BOND DEBENTURE FUND

Bond Debenture Fund's 1998 Semi-Annual Report to shareholders, including its
financial highlights section, when filed with the SEC, is hereby incorporated by
reference into this Prospectus.

4 HOW WE INVEST
  ==============================================================================

The Affiliated Fund. We believe that investors purchase and redeem shares to
meet long-term financial objectives rather than to take advantage of price
fluctuations, and that these requirements will best be met by an investment
seeking capital appreciation with less fluctuations in market value than the
Standard & Poor's 500 Stock Index. For this reason, the Affiliated Fund tries to
keep its assets invested in securities which are selling at reasonable prices
and, therefore, is willing to forgo some opportunities for gains when, in
managements judgment, they carry excessive risk.

      We try to anticipate major changes in the economy and select stocks which
we believe will benefit most from these changes. We also look for positive
change within market sectors, industries and individual companies.

      Normally we invest in large, seasoned companies, in sound financial
condition, issuing common stocks (including securities convertible into common
stocks) which are expected to perform above average with respect to earnings and
price appreciation. Although the prices of common stocks fluctuate and their
dividends vary, historically, common stocks have appreciated in value and their
dividends have increased when the companies they represent have prospered and
grown.

      We constantly balance the opportunity for profit against the risk of loss.
In the past, very few industries have continuously provided the best investment
opportunities. We believe it is important to take a flexible approach and adjust
the portfolio to reflect changes in the opportunities for sound investment
relative to the risks assumed. Therefore, we sell securities that we judge to be
overpriced and reinvest the proceeds in other securities which we believe offer
better value.

      For income and flexibility, we may (a) write covered call options traded
on a national securities exchange with respect to securities in our portfolio,
(b) invest up to 10% of our net assets (at the time of investment) in foreign
securities and (c) invest in straight bonds or other debt securities, including
lower rated, high-yield bonds. We do not intend to write covered call options
with respect to securities with an aggregate market value of more than 10% of
our gross assets at the time an option is written. We will not invest more than
5% of our net assets (at the time of investment) in lower rated (BB/Ba or
lower), high-yield bonds.

The Small-Cap Series. We will attempt to achieve the Series' objective by
investing primarily in a carefully selected portfolio of common stocks. Dividend
and investment income are of incidental importance, and the Series may invest in
securities which do not produce any income. Although the Series typically will
hold a large, diversified number of securities identified through a
quantitative, value-driven investment strategy, it does entail above-average
investment risk in comparison to the overall U.S. stock market. Shares of the
Series should be purchased with a long-term view in mind.

      The stocks in which the Small-Cap Series generally invests are those
which, in Fund management's judgment, are selling below intrinsic value and at
prices that do not adequately reflect their long-term business potential.
Selected smaller stocks may be undervalued because they are often overlooked by
many investors, or because the public is overly pessimistic about a company's
prospects. Accordingly, their prices can rise either as a result of improved
business fundamentals, particularly when earnings grow faster than general
expectations, or as more investors come to recognize the full extent of a
company's underlying potential. The price of shares in relation to book value,
sales, asset value, earnings, dividends and cash flow, both historical and
prospective, are key determinants in the security selection process. These
criteria are not rigid, and other stocks may be included in the Series'
portfolio if they are expected to help it attain its objective. These criteria
can be changed by the Fund's Board of Directors.

      The Small-Cap Series also may invest in preferred stocks and bonds, which
have either attached warrants or a conversion privilege into common stocks. In
addition, the Series may purchase options on stocks that it holds as protection
against a significant price decline; purchase and sell stock index options and
futures to hedge overall market risk and the investment of cash flows; and write
listed put and listed covered call options. See "Options Transactions" and
"Stock Index Futures" below.

      Under normal circumstances, at least 65% of the Series' total assets will
be invested in common stocks issued by smaller, less well-known companies (with
market capitalizations of less than $1 billion) selected on the basis of
fundamental investment analysis. The Series may, however, invest up to 35% of
its total assets in the


                                                                               5
<PAGE>

securities of any issuer without regard to its size or the market capitalization
of its common stock. Companies in which the Small-Cap Series is likely to invest
may have limited product lines, markets or financial resources and may lack
management depth or experience. The securities of these companies may have
limited marketability and may be subject to more abrupt or erratic market
movements than securities of larger, more established companies or the market
averages in general.

      Options Transactions. The Small-Cap Series may purchase and write (i.e.,
sell) put and call options on equity securities or stock indices that are traded
on national securities exchanges. A call option on equity securities gives the
purchaser, in return for a premium paid, the right for a specified period of
time to purchase the securities subject to the option at a specified price (the
"exercise price" or "strike price"). The writer of a call option, in return for
the premium, has the obligation, upon exercise of the option, to deliver,
depending upon the terms of the option contract, the underlying securities to
the purchaser upon receipt of the exercise price. When the Series writes a call
option, it gives up the potential for gain on the underlying securities in
excess of the exercise price of the option during the period that the option is
open.

      A put option on equity securities gives the purchaser, in return for a
premium, the right, for a specified period of time, to sell the securities
subject to the option to the writer of the put at the specified exercise price.
The writer of the put option, in return for the premium, has the obligation,
upon exercise of the option, to acquire the securities underlying the option at
the exercise price. The Series, as the writer of a put option, might therefore
be obligated to purchase underlying securities for more than their current
market value.

      Options on stock indices are similar to options on equity securities
except that, rather than the right to take or make delivery of stock at a
specified price, an option on a stock index gives the holder the right, in
return for a premium paid, to receive, upon exercise of the option, an amount of
cash if the closing level of the stock index upon which the option is based is
greater than, in the case of a call, or less than, in the case of a put, the
exercise price of the option. The writer of an index option, in return for a
premium, is obligated to pay the amount of cash due upon exercise of the option.

      The Small-Cap Series will write only "covered" options. An option is
covered if, so long as the Series is obligated under the option, it owns an
offsetting position in the underlying securities or maintains cash, U.S.
Government securities or other liquid high-grade debt obligations with a value
sufficient at all times to cover its obligations in a segregated account. See
"Investment Policies -- Limitation on Purchases and Sales of Stock Options,
Options on Stock Indices and Stock Index Futures" in the Statement of Additional
Information.

      There is no limitation on the amount of call options the Small-Cap Series
may write. The Series may only write covered put options to the extent that
cover for such options does not exceed 25% of the Series' net assets. The Series
will not purchase an option if, as a result of such purchase, more than 20% of
its total assets would be invested in premiums for such options.

      Stock Index Futures. The Small-Cap Series may purchase and sell stock
index futures, which are traded on a commodities exchange or board of trade for
certain hedging and risk management purposes, in accordance with regulations of
the Commodities Futures Trading Commission.

      A stock index futures contract is an agreement in which one party agrees
to deliver to another an amount of cash equal to a specific dollar amount times
the difference between a specific stock index at the close of the last trading
day of the contract and the price at which the agreement is made. No physical
delivery of the underlying stocks in the index is made.

      The Series may not purchase or sell stock index futures if, immediately
thereafter, more than one-third of its net assets would be hedged. In addition,
except in the case of a call written and held on the same index, the Series will
write call options on indices or sell stock index futures only if the amount
resulting from the multiplication of then current level of the index (or
indices) upon which the options or futures contract(s) is based, the applicable
multiplier(s), and the number of futures or options contracts which would be
outstanding would not exceed one-third of the value of the Series' net assets.

      The Small-Cap Series' ability to enter into stock index futures and listed
options is limited by the requirements of the Internal Revenue Code of 1986, as
amended (the "Internal Revenue Code"), for qualification, as a regulated
investment company. See "Taxes" in the Statement of Additional Information.

      Foreign Investments. Up to 35% of the Small-Cap Series' net assets (at the
time of investment) may be invested in securities (of the type described above)
that


6
<PAGE>

are primarily traded in foreign countries. See "Risk Factors Common to Each
Fund" below.

      Forward Foreign Currency Contracts. The Small-Cap Series may utilize a
forward foreign currency contract which involves an obligation to purchase or
sell a specific amount of a currency at a set price on a future date. The Series
may enter into forward foreign currency contracts in primarily two
circumstances. First, when the Series desires to "lock in" the U.S. dollar price
of the security, by entering into a forward contract for the purchase or sale of
the amount of foreign currency involved in the underlying security transaction,
the Series will be able to protect against a possible loss resulting from an
adverse change in the relationship between the U.S. dollar and the subject
foreign currency during the period between the date of purchase or sale and the
date of settlement.

      Second, when Fund management believes that the currency of a particular
foreign country may suffer a decline against the U.S. dollar, the Series may
enter into a forward contract to sell the amount of foreign currency
approximating the value of some or all of the portfolio securities denominated
in such foreign currency or, in the alternative, may use a
cross-currency-hedging technique whereby it enters into such a forward contract
to sell another currency (obtained in exchange for the currency in which the
portfolio securities are denominated if such securities are sold) which it
expects to decline in a similar manner but that has a lower transaction cost.
Precise matching of the forward contract and the value of the securities
involved will generally not be possible.

      Foreign Currency Put and Call Options. The Small-Cap Series also may
purchase foreign currency put options and write foreign currency call options on
U.S. exchanges or U.S. over-the-counter markets (OTC options are generally less
liquid and involve issuer credit risk). A put option gives the Series, upon
payment of a premium, the right to sell a currency at the exercise price until
the expiration of the option and serves to insure against adverse currency price
movements in the underlying portfolio assets denominated in that currency. The
premiums paid for such foreign currency put options will not exceed 5% of the
net assets of the Series.

      A foreign currency call option written by the Small-Cap Series gives the
purchaser, upon payment of a premium, the right to purchase from the Series a
currency at the exercise price until the expiration of the option. The Series
may write a call option on a foreign currency only in conjunction with a
purchase of a put option on that currency ("cross hedging"). Such a strategy is
designed to reduce the cost of downside currency protection by limiting currency
appreciation potential. The face value of such writing or cross-hedging
(described above) may not exceed 90% of the value of the securities denominated
in such currency (a) invested in by the Series to cover such call writing or (b)
to be crossed.

      The Small-Cap Series may engage in (a) investing in closed-end investment
companies, (b) investing in straight bonds or other debt securities, including
lower rated, high-yield bonds, (c) lending of its portfolio securities to
broker-dealers on a secured basis and (d) investing in rights and warrants to
purchase securities (included within these purchases, but not exceeding 2% of
the value of the Series assets, may be warrants which are not listed on the New
York or American Stock Exchanges), but the Series has no present intention to
commit more than 5% of gross assets to any one of these four identified
practices. The Series will not invest more than 5% of its assets (at the time of
investment) in lower rated (BB/Ba or lower), high-yield bonds.

      Repurchase Agreements. The Small-Cap Series may, on occasion, enter into
repurchase agreements whereby the seller of a security agrees to repurchase that
security at a mutually agreed-upon time and price. The period of maturity is
usually quite short, possibly overnight or a few days, although it may extend
over a number of months. The resale price is in excess of the purchase price,
reflecting an agreed-upon rate of return effective for the period of time the
Series' money is invested in the security. The Series' repurchase agreements
will at all times be fully collateralized in an amount at least equal to the
purchase price, including accrued interest earned on the underlying securities.
The instruments held as collateral are valued daily, and if the value of the
instruments declines, the Series will require additional collateral. If the
seller defaults and the value of the collateral securing the repurchase
agreement declines, the Series may incur a loss.

      When Issued or Delayed Delivery Transactions. The Small-Cap Series may
purchase or sell securities on a when-issued or delayed delivery basis.
When-issued or delayed delivery transactions arise when securities are purchased
or sold by the Series with payment and delivery taking place as much as a month
or more in the future in order to secure what is considered to be an


                                                                               7
<PAGE>

advantageous price and yield to the Series at the time of entering other liquid
high-grade debt obligations having a value equal to or greater than the Series'
purchase commitments; the custodian will likewise segregate securities sold on a
delayed delivery basis. The securities so purchased are subject to market
fluctuation and no interest accrues to the purchaser during the period between
purchase and settlement. At the time of delivery of the securities the value may
be more or less than the purchase price and an increase in the percentage of the
Series' assets committed to the purchase of securities on a when-issued or
delayed delivery basis may increase the volatility of the Series' net asset
value.

      Short Sales. The Small-Cap Series may make short sales of securities or
maintain a short position, provided that at all times when a short position is
open the Series owns an equal amount of such securities or securities
convertible into or exchangeable, without payment of any further consideration,
for an equal amount of the securities of the same issuer as the securities sold
short (a "short sale against-the-box"). Short sales will be made primarily to
defer realization of gain or loss for federal tax purposes. The Series does not
intend to have more than 5% of its net assets (determined at the time of the
short sale) subject to short sales against-the-box.

      The staff of the SEC has taken the position that purchased OTC options and
the assets used as "cover" for written OTC options are illiquid securities
unless the Series and the counterparty have provided for the Series, at the
Series' election, to unwind the OTC option. The exercise of such an option
ordinarily would involve the payment by the Series of an amount designed to
reflect the counterparty's economic loss from an early termination, but does
allow the Small-Cap Series to treat the assets used as "cover" as "liquid."

Risk Factors. Although the Series may invest, from time to time, in stocks of
large-sized and small-sized companies guided by the policies mentioned above,
the small capitalized companies in which it primarily invests may offer
significant appreciation potential. However, smaller companies may carry more
risk than larger companies. Generally, small companies rely on limited product
lines and markets, financial resources, or other factors, and this may make them
more susceptible to setbacks or economic downturns. Small capitalized companies
may be more volatile in price, normally have fewer shares outstanding and trade
less frequently than large companies. Therefore, the securities of smaller
companies may be subject to wider price fluctuations. In many instances, the
securities of smaller companies are traded over the counter and may not be
traded in the volume typical of a national securities exchange.

      Risks of Stock Index Futures. Participation in the options or futures
markets involves investment risks and transaction costs to which the Small-Cap
Series would not be subject absent the use of these strategies. If the Series
management's prediction of movement in the direction of the securities markets
is inaccurate, the adverse consequences to the Series may leave it in a worse
position than if such strategies were not used. Risks inherent in the use of
options and stock index futures include (1) dependence on management's ability
to predict correctly movements in the direction of specific securities being
hedged or the movement in stock indices; (2) imperfect correlation between the
price of options and stock index futures and options thereon and movements in
the prices of the securities being hedged; (3) the fact that skills needed to
use these strategies are different from those needed to select portfolio
securities; (4) the possible absence of a liquid secondary market for any
particular instrument at any time; (5) the possible need to defer closing out
certain hedged positions to avoid adverse tax consequences; and (6) daily limits
on price variance for a futures contract or related options imposed by certain
futures exchanges and boards of trade may restrict transactions in such
securities on a particular day. See "Investment Policies" and "Taxes" in the
Statement of Additional Information.

The International Series. Portfolio investments for the International Series
will be made in equity securities of companies domiciled in developed countries,
but investments also may be made in the securities of companies domiciled in
developing countries. Equity securities include common and preferred stocks,
convertible securities, and rights and warrants to purchase common stocks. Under
normal circumstances, at least 80% of the total assets of the Series will be
invested in such equity securities of companies which are domiciled in at least
three different countries outside the United States. The Series currently
intends to diversify investments among countries to reduce currency risk.
Although the Series will typically hold a number of diversified securities, it
does entail above-average investment risk in comparison to the U.S. stock
market.

      Although the International Series intends to invest primarily in equity
securities of companies with market cap-


8
<PAGE>

italization of less than $1 billion listed on stock exchanges, it also may
invest in equity securities of such companies traded in over-the-counter
markets, as well as large and middle capitalization securities. Small
capitalization securities involve greater risk and the markets for such
securities may be more volatile and less liquid than those of larger securities.
Securities of companies in developing countries may pose liquidity risks. For a
description of special considerations and certain risks associated with
investments in foreign issuers, see "Risk Factors" below. The Series may
temporarily reduce its equity holdings for defensive purposes in response to
adverse market conditions and invest in domestic, Eurodollar and foreign
short-term money market instruments. See "Investment Objectives and Policies" in
the Statement of Additional Information.

      Although the International Series will not invest for short-term trading
purposes, investment securities may be sold from time to time without regard to
the length of time they have been held.

      Any remaining assets of the International Series not invested as described
above may be invested in certain securities or obligations as set forth in
"Other Policies" below.

      Foreign Currency Hedging Techniques. The International Series may utilize
various foreign currency hedging techniques described below when Fund management
believes the the currency of a particular foreign country may suffer a decline
against the U.S. dollar.

      A forward foreign currency contract involves an obligation to purchase or
sell a specific amount of a currency at a set price on a future date. The Series
may enter into forward foreign currency contracts (but not in excess of the
amount the Series has invested in non-U.S. dollar-denominated securities at the
time any such contract is entered into) in primarily two circumstances. First,
when the Series enters into a contract for the purchase or sale of a security
denominated in a foreign currency, the Series may desire to "lock in" the U.S.
dollar price of the security. By entering into a forward contract for the
purchase or sale of the amount of foreign currency involved in the underlying
security transaction, the Series will be able to protect against a possible loss
resulting from an adverse change in the relationship between the U.S. dollar and
the subject foreign currency during the period between the date of purchase or
sale and the date of settlement.

      Second, the International Series may enter into a forward contract to sell
the amount of foreign currency approximating the value of some or all of the
Series' portfolio securities denominated in such foreign currency or, in the
alternative, the Series may use a cross-currency-hedging technique whereby it
enters into such a forward contract to sell another currency (obtained in
exchange for the currency in which the portfolio securities are denominated if
such securities are sold) which it expects to decline in a similar manner.
Precise matching of the forward contract and the value of the securities
involved will generally not be possible since the future value of such
securities denominated in foreign currencies will change as a consequence of
market movements in the value of those securities between the date the forward
contract is entered into and the date the contract matures. The Series intends
to enter into such forward contracts under this second circumstance
periodically.

      The International Series also may transact currency put and call options
on U.S. exchanges or U.S. over-the-counter markets ("OTC") to protect the dollar
against foreign currency exposure. A put option gives the Series, upon payment
of a premium, the right to sell a currency at the exercise price until the
expiration of the option and serves to insure against adverse currency price
movements in the underlying portfolio assets denominated in that currency. The
premiums paid for such currency put and call options will not exceed 5% of the
net assets of the Series.

      Exchange-listed options markets in the United States include several major
currencies, and trading may be thin and illiquid. A number of major investment
firms and banks trade options which are more flexible than exchange-listed
options with respect to strike price and maturity date. These OTC options
generally are available on a wider range of currencies. OTC foreign-currency
options generally are more liquid than listed options and involve the credit
risk associated with the individual issuer. OTC options together with illiquid
securities may comprise no more than 15% of the Series' net assets.

      A currency call option, upon payment of a premium, gives the purchaser of
the option the right to buy and the seller (writer) of the obligation to sell,
the underlying currency at the exercise price until the expiration of the
option. The Series' purchase of a call option on a currency might be intended to
protect the Series against an increase in the price of the underlying currency
that it


                                                                               9

intends to purchase in the future by fixing the price at which it may purchase
such currency. The Series may sell (write) a call option on a foreign currency
only in conjunction with a purchase of a put option on that currency. Such a
strategy is designed to reduce the cost of a downside currency protection by
limiting currency appreciation potential. The face value of such writing (as
well as the corss-hedging described above) may not exceed 90% of the value of
the securities denominated in such currency (a) invested in by the Series to
cover such call writing or (b) to be crossed.

      Limitations imposed by the Internal Revenue Code on regulated investment
companies may restrict the Series' ability to engage in transactions in options,
forward contracts and cross hedges.

      The International Series' will segregate cash or permitted liquid
securities belonging to the Series in an amount not less than that required by
SEC Release 1066 and SEC staff interpretations thereof with respect to the
Series' assets committed to (a) currency put and call options, (b) forward
foreign currency contracts and (c) cross hedges entered into by the Series. If
the value of the securities segregated declines, additional cash or permitted
securities will be added on a daily basis (i.e., marked to market), so that the
segregated amount will not be less than the amount of the Series' commitments
with respect to such written options, forward foreign currency contracts and
cross hedges.

      Financial Futures and Options Thereon. The International Series may deal
in financial futures transactions with respect to the type of securities
described in this Prospectus, including indices of such securities and options
on such financial futures and indices. The Series will not enter into any
futures contracts, or options thereon, if the aggregate market value of the
securities covered by futures contracts plus options on such financial futures
exceeds 50% of the Series' total assets.

      Investment Funds. Some emerging countries have laws and regulations that
currently preclude direct foreign investment in the securities of their
companies. However, indirect foreign investment in the securities of such
countries is permitted through investment funds which have been specifically
authorized. The Series may invest (normally not more than 5% of the Series'
total assets) in these investment funds subject to the provisions of the
Investment Company Act of 1940, as amended, and other applicable restrictions as
discussed herein or in the Statement of Additional Information. If the Series
invests in such investment funds, the Series' shareholders will bear not only
their proportionate share of the expenses of the Series (including operating
expenses and the fees of Lord Abbett), but also will indirectly bear similar
expenses of the underlying investment funds.

      Depository Receipts. The International Series may invest in American
Depository Receipts ("ADRs"), Global Depository Receipts ("GDRs"), European
Depository Receipts ("EDRs") and other Depository Receipts (which, together with
ADRs, GDRs and EDRs, are hereinafter collectively referred to as "Depository
Receipts"), to the extent that such Depository Receipts become available. ADRs
are securities, typically issued by a U.S. financial institution (a
"depository"), that evidence ownership interests in a security or a pool of
securities issued by a foreign issuer (the "underlying issuer") and deposited
with the depository. ADRs may be established by a depository without
participation by the underlying issuer. GDRs, EDRs and other types of Depository
Receipts are typically issued by foreign depositories, although they may also be
issued by U.S. depositories, and evidence ownership interests in a security or
pool of securities issued by either a foreign or a U.S. corporation. Generally,
Depository Receipts in registered form are designed for use in the U.S.
securities market and Depository Receipts in bearer form are designed for use in
securities markets outside the United States. The Series may invest in sponsored
and unsponsored Depository Receipts. For purposes of the Series' investment
policies, the Series' investments in Depository Receipts will be deemed to be
investments in the underlying securities.

      When-Issued or Delayed Delivery Securities. The International Series may
purchase securities on a when-issued basis and, while awaiting delivery and
before paying for them ("settlement"), normally may invest in short-term
securities. The Series does not start earning interest on these when-issued
securities until settlement and often they are sold prior to settlement. During
the period between purchase and settlement, the value of the securities will
fluctuate and assets consisting of cash and/or marketable securities marked to
market daily in an amount sufficient to make payment at settlement will be
segregated at our custodian in order to pay for the commitment. There is a risk
that market yields available at settlement may be higher than yields obtained on
the purchase date, which could result in depreciation of value.

      While this investment strategy may contribute signifi-


10
<PAGE>

cantly to a portfolio turnover rate substantially in excess of 100%, it is
anticipated to have little or no transaction costs or adverse tax consequences
for the Series. Transaction costs normally do not include brokerage because the
Series' fixed-income portfolio transactions usually are on a principal basis
and, at the time of purchase, the Series normally anticipates that any markups
charged will be more than offset by the anticipated economic benefits of the
transactions. In the remote situation where this anticipated result does not
occur, the markups may offset any benefits.

      Covered Call Options. The International Series may write call options on
securities it owns, provided that the securities we hold to cover such options
do not represent more than 5% of the Series' net assets. A call option on stock
gives the purchaser of the option, upon payment of a premium to the writer of
the option, the right to call upon the writer to deliver a specified number of
shares of a stock on or before a fixed date at a predetermined price.

      Rights and Warrants. The International Series may invest in rights and
warrants to purchase securities provided that, at the time of the acquisition,
its investment in warrants, valued at the lower of cost or market, would not
exceed 5% of the Series' total assets. Warrants which are not listed on the New
York or American Stock Exchange or a major foreign exchange may not exceed 2% of
the Series' total assets.

      Repurchase Agreements. The International Series may enter into repurchase
agreements with respect to a security. A repurchase agreement is a transaction
by which the Series acquires a security and simultaneously commits to resell
that security to the seller (a bank or securities dealer) at an agreed-upon
price on an agreed-upon date. Such repurchase agreement must, at all times, be
collateralized by cash or U.S. Government securities having a value equal to, or
in excess of, the value of the repurchase agreement.

      Closed-end Investment Companies. The International Series may invest in
shares of closed-end investment companies if bought in the primary or secondary
market with a fee or commission no greater than the customary broker's
commission. Shares of such investment companies sometimes trade at a discount or
premium in relation to their net asset value and there may be duplication of
fees, for example, to the extent that the Series and the closed-end investment
company both charge a management fee.

      Lending of Portfolio Securities. The International Series may seek to earn
income by lending its portfolio securities if the loan is collateralized and its
terms are in accordance with regulatory requirements. These loans may not exceed
30% of the value of the Series' total assets. In such an arrangement, the Series
loans securities from its portfolio to registered broker-dealers. Such loans are
continuously collateralized by an amount at least equal to 100% of the market
value of the securities loaned. Cash collateral is invested in obligations
issues or guaranteed by the U.S. Government or its agencies, commercial paper or
bond obligations rated AA or A-1/P-1 by Standard & Poor's Rating Services
("S&P") or Moody's Investors Services, Inc. ("Moody's"), respectively, or
repurchase agreements with respect to the foregoing. As with other extensions of
credit, there are risks of delay in recovery and market loss should the
borrowers of the portfolio securities fail financially.

The Bond-Debenture Fund. Normally, we invest in lower-rated debt securities,
which entail greater risks than investments in higher-rated debt securities. The
former are referred to colloquially as "junk bonds." We believe that a high
total return (current income and capital appreciation) may be derived from an
actively-managed, diversified security portfolio. Under normal circumstances, we
invest at least 65% of our total assets in bonds and/or debentures. We seek
unusual values, particularly in lower-rated debt securities, some of which are
convertible into common stocks or have warrants to purchase common stocks.

      Higher yield on debt securities can occur during periods of inflation when
the demand for borrowed funds is high. Also, buying lower-rated bonds when the
credit risk is above average but, we think, likely to decrease, can generate
higher yields. Such debt securities normally will consist of secured debt
obligations of the issuer (i.e., bonds), general unsecured debt obligations of
the issuer (i.e., debentures) and debt securities which are subordinate in right
of payment to other debt of the issuer.

      In no event will we invest more than 10% of our gross assets at the time
of investment in debt securities which are in default as to interest or
principal.

      Normally the Bond-Debenture Fund invests in long-term debt securities when
we believe that interest rates in the long run will decline and prices of such
securities generally will be higher. When we believe that long-term interest
rates will rise, we will endeavor to shift our portfolio into shorter-term debt
securities whose prices might


                                                                              11
<PAGE>

not be affected as much by an increase in interest rates.

      The following policies are subject to change by the Board of Directors
without shareholder approval: (a) we must keep at least 20% of the value of our
total assets in (1) debt securities which, at the time of purchase, are
"investment grade," i.e., rated within one of the four highest grades determined
either by Moody's Investors Service, Inc. or Standard & Poor's Ratings Services,
(2) debt securities issued or guaranteed by the U.S. Government or its agencies
or instrumentalities, or (3) cash or cash equivalents (short-term obligations of
banks, corporations or the U.S. Government); (b) we may invest up to 20% of our
gross assets, at market value, in debt securities primarily traded in foreign
countries -- such foreign debt securities normally will be limited to issues
where there does not appear to be substantial risk of nationalization, exchange
controls, confiscation or other government restrictions; (c) subject to the
percentage limitations for purchases of other than debt securities described
below, we may purchase common and preferred stocks; (d) we may hold or sell any
property or securities which we may obtain through the exercise of conversion
rights or warrants or as a result of any reorganization, recapitalization or
liquidation proceedings for any issuer of securities owned by us. In no event
will we voluntarily purchase any securities other than debt securities, if, at
the time of such purchase or acquisition, the value of the property and
securities, other than debt securities, in our portfolio is greater than 35% of
the value of our gross assets. A purchase or acquisition will not be considered
"voluntary" if made in order to avoid loss in value of a conversion or other
premium; and (e) we neither purchase securities for short-term trading, nor for
the purpose of exercising control of management.

      We may, but have no present intention to, invest in financial futures and
options on financial futures and commit more than 5% of our gross assets to the
lending of our portfolio securities.

Risk Factors.

High Yield Debt Securities. The Bond-Debenture Fund may invest substantially in
lower-rated bonds because they tend to have higher yields. In general, the
market for lower-rated bonds is more limited than that for higher-rated bonds
and, therefore, may be less liquid. Market prices of lower-rated bonds may
fluctuate more than those of higher-rated bonds, particularly in times of
economic change and stress. In addition, because the market for lower-rated
corporate debt securities has in past years experienced wide fluctuations in the
values of certain of these securities, past experience may not provide an
accurate indication of the future performance of that market or of the frequency
of default, especially during periods of recession. Objective pricing data for
lower-rated bonds may be more limited than for higher-rated bonds and valuation
of such securities may be more difficult and require greater reliance upon
judgment.

      While the market for lower-rated bonds may be relatively insensitive to
interest rate changes, the market prices of these bonds structured as zero
coupon or pay-in-kind securities may be affected to a greater extent by such
changes and thus may be more volatile than prices of lower-rated securities
paying interest periodically in cash. Lower-rated bonds that are callable prior
to maturity may be more susceptible to refunding during periods of falling
interest rates, requiring replacement with lower-yielding securities.

      Since the risk of default generally is higher among lower-rated bonds, the
research and analysis performed by Lord, Abbett &Co. ("Lord Abbett") are
especially important in the selection of such bonds. If bonds are rated BB/Ba or
lower, they are described as "high-yield bonds" because of their generally
higher yields and are referred to colloquially as "junk bonds" because of their
greater risks. In selecting lower-rated bonds for investment, Lord Abbett does
not rely upon ratings, which evaluate only the safety of principal and interest,
not market value risk, and which, furthermore, may not accurately reflect an
issuer's current financial condition. We do not have any minimum rating criteria
for our investments in bonds. Some issuers may default as to principal and/or
interest payments subsequent to our purchase of their securities. Through
portfolio diversification, good credit analysis and attention to current
developments and trends in interest rates and economic conditions, investment
risk can be reduced, although there is no assurance that losses will not occur.

      Laws enacted from time to time could limit the tax or other advantages of,
and the issuance of, lower-rated securities and could adversely affect their
secondary market and the financial condition of their issuers. On the other
hand, such legislation (curtailing the supply of new issues) could improve the
liquidity, market values and demand for outstanding issues.

      During our past fiscal year, the percentages of our average net assets
invested in (a) rated bonds and (b) unrated bonds judged by us to be of a
quality compara-


12
<PAGE>

ble to rated bonds, on a dollar-weighted basis, calculated monthly were as
follows: 17.36% AAA/Aaa; 2.76% AA/Aa; 4.41% A/A; 6.19% BBB/Baa; 13.65% BB/Ba;
49.04% B/B; 1.18% CCC/Caa; 0.08% D; and 5.36% unrated.

Other Policies Common To Each Fund.

      Illiquid Securities -- Each Fund may invest up to 15% of its net assets in
illiquid securities. Bonds which are subject to legal or contractual
restrictions on resale, but which have been determined by the Board of Trustees
to be liquid, will not be subject to this limit. Investment by a Fund in such
securities, initially determined to be liquid, could have the effect of
diminishing the level of a Fund's liquidity during periods of decreased market
interest in such securities.

      Borrowing. Each Fund may borrow from banks (as defined in the Investment
Company Act of 1940, as amended the "Act"), in amounts up to 33 1/3% of its
total assets (including the amount borrowed). Each Fund may borrow up to an
additional 5% of its total assets for temporary purposes. The Funds may obtain
such short-term credit as may be necessary for the clearance of purchases and
sales of portfolio securities.

      Diversification. Each Fund intends to meet the diversification rules under
Subchapter M of the Internal Revenue Code. Generally, this requires, at the end
of each quarter of the taxable year, that (a) not more than 25% of a Fund's
total assets be invested in any one issuer and (b) with respect to 50% of a
Funds' total assets, no more than 5% of such total assets be invested in any one
issuer except U.S. Government securities.

      Each Fund, as a "diversified" investment company, is prohibited, with
respect to 75% of the value of its total assets, from investing more than 5% of
its total assets in securities of any one issuer other than U.S. Government
securities. For diversification purposes, the identification of an "issuer" for
the fixed-income portion of a Funds' assets will be determined on the basis of
the source of assets and revenues committed to meeting interest and principal
payments of the securities. When the assets and revenues of a sovereign state's
political subdivision are separate from those of the sovereign state government
creating the subdivision, and the security is backed only by the assets and
revenues of the subdivision, then the subdivision would be considered the sole
issuer. Similarly, if a revenue bond is backed only by the assets and revenues
of a nongovernmental user, then such user would be considered the sole issuer.

      Securities Lending. Each Fund may lend securities to financial
institutions which provide continuous collateral equal to the market value of
the securities loaned. Some risk may involve delay in recovery of collateral and
loss should the borrower of the security fail financially. Loans, in the
aggregate, may not exceed 30% of the Fund's total assets.

      Covered Call Options. A covered call option on stock gives the buyer of
the option, upon payment of a premium to the seller (writer) of the option, the
right to call upon the writer to deliver a specified number of shares of a stock
owned by the writer on or before a fixed date at a predetermined price.

      Although a Fund receives income based on receipt of the premium, it gives
up participation in the appreciation of the stock above the predetermined price
if it is called away by the buyer. A Fund may write covered call options on
securities having an aggregate market value not to exceed 20% of the Fund's
gross assets.

Risk Factors Common To Each Fund.

      Foreign Securities -- Securities markets of foreign countries in which
each Fund may invest generally are not subject to the same degree of regulation
as the U.S. markets and may be more volatile and less liquid than the major U.S.
markets. Lack of liquidity may affect a Fund's ability to purchase or sell large
blocks of securities and thus obtain the best price. There may be less
publicly-available information on publicly-traded companies, banks and
governments in foreign countries than is generally the case for such entities in
the United States. The lack of uniform accounting standards and practices among
countries impairs the validity of direct comparisons of valuation measures (such
as price/earnings ratios) for securities in different countries. In addition a
change in the value of any foreign currency relative to the U.S. dollar will
result in a corresponding change in the U.S. dollar value of the Fund's assets
denominated or traded in that currency. A Fund may incur costs associated with
currency hedging and the conversion of foreign currency into U.S. dollars and
may be adversely affected by restrictions on the conversion or transfer of
foreign currency. Other considerations include political and social instability,
expropriation, higher transaction costs and different securities settlement
practices. Settlement periods for foreign securities, which are sometimes longer
than those for securities of U.S. issuers,


                                                                              13
<PAGE>

may affect portfolio liquidity. These different settlement practices may cause
missed purchasing opportunities and/or the loss of interest on money market and
debt investments pending further equity or long-term debt investments. In
addition, foreign securities held by a Fund may be traded on days that it does
not value the portfolio securities, such as Saturdays and customary U.S.
business holidays, and, accordingly, a Fund's net asset value may be
significantly affected on days when shareholders do not have access to the Fund.
Many of the emerging or developing countries may have higher and more rapidly
fluctuating inflation rates, a higher demand for capital investment, a higher
dependence on export markets for their major industries, and a greater need to
develop basic economic infrastructures than more developed countries. Also, it
may be more difficult to obtain a judgment in a court outside the United States.

Change of Investment Objectives and Policies. The Funds will not change their
investment objectives without shareholder approval. If any Fund determines that
its objective can best be achieved by a change in investment policy or strategy,
a Fund may make such change without shareholder approval by disclosing it in the
prospectus.

5 PURCHASES
  ==============================================================================

Class Y shares. Class Y shares are purchased at net asset value with no sales
charge of any kind. The net asset value of our shares is calculated every
business day as of the close of the New York Stock Exchange ("NYSE") by dividing
net assets by the number of shares outstanding. Securities are valued at their
market value as more fully described in the Statement of Additional Information.

Who May Invest? Eligible purchasers of Class Y shares include (i) certain
authorized brokers, dealers, registered investment advisers or other financial
institutions who have entered into an agreement with Lord Abbett Distributor in
accordance with certain standards approved by Lord Abbett Distributor, providing
specifically for the use of our Class Y shares in particular investment products
made available for a fee to clients of such brokers, dealers, registered
investment advisers or other financial institutions ("mutual fund wrap fee
programs"), (ii) the trustee or custodian under any deferred compensation or
pension or profit-sharing plan or payroll deduction IRA established for the
benefit of the employees of any company with an account(s) in excess of $10
million managed by Lord Abbett or its sub-advisors on a private-advisory-account
basis, and (iii) institutional investors, including retirement plans, companies,
foundations, trusts, endowments and other entities where the total amount of
potential investable assets exceeds $50 million that were not introduced to Lord
Abbett by persons associated with a broker or dealer primarily involved in the
retail security business. Additional payments may be made by Lord Abbett out of
its own resources with respect to certain of these sales.

How Much Must You Invest? You may buy our shares through any independent
securities dealer having a sales agreement with Lord Abbett Distributor, our
exclusive selling agent. Place your order with your investment dealer or send it
to the Lord Abbett Fund you selected (P.O. Box 419100, Kansas City, Missouri
64141). The minimum initial investment is $1 million except for mutual fund wrap
fee programs which have no minimum. This offering may be suspended, changed or
withdrawn by Lord Abbett Distributor which reserves the right to reject any
order.

Buying Shares Through Your Dealer. Orders for shares received by the Fund prior
to the close of the NYSE, or received by dealers prior to such close and
received by Lord Abbett Distributor prior to the close of its business day, will
be confirmed at net asset value effective at such NYSE close. Orders received by
dealers after the NYSE closes and received by Lord Abbett Distributor in proper
form prior to the close of its next business day are executed at the net asset
value effective as of the close of the NYSE on that next business day. The
dealer is responsible for the timely transmission of orders to Lord Abbett
Distributor. A business day is a day on which the NYSE is open for trading.

Buying Shares By Wire. To open an account, call 800 -426-1129 to set up your
account and to arrange a wire transaction. Wire to: United Missouri Bank of
Kansas City, N.A., Routing number - 101000695, bank account number: 9878002611,

of the fund/series of your choice, note Class Y shares and include your account
number and your name.

6 SHAREHOLDER SERVICES
  ==============================================================================

We offer the following shareholder services:

      Telephone Exchange Privilege: Class Y shares may be exchanged without a
service charge for shares of the same class of any other Lord Abbett-sponsored
fund.

      You or your investment professional with proper identification can
instruct your Fund to exchange uncertificated shares of a class (held by the
transfer agent) by telephone. Shareholders have this privilege unless they
refuse it in writing. A Fund will not be liable for following instructions
communicated by telephone that it reasonably believes to be genuine and will
employ reasonable procedures to confirm that instructions received are genuine,
including requesting proper identification and recording all telephone
exchanges. Instructions must be received by a Fund in Kansas City (800-821-5129)
prior to the close of the NYSE to obtain a Fund's net asset value per class
share on that day. Expedited exchanges by telephone may be difficult to
implement in times of drastic economic or market change. The exchange privilege
should not be used to take advantage of short-term swings in the market. Each
Fund reserves the right to terminate or limit the privilege of any shareholder
who makes frequent exchanges. Each Fund can revoke the privilege for all
shareholders upon 60 days' prior written notice. A prospectus for the other Lord
Abbett-sponsored fund selected by you should be obtained and read before an
exchange. Exercise of the Exchange Privilege will be treated as a sale for
federal income tax purposes and, depending on the circumstances, a capital gain
or loss may be recognized.

      All correspondence should be directed to the Fund you selected (P.O. Box
419100, Kansas City, Missouri 64141; 800-821-5129).

7 OUR MANAGEMENT
  ==============================================================================

Our business is managed by our officers on a day-to-day basis under the overall
direction of our Board of Directors/Trustees with the advice of Lord, Abbett &
Co. ("Lord Abbett") ("Fund Management"). Each Fund employs Lord Abbett as
investment manager pursuant to a Management Agreement. Lord Abbett has been an
investment manager for over 69 years and currently manages approximately $27
billion in a family of mutual funds and other advisory accounts. Under the
Management Agreement, Lord Abbett provides us with investment management
services and personnel, pays the remuneration of our officers and of our
Directors/Trustees affiliated with Lord Abbett, provides us with office space
and pays for ordinary and necessary office and clerical expenses relating to
research, statistical work and supervision of our portfolios and certain other
costs. Lord Abbett provides similar services to nine other Lord Abbett-sponsored
funds having various investment objectives and also advises other investment
clients.

      W. Thomas Hudson, Jr., Partner of Lord Abbett and Executive Vice President
and portfolio manager of Affiliated Fund, is primarily responsible for the
day-to-day management of the Fund. Mr. Hudson has been with Lord Abbett since
1982 and has over 32 years of investment experience. Mr. Hudson is assisted by,
and may delegate management duties to, other Lord Abbett employees who may be
Fund officers.

      Robert P. Fetch has been primarily responsible for the day-to-day
management of the Small-Cap Series since inception and is assisted by Gregory M.
Macosko. Prior to joining Lord Abbett, Mr. Fetch was a Managing Director of
Prudential Investment Advisors.

      Christopher J. Towle, Executive Vice President and portfolio manager of
the Fund, is primarily responsible for the day-to-day management of the Fund.
Mr. Towle has been with Lord Abbett since 1988 and has over 17 years of
investment experience. Mr. Towle is assisted by, and may delegate management
duties to, other Lord Abbett employees who may be Fund officers.

      Christopher Taylor serves as portfolio manager of the International
Series. Mr. Taylor is Deputy Managing Director of Fuji Investment Management Co.
(Europe), Ltd. (the "Sub-Adviser"). He has been with the Sub-Adviser and its
predecessor since 1987 and has sixteen years of investment experience.

      Lord Abbett Securities Trust has entered into an agreement with the
Sub-Adviser, under which the Sub-Adviser provides Lord Abbett with advice with
respect to the International Series' assets. The Sub-Adviser is controlled by
Fuji Investment Management Co. (Tokyo). Fuji Bank Limited of Tokyo, Japan ("Fuji
Bank") directly owns 40% of the outstanding voting stock of the Sub-Adviser.
Fuji Investment Management Co. (Tokyo) is an affiliate


                                                                              15
<PAGE>

of Fuji Bank. Lord Abbett indirectly owns a minor percentage of such outstanding
voting stock. As of March 31, 1998, the Sub-Adviser managed approximately $700
million, which is invested globally. The Sub-Adviser furnishes Lord Abbett with
advice and recommendations with respect to the International Series' assets,
including advice about the allocation of investments among foreign securities
markets and foreign equity and debt securities markets and foreign equity and
debt securities and, subject to consultation with Lord Abbett, advice as to cash
holdings and what securities in the portfolio should be purchased, held or
disposed of. The Sub-Adviser also gives advice with respect to foreign currency
matters.

      Although, under normal circumstances, the International Series will be
invested at least 80% in equity securities of non-U.S. issuers, subject to the
direction of the Board of Trustees, Lord Abbett, in consultation with the
Sub-Adviser, will determine at least quarterly, and more frequently as Lord
Abbett determines, the percentage of assets of the International Series that
shall be allocated (the "Asset Allocation") for investment in the United States
and in foreign markets, respectively.

      Each Fund pays Lord Abbett a monthly fee based on average daily net assets
for each month. In addition, each Fund pays all expenses not expressly assumed
by Lord Abbett. For the fiscal year ended October 31, 1997, the fee paid by
Affiliated Fund to Lord Abbett as a percentage of average daily net assets was
at the annual rate of 0.32 of 1%. For the fiscal year ended December 31, 1997,
the fee paid by Bond-Debenture Fund to Lord Abbett as a percentage of average
daily net assets was at the annual rate of 0.46 of 1%. The Small-Cap Series, for
the fiscal year ended November 30, 1997, paid Lord Abbett as a percentage of
average daily net assets based on average daily net assets for each month at the
annual rate of 0.75 of 1% for the Small-Cap Series. This fee may be higher than
that paid by other mutual funds. The International Series for the fiscal year
ended October 31, 1997 paid Lord Abbett as a percentage of average daily net
assets at the annual rate of 0.75 of 1% for the International Series. Lord
Abbett, when not waiving its management fee, is obligated to pay the Sub-Adviser
a monthly fee equal to one-half of Lord Abbett's fee as described above.
Regardless of such waiver, Lord Abbett is free to pay the Sub-Adviser. 

      The Funds will not hold annual meetings of shareholders unless required to
by the Investment Company Act of 1940, the Board of Directors/Trustees or the
shareholders with one-quarter of the outstanding stock of each Fund entitled to
vote. See the Statement of Additional Information for each Fund for more
details.

The Funds and Their Shares.

Each Fund is a diversified open-end management investment company. Lord Abbett
Affiliated Fund, Inc., was incorporated under Maryland law on November 26, 1975;
Lord Abbett Research Fund was incorporated under Maryland law on April 6, 1992;
Lord Abbett Securities Trust was organized as a Delaware business trust on
February 26, 1993 and Lord Abbett Bond-Debenture Fund, Inc. was incorporated
under Maryland law on January 23, 1976.

      Each Fund's Classes of shares have equal rights as to voting, dividends
and distributions, except for differences resulting from certain class-specific
expenses. Class Y shares are sold to institutions exclusively with no front-end
or contingent deferred sales charge and no Rule 12b-1 charges. Class A, B, C and
P shares are sold to the retail public and are subject to Rule 12b-1 charges.
With certain exceptions, Class A shares are sold with a front-end sales charge
at the time of purchase and are not subject to a contingent deferred sales
charge when they are redeemed. Class B shares are sold without a sales charge at
the time of purchase, but are subject to a contingent deferred sales charge if
they are redeemed before the sixth anniversary of purchase. Class B shares will
automatically convert to Class A shares on the eighth anniversary of purchase.
Class C shares are sold with no front-end sales charge but have no conversion
feature and are subject to a 1% contingent deferred sales charge on redemptions
before the first anniversary of purchase. Class P shares are sold with no
front-end sales charge exclusively to pension plans and have neither a
conversion feature nor a contingent deferred sales charge. Due to the
class-specific expenses, dividends of Class B, C and P shares are likely to be
lower than for Class A shares, and are likely to be higher for Class Y shares
than for any other Class of shares. For more information regarding the Class A,
B, C and P shares, please call 800-874-3733 to request a different prospectus.
There is a possibility that one fund might become liable for any misstatement,
inaccuracy, or incomplete disclosure in the prospectus concerning the other
fund.

8 DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES
  ==============================================================================

Dividends from net investment income are paid annually to shareholders of the
Small-Cap and International Series. Supplemental dividends may be paid in
December or January to International Series shareholders. Affiliated Fund
shareholders are paid dividends in February, May, August and November. A
supplemental dividend may also be paid in December. Bond-Debenture Fund
shareholders are paid dividends monthly.

      Any capital gains distribution may be taken in cash or reinvested.
Distributions by a Fund of any net long-term capital gains will be taxable to a
shareholder as long-term capital gains regardless of how long the shareholder
has held the shares. Under recently enacted legislation, the maximum tax rate on
long-term capital gains for a U.S. individual, estate or trust is reduced to 20%
for distributions derived from the sale of assets held by a Fund for more than
18 months. (If the taxpayer is in the 15% tax bracket, the rate is 10%) For
distributions derived from the sale of assets held by a Fund between 12 and 18
months, the tax rate remains at 28% (15% if the taxpayer is in the 15% tax
bracket).

      If you elect to receive dividends or capital gains in cash, a check will
be mailed to you as soon as possible after the reinvestment date. If you arrange
for direct deposit, your payment will be electronically transmitted to your bank
account within one day after the payable date. Most investors reinvest their
dividends and capital gains. If you choose this option, or if you do not
indicate any choice, your dividends and capital gains distributions will be
automatically reinvested in additional shares.

      A Fund pays no federal income tax on the earnings it distributes to
shareholders. Consequently, dividends you receive from a Fund, whether
reinvested or taken in cash, are generally considered taxable. Dividends
declared in December of any year will be treated for federal income tax purposes
as having been received by shareholders in that year if they are paid before
February 1 of the following year.

      Each Fund may be subject to foreign withholding taxes which would reduce
the yield on their investments. Tax treaties between certain countries and the
United States may reduce or eliminate such taxes. See the Statement of
Additional Information for additional details.

      Shareholders may be subject to a $50 penalty under the Internal Revenue
Code and we may be required to withhold and remit to the U.S. Treasury a portion
(31%) of any redemption or repurchase proceeds (including the value of shares
exchanged into another Lord Abbett-sponsored fund) and of any taxable dividend
or distribution on any account where the payee failed to provide a correct
taxpayer identification number or to make certain required certifications.

      Each January the Fund will mail to you, if applicable, a Form 1099 tax
information statement detailing your dividends and capital gain distributions.
You should consult your tax adviser concerning applicable state and local taxes.

9 REDEMPTIONS
  ==============================================================================

To obtain the proceeds of an expedited redemption, you can telephone your Fund.
A Fund will not be liable for following instructions communicated by telephone
that it reasonably believes to be genuine and will employ reasonable procedures
to confirm that instructions received are genuine, including requesting proper
identification, recording all telephone redemptions and mailing the proceeds
only to the named shareholder at the address appearing on the account
registration.

      Send your written redemption request to the Fund you selected (P.O. Box
419100, Kansas City, Missouri 64141) with signature(s) and any legal capacity of
the signer(s) guaranteed by an eligible guarantor accompanied by any
certificates for shares to be redeemed and other required documentation. We will
make payment of the net asset value of the shares on the date the redemption
order was received in properform. Payment will be made within three business
days. Each Fund may suspend the right to redeem shares for not more than three
days (or longer under unusual circumstances as permitted by Federal law). If you
have purchased a Fund's shares by check and subsequently submit a redemption
request, redemption proceeds will be paid upon clearance of your purchase check,
which may take up to 15 days. To avoid delays you may arrange for the bank upon
which a check was drawn to communicate to the Fund that the check has cleared.

Wire. You must sign up for the wire feature before using it. To verify that it
is in place, call 800-426-1129. Minimum wire: $1,000. Your wire redemption
request must be received by your Fund before the close of the NYSE for money to
be wired on the next business day.

      Tax-qualified Plans: For redemptions of $50,000


                                                                              17
<PAGE>

or less, follow normal redemption procedures. Redemptions over $50,000 must be
in writing from the employer, broker or plan administrator stating the reason
for the redemption. The reason for the redemption must be received by the Fund
prior to, or concurrent with, the redemption request.

10 PERFORMANCE
   =============================================================================

      The Affiliated Fund, during the past fiscal year ending October 31, 1997,
enjoyed returns above historical averages due to an environment of solid
economic growth, low inflation and strong corporate profit gains. Throughout
most of the period, the portfolio has been evenly diversified, but with a
moderate overweighting in financial stocks. Furthermore, we have shifted our
focus within this group of stocks towards insurance companies, which are
benefiting from industry-wide consolidation and cost-cutting efforts.

      The Small-Cap Series completed its fiscal year on November 30, 1997. The
exceptional performance of the Series over the past fiscal year can be
attributed to select industrial and technology stocks in the portfolio. During
the year, valuations of small-cap stocks were favorable, providing many
opportunities in the marketplace to purchase companies with performance
characteristics that drive toward consistent, strong performance with low
volatility. We look for companies with long operating histories, strong market
positions withing their industry and financial strength. These characteristics
help to reduce business risk and protect companies form both economic and
competitive pressures. We continue to seek issues with solid fundamental
prospects in the small-cap universe to add value to the Series.

      The International Series completed its fiscal year on October 31, 1997. It
enjoyed a strong performance over the past year due in large part to gains made
by industrial companies which are domiciled in Germany and Canada. One company
that helped portfolio performance during the year manufactures "zero emission"
hydrogen powered fuel cells that produce water and oxygen as waste materials.
Another is the world's largest supplier of database software tools used for
information integration. These are some examples of what we believe are industry
leaders. In addition, due to our selective investment process, we had minimal
exposure to companies located in the emerging and Far Eastern markets that fell
sharply during the period.

      The Bond-Debenture Fund completed its fiscal year on December 31, 1997. It
posted strong performance amid the continuing economic growth, low inflation and
favorable interest-rate environment that characterized the period. Particularly
beneficial to its performance was the concentration in telephone communications,
media and energy sectors. Basic industry issues also generally outperformed the
bond market. In addition, the robust U.S. economic growth provided significant
increases in corporate profitability, which resulted in improved credit ratings
and strong gains for many of our holdings.

      Yield and Total Return. Yield and total return data may, from time to
time, be included in advertisements about each Fund. The Class Y share "yield"
is calculated by dividing the annualized net investment income per share on the
portfolio during a 30-day period by the net asset value on the last day of the
period. The yield data represents a hypothetical investment return on the
portfolio, and does not measure an investment return based on dividends actually
paid to shareholders. To show that return, a dividend distribution rate may be
calculated. The dividend distribution rate is calculated by dividing the
dividends of the Class Y derived from net investment income during a stated
period by the net asset value on the last day of the period. Yields and dividend
distribution rates for Class Y shares is shown at net asset value without the
deduction of any sales charge.

      "Total return" for the one-, five- and ten-month periods represents the
average annual compounded rate of return on an investment of $1,000 in a Fund at
the net asset value. When total return is quoted for Class Y shares, it is shown
at net asset value without the deduction of any sales charge. Quotations of
yield or total return for any period when an expense limitation is in effect
will be greater than if the limitation had not been in effect. See "Past
Performance" in the Statement of Additional Information for a more detailed
description.

      See "Past Performance" in the Statement of Additional Information for a
more detailed discussion concerning the computation of each Fund's total return
and yield.

Statement of Additional Information                                June 30, 1998

                      Lord Abbett Bond-Debenture Fund, Inc.

- --------------------------------------------------------------------------------
This Statement of Additional Information is not a Prospectus. A Prospectus for
the Class Y shares of Lord Abbett Affiliated Fund, Inc. ("Affiliated Fund"),
Lord Abbett Research Fund, Inc. - Small-Cap Series ("Small-Cap Series"), Lord
Abbett Securities Trust International Series ("International Series"), and Lord
Abbett Bond-Debenture Fund, Inc. ("Bond-Debenture Fund") (individually a "Fund"
and collectively the "Funds" or "We") may be obtained from your securities
dealer or from Lord Abbett Distributor LLC ("Lord Abbett Distributor") at The
General Motors Building, 767 Fifth Avenue, New York, New York 10153-0203. This
Statement relates to, and should be read in conjunction with, the Prospectus
dated June 30, 1998 (the "Prospectus").

Our Boards of Directors (Trustees) have authority to create and classify shares
in separate series, without further action by shareholders. To date, the Boards
of Directors (Trustees) have authorized four Classes of shares for each Fund (A,
B, C and Y), and Class P shares for Affiliated Fund and Bond-Debenture Fund. The
Board of a Fund will allocate a Fund's shares among its classes from time to
time. All shares of a Fund have equal noncumulative voting rights and equal
rights with respect to dividends, assets and liquidation, except for certain
class-specific expenses. They are fully paid and nonassessable when issued and
have no preemptive or conversion rights. Although no present plans exist to do
so, further series may be added to one or more of the Funds in the future. The
Investment Company Act of 1940, as amended (the "Act"), requires that where more
than one series exists for a Fund, each series must be preferred over all other
series in respect of assets specifically allocated to such series.

Rule 18f-2 under the Act provides that any matter required to be submitted, by
the provisions of the Act or applicable state law, or otherwise, to the holders
of the outstanding voting securities of an investment company such as a Fund
shall not be deemed to have been effectively acted upon unless approved by the
holders of a majority of the outstanding shares of each class or series affected
by such matter. Rule 18f-2 further provides that a class or series shall be
deemed to be affected by a matter unless the interests of each class or series
in the matter are substantially identical or the matter does not affect any
interest of such class or series. However, the Rule exempts the selection of
independent public accountants, the approval of principal distribution contracts
and the election of directors from the separate voting requirements of the Rule.

Shareholder inquiries should be made by writing directly to your Fund or by
calling 800-821-5129. In addition, you can make inquiries through Lord Abbett
Distributor.

                             1. Investment Policies

Fundamental Investment Restrictions

Each Fund is subject to the following investment restrictions which cannot be
changed without approval of the holders of a majority of a Fund's outstanding
shares. Each Fund may not: (1) borrow money, except that (i) each Fund may
borrow from banks (as defined in the Investment Company Act of 1940, as amended
(the "Act")) in amounts up to 33 1/3% of its total assets (including the amount
borrowed), (ii) each Fund may borrow up to an additional 5% of its total assets
for temporary purposes, (iii) each Fund may obtain such short-term credit as may
be necessary for the clearance of purchases and sales of portfolio securities
and (iv) each Fund may purchase securities on margin to the extent permitted by
applicable law; (2) pledge its assets (other than to secure borrowings, or to
the extent permitted by the Fund's investment policies as permitted by
applicable law); (3) engage in the underwriting of securities, except pursuant
to a merger or acquisition or to the extent that, in connection with the
disposition of its portfolio securities, it may be deemed to be an underwriter
under federal securities laws; (4) make loans to other persons, except that the
acquisition of bonds, debentures or other corporate debt securities and
investment in government obligations, commercial paper, pass-through
instruments, certificates of deposit, bankers acceptances, repurchase agreements
or any similar instruments shall not be subject to this limitation, and except
further that each Fund may lend its portfolio securities, provided that the
lending of portfolio securities may be made only in accordance with applicable
law; (5) buy or sell real estate (except that each Fund may invest in securities
directly or indirectly secured by real estate or interests therein or issued by
companies which invest in real estate or interests therein) or commodities or
commodity contracts (except to the extent each Fund may do so in accordance with
applicable law and without registering as a commodity pool operator under the
Commodity Exchange Act as, for example, with futures contracts); (6) with
respect to 75% of the gross assets of each Fund, buy securities of one issuer
representing more than (i) 5% of each Fund's gross assets, except securities
issued or guaranteed by the U.S. Government, its agencies or instrumentalities
or (ii) 10% of the voting securities of such issuer; (7) invest more than 25% of
its assets, taken at market value, in the securities of issuers in any
particular industry (excluding securities of the U.S. Government, its agencies
and instrumentalities); or (8) issue senior securities to the extent such
issuance would violate applicable law.

With respect to the restrictions mentioned herein, compliance therewith will not
be affected by changes in the market value of portfolio securities but will be
determined at the time of purchase or sale of such securities.

Non-Fundamental Investment Restrictions. In addition to the investment
restrictions above which cannot be changed without shareholder approval, each
Fund also is subject to the following non-fundamental investment policies which
may be changed by the Boards of Directors (Trustees) without shareholder
approval. Each Fund may not: (1) borrow in excess of 33 1/3% of its total assets
(including the amount borrowed), and then only as a temporary measure for
extraordinary or emergency purposes; (2) make short sales of securities or
maintain a short position except to the extent permitted by applicable law; (3)
invest knowingly more than 15% of its net assets (at the time of investment) in
illiquid securities, except for securities qualifying for resale under Rule 144A
of the Securities Act of 1933, deemed to be liquid by the Boards of Directors
(Trustees); (4) invest in the securities of other investment companies (in the
case of the International Series, as long as the series is an underlying fund in
a fund-of-funds structure) except as permitted by applicable law; (5) invest in
securities of issuers which, with their predecessors, have a record of less than
three years' continuous operations, if more than 5% of each Fund's total assets
would be invested in such securities (this restriction shall not apply to
mortgaged-backed securities, asset-backed securities or obligations issued or
guaranteed by the U. S. Government, its agencies or instrumentalities); (6) hold
securities of any issuer if more than 1/2 of 1% of the securities of such issuer
are owned beneficially by one or more officers or directors (trustees) of a Fund
or by one or more partners or members of the Fund's underwriter or investment
adviser if these owners in the aggregate own beneficially more than 5% of the
securities of such issuer; (7) invest in warrants if, at the time of the
acquisition, its investment in warrants, valued at the lower of cost or market,
would exceed 5% of each Fund's total assets (included within such limitation,
but not to exceed 2% of each Fund's total assets, are warrants which are not
listed on the New York or American Stock Exchange or a major foreign exchange);
(8) invest in real estate limited partnership interests or interests in oil, gas
or other mineral leases, or exploration or other development programs, except
that each Fund may invest in securities issued by companies that engage in oil,
gas or other mineral exploration or other development activities; (9) write,
purchase or sell puts, calls, straddles, spreads or combinations thereof, except
to the extent 


                                       2
<PAGE>

permitted in a Fund's prospectus and statement of additional information, as
they may be amended from time to time; (10) buy from or sell to any of a Fund's
officers, directors (trustees), employees, or its investment adviser or any of a
Fund's officers, directors (trustees), partners or employees, any securities
other than shares of a Fund; (11) with respect to Affiliated Fund, pledge,
mortgage or hypothecate its assets; however, this provision does not apply to
the grant of escrow receipts or the entry into other similar escrow arrangements
arising out of the writing of covered call options; or (12) with respect to
Bond-Debenture Fund, invest more than 10% of the market value of its gross
assets at the time of investment in debt securities which are in default as to
interest or principal.

For the year ended October 31, 1997, Affiliated Fund's portfolio turnover rate
was 46.41% versus 47.06% for the prior year. For the year ended November 30,
1997, the Small-Cap Series' portfolio turnover rate was 45.24% and 110.09% for
the period December 13, 1997 (commencement of operations) to November 30, 1997.
For the period December 13, 1996 (commencement of operations) to October 31,
1997, the International Series' portfolio turnover rate was 29.72%. For the year
ended December 31, 1997, Bond-Debenture Fund's portfolio turnover rate was
89.14% versus 106.79% for the prior year.

Covered Call Options (Affiliated Fund, International Series and Bond-Debenture
Fund).

As stated in the Prospectus, each Fund may write covered call options which are
traded on a national securities exchange with respect to securities in its
portfolio in an attempt to increase its income and to provide greater
flexibility in the disposition of its portfolio securities. A "call option" is a
contract sold for a price (the "premium"), giving its holder the right to buy a
specific number of shares of stock at a specific price prior to a specified
date. A "covered call option" is a call option issued on securities already
owned by the writer of the call option for delivery to the holder upon the
exercise of the option. During the period of the option, each Fund forgoes the
opportunity to profit from any increase in the market price of the underlying
security above the exercise price of the option (to the extent that the increase
exceeds its net premium). Each Fund may enter into "closing purchase
transactions" in order to terminate its obligation to deliver the underlying
security (this may result in a short-term gain or loss). A closing purchase
transaction is the purchase of a call option (at a cost which may be more or
less than the premium received for writing the original call option) on the same
security, with the same exercise price and call period as the option previously
written. If a Fund is unable to enter into a closing purchase transaction, it
may be required to hold a security that it might otherwise have sold to protect
against depreciation. Each Fund intends to write covered call options with
respect to securities with an aggregate market value of more than 10%
(Affiliated Fund), 5% (International Series), and 20% (Bond-Debenture Fund).
This percentage limitation will not be increased without prior disclosure in the
current Prospectus.

OTHER INVESTMENT POLICIES COMMON TO THE FUNDS (WHICH CAN BE CHANGED WITHOUT
SHAREHOLDER APPROVAL.)

Lending of Portfolio Securities (Affiliated Fund, Small-Cap Series,
International Series and Bond-Debenture Fund). Although the Funds have no
current intention of doing so, each may seek to earn income by lending portfolio
securities. Under present regulatory policies, such loans may be made to member
firms of the New York Stock Exchange ("NYSE") and are required to be secured
continuously by collateral consisting of cash, cash equivalents, or United
States Treasury bills maintained in an amount at least equal to the market value
of the securities loaned. Each will have the right to call a loan and obtain the
securities loaned at any time upon five days' notice. During the existence of a
loan a Fund will receive the income earned on investment of collateral. The
aggregate value of the securities loaned will not exceed 30% for the Affiliated
Fund, International Series and Bond-Debenture Fund, and 5% for the Small-Cap
Series of the value of a Fund's total assets.

By lending portfolio securities, each Fund can increase its income by continuing
to receive interest on the loaned securities as well as by either investing the
cash collateral in permissible investments, such as U.S. Government Securities,
or obtaining yield in the form of interest paid by the borrower when such U.S.
Government Securities are used as collateral. Each Fund will comply with the
following conditions whenever it loans securities: (i) each Fund must receive at
least 100% collateral from the borrower; (ii) the borrower must increase the
collateral whenever the market value of the securities loaned rises 


                                       3
<PAGE>

above the level of the collateral; (iii) each Fund must be able to terminate the
loan at any time; (iv) each Fund must receive reasonable compensation with
respect to the loan, as well as any dividends, interest or other distributions
on the loaned securities; (v) each Fund may pay only reasonable fees in
connection with the loan; and (vi) voting rights on the loaned securities may
pass to the borrower except that, if a material event adversely affecting the
investment in the loaned securities occurs, each Fund's Board of Directors
(Trustees) must terminate the loan and regain the right to vote the securities

Rule 144A Securities (Affiliated Fund, Small-Cap Series, International Series
and Bond-Debenture Fund). Each Fund may invest in securities qualifying for
resale to "qualified institutional buyers" under SEC Rule 144A that are
determined by the Board, or by Lord Abbett pursuant to the Board's delegation,
to be liquid securities. The Board will review quarterly the liquidity of the
investments each Fund makes in such securities. Investments by each Fund in Rule
144A securities initially determined to be liquid could have the effect of
diminishing the level of each Fund's liquidity during periods of decreased
market interest in such securities among qualified institutional buyers.

Each Fund's custodian will segregate cash or liquid high-grade debt securities
in an amount not less than that required by Securities Exchange Commission
("SEC") Release 10666 with respect to Fund assets committed to written covered
call options. If the value of the segregated securities declines, additional
cash or debt securities will be added on a daily basis (i.e., marked-to-market)
so that the segregated amount will not be less than the amount of each Fund's
commitments with respect to such written options.

OTHER INTERNATIONAL SERIES INVESTMENT POLICIES (WHICH CAN BE CHANGED WITHOUT

Financial Futures Contracts. The International Series may enter into contracts
for the future delivery of a financial instrument, such as a security or the
cash value of a securities index. This investment technique is designed
primarily to hedge (i.e., protect) against anticipated future changes in
interest rates or market conditions which otherwise might adversely affect the
value of securities which the International Series holds or intends to purchase.
A "sale" of a futures contract means the undertaking of a contractual obligation
to deliver the securities or the cash value of an index called for by the
contract at a specified price during a specified delivery period. A "purchase"
of a futures contract means the undertaking of a contractual obligation to
acquire the securities or cash value of an index at a specified price during a
specified delivery period. At the time of delivery pursuant to the contract,
adjustments are made to recognize differences in value arising from the delivery
of securities which differ from those specified in the contract. In some cases,
securities called for by a futures contract may not have been issued at the time
the contract was written. The International Series will not enter into any
futures contracts or options on futures contracts if the aggregate of the market
value of the securities covered by its outstanding futures contracts and
securities covered by futures contracts subject to the outstanding options
written by it would exceed 50% of its total assets.

Although some financial futures contracts by their terms call for the actual
delivery or acquisition of securities, in most cases, a party will close out the
contractual commitment before delivery without having to make or take delivery
of the security by purchasing (or selling, as the case may be) on a commodities
exchange an identical futures contract calling for delivery in the same month.
Such a transaction, if effected through a member of an exchange, cancels the
obligation to make or take delivery of the securities. All transactions in the
futures market are made, offset or fulfilled through a clearing house associated
with the exchange on which the contracts are traded. The International Series
will incur brokerage fees when it purchases or sells contracts and will be
required to maintain margin deposits. At the time it enters into a futures
contract, it is required to deposit with its custodian, on behalf of the broker,
a specified amount of cash or eligible securities called "initial margin." The
initial margin required for a futures contract is set by the exchange on which
the contract is traded. Subsequent payments, called "variation margin," to and
from the broker are made on a daily basis as the market price of the futures
contract fluctuates. The costs incurred in connection with futures transactions
could reduce the Series' return. Futures contracts entail risks. If the
investment adviser's judgment about the general direction of interest rates or
markets is wrong, the overall performance may be poorer than if no such
contracts had been entered into.

There may be an imperfect correlation between movements in prices of futures
contracts and portfolio securities being hedged. The degree of difference in
price movements between futures contracts and the securities (or securities
indices) 


                                       4
<PAGE>

being hedged depends upon such things as variations in demand for futures
contracts and securities underlying the contracts and differences between the
liquidity of the markets for such contracts and the securities underlying them.
In addition, the market prices of futures contracts may be affected by certain
factors not directly related to the underlying securities. At any given time,
the availability of futures contracts, and hence their prices, are influenced by
credit conditions and margin requirements. Due to the possibility of price
distortions in the futures market and because of the imperfect correlation
between movements in the prices of securities and movements in the prices of
futures contracts, a correct forecast of market trends by the investment adviser
may not result in a successful hedging transaction.

Options on Financial Futures Contracts. The International Series may purchase
and write call and put options on financial futures contracts. An option on a
futures contract gives the purchaser the right, in return for the premium paid,
to assume a position in a futures contract at a specified exercise price at any
time during the period of the option. Upon exercise, the writer of the option
delivers the futures contract to the holder at the exercise price. The
International Series would be required to deposit with our custodian initial
margin and maintenance margin with respect to put and call options on futures
contracts written by us. Options on futures contracts involve risks similar to
the risks relating to transactions in financial futures contracts described
above. Generally speaking, a given dollar amount used to purchase an option on a
financial futures contract can hedge a much greater value of underlying
securities than if that amount were used to directly purchase the same financial
futures. Should the event that the International Series intends to hedge (or
protect) against not materialize, however, the option may expire worthless, in
which case the International Series would lose the premium paid therefor.

Segregated Accounts. To the extent required to comply with Securities and
Exchange Commission Release 10666 and any related SEC policies, when purchasing
a futures contract, or writing a put option, the International Series will
maintain in a segregated account at its custodian bank cash, U.S. Government and
other permitted securities to cover its position.

OTHER SMALL-CAP SERIES INVESTMENT RESTRICTIONS (WHICH CAN BE CHANGED WITHOUT
SHAREHOLDER APPROVAL)

Repurchase Agreements. If the Small-Cap Series enters into repurchase agreements
as provided in clause (4) of the fundamental investment restrictions above, it
will do so only with those primary reporting dealers that report to the Federal
Reserve Bank of New York and with the 100 largest United States commercial banks
and the underlying securities purchased under the agreements will consist only
of those securities in which the Small-Cap Series otherwise may invest.

Foreign Currency Hedging Techniques. The Small-Cap Series may utilize various
foreign currency hedging techniques described below, including forward foreign
currency contracts and foreign currency put and call options.

Forward Foreign Currency Contracts. A forward foreign currency contract involves
an obligation to purchase or sell a specific amount of a specific currency at a
set price at a future date. The Small-Cap Series expects to enter into forward
foreign currency contracts in primarily two circumstances. First, when the
Small-Cap Series enters into a contract for the purchase or sale of a security
denominated in a foreign currency, it may desire to "lock in" the U.S. dollar
price of the security. By entering into a forward contract for the purchase or
sale of the amount of foreign currency involved in the underlying security
transaction, the Small-Cap Series will be able to protect against a possible
loss resulting from an adverse change in the relationship between the U.S.
dollar and the subject foreign currency during the period between the date the
security is purchased or sold and the date on which payment is made or received.

Second, when management believes that the currency of a particular foreign
country may suffer a decline against the U.S. dollar, the Small-Cap Series may
enter into a forward contract to sell the amount of foreign currency
approximating the value of some or all of the Small-Cap Series' portfolio
securities denominated in such foreign currency or, in the alternative, the
Small-Cap Series may use a cross-hedging technique whereby it sells another
currency which the Small-Cap Series expects to decline in a similar way but
which has a lower transaction cost. Precise matching of the forward contract
amount and the value of the securities involved will not generally be possible
since the future value of such securities denominated in foreign currencies will
change as a consequence of market movements in the value of those securities


                                       5
<PAGE>

between the date the forward contract is entered into and the date it matures.
The Small-Cap Series does not intend to enter into such forward contracts under
this second circumstance on a continuous basis.

Management of the Fund is by its officers on a day to day basis under the
overall supervision of the Board of Directors with advice of Lord, Abbett & Co.

Foreign Currency Put and Call Options. The Small-Cap Series also may purchase
foreign currency put options and write foreign currency call options on U.S.
exchanges or U.S. over-the-counter markets. A put option gives the Small-Cap
Series, upon payment of a premium, the right to sell a currency at the exercise
price until the expiration of the option and serves to insure against adverse
currency price movements in the underlying portfolio assets denominated in that
currency.

Exchange-listed options markets in the United States include several major
currencies, and trading may be thin and illiquid. A number of major investment
firms trade unlisted options which are more flexible than exchange-listed
options with respect to strike price and maturity date. Unlisted options
generally are available in a wider range of currencies. Unlisted foreign
currency options are generally less liquid than listed options and involve the
credit risk associated with the individual issuer. Unlisted options, together
with other illiquid securities, are subject to a limit of 15% of the Small-Cap
Series' net assets.

A call option written by the Small-Cap Series gives the purchaser, upon payment
of a premium, the right to purchase from the Series a currency at the exercise
price until the expiration of the option. The Small-Cap Series may write a call
option on a foreign currency only in conjunction with a purchase of a put option
on that currency. Such a strategy is designed to reduce the cost of downside
currency protection by limiting currency appreciation potential. The face value
of such writing may not exceed 90% of the value of the securities denominated in
such currency invested in by the Small-Cap Series or in such cross currency
(referred to above) to cover such call writing.

Limitations on the Purchases and Sales of Stock Options, Options on Stock
Indices and Stock Index Futures. The Small-Cap Series may write put and call
options on stocks only if they are covered, and such options must remain covered
so long as the Small-Cap Series is obligated as a writer. The Small-Cap Series
will not (a) write puts having an aggregate exercise price greater than 25% of
the Series' total net assets; or (b) purchase (i) put options on stocks not held
in the Small-Cap Series' portfolio, (ii) put options on stock indices or (iii)
call options on stocks or stock indices if, after any such purchase, the
aggregate premiums paid for such options would exceed 20% of the Small-Cap
Series' total net assets.

Call Options on Stock. The Small-Cap Series may, from time to time, write call
options on its portfolio securities. The Small-Cap Series may write only call
options which are "covered," meaning that the Small-Cap Series either owns the
underlying security or has an absolute and immediate right to acquire that
security, without additional cash consideration, upon conversion or exchange of
other securities currently held in its portfolio. In addition, the Small-Cap
Series will not permit the call to become uncovered prior to the expiration of
the option or termination through a closing purchase transaction as described
below. If the Small-Cap Series writes a call option, the purchaser of the option
has the right to buy (and the Series has the obligation to sell) the underlying
security at the exercise price throughout the term of the option. The amount
paid to the Small-Cap Series by the purchaser of the option is the "premium."
The Small-Cap Series' obligation to deliver the underlying security against
payment of the exercise price would terminate either upon expiration of the
option or earlier if the Small-Cap Series were to effect a "closing purchase
transaction" through the purchase of an equivalent option on an exchange. There
can be no assurance that a closing purchase transaction can be effected. The
Small-Cap Series does not intend to write covered call options with respect to
securities with an aggregate market value of more than 5% of it's gross assets
at the time an option is written. This percentage limitation will not be
increased without prior disclosure in our current prospectus.

The Small-Cap Series would not be able to effect a closing purchase transaction
after it had received notice of exercise. In order to write a call option, the
Small-Cap Series is required to comply with the rules of The Options Clearing
Corporation and the various exchanges with respect to collateral requirements.
The Small-Cap Series may not purchase call options except in connection with a
closing purchase transaction. It is possible that the cost of effecting a
closing purchase transaction may be greater than the premium received by the
Small-Cap Series for writing the option.


                                       6
<PAGE>

Generally, the Small-Cap Series intends to write listed covered call options
during periods when it anticipates declines in the market values of portfolio
securities because the premiums received may offset to some extent the decline
in the Small-Cap Series' net asset value occasioned by such declines in market
value. Except as part of the "sell discipline" described below, the Small-Cap
Series will generally not write listed covered call options when it anticipates
that the market values of it's portfolio securities will increase.

One reason for the Small-Cap Series to write call options is as part of a "sell
discipline." If the Small-Cap Series decides that a portfolio security would be
overvalued and should be sold at a certain price higher than the current price,
it could write an option on the stock at the higher price. Should the stock
subsequently reach that price and the option be exercised, the Small-Cap Series
would, in effect, have increased the selling price of that stock, which it would
have sold at that price in any event, by the amount of the premium. In the event
the market price of the stock declined and the option were not exercised, the
premium would offset all or some portion of the decline. It is possible that the
price of the stock could increase beyond the exercise price; in that event, the
Small-Cap Series would forego the opportunity to sell the stock at that higher
price.

In addition, call options may be used as part of a different strategy in
connection with sales of portfolio securities. If, in the judgment of the Fund
Management, the market price of a stock is overvalued and it should be sold, the
Small-Cap Series may elect to write a call option with an exercise price
substantially below the current market price. As long as the value of the
underlying security remains above the exercise price during the term of the
option, the option will, in all probability, be exercised, in which case the
Small-Cap Series will be required to sell the stock at the exercise price. If
the sum of the premium and the exercise price exceeds the market price of the
stock at the time the call option is written, the Small-Cap Series would, in
effect, have increased the selling price of the stock. The Small-Cap Series
would not write a call option in these circumstances if the sum of the premium
and the exercise price were less than the current market price of the stock.

Put Options on Stock. The Small-Cap Series may also write listed put options. If
the Small-Cap Series writes a put option, it is obligated to purchase a given
security at a specified price at any time during the term of the option.

Writing listed put options is a useful portfolio investment strategy when the
Small-Cap Series has cash or other reserves available for investment as a result
of sales of Small-Cap Series shares or, more importantly, because Fund
Management believes a more defensive and less fully invested position is
desirable in light of market conditions. If the Fund Management wishes to invest
its cash or reserves in a particular security at a price lower than current
market value, it may write a put option on that security at an exercise price
which reflects the lower price it is willing to pay. The buyer of the put option
generally will not exercise the option unless the market price of the underlying
security declines to a price near or below the exercise price. If the Small-Cap
Series writes a listed put, the price of the underlying stock declines and the
option is exercised, the premium, net of transaction charges, will reduce the
purchase price paid by the Small-Cap Series for the stock. The price of the
stock may decline by an amount in excess of the premium, in which event the
Small-Cap Series would have foregone an opportunity to purchase the stock at a
lower price.

If, prior to the exercise of a put option, the Small-Cap Series determines that
it no longer wishes to invest in the stock on which the put option had been
written, the Series may be able to effect a closing purchase transaction on an
exchange by purchasing a put option of the same series as the one which it has
previously written. The cost of effecting a closing purchase transaction may be
greater than the premium received on writing the put option and there is no
guarantee that a closing purchase transaction can be effected.

Stock Index Options. Except as describe below, the Small-Cap Series will write
call options on indices only if on such date it holds a portfolio of stocks at
least equal to the value of the index times the multiplier times the number of
contracts. When the Small-Cap Series writes a call option on a broadly-based
stock market index, the Small-Cap Series will segregate or put into escrow with
its custodian, or pledge to a broker as collateral for the option, one or more
"qualified securities" with a market value at the time the option is written of
not less than 100% of the current index value times the multiplier times the
number of contracts.


                                       7
<PAGE>

Segregated Accounts. If the Small-Cap Series has written an option on an
industry or market segment index, it will segregate or put into escrow with its
custodian, or pledge to a broker as collateral for the option, at least ten
"qualified securities," which are securities of an issuer in such industry or
market segment, with a market value at the time the option is written of not
less than 100% of the current index value times the multiplier times the number
of contracts. A "qualified security" is an equity security which is listed on a
national securities exchange or listed on the National Association of Securities
Dealers Automated Quotation System against which the Small-Cap Series has not
written a stock call option and which has not been hedged by the Small-Cap
Series by the sale of stock index futures. Such securities will include stocks
which represent at least 50% of the weighing of the industry or market segment
index and will represent at least 50% of the Small-Cap Series' holdings in that
industry or market segment. No individual security will represent more than 25%
of the amount so segregated, pledged or escrowed. If at the close of business on
any day the market value of such qualified securities so segregated, escrowed or
pledged falls below 100% of the current index value times the multiplier times
the number of contracts, the Small-Cap Series will so segregate, escrow or
pledge an amount in cash, Treasury bills or other high-grade short-term
obligations equal in value to the difference. In addition, when the Small-Cap
Series writes a call on an index which is in-the-money at the time the call is
written, the Small-Cap Series will segregate with its custodian or pledge to the
broker as collateral cash, equity securities, non-investment grade debt, short
term U.S. Government securities or other high-grade short-term debt obligations
equal in value to the amount by which the call is in-the-money times the
multiplier times the number of contracts. Any amount segregated pursuant to the
foregoing sentence may be applied to the Small-Cap Series' obligation to
segregate additional amounts in the event that the market value of the qualified
securities falls below 100% of the current index value times the multiplier
times the number of contracts. However, if the Small-Cap Series holds a call on
the same index as the call written where the exercise price of the call held is
equal to or less than the exercise price of the call written or greater than the
exercise price of the call written if the difference is maintained by the
Small-Cap Series in cash, equity securities, non-investment grade debt, treasury
bills or other high-grade short-term obligations in a segregated account with
its custodian, it will not be subject to the requirements describe in this
paragraph. In instances involving the purchase of stock index futures contracts
by the Small-Cap Series, an amount of cash or permitted securities equal to the
market value of the futures contracts will be deposited in a segregated account
with the its custodian and/or in a margin account with a broker to collateralize
the position and thereby insure that the use of such futures are unleveraged.

Under regulations of the Commodity Exchange Act, investment companies registered
under the Act are exempt from the definition of "commodity pool operator,"
provided all of the Small-Cap Series' commodity futures or commodity options
transactions constitute bona fide hedging transactions within the meaning of the
CFTC's regulations. The Small-Cap Series will use stock index futures and
options on futures as described herein in a manner consistent with this
requirement.

Stock Index Futures. The Small-Cap Series will engage in transactions in stock
index futures contracts as a hedge against changes resulting from market
conditions in the values of securities which are held in the Small-Cap Series'
portfolio or which it intends to purchase. The Small-Cap Series will engage in
such transactions when they are economically appropriate for the reduction of
risks inherent in the ongoing management of the Small-Cap Series. The Small-Cap
Series may not purchase or sell stock index futures if, immediately thereafter,
more than one-third of its net assets would be hedged and, in addition, except
as described above in the case of a call written and held on the same index,
will write call options on indices or sell stock index futures only if the
amount resulting from the multiplication of the then current level of the index
(or indices) upon which the option or future contract(s) is based, the
applicable multiplier(s), and the number of futures or options contracts which
would be outstanding, would not exceed one-third of the value of the Small-Cap
Series' net assets.

RISK FACTORS -  SMALL-CAP SERIES

Risks of Transactions in Stock Options. Writing options involves the risk that
there will be no market in which to effect a closing transaction. An option
position may be closed out only on an exchange which provides a secondary market
for an option of the same series. Although the Small-Cap Series will generally
write only those options for which there appears to be an active secondary
market, there is no assurance that a liquid secondary market on an exchange will
exist for any particular option, or at any particular time, and for some options
no secondary market on an exchange may exist. If the Small-Cap Series, as a
covered call option writer, is unable to effect a closing purchase transaction
in a secondary market, it will not be able to sell the underlying security until
the option expires or it delivers the underlying security upon exercise.


                                       8
<PAGE>

Risks of Options on Indices. The Small-Cap Series' purchase and sale of options
on indices will be subject to risks described above under "Risk of Transactions
in Stock Options." In addition, the distinctive characteristics of options on
indices create certain risks that are not present with stock options.

Because the value of an index option depends upon movements in the level of the
index rather than the price of a particular stock, whether the Small-Cap Series
will realize a gain or loss on the purchase or sale of an option on an index
depends upon movements in the level of stock prices in the stock market
generally or in an industry or market segment rather than movements in the price
of a particular stock. Accordingly, successful use by the Small-Cap Series of
options on indices would be subject to the investment adviser's ability to
predict correctly movements in the direction of the stock market generally or of
a particular industry. This requires different skills and techniques than
predicting changes in the price of individual stocks.

Index prices may be distorted if trading of certain stocks included in the index
is interrupted. Trading in the index option also may be interrupted in certain
circumstances, such as if trading were halted in a substantial number of stocks
included in the index. If this occurred, the Small-Cap Series would not be able
to close out options which it had purchased or written and, if restrictions on
exercise were imposed, may be unable to exercise an option it holds, which could
result in substantial losses to the Small-Cap Series. It is the Small-Cap
Series' policy to purchase or write options only on indices which include a
number of stocks sufficient to minimize the likelihood of a trading halt in the
index.

Trading in index options commenced in April 1983 with the S&P 100 option
(formerly called the CBOE 100). Since that time a number of additional index
option contracts have been introduced including options on industry indices.
Although the markets for certain index option contracts have developed rapidly,
the markets for other index options are still relatively illiquid. The ability
to establish and close out positions on such options will be subject to the
development and maintenance of a liquid secondary market. It is not certain that
this market will develop in all index option contracts. The Small-Cap Series
will not purchase or sell any index option contract unless and until, in Fund
management's opinion, the market for such options has developed sufficiently
that such risk in connection with such transactions in no greater than such risk
in connection with options on stocks.

Special Risks of Writing Calls on Indices. Because exercises of index options
are settled in cash, a call writer cannot determine the amount of its settlement
obligations in advance and, unlike call writing on specific stocks, cannot
provide in advance for, or cover, its potential settlement obligations by
acquiring and holding the underlying securities. However, the Small-Cap Series
will write call options on indices only under the circumstances described above
under "Limitations on the Purchases and Sales of Stock Options, Options on Stock
Indices and Stock Index Futures."

Price movements in the Small-Cap Series' portfolio probably will not correlate
precisely with movements in the level of the index and, therefore, the Series
bears the risk that the price of the securities held may not increase as much as
the index. In such event the Small-Cap Series would bear a loss on the call
which is not completely offset by movements in the price of the Small-Cap
Series' portfolio. It is also possible that the index may rise when the
Small-Cap Series' portfolio of stocks does not rise. If this occurred, the
Small-Cap Series would experience a loss on the call which is not offset by an
increase in the value of its portfolio and might also experience a loss in its
portfolio. However, because the value of a diversified portfolio will, over
time, tend to move in the same direction as the market, movements in the value
of the Small-Cap Series in the opposite direction to the market would be likely
to occur for only a short period or to a small degree.

Unless the Small-Cap Series has other liquid assets that are sufficient to
satisfy the exercise of a call, the Small-Cap Series would be required to
liquidate portfolio securities in order to satisfy the exercise. Because an
exercise must be settled within hours after receiving the notice of exercise, if
the Small-Cap Series fails to anticipate an exercise, it may have to borrow (in
amounts not exceeding 20% of the Series' total assets) pending settlement of the
sale of securities in its portfolio and would incur interest charges thereon.

When the Small-Cap Series has written a call, there is also a risk that the
market may decline between the time the call is written and the time the
Small-Cap Series is able to sell stocks in its portfolio. As with stock options,
the Small-Cap Series 


                                       9
<PAGE>

will not learn that an index option has been exercised until the day following
the exercise date but, unlike a call on stock where the Small-Cap Series would
be able to deliver the underlying securities in settlement, the Series may have
to sell part of its stock portfolio in order to make settlement in cash, and the
price of such stocks might decline before they can be sold. This timing risk
makes certain strategies involving more than one option substantially more risky
with index options than with stock options. For example, even if an index call
which the Small-Cap Series has written is "covered" by an index call held by the
Small-Cap Series with the same strike price, the Small-Cap Series will bear the
risk that the level of the index may decline between the close of trading on the
date the exercise notice is filed with the clearing corporation and the close of
trading on the date the Small-Cap Series exercises the call it holds or the time
the Small-Cap Series sells the call which in either case would occur no earlier
than the day following the day the exercise notice was filed.

Special Risks of Purchasing Puts and Calls on Indices. If the Small-Cap Series
holds an index option and exercises it before final determination of the closing
index value for that day, it runs the risk that the level of the underlying
index may change before closing. If such a change causes the exercised option to
fall out-of-the-money, the Series will be required to pay the difference between
the closing index value and the exercise price of the option (times the
applicable multiple) to the assigned writer. Although the Small-Cap Series may
be able to minimize this risk by withholding exercise instructions until just
before the daily cut off time or by selling rather than exercising an option
when the index level is close to the exercise price it may not be possible to
eliminate this risk entirely because the cut off times for index options may be
earlier than those fixed for other types of options and may occur before
definitive closing index values are announced.

(2)   The amounts in Column 3 were accrued by the Lord Abbett-Sponsored Funds
      for the 12 months ended October 31, 1997 with respect to the equity based
      plans established for independent directors in 1996. This plan supercedes
      a previously approved retirement plan for all future directors. Current
      directors had the option to convert their accrued benefits under the
      retirement plan. All of the outside directors except one made such an
      election.

(3)   This column shows aggregate compensation, including directors fees and
      attendance fees for board and committee meetings, of a nature referred to
      in footnote one, accrued by the Lord Abbett-sponsored funds during the
      year ended December 31, 1997.

(4)   Mr. Jansing chose to continue to receive benefits under the retirement
      plan, which provides that outside directors (trustees) may receive annual
      retirement benefits for life equal to their final annual retainer
      following retirement at or after age 72 with at least ten years of
      service. Thus, if Mr. Jansing were to retire and the annual retainer
      payable by the funds were the same as it is today, he would receive annual
      retirement benefits of $50,000.

The Funds' By-Laws provide that each Fund shall not hold an annual meeting of
its stockholders in any year unless one or more matters are required to be acted
on by stockholders under the Investment Company Act of 1940, as amended (the
"Act"), or unless called by a majority of the Board of Directors (Trustees) or
by shareholders holding at least one quarter of the stock of each Fund
outstanding and entitled to vote at the meeting. When any such annual meeting is
held, the shareholders will elect directors (trustees) and vote on the approval
of the independent auditors of each Fund, except for International Series.

As of March 1, 1998 our officers and directors as a group owned less than 1% of
each Fund's outstanding shares.

Under its Management Agreement, Small-Cap Series is obligated to pay Lord Abbett

operations) to November 30, 1996, the management fees paid to Lord Abbett by the
Small-Cap Series amounted to $1,075,019 and $0 , respectively. Under its

Fund's custodian. In accordance with the requirements of Rule 17f-5, each Fund's
directors (trustees) have approved arrangements permitting each Fund's foreign
assets not held by BNY or its foreign branches to be held by certain qualified
foreign banks and depositories.

The Sub-Custodians of BNY are:

                            4. Portfolio Transactions

Our policy is to obtain best execution on all our portfolio transactions, which
means that we seek to have purchases and sales of portfolio securities executed
at the most favorable prices, considering all costs of the transaction including
brokerage commissions and dealer markups and markdowns and taking into account
the full range and quality of the brokers' services. Consistent with obtaining
best execution, we generally pay, as described below, a higher commission than
some brokers might charge on the same transactions. Our policy with respect to
best execution governs the selection of brokers or dealers and the market in
which the transaction is executed. To the extent permitted by law, we may, if
considered advantageous, make a purchase from or sale to another Lord
Abbett-sponsored fund without the intervention of any broker-dealer.

Broker-dealers are selected on the basis of their professional capability and
the value and quality of their brokerage and research services. Normally, the
selection is made by traders who are officers of the Fund and also are employees
of Lord Abbett. These traders do the trading as well for other accounts --
investment companies (of which they are also officers) and other investment
clients -- managed by Lord Abbett. They are responsible for obtaining best
execution.

We pay a commission rate that we believe is appropriate to give maximum
assurance that our brokers will provide us, on a continuing basis, the highest
level of brokerage services available. While we do not always seek the lowest
possible commissions on particular trades, we believe that our commission rates
are in line with the rates that many other institutions pay. Our traders are
authorized to pay brokerage commissions in excess of those that other brokers
might accept on the same transactions in recognition of the value of the
services performed by the executing brokers, viewed in terms of either the
particular transaction or the overall responsibilities of Lord Abbett with
respect to us and the other accounts they manage. 


                                       15
<PAGE>

Such services include showing us trading opportunities including blocks, a
willingness and ability to take positions in securities, knowledge of a
particular security or market proven ability to handle a particular type of
trade, confidential treatment, promptness and reliability.

Some of these brokers also provide research services at least some of which are
useful to Lord Abbett in their overall responsibilities with respect to us and
the other accounts they manage. Research includes the furnishing of analyses and
reports concerning issuers, industries, securities, economic factors and trends,
portfolio strategy and the performance of accounts and trading equipment and
computer software packages, acquired from third-party suppliers, that enable
Lord Abbett to access various information bases. Such services may be used by
Lord Abbett in servicing all their accounts, and not all of such services will
necessarily be used by Lord Abbett in connection with their management of the
Fund; conversely, such services furnished in connection with brokerage on other
accounts managed by Lord Abbett may be used in connection with their management
of the Fund, and not all of such services will necessarily be used by Lord
Abbett in connection with their advisory services to such other accounts. We
have been advised by Lord Abbett that research services received form brokers
cannot be allocated to any particular account, are not a substitute for Lord
Abbett's services but are supplemental to their own research effort and, when
utilized, are subject to internal analysis before being incorporated by Lord
Abbett into their investment process. As a practical matter, it would not be
possible for Lord Abbett to generate all of the information presently provided
by brokers. While receipt of research services from brokerage firms has not
reduced Lord Abbett's normal research activities, the expenses of Lord Abbett
could be materially increased if it attempted to generate such additional
information through its own staff and purchased such equipment and software
packages directly from the suppliers.

No commitments are made regarding the allocation of brokerage business to or
among brokers, and trades are executed only when they are dictated by investment
decisions of the Fund to purchase or sell portfolio securities.

If two or more broker-dealers are considered capable of offering the equivalent
likelihood of best execution, the broker-dealer who has sold our shares and/or
shares of other Lord Abbett-sponsored funds may be preferred.

If other clients of Lord Abbett buy or sell the same security at the same time
as we do, transactions will, to the extent practicable, be allocated among all
participating accounts in proportion to the amount of each order and will be
executed daily until filled so that each account shares the average price and
commission cost of each day. Other clients who direct that their brokerage
business be placed with specific brokers or who invest through wrap accounts
introduced to Lord Abbett by certain brokers may not participate with us in the
buying and selling of the same securities as described above. If these clients
wish to buy or sell the same security as we do, they may have their transactions
executed at times different from our transactions and thus may not receive the
same price or incur the same commission cost as we do.

We will not seek "reciprocal" dealer business (for the purpose of applying
commissions in whole or in part for our benefit or otherwise) from dealers as
consideration for the direction to them of portfolio business.

For the fiscal years ended October 31, 1997, 1996 and 1995, Affiliated Fund paid
total commissions to independent dealers of $7,681,037, $5,897,259 and
$6,542,354, respectively.

For the period December 13, 1995 (commencement of operations) to November 30,
1996 and the year ended November 30, 1997, the Small-Cap Series paid total
commissions to independent broker-dealers of $45,266 and 1,812,425,
respectively.

For the period December 13, 1996 (commencement of operations) through October
31, 1997, the International Series paid total commissions to independent
broker-dealers of $108,270.

During the fiscal years ending December 31, 1997, 1996 and 1995, the
Bond-Debenture Fund paid total commissions to independent broker-dealers of
$14,773,720, $8,760,174 and $6,717,922, respectively.

               5. Purchases, Redemptions and Shareholder Services

Information concerning how we value our shares for the purchase and redemption
of our shares is contained in the Prospectus under "Purchases" and
"Redemptions," respectively.

As disclosed in the Prospectus, we calculate our net asset value as of the close
of the New York Stock Exchange ("NYSE") on each day that the NYSE is open for
trading by dividing our total net assets by the number of shares outstanding at
the time of calculation. The NYSE is closed on Saturdays and Sundays and the
following holidays -- New Year's Day, Martin Luther King Jr. Day, Presidents'
Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and
Christmas.

Each Fund values its portfolio securities at market value as of the close of the
NYSE. Market value will be determined as follows: securities listed or admitted
to trading privileges on the New York or American Stock Exchange or on the
NASDAQ National Market System are valued at the last sales price, or, if there
is no sale on that day, at the mean between the last bid and asked prices, or,
in the case of bonds, in the over-the-counter market if, in the judgment of the
Fund's officers, that market more accurately reflects the market value of the
bonds. Over-the-counter securities not traded on the NASDAQ National Market
System are valued at the mean between the last bid and asked prices. Securities
for which market quotations are not available are valued at fair market value
under procedures approved by the Board of Directors (Trustees).

The net asset value per share for the Class Y shares will be determined by
taking Class Y shares net assets and dividing by shares outstanding. Our Class Y
shares will be offered at net asset value.

Each Fund has entered into a distribution agreement with Lord Abbett Distributor
LLC, a New York limited liability company ("Lord Abbett Distributor") and
subsidiary of Lord Abbett under which Lord Abbett Distributor is obligated to
use its best efforts to find purchasers for the shares of each Fund, and to make
reasonable efforts to sell Fund shares so long as, in Lord Abbett Distributor's
judgment, a substantial distribution can be obtained by reasonable efforts.

Class Y Share Exchanges. The Prospectus briefly describes the Telephone Exchange
Privilege. You may exchange some or all of your Y shares for Y shares of any
Lord Abbett-sponsored funds currently offering Class Y shares to the public.
Currently those funds are Affiliated Fund, Small-Cap Series, International
Series, Bond-Debenture Fund, and Developing Growth Fund.

Redemptions. A redemption order is in proper form when it contains all of the
information and documentation required by the order form or supplementally by
Lord Abbett Distributor or the Fund to carry out the order. The signature(s) and
any legal capacity of the signer(s) must be guaranteed by an eligible guarantor.
See each Prospectus for expedited redemption procedures.

The right to redeem and receive payment, as described in each Prospectus, may be
suspended if the NYSE is closed (except for weekends or customary holidays),
trading on the NYSE is restricted or the Securities and Exchange Commission
deems an emergency to exist.

Our Board of Directors (Trustees) may authorize redemption of all of the shares
in any account in which there are fewer than 25 shares (Affiliated Fund,
Bond-Debenture Fund and Small-Cap Series) and 60 shares (International Series).
Before authorizing such redemption, the Board must determine that it is in our
economic best interest or necessary to reduce disproportionately burdensome
expenses in servicing shareholder accounts. At least 6 month's prior written
notice will be given before any such redemption, during which time shareholders
may avoid redemption by bringing their accounts up to the minimum set by the
Board.


                                       17
<PAGE>

                               6. Past Performance

Each Fund computes the annual compounded rate of total return for Class Y shares
during specified periods that would equate the initial amount invested to the
ending redeemable value of such investment by adding one to the computed average
annual total return, raising the sum to a power equal to the number of years
covered by the computation and multiplying the result by one thousand dollars,
which represents a hypothetical initial investment. The calculation assumes
deduction of no sales charge from the initial amount invested and reinvestment
of all income dividends and capital gains distributions on the reinvestment
dates at prices calculated as stated in each Prospectus. The ending redeemable
value is determined by assuming a complete redemption at the end of the
period(s) covered by the annual total return computation.

In calculating total returns for Class Y shares no sales charge is deducted from
the initial investment and the return is shown at net asset value. Total returns
also assume that all dividends and capital gains distributions during the period
are reinvested at net asset value per share, and that the investment is redeemed
at the end of the period.

Class Y share performance. Using the computation method described above,
Affiliated Fund's total return for Class Y shares for the one-month period
ending April 30, 1998 was .19%. For the five-month period ending May 31, 1998,
the total return for the Small-Cap Series was 6.49%. For the four-month period
ending April 30, 1998, the total return for the International Series was 29.43%
(not annualized).

Our yield quotation for Class Y shares is based on a 30-day period ended on a
specified date, computed by dividing the net investment income per share earned
during the period by the net asset value per share of such class on the last day
of the period. This is determined by finding the following quotient: take the
dividends and interest earned during the period for the class minus its expenses
accrued for the period and divide by the product of (i) the average daily number
of Class shares outstanding during the period that were entitled to receive
dividends and (ii) the net asset value per share of such class on the last day
of the period. To this quotient add one. This sum is multiplied by itself five
times. Then one is subtracted from the product of this multiplication and the
remainder is multiplied by two. Yields for Class Y shares do not reflect the
deduction of any sales charge.

These figures represent past performance, and an investor should be aware that
the investment return and principal value of a Series' investment will fluctuate
so that an investor's shares, when redeemed, may be worth more or less than
their original cost. Therefore, there is no assurance that this performance will
be repeated in the future.

                                    7. Taxes

The value of any shares redeemed by each Fund or repurchased or otherwise sold
may be more or less than your tax basis in the shares at the time the
redemption, repurchase or sale is made. Any gain or loss will generally be
taxable for federal income tax purposes. Any loss realized on the sale,
redemption or repurchase of a Fund's shares which you have held for six months
or less will be treated for tax purposes as a long-term capital loss to the
extent of any capital gains distributions which you received with respect to
such shares. Losses on the sale of stock or securities are not deductible if,
within a period beginning 30 days before the date of the sale and ending 30 days
after the date of the sale, the taxpayer acquires stock or securities that are
substantially identical.

Each Fund will be subject to a four-percent nondeductible excise tax on certain
amounts not distributed (and not treated as having been distributed) on a timely
basis in accordance with a calendar-year distribution requirement. Each Fund
intends to distribute to shareholders each year an amount adequate to avoid the
imposition of such excise tax.

The writing of call options and other investment techniques and practices which
each Fund may utilize, as described above under "Investment Objectives and
Policies," may create "straddles" for United States federal income tax purposes
and may affect the character and timing of the recognition of gains and losses
by a Fund. Such transactions may increase the amount of short-term capital gain
realized by each Fund, which is taxed as ordinary income when distributed to
shareholders. Limitations imposed by the Internal Revenue Code on regulated
investment companies may restrict each Fund's ability to engage in transactions
in options.


                                       18
<PAGE>

Certain futures contracts and certain listed options held by a Fund will be
required to be "marked to market" for federal income tax purpose, i.e., treated
as having been sold at their fair market value on the last day of the Fund's
taxable year (referred to as Section 1256 Contracts). Sixty percent of any gain
or loss recognized on actual or deemed sales of such Section 1256 Contracts will
be treated as long-term capital gain or loss, and 40% of such gain or loss will
be treated as short-term capital gain or loss. Each Fund may be required to
defer the recognition of losses on securities and options and futures contracts
to the extent of any recognized gain on offsetting positions held by the Fund.

As described in the Prospectus under "How We Invest - Risk Factors," each Fund
may be subject to foreign withholding taxes which would reduce the yield on its
investments. Tax treaties between certain countries and the United States may
reduce or eliminate such taxes. It is expected that shareholders of each Fund
who are subject to United States federal income tax will not be entitled to
claim a federal income tax credit or deduction for foreign income taxes paid by
each Fund.

Gains and losses realized by each Fund on certain transactions, including sales
of foreign debt securities and certain transactions involving foreign currency,
will be treated as ordinary income or loss for federal income tax purposes to
the extent, if any, that such gains or losses are attributable to changes in
exchange rates for foreign currencies. Accordingly, distributions taxable as
ordinary income will include the net amount, if any, of such foreign exchange
gains and will be reduced by the net amount, if any, of such foreign exchange
losses.

If either Fund purchases shares in certain foreign investment entities, called
"passive foreign investment companies," it may be subject to United States
federal income tax on a portion of any "excess distribution" or gain from the
disposition of such shares, even if such income is distributed as a taxable
dividend by the Fund to its shareholders. Additional charges in the nature of
interest may be imposed on either the Fund or its shareholders in respect to
deferred taxes arising from such distributions or gains.

If a Fund were to invest in a passive foreign investment company with respect to
which a Fund elected to make a "qualified electing fund" election, in lieu of
the foregoing requirements, the Fund might be required to include in income each
year a portion of the ordinary earnings and net capital gains of the qualified
electing fund, even if such amount were not distributed to a Fund.

Dividends paid by a Fund will qualify for the dividends-received deduction for
corporations to the extent they are derived from dividends paid by domestic
corporations.


                                       19
<PAGE>

The foregoing discussion relates solely to U.S. federal income tax law as
applicable to United States persons (United States citizens or residents and
United States domestic corporations, partnerships, trusts and estates). Each
shareholder who is not a United States person should consult his tax advisor
regarding U.S. and foreign tax consequences of the ownership of shares of a
Fund, including a 30% (or lower treaty rate) United States withholding tax on
dividends representing ordinary income and net short-term capital gains, and the
applicability of United States gift and estate taxes to non-United States gift
and estate taxes to non-United States persons who own Fund shares.

                         8. Information About the Funds

The directors, trustees and officers of Lord Abbett-sponsored mutual funds,
together with the partners and employees of Lord Abbett, are permitted to
purchase and sell securities for their personal investment accounts. In engaging
in personal securities transactions, however, such persons are subject to
requirements and restrictions contained in the Fund's Code of Ethics which
complies, in substance, with each of the recommendations of the Investment
Company Institute's Advisory Group on Personal Investing. Among other things,
the Code requires that Lord Abbett partners and employees obtain advance
approval before buying or selling securities, submit confirmations and quarterly
transaction reports, and obtain approval before becoming a director of any
company; and it prohibits such persons from investing in a security 7 days
before or after any Lord Abbett-sponsored fund or Lord Abbett-managed account
considers a trade or trades in such security, prohibiting profiting on trades of
the same security within 60 days and trading on material and non-public
information. The Code imposes certain similar requirements and restrictions on
the independent directors and trustees of each Lord Abbett-sponsored mutual fund
to the extent contemplated by the recommendations of such Advisory Group.

                             Corporate Bond Ratings

Moody's Investors Service, Inc.'s Corporate Bond Ratings

Aaa - Bonds which are rated Aaa are judged to be of the best quality and carry
the smallest degree of investment risk. Interest payments are protected by a
large or by an exceptionally stable margin, and principal is secure. While the
various protective elements are likely to change, such changes as can be
visualized are most unlikely to impair the fundamentally strong position of such
issues.

Aa - Bonds which are rated Aa are judged to be of high-quality by all standards.
Together with the Aaa group, they comprise what are generally known as
high-grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities, fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long-term risks appear somewhat larger than in Aaa securities.

A - Bonds which are rated A possess many favorable investment attributes and are
to be considered as upper medium-grade obligations. Factors giving security to
principal and interest are considered adequate but elements may be present which
suggest a susceptibility to impairment sometime in the future.

Baa - Bonds which are rated Baa are considered as medium-grade obligations,
i.e., they are neither highly protected nor poorly secured. Interest payments
and principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and, in
fact, have speculative characteristics as well.

Ba - Bonds which are rated Ba are judged to have speculative elements; their
future cannot be considered as well assured. Often the protection of interest
and principal payments may be very moderate and thereby not well safeguarded
during both good and bad times over the future. Uncertainty of position
characterizes bonds in this class.

B - Bonds which are rated B generally lack characteristics of a desirable
investment. Assurance of interest and principal payments or of maintenance and
other terms of the contract over any long period of time may be small.

Caa - Bonds that are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.

Ca - Bonds that are rated Ca represent obligations which are speculative in a
high degree. Such issues are often in default or have other marked shortcomings.

C - Bonds that are rated C are the lowest-rated class of bonds and issues so
rated can be regarded as having extremely poor prospects of ever attaining any
real investment standing.

Standard & Poor's Corporation's Corporate Bond Ratings

AAA - This is the highest rating assigned by Standard & Poor's to a debt
obligation and indicates an extremely strong capacity to pay principal and
interest.

AA - Bonds rated AA also qualify as high-quality debt obligations. Capacity to
pay principal and interest is very strong and in the majority of instances they
differ from AAA issues only in small degree.

A - Bonds rated A have a strong capacity to pay principal and interest, although
they are somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions. 


                                       21
<PAGE>

BBB - Bonds rated BBB are regarded as having an adequate capacity to pay
principal and interest. Whereas they normally exhibit adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay principal and interest for bonds in
this category than for bonds in the A category.

BB-B-CCC-CC-C - Debt rated BB, B, CCC, CC and C is regarded as having
predominately speculative characteristics with respect to capacity to pay
interest and repay principal. 'BB' indicates the least degree of speculation and
'CCC' the highest. While such debt will likely have some quality and protective
characteristics, these are outweighed by large uncertainties or major risk
exposures to adverse conditions.

D - Debt rated 'D' is in payment default. The 'D' rating category is used when
interest payments or principal payments are not made on the date due even if the
applicable grace period has not expired, unless S&P believes such payments will
be made during such grace period. The 'D' rating also will be used upon the
filing of a bankruptcy petition if debt service payments are jeopardized.

Item 27. Indemnification

         Registrant is incorporated  under the laws of the State of Maryland and
         is  subject  to  Section  2-418 of the  Corporations  and  Associations
         Article of the Annotated Code of the State of Maryland  controlling the
         indemnification of the directors and officers. Since Registrant has its
         executive  offices  in the State of New  York,  and is  qualified  as a
         foreign  corporation  doing business in such State, the persons covered
         by the  foregoing  statute  may also be  entitled to and subject to the
         limitations of the indemnification provisions of Section 721-726 of the
         New York Business Corporation Law.

         The general effect of these statutes is to protect officers,  directors
         and  employees  of  Registrant  against  legal  liability  and expenses
         incurred by reason of their positions with the Registrant. The statutes
         provide for  indemnification  for liability for proceedings not brought
         on behalf of the  corporation  and for those  brought  on behalf of the
         corporation,   and  in  each  case   place   conditions   under   which
         indemnification  will be  permitted,  including  requirements  that the
         officer,  director  or  employee  acted in good  faith.  Under  certain
         conditions,  payment of expenses in advance of final disposition may be
         permitted. The By-Laws of Registrant, without limiting the authority of
         Registrant to indemnify any of its officers, employees or agents to the
         extent consistent with applicable law, makes the indemnification of its
         directors  mandatory  subject only to the  conditions  and  limitations
         imposed by the above-mentioned Section 2-418 of Maryland Law and by the
         provisions  of Section 17(h) of the  Investment  Company Act of 1940 as
         interpreted  and required to be implemented by SEC Release No. IC-11330
         of September 4, 1980.

         In referring in its By-Laws to, and making indemnification of directors
         subject to the conditions and limitations of, both Section 2-418 of the
         Maryland Law and Section 17(h) of the  Investment  Company Act of 1940,
         Registrant intends that conditions and limitations on the extent of the
         indemnification  of  directors  imposed  by the  provisions  of  either
         Section 2-418 or Section  17(h) shall apply and that any  inconsistency
         between the two will be resolved by  applying  the  provisions  of said
         Section 17(h) if the  condition or limitation  imposed by Section 17(h)
         is the more  stringent.  In referring in its By-Laws to SEC Release No.
         IC-11330 as the source for  interpretation  and  implementation of said
         Section 17(h),  Registrant  understands that it would be required under
         its By-Laws to use  reasonable  and fair means in  determining  whether
         indemnification  of a  director  should be made and  undertakes  to use
         either  (1) a final  decision  on the  merits by a court or other  body
         before  whom  the   proceeding  was  brought  that  the  person  to  be
         indemnified  ("indemnitee")  was not  liable  to  Registrant  or to its
         security  holders by reason of willful  malfeasance,  bad faith,  gross
         negligence, or reckless disregard of the duties involved in the conduct
         of his office  ("disabling  conduct")  or (2) in the  absence of such a
         decision, a reasonable determination, based upon a review of the facts,
         that the indemnitee was not liable by reason of such disabling conduct,
         by (a) the vote of a majority of a quorum of directors  who are neither
         "interested  persons"  (as defined in the 1940 Act) of  Registrant  nor
         parties to the  proceeding,  or (b) an  independent  legal counsel in a
         written opinion. Also, Registrant will make advances of attorneys' fees
         or other  expenses  incurred by a director  in his defense  only if (in
         addition  to  his  undertaking  to  repay  the  advance  if he  is  not
         ultimately entitled to  indemnification)  (1) the indemnitee provides a
         security for his  undertaking,  (2) Registrant shall be insured against
         losses arising by reason of any lawful advances, or (3) a majority of a
         quorum of the non-interested,  non-party directors of Registrant, or an
         independent legal counsel in a written opinion, shall determine,  based
         on a review of readily available facts, that there is reason to believe
         that   the   indemnitee   ultimately   will  be   found   entitled   to
         indemnification.
<PAGE>
         Insofar as  indemnification  for liability arising under the Securities
         Act of 1933 may be permitted  to  directors,  officers and  controlling
         persons of the  Registrant  pursuant to the  foregoing  provisions,  or
         otherwise,  the  Registrant has been advised that in the opinion of the
         Securities  and Exchange  Commission  such  indemnification  is against
         public policy as expressed in the Act and is, therefore, unenforceable.
         In the event that a claim for indemnification  against such liabilities
         (other than the payment by the  Registrant of expense  incurred or paid
         by a director,  officer or controlling  person of the Registrant in the
         successful  defense of any action,  suit or  proceeding) is asserted by
         such  director,  officer or controlling  person in connection  with the
         securities being registered, the Registrant will, unless in the opinion
         of its counsel the matter has been  settled by  controlling  precedent,
         submit to a court of appropriate jurisdiction the question whether such

         contains certain exclusions, among which is exclusion from coverage for

         fines or penalties imposed by law or other matters deemed uninsurable.
