VARIABLE ANNUITY CONTRACT PROSPECTUS
FLEXIBLE PAYMENT VARIABLE ANNUITY CONTRACT
SINGLE PAYMENT VARIABLE ANNUITY CONTRACT
OF MINNESOTA MUTUAL'S VARIABLE ANNUITY ACCOUNT
 
COMBINATION FIXED AND VARIABLE ANNUITY CONTRACTS
FOR PERSONAL RETIREMENT PLANS
 
   
The  individual  variable  annuity  contracts  offered  by  this  Prospectus are
designed for use in connection with personal retirement plans, some of which may
qualify for federal  income tax  advantages available under  sections 401,  403,
408, 408A, or 457 of the Internal Revenue Code. They may also be used apart from
a  qualified plan. Two  different contracts are offered:  (1) a Flexible Payment
Variable Annuity  Contract (no  minimum  initial purchase  payment), and  (2)  a
Single  Payment Variable Annuity  Contract (minimum initial  purchase payment of
$5,000 and may not exceed $250,000, except with our consent).
    
 
  The owner of a  contract may elect  to have contract  values accumulated on  a
completely  variable basis,  on a completely  fixed basis (as  part of Minnesota
Mutual's General Account and in which  the safety of principal and interest  are
guaranteed)  or on a  combination fixed and  variable basis. To  the extent that
contract values are accumulated on a variable basis, they will be a part of  the
Variable  Annuity Account.  The Variable Annuity  Account invests  its assets in
shares of Advantus  Series Fund, Inc.  and Class 2  of the Templeton  Developing
Markets  Fund (the "Funds"). The variable accumulation value of the contract and
the amount of  each variable annuity  payment will vary  in accordance with  the
performance of the Portfolio or Portfolios of the Funds selected by the contract
owner.  The  contract owner  bears the  entire investment  risk for  any amounts
allocated to the Portfolios of the Fund.
 
   
  This Prospectus  sets  forth  concisely the  information  that  a  prospective
investor  should know before  investing in the Variable  Annuity Account, and it
should be  read  and  kept  for future  reference.  A  Statement  of  Additional
Information, bearing the same date, which contains further contract information,
has  been filed with the Securities  and Exchange Commission and is incorporated
by reference  into  this Prospectus.  A  copy  of the  Statement  of  Additional
Information  may be  obtained without  charge by  calling (612)  665-3500, after
September 1,  1998,  (651) 665-3500,  or  by  writing Minnesota  Mutual  at  its
principal  office at Minnesota Mutual Life  Center, 400 Robert Street North, St.
Paul, Minnesota 55101-2098. A Table of Contents for the Statement of  Additional

QUESTIONS AND ANSWERS ABOUT THE VARIABLE ANNUITY CONTRACTS
 
WHAT IS AN ANNUITY?
An  annuity is a series of payments for  life; for life with a minimum number of
payments guaranteed; for the joint lifetime of the annuitant and another  person
and  thereafter during the lifetime of the survivor; or for a period certain. An
annuity with  payments which  are guaranteed  as to  amount during  the  payment
period  is  a fixed  annuity. An  annuity  with payments  which vary  during the
payment period  in  accordance with  the  investment experience  of  a  separate
account is called a variable annuity.
 
WHAT ARE THE CONTRACTS OFFERED BY THIS PROSPECTUS?
The  contracts are  combined fixed and  variable annuity contracts  issued by us
which provide for monthly annuity payments. These payments may begin immediately
or at a future  date elected by  you. Purchase payments received  by us under  a
contract  are  allocated  either  to our  General  Account  or  Variable Annuity
Account, as specified  by you. In  the General Account,  your purchase  payments
receive interest and principal guarantees; in the Variable Annuity Account, your
purchase  payments  are  invested  in  each Fund,  and  receive  no  interest or
principal guarantees.
  This Prospectus describes only the  variable aspects of the contracts,  except
where  fixed aspects are specifically mentioned.  Please look to the language of
the contracts for a description of the fixed portion of the contracts. For  more
information  on the contracts, see the heading "Description of the Contracts" in
this Prospectus.
 
WHAT TYPES OF VARIABLE ANNUITY CONTRACTS ARE AVAILABLE?
We offer two types  of contracts. They are  the single payment variable  annuity
contract and the flexible payment variable annuity contract.
 
WHAT INVESTMENT OPTIONS ARE AVAILABLE FOR THE VARIABLE ANNUITY ACCOUNT?
Purchase  payments allocated to the Variable  Annuity Account may be invested in
shares of each Fund. Each Fund is a mutual fund of the series type, which  means
that  it has several different portfolios which it offers for investment. Shares
of the Fund will be  made available at net asset  value to the Variable  Annuity
Account  to fund the  variable annuity contracts.  The Fund is  also required to
redeem its shares at  net asset value  at our request. We  reserve the right  to
add, combine or remove other eligible funds.
  The  investment  objectives  and certain  policies  of the  Portfolios  of the
Advantus Series Fund are as follows:
      The Growth Portfolio seeks the long-term accumulation of capital.  Current
    income, while a factor in portfolio selection, is a secondary objective. The
    Growth  Portfolio will  invest primarily in  common stocks  and other equity
    securities. Common stocks are more volatile than debt securities and involve
    greater investment risk.
      The Bond Portfolio seeks as high a level of long-term total rate of return
    as is consistent with prudent investment  risk. A secondary objective is  to
    seek  preservation of capital.  The Bond Portfolio  will invest primarily in
    long-term, fixed-income, high-quality  debt instruments. The  value of  debt
    securities  will tend to rise  and fall inversely with  the rise and fall of
    interest rates.
      The Money  Market Portfolio  seeks maximum  current income  to the  extent
    consistent  with liquidity  and the stability  of capital.  The Money Market
    Portfolio will invest in money market instruments and other debt  securities
    with  maturities  not  exceeding  one year.  The  return  produced  by these
    securities will reflect fluctuation in short-term interest rates.
      AN INVESTMENT  IN  THE  MONEY  MARKET PORTFOLIO  IS  NEITHER  INSURED  NOR
    GUARANTEED  BY THE U.S.  GOVERNMENT AND THERE  CAN BE NO  ASSURANCE THAT THE
    PORTFOLIO WILL BE ABLE  TO MAINTAIN A  STABLE NET ASSET  VALUE OF $1.00  PER
    SHARE.
      The  Asset Allocation Portfolio  seeks as high a  level of long-term total
    rate of return  as is  consistent with  prudent investment  risk. The  Asset
    Allocation   Portfolio  will  invest  in  common  stocks  and  other  equity
    securities,  bonds  and  money  market  instruments.  The  Asset  Allocation
    Portfolio  involves  the risks  inherent in  stocks  and debt  securities of
    varying maturities and the  risk that the Portfolio  may invest too much  or
    too little of its assets in each type of security at any particular time.
      The  Mortgage Securities  Portfolio seeks a  high level  of current income
    consistent with prudent investment risk.  In pursuit of this objective,  the
    Mortgage  Securities Portfolio will follow  a policy of investment primarily
    in mortgage-related securities. Prices  of mortgage-related securities  will
 
4
<PAGE>
    tend  to rise and fall inversely with the rise and fall of the general level
    of interest rates.
      The Index 500 Portfolio seeks investment results that correspond generally
    to the price  and yield  performance of the  common stocks  included in  the
    Standard & Poor's Corporation 500 Composite Stock Price Index (the "Index").
    It  is designed to provide an economical and convenient means of maintaining
    a broad  position in  the equity  market as  part of  an overall  investment
    strategy.  All common stocks, including those  in the Index, involve greater
    investment risk  than  debt securities.  The  fact  that a  stock  has  been
    included  in the Index affords no assurance against declines in the price or
    yield performance of that stock.
      The Capital Appreciation  Portfolio seeks growth  of capital.  Investments
    will be made based upon their potential for capital appreciation. Therefore,
    current  income  will  be incidental  to  the objective  of  capital growth.
    Because of the market risks inherent in any equity investment, the selection
    of securities on the basis of their appreciation possibilities cannot ensure
    against possible loss in value.
      The International  Stock  Portfolio  seeks long-term  capital  growth.  In
    pursuit  of this objective, the International  Stock Portfolio will follow a
    policy of investing in stocks issued by companies, large and small, and debt
    obligations of companies and governments outside the United States.  Current
    income  will be incidental to the objective of capital growth. The Portfolio
    is designed  for persons  seeking international  diversification.  Investors
    should  consider carefully  the substantial  risks involved  in investing in
    securities issued by companies and governments of foreign nations, which are
    in addition to the usual risks inherent in domestic investments.
   
      The Small Company  Portfolio seeks long-term  accumulation of capital.  In
    pursuit  of this objective, the Small Company Portfolio will follow a policy
    of investing  primarily  in  common  or preferred  stocks  issued  by  small
    companies,  defined  in  terms  of  either  market  capitalization  or gross
    revenues. Investments in small companies usually involve greater  investment
    risks than fixed income securities or corporate equity securities generally.
    Small  companies will  typically have a  market capitalization  of less than
    $1.5 billion or annual gross revenues of less than $1.5 billion.
    
      The Maturing  Government  Bond  Portfolios  seek to  provide  as  high  an
    investment  return  as  is consistent  with  prudent investment  risk  for a
    specified period of time ending on a specified liquidation date. In  pursuit
    of this objective, each of the four Maturing Government Bond Portfolios seek
    to  return a reasonably  assured targeted dollar  amount, predictable at the
    time of  investment,  on  a  specific target  date  in  the  future  through
    investment  in  a portfolio  composed primarily  of zero  coupon securities.
    These are securities that pay no cash income and are sold at a discount from
    their par value at maturity. The current target dates for the maturities  of
    these  Portfolios are 1998,  2002, 2006 and  2010, respectively. On maturity
    the Portfolio will be converted to  cash and reinvested at the direction  of
    the  contract owner.  In the  absence of  instructions, liquidation proceeds
    will be allocated to the Money Market Portfolio.
   
      The Value Stock Portfolio seeks the long-term accumulation of capital.  In
    pursuit of this objective, the Value Stock Portfolio will follow a policy of
    investing  primarily in  the equity  securities of  companies which,  in the
    opinion of the  adviser, have  market values  which appear  low relative  to
    their  underlying value  or future earnings  and growth potential.  As it is
    anticipated that the Portfolio will consist in large part of dividend-paying
    common stocks, the production of income will be a secondary objective of the
    Portfolio.
    
      The Small  Company Value  Portfolio seeks  the long-term  accumulation  of
    capital.  The Portfolio will  follow a policy of  investing primarily in the
    equity  securities  of   small  companies,  defined   in  terms  of   market
    capitalization and which appear to have market values which are low relative
    to  their underlying value or future earnings and growth potential. Dividend
    income will be incidental to the investment objective for this Portfolio.
   
      The Global Bond Portfolio formerly the International Bond Portfolio  prior
    to  May 1, 1998, seeks to maximize current income consistent with protection
    of principal. The Portfolio pursues its objective by investing primarily  in
    a  managed portfolio  of non-U.S. dollar  debt securities  issued by foreign
    
 
                                                                               5
<PAGE>
    governments, companies and supranational entities.
   
      The Index  400  Mid-Cap  Portfolio seeks  to  provide  investment  results
    generally  corresponding to the aggregate  price and dividend performance of
    publicly traded common stocks  that comprise the Standard  & Poor's 400  Mid
    Cap  Index.  The Portfolio  pursues  its investment  objective  by investing
    primarily in  the 400  common  stocks that  comprise  the Index,  issued  by
    medium-sized  domestic companies with  market capitalizations that generally
    range from  $200  million  to $5  billion.  It  is designed  to  provide  an
    economical  and convenient means  of maintaining a  diversified portfolio in
    this equity security area  as part of an  over-all investment strategy.  The
    inclusion of a stock in the Index in no way implies an opinion by Standard &
    Poor's  as to its attractiveness as an investment, nor is it a sponsor or in
    any way affiliated with the Portfolio.
    
      The Macro-Cap  Value Portfolio  seeks  to provide  high total  return.  It
    pursues   this  objective  by  investing   in  equity  securities  that  the
    sub-adviser believes, through  the use  of dividend discount  models, to  be
    undervalued   relative  to  their  long-term   earnings  power,  creating  a
    diversified portfolio  of  equity securities  which  typically will  have  a
    price/earnings  ratio  and  a price  to  book  ratio that  reflects  a value
    orientation. The Portfolio  seeks to  enhance its total  return relative  to
    that of a universe of large-sized U.S. companies.
      The  Micro-Cap Growth  Portfolio seeks long-term  capital appreciation. It
    pursues its objective by investing primarily in equity securities of smaller
    companies  which  the  sub-adviser  believes  are  in  an  early  stage   or
    transitional  point in their  development and have  demonstrated or have the
    potential for  above average  revenue growth.  It will  invest primarily  in
    common  stocks  and  stock  equivalents  of  micro-cap  companies,  that is,
    companies with a market capitalization of less than $300 million.
   
      The Real Estate Securities Portfolio seeks above-average income and  long-
    term  growth of  capital. The Portfolio  intends to pursue  its objective by
    investing primarily in  equity securities  of companies in  the real  estate
    industry.  The Portfolio seeks to provide a  yield in excess of the yield of
    the Standard & Poor's Corporation 500 Composite Stock Price Index.
    
   
  In addition  to the  investments in  the Advantus  Series Fund,  the  Variable
Annuity  Account invests in the Templeton Developing Markets Fund, a diversified
portfolio with two classes of shares  of the Templeton Variable Products  Series
Fund, a mutual fund of the series type.
    
  The  investment objectives  and certain  policies of  the Templeton Developing
Markets Fund available under the contract are as follows:
      The  Templeton   Developing   Markets   Fund   seeks   long-term   capital
    appreciation.  It pursues  this objective  by investing  primarily in equity
    securities of  issuers in  countries  having developing  markets.  Countries
    generally  considered to have developing markets  are all countries that are
    considered to be developing or emerging countries by the International  Bank
    for  Reconstruction and Development (more commonly  referred to as the World
    Bank) or the International  Finance Corporation, as  well as countries  that
    are  classified  by  the  United  Nations  or  otherwise  regarded  by their
    authorities as developing.
   
  There is  no assurance  that any  Fund will  meet its  objectives.  Additional
information  concerning the investment objectives and policies of the Portfolios
can be found in the current prospectus for each Fund, which is attached to  this
Prospectus.  A  person  should  carefully  read  the  Fund's  prospectus  before
investing in the contract.
    
 
CAN YOU CHANGE THE PORTFOLIO SELECTED?
Yes. You may  change your allocation  of future purchase  payments by giving  us
written  notice  or a  telephone call  notifying  us of  the change.  And before
annuity payments begin,  you may  transfer all or  a part  of your  accumulation
value  from  one Portfolio  to another  or among  the Portfolios.  After annuity
payments begin, transfers may be made with respect to variable annuity  payments
and,  subject  to some  restrictions, amounts  held as  annuity reserves  may be
transferred among  the  variable annuity  sub-accounts  and the  Funds.  Annuity
reserves  may be  transferred only  from a variable  annuity to  a fixed annuity
during the annuity period.

WHAT CHARGES ARE ASSOCIATED WITH THE CONTRACTS?
We deduct from the net  asset value of the  Variable Annuity Account an  amount,
computed  daily, equal to an annual rate of 1.25% for mortality and expense risk
guarantees. This  total  represents a  charge  of  .80% for  our  assumption  of
mortality  risks and .45%  for our assumption  of expense risks.  We reserve the
right to increase the  charge for the  assumption of expense  risks to not  more
than .60%. If this charge is increased to this maximum amount, then the total of
the mortality risk and expense risk charge would be 1.40% on an annual rate.
   
  In  addition, Advantus Capital  Management, Inc., ("Advantus  Capital") one of
our subsidiaries, acts as  the investment adviser to  the Advantus Series  Fund,
Inc.  and deducts from the net  asset value of each Portfolio  of the Fund a fee
for its services which are provided under an investment advisory agreement.  The
investment  advisory agreements with Advantus Capital provide that the fee shall
be computed at the  annual rate which may  not exceed .4% of  the Index 500  and
Index  400 Mid-Cap  Portfolios, .75% of  the Capital  Appreciation, Value Stock,
Small Company Value, Small  Company and the  Real Estate Securities  Portfolios,
1.0%  of the International Stock Portfolio .6% of the Global Bond Portfolio, .7%
of the Macro-Cap Value Portfolio, 1.1%  of the Micro-Cap Growth Portfolio,  .25%
for  each Maturing Government  Bond Portfolio and  .5% of each  of the remaining
Portfolio's average daily net assets.
    
   
  The Funds are subject to certain expenses that may be incurred with respect to
their operations and those expenses are allocated among the Portfolios. For more
information, see  the prospectuses  of each  Fund, which  are attached  to  this
Prospectus.  The Templeton Developing  Markets Fund pays  its investment adviser
management fees at  an annual  rate of  1.25% of  the Fund's  average daily  net
assets and pays other operating expenses which will vary every year but, for the
most  recent  fiscal  year, were  0.33%  of  its average  daily  net  assets. In
addition, Class 2 of the Templeton Developing Markets Fund has a rule 12b-1 plan
and may  pay  up  to  0.25%  annually  of  the  average  daily  net  assets  for
distribution. For more information, see the Fund's prospectus.
    
  In  addition, a deferred sales charge may apply. Deductions for any applicable
premium taxes may also be  made (currently such taxes  range from 0.0% to  3.5%)
depending upon applicable law.
  For  more information on  charges, see the heading  "Contract Charges" in this
Prospectus. The deferred sales charge is discussed below.
 
WHAT IS THE DEFERRED SALES CHARGE?
We deduct a deferred sales charge  on contract withdrawals, surrenders and  some
annuity  elections during the first ten  contract years for expenses relating to
the sale of the contracts. The amount  of any deferred sales charge is  deducted
from the accumulation value.
  Under  the flexible payment variable annuity  contract, the amount of deferred
sales charge, as a percentage of the amount surrendered, withdrawn or applied to
provide an annuity, decreases uniformly during the first ten contract years from
an initial charge of 9% to no charge after ten contract years.
  Under the single payment variable annuity contract, the amount of the deferred
sales charge, as a percentage of the amount surrendered, withdrawn or applied to
provide an annuity, decreases uniformly during the first ten contract years from
an initial charge of 6% to no charge after ten contract years.
  The deferred sales charge is not  applicable to some partial withdrawals  from
the  contracts. Also, there is  no deferred sales charge  on amounts paid in the
event of the death of the owner and the accumulation value is applied to provide
annuity payments under an option where  benefits are expected to continue for  a
period  of at  least five years.  For more  information on this  charge, see the
heading "Sales Charges" in this Prospectus.
 
CAN YOU MAKE PARTIAL WITHDRAWALS FROM THE CONTRACT?
Yes. You may make withdrawals of the accumulation value of your contract  before
an annuity begins. Partial withdrawals must be pursuant to your written request.
  Partial  withdrawals  are  generally  subject to  the  deferred  sales charge.
However, if withdrawals during the first calendar year are equal to or less than
10% of the  purchase payments made  during the  first calendar year  and, if  in
subsequent calendar years they are 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  to those  partial withdrawals.  The deferred  sales charge  described
above will apply to all withdrawal amounts which exceed 10% of that accumulation
value  in any  calendar year. In  addition, a  penalty tax may  be assessed upon
withdrawals from variable annuity contracts in
 
                                                                               7

certain circumstances.  For  more  information, see  the  heading  "Federal  Tax
Status" in this Prospectus.
 
DO YOU HAVE A RIGHT TO CANCEL THE CONTRACT?
   
Yes. You may cancel the contract any time within ten days of your receipt of the
contract  by  returning  it  to  us  or your  agent.  In  some  states,  such as
California, the free look period may  be extended. In California, the free  look
period  is extended to thirty days' time. These rights are subject to change and
may vary among the states.
    
 
IS THERE A GUARANTEED DEATH BENEFIT?
Yes. The single payment variable annuity contract has a guaranteed death benefit
if you die  before annuity  payments have started.  The death  benefit shall  be
equal  to the greater  of: (1) the  amount of the  accumulation value payable at
death; or (2) the  amount of the  total purchase payment paid  to us during  the
first year as consideration for this contract, less all contract withdrawals. As
a  matter of  company practice,  we use this  method except  that total purchase
payment will include  all contributions,  even those  made after  12 months,  to
determine the death benefit for all contracts offered by this Prospectus.
 
WHAT ANNUITY OPTIONS ARE AVAILABLE?
The  contracts  specify  several annuity  options.  Each annuity  option  may be
elected on either a variable  annuity or fixed annuity  or a combination of  the
two.  Other annuity options may  be available from us  on request. The specified
annuity options 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
and a period certain annuity.
 
WHAT IF THE OWNER DIES?
If you die  before payments begin,  we will  pay the accumulation  value of  the
contract  as a  death benefit  to the named  beneficiary. If  the annuitant dies
after annuity payments  have begun, 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 other than 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 date for annuity payments to begin.
 
WHAT VOTING RIGHTS DO YOU HAVE?
Contract  owners and  annuitants will  be able to  direct us  as to  how to vote
shares of  the  underlying  Fund  held for  their  contracts  where  shareholder
approval is required by law in the affairs of the Funds.

EXPENSE TABLE
The tables shown below are to assist a contract owner in understanding the costs
and  expenses  that  a  contract  will bear  directly  or  indirectly.  For more
information on contract costs and expenses, see the Prospectus heading "Contract
Charges" and the information immediately  following. The table does not  reflect
deductions for any applicable premium taxes which may be made from each purchase
payment  depending upon  the applicable  law. Surrender  amounts in  years shown
reflect the contract owner's ability to withdraw an amount equal to ten  percent
of  the accumulation value at the end  of the previous calendar year without the
imposition of the deferred  sales charge. The tables  show the expenses of  each
Fund after expense reimbursement.
  The  following  contract expense  information  is intended  to  illustrate the
expenses of the  MultiOption Annuity  variable annuity  contracts. All  expenses
shown are rounded to the nearest dollar. The information contained in the tables

(1) Minnesota Mutual  voluntarily  absorbed  certain expenses  of  the  Maturing
    Government  Bond 1998,  Maturing Government  Bond 2002,  Maturing Government
    Bond 2006, Maturing  Government Bond  2010, Small Company  Value, Index  400
    Mid-Cap,  Macro-Cap  Value and  Micro-Cap Growth  Portfolios for  the period
    ended December 31, 1997. If these portfolios had been charged for  expenses,
    the  ratio of  expenses to  average daily net  assets would  have been .74%,
    1.14%, 1.50%,  1.85%, 1.78%,  1.70%, 3.13%  and 2.03%,  respectively. It  is
    Minnesota Mutual's present intention to waive other fund expenses during the
    current  fiscal  year which  exceed, as  a percentage  of average  daily net
    assets, .15%. Minnesota Mutual also reserves the option to reduce the  level
    of other expenses which it will voluntarily absorb.
    
   
(2) Because the Portfolio will be available on May 1, 1998, the figure for other
    expenses  has  been  based  on  estimated  expenses  for  the  current year.
    Minnesota Mutual has voluntarily  agreed to absorb  or waive other  expenses
    which  exceed, as a percentage  of daily net assets,  .15%. If the Portfolio
    was to be  charged for these  expenses, it  is estimated that  the ratio  of
    total  expenses to average daily net assets would be 1.78%. Minnesota Mutual
    also reserves the option to reduce the level of other expenses which it will
    voluntarily absorb.
    
   
(3) Developing Markets Fund Class 2 has a distribution plan or "Rule 12b-1 Plan"
    which is described in the Fund's prospectus. The Rule 12b-1 Plan allows  for
    an  annual fee equal to  .25% of average daily  net assets of the Developing
    Markets Fund Class 2.

PERFORMANCE DATA
 
From  time  to  time the  Variable  Annuity Account  may  publish advertisements
containing performance data  relating to its  sub-accounts. In the  case of  the
Money  Market Sub-Account,  the Variable Annuity  Account 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 a one-year period and for the period since the  sub-
account became available pursuant to the Variable Annuity Account's registration
statement,  and  may also  include cumulative  total  return quotations  for the
period since  the sub-account  became available  pursuant to  such  registration
statement.  The Money Market sub-account may  also quote such average annual and
cumulative total  return  figures.  Performance figures  used  by  the  Variable
Annuity  Account 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 the Variable
Annuity Account will reflect  only charges made against  the net asset value  of
the  Variable Annuity Account pursuant to the  terms of the contracts offered by
this Prospectus.  The  various  performance figures  used  in  Variable  Annuity
Account  advertisements relating to  the contracts described  in this Prospectus
are summarized below. More detailed information on the computations is set forth
in the Statement of Additional Information.
 
MONEY MARKET  SUB-ACCOUNT  YIELD.      Yield  quotations  for the  Money  Market
Sub-Account  are  based  on  the  income  generated  by  an  investment  in  the
sub-account over  a  specified  period,  usually seven  days.  The  figures  are
"annualized,"  that is, the amount of  income generated by the investment during
the period is assumed to  be generated over a 52-week  period and is shown as  a
percentage   of  the  investment.  Effective  yield  quotations  are  calculated
similarly, but when annualized  the income earned by  an investment in the  sub-
account is assumed to be reinvested. Effective yield quotations will be slightly
higher  than yield quotations because of  the compounding effect of this assumed
reinvestment. Yield and effective yield  figures quoted by the Sub-Account  will
not reflect the deduction of any applicable deferred sales charges.
 
TOTAL  RETURN FIGURES.    Cumulative total return figures may also be quoted for
all Sub-Accounts.  Cumulative total  return is  based on  a hypothetical  $1,000
investment  in the Sub-Account at the beginning of the advertised period, and is
equal to  the percentage  change between  the  $1,000 net  asset value  of  that
investment  at  the beginning  of the  period and  the net  asset value  of that
investment at the end of the  period. Cumulative total return figures quoted  by
the  Sub-Account will not reflect the deduction of any applicable deferred sales
charges.
  Prior to  May 3,  1993, several  of the  Advantus Sub-Accounts  were known  by
different  names. The  Growth Sub-Account was  the Stock  Sub-Account, the Asset
Allocation Sub-Account was  the Managed Sub-Account,  the Index 500  Sub-Account
was  the  Index Sub-Account  and the  Capital  Appreciation Sub-Account  was the
Aggressive Growth Sub-Account.
   
  Prior to May 1, 1998, the Global Bond Portfolio was known as the International
Bond Portfolio.
    
  All cumulative  total  return  figures  published  for  Sub-Accounts  will  be
accompanied  by  average  annual total  return  figures for  a  one-year period,
five-year period  and for  the  period since  the Sub-Account  became  available
pursuant  to  the  Variable Annuity  Account's  registration  statement. Average
annual total  return figures  will show  for the  specified period  the  average
annual  rate of return required for an initial investment of $1,000 to equal the
surrender value of that investment at the end of the period. The surrender value
will reflect  the deduction  of  the deferred  sales  charge applicable  to  the
contract  and to the length of the  period advertised. Such average annual total
return figures may also be accompanied  by average annual total return  figures,
for  the  same or  other  periods, which  do not  reflect  the deduction  of any
applicable deferred sales charges.
 
PREDICTABILITY OF  RETURN.        For  each  of  the  Maturing  Government  Bond
Sub-Accounts,  Minnesota Mutual will calculate  an anticipated growth rate (AGR)
on each  day that  the underlying  Portfolio of  the Fund  is valued.  Minnesota
Mutual  may also calculate  an anticipated value  at maturity (AVM)  on any such
day. Daily  calculations for  each are  necessary because  (i) the  AGR and  AVM
calculations  assume,  among  other  things,  an  expense  ratio  and  portfolio
composition that remains unchanged for the life of each such Sub-Account to  the
target  date at maturity, and (ii) such calculations are therefore meaningful as
a measure of predictable  return with respect to  particular units only if  such
units are held to
 
                                                                              15
<PAGE>
the  applicable target maturity date and only with respect to units purchased on
the date of such calculations (the AGR and AVM applicable to units purchased  on
any  other  date may  be materially  different). Those  assumptions can  only be
hypothetical given  that owners  of contracts  have the  option to  purchase  or
redeem  units on  any business day  through contract activity,  and will receive
dividend and capital gain distributions through the receipt of additional shares
to their unit values. A number of factors in addition to contract owner activity
can cause a Maturing  Government Bond Sub-Account's AGR  and AVM to change  from
day  to day. These include the adviser's efforts to improve total return through
market opportunities, transaction costs, interest rate changes and other  events
that affect the market value of the investments held in each Maturing Government
Bond  Portfolio in the  Fund. Despite these  factors, it is  anticipated that if
specific units  of  a Maturing  Government  Bond  Sub-Account are  held  to  the
applicable  target maturity date, then the AGR  and AVM applicable to such units
(i.e., calculated as of the date of  purchase of such units) will vary from  the
actual return experienced by such units within a narrow range.

55101-2098,  telephone: (612) 665-3500; after September 1, 1998, (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 ANNUITY ACCOUNT
A separate  account called  the Minnesota  Mutual Variable  Annuity Account  was
established  on September 10, 1984, by our  Board of Trustees in accordance with
certain provisions  of the  Minnesota  insurance law.  The separate  account  is
registered  as  a  "unit  investment trust"  with  the  Securities  and Exchange
Commission under the Investment Company Act of 1940, but such registration  does
not   signify  that  the  Securities  and  Exchange  Commission  supervises  the
management, or the  investment practices  or policies, of  the Variable  Annuity
Account. The separate account meets the definition of a "separate account" under
the federal securities laws.
  The  Minnesota law  under which the  Variable Annuity  Account was established
provides that the assets of the Variable Annuity Account shall not be chargeable
with liabilities arising  out of any  other business which  we may conduct,  but
shall  be held and  applied exclusively to  the benefit of  the holders of those
variable annuity contracts for which  the separate account was established.  The
investment  performance of the Variable  Annuity Account is entirely independent
of both  the investment  performance of  our General  Account and  of any  other
separate  account  which we  may have  established or  may later  establish. All
obligations under the contracts are  general corporate obligations of  Minnesota
Mutual.
  The  Variable Annuity Account  currently has twenty-one  sub-accounts to which
contract owners  may allocate  purchase payments.  Each sub-account  invests  in
shares of a corresponding Portfolio of the Funds. Additional sub-accounts may be
added at our discretion.
 
C.  ADVANTUS SERIES FUND, INC.
   
The  Variable Annuity  Account currently invests  in Advantus  Series Fund, Inc.
(the "Series  Fund"), a  mutual fund  of the  series type  which is  advised  by
Advantus  Capital Management, Inc. Prior to May  1, 1997, the name of the Series
Fund was  "MIMLIC Series  Fund, Inc."  The Series  Fund is  registered with  the
Securities  and Exchange Commission as a diversified (except for the Global Bond
Portfolio), open-end management investment  company, but such registration  does
not  signify that  the Commission supervises  the management,  or the investment
practices or policies, of  the Series Fund. The  Series Fund issues its  shares,
continually  and without  sales charge,  only to  us and  our separate accounts,
which currently  include the  Variable  Annuity Account,  Variable Fund  D,  the
Variable  Life  Account, the  Group Variable  Annuity  Account and  the Variable
Universal Life  Account. The  Series Fund  may also  be used  as the  underlying
investment medium for separate accounts of the Northstar Life Insurance Company,
a  wholly-owned life insurance subsidiary of Minnesota Mutual which is domiciled
in New York. Shares are sold and redeemed  at net asset value. In the case of  a
newly  issued contract, purchases of shares of the Portfolios of the Series Fund
in connection
    
 
16
<PAGE>
with the first  purchase payment  will be based  on the  values next  determined
after issuance of the contract by us. Redemptions of shares of the Portfolios of
the  Series Fund are made  at the net asset  value next determined following the
day we receive a  request for transfer, partial  withdrawal or surrender at  our
home  office. In the case  of outstanding contracts, purchases  of shares of the
Portfolio of the Series Fund  for the Variable Annuity  Account are made at  the
net  asset value of such shares next  determined after receipt by us of contract
purchase payments.
   
  The Series  Fund's investment  adviser is  Advantus Capital  Management,  Inc.
("Advantus  Capital"). Advantus Capital  is a wholly-owned  subsidiary of MIMLIC
Asset Management  Company ("MIMLIC  Management")  which prior  to May  1,  1997,
served  as  investment  adviser  to  the Series  Fund.  MIMLIC  Management  is a
wholly-owned subsidiary of Minnesota Mutual. It acts as an investment adviser to
the Fund pursuant to an advisory agreement.
    
   
  Advantus Capital acts as investment adviser  for the Fund and its  Portfolios.
Winslow Capital Management, Inc., a Minnesota corporation with principal offices
at  4720 IDS  Tower, 80 South  Eighth Street, Minneapolis,  Minnesota 55402, has
been retained under an investment  sub-advisory agreement with Advantus  Capital
Management,  Inc.  to provide  investment advice  and,  in general,  conduct the
management  and  investment  program  of  the  Capital  Appreciation  Portfolio.
Similarly,  Templeton  Investment  Counsel,  Inc.,  a  Florida  corporation with

International Stock Portfolio  of the  Fund. J.P.  Morgan Investment  Management
Inc.,  a Delaware corporation with principal offices  in New York, New York, has
been retained under an investment  sub-advisory agreement to provide  investment
advice  for the Macro-Cap Value Portfolio of the Fund. Wall Street Associates, a

Management, Inc., a Delaware corporation with principal offices in New York, New
York, has been retained  under an investment  sub-advisory agreement to  provide
investment advice for the Global Bond Portfolio of the Fund.
    
  A  prospectus for  the Fund  is attached to  this Prospectus.  A person should
carefully read the Fund's prospectus before investing in the contracts.
 
D.  TEMPLETON VARIABLE PRODUCTS SERIES FUND
In addition to the investments in the Fund, the Variable Annuity Account invests
in the  Templeton  Developing  Markets  Fund, a  diversified  portfolio  of  the
Templeton Variable Products Series Fund, a mutual fund of the series type.
  The  investment objectives  and certain  policies of  the Templeton Developing
Markets Fund available under the Contract are as follows:
 
    The Templeton Developing Markets Fund seeks long-term capital  appreciation.
    It  pursues this  objective by investing  primarily in  equity securities of
    issuers  in  countries  having   developing  markets.  Countries   generally
    considered  to have developing markets are all countries that are considered
    to be  developing  or  emerging  countries by  the  International  Bank  for
    Reconstruction and Development (more commonly referred to as the World Bank)
    or  the International  Finance Corporation,  as well  as countries  that are
    classified by the United Nations or otherwise regarded by their  authorities
    as developing.
  Class  2 of the  Templeton Developing Markets  Fund pays 0.25%  of the average
daily net assets annually under a distribution plan adopted under Rule 12b-1  of
the  Investment  Company Act  of  1940. Amounts  paid  under the  12b-1  plan to
Minnesota Mutual may be used for certain contract owner services or distribution
activities.
  The investment adviser of Templeton Developing Markets Fund is Templeton Asset
Management Ltd.,  a  Singapore  corporation.  It  is  an  indirect  wholly-owned
subsidiary  of Franklin Resources, Inc.  ("Franklin"). Through its subsidiaries,
Franklin  is  engaged  in  the   financial  services  industry.  The   Templeton
organization  has been investing  globally since 1940  and, with its affiliates,
provides investment management and advisory services to a worldwide client base.
The investment adviser and its affiliates have offices worldwide.
 
E.  ADDITIONS, DELETIONS OR SUBSTITUTIONS
We retain the right, subject to  any applicable law, to make substitutions  with
respect   to   the   investments   of   the   sub-accounts   of   the   Variable
 
                                                                              17
<PAGE>
Annuity Account. If investment in a fund  should no longer be possible or if  we
determine  it  becomes  inappropriate  for  contracts  of  this  class,  we  may
substitute another fund for a sub-account.  Substitution may be with respect  to
existing  accumulation  values,  future  purchase  payments  and  future annuity
payments.
  We may also establish additional sub-accounts in the Variable Annuity  Account
and  we reserve  the right  to add,  combine or  remove any  sub-accounts of the
Variable Annuity Account. Each additional sub-account will purchase shares in  a
new  portfolio or mutual fund. Such sub-accounts may be established when, in our
sole discretion, marketing,  tax, investment  or other  conditions warrant  such
action.   Similar  considerations  will  be  used   by  us  should  there  be  a
determination to  eliminate one  or more  of the  sub-accounts of  the  Variable
Annuity Account. The addition of any investment option will be made available to
existing contract owners on such basis as may be determined by us.
  We  also reserve the right, when permitted by law, to de-register the Variable
Annuity Account  under  the Investment  Company  Act  of 1940,  to  restrict  or
eliminate  any voting rights of the contract owners, and to combine the Variable
Annuity Contract with one or more of our other separate accounts.
  Shares of  the  Portfolios  of the  Funds  are  also sold  to  other  separate
accounts, which are used to receive and invest premiums paid under variable life
policies.  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 Fund simultaneously. Although neither Minnesota Mutual nor  the
Funds  currently  foresees  any  such  disadvantages  either  to  variable  life
insurance policy owners or to variable annuity contract owners, the 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 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 laws, (2) changes in Federal income tax laws, (3)
changes  in the investment management  of any of the  Portfolios of the Fund, or
(4) differences in voting instructions between those given by policy owners  and
those given by contract owners.

CONTRACT CHARGES
 
A.  SALES CHARGES
No  sales charge  is deducted  from the  purchase payments  for these contracts.
However, when  a  contract's accumulation  value  is reduced  by  a  withdrawal,
surrender  or applied  to provide  an annuity,  a deferred  sales charge  may be
deducted for expenses relating to the sale of the contracts.
   
  No deferred sales charge is deducted from the accumulation value withdrawn if:
(a) the withdrawal occurs after  a contract has been in  force for at least  ten
contract  years, (b) withdrawals during the first  calendar year are equal to or
less than 10% of the purchase payments and, if in subsequent calendar years they
are equal to  or less  than 10%  of the  accumulation value  at the  end of  the
previous  calendar year,  (c) the  withdrawal is  on account  of the annuitant's
death, or (d) the  withdrawal is for the  purpose of providing annuity  payments
under an option where payments are expected to continue for at least five years.
If  withdrawals in  a calendar  year exceed  10% of  those purchase  payments or
accumulation value,  the  sales charge  applies  to  the amount  of  the  excess
withdrawal.  In addition, we  will waive the  sales charge on  that portion of a
contract's accumulation value which is applied to the purchase of an  Adjustable
Income  Annuity, which is an immediate  variable annuity contract, issued by us.
We will also waive the  sales charge on amounts  withdrawn because of an  excess
contribution to a tax-qualified contract.
    
  The  sales charge  is deducted  from the  remaining accumulation  value of the
contract except  in  the  case of  a  surrender,  where it  reduces  the  amount
distributed.  We will deduct the sales  charge proportionally from the fixed and
variable accumulation value of the contract.
  The amount of  the deferred  sales charge, expressed  as a  percentage of  the
accumulation  value withdrawn, is shown in  the following table. Percentages are
shown as of  the contract date  and the end  of each of  the first ten  contract
years.  The percentages  decrease uniformly each  month for 120  months from the
contract date. In no event will the sum of the deferred sales charges exceed  9%
of the purchase payments made under a contract.

Deduction  for any applicable state premium taxes may be made from each purchase
payment or at the commencement of annuity payments. (Currently, such taxes range
from 0.5% to 3.5%, depending on  the applicable law.) Any amount withdrawn  from
the  contract may be reduced  by any premium taxes  not previously deducted from
purchase payments.
   
  As a percentage of purchase payments  paid to the contracts, Ascend  Financial
Services,  Inc. ("Ascend Financial"),  the principal underwriter,  may pay up to
4.5% of the amount of those purchase payments to broker-dealers responsible  for
the  sales of the  contracts. In addition, Ascend  Financial or Minnesota Mutual
will pay, based  uniformly on  the sale of  variable annuity  contracts by  such
broker-dealers,   credits  which   allow  registered   representatives  who  are
responsible for sales of  variable annuity contracts  to attend conventions  and
other  meetings sponsored by Minnesota Mutual  or its affiliates for the purpose
of promoting the  sale of the  insurance and/or investment  products offered  by
Minnesota  Mutual  and its  affiliates. Such  credits  may cover  the registered
representatives' transportation, hotel accommodations, meals, registration  fees
and  the like.  Minnesota Mutual may  also pay  those registered representatives
amounts based upon their  production and the persistency  of life insurance  and
annuity business placed with Minnesota Mutual.
    
 
B.  MORTALITY AND EXPENSE RISK CHARGES
We  assume the mortality risk under the  contracts by our obligation to continue
to make monthly annuity payments, determined in accordance with the annuity rate
tables and  other  provisions contained  in  the contracts,  to  each  annuitant
regardless  of how long that annuitant lives  or all annuitants as a group live.
This assures an  annuitant that  neither the  annuitant's own  longevity nor  an
improvement  in life  expectancy generally  will have  an adverse  effect on the
monthly annuity payments received under the contract.
  We assume an expense risk by assuming the risk that deductions provided for in
the contracts for  the sales  and administrative  expenses will  be adequate  to
cover the expenses incurred.
  For  assuming these  risks, we  currently make  a deduction  from the Variable
Annuity Account at the annual rate of  .80% for the mortality risk and .45%  for
the expense risk. We reserve the right to increase the charge for the assumption
of  expense risks  to not more  than .60%. If  this charge is  increased to this
maximum amount, then  the total of  the mortality risk  and expense risk  charge
would be 1.40% on an annual basis.
  For  a discussion of how  these charges are applied  in the calculation of the
accumulation unit value, please see the discussion entitled "Purchase  Payments,
Value of the Contract and Transfers" on page 26.
  If  these deductions prove to be insufficient  to cover the actual cost of the
expense and mortality  risks assumed by  us, then we  will absorb the  resulting
losses  and make sufficient  transfers to the Variable  Annuity Account from our
general account, where appropriate. Conversely, if these deductions prove to  be
more  than sufficient after the establishment of any contingency reserves deemed
prudent or required by law, any excess will be profit (or "surplus") to us. Some
or all of such profit may be used to cover any distribution costs not  recovered
through the deferred sales charge.
 
- ------------------------------------------------------------------------
EXCHANGE OFFER
 
Persons  owning  or having  an interest  in  certain of  our fixed  and variable
annuities may exchange those  interests for the  contracts described herein  and
transfer current accumulation values into the contracts.
  The  persons eligible  for the  exchange include:  owners of  individual fixed
annuities issued by Minnesota  Mutual and The  Ministers Life Insurance  Company
except  for those contracts  known as SPDA 3  and SecureOption III; participants
under Minnesota Mutual  group annuities  offering fixed  benefits in  situations
other  than  where the  contract is  issued  in connection  with a  stock bonus,
pension or profit sharing  plan which meets  the requirements for  qualification
under  section 401 of  the Internal Revenue Code  and variable annuity contracts
 
                                                                              19
<PAGE>
issued by Minnesota  Mutual Variable  Fund D  with a  contingent deferred  sales
charge.
   
  Persons  who own combination  fixed and variable  annuity contracts, where any
general account  assets are  beyond  the period  where  a withdrawal  charge  is
applicable,  may  also  be  eligible  for  such  contract  exchanges.  For these
contracts, allocations as between  fixed and variable  accumulations may not  be
altered  at the time of the exchange.  In addition, for contracts with interests
in Minnesota Mutual Variable Fund D, other than those with a contingent deferred
sales load,  the  contract or  participation  must be  of  at least  ten  year's
duration.  No charge is made  to this transfer. For  contracts described in this
Prospectus, where  the contract  type is  to be  exchanged, for  example from  a
single  payment contract to a  flexible payment contract, we  will allow such an
exchange only during the  original contract's first contract  year and if  there
have  been no  transfers or withdrawals.  Also, for contracts  described in this
Prospectus, we will allow exchanges  of contracts which are essentially  changes
of  qualified plan  types as, for  example, when  a person wishes  to convert an
existing IRA into a Roth IRA. In some circumstances where multiple contracts are
being exchanged for the  convenience of the contractholder,  a charge of $50  to
cover administrative expense may be imposed.
    
  For  exchanges  from annuities  where  a sales  charge  is deducted  from each
purchase payment  received from  the owner,  accumulation values  credited to  a
contract  at the time of transfer will not be subject to a deferred sales charge
at any time. However, purchase payments subsequently made to the contract may be
subject to  a  deferred  sales  charge  if  such  amounts  are  then  withdrawn,
surrendered  or applied to provide an annuity. The deferred sales charge will be
applied so that the contract year of  the contract will be determined as of  the
contract date of the annuity from which the accumulation value was transferred.
  For  exchanges from  annuities where  a deferred sales  charge may  be made on
withdrawals, surrenders or when  amounts are applied to  provide an annuity,  no
deferred  sales charge will be made at the time of transfer. However, a deferred
sales charge may be deducted from the accumulation value of the contract on such
a basis so that the contract year of  the contract will be determined as of  the
contract  date of the annuity from  which the accumulation value was transferred
or, if transfer is of  participation in a group annuity,  from the first day  of
the  month in which contributions were  first received from the individual under
the group annuity contract on behalf of that individual.
  In considering an exchange, you should  review the provisions of the  contract
you  now own and  the contracts described  in the Prospectus.  To effect such an
exchange,  your  completed  application,  Annuity  Exchange  Authorization   and
existing annuity contracts should be returned to us.
   
  Inquiries  regarding the contracts mentioned  above or the contracts described
in this Prospectus may be directed to  us at: Minnesota Mutual Life Center,  400
Robert  Street North, St. Paul, Minnesota 55101-2098;  or by calling us at (612)
665-3500; after September 1, 1998, (651) 665-3500.
    
 
- ------------------------------------------------------------------------
VOTING RIGHTS
 
The Fund shares held in the Variable Annuity Account will be voted by us at  the
regular and special meetings of the Funds. Shares attributable to contracts will
be  voted by  us in accordance  with instructions received  from contract owners
with voting interests in  each sub-account of the  Variable Annuity Account.  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
Portfolio  and shares  not attributable to  contracts in the  same proportion as
shares of the  Portfolio held by  such sub-account for  which instructions  have
been  received. The number of votes which are available to a contract owner will
be calculated separately for each  sub-account of the Variable Annuity  Account.
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 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
 
20
<PAGE>
contract  allocated to each sub-account by the  net asset value per share of the
underlying 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  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.
 
- ------------------------------------------------------------------------------
DESCRIPTION OF THE CONTRACTS
 
A.  GENERAL PROVISIONS
 
1.  TYPES OF CONTRACTS OFFERED
 
    (a) Single Payment Variable Annuity Contract
 
    This type  of  contract  may  be  used  in  connection  with  a  pension  or
    profit-sharing  plan under which plan  contributions have been accumulating.
    It may be used in  connection with a plan  which has previously been  funded
    with  insurance or  annuity contracts. It  may be used  under state deferred
    compensation plans or individual retirement annuity programs. It may also be
    purchased by individuals not as a  part of any qualified plan. 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.
 
    (b) Flexible Payment Variable Annuity Contract
 
    This type of contract  may be used  in connection with  all types of  plans,
    state deferred compensation plans or individual retirement annuities adopted
    by  or on behalf of individuals. It may also be purchased by individuals not
    as a part of  any plan. 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  you, the contract owner  named in the application.
The owner of the contract may be the annuitant or someone else.
 
3.  MODIFICATION OF THE CONTRACTS
A contract may be modified at any time by written agreement between you and  us.
However,  no such modification will adversely  affect the rights of an annuitant
under the contract  unless the  modification is  made to  comply with  a law  or
government  regulation.  You  will  have  the  right  to  accept  or  reject the
modification. This right  of acceptance  or rejection is  limited for  contracts
used as individual retirement annuities.
 
4.  ASSIGNMENT
If  the contract is sold in  connection with a tax-qualified program, (including
employer sponsored employee pension  benefit plans, tax-sheltered annuities  and
individual  retirement annuities,) your  or the annuitant's  interest 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.
  If  the contract is not issued in connection with a tax-qualified program, the
interest of any person in  the contract may be  assigned during the lifetime  of
the  annuitant. We will  not be bound  by any assignment  until we have recorded
written notice of it at our home office. We are not responsible for the validity
of any assignment. An assignment will not apply to any payment or action made by
us before it was recorded. Any proceeds which become payable to an assignee will
be payable in a  single sum. Any claim  made by an assignee  will be subject  to
proof of the assignee's interest and the extent of the assignment.
 
5.  LIMITATIONS ON PURCHASE PAYMENTS
For  the single  payment variable annuity  contract, the single  payment will be
deemed to include all  purchase payments made within  12 months of the  contract
date.  The amount of  an initial purchase  payment must be  at least $5,000. The
amount of any subsequent payment  during that 12 month  period must be at  least
$1,000.  Some states, for example,  New Jersey, will limit  these contracts to a
single purchase payment and contracts issued there are so limited.
 
                                                                              21

  You choose when to  make purchase payments under  a flexible payment  variable
annuity  contract. There is no  minimum purchase payment amount  and there is no
minimum amount  which must  be  allocated to  any  sub-account of  the  Variable
Annuity Account or to the General Account.
  Total  purchase  payments under  either  contract may  not  exceed $1,000,000,
except with our consent.
  We may cancel a flexible payment  contract, in our discretion, if no  purchase
payments  are made for a period of two  or more full contract years and both (a)
the total purchase payments made,  less any withdrawals and associated  charges,
and  (b) the accumulation value of the entire contract, are less than $2,000. If
such a cancellation takes place, we will pay you the accumulation value of  your
contract  and we  will notify you,  in advance,  of our intent  to exercise this
right in our annual report which advises contract owners of the status of  their
contracts.  We will act  to cancel the  contract ninety days  after the contract
anniversary unless an additional purchase payment is received before the end  of
that  ninety  day period.  Contracts  issued in  some  states, for  example, New
Jersey, do not  permit such  a cancellation and  contracts issued  there do  not
contain this provision.
  There  may be  limits on  the maximum  contributions to  retirement plans that
qualify for special tax treatment.
 
6.  DEFERMENT OF PAYMENT
Whenever any payment under  a contract is  to be made in  a single sum,  payment
will  be made within seven days after the date such payment is called for by the
terms of the contract, except as payment may be subject for postponement for:
 
    (a) any period during which the New York Stock Exchange is closed other than
        customary weekend and holiday closings,  or during which trading on  the
        New  York Stock Exchange is restricted,  as determined by the Securities
        and Exchange Commission;
 
    (b) any period  during  which  an  emergency exists  as  determined  by  the
        Commission  as  a result  of  which it  is  not reasonably  practical to
        dispose of securities in  the Fund or to  fairly determine the value  of
        the assets of the Fund; or
 
    (c) such  other  periods  as the  Commission  may  by order  permit  for the
        protection of the contract owners.
 
7.  PARTICIPATION IN DIVISIBLE SURPLUS
The contracts  participate in  our divisible  surplus, according  to the  annual
determination  of  our Board  of  Trustees as  to the  portion,  if any,  of our
divisible surplus which has accrued on the contracts.
  No assurance can be given as to the amount of divisible surplus, if any,  that
will be distributable under these contracts in the future. Such amount may arise
if  mortality and  expense experience is  more favorable than  assumed. When any
distribution of divisible surplus  is made, it may  take the form of  additional
payments to annuitants or the crediting of additional accumulation units.
 
B.  ANNUITY PAYMENTS AND OPTIONS
 
1.  ANNUITY PAYMENTS
Variable annuity payments are determined on the basis of (a) the mortality table
specified in the contract, which reflects the age of the annuitant, (b) the type
of  annuity payment option  selected, and (c) the  investment performance of the
Fund Portfolios  selected by  the contract  owner. 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,  however,  reflect  investment  gains  and  losses  and
investment income of the Funds, and thus the annuity payments will vary with the
investment experience of the assets of the Portfolio of the Fund selected by the
contract owner.
 
2.  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  annuity basis, or a  combination of the two. Other
annuity options may be available from us on request.
  While the contracts require that notice of election to begin annuity  payments
must  be received by us at least 30 days prior to the annuity commencement date,
we are currently waiving  that requirement for  such variable annuity  elections
received at least three
 
22
<PAGE>
valuation  days prior to the 15th of the  month. We reserve the right to enforce
the 30 day notice requirement at our option at any time in the future.
  Each contract permits  an annuity payment  to begin  on the first  day of  any
month.  Under the  contracts payment  must begin  before the  later of  the 85th
birthday of  the  annuitant, or  five  years after  the  date of  issue  of  the
contracts.  A variable annuity will be provided  and the annuity option shall be
Option 2A, a life annuity with a period of 120 months. 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 surrender value  of the contract which would otherwise have
been applied to provide annuity payments.
  Once annuity payments have commenced, you cannot surrender an annuity  benefit
and receive a single sum settlement in lieu thereof.
  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.
 
3.  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 monthly payment 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 died prior to the due date of the second annuity payment,
two if he died before the due date of the third annuity payment, etc.
 
OPTION 2--LIFE ANNUITY WITH A PERIOD CERTAIN OF 120 MONTHS (OPTION 2A), 180
MONTHS (OPTION 2B), OR 240 MONTHS (OPTION 2C)
This is an annuity  payable monthly during the  lifetime of the annuitant,  with
the  guarantee that if the annuitant dies before payments have been made for the
period certain elected,  payments will  continue to the  beneficiary during  the
remainder of the period certain. 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 and using the  same interest rate which served  as a basis for the
annuity 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. If this
option is elected, the contract and payments shall then be the joint property of
the annuitant and  the designated joint  annuitant. It would  be possible  under
this option for both annuitants to receive only one annuity payment if they both
died  prior to  the due  date of the  second annuity  payment, two  if they died
before the due date of the third annuity payment, etc.
 
OPTION 4--PERIOD CERTAIN ANNUITY
This is an annuity payable monthly for a  period certain of from 5 to 20  years,
as  elected. If the annuitant dies before payments have been made for the period
certain elected, payments will continue during the remainder of the fixed period
to the beneficiary. Contracts issued prior to May of 1993, or such later date as
we receive regulatory approval to issue these  new contracts in a state and  are
administratively  able to  do so,  may allow  the election  of a  period certain
option of less than five years. In the event of the death of the annuitant,  the
beneficiary  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.
 
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 available  value of the  contract when an  annuity
begins.  In addition, a number  of states do impose a  premium tax on the amount
used to purchase  an annuity benefit,  depending on the  type of plan  involved.
Where applicable, these taxes 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
 
                                                                              23
<PAGE>
deductions from purchase payments as they are received.
  The amount of the first monthly  payment depends on the optional annuity  form
elected  and the adjusted  age of the  annuitant. A formula  for determining the
adjusted age is contained in the contract.
  The contracts contain tables indicating the  dollar amount of the first  fixed
monthly  payment  under each  optional  annuity form  for  each $1,000  of value
applied. The  tables are  determined  from the  Progressive Annuity  Table  with
interest  at the rate of 3%  per annum, assuming births in  the year 1900 and an
age setback of six years.  Also, for contracts issued  after 1993 or such  later
date  as we may be  able to issue this contract  in a jurisdiction, the contract
contains a provision that applies a contract fee of $200 when a fixed annuity is
elected. 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.
  The dollar amount of the first monthly variable annuity payment is  determined
by  applying  the available  value  (after deduction  of  any premium  taxes not
previously deducted) to  a rate  per $1,000 which  is based  on the  Progressive
Annuity  Table with interest at  the rate of 4.5%  per annum, assuming births in
the year 1900  and with an  age setback of  six years. The  amount of the  first
payment depends upon the annuity payment option selected and the adjusted age of
the  annuity  and  any  joint  annuitant. A  number  of  annuity  units  is then
determined by  dividing this  dollar amount  by the  then current  annuity  unit
value.  Thereafter, the  number of  annuity units  remains unchanged  during the
period of annuity payments. This determination is made separately for each  sub-
account  of the separate account. The number  of annuity units is based upon the
available value  in each  sub-account as  of the  date annuity  payments are  to
begin.
  The  dollar amount determined for each sub-account will then be aggregated for
purposes of making payment.
  The 4.5% interest  rate assumed  in the variable  annuity determination  would
produce  level annuity payments if the  net investment rate remained constant at
4.5% per year. Subsequent  payments will decrease, remain  the same or  increase
depending upon whether the actual net investment rate is less than, equal to, or
greater  than 4.5%. A higher interest rate means a higher initial payment, but a
more slowly rising (or  more rapidly falling) series  of subsequent payments.  A
lower  assumption has the opposite effect. For  contracts issued prior to May of
1993, or such later date as when  we receive regulatory approval to issue  these
new  contracts in a state and are administratively able to do so, which utilized
such a lower rate, the payments will  differ from these contracts in the  manner
described.
  Annuity payments are always made as of the first day of a month. The contracts
require that notice of election to begin annuity payments must be received by us
at  least thirty days prior to the annuity commencement date. However, Minnesota
Mutual currently waives  this requirement,  and at  the same  time reserves  the
right to enforce the thirty day notice at its option in the future.
  Money  will be transferred to the General  Account for the purpose of electing
fixed annuity payments, or to the appropriate variable sub-accounts for variable
annuity payments, on the valuation date coincident with the first valuation date
following the  fourteenth day  of the  month  preceding the  date on  which  the
annuity is to begin.
  If  a request for a fixed annuity is received between the first valuation date
following the fourteenth day of the month and the second to last valuation  date
of  the month prior  to commencement, the  transfer will occur  on the valuation
date coincident  with  or  next following  the  date  on which  the  request  is
received.  If a fixed  annuity request is  received after the  third to the last
valuation day  of the  month prior  to commencement,  it will  be treated  as  a
request  received the following month, and the commencement date will be changed
to the first of the month following the requested commencement date. The account
value used to determine fixed annuity payments will be the value as of the  last
valuation date of the month preceding the date the fixed annuity is to begin.
  If  a  variable annuity  request is  received after  the third  valuation date
preceding the first  valuation date following  the fourteenth day  of the  month
prior  to the commencement  date, it will  be treated as  a request received the
following month, and the commencement date will  be changed to the first of  the
month  following  the requested  commencement date.  The  account value  used to
determine the initial variable annuity payment will be the value as of the first
valuation date following the fourteenth day  of the month prior to the  variable
annuity begin date.
 
24
<PAGE>
5.  AMOUNT OF SECOND AND SUBSEQUENT MONTHLY ANNUITY PAYMENTS
The  dollar amount of the second and later variable annuity payments is equal to
the number of annuity  units determined for each  sub-account times the  annuity
unit  value for that sub-account as of the  due date of the payment. This amount
may increase or decrease from month to month.
 
6.  VALUE OF THE ANNUITY UNIT
The value of an annuity unit for  a sub-account is determined monthly as of  the
first  day  of each  month by  multiplying the  value  on the  first day  of the
preceding month by the product of (a) .996338, and (b) the ratio of the value of
the accumulation unit for that sub-account 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  (.996338  is a  factor  to neutralize  the  assumed net  investment rate,
discussed in Section 3  above, of 4.5%  per annum built  into the first  payment
calculation  which is not  applicable because the actual  net investment rate is
credited instead). The value of an annuity unit for a sub-account 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.
 
7.  TRANSFER OF ANNUITY RESERVES
Amounts held as annuity reserves may  be transferred among the variable  annuity
sub-accounts during the annuity period. Annuity reserves may also be transferred
from  a variable annuity to a fixed annuity during this time. The change must be
made by a written request. The annuitant and joint annuitant, if any, must  make
such an election.
  There  are restrictions to such a transfer. The transfer of an annuity reserve
amount from any  sub-account must  be at  least equal  to $5,000  or the  entire
amount  of  the  reserve remaining  in  that sub-account.  In  addition, annuity
payments must have been in effect for a period of 12 months before a change  may
be  made. Such  transfers can  be made  only once  every 12  months. The written
request for an  annuity transfer must  be received by  us more than  30 days  in
advance  of the due  date of the  annuity payment subject  to the transfer. Upon
request, we  will  make available  to  you annuity  reserve  amount  sub-account
information.
  A  transfer will be  made on the basis  of annuity unit  values. The number of
annuity units from  the sub-account  being transferred  will be  converted to  a
number  of annuity units in the new sub-account. The annuity payment option will
remain the  same and  cannot be  changed.  After this  conversion, a  number  of
annuity  units in the new sub-account will  be payable under the elected option.
The first payment after conversion will be  of the same amount as it would  have
been  without the  transfer. The  number of  annuity units  will be  set at that
number of units which are needed to pay that same amount on the transfer date.
  When we receive a  request for the transfer  of variable annuity reserves,  it
will  be effective for  future annuity payments. The  transfer will be effective
and funds actually  transferred in the  middle of  the month prior  to the  next
annuity  payment  affected  by your  request.  We  will use  the  same valuation
procedures to determine your  variable annuity payment  that we used  initially.
However,  if your  annuity is  based upon annuity  units in  a sub-account which
matures on  a date  other than  the  stated annuity  valuation date,  then  your
annuity  units  will  be  adjusted to  reflect  sub-account  performance  in the
maturing sub-account and the sub-account  to which reserves are transferred  for
the period between annuity valuation dates.
  Amounts  held as reserves to pay a variable annuity may also be transferred to
a fixed annuity during the annuity period. However, the restrictions which apply
to annuity sub-account  transfers will apply  in this case  as well. The  amount
transferred  will then be applied to provide a fixed annuity amount. This amount
will be based upon the adjusted age of the annuitant and any joint annuitant  at
the  time of  the transfer.  The annuity  payment option  will remain  the same.
Amounts paid as a fixed annuity may not be transferred to a variable annuity.
  When we receive a request to make such a transfer to a fixed annuity, it  will
be  effective for  future annuity payments.  The transfer will  be effective and
funds actually transferred in the middle of the month prior to the next  annuity
payment. We will use the same fixed annuity pricing at the time of transfer that
we use to determine an initial fixed annuity payment.
  Contracts with this transfer feature may not be available in all states.
 
C.  DEATH BENEFITS
The contracts provide that in the event of the death of the owner before annuity
payments  begin, the amount  payable at death will  be the contract accumulation
value  determined   as  of   the  valuation   date  coincident   with  or   next
 
                                                                              25
<PAGE>
following  the date  due proof of  death is received  by us at  our home office.
Death proceeds will be paid in a single sum to the beneficiary designated unless
an annuity option is elected.  Payment will be made  within seven days after  we
receive  due proof of death.  Except as noted below,  the entire interest in the
contract must be distributed within five years of the owner's death.
  The single payment variable annuity contract has a guaranteed death benefit if
you die before annuity payments have  started. The death benefit shall be  equal
to the greater of: (1) the amount of the accumulation value payable at death; or
(2) the amount of the total purchase payments paid to us during the first twelve
months  as consideration for this contract,  less all contract withdrawals. As a
matter of  company practice,  we  use this  method  except that  total  purchase
payments  will include all contributions, even those made after twelve months to
determine the death benefit for all contracts offered by this Prospectus.
  If the owner dies  on or before  the date on which  annuity payments begin  we
will pay the greater of the accumulated value or the guaranteed death benefit to
the designated beneficiary. If the designated beneficiary is a person other than
the  owner's spouse, that beneficiary may elect  an annuity option measured by a
period not  longer than  that  beneficiary's life  expectancy  only so  long  as
annuity payments begin not later than one year after the owner's death. If there
is  no designated beneficiary,  then the entire  interest in a  contract must be
distributed within five  years after the  owner's death. If  the annuitant  dies
after  annuity  payments  have  begun, any  payments  received  by  a non-spouse
beneficiary must be distributed at least as rapidly as under the method  elected
by the annuitant as of the date of death.
  If  any portion of the contract interest  is payable to the owner's designated
beneficiary who is also the surviving spouse of the owner, 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 that 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 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 date for annuity payments to begin.
 
D.  PURCHASE PAYMENTS, VALUE OF THE CONTRACT AND TRANSFERS
 
1.  CREDITING ACCUMULATION UNITS
During the accumulation period--the  period before annuity payments  begin--each
purchase  payment  is credited  on the  valuation date  coincident with  or next
following the date such purchase payment is  received by us at our home  office.
When the contracts are originally issued, application forms are completed by the
applicant and forwarded to our home office. We will review each application form
submitted to us for compliance with our issue criteria and, if it is accepted, a
contract will be issued.
  If  the initial purchase payment is  accompanied by an incomplete application,
that 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  number of accumulation  units so determined  shall not be  changed by any
subsequent change in  the value of  an accumulation  unit, but the  value of  an
accumulation unit will vary from valuation date to valuation date to reflect the
investment experience of the Funds.
  We  will determine the  value of accumulation  units on each  day on which the
Funds are valued. The  net asset value  of the Funds'  shares shall be  computed
once daily, and, in the case of Money Market Portfolio, after the declaration of
the  daily dividend, as of the primary closing time for business on the New York
Stock Exchange (as of the date hereof the primary close of trading is 3:00  p.m.
(Central  Time),  but this  time may  be  changed) on  each day,  Monday through
Friday, except (i) days on which changes  in the value of such Fund's  portfolio
securities will not materially affect the current net asset value of such Fund's
shares, (ii) days during which no such Fund's shares are tendered for redemption
and no order to
 
26
<PAGE>
   
purchase or sell such Fund's shares is received by such Fund and (iii) customary
national  business holidays on which  the New York Stock  Exchange is closed for
trading (as of  the date hereof,  New Year's  Day, Martin Luther  King Jr.  Day,
Presidents'  Day,  Good  Friday,  Memorial  Day,  Independence  Day,  Labor Day,
Thanksgiving Day  and Christmas  Day). Accordingly,  the value  of  accumulation
units  so determined 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 after
the close of business of the Exchange  will be the value determined on the  next
valuation date.
    
  In  addition  to providing  for  the allocation  of  purchase payments  to the
sub-accounts of the  Variable Annuity  Account, the contracts  also provide  for
allocation  of purchase  payments to our  General Account for  accumulation at a
guaranteed interest  rate.  Applications  received without  instructions  as  to
allocation  will be  treated as  incomplete. Upon  your written  request, values
under the  contract may  be  transferred between  our  General Account  and  the
Variable  Annuity  Account or  among the  sub-accounts  of the  Variable Annuity
Account. 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.  There is no dollar amount  limitation which is applied to transfers.
The contracts permit us to limit the frequency and amount of transfers from  our
General Account to the Variable Annuity Account.
  Currently,  except as provided below, we limit such transfers to a single such
transfer during any calendar year and to any amount which is no more than 20% of
the General Account accumulation value at the time of the transfer.
   
  However, in the case of General Account accumulation values of $1,000 or less,
we will allow a one-time transfer  of the entire accumulation value amount  from
the General Account to the sub-accounts of the Variable Annuity Account.
    
   
  Where  the contract  owner has  established a  systematic transfer arrangement
with us,  the  contract owner  may  transfer General  Account  current  interest
earnings or a specified amount from the General Account on a monthly, quarterly,
semi-annual  or  annual basis.  For  transfers of  a  specified amount  from the
General Account  the maximum  initial amount  that may  be transferred  may  not
exceed  10% of the current General Account accumulation value at the time of the
first transfer. For contracts  where the General  Account accumulation value  is
increased  during  the year  because of  transfers into  the General  Account or
additional purchase payments, made after the program is established,  systematic
transfers  are allowed  to the  extent of  the greater  of the  current transfer
amount or 10% of the then current General Account accumulation value. 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.
    
  Systematic transfer arrangements are limited to the use of a maximum of twenty
sub-accounts.
  Transfer  arrangements may be established to begin  on the 10th or 20th of any
month and  if a  transfer  cannot be  completed  it will  be  made on  the  next
available transfer date. In the absence of specific instructions, transfers will
be  made on a monthly basis and will remain active until the appropriate General
Account accumulation value or sub-account is depleted.
  Also, you or persons authorized  by you may effect  transfers, or a change  in
the  allocation of future premiums,  by means of a  telephone call. Transfers or
requests made pursuant to  such a call  are subject to  the same conditions  and
procedures  as are outlined above for  written transfer requests. During periods
of marked economic or market changes, contract owners may experience  difficulty
in  implementing a telephone transfer due to  a heavy volume of telephone calls.
In such a  circumstance, contract  owners should consider  submitting a  written
transfer  request while continuing to attempt a telephone redemption. We reserve
the  right  to  restrict  the  frequency  of--or  otherwise  modify,  condition,
terminate  or  impose  charges  upon--telephone  transfer  privileges.  For more
information on telephone transfers, contact Minnesota Mutual.
  While for some contract owners we have used a form to pre-authorize  telephone
transactions,  we now make this service  automatically available to all contract
owners.  We  will  employ  reasonable  procedures  to  satisfy  ourselves   that
instructions  received from contract owners are  genuine and, to the extent that
we do not, we  may be liable  for any losses due  to unauthorized or  fraudulent
instructions.  We  require contract  owners  or a  person  authorized by  you to
personally identify
 
                                                                              27
<PAGE>
themselves in  those telephone  conversations through  contract numbers,  social
security  numbers and such other information as we may deem to be reasonable. We
record telephone transfer instruction conversations and we provide the  contract
owners with a written confirmation of the telephone transfer.
  The  interests  of contract  owners arising  from  the allocation  of purchase
payments or  the transfer  of contract  values to  our General  Account are  not
registered  under  the Securities  Act  of 1933.  We  are not  registered  as an
investment company under the Investment  Company Act of 1940. Accordingly,  such
interests  are not subject to  the provisions of those  acts that would apply if
registration under such acts were required.
 
2.  VALUE OF THE CONTRACT
The Accumulation 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 will be advised periodically  of
the  number of accumulation units credited to the contract, the current value of
an accumulation unit, and the total value of the contract.
 
3.  ACCUMULATION UNIT VALUE
The value of an accumulation unit  for each sub-account of the Variable  Annuity
Account was set at $1.000000 on the first valuation date of the Variable Annuity
Account.  The value of an accumulation unit  on any subsequent valuation date is
determined by multiplying the value of  an accumulation unit on the  immediately
preceding  valuation  date  by  the net  investment  factor  for  the applicable
sub-account (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.
 
4.  NET INVESTMENT FACTOR FOR EACH VALUATION PERIOD
The net investment factor is an index used to measure the investment performance
of a sub-account from one valuation period to the next. For any 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 current rate of 1.25% per annum.
  The gross investment rate is equal to: (1) the net asset value per share of  a
Portfolio share held in a sub-account of the Variable Annuity Account determined
at the end of the current valuation period, plus (2) the per share amount of any
dividend or capital gain distribution by the Portfolio if the "ex-dividend" date
occurs  during the current valuation period, divided  by (3) the net asset value
per share  of  that Portfolio  share  determined at  the  end of  the  preceding
valuation period. The gross investment rate may be positive or negative.
 
E.  REDEMPTIONS
 
1.  PARTIAL WITHDRAWALS AND SURRENDER
   
Under  both  contracts, the  contracts provide  that prior  to the  date annuity
payments begin partial withdrawals may be made by you from the contract for cash
amounts of at least $250. You must make a written request for any withdrawal. In
this event,  the  accumulation  value will  be  reduced  by the  amount  of  the
withdrawal  and  any  applicable  deferred  sales  charge.  In  the  absence  of
instructions to the contrary, withdrawals will be made from the General  Account
accumulation  value and from the Variable  Annuity Account accumulation value in
the same proportion. In  the absence of instructions,  withdrawals will be  made
from  the sub-accounts on a pro rata  basis. 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  or  where  the  withdrawal  is  requested  because  of  an  excess
contribution  to a tax-qualified contract. In the absence of instructions to the
contrary, systematic withdrawals  will be made  from the sub-accounts  on a  pro
rata  basis if accumulation values  are in no more  than twenty sub-accounts. If
more  than  twenty   sub-accounts  have  accumulation   values,  we  will   need
instructions  as to those sub-accounts from  which systematic withdrawals are to
be made. For systematic  withdrawals, the maximum  number of sub-accounts  which
may be used is twenty.
    
  The  contracts provide that prior to the commencement of annuity payments, you
may elect to surrender the contract for its surrender value. You will receive in
a single  cash sum  the accumulation  value computed  as of  the valuation  date
coincident with or next following
the  date of surrender, reduced by any  applicable deferred sales charge and the
administrative charge, or you may elect an annuity.
  For more information  on the  application of  the deferred  sales charge,  see
"Sales Charges" on page 18.
 
28
<PAGE>
  Once  annuity payments have  commenced for an  annuitant, the annuitant cannot
surrender his  annuity benefit  and  receive a  single  sum settlement  in  lieu
thereof.  For a discussion of commutation rights of annuitants and beneficiaries
subsequent to the  annuity commencement  date, see "Optional  Annuity Forms"  on
page 23.
  Contract  owners may also submit their  signed written withdrawal or surrender
requests to Minnesota Mutual by facsimile (FAX) transmission. Our FAX number  is
(612)  665-7942. Transfer  instructions or changes  as to  future allocations of
premium payments may  be communicated  to us  by the  same means.  Payment of  a
partial  withdrawal or  surrender will  be made  to you  within 7  days after we
receive your completed request.
 
2.  RIGHT OF CANCELLATION
You should read the contract carefully as soon as it is received. You may cancel
the purchase of a contract within ten  days after its delivery, for any  reason,
by  giving us  written notice  at 400 Robert  Street North,  St. Paul, Minnesota
55101-2098, of  an  intention  to  cancel. If  the  contract  is  cancelled  and
returned, we will refund to you 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 you within seven days after  we
receive notice of cancellation.
   
  In  some states, such as California, the  free look period may be extended. In
California, the free look period is extended to thirty days' time. Those  rights
are subject to change and may vary among the states.
    
  The  liability of the Variable Annuity  Account under the foregoing is limited
to the  accumulation value  of  the contract  at the  time  it is  returned  for
cancellation.  Any additional amounts necessary to  make our refund to you equal
to the purchase payments will be made by us.

FEDERAL TAX STATUS
 
INTRODUCTION
   
The discussion contained herein is general in nature and is not intended as  tax
advice. Each person concerned should consult a competent tax adviser. No attempt
is  made to consider any  applicable state or other  tax laws. In addition, this
discussion is based on our understanding of federal income tax laws as they  are
currently  interpreted. No  representation is  made regarding  the likelihood of
continuation of current income  tax laws or the  current interpretations of  the
Internal  Revenue Service. The Contract may  be purchased on a non-tax qualified
basis ("Non-Qualified  Contract")  or  purchased and  used  in  connection  with
certain  retirement arrangements entitled to  special income tax treatment under
section 401(a), 403(b), 408(b), 408A or 457 of the Code ("Qualified  Contract").
The  ultimate  effect  of federal  income  taxes  on the  amounts  held  under a
Contract, on  annuity payments,  and on  the economic  benefit to  the  Contract
Owner,  the Annuitant, or  the beneficiary may  depend on the  tax status of the
individual concerned.
    
  We are taxed as  a "life insurance company"  under the Internal Revenue  Code.
The  operations of the  Variable Annuity Account  form a part  of, and are taxed
with, our other business activities. Currently, no federal income tax is payable
by us on income dividends received by the Variable Annuity Account or on capital
gains arising  from  the Variable  Annuity  Account's activities.  The  Variable
Annuity  Account is not taxed as a "regulated investment company" under the Code
and it does 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 imposed  on increases in  the
value  of a contract until distribution occurs,  either in the form of a payment
in a single sum or  as annuity payments under the  annuity option elected. As  a
general  rule, deferred annuity contracts held  by a corporation, trust or other
similar entity,  as opposed  to a  natural person,  are not  treated as  annuity
contracts  for federal tax purposes. The  investment income on such contracts is
taxed as  ordinary income  that  is received  or accrued  by  the owner  of  the
contract during the taxable year.
  For  payments made in the event of a full surrender of an annuity, the taxable
portion is generally  the amount  in excess of  the cost  basis (i.e.,  purchase
payments) of the contract. Amounts withdrawn from the variable annuity contracts
not  part of  a qualified  program are  treated first  as taxable  income to the
extent of the excess of the contract value over the purchase payments made under
the contract. Such taxable portion is taxed at ordinary income tax rates.
   
  In the case of a withdrawal under  an annuity that is part of a  tax-qualified
retirement  plan, a portion of the amount received is taxable based on the ratio
of the "investment in the contract"
    
 
                                                                              29
<PAGE>
to the individual's balance in the  retirement plan, generally the value of  the
annuity.  The "investment in  the contract" generally equals  the portion of any
deposits made by or on  behalf of an individual under  an annuity which was  not
excluded  from  the gross  income  of the  individual.  For annuities  issued in
connection with qualified plans, the "investment in the contract" can be zero.
  For annuity payments, the taxable portion is generally determined by a formula
that establishes the  ratio that the  cost basis  of the contract  bears to  the
expected  return  under the  contract. Such  taxable part  is taxed  at ordinary
income rates.
  If a taxable  distribution is  made under  the variable  annuity contracts,  a
penalty  tax of 10%  of the amount  of the taxable  distribution may apply. This
additional tax does  not apply  where the  taxpayer is  59 1/2  or older,  where
payment  is made on  account of the  taxpayer's disability, or  where payment is
made by reason of the death of the owner, and in certain other circumstances.
  The Code also provides an exception  to the penalty tax for distributions,  in
periodic payments, of substantially equal installments, be made for the life (or
life expectancy) of the taxpayer or the joint lives (or joint life expectancies)
of the taxpayer and beneficiary.
  For  some types of qualified  plans, other tax penalties  may apply to certain
distributions.
  A transfer of  ownership of  a contract, the  designation of  an annuitant  or
other  payee  who is  not  also the  contract owner,  or  the assignment  of the
contract may result in certain income  or gift tax consequences to the  contract
owner  that are  beyond the scope  of this  discussion. A contract  owner who is
contemplating any  such transfer,  designation or  assignment should  consult  a
competent  tax  adviser  with  respect  to the  potential  tax  effects  of that
transaction.
  For purposes of determining a contract owner's gross income, the Code provides
that all 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. For further information on these rules, see your tax adviser.
 
DIVERSIFICATION REQUIREMENTS
Section 817(h)  of  the  Code  authorizes  the  Treasury  to  set  standards  by
regulation  or otherwise for the investments  of the Variable Annuity Account to
be "adequately  diversified" in  order for  the  contract to  be treated  as  an
annuity contract for Federal tax purposes. The Variable Annuity Account, through
the  Fund, intends to comply with the diversification requirements prescribed in
Regulations Section 1.817-5, which affect how the Fund's assets may be invested.
Although the investment adviser is  an affiliate of Minnesota Mutual,  Minnesota
Mutual  does not  have control  over the  Fund or  its investments. Nonetheless,
Minnesota Mutual believes that each Portfolio of the Fund in which the  Variable
Annuity Account owns shares will be operated in compliance with the requirements
prescribed by the Treasury.
  In  certain  circumstances,  owners  of  variable  annuity  contracts  may  be
considered the owners,  for federal income  tax purposes, of  the assets of  the
separate account used to support their contracts. In those circumstances, income
and  gains from the separate account assets  would be includable in the variable
annuity contract owner's gross income. The  IRS has stated in published  rulings
that  a variable contract owner will be considered the owner of separate account
assets if the contract owner possesses  incidents of ownership in those  assets,
such as the ability to exercise investment control over the assets. The Treasury
Department  has also announced,  in connection with  the issuance of regulations
concerning investment diversification,  that those regulations  "do not  provide
guidance   concerning  the  circumstances  in  which  investor  control  of  the
investments of a  segregated asset  account may  cause the  investor (i.e.,  the
contract  owner), rather than the insurance company,  to be treated as the owner
of the assets in the account." This announcement also states that guidance would
be issued by way of regulations or rulings on the "extent to which policyholders
may direct their investments to particular subaccounts without being treated  as
owners  of the underlying  assets." As of  the date of  this Prospectus, no such
guidance has been issued.
  The ownership  rights under  the contract  are similar  to, but  different  in
certain  respects from, those  described by the  IRS in rulings  in which it was
determined that contract owners were not owners of separate account assets.  For
example, the owner of a contract has the choice of several sub-accounts in which
to  allocate  net purchase  payments and  contract  values, and  may be  able to
transfer  among  sub-accounts  more  frequently  than  in  such  rulings.  These
differences  could result in a contract owner  being treated as the owner of the
assets of the Variable Annuity Account.  In addition, Minnesota Mutual does  not
know what
 
30
<PAGE>
standards  will be set  forth, if any,  in the regulations  or rulings which the
Treasury Department has stated it  expects to issue. Minnesota Mutual  therefore
reserves  the right to modify the contract  as necessary to attempt to prevent a
contract owner from being considered the owner of a pro rata share of the assets
of the Variable Annuity Account.
 
REQUIRED DISTRIBUTIONS
In order to be treated as an  annuity contract for federal income tax  purposes,
Section  72(s)  of  the Code  requires  any nonqualified  contract  issued after
January 18, 1985 to provide  that (a) if an owner  dies on or after the  annuity
starting date but prior to the time the entire interest in the contract has been
distributed, the remaining portion of such interest will be distributed at least
as rapidly as under the method of distribution being used as of the date of that
owner's  death; and (b) if an owner dies prior to the annuity starting date, the
entire interest in the contract must be distributed within five years after  the
date  of the owner's death. These  requirements shall be considered satisfied if
any portion of the owner's interest which is payable to or for the benefit of  a
"designated  beneficiary" is  distributed over the  life of  such beneficiary or
over a period not extending beyond  the life expectancy of that beneficiary  and
such  distributions begin  within one  year of  that owner's  death. The owner's
"designated beneficiary" is the person designated by such owner as a beneficiary
and to whom ownership of  the contract passes by reason  of death. It must be  a
natural  person.  However,  if  the  owner's  "designated  beneficiary"  is  the
surviving spouse of the owner, the contract may be continued with the  surviving
spouse as the new owner.
  Nonqualified  contracts issued after January 18, 1985 contain provisions which
are intended  to comply  with the  requirements of  Section 72(s)  of the  Code,
although  no regulations interpreting  these requirements have  yet been issued.
Minnesota Mutual intends to review such provisions and modify them if  necessary
to  assure that  they comply  with the requirements  of Code  Section 72(s) when
clarified by regulation or otherwise.
  Other rules may apply to qualified contracts.
 
TAXATION OF DEATH BENEFIT PROCEEDS
Amounts may be distributed from  a contract because of  the death of the  owner.
Generally,  such  amounts  are includable  in  the  income of  the  recipient as
follows: (1) if distributed in a lump sum, they are taxed in the same manner  as
a  full surrender  of the  contract, as described  above, or  (2) if distributed
under an annuity option, they are taxed in the same manner as annuity  payments,
as described above.
 
POSSIBLE CHANGES IN TAXATION
   
Legislation  has been proposed in 1998  that, if enacted, would adversely modify
the federal taxation of  certain insurance and  annuity contracts. For  example,
one  proposal would  tax transfers  among investment  options and  tax exchanges
involving variable contracts. A second proposal would reduce the "investment  in
the  contract" under cash value life  insurance and certain annuity contracts by
certain amounts,  thereby  increasing  the  amount of  income  for  purposes  of
computing  gain. Although the likelihood of there being any change is uncertain,
there is always the  possibility that the tax  treatment of the Contracts  could
change  by legislation or  other means. Moreover,  it is also  possible that any
change could  be  retroactive (that  is,  effective prior  to  the date  of  the
change).   You  should  consult  a  tax  adviser  with  respect  to  legislative
developments and their effect on the Contract.
    
 
TAX QUALIFIED PROGRAMS
   
The annuity is  designed for  use with several  types of  retirement plans  that
qualify  for special tax treatment. The tax rules applicable to participants and
beneficiaries in retirement  plans vary according  to the type  of plan and  the
terms  and  conditions  of the  plan.  Special  favorable tax  treatment  may be
available for  certain types  of contributions  and distributions.  Adverse  tax
consequences  may  result  from  contributions in  excess  of  specified limits;
distributions prior to age 59 1/2 (subject to certain exceptions); distributions
that do  not conform  to  specified minimum  distribution  rules; and  in  other
specified circumstances.
    
  We  make no  attempt to  provide more  than general  information about  use of
annuities with the various  types of retirement  plans. Owners and  participants
under  retirement plans  as well as  annuitants and  beneficiaries are cautioned
that the  rights of  any person  to any  benefits under  annuities purchased  in
connection  with these plans may  be subject to the  terms and conditions of the
plans themselves, regardless of the terms  and conditions of the annuity  issued
in  connection with such a  plan. Some retirement plans  are subject to transfer
restrictions, distribution and other requirements that are not incorporated into
the annuity or our annuity  administration procedures. Owners, participants  and
beneficiaries  are responsible for determining that contributions, distributions
and other transactions with respect to the annuities comply with applicable law.
Purchasers of annuities for use with any
 
                                                                              31
<PAGE>
retirement plan should consult their legal counsel and tax adviser regarding the
suitability of the contract.
   
  For qualified plans under Section 401(a),  403(b), and 457, the Code  requires
that distributions generally must commence no later than the later of April 1 of
the  calendar  year following  the calendar  year  in which  the Owner  (or plan
participant) (i) reaches  age 70  1/2 or  (ii) retires, and  must be  made in  a
specified  form or manner.  If the plan  participant is a  "5 percent owner" (as
defined in the Code), distributions generally  must begin no later than April  1
of  the calendar year  following the calendar  year in which  the Owner (or plan
participant)  reaches  age  70   1/2.  For  IRAs   described  in  Section   408,
distributions  generally must commence no later than the later of April 1 of the
calendar  year  following  the  calendar  year  in  which  the  Owner  (or  plan
participant)  reaches age 70  1/2. Roth IRAs  under Section 408A  do not require
distributions at any time prior to the Owner's death.
    
 
PUBLIC SCHOOL SYSTEMS AND CERTAIN TAX EXEMPT ORGANIZATIONS
Under Code Section 403(b),  payments made by public  school systems and  certain
tax  exempt organizations to purchase annuity  contracts for their employees are
excludable  from  the  gross  income   of  the  employee,  subject  to   certain
limitations.  However, these payments  may be subject  to FICA (Social Security)
taxes.
  Code Section 403(b)(11) restricts the  distribution under Code Section  403(b)
annuity  contracts of: (1) elective contributions  made in years beginning after
December 31, 1988; (2) earnings on those contributions; and (3) earnings in such
years on amounts  held as of  the last  year beginning before  January 1,  1989.
Distribution  of  those  amounts may  only  occur  upon death  of  the employee,
attainment of  age 59  1/2, separation  from service,  disability, or  financial
hardship.  In addition, income attributable to elective contributions may not be
distributed in the case of hardship.
 
INDIVIDUAL RETIREMENT ANNUITIES
   
Section 408  of  the Code  permits  eligible  individuals to  contribute  to  an
Individual  Retirement  Annuity,  hereinafter  referred to  as  an  "IRA". Also,
distributions from certain other types of  qualified plans may be "rolled  over"
on  a tax-deferred basis into an IRA. The sale of a Contract for use with an IRA
may be  subject  to special  disclosure  requirements of  the  Internal  Revenue
Service.  Purchasers  of a  Contract for  use  with IRAs  will be  provided with
supplemental information  required by  the Internal  Revenue Services  or  other
appropriate agency. Such purchasers will have the right to revoke their purchase
within  7 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 of 100% of the Owner's adjusted gross
income and may be deductible in whole  or in part depending on the  individual's
income.  The  limit  on the  amount  contributed to  an  IRA does  not  apply to
distributions from certain other types of qualified plans that are "rolled over"
on  a  tax-deferred  basis  into  an  IRA.  Amounts  in  the  IRA  (other   than
nondeductible   contributions)  are   taxed  when  distributed   from  the  IRA.
Distributions prior to age 59 1/2 (unless certain exceptions apply) are  subject
to a 10% penalty tax.
    
 
   
SIMPLIFIED EMPLOYEE PENSION (SEP) IRAS
    
   
Employers  may  establish  Simplified  Employee Pension  (SEP)  IRAs  under Code
section 408(k) to  provide IRA contributions  on behalf of  their employees.  In
addition to all of the general Code rules governing IRAs, such plans are subject
to   certain   Code  requirements   regarding   participation  and   amounts  of
contributions.
    
 
   
SIMPLE IRAS
    
   
Beginning January 1, 1997, certain small employers may establish Simple IRAs  as
provided by Section 408(p) of the Code, under which employees may elect to defer
up  to $6,000 (as increased  for cost of living  adjustments) as a percentage of
compensation.  The  sponsoring   employer  is  required   to  make  a   matching
contribution  on behalf of  contributing employees. Distributions  from a Simple
IRA are subject to the same restrictions that apply to IRA distributions and are
taxed as ordinary income. Subject to certain exceptions, premature distributions
prior to age 59 1/2 are subject to a 10% penalty tax, which is increased to  25%
if  the distribution occurs within the first two years after the commencement of
the employee's participation in the plan.
    
 
   
ROTH IRAS
    
   
Effective January 1,  1998, section 408A  of the Code  permits certain  eligible
individuals  to contribute to a Roth IRA. Contributions to a Roth IRA, which are
subject to certain limitations, are not deductible  and must be made in cash  or
as
    
 
32
<PAGE>
   
a  rollover or transfer from  another Roth IRA or other  IRA. A rollover from or
conversion of an IRA to a Roth IRA may be subject to tax and other special rules
may apply.  You should  consult a  tax adviser  before combining  any  converted
amounts  with any other  Roth IRA contributions,  including any other conversion
amounts from other tax  years. Distributions from a  Roth IRA generally are  not
taxed,  except that,  once aggregate  distributions exceed  contributions to the
Roth IRA, income tax and a 10%  penalty tax may apply to distributions made  (1)
before age 59 1/2 (subject to certain exceptions) or (2) during the five taxable
years starting with the year in which the first contribution is made to the Roth
IRA.
    
 
CORPORATE PENSION AND PROFIT-SHARING PLANS 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,  investments are  owned by  the
sponsoring  employer and are subject  to the claims of  the general creditors of
the employer and depending on the terms of the particular plan, the employer may
be entitled to draw  on deferred amounts for  purposes unrelated to its  Section
457  plan obligations. In general, all amounts received under a Section 457 plan
are taxable and are subject to federal income tax withholding as wages.
 
WITHHOLDING
In general,  distributions from  annuities  are subject  to federal  income  tax
withholding  unless the  recipient elects  not to  have tax  withheld. Different
rules may apply  to payments delivered  outside the United  States. Some  states
have enacted similar rules.
  Recent  changes  to the  Code allow  the rollover  of most  distributions from
tax-qualified plans and Section 403(b) annuities directly to other tax-qualified
plans that will accept such distributions and to individual retirement  accounts
and  individual retirement annuities. Distributions which may not be rolled over
are those which are: (1) one of a series of substantially equal annual (or  more
frequent)  payments made (a) over  the life or life  expectancy of the employee,
(b) the joint  lives or joint  expectancies of the  employee and the  employee's
designated  beneficiary, or (c) for a specified period of ten years or more; (2)
a  required  minimum  distribution;  or   (3)  the  non-taxable  portion  of   a
distribution.
  Any  distribution  eligible  for rollover,  which  may include  payment  to an
employee, an employee's  surviving spouse or  an ex-spouse who  is an  alternate
payee,  will be  subject to  federal tax  withholding at  a 20%  rate unless the
distribution is made  as a  direct rollover  to a  tax-qualified plan  or to  an
individual  retirement account or annuity. It may be noted that amounts received
by individuals which are  eligible for rollover may  still be placed in  another
tax-qualified  plan or  individual retirement  account or  individual retirement
annuity if the transaction  is completed within 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
It should be understood that the foregoing description of the federal income tax
consequences under these contracts is not exhaustive and that special rules  are
provided  with respect  to situations  not discussed  herein. It  should also be
understood that should  a plan lose  its qualified status,  employees will  lose
some  of the tax  benefits described. Statutory changes  in the Internal Revenue
Code with varying effective dates,  and regulations adopted thereunder may  also
alter the tax consequences of specific factual situations. Due to the complexity
of  the applicable laws, tax advice may  be needed by a person contemplating the
purchase of a  variable annuity contract  or exercising elections  under such  a
contract. For further information a qualified tax adviser should be consulted.

RESTRICTIONS UNDER THE TEXAS OPTIONAL RETIREMENT PROGRAM
 
Section  36.105, Title 110B of the Texas Revised Civil Statutes, consistent with
prior interpretations of  the Attorney General  of the State  of Texas,  permits
participants  in the  Texas Optional  Retirement Program  (ORP) to  redeem their
interests in a  variable annuity  contract issued under  the ORP  only upon  (1)
termination  of employment in all institutions of higher education as defined in
Texas law, (2) retirement,  or (3) death. Accordingly,  participants in the  ORP

YEAR 2000 COMPUTER PROBLEM
 
   
The  services  provided by  Minnesota  Mutual to  the  Separate Account  and its
contract owners depend on the smooth  functioning of its computer systems.  Many
computer software systems in use today cannot distinguish the year 2000 from the
year 1900 because of the way that dates are encoded, stored and calculated. That
failure  could have  a negative  impact on  the ability  of Minnesota  Mutual to
provide services to contract owners. Minnesota Mutual has been actively  working
on  necessary  changes to  its  computer systems  to  deal with  the  year 2000.
Although there  can  be  no  assurance of  complete  success,  Minnesota  Mutual
believes that it will be able to resolve these issues on a timely basis and that
there  will be no material adverse impact  on its ability to provide services to
the Separate Account.
    
   
  In addition, Minnesota Mutual's  operations could be  impacted by its  service
providers'  or suppliers' year 2000 efforts.  Minnesota Mutual has undertaken an
initiative to assess the efforts of  organizations where there is a  significant
business  relationship; however there is no assurance that Minnesota Mutual will
not be affected by year 2000 problems of other organizations.

APPENDIX A--ILLUSTRATION OF VARIABLE ANNUITY VALUES
 
The  illustration  included  in this  appendix  shows the  effect  of investment
performance on the monthly variable  annuity income. The illustration assumes  a
gross investment return, after tax, of: 0%, 6.54% and 12.00%.
   
  For  illustration purposes,  an average annual  expense equal to  2.02% of the
average daily  net  assets is  deducted  from  the gross  investment  return  to
determine  the net investment return. The net  investment return is then used to
project the  monthly  variable annuity  incomes.  The expense  charge  of  2.02%
includes:  1.25% for  mortality and  expense risk,  and an  average of  .77% for
investment management and  other fund  expenses. These expenses  are listed  for
each portfolio in the table following.
    
  The  gross and net investment rates are for illustrative purposes only and are
not a reflection of past or  future performance. Actual variable annuity  income
will  be more or less than shown if  the actual returns are different than those
illustrated.
  The illustration assumes 100% of the assets are invested in sub-account(s)  of
the  Variable Annuity Account. For comparison  purposes, a current fixed annuity
income, available through the general account is also provided. The illustration
assumes an initial interest rate, used  to determine the first variable  payment
of  4.50%.  After  the  first variable  annuity  payment,  future  payments will
increase if the annualized net rate of return exceeds the initial interest rate,
and will decrease if the annualized net rate of return is less than the  initial
interest rate.
  The  illustration provided is for a male, age 65, selecting a life and 10 year
certain annuity option  with $100,000  of non-qualified funds,  residing in  the
State  of Minnesota.  Upon request,  we will  provide a  comparable illustration
based upon the proposed annuitant's date of birth, sex, annuity option, state of
residence, type of  funds, value  of funds, and  selected gross  annual rate  of
return (not to exceed 12%).

subsidiary of Minnesota Mutual Life.  MIMLIC Asset Management Company is also 
the sole owner of the shares of Advantus Capital Management Inc., a

                                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.
The Variable Annuity Account 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, 1997 were 4.14% and
4.23%, respectively.  Yield figures quoted by the Money Market Sub-Account 
will not reflect the deduction of any applicable deferred sales charges (the 
deferred sales charges, as a percentage of the accumulation value withdrawn, 
begin as of the contract date at 9% for the flexible payment contract and at 
6% for the single payment contract, and decrease uniformly each month for 120 
months).
    

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 the Variable
Annuity Account'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.  Such quotations of cumulative total return
will not reflect the deduction of any applicable deferred sales charges.

Prior to May 3, 1993, several of the Sub-Accounts were known by different names.
The Growth Sub-Account was the Stock Sub-Account, the Asset Allocation Sub-
Account was the Managed Sub-Account, the Index 500 Sub-Account was the Index
Sub-Account and the Capital Appreciation Sub-Account was the Aggressive Growth
Sub-Account.
   
The cumulative total return figures published by the Variable Annuity Account
relating to the contracts described in the Prospectus will reflect Minnesota
Mutual's voluntary absorption of certain Fund expenses described below.  The
cumulative total returns for the Sub-Accounts for the specified periods ended
December 31, 1997 are shown in the table below.  The figures in parentheses show
what the cumulative total returns would have been had Minnesota Mutual not
absorbed Fund expenses as described.

For the period subsequent to March 9, 1987, Minnesota Mutual 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 Portfolios of the Fund, .90% of the average daily net assets of 
the Capital Appreciation and Small Company Portfolios of the Funds and 
expenses that exceed 1.00% of the average daily net assets of the 
International Stock Portfolios of the Fund exclusive of the advisory fee.  
For the period subsequent to May 2, 1994, Minnesota Mutual has voluntarily 
agreed to absorb fees and expenses that exceed .90% of the average daily net 
assets of the Value Stock Portfolios, fees and expenses that exceed .40% of 
the average daily net assets of the Maturing Government Bond Portfolios 
maturing in 2006 and 2010 and fees and expenses that exceed .20% of the 
average daily net assets of the Maturing Government Bond Portfolios maturing 
in 1998 and 2002.  Subsequent to May 1, 1998, Minnesota Mutual has 
voluntarily absorbed fees and expenses that exceed .40% of the average daily 
net assets of the Maturing Government Bond Portfolios maturing in 1998 and 
2002.  
    
   

For the period subsequent to October 1, 1997, Minnesota Mutual has 
voluntarily agreed to absorb fees and expenses that exceed .55% of the 
average daily net assets of the Index 400 Mid-Cap Portfolio, .90% of the 
average daily net assets of the Small Company Value Portfolio, 1.25% of the 
average daily net assets of the Micro-Cap Growth Portfolio, .85% of the 
average daily net assets of the Macro-Cap Value Portfolio and expenses that 
exceed 1.00% of the average daily net assets of the Global Bond Portfolio of 
the Fund exclusive of the advisory fee. For the period subsequent to May 1, 
1998, Minnesota Mutual has voluntarily agreed to absorb fees and expenses 
that exceed 90% of the average daily net assets of the Real Estate Securities 
Portfolio. There is no specified or minimum period of time during which 
Minnesota Mutual has agreed to continue its voluntary absorption of these 
expenses, and Minnesota Mutual may in its discretion cease its absorption of 
expenses at any time.  Should Minnesota Mutual cease absorbing expenses the 
effect would be to increase substantially 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 which do not reflect the deduction
of any deferred sales charges.  Such other average annual total return figures
will be calculated as described above, except that the initial $1,000 investment
will be equated to that same investment's net asset value, rather than its
surrender value, at the end of the period.  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, 1997 are shown in the
table below.  Inasmuch as no deferred sales charges are reflected in these
figures, they are the same for both the flexible premium and the single premium
contracts.  The figures in parentheses show what the average annual rates of
return, without the application of applicable deferred sales charges, would have
been had Minnesota Mutual not absorbed Fund expenses as described above.

PREDICTABILITY OF RETURN

ANTICIPATED VALUE AT MATURITY.  The maturity values of zero-coupon bonds are
specified at the time the bonds are issued, and this feature, combined with the
ability to calculate yield to maturity, has made these instruments popular
investment vehicles for investors seeking reliable investments to meet long-term
financial goals.

Each Maturing Government Bond Portfolio of the Fund consists primarily of zero-
coupon bonds but is actively managed to accommodate contract owner activity and
to take advantage of perceived market opportunities.  Because of this active
management approach, there is no guarantee that a certain price per share of a
Maturing Government Bond Portfolio, or a certain price per unit of the
corresponding Sub-Account, will be attained by the time a Portfolio is
liquidated.  Instead, the Fund attempts to track the price behavior of a
directly held zero-coupon bond by:

     (1)  Maintaining a weighted average maturity within each Maturing
          Government Bond Portfolio's target maturity year;

     (2)  Investing at least 90% of assets in securities that mature within one
          year of that Portfolio's target maturity year;

     (3)  Investing a substantial portion of assets in Treasury STRIPS (the most
          liquid Treasury zero);

     (4)  Under normal conditions, maintaining a nominal cash balance;

     (5)  Executing portfolio transactions necessary to accommodate net contract
          owner purchases or redemptions on a daily basis; and

     (6)  Whenever feasible, contacting several U.S. government securities
          dealers for each intended transaction in an effort to obtain the best
          price on each transaction.

These measures enable the Company to calculate an anticipated value at maturity
(AVM) for each unit of a Maturing Government Bond Sub-Account, calculated as of
the date of purchase of such unit, that approximates the price per unit that
such unit will achieve by the weighted average maturity date of the underlying
Portfolio.  The AVM calculation for each Maturing Government Bond Sub-Account is
as follows:

                      AVM = P(1 + AGR/2) to the power of 2T

where P = the Sub-Account's current price per unit; T = the Sub-Account's
weighted average term to maturity in years; and AGR = the anticipated growth
rate.

This calculation assumes an expense ratio and a portfolio composition for the
underlying Maturing Government Bond Portfolio that remain constant for the life
of such Portfolio.  Because the Portfolio's expenses and composition do not
remain constant, however, the Company may

                                      -12-

<PAGE>

calculate AVM for each Maturing Government Bond Sub-Account on any day on which
the underlying Maturing Government Bond Portfolio is valued.  Such an AVM is
applicable only to units purchased on that date.

In addition to the measures described above, which the adviser believes are
adequate to assure close correspondence between the price behavior of each
Portfolio and the price behavior of directly held zero-coupon bonds with
comparable maturities, the Fund expects that each Portfolio will invest at least
90% of its net assets in zero-coupon bonds until it is within four years of its
target maturity year and at least 80% of its net assets in zero-coupon
securities within two to four years of its target maturity year.  This
expectation may be altered if the market supply of zero-coupon securities
diminishes unexpectedly.

ANTICIPATED GROWTH RATE.  The Company calculates an anticipated growth rate
(AGR) for each Maturing Government Bond Sub-Account on each day on which the
underlying Portfolio is valued.  AGR is a calculation of the anticipated
annualized rate of growth for a Sub-Account unit, calculated from the date of
purchase of such unit to the Sub-Account's target maturity date.  As is the case
with calculations of AVM, the AGR calculation assumes that each underlying
Maturing Government Bond Portfolio expense ratio and portfolio composition will
remain constant.  Each Maturing Government Bond Sub-Account AGR changes from day
to day (i.e., a particular AGR calculation is applicable only to units purchased
on that date), due primarily to changes in interest rates and, to a lesser
extent, to changes in portfolio composition and other factors that affect the
value of the underlying Portfolio.

The Company expects that a contract owner who holds specific units until the
underlying Portfolio's weighted average maturity date will realize an investment
return and maturity value on those units that do not differ substantially from
the AGR and AVM calculated on the day such units were purchased.  The AGR and
AVM calculated with respect to units purchased any other date, however, may be
materially different.

confirmed to us by the respective Sub-Account mutual fund, or for Advantus 
Series Fund, Inc. (formerly MIMLIC Series Fund, Inc.), verified by 
examination of the underlying portfolios.  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.

                           NOTES TO FINANCIAL STATEMENTS

(1)  ORGANIZATION AND BASIS OF PRESENTATION

   
     The Minnesota Mutual Variable Annuity Account (the Account) was established
     on September 10, 1984 as a segregated asset account of The Minnesota Mutual
     Life Insurance Company (Minnesota Mutual) under Minnesota law and is
     registered as a unit investment trust under the Investment Company Act of
     1940 (as amended).  There are currently four types of contracts each
     consisting of one to twenty-one segregated sub-accounts.  The financial
     statements presented herein include only the segregated sub-accounts
     offered in connection with the sale of the Combination Fixed and Variable
     Annuity Contracts for Personal Retirement Plans (Multi-option Annuity) and
     Multi-Option Select.
    
     
     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 Mutual.  Contract owners allocate their variable annuity
     purchase payments to one or more of the twenty segregated sub-accounts. 
     Such payments are then invested in shares of Advantus Series Fund, Inc., 
     formerly MIMLIC Series Fund, Inc., and Templeton Variable Products Series 
     Fund (Underlying Funds).  The Advantus Series Fund, Inc. was organized by 
     Minnesota Mutual as the investment vehicle for its variable annuity 
     contracts and variable life policies.  Each of the Underlying Funds is 
     registered under the Investment Company Act of 1940 (as amended) as a

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

(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 of assets and liabilities and
     disclosure of contingent assets and liabilities at the date of the
     financial statements and the reported amounts of increases and decreases in
     net assets resulting from operations during the period.  Actual results
     could differ from those estimates.
    
     INVESTMENTS IN UNDERLYING FUNDS
     
     Investments in shares of the Underlying Funds are stated at market value
     which is the net asset value per share as determined daily by each of the
     Underlying Funds.  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 Underlying Funds are reinvested in additional shares of the
     Underlying Funds and are recorded by the segregated sub-accounts on the
     ex-dividend date.

                     MINNESOTA MUTUAL VARIABLE ANNUITY ACCOUNT

(2)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - CONTINUED
     
     FEDERAL INCOME TAXES
     
     The Account is treated as part of Minnesota Mutual for federal income tax
     purposes.  Under current interpretations of existing federal income tax
     law, no income taxes are payable on investment income or capital gain
     distributions received by the Account from the underlying Funds.
     
     CONTRACTS IN ANNUITY PAYMENT PERIOD
     
     Annuity reserves are computed for currently payable contracts according to
     the Progressive Annuity Mortality Table, using an assumed interest rate of
     3.5 percent.  Charges to annuity reserves for mortality and risk expense
     are reimbursed to Minnesota Mutual if the reserves required are less than
     originally estimated.  If additional reserves are required, Minnesota
     Mutual reimburses the Account.
     
(3)  MORTALITY AND EXPENSE AND SALES CHARGES
    
     The mortality and expense charge paid to Minnesota Mutual is computed daily
     and is equal, on an annual basis, to 1.25 percent of the average daily net
     assets of the Account.  Under certain conditions, the charge may be
     increased to 1.40 percent of the average daily net assets of the Account.
    
     A contingent deferred sales charge may be imposed on a Multi-Option Annuity
     or Multi-Option Select contract owner during the first ten years or first
     seven years, respectively, if a contract's accumulation value is reduced by
     a withdrawal or surrender.  Total sales charges deducted from redemption
     proceeds for the years ended December 31, 1997 and 1996 amounted to
     $1,743,977 and $1,677,688, respectively.

 INDEPENDENT AUDITORS' REPORT
The Board of Trustees
The Minnesota Mutual Life Insurance Company
 
  We have audited the accompanying consolidated balance sheets of The Minnesota
Mutual Life Insurance Company and subsidiaries as of December 31, 1997 and
1996, and the related consolidated statements of operations and policyowners'
surplus and cash flows for each of the years in the three-year period ended
December 31, 1997. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of The
Minnesota Mutual Life Insurance Company and subsidiaries as of December 31,
1997 and 1996, and the results of their operations and their cash flows for
each of the years in the three-year period ending December 31, 1997 in
conformity with generally accepted accounting principles.
  Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplementary information included
in the accompanying schedules is presented for purpose of additional analysis
and is not a required part of the basic financial statements. Such information
has been subjected to the auditing procedures applied in the audits of the
basic financial statements and, in our opinion, is fairly stated in all
material respects in relation to the basic financial statements taken as a
whole.

 THE MINNESOTA MUTUAL LIFE INSURANCE COMPANY AND SUBSIDIARIES
 
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(1) NATURE OF OPERATIONS
 
The Minnesota Mutual Life Insurance Company (the Company), both directly and
through its subsidiaries, provides a diversified array of insurance and
financial products and services designed principally to protect and enhance the
long-term financial well-being of individuals and families.
  The Company's strategy is to be successful in carefully selected niche
markets, primarily in the United States, while focusing on the retention of
existing business and the maintenance of profitability. To achieve this
objective, the Company has divided its businesses into four strategic business
units which focus on various markets: Individual, Financial Services, Group,
and Pension. Revenues in 1997 for these business units were $854,192,000,
$284,222,000, $232,619,000 and $114,324,000, respectively. Additional revenues
of $185,430,000, were reported by the Company's subsidiaries.
  At December 31, 1997, the Company was one of the 12 largest mutual life
insurance company groups in the United States, as measured by total assets. The
Company serves nearly seven million people through more than 4,000 associates
located at its St. Paul headquarters and in 81 general agencies and 43 regional
offices throughout the United States.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Basis of Presentation
The accompanying consolidated financial statements have been prepared in
accordance with generally accepted accounting principles (GAAP), which vary in
certain respects from accounting practices prescribed or permitted by state
insurance regulatory authorities. The consolidated financial statements include
the accounts of The Minnesota Mutual Life Insurance Company and its
subsidiaries (collectively, "the Company"). All material intercompany
transactions and balances have been eliminated.
  The preparation of financial statements in conformity with GAAP requires
management to make certain estimates and assumptions that affect reported
assets and liabilities, including reporting or disclosure of contingent assets
and liabilities as of the balance sheet date and the reported amounts of
revenues and expenses during the reporting period. Future events, including
changes in mortality, morbidity, interest rates, and asset valuations, could
cause actual results to differ from the estimates used in the financial
statements.
 
Insurance Revenues and Expenses
Premiums on traditional life products, which include individual whole life and
term insurance and immediate annuities, are credited to revenue when due. For
accident and health and group life products, premiums are credited to revenue
over the contract period as earned. Benefits and expenses are recognized in
relation to premiums over the contract period via a provision for future policy
benefits and the amortization of deferred policy acquisition costs.
  Nontraditional life products include individual adjustable and variable life
insurance and group universal and variable life insurance. Revenue from
nontraditional life products and deferred annuities is comprised of policy and
contract fees charged for the cost of insurance, policy administration and
surrenders. Expenses include the portion of claims not covered by and interest
credited to the related policy and contract account balances. Policy
acquisition costs are amortized relative to estimated gross profits or margins.
 
Deferred Policy Acquisition Costs
The costs of acquiring new and renewal business, which vary with and are
primarily related to the production of new and renewal business, are generally
deferred to the extent recoverable from future premiums or expected gross
profits. Deferrable costs include commissions, underwriting expenses and
certain other selling and issue costs.
  For traditional life, accident and health and group life products, deferred
acquisition costs are amortized over the premium paying period in proportion to
the ratio of annual premium revenues to ultimate anticipated

premium revenues. The ultimate premium revenues are estimated based upon the
same assumptions used to calculate the future policy benefits.
  For nontraditional life products and deferred annuities, deferred acquisition
costs are amortized over the estimated lives of the contracts in relation to
the present value of estimated gross profits from surrender charges and
investment, mortality and expense margins.
  Deferred acquisition costs amortized were $128,176,000, $125,978,000 and
$104,940,000 for the years ended December 31, 1997, 1996 and 1995,
respectively.
 
Finance Charge Income and Receivables
Finance charge income represents fees and interest charged on consumer loans.
The Company uses the interest (actuarial) method of accounting for finance
charges and interest on finance receivables. Accrual of finance charges and
interest on the smaller balance homogeneous finance receivables is suspended
when a loan is contractually delinquent for more than 60 days and is
subsequently recognized when received. Accrual is resumed when the loan is
contractually less than 60 days past due. Finance charges and interest is
suspended when a loan is considered by management to be impaired. Loan
impairment is measured based on the present value of expected future cash flows
discounted at the loan's effective interest rate, or as a practical expedient,
at the observable market price of the loan or the fair value of the collateral
if the loan is collateral dependent. When a loan is identified as impaired,
interest previously accrued in the current year is reversed. Interest payments
received on impaired loans are generally applied to principal unless the
remaining principal balance has been determined to be fully collectible. An
allowance for uncollectible amounts is maintained by direct charges to
operations at an amount which management believes, based upon historical losses
and economic conditions, is adequate to absorb probable losses on existing
receivables that may become uncollectible. The reported receivables are net of
this allowance.
 
Valuation of Investments
Fixed maturity securities (bonds) which the Company has the positive intent and
ability to hold to maturity are classified as held-to-maturity and are carried
at amortized cost, net of write-downs for other than temporary declines in
value. Premiums and discounts are amortized or accreted over the estimated
lives of the securities based on the interest yield method. Fixed maturity
securities which may be sold prior to maturity are classified as available-for-
sale and are carried at fair value.
  Equity securities (common stocks and preferred stocks) are carried at fair
value. Equity securities also include initial contributions to affiliated
registered investment funds that are managed by a subsidiary of the Company.
These contributions are carried at the market value of the underlying net
assets of the funds.
  Mortgage loans are carried at amortized cost less an allowance for
uncollectible amounts. Premiums and discounts are amortized or accreted over
the terms of the mortgage loans based on the interest yield method. A mortgage
loan is considered impaired if it is probable that contractual amounts due will
not be collected. Impaired mortgage loans are valued at the fair value of the
underlying collateral. Interest income on impaired mortgage loans is recorded
on an accrual basis. However, when the likelihood of collection is doubtful,
interest income is recognized when received.
  Fair values of fixed maturity securities and equity securities are based on
quoted market prices, where available. If quoted market prices are not
available, fair values are estimated using values obtained from independent
pricing services which specialize in matrix pricing and modeling techniques for
estimating fair values. Fair values of mortgage loans are based upon discounted
cash flows, quoted market prices and matrix pricing.
  Real estate is carried at cost less accumulated depreciation and an allowance
for estimated losses. Accumulated depreciation on real estate at December 31,
1997 and 1996, was $6,269,000 and $5,968,000, respectively.
  Policy loans are carried at the unpaid principal balance.
 
                                                                              65

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
Derivative Financial Instruments
The Company entered into equity swaps in 1996 as part of an overall risk
management strategy. The swaps were used to hedge exposure to market risk on
$400,000,000 of the Company's common stock portfolio. The swaps were based upon
certain stock indices. If, at the time of settlement for a particular swap, the
designated stock index had fallen below a specified level, the counterparty
would pay the Company an amount based upon the decline in the index and the
stock portfolio value protected by the swap. If, at the time of settlement, the
designated stock index had risen, the Company would pay the counterparty an
amount based upon the increase in the index and 25% of the stock portfolio
value protected by the swap. The equity swaps were settled with the
counterparties in August of 1997.
  The swaps were carried at fair value, which were based upon dealer quotes.
Changes in fair value were recorded directly in policyowners' surplus. Upon
settlement of the swaps, gains or losses were recognized in income. The Company
realized a loss of approximately $31 million in 1997, upon settlement of these
equity swaps.
  The Company began investing in international bonds denominated in foreign
currencies in 1997. The Company uses forward foreign exchange currency
contracts as part of its risk management strategy for international
investments. The forward foreign exchange currency contracts are used to reduce
market risks from changes in foreign exchange rates. These forward foreign
exchange currency contracts are agreements to purchase a specified amount of
one currency in exchange for a specified amount of another currency at a future
point in time at a foreign exchange currency rate agreed upon on the contract
open date. No cash is exchanged at the outset of the contract and no payments
are made by either party until the contract close date. On the contract close
date the contracted amount of the purchased currency is received from the
counterparty and the contracted amount of the sold currency is sent to the
counterparty. These contracts are generally short-term in nature and there is
no material exposure to the Company at December 31, 1997.
 
Capital Gains and Losses
Realized and unrealized capital gains and losses are determined on the specific
identification method. Write-downs of held-to-maturity securities and the
provision for credit losses on mortgage loans and real estate are recorded as
realized losses.
  Changes in the fair value of fixed maturity securities available-for-sale and
equity securities are recorded as a separate component of policyowners'
surplus, net of taxes and related adjustments to deferred policy acquisition
costs and unearned policy and contract fees.
 
Property and Equipment
Property and equipment are carried at cost, net of accumulated depreciation of
$90,926,000 and $81,962,000 at December 31, 1997 and 1996, respectively.
Buildings are depreciated over 40 years and equipment is generally depreciated
over 5 to 10 years. Depreciation expenses for the years ended December 31,
1997, 1996 and 1995, were $8,965,000, $6,454,000 and $5,941,000, respectively.
 
Separate Accounts
Separate account assets and liabilities represent segregated funds administered
and invested by the Company for the exclusive benefit of pension, variable
annuity and variable life insurance policyowners and contractholders. Assets
consist principally of marketable securities and both assets and liabilities
are reported at fair value, based upon the market value of the investments held
in the segregated funds. The Company receives administrative and investment
advisory fees for services rendered on behalf of these accounts.
  The Company periodically invests money in its separate accounts. The market
value of such investments is included with separate account assets and amounted
to $46,293,000 and $14,882,000 as of December 31, 1997 and 1996, respectively.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
Policyowner Liabilities
Policy and contract account balances represent the net accumulation of funds
associated with nontraditional life products and deferred annuities. Additions
to the account balances include premiums, deposits and interest credited by the
Company. Decreases in the account balances include surrenders, withdrawals,
benefit payments, and charges assessed for the cost of insurance, policy
administration and surrenders.
  Future policy and contract benefits are comprised of reserves for traditional
life, group life, and accident and health products. The reserves were
calculated using the net level premium method based upon assumptions regarding
investment yield, mortality, morbidity, and withdrawal rates determined at the
date of issue, commensurate with the Company's experience. Provision has been
made in certain cases for adverse deviations from these assumptions.
  Other policyowner funds are comprised of dividend accumulations, premium
deposit funds and supplementary contracts without life contingencies.
 
Participating Business
Substantially all of the Company's premium revenues are derived from
participating policies. Dividends and other discretionary payments are declared
by the Board of Trustees based upon actuarial determinations, which take into
consideration current mortality, interest earnings, expense factors, and
federal income taxes. Dividends are recognized as expenses consistent with the
recognition of premiums.
 
Income Taxes
Current income taxes are charged to operations based upon amounts estimated to
be payable as a result of taxable operations for the current year. Deferred
income tax assets and liabilities are recognized for the future tax
consequences attributable to the differences between financial statement
carrying amounts and income tax bases of assets and liabilities.
 
Reinsurance Recoverables
Insurance liabilities are reported before the effects of ceded reinsurance.
Reinsurance recoverables represent amounts due from reinsurers for paid and
unpaid benefits, expense reimbursements, prepaid premiums and future policy
benefits.
 
Reclassifications
Certain 1996 and 1995 financial statement balances have been reclassified to
conform with the 1997 presentation.

  At December 31, 1997, the recorded investment in mortgage loans that were
considered to be impaired was $18,400 before allowance for credit losses. These
impaired loans, due to adequate fair market value of underlying collateral, do
not have an allowance for credit losses.
  At December 31, 1996, the recorded investment in mortgage loans that were
considered to be impaired was $6,518,000 before allowance for credit losses.
Included in this amount is $2,225,000 of impaired loans, for which the related
allowance for credit losses is $395,000 and $4,293,000 of impaired loans that,
as a result of adequate fair market value of underlying collateral, do not have
an allowance for credit losses.
  In addition to the allowance for credit losses on impaired mortgage loans, a
general allowance for credit losses was established for potential impairments
in the remainder of the mortgage loan portfolio. The general allowance was
$1,500,000 at December 31, 1997 and 1996.

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

  The liability for unpaid accident and health claims and claim adjustment
expenses is included in future policy and contract benefits and pending policy
and contract claims on the consolidated balance sheets.
  As a result of changes in estimates of claims incurred in prior years, the
accident and health claims and claim adjustment expenses incurred increased
(decreased) by $7,809, $4,821 and ($4,014) in 1997, 1996 and 1995,
respectively. These amounts are the result of normal reserve development
inherent in the uncertainty of establishing the liability for unpaid accident
and health claims and claim adjustment expenses.
 
(8) EMPLOYEE BENEFIT PLANS
 
Pension Plans
The Company has noncontributory defined benefit retirement plans covering
substantially all employees and certain agents. Benefits are based upon years
of participation and the employee's average monthly compensation or the agent's
adjusted annual compensation. Plan assets are comprised of mostly stocks and
bonds, which are held in the general and separate accounts of the Company and
administered under group annuity contracts issued by the Company. The Company's
funding policy is to contribute annually the minimum amount required by
applicable regulations. The Company also has an unfunded noncontributory
defined benefit retirement plan, which provides certain employees with benefits
in excess of limits for qualified retirement plans.
  Net periodic pension cost for the years ended December 31 included the
following components:

  A weighted average discount rate of 7.5% and a weighted average rate of
increase in future compensation levels of 5.3% were used in determining the
actuarial present value of the projected benefit obligation at December 31,
1997 and 1996. The assumed long-term rate of return on plan assets was either
8.5% or 7.5%, depending on the plan.
 
Profit Sharing Plans
The Company also has profit sharing plans covering substantially all employees
and agents. The Company's contribution rate to the employee plan is determined
annually by the trustees of the Company and is applied to each participant's
prior year earnings. The Company's contribution to the agent plan is made as a
certain percentage, based upon years of service, applied to each agent's total
annual compensation. The Company recognized contributions to the plans during
1997, 1996 and 1995 of $7,173,000, $6,092,000 and $6,595,000, respectively.
Participants may elect to receive a portion of their contributions in cash.
 
Postretirement Benefits Other than Pensions
The Company also has unfunded postretirement plans that provide certain health
care and life insurance benefits to substantially all retired employees and
agents. Eligibility is determined by age at retirement and years of service
after age 30. Health care premiums are shared with retirees, and other cost-
sharing features include deductibles and co-payments.
 
  Components of net periodic postretirement benefit cost for the years ended
December 31 were as follows:

</TABLE>
 
  The discount rate used in determining the accumulated postretirement benefit
obligation for 1997 and 1996 was 7.5%. The 1997 net health care cost trend rate
was 8.5%, graded to 5.5% over 6 years, and the 1996 rate was 9.0%, graded to
5.5% over 7 years.
  The assumptions presented herein are based on pertinent information available
to management as of December 31, 1997 and 1996. Actual results could differ
from those estimates and assumptions. For example, increasing the assumed
health care cost trend rates by one percentage point in each year would
increase the postretirement benefit obligation as of December 31,1997 by
$4,323,000 and the estimated eligibility cost and interest cost components of
net periodic postretirement benefit costs for 1997 by $588,000.
 
 
(9) SALE OF SUBSIDIARY
 
On October 1, 1997, the Company sold Minnesota Fire and Casualty Company (MFC),
a wholly owned subsidiary to Harleysville Group, Inc. The Company received net
cash proceeds of approximately $33.5 million from the sale, and realized a gain
of approximately $14.5 million. HomePlus Insurance Company (HomePlus), a
previously wholly owned subsidiary of MFC, was excluded from the sale of
assets. In accordance with the agreement, prior to September 30,1997, MFC made
a distribution of private placement bonds to the Company with an amortized cost
of approximately $4.3 million and transferred all issued and outstanding shares
of HomePlus to the Company. The carrying value of the transferred shares was
approximately $5.8 million. Under an administrative services agreement with
MFC, the Company has retained MFC to provide financial and other services for
HomePlus.
 
(10) REINSURANCE
 
In the normal course of business, the Company seeks to limit its exposure to
loss on any single insured and to recover a portion of benefits paid by ceding
reinsurance to other insurance companies. To the extent that a reinsurer is
unable to meet its obligation under the reinsurance agreement, the Company
remains liable. The Company evaluates the financial condition of its reinsurers
and monitors concentrations of credit risk to minimize its exposure to
significant losses from reinsurer insolvencies. Allowances are established for
amounts deemed to be uncollectible.
  Reinsurance is accounted for over the life of the underlying reinsured
policies using assumptions consistent with those used to account for the
underlying policies.

  Reinsurance recoveries on ceded reinsurance contracts were $58,072,000,

(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, 1997 and 1996.
Although management is not aware of any factors that would significantly affect
the estimated fair value, such amounts have not been comprehensively revalued
since those dates. Therefore, estimates of fair value subsequent to the
valuation dates may differ significantly from the amounts presented herein.
Considerable judgement is required to interpret market data to develop the
estimates of fair value. The use of different market assumptions and/or
estimation methodologies may have a material effect on the estimated fair value
amounts.
  Please refer to Note 2 for additional fair value disclosures concerning fixed
maturity securities, equity securities, mortgages and derivatives. The carrying
amounts for policy loans, cash, short term investments, and finance receivables
approximate the assets' fair values.
  The interest rates on the finance receivables outstanding as of December 31,
1997 and 1996, are consistent with the rates at which loans would currently be
made to borrowers of similar credit quality and for the same maturity; as such,
the carrying value of the finance receivables outstanding as of December 31,
1997 and 1996, approximate the fair value for those respective dates.
  The fair values of deferred annuities, annuity certain contracts, and other
fund deposits, which have guaranteed interest rates and surrender charges are
estimated to be the amount payable on demand as of December 31, 1997 and 1996
as those investments contracts have no defined maturity and are similar to a
deposit liability. The amount payable on demand equates to the account balance
less applicable surrender charges. Contracts without guaranteed interest rates
and surrender charges have fair values equal to their accumulation values plus
applicable market value adjustments. The fair values of guaranteed investment
contracts and supplementary contracts without life contingencies are calculated
using discounted cash flows, based on interest rates currently offered for
similar products with maturities consistent with those remaining for the
contracts being valued.
  Rates currently available to the Company for debt with similar terms and
remaining maturities are used to estimate the fair value of notes payable.
 
                                                                              77

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

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

WHAT DOES THIS AGREEMENT PROVIDE?

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

PURCHASE PAYMENTS

ARE TRADITIONAL IRA PURCHASE PAYMENTS LIMITED?

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

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

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

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

ARE ROTH-IRA PURCHASE PAYMENTS LIMITED?

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


                                                             Minnesota Mutual 1
<PAGE>

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

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

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

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

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

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

DO PURCHASE PAYMENT LIMITATIONS APPLY TO A ROLLOVER?

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

MAY THE ANNUITANT ALWAYS MAKE PURCHASE PAYMENTS?

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


                                                             Minnesota Mutual 2
<PAGE>

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

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

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

DISTRIBUTION PROVISIONS

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

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

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

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

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

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

WHAT FORMS OF DISTRIBUTION ARE AVAILABLE FROM AN IRA?

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

(a)  a single sum payment;

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

(c)  equal or substantially equal payments over the joint lives of the annuitant
     and spouse;

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

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


                                                             Minnesota Mutual 3

<PAGE>

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

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

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

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

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

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

ARE OTHER OPTIONS AVAILABLE TO A SPOUSE BENEFICIARY?

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

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

HOW ARE LIFE EXPECTANCIES FOR CALCULATING REQUIRED DISTRIBUTIONS DETERMINED?

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

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

<PAGE>

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

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

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

WITHDRAWAL BENEFITS

ARE THERE LIMITS ON WITHDRAWALS FROM AN IRA?

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

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

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

MAY TAX PENALTIES APPLY FOR WITHDRAWALS FROM AN IRA?

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

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

<PAGE>

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

MAY TAX PENALTIES APPLY FOR WITHDRAWALS FROM ROTH-IRAS?

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

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

GENERAL INFORMATION

IS THE INTEREST OF THE ANNUITANT IN THIS CONTRACT NONFORFEITABLE?

Yes.  The entire interest of the annuitant in this contract is nonforfeitable. 
The annuitant shall possess the entire benefit provided by this contract.  This
contract is established for the exclusive benefit of the annuitant and his or
her beneficiaries.

HOW WILL DIVIDENDS BE APPLIED?

Dividends, if received, must be added to the accumulation value or applied to
increase annuity payments.

HOW WILL A REFUND OF PREMIUMS BE APPLIED?

Any refund of premiums (other than those attributable to excess purchase
payments) will be applied, before the close of the calendar year following the
year of the refund, toward the payment of future premiums or the purchase of
additional benefits.

MAY THIS AGREEMENT BE AMENDED?

Yes.  This contract may be amended as required to reflect any change in the
Code, regulations or published revenue rulings.  The annuitant will be deemed to
have consented to any such amendment.  We will promptly furnish any such
amendment to the annuitant.

This agreement is effective as of the original contract date unless a different
effective date is shown here.

                                                        SIMPLE - (IRA) AGREEMENT

WHAT DOES THIS AGREEMENT PROVIDE?

This agreement modifies the contract.  Provisions are changed before issue.  In
the event of a conflict between the provisions of this agreement and the
contract to which it is attached, the provisions of this agreement will control.
These changes will allow its use with a Savings Incentive Match Plan for
Employees (herein "SIMPLE-IRA").

PURCHASE PAYMENTS

ARE SIMPLE-IRA PURCHASE PAYMENTS LIMITED?

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

DO PURCHASE PAYMENT LIMITATIONS APPLY TO A ROLLOVER?

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

MAY THE ANNUITANT ALWAYS MAKE PURCHASE PAYMENTS?

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

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

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

DISTRIBUTION PROVISIONS

ARE THERE RULES FOR THE TIMING OF DISTRIBUTIONS?

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


                                                             Minnesota Mutual 1

<PAGE>

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

WHAT FORMS OF DISTRIBUTION ARE AVAILABLE?

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

(a)  a single sum payment;

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

(c)  equal or substantially equal payments over the joint lives of the annuitant
     and spouse;

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

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

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

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

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

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

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

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

ARE OTHER OPTIONS AVAILABLE TO A SPOUSE BENEFICIARY?

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


                                                             Minnesota Mutual 2

<PAGE>

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

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

HOW ARE LIFE EXPECTANCIES FOR CALCULATING REQUIRED DISTRIBUTIONS DETERMINED?

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

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

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

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

WITHDRAWAL BENEFITS

ARE THERE LIMITS ON WITHDRAWALS?

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

MAY TAX PENALTIES APPLY?

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

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

                                                               MINNESOTA MUTUAL

Gentlepersons:


In my capacity as counsel for The Minnesota Mutual Life Insurance Company (the
"Company"), I have reviewed certain legal matters relating to the Company's 
Separate Account entitled Minnesota Mutual Variable Annuity Account (the 
"Account") in connection with Post-Effective Amendment No. 15 to its 
Registration Statement on Form N-4.   This Post-Effective Amendment is to be 
filed by the Company and the Account with the Securities and Exchange Commission
under the Securities Act of 1933, as amended, with respect to certain variable 
annuity contracts (Securities and Exchange Commission File No. 2-97564).


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

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

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



Donald F. Gruber
Assistant General Counsel
