Our investment  objective is long-term  growth of capital  through a diversified

primarily in the common stocks of companies with  long-range  growth  potential,
particularly  smaller companies considered to be in the developing growth phase.
There can be no assurance  that our objective  will be achieved.  Volatile price
movement can be expected.

charge,  by writing to the Fund or by calling  800-874-3733.  Ask for "Part B of

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

assuming redemption on the last day of each period indicated.

                          1 year     3 years     5 years     10 years

<FN>

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

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

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

(4)The annual  operating  expenses  shown in the summary have been restated from
January 31, 1997 fiscal year amounts to reflect current fees.

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

Our present  investment  strategy,  as  developed by Lord,  Abbett & Co.  ("Lord
Abbett"),  our  investment  manager,  is based on the four  phases of  corporate
growth.  As described  below,  only the second (or  developing  growth) phase is
characterized by a dramatic rate of growth.  We look for companies in that phase
and, under normal circumstances, will invest at least 65% of our total assets in
securities of such companies. We also may invest in companies which are in their
formative phase.  Developing  growth companies are almost always small,  usually
young and their  shares  are  generally  traded  over the  counter.  Having,  in
management's view, passed the pitfalls of the formative years, they are now in a
position to grow rapidly in their market.

THE FOUR PHASES OF  BUSINESS  GROWTH (as  perceived  by Lord  Abbett)  Phase 1--
Formative:  Phase 1 has high risk. It is a formative phase for companies and the
perils of infancy take a high toll during these years.  Skill of management  and
growth of revenues  and  earnings  permit some  companies to survive and advance
into the second phase.

Phase 2 -- Developing Growth:  Phase 2 usually is a period of swift development,
when growth occurs at a rate rarely  equaled by  established  companies in their
mature years. We focus on companies which we believe are strongly  positioned in
this phase. Of course,  the actual growth of a company cannot be foreseen and it
may be difficult to determine in which phase a company is presently situated.

Phase 3--  Established  Growth:  Phase 3 is a time of  established  growth  when
competitive  forces,  regulations and internal  bureaucracy often begin to blunt
the sharp edge of success in the marketplace.

Phase 4--  Maturity:  Phase 4 is a time of maturity when  companies  ease into a
growth pattern that roughly reflects the increase in Gross Domestic Product.

At any given time,  there are many hundreds of  publicly-traded  corporations in
the  developing  growth  phase.  In  choosing  among  them,  we look for special
characteristics  that will help their growth. These can include a unique product
or service for which we foresee a rising demand; a special area of technological
expertise;  the ability to service a region that is growing faster than average;
a competitive  advantage or new  opportunities  in foreign trade or arising from
shifts in government priorities and programs; or an ability to take advantage of
growth of consumers' discretionary income and demographic changes.

We also look for certain financial charac-teristics such as: at least five years
of   higher-than-average   growth  of   revenues   and   earnings   per   share;
higher-than-average returns on equity; the ability to finance growth in the form
of a  lower-than-average  ratio of long-term debt to capital and  price/earnings
ratios that are below expected growth rates.

We also look for certain characteristics of management in addition to those that
are implied by the financial data. We look for management that is  well-seasoned
and  diverse  in  its  talent  and  that  is  aggressive  enough  to  seize  the
opportunities  we  perceive  in each  company's  future.  Finally,  we look  for
management  that has  demonstrated  an ability to manage through a full economic
cycle. We do not, however, invest in order to control management.

Securities  we consider for our  portfolio  are analyzed  solely on  traditional
investment  fundamentals.  We do not select securities based on trends indicated
by chartists'  technical  analyses.  In addition to the  financial  data already
mentioned,  we evaluate the market for each company's products or services,  the
strengths and  weaknesses of  competitors,  the  availability  of raw materials,
diversity of product mix, etc. Finally,  in assembling our portfolio,  we try to
diversify our investments. Within the bounds of other criteria, we try to invest
in many securities and industries in order to minimize risk.

Up to 10% of our net  assets  (at the time of  investment)  may be  invested  in
foreign  securities (of the type described  above)  primarily  traded in foreign
countries.

<PAGE>

Although we have no present plans to change our policies,  if we determine  that
our investment objective can best be achieved by a change in investment policies
or  strategy,  we reserve  the right to make such a change  without  shareholder
approval,  provided  it is not  prohibited  by our  investment  restrictions  or
applicable  law.  Any  material  change  will  first be  disclosed  in a current
prospectus.

There may be times when management  believes that economic conditions or general
levels of common stock prices are such that it would be advisable, for defensive
reasons,  to curtail  investments in common stocks.  During such periods, we may
invest  a  substantial  portion  of our  portfolio  in cash or cash  equivalents
(short-term obligations of banks, corporations or the U.S. Government).

We will not change our investment objective without shareholder approval.

RISK FACTORS. An investment in the Fund is not intended as a complete investment
program. The Fund will not provide significant income. Moreover,  because stocks
of developing  growth  companies  entail more risk and have more volatile prices
than those of mature  companies,  the Fund's net asset value per share is likely
to experience above-average fluctuations.

Securities  markets of foreign  countries in which the Fund may invest generally
are not subject to the same degree of regulation as the U.S.  markets and may be
more volatile and less liquid than the major U.S. markets. Lack of liquidity may
affect the Fund's  ability to purchase or sell large  blocks of  securities  and
thus obtain the best price. There may be less publicly-available  information on
publicly-traded  companies,  banks and governments in foreign  countries than is
generally the case for such entities in the United  States.  The lack of uniform
accounting  standards  and  practices  among  countries  impairs the validity of
direct  com-parisons of valuation  measures (such as price/earnings  ratios) for
securities in different countries.  Other  considerations  include political and
social instability,  expropriation, higher transaction costs, foreign government
controls, currency fluctuations, withholding taxes that cannot be passed through
as a tax credit or deduction to shareholders and different securities settlement
practices. Settlement periods for foreign securities, which are sometimes longer
than those for securities of U.S. issuers, may affect portfolio liquidity. These
different settlement practices may cause missed purchasing  opportunities and/or
the loss of interest on money market and debt investments pending further equity
or long-term debt investments.  In addition, foreign securities held by the Fund
may be traded on days  that the Fund  does not value its  portfolio  securities,
such as Saturdays and customary business holidays, and, accordingly,  the Fund's
net asset value may be significantly  affected on days when  shareholders do not
have access to the Fund.

PORTFOLIO  TURNOVER.  The  portfolio  turnover  rate for the  fiscal  year ended
January 31, 1997 was 42.35%, compared to 50.12% for the prior fiscal year.

5 PURCHASES

ALTERNATIVE SALES ARRANGEMENTS

CLASSES OF SHARES.  The Fund offers investors three different classes of shares.
The different  classes of shares represent  investments in the same portfolio of
securities  but  are  subject  to  different  expenses  and are  likely  to 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 or on investments that
do not qualify to be under a "special  retirement  wrap  program"  defined under
"Class A Share Net Asset Value Purchases" below). 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 or under a "special  retirement  wrap program") 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

<PAGE>

charge  ("CDSC") of 1% except for redemptions  under a "special  retirement wrap
program." Class A shares are subject to service and  distribution  fees that are
currently estimated to total annually approximately 0.23 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  under
"General" below.

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

CLASS C SHARES.  If you buy Class C shares,  you pay no sales charge at the time
of  purchase,  but if you redeem your  shares  before the first  anniversary  of
buying  them,  you will  normally  pay the Fund a CDSC of 1%. Class C shares are
subject to service and  distribution  fees at an annual rate of 1% of the annual
net  asset  value of the  Class C  shares.  The CDSC  and the  Rule  12b-1  plan
applicable to the C shares are described under "General" 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, Class B and Class C shares,  and considered the effect of the higher
distribution  fees on Class B and  Class C  expenses  (which  will  affect  your
investment  return). Of course, the actual performance of your investment cannot
be predicted and will vary, based on 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.

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

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

<PAGE>

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

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

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

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

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

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

GENERAL

HOW  MUCH  MUST YOU  INVEST?  You may buy our  shares  through  any  independent
securities  dealer having a sales  agreement with Lord Abbett  Distributor,  our
exclusive selling agent. Place your order with your investment dealer or send it
to Lord Abbett  Developing  Growth Fund,  Inc.  (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
Individual Retirement Accounts ($250 minimum).  For Retirement Plans there is no
minimum initial investment required. See "Shareholder Services." For information
regarding  the proper form of a purchase or redemption  order,  call the Fund at
800-821-5129.  This offering may be suspended, changed or withdrawn. Lord Abbett
Distributor  reserves the right to reject any order.  The net asset value of our
shares is  calculated  every  business day as of the close of the New York Stock
Exchange  ("NYSE") by dividing  net assets by the number of shares  outstanding.
Securities  are  valued at their  market  value as more fully  described  in the
Statement of Additional Information.

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

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

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.

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

CLASS A 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

<PAGE>

Lord Abbett-sponsored funds who consent to such purchase if such persons provide
services to Lord Abbett,  Lord Abbett  Distributor or such funds on a continuing
basis and are  familiar  with such fund;  (f) through  Retirement  Plans with at
least 100 eligible employees and (g) through a "special retirement wrap program"
sponsored  by an  authorized  institution  having  one or  more  characteristics
distinguishing  it, in the opinion of Lord Abbett Distributor from a mutual fund
wrap fee program.  Such  characteristics  include,  among other things, the fact
that  an  authorized  institution  does  not  charge  its  clients  any fee of a
consulting  or  advisory   nature  that  is   economically   equivalent  to  the
distribution  fee  under a Class A 12b-1  Plan  and the fact  that  the  program
relates to participant-directed Retirement Plans.

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%, except that the
service fee may not exceed 0.15 of 1% in the case of shares sold or attributable
to shares sold prior to June 1, 1990 (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  and (2) a  one-time
distribution fee of up to 1% (reduced according to the following schedule: 1% of
the first $5 million,  .55% of the next $5 million, .50% of the next $40 million
and .25% over $50  million),  payable  at the time of sale on all Class A shares
sold during any  12-month  period  starting  from the day of the first net asset
value sale (i) at the $1 million  level by  authorized  institutions,  including
sales qualifying at such level under the rights of accumulation and statement of
intention  privileges;  (ii) through Retirement Plans with at least 100 eligible
employees or (iii)  constituting new sales pursuant to a special retirement wrap
program and excluding exchanges into the Fund under such a program. 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.

Holders of Class A shares on which the 1% sales  distribution  fee has been paid
may 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.  (Exceptions  are made for: (i)  redemptions by
Retirement  Plans  due to any  benefit  payment  such  as Plan  loans,  hardship
withdrawals, death, retirement or

<PAGE>

separation from service with respect to plan participants or the distribution of
any  excess  contributions  and  (ii)  participant  directed  redemptions  which
continue  as program  investments  in another  fund  participating  in a special
retirement wrap program.) 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 may be deducted from
the redemption proceeds. That sales charge will not apply to shares purchased by
the reinvestment of dividends or capital gains distributions. The charge will be
assessed  on the  lesser  of the net  asset  value of the  shares at the time of
redemption  or the  original  purchase  price.  The Class B CDSC is paid to Lord
Abbett Distributor to compensate it for its services rendered in connection with
the distribution of Class B shares, including the payment and financing of sales
commissions. See "Class B Rule 12b-1 Plan" below.

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

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

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%
- -----------------------------------------------

- -----------------------------------------------
3rd             4th              3.0%
- -----------------------------------------------
4th             5th              2.0%
- -----------------------------------------------

- -----------------------------------------------
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; (iii) in connection with mandatory distributions under
403(b) plans and individual retirement accounts; and (iv) in connection with the
death of an individual shareholder (a natural person).

<PAGE>

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  (except as to certain
accounts for which tracking data is not available)  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 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 or all of the
service fee payments.

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

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  does not intend to make a profit
under  the B  Plan,  the  B  Plan  is  considered  a  compensation  plan  (i.e.,
distribution  fees are paid  regardless of expenses  incurred) in order to avoid
the   possibility  of  Lord  Abbett   Distributor  not  being  able  to  receive
distribution fees because of a temporary timing difference between its incurring
expenses and receipt of such distribution fees.

AUTOMATIC  CONVERSION  OF CLASS B  SHARES.  On the  eighth  anniversary  of your
purchase of Class B shares,  those shares will automatically  convert to Class A
shares.  This  conversion  relieves  Class B  shareholders  of the higher annual
distribution  fee that  applies  to Class B shares  under the Class B Rule 12b-1
Plan.  The  conversion  is based on the  relative  net  asset  values of the two
classes,  and no sales  charge or other  charge is imposed.  When Class B shares
convert,  any other Class B shares that were  acquired  by the  reinvestment  of
dividends and distributions will also convert to

<PAGE>

Class A shares on a pro rata  basis.  The  conversion  feature is subject to the
continued  availability  of an opinion of counsel or a tax ruling  described  in
"Purchases, Redemptions and Shareholder Services" in the Statement of Additional
Information.

BUYING  CLASS C SHARES.  Class C shares  are sold at net  asset  value per share
without an initial  sales  charge.  However,  if Class C shares are redeemed for
cash  before  the  first  anniversary  of their  purchase,  a CDSC of 1% will be
deducted from the redemption proceeds.  That reimbursement charge will not apply
to  shares   purchased  by  the  reinvestment  of  dividends  or  capital  gains
distributions.  The charge will be assessed on the lesser of the net asset value
of the shares at the time of  redemption  or the original  purchase  price.  The
Class C CDSC is paid to the Fund to reimburse  it, in whole or in part,  for the
service and  distribution  fee payments made by the Fund at the time such shares
were sold, as described 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 for one year or more and (3) shares
held the longest  before the first  anniversary  of their  purchase.  If Class C
shares are exchanged into the same class of another Lord  Abbett-sponsored  fund
and  subsequently  redeemed  before  the  first  anniversary  of their  original
purchase,  the  charge  will be  collected  by the other  fund on behalf of this
Fund's  Class C  shares.  The Fund will  collect  such a charge  for other  Lord
Abbett-sponsored funds in a similar situation.

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

6 SHAREHOLDER SERVICES

We offer the following shareholder services:

Telephone  Exchange  Privilege:  Shares of any class 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,  LASF and  LARF and (ii)  certain
tax-free,  single-state series where the exchanging shareholder is a resident of
a state in which such  series is not  offered for sale and (b) for shares of any
authorized  institution's  affiliated  money market fund  satisfying Lord Abbett
Distributor  as  to  certain  omnibus  account  and  other  criteria  (together,
"Eligible Funds").

You or your representative  with proper  identification can instruct the Fund to
exchange  uncertificated  shares  of a class  (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  class  share on that day.
Expedited  exchanges  by  telephone  may be  difficult  to implement in times of
drastic economic or market change.  The exchange privilege should not be used to
take advantage of

<PAGE>

short-term  swings in the market.  The Fund  reserves  the right to terminate or
limit the privilege of any  shareholder who makes frequent  exchanges.  The Fund
can  revoke the  privilege  for all  shareholders  upon 60 days'  prior  written
notice.  A prospectus for the other Lord  Abbett-sponsored  fund selected by you
should  be  obtained  and read  before an  exchange.  Exercise  of the  exchange
privilege  will be  treated  as a sale for  federal  income  tax  purposes  and,
depending on the circumstances, a capital gain or loss may be recognized.

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

INVEST-A-MATIC  :  You  can  make  fixed,   periodic  investments  ($50  minimum
investment)  into the Fund and/or any Eligible Fund by means of automatic  money
transfers from your bank checking account. You should read the prospectus of the
other fund before investing.

RETIREMENT  PLANS:  Lord  Abbett  makes  available   retirement  plan  documents
including 401(k) plans and custodial agreements for IRAs (Individual  Retirement
Accounts including Simple IRAs and Simplified Employee  Pensions),  403(b) plans
and pension and profit-sharing plans.

HOUSEHOLDING:  A single copy of an annual or semi-annual  report will be sent to
an address to which more than one  registered  shareholder  of the Fund with the
same last name has indicated mail is to be delivered,  unless additional reports
are specifically requested in writing or by telephone.

All  correspondence  should be directed to Lord Abbett  Developing  Growth Fund,
Inc. (P.O. Box 419100, Kansas City, Missouri 64141; 800-821-5129).

7 OUR MANAGEMENT

Our business is managed by our officers on a day-to-day  basis under the overall
direction  of our Board of Directors  with the advice of Lord Abbett.  We employ
Lord Abbett as  investment  manager  pursuant to a  Management  Agreement.  Lord
Abbett has been an investment  manager for over 67 years and  currently  manages
approximately  $22  billion  in a family  of mutual  funds  and  other  advisory
accounts.  Under  the  Management  Agreement,   Lord  Abbett  provides  us  with
investment  management  services and  executive  and other  personnel,  pays the
remuneration  of our officers  and 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

<PAGE>

Abbett-sponsored  funds having  various  investment  objectives and also advises
other investment clients.  Stephen J. McGruder,  Executive Vice President of the
Fund,  serves as portfolio  manager for the Fund and has done so since he joined
Lord Abbett in May 1995.  Prior to joining Lord Abbett,  Mr. McGruder had served
as Vice  President of Wafra  Investment  Advisory  Group,  a private  investment
company, since October 1988. Mr. McGruder has over 28 years of experience in the
investment business.

Under  the  Management  Agreement,  we pay Lord  Abbett a  monthly  fee based on
average  daily net assets for each month.  For the fiscal year ended January 31,
1997, the effective fee paid to Lord Abbett as a percentage of average daily net
assets was at the annual rate of 0.64%.  In  addition,  we pay all  expenses not
expressly assumed by Lord Abbett. Our Class A, B and C share ratios of expenses,
including  management  fee  expenses,  to average  net assets for the year ended
January 31, 1997 with respect to the Class A shares,  and for the period  August
1, 1996 through  January 31, 1997, with respect to the Class B and C shares were
1.10%, 0.93% and 0.93%, respectively.

THE FUND.  The Fund is a  diversified  open-end  management  investment  company
incorporated under Maryland law on August 28, 1978. Our predecessor  corporation
was organized on July 11, 1973. Its Class A, B and C shares have equal rights as
to voting,  dividends,  assets and liquidation except for differences  resulting
from certain class-specific expenses.

8 DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXES
Dividends  from net  investment  income  may be taken in cash or  reinvested  in
additional shares at net asset value without a sales charge.

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 date on which the dividend is paid.

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 paid in November and/or February.  You may take them
in cash or reinvest them in additional shares at net asset value without a sales
charge.

Dividends and distributions  may be paid in December and/or February.  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 will 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 are taxed at the rates
applicable  to  ordinary  income,  except that the  maximum  rate for  long-term
capital gains for  individuals is 28%.  Legislation has been proposed that would
have the effect of reducing the federal income tax rate on capital gains.

Shareholders may be subject to a $50 penalty under the Internal Revenue Code and
we may be required to withhold and remit to the U.S. Treasury a portion (31%) of
any redemption  proceeds  (including the value of shares  exchanged into another
Lord Abbett-sponsored fund), and of any dividend or distribution on any account,
where  the  payee   (shareholder)   failed   to   provide  a  correct   taxpayer
identification number or to make certain required certifications. 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  procedures  described  above to redeem
shares directly,  send your request to Lord Abbett  Developing Growth 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,  accom-panied 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, as our agent, prior to the close of Lord Abbett's business day, you
will receive the net asset value of the shares being redeemed 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 of the shares being purchased (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 dollar amount of the redemption proceeds.
Under certain  circumstances  and subject to prior written notice,  our Board of
Directors may authorize  redemption of all of the shares in any account in which
there are fewer than 25 shares.

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

10 PERFORMANCE

The Fund  completed its fiscal year on January 31, 1997 with net asset values of
$12.80  per share for the Class A shares and $12.75 per share for both the Class
B and Class C shares, respectively.
While  the stock  market as a whole  performed  well over the year,  the  strong
performance  that the Fund posted over the past 12 months can be  attributed  to
careful stock  selection  within the small-cap  arena.  In particular,  the Fund
benefited from its exposure to select companies in the technology,  service, and
energy sectors, as well as industrial machinery companies.

The Fund continued to focus on niche companies.  Many of these companies,  whose
expertise in specialty products or services precludes much competition,  enjoy a
large market share within their  industries.  Additionally,  niche companies are
less  vulnerable to economic or marketplace  trends.  As such,  companies in the
Fund enjoyed steady  earnings  throughout the year. The Fund seeks to temper the
volatility  inherent in the small-cap arena through  diversity.  At the close of
the fiscal  year,  the Fund  owned  over 120  companies  covering  17  different
industries.

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

LORD ABBETT


STATEMENT OF ADDITIONAL INFORMATION                                 JUNE 1, 1997


                                   LORD ABBETT
                          DEVELOPING GROWTH 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 June 1, 1997.

Lord Abbett Developing Growth Fund, Inc.  (sometimes  referred to as "we" or the
"Fund")  was  incorporated  under  Maryland  law on  August  21,  1978  and  its
predecessor  corporation was organized on July 11, 1973. Our authorized  capital
stock  consists  of three  classes (A, B and C),  $0.01 par value.  The Board of
Directors  will  allocate  these  authorized  shares of capital  stock among the
classes from time to time. All shares have equal noncumulative voting rights and
equal  rights with  respect to  dividends,  assets and  liquidation,  except for
certain  class-specific  expenses.  They are fully paid and  nonassessable  when
issued and have no preemptive or  conversion  rights.  Although no present plans
exist to do so,  further  classes  may be added in the  future.  The  Investment
Company Act of 1940,  as amended (the "Act"),  requires that where more than one
class exists,  each class must be preferred over all other classes in respect of
assets specifically allocated to such class.

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 a
contract  with a principal  underwriter  and the election of directors  from its
separate voting requirements.

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

                        Investment Objective 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 ("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  such  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)  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 change in the market  value of portfolio  securities  but will be
determined at the time of purchase or sale of such securities.

NON-FUNDAMENTAL   INVESTMENT   RESTRICTIONS.   In  addition  to  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 securities of other  investment  companies as
defined  in the Act,  except as  permitted  by  applicable  law;  (5)  invest in
securities of issuers which, with their predecessors, have a record of less than
three years of continuous operation,  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  when more than 1/2 of 1% of the  securities  of such
issuer are owned beneficially by one or more of the Fund's officers or directors
or by one or more partners of the Fund's  underwriter  or investment  adviser if
these owners in the aggregate own  beneficially  more than 5% of such securities
of such  issuer;  (7) invest in  warrants  if, at the time of  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 Funds 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 development programs,  except that the Fund may invest
in  securities  issued by  companies  that engage in oil,  gas or other  mineral
exploration or development activities;  (9) write, purchase or sell puts, calls,
straddles,  spreads or combinations  thereof,  except to the extent permitted in
the Fund's  prospectus and statement of additional  information,  as they may be
amended from time to time; or (10) buy from or sell

                                        2

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.

Although it has no current  intention to do so, the Fund may invest in financial
futures and options on financial futures.

A repurchase  agreement is the purchase and simultaneous  commitment to resell a
security at a specified time and price.  The  underlying  security is collateral
under the agreement.  As a matter of operating  policy,  we will not invest more
than 10% of the value of our assets in  repurchase  agreements  maturing in more
than seven days.

We did not invest in repurchase  agreements or lend portfolio  securities during
our last fiscal year and have no present intent to do so.

PORTFOLIO  TURNOVER  RATE.  For the fiscal  year ended  January  31,  1997,  our
portfolio turnover rate was 42.35% versus 50.12% for the prior fiscal year.

STOCK INDEX FUTURES  CONTRACTS.  The Fund believes it can reduce the  volatility
inherent in its portfolio through the use of stock index futures  contracts.  (A
stock  index  futures  contract  is an  agreement  pursuant to which two parties
agree,  one to receive and the other to pay,  on a  specified  date an amount of
cash equal to a specified  dollar amount --  established by an exchange or board
of trade -- times the difference  between the value of the index at the close of
the last trading day of the contract and the price at which the futures contract
is  originally  written.  No  consideration  is paid or received at the time the
contract is entered into,  only the good faith deposit  described  herein.) When
Lord Abbett, our investment manager, anticipates a general decline in the sector
of the stock market which includes our portfolio  assets,  we can reduce risk by
hedging  the effect of such  decline on our ability to sell assets at best price
or otherwise  hedge a decision to delay the sale of portfolio  securities.  Such
hedging would be possible if there were an established,  regularly-quoted  stock
index for equities of the  character in which we invest and if an active  public
market  were to  develop  on a stock  exchange  or board  of  trade  in  futures
contracts based on such index.

The market  value of a futures  contract is based  primarily on the value of the
underlying  index.  Changes  in  the  value  of the  index  will  cause  roughly
corresponding  changes in the market  price of the futures  contract,  except as
otherwise  described below. If a stock index is established  which is made up of
securities   whose   market   characteristics   closely   parallel   the  market
characteristics  of the securities in our portfolio,  then the market value of a
futures contract on that index should fluctuate in a way closely  resembling the
market fluctuation of our portfolio.  Thus, if we should sell futures contracts,
a decline in the market value of the portfolio  will be offset by an increase in
the value of the short  futures  position to the extent of the hedge (i.e.,  the
percentage  of the  portfolio  value  represented  by the  value of the  futures
position).  Conversely,  when we are in a strong  cash  position  (for  example,
through  substantial  sales  of our  shares)  and  wish to  invest  the  cash in
anticipation  of a rising  market,  we could  rapidly hedge against the expected
market increase by buying futures contracts to offset the cash position and thus
cushion the adverse  effect of  attempting  to buy  individual  securities  in a
rising market.

The public  markets for existing  stock index futures  contracts,  such as those
using the  Standard  & Poor's  100 Index  and 500  Index  traded on the  Chicago
Mercantile  Exchange or those using the New York Stock Exchange  Composite Index
traded on the New York Stock  Exchange  ("NYSE"),  are active and have developed
substantial  liquidity and we expect a similar market to develop for stock index
futures on a representative  group of over-the-counter  stocks. The existence of
an active market would permit us to close out our position in futures  contracts
by purchasing an equal and opposite position in the public market. Under futures
contracts  currently in use, the  purchaser  would be required to segregate in a
separate account,  as a good faith deposit,  cash or Treasury bills in an amount
set by a board of trade or exchange (currently  approximately 5% of the contract
value).  Each day during the  contract  period we would either pay or receive an
amount of cash equal to the daily  change in the total  value of the  contracts.
The amount which we may segregate upon entering into a futures  contract may not
exceed, together with the amounts on deposit under all outstanding contracts, 5%
of the value of our  total  assets,  nor may we enter  into  additional  futures
contracts if, as a result,  the aggregate  amount  committed  under all our open
futures contracts would exceed more than one-third of the value of such assets.

There are several  risks in  connection  with the use of futures  contracts as a
hedging device. One risk is the imperfect correlation between the composition of
our portfolio  securities  and the applicable  stock index.  If the value of the
futures  contract moves more than the value of the stock being hedged,  we would
experience  either a loss or a gain on the futures  contract  which would not be
completely  offset by  movements  in the value of the  securities  which are the
subject of the hedge.  Another risk is that the value of futures  contracts  may
not correlate  perfectly  with movement in the stock index due to certain market
distortions. Although we will enter into futures contracts strictly to hedge our
portfolio or cash positions,  other investors use these investment  vehicles for
other, sometimes more speculative, purposes. At times, excess speculation in the
futures market can distort the normal market  relationship  between the price of
the futures  contract and the value of the index.  If we decide to enter into or
close out our futures position during a period of such excess  speculation,  the
hedging strategy will be more or less successful, depending on the direction and
amount  of  this  distortion,  than  otherwise  would  be the  case.  Due to the
possibility  of price  distortion  in the  futures  market  and  because  of the
imperfect  correlation between movements in the stock index and movements in the
price of stock index futures  contracts,  a correct  forecast of general  market
trends by Lord Abbett may still not result in a successful hedging transaction.

It is possible  that,  when we sell  futures  contracts  to hedge our  portfolio
against a decline in the market, the market, as measured by the stock index, may
advance while the value of securities held in our portfolio may decline. If this
occurs,  we will lose  money on the  futures  contracts  and also  experience  a
decline in value in our portfolio securities. However, Lord Abbett believes that
over time the  value of a  diversified  portfolio  will tend to move in the same
direction as the market index upon which the futures contracts are based.

Where futures  contracts  are purchased to hedge against a possible  increase in
the price of stock before we are able to invest our cash position in stock in an
orderly fashion, it is possible that the market may decline instead and we would
realize a loss; if we then decide not to invest in stock at that time because of
concern as to possible  further market  decline or for other  reasons,  we would
realize a loss on the futures  contract that would be offset,  to the extent the
cash position had not been invested in stocks being hedged.

Positions in futures contracts may be closed out only on an exchange or board of
trade which provides a market for such contracts. Although we intend to purchase
or sell  futures  contracts  only  if an  active  market  has  developed  and is
continuing,  there is no assurance  that a liquid market on an exchange or board
of trade will exist for any particular  contract or at any  particular  time. In
such event, it may not be possible to close out a futures  position,  and in the
event of adverse price movements, we would continue to be required to make daily
cash payments marking our position to market.  However,  since futures contracts
would have been used to hedge portfolio securities and such securities would not
be sold until the  futures  contracts  had been  terminated,  an increase in the
price of the  securities,  if any, may partially or completely  offset losses on
the futures contract.

We may incur  additional  brokerage  commissions  through  entering into futures
contracts,  although we also can save on  commissions  by hedging  through  such
contracts  rather  than  through  buying or  selling  individual  securities  in
anticipation  of market moves.  Successful  use by us of futures  contracts will
depend upon Lord Abbett's  ability to predict  movements in the direction of the
over-the-counter   market  generally,   which  requires   different  skills  and
techniques than predicting changes in the prices of individual stocks.

To date,  we have not  entered  into any futures  contracts  and have no present
intent to do so. An established,  regularly-  quoted stock index for equities of
the character in which we invest has not yet been established.  If such an index
is established and we actually use futures contracts,  we will disclose such use
in our Prospectus.

1. Outside  directors' fees,  including  attendance fees for board and committee
meetings,  are allocated among all Lord Abbett-sponsored  funds based on the net
assets of each fund.  A portion of the fees  payable by the Fund to its  outside
directors is being deferred  under a plan that deems the deferred  amounts to be
invested  in shares of the Fund for later  distribution  to the  directors.  The
amounts of the aggregate compensation payable by the Fund as of January 31, 1997
deemed invested in Fund shares,  including  dividends  reinvested and changes in
net asset  value  applicable  to such deemed  investments,  were:  Mr.  Bigelow,
$1,892; Mr. Dixon,  $50,314; Mr. Jansing,  $51,883; Mr. MacDonald,  $17,789; Mr.
Millican,  $53,269 and Mr. Neff, $53,574. If the amounts deemed invested in Fund
shares  were  added to each  director's  actual  holdings  of Fund  shares as of
January 31, 1997, each would own, the following:  Mr. Bigelow,  148 shares;  Mr.
Dixon, 4,899 shares; Mr. Jansing, 20,760 shares; Mr. McDonald, 1,390 shares; Mr.
Millican, 7,521 shares; and Mr. Neff, 8,863 shares.

2. Each Lord  Abbett-sponsored fund has a retirement plan providing that outside
directors may receive annual retirement benefits for life equal to 100% of their
final annual retainers following  retirement at or after age 72 with at least 10
years of  service.  Each plan also  provides  for a reduced  benefit  upon early
retirement  under  certain  circumstances,  a  pre-retirement  death benefit and
actuarially reduced  joint-and-survivor spousal benefits. Such retirement plans,
and the  deferred  compensation  plans  referred to in footnote  one,  have been
amended  recently to, among other things,  enable outside  directors to elect to
convert their  prospective  benefits under the retirement  plans to equity-based
benefits under the deferred  compensation  plans (renamed the equity-based plans
and  hereinafter  referred to as such).  Five of the six outside  directors made
such an  election.  Mr.  Jansing did not.  The amounts  accrued in column 3 were
accrued by the Lord  Abbett-sponsored  funds for the twelve months ended October
31, 1996 with respect to the  equity-based  plans.  These accruals were based on
the plans as in effect before the recent  amendments  and on the fees payable to
outside  directors  of the Fund for the twelve  months  ended  October 31, 1996.
Under the recent  amendments,  the annual  retainer was increased to $50,000 and
the annual  retirement  benefits were increased from 80% to 100% of a director's
final annual  retainer.  Thus, if Mr.  Jansing were to retire at or after age 72
and the annual retainer payable by the funds were the same as it today, he would
receive annual retirement benefits of $50,000.

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

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

                                       3.
                     Investment Advisory and Other Services

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

The services  performed by Lord Abbett are described  under "Our  Management" in
the  Prospectus.  Under the Management  Agreement,  we are obligated to pay Lord
Abbett a monthly fee,  based on average daily net assets for each month,  at the
annual  rate of .75 of 1% of the  portion  of our net  assets  not in  excess of
$100,000,000  and  .50 of 1% of  such  assets  over  $100,000,000.  This  fee is
allocated  among  Class A, B and C shares  based on the  classes'  proportionate
shares of such average daily net assets.  For the fiscal years ended January 31,
1997,  1996 and 1995,  the  management  fees  paid to Lord  Abbett  amounted  to
$1,579,214, $1,098,965 and $897,585, respectively.

We pay all expenses not  expressly  assumed by Lord Abbett,  including,  without
limitation,  12b-1 expenses,  outside directors' fees and expenses,  association
membership  dues,  legal  and  auditing  fees,  taxes,   transfer  and  dividend
disbursing  agent  fees,  shareholder  servicing  costs,  expenses  relating  to
shareholder  meetings,  expenses  of  preparing,   printing  and  mailing  stock
certificates and shareholder  reports,  expenses of registering 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 security transactions.

Deloitte & Touche LLP, Two World Financial Center, New York, New York 10281, are
the  independent  accountants of the Fund and must be approved at least annually
by 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 10286, is the
Fund's  custodian.  In accordance with the  requirements of Rule 17f-5 under the
Act, 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,  with 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 from brokers
cannot be allocated to any  particular  account,  are not a substitute  for Lord
Abbett's  services but are  supplemental  to their own research  effort and when
utilized,  are subject to internal  analysis  before being  incorporated by Lord
Abbett into their investment  process.  As a practical  matter,  it would not be
possible for Lord Abbett to generate all of the information  presently  provided
by brokers.  While  receipt of research  services from  brokerage  firms has not
reduced Lord Abbett's  normal research  activities,  the expenses of Lord Abbett
could be  materially  increased  if it  attempted  to generate  such  additional
information  through its own staff and  purchased  such  equipment  and software
packages directly from the suppliers.

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

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

If other  clients of Lord Abbett buy or sell the same  security at the same time
as we do, transactions will, to the extent  practicable,  be allocated among all
participating  accounts  in  proportion  to the amount of each order and will be
executed

                                        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.

During the fiscal  years ended  January 31, 1997,  1996 and 1995,  we paid total
commissions  to  independent  dealers  of  $1,696,590,   $981,015  and  $399,634
respectively.

                             Purchases, Redemptions
                            and Shareholder Services

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.

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

As  disclosed  in the  Prospectus,  we  calculate  our net  asset  value and are
otherwise  open for business on each day that the NYSE is open for trading.  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  maximum  offering  price of our  Class A shares  on  January  31,  1997 was
computed as follows:

 Net asset value per share (net assets divided by
 shares outstanding)............................................$12.80

 Maximum offering price per share (net asset value
 divided by .9425)..............................................$13.58

The net asset  value per share for the Class B and Class C shares is  determined
in the same  manner  as for the Class A shares  (net  assets  divided  by shares
outstanding). Our Class B and Class C shares are sold at net asset value.

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

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

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

CLASS A, B AND C RULE 12B-1 PLANS. As described in the Prospectus,  the Fund has
adopted a Distribution Plan and Agreement  pursuant to Rule 12b-1 of the Act for
each of the three  Fund  Classes:  the "A Plan",  the "B Plan" and the "C 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 shares of each Class,
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.  During the last fiscal  year,  the Fund accrued or paid
through Lord Abbett to authorized  institutions  $605,347  under the A Plan, and
for the period August 1, 1996 through  January 31, 1997,  the amounts of $17,815
and $10,975, under the B and C Plans, respectively. Lord Abbett used all amounts
received  under each Plan for payments to dealers for (i)  providing  continuous
services to shareholders,  such as answering shareholder inquiries,  maintaining
records, and assisting shareholders in making redemptions, transfers, additional
purchases and exchanges and (ii) their assistance in distributing  shares of the
Fund.

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 the outstanding  voting securities of each
Class .

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

                                       10

<PAGE>

CLASS A SHARES. As stated in the Prospectus,  subject to certain  exceptions,  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,  subject to certain exceptions,  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 services 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 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 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.

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

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

With respect to Class A and Class B shares, no CDSC is payable on redemptions by
participants or beneficiaries from employer-sponsored retirement plans under the
Internal  Revenue  Code  for  benefit  payments  due  to  plan  loans,  hardship
withdrawals,  death,  retirement or  separation  from service and for returns of
excess contributions to retirement plan sponsors. With respect to Class A shares
purchased pursuant to a special  retirement wrap program,  no CDSC is payable on
redemptions  which continue as investments in another fund  participating in the
program.  With respect to Class B shares, no CDSC is payable for redemptions (i)
in connection with Systematic Withdrawal Plan and Div-Move services as described
below under those headings, (ii) in connection with mandatory distribution under
403(b)  plans  and IRAs and  (iii) in  connection  with  death of an  individual
shareholder (a natural person).  In the case of Class A and Class C shares,  the
CDSC is received by the Fund and is  intended to  reimburse  all or a portion of
the amount paid by the Fund

                                       11

<PAGE>

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 services
to the Fund (including recoupment of the commission payments made) in connection
with the  sale of  Class B shares  before  Lord  Abbett  Distributor  has had an
opportunity to realize its anticipated  reimbursement by having such a long-term
shareholder account subject to the B Plan distribution fee.

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

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

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

                                       12

<PAGE>

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  as
described  in the  Prospectus  you may 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 of Intention 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 of Intention is not completed.
The Statement of Intention is neither a binding obligation on you to buy, nor on
the Fund to sell, the full amount indicated.

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

NET ASSET VALUE PURCHASES OF CLASS A SHARES.  As stated in the  Prospectus,  our
Class A shares may be purchased at net asset value by our  directors,  employees
of Lord Abbett,  employees of our  shareholder  servicing agent and employees of
any securities  dealer having a sales agreement with Lord Abbett who consents to
such   purchases  or  by  the  director  or  custodian   under  any  pension  or
profit-sharing plan or Payroll Deduction IRA established for the benefit of such
persons  or for the  benefit  of  employees  of any  national  securities  trade
organization  to which Lord Abbett  belongs or any company with an account(s) in
excess of $10  million  managed  by Lord  Abbett  on a  private-advisory-account
basis.  For purposes of this  paragraph,  the terms  "directors" and "employees"
include a 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 ("mutual fund wrap fee program"),  (e)
by employees,  partners and owners of  unaffiliated  consultants and advisors to
Lord Abbett, Lord Abbett Distributor or Lord Abbett-sponsored  funds who consent
to such purchase if such persons

                                       13

<PAGE>

provide  service to Lord  Abbett,  Lord  Abbett  Distributor  or such funds on a
continuing basis and are familiar with such funds, (f) through  Retirement Plans
with at least 100 eligible  employees and (g) through a special  retirement wrap
program   sponsored   by  an   authorized   institution   having   one  or  more
characteristics  distinguishing  it, in the opinion of Lord Abbett  Distributor,
from a mutual  fund wrap  program.  Such  characteristics  include,  among other
things, the fact that an authorized  institution does not charge its clients any
fee of a consulting or advisory  nature that is  economically  equivalent to the
distribution  fee  under the  Class A 12b-1  Plan and the fact that the  program
relates to a participant-  directed  Retirement Plan.  Shares are offered at net
asset  value to these  investors  for the  purpose of  promoting  goodwill  with
employees  and  others  with whom Lord  Abbett  Distributor  and/or the Fund has
business relationships.

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

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

Our Board of  Directors  may  authorize  redemption  of all of the shares in any
account  in which  there are  fewer  than 25  shares.  Before  authorizing  such
redemption, the Board must determine that it is in our economic best interest or
necessary  to  reduce   disproportionately   burdensome  expenses  in  servicing
shareholder  accounts.  At least 30 days'  prior  written  notice  will be given
before any such redemption,  during which time shareholders may avoid redemption
by bringing their accounts up to the minimum set by the Board.

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
Class B shares the CDSC will be waived on  redemptions  of up to 12% per year of
the current net asset value of your account at the time the SWP is  established.
For Class B share  redemptions  of over 12% per year, the CDSC will apply to the
entire  redemption.  Therefore,  please  contact  the  Fund  for  assistance  in
minimizing the CDSC in this situation.  With respect to Class C shares, the CDSC
will be waived on and after the first  anniversary  of their  purchase.  The SWP
involves  the  planned  redemption  of shares on a periodic  basis by  receiving
either  fixed or  variable  amounts at  periodic  intervals.  Since the value of
shares  redeemed  may be more or  less  than  their  cost,  gain or loss  may be
recognized for income tax purposes on each periodic payment.  Normally,  you may
not make  regular  investments  at the same  time you are  receiving  systematic
withdrawal  payments because it is not in your interest to pay a sales charge on
new  investments  when in  effect  a  portion  of that  new  investment  is soon
withdrawn.  The minimum investment accepted while a withdrawal plan is in effect
is  $1,000.  The SWP may be  terminated  by you or by us at any time by  written
notice.

RETIREMENT  PLANS.  The Prospectus  indicates the types of retirement  plans for
which Lord Abbett provides forms and  explanations.  Lord Abbett makes available
the retirement  plan forms including  401(k) plans and custodial  agreements for
IRAs  (Individual  Retirement  Accounts,  including  Simple IRAs and  Simplified
Employee Pensions), 403(b) plans and qualified pension and profit-sharing plans.
The forms name Investors Fiduciary Trust Company as custodian and

                                       14

<PAGE>

contain  specific   information   about  the  plans  (excluding  401(k)  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 Fund  computes the average  annual  compounded  rate of total return  during
specified  periods that would equate the initial  amount  invested to the ending
redeemable value of such investment by adding one to the computed average annual
total return, raising the sum to a power equal to the number of years covered by
the  computation  and  multiplying  the result by one  thousand  dollars,  which
represents a hypothetical initial investment.  The calculation assumes deduction
of the maximum sales charge from the initial amount invested 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 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.

Using  the  computation  method  described  above,  the  Fund's  average  annual
compounded  rates of total return for the last one, five and ten fiscal  year(s)
ending  on  January  31,  1997  were as  follows:  21.00%,  14.98%  and  12.12%,
respectively  for the  Fund's  Class A  shares.  For the  period  August 1, 1996
through January 31, 1997, the total return for the Class B and Class C shares of
the Fund were 13.40% and 18.20% (not annualized), respectively.

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

                                        7.
                                      Taxes

The value of any shares  redeemed by the Fund or  otherwise  sold may be more or
less  than your tax basis in the  shares at the time the  redemption  or sale is
made.  Any  gain or loss  generally  will be  taxable  for  federal  income  tax
purposes.  Any loss realized on the sale, or redemption of Fund 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.

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

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

If the Fund purchases  shares in certain  foreign  investment  entities,  called
"PFICs" or "passive foreign  investment  companies," it may be subject to United
States federal income tax on a portion of any "excess distribution" or gain from
the disposition of such shares,  even if such income is distributed as a taxable
dividend by the Fund to its  shareholders.  Additional  charges in the nature of
interest may be imposed on either the Fund or its  shareholders  with respect to
deferred  taxes arising from such  distributions  or gains.  If the Fund were to
invest in a passive  foreign  investment  company with respect to which the Fund
elected to make a "qualified  electing fund" election,  in lieu of the foregoing
requirements,  the Fund  might be  required  to  include  in income  each year a
portion of the ordinary earnings and net capital gains of the qualified electing
fund, even if such amount were not distributed to the Fund. Proposed legislation
would revise the passive foreign  investment  company rules in various respects;
it is unclear whether and in what form such legislation might be enacted.

The Fund will be subject to a 4% 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 Fund intends to
distribute to shareholders  each year an amount adequate to avoid the imposition
of such excise tax.

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

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

                           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 seven days
before or after any Lord  Abbett-sponsored  fund or Lord Abbett-managed  account
considers a trade or trades in such  security,  from  profiting on trades of the
same  security  within  60 days and from  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 the 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 the directors and officers. Since Registrant has its
         executive  offices  in the State of New  York,  and is  qualified  as a
         foreign  corporation  doing business in such State, the persons covered
         by the  foregoing  statute  may also be  entitled to and subject to the
         limitations of the indemnification provisions of Section 721-726 of the
         New York Business Corporation Law.

         The general effect of these statutes is to protect officers,  directors
         and  employees  of  Registrant  against  legal  liability  and expenses
         incurred by reason of their positions with the Registrant. The statutes
         provide for  indemnification  for liability for proceedings not brought
         on behalf of the  corporation  and for those  brought  on behalf of the
         corporation,   and  in  each  case   place   conditions   under   which
         indemnification  will be  permitted,  including  requirements  that the
         officer,  director  or  employee  acted in good  faith.  Under  certain
         conditions,  payment of expenses in advance of final disposition may be
         permitted. The By-laws of Registrant, without

                                                         1

<PAGE>

         limiting the  authority of Registrant to indemnify any of its officers,
         employees or agents to the extent  consistent with applicable law, make
         the  indemnification  of its  directors  mandatory  subject only to the
         conditions  and  limitations  imposed by the above-  mentioned  Section
         2-418 of Maryland  law and by the  provisions  of Section  17(h) of the
         Investment  Company  Act of  1940 as  interpreted  and  required  to be
         implemented by SEC Release No. IC-11330 of September 4, 1980.

         In referring in its By-laws to, and making indemnification of directors
         subject to the conditions and limitations of, both Section 2-418 of the
         Maryland law and Section 17(h) of the  Investment  Company Act of 1940,
         Registrant intends that conditions and limitations on the extent of the
         indemnification  of  directors  imposed  by the  provisions  of  either
         Section 2-418 or Section  17(h) shall apply and that any  inconsistency
         between the two will be resolved by  applying  the  provisions  of said
         Section 17(h) if the  condition or limitation  imposed by Section 17(h)
         is the more  stringent.  In referring in its By-laws to SEC Release No.
         IC-11330 as the source for  interpretation  and  implementation of said
         Section 17(h),  Registrant  understands that it would be required under
         its By-laws to use  reasonable  and fair means in  determining  whether
         indemnification  of a  director  should be made and  undertakes  to use
         either  (1) a final  decision  on the  merits by a court or other  body
         before  whom  the   proceeding  was  brought  that  the  person  to  be
         indemnified  ("indemnitee")  was not  liable  to  Registrant  or to its
         security  holders by reason of willful  malfeasance,  bad faith,  gross
         negligence, or reckless disregard of the duties involved in the conduct
         of his office  ("disabling  conduct")  or (2) in the  absence of such a
         decision, a reasonable determination, based upon a review of the facts,
         that the indemnitee was not liable by reason of such disabling conduct,
         by (a) the vote of a majority of a quorum of directors  who are neither
         "interested  persons"  (as defined in the 1940 Act) of  Registrant  nor
         parties to the  proceeding,  or (b) an  independent  legal counsel in a
         written opinion. Also, Registrant will make advances of attorneys' fees
         or other  expenses  incurred by a director  in his defense  only if (in
         addition  to  his  undertaking  to  repay  the  advance  if he  is  not
         ultimately entitled to  indemnification)  (1) the indemnitee provides a
         security for his  undertaking,  (2) Registrant shall be insured against
         losses arising by reason of any lawful advances, or (3) a majority of a
         quorum of the non-interested,  non-party directors of Registrant, or an
         independent legal counsel in a written opinion, shall determine,  based
         on a review of readily available facts, that there is reason to believe
         that   the   indemnitee   ultimately   will  be   found   entitled   to
         indemnification.

         Insofar as  indemnification  for liability arising under the Securities
         Act of 1933 may be permitted  to  directors,  officers and  controlling
         persons of the  Registrant  pursuant to the  foregoing  provisions,  or
         otherwise,  the  Registrant has been advised that in the opinion of the
         Securities  and Exchange  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.

         In addition, Registrant maintains a directors' and officers' errors and
         omissions liability insurance policy protecting  directors and officers
         against liability for breach of duty,  negligent act, error or omission
         committed  in their  capacity  as  directors  or  officers.  The policy
         contains certain exclusions, among which is exclusion from coverage for
         active or  deliberate  dishonest or  fraudulent  acts and exclusion for
         fines or penalties imposed by law or other matters deemed uninsurable.

Item 28. BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISER

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


1.       PURPOSE.

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


<PAGE>



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






<PAGE>



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






<PAGE>



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







<PAGE>



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







<PAGE>



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

6.       MANNER OF ELECTING OPTIONAL DEFERRALS; PAYMENT
         ELECTIONS.
                  (a) NOTICE.  Each Independent Board Member who participates in
a Plan  shall  complete,  sign and file  with the  Companies  for which he is an
Independent  Board Member a Notice of Election (the  "Notice") in one or more of
the forms attached  hereto as Exhibits A, B and C. The Notice shall include,  as
appropriate:

         sections 3(a) and (b) and of any amounts deferred under section 3(c);

<PAGE>



    (iv) any beneficiary  designated  pursuant to section 9(b) and the manner of
         payment to such designated beneficiary.
                  (b) DATE OF FIRST PAYOUT OF OPTIONAL  DEFERRALS  UNDER SECTION
3(C).  With  respect  to  amounts  deferred   pursuant  to  section  3(c),  each
Independent  Board  Member  shall have the right in the Notice to elect to defer
the receipt of such deferred compensation until any one of the following events,
which such Independent Board Member shall specify in the Notice:
         (i)      the first business day of January following the
                  year in which such Independent Board Member ceases
                  to be an Independent Board Member of the
                  Companies;
    (ii)          the date such Independent  Board Member  specifically  chooses
                  (but not  earlier  than the  January 1 of the second  calendar
                  year  following  the calendar  year in which such  election is
                  made); or
   (iii)          the date on which some  specific  future event occurs which is
                  not within the Independent Board Member's control.







<PAGE>



                  (c) DATE OF FIRST  PAYOUT OF  AMOUNTS  CREDITED  AND  DEFERRED
UNDER SECTION 3(A) AND (B).  With respect to amounts  credited to an Account and
deferred under sec tions 3(a) and (b), each Independent Board Member shall defer
the  receipt of such  amounts  until any one of the  following  dates or events,
which such Independent Board Member shall specify in the Notice:
    (i)           the first business day of January following the
                  year in which such Independent Board Member ceases
                  to be an Independent Board Member of the
                  Companies;
         (ii)     the later of the first  business day of January  following the
                  year in  which  such  Independent  Board  Member  turns 65 and
                  January 1 of the second  calendar year  following the calendar
                  year in which such election is made;
    (iii)         the later of the first  business day of January  following the
                  year in which such  Independent  Board Member retires from his
                  or her  principal  occupation  and  January  1 of  the  second
                  calendar  year  following  the  calendar  year in  which  such
                  election is made; and






<PAGE>



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







<PAGE>



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

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






<PAGE>



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


<PAGE>



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




<PAGE>



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







<PAGE>



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







<PAGE>



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







<PAGE>



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







<PAGE>



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



<PAGE>



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







<PAGE>



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

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

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

New York, New York

                   Rule 12b-1 Distribution Plan and Agreement
           LORD ABBETT DEVELOPING GROWTH FUND, INC. -- CLASS A SHARES


                  RULE 12b-1  DISTRIBUTION  PLAN AND AGREEMENT  dated as of July
12, 1996 by and between LORD ABBETT  DEVELOPING  GROWTH  FUND,  INC., a Maryland
corporation  (the "Fund"),  and LORD ABBETT  DISTRIBUTOR LLC, a New York limited
liability company (the "Distributor").

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

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

                  WHEREAS,  the Plan will succeed a Rule 12b-1 Distribution Plan
and  Agreement  between  the Fund and Lord,  Abbett & Co.  ("Lord  Abbett"),  an
affiliate of the Distributor.

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

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

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

<PAGE>


                  2. The Fund also  hereby  authorizes  the  Distributor  to use
payments  received  hereunder from the Fund in order to (A) finance any activity
which is  primarily  intended  to result in the sale of Shares  and (B)  provide
continuing  information  and  investment  services to  shareholder  accounts not
serviced by Authorized Institutions receiving a service fee from the Distributor
hereunder  and otherwise to encourage  such  accounts to remain  invested in the
Shares;  PROVIDED that (I) any payments  referred to in the foregoing clause (a)
shall not exceed the  distribution  fee  permitted  to be paid at the time under
paragraph 3 of this Plan and shall be  authorized  by the Board of  Directors of
the Fund by a vote of the kind referred to in paragraph 10 of this Plan and (II)
any  payments  referred  to in clause  (b)  shall not  exceed  the  service  fee
permitted to be paid at the time under paragraph 3 of this Plan.

                  3. The Fund is authorized to pay the Distributor hereunder for
remittance to Authorized  Institutions and/or use by the Distributor pursuant to
this Plan (A) service fees and (B) distribution fees, each at an annual rate not
to exceed .25 of 1% of the average annual net asset value of Shares outstanding,
except that service  fees  payable  with  respect to Shares that were  initially
issued, or are attributable to shares that were initially issued, by the Fund or
a  predecessor  fund  prior to June 1, 1990  shall not  exceed  .15 of 1% of the
average net asset value of such Shares. The Board of Directors of the Fund shall
from time to time determine the amounts,  within the foregoing  maximum amounts,
that the Fund may pay the  Distributor  hereunder.  Any such fees  (which may be
waived by the Authorized Institutions in whole or in part) may be calculated and
paid  quarterly or more  frequently if approved by the Board of Directors of the
Fund. Such  determinations and approvals by the Board of Directors shall be made
and  given by  votes  of the kind  referred  to in  paragraph  10 of this  Plan.
Payments by holders of Shares to the Fund of contingent  deferred  reimbursement
charges  relating to  distribution  fees paid by the Fund hereunder shall reduce
the amount of  distribution  fees for purposes of the annual 0.25%  distribution
fee limit. The Distributor will monitor the payments  hereunder and shall reduce
such  payments or take such other steps as may be  necessary  to assure that (I)
the payments pursuant to this Plan shall be consistent with Article III, Section
26,  subparagraphs  (d)(2) and (5) of the Rules of Fair Practice of the National
Association  of Securities  Dealers,  Inc. with respect to investment  companies
with  asset-based  sales  charges and service fees, as the same may be in effect
from time to time and (II) the Fund shall not pay with respect to any Authorized
Institution  service fees equal to more than .25 of 1% of the average annual net
asset value of Shares sold by (or attributable to Shares or shares sold by) such
Authorized Institution and held in an account covered by an Agreement.


<PAGE>



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

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

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

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

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

                  9. This Plan may not be amended  to  increase  materially  the
amount to be spent by the Fund hereunder above the maximum  amounts  referred to
in paragraph 3 of this Plan without a shareholder  vote in compliance  with Rule
12b-1 and Rule 18f-3 under


<PAGE>



the Act as in effect at such time, and each material  amendment must be approved
by a vote of the  Board  of  Directors  of the  Fund,  including  the  vote of a
majority of the directors who are not  "interested  persons" of the Fund and who
have no direct or indirect  financial  interest in the operation of this Plan or
in any agreement  related to this Plan,  cast in person at a meeting  called for
the purpose of voting on such  amendment.  Amendments  to this Plan which do not
increase  materially  the  amount  to be spent by the Fund  hereunder  above the
maximum amounts  referred to in paragraph 3 of this Plan may be made pursuant to
paragraph 10 of this Plan.

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

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


<PAGE>


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

         IN WITNESS  WHEREOF,  each of the parties has caused this instrument to
be executed in its name and on its behalf by its duly authorized  representative
as of the date first above written.

                                 Class B Shares

         RULE 12b-1 DISTRIBUTION PLAN AND AGREEMENT dated as of July 12, 1996 by
and between LORD ABBETT  DEVELOPING  GROWTH FUND,  INC., a Maryland  Corporation
(the  "Fund"),  and LORD ABBETT  DISTRIBUTOR  LLC, a New York limited  liability
company (the "Distributor").

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

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

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

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

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

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

                                                         1

<PAGE>



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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

                                                         4

<PAGE>



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

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

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

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

 Rule 12b-1 Distribution Plan and Agreement
           Lord Abbett Developing Growth Fund, Inc. -- Class C Shares



                  RULE 12b-1  DISTRIBUTION  PLAN AND AGREEMENT  dated as of July
12, 1996 by and between LORD ABBETT  DEVELOPING  GROWTH  FUND,  INC., a Maryland
corporation  (the "Fund"),  and LORD ABBETT  DISTRIBUTOR LLC, a New York limited
liability company (the "Distributor").

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

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

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

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

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

                  2.       Subject to possible reduction as provided below in
 this paragraph 2, the Fund shall pay to the Distributor fees (I) at the time of
 sale of Shares (A) for


<PAGE>



services,  not to exceed .25 of 1% of the net asset value of the Shares sold and
(B) for  distribution,  not to exceed  .75 of 1% of the net  asset  value of the
Shares sold;  and (II) at each  quarter-end  after the first  anniversary of the
sale of Shares (A) for  services,  at an annual  rate not to exceed .25 of 1% of
the average  annual net asset value of Shares  outstanding  for one year or more
and (B) for  distribution,  at an  annual  rate not to  exceed  .75 of 1% of the
average annual net asset value of Shares  outstanding  for one year or more. For
purposes of clause (ii) above,  (A) Shares  issued  pursuant to an exchange  for
Class C shares of another  series of the Fund or another  Lord  Abbett-sponsored
fund (or for shares of a fund  acquired by the Fund) will be  credited  with the
time held from the initial  purchase of such other shares when  determining  how
long Shares mentioned in clause (ii) have been outstanding and (B) payments will
be based on Shares  outstanding  during  any such  quarter.  Sales in clause (i)
above exclude  Shares issued for  reinvested  dividends and  distributions,  and
Shares  outstanding  in clause (ii) above include  Shares issued for  reinvested
dividends and  distributions  which have been  outstanding for one year or more.
The  Board of  Directors  of the Fund  shall  from  time to time  determine  the
amounts,  within  the  foregoing  maximum  amounts,  that  the  Fund may pay the
Distributor  hereunder.  Such  determinations by the Board of Directors shall be
made by votes of the kind referred to in paragraph 10 of this Plan.  The service
fees mentioned in this  paragraph are for the purposes  mentioned in clause (ii)
of  paragraph  1 of  this  Plan  and the  distribution  fees  mentioned  in this
paragraph  are for the  purposes  mentioned in clause (i) of paragraph 1 and the
second  sentence of paragraph 3 of this Plan. The  Distributor  will monitor the
payments  hereunder  and shall reduce such  payments or take such other steps as
may be necessary to assure that (X) the payments  pursuant to this Plan shall be
consistent  with Article III,  Section 26,  subparagraphs  (d)(2) and (5) of the
Rules of Fair Practice of the National  Association of Securities Dealers,  Inc.
with respect to investment  companies with asset-based sales charges and service
fees as the same may be in effect  from time to time and (Y) the Fund  shall not
pay with respect to any Authorized  Institution  service fees equal to more than
 .25  of 1% of  the  average  annual  net  asset  value  of  Shares  sold  by (or
attributable  to  shares  sold by) such  Authorized  Institution  and held in an
account covered by an Agreement.

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








<PAGE>



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

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

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

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

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

                  9.       This Plan may not be amended to increase materially
the amount to be spent by the Fund hereunder without the vote of a majority of
its outstanding voting securities and each material amendment must be approved
by a vote of the Board of







<PAGE>



Directors of the Fund, including the vote of a majority of the directors who are
not "in  terested  persons"  of the  Fund  and who have no  direct  or  indirect
financial  interest in the operation of this Plan or in any agreement related to
this Plan,  cast in person at a meeting called for the purpose of voting on such
amendment.

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

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

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