LORD ABBETT RESEARCH FUND, INC.
The General Motors Building
767 Fifth Avenue
New York, NY 10153-0203
800-426-1130

Lord Abbett  Research  Fund,  Inc.,  (the  "Fund"),  is a mutual fund  currently
consisting  of three  series.  Only  shares of two of those  series--  Large-Cap
Series  and  Small-Cap  Series  ("we"  or the  "Series")  are  offered  by  this
Prospectus.  Each Series has three classes called Class A, B and C shares, which
provide investors with different  investment options in purchasing shares of the
Series. See "Purchases" for a description of these choices.

The Large-Cap  Series'  investment  objective is growth of capital and growth of
income  consistent  with  reasonable  risk.  Production  of current  income is a
secondary  consideration.  The Large-Cap Series seeks to attain its objective by
investing  in  a  broad  range  of  companies  whose  common  stocks  (including
securities  convertible into common stocks) are selling at attractive prices and
therefore represent fundamental  investment value. These companies are primarily
large-sized, based on the value of their outstanding equity securities.

The  Small-Cap  Series'  investment  objective  is  to  seek  long-term  capital
appreciation.  The Series will seek its objective through investments  primarily
in equity securities which are believed to be undervalued in the marketplace. In
its search for value,  the Small-Cap  Series seeks companies which are primarily
small-sized,  based on the value of their outstanding stock. These companies are
often out of favor or not closely  followed by investors  and, as a result,  may
offer substantial appreciation potential over time.

There can be no assurance that each Series will achieve its objective.

This Prospectus  sets forth  concisely the  information  about the Fund and each
Series that a  prospective  investor  should know before  investing.  Additional
information  about the Fund and each  Series has been filed with the  Securities
and Exchange  Commission  and is  available  upon request  without  charge.  The
Statement of  Additional  Information  is  incorporated  by reference  into this
Prospectus and may be obtained,  without charge, by writing directly to the Fund
or by calling  800-874-3733.  Ask for "Part B of the Prospectus -- The Statement
of Additional Information".

The  date of this  Prospectus,  and the  date  of the  Statement  of  Additional
Information, is April 1, 1997.

PROSPECTUS
Investors should read and retain this Prospectus.  Shareholder  inquiries should
be made in writing directly to the Fund or by calling 800-821-5129. You can also
make inquiries through your broker-dealer.

Shares of each  Series are not  deposits or  obligations  of, or  guaranteed  or
endorsed by, any bank,  and the shares are not federally  insured by the Federal
Deposit Insurance  Corporation,  the Federal Reserve Board, or any other agency.
An  investment  in the Series  involves  risks,  including  the possible loss of
principal.

(1)Although  the Fund does not,  with respect to the Class B and Class C shares,
charge a  front-end  sales  charge,  investors  should be aware  that  long-term
shareholders  may pay, under each Rule 12b-1 plan  applicable to the Class B and
Class C shares of the Fund (both of which pay  annual  0.25%  service  and 0.75%
distribution  fees), more than the economic  equivalent of the maximum front-end
sales  charge as  permitted  by certain  rules of the  National  Association  of
Securities  Dealers,  Inc. Likewise,  with respect to Class A shares,  investors
should be aware that,  over the long term,  such  maximum may be exceeded due to
the Rule 12b-1 plan  applicable  to Class A shares which permits the Fund to pay
up to 0.50% in total  annual  fees,  half for  service  and the  other  half for
distribution.  The 12b-1  fees for the  Class A shares  have  been  restated  to
reflect the current fees under the recently amended Class A 12b-1 Plans.

(2)Sales  "load" is  referred  to as sales  "charge",  "deferred  sales load" is
referred to as  "contingent  deferred sales charge" (or "CDSC") and "12b-1 fees"
which  consist of a "service  fee" and a  "distribution  fee" are referred to by
either or both of these terms where appropriate with respect to Class A, Class B
and Class C shares throughout this Prospectus.

(3)Class  B shares  will  automatically  convert to Class A shares on the eighth
anniversary of the purchase of Class B shares.

(4)For Class A and B shares,  the annual operating expenses shown in the summary
have been restated from November 30, 1996 fiscal-year amounts to reflect current
fees.  For the Class C shares,  annual  operating  expenses have been  estimated
based on expenses  incurred by Class A and B shares  because Class C shares were
not available for purchase  prior to April 1, 1997. The foregoing is provided to
give  investors a better  understanding  of the expenses that are incurred by an
investment in a Series.

4    HOW WE INVEST

Large-Cap  Series.  The  Large-Cap  Series  invests  primarily in common  stocks
(including  securities  convertible into common stocks such as  investment-grade
convertible   bonds  or   convertible-preferred   stocks)  of  companies   whose
outstanding  equity  securities have an aggregate  market value of at least $1.5
billion. Under normal circumstances, at least 65% of the Large-Cap Series' total
assets will consist of investments  made in large-cap  companies,  determined at
the time of purchase.  These  companies will have good prospects for improvement
in  earnings  trends  or asset  values.  The  Large-Cap  Series  will  invest in
companies on the basis of the fundamental economic and business factors (such as
government,  fiscal and  monetary  policies,  employment  levels,  demographics,
retail sales and market share) which will affect  future  earnings and which the
Large-Cap Series believes are the primary factors  determining the future market
valuation of stocks.  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.  There can be no assurance  that stocks  selected for our portfolio  will
appreciate in value or that their dividends will increase or be maintained.

In selecting  securities for investment,  the Large-Cap Series gives more weight
to the  possibilities  of capital  growth  and growth of income  than to current
income.  In seeking to fulfill our objective,  we will invest also in both small
and middle-sized  companies, as measured by the value of their outstanding stock
guided by the  policies  mentioned  herein.  Stock  prices  of such  small-sized
companies may be more volatile than those of large- and middle-sized companies.

By  concentrating  our  research  and  stock  selection  on  companies  that are
undervalued  or  out of  current  investment  favor,  our  investment  portfolio
typically    will    encompass   less   market   risk   as   measured   by   its
price-to-normal-earnings  and price-to-book-value  ratios. The Large-Cap Series'
management  process results in the sale of stocks that we judge to be overpriced
and  reinvestment  in other  securities  that we believe offer better values and
less market risk.

The  Large-Cap  Series'  investment  portfolio  will be  diversified  among many
issuers  representing  many  different  industries.  The portfolio  reflects the
collective  judgment of the Research  Department  of Lord,  Abbett & Co.  ("Lord
Abbett")  as  to  what  securities  represent  the  greatest  investment  value,
regardless  of  industry   sector,   market   capitalization,   or  Wall  Street
sponsorship. At the time of purchase,  securities selected for our portfolio may
be largely  neglected by the investment  community or, if widely followed,  they
may be out of favor or at least controversial.

Up to 10% of the Large-Cap Series' net assets (at the time of investment) may be
invested in foreign  securities (of the type described  herein) primarily traded
in foreign countries.

We may write covered call options for  securities in our portfolio with a market
value of up to 5% of our gross  assets at the time an option is written.  We may
use these  options,  which are  traded on a  national  securities  exchange,  to
increase our income and to provide greater flexibility in the disposition of our
portfolio securities.

The  Large-Cap  Series may  engage in (a)  lending of  portfolio  securities  to
broker-dealers  on a secured  basis and (b)  investing in rights and warrants to
purchase  securities.  The Large--Cap  Series has no present intention to commit
more than 5% of its gross assets to any one of these two  identified  practices.
The term  "warrants"  includes  warrants which are not listed on the New York or
American  Stock  Exchanges.  Such  unlisted  warrants  may not  exceed 2% of the
Large-Cap Series' assets.

The Large-Cap Series may invest in closed-end  investment companies if bought in
the  secondary  market with a fee or  commission  no greater than the  customary
broker's  commission  in  compliance  with the  Investment  Company Act of 1940.
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 we and the closed-end investment company both charge
a management fee.

The Large-Cap Series may deal in financial futures  transactions with respect to
the type of securities  described  herein,  including indices of such securities
and options on such financial futures.  The Large-Cap 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.

Small-Cap Series.  The Small-Cap Series will attempt to achieve its objective by
investing primarily in a carefully selected portfolio of common stocks. Dividend
and investment income is of incidental importance,  and the Small-Cap Series may
invest in  securities  which do not produce any income.  Although the  Small-Cap
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  Small-Cap  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 Small-Cap  Series' portfolio if they are
expected to help it attain its  objective.  These criteria can be changed by the
Fund's Board of Directors.


<PAGE>

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 Small-Cap 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 "Hedging and
Income Enhancement Strategies" below.

In seeking to achieve its investment  objective,  the Small-Cap Series generally
will invest in common stocks with smaller market  capitalizations  than those of
the stocks included in the Dow Jones Industrial  Average or the Composite Index.
As a result, under normal  circumstances,  at least 65% of the Small-Cap 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 Small-Cap Series
may,  however,  invest up to 35% of its total  assets in the  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.

HEDGING AND INCOME ENHANCEMENT STRATEGIES.  The Small-Cap Series also may engage
in various portfolio strategies,  to reduce certain risks of its investments and
to attempt to enhance income, but not for speculation.  These strategies include
the  purchase  and sale of put and call  options,  and the  purchase and sale of
stock index futures and strategy  combinations.  Fund  management  will use such
techniques as market  conditions  warrant.  The Small-Cap Series' ability to use
these strategies may be limited by market conditions, regulatory limitations and
tax  considerations  and there can be no assurance that any of these  strategies
will  succeed.  See  "Investment  Objective  and  Policies" in the  Statement of
Additional  Information.  New financial products and risk management  techniques
continue to be developed and the Small-Cap  Series may use these new investments
and  techniques  to the extent  consistent  with its  investment  objective  and
policies.

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  Small-Cap  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 Small-Cap 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  Small-Cap  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  Objective  and Policies -- Limitation on Purchase and Sale 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  Small-Cap  Series may only write  covered put options to the extent
that cover for such  options  does not exceed 25% of the  Small-Cap  Series' net
assets. The Small-Cap 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  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.
In  addition,  except in the case of a call  written and held on the same index,
the  Small-Cap  Series  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 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 Small-Cap Series' net assets.


<PAGE>



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
are primarily traded in foreign countries. See "Risk Factors" below.

FOREIGN  CURRENCY HEDGING  TECHNIQUES.  The Small-Cap Series may utilize various
foreign currency hedging techniques described below.

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  Small-Cap
Series may enter into  forward  foreign  currency  contracts  in  primarily  two
circumstances.  First,  when the Small-Cap  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 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
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 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 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.

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 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. The premiums paid for such foreign currency
put options will not exceed 5% of the net assets of the Small-Cap Series.

Unlisted options, together with other illiquid securities,  may comprise no more
than 15% of the Small-Cap Series' net assets.

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 Small-Cap
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  or  cross-hedging
(described above) may not exceed 90% of the value of the securities  denominated
in such  currency  (a)  invested in by the  Small-Cap  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 Small-Cap  Series  assets,  may be warrants which are not listed on
the New York or  American  Stock  Exchanges),  but the  Small-Cap  Series has no
present  intention  to commit  more than 5% of gross  assets to any one of these
four identified practices.  The Small-Cap 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.

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  Small-Cap
Series' money is invested in the  security.  The  Small-Cap  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 Small-Cap Series will require additional
collateral.  If the seller defaults and the value of the collateral securing the
repurchase agreement declines, the Small-Cap Series may incur a loss.

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  Small-Cap  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 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 Small-Cap  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.


<PAGE>



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"),  and  that  not  more  than  25% of the  Series'  net  assets
(determined  at the time of the short sale) may be subject to such sales.  Short
sales will be made  primarily to defer  realization  of gain or loss for federal
tax purposes.  The Small-Cap  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 Small-Cap 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  Small-Cap  Series of an amount
designed to reflect the counterparty's  economic loss from an early termination,
but does allow the Series to treat the assets used as "cover" as "liquid."

The  Small-Cap  Series  will  not  change  its  investment   objective   without
shareholder  approval.  If the Series  determines that its objective can best be
achieved by a substantive change in investment policy or strategy, the Small-Cap
Series may make such a change without  shareholder  approval by disclosing it in
the prospectus.

OTHER  POLICIES  COMMON TO BOTH SERIES.  Each Series may invest up to 15% of its
net assets in illiquid securities.  Securities determined by the Directors to be
liquid  pursuant to Securities  and Exchange  Commission  Rule 144A (the "Rule")
will not be subject to this limit. Investments in Rule 144A securities initially
determined  to be liquid  could  have the effect of  diminishing  the level of a
Series'   liquidity   during  periods  of  decreased  market  interest  in  such
securities.  Under the Rule, a qualifying unregistered security may be resold to
a qualified  institutional  buyer  without  registration  and without  regard to
whether the seller originally purchased the security for investment.

Each  Series  will  not  borrow  money,   except  as  a  temporary  measure  for
extraordinary  or  emergency  purposes and then not in excess of 5% of its gross
assets at the lower of cost or market value.

For temporary  defensive  purposes or to create reserve purchasing power pending
other  investments,  each  Series may invest in  high-quality,  short-term  debt
obligations of banks,  corporations or the U.S.  Government of the type normally
owned by a money market fund. Neither an issuer's ceasing to be rated investment
grade nor a rating reduction below that grade will require elimination of a bond
from our portfolios.

RISK FACTORS.  If a Series remains small, there is risk that redemptions may (a)
cause portfolio  securities to be sold prematurely (at a loss or gain, depending
upon the  circumstances)  or (b)  hamper  or  prevent a  contemplated  portfolio
security  purchase.  Securities  markets  of foreign  countries  in which we 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.
There may be less publicly-available  information on publicly-traded  companies,
banks and  governments in foreign  countries than generally is 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.  Other  considerations  include  political  and  social  instability,
expropriation,  higher transaction  costs,  currency  fluctuations,  withholding
taxes that cannot be passed through as a tax credit or reduction to shareholders
and different securities settlement practices.  Foreign securities may be traded
on days that we do not value our portfolio  securities,  and,  accordingly,  net
asset values may be significantly affected on days when shareholders do not have
access to a Series.

Under normal circumstances,  each Series will invest primarily in common stocks,
and/or  securities  convertible  into common stocks,  which subjects a Series to
market risk, that is, the possibility that common stock prices will decline over
short or even extended periods.

RISK FACTOR UNIQUE TO THE SMALL-CAP  SERIES.  Although the Small-Cap  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 Hedging and Income Enhancement Strategies. 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
Small-Cap  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 Objective and Policies" and
"Taxes" in the Statement of Additional Information.

PORTFOLIO  TURNOVER.  The  Portfolio  turnover  rate for the  fiscal  year ended
November 30, 1996 for the Large-Cap Series was 62.25% compared to 37.17% for the
prior fiscal year. For the period December 13, 1995 (commencement of operations)
to November 30, 1996, the Small-Cap Series' portfolio turnover rate was 110.09%.

5    PURCHASES

ALTERNATIVE SALES ARRANGEMENTS

CLASSES OF SHARES.  Each Series  offers  investors  three  different  classes of
shares.  The  different  classes  of shares  represent  investments  in the same
portfolio of  securities  but are subject to different  expenses and will likely
have different  share prices.  Investors  should read this section  carefully to
determine which class represents the best investment option for their particular
situation.

CLASS A SHARES.  If you buy Class A shares,  you pay an initial  sales charge on
investments  of less than $1 million (or on investments  for  employer-sponsored
retirement  plans under the Internal  Revenue Code  (hereinafter  referred to as
"Retirement Plans") with less than 100 eligible employees. If you purchase Class
A shares as part of an  investment  of at least $1  million  (or for  Retirement
Plans  with at least  100  eligible  employees),  in  shares of one or more Lord
Abbett-sponsored  funds,  you will not pay an initial sales  charge,  but if you
redeem  any of those  shares  within 24 months  after the month in which you buy
them, you may pay to the Fund a contingent deferred sales charge ("CDSC") of 1%.
Class A shares are subject to service and  distribution  fees that are currently
estimated  to total  annually  approximately  0.25 of 1% of the annual net asset
value of the Class A shares.  The initial sales charge  rates,  the CDSC and the
Rule 12b-1 plan  applicable to the Class A shares are described in "Buying Class
A Shares" below.

CLASS B SHARES.  If you buy Class B shares,  you pay no sales charge at the time
of  purchase,  but if you redeem your  shares  before the sixth  anniversary  of
buying them, you will normally pay a CDSC to Lord Abbett  Distributor LLC ("Lord
Abbett  Distributor").  That CDSC varies  depending  on how long you own shares.
Class B shares are subject to service and distribution fees at an annual rate of
1% of the  annual net asset  value of the Class B shares.  The CDSC and the Rule
12b-1 plan  applicable  to the Class B shares are  described in "Buying  Class B
Shares" below.

CLASS C SHARES.  If you buy Class C shares,  you pay no sales charge at the time
of  purchase,  but if you redeem your  shares  before the first  anniversary  of
buying  them,  you will  normally  pay the Fund a CDSC of 1%. Class C shares are
subject to service and  distribution  fees at an annual rate of 1% of the annual
net  asset  value of the  Class C  shares.  The CDSC  and the  Rule  12b-1  plan
applicable to the C shares are described in "Buying Class C Shares" below.

WHICH  CLASS OF SHARES  SHOULD YOU  CHOOSE?  Once you decide that a Series is an
appropriate  investment  for you,  the  decision  as to which class of shares is
better  suited to your  needs  depends  on a number of  factors  that you should
discuss with your financial adviser.  Class-specific  expenses and the effect of
the  different  types of sales  charges  on your  investment  will  affect  your
investment  results over time. The most important  factors are how much you plan
to  invest  and how long you plan to hold  your  investment.  If your  goals and
objectives  change over time and you plan to  purchase  additional  shares,  you
should  re-evaluate those factors to see if you should consider another class of
shares.

In the following discussion, to help provide you and your financial adviser with
a framework in which to choose a class,  we have made some  assumptions  using a
hypothetical  investment in a Series.  We used the sales charge rates that apply
to Class  A,  Class B and  Class C, and  considered  the  effect  of the  higher
distribution  fees on Class B and  Class C  expenses  (which  will  affect  your
investment  return). Of course, the actual performance of your investment cannot
be predicted and will vary, based on a Series' actual  investment  returns,  the
operating  expenses  borne by each class of shares,  and the class of shares you
purchase.  The factors briefly discussed below are not intended to be investment
advice,  guidelines  or  recommendations,   because  each  investor's  financial
considerations are different. The discussion below of the factors to consider in
purchasing a particular  class of shares assumes that you will purchase only one
class of shares and not a combination of shares of different classes.

HOW LONG DO YOU EXPECT TO HOLD YOUR  INVESTMENT?  While future  financial  needs
cannot be  predicted  with  certainty,  knowing how long you expect to hold your
investment  will assist you in selecting the  appropriate  class of shares.  For
example,  over time, the reduced sales charges available for larger purchases of
Class A shares may offset the effect of paying an initial  sales  charge on your
investment,  compared to the effect over time of higher class-specific  expenses
on Class B or Class C shares for which no initial sales charge is paid.  Because
of the effect of  class-based  expenses,  your choice  should also depend on how
much you plan to invest.

Investing for the Short Term. If you have a short-term  investment horizon (that
is,  you plan to hold your  shares  for not more  than six  years),  you  should
probably  consider  purchasing  Class A or Class C shares  rather  than  Class B
shares.  This is because of the effect of the Class B CDSC if you redeem  before
the sixth  anniversary  of your  purchase,  as well as the effect of the Class B
distribution  fee on the  investment  return for that  class in the short  term.
Class C shares might be the  appropriate  choice  (especially for investments of
less than $100,000), because there is no initial sales charge on Class C shares,
and the CDSC does not apply to amounts you redeem after holding them one year.


<PAGE>



However,  if you plan to invest more than $100,000 for the short term,  then the
more you invest and the more your investment horizon increases toward six years,
the more  attractive  the Class A share  option may become.  This is because the
annual  distribution  fee on Class C shares  will have a greater  impact on your
account over the longer term than the reduced  front-end sales charge  available
for  larger  purchases  of Class A shares.  For  example,  Class A might be more
appropriate  than Class C for  investments of more than $100,000 that you expect
to hold for 5 or 6 years (or  more).  For  investments  over  $250,000  that you
expect  to  hold 4 to 6  years  (or  more),  Class  A  shares  may  become  more
appropriate  than Class C. If you are  investing  $500,000 or more,  Class A may
become more desirable as your investment horizon approaches 3 years or more.

For most investors who invest $1 million or more or for Retirement Plans with at
least 100  eligible  employees,  in most cases  Class A shares  will be the most
advantageous choice, no matter how long you intend to hold your shares. For that
reason, Lord Abbett Distributor normally will not accept purchase orders (i) for
Class B shares of $500,000 or more and for Class C shares of  $1,000,000 or more
from a single investor or (ii) for Class B or C shares for Retirement Plans with
at least 100 eligible employees.

Investing  for the Longer Term.  If you are  investing  for the longer term (for
example,  to provide  for future  college  expenses  for your  child) and do not
expect to need access to your money for seven years or more,  Class B shares may
be an appropriate  investment  option, if you plan to invest less than $100,000.
If you plan to invest more than $100,000 over the long term, Class A shares will
likely be more  advantageous than Class B shares or Class C shares, as discussed
above,  because of the effect of the expected  lower expenses for Class A shares
and the reduced initial sales charges available for larger  investments in Class
A shares under the Fund's Rights of Accumulation.

Of course,  these examples are based on  approximations of the effect of current
sales charges and expenses on a  hypothetical  investment  over time, and should
not be relied on as rigid guidelines.

ARE THERE  DIFFERENCES  IN ACCOUNT  FEATURES  THAT MATTER TO YOU?  Some  account
features  are  available  in whole or in part to  Class A,  Class B and  Class C
shareholders.  Other features (such as Systematic Withdrawal Plans) might not be
advisable in non-Retirement  Plan accounts for Class B shareholders  (because of
the effect of the CDSC on the entire  amount of a  withdrawal  if it exceeds 12%
annually) and in any account for Class C  shareholders  during the first year of
share  ownership  (due  to the  CDSC  on  withdrawals  during  that  year).  See
"Systematic  Withdrawal Plan" under "Shareholder  Services" for more information
about the 12% annual  waiver of the CDSC.  You should  carefully  review how you
plan to use your  investment  account before  deciding which class of shares you
buy. For example, the dividends payable to Class B and Class C shareholders will
be reduced by the expenses  borne solely by each of these  classes,  such as the
higher  distribution  fee to which  Class B and Class C shares are  subject,  as
described below.

HOW DOES IT AFFECT PAYMENTS TO MY BROKER?  A salesperson,  such as a broker,  or
any other person who is entitled to receive compensation for selling Fund shares
may  receive  different  compensation  for  selling  one class than for  selling
another class. As discussed in more detail below, such compensation is primarily
paid at the time of sale in the case of  Class A and B shares  and is paid  over
time, so long as shares remain outstanding, in the case of Class C shares. It is
important that investors understand that the primary purpose of the CDSC for the
Class B shares  and the  distribution  fee for Class B and Class C shares is the
same as the purpose of the front-end sales charge on sales of Class A shares: to
compensate  brokers and other persons selling such shares. The CDSC, if payable,
supplements  the Class B  distribution  fee and reduces the Class C distribution
fee expenses for a Series and Class C shareholders.

GENERAL

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 Lord Abbett  Research  Fund,  Inc. (P.O.  Box 419100,  Kansas City,  Missouri
64141).   The  minimum  initial  investment  is  $1,000  except  for  Individual
Retirement   Accounts,   Invest-A-Matic  and  Div-Move  ($250  initial  and  $50
subsequent  minimum  for  the  latter  two).  See  "Shareholder  Services."  For
information  regarding the proper form of a purchase or redemption  order,  call
the Fund at 800-821-5129.  This offering may be suspended, changed or withdrawn.
Lord Abbett Distributor reserves the right to reject any order.

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.

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 the  applicable  public  offering  price  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 applicable  public  offering price 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.

Lord Abbett Distributor may, for specified periods,  allow dealers to retain the
full sales charge for sales of shares during such periods,  or pay an additional
concession to a dealer who,  during a specified  period,  sells a minimum dollar
amount of our shares and/or shares of other Lord Abbett-sponsored funds. In some
instances,  such additional  concessions will be offered only to certain dealers
expected to sell  significant  amounts of shares.  Lord Abbett  Distributor may,
from time to time, implement promotions under which Lord Abbett Distributor will
pay a fee to dealers with respect to certain purchases not involving  imposition
of  a  sales  charge.   Additional   payments  may  be  paid  from  Lord  Abbett
Distributor's  own  resources  and  will  be made in the  form  of cash  or,  if
permitted,  non-cash  payments.  The non-cash  payments  will  include  business
seminars at resorts or other locations,  including meals and  entertainment,  or
the receipt of  merchandise.  The cash payments will include  payment of various
business  expenses  of the dealer.  In  selecting  dealers to execute  portfolio
transactions  for the Fund's  portfolio,  if two or more dealers are  considered
capable of obtaining best  execution,  we may prefer the dealer who has sold our
shares and/or shares of other Lord Abbett-sponsored funds.

CLASS A SHARE VOLUME  DISCOUNTS.  This section describes several ways to qualify
for a lower  sales  charge  when  purchasing  Class A shares if you inform  Lord
Abbett  Distributor  or the Fund that you are  eligible at the time of purchase.
(1) Any purchaser (as described below) may aggregate a Class A share purchase in
the Fund with any share  purchases of any other  eligible Lord  Abbett-sponsored
fund, together with the current value at maximum offering price of any shares in
the Fund and in any eligible Lord Abbett-sponsored  funds held by the purchaser.
(Holdings  in the  following  funds are not  eligible  for the  above  rights of
accumulation:  Lord  Abbett  Equity  Fund  ("LAEF"),  Lord  Abbett  Series  Fund
("LASF"),  any series of Lord  Abbett  Research  Fund not offered to the general
public  ("LARF") and Lord Abbett U.S.  Government  Securities  Money Market Fund
("GSMMF"),  except for  holdings in GSMMF which are  attributable  to any shares
exchanged  from  a Lord  Abbett-sponsored  fund.)  (2) A  purchaser  may  sign a
non-binding  13-month  statement of  intention to invest  $50,000 or more in any
shares  of the  Fund or in any of the  above  eligible  funds.  If the  intended
purchases  are  completed  during the period,  the total amount of your intended
purchases  of any shares will  determine  the reduced  sales charge rate for the
Class A shares purchased during the period. If not completed, each Class A share
purchase  will be at the sales  charge for the  aggregate  of the  actual  share
purchases. Shares issued upon reinvestment of dividends or distributions are not
included in the statement of  intention.  The term  "purchaser"  includes (i) an
individual,  (ii) an individual and his or her spouse and children under the age
of 21 and (iii) a trustee  or other  fiduciary  purchasing  shares  for a single
trust estate or single fiduciary account  (including a pension,  profit-sharing,
or other  employee  benefit  trust  qualified  under Section 401 of the Internal
Revenue  Code -- more  than one  qualified  employee  benefit  trust of a single
employer,  including its consolidated  subsidiaries,  may be considered a single
trust, as may qualified plans of multiple employers  registered in the name of a
single bank  trustee as one  account),  although  more than one  beneficiary  is
involved.

CLASS A NET ASSET VALUE  PURCHASES.  Our Class A shares may be  purchased at net
asset  value  by our  directors,  employees  of Lord  Abbett,  employees  of our
shareholder  servicing  agent and  employees of any  securities  dealer having a
sales  agreement with Lord Abbett  Distributor who consents to such purchases or
by the trustee or custodian under any pension or profit-sharing  plan or Payroll
Deduction IRA  established for the benefit of such persons or for the benefit of
any national  securities trade  organization to which Lord Abbett or Lord Abbett
Distributor  belongs or any company with an  account(s) in excess of $10 million
managed by Lord Abbett on a private-advisory-account basis. For purposes of this
paragraph,  the  terms  "directors"  and  "employees"  include a  director's  or
employee's  spouse  (including  the surviving  spouse of a deceased  director or
employee).  The terms  "directors"  and  "employees of Lord Abbett" also include
other family  members and retired  directors and  employees.  Our Class A shares
also may be  purchased  at net asset  value (a) at $1 million or more,  (b) with
dividends  and  distributions  on Class A shares of other Lord  Abbett-sponsored
funds,  except for dividends and distributions on shares of LARF, LAEF and LASF,
(c) under the loan feature of the Lord  Abbett-sponsored  prototype  403(b) plan
for  Class A  share  purchases  representing  the  repayment  of  principal  and
interest,  (d) by 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 A shares in
particular  investment  products  made  available  for a fee to  clients of such
brokers,   dealers,   registered   investment   advisers  and  other   financial
institutions ("mutual fund wrap fee programs"),  (e) by employees,  partners and
owners of  unaffiliated  consultants  and advisers to Lord  Abbett,  Lord Abbett
Distributor or Lord Abbett-sponsored  funds who consent to such purchase if such
persons provide services to Lord Abbett,  Lord Abbett  Distributor or such funds
on a continuing  basis and are familiar with such fund,  (f) through  Retirement
Plans with at least 100  eligible  employees,  and (g)  subject  to  appropriate
documentation,  through a securities dealer where the amount invested represents
redemption  proceeds from shares  ("Redeemed  Shares") of a registered  open-end
management  investment  company  not  distributed  or  managed  by  Lord  Abbett
Distributor or Lord Abbett (other than a money market fund), if such redemptions
have  occurred no more than 60 days prior to the purchase of our Class A shares,
the Redeemed  Shares were held for at least six months prior to  redemption  and
the proceeds of redemption  were maintained in cash or a money market fund prior
to  purchase.  Purchasers  should  consider  the impact,  if any, of  contingent
deferred  sales charges in  determining  whether to redeem shares for subsequent
investment  in our  Class A shares.  Lord  Abbett  Distributor  may  suspend  or
terminate the purchase  option  referred to in (g) above at any time. We plan to
terminate the net asset value transfer privilege on June 1, 1997.


<PAGE>



CLASS A RULE 12B-1 PLAN. The Fund has adopted a Class A share Rule 12b-1 plan on
behalf of each Series (the "A Plans",  each, an "A Plan") which  authorizes  the
payment of fees to authorized  institutions  (except as to certain  accounts for
which tracking data is not available) in order to provide additional  incentives
for them (a) to provide continuing  information and investment services to their
Class A shareholder accounts and otherwise to encourage those accounts to remain
invested in the Series and (b) to sell Class A shares of the Series. Under the A
Plan, in order to save on the expense of  shareholders'  meetings and to provide
flexibility  to the Board of Directors,  the Board,  including a majority of the
outside directors who are not "interested persons" of the Fund as defined in the
Investment  Company Act of 1940, is  authorized  to approve  annual fee payments
from a Series' Class A assets of up to 0.50 of 1% of the average net asset value
of such assets  consisting of  distribution  and service fees, each at a maximum
annual rate not exceeding 0.25 of 1% (the "Fee Ceiling").

Under the A Plans,  the Board has  approved  payments by the Fund to Lord Abbett
Distributor  which uses or passes on to  authorized  institutions  (1) an annual
service fee (payable  quarterly) of .25% of the average daily net asset value of
the  Class A shares  serviced  by  authorized  institutions  and (2) a  one-time
distribution fee of up to 1% (reduced according to the following schedule: 1% of
the first $5 million,  .55% of the next $5 million, .50% of the next $40 million
and .25% over $50  million),  payable  at the time of sale on all Class A shares
sold during any  12-month  period  starting  from the day of the first net asset
value sale (i) at the $1 million  level by  authorized  institutions,  including
sales qualifying at such level under the rights of accumulation and statement of
intention privileges or (ii) through Retirement Plans with at least 100 eligible
employees. In addition, the Board has approved for those authorized institutions
which qualify,  a  supplemental  annual  distribution  fee equal to 0.10% of the
average  daily net  asset  value of the Class A shares  serviced  by  authorized
institutions  that have a satisfactory  program for the promotion of such shares
comprising a  significant  percentage  of the Class A assets,  with a lower than
average  redemption rate.  Institutions and persons  permitted by law to receive
such fees are "authorized institutions".

Under the A Plans, Lord Abbett Distributor is permitted to use payments received
to provide continuing  services to Class A shareholder  accounts not serviced by
authorized  institutions and, with Board approval, to finance any activity which
is primarily intended to result in the sale of Class A shares. Any such payments
are subject to the Fee Ceiling.  Any  payments  under that Plan not used by Lord
Abbett Distributor in this manner are passed on to authorized institutions.

Holders of Class A shares on which the 1% sales  distribution  fee has been paid
may be  required to pay such Series on behalf of its Class A shares a CDSC of 1%
of the  original  cost or the then net asset value,  whichever  is less,  of all
Class A shares so purchased which are redeemed out of the Lord  Abbett-sponsored
family of funds on or before the end of the twenty-fourth  month after the month
in  which  the  purchase  occurred.  (Exceptions  are made  for  redemptions  by
Retirement  Plans  due to any  benefit  payment  such  as Plan  loans,  hardship
withdrawals,  death,  retirement or separation from service with respect to plan
participants or the  distribution of any excess  contributions.)  If the Class A
shares have been  exchanged  into  another  Lord  Abbett-sponsored  fund and are
thereafter  redeemed out of the Lord Abbett family of funds on or before the end
of such twenty-fourth  month, the charge will be collected for the Series' Class
A shares by the other fund. The Series will collect such a charge for other Lord
Abbett-sponsored funds in a similar situation.

BUYING  CLASS B SHARES.  Class B shares  are sold at net  asset  value per share
without an initial  sales  charge.  However,  if Class B shares are redeemed for
cash before the sixth anniversary of their purchase, a CDSC may be deducted from
the redemption proceeds. That sales charge will not apply to shares purchased by
the reinvestment of dividends or capital gains distributions. The charge will be
assessed  on the  lesser  of the net  asset  value of the  shares at the time of
redemption  or the  original  purchase  price.  The Class B CDSC is paid to Lord
Abbett Distributor to compensate it for its services rendered in connection with
the distribution of Class B shares, including the payment and financing of sales
commissions. See "Class B Rule 12b-1 Plan" below.

To determine  whether the CDSC applies to a redemption,  the Fund redeems shares
in the following  order:  (1) shares  acquired by  reinvestment of dividends and
capital  gains  distributions,  (2) shares held until the sixth  anniversary  of
their  purchase  or later,  and (3)  shares  held the  longest  before the sixth
anniversary of their purchase.

The amount of the CDSC will depend on the number of years since you invested and
the dollar amount being redeemed, according to the following schedule.

In the table,  an  "anniversary"  is the 365th day subsequent to a purchase or a
prior  anniversary.  All  purchases  are  considered  to have  been  made on the
business  day the  purchase was made.  See "Buying  Shares  Through Your Dealer"
above.


<PAGE>



If  Class  B  shares  are  exchanged   into  the  same  class  of  another  Lord
Abbett-sponsored  fund and the new shares  are  subsequently  redeemed  for cash
before the sixth anniversary of the original purchase,  the CDSC will be payable
on the new shares on the basis of the time elapsed  from the original  purchase.
The Series will collect such a charge for other Lord Abbett-sponsored funds in a
similar situation.

WAIVER OF CLASS B SALES CHARGES.  The Class B CDSC will not be applied to shares
purchased in certain types of transactions  nor will it apply to shares redeemed
in certain circumstances as described below. The Class B CDSC will be waived for
redemptions of shares (i) in connection with the Systematic  Withdrawal Plan and
Div-Move  services,  as described in more detail  under  "Shareholder  Services"
below,  (ii) by Retirement  Plans due to any benefit payment such as Plan loans,
hardship withdrawals,  death, retirement or separation from service with respect
to plan participants or the distribution of any excess  contributions,  (iii) in
connection  with  mandatory  distributions  under  403(b)  plans and  individual
retirement accounts and (iv) in connection with the death of the shareholder.

CLASS B 12B-1  PLAN.  The Fund has  adopted a Class B share  Rule  12b-1 plan on
behalf of each Series (the "B Plans",  each a "B Plan")  under which each Series
periodically  pays Lord Abbett  Distributor (i) an annual service fee of 0.25 of
1% of the average daily net asset value of the Class B shares and (ii) an annual
distribution  fee of 0.75 of 1% of the average  daily net asset value of Class B
shares that are outstanding for less than 8 years.

Lord  Abbett   Distributor  uses  the  service  fee  to  compensate   authorized
institutions  for  providing  personal  services for accounts  that hold Class B
shares. Those services are primarily similar to those provided under the A Plan,
described above.

Lord Abbett  Distributor  pays an up-front  payment to  authorized  institutions
totalling 4%,  consisting of 0.25% for service and 3.75% for a sales  commission
as described below.

Lord Abbett Distributor pays the 0.25% service fee to authorized institutions in
advance for the first year after Class B shares have been sold by the authorized
institutions.  After  the  shares  have  been  held  for  a  year,  Lord  Abbett
Distributor pays the service fee on a quarterly basis.  Lord Abbett  Distributor
is entitled to retain such service fee payable under the B Plans with respect to
accounts  for which there is no  authorized  institution  of record or for which
such authorized  institution  did not qualify.  Although not obligated to do so,
Lord Abbett  Distributor may waive receipt from the Series or part of all of the
service fee payments.

The  0.75%  annual  distribution  fee is  paid  to Lord  Abbett  Distributor  to
compensate it for its services  rendered in connection with the  distribution of
Class B shares,  including  the  payment  and  financing  of sales  commissions.
Although Class B shares are sold without a front-end  sales charge,  Lord Abbett
Distributor pays authorized institutions responsible for sales of Class B shares
a sales  commission of 3.75% of the purchase price.  This payment is made at the
time of sale from Lord Abbett Distributor's own resources.  Lord Abbett has made
arrangements to finance these commission  payments,  which arrangements  include
non-recourse  assignments by Lord Abbett  Distributor to the financing  party of
such distribution and CDSC payments which are made to Lord Abbett Distributor by
shareholders who redeem their Class B shares within six years of their purchase.

The  distribution  fee and CDSC payments  described above allow investors to buy
Class B shares  without a front-end  sales  charge  while  allowing  Lord Abbett
Distributor to compensate authorized  institutions that sell Class B shares. The
CDSC is intended to supplement Lord Abbett  Distributor's  reimbursement for the
commission  payments it has made with  respect to Class B shares and its related
distribution  and financing  costs. The distribution fee payments are at a fixed
rate and the CDSC payments are of a nature that,  during any year, both forms of
payment may not be  sufficient  to  reimburse  Lord Abbett  Distributor  for its
actual  expenses.  Neither  Series is liable for any  expenses  incurred by Lord
Abbett Distributor in excess of (i) the amount of such distribution fee payments
to be received by Lord Abbett  Distributor  and (ii)  unreimbursed  distribution
expenses of Lord Abbett  Distributor  incurred in a prior plan year,  subject to
the right of the Board of Directors or  shareholders to terminate a B Plan. Over
the long term, the expenses incurred by Lord Abbett Distributor are likely to be
greater than such distribution fee and CDSC payments. Nevertheless, there exists
a possibility that for a short-term period Lord Abbett  Distributor may not have
sufficient expenses to warrant reimbursement by receipt of such distribution fee
payments. Although Lord Abbett Distributor undertakes not to make a profit under
the B Plans, a B Plan is considered a compensation plan (i.e., distribution fees
are paid  regardless of expenses  incurred) in order to avoid the possibility of
Lord Abbett Distributor not being able to receive distribution fees because of a
temporary timing difference  between its incurring  expenses and receipt of such
distribution fees.

AUTOMATIC  CONVERSION  OF CLASS B  SHARES.  On the  eighth  anniversary  of your
purchase of Class B shares,  those shares will automatically  convert to Class A
shares.  This  conversion  relieves  Class B  shareholders  of the higher annual
distribution  fee that  applies  to Class B shares  under the Class B Rule 12b-1
Plan.  The  conversion  is based on the  relative  net  asset  values of the two
classes,  and no sales  charge or other  charge is imposed.  When Class B shares
convert,  any other Class B shares that were  acquired  by the  reinvestment  of
dividends  and  distributions  will also convert to Class A shares on a pro rata
basis.  The conversion  feature is subject to the continued  availability  of an
opinion of counsel or of a tax ruling  described in "Purchases,  Redemptions and
Shareholder Services" in the Statement of Additional Information.

BUYING  CLASS C SHARES.  Class C shares  are sold at net  asset  value per share
without an initial  sales  charge.  However,  if Class C shares are redeemed for
cash  before  the  first  anniversary  of their  purchase,  a CDSC of 1% will be
deducted from the redemption proceeds. That reimbursement charge


<PAGE>



will not apply to shares  purchased by the  reinvestment of dividends or capital
gains distributions.  The charge will be assessed on the lesser of the net asset
value of the shares at the time of  redemption or the original  purchase  price.
The Class C CDSC is paid to the appropriate  Series to reimburse it, in whole or
in part, for the service and distribution fee payments made by the Series at the
time such shares were sold, as described below.

To determine whether the CDSC applies to a redemption, the Series redeems shares
in the following  order:  (1) shares  acquired by  reinvestment of dividends and
capital gains distributions, (2) shares held for one year or more and (3) shares
held the longest  before the first  anniversary  of their  purchase.  If Class C
shares  are   exchanged   into  the  same  class  of  another   Series  or  Lord
Abbett-sponsored  fund and subsequently redeemed before the first anniversary of
their  original  purchase,  the charge will be  collected by the other Series or
fund on behalf of such  Series'  Class C shares.  The Series will collect such a
charge for other Lord Abbett-sponsored funds in a similar situation.

CLASS C 12B-1  PLAN.  The Fund has  adopted a Class C share  Rule  12b-1 Plan on
behalf of each Series (the "C Plans", each a "C Plan") under which (except as to
certain  accounts  for which  tracking  data is not  available)  the Series pays
authorized  institutions through Lord Abbett Distributor (1) a service fee and a
distribution  fee, at the time  shares are sold,  not to exceed 0.25 and 0.75 of
1%,  respectively,  of the  net  asset  value  of  such  shares  and (2) at each
quarter-end after the first anniversary of the sale of shares, fees for services
and distribution at annual rates not to exceed 0.25 and 0.75 of 1% respectively,
of the average annual net asset value of such shares outstanding  (payments with
respect to shares not outstanding during the full quarter to be prorated). These
service and distribution  fees are for purposes similar to those mentioned above
with  respect  to the A Plan.  Sales in clause  (1)  exclude  shares  issued for
reinvested  dividends and  distributions  and shares  outstanding  in clause (2)
include shares issued for reinvested dividends and distributions after the first
anniversary of their issuance.

6      SHAREHOLDER SERVICES

We offer the following shareholder services:
Telephone Exchange Privilege: Shares may be exchanged, without a service charge:
(a) for shares of the same class of any other Lord  Abbett-sponsored fund except
for (i) LAEF, LARF and LASF and (ii) certain tax-free  single-state series where
the exchanging  shareholder is a resident of a state in which such series is not
offered for sale and (b) for shares of any authorized  institution's  affiliated
money  market fund  satisfying  Lord Abbett  Distributor  as to certain  omnibus
account and other criteria (together, "Eligible Funds").

You or your representative  with proper  identification can instruct the Fund to
exchange  uncertificated  shares  (held by the  transfer  agent)  by  telephone.
Shareholders have this privilege unless they refuse it in writing. The 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 the Fund in Kansas  City  (800-821-5129)  prior to the close of the
NYSE to obtain  each  fund's  net asset  value per 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.  The Fund  reserves the right to
terminate  or  limit  the  privilege  of  any  shareholder  who  makes  frequent
exchanges.  The 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.

Systematic Withdrawal Plan ("SWP"):  Except for Retirement Plans for which there
is no such minimum,  if the maximum offering price value of your  uncertificated
shares is at least $10,000, you may have periodic cash withdrawals automatically
paid to you in either fixed or variable amounts. With respect to Class B shares,
the CDSC will be waived on  redemptions of up to 12% per year of the current net
asset  value of your  account at the time your SWP is  established.  For Class B
shares (over 12% per year) and C shares,  redemption  proceeds due to a SWP will
be derived from the following  sources in the order listed:  (1) shares acquired
by reinvestment of dividends and capital gains, (2) shares held for six years or
more  (Class B) or one year or more  (Class C); and (3) shares  held the longest
before the sixth  anniversary  of their  purchase  (Class B) or before the first
anniversary of their purchase (Class C). For Class B share  redemptions over 12%
per year,  the CDSC  will  apply to the  entire  redemption.  Therefore,  please
contact  the Fund  for  assistance  in  minimizing  the CDSC in this  situation.
Shareholders  should be careful in establishing a SWP,  especially to the extent
that such withdrawals exceed the annual total return for a class, in which case,
the  shareholder's  original  principal  will be invaded and, over time,  may be
depleted.

Div-Move:  You can  invest  the  dividends  paid on your  account  ($50  minimum
investment)  into an existing  account in any other  Eligible  Fund. The account
must be either your account,  a joint account for you and your spouse,  a single
account for your spouse,  or a custodial  account for your minor child under the
age of 21.  Such  dividends  are not  subject  to a CDSC.  You  should  read the
prospectus of the other fund before investing.

Invest-A-Matic:   You  can  make  fixed,   periodic   investments  ($50  minimum
investment)  into the Fund and/or any Eligible Fund by means of automatic  money
transfers from your bank checking account. You should read the prospectus of the
other fund before  investing.  Retirement Plans: Lord Abbett makes available the
retirement plan forms,  including 401(k) plans and custodial agreements for IRAs
(Individual  Retirement Accounts,  including Simple IRAs and Simplified Employee
Pensions), 403(b) plans and pension and profit-sharing plans.

Householding:  A single copy of an annual or semi-annual  report will be sent to
an address to which more than one  registered  shareholder  of the Fund with the
same last name has indicated mail is to be delivered,  unless additional reports
are specifically requested in writing or by telephone. All correspondence should
be directed to the Lord Abbett  Research Fund,  Inc.  (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  with the advice of Lord Abbett.  We employ
Lord Abbett as  investment  manager  pursuant to a  Management  Agreement.  Lord
Abbett has been an investment  manager for over 67 years and  currently  manages
approximately  $21  billion  in a family  of mutual  funds  and  other  advisory
accounts.  Under the Management  Agreement,  Lord Abbett  provides the Fund with
investment  management  services and  executive  and other  personnel,  pays the
remuneration  of our officers and of our directors  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
portfolio  and certain other costs.  Lord Abbett  provides  similar  services to
twelve other Lord  Abbett-sponsored  funds having various investment  objectives
and also  advises  other  investment  clients.  Robert G.  Morris,  Lord  Abbett
partner,  has been primarily  responsible for oversight of the Large-Cap  Series
since 1996,  although he has been  involved  with the Series'  management  since
inception.  Mr. Morris  delegates  management  duties to a committee of research
professionals. 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.

We are  obligated  to pay Lord Abbett a monthly  fee based on average  daily net
assets for each month at the annual  rate of .75%.  This fee may be higher  than
that paid by other mutual  funds.  For the fiscal year ended  November 30, 1996,
Lord Abbett waived  $40,304 in management  fees for the  Large-Cap  Series.  The
Class A share ratio of expenses,  including management fee expenses,  to average
net assets for the year ended  November  30, 1996 for the  Large-Cap  Series was
 .36%.  This Class A share expense ratio would have been .96% had Lord Abbett not
waived all or a portion of its management  fee. For the period December 13, 1995
(commencement of operations) to November 30, 1996, Lord Abbett waived $24,461 in
management fees for the Small-Cap  Series.  The Class A share ratio of expenses,
including  management  fee  expenses,  to average  net assets for the year ended
November 30, 1996 for the Small-Cap Series was .01% (not annualized). This Class
A share expense ratio would have been 1.00% (not annualized) had Lord Abbett not
waived all or a portion of its management fee.

THE FUND.  The Fund is a  diversified  open-end  management  investment  company
incorporated  under  Maryland law on April 6, 1992.  Its Class A, B and C shares
have equal rights as to voting,  dividends,  assets and  liquidation  except for
differences resulting from certain class-specific expenses.

8         DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES

Dividends from taxable net investment  income may be taken in cash or reinvested
in  additional  shares at net  asset  value  (without  a sales  charge)  and are
expected  to be paid to  shareholders  quarterly  for the  Large-Cap  Series and
annually for the Small-Cap  Series. If you elect a cash payment (i) a check will
be mailed to you as soon as possible after the monthly reinvestment date or (ii)
if you arrange for direct  deposit,  your payment will be wired directly to your
bank account within one day after the payable date.

A long-term  capital gains  distribution is made when we have net profits during
the year from sales of  securities  which we have held more than one year. If we
realize net short-term capital gains, they also will be distributed. Any capital
gains distributions are expected to be made in December and may be taken in cash
or reinvested in more shares at net asset value without a sales charge.

Dividends  and  distributions  declared in October,  November or December of any
year to  shareholders of record as of a date in such a month 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.

We intend to continue to meet the  requirements  of Subchapter M of the Internal
Revenue Code. We try to distribute  to  shareholders  all of our net  investment
income and net realized  capital gains, so as to avoid the necessity of the Fund
paying  federal income tax.  Shareholders,  however,  must report  dividends and
capital gains  distributions as taxable income.  Distributions  derived from net
long-term  capital  gains which are  designated  by the Fund as  "capital  gains
dividends" will be taxable to shareholders as long-term  capital gains,  whether
received  in cash or  shares,  regardless  of how long a  taxpayer  has held the
shares.  Under  current law, net  long-term  capital  gains of  individuals  and
corporations are taxed at the rates  applicable to ordinary income,  except that
the maximum rate for long-term capital gains for individuals is 28%. Legislation
has been proposed that would have the effect of reducing the federal  income tax
rate on capital gains.

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  proceeds  (including the value of shares  exchanged into another
Lord Abbett-sponsored fund), and of any dividend or distribution on any account,
where  the  payee   (shareholder)   failed   to   provide  a  correct   taxpayer
identification number or to make certain required certifications.


<PAGE>



We will  inform  shareholders  of the federal  tax status of each  dividend  and
distribution  after the end of each calendar year.  Shareholders  should consult
their tax advisers  concerning  applicable  state and local taxes as well as the
tax  consequences  of gains or losses  from the  redemption  or  exchange of our
shares.

9         REDEMPTIONS

To obtain the proceeds of an  expedited  redemption  of $50,000 or less,  you or
your representative with proper  identification can telephone the Fund. The 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.

If you do not qualify for the expedited redemption procedures described above to
redeem shares directly, send your request to the Lord Abbett Research Fund, Inc.
(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 proper form.  Payment will be made within three
days.  The Fund may suspend  the right to redeem  shares for not more than seven
days or longer under unusual  circumstances  as permitted by Federal law. If you
have  purchased  Fund  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.
Shares  also  may be  redeemed  by the  Fund at net  asset  value  through  your
securities dealer who, as an unaffiliated  dealer, may charge you a fee. If your
dealer receives your order prior to the close of the NYSE and communicates it to
Lord  Abbett  Distributor,  as our  agent,  prior to the  close  of Lord  Abbett
Distributor's business day, you will receive the net asset value as of the close
of the NYSE on that day.  If the dealer  does not  communicate  such an order to
Lord Abbett until the next business day, you will receive the net asset value as
of the close of the NYSE on that next business day.

Shareholders  who have redeemed  their shares have a one-time right to reinvest,
into another account having the identical  registration,  in any of the Eligible
Funds at the then  applicable net asset value (i) without the payment of a sales
charge or (ii) with reimbursement for the payment of any CDSC. Such reinvestment
must be made within 60 days of the redemption and is limited to no more than the
amount of the redemption proceeds.

Under certain  circumstances  and subject to 30 days' prior written notice,  our
Board of Directors may authorize  redemption of all of the shares in any account
in which there are fewer than 25 shares,  resulting from  redemption or exchange
not market action.

10        PERFORMANCE

The Fund  completed  its fiscal year on November  30, 1996 with net asset values
for the Class A and Class B shares of the Large-Cap Series of $17.86 and $17.83,
respectively. The net asset value for the Class A and B shares for the Small-Cap
Series were $12.01 and $12.00, respectively.

The strong  performance  the Large-Cap  Series enjoyed over the past fiscal year
can be  attributed  to  several  factors.  Overweighting  of  interest-sensitive
stocks,  particularly financial companies,  proved to be very beneficial.  These
stocks  increased  in value  toward the close of the fiscal  year,  as long-term
interest rates began to decline.  Additionally, the Series' holdings in consumer
non-cyclical stocks were steadily increased during the year and performed well.

The  Small-Cap  Series'  strong  performance  in 1996 can be attributed to three
sectors:  industrial,  technology  and  transportation.  The  technology  sector
experienced a third quarter  correction  which allowed us to add to positions at
attractive prices. The Small-Cap Series' industrial and transportation  holdings
were relatively steady  performers  throughout the year. The Small-Cap Series is
not sector  weighted  (diversified  in  proportion  to an index)  and,  as such,
continues to rely on stock  selection of undervalued  companies in the small-cap
universe with solid fundamental prospects.

TOTAL RETURN.  Total return for the one-, five- and ten-year periods  represents
the average annual  compounded  rate of return on an investment of $1,000 in the
Fund at the maximum public offering price. When total return is quoted for Class
A shares,  it includes the payment of the maximum  initial  sales  charge.  When
total  return is shown for Class B and C shares,  it reflects  the effect of the
applicable  CDSC.  Total return also may be presented for other periods or based
on investments at reduced sales charge levels or net asset value.  Any quotation
of total return not reflecting the maximum sales charge  (front-end,  level,  or
back-end)  would be reduced if such sales charge were used.  Quotations of 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  discussion  of the
computation of the Fund's total return.

LORD ABBETT

STATEMENT OF ADDITIONAL INFORMATION                                APRIL 1, 1997


                       LORD ABBETT RESEARCH FUND, INC
                              LARGE-CAP SERIES
                              SMALL-CAP SERIES


This Statement of Additional  Information is not a Prospectus.  A Prospectus for
Lord Abbett  Research  Fund,  Inc. (the "Fund"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 April 1, 1997.

Our Board of Directors  has  authority  to create and classify  shares of common
stock in separate  series,  without  further  action by  shareholders.  To date,
50,000,000 shares of the Large-Cap Series and 50,000,000 shares of the Small-Cap
Series have been  authorized at $0.001 par value.  Both Series  consist of three
classes  (A, B and C). The Class C shares for both Series will be offered to the
public for the first time on or about April 1, 1997. The Board of Directors will
allocate these  authorized  shares among the classes of each Series from time to
time.  All shares 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 in the future.  The Investment  Company Act of 1940,
as amended (the "Act"),  requires that where more than one series  exists,  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 the 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 the Fund or by
calling  800-821-5129.  In addition,  you can make inquiries through Lord Abbett
Distributor.

                              Investment Policies

FUNDAMENTAL INVESTMENT RESTRICTIONS
We are subject to the following investment  restrictions which cannot be changed
without  approval of the holders of a majority of our outstanding  shares.  Each
Series may not:  (1) borrow  money,  except that (i) each Series 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  Series  may  borrow up to an  additional  5% of its total  assets for
temporary  purposes,  (iii) each Series may obtain such short-term credit as may
be necessary for the  clearance of purchases  and sales of portfolio  securities
and (iv) each Series 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  Series'  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 Series 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  Series  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 Series 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  Series,  buy
securities  of one issuer  representing  more than (i) 5% of each Series'  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, we also
are subject to the following  non-fundamental  investment  policies which may be
changed by the Board of Directors without shareholder approval.  Each Series may
not:  (1)  borrow in excess  of 5% of its gross  assets  taken at cost or market
value, whichever is lower at the time of borrowing, 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
Board of Directors;  (4) invest in the securities of other investment  companies
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  Series'  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 of the 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 Series' total assets (included within such limitation, but not to exceed
2% of each Series'  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 Series
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
permitted

                                    2

in the Fund's prospectus and statement of additional information, as they may be
amended  from  time to  time;  or  (10)  buy  from or sell to any of the  Fund's
officers,  directors,  employees, or its investment adviser or any of the Fund's
officers,  directors, partners or employees, any securities other than shares of
the Funds' common stock.

For the fiscal year ended  November 30, 1996,  the  portfolio  turnover rate was
62.25% for the Large-Cap  Series  compared to 37.17% for the previous  year. For
the period December 13, 1995  (commencement of operations) to November 30, 1996,
the Small-Cap Series' portfolio turnover rate was 110.09%.

LENDING OF PORTFOLIO SECURITIES.  Although both Series 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 Series 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 we
will receive the income earned on investment of collateral.  The aggregate value
of the securities loaned will not exceed 5% of the value of either Series' gross
assets.

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

COVERED CALL OPTIONS.  As stated in the  Prospectus,  the  Large-Cap  Series may
write  covered  call  options on  securities  in our  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 a
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,  the Large-Cap  Series  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 our net
premium).   The  Large-Cap   Series  also  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 the Large-  Cap  Series is unable to enter into a closing  purchase
transaction,  it may be required to hold a security that it otherwise might have
sold to protect against  depreciation.  The Large-Cap  Series does not intend to
write covered call options with respect to securities  with an aggregate  market
value of more  than 5% of the  Series'  gross  assets  at the time an  option is
written.  This  percentage  limitation  will  not  be  increased  without  prior
disclosure in the Series' current prospectus.

RIGHTS AND WARRANTS.  The Large-Cap  Series may invest in rights and warrants to
purchase  securities.  Included within that amount,  but not to exceed 2% of the
value of the Large-Cap Series' net assets,  may be warrants which are not listed
on the NYSE or American Stock Exchange.

Rights represent a privilege  offered to holders of record of issued  securities
to subscribe (usually on a pro rata basis) for additional securities of the same
class,  of a  different  class  or of a  different  issuer,  as the case may be.
Warrants  represent the privilege to purchase  securities at a stipulated  price
and are usually valid for several  years.  Rights and warrants  generally do not
entitle a holder to  dividends or voting  rights with respect to the  underlying
securities  nor do they  represent  any  rights  in the  assets  of the  issuing
company.

Also, the value of a right or warrant may not necessarily  change with the value
of the underlying securities and rights and warrants cease to have value if they
are not exercised prior to their expiration date.

OPTIONS AND FINANCIAL FUTURES TRANSACTIONS

GENERAL.  The  Large-Cap  Series  may engage in options  and  financial  futures
transactions in accordance with the Large- Cap Series  investment  objective and
policies. Although the Large-Cap Series is not currently employing such options

                                       3

<PAGE>



and financial futures  transactions,  the Series may engage in such transactions
in the future if it appears advantageous to us to do so, in order to cushion the
effects of fluctuating interest rates and adverse market conditions.  The use of
options and financial  futures,  and possible  benefits and attendant risks, are
discussed  below,  along with  information  concerning  certain other investment
policies and techniques.

FINANCIAL FUTURES  CONTRACTS.  The Large-Cap 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  Large-Cap  Series hold or intend 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 Large-Cap  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 the Large-Cap Series outstanding  futures contracts
and securities  covered by futures contracts subject to the outstanding  options
written by us would exceed 50% of the Large-Cap Series 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 Large-Cap  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 our 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)  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 Large-Cap 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 Large-Cap
Series would be required to deposit with Series'  custodian  initial  margin and
maintenance  margin with  respect to put and call  options on futures  contracts
written by the Series. 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

                                       4

<PAGE>



amount were used to directly  purchase the same  financial  futures.  Should the
event it intends to hedge (or protect)  against not  materialize,  however,  the
option may expire  worthless,  in which case the Large-Cap Series would lose the
premium paid therefor.

SEGREGATED  ACCOUNTS.  To the extent  required  to comply  with  Securities  and
Exchange Commission Release 10666 and subsequent  interpretation  thereof by the
Commission or its staff,  when purchasing a futures  contract,  or writing a put
option,  the  Large-Cap  Series  will  maintain in a  segregated  account at its
custodian  bank  liquid  high  grade  debt  obligations,  such as cash  and U.S.
Government Securities to cover its position.

SMALL-CAP SERIES (ONLY)
OTHER 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
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

                                        5

<PAGE>



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.

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

                                         6

<PAGE>



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.

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

                                         7

<PAGE>



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.

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.

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

                                         8

<PAGE>



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  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

                                         9

<PAGE>



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.

1. Outside  directors' fees,  including  attendance fees for board and committee
meetings,  are  allocated  among all Lord  Abbett-sponsored  funds  based on net
assets of each fund.  A portion of the fees  payable by the Fund to its  outside
directors are being deferred under a plan that deems the deferred  amounts to be
invested  in shares of the Fund for later  distribution  to the  directors.  The
amounts of the  aggregate  compensation  payable by the Fund as of November  30,
1996, deemed invested in Fund shares, including dividends reinvested and changes
in net asset value  applicable to such deemed  investments,  were: Mr.  Bigelow,
$20; Mr. Dixon, none; Mr. Jansing, $18; Mr. MacDonald,  none; Mr. Millican,  $21
and Mr. Neff, $20.

2. Each Lord  Abbett-sponsored fund has a retirement plan providing that outside
directors may receive annual retirement benefits for life equal to 100% of their
final annual retainers following  retirement at or after age 72 with at least 10
years of  service.  Each plan also  provides  for a reduced  benefit  upon early
retirement  under  certain  circumstances,  a  pre-retirement  death benefit and
actuarially reduced  joint-and-survivor spousal benefits. Such retirement plans,
and the  deferred  compensation  plans  referred to in footnote  one,  have been
amended  recently to, among other things,  enable outside  directors to elect to
convert their  prospective  benefits under the retirement  plans to equity-based
benefits under the deferred  compensation  plans (renamed the equity-based plans
and  hereinafter  referred  to as  such).  All  outside  directors  made such an
election.   The  amounts   accrued  in  column  3  were   accrued  by  the  Lord
Abbett-sponsored  funds  during the  fiscal  year ended  October  31,  1996 with
respect to the equity-based  plans.  These accruals were based on the retirement
plans as in effect  before  the  recent  amendments  and on the fees  payable to
outside  directors of the Fund during the year ended October 31, 1996. Under the
recent  amendments,  the annual retainer was increased to $50,000 and the annual
equity-based  benefits  were  increased  from 80% to 100% of a director's  final
annual retainer.  The amounts stated in column 4 would be payable annually under
the retirement  plans as recently amended if the directors were to retire at age
72 and the  annual  retainers  payable  by the  funds  were the same as they are
today.

3. This column shows aggregate compensation, including directors fees and 
attendance fees for board and committee meetings, ofa nature referred to in
footnote one, accrued by the Lord Abbett-sponsored funds during the year
ended December 31,1995.

The Fund's By-Laws provide that the 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  or by
stockholders  holding at least one quarter of the stock of the Fund  outstanding
and entitled to vote at the meeting.  When any such annual  meeting is held, the
stockholders  will elect  directors and vote on the approval of the  independent
auditors of the Fund.

As of March 1, 1997 our officers and  directors as a group owned less than 1% of
our outstanding shares.

                                  3.
                Investment Advisory and Other Services

As described under "Our Management" in the Prospectus, Lord Abbett is the Fund's
investment  manager.  The ten general  partners of Lord Abbett,  all of whom are
officers  and/or  directors of the Fund, are:  Stephen I. Allen,  Zane E. Brown,
Daniel E. Carper,  Kenneth B. Cutler,  Robert S. Dow, Daria L. Foster, Robert G.
Morris,  Robert J. Noelke,  E. Wayne Nordberg and John J. Walsh.  The address of
each partner is The General  Motors  Building,  767 Fifth Avenue,  New York, New
York 10153-0203.

The services  performed by Lord Abbett are described  under "Our  Management" in
the  Prospectus.  Under the Management  Agreement,  we are obligated to pay Lord
Abbett a monthly fee,  based on average daily net assets for each month,  at the
annual rate of .75 of 1% of each Series'  average daily net assets.  In addition
we are  obligated  to pay all  expenses  not  expressly  assumed by Lord Abbett,
including, without limitation, outside directors' fees and expenses,

                                         12

<PAGE>



association  membership  dues,  legal and  auditing  fees,  taxes,  transfer and
dividend disbursing agent fees,  shareholder  servicing costs, expenses relating
to  shareholder  meetings,  expenses of  preparing,  printing and mailing  stock
certificates and shareholder  reports,  expenses of registering our shares under
federal and state securities laws,  expenses of preparing,  printing and mailing
prospectuses to existing shareholders,  insurance premiums,  brokerage and other
expenses connected with executing portfolio  transactions.  For the fiscal years
ended November 30, 1995 and 1994, although not obligated to, Lord Abbett assumed
the  above-mentioned  expenses of the Large-Cap Series, in the amount of $18,000
for each year.

Although not obligated to do so, Lord Abbett waived all of its  management  fees
with respect to the  Large-Cap  Series for the fiscal  years ended  November 30,
1994 and 1995 and a portion of its fee for the fiscal  year ended  1996.  Absent
such waiver the  management  fees for the fiscal years ended  November 30, 1994,
1995 and 1996 would have been $33,861, $50,255 and $78,668 respectively. For the
fiscal year ended November 30, 1996 Lord Abbett  received  $38,364 in management
fees with respect to the Large-Cap Series.


For the period  December 13, 1995  (commencement  of operations) to November 30,
1996,  Lord  Abbett  waived  $24,461  in  management  fees with  respect  to the
Small-Cap  Series.  For the  same  time  period,  Lord  Abbett  did not  receive
management fees with respect to the Small-Cap Series.

Deloitte & Touche LLP, Two World Financial Center,  New York, New York 10281 are
the  independent  accountants of the Fund and must be approved at least annually
by the Fund's  Board of  Directors  to continue in such  capacity.  They perform
audit  services for the Fund including the  examination of financial  statements
included in our annual report to shareholders.

The Bank of New York ("BNY"),  48 Wall Street,  New York, New York 10268, is the
Fund's custodian.  In accordance with the requirements of Rule 17f-5, the Fund's
directors  have approved  arrangements  permitting the Fund's foreign assets not
held by BNY or its  foreign  branches  to be held by certain  qualified  foreign
banks and depositories.

                                     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.  Such services include showing
us trading opportunities including blocks, a willingness and

                                     13

<PAGE>



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  November  30,  1994,  1995 and 1996 we paid total
commissions to independent  broker-dealers of $8,033, $7,832 and $28,649 for the
Large-Cap Series,  respectively.  For the period December 13, 1995 (commencement
of  operations)  to November 30, 1996, we paid total  commissions to independent
broker-dealers of $45,266 for the Small-Cap Series.

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,  Presidents' Day, Good Friday,  Memorial Day,  Independence Day,
Labor Day, Thanksgiving and Christmas.

The 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.

The net asset value per share for the Class B and C shares will be determined in
the same  manner  as for the  Class A  shares  (net  assets  divided  by  shares
outstanding).

The maximum offering price of Class A shares of the Large-Cap Series on November
30, 1996 was computed as follows:

                                                                   CLASS A
Net asset value per share (net assets divided
by shares outstanding)..............................................$17.86

Maximum offering price per share (net asset
value divided by .9425).............................................$18.95


The maximum offering price of Class A shares of the Small-Cap Series on November
30, 1996 was computed as follows:

                                                                   CLASS A
Net asset value per share (net assets divided
by shares outstanding). . . . . . . . . .  . . . . . .  . . . . .  $12.01

Maximum offering price per share (net asset
value divided by .9425)........................................... $12.74

Our Class B and C shares will be offered at net asset value.

The 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 the 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.

For  the  last  three  fiscal  years  Lord  Abbett,   as  the  Fund's  principal
underwriter,  received net commissions after allowance of a portion of the sales
charge to independent dealers with respect to Class A shares as follows:

CONVERSION  OF CLASS B SHARES.  The  conversion  of Class B shares on the eighth
anniversary  of their purchase is subject to the  continuing  availability  of a
private  letter  ruling  from the  Internal  Revenue  Service,  or an opinion of
counsel or tax adviser, to the effect that the conversion of Class B shares does
not  constitute a taxable event for the holder under Federal  income tax law. If
such  a  revenue  ruling  or  opinion  is no  longer  available,  the  automatic
conversion  feature may be suspended,  in which event no further  conversions of
Class B shares would occur while such  suspension  remained in effect.  Although
Class B shares  could  then be  exchanged  for  Class A shares  on the  basis of
relative net asset value of the two classes,  without the  imposition of a sales
charge or fee, such exchange could constitute a taxable event for the holder.

CLASS A, B AND C RULE 12B-1 PLANS. As described in the Prospectus,  the Fund has
adopted  on  behalf  of each  class  of each  Series,  a  Distribution  Plan and
Agreement  pursuant to Rule 12b-1 of the Act:  the "A Plans",  the "B Plans" and
the "C  Plans",  respectively.  In  adopting  each  Plan  and in  approving  its
continuance,  the Board of Directors  has  concluded  that there is a reasonable
likelihood  that each Plan will  benefit  its  respective  Class and such Class'
shareholders.  The expected benefits include greater sales and lower redemptions
of Class  shares,  which should  allow each Class to maintain a consistent  cash
flow, and a higher quality of service to shareholders by authorized institutions
than would  otherwise  be the case.  The C Plan will go into  effect on April 1,
1997.  Lord Abbett used all amounts  received  under each A Plan for payments to
dealers for (i) providing continuous services to the Class A shareholders,  such
as  answering   shareholder   inquiries,   maintaining  records,  and  assisting
shareholders  in  making  redemptions,   transfers,   additional  purchases  and
exchanges  and (ii)  their  assistance  in  distributing  Class A shares of each
Series.

The fees  payable  under  the A Plan,  B Plan and C Plan  are  described  in the
Prospectus.  For the fiscal  year ended  November  30, 1996 fees paid to dealers
under  the A Plans for the  Large-Cap  Series  were  $3,700  and for the  period
December 13, 1995  (commencement  of  operations)  to November  30,  1996,  with
respect to the Small-Cap Series were $343.

For the fiscal year ended  November  30,  1996 fees paid to dealers  under the B
Plans for the Large-Cap Series were $11,900 and for the period December 13, 1995
(commencement  of  operations)  to November 30, 1996,  for the Small- Cap Series
were $131.

Each Plan  requires  the  directors  to review,  on a quarterly  basis,  written
reports of all amounts expended  pursuant to the Plan and the purposes for which
such  expenditures  were made.  Each Plan shall  continue  in effect only if its
continuance is specifically approved at least annually by vote of the directors,
including a majority of the directors who are not interested persons of the Fund
and who have no direct or indirect  financial  interest in the  operation of the
Plan or in any  agreements  related to the Plan ("outside  directors"),  cast in
person at a meeting called for the purpose of voting on the Plan. No Plan may be
amended to  increase  materially  above the limits set forth  therein the amount
spent for distribution expenses thereunder without approval by a majority of the
outstanding  voting  securities  of the  applicable  Class and the approval of a
majority of the directors,  including a majority of the outside directors.  Each
Plan may be terminated at

                                           16

<PAGE>



any time by vote of a majority of the outside directors or by vote of a majority
of its Class's outstanding voting securities.

CONTINGENT  DEFERRED SALES CHARGES. A Contingent  Deferred Sales Charge ("CDSC")
(i) applies  regardless of class, (ii) will not apply to shares purchased by the
reinvestment of dividends or capital gains distributions; (iii) will be assessed
on the lesser of the net asset value of the shares at the time of  redemption or
the original  purchase  price and (iv) will not be imposed on the amount of your
account  value  represented  by the increase in net asset value over the initial
purchase price  (including  increases due to the  reinvestment  of dividends and
capital gains distributions) and upon early redemption of shares.

CLASS A SHARES.  As  stated  in the  Prospectus,  a CDSC of 1% is  imposed  with
respect  to  those   Class  A  shares  (or  Class  A  shares  of  another   Lord
Abbett-sponsored  fund or series  acquired  through  exchange of such shares) on
which the Fund has paid the one-time  distribution  fee of 1% if such shares are
redeemed out of the Lord Abbett-sponsored  family of funds within a period of 24
months from the end of the month in which the original sale occurred.

CLASS B  SHARES.  As  stated in the  Prospectus,  if Class B shares  (or Class B
shares of another Lord Abbett-sponsored fund or series acquired through exchange
of such shares) are redeemed  out of the Lord  Abbett-sponsored  family of funds
for cash before the sixth anniversary of their purchase, a CDSC will be deducted
from  the  redemption  proceeds.  The  Class  B CDSC  is  paid  to  Lord  Abbett
Distributor  to  reimburse  its  expenses,  in whole or in part,  for  providing
distribution-related  service to the Fund in connection with the sale of Class B
shares.

To determine  whether the CDSC applies to a redemption,  the Fund redeems shares
in the following  order:  (1) shares  acquired by  reinvestment of dividends and
capital gains  distributions,  (2) shares held on or after the sixth anniversary
of  their  purchase,   and  (3)  shares  held  the  longest  before  such  sixth
anniversary.

The amount of the contingent  deferred sales charge will depend on the number of
years since you invested and the dollar amount being redeemed,  according to the
following schedule:

Anniversary of the Day on                       Contingent Deferred Sales Charge
Which the Purchase                                      on Redemptions
Order was Accepted                            (As % of Amount Subject to Charge)
Before the 1st................................................5.0%
On the 1st, before the 2nd..... ..............................4.0%
On the 2nd, before the 3rd....................................3.0%
On the 3rd, before the 4th....................................3.0%
On the 4th, before the 5th....................................2.0%
On the 5th, before the 6th ...................................1.0%
On or after the 6th anniversary...............................None

In the table, an  "anniversary" is the 365th day subsequent to the acceptance of
a purchase  order or a prior  anniversary.  All purchases are considered to have
been made on the business day on which the purchase order was accepted.

CLASS C SHARES. As stated in the Prospectus,  if Class C shares are redeemed for
cash before the first anniversary of their purchase,  the redeeming  shareholder
will be  required to pay to the Fund on behalf of Class C shares a CDSC of 1% of
the lower of cost or the then net  asset  value of Class C shares  redeemed.  If
such shares are exchanged  into the same class of another Lord  Abbett-sponsored
fund and  subsequently  redeemed before the first  anniversary of their original
purchase,  the  charge  will be  collected  by the  other  fund on behalf of the
Series' Class C shares.

GENERAL.  Each percentage (1% in the case of Class A and C shares and 5% through
1% in the case of Class B shares) used to calculate  CDSCs  described  above for
the Class A, Class B and Class C shares is sometimes  hereinafter referred to as
the "Applicable Percentage".


                                         17

With respect to Class A and Class B shares, no CDSC is payable on redemptions by
participants or beneficiaries from employer-sponsored retirement plans under the
Internal  Revenue  Code  for  benefit  payments  due  to  plan  loans,  hardship
withdrawals,  death,  retirement or  separation  from service and for returns of
excess  contributions  to  retirement  plan  sponsors.  With  respect to Class B
shares,  no CDSC is payable for  redemptions  (i) in connection  with Systematic
Withdrawal  Plan and Div-Move  services as described below under those headings,
(ii) in connection with mandatory  distribution  under 403(b) plans and IRAs and
(iii) in connection  with death of the  shareholder.  In the case of Class A and
Class C shares,  the CDSC is received  by the Fund and is intended to  reimburse
all or a portion  of the  amount  paid by the Fund if the  shares  are  redeemed
before the Fund has had an  opportunity to realize the  anticipated  benefits of
having a  long-term  shareholder  account  in the  Fund.  In the case of Class B
shares,  the CDSC is  received  by Lord  Abbett  Distributor  and is intended to
reimburse  its  expenses of providing  distribution-related  service to the Fund
(including  recoupment of the commission  payments made) in connection  with the
sale of Class B shares before Lord Abbett  Distributor has had an opportunity to
realize its  anticipated  reimbursement  by having such a long-term  shareholder
account subject to the B Plan distribution fee.

The other funds and series which participate in the Telephone Exchange Privilege
(except (a) Lord Abbett U.S.  Government  Securities  Money  Market  Fund,  Inc.
("GSMMF"),  (b)  certain  series of Lord  Abbett  Tax-Free  Income Fund and Lord
Abbett  Tax-Free  Income Trust for which a Rule 12b-1 Plan is not yet in effect,
and (c) any authorized  institution's  affiliated  money market fund  satisfying
Lord  Abbett  Distributor  as to certain  omnibus  account  and other  criteria,
hereinafter  referred  to  as  an  "authorized  money  market  fund"  or  "AMMF"
(collectively,  the "Non-12b-1 Funds")) have instituted a CDSC for each class on
the same terms and conditions.  No CDSC will be charged on an exchange of shares
of the same class between Lord Abbett funds or between such funds and AMMF. Upon
redemption of shares out of the Lord Abbett family of funds or out of AMMF,  the
CDSC  will be  charged  on  behalf  of and  paid:  (i) to the fund in which  the
original purchase  (subject to a CDSC) occurred,  in the case of the Class A and
Class C shares and (ii) to Lord Abbett  Distributor if the original purchase was
subject to a CDSC, in the case of the Class B shares.  Thus, if shares of a Lord
Abbett fund are  exchanged for shares of the same class of another such fund and
the shares of the same class  tendered  ("Exchanged  Shares")  are  subject to a
CDSC,  the CDSC will carry over to the shares of the same class being  acquired,
including GSMMF and AMMF ("Acquired  Shares").  Any CDSC that is carried over to
Acquired  Shares is calculated as if the holder of the Acquired  Shares had held
those shares from the date on which he or she became the holder of the Exchanged
Shares.  Although the Non-12b-1  Funds will not pay a distribution  fee on their
own shares, and will, therefore,  not impose their own CDSC, the Non-12b-1 Funds
will collect the CDSC (a) on behalf of other Lord Abbett  funds,  in the case of
the Class A and Class C shares and (b) on behalf of Lord Abbett Distributor,  in
the case of the Class B shares. Acquired Shares held in GSMMF and AMMF which are
subject to a CDSC will be  credited  with the time such shares are held in GSMMF
but will not be credited with the time such shares are held in AMMF.  Therefore,
if your Acquired Shares held in AMMF qualified for no CDSC or a lower Applicable
Percentage at the time of exchange into AMMF,  that  Applicable  Percentage will
apply to  redemptions  for cash from AMMF,  regardless of the time you have held
Acquired Shares in AMMF.

In no event will the amount of the CDSC exceed the Applicable  Percentage of the
lesser of (i) the net asset value of the shares  redeemed  or (ii) the  original
cost of such  shares (or of the  Exchanged  Shares for which  such  shares  were
acquired). No CDSC will be imposed when the investor redeems (i) amounts derived
from  increases in the value of the account above the total cost of shares being
redeemed due to increases in net asset value,  (ii) shares with respect to which
no Lord Abbett  fund paid a 12b-1 fee and,  in the case of Class B shares,  Lord
Abbett  Distributor  paid no sales  charge  or  service  fee  (including  shares
acquired   through   reinvestment   of  dividend   income  and   capital   gains
distributions) or (iii) shares which,  together with Exchanged Shares, have been
held  continuously for 24 months from the end of the month in which the original
sale  occurred  (in the case of Class A  shares);  for six years or more (in the
case  of  Class B  shares)  and for one  year or more  (in the  case of  Class C
shares). In determining whether a CDSC is payable, (a) shares not subject to the
CDSC will be redeemed  before  shares  subject to the CDSC and (b) of the shares
subject to a CDSC, those held the longest will be the first to be redeemed.

EXCHANGES.  The Prospectus briefly describes the Telephone  Exchange  Privilege.
You may  exchange  some or all of your shares of any class for those in the same
class of: (i) Lord Abbett-sponsored funds currently offered to the public with a
sales charge  (front-end,  back-end or level ), (ii) GSMMF or (iii) AMMF, to the
extent offers and sales may be made

                                       18

<PAGE>



in your  state.  You  should  read  the  prospectus  of the  other  fund  before
exchanging.  In  establishing  a new account by  exchange,  shares of the Series
being  exchanged  must  have a value  equal  to at  least  the  minimum  initial
investment required for the other fund into which the exchange is made.

Shareholders in other Lord  Abbett-sponsored  funds and AMMF have the same right
to exchange  their shares for the  corresponding  class of each Series'  shares.
Exchanges  are based on relative  net asset values on the day  instructions  are
received by the Fund in Kansas City if the  instructions  are received  prior to
the close of the NYSE in proper form. No sales charges are imposed except in the
case of  exchanges  out of  GSMMF or AMMF  (unless  a sales  charge  (front-end,
back-end or level) was paid on the initial investment in a Lord Abbett-sponsored
fund).  Exercise of the exchange privilege will be treated as a sale for federal
income tax purposes, and, depending on the circumstances,  a gain or loss may be
recognized. In the case of an exchange of shares that have been held for 90 days
or less where no sales charge is payable on the  exchange,  the  original  sales
charge incurred with respect to the exchanged  shares will be taken into account
in  determining  gain or loss on the  exchange  only to the extent  such  charge
exceeds the sales charge that would have been payable on the acquired shares had
they been acquired for cash rather than by exchange. The portion of the original
sales charge not so taken into  account will  increase the basis of the acquired
shares.

Shareholders have the exchange  privilege unless they refuse it in writing.  You
should  not view the  exchange  privilege  as a means for  taking  advantage  of
short-term swings in the market,  and we reserve the right to terminate or limit
the privilege of any shareholder who makes frequent exchanges.  We can revoke or
modify the privilege for all shareholders upon 60 days' prior notice.  "Eligible
Funds" are AMMF and other Lord Abbett-sponsored funds which are eligible for the
exchange  privilege,  except Lord Abbett Series Fund  ("LASF")  which offers its
shares only in connection with certain variable annuity  contracts,  Lord Abbett
Equity  Fund  ("LAEF")  which is not issuing  shares,  and series of Lord Abbett
Research Fund not offered to the general public ("LARF").

STATEMENT OF INTENTION.  Under the terms of the Statement of Intention to invest
$50,000 or more over a 13-month period as described in the Prospectus, shares of
a Lord  Abbett-sponsored  fund (other than shares of LAEF, LASF, LARF, GSMMF and
AMMF,  unless holdings in GSMMF and AMMF are  attributable  to shares  exchanged
from a Lord  Abbett-sponsored  fund offered with a front-end,  back-end or level
sales charge) currently owned by you are credited as purchases (at their current
offering prices on the date the Statement is signed) toward achieving the stated
investment and reduced  initial sales charge for Class A shares.  Class A shares
valued  at 5% of the  amount  of  intended  purchases  are  escrowed  and may be
redeemed to cover the  additional  sales charge  payable if the Statement is not
completed.  The Statement of Intention is neither a binding obligation on you to
buy, nor on the Fund to sell, the full amount indicated.

RIGHTS OF ACCUMULATION.  As stated in the Prospectus,  purchasers (as defined in
the Prospectus) may accumulate their investment in Lord  Abbett-sponsored  funds
(other than LAEF, LARF,  LASF,  GSMMF, and AMMF unless holdings in GSMMF or AMMF
are attributable to shares exchanged from a Lord  Abbett-sponsored  fund offered
with a front-end,  back-end or level sales charge) so that a current investment,
plus the  purchaser's  holdings  valued at the current  maximum  offering price,
reach a level eligible for a discounted sales charge for Class A shares.

NET ASSET VALUE PURCHASES OF CLASS A SHARES.  As stated in the  Prospectus,  our
Class A shares may be purchased at net asset value by our  directors,  employees
of Lord Abbett,  employees of our  shareholder  servicing agent and employees of
any securities  dealer having a sales agreement with Lord Abbett who consents to
such   purchases  or  by  the  director  or  custodian   under  any  pension  or
profit-sharing plan or Payroll Deduction IRA established for the benefit of such
persons  or for the  benefit  of  employees  of any  national  securities  trade
organization  to which Lord Abbett  belongs or any company with an account(s) in
excess of $10  million  managed  by Lord  Abbett  on a  private-advisory-account
basis.  For purposes of this  paragraph,  the terms  "directors" and "employees"
include a trustee's or employee's  spouse  (including the surviving  spouse of a
deceased director or employee). The terms "our directors" and "employees of Lord
Abbett" also include other family members and retired directors and employees.

Our Class A shares also may be purchased at net asset value (a) at $1 million or
more,  (b) with  dividends and  distributions  from Class A shares of other Lord
Abbett-sponsored  funds,  except  for LARF,  LAEF and  LASF,  (c) under the loan
feature of the Lord  Abbett-sponsored  prototype 403(b) plan for share purchases
representing the repayment

                                         19

<PAGE>



of  principal  and  interest,  (d)  by  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 shares in particular  investment products made available for a fee to
clients of such  brokers,  dealers,  registered  investment  advisers  and other
financial  institutions,  ("mutual  fund wrap fee  program"),  (e) by employees,
partners  and owners of  unaffiliated  consultants  and advisors to Lord Abbett,
Lord  Abbett  Distributor  or Lord  Abbett-sponsored  funds who  consent to such
purchase if such persons provide service to Lord Abbett, Lord Abbett Distributor
or such  funds on a  continuing  basis and are  familiar  with such  funds,  (f)
through Retirement Plans with at least 100 eligible  employees,  (g) our Class A
shares  also  may be  purchased  at net  asset  value,  subject  to  appropriate
documentation,  through a securities dealer where the amount invested represents
redemption  proceeds from shares  ("Redeemed  Shares") of a registered  open-end
management  investment  company not distributed or managed by Lord Abbett (other
than a money market fund),  if such redemption has occurred no more than 60 days
prior to the purchase of our shares,  the Redeemed Shares were held for at least
six months prior to redemption and the proceeds of redemption were maintained in
cash or a money market fund prior to purchase.  Purchasers  should  consider the
impact, if any, of contingent  deferred sales charges in determining  whether to
redeem shares for subsequent  investment in our Class A shares.  Lord Abbett may
suspend,  change or terminate this purchase  option  referred to in (g) above at
any time.  We plan on June 1, 1997 to  terminate  this net asset value  transfer
privilege.  Shares are  offered at net asset  value to these  investors  for the
purpose of promoting  goodwill  with  employees and others with whom Lord Abbett
Distributor and/or the Fund has business relationships.


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 the Prospectus for expedited redemption procedures.

The right to redeem and receive payment, as described in the 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  may  authorize  redemption  of all of the shares in any
account  in which  there are  fewer  than 25  shares.  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.

DIV-MOVE. Under the Div-Move service described in the Prospectus, you can invest
the dividends paid on your account of any class into an existing  account of the
same class in any other  Eligible Fund. The account must be either your account,
a joint account for you and your spouse, a single account for your spouse,  or a
custodial  account for your minor child under the age of 21. You should read the
prospectus of the other fund before investing.

INVEST-A-MATIC.  The  Invest-A-Matic  method of investing in the Fund and/or any
other  Eligible Fund is described in the  Prospectus.  To avail yourself of this
method you must complete the application form,  selecting the time and amount of
your bank checking account  withdrawals and the funds for investment,  include a
voided, unsigned check and complete the bank authorization.

SYSTEMATIC  WITHDRAWAL  PLANS.  The Systematic  Withdrawal  Plan ("SWP") also is
described  in the  Prospectus.  You may  establish  a SWP if you own or purchase
uncertificated shares having a current offering price value of at least $10,000.
Lord Abbett prototype  retirement plans have no such minimum.  With respect to a
SWP for Class B shares,  the CDSC will be waived for  redemptions of 12% or less
per year and for  redemptions  over 12% per  year,  the CDSC  will  apply to the
entire  redemption.  Therefore,  please  contact  the  Fund  for  assistance  in
minimizing the CDSC in this situation.  With respect to Class C shares, the CDSC
will be waived on and after the first  anniversary  of their  purchase.  The SWP
involves  the  planned  redemption  of shares on a periodic  basis by  receiving
either fixed or variable amounts

                                      20

<PAGE>



at periodic  intervals.  Since the value of shares  redeemed may be more or less
than their cost,  gain or loss may be recognized for income tax purposes on each
periodic  payment.  Normally,  you may not make regular  investments at the same
time you are receiving systematic  withdrawal payments because it is not in your
interest to pay a sales  charge on new  investments  when in effect a portion of
that new investment is soon withdrawn.  The minimum investment  accepted while a
withdrawal  plan is in effect is $1,000.  The SWP may be terminated by you or by
us at any time by written notice.

RETIREMENT  PLANS.  The Prospectus  indicates the types of retirement  plans for
which Lord Abbett provides forms and  explanations.  Lord Abbett makes available
the retirement plan forms,  including 401(k) plans and custodial  agreements for
IRAs  (Individual  Retirement  Accounts,  including  Simple IRAs and  Simplified
Employee Pensions), 403(b) plans and qualified pension and profit-sharing plans.
The forms name  Investors  Fiduciary  Trust  Company as  custodian  and  contain
specific   information   about  the  plans.   Explanations  of  the  eligibility
requirements,  annual  custodial fees and allowable tax advantages and penalties
are set forth in the  relevant  plan  documents.  Adoption of any of these plans
should be on the advice of your legal counsel or qualified tax adviser.


                                      6.
                              Past Performance

Each Series computes the average annual compounded rate of total return for each
class 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 the maximum 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 the Prospectus.  The ending
redeemable  value is determined by assuming a complete  redemption at the end of
the period(s) covered by the average annual total return computation.

In  calculating  total  returns for Class A shares,  the current  maximum  sales
charge of 5.75% (as a  percentage  of the offering  price) is deducted  from the
initial  investment (unless the return is shown at net asset value). For Class B
shares,  the payment of the applicable CDSC (5.0% prior to the first anniversary
of purchase, 4.0% prior to the second anniversary of purchase, 3.0% prior to the
third and fourth anniversaries of purchase,  2.0% prior to the fifth anniversary
of purchase,  1.0% prior to the sixth anniversary of purchase and no CDSC on and
after the sixth  anniversary  of purchase) is applied to the Series'  investment
result for that class for the time  period  shown  (unless  the total  return is
shown at net asset value).  For Class C shares,  the 1.0% CDSC is applied to the
Series'  investment result for that class for the time period shown prior to the
first  anniversary  of purchase  (unless the total  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.  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.

Using the method to compute  average annual  compounded  total return  described
above,  for the Class A shares of the Large-Cap Series for the one year, and the
life-of-Series  periods (from commencement of operations on June 3, 1992 through
November 30, 1996) assuming a $1,000  investment at the beginning of the period,
the  average  annual  rates of total  return  were  19.00%  and  18.40%  and the
redeemable values amounted to $1,190 and $2,136,  respectively.  With respect to
Class A shares of the Small-Cap Series for the life-of-Series,  (commencement of
operations  December  13, 1995  through  November  30,  1996)  assuming a $1,000
investment  at the  beginning  of the period,  the average  annual rate of total
return was 20.80% (not annualized) and the redeemable value amounted to $1,208.

Our  yield  quotation  for each  class 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 maximum  offering  price 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

                                         21

<PAGE>



the period for a 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 maximum offering
price 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.
Yield for the Class A shares reflects the deduction of the maximum initial sales
charge,  but may also be shown  based on the Class A net asset  value per share.
Yields for Class B and C shares do not reflect the deduction of the CDSC.

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 Series 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 Series'  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  Series  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
Series  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 Series 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 Series.  Such  transactions  may increase the amount of short-term  capital
gain realized by each Series, which is taxed as ordinary income when distributed
to shareholders.  Limitations  imposed by the Internal Revenue Code on regulated
investment companies may restrict each Series' ability to engage in transactions
in options.

Certain  futures  contracts and certain  listed options held by a Series 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 Series'
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.  The Series 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 Series.

As described in the Prospectus under "How We Invest - Risk Factors," each Series
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 Series
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 Series.

Gains and losses  realized  by each  Series 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.


                                         22

<PAGE>


If either Series 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 Series to its shareholders.  Additional charges in the nature of
interest may be imposed on either the Series or its  shareholders  in respect to
deferred taxes arising from such distributions or gains.

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


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

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
Series,  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 Series shares.

                       Information About the Fund

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.

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  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-
                727 of the New York Business Corporation Law.



<PAGE>



                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

                      EQUITY-BASED PLANS FOR NON-INTERESTED
               PERSON DIRECTORS AND TRUSTEES OF LORD ABBETT FUNDS
                (As Amended and Restated as of September 1, 1996)


1.       PURPOSE.

                  The purpose of these  Equity-Based  Plans for Non-  Interested
Person  Directors  and  Trustees  (collectively,  the  "Equity-Based  Plans" and
separately,  an "Equity-Based  Plan"),  which were initially called the Deferred
Compensation  Plan for  Non-Interested  Person  Directors  and  Trustees of Lord
Abbett Funds, is to provide  eligible  directors and trustees of each investment
company referred to on Schedule I that has adopted an Equity-Based  Plan and any
other investment company sponsored and managed by Lord, Abbett & Co. that adopts
an Equity-Based Plan (collectively, the "Companies" and separately, a "Company")
with the  opportunity  to defer the  receipt of  compensation  earned by them as
directors  and  trustees  in  lieu of  receiving  payment  of such  compensation
currently and to give them to the extent of such deferred compensation and other
compensation  a  pecuniary  interest  in  the  investment   performance  of  the
Companies. The Plans constitute a separate Plan of each Company.






<PAGE>



2.       ELIGIBILITY.
                  Any member of the Board of Trustees  (if a Company is a trust)
and any member of the Board of Directors  (if a Company is a  corporation)  of a
Company (the "Board") who is not an "interested  person" of such Company as such
term is defined in the  Investment  Company Act of 1940 (an  "Independent  Board
Member")  shall be  eligible  to  participate  in the Plan of such  Company.  3.
AMOUNTS OF DEFERRALS.
                  (a) ACCRUED PENSION PLAN DEFERRALS.  The "Retirement  Plan for
Non-Interested Person Directors and Trustees of Lord Abbett Funds" (the "Pension
Plan") has been amended, effective October 16, 1996, to provide that Independent
Board Members may elect to receive equity-based  benefits under the Equity-Based
Plans in lieu of retirement  benefits  under the Pension Plan.  Any  Independent
Board Member who makes such an election by the close of business on November 29,
1996 shall not be entitled to retirement  benefits  under the Pension Plan,  but
shall have his Account (as defined in section 4) for each Company increased,  as
of November  29,  1996,  through  credit of an amount equal to the value of such
Independent Board Member's retirement benefits under such Company's Pension Plan
(prior to giving effect to






<PAGE>



such amendment) as accrued to such date to reflect the terms
of the Pension Plan.
                  (b) MANDATORY  DEFERRALS.  Each  Independent  Board Member who
makes the  election  referred to in the  foregoing  section 3(a) by the close of
business on November 29, 1996, and each Independent  Board Member who becomes an
Independent Board Member after such date, shall defer receipt of such amount, if
any, of the compensation  earned by such Independent Board Member for serving as
a member of the Board or as a member of any committee (or  subcommittee  of such
committee) of the Board of which such Independent Board Member from time to time
may be a member as may be  specified  with  respect  to such  Independent  Board
Member from time to time by resolution of the Independent Board Members.
                  (c) OPTIONAL DEFERRALS.  In addition to the above deferrals an
Independent  Board  Member  may  elect to defer  receipt  of all or a  specified
portion of any other compensation (including fees for attending meetings) earned
by such  Independent  Board  Member  by  notice to the  Companies.  Expenses  of
attending  meetings of the Board,  committees of the Board or  subcommittees  of
such committees may not be deferred.






<PAGE>



4.       EQUITY-BASED ACCOUNTS.
                  A deferred  compensation  equity-based account (the "Account")
shall be  established  by each  Company  in the name of each  Independent  Board
Member.  Any  amounts  credited to an Account  pursuant to section  3(a) will be
credited  as of the close of business on November  29,  1996.  Any  compensation
earned by an Independent  Board Member during any year and deferred  pursuant to
section 3(b) will be credited to such  Independent  Board Member's  Account on a
quarterly basis on the last days of March, June,  September and December of such
year.  Any  compensation  deferred by an  Independent  Board Member  pursuant to
section 3(c) will be credited to such Independent  Board Member's Account on the
date such  compensation  otherwise  would have been payable to such  Independent
Board Member. 5. ACCOUNT INVESTMENT.
                  (a) TREATMENT OF CREDIT AMOUNTS.  Any amounts  credited at any
time to an Independent Board Member's Account  established by a Company shall be
deemed  invested  in a number of shares,  which  shall be class A shares if such
Company has multiple classes of shares,  of such Company's Common Stock equal to
the  quotient  of (i) the amount  credited  to the  Independent  Board  Member's
Account divided







<PAGE>



by (ii) the Net Asset Value per share as of the date such amount is so credited.
The Net Asset Value per share shall be  determined as set forth in the Company's
Articles of Incorporation.  If such Company has more than one series, the amount
credited to the Independent Board Member's Account shall be allocated between or
among the series on the same basis as the compensation being deferred is charged
to the series (or, in the case of an amount  credited  pursuant to section 3(a),
on the same basis as the amount thereof was charged to the series).
                  (b)  MERGERS,  ETC. In the event that the Company  shall pay a
stock  dividend  on,  or split  up,  combine,  reclassify  or  substitute  other
securities by merger, consolidation or otherwise for its outstanding shares, the
number of shares  credited to the  Independent  Board Member's  Account shall be
adjusted  to  preserve  rights  substantially  proportionate  to the rights held
immediately prior to such event.
                  (c)  DISTRIBUTIONS.  On each  payable  date of a  dividend  or
capital gains distribution  declared by the Board of a Company, the Account will
be  credited  with the number of full and  fractional  shares of the  Company or
series that the shares of such Company or series deemed to be held in







<PAGE>



the Account would have purchased if such dividend or
distribution had been reinvested at the Net Asset Value on
the investment date established by the Board with respect to
such dividend or distribution.

6.       MANNER OF ELECTING OPTIONAL DEFERRALS; PAYMENT
         ELECTIONS.

                  election is made; and






<PAGE>



         (iv)     the first business day of a month not earlier than
                  the earliest of the dates referred to in (i), (ii)
                  and (iii) above.
                  (d) FAILURE TO DESIGNATE.  If an Independent  Board Member who
participates  in a Plan  fails to  designate  in his Notice a time or date as of
which  payment  of his  Account  (or any part of his  Account)  shall  commence,
payment of such amount  shall  commence as of the date set forth in (b)(i) above
(unless the Independent  Board Member files an amended Notice in compliance with
section 8(b) selecting a different  distribution  date). If an Independent Board
Member fails to designate in his Notice the manner of  distribution  to apply to
his Account (or any part of his Account), such Account shall be distributed in a
lump sum  (unless  the  Independent  Board  Member  files an  amended  Notice in
compliance with section 8(b) selecting a different method of distribution).
                  (e)  DISSOLUTION,  ETC.  Deferrals  under  this Plan which are
deemed  invested  in shares  of a Company  (or  series  of a  Company)  shall be
distributed upon the  dissolution,  liquidation or winding up of the Company (or
other  termination  of the series),  whether  voluntary or  involuntary;  or the
voluntary sale, conveyance or transfer







<PAGE>



of all or  substantially  all of a Company's (or a series')  assets  (unless the
obligations  of the  Company  or the series  shall have been  assumed by another
investment company or another series of an investment company); or the merger of
a Company into another trust or  corporation  or its  consolidation  with one or
more other trusts or  corporations  (unless the  obligations  of the Company are
assumed by such surviving entity and such surviving entity is another investment
company).
                  (f)  HARDSHIP.  Upon application by an Independent
Board Member and a determination by the Compensation and
Nominating Committees of the Boards that the Independent
Board Member has suffered a severe and unanticipated
financial hardship, the Administrator shall distribute to
the Independent Board Member, in a single lump sum, an
amount equal to the lesser of the amount needed by the
Independent Board Member to meet the hardship (pro-rata
among the Accounts), or the balance of the Independent Board
Member's Accounts.

7.       EFFECTIVE DATE AND DURATION OF DEFERRAL ELECTIONS.
                  (a)  ELECTION IRREVOCABLE.  Except as provided in
sections 7(b) and 8(a), any election by an Independent Board
Member or nominee for election as an Independent Board






<PAGE>



Member to defer compensation  pursuant to section 3(c) shall be irrevocable from
and after the date on which such  person's  Notice is filed with the  Companies.
Elections to defer  compensation  pursuant to section 3(c) shall be effective to
defer an Independent Board Member's compensation as follows:
         (i)      As to any Independent Board Member in office on
                  the effective date of the Plans who files a Notice
                  no later than 60 days after such effective date,
                  the Notice shall be effective to defer any
                  compensation which may be deferred pursuant to
                  section 3(c) and is earned by such Independent
                  Board Member after the date of the filing of the
                  Notice;
    (ii)          As to any nominee for the office of trustee or
                  director who has not previously served as an
                  Independent Board Member and who files a Notice
                  prior to his election as an Independent Board
                  Member, such election to defer compensation
                  pursuant to section 3(c) shall be effective to
                  defer any compensation which may be deferred
                  pursuant to section 3(c) and is earned by such


<PAGE>



                  nominee after his election as an Independent Board
                  Member; and
   (iii)          As to any other Independent Board Member, the
                  election to defer compensation pursuant to sec
                  tion 3(c) shall be effective to defer any
                  compensation which may be deferred pursuant to
                  section 3(c) and is earned from and after January
                  1 of the calendar year next succeeding the year in
                  which the Notice is filed.
                  (b)  CONTINUANCE OF NOTICES.  Any election to
                       ----------------------
defer compensation  pursuant to section 3(c) made by an Independent Board Member
shall  continue in effect unless and until the Company is notified in writing by
such  Independent  Board Member  prior to the end of any  calendar  year that he
wishes to terminate such election or modify the amount of compensation  deferred
pursuant  to such  election.  Any  such  revocation  or  modification  shall  be
effective only with re spect to  compensation  earned after the calendar year in
which such amended Notice is filed with the Company. Upon receipt by the Company
from an  Independent  Board  Member of such an amended  Notice,  the  applicable
portion of compensation  earned by such Independent  Board Member from and after
January 1 of the calendar year succeeding the day




<PAGE>



on which such Notice was received shall be paid currently and no longer deferred
as provided in the Plan. However, any amounts in such Independent Board Member's
Account on such  January 1 and any amount  which the  Independent  Board  Member
thereafter defers shall continue to be payable in accordance with the Notice (or
Notices) pursuant to which it was deferred except as provided in section 8(a).
                  (c)  SUBSEQUENT NOTICE.  An Independent Board
Member who has filed a Notice to terminate deferment of
compensation may thereafter again file a Notice to
participate pursuant to section 6 hereof effective for the
calendar year subsequent to the calendar year in which he
files the new Notice.
8.       CHANGES IN FORM AND TIMING OF PAYMENT OF DEFERRED
         AMOUNTS.
                  An Independent Board Member may elect to change the timing and
manner of any distribution  election with respect to any or all amounts deferred
and  credited  with respect to the  Independent  Board Member under the Plans by
filing an amended Notice with the Companies
                  (a)  prior to the calendar year in which the
         Independent Board Member ceases to be an Independent
         Board Member of the Companies, and







<PAGE>



                  (b)  by a date such that at least one full
                       calendar year elapses between
                  (i)      the date as of which such amended Notice is
                           filed and
                 (ii)      each of
                           (A)  the date as of which a distribution
                                would otherwise have commenced and
                           (B) the date as of which such distribution
                                will commence under such amended Notice.
No such amended Notice shall, however, provide for payment of an amount credited
under  section 3(a) or 3(b) earlier than  permitted in  accordance  with section
6(c),  except as provided in section  9(b).  9.  PAYMENT OF AMOUNTS  CREDITED TO
ACCOUNTS.
                  (a) MANNER OF PAYMENT. An Account established by a Company for
an Independent  Board Member will be paid in a lump sum or in  installments,  or
both,  as  specified in his Notice or amended  Notice,  and at the time or times
specified in the Notice or amended  Notice.  If  installments  are elected by an
Independent Board Member, such installments shall be paid in cash and the amount
of the first cash  payment  shall be a fraction of the then value of the portion
of such Account to be paid in installments, the numerator of







<PAGE>



which is one, and the denominator of which is the total number of  installments.
The amount of each subsequent cash payment shall be a fraction of the then value
of such portion of such Account remaining after the prior payment, the numerator
of which is one and the denominator of which is the total number of installments
elected  minus the  number of  installments  previously  paid.  If a lump sum is
elected,  payment shall be made in the full and fractional shares of the Company
(and of any series of such  Company)  in which the  portion of such  Independent
Board Member's Account to be paid in a lump sum is deemed invested.
                  (b)  PAYMENT TO  BENEFICIARY.  In the event of an  Independent
Board Member's death before he has received payment of all amounts in an Account
established by a Company for such  Independent  Board Member,  the value of such
Account shall be paid to the beneficiary  designated in such  Independent  Board
Member's Notice or, if no such  beneficiary is designated,  to such  Independent
Board Member's  estate,  in accordance  with the provisions of the  Equity-Based
Plans.  Any  beneficiary  so  designated by an  Independent  Board Member may be
changed at any time by notice in writing from such  Independent  Board Member to
the  Companies.  Payments  to a  beneficiary  shall  be made in a lump sum or in
installments,







<PAGE>



or both,  as  specified  in the  Independent  Board  Member's  Notice or amended
Notice.  If a lump sum is elected,  payment  shall be made as soon as reasonably
possible in the full and fractional  shares of the Company (and of any series of
such  Company) in which such Account is deemed  invested.  If  installments  are
elected,  such  installments  shall  be paid in cash in  amounts  determined  as
provided in section 9(a). If an Independent Board Member fails to designate in a
Notice or amended Notice on file with the Companies at the time of his death the
manner of distribution to his designated  beneficiary,  any distribution to such
beneficiary  (or if no such  beneficiary is designated,  to his estate) shall be
made in a lump sum. 10. PRIOR DEFERRALS.
                  Notwithstanding   anything  else   contained   herein  to  the
contrary,  if an  Independent  Board Member who is eligible to  participate in a
Plan under section 2 hereof has deferred any compensation  under any arrangement
in effect prior to the  establishment  of such Plan (i) such  Independent  Board
Member  shall be  deemed  to be a  participant  in such  Plan,  (ii) the  amount
credited for the benefit of such Independent Board Member under such arrangement
as of December  31, 1992 shall be credited to such  Independent  Board  Member's
Account







<PAGE>



under  such Plan as of  January  1, 1993 and (iii) the  provisions  of such Plan
shall apply to such  Independent  Board  Member and to the amount  described  in
subclause  (ii) above as though such amount had been deferred under the terms of
such Plan.  Elections  under  sections  6 or 8 by an  Independent  Board  Member
subject to the provisions of this section 10 shall govern any amounts  described
in this section. 11. STATEMENTS OF ACCOUNT.
                  Each Company will furnish each Independent Board Member with a
statement  setting forth the value of such  Independent  Board Member's  Account
under that  Company's  Plan and the value of each  portion of the  Account  that
relates to amounts  deferred under each subsection of section 3 as of the end of
each calendar year and all credits to and payments from such Account during such
year.  Such  statements will be furnished no later than 60 days after the end of
each calendar year. 12. RIGHTS IN ACCOUNTS.
                  Credits to Accounts and any shares  purchased by the Companies
to help satisfy the contractual  obligations with respect to such Accounts shall
remain part of the general assets of the Companies, shall at all times be the



<PAGE>



sole and absolute  property of the  Companies and shall in no event be deemed to
constitute a fund, trust or collateral  security for the payment of the deferred
compensation to which Independent Board Members are entitled from such Accounts.
The right of any  Independent  Board  Member or his  designated  beneficiary  or
estate to receive future payment of deferred  compensation  under the provisions
of  the  Plans  shall  be an  unsecured  claim  against  general  assets  of the
Companies, if any, available at the time of payment.
13.      NON-ASSIGNABILITY.
                  Neither  any   Independent   Board  Member,   his   designated
beneficiary  nor his  estate,  nor any  other  person  shall  have the  right to
encumber,  pledge,  sell, assign or transfer the right to receive payments under
the Plans,  except by will or by the laws of descent and distribution.  All such
payments and the right thereto are expressly declared to be non-assignable.  14.
ADMINISTRATION.
                  The  Equity-Based  Plans shall be  administered by one or more
officers  of  the  Companies   appointed  by  the  Compensation  and  Nominating
Committees of the Boards (the "Administrator"). All Notices and amendments shall
be filed with the Administrator and the Administrator shall be







<PAGE>



responsible for maintaining records of all Accounts and for
furnishing the annual statements of account provided for in
section 11.  The Administrator shall also have the general
authority to interpret, construe and implement provisions of
the Plans.  Any determination by such officer(s) shall be
binding on the Independent Board Member and shall be final
and conclusive.

15.      AMENDMENT OR TERMINATION.
                  The Equity-Based Plans may at any time be amended,
modified or terminated by the Board.  However, no amendment,
modification or termination shall adversely affect any
Independent Board Member's rights in respect of amounts
theretofore credited to his Accounts.

16.      EFFECTIVE DATE.
                  The  Equity-Based  Plans shall be  effective  as of January 1,
1993,  and any  amendments  hereto  shall be  effective  on the date of adoption
thereof by the Boards or as otherwise provided in such amendments.  The Deferred
Compensation  Plans in the  form  previously  adopted  by the  Companies  or the
arrangements  of the Companies for deferred  compensation in effect prior to the
establishment  of the  Equity-Based  Plans,  as the case may be, shall remain in
effect until January 1, 1993.

            Lord Abbett Research Fund, Inc. - Large-Cap Series -- Class C Shares
             -------------------------------------------------------------------



                  RULE 12b-1  DISTRIBUTION  PLAN AND AGREEMENT dated as of March
11, 1997 by and between LORD ABBETT RESEARCH FUND, INC., a Maryland corporation
(the  "Fund"),  and LORD ABBETT  DISTRIBUTOR  LLC, a New York limited  liability
company (the "Distributor").

                  WHEREAS, the Fund is an open-end management investment company
registered under the Investment Company Act of 1940, as amended (the "Act"); and
the  Distributor is the exclusive  selling agent of the Fund's Class C shares of
capital stock (the "Shares") pursuant to the Distribution  Agreement between the
Fund and the Distributor, dated as of the date hereof, and

                  WHEREAS,  the Fund  desires to adopt a  Distribution  Plan and
Agreement  (the "Plan") with the  Distributor,  as permitted by Rule 12b-1 under
the Act, pursuant to which the Fund may make certain payments to the Distributor
for payment to institutions and persons permitted by applicable law and/or rules
to receive such payments ("Authorized Institutions") in connection with sales of
Shares and for use by the  Distributor  as provided in paragraph 3 of this Plan,
and

                  WHEREAS,  the Fund's Board of Directors  has  determined  that
there is a  reasonable  likelihood  that the Plan will  benefit the Fund and the
holders of the Shares.

                  NOW,  THEREFORE,  in consideration of the mutual covenants and
of  other  good  and  valuable   consideration,   receipt  of  which  is  hereby
acknowledged, it is agreed as follows:

                  1. The Fund hereby  authorizes  the  Distributor to enter into
agreements with Authorized Institutions (the "Agreements") which may provide for
the payment to such Authorized  Institutions  of  distribution  and service fees
which the Distributor  receives from the Fund in order to provide  incentives to
such Authorized  Institutions (I) to sell Shares and (II) to provide  continuing
information  and  investment  services  to their  accounts  holding  Shares  and
otherwise  to encourage  their  accounts to remain  invested in the Shares.  The
Distributor  may, from time to time, waive or defer payment of some fees payable
at the time of the sale of Shares provided for under paragraph 2 hereof.

                  2.  Subject to possible  reduction  as provided  below in this
paragraph 2, the Fund shall pay to the Distributor  fees (I) at the time of sale
of Shares (A) for  services,  not to exceed .25 of 1% of the net asset  value of
the  Shares  sold and (B) for  distribution,  not to exceed .75 of 1% of the net
asset value of the Shares  sold;  and (II) at each  quarter-end  after the first
anniversary  of the sale of Shares (A) for  services,  at an annual  rate not to
exceed .25 of 1% of the average annual net asset value of Shares outstanding for
one year or more and (B) for  distribution,  at an annual rate not to exceed .75
of 1% of the average annual net asset value of Shares  outstanding  for one year
or more.  For purposes of clause (ii) above,  (A) Shares  issued  pursuant to an
exchange  for  Class C shares of  another  series  of the Fund or  another  Lord
Abbett-sponsored  fund (or for  shares of a fund  acquired  by the Fund) will be
credited with the time held from the initial  purchase of such other shares when
determining how long Shares  mentioned in clause (ii) have been  outstanding and
(B) payments will


<PAGE>



be based on Shares  outstanding  during  any such  quarter.  Sales in clause (i)
above exclude  Shares issued for  reinvested  dividends and  distributions,  and
Shares  outstanding  in clause (ii) above include  Shares issued for  reinvested
dividends and  distributions  which have been  outstanding for one year or more.
The  Board of  Directors  of the Fund  shall  from  time to time  determine  the
amounts,  within  the  foregoing  maximum  amounts,  that  the  Fund may pay the
Distributor  hereunder.  Such  determinations by the Board of Directors shall be
made by votes of the kind referred to in paragraph 10 of this Plan.  The service
fees mentioned in this  paragraph are for the purposes  mentioned in clause (ii)
of  paragraph  1 of  this  Plan  and the  distribution  fees  mentioned  in this
paragraph  are for the  purposes  mentioned in clause (i) of paragraph 1 and the
second  sentence of paragraph 3 of this Plan. The  Distributor  will monitor the
payments  hereunder  and shall reduce such  payments or take such other steps as
may be necessary to assure that (X) the payments  pursuant to this Plan shall be
consistent  with Article III,  Section 26,  subparagraphs  (d)(2) and (5) of the
Rules of Fair Practice of the National  Association of Securities Dealers,  Inc.
with respect to investment  companies with asset-based sales charges and service
fees as the same may be in effect  from time to time and (Y) the Fund  shall not
pay with respect to any Authorized  Institution  service fees equal to more than
 .25  of 1% of  the  average  annual  net  asset  value  of  Shares  sold  by (or
attributable  to  shares  sold by) such  Authorized  Institution  and held in an
account covered by an Agreement.

                  3. The  Distributor  may use amounts  received as distribution
fees hereunder from the Fund to finance any activity which is primarily intended
to result in the sale of Shares  including,  but not limited to,  commissions or
other payments  relating to selling or servicing  efforts.  Without limiting the
generality of the  foregoing,  the  Distributor  may apply up to 10 of the total
basis  points  authorized  by the Fund's Board of  Directors  designated  as the
distribution  fee  referred  to in clause  (ii)(b) of  paragraph  2 to  expenses
incurred by the Distributor if such expenses are primarily intended to result in
the sale of Shares. The Fund's Board of Directors (in the manner contemplated in
paragraph 10 of this Plan) shall approve the timing,  categories and calculation
of any  payments  under this  paragraph  3 other than those  referred  to in the
foregoing sentence.

                  4. The net asset value of the Shares  shall be  determined  as
provided in the Articles of Incorporation of the Fund. If the Distributor waives
all or a  portion  of  fees  which  are to be paid by the  Fund  hereunder,  the
Distributor  shall not be deemed to have waived its rights under this  Agreement
to have the Fund pay such fees in the future.

                  5. The  Secretary  of the Fund,  or in his  absence  the Chief
Financial Officer, is hereby authorized to direct the disposition of monies paid
or  payable by the Fund  hereunder  and shall  provide  to the  Fund's  Board of
Directors,  and the Board of  Directors  shall  review,  at least  quarterly,  a
written report of the amounts so expended pursuant to this Plan and the purposes
for which such expenditures were made.

                  6.  Neither  this Plan nor any other  transaction  between the
parties hereto pursuant to this Plan shall be invalidated or in any way affected
by the fact that any or all of the directors,  officers,  shareholders, or other
representatives  of  the  Fund  are  or  may  be  "interested  persons"  of  the
Distributor,  or any  successor or assignee  thereof,  or that any or all of the
directors,   officers,   partners,  members  or  other  representatives  of  the
Distributor are or may be "interested  persons" of the Fund, except as otherwise
may be provided in the Act.

                  7. The  Distributor  shall  give the Fund the  benefit  of the
Distributor's  best judgment and good faith efforts in rendering  services under
this Plan. Other than to abide by the provisions  hereof and render the services
called for hereunder in good faith,  the Distributor  assumes no  responsibility
under this Plan and, having so acted,  the Distributor  shall not be held liable
or held  accountable  for any mistake of law or fact,  or for any loss or damage
arising or resulting  therefrom suffered by the Fund or any of its shareholders,
creditors, directors or officers; provided however, that nothing herein shall be
deemed to protect  the  Distributor  against  any  liability  to the Fund or the
Fund's  shareholders  by  reason  of  willful  misfeasance,  bad  faith or gross
negligence  in the  performance  of its  duties  hereunder,  or by reason of the
reckless disregard of its obligations and duties hereunder.

                  8. This Plan shall become  effective  on the date hereof,  and
shall  continue in effect for a period of more than one year from such date only
so long as such continuance is specifically approved at least annually by a vote
of the Board of Directors of the Fund,  including  the vote of a majority of the
directors who are not "interested persons" of the Fund and who have no direct or
indirect  financial  interest in the  operation of this Plan or in any agreement
related to this  Plan,  cast in person at a meeting  called  for the  purpose of
voting on such renewal.

                  9. This Plan may not be amended  to  increase  materially  the
amount to be spent by the Fund  hereunder  without the vote of a majority of its
outstanding  voting securities and each material amendment must be approved by a
vote of the Board of Directors of the Fund,  including the vote of a majority of
the  directors  who are not  "interested  persons"  of the  Fund and who have no
direct or indirect  financial  interest in the  operation of this Plan or in any
agreement  related  to this  Plan,  cast in person at a meeting  called  for the
purpose of voting on such amendment.

                  10. Amendments to this Plan other than material  amendments of
the kind referred to in the foregoing paragraph 9 of this Plan may be adopted by
a vote of the Board of Directors of the Fund,  including  the vote of a majority
of the  directors who are not  "interested  persons" of the Fund and who have no
direct or indirect  financial  interest in the  operation of this Plan or in any
agreement  related to this Plan. The Board of Directors of the Fund may, by such
a vote,  interpret this Plan and make all determinations  necessary or advisable
for its administration.

                  11.  This  Plan  may be  terminated  at any time  without  the
payment of any  penalty by (A) the vote of a majority  of the  directors  of the
Fund who are not "interested persons" of the Fund and have no direct or indirect
financial  interest in the operation of this Plan or in any agreement related to
this Plan, or (B) by a shareholder  vote in compliance  with Rule 12b-1 and Rule
18f-3  under the Act as in effect at such time.  This Plan  shall  automatically
terminate in the event of its assignment.

                  12. So long as this Plan shall remain in effect, the selection
and nomination of those directors of the Fund who are not  "interested  persons"
of the Fund are committed to the discretion of such disinterested directors. The
terms  "interested  persons,"  "assignment"  and  "vote  of a  majority  of  the
outstanding  voting  securities"  shall have the same meaning as those terms are
defined in the Act.

                        Rule 12b-1 Distribution Plan and Agreement
          LORD ABBETT RESEARCH FUND, INC. -- SMALL-CAP SERIES -- CLASS A SHARES


                  RULE 12b-1  DISTRIBUTION  PLAN AND AGREEMENT  dated as of July
12, 1996 by and between LORD ABBETT RESEARCH FUND, INC., a Maryland  corporation
(the "Fund"), on behalf of its SMALL-CAP SERIES (the "Series"),  and LORD ABBETT
DISTRIBUTOR LLC, a New York limited liability company (the "Distributor").

                  WHEREAS, the Fund is an open-end management investment company
registered under the Investment Company Act of 1940, as amended (the "Act"); and
the  Distributor is the exclusive  selling agent of the Fund's shares of capital
stock,  including  the  Series'  Class A shares (the  "Shares")  pursuant to the
Distribution  Agreement  between the Fund and the  Distributor,  dated as of the
date hereof (the "Distribution Agreement").

                  WHEREAS,  the Fund  desires to adopt a  Distribution  Plan and
Agreement (the "Plan") for the Series with the Distributor, as permitted by Rule
12b-1 under the Act,  pursuant to which the Series may make certain  payments to
the  Distributor  to be used by the  Distributor  or  paid to  institutions  and
persons  permitted  by  applicable  law and/or  rules to receive  such  payments
("Authorized  Institutions") in connection with sales of Shares and/or servicing
of accounts of shareholders holding Shares.

                  WHEREAS,  the Fund's Board of Directors  has  determined  that
there is a reasonable  likelihood  that the Plan will benefit the Series and the
holders of the Shares.

                  NOW,  THEREFORE,  in consideration of the mutual covenants and
of  other  good  and  valuable   consideration,   receipt  of  which  is  hereby
acknowledged, it is agreed as follows:

                  1. The Fund hereby  authorizes  the  Distributor to enter into
agreements with Authorized Institutions (the "Agreements") which may provide for
the payment to such Authorized  Institutions  of  distribution  and service fees
which the  Distributor  receives from the Series in order to provide  additional
incentives  to such  Authorized  Institutions  (I) to sell  Shares  and  (II) to
provide continuing information and investment services to their accounts holding
Shares and  otherwise  to  encourage  their  accounts to remain  invested in the
Shares.

                  2. The Fund also  hereby  authorizes  the  Distributor  to use
payments received hereunder from the Series in order to (A) finance any activity
which is  primarily  intended  to result in the sale of Shares  and (B)  provide
continuing  information  and  investment  services to  shareholder  accounts not
serviced by Authorized Institutions







<PAGE>



receiving  a  service  fee from  the  Distributor  hereunder  and  otherwise  to
encourage such accounts to remain invested in the Shares;  PROVIDED that (I) any
payments  referred  to  in  the  foregoing  clause  (a)  shall  not  exceed  the
distribution fee permitted to be paid at the time under paragraph 3 of this Plan
and shall be  authorized  by the Board of Directors of the Fund by a vote of the
kind referred to in paragraph 10 of this Plan and (II) any payments  referred to
in clause (b) shall not exceed the service fee  permitted to be paid at the time
under paragraph 3 of this Plan.

                  3. The Series is authorized to pay the  Distributor  hereunder
for remittance to Authorized Institutions and/or use by the Distributor pursuant
to this Plan (A) service fees and (B) distribution  fees, each at an annual rate
not to  exceed  .25 of 1% of the  average  annual  net  asset  value  of  Shares
outstanding.  The  Board  of  Directors  of the  Fund  shall  from  time to time
determine the amounts, within the foregoing maximum amounts, that the Series may
pay the  Distributor  hereunder.  Any such  fees  (which  may be  waived  by the
Authorized  Institutions  in  whole  or in  part)  may be  calculated  and  paid
quarterly or more  frequently if approved by the Board of Directors of the Fund.
Such  determinations  and approvals by the Board of Directors  shall be made and
given by votes of the kind referred to in paragraph 10 of this Plan. Payments by
holders of Shares to the Series of  contingent  deferred  reimbursement  charges
relating to  distribution  fees paid by the Series  hereunder  shall  reduce the
amount of distribution  fees for purposes of the annual 0.25%  distribution  fee
limit. The Distributor will monitor the payments hereunder and shall reduce such
payments  or take such other  steps as may be  necessary  to assure that (I) the
payments pursuant to this Plan shall be consistent with Article III, Section 26,
subparagraphs  (d)(2)  and (5) of the  Rules of Fair  Practice  of the  National
Association  of Securities  Dealers,  Inc. with respect to investment  companies
with  asset-based  sales  charges and service fees, as the same may be in effect
from  time to time  and (II)  the  Series  shall  not pay  with  respect  to any
Authorized  Institution service fees equal to more than .25 of 1% of the average
annual net asset  value of Shares sold by (or  attributable  to Shares or shares
sold by)  such  Authorized  Institution  and held in an  account  covered  by an
Agreement.

                  4. The net asset value of the Shares  shall be  determined  as
provided in the Articles of Incorporation of the Fund. If the Distributor waives
all or a portion of the fees which are to be paid by the Series  hereunder,  the
Distributor  shall not be deemed to have waived its rights under this  Agreement
to have the Series pay such fees in the future.

                  5. The  Secretary  of the Fund,  or in his  absence  the Chief
Financial Officer, is hereby authorized to direct the disposition of monies paid
or payable  by the Series  hereunder  and shall  provide to the Fund's  Board of
Directors,  and the directors shall review at least quarterly,  a written report
of the amounts so expended pursuant to this Plan and the purposes for which such
expenditures were made.







<PAGE>



                  6.  Neither  this Plan nor any other  transaction  between the
parties hereto pursuant to this Plan shall be invalidated or in any way affected
by the fact that any or all of the directors,  officers,  shareholders, or other
representatives  of  the  Fund  are  or  may  be  "interested  persons"  of  the
Distributor,  or any  successor or assignee  thereof,  or that any or all of the
directors,   officers,   partners,  members  or  other  representatives  of  the
Distributor  are or may be  "interested  persons"  of the  Fund,  except  as may
otherwise be provided in the Act.

                  7. The  Distributor  shall  give the Fund the  benefit  of the
Distributor's  best judgment and good faith efforts in rendering  services under
this Plan. Other than to abide by the provisions  hereof and render the services
called for hereunder in good faith,  the Distributor  assumes no  responsibility
under this Plan and, having so acted,  the Distributor  shall not be held liable
or held  accountable  for any mistake of law or fact,  or for any loss or damage
arising or resulting  therefrom  suffered by the Fund,  the Series or any of the
shareholders,  creditors,  directors, or officers of the Fund; provided however,
that  nothing  herein  shall be deemed to protect  the  Distributor  against any
liability  to  the  Fund  or the  Series'  shareholders  by  reason  of  willful
misfeasance,  bad faith or gross  negligence  in the  performance  of its duties
hereunder,  or by reason of the reckless disregard of its obligations and duties
hereunder.

                  8. This Plan shall become effective upon the date hereof,  and
shall  continue in effect for a period of more than one year from that date only
so long as such continuance is specifically approved at least annually by a vote
of the Board of Directors of the Fund,  including  the vote of a majority of the
directors who are not "interested persons" of the Fund and who have no direct or
indirect  financial  interest in the  operation of this Plan or in any agreement
related to this  Plan,  cast in person at a meeting  called  for the  purpose of
voting on such renewal.

                  9. This Plan may not be amended  to  increase  materially  the
amount to be spent by the Series hereunder above the maximum amounts referred to
in paragraph 3 of this Plan without a shareholder  vote in compliance  with Rule
12b-1 and Rule 18f-3 under the Act as in effect at such time,  and each material
amendment  must be  approved  by a vote of the Board of  Directors  of the Fund,
including  the  vote of a  majority  of the  directors  who are not  "interested
persons"  of the Fund and who have no direct or indirect  financial  interest in
the  operation of this Plan or in any  agreement  related to this Plan,  cast in
person  at a  meeting  called  for the  purpose  of  voting  on such  amendment.
Amendments to this Plan which do not increase  materially the amount to be spent
by the Series  hereunder above the maximum amounts referred to in paragraph 3 of
this Plan may be made pursuant to paragraph 10 of this Plan.

                   10. Amendments to this Plan other than material amendments of
the kind referred to in the foregoing paragraph 9 may be adopted by a vote of
the Board of

<PAGE>



Directors of the Fund, including the vote of a majority of the directors who are
not  "interested  persons"  of the  Fund  and who  have no  direct  or  indirect
financial  interest in the operation of this Plan or in any agreement related to
this Plan.  The Board of  Directors  of the Fund may, by such a vote,  interpret
this  Plan  and  make  all   determinations   necessary  or  advisable  for  its
administration.

                  11.  This  Plan  may be  terminated  at any time  without  the
payment of any  penalty (A) by the vote of a majority  of the  directors  of the
Fund who are not "interested persons" of the Fund and have no direct or indirect
financial  interest in the operation of this Plan or in any agreement related to
the Plan,  or (B) by a shareholder  vote in compliance  with Rule 12b-1 and Rule
18f-3 under the Act as in effect at such time.

                  12. So long as this Plan shall remain in effect, the selection
and nomination of those directors of the Fund who are not  "interested  persons"
of the Fund are committed to the discretion of such disinterested directors. The

            LORD ABBETT RESEARCH FUND, INC.-- SMALL-CAP SERIES-- CLASS B SHARES


         RULE 12b-1 DISTRIBUTION PLAN AND AGREEMENT dated as of July 12, 1996 by
and  between  LORD ABBETT  RESEARCH  FUND,  INC.,  a Maryland  Corporation  (the
"Fund"),  on behalf of its  SMALL-CAP  SERIES  (the  "Series"),  and LORD ABBETT
DISTRIBUTOR LLC, a New York limited liability company (the "Distributor").

         WHEREAS,  the  Fund  is  an  open-end  management   investment  company
registered under the Investment Company Act of 1940, as amended (the "Act"); and
the  Distributor is the exclusive  selling agent of the Fund's shares of capital
stock  including  the  Series  Class B shares  (the  "Shares")  pursuant  to the
Distribution  Agreement  between the Fund and the  Distributor,  dated as of the
date hereof, and

         WHEREAS,  the Fund desires to adopt a  Distribution  Plan and Agreement
(the  "Plan")  with the  Distributor,  as permitted by Rule 12b-1 under the Act,
pursuant to which the Series may make certain payments to the Distributor (a) to
help  reimburse  the  Distributor  for  the  payment  of  sales  commissions  to
institutions  and persons  permitted by  applicable  law and/or rules to receive
such payments ("Authorized Institutions") in connection with sales of Shares and
(b) for use by the  Distributor  in rendering  service to the Series,  including
paying and financing the payment of sales  commissions,  service fees, and other
costs of  distributing  and selling  Shares as  provided in  paragraph 3 of this
Plan, and

         WHEREAS,  the Fund's Board of Directors has determined  that there is a
reasonable  likelihood  that the Plan will benefit the Series and the holders of
the Shares.

         NOW,  THEREFORE,  in consideration of the mutual covenants and of other
good and valuable consideration,  receipt of which is hereby acknowledged, it is
agreed as follows:

         1. The Fund hereby  authorizes the Distributor to enter into agreements
with  Authorized  Institutions  (the  "Agreements")  which may  provide  for the
payment to such Authorized  Institutions of (a) sales commissions  (particularly
those paid or financed with payments  received  hereunder)  and (b) service fees
received   hereunder  in  order  to  provide   incentives  to  such   Authorized
Institutions (i) to sell Shares and (ii) to provide  continuing  information and
investment  services to their accounts holding Shares and otherwise to encourage
their accounts to remain invested in the Shares,  respectively.  The Distributor
may, from time to time,  waive or defer payment of some fees payable at the time
of the sale of Shares provided for under paragraph 2 hereof.

         2. Subject to possible  reductions as provided  below in this paragraph
2, the Series  periodically,  as determined by the Fund's Board of Directors (in
the manner  contemplated in paragraph 11), shall pay to the Distributor fees (a)
for  services,  at an annual rate not to exceed .25 of 1% of the average  annual
net asset value of Shares  outstanding  and (b) for  distribution,  at an annual
rate not to exceed .75 of 1% of the  average  annual  net asset  value of Shares
outstanding.  Payments  will be  based on  Shares  outstanding  during  any such
period. Shares outstanding include

                                                         1

Shares issued for reinvested dividends and distributions. The Board of Directors
of the Fund shall from time to time determine the amounts,  within the foregoing
maximum  amounts,  that  the  Series  may pay the  Distributor  hereunder.  Such
determinations  by the  Board  of  Directors  shall be made by votes of the kind
referred to in  paragraph 11 of this Plan.  The service  fees  mentioned in this
paragraph  are for the  purposes  mentioned in clause (b) (ii) of paragraph 1 of
this Plan and the  distribution  fees  mentioned in this  paragraph  are for the
purposes  mentioned  in  clause  (b)  (i)  of  paragraph  1 of  this  Plan.  The
Distributor  will monitor the payments  hereunder and shall reduce such payments
or take such other steps as may be  necessary  to assure  that (x) the  payments
pursuant  to this  Plan  shall be  consistent  with  Article  III,  Section  26,
subparagraphs  (d)(2)  and (5) of the  Rules of Fair  Practice  of the  National
Association  of Securities  Dealers,  Inc. with respect to investment  companies
with  asset-based  sales  charges and service  fees as the same may be in effect
from time to time and (y) the Fund shall not pay with respect to any  Authorized
Institution  service fees equal to more than .25 of 1% of the average annual net
asset  value  of  Shares  sold by (or  attributable  to  shares  sold  by)  such
Authorized Institution and held in an account covered by an Agreement.

         3. The  Distributor  may use  amounts  received  as  distribution  fees
hereunder  from the Fund to engage  directly  or  indirectly  in  financing  any
activity which is primarily  intended to result in the sale of Shares including,
but not limited to: (a) paying and financing the payment of commissions or other
payments  relating  to selling or  servicing  efforts  and (b) paying  interest,
carrying,  or any other financing  charges on any  unreimbursed  distribution or
other expense  incurred in a prior fiscal year of the Series whether or not such
charges and  unreimbursed  distribution  or other expense are determined to be a
legal  obligation  of the  Fund,  in whole or in part,  by the  Fund's  Board of
Directors.  The  Fund's  Board  of  Directors  (in the  manner  contemplated  in
paragraph 11 of this Plan) shall approve the timing,  categories and calculation
of any payments under this paragraph 3.

         4.1.  The Fund will pay each person which has acted as  Distributor  of
Shares its Allocable Portion (as such term is defined in paragraphs 13.1 through
13.3)  of the  distribution  fees  with  respect  to  Shares  of the  Series  in
consideration  of its  services as principal  underwriter  for the Shares of the
Fund.  The  Distribution  Agreement  pursuant to which a person acts or acted as
principal   underwriter  of  the  Shares  is  referred  to  as  the  "Applicable
Distribution Agreement". Such person shall be paid its Allocable Portion of such
distribution fees  notwithstanding  such person's  termination as Distributor of
the Shares,  such payments to be changed or terminated only (i) as required by a
change  in  applicable  law or a change  in  accounting  policy  adopted  by the
Investment Companies Committee of the AICPA and approved by FASB that results in
a determination by the Fund's independent  accountants that any sales charges in
respect of such Fund, which are not contingent  deferred sales charges and which
are not yet due and payable,  must be accounted  for by such Fund as a liability
in  accordance  with  GAAP,  each  after  the  effective  date of this  Plan and
restatement; (ii) if in the sole discretion of the Board of Directors, after due
consideration  of  such  factors  as they  considered  relevant,  including  the
transactions  contemplated  in any  purchase  and sale  agreement  entered  into
between the Series Distributor and any commission financing entity, the Board of
Directors  determines  (in the manner  contemplated  in  paragraph  12),  in the
exercise of its fiduciary duty, that this Plan and the payments  thereunder must
be changed or terminated,  notwithstanding  the effect this action might have on
the  Fund's  ability to offer and sell  Shares;  or (iii) in  connection  with a
Complete  Termination of this Plan, it being  understood that for this purpose a
Complete

                                                         2

Termination of this Plan occurs only if this Plan is terminated and the Fund has
discontinued  the distribution of Shares or other back-end load or substantially
similar classes of shares;  it being understood that such does not include Class
C shares,  I.E.,  those  sold with a level  load.  The  services  rendered  by a
Distributor  for which that  Distributor  is entitled  to receive its  Allocable
Portion of the  distribution  fee shall be deemed to have been  completed at the
time of the  initial  purchase  of the  Shares  (as  defined  in the  Applicable
Distribution  Agreement)  (whether  of that Fund or  another  fund)  taken  into
account in computing that  Distributor's  Allocable  Portion of the distribution
fee.

         4.2.     The obligation of the Fund to pay the distribution fee shall 
terminate upon the termination of this Plan in accordance with the terms hereof.

         4.3. The right of a Distributor  to receive  payments  hereunder may be
transferred by that Distributor  (but not the  distribution  agreement itself or
that Distributor's  obligations thereunder) in order to raise funds which may be
useful or necessary to perform its duties as principal underwriter, and any such
transfer  shall be effective  upon written  notice from that  Distributor to the
Fund. In connection  with the foregoing,  the Series is authorized to pay all or
part of the  distribution  fee and/or  contingent  deferred  sales  charges with
respect to Shares (upon the terms and  conditions  set forth in the then current
Fund prospectus) directly to such transferee as directed by that Distributor.

         4.4. As long as this Plan is in effect, the Series shall not change the
manner in which the distribution fee is computed (except as may be required by a
change  in  applicable  law or a change  in  accounting  policy  adopted  by the
Investment Companies Committee of the AICPA and approved by FASB that results in
a determination by the Fund's independent accountants that any distribution fees
which  are not yet due and  payable,  must be  accounted  for by such  Fund as a
liability in accordance with GAAP).

         5. The net asset value of the Shares shall be determined as provided in
the Articles of  Incorporation  of the Fund. If the Distributor  waives all or a
portion of fees which are to be paid by the Series  hereunder,  the  Distributor
shall not be deemed to have waived its rights  under this  Agreement to have the
Series pay such fees in the future.

         6. The  Secretary  of the Fund,  or in his absence the Chief  Financial
Officer,  is hereby  authorized  to direct  the  disposition  of monies  paid or
payable  by the  Fund  hereunder  and  shall  provide  to the  Fund's  Board  of
Directors,  and the Board of  Directors  shall  review,  at least  quarterly,  a
written report of the amounts so expended pursuant to this Plan and the purposes
for which such  expenditures were made. Over the long-term the expenses incurred
by the Distributor for engaging directly or indirectly in financing any activity
which is  primarily  intended  to result in the sale of Shares  are likely to be
greater then the  distribution  fees  receivable by the  Distributor  hereunder.
Nevertheless,  there exists the  possibility  that for a  short-term  period the
Distributor  may not  have a  sufficient  amount  of such  expenses  to  warrant
reimbursement  by receipt of such  distribution  fees.  Although the Distributor
undertakes  not to make a profit under this Plan,  the Plan will be considered a
compensation  plan (i.e.  distribution  fees will be paid regardless of expenses
incurred) in order to avoid the possibility of the Distributor not being able to
receive such distribution fees because of a temporary timing difference  between
its incurring such expenses and the receipt of such distribution fees.

         7. Neither this Plan nor any other transaction between the Fund and the
Distributor,  or any successor or assignee thereof,  pursuant to this Plan shall
be  invalidated  or in any  way  affected  by the  fact  that  any or all of the
directors,  officers,  shareholders, or other representatives of the Fund are or
may be  "interested  persons" of the  Distributor,  or any successor or assignee
thereof,  or that any or all of the directors,  officers,  partners,  members or
other  representatives of the Distributor are or may be "interested  persons" of
the Fund, except as otherwise may be provided in the Act.

         8. The Distributor shall give the Fund the benefit of the Distributor's
best  judgment  and good faith  efforts in rendering  services  under this Plan.
Other than to abide by the provisions  hereof and render the services called for
hereunder in good faith, the Distributor  assumes no  responsibility  under this
Plan and,  having so acted,  the  Distributor  shall not be held  liable or held
accountable for any mistake of law or fact, or for any loss or damage arising or
resulting therefrom suffered by the Fund or any of its shareholders,  creditors,
directors or officers;  provided however, that nothing herein shall be deemed to
protect  the  Distributor  against  any  liability  to the  Fund  or the  Series
shareholders by reason of willful misfeasance,  bad faith or gross negligence in
the performance of its duties hereunder,  or by reason of the reckless disregard
of its obligations and duties hereunder.

         9. This Plan  shall  become  effective  on the date  hereof,  and shall
continue  in  effect  for a period  of more than one year from such date only so
long as such continuance is specifically approved at least annually by a vote of
the Board of  Directors  of the Fund,  including  the vote of a majority  of the
directors who are not "interested persons" of the Fund and who have no direct or
indirect  financial  interest in the  operation of this Plan or in any agreement
related to this  Plan,  cast in person at a meeting  called  for the  purpose of
voting on such renewal.

         10. This Plan may not be amended to increase  materially  the amount to
be  spent  by the  Series  hereunder  without  the  vote  of a  majority  of its
outstanding  voting securities and each material amendment must be approved by a
vote of the Board of Directors of the Fund,  including the vote of a majority of
the  directors  who are not  "interested  persons"  of the  Fund and who have no
direct or indirect  financial  interest in the  operation of this Plan or in any
agreement  related  to this  Plan,  cast in person at a meeting  called  for the
purpose of voting on such amendment.

         11. Amendments to this Plan other than material  amendments of the kind
referred to in the foregoing  paragraph 10 of this Plan may be adopted by a vote
of the Board of Directors of the Fund,  including  the vote of a majority of the
directors who are not "interested persons" of the Fund and who have no direct or
indirect  financial  interest in the  operation of this Plan or in any agreement
related to this Plan.  The Board of  Directors  of the Fund may, by such a vote,
interpret this Plan and make all  determinations  necessary or advisable for its
administration.

         12. This Plan may be  terminated at any time without the payment of any
penalty by (a) the vote of a majority of the  directors  of the Fund who are not
"interested  persons"  of the Fund  and have no  direct  or  indirect  financial
interest in the operation of this Plan or in any agreement related to this Plan,
or (b) by a shareholder  vote in compliance with Rule 12b-1 and Rule 18f-3 under
the Act as in effect at such time.  This Plan shall  automatically  terminate in
the event of its assignment.

         13.1.    For purposes of this Plan, the Distributor's "Allocable
                  Portion" of the distribution fee

                                                         4

<PAGE>



shall  be 100% of such  distribution  fees  unless  or  until  the  Fund  uses a
principal  underwriter  other than the  Distributor.  Thereafter  the  Allocable
Portion shall be the portion of the  distribution fee attributable to (i) Shares
of  the  Series  sold  by  the  Distributor  before  there  is a  new  principal
underwriter,  plus (ii)  Shares of the  Series  issued  in  connection  with the
exchange of Shares of another  Fund in the Lord,  Abbett  Family of Funds,  plus
(iii)  Shares  of the  Series  issued in  connection  with the  reinvestment  of
dividends and capital gains.

         13.2. The Distributor's  Allocable Portion of the distribution fees and
the contingent  deferred sales charges arising with respect to Shares taken into
account in computing the Distributor's  Allocable Portion shall be limited under
Article  III,  Sections  26(b) and (d) or other  applicable  regulations  of the
National  Association of Securities Dealers,  Inc. (the "NASD") as if the Shares
taken into account in computing the Distributor's  Allocable Portion  themselves
constituted a separate class of shares of the Fund.

         13.3.  The  services   rendered  by  the   Distributor  for  which  the
Distributor is entitled to receive the  Distributor's  Allocable  Portion of the
distribution  fees  shall be deemed to have  been  completed  at the time of the
initial  purchase  of the Shares (or shares of another  Fund in the Lord  Abbett
Family of Funds)  taken into account in computing  the  Distributor's  Allocable
Portion.  In addition,  the Series will pay to the  Distributor  any  contingent
deferred  sales  charges  imposed on  redemption  of Shares  (upon the terms and
conditions set forth in the then current Fund prospectus)  taken into account in
computing  the  Distributor's   Allocable  Portion  of  the  distribution  fees.
Notwithstanding  anything to the contrary in this Plan, the Distributor shall be
paid  its  Allocable   Portion  of  the  distribution  fees  regardless  of  the
Distributor's  termination as principal underwriter of the Shares of the Series,
or any  termination of this Agreement  other than in connection  with a Complete
Termination  (as defined in paragraph  4.1) of the Plan as in effect on the date
of execution  of  Distribution  Agreement  with the new  Distributor.  Except as
provided in paragraph 4.1 and in the preceding  sentence,  the Series obligation
to  pay  the  distribution  fees  to  the  Distributor  shall  be  absolute  and
unconditional and shall not be subject to any dispute,  offset,  counterclaim or
defense  whatsoever (it being  understood that nothing in this sentence shall be
deemed a waiver by the  Series of its right  separately  to pursue any claims it
may have against the  Distributor  and to enforce such claims against any assets
of the  Distributor  (other  than the assets  represented  by the  Distributor's
rights to be paid its Allocable  Portion of the distribution fees and to be paid
the contingent deferred sales charges).


         14. So long as this Plan shall  remain in  effect,  the  selection  and
nomination of those  directors of the Fund who are not  "interested  persons" of
the Fund are committed to the discretion of such  disinterested  directors.  The
terms  "interested  persons,"  "assignment"  and  "vote  of a  majority  of  the
outstanding  voting  securities"  shall have the same meaning as those terms are
defined in the Act.

                        Rule 12b-1 Distribution Plan and Agreement
            Lord Abbett Research Fund, Inc. - Small-Cap Series -- Class C Shares
             -------------------------------------------------------------------


                  RULE 12b-1  DISTRIBUTION  PLAN AND AGREEMENT dated as of March
11, 1997 by and between LORD ABBETT RESEARCH FUND, INC., a Maryland corporation
(the  "Fund"),  and LORD ABBETT  DISTRIBUTOR  LLC, a New York limited  liability
company (the "Distributor").

                  WHEREAS, the Fund is an open-end management investment company
registered under the Investment Company Act of 1940, as amended (the "Act"); and
the  Distributor is the exclusive  selling agent of the Fund's Class C shares of
capital stock (the "Shares") pursuant to the Distribution  Agreement between the
Fund and the Distributor, dated as of the date hereof, and

                  WHEREAS,  the Fund  desires to adopt a  Distribution  Plan and
Agreement  (the "Plan") with the  Distributor,  as permitted by Rule 12b-1 under
the Act, pursuant to which the Fund may make certain payments to the Distributor
for payment to institutions and persons permitted by applicable law and/or rules
to receive such payments ("Authorized Institutions") in connection with sales of
Shares and for use by the  Distributor  as provided in paragraph 3 of this Plan,
and

                  WHEREAS,  the Fund's Board of Directors  has  determined  that
there is a  reasonable  likelihood  that the Plan will  benefit the Fund and the
holders of the Shares.

                  NOW,  THEREFORE,  in consideration of the mutual covenants and
of  other  good  and  valuable   consideration,   receipt  of  which  is  hereby
acknowledged, it is agreed as follows:

                  1. The Fund hereby  authorizes  the  Distributor to enter into
agreements with Authorized Institutions (the "Agreements") which may provide for
the payment to such Authorized  Institutions  of  distribution  and service fees
which the Distributor  receives from the Fund in order to provide  incentives to
such Authorized  Institutions (I) to sell Shares and (II) to provide  continuing
information  and  investment  services  to their  accounts  holding  Shares  and
otherwise  to encourage  their  accounts to remain  invested in the Shares.  The
Distributor  may, from time to time, waive or defer payment of some fees payable
at the time of the sale of Shares provided for under paragraph 2 hereof.

                  2.  Subject to possible  reduction  as provided  below in this
paragraph 2, the Fund shall pay to the Distributor  fees (I) at the time of sale
of Shares (A) for  services,  not to exceed .25 of 1% of the net asset  value of
the  Shares  sold and (B) for  distribution,  not to exceed .75 of 1% of the net
asset value of the Shares  sold;  and (II) at each  quarter-end  after the first
anniversary  of the sale of Shares (A) for  services,  at an annual  rate not to
exceed .25 of 1% of the average annual net asset value of Shares outstanding for
one year or more and (B) for  distribution,  at an annual rate not to exceed .75
of 1% of the average annual net asset value of Shares  outstanding  for one year
or more.  For purposes of clause (ii) above,  (A) Shares  issued  pursuant to an
exchange  for  Class C shares of  another  series  of the Fund or  another  Lord
Abbett-sponsored  fund (or for  shares of a fund  acquired  by the Fund) will be
credited with the time held from the initial  purchase of such other shares when
determining how long Shares  mentioned in clause (ii) have been  outstanding and
(B) payments will


<PAGE>



be based on Shares  outstanding  during  any such  quarter.  Sales in clause (i)
above exclude  Shares issued for  reinvested  dividends and  distributions,  and
Shares  outstanding  in clause (ii) above include  Shares issued for  reinvested
dividends and  distributions  which have been  outstanding for one year or more.
The  Board of  Directors  of the Fund  shall  from  time to time  determine  the
amounts,  within  the  foregoing  maximum  amounts,  that  the  Fund may pay the
Distributor  hereunder.  Such  determinations by the Board of Directors shall be
made by votes of the kind referred to in paragraph 10 of this Plan.  The service
fees mentioned in this  paragraph are for the purposes  mentioned in clause (ii)
of  paragraph  1 of  this  Plan  and the  distribution  fees  mentioned  in this
paragraph  are for the  purposes  mentioned in clause (i) of paragraph 1 and the
second  sentence of paragraph 3 of this Plan. The  Distributor  will monitor the
payments  hereunder  and shall reduce such  payments or take such other steps as
may be necessary to assure that (X) the payments  pursuant to this Plan shall be
consistent  with Article III,  Section 26,  subparagraphs  (d)(2) and (5) of the
Rules of Fair Practice of the National  Association of Securities Dealers,  Inc.
with respect to investment  companies with asset-based sales charges and service
fees as the same may be in effect  from time to time and (Y) the Fund  shall not
pay with respect to any Authorized  Institution  service fees equal to more than
 .25  of 1% of  the  average  annual  net  asset  value  of  Shares  sold  by (or
attributable  to  shares  sold by) such  Authorized  Institution  and held in an
account covered by an Agreement.

                  3. The  Distributor  may use amounts  received as distribution
fees hereunder from the Fund to finance any activity which is primarily intended
to result in the sale of Shares  including,  but not limited to,  commissions or
other payments  relating to selling or servicing  efforts.  Without limiting the
generality of the  foregoing,  the  Distributor  may apply up to 10 of the total
basis  points  authorized  by the Fund's Board of  Directors  designated  as the
distribution  fee  referred  to in clause  (ii)(b) of  paragraph  2 to  expenses
incurred by the Distributor if such expenses are primarily intended to result in
the sale of Shares. The Fund's Board of Directors (in the manner contemplated in
paragraph 10 of this Plan) shall approve the timing,  categories and calculation
of any  payments  under this  paragraph  3 other than those  referred  to in the
foregoing sentence.

                  4. The net asset value of the Shares  shall be  determined  as
provided in the Articles of Incorporation of the Fund. If the Distributor waives
all or a  portion  of  fees  which  are to be paid by the  Fund  hereunder,  the
Distributor  shall not be deemed to have waived its rights under this  Agreement
to have the Fund pay such fees in the future.

                  5. The  Secretary  of the Fund,  or in his  absence  the Chief
Financial Officer, is hereby authorized to direct the disposition of monies paid
or  payable by the Fund  hereunder  and shall  provide  to the  Fund's  Board of
Directors,  and the Board of  Directors  shall  review,  at least  quarterly,  a
written report of the amounts so expended pursuant to this Plan and the purposes
for which such expenditures were made.

                  6.  Neither  this Plan nor any other  transaction  between the
parties hereto pursuant to this Plan shall be invalidated or in any way affected
by the fact that any or all of the directors,  officers,  shareholders, or other
representatives  of  the  Fund  are  or  may  be  "interested  persons"  of  the
Distributor,  or any  successor or assignee  thereof,  or that any or all of the
directors,   officers,   partners,  members  or  other  representatives  of  the
Distributor are or may be "interested  persons" of the Fund, except as otherwise
may be provided in the Act.

                  7. The  Distributor  shall  give the Fund the  benefit  of the
Distributor's  best judgment and good faith efforts in rendering  services under
this Plan. Other than to abide by the provisions  hereof and render the services
called for hereunder in good faith,  the Distributor  assumes no  responsibility
under this Plan and, having so acted,  the Distributor  shall not be held liable
or held  accountable  for any mistake of law or fact,  or for any loss or damage
arising or resulting  therefrom suffered by the Fund or any of its shareholders,
creditors, directors or officers; provided however, that nothing herein shall be
deemed to protect  the  Distributor  against  any  liability  to the Fund or the
Fund's  shareholders  by  reason  of  willful  misfeasance,  bad  faith or gross
negligence  in the  performance  of its  duties  hereunder,  or by reason of the
reckless disregard of its obligations and duties hereunder.

                  8. This Plan shall become  effective  on the date hereof,  and
shall  continue in effect for a period of more than one year from such date only
so long as such continuance is specifically approved at least annually by a vote
of the Board of Directors of the Fund,  including  the vote of a majority of the
directors who are not "interested persons" of the Fund and who have no direct or
indirect  financial  interest in the  operation of this Plan or in any agreement
related to this  Plan,  cast in person at a meeting  called  for the  purpose of
voting on such renewal.

                  9. This Plan may not be amended  to  increase  materially  the
amount to be spent by the Fund  hereunder  without the vote of a majority of its
outstanding  voting securities and each material amendment must be approved by a
vote of the Board of Directors of the Fund,  including the vote of a majority of
the  directors  who are not  "interested  persons"  of the  Fund and who have no
direct or indirect  financial  interest in the  operation of this Plan or in any
agreement  related  to this  Plan,  cast in person at a meeting  called  for the
purpose of voting on such amendment.

                  10. Amendments to this Plan other than material  amendments of
the kind referred to in the foregoing paragraph 9 of this Plan may be adopted by
a vote of the Board of Directors of the Fund,  including  the vote of a majority
of the  directors who are not  "interested  persons" of the Fund and who have no
direct or indirect  financial  interest in the  operation of this Plan or in any
agreement  related to this Plan. The Board of Directors of the Fund may, by such
a vote,  interpret this Plan and make all determinations  necessary or advisable
for its administration.

                  11.  This  Plan  may be  terminated  at any time  without  the
payment of any  penalty by (A) the vote of a majority  of the  directors  of the
Fund who are not "interested persons" of the Fund and have no direct or indirect
financial  interest in the operation of this Plan or in any agreement related to
this Plan, or (B) by a shareholder  vote in compliance  with Rule 12b-1 and Rule
18f-3  under the Act as in effect at such time.  This Plan  shall  automatically
terminate in the event of its assignment.

                  12. So long as this Plan shall remain in effect, the selection
and nomination of those directors of the Fund who are not  "interested  persons"
of the Fund are committed to the discretion of such disinterested directors. The
terms  "interested  persons,"  "assignment"  and  "vote  of a  majority  of  the
outstanding  voting  securities"  shall have the same meaning as those terms are
defined in the Act.

                 Amended and Restated Plans as of March __,1997

                  Rule 18f-3 (the "Rule")  under the  Investment  Company Act of
1940,  as amended  (the "1940  Act"),  requires  that the Board of  Directors or
Trustees of an investment company desiring to offer multiple classes pursuant to
the Rule  adopt a plan  setting  forth  the  separate  arrangement  and  expense
allocation  of each  class,  and any  related  conversion  features  or exchange
privileges.   This   document   constitutes   an  amended  and   restated   plan
(individually, a "Plan" and collectively, the "Plans") of each of the investment
companies,  or series  thereof,  listed on Schedule A attached  hereto (each,  a
"Fund").  The Plan of any Fund is subject to amendment by action of the Board of
Directors  or Trustees  (the  "Board") of such Fund and without the  approval of
shareholders of any class,  to the extent  permitted by law and by the governing
documents of such Fund.
                  The Board,  including a majority of the non-in  terested Board
members,  has determined  that the following  separate  arrangement  and expense
allocation,   and  the  related  conversion  features,   if  any,  and  exchange
privileges, of each class of each Fund are in the best interest of each class of
each Fund individually and each Fund as a whole.

shall be  divided  into  Class A  shares,  Class B shares  and Class C shares as
indicated for each Fund on Schedule A attached  hereto.  In the case of the Lord
Abbett  Series Fund - Growth & Income  Portfolio,  shares  shall be divided into
Variable Contract Class shares and Pension Class shares as indicated on Schedule
A.

2.       SALES CHARGES AND DISTRIBUTION AND SERVICE FEES.
                  (a) INITIAL SALES CHARGE.  Class A shares will be  traditional
front-end  sales charge shares,  offered at their net asset value ("NAV") plus a
sales charge in the case of each Fund as described in such Fund's  prospectus as
from time to time in effect.
                  Class B shares, Class C shares, Variable Contract Class shares
and Pension  Class shares will be offered at their NAV without an initial  sales
charge.
                  (b) SERVICE AND  DISTRIBUTION  FEES. In respect of the Class A
shares,  Class B shares,  Class C shares,  Variable  Contract  Class  shares and
Pension Class shares,  each Fund will pay service and/or distribution fees under
plans from time to time in effect  adopted  for such  classes  pursuant  to Rule
12b-1 under the 1940 Act (each, a "12b-1 Plan").
                  Pursuant  to a 12b-1 Plan with  respect to the Class A shares,
if effective, each Fund will generally pay (I) at the time such shares are sold,
a one-time distribution fee of







<PAGE>



up to 1% of the NAV of the  shares  sold in the  amount of $1  million  or more,
including sales  qualifying at such level under the rights of  accumulation  and
statement  of  intention  privileges,  or to  retirement  plans with 100 or more
eligible  employees,  as described in the Fund's prospectus as from time to time
in effect, (II) a continuing  distribution fee at an annual rate of 0.10% of the
average  daily NAV of the Class A share  accounts  of dealers  who meet  certain
sales and redemption  criteria,  and (III) a continuing service fee at an annual
rate not to exceed  0.25% of the  average  daily NAV of the Class A shares.  The
Board will have the  authority to increase the  distribution  fees payable under
such 12b-1 Plan by a vote of the Board,  including a majority of the independent
directors thereof, up to an annual rate of 0.25% of the average daily NAV of the
Class A shares.  The effective dates of various of the 12b-1 Plans for the Class
A shares are based on achievement by the Funds of specified total net assets for
the Class A shares of such Funds.
                
Pursuant  to a 12b-1 Plan with  respect to the Class B shares,
if effective,  each Fund will generally pay a continuing  annual fee of up to 1%
of the average annual NAV of such shares then  outstanding  (each fee comprising
 .25% in service fee and .75% in distribution fee).
                  Pursuant  to a 12b-1 Plan with  respect to the Class C shares,
if effective,  each Fund will generally pay a one-time  service and distribution
fee at the time such  shares are sold of up to 1% of their NAV and a  continuing
annual fee, commencing 12 months after the first anniversary of such sale, of up
to 1% of the  average  annual  NAV of such  shares  then  outstanding  (each fee
comprising .25% in service fees and .75% in distribution fees).
                  Pursuant to a 12b-1 plan with respect to the Variable Contract
Class,  if  operational,  the Growth & Income  Portfolio  will  generally  pay a
continuing  annual fee of up to .15% of the  average  annual NAV of such  shares
then outstanding to reimburse an insurance  company for its expenditure  related
to the distribution of such shares which  expenditures are not also reimbursable
pursuant  to fees paid  under the  variable  contract  issued by such  insurance
company.
         Pursuant  to a  12b-1  Plan  with  respect  to the  Pension  Class,  if
operational,  the Growth & Income  Portfolio  will  generally  pay a  continuing
annual fee of .45% of the average  annual NAV of such  shares then  outstanding.
The Board will have the  authority  to increase  the  distribution  fees payable
under  such  12b-1 Plan by a vote of the  Board,  including  a  majority  of the
independent  directors  thereof,  up to an annual  rate of 0.75% of the  average
daily NAV of such  shares  (consisting  of  distribution  and service  fees,  at
maximum annual rates not exceeding 0.50 and 0.25 of 1%, respectively).






<PAGE>



(c) CONTINGENT  DEFERRED  SALES CHARGES  ("CDSC").  Subject to some  exceptions,
Class A shares subject to the one-time sales  distribution fee of up to 1% under
the Rule 12b-1 Plan for the Class A shares will be subject to a CDSC equal to 1%
of the lower of the cost or the NAV of such  shares if the shares  are  redeemed
for cash on or  before  the end of the  twenty-fourth  month  after the month in
which the  shares  were  purchased.  Class B shares  will be  subject  to a CDSC
ranging from 5% to 1% of the lower of the cost or the NAV of the shares,  if the
shares are redeemed for cash before the sixth anniversary of their purchase. The
CDSC for the Class B shares  may be waived  for  certain  transactions.  Class C
shares will be subject to a CDSC equal to 1% of the lower of the cost or the NAV
of the shares if the shares are redeemed  for cash before the first  anniversary
of their  purchase.  Neither the Variable  Contract  Class nor the Pension Class
shares will be subject to a CDSC. 

 3.  CLASS-SPECIFIC  EXPENSES.  The  following
expenses  shall be  allocated,  to the extent such  expenses can  reasonably  be
identified  as  relating  to a  particular  class and  consistent  with  Revenue
Procedure  96-47,  on a  class-specific  basis:  (a)  fees  under a  12b-1  Plan
applicable  to a specific  class (net of any CDSC paid with respect to shares of
such class and






<PAGE>



retained by the Fund) and any other costs relating to  implementing  or amending
such  Plan,  including  obtaining  shareholder  approval  of  such  Plan  or any
amendment  thereto;  (b)  transfer  and  shareholder  servicing  agent  fees and
shareholder servicing costs identifiable as being attributable to the particular
provisions of a specific class; (c) sta tionery,  printing, postage and delivery
expenses  related to preparing and  distributing  materials  such as shareholder
reports,  prospectuses  and proxy  statements  to  current  share  holders  of a
specific  class;  (d)  Securities  and  Exchange  Commission  registration  fees
incurred by a specific class;  (e) Board fees or expenses  identifiable as being
attributable to a specific class;  (f) fees for outside  accountants and related
expenses relating solely to a specific class; (g) litigation  expenses and legal
fees and expense relating solely to a specific class;  (h) expenses  incurred in
connection with shareholders meetings as a result of issues relating solely to a
specific  class and (i) other  expenses  relating  solely to a  specific  class,
provided,  that advisory fees and other expenses  related to the management of a
Fund's assets (including  custodial fees and tax-return  preparation fees) shall
be  allocated  to all  shares of such Fund on the  basis of NAV,  regardless  of
whether they can be specifically  attributed to a particular  class.  All common
expenses  shall be  allocated  to shares of each class at the same time they are
allocated to







<PAGE>



the shares of all other classes. All such expenses incurred by a class of shares
will be charged directly to the net assets of the particular class and thus will
be borne on a pro rata basis by the  outstanding  shares of such class.  For all
Funds, with the exception of Series Fund - Growth & Income  Portfolio,  Blue Sky
expenses will be treated as common expenses. In the case of Series Fund - Growth
& Income Portfolio,  Blue Sky expenses will be allocated entirely to the Pension
Class, as the Variable  Contract Class of Series Fund Growth & Income  Portfolio
has no Blue Sky expenses.  4. INCOME AND EXPENSE ALLOCATIONS.  Income,  realized
and unrealized capital gains and losses and expenses not allocated to a class as
provided  above shall be  allocated to each class on the basis of the net assets
of that class in relation  to the net assets of the Fund,  except  that,  in the
case of each daily dividend Fund,  income and expenses shall be allocated on the
basis of relative net assets (settled shares).  5. DIVIDENDS AND  DISTRIBUTIONS.
Dividends and  Distributions  paid by a Fund on each class of its shares, to the
extent paid,  will be  calculated  in the same manner,  will be paid at the same
time,  and will be in the same amount,  except that the amount of the  dividends
declared  and paid by a  particular  class  may be  different  from that paid by
another class because of expenses borne exclusively by that class.







<PAGE>



6.  NET  ASSET  VALUES.  The NAV of each  share  of a class  of a Fund  shall be
determined in accordance  with the Articles of  Incorporation  or Declaration of
Trust of such Fund with  appropriate  adjustments to reflect the  allocations of
expenses,  income and realized and  unrealized  capital gains and losses of such
Fund between or among its classes as provided above. 7. CONVERSION FEATURES. The
Class B shares  will  automatically  convert to Class A shares 8 years after the
date of purchase.  Such  conversion  will occur at the relative NAV per share of
each Class without the imposition of any sales charge, fee or other charge. When
Class B shares  convert,  any other  Class B shares  that were  acquired  by the
shareholder by the reinvestment of dividends and distributions will also convert
to Class A shares on a pro rata basis. The conversion of Class B shares to Class
A shares after 8 years is subject to the  continuing  availability  of a private
letter ruling from the Internal  Revenue Service or an opinion of counsel to the
effect that the  conversion  does not constitute a taxable event for the Class B
shareholder under Federal income tax law. If such a revenue ruling or opinion is
no longer available, the automatic conversion feature may be suspended, in which
event no further conversions of Class B shares would occur while such suspension
remained in effect.  Subject to amendment by the Board, Class A shares and Class
C shares shall not be subject to any automatic conversion feature.

8. EXCHANGE PRIVILEGES.  Except as set forth in a Fund's prospectus as from time
to time in  effect,  shares of any class of such Fund may be  exchanged,  at the
holder's  option,  for shares of the same class of another  Fund,  or other Lord
Abbett-sponsored  fund or series  thereof,  without the  imposition of any sales
charge, fee or other charge.
                  Each Plan is qualified by and subject to the terms of the then
current prospectus for the applicable Fund; provided,  however, that none of the
terms  set forth in any such  prospectus  shall be  inconsistent  with the terms
contained herein. The prospectus for each Fund contains  additional  information
about that Fund's classes and its multiple-class structure.
                  Each Plan is being  adopted for a Fund with the  approval  of,
and all material amendments thereto must be approved by, a majority of the Board
of such Fund,  including a majority of the Board who are not interested  persons
of the Fund.
