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        5 years   10 years

Class A shares(4)       $67        $88            $111      $175
Class B shares(4)       $60        $91            $118      $209

(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 Fund, in the case of
Class A  shares  and (b) Lord  Abbett  Distributor  LLC,  in the case of Class B
shares.  (3)Although  the Fund 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 Fund (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 Fund to pay up to 0.50% in total annual fees,
half for  service  and the other  half for  distribution.  The 12b-1 fee for the
Class A shares has been estimated. (4)The annual operating expenses shown in the
summary are the actual  expenses for the fiscal year ended November 30, 1995 had
Lord,  Abbett & Co. not  waived  its  management  fee and  subsidized  all other
expenses of the Series.  The  foregoing  is provided to give  investors a better
understanding of the expenses that are incurred by an investment in the Fund.

4    HOW WE INVEST

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

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


<PAGE>


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

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

Up to 10% of our net  assets  (at the time of  investment)  may be  invested  in
foreign  securities (of the type described  herein)  primarily traded in foreign
countries.
For  securities  in our  portfolio  with a market value of up to 5% of our gross
assets at the time an option is written, we may write covered call options which
are traded on a national  securities  exchange  in an  attempt to  increase  our
income and to provide  greater  flexibility in the  disposition of our portfolio
securities.

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

We may invest in  closed-end  investment  companies  if bought in the  secondary
market with a fee or commission no greater than the customary brokers commission
in compliance with the Investment Company Act of 1940. Shares of such investment
companies  sometimes  trade at a discount  or premium in  relation  to their net
asset value and there may be  duplication  of fees,  for example,  to the extent
that we and the closed-end investment company both charge a management fee.

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

Neither an issuer's  ceasing to be rated investment grade nor a rating reduction
below that grade will  require  elimination  of a bond from our  portfolio.  For
temporary  defensive  purposes,  we 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.

We may invest up to 15% of our net  assets in  illiquid  securities.  Securities
determined by the Fund's Board of Directors to be liquid  pursuant to Securities
and  Exchange  Commission  Rule 144A  ("Rule  144A") will not be subject to this
limit.  Under  Rule144A,  a  qualifying  security  may be resold to a  qualified
institutional  buyer  without  registration  and  without  regard to whether the
seller  originally  purchased the security for investment.  Investments by us in
Rule 144A securities  initially determined to be liquid could have the effect of
diminishing  the level of our  liquidity  during  periods  of  decreased  market
interest in such securities.

<PAGE>


We may  deal in  financial  futures  transactions  with  respect  to the type of
securities described herein, including indices of such securities and options on
such financial futures. We will not enter into any futures contracts, or options
thereon,  if the  aggregate  market value of the  securities  covered by futures
contracts  plus  options  on such  financial  futures  exceeds  50% of our total
assets.

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. Securities markets of foreign countries in which we
may invest (up to 10% of our net assets)  generally  are not subject to the same
degree of  regulation  as the U.S.  markets  and may be more  volatile  and less
liquid  than  the  major  U.S.  markets.  There  may be less  publicly-available
information  on  publicly-traded  companies,  banks and  governments  in foreign
countries than generally is the case for such entities in the United States. The
lack of uniform  accounting  standards and practices among countries impairs the
validity of direct  comparisons of valuation  measures  (such as  price/earnings
ratios) for  securities in different  countries.  Other  considerations  include
political  and social  instability,  expropriation,  higher  transaction  costs,
currency fluctuations,  withholding taxes that cannot be passed through as a tax
credit  or  reduction  to  shareholders  and  different  securities   settlement
practices.

Foreign  securities  may be traded  on days  that we do not value our  portfolio
securities, and, accordingly,  our net asset value may be significantly affected
on days when shareholders do not have access to the Series.

Convertible bonds and convertible-preferred stocks tend to be more volatile than
straight bonds but less volatile and more income producing than their underlying
common stocks.


5    PURCHASES

ALTERNATIVE SALES ARRANGEMENTS
Classes of Shares.  The Fund 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.____ 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 Fund 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 Fund's 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 Fund. 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 Fund's 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.


<PAGE>


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 on a  hypothetical  investment  over time, and should
not be relied on as rigid guidelines.

Are There  Differences  in Account  Features  That Matter to You?  Some  account
features are available in whole or in part to Class A 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 waivers
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.

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.

GENERAL
How  Much  Must You  Invest?  You may buy our  shares  through  any  independent
securities  dealer having a sales  agreement with Lord Abbett  Distributor,  our
exclusive selling agent. Place your order with your investment dealer or send it
to Lord Abbett Research Fund, Inc. -- Large-Cap Series (P.O. Box 419100,  Kansas
City,  Missouri  64141).  The minimum  initial  investment  is $1,000 except for
Invest-A-Matic  and  Div-Move  ($250  initial and $50  subsequent  minimum)  and
Retirement  Plans ($250 minimum).  See "Shareholder  Services".  For information
regarding  the proper form of a purchase or redemption  order,  call the Fund at
800-821-5129.  This offering may be suspended, changed or withdrawn. Lord Abbett
Distributor reserves the right to reject any order.

The net asset value of our shares is  calculated  every  business  day as of the
close of the New York Stock  Exchange  ("NYSE")  by  dividing  net assets by the
number of shares  outstanding.  Securities  are valued at their  market value as
more fully described in the Statement of Additional Information.

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

<PAGE>


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

Buying  Class A  Shares.  The  offering  price of Class A shares is based on the
per-share  net asset value next  computed  after your order is  accepted  plus a
sales charge as follows.

</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 Fund with any share  purchases of any other  eligible Lord  Abbett-sponsored
fund, together with the current value at maximum offering price of any shares in
the Fund and in any eligible Lord Abbett-sponsored  funds held by the purchaser.
(Holdings  in the  following  funds are not  eligible  for the  above  rights of
accumulation:  Lord  Abbett  Equity  Fund  ("LAEF"),  Lord  Abbett  Series  Fund
("LASF"),  any series of 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 shares of the Fund or in
any of the above eligible funds. If the intended  purchases are completed during
the  period,  the total  amount of your  intended  purchases  of any shares will
determine the reduced sales charge rate for the Class A shares  purchased during
the period.  If not completed,  each Class A share purchase will be at the sales
charge for the aggregate of the actual share purchases.

Shares issued upon  reinvestment of dividends or distributions  are not included
in the statement of intention.  The term "purchaser" includes (i) an individual,
(ii) an  individual  and his or her spouse and children  under the age of 21 and
(iii) a trustee or other fiduciary  purchasing  shares for a single trust estate
or single  fiduciary  account  (including  a pension,  profit-sharing,  or other
employee  benefit trust qualified under Section 401 of the Internal Revenue Code
- -- more  than  one  qualified  employee  benefit  trust  of a  single  employer,
including its  consolidated  subsidiaries,  may be considered a single trust, as
may  qualified  plans of multiple  employers  registered in the name of a single
bank trustee as one account), although more than one beneficiary is involved.

Class A 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. We have adopted 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 Fund and (b) to sell Class A
shares  of the  Fund.  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").

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


<PAGE>


Holders of Class A shares on which the 1% sales  distribution  fee has been paid
will be required to pay to the Fund 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 Fund's Class A
shares by the other  fund.  The Fund 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 conncection with the distribution of
Class B shares,  including the payment and financing of sales  commisisons.  See
"Class B Rule 12b-1 Plan" below.

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

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

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 Fund 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,  and (iii) in connection with mandatory  distributions
under 403(b) plans and individual retirement accounts.

Class B Rule 12b-1  Plan.  The Fund has  adopted a Class B share Rule 12b-1 Plan
(the "B Plan") under which the Fund  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 Fund of part of all of the
service fee payments.

The  0.75%  annual  distribution  fee is  paid  to Lord  Abbett  Distributor  to
compensate it for its services  rendered in connection with the  distribution of
Class B shares,  including  the  payment  and  financing  of sales  commissions.
Although Class B shares are sold without a front-end  sales charge,  Lord Abbett
Distributor pays authorized institutions responsible for sales of Class B shares
a sale  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 Fund 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.

<PAGE>



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
establishg  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  Large-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 G.  Morris,  Lord  Abbett
partner,  has been primarily  responsible  for the day-to-day  management of the
Fund since 1996,  although he has been involved with the Fund's management since
inception.  Prior to joining Lord Abbett in 1991,  Mr. Morris was Vice President
and Manager of Chase Manhattan Bank, N.A. Mr. Morris delegates management duties
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,
regardless of industry sector, market capitalization or Wall Street sponsorship.

We are  obligated  to pay Lord Abbett a monthly  fee based on average  daily net
assets for each month at the annual  rate of .75%.  This fee may be higher  than
that paid by other mutual  funds.  For the fiscal year ended  November 30, 1995,
Lord  Abbett  waived  $50,255  of its  management  fee and  assumed  $18,000  of
expenses.  Due to such  waiver,  the  effective  fee  paid to Lord  Abbett  as a
percentage  of average  daily net assets was at the annual rate of zero  percent
for such period.  This  effective fee would have been at the annual rate of .75%
had Lord Abbett not waived its management fee. In addition,  we pay all expenses
not  expressly  assumed by Lord  Abbett.  Our Class A share  ratio of  expenses,
including  management  fee expenses,  to average net assets for such fiscal year
was zero  percent.  This expense ratio would have been 1.02% had Lord Abbett not
waived its management  fee and paid all other expenses of the Fund.  Lord Abbett
will not  continue  to waive  such fees and pay such  expenses  for the  current
fiscal year.

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 Large-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 fiscal  year ended on  November  30,  1995 with a net asset value of $15.54,
which was 29.8%  higher  than the $11.97  price  recorded at the close of fiscal
1994 (after  adjustment for a capital gains  distribution of $.82 per share paid
in December  1994).  The Series  produced a total return of 32.8%  compared to a
36.9% return for the unmanaged S&P 500 Index.  Since  inception on June 3, 1992,
the Series  produced a total  return of 79.5%  versus 60.5% for the S&P 500 over
the same period.

Moderate  economic  growth and declining  interest  rates resulted in a positive
environment for stocks  throughout  fiscal 1995. The Series maintained its focus
on  undervalued  issues with  positive  fundamentals  and earnings  that are not
primarily  dependent  on  strong  economic  activity.   Currently,   significant
valuation  disparities  are not readily  apparent among  industries and sectors;
thus  our  ability  to  identify   undervalued  issues  will  drive  the  Fund's
performance in the first half of 1996.

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 Fund's total return.

This  Prospectus  does not constitute an offering in any  jurisdiction  in which
such offer is not  authorized  or in which the person  making  such offer is not
qualified to do so or to anyone to whom it is unlawful to make such offer.
No person is authorized to give any  information or to make any  representations

LORD ABBETT

Statement of Additional Information                              July 15, 1996


                                          Lord Abbett Research Fund, Inc.

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 July 15, 1996.

Large-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 July 12,  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 allocated these authorized  shares
of capital stock among the classes from time to time. Prior to July 12, 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 public for the first time on or about August
1, 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 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.

                       Investment Objectives and Policies

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

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

Non-Fundamental   Investment   Restrictions.   In  addition  to  the  investment
restrictions above which cannot be changed without shareholder approval, we also
are subject to the following  non-fundamental  investment  policies which may be
changed by the Board of Directors  without  shareholder  approval.  The Fund 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  Fund's  total  assets  would be
invested   in  such   securities   (this   restriction   shall   not   apply  to
mortgaged-backed  securities,  asset-backed  securities or obligations issued or
guaranteed by the U. S. Government, its agencies or instrumentalities); (6) hold
securities of any issuer if more than 1/2 of 1% of the securities of such issuer
are owned  beneficially  by one or more  officers or directors 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 Fund's total assets (included  within such limitation,  but not to exceed
2% of the Fund's total assets, are warrants which are not listed on the New York
or American  Stock  Exchange or a major  foreign  exchange);  (8) invest in real
estate limited  partnership  interests or interests in oil, gas or other mineral
leases, or exploration or other development  programs,  except that the Fund may
invest  in  securities  issued by  companies  that  engage in oil,  gas or other
mineral exploration or other development activities; (9) write, purchase or sell
puts, calls,  straddles,  spreads or combinations thereof,  except to the extent
permitted in the Fund's prospectus and statement of additional  information,  as
they may be

                                                         2

amended  from  time to time;  or (10)  buy from or sell to any of its  officers,
directors,  employees,  or its  investment  adviser  or  any  of  its  officers,
directors, partners or employees, any securities other than shares of the Fund's
common stock.

For the year ended  November 30, 1995,  the  portfolio  turnover rate was 37.17%
versus 43.85% for the prior year.

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.

Other Investment Restrictions (which can be changed without shareholder
approval)

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

Rights  and  Warrants.  We  may  invest  in  rights  and  warrants  to  purchase
securities.  Included  within that amount,  but not to exceed 2% of the value of
the  Series' net  assets,  may be  warrants  which are not listed on the NYSE or
American Stock Exchange.

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

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

Options and Financial Futures Transactions

General.  We may  engage  in  options  and  financial  futures  transactions  in
accordance  with our  investment  objective  and  policies.  Although we are not
currently  employing  such options and financial  futures  transactions,  we may
engage in such transactions in the future if it appears advantageous to us to do
so, in order to cushion the effects of  fluctuating  interest  rates and adverse
market  conditions.  The use of options  and  financial  futures,  and  possible
benefits and

                                                         3

<PAGE>



attendant risks, are discussed below, along with information  concerning certain
other investment policies and techniques.

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

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

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

Options on Financial Futures  Contracts.  We may purchase and write call and put
options on financial  futures  contracts.  An option on a futures contract gives
the purchaser the right, in return for the premium paid, to assume a position in
a futures  contract at a specified  exercise price at any time during the period
of the option.  Upon  exercise,  the writer of the option  delivers  the futures
contract to the holder at the  exercise  price.  We would be required to deposit
with our custodian initial margin and maintenance margin with respect to put and
call options on futures  contracts  written by us. Options on futures  contracts
involve risks similar to the risks relating to transactions in financial futures
contracts  described above.  Generally  speaking,  a given dollar amount used to
purchase  an option on a financial  futures  contract  can hedge a much  greater
value of underlying securities than if that amount were used

                                                         4

to directly purchase the same financial  futures.  Should the event we intend to
hedge (or  protect)  against  not  materialize,  however,  the option may expire
worthless, in which case we would lose the premium paid therefor.

Segregated  Accounts.  To the extent  required  to comply  with  Securities  and
Exchange  Commission  Release  10666,  when  purchasing a futures  contract,  or
writing a put option, we will maintain in a segregated  account at our custodian
bank  liquid  high  grade  debt  obligations,  such as cash and U.S.  Government
Securities to cover our position.

                                       2.

1.  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.

"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 July 1, 1996 our officers and  directors as a group owned less than 20% of
our outstanding shares.

                     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 fiscal
years ended November 30, 1995, 1994, and 1993, respectively, this management fee
was waived by Lord Abbett and,  except for this waiver,  would have  amounted to
$50,255, $33,861 and $22,408, respectively.

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.  For the fiscal years
ended November 30, 1995, 1994 and 1993, respectively,  Lord Abbett, although not
obligated to, voluntarily assumed the above-mentioned  expenses which, if not so
assumed, would have amounted to $18,000, $18,000 and $13,500, respectively.

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 ("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.

                             Portfolio Transactions

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

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

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

                                                         8

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

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

For the fiscal  years ended  November  30,  1993,  1994 and 1995,  we paid total
commissions  to  independent  broker-dealers  of  $14,055,  $8,033  and  $7,832,
respectively.

                                       5.
                             Purchases, Redemptions
                            and Shareholder Services

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

As disclosed in the Prospectus, we calculate our net asset value as of the close
of the New York Stock  Exchange  ("NYSE")  on each day is a 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 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 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 November  30, 1995 was computed as
follows:

Net asset value per share (net assets divided
by shares outstanding).................................................$15.54

Maximum offering price per share (net asset
value divided by .9425)...............................................$16.49

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

                                                         9

<PAGE>



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 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 Fund 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 to  shareholders  by
authorized institutions than would otherwise be the case. The B Plan was 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.  The charges described below apply upon early
redemption  of  shares,  and  consist  of a  Contingent  Deferred  Sales  Charge
("CDSC"),  regardless  of class,  (i) will not apply to shares  purchased by the
reinvestment of dividends or capital gains distributions;  (ii) 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 (iii) are 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).

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:



                                                        10

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 received.

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 or beneficiaries from employer-sponsored retirement plans under the
Internal  Revenue  Code  for  benefit  payments  due  to  plan  loans,  hardship
withdrawals,  death,  retirement or  separation  from service and for returns of
excess contributions to retirement plan sponsors. In the case of Class A shares,
the CDSC is received by the Fund and is intended to  reimburse  all or a portion
of the amount  paid by the Fund if the shares are  redeemed  before the Fund has
had an  opportunity  to realize the  anticipated  benefits of having a long-term
shareholder  account  in the Fund.  In the case of Class B  shares,  the CDSC is
received by Lord Abbett Distributor and is intended to reimburse its expenses of
providing  distribution-related service to the Fund (including recoupment of the
commission  payments made) in connection  with the sale of Class B shares before
Lord  Abbett  Distributor  has had an  opportunity  to realize  its  anticipated
reimbursement  by having such a long-term  shareholder  account subject to the B
Plan distribution fee.

The other funds and series which participate in the Telephone Exchange Privilege
(except (a) Lord Abbett U.S.  Government  Securities  Money  Market  Fund,  Inc.
("GSMMF"),  (b)  certain  series of Lord  Abbett  Tax-Free  Income Fund and Lord
Abbett  Tax-Free  Income Trust for which a Rule 12b-1 Plan is not yet in effect,
and (c) any authorized  institution's  affiliated  money market fund  satisfying
Lord  Abbett  Distributor  as to certain  omnibus  account  and other  criteria,
hereinafter  referred  to  as  an  "authorized  money  market  fund"  or  "AMMF"
(collectively,  the "Non-12b-1 Funds")) have instituted a CDSC for each class on
the same terms and conditions.  No CDSC will be charged on an exchange of shares
of the same class between Lord Abbett funds or between such funds and AMMF. Upon
redemption of shares out of the Lord Abbett family of funds or out of AMMF,  the
CDSC  will be  charged  on  behalf  of and  paid:  (i) to the fund in which  the
original  purchase  (subject  to a CDSC)  occurred,  in the case of the  Class A
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.


                                                        11

<PAGE>



In no event will the amount of the CDSC exceed the Applicable CDSC 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 Fund being exchanged must have a value equal to at least
the  minimum  initial  investment  required  for the other  fund into  which the
exchange is made.

Shareholders in other Lord  Abbett-sponsored  funds and AMMF have the same right
to  exchange  their  shares for the  corresponding  class of 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 Lord Abbett
Research 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,

                                                        12

back-end  or  level  sales  charge)  so  that a  current  investment,  plus  the
purchaser's holdings valued at the current maximum offering price, reach a level
eligible for a discounted sales charge for Class A shares.

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

                                                        13

<PAGE>



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 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.

                                       6.
                                Past Performance

The Series  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 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 Fund's  investment
result for that class for the time  period  shown  (unless  the total  return is
shown at net asset value).  For Class C shares,  the 1.0% CDSC is applied to the
Fund's investment result for that class

                                                        14

<PAGE>



for the time period shown prior to the first anniversary of purchase (unless the
total return is shown at net asset  value).  Total  returns also assume that all
dividends and capital gains  distributions  during the period are  reinvested at
net asset value per share, and that the investment is redeemed at the end of the
period.  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 one year ended, and the life-of-series periods (from commencement
of  operations  on June 3, 1992  through)  November  30, 1995  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 25.20% and 16.26% and the
redeemable values were $1,252 and $1,693, respectively.

Our yield  quotation  is based on a 30-day  period  ended on a  specified  date,
computed by  dividing  our net  investment  income per share  earned  during the
period by our  maximum  offering  price per share on the last day of the period.
This is determined by finding the following quotient:  take the Fund's dividends
and interest earned during the period minus its expenses  accrued for the period
and  divide by the  product  of (i) the  average  daily  number  of Fund  shares
outstanding  during the period that were entitled to receive  dividends and (ii)
the Fund's maximum  offering  price per share 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 Fund's net
asset value per share.
Yields for Class B and C shares do not reflect the deduction of the CDSC.

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

                                       7.
                                      Taxes

The value of any shares  redeemed by 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

                                                        15

<PAGE>


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.

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.

                                       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 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


<PAGE>



                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
                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


<PAGE>



                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
                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.

                             ARTICLES OF AMENDMENT


          LORD ABBETT RESEARCH FUND, INC., a Maryland corporation (hereinafter
called the "Corporation"), hereby certifies to the State Department of
Assessments and Taxation of Maryland, that:

          FIRST: The Articles of Incorporation of the Corporation (hereinafter
called the "Articles") are hereby amended by:

     (a)  Striking out Section 1 of ARTICLE V and inserting in lieu thereof:

     "SECTION 1.  The total number of shares which the Corporation has authority
to issue is 1,000,000,000 shares of capital stock of the par value of $.001 each
(the "Shares"), having an aggregate par value of $1,000,000.  The Board of
Directors of the Corporation shall have full power and authority, from time to
time, to classify or reclassify any unissued Shares, including, without
limitation, the power to classify or reclassify unissued shares into series, and
to classify or reclassify a series into one or more classes of stock that may be
invested together in the common investment portfolio in which the series is
invested, by setting or changing the preferences, conversion or other rights,
voting powers, restrictions, limitations as to dividends, qualifications, or
terms or conditions of redemption of such shares of stock.  All Shares of a
series shall represent the same interest in the Corporation and have the same
preferences, conversion or other rights, voting powers, restrictions,
limitations as to dividends, qualifications, and terms and conditions of
redemption as the other Shares of that series, except to the extent that the
Board of Directors provides for differing preferences, conversion or other
rights, voting powers, restrictions, limitations as to dividends,
qualifications, or terms or conditions of redemption of Shares of classes of
such series as determined pursuant to Articles Supplementary filed for record
with the State Department of Assessments and Taxation of Maryland, or as
otherwise determined pursuant to these Articles or by the Board of Directors in
accordance with law.  The Shares shall initially be classified into three series
designated initially as the "Large-Cap Series", consisting of 50,000,000 Shares,
the "Mid-Cap Series", consisting of 50,000,000 Shares and the "Small-Cap
Series", consisting
<PAGE>
 
of 50,000,000 Shares.  Prior to the first classification of a series into
additional classes, all outstanding Shares of such series shall be of a single
class.  Notwithstanding any other provision of these Articles, upon the
classification of unissued Shares into additional series, the Board of Directors
shall specify a legal name for the new series in appropriate charter documents
filed for record with the State Department of Assessments and Taxation of
Maryland providing for such name change and classification, and upon the first
classification of a series into additional classes, the Board of Directors shall
specify a legal name for the outstanding class, as well as for the new class or
classes, in appropriate charter documents filed for record with the State
Department of Assessments and Taxation of Maryland providing for such name
change and classification."

(b) Striking out Section 2 of ARTICLE V and inserting in lieu thereof:

          "SECTION 2.  A description of the relative preferences, conversion and
other rights, voting powers, restrictions, limitations as to dividends,
qualifications and terms and conditions of redemption of all series and classes
of series of Shares is as follows, unless otherwise set forth in Articles
Supplementary filed for record with the State Department of Assessments and
Taxation of Maryland or otherwise determined pursuant to these Articles:

          (a) Assets Belonging to Series.  All consideration received or
              --------------------------                                
receivable by the Corporation for the issue or sale of Shares of a particular
series, together with all assets in which such consideration is invested or
reinvested, all income, earnings, profits and proceeds thereof, including any
proceeds derived from the sale, exchange or liquidation of such assets, and any
funds or payments derived from any reinvestment of such proceeds in whatever
form the same may be, shall irrevocably belong to that series for all purposes,
subject only to the rights of creditors, and shall be so recorded upon the books
of account of the Corporation.  Such consideration, assets, income, earnings,
profits and proceeds, including any proceeds derived from the sale, exchange or
liquidation of such assets, and any funds or payments derived from any
reinvestment of such proceeds in whatever form the same may be, together with
any unallocated items (as

                                       2
<PAGE>
 
hereinafter defined) relating to that series as provided in the following
sentence, are herein referred to as "assets belonging to" that series.  In the
event that there are any assets, income, earnings, profits or proceeds thereof,
funds or payments which are not readily identifiable as belonging to any
particular series (collectively "Unallocated Items"), the Board of Directors
shall allocate such Unallocated Items to and among any one or more of the series
created from time to time in such manner and on such basis as it, in its sole
discretion, deems fair and equitable; and any Unallocated Items so allocated to
a particular series shall belong to that series. Each such allocation by the
Board of Directors shall be conclusive and binding upon the stockholders of all
series for all purposes.

          (b) Liabilities Belonging to Series.  The assets belonging to each
              -------------------------------                               
particular series shall be charged with the liabilities of the Corporation in
respect of that series, including any class thereof, and with all expenses,
costs, charges and reserves attributable to that series, including any such
class, and shall be so recorded upon the books of account of the Corporation.
Such liabilities, expenses, costs, charges and reserves, together with any
unallocated items (as hereinafter defined) relating to that series, including
any class thereof, as provided in the following sentence, so charged to that
series, are herein referred to as "liabilities belonging to" that series.  In
the event there are any unallocated liabilities, expenses, costs, charges or
reserves of the Corporation which are not readily identifiable as belonging to
any particular series (collectively "Unallocated Items"), the Board of Directors
shall allocate and charge such Unallocated Items to and among any one or more of
the series created from time to time in such manner and on such basis as the
Board of Directors in its sole discretion deems fair and equitable; and any
Unallocated Items so allocated and charged to a particular series shall belong
to that series.  Each such allocation by the Board of Directors shall be
conclusive and binding upon the stock holders of all series for all purposes.
To the extent

                                       3
<PAGE>
 
determined by the Board of Directors, liabilities and expenses relating solely
to a particular class (including, without limitation, distribution expenses
under a Rule 12b-1 plan and administrative expenses under an administration or
service agreement, plan or other arrangement, however designated, which may be
adopted for such class) shall be allocated to and borne by such class and shall
be appropriately reflected (in the manner determined by the Board of Directors)
in the net asset value, dividends and distributions and liquidation rights of
the shares of such class.

          (c) Dividends.  Dividends and distributions on Shares of a particular
              ---------                                                        
series may be paid to the holders of Shares of that series at such times, in
such manner and from such of the income and capital gains, accrued or realized,
from the assets belonging to that series, after providing for actual and accrued
liabilities belonging to that series, as the Board of Directors may determine.
Such dividends and distributions may vary between or among classes of a series
to reflect differing allocations of liabilities and expenses of such series
between or among such classes to such extent as may be provided in or determined
pursuant to Articles Supplementary filed for record with the State Department of
Assessments and Taxation of Maryland or as may otherwise be determined by the
Board of Directors.

          (d) Liquidation.  In the event of the liquidation or dissolution of
              -----------                                                    
the Corporation, the stockholders of each series shall be entitled to receive,
as a series, when and as declared by the Board of Directors, the excess of the
assets belonging to that series over the liabilities belonging to that series.
The assets so distributable to the stockholders of one or more classes of a
series shall be distributed among such stockholders in proportion to the
respective aggregate net asset values of the shares of such series held by them
and recorded on the books of the Corporation.

                                       4
<PAGE>
 
          (e) Voting.  On each matter submitted to vote of the stockholders,
              ------                                                        
each holder of a Share shall be entitled to one vote for each such Share
standing in his name on the books of the Corporation irrespective of the series
or class thereof and all shares of all series and classes shall vote as a single
class ("Single Class Voting"); provided, however, that (i) as to any matter with
                                                        -                       
respect to which a separate vote of any series or class is required by the
Investment Company Act of 1940, as amended from time to time, applicable rules
and regulations thereunder, or the Maryland General Corporation Law, such
requirement as to a separate vote of that series or class shall apply in lieu of
Single Class Voting as described above; (ii) in the event that the separate vote
                                         --                                     
requirements referred to in (i) above apply with respect to one or more (but
less than all) series or classes, then, subject to (iii) below, the shares of
all other series and classes shall vote as a single class; and (iii) as to any
                                                                ---           
matter which does not affect the interest of a particular series or class, only
the holders of shares of the one or more affected series or classes shall be
entitled to vote.

          (f) Conversion.  At such times (which times may vary among shares of a
              ----------                                                        
class) as may be determined by the Board of Directors, Shares of a particular
class of a series may be automatically converted into Shares of another class of
such series based on the relative net asset values of such classes at the time
of conversion, subject, however, to any conditions of conversion that may be
imposed by the Board of Directors.

          (g) Equality.  All Shares of each particular series shall represent an
              --------                                                          
equal proportionate interest in the assets belonging to that series (subject to
the liabilities belonging to that series), but the provisions of this sentence
or any other provision of these Articles shall not restrict any distinctions
that may exist with respect to stockholder elections to receive dividends or
distributions in cash or Shares or that may otherwise exist with respect to
dividends and distributions on Shares of the same series."

     (e)  Striking out the words "Class" or "Class or Classes", as the case may

so interested may be counted in determining the existence of a quorum at any
meeting of the Board of Directors which shall authorize any such agreement, and

and regulations thereunder, or any other applicable Act of Congress hereafter
enacted, and no amendment to any agreement entered into pursuant to said
subsection (e) (other than an amendment reducing the compensation of the other
party thereto) shall be effective unless assented to by the affirmative vote of
a majority of the outstanding voting securities of the Corporation (as such
phrase is defined in the Investment Company Act of 1940, as amended from time to
time) entitled to vote on the matter."

     (g)  Striking out the preamble to Section 3 of Article VII and the portion

          "SECTION 3.  For the purposes referred to in these Articles of
Incorporation, the net asset value of shares of the capital stock of the
Corporation of each series and class as of any particular time (a "determination
time") shall be determined by or pursuant to the direction of the Board of
Directors as follows:

          (a) At times when a series is not classified into multiple classes,
the net asset value of each share of stock of a series, as of a determination
time, shall be the quotient, carried out to not less than two decimal points,
obtained by dividing the net value of the assets of the Corporation belonging to
that series (determined as hereinafter provided) as of such determination time
by the total number of shares of that series then outstanding, including all
shares of that series which the Corporation has agreed to sell for which the
price has been

                                       7
<PAGE>
 
determined, and excluding shares of that series which the Corporation has agreed
to purchase or which are subject to redemption for which the price has been
determined.

The net value of the assets of the Corporation of a series as of a determination
time shall be determined in accordance with sound accounting practice by
deducting from the gross value of the assets of the Corporation belonging to
that series (determined as hereinafter provided), the amount of all liabilities
belonging to that series (as such terms are defined in subsection (b) of Section
2 of Article V), in each case as of such determination time.

The gross value of the assets of the Corporation belonging to a series as of
such determination time shall be an amount equal to all cash, receivables, the
market value of all securities for which market quotations are readily available
and the fair value of other assets of the Corporation belonging to that series
(as such terms are defined in subsection (a) of Section 2 of Article V) at such
determination time, all determined in accordance with sound accounting practice
and giving effect to the following:"

     (h)  Adding a new subsection (b) to Section 3 of Article VII (and
renumbering subsection (b) as subsection (c)), as follows:

     "(b)  At times when a series is classified into multiple classes, the net
asset value of each share of stock of a class of such series shall be determined
in accordance with subsections (a) and (c) of this Section 3 with appropriate
adjustments to reflect differing allocations of liabilities and expenses of such
series between or among such classes to such extent as may be provided in or
determined pursuant to Articles Supplementary filed for record with the State
Department of Assessments and Taxation of Maryland or as may otherwise be
determined by the Board of Directors."

     (i)  Striking out Section 4 of Article VII and inserting in lieu thereof:

                                       8
<PAGE>
 
          "SECTION 4.  The presence in person or by proxy of the holders of one-
third of the Shares issued and outstanding and entitled to vote thereat shall
constitute a quorum for the transaction of any business at all meetings of the
shareholders, except as otherwise provided by law or in these Articles of
Incorporation and except that where the holders of Shares of any series or class
are entitled to a separate vote as such series or class (each such series or
class, a "Separate Class") or where the holders of Shares of two or more (but
not all) series or classes are required to vote as a single series or class
(each such single series or class, a "Combined Class"), the presence in person
or by proxy of the holders of one-third of the Shares of that Separate Class or
Combined Class, as the case may be, issued and outstanding and entitled to vote
thereat shall constitute a quorum for such vote.  If, however, a quorum with
respect to all series, including all classes thereof, a Separate Class or a
Combined Class, as the case may be, shall not be present or represented at any
meeting of the shareholders, the holders of a majority of the Shares of all
series, such Separate Class or such Combined Class, as the case may be, present
in person or by proxy and entitled to vote shall have power to adjourn the
meeting from time to time as to all series, such Separate Class or such Combined
Class, as the case may be, without notice other than announcement at the
meeting, until the requisite number of Shares entitled to vote at such meeting
shall be present.  At such adjourned meeting at which the requisite number of
Shares entitled to vote thereat shall be represented any business may be
transacted which might have been transacted at the meeting as originally
notified.  The absence from any meeting of stockholders of the number of Shares
in excess of one-third of the Shares of all series or classes, or of the
affected series or classes, as the case may be, which may be required by the
laws of the State of Maryland, the Investment Company Act of 1940 or any other
applicable law, or by these Articles of Incorporation, for action upon any given
matter shall not prevent action at such meeting upon any other matter or matters
which may properly come before the meeting, if there shall be present thereat,
in person or by proxy, holders of the number of Shares required for action in
respect of such other matter or matters."

     (j)  Striking out Section 5 of Article VII and inserting in lieu thereof:

          "SECTION 5.  Any determination as to any of the following matters made
by or pursuant to the direction of the Board of Directors

                                       9

consistent with these Articles of Incorporation and in the absence of willful
misfeasance, bad faith, gross negligence or reckless disregard of duties, shall
be final and conclusive and shall be binding upon the Corporation and every
holder of the Shares, of any series or class, namely, the amount of the assets,
obligations, liabilities and expenses of the Corporation or belonging to any
series or with respect to any class; the amount of the net income of the
Corporation from dividends and interest for any period and the amount of assets
at any time legally available for the payment of dividends with respect to any
series or class; the amount of paid-in surplus, other surplus, annual or other
net profits, or net assets in excess of capital, undivided profits, or excess of
profits over losses on sales of securities belonging to the Corporation or any
series or class; the amount, purpose, time of creation, increase or decrease,
alteration or cancellation of any reserves or charges and the propriety thereof
(whether or not any obligation or liability for which such reserves or charges
shall have been created shall have been paid or discharged) with respect to the
Corporation or any series or class; the market value, or any sale, bid or asked
price to be applied in determining the market value, of any security owned or
held by the Corporation; the fair value of any asset owned by the Corporation;
the number of Shares of the Corporation of any series or class issued or
issuable; the existence of conditions permitting the postponement of payment of
the repurchase price of Shares of any series or class or the suspension of the
right of redemption as provided by law; any matter relating to the acquisition,
holding and disposition of securities and other assets by the Corporation; any
question as to whether any transaction constitutes a purchase of securities on
margin, a short sale of securities, or an underwriting of the sale of, or
participation in any underwriting or selling group in connection with the public
distribution of any securities; and any matter relating to the issue, sale,
repurchase and/or other acquisition or disposition of Shares of any series or
class."

      (k)  Striking out the words "of all Classes or of the affected Classes, as
the case may be," from Article IX.

          SECOND:  The Board of Directors of the Corporation on March 14, 1996,
