                                PROXY STATEMENT
                                ---------------
    
       This Proxy Statement is furnished in connection with the solicitation of
proxies by and on behalf of the Board of Directors of Lord Abbett Developing
Growth Fund, Inc., a diversified open-end management investment company
incorporated under the laws of Maryland (the "Fund"), for use at an annual
meeting of shareholders of the Fund to be held at 11:00 a.m. on Wednesday, June
19, 1996 at the offices of Lord, Abbett & Co., the investment manager and
principal underwriter of the Fund ("Lord Abbett"), on the 11th floor of the
General Motors Building, 767 Fifth Avenue, New York, New York 10153, and at any
adjournments thereof.  This proxy statement and the enclosed proxy card are
first being mailed to shareholders on or about April 17, 1996.      
    
       At the close of business on March 22, 1996 (the "Record Date"), there
were issued and outstanding 18,014,402 shares of the Fund.  Only shareholders of
record at the close of business on the Record Date are entitled to notice of,
and to vote at, the annual meeting or any adjournment thereof.  Proxies will be
solicited by mail.  Additional solicitations may be made by telephone, facsimile
or personal contact by officers or employees of Lord Abbett and its affiliates.
The Fund may also request brokerage houses, custodians, nominees, and
fiduciaries who are shareholders of record to forward proxy materials to
beneficial owners.  D.F. King & Co. has been retained to assist in the
solicitation of proxies at an estimated cost of $16,000.  The cost of the
solicitation will be borne by the Fund.      

       Shareholders are entitled to one vote for each full share, and a pro-
portionate vote for each fractional share, of the Fund held as of the Record
Date.  Under Maryland law, shares owned by two or more persons (whether as joint
tenants, co-fiduciaries or otherwise) will be voted as follows, unless a written
instrument or court order providing to the contrary has been filed with the
Secretary of the Fund:  (1) if only one votes, that vote binds all; (2) if more
                         -                                           -         
than one votes, the vote of the majority binds all; and (3) if more than one
                                                         -                  
votes and the vote is evenly divided, the vote will be cast proportionately.  If
the enclosed form of proxy is properly executed and returned in time to be voted
at the meeting, the proxies named therein will vote the shares represented by
the proxy in accordance with the instructions marked thereon.  Unmarked proxies
will be voted FOR each of the items described in this Proxy Statement and any
other matters as deemed appropriate.  A proxy may be 
<PAGE>
 
revoked by the signer at any time at or before the meeting by written notice to
the Fund, by execution of a later-dated proxy or by voting in person at the
meeting.

(1)  Of the shares listed in the foregoing table, the following constitute
     "phantom" shares credited to directors under the Deferred Plan:  Mr.
     Bigelow, 65 shares; Mr. Dixon, 3,457 shares; Mr. Jansing, 3,501 shares; Mr.
     MacDonald, 1,222 shares; Mr. Millican, 3,594 shares; Mr. Neff, 3,617
     shares; and directors as a group:  15,456 shares.      

       The Board of Directors has only one standing committee, an Audit
Committee, consisting of Messrs. Bigelow, MacDonald and Millican. The functions
performed by the Audit Committee include recommendation of the selection of
independent public accountants for the Fund to the Board of Directors for
approval, review of the scope and results of audit and non-audit services, the
adequacy of internal controls and material changes in accounting principles and
practices and other matters when requested from time to time by the directors
(the "Independent Directors") who are not "interested persons" of the Fund
within the meaning of the Investment Company Act of 1940, as amended (the
"Act"). The Audit Committee held four meetings during the fiscal year ended
January 31, 1996.
    
       The Board of Directors of the Fund met twelve times during the fiscal
year ended January 31, 1996, and each director attended at least 75% of the
total number of meetings of the board and, if he was a member of the Audit
Committee, of such committee.      

       The second column of the following table sets forth the compensation
accrued by the Fund for the Independent Directors. The third and fourth columns
set forth information with respect to the retirement plan for Independent
Directors

maintained by the Fund and the other Lord Abbett-sponsored funds. The fifth
column sets forth the total compensation accrued by the Fund and such other
funds for the Independent Directors. The second, third and fourth columns give
information for the Fund's most recent fiscal year; the fifth column gives
information for the calendar year ended December 31, 1995. No director of the
Fund associated with Lord Abbett and no officer of the Fund received any
compensation from the Fund for acting as a director or officer.

</TABLE>

(1)  Independent Directors' fees, including attendance fees for board and
     committee meetings, are generally allocated among all Lord Abbett-sponsored
     funds based on net assets of each fund.  A portion of the fees payable by
     the Fund to its Independent 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 total amount accrued under the plan for
     each Independent Director since the beginning of his tenure with the Fund,
     including dividends reinvested and changes in net asset value applicable to
     such deemed investments, as of January 31, 1996, were as follows:  Mr.
     Bigelow, $682; Mr. Dixon, $39,440; Mr. Jansing, $39,873; Mr. MacDonald,
     $13,945; Mr. Millican, $40,935; and Mr. Neff, $41,206.

(2)  Each Lord Abbett-sponsored fund has a retirement plan providing that
     Independent Directors will receive annual retirement benefits for life
     equal to 80% of their final annual retainers following retirement at or
     after age 72 with at least 10 years of service. Each plan also provides for
     a reduced benefit upon early retirement under certain circumstances, a pre-
     retirement death benefit and actuarially reduced joint-and-survivor spousal
     benefits. The amounts stated in column (IV) would be payable annually under
     such retirement plans if the director were to retire at age 72 and the
     annual retainers payable by such funds were the same as they are today.
     The amounts set forth in column (III) were accrued by the Lord Abbett-

                                       5
<PAGE>
 
     sponsored funds during the fiscal year ended  January 31, 1996 with respect
     to the retirement benefits set forth in column (IV).

(3)  This column shows aggregate Independent Directors' fees, including
     attendance fees for board and committee meetings, of a nature referred to
     in the first sentence of footnote (1), accrued by the Lord Abbett-sponsored
     funds during the year ended December 31, 1995.

        Listed below are the executive officers of the Fund, other than Messrs.
Lynch, Dow and Nordberg who are listed above in the table of nominees. Each
executive officer has been associated with Lord Abbett for over five years,
except as indicated. Messrs. Allen, Carper, Cutler, Henderson, Morris and Walsh
are partners of Lord Abbett; the others listed below are employees.

Stephen I. Allen, age 42, Vice President since 1994.
    
Daniel E. Carper, age 44, Vice President since 1986.      

Kenneth B. Cutler, age 63, Vice President and Secretary since 1978.

John J. Gargana, Jr., age 64, Vice President since 1978.
    
Thomas S. Henderson, age 64, Vice President since 1979.      

Paul A. Hilstad, age 53, Vice President since 1995 (with Lord Abbett since 1995;
formerly Senior Vice President and General Counsel of American Capital
Management & Research, Inc.).

Thomas F. Konop, age 54, Vice President since 1987.

Stephen J. McGruder, age 52, Executive Vice President since 1995.

Robert G. Morris, age 51, Vice President since 1995.

Keith F. O'Connor, age 40, Treasurer since 1987.

     Pursuant to the Fund's By-Laws, the election of each director of the Fund
requires the affirmative vote of a majority of the votes cast.  If a shareholder
abstains from voting on this matter, then the shares held by such shareholder
shall be deemed present at the meeting for purposes of determining a quorum, but
shall not       

                                       6
<PAGE>
 
    
be deemed to have been voted on this matter. If a broker returns a "non-vote"
proxy, indicating a lack of authority to vote on this matter, then the shares
covered by such non-vote shall be deemed present at the meeting for purposes of
determining a quorum but shall not be deemed to have been voted on this matter. 
     

        The Board of Directors recommends that the shareholders vote FOR the
election of each of the nominees as a director of the Fund.


 2.  RATIFICATION OR REJECTION OF INDEPENDENT PUBLIC ACCOUNTANTS

     The Board of Directors has selected Deloitte & Touche LLP as the in
dependent public accountants of the Fund for the fiscal year ending January 31,
1997. The Act requires that such selection be submitted for ratification or
rejection at the next annual meeting of shareholders if such meeting be held.
Deloitte & Touche LLP (or a predecessor firm) acted as the Fund's independent
public accountants for the year ended January 31, 1996, and for a number of
years prior thereto.  Based on information in the possession of the Fund, and
information furnished by Deloitte & Touche LLP, the firm has no direct financial
interest and no material indirect financial interest in the Fund.  A
representative of Deloitte & Touche LLP is expected to attend the meeting and
will be provided with an opportunity to make a statement and answer appropriate
questions.
    
     Ratification of the selection of Deloitte & Touche LLP requires the
affirmative vote of a majority of the votes cast. If a shareholder abstains from
voting on this matter, then the shares held by such shareholder shall be deemed
present at the meeting for purposes of determining a quorum, but shall not be
deemed to have been voted on this matter.  If a broker returns a "non-vote"
proxy, indicating a lack of authority to vote on this matter, then the shares
covered by such non-vote shall be deemed present at the meeting for purposes of
determining a quorum but shall not be deemed to have been voted on this matter.
     
     The Board of Directors recommends that shareholders vote to ratify the
selection of Deloitte & Touche LLP as the Fund's independent public accountants
for the fiscal year ending January 31, 1997.

    
 3.  PROPOSAL TO AMEND THE FUNDAMENTAL INVESTMENT POLICIES AND RESTRICTIONS OF
     THE FUND      
    
     The Board of Directors has approved various amendments to the Fund's
investment policies and restrictions in order to greater uniformity
among the Lord Abbett-sponsored funds and greater flexibility in the future
management of the Funds' portfolio
     

                                       7
<PAGE>
 
    
The Fund's investment policies and restrictions designated "fundamental"
may be changed only by the vote of a "majority" (as defined in the Act) of the
Fund's voting securities. Those investment policies and restrictions designated
"non-fundamental" may be changed by the vote of the Board of Directors alone.
Therefore, the proposed amendments to the fundamental policies and restrictions
described below require shareholder approval. The Fund's current fundamental
investment policies and restrictions and its proposed fundamental and certain
non-fundamental investment policies and restrictions are set forth in Exhibit A
attached hereto.      
    
     The Fund's  investment  policies  and  restrictions  govern  generally  the
investment  activities  of the Fund and limit its  ability  to invest in certain
types of  securities or engage in certain  types of  transactions.  The proposed
changes are not  expected to affect  materially  the current  operations  of the
Fund. The proposed  fundamental  investment  policies and restrictions have been
made less  restrictive  in order to provide  greater  uniformity  among the Lord
Abbett-sponsored  funds and greater  flexibility in the future management of the
Funds'  portfolio.  The Board of Directors has no present intention of approving
actions   permitted  by  these  less   restrictive   fundamental   policies  and
restrictions.  If it were to do so, the risks of  investing in the Fund could be
increased.  No  change  is  proposed  with  respect  to  the  Fund's  investment
objective,  which is  long-term  growth of  capital  through a  diversified  and
actively managed portfolio  consisting of developing  growth companies,  many of
which are traded over the counter.     
    
     The proposed policies and restrictions restate many of the policies and
restrictions currently in effect for the Fund.  In some instances, certain
fundamental policies and restrictions have been modified or eliminated in
accordance with developments in Federal or state blue sky regulations or in the
securities markets since the inception of the Fund.  In other instances, as
illustrated in Exhibit A, certain policies and restrictions previously deemed
fundamental have been redesignated non-fundamental. By making certain policies
and restrictions non-fundamental, the board may amend a policy or restriction as
it deems appropriate and in the best interest of the Fund and its shareholders,
without incurring the costs (normally borne by the Fund and its shareholders) of
seeking a shareholder vote.  Also, certain of the proposed fundamental
investment policies and restrictions are stated in terms of "to the extent
permitted by applicable law".  Applicable law can change over time and may
become more or less restrictive as a result.  The policies and restrictions have
been drafted in this manner so that a change in law would not require the Fund
to seek a shareholder vote to amend the policy or restriction to conform to
applicable law, as revised.      

                                       8
<PAGE>
 
    
     The principal effect of the proposed amendments will be to permit the Fund
to take certain actions not now permitted to the Fund without obtaining
additional shareholder approval. The Fund either will not be permitted to, or
does not intend to, take any such action unless such action is approved by the
Board of Directors. The board does not now intend to approve any such action or
to do so in the future unless it deems such action to be an appropriate means of
seeking the Fund's investment objective in the best interests of the Fund and
its shareholders, in which case disclosure of the change would be made in the
Fund's then current prospectus or statement of additional information or both.
Such actions, none of which the board has a present intention of approving,
involve the following matters, among others: (i) short sales of securities and
                                              -
purchases of securities on margin to the extent permitted by applicable law;
(ii) borrowings from banks in amounts up to one-third of total assets (and up to
 --
an additional 5% of total assets for temporary purposes) and such short-term
credits as may be necessary for the clearance of purchases and sales of
portfolio securities; (iii) loans of portfolio securities to the extent
                       ---
permitted by law; (iv) purchases and sales of securities directly or
indirectly secured by real estate or interests therein, commodities and
                   --
commodity contracts in accordance with applicable law so long as registration
would not be required as a commodity pool operator under the Commodity Exchange
Act; (v) with respect to 25% of gross assets, purchasing securities of one
      -
issuer representing more than 5% of the gross assets of the Fund or 10% of the
voting securities of such issuer; (vi) investments of up to 15% of gross assets
                                   --
in illiquid  securities;  (vii) pledges to secure  borrowings  pledges to secure
borrowings  or as permitted by other  investment  policies and  applicable  law;
other  investment  strategies  as permitted by law;  (viii)  investments  in the
securities of other  investment  companies to the extent permitted by applicable
law; (ix) purchases and sales of puts and calls; and (x) investments of more
      --                                              -
than 5% of gross assets in securities of issuers in operation for less than
three years. See Exhibit A hereto for a detailed comparison of the Fund's
current fundamental investment policies and restrictions and its proposed
fundamental and certain non-fundamental investment policies and restrictions.
         
     Approval of the proposed amendments to the Fund's fundamental investment
policies and restrictions requires the affirmative vote of a "majority" (as
defined in the Act) of the Fund's voting securities. A "majority" vote is
defined in the Act as the vote of the holders of the lesser of: (i) 67% or more
                                                                 -
of the voting securities present or represented by proxy at the shareholders
meeting, if the holders of more than 50% of the outstanding voting securities
are present or represented by proxy, or (ii) more than 50% of the outstanding
                                         --
voting securities. The effect of an abstention or broker non-vote is the same as
a vote against this proposal.      

     If the proposed amendments are not approved by the shareholders of the
Fund, the current fundamental policies and restrictions will continue in effect.

                                       9

        The Board of Directors recommends that shareholders vote in favor of the
proposed amendments to the Fund's fundamental investment policies and
restrictions.      


 4.  NEW DISTRIBUTION PLAN AND AGREEMENT FOR THE
     CLASS A SHARES

        At a meeting of the Board of Directors of the Fund held on March 14,
1996, the directors of the Fund unanimously approved, subject to shareholder
approval, and determined to submit to the shareholders for approval, a new
Distribution Plan and Agreement pursuant to Rule 12b-1 under the Act (the
"Proposed Plan") for the existing class of Fund shares. This class of shares is
to be designated the Class A Shares -- see Item 5 below. The text of the
Proposed Plan is attached hereto as Exhibit B. The directors who approved the
Proposed Plan include all of the Independent Directors, none of whom is an
"interested person" of the Fund within the meaning of the Act or has a direct or
indirect financial interest in the operations of the Proposed Plan or in any
agreements related thereto.
    
        If approved by shareholders, the Proposed Plan will replace a
distribution plan and agreement (the "Current Plan") that was approved by
shareholders on March 14, 1990 and became effective June 1, 1990. The changes
included in the Proposed Plan, which are described below, are designed primarily
to maintain the competitive position of the Class A Shares of the Fund.      

        Under the Current Plan (except as to certain accounts for which tracking
data is not available), the Fund pays dealers through Lord Abbett (1) an annual
                                                                   -           
service fee (payable quarterly) of 0.25% of the average daily net asset value of
shares sold by dealers on or after June 1, 1990 (0.15% of the average daily net
asset value of shares sold, or attributable to shares sold, by dealers prior to
that date) and (2) a one-time 1% distribution fee, at the time of sale, on all
                -                                                             
shares sold at the $1 million level by dealers, including sales qualifying at
such level under the rights of accumulation and statement of intention
privileges described in the Fund's prospectus in effect at such time.  These
service and distribution fees provide additional incentives for dealers (a)  to
                                                                         -     
provide continuing information and investment services to their shareholder
accounts and otherwise to encourage their accounts to remain invested in the
Fund and (b) to sell shares of the Fund.
          -                             

        Under the Current Plan, holders of shares on which the 1% distribution
fee has been paid are required to pay to the Fund a contingent deferred
reimbursement charge ("CDRC") of 1% of the original cost or the then net asset
value, whichever is less, of such shares if they are redeemed out of the Lord
Abbett-sponsored family of funds on or before the end of the twenty-fourth month
after the 

                                       10
<PAGE>
 
month in which the purchase occurred. (An exception is made for certain
redemptions by tax-qualified plans under Section 401 of the Internal Revenue
Code due to plan loans, hardship withdrawals, death, retirement or separation
from service with respect to plan participants.) If the shares are exchanged
into another Lord Abbett fund and are thereafter redeemed out of the Lord Abbett
family on or before the end of such twenty-fourth month, the charge is collected
for the Fund by the other fund. The Fund collects such a charge for other Lord
Abbett-sponsored funds in a similar situation.

     Set forth below is a description of the principal changes to be effected
under the Proposed Plan:
    
     (a) Distribution Fees.  The Fund's Board of Directors will be authorized
         -----------------                                                   
under the Proposed Plan, without further shareholder vote, to increase the
amount of annual distribution fees up to 0.25% of the average annual net assets
attributable to the Class A Shares (the "Distribution Fee Ceiling") (the annual
distribution and service fees could total 0.50% of such average annual net
assets if approved by the board).  This increased spending limit is intended
primarily to permit the directors to increase the amount to be spent for
distribution to meet changing sales competition.  The directors believe it is
desirable to be able to make these changes without further shareholder approval
because additional shareholder meetings would be time-consuming and costly to
the Fund and its shareholders.  The Board of Directors will approve additional
charges under this increased authority only if a majority of the Independent
Directors conclude in their business judgment that there is a reasonable
likelihood that the increase will benefit the Fund and its shareholders.      

     The one-time 1% distribution fee, payable at the time of certain sales as
described above, is to be charged against the Distribution Fee Ceiling.  During
the Fund's last fiscal year, payments of the one-time 1% distribution fee under
the Current Plan totaled 0.01% of the Fund's average net assets.  Subject to
shareholder approval of the Proposed Plan, the Board of Directors has authorized
the Fund to continue paying this one-time distribution fee with respect to sales
of Class A Shares, subject to three changes: First, the payments will be made in
                                             -----                              
connection with sales to retirement plans with 100 or more eligible employees,
in addition to sales at the $1 million level as under the Current Plan; Second,
                                                                        ------ 
the payments will be scaled down at certain breakpoints, as follows:  1% of the
first $5 million, 0.55% of the next $5 million, 0.50% of the next $40 million
and 0.25% over $50 million of shares sold to a retirement plan or other
qualifying purchaser within a 12-month period (beginning when the first purchase
is made at net asset value); and Third, the payments will be made to
                                 -----                              
institutions and persons permitted by applicable law and/or rules to receive
such payments ("Authorized Institutions"), rather than just to dealers as is the
case under the Current Plan.

                                       11
<PAGE>
 
    
     If shareholders approve the Proposed Plan, the Board of Directors has
authorized the Fund to pay, as an additional distribution fee, a supplemental
payment to dealers who have accounts comprising a significant percentage of the
Fund's Class A Share assets and having a lower than average redemption rate and
who have a satisfactory program for the promotion of Class A Shares. Any such
payments will be 0.10% per annum of the average assets of the Fund represented
by the Class A Share accounts of qualifying dealers, and will be charged against
the Distribution Fee Ceiling. This supple mental payment is intended by the
Board of Directors to enhance the Fund's relationships with those dealers most
likely to have a significant impact on the growth of the Class A Shares.      

     (b) Service Fees.  Service fee payments, which are to be continued under
         ------------                                                        
the Proposed Plan at an annual rate of 0.25% of the average daily net asset
value of shares sold on or after June 1, 1990 (0.15% of the average daily net
asset value of shares sold, or attributable to shares sold, prior to such date),
could be made to all Authorized Institutions (institutions and persons permitted
by applicable law and/or rules to receive such payments), rather than just to
dealers as is the case under the Current Plan.
    
     (c) Use of Payments by Lord Abbett.  Lord Abbett would be permitted to use
         ------------------------------                                        
payments received under the Proposed Plan to provide continuing services to
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 to finance activities primarily
intended to result in the sale of Class A Shares would be subject to the
Distribution Fee Ceiling.      
    
     (d) CDRC.  The CDRC applicable to the Class A Shares would be substantially
         ----                                                                   
similar to that payable under the Current Plan, except that no CDRC would be
payable in connection with redemptions by retirement plans (not just those
qualified under Section 401 of the Internal Revenue Code) attributable to any
benefit payment.  In addition, no CDRC would apply if the plan sponsor requested
a redemption to correct an excess contribution in order to comply with
applicable IRS rules.  Because CDRC payments will be made directly to the Fund,
they will have the effect of reducing the amount of the distribution fees paid
by the Fund for the purpose of complying with the Distribution Fee Ceiling.  As
in the case of the specific distribution fees authorized by the Board of
Directors of the Fund, the CDRC authorized from time to time by the board for
the Class A Shares will be described in the then current prospectus of the Fund.
         
     If the supplemental payment to dealers, the revised one-time distribution
fee and the other changes described above had been in effect for the Fund's last
fiscal year, it is estimated that, in the aggregate, they would have increased
the      

                                       12
<PAGE>
 
    
ratio of expenses to average net assets of the Fund from 1.03% to
approximately 1.04%, representing a difference of 0.01%.      

     (e) Lord Abbett Distributor.  The other party to the Proposed Plan is to be
         -----------------------                                                
Lord Abbett Distributor LLC, a New York limited liability company, to be formed
as a subsidiary of Lord Abbett ("Lord Abbett Distributor"), rather than Lord
Abbett. Lord Abbett Distributor is to take on all the underwriting functions
currently performed directly by Lord Abbett.
    
     In considering whether to recommend the Proposed Plan for approval, the
board considered, among other things, the factors set forth below:      
    
     (i) Flexibility in Adapting Distribution Fees to Meet Industry-Wide
         ---------------------------------------------------------------
Changes.  During the last several years, there has been significantly increased
competition and pricing experimentation in the mutual fund industry.  As the
pace of change increases, the Board of Directors believes it will be useful to
be able to respond more quickly to marketplace pressures, and change in
appropriate cases the amount of the Class A 12b-1 distribution fees to be paid,
without unnecessarily burdening the shareholders with the costs of additional
proxy solicitations.  The directors  believe that the increased distribution
fees described above are good examples of the desirability of this flexibility.
Based on advice received from Lord Abbett, the decision by the board to approve
the payment of distribution fees in connection with sales to retirement plans
with 100 or more eligible employees will enable the Class A Shares to compete
more effectively in this growing and important market.  The 0.10% per annum
supplemental payments to dealers who meet certain criteria will permit the Fund
to enhance relationships with those dealers most likely to have a significant
impact on the growth of the Class A Shares.      

     (ii) Expanding Categories of Persons Eligible to Receive Payments. The
          ------------------------------------------------------------     
Current Plan limits payments thereunder to dealers selling Fund shares.  Since
the Current Plan was adopted, different methods of distribution, using different
entities, have developed in the industry.  The Board of Directors sees no reason
to limit arbitrarily the categories of persons eligible to receive payments
under the Proposed Plan, and believes that the availability of payments under
the plan will induce such other entities to invest in Class A Shares.
    
     (iii)     Flexibility in Distributor's Use of Payments.  Lord Abbett has
               --------------------------------------------                  
advised the Board of Directors of the Fund that allowing Lord Abbett Distributor
to retain fees received from the Fund to (i) provide continuing information and
investment services to shareholder accounts and (ii) finance, with board
approval, any activity which is primarily intended to result in the sale of
Class A Shares, will provide useful flexibility and will be in line with common
practice in the industry.      

                                       13
<PAGE>
 
     In light of the anticipated benefits to the Fund and its shareholders as a
result of adopting the Proposed Plan, and having reviewed a comparison of the
costs to the Fund of the Current Plan and the Proposed Plan, the Directors of
the Fund have concluded, in the exercise of reasonable business judgment and in
light of their fiduciary duties, that there is a reasonable likelihood that the
Proposed Plan will benefit the Fund and its shareholders.  There can, however,
be no assurance that the anticipated benefits will be realized.
    
     Payments by the Fund to dealers through Lord Abbett under the Current Plan
for the fiscal year ended January 31, 1996 were $293,388 (representing 0.18% of
the Fund's average net assets during that period).      
    
     Set forth in the table below is a summary comparison of the Fund's
expenses, on a current and pro-forma basis taking into account the increased
fees that could be paid under the Proposed Plan.  The annual operating expenses
shown in the second column are the Fund's actual expenses for the fiscal year
ended January 31, 1996. The expenses shown in the third column represent, on a
pro-forma basis, such actual expenses of the Fund adjusted to show the effect of
the maximum distribution fee the board would be authorized to approve under the
Proposed Plan. The fourth column shows such pro-forma annual operating expenses
based on the distribution fee rate the board has approved subject to approval of
the Proposed Plan by shareholders.  The example set forth below is not a
representation of past or future expenses.  Actual expenses may be greater or
less than those shown.

     throughout this Proxy Statement. Investors should be aware that long-term
     shareholders may pay, as a front-end sales charge and under both the
     Current Plan and the Proposed Plan, more than the economic equivalent of
     the maximum  front-end sales charge  permitted by certain rules
     of the National Association of Securities Dealers, Inc.      

2.   Under both the Current Plan and the Proposed Plan, redemptions of shares on
     which the Fund's Rule 12b-1 sales distribution fee has been paid are
     subject to a CDRC of 1% of the original cost or the then net asset value,
     whichever is less, of all 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, subject to
     certain exceptions described herein.

above.

        If the shareholders approve the Proposed Plan, the Proposed Plan shall,
unless terminated as described below, become effective July 12, 1996 and
continue in effect until July 12, 1997 and from year to year thereafter only so
long as 

                                       15
<PAGE>
 
such continuance is specifically approved, at least annually, by the Fund's
Board of Directors and its Independent Directors by a vote cast in person at a
meeting called for the purpose of voting on such continuance. The Proposed Plan
may be terminated at any time by a vote of a majority of the Independent
Directors or by a shareholder vote in compliance with Rule 12b-1 under the Act.
The Plan may not be amended to increase materially the amount to be spent for
distribution above the maximum amounts set forth in the Proposed Plan without a
shareholder vote in compliance with Rule 12b-1 under the Act. All material
amendments must be approved by a majority of the Independent Directors.
    
        The Proposed Plan provides that while it is in effect, the selection and
nomination of Independent Directors is committed to the discretion of the
Independent Directors then sitting on the board. This does not prevent the
involvement of others in such selection and nomination if the final decision on
any such selection or nomination is approved by a majority of the Independent
Directors.      
    
        Pursuant to Rule 12b-1 under the Act, an affirmative vote of the holders
of a "majority" (as defined in the Act) of the Fund's voting securities is
required for approval of the Proposed Plan. A "majority" vote is defined in the
Act as the vote of the holders of the lesser of: (i) 67% or more of the voting-
securities present or represented by proxy at the shareholders meeting, if the
holders of more than 50% of the outstanding voting securities are present or
represented by proxy, or (ii) more than 50% of the outstanding voting--
securities. The effect of an abstention or broker non-vote is the same as a vote
against this proposal.     

        If the Proposed Plan is not approved by the shareholders of the Fund,
the Current Plan will continue in effect according to its terms.

        The Board of Directors recommends that shareholders vote in favor of
adoption of the Proposed Plan.


  5. AMENDMENT OF THE ARTICLES OF INCORPORATION TO AUTHORIZE CLASSES AND SERIES
     OF SHARES AND TO CONFIRM THAT THE FUND MAY IMPOSE CONTINGENT DEFERRED SALES
     CHARGES IN CONNECTION WITH REDEMPTIONS

     On March 14, 1996, the Fund's Board of Directors unanimously voted to
approve an amendment to the Articles of Incorporation of the Fund to give the
Fund's Board of Directors the power to classify the Fund's shares into classes
and series, and voted to submit such amendment to the Fund's shareholders for
approval.  The full text of the amendment is attached hereto as Exhibit C.

                                       16

     The Fund's Articles of Incorporation presently designate one class of
shares of capital stock and do not authorize the Board of Directors to create
additional classes or series.  The Board of Directors believes that the Fund's
best interests will be served if the Board of Directors is able to create new
series of shares and classes of shares within a series, with each share of a
series, regardless of class, sharing pro rata (based on net asset value) in the
portfolio and income of the series and in the series' expenses, except for
differences in expenses resulting from different Rule 12b-1 plans for the
various classes and possibly other class-specific expenses.  It is expected that
implementation of such a multi-class fund structure will (i) enable investors in
                                                          -                     
the Fund to choose the distribution option that best suits their individual
situations, (ii) facilitate distribution of the Fund's shares, and (iii)
             --                                                     --- 
maintain the competitive position of the Fund in relation to other funds that
have implemented or are seeking to implement similar distribution arrangements.

     The Board of Directors has approved, subject to shareholder approval, two
classes of shares which are to share in the Fund's portfolio but are to have
different distribution arrangements.  The existing class of Fund shares, to be
designated the "Class A Shares," will continue to be offered as described in the
Fund's current prospectus, except that the Board of Directors is recommending
that shareholders approve a new Distribution Plan and Agreement pursuant to Rule
12b-1 under the Act that, if approved, will be applicable to the Class A Shares.
See  Item 4 above.

     The second class of shares, to be designated the "Class C Shares," will be
offered at net asset value without an initial sales charge, but if redeemed for
cash before the first anniversary of purchase, will be subject to a CDRC, or
contingent deferred reimbursement charge, equal to 1% of the lower of their cost
or then net asset value.  The Class C Shares are to be subject to a Rule 12b-1
plan that involves annual distribution and service fee payments for the account
of such class equal to 1% of the average net asset value of the Class C shares.
None of these charges will be allocated to the Class A Shares.

     If the proposed amendment to the Fund's Articles of Incorporation is
approved, the Board of Directors will be authorized to create and issue one or
more additional classes of shares within the existing series and to create
additional series.  Lord Abbett has advised the Board of Directors of the Fund
that it intends to propose to the board in the near future that the board
authorize the Fund to issue a third class of shares, to be designated the "Class
B Shares".  If authorized, the Class B Shares are expected to be sold without an
initial sales charge and otherwise to be similar to the Class C Shares except
that (i) they will be subject to a contingent deferred sales charge ("CDSC")
      -                                                                     
that is payable to the distributor of such shares, rather than subject to a
contingent deferred reimbursement charge payable to the Fund as is the case with
the Class C Shares, (ii) the B Share CDSC will be substantially larger than the
                     --

CDRC charged on early redemptions of Class C Shares, (iii) the B Share CDSC
                                                      ---                  
will apply over a period of time substantially longer than the 12 months
applicable to the C Share CDRC, and will scale down to zero over that longer
period, and (iv) the Class B Shares will convert automatically into Class A
             --                                                            
Shares at net asset value after a period of time.

     Shares of all classes will vote together on all matters affecting the Fund,
except for matters, such as approval of a Rule 12b-1 plan or a related service
plan, affecting only a particular class or classes.  All shares voting on a
matter will have identical voting rights.  All issued shares will be fully paid
and non-assessable, and shareholders will have no pre-emptive or other right to
subscribe to any additional shares. All shares within a series will have the
same rights and be subject to the same limitations set forth in the Articles of
Incorporation with respect to dividends, redemptions and liquidation except for
differences resulting from class-specific Rule 12b-1 plans and related service
plans and certain other class-specific expenses.

     The proposed amendment to the Fund's Articles of Incorporation will also
make clear that the Fund may impose a CDSC and other charges (which charges may
vary within and among the classes) payable upon redemption as may be established
from time to time by the Board of Directors of the Fund.  The Fund's Articles of
Incorporation currently provide that the Fund may deduct a redemption charge not
exceeding 1% of the net asset value of the shares being redeemed.  The proposed
amendment is deemed advisable in order to avoid any question as to whether the
proposed B Share CDSC referred to above, which in some instances may exceed 1%,
may be imposed in connection with the proposed issuance of the Class B Shares.
The Board of Directors has no intention of increasing the CDRC currently payable
or proposed to be payable on certain early redemptions of your Fund shares.
See Item 4 above.
    
     Approval of the proposed amendment to the Articles of Incorporation
requires an affirmative vote of  more than 50% of the outstanding shares of the
Fund.  The effect of an abstention or broker non-vote is the same as a vote
against this proposal.      

     The Board of Directors recommends that shareholders vote in favor of this
proposed amendment to the Articles of Incorporation.

  6. AMENDMENT OF THE ARTICLES OF INCORPORATION TO REDUCE THE PAR VALUE OF
     SHARES (THIS CHANGE WILL HAVE NO EFFECT ON THE VALUE OF YOUR SHARES)

          On March 14, 1996, the Fund's Board of Directors unanimously voted to
approve an amendment to the Articles of Incorporation of the Fund to reduce the
par value of shares of capital stock of the Fund from $1.00 to $0.001 per share,
and voted to submit such amendment to the Fund's shareholders for approval.
This proposed amendment is included in the text of the amendment attached as
Exhibit C.

          Under Maryland law, the par value of shares determines the amount of a
corporation's stated capital.  Stated capital has little meaning in the case of
an investment company like the Fund.  However, when the Fund increases its
authorized capital stock, it must pay a fee based on the aggregate par value of
the new shares.  This change will have no effect on the value of your shares.
The Board of Directors therefore recommends that the par value of the Fund's
shares be reduced in order to save the Fund some expense when it increases its
authorized capital stock.
    
          Approval of the proposed amendment to the Articles of Incorporation
requires an affirmative vote of a majority of the outstanding shares of the
Fund.  The effect of an abstention or broker non-vote is the same as a vote
against this proposal.      

          The Board of Directors recommends that shareholders vote in favor of
this proposed amendment to the Articles of Incorporation.


 7.  OTHER INFORMATION

          Management is not aware of any matters to come before the meeting
other than those set forth in the notice. If any such other matters do come
before the meeting, the individuals named as proxies will vote, act, and consent
with respect thereto in accordance with their best judgment.

     a.   Timeliness of Shareholder Proposals.
          ----------------------------------- 

     Any shareholder proposals to be presented for action at the Fund's next
shareholder meeting pursuant to the provisions of Rule 14a-8 under the
Securities Exchange Act of 1934, as amended, must be received at the Fund's
principal executive offices within a reasonable time in advance of the date
solicitation is made for such meeting.  The Fund does not intend to hold another
annual or special meeting of shareholders unless required to do so by the Act.

     b.   Investment Adviser and Underwriter.
          ---------------------------------- 

          Lord, Abbett & Co., 767 Fifth Avenue, New York, New York, 10153, acts
as investment adviser and principal underwriter with respect to the Fund.

     c.   Annual Report Available Upon Request.
          ------------------------------------ 
    
          The Fund will furnish, without charge, a copy of the Fund's most
recent annual report and the most recent semi-annual report succeeding the
annual report, if any, to a shareholder upon request. A shareholder may obtain
such report(s) by writing to the Fund or by calling 800-874-3733.      

     d.   Portfolio Transactions.
          ---------------------- 

          The Fund's policy is to obtain best execution on all portfolio
transactions, which means that the Fund seeks 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, the Fund may pay, as
described below, a higher commission than some brokers might charge on the same
transactions. The Fund's 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, the Fund 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
capacity 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.

          The Fund pays a commission rate that the Fund believes is appropriate
to give maximum assurance that the Fund's brokers will provide to the Fund, on a
continuing basis, the highest level of brokerage services available. While the
Fund does not always seek the lowest possible commissions on particular trades,
the Fund believes that its commission rates are in line with the rates that many
other institutions pay. The Fund's 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 the Fund and the other
accounts they manage. Such services include showing the 

                                       20
<PAGE>
 
Fund 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 the Fund's brokers also provide research services at least
some of which are useful to Lord Abbett in their overall responsibilities with
respect to the Fund 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. The Fund has 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 the
Fund's 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 the Fund, transactions will, to the extent practicable, be
allocated among all participating accounts in proportion to the amount of each
order and will be executed daily until filled so that each account shares the
average price and commission cost of each day. Other clients who direct that
their brokerage business be placed with specific brokers or who invest through
wrap accounts introduced to Lord Abbett by certain brokers may not participate
with the Fund in the buying and selling 

                                       21
<PAGE>
 
of the same securities as described above. If these clients wish to buy or sell
the same security as the Fund does, they may have their transactions executed at
times different from the Fund's transactions and thus may not receive the same
price or incur the same commission cost as the Fund does.

          For the fiscal years ended January 31, 1996, 1995 and 1994, the Fund
paid total commissions to independent broker-dealers of $250,994, $73,312 and
$87,290, respectively.

                   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 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

        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.

        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

                                       4

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.

  PROPOSED AMENDMENT TO ARTICLES OF INCORPORATION OF THE FUND AUTHORIZING THE
 BOARD OF DIRECTORS TO CREATE NEW CLASSES AND SERIES OF SHARES OF  THE CAPITAL
  STOCK OF THE FUND, CONFIRMING THAT THE FUND MAY IMPOSE CONTINGENT DEFERRED
       SALES CHARGES IN CONNECTION WITH ITS RULE 12b-1 PLANS AND REDUCING

The following text shows those provisions of the Articles of Incorporation of
the Fund that are to be amended; the text that is lined through shows deletions
and the text that is double underlined indicates additions.


                                   ARTICLE V
    
  SECTION 1.  The total number of shares which the Corporation has authority to
issue is 75,000,000 shares of capital stock of the par value of $.001 each,
having an aggregate par value of $75,000.  The Board of Directors of the
Corporation shall have full power and authority, from time to time, to classify
or reclassify any unissued shares of stock of the Corporation, including,
without limitation, the power to classify or reclassify unissued shares into
series, and to classify or reclassify a series into one or more classes of stock
that may be invested together in the common investment portfolio in which the
series is invested, by setting or changing the preferences, conversion or other
rights, voting powers, restrictions, limitations as to dividends,
qualifications, or terms or conditions of redemption of such shares of stock.
All shares of stock of a series shall represent the same interest in the
Corporation and have the same preferences, conversion or other rights, voting
powers, restrictions, limitations as to dividends, qualifications, and terms and
conditions of redemption as the other shares of stock of that series, except to
the extent that the Board of Directors provides for differing preferences,
conversion or other rights, voting powers, restrictions, limitations as to
dividends, qualifications, or terms or conditions of redemption of shares of
stock of classes of such series as determined pursuant to Articles Supplementary
filed for record with the State Department of Assessments and Taxation of
Maryland, or as otherwise determined pursuant to these Articles or by the Board
of Directors in accordance with law.  Prior to the first classification of
unissued shares of stock into additional series, all outstanding shares of stock
shall be of a single series, and prior to the first classification of a series
into additional classes, all outstanding shares of stock of such series shall be
of a single class. Notwithstanding any other provision of these Articles, upon
the first classification of unissued shares of stock into additional series, 
     
<PAGE>
 
    
the Board of Directors shall specify a legal name for the outstanding series, as
well as for the new series, in appropriate charter documents filed for record
with the State Department of Assessments and Taxation of Maryland providing for
such name change and classification, and upon the first classification of a
series into additional classes, the Board of Directors shall specify a legal
name for the outstanding class, as well as for the new class or classes, in
appropriate charter documents filed for record with the State Department of
Assessments and Taxation of Maryland providing for such name change and
classification.      
    
  SECTION 2.  A description of the relative preferences, conversion and other
rights, voting powers, restrictions, limitations as to dividends, qualifications
and terms and conditions of redemption of all series and classes of series of
shares is as follows, unless otherwise set forth in Articles Supplementary filed
for record with the State Department of Assessments and Taxation of Maryland or
otherwise determined pursuant to these Articles:      
    
          (a) Assets Belonging to Series.  All consideration received or
              --------------------------                                
              receivable by the Corporation for the issuance or sale of shares
              of a particular series, together with all assets in which such
              consideration is invested or reinvested, all income, earnings,
              profits and proceeds thereof, including any proceeds derived from
              the sale, exchange or liquidation of such assets, and any funds or
              payments derived from any reinvestment of such proceeds in
              whatever form the same may be, shall irrevocably belong to that
              series for all purposes, subject only to the rights of creditors,
              and shall be so recorded upon the books of account of the
              Corporation. Such consideration, assets, income, earnings, profits
              and proceeds, including any proceeds derived from the sale,
              exchange or liquidation of such assets, and any funds or payments
              derived from any reinvestment of such proceeds in whatever form
              the same may be, together with any unallocated items (as
              hereinafter defined) relating to that series as provided in the
              following sentence, are herein referred to as "assets belonging
              to" that series. In the event that there are any assets, income,
              earnings, profits or proceeds thereof, funds or payments which are
              not readily identifiable as belonging to any particular series
              (collectively "Unallocated Items"), the Board of Directors shall
              allocate such Unallocated Items 
     

                                       2
<PAGE>
 
    
              to and among any one or more of the series created from time to
              time in such manner and on such basis as it, in its sole
              discretion, deems fair and equitable; and any Unallocated Items so
              allocated to a particular series shall belong to that series. Each
              such allocation by the Board of Directors shall be conclusive and
              binding upon the stockholders of all series for all purposes.

          (b) Liabilities Belonging to Series.  The assets belonging to each
              -------------------------------                               
              particular series shall be charged with the liabilities of the
              Corporation in respect of that series, including any class
              thereof, and with all expenses, costs, charges and reserves
              attributable to that series, including any such class, and shall
              be so recorded upon the books of account of the Corporation. Such
              liabilities, expenses, costs, charges and reserves, together with
              any unallocated items (as hereinafter defined) relating to that
              series, including any class thereof, as provided in the following
              sentence, so charged to that series, are herein referred to as
              "liabilities belonging to" that series. In the event there are any
              unallocated liabilities, expenses, costs, charges or reserves of
              the Corporation which are not readily identifiable as belonging to
              any particular series (collectively "Unallocated Items"), the
              Board of Directors shall allocate and charge such Unallocated
              Items to and among any one or more of the series created from time
              to time in such manner and on such basis as the Board of Directors
              in its sole discretion deems fair and equitable; and any
              Unallocated Items so allocated and charged to a particular series
              shall belong to that series. Each such allocation by the Board of
              Directors shall be conclusive and binding upon the stockholders of
              all series for all purposes. To the extent determined by the Board
              of Directors, liabilities and expenses relating solely to a
              particular class (including, without limitation, distribution
              expenses under a Rule 12b-1 plan and administrative expenses under
              an administration or service agreement, plan or other arrangement,
              however designated, which may be adopted for such class) shall be
              allocated to and borne by such class and shall be appropriately
              reflected (in the      

                                       3
<PAGE>
 
    
              manner determined by the Board of Directors) in the net asset
              value, dividends and distributions and liquidation rights of the
              shares of such class.      
    
          (c) Dividends.  Dividends and distributions on shares of a particular
              ---------                                                        
              series may be paid to the holders of shares of that series at such
              times, in such manner and from such of the income and capital
              gains, accrued or realized, from the assets belonging to that
              series, after providing for actual and accrued liabilities
              belonging to that series, as the Board of Directors may determine.
              Such dividends and distributions may vary between or among classes
              of a series to reflect differing allocations of liabilities and
              expenses of such series between or among such classes to such
              extent as may be provided in or determined pursuant to Articles
              Supplementary filed for record with the State Department of
              Assessments and Taxation of Maryland or as may otherwise be
              determined by the Board of Directors.

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

          (e) Voting.  On each matter submitted to vote of the stockholders,
              ------                                                        
              each holder of a share shall be entitled to one vote for each such
              share standing in his name on the books of the Corporation
              irrespective of the series or class thereof and all shares of all
              series and classes shall vote as a single class ("Single Class
              Voting"); provided, however, that (i) as to any matter with
                                                 -
              respect to which a separate vote of any series or class is
              required by the Investment Company Act of 1940, as amended from
     

                                       4
<PAGE>
 
    
              time to time, applicable rules and regulations thereunder, or the
              Maryland General Corporation Law, such requirement as to a
              separate vote of that series or class shall apply in lieu of
              Single Class Voting as described above; (ii) in the event that the
                                                       --
              separate vote requirements referred to in (i) above apply with
              respect to one or more (but less than all) series or classes,
              then, subject to (iii) below, the shares of all other series and
                                ---
              classes shall vote as a single class; and (iii) as to any matter
                                                         ---
              which does not affect the interest of a particular series or
              class, only the holders of shares of the one or more affected
              series or classes shall be entitled to vote.      
    
          (f) Conversion.  At such times (which times may vary among shares of a
              ----------                                                        
              class) as may be determined by the Board of Directors, shares of a
              particular class of a series may be automatically converted into
              shares of another class of such series based on the relative net
              asset values of such classes at the time of conversion, subject,
              however, to any conditions of conversion that may be imposed by
              the Board of Directors.      
    
SECTION 3. Each share of the capital stock of the Corporation shall be subject
to the following provisions:      
    
          (a)  All shares of the capital stock of the Corporation now or
               hereafter authorized shall be subject to redemption and
               redeemable at the option of the stockholder, in the sense used in
               the General Laws of the State of Maryland authorizing the
               formation of corporations. Each holder of the shares of capital
               stock of the Corporation, upon request to the Corporation
               accompanied by surrender (to the Corporation, or an agent
               designated by it) of the appropriate stock certificate or
               certificates, if any, in proper form for transfer, and such other
               instruments as the Board of Directors may require, shall be
               entitled to require the Corporation to redeem all or any part of
               the shares of capital stock outstanding in the name of
               such holder on the books of the Corporation, at a redemption
               price equal to the net asset value of such shares determined as
               hereinafter set forth      

                                       5
<PAGE>
 
    
               Notwithstanding the foregoing, the Corporation may deduct from
               the proceeds otherwise due to any stockholder requiring the
               Corporation to redeem shares a redemption charge not to exceed
               one percent (1%) of such net asset value or a reimbursement
               charge, a deferred sales charge or other charge that is integral
               to the Corporation's distribution program (which charges may vary
               within and among series and classes) as may be established from
               time to time by the Board of Directors.     
    
  SECTION 4. Notwithstanding any provision of law requiring any action to be
taken or authorized by the affirmative vote of the holders of a designated
proportion greater than a majority of the shares or votes entitled to be cast,
such action shall be effective and valid if taken or authorized by the
affirmative vote of the holders of a majority of the total number of shares
outstanding and entitled to vote thereon pursuant to the provisions of these
Articles of Incorporation.      
    
  SECTION 5. No holder of stock of the Corporation shall, as such holder, have
any right to purchase or subscribe for any shares of the capital stock of the
Corporation which it may issue or sell (whether out of the number of shares now
or hereafter authorized by these Articles of Incorporation, or any amendment
thereof, or out of any shares of the capital stock of the Corporation acquired
by it after the issue thereof, or otherwise) other than such right; if any, as
the Board of Directors, in its discretion, may determine.      


                                  ARTICLE VII

                                      ***

  SECTION 1.  In furtherance and not in limitation of the power conferred by
statute and pursuant to these Articles of Incorporation, the Board of the
Directors is expressly authorized to do the following:
    
          (b) To distribute, in its discretion, for any fiscal year (in the year
              or in the next fiscal year) as ordinary dividends and as capital
              gains distributions, respectively, amounts sufficient to enable
              the Corporation as a regulated investment company to avoid any
              liability for Federal income tax in respect of such year. Any
              distribution or      

                                       6
<PAGE>
 
    
              dividend paid to stockholders from any capital
              source shall be accompanied by a written statement showing the
              source or sources of such payment.      
    
          (g) To authorize any agreement of the character described in
              subsection (e) or (f) of this Section 1 with any person,
              corporation, association, partnership or other organization,
              although one or more of the members of the Board of Directors or
              officers of the Corporation may be the other party to any such
              agreement or an officer, director, shareholder, or member of such
              other party, and no such agreement shall be invalidated or
              rendered voidable by reason of the existence of any such
              relationship. Any director of the Corporation who is also a
              director or officer of such other corporation or who is so
              interested may be counted in determining the existence of a quorum
              at any meeting of the Board of Directors which shall authorize any
              such agreement, and may vote thereat to authorize any such
              contract or transaction, with like force and effect as if he were
              not such director or officer of such other corporation or not so
              interested. Any agreement entered into pursuant to said
              subsections (e) or (f) shall be consistent with and subject to the
              requirements of  the Investment Company Act of 1940,
              as amended from time to time, applicable rules and regulations

  SECTION 3.  For the purposes referred to in these Articles of Incorporation,
the net asset value of shares of the capital stock of the Corporation of each
series and class as of any particular time (a "determination time") shall be
determined by or pursuant to the direction of the Board of Directors as follows:
         
          (a) At times when a series is not classified into multiple classes,
              the net asset value of each share of stock of a series, as of a
              determination time, shall be the quotient, carried out to not less
              than two decimal points, obtained by dividing the net value of the
              assets of the Corporation belonging to that series (determined as
              hereinafter provided) as of such determination time by the total
              number of shares then issued or issuable of that series then
              outstanding, including all shares of that series which the
              Corporation has agreed to sell for which the price has been
              determined, and excluding shares of that series which the
              Corporation has agreed to purchase or which are subject to
              redemption for which the price has been determined.      
    
              The net value of the assets of the Corporation of a series as of a
              determination time shall be determined in accordance with sound
              accounting practice by deducting from the gross value of the
              assets of the Corporation belonging to that series (determined as
              hereinafter provided), the amount of all liabilities belonging to
              that series (as such terms are defined in subsection (b) of 
              Section 2 of Article V), in each case as of such determination
              time.

              The gross value of the assets of the Corporation belonging to a
              series as of such determination time shall be an amount equal to
              all cash, receivables, the market value of all securities for
              which market quotations are readily available and the fair value
              of other assets of the Corporation belonging to that series (as
              such terms are defined in subsection (a) of Section 2 of Article
              V) at such determination time, all determined in accordance with
              sound accounting practice and giving effect to the following:     
    
                                      ***
          (b) At times when a series is classified into multiple classes, the
              net asset value of each share of stock of a class of such series
              shall be determined in accordance with subsections (a) and (c) of
              this Section 3 with appropriate adjustments to reflect differing
              allocations of liabilities and expenses of such series between or
              among such classes to such extent as may be provided in or
              determined pursuant to Articles Supplementary filed for record
              with the State Department of Assessments and Taxation of Maryland
              or as may otherwise be determined by the Board of Directors.      
    
          (c) The Board of Directors is empowered, in its discretion, to
              establish other methods for determining such net asset value
              whenever such other methods are deemed by it to be necessary or
              desirable, including, but without limiting the generality of the
              foregoing, any method deemed necessary or desirable in order to
              enable the Corporation to comply with any provision of the
              Investment Company Act of 1940 or any rule or regulation
              thereunder.
