are net of
this allowance.

Valuation of Investments
Fixed maturity securities (bonds) which the Company has the positive intent and
ability to hold to maturity are classified as held-to-maturity and are carried
at amortized cost, net of write-downs for other than temporary declines in
value. Premiums and discounts are amortized or accreted over the estimated
lives of the securities based on the interest yield method. Fixed maturity
securities which may be sold prior to maturity are classified as available-for-
sale and are carried at fair value.
Equity securities (common stocks and preferred stocks) are carried at fair
value. Equity securities also include initial contributions to affiliated
registered investment funds that are managed by a subsidiary of the Company.
These contributions are carried at the market value of the underlying net
assets of the funds.
Mortgage loans are carried at amortized cost less an allowance for
uncollectible amounts. Premiums and discounts are amortized or accreted over
the terms of the mortgage loans based on the interest yield method. A mortgage
loan is considered impaired if it is probable that contractual amounts due will
not be collected. Impaired mortgage loans are valued at the fair value of the
underlying collateral. Interest income on impaired mortgage loans is recorded
on an accrual basis. However, when the likelihood of collection is doubtful,
interest income is recognized when received.
Fair values of fixed maturity securities and equity securities are based on
quoted market prices, where available. If quoted market prices are not
available, fair values are estimated using values obtained from independent
pricing services which specialize in matrix pricing and modeling techniques for
estimating fair values. Fair values of mortgage loans are based upon discounted
cash flows, quoted market prices and matrix pricing.
Real estate is carried at cost less accumulated depreciation and an allowance
for estimated losses. Accumulated depreciation on real estate at December 31,
1997 and 1996, was $6,269,000 and $5,968,000, respectively.
Policy loans are carried at the unpaid principal balance.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Derivative Financial Instruments
The Company entered into equity swaps in 1996 as part of an overall risk
management strategy. The swaps were used to hedge exposure to market risk on
$400,000,000 of the Company's common stock portfolio. The swaps were based upon
certain stock indices. If, at the time of settlement for a particular swap, the
designated stock index had fallen below a specified level, the counterparty
would pay the Company an amount based upon the decline in the index and the
stock portfolio value protected by the swap. If, at the time of settlement, the
designated stock index had risen, the Company would pay the counterparty an
amount based upon the increase in the index and 25% of the stock portfolio
value protected by the swap. The equity swaps were settled with the
counterparties in August of 1997.
The swaps were carried at fair value, which were based upon dealer quotes.
Changes in fair value were recorded directly in policyowners' surplus. Upon
settlement of the swaps, gains or losses were recognized in income. The Company
realized a loss of approximately $31 million in 1997, upon settlement of these
equity swaps.
The Company began investing in international bonds denominated in foreign
currencies in 1997. The Company uses forward foreign exchange currency
contracts as part of its risk management strategy for international
investments. The forward foreign exchange currency contracts are used to reduce
market risks from changes in foreign exchange rates. These forward foreign
exchange currency contracts are agreements to purchase a specified amount of
one currency in exchange for a specified amount of another currency at a future
point in time at a foreign exchange currency rate agreed upon on the contract
open date. No cash is exchanged at the outset of the contract and no payments
are made by either party until the contract close date. On the contract close
date the contracted amount of the purchased currency is received from the
counterparty and the contracted amount of the sold currency is sent to the
counterparty. These contracts are generally short-term in nature and there is
no material exposure to the Company at December 31, 1997.

Capital Gains and Losses
Realized and unrealized capital gains and losses are determined on the specific
identification method. Write-downs of held-to-maturity securities and the
provision for credit losses on mortgage loans and real estate are recorded as
realized losses.
Changes in the fair value of fixed maturity securities available-for-sale and
equity securities are recorded as a separate component of policyowners'
surplus, net of taxes and related adjustments to deferred policy acquisition
costs and unearned policy and contract fees.

Property and Equipment
Property and equipment are carried at cost, net of accumulated depreciation of
$90,926,000 and $81,962,000 at December 31, 1997 and 1996, respectively.
Buildings are depreciated over 40 years and equipment is generally depreciated
over 5 to 10 years. Depreciation expenses for the years ended December 31,
1997, 1996 and 1995, were $8,965,000, $6,454,000 and $5,941,000, respectively.

Separate Accounts
Separate account assets and liabilities represent segregated funds administered
and invested by the Company for the exclusive benefit of pension, variable
annuity and variable life insurance policyowners and contractholders. Assets
consist principally of marketable securities and both assets and liabilities
are reported at fair value, based upon the market value of the investments held
in the segregated funds. The Company receives administrative and investment
advisory fees for services rendered on behalf of these accounts.
The Company periodically invests money in its separate accounts. The market
value of such investments is included with separate account assets and amounted
to $46,293,000 and $14,882,000 as of December 31, 1997 and 1996, respectively.

THE MINNESOTA MUTUAL LIFE INSURANCE COMPANY AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Policyowner Liabilities
Policy and contract account balances represent the net accumulation of funds
associated with nontraditional life products and deferred annuities. Additions
to the account balances include premiums, deposits and interest credited by the
Company. Decreases in the account balances include surrenders, withdrawals,
benefit payments, and charges assessed for the cost of insurance, policy
administration and surrenders.
Future policy and contract benefits are comprised of reserves for traditional
life, group life, and accident and health products. The reserves were
calculated using the net level premium method based upon assumptions regarding
investment yield, mortality, morbidity, and withdrawal rates determined at the
date of issue, commensurate with the Company's experience. Provision has been
made in certain cases for adverse deviations from these assumptions.
Other policyowner funds are comprised of dividend accumulations, premium
deposit funds and supplementary contracts without life contingencies.

Participating Business
Substantially all of the Company's premium revenues are derived from
participating policies. Dividends and other discretionary payments are declared
by the Board of Trustees based upon actuarial determinations, which take into
consideration current mortality, interest earnings, expense factors, and
federal income taxes. Dividends are recognized as expenses consistent with the
recognition of premiums.

Income Taxes
Current income taxes are charged to operations based upon amounts estimated to
be payable as a result of taxable operations for the current year. Deferred
income tax assets and liabilities are recognized for the future tax
consequences attributable to the differences between financial statement
carrying amounts and income tax bases of assets and liabilities.

Reinsurance Recoverables
Insurance liabilities are reported before the effects of ceded reinsurance.
Reinsurance recoverables represent amounts due from reinsurers for paid and
unpaid benefits, expense reimbursements, prepaid premiums and future policy
benefits.

Reclassifications
Certain 1996 and 1995 financial statement balances have been reclassified to
conform with the 1997 presentation.

impaired loans, due to adequate fair market value of underlying collateral, do
not have an allowance for credit losses.
At December 31, 1996, the recorded investment in mortgage loans that were
considered to be impaired was $6,518,000 before allowance for credit losses.
Included in this amount is $2,225,000 of impaired loans, for which the related
allowance for credit losses is $395,000 and $4,293,000 of impaired loans that,
as a result of adequate fair market value of underlying collateral, do not have
an allowance for credit losses.
In addition to the allowance for credit losses on impaired mortgage loans, a
general allowance for credit losses was established for potential impairments
in the remainder of the mortgage loan portfolio. The general allowance was
$1,500,000 at December 31, 1997 and 1996.
Changes in the allowance for credit losses on mortgage loans were as follows:

In connection with the Company's planned construction of an additional home
office facility in St. Paul, the Company entered into a loan contingency
agreement with the Housing and Redevelopment Authority of the City of Saint
Paul, Minnesota (HRA) in November, 1997. A maximum of $15 million in funds is
available under this loan for condemnation and demolition of the Company's
proposed building site. The note bears interest at a rate of 8.625%, with
principal payments commencing February 2004 and a maturity date of August 2025.
Interest payments are accrued and are payable February and August of each year
commencing February 2001. All principal and interest payments are due only to
the extent of available tax increments. As of December 31, 1997 HRA has drawn
$286,775 on this loan contingency agreement and accrued interest of $1,374.

</TABLE>

Direct installment loans at December 31, 1997 consisted of $83,836,000 of
discount basis loans (net of unearned finance charges) and $99,588,00 of
interest-bearing loans. As of December 31, 1996, discount basis loans amounted
to $93,127,000 and interest-bearing loans amounted to $110,911,000. Direct
installment loans generally have a maximum term of 84 months. Retail
installment notes are principally discount basis, arise from the sale of
household appliances, furniture, and sundry services, and generally have a
maximum term of 48 months. Direct installment loans included approximately $65
million and $69 million of real estate secured loans at December 31, 1997 and
1996, respectively. Revolving credit loans included approximately $24 million
and $23 million of real estate secured loans at December 31, 1997 and 1996,
respectively. Experience has shown that a substantial portion of finance
receivables will be renewed, converted or paid in full prior to maturity.
Principal cash collections of direct installment loans amounted to
$90,940,000, $92,438,000 and $75,865,000 and the percentage of these cash
collections to the average net balances were 47%, 48%, and 47% for the years
ended December 31, 1997, 1996 and 1995, respectively.

All loans deemed to be impaired are placed on a non-accrual status. No
accrued or unpaid interest was recognized on impaired loans during 1997. The
average balances of impaired loans during the year ended December 31, 1997 was
$7,397,000 and $12,793,000, respectively, for installment basis and revolving
credit direct loans.
There were no material commitments to lend additional funds to customers
whose loans were classified as non-accrual at December 31, 1997.

A valuation allowance for deferred tax assets was not considered necessary as
of December 31, 1997 and 1996, because the Company believes that it is more
likely than not that the deferred tax assets will be realized through future
reversals of existing taxable temporary differences and future taxable income.
Income taxes paid for the years ended December 31, 1997, 1996 and 1995, were
$97,721,000, $79,026,000 and $64,390,000, respectively.

======== ======== ========
</TABLE>

The liability for unpaid accident and health claims and claim adjustment
expenses is included in future policy and contract benefits and pending policy
and contract claims on the consolidated balance sheets.
As a result of changes in estimates of claims incurred in prior years, the
accident and health claims and claim adjustment expenses incurred increased
(decreased) by $7,809, $4,821 and ($4,014) in 1997, 1996 and 1995,
respectively. These amounts are the result of normal reserve development
inherent in the uncertainty of establishing the liability for unpaid accident
and health claims and claim adjustment expenses.

(8) EMPLOYEE BENEFIT PLANS

Pension Plans
The Company has noncontributory defined benefit retirement plans covering
substantially all employees and certain agents. Benefits are based upon years
of participation and the employee's average monthly compensation or the agent's
adjusted annual compensation. Plan assets are comprised of mostly stocks and
bonds, which are held in the general and separate accounts of the Company and
administered under group annuity contracts issued by the Company. The Company's
funding policy is to contribute annually the minimum amount required by
applicable regulations. The Company also has an unfunded noncontributory
defined benefit retirement plan, which provides certain employees with benefits
in excess of limits for qualified retirement plans.
Net periodic pension cost for the years ended December 31 included the
following components:

A weighted average discount rate of 7.5% and a weighted average rate of
increase in future compensation levels of 5.3% were used in determining the
actuarial present value of the projected benefit obligation at December 31,
1997 and 1996. The assumed long-term rate of return on plan assets was either
8.5% or 7.5%, depending on the plan.

Profit Sharing Plans
The Company also has profit sharing plans covering substantially all employees
and agents. The Company's contribution rate to the employee plan is determined
annually by the trustees of the Company and is applied to each participant's
prior year earnings. The Company's contribution to the agent plan is made as a
certain percentage, based upon years of service, applied to each agent's total
annual compensation. The Company recognized contributions to the plans during
1997, 1996 and 1995 of $7,173,000, $6,092,000 and $6,595,000, respectively.
Participants may elect to receive a portion of their contributions in cash.

Postretirement Benefits Other than Pensions
The Company also has unfunded postretirement plans that provide certain health
care and life insurance benefits to substantially all retired employees and
agents. Eligibility is determined by age at retirement and years of service
after age 30. Health care premiums are shared with retirees, and other cost-
sharing features include deductibles and co-payments.

Components of net periodic postretirement benefit cost for the years ended
December 31 were as follows:

The discount rate used in determining the accumulated postretirement benefit
obligation for 1997 and 1996 was 7.5%. The 1997 net health care cost trend rate
was 8.5%, graded to 5.5% over 6 years, and the 1996 rate was 9.0%, graded to
5.5% over 7 years.
The assumptions presented herein are based on pertinent information available
to management as of December 31, 1997 and 1996. Actual results could differ
from those estimates and assumptions. For example, increasing the assumed
health care cost trend rates by one percentage point in each year would
increase the postretirement benefit obligation as of December 31,1997 by
$4,323,000 and the estimated eligibility cost and interest cost components of
net periodic postretirement benefit costs for 1997 by $588,000.

(9) SALE OF SUBSIDIARY

On October 1, 1997, the Company sold Minnesota Fire and Casualty Company (MFC),
a wholly owned subsidiary to Harleysville Group, Inc. The Company received net
cash proceeds of approximately $33.5 million from the sale, and realized a gain
of approximately $14.5 million. HomePlus Insurance Company (HomePlus), a
previously wholly owned subsidiary of MFC, was excluded from the sale of
assets. In accordance with the agreement, prior to September 30,1997, MFC made
a distribution of private placement bonds to the Company with an amortized cost
of approximately $4.3 million and transferred all issued and outstanding shares
of HomePlus to the Company. The carrying value of the transferred shares was
approximately $5.8 million. Under an administrative services agreement with
MFC, the Company has retained MFC to provide financial and other services for
HomePlus.

(10) REINSURANCE

In the normal course of business, the Company seeks to limit its exposure to
loss on any single insured and to recover a portion of benefits paid by ceding
reinsurance to other insurance companies. To the extent that a reinsurer is
unable to meet its obligation under the reinsurance agreement, the Company
remains liable. The Company evaluates the financial condition of its reinsurers
and monitors concentrations of credit risk to minimize its exposure to
significant losses from reinsurer insolvencies. Allowances are established for
amounts deemed to be uncollectible.
Reinsurance is accounted for over the life of the underlying reinsured
policies using assumptions consistent with those used to account for the
underlying policies.

(11) FAIR VALUE OF FINANCIAL INSTRUMENTS

The estimated fair value of the Company's financial instruments has been
determined using available market information as of December 31, 1997 and 1996.
Although management is not aware of any factors that would significantly affect
the estimated fair value, such amounts have not been comprehensively revalued
since those dates. Therefore, estimates of fair value subsequent to the
valuation dates may differ significantly from the amounts presented herein.
Considerable judgement is required to interpret market data to develop the
estimates of fair value. The use of different market assumptions and/or
estimation methodologies may have a material effect on the estimated fair value
amounts.
Please refer to Note 2 for additional fair value disclosures concerning fixed
maturity securities, equity securities, mortgages and derivatives. The carrying
amounts for policy loans, cash, short term investments, and finance receivables
approximate the assets' fair values.
The interest rates on the finance receivables outstanding as of December 31,
1997 and 1996, are consistent with the rates at which loans would currently be
made to borrowers of similar credit quality and for the same maturity; as such,
the carrying value of the finance receivables outstanding as of December 31,
1997 and 1996, approximate the fair value for those respective dates.
The fair values of deferred annuities, annuity certain contracts, and other
fund deposits, which have guaranteed interest rates and surrender charges are
estimated to be the amount payable on demand as of December 31, 1997 and 1996
as those investments contracts have no defined maturity and are similar to a
deposit liability. The amount payable on demand equates to the account balance
less applicable surrender charges. Contracts without guaranteed interest rates
and surrender charges have fair values equal to their accumulation values plus
applicable market value adjustments. The fair values of guaranteed investment
contracts and supplementary contracts without life contingencies are calculated
using discounted cash flows, based on interest rates currently offered for
similar products with maturities consistent with those remaining for the
contracts being valued.
Rates currently available to the Company for debt with similar terms and
remaining maturities are used to estimate the fair value of notes payable.

(13) COMMITMENTS AND CONTINGENCIES

The Company is involved in various pending or threatened legal proceedings
arising out of the normal course of business. In the opinion of management, the
ultimate resolution of such litigation will not have a material adverse effect
on operations or the financial position of the Company.
In the normal course of business, the Company seeks to limit its exposure to
loss on any single insured and to recover a portion of benefits paid by ceding
reinsurance to other insurance companies. To the extent that a reinsurer is
unable to meet its obligations under the reinsurance agreement, the Company
remains liable. The Company evaluates the financial condition of its reinsurers
and monitors concentrations of credit risk to minimize its exposure to
significant losses from reinsurer insolvencies. Allowances are established for
amounts deemed uncollectible.
The Company has issued certain participating group annuity and group life
insurance contracts jointly with another life insurance company. The joint
contract issuer has liabilities related to these contracts of $279,978,000 as
of December 31, 1997. To the extent the joint contract issuer is unable to meet
its obligation under the agreement, the Company remains liable.
The Company has long-term commitments to fund venture capital and real estate
investments totaling $139,774,000 as of December 31, 1997. The Company
estimates that $51,300,000 of these commitments will be invested in 1998, with
the remaining $88,474,000 invested over the next four years.
As of December 31, 1997, the Company had committed to purchase bonds and
mortgage loans totaling $109,362,000 but had not completed the purchase
transactions.
At December 31, 1997, the Company had guaranteed the payment of $73,100,000
in policyowner dividends and discretionary amounts payable in 1998. The Company
has pledged bonds, valued at $75,774,000 to secure this guarantee.
The Company is contingently liable under state regulatory requirements for
possible assessments pertaining to future insolvencies and impairments of
unaffiliated insurance companies. The Company records a liability for future
guaranty fund assessments based upon known insolvencies, according to data
received from the National Organization of Life and Health Insurance Guaranty
Association. An asset is recorded for the amount of guaranty fund assessments
paid which can be recovered through future premium tax credits.

ITEM 28. INDEMNIFICATION

The State of Minnesota has an indemnification statute, found at Minnesota
Statutes 300.083, as amended, effective January 1, 1984, which requires
indemnification of individuals only under the circumstances described by the
statute. Expenses incurred in the defense of any action, including attorneys'
fees, may be advanced to the individual after written request by the board of
directors upon receiving an undertaking from the individual to repay any amount
advanced unless it is ultimately determined that he is entitled to be
indemnified by the corporation as authorized by the statute and after a
determination that the facts then known to those making the determination would
not preclude indemnification.

Indemnification is required for persons made a part to a proceeding by reason of
their official capacity so long as they acted in good faith, received no
improper personal benefit and have not been indemnified by another
organization. In the case of a criminal proceeding, they must also have had
no reasonable cause to believe the conduct was unlawful. In respect to other
acts arising out of official capacity: (1) where the person is acting
directly for the corporation there must be a reasonable belief by the person
that his or her conduct was in the best interests of the corporation or; (2)
where the person is serving another organization or plan at the request of
the corporation, the person must have reasonably believed that his or her
conduct was not opposed to the best interests of the corporation. In the
case of persons not directors, officers or policy-making employees,
determination of eligibility for indemnification may be made by a
board-appointed committee of which a director is a member. For other
employees, directors and officers, the determination of eligibility is made
by the Board or a committee of the Board, special legal counsel, the
shareholder of the corporation or pursuant to a judicial proceeding.

The Bylaws of The Minnesota Mutual Life Insurance Company expressly reaffirm
the Company's intention to extend the statutory indemnification with respect
to officers and directors who serve on outside activities such as the
Variable Fund Committee. The Company has extended this same protection to
outside members of the Variable Fund Committee, a power specifically granted
to domestic life insurance companies by the statutory provision.

<PAGE>

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

ITEM 29. PRINCIPAL UNDERWRITERS

(a) The principal underwriter is Ascend Financial Services, Inc. Ascend
Financial Services, Inc. is also the principal underwriter for eleven

Re: Minnesota Mutual Variable Fund D

Post-Effective Amendment No. 16

Gentlepersons:

In my capacity as counsel for The Minnesota Mutual Life Insurance Company
(the "Company"), I have reviewed certain legal matters relating to the Company's
Separate Account entitled Minnesota Mutual Variable Fund D (the "Account") in
connection with Post-Effective Amendment No. 16 to its Registration Statement
on Form N-4. This Post-Effective Amendment is to be filed by the Company and
the Account with the Securities and Exchange Commission under the Securities
Act of 1933, as amended, with respect to certain variable life insurance
policies (Securities and Exchange Commission File No. 2-89208).

Based upon that review, I am of the following opinion:

1. The Account is a separate account of the Company duly created and validly
existing pursuant to the laws of the State of Minnesota; and

2. The issuance and sale of the variable annuity contracts funded by the
Account have been duly authorized by the Company and such contracts, when
issued in accordance with and as described in the currentProspectus
contained in the Registration Statement, and upon compliance with
applicable local and federal laws, will be legal and binding obligations
of the Company in accordance with their terms.

I hereby consent to the filing of this opinion as an exhibit to the Registration
Statement.

Sincerely,

Donald F. Gruber
Assistant General Counsel

Minnesota Mutual INDIVIDUAL RETIREMENT ANNUITY
(IRA) AGREEMENT
SEP, TRADITIONAL IRA AND ROTH-IRA

WHAT DOES THIS AGREEMENT PROVIDE?

This agreement modifies the contract. Provisions are changed before issue. In
the event of a conflict between the provisions of this agreement and the
contract to which it is attached, the provisions of this agreement will control.
These changes will allow its use: (a) with a Simplified Employee Pension
(herein "SEP"); and/or (b) as a Traditional Individual Retirement Annuity under
the Employee Retirement Income Security Act of 1974, as amended (herein "IRA");
and/or (c) as a Roth Individual Retirement Annuity under section 408A of the
Internal Revenue Code (herein "Roth-IRA"). The provisions that apply for
Traditional IRAs generally apply for SEPs, unless otherwise stated.

PURCHASE PAYMENTS

ARE TRADITIONAL IRA PURCHASE PAYMENTS LIMITED?

Yes. Where the annuitant has an IRA, purchase payments may be limited. An
annual cash purchase payment may not exceed the lesser of: (a) the amount of
compensation includible in gross income in any taxable year; or (b) $2,000, or
such other maximum amount as may be allowed by law.

Where an annuitant establishes an IRA along with a lower earning spouse,
purchase payments may be limited. They are also limited if the annuitant is the
lower earning spouse. The cash purchase payments for both annuities and
accounts must then be considered together. They may not exceed the lesser of:
(a) the amount of compensation includible in the working spouse's compensation
includible in gross income in any taxable year; or (b) $4,000, or such other
maximum amount as may be allowed by law. In no event may an annuitant's annual
purchase payment exceed the cash amount of: (a) $2,000; or (b) the maximum
annual contribution allowed for an IRA.

The annuitant's employer may make purchase payments under the annuitant's SEP up
to the lesser of 15% of the annuitant's compensation (exclusive of compensation
in excess of $160,000) or $30,000. Other limits will apply if the annuitant's
IRA is used as part of a salary reduction SEP.

The annuitant, or the annuitant and his or her employer, are responsible for
determining the maximum purchase payments that may be made to an IRA.

ARE ROTH-IRA PURCHASE PAYMENTS LIMITED?

Yes. Where the annuitant has a Roth-IRA, purchase payments may be limited.
Annual purchase payments for all IRAs maintained by the annuitant may not exceed
the lesser of 100% of the annuitant's compensation includible in gross income in
any taxable year or $2,000. The maximum purchase payment that an annuitant may
make to a Roth-IRA will depend on the amount of the annuitant's income. The
maximum annual purchase payment allowed for a Roth-IRA is gradually reduced to
$0 between certain levels of Adjusted Gross Income ("AGI"). Adjusted gross
income is defined in section 408A(c)(3) of the Code and does not include amounts
transferred or rolled over to Traditional IRAs or Roth-IRAs. In accordance with
section 408A(c)(3) of the Code, if an annuitant is single, the $2,000 limit is
phased out between AGI of $95,000 and $110,000; if an annuitant is married and
files a joint federal income tax return, it is phased out between $150,000 and
$160,000; and if an annuitant is married and

Minnesota Mutual 1
<PAGE>

files a separate federal income tax return, it is phased out between $0 and
$10,000.

If an annuitant is married, the maximum purchase payment to the lower-earning
spouse's Spousal Roth-IRA may not exceed the lesser of: (a) 100% of both
spouses' combined compensation minus any Roth-IRA or deductible Traditional IRA
contribution for the spouse with the higher compensation; or (b) $2,000. A
maximum of $4,000 may be contributed to both spouses' Spousal Roth-IRAs.
Purchase payments can be divided between the spouses' IRAs as the annuitant and
his spouse wish, but annual purchase payments to either one of the IRAs may not
exceed $2,000.

DO PURCHASE PAYMENT LIMITATIONS APPLY TO A ROLLOVER TO A ROTH-IRA?

No. However, some individuals are not eligible to make rollover purchase
payments to a Roth-IRA.

A qualified rollover is a rollover contribution from another Roth-IRA or
Traditional individual retirement account or annuity in accordance with sections
408(d)(3), 408A(c)(3)(B), 408A(c)(6) and 408A(e) of the Code. A cash purchase
payment may be the amount received by or on behalf of the annuitant as all or
any portion of a distribution which is a rollover contribution. The
distribution may be one from a Traditional IRA or Roth-IRA, but may not be an
eligible rollover distribution from a tax-exempt employee's trust or a qualified
employee annuity plan.

A rollover or transfer from a Traditional IRA to a Roth-IRA will not be
permitted if the annuitant's AGI for the tax year exceeds $100,000 or if the
annuitant is married and files a separate federal income tax return. A rollover
contribution must be received by us not later than 60 days after the annuitant
receives it.

DO PURCHASE PAYMENT LIMITATIONS APPLY TO A ROLLOVER?

No. Limits on purchase payments to the contract do not apply with a rollover
contribution. A rollover contribution is one within the meaning of sections
408(d)(3), 402(c), 403(a)(4), 403(b)(8), 408A(c)(3)(B), 408A(c)(6), 408A(d)(3)
or 408A(e) of the Internal Revenue Code (herein "Code") or a purchase payment
made in accordance with the terms of a SEP as described in section 408(k) of the
Code. In that case, a cash purchase payment may be the amount received by or on
behalf of an annuitant as all or any portion of a distribution which is a
rollover contribution. The distribution may be one from an individual
retirement account, annuity or bond plan; or an eligible rollover distribution
from a tax-exempt employee's trust; a qualified employee annuity plan; or such
other plan as may be allowed by law. A Roth-IRA, however, may not receive a
rollover contribution directly from any plan other than a Traditional IRA or
another Roth-IRA. In addition, a rollover or transfer from a Traditional IRA to
a Roth-IRA will not be permitted if the annuitant's AGI for the tax year exceeds
$100,000; or if the annuitant is married and files a separate federal income tax
return. A rollover contribution must be received by us not later than 60 days
after the annuitant receives it. A direct rollover payment may be made to us
from the plan making the distribution. A purchase payment may not include
contributions to a tax-qualified plan made by the annuitant as an employee.

MAY THE ANNUITANT ALWAYS MAKE PURCHASE PAYMENTS?

No. We will not accept purchase payments under this contract as of a date the
annuitant is not eligible for a SEP, IRA or Roth-IRA.

Minnesota Mutual 2
<PAGE>

In addition, no additional cash contributions or rollover contributions may be
accepted under the contract if: (a) the owner dies before the distribution of
the entire interest in the contract; and (b) the beneficiary is not the
surviving spouse.

Purchase payments which exceed those allowed for an IRA or Roth-IRA may be
returned. We will send them to the annuitant. Return is without regard to the
provisions of this contract dealing with withdrawals. Excess purchase payments
to a SEP may similarly be returned. We will send them to the payer.

The annuitant has the sole responsibility for determining whether any purchase
payments meet applicable income tax requirements.

DISTRIBUTION PROVISIONS

ARE THERE RULES FOR THE TIMING OF DISTRIBUTIONS FROM AN IRA?

Yes. The distribution of an annuitant's value shall be made in accordance with
the minimum distribution requirements of section 408(b)(3) of the Code and the
regulations thereunder, including the incidental death benefit provisions of
section 1.401(a)(9)-2 of the proposed regulations. All of these rules are
incorporated herein by reference.

The annuitant's accumulation value, or withdrawal value if applicable, must be
distributed or begin to be distributed, by the annuitant's required beginning
date. This is the April 1 following the calendar year in which the annuitant
reaches age 70 1/2. For each succeeding year, a distribution must be made on or
before December 31.

The annuitant or, if applicable, the annuitant's beneficiary, is responsible for
assuring that the required minimum distribution is taken in a timely manner and
that the correct amount is distributed.

ARE THERE RULES FOR THE TIMING OF DISTRIBUTIONS FROM A ROTH-IRA WHILE THE
ANNUITANT IS ALIVE?

No. The rules that apply to Traditional IRAs regarding required distributions
while an annuitant is alive do not apply to Roth-IRAs.

WHAT FORMS OF DISTRIBUTION ARE AVAILABLE FROM AN IRA?

By the required beginning date the annuitant may elect to have the accumulation
value, or withdrawal value if applicable, distributed. It must be in one of the
following forms:

(a) a single sum payment;

(b) equal or substantially equal payments over the life of the annuitant;

(d) equal or substantially equal payments over a specified period that may not
be longer than the annuitant's life expectancy;

(e) equal or substantially equal payments over a specified period that may not
be longer than the joint life and last survivor expectancy of the annuitant
and spouse.

Minnesota Mutual 3

<PAGE>

Options (b), (c), (d), and (e) can be satisfied by an annuity form elected by
the annuitant or by systematic withdrawal.

Payments must be made in periodic payments at intervals of no longer than one
year. In addition, payments must be either nonincreasing or they may increase
only as provided in Q&A F-3 of section 1.401(a)(9)-1 of the Proposed Income Tax
Regulations or such final regulations as adopted.

ARE THERE SPECIAL RULES IF THE ANNUITANT DIES BEFORE THE ENTIRE VALUE IN THE
CONTRACT IS DISTRIBUTED?

Yes. If the annuitant dies on or after the date distributions have begun, the
entire remaining value must be distributed at least as rapidly as under the
method of distribution being used as of the date of the annuitant's death. If
the annuitant dies before distributions have begun, the entire remaining value
must be distributed as elected by the annuitant or, if the annuitant has not so
elected, as elected by the beneficiary or beneficiaries, as follows:

(a) by December 31st of the year containing the fifth anniversary of the
annuitant's death; or

(b) in equal or substantially equal payments over the life or life expectancy
of the designated beneficiary or beneficiaries starting by December 31st of
the year following the year of the annuitant's death. If, however, the
beneficiary is the annuitant's surviving spouse, then this distribution is
not required to begin until later. It must begin by December 31st of the
year in which the annuitant would have turned 70 1/2. Minimum payments to
the surviving spouse will be calculated in accordance with the applicable
regulations.

ARE OTHER OPTIONS AVAILABLE TO A SPOUSE BENEFICIARY?

Yes. In addition to the options discussed above, the spouse beneficiary has
other options. He or she may elect to treat the annuitant's IRA or Roth-IRA as
his or her own. This is done by either: (a) not taking a distribution within
the required time period; or (b) making eligible IRA or Roth-IRA contributions
to it.

If the beneficiary chooses one of these options then he or she is the contract
owner. He or she will assume all rights and privileges under the contract.
This right is available only to the spouse of the annuitant.

HOW ARE LIFE EXPECTANCIES FOR CALCULATING REQUIRED DISTRIBUTIONS DETERMINED?

Life expectancy is computed by use of the expected return multiples in Table V
and VI of section 1.72-9 of the Income Tax Regulations.

Unless otherwise elected by the annuitant prior to the commencement of
distributions or, if applicable, by the surviving spouse where the annuitant
dies before distributions have commenced, life expectancies of an annuitant or
spouse beneficiary shall be recalculated annually for purposes of required
distributions. An election not to recalculate shall be irrevocable and shall
apply to all subsequent years. The life expectancy of a nonspouse beneficiary
shall not be recalculated. Instead, life expectancy will be calculated using
the attained age of such beneficiary during the calendar year in which the
annuitant attains age 70 1/2; and payments for subsequent years shall be
calculated based on such life expectancy reduced by one for each calendar year
which has elapsed since the calendar year life expectancy was first calculated.

Minnesota Mutual 4

<PAGE>

In the case of a Roth-IRA, life expectancy will be calculated using the attained
age of such beneficiary in the calendar year distributions are required to
begin; and payments for subsequent years shall be calculated based on such life
expectancy reduced by one for each calendar year which has elapsed since the
calendar year life expectancy was first calculated.

MAY THE ANNUITANT SATISFY MINIMUM DISTRIBUTION REQUIREMENTS BY RECEIVING A
DISTRIBUTION FROM ANOTHER IRA?

Yes. An annuitant may satisfy the minimum distribution requirements under
sections 408(a)(6) and 408(b)(3) of the Code by receiving a distribution from
one IRA that is equal to the amount required to satisfy the minimum distribution
requirements for two or more IRAs. For this purpose, the owner of two or more
IRAs may use the "alternative method" described in Notice 88-38, to satisfy the
minimum distribution requirements described above.

WITHDRAWAL BENEFITS

ARE THERE LIMITS ON WITHDRAWALS FROM AN IRA?

Yes. These limits apply to a partial withdrawal or a surrender of the contract
before the annuitant's age 59 1/2. In that case, we must receive notice of the
intended disposition of the proceeds. This will not apply if the annuitant dies
or is disabled.

ARE ALL WITHDRAWALS FROM ROTH-IRAS SUBJECT TO FEDERAL INCOME TAX?

No. Purchase payments to Roth-IRAs are not deductible. Any partial withdrawal
or surrender of the contract that includes a return of the annuitant's purchase
payment(s) will not be taxable to the extent it is attributable to the purchase
payment(s). Earnings on the purchase payment(s) that are withdrawn are subject
to income tax if withdrawn within 5 years of the annuitant's first contribution
to a Roth-IRA or within 5 years of a rollover purchase payment. In addition,
earnings will be subject to income tax if withdrawn before the annuitant reaches
age 59 1/2; unless the earnings are being withdrawn because of the annuitant's
death or disability or to pay first-time home buyer expenses. If a withdrawal
is made, we must receive notice of the reason for withdrawal or intended
disposition of the proceeds. Income tax will also not apply to distributions
made if the amount received is in excess of the allowed contribution and
returned to the annuitant before the required tax return filing date for that
year, together with any earned interest; or if the entire contract is received
and reinvested in a similar plan entitled to similar tax treatment.

MAY TAX PENALTIES APPLY FOR WITHDRAWALS FROM AN IRA?

Yes. If a withdrawal or surrender occurs before the annuitant is age 59 1/2,
the annuitant may be subject to tax penalties. These penalties are imposed
under the Code. The annuitant may not be subject to tax penalties on amounts
received before age 59 1/2 if: (1) the annuitant becomes disabled as defined by
the Code; (2) the amount received is in excess of the allowed deduction and
returned to the annuitant before the required tax return filing date for that
year, together with any earned interest; or (3) if the entire amount in the
contract is received and reinvested in a similar plan entitled to similar tax
treatment. Additional exceptions to tax penalties may be available to the
annuitant.

We will not be liable for any tax penalties under this contract. We are not
liable for penalties on amounts received or paid by us under this contract.

Any transaction treated by law as a contract distribution may be treated by us
as a complete contract surrender.

MAY TAX PENALTIES APPLY FOR WITHDRAWALS FROM ROTH-IRAS?

Yes. Certain tax penalties are imposed under the Code. If the annuitant owes
income tax on the amount withdrawn, the annuitant will also generally be subject
to a 10% premature withdrawal tax penalty on the amount on which the annuitant
paid income tax. However, the tax penalties will not apply if earnings in the
Roth-IRA are withdrawn within 5 years of the annuitant's first contribution to a
Roth-IRA or within 5 years of a rollover purchase payment from a Traditional IRA
if the distribution is: (1) made on or after the date on which the annuitant
attains age 59 1/2; (2) made because of the annuitant's disability or death; or
(3) made because the amount received was in excess of the allowed contribution
and returned to the annuitant before the required tax return filing date for
that year, together with any earned interest. In addition, the tax penalty will
not apply to a distribution if the entire contract is received and reinvested in
a similar plan entitled to similar tax treatment. Additional exceptions to tax
penalties may be available to the annuitant.

We will not be liable for any tax penalties under this contract. We are not
liable for penalties on amounts received or paid by us under this contract. Any
transaction treated by law as a contract distribution may be treated by us as a
complete contract surrender.

her beneficiaries.

HOW WILL DIVIDENDS BE APPLIED?

Minnesota Mutual INDIVIDUAL RETIREMENT ANNUITY
SIMPLE - (IRA) AGREEMENT

WHAT DOES THIS AGREEMENT PROVIDE?

PURCHASE PAYMENTS

ARE SIMPLE-IRA PURCHASE PAYMENTS LIMITED?

Yes. Where the annuitant's employer establishes a SIMPLE-IRA, purchase payments
may be limited. The annual cash purchase payments must be the lesser of: (a)
an amount equal to 100% of the compensation included in gross income in any
taxable year; or (b) $6,000, or such other maximum amount as may be allowed by
law. Mandated employer purchase payments, in addition to your purchase
payments, can range from 0% to 3% of your annual compensation.

DO PURCHASE PAYMENT LIMITATIONS APPLY TO A ROLLOVER?

No. Limits on purchase payments to the contract do not apply with a rollover
contribution. A rollover contribution is one within the meaning of sections
408(d)(3)(G) of the Internal Revenue Code (herein "Code") or a purchase payment
made in accordance with the terms of a SIMPLE-IRA as described in section 408(p)
of the Code. In that case, a cash purchase payment may be the amount received
by or on behalf of an annuitant as all or any portion of a distribution which is
a rollover contribution. The distribution may be one as allowed by law. A
rollover contribution must be received by us not later than 60 days after the
annuitant receives it. A direct rollover payment may be made to us from the
plan making the distribution. A purchase payment may not include contributions
to a tax-qualified plan made by the annuitant as an employee.

MAY THE ANNUITANT ALWAYS MAKE PURCHASE PAYMENTS?

No. We will not accept purchase payments under this contract as of a date the
annuitant is not eligible for a SIMPLE-IRA.

Purchase payments which exceed those allowed for a SIMPLE-IRA may be returned.
We will send them to the payer. Return is without regard to the provisions of
this contract dealing with withdrawals.

DISTRIBUTION PROVISIONS

ARE THERE RULES FOR THE TIMING OF DISTRIBUTIONS?

Minnesota Mutual 1

<PAGE>

WHAT FORMS OF DISTRIBUTION ARE AVAILABLE?

By the required beginning date the annuitant may elect to have the accumulation
value, or withdrawal value if applicable, distributed. It must be in one of the
following forms:

(a) a single sum payment;

(b) equal or substantially equal payments over the life of the annuitant;

(d) equal or substantially equal payments over a specified period that may not
be longer than the annuitant's life expectancy;

(e) equal or substantially equal payments over a specified period that may not
be longer than the joint life and last survivor expectancy of the annuitant
and spouse.

Options (b), (c), (d), and (e) can be satisfied by an annuity form elected by
the annuitant or by systematic withdrawal.

ARE THERE SPECIAL RULES IF THE ANNUITANT DIES BEFORE THE ENTIRE VALUE IN THE
CONTRACT IS DISTRIBUTED?

(a) by December 31st of the year containing the fifth anniversary of the
annuitant's death; or

ARE OTHER OPTIONS AVAILABLE TO A SPOUSE BENEFICIARY?

Yes. In addition to the options discussed above, the spouse beneficiary has
other options. He or she may elect to treat the annuitant's IRA as his or her

Minnesota Mutual 2

<PAGE>

own. This is done by either: (a) not taking a distribution within the required
time period; or (b) making eligible IRA contributions to it.

HOW ARE LIFE EXPECTANCIES FOR CALCULATING REQUIRED DISTRIBUTIONS DETERMINED?

Life expectancy is computed by use of the expected return multiples in Table V
and VI of section 1.72-9 of the Income Tax Regulations.

Unless otherwise elected by the annuitant prior to the commencement of
distributions or, if applicable, by the surviving spouse where the annuitant
dies before distributions have commenced, life expectancies of an annuitant or
spouse beneficiary shall be recalculated annually for purposes of required
distributions. An election not to recalculate shall be irrevocable and shall
apply to all subsequent years. The life expectancy of a nonspouse beneficiary
shall not be recalculated. Instead, life expectancy will be calculated using
the attained age of such beneficiary during the calendar year in which the
annuitant attains age 70 1/2, and payments for subsequent years shall be
calculated based on such life expectancy reduced by one for each calendar year
which has elapsed since the calendar year life expectancy was first calculated.
