     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.

     Because this is only a summary, it does not contain all the information

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.

     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

     charge) of 2% of the Purchase Payments received prior to withdrawal when
     your Account is terminated and the entire interest in the Contract is

                             that was organized under the Illinois Insurance

                             403(b) Plan Contract with the Joint Retirement
                             Board, CAC does not deduct any charge for sales and

                             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 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

                             minimum Purchase Payment on Contracts for HR-10
                             Plans.
    
 
   
INVESTMENT OBJECTIVES......  Separate Account (B) invests its assets primarily
                             in common stocks and securities convertible into
                             common stocks. The primary investment objective of
                             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
by reference herein is the equivalent of net assets.
 
   
     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>

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).

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.

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.

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:

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.

<PAGE>   27
 
   
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.

     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

                                 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.

 *  An "interested person" (as defined in Section 2(a)(19) of the 1940 Act), by
    virtue of his or her employment with CAC.
    
 
   
 (1)  CNA Financial, CNA Plaza, Chicago, Illinois 60685, owns all of 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.

     The payment of fees to Committee Members is one of the items of expense for
which CAC receives a monthly investment advisory fee (at the annual rate of 0.5%
of the average daily net asset value of Separate Account (B)) from Separate
Account (B) pursuant to CAC's Investment Advisory Agreement with Separate
Account (B).
    
 
   
     The following table sets forth information regarding the compensation of
all Committee Members of Separate Account (B) for services rendered in 1998 to
Separate Account (B) and to funds deemed to be included in the same fund complex
as Separate Account (B). A "fund complex" for this purpose means any two or more
funds that hold themselves out to investors as related companies or that have a
common or related investment adviser.

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
<PAGE>   53
 
   
$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 has 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.

     CAC may be deemed to be the principal underwriter for Separate Account (B),
but receives no compensation from Separate Account (B) other than the fees
pursuant to the Investment Advisory Agreement and the Administrative Service
Agreement. The Contracts are offered by employees and licensed agents and
brokers of CAC, who may be deemed to be "underwriters" under the Securities Act
of 1933. Commissions to such persons on the sale of the Contracts may be
considered "underwriting commissions".

CONTINENTAL ASSURANCE COMPANY SEPARATE ACCOUNT (B) (the "Separate Account") and
CONTINENTAL ASSURANCE COMPANY (the "Company").

               of Variable Annuity Contracts, which are funded by the Separate
               Account: level deduction contracts, graded deduction contracts
               and contracts by which self-employed individuals may provide

               ("HR-10" plans).  The Company is contractually obligated under
               said contracts to provide sales and administrative services for
               the sales and administrative fees specified in each individual
               contract.  Said fees are deducted from each purchase payment as
               it is received.  In the event that said fees exceed the Company's
               costs, any excess will inure to the Company as a profit.  The
               Company agrees to continue such service to all Participants to
               whom it is contractually bound for the fees specified in the
               contracts."

     2.   All other provisions of the Agreement shall remain in full force and

to such papers executed by the Company as may be necessary or customary.


ARTICLE IX. EXECUTION OF DOCUMENTS.

SECTION 1. EXECUTION. The Chairman of the Board of Directors, and President or a
Vice President shall have the power to bind the Company upon any and all
policies of insurance, contracts, bonds, undertakings and other obligatory
instruments by his signature and execution thereof attested by the signature of
the Secretary or of an Assistant Secretary and such execution of any such
instrument shall be deemed to be the act of the Company. Such signatures, when
authorized by the Board of Directors, may be engraved or printed facsimiles.

SECTION 2. FACSIMILES. Where engraved or printed facsimile signatures are used
on policy forms, checks, receipts or other instruments issued or delivered by
the Company, such policy forms, checks, receipts or other instruments bearing
the facsimile signature of a deceased, retired, or disabled officer may

of such officer with the same effect as if such officer were not deceased,
retired or disabled.

Directors, the President or a Vice President may from time to time, appoint by
written certificates attorneys-in-fact to act in behalf of the Company in the
execution of policies of insurance, bonds, undertakings and other obligatory
instruments of like nature. Such attorneys-in-fact, subject to the limitations
set forth in their respective certificates of authority shall have full power to

Certificates representing shares of the Company shall be in such form,
consistent with the law and the Articles of Incorporation, as shall be approved
by the Board of Directors. They shall be consecutively numbered in the order of
their issue and shall be signed by the Chairman of the Board of Directors, the
President, or a Vice President and by the Secretary or an Assistant Secretary,
and shall be sealed with the corporate seal of the Company. Such seal and the
signatures of such officers of the Company, or any of them, may be engraved or
printed facsimiles, if such certificates are signed by a transfer agent or
registered by a registrar appointed by the Board of Directors. In case any
officer who shall have signed any such certificate, or whose facsimile signature
shall have been used thereon, shall cease to be such officer before such
certificate shall have been issued by the Company, such certificate may,
nevertheless, be used by the Company with the same effect as if such officer had
not ceased to be such at the date of issuance of such certificate.

The Board of Directors may appoint a transfer agent by whom the shares of the
Company may be transferred and also a registrar, by whom the shares may be
registered and in the event of such appointments, no certificate for shares of

assigned and upon such surrender a new certificate shall be issued to the
assignee signed as provided in Article X. The surrendered certificate shall be
canceled and delivered to the Secretary who shall preserve the same. In the
event that a certificate has been lost, mislaid, stolen or destroyed, upon
written request of the owner thereof, a replacement certificate may nevertheless
be issued in lieu thereof, in the exercise of the Company's discretion, which
shall be evidenced by a letter signed by the Chairman of the Board of Directors,
the President, or any Vice President, provided that prior to such issue a surety
bond, in form approved by the General Counsel, be furnished for the protection
of the Company, its transfer agent, if any, and its registrar.

SECTION  2.  CLOSE OF  TRANSFER  BOOKS.  The  Board  of  Directors  may,  in its
discretion,   close  the   transfer   books  as  provided  in  the  Articles  of
Incorporation.

SECTION 3. HOLDERS OF RECORD. The Company shall be entitled to treat the holder
of record of any share or shares as the holder in fact thereof and accordingly

have express or other notice thereof.

                                    AGREEMENT


     Agreement made this 7th day of February, 1985 by and between Continental
Assurance Company Separate Account (B) (the "Separate Account") and Continental
Assurance Company (the "Company").

     1. CNA Investor Services, Inc. ("ISI") is an affiliate of the Company.
Within twenty days after the effective date of this Agreement, the Company will
enter into an agreement with ISI whereunder ISI will report quarterly to the
Company the ISI's net profits as defined in Paragraph 3 hereof in connection
with brokerage services provided by ISI for the Separate Account. ISI will keep
such books and records as are necessary to facilitate such reporting, and such
books and records will be made available to the Company and the Separate Account
for inspection upon reasonable notice to ISI.


     2. Subject to its primary obligation to obtain the best execution and price
possible for each brokerage transaction, and its unqualified discretion in the
case of any brokerage transaction to choose any exchange or no exchange for the
execution of the transaction, and recognizing that in many situations, secrecy,
speed and other facts have a bearing on the circumstances of a transaction, the
Company agrees that it will endeavor to make use of the brokerage facilities of
ISI for portfolio brokerage transactions of the Separate Account when such use
is in the best interest of the Separate Account. The Company agrees that an
amount equal to the "net profits" as defined in Paragraph 3 hereof derived by
ISI quarter shall be credited by the Company against the investment advisory fee
payable to the Company by the Separate Account as soon as the amount of such
fees are ascertainable.


     3. "Net profits" as used in Paragraphs 1 and 2 hereof shall mean the amount
if any, by which the following credits exceed the following debits:


          (a) Gross revenues of ISI derived from its execution of portfolio
     brokerage transactions on behalf of the Separate Account will be credited.


          (b) Direct expenses, as defined in subparagraph (c) (1) herein, of
     transactions described in paragraph (a) herein, will be debited.


          (c) As used herein, the following phrases shall have the following
     meanings:


               (1) "Direct expenses" includes all expense items characterized as
          "direct" in accordance with good accounting practice and specifically
          includes, but is not limited to, applicable floor brokerage fees,
          clearing brokers' fees, commissions on forwarded orders, transfer
          taxes, exchange fees, interest charges directly applicable to a
          transaction, and other fees and charges relating to brokerage
          transactions.

     4. This Agreement shall be effective with respect to "net profits" derived
by ISI as defined in Paragraph 3 from Separate Account portfolio brokerage
transactions made after February 7, 1985. Such "net profits" shall be credited
against the investment advisory fee payable to the Company by the Separate
Account as soon as the amount of such fees are ascertainable.

Dear Participant:
- --------------------------------------------------------------------------------
 
   Continental Assurance Company Separate Account (B) ended the year with an
Accumulated Unit Value increase of 21.82% while the dividend-adjusted Standard &
Poor's Composite Index of 500 stocks (S&P 500) increased by 28.58%. The average
stock fund, as reported in the Wall Street Journal, gained 14.52% and the
average growth fund returned 19.37% during 1998.
   The market advance was quite narrow in 1998 with the average stock in the S&P
500 gaining just 10.80%. The difference in growth rates between the index and
the average is a result of the index being capitalization weighted. The largest
stocks with the strongest growth rates have continued to trade at higher
multiples to their earnings and growth rates. According to data going back to
1958, compiled by the Leuthold Group and reported in the Wall Street Journal,
the differential between the S&P 500 and the average stock in the index has
never been as large. Other indexes bear out this conclusion as well. The Dow
Jones Industrial Average, still more reflective of slower growth, large
industrial companies, returned 18.13% and the Russell 2000, a small company
index, actually had a negative return of 2.24%.
   1998 experienced a record fourth consecutive year of the S&P 500 gaining in
excess of 20%. This strong bull market was originally driven by a cyclical
improvement in earnings and moderating interest rates. Following a sharp but
short summer correction of about 20% the Federal Reserve eased short term
interest rates three times which placed the market back on an upside trajectory.
With earnings gains slowing and long-term interest rates above their summer
lows, the driving force in the fourth quarter was market liquidity.
   Separate Account (B) has concentrated its investments generally in large
capitalization companies. At December 31, 1998, the investment portfolio had a
median capitalization of approximately $25 billion. The fund owns stocks of
three companies with capitalizations in excess of $200 billion, Microsoft,
General Electric and Intel, and another six companies with capitalizations
exceeding $100 billion. Only three of the fund's holdings could be considered
small capitalization companies with less than $1 billion in market value, Emmis
Broadcasting, Intermedia Communications and Robert Mondavi. Separate Account (B)
has favored investments in technology and health care companies as well as a
blend of multinational companies. Management believes that the U.S. does
technology better than anyone else and that health care companies, particularly
pharmaceuticals, will continue to benefit as the population in industrial
countries continues to age. The large multinational companies will ultimately
benefit from the faster economic growth in emerging markets.
   Separate Account (B) has taken advantage of the market's volatility by
employing a disciplined program of writing call options on stocks held in the
portfolio. During 1998 we generated $1.387 million in call premiums compared to
$986 thousand in 1997. We intend to judiciously use this strategy to enhance
income generation in 1999.
   1999 could be a challenging year. Historically, the average return for the
stock market has been about 12.5%, well below the average of the last four
years. The S&P 500 price/ earnings multiple of approximately 25 times 1999
projected earnings is high historically and leaves little room for earnings
disappointments. Earnings are expected to be up, but only moderately in the 3%
to 7% range. If inflation continues to be subdued, the Federal Reserve will
probably not tighten monetary policy. In this economic environment, we currently
expect a positive, but more moderate stock market return than we have had over
the past four years. Because of the high market valuation, continued volatility
can be anticipated. Although we do not expect corrections to exceed 10%, any
move by the Federal Reserve to reduce liquidity would probably result in a
larger market adjustment.
   Management will continue to closely monitor market conditions and make
portfolio changes that we believe will enhance relative returns. Thank you for
your continued support and participation.
 
Cordially,
 
Marilou R. McGirr
Marilou R. McGirr
Chairman of the Committee

- --------------------------------------------------------------------------------
                    NOTE 1. SIGNIFICANT ACCOUNTING POLICIES:
- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------
 
ORGANIZATION
   Continental Assurance Company Separate Account (B) is registered under the
Investment Company Act of 1940, as amended, as an open-end diversified
management investment company. Separate Account (B) is part of Continental
Assurance Company (CAC), an Illinois life insurance company which is a wholly-
owned subsidiary of Continental Casualty Company (Casualty). Casualty is
wholly-owned by CNA Financial Corporation (CNA). Loews Corporation owns
approximately 85% of the outstanding common stock of CNA.
   The operations of CAC include the sale of certain variable annuity contracts,
the proceeds of which are invested in Separate Account (B). CAC also provides
investment advisory and administrative services to Separate Account (B) for a
fee.
   The assets and liabilities of Separate Account (B) are segregated from those
of CAC.
 
INVESTMENTS
   Investments in securities traded on national securities exchanges are valued
at the last reported sales price. Securities not traded on a national exchange
are valued at the bid price of over-the-counter market quotations. Short-term
notes are valued at cost plus accrued discount or interest (amortized cost)
which approximates market.
   Net realized gains and losses on sales of securities are determined as the
difference between proceeds and cost, using the specific identification method.
There are no differences in cost for financial statement and Federal income tax
purposes.
   Security transactions are accounted for on the trade date. Dividend income is
recorded on the ex-dividend date.
   Separate Account (B) may loan securities, up to a maximum of 25% of its net
assets, to brokers under loan agreements which are fully secured by cash or
government securities. Loaned securities are not reported herein as purchases or
sales since Separate Account (B) remains the owner of loaned securities. During
the years ended December 31, 1998 and 1997 no investment securities owned by
Separate Account (B) were loaned to brokers under loan agreements.
 
FEDERAL INCOME TAXES
   Under existing Federal income tax law, no taxes are payable by Separate
Account (B) on net investment income and net realized capital gains, which are
reinvested in Separate Account (B) and taken into account in determining unit
values.
 
OTHER
   The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

     Separate Account (B) invests from time to time in certain derivative
financial instruments, namely put and call options, to increase investments
returns.
 
     Derivatives are carried at fair value which generally reflects the
estimated amounts that Separate Account (B) would receive or pay upon
termination of the contracts at the reporting date. Dealer quotes are available
for all of Separate Account (B)'s derivatives.
 
     The fair values associated with these instruments are generally affected by
changes in the stock market. The credit risk associated with these instruments
is minimal as all transactions are cleared through security exchanges.
 
     A summary of the aggregate notional amounts and estimated market values of
call options at December 31, 1998, as well as the monthly average market values
and the recognized gain, are presented below.

The Committee Members and the Participants of
Continental Assurance Company Separate Account (B)
 
     We have audited the accompanying statement of assets and liabilities,
including the schedule of investments as of December 31, 1998, of Continental
Assurance Company Separate Account (B) (a separate account of Continental
Assurance Company [the Company], which is an affiliate of CNA Financial
Corporation, an affiliate of Loews Corporation) as of December 31, 1998 and
1997, and the related statements of operations and changes in participants'
equity for the years then ended, and the financial highlights (shown on page
two) for each of the five years in the period ended December 31, 1998. These
financial statements and financial highlights are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.
     We conducted our audits in accordance with generally accepted auditing
standards. These standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of December 31, 1998, by correspondence with
the custodian and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
     In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Continental Assurance Company Separate Account (B) as of December 31, 1998 and
1997, the results of its operations and changes in its participants' equity for
the years then ended and the information included in the financial highlights
for each of the five years in the period ended December 31, 1998, in conformity
with generally accepted accounting principles.

     MANAGEMENT'S DISCUSSION OF 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 Continental Assurance Company (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 Corporation (CNA)
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). While there is no client charge to Separate Account (B),
CNA 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 has spent approximately $59 million on Year 2000
readiness matters.
 
     CNA 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) management believes that the systems on which it relies do not have any
significant remaining exposure to the Year 2000 issue and, therefore, Separate
Account (B) does not have material exposure to the Year 2000 issue. However, due
to the interdependent nature of computer systems, there may be an adverse impact
on Separate Account (B) if banks, independent agents, vendors, insurance agents,
third party administrators, various governmental agencies and other business
partners fail to successfully address the Year 2000. To mitigate this impact,
CNA is communicating with these various entities to coordinate Year 2000
conversion.
 
     In addition, CNA 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.
