     The group variable annuity contracts described in this prospectus provide:
 
     - tax deferred annuities for employees of public schools and certain
       tax-exempt organizations; and
 
     - retirement plans for self-employed individuals and their eligible
       employees.
 
     You may participate in these contracts by investing in Continental
Assurance Company Separate Account (B), a separate account created by
Continental Assurance Company. We will place all purchase payments that you make
under a contract, after the deduction of initial charges, in Separate
Account (B).
 
     Separate Account (B) invests its assets primarily in common stocks and
securities convertible into common stocks. The primary investment objective of
the separate account is the growth of capital in relation to the growth of the
economy and the changing value of the dollar. Current investment income is only
a secondary objective. Continental Assurance Company acts as investment adviser
to, and as principal underwriter for, Separate Account (B).
 
     Group variable annuity contracts involve risks, including possible loss of
principal, and are not a deposit or obligation of, or guaranteed or endorsed by,
any bank or depository institution. The contracts are not federally insured by
the Federal Deposit Insurance Corporation, The Federal Reserve Board, or any
other agency.
 
     Please read this prospectus carefully before investing and keep it for
future reference. It contains important information about the separate account
and the group variable annuity contracts that you need before purchasing a
contract.
 
     To learn more about Separate Account (B) and the contracts offered by this
prospectus, you can obtain a copy of the Statement of Additional Information
dated April 30, 1999. The Statement of Additional Information has been filed

GROUP VARIABLE ANNUITY CONTRACTS
 
     The Contracts offered by this prospectus are designed to provide annuity
payments under two types of plans: 403(b) Plans and HR-10 Plans.
 
     -  Contracts for 403(b) Plans are issued to annuity purchase plans adopted
        by public school systems and certain tax-exempt organizations under
        Section 403(b) of the Internal Revenue Code.
 
     -  Contracts for HR-10 Plans are issued to self-employed individuals for
        themselves and their employees, or to a trustee for the benefit of such
        persons and to associations of self-employed persons for the benefit of
        participating members.
 
     We currently offer three types of Contracts for 403(b) Plans: (a) the
403(b) Plan Contract for the Joint Retirement Board. This contract is available
only to employees or retired employees of The Joint Retirement Board of the
Rabbinical Assembly of America, The United Synagogue of America, and The Jewish
Theological Seminary of America (the "Joint Retirement Board"); (b) the level
deduction Contract; and (c) the graded deduction Contract. We currently offer
one type of Contract for HR-10 Plans. Each Contract may be modified or amended.

    If you surrender your Contract at the end of the applicable
    time period:
         You would pay the following expenses on a $1,000
         investment, assuming 5% annual return on assets:            $12       $39        $67        $147
    If you annuitize at the end of the applicable time period:
         You would pay the following expenses on a $1,000
         investment, assuming 5% annual return on assets:           $262      $289       $317        $397
    If you do not surrender your Contract:

</TABLE>
    
 
          We designed this table to help you understand the various costs and
     expenses that you will bear directly or indirectly. Contractholders
     currently pay an annual fee of .83% of average net assets. Under the
     administrative service agreement with the Joint Retirement Board, we deduct
     an additional fee of .35% from each Contractholder's net asset value as of
     August 1 of each year and pay this fee to the Joint Retirement Board. In
     addition to the expenses described above, premium taxes may be applicable.
     The information presented in the example listed above should not be
     considered a representation of past or future expenses. Actual expenses may
     be greater or lesser than those shown in the example. The participant has
     several different annuity options from which to choose. There is a $250
     annuity purchase fee only if the participant chooses a fixed rate annuity.

          We designed this table to help you understand the various costs and
     expenses that you will bear directly or indirectly. Contractholders
     currently pay an annual fee of .83% of average net assets. In addition to
     the expenses described above, premium taxes may be applicable. The
     information presented in the example listed above should not be considered
     a representation of past or future expenses. Actual expenses may be greater
     or lesser than those shown in the example. We deduct a sales load under
     these Contracts that vary from 0% to 7% depending on the Contract. The
     administrative expense under these Contracts varies from 0% to 1.5%
     depending on the contract. The participant has several different annuity
     options from which to choose. We charge a $250 annuity purchase fee only if
     the participant chooses a fixed rate annuity. CAC may deduct an additional
     charge for the maintenance of individual accounting records, not to exceed
     $20 for each new entrant and $10 per year per participant thereafter and
     $10 at each withdrawal. CAC did not deduct this charge in 1996, 1997 or
     1998. We deduct a $10 exchange fee for the second and succeeding transfer
     in most of the HR-10 Plan Contracts. We deduct a surrender fee (termination
     charge) of 2% of the Purchase Payments received prior to withdrawal when
     your Account is terminated and the entire interest in the Contract is
     withdrawn. We deduct a termination charge of 2% of the pro rata amount of
     Purchase Payments received when you withdraw part of your interest in the
     Contract.
    
 
   
          CAC believes the fees and charges deducted under the Contracts, in the
     aggregate, are reasonable in relation to the services rendered, the
     expenses expected to be incurred and the risks assumed by CAC.
    
 
THE INVESTMENT ADVISER AND
  INVESTMENT ADVISORY
  FEE......................  CAC acts as the investment adviser to Separate
                             Account (B). CAC is a stock life insurance company

403(B) PLAN SALES AND
  ADMINISTRATIVE CHARGES...  Joint Retirement Board Contract.  Under the current
                             403(b) Plan Contract with the Joint Retirement
                             Board, CAC does not deduct any charge for sales and
                             administrative expenses from Purchase Payments.
                             Under the administrative service agreement with the
                             Joint Retirement Board effective January 1, 1997,
                             each Participant under the Joint Retirement Board
                             Plan is charged a fee of .35% of the Participant's
                             net asset value as of each August 1. That fee is
                             remitted to the Joint Retirement Board for
                             administrative services performed by it on behalf
                             of Joint Retirement Board Plan Participants.
 
                             Level Deduction Contract.  Under the level
                             deduction Contract, we deduct 6% (6.38% of the net
                             amount invested) from each Purchase Payment for
                             sales and administrative expenses. Of such 6%
                             deduction, 5% is for sales expenses and 1% is for
                             administrative expenses. CAC reserves the right to
                             increase the rate of deductions for administrative
                             expenses in the future. Although CAC no longer
                             offers new level deduction Contracts to employers,
                             it continues to honor and to service existing level
                             deduction Contracts with current Contractholders
                             and to accept Purchase Payments under such
                             Contracts.
 
                             Graded Deduction Contract.  Under the graded
                             deduction Contract, we deduct up to 5% (5.26% of
                             the net amount invested) from each Purchase Payment
                             for sales expenses. We reduce the deduction on a
                             graduated scale based upon the aggregate Purchase
                             Payments made under both fixed and variable
                             annuities. The minimum deduction before allowance
                             for experience rating credits is 2.5% (2.57% of the
                             net amount invested). CAC also deducts an
                             administrative charge based upon the previous
                             year's cost of administration. There is no maximum
                             dollar limit on this charge. In 1999, CAC will
                             assess this charge at an annual rate of $30 per
                             participant.
 
HR-10 PLAN SALES AND
  ADMINISTRATIVE CHARGES...  We deduct a charge of 0 to 8.5% of Purchase
                             Payments (0 to 9.29% of the net amount invested)
                             from each Purchase Payment. This charge is the sum
                             of the following expenses:
 
                             -  sales expenses amounting to a deduction of 0 to
                                7.0% of Purchase Payments (0 to 7.65% of the net
                                amount invested); and
 
                             -  administrative expenses amounting to a deduction
                                of 0 to 1.5% of Purchase Payments (0 to 1.64% of
                                the net amount invested).
 
                             We credit the balance of the Purchase Payment,
                             after we deduct sales and administrative charges,
                             to the participant's account in the form of
                             Accumulation Units. The exact level of such charges
                             will vary from Contract to Contract, depending on
                             volume of Purchase Payments expected, services to
                             be performed by CAC and the applicable commission
                             expenses. Accordingly, we will not reduce sales
                             charges on
                                        9

                             individual Contracts upon attainment of any given
                             level of Purchase Payments. Certain Contracts may
                             also provide for additional annual fixed dollar
                             charges imposed on a per participant basis for the
                             maintenance of individual accounting records. CAC
                             reserves the right to increase the rate of
                             deductions for administrative expenses in the
                             future.
 
PURCHASE LIMITS............  The minimum Purchase Payment on Contracts for
                             403(b) Plans which can be made at any time on
                             behalf of any participant is $10. There is no
                             minimum Purchase Payment on Contracts for HR-10
                             Plans.

                             Separate Account (B) is the growth of capital in
                             relation to the growth of the economy and the
                             changing value of the dollar. Current investment
                             income is only a secondary objective. Separate
                             Account (B)'s investment policies require CAC, in
                             making investments for Separate Account (B), to
                             maintain Separate Account (B)'s status as a
                             diversified investment company. The dollar amount
                             of investment accumulation before retirement and
                             the dollar amount of subsequent retirement benefits
                             will vary to reflect the dividends, interest and
                             fluctuations in the market value of the securities
                             held in Separate Account (B) and will be subject to
                             the same risks to which any owner of common stocks
                             is subject.
 
TRANSFERS..................  Prior to beginning annuity payments, a participant
                             may transfer funds between fixed and variable
                             annuity contracts. Some of the 403(b) Plan
                             Contracts and HR-10 Plan Contracts that we offer
                             provide that any such transfer will be made without
                             charge. Others provide that CAC may charge a $10
                             exchange fee for the second and each succeeding
                             transfer in any calendar year. A participant may
                             change the percentage allocation of future Purchase
                             Payments between fixed and variable annuity
                             contracts at any time without charge.
 
ANNUITY SELECTION..........  The participant has several different annuity
                             options from which to choose. We charge a $250
                             annuity purchase fee if the participant chooses a
                             fixed rate annuity. For the other annuity options,
                             there is no fee. CAC reserves the right to change
                             these charges at any time.
 
WITHDRAWALS................  403(b) Plans.  A participant may withdraw, without
                             charge, all or a portion of his individual account
                             (except for certain amounts attributable to a
                             salary reduction agreement) before beginning
                             annuity payments by providing CAC with written
                             notice. However, effective January 1, 1997, under
                             the Joint Retirement Board Contract, a participant
                             must receive written consent from the Joint
                             Retirement Board prior to providing written notice
                             to CAC. A withdrawal may be subject to penalty
                             taxes, in addition to applicable federal income
                             taxes.

                             HR-10 Plans.  Subject to limitations, you may
                             withdraw part or all of your interest in the
                             Contract in one lump sum on any Valuation Date,
                             except for funds held for terminated or retired
                             participants. If you elect to make such a
                             withdrawal, CAC will deduct a termination charge of
                             2% of the pro rata amount of the Purchase Payments
                             received under the Contract relating to the
                             withdrawal.
 
PENALTY TAXES..............  Distributions made prior to age 59 1/2 generally
                             are subject to a penalty tax of 10%, in addition to
                             otherwise applicable federal income taxes. We will
                             not assess this penalty tax under the following
                             circumstances:
 
                             -  if the distribution is made in connection with
                                death or disability;
 
                             -  if the distribution is made after separation
                                from service where the separation occurred after
                                the participant attains age 55;
 
                             -  if the distribution is part of a series of
                                annual or more frequent annuity payments made
                                after separation from service and at least over
                                the life of the participant;
 
                             -  if the distribution is made for certain medical
                                expenses within the deductible limitation under
                                the Internal Revenue Code; or
 
                             -  if the distribution is made to an alternate
                                payee pursuant to a qualified domestic relations
                                order ("QDRO").

     (a) No declaration of dividends or distribution of gains is made, and such

     (b) Pursuant to the terms of the Investment Advisory Agreement, CAC makes
quarterly withdrawals for investment advisory services to Separate Account (B)
at an annual rate of .5% of the average net asset value and quarterly
withdrawals of a service fee at an annual rate of .33% of the average net asset
value.
 
     (c) Participants' equity appearing in the financial statements incorporated

     Separate Account (B) may from time to time measure performance in terms of
total return, which is calculated for any specified period of time by assuming
the purchase of units at Separate Account (B)'s unit value at the beginning of
the period. Such units are then valued at Separate Account (B)'s unit value at
the end of the period. The percentage increase is determined by subtracting the
initial value of the investment from its value at the end of the period and
dividing that amount by the initial value. The total return on this hypothetical
investment in Separate Account (B) shows its overall dollar or percentage change
in value, exclusive of fees based on the initial amount of the contribution and
recurring annual fees. If these fees were included, the amount or return that a
Participant would realize for an investment during the specified period would be
lower.

     A cumulative total return reflects Separate Account (B)'s performance over
a stated period of time. An average annual total return reflects the
hypothetical annually compounded return that would have produced the same
cumulative return if Separate Account (B)'s performance had been constant over
the entire period. Because average annual returns for more than one year tend to
smooth out variation's in Separate Account (B)'s annual returns, participants
should recognize that such figures are not the same as actual year-by-year
results. Separate Account (B) performance figures are based on historical
results and are not intended to indicate future performance. The investment
return and unit value of Separate Account (B) will vary and may be worth more or
less at redemption than their original cost.
 
     From time to time, Separate Account (B) may produce advertising or sales
materials which disclose its performance over various periods of time. Separate
Account (B) may also compare its performance to that of selected other funds,
fund averages or recognized stock market indices. Such performance ratings or
comparisons may be made with funds that may have different investment
restrictions, objectives, policies or techniques than Separate Account (B) and
the portfolios of such other funds or market indices may be comprised of
securities that differ significantly from Separate Account (B)'s investments.

                  DESCRIPTION OF CAC AND SEPARATE ACCOUNT (B)
 
GENERAL
 
     CAC is a stock life insurance company which was organized under the
Illinois Insurance Code in 1911, and has been an investment adviser registered
under the Investment Advisers Act of 1940 since 1966. Its life insurance
business involves the writing of group and individual life insurance, accident
and health insurance, and annuity policies. CAC's principal office is located at
CNA Plaza, Chicago, Illinois 60685.
 
     All of the voting securities of CAC are owned by Casualty, a stock casualty
insurance company organized under the Illinois Insurance Code, located at CNA
Plaza, Chicago, Illinois 60685. All of the voting securities of Casualty are
owned by CNA Financial, a Delaware corporation, located at CNA Plaza, Chicago,
Illinois 60685. Loews Corporation, a Delaware corporation, located at 667
Madison Avenue, New York, New York 10021-8087, with interests in insurance,
hotels, watches and other timing devices, drilling rigs and tobacco, owned
approximately 85% of the outstanding voting securities of CNA Financial as of
December 31, 1998. Laurence A. Tisch, the Chairman of the Board, Co-Chief
Executive Officer and a director of Loews Corporation and Chief Executive
Officer and a director of CNA Financial, and his brother, Preston R. Tisch,
President, Co-Chief Executive Officer and a director of CNA Financial and Loews
Corporation, owned, in the aggregate, approximately 31% of the outstanding
common stock of Loews Corporation as of December 31, 1998. Therefore, they may
be deemed to be parents of Loews Corporation, and thus of CNA Financial and CAC,
within the meaning of the federal securities laws.
 
     Separate Account (B) was established by CAC on June 1, 1966, under the
provisions of the Illinois Insurance Code, in order to fund variable annuity
contracts. In addition to serving as investment adviser to Separate Account (B),
CAC also serves as investment adviser to CNA Income Shares, Inc., a closed-end
diversified management investment company.
 
     Variable annuity contracts are securities within the meaning of the
Securities Act of 1933, and are not exempt from registration under the
provisions of that Act. The issuer of such contracts is subject to regulation
under the 1940 Act. Separate Account (B) has been registered as an open-end
diversified management investment company under the 1940 Act, but such
registration does not involve supervision of the management or the investment
practices or policies of Separate Account (B) or CAC by the SEC. Separate
Account (B) has no sub-accounts. Net Purchase Payments made in accordance with
the provisions of the Contracts described herein are added to Separate Account
(B) and invested as described herein. Net Purchase Payments made prior to April
29, 1977 under HR-10 Plan Contracts were added to Continental Assurance Company
Separate Account (A) and invested therein.
 
     CAC owns Separate Account (B)'s assets and, under existing law, is not
considered to be a Trustee with respect to those assets. Nevertheless, the
assets of Separate Account (B) are held for the benefit of the participants and
persons entitled to payments under the Contracts described in this prospectus.
Moreover, investment income and gains and losses from assets allocated to
Separate Account (B) (whether realized or not) are credited to or charged
against Separate Account (B) without regard to other income, gains or losses of
CAC (in accordance with the Contracts' provisions). Thus, the dollar amount of
payments or values which vary reflect the investment results of just Separate
Account (B). Additionally, the Illinois Insurance Code and the Contracts
themselves prohibit CAC from charging any liabilities arising out of other
business of CAC against Separate Account (B)'s assets (equal to the reserves and
other contract liabilities of Separate Account (B)).

INVESTMENT POLICIES AND RESTRICTIONS
 
     The objectives and policies in making investments for Separate Account (B)
are set forth below.
 
     1. The primary objective of CAC in making investments for Separate Account
        (B) will be the growth of capital in relation to the growth of the
        economy and the changing value of the dollar. Current investment income
        is only a secondary objective. Accordingly, the assets of Separate
        Account (B) will be invested primarily in common stocks and in other
        securities convertible into common stocks.
 
     2. When CAC believes that economic and market conditions indicate a
        likelihood that investing a majority of the assets of Separate Account
        (B) in common stocks or securities convertible into common stocks might
        result in a material decrease in the unit value of Separate Account (B),
        less than a majority of the assets of Separate Account (B) may be
        invested in common stocks or securities convertible into common stocks.
        In these situations, any assets not invested in common stocks or
        securities convertible into common stocks will be invested primarily in
        investment grade debt instruments with a maturity of one year or less,
        such as U.S. Treasury bills, bank certificates of deposit, bank
        repurchase agreements or commercial paper.
 
     3. When CAC deems that economic and market conditions so indicate, a
        portion of the assets of Separate Account (B) may be invested in
        preferred stocks and publicly distributed debt instruments such as
        corporate bonds, debentures, equipment trust certificates, U.S.
        Government securities or U.S. Government Agency securities.
 
     4. Temporary investments for Separate Account (B) may be made in short-term
        instruments such as U.S. Treasury Bills, bank certificates of deposit,
        bank repurchase agreements or commercial paper.
 
     5. To the extent of 75% of the assets of Separate Account (B), CAC may not
        purchase for Separate Account (B) the securities of any issuer if such
        purchase would cause more than 5% of the market value of Separate
        Account (B)'s assets to be invested in the securities of such issuer
        (other than obligations of the United States and its instrumentalities)
        or would cause more than 10% of any class of securities of such issuer
        to be held in Separate Account (B)'s portfolio. The balance of 25% of
        the assets of Separate Account (B) may be invested without regard to
        such 5% or 10% limitations.
 
     6. CAC, in acting for Separate Account (B), will not underwrite securities
        of others or invest in restricted securities.
 
     7. CAC, in acting for Separate Account (B), will not concentrate more than
        25% of Separate Account (B)'s investments in any one industry.
 
     8. The assets of Separate Account (B) will not be invested in commodity
        contracts.
 
     9. The assets of Separate Account (B) will not be invested in securities
        contracts of investment companies.
 
     10. CAC, in acting for Separate Account (B), will not make loans to other
         persons except through the acquisition of securities issued or
         guaranteed by banks, bonds, debentures, other debt securities which are
         publicly distributed and the lending of portfolio securities
         ("Portfolio Loans"). Portfolio Loans will be continually secured by
         cash, letters of credit, U.S. Government
 
                                       15
<PAGE>   18
 
       securities or U.S. Government Agency securities having a market value of
       not less than the market value of the portfolio securities loaned. The
       aggregate value of Portfolio Loans will not exceed 25% of Separate
       Account (B)'s net assets at any time.
 
     11. CAC, in acting for Separate Account (B), will not engage in the
         purchase and sale of interests in real estate, except that CAC may
         engage in the purchase and sale of marketable securities of real estate
         companies and real estate trusts which may represent indirect interests
         in real estate.
 
     12. CAC, in acting for Separate Account (B), will not purchase securities
         for the purpose of control or management of the issuer thereof.
 
     13. CAC will not make short sales for Separate Account (B).
 
     14. CAC will not borrow money for Separate Account (B).
 
     15. CAC will keep Separate Account (B)'s assets substantially fully
         invested in assets described in paragraphs 1, 2, 3 and 4 above, as
         described therein, and will limit Separate Account (B)'s cash position,
         to the extent feasible, to such amounts as may be required to permit
         CAC to make normal contract payments from Separate Account (B).
 
     16. CAC, in acting for Separate Account (B), will not issue any senior
         securities (as defined in the 1940 Act) except for the lending of
         portfolio securities permitted by paragraph 10 above.
 
     The investment policies enumerated above may not be changed without
approval of a majority (as defined in the 1940 Act) in interest of the
participants.
 
     There is no investment policy limitation as to the timing of sales and
purchase of securities. Although it will not be the general policy of CAC, in
acting for Separate Account (B), to engage in short term trading, securities may
be sold without regard to the length of time held whenever investment judgment
makes such action advisable. Since Separate Account (B) is not subject to
federal income taxes on capital gains, it is in a relatively advantageous
position in realizing capital gains even though an increased portfolio turnover
results in correspondingly greater brokerage expenses. The following table sets
forth Separate Account (B)'s rate of total portfolio turnover for the periods
indicated:
 
<TABLE>
<CAPTION>
RATE OF TOTAL PORTFOLIO TURNOVER                                PERCENT
- --------------------------------                                -------
<S>                                                             <C>
1998........................................................      41%
1997........................................................      45%
1996........................................................      53%
</TABLE>
 
     Changes in the rate of portfolio turnover from year to year are
attributable to changes in CAC's assessment of prevailing market conditions. All
investment income and realized capital gains will be reinvested. CAC, in acting
for Separate Account (B), will limit portfolio transactions to those which CAC,
in the exercise of prudent business judgment, deems advisable in order for
Separate Account (B) to carry out its investment policies and to make payments
to participants. The dollar amount of investment accumulation before retirement
and the dollar amount of subsequent retirement benefits will vary to reflect the
dividend, interest and fluctuations in the market value of the securities held
in Separate Account (B) and will be subject to the same risks as are inherent in
the ownership of common stocks.
 
     CAC, in acting for Separate Account (B), will not participate in any
trading account in securities on a joint or joint and several basis; provided,
however, that the bunching of orders for the sale or purchase of
                                       16
<PAGE>   19
 
marketable portfolio securities with those of other accounts under the
management of CAC or its affiliates and the averaging of prices among Separate
Account (B) and such other accounts will not be deemed to result in a trading
accounting securities. CAC, in acting for Separate Account (B), will not
mortgage or pledge the investments of Separate Account (B), purchase securities
on margin or, except as described below, invest in puts or calls. Unlike the
investment policies and restrictions stated in the preceding paragraphs, the
policies and restrictions described in this paragraph are subject to change
without vote of the participants.
 
     CAC, in acting for Separate Account (B), may write covered call options.
The "writing" of call options by Separate Account (B) means that Separate
Account (B) will be selling the right, but not the obligation, to acquire a
specified number of securities held in Separate Account (B)'s portfolio at a
price set in the option contract (the "exercise price"). The optionholder
generally may exercise this right to purchase the underlying securities at any
time prior to the expiration of the option by notifying Separate Account (B) of
its intention to exercise and delivering to Separate Account (B) funds equal to
the aggregate exercise price of the securities covered by the contract (the
"exercise payment"). Generally, a holder of a call option will exercise its
rights under the call option only if the market price of the underlying stock
exceeds the exercise price of the option. If the market price of the underlying
securities is greater than the option exercise price on the date of exercise,
the holder is, by virtue of the option contract, entitled to purchase the
underlying securities at the below-market exercise price. If the option is
exercised and the market value of the underlying securities exceeds the sum of
the exercise payment and the payment received by Separate Account (B) on the
sale of the option (the "premium"), Separate Account (B) would be left in a less
favorable position than if such call option had not been written (because of the
lost opportunity to realize the economic value represented by such excess).
 
     To close out a position when writing covered call options, Separate Account
(B) may make a "closing purchase transaction," which involves purchasing a call
option on the same security with the same or similar exercise price and
expiration date as the option which it has previously written. Separate Account
(B) will realize a profit or loss from a closing purchase transaction depending
upon the difference between the amount paid to purchase an option and the amount
received from the sale thereof.
 
     CAC, in acting for Separate Account (B), may also purchase covered put
options for hedging purposes. A put option gives the purchaser of the option the
right to sell, and obligates the writer to buy, the underlying securities at the
exercise price at any time during the term of the option. Generally, a holder of
a put option will exercise its rights under the put option, only if the market
price of the underlying securities is less than the exercise price of the
option. If the put option is not exercised or the amount by which the exercise
price exceeds the market price of the underlying securities is less than the
premium paid, Separate Account (B) would be left in a less favorable position
than if such put option had not been purchased. If market conditions are
appropriate for Separate Account (B) to exercise the purchased put option,
Separate Account (B) also may sell a put option to close out a purchased put
option rather than exercising the purchased put option.
 
     Separate Account (B) will write call options and purchase put options only
if the related stock is held in its portfolio. The put and call options
described above will generally have a contract term of nine months or less. The
market value of the securities subject to such option obligations at the time
such options are written or purchased will not, in the aggregate, exceed 20% of
Separate Account (B)'s total assets.
 
     The use of options exposes Separate Account (B) to certain additional
investment risks and transaction costs. The risks that may be associated with
the use of option contracts include, but are not
 
                                       17
<PAGE>   20
 
limited to, the risk that securities prices will not move in the direction
anticipated by Separate Account (B) and the risk that the skills needed to
successfully use option strategies may be different from those needed to select
portfolio securities. In addition, assets segregated or set aside to cover the
writing of a call option generally may not be disposed of during the term of
such option. Segregating assets could diminish Separate Account (B)'s return due
to the opportunity losses of foregoing other potential investments with the
segregated assets.
 
     CAC is permitted to enter into repurchase agreements and reverse repurchase
agreements on behalf of Separate Account (B). A repurchase agreement is an
instrument under which the purchaser (i.e., Separate Account (B)) acquires
ownership of the obligation (debt security) and the seller agrees, at the time
of the transfer, to repurchase the obligation at a mutually agreed upon time and
price, thereby determining the yield during the purchaser's holding period. This
results in a fixed rate of return insulated from market fluctuations during such
period. Repurchase agreements usually are for short periods, normally ranging
from one day to one month. Repurchase agreements will be entered into only with
respect to obligations in which Separate Account (B) may otherwise invest.
 
     A reverse repurchase agreement is an agreement under which the lender
(i.e., Separate Account (B)) loans a security, usually a U.S. Government
security, to a borrower, usually a bank or a stockbroker, against cash
collateral. The transaction is normally characterized as a loan by the lender of
the security and a simultaneous agreement by the lender to repurchase such
security at an agreed price at a specified later date. The transaction is
normally structured to permit the lender to receive a yield in excess of the
yield of the underlying security. Reverse repurchase agreements are usually made
for short periods, normally ranging from one week to one month. A reverse
repurchase agreement will be a Portfolio Loan permitted by paragraph 10 above.
Sufficient funds will be maintained in the form of cash and short-term
investments, and segregated on an accounting basis, to satisfy such repurchase
commitments.
 
     The Federal Bankruptcy Code provides that a repurchase participant may
enforce a clause requiring the liquidation of a repurchase agreement because of
the insolvency or financial condition of the other party to the repurchase
agreement or because of the commencement of the bankruptcy case by the other
party to the repurchase agreement. The Federal Bankruptcy Code also provides
that the automatic stay does not apply to the set-off by a repurchase
participant of a mutual debt or claim in connection with repurchase agreements
where the set-off is for a margin payment or a settlement payment. Repurchase
agreements are narrowly defined by Section 101(47) of the Bankruptcy Code to
mean only agreements involving the transfer of certificates of deposit, eligible
banker's agreements or securities that are direct obligations of or fully
guaranteed by the United States government. Repurchase agreements not falling
within this definition may not be covered by the protection of Sections 559 and
362(b)(7) of the Bankruptcy Code. It is possible that repurchase agreements not
covered by those sections may be considered by a bankruptcy court to be loans by
the purchaser to the seller. In such event, the purchaser might not be able to
sell the obligation in the event of bankruptcy of seller without leave of the
appropriate court. The purchaser would then be at risk due to a decline of the
value of the obligation, and in the event of bankruptcy would face delays in the
sale of the obligation and would incur legal, disposition and other expenses.
 
     CAC will limit investments by Separate Account (B) which may not be sold
and settlement received therefor within three business days (or such shorter
settlement period as the Commission designates for investment companies as
defined under the 1940 Act) to 10 percent of the net assets of Separate Account
(B).

                                   MANAGEMENT
 
THE COMMITTEE
 
     The supervision of Separate Account (B) is vested by CAC in a Committee.
The Committee has the following specific duties:
 
     1. To review periodically the portfolio of Separate Account (B) to
        ascertain that such portfolio is managed in the long-term interest
        of the participants and to take such corrective action as may be
        necessary.
 
     2. To approve, annually, agreements providing for sales, investment
        and administrative services.
 
     3. To recommend from time to time any changes deemed appropriate in
        the fundamental investment policies of Separate Account (B), to be
        submitted to the participants at their next meeting.
 
     4. To select independent auditors, whose engagement shall be approved
        annually by the participants.
 
     The Committee is also authorized to amend the Regulations for Government of
Separate Account (B), except as otherwise provided by law.
 
INVESTMENT ADVISORY AGREEMENT
 
     Under the Investment Advisory Agreement, CAC acts as the investment adviser
to Separate Account (B). In rendering its services as investment adviser, CAC is
responsible to the Committee. CAC, as Separate Account (B)'s investment adviser,
provides Separate Account (B) with an investment program complying with the
investment objectives, policies and restrictions of Separate Account (B) (see
"Description of CAC and Separate Account (B)--Investment Policies and
Restrictions"). In carrying out Separate Account (B)'s investment program, CAC
makes the investment decisions and is responsible for the investment and
reinvestment of the Separate Account's assets by the purchase and sale of
securities on behalf of the Separate Account. CAC performs research, statistical
analysis, and continuous supervision of Separate Account (B)'s investment
portfolio, and also furnishes office space for Separate Account (B) and pays the
salaries and fees of Separate Account (B)'s officers and Committee Members. The
Investment Advisory Agreement does not require employees of CAC to devote their
exclusive efforts to Separate Account (B)'s business, and it is expected that
they will provide investment advisory services for CAC's other customers and for
CNA Financial and its affiliates.

SALES AND ADMINISTRATIVE CHARGES--GENERAL
 
     CAC may be deemed to be the principal underwriter for Separate Account (B)
and performs all sales and administrative functions relative to the Contracts
and Separate Account (B). CAC does not act as principal underwriter for any
other investment company.

     CAC, in its sole discretion, may grant an experience rating credit to
participants covered by a 403(b) Plan Contract based upon its profitability.
Experience rating credits of 1% to 5% of Purchase Payments have been granted in
certain cases where substantial individual solicitation has not been necessary.
 
SALES AND ADMINISTRATIVE CHARGES--403(B) PLANS
 
     The following is an overview of the sales and administrative charges
applicable to the different types of 403(b) Plans offered by Separate Account
(B):
 
     JOINT RETIREMENT BOARD CONTRACT.  Under the administrative service
agreement with the Joint Retirement Board, effective January 1, 1997, each
Participant under the Joint Retirement Board Plan is charged a fee of .35% of
the Participant's net asset value as of each August 1. That fee is remitted to
the Joint Retirement Board for administrative services performed by it on behalf
of its 403(b) Plan Participants.
 
     LEVEL DEDUCTION CONTRACTS.  Pursuant to the Administrative Service
Agreement, and as provided in the Contracts, CAC currently deducts 6% (6.38% of
the net amount invested) from each Purchase Payment as received for sales
expenses and administrative expenses. Of such 6% deduction, 5% is for sales
expenses and 1% is for administrative expenses. These charges do not cover the
expenses covered by the service fee charged under the Investment Advisory
Agreement. CAC guarantees that during the first five years of a participant's
participation under the Contract no further deductions will be made to cover
such expenses, but any part of the 6% aggregate charge not needed to cover such
expenses accrues as a profit to CAC. Following the end of the fifth year of
participation under the Contract, the 1% deduction by CAC from Purchase Payments
to cover administrative expenses may be increased by CAC upon prior written
notice to the participant.
 
     GRADED DEDUCTION CONTRACTS.  Pursuant to the Administrative Service
Agreement, and as provided in the Contracts, to cover sales expenses CAC makes
deductions from Purchase Payments as follows:
 
     -  5% (5.26% of the net amount invested) on the first $10,000 of
        Purchase Payments for each participant;
 
     -  4% (4.17% of the net amount invested) on the next $10,000 of
        Purchase Payments for each participant; and
 
     -  2.5% (2.57% of the net amount invested) on all Purchase Payments
        for each participant in excess of $20,000.
 
     Total Purchase Payments for each participant under both fixed and variable
annuity contracts are included in determining the charge. Any part of such
charge which is not needed to cover such expenses accrues as a profit to CAC.
 
                                       20
<PAGE>   23
 
     Pursuant to the Administrative Service Agreement, and as provided in the
Contracts, CAC makes an administrative charge based upon its cost of
administration. There is no maximum dollar limit on this charge, except that
this charge (for any given year) will not exceed the previous year's cost of
administration. This charge is made on December 31st of each year against the
account of each participant who is not receiving an annuity. In 1999, CAC will
assess this charge at an annual rate of $30 per participant.
 
     Neither the sales charge nor the administrative charge covers the expenses
covered by the service fee charged under the Investment Advisory Agreement.
 
     In the event Purchase Payments are made on behalf of a participant who is
in the accumulation period for a partial year, the administrative charge is
prorated on a monthly basis. For example, if the annual charge for a calendar
year is $30 and the participant is covered under the Contract prior to the
beginning of annuity payments for only eight months of that year, his
administrative charge would be $20.
 
     If no Purchase Payments are received on behalf of a participant during a
calendar year, the deduction from the participant's account for that year will
be 50% of the administrative charge which would otherwise be made. For example,
if the annual charge for a calendar year is $30 and the participant is in the
accumulation period during the entire calendar year but no Purchase Payments are
received on behalf of the participant during the year, his administrative charge
would be 50% of $30 or $15.
 
SALES AND ADMINISTRATIVE CHARGES--HR-10 PLANS
 
     Pursuant to the Administrative Service Agreement, and as provided in the
Contracts, each Purchase Payment received by CAC under an HR-10 Plan Contract
is, after deduction of a percentage charge, credited to Separate Account (B).
The charge ranges from 0 to 8.5% of Purchase Payments (0 to 9.29% of the net
amount invested) comprised of 0 to 7% of Purchase Payments (0 to 7.65% of the
net amount invested) to cover sales expenses and 0 to 1.5% of Purchase Payments
(0 to 1.64% of the net amount invested) to cover certain administrative
expenses. This charge does not cover the expenses covered by the service fee
charged under the Investment Advisory Agreement. CAC guarantees that, except for
this charge and the charges described below, no further deductions will be made
for sales and administrative expenses. While CAC intends that this charge merely
cover such expenses, if any part of this charge is not needed to cover such
expenses, such part accrues as a profit to CAC. Conversely, if such expenses
exceed this charge, a loss to CAC results. The exact level of this charge will
vary from Contract to Contract, depending on the volume of Purchase Payments
expected, the extent of administrative services to be performed by CAC and the
applicable commission expenses. The Contractholder, before entering into a
Contract, and each self-employed or other person subject to the Contract, before
agreeing to make Purchase Payments thereunder, will be given a separate written
statement showing the percentage amount of such charge.
 
     If the Contract so provides, CAC may make additional fixed dollar charges
per participant for the maintenance of individual accounting records. These
charges will not exceed $20 for each entry into the plan relating to such
Contract, $10 per year per participant thereafter, and $10 at each withdrawal.
The initial charge levels anticipated by CAC will be furnished at the time that
application for the Contract is under consideration, and the charges provided
for will be based upon CAC's good faith estimate of the cost to it for the
maintenance of individual accounting records. At the present time, there are no
Contracts in force under which fixed dollar charges per participant are made.
 
                                       21
<PAGE>   24
 
     No increase in the percentage charge for sales and administrative expense,
or in any charge per participant, may be made during the first five Contract
years. After the first five Contract years, the portion of such charges intended
to cover administrative expenses may be changed on the basis of CAC's expenses.
 
INVESTMENT ADVISORY CHARGES
 
     CAC makes quarterly withdrawals from Separate Account (B) as follows:
 
     -  at an annual rate of 0.5% of the average daily net asset value of
       Separate Account (B) for providing investment advisory services, and
 
     -  at an additional annual rate of 0.33% of the average daily net
       asset value of Separate Account (B) as a service fee for bearing
       certain expenses of Separate Account (B). Such expenses are
       different from those covered by the Administrative Service
       Agreement.
 
                DESCRIPTION OF GROUP VARIABLE ANNUITY CONTRACTS
 
GENERAL
 
     The Contracts provide one method of investing retirement funds in equity
and other securities. The primary purpose of the Contracts is to provide
lifetime payments which will tend to reflect changes in the cost of living
during both the years prior to retirement and the years following retirement.
CAC seeks to accomplish this objective by providing a medium for investment,
generally in equity securities, accompanied by an assumption of the mortality
risk. However, there can be no assurance that this objective will be attained.
 
     The Contracts involve investment risk, including possible loss of
principal. The value of the investments fluctuates continuously and is subject
to the risks of changing economic conditions as well as the risks inherent in
the ability of CAC to anticipate changes in such investments necessary to meet
changes in economic conditions. There can be no assurance that the value of a
participant's individual account during the years prior to retirement, or the
aggregate amount of the variable annuity payments received during the years
following retirement, will equal or exceed the Purchase Payments made on his
behalf. The Contracts are not a deposit or obligation of, or guaranteed or
endorsed by, any bank or depository institution, and the Contracts are not
federally insured by the Federal Deposit Insurance Corporation, The Federal
Reserve Board, or any other governmental agency.
 
     The variable annuity payments are determined on the basis of (1) the
mortality table specified in the Contract, and (2) the investment performance of
Separate Account (B). The dollar amount of the variable annuity payments will
not be affected by adverse mortality experience or by an increase in CAC's
expenses in excess of the expense deductions provided for in the Contract. The
dollar amounts of the payments will, however, reflect the investment losses or
gains and investment income, and thus will vary.
 
     The significant difference between a regular or fixed annuity and a
variable annuity is that under a fixed annuity, the insurance company assumes
the risk of investment gain or loss and guarantees a specified interest rate and
a specified monthly annuity payment. Under a variable annuity, the participant
assumes the risk of investment gain or loss in that the value of his individual
account varies with the investment income and gains or losses of a specified
portfolio of securities. In both cases, the insurance company assumes the
mortality and expense risk under the Contract.
 
                                       22
<PAGE>   25
 
     In assuming the mortality risk, CAC is taking the chance that the actuarial
estimate of mortality rates among annuitants may prove erroneous; in assuming
the expense risk, CAC is taking the chance that the expense margins deducted by
CAC may not prove sufficient to cover the actual sales and administrative costs
and contingency requirements. In either case, if an error in estimation is
against CAC, CAC's earnings will be reduced; if an error in estimation favors
CAC, CAC's earnings will be increased.
 
SALES OF CONTRACTS
 
     The Contracts are offered by employees and licensed agents and brokers of
CAC.
 
VOTING RIGHTS
 
     Participants have the right to vote at any annual meeting of participants
upon the following matters:
 
          1. To elect Members of the Committee for Separate Account (B)
     (see "Management--The Committee").
 
          2. To approve or disapprove any new or amended agreement providing for
     investment services.
 
          3. To approve or disapprove any changes in the fundamental
     investment policies of Separate Account (B).
 
          4. To ratify or reject the Committee's selection of independent
     auditors for Separate Account (B).
 
     The Committee currently intends to hold annual meetings of participants for
these purposes. However, there is no requirement under applicable law that
Separate Account (B) hold regular annual meetings of participants and the
Committee, in its discretion, may continue holding regular annual meetings of
participants in the future. Meetings of participants are required by the 1940
Act in certain circumstances, including to approve any change in fundamental
investment policies.
 
     The number of votes which a participant who is not retired may cast is
equal to the number of Accumulation Units held by such participant under the
particular Contract concerned, which represent interests in Separate Account
(B). The number of votes which a retired participant may cast is equal to the
monetary value of the actuarial reserve maintained by CAC in Separate Account
(B) for the annuity of that participant divided by the monetary value of an
Accumulation Unit. As payments are made to a retired participant, the monetary
value of that actuarial reserve is reduced; accordingly, the number of votes
which that retired participant may cast will decrease.
 
     The determination of the number of votes to be cast will be made as of a
date within 60 days prior to the annual meeting of the participants. The
participants will receive at least 20 days' prior written notice of such meeting
and of the number of votes to which they are entitled. A participant will be
entitled to vote only if he is a participant on the foregoing record date and on
the date of the meeting.
 
ASSIGNMENT
 
     The interest of any participant or beneficiary in or under a Contract is
not subject to assignment or transfer. Transfer or surrender of such interest
may be made only to CAC.
 
                                       23
<PAGE>   26
 
MODIFICATION OR TERMINATION OF THE CONTRACT
 
     Each Contract provides that it may be modified or amended in any respect by
agreement between CAC and the Contractholder, without the consent of any
participant. However, no such modification or amendment may affect retired
participants in any manner, nor may any guarantees previously extended to active
participants be impaired. CAC may also modify or amend any Contract, without
your consent or the consent of any participant, in order to conform to
applicable law or to changes in the operation of Separate Account (B) which have
been approved by vote of the participants or by the Committee.
 
     A Contractholder may elect to terminate a Contract at any time by due
notice to CAC. An HR-10 Plan Contractholder has an option to transfer funds to a
new funding medium (for example to a fixed annuity contract). If an HR-10 Plan
Contract is terminated without transfer of funds to a new funding medium or if a
403(b) Plan Contract is terminated, the rights of the participants are the same
as on termination of employment or other withdrawal. When a participant begins
to receive annuity payments, his rights are fixed and are not affected by any
Contract termination.
 
CONTRACTHOLDER INQUIRIES
 
     All inquiries by Contractholders, Employers or participants should be made
in writing or by telephone to:
 
                                Continental Assurance Company
                                Attn: Individual Pension Accounts-35S

PURCHASE PAYMENTS AND ACCUMULATIONS
 
     The minimum Purchase Payment on Contracts for 403(b) Plans is $10, which
may be made at any time on behalf of any participant.
 
     There is no minimum Purchase Payment on Contracts for HR-10 Plans. The
HR-10 Plan Contracts permit a variety of payment schedules. A retirement plan
for the self-employed may provide for a fixed percentage of compensation to be
paid by all Employers who are participating, and additional payments to be made
by them on behalf of any of their employees who may also be eligible. If the
plan incorporates a provision for employee payments, these would normally be
deducted regularly from their compensation during the year, and remitted
directly to CAC as collected.
 
ALLOCATION OF PURCHASE PAYMENTS--HR-10 PLANS
 
     HR-10 Plans adopted by an Employer may provide for other investments in
addition to the Contracts. For example, these plans may also provide for
purchase of life insurance or fixed annuities. The terms of the plan adopted
will set forth the method of allocation of Purchase Payments between the
Contracts and other applications. There may be different allocations among the
participants under a plan. Reallocation of prior Purchase Payments between the
Contracts and insurance or fixed annuity contracts will be permitted prior to
retirement only with the consent of CAC. If the plan so provides, a participant
may upon retirement change the proportion of annuity to be paid on a fixed or
variable basis.

ACCUMULATION PERIOD
 
     During the period before of annuity payments begin, when a Purchase Payment
is received on behalf of a participant, a sales and administrative charge is
deducted. The balance of the Purchase Payment is credited to the participant's
account in the form of Accumulation Units. The number of Accumulation Units
credited for a participant is determined by dividing the amount credited to his
account by the value of an Accumulation Unit next computed after receipt of the
Purchase Payment at the principal office of CAC, CNA Plaza, Chicago, Illinois
60685. The credit to the participant's account occurs concurrently with such
determination.
 
VALUE OF AN ACCUMULATION UNIT
 
     During the accumulation period, the value of a participant's account varies
with the performance of the investments of Separate Account (B), and there is no
assurance that such value will equal or exceed Purchase Payments made on behalf
of the participant.
 
     Accumulation Units are valued as of 3:00 P.M., Central Time, on each day on
which the New York Stock Exchange is open and on each other day in which there
is a sufficient degree of trading in the portfolio securities of Separate
Account (B) that the current net asset value of Accumulation Units might be
materially affected by changes in the value of such portfolio securities, with
each day of valuation being referred to as a Valuation Date.
 
     The value of an Accumulation Unit on a Valuation Date is determined by
dividing the net asset value of Separate Account (B) at the close of business on
that day by the number of Accumulation Units outstanding. Receipt of investment
income or realization of capital gains by Separate Account (B) will not change
the number of Accumulation Units outstanding. This number ordinarily may be
increased only through receipt of additional Purchase Payments, and decreased
only through withdrawals. The value of an Accumulation Unit on any day not a
Valuation Date will be the same as the value on the next Valuation Date.
 
     The net asset value of Separate Account (B) is the market value of all
securities and other assets, less liabilities of Separate Account (B), including
accrued investment advisory fees and other service fees. We determine the net
asset value of Separate Account (B) by valuing:
 
     -  portfolio securities which are traded on a national securities
        exchange at the last sale price, or, in the absence of a sale, at
        the closing bid price on the exchange where the security is
        primarily traded;
 
     -  other securities the prices of which are quoted in the Nasdaq
        National Market at the last sale price or, in the absence of a
        sale, at the closing bid price;
 
     -  other over-the-counter market securities not quoted in the Nasdaq
        National Market on the basis of the bid price of over-the-counter
        market quotations, if available; and
 
     -  all other securities and other assets at a fair value determined in
        good faith by the Committee.
 
     Under current federal laws, no federal income tax is payable on income or
capital gains of Separate Account (B). In the event any income taxes are
imposed, they will be deducted in determining the net asset value of Separate
Account (B). Deductions are also made by CAC for investment advisory services
and other services at such prorated percentages as are equivalent to an
aggregate of 0.83% per annum of
 
                                       25
<PAGE>   28
 
the average daily net asset value of Separate Account (B), under CAC's
Investment Advisory Agreement with Separate Account (B).
 
     The value of an Accumulation Unit was established as $1.00000 ($1) on June
30, 1966, and the initial deposits were applied at that initial unit value on
February 28, 1967. The value as of any later date is found as described above.
The value of a participant's account at any date can be determined by
multiplying the total number of Accumulation Units credited to his account by
the value of an Accumulation Unit on that date.
 
WITHDRAWALS
 
     Subject to the limitations described in "Benefits on Death or
Withdrawal--HR-10 Plans", an HR-10 Plan Contractholder may withdraw from CAC, in
one lump sum on any Valuation Date, part or all of his or her interest in the
Contract, except for funds held for terminated or retired participants. If you
elect to make such a withdrawal, CAC will deduct a termination charge of 2% of
the pro rata amount of the Purchase Payments received under the Contract before
your withdrawal. In general, any withdrawal made prior to age 59 1/2 (other than
on account of death, disability, separation from service during or after the
employee attains age 55, or a withdrawal which is part of a series of annual or
more frequent annuity payments made after separation from service and at least
over the participant's life, or if the withdrawal is made for certain medical
expenses within the deductible limits under the Internal Revenue Code or if it
is made to an alternate payee pursuant to a QDRO) is subject to an additional
10% tax, under the Internal Revenue Code.
 
     A participant may elect, by written notice to CAC, to withdraw all or a
portion of his individual account other than certain amounts attributable to a
salary reduction agreement prior to beginning annuity payments. However,
effective January 1, 1997, under the Joint Retirement Board Contract, a
participant must receive written consent from the Joint Retirement Board prior
to providing written direction to CAC. CAC will redeem Accumulation Units from
participants, without any charge, at the net asset value per Accumulation Unit
next to be determined after receipt of a signed written request to the office of
CAC. However, withdrawals prior to age 59 1/2 (except for the exceptions stated
in the above paragraph) are generally subject to an additional 10% tax.
Distributions from a 403(b) Plan of amounts contributed on or after January 1,
1989 pursuant to a salary reduction agreement and of earnings on those
contributions (and amounts earned on or after January 1, 1989 on contributions
made before January 1, 1989) may be made only upon the attainment of age 59 1/2,
separation from service, death, disability or hardship. Hardship distributions
are limited to amounts contributed pursuant to a salary reduction agreement,
excluding earnings on those amounts. Payment for Accumulation Units redeemed
will be made by CAC within seven days after receipt of a written redemption
request by CAC at the address set forth above under "Description of Group
Variable Annuity Contracts--Contractholder Inquiries". Payments upon redemption
may be more or less than the original costs of the Accumulation Units. For a
discussion of federal income tax consequences of the receipt of such lump sum
payments, see "Federal Taxes--Federal Tax Treatment of Participants".

                                   ANNUITIES
 
ELECTING THE RETIREMENT DATE AND FORM OF ANNUITY--403(B) PLANS
 
     A participant selects, in accordance with the Contract, a retirement date
and annuity option. CAC currently charges a $250 fee for the purchase of a fixed
rate annuity. CAC reserves the right to change this charge at any time. Prior to
beginning annuity payments, a participant may transfer funds between fixed and
variable annuity contracts. Some of the 403(b) Plan Contracts offered hereby
provide that any such transfer will be made without charge. Others provide that
CAC may make a charge of $10 for the second and each succeeding transfer in any
calendar year. A participant may change the percentage allocation of future
Purchase Payments between fixed and variable annuity contracts at anytime
without charge. Subsequent changes in either the retirement date or annuity
option can be made up to 30 days prior to the date annuity payments are to
begin. Distributions must generally begin by April 1 of the year following the
year of attainment of age 70 1/2 or, if later and the participant was not a sole
proprietor or Five Percent Owner with respect to the year in which he or she
reached age 70 1/2 and such participant so elects, by April 1 of the year
following the year in which the participant retires (a different rule may apply
with respect to distributions made in plan years beginning before January 1,
1997--consult your tax advisor). The 403(b) Plan Contracts provide for the
various annuity forms described below. Level deduction Contract participants
have three annuity forms; graded deduction Contract participants have four.
There is an additional annuity form, which is not one of the four options
described below, which is applicable only to plans providing for a qualified
joint and survivor annuity as defined in ERISA. That annuity form is described
following the descriptions of the four options. The annuity payments may be
either fixed or variable at the option of the participant.
 
ANNUITY OPTIONS--403(B) PLANS
 
     The following annuity options are available under 403(b) Plans offered by
Separate Account (B):
 
     -  OPTION 1--LIFE WITHOUT REFUND. Monthly payments for the life of the
        participant only.
 
     -  OPTION 2--LIFE TEN YEARS CERTAIN. Monthly payments for life, with the
        provision that if, at the death of the annuitant, payments have been
        made for less than 120 months, annuity payments may, at the option of
        the beneficiary designated by the participant, be discounted and paid in
        a single sum, or be continued during the remainder of said period to the
        beneficiary. If the beneficiary dies while receiving annuity payments,
        the value on the date of death of the remaining number of annuity
        payments will be paid in a lump sum to the estate of the beneficiary.
        This option is considered by CAC to be the "normal form". Unless the
        Plan adopted by the Contractholder and communicated to CAC provides for
        a qualified joint and survivor annuity as defined in ERISA, this option
        will be applied automatically if no other option is elected.
 
     -  OPTION 3--JOINT AND SURVIVOR. Monthly payments to the participant for
        his life, continuing on the basis of the same number of Annuity Units
        after the participant's death to his spouse, for the balance of his
        spouse's life.
 
     -  OPTION 4--LIFE FIVE YEARS CERTAIN. Monthly payments for life, with a
        provision similar to that under the Life Ten Years Certain form, but
        extending only five years from retirement. This option may only be
        selected by participants under the graded deduction Contract.
 
                                       27
<PAGE>   30
 
     Ordinarily, no option may be elected if the first payment under such option
would be less than $25. If the amount of such first payment would be less than
$25, it will be paid in a lump sum.
 
     No option may be elected which has a period certain longer than the life
expectancy of the participant or the joint and last survivor life expectancies
of the participant and the participant's contingent annuitant, calculated, based
on such persons' attained ages in the year in which payments are required to
begin, using the mortality table provided for such purpose by the Secretary of
the Treasury. Further, with respect to benefits accrued after December 31, 1986,
the distribution cannot exceed a maximum period of years determined under tables
provided by the Secretary of the Treasury, and additional rules apply in
determining the minimum amount which must be distributed each year.
 
     If a plan adopted by the Contractholder and communicated to CAC provides
for a qualified joint and survivor annuity as defined in ERISA as the automatic
form of payment, then unless the participant waives such form and his spouse
consents, the automatic annuity form under the Contract for each participant to
whom such provision is applicable will be an annuity for the life of the
participant which provides a survivor annuity for the life of the participant's
surviving spouse which is not less than one-half, nor greater than the full
amount, of the annuity payable during the life of the participant, and which is
the actuarial equivalent of a single life annuity with ten years certain for the
life of the participant. Any participant who affirmatively waives the automatic
annuity form with the consent of his spouse may select any of the options
described above if he is covered by a graded deduction Contract or any of
Options 1, 2 or 3 if he is covered by a level deduction Contract.
 
     If Option 1 is elected, subsequent to the death of the participant no
payments are made to any person, and if Option 3 is elected, subsequent to the
death of the last to die of the participant and the participant's spouse no
payments are made to any person.
 
     Other options are available with the consent of CAC. Information on such
options will be furnished upon written request to CAC.
 
RETIREMENT OF PARTICIPANT--HR-10 PLANS
 
     Distributions must generally begin by April 1 of the year following the
year of attainment of age 70 1/2, or, if later and the participant so elects, by
April 1 of the year following the year in which the participant retires (a
different rule may apply with respect to 5% Owners and distributions made in
plan years beginning before January 1, 1997. Consult your tax advisor).
 
     The HR-10 Plan Contract is flexible in allowing retirement on the first day
of any month as elected by the participant and specified in the plan. The only
requirements are that the initial monthly annuity payment must be at least equal
to a minimum amount established by CAC from time to time, and that the
participant must submit certain information to establish proof of his date of
birth. If the annuity would be less than the minimum, it may be paid as a
fixed-value income, or in a lump sum.
 
ANNUITY OPTIONS--HR-10 PLANS
 
     The form of annuity payable to retired participants of a particular
organization depends on the terms and provisions of the plan adopted by that
organization. Annuity options normally available under the Contract, if the plan
so provides, will include the following listed below, provided that the option
selected must produce an initial monthly annuity payment in the amount of at
least $25. CAC currently charges $250 for the purchase of a fixed rate annuity.
CAC reserves the right to change this charge. Prior to
 
                                       28
<PAGE>   31
 
beginning annuity payments, a participant may transfer funds between fixed and
variable annuity contracts. Some of the HR-10 Plan Contracts offered hereby
provide that any such transfer will be made without charge. Others provide that
CAC may make a charge of $10 for the second and each succeeding transfer in any
calendar year. A participant may change the percentage allocation of future
Purchase Payments between fixed and variable annuity contracts at any time
without charge.
 
     The following annuity options are available under HR-10 Plans offered by
Separate Account (B):
 
     -  OPTION 1--LIFE TEN YEARS CERTAIN.  Monthly payments for life, with
        the provision that if, at the death of the annuitant, payments have
        been made for less than 120 months, annuity payments will be
        discounted at the reserve interest rate, and paid to the
        beneficiary in a single sum. This option is considered by CAC to be
        the "normal form." Unless the plan adopted by the Contractholder
        and communicated to CAC provides for a qualified joint and survivor
        annuity as defined in ERISA, this option will be applied
        automatically if no other option is elected.
 
     -  OPTION 2--LIFE FIVE YEARS CERTAIN.  Monthly payments for life, with
        a provision similar to that under the Life Ten Years Certain form,
        but only extending for five years from retirement.
 
     -  OPTION 3--LIFE WITHOUT REFUND.  Monthly payments for the life of
        the participant only.
 
     -  OPTION 4--JOINT AND SURVIVOR.  Monthly payments to the participant
        for his life, continuing on the basis of the same number of Annuity
        Units after the participant's death to his spouse, for the balance
        of his spouse's life.
 
     -  OPTION 5--FIXED INSTALLMENTS.  Level monthly payments of a
        stipulated dollar amount, payable until the sum applied is
        exhausted. The period for which payments are made will vary
        depending upon the investment results of the Account.
 
     -  OPTION 6--FIXED PERIOD.  Variable monthly payments payable over a
        predesignated period of years, from one to twenty.
 
     In the case of options with a fixed period, the beneficiary may, in lieu of
a lump sum settlement, elect to have the remaining installments continued on a
monthly basis. This election is available only if the beneficiary is a natural
person.
 
     No option may be elected which has a certain period longer than the life
expectancy of the participant or the joint and last survivor life expectancies
of the participant and the participant's beneficiary calculated based on such
persons' attained ages in the years in which payments are required to begin,
using the mortality table prescribed for such purpose by the Secretary of the
Treasury. Additional special rules apply in determining the minimum amount which
is required to be distributed each year. Life expectancies of the participant
and the participant's spouse will be redetermined annually unless the plan
provides otherwise.
 
     If a plan adopted by the Contractholder and communicated to CAC provides
for a qualified joint and survivor annuity as defined in ERISA then, unless the
participant waives such automatic form of payment with the consent of the
participant's spouse, the automatic annuity form under the Contract for each
participant to whom such provision is applicable will be an annuity for the life
of the participant which provides a survivor annuity for the life of the
participant's spouse which is not less than one-half, nor greater than the full
amount, of the annuity payable during the life of the participant, with respect
to a
                                       29
<PAGE>   32
 
defined benefit plan, which is the actuarial equivalent of a single life annuity
with ten years certain for the life of the participant and, with respect to a
defined contribution plan, is the annuity which can be purchased with the
participant's individual account balance. Any participant who affirmatively
waives the automatic annuity form with the consent of his spouse may select any
of the options described above.
 
     If Option 3 is elected, subsequent to the death of the participant no
payments are made to any person, and if Option 4 is elected, subsequent to the
death of the last to die of the participant and the participant's spouse no
payments are made to any person.
 
                                ANNUITY PAYMENTS
 
DETERMINATION OF AMOUNT OF THE FIRST MONTHLY VARIABLE ANNUITY PAYMENT
 
     As of the date annuity payments are to begin, the value of a participant's
account is computed by multiplying the value of an Accumulation Unit on the
fifteenth day of the preceding calendar month (or the next working day if the
15th falls on a Saturday, Sunday or holiday) by the number of Accumulation Units
credited to the participant's account, and subtracting from the resulting figure
any premium tax that is applicable under state law to the purchase of the
participant's annuity. Such premium taxes range from 0 to 3%. Regardless of the
date on which premium taxes are deducted from the accounts of participants, such
taxes are remitted by CAC to applicable state taxing authorities once per
calendar year. Certain states provide for credits against premium tax
liabilities based upon CAC's ownership of properties or investments located
therein (none of which are assets of Separate Account (B)). In the event that
CAC is able to avail itself of such credits, the resulting saving is not passed
on to participants from whose accounts premium taxes have been deducted.
 
     Each Contract contains tables setting forth the dollar amount of the first
monthly annuity payment which can be purchased by each $1,000. These tables vary
according to the type of Contract, the form of annuity selected by the
participant and the sex and age on the nearest birthday of the participant. The
tables are based on the 1951 Group Annuity Table projected 14 years with
projection scale C and with interest at the assumed investment rate of 3 1/2%.
Participants under the graded deduction Contract--403(b) Plan may also elect an
optional rate of 3%, 4%, 4 1/2% or 5%. The first monthly annuity payment for a
particular annuity form may be found by dividing the value of the participant's
individual account by $1,000 and multiplying this number by the annuity rate
from the applicable table.
 
DETERMINATION OF THE VALUE OF AN ANNUITY UNIT AND AMOUNT OF SECOND AND
SUBSEQUENT MONTHLY VARIABLE ANNUITY PAYMENTS
 
     The dollar amount of the first monthly variable annuity payment, determined
as above, is divided by the monetary value of an Annuity Unit as of the date of
retirement to fix the number of Annuity Units represented by the annuity
benefit. The number of Annuity Units, so determined, remains fixed thereafter
throughout the payment period. The dollar amount of the second monthly variable
annuity payment, due as of the first day of the month following retirement, is
determined by multiplying the fixed number of Annuity Units by the monetary
value of an Annuity Unit as of the due date of the second payment. This same
procedure is then followed to determine the monetary value of each succeeding
monthly variable annuity payment.
 
     On each Valuation Date, a net investment factor is determined from the
investment performance of the assets of Separate Account (B) during the period
since the last Valuation Date. Such factor is equal
 
                                       30
<PAGE>   33
 
to the value of an Accumulation Unit at the end of the period, divided by the
value on the preceding Valuation Date, carried to the nearest one hundred
thousandth. The net investment factor is determined after the deduction for any
taxes and for investment advisory fees and services as described above.
 
     The value of an Annuity Unit was established at $1.00000 ($1) on June 30,
1966. The monetary value of an Annuity Unit is redetermined for the entire month
as of the first day of each calendar month by multiplying the value of an
Annuity Unit on the first day of the preceding month by the ratio of the
Accumulation Unit value for the 15th day of the preceding month to the
Accumulation Unit value for the 15th day of the second preceding month, and
dividing the result by a monthly interest factor equivalent to the assumed net
investment rate (or the next working day if the 15th falls on a Saturday, Sunday
or holiday).
 
     The dollar amount of each monthly payment under a variable annuity will
fluctuate with the changing value of an Annuity Unit. The Annuity Unit value
will go up or down each month, depending on whether the actual effective
investment return for that month is at an annual rate which is greater than or
less than the assumed investment rate.
 
EXAMPLES
 
     The computation of the amounts payable under a variable annuity may be
illustrated by the following two examples, using unisex annuity tables. In each
case, assume a participant retired on January 1, 1999 at age 65. The participant
had on the date of retirement 15,000 Accumulation Units. The monetary value of
an Accumulation Unit as of December 15, 1998 was $20.010614. The total value of
the participant's account was therefore $300,159.21.
 
          - 403(B) PLAN CONTRACT.  Assume the participant selected Option
            2--Life Ten Years Certain. See "Annuities--Annuity Options--403(b)
            Plans". Both graded deduction and level deduction 403(b) Plan
            Contracts provide an annuity rate of $6.34 for a participant age 65,
            where Option 2 has been selected. The total value of the account
            $300,159.21, was therefore divided by $1,000 and multiplied by the
            annuity rate of $6.34 to obtain the initial monthly payment,
            $1,903.01. (It is assumed that no premium tax was applicable in this
            instance). Continuing this example, the monetary value of an Annuity
            Unit on the date of retirement was $6.692787. This was divided into
            $1,903.01 to obtain the quantity 284.337361 the number of Annuity
            Units represented by this benefit. This number of Annuity Units will
            remain fixed for the duration of the annuity payments. The second
            monthly payment, to be made on February 1, 1999, would be found by
            multiplying the number of Annuity Units by the monetary value of an
            Annuity Unit on that date. This was $7.348846. The dollar amount of
            the second payment would have been times 284.337361 or $2,089.55.
            Each succeeding monthly payment for this annuity would be determined
            in the same manner, being related in turn to the monetary value of
            an Annuity Unit on the date the payment is due. Again, the value of
            an Annuity Unit on that date will be found from the value on the
            first day of the preceding month, adjusted for investment experience
            and assumed interest for the period from the 15th day of the second
            preceding month to the 15th day of the preceding month (or the next
            working day if the 15th falls on a Saturday, Sunday or holiday).
 
          - HR-10 PLAN CONTRACT.  Assume the participant selected Option 1--Life
            Ten Years Certain. The HR-10 Plan Contract provides an annuity rate
            of $6.34 for a participant age 65, where Option 1 has been selected.
            The total value of the account, $300,159.21, was therefore divided
 
                                       31
<PAGE>   34
 
         by $1,000 and multiplied by the annuity rate of to obtain the initial
         monthly payment, $1,903.01. (It is assumed that no premium tax was
         applicable in this instance). Continuing this example, the monetary
         value of an Annuity Unit on the date of retirement was $6.692787. This
         was divided into $1,903.01 to obtain the quantity 284.337361, the
         number of Annuity Units represented by this benefit. This number of
         Annuity Units will remain fixed for the duration of the annuity
         payments. The second monthly payment, to be made on February 1, 1999,
         would be found by multiplying the number of Annuity Units by the
         monetary value of an Annuity Unit on that date. This was $7.348846. The
         dollar amount of the second payment would have been 284.337361 times
         $7.348846 or $2,089.55 . Each succeeding monthly payment for this
         annuity would be determined in the same manner, being related in turn
         to the monetary value of an Annuity Unit on the date the payment is
         due. Again, the value of an Annuity Unit on that date will be found
         from the value on the first day of the preceding month, adjusted for
         investment experience and assumed interest for the period from the 15th
         day of the second preceding month to the 15th day of the preceding
         month (or the next working day if the 15th falls on a Saturday, Sunday
         or holiday).
 
ASSUMED INVESTMENT RATE
 
     The examples are based upon a assumed investment rate of 3 1/2%. Under the
03(b) Plan graded deduction Contract, the participant has the option to choose
an assumed investment rate of 3%, 3 1/2%, 4%, 4 1/2% or 5%. This option must be
selected at least 30 days prior to the date annuity payments are to begin. If an
assumed investment rate is not selected, then a 3 1/2% rate will be applied.
CAC, in special cases, may stipulate variable annuity premiums and reserves on
assumed investment rates other than 3 1/2% for HR-10 Plan Contracts. Each
special Contract of this character would have different monetary values for
Annuity Units.
 
     A higher assumed investment rate will tend to result in a higher initial
payment but a more slowly rising series of subsequent payments (or a more
rapidly falling series of subsequent payments when Accumulation Unit values are
declining). A lower assumed investment rate would have the opposite effect. If
the actual net investment rate is equal to the assumed investment rate, the
annuity payments will be level. The assumed investment rate is an actuarial
technique rather than a guarantee of a rate of return, and no assurances can be
given that the actual net investment rate will equal or exceed the assumed
investment rate.
 
                        BENEFITS ON DEATH OR WITHDRAWAL
 
403(B) PLANS
 
     Upon termination of Purchase Payments on his behalf, a participant under a
403(b) Plan will have the following options, subject to the conditions in the
Contract:
 
     -  The participant may elect to have his individual account applied to
       provide annuity payments beginning immediately under the selected
       annuity option.
 
     -  The participant may surrender his individual account and receive
       the value of the account. The value of the account will be computed
       from the value of an Accumulation Unit next to be determined after a
       written request for surrender is received at the principal office of
       CAC, CNA Plaza, Chicago, Illinois 60685. Payment will be made within
       seven days thereafter,
 
                                       32
<PAGE>   35
 
       without termination charge. Payments upon redemption may be more or less
       than the original cost of the Accumulation Units.
 
     -  The participant may leave his individual account in force under the
       Contract until his required beginning date (generally the April 1
       following the later of the year in which he reaches age 70 1/2 or,
       if he is not a Five Percent Owner with respect to the year he or she
       reaches age 70 1/2, the year in which he retires) and the account
       will continue to participate in the investment results of Separate
       Account (B). At his required beginning date, the participant must
       take an annuity or surrender his account and receive its value.
 
     -  If the individual participant moves to another employer which has
       similar group annuity contract in force with CAC, his individual
       account may be transferred to the other group annuity contract.
 
     Federal income taxes may be withheld from the taxable portion of any amount
distributed.
 
     On the death of a participant prior to retirement, the value of his
individual account will be paid to his beneficiary in a single sum; or, if the
beneficiary is the participant's surviving spouse, it may be left in Separate
Account (B) until the date the participant would have attained age 70 1/2; or it
may be applied under one of the annuity options under the Contract to provide a
lifetime annuity on a variable basis, providing the initial monthly annuity
payment is at least $25 in amount. The participant's entire interest must,
however, be distributed within five years after his death unless the beneficiary
is his spouse or if the beneficiary takes the benefit in the form of a lifetime
annuity that begins by the end of the year that contains the first anniversary
of the participant's death. In general, all death benefits are taxable as
ordinary income when received by the designated beneficiary or by the estate;
however, the participant's spouse may be eligible to elect to defer taxation on
such death benefit to the extent the spouse directs a rollover to an individual
retirement plan or makes a "tax-free" rollover contribution of such death
benefit (including the amount of taxes withheld on such benefit) within sixty
days after receipt thereof to an individual retirement plan.
 
HR-10 PLANS
 
     Under all plans except certain profit sharing plans, death benefits in the
form of a survivor annuity will generally be paid to the surviving spouse of a
vested or partially vested participant if the participant was married for at
least one year as of the date of his death (or less if the HR-10 Plan so
provides), unless the participant waives such a spousal annuity and his spouse
consents. The monthly amount of the spousal annuity will be the amount the
surviving spouse would have received under a qualified joint and survivor
annuity as defined in ERISA if the participant had retired on the day before his
death (or, in the case of a participant who dies before he became eligible to
retire, the amount the surviving spouse would have received under such an
annuity if the participant had survived to the earliest retirement age under the
plan, retired, and died the day after such retirement). Under certain defined
contribution plans, the monthly amount of the spousal annuity is the amount that
would be provided under an annuity purchased with 50% of the participant's
individual account under the Contract. Under certain profit sharing plans, the
surviving spouse to whom a participant was married for at least one year on the
date of his death (or less if the HR-10 Plan so provides) will receive the
entire value of the participant's individual account under the Contract unless
the surviving spouse consents to another named beneficiary.
 
     For participants who are unmarried or who were married less than a year (or
other applicable period under the HR-10 Plan) when they died, and for other
participants whose spouses consent to an alternative
                                       33
<PAGE>   36
 
form of distribution or to another named beneficiary, in the event of the death
of a participant prior to retirement, the beneficiary currently designated by
the participant will be entitled to the entire value of his individual account
under the Contract. The monetary value of his account will be determined at the
Valuation Date next following the date the notice of death is received at the
principal office of CAC, CNA Plaza, Chicago, Illinois 60685. Payments upon death
or withdrawal may be more or less than the total of the original purchase
payments.
 
     If permitted by the plan, the beneficiary may elect to have the value
applied to provide a variable income to the beneficiary under rates set forth in
the Contract.
 
     On the withdrawal of a participant from the plan prior to retirement due to
a termination of employment or to a termination of the plan itself, the
following options are available:
 
     (a)  A participant may, regardless of age, have his individual account
        applied to provide a variable annuity option under the Contract,
        subject to the minimums set forth therein and to the requirement
        that the participant's spouse, if any, must consent in writing to
        the distribution.
 
     (b)  A participant may, regardless of age, surrender his individual
        account and receive the value of the account computed as of the
        Valuation Date next after the date the request for surrender is
        received by CAC, subject to spousal consent as described in
        subparagraph (a) above if required under the Plan.
 
     (c)  A participant may, if his interest in Separate Account (B) on the
        date of withdrawal is at least $2,000, allow his individual account
        to remain in force under the Contract, and his individual account
        will continue to participate in the investment results of Separate
        Account (B).
 
     On subsequent retirement, such participant may, regardless of age, begin to
receive annuity payments under the option selected. At any time in the interim,
such participant may instead surrender his individual account in accordance with
(b) above.
 
     In lieu of the above options, and if permitted under the plan, any
participant may elect to have his individual account transferred to a fixed
annuity contract, whereupon options similar to those above will apply. There may
be a termination charge of 2% of the pro rata amount of the Purchase Payments
received under the Contract relating to the withdrawal before withdrawal with
respect to a lump sum withdrawal of part or all of the interest of a
Contractholder in a Contract.

                                 FEDERAL TAXES
 
FEDERAL TAX TREATMENT OF PARTICIPANTS
 
     403(B) PLANS.  Amounts representing contractually permitted Purchase
Payments under 403(b) Plans made on behalf of participants are not recognizable
as taxable income to participants at the time they are made. However, Purchase
Payments made pursuant to salary reduction agreements will be subject to Social
Security ("FICA") taxes and Federal Unemployment Compensation ("FUTA") taxes.
Increases in the value of a participant's individual account are not taxable to
the participant until annuity payments are received by him. Any Purchase
Payments in excess of applicable limitations under the Internal Revenue Code are
includable in income.
 
     All annuity payments received after retirement will be based on realized
and unrealized capital gains as well as amounts representing purchase payments
on behalf of a participant and the participant's pro rata share of investment
income. All such annuity payments will be taxed under Section 72 of the Internal
Revenue Code as ordinary income in the year of receipt to the extent that they
exceed the participant's Investment in the Contract. The Investment in the
Contract is the amount of Purchase Payments made by or on behalf of such
participant which are a part of his or her taxable income in the year in which
such payments are made; i.e., those which are not deductible. In general, the
participant's Investment in the Contract is divided by the expected number of
payments to be made under the Contract. The amount so computed constitutes the
Excludable Amount, which is the amount of each annuity payment considered a
return of capital in each year and therefore not taxable. The participant may
not recover tax-free more than his Investment in the Contract. Thus, if a
participant's payments continue to be made longer than expected, all amounts
received are taxable after the Investment in the Contract is recovered.
Similarly, if a participant dies before recovering his Investment in the
Contract, his estate is entitled to a deduction in the participant's last
taxable year for the unrecovered amount.
 
     The rules for determining the Excludable Amount are contained in Section 72
of the Internal Revenue Code, and require adjustment for payments required under
the Contract to be made, regardless of the participant's death, for a term of
years, and in the case of a joint and survivor annuity payable to a named
beneficiary following the death of the participant.
 
     Should the participant elect to receive his termination value in a lump sum
in lieu of annuity payments, the amount received in excess of his Investment in
the Contract will be taxed as ordinary income in the year received. If any
portion of the balance to the credit of a participant is payable to the
participant in an Eligible Rollover Distribution, the participant or his
surviving spouse will defer taxation to the extent he or she (1) has such
distribution paid directly to an individual retirement plan or another tax-
sheltered annuity which accepts such rollovers or (2) makes a "tax-free"
rollover contribution equal to the amount of such distribution received plus the
amount of taxes withheld on such distribution within sixty days after receipt of
the distribution to an individual retirement plan or another tax sheltered
annuity. (No direct or indirect rollover is permitted to a qualified pension or
profit sharing plan and a direct rollover may not be permitted if the amount of
the distribution is less than $200). All taxable distributions are generally
Eligible Rollover Distributions except annuities paid over life or life
expectancy, installments for a period of ten years or more and required minimum
distributions under Section 401(a)(9) of the Internal Revenue Code.
 
     LIMITS ON CONTRIBUTIONS.  The maximum deduction for Employer contributions
made to a qualified defined contribution plan is limited to 25% of compensation
(15% of compensation in the case of a stock bonus or profit sharing plan).
Nondeductible contributions are 10% excise-taxable to the Employer subject
                                       35
<PAGE>   38
 
to certain limitations. This excise tax does not apply to tax-exempt Employers
except with respect to unrelated business income tax. However, in general, the
sum of purchase payments by the Employer, forfeitures of other plan
participants, salary reduction contributions or elective deferrals, if any, and
an employee's voluntary nondeductible contributions may not exceed the lesser of
25% of compensation or $30,000 for any year. For certain 403(b) Plans, these
limitations may be modified at the election of the participant in the 403(b)
Plan.
 
     For HR-10 Plans, nondeductible voluntary Purchase Payments are permitted to
be made by participants if the plan so provides, but only where such privilege
is extended to all participants. Nondeductible voluntary Purchase Payments may
be made, but are subject to certain nondiscrimination requirements and plan
limits which vary from plan to plan. Additionally, elective deferrals may be
made, if permitted by the plan, in an annual amount of up to $10,000. For 403(b)
Plans, the annual limit on salary reduction contributions is $9,500. These
contributions are subject to certain non-discrimination rules.
 
     HR-10 PLANS.  For a self-employed individual, compensation may generally be
defined as earned income, determined after the plan contribution. Only the first
$160,000 of a person's compensation ($235,840 for certain participants in plans
maintained by state or local governments that are amended to reflect the
compensation limitation applicable to all other participants) may be taken into
account. Plans may specify that purchase payments be made at a rate less than
25%, and profit sharing plans may provide for the rate of contribution to be
established (as described below) each year. If the plan is a top heavy plan (as
described below), generally an annual purchase payment of 3% of compensation
must be made for all non-key employees.
 
     The maximum deduction for Purchase Payments to a defined benefit plan is
determined annually by an actuary, subject to minimum funding standards
established by the Internal Revenue Code. Generally, no purchase payments may be
made to fund a normal retirement benefit in excess of 100% of compensation or,
if less, $130,000 per year for an individual beginning at his Social Security
retirement age. If it is a top heavy defined benefit plan, certain minimum
benefits must be provided for non-key employees. The $130,000 per year limit is
prorated if the individual has less than ten years of participation in the plan
and is reduced actuarially if benefits begin before Social Security retirement
age.
 
     Special rules apply to all plans (corporate or self-employed) which
primarily benefit the Employer's key employees ("top heavy plans"). A plan is a
top heavy plan (1) if it is a defined contribution plan and the value of the
aggregate accounts of key employees is more than 60 percent of all the value of
the aggregate accounts under the plan for all employees, or (2) if it is a
defined benefit plan and the present value of the cumulative accrued benefits
under the plan for key employees is more than 60 percent of the present value of
the cumulative accrued benefits under the plan for all employees. All plans of
an Employer in which a key employee is a participant and all plans required to
be aggregated to satisfy the qualification requirements of Section 401(a) of the
Internal Revenue Code must be aggregated in determining whether a plan is top
heavy. If the aggregation group, taken as a whole, is top heavy, then each plan
in the group is a top heavy plan. Any other tax qualified plans of the Employer
that meet certain rules may, but need not be, so aggregated. In general, an
employee is considered a key employee if he is a 5% Owner or if he is (or was in
any of the 4 preceding years) (1) an officer of the Employer with annual
compensation of more than $65,000, (2) one of the 10 employees with annual
compensation of more than $30,000 who owns the largest interests in the
Employer, or (3) an owner of 1 percent or more of the stock, profits or capital
of the Employer which owner has annual compensation of more than $150,000.
 
                                       36
<PAGE>   39
 
     For limitation years beginning prior to January 1, 2000, if an Employer
maintains a defined contribution plan and a defined benefit plan, there are
aggregate limitations on the benefits and contributions that may be provided
under the combination of plans. The limitations are more restrictive for top
heavy plans and are most restrictive for super top heavy plans (that is, defined
contribution plans where more than 90% of aggregate account balances are for key
employees and defined benefit plans where more than 90% of the cumulative
accrued benefits are for key employees).
 
     DISTRIBUTIONS--HR-10 PLANS.  Similar treatment is accorded to self-employed
individuals and common-law employees with respect to distributions from a plan.
A lump sum distribution in a single taxable year after attainment of age 59 1/2,
or on account of death, or because of disability of a self-employed individual
or separation of a common-law employee from the service of the Employer, is
taxable in the following manner: Employee non-deductible contributions are
received tax-free (distributions are deemed to consist proportionally of
tax-free and taxable amounts, unless CAC has a separate record of amounts
attributable to pre-1987 non-deductible employee contributions, in which case
those amounts may be distributed tax free). Either a self-employed individual or
a common-law employee, if such person is over 59 1/2 and has been a participant
for at least five taxable years before the year of distribution, may elect to be
taxed on the distribution (other than accumulated deductible qualified voluntary
contributions) at the rate applicable to a single taxpayer, subject to special
five-year forward income averaging. A person may make such an election only
once. Special five-year averaging ceases to be available for years beginning
after December 31, 1999. For participants who were age 50 by January 1, 1986,
five year forward averaging is not available, but an election may be made to
preserve the federal income tax treatment of the distribution in effect prior to
1987, i.e., ten-year forward income averaging (using 1986 tax rates) may be used
instead of five-year averaging and the portion of the distribution attributable
to pre-1974 participation is taxable as long term capital gain at a 20% rate.
Alternatively, if any portion of the balance to the credit of a participant is
payable to the participant in an Eligible Rollover Distribution, a participant
or his or her surviving spouse may be eligible to defer taxation on such
distribution to the extent he or she (1) has such distribution paid directly to
an individual retirement plan or another qualified plan which accepts such
rollovers or (2) makes a "tax-free" rollover contribution equal to the amount of
such distribution received plus the amount of taxes withheld on such
distribution within sixty days after receipt of such distribution to an
individual retirement arrangement or to another qualified plan. A direct
rollover may not be permitted if the amount of the distribution is less than
$200. All taxable distributions are generally Eligible Rollover Distributions
except annuities paid over life or life expectancy, installments for a period of
ten years or more, required minimum distributions under Section 401(a)(9) of the
Internal Revenue Code, and certain hardship distributions from a 401(k) plan.
 
     DISTRIBUTIONS--403(B) AND HR-10 PLANS.  Distributions made to any
participant in an HR-10 Plan or 403(b) Plan prior to attainment of age 59 1/2
(unless the distribution is made on account of death, disability, separation
from service where the separation occurred during or after the calendar year in
which the participant attains age 55, certain medical expenses within the
deductible limits of the Internal Revenue Code, or as part of a series of annual
or more frequent annuity payments made after separation from service and at
least over the participant's life, or if the distribution is made to an
alternate payee pursuant to a QDRO) will generally be subject to a 10% tax in
addition to the otherwise applicable federal income tax. There is also a 50%
excise tax on the amount by which a distribution is less than the required
minimum distribution.
 
     The withholding of federal income taxes depends upon whether a distribution
is an Eligible Rollover Distribution. There is mandatory income tax withholding
of 20% of the amount of any Eligible Rollover
 
                                       37
<PAGE>   40
 
Distribution that is not paid in a direct rollover to another qualifying plan;
if such distribution is paid in a direct rollover to another qualifying plan,
there is no income tax withholding obligation. Federal income taxes will be
withheld from the taxable portion of any distribution that is not an Eligible
Rollover Distribution. Additional withholding will not be made for the 10%
additional tax on premature distributions; however the recipient may be
responsible for paying estimated taxes.
 
FEDERAL TAX STATUS OF SEPARATE ACCOUNT (B)
 
     Separate Account (B) is not qualified as a "regulated investment company"
under subchapter M of the Internal Revenue Code, as it is not taxed separately
from CAC. While Separate Account (B) is part of the total operations of CAC,
under existing federal income tax law, no taxes are payable on the investment
income and realized capital gains which are reinvested in Separate Account (B)
and which are taken into account in determining the value of the Accumulation
Unit and the value of the Annuity Unit and which are not distributed to
participants except as part of annuity payments.
 
     Both investment income and realized capital gains are accumulated and
reinvested.
 
     The investment results credited to a participant's account are not taxable
to the participant until benefits are received by him. At that time, there is no
distinction made between investment income and realized and unrealized gains in
determining either the amount of the participant's benefits, or the taxes paid
by the participant on these benefits. All payments generally are taxable to the
recipient as ordinary income as received. A participant may wish to consult a
tax adviser for more complete information.
 
EMPLOYEE RETIREMENT INCOME SECURITY ACT
 
     ERISA contains many provisions which may apply to certain annuity plans
described under Sections 403(b) and 401 of the Internal Revenue Code, including
those offered hereunder. Employers and Contractholders may be subject to many
requirements and duties, including reporting and disclosure requirements,
requirements regarding the form and timing of benefit payments, fiduciary
responsibilities (including investment responsibilities) and prohibitions on
certain transactions involving or affecting the assets of the plan. Failure to
comply with ERISA may result in exposure of the Contractholder or Employer to
civil and criminal sanctions.
 
     Certain modifications in the Contracts described in this prospectus may be
required from time to time by ERISA or other laws. Such modifications may be
made by CAC in accordance with provisions in the Contracts which permit CAC to
amend the Contracts to conform to applicable law. Contractholders and, in the
case of HR-10 Plans, Employers will be informed of any such modifications.
 
     As set forth in this prospectus, the HR-10 Plan Contracts described herein
are offered solely in connection with certain retirement plans which are
qualified under Section 401 of the Internal Revenue Code. These plans include
not only individually designed plans of various employers or associations of
employers but also certain plans which are generally described as master or
prototype plans. In general, master or prototype plans are plans sponsored by an
organization such as an insurance company or trade association. The sponsoring
organization obtains a master or prototype plan opinion letter from the Internal
Revenue Service which indicates that the form of the plan meets the requirements
of Section 401 of the Internal Revenue Code. Once the sponsoring organization
has obtained a master or prototype plan opinion letter, Employers may, in
certain cases, adopt the master or prototype plan form as their own
tax-qualified plan with the benefit of a prior Internal Revenue Service approval
of the master or prototype plan form. Prototype plans sponsored by CAC have been
adopted by some Employers.
                                       38
<PAGE>   41
 
     This prospectus does not furnish detailed information concerning the
requirements of ERISA or the Internal Revenue Code, and those requirements may
vary depending upon the particular circumstances regarding each Employer and
each Contractholder. Also, the foregoing descriptions under "Federal Tax
Treatment of Participants" apply under federal income tax laws in effect on
April 30, 1999, and the federal tax treatment of Participants may change. It is
therefore recommended that Employers, Contractholders and potential Purchasers
consult with counsel or other competent advisers regarding the impact of ERISA
and The Internal Revenue Code.
 
                                 LEGAL MATTERS
 
     Separate Account (B) is not involved in any pending legal proceedings. CAC
is involved in litigation arising in the ordinary course of its business.
Because of the nature of litigation, it is not possible to predict the outcome
of these actions; however, in the opinion of the management of CAC, such
litigation will not materially adversely affect the business or financial
position of CAC or Separate Account (B) or the ability of CAC to perform its
obligations under the Investment Advisory Agreement.
 
     Legal matters in connection with the offering made hereby have been passed
upon by Lynne Gugenheim, Vice President and Associate General Counsel of CAC.
 
                            REPORTS TO PARTICIPANTS
 
     Semi-annually, CAC will provide a financial report to each participant
covering the most recent six months or calendar year, as applicable. These
reports will include general information on Separate Account (B), including a
schedule of its investments in securities as of the close of the applicable
period. Also provided will be a statement of the participants' equity in
Separate Account (B), showing the changes therein for the period reported on
Reports issued as of the close of a calendar year will contain financial
statements which have been audited by Separate Account (B)'s independent
auditors.

     We have audited the financial statements of Continental Assurance Company
Separate Account (B) (a separate account of Continental Assurance Company, a
wholly-owned subsidiary of Continental Casualty Company, which is a wholly-owned
subsidiary of CNA Financial Corporation, an affiliate of Loews Corporation) as
of December 31, 1998 and 1997 and for each of the two years in the period ended
December 31, 1998, and the related schedule of investments as of December 31,
1998, and have issued our report dated February 13, 1999; such financial
statements, schedule and report are included in the 1998 Continental Assurance
Company Separate Account (B) Report to Participants and are incorporated herein
by reference. Our audits also included the financial highlights for each of the
ten years in the period ended December 31, 1998 presented herein on page 12.
This information is the responsibility of the Company's management. Our
responsibility is to express an opinion based on our audits. In our opinion,
such financial information, when considered in relation to the basic financial
statements taken as a whole, presents fairly, in all material respects, the

      outstanding stock of Casualty, CNA Plaza, Chicago, Illinois 60685, which,
      in turns, owns all of the outstanding stock of CAC.
 
 (2)  Prior to December 27, 1996 CLE, Inc., a wholly owned indirect subsidiary
      of Casualty, owned 63% of the non-voting preferred stock of 21EMI. On
      December 27, 1996, CLE, Inc. sold all of the 21EMI stock that it owned to
      a third party unaffiliated with Casualty. Since December 27, 1996, CLE,
      Inc. has had no interest in 21EMI.
 
     No Committee Member or officer receives any remuneration from Separate
Account (B). CAC pays Committee Members a fee for their service. The Committee
Member's fee is currently $10,000 per annum. CAC also reimburses Committee
Members for expenses incurred in attending meetings of the Committee. However,
no payments of fees or expenses are made to any Committee Member who is an
officer or employee of or special consultant to CAC, CNA Financial or any of
their affiliated companies. Therefore, neither Mr. Dubberke nor Ms. McGirr has
received or will receive any such payments. During 1998, there was no
reimbursement payable for expenses incurred by Committee Members.

CONTROL PERSONS AND PRINCIPAL HOLDERS OF SECURITIES
 
     As of February 26, 1999, no person was deemed to be in control of Separate
Account (B) or was known by either CAC or Separate Account (B) to own of record
or beneficially 5% or more of the Accumulation Units of the Separate Account.
None of the officers or Members of the Committee of Separate Account (B) own any
Accumulation Units of Separate Account (B).
 
                          INVESTMENT ADVISORY SERVICES
 
     All of the voting securities of CAC are owned by Casualty, a stock casualty
insurance company organized under the Illinois Insurance Code, the home office
of which is located at CNA Plaza, Chicago, Illinois 60685. All of the voting
securities of Casualty are owned by CNA Financial, a Delaware corporation, CNA
Plaza, Chicago, Illinois 60685. Loews Corporation, a Delaware corporation, 667
Madison Avenue, New York, New York 10021-8087, with interests in insurance,
hotels, watches and other timing devices, drilling rigs and tobacco, owned
approximately 85% of the outstanding voting securities of CNA Financial as of
December 31, 1998. Laurence A. Tisch, the Chairman of the Board, Co-Chief
Executive Officer and a director of Loews Corporation and Chief Executive
Officer and a director of CNA Financial and his brother, Preston R. Tisch,
President, Co-Chief Executive Officer and a director of CNA Financial and Loews
Corporation, owned, in the aggregate, approximately 31% of the outstanding
common stock of Loews Corporation as of December 31, 1998. Therefore, they may
be deemed to be parents of
 
                                        4
<PAGE>   52
 
Loews Corporation, and thus of CNA Financial Corporation and CAC, within the
meaning of the federal securities laws.
 
     Pursuant to the Investment Advisory Agreement, CAC makes quarterly
withdrawals from Separate Account (B) at an annual rate of 0.5% of the average
daily net asset value of Separate Account (B) for providing investment advisory
services, and at an additional annual rate of 0.33% of the average daily net
asset value of Separate Account (B) as a service fee for bearing the following
expenses of Separate Account (B): costs and expenses incident to compliance with
federal and state regulations applicable to any public offering of Accumulation
Units in Separate Account (B); expenses related to printing and distributing
prospectuses and statements of additional information to persons who, at the
time of such distribution, are participants in Separate Account (B); SEC
registration; charges and expenses for custodian services (other than charges
and expenses relating to the lending of portfolio securities); charges and
expenses of independent auditors and legal counsel; expenses of meetings of the
participants and of the Committee (including the preparation and distribution of
proxy statements and semi-annual and annual reports); and bookkeeping and
postage expenses (other than postage expenses relating to the mailing of
prospectuses and statements of additional information to persons who, at the
time of such mailing, are not participants in Separate Account (B) or relating
to the mailing of sales literature). In the event that the total amount of the
expenses covered by the service fee is less than the amount of such service fee,
the difference will accrue to CAC as a profit. If such expenses are greater than
the fee, the difference will accrue to CAC as a loss. Under its Investment
Advisory Agreement with Separate Account (B), CAC is permitted to make such
withdrawals on a monthly basis instead of on a quarterly basis, but to date CAC
has nevertheless consented to being paid quarterly. Separate Account (B) has
incurred the following investment advisory and service fees payable to CAC:
1998, $1,365,230; 1997, $1,180,321; and 1996, $933,963. Separate Account (B)
pays all expenses incurred in connection with the lending of portfolio
securities.
 
     The Investment Advisory Agreement may be terminated at any time by either
party, without the payment of any penalty, on sixty days' prior written notice.
The Investment Advisory Agreement continues in effect from year to year so long
as it is approved at least annually by the vote of a majority of the Committee
Members who are not parties to the Agreement or interested persons (as defined
in the 1940 Act) of any such party, cast in person at a meeting called for the
purpose of voting upon such approval.
 
     In the event the Investment Advisory Agreement is terminated and another
investment adviser cannot be found, the assets of Separate Account (B) may be
liquidated. In the event of such liquidation, the interest of any retired
participant in Separate Account (B) will be transferred by CAC to its regular
reserves, and CAC will pay a fixed annuity for the lifetime of the participant
in the same form as the variable annuity held. Participants who are not retired
will be offered an option to receive a lump sum settlement or to receive an
immediate or deferred fixed annuity. Under Section 1035(a)(3) of the Internal
Revenue Code of 1986, no gain or loss will be recognized on the exchange of a
variable annuity for the fixed annuity. Liquidation of Separate Account (B) upon
termination of the Investment Advisory Agreement may have adverse federal income
tax consequences for a participant electing to receive a lump sum settlement
since the full amount of the settlement received will be taxable as ordinary
income realized in the year of receipt.
 
     Under separate agreements with Separate Account (B), CAC acts as principal
underwriter and performs all sales and administrative functions relative to
Separate Account (B) and the variable annuity contracts of Separate Account (B).
The amounts earned by CAC for sales and administrative functions rendered to
Separate Account (B) for each of the years 1998, 1997, and 1996 were $10,428,
$11,417, and
                                        5

$12,704, respectively. The agreement covering sales and administrative services
does not cover the services covered by the Investment Advisory Agreement.
 
     CAC has two affiliates, CNA Investor Services, Inc. ("Investor Services"),
(the successor by merger to CNA Securities Corp.), and Hedge Investor Services,
Inc. ("Hedge Services") which are members of the National Association of
Securities Dealers, Inc. CAC and Separate Account (B) are parties to an
agreement under which Separate Account (B) receives credit from CAC in the form
of a reduction of the investment advisory fee to the extent that services of
Investor Services are utilized in connection with Separate Account (B)'s
portfolio transactions. In 1975, the securities laws were amended to abolish
fixed brokerage commissions on securities transactions. Prior to such changes,
it was mutually advantageous to Separate Account (B) and to CNA Securities Corp.
for the services of CNA Securities Corp. to be utilized in connections with
certain of Separate Account (B)'s portfolio transactions. The advantage of such
arrangement was reduced significantly by the above-mentioned changes in the
securities laws. Separate Account (B) had no transactions with either Investor
Services or Hedge Services during 1998, or with Investor Services during 1997
and 1996.
 
                  IMPACT OF YEAR 2000 ON SEPARATE ACCOUNT (B)
 
   
     The widespread use of computer programs, both in the United States and
internationally, that rely on two digit date fields to perform computations and
decision making functions may cause computer systems to malfunction when
processing information involving dates beginning in 1999. Such malfunctions
could lead to business delays and disruptions. Separate Account (B) does not
maintain any systems. Instead, it relies on the systems of its investment
advisor, CAC, and third party vendors. Separate Account (B) has a plan under
which it reviews periodically the progress that these parties are making on this
issue. To date, CNA Financial, on behalf of CAC, has certified internally as
Year 2000 ready all of the systems used by CAC in its duties as investment
advisor and administrative agent for Separate Account (B). Based on its current
assessment, CNA Financial estimates that the total cost to replace and upgrade
its systems to accommodate Year 2000 processing will be approximately $60 to $70
million. As of December 31, 1998, CNA Financial had spent approximately $59
million on Year 2000 readiness matters.
    
 
     CNA Financial has also received statements of Year 2000 compliance from
certain of key business partners: The Chase Manhattan Bank (Separate Account
(B)'s custodian bank); Bloomberg L.P. (the system used for trade entry); MAXIMIS
(Separate Account (B)'s accounting system) and The Depository Trust Company (the
book-entry depository used to record ownership of securities). Separate Account
(B) believes that the systems on which it relies do not have any remaining
exposure to the Year 2000 problem and, therefore, Separate Account (B) does not
have material exposure to the Year 2000 problem. However, due to the
interdependent nature of computer systems, there may be an adverse impact on
Separate Account (B) if banks, vendors, various governmental agencies and other
business partners fail to successfully address the Year 2000. To mitigate this
impact, CNA Financial is communicating with these various entities to coordinate
Year 2000 conversion.
 
     In addition, CNA Financial has developed business resumption plans to
ensure that it and Separate Account (B) are able to continue critical processes
through other means in the event that it becomes necessary to do so. Formal
strategies have been developed within each business unit and support
organization to include appropriate recovery processes and use of alternative
vendors. More than 200 strategies have been developed by CNA Financial to
address recovery plans for approximately 400 processes. These plans are being
updated quarterly.

                              SECURITIES CUSTODIAN
 
     The custodian of Separate Account (B)'s portfolio securities is The Chase
Manhattan Trust Company of Illinois, 10 South LaSalle Street, Chicago, Illinois
60603.
 
     The custodian does not perform any managerial or policy-making functions
for Separate Account (B).
 
                              INDEPENDENT AUDITORS
 
     The Committee has appointed Deloitte & Touche LLP, Two Prudential Plaza,
180 North Stetson Avenue, Chicago, Illinois, as auditors to audit the financial
statements of Separate Account (B). They also audit the Schedule of Investments
and the Financial Highlights of Separate Account (B). In addition, Deloitte &
Touche LLP has been appointed to audit the consolidated financial statements of
CAC.
 
                             BROKERAGE ALLOCATIONS
 
     Officers and employees in the Investment Department of CAC are primarily
responsible for making portfolio decisions for Separate Account (B) and for
placing brokerage business of Separate Account (B). Separate Account (B) has
paid the following brokerage fees and commissions in connection with portfolio
transactions: 1998, $538,717; 1997, $464,745; and 1996, $371,335.
 
     In selecting brokers to execute portfolio transactions, CAC's primary
criterion is the expected ability of such brokers to make the best possible
execution on orders. If several brokers are expected to be able to provide
equally good execution, preference is given to those brokers who provide
statistical research, assistance in pricing portfolio securities or other
services. Commissions on all transactions are negotiated, and the primary basis
of the commission agreed to by CAC is the quality of execution. Research
services, to the extent provided to CAC, may be used by CAC in servicing its
other accounts and not all such services are used in connection with Separate
Account (B).
 
     In connection with the purchase and sale of portfolio securities for
Separate Account (B), CAC does not bunch orders for such transactions with
orders for other accounts under the management of Loews, CNA Financial, CAC or
other subsidiaries of CNA Financial unless such other accounts are registered
investment companies and unless such bunching would not have adverse
consequences for Separate Account (B) and such other accounts. Under no
circumstances are orders bunched with orders for CAC's own account or for the
account of Loews Corporation, CNA Financial or other subsidiaries of CNA
Financial. No bunching of orders occurred during 1998.
 
                        CALCULATION OF PERFORMANCE DATA
 
     In computing the end-of-period values listed below of a hypothetical
investment in Separate Account (B), average annual total return ("Average
Return") was calculated by dividing the ending unit value by the beginning unit
value raised to the l/nth power and then subtracting one (with "n" equaling the
number of years). Fees based on a percentage of the purchase payment were
subtracted at the beginning of the specified period. Annual account fees, where
applicable, were deducted at the end of each year.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholder
Continental Assurance Company
 
     We have audited the accompanying consolidated balance sheets of Continental
Assurance Company (a wholly-owned subsidiary of Continental Casualty Company,
which is a wholly-owned subsidiary of CNA Financial Corporation, an affiliate of
Loews Corporation) as of December 31, 1998 and 1997 and the related statements
of consolidated operations, stockholder's equity, and cash flows for each of the
three years in the period ended December 31, 1998. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Continental Assurance Company
as of December 31, 1998 and 1997, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1998 in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1. SIGNIFICANT ACCOUNTING POLICIES:
 
BASIS OF PRESENTATION
 
   
     Continental Assurance Company ("CAC") is a wholly-owned subsidiary of
Continental Casualty Company ("Casualty") which is wholly-owned by CNA Financial
Corporation ("CNA Financial"). Loews Corporation owns approximately 85% of the
outstanding common stock of CNA Financial. The operating subsidiaries of CAC
consist of Valley Forge Life Insurance Company ("VFL"), Convida Holdings, Ltd.,
CNA Health Partners, Inc. and CNA Life Insurance Company of Canada.
    
 
   
     The accompanying consolidated financial statements have been prepared in
conformity with generally accepted accounting principles ("GAAP"). Certain
amounts applicable to prior years have been reclassified to conform to
classifications followed in 1998. All significant intercompany amounts have been
eliminated.
    
 
     The preparation of financial statements in conformity with GAAP requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.
 
INSURANCE
 
     Premium revenue--Revenues on universal life-type contracts are comprised of
contract charges and fees which are recognized over the coverage period.
Accident and health insurance premiums are earned ratably over the terms of the
policies after provision for estimated adjustments on retrospectively rated
policies and deductions for ceded insurance. Other life insurance premiums and
annuities are recognized as revenue when due after deductions for ceded
insurance.
 
   
     Future policy benefit reserves--Reserves for traditional life insurance
products (whole and term life products) are computed based upon the net level
premium method using actuarial assumptions as to interest rates, mortality,
morbidity, withdrawals and expenses. Actuarial assumptions include a margin for
adverse deviation and generally vary by plan, age at issue and policy duration.
Interest rates range from 3% to 9%, and mortality, morbidity and withdrawal
assumptions reflect CAC and industry experience prevailing at the time of issue.
Expense assumptions include the estimated effects of inflation and expenses
beyond the premium paying period. Reserves for universal life-type contracts are
equal to the account balances that accrue to the benefit of the policyholders.
Interest crediting rates ranged from 4.30% to 7.25% for the three years ended
December 31, 1998.
    
 
     Claim reserves--Claim reserves include provisions for reported claims in
the course of settlement and estimates of unreported claims based upon past
experience.
 
   
     Reinsurance--CAC assumes and cedes insurance with other insurers and
reinsurers. CAC utilizes reinsurance arrangements to limit its maximum loss,
provide greater diversification of risk and minimize exposures on larger risks.
The reinsurance coverages are tailored to the specific risk characteristics of
each product line with CAC's retained amount varying by type of coverage. CAC's
reinsurance includes quota

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--CONTINUED
 
NOTE 1.--(CONTINUED):
share, yearly renewable term and facultative programs. Amounts recoverable from
reinsurers are estimated in a manner consistent with the claim or policy reserve
liability.
 
     Deferred acquisition costs--Life insurance acquisition costs are
capitalized and amortized based on assumptions consistent with those used for
computing policy benefit reserves. Acquisition costs on traditional life
business are amortized over the assumed premium paying periods. Universal life
and annuity acquisition costs are amortized in proportion to the present value
of the estimated gross profits over the products' assumed duration. To the
extent that unrealized gains or losses on available-for-sale securities would
result in an adjustment of deferred policy acquisition costs had those gains or
losses actually been realized, the related unamortized deferred policy
acquisition costs are recorded as an adjustment of the unrealized gains or
losses included in stockholder's equity.
 
     Participating business--Participating business represented 0.5%, 0.7% and
0.5% of gross life insurance in force and 0.7%, 0.7% and 0.7% of premium income
for 1998, 1997 and 1996, respectively. Participating policyholders' equity is
determined by allocating 90% of the net income or loss and unrealized investment
gains or losses related to such business as allowed by applicable laws, less
dividends determined by the Board of Directors. Revenues and benefits and
expenses include amounts related to participating policies; the net income or
loss allocated to participating policyholders' equity is a component of benefits
and expenses.
 
   
     Separate Account business--CAC writes certain investment and annuity
contracts. The supporting assets and liabilities of these contracts and policies
are legally segregated and reflected as assets and liabilities of Separate
Account business. CAC guarantees principal and a specified return to the
contract holders on approximately 64% and 74% of the Separate Account business
at December 31, 1998 and 1997, respectively. Substantially all assets of the
Separate Account business are carried at fair value. Separate account
liabilities are carried principally at contract values.
    
 
INVESTMENTS
 
   
     Valuation of investments--CAC classifies its fixed maturity securities
(bonds and redeemable preferred stocks) and its equity securities as
available-for-sale, and as such, they are carried at fair value. The amortized
cost of fixed maturity securities is adjusted for amortization of premiums and
accretion of discounts to maturity. Such amortization and accretion are included
in investment income.
    
 
   
     CAC accounts for its derivative securities under the fair value method.
Under this method the derivative securities are recorded at fair value at the
reporting date with changes in fair value reflected in realized investment gains
and losses. CAC's derivatives are made up of interest rate caps, futures,
forwards, commitments to purchase securities and options and are classified as
other invested assets.
    
 
     Mortgage loans are carried at unpaid principal balances, including
unamortized premium or discount. Real estate is carried at depreciated cost.
Policy loans are carried at unpaid balances. Short-term investments, which have
an original maturity of one year or less, are carried at amortized cost, which
approximates fair value.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--CONTINUED
 
NOTE 1.--(CONTINUED):
   
     Investment gains and losses--All securities transactions are recorded on
the trade date. Realized investment gains and losses are determined on the basis
of the amortized cost of the specific securities sold. Unrealized investment
gains and losses on fixed maturity securities and equity securities are
reflected as part of Stockholder's equity (accumulated other comprehensive
income), net of applicable deferred income taxes and participating
policyholders' interest. Investments are written down to estimated fair values
and losses are charged to income when a decline in value is considered to be
other than temporary.
    
 
   
     Securities lending activities--CAC has a securities lending program where
securities are loaned to third parties, primarily major brokerage firms.
Borrowers of these securities must deposit 100% of the fair value of the
securities if the collateral is cash, or 102% if the collateral is securities.
Cash deposits from these transactions are invested in short-term investments
(primarily commercial paper). CAC continues to receive the interest on the
loaned debt, as beneficial owner, and accordingly, loaned debt securities are
included in fixed maturity securities.
    
 
INCOME TAXES
 
     The provision for income taxes includes deferred taxes, resulting from
temporary differences between the financial statement and tax return basis of
assets and liabilities under the liability method. Temporary differences
primarily relate to insurance reserves, investment valuation differences, net
unrealized investment gains/losses and deferred acquisition costs.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment are carried at cost less accumulated depreciation.
Depreciation is based on the estimated useful lives of the various classes of
property and equipment and determined principally on accelerated methods. The
cost of maintenance and repairs is charged to income as incurred; major
improvements are capitalized.
 
   
ACCOUNTING BY INSURANCE AND OTHER ENTERPRISES FOR INSURANCE-RELATED ASSESSMENTS
    
 
   
     In December 1997, the American Institute of Certified Public Accountants'
Accounting Standards Executive Committee issued Statement of Position (SOP)
97-3, "Accounting by Insurance and Other Enterprises for Insurance-Related
Assessments." SOP 97-3 requires that entities recognize liabilities for
insurance-related assessment when all of the following criteria have been met:
an assessment has been imposed or it its probable that occurred on or before the
date of the financial statements; and the amount of the assessment can be
reasonably estimated. This SOP is effective for financial statements for fiscal
years beginning after December 15, 1998. The effects of this SOP will result in
CAC recording a pre-tax charge in 1999 between $2 million and $5 million as a
cumulative effect of a change in accounting principle.

NOTE 2.--(CONTINUED):
     High yield securities are bonds rated as below investment grade by bond
rating agencies and other unrated securities which, in the opinion of
management, are below investment grade (below BBB). Carrying values of high
yield securities in the general account were $426.5 million and $407.0 million
at December 31, 1998 and 1997, respectively. Net unrealized gains on high yield
securities, included in the general account, were $5.0 million and $2.5 million
at December 31, 1998 and 1997, respectively.
 
   
     At December 31, 1998, total Separate Account investments excluding cash
amounted to $5.1 billion with taxable fixed maturities representing
approximately 81% of the Separate Accounts' portfolio. Approximately 64% and
74%, at December 31, 1998 and 1997, respectively, of the Separate Account
investments were used to fund guaranteed investment contracts (GICs) for which
CAC guarantees principal and a specified return to the contract holders. The
duration of fixed maturities included in the GIC portfolio is matched to
approximate the corresponding payout pattern of the liabilities of the GIC
contracts.
    
 
     All fixed maturities in the GIC portfolio were carried at fair value and
amounted to $3.2 billion and $3.8 billion at December 31, 1998 and 1997,
respectively. At December 31, 1998 and 1997, net unrealized gains on fixed
maturities in the GIC portfolio amounted to approximately $64.3 million and
$71.2 million, respectively. The gross unrealized gains and losses for the fixed
maturities portfolios at December 31, 1998, were $84.3 million and $20.0
million, respectively, compared to $86.7 million and $15.5 million,
respectively, at December 31, 1997.
 
     High yield securities in the guaranteed Separate Account portfolio were
carried at fair value totaling $268.9 million and $310.3 million at December 31,
1998 and 1997, respectively. Net unrealized losses on high yield securities held
in such Separate Accounts were $8.8 million and $1.2 million at December 31,
1998 and 1997, respectively.

NOTE 4. FINANCIAL INSTRUMENTS:
 
   
     In the normal course of business, CAC invests in various financial assets,
incurs various financial liabilities, and enters into agreements involving
derivative securities, including off-balance sheet financial instruments.
    
 
     Fair values are required to be disclosed for all financial instruments,
whether or not recognized in the consolidated balance sheets, for which it is
practicable to estimate that value. In cases where quoted market prices are not
available, fair values may be based on estimates using present value or other

valuation techniques. These techniques are significantly affected by the
assumptions used, including the discount rates and estimates of future cash
flows. Potential taxes and other transaction costs have not been considered in
estimating fair value. The estimates presented herein are subjective in nature
and are not necessarily indicative of the amounts CAC could realize in the
current market exchange.
    
 
   
     Non-financial instruments such as real estate, deferred acquisition costs,
reinsurance receivables, property and equipment, deferred income taxes and
insurance reserves are excluded from fair value disclosure. Thus, the total fair
value amounts cannot be aggregated to determine the underlying economic value of
CAC.
    
 
   
     The carrying amounts reported in the consolidated balance sheet approximate
fair value for cash, short-term investments, premium and other insurance
receivables, accrued investment income, receivables for securities sold,
securities sold under repurchase agreements, payables for securities purchased
and certain other assets and other liabilities because of their short-term
nature. Accordingly, these financial instruments are not listed in the table
below. The carrying amounts and estimated fair values of CAC's other financial
instrument assets and liabilities are listed in the following table. Derivative
instruments are shown in a separate table.

NOTE 4.--(CONTINUED):
   
     The following methods and assumptions were used by CAC in estimating the
fair value for the above financial instruments:
    
 
          Fixed maturity securities and equity securities are based on quoted
     market prices, where available. For securities not actively traded, fair
     values are estimated using values obtained from independent pricing
     services, costs to settle or quoted market prices of comparable instruments
 
          The fair values for mortgage loans and policy loans are estimated
     using discounted cash flow analyses at interest rates currently offered for
     similar loans to borrowers with comparable credit ratings. Loans with
     similar characteristics are aggregated for purposes of the calculations.
 
          Valuation techniques to determine fair value of other invested assets
     and other Separate Account business assets consist of discounted cash flows
     and quoted market prices of (a) the investments, (b) comparable instruments
     or (c) underlying assets of the investments.
 
          Premium deposits and annuity contracts are valued based on cash
     surrender values and the outstanding fund balances.
 
   
          CAC's long-term debt represents floating rate tax exempt bonds with
     interest rates determined monthly and thus approximates fair value.
    
 
          The fair values for guaranteed investment contracts and deferred
     annuities of the Separate Account business are estimated using discounted
     cash flow calculations, based on interest rates currently being offered for
     similar contracts with similar maturities. The fair values of the
     liabilities for variable Separate Account business are based on the quoted
     market values of the underlying assets of each variable Separate Account.
     The fair value of other Separate Account business liabilities approximates
     their carrying value.
 
DERIVATIVE FINANCIAL INSTRUMENTS
 
   
     CAC invests from time to time in derivative financial instruments primarily
to reduce its exposure to market risk. Financial instruments used for such
purposes may include interest rate caps, put and call options, commitments to
purchase securities, futures and forwards. CAC generally does not hold or issue
these instruments for trading purposes. CAC also uses derivatives to mitigate
the risk associated with its indexed group annuity contracts by purchasing S&P
500 futures contracts in a notional amount equal to the original customer
deposit.
    
 
     The gross notional principal or contractual amounts of derivative financial
instruments in the general account totaled $500.0 million at December 31, 1998
and 1997. The gross notional principal or contractual amounts of derivative
financial instruments in the Separate Accounts totaled $1,193.9 million and
$859.9 million at December 31, 1998 and 1997 respectively. The contract or
notional amounts are used to calculate the exchange of contractual payments
under the agreements and are not representative of the potential for gain or
loss on these agreements.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--CONTINUED
 
NOTE 4.--(CONTINUED):
   
     The fair values associated with derivative financial instruments are
generally affected by interest rates, equity stock prices and foreign exchange
rates. The credit exposure associated with these instruments is generally
limited to the unrealized fair value of the instruments and will vary based on
the credit worthiness of the counterparties. Although CAC is exposed to the
aforementioned credit risk, it does not expect any counterparty to fail to
perform as contracted based on the creditworthiness of the counterparties. Due
to the nature of the derivative securities, CAC does not require collateral.
    
 
   
     The fair value of derivatives generally reflects the estimated amounts that
CAC would receive or pay upon termination of the contracts at the reporting
date. Dealer quotes are available for substantially all of CAC's derivatives.
For securities not actively traded, fair values are estimated using values
obtained from independent pricing services, costs to settle or quoted market
prices of comparable instruments.
    
 
     A summary of the aggregate notional or contractual amounts and estimated
fair values of these instruments at December 31, 1998 and 1997, is presented
below.

NOTE 4.--(CONTINUED):
purchase and sell a specific quantity of a commodity, government security,
foreign currency or other financial instrument at a price specified at contract
inception, with delivery and settlement at a specified future date.
 
     Commitments to purchase government and municipal securities are a
commitment to purchase securities in the future at a predetermined price.
 
     Options are contracts that grant the purchaser, for a premium payment, the
right, but not the obligation, to either purchase or sell a financial instrument
at a specified price within a specified period of time.
 
     An interest rate cap consists of a guarantee given by the issuer to the
purchaser in exchange for the payment of a premium. This guarantee states that
if interest rates rise above a specified rate, the issuer will pay to the
purchaser the difference between the then current market rate and the specified
rate on the notional principal amount. The notional principal amount is not
actually borrowed or repaid.
 
NOTE 5. STATUTORY CAPITAL AND SURPLUS (UNAUDITED):
 
   
     Statutory capital and surplus and net income for CAC are determined in
accordance with accounting practices prescribed or permitted by the Illinois
Insurance Department. Prescribed statutory accounting practices are set forth in
a variety of publications of the National Association of Insurance Commissioners
("NAIC") as well as state laws, regulations and general administrative rules.
CAC has no material permitted accounting practices. Statutory net income (loss)
was $(56.7) million, $42.6 million and $57.7 million for the years ended
December 31, 1998, 1997 and 1996, respectively. Statutory capital and surplus
for CAC was $1.1 billion and $1.2 billion at December 31, 1998 and 1997,
respectively. Statutory capital and surplus of $34.5 million at December 31,
1998 and 1997, was appropriated by the Board of Directors, under regulatory
formula, to fund excess group losses due to an epidemic or disaster, if
necessary. The payment of dividends by CAC to Casualty, without prior approval
of the Illinois Insurance Department is limited to formula amounts.
Approximately $110.9 million and $122.4 million at December 31, 1998 and 1997,
respectively, was not subject to prior Insurance Department approval.

NOTE 7. BENEFIT PLANS:
 
   
     CAC has no employees as it has contracted with Casualty for services
provided by Casualty employees. As Casualty is a wholly-owned subsidiary of CNA
Financial, all Casualty employees are covered by CNA Financial's benefits plans.
The plans of CNA Financial are discussed below.
    
 
PENSION PLAN
 
   
     CNA Financial has noncontributory pension plans covering all full-time
employees age 21 or over who have completed at least one year of service.
Casualty is included in the CNA Employees' Retirement Plan and CAC is allocated
their proportionate share of these expenses. While the benefits for the plans
vary, they are generally based on years of credited service and the employee's
highest sixty consecutive months of compensation. The net pension cost allocated
to CAC was $10.9 million, $7.8 million and $7.5 million for the years ended
December 31, 1998, 1997 and 1996, respectively.
    
 
POSTRETIREMENT HEALTH CARE AND LIFE INSURANCE BENEFITS
 
   
     CNA Financial provides certain health care benefits for eligible retirees,
through age 64, and provides life insurance and reimbursement of Medicare Part B
premiums for all eligible retired persons. CNA Financial funds benefit costs
principally on the basis of current benefit payments. Net postretirement benefit
cost allocated to CAC was $5.2 million, $4.3 million and $2.8 million for the
years ended December 31, 1998, 1997 and 1996, respectively.
    
 
SAVINGS PLAN
 
   
     Casualty is included in the CNA Employees' Savings Plan, which is a
contributory plan that allows employees to make regular contributions of up to
6% of their salary. CNA Financial contributes an additional amount equal to 70%
of the employee's regular contribution. Employees may also make an additional
contribution of up to 10% of their salaries for which there is no additional
contribution by CNA Financial. CAC is allocated its proportionate share of CNA
Employees' Savings Plan expenses. CNA

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--CONTINUED
 
NOTE 7.--(CONTINUED):
   
Financial contributions allocated to and expensed by CAC for the Savings Plan
were $2.2 million, $2.0 million and $2.3 million for the years ended December
31, 1998, 1997 and 1996, respectively.
    
 
NOTE 8. INCOME TAXES:
 
   
     CAC and its domestic life insurance subsidiary are taxed under the
provisions of the Internal Revenue Code, as applicable to life insurance
companies, and are included in the consolidated Federal income tax return with
CNA Financial and its eligible subsidiaries (CNA Tax Group), which in turn is
included in the consolidated Federal income tax return of Loews and its eligible
subsidiaries. The Federal income tax provision of CAC is computed on a
stand-alone basis, as if CAC and its domestic life insurance subsidiary were
filing its own separate consolidated tax return.
    
 
   
     CAC and its domestic life insurance subsidiary maintain a special tax
memorandum account designated as the "Shareholder's Surplus Account." Dividends
from this account may be distributed to the shareholder without resulting in any
additional tax. The amount in the Shareholder's Surplus Account was $1,519.8
million and $1,419.9 million at December 31, 1998 and 1997, respectively.
    
 
   
     Significant components of CAC's deferred tax assets and liabilities as of
December 31, 1998 and 1997 and are shown in the table below:

NOTE 9. REINSURANCE:
 
   
     The ceding of insurance does not discharge the primary liability of CAC.
CAC places reinsurance with other carriers only after careful review of the
nature of the contract and a thorough assessment of the reinsurers' credit
quality and claim settlement performance. Further, for carriers that are not
authorized reinsurers in its states of domicile, CAC receives collateral,
primarily in the form of bank letters of credit. Such collateral totaled
approximately $14 million and $11 million at December 31, 1998 and 1997,
respectively.

NOTE 11. LEGAL:
 
   
     CAC is party to litigation arising in the ordinary course of business. The
outcome of this litigation will not, in the opinion of management, materially
affect the results of operations or equity of CAC.
    
 
NOTE 12. RESTRUCTURING
 
   
     CNA Financial finalized and approved a restructuring plan (the "Plan") in
August 1998. In conjunction with the Plan, the Group Operations of CAC incurred
$39 million in restructuring and other related charges, of which, approximately
$29 million related to costs incurred to exit the Employer Health and Affinity
lines of business. Such costs represent CAC's estimate of losses in connection
with fulfilling the remaining obligation under contracts related to these lines
of business. Earned premiums for these lines of business approximated $400
million in 1998. The 1998 charges also included employee severance and
outplacement costs of approximately $7 million related to the planned net
reduction in workforce of approximately 400 employees. Charges for lease
termination costs and fixed asset write downs totaled $3 million.
    
 
   
     The Life Operations of CAC incurred $7 million in restructuring and other
related charges. Charges related primarily to the closing of leased facilities
were $2 million, and employee severance and outplacement costs related to
planned net reduction of 30 employees in the current workforce and benefit costs
associated with those reductions were $1 million. In addition, there were
charges of $1 million related to the write down of certain assets and $2.5
million related to the exiting of certain businesses.
    
 
     The following table sets forth the major categories of restructuring and
other related charges that were initially accrued and recorded upon the
finalization and approval of the Plan and the activity in the accrual for such
costs during 1998.

other entities that purchase insurance as a group. Life Operations provides
financial protection to individuals through a full product line of term life
insurance, universal life insurance, long term care insurance, annuities and
provides retirement service products to institutional markets. Corporate results
consist of operating and investing activities not attributable to operating
segments.
 
   
     The accounting policies of the segments are the same as those described in
the summary of significant accounting polices. CAC manages its assets on a legal
entity basis while segment operations are conducted across legal entities, as
such assets are not readily identifiable by individual segment. In addition,
distinct investment portfolios are not maintained for each segment, and
accordingly, allocation of assets to each segment is not performed. Investment
income and realized investment gains/losses are allocated based on each
segment's equity, as adjusted.
    
 
     Depreciation and capital expenditures are not material to segments' income
and cash flow.
 
     All significant intercompany income and expense as well as intercompany
dividends have been eliminated.
 
     Income taxes have been allocated on the basis of taxable income of the
respective segments.
 
   
     Approximately 98% of CAC's premiums are derived from the United States.
Premiums from any individual foreign country are not significant.
    
 
     Group segment revenues include $2.0 billion, $2.1 billion and $2.1 billion
in 1998, 1997 and 1996, respectively, under contracts covering U.S. government
employees and their dependents (FEHBP).

NOTE 14. NEW ACCOUNTING PRONOUNCEMENTS
    
 
   
ACCOUNTING BY INSURANCE AND OTHER ENTERPRISES FOR INSURANCE-RELATED ASSESSMENTS
    
 
   
     In December 1997, the American Institute of Certified Public Accountants'
Accounting Standards Executive Committee issued Statement of Position (SOP)
97-3, "Accounting by Insurance and Other Enterprises for Insurance-Related
Assessments." SOP 97-3 requires that entities recognize liabilities for
insurance-related assessments when all of the following criteria have been met:
an assessment has been imposed or it is probable that an assessment will be
imposed; the event obligating an entity to pay an imposed or probable assessment
has occurred on or before the date of the financial statements; and the amount
of the assessment can be reasonably estimated. This SOP is effective for
financial statements for fiscal years beginning after December 15, 1998. The
effects of this SOP will result in CAC recording a pre-tax charge in 1999
between $2 million and $5 million as a cumulative effect of a change in
accounting principle.
    
 
   
ACCOUNTING FOR THE COSTS OF COMPUTER SOFTWARE DEVELOPED OR OBTAINED FOR INTERNAL
USE
    
 
   
     In March 1998, the American Institute of Certified Public Accountants'
Accounting Standards Executive Committee issued SOP 98-1, "Accounting for the
Costs of Computer Software Developed or Obtained for Internal Use." For purposes
of this SOP, internal-use software is software acquired, internally developed or
modified solely to meet the entity's internal needs for which no substantive
plan exists or is

being developed to market the software externally during the software's
development or modification. Accounting treatment for costs associated with
software developed or obtained for internal use, as defined by this SOP, is
based upon a number of factors, including the point in time during the project
that costs are incurred as well as the types of costs incurred. This SOP is
effective for financial statements for fiscal years beginning after December 15,
1998 and will be adopted in the first quarter of 1999. CAC is currently
evaluating the effects of this SOP.
    
 
   
ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
    
 
   
     In June 1998, the Financial Accounting Standards Board issued SFAS 133,
"Accounting for Derivative Instruments and Hedging Activities." This statement
requires that entities recognize all derivatives as either assets or liabilities
in the statement of financial position and measure those instruments at fair
value. If certain conditions are met, a derivative may be specifically
designated as (a) a hedge of the exposure to changes in the fair value of a
recognized asset or liability or an unrecognized firm commitment, (b) a hedge of
the exposure to variable cash flows of a forecoasted transaction, or (c) a hedge
of the foreign currency exposure of a net investment in a foreign operation, an
unrecognized firm commitment, an available-for-sale security, or a
foreign-currency-denominated forecasted transaction. The accounting for changes
in the fair value of a derivative depends on the intended use of the derivative
and the resulting designation. This Statement is effective for all fiscal
quarters of fiscal years beginning after June 15, 1999. CAC is currently
evaluating the effects of this Statement on its accounting and reporting for
derivative securities and hedging activities.
    
 
   
REPORTING ON THE COSTS OF START-UP ACTIVITIES
    
 
   
     In April 1998, the American Institute of Certified Public Accountant's
Accounting Standards Executive Committee issued SOP 98-5, "Reporting on the
Costs of Start-Up Activities." This SOP requires costs of start-up activities
and organization costs, as defined, to be expensed as incurred. SOP 98-5 is
effective for financial statements in 1999. Initial application of this SOP
should be reported as a change in accounting principle, and will, accordingly,
involve a cumulative adjustment. CAC does not expect the adoption of the SOP to
have a significant impact on the operations or equity of CAC.
    
 
   
ACCOUNTING FOR INSURANCE AND REINSURANCE CONTRACTS THAT DO NOT TRANSFER
INSURANCE RISK
    
 
   
     In October 1998, the American Institute of Certified Public Accountant's
Accounting Standards Executive Committee issued SOP 98-7, "Accounting for
Insurance and Reinsurance Contracts That Do Not Transfer Insurance Risk." This
guidance excludes long-duration life and health insurance contracts from its
scope. This Statement is effective for financial statements in the year 2000,
with early adoption encouraged. CAC is currently evaluating the effects of this
SOP.

COUNTY OF COOK      )


Mary A. Ribikawskis, being duly sworn, deposes and says that she is Assistant
Secretary of Continental Assurance Company, an Illinois insurance company; that
the following is a true and correct copy of a resolution duly adopted by the
Board of Directors of Continental Assurance Company at a meeting duly called and
regularly held on the 2nd day of October, 1963, at which meeting a quorum was
present, and that said resolution has not been amended or repealed and is now in
full force and effect:

         WHEREAS, the Illinois Insurance Code was amended in June, 1963, to
         permit the establishment and maintenance of separate accounts and the
         allocation thereto of contributions paid to the Company pursuant to the
         agreements made in connection with a pension, retirement or
         profit-sharing plan and the allocation thereto of amounts paid to the
         Company under agreements reinsuring any such contracts of another
         insurer; and

         WHEREAS, competitive conditions in the marketing of pension, retirement
         or profit-sharing plans make it both desirable and to the best
         interests of the Company for the Company to be able to offer separate
         investment facilities for all or part of such pension, retirement or
         profit-sharing contributions or amounts paid to the Company under
         agreements reinsuring any such contracts of another insurer, without
         the customary guarantees by the Company of principal and interest, but
         with each participating contract in the separate account receiving
         actual investment results obtained on its share of the separate
         account;

         NOW, THEREFORE, BE IT RESOLVED: That the appropriate officers of the
         Company be and they are hereby authorized to establish and maintain one
         or more separate accounts to which may be allocated amounts paid to the
         Company under agreements made in connection with a pension, retirement
         or profit-sharing plan or under agreements reinsuring any such
         contracts of another insurer and in the event that more than one
         separate account is established said officers are authorized to set
         different investment policies for different separate accounts and are
         further authorized to make such reasonable rules and regulations as may
         be necessary or appropriate for the proper administration of such
         separate accounts in accordance with applicable law.

such purpose.

     This Agreement shall continue in force for one year from the date hereof

the members of the Committee of the Separate Account who are not parties to the
Agreement or interested persons of any such party, cast in person at a meeting
called for the purpose of voting on such approval.

Dear Contractholder:

The United States Supreme Court recently rendered a decision that could have a
significant impact on your pension or profit sharing plan.

In the case of ARIZONA GOVERNING COMMITTEE FOR TAX DEFERRED COMPENSATION PLANS
v. NORRIS, the Supreme Court ruled that Title VII of the Civil Rights Act of
1964 prohibits an employer from offering employees the option of receiving
retirement benefits in a form which results in unequal payments for men and
women. The Supreme Court also held that the employer cannot provide these
benefits even if it utilizes an insurance company which uses sex-based mortality
tables. Additionally, the Court held that benefits derived from contributions
collected after AUGUST 1, 1983, must be calculated without regard to the sex of
the employee.

These rulings, as they relate to the Civil Rights Act of 1964, affect employers
with fifteen or more employees. However, several individual states have adopted
their own Fair Employment Practices Act that apply to smaller groups of
employees. We suggest that you consult your attorney regarding the effect of
this decision upon your plan.

CNA's current pension and profit sharing contracts contain guaranteed annuity
rates based on sex-distinct mortality tables. Enclosed is a Rider to your
contract that provides you with the option to elect the use of unisex annuity
rates for all or any portion of an annuity purchased under your contract. If, in
the future, our current unisex rates are lower than the guaranteed rates, they
will, of course, be used for the purposes of quoting and purchasing annuities.

If you have any questions, please feel free to call or write.

Sincerely,



/s/ SEYMOUR ADAMS

                            GROUP CONTRACT AMENDMENT

     Group Variable Annuity Contract Number _________________________________ is
amended as follows:

     1.   Subsection (g) of Section 1.1, titled "Definitions", is amended to
          read as follows:

               "(g) SEPARATE ACCOUNT OR SEPARATE ACCOUNT (B)

               The assets of the Company in a segregated investment account,
               titled "Continental Assurance Company Separate Account (B)",
               established by the Company.

     2.   Section 2.2, titled "Definitions", is deleted.

     3.   Sections 1.4, 1.5, 1.6 and 1.7 (2) are amended to reduce the minimum
          initial monthly annuity payment from $25 to $20.

     4.   Section 2.5, titled "Investment of Separate Account", is deleted and
          the following substituted therefor:

               "2.5 THE SEPARATE ACCOUNT

               All assets of the Separate Account are owned by the Company and
               the Company shall not be, nor hold itself out to be, a trustee
               with respect to such assets. The assets of the Separate Account
               equal to the reserves and other contract liabilities with respect
               to the Separate Account shall not be charged with liabilities
               arising out of any other business the Company may conduct.

               The Participant's rights under the Contract are nonforfeitable.
               Each Participant is the sole owner of his Individual Account."

     5.   Section 2.6, titled "Value of Accumulation Units", is amended to read
          as follows:

               "2.6 VALUE OF ACCUMULATION UNITS

               The value of an accumulation unit on any valuation date is equal
               to the net asset value of the Separate Account divided by the
               number of accumulation units outstanding. The net asset value of
               the Separate Account is the market value of all securities and
               other assets, less liabilities of the Separate Account. Any
               income tax payable by the Company with respect to the assets of
               the Separate Account may be included with other liabilities in
               determining net asset value.

               Deductions will be made by the Company from the Separate Account
               for investment advisory fees and other charges and expenses under
               agreements between the Company and the Separate Account which are
               approved by the vote of a majority of the Participants in
               accordance with the Investment Company Act of 1940 as amended and
               which are described in current prospectuses for the Separate
               Account.

     Group _______________ Annuity Contract Number __________________________ is
amended as follows:

          The last paragraph of Section ________________________________________
          is deleted and the following substituted therefor:

          Participant and his spouse at the Effective Annuity Date on the basis
          of the mortality table used to determine the annuity payments.

          If a Plan adopted by the Contractholder and communicated to the
          Company provides for a qualified joint and survivor annuity as defined
          in the Employees' Retirement Income Security Act of 1974, the
          automatic annuity form under the Contract for each participant to whom
          such provision is applicable shall be an annuity for the life of the
          Participant with a survivor annuity for the life of his spouse which
          is not less than one-half, nor greater than, the amount of the annuity
          payable during the joint lives of the Participant and his Spouse and
          which is the actuarial equivalent of a single life annuity for the
          life of the participant."

     otherwise indicated by the context, and the singular number shall to the
     same extent include the plural.

1.3  DETERMINATION OF BENEFITS

     All benefits under this Contract shall be on a "money purchase" basis. The
     size of a Participant's Individual Account hereunder will depend on the
     amount of funds transferred to it, and the subsequent investment experience
     thereon, as hereinafter provided. The amount of benefit payable to a
     Participant at any time prior to retirement shall be determined solely by
     the value of the Participant's Individual Account at that time, as computed
     by the Company in the manner hereinafter provided.

1.4  RETIREMENT BENEFIT

     A Participant shall be entitled to have provide under this Contract, a
     monthly Variable Annuity on the Normal Annuity Form, commencing at his
     Effective Annuity Date, and in an amount purchasable by his Individual
     Account when applied to the proper single premium table contained in Part
     IV of this Contract. Provided, that the initial monthly payment must be at
     least $25.00 in amount; if this condition cannot be met on the Normal Form,
     nor under any annuity option which the Participant is willing to elect, the
     value of the Participant's Individual Account shall, at the option of the
     Participant, be paid in a lump sum, or be transferred to the Companion
     Contract for payment in accordance with its terms.

     The Company may indicate to each Participant from time to time, the initial
     monthly annuity on the Normal Form which could be provided at various ages
     of retirement by an accumulation to those ages at an assumed rate of
     investment return of the current value of the Participant's Individual
     Account. However, no Variable Annuity shall be guaranteed by the Company
     prior to the Effective Annuity Date of the Participant.

1.5  ANNUITY OPTIONS

     A Participant may select any annuity option under this Contract, and make
     changes therein, at any time, up to 30 days prior to the Effective Annuity
     Date. A Participant entitled to a Variable Annuity under this Contract may,
     subject to the following conditions, and with Company consent, elect any
     annuity option available under the Companion Contract, to be payable under
     this Contract on a variable basis in lieu of the Variable Annuity on the
     Normal Annuity Form. Election of the option shall be subject to the same
     requirements as election of that option under the Companion Contract. The
     amount of the annuity payable under such an option shall be determined by
     the Company from the amount of the Participant's annuity on the Normal
     Annuity Form, from tables actuarially consistent with those in Part IV, and
     available to the Employer on request. No such option may in any event be
     elected unless the first payment would be at least $25.00 in amount. Other
     conditions of payment applicable to each such option shall be set by the
     Company, and described in the annuity certificate.

     Annuity options under this Contract shall include:

     (1)  An annuity payable monthly during the life of the Participant, ceasing
          with the payment due as of the first day of the month of death;

     (2)  An annuity payable monthly to the Participant during his life, and on
          his death continued for life in the same amount to a contingent
          annuitant designated by the Participant at retirement;

     (3)  An annuity payable monthly during the life of the Participant with the
          guarantee that if, at the death of the Participant the number of
          payments made are less than the number set in the election (60, 180 or
          240), the remaining payments shall be discounted at the reserve rate
          and paid to the Beneficiary in a single sum.

     Notwithstanding the foregoing and anything else in this Contract, no
     annuity benefit may be paid under the Contract on such a basis that
     installments certain would be payable for a period greater than twenty
     years.

1.6  DEATH OF PARTICIPANT

     If the death of Participant occurs prior to his Effective Annuity Date, the
     Company, upon receipt of reasonable evidence of his death, will pay to his
     Beneficiary a single sum equal to the amount of the Participant's
     Individual Account determined as of the Valuation Date next preceding the
     date such evidence is received at its Home Office.

     By written instructions for settlement, a Participant may elect to have the
     whole or any part of the death benefit paid to a Beneficiary under any of
     the retirement options in Section 1.5 of this Contract. Each monthly
     payment to be determined on the basis of the rates shown in the Tables in
     Part IV for the option elected; provided, however, that if such amount
     would provide less than $25.00 per month, it shall nevertheless be paid in
     a single sum. If no such election is in force at the time of the
     Participant's death, such election may be made by, but only for the benefit
     of, such Beneficiary.

                                      -3-

1.7  OTHER TERMINATION

     On a termination of participation hereunder by a Participant other than
     through death or retirement, the Participant may elect any one of the
     following options, subject to the conditions given.

     (1)  CASH SETTLEMENT

          The value of the Participant's Individual Account on the Valuation
          Date next preceding the date written election of such option is
          received in the Home Office of the Company (coinciding with, if
          received on a Valuation Date) will be paid to him by the Company in a
          single sum.

     (2)  ACCUMULATION

          The Participant may allow his Individual Account to remain under the
          Contract, without further contributions, and with continued full
          participation in the investment experience hereof, for later payment
          in a lump sum on written election thereto, or (if at least $25.900 a
          month initially) as an annuity. Provided, that this option shall be
          available only if at the effective date of termination, the value of
          the Individual Account is not less than $2,000.00.

     (3)  TRANSFER

          The Participant may have the value of his Individual Account
          transferred to the Companion Contract, for retention thereunder
          according to its terms; or, if the Participant shall have a new
          employer which has a contract of this same type in force with the
          Company, the transfer may be to such contract.

     In the event no election is received from a Participant on termination of
     participation, Option (2) shall be automatic, unless the value of the
     Individual Account is beneath the minimum, in which event the Company may
     proceed as though Option (1) had been elected. If the Company does not
     proceed on the basis of Option (1), Option (2) shall apply. The expression
     "termination of participation" shall include the non-receipt of minimum
     contributions by the Company with respect to a Participant for 24
     consecutive months.

1.8  COMMITTEE

     The general operation of Equity Fund (B) shall be subject to periodic
     review by a Committee, elected by the Participants hereunder, together with
     Participants under similar contracts with the Company. The terms and
     conditions of the Committee's supervision over Equity Fund (B) is set forth
     in a Management Agreement between the Company and Equity Fund (B).

                                    PART II

            OPERATION OF EQUITY FUND: PAYMENT OF VARIABLE ANNUITIES

     2.1  APPLICATION

          The Contractholder shall, on the written election by a Participant,
          made in proper form, direct the Company to place some or all of the
          contributions made for the Participants in Equity Fund (B) maintained
          by the Company, in lieu of being retained under the Companion
          Contract, subject to the provisions of that Contract and to the
          conditions of this Part. All assets deriving from a contribution
          placed under this Contract shall, from the next following Valuation
          Date, be subject to the special provisions of this Part II, as long as
          those assets remain in Equity Fund (B).

     2.2  DEFINITIONS

          The term "Equity Fund (B)" as used herein shall mean those assets of
          the Company which are allocated to a separate equity account by the
          Company, pursuant to this Contract, and to which the earnings and
          expenses, gains and losses, stemming from the investment thereof,
          shall be credited or charged without regard to the investment
          experience on assets of the Company not allocated to said separate
          account. Equity Fund (B) is a common fund, invested primarily in
          equities, and shall be available to the Contractholder and to such
          other non-profit organizations who may be holders of group pension
          contracts issued by the Company, but only with respect to annuities
          entitled to tax deferment under Section 403(b) of the Internal Revenue
          Code.

     2.3  TRANSFERS TO EQUITY FUND (B)

          Current contributions or portions thereof which are designated by the
          Contractholder for investment in Equity Fund (B) shall be credited to
          the Equity Fund as of the Valuation Date next following date of
          receipt by the Company, unless a contribution is received on a
          Valuation Date, in which event it shall be credited to the Equity
          Fund as of that date. Provided, that the Company shall not be required
          to make such transfer unless the Contractholder shall have furnished
          the Company with a detailed list of such contributions showing
          allocations among the Participants to which such contributions relate.
          The minimum single contribution allocable to a Participant shall be
          $10.00.

     2.4  ACCUMULATION UNITS

          The assets of Equity Fund (B) shall, for accounting purposes, be
          apportioned among equal units which shall be known as Accumulation
          Units. The interest of this Contract in Equity Fund (B), and in the
          net earnings, and gains and losses,

                                      -5-
<PAGE>   16
     realized and unrealized, in Equity Fund (B) shall be proportionate to the
     number of Accumulation Units credited hereto, compared to the total number
     of Accumulation Units then outstanding. (The monetary value, or fair value,
     of an Accumulation Unit was set arbitrarily at $1.00000 on June 30, 1966.
     The fair value at any other Valuation Date is determined from the fair
     value of the Equity Fund and the number of Units outstanding as hereinafter
     described.)

     The Company shall credit to this Contract on account of each allocation
     made hereunder to the Equity Fund, that number of Accumulation Units which
     a percentage of such allocation will purchase, at the fair value of an
     Accumulation Unit on the Valuation Date of allocation. The percentage shall
     be 94%. The 6% balance of such allocation shall not be placed in the Equity
     Fund, but shall be held by the Company as a part of its regular
     non-participating assets, for present and future expenses hereto, and for
     surplus and contingencies.

     The value of each Individual Account under this Contract shall be measured
     by the number of Accumulation Units held to the credit of that Individual
     Account. The Company shall maintain records of the Accumulation Units
     credited to each Individual Account, with the totals for all Individual
     Accounts hereunder being equal to the interest of this Contract in Equity
     Fund (B). (For this purpose, Accumulation Units previously transferred to
     the Variable Annuity account, to be defined, shall be excluded.)

2.5  INVESTMENT OF EQUITY FUND

     The Company shall, from time to time, solely at its own discretion, and
     without regard to requirements for investment which may pertain to the
     assets of the Company not allocated to said separate account, invest and
     re-invest the commingled assets of Equity Fund (B) in common stock, other
     equities, and (temporarily) in other securities; provided, however, that
     investments in common stock shall be stock (a) which is listed or admitted
     to trading on a securities exchange located in the United States or Canada,
     or (b) which is publicly held and traded in the "over-the-counter" market
     and as to which market quotations are readily available. Pending
     anticipated distributions, or forthcoming security purchases, the Company
     may retain in cash, without liability for interest, such portion of the
     principal of Equity Fund (B) as is reasonable under the circumstances.

     The Company shall be strictly accountable for all sums held in cash with
     respect to Equity Fund (B), but shall make no guarantee of the value from
     time to time of other assets of Equity Fund (B), or the investment results
     thereof, or the income thereon. All assets of Equity Fund (B) shall be
     owned by the Company pursuant to this and similar contracts and the Company
     shall not be, or hold itself out to be, a trustee with respect to such
     assets.

     All dividends, interest and other investment income received by the Company
     on assets of Equity Fund (B) shall be immediately credited to Equity Fund
     (B), provided that the Company shall be entitled to deduct from such income
     as of each Valuation Date which falls in a seven day Valuation Period, an
     amount equal to .0095825% of the total fair value of Equity Fund (B) on
     that date, as defined in the Section following, with such deductions being
     credited by the Company to its regular non-participating assets, for
     investment expenses and surplus. Deductions for Valuation Periods other
     than seven days shall be in proportion.

                                      -6-
<PAGE>   17

2.6  VALUE OF ACCUMULATION UNITS

     The fair value of Equity Fund (B) as of any given Valuation Date, before
     deposits of new contributions, or withdrawals for benefits then payable,
     shall be determined by the Company in the following manner:

     (a)  Securities held under Equity Fund (B) if listed on a national
          exchange, shall be valued according to the sales price of the last
          transaction on the Valuation Date. If no sale of such a security
          occurred on the Valuation Date, the value thereof shall be deemed
          equal to the closing bid on the Valuation Date. Securities not listed
          on a national exchange, but for which over-the-counter quotations are
          available, shall be valued at the mean of the closing bid and asked
          prices at the Valuation Date. Other securities for which sales prices
          or quoted prices are not available, or are no longer available, and
          all other investments and property shall be valued at prices
          considered by the Committee, in its best judgment, to represent the
          fair value thereof on the Valuation Date.

          For the purposes hereof, sales prices and bid and asked prices
          reported in newspapers of general circulation or in standard financial
          periodicals shall be used.

     (b)  Changes in holdings of portfolio securities effective on a date of a
          valuation shall be reflected in that valuation.

     (c)  Expenses, including any investment advisory fees, shall be included to
          date of valuation, and this shall include all accrued but unpaid
          charges and expenses.

     (d)  Dividends receivable shall be included to date of valuation if the
          underlying security is being traded ex-dividend on that date.

     (e)  Interest income and other similar income shall be computed to date of
          valuation, including accrued interest where a purchaser on that date
          would be required to pay accrued interest as a part of the purchase
          price.

     To the aggregate net value so determined, shall be added any uninvested
     cash balances, and there shall be subtracted any other liabilities, due or
     accrued. The net amount remaining shall be defined as the fair value of
     Equity Fund (B) on the Valuation Date. The fair value shall be computed to
     the nearest cent, and shall be redetermined on each successive Valuation
     Date in the same manner.

     When the fair value of Equity Fund (B) has been determined on a Valuation
     Date, the monetary value of an Accumulation Unit on that date shall then be
     found by dividing the fair value by the number of Accumulation Units
     outstanding on that date (prior to any new deposits or withdrawals) with
     respect to all contracts providing for investment in Equity Fund (B),
     including the Variable Annuity account. The monetary value of an
     Accumulation Unit shall be computed to the nearest one-thousandth of a
     cent.

                                      -7-
<PAGE>   18

2.7  NUMBER OF ACCUMULATION UNITS

     Except for a revaluation by the Company of the total number and value of
     all Accumulation Units in Equity Fund (B), the number of Accumulation Units
     credited to this Contract shall be increased only through allocation of an
     additional deposit to Equity Fund (B) on a Valuation Date, after the fair
     value of an Accumulation Unit has been determined for that date. Crediting
     of investment income or realized capital gains to Equity Fund (B) shall not
     change the number of Accumulation Units credited to this Contract (or to
     any other participating contract). Similarly, the number of Accumulation
     Units hereto shall be decreased only through liquidation of Accumulation
     Units on a Valuation Date for payment of benefits, or for the transfer of
     assets to the Group Annuity Fund under the Companion Contract.

2.8  TRANSFERS TO AND FROM COMPANION CONTRACT

     The Contractholder may, through written direction received by the Company
     at least ten days before the Valuation Date, have any portion of the assets
     of this Contract in Equity Fund (B) transferred to the Group Annuity Fund
     under the Companion Contract, provided that assets credited to the Variable
     Annuity account shall not be transferable, and that such transfers shall be
     subject to the prior consent of the Company.

     Transfers of sums to this Contract from the Companion Contract may be made
     on termination of that Contract, and may be made otherwise prior to the
     Effective Annuity Date under special circumstances with the consent of the
     Company.

2.9  TERMINATION OF EQUITY PARTICIPATION

     The Contractholder may, as of any Valuation Date, through written notice
     received by the Company at least ten days before such date, elect to
     terminate participation of this Contract in Equity Fund (B). Participation
     of the Contract in Equity Fund (B) shall terminate automatically on the
     Valuation Date next following termination of the Companion Contract.
     Participation of the Contract in Equity Fund (B) shall be immediately
     terminated on any finding by the District Director of the Internal Revenue
     that the annuity benefits hereunder do not meet the requirements of Section
     403(b) of the Internal Revenue Code. On termination, each Participant shall
     have the same options with respect to his Individual Account as are
     provided in Section 1.7 of Part I on termination of participation at the
     election of the Participant, except that the "accumulation" option shall
     not be available if termination was due to tax disqualification.

2.10 VARIABLE ANNUITIES

     Variable Annuities may be provided eligible Participants from the interest
     of this Contract in Equity Fund (B), subject to the other provisions of
     this Contract. Accumulation Units held as reserves for such Variable
     Annuities shall be separated by the Company from those held for future
     benefits of actively employed Participants,

                                      -8-
<PAGE>   19
     and credited to a Variable Annuity account. (This account shall also be
     credited with reserves for Variable Annuities provided under all other
     similar contracts issued by the Company, with all such reserves held in
     common.) The Company shall guarantee the mortality and future expense
     factors of Variable Annuities hereunder, but the investment element shall
     be directly related to the fair value from time to time of the Accumulation
     Units in the Variable Annuity account.

2.11 VARIABLE UNITS

     The amount of a Variable Annuity shall be measured in Annuity Units. The
     number of Annuity Units applicable to each such annuity shall be fixed at
     the Participant's Effective Annuity Date, and shall not change thereafter,
     unless the annuity shall be of such a form that the amount would change on
     the same circumstance if the annuity were a Fixed Annuity.

     The monetary value from time to time of an Annuity Unit shall depend on the
     current value of an Accumulation Unit, after an adjustment to reflect the
     annuity reserve interest rate. (The monetary value of an Annuity Unit was
     defined arbitrarily at $1.00000 on July 1, 1966, and thereafter was
     revalued on each first day of the month through May 1, 1968 based on the
     net change in the value of an Accumulation Unit during the preceding month,
     adjusted for the 3-1/2% per annum assumed earnings rate. Effective with the
     Valuation Period commencing June 1, 1968, the Annuity Unit was redefined as
     below, with the value during this Valuation Period being determined from
     the value May 1, 1968 and the change in the value of the Accumulation Unit
     in the period April 30 -- May 24, 1968.)

     A single monetary value shall prevail for the Annuity Unit throughout each
     Valuation Period. The monetary value of an Annuity Unit for each Valuation
     Period shall be determined from the value during the preceding Valuation
     Period by multiplying that value by the factor below:

         (Net investment factor for second preceding valuation period)
        ---------------------------------------------------------------
        (Compound interest factor for that period, at 3-1/2% per annum)

     The net investment factor for any Valuation Period shall be defined as the
     ratio of the monetary value of an Accumulation Unit on the Valuation Date
     falling in that period, to the monetary value of an Accumulation Unit on
     the Valuation Date falling in the next preceding Valuation Period.

2.12 PURCHASE OF VARIABLE ANNUITIES

     As of the Valuation Date immediately prior to a Participant's Effective
     Annuity Date (or coincident with, if also a Valuation Date) the number of
     Accumulation Units in a Participant's Individual Account shall be withdrawn
     by the Company from the account representing the regular interest of the
     Contract in Equity Fund (B) and credited by the Company to the Variable
     Annuity Account. (To this shall be added the net value of any current
     contribution received from the Participant, but not credited to the Equity
     Fund.) A Participant's initial annuity payment shall then be determined by
     dividing the value of his Individual Account as determined on the second
     preceding Valuation Date before the Effective Annuity Date by the
     appropriate single premium contained in Part IV of this Contract. The
     Participant's Variable Annuity shall then be translated into a permanent,
     fixed number of Annuity Units by dividing the initial

                                      -9-
<PAGE>   20
     annuity payment in dollars by the monetary value of an Annuity Unit during
     the Valuation Period in which the Effective Annuity Date falls, with the
     result computed to the nearest one hundredth of a unit.

2.13 PAYMENT OF VARIABLE ANNUITIES

     Each Variable Annuity shall be paid to the Participant by the Company on
     the continuously varying basis previously defined. Prior to the due date of
     each Variable Annuity payment, the Company shall determine the monetary
     amount to be then payable by multiplying the number of Annuity Units
     provided by the Variable Annuity, by the monetary value of an Annuity Unit
     during the Valuation Period in which the due date falls, and taking the
     product to the nearest cent.

     The Company shall guarantee the continued payment in full of the Annuity
     Units on each Variable Annuity under this Contract, for the payment period
     of the form of annuity involved. Not less frequently than once annually,
     the Company shall make a valuation of all Variable Annuities in course of
     payment hereunder. Any sum in excess of required reserves for future
     benefits and anticipated expenses may be removed by the Company from Equity
     Fund (B) and added to its non-participating surplus account. Any reserve
     deficiency shall be met by the Company through a transfer of the required
     sum from its general non-participating surplus to Equity Fund (B) for
     crediting to the Variable Annuity account of this Contract.

2.14 SINGLE SUM SETTLEMENTS UNDER VARIABLE ANNUITIES

     In the event that remaining guaranteed payments become payable in a single
     sum to a Beneficiary, the amount of the payment shall be found by first
     obtaining the single sum in terms of Annuity Units, by multiplying the
     amount of the annuity in Annuity Units, and the present value factor at
     3-1/2% per annum compound interest. The monetary amount of the settlement
     will then equal the amount in Annuity Unit times the monetary value of an
     Annuity Unit at the effective date of settlement.

2.15 TERMINATION OF MANAGEMENT AGREEMENT

     In the event that the Committee, pursuant to the provisions of the
     Management Agreement between the Company and Equity Fund (B), shall
     terminate the Management Agreement, the Company shall proceed as follows
     with respect to the interest of the Contractholder and Participants in
     Equity Fund (B). All assets of Equity Fund (B) shall be immediately
     liquidated by the Company. The values of the Individual Accounts of all
     Participants who have not retired, shall be paid to those Participants by
     the Company as soon as practicable thereafter. Provided that each such
     Participant shall have the option of requesting that his share in the
     proceeds be transferred to the Companion Contract (if being continued) or
     to a regular non-participating department of the Company, for application
     to provide a deferred fixed annuity. The equitable shares in the proceeds
     of the Variable Annuity account shall be transferred by the Company to its
     regular non-participating department, and applied to provide fixed
     annuities to all retired Participants, in the same form, and on the same
     actuarial reserve bases as the Variable Annuities then in effect for the
     retired Participants. To the extent permitted by the proceeds from
     liquidation, the amount of each fixed annuity shall be the same as the last
     variable payment received under it.

                                    PART III

                               GENERAL PROVISIONS


3.1  ASSIGNMENT OF BENEFITS

     The interest of either a Participant or a Beneficiary under this Contract
     may not be sold, assigned, discounted or pledged as collateral for a loan
     or as security for the performance of an obligation, or for any other
     purpose, to any person other than the Company. Such interest, benefits and
     payments shall not be subject to any legal process to levy upon or attach
     the same, for payment of any claim against any Participant or Beneficiary.

3.2  CERTIFICATES

     When a Participant becomes entitled to an annuity benefit hereunder, the
     Company will issue an individual certificate to the annuitant describing
     the benefit.

3.3  ENTIRE CONTRACT

     The Contract and the Application, a copy of which is attached hereto, shall
     constitute the entire contract between the parties with respect to Equity
     Fund (B) and Variable Annuities.

3.4  FACILITY OF PAYMENT

     In the event that the Company deems the recipient of any payment hereunder
     to be legally incompetent, the Company shall have the right, in settlement
     of full liability thereto, to make the payment to such guardian, relative
     or other person who in the Company's opinion is contributing toward the
     support of the recipient.

     If a benefit is due on the death of a Participant, and no Beneficiary shall
     be named, or if the named Beneficiary shall not survive, the Company may,
     in full discharge of its liability, pay such benefit to any one or more of
     surviving spouse, parents, children, brother or sister.

3.5  EXCLUSION OF ADDITIONAL UNITS

     The Contractholder may, with the permission of the Company, include
     additional divisions, subsidiaries or other units under the control of the
     Contractholder, effective from any Anniversary Date.

<PAGE>   22
3.6  INFORMATION

     The Contractholder shall furnish the Company in writing at its Home Office
     with the names and other data reasonably necessary for the administration
     of this Contract, and shall notify the Company of all changes affecting
     this Contract promptly in writing at its Home Office. The Company shall
     have no liability for the payment of any benefit with respect to which the
     Contractholder or a Participant has refused to furnish required information
     or to submit necessary forms.

3.7  MISSTATEMENTS AND ERRORS

     If the date of birth or other information affecting the amount of a benefit
     or premium is determined by the Company to have been misstated, adjustments
     shall be made by the Company so as to conform with the true facts. If the
     amount of an annuity has been understated, a single sum shall be paid to
     the annuitant equal to the total in dollars of the errors in annuity
     payments made; if an overstatement, annuity payments shall be suspended
     until the overpayment in dollars is recovered.

3.8  MODIFICATION OR AMENDMENT

     This Contract cannot be modified or amended, nor its provisions waived or
     extended, in any respect, except with the written consent of the Company,
     in compliance with the laws of the state in which this Contract is issued.
     Such written consent must be signed by the President; a Vice-President, the
     Secretary or an Assistant Secretary of the Company whose authority will not
     be delegated.

     With the written consent of the Company, the Contractholder may, at any
     time and from time to time, amend this Contract in any respect, without the
     consent of any Participant; provided that no such amendment shall deprive
     the Participant of any right to benefits accrued under this Contract as of
     the effective date of such amendment.

3.9  NON-PARTICIPATING

     This Contract is non-participating, and shall be held with the other
     non-participating business of the Company.

3.10 PROOF OF AGE

     Notwithstanding the other provisions of this Contract, no annuity shall be
     paid unless and until proof of date of birth for the Participant has been
     submitted to and accepted by the Company.

3.11 RESERVES

     Reserves for Variable Annuities shall be computed on the Group Annuity
     Table for 1951 adjusted and projected, with interest at three and one-half
     per cent per annum.

                                      -12-

3.12 REVISION OF RATES

     The Company reserves the right to revise the annuity premiums herein or to
     change the deduction made from new allocations, subject to the following
     provisions. No revisions shall be made with respect to annuities in course
     of payment, nor shall any revision be made with respect to the deduction
     from allocation of Participants who are covered during the first five
     contract years. No revision in premium rates shall be made with respect to
     Participants born prior to January 1, 1907. Further, the Company guarantees
     that the rates applicable to other Participants covered in the first five
     contract years shall not exceed the rates resulting from the following
     modifications of those of Table 4.1:

                      [CNA INSURANCE COMPANIES LETTERHEAD]


August 31, 1983



Dear Contractholder:

The United States Supreme Court recently rendered a decision that could have a
significant impact on your pension or profit sharing plan.

In the case of Arizona Governing Committee for Tax Deferred Compensation Plans
v. Norris, the Supreme Court ruled that Title VII of the Civil Rights Act of
1964 prohibits an employer from offering employees the option of receiving
retirement benefits in a form which results in unequal payments for men and
women. The Supreme Court also held that the employer cannot provide these
benefits even if it utilizes an insurance company which uses sex-based mortality
tables. Additionally, the Court held that benefits derived from contributions
collected after August 1, 1983, must be calculated without regard to the sex of
the employee.

These rulings, as they relate to the Civil Rights Act of 1964, affect employers
with fifteen or more employees. However, several individual states have adopted
their own Fair Employment Practices Act that apply to smaller groups of
employees. We suggest that you consult your attorney regarding the effect of
this decision upon your plan.

CNA's current pension and profit sharing contracts contain guaranteed annuity
rates based on sex-distinct mortality tables. Enclosed is a Rider to your
contract that provides you with the option to elect the use of unisex annuity
rates for all or any portion of an annuity purchased under your contract. If, in
the future, our current unisex rates are lower than the guaranteed rates, they
will, of course, be used for the purposes of quoting and purchasing annuities.

If you have any questions, please feel free to call or write.

Sincerely,

/s/ SEYMOUR ADAMS

2.01 CONTRIBUTIONS; SALES CHARGE

     The Company will receive contributions from the Contractholder on behalf of
     each Participant under the Contract. The amount allocated to a
     Participant's Variable Accumulation Account from each contribution will be
     equal to the contribution less the sales charge stated in the following
     table. The sales charge for each Participant will be determined on the
     basis of total contributions to date on his behalf, including the current
     contributions, under both the Contract and the Companion Contract.

<TABLE>
<CAPTION>
       Total Contributions                 Sales Charge
       -------------------                 ------------   
<S>                                        <C>
        First $10,000                           5 %
        Over $10,000 up to $20,000              4 %
        Over $20,000                         2 1/2%
</TABLE>

     The amount of each contribution on behalf of a Participant to his Variable
     Accumulation Account must be at least $10.00

2.02 ADMINISTRATION CHARGE

     An annual administration charge in an amount determined by the Company will
     be deducted from each Variable Accumulation Account at the end of each
     Calendar Year. The deduction will be in the form of accumulation units and
     will be based on the actual cost of administration of this class of
     contracts during the previous Calendar Year. It will be calculated by
     dividing the amount of the administration charge by the accumulation unit
     value on the valuation date on which the charge is made. The administration
     charge for any Participant who is covered under the Contract for only a
     portion of a Calendar Year will be prorated on a monthly basis. If no
     contributions are received on behalf of a Participant during a calendar
     year the deduction from the Participant's Variable Accumulation Account for
     that year will be 50% of the administration charge which would otherwise be
     made.

2.03 TRANSFERS TO AND FROM THE COMPANION CONTRACT

     The Participant, through written direction to the Company, may have any
     portion of his Variable Accumulation Account under the Contract transferred
     to the Companion Contract for application under its terms, provided that
     (a) Variable Accumulation Account values which have been applied to provide
     annuities under the Contract are not transferable, and (b) a charge of
     $10.00 will be made on the second and each succeeding transfer made in each
     Calendar Year. The Participant may, through written direction to the
     Company and subject to the conditions of the Companion Contract, transfer
     monies to the Contract from the Companion Contract.

2.04 WITHDRAWALS

     The Participant, through written direction to the Company, may withdraw any
     portion of his Variable Accumulation Account, subject to the restriction
     that Variable Accumulation Account values which have been used to provide
     annuities under the Contract cannot be withdrawn.

2.05 TERMINATION OPTIONS

     A Participant may elect any one of the following options on termination of
     Participation prior to his Effective Annuity Date other than through death
     or retirement.

                (1)   CASH SETTLEMENT

                      The Company will pay the Participant the then dollar value
                      of his Variable Accumulation Account in a single sum. The
                      dollar redemption value will be determined on the
                      Valuation Date following receipt of notice of termination
                      if no other option is elected.

                (2)   ACCUMULATION

                      The Participant may allow his Variable Accumulation
                      Account to remain under the Contract, without further
                      contributions, and with continued full participation in
                      the investment experience of the Contract, for later
                      payment under Termination Option 1, or, on written
                      election, as an annuity subject to the provisions of the
                      annuity options in Section 4.02. The Variable Accumulation
                      Account can remain under this option up to the 75th
                      birthday of the Participant when either the Cash
                      Settlement option or an annuity option must be elected.

                (3)   TRANSFER

                      The Participant may have the value of his Variable
                      Accumulation Account transferred to the Companion Contract
                      for retention according to its terms.

                (4)   CHANGE OF EMPLOYER

                      If the Participant terminates his employment and his
                      subsequent employer has a contract of this type in force
                      with the Company, a transfer may be made to that contract.

                      In the event no election is received from a Participant on
                      termination of Participation, Option (2) will be
                      automatic.

2.06 DEATH BENEFIT

     If the death of a Participant occurs prior to his Effective Annuity Date,
     the Company will pay to his Beneficiary a death benefit equal to the amount
     of the Participant's Variable Accumulation Account.

     By written notice to the Home Office of the Company, a Participant may
     elect to have the whole or any part of the death benefit paid to a
     Beneficiary under any of the annuity options in Section 4.02 of the
     Contract. If no such election is in force at the death of the Participant,
     the Beneficiary may elect to leave the Fixed Accumulation Account under the
     Accumulation provision described in Section 2.05 for any period of time up
     to what would have been the Participant's 75th birthday, or to receive the
     whole or any part of the death benefit in a single sum or under any of the
     annuity options in Section 4.02 of the Contract.

                       PART III - ACCUMULATION UNIT VALUES

3.01 OWNERSHIP

     The Participant's rights under the Contract are non-forfeitable. Each
     Participant is the sole owner of his Variable Accumulation Account.

3.02 ACCUMULATION UNITS

     The assets of Separate Account (B) will be apportioned among equal units
     called accumulation units. The number of accumulation units credited to a
     Participant's Variable Accumulation Account is determined by dividing the
     current contribution (less the sales charge) applicable to that Participant
     by the dollar value of an accumulation unit as of the date the
     contribution is applied.

3.03 VALUE OF ACCUMULATION UNITS

     The value of an accumulation unit was established at $1.00000 on June 30,
     1966. The value of an accumulation unit on any valuation date is equal to
     the net asset value of the Separate Account divided by the number of
     accumulation units outstanding.
<PAGE>   12

     The net asset value of the Separate Account is the market value of all
     securities and other assets less liabilities. Market value is determined by
     appraising (1) portfolio securities which are traded on a national
     securities exchange at the last sale price, or, if there is no sale price,
     at the closing bid; (2) other securities not so traded, for which
     over-the-counter market quotations are available, at the bid price; (3) all
     other securities and other assets at a fair value determined in the best
     judgment of the Separate Account Committee. Any income tax payable by the
     Company with respect to the assets of the Separate Account may be included
     with other liabilities in determining net asset value.

     A deduction will be made by the Company for investment advisory services at
     an annual rate of .5% of the average value of the Separate Account.

                       PART IV - ANNUITY BENEFIT PAYMENTS

4.01 ANNUITY BENEFIT

     Each Participant under the Contract is entitled to receive a Variable
     Annuity commencing on his Effective Annuity Date. The Participant may also
     elect to have any or all of his Variable Accumulation Account transferred
     to the Companion Contract for the purchase of an annuity according to its
     terms.

4.02 ANNUITY OPTIONS

     A Participant may elect any annuity option under the Contract at any time
     up to 30 days prior to his Effective Annuity Date. If no option is elected
     the Automatic Annuity Form will be Option 1 with 120 monthly payments
     guaranteed.

     OPTION 1

         Life Annuity with 60 or 120 Monthly Payments Guaranteed - Monthly
         payments during the lifetime of the Participant with a guarantee that,
         if at the death of the Participant payments have been made for less
         than 60 or 120 months as selected, annuity payments may, at the option
         of the Beneficiary, be discounted at the Assumed Investment Rate and
         paid as one sum or be continued to the Beneficiary during the remainder
         of the selected period. If the Beneficiary dies while receiving annuity
         payments, the remainder of the guaranteed payments will be discounted
         at the Assumed Investment Rate for payment as one sum to the estate of
         the Beneficiary.

    OPTION 2

         Life Annuity - Monthly payments during the lifetime of the Participant,
         ceasing with the last payment due prior to the death of the
         Participant.

    OPTION 3

         Joint and Survivor Annuity - Monthly payments during the lifetime of
         the Participant, and on his death continued for life in the same number
         of annuity units to a contingent annuitant designated by the
         Participant prior to his Effective Annuity Date.

     Other options are available with the consent of the Company and will be
     furnished on request.

     No option may be elected unless the initial payment would be at least
     $25.00. If this condition cannot be met through use of the Automatic
     Annuity form or under any annuity option which the Participant is willing
     to elect, the value of the Participant's Variable Accumulation Account will
     be paid in one sum.

     No option may be elected which has a certain period longer than the life
     expectancy of the Participant, (or, in the case of a Joint and Survivor
     Annuity, the Participant and his spouse,) at the Effective Annuity Date on
     the basis of the morality table used to determine the annuity payments.

4.03 DETERMINATION OF INITIAL PAYMENT

     The tables contained in Part VII of the Contract are used to determine the
     initial monthly annuity payment. They show the dollar amount of the initial
     monthly payment which can be purchased by each $1,000 applied.

     A Participant's initial annuity payment will be determined as the product
     of (a) the Initial Monthly Income Provided by Application of $1,000 shown
     in Part VII and (b) the value of his Variable Accumulation Account
     determined as of the 15th day of the calendar month preceding his Effective
     Annuity Date less any applicable premium taxes not deducted under the
     provisions of Section 6.08.
<PAGE>   13


     The monthly incomes shown in the tables of Part VII are based on the Group
     Annuity Table for 1951 adjusted and projected with interest at the Assumed
     Investment Rate of 3 1/2%. The amount of initial monthly payment depends
     on the sex and adjusted age of the Participant. The adjusted age is
     determined from the actual age on the birthday nearest to the Effective
     Annuity Date in the following manner:

<TABLE>
<CAPTION>
               Year of Retirement                Adjusted Age
               ------------------                ------------
                  <S>                          <C>  
                  1971 - 1975                     Actual Age
                  1976 - 1985                  Actual Age minus 1
                  1986-1995                    Actual Age minus 2
                  1996 - and later             Actual Age minus 3
</TABLE>

     The Assumed Investment Rate is incorporated into the annuity tables. This
     rate will be 3 1/2%, unless an optional rate is elected by the Participant
     at least 30 days prior to the date annuity payments are to commence. The
     optional rates are 3%, 4%, 4 1/2%, and 5%.

     The Company guarantees that, if at the Effective Annuity Date, the
     mortality basis then used in determining annuity rates for this class of
     contracts would produce more favorable results, the Company will use the
     more favorable basis with the chosen Assumed Investments Rate in
     calculating the Initial Payment.

4.04 SUBSEQUENT PAYMENTS

     Variable Annuity Payments after the first are measured in Annuity Units.
     The number of Annuity Units owned by each Participant is determined by
     dividing his Initial Annuity Payment by the Annuity Unit Value at the
     Effective Annuity Date. The amount of each subsequent annuity payment is
     the product of (1) the number of Annuity Units owned by the Participant and
     (2) the Annuity Unit Value for the valuation period in which the payment is
     due, rounded to the nearest cent.

     The Annuity Unit Value was established at $1.00 on July 1, 1966. It is
     redetermined on the first day of each month by applying the value of an
     Annuity Unit as of the first day of the preceding month to the ratio of (a)
     to (b), where (a) is the ratio of the monetary value of an accumulation
     unit on the fifteenth day of the preceding month to the value of an
     accumulation unit on the fifteenth day of the second preceding month, and
     (b) equals (1 + i) 1/12, with "i" equal to the Assumed Investment Rate.

                   PART V - THE CONTRACT AND SEPARATE ACCOUNT

5.01 ENTIRE CONTRACT

     The Contract and the application of the Contractholder, a copy of which is
     attached to the Contract, constitute the entire contract between the
     parties.

5.02 INFORMATION

     The Contractholder will furnish to the Company in writing at its Home
     Office information reasonably necessary for the administration of the
     Contract, and will notify the Company promptly and in writing at its Home
     Office of all changes affecting the Contract.

5.03 AMENDMENTS

     The Contract may not be modified or amended, nor its provisions waived or
     extended in any respect, except with the written consent of the Company and
     in compliance with the laws of the State in which the Contract is issued.
     Written consent must be signed by the President, a Vice-President, the
     Secretary or an Assistant Secretary of the Company whose authority will not
     be delegated.

     With the written consent of the Company, the Contractholder may amend the
     Contract at any time without the consent of any Participant, provided that
     no amendment will deprive a Participant of any rights to benefits accrued
     under the Contract as of the effective date of the amendment. The Company
     may amend the Contract to conform to applicable Federal or State laws or
     regulations or to changes in the operation of the Separate Account which
     have been approved by vote of the Participants or by the Separate Account
     Committee.

     The Company reserves the right to revise the annuity tables in Part VII,
     the deduction from contributions in Section 2.01, the administration charge
     in Section 2.02 and the transfer charge in Section 2.03, subject to the
     following restrictions: (a) no revision will be made with respect to
     annuities in course of payment, and (b) the annuity purchase rates will be
     guaranteed for annuities elected during the initial 5 Contract Years. Any
     revisions will be made by giving notice to the Contractholder at least 90
     days before the date the change is to take effect.

<PAGE>   14

5.04 TERMINATION OF THE CONTRACT

     The Contractholder may, as of any Valuation Date, through written notice
     received by the Company at least 30 days before this date, elect to
     terminate the Contract. The Contract and participation in Separate Account
     (B) will terminate immediately upon any finding by the District Director of
     the Internal Revenue Service that the annuity benefits do not meet the
     requirements of Section 403(b) of the Internal Revenue code.

     If the Contract terminates, each Participant will have the same options
     with respect to his Variable Accumulation Account as are provided in
     Section 2.05, except that the "Accumulation" option will not be available
     if termination is due to tax disqualification.

5.05 EXPERIENCE RATING

     At the sole discretion of the Company a credit may be allocated to the
     Contract after comparing the costs incurred by the Contract with the sales
     and administration charges. This credit, if allocated, may be in the form
     of an increase in benefits or a reduction in the sales or administration
     charges. The credit may be applied at any time after the experience rating
     period. An experience rating period is any period of time not less than 12
     months.

5.06 THE SEPARATE ACCOUNT

     All assets of the Separate Account are owned by the Company and the Company
     shall not be, nor hold itself out to be, a trustee with respect to such
     assets. The assets of the Separate Account equal to the reserves and other
     contract liabilities with respect to the Separate Account may not be
     charged with liabilities arising out of the other business the Company may
     conduct.

5.07 TERMINATION OF SEPARATE ACCOUNT MANAGEMENT AGREEMENT

     In the event the Management Agreement for the Separate Account is
     terminated, the Company will liquidate all assets of the Separate Account.
     The values of the Variable Accumulation Accounts of all Participants who
     have not retired will be paid to those Participants by the Company as soon
     as practicable thereafter, provided that each such Participant shall have
     the option of requesting that the value of his Variable Accumulation
     Account be transferred to the Companion contract if such contract is being
     continued in effect, or to a regular non-participating department of the
     Company, for application to provide a deferred fixed annuity. The interest
     of all retired Participants in the Separate Account will be transferred by
     the Company to its regular non-participating department and applied to
     provided fixed annuities in the same form and on the same actuarial basis
     as the variable annuities then in effect for such Participants. To the
     extent permitted by the proceeds from liquidation, the amount of each fixed
     annuity shall be the same as the last variable payment received under the
     Contract.

5.08 NON-PARTICIPATING

     The Contract is Non-Participating and will be held with the other
     non-participating business of the Company.

                          PART VI - GENERAL PROVISIONS

6.01 CERTIFICATES

     The Company will issue to the Contractholder for delivery to each
     Participant an individual certificate setting forth a statement of the
     benefits to which he is entitled under the Contract.

6.02 REPORTS

     At least once in each Calendar Year after the first, the Company will
     inform the Participant of the then dollar value of his Variable
     Accumulation Account maintained under the Contract.

6.03 ASSIGNMENT OF BENEFITS

     The interest of either a Participant or a Beneficiary under the Contract
     may not be sold, assigned, discounted or pledged as collateral for a loan
     or as security for the performance of an obligation, or for any other
     purpose, to any person other than the Company. Such interest, benefits and
     payments will not be subject to any legal process to levy upon or attach
     the same for payment of any claim against any Participant or Beneficiary.

<PAGE>   15


6.04 BENEFICIARY

     Each Participant will have the right to designate the Beneficiary to whom
     any death benefit will be payable under the Contract. All Beneficiary
     designations must be made in writing and will be held by the Company.

     A Participant will have the right to change a designated Beneficiary at any
     time. However, if a change occurs on or after an annuity option is
     selected, it must be filed with the Company, and it will relate back to and
     take effect as of the date signed, without prejudice to the Company on
     account of any payments made by it before receipt of the request for change
     in Beneficiary. The interest of any Beneficiary who dies before the
     Annuitant will vest in the Participant, unless otherwise provided in the
     beneficiary designation.

6.05 FACILITY OF PAYMENT

     If the Company deems the recipient of any payment under the Contract to be
     legally incompetent, the Company will have the right, in settlement of full
     liability, to make the payment to a guardian, relative or other person. If
     a benefit is due to the death of a Participant, and no Beneficiary is
     named, or if the named Beneficiary has not survived, the Company may, in
     full discharge of its liability, pay the benefit to the Estate of the
     Participant.

6.06 PROOF OF AGE

     The Company reserves the right to require proof, satisfactory to it, of the
     age of any Participant and any joint annuitant prior to mailing the first
     payment on any annuity under the Contract.

6.07 MISSTATEMENTS AND ERRORS

     If the date of birth, sex or other information affecting the amount of a
     benefit is misstated, adjustments will be made by the Company to conform to
     the true facts. If the amount of any annuity has been understated, a single
     sum will be paid to the annuitant equal to the total in dollars of the
     errors in annuity payments made. If an overpayment is made, annuity
     payments will be suspended until the overpayment in dollars is recovered.
     If benefit overpayments are found to be unrecoverable, the Company will
     have no liability to the Contractholder or Participants if it made payments
     correctly based on the facts in its possession.

6.08 PREMIUM TAXES

     If the laws or regulations of any State or other jurisdiction require the
     payment of premium taxes upon receipt of contributions made under the
     Contract, the Company will have the right to deduct the applicable amounts
     from contributions or in such manner as may be required by the laws or
     regulations.

6.09 RESERVES

     Reserves for Variable Annuities will be computed on the Group Annuity Table
     for 1951 adjusted and projected with interest at the Assumed Investment
     Rate.

    otherwise indicated by the context, and the singular number shall to the
    same extent include the plural.

1.3 DETERMINATION OF BENEFITS

    All benefits for a Participant under this Contract shall be related to the
    value from time to time of his Individual Account as computed by the
    Company in the manner hereinafter provided. The size of a Participant's
    Individual Account hereunder will depend on the amount of funds transferred
    to it in accordance with the Plan, and the subsequent investment experience
    thereon, as hereinafter provided.

1.4 RETIREMENT BENEFIT

    A Participant shall be entitled to have provided under this Contract, a
    monthly Variable Annuity on the Normal Annuity Form, commencing at his
    Effective Annuity Date, and in an amount purchasable by his Individual
    Account when applied to the proper settlement rate table contained in Part
    IV of this Contract. Provided, that the initial monthly payment must be at
    least $20.00 in amount; if this condition cannot be met on the Normal Form,
    nor under any annuity option which the Participant is willing to elect, the
    value of the Participant's Individual Account shall, at the option of the
    Participant, be paid in a lump sum, or be transferred to the Companion
    Contract for payment in accordance with its terms.

1.5 ANNUITY OPTIONS

    A Participant may select any annuity option under this Contract if permitted
    by the Plan, and make changes therein, at any time, up to 30 days prior to
    the Effective Annuity Date. The amount of the annuity payable under such an
    option shall be determined by the Company from the amount of the
    Participant's Individual Account from the tables in Part IV. No such option
    may in any event be elected unless the first payment would be at least
    $20.00 in amount. Other conditions of payment applicable to each such option
    shall be set by the Company, and described in the annuity certificate. The 
    following annuity options are provided under this Contract.



                                      -2-
<PAGE>   4


1.5 ANNUITY OPTIONS (Continued)

    (1)   Life Ten Years Certain - A monthly income payable for life, with the
          guarantee that if death should occur PRIOR to the payment of 120
          installments, the remainder at the current payment level will be
          discounted at the reserve interest rate, and paid to the Beneficiary
          in a single sum. (This option will be the "Normal Annuity Form", or
          automatic option if the Plan does not specify otherwise.)

    (2)   Life Five Years Certain - A monthly income payable for life with a
          guarantee similar to that under the ten year certain form, but
          extending for five years from retirement.

    (3)   Life Without Refund - A monthly income payable for the life of the
          Participant only, in a higher amount than would be the case if there
          were a guaranteed number of payments.

    (4)   Joint and Survivor - A monthly income payable to the Participant for
          his life, and continued in the same number of Annuity Units after his
          death to a contingent annuitant, named at retirement, for the balance
          of the contingent annuitant's life.

    (5)   Fixed Installments - A level monthly income of a stipulated dollar
          amount, payable until the sum applied is exhausted.

    (6)   Fixed Period - A variable monthly income payable over a predesignated
          period of years, from one to twenty. 

          No option may be elected which has a certain period longer than the
          life expectancy of the Participant or the joint lives of the
          Participant and his spouse at the Effective Annuity Date on the basis
          of the mortality table used to determine the annuity payments.

          When the Plan provides for a qualified joint and survivor annuity as
          defined in the Employees' Retirement Income Security Act of 1974, the
          automatic annuity form under the Contract for each participant to whom
          such provision is applicable shall be an annuity for the life of the
          Participant with a survivor annuity for the life of his spouse which
          is not less than one-half, nor greater than, the amount of the annuity
          payable during the joint lives of the Participant and his spouse and
          which is the actuarial equivalent of a single life annuity for the
          life of the Participant.

1.6 DEATH OF PARTICIPANT

    On the death of a Participant prior to retirement, the value of his
    Individual Account on the Valuation Date next following the date written
    notice of the death is received in the Home Office of the Company shall be
    payable to his Beneficiary by the Company in a single sum.



                                      -3-
<PAGE>   5

1.6 DEATH OF PARTICIPANT (Continued)

    By written instructions for settlement, a Participant may elect to have the
    whole or any part of the death benefit paid to a Beneficiary under any of
    the retirement options in Section 1.5 above. Each monthly payment to be
    determined on the basis of the rates shown in the Tables in Part IV for the
    option elected, considering the Beneficiary to be one year younger than in
    actuality, as of the birthday nearest the Participant's death. Provided,
    however, that if such amount would provide less than $20.00 per month, it
    shall nevertheless be paid in a single sum. If no such election is in force
    at the time of the Participant's death, such election may be made by, but
    only for the benefit of, such Beneficiary.

1.7 OTHER TERMINATION

    On a termination of participation hereunder by a Participant other than
    through death or retirement, the Participant may elect any one of the
    following options, subject, however, in each case to the conditions and
    restrictions in the Plan.

    (1) Cash Settlement

        The value of the Participant's Individual Account on the Valuation Date
        written election of such option is received in the Home Office of the
        Company will be paid to him by the Company in a single sum.

    (2) Accumulation

        The Participant may allow his Individual Account to remain under the
        Contract, without further contributions, and with continued full
        participation in the investment experience hereof, for later payment in
        a lump sum on written election thereto, or (if at least $20.00 a month
        initially) as an annuity. Provided, that this option shall be available
        only if at the effective date of termination, the value of the
        Individual Account is not less than $2,000.00.

    (3) Transfer

        The Participant may have the value of his Individual Account transferred
        to the Companion Contract, for retention thereunder according to its
        terms. If the Plan limits the Participant to accumulation to a later
        retirement age, and the value of his Individual Account is less than
        $2,000.00 on the next following Valuation Date, such value shall be
        transferred by the Company to the Companion Contract, for retention or
        payment in accordance with its terms and the terms of the Plan.

In the event no election is received from a Participant on termination of
participation, Option (2) shall be automatic, unless the value of the Individual
Account is beneath the minimum, in which event the Company may apply the
transfer option.

If a portion of a Participant's Individual Account shall not be vested on
termination of employment, the value thereof shall be transferred to the
Companion Contract, and held by the Company thereunder for later application to
reduce subsequent contributions of the Employer.

1.8 PLAN AND TRUST

    The Company shall not be a party to the Plan, nor shall it be a party to any
    Trust which the Employer may, pursuant to the Plan, enter into under any
    Agreement of Trust. The Company shall be entitled to rely on the statements
    of the Employer relative to the terms of the Plan, without incurring any
    liability other than as specifically assumed under this Contract. The
    Company shall not be required without its written consent to recognize an
    amendment to the Plan or Trust which might act to increase its liability 
    hereunder.

1.9 COMMITTEE

    The general operation of Separate Account (B) shall be subject to periodic
    review by a Committee, elected by the Participants hereunder, together with
    Participants under similar contracts with the Company. The terms and
    conditions of the Committee's supervision over Separate Account (B) is set
    forth in a Management Agreement between the Company and Separate Account
    (B).

    In the event that the Participants under the Separate Account shall, through
    vote of a majority at interest, authorize the Committee to institute a
    change in the Management Agreement, any modification of this Contract
    required by the change shall be automatic and accomplished by appropriate
    endorsement.

2.1 APPLICATION

    The Contractholder shall, on the written election by a Participant, made in
    proper form, direct the Company to place some or all of the contributions
    made for the Participants placed in Separate Account (B) maintained by the
    Company, in lieu of being retained under the Companion Contract, subject to
    the provisions of the Contracts and the Plan. All assets deriving from a
    contribution placed under this Contract shall, from the next following
    Valuation Date, be subject to the special provisions of this Part II, as
    long as those assets remain in Separate Account (B).

2.2 TRANSFERS TO SEPARATE ACCOUNT (B)

    Current contributions or portions thereof which are designated by the
    Contractholder for investment in Separate Account (B) shall be transferred
    from the Companion Contract to the Separate Account as of the Valuation Date
    following receipt. Provided, that the Company shall not be required to make
    such transfer unless the Contractholder shall have furnished the Company
    with a detailed list of such contributions showing allocations among the
    Participants to which such contributions relate. The minimum single
    contribution allocable to a Participant shall be $10.00.

2.3 ACCUMULATION UNITS

    The assets of Separate Account (B) shall, for accounting purposes, be
    apportioned among equal units which shall be known as Accumulation Units.
    The interest of this Contract in Separate Account (B), and in the net
    earnings, and gains and losses, realized and unrealized, in Separate Account
    (B) shall be proportionate to the number of Accumulation Units credited
    hereto, compared to the total number of Accumulation Units then outstanding.

    The monetary value of an Accumulation Unit shall be defined arbitrarily as
    $1.00000 on June 30, 1966. The monetary value on each subsequent Valuation
    Date shall be found as hereinafter provided.

    The Company shall credit to this contract on account of each allocation made
    hereunder to the Separate Account, that number of Accumulation Units which
    the percentage of such allocation remaining after deduction of the following
    charge will purchase at the fair value of an Accumulation Unit on the
    Valuation Date of Allocation. A charge equal to the following percentage of
    each allocation shall not be placed in the Separate Account, but shall be
    held by the Company as part of its regular nonparticipating assets for
    present and future expenses hereto and for surplus and contingencies: 8.5%



                                      -6-
<PAGE>   8


2.3 ACCUMULATION UNITS (Continued)

    The value of each Individual Account under this Contract shall be measured
    by the number of Accumulation Units held to the credit of that Individual
    Account. The Company may maintain records of the Accumulation Units credited
    to each Individual Account, with the totals for all Individual Accounts
    hereunder being equal to the interest of this Contract in Separate Account
    (B). (For this purpose, Accumulation Units previously transferred to the
    Variable Annuity Account, to be defined, shall be excluded.)

    The Company may, by prior agreement with the Contractholder, make certain
    charges per Individual Account for accounting and administrative services.
    Any such charges shall be withdrawn from the Individual Accounts as due and
    transferred by the Company to its regular non-participating assets.

2.4 THE SEPARATE ACCOUNT

    All assets of the Separate Account are owned by the Company and the Company
    shall not be, nor hold itself out to be, a trustee with respect to such
    assets. The assets of the Separate Account equal to the reserves and other
    contract liabilities with respect to the Separate Account shall not be
    charged with liabilities arising out of any other business the Company may
    conduct.

2.5 VALUE OF ACCUMULATION UNITS

    The value of an Accumulation Unit on any Valuation Date is equal to the net
    asset value of the Separate Account divided by the number of Accumulation
    Units outstanding. The net asset value of the Separate Account is the market
    value of all securities and other assets, less liabilities of the Separate
    Account. Any income tax payable by the Company with respect to the assets of
    the Separate Account may be included with other liabilities in determining
    net asset value.

    Deductions will be made by the Company from the Separate Account for
    investment advisory fees and other charges and expenses under agreements
    between the Company and the Separate Account which are approved by the vote
    of a majority of the Participants in accordance with the Investment Company
    Act of 1940 as amended and which are described in current prospectuses for
    the Separate Account.

2.6 NUMBER OF ACCUMULATION UNITS

    The number of Accumulation Units credited to an Individual Account is
    determined by dividing the current contribution (less the percentage charge
    stated in Section 2.3) applicable to that Individual Account by the dollar
    value of an Accumulation Unit as of the date the contribution is applied.

2.7 TRANSFERS TO AND FROM COMPANION CONTRACT

    The Contractholder may, through written direction received by the Company,
    have any portion of the interest of this Contract in Separate Account (B)
    transferred to the Group Annuity Fund under the Companion Contract, provided
    that assets credited to the Variable Annuity account shall not be
    transferable, and that such transfers shall be subject to the prior consent
    of the Company.


                                      -7-
<PAGE>   9



2.7  TRANSFERS TO AND FROM COMPANION CONTRACT (Continued)

     Transfers of sums to this Contract from the Companion Contract may be made
     on termination of that Contract, and may be made otherwise prior to the
     Effective Annuity Date under special circumstances with the consent of the
     Company.

2.8  TERMINATION OF SEPARATE ACCOUNT PARTICIPATION

     The Contractholder may, as of any Valuation Date, through written notice
     received by the Company at least ten days before such date, elect to
     terminate participation of this Contract in Separate Account (B).
     Participation of the Contract in Separate Account (B) shall terminate
     automatically on the Valuation Date next following termination of the
     Companion Contract. Participation of the Contract in Separate Account (B)
     shall be immediately terminated on any finding by the District Director of
     the Internal Revenue that the annuity benefits hereunder do not meet the
     requirements of Section 401 of the Internal Revenue Code. On termination,
     each Participant shall have the same options with respect to his Individual
     Account as are provided in Section 1.7 of Part I on termination of
     participation at the election of the Participant, except that the
     "accumulation" option shall not be available if termination was due to tax
     disqualification.

2.9  VARIABLE ANNUITIES

     Variable Annuities may be provided eligible Participants from the interest
     of this Contract in Separate Account (B), subject to the other provisions
     of this Contract. Accumulation Units held as reserves for such Variable
     Annuities shall be separated by the Company from those held for future
     benefits of actively employed Participants, and credited to a Variable
     Annuity account. (This account shall also be credited with reserves for
     Variable Annuities provided under all other similar contracts issued by the
     Company, with all such reserves held in common.) The Company shall
     guarantee the mortality and future expense factors of Variable Annuities
     hereunder, but the investment element shall be directly related to the
     fair value from time to time of the Accumulation Units in the Variable
     Annuity account.

2.10 ANNUITY UNITS

     The amount of a Variable Annuity shall be measured in Annuity Units. The
     number of Annuity Units applicable to each such annuity shall be fixed at
     the Participant's Effective Annuity Date, and shall not change thereafter,
     unless the annuity shall be of such a form that the amount would change on
     the same circumstance if the annuity were a Fixed Annuity.

     The monetary value from time to time of an Annuity Unit shall depend on the
     current value of an Accumulation Unit, after an adjustment to reflect the
     annuity reserve interest rate. The monetary value of an Annuity Unit shall
     be defined arbitrarily at $1.00000 on January 1, 1966. On each succeeding
     first day of the month, the current monetary value of an Annuity Unit
     shall be found by multiplying the value as of the first day of the
     preceding month by the following factor:

        Monetary Value of an Accumulation Unit at end of previous month
        ---------------------------------------------------------------
                   1
                  --

                     second preceding month


                                      -8-
<PAGE>   10

2.10 ANNUITY UNITS (Continued)

     The ratio of such values of Accumulation Units (without the interest
     adjustment) shall be referred to as the "investment rate" for the month in
     question. The monetary value of each Annuity Unit shall be computed to the
     nearest thousandth of a cent.

2.11 PURCHASE OF VARIABLE ANNUITIES

     As of the Valuation Date immediately prior to a Participant's Effective
     Annuity Date, the number of Accumulation Units in a Participant's
     Individual Account shall be withdrawn by the Company from the account
     representing the regular interest of the Contract in Separate Account (B)
     and credited by the Company to the Variable Annuity account. A
     Participant's initial annuity payment shall then be determined by
     multiplying the value of his Individual Account in units of $1,000.00 as
     determined on the immediately preceding Valuation Date by the appropriate
     settlement option rate contained in Part IV of this Contract. The
     Participant's Variable Annuity shall then be translated into a permanent,
     fixed number of Annuity Units by dividing the initial annuity payment in
     dollars by the monetary value of an Annuity Unit on the Effective Annuity
     Date, with the result computed to the nearest one hundredth of a unit.

2.12 PAYMENT OF VARIABLE ANNUITIES

     Each Variable Annuity shall be paid to the Participant by the Company on
     the continuously varying basis previously defined. Prior to the due date of
     each Variable Annuity payment, the Company shall determine the monetary
     amount to be then payable by multiplying the number of Annuity Units
     provided by the Variable Annuity, by the monetary value of an Annuity Unit
     as of the first day of the previous month, and taking the product to the
     nearest cent.

     The Company shall guarantee the continued payment in full of the Annuity
     Units on each Variable Annuity under this Contract, for the payment period
     of the form of annuity involved. Not less frequently than once annually,
     the Company shall make a valuation of all Variable Annuities in course of
     payment hereunder. Any sum in excess of required reserves for future
     benefits may be removed by the Company from Separate Account (B) and added
     to its non-participating surplus of the required sum from its general
     nonparticipating surplus to Separate Account (B) for crediting to the
     Variable Annuity account of this Contract.

2.13 SINGLE SUM SETTLEMENTS UNDER VARIABLE ANNUITIES

     In the event that remaining guaranteed payments become payable in a single
     sum to a Beneficiary, the amount of the payment shall be found by first
     obtaining the single sum in terms of Annuity Units, by multiplying the
     amount of the annuity in Annuity Units, and the present value factor at
     3-1/2% per annum compound interest. The monetary amount of the settlement
     will then equal the amount in Annuity Units times the monetary value of an
     Annuity Unit on the first day of the month just preceding the date of
     settlement.


                                      -9-
<PAGE>   11
2.14 TRANSFER FROM COMPANY

     The Contractholder shall have the right to transfer away from the Company,
     in one sum on any Valuation Date, the entire interest of the Contract in
     Separate Account (B), excepting only funds held for terminated and retired
     Participants. In this event, the Company may deduct from the funds prior to
     transfer, a sum not greater than 2% thereof.

2.15 TERMINATION OF MANAGEMENT AGREEMENT

     In the event that the Committee, pursuant to the provisions of the
     Management Agreement between the Company and Separate Account (B), shall
     terminate the Management Agreement, the Company shall proceed as follows
     with respect to the interest of the Contractholder and Participants in
     Separate Account (B). All assets of Separate Account (B) shall be
     immediately liquidated by the Company. The values of the Individual
     Accounts of all Participants who have not retired, shall be paid to those
     Participants by the Company as soon as practicable thereafter. Provided,
     that each such Participant shall have the option of requesting that his
     share in the proceeds be transferred to the Companion Contract (if being
     continued) or to a regular nonparticipating department of the Company, for
     application to provide a deferred fixed annuity. The equitable shares in
     the proceeds of the Variable Annuity account shall be transferred by the
     Company to its regular non-participating department, and applied to provide
     fixed annuities to all retired Participants, in the same form, and on the
     same actuarial reserve bases as the Variable Annuities then in effect for
     the retired Participants. To the extent permitted by the proceeds from
     liquidation, the amount of each fixed annuity shall be the same as the last
     variable payment received under it.

                                    PART III

                               GENERAL PROVISIONS

3.1 ASSIGNMENT OF BENEFITS

     The interest of either a Participant or a Beneficiary under this Contract
     may not be sold, assigned, discounted or pledged as collateral for a loan
     or as security for the performance of an obligation, or for any other
     purpose, to any person other than the Company. Such interest, benefits and
     payments shall not be subject to any legal process to levy upon or attach
     the same, for payment of any claim against any Participant or Beneficiary.

3.2 CERTIFICATES

     When a Participant becomes entitled to an annuity benefit hereunder, the
     Company will issue an individual certificate to the annuitant describing
     the benefit.

3.3 ENTIRE CONTRACT

     The Contract and the Application, a copy of which is attached hereto, shall
     constitute the entire contract between the parties with respect to Separate
     Account (B) and Variable Annuities.

3.4 FACILITY OF PAYMENT

     In the event that the Company deems the recipient of any payment hereunder
     to be legally incompetent, the Company shall have the right, in settlement
     of full liability thereto, to make the payment to such guardian, relative
     or other person who, in the Company's opinion, is contributing toward the
     support of the recipient.

     If a benefit is due on the death of a Participant, and no Beneficiary shall
     be named, or if the named Beneficiary shall not survive, the Company may,
     in full discharge of its liability, pay such benefit to any one or more of
     surviving spouse, parents, children, brother or sister.

3.5 INCLUSION OF ADDITIONAL UNITS

     The Contractholder may, with the permission of the Company, include
     additional divisions, subsidiaries or other units under the control of the
     Contractholder, effective from any Anniversary Date.


                                      -11-
<PAGE>   13



3.6  INFORMATION

     The Contractholder shall furnish the Company in writing at its Home Office
     with the names and other data reasonably necessary for the administration
     of this Contract, and shall notify the Company of all changes affecting
     this Contract promptly in writing at its Home Office. The Company shall
     have no liability for the payment of any benefit with respect to which the
     Contractholder or a Participant has refused to furnish required
     information or to submit necessary forms.

3.7  MISSTATEMENTS AND ERRORS

     If the date of birth or other information affecting the amount of a benefit
     or premium is determined by the Company to have been misstated, adjustments
     shall be made by the Company so as to conform with the true facts. If the
     amount of an annuity has been understated, a single sum shall be paid to
     the annuitant equal to the total in dollars of the errors in annuity
     payments made; if an overstatement, annuity payments shall be suspended
     until the overpayment in dollars is recovered.

3.8  MODIFICATION OR AMENDMENT

     This Contract cannot be modified or amended, nor its provisions waived or
     extended, in any respect, except with the written consent of the Company,
     in compliance with the laws of the state in which this Contract is issued.
     Such written consent must be signed by the President, a Vice-President, the
     Secretary or an Assistant Secretary of the Company whose authority will not
     be delegated.

     With the written consent of the Company, the Contractholder may, at any
     time and from time to time, amend this Contract in any respect, without the
     consent of any Participant; provided that no such amendment shall deprive
     the Participant of any right to benefits accrued under this Contract as of
     the effective date of such amendment. The Company may amend the Contract
     to conform to applicable Federal or State laws or regulations or to changes
     in the operation of the Separate Account which have been approved by vote 
     of the Participants or by the Separate Account Committee.

3.9  NON-PARTICIPATING

     This Contract is non-participating and shall be held with the other
     non-participating business of the Company.

3.10 PROOF OF AGE

     Notwithstanding the other provisions of this Contract, no annuity shall be
     paid unless and until proof of date of birth for the Participant has been
     submitted to and accepted by the Company.

3.11 RESERVES

     Reserves for Variable Annuities shall be computed on the Group Annuity
     Table for 1951 adjusted and projected, with interest at three and one-half
     per cent per annum.

3.12 REVISION OF RATES

     The Company reserves the right to revise the annuity premiums herein or to
     change the deduction made from new allocations, subject to the following
     provisos. No revisions shall be made with respect to annuities in course of
     payment, nor shall any revisions be made with respect to the deduction from
     allocation of Participants who are covered during the first five contract
     years. No revision in premium rates shall be made with respect to
     Participants born prior to January 1, 1907. Further, the Company guarantees
     that the rates applicable to other Participants covered in the first five
     contract years shall not exceed the rates resulting from the following
     modifications of those of Table 4.1:

<TABLE>
<CAPTION>
For Participants Born in Period            Adjustment
- -------------------------------            ----------
<S>                                        <C>
1-1-07 to 12-31-16, inclusive              Rate down one year in age.
1-1-17 to 12-31-26      "                  Rate down two years in age.
1-1-27 and later                           Rate down three years in age.
</TABLE>

     Notwithstanding the foregoing, the Company does not in any event guarantee
     the annuity rates of this Contract with respect to any funds which the
     District Director of Internal Revenue finds not to meet the requirements of
     Section 401 of the Internal Revenue Code.

3.13 SETTLEMENTS ON DEATH

     Each Participant shall name a Beneficiary, with respect to any benefit
     payable hereunder on the death of the Participant. Designations of
     Beneficiary shall be made in writing, and shall be held by the Employer,
     except for those to be applicable after the retirement of a Participant,
     which shall be filed with the Company, in a form satisfactory to the
     Company.

     A Participant may change a designation of Beneficiary at any time through a
     similar procedure. Provided that if a change is required to be filed with
     the Company, then on filing it shall relate back to and take effect as of
     the date signed, without prejudice to the Company on account of any
     payments made by it before receipt of such request.

3.14 ANNUAL REPORTS

     The Company will furnish the Contractholder hereunder not less frequently
     than annually a statement in writing as to the current value of all
     Individual Accounts under this Contract.

Age is age attained on birthday nearest to Effective Annuity Date. These rates
are guaranteed for all annuity purchases under the Contract for Participants
born prior to January 1, 1907, and for other Participants subject to the
provisions of Section 3.12.

The above rates are applicable where the Company is not required to pay a state
premium tax at the time of annuity purchase. Where such a tax is payable, the
rates shall be adjusted by the amount of tax.

               [For use with 403(b) Plan Contracts with the Joint
              Retirement Board of the Rabbinical Assembly, et al.]

                      [CNA INSURANCE COMPANIES LETTERHEAD]


                              ENROLLMENT STATEMENT


I, _________________, have read and understand the following feature of an
investment under a 403(b) Plan as more fully described in the Prospectus for
Continental Assurance Company Separate Account (B) (the "Separate Account"):

I.  WITHDRAWALS

    Distributions may not be made to any Participant of a 403(b) Plan prior to
    attainment of age 59 1/2 unless the Participant is permanently and totally
    disabled, is subject to a certain form of hardship or such distributions to
    the Participant are attributable to separation from service after age 55.
    Distributions are also permissible upon the death of the Participant.

II. ANNUITIES

    After a Participant has selected a retirement date, the Participant must
    also select an annuity option. An annuity is a series of payments for life;
    for life with either a minimum number of payments or a determinable sum
    guaranteed; or for the joint lifetime of the person receiving payments and
    another person and thereafter during the lifetime of the survivor. The
    Participant has two types of annuities to choose from:

     a. Variable annuity - an annuity which provides for payments varying in
        amount in accordance with the investment experience of the Separate
        Account.

     b. Fixed annuity - an annuity which provides for payments which remain
        fixed throughout the payment period and which do not vary with the
        investment experience of the Separate Account.

The company currently has a charge for the purchase of a fixed rate annuity.

Changes to annuity options may be made up to 30 days prior to the date annuity
payments are to begin.

III. FUND TO FUND ACTIVITY

     Prior to commencement of annuity payments, a Participant may transfer funds
     between fixed and variable contracts. Some of the 403(b) Plan Contracts
     provide that such transfers will be made without charge. Others provide
     that the company may make a charge of $10 for the second and each
     succeeding transfer in any calendar year. Please refer to your Contract to
     determine the applicability of such fee.

     A Participant may change the percentage allocation of future purchase
     payments between fixed and variable annuity contracts at any time without
     charge.
