[Letterhead of Lord Abbett Securities Trust - Lord Abbett Bond-Debenture Trust]


FROM THE CHAIRMAN OF THE BOARD
- - - - - ------------------------------


Dear Shareholder,

          Lord, Abbett & Co. is the investment manager for two funds with
substantially similar investment objectives and policies:  your Fund and Lord
Abbett Bond-Debenture Fund, Inc.  (the "Acquiring Fund"). To eliminate the
offering of substantially identical funds and to take advantage of potential
economies of scale, the Board of Trustees of your Fund has recommended that your
Fund combine with the Acquiring Fund.

          If approved and consummated, this proposed combination of your Fund
and the Acquiring Fund will be a tax-free reorganization for Federal income tax
purposes.

          You are also being asked to ratify the selection of Deloitte & Touche
LLP as your Fund's independent accountants. A shareholder vote is required on
this matter in case the proposed combination is not consummated.

          The proposal is subject to the approval of shareholders of your Fund
at a meeting to be held in New York on June 19, 1996 at 10:00 a.m.

          YOUR VOTE ON THESE ISSUES IS CRITICAL.  TO ENSURE THAT YOUR VOTE IS
COUNTED, IT IS IMPORTANT THAT YOU:

          1.  REVIEW THE ENCLOSED PROXY STATEMENT AND PROSPECTUS;

          2.  COMPLETE AND SIGN THE ENCLOSED PROXY CARD; AND

          3.  RETURN THE PROXY CARD IN THE ENCLOSED ENVELOPE AS SOON AS
              POSSIBLE.

Your prompt response will help save your Fund the expense of additional
solicitations.

          We encourage you to review the enclosed materials.  Because we believe
this combination of funds is in the best interests of shareholders, we encourage
you to vote in favor of this proposal.

                                            Sincerely,

                                            Ronald P. Lynch
                                            Chairman of the Board

                       LORD ABBETT BOND-DEBENTURE TRUST
                               767 Fifth Avenue

Notice of a Special Meeting of Shareholders
to be held on June 19, 1996                                       April 17, 1996


Notice is given hereby of a special meeting of the shareholders of Lord Abbett
Securities Trust.  The meeting will be held in the offices of Lord, Abbett &
Co., on the 11th floor of The General Motors Building, 767 Fifth Avenue, New
York, New York on June 19, 1996, at 10:00 a.m. for the following purposes and to
transact such other business as may properly come before the meeting and any
adjournments thereof.

ITEM 1.  To consider and act upon an Agreement and Plan of Reorganization
         between Lord Abbett Bond-Debenture Trust (the "Acquired Fund"), a
         series of Lord Abbett Securities Trust, and Lord Abbett Bond-Debenture
         Fund, Inc. (the "Acquiring Fund") providing for (a) the transfer of all
         of the assets of the Acquired Fund to the Acquiring Fund in exchange
         for shares of a new class of the Acquiring Fund (to be designated
         "Class C Shares") and the assumption by the Acquiring Fund of all of
         the liabilities of the Acquired Fund, (b) the distribution of such
         Class C Shares to the shareholders of the Acquired Fund and (c) the
         subsequent termination of the Acquired Fund. A vote in favor of this
         Item 1 will be deemed to be a vote to authorize the Acquired Fund, as
         the sole shareholder of Class C Shares prior to this reorganization, to
         approve a proposed distribution plan pursuant to Section 12 of the
         Investment Company Act of 1940, as amended, and Rule 12b-1 thereunder
         applicable to that class.

ITEM 2.  To ratify the selection of Deloitte & Touche LLP as the independent
         auditors of the Lord Abbett Securities Trust for the current fiscal
         year.


                                         By order of the Board of Trustees


                                         Kenneth B. Cutler
                                         Vice President and Secretary

The Board of Trustees has fixed the close of business on March 22, 1996 as the
record date for determination of shareholders of the Acquired Fund entitled to
notice of and to vote at the meeting. Shareholders are entitled to one vote for
each share held.  As of  March 22, there were ____ shares of the Acquired Fund
issued and outstanding.

            PROXY STATEMENT AND PROSPECTUS DATED MARCH       , 1996

                         ACQUISITION OF THE ASSETS OF
                 Lord Abbett Bond-Debenture Trust, a series of
                         Lord Abbett Securities Trust
                 The General Motors Building, 767 Fifth Avenue
                              New York, NY 10153
                                (800) 426-1130

                   BY AND IN EXCHANGE FOR CLASS C SHARES OF
                     Lord Abbett Bond-Debenture Fund, Inc.
                 The General Motors Building, 767 Fifth Avenue
                              New York, NY 10153
                                (800) 426-1130


          This Proxy Statement and Prospectus relates to Class C shares (the
"Class C shares") of Lord Abbett Bond-Debenture Fund, Inc. (the "Acquiring
Fund") to be issued to, and in exchange for all the assets of, Lord Abbett Bond-
Debenture Trust (the "Acquired Fund") and, together with the Acquiring Fund, the
"Funds"), a series of Lord Abbett Securities Trust (the "Trust"). In exchange
for such assets, the Acquiring Fund will also assume all of the liabilities of
the Acquired Fund. Following receipt of the Acquiring Fund Class C shares, the
Acquired Fund will be terminated and the Class C shares will be distributed to
the shareholders of the Acquired Fund. The shareholders of the Acquired Fund are
being asked to vote to approve or disapprove these proposed transactions (the
"Reorganization"), which are more fully described in this Proxy Statement and
Prospectus.

          The Acquiring Fund and the Trust are open-end diversified investment
management companies. The Acquiring Fund and the Acquired Fund have
substantially similar investment objectives. The Acquiring Fund seeks high
current income and the opportunity for capital appreciation to produce a high
total return through a professionally-managed portfolio consisting primarily of
convertible and discount debt securities, many of which are lower rated. The
Acquired Fund seeks to achieve a high total return (current income and capital
appreciation) from an actively-managed, diversified debt-security portfolio.
Under normal circumstances, the Acquired Fund invests at least 65% of its total
assets in bonds and/or debentures and seeks unusual values, particularly in
lower-rated debt securities, sometimes referred to as "junk bonds," some of
which are convertible into common stocks or have warrants to purchase common
stocks. Lord, Abbett & Co. ("Lord Abbett") serves as investment manager to both
Funds and will continue to serve as the investment manager of the Acquiring Fund
after the Reorganization.

          The Class C shares of the Acquiring Fund will be a newly-created class
of shares that will share pro-rata with the existing class of Acquiring Fund
shares (the "Class A shares") in the portfolio, income and expenses of the
Acquiring Fund, except that each class will bear the expense of its own
distribution and shareholder servicing arrangements and certain other expenses.
See " -- Shares of the Acquiring Fund." The distribution and shareholder
servicing arrangements for the Class C shares will be substantially the same as
the arrangements currently applicable to the Acquired Fund shares. The trustees
of the Trust believe that the proposed transaction will enable the shareholders
of the Acquired
<PAGE>
 
Fund to benefit from economies of scale while continuing to invest in a
portfolio of securities managed by Lord Abbett under an investment objective
substantially similar to that of the Acquired Fund. See " -- Reasons for the
Reorganization."

          This Proxy Statement and Prospectus sets forth concisely the
information about the Acquiring Fund that a shareholder of the Acquired Fund
should know before voting on the Reorganization. It should be read and retained
for future reference. Attached as Exhibit A to this Proxy Statement and
Prospectus is a copy of the Agreement and Plan of Reorganization (the "Plan")
for the Reorganization. This Proxy Statement and Prospectus is accompanied by
the Prospectus of the Acquiring Fund dated May 1, 1995 (the "Acquiring Fund
Prospectus"), which Prospectus is incorporated by reference herein. Also
incorporated herein by reference are (a) the Statement of Additional Information
dated the date hereof relating to this Proxy Statement and Prospectus, including
the Statement of Additional Information of the Trust dated December 27, 1994 and
the Statement of Additional Information of the Acquiring Fund dated May 1, 1995,
and (b) the Prospectus of the Trust dated December 27, 1994 (the "Acquired Fund
Prospectus") [a pre-effective amendment is to be filed to incorporate by
reference the Prospectus and Statement of Additional Information of Lord Abbett
Securities Trust to be dated March 1, 1996]. Such Statements of Additional
Information and the Acquired Fund Prospectus are available, upon oral or written
request, and at no charge, from the Acquiring Fund, at its above-noted telephone
number and address.

             SPECIAL MEETING OF SHAREHOLDERS OF THE ACQUIRED FUND


          This Prospectus and Proxy Statement is furnished in connection with
the solicitation of proxies by and on behalf of the Board of Trustees of the
Trust on behalf of the Acquired Fund to be used at a Special Meeting of
Shareholders of the Trust to be held at 10:00 a.m. on June 19, 1996, at the
offices of 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
Prospectus and Proxy Statement and the enclosed proxy card are first being
mailed to shareholders of the Acquired Fund on or about April 17, 1996.

          At the close of business on March 22, 1996 (the "Record Date"), there
were issued and outstanding ____ shares of the Acquired Fund. Only shareholders
of record as of the close of business on the Record Date will be entitled to
notice of, and to vote at, the meeting or any adjournment thereof. Shareholders
of the Acquired Fund are entitled to one vote for each share. Under Delaware
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 Acquired 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.

          Approval of the Plan and the Reorganization will require the
affirmative vote of a majority of the shares of the Acquired Fund voted on the
matter. One-third of the aggregate number of shares of the Acquired Fund shall
be necessary to constitute a quorum for approval of the Plan and the
Reorganization. Shares with respect to which there is an abstention or broker
non-vote shall be counted for quorum purposes and shall not be treated as
"voted" for purposes of determining whether the proposal has passed. 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. A proxy may be revoked
by the signer at any time at or before the meeting by written notice to the
Acquired Fund, by execution of a later-dated proxy or by voting in person at the
meeting. Unless revoked, all valid proxies will be voted in accordance with the
specifications thereon or, in the absence of such specifications, FOR approval
of the Plan and the Reorganization, FOR ratification of the selection of
Deloitte & Touche as the Acquired Fund's independent auditors and on any other
matters as deemed appropriate.

          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 Acquired Fund may also request brokerage
houses, custodians, nominees, and fiduciaries who are shareholders of record to
forward proxy material to the beneficial owners. D.F. King & Co. has been
retained to assist in the solicitation of proxies at an estimated cost of
$_______. The cost of the solicitation will be borne by ______________.

          In the event that sufficient votes to approve the Plan are not
received by the meeting date, the persons named as proxies may propose one or
more adjournments of the meeting to permit further solicitation of proxies. In
determining whether to adjourn the meeting, the following factors may be
considered: the percentage of votes actually cast, the percentage of negative
votes actually cast and the nature of any further solicitation and any
information to be provided to shareholders with respect to such

                                       2
<PAGE>
 
a solicitation.  Any such adjournment will require an affirmative vote of a
majority of the shares present in person or by proxy and entitled to vote at the
meeting.  The persons named as proxies will vote upon such adjournment after
consideration of the best interests of all shareholders.

          If the Plan is not approved by the shareholders of the Acquired Fund,
or if the Reorganization is not consummated for any other reason, the Acquired
Fund will continue to engage in business as a series of the Trust.

        ITEM 1. - APPROVAL OF THE AGREEMENT AND PLAN OF REORGANIZATION

                              SUMMARY OF PROPOSAL

          The following is a summary of certain information contained elsewhere
or incorporated by reference in this Proxy Statement and Prospectus and is
qualified in its entirety by reference to such information.

OVERVIEW OF PROPOSED REORGANIZATION.  The Plan provides for the transfer to the
Acquiring Fund of all of the assets of the Acquired Fund in exchange for Class C
shares and the assumption by the Acquiring Fund of all of the liabilities of the
Acquired Fund.  The Class C shares will then be distributed to the Acquired Fund
shareholders and the Acquired Fund will be terminated.  As a result of the Reor
ganization, each shareholder of the Acquired Fund will become the owner of that
number of full and fractional Class C shares having an aggregate net asset value
equal to the aggregate net asset value of their shares of the Acquired Fund, as
of the close of business on the date the Acquired Fund assets are transferred to
the Acquiring Fund.  Consummation of the Reorganization is subject to the
approval of the Acquired Fund's shareholders and other conditions, including
Acquiring Fund shareholder approval of an amendment to its Articles of
Incorporation authorizing the creation of the Class C shares.

          To avoid a need to call an Acquiring Fund shareholders' meeting after
the Reorganization, shareholders of the Acquired Fund are being asked to
authorize the Acquired Fund, as the sole Class C shareholder of the Acquiring
Fund before the Reorganization, to approve the proposed distribution plan for
the Class C shares. A vote in favor of the Reorganization will be deemed also to
be a vote to authorize the Acquired Fund to take such action.

          The trustees of the Acquired Fund believe that the proposed
Reorganization will enable the shareholders of the Acquired Fund to benefit from
economies of scale while continuing to invest in a portfolio of securities
managed by Lord Abbett under the same investment objective as that of the
Acquired Fund. See "-- Reasons for Reorganization" for additional information
about the reasons for the Reorganization.

BUSINESSES OF THE ACQUIRED AND ACQUIRING FUNDS.  The Acquired Fund is a
diversified series of the Trust, an open-end management investment company
organized as a Delaware business trust under an Agreement and Declaration of
Trust dated February 26, 1993.  The Trust offers ten series, one of which is the
Acquired Fund, each consisting of one class of shares.  The Acquired Fund
commenced investment operations on January 3, 1994.  As of December 31, 1995,
the Acquired Fund's net assets were approximately $148 million.

          The Acquiring Fund is an open-end, diversified, management investment
company organized in 1970 and reincorporated under Maryland law on January 23,
1976.  To date, the Acquiring Fund has offered only one class of shares.  As of
December 31, 1995, the Acquiring Fund's net assets were approximately $1.34
billion.

INVESTMENT OBJECTIVES AND POLICIES OF THE ACQUIRED FUND AND THE ACQUIRING FUND.
The Acquired Fund and Acquiring Fund have substantially similar investment
objectives.  The Acquiring Fund seeks

                                       5
<PAGE>
 
high current income and the opportunity for capital appreciation to produce a
high total return through a professionally-managed portfolio consisting
primarily of convertible and discount debt securities, many of which are lower
rated.  The Acquired Fund seeks to achieve a high total return (current income
and capital appreciation) from an actively-managed, diversified debt-security
portfolio.  Under normal circumstances, the Acquired Fund invests at least 65%
of its total assets in bonds and/or debentures and seeks unusual values,
particularly in lower-rated debt securities, sometimes referred to as "junk
bonds," some of which are convertible into common stocks or have warrants to
purchase common stocks.  The two Funds also have generally similar investment
policies and restrictions.  The Acquiring Fund is seeking to revise and
reclassify certain of its investment policies and restrictions in order to
provide greater flexibility in managing the investment portfolio of the
Acquiring Fund.  Most importantly, a number of the investment policies and
restrictions that are classified as fundamental for the Acquired Fund are to be
reclassified as non-fundamental for the Acquiring Fund.  See "Comparative
Information About the Acquiring Fund and the Acquired Fund -- Investment
Objectives, Policies and Restrictions."

          The portfolio of the Acquired Fund is expected to be suitable for the
Acquiring Fund, and so no significant realignment of that portfolio is expected
in connection with the Reorganization.

PURCHASES AND EXCHANGES.  Shares of the Acquired Fund are, and Class C shares
will be, available through certain authorized dealers at the public offering
price, which is the net asset value per share.  See " -- Shares of the Acquiring
Fund."  Shareholders of the Acquired Fund may now exchange their shares for
shares of the other nine series of the Trust and for the shares of Lord Abbett
U.S. Government Securities Money Market Fund, Inc.  It is expected that holders
of Class C shares will be able to exchange their shares for Class C shares of up
to 13 other funds and series managed by Lord Abbett. Each exchange represents a
sale of shares for which a shareholder may have to recognize a gain or loss
under Federal income tax provisions.

RULE 12B-1 PLAN.  The Acquired Fund has adopted a plan pursuant to Section 12(b)
of the Investment Company Act of 1940 (the "1940 Act") and Rule 12b-1 thereunder
(a "Rule 12b-1 Plan"), under which it pays service and distribution fees at the
time shares are sold not to exceed 1% of the net asset value of such shares and
at each quarter-end after the first anniversary of the sale of shares at an
annual rate not to exceed 1% of the net asset value of such shares then
outstanding.  As part of the Reorganization, the Acquiring Fund will adopt a
Rule 12b-1 Plan applicable to the Class C shares that will be substantially the
same as the Acquired Fund's Rule 12b-1 Plan, except as noted below under " --
Rule 12b-1 Plan".

DIVIDEND POLICIES AND OPTIONS.  The Acquired Fund distributes net investment
income monthly as a dividend.  It may also pay supplemental dividends and
capital gains distributions in December or January. The Acquiring Fund has a
similar dividend and distribution policy.  The shareholders of each Fund may
reinvest such dividends and distributions in additional shares at net asset
value or take such amounts in cash.

REDEMPTION PROCEDURES.  The redemption procedures of the Acquired Fund and the
Acquiring Fund are substantially the same.  See the Acquiring Fund Prospectus
under "Redemptions."

                                       6
<PAGE>
 
TAX CONSIDERATIONS.  The consummation of the Reorganization is subject to
receipt of an opinion of counsel, substantially to the effect that, among other
things, the Reorganization will not cause a gain or loss to be recognized by the
Acquired Fund or its shareholders for federal income tax purposes.  See "--
Federal Income Tax Considerations."

RISK FACTORS.  Because of the similarities in the investment objectives of the
Funds, Lord Abbett believes that the relative risks involved in investing in the
Funds can be considered similar.  However, the investment policies and
restrictions of the Acquiring Fund have been made less restrictive compared to
those of the Acquired Fund in order to provide greater flexibility in the future
management of the investment portfolio of the Acquiring Fund.  If the Acquiring
Fund were to take to any significant extent the actions permitted by these less
restrictive policies and restrictions, a result not now anticipated, the risks
of investing in the Acquiring Fund could be greater than those involved in
investing in the Acquired Fund.  See "Comparative Information About the
Acquiring Fund and the Acquired Fund -- Investment Objectives, Policies and
Restrictions" below.





THE PLAN.  On July 12, 1996, assuming the conditions referred to below are
satisfied, the Acquired Fund will transfer all its assets to the Acquiring Fund
(the date of such transfer is referred to herein as the "Closing Date") in
exchange for (i) Class C shares of the Acquiring Fund having an aggregate net
asset value equal to the aggregate value of the assets, less liabilities, of the
Acquired Fund and (ii) the assumption by the Acquiring Fund of all the
liabilities of the Acquired Fund.  The Acquired Fund will distribute as of the
Closing Date such Class C shares pro-rata to its shareholders of record,
determined as of the close of business on the Closing Date, in exchange for
their shares of the Acquired Fund.  The net asset value of Class C shares and
the value of the Acquired Fund's assets and the amount of its liabilities will
be determined as of the Closing Date in accordance with the valuation procedures
set forth in the Acquiring Fund's Articles of Incorporation (see "Purchases" in
the Acquiring Fund Prospectus). The valuation procedures used by the Acquiring
Fund are the same as those used by the Acquired Fund.

          The obligations of the Acquiring Fund and the Acquired Fund to
consummate the Reor ganization are subject to the satisfaction of certain
conditions precedent, including (a) approval and authorization of the
Reorganization by the vote of a majority of the shares of the Acquired Fund
voted on the matter if a quorum is present, (b) receipt of a favorable ruling
from the Internal Revenue Service to the effect that the issuance of various
classes of shares by the Acquiring Fund will not result in dividends or
distributions of the Acquiring Fund constituting "preferential dividends" under
the Internal Revenue Code of 1986, as amended (the "Code"), (c) a favorable
opinion of legal counsel as to the federal income tax consequences of the
proposed transaction as described below under "Federal Income Tax
Considerations", and (d) approval by the shareholders of the Acquiring Fund of
an amendment to its Articles of Incorporation authorizing the creation of
additional classes of shares.

          The foregoing summary of the Plan does not purport to be complete, and
is subject in all respects to the provisions of, and is qualified in its
entirety by reference to, the Plan, a copy of which is attached as Exhibit A.

                                       7
<PAGE>
 
REASONS FOR THE REORGANIZATION.  The Board of Trustees of the Trust and the
Board of Directors of the Acquiring Fund, including in each case a majority who
are not "interested persons" (as defined in the 1940 Act) of either Fund or of
Lord Abbett, approved the Plan and the Reorganization on March 14, 1996, and in
this connection determined that participation in the proposed Reorganization is
in the best interests of the shareholders of each of the Funds and that the
interests of existing shareholders of the Funds will not be diluted as a result
of the Reorganization.  In doing so, the boards of the two Funds considered
several factors, including that (a) the shareholders of the Acquired Fund are
expected to benefit from economies of scale as shareholders of the larger
Acquiring Fund, while continuing to invest in a portfolio of securities managed
by Lord Abbett under a substantially similar investment objective, and (b)
implementation of a multi-class fund structure for the Acquiring Fund is
expected to (i) enable investors in the Acquiring Fund to choose the
distribution option that best suits their individual situations, (ii) facilitate
distribution of the Acquiring Fund's shares, and (iii) maintain the competitive
position of the Acquiring Fund in relation to other funds that have implemented
or are seeking to implement similar distribution arrangements.

          The trustees of the Trust and the directors of the Acquiring Fund are
the same individuals.

SHARES OF THE ACQUIRING FUND.  On or before the Closing Date, the Acquiring Fund
will have two classes of shares, Class A shares (the existing class of the
Acquiring Fund) and Class C shares (to be received by the shareholders of the
Acquired Fund in the Reorganization).  Each share of the Acquiring Fund,
regardless of class, will share pro-rata (based on net asset value) in the
portfolio and income of the Acquiring Fund and in the Acquiring Fund's expenses,
except for differences in expenses resulting from different Rule 12b-1 Plans for
the classes and certain other class specific expenses.  See "Rule 12b-1 Plans"
below.  After the Reorganization, 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 contingent deferred reimbursement
charge (a "CDRC") equal to 1% of the lower of their cost or then net asset
value.  Holding periods for shares purchased prior to the Reorganization will
carry over for the purpose of determining the applicability of the CDRC.

          After the Closing Date, the Acquiring Fund may create and issue one or
more classes of shares in addition to the Class A and C shares.  Lord Abbett has
advised the Board of Directors of the Acquiring Fund that it intends to propose
to the board in the near future that the board authorize the Acquiring 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 Acquiring Fund, as is the case with the
Class C shares, (ii) the B share CDSC will be substantially larger than the 1%
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 A shares at net asset
value after a period of time.

          Shares of all classes of the Acquiring Fund will vote together on all
matters affecting the Acquiring Fund, except for matters, such as approval of a
Rule 12b-1 Plan, affecting only a particular class or classes.  All shares
voting on a matter will have identical voting rights.  All issued shares of the

                                       8
<PAGE>
 
Acquiring Fund are fully paid and non-assessable, and shareholders have no
preemptive 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
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.

RULE 12B-1 PLANS.  The Acquiring Fund is adopting a Rule 12b-1 Plan for the
Class C shares (the "Class C 12b-1 Plan") substantially the same as the plan
currently in effect for the Acquired Fund.  The Acquired Fund's plan provides
for payments to dealers through Lord Abbett of distribution and service fees (a)
at the time shares are sold, not to exceed 0.75% and 0.25%, respectively, of the
net asset value of the shares sold and (b) at the end of the quarter following
the first anniversary of the sale of shares, and quarterly thereafter, at an
annual rate not to exceed 0.75% and 0.25%, respectively, of the net asset value
of such shares, including any shares issued for reinvested dividends and
distributions after such first anniversary, so long as such shares remain
outstanding.  Lord Abbett may retain from the quarterly distribution fee, for
the payment of distribution expenses incurred directly by it, an amount not to
exceed 0.10% of the average annual net asset value of such shares outstanding.
See the Acquired Fund Prospectus under "Purchases" for additional information
concerning the Rule 12b-1 Plan of the Acquired Fund.

          There are two substantive changes in the Class C 12b-1 Plan: First,
                                                                       ----- 
payments under the plan may be made to all 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 Acquired
Fund's Rule 12b-1 Plan; and Second, the other party to the Class C 12b-1 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 itself.  Lord Abbett Distributor will take on all the underwriting
functions currently performed directly by Lord Abbett.

          The Acquiring Fund will pay smaller Rule 12b-1 distribution and
service fees in connection with the Class A shares. However, the Acquiring Fund
will sell those shares subject to an initial sales charge (see the Acquiring
Fund Prospectus under "Purchases"). The Acquired Fund does not impose, and the
Acquiring Fund will not impose with respect to the Class C shares, an initial
sales charge.

          The Class C 12b-1 Plan was approved on March 14, 1996, by the
directors of the Acquiring Fund, including a majority of the directors who are
not "interested persons" of the Acquiring Fund within the meaning of the 1940
Act and who will have no direct or indirect financial interest in the operations
of such plan or in any agreements related thereto. Prior to the Reorganization,
the Acquired Fund will purchase one Class C share, and as sole shareholder, will
approve the Class C 12b-1 Plan prior to that class being issued to the Acquired
Fund in the Reorganization. A vote in favor of the Reorganization will be deemed
also to be a vote to authorize the Acquired Fund to take such action.

FEDERAL INCOME TAX CONSIDERATIONS.  The consummation of the Reorganization is
conditioned upon the receipt of an opinion of Debevoise & Plimpton, legal
counsel to the Acquiring Fund and the Acquired Fund, substantially to the effect
that, for Federal income tax purposes:

                                       9
<PAGE>
 
          (a)  no gain or loss will be recognized by the Acquired Fund upon the
   transfer of the Acquired Fund's assets to the Acquiring Fund in exchange for
   Class C shares and the assumption by the Acquiring Fund of the liabilities of
   the Acquired Fund or upon the distribution of the Class C shares to the
   Acquired Fund's shareholders;

          (b)  no gain or loss will be recognized by the Acquiring Fund upon the
   receipt of the assets of the Acquired Fund in exchange for Class C shares and
   the assumption by the Acquiring Fund of the liabilities of the Acquired Fund;

          (c)  no gain or loss will be recognized by shareholders of the
   Acquired Fund upon the exchange of their Acquired Fund shares for Class C
   shares;

          (d)  the aggregate tax basis of the Class C shares received by any
   Acquired Fund shareholder pursuant to the Reorganization will be the same as
   the aggregate tax basis of the Acquired Fund shares held by such shareholder
   immediately prior to the Reorganization, and the holding period for the Class
   C shares to be received by any Acquired Fund shareholder will include the
   period during which the Acquired Fund shares exchanged therefor were held by
   such shareholder (provided that the Acquired Fund shares were held as capital
   assets on the date of the Reorganization); and

          (e)  the tax basis of the Acquired Fund's assets acquired by the
   Acquiring Fund will be the same as the tax basis of such assets to the
   Acquired Fund immediately prior to the Reorganization, and the holding period
   of the assets of the Acquired Fund in the hands of the Acquiring Fund will
   include the period during which those assets were held by the Acquired Fund.

       The Funds have not sought a tax ruling from the Internal Revenue Service
with respect to the tax consequences of the Reorganization, but will act in
reliance upon the opinion of counsel.  Such opinion is not binding on the
Internal Revenue Service.  Since the foregoing discussion relates only to the
general Federal income tax consequences of the Reorganization, shareholders
should also consult their tax advisors as to any state or local tax consequences
of the Reorganization to them and any special circumstances that may apply in
their individual circumstances.

EXPENSES OF THE REORGANIZATION.  Expenses of the Reorganization, including legal
and accounting expense, the costs of proxy solicitation and the preparation of
this Prospectus and Proxy Statement, will be borne by __________.  If the
Reorganization is consummated, the expenses of the Acquired Fund, to the extent
not paid prior to the Closing Date, will be assumed by the Acquiring Fund and
taken into account in determining the net assets of the Acquired Fund for the
purpose of calculating the number of Class C shares to be issued to the Acquired
Fund.

CAPITALIZATION.  The following table sets forth the capitalization of the
Acquiring Fund and the Acquired Fund as of December 31, 1995, and the pro-forma
capitalization of the Acquiring Fund as if the Reorganization had occurred on
that date:

          The foregoing table reflects a pro-forma exchange ratio of
approximately 0.5 Class C shares for each Acquired Fund share. If the
Reorganization is consummated, the actual exchange ratio may vary from this
ratio due to changes in the market value of the portfolio securities of both the
Acquiring Fund and the Acquired Fund between December 31, 1995 and the Closing
Date, and changes in the amounts of undistributed net investment income and
accrued liabilities of the Acquiring Fund and the Acquired Fund during that
period.


                       COMPARATIVE INFORMATION ABOUT THE
                     ACQUIRING FUND AND THE ACQUIRED FUND

FEES AND EXPENSES.   Both the Acquiring Fund and the Acquired Fund employ Lord
Abbett as their investment manager.  Under the management agreement between the
Acquiring Fund and Lord Abbett, the Acquiring Fund pays a monthly fee, based on
average daily net assets for each month, at the annual rate of .5 of 1% of the
Fund's first $500 million of average daily net assets and .45 of such assets
over $500 million.  For the fiscal year ended December 31, 1995, the Acquiring
Fund paid Lord Abbett a management fee at an annual rate of 0.47 of 1% of
average daily net assets.  This management agreement will continue in effect
following the Reorganization.

          Under the management agreement between the Trust and Lord Abbett, the
Trust, on behalf of the Acquired Fund, is obligated to pay a monthly fee at the
annual rate of  0.5 of 1% of average daily net assets.  For the fiscal year
ended October 31, 1995, the Acquired Fund paid Lord Abbett a management fee at
an annual rate of 0.50 of 1% of average daily net assets.

          As shown under "Fee Table" above, the Reorganization is expected to
have a favorable impact on the expense ratio experienced by the shareholders of
the Acquired Fund. As shown above under "Fee Table," the pro-forma expense ratio
for the Class C shares for the year ended October 31, 1995, calculated as if the
Reorganization had occurred at the beginning of such year, was 1.51%, compared
to an expense ratio of 1.67% for the Acquired Fund for such year.

INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS. The Acquired Fund and
Acquiring Fund have substantially similar investment objectives.  The Acquiring
Fund seeks high current income and the opportunity for capital appreciation to
produce a high total return through a professionally-managed portfolio
consisting primarily of convertible and discount debt securities, many of which
are lower rated.

                                      11
<PAGE>
 
The Acquired Fund seeks to achieve a high total return (current income and
capital appreciation) from an actively-managed, diversified debt-security
portfolio.  Under normal circumstances, the Acquired Fund invests at least 65%
of its total assets in bonds and/or debentures and seeks unusual values,
particularly in lower-rated debt securities, sometimes referred to as "junk
bonds," some of which are convertible into common stocks or have warrants to
purchase common stocks.

          The Acquired Fund and the Acquiring Fund have substantially the same
investment policies and restrictions.  However, the Acquiring Fund is seeking
approval of its shareholders to simplify and make less restrictive its
investment policies and restrictions in order to provide greater flexibility in
managing its investment portfolio.  A number of the investment policies and
restrictions that are classified as fundamental for the Acquired Fund are to be
reclassified as non-fundamental for the Acquiring Fund. In other instances,
certain fundamental restrictions of the Acquired Fund are to be modified or
eliminated in the case of the Acquiring Fund.  Fundamental investment
restrictions may not be changed without approval of the shareholders of a fund
and the costs of shareholder meetings for these purposes generally are borne by
the fund and its shareholders.  The board may amend a non-fundamental
restriction as it deems appropriate and in the best interest of the fund and its
shareholders, without incurring the costs of seeking a shareholder vote.  The
fundamental restrictions of the Acquiring Fund would permit the following
actions, among others, that are not permitted by the fundamental restrictions of
the Acquired Fund:  (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 such short-term credits as may be
necessary for the clearance of purchases and sales of portfolio securities;
(iii) purchases and sales of 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; (iv) pledges to secure
                                                 --                   
borrowings or in connection with hedging transactions and other investment
strategies; (v) investments in the securities of other investment companies; and
             -                                                                  
(vi) purchases and sales of puts and calls.  Currently, the Acquiring Fund does
 --                                                                            
not intend to take all such action, but the Board of Directors of the Fund
believes it would be desirable for the Acquiring Fund to have the ability to do
so in the future without further shareholder approval if such action was deemed
desirable as an appropriate means of seeking the Acquiring Fund's investment
objective.

          A summary comparison of the current investment policies and
restrictions of the Acquired Fund and the Acquiring Fund and of the investment
policies of the Acquiring Fund as proposed to be amended is set forth in Exhibit
B to this Proxy Statement and Prospectus.

          For a full discussion and statement of the Acquiring Fund's investment
objectives, policies and restrictions, see "Investment Objective" and "How We
Invest" in the Acquiring Fund Prospectus and "Investment Objective and Policies"
in the Acquiring Fund Statement of Additional Information. For a full discussion
and statement of the Acquired Fund investment objectives, policies and
restrictions, see "Investment Objective" and "How We Invest" in the Acquired
Fund Prospectus and "Investment Objective and Policies" in the Acquired Fund
Statement of Additional Information. The summary comparison set forth in Exhibit
B does not purport to be complete, and is subject in all respects to, and is
qualified in its entirety by reference to, such statements of such policies and
restrictions.

SHAREHOLDERS' RIGHTS.   The rights of the Acquired Fund shareholders will not
change in an adverse way as a result of the Reorganization.  After the
Reorganization, the rights of the former shareholders of the Acquired Fund
(Class C shareholders of the Acquiring Fund) will be governed by the Acquiring
Fund's Articles of Incorporation, By-Laws and applicable Maryland law rather
than by the Trust's Declaration of Trust and By-Laws and applicable Delaware
law.  The operations of the Acquiring Fund will continue to be subject to the
provisions of the 1940 Act and the rules and regulations of the Commission
thereunder.

          The current Board of Directors of the Acquiring Fund is comprised of
the same individuals as the current Board of Trustees of the Trust. The
responsibilities, powers and fiduciary duties of the directors of the Acquiring
Fund are substantially the same as those of the trustees of the Acquired Fund.
The Acquiring Fund's By-Laws provide for indemnification of the directors for
actual liabilities arising out of the directors' service in their capacity as
directors of the Acquiring Fund, subject only to the conditions and limitations
of applicable law. The Trust's Declaration of Trust provides for indem
nification of the trustees against certain liabilities and expenses, except with
respect to (i) any matter as to which any trustee has been adjudicated to have
not acted in good faith in the reasonable belief that his or her action was in
the best interest of the Acquired Fund, or (ii) any liability by reason of
willful misfeasance, bad faith, gross negligence or reckless disregard of
duties. Acquired Fund shareholders may remove a trustee by a vote of two thirds
of the eligible shares. Acquiring Fund shareholders may remove a director by the
vote of a majority of eligible shares.

          Neither the Acquired Fund nor the Acquiring Fund regularly holds
shareholder meetings. The By-laws of both Funds provide that a meeting of
shareholders will be held upon the written request of holders of at least 25% of
votes entitled to be cast.

          The foregoing is only a summary of certain rights of the shareholders
of the Acquired Fund and of the rights these shareholders will have following
the Reorganization as holders of Class C shares of the Acquiring Fund. It is not
a complete description of the Declaration of Trust of the Acquired Fund, the
Articles of Incorporation of the Acquiring Fund, the By-Laws of either Fund or
the applicable Delaware or Maryland law. Shareholders desiring additional
information about those documents and provisions of law should refer to such
Declaration of Trust, Articles of Incorporation, By-Laws and provisions.

          The Board of Trustees of the Trust recommends that shareholders vote
FOR the approval of the proposed Agreement and Plan of Reorganization and the
Reorganization.


                    ITEM 2. - RATIFICATION OR REJECTION OF
                        INDEPENDENT PUBLIC ACCOUNTANTS

          The Board of Trustees of the Trust has selected Deloitte & Touche LLP
as the independent public accountants for the Trust for the fiscal year ending
October 31, 1996. 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
Acquired Fund's independent auditors for the year ended October 31, 1995, and
for a number of years prior thereto.

                                      13
<PAGE>
 
Based on information in the possession of the Trust, and information furnished
by Deloitte & Touche LLP, the firm has no direct financial interest and no
material indirect financial interest in the Trust.  A representative of Deloitte
& Touche LLP is expected to attend the annual meeting and will be provided with
an opportunity to make a statement and answer appropriate questions.

          The Board of Trustees of the Trust recommends that shareholders vote
to ratify the selection of Deloitte & Touche LLP as the Trust's independent
public accountants for the fiscal year ending October 31, 1996.


                            ADDITIONAL INFORMATION

          To the knowledge of the Acquiring Fund and the Trust, as of March 22,
1996, no person owned of record or beneficially 5% or more of the outstanding
shares of the Acquiring Fund, the Acquired Fund or the Trust. As of December 31,
1995, the directors and officers of the Acquiring Fund, as a group, and the
trustees and officers of the Trust, as a group, owned less than 1% of the
outstanding shares of each of the Acquiring Fund, the Acquired Fund and the
Trust.

          The Acquiring Fund and the Trust (of which the Acquired Fund is a
series) are subject to the informational requirements of the Securities Exchange
Act of 1934 and in accordance therewith file reports, proxy statements and other
information with the Securities and Exchange Commission. Such reports, proxy
statements and other information filed by such entities can be inspected and
copied at the public reference facilities of the Commission at Room 1024, 450

                     AGREEMENT AND PLAN OF REORGANIZATION

          THIS AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made as
of this       day of      , 1996, by and between Lord Abbett Bond-Debenture
Fund, Inc. (the "Acquiring Fund"), a Maryland corporation, and Lord Abbett
Securities Trust (the "Trust"), a Delaware business trust, on behalf of its
series Bond-Debenture Trust (the "Acquired Fund").

          WHEREAS, this Agreement is intended to be and is adopted as a plan of

          WHEREAS, the reorganization (the "Reorganization") will consist of the
transfer of all of the assets of the Acquired Fund in exchange for Class C
shares of capital stock of the Acquiring Fund (the "Acquiring Fund Class C
Shares" and each an "Acquiring Fund Class C Share") and the assumption by the
Acquiring Fund of all of the liabilities of the Acquired Fund and the
distribution, after the Closing Date herein referred to, of Acquiring Fund Class
C Shares to the shareholders of the Acquired Fund in termination of the Acquired
Fund, all upon the terms and conditions hereinafter set forth in this Agreement;

          WHEREAS, the Trust and the Acquiring Fund are open-end, registered
investment companies of the management type;

          WHEREAS, the Acquired Fund is a series of the Trust and the Acquired

Fund is permitted to invest;

          WHEREAS, the Acquiring Fund is authorized to issue and currently has
outstanding a single class of shares (the "Acquiring Fund Class A Shares"), and
prior to the consummation of the Reorganization, will seek to amend its Articles
of Incorporation to provide for the authorization and issuance of shares of
additional classes of capital stock, including Acquiring Fund Class C Shares,
which will share pro rata with each other class in the portfolio, income and
expenses of the Acquiring Fund, except that each class will bear the expense of
its own distribution and shareholder servicing arrangements and certain other
expenses;

          WHEREAS, after the multiple class share structure is authorized by the
Acquiring Fund but before the Acquiring Fund Class C Shares are issued to the
Acquired Fund pursuant to the Reorganization, the Acquired Fund is to purchase
one Acquiring Fund Class C share and as sole shareholder approve a plan pursuant
to

<PAGE>
 
Section 12(b) of the Investment Company Act of 1940 (the "1940 Act") and Rule
12b-1 thereunder (a "Rule 12b-1 Plan") applicable to the Acquiring Fund Class C

          WHEREAS, the Board of Trustees, including a majority of the Trustees
who are not "interested persons" (as defined under the 1940 Act ), of the Trust
has determined that the Reorganization is in the best interests of the Acquired
Fund's shareholders and that the interests of the existing shareholders of the
Acquired Fund will not be diluted as a result of this transaction; and

          WHEREAS, the Board of Directors, including a majority of the Directors
who are not "interested persons" (as defined under the 1940 Act) of the
Acquiring Fund, has determined that the Reorganization is in the best interests
of the Acquiring Fund's shareholders and that the interests of the existing
shareholders of the Acquiring Fund will not be diluted as a result of this
transaction;

          NOW THEREFORE, in consideration of the premises and of the agreements
hereinafter set forth, the parties hereto agree as follows:

1.   REORGANIZATION.

          1.1.  Subject to the terms and conditions herein set forth and on the
basis of the representations and warranties contained herein, the Trust will
transfer assets of the Acquired Fund as set forth in paragraph 1.2 to the
Acquiring Fund, and the Acquiring Fund will in exchange therefor, (i) deliver to
                                                                   -            
the Acquired Fund the number of Acquiring Fund Class C Shares, including
fractional Acquiring Fund Class C Shares, determined by dividing the net value
of the Acquired Fund's assets so transferred computed in the manner and as of
the time and date set forth in paragraph 2.1, by the net asset value of one
Acquiring Fund Class A Share, computed in the manner and as of the time and date
set forth in paragraph 2.2; and (ii) to assume all of the liabilities of the
Acquired Fund.  Such transactions shall take place at the closing provided for
in paragraph 3.1 (the "Closing").

          1.2.  (a)  The assets of the Acquired Fund to be acquired by the
Acquiring Fund shall consist of all of its property, including, without
limitation, all cash, securities and dividends or interest receivables and any
deferred or prepaid expenses shown as an asset on the books of the Acquired Fund
on the closing date provided in paragraph 3.1 (the "Closing Date").

          (b)  The Acquiring Fund has a list of all of the Acquired Fund's
assets as of the date of execution of this Agreement.  The Acquired Fund has a
statement of the Acquiring Fund's investment objectives, policies and
restrictions.  The Acquired

                                       2

<PAGE>
 
Fund reserves the right to sell any of its securities but will not, without the
prior approval of the Acquiring Fund, acquire any additional securities other
than securities of the type in which the Acquiring Fund is permitted to invest.
The Acquiring Fund will, within a reasonable time prior to the Closing Date,
furnish the Acquired Fund with a list of the securities, if any, on the Acquired
Fund's list referred to in the first sentence of this paragraph which do not
conform to the Acquiring Fund's investment objectives, policies and
restrictions. In the event that the Acquired Fund holds any investments which
the Acquiring Fund may not hold, the Acquired Fund will dispose of such
securities prior to the Closing Date. In addition, if it is determined that the
portfolios of the Acquired Fund and the Acquiring Fund, when aggregated, would
contain investments exceeding certain percentage limitations imposed upon the
Acquiring Fund with respect to such investments, the Acquired Fund, if requested
by the Acquiring Fund, will dispose of and/or reinvest a sufficient amount of
such investments as may be necessary to avoid violating such limitations as of
the Closing Date.

          1.3.  As provided in paragraph 3.4, as soon after the Closing Date as
is conveniently practicable, the Acquired Fund will distribute pro rata to the
Acquired Fund's shareholders of record determined as of the close of business on
the Closing Date, the Acquiring Fund Class C Shares it receives pursuant to
paragraph 1.1. Such distribution will be accomplished by establishing Acquiring
Fund shareholder accounts in the names of each Acquired Fund shareholder,
representing the respective pro rata number of full and fractional Acquiring
Fund Class C Shares due each shareholder. All issued and outstanding shares of
the Acquired Fund will simultaneously be canceled on the books of the Acquired
Fund. The Acquiring Fund shall not issue certificates representing the Acquiring
Fund Shares in connection with such exchange.

          1.4.  Any transfer taxes payable upon issuance of Acquiring Fund Class
C Shares in a name other than the registered holder of the shares of the
Acquired Fund on the books of the Acquired Fund as of that time shall, as a
condition of such issuance and transfer, be paid by the person to whom such
Acquiring Fund Class C Shares are to be issued and transferred.

          1.5.  The Acquired Fund shall, following the Closing Date and the
making of all distributions pursuant to paragraph 1.3, be terminated by a
majority of the Trust's Trustees' executing an instrument pursuant to Section
5.4 of the Declaration and Agreement of Trust of the Trust abolishing the
Acquired Fund. Any reporting responsibility of the Trust with respect to the
Acquired Fund is and shall remain the responsibility of the Trust up to and
including the Closing Date and following the termination of the Acquired Fund.

2.   VALUATION

          2.1.  The net value of the Acquired Fund's assets to be acquired by
the Acquiring Fund hereunder shall be the value of such assets, less the
Acquired Fund's liabilities assumed by the Acquiring Fund, computed as of the
close of regular trading on New York Stock Exchange, Inc. (the "NYSE") on the
Closing Date (such time and date being hereinafter called the "Valuation Date"),
using the valuation procedures set forth in the Acquiring Fund's Articles of
Incorporation.

          2.2.  The net asset value of one Acquiring Fund Class A Share shall be
the net asset value per share computed as of the close of regular trading on the
NYSE on the Valuation Date, using the valuation procedures set forth in the
Acquiring Fund's Articles of Incorporation.

          2.3.  All computations of value shall be made by the Acquiring Fund
and the Acquired Fund in accordance with the regular practice of the Acquiring
Fund.

3.   CLOSING AND CLOSING DATE

          3.1.  The Closing Date shall be July 12, 1996, or such other date as

          (c)  The current prospectus and statement of additional information of

     all material respects to the applicable requirements of the Securities Act
     of 1933 Act, as amended (the "1933 Act"), and the 1940 Act and the rules
     and regulations of the Commission thereunder and do not (and will not)
     include any untrue statement of a material fact or omit to state any
     material fact required to be stated therein or necessary to make the

     (and will be) made, not materially misleading.


                                       5

<PAGE>
 
          (d)  The Trust is not, and the execution, delivery and performance of
     this Agreement will not result in, a material violation of its Declaration
     and Agreement of Trust or By-laws or of any agreement, instrument, contract
     or other undertaking to which the Trust is a party or by which it is bound.

          (e)  The Trust has no material contracts or other commitments which
     will be terminated with liability to the Trust on, prior to or after the
     Closing Date.

          (f)  Except as otherwise disclosed in writing to and accepted by the
     Acquiring Fund, no litigation or administrative proceeding or investigation
     before any court or governmental body is presently pending or to its
     knowledge threatened against the Trust or any of the Acquired Fund's
     properties or assets, which if adversely determined would materially and
     adversely affect the financial condition of the Acquired Fund or the
     conduct of the Acquired Fund's business.  The Trust knows of no facts which
     might form the basis of the institution of such a proceeding and is not
     party to or subject to the provisions of any order, decree or judgment of
     any court or governmental body which materially and adversely affects the
     business of the Acquired Fund or the ability of the Trust to consummate the
     transactions contemplated herein.

          (g)  True and correct copies of the Acquired Fund's (i) Statement of
                                                               -              
     Net Assets as at October 31, 1995 and (ii) Statements of Operations and
                                            --                              
     Changes in Net Assets for the 12-month period then ended, including the
     accompanying notes, have been furnished to the Acquiring Fund.  Such
     Statement of Net Assets and such Statements of Operations and Changes in
     Net Assets (and the accompanying notes) have been audited by Deloitte &
     Touche LLP, independent certified public accountants.  Such statements have
     been prepared in accordance with generally accepted accounting principles
     consistently applied, and such statements fairly reflect the financial
     condition and the operations and changes in net assets of the Acquired Fund
     as of such date and for such period, respectively.  There are no known
     contingent liabilities of the Acquired Fund as of such date required to be
     reflected or disclosed in such Statement of Net Assets or notes in
     accordance with generally accepted accounting principles that are not so
     reflected or disclosed.

          (h)  Since October 31, 1995, there has not been any material adverse
     change in the Acquired Fund's financial condition, assets, liabilities or
     business other than changes occurring in the ordinary course of business,
     or any incurrence by the Acquired Fund of indebtedness maturing more than
     one

                                       6

<PAGE>
 
     year from the date such indebtedness was incurred, except as otherwise
     disclosed to and accepted by the Acquiring Fund.

          (i)  The Trust will file the final federal and other tax returns of
     the Acquired Fund for the period ending on the Closing Date in accordance
     with the Code.  At the Closing Date, all federal and other tax returns and
     reports of the Acquired Fund required by law to have been filed prior to
     the Closing Date shall have been filed, and all federal and other taxes
     shown as due on such returns shall have been paid, or provision shall have
     been made for the payment thereof, and to the best of the Trust's
     knowledge, no such return is currently under audit and no assessment has
     been asserted with respect to such returns.

          (j)  For the most recent fiscal year of its operation, the Acquired
     Fund has met the requirements of Subchapter M of the Code for qualification
     and treatment as a regulated investment company.

          (k)  All issued and outstanding shares of the Acquired Fund are, and
     at the Closing Date will be, duly and validly issued and outstanding, fully
     paid and non-assessable.  All of the issued and outstanding shares of the
     Acquired Fund will, at the time of Closing, be held of record by the
     persons and in the amounts set forth in the records of the transfer agent
     as provided in paragraph 3.4.  The Acquired Fund does not have outstanding
     any options, warrants or other rights to subscribe for or purchase any
     shares of the Acquired Fund, nor is there outstanding any security
     convertible into any shares of the Acquired Fund.

          (l)  At the Closing Date, the Acquired Fund will have good and
     marketable title to its assets to be transferred to the Acquiring Fund
     pursuant to paragraph 1.1 and full right, power and authority to sell,
     assign, transfer and deliver such assets hereunder and, upon delivery and
     payment for such assets, the Acquiring Fund will acquire good and
     marketable title thereto, subject to no restrictions on the full transfer
     thereof, including such restrictions as might arise under the 1933 Act,
     other than as disclosed to the Acquiring Fund prior to the date hereof.

          (m)  The execution, delivery and performance of this Agreement has
     been duly authorized by all necessary action on the part of Trust's
     Trustees, and subject to the due approval of the Acquired Fund's
     shareholders, this Agreement, assuming due authorization, execution and
     delivery by the Acquiring Fund, constitutes a valid and binding obligation
     of the Trust on

     subject as to enforcement to bankruptcy, insolvency, reorganization,
     moratorium and other laws relating to or affecting creditors' rights and to
     general equity principles.  The Trust's Board of Trustees has called a
     meeting of the Trust's shareholders at which the shareholders of the
     Acquired Fund are to consider and act upon this Agreement.

          (n)  The information furnished and to be furnished by the Trust on
     behalf of the Acquired Fund for use in registration statements, proxy
     materials and other documents which may be necessary in connection with the
     transactions contemplated hereby shall be accurate and complete in all
     material respects and shall comply in all material respects with federal
     securities and other laws and regulations thereunder applicable thereto.

          (o)  The combined prospectus and proxy statement (the "N-14 prospectus
     and proxy statement") and the related statement of additional information
     included in the Registration Statement on Form N-14 of the Acquiring Fund
     (the "N-14 Registration Statement") did not on the effective date of the N-
     14 Registration Statement contain any untrue statement of a material fact
     relating to the Acquired Fund or the meeting of the Trust shareholders
     referred to therein or omit to state a material fact required to be stated
     therein or necessary to make the statements therein relating to the
     Acquired Fund or such special meeting, in light of the circumstances under
     which such statements were made, not materially misleading.

          (p)  The Acquiring Fund Class C Shares to be issued to the Acquired
     Fund hereunder are not being acquired for the purpose of making any
     distribution thereof other than in accordance with the terms of this
     Agreement.

          4.2.  The Acquiring Fund represents and warrants to the Acquired Fund
as follows:

          (a)  The Acquiring Fund is a registered investment company classified
     as a management company of the open-end type, and its registration with the

     the Acquiring Fund conform (and any prospectus or statement of additional
     information of the Acquiring Fund issued prior to the Closing Date will
     conform) in all material respects to the applicable requirements of the
     1933 Act and the 1940 Act and the rules and regulations of the Commission
     thereunder and do not (and will not) include any untrue statement of a
     material fact or omit to state any material fact required to be stated
     therein or necessary to make the statements therein, in light of the
     circumstances under which they were (or will be) made, not materially
     misleading.

          (d)  The Acquiring Fund is not, and the execution, delivery and
     performance of this Agreement  will not result in, a material violation of
     its Articles of Incorporation or By-laws or of any agreement, instrument,
     contract or other undertaking to which the Acquiring Fund is a party or by
     which it is bound.

          (e)  The Acquiring Fund has no material contracts or other commitments

     Acquired Fund, no litigation or administrative proceeding or investigation
     before any court or governmental body is presently pending or to its
     knowledge threatened against the Acquiring Fund or any of the Acquiring
     Fund's properties or assets, which, if adversely determined, would
     materially and adversely affect its financial condition or the conduct of
     its business.  The Acquiring Fund knows of no facts which might form the
     basis of the institution of such a proceeding and is not party to or
     subject to the provisions of any order, decree or judgment of any court or
     governmental body which materially and adversely affects its business or
     its ability to consummate the transactions contemplated herein.

     Changes in Net Assets for the 12-month period then ended, including the
     accompanying notes, have been furnished to the Trust.  Such Statement of

     operations and changes in net assets of the Acquiring Fund as of such date
     and for such period, respectively.  There are no known contingent
     liabilities of the Acquiring Fund as of such date required to be reflected
     or disclosed in such Statements of Net Assets or notes in accordance with
     generally accepted accounting principles that are not so reflected or
     disclosed.

     therein) did not on the effective date of the N-14 Registration Statement
     contain any untrue statement of a material fact or omit to state a material
     fact required to be stated therein or necessary to make the statements
     therein, in light of the circumstances under which such statements were

Secretary of each such party, substantially to the effect that for federal
income tax purposes:

          (a)  the acquisition by the Acquiring Fund of all of the assets of the
     Acquired Fund solely in exchange for the issuance of Acquiring Fund Class C
     Shares to the Acquired Fund and the assumption of all of the Acquired Fund
     liabilities by the Acquiring Fund, followed by the distribution by the
     Acquired Fund, in complete liquidation, of the Acquiring Fund Class C
     Shares to the Acquired Fund shareholders in exchange for their Acquired
     Fund shares, will be treated as a "reorganization" within the meaning of
     Section 368(a) of the Code, and the Acquiring Fund and the Acquired Fund
     will each be a "party to a reorganization" within the meaning of Section
     368(b) of the Code;

          (b)  no gain or loss will be recognized by the Acquiring Fund upon the
     receipt of the assets of the Acquired Fund in exchange for the Acquiring
     Fund Shares and the assumption by the Acquiring Fund of liabilities of the
     Acquired Fund;

          (c)  no gain or loss will be recognized by the Acquired Fund upon the
     transfer of the Acquired Fund's assets to the Acquiring Fund in exchange
     for the Acquiring Fund Shares and the assumption by the Acquiring Fund of
     liabilities of the Acquired Fund or upon the distribution of the Acquiring
     Fund Shares to the Acquired Fund's shareholders;

          (d)  no gain or loss will be recognized by shareholders of the
     Acquired Fund upon the exchange of their Acquired Fund shares for the
     Acquiring Fund Shares;

          (e)  the aggregate tax basis for the Acquiring Fund Shares received by
     each of the Acquired Fund's shareholders pursuant to the Reorganization
     will be the same as the aggregate tax basis of the Acquired Fund shares
     held by such shareholder immediately prior to the Reorganization, and the
     holding period of the Acquiring Fund Shares to be received by each Acquired
     Fund shareholder will include the period during which the Acquired Fund
     shares exchanged therefor were held by such shareholder (provided that the
     Acquired Fund shares were held as capital assets on the date of the
     Reorganization); and

          (f)  the tax basis of the Acquired Fund's assets acquired by the
     Acquiring Fund will be the same as the tax basis of such assets to the
     Acquired Fund immediately prior to the Reorganization, and the holding
     period of the assets of the Acquired Fund in the hands of the Acquiring
     Fund

                                      15

     will include the period during which those assets were held by the Acquired
     Fund.

          Notwithstanding anything herein to the contrary, neither the Acquiring
Fund nor the Trust may waive the conditions set forth in this paragraph 8.5.

shareholders under this Agreement to the detriment of such shareholders without

Notes to Pro-Forma Financial Statements
1.  Significant  Accounting  Policies The Lord Abbett Bond  Debenture  Fund (the
"Company")  is  registered  under  the  Investment  Company  Act  of  1940  as a
diversified,  open-end management investment company. The following is a summary
of significant  accounting policies  consistently  followed by the Company.  The
policies are in conformity with generally accepted account-ing principles.

(a) Market  value is  determined  as follows:  Securities  listed or admitted to
trading  privileges on any national  securities  exchange are valued at the last
sales price on the principal  securities  exchange on which such  securities are
traded,  or,  if there is no sale,  at the mean  between  the last bid and asked
prices  on  such  exchange,  or,  in  the  case  of  bonds  and  notes,  in  the
over-the-counter  market if, in the  judgment of the  Company's  officers,  that
market more accurately reflects the market value of bonds and notes. Securi-ties
traded only in the  over-the-counter  market are valued at the mean  between the
bid and asked prices, except that securities admitted to trad- ing on the NASDAQ
National  Market  System are valued at the last sales price if it is  determined
that  such  price  more  accurately  reflects  the  value  of  such  securities.
Securities  for which market  quotations  are not  available  are valued at fair
value under  procedures  approved by the Board of  Direc-tors,  such  procedures
require the use of estimates.

(b) It is the policy of the  Company to meet the  requirements  of the  Internal
Revenue Code applicable to regulated  investment companies and to distribute all
of its taxable income in taxable distributions. Therefore, no federal income tax
provision is required.

(c) Security  transactions are accounted for on the date that the securities are
purchased  or sold  (trade  date).  Interest  income is  recorded on the accrual
basis.  Dividend income and  distributions  to shareholders  are recorded on the
ex-dividend  date.  The Company has elected not to amortize the premiums on U.S.
Government bonds,  which is consistent with the treatment for federal income tax
purposes.

(d) A portion of the  proceeds  from sales and costs of  repurchases  of capital
shares,  equivalent to the amount of distributable  net investment income on the
date of the  transaction,  is  credited  or  charged  to  undistributed  income.
Undistributed  net  investment  income per share thus is  unaffected by sales or
repurchases of shares.

(e) The  preparation  of  financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

2. Investment Grades

Investment-grade  corporate bonds consist of securities  rated within one of the
four highest  ratings  determined  either by Moody's  Investors  Service Inc. or
Standard & Poor's Corporation. Lower rated straight debt consists of se-curities
rated lower than the four highest ratings or that have no rating.

3. Repurchase Agreements

The  Company  may  enter  into  repurchase  agreements  with  certain  banks and
broker/dealers whereby the Company, through its custodian,  receives delivery of
the underlying securities,  the amount of which at the time of purchase and each
subsequent  business day is required to be  maintained  at such a level that the
market  value,  depending on the maturity of the  repurchase  agreement  and the
underlying collateral, is equal to at least 100% of the resale price.

4. Distributions

Dividends  from net  investment  income are declared  monthly and paid  monthly.
Taxable net  realized  gains from  security  transactions,  if any,  are usually
declared in December of the current year or January of the succeeding  year. The
company had a capital loss carryforward as of December 31, 1995 of approximately
$120,000,000 of which $20,000,000  expires in 1996,  $5,000,000 expires in 1997,
$28,000,000 expires in 1998,  $17,000,000 expires in 1999, $1,000,000 expires in
2002 and $49,000,000 expires in 2003. Accordingly,  no capital gain distribution
is expected  to be paid to  shareholders  until net gains have been  realized in
excess of such amounts.

5. Agreements

The Company has a management  agreement with Lord, Abbett & Co. for the services
performed  and  expenses  assumed by Lord,  Abbett & Co., the Company paid a fee
based on average  daily net assets at the following  annual rates:  0.50% on the
first $500 million and 0.45% on the assets over $500 million.

For the Class A shares the Company has a Rule 12b-1 Plan  providing  for (a) the
payment of a service  fee to dealers at the annual  rate of .15% of the  average
daily net asset value of the  Company's  shares sold by dealers prior to June 1,
1990 and .25% of the  average  daily net asset  value of such  shares sold on or
after that date and (b) a one-time 1% distribution  fee, at the time of sale, on
such shares sold at net asset value of $1 million or more.

Pursuant to Rule 12b-1, for Class C shares,  the Company will pay, (1) a service
fee and a distribution  fee, at the time shares are sold, not to exceed .25% and
 .75%, respectively, of the net asset value of such shares and

(2) at each quarter-end  after the first anniversary of the sale of such shares,
fees for services and  distribution at annual rates not to exceed .25% and .75%,
respectively,  of the  average  annual net asset  value of shares  oustand-  ing
(payments with respect to shares not  outstanding  during the full quarter to be
prorated).  The fees  will be paid to Lord  Abbett  Distributor  llc,  which may
retain from the quarterly distribution fee, for payment of distribution expenses
incurred  directly by it, an amount not to exceed .10% of the average annual net
asset value of such shares outstanding.



                                    PART C

ITEM 15.  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 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

                                      C-1
<PAGE>
 
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.

called the "Articles"), as heretofore amended, are hereby further amended by:

          (a)  Striking out paragraph A of ARTICLE V and inserting in lieu
     thereof:

               "A.  The total number of shares which the Corporation has
          authority to issue is 300,000,000 shares of capital stock of the par
          value of $.001 each, having an aggregate par value of $300,000.  The
          amount of authorized stock of the Corporation may be increased or
          decreased by the affirmative vote of the holders of a majority of the
          stock of the Corporation entitled to vote.  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, as
<PAGE>
 
          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, 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."

          (b)  Adding a new paragraph B to Article V (and relettering paragraphs
      B and C as paragraphs C and D, respectively), as follows:

               "B. 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:

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

                                       2
<PAGE>
 
                  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 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.

               2. 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

                                       3
<PAGE>
 
                  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 manner determined by the
                  Board of Directors) in the net asset value, dividends and
                  distributions and liquidation rights of the shares of such
                  class.

               3. 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.

               4. 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

                                       4
<PAGE>
 
                  respective aggregate net asset values of the shares of such
                  series held by them and recorded on the books of the
                  Corporation.

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

               6. 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."

     relettered from paragraph C by this Amendment) of Article V.

          (d)  Striking out the last sentence of subparagraph 2 of paragraph A
     of Article VI.

<PAGE>
 
          (e)  Striking out the last sentence of subparagraph 7 of paragraph A
     of Article VI and inserting in lieu thereof:

          "Any agreement entered into pursuant to said subparagraphs 5 or 6
          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 thereunder, or any other applicable
          Act of Congress hereafter enacted, and no amendment to any agreement
          entered into pursuant to said subparagraph 5 (other than an amendment
          reducing the compensation of the other party thereto) shall be
          effective unless assented to by the affirmative vote of a majority of
          the outstanding voting securities of the Corporation (as such phrase
          is defined in the Investment Company Act of 1940, as amended from time
          to time) entitled to vote on the matter."

          (f)  Striking out the preamble to paragraph B of Article VI, and
     inserting in lieu thereof:

          "Each holder of the shares of capital stock shall be entitled at his
          option, exercisable as hereinafter provided, to require the
          Corporation to purchase all or any part of the shares of its capital
          stock owned by such holder for an amount equal to the proportionate
          interest in the net assets of the Corporation represented by such
          shares determined as hereinafter set forth.  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 proportionate
          interest in such net assets 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."

          (g)  Striking out the preamble to paragraph E of Article VI and the
     portion of subparagraph 1 of paragraph E of Article VI prior to
     subparagraph (a) and inserting in lieu thereof:

               "E.  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 Determination Time
          shall be determined by or pursuant to the direction of the Board of
          Directors as follows:

<PAGE>
 
               1. At times when a series is not classified into multiple
                  classes, the net asset value of each share of stock of a
                  series, at any Determination Time, shall be the quotient,
                  carried out to not less than two decimal points, obtained by
                  dividing the net value of the assets of the Corporation
                  belonging to that series (determined as hereinafter provided)
                  as of such Determination Time by the total number of shares of
                  that series then outstanding, including all shares of that
                  series which the Corporation has agreed to sell for which the
                  price has been 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 any 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 subparagraph 2 of paragraph B 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
                  subparagraph 1 of paragraph B of Article V) at such
                  determination time, all determined in accordance with sound
                  accounting practice and giving effect to the following:"

          (h)  Adding a new subparagraph 2 to paragraph E of Article VI (and
     relettering subparagraph 2 as subparagraph 3), as follows:

              "2. 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

                                       7
<PAGE>
 
                    subparagraphs 1 and 3 of this paragraph E with appropriate
                    adjustments to reflect differing allocations of liabilities
                    and expenses of such series between or among such classes to
                    such extent as may be provided in or determined pursuant to
                    Articles Supplementary filed for record with the State
                    Department of Assessments and Taxation of Maryland or as may
                    otherwise be determined by the Board of Directors."

          (i)  Adding a new paragraph F to Article VI (and relettering
     paragraphs F and G as paragraphs G and H, respectively), as follows:

               "F.  The presence in person or by proxy of the holders of one-
          third of the shares of capital stock of the Corporation issued and
          outstanding and entitled to vote thereat shall constitute a quorum for
          the transaction at any business at all meetings of the shareholders,
          except as otherwise provided by law or in these Articles of
          Incorporation and except that where the holders of shares of stock of
          any series or class are entitled to a separate vote as such series or
          class (each such series or class, a "Separate Class") or where the
          holders of shares of stock of two or more (but not all) series or
          classes are required to vote as a single series or class (each such
          single series or class, a "Combined Class"), the presence in person or
          by proxy of the holders of one-third of the shares of stock of that
          Separate Class or Combined Class, as the case may be, issued and

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


          RULE 12b-1 DISTRIBUTION PLAN AND AGREEMENT dated as of July 12, 1996
by and between LORD ABBETT BOND-DEBENTURE 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.
<PAGE>
 
          2.   Subject to possible reduction as provided below in this paragraph
2, the Fund shall pay to the Distributor fees (i) at the time of sale of Shares
(a) for services, not to exceed .25 of 1% of the net asset value of the Shares
sold and (b) for distribution, not to exceed .75 of 1% of the net asset value of
the Shares sold; and (ii) at each quarter-end after the first anniversary of the
sale of Shares (a) for services, at an annual rate not to exceed .25 of 1% of
the average annual net asset value of Shares outstanding for one year or more
and (b) for distribution, at an annual rate not to exceed .75 of 1% of the
average annual net asset value of Shares outstanding for one year or more. For
purposes of clause (ii) above, (A) Shares issued pursuant to an exchange for
Class C shares of another 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

                                       2
<PAGE>
 
the manner contemplated in paragraph 10 of this Plan) shall approve the timing,
categories and calculation of any payments under this paragraph 3 other than
those referred to in the foregoing sentence.

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

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

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

                                       3
<PAGE>
 
in the operation of this Plan or in any agreement related to this Plan, cast in
person at a meeting called for the purpose of voting on such renewal.

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

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

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

          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.

                                                                   Exhibit 10(b)

                                                      Draft -- February 27, 1996




                   Plans Pursuant to Rule 18f-3(d) under the
                        Investment Company Act of 1940

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

          The Board, including a majority of the non-interested Board members,
has determined that the following separate arrangement and expense allocation,
and the related exchange privileges, of each class of each Fund are in the best
interest of each class of each Fund individually and each Fund as a whole:

<PAGE>
 
          1.   Class Designation. Fund shares shall initially be divided into
               -----------------
Class A shares and Class C shares.

          2.   Sales Charges and Distribution and Service Fees.
              ----------------------------------------------- 

          (a)  Initial Sales Charge. Class A shares will be traditional front-
               --------------------
end sales charge shares, offered at their net asset value ("NAV") plus a sales
charge in the case of each Fund as described in such Fund's Prospectus as from
time to time in effect.

          Class C shares will be offered at their NAV without an initial sales
charge.

          (b)  Service and Distribution Fees. In respect of the Class A shares
               -----------------------------
and Class C shares, each Fund will pay service and distribution fees under plans
adopted for such classes pursuant to Rule 12b-1 under the 1940 Act (each a "12b-
1 Plan").

          Pursuant to a 12b-1 Plan with respect to the Class A shares, if
effective, each Fund will pay (i) at the time such shares are sold, a one-time
                               -
distribution fee of up to 1% of the NAV of the shares sold in the amount of $1
million or more, including sales qualifying at such level under the rights of
accumulation and statement of intention privileges, or to retirement plans with
100 or more eligible employees, as described in the Fund's Prospectus as from
time to time in effect, (ii) a continuing distribution fee
                         --                               

                                       2

<PAGE>
 
at an annual rate of 0.10% of the average daily NAV of the Class A share
accounts of dealers who meet certain sales and redemption criteria, and (iii) a
                                                                         ---   
continuing service fee at an annual rate not to exceed 0.25% of the average
daily NAV of the Class A shares.  The Board will have the authority to increase
the distribution fees payable under such 12b-1 Plan by a vote of the Board,
including a majority of the independent directors thereof, up to an annual
rate of 0.50% of the average daily NAV of the Class A shares.  The effective
dates of various of the 12b-1 Plans for the Class A shares are based on
achievement by the Funds of specified total NAV's for the Class A shares of each
Fund.

     Pursuant to a 12b-1 Plan with respect to the Class C shares, each Fund will
pay a one-time service and distribution fee at the time such shares are sold of
up to 1% of their NAV and a continuing annual fee, commencing 12 months after
the first anniversary of such sale, of up to 1% of the average annual NAV of
such shares then outstanding (each fee comprised of .25% in service fees and
 .75% in distribution fees).

     (c)  Contingent Deferred Reimbursement Charges ("CDRC").  Subject to some
          --------------------------------------------------                  
exceptions, Class A shares subject to the one-time sales distribution fee of up
to 1% under the Rule 12b-1 Plan for the Class A shares will be subject to a CDRC
equal to 1% of the lower of the cost or then NAV of such shares if the shares
are redeemed for cash

                                       3

<PAGE>
 
on or before the end of the twenty-fourth month after the month in which the
shares were purchased.

     Class C shares will be subject to a CDRC equal to 1% of the lower of the
cost or then NAV of the shares if the shares are redeemed for cash before the
first anniversary of their purchase.

     3.  Liability and Expense Allocation.  The following expenses and
         --------------------------------                              
liabilities therefor shall be allocated, to the extent such expenses can
reasonably be identified as relating to a particular class, on a class-specific
basis: (a) fees under a 12b-1 Plan applicable to a specific class (net of any
CDRC paid with respect to shares of such class and retained by the Fund) and any
other costs relating to implementing or amending such Plan, including obtaining
shareholder approval of such Plan or any amendment thereto; (b) transfer and
shareholder servicing agent fees and shareholder servicing costs identifiable as
being attributable to the particular provisions of a specific class; (c)
stationery, printing, postage and delivery expenses related to preparing and
distributing materials such as shareholder reports, prospectuses and proxy
statements to current shareholders of a specific class; (d) Blue Sky 
registration fees incurred by a specific class; (e) Securities and Exchange
Commission registration fees incurred by a specific class; (f) Board fees or
expenses identifiable as

                                       4

<PAGE>
 
being attributable to a specific class; (g) auditor's fees and expense relating
solely to a specific class; (h) litigation expenses and legal fees and expense
relating solely to a specific class; (i) expenses incurred in connection with
shareholders meetings as a result of issues relating solely to a specific class
and (j) other expenses relating solely to a specific class.  All such
liabilities and expenses incurred by a class of shares will be charged directly
to the net assets of the particular class and thus will be borne on a pro rata
basis by the outstanding shares of such class.

     4.  Dividends.  Dividends paid by a Fund as to each class of its shares, to
         ---------                                                              
the extent any dividends are paid, will be calculated in the same manner, will
be paid at the same time, and will be in the same amount, except that any
liabilities and expenses allocated to a class as provided above will be borne
exclusively by that class.

     5.  Net Asset Values.  The NAV of each share of a class of a Fund shall be
         ----------------                                                      
determined in accordance with the Articles of Incorporation or Declaration of
Trust of such Fund with appropriate adjustments to reflect the differing
allocations of liabilities and expenses of such Fund between its classes as
provided above.  [Attached hereto as Exhibit

                                       5

<PAGE>
 
A is a sample calculation of the NAV's of a Class A share and a Class C share.]

     6.  Conversion Features.  Subject to amendment by the Board, no class of
         -------------------                                                 
shares shall be subject to any automatic conversion feature at this time.

     7.  Exchange Privileges.  Except as set forth in the Fund's prospectus,
         -------------------                                                
shares of any class of a Fund may be exchanged, at the holder's option, for
shares of the same class of another Fund, or other Lord Abbett-sponsored fund or
series thereof, without the imposition of any sales charge, fee or other charge.

     Each Plan is qualified by and subject to the terms of the then current
prospectus for the applicable Fund; provided, however, that none of the terms
set forth in any such prospectus shall be inconsistent with the terms contained
herein. The prospectus for each Fund contains additional information about that
Fund's classes and its multiple-class structure.

     Each Plan is being adopted for a Fund with the approval of, and all
material amendments thereto must be approved by, a majority of the Board of such
Fund, including a majority of the Board who are not interested persons of the
Fund.

                      Lord Abbett Bond-Debenture Fund, Inc.
                       Registration Statement on Form N-14
                      -------------------------------------

Ladies and Gentlemen:

          We have acted as counsel to Lord Abbett Bond Debenture Fund, Inc. (the
"Registrant"), a Maryland corporation, in connection with the preparation and
filing with the Securities and Exchange Commission under the Securities Act of
1933, as amended, of a Registration Statement on Form N-14 (File No. 811-2145)
the "Registration Statement"), relating to the issuance of shares of the capital
stock of the Registrant.

          Such shares are to be established and designated as the Class C shares
(the "Class C shares"). The Class C shares are to be issued to Lord Abbett Bond-
Debenture Trust (the "Acquired Trust"), a series of Lord Abbett Securities Trust
(the "Securities Trust"), a Delaware business trust, pursuant to an Agreement
and Plan of Reorganization (the
<PAGE>
 
Lord Abbett Bond-Debenture Fund, Inc.
Page 2


"Acquired Trust Plan") between the Securities Trust, on behalf of the Acquired
Trust, and the Registrant substantially in the form of Exhibit A included in
Part A of the Registration Statement. Such issuance of the Class C shares is to
be made in connection with the acquisition by the Registrant of the assets of,
and the assumption by the Registrant of the liabilities of, the Acquired Trust.

          In so acting, we have examined and relied upon the originals, or
copies certified or otherwise identified to our satisfaction, of such documents,
records, certificates and other instruments and have made such other
investigations as in our judgment are necessary or appropriate to enable us to
render the opinion expressed below. We have not, however, undertaken any
independent investigation of any factual matter set forth in any of the
foregoing.

          Based on the foregoing, we are of the following opinion:

          Assuming that the Acquired Trust and the Registrant duly execute and
     deliver the Acquired Trust Plan, that the Acquired Trust Plan and the
     reorganization provided for thereby are duly approved by the shareholders
     of the Acquired Trust, that the transactions contemplated by the Acquired
     Trust Plan are duly consummated and that the charter documents
     substantially in the forms of Exhibits 1(b), 1(c) and 1(d) to the
     Registration Statement are duly approved and filed with the State
     Department of Assessments and Taxation of Maryland, the Class C shares
     issued pursuant to the Acquired Trust Plan will be legally issued, fully
     paid and non-assessable.

          This opinion is limited solely to the federal law of the United States
and the Maryland General Corporation Law as in effect on the date hereof and the
relevant facts that exist as of the date hereof.  Without limiting the
generality of the foregoing, we express no opinion concerning other laws of the
State of Maryland, including the securities laws of such state, or the laws of
any other jurisdiction other than the United States.  No assurance can be given
that the law or facts will not change, and we have not undertaken to advise you
or any other person with respect to any event subsequent to the date hereof.

consent, no other persons are entitled to rely on this opinion.  We consent to
the filing of this opinion as an Exhibit to the Registration Statement.  In
giving such consent, we do not thereby concede that we are within the category
of persons whose consent is required under Section 7 of the Securities Act of
1933 or the Rules and Regulations of the Securities and Exchange Commission

Ladies and Gentlemen:

          We have acted as counsel to Lord Abbett Bond-Debenture Fund, Inc., a
Maryland corporation,("Acquiring Fund"), and Lord Abbett Securities Trust, a
Delaware business trust (the "Trust"), acting on behalf of its series, Lord
Abbett Bond-Debenture Trust ("Acquired Fund"), in connection with the proposed
acquisition (the "Reorganization") of all of the assets of Acquired Fund by

Lord Abbett
  Bond-Debenture Fund, Inc.
Lord Abbett Securities Trust 2                            [Date of the Closing]


Acquiring Fund pursuant to the Agreement and Plan of Reorganization dated as of
_______ __, 1996, by and between Acquiring Fund and the Trust on behalf of
Acquired Fund (the "Reorganization Agreement").

          In so acting, we have participated in the preparation of the
Reorganization Agreement and the preparation and filing by Acquiring Fund with
the Securities and Exchange Commission on February __, 1996 of a Registration
Statement on Form N-14, containing a Proxy Statement and Prospectus relating to
the proposed Reorganization and to the shares of common stock of Acquiring Fund
to be issued to Acquired Fund shareholders in the Reorganization pursuant to the
Reorganization Agreement.

          As required by Section 8.5 of the Reorganization Agreement, you have
requested that we render the opinion set forth below. In rendering such opinion,
we have examined and relied upon the accuracy as of the date hereof of the
representations and warranties as to factual matters set forth in the documents
referred to above and the Letters of Representation, dated as of the date
hereof, that you have provided to us, copies of which are attached hereto. We
have also examined the originals, or copies certified or otherwise identified to
our satisfaction, of such records, documents, certificates or other instruments
as in our judgment are necessary or appropriate to enable us to render the
opinions set forth below. We have not, however, undertaken any independent
investigation of any factual matter set forth in any of the foregoing.

          Subject to the foregoing and to the qualifications and limitations set
forth herein, and assuming that the Reorganization is consummated in accordance
with the Reorganization Agreement and as described in the Registration
Statement, we are of the opinion that for United States federal income tax
purposes:

          1.  The acquisition by Acquiring Fund of all of the assets of Acquired
     Fund solely in exchange for the issuance of Acquiring Fund shares to
     Acquired Fund and the assumption of all of the Acquired Fund liabilities by
     Acquiring Fund, followed by the distribution by Acquired Fund, in

Lord Abbett
  Bond-Debenture Fund, Inc.

     complete liquidation, of the Acquiring Fund shares to Acquired Fund
     shareholders in exchange for their Acquired Fund shares, will be treated as
     a "reorganization" within the meaning of Section 368(a) of the Internal
     Revenue Code of 1986, as amended (the "Code").

          2.  Acquiring Fund and Acquired Fund will each be "a party to the
     reorganization" within the meaning of Section 368(b) of the Code.

          3.  No gain or loss will be recognized by Acquired Fund upon the
     transfer of Acquired Fund's assets to Acquiring Fund in exchange for
     Acquiring Fund shares and the assumption by Acquiring Fund of the
     liabilities of Acquired Fund or upon the distribution of Acquiring Fund
     shares to Acquired Fund's shareholders.

          4.  No gain or loss will be recognized by Acquiring Fund upon the
     receipt of the assets of Acquired Fund in exchange for Acquiring Fund
     shares and the assumption by Acquiring Fund of the liabilities of Acquired
     Fund.

          5.  No gain or loss will be recognized by shareholders of Acquired
     Fund upon the exchange of their Acquired Fund shares for Acquiring Fund
     shares.

          6.  The aggregate tax basis of the Acquiring Fund shares received by
     any Acquired Fund shareholder pursuant to the Reorganization will be the
     same as the aggregate tax basis of the Acquired Fund shares held by such
     shareholder immediately prior to the Reorganization, and the holding period
     for the Acquiring Fund shares to be received by any Acquired Fund
     shareholder will include the period during which the Acquired Fund shares
     exchanged therefor were held by such shareholder (provided that the
     Acquired Fund shares are held as capital assets on the date of the
     Reorganization).

          7.  The tax basis of Acquired Fund's assets acquired by Acquiring Fund
     will be the same as the tax basis of such assets to Acquired Fund
     immediately prior

     to the Reorganization, and the holding period of the assets of Acquired
     Fund in the hands of Acquiring Fund will include the period during which
     those assets were held by Acquired Fund.

          This opinion is limited solely to the federal law of the United States
as in effect on the date hereof and the relevant facts that exist as of the date
hereof.  No assurance can be given that the law or facts will not change, and we

Dear Associate Chief Counsel (Domestic):

classes of shares will not affect the classification of any such fund as a
regulated investment company under section 851(a) and (h) of the Code.

Internal Revenue Service               2                        January 26, 1996


          We now wish to request that you issue similar rulings with respect to
two additional funds, Growth and Income Trust of Lord Abbett Securities Trust
and the Small-Cap Series of Lord Abbett Research Fund, Inc.  All defined terms
in this request have the meanings set forth in the Original Request.

          Growth and Income Trust
          -----------------------

          Growth and Income Trust (TIN 13-3731505) is a series of Lord Abbett
Securities Trust ("Securities Trust"), an open-end management investment company
organized as a Delaware business trust on February 26, 1993.  Securities Trust
is registered as an open-end management investment company under the 1940 Act.
A copy of Securities Trust's most recent Post-Effective Amendment to its
Registration Statement on Form N-1A, dated June 15, 1995, is attached as Exhibit
N.

          Growth and Income Trust is diversified and has met and intends to
continue to meet the diversification rules under Subchapter M of the Internal
Revenue Code.  Its taxable year ends on October 31.  The investment objective of
Growth and Income Trust is long-term growth of capital and income without
excessive fluctuations in market value.  It normally invests in common stocks of
large, seasoned companies in sound financial condition which are expected to
show above-average price appreciation.

          Growth and Income Trust currently has outstanding only a single class
of shares.  All shares have equal voting rights and equal rights with respect to
dividends, assets, and liquidation.  They are fully paid and non-assessable when
issued and have no preemptive or conversion rights.  There are no restrictions
on transfer.

          Growth and Income Trust has adopted a Rule 12b-1 Plan.  Under the 12b-
1 Plan, Growth and Income Trust pays Lord Abbett (1) a service fee and a
                                                  -                     
distribution fee, at the time shares are sold, not to exceed .25% and .75%,
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 .25% and .75%, respectively, of the
average annual net asset value of such shares outstanding (payments with respect
to shares
<PAGE>
 
Internal Revenue Service               3                        January 26, 1996

not outstanding during the full quarter are prorated).  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.  Lord Abbett may
retain from the quarterly distribution fee, for the payment of distribution
expenses incurred directly by it, an amount not to exceed .10% of the average
annual net asset value of such shares outstanding.  No dealer shall receive for
service more than .25% of the average annual net asset value of shares sold by
the dealer.  Lord Abbett is required to pay the sales distribution fee to
dealers as compensation for selling Growth and Income Trust's shares.

          If shares of Growth and Income Trust are redeemed for cash before the
first anniversary of their purchase, the redeeming shareholder will be required
to pay a contingent deferred reimbursement charge of 1% of the lower of cost or
the then net asset value of the shares redeemed.  If the shares are exchanged
into another series of Securities Trust or Lord Abbett U.S. Government
Securities Money Market Fund ("GSMMF") and subsequently redeemed before the
first anniversary of their original purchase, the charge will be collected by
the other series or GSMMF for Growth and Income Trust.

          The Small-Cap Series
          --------------------

          The Small-Cap Series (TIN 13-3862601) is a newly-organized series of
Research Fund, which is described at page 9 of the Original Request.  It plans
to begin offering its shares on or after February 20, 1996.  The Small-Cap
Series intends to qualify as a regulated investment company under Subchapter M
of the Internal Revenue Code.  The Small Cap Series' taxable year ends on
November 30.  The investment objective of the Small-Cap Series is to seek long-
term capital appreciation through investments primarily in equity securities
which are believed to be undervalued in the marketplace. A copy of Research
Fund's most recent amendment to its Form N-1A describing the Small-Cap Series,
which was filed with the Securities and Exchange Commission on December 7, 1995,
is attached as Exhibit O.

          The Small-Cap Series currently has outstanding only a single class of
shares, $.001 par value.  All shares have
<PAGE>
 
Internal Revenue Service                 4                      January 26, 1996

equal voting rights and equal rights with respect to dividends, assets, and
liquidation.  They are fully paid and nonassessable when issued and have no
preemptive or conversion rights.  There are no restrictions on transfer.

          As stated in the Original Request, Research Fund has not adopted a
Rule 12b-1 Plan.

          The Statement of Facts, Rulings Requested, Discussion and Procedural
Statements with respect to Growth and Income Trust and the Small-Cap Series are
otherwise as set forth in the Original Request, except that "Revenue Procedure
96-1" is substituted for "Revenue Procedure 95-1" and the check for the user fee
specified in section 14.02 and Appendix A of Revenue Procedure 96-1 is endorsed
in the amount of $300.

                                                   Respectfully submitted,

PROPOSED TRANSACTIONS
- - - - - ---------------------

          Management of the Lord Abbett Funds/2/ has proposed that the Articles
of Incorporation or Declaration of Trust of each Fund be amended to permit each
to issue additional, separate classes of shares with characteristics designed
for particular markets. A draft of the proxy materials soliciting the approval
of each Fund's shareholders for the amendment to the Articles of Incorporation
or Declaration of Trust permitting the issuance of separate classes (including
the text of the proposed amendment), will be submitted when it is filed with the
Securities and Exchange Commission./3/

          Subject to the shareholders' approval of the amendments, the Board of
Directors of each Fund will redesignate its currently outstanding shares as a
separate class and will authorize the issuance of additional separate classes of
shares of each series ("Additional Classes").

          The precise terms of each Additional Class will be determined by the
Board of Directors of each Fund at the time of issuance. However, each Fund
represents that, although the Additional Classes may be sold under different
sales arrangements, the shares of the Additional Classes offered by each Fund
will otherwise be identical to the currently outstanding shares of that Fund,
with the following exceptions:

          (i)  A 12b-1 Fee equal to a percentage of average daily net asset
           -                                                               
     value may or may not be charged under a 12b-1 Plan to each of the
     Additional Classes, and the level of 12b-1 Fees may vary from class to
     class.  The

______________________

2. As used herein, the term "Fund" refers to each taxpayer designated on
   schedule A, regardless of whether the entity is structured as a separate
   corporation or trust or as a series of a corporation or trust.

3. No shareholder vote is required for Tax-Free Trust. A copy of its proposed
   amendment will be submitted with the other amendments. No amendment is
   required for Investment Trust.

Internal Revenue Service               16                       October 19, 1995


     Additional Classes may bear different service and distribution fees under
     12b-1 Plans, may bear different costs relating to shareholder or director
     (trustee) approval of or amendments to 12b-1 Plans or may have front end
     loads or other sales charges or non-12b-1 shareholder service plan fees
     (collectively, "Plan Payments"). Services provided pursuant to 12b-1 Plans
     or non-12b-1 shareholder service plans may include (1) preparing,
     producing, and delivering printed materials to shareholders, including
     reports, prospectuses and proxies, (2) advertising, and (3) promoting and
     selling shares. Such services may also include certain administrative
     services associated with (1) maintaining and processing customer accounts
     and records, such as data maintenance and communication, and systems
     servicing; (2) handling shareholder inquiries and communications, including
     postage and shipping charges; (3) recordkeeping and shareholder accounting,
     including related storage and shipping; (4) shareholder servicing; and (5)
     processing dividend payments on behalf of customers.

          (ii)  Each class will bear different "Specially Allocated Expenses,"
           --                                                                 
     which are Fund expenses and fees (other than Plan Payments) allocated to
     that class and not allocated on a pro rata basis across different classes.
     These may include registration fees under state Blue Sky laws; SEC
     registration fees; accounting expenses; auditors fees, litigation expenses
     and legal fees and expenses relating to a class; and expenses incurred in
     connection with shareholder or director (trustee) meetings as a result of
     issues relating to a class.

          Specially Allocated Expenses may also include other expenses related
     solely to a particular class of shareholders and administrative expenses
     required to support shareholders of that class, to the extent that such
     expenses are incidental to the class expenses specifically enumerated in
     the paragraph above.

          The taxpayer represents that the only expenses allocated to the
     classes disproportionately will be Specially Allocated Expenses and Plan
     Payments. The Specially Allocated Expenses allocated to each share of
<PAGE>
 
Internal Revenue Service               17                       October 19, 1995


     a class during a year will differ from the Specially Allocated Expenses
     allocated to each share of any other class of the same Fund by less than 50
     basis points of the average daily net asset value of the class of shares of
     such Fund with the smallest average net asset value.

          Any distribution on shares of a class will differ from the
     distribution on shares of other classes of the same Fund only as a result
     of the allocation of Specially Allocated Expenses and Plan Payments and the
     effects of such allocation.

          (iii)  The designation of each class of shares of a Fund will be
           ---                                                            
     different.

          (iv)  The effect of the sales charges for each class will differ.
           --                                                              

          (v)  Voting rights on matters affecting only one class will vary in
           -                                                                 
     accordance with the procedures set forth in Rule 12b-1 and Rule 18f-3.

          (vi)  Different classes of shares may have different conversion
           --                                                            
     features.

          (vii)  Each class may have different privileges of reinvestment with a
           ---                                                                  
     reduced sales load after redemption, as will be specified from time to time
     in the relevant prospectus disclosure.

          (viii)  Different classes of shares may have different exchange
     privileges.

          Dividends paid by each Fund with respect to various classes of shares
will be calculated in the same manner and at the same time on the same day.
Amounts payable as dividends, however, will vary because of the differing
amounts of Specially Allocated Expenses and Plan Payments borne exclusively by a
particular class.

          The net asset value per share and net income per share of a particular
class will also vary owing to the differing amounts of Specially Allocated
Expenses and Plan Payments.  Because gross income and other expenses would be
<PAGE>
 
Internal Revenue Service               18                       October 19, 1995


allocated daily to a class based on its net asset value, more income would be
allocated per share to classes with lower per share class expenses than to
classes with higher per share expenses. Further, this net income differential
would tend to increase during the course of the dividend period until the
accumulated income is declared as a dividend at the close of the period.

          On each day that it determines net asset value per share each Fund
will first allocate its gross investment income less expenses other than
Specially Allocated Expenses or Plan Payments among all shares of that Fund
regardless of class in accordance with net asset values determined as of the
preceding day. Specially Allocated Expenses and Plan Payments allocated to a
particular class will then be subtracted from the amounts otherwise allocable to
that class, to determine the net asset value of the shares of each class.

                               -----------------

          We respectfully request that you rule that:

     1.   The adoption of the proposed multiple class system will not cause
          dividends declared and paid by any of the Funds to be preferential
          dividends within the meaning of section 562(c) of the Code and each
          Fund will therefore be eligible for the dividends paid deduction under
          sections 561 and 852 of the Code, provided that each Fund otherwise
          continues to meet the criteria of those two sections.

     2.   The creation of multiple classes of shares within each Fund will not
          affect the classification of each Fund as a regulated investment
          company under section 851(a) or (h).

     3.   There will be no federal income tax consequences to the holders of
          currently outstanding shares of any Fund as a result of the
          reclassification of the shares held by such holders as a separate
          class of each Fund.

                              DISCUSSION
                              ----------

          Each share of each Additional Class that will be offered by each Fund
will represent an equal interest in the same portfolio of investments and
(except as specified in paragraphs (i) through (viii) above) will have voting,
dividend, and liquidation rights that are identical to those of the currently
outstanding shares of that Fund. Each class of new shares may be subject to its
own 12b-1 Fees, non-12b-1 shareholder service plan fees or other Plan Payments
and some of the classes may be subject to different levels of Plan Payments.
Although Specially Allocated Expenses will be allocated differently between the
classes, each Fund has represented that the Specially Allocated Expenses
allocated to each share of a class during a year will differ from Specially
Allocated Expenses allocated to each share of any other class of the same Fund
by less than 0.50% of the average net asset value per share of the class with
the smallest net asset value per share.

          The facts and representations presented above are similar to those
described in Private Letter Ruling 9522045 (March 7, 1995), Private Letter
Ruling 9422026 (March 1, 1994) and numerous other rulings.

          In those rulings, the Service has stated that for purposes of section
562(c) of the Code, sales loads, 12b-1 Fees and other Plan Payments are
essentially treated as direct and indirect shareholder expenses that should not
be taken into account in determining whether distributions are preferential.
Cf., Treas. Reg. (S) 1.67-2T(k), Examples 3 and 4. As a result, amounts

distributed with respect to different classes of shares of each Fund will
effectively differ only as a result of the Specially Allocated Expenses, which
will be limited as described in paragraph (ii) above. As noted in the prior
rulings, section 562(c) treats as pro rata those distributions that differ by a
de minimis amount because of the allocation of fund expenses. H.R. Rep. No.
1860, 75th Cong., 3d Sess. 23 (1938). Accordingly, dividends paid by each Fund
after the adoption of the multiple class system will not be preferential within
the meaning of section 562(c) of the Code.

          Moreover, the Service has found in the prior rulings that differences
in class-designations, voting

Internal Revenue Service               20                       October 19, 1995


rights, sales charges and class-specific expenses, like those described above,
are insufficient to cause the shares to be classified as different classes for
purposes of the Code. As a result, the designation of outstanding shares as
belonging to a particular class should have no tax effect.

          As a result, the adoption of the multiple class system as described
above should have no effect on the qualification of each Fund as a regulated
investment company under sections 851 and 852 of the Code.

                             PROCEDURAL STATEMENTS
                             ---------------------

          To the best of the knowledge of each Fund and its representative,
issues identical to those involved in this ruling request are not raised in an
earlier return of any Fund (or in a return for any year of a related taxpayer
within the meaning of section 267 of the Code, or of a member of an affiliated
group of which any Fund is also a member within the meaning of section 1504).

          To the best of the knowledge of each Fund and its representative, the
Service has not previously ruled on issues identical or similar to those raised
in this ruling request for any Fund (or a related taxpayer within the meaning of
section 267 of the Code, or a member of an affiliated group within the meaning
of section 1504) or a predecessor, nor has any Fund, a related taxpayer, a
predecessor, or their representatives previously submitted the same or similar
issues to the Service but withdrawn them before a letter ruling or determination
letter was issued.

          To the best of the knowledge of each Fund and its representative, the
taxpayer, a related taxpayer, or a predecessor has not previously submitted a
request involving the same or a similar issue that is currently pending with the
Service, nor is the taxpayer or a related taxpayer presently submitting another
request involving the same or similar issues to the Service at the same time as
this request.

          Each Fund believes that the law in connection with this ruling request
is unclear and that the issues raised herein are not adequately addressed by the
relevant authorities.

Dear Mr. Rosen:

          This ruling replies to your letters dated October 19, 1995, and
January 26, 1996, submitted an behalf of Funds I through 29, in which you
request that the Internal Revenue Service rule as follows:

          (1)  that the adoption of the proposed multiple class system will not
     cause dividends paid on each class of shares issued by the funds to be
     preferential dividends under section 562(c) of the Code, and therefore
     that each fund will be eligible for the dividends-paid deduction under
     sections 561 and 852(b)(2)(D) of the Code;

          (2)  that the creation of multiple classes of shares will not affect
     the classification of the Funds as regulated investment companies (RICs)
     under section 851 of the Code; and

          (3)  that the redesignation of currently outstanding shares of each
     fund as a separate class of shares pursuant to the proposed multiple class
     system will not result in gain or loss or in other Federal income tax
     consequences to the holders of currently outstanding shares.

                                       4
<PAGE>
 
                                     FACTS

          Funds are open-end management investment companies registered under
the Investment Company Act of 1940, 15 U.S.C. 80a-1 et seq., as amended (the
                                                    -- ---
1940 Act) , and are structured as corporations, as trusts, or as series of
corporations or trusts. Each qualified as a regulated investment company (RIC)
under Subchapter M, part 1, of the Code. Funds 1 through 7, 10 through 20, and
25 through 27 are incorporated under the laws of State A. Funds 6 and 7, Funds
10, 11, and 29, and Funds 12 through 20 are organized as series funds under the
laws of State A. Funds 8 and 9 are organized as business trusts under the laws
of State B. Funds 21 through 24 are organized as a series fund under the laws of
State C. Fund 28 is organized as a series fund under the laws of State B.

          Investment Advisor and Distributor provides investment advice for
each of the funds. The shares of the funds, with the exception of shares of
Funds 10 and 11, are marketed pursuant to distribution agreement with Investment
Advisor and Distributor.

          Shares of the funds are sold subject to differing sales arrangements.
Under Rule 12b-1 plans adopted by certain of the funds, an annual service fee
equal to a percentage of the average daily net asset value of shares of the fund
is payable to Investment Advisor and Distributor. The level of the annual
service fee varies from fund to fund.  Also payable to Investment Advisor and
Distributor under the Rule 12b-1 plans are one-time sales distribution fees,
payable at the time of sale, on sales of greater than certain specified amounts.
Investment Advisor and Distributor is required to pay the sales distribution
fees to dealers as compensation for selling shares of the funds.

          Funds each have outstanding only a single class of shares.  Funds have
proposed that the articles of incorporation or declaration of trust of each
fund be amended to permit each to issue additional, separate classes of shares
with characteristics designed for particular markets.

          The precise terms of each additional class will be determined by the
Board of Directors of each fund at the time of issuance.  Each fund represents,
however, that although the additional classes may be sold under differing sales
arrangements the shares of the additional classes offered by each fund will
otherwise be identical to outstanding shares of that fund, with the following
exceptions:

                                       5
<PAGE>
 
          (1)  The designation of each class of shares will be different.

          (2)  Different classes of shares may have different conversion
     features.

          (3)  Different classes may have different exchange privileges.

          (4)  Each class may have different privileges of reinvestment with a
     reduced sales load after redemption.

          (5)  The additional classes may adopt Rule 12b-1 plans which bear
     different service and distribution fees or different costs relating to
     approval of or amendments to the Rule 12b-1 plans.  The level of Rule 12b-1
     plan fees may vary from class to class.  Voting rights on matters affecting
     only one class will vary in accordance with the procedures set forth in
     Rule 12b-1 and Rule 18f-3.

          (6)  The additional classes may be sold subject to asset-based sales
     charges and the effect of the sales charges for each class will differ.

          (7)  The additional classes may be sold subject to non-Rule 12b-1 plan
     shareholder services plan fees.

          (8)  Each class will bear different specially allocated expenses. To
     the extent the following classes of expenses can reasonably be identified
     as relating to a particular class, they will be allocated to that class
     and, if so allocated, will be referred to as Class Expenses:

               (a)  registration fees under state Blue Sky laws;
               (b)  SEC registration fees;
               (c)  accounting expenses, including auditors' fees;
               (d)  legal fees, including expenses of litigation;
               (e)  expenses incurred in connection with shareholder, director,
          or trustee meetings; and
               (f)  administrative expenses required to support shareholders of
          a particular class, to the


                                       6
<PAGE>
 
          extent incidental to the expenses enumerated in (a) through (e).

          The funds represent that the only expenses allocated to the classes
disproportionately are Class Expenses, Rule 12b-1 plan fees and shareholder
services plan fees. The Class Expenses allocated to each share of a class during
a year will differ from the Class Expenses allocated to each share of any other
class of the same fund by less than a% of the average daily net asset value of
                                    -                                         
the class of shares with the smallest average net asset value.

          Any distribution on shares of a class will differ from the
distribution on shares of other classes of the same fund only as a result of the
allocation of Class Expenses, Rule 12b-1 plan fees and shareholder services plan
fees and the effects of such allocation.

          Investment Advisor and Distributor may waive a Rule 12b-1 plan fee in
whole or in part.

          Dividends paid by each fund with respect to various classes of shares
will be calculated in the same manner and at the same time on the same day.
Amounts pay  able as dividends, however, will vary because of the differing
amounts of Class Expenses, Rule 12b-1 plan fees, and shareholder services plan
fees borne exclusively by a particular class.

                                      LAW

          Section 851(a) defines a RIC, in part, as a domestic corporation
registered under the 1940 Act as a management company.

          Section 851 (b) limits the definition of a RIC to a corporation
meeting certain election, gross income, and diversification requirements.

          Section 851(h) of the Code provides a special rule for a RIC having
more than one fund. This provision treats each fund as a separate corporation
for all purposes of the Code, other than the definitional requirement of section
851(a).

          A corporation that is a RIC within the meaning of section 851 and that
is taxable under Subchapter M, part I, pays tax on its investment company
taxable income under section 852(b)(2) and on the excess, if any, of its net


                                       7
<PAGE>
 
capital gain over its deduction for dividends paid, determined with reference
to capital gains dividends only under section 852(b)(3).

          Section 852 provides that a RIC is not taxable under Subchapter M,
part I, unless its deduction for dividends paid (as that term is defined in
section 561(a) with certain modifications) for the taxable year equals or 
exceeds a specified portion of its taxable income (with certain adjustments)
and its net tax-exempt interest income.

          Section 561(a) defines the deduction for dividends paid, for purposes
of section 852, to include dividends paid during the taxable year.

          Section 562(a) states that the term "dividend", except as otherwise
provided, includes only dividends described in section 316, which provides a
definition of dividends for purposes of corporate distributions.

          Section 316(a) defines the term "dividend" as any distribution of
property made by a corporation to its shareholders (1) out of its earnings and
                                                    -                         
profits (E & P) accumulated after February 28, 1913, or (2) out of its E & P of
                                                         -                     
the taxable year (computed as of the close of the taxable year without
diminution by reason of any distributions made during the taxable year), without
regard to the amount of the E & P at the time the distribution was made.

          Section 562(c) provides that the amount of any distribution shall not
be considered as a dividend for purposes of the dividends paid deduction under
section 561 unless the distribution is pro rata, does not prefer any shares of
stock of a class over other shares of stock of that same class, and does not
prefer one class of stock over another class except to the extent the former
class is entitled (without reference to waivers of their rights by shareholders)
to be preferred.

          The legislative history and regulations show that each shareholder
within a class, as that term is used in section 562(c), has certain inherent
rights. The Revenue Act of 1936: Hearings on H.R. 12395 Before the Senate Comm.
        -----------------------------------------------------------------------
on Finance, 74th Cong., 2d Sess. 62 (1936); H.R. Rep. No. 1860, 75th Cong., 3d
- - - - - ----------                                                                    
Sess. 23 (1938); section 1.562-2 of the Income Tax Regulations.  Each
shareholder within a class has the right to receive the same distribution an
each of his shares belonging to the class as every other shareholder within the
class.  In addition, the class has the right not


                                       8
<PAGE>
 
to receive less than that to which it is entitled when compared to other
classes.

          A class for purposes of section 562(c), therefore, is a group of
shareholders whose rights are so closely aligned and so different from other
shareholders' rights as to warrant a conclusion that members of the group should
all be treated the same and should be protected against the infringement of
shareholders outside the group with respect to distributions.  For example,
section 1.562-2(b), Example (3) of the income Tax Regulations indicates that
cumulative preferred and common stock may form two classes for these purposes.
Among the characteristics that cause cumulative preferred shareholders to be
viewed as a unit separate from common shareholders is their right to certain
preferences on distributions, on redemption, and on liquidation, and their right
to vote to protect those preferences.

                                   ANALYSIS

          In this case, shares proposed under the multiple class distribution
system represent an equal interest in the same fund of investments and will be
identical in all ways, except as follows:

          1.  Each class of shares will have a different designation.

          2.  The amount and type of asset-based sales load, if any, may differ
     on each class of shares.

          3.  The amounts assessed to a class as a result of a shareholder
     servicing plan may differ.

          4.  The Class Expanses enumerated above will be allocated separately
     to the class of shares to which they are attributable.

          5.  Certain classes may adopt Rule 12b-1 plans which bear different
     service and distribution fees or different costs relating to approval of or
     amendments to the Rule 12b-1 plans.  The level of Rule 12b-1 plan fees may
     vary from class to class.  Voting rights on matters affecting only one
     class will vary in accordance with the procedures act forth in Rule 12b-1
     and Rule l8f-3.

          6.  Different classes of shares may have different conversion
     features.

                                       9
<PAGE>
 
          7.  Different classes may have different privileges of reinvestment
     with a reduced sales load after redemption.

          8.  Different classes of shares may have different exchange
     privileges.

          These differences alone are insufficient to cause the shares proposed
under the multiple class distribution system to be treated as different classes
of shares under section 562(c).

          The Rule 12b-1 fee is a fund expense for purposes of computing
investment company taxable income because it is paid by a fund from fund assets,
unlike a front-end  sales load, which is viewed as a shareholder cost.  See 
                                                                        ---
United States v. Cartwright, 411 U.S. 546 (1973), aff'q 457 F.2d 567 (1972), in
- - - - - ---------------------------                       -----
which the Supreme Court describes a front-end sales load as a type of brokerage
commission that is a shareholder cost. Nonetheless, fees paid pursuant to Rule
12b-1 plans are akin to front-end sales loads because both amounts are primarily
for distribution expenses. The Securities and Exchange Commission has described
Rule 12b-1 plan fees as substitutes for front-end sales loads. See Exemptions
                                                               --- ----------

16,431, 53 FR 23,258 at 23,270 (June 21, 1988).  Thus, it appears that fees paid
pursuant to a Rule 12b-1 plan indirectly are shareholder expenses.  A fund is
never out-of-pocket for amounts paid under the Rule 12b-1 plan; it is reimbursed
for these outlays by shareholders participating in the plan.

          Under this analysis, a Rule 12b-1 fee can be considered an indirect
shareholder expense in determining whether distributions are preferential under
section 562(c) of the Code.  Payments made pursuant to shareholder servicing
agreements also must be considered in determining whether a fund's distributions
are preferential.

          When the Rule 12b-1 plan fees and fees payable under shareholder
servicing agreements are taken into account, the amounts distributed on the
shares of a fund differ by less than a%, which is de mininis.  Section 562(c) of
                                     -                                          
the Code treats as pro rata those distributions that

                                      10
<PAGE>
 
differ by a de minimis amount.  H.R. Rep. No. 1860, 75th Cong., 3d Sess. 23
(1938).

          We conclude from this analysis that each fund has only a single class
of stock. The differences specified above are insufficient to cause the shares
to be classified as different classes under section 562(c) of the Code. The
rights of all shareholders are so closely aligned and similar as to mandate
that all shareholders, who will have the benefit of the same economic
distributions, should be treated as a single class and that the conversion of
shares within that single class will have no tax affect.

                                   HOLDINGS

          Based on the facts as represented by the funds, and provided that each
fund otherwise meets the criteria of sections 561(a) and 852, we rule as
follows:

          (1)  that the adoption of the proposed multiple class system will not
     cause dividends paid on each class of shares issued by the funds to be
     preferential dividends under section 562(c) of the Code, and therefore
     that each fund will be eligible for the dividends-paid deduction under
     sections 561 and 852(b)(2)(D) of the Code,

          (2)  that the creation of multiple classes of shares will not affect
     the classification of the Funds as regulated investment companies (RICs)
     under section 851 of the Code,

     and

          (3)  that the redesignation of currently out  standing shares of each
     fund as a separate class of shares pursuant to the proposed multiple class
     system will not result in gain or loss or in other Federal income tax
     consequences to the holders of currently outstanding shares.

          Except as specifically ruled upon above, no opinion is expressed or
implied regarding the Federal tax aspects of this transaction.  We express no
opinion as to whether each fund will qualify as a RIC that is taxable under
Subchapter M, part 1, if expenses other than the Rule 12b-1 fees, fees paid
pursuant to shareholder servicing plans, and the Class Expenses described in
this letter are allocated to the shareholders disproportionately.


                                      11
<PAGE>
 
          This ruling is directed only to the funds. Section 6110(j)(3) of the
Code provides that it may not be used or cited as precedent.

          A copy of this letter Should be attached to the Federal income tax
return of each fund for each taxable year in which the fund has outstanding
classes of shares described above.

                     IMPORTANT NEWS FROM LORD, ABBETT & CO.



We want to give you  advance  notice of some  changes  we will be  proposing  to
shareholders. As you know, Lord Abbett currently offers front-end load and level
load funds through two separate groups: the Lord Abbett Family of Funds and Lord
Abbett Counsel Group, respectively. In general, we are proposing a consolidation
of the  second  group  into the first  group,  which  would be  achieved  by the
issuance of Class A shares to represent  the Family of Funds and the issuance of
Class C shares to represent the former Counsel Group. Additionally, we intend to
offer B shares  in the near  future.  Many of you have  asked  for more  pricing
alternatives  and this  proxy  should  enable us to respond  to your  needs.  In
addition to offering more pricing  options,  we are  recommending  other changes
that  will  allow  for more  flexibility  in our  funds'  management  and in the
distribution of our funds' shares.

Shareholders  will receive proxy materials  describing these proposed changes in
April. We ask that you encourage your clients to vote their proxies promptly, as
additional  solicitations are costly to their funds. The shareholder  meeting is
scheduled for June 19, 1996. Soon thereafter, we will notify you of all approved
changes.

We believe these  changes will enhance our funds'  competitive  positioning.  We
appreciate  any efforts you can make in helping us secure a quorum and thank you
for your continued support.






                        LETTER TO SHAREHOLDERS RE: PROXY

                           (To go on Fund letterhead)



March __, 1996



Dear Shareholder:

In April, you will receive a proxy statement and ballot, requesting your vote on
several  important  proposals.  These proposed  changes are designed to maintain
your Fund's competitive position and to provide more management and distribution
flexibility. The proxy materials will describe all of the proposed changes.

We  ask  that  you  please  vote  your  proxy/proxies  promptly,  as  additional
solicitations are costly to your Fund. The shareholder  meeting is scheduled for
June 19, 1996. Soon thereafter, we will notify you of all approved changes.

We appreciate your cooperation in promptly returning your proxy card and we look
forward to continuing helping you meet your financial goals.



Sincerely,



Ronald P. Lynch
Chairman
