     The purpose of the above table is to assist the Owner in understanding  the
various costs and expenses that an Owner will bear directly or  indirectly.  The
table reflects  expenses of the Separate  Account as well as the expenses of the
Accounts in which the Separate Account invests. In certain circumstances,  state
premium taxes will also be applicable. See "Charges and Deductions."

SUMMARY

The  following   summary  should  be  read  in  conjunction  with  the  detailed
information in this  Prospectus.  This Prospectus  generally  describes only the
portion of the Contract involving the Separate Account.  For a brief description
of the Fixed  Account,  please  refer to the  heading  "Fixed  Account"  in this
Prospectus.

The Flexible  Variable  Annuity  Contract (also known as the Principal  Variable
Annuity  Contract) (the "Contract")  described in this Prospectus is designed to
provide  individuals with retirement  benefits in connection with (1) Individual
Retirement Annuity plans or programs ("IRA Plans"),  Roth IRA Plans,  Simplified
Employee Pension Plans ("SEPs"),  Salary Reduction  Simplified  Employee Pension
Plans  ("SAR/SEPs")  and Savings  Incentive Match Plan for Employees  ("SIMPLE")
IRAs  adopted  pursuant  to Section  408 of the  Internal  Revenue  Code and (2)
non-qualified retirement plans.

Minimum Investment Amount

For Contracts  issued in connection with  non-qualified  retirement  plans,  the
initial Purchase  Payment must be at least $2,500.  The initial Purchase Payment
for all  other  Contracts  must  be at  least  $1,000.  The  minimum  subsequent
investment  is  $100.  A  $100  monthly   minimum  for  initial  and  subsequent
investments is available for Contracts to which Purchase  Payments are made on a
monthly basis through a payroll  deduction plan or through an account of bank or
similar financial  institution under an Automatic Investment Program.  Forms and
preauthorized check agreements to establish an Automatic  Investment Program are
available from Princor Financial Services  Corporation.  For Contracts which are
issued in connection with a retirement plan covering more than four people,  the
initial and subsequent  monthly Purchase Payment under each Contract must at all
times  average  at  least  $100 and in no case be less  than  $50.  The  Company
reserves the right to terminate a Contract and distribute the Accumulated Value,
less any  applicable  charges,  if no  Purchase  Payments  are paid  during  two
consecutive  calendar years and the Accumulated Value or total Purchase Payments
less partial  surrenders and applicable  surrender  charges is less than $2,000.
See "Purchase Payment Limitations."

The initial  Purchase  Payment is  allocated,  as  specified by the Owner in the
Contract  application,  among  one or  more  of the  Divisions  of the  Separate
Account, or to the Fixed Account,  or to both.  Subsequent Purchase Payments are
allocated in the same way, or pursuant to different allocation  percentages that
the Owner may subsequently specify.

Separate Account Investment Options

Each  of  the  Divisions  of  the  Separate  Account  invests  in  shares  of  a
corresponding  Account  in the  Principal  Variable  Contracts  Fund,  Inc.  The
Accumulated  Value in each of the Divisions of the Separate Account will vary to
reflect the investment experience of each of the corresponding  Accounts as well
as deductions for certain charges.

Each Account has a separate and distinct investment  objective and is managed by
Principal  Management   Corporation,   ("Manager").   For  providing  investment
management  services to the Accounts of the Principal  Variable  Contracts Fund,
Inc.(the  "Fund"),  the Manager  receives  fees from each  Account  based on the
average  daily net assets of the  Account.  Each  Account also bears most of its
other expenses. A full description of Accounts and their investment  objectives,
policies  and risks can be found in the  current  Prospectus  for the  Principal
Variable Contracts Fund, Inc., which accompanies this Prospectus.

Transfers

Subject to restrictions described in this Prospectus,  an Owner can transfer all
or part of the Accumulated Value among the Contract's  investment  options prior
to the Retirement Date. Transfers from one Division to another or into the Fixed
Account can be made by the Owner on an  unscheduled or scheduled  basis.  Owners
may transfer  limited  amounts once each Contract Year from the Fixed Account to
the Separate Account or may elect to make scheduled monthly transfers.

Total or Partial Surrenders

All or part of the  Accumulated  Value of a Contract may be  surrendered  by the
Owner prior to the  Retirement  Date.  Amounts  surrendered  may be subject to a
Surrender  Charge and total  surrenders  will be subject to the Annual  Fee,  if
applicable. The Surrender Charge does not apply to certain withdrawals including
the  withdrawal  during any Contract Year of an amount not to exceed the greater
of the  earnings  in the  Contract  or 10% of the  Purchase  Payments  otherwise
subject to the Surrender Charge. See "Total and Partial Surrenders,"  "Surrender
Charge"  and  "Annual  Fee."  Particular  attention  should  be  paid to the tax
implications  of any  surrender,  including  possible  penalties  for  premature
distributions. See "Federal Tax Matters."

Charges and Deductions

 The Company  deducts  daily charges at a rate of 1.25% per year of the value of
the average net assets of the  Separate  Account for the  mortality  and expense
risks it assumes. The Company has reserved the right to assess a daily charge at
a rate of .15% per year of the value of the average  net assets in the  Separate
Account to cover certain  administrative  expenses.  See  "Mortality and Expense
Risks Charge" and "Administrative Expense Charge."

To permit investment of the entire Purchase Payment, the Company does not deduct
sales charges at the time of investment.  However, a Surrender Charge is imposed
on certain total or partial  surrenders of the Contract to help defray  expenses
relating  to the  sale of the  Contract,  including  commissions  to  registered
representatives  and  other  promotional   expenses.   Certain  amounts  may  be
surrendered  without the  imposition of any  Surrender  Charge.  See  "Surrender
Charge."

There is also an Annual Fee for Contract  administration  and maintenance.  This
charge is the lesser of $30 or 2% of the Owner's  Accumulated  Value (subject to
any applicable  state law  limitations)  and is deducted on each Anniversary and
upon total  surrender of the  Contract.  This charge is not deducted  during the
Benefit Option period. The Company currently waives the Annual Fee for Contracts
that have an Accumulated  Value on the last day of the Contract Year of at least
$30,000.

Certain  states  and  other  jurisdictions   impose  premium  taxes  or  similar
assessments upon the Company,  either at the time Purchase  Payments are made or
when the Accumulated Value is surrendered or applied under a Benefit Option. The
Company  reserves  the  right to  deduct an amount  from  Purchase  Payments  or
Accumulated Value to cover such taxes or assessments, if any, when applicable.

Benefit Option Payments

     The Contract  provides  several types of fixed payment  Benefit  Options to
Annuitants or their  Beneficiaries.  The Owner has  considerable  flexibility in
choosing the Retirement  Date.  However,  the tax  implications of distributions
must be  carefully  considered,  including  the  possibility  of  penalties  for
commencing  benefits  either too soon or too late.  See  "Benefit  Options"  and
"Federal Tax Matters."

Death Benefit

In the event that the Annuitant or Owner dies prior to the  Retirement  Date, an
enhanced death benefit is payable to the Beneficiary of the Contract.  The death
benefit  may be paid as  either a single  sum cash  benefit  or under a  Benefit
Option.  See "Benefit  Payable on Death of Annuitant or Owner." In the event the
Annuitant dies on or after the Retirement  Date,  the  Beneficiary  will receive
only any  continuing  payments  which may be provided  by the Benefit  Option in
effect.

Right to Examine the Contract

The Owner has a right to examine the Contract. The Owner can cancel the Contract
by delivering or mailing it, together with a written  request,  to the Company's
home office or to the sales representative through whom it was purchased, before
the close of  business  on the  tenth day (or such  later  date as  provided  by
applicable state law) after receipt of the Contract.  If these items are sent by
mail, properly addressed and postage prepaid, they will be deemed to be received
by the  Company on the date  postmarked.  The  Company  will  return  either all
Purchase  Payments made,  without interest or  appreciation,  or the Accumulated
Value of the Contract, whichever is required by applicable state law.

Tax Implications

The tax  implications  for Owners,  Annuitants  and  Beneficiaries  can be quite
important.  A brief  discussion  of some of these is set out under  "Federal Tax
Matters"  in  this  Prospectus,   but  such  discussion  is  not  comprehensive.
Therefore,  an Owner  should  consider  these  matters  carefully  and consult a
qualified tax advisor before making Purchase Payments or taking any other action
in  connection  with the  Contract.  Failure  to do so could  result in  serious
adverse tax consequences which might otherwise have been avoided.

Questions and Other Communications

Any question  about  procedures  or the  Contract  should be directed to a sales
representative,  or the Company's home office:  Variable Annuity,  The Principal
Financial Group,  P.O. Box 9382, Des Moines,  Iowa  50306-9382;  1-800-247-9988.
Purchase Payments and written requests should be mailed or delivered to the same
home office address. All communications  should include the Contract number, the
Owner's name and, if different, the Annuitant's name.

Any  Purchase  Payment  or other  communication,  except a  cancellation  notice
described above under "Right to Examine the Contract," is deemed received at the
Company's  home office on the actual date of receipt there in proper form unless
received (1) after the close of regular  trading on the New York Stock Exchange,
or (2) on a date that is not a Valuation Date. In either of these two cases, the
date of receipt will be deemed to be the next Valuation Date.

Total or Partial Surrenders

     An Owner may  withdraw  cash  from the  Contract  at any time  prior to the
Retirement  Date  subject to any  charges  that may be  applied.  See "Total and
Partial  Surrenders."  Note that  withdrawals  before age 59 1/2 may  involve an
income tax penalty. See "Federal Tax Matters."

DESCRIPTION OF PRINCIPAL MUTUAL LIFE INSURANCE COMPANY (The "Company")

Principal Mutual Life Insurance  Company is a mutual life insurance company with
its home  office at The  Principal  Financial  Group,  Des  Moines,  Iowa 50306,
telephone number 515-247-5111.  It was originally incorporated under the laws of
the  State of Iowa in 1879 as  Bankers  Life  Association,  changed  its name to
Bankers  Life  Company in 1911 and  changed  its name to  Principal  Mutual Life
Insurance  Company in 1986. It is a member of The Principal  Financial  Group, a
diversified family of insurance and financial services corporations.

The Board of Directors of the Company has approved a Plan of Reorganization (the
"Plan")  pursuant to which the  Company  will adopt a mutual  insurance  holding
company structure.  The Plan was approved by the owners of annuity contracts and
life  insurance  policies  issued by the Company and has been  submitted  to the
Commissioner  of  Insurance of the State of Iowa (the "Iowa  Commissioner")  for
approval.

Under the Plan, the Company will form a mutual  insurance  holding company named
"Principal  Mutual  Holding  Company" and will convert to a stock life insurance
company.  As part of such  conversion,  the  Company  will  change  its  name to
"Principal Life Insurance Company" ("Principal Life").  Principal Mutual Holding
Company will be the ultimate  parent company in the family of companies known as
the Principal Financial Group(R).

Because the Company currently is a mutual life insurance  company,  Owners have,
in addition to  contract  rights  related to the  Contract,  certain  membership
interests in the  Company,  consisting  principally  of the right to vote on the
election  of  directors  of the  Company  and on other  matters and the right to
receive  distributions of the Company's  surplus upon liquidation or dissolution
of the Company.  The Plan will preserve but separate these  contract  rights and
membership  interests.  Contract  rights will remain with  Principal  Life,  and
Owners  on the date the Plan  becomes  effective  (the  "Effective  Date")  will
automatically  become  members of  Principal  Mutual  Holding  Company  and such
Owner's  membership  interests  in the Company will be  extinguished.  Under the
terms of the Plan,  the  membership  interests  of members of  Principal  Mutual
Holding Company will consist principally of the right to vote on the election of
directors  of  Principal  Mutual  Holding  Company  and on other  matters and to
receive   distributions  of  Principal  Mutual  Holding  Company's  assets  upon
liquidation  or  dissolution  of Principal  Mutual  Holding  Company.  Owners of
Contracts   issued  by  Principal  Life  after  the  Effective  Date  also  will
automatically  become members of Principal Mutual Holding Company. The Plan will
not, in any way, increase premium payments or reduce Contract benefits,  values,
guarantees or other Contract  obligations owed to Owners.  Contract  obligations
will be the responsibility of Principal Life.

The  Company  believes  that  adoption  of the Plan will  result in a  corporate
structure that, among other things, will provide the Company with flexibility in
raising capital  through  various means that are not currently  available to it,
including stock offerings. Any initial offering of voting stock to third parties
will be subject to the approval of the Iowa Commissioner.  Although there are no
current plans to offer voting stock, in the event voting stock was sold to third
parties,  it is possible that the interests of such third party shareholders and
Owners could diverge on certain issues. The Company, however, believes that such
shareholders  and Owners will generally have a greater  commonality of interests
than the potential for conflict and will endeavor to minimize the  occurrence of
such  conflicts  and to  operate  the  companies  in the best  interests  of all
constituencies.

The Effective  Date is scheduled to be July 1, 1998,  but the Iowa  Commissioner
must first approve the Plan. In addition,  insurance  regulatory  authorities in
each state must issue an amendment to the Company's Certificate of Authority (to
reflect  the name  change  from  Principal  Mutual  Life  Insurance  Company  to
Principal Life  Insurance  Company) and must approve the forms which support the
Contract.  Should  the  Effective  Date be other  than July 1, 1998 or if states
other than Iowa have not completed  action by that date, the Company will notify
existing Owners and others by supplementing this prospectus. Contracts issued on
or after  the  Effective  Date will be issued  by  Principal  Life,  will not be
participating  and will not be eligible to  participate in any  distribution  of
divisible  surplus  (see  "Surplus   Distribution  at  Sole  Discretion  of  the
Company"). As Owner of a Contract issued after the Effective Date, you will be a
member of Principal Mutual Holding Company as described above.

Principal  Mutual Life Insurance  Company is authorized to do business in the 50
states of the United  States,  the District of  Columbia,  the  Commonwealth  of
Puerto Rico, and the Canadian Provinces of Alberta, British Columbia,  Manitoba,
Ontario and Quebec. The Company offers a full range of products and services for
businesses, groups and individuals including individual insurance, pension plans
and group/employee  benefits. The Company has ranked in the upper one percent of
life  insurers  in assets  and  premium  income  and has  consistently  received
excellent  ratings  from  the  major  rating  firms  based  upon  the  Company's
claims-paying  ability. The Company has $63.2 billion in assets under management
and serves more than 9.7 million individuals and their families.

PRINCIPAL MUTUAL LIFE INSURANCE COMPANY SEPARATE ACCOUNT B

Separate  Account B was established on January 12, 1970 pursuant to a resolution
(as  amended)  of the  Executive  Committee  of the  Board of  Directors  of the
Company.  Under Iowa insurance laws and regulations the income, gains or losses,
whether  or not  realized,  of  Separate  Account B are  credited  to or charged
against the assets of  Separate  Account B without  regard to the other  income,
gains or losses of the Company.  Although the assets of Separate Account B equal
to the reserves and liabilities  arising under the contracts  issued  thereunder
will not be  charged  with any  liabilities  arising  out of any other  business
conducted  by the  Company,  the  reverse is not true.  Hence,  all  obligations
arising  under the Contract,  including  the promise to make payments  under the
Benefit Options, are general corporate obligations of the Company.

Separate  Account B was  registered  on July 17,  1970 with the  Securities  and
Exchange  Commission as a unit investment trust under the Investment Company Act
of 1940,  as amended.  Such  registration  does not involve  supervision  by the
Commission of the investments or investment policies of Separate Account B.

The Company is taxed as an insurance  company  under the Internal  Revenue Code.
The  operations  of Separate  Account B are part of the total  operations of the
Company  but are treated  separately  for  accounting  and  financial  statement
purposes and are considered separately in computing the Company's tax liability.
Separate  Account B is not affected by federal  income taxes paid by the Company
with respect to its other operations, and under existing federal income tax law,
investment  income and capital gains  attributable to Separate Account B are not
taxed.  The Company reserves the right to charge Separate Account B with, and to
create a reserve for, any tax liability which the Company  determines may result
from maintenance of Separate Account B. To the best of the Company's  knowledge,
there is no current prospect of any such liability.

There are  currently  nineteen  Divisions  in Separate  Account B. The assets of
Divisions are invested  exclusively in shares of a corresponding  Account of the
Principal  Variable  Contracts  Fund,  Inc. New  Divisions may be added and made
available to Owners of the Contract.  Divisions may also be eliminated  from the
Separate  Account.  Some of these  Accounts  also offer their shares to variable
life  separate  accounts of  the  Company and  to variable  annuity and variable
life separate accounts of unaffiliated insurance companies.

MUTUAL FUNDS

The Divisions of Separate Account B currently invest exclusively in shares of an
Account of the Fund.  The eighteen  Accounts  available  for  investment  are as
follows:  Aggressive Growth,  Asset Allocation,  Balanced,  Bond, Capital Value,
Government Securities, Growth, International,  International SmallCap, MicroCap,
MidCap,  MidCap Growth,  Money Market, Real Estate,  SmallCap,  SmallCap Growth,
SmallCap  Value and Utilities.  Not all Accounts are available in all states.  A
current list of which  Accounts are available in your state may be obtained from
an authorized agent of the Company.  A full  description of the Accounts,  their
investment  policies and  restrictions,  their charges,  the risks  attendant to
investing in them,  and other  aspects of their  operations  is contained in the
Prospectus  for the Fund  accompanying  this  Prospectus and in the Statement of
Additional  Information for the Fund referred to therein.  Additional  copies of
these  documents  may be  obtained  from a  sales  representative  or  from  the
Company's home office.

The  Principal  Variable  Contracts  Fund,  Inc.  is  a  diversified,   open-end
investment management company, typically known as a Mutual Fund. The Manager for
the Fund is Principal Management  Corporation.  Some of the Accounts of the Fund
are also used to fund variable life insurance  contracts  issued by the Company.
The Fund's  Board of  Directors  will  monitor  events in order to identify  any
material irreconcilable  conflicts between the interests of the variable annuity
contract  owners  and  life  insurance  policyowners  that  may  develop  and to
determine  what  action,  if any,  should be taken in  response  thereto.  If it
becomes necessary for any separate account to replace shares of any Account with
another  investment,   the  Account  may  have  to  liquidate  securities  on  a
disadvantageous  basis. See "Eligible  Purchasers and Purchase of Shares" in the
Fund prospectus for a discussion of the potential  risks  associated with "mixed
funding."

The  Company  purchases  and redeems  shares of the  Accounts  for the  Separate
Account  at their  net  asset  value  without  the  imposition  of any  sales or
redemption  charges.  Such shares represent  interests in the Accounts available
for investment by the Separate Account.  Each Account  corresponds to one of the
Divisions of the Separate Account.  The assets of each Account are separate from
the  others  and each  Account's  performance  has no effect  on the  investment
performance of any other Account.

Any  dividend or capital  gain  distributions  attributable  to the Contract are
automatically  reinvested  in shares of the Account from which they are received
at that  Account's  net  asset  value  on the  date  paid.  Such  dividends  and
distributions will have the effect of reducing the net asset value of each share
of the corresponding Account and increasing,  by an equivalent value, the number
of shares  outstanding of that Account.  However,  the value of the interests of
Owners in the  corresponding  Division  will not  change as a result of any such
dividends and distributions.

SURPLUS DISTRIBUTION AT SOLE DISCRETION OF THE COMPANY

It is not anticipated  that any divisible  surplus will ever be distributable to
these  Contracts in the future  because the Contracts are not expected to result
in a  contribution  to the  divisible  surplus of the Company.  However,  if any
distribution of divisible surplus is made, it will be made to Owners in the form
of cash.

THE CONTRACT

The Contract  described in this  Prospectus  is designed to provide  individuals
with retirement  benefits in connection with (1) Individual  Retirement  Annuity
plans or programs ("IRA Plans"),  Roth IRA Plans,  Simplified  Employee  Pension
Plans  ("SEPs")  and  Salary   Reduction   Simplified   Employee  Pension  Plans
("SAR/SEPs")  and Savings  Incentive  Match Plan for Employees  ("SIMPLE")  IRAs
adopted   pursuant  to  Section  408  of  the  Internal  Revenue  Code  and  (2)
non-qualified  retirement  plans. The Contract  provides for the accumulation of
values on a fixed and variable basis and the payment of annuity  benefits in the
form of Benefit Options on a fixed basis.

A.   Purchasing a Contract

     Persons  wishing to purchase a Contract  must complete an  application  and
     make an initial Purchase  Payment.  Receipt of the Initial Purchase Payment
     at the time of  application  is not required in connection  with SEPs.  The
     application  is  forwarded  to the Company for  processing.  Acceptance  is
     subject to underwriting and suitability  rules and procedures.  The Company
     reserves the right to reject any application or any Purchase Payment if, in
     the view of the Company,  the Company's  underwriting and suitability rules
     and procedures are not satisfied.

     Purchase  Payments  which are  remitted  through an employer  for  multiple
     employee-Owner/Annuitants   must  also  be   accompanied   by   information
     identifying the proper  Contracts and accounts to be credited with Purchase
     Payments.

     If the  application  can be  accepted  in the form  received,  the  initial
     Purchase  Payment  will be credited  within two  Valuation  Dates after the
     later of receipt of the  application  or  receipt of the  initial  Purchase
     Payment at the  Company's  home  office.  If the initial  Purchase  Payment
     cannot be credited  within five Valuation  Dates after receipt  because the
     application  or other  issuing  requirements  are  incomplete,  the initial
     Purchase  Payment  will be returned  unless the  applicant  consents to our
     retaining  the  initial  Purchase  Payment  and  crediting  it  within  two
     Valuation Dates after the necessary requirements are fulfilled.

     The date that the  Contract is issued is the  Contract  Date.  The Contract
     Date is the date used to determine  Contract Years,  regardless of when the
     Contract is  delivered.  The  crediting  of  investment  experience  in the
     Separate Account, or a fixed rate of return in the Fixed Account, begins as
     of the Contract Date,  even if that date is delayed due to  underwriting or
     administrative requirements.

     Generally,  additional Purchase Payments will be accepted at any time after
     the  Contract  Date  and  prior  to the  Retirement  Date,  as  long as the
     Annuitant  is  living.   Purchase  Payments  (together  with  any  required
     information  identifying  the proper  Contracts and accounts to be credited
     with Purchase  Payments)  must be delivered to the  Company's  home office.
     Additional  Purchase Payments are credited to the Contract and added to the
     Accumulated  Value as of the end of the Valuation  Period in which they are
     received.

     1.  Purchase Payment Limitations

         For Contracts issued in connection with non-qualified retirement Plans,
         the  initial  Purchase  Payment  must be at least  $2,500.  The initial
         Purchase  Payment for all other Contracts must be at least $1,000.  The
         minimum  subsequent  investment  is $100.  A $100  monthly  minimum for
         initial and subsequent  investments is available for Contracts to which
         Purchase  Payments are made on a monthly  basis through an account of a
         bank or similar  financial  institution  under an Automatic  Investment
         Program.  Forms and  preauthorized  check  agreements  to  establish an
         Automatic  Investment  Program are  available  from  Princor  Financial
         Services Corporation. For Contracts which are issued in connection with
         a  retirement  plan  covering  more than four  people,  the initial and
         subsequent  monthly  Purchase  Payments under each Contract must at all
         times  average  at least  $100  and in no case be less  than  $50.  The
         Company  reserves  the right to increase  the  minimum  amount for each
         Purchase  Payment to not more than  $1,000.  The Company  reserves  the
         right to terminate a Contract and  distribute  the  Accumulated  Value,
         less  any  applicable  charges,  if no  premiums  are paid  during  two
         consecutive  calendar years and the Accumulated Value or total Purchase
         Payments less partial  surrenders and applicable  surrender  charges is
         less than  $2,000.  The Company  will notify the Owner of its intent to
         exercise  this right and  provide the Owner a 60 day period to increase
         the Accumulated Value to $2,000.

         The total of all Purchase  Payments may not exceed  $2,000,000  without
         the Company's prior approval.  In New Jersey,  after the first Contract
         Year,  the total of Purchase  Payments  made during a Contract Year may
         not exceed $100,000.

     2.  Allocation of Purchase Payments

         The initial Purchase Payment is allocated, as specified by the Owner in
         the  Contract  application,  among one or more of the  Divisions of the
         Separate  Account,  or to the  Fixed  Account,  or to both.  Subsequent
         Purchase  Payments  are  allocated  in the same  way,  or  pursuant  to
         different  allocation  percentages  that  the  Owner  may  subsequently
         specify.  Allocations to the Fixed Account are not allowed if the Fixed
         Account Value  immediately  after the  allocation  exceeds  $1,000,000,
         except with our prior approval.

         Some states require the Company to return the initial  Purchase Payment
         to an Owner who  reconsiders  the  decision  to purchase  the  Contract
         within a certain  time  period.  See "Right to Examine  the  Contract."
         Initial Purchase Payments for a Contract issued in one of the states in
         the following table are allocated to the Money Market Division until 15
         days (20 days for  Contracts  issued in the  State of Idaho)  after the
         Contract Date at which time they are reallocated in accordance with the
         Owner's allocation instructions.

     States in Which Purchase Payments are Returned

       Colorado            Kentucky         North Carolina
       Connecticut*        Louisiana        Oklahoma
       Georgia             Maryland         Rhode Island
       Hawaii              Michigan         South Carolina
       Idaho               Missouri         Utah
       Indiana             Nebraska         Washington

   * Purchase  Payments are  refunded if the Contract is cancelled  prior to its
delivery, otherwise the account value is refunded.

   3.  Right to Examine the Contract

       Under  state law,  the Owner has the right to examine the  Contract.  The
       right is often  referred  to as a "free  look"  period.  The "free  look"
       period is 10 days after the date the  contract is  delivered to the Owner
       in all states except as follows:

       a. Contracts issued in California to Owners age 60 and over have a 30 day
       "free look" period;  b. Contracts  issued in Colorado have a 15 day "free
       look" period; and c. Contracts issued in Idaho and North Dakota have a 20
       day "free look" period.

       The Owner can cancel the Contract by delivering  or mailing it,  together
       with a written  request,  to the  Company's  home  office or to the sales
       representative  through  whom  it was  purchased,  before  the  close  of
       business  on the last day of the "free look"  period.  If these items are
       sent by mail, properly addressed and postage prepaid, they will be deemed
       to be received by the Company on the date  postmarked  for the purpose of
       determining  whether the "free look" period has elapsed.  If the Purchase
       Payments are  allocated to the Money Market  Division as described  above
       under  "Allocation  of Purchase  Payments,"  the Company  will return the
       greater of the Contract's value or Purchase Payments paid if the Contract
       is cancelled. Otherwise, the Company will return the Accumulated Value of
       the Contract.

   4.  Exchange Credit

       Owners of Single Premium Deferred  Annuities  ("SPDA") and Single Premium
       Deferred  Annuity Plus  ("SPDA+")  contracts that have been issued by the
       Company and are within at least eight months of the eighth  Contract Year
       may transfer the  accumulated  value,  free of surrender  charge,  to the
       Contract described in this Prospectus.  In addition, the Company will add
       an amount as an Exchange  Credit.  Currently,  the amount of the Exchange
       Credit is one  percent  (1%) of the SPDA or SPDA+  surrender  value.  The
       amount of the Exchange Credit is subject to change.  The Company reserves
       the right to terminate this Exchange Credit program.

       In making  the  decision  as to whether  to make an  exchange,  the Owner
       should  carefully review the SPDA contract or the SPDA+ contract and this
       Prospectus as the charges and provisions of the contracts  differ. If the
       existing  SPDA or SPDA+  contract  is  currently  eligible  for waiver of
       Surrender  Charge  due  to  critical  need,  similar  riders  may  not be
       available under this Contract.

       To initiate an exchange,  the Company must receive 1) an application for 
       the Contract;  2) a surrender form for the existing SPDA/SPDA+ contract; 
       3) a  replacement  form  (based  on  state  written)  and 4) an  Annuity 
       Exchange  Request and Release Form.  The exchange will become  effective 
       upon receipt of  completed  items  listed  above and  acceptance  of the 
       application.  The transaction will be valued at the end of the Valuation 
       Period in which the Company receives all the necessary  documentation at 
       its home office.

       The  Exchange  Credit is  allocated  among the  Divisions of the Separate
       Account  or to the  Fixed  Account,  or both,  in the  same  ratio as the
       Purchase  Payment.  The credit is treated as additional income for income
       tax  purposes.  If the Owner  exercises  the right to return the Contract
       during the "free  look"  period,  the amount  returned  is reduced by any
       credit applied. See "Right to Examine the Contract".

B.   Prior to the Retirement Date

   1.  Determining the Accumulated Value of the Contract

       The Owner's  Accumulated Value is the total of any Separate Account Value
       plus any Fixed Account Value under the Contract.  For a discussion of how
       Fixed Account Value is calculated, see "Fixed Account."

       There is no  guaranteed  minimum  Separate  Account  Value.  The Separate
       Account  Value  will  reflect  the  investment  experience  of the chosen
       Divisions  of the  Separate  Account,  all Purchase  Payments  made,  any
       partial  surrenders,  and all  charges  assessed in  connection  with the
       Contract.  Therefore,  the Separate  Account Value changes from Valuation
       Period to Valuation Period. To the extent  Accumulated Value is allocated
       to the Separate Account, the Owner bears the entire investment risk.

       A Contract's  Separate  Account Value is based on Unit Values,  which are
       determined on each Valuation  Date. The value of a Unit for a Division on
       any Valuation Date is equal to the previous value of that Division's Unit
       multiplied by that Division's Net Investment Factor  (discussed  directly
       below)  for the  Valuation  Period  ending on that  Valuation  Date.  Net
       Purchase  Payments  applied to a given  Division will be used to purchase
       Units at the Unit Value of that Division next determined after receipt of
       a Purchase Payment. See "Allocation of Purchase Payments and Transfers."

       At the end of any Valuation  Period, a Contract's  Separate Account Value
in a Division is equal to:

       o The number of Units in the Division; times

       o The value of one Unit for that Division.

       The number of Units in each Division is equal to:

       o The initial Units purchased on the Contract Date; plus

       o Units purchased at the time that additional  Purchase Payments are
         allocated to the Division; plus

       o Units purchased through transfers from another Division or from the 
         Fixed Account; less

       o Units redeemed to pay for the portion of any partial surrenders 
         allocated to the Division; less

       o Units redeemed as part of a transfer to another Division or to the 
         Fixed Account; less

       o Units redeemed to pay charges under the Contract.

     Net  Investment  Factor.  Each Net  Investment  Factor is the  quantitative
     measure of the investment  performance of each Division of Separate Account
     B. For any  specified  Valuation  Period  the Net  Investment  Factor for a
     Division for a Contract is equal to

       (a) the quotient  obtained by dividing (i) the net asset value of a share
           of the underlying Account as of the end of the Valuation Period, plus
           the per share  amount of any dividend or other  distribution  made by
           the Account  during the  Valuation  Period  (less an  adjustment  for
           taxes,  if any) by (ii) the net asset value of a share of the Account
           as of the end of the immediately preceding Valuation Period,

                   reduced by

       (b) a mortality  and expense  risks charge in an amount equal to a simple
           interest  rate for the  number of days  within the  Valuation  Period
           equivalent  to an annual rate of 1.25%.  The Company has reserved the
           right to assess a daily  administrative  expense  charge at an annual
           rate of up to .15% of the value of the average  Separate  Account net
           assets.  If and to the extent such a charge is assessed,  such charge
           will be included in the  calculation of the Net Investment  Factor in
           the same manner as the mortality and expense risks charge.

       The amount of any taxes referred to in subparagraph  (a) above (currently
       none)  and the  amounts  derived  from  applying  the rate  specified  in
       subparagraph (b) above will be accrued daily and will be transferred from
       Separate Account B at the discretion of the Company.

   2.  Allocation of Purchase Payments

       Allocation of Purchase Payments.  In the application for a Contract,  the
       Owner  can  allocate  Purchase  Payments,  or  portions  thereof,  to the
       available  Divisions of the Separate Account or to the Fixed Account,  or
       both.  Percentages must be in whole numbers and the total allocation must
       equal 100%. The percentage  allocations for future Purchase  Payments may
       be changed,  without charge,  at any time by sending a written request to
       the Company's home office or by telephone as described below.  Changes in
       the allocation of future  Purchase  Payments will be effective at the end
       of the  Valuation  Period  in which  the  Company  receives  the  Owner's
       request.

   3.  Transfers

       Unscheduled  Transfers.  Transfers of amounts from one available Division
       of the Separate  Account to another or into the Fixed Account can be made
       by the Owner.  A transfer from a Division of the Separate  Account to the
       Fixed  Account may not be made if a transfer  from the Fixed Account to a
       Division  of the  Separate  Account  has been made  within the  six-month
       period  prior  to the  date of the  requested  transfer  to the  Separate
       Account or if  immediately  after the  transfer to the Fixed  Account the
       Owner's  Fixed  Account  Value  exceeds  $1  million.  The  amount  to be
       transferred  may be stated as a dollar  amount or as a percentage  of the
       Separate  Account  Value of the Division from which the transfer is to be
       made. The amount  transferred from each Division must equal or exceed the
       lesser of $100 or 100% of the Owner's interest in the Division. Transfers
       may be completed by sending a written  request to the Company at its home
       office, or by telephone as described below.

       All or  part  of the  values  in one or more  Divisions  of the  Separate
       Account may be transferred at one time.  Transfers from the Fixed Account
       are restricted on both amount and timing.  See "Fixed Account  Transfers,
       Total and Partial Surrenders."  Transfers from a Division of the Separate
       Account will be executed and values will be determined in connection with
       the transfers as of the end of the Valuation  Period in which the Company
       receives  the  transfer  request.  There is a $30  charge on  unscheduled
       transfers  after the twelfth such transfer  during a Contract  year.  For
       this  purpose,  all  transfers  between  and among the  Divisions  of the
       Separate  Account and the Fixed  Account will be treated as one transfer,
       if all the  transfer  requests  are made at the same  time as part of one
       request.   The  Company  also  reserves  the  right  to  reject  transfer
       instructions provided by a person providing them for multiple contracts.

       Scheduled  Transfers.  The owner may  elect to have  automatic  transfers
       completed on a periodic basis from any Division of the Separate  Account.
       Scheduled  transfers are  available  from a Division only if the value of
       the Separate Account Value in such Division equals or exceeds $5,000.  An
       Owner may establish  scheduled  transfers by sending a written request to
       the  Company  at its home  office or by  telephone  as  described  below.
       Scheduled   transfers   will  be  completed  on  a  monthly,   quarterly,
       semi-annual  or annual  basis on the date (other  than the 29th,  30th or
       31st)  specified by the Owner.  If the requested  date is not a Valuation
       Date, the transfer will be completed on the next valuation date following
       such specified date.  Scheduled  transfers of the dollar amount specified
       by the Owner (minimum of $100) will continue  until the Separate  Account
       Value in the Division from which such  transfers are made is exhausted or
       until the Owner notifies the Company to discontinue  such transfers.  The
       Company  reserves the right to limit the number of  Divisions  from which
       transfers  will  be  made  simultaneously,  but  in no  event  will  such
       limitation be less than two Divisions.

   4.  Automatic Portfolio Rebalancing

       Automatic  Portfolio  Rebalancing (APR) allows you to maintain a specific
       percentage  of your  contract  values in each account over time.  You may
       elect  APR at the time of  application  or after  the  Contract  has been
       issued.

       For  example,  a customer may elect APR and choose to rebalance so 50% of
       policy values are in the Capital Value  Division and 50% are in the Money
       Market Division.  At the end of the specified  period,  60% of the values
       may be invested in the Capital  Value  Division,  with the  remaining 40%
       invested in the Money Market  Division.  By  rebalancing,  units from the
       Capital Value  Division are redeemed and applied as purchase  payments to
       the Money Market  Division so 50% of the  contract  values are once again
       invested in each division.

       APR is not available for values in the Fixed  Account.  You may elect APR
       only if you have  not  arranged  for  scheduled  transfers  from the same
       divisions.

       APR  transfers  will not begin  until the  expiration  of the "free look"
       period (see "Right to Examine the Contract"). There will be no charge for
       APR  transfers.  These  transfers  will not be considered as  unscheduled
       transfers in determining any transfer fee.

       You may rebalance through APR quarterly, semi-annually, or annually based
       on a calendar year or contract year. In addition,  you may rebalance on a
       one-time basis by completing a form and submitting it to the Company home
       office or by calling  1-800-247-9988 (if telephone privileges apply). The
       transfers will be made at the end of the next Valuation  Period after the
       APR instruction is received by the Company.

   5.  Telephone Services

       Unless  telephone  transaction  services (where allowed by state law) are
       declined on the application for a Contract, or at any subsequent time the
       Owner  notifies  the Company in writing to remove  telephone  transaction
       services,  changes in the  allocation  of future  Purchase  Payments  and
       transfers may be made pursuant to telephone instructions,  subject to the
       above terms.  The telephone  transactions may be exercised by telephoning
       1-800-247-9988. Telephone transfer requests must be received by the close
       of the New York  Stock  Exchange  on a day when the  Company  is open for
       business to be effective that day.  Requests made after that time or on a
       day when the Company is not open for business  will be effective the next
       business day.  Although  neither the Separate  Account nor the Company is
       responsible for the authenticity of telephone transaction  requests,  the
       right is  reserved  to refuse to accept  telephone  requests  when in the
       opinion  of the  Company it seems  prudent to do so. The Owner  bears the
       risk of loss  caused by  fraudulent  telephone  instructions  the Company
       reasonably  believes to be genuine.  The Company  will employ  reasonable
       procedures  to assure  telephone  instructions  are  genuine  and if such
       procedures are not followed,  the Company may be liable for losses due to
       unauthorized  or  fraudulent   transactions.   Such  procedures   include
       recording all telephone instructions,  requesting personal identification
       information such as the caller's name,  daytime telephone number,  social
       security  number and/or  birthdate and sending a written  confirmation of
       the  transaction  to the  Owner's  address of  record.  Owners may obtain
       additional  information  and  assistance  by  telephoning  the toll  free
       number.  Telephone  instructions  received from any joint  contract owner
       will be  binding  on all  contract  owners.  The  Company  may  modify or
       terminate telephone transfer procedures at any time.

       You may obtain contract  information  from our Direct Dial system between
       7:00 am and 9:00 pm, Central time, Monday through Saturday.  Through this
       automated  telephone system, you can obtain information about unit values
       and contract values,  initiate  certain changes to your contract,  change
       your  Personal  Identification  Number  (PIN),  or  speak  directly  to a
       customer service representative.  The telephone number is 1-800-247-9988.
       As with other telephone  services,  instructions  received via our Direct
       Dial system will be binding on all contractowners.

   6.  Total and Partial Surrenders

       Total Surrenders. The Owner may surrender all of the cash surrender value
       at any time during the life of the Annuitant and prior to the  Retirement
       Date by a written request sent to the Company's home office.  The Company
       reserves  the right to  require  that the  Contract  be  returned  to the
       Company  prior to  making  payment,  although  this will not  affect  the
       determination of the amount of the cash surrender  value.  Cash surrender
       value is the Accumulated  Value at the end of the Valuation Period during
       which the  written  request  for the total  surrender  is received by the
       Company at its home office, less any applicable Surrender Charge,  Annual
       Fee  and  Transaction  Fee.  For  discussion  of  these  charges  and the
       circumstances  under  which they  apply,  see  "Annual  Fee,"  "Surrender
       Charge," and "Transaction Fee."

       The  written   consent  of  all  collateral   assignees  and  irrevocable
       beneficiaries  of a non-qualified  Contract must be obtained prior to any
       total  surrender.  Surrenders from the Separate Account will generally be
       paid  within  seven  days of the date of receipt  by the  Company's  home
       office of the written  request,  or such earlier date as required by law.
       Postponement of payments may occur,  however,  in certain  circumstances.
       See "Postponement of Payments."

       Since the Owner  assumes  the  investment  risk with  respect  to amounts
       allocated to the Separate  Account,  and because  certain  surrenders are
       subject to a Surrender  Charge,  the amount paid upon total  surrender of
       the  cash  surrender   value  (taking  into  account  any  prior  partial
       surrenders) may be more or less than the total Purchase Payments made.

       Unscheduled Partial Surrenders.  At any time prior to the Retirement Date
       and during the  lifetime  of the  Annuitant,  the Owner may  surrender  a
       portion of the Fixed Account  Value and/or the Separate  Account Value by
       sending a written  request to the  Company's  home  office.  The  minimum
       unscheduled partial surrender amount is $100 and the Accumulated Value of
       the  Contract  must be  $5,000  or more  immediately  after  the  partial
       surrender.  The Company reserves the right to increase the minimum $5,000
       remaining Accumulated Value but in no event will it exceed $10,000.

       In order for a request to be processed, the Owner must specify the dollar
       amount of the Accumulated Value to surrender. The amount surrendered will
       be deducted from the Owner's  Fixed  Account  Value and/or  interest in a
       Division according to the surrender  allocation  percentages  provided by
       the Owner.  Percentages  may be either zero or any whole  number and must
       total 100%.

       The Company will surrender Units from the Separate  Account and/or dollar
       amounts  from the Fixed  Account so that the total  amount of the partial
       surrender equals the dollar amount of the partial  surrender request plus
       any applicable  Surrender Charge. The partial surrender will be effective
       at the end of the  Valuation  Period in which the  Company  receives  the
       written request for partial  surrender at its home office.  Payments will
       generally be made within seven days of the effective date of such request
       or such  earlier  date as required by law,  although  certain  delays are
       permitted. See "Postponement of Payments."

       Scheduled  Partial  Surrenders.  The  owner  may  elect  to have  partial
       surrenders  completed  on a  periodic  basis  from  any  Division  of the
       Separate  Account  and/or Fixed  Account.  Scheduled  partial  surrenders
       (sometimes  referred to as a "Flexible  Withdrawal Option") are available
       only if the value of the Accumulated Value is at least $5,000 at the time
       the surrenders begin.  Scheduled partial surrenders may be established by
       the Owner by  providing  written  notice to the Company at the  Company's
       home office.  The Owner may specify  monthly,  quarterly,  semi-annual or
       annual  partial  surrenders  to be completed on any date other than 29th,
       30th or 31st. If the specified date is not a Valuation  Date,  surrenders
       will be completed on the next  Valuation  Date  following  such specified
       date.  Partial  surrenders will continue until the  Accumulated  Value is
       exhausted  or until the Owner  notifies  the Company to  discontinue  the
       scheduled surrenders.

       The Internal  Revenue Code provides that a penalty tax will be imposed on
       certain  premature  surrenders.  For a  discussion  of this and other tax
       implications  of total  and  partial  surrenders,  including  withholding
       requirements, see "Federal Tax Matters."

   7.  Benefit Payable on Death of Annuitant or Owner

       The death benefit paid to the deceased's  Beneficiary will be the greater
       of the standard death benefit or the annual  enhanced  death benefit,  if
       elected.

       a.  Standard Death Benefit

           If the Annuitant or Owner dies prior to the Retirement  Date, a death
           benefit will be paid to the deceased's Beneficiary. The amount of the
           death benefit will be the greater of:

           (1) the  Accumulated  Value on the date the Company  receives  Notice
               (including proof) of death; or

           (2)  total  Purchase  Payments  less  any  partial   surrenders  (and
                Surrender  Charges incurred) as of the date the Company receives
                Notice (including proof) of death; or

           (3)  Highest  Accumulated  Value  on any  prior  Anniversary  that is
                divisible  equally by seven, plus any Purchase Payments and less
                any partial  surrenders  (and Surrender  Charges  incurred) made
                after that Anniversary.

       b.  Annual Enhanced Death Benefit

           Definition  The Company also offers an optional  death  benefit,  the
           Annual  Enhanced  Death  Benefit  Rider.  Under  this  rider,  if the
           original  annuitant  or original  owner dies prior to the  Retirement
           date, the death benefit payable to the deceased's  Beneficiary is the
           greater of:

           (1)  The Standard Death Benefit (described above); or

           (2)  An annual  increasing death benefit,  based on Purchase Payments
                (accumulated  at 5%) less any partial  surrenders  and Surrender
                Charges  incurred  (accumulated at 5%) until the later of either
                the  Contract  Anniversary  following  the  original  Owner's or
                original  Annuitant's  age 75  birthday  or five  years from the
                effective date of the rider; or

           (3)  The  highest   Accumulated  Value  on  a  Contract   Anniversary
                (increased  for subsequent  Purchase  Payments and decreased for
                partial  surrenders and Surrender  Charges  incurred)  until the
                later of the Contract Anniversary following the original Owner's
                or original  Annuitant's  age 75 birthday or five years from the
                effective date of the rider.

           Lock-In  Feature At the later of the Contract  Anniversary  following
           the original Owner's or original  Annuitant's age 75 birthday or five
           years after issue ("Lock-In Date"), the Annual Enhanced Death Benefit
           amount will be locked-in and will only increase by Purchase  Payments
           made  since  the  Lock-In  Date,  less  any  partial  surrenders  and
           Surrender  Charges  incurred since the Lock-In Date. The Lock-In will
           not prevent the death  benefit  from  increasing  further as provided
           under the Standard Death Benefit provision in your Contract.

           Rider  charges will  continue to be deducted on a quarterly  basis to
           keep the Annual Enhanced Death Benefit locked in.

           After the Lock-In Date,  once the Standard  Death Benefit  equals the
           Annual Enhanced Death Benefit, this Rider will terminate. You will be
           charged  for the Annual  Enhanced  Death  Benefit  Rider based on the
           number of days from the  beginning of the calendar  quarter until the
           Rider is terminated.

           Charges  The current  charge for the Annual  Enhanced  Death  Benefit
           Rider  is  deducted   through  the  redemption  of  units  from  your
           Contract's Accumulated Value at the end of each calendar quarter. The
           redemption  of units from the  Owner's  Fixed  Account  value  and/or
           interest in a Division will be made in the same ratio as each Account
           bears to the Owner's Accumulated Value.
   
           Once  terminated,  this Rider cannot be reinstated.  (In Florida this
           Rider may be reinstated  upon proof  acceptable to the Company of the
           good health of original Owner or original Annuitant.  This proof must
           be sent to Company's home office.)
    
       c.  Payment of Death Benefit

           The death benefit  generally will be paid within seven days after the
           Company  receives  Notice  (including  proof)  of death  and  written
           instructions as to the manner of payment to the Beneficiary,  or such
           earlier date as required by law. Under certain circumstances, payment
           of  the  death  benefit  may  be  postponed.   See  "Postponement  of
           Payments."  The  death  benefit  will be paid  according  to  benefit
           instructions  provided by the deceased.  If benefit instructions have
           not been  provided  the death  benefit will be paid upon receipt of a
           written request for settlement  method. The Company will pay interest
           (at an annual  rate  equal to or  greater  than 3% or such other rate
           required by state law) on the death benefit from the date it receives
           proof of death (or such other date  required  by state law) until the
           date of payment or until the date the death  benefit is applied under
           a Benefit Option.

           If the Owner dies before the Annuitant and the Owner's Beneficiary is
           the surviving spouse, the Company will continue the Contract with the
           spouse as the new Owner unless the spouse elects to receive the death
           benefit.  If  benefit  instructions  have  not  been  provided,   the
           Beneficiary  may (a) receive a single sum payment,  which  terminates
           the  Contract,  or (b) select a Benefit  Option.  If the  beneficiary
           selects a Benefit  Option,  he or she will  have all the  rights  and
           privileges  of an Annuitant  under the Contract.  If the  Beneficiary
           desires a Benefit Option,  the election should be made within 60 days
           of the date the death  benefit  becomes  payable.  Failure  to make a
           timely election can result in unfavorable tax consequences.
           For further information, see "Federal Tax Matters."

           We accept any of the following as proof of death: a certified copy of
           a death  certificate;  a copy of a  certified  decree  of a court  of
           competent  jurisdiction  as  to  the  finding  of  death;  a  written
           statement  by a medical  doctor who attended the deceased at the time
           of death; or any other proof satisfactory to us.

           If the Owner dies before the Annuitant and before the Retirement Date
           with respect to a Contract not issued in connection  with  retirement
           plans  qualified  under  Section 408 of the  Internal  Revenue  Code,
           certain additional  requirements are mandated by the Internal Revenue
           Code,   which  are  discussed  under  "Required   Distributions   for
           Non-Qualified Contracts." It is imperative that written notice of the
           death of the Owner be promptly transmitted to the Company at its home
           office,  so that  arrangements  can be made for  distribution  of the
           entire  interest in the Contract to the  Beneficiary in a manner that
           satisfies the Internal Revenue Code requirements.  Failure to satisfy
           these requirements may result in the Contract not being treated as an
           annuity for federal income tax purposes, which could have adverse tax
           consequences.

C.   After the Retirement Date

   1.  Retirement Date

       The  Owner  may  specify  a  Retirement  Date  in  the  application.  The
       Retirement  Date  marks  the  beginning  of the  period  during  which an
       Annuitant  receives  Benefit  Option  payments  under the  Contract.  The
       Company may not permit a  Retirement  Date which is on or after the later
       of the  Annuitant's  85th  birthday or ten years after the Contract  Date
       (but no later than age 88 in Pennsylvania  or, after July 1, 1998, age 90
       in New York).

       Depending on the type of retirement  arrangement in connection with which
       a Contract is issued, amounts that are distributed either too soon or too
       late may be subject to penalty taxes under the Internal Revenue Code. See
       "Federal Tax Matters." Owners should consider this carefully in selecting
       or changing a Retirement Date.

       The  Owner may  change  the  Retirement  Date  with the  Company's  prior
       approval,  by  written  request  any  time  prior  to the  issuance  of a
       supplementary   contract  which  provides  a  Benefit  Option.   The  new
       Retirement  Date  must  be  any  Anniversary  on or  before  the  maximum
       Retirement Date.

   2.  Benefit Options

       The Company currently offers only fixed Benefit Option payments; variable
       Benefit Option  payments are not currently  offered.  If the  Accumulated
       Value at the end of the Valuation  Period which  contains the  Retirement
       Date is less than $5,000 or if the amount  applied under a Benefit Option
       would  result  in  a  periodic   payment  below  the  Company's   minimum
       requirements  in effect at that  time,  the  Company  may pay the  entire
       Accumulated Value, without the imposition of any charges, in a single sum
       payment to the Annuitant or other  properly  designated  payee and cancel
       the Contract.  Otherwise, the Company will apply the Accumulated Value to
       provide a fixed Benefit Option.

       Benefit  Option  payments  will be  made as  elected  by the  Owner  on a
       monthly, quarterly, semi-annual or annual basis to the Annuitant or other
       properly-designated  payee.  The  dollar  amount  of any  Benefit  Option
       payment is specified  during the entire  period of payments  according to
       the provisions of the Benefit Option selected.  There is no right to make
       any total or partial surrender after Benefit Option payments commence.

       The amount of each  Benefit  Option  payment will depend on the amount of
       Accumulated  Value  applied to the  Benefit  Option,  the form of Benefit
       Option  selected  and,  for  Benefit  Options  other  than  Fixed  Income
       described  below,  the age of the  Annuitant.  The amount of each Benefit
       Option payment  ordinarily will be higher for a male Annuitant than for a
       female Annuitant with an otherwise identical  Contract.  This is because,
       statistically,  females tend to have longer life expectancies than males.
       However,  there will be no differences between male and female Annuitants
       in any jurisdiction where such differences are not permitted. The Company
       will also make available Contracts with no such differences in connection
       with certain  employer-sponsored benefit plans. Employers should be aware
       that, under most such plans,  Contracts that make  distinctions  based on
       gender are prohibited by law.

       The Owner may select a Benefit Option form or change a previous selection
       by written  request,  which must be  received by the Company on or before
       the  Retirement  Date. If no Benefit  Option form is chosen by the Owner,
       the Company automatically applies a Life Income Benefit Option (described
       below),  with payments guaranteed for 10 years. If an Annuitant and Joint
       Annuitant have been designated under the Contract,  payments will be made
       pursuant to a Joint and Full Survivor  Income Benefit  Option  (described
       below) with payments  guaranteed for 10 years,  unless otherwise elected.
       Tax laws and  regulations  may  impose  further  restrictions  on Benefit
       Options.

       The following Benefit Options are available:

           Fixed  Income.  Payments of a fixed  amount or  payments  for a fixed
           period of at least 5 years but not more than 30 years, are made as of
           the first day of each payment  period  starting  with the  Retirement
           Date. Payments will stop after all guaranteed payments are made.

           Life  Income.  Payments  are made as of the first day of each payment
           period during the  Annuitant's  life,  starting  with the  Retirement
           Date.  No  payments  will be made  after the  Annuitant  dies.  It is
           possible for the payee to receive only one payment  under this option
           if the Annuitant dies before the second payment is due.

           Life Income with Payments  Guaranteed  for a Period of 5 to 20 Years.
           Payments are made as of the first day of each payment period starting
           on the  Retirement  Date.  Payments  will  continue  as  long  as the
           Annuitant  lives.  If the Annuitant dies before all of the guaranteed
           payments have been made,  the Company will continue  installments  of
           the guaranteed payments to the Beneficiary.

           Joint and Full Survivor Income with Payments  Guaranteed for a Period
           of 10 Years.  Payments  are made as of the first day of each  payment
           period starting with the Retirement  Date.  Payments will continue as
           long as either the Annuitant or the Joint  Annuitant is alive. If the
           Annuitant  and  Joint  Annuitant  die  before  all of the  guaranteed
           payments have been made,  the Company will continue  installments  of
           the guaranteed payments to the Beneficiary.

           Joint and  Two-Thirds  Survivor Life Income.  Payments are made as of
           the first day of each payment  period  starting  with the  Retirement
           Date.  Payments  will continue as long as either the Annuitant or the
           Joint  Annuitant  is alive.  If  either  the  Annuitant  or the Joint
           Annuitant dies,  payments will continue to the survivor at two-thirds
           the original  amount.  Payments will stop when both the Annuitant and
           Joint  Annuitant  have died.  It is possible  for the payee or payees
           under this option to receive only one payment if both  Annuitants die
           before the second payment is due.

       Other Benefit Options may be made available with the Company's approval.

       Except for the Fixed Income Benefit  Option,  the mortality risk borne by
       the Company is to make Benefit Options payments (determined in accordance
       with the annuity tables and other  provisions  contained in the Contract)
       for the full life of all Annuitants regardless of how long all Annuitants
       or any individual  Annuitant  might live. This  undertaking  assures that
       neither  an  Annuitant's  own  longevity,  nor  an  improvement  in  life
       expectancy generally,  will have any adverse effect on the Benefit Option
       payments the Annuitant will receive under the Contract.  This, therefore,
       relieves the  Annuitant of the risk that he or she will outlive the funds
       accumulated  for retirement.  The Benefit Option tables  contained in the
       Contract  are based on the Annuity  Mortality  1983 Table a. These tables
       are guaranteed for the life of the Contract.

       In order to avoid tax penalties,  distributions from any Contract that is
       not a non-qualified contract must begin no later than April 1st following
       the  calendar  year in which the Owner  attains  age 70 1/2.  The minimum
       distribution  requirement  is a  distribution  in equal or  substantially
       equal  amounts over the Owner's life or over the joint lives of the Owner
       and Owner's designated beneficiary,  or a period not extending beyond the
       Owner's life  expectancy,  or the joint life  expectancy of the Owner and
       Owner's designated beneficiary.  In addition,  distribution payments must
       be made at least  annually.  Tax  penalties may also apply at the Owner's
       death on certain excess  accumulations.  Owners should consider potential
       tax penalties  with their tax advisors when electing a Benefit  Option or
       taking other distributions from the Contract.

   3.  Death of Annuitant or Other Payee

       Under the Benefit  Options offered by the Company,  the amounts,  if any,
       payable on the death of the Annuitant  during the Benefit  Option payment
       period are the  continuation  of  payments  for any  remaining  guarantee
       period or for the life of any Joint  Annuitant.  In all cases, the person
       entitled to receive  payments  also  receives  any rights and  privileges
       under the Benefit Option.

       Additional rules  applicable to such  distributions  under  Non-Qualified
       Contracts are described under "Required  Distributions  for Non-Qualified
       Contracts."  Though the rules there  described  do not apply to Contracts
       issued in connection with IRAs, Roth IRAs, SEPs, SAR/SEPs or SIMPLE-IRAs,
       similar rules apply to the plans, themselves.

CHARGES AND DEDUCTIONS

An  Annual  Fee,  a  mortality   and  expense   risks  charge  and,  in  certain
circumstances,  a Transaction Fee and state premium taxes are deducted under the
Contract.  Also, in certain  circumstances,  a Surrender  Charge may be deducted
from certain cash  withdrawals  before the Retirement Date. The Company has also
reserved the right to assess a daily Administrative Expense Charge.

There  are also  deductions  from and  expenses  paid out of the  assets  of the
Accounts which are described in the Fund prospectus.

A.   Annual Fee

     An Annual Fee equal to the lesser of $30 or 2% of the  Owner's  Accumulated
     Value is deducted on the day before each Contract  Anniversary prior to the
     Retirement  Date. (This charge will be lower to the extent legally required
     in some  states.)  The Annual Fee will be  deducted  from  either the Fixed
     Account  Value or the  Owner's  interest  in a Separate  Account  Division,
     whichever  has the greatest  value on the date the fee is deducted.  If the
     Contract  is fully  surrendered,  the full amount of the Annual Fee will be
     deducted at the time of surrender.  The Annual Fee currently does not apply
     to Contracts that have an Accumulated  Value of at least $30,000 on the day
     before   the   Contract   Anniversary.   This   charge  is  to  help  cover
     administrative   costs  such  as  those  incurred  in  issuing   Contracts,
     establishing  and  maintaining  the records  relating to Contracts,  making
     regulatory filings and furnishing  confirmation  notices,  voting materials
     and other  communications,  providing  computer,  actuarial and  accounting
     services,  and  processing  Contract  transactions.  The  Company  does not
     anticipate any profit from this charge.

B.   Mortality and Expense Risks Charge

     The Company will assess each Division of the Separate  Account with a daily
     charge for mortality and expense risks at a nominal annual rate of 1.25% of
     the  average  daily net  assets of the  Separate  Account.  This  charge is
     assessed only prior to the Retirement  Date. The Company  guarantees not to
     increase  this  charge for the  duration  of the  Contract.  This charge is
     assessed daily when determining the value of an accumulation Unit.

     The Company  bears a mortality  risk in that it  guarantees  to pay a death
     benefit  in a single  sum (which may also be taken in the form of a Benefit
     Option)  upon the death of an  Annuitant  or Owner prior to the  Retirement
     Date. No Surrender  Charge is imposed upon the payment of a death  benefit,
     which places a further mortality risk on the Company.

     The expense risk  assumed is that actual  expenses  incurred in  connection
     with  issuing and  administering  the  Contracts  will exceed the limits on
     administrative charges set in the Contracts.

     If the  mortality  and expense  risks charge is  insufficient  to cover the
     costs assumed,  the loss will be borne by the Company.  Conversely,  if the
     amount deducted proves more than  sufficient,  the excess will be profit to
     the Company.  The Company  expects a profit from the  mortality and expense
     risks charge.

C.   Transaction Fee

     A  Transaction  Fee of $30 applies to each  unscheduled  partial  surrender
     after the first such  surrender  made during a Contract  Year.  The Company
     will  charge a $30  Transaction  Fee to each  unscheduled  transfer  from a
     Division   after  the  twelfth  such  transfer  in  a  Contract  Year.  The
     Transaction  Fee will be deducted  from the Fixed  Account Value and/or the
     Owner's  interest in a Separate  Account  Division from which the amount is
     surrendered or transferred, on a pro rata basis.

D.   Premium Taxes

     The Company has reserved  the right to deduct  amounts to cover any premium
     taxes that are imposed by states or other  jurisdictions,  when applicable.
     Any such  deduction  will be made  from  either  a  Purchase  Payment  when
     received by the Company,  or the  Accumulated  Value when  surrendered  (in
     whole or part) or applied under a Benefit Option.

E.   Surrender Charge

     No sales charge is collected or deducted at the time Purchase  Payments are
     applied  under a Contract.  A Surrender  Charge will be assessed on certain
     total or partial surrenders. The amounts obtained from the Surrender Charge
     will be used to  partially  defray  expenses  incurred  in the  sale of the
     Contract,  including  commissions  and other  promotional  or  distribution
     expenses  associated  with the marketing of the Contract.  If the Surrender
     Charge is insufficient to cover the actual cost of distribution, such costs
     will be paid from the Company's General Account assets,  which will include
     profit, if any, derived from the mortality and expense risks charge.

     The Surrender  Charge for any full or partial  surrender is a percentage of
     the Purchase  Payments  withdrawn or surrendered  which were received by us
     during the seven completed  Contract Year period prior to the withdrawal or
     surrender.  The  applicable  percentage  which is applied to the sum of the
     Purchase  Payments  paid  during  each  Contract  Year,  is  determined  in
     accordance with the following table.

                           TABLE OF SURRENDER CHARGES

                                           Surrender Charge
                                        Applied to all Purchase
          Years since Purchase           Payments Received in
              Payment made                that Contract Year

         2 years or less                         6%
         more than 2 years, up to 3 years        5%
         more than 3 years, up to 4 years        4%
         more than 4 years, up to 5 years        3%
         more than 5 years, up to 6 years        2%
         more than 7 years                       0%

     For this purpose, it is assumed that amounts are withdrawn in the following
     order: (1) From Purchase  Payments  received by the Company more than seven
     completed Contract Years prior to the withdrawal or surrender; (2) From the
     Free Surrender  Privilege described below (from contract earnings first, if
     any, and then from Purchase Payments on a first-in,  first-out basis);  and
     (3) From  Purchase  Payments  received  by the  Company  within  the  seven
     completed  Contract  Year period prior to the  withdrawal or surrender on a
     first-in  first-out  basis.  There  is no  Surrender  Charge,  under  these
     guidelines,  on  withdrawals  of  Purchase  Payments  made more than  seven
     completed  Contract  Years prior to the  withdrawal or  surrender,  nor are
     there  Surrender  Charges  imposed  on  withdrawals  of the Free  Surrender
     Privilege.

     No  surrender  charge  will be  imposed  where  prohibited  by  state  law,
including:

     a)  State of New Jersey - no  surrender  charge  will be imposed  upon full
         surrender  on or after the later of the  Annuitant's  age 64 or 4 years
         after the Contract Date.

     b)  State of  Washington  - no  surrender  charge will be imposed upon full
         surrender on or after the later of the  Annuitant's  age 70 or 10 years
         after the Contract date.

     Waiver of the Surrender Charge. The Surrender Charge will not apply:

     1.  To any amount applied under a Benefit Option;

     2.  To the payment of a Death Benefit,  but the Surrender Charge will apply
         to Purchase Payments made by the  participant's  surviving spouse after
         the participant's date of death occurring on or after July 1, 1996;

     3.  To  any  amount   distributed  to  satisfy  the  minimum   distribution
         requirement of Sec. 401(a)9 of the Internal Revenue Code;

     4.  Where  permitted  by state law,  to a  withdrawal  made after the first
         Anniversary  as a result of the Owner's or  Annuitant's  Critical  Need
         provided that:

         (a)  the Owner or Annuitant to which the Critical Need applies is the 
              original Owner or Annuitant;

         (b)  the Critical Need did not exist prior to the Contract Date; and

         (c)  if the Critical Need is Confinement to a Health Care Facility, the
              confinement  must continue for at least 60 consecutive  days after
              Contract Date and the  withdrawal  must occur within 90 days after
              confinement  ends. No additional  Purchase Payments may be made to
              the Contract if the Company  waives the Surrender  Charge due to a
              Critical Need.

     5.  To the Free Surrender Privilege which is an amount surrendered during a
         Contract Year in an amount not to exceed the greater of:

         (a)  Earnings in the Contract
              (Earnings = Accumulated Value less unsurrendered Purchase Payments
               as of the surrender date); or

         (b)  10%  of the  Purchase  Payments  still  subject  to the  Surrender
              Charge,  decreased  by  any  partial  surrenders  since  the  last
              Anniversary.

     6.  To any  amount  transferred  from  the  Contract  to a  Single  Premium
         Immediate  Annuity  issued by the Company  after the  seventh  Contract
         Year.

     7.  To any  amount  transferred  from a  Contract  used  to  fund an IRA to
         another  annuity  contract  issued by the Company to fund an IRA of the
         participant's  spouse  when  the  distribution  is made  pursuant  to a
         divorce decree.

F.   Administrative Expense Charge

     The  Company  reserves  the right to assess each  Division of the  Separate
     Account with a daily charge at a nominal annual rate of .15% of the average
     daily net assets of the  Division.  This charge would be imposed only prior
     to the Retirement  Date. The daily  Administrative  Expense Charge would be
     assessed  to help cover  administrative  expenses  such as those  described
     under  "Annual  Fee." The daily  Administrative  Expense  Charge,  like the
     Annual  Fee,  is designed to defray  expenses  actually  incurred,  without
     profit.  Even if the Administrative  Expense Charge was imposed,  the total
     anticipated  revenues  from both  charges  are not  expected  to exceed the
     actual administrative costs incurred by the Company.

G.   Special Provisions for Group or Sponsored Arrangements

     Where permitted by state  insurance laws,  Contracts may be purchased under
     group or  sponsored  arrangements,  as well as on an  individual  basis.  A
     "group arrangement"  includes a program under which a trustee,  employer or
     similar  entity  purchases  Contracts  covering a group of individuals on a
     group basis.  A "sponsored  arrangement"  includes a program under which an
     employer  permits group  solicitation  of its  employees or an  association
     permits group  solicitation of its members for the purchase of Contracts on
     an individual basis.

     The charges and  deductions  described  above may be reduced for  Contracts
     issued  in   connection   with  group  or  sponsored   arrangements.   Such
     arrangements  may include  sales  without or reduced  mortality and expense
     risk charges  and/or  without  annual fees and/or  Surrender  Charges.  The
     Company will reduce the above charges and deductions in accordance with its
     rules in effect as of the date an  application  for a Contract is approved.
     To qualify for such a  reduction,  a group or  sponsored  arrangement  must
     satisfy certain  criteria as to, for example,  size of the group,  expected
     number of participants  and anticipated  purchase  payments from the group.
     Generally,  the  sales  contacts  and  effort,   administrative  costs  and
     mortality  cost per Contract  vary based on such factors as the size of the
     group or  sponsored  arrangements,  the purposes  for which  Contracts  are
     purchased  and  certain  characteristics  of its  members.  The  amount  of
     reduction and the criteria for qualification will reflect the reduced sales
     effort and administrative costs resulting from, and the different mortality
     experience  expected  as a  result  of,  sales  to  qualifying  groups  and
     sponsored arrangements.

     The  Company  may modify from time to time,  on a uniform  basis,  both the
     amounts of  reductions  and the criteria for  qualification.  Reductions in
     these  charges  will not be  unfairly  discriminatory  against  any person,
     including the affected  contract  owners and all other contract owners with
     contracts funded by the Separate Account.

FIXED ACCOUNT

Owners may allocate  Purchase  Payments  and transfer  amounts from the Separate
Account to the Fixed Account, in which case such amounts are held in the General
Account  of the  Company.  Because of  exemptive  and  exclusionary  provisions,
interests in the Fixed Account have not been registered under the Securities Act
of 1933 and the General Account has not been registered as an investment company
under the Investment Company Act of 1940. Accordingly, neither the Fixed Account
nor any interests  therein are subject to the provisions of these acts and, as a
result, the staff of the Securities and Exchange Commission has not reviewed the
disclosures  in this  Prospectus  relating  to the  Fixed  Account.  Disclosures
regarding  the Fixed  Account  may,  however,  be subject  to certain  generally
applicable  provisions of the federal  securities  laws relating to the accuracy
and  completeness  of  statements  made  in  prospectuses.  This  Prospectus  is
generally intended to serve as a disclosure document only for the aspects of the
Contract  involving the Separate Account and contains only selected  information
regarding the Fixed Account. More information regarding the Fixed Account may be
obtained from the Company's home office or from a sales representative.

General Description

The Company's obligations with respect to the Fixed Account are supported by the
Company's  General  Account.  Subject to  applicable  law,  the Company has sole
discretion over the investment of the assets in the General Account.

The Company  guarantees  that Purchase  Payments  allocated to the Fixed Account
will  accrue  interest  at a  guaranteed  interest  rate.  In no event  will the
guaranteed  interest  rate be less than 3%  compounded  annually.  Each Purchase
Payment  or  amount  transferred  to the Fixed  Account  earns  interest  at the
guaranteed rate in effect on the date it is received or  transferred.  This rate
applies  to each  Purchase  Payment or amount  transferred  until the end of the
Contract Year.

Each Anniversary the Company declares a renewal interest rate that is guaranteed
and applies to the Fixed  Account  Value in  existence  at that time.  This rate
applies  until  the end of the  Contract  Year.  Interest  is  earned  daily and
compounded  annually  at the end of each  Contract  Year.  Once  credited,  such
interest will be guaranteed and will become part of the Accumulated Value in the
Fixed Account from which deductions for fees and charges may be made.

Charges  under the Contract  are the same as when the Separate  Account is being
used,  except that the 1.25% per year charged for  mortality  and expense  risks
and, if applicable,  the .15% per year charged for  administrative  expenses are
not imposed on amounts of Accumulated Value in the Fixed Account.

Fixed Account Value

The  Contract's  Fixed  Account  Value on any  Valuation  Date is the sum of the
Purchase  Payments  allocated to the Fixed Account,  plus any transfers from the
Separate  Account,  plus  interest  credited  to the  Fixed  Account,  less  any
surrenders,  Surrender Charges, Annual Fees or Transaction Fees allocated to the
Fixed Account or transfers to the Separate Account.

Fixed Account Transfers, Total and Partial Surrenders

Amounts  in the Fixed  Account  are  generally  subject  to the same  rights and
limitations and will be subject to the same charges as are amounts  allocated to
the  Divisions  of the  Separate  Account  with  respect  to total  and  partial
surrenders. See "Total and Partial Surrenders."

Transfers out of the Fixed Account have special  limitations.  No transfers from
the Fixed Account may be made after the Retirement Date. Prior to the Retirement
Date,  Owners may transfer part or all of the  Accumulated  Value from the Fixed
Account  to the  Separate  Account  in one of two  ways,  a single  transfer  or
pursuant to scheduled transfers, both of which are described below. An Owner may
not make both a single transfer and scheduled transfers during the same Contract
Year.

       Single Transfer.  A single transfer in an amount not to exceed 25% of the
       Owner's  Fixed  Account Value as of the later of the Contract Date or the
       last Anniversary, may be made each Contract Year during the 30-day period
       following the Contract Date or  Anniversary.  A transfer  request must be
       made by the owner within such 30-day period.  An Owner may transfer up to
       the entire Fixed Account Value if the Owner's Fixed Account Value is less
       than $1,000 or the renewal  interest  rate declared for the Owner's Fixed
       Account Value is more than one percentage point lower than the average of
       the Owner's total Fixed Account Value earnings for the preceding Contract
       Year.  The Company  will notify the Owner if the  renewal  interest  rate
       falls to that  threshold.  The  minimum  transfer  amount is $100 (or, if
       less, the entire amount of the Fixed Account Value).

       Scheduled  Transfers.  The Owner may  elect to have  automatic  transfers
       completed  on a monthly  basis from the Fixed  Account to any Division of
       the Separate  Account.  Scheduled  transfers are available from the Fixed
       Account only if the Owner's Fixed Account Value equals or exceeds  $5,000
       at the time scheduled transfers are initiated.  (The Company reserves the
       right to change that amount but it will never  exceed  $10,000.) An Owner
       may  establish  scheduled  transfers by sending a written  request to the
       Company at its home office or by telephone.  Scheduled  transfers will be
       completed  on a monthly  basis on the date (other than the 29th,  30th or
       31st)  specified by the Owner.  If the requested  date is not a Valuation
       Date, the transfer will be completed on the next valuation date following
       such  specified  date.  Scheduled  monthly  transfers of an amount not to
       exceed 2% of the Owner's  Fixed  Account  Value at the  beginning  of the
       Contract  Year or current  value will  continue  until the Fixed  Account
       Value is exhausted or until the Owner notifies the Company to discontinue
       the  scheduled  transfers.  The minimum  transfer  amount is $100 (or, if
       less, the entire amount of the Fixed Account Value). The beginning of the
       Contract  Year  value will be used to  calculate  the 2% unless the Owner
       specifies  current  value.  If  the  Owner   discontinues  the  scheduled
       transfers,  transfers  may not begin again  without the  Company's  prior
       approval.

GENERAL PROVISIONS

The Contract

The Contract,  copies of any applications,  amendments,  riders, or endorsements
attached to the  Contract,  the Contract  current  data page,  and copies of any
supplemental applications,  amendments,  endorsements, or revised Contract pages
or Contract  data pages  which are mailed to the Owner are the entire  Contract.
Only the  Company's  corporate  officers  can  agree  to  change  or  waive  any
provisions of a Contract.  Any change or waiver must be in writing and signed by
one of these representatives of the Company.

Postponement of Payments

Any total or partial  surrender to be made from the Contract will be made within
seven days after acceptable  Notice for such payment is received by the Company,
or such  earlier  date as required by law.  However,  payment of any amount upon
total surrender, partial surrender, death, or the transfer to or from a Division
of the  Separate  Account  may be  deferred  during any period when the right to
redeem  Mutual Fund shares is  suspended as permitted  under  provisions  of the
Investment  Company Act of 1940,  as amended.  The right to redeem shares may be
suspended  during any period when (a) trading on the New York Stock  Exchange is
restricted  as  determined  by the  Securities  and Exchange  Commission or such
Exchange  is closed for other  than  weekends  and  holidays;  (b) an  emergency
exists, as determined by the Securities and Exchange Commission,  as a result of
which  (i)  disposal  by  the  Mutual  Fund  of  securities  owned  by it is not
reasonably  practicable or (ii) it is not reasonably  practicable for the Mutual
Fund to fairly  determine the value of its net assets;  or (c) the Commission by
order so permits for the protection of security  holders.  If any deferment of a
surrender is in effect and has not been cancelled by written notification to the
Company  within the period of  deferment,  the amount to be  withdrawn  shall be
determined as of the first Valuation Date following  expiration of the permitted
deferment, and the surrender will be made within seven days thereafter.

The  Company  may  also  defer  for up to 15  days  the  payment  of any  amount
attributable to a Purchase  Payment made by check to allow the check  reasonable
time to clear. The Company may also defer payment of surrender  proceeds payable
out of the Fixed Account for a period of up to 6 months.

Misstatement of Age or Sex and Other Errors

If the age or, where applicable, gender of the Annuitant has been misstated, any
amount  payable will be that which would have been  purchased at the correct age
and  gender.  If the  Company  has made any  overpayments  because of  incorrect
information about age or gender, or any error or miscalculation,  it will deduct
the overpayment from the next payment or payments due.  Underpayments  are added
to the next payment.

Assignment

Ownership of a  non-qualified  contract may be assigned.  The Company assumes no
responsibility for the validity of any assignment.  An assignment or pledge of a
Contract may have adverse tax consequences. See "Federal Tax Matters."

An  assignment  must be made in writing  and filed with the  Company at its home
office. Owner, Annuitant and Beneficiary rights are subject to any assignment of
record at the  Company's  home  office.  Any amount paid to an assignee  will be
treated as a partial surrender and will be paid in a single sum.

Change of Owner

The Owner may change  ownership of the Contract at any time. A request to change
ownership  must be in writing  and must be approved  by the  Company.  After the
Company  approves  of the  change,  the change is  effective  as of the date the
written  request  for the  change  was  signed by the  Owner.  The waiver of the
Contingent  Deferred Sales Charge for withdrawals made due to a Critical Need of
the Owner, is not available if Ownership is changed. See "Surrender Charge."

Beneficiary

Before the Retirement Date and while the Annuitant is living, the Owner may name
or change the Owner's or Annuitant's  Beneficiary or a successor  Beneficiary by
sending a written request of the change to the Company. Under certain retirement
programs,  however,  spousal  consent  may be  required  to  name  or  change  a
Beneficiary,  and the right to name a  Beneficiary  other than the spouse may be
subject to applicable tax laws and  regulations.  The Company is not responsible
for the  validity of any change.  A change will take effect as of the date it is
signed but will not affect any payments  made or action taken before the Company
receives and approves the written request. The Company also needs the consent of
any irrevocably named person before making a requested change.

If no  Beneficiary  designated as the  Annuitant's  Beneficiary is living at the
time of the Annuitant's death, any benefits otherwise payable under the Contract
to the  Beneficiary  will be paid to the  Owner,  if  living,  otherwise  to the
Annuitant's  estate.  If a Beneficiary  dies while receiving  payments under the
Contract,  and if no other  Beneficiary is then living,  any remaining  benefits
owed under the Contract will be paid to such Beneficiary's estate.

Reports

We will mail to the Owner at the last known address of record a statement of the
Owner's  current  Accumulated  Value  at  least  once  each  year  prior  to the
Retirement  Date and any reports  required by any  applicable law or regulation.
After the Retirement  Date,  any reports will be mailed to the person  receiving
Benefit Option payments, rather than to the Owner.

Quarterly  statements  reflecting  purchases and surrenders occurring during the
quarter as wall as balance of units owned and account values.

RIGHTS RESERVED BY THE COMPANY

The Company  reserves  the right to make certain  changes if, in its  judgement,
they  would  best  serve the  interests  of Owners  and  Annuitants  or would be
appropriate  in carrying  out the purpose of the  Contract.  Any changes will be
made only to the extent and in the manner  permitted by applicable  laws.  Also,
when  required  by law,  the Company  will  obtain the  Owner's  approval of the
changes and approval from any appropriate  regulatory  authority.  Such approval
may not be required in all cases,  however.  Examples of the changes the Company
may make include:

     o   To transfer any assets in any Division to another  Division,  or to the
         Fixed  Account;  or to  add,  combine  or  eliminate  Divisions  in the
         Separate Account.

     o   To substitute the shares of an Account for the Account shares held in 
         any Division:

         1)  if shares of an Account are no longer available for investment; or

         2)  if in the Company's  judgement,  investment  in an Account  becomes
             inappropriate considering the purposes of the Separate Account.

DISTRIBUTION OF THE CONTRACT

The Contract,  which is continuously  offered, will be sold primarily by persons
who are insurance agents of or brokers for the Company  authorized by applicable
law to sell life and other forms of personal  insurance and variable  annuities.
In addition, these persons will usually be registered representatives of Princor
Financial Services Corporation,  The Principal Financial Group, Des Moines, Iowa
50392-0200, a broker-dealer registered under the Securities Exchange Act of 1934
and a member of the National  Association of Securities  Dealers,  Inc.  Princor
Financial  Services  Corporation,  the  principal  underwriter,  is paid 6.5% of
Purchase   Payments  by  Principal   Mutual  Life  Insurance   Company  for  the
distribution  of the  Contract.  The  Contract  may also be sold  through  other
selected broker-dealers  registered under the Securities Exchange Act of 1934 or
firms  that are  exempt  from  such  registration.  Princor  Financial  Services
Corporation is also the principal  underwriter for various registered investment
companies organized by the Company.  Princor Financial Services Corporation is a
wholly-owned subsidiary of Principal Holding Company.  Principal Holding Company
is a holding company and a wholly-owned subsidiary of the Company.

PERFORMANCE CALCULATION

The  Separate  Account  may  publish   advertisements   containing   information
(including graphs,  charts, tables and examples) about the performance of one or
more of its  Divisions.  The  Contract  was not offered  prior to June 16, 1994.
However,  shares of the Aggressive  Growth,  Asset Allocation,  Balanced,  Bond,
Capital Value, Government Securities,  Growth,  International,  MidCap and Money
Market Divisions of the Separate Account invest were offered prior to that date.
Thus, the Separate  Account may publish  advertisements  containing  information
about the  hypothetical  performance  of one or more of its  Divisions  for this
Contract had the Contract  been issued on or after the date the Account in which
such Division invests was first offered.  The hypothetical  performance from the
date of  inception  of the Account in which the  Division  invests is derived by
reducing  the  actual  performance  of the  underlying  Account  by the fees and
charges of the Contract as if it had been in existence.

The International  SmallCap,  MicroCap,  MidCap Growth,  Real Estate,  SmallCap,
SmallCap Growth,  SmallCap Value and Utilities Divisions of the Separate Account
were not offered until May 1, 1998. Performance data for these Divisions will be
calculated utilizing standardized performance formulas and will show performance
since the inception date of such Division.

The yield and total return  figures  described  below will vary  depending  upon
market conditions,  the composition of the underlying  Account's  portfolios and
operating expenses.  These factors and possible  differences in the methods used
in  calculating  yield and total return should be considered  when comparing the
Separate Account  performance figures to performance figures published for other
investment  vehicles.  The Separate  Account may also quote rankings,  yields or
returns as published  by  independent  statistical  services or  publishers  and
information  regarding  performance of certain market  indices.  Any performance
data quoted for the Separate Account represents only historical  performance and
is not intended to indicate future  performance.  For further information on how
the  Separate  Account  calculates  yield  and  total  return  figures,  see the
Statement of Additional Information.

From time to time the Separate  Account  advertises its Money Market  Division's
"yield" and "effective yield" for these Contracts.  Both yield figures are based
on historical earnings and are not intended to indicate future performance.  The
"yield" of the Division  refers to the income  generated by an investment in the
Division  over  a  seven-day   period  (which  period  will  be  stated  in  the
advertisement).  This income is then "annualized." That is, the amount of income
generated by the  investment  during that week is assumed to be  generated  each
week over a 52-week period and is shown as a percentage of the  investment.  The
"effective  yield" is  calculated  similarly  but, when  annualized,  the income
earned by an  investment  in the  Division  is  assumed  to be  reinvested.  The
"effective  yield"  will be  slightly  higher  than the  "yield"  because of the
compounding  effect  of  this  assumed  reinvestment.  Neither  yield  quotation
reflects a sales load deducted from Purchase Payments which, if included,  would
reduce the "yield" and "effective yield."

In addition,  from time to time, the Separate Account will advertise the "yield"
for  certain  other  Divisions  for the  Contract.  The "yield" of a Division is
determined by  annualizing  the net  investment  income per unit for a specific,
historical  30-day period and dividing the result by the ending maximum offering
price of the unit for the same period.  This yield  quotation does not reflect a
contingent deferred sales charge which, if included, would reduce the "yield."

Also, from time to time, the Separate  Account will advertise the average annual
total return of its various  Divisions.  The average annual total return for any
of the Divisions is computed by calculating  the average annual  compounded rate
of return over the stated period that would equate an initial $1,000  investment
to the ending redeemable Contract value. In this calculation the ending value is
reduced by a Surrender  Charge that  decreases  from 6% to 0% over a period of 7
years.  The Separate  Account may also  advertise  total  return  figures of its
Divisions  for a specified  period that do not take into  account the  Surrender
Charge in order to illustrate the change in the Division's unit value over time.
See "Charges and Deductions" and "Surrender Charge."

VOTING RIGHTS

The Company shall vote Account shares held in Separate  Account B at regular and
special  meetings  of  shareholders  of each  Account,  but will  follow  voting
instructions  received  from  Owners of the  Contract  whose  Accumulated  Value
includes amounts invested in the corresponding Division of the Separate Account.

The number of Account  shares as to which an Owner has the voting  interest will
be  determined  by the  Company as of a date which will not be more than  ninety
days  prior to the  meeting of the  Account,  and  voting  instructions  will be
solicited by written  communication at least ten days prior to the meeting.  The
number of Account shares held in Separate  Account B which are  attributable  to
the Owner's interest in each Division is determined by dividing the value of the
Owner's  interest  in that  Division  by the net asset value of one share of the
underlying Account.  Account shares for which Owners are entitled to give voting
instructions,  but for which none are received,  and shares of the Account owned
by the Company will be voted in the same proportion as the aggregate  shares for
which voting instructions have been received.

Proxy material will be provided to each Owner together with an appropriate  form
which may used to give voting instructions to the Company.

If the Company determines pursuant to applicable law that Account shares held in
Separate  Account B need not be voted  pursuant to  instructions  received  from
Owners,  then the Company may vote Account shares held in Separate  Account B in
its own right.

FEDERAL TAX MATTERS

The  following  description  is a general  summary of the tax  rules,  primarily
related  to federal  income  taxes,  which in the  opinion  of the  Company  are
currently  in  effect.   These  rules  are  based  on  laws,   regulations   and
interpretations  which are  subject to change at any time.  This  summary is not
comprehensive  and is not  intended as tax advice.  Federal  estate and gift tax
considerations,  as well as state and local taxes, may also be material.  Owners
should  consult a  qualified  tax adviser as to the tax  implications  of taking
action under a Contract or related retirement plan.

Non-Qualified Contracts

Section 72 of the  Internal  Revenue  Code  ("Code")  governs  the  taxation  of
annuities in general.  Purchase Payments made under non-qualified  contracts are
not  excludible  or  deductible  from the gross income of the Owner or any other
person.  However,  any  increase  in the  Accumulated  Value of a  non-qualified
contract  resulting from the investment  performance of the Separate  Account or
interest  credit to the Fixed  Account is generally  not taxable to the Owner or
other payee until received by him or her, as surrender  proceeds,  death benefit
proceeds, or otherwise.  The exception to this rule is that,  generally,  Owners
who are not  natural  persons  are  immediately  taxed  on any  increase  in the
Accumulated Value. However, this exception does not apply in all cases.

The  following  discussion  applies  generally  to  Contracts  owned by  natural
persons.

In  general,  surrenders  or partial  surrenders  under  Contracts  are taxed as
ordinary  income to the  extent  of the  accumulated  income  or gain  under the
Contract.  If an Owner  assigns or pledges  any part of the value of a Contract,
the value so pledged or assigned is taxed to the Owner as ordinary income to the
same extent as a partial withdrawal.

With respect to Benefit Options payments, although the tax consequences may vary
depending on the option elected under the Contract,  until the investment in the
Contract is recovered, generally only the portion of the payment that represents
the  amount  by which the  Accumulated  Value  exceeds  the  "investment  in the
contract" will be taxed. In general, an Annuitant's or other payee's "investment
in the  contract" is the  aggregate  amount of Purchase  Payments made by him or
her. After the "investment in the contract" is recovered, the full amount of any
additional  Benefit  Option  payments  is  taxable.  Prior  to  recovery  of the
"investment  in the  contract,"  there is no tax on the  amount of each  payment
which bears the same ratio to such payment that the "investment in the contract"
bears to the total  expected  return under the  Contract.  The remainder of each
Benefit Option  payment is taxable.  The taxable  portion of a  distribution  is
taxed as ordinary income.

For  purposes  of  determining  the  amount of  taxable  income  resulting  from
distributions,  all Contracts and other annuity  contracts issued by the Company
or its  affiliates  to the same  Owner  within  the same  calendar  year will be
treated as if they were a single contract.

With respect to IRAs or IRA rollovers,  there is a 10% penalty under the Code on
the taxable  portion of a "premature  distribution."  Generally,  an amount is a
"premature  distribution"  unless the  distribution  is (1) made on or after the
Owner  reaches age 59 1/2,  (2) made to a  Beneficiary  on or after death of the
Owner,  (3) made  upon the  disability  of the  Owner,  (4) part of a series  of
substantially  equal  periodic  payments for the life or life  expectancy of the
Owner or the Owner and  Beneficiary  (5) made to pay medical  expenses,  (6) for
certain unemployment  expenses,  (7) for first home purchases (up to $10,000) or
8) for higher  education  expenses.  Premature  distributions  may  result,  for
example,  from an early Retirement Date, any early surrender,  partial surrender
or  assignment  of a Contract or the death of an Annuitant  who is not the Owner
prior to the Owner attaining age 59 1/2.

With  respect to  SIMPLE-IRAs,  in place of the above 10%  penalty on  premature
distributions,  there is a 25% penalty on distributions made within two years of
the initial  contribution unless the distribution is made for one or more of the
reasons listed in the preceding paragraph.

A transfer of ownership of a Contract,  or  designation of an Annuitant or other
payee who is not also the  Owner,  may  result  in a certain  income or gift tax
consequences to the Owner that are beyond the scope of this discussion. An Owner
contemplating  any  transfer  or  assignment  of a  Contract  should  contact  a
competent  tax  advisor  with  respect  to the  potential  tax  effects  of such
transactions.

Required Distributions for Non-Qualified Contracts

In order for a non-qualified  contract to be treated as an annuity  contract for
federal  income tax  purposes,  Section  72(s) of the Code  requires  (a) if the
person receiving  payments dies on or after the Retirement Date but prior to the
time the entire  interest in the Contract has been  distributed,  the  remaining
portion of such  interest will be  distributed  at least as rapidly as under the
method of distribution being used as of the date of that person's death; and (b)
if any Owner dies prior to the  Retirement  Date,  the  entire  interest  in the
Contract  will be  distributed  (1)  within  five  years  after the date of that
Owner's  death or (2) as annuity  payments  which will begin  within one year of
that  Owner's  death  and  which  will  be made  over  the  life of the  Owner's
designated Beneficiary or over a period not extending beyond the life expectancy
of that  Beneficiary.  However,  if the Owner's  designated  Beneficiary  is the
surviving  spouse of the Owner, the Contract may be continued with the surviving
spouse deemed to be the new Owner for purposes of Section 72(s). Where the Owner
or other  person  receiving  payments  is not a  natural  person,  the  required
distributions  provided for in Section 72(s) apply upon the death of the primary
Annuitant.

Generally,  unless the Beneficiary elects otherwise, the above requirements will
be  satisfied  prior to the  Retirement  Date by paying  the death  benefit in a
single sum, subject to proof of the Owner's death. The Beneficiary, however, may
elect by  written  request  to  receive a Benefit  Option  instead of a lump sum
payment.  However,  if the  election  is not made within 60 days of the date the
single sum death benefit  otherwise  becomes payable,  the IRS may disregard the
election for tax purposes and tax the Beneficiary as if a single sum payment had
been made.

IRA, SEP, SAR/SEP, SIMPLE-IRA and ROTH-IRA

The  Contract  may be  used to fund  IRAs,  SEPs,  SAR/SEPs  ,  SIMPLE-IRAs  and
ROTH-IRAs.  In  addition,  in  certain  states  the  Contract  may be  used  for
conversion of an existing IRA funded with a fixed annuity contract issued by the
Company into a ROTH-IRA. The surrender charge that would otherwise be imposed on
surrenders  from the fixed  annuity  will be  waived.  The  number of years that
assets were in the fixed  annuity  contract will be credited to the new Contract
for  calculation  of  Surrender  Charge.  If an existing IRA is funded with this
Contract is surrendered  and the proceeds  converted into ROTH-IRA funded with a
fixed annuity contract issued by the Company,  the surrender charges which would
otherwise  be  imposed  under this  Contract  will be  waived.  This  conversion
privilege is not available in New Jersey.

The tax rules  applicable to Owners,  Annuitants and other payees vary according
to the type of plan and the terms and conditions of the plan itself. In general,
Purchase Payments made under a retirement  program  recognized under the Code by
or on behalf of an individual are excludible from the individual's  gross income
for tax purposes  prior to the  Retirement  Date.  The  portion,  if any, of any
Purchase  Payment made by or on behalf of an individual under a Contract that is
not excluded from the individuals' gross income for tax purposes constitutes the
individual's  "investment in the contract."  Aggregate deferrals under all plans
at the employee's option may be subject to limitations.  The tax implications of
these plans are further  discussed in the  Statement of  Additional  Information
under the heading "Taxation Under Certain Retirement Plans."

Withholding

Benefit  Option  payments  and other  amounts  received  under the  Contract are
subject to income tax withholding  unless the recipient elects not to have taxes
withheld.  The amounts withheld will vary among recipients  depending on the tax
status of the individual and the type of payments from which taxes are withheld.

Notwithstanding  the  recipient's  election,  withholding  may be required  with
respect to certain payments to be delivered outside the United States. Moreover,
special  "backup  withholding"  rules may require the Company to  disregard  the
recipient's  election if the recipient  fails to supply the Company with a "TIN"
or taxpayer  identification number (social security number for individuals),  or
if the Internal  Revenue  Service  notifies the Company that the TIN provided by
the recipient is incorrect.

Mutual Fund Diversification

The United States  Treasury  Department  has adopted  regulations  under Section
817(h)  of the Code  which  establishes  standards  of  diversification  for the
investment underlying the Contracts. Under this Code Section, Separate Account B
investments  must be  adequately  diversified  in order for the  increase in the
value of non-qualified  contracts to receive tax-deferred treatment. In order to
be adequately diversified,  the portfolio of each underlying Account must, as of
the end of each calendar quarter or within 30 days thereafter, have no more than
55% of its assets  invested in any one investment,  70% in any two  investments,
80% in any three  investments  and 90% in any four  investments.  Failure  of an
Account to meet the  diversification  requirements could result in tax liability
to non-qualified contractholders.

The investment  opportunities  of the Accounts  could  conceivably be limited by
adhering  to the above  diversification  requirements.  This  would  affect  all
Owners,  including those Owners of contracts for whom  diversification  is not a
requirement for tax-deferred treatment.

STATE REGULATION

The  Company  is subject  to the laws of the State of Iowa  governing  insurance
companies and to regulation by the Insurance Department of the State of Iowa. An
annual  statement  in a  prescribed  form  must be filed by March 1 in each year
covering the  operations of the Company for the preceding year and its financial
condition  on  December  31st of such year.  Its books and assets are subject to
review or examination by the  Commissioner  of Insurance of the State of Iowa or
his  representatives  at all times,  and a full examination of its operations is
conducted  periodically by the National Association of Insurance  Commissioners.
Iowa law and regulations also prescribe permissible  investments,  but this does
not involve supervision of the investment management or policy of the Company.

In addition,  the Company is subject to the insurance  laws and  regulations  of
other states and  jurisdictions  in which it is licensed to operate.  Generally,
the insurance  departments of these states and  jurisdictions  apply the laws of
the state of domicile in determining the field of permissible investments.

LEGAL OPINIONS

Legal matters  applicable to the issue and sale of the Contracts,  including the
right of the Company to issue  Contracts  under Iowa  Insurance  Law,  have been
passed upon by Gregg R. Narber, Senior Vice President and General Counsel.

LEGAL PROCEEDINGS

There are no legal proceedings pending to which Separate Account B is a party or
which would materially affect Separate Account B.

                                   APPENDIX A

The Company hereby offers to exchange the Contract  described in this Prospectus
("PVA Contract") for certain  outstanding  Pension Builder Plus Variable Annuity
Contracts   ("Pension  Builder  Plus  Contracts")   issued  in  connection  with
Individual  Retirement  Annuity  ("IRA") plans or programs,  including  SEPs and
SAR-SEPs (but excluding employer-sponsored IRAs) adopted pursuant to Section 408
of the  Internal  Revenue Code or for such Pension  Builder Plus  Contracts  the
withdrawals  from which may be  transferred  to the  Contract  described in this
prospectus  to fund an IRA. The Company  reserves  the right to  terminate  this
exchange offer at any time. In considering  whether to accept the exchange offer
you should  consult the  Pension  Builder  Plus  Contract  Prospectus  since the
provisions and charges of the Pension Builder Plus Contract differ from those of
the PVA Contract.

The Pension  Builder  Plus  Contract may be exchanged at net asset value for the
PVA  Contract.  To effect an  exchange,  the Company must receive from you (1) a
completed  application  for the PVA Contract,  (2) a written request and release
for the exchange, and (3) the Pension Builder Plus Contract to be exchanged. The
exchange will become  effective as of the close of the Valuation Period in which
all of these three  items are  received  by the  Company at its home  office.  A
Participant's Investment Account Value of the Pension Builder Plus Contract will
be  determined  as of the  time  the  exchange  becomes  effective  and  will be
transferred to the PVA Contract. No surrender charge otherwise applicable to the
Pension  Builder  Plus  Contract  will  apply  to the  surrender  affecting  the
exchange.  The PVA Contract's  contingent deferred sales charge will be computed
as if prior  Purchase  Payments for the Pension  Builder Plus Contract have been
made for the PVA  Contract  on the date of issue  of the  Pension  Builder  Plus
Contract.  The contingent deferred sales charge for additional Purchase Payments
made under the PVA Contract after the transfer of the Accumulated Value from the
Pension Builder Plus Contract will be computed based on the number of years that
the additional  Purchase Payments to which the withdrawal is attributed has been
credited under the PVA Contract, as provided in this Prospectus.

Summary of Differences between Contracts

The Pension Builder Plus Contract and the PVA Contract differ substantially,  as
summarized below. There may be additional  differences  important to you and the
prospectuses of both contracts  should be reviewed  carefully  before making the
exchange.

Contingent Deferred Sales Charge. The contingent deferred sales charge under the
PVA Contract applies to all Purchase Payments received during any Contract Year.
The contingent  deferred  sales charge for the Pension  Builder Plus Contract is
based upon the number of Contribution Years a Participant has been covered under
the Contract (rather than on the year in which the Contribution was made). Thus,
for certain  Participants of the Pension  Builder Plus  Contracts,  new Purchase
Payments  made  after  accepting  the  exchange  offer  would be  subject to the
contingent  deferred  sales  charge  under the PVA  Contract,  but new  Purchase
Payments  made  under the  Pension  Builder  Plus  Contract  would not have been
subject to such a charge,  or would have been subject to a lesser charge had the
offer been rejected.

The  contingent  deferred  sales charge of the PVA Contract will be waived under
all of the circumstances under which the contingent deferred sales charge to the
Pension  Builder  Plus  Contract  would  be  waived  and,  in  addition  the PVA
Contract's charge does not apply to:

     1.  any amount distributed to satisfy the minimum distribution requirements
         of Section 401(a)9 of the Internal Revenue Code;

     2.  where  permitted  by state law,  to a  withdrawal  made after the first
         Anniversary as a result of the Owner's or Annuitant's Critical Need, as
         described in this Prospectus; and

     3.  to the Free Surrender Privilege as defined in this Prospectus.

Annual Fee  versus  Administration  Charge.  The PVA  Contract  is subject to an
Annual Fee equal to the lesser of $30 or 2% of the  Owner's  Accumulated  Value.
The Annual Fee currently  does not apply to Contracts  that have an  Accumulated
Value of at least  $30,000.  In addition,  the Company has reserved the right to
assess each Division of the Separate Account with a daily administrative expense
charge  at an  annual  rate of .15%  of the  average  daily  net  assets  of the
Division.  This  charge is not  currently  imposed.  The  Pension  Builder  Plus
Contract is subject to annual  Administration Charge equal to $25 plus an amount
equal to .5% of the first $50,000 of the value of all Investment Accounts of the
Participant under the Contract.  Thus, the maximum annual  Administration Charge
under the Pension Builder Plus Variable Annuity Contract is $275.

Mortality  and Expense  Risks  Charge.  The annual  mortality  and expense risks
charge of the PVA Contract is equal to 1.25% of the average  daily net assets of
the Separate Account.  The mortality and expense risks charges applicable to the
Pension  Builder  Plus  Contract are 1.4965%  (1.0001%  for Rollover  Individual
Retirement Annuities) of the average daily net assets.

Death Benefit. The benefit payable on death of the annuitant or owner of the PVA
Contract is the greater of:

     1.  the Accumulated Value on the date the Company receives Notice of death;
         or

     2.  Total  Purchase  Payments  less any partial  surrenders  and  Surrender
         Charges as of the date the Company receives Notice of death; or

     3.  the death benefit that was in effect on any prior  anniversary  that is
         divisible equally by 7, plus any Purchase Payments and less any partial
         surrenders made after that Anniversary.

The death benefit  payable  under the Pension  Builder Plus Contract is equal to
the market value of a Participant's Investment Account Values as of the date the
Company  receives proof of death.  The PVA Contract's death benefit thus will be
at least equal to, and perhaps  greater than,  that of the Pension  Builder Plus
Contract.

Right to Examine after Exchange

Persons who,  under the terms of this  exchange  offer,  exchange  their Pension
Builder  Plus  Contract for the PVA  Contract  and  subsequently  revoke the PVA
Contract  within  the  time  permitted,  as  described  in the  section  of this
Prospectus  captioned  "Right to Examine the Contract,"  will have their Pension
Builder Plus Contract automatically reinstated as of the date of revocation. The
refunded amount will be applied as the new current  Accumulated  Value under the
reinstated  Contract,  which may be more or less than it would  have been had no
exchange  and  reinstatement  occurred.  The  refunded  amount will be allocated
initially among the Divisions of the reinstated Pension Builder Plus Contract in
the same  proportion  that the value in each  Division  bore to the  transferred
Accumulated Value on the date of the exchange of the PVA Contract.  For purposes
of calculating any contingent deferred sales charge under the reinstated Pension
Builder  Plus  Contract,  the  reinstated  Contract  will be deemed to have been
issued  and to have  received  past  Purchase  Payments  as if there had been no
exchange.

INDEPENDENT AUDITORS

   
Ernst & Young LLP, Des Moines, Iowa, serve as independent auditors for Principal
Mutual Life Insurance  Company  Separate  Account B and The Principal  Financial
Group and perform audit and accounting  services for Separate  Account B and the
Principal Financial Group.
    

CALCULATION OF YIELD AND TOTAL RETURN

The  Separate  Account  may  publish   advertisements   containing   information
(including graphs,  charts, tables and examples) about the performance of one or
more of its Divisions.

The Contract  was not offered  prior to June 16, 1994.  However,  the  Divisions
invest in Accounts of the Principal Variable Contracts Fund, Inc. These Accounts
correspond to open-end  investment  companies ("mutual funds") which,  effective
January 1, 1998, were  reorganized  into the Accounts of the Principal  Variable
Contracts Fund, Inc. as follows:

           Old Mutual Fund Name                   New Corresponding Account Name
           --------------------                   ------------------------------
     Principal Aggressive Growth Fund, Inc.        Aggressive Growth Account
     Principal Asset Allocation Fund, Inc.         Asset Allocation Account
     Principal Balanced Fund, Inc.                 Balanced Account
     Principal Bond Fund, Inc.                     Bond Account
     Principal Capital Accumulation Fund, Inc.     Capital Value Account
     Principal Emerging Growth Fund, Inc.          MidCap Account
     Principal Government Securities Fund, Inc.    Government Securities Account
     Principal Growth Fund, Inc.                   Growth Account
     Principal Money Market Fund, Inc.             Money Market Account
     Principal World Fund, Inc.                    International Account

The  Accounts  (under their  former  names) were  offered  prior to the date the
Contract was available.  Thus, the Separate  Account may publish  advertisements
containing information about the hypothetical  performance of one or more of its
Divisions  for this  Contract had the contract  been issued on or after the date
the Account in which such Division  invests was first offered.  The hypothetical
performance  from the date of  inception  of the  Account in which the  Division
invests is derived by reducing the actual  performance of the underlying Account
by the fees and  charges of the  Contract  as if it had been in  existence.  The
yield and total return figures  described  below will vary depending upon market
conditions, the composition of the underlying Account's portfolios and operating
expenses.  These  factors  and  possible  differences  in the  methods  used  in
calculating  yield and total return  should be  considered  when  comparing  the
Separate Account  performance figures to performance figures published for other
investment  vehicles.  The Separate  Account may also quote rankings,  yields or
returns as published  by  independent  statistical  services or  publishers  and
information  regarding  performance of certain market  indices.  Any performance
data quoted for the Separate Account represents only historical  performance and
is not intended to indicate future performance.

From time to time the Account advertises its Money Market Division's "yield" and
"effective  yield"  for  these  Contracts.  Both  yield  figures  are  based  on
historical  earnings and are not intended to indicate  future  performance.  The
"yield" of the Division  refers to the income  generated by an investment  under
the  contract in the  Division  over a seven-day  period  (which  period will be
stated in the  advertisement).  This income is then  "annualized."  That is, the
amount of income  generated by the investment  during that week is assumed to be
generated  each week over a 52-week  period and is shown as a percentage  of the
investment.  The "effective yield" is calculated similarly but, when annualized,
the income earned by an investment in the division is assumed to be  reinvested.
The "effective  yield" will be slightly  higher than the "yield"  because of the
compounding  effect  of  this  assumed  reinvestment.  Neither  yield  quotation
reflects a sales load deducted from purchase payments which, if included,  would
reduce the "yield" and "effective yield."

In addition,  from time to time, the Separate Account will advertise the "yield"
for  certain  other  Divisions  for the  Contract.  The "yield" of a Division is
determined by  annualizing  the net  investment  income per unit for a specific,
historical  30-day period and dividing the result by the ending maximum offering
price of the unit for the same period.  This yield  quotation does not reflect a
contingent deferred sales charge which, if included, would reduce the "yield."

Also, from time to time, the Separate  Account will advertise the average annual
total return of its various  Divisions.  The average annual total return for any
of the Divisions is computed by calculating  the average annual  compounded rate
of return over the stated period that would equate an initial $1,000  investment
to the ending redeemable contract value. In this calculation the ending value is
reduced by a contingent  deferred sales charge that decreases from 6% to 0% over
a period of 7 years.  The  Separate  Account  may also  advertise  total  return
figures for its Divisions for a specified period that does not take into account
the sales charge in order to illustrate the change in the Division's  unit value
over time.  See "Charges and  Deductions"  in the Prospectus for a discussion of
contingent deferred sales charges.

Following  are the  hypothetical  average  annual  total  returns for the period
ending  December  31, 1997  assuming  the  contract  had been  offered as of the
effective dates of the underlying Accounts in which the Divisions invest:

TAXATION UNDER CERTAIN RETIREMENT PLANS

INDIVIDUAL RETIREMENT ANNUITIES

Purchase Payments.  Individuals may make contributions for individual retirement
annuity ("IRA") Contracts.  Deductible contributions for any year may be made up
to the lesser of $2,000 or 100% of compensation  for individuals who (1) are not
active  participants  in another  retirement  plan,  (2) are  unmarried and have
adjusted  gross income of $40,000 or less,  or (3) are married and have adjusted
gross income of $60,000 or less.  Such  individuals  may  establish an IRA for a
spouse who makes no contribution to an IRA for the tax year. The annual purchase
payments for both spouses'  Contracts cannot exceed the lesser of $4,000 or 100%
of  the  working  spouse's  earned  income,  and  no  more  than  $2,000  may be
contributed  to either  spouse's  IRA for any year.  Individuals  who are active
participants  in other  retirement  plans and whose  adjusted gross income (with
certain special  adjustments)  exceeds the cut-off point ($40,000 for unmarried,
$60,000 for married persons filing jointly,  and $0 for married persons filing a
separate  return) by less than  $10,000  are  entitled  to make  deductible  IRA
contributions  in  proportionately  reduced  amounts.  For  example,  a  married
individual who is an active  participant in another  retirement plan and files a
separate tax return is entitled to a partial IRA  deduction if the  individual's
adjusted  gross income is less than $10,000,  and no IRA deduction if his or her
adjusted  gross income is equal to or greater than  $10,000.  Individuals  whose
spouse is an active  participant  in other  retirement  plans and whose combined
adjusted  gross income exceeds the cutoff point of $150,000 by less than $10,000
are entitled to make deductible IRA  contributions  in  proportionately  reduced
amounts.

An individual may make  non-deductible  IRA  contributions  to the extent of the
excess of (1) the lesser of $2,000 ($4,000 in the case of a spousal IRA) or 100%
of compensation over (2) the IRA deductible  contributions  made with respect to
the individual.

An individual may not make any  contribution  to his/her own IRA for the year in
which he/she reaches age 70 1/2 or for any year thereafter.

Taxation  of  Distributions.  Distributions  from  IRA  Contracts  are  taxed as
ordinary income to the recipient,  although special rules exist for the tax-free
return of  non-deductible  contributions.  In  addition,  taxable  distributions
received  under an IRA Contract prior to age 59 1/2 are subject to a 10% penalty
tax in addition to regular income tax. Certain  distributions  are exempted from
this  penalty  tax,  including  distributions  following  the  owner's  death or
disability  if the  distribution  is paid as part of a series  of  substantially
equal periodic  payments made for the life (or life  expectancy) of the Owner or
the joint lives (or joint life expectancies) of Owner and the Owner's designated
Beneficiary;  distributions to pay medical  expenses;  distributions for certain
unemployment  expenses;  distributions  for first home purchases (up to $10,000)
and distributions for higher education expenses.

Required  Distributions.   Generally,  distributions  from  IRA  Contracts  must
commence not later than April 1 of the calendar year following the calendar year
in which the employee  attains age 70 1/2, and such  distributions  must be made
over a period that does not exceed the life  expectancy  of the employee (or the
employee and  Beneficiary).  A penalty tax of 50% would be imposed on any amount
by which the  minimum  required  distribution  in any year  exceeded  the amount
actually  distributed in that year. In addition,  in the event that the employee
dies before his or her entire interest in the Contract has been distributed, the
employee's  entire interest must be distributed in accordance with rules similar
to those  applicable  upon  the  death  of the  Contract  Owner in the case of a
non-qualified contract, as described in the Prospectus.

Tax-Free  Rollovers.  The  Code  permits  the  taxable  portion  of  funds to be
transferred  in  a  tax-free   rollover  from  a  qualified   employer  pension,
profit-sharing,  annuity,  bond purchase or tax-deferred  annuity plan to an IRA
Contract  if  certain  conditions  are met,  and if the  rollover  of  assets is
completed  within 60 days  after the  distribution  from the  qualified  plan is
received.  A direct  rollover of funds may avoid a 20%  federal tax  withholding
generally   applicable  to  qualified   plans  or   tax-deferred   annuity  plan
distributions.  In addition,  not more frequently than once every twelve months,
amounts may be rolled  over  tax-free  from one IRA to  another,  subject to the
60-day  limitation  and other  requirements.  The  once-per-year  limitation  on
rollovers does not apply to direct  transfers of funds between IRA custodians or
trustees.

SIMPLIFIED  EMPLOYEE  PENSION  PLANS AND SALARY  REDUCTION  SIMPLIFIED  EMPLOYEE
PENSION PLANS

Purchase Payments.  Under Section 408(k) of the Code,  employers may establish a
type of IRA plan  referred  to as a  simplified  employee  pension  plan  (SEP).
Employer  contributions  to a SEP cannot  exceed the lesser of $24,000 or 15% or
the  employee's  earned  income.  Employees of certain small  employers may have
contributions  made to the salary  reduction  simplified  employee  pension plan
("SAR/SEP") on their behalf on a salary reduction basis.  These salary reduction
contributions  may not exceed  $10,000 in 1998,  which is indexed for inflation.
Employees of tax-exempt  organizations  and state and local government  agencies
are not eligible for SAR/SEPs.  SAR/SEPs may not be  established  after December
31, 1996.

Taxation  of  Distributions.  Generally,  distribution  payments  from  SEPs and
SAR/SEPs are subject to the same distribution rules described above for IRAs.

Required  Distributions.  SEPs and  SAR/SEPs  are  subject  to the same  minimum
required distribution rules described above for IRAs.

Tax-Free Rollovers. Generally, rollovers and direct transfers may be made to and
from SEPs and SAR/SEPs in the same manner as described  above for IRAs,  subject
to the same conditions and limitations.

SAVINGS INCENTIVE MATCH PLANS FOR EMPLOYEES (SIMPLE IRA)

Purchase Payments.  Under Section 408(p) of the Code,  employers may establish a
type of IRA plan known as a Simple IRA. Employees may have contributions made to
the SIMPLE IRA on a salary reduction basis. These salary reduction contributions
may not exceed  $6,000 in 1998,  which is indexed for  inflation.  Total  salary
reduction  contributions  are limited to $10,000 per year for any  employee  who
makes  salary  reduction  contributions  to more  than one plan.  Employers  are
required to contribute to the SIMPLE IRA, which contributions may not exceed the
lesser of:  (1) The amount of salary  deferred  by the  employee,  (2) 3% of the
employee's  compensation,  or (3)  $6,000,  if  the  employer  contributes  on a
matching basis; or the lesser of: (1) 2% of the employee's compensation,  or (2)
$3,200, if the employer makes  non-elective  contributions.  An employer may not
make contributions to both a SIMPLE IRA and another retirement plan for the same
calendar year.

Taxation of Distributions. Generally, distribution payments from SIMPLE IRAs are
subject to the same  distribution  rules described  above for IRAs,  except that
distributions  made  within  two  years  of  the  date  of an  employee's  first
participation  in a SIMPLE IRA of an  employer  are subject to a 25% penalty tax
instead of the 10% penalty tax discussed previously.

Required  Distributions.  SIMPLE IRAs are subject to the same  minimum  required
distribution rules described above for IRAs.

Tax-Free  Rollovers.  Direct transfers may be made among SIMPLE IRAs in the same
manner  as  described  above  for  IRAs,  subject  to the  same  conditions  and
limitations.  Rollovers  from  SIMPLE  IRAs are  permitted  after two years have
elapsed from the date of an employee's  first  participation  in a SIMPLE IRA of
the employer. Rollovers to SIMPLE IRAs from other plans are not permitted.

ROTH INDIVIDUAL RETIREMENT ANNUITIES (ROTH IRA)

Purchase  Payments.  Under  Section  408A  of the  Code,  Individuals  may  make
nondeductible   contributions   to  Roth  IRA  contracts  up  to  $2,000.   This
contribution  amount must be reduced by the amount of any contributions  made to
other  IRAs  for  the  benefit  of  the  Roth  IRA  owner.  The  maximum  $2,000
contribution  is phased out for single  taxpayers  with  adjusted  gross  income
between  $95,000 and $110,000 and for joint  filers with  adjusted  gross income
between  $150,000 and $160,000.  If taxable  income is recognized on the regular
IRA, an IRA owner with adjusted gross income of less than $100,000 may convert a
regular  IRA into a Roth IRA.  If the  conversion  is made in 1998,  IRA  income
recognized may be spread over four years. Otherwise, all IRA income will need to
be  recognized in the year of  conversion.  No IRS 10% tax penalty will apply to
the conversion.

Taxation of Distribution.  Qualified  distributions are received income-tax free
by the Roth IRA owner,  or  beneficiary in case of the Roth IRA owner's death. A
qualified  distribution  is any  distribution  made  after five years if the IRA
owner  is over  age 59 1/2,  dies,  becomes  disabled,  or uses  the  funds  for
first-time home buyer expenses at the time of distribution. The five year period
for converted amounts begins from the year of the conversion.

                         Report of Independent Auditors


Board of Directors and Participants
Principal Mutual Life Insurance Company

We have audited the  accompanying  statement  of net assets of Principal  Mutual
Life  Insurance  Company  Separate  Account  B  (comprising,  respectively,  the
Aggressive  Growth,  Asset  Allocation,  Balanced,  Bond,  Capital  Accumulation
[formerly Common Stock], Emerging Growth,  Government Securities,  Growth, Money
Market and World Divisions) as of December 31, 1997, and the related  statements
of operations for the year then ended, and changes in net assets for each of the
two  years  in the  period  then  ended.  These  financial  statements  are  the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of December 31, 1997, by correspondence with
the transfer agent. An audit also includes  assessing the accounting  principles
used and  significant  estimates made by  management,  as well as evaluating the
overall financial statement  presentation.  We believe that our audits provide a
reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects, the financial position of Principal Mutual Life Insurance
Company  Separate  Account  B at  December  31,  1997,  and the  results  of its
operations  for the year then ended,  and the changes in its net assets for each
of the two years in the period then ended, in conformity with generally accepted
accounting principles.

6. Year 2000 Issues (Unaudited)

Like  other  investment   funds,   financial  and  business   organizations  and
individuals around the world,  Separate Account B could be adversely affected if
the computer systems used by Principal Mutual and other service providers do not
properly process and calculate date-related  information and data from and after
January 1, 2000. In 1996,  Principal Mutual completed its assessment of the Year
2000 impact on its systems,  procedures,  customers and business  processes.  At
December 31, 1997, management estimates that approximately 95% of the identified
modifications  have been  completed for its Year 2000 project.  System  testing,
using an isolated test environment,  will begin early in 1998.  Ultimate project
completion is targeted for early 1999, which is prior to any anticipated  impact
on Principal Mutual operations.

The date on which  Principal  Mutual  believes  it will  complete  the Year 2000
modifications  are based on  management's  best  estimates,  which were  derived
utilizing  numerous   assumptions  of  future  events.   Principal  Mutual  also
recognizes there are outside  influences and  dependencies  relative to its Year
2000 effort, over which it has little or no control.  However,  Principal Mutual
is putting effort into ensuring these  considerations  will have minimal impact.
These would include the continued availability of certain resources, third-party
modification  plans and many other factors.  However,  there can be no guarantee
that these estimates will be achieved and actual results could differ from those
anticipated.

                         Report of Independent Auditors







The Board of Directors
Principal Mutual Life Insurance Company

We have audited the accompanying  consolidated  statements of financial position
of The  Principal  Financial  Group(R) (the Company) as of December 31, 1997 and
1996, and the related  consolidated  statements of  operations,  equity and cash
flows for each of the three years in the period ended  December 31, 1997.  These
financial  statements are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

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

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the  consolidated  financial  position of The Principal
Financial  Group(R) at December 31, 1997 and 1996, and the consolidated  results
of its  operations  and its cash flows for each of the three years in the period
ended  December  31,  1997 in  conformity  with  generally  accepted  accounting
principles.

                   Notes to Consolidated Financial Statements

                                December 31, 1997


1.  Nature of Operations and Significant Accounting Policies

Description of Business

The Principal  Financial  Group(R) (the Company),  comprised of Principal Mutual
Life Insurance Company (Principal Mutual) and its subsidiaries, is a diversified
financial services  organization engaged in the marketing and management of life
insurance,  annuity,  health, pension and other financial products and services,
primarily in the United States.

Pending Reorganization

On September 18, 1997, the board of directors  adopted a Plan of  Reorganization
whereby  Principal  Mutual  will form a new  mutual  insurance  holding  company
(Principal Mutual Holding Company) and convert to a stock life insurance company
(Principal  Life  Insurance  Company).  All  of the  shares  of  Principal  Life
Insurance  Company will be issued  initially to Principal Mutual Holding Company
through  two  newly  formed  intermediate  holding  companies,  and there are no
current  plans to offer the stock of  Principal  Life  Insurance  Company or its
parent companies to third parties.  The reorganization will not become effective
unless approved by policyowners and regulatory  authorities.  The reorganization
itself will not have a material financial impact on the Company.

Basis of Presentation

The  accompanying  consolidated  financial  statements  of the  Company  and its
majority-owned  subsidiaries  have been  prepared in conformity  with  generally
accepted  accounting  principles (GAAP).  Less than  majority-owned  entities in
which the Company has at least a 20%  interest  are reported on the equity basis
in the consolidated  statements of financial position as other investments.  All
significant intercompany accounts and transactions have been eliminated.

Total assets of the unconsolidated entities amounted to $1.1 billion at December
31, 1997 and $1.5  billion at December 31, 1996,  and total  revenues  were $294
million in 1997,  $349  million in 1996 and $320  million in 1995.  During 1997,
1996 and 1995, the Company included $19 million,  $(3) million and $(9) million,
respectively,  in net  investment  income  representing  the Company's  share of
current year net income (losses) of the unconsolidated entities.

Use of Estimates in the Preparation of Financial Statements

The  preparation  of  the  Company's   consolidated   financial  statements  and
accompanying  notes requires  management to make estimates and assumptions  that
affect the amounts reported and disclosed. These estimates and assumptions could
change in the future as more information  becomes known,  which could impact the
amounts  reported and disclosed in the  consolidated  financial  statements  and
accompanying notes.

1.  Nature of Operations and Significant Accounting Policies (continued)

Significant Risks

The following is a description of the most significant risks facing  diversified
financial service organizations and how the Company mitigates those risks:

Legal or  regulatory  risk is the risk that  changes in the legal or  regulatory
environment  in which an insurer  operates will create  additional  expenses not
anticipated by the insurer in pricing its products.  The Company  mitigates this
risk by offering a wide range of products and  operating  throughout  the United
States  and the world,  thus  reducing  its  exposure  to any single  product or
jurisdiction,  and also by employing  underwriting  practices which identify and
minimize the adverse impact of this risk.

Credit  risk is the risk that  issuers  of  securities  owned by the  Company or
borrowers  through  mortgage  loans on real  estate  will  default or that other
parties that owe the Company  money,  will not pay. The Company  minimizes  this
risk by adhering to a conservative  investment  strategy,  by maintaining  sound
credit  and  collection  policies  and  by  providing  for  any  amounts  deemed
uncollectible.

Interest  rate risk is the risk that  interest  rates  will  change  and cause a
decrease  in the value of the  Company's  investments.  This change in rates may
also cause certain  interest-sensitive  products to become  uncompetitive or may
cause  disintermediation.  The Company  mitigates this risk by charging fees for
policyowners'  contract  terminations,  by offering  products that transfer this
risk to the purchaser  and by  attempting to match the maturity  schedule of its
assets  with  the  expected  payout  of  its  liabilities.  To the  extent  that
liabilities  come due more quickly than assets mature,  an insurer would have to
borrow funds or sell assets prior to maturity and  potentially  recognize a gain
or loss.

Cash and Cash Equivalents

Cash and cash  equivalents  include cash on hand,  money market  instruments and
other debt issues with a maturity date of three months or less when purchased.

Investments

Investments in debt and equity  securities are classified as  available-for-sale
and,  accordingly,  are carried at fair value. (See Note 10 for policies related
to the determination of fair value.) The cost of debt securities is adjusted for
amortization  of premiums  and accrual of  discounts,  both  computed  using the
interest method. The cost of debt and equity securities is adjusted for declines
in value that are other  than  temporary.  For the  loan-backed  and  structured
securities included in the bond portfolio, the Company recognizes income using a
constant  effective  yield  based  on  currently   anticipated   prepayments  as
determined  by  broker-dealer  surveys or internal  estimates  and the estimated
lives of the securities.

             Notes to Consolidated Financial Statements (continued)




1.  Nature of Operations and Significant Accounting Policies (continued)

Investment real estate is reported at cost less accumulated  depreciation.  Such
real estate is carried net of valuation  allowances.  Valuation  allowances  are
established when indicators of impairment are present and the undiscounted  cash
flows to be generated by the real estate fall below carrying amounts. Properties
acquired through loan foreclosures are recorded at fair market value at the time
of foreclosure or receipt of deed in lieu of  foreclosure.  This becomes the new
cost basis of the real  estate and is  subject  to  further  potential  carrying
amount   reductions  as  a  result  of  depreciation  and  quarterly   valuation
determinations.  Changes in the  valuation  allowance are charged or credited to
net investment income.  Depreciation  expense is computed primarily on the basis
of accelerated and straight-line  methods over the estimated useful lives of the
assets.  Real estate  expected to be disposed is carried at the lower of cost or
fair value, less cost to sell.

Commercial  and  residential  mortgage  loans are reported at cost  adjusted for
amortization  of premiums and accrual of discounts,  computed using the interest
method, and net of valuation allowances. Any changes in the valuation allowances
are reported as realized gains  (losses) on  investments.  The Company  measures
impairment based upon the present value of expected cash flows discounted at the
loan's effective  interest rate. If foreclosure is probable,  the measurement of
impairment is based upon the fair value of the collateral.

Net realized  capital gains and losses on investments  are determined  using the
specific identification basis.

Policy loans and other investments are primarily reported at cost.

Futures and Forward Contracts and Interest Rate and Equity Swaps (Derivatives)

The Company uses financial futures contracts,  forward purchase  commitments and
interest rate swaps to hedge risks  associated  with interest rate  fluctuations
and has used equity swaps to hedge risks associated with market  fluctuations of
certain  unaffiliated  common stocks.  Realized capital gains and losses on both
those contracts that hedge risks associated with interest rate  fluctuations and
equity swaps are recognized in the period incurred.

Contractholder and Policyowner Liabilities

Contractholder and policyowner liabilities  (contractholder funds, future policy
benefits and claims and other policyowner funds) include reserves for investment
contracts and reserves for universal life,  limited payment,  participating  and
traditional life insurance policies.  Investment  contracts are contractholders'
funds on deposit with the Company and generally include reserves for pension and
annuity contracts.  Reserves on investment contracts are equal to the cumulative
deposits less any applicable charges plus credited interest.

             Notes to Consolidated Financial Statements (continued)




1.  Nature of Operations and Significant Accounting Policies (continued)

Reserves for universal life insurance contracts are equal to cumulative premiums
less charges plus credited  interest which  represents the account balances that
accrue to the benefit of the policyowners.  Reserves for non-participating  term
life insurance  contracts are computed on a basis of assumed  investment  yield,
mortality,  morbidity and expenses, including a provision for adverse deviation,
which  generally  vary by plan,  year of issue and policy  duration.  Investment
yield is based on the Company's experience.  Mortality, morbidity and withdrawal
rate  assumptions  are based on experience  of the Company and are  periodically
reviewed against both industry standards and experience.

Reserves for participating  life insurance  contracts are based on the net level
premium reserve for death and endowment policy benefits.  This net level premium
reserve is calculated  based on dividend fund interest rate and mortality  rates
guaranteed in calculating the cash surrender values described in the contract.

Some of the Company's  policies and contracts require payment of fees in advance
for services that will be rendered over the estimated  lives of the policies and
contracts.  These  payments are  established as unearned  revenue  reserves upon
receipt and included in other policyowner  funds in the consolidated  statements
of  financial  position.  These  unearned  revenue  reserves  are  amortized  to
operations over the estimated lives of these policies and contracts.

The  liability  for unpaid  accident  and health  claims is an  estimate  of the
ultimate  net cost of  reported  and  unreported  losses not yet  settled.  This
liability  is estimated  using  actuarial  analyses and case basis  evaluations.
Although  considerable  variability is inherent in such  estimates,  the Company
believes that the liability for unpaid claims is adequate.  These  estimates are
continually  reviewed and, as adjustments to this  liability  become  necessary,
such adjustments are reflected in current operations.

Recognition of Premiums, Fees and Benefits

Traditional individual life and health insurance products include those products
with fixed and  guaranteed  premiums and benefits,  and consist  principally  of
whole life and term life insurance policies and certain immediate annuities with
life  contingencies.  Premiums  from these  products are  recognized  as premium
revenue when due.

Group life and health  insurance  premiums  are  generally  recorded  as premium
revenue over the term of the coverage.  Some group  contracts allow for premiums
to be  adjusted to reflect  emerging  experience.  Such  adjusted  premiums  are
recognized in the period that the related experience emerges. Fees for contracts
providing claim  processing or other  administrative  services are recorded over
the period the service is provided.

Related  policy  benefits and expenses for  individual and group life and health
insurance  products  are  associated  with  earned  premiums  and  result in the
recognition of profits over the expected lives of the policies and contracts.

             Notes to Consolidated Financial Statements (continued)




1.  Nature of Operations and Significant Accounting Policies (continued)

Universal  life-type  policies are insurance  contracts  with terms that are not
fixed and  guaranteed.  Amounts  received as payments for such contracts are not
reported  as  premium  revenues.  Revenues  for  universal  life-type  insurance
contracts consist of policy charges for the cost of insurance, policy initiation
and  administration,  surrender  charges and other fees that have been  assessed
against policy account  values.  Policy  benefits and claims that are charged to
expense  include  interest  credited to contracts and benefit claims incurred in
the period in excess of related policy account balances.

Investment   contracts  do  not  subject  the  Company  to  risks  arising  from
policyowner  mortality  or  morbidity,   and  consist  primarily  of  Guaranteed
Investment Contracts (GICs) and certain deferred annuities.  Amounts received as
payments  for  investment  contracts  are  established  as  investment  contract
liability  balances  and are not  reported  as premium  revenues.  Revenues  for
investment  contracts  consist of  investment  income and policy  administration
charges.  Investment  contract  benefits  that are  charged to  expense  include
benefit claims incurred in the period in excess of related  investment  contract
liability  balances  and  interest  credited to  investment  contract  liability
balances.

Deferred Acquisition Costs

Commissions and other costs  (underwriting,  issuance and agency  expenses) that
vary  with and are  primarily  related  to the  acquisition  of new and  renewal
insurance  policies and  investment  contract  business are  capitalized  to the
extent  recoverable.  Acquisition  costs that are not deferrable and maintenance
costs are charged to operations as incurred.

Deferred  acquisition  costs for  universal  life-type  insurance  contracts and
participating  life  insurance  policies  and  investment  contracts  are  being
amortized  over the lives of the  policies  and  contracts  in  relation  to the
emergence  of estimated  gross profit  margins.  This  amortization  is adjusted
retrospectively when estimates of current or future gross profits and margins to
be realized  from a group of products and  contracts  are revised.  The deferred
acquisition costs of  non-participating  term life insurance  policies are being
amortized  over  the  premium-paying   period  of  the  related  policies  using
assumptions consistent with those used in computing policyowner liabilities.

Deferred acquisition costs are subject to recoverability  testing at the time of
policy issue and loss recognition  testing at the end of each accounting period.
Deferred  acquisition  costs  would  be  written  off to the  extent  that it is
determined  that future policy  premiums and  investment  income or gross profit
margins would not be adequate to cover related losses and expenses.

Reinsurance

The Company  enters into  reinsurance  agreements  with other  companies  in the
normal  course of  business.  The  Company may assume  reinsurance  from or cede
reinsurance to other companies.  Reinsurance premiums, expenses,  recoveries and
reserves  related to reinsured  business are accounted  for on bases  consistent
with those used in accounting for the original  policies issued and the terms of
the  reinsurance   contracts,   reported  on  a  gross  basis.  The  Company  is
contingently  liable with respect to reinsurance ceded to other companies in the
event the reinsurer is unable to meet the obligations it has assumed.

1.  Nature of Operations and Significant Accounting Policies (continued)

Guaranty-fund Assessments

Guaranty-fund  assessments are accrued when the Company  receives notice that an
amount is payable to a guaranty  fund.  The Company  also  accrues for  possible
guaranty-fund assessments for which notices have not been received and for which
the Company does not anticipate receiving a premium tax credit.

Separate Accounts

The  separate  account  assets and  liabilities  presented  in the  consolidated
financial  statements  represent  the  fair  market  value  of  funds  that  are
separately  administered  by the Company for contracts with equity,  real estate
and fixed-income  investments.  The separate account contract owner, rather than
the Company,  bears the  investment  risk of these funds.  The separate  account
assets are  legally  segregated  and are not subject to claims that arise out of
any  other   business  of  the   Company.   The  Company   receives  a  fee  for
administrative, maintenance and investment advisory services that is included in
the consolidated  statements of operations.  Deposits, net investment income and
realized and  unrealized  capital gains and losses on the separate  accounts are
not reflected in the consolidated statements of operations.

Income Taxes

The Company  files a  consolidated  income tax return that  includes  all of its
qualifying  subsidiaries and has a policy of allocating  income tax expenses and
benefits to companies in the group based upon pro rata  contribution  of taxable
income or operating  losses.  The Company is taxed at corporate rates on taxable
income based on existing tax laws.  Current income taxes are charged or credited
to operations  based upon amounts  estimated to be payable or  recoverable  as a
result of taxable  operations  for the current year.  Deferred  income taxes are
provided for the tax effect of differences in the financial reporting and income
tax bases of assets and  liabilities  and net  operating  losses  using  enacted
income tax rates and laws.  The effect on deferred  tax assets and  deferred tax
liabilities  of a change in tax rates is  recognized in operations in the period
in which the change is enacted.

Foreign Exchange

The  Company's  foreign  subsidiaries'  statements  of  financial  position  and
operations  are translated at the current  exchange  rates and average  exchange
rates for the year, respectively.  Resulting translation adjustments for foreign
subsidiaries  and certain  other  transactions  are  reported as a component  of
equity.  Other  translation  adjustments for foreign currency  transactions that
affect cash flows are reported in current operations.

Pension and Postretirement Benefits

The Company accounts for its pension benefits and postretirement  benefits other
than pension (medical, life insurance and long-term care) using the full accrual
method.

Property Held for Company Use

Property  held for  Company use  includes  home  office  properties  and related
leasehold  improvements.   Property  held  for  Company  use  is  shown  in  the
consolidated  statements  of  financial  position  at cost less  allowances  for
accumulated  depreciation.  Provisions  for  depreciation  of property  held for
Company  use are  computed  principally  on the  straight-line  method  over the
estimated useful lives of the assets.  Property held for Company use and related
accumulated depreciation are as follows (in millions):

Other Assets

Intangible assets are included in other assets in the consolidated statements of
financial  position.  The cost of  acquired  subsidiaries  in excess of the fair
value of the net assets (i.e.,  goodwill) and other intangible assets (primarily
customer lists and institutional  customer  relationships) have been recorded in
connection  with  acquisitions.  These assets are  amortized on a  straight-line
basis  primarily over 40 years with the exception of assets  acquired after 1995
which are amortized  over ten years.  The carrying  amount of goodwill and other
intangible  assets is reviewed  periodically  for  indicators  of  impairment in
value. Intangible assets and related accumulated amortization are as follows (in
millions):

Mortgage  servicing rights of $432 million and $272 million at December 31, 1997
and  1996,  respectively,  are  included  in other  assets  in the  consolidated
statements  of  financial  position  and  represent  the cost of  purchasing  or
originating the right to service mortgage loans. These costs are capitalized and
amortized to operations  over the estimated  remaining  lives of the  underlying
loans using the interest method and taking into account  appropriate  prepayment
assumptions. Capitalized mortgage servicing rights are periodically assessed for
impairment,  which is  recognized in the  consolidated  statements of operations
during the period in which  impairment  occurs by  establishing a  corresponding
valuation allowance.

Other assets are reported primarily at cost.

Reclassifications

Certain  reclassifications  have  been  made to the 1995  and 1996  consolidated
financial statements to conform to the 1997 presentation.

2.  Investments

Under  SFAS No.  115,  Accounting  for  Certain  Investments  in Debt and Equity
Securities,   securities   are  generally   classified  as   available-for-sale,
held-to-maturity,  or  trading.  The  Company  has  classified  its entire  debt
securities  portfolio  as  available-for-sale,  although  it  is  generally  the
Company's  intent to hold these  securities  to  maturity.  The Company has also
classified all equity securities as available-for-sale. Securities classified as
available-for-sale are reported at fair value in the consolidated  statements of
financial  position with the related unrealized holding gains and losses on such
available-for-sale  securities  reported as a separate component of equity after
adjustments for related changes in deferred acquisition costs,  unearned revenue
reserves and deferred income taxes.

The cost,  gross  unrealized  gains and losses and fair value of debt and equity
securities  available-for-sale  as of December 31, 1997 and 1996, are as follows

Proceeds from sales of  investments  (excluding  call and maturity  proceeds) in
debt securities  were $5.0 billion,  $7.8 billion and $6.5 billion in 1997, 1996
and 1995, respectively.  Gross gains of $48 million, $76 million and $93 million
and gross losses of $43 million,  $69 million and $35 million in 1997,  1996 and
1995, respectively, were realized on those sales.

Of the  1997,  1996 and 1995  proceeds,  $4.0  billion,  $7.2  billion  and $6.1
billion,  respectively,  relates  to sales of  mortgage-backed  securities.  The
Company actively  manages its  mortgage-backed  securities  portfolio to control
prepayment  risk.  Gross gains of $29  million,  $64 million and $66 million and
gross losses of $10 million, $53 million and $17 million in 1997, 1996 and 1995,
respectively,  were realized on sales of mortgage-backed securities. At December
31,  1997,  the Company had security  purchases  payable  totaling  $266 million
relating to the purchases of mortgage-backed securities at forward dates.

Prior to 1996, the Company  entered into  short-term  equity swap  agreements to
mitigate  its  exposure  to  declines  in the  value  of about  one-half  of its
marketable  common stock  portfolio.  Under the  agreements,  the return on that
portion of the  Company's  marketable  common stock  portfolio was swapped for a
fixed short-term interest rate. The equity swaps were terminated during 1996 and
a  realized  loss  of $81  million  recorded.  Common  stocks  of  $633  million
associated  with these  equity  swaps were sold  during  1996 and a gain of $402
million recorded, resulting in a net realized gain of $321 million.

Mortgage  loans on real estate are considered  impaired  when,  based on current
information  and  events,  it is  probable  that the  Company  will be unable to
collect all amounts due according to  contractual  terms of the loan  agreement.
When the Company  determines  that a loan is impaired,  a provision  for loss is
established for the difference  between the carrying amount of the mortgage loan
and the estimated value. Estimated value is based on either the present value of
the expected future cash flows discounted at the loan's effective interest rate,
the  loan's  observable  market  price  or fair  value  of the  collateral.  The
provision for losses is reported as realized gains (losses) on investments.

Mortgage loans deemed to be uncollectible  are charged against the allowance for
losses and subsequent  recoveries are credited to the allowance for losses.  The
allowance for losses is maintained at a level believed adequate by management to
absorb estimated probable credit losses. Management's periodic evaluation of the
adequacy of the allowance  for losses is based on the  Company's  past loan loss
experience,  known and inherent risks in the portfolio,  adverse situations that
may  affect  the  borrower's  ability  to  repay,  the  estimated  value  of the
underlying  collateral,  composition  of the loan  portfolio,  current  economic
conditions and other relevant factors.  The evaluation is inherently  subjective
as it requires  estimating  the amounts and timing of future cash flows expected
to be received on impaired loans that may change.

A summary of the changes in the mortgage loan allowance for losses is as follows
(in millions):

The corporate  private  placement  bond  portfolio is  diversified by issuer and
industry.  Restrictive  bond  covenants are monitored by the Company to regulate
the activities of issuers and control their leveraging capabilities.

The Company was servicing approximately 371,000 and 328,000 residential mortgage
loans with aggregate principal balances of approximately $29.1 billion and $24.4
billion at December 31, 1997 and 1996,  respectively.  In connection  with these
mortgage  servicing  activities,  the  Company  held  funds in trust for  others
totaling  approximately  $210  million and $175 million at December 31, 1997 and
1996, respectively.  In connection with its loan administration  activities, the
Company  advances  payments of property  taxes and  insurance  premiums and also
advances  principal and interest  payments to investors in advance of collecting
funds from specific mortgagors.  In addition, the Company makes certain payments
of attorney fees and other costs related to loans in foreclosure.  These amounts
receivable  are  recorded,  at cost,  as  advances on  serviced  loans.  Amounts
advanced  are  considered  in  management's  evaluation  of the  adequacy of the
allowance for loan loss.

Other  investments  include  properties  owned jointly with venture partners and
operated by the  partners.  Joint  ventures in which the Company has an interest
have  mortgage  loans  with the  Company  of $1.2  billion  and $1.4  billion at
December 31, 1997 and 1996, respectively.  The Company is committed to providing
additional  mortgage financing for such joint ventures  aggregating $120 million
at December 31, 1997.

3.  Derivatives Held or Issued for Purposes Other Than Trading

The Company uses exchange-traded  interest rate futures and forward contracts to
hedge against  interest rate risks.  The Company attempts to match the timing of
when interest rates are committed on insurance  products and on new investments.
However,  timing  differences do occur and can expose the Company to fluctuating
interest rates. Interest rate futures and forward contracts are used to minimize
these  risks.  In these  contracts,  the Company is subject to the risk that the
counterparties  will fail to perform and to the risks associated with changes in
the value of the underlying securities; however, such changes in value generally
are  offset by  opposite  changes  in the  value of the  hedged  items.  Futures
contracts  are  marked  to  market  and  settled  daily,   which  minimizes  the
counterparty  risk. The notional  amounts of futures and forward  contracts ($36
million at December 31, 1997,  and $148 million at December 31, 1996)  represent
the extent of the Company's involvement but not the risk of loss.

The  Company  enters  into  interest  rate swaps to  minimize  its  exposure  to
fluctuations in interest rates. The most common use is to modify the duration of
an asset or  portfolio,  a less  common use is to convert a floating  rate asset
into a fixed rate asset. The notional principal amounts of the swaps outstanding
at  December  31,  1997  and  1996,   were  $1,037  million  and  $970  million,
respectively,  and the credit  exposure  at  December  31, 1997 and 1996 was $21
million and $15 million,  respectively. The Company is exposed to credit loss in
the event of nonperformance of the counterparties. This credit risk is minimized
by  purchasing  such  agreements  from  financial   institutions  with  superior
performance  records.  The Company's current credit exposure on swaps is limited
to the value of interest  rate swaps that have become  favorable to the Company.
The average unexpired terms of the swaps were  approximately six years and three
years at December  31, 1997 and 1996,  respectively.  The net amount  payable or
receivable from

interest  rate  swaps is  accrued  as an  adjustment  to  interest  income.  The
Company's  interest rate swap agreements include  cross-default  provisions when
two or more swaps are transacted with a given counterparty.

The Company  enters into currency  exchange swap  agreements to convert  certain
foreign  denominated  fixed rate assets into U.S. dollar  denominated fixed rate
assets  and  eliminate  the  exposure  to future  currency  volatility  on those
securities.  At December  31,  1997,  the Company had various  foreign  currency
exchange agreements with maturities ranging from 1998 to 2018, with an aggregate
notional amount involved of  approximately  $410 million and the credit exposure
was $17 million.  At December 31, 1996, such maturities ranged from 1997 to 2018
with an aggregate  notional  amount of  approximately  $373 million and a credit
exposure  of  $9  million.   The  average   unexpired  term  of  the  swaps  was
approximately seven years at both December 31, 1997 and 1996.

The Company uses  interest  rate floors in hedging a portion of its portfolio of
mortgage  servicing  rights from  prepayment  risk  associated  with  changes in
interest rates. At both December 31, 1997 and 1996, the Company had entered into
interest rate floors with a notional  value of $1.3 billion.  The floors provide
for the receipt of payments when interest rates are below predetermined interest
rate levels.  The  premiums  paid for floors are included in other assets in the
Company's consolidated statements of financial position.

4.  Accident and Health Reserves (continued)

The activity  summary in the  liability  for unpaid  accident and health  claims
shows a decrease of $21 million,  $29 million and $5 million to the December 31,
1996,   1995  and  1994  liability  for  unpaid   accident  and  health  claims,
respectively, arising in prior years. Such liability adjustments, which affected
current  operations  during 1997,  1996 and 1995,  respectively,  resulted  from
developed  claims for prior years being different than were anticipated when the
liabilities  for unpaid  accident and health claims were  originally  estimated.
These trends have been considered in establishing the current year liability for
unpaid accident and health claims.

5.  Debt

The  components  of debt as of December  31, 1997 and  December  31, 1996 are as
follows (in millions):

                                                     December 31

      Total debt                                 $459          $399
                                             =============================

On March 10,  1994,  Principal  Mutual  issued  $300  million of surplus  notes,
including  $200 million due March 1, 2024 at a 7.875%  annual  interest rate and
the remaining  $100 million due March 1, 2044 at an 8% annual  interest rate. No
affiliates of the Company hold any portion of the notes. The discount and direct
costs  associated  with issuing these notes are being  amortized to expense over
their respective  terms using the interest method.  Each payment of interest and
principal on the notes, however, may be made only with the prior approval of the
Commissioner  of Insurance of the State of Iowa (the  Commissioner)  and only to
the extent that Principal  Mutual has sufficient  surplus  earnings to make such
payments. For each of the years ended December 31, 1997, 1996 and 1995, interest
of $24 million was approved by the Commissioner, paid and charged to expense.

Subject to  Commissioner  approval,  the surplus  notes due March 1, 2024 may be
redeemed at Principal Mutual's election on or after March 1, 2004 in whole or in
part at a redemption price of approximately  103.6% of par. The approximate 3.6%
premium is scheduled to gradually  diminish over the following ten years.  These
surplus  notes may then be redeemed on or after March 1, 2014,  at a  redemption
price of 100% of the  principal  amount  plus  interest  accrued  to the date of
redemption.

In addition,  subject to Commissioner  approval, the notes due March 1, 2044 may
be redeemed at Principal  Mutual's  election on or after March 1, 2014, in whole
or in part at a redemption price of approximately 102.3% of par. The approximate
2.3% premium is scheduled to gradually  diminish  over the  following ten years.
These notes may be redeemed on or after March 1, 2024, at a redemption  price of
100% of the principal amount plus interest accrued to the date of redemption.

The  mortgages  and  other  notes  payable  are   financings   for  real  estate
developments.  The Company has obtained  loans with  various  lenders to finance
these developments. Outstanding principal balances as of December 31, 1997 range
from $1 million to $10.7 million per  development  with interest rates generally
ranging  from 6.6% to 8.0%.  Outstanding  principal  balances as of December 31,
1996 range from $1 million to $9 million per  development  with  interest  rates
generally ranging from 5.9% to 7.7%.

millions):

   1998                                                      $  79

                                                           ==========

Cash paid for interest for 1997, 1996 and 1995 was $63 million,  $52 million and
$50 million, respectively.

The  Company  issues  commercial  paper  periodically  to  meet  its  short-term
financing needs and also has credit  facilities with various banks.  The Company
had  outstanding  credit  borrowings of $225 million and $15 million at December
31, 1997 and 1996,  respectively,  and other outstanding borrowings from certain
financing  transactions of $154 million at December 31, 1996. These  outstanding
borrowings are included in other  liabilities in the consolidated  statements of
financial position.


6.  Income Taxes

The Company's income tax expense (benefit) is as follows (in millions):

                                      Year ended December 31
                                 1997          1996          1995
                               ----------------------------------------
   Current income taxes:
     Federal                      $144          $145          $104
     State and foreign               3            (1)            5
     Realized capital gains         11           210            41
                               ----------------------------------------
   Total current income taxes      158           354           150
   Deferred income taxes            83           (50)           57
                               ========================================
   Total income taxes             $241          $304          $207
                               ========================================

The Company's provision for income taxes may not have the customary relationship
of taxes to income. Differences between the prevailing corporate income tax rate
of 35% times the pre-tax income and the Company's  effective tax rate on pre-tax
income are generally due to inherent  differences  between  income for financial
reporting  purposes  and  income  for tax  purposes,  and the  establishment  of
adequate  provisions  for any  challenges of the tax filings and tax payments to
the various taxing jurisdictions.

6.  Income Taxes (continued)

The Internal  Revenue  Service (the  Service) has completed  examination  of the
consolidated  federal  income tax  returns of  Principal  Mutual and  affiliated
companies through 1992. The Service is currently  completing its examination for
the years 1993 and 1994. The Company  believes that there are adequate  defenses
against or sufficient provisions for any challenges.

The  Company's  deferred  income tax  liabilities  and assets are as follows (in
millions):

                                                 December 31
                                             1997           1996
                                         -----------------------------

   Deferred income tax liabilities           $1,259        $1,110
   Deferred income tax assets                   456           487
                                         =============================
   Deferred income taxes, net               $   803       $   623
                                         =============================

The Company's  significant  deferred income tax liabilities and assets relate to
unrealized  gains on  available-for-sale  debt and equity  securities,  deferred
acquisition  costs,  unrealized  joint venture  losses,  policy  liabilities and
accruals and contractholder  funds and claims,  policyowner  dividend liability,
prepaid  postretirement  benefits other than pension,  other investment  related
items and  premiums  and fees  receivable.  No  valuation  allowances  have been
recognized against deferred tax assets.

The Company  has not  recognized  deferred  taxes  related to the  undistributed
earnings of certain foreign  subsidiaries that are considered to be indefinitely
reinvested  because the Company does not expect to repatriate these earnings.  A
tax liability will be recognized when the Company expects  distribution of those
earnings in the form of dividends, sale of the investment or otherwise.

Cash paid for income taxes in 1997, 1996 and 1995 was $143 million, $285 million
and $99 million, respectively.


7.  Employee and Agent Benefits

The Company has defined benefit pension plans covering  substantially all of its
employees and certain  agents.  The  employees  and agents are  generally  first
eligible for the pension plans when they reach age 21. The pension  benefits are
based on the years of service and  generally the  employee's or agent's  average
annual  compensation  during the last five years of employment.  Partial benefit
accrual  of  pension  benefits  is  recognized  from  first   eligibility  until
retirement based on attained service divided by potential service to age 65 with
a minimum of 35 years of potential service.  The Company's policy is to fund the
cost of providing  pension  benefits in the years that the  employees and agents
are providing service to the Company. The Company's funding policy is to deposit
the actuarial  normal cost and any change in unfunded  accrued  liability over a
30-year period as a percentage of compensation.

The  weighted-average  assumed  discount rate used in determining  the projected
benefit  obligation  was 7.25% at both  December  31,  1997 and 1996,  and 7% at
December  31,  1995.  Some of the trusts  holding the plan assets are subject to
income taxes at a 35% tax rate while others are not subject to income taxes. For
1997, 1996 and 1995, the expected  long-term rates of return on plan assets were
approximately  6% (after  estimated  income  taxes) for those trusts  subject to
income taxes and approximately 9.5% for those trusts not subject to income taxes
in each year. The assumed rate of increase in future  compensation levels varies
by age for both the qualified and non-qualified pension plans.

7.  Employee and Agent Benefits (continued)

In  addition,  the  Company has defined  contribution  plans that are  generally
available to all employees and agents who are age 21 or older and have completed
one year of service.  Eligible  participants  may  contribute up to 15% of their
compensation,  to a  maximum  of $9,500  annually  to the plans in both 1997 and
1996, and $9,240 in 1995. The Company matches the participant's  contribution at
a 50%  contribution  rate  up to a  maximum  Company  contribution  of 2% of the
participant's  compensation.  The Company  contributed  $15 million in 1997, $13
million in 1996 and $11 million in 1995 to these defined contribution plans.

The Company also provides certain health care, life insurance and long-term care
benefits for retired  employees.  Substantially all employees are first eligible
for these postretirement  benefits when they reach age 57 and have completed ten
years of service with the Company. Partial benefit accrual of these health, life
and long-term care benefits is recognized from the employee's date of hire until
retirement based on attained service divided by potential service to age 65 with
a minimum of 35 years of potential service.  The Company's policy is to fund the
cost of providing retiree benefits in the years that the employees are providing
service to the Company. The Company's funding policy is to deposit the actuarial
normal cost and an accrued  liability  over a 30-year  period as a percentage of
compensation.

The  weighted-average  assumed discount rate used in determining the accumulated
postretirement  benefit obligation was 7.25% at both December 31, 1997 and 1996,
and 7% at  December  31,  1995.  Some of the trusts  holding the plan assets are
subject to income taxes at a 35% tax rate while others are not subject to income
taxes.  For 1997, 1996 and 1995, the expected  long-term rates of return on plan
assets were  approximately  5% (after  estimated  income taxes) for those trusts
subject to income  taxes and  approximately  8% for those  trusts not subject to
income taxes in each year.  These rates of return on plan assets vary by benefit
type and employee group.

The  assumed  health  care cost trend  rate used in  measuring  the  accumulated
postretirement  benefit  obligations  starts at 9% in 1997,  declines to 8.5% in
2002 and then  declines  to an ultimate  rate of 6% in 2030.  If the health care
cost trend rate  assumptions  were increased by 1% in each year, the accumulated
postretirement  benefits  obligation  for health  plans as of December  31, 1997
would increase by 27.7% ($45 million). The effect of this 1% increase would also
increase the aggregate of the service cost and interest  cost  components of the
net  periodic  postretirement  benefit  cost of health  plans for the year ended
December 31, 1997 by 24% ($6 million).


8.  Reinsurance

Reinsurance  contracts  do not  relieve  the  Company  from its  obligations  to
policyowners.  Failure of reinsurers to honor their  obligations could result in
losses to the Company. The Company evaluates the financial strength of potential
reinsurers  and  continually   monitors  the  financial   condition  of  present
reinsurers. The Company also monitors concentrations of credit risk arising from
similar  geographic  regions,  activities  or  economic  characteristics  of the
reinsurers  to minimize  its  exposure  to  significant  losses  from  reinsurer
insolvencies.

The Company,  as a lessee,  leases office space,  data processing  equipment and
office furniture and equipment under various  operating  leases.  Rental expense
for all  operating  leases  totaled $73  million in both 1997 and 1996,  and $69

The Company is a defendant in various legal actions arising in the normal course
of its investment and insurance  operations.  In the opinion of management,  any
losses  resulting  from the resolution of such actions would not have a material
effect on the Company's consolidated financial statements.

The Company is also subject to insurance  guarantee  laws in the states in which
it writes  business.  These  laws  provide  for  assessments  against  insurance
companies  for the  benefit  of  policyowners  and  claimants  in the  event  of
insolvency  of other  insurance  companies.  The  assessments  may be  partially
recovered  through  a  reduction  in future  premium  taxes in some  states.  At
December  31,  1997  and  1996,   approximately  $6  million  and  $15  million,
respectively,  is accrued in other liabilities in the consolidated statements of
financial  position for possible  guarantee fund  assessments  for which notices
have not been received and the Company does not  anticipate  receiving a premium
tax credit.


10.  Fair Value of Financial Instruments

The following  discussion  describes the methods and assumptions utilized by the
Company in estimating  its fair value  disclosures  for  financial  instruments.
Certain financial instruments,  particularly  policyowner liabilities other than
investment   contracts,   are   excluded   from  these  fair  value   disclosure
requirements. The techniques utilized in estimating the fair values of financial
instruments are affected by the assumptions used,  including  discount rates and
estimates  of the  amount  and  timing  of future  cash  flows.  Care  should be
exercised in deriving  conclusions  about the Company's  business,  its value or
financial position based on the fair value information of financial  instruments
presented  below.  The  estimates  shown are not  necessarily  indicative of the
amounts that would be realized in a one-time,  current market exchange of all of
the Company's financial instruments.

10.  Fair Value of Financial Instruments (continued)

The Company defines fair value as the quoted market prices for those instruments
that are actively  traded in  financial  markets.  In cases where quoted  market
prices are not available, fair values are estimated using present value or other
valuation  techniques.  The fair value estimates are made at a specific point in
time,  based on available  market  information and judgments about the financial
instrument,  including estimates of timing, amount of expected future cash flows
and the credit  standing of  counterparties.  Such estimates do not consider the
tax impact of the realization of unrealized gains or losses.  In many cases, the
fair value  estimates  cannot be  substantiated  by  comparison  to  independent
markets.  In  addition,  the  disclosed  fair value may not be  realized  in the
immediate settlement of the financial instrument.

Fair values of public debt and equity  securities  have been  determined  by the
Company from public quotations, when available. Private placement securities and
other debt and equity  securities are valued by  discounting  the expected total
cash flows.  Market rates used are  applicable to the yield,  credit quality and
average maturity of each security.

Fair values of  commercial  mortgage  loans are  determined by  discounting  the
expected  total cash flows using market rates that are  applicable to the yield,
credit quality and maturity of each loan.  Fair values of  residential  mortgage
loans are  determined by a pricing and  servicing  model using market rates that
are applicable to the yield, rate structure,  credit quality,  size and maturity
of each loan.

The fair values for assets classified as policy loans, other  investments,  cash
and  cash  equivalents  and  accrued   investment  income  in  the  accompanying
consolidated   statements  of  financial  position  approximate  their  carrying
amounts.

The fair values of the Company's  reserves and liabilities  for  investment-type
insurance contracts  (insurance,  annuity and other policy contracts that do not
involve  significant  mortality or morbidity risk and that are only a portion of
the  policyowner   liabilities  appearing  in  the  consolidated  statements  of
financial  position) are estimated using discounted cash flow analyses (based on
current  interest  rates being  offered for similar  contracts  with  maturities
consistent with those remaining for the investment-type contracts being valued).
The fair values for the Company's  insurance contracts  (insurance,  annuity and
other policy contracts that do involve significant mortality or morbidity risk),
other than  investment-type  contracts,  are not required to be  disclosed.  The
Company does consider,  however,  the various  insurance and investment risks in
choosing investments for both insurance and investment-type contracts.

Fair values for debt issues are estimated  using  discounted  cash flow analysis
based  on  the  Company's  incremental  borrowing  rate  for  similar  borrowing
arrangements.

11.  Statutory Insurance Financial Information

Principal  Mutual,  the  largest  member of The  Principal  Financial  Group(R),
prepares  statutory  financial  statements  in  accordance  with the  accounting
practices prescribed or permitted by the Insurance Division of the Department of
Commerce  of the  State of Iowa.  Currently  "prescribed"  statutory  accounting
practices  include a variety of  publications  of the  National  Association  of
Insurance   Commissioners  as  well  as  state  laws,  regulations  and  general
administrative  rules.  "Permitted" statutory accounting practices encompass all
accounting  practices not so prescribed.  The impact of any permitted accounting
practices on statutory surplus is not material. The accounting practices used to
prepare statutory financial  statements for regulatory filings differ in certain
instances from GAAP.  Prescribed or permitted statutory accounting practices are
used by state insurance departments to regulate the Company.

The  NAIC  is  in  the  process  of  codifying  statutory  accounting  practices
(Codification), the result of which is expected to constitute the only source of
"prescribed" statutory accounting practices. Accordingly, that project, which is
expected to be approved by the NAIC in 1998, will likely change, to some extent,
prescribed  statutory  accounting  practices  and may  result in  changes to the
accounting  practices that Principal Mutual uses to prepare its  statutory-basis
financial  statements.  Codification will require adoption by the various states
before it becomes the  prescribed  statutory  basis of accounting  for insurance
companies  domiciled within those states.  The impact on Principal Mutual's 1997
statutory surplus has not yet been determined at this time.

11.  Statutory Insurance Financial Information (continued)

Life/Health  insurance companies are subject to certain risk-based capital (RBC)
requirements as specified by the NAIC. Under those  requirements,  the amount of
capital and  surplus  maintained  by a  life/health  insurance  company is to be
determined  based on the various  risk  factors  related to it. At December  31,
1997, Principal Mutual meets the RBC requirements.

The  following  summary  reconciles  the assets and equity at December 31, 1997,
1996 and 1995,  and net income for the years ended  December 31, 1997,  1996 and
1995, in accordance with statutory reporting  practices  prescribed or permitted
by the  Insurance  Division of the  Department  of Commerce of the State of Iowa
(Principal Mutual only) with that reported in these  consolidated GAAP financial
statements (in millions):

12.  Business Acquisitions and Disposition

During  1997,  various  acquisitions  were  made  by  certain  of the  Company's
subsidiaries at purchase prices aggregating $101 million.  The acquisitions were
all accounted for using the purchase method and the results of operations of the
acquired  businesses  have been  included  in the  financial  statements  of the
subsidiaries from the dates of acquisition.  Such  acquisitions  increased total
assets at December 31, 1997 and total 1997 revenue of the  subsidiaries  by $459
million and $88 million, respectively.

During 1997, the Company  terminated a portion of its group medical business and
helped   insureds   find   replacement   coverage.   The  Company  has  retained
responsibility  for the payment of claims incurred on this business prior to the
effective date of the  termination  and has included an estimate of the ultimate
liability for these claims in its financial statements.  Annual premiums related
to this business were approximately $380 million at date of transfer.

13.  Subsequent Events

On November 3, 1997,  the  Company  entered  into a  definitive  agreement  with
Coventry  Corporation to effectively  merge  substantially  all of the Company's
managed  health  care  operations  with  Coventry   Corporation,   a  previously
unaffiliated  managed care company.  The closing of the definitive  agreement is
subject to regulatory  approvals and various other conditions.  The Company will
own 40% of a resulting new company,  Coventry Health Care,  Inc.,  which will be
publicly  traded,  and  will  recognize  no gain  or  loss  on the  transaction.
Subsequent  to  closing,  which is expected  in the first  quarter of 1998,  the
Company  will  account  for its  investment  in the new entity  using the equity
method and will no longer consolidate the

transferred  businesses.  Total assets at December 31, 1997,  and total revenues
and pretax loss for the year then ended, were approximately  $419 million,  $883
million and $(26) million,  respectively,  for the transferred  businesses.  The
Company  also intends to enter into a  reinsurance  agreement on January 1, 2000
whereby  Coventry  Health and Life Insurance  Company,  a subsidiary of Coventry
Corporation,  will  reinsure  a  portion  of  the  Company's  traditional  group
indemnity  health  insurance  business in  overlapping  markets (1997 revenue of
approximately $550 million) at that time.

In December 1997, the Company signed a definitive  agreement with EVEREN Capital
Corporation to sell Principal Securities Holding Corporation and its subsidiary,
Principal Financial Securities,  Inc., an investment banking and stock brokerage
firm for $75 million.  The  transaction,  which  required  regulatory  approval,
closed in January 1998. Total assets of Principal Securities Holding Corporation
at  December  31,  1997,  and total  revenues  and pretax loss for the year then
ended,  were  approximately  $91  million,   $144  million  and  $(10)  million,
respectively.


14.  Year 2000 Issues (Unaudited)

In 1995, the Company began  investigating  the potential impact of the year 2000
on its systems, procedures, customers and business processes. Some changes began
immediately,  while others waited for an assessment  that was completed in 1996.
The Year 2000  assessment  provided  information  used to determine  what system
components  must be changed or replaced to minimize  the impact of the  calendar
change  from 1999 to 2000.  The goal of the  Company is to have its  systems and
procedures function correctly, regardless of the current date on the calendar.

The Company will  continue to use  internal  and  external  resources to modify,
replace,   and  test  the  Year   2000   modifications.   Management   estimates
approximately  95% of the identified  modifications  have been completed for its
Year 2000 project.  System  testing,  using an isolated test  environment,  will
begin early in 1998.  Ultimate  project  completion  is targeted for early 1999,
which is prior to any anticipated impact on Company  operations.  The total cost
for the project is estimated to be $20 million, with the costs being expensed as
incurred until completion.

The costs of the  project  and the date on which the  Company  believes  it will
complete the Year 2000  modifications  are based on management's best estimates,
which were derived utilizing numerous  assumptions of future events. The Company
also recognizes there are outside  influences and  dependencies  relative to its
Year 2000 effort, over which it has little or no control.  However,  the Company
is putting effort into ensuring these  considerations  will have minimal impact.
These would include the continued availability of certain resources, third-party
modification  plans and many other factors.  However,  there can be no guarantee
that these estimates will be achieved and actual results could differ from those
anticipated.
