Example:  Assume an  annual  return of 5% and there is no change in the level of
expenses  described above.  For a $1,000  investment,  with  reinvestment of all
distributions,  you would have paid the following  total  expenses if you closed
your account after the number of years indicated.

                         1 year          3 years

Class A shares(4)         $74             $108

Class B shares(4)         $61             $97

(1) 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 and
Class B throughout this Prospectus.

(2)See "Purchases" for descriptions of the Class A front-end sales charges,  the
CDSC payable on certain  redemptions  of Class A and Class B shares and separate
Rule  12b-1  plans  applicable  to each  class of shares  of the Fund.  The CDSC
reimburses:  (a) the  Series,  in the case of Class A shares and (b) Lord Abbett
Distributor LLC, in the case of Class B shares.

(3)Although  the Series does not,  with respect to the Class B shares,  charge a
front-end sales charge,  investors  should be aware that long-term  shareholders
may pay,  under  the Rule  12b-1  plan  applicable  to the Class B shares of the
Series (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, long-term,  such
maximum may be exceeded due to the Rule 12b-1 plan  applicable to Class A shares
which  permits  the  Series to pay up to 0.50% in total  annual  fees,  half for
service and the other half for distribution. The 12b-1 fees have been estimated.

(4)The annual  operating  expenses shown in the summary are the actual  expenses
for the period December 13, 1995  (commencement  of operations)  through May 31,
1996  (annualized)  had Lord,  Abbett & Co. not waived  its  management  fee and
subsidized  all other  expenses of the Series,  except for the  substitution  of
estimated 12b-1 fees for Class A and B shares.  Due to such waivers and subsidy,
the Series had no management fee or other expenses for such period.

The  foregoing  is provided  to give  investors  a better  understanding  of the
expenses that are incurred by an investment in the Series.

4    HOW WE INVEST

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

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

The Series  also may invest in  preferred  stocks and bonds,  which have  either
attached warrants or a conversion privilege into common stocks. In addition, the
Series may  purchase  options on stocks  that it holds as  protection  against a
significant price decline, may 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.

<PAGE>


In seeking to achieve its investment objective, the 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 largest stocks included in
the  Standard  &  Poor's  500  Composite  Index.  As  a  result,   under  normal
circumstances,  at least  65% of the  Series'  total  assets  will be made up of
common  stocks  issued  by  smaller,  less well  known  companies  (with  market
capitalizations  less than $1  billion)  selected  on the  basis of  fundamental
investment  analysis.  The Series  may,  however,  invest up to 35% of its total
assets in the  securities of any issuer without regard to its size or the market
capitalization  of its common stock.  Companies in which the 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 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  Series'  ability  to use these
strategies  may be  limited  by market  conditions,  regulatory  limits  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 Series may use these new  investments and techniques to the
extent consistent with its investment objective and policies.

OPTIONS  TRANSACTIONS.  The 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
exchange  for a  premium  paid,  the  right  for a  specified  period of time to
purchase  the  securities  subject  to the  option  at a  specified  price  (the
"exercise price" or "strike price").  The writer of a call option, in return for
the  premium,  has the  obligation,  upon  exercise of the  option,  to deliver,
depending upon the terms of the option  contract,  the underlying  securities to
the purchaser upon receipt of the exercise price.  When the Series writes a call
option,  it gives up the  potential  for gain on the  underlying  securities  in
excess of the exercise  price of the option during the period that the option is
open.

A put option on equity securities gives the purchaser,  in return for a premium,
the right, for a specified period of time, to sell the securities subject to the
option to the writer of the put at the specified  exercise price.  The writer of
the put option, in return for the premium, has the obligation,  upon exercise of
the option,  to acquire the  securities  underlying  the option at the  exercise
price. The Series as the writer of a put option might,  therefore,  be obligated
to purchase underlying securities for more that 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
prices,  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 Series will write only "covered"  options.  An option is covered if, so long
as the Series is obligated under the option,  it owns an offsetting  position in
the underlying securities or maintains cash, U.S. Government securities or other
liquid high-grade debt obligations with a value sufficient at all times to cover
its  obligations  in  a  segregated  account.  See  "Investment   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 Series may write.  The
Series  may only write  covered  put  options to the extent  that cover for such
options  does not exceed 25% of the  Series'  net  assets.  The Series  will not
purchase an option if, as a result of such purchase,  more than 20% of its total
assets would be invested in premiums for such options.

Stock Index Futures.  The Series may purchase and sell stock index futures which
are traded on a commodities  exchange or board of trade for certain  hedging and
risk  management  purposes in accordance  with  regulations  of the  Commodities
Futures Trading Commission.
A stock index  futures  contract is an  agreement  in which one party  agrees to
deliver to another an amount of cash equal to a specific dollar amount times the
difference  between a specific  stock index at the close of the last trading day
of the  contract  and the  price at which the  agreement  is made.  No  physical
delivery of the underlying stocks in the index is made.

The  Series  may not  purchase  or sell  stock  index  futures  if,  immediately
thereafter,  more than one-third of its net assets would be hedged. In addition,
except in the case of a call written and held on the same index, the Series will
write call  options on indices or sell stock  index  futures  only if the amount
resulting  from the  multiplication  of 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 Series' net assets.

<PAGE>


The  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  Series'  net  assets  (at  the  time of
investment)  may be invested in securities (of the type  described  above) which
are primarily traded in foreign countries. See "Risk Factors" below.

FOREIGN  CURRENCY  HEDGING  TECHNIQUES.  The 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 Series may enter into forward  foreign  currency
contracts in primarily  two  circumstances.  First,  when the Series  desires to
"lock in" the U.S.  dollar  price of the  security,  by entering  into a forward
contract for the purchase or sale of the amount of foreign currency  involved in
the underlying security transaction,  the Series will be able to protect against
a possible loss resulting from an adverse change in the relationship between the
U.S. dollar and the subject foreign  currency during the period between the date
of purchase or sale and the date of settlement.

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

The 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 (O-T-C
options are generally  less liquid and involve issuer credit risk). A put option
gives the Series, upon payment of a premium, the right to sell a currency at the
exercise  price until the  expiration of the option and serves to insure against
adverse currency price movements in the underlying  portfolio assets denominated
in that currency.  The premiums paid for such foreign  currency put options will
not exceed 5% of the net assets of the Series.

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

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

OTHER  POLICIES.  The 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 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 the 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.

The 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 its
assets,  may be warrants  which are not listed on the New York or American Stock
Exchanges),  but the Series has no present  intention  to commit more than 5% of
gross assets to any one of these four identified practices.  The Series will not
invest  more than 5% of its assets (at the time of  investment)  in lower  rated
(BB/Ba or lower), high-yield bonds.

The  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,  the  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.

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

<PAGE>


The Series may purchase or sell securities on a when-issued or delayed  delivery
basis.  When-issued or delayed delivery  transactions  arise when securities are
purchased or sold by the Series with  payment and delivery  taking place as much
as a month or more in the future in order to secure what is  considered to be an
advantageous  price and yield to the Series at the time of entering other liquid
high-grade debt obligations  having a value equal to or greater than the Series'
purchase commitments; the custodian will likewise segregate securities sold on a
delayed  delivery  basis.  The  securities  so  purchased  are subject to market
fluctuation and no interest  accrues to the purchaser  during the period between
purchase and settlement. At the time of delivery of the securities the value may
be more or less than the purchase price and an increase in the percentage of the
Series'  assets  committed to the purchase of  securities  on a  when-issued  or
delayed  delivery  basis may increase the  volatility  of that Series' net asset
value.

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

The  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 Series may make such a
change without shareholder approval by disclosing it in the prospectus.

RISK FACTORS.  If the 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.

FOREIGN SECURITIES.  Securities markets of foreign countries in which the Series
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  to  shareholders  and
different securities settlement  practices.  Foreign securities may be traded on
days that the Series does not value its portfolio securities,  and, accordingly,
the Series' net asset value may be significantly affected.

Under normal  circumstances,  the Series will invest primarily in common stocks,
and/or securities  convertible into common stocks,  which subjects the Series to
market risk, that is, the possibility that common stock prices will decline over
short or even extended periods.  The Series also may invest,  from time to time,
in  stocks of  large-sized  and  small-sized  companies  guided by the  policies
mentioned above. Small capitalized companies 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 these  shares  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 on a national securities exchange.

<PAGE>



Risks of Hedging and Income Enhancement Strategies. Participation in the options
or futures markets involves  investment risks and transaction costs to which the
Series  would  not be  subject  absent  the  use of  these  strategies.  If Fund
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 Fund  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.

5    PURCHASES

ALTERNATIVE SALES ARRANGEMENTS
Classes of Shares.  The Series offers investors two 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
(hereinafter  referred  to as  "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.

Which Class of Shares  Should You Choose?  Once you decide that the 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  which you should
discuss with your financial adviser. The Series' 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 the Series. We used the sales charge rates that apply
to Class A and Class B, and considered the effect of the higher distribution fee
on Class B expenses (which will affect your investment  return).  Of course, the
actual  performance of your investment  cannot be predicted and will vary, based
on the 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 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 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.  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 for
Class B  shares  from a single  investor  (i) for  $500,000  or more or (ii) for
Retirement Plans with at least 100 eligible employees.

Investing  for the Longer Term.  If you are  investing  long term (for  example,
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,  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 over time on a hypothetical investment 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 and Class B  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 withdrawals  over 12% annually).  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 shareholders will be reduced by the expenses borne
solely by this  class,  such as the  higher  distribution  fee to which  Class B
shares are subject, as described below.

<PAGE>


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.  It is  important
that investors  understand that the primary purpose of the CDSC and distribution
fee for Class B 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.

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 Series'  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.

Buying  Class A  Shares.  The  offering  price of Class A shares is based on the

</TABLE>

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 Series 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  Series 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 the 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
Class A shares  of the  Series  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 Share 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 funds,  (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.

Our Class A shares may be issued at net asset value in exchange  for the assets,
subject  to  possible  tax  adjustment,  of a  personal  holding  company  or an
investment company.

Class A Rule 12b-1 Plan.  The Fund has adopted on behalf of the Series a Class A
share Rule 12b-1 Plan (the "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 our Class A assets of up to 0.50 of 1% of the  average  net of such  assets
consisting of  distribution  and service fees, each at a maximum annual rate not
exceeding 0.25 of 1% (the "Fee Ceiling").

<PAGE>


Under the A Plan,  the Board has approved  payments by the Series 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;  (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 .10%
of the  average  daily  net  asset  value  of the  Class A  shares  serviced  by
authorized  institutions which 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 Plan, 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
will be  required to pay to the 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.  (An  exception  is 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 normally will be
deducted from the redemption proceeds. 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 CDSC is not  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).  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 Series 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.

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

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.

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 the shareholder in a non-Retirement Plan situation.

Class B Rule 12b-1 Plan.  The Fund has adopted on behalf of the Series a Class B
share Rule 12b-1 Plan (the "B Plan") under which  except as to certain  accounts
for which  tracking data is not  available)  the 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 the 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
totaling 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 Plan 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 of part of all of the
service fee payments.

<PAGE>



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.  The Series is not 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  the 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 Plan,  the 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  value 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.

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
accounts 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  either  the
current  net  asset  value of your  account  or your  original  purchase  price,
whichever is higher. For Class B shares (over 12% per year), 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); and (3) shares  held the  longest  before the
sixth anniversary of their purchase (Class B). Shareholders should be careful in
establishing  a SWP at the 12%  level,  especially  to the  extent  that  such a
withdrawal  exceeds 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 Series 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 and
custodial   agreements  for  IRAs  (Individual   Retirement  Accounts  including
Simplified  Employee  Pensions),  403(b)  plans and pension  and  profit-sharing
plans, including 401(k) 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  Small-Cap  Series of 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 65 years and  currently  manages
approximately  $19  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 P.  Fetch,  a Lord Abbett
employee  since  August  1995,  is  primarily  responsible  for  the  day-to-day
management of the Series and has been since its inception. Prior to joining Lord
Abbett,  Mr. Fetch was a Managing  Director of Prudential  Investment  Advisors.
Under the  Management  Agreement,  the Series is  obligated to pay Lord Abbett a
monthly fee based on its  average  daily net assets for each month at the annual
rate of .75%. Although this management fee was waived by

Lord Abbett for the period from December 13, 1995  (commencement  of operations)
to May 31,  1996,  the  effective  fee payable to Lord Abbett by the Series as a
percentage  of average  daily net assets is expected to be at the annual rate of
0.75% for the fiscal year following  commencement  of the offering of the Series
to the general public. In addition, we pay all expenses not expressly assumed by
Lord Abbett. The Series' ratio of expenses,  including  management fee expenses,
to  average  net assets for such six month  period is  expected  to be 1.70% and
2.20% for Class A shares and Class B shares, respectively.

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 may be paid
to shareholders quarterly in March, June, September and December.

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  distribution  will be  made  in  December  and  may be  taken  in cash or
reinvested in more shares at net asset value without a sales charge.

Supplemental dividends and distributions also may be paid in December. 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 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  pending as of the
date of this  Prospectus,  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. 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 Small-Cap Series of 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 Small-Cap Series completed its abbreviated  first half of its fiscal year on
May 31, 1996 with a net asset value of $11.98,  which was 19.80% higher than the
$10.00 net asset value at its start-up on December  13, 1995.  Net assets in the
Small-Cap Series now total more than $5.1 million.

The first five months after the Series  commenced  operations,  saw stock market
averages hover near all-time highs,  despite  weakness in the bond markets.  The
Series was heavily weighted in industrials and technology stocks; technology was
the  best  performing  sector  over  the  period.   Going  forward  the  Series'
performance will continue to be driven by individual stock selection.

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  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 Series' total return.

1    INVESTMENT OBJECTIVE

The investment  objective of the Mid-Cap Series is to seek capital  appreciation
through  investments,  primarily in equity securities,  which are believed to be
undervalued in the marketplace.

2    FEE TABLE

A summary of  expenses of the Series is set forth in the table below in order to
provide  a  better  understanding  of  such  expenses.  The  example  is  not  a
representation  of past or future expenses.  Actual expenses may be more or less
than those shown.

Shareholder  Transaction  Expenses  Mid-Cap (as a percentage of offering  price)
Series Maximum Sales Load(1) on Purchases (See  "Purchases") None Redemption Fee
None Annual Fund  Operating  Expenses  (as a  percentage  of average net assets)
Management  Fees (See "Our  Management")  .00%(2) 12b-1 Fees None Other Expenses
(See "Our Management") .00%(2) Total Operating Expenses .00%(2)

Example:  Assume annual return of the Series is 5% and there is no change in the
level of expenses described below. For a $1,000 investment, with reinvestment of
all distributions, you would pay the following total expenses if you closed your
account after the number of years indicated.

                    1 year(3)               3 years(3)

Mid-Cap Series      $0                       $0

(1)Sales "load" is referred to as sales "charge" throughout this Prospectus.

(2)Although not obligated to, Lord, Abbett & Co. intends to waive its management
fee and subsidized the expenses of the Series. The management fee for the Series
would be .75% and other  expenses are estimated to be .40% (for total  estimated
operating  expenses  of  1.15%)  for the  Series  for the full  year  after  its
commencement of operations, absent such waiver and subsidy.

(3)These  figures reflect a management fee waiver and expense subsidy from Lord,
Abbett & Co. These expenses  without such waiver and subsidy are estimated to be
$12 and $37, respectively.

4    HOW WE INVEST

The Mid-Cap  Series  invests  primarily in common stocks  (including  securities
convertible into common stocks) of mid-cap  companies,  defined for this purpose
as companies whose outstanding  equity securities have an aggregate market value
of between $200 million and $5 billion. Under normal circumstances, at least 65%
of the  Series'  total  assets  will  consist  of  investments  made in  mid-cap
companies,  determined  at the time of purchase.  Stocks are  selected  based on
capital appreciation  potential,  without regard to current income,  utilizing a
value-based, disciplined investment process that seeks to identify and invest in
undervalued securities. This investment process consists of three steps.

First,  quantitative research is used to identify a universe of stocks which are
relatively  undervalued  in comparison to other similar  investments.  From this
universe of stocks the most attractive companies are set aside as candidates for
further analysis.

In the  second  step of the  process,  fundamental  research  seeks to  identify
candidates likely to produce attractive  investment returns over a six to twelve
month time period.  This is done, for example,  by analyzing the key elements of
each company's  profitability,  such as the company's competitive position,  its
strategies  for  improving  returns  to  shareholders,  and the  probability  of
management's success based on past experience.

The  third  part of the  investment  process  is an  analysis  of the  company's
prospects  in view of our  economic  outlook for a standard  time  period.  This
outlook  is   developed   periodically   throughout   the  year,   taking   into
consideration,  for  example,  such  factors as (i) the level and  direction  of
inflation,  interest rates,  and general  economic  activity and (ii) government
monetary and fiscal policies.

The investment  portfolio of the Mid-Cap  Series will be diversified  among many
issuers  representing  many different  industries.  The portfolio of the Mid-Cap
Series  reflects the  collective  judgment of the Research  Department  of Lord,
Abbett & Co.  ("Lord  Abbett")  as to what  securities  represent  the  greatest
long-term  investment value pursuant to the Mid-Cap Series' investment objective
and  policies.  At the time of  purchase,  securities  selected  for the Mid-Cap
Series'  portfolio may be largely  neglected by the investment  community or, if
widely followed, they may be out of favor.

Mid-Cap Series may deal in options on securities,  and securities  indexes,  and
financial futures transactions,  including options on financial futures. Mid-Cap
Series may write  (sell)  covered  call options and secured put and call options
provided that no more than 5% of its net assets (at the time of purchase) may be
invested in premiums on such options.

Mid-Cap  Series is not  currently  employing  any of the options  and  financial
futures transactions described above.

OTHER POLICIES.

Foreign  Investments.  Up to 35% of the  Series'  net  assets  (at  the  time of
investment)  may be invested in securities (of the type  described  above) which
are primarily traded in foreign countries. See "Risk Factors" below.

Foreign  Currency  Hedging  Techniques.  The 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 Series may enter into forward  foreign  currency
contracts in primarily  two  circumstances.  First,  when the Series  desires to
"lock in" the U.S.  dollar  price of the  security,  by entering  into a forward
contract for the purchase or sale of the amount of foreign currency  involved in
the underlying security transaction,  the Series will be able to protect against
a possible loss resulting from an adverse change in the relationship between the
U.S. dollar and the subject foreign  currency during the period between the date
of purchase or sale and the date of settlement.

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


<PAGE>


The 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 (O-T-C
options are generally  less liquid and involve issuer credit risk). A put option
gives the Series, upon payment of a premium, the right to sell a currency at the
exercise  price until the  expiration of the option and serves to insure against
adverse currency price movements in the underlying  portfolio assets denominated
in that currency.  The premiums paid for such foreign  currency put options will
not exceed 5% of the net assets of the Series.

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

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

The  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 will not be subject to this limit.  Investments by
the Series in Rule 144A securities  initially determined to be liquid could have
the effect of diminishing the level of the 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.

The 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 its
assets,  may be warrants  which are not listed on the New York or American Stock
Exchanges),  but the Series has the present  intention to commit more than 5% of
gross  assets to any one of these four  identified  practices.  The Series  will
invest  more than 5% of its assets (at the time of  investment)  in lower  rated
(BB/Ba or lower), high-yield bonds.

The  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,  the  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.

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

The Series may purchase or sell securities on a when-issued or delayed  delivery
basis.  When-issued or delayed delivery  transactions  arise when securities are
purchased or sold by the Series with  payment and delivery  taking place as much
as a month or more in the future in order to secure what is  considered to be an
advantageous  price and yield to the Series at the time of entering other liquid
high-grade debt obligations  having a value equal to or greater than the Series'
purchase commitments; the Custodian will likewise segregate securities sold on a
delayed  delivery  basis.  The  securities  so  purchased  are subject to market
fluctuation and no interest  accrues to the purchaser  during the period between
purchase and settlement. At the time of delivery of the securities the value may
be more or less than the purchase price and an increase in the percentage of the
Series'  assets  committed to the purchase of  securities  on a  when-issued  or
delayed  delivery  basis may  increase the  volatility  of the Series' net asset
value.

The 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

<PAGE>


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 make  primarily  to defer  realization  of gain or loss for
federal tax purposes. The Series does not intend to have more than 5% of its net
assets  (determined  at the time of the  short  sale)  subject  to  short  sales
against-the-box.

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

The  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 Series may make such a
change without shareholder approval by disclosing it in the prospectus.

Risk Factors.  If the 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.

Foreign Securities.  Securities markets of foreign countries in which the Series
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  to  shareholders  and
different securities settlement  practices.  Foreign securities may be traded on
days that the Series does not value its portfolio securities,  and, accordingly,
the Series' net asset value may be significantly affected.

Under normal  circumstances,  the Series will invest primarily in common stocks,
and/or securities  convertible into common stocks,  which subjects the Series to
market risk, that is, the possibility that common stock prices will decline over
short or even extended  periods.  Although  Mid-Cap Series invests  primarily in
middle-sized  companies,  it also may  invest,  from time to time,  in stocks of
large-sized and small-sized  companies  guided by the policies  mentioned above.
Small  capitalized  companies  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 these shares 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 on a national securities exchange.

5    PURCHASES

The Series'  shares may only be  purchased  by  employees  and  partners of Lord
Abbett,  directors (trustees) of Lord Abbett-managed funds and spouses and other
family members of such employees,  partners and directors (trustees). All shares
may be purchased at the net asset value per share next computed  after the order
is received by Lord Abbett.  For the Series the minimum  initial  investment  is
$1,000.  Subsequent investments may be made in any amount. Place your order with
Lord Abbett or send it to Mid-Cap Series of the Lord Abbett  Research Fund, Inc.
(P.O. Box 419100, Kansas City, Missouri 64141).

The net asset value of the Series' shares is calculated every business day as of
the close of the New York Stock  Exchange  ("NYSE"),  by dividing  net assets by
shares  outstanding.  Securities  in the Series'  portfolio  are valued at their
market value as more fully described in the Statement of Additional Information.
A  business  day is a day on  which  the NYSE is open  for  trading.  We are not
obligated  to  maintain  the  offering  or its  terms  and the  offering  may be
suspended,  changed or withdrawn.  Lord Abbett  reserves the right to reject any
order.  Certificates  representing shares of the Series will not be issued. This
will relieve shareholders of the responsibility and inconvenience of safekeeping
share  certificates  and  save  the Fund  unnecessary  expense.  If you have any
questions, call the Fund at 800-821-5129.

Telephone Exchange Privilege: Shares may be exchanged, without a service charge,
for those of any other Lord  Abbett-sponsored  fund  except for (i) Lord  Abbett
Equity  Fund,   (ii)  Lord  Abbett  Series  Fund  and  (iii)  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 (together,  "Eligible Funds").  You or
your representative with proper identification can instruct the Fund to exchange
shares 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 (800-521-5315) 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.

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  (herein
referred to as  "management").  We employ Lord Abbett as investment  manager for
the  Series  pursuant  to a  Management  Agreement.  Lord  Abbett  has  been  an
investment  manager for over 65 years and currently  manages  approximately  $20
billion  in a family of mutual  funds and  other  advisory  accounts.  Under the
Management  Agreement,  Lord  Abbett is  obligated  to provide  the Series  with
investment  management  services  and  executive  and other  personnel,  pay the
remuneration  of our officers and of our directors  affiliated with Lord Abbett,
provide us with  office  space and pay for  ordinary  and  necessary  office and
clerical expenses relating to research,  statistical work and supervision of the
Series' 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.  John J. Walsh,  Jr.,  Lord Abbett
partner  for over  five  years,  is  primarily  responsible  for the  day-to-day
management of the

Mid-Cap  Series and has been since  inception.  Mr. Walsh  delegates  management
duties with  respect to the Mid-Cap  Series to a  committee  consisting,  at any
time, of three Lord Abbett employees from the Research  Department.  The members
of the committee,  who also may be officers of the Fund, have staggered terms to
assure  continuity  and a forum for  different  judgments as to what  securities
represent the greatest investment value for the Mid-Cap Series.

Under the  Management  Agreement,  the Series is  obligated to pay Lord Abbett a
monthly fee based on its  average  daily net assets for each month at the annual
rate of .75%.  This fee is higher than that used for most mutual funds.  Because
Lord Abbett  intends to waive the payment of the  management  fee,  for the year
after  commencement  of operations  of the Series,  the effective fee payable to
Lord  Abbett by the  Series  as a  percentage  of  average  daily net  assets is
expected to be at the annual rate of zero percent for such period.  In addition,
we pay all expenses not expressly  assumed by Lord Abbett.  The Series' ratio of
expenses,  including  management  fee  expenses,  to average net assets for such
one-year period is expected to be zero percent.

8    DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES


With respect to the Series,  dividends from taxable net investment income may be
taken in cash or invested  in  additional  shares at net asset value  (without a
sales charge) and will be paid to shareholders annually in December.

A long-term  capital gains  distribution is made when the Series has net profits
during the year from sales of  securities  which it has held more than one year.
If the Series has  realized  net  short-term  capital  gains,  they also will be
distributed.  Any capital gains distributions will be made annually in December.
They may be taken in cash or invested in more shares at net asset value  without
a sales charge.

Dividends  and  distributions  declared in October,  November or December of any
year will be treated for federal  income tax purposes as having been received by
shareholders  of the Series in that year if they are paid  before  February 1 of
the following year. A supplemental  capital gains  distribution also may be paid
in December.

The Series  intends to meet the  requirements  of  Subchapter  M of the Internal
Revenue Code. The Series will try to distribute to  shareholders  all of its net
investment  income and net realized  capital gains, so as to avoid the necessity
of 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  us  as  "capital  gains
distributions"  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 of the Series.  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  is pending in Congress as of the date of this  Prospectus,
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 or repurchase proceeds 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.
Limitations  imposed  by the  Internal  Revenue  Code  on  regulated  investment
companies may restrict the Series' ability to engage in transactions in options,
forward contracts and cross hedges.

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 on 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.  This
privilege is automatically  extended to all  shareholders.  The Fund will not be
liable for following  instructions  communicated by telephone that it reasonably
believes  to be genuine  with  respect to the Fund and,  therefore,  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 cannot use the expedited redemption  procedures described above to redeem
shares directly, send your request to Mid-Cap Series of 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.

Under certain  circumstances  and subject to 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.

10   PERFORMANCE

Lord  Abbett  Research  Fund - Mid-Cap  Series  completed  the first half of its
fiscal  year on May 31,  1996.  The Series' net asset value was $11.16 per share
versus  $10.16 six months age (the  latter  figure has been  adjusted to reflect
distributions  totalling $.02 paid to shareholders  on December 29, 1995).  Over
the period the Series produced a total return of 11.1%.

During the period the Series  was  essentially  sector-neutral  relative  to the
unmanaged S&P 500's weightings with two exceptions:  the Series was overweighted
in financial stocks (mainly banks and insurance companies) and consumer cyclical
stocks  (which  tend to rise when the  economy  is  expanding  and fall when the
economy slows down).

Total Return.  We calculate our average annual total return for the Series for a
given  period by  determining  an annual  compounded  rate that would  cause the
hypothetical initial investment made on the first day of the period to equal the
ending  redeemable  value.  The  calculation  assumes  for the  period  a $1,000
hypothetical  initial  investment in the Series,  the reinvestment of all income
and  capital  gains  distributions  on the  reinvestment  dates  at  the  prices
calculated as stated in the Prospectus,  and a complete redemption at the end of
the period to determine the ending redeemable value.  Further  information about
the Series'  performance will be in its annual report to shareholders  which may
be obtained without charge.

STATEMENT OF ADDITIONAL INFORMATION                            OCTOBER 31, 1996


                         LORD ABBETT RESEARCH FUND, INC.
                                SMALL-CAP SERIES

This Statement of Additional  Information is not a Prospectus.  A Prospectus 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 October 31, 1996.

Small-Cap Series (the "Series" or "we") is a diversified separate series of Lord
Abbett  Research  Fund,  Inc.  (sometimes  referred to as the "Fund")  which was
incorporated  under  Maryland law on April 6, 1992. As of October 30, 1996,  our
50,000,000 shares of authorized  capital stock consist of two classes (A and B),
$0.001 par value. The Board of Directors will allocate these  authorized  shares
of capital stock among the classes from time to time. Prior to October 30, 1996,
we had only one class of  shares,  which  class is now  designated  Class A. The
Class A and B shares will be offered to the general public for the first time on
or about  November 15, 1996. 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.

Rule 18f-2  under the  Investment  Company Act of 1940,  as amended  (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  affected by such matter.  Rule 18f-2  further
provides  that a class  shall be deemed to be  affected  by a matter  unless the
interests of each class in the matter are substantially  identical or the matter
does not affect any  interest  of such  class.  However,  the Rule  exempts  the
selection  of  independent  public   accountants,   the  approval  of  principal
distributing  contracts and the election of directors  from its separate  voting
requirements.

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 LLC.

                               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.  The
Series may not:  (1) borrow  money,  except  that (i) the 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) the  Series  may  borrow up to an  additional  5% of its total  assets  for
temporary purposes, (iii) the Series may obtain such short-term credit as may be
necessary for the clearance of purchases and sales of portfolio  securities  and
(iv) the 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 the 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  the  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 the 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 the  Series,  buy
securities  of one issuer  representing  more than (i) 5% of the  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.  The 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 the 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 the Series' total assets (included within such limitation,  but not to exceed
2% of the 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 the 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 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 Series' common stock.

For the period from December 13, 1995  (commencement  of  operations) to May 31,
1996, the portfolio turnover rate was 23.33%.

LENDING OF PORTFOLIO SECURITIES.  Although we have no current intention of doing
so in the foreseeable  future,  we 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.  We 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 the
Series' gross assets.

REPURCHASE  AGREEMENTS.  If the Series  enters  into  repurchase  agreements  as
provided in clause (4) 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 Series
otherwise may invest.

OTHER  INVESTMENT   RESTRICTIONS  (WHICH  CAN  BE  CHANGED  WITHOUT  SHAREHOLDER
APPROVAL)

FOREIGN  CURRENCY  HEDGING  TECHNIQUES.  The 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 Series  expects to enter into  forward  foreign
currency contracts in primarily two circumstances. First, when the Series enters
into a contract for the purchase or sale of a security  denominated in a foreign
currency,  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 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 Series may enter into
a forward  contract  to sell the amount of foreign  currency  approximating  the
value of some or all of the Series'  portfolio  securities  denominated  in such
foreign  currency  or, in the  alternative,  the Series may use a  cross-hedging
technique  whereby it sells another currency which the 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 Series  does not  intend to enter  into such  forward
contracts under this second circumstance on a continuous basis.

FOREIGN  CURRENCY PUT AND CALL  OPTIONS.  The 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 Series, upon payment of
a  premium,  the  right to sell a  currency  at the  exercise  price  until  the
expiration of the option and serves to insure  against  adverse  currency  price
movements in the underlying portfolio assets denominated in that currency.

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

A call  option  written by the Series  gives the  purchaser,  upon  payment of a
premium,  the right to purchase from the Series a currency at the exercise price
until the  expiration  of the  option.  The Series may write a call  option on a
foreign currency

                                                         3

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 Series or in such  cross  currency  (referred  to above) to cover such
call writing.

The Fund's  custodian will segregate cash or liquid  high-grade  debt securities
belonging to the Series in an amount not less than that  required by SEC Release
10666 with respect to the Series' assets committed to (a) writing  options,  (b)
forward  foreign  currency  contracts  and (c) cross hedges  entered into by the
Series. If the value of the securities  segregated declines,  additional cash or
debt securities will be added on a daily basis (i.e., marked to market), so that
the  segregated  amount  will  not be  less  than  the  amount  of  the  Series'
commitments  with  respect to such written  options,  forward  foreign  currency
contracts and cross hedges.

LIMITATIONS ON THE SERIES' PURCHASE AND SALE OF STOCK OPTIONS,  OPTIONS ON STOCK
INDICES AND STOCK INDEX FUTURES

The Series may write put and call  options on stocks  only if they are  covered,
and such  options  must remain  covered so long as the Series is  obligated as a
writer.  The 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 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
Series' total net assets.

SERIES' CALL  OPTIONS ON STOCK.  The Series may,  from time to time,  write call
options on its  portfolio  securities.  The  Series may write only call  options
which are "covered," meaning that the 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 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 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  Series  by the
purchaser of the option is the "premium." The 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 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 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 Series is
required to comply with the rules of The Options  Clearing  Corporation  and the
various  exchanges with respect to collateral  requirements.  The 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 Series for writing the option.

Generally,  the 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 Series'  net asset value  occasioned  by such  declines in market  value.
Except  as part of the  "sell  discipline"  described  below,  the  Series  will
generally  not write listed  covered call options when it  anticipates  that the
market values of the Series' portfolio securities will increase.

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


                                                         4

<PAGE>



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
Series,  the market price of a stock is  overvalued  and it should be sold,  the
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 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 Series would,  in effect,  have increased the selling price of the
stock.  The 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.

SERIES' PUT OPTIONS ON STOCK.  The Series may also write listed put options.  If
the 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
Series has cash or other reserves  available for investment as a result of sales
of 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 Series 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 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 Series for
the  stock.  The price of the stock  may  decline  by an amount in excess of the
premium,  in which  event the  Series  would have  foregone  an  opportunity  to
purchase the stock at a lower price.

If,  prior to the  exercise of a put option,  the 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.

At the time a put option is written,  the Series will be required to  establish,
and will  maintain  until the put is  exercised  or has  expired,  a  segregated
account  with its  custodian  consisting  of cash,  short-term  U.S.  Government
securities or other high-grade short-term debt obligations equal in value to the
amount the Series will be obligated to pay upon exercise of the put option.

SERIES' STOCK INDEX  OPTIONS.  Except as describe  below,  the 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 Series writes a call option on a broadly-based stock market
index,  the 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 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.  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 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
Series will so segregate,  escrow or pledge an amount in cash, Treasury bills or
other high-grade  short-term  obligations  equal in value to the difference.  In
addition, when the Series writes a call on an index which is in-the-money at the
time the call is written, the Series will segregate with its custodian or pledge
to the broker as collateral cash, 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
Series' obligation to segregate  additional amounts in the event that the market
value of the

                                                         5

<PAGE>



qualified  securities  falls  below 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  Series  has not  written a stock  call  option and which has not been
hedged by the Series by the sale of stock index futures.  However, if the 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 Series in cash, 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.

SERIES' STOCK INDEX  FUTURES.  The 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 Series'  portfolio
or which it intends to  purchase.  The Series will  engage in such  transactions
when they are  economically  appropriate  for the reduction of risks inherent in
the ongoing  management of the Series. The 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 Series' net assets.

SEGREGATED/MARGIN  ACCOUNT.  In instances  involving the purchase of stock index
futures contracts by the Series, an mount of cash or permitted  securities equal
to the market value of the futures  contracts  will be deposited in a segregated
account with the Series'  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 Series' commodity futures or commodity options  transactions
constitute  bona fide  hedging  transactions  within  the  meaning of the CFTC's
regulations.  The Series will use stock index  futures and options on futures as
described herein in a manner consistent with this requirement.

SERIES' RISKS OF  TRANSACTIONS IN STOCK OPTIONS.  Writing  options  involves the
risk that there will be no market in which to effect a closing  transaction.  An
option position may be closed out only on an exchange which provides a secondary
market for an option of the same  series.  Although  the 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 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.

SERIES' RISKS OF OPTIONS ON INDICES. The Series' purchase and sale of options on
indices  will be  subject  to  risks  described  above  under  "Series'  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 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 Series of options on indices would be
subject to the investment  adviser's ability to predict  correctly  movements in
the direction of the stock market  generally or of a particular  industry.  This
requires different skills and techniques than predicting changes in the price of
individual stocks.

Index prices may be distorted if trading of certain stocks included in the index
is  interrupted.  Trading in the index option also may be interrupted in certain
circumstances,  such as if trading were halted in a substantial number of stocks
included in the index.  If this occurred,  the 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

                                                         6

<PAGE>



to the Series.  It is the 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 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.

SERIES'  SPECIAL RISKS OF WRITING CALLS ON INDICES.  Because  exercises of index
options are settled in cash, a call writer such as the Series  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  Series  will  write  call  options  on  indices  only  under  the
circumstances  described above under  "Limitations  on the Series'  Purchase and
Sale of Stock Options, Options on Stock Indices and Stock Index Futures."

Price movements in the 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 by the Series may not  increase  as
much as the index.  In such event the Series would bear a loss on the call which
is not completely offset by movements in the price of the Series' portfolio.  It
is also  possible  that the index may rise when the Series'  portfolio of stocks
does not rise. If this occurred,  the 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 Series in the  opposite  direction  as the market
would be likely to occur for only a short period or to a small degree.

Unless the Series has other liquid  assets which are  sufficient  to satisfy the
exercise  of a call,  the  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 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  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 Series is able to
sell stocks in its portfolio.  As with stock options,  the 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 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 Series has written is "covered" by an index call
held by the Series  with the same  strike  price,  the 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  Series  exercises  the call it holds or the time the
Series  sells the call which in either case would occur no earlier  than the day
following the day the exercise notice was filed.

SERIES'  SPECIAL  RISKS OF PURCHASING  PUTS AND CALLS ON INDICES.  If the 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 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.

    August  1,  1995,  no  compensation  was paid to  directors  of the  Series.
    Commencing  on November 15,  1996,  the Series will accrue for its shares of
    compensation for each outside director.

2.   Each other Lord  Abbett-sponsored fund (not the Fund) has a retirement plan
     providing that outside  directors will receive annual  retirement  benefits
     for life equal to 80% 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.  The amounts stated would be payable
     annually under such retirement  plans if the director were to retire at age
     72 and the annual retainers payable by such funds were the same as they are
     today.  The  amounts  accrued  in column 3 were  accrued  by the other Lord
     Abbett-sponsored funds (not the Fund) during the fiscal year ended November
     30, 1995 with respect to the retirement benefits in column 4.

3.  This column shows  aggregate  compensation,  including  director's  fees and
    attendance fees for board and committee meetings, of a nature referred to in
    footnote  two,  accrued  by the other Lord  Abbett-sponsored  funds (not the
    Fund) during the year ended December 31, 1995.

4.   Messrs. Bigelow, Dixon, Jansing and MacDonald were elected directors of the
     Fund subsequent to the end of the last fiscal year.

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 May 31, 1996 our officers and  directors as a group owned less than 52% 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  Foster,  Robert G.
Morris,  Robert 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 the  Series'  average  daily net assets.  During the
period from December 13, 1995  (commencement of operations) to May 31, 1996 Lord
Abbett waived a management fee of $8,165 and assumed expenses of $3,855.

We are  obligated  to pay all  expenses  not  expressly  assumed by Lord Abbett,
including, without limitation, outside directors' fees and expenses, 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.

Deloitte & Touche LLP, Two World Financial Center,  New York, New York 10281 are
the  independent  auditors 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.


                                                        10

<PAGE>



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 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 period beginning  December 13, 1995  (commencement of operations)
to May 31, 1996, we paid total  commissions  to  independent  broker-dealers  of
$13,218.

                             Purchases, Redemptions
                            and Shareholder Services

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

As disclosed in the Prospectus, we calculate our net asset value as of the close
of the New York Stock  Exchange  ("NYSE")  on each day that the NYSE is open for
trading by dividing our total net assets by the number of shares  outstanding at
the time of  calculation.  The NYSE is closed on  Saturdays  and Sundays and the
following  holidays -- New Year's Day,  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 shares will be  determined  in the
same  manner  as  for  the  Class  A  shares  (net  assets   divided  by  shares
outstanding). Our Class B shares will be sold at net asset value.

The maximum offering price of our Class A shares on May 31, 1996 was computed as
follows:

                                                                     CLASS A
Net asset value per share (net assets divided
by shares outstanding)..............................................$11.98

Maximum offering price per share (net asset
value divided by .9425).............................................$12.71

Our Class B 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.

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 AND B RULE 12B-1 PLANS.  As described  in the  Prospectus,  the Fund has
adopted a Distribution Plan and Agreement  pursuant to Rule 12b-1 of the Act for
each of the two series classes: the "A Plan" and the "B Plan", 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

                                                        12

<PAGE>



to shareholders by authorized institutions than would otherwise be the case. The
Plans were adopted by the Fund subsequent to its last fiscal year.

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 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 Order Was Accepted          on Redemptions (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.


                                                        13

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

With respect to Class A and Class B shares, no CDSC is payable on redemptions by
participants in or  beneficiaries of  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.
In the case of  Class A  shares,  the  CDSC is  received  by the  Series  and is
intended  to  reimburse  all or a portion of the amount  paid by the Fund if the
shares are  redeemed  before the Series has had an  opportunity  to realize  the
anticipated benefits of having a long-term shareholder account in the Series. 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  Series  (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
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 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).  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 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

                                                        14

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 the Fund's  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 the Fund not
offered to the general public ("LARF").

STATEMENT OF INTENTION.  Under the terms of the Statement of Intention to invest
$100,000  or more over a 13-month  period as  described  in the  Prospectus,  in
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) shares  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 the  Fund's  directors,
employees of Lord Abbett,  employees of the Fund's  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 director's or employee's  spouse  (including the surviving spouse of a
deceased director or employee).  The terms "the Fund's directors" and "employees
of Lord Abbett" also include  retired  directors  and employees and other family
members thereof.

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 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,

                                                        15

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,  and (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.  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.

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 at any time.

Our Class A shares may be issued at net asset value in exchange  for the assets,
subject  to  possible  tax  adjustment,  of a  personal  holding  company  or an
investment  company.  There are economies of selling  efforts and  sales-related
expenses with respect to offers to these investors and those referred to above.

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 on redemptions of up to 12% per
year of either the  current  net asset  value of your  account or your  original
purchase price,  whichever is higher. The SWP involves the planned redemption of
shares on a periodic  basis by  receiving  either  fixed or variable  amounts 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

                                                        16

<PAGE>



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  and  custodial  agreements  for  IRAs  (Individual
Retirement Accounts,  including Simplified Employee Pensions),  403(b) plans and
qualified pension and  profit-sharing  plans,  including 401(k) 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.

                                Past Performance

The 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).  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.  Prior
to July 12,  1996,  the Fund had only one class of  shares,  which  class is now
designated Class A.

Using the method to compute  average annual  compounded  total return  described
above,  for the  life-of-series  period  (from  commencement  of  operations  on
December  13, 1995  through May 31, 1996)  assuming a $1,000  investment  at the
beginning of the period,  the average annual rate of total return of the Class A
shares of the Series  amounted to 19.80%  (not  annualized)  and the  redeemable
value was $1,198.

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 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
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.

                                      Taxes

The value of any shares  redeemed by the 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 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.

The 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.  The 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
the 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 the Series.  Such transactions may increase the amount of short-term  capital
gain realized by the Series,  which is taxed as ordinary income when distributed
to shareholders.  Limitations  imposed by the Internal Revenue Code on regulated
investment  companies may restrict the Series' ability to engage in transactions
in options. As described in the Prospectus under "How We Invest - Risk Factors,"
the 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  Series
shareholders  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 the Series.

Gains and losses realized by the 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.

If the 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 the  Series  were to invest  in a passive  foreign  investment  company  with
respect  to  which  the  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 the Series.

Gains or losses on sales of securities  by the Series will be long-term  capital
gains or losses if the  securities  have been held by it for more than one year,
except in certain cases where the Series acquires a put or writes a call thereon
or otherwise holds an offsetting position with respect to the securities.  Other
gains or losses on the sale of securities  will be  short-term  capital gains or
losses.  If an option  written by the Series lapses or is  terminated  through a
closing  transaction,  such as a repurchase by the Series of the option from its
holder, the Series will realize a short-term capital gain or loss,  depending on
whether the premium income is greater or less than the amount paid by the Series
in the closing transaction. If securities are sold by the Series pursuant to the
exercise  of a call  option  written  by it,  the  Series  will add the  premium
received to the sale price of the securities delivered in determining the amount
of gain or loss on the sale. If securities are purchased by the Series  pursuant
to the  exercise  of a put option  written by it, the Series will  subtract  the
premium received from its cost basis

                                                        18

<PAGE>


in the securities  purchased.  The requirement  that the Series derive less than
30% of its gross  income  from gains from the sale of  securities  held for less
than three months may limit the Series' ability to write options.

Certain futures  contracts and certain listed options held by the 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).  60% 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.

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

                           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.

LORD ABBETT
STATEMENT OF ADDITIONAL INFORMATION                         OCTOBER 31, 1996


                         LORD ABBETT RESEARCH FUND, INC.
                                 MID-CAP SERIES
- ------------------------------------------------------------------------------


This Statement of Additional  Information is not a Prospectus.  A Prospectus may
be  obtained  from your  securities  dealer or from  Lord,  Abbett & Co.  ("Lord
Abbett") 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 October 31, 1996.

Lord  Abbett  Research  Fund,  Inc.  (sometimes  referred  to as the "Fund") was
incorporated  under Maryland law on April 6, 1992. The Fund's Board of Directors
has  authority  to  classify  its shares of common  stock into  separate  Series
without further action by  shareholders.  The Fund has three Series:  Large-Cap,
Mid-Cap  and  Small-Cap.  Only  Mid-Cap  Series  (sometimes  referred  to as the
"Series" or "we" and/or  "Mid-Cap  Series") is  described  in this  Statement of
Additional  Information.  To date, 50,000,000 shares of Mid-Cap Series have been
designated by the Board of Directors.  Although no present plans exist,  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, the series
must be  preferred  over all other  series with  respect to 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 the series affected by such
matter. Rule 18f-2 further provides that a Series shall be deemed to be affected
by a matter  unless the  interests of the series in the matter are  identical or
the matter  does not affect  any  interest  of such  Series.  However,  the Rule
exempts from these  separate  voting  requirements  the selection of independent
public  accountants,  the approval of principal  distributing  contracts and the
election of directors.

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.

                        Investment Objective and Policies

FUNDAMENTAL  INVESTMENT  RESTRICTIONS.  The  Series'  investment  objective  and
policies are described in the Prospectus  under "How We Invest".  In addition to
those  policies  described  in the  Prospectus,  the  Series is  subject  to the
following  fundamental  investment  restrictions which cannot be changed for the
series  without  the  approval  of the  holders  of a  majority  of the  Series'
respective  shares.  The Series may not: (1) borrow  money  (except that (i) the
series may borrow from banks (as defined in the Act) in amounts up to 33 1/3% of
its total assets (including the amount borrowed),  (ii) the Series may borrow up
to an additional 5% of its total assets for temporary purposes, (iii) the series
may obtain such  short-term  credit as may be  necessary  for the  clearance  of
purchases  and sales of  portfolio  securities  and (iv) the Series may purchase
securities on margin to the extent  permitted by applicable law); (2) pledge its
assets (other than to secure such borrowings or, to the extent  permitted by the
Series'  investment  policies as set forth in its  prospectus  and  statement of
additional information,  as they may be amended from time to time, in connection
with hedging  transactions,  short  sales,  when-issued  and forward  commitment
transactions and similar investment strategies);  (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 deemed to be the
making of a loan,  and except  further  that the  Series may lend its  portfolio
securities,  provided that the lending of portfolio  securities may be made only
in accordance  with  applicable  law and the guidelines set forth in the series'
prospectus and statement of additional information,  as they may be amended from
time to time;  (5) buy or sell real estate (except that the 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),
commodities or commodity contracts (except to the extent the 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 the  Series,  buy
securities  if the purchase  would then cause it to (i) have more than 5% of its
gross  assets,  at  market  value at the  time of  investment,  invested  in the
securities of any one issuer except  securities issued or guaranteed by the U.S.
Government,  its agencies or  instrumentalities or (ii) own more than 10% of the
voting securities of any 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 change 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 those policies described
in the Prospectus and the investment  restrictions above which cannot be changed
without shareholder  approval,  the Series also is subject to the following non-
fundamental  investment  policies which may be changed by the Board of Directors
without shareholder  approval.  The Series may not: (1)borrow in excess of 5% of
make short sales of securities or maintain a short position except to the extent
permitted  by  applicable  law;  (2) invest  knowingly  more than 15% of its net
assets (at the time of investment) in illiquid securities (securities qualifying
for resale under Rule 144A of the  Securities Act of 1933 ("Rule 144A") that are
determined by the Directors,  or by Lord Abbett pursuant to delegated authority,
to be liquid are considered liquid securities);  (3) invest in securities issued
by other investment  companies as defined in the Act, except as permitted by the
Act; (4) purchase  securities of any issuer unless it or its  predecessor  has a
record of three years' continuous operation, except that the Series may purchase
securities  of such  issuers  through  subscription  offers  or other  rights it
receives  as a security  holder of  companies  offering  such  subscriptions  or
rights,  and such  purchases  will then be limited in the aggregate to 5% of the
Series' net assets at the time of investment;  (5) hold securities of any issuer
when more than 1/2 of 1% of the issuer's  securities are owned  beneficially  by
one or more of the Fund's  officers or directors  or by one or more  partners of
the Fund's  underwriter  or investment  adviser if these owners in the aggregate
own beneficially more than 5% of such securities; (6) invest in warrants, valued
at the  lower  of cost or  market,  to  exceed  5% of the  Series'  net  assets,
including  warrants not listed on the New York or American  Stock Exchange which
may not  exceed 2% of such net  assets;  or (7)  invest in real  estate  limited
partnership  interests  or  interest in oil,  gas or other  mineral  leases,  or
exploration  or  development  programs,  except  that the  Series  may invest in
securities  issued  by  companies  that  engage  in oil,  gas or  other  mineral
exploration or development activities.

INVESTMENT TECHNIQUES WHICH MAY BE USED BY THE SERIES

LENDING OF PORTFOLIO SECURITIES. Although the Series has no current intention of
doing so in the  foreseeable  future,  the  Series  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. The 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 the Series will receive the income earned on investment
of collateral.  The aggregate value of the securities  loaned will not exceed 5%
of the value of the Series' gross assets.

If the Series enters into repurchase agreements as provided in clause (4) 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 Series otherwise may invest.

FOREIGN  CURRENCY  HEDGING  TECHNIQUES.  The 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 Series  expects to enter into  forward  foreign
currency contracts in primarily two circumstances. First, when the Series enters
into a contract for the purchase or sale of a security  denominated in a foreign
currency,  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 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 Series may enter into
a forward  contract  to sell the amount of foreign  currency  approximating  the
value of some or all of the Series'  portfolio  securities  denominated  in such
foreign  currency  or, in the  alternative,  the Series may use a  cross-hedging
technique  whereby it sells another currency which the 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 Series  does not  intend to enter  into such  forward
contracts under this second circumstance on a continuous basis.

FOREIGN  CURRENCY PUT AND CALL  OPTIONS.  The 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 Series, upon payment of
a  premium,  the  right to sell a  currency  at the  exercise  price  until  the
expiration of the option and serves to insure  against  adverse  currency  price
movements in the underlying portfolio assets denominated in that currency.

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

A call  option  written by the Series  gives the  purchaser,  upon  payment of a
premium,  the right to purchase from the Series a currency at the exercise price
until the  expiration  of the  option.  The Series may write a call  option on a
foreign  currency  only in  conjunction  with a purchase of a put option on that
currency.  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 a Series or in such cross currency (referred

                                                         3

to above) to cover such call writing.

The Fund's  custodian will segregate cash or permitted  securities  belonging to
the Series in an amount not less than that  required  by SEC  Release  10666 and
related  policies  with respect to the Series'  assets  committed to (a) writing
options,  (b) forward  foreign  currency  contracts and (c) cross hedges entered
into  by  the  Series.  If the  value  of the  securities  segregated  declines,
additional cash or debt securities will be added on a daily basis (i.e.,  marked
to market),  so that the  segregated  amount will not be less than the amount of
the Series'  commitments with respect to such written  options,  forward foreign
currency contracts and cross hedges.

1.  Prior to the  offering  of shares of the  Series  to the  general  public on
    August  1,  1995,  no  compensation  was paid to  directors  of the  Series.
    Commencing  on November 15,  1996,  the Series will accrue for its shares of
    compensation for each outside director.

2.   Each other Lord  Abbett-sponsored fund (not the Fund) has a retirement plan
     providing that outside  directors will receive annual  retirement  benefits
     for life equal to 80% 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.  The amounts stated would be payable
     annually under such retirement  plans if the director were to retire at age
     72 and the annual retainers payable by such funds were the same as they are
     today.  The  amounts  accrued  in column 3 were  accrued  by the other Lord
     Abbett-sponsored funds (not the Fund) during the fiscal year ended November
     30, 1995 with respect to the retirement benefits in column 4.

3.  This column shows  aggregate  compensation,  including  director's  fees and
    attendance fees for board and committee meetings, of a nature referred to in
    footnote  two,  accrued  by the other Lord  Abbett-sponsored  funds (not the
    Fund) during the year ended December 31, 1995.

4.   Messrs. Bigelow, Dixon, Jansing and MacDonald were elected directors of the
     Fund subsequent to the end of the last fiscal year.

                     Investment Advisory and Other Services

As described under "Our Management" in the Prospectus, Lord Abbett is the Fund's
investment  manager.  The eight general partners of Lord Abbett, all of whom are
officers and/or directors of the Fund, are: Stephen I. Allen,  Daniel E. Carper,
Kenneth B. Cutler,  Robert S. Dow,  Thomas S.  Henderson,  Robert G. Morris,  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 the Series' average daily net assets. For the period
from August 1, 1995 (commencement of operations)  through November 30, 1995, and
the six months ended May 31, 1996 this  management fee was waived by Lord Abbett
with  respect to the Mid-Cap  Series  and,  except for this  waiver,  would have
amounted to $2,125 and $3,905, respectively.

We are  obligated  to pay all  expenses  not  expressly  assumed by Lord Abbett,
including,  without  limitation,  12b-1  expenses,  outside  directors' fees and
expenses,  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 the Series'
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
period from August 1, 1995  (commencement  of operations)  through  November 30,
1995 and the six months ended May 31, 1996, Lord Abbett,  although not obligated
to, voluntarily assumed the  above-mentioned  expenses which, if not so assumed,
would have  amounted to $7,544 and  $9,000,  respectively,  with  respect to the
Mid-Cap Series.

Deloitte & Touche LLP, Two World Financial Center,  New York, New York 10281 are
the  independent  auditors of the Fund and must be approved at least annually by
our 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 ("BONY"), 48 Wall Street, New York, New York, 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 BONY 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.

                                                         6

<PAGE>



Consistent with obtaining best execution, we pay a commission rate determined to
attract the services we require,  as described below. That rate may be higher or
lower than other 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 in a timely manner, including blocks, a willingness and
ability to take positions in securities,  knowledge of a particular  security or
market  proven  ability  to  handle a  particular  type of  trade,  confidential
treatment, promptness and reliability.

Some of these brokers also provide research  services at least some of which are
useful to Lord Abbett in their overall  responsibilities  with respect to us and
the other accounts they manage. Research includes the furnishing of analyses and
reports concerning issuers, industries, securities, economic factors and trends,
portfolio  strategy and the  performance  of accounts and trading  equipment and
computer software  packages,  acquired from third-party  suppliers,  that enable
Lord Abbett to access various  information  bases.  Such services may be used by
Lord Abbett in servicing all their  accounts,  and not all of such services will
necessarily  be used by Lord Abbett in connection  with their  management of the
Fund; conversely,  such services furnished in connection with brokerage on other
accounts  managed by Lord Abbett may be used in connection with their management
of the  Fund,  and not all of such  services  will  necessarily  be used by Lord
Abbett in connection  with their advisory  services to such other  accounts.  We
have been advised by Lord Abbett that  research  services  received from 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 therm of
portfolio business.

If we tender portfolio  securities pursuant to a cash tender offer, we will seek
to recapture any fees or  commissions  involved by  designating  Lord Abbett our
agent so that the fees may be passed  back to us. As other  legally  permissible
opportunities  come to our attention for the direct or indirect  recapture by us
of brokerage  commissions  or similar fees paid on portfolio  transactions,  our
directors will determine whether we should or should not seek such recapture.

For the period from August 1, 1995 (commencement of operations) through November
30, 1995 and the six months ended May 31,  1996,  we paid total  commissions  to
independent broker-dealers of $3,245 and $834, respectively, with respect
to the Mid-Cap Series.

                             Purchases, Redemptions
                            and Shareholder Services

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

As disclosed in the Prospectus, we calculate our net asset value as of the close
of the New York Stock  Exchange  ("NYSE")  on each day that the NYSE is open for
trading by dividing our total net assets by the number of shares  outstanding at
the time of  calculation.  The NYSE is closed on  Saturdays  and Sundays and the
following  holidays -- New Year's Day,  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 maximum offering price of our shares on May 31, 1996 was computed as follows
(assuming no sales charge currently in effect):

                                                                 MID-CAP SERIES

Maximum offering price per share is equal to
the net asset value per share
(net assets divided by shares outstanding)........................$11.16

The Fund has entered into a distribution  agreement with Lord Abbett under which
Lord Abbett is  obligated  to use its best  efforts to find  purchasers  for the
shares of the Fund and to make reasonable  efforts to sell the Series' shares so
long as, in Lord Abbett's judgment,  a substantial  distribution can be obtained
by reasonable efforts.

As stated in the Prospectus, our shares may be purchased at net asset value only
by  directors  (trustees)  of the Lord  Abbett-  sponsored  funds,  partners and
employees of Lord Abbett, and spouses and other family members of such directors
(trustees), partners and employees.

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.

                                                         8

<PAGE>



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 60 days' 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.

                                       6.
                                Past Performance

The Fund  computes the average  annual  compounded  rate of total return  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 (in this case there
is no sales charge) 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.

These figures represent past  performance,  and an investor should be aware that
the investment return and principal value of a Fund 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 the Fund or  otherwise  sold may be more or
less  than your tax basis in the  shares at the time the  redemption  or sale is
made.  Any  gain or loss  generally  will be  taxable  for  federal  income  tax
purposes. Any loss realized on the sale or redemption of 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 sale, the taxpayer acquires stock or securities
that are substantially identical.

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

As described in the  Prospectus  under "How We Invest - Risk  Factors," the Fund
may be subject to foreign  withholding taxes which would reduce the yield on its
investments.  Tax treaties  between certain  countries and the United States may
reduce or eliminate such taxes. It is expected that Series  shareholders 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 the
Series.

The Series will be subject to a 4% non-deductible  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.  The Series intends
to  distribute  to  shareholders  each  year an  amount  adequate  to avoid  the
imposition of such excise tax. Dividends paid by the Series will qualify for the
dividends-received  deduction  for  corporations  to the extent they are derived
from dividends paid by domestic corporations.

Gains and losses realized by the 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

                                                         9

<PAGE>


reduced by the net amount, if any, of such foreign exchange losses.

If the 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 Fund or its  shareholders  in respect of
deferred taxes arising from such distributions or gains.

If the  Series  were to invest  in a passive  foreign  investment  company  with
respect  to  which  the  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 fund,  even if such amount were not distributed
to the Series.

                                       8.
                           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 G1 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.

                    The general effect of these statutes is to protect officers,
                    directors  and   employees  of   Registrant   against  legal
                    liability


<PAGE>



                    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.

                    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


<PAGE>



                    Commission such  indemnification is against public policy as
                    expressed in the Act and is,  therefore,  unenforceable.  In
                    the event  that a claim  for  indemnification  against  such
                    liabilities  (other  than the payment by the  registrant  of
                    expense   incurred  or  paid  by  a  director,   officer  or
                    controlling  person  of the  registrant  in  the  successful
                    defense of any action,  suit or  proceeding)  is asserted by
                    such director,  officer or controlling  person in connection
                    with the securities being  registered,  the registrant will,
                    unless in the  opinion  of its  counsel  the matter has been
                    settled  by  controlling  precedent,  submit  to a court  of
                    appropriate   jurisdiction   the   question   whether   such
                    indemnification  by it is against public policy as expressed
                    in the Act and will be governed by the final adjudication of
                    such issue.
