                                                                          PAGE 1

THIS SYNOPSIS CONTAINS A BRIEF SUMMARY OF SOME OF THE IMPORTANT
FEATURES OF THE VARIABLE ANNUITY CONTRACTS DESCRIBED IN THIS
PROSPECTUS.

QUESTIONS AND ANSWERS ABOUT
THE VARIABLE ANNUITY CONTRACT

WHAT IS AN ANNUITY?

An annuity is a series of payments by an insurance company to an "annuitant".
These payments may be made for the life of the annuitant; for life with a
minimum number of payments guaranteed; for the joint lifetime of the annuitant
and another person; or for a specified period of time. An annuity with payments
of a guaranteed amount is a fixed annuity. An annuity with payments which vary
with the investment experience of a separate account is a variable annuity.

WHAT TYPE OF CONTRACT IS OFFERED BY THIS PROSPECTUS?

Two types of variable annuity contracts are offered, a flexible payment deferred
variable annuity contract and a single payment deferred variable annuity. Both
provide for monthly annuity payments which begin either immediately or at a
future date you specify. According to your instructions we allocate your
purchase payments to the General Account, where they receive principal and
interest guarantees, or to Variable Fund D. Variable Fund D invests in one or
more portfolios of Advantus Series Fund, Inc. which do not receive principal or
interest guarantees.

WHAT INVESTMENT OPTIONS ARE AVAILABLE?

Any purchase payments you allocate to Variable Fund D are invested exclusively
in shares of one or more Fund Portfolios. We reserve the right to add, combine
or remove other eligible Funds and Portfolios.

The available Portfolios of Advantus Fund are:

      Growth Portfolio
      Bond Portfolio
      Money Market Portfolio
      Asset Allocation Portfolio
      Mortgage Securities Portfolio
      Index 500 Portfolio
      Small Company Growth Portfolio

There is no assurance that any Portfolio will meet its objectives. Detailed
information about the investment objectives and policies of the Portfolios can
be found in the current prospectus for the Fund attached to this Prospectus. You
should carefully read the Fund prospectus before purchasing in the contract.

                                                                          PAGE 2
<PAGE>
CAN YOU CHANGE THE PORTFOLIO(S) THAT YOU SELECT?

Yes. You can change your allocation of future purchase payments by giving us
written notice or a telephone call notifying us of the change. Before annuity
payments begin, you may transfer all or a part of your accumulation value
between and among the Portfolios and General Account. After annuity payments
begin, you may instruct us to transfer amounts held as annuity reserves among
the variable annuity sub-accounts, subject to some restrictions. Annuity
reserves may be transferred only from a variable annuity to a fixed annuity
during the annuity period. There is currently no charge for transfers, however
we reserve the right to impose such a charge in the future.

ARE THERE PURCHASE PAYMENT LIMITATIONS?

Yes. The minimum purchase payment for a Single Payment Deferred Variable Annuity
Contract is $5,000 and may not exceed $250,000 without our consent. The minimum
purchase payment for the Flexible Payment Deferred Annuity Contract is $25.00.
We currently waive the minimum for the Flexible Payment Deferred Annuity
Contract.

WHAT CHARGES ARE ASSOCIATED WITH THE CONTRACT?


We deduct a daily charge equal to an annual rate of .795% of the net asset value
of Variable Fund D for our mortality and expense risk guarantees. To the extent
that the charge exceeds .795%, we will make a reimbursement to Variable Fund D
contracts.


Under the Flexible Payment Deferred Variable Annuity Contract a deferred sales
charge of up to 9.0% of purchase payments may apply is you make partial
withdrawals or surrender your contract within 10 or fewer years after your last
purchase payment. Under the Single Payment Deferred Immediate Annuity Contract a
deferred sales charge of up to 6.0% of the purchase payment may apply if you
make partial withdrawals or surrender your contract within 10 or fewer years
after your last purchase payment. A portion of the sales charge may be used to
pay distribution expenses. The principal underwriter may pay an amount not to
exceed 6% of the purchase payments received for the Flexible Payment Deferred
Variable Annuity Contracts; or, 3.75% for the Single Payment Deferred Variable
Annuity Contracts.

Deductions for any applicable premium taxes may also be made (currently such
taxes range from 0.0% to 3.5%) depending upon applicable law.


The Portfolio pays investment advisory and other expenses. Total expenses of the
Portfolios range from .42% to .95% of average daily net assets of the Portfolio
on an annual basis. To the extent total expense of Growth Portfolio exceeds
 .265%, Minnesota Life will make a reimbursement to Variable Fund D contracts.



We reserve the right to assess a $100 fee to cover administrative expenses if
you choose to exchange your contract for another of our variable annuity
contracts.


CAN YOU MAKE PARTIAL WITHDRAWALS FROM THE CONTRACT?

Yes. Subject to limitations imposed by the retirement plan or program, you may
make withdrawals of the accumulation value of your contract before an annuity
begins. Your requests for partial withdrawals must be in writing.

                                                                          PAGE 3
<PAGE>

Partial withdrawals are generally subject to the deferred sales charge. In
addition, a penalty tax on the amount of the taxable distribution may be
assessed upon withdrawals from the variable annuity contract in certain
circumstances, including distributions made prior to the contract owner's
attainment of age 59 1/2.


DO YOU HAVE A RIGHT TO CANCEL YOUR CONTRACT?

Yes. You may cancel your contract any time within ten days of receiving it by
returning it to us or your agent. In some states, the free look period may be
longer than ten days. For example, California's free look period is thirty days.
These rights are subject to change and may vary among the states.


WHAT IF THE CONTRACT OWNER OR ANNUITANT DIES?



If the contract owner dies before annuity payments begin, we will pay the death
benefit to the beneficiary named in the contract application. The death benefit
payable to the beneficiary upon the death of the contract owner during the
accumulation period is equal to the greater of:


    -  the amount of the accumulation value payable at death; or

    -  the total amount of your purchase, less all partial withdrawals.

If the annuitant dies after annuity payments have begin, we will pay whatever
death benefit may be called for by the terms of the annuity option selected. If
the owner of this contract is not a natural person, such as a trust or other
similar 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
commencement of annuity payments.

WHAT ANNUITY OPTIONS ARE AVAILABLE?

The annuity options available are

    -  a life annuity

    -  a life annuity with a period certain of either 120 months, 180 months or
       240 months

    -  a joint and last survivor annuity

    -  a period certain annuity

Each annuity option may be elected as either a variable annuity or fixed annuity
or a combination of the two. Other annuity options may be available from us on
request.

WHAT VOTING RIGHTS DO YOU HAVE?

Contract owners and annuitants will be able to direct us as to how to vote
shares of the Fund held for their contracts where shareholder approval is
required by law in the affairs of the Fund.

                                                                          PAGE 4

CONDENSED FINANCIAL INFORMATION AND FINANCIAL STATEMENTS



The financial history of each sub-account may be found in "Appendix A --
Condensed Financial Information". The complete financial statements of Variable
Fund D and Minnesota Life Insurance Company are included in the Statement of
Additional Information.


GENERAL DESCRIPTIONS

A. MINNESOTA LIFE INSURANCE COMPANY


We are Minnesota Life Insurance Company ("Minnesota Life"), a life insurance
company organized under the laws of Minnesota. Minnesota Life was formerly known
as The Minnesota Mutual Life Insurance Company ("Minnesota Mutual"), a mutual
life insurance company organized in 1880 under the laws of Minnesota. On
October 1, 1998, a plan of reorganization created a mutual insurance holding
company named Minnesota Mutual Companies, Inc. Minnesota Mutual reorganized as a
stock insurance company subsidiary of the new holding company and took the name
Minnesota Life. Our home office is at 400 Robert Street North, St. Paul,
Minnesota 55101-2098, telephone: (651) 665-3500. We are licensed to do a life
insurance business in all states of the United States (except New York where we
are an authorized reinsurer), the District of Columbia, Canada, Puerto Rico and
Guam.


B. VARIABLE FUND D

We established Variable Fund D on October 16, 1967 in accordance with Minnesota
Law. 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 assets of Variable Fund D shall not be chargeable with liabilities arising
out of any other business which Minnesota Life may conduct, but shall be held
and applied exclusively for the benefit of the holders of those variable annuity
contracts for which Variable Fund D was established. The investment performance
of 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 our
general corporate obligations.


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
sub-accounts, each investing its assets solely in the shares of one 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 Variable Fund D by the Commission.


                                                                         PAGE 16
<PAGE>
C. ADVANTUS SERIES FUND, INC.


The Advantus Series Fund, Inc. ("Series Fund") is a mutual fund advised by
Advantus Capital. The Series Fund issues its shares only to us and our separate
accounts. It may be offered to separate accounts of insurance companies
affiliated with us in the future. Advantus Capital is a wholly-owned subsidiary
of Minnesota Life. Advantus Capital has retained Credit Suisse Asset Management,
LLC to sub-advise the Small Company Growth Portfolio.


A prospectus for the Series Fund is attached to this Prospectus. You should
carefully read the prospectuses before investing in the Contract.

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 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 Variable Fund D and we reserve
the right to add, combine or remove any sub-accounts of 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 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 Variable
Fund D under the Investment Company Act of 1940, to restrict or eliminate any
voting rights of the contract owners, and to combine Variable Fund D with one or
more of our other separate accounts.

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 Life 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.

                                                                         PAGE 17

CONTRACT DEDUCTIONS

SALES CHARGES

No sales charge is deducted from the purchase payments for these contracts.
However, a deferred sales charge, may apply in certain circumstances.

A 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.

</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, we 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.


A deferred sales charge will apply 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, we will waive the
deferred sales charge on certain amounts of a contract's accumulation value
which is applied to the purchase of an Adjustable Income Annuity, which is an
immediate variable annuity contracts, issued by us (please see the Adjustable
Income Annuity prospectus for details). We will also waive the sales charge on
amounts withdrawn because of an excess contribution to a tax-qualified contract
(including for example individual retirement annuities).


To the extent that sales charges are insufficient to recover sales expenses, we
will pay sales expenses from our 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 0.0% to 3.5%) depending upon
the applicable law.


                                                                         PAGE 19
<PAGE>
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. Variable Fund D is now a unit investment trust rather than a managed
investment company, and therefore 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 .45%, on an annual basis, for the Growth Portfolio
and .30%, .25%, .35%, .30%, .12%, and .65% for the Bond, Money Market, Asset
Allocation, Mortgage Securities, Index 500, and Small Company Growth Portfolios,
respectively) and do incur other operating expenses. Prior to May 1, 2000 those
other operating expenses were voluntarily subsidized by us to the extent that
the expenses exceed .15% on an annual basis for any Portfolio. After May 1, 2000
Advantus Capital has agreed to voluntarily subsidize expenses exceeding .15% on
an annual basis for these Portfolios. Advantus Capital and Minnesota Life are
under no obligation to continue it this practice.



To ensure that Contract Owners and Participants continue to get at least what
they originally expected under their contracts, we have agreed that, each
valuation period, in calculating the net investment factor for the Growth
Sub-Account of Variable Fund D, we 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 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, we will not make adjustments or reimburse the
excess of the investment advisory fees and the operating expenses incurred
through indirect investment in the Series Fund Portfolios and the former .265%
investment management fee. To the extent that a Contract Owner or Participant
chooses to take advantage of Variable Fund D sub-accounts other than the Growth
Sub-Account, you will incur additional expenses.


MORTALITY AND EXPENSE RISKS

We assume the mortality risk under the contract by our obligation to continue to
make monthly annuity payments, to each annuitant regardless of how long you live
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.

We assume 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.

To the extent that sales charges are insufficient to recover sales expenses, we
will pay sales expenses from our other assets or surplus. These assets may
include proceeds from the mortality and expense risks charge described below.

                                                                         PAGE 20
<PAGE>
For assuming these risks, we currently make a deduction from Variable Fund D at
an annual rate of .1325% for the mortality risk and .6625% for the expense risk.
These deductions may be increased or decreased by resolution of the Board of
Directors of Minnesota Life, but not more often than annually. 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 us. Conversely, if the deductions provide more than
sufficient, any excess will be profit to us.

PORTFOLIO CHARGES

Each of the portfolios pays investment advisory and other expenses. A full
discussion of those charges may be found in the attached prospectus for the
Portfolios.

EXPENSES

Variable Fund D has no expenses which are not covered by the deductions listed
above. We perform all the administrative functions relative to the contracts. We
also bear 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, inquiries may be
addressed to us at: Minnesota Mutual Center, 400 Robert Street North, St. Paul,
Minnesota 55101-2098.

1. Types of Contracts

Minnesota Life 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 us. 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.

                                                                         PAGE 21
<PAGE>
    (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
contract owner may be the annuitant or someone else; however, once the contract
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 us at 400 Robert Street North, St.
Paul, Minnesota, of an intention to revoke. If the contract is revoked and
returned, we will refund 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 is extended to thirty
days' time for contracts issued or delivered. These rights are subject to
change, and may vary among other 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 contract owner equal
to the purchase payments will be made by us.


4. Annuity Payments

Variable annuity payments are determined on the basis of:

    -  the mortality table specified in the contract, which reflects the age of
       the annuitant,

    -  the type of annuity payment option selected, and

    -  the investment performance of Variable Fund D.

The amount of the variable annuity payments will not be affected by adverse
mortality experience or by an increase in our 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 reflect investment gains and losses
and investment income of Variable Fund D. Thus the annuity payments will vary
with the investment experience of the assets of Variable Fund D.

5. Modification of the Contract

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

                                                                         PAGE 22
<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 our
prior consent.

The minimum periodic purchase payment which may be made under a Flexible Payment
Deferred Variable Annuity Contract is $25. Currently, we are waiving 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 Variable Fund D or to fairly determine the value of the
     assets of Variable Fund D; or

(c)   such other periods as the Commission may by order permit for the
      protection of the contract owners.

9. Participation

The contract is nonparticipating. Contracts issued prior to October 1, 1998,
were participating.

No assurances can be given as to the amounts, if any, that will be distributed
under participating contracts in the future. When we make any distribution, it
may take the form of additional payments to annuitant or the crediting of
additional accumulation units. We do not anticipate making dividend payments
under these contracts.

VOTING RIGHTS

The Series Fund shares held in Variable Fund D will be voted by us. Shares will
be voted by us in accordance with instructions received from contract owners
with voting interests in each sub-account of 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 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, we will vote such shares of the

                                                                         PAGE 23
<PAGE>
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 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.

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.

While the contracts require that notice of election to begin variable annuity
payments must be received by us at least thirty days prior to the annuity
commencement date, we are currently waiving that requirement for such annuity
elections received at least two valuation days prior to the fifteenth of the
month. We reserve the right to enforce the thirty day notice requirement at our
option at anytime in the future.

Fixed annuity payments are always made as of the first day of a month. The
contracts require that the notice of election to begin fixed annuity payments
must be received by us at least thirty days prior to the annuity commencement
date. However, we are currently waiving this requirement.

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

                                                                         PAGE 24
<PAGE>
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, and 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, we may fulfill our
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. Minnesota
Life is currently waiving this limitation.


Except for Option 4, 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 us.

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 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.

                                                                         PAGE 25
<PAGE>
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:

    -  .997137, and

    -  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 0.0% to 3.5% and are deducted from the
contract value applied to provide annuity payments. We reserve the right to make
such deductions from purchase payments as they are received.


                                                                         PAGE 26
<PAGE>
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 subtracting six
years from your age when applying it to the rates. 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.

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 contract 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 we receive proof of death at our 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 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 contract owner's death. If the annuitant
dies after annuity payments have begun, we will pay to the beneficiary any death
benefit provided by the annuity option selected. The person selected by


                                                                         PAGE 27
<PAGE>

the contract 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 contract owner dies on or before the date on which annuity payments begin
and if the designated beneficiary is a person other than the contract 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 contract owner's death. If there is no
designated beneficiary, then the entire interest in the contract must be
distributed within five years after the contract 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 contract 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 contract owner's written request to change
the beneficiary will not be effective until it is recorded in our home office
records. After it has been recorded, it will take effect as of the date the
contract owner signed the request. However, if the annuitant or the contract
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. We 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.

                                                                         PAGE 28
<PAGE>
The number of accumulation units so determined shall not be changed by any
subsequent change in the value of an accumulation unit. 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.

We 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:

    -  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,

    -  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

    -  customary national business holidays on which the New York Stock Exchange
       is closed for trading.

Accordingly, the value of accumulation units will be determined daily, and such
determinations will be applicable to all purchase payments received by us at our
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 Variable Fund D, the contracts also provide for allocation of
purchase payments to our 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 Variable Fund D or among the sub-accounts of 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 currently waiving this restriction.


The contracts permit us to limit the frequency and amount of transfers from the
General Account to Variable Fund D sub-accounts. Currently, except as provided
below, we limit the


                                                                         PAGE 29
<PAGE>

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.


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 this 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 General Account accumulation value
       at the time of transfer. The third situation is in the case where the
       General Account accumulation value is $1000 of less. In that case, we
       will allow a one-time transfer of the entire accumulation value from the
       General Account to Variable Fund D sub-accounts.

    -  The third situation is in the case where the General Account accumulation
       value is $1000 or less. In that case, we will allow a one-time transfer
       of the entire accumulation value from the General Account to 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.

Transfer arrangements may be established to begin on the 10th or 20th of any
month and if a transfer cannot be completed because of a holiday or weekend 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. There is no charge for systematic transfers at this time, however we
reserve the right to impose charges.


As a type of systematic transfer arrangement for certain contracts, we will
offer automatic portfolio rebalancing ("APR") of amounts on a quarterly,
semi-annual and annual basis. Instructions to us must be in whole percentages
totaling 100%. They will be treated as instructions for transfers to and from
the various sub-accounts. Rebalancing instructions will not affect the current
allocation of future contributions; they may differ from those future
allocations and are not limited to any minimum or maximum number of
sub-accounts. There will be no charge for APR transfers. APR is not available
for values in the General Account.


                                                                         PAGE 30
<PAGE>

You or persons authorized by you may also effect transfers, terminate automatic
premium payments, 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.



We 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. 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. For more information on transactions related to your Contract, you may
contact us at 1-800-362-3141. In addition you may be able to contact us or your
registered representative via Internet e-mail through our web site. Please
remember that e-mail is not a valid substitute for a written request that
requires your signature.



The underlying funds may restrict the amounts or frequency of transfers to or
from a sub-account of the separate account in order to protect fund
shareholders.


The interests of contract owners arising from the allocation of purchase
payments or the transfer of contract values to the general assets of Minnesota
Life are not registered under the Securities Act of 1933. Minnesota Life is not
registered as an investment company under the Investment Company Act of 1940.
Accordingly, such interests and Minnesota Life 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 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

                                                                         PAGE 31
<PAGE>
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 the sub-account holding shares
of the Growth Portfolio of the Series Fund shall be adjusted by us. 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, do not 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 us 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 capital gain distribution by such fund if the "ex-dividend" date occurs
during the current valuation period; divided by (3) the 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. 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.

                                                                         PAGE 32
<PAGE>
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
(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 our premium tax liability. In such event, we will pay in addition
to the cash value paid in connection with the surrender or withdrawal, the
lesser of (1) the amount by which our 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 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 Advantus Capital Management, Inc., which in turn is a wholly-owned subsidiary
of Minnesota Life. 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 Life will pay credits
which allow registered representatives (Agents) who are responsible for sales of
the contracts to attend conventions and other meetings sponsored by us or our
affiliates for the purpose of promoting the sale of insurance and/or investment
products offered by us and our affiliates. Such credits may cover the registered
representatives' transportation, hotel accommodations, meals, registration fees
and the like. We may also pay registered representatives additional amounts
based upon their production and the persistency of life insurance and annuity
business placed with us.

                                                                         PAGE 33

FEDERAL TAX STATUS

INTRODUCTION


Our tax discussion in this Prospectus is general in nature and is not intended
as tax advice. You should consult a tax adviser. We make no attempt 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.
We make no representation regarding the likelihood of continuation of current
income tax laws or the current interpretations of the Internal Revenue Service
("IRS"). The contract may be purchased on a non-tax qualified basis or purchased
and used in connection with certain retirement arrangements entitled to special
income tax treatment under section 401(a), 403(b), 408(b), 408A or 457 of the
Code. The ultimate effect of federal income taxes on the amount held under a
contract, on annuity payments, and on the economic benefit to the contract
owner, the annuitant, or the beneficiary(s) may depend on the tax status of the
individual concerned.


We are 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, we pay no federal income tax on income dividends
received by the Variable Fund D or on capital gains arising from the Variable
Fund D's activities. The Variable Fund D is not taxed as a "regulated investment
company" under the Code and we do not anticipate any change in that tax status.

TAXATION OF ANNUITY CONTRACTS IN GENERAL

Section 72 of the Code governs taxation of nonqualified annuities in general and
some aspects of qualified programs. No taxes are generally 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. As a general rule, deferred
annuity contracts held by an entity (such as a corporation or trust) that is not
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.


The taxable portion of payments made in the event of a full surrender of an
annuity is generally the amount in excess of the purchase payments for the
contract. Amounts withdrawn upon a partial surrender 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 withdrawal amount over the purchase payments
made under the contract all taxable amount received under an annuity contract
are subject to tax at ordinary rather than capital gain tax rates.


In the case of a withdrawal under an annuity that is part of a tax-qualified
retirement plan, 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.

                                                                         PAGE 34
<PAGE>
The taxable portion for annuity payments, is generally determined by a formula
that establishes the ratio of the cost basis of the contract to the expected
return under the contract. The taxable part is taxed at ordinary income rates.

The Code imposes a 10% penalty tax on the taxable portion of certain
distributions from annuity contracts. 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


    -  where payment is made by reason of the death of the contract owner


    -  in certain other circumstances

The Code also provides an exception to the penalty tax for distributions, in
periodic payments, of substantially equal installments, where they are 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, a pledge or any interest in a contract as
security for a loan, the designation of an annuitant or other payee who is not
also the contract owner, or the assignment of the contract may result in certain
income or gift tax consequences to the contract owner that are beyond the scope
of this discussion. If you are contemplating such a transfer, pledge,
designation or assignment, you should consult a competent tax adviser about its
potential tax effects.

For purposes of determining a contract owner's gross income, the Code provides
that all nonqualified 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 contracts or
otherwise.

DIVERSIFICATION REQUIREMENTS

Section 817(h) of the Code authorizes the Treasury Department to set standards
by regulation or otherwise for the investments of 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 Fund Portfolios,
intends to comply with the diversification requirements prescribed in
Regulations Section 1.817-5, which affect how the Portfolio's assets may be
invested. Although the investment adviser of Advantus Fund is an affiliate of
ours, we do not control Advantus Fund or the investments of its Portfolios.
Nonetheless, we believe that each Portfolio of Advantus Fund in which the
Variable Fund D owns shares will be operated in compliance with the requirements
prescribed by the Treasury.

Prior to the enactment of Section 817(h), the IRS published several rulings
under which owners of certain variable annuity contracts were treated as owners,
for federal income tax purposes, of the assets held in a 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. However, the continued effectiveness of the
pre-Section 817(h) published rulings is somewhat uncertain. In connection with
its issuance of proposed

                                                                         PAGE 35
<PAGE>
regulations under Section 817(h) in 1986, the Treasury Department announced that
those regulations did 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". While the Treasury's
1986 announcement stated that guidance would be issued on the "extent to which
the policyholders may direct their investments to particular sub-accounts
without being treated as owners of the underlying assets", no such guidance has
been forthcoming.

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. Minnesota Life does not
believe that the ownership rights or a contract owner under the Contract would
result in any contract owner being treated as the owner of the assets of
Variable Fund D. However, Minnesota Life does not know what standards would be
applied if the Treasury Department should proceed to issue regulations or
rulings on this issue. Minnesota Life 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:


    -  if an contract 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 contract owner's death; and



    -  if an contract 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 contract owner's death.



These requirements will be considered satisfied if any portion of the contract
owner's interest which is payable to or for the benefit of a "designated
beneficiary" is distributed over the life of that 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 contract owner's
"designated beneficiary", who must be a natural person is the person designated
by the contract owner as a beneficiary and to whom ownership of the contract
passes by reason of death. If the contract owner's "designated beneficiary" is
the surviving spouse of the contract owner, however, the contract may be
continued with the surviving spouse as the new contract 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. We
intend 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.

                                                                         PAGE 36
<PAGE>
TAXATION OF DEATH BENEFIT PROCEEDS

Death benefits paid upon the death of a contract owner, generally, 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,
or (2) if distributed under an annuity option, they are taxed in the same manner
as annuity payments, as described above.

POSSIBLE CHANGES IN TAXATION

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 contract 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

    -  other specified circumstances


We make no attempt to provide more than general information about the use of
annuities with the various types of retirement plans. The rights of any person
to any benefits under annuity contracts 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 our annuity administration
procedures. Contract Owners, participants and beneficiaries are responsible for
determining that contributions, distributions and other transactions with
respect to the contracts comply with applicable law. If you intend to purchase a
contract for use with any retirement plan you should consult your 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 April 1 of the calendar year following the
calendar year in which the Contract Owner (or plan participant)reaches age
70 1/2 or retires and must be made in a specified form or manner. If the plan
participant is a "5 percent owner" (as defined in the Code), distributions
generally must begin no later than April 1 of the calendar year following the
calendar year in which the Contract Owner (or plan participant) reaches age
70 1/2. For IRAs described in Section 408, distributions generally must commence
no later than April 1 of the calendar year following the calendar year in which
the Contract 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.


                                                                         PAGE 37
<PAGE>
WITHHOLDING

In general, distributions from annuity contracts 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:

    -  one of a series of substantially equal annual (or more frequent) payments
       made:

         -   over the life or life expectancy of the employee,

         -   over the joint lives or joint expectancies of the employee and the
             employee's designated beneficiary, or

         -   for a specified period of ten years or more;

    -  a required minimum distribution; or

    -  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 60 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


The foregoing summary of the federal income tax consequences under these
contracts is not exhaustive. Special rules are provided with respect to
situations not discussed herein. Should a plan lose its qualified status,
employees will lose some of the tax benefits described. Statutory changes in the
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 you should consult a tax adviser.


PERFORMANCE DATA

From time to time Variable Fund D may publish advertisements containing
performance data relating to its sub-accounts. In the case of the Money Market
Sub-Account, Variable Fund D will publish yield or effective yield quotations
for a seven-day or other specified period. In the case of the other
sub-accounts, performance data will consist of average annual total return
quotations for one year, five year and ten year periods and for the period since
the inception of the underlying Portfolios. Such performance data may be
accompanied by cumulative total

                                                                         PAGE 38
<PAGE>
return quotations for the comparable periods. For periods prior to the date of
this Prospectus the quotations will be based on the assumption that the
contracts described herein were issued when the underlying Portfolios first
became available to Variable Fund D under other contracts issued by us. The
Money Market Sub-Account may also quote such average annual and cumulative total
return figures. Performance figures used by Variable Fund D are based on
historical information of the sub-accounts for specified periods, and the
figures are not intended to suggest that such performance will continue in the
future. Performance figures of Variable Fund D will reflect charges made
pursuant to the terms of the contracts offered by this Prospectus and charges of
the underlying fund. More detailed information on the computations is set forth
in the Statement of Additional Information.

APPENDIX B - TYPES OF QUALIFIED PLANS

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:

    -  elective contributions made in years beginning after December 31, 1988;

    -  earnings on those contributions; and

    -  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.


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 contract 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.

                                                                        PAGE B-1
<PAGE>
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 the contracts to accumulate retirement savings under the
plans. Adverse tax or other legal consequences to the plan, to the participant
or to both may result if this 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.

                          PERFORMANCE DATA

CURRENT YIELD FIGURES FOR MONEY MARKET SUB-ACCOUNT

Current annualized yield quotations for the Money Market Sub-Account are based
on the sub-account's net investment income for a seven-day or other specified
period and exclude any realized or unrealized gains or losses on sub-account
securities. Current annualized yield is computed by determining the net change
(exclusive of realized gains and losses from the sale of securities and
unrealized appreciation and depreciation) in the value of a hypothetical account
having a balance of one accumulation unit at the beginning of the specified
period, dividing such net change in account value by the value of the account at
the beginning of the period, and annualizing this quotient on a 365-day basis.
Variable Fund D may also quote the effective yield of the Money Market
Sub-Account for a seven-day or other specified period for which the current
annualized yield is computed by expressing the unannualized return on a
compounded, annualized basis. The yield and effective yield of the Money Market
Sub-Account for the seven-day period ended December 31, 1999 were 4.65% and
4.75%, respectively.

TOTAL RETURN FIGURES FOR ALL SUB-ACCOUNTS

Cumulative total return quotations for sub-accounts represent the total return
for the period since the sub-account became available pursuant to Variable Fund
D's registration statement. Cumulative total return is equal to the percentage
change between the net asset value of a hypothetical $1,000 investment at the
beginning of the period and the net asset value of that same investment at the
end of the period.

The cumulative total return figures published by Variable Fund D relating to the
contracts described in the Prospectus will reflect Minnesota Life's voluntary
absorption of certain Fund expenses described below. The cumulative total
returns for the sub-accounts for the specified periods ended December 31, 1999
are shown in the table below. The figures in parentheses show what the
cumulative total returns would have been had Minnesota Life not absorbed Fund
expenses as described above.

D's registration statement. Average annual total return figures are the average
annual compounded rates of return required for an initial investment of $1,000
to equal the surrender value of that same investment at the end of the period.
The average annual total return figures published by Variable Fund D will
reflect Minnesota Life's voluntary absorption of certain Fund expenses. Prior to
January 1, 1986, the Fund incurred no expenses. During 1986 and from January 1
to March 8, 1987 Minnesota Life voluntarily absorbed all fees and expenses of
any Fund portfolio that exceeded .75% of the average daily net assets of such
Fund portfolio. For the period subsequent to March 9, 1987, Minnesota Life is
voluntarily absorbing the fees and expenses that exceed .65% of the average
daily net assets of the Growth, Bond, Money Market, Asset Allocation and
Mortgage Securities Portfolios of the Fund, .55% of the average daily net assets
of the Index 500 Portfolio of the Fund, and .90% of the average daily net assets
of the Small Company Growth Portfolio. Advantus Capital Management, Inc.
("Advantus Capital") intends to waive other fund expenses during the current
fiscal year which exceed, as a percentage of average daily net assets .15%.
There is no specified or minimum period of time during which it has agreed to
continue its voluntary absorption of these expenses, and may in its
discretion cease its absorption of these expenses at any time. Should
Advantus Capital cease absorbing expenses, the effect would be to increase
substantially fund expenses and thereby reduce investment return. There is no
specified or minimum period of time during which Advantus Capital has agreed
to continue its voluntary absorption of these expenses, and Advantus Capital
may in its discretion cease its absorption of expenses at any time. Should
Advantus Capital cease absorbing expenses the effect would be to increase
Fund expenses and thereby reduce investment return.

The average annual total return figures described above may be accompanied by
other average annual total return quotations for the same or other periods. Such
other average annual total return figures will be calculated as described above.
The average annual rates of return, as thus calculated, for the sub-accounts of
the contracts described in the Prospectus for the specified periods ended
December 31, 1999 are shown in the tables below. They are the same for the
individual accumulation annuity, group accumulation annuity and group deposit
administration contracts. The figures in parentheses show what the average
annual rates of return would have been had Minnesota Life not absorbed Fund
expenses as described above.

                          INDEPENDENT AUDITORS' REPORT




The Board of Trustees of Minnesota Life Insurance Company
  and Contract Owners of 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 Growth Segregated Sub-Accounts of Variable Fund D (the Account),
as of December 31, 1999 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
note (7) to the financial statements. 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, 1999 were verified by examination
of the underlying portfolios of Advantus 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 Growth
Segregated Sub-Accounts of Variable Fund D at December 31, 1999 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.

                                 VARIABLE FUND D

                          NOTES TO FINANCIAL STATEMENTS

(1)    ORGANIZATION

       Variable Fund D (the Account), is organized as a segregated asset account
       of Minnesota Life Insurance Company (Minnesota Life) under Minnesota law
       and is registered as a unit investment trust under the Investment Company
       Act of 1940 (as amended).

       The assets of each segregated sub-account are held for the exclusive
       benefit of the variable annuity contract owners and are not chargeable
       with liabilities arising out of the business conducted by any other
       account or by Minnesota Life. Contract owners allocate their variable
       annuity payments to one or more of the seven segregated sub-accounts.
       Such payments are then invested in shares of Advantus Series Fund, Inc.,
       (the Fund) organized by Minnesota Life 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 Growth segregated sub-accounts are invested
       in shares of the Growth, Bond, Money Market, Asset Allocation, Mortgage
       Securities, Index 500 and Small Company Growth Portfolios of the Fund,
       respectively.

       Ascend Financial Services, Inc. acts as the underwriter for the Account.
       Advantus Capital Management, Inc., a wholly owned subsidiary of Minnesota
       Life, acts as the investment adviser for the Fund. Ascend Financial
       Services, Inc. is a wholly-owned subsidiary of Advantus Capital
       Management, Inc.

(2)    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

       USE OF ESTIMATES

       The preparation of financial statements in conformity with generally
       accepted accounting principles requires management to make estimates and
       assumptions that affect the reported amounts in the financial statements.
       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 Life 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 Life if the reserves required are less than
       originally estimated. If additional reserves are required, Minnesota Life
       reimburses the Account.

                                 VARIABLE FUND D


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

       The mortality and expense charge paid to Minnesota Life 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, 1999 and 1998 amounted to $2,199 and
       $2,249, respectively.

(4)    REIMBURSEMENT FROM MINNESOTA LIFE 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 Life 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 Growth Portfolio.

       In calculating the accumulation unit value for the Growth segregated
       sub-account, Minnesota Life 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 Life 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 ten years Minnesota Life has voluntarily absorbed other
       operating expenses that exceed .15 percent on an annual basis for each
       Fund portfolio.

Independent Auditors' Report

The Board of Directors
Minnesota Life Insurance Company:

   We have audited the accompanying consolidated balance sheets of the
Minnesota Life Insurance Company and subsidiaries as of December 31, 1999 and
1998, and the related consolidated statements of operations and comprehensive
income, changes in stockholder's equity and cash flows for each of the years in
the three-year period ended December 31, 1999. 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 audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

   In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of the
Minnesota Life Insurance Company and subsidiaries as of December 31, 1999 and
1998, and the results of their operations and their cash flows for each of the
years in the three-year period ended December 31, 1999 in conformity with
generally accepted accounting principles.

   Our audits were made for the purpose of forming an opinion on the basic
consolidated 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 consolidated
financial statements. Such information has been subjected to the auditing
procedures applied in the audits of the basic consolidated financial statements
and, in our opinion, is fairly stated in all material respects in relation to
the basic consolidated financial statements taken as a whole.

Minnesota Life Insurance Company and Subsidiaries

Notes to Consolidated Financial Statements
(1) Nature of Operations

Description of Business
Minnesota Life Insurance Company, both directly and through its subsidiaries
(collectively, the Company), 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 five strategic business
units, which focus on various markets: Individual Insurance, Financial
Services, Group Insurance, Pension and Asset Management. Revenues in 1999 for
these business units were $703,473,000, $263,418,000, $388,792,000,
$164,774,000, and $66,594,000, respectively. Additional revenues of
$174,633,000 were reported by the Company's subsidiaries and corporate product
line.
   The Company serves over six million people through more than 4,000
associates located at its St. Paul, Minnesota headquarters and in sales offices
nationwide.

Conversion to a Mutual Holding Company Structure
Consent was given from the Minnesota Department of Commerce (Department of
Commerce) allowing The Minnesota Mutual Life Insurance Company to implement a
conversion to a mutual holding company. The Minnesota Mutual Life Insurance
Company enacted this privilege effective October 1, 1998. The conversion
created Minnesota Mutual Companies, Inc., a mutual holding company, Securian
Holding Company, and Securian Financial Group, Inc., which are intermediate
stock holding companies. The Minnesota Mutual Life Insurance Company was
converted into a stock life insurance company and renamed Minnesota Life
Insurance Company. Minnesota Mutual Companies, Inc. will at all times, in
accordance with the conversion plan and as required by the Mutual Insurance
Holding Company Act, directly or indirectly control Minnesota Life Insurance
Company through the ownership of at least a majority of the voting power of the
voting shares of the capital stock of Minnesota Life Insurance Company. Annuity
contract and life insurance policyholders of Minnesota Life Insurance Company
have certain membership interests consisting primarily of the right to vote on
certain matters involving Minnesota Mutual Companies, Inc. and the right to
receive distributions of surplus in the event of demutualization, dissolution
or liquidation of Minnesota Mutual Companies, Inc.

(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). The
consolidated financial statements include the accounts of the Minnesota Life
Insurance Company and its subsidiaries. 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 consolidated
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.

Minnesota Life Insurance Company and Subsidiaries

Notes to Consolidated Financial Statements (continued)
(2) Summary of Significant Accounting Policies (continued)

   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 both 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
policy acquisition costs are amortized over the premium paying period in
proportion to the ratio of annual premium revenues to ultimate anticipated
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 policy
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 policy acquisition costs amortized were $123,455,000, $148,098,000
and $128,176,000 for the years ended December 31, 1999, 1998 and 1997,
respectively.

Software Capitalization
The Accounting Standards Executive Committee issued Statement of Position 98-1,
Accounting for Costs of Computer Software for Internal Use, effective for
fiscal years beginning after December 15, 1998. The Company has adopted the
capitalization of software cost beginning in 1999. At December 1999, the
Company had unamortized cost of $7,459,000 and amortized software expense of
$1,643,000. Costs are amortized over a three-year period.

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.

(2) Summary of Significant Accounting Policies (continued)

   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.
   On January 1, 1999, the Company converted to the equity method of accounting
for its private equity investments. Prior to 1999 the Company accounted for
these investments using the cost method. The change to this method of
accounting was not material to prior year amounts. Private equity investments
are now carried at our equity in the estimated fair value of the underlying
investments of these limited partnerships. In-kind distributions are recorded
as a return of capital for the cost basis of the stock received. Changes in
fair value are recorded directly in stockholder's equity.
   Fair values of fixed maturity securities, equity securities and private
equities 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, 1999 and 1998, was $7,101,000 and $6,713,000, respectively.
   Policy loans are carried at the unpaid principal balance.

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 1997. The swaps were carried at fair value, which were
based upon dealer quotes. Changes in fair value were recorded directly in
stockholder's equity. Upon settlement of the swaps, gains or losses were
recognized in income, and the Company realized a loss of approximately
$31,000,000 in 1997, upon settlement of these equity swaps.
   The Company began investing in international bonds denominated in foreign
currencies in 1997. Unrealized gains or losses are recorded on foreign
denominated securities due to the fluctuation in foreign currency exchange
rates and/or related payables and receivables and interest on foreign
securities. 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

(2) Summary of Significant Accounting Policies (continued)

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. Realized and unrealized gains and losses on these forward foreign
exchange contracts are recorded in income as incurred. Notional amounts for the
years ended December 31, 1999 and 1998, were $98,606,000 and $115,194,000,
respectively.

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,
equity securities and private equity investments in limited partnerships are
recorded as a separate component of stockholder's equity, 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
$113,441,000 and $101,692,000 at December 31, 1999 and 1998, 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,
1999, 1998 and 1997, were $11,749,000, $10,765,000 and $8,965,000,
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 policyholders 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, included with separate account assets, amounted to
$49,396,000 and $46,946,000 at December 31, 1999 and 1998, respectively.

Policyholders 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 policyholders funds are comprised of dividend accumulations, premium
deposit funds and supplementary contracts without life contingencies.

Participating Business
Dividends on participating policies and other discretionary payments are
declared by the Board of Directors 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. At December 31, 1999 and 1998, the total
participating business in force was $50,305,164,000 and $55,683,649,000,
respectively.

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 1998 and 1997 consolidated financial statement balances have been
reclassified to conform to the 1999 presentation.

   At December 31, 1999, no mortgage loans were considered impaired. At
December 31, 1998, the recorded investment in mortgage loans that were
considered to be impaired was $8,798, before the allowance for credit losses.
These impaired loans, due to adequate fair market value of underlying
collateral, do not have an allowance for credit losses.
   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, 1999 and 1998.

   Changes in the allowance for credit losses on mortgage loans were as

the extent of available tax increments. As of December 31, 1999 and 1998, HRA
has drawn $13,574,000 and $9,669,000 on this loan contingency agreement and
accrued interest of $1,795,000 and $673,000, respectively.

   The direct installment loans, at December 31, 1999 and 1998, consisted of
$83,376,000 and $81,066,000, respectively, of discount basis loans (net of
unearned finance charges) and $44,003,000 and $66,359,000, respectively, of
interest-bearing loans and generally have a maximum term of 84 months; the
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 $29
million and $44 million of real estate secured loans at December 31, 1999 and
1998, respectively. Revolving credit loans included approximately $3 million
and $16 million of real estate secured loans at December 31, 1999 and 1998,
respectively. Contractual maturities of the finance receivables by year, as
required by the industry audit guide for finance companies, were not readily
available at December 31, 1999 and 1998, but experience has shown that such
information is not significant in that a substantial portion of receivables
will be renewed, converted, or paid in full prior to maturity.
   During the years ended December 31, 1999 and 1998, principal cash
collections of direct installment loans were $57,665,000 and $75,011,000,
respectively, and the percentages of these cash collections to average net
balances were 43% and 47%, respectively. Retail installment notes' principal
cash collections to average net balances were $12,180,000 and $15,990,000,
respectively, and the percentages of these cash collections to average net
balances were 121% and 101%, respectively.

   At December 31, 1999, the recorded investment in certain direct installment
loans and direct revolving credit loans were considered to be impaired. The
balances of such loans at December 31, 1999 and the related allowance for
credit losses were as follows:

</TABLE>

   All loans deemed to be impaired are placed on a non-accrual status. No
accrued or unpaid interest was recognized on impaired loans during 1999. The
average quarterly balance of impaired loans during the year ended December 31,
1999 and 1998, was $5,758,000 and $6,354,000 for installment basis loans and
$6,214,000 and $12,471,000 for revolving credit loans, respectively.
   There were no material commitments to lend additional funds to customers
whose loans were classified as impaired at December 31, 1999.

(6) Income Taxes

Income tax expense varies from the amount computed by applying the federal
income tax rate of 35% to income from operations before taxes. The significant
components of this difference were as follows:

</TABLE>

   A valuation allowance for deferred tax assets was not considered necessary
as of December 31, 1999 and 1998 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, 1999, 1998 and 1997, were
$59,905,000, $91,259,000 and $71,108,000, respectively.
   The Company's tax returns for 1995, 1996, and 1997 are under examination by
the Internal Revenue Service. The Company believes additional taxes, if any,
assessed as a result of these examinations, will not have a material effect on
its financial position.

</TABLE>

   The liability for unpaid accident and health claims, reserve for losses and
claim and loss 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, reserve for losses and claim and loss adjustment
expenses incurred increased by $19,435,000, $14,644,000 and $7,809,000 in 1999,
1998 and 1997, respectively which includes the amortization of discount on
individual accident and health claim reserves of $13,918,000, $14,256,000,
$11,522,000 in 1999, 1998 and 1997, respectively. The remaining changes in
amounts are the result of normal reserve development inherent in the
uncertainty of establishing the liability for unpaid accident and health
claims, reserve for losses and claim and loss adjustment expenses.

(8) Employee Benefit Plans

Pension Plans and Post Retirement Plans Other than Pensions
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.
   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.

(8) Employee Benefit Plans (continued)

   For measurement purposes, an 8.5 percent annual rate of increase in the per
capita cost of covered health care benefits was assumed for 2000. The rate was
assumed to decrease gradually to 5.5 percent for 2005 and remain at that level
thereafter.

   The projected benefit obligation, accumulated benefit obligation, and fair
value of plan assets for the pension plan with accumulated benefit obligations
in excess of plan assets were $45,610,000, $36,376,000 and $18,500,000,
respectively, as of December 31, 1999, and $39,470,000, $31,546,000 and
$17,334,000, respectively, as of December 31, 1998.
   The assumptions presented herein are based on pertinent information
available to management as of December 31, 1999 and 1998. 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, 1999 by
$6,164,000 and the estimated eligibility cost and interest cost components of
net periodic benefit costs for 1999 by $831,000. Decreasing the assumed health
care cost trend rates by one percentage point in each year would decrease the
postretirement benefit obligation as of December 31, 1999 by $4,879,000 and the
estimated eligibility cost and interest cost components of net periodic
postretirement benefit costs for 1999 by $637,000.

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 directors 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
1999, 1998 and 1997 of $6,003,000, $7,145,000 and $7,173,000, respectively.
Participants may elect to receive a portion of their contributions in cash.

(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 lives of the underlying reinsured
policies using assumptions consistent with those used to account for the
underlying policies.
   The effect of reinsurance on premiums for the years ended December 31 was as
follows:

   Reinsurance recoveries on ceded reinsurance contracts were $71,922,000,
$64,174,000 and $58,072,000 during 1999, 1998 and 1997, respectively.
   On January 1, 1999, the Company entered into an agreement to sell its
assumed individual life reinsurance business representing $1,982,509,000 of in
force to RGA Reinsurance Company. The Company received cash of $1,284,000 from
the sale and recognized miscellaneous income of approximately $4,139,000,
representing the gain on the sale.
   On October 1, 1999, the Company entered into an assumption reinsurance
agreement with Fort Dearborn Life Insurance Company. The agreement transfers
401(k) accounts with associated fixed and variable assets of approximately
$260,000,000.

(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, 1999 and 1998.
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, private equities 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,
1999 and 1998, 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,
1999 and 1998, 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, 1999 and 1998
as those investment 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.

(11) Fair Value of Financial Instruments (continued)

   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.

(14) Stock Dividends (continued)

   Dividend payments by Minnesota Life Insurance Company to its parent cannot
exceed the greater of 10% of statutory capital and surplus as of the preceding
year-end or the statutory net gain from operations for the current calendar
year, without prior approval from the Department of Commerce. Based on this
limitation and 1998 statutory results, Minnesota Life Insurance Company could
have paid $168,076,000 in dividends in 1999 without prior approval.

(15) 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 $183,200,000 as
of December 31, 1999. 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 private equities and real
estate investments totaling $147,652,000 as of December 31, 1999. The Company
estimates that $60,000,000 of these commitments will be invested in 2000, with
the remaining $87,652,000 invested over the next four years.
   As of December 31, 1999, the Company had committed to purchase bonds and
mortgage loans totaling $54,130,000 but had not completed the purchase
transactions.
   The Company has a long-term lease agreement for rental space in downtown St.
Paul and other locations. Minimum rental commitments under such leases are as
follows: 2000, $2,400,000; 2001, $2,227,000; 2002, $2,092,000; 2003,
$2,108,000; 2004, $1,261,000; 2005, $22,000.
   At December 31, 1999, the Company had guaranteed the payment of $76,600,000
in policyholders dividends and discretionary amounts payable in 2000. The
Company has pledged bonds, valued at $79,333,000 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. At December 31, 1999 and 1998 the liability was ($352,000) and
$1,105,000, respectively. An asset is recorded for the amount of guaranty fund
assessments paid, which can be recovered through future premium tax credits.
This asset was $5,485,000 and $7,282,000 for the periods ending December 31,
1999 and 1998, respectively. These assets are being amortized over a five-year
period.
   At December 1999, the Company has guaranteed the payment of approximately
$125,000,000 of senior notes issued by Capitol City Properties Management,
Inc., an affiliated company through the expiration date of the notes June 1,
2021 or by mutual agreement of the parties. These notes were issued in
conjunction with the financing of the Company's additional home office space.

                                      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 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 value on the preceding monthly valuation date
($1.150000) to produce a ratio of 1.008696.


                                         A-1

<PAGE>

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.

             Variable Annuity Contracts                 268


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 Minnesota 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
Minnesota Life Insurance Company and Variable Fund D pursuant to the
foregoing provisions, or otherwise, Minnesota Life Insurance Company and
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
Minnesota Life Insurance Company and Variable Fund D of expenses incurred or
paid by a director, officer or controlling person of Minnesota Life Insurance
Company and 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, Minnesota Life Insurance
Company and 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.

                                                     A MINNESOTA MUTUAL COMPANY

Minnesota Life Insurance Company

St. Paul, Minnesota 55101

Gentlepersons:

In my capacity as counsel for Minnesota Life Insurance Company (the
"Company"), I have reviewed certain legal matters relating to the Company's
Separate Account entitled Variable Fund D (the "Fund") in connection with
Post-Effective Amendment No. 19 to its Registration Statement on Form N-4.
This Post-Effective Amendment is to be filed by the Company and the Fund with
the Securities and Exchange Commission under the Securities Act of 1933, as
amended, with respect to certain variable annuity contracts (Securities and
Exchange Commission File No. 2-89208).

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

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

     2.   The issuance and sale of the variable annuity contracts funded by the
     Fund have been duly authorized by the Company and such contracts, when
     issued in accordance with and as described in the current Prospectus
     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,


/s/ Donald F. Gruber

Donald F. Gruber
Assistant General Counsel
