       [Letterhead of Lord Abbett California Tax-Free Income Fund, Inc.]

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




Dear Shareholder,

          Your Board of Directors has determined that it will be advantageous
for your Fund to reorganize itself into a new series of Lord Abbett Tax-Free
Income Fund, Inc. to benefit from the administration efficiencies that should
flow from being a series of a larger investment company. This new fund (the
"Acquiring Fund") is to be called the California Series of Lord Abbett Tax-Free
Income Fund, Inc.

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

          As part of the reorganization, the Acquiring Fund will enter into an
investment management agreement with Lord, Abbett & Co. that will be
substantially the same as the current management agreement between Lord, Abbett
& Co. and your Fund.  The Acquiring Fund will be operated in the same manner as
your Fund except for several changes which are intended to maintain its
competitive position and to provide more flexibility in managing its investment
portfolio.  Under these changes, the Acquiring Fund will implement a multi-class
structure intended to enable investors to choose a distribution option that
suits their individual situations.  The 12b-1 Plan and Distribution Agreement of
the Acquiring Fund will differ in several respects from the 12b-1 Plan of your
Fund.  These differences, and their estimated effect on expenses, are described
in the enclosed materials.  Finally, the investment objective of the Acquiring
Fund has been slightly modified from that of your Fund and the investment
policies and restrictions have been simplified to provide greater flexibility.

          You are also being asked to vote on the election of directors of your
Fund and to ratify the selection of Deloitte & Touche LLP as your Fund's
independent accountants. A shareholder vote is required on these two matters in
the event that the proposed reorganization will not be consummated.

          Shareholders of another investment company, California Tax-Free Income
Trust (the "Acquired Trust"), a series of Lord Abbett Securities Trust, are also
being asked to vote on a proposed acquisition by the Acquiring Fund of that
trust.  The Acquired Trust, which is much smaller than your Fund, has investment
objectives identical to those of your Fund and has similar investment policies.
If the shareholders of the Acquired Trust approve that transaction, it will
occur immediately after the proposed reorganization of your Fund. The
shareholders of the Acquired Trust are to receive a class of shares different
from the class to be held by the shareholders of your Fund.  The Board of
Directors of your Fund has determined that this proposed acquisition of the
Acquired Trust is in the best interest of your Fund and its shareholders.  If
the proposed reorganization of your Fund is approved, and all other conditions
to the consummation of the proposed reorganization are satisfied, it will occur
regardless of whether that other transaction is approved or consummated.
<PAGE>
 
          The various matters requiring your vote will be voted upon at a
meeting of shareholders of your Fund 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 proposed reorganization of your Fund is in the best interests of
shareholders, we encourage you to vote in favor of this proposal.

                                  Sincerely,


                                  Ronald P. Lynch

to be held on June 19, 1996                                       April 17, 1996

Notice is given hereby of an annual meeting of the shareholders of Lord Abbett
California Tax-Free Income Fund, Inc. (the "Reorganized Fund").  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 Wednesday, June

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 the California Series (the "Acquiring Fund"), a series of Lord
         Abbett Tax-Free Income Fund, Inc., and the Reorganized Fund providing
         for (a) a reorganization of the Reorganized Fund into the Acquiring
         Fund (the "Reorganization") by means of the transfer of all of the
         assets of the Reorganized Fund to the Acquiring Fund in exchange for
         shares of the Acquiring Fund (to be designated "Class A Shares") and
         the assumption by the Acquiring Fund of all of the liabilities of the
         Reorganized Fund, (b) the distribution of such Class A Shares to the
         shareholders of the Reorganized Fund and (c) the subsequent termination
         of the Reorganized Fund. A vote in favor of this Item 1 will be deemed
         to be a vote to authorize the Reorganized Fund, as the sole shareholder
         of Class A Shares of the Acquiring Fund prior to the Reorganization, to
         (i) 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; and (ii) approve the proposed investment
         management agreement between the Acquiring Fund and Lord, Abbett & Co.

ITEM 2.  In the event the Reorganization is not consummated for any reason:

         (A) To elect directors to serve as members of the Board of Directors of
             the Reorganized Fund; and

         (B) To ratify the selection of Deloitte & Touche LLP as the independent
             public accountants of the Reorganized Fund for the current fiscal
             year.



                                         By order of the Board of Directors

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



Dear Shareholder,

          Lord, Abbett & Co. is the investment manager for two U.S. Government
securities funds with identical investment objectives and similar policies: your
Fund and Lord Abbett California Tax-Free Income Fund, Inc.  The Board of
Directors has recommended that both funds be reorganized into a new series of
Lord Abbett Tax-Free Income Fund, Inc., called the California Series (the
"Acquiring Fund") having a substantially similar objective and similar policies.
To eliminate the offering of substantially similar 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.

          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

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

          The Reorganized Fund and the Securities Trust are open-end diversified
investment management companies.  The Reorganized Fund and the Acquired Trust
seek as high a level of interest income exempt from federal and California
personal income tax as is consistent with preservation of capital.  The Income
Fund is also an open-end diversified investment management company.  It consists
of nine tax-free income series in addition to the Acquiring Fund.  The Acquiring
Fund is a new series of Income Fund that will seek as high a level of interest
income exempt from federal and California personal income tax as is consistent
with reasonable risk.  Lord Abbett serves as investment manager to the
Reorganized Fund and the Acquired Trust and will serve as investment manager of
the Acquiring Fund under an investment management agreement substantially the
same as the current investment management agreement of the Reorganized Fund (see
"Comparative Information about the Funds -- Management Agreements").
<PAGE>
 
          The Class A shares and the Class C shares will share pro-rata 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 "Information About the
Reorganizations -- Shares of the Acquiring Fund."  The directors of the
Reorganized Fund believe that the proposed Fund Reorganization will enable
shareholders of the Reorganized Fund to benefit from administrative efficiencies
resulting from its being a series of a larger investment company.  The trustees
of the Acquired Trust believe that the proposed Trust Reorganization will enable
the shareholders of the Acquired Trust to benefit from economies of scale while
continuing to invest in a portfolio of securities managed by Lord Abbett under
an investment objective that is substantially similar to that of the Acquired
Trust.  See "Information About the Reorganizations -- Reasons for the
Reorganizations."

          This Proxy Statement and Prospectus sets forth concisely the
information about the Acquiring Fund that shareholders of the Reorganized Fund
and Acquired Trust should know before voting on the Reorganizations. It should
be read and retained for future reference. Attached as Exhibits A(1) and (2) to
this Proxy Statement and Prospectus are copies of the Agreements and Plans of
Reorganization (the "Fund Plan" with respect to the Reorganized Fund and the
"Trust Plan" with respect to the Acquired Trust, and collectively, the "Plans")
for the respective Reorganizations of the Reorganized Fund and the Acquired
Trust. This Proxy Statement and Prospectus is accompanied by the Prospectus of
the Acquiring Fund dated March , 1996 (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 Reorganized Fund dated January 1, 1996, the
Statement of Additional Information of the Lord Abbett Securities Trust dated
December 27, 1994 and the Statement of Additional Information of the Acquiring
Fund dated March , 1996, and (b) the Prospectus of the Reorganized Fund dated
January 1, 1996 (the "Reorganized Fund Prospectus") and the Prospectus of the
Securities Trust dated December 27, 1994 (the "Acquired Trust Prospectus") [a
pre-effective amendment is to be filed to incorporate by reference the final
Prospectus and Statement of Additional Information of the Income Fund and the
Prospectus and Statement of Additional Information of Lord Abbett Securities
Trust to be dated March 1, 1996]. Such Statements of Additional Information and
such Prospectuses are available, upon oral or written request, and at no charge,

               MEETINGS OF SHAREHOLDERS OF THE REORGANIZED FUND
                             AND SECURITIES TRUST

          This Prospectus and Proxy Statement is furnished in connection with
the solicitation of proxies by and on behalf of the Board of Directors of the
Reorganized Fund and the Board of Trustees of Securities Trust to be used at an
Annual Meeting of Shareholders of the Reorganized Fund and a Special Meeting of
Shareholders of Securities Trust and any adjournments thereof. Such meetings are
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, NY 10153.
This Prospectus and Proxy Statement and the enclosed proxy card are first being
mailed to shareholders of the Reorganized Fund and the Acquired Trust on or
about April 17, 1996.

          Approval of the Fund Plan and the Fund Reorganization will require the
affirmative vote of a majority of the outstanding shares of the Reorganized
Fund, and approval of the Trust Plan and the Trust Reorganization will acquire
the affirmative vote of a majority of the shares of the Acquired Trust voted on
the matter.  One-third of the aggregate number of shares of the Acquired Trust
shall be necessary to constitute a quorum for approval of the Trust Plan and the
Trust Reorganization.  To avoid a need to call an Acquiring Fund shareholders'
meeting after the Reorganizations, the shareholders of the Reorganized Fund are
being asked, as part of their vote on the Fund Plan, to authorize the
Reorganized Fund, as the sole shareholder of the Acquiring Fund before the Fund
Reorganization, to (a) approve a proposed distribution plan pursuant to Section
12 of the Investment Company Act of 1940, as amended (the "1940 Act"), and Rule
12b-1 thereunder applicable to the Class A shares, and (b) approve a proposed
investment management agreement between the Acquiring Fund and Lord, Abbett &
Co. ("Lord Abbett") that will be substantially the same as the current
investment management agreement of the Reorganized Fund.  For the same reason,
the shareholders of the Acquired Trust are being asked, as part of their vote on
the Trust Plan, to authorize the Acquired Trust, as the sole Class C shareholder
of the Acquiring Fund before the Trust Reorganization, to approve a proposed
distribution plan that is substantially the same as the current distribution
plan of the Acquired Trust.  A vote in favor of a Reorganization will be deemed
also to be a vote to authorize the Reorganized Fund or the Acquired Trust, as
the case may be, to take such action.

          At the close of business on March 22, 1996 (the "Record Date"), there
were issued and outstanding ____ shares of the Reorganized Fund and ____ shares
of the Acquired Trust. 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 meetings
or any adjournment thereof. Shareholders of the Reorganized Fund and the
Acquired Trust are entitled to one vote for each share. The Reorganized Fund is
a Maryland corporation and the Acquired Trust is a series of a Delaware business
trust. Under Maryland and 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 Reorganized Fund or the Acquired Trust,
as the case may be: (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.

          The effect of an abstention or broker non-vote by a shareholder of the
Reorganized Fund is the same as a vote against the Fund Plan and the Fund
Reorganization.  Shares of the Acquired Trust with respect to which there is an
abstention or broker non-vote shall be counted for quorum purposes and

                                       2
<PAGE>
 
shall not be treated as "voted" for purposes of determining whether the Trust
Plan and the Trust Reorganization has been approved.  If the enclosed form of
proxy is properly executed and returned in time to be voted at the applicable
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 applicable meeting by written notice to
the Reorganized Fund or the Acquired Trust, as the case may be, 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 applicable Plan and
Reorganization, FOR the other matter or matters specified in the notice of such
meeting 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 Reorganized Fund and the Acquired Trust may
also request brokerage houses, custodians, nominees, and fiduciaries who are
stockholders of record to forward proxy materials to the beneficial owners. D.F.
King & Co. has been retained to assist in the solicitation of proxies at an
estimated cost of $_______ for the Reorganized Fund and $_______ for the
Acquired Trust. The cost of the solicitations will be borne by ______________.

          In the event that sufficient votes to approve a Plan are not received
by the meeting date, the persons named as proxies may propose one or more
adjournments of the applicable meeting to permit further solicitation of
proxies. In determining whether to adjourn a 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 a solicitation.
Any such adjournment will require an affirmative vote by 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 Fund Plan is not approved by the shareholders of the
Reorganized Fund, or if the Fund Reorganization is not consummated for any other
reason, the Reorganized Fund will continue to engage in business as Lord Abbett
California Tax-Free Income Fund, Inc. If the Trust Plan is not approved by the
shareholders of the Acquired Trust, or if the Trust Reorganization is not
consummated for any other reason, the Acquired Trust will continue to engage in
business as California Tax-Free Income Trust, a series of Lord Abbett Securities
Trust. If the Fund Plan is approved by the shareholders of the Reorganized Fund,
and all other conditions to consummation of the Fund Reorganization are
satisfied, the Fund Reorganization will occur regardless of whether the Trust
Plan is approved or the Trust Reorganization is consummated.

FEE TABLE WITH RESPECT TO FUND REORGANIZATION.  Set forth below is a summary
comparison of the expenses of (a) the shares of the Reorganized Fund and (b) on
a pro-forma basis after giving effect to the Fund Reorganization, the Class A
Shares of the Acquiring Fund (to be issued in the Fund Reorganization in

shown in the summary comparison for the shares of the Reorganized Fund are the
actual expenses for the fiscal year ending August 31, 1995, and those shown on a
pro-forma basis for the Class A shares of the Acquiring Fund are such actual
expenses of the Reorganized Fund adjusted for estimated changes in the
management fee and the Rule 12b-1 plan expenses.  The example set forth below is
not a representation of past or future expenses.  Actual expenses may be greater
or less than those shown.

         is referred to as "contingent deferred reimbursement charge" throughout
         this Proxy Statement and Prospectus.
/(2)/    With respect to shares on which the Reorganized Fund's Rule 12b-1
         distribution fee for purchases of $1 million or more has been paid, and
         Class A shares on which the Acquiring Fund's Rule 12b-1 distribution
         fee will be paid, certain redemptions are subject to a contingent
         deferred reimbursement charge of up to 1% if the redemption occurs
         within 24 months after the month of purchase. Holding periods for
         shares purchased prior to the Fund Reorganization will carry over for
         the purpose of determining the applicability of the CDRC to Class A
         shares. See "12b-1 Plans" under "Information About the Reorganizations"
         for a description of the proposed 12b-1 Plan for the A shares.
/(3)/    The expenses of the Acquiring Fund Class A shares are estimated. The
         proposed Rule 12b-1 Plan for the A shares provides for annual service
         fee payments equal to 0.25%, and, if approved by the Board of Trustees,
         distribution fee payments not to exceed in any year 0.25%, of the
         average value of the net assets of the Fund attributable to the Class A
         shares. The board has not authorized the Acquiring Fund to make
         distribution fee payments at this level. The estimated Rule 12b-1 fees
         for the Acquiring Fund Class A shares are based on the distribution fee
         payments authorized by the board. See "12b-1 Plans" under "Information
         About the Reorganizations". Currently, Lord Abbett does not intend to
         waive its management fee for the years subsequent to the Fund
         Reorganization with respect to Class A shares of the Acquiring Fund.
/(4)/    Based on total operating expenses or estimated operating expenses shown
         in the table above.
 
The foregoing is provided to assist shareholders of the Reorganized Fund in
understanding the various expenses the holders of shares of the Reorganized Fund
have incurred and that such holders might incur as holders of the Class A shares
following the Fund Reorganization.

         prior to the Trust Reorganization will carry over for the purpose of
         determining the applicability of the CDRC to Class C shares. See "12b-1
         Plans" under "Information About Reorganizations".
/(4)/    The expenses of the Acquiring Fund Class C shares are estimated. Lord
         Abbett intends to neither waive its management fee nor subsidize
         expenses for the years subsequent to the Trust Reorganization with
         respect to Class C shares of the Acquiring Fund.
/(5)/    Lord Abbett has waived part of its management fee and subsidized
         expenses with respect to the Acquired Trust during the past year (and
         continues to do so). The management fee and other expenses would have
         been 0.50% and 0.24%, respectively, absent such waiver and subsidy.
/(6)/    Based on total operating expenses or estimated operating expenses shown
         in the table above.

The foregoing is provided to assist shareholders of the Acquired Trust in
understanding the various expenses the holders of shares of the Acquired Trust
have incurred and that such holders might incur as holders of the Class C shares
following the Trust Reorganization.

                   ITEM 1. - APPROVAL OF THE AGREEMENTS AND
                            PLANS OF REORGANIZATION

                             SUMMARY OF PROPOSALS

          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 REORGANIZATIONS.  The Plans provide for the transfer to the
Acquiring Fund of all of the assets of the Reorganized Fund and the Acquired
Trust in exchange for Class A shares and Class C shares, respectively, and the
assumption by the Acquiring Fund of all of the liabilities of those respective
Funds.  The Class A shares and Class C shares will then be distributed to the
respective shareholders of the Reorganized Fund and the Acquired Trust and those
Funds will be liquidated.  As a result of the Reorganizations, each shareholder
of the Reorganized Fund and each shareholder of the Acquired Trust will become
an owner of that number of full and fractional Class A shares or Class C shares,
as the case may be, having an aggregate net asset value equal to the aggregate
net asset value of their shares of the Reorganized Fund or the Acquired Trust,
as of the close of business on the date of the Reorganizations.  Consummation of
the Fund Reorganization is subject to the approval of the Reorganized Fund's
shareholders and other conditions.  It is not subject to the consummation of the
Trust Reorganization.  Consummation of the Trust Reorganization is subject to
the approval of the Acquired Trust's shareholders, the prior consummation of the
Fund Reorganization and other conditions.

          To avoid a need to call an Acquiring Fund shareholders' meeting after
the Reorganizations, shareholders of the Reorganized Fund are being asked to
authorize the Reorganized Fund, as the sole Class A shareholder of the Acquiring
Fund before the Fund Reorganization, to (a) approve the proposed distribution
plan for the Class A shares, and (b) approve the investment advisory agreement
for the Acquiring Fund, and shareholders of the Acquired Trust are being asked
to authorize the Acquired Trust, as the sole Class C shareholder of the
Acquiring Fund prior to the Trust Reorganization, to approve the proposed
distribution plan for the Class C shares. A vote in favor of a Reorganization
will be deemed also to be a vote to authorize the Reorganized Fund or the
Acquired Trust, as the case may be, to take such action.

          The directors of the Reorganized Fund believe that it will be
advantageous for the Reorganized Fund to reorganize itself into a series of the
Income Fund rather than to continue as a separate corporation. The directors
believe that this will enable the Reorganized Fund to benefit from
administrative efficiencies resulting from its being a series of a larger
investment company. The trustees of the Acquired Trust believe that the proposed
Trust Reorganization will enable the shareholders of the Acquired Trust to
benefit on a long-term basis from economies of scale while continuing to invest
in a portfolio of securities managed by Lord Abbett under a substantially
similar investment objective. See "Information About the Reorganizations --
Reasons for Reorganizations" for additional information about the reasons for
the Reorganizations.

BUSINESSES OF THE FUNDS.  The Reorganized Fund is a diversified, open-end
management investment company incorporated under the laws of Maryland on May 21,
1985.  It has a single class of shares with

                                       6
<PAGE>
 
equal rights as to voting, dividends, assets and liquidation.   As of December
31, 1995, the Reorganized Fund's net assets were approximately $302 million.

          The Acquired Trust is a non-diversified series of the Securities
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 Securities Trust offers ten series, one of which is the Acquired
Trust, each consisting of one class of shares. The Acquired Trust commenced
investment operations on October 1, 1993. As of December 31, 1995, the Acquired
Trust's net assets were approximately $17 million.

          The Acquiring Fund is a non-diversified series of the Income Fund, an
open-end management investment company incorporated under the laws of Maryland
on December 27, 1983.  Currently, the Income Fund consists of ten series, one of
which is the Acquiring Fund, each consisting of one class of shares.  The
Acquiring Fund will hold no assets and will conduct no investment operations
prior to the consummation of the Fund Reorganization.

INVESTMENT OBJECTIVES AND POLICIES OF THE FUNDS.  The Reorganized Fund and the
Acquired Trust have identical investment objectives: to seek as high a level of
interest income exempt from federal and California personal income tax as is
consistent with preservation of capital.  The objective of the Acquiring Fund is
substantially similar:  to seek as high a level of interest income exempt from
federal and California personal income tax as is consistent with reasonable
risk.

          The Reorganized Fund and the Acquired Trust also have substantially
similar investment policies and restrictions.  The investment policies and
restrictions of the Acquiring Fund have been simplified and made less
restrictive compared to those of the Reorganized Fund and the Acquired Trust 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 Reorganized Fund and the
Acquired Trust are classified as non-fundamental for the Acquiring Fund or made
significantly less restrictive.  See "Comparative Information About the Funds --
Investment Objectives, Policies and Restrictions."

          The portfolios of the Reorganized Fund and the Acquired Trust are
expected to be suitable for the Acquiring Fund, and so no significant
realignment of those portfolios is expected in connection with the
Reorganizations.

PURCHASES AND EXCHANGES.  Shares of the Reorganized Fund and the Acquired Trust
are, and Class A and C Shares will be, available through certain authorized
dealers at the public offering price, which is the net asset value per share
plus, in the case of Class A shares, a one-time sales charge.  Shares of the
Acquired Trust are, and Class C shares will be, subject to a contingent deferred
reimbursement charge equal to 1% of the lower of their cost or the net asset
value if redeemed for cash before the first anniversary of their purchase.  See
"Information About the Reorganizations -- Shares of the Acquiring Fund."
Shareholders of the Reorganized Fund may now exchange their shares for shares of
up to 24 other funds and series in the Lord Abbett family of funds, and
shareholders of the Acquired Trust may now exchange their shares for shares of
the nine other series of the Securities Trust and for shares of Lord Abbett U.S.
Government Securities Money Market Fund, Inc.  It is expected that holders of
Class A shares will be able to exchange their shares for Class A shares of up to
25 other funds and series managed by Lord Abbett and that holders of Class C
shares will be able to exchange their shares for

                                       7
<PAGE>
 
Class C shares of up to 13 of such funds and series.  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 PLANS.  The Reorganized Fund has adopted a plan pursuant to Section
12(b) of the 1940 Act and Rule 12b-1 thereunder (a "Rule 12b-1 Plan"), under
which it pays Lord Abbett (1) an annual service fee (payable quarterly) of 0.25%
of the average daily net asset value of shares sold, or attributable to shares
sold, by dealers and (2) a one-time 1% distribution fee, at the time of sale, on
all shares sold at the $1 million level by dealers, including sales qualifying
at such level under the rights of accumulation and statement of intention
privileges described in the Fund's prospectus in effect at such time, subject to
a contingent deferred reimbursement charge for up to 24 months.  Lord Abbett is
required to pay these service and distribution fees to dealers to provide
additional incentives for the dealers (a) to provide continuing information and
investment services to their shareholder accounts and otherwise to encourage
their accounts to remain invested in the Reorganized Fund and (b) to sell its
shares.

          As part of the Fund Reorganization, the Acquiring Fund is adopting a
new Rule 12b-1 Plan applicable to the Class A shares that will be similar to the
Reorganized Fund's Rule 12b-1 Plan. The principal change is that under the
proposed new Rule 12b-1 Plan for the Class A shares the Board of Directors will
be able to increase the amount of the total distribution fee up to 0.25% of the
Fund's average annual net assets. For a fuller description of the current Rule
12b-1 Plan of the Reorganized Fund and of the proposed new Rule 12b-1 Plan for
the A shares of the Acquiring Fund, see "Information About the Reorganizations
- - --Rule 12b-1 Plans."

          The Acquired Trust has adopted 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 Trust
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 Trust's
Rule 12b-1 Plan, except as noted below under "Information About the
Reorganizations -- Rule 12b-1 Plans."

DIVIDEND POLICIES AND OPTIONS.  The Reorganized Fund and the Acquired Trust
distribute net investment income monthly as dividends.  They also may pay
supplemental dividends and capital gains distributions in December or January.
The Reorganized Fund also pays capital gains distributions in September.  The
shareholders of each such Fund may reinvest such dividends and distributions in
additional shares at net asset value or take such amounts in cash.  The
Acquiring Fund intends to continue these same practices, except that it does not
expect to pay any capital gains distributions in September or January.

REDEMPTION PROCEDURES.   The redemption procedures of the Reorganized Fund and
the Acquired Trust are substantially the same.  The Acquiring Fund will follow
the redemption procedures of the Reorganized Fund, which are described in the
Acquiring Fund Prospectus under "Redemptions."

TAX CONSIDERATIONS.  The consummation of each Reorganization is subject to
receipt of an opinion of counsel substantially to the effect that, among other
things, such Reorganization will not cause a gain or loss to be recognized by
the Reorganized Fund or the Acquired Trust, as the case may be, or its
shareholders for federal income tax purposes.  See "Information about the
Reorganizations--Federal Income Tax Considerations."

                                       8

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 Reorganized Fund and the Acquired Trust 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 Reorganized Fund and the
Acquired Trust.  See "Comparative Information About the Funds -- Investment
Objectives, Policies and Restrictions" below.


                     INFORMATION ABOUT THE REORGANIZATIONS

THE PLANS.  On July 12, 1996, assuming the conditions referred to below are
satisfied, the Reorganized Fund will transfer all of its assets to the Acquiring
Fund (the date of such transfer is referred to herein as the "Closing Date") in
exchange for (i) Class A shares of the Acquiring Fund having an aggregate net
asset value equal to the aggregate value of the assets, less liabilities, of the
Reorganized Fund and (ii) the assumption by the Acquiring Fund of all the
liabilities of the Reorganized Fund.  The Reorganized Fund will distribute as of
the Closing Date such Class A 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 Reorganized Fund.  Approval and consummation of the Trust
Reorganization are not conditions to the consummation of the Fund
Reorganization.  Assuming the other conditions referred to below are satisfied,
the Fund Reorganization will occur regardless of whether the Trust
Reorganization is expected to occur.

          Upon the consummation of the Fund Reorganization and on the Closing
Date, assuming the other conditions referred to below are satisfied, the
Acquired Trust will transfer all of its assets to the Acquiring Fund 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
Trust and (ii) the assumption by the Acquiring Fund of all the liabilities of
the Acquired Trust. The Acquired Trust 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 Trust.

          The net asset values of the Class A shares and Class C shares and the
values of the assets and the amounts of the liabilities of the Reorganized Fund
and the Acquired Trust 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
Reorganized Fund and the Acquired Trust.

          The obligations of each of the Reorganized Fund and the Acquired Trust
to consummate the Reorganization to which it is to be a party are subject to the
satisfaction of certain conditions precedent, including (a) approval and
authorization of each Reorganization by the vote of not less than a majority of
the shares of the Reorganized Fund, outstanding and entitled to vote, or the
vote of a majority of the shares of the Acquired Trust voted in the matter if a
quorum is present, as the case may be, (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"),

                                       9
<PAGE>
 
(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) approved by the shareholders of the Income
Fund of an amendment to its Articles of Incorporation authorizing the creation
of additional classes of shares.

          The foregoing summary of the Plans 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 Plans, copies of which are attached as Exhibits
A(1) and (2).

REASONS FOR THE REORGANIZATIONS.  The Board of Directors of the Reorganized Fund
and the Board of Trustees of the Securities Trust, as well as the Board of
Directors of the Income Fund, including in each case a majority who are not
"interested persons" (as defined in the 1940 Act) of any of the Funds or of Lord
Abbett, approved the respective Plans and Reorganizations on March 14, 1996.  In
this connection, the boards determined that participation in the proposed
Reorganizations is in the best interests of the shareholders of the respective
Funds and that the interests of existing shareholders of the Funds will not be
diluted as a result of their respective Reorganizations.  In doing so, the board
of the Reorganized Fund considered the administrative efficiencies that should
flow to the Reorganized Fund as a result of its being a series of a larger
investment company.  In addition, the boards of the Funds considered several
factors, including that (a) the shareholders of the Acquired Trust are expected
to benefit on a long-term basis from economies of scale as shareholders of the
larger Acquiring Fund following the Reorganizations, 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 imple mented or are seeking to implement
similar distribution arrangements.

          The directors of the Income Fund, the trustees of the Securities Trust
and the directors of the Reorganized 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 (to be received by the
shareholders of the Reorganized Fund in the Fund Reorganization) and Class C
shares (to be received by the shareholders of the Acquired Trust in the Trust
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 various classes and
certain other class specific expenses.  See "Rule 12b-1 Plans" below.

          After the Fund Reorganization, Class A shares will be offered to the
public at net asset value subject to an initial sales charge identical to the
sales charge currently imposed on sales of the Reorganized Fund shares, as
follows:

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

    **    As disclosed in the Acquiring Fund Prospectus, other sales in certain
          categories are made at net asset without a sales charge. 
 
          Subject to some exceptions, Class A shares sold without any sales
charge will be subject to a contingent deferred reimbursement charge (a "CDRC")
of up to 1% of the lower of their cost or their net asset value if they are
redeemed from the Lord Abbett-sponsored family of funds within 24 months after
the month of purchase. See "12b-1 Plans" below. Holding periods for shares
purchased prior to the Fund Reorganization will carry over for the purpose of
determining the applicability of the CDRC to Class A shares.

          After the Trust 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 their purchase, will be subject to a CDRC equal to 1% of
the lower of their cost or then net asset value.  Holding periods for shares
purchased prior to the Trust Reorganization will carry over for the purpose of
determining the applicability of the CDRC to Class C shares.

          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.

          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

                                      11
<PAGE>
 
class or classes.  Shares of the Acquiring Fund will vote together with shares
of other series of Income Fund on all matters affecting the Income Fund, except
for matters, such as approval of an investment management agreement, affecting
only one or more particular series.  All shares voting on a matter will have
identical voting rights.  All issued shares of the Acquiring Fund will be fully
paid and non-assessable, and shareholders will have no preemptive or other right
to subscribe to any additional shares. Shares of all classes of the Acquiring
Fund 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.  Class A Rule 12b-1 Plan.  As part of the Fund Reorganization,
the Acquiring Fund is adopting a Rule 12b-1 plan applicable to the Class A
shares (the "Class A 12b-1 Plan") that will be similar to the plan currently in
effect for the Reorganized Fund.  A copy of the Class A 12b-1 Plan is attached
as Exhibit B to this Proxy Statement and Prospectus. Under the Reorganized
Fund's current plan (except as to certain accounts for which tracking data is
not available), the Fund pays dealers through Lord Abbett (1) an annual service
fee (payable quarterly) of 0.25% of the average daily net asset value of shares
sold, or attributable to shares sold, by dealers and (2) a one-time 1%
distribution fee, at the time of sale, on all shares sold at the $1 million
level by dealers, including sales qualifying at such level under the rights of
accumulation and statement of intention privileges described in the Reorganized
Fund's prospectus in effect at such time. These service and distribution fees
provide additional incentives paid to dealers (a) to provide continuing
information and investment services to their shareholder accounts and otherwise
to encourage their accounts to remain invested in the Reorganized Fund and (b)
to sell shares of the Reorganized Fund.

          Under the current plan of the Reorganized Fund, holders of shares on
which the 1% distribution fee has been paid are required to pay to the
Reorganized Fund a CDRC, or contingent deferred reimbursement charge, of 1% of
the original cost or the then net asset value, whichever is less, of such shares
if they are redeemed out of the Lord Abbett-sponsored family of funds on or
before the end of the twenty-fourth month after the month in which the purchase
occurred. (An exception is made for certain redemptions by tax-qualified plans
under Section 401 of the Internal Revenue Code due to plan loans, hardship
withdrawals, death, retirement or separation from service with respect to plan
participants.) If the shares are exchanged into another Lord Abbett fund and are
thereafter redeemed out of the Lord Abbett family on or before the end of such
twenty-fourth month, the charge is collected for the Reorganized Fund by the
other fund. The Reorganized Fund collects such a charge for other Lord Abbett-
sponsored funds in a similar situation.

          Set forth below is a description of the principal changes to be
effected under the proposed Class A 12b-1 Plan:

          (a) Distribution Fees.  The Board of Directors of the Income Fund will
              -----------------  
be authorized under the Class A 12b-1 Plan, without further shareholder vote, to
increase the amount of distribution fees up to 0.25% of the average annual net
assets attributable to the Class A shares. This increased spending limit is
intended primarily to permit the trustees to increase the amount to be spent for
distribution to meet changing sales competition. The directors believe it is
desirable to be able to make these changes without further shareholder approval
because additional shareholder meetings would be costly to the Acquiring Fund
and its shareholders and the time required for such meetings could delay the
implementation of advantageous changes. The Board of Directors will approve
additional charges under

                                      12
<PAGE>
 
this increased authority only if a majority of the directors who are not
"interested persons" of the Income Fund within the meaning of the 1940 Act and
who will have no direct or indirect financial interest in the operations of the
Class A 12b-1 Plan or in any agreements related thereto conclude in their
business judgment that there is a reasonable likelihood that the increase will
benefit the Acquiring Fund and its shareholders.

          The one-time 1% distribution fee, payable at the time of certain sales
as described above, is to be charged against the 0.25% permitted annual
distribution fee. During the Reorganized Fund's last fiscal year, payments of
the one-time 1% distribution fee under that Fund's Rule 12b-1 plan totaled 0.__%
of the Reorganized Fund's average net assets. Subject to approval of the Fund
Reorganization by the shareholders of the Reorganized Fund, the Board of
Directors of the Income Fund has authorized the Acquiring Fund to pay this one-
time distribution fee with respect to sales of Class A shares, subject to three
changes: First, the payments will be made in connection with sales to
         -----                                                       
retirement plans with 100 or more eligible employees, in addition to sales at
the $1 million level as under the Reorganized Fund's 12b-1 plan; Second, the
                                                                 ------     
payments will be reduced as follows:  1.0% of the first $5 million, 0.55% of the
next $5 million, 0.50% of the next $40 million and 0.25% over $50 million of
shares sold to a retirement plan or other qualifying purchaser within a 12-month
period (beginning when the first purchase is made at net asset value); and
Third, the payments will be made to institutions and persons permitted by
- - -----                                                                    
applicable law and/or rules to receive such payments ("Authorized
Institutions"), rather than just to dealers as is the case under the Reorganized
Fund's Rule 12b-1 plan.

          Subject to such approval of the Fund Reorganization, the Income Fund's
Board of Directors has authorized the Acquiring Fund to pay, as an additional
distribution fee, a modest supplemental payment to dealers who have accounts
comprising a significant percentage of the Acquiring Fund's Class A share
assets, having a lower than average redemption rate and who have a satisfactory
program for the promotion of Class A shares.  Any such payments will be 0.10%
per annum of the average assets of the Acquiring Fund represented by the Class A
share accounts of qualifying dealers.  This supplemental payment is intended by
the Board of Directors to enhance the Acquiring Fund's relationships with those
dealers most likely to have a significant impact on the growth of the Class A
shares.

          (b) Service Fees.  Service fee payments, which are to be continued
              ------------   
under the proposed Class A 12b-1 Plan at an annual rate of 0.25% of the average
daily net asset value of the Class A shares could be made to all Authorized
Institutions (institutions and persons permitted by applicable law and/or rules
to receive such payments), rather than just to dealers as is the case under the
Reorganized Fund's plan.

          (c) Use of Payments by Lord Abbett.  Lord Abbett will be permitted to
              ------------------------------
use payments received under the Class A 12b-1 Plan to provide continuing
services to shareholder accounts not serviced by Authorized Institutions and,
with board approval, to finance any activity which is primarily intended to
result in the sale of Class A shares. Any such payments to finance activities
primarily intended to result in the sale of Class A shares would be subject to
the overall ceiling of 0.25% for annual distribution fees.

          (d) CDRC.  The Board of Directors of the Income Fund has approved a
              ----
CDRC applicable to the Class A 12b-1 shares substantially similar to the CDRC
payable under the Rule 12b-1 Plan of the Reorganized Fund, except that no CDRC
would be payable in connection with redemptions by retirement plans (not just
those qualified under Section 401 of the Internal Revenue Code) attributable to
any benefit

                                      13
<PAGE>
 
payment or distribution of any excess contribution thereunder (not just those
described above in connection with such exception under the Reorganized Fund's
plan).  Because CDRC payments will be made directly to the Acquiring Fund, they
will have the effect of reducing the amount of the distribution fees paid by the
Acquiring Fund for the purpose of complying with the overall ceiling of 0.25%
for annual distribution fees.  As in the case of the specific distribution fees
authorized by the Board of Directors of the Income Fund, the CDRC authorized
from time to time by the board for the Class A shares will be described in the
then current prospectus of the Income Fund.

          If the supplemental payment to dealers, the revised one-time
distribution fee and the other changes described above had been in effect for
the Reorganized Fund's last fiscal year, it is estimated that, in the aggregate,
they would have increased the expense ratio of the Reorganized Fund from 0.__%
to approximately 0.__%, a difference of 0.__%.

          (e) Lord Abbett Distributor.  The other party to the Class A 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. Lord Abbett Distributor is to take on all the underwriting
functions currently performed directly by Lord Abbett.

          The Class A 12b-1 Plan was approved on March 14, 1996 by the directors
of the Income Fund, including a majority of the directors who are not
"interested persons" of the Income Fund within the meaning of the 1940 Act and
who will have no direct or indirect financial interest in the operations of the
Class A 12b-1 Plan or in any agreements related thereto. In considering whether
to approve the Class A 12b-1 Plan, the directors considered, among other things,
the factors set forth below:

          (i)  Flexibility in Adapting Distribution Fees to Meet Industry-Wide
               ---------------------------------------------------------------
     Changes.  During the last several years, there has been significantly
     -------                                                              
     increased competition and pricing experimentation in the mutual fund
     industry. As the pace of change increases, the Board of Directors believes
     it will be useful to be able to respond more quickly to marketplace
     pressures, and to change in appropriate cases the amount of the 
     Class A 12b-1 distribution fees to be paid, without unnecessarily burdening
     the shareholders with the costs of additional proxy solicitations. The
     directors believe that the increased distribution fees described above are
     good examples of the desirability of this flexibility. Based on advice
     received from Lord Abbett, the decision by the board to approve the payment
     of distribution fees in connection with sales to retirement plans with 100
     or more eligible employees will enable the Class A shares to compete more
     effectively in this growing and important market. The 0.10% per annum
     supplemental payments to dealers who meet certain criteria will permit the
     Acquiring Fund to enhance relationships with those dealers most likely to
     have a significant impact on the growth of the Class A shares.

         (ii)  Expanding Categories of Persons Eligible to Receive Payments. The
               ------------------------------------------------------------
     current Rule 12b-1 Plan of the Reorganized Fund limits payments thereunder
     to dealers selling fund shares. Since that plan was adopted, different
     methods of distribution, using different entities, have developed in the
     industry. The Board of Directors sees no reason to limit arbitrarily the
     categories of persons eligible to receive payments under the proposed plan,
     and believes that the availability of payments under the plan will induce
     such other entities to invest in Class A shares.

                                      14
<PAGE>
 
        (iii)  Flexibility in Distributor's Use of Payments.  Lord Abbett has
               --------------------------------------------                  
     advised the Board of Directors that allowing Lord Abbett Distributor to
     retain fees received from the Fund to (i) provide continuing information
     and investment services to shareholder accounts and (ii) finance, with
     board approval, any activity which is primarily intended to result in the
     sale of Class A shares will provide useful flexibility and will be in line
     with common practice in the industry.

          Prior to the Fund Reorganization, the Reorganized Fund will purchase
one Class A share, and as sole shareholder of the Acquiring Fund, will approve
the Class A 12b-1 Plan prior to the class being issued to the Reorganized Fund
in the Fund Reorganization. A vote in favor of the Fund Reorganization will be
deemed also to be a vote to authorize the Reorganized Fund to take such action.

          Class C Rule 12b-1 Plan. 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 Trust. The Acquired Trust'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 Trust Prospectus under "Purchases" for additional
information concerning the Rule 12b-1 Plan of the Acquired Trust.

          There are two substantive changes in the Class C 12b-1 Plan:  First,
                                                                        ----- 
payment under the plan may be made to all Authorized Institutions (institutions
and persons permitted by applicable law and/or rules to receive such payments),
rather than just to dealers, as is the case under the Acquired Trust's Rule 12b-
1 plan; and Second, the other party to the Class C 12b-1 Plan is to be Lord
            ------                                                         
Abbett Distributor (a New York limited liability company to be formed as a
subsidiary of Lord Abbett), rather than Lord Abbett itself.  Lord Abbett
Distributor will take on all the underwriting functions currently performed
directly by Lord Abbett.

          The Class C 12b-1 Plan was approved on March 14, 1996 by the directors
of the Income Fund, including a majority of the trustees who are not "interested
persons" of the Income 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 Trust Reorganization, the Acquired
Trust 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 Trust in the
Trust Reorganization. A vote in favor of the Trust Reorganization will be deemed
also to be a vote to authorize the Acquiring Trust to take such action.

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

                                      15
<PAGE>
 
          (a)  no gain or loss will be recognized by the Reorganized Fund or the
     Acquired Trust, as the case may be, upon the transfer of its assets to the
     Acquiring Fund in exchange for Class A shares or Class C shares, as the
     case may be, and the assumption by the Acquiring Fund of its liabilities or
     upon the distribution of the Class A shares or the Class C shares, as the
     case may be, to its shareholders;

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

          (c)  no gain or loss will be recognized by shareholders of the
     Reorganized Fund or the Acquired Trust, as the case may be, upon the
     exchange of their shares for Class A shares or Class C shares;

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

          (e)  the tax basis of the assets of the Reorganized Fund or the
     Acquired Trust acquired by the Acquiring Fund will be the same as the tax
     basis of such assets to the Reorganized Fund or the Acquired Trust, as the
     case may be, immediately prior to the Reorganizations, and the holding
     period of such assets in the hands of the Acquiring Fund will include the
     period during which those assets were held by the Reorganized Fund or the
     Acquired Trust, as the case may be.

          The Funds have not sought a tax ruling from the Internal Revenue
Service with respect to the tax consequences of the Reorganizations, 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 Reorganizations, shareholders
should also consult their tax advisors as to any state or local tax consequences
of the Reorganizations to them and any special considerations that may apply in
their individual circumstances.

EXPENSES OF THE REORGANIZATIONS.  Expenses of the Reorganizations, 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 Reorganizations are consummated, the respective expenses of the
Reorganized Fund and the Acquired Trust, 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 those Funds for the purpose of calculating the
numbers of Class A and Class C shares to be issued in the Reorganizations.

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

</TABLE>

          The exchange ratio of Class A shares for Reorganized Fund shares is to
be one for one. The foregoing table reflects a pro-forma exchange ratio of
approximately 0.4 Class C shares for each Acquired Trust share. If the Trust
Reorganization is consummated, the actual exchange ratio of Class C and Acquired
Trust shares may vary from this pro-forma ratio due to changes in the market
value of the portfolio securities of both the Reorganized Fund and the Acquired
Trust between December 31, 1995 and the Closing Date, and changes in the amounts
of undistributed net investment income and accrued liabilities of the
Reorganized Fund and the Acquired Trust during that period.


                    COMPARATIVE INFORMATION ABOUT THE FUNDS

MANAGEMENT AGREEMENTS. Upon consummation of the Reorganizations, an investment
management agreement between the Acquiring Fund and Lord Abbett will become
effective with terms that are substantially the same as those currently in
effect between the Reorganized Fund and Lord Abbett and between the Acquired
Fund and Lord Abbett.  The Reorganized Fund's ratio of management fee expenses
to average net assets for the year ended August 31, 1995 was 0.40%.  The
Acquired Trust's ratio of management fee expenses to average net assets for the
year ended October 31, 1995 was 0.0%.  This fee rate reflects a waiver of
management fees.  The management agreement provides for the Acquired Trust to
repay Lord Abbett without interest for any expenses of the Acquired Trust paid
or reimbursed by Lord Abbett, as follows: if the Acquired Trust's annual expense
ratio (determined before taking into account any fee waiver or expense payment
or reimbursement by Lord Abbett) is less than 1.95% after the first day of the
calendar quarter after the net assets of the Acquired Trust first reach $50
million (the "commencement date"), the Acquired Trust will repay Lord Abbett an
amount sufficient to increase the expense ratio to 1.95%.  The Acquired Trust is
not obligated to repay any such expenses after the earlier of the termination of
the management agreement or the end of five full fiscal years after the commence
ment date.  The contingent obligation to repay such expenses, which totaled
$88,271 as of December 31, 1995, will be extinguished upon the consummation of
the Reorganization.  A vote in favor of the Fund Reorganization by a shareholder
of the Reorganized Fund will be deemed also to be a vote to authorize the
Reorganized Fund to approve the new investment management agreement between the
Acquiring Fund and Lord Abbett.  (See "Meetings of Shareholders of the
Reorganized Fund and the Securities Trust.")

FEES AND EXPENSES.  As shown above under "Fee Tables," the pro-forma expense
ratios of the Class C Shares for the year ended October 31, 1995, calculated as
if the Reorganizations had occurred at the beginning of such year, was 1.53%,
compared to 0.93% for the Acquired Trust. If Lord Abbett had not waived its
management fee and subsidized expenses for the Acquired Trust, the Acquired
Trust's expense

                                      17
<PAGE>
 
ratio for such year would have been 1.67%.  The pro forma expense ratio of the
Class A shares for the year ended August 31, 1995, calculated as if the
Reorganizations had occurred at the beginning of such year, was 0.87%, compared
to 0.76% for the Reorganized Fund.

INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS.  The Reorganized Fund and the
Acquired Trust have identical investment objectives:  to seek as high a level of
interest income exempt from federal and California personal income tax as is
consistent with preservation of capital.  The Acquiring Fund currently has the
same investment objective but is seeking shareholder approval of the following
amended objective:  to seek as high a level of interest income exempt from
federal and California personal income tax as is consistent with reasonable
risk.  The Reorganized Fund and the Acquired Fund seek their objectives by
investing primarily in intermediate- and long-term municipal bonds.  See the
Acquiring Fund Prospectus under "How We Invest" for a description of U.S.
Government securities.

          The Reorganized Fund and the Acquired Trust also have substantially
the same investment policies and restrictions. The investment policies and
restrictions of the Acquiring Fund, compared to those of the Reorganized Fund
and the Acquired Trust, have been simplified and made less restrictive in order
to provide greater flexibility in managing the investment portfolio of the
Acquiring Fund. A number of the investment policies and restrictions that are
classified as fundamental for the Reorganized Fund and the Acquired Trust are
classified as non-fundamental for the Acquiring Fund. In other instances,
certain fundamental restrictions of the Reorganized Fund and the Acquired Trust
have been modified or eliminated in the case of the Acquiring Fund. Fundamental
investment restrictions may not be changed without approval of the stockholders
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
stockholders, 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
either or both of the Reorganized Fund and the Acquired Trust: (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, borrowings of an additional 5% of total assets for temporary purposes
and such short-term credits as may be necessary for the clearance of purchases
and sales of portfolio securities; (iii) loans of portfolio securities in
accordance with applicable law; (iv) 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; (v) investments of more than 10% (up to 15%) of assets in restricted
securities; (vi) pledges to secure borrowings or in connection with hedging
transactions and other investment strategies; (vii) investments in the
securities of other investment companies; and (viii) purchases and sales of put,
call, straddle or spread options. Currently, the Acquiring Fund does not intend
to take all such action, but the Board of Directors of the Income 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 investment policies and restrictions of
the Acquiring Fund, the Reorganized Fund and the Acquired Trust is set forth in
Exhibit C to this Proxy Statement and Prospectus. For a full discussion of the
Acquiring Fund's investment objectives, policies and restrictions, see
"Investment Objective" and "How We Invest" in the Acquiring Fund Prospectus and

Additional Information. For a

Reorganized Fund and the Acquired Trust, see "Investment Objective" and "How We
Invest" in the Reorganized Fund Prospectus and the Acquired Trust Prospectus,
respectively, and "Investment Objective and Policies" in the Reorganized Fund
Statement of Additional Information and Acquired Trust Statement of Additional
Information, respectively.  The summary comparison set forth in Exhibit C 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 shareholders of the Reorganized Fund
and the Acquired Trust will not change in an adverse way as a result of the
Reorganizations.  After the Reorganizations, the rights of the former
shareholders of the Reorganized Trust and the Acquired Trust will be governed by
the Income Fund's Articles of Incorporation, By-Laws and applicable Maryland
law.  Prior to the Fund Reorganization, the rights of the shareholders of the
Reorganized Fund are governed by the Articles of Incorporation and By-Laws of
the Reorganized Fund and applicable Maryland law.  Prior to the Trust
Reorganization, the rights of the shareholders of the Acquired Trust are
governed by the Declaration of Trust and By-Laws of the Securities Trust 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 Reorganized Fund and Board of
Trustees of the Acquired Trust are comprised of the same individuals as the
current Board of Directors of the Income Fund.  The responsibilities and
fiduciary duties of the directors of the Acquiring Fund are substantially the
same as those of the directors of the Reorganized Fund and the trustees of the
Acquired Trust.  The Acquiring Fund's and the Reorganized Fund's By-Laws provide
for indemnification of the directors for actual liabilities arising out of their
service in their capacity as directors, subject only to the conditions and
limitations of applicable law.  The Securities Trust's Declaration of Trust
provides for indemnification of the trustees against certain liabilities and
expenses, except with respect to (i) any matter as to which any trustee has been
adjudicated not to have acted in good faith in the reasonable belief that his or
her action was in the best interest of such Trust, (ii) any liability by reason
of willful misfeasance, bad faith, gross negligence or reckless disregard of
duties or (iii) any matter disposed of by settlement, compromise or consent
decree, unless it is in the best interests of such trust or if said trustee
acted in good faith in the reasonable belief that such act was in the best
interests of the trust.  Income Fund and Reorganized Fund shareholders may
remove, with or without cause, any director by the affirmative vote of a
majority of the votes cast.  Securities Trust shareholders may remove a trustee
by the vote of shareholders of record of not less than two-thirds.

          Neither the Reorganized Fund, the Acquired Trust nor the Income Fund
regularly holds shareholder meetings.  The By-laws of each of the 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 Reorganized Fund and the Acquired Trust and of the rights these
shareholders will have following the Reorganizations as holders of Class A
shares and Class C shares of the Acquiring Fund. It is not a complete
description of the Articles of Incorporation of the Income Fund and the

          The Board of Directors of the Reorganized Fund recommends that
shareholders of the Reorganized Fund vote FOR approval of the Fund Plan and the

recommends that shareholders of the Acquired Trust vote FOR approval of the

ITEM 2. -  FOR REORGANIZED FUND SHAREHOLDERS ONLY

          The Board of Directors of the Reorganized Fund believes that it is
important to ensure continuity of operation of the Reorganized Fund in the event
that the Fund Reorganization is not consummated.  Accordingly, the Board has
determined that: (i) the persons who currently constitute the Board of Directors
of the Reorganized Fund should stand for re-election, for a term of office to
extend until their successors are elected and qualified, and (ii) the selection
of Deloitte & Touche LLP as the independent public accountants of the
Reorganized Fund should be submitted to shareholders for ratification, as
required by the 1940 Act if the Reorganized Fund continues to engage in business
as an investment company.

               A. ELECTION OF DIRECTORS OF THE REORGANIZED FUND

          The nominees for election as directors of the Reorganized Fund are
Ronald P. Lynch, Robert S. Dow, E. Thayer Bigelow, Stewart S. Dixon, John C.
Jansing, C. Alan MacDonald, Hansel B. Millican, Jr. and Thomas J. Neff, who have
been nominated by the Board of Directors to succeed themselves. The individuals
named as proxies intend to vote the proxies, unless otherwise directed, in favor
of the election of such nominees, each of whom has agreed to continue to serve
as a director of the Reorganized Fund. Management of the Reorganized Fund has no
reason to believe that any nominee will be unable to serve as a director. If any
nominee should be unable to serve as a director, it is the intention of the
individuals named as proxies to vote for the election of such person or persons
as the Board of Directors may, in its discretion, recommend.

          Information about each person nominated for election as a director is
set forth in the following table. Except where indicated, each of the persons
listed in the table has held the principal occupation listed opposite his name
for the past five years.

principles and practices and other matters when requested from time to time by
the directors who are not "interested persons" of the Reorganized Fund within

fiscal year of the Reorganized Fund ended August 31, 1995.

          The Board of Directors of the Reorganized Fund met [eleven] times
during the fiscal year ended August 31, 1995, and each director attended at

(1)  Fees for directors not associated with Lord Abbett, including attendance
     fees for board and committee meetings, are allocated among all Lord Abbett-
     sponsored funds based on net assets of each fund. Fees payable by the
     Reorganized Fund to such directors are being deferred under a plan that
     deems the deferred amounts to be invested in shares of the Reorganized Fund
     for later payment to the directors. The total amount accrued under the plan
     for each such director since the beginning of his tenure with the
     Reorganized Fund, including dividends reinvested and changes in net asset
     value applicable to such deemed investments, were as follows as of August
     31, 1995: Mr. Bigelow, $876; Mr. Dixon, $20,872; Mr. Jansing, $21,669; Mr.
     MacDonald, $9,464; Mr. Millican, $21,645; and Mr. Neff, $20,872.

(2)  Each Lord Abbett-sponsored fund has a retirement plan providing that
     Directors not associated with Lord Abbett will receive annual retirement
     benefits for life equal to 80% of their final annual retainers following
     retirement at or after age 72 with at least 10 years of service. Each plan
     also provides for a reduced benefit upon early retirement under certain
     circumstances, a pre-retirement death benefit and actuarially reduced 
     joint-and-survivor spousal benefits. The amounts stated in column (IV)
     would be payable annually under such retirement plans if the director were
     to retire at age 72 and the annual retainers payable by such funds were the
     same as they are today. The amounts set forth in column (III) were

                                      23

     accrued by the Lord Abbett-sponsored funds during the fiscal year ended
     August 31, 1995 with respect to the retirement benefits set forth in column
     (IV).

(3)  This column shows aggregate fees of directors who are not "interested
     persons" of the Reorganized Fund within the meaning of the 1940 Act,
     including attendance fees for board and committee meetings, of a nature
     referred to in the first sentence of footnote (1), accrued by the Lord
     Abbett-sponsored funds during the year ended December 31, 1995.

(4)  Mr. Bigelow was elected a director of the Fund on October 19, 1994.

(5)  Mr. Creamer retired as a director of the Fund effective September 21, 1994.

                        INDEPENDENT PUBLIC ACCOUNTANTS

          The Board of Directors of the Reorganized Fund has selected Deloitte &
Touche LLP as the independent public accountants of the Reorganized Fund for the
fiscal year ending August 31, 1996.  The 1940 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 Reorganized Fund's independent public accountants for the
year ended August 31, 1995, and for a number of years prior thereto.  Based on
information in the possession of the Reorganized Fund, and information furnished
by Deloitte & Touche LLP, such firm has no direct financial interest and no
material indirect financial interest in the Reorganized Fund.  A representative
of Deloitte & Touche LLP is expected to attend the meeting and will be provided
with an opportunity to make a statement and answer appropriate questions.  The
Board of Directors' recommendation of Deloitte & Touche LLP has been made so
that such firm may continue to serve as the independent public accountants of
the Reorganized Fund in the event that the Fund Reorganization does not occur
for any reason.

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

          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 Acquired Fund will
transfer its assets 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 A Shares, including fractional Acquiring Fund
Class A Shares, equal to the number of the shares of capital stock of the
Acquired Fund as of the close of regular trading on the New York Stock Exchange
(the "NYSE") on the Closing Date (such time and date being hereinafter called
the "Valuation Date"); and (ii) to assume 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 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 

                                       2
<PAGE>
 
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 A 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 same number of full and fractional Acquiring Fund Class A
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 A
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 A 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 liquidated pursuant to the law
of Maryland.  Any reporting responsibility of the Acquired Fund is and shall
remain the responsibility of the Acquired Fund up to and including the Closing
Date and following the liquidation 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 

                                       3
<PAGE>
 
on the Valuation Date, using the valuation procedures set forth in the Articles
of Incorporation of the Income Fund.

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

3.   CLOSING AND CLOSING DATE

     3.1.  The Closing Date shall be July 12, 1996, or such other date as the
parties may agree to in writing.  All acts taking place at the Closing shall be
deemed to take place simultaneously as of the close of business on the Closing
Date unless otherwise provided.  The Closing shall be held as of 5:00 p.m. at
the offices of [specify location in New Jersey], or at such other time and/or
place as the parties may agree.

     3.2.  In the event that on the Valuation Date (a) the NYSE or another
                                                    -

Acquired Fund shall be closed to trading or trading thereon shall be restricted
or (b) trading or the reporting of trading on the NYSE or elsewhere shall be

disrupted so that accurate appraisal of the value of the net assets of the
Acquiring Fund or the Acquired Fund is impracticable, the Closing Date shall be
postponed until the first business day after the day when trading shall have
been fully resumed and reporting shall have been restored.

     3.3.  At the Closing, the Acquired Fund shall direct its custodian to
deliver to the custodian of the Acquiring Fund, for the Acquiring Fund's
account, all of its portfolio securities and other assets held by such custodian
for the Acquired Fund's account, duly endorsed in proper form for transfer as
appropriate, in such condition as to constitute good delivery thereof in
accordance with the custom of the Acquiring Fund's custodian, and shall be
accompanied by all necessary federal and state stock transfer stamps or a check
for the appropriate purchase price thereof.

     3.4.  The Acquired Fund shall direct its transfer agent to deliver to the
transfer agent of the Acquiring Fund on the Closing Date a list of the names and
addresses of the Acquired Fund's shareholders and the number of outstanding
shares owned by each such shareholder immediately prior to the Closing.  The
Acquiring Fund shall direct its transfer agent to issue and deliver a
confirmation evidencing the Acquiring Fund Class A Shares to be credited to the
Acquired Fund's account on the Closing Date to the transfer agent of the
Acquired Fund, or provide evidence satisfactory to the Acquired Fund that such
Acquiring Fund Class A Shares have been credited to the Acquired Fund's account
on the books of the Acquiring Fund.  At the Closing, each 

                                       4

party shall deliver to the other such bills of sale, checks, assignments, share
certificates, if any, receipts, assumption agreements or other documents as
such other party or its counsel may reasonably request.

     liabilities or business other than changes occurring in the ordinary course
     of business, or any incurrence by the Income Fund's of indebtedness
     maturing more than one year from the date such indebtedness was incurred,
     except as otherwise disclosed to and accepted by the Acquired Fund.

            (i)  At the Closing Date, all federal and other tax returns and
     reports of the Income 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 and reports shall have been paid, or provision shall
     have been made for the payment thereof, and to the best of the Income
     Fund'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 Income

     Fund, nor is there outstanding any security convertible into shares of the
     Acquiring Fund.

     been duly authorized by all necessary action on the part of the Income
     Fund's Board of Directors, and assuming due authorization, execution and
     delivery by the Acquired Fund, this Agreement constitutes a valid and
     binding obligation of the Income Fund on behalf of the Acquiring Fund,
     enforceable in accordance with its terms, subject as to enforcement to
     bankruptcy, insolvency, reorganization, moratorium and other laws relating
     to or affecting creditors' rights and to general equity principles.

            (m)  The N-14 Registration Statement (except insofar as it relates
     to the Acquired Fund or the special meeting of its shareholders referred to
     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
     made, not materially misleading.

            (n)  The Acquiring Fund Class A Shares to be issued and delivered to
     the Acquired Fund pursuant to the terms of this Agreement have been duly
     authorized by the Income Fund's Board of Directors on behalf of the
     Acquiring Fund, and when issued and delivered at the Closing in accordance
     with

     Shares and will be fully paid and non-assessable with no personal liability

                     AGREEMENT AND PLAN OF REORGANIZATION

          THIS AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made as

reorganization and liquidation within the meaning of Section 368(a)(1)(C) and
(F) of the United States Internal Revenue Code of 1986, as amended (the "Code");

          WHEREAS, the reorganization (the "Reorganization") will consist of the
transfer of all of the assets of the Acquired Fund in exchange for Class C

          WHEREAS, the Acquiring Fund is authorized to issue a single class of

and certain other expenses;

          WHEREAS, after the multiple class share structure is authorized by the

          WHEREAS, the Board of Directors, including a majority of the directors

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 Securities
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

                                       2
<PAGE>
 
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 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

     is a party or by which it is bound.

          (e)  The Securities Trust has no material contracts or other

     Fund's properties or assets, which if adversely determined would materially
     and adversely affect the financial condition of the Acquired Fund or the

     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 Securities
     Trust to consummate the transactions contemplated herein.

          (g)  True and correct copies of the Acquired Fund's (i) Statement of
                                                               -

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

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

          (i)  The Securities Trust will file the final federal and other tax

     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 Securities
     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

     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

     shares of the Acquired Fund, nor is there outstanding any security
     convertible into any shares of the Acquired Fund.

     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

                                       7

     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 Securities
     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 Securities Trust on behalf of the Acquired Fund, enforceable in
     accordance with its terms, subject as to enforcement to bankruptcy,
     insolvency, reorganization, moratorium and other laws relating to or
     affecting creditors' rights and to general equity principles.  The
     Securities Trust's Board of Trustees has called a meeting of the Securities
     Trust 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 Securities
     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 Securities 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.

     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

     condition and the operations and changes in net assets of the Income Fund
     as of such date and for such period, respectively.  There are no known

     treatment as a regulated investment company and the Acquiring Fund intends
     to do so in the future.

     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

                                       15
<PAGE>
 
          (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

     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

                                                                       EXHIBIT B

                  Rule 12b-1 Distribution Plan and Agreement
 Lord Abbett Tax-Free Income Fund, Inc. -- California Series -- Class A Shares
 -----------------------------------------------------------------------------


          RULE 12b-1 DISTRIBUTION PLAN AND AGREEMENT dated as of July 12, 1996
by and between LORD ABBETT TAX-FREE INCOME FUND, INC., a Maryland corporation
(the "Fund"), on behalf of its CALIFORNIA SERIES (the "Series"), and LORD ABBETT
DISTRIBUTOR LLC, a New York limited liability company (the "Distributor").

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

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

          WHEREAS, the Fund's Board of Directors has determined that there is a
reasonable likelihood that the Plan will benefit the Series 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 Series in order to provide additional
incentives to such Authorized Institutions (i) to sell Shares and (ii) to
                                            -                      --
provide continuing information and investment services to their accounts holding
Shares and otherwise to encourage their accounts to remain invested in the
Shares.

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

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

          4.  The net asset value of the Shares shall be determined as provided
in the Articles of Incorporation of the Fund. If the Distributor waives all or a
portion of the fees which are to be paid by the Series hereunder, the
Distributor shall not be deemed to have waived its rights under this Agreement
to have the Series 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 Series hereunder and shall provide to the Fund's Board of
Directors, and the Directors shall review at least quarterly, a written report
of the amounts so expended pursuant to this Plan and the purposes for which such
expenditures were made.

                                       2
<PAGE>

          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 may otherwise be provided
in the Act.

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

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

          9.  This Plan may not be amended to increase materially the amount to
be spent by the Series hereunder above the maximum amounts referred to in
paragraph 3 of this Plan without a shareholder vote in compliance with Rule 12b-
1 and Rule 18f-3 under the Act as in effect at such time, and each material
amendment must be approved by a vote of the Board of Directors of the Fund,
including the vote of a majority of the directors who are not "interested
persons" of the Fund and who have no direct or indirect financial interest in
the operation of this Plan or in any agreement related to this Plan, cast in
person at a meeting called for the purpose of voting on such amendment.
Amendments to this Plan which do not increase materially the amount to be spent
by the Series hereunder above the maximum amounts referred to in paragraph 3 of
this Plan may be made pursuant to paragraph 10 of this Plan.

          10.  Amendments to this Plan other than material amendments of the
kind referred to in the forgoing paragraph 9 may be adopted by a vote of the
Board of Directors of the Fund, including the vote of a majority of the
directors who are not

                                       3
<PAGE>
 
"interested persons" of the Fund and who have no direct or indirect financial
interest in the operation of this Plan or in any agreement related to this Plan.
The Board of Directors of the Fund may, by such a vote, interpret this Plan and
make all determinations necessary or advisable for its administration.

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

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

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

                                    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
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 or 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

                                      C-1
<PAGE>
 
majority of a quorum of the non-interested, non-party directors of Registrant,
or an independent legal counsel in a written opinion, shall determine, based on
a review of readily available facts, that there is reason to believe that the
indemnitee ultimately will be found entitled to indemnification.

          Insofar as indemnification for liability arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expense
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

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

                    LORD ABBETT TAX-FREE INCOME FUND, INC.

                             ARTICLES OF AMENDMENT


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

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

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

               "SECTION 1.  The total number of shares which the Corporation has
          authority to issue is 1,000,000,000 shares of capital stock of the par
          value of $.001 each (the "Shares"), having an aggregate par value of
          $1,000,000.  The Board of Directors of the Corporation shall have full
          power and authority, from time to time, to classify or reclassify any
          unissued Shares, including, without limitation, the power to classify
          or reclassify unissued shares into series, and to classify or
          reclassify a series into one or more classes of stock that may be
          invested together in the common investment portfolio in which the
          series is invested, by setting or changing the preferences, conversion
          or other rights, voting powers, restrictions, limitations as to
          dividends, qualifications, or terms or conditions of redemption of
          such shares of stock.  All Shares of a series shall represent the same
          interest in the Corporation and have the same preferences, conversion
          or other rights, voting powers, restrictions, limitations as to
          dividends, qualifications, and terms and conditions of redemption as
          the other Shares of that series, except to the extent that the Board
          of Directors provides for differing preferences, conversion or other
          rights, voting powers, restrictions, limitations as to dividends,
          qualifications, or terms or conditions of redemption of Shares of
          classes of such series as determined pursuant to Articles
          Supplementary filed for record with the State Department of
          Assessments and Taxation of Maryland, as otherwise determined pursuant
          to these Articles or by the Board of Directors in accordance with law.
          The Shares shall initially be classified into nine series designated
          initially as the "National Series", consisting of 80,000,000 Shares,
          the "Connecticut Series", consisting of 40,000,000 Shares, the "Hawaii
          Series", consisting of 40,000,000

                    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.

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

                    deems fair and equitable; and any Unallocated Items so
                    allocated and charged to a particular series shall belong to
                    that series. Each such allocation by the Board of Directors
                    shall be conclusive and binding upon the stock holders of
                    all series for all purposes. To the extent determined by the
                    Board of Directors, liabilities and expenses relating solely
                    to a particular class (including, without limitation,
                    distribution expenses under a Rule 12b-1 plan and
                    administrative expenses under an administration or service
                    agreement, plan or other arrangement, however designated,
                    which may be adopted for such class) shall be allocated to
                    and borne by such class and shall be appropriately reflected
                    (in the manner determined by the Board of Directors) in the
                    net asset value, dividends and distributions and liquidation
                    rights of the shares of such class.

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

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

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

               (e)  Voting. On each matter submitted to vote of the 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.

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

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

                                       5
<PAGE>
 
                    stockholder elections to receive dividends or distributions
                    in cash or Shares or that may otherwise exist with respect
                    to dividends and distributions on Shares of the same
                    series."

          (c)  Striking out the phrase "of any Class" or "and of any Class", as
     the case may be (including any punctuation with respect thereto), from the
     preamble and subsections (a), (b) and (c) of Section 3 of Article V and
     Sections 1(c) and 2 of Article VII.

          (d)  Striking out the last sentence of Section 3(a) of Article V and
     inserting in lieu thereof:

          "Each holder of the Shares, upon request to the Corporation
          accompanied by surrender (to the Corporation, or an agent designated
          by it) of the appropriate stock certificate or certificates, if any,
          in proper form for transfer, and such other instruments as the Board
          of Directors may require, shall be entitled to require the Corporation
          to redeem all or any part of the Shares outstanding in the name of
          such holder on the books of the Corporation, at a redemption price
          equal to the net asset value of such Shares determined as hereinafter
          set forth. Notwithstanding the foregoing, the Corporation may deduct
          from the proceeds otherwise due to any stockholder requiring the
          Corporation to redeem Shares a redemption charge not to exceed one
          percent (1%) of such net asset value or a reimbursement charge, a
          deferred sales charge or other charge that is integral to the
          Corporation's distribution program (which charges may vary within and
          among series and classes) as may be established from time to time by
          the Board of Directors."

          (e)  Striking out the words "Class" or "Class or Classes", as the case
     may be, from subsections (b) and (d) of Section 1 of Article VII and
     inserting the word "series" in lieu thereof.

          (f)  Striking out the last sentence of Section 1(g) of Article VII and
     inserting in lieu thereof:

          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

<PAGE>
 
          pursuant to said section (e) (other than an amendment reducing the
          compensation of the other party thereto) shall be effective unless
          assented to by the affirmative vote of a majority of the outstanding
          voting securities of the Corporation (as such phrase is defined in the
          Investment Company Act of 1940, as amended from time to time) entitled
          to vote on the matter."

          (g)  Striking out Section 3 of Article VII and inserting in lieu
     thereof:

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

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

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

                    The gross value of the assets of the Corporation belonging
                    to a series as of such determination time shall

                    value of all securities for which market quotations are
                    readily available and the fair value of other assets of the
                    Corporation belonging to that series (as such terms are
                    defined in subsection (a) of Section 2 of Article V) at such
                    determination time, all determined in accordance with sound
                    accounting practice.  Securities held shall be valued
                    pursuant to methods approved by the Board of Directors and
                    in accordance with applicable statutes and regulations.  The
                    determination of the market value of securities hereunder
                    may be determined by reference to any recognized source of
                    quotations or to a valuation service approved by the Board
                    of Directors.

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

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

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

                  Rule 12b-1 Distribution Plan and Agreement
 Lord Abbett Tax-Free Income Fund, Inc. -- California Series -- Class C Shares
 -----------------------------------------------------------------------------


          RULE 12b-1 DISTRIBUTION PLAN AND AGREEMENT dated as of July 12, 1996
by and between LORD ABBETT TAX-FREE INCOME FUND, INC., a Maryland corporation
(the "Fund"), on behalf of its CALIFORNIA SERIES (the "Series"), and LORD ABBETT
DISTRIBUTOR LLC, a New York limited liability company (the "Distributor").

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

          WHEREAS, the Fund desires to adopt a Distribution Plan and Agreement
(the "Plan") for the Series with the Distributor, as permitted by Rule 12b-1
under the Act, pursuant to which the Series 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 Series 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 Series 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 Series 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 series of the Fund or another Lord 
Abbett-sponsored fund (or for shares of a fund acquired by the Fund) will be
credited with the time held from the initial purchase of such other shares when
determining how long Shares mentioned in clause (ii) have been outstanding and
(B) payments will be based on Shares outstanding during any such quarter. Sales
in clause (i) above exclude Shares issued for reinvested dividends and
distributions, and Shares outstanding in clause (ii) above include Shares issued
for reinvested dividends and distributions which have been outstanding for one
year or more. The Board of Directors of the Fund shall from time to time
determine the amounts, within the foregoing maximum amounts, that the Series 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 Series 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 Series 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

                                       2
<PAGE>
 
primarily intended to result in the sale of Shares.  The Fund's Board of
Directors (in the manner contemplated in paragraph 10 of this Plan) shall
approve the timing, categories and calculation of any payments under this
paragraph 3 other than those referred to in the foregoing sentence.

          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 Series hereunder, the Distributor
shall not be deemed to have waived its rights under this Agreement to have the
Series 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 Series 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, the Series or any of the
shareholders, creditors, directors or officers of the Fund; provided however,
that nothing herein shall be deemed to protect the Distributor against any
liability to the Fund or the Series' shareholders by reason of willful
misfeasance, bad faith or gross negligence in the performance of its duties
hereunder, or by reason of the reckless disregard of its obligations and duties
hereunder.

          8.  This Plan shall become effective on the date hereof, and shall
continue in effect for a period of more than one year from such date only so
long as such continuance is specifically approved at least annually by a vote of
the Board of

                                       3
<PAGE>
 
Directors of the Fund, including the vote of a majority of the directors who are
not "interested persons" of the Fund and who have no direct or indirect
financial interest in the operation of this Plan or in any agreement related to
this Plan, cast in person at a meeting called for the purpose of voting on such
renewal.

          9.  This Plan may not be amended to increase materially the amount to
be spent by the Series 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
the event of its assignment.

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

                                                                  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 Tax-Free Income Fund, Inc.
                      Registration Statement on Form N-14
                     --------------------------------------

Ladies and Gentlemen:

          We have acted as counsel to Lord Abbett Tax-Free Income 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-
3942) (the "Registration Statement"), relating to the issuance of shares of the
capital stock of the California Series (the "Acquiring Fund"), a series of the
Registrant.

          Such shares are to be established and designated as the Class A shares
and the Class C shares (the "Class A shares" and the "Class C shares").  The
Class A shares are to be issued to Lord Abbett California Tax-Free Income Fund,
Inc., a Maryland corporation (the "Reorganized Fund"), 
<PAGE>
 
Lord Abbett Tax-Free Income Fund, Inc.
Page 2


pursuant to an Agreement and Plan of Reorganization (the "Reorganized Fund
Plan") between the Registrant, on behalf of the Acquiring Fund, and the
Reorganized Fund substantially in the form of Exhibit A-1 included in Part A of
the Registration Statement. The Class C shares are to be issued to Lord Abbett
California Tax-Free Income 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 "Acquired Trust Plan") between
the Registrant, on behalf of the Acquiring Fund, and the Securities Trust, on
behalf of the Acquired Trust, substantially in the form of Exhibit A-2 included
in Part A of the Registration Statement. Such issuances of the Class A and the
Class C shares are to be made in connection with the acquisitions by the
Acquiring Fund of the assets of, and the assumptions by the Acquiring Fund of
the liabilities of, the Reorganized Fund and the Acquired Trust, respectively.

          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:

          (a)  Class A shares.  Assuming that the Reorganized Fund and the
               --------------                                             
     Acquiring Fund duly execute and deliver the Reorganized Fund Plan, that the
     Reorganized Fund Plan and the reorganization provided for thereby are duly
     approved by the shareholders of the Reorganized Fund, that the transactions
     contemplated by the Reorganized Fund Plan are duly consummated and that the
     charter documents substantially in the forms of Exhibits 1(f), 1(g) and
     1(h) to the Registration Statement are duly approved and filed with the
     State Department of Assessments and Taxation of Maryland, the Class A
     shares issued pursuant to the Reorganized Fund Plan will be legally issued,
     fully paid and non-assessable.


 
                                                                     Exhibit 12

Ladies and Gentlemen:

          We have acted as counsel to Lord Abbett Tax-Free Income Fund, Inc., a
Maryland corporation ("Tax-Free Fund"), acting on behalf of its series, Lord
Abbett California Series ("Acquiring Fund"), and Lord Abbett Securities Trust,

a Delaware business trust ("Securities Trust"), acting on behalf of its series,
Lord Abbett California Tax-Free Trust ("Acquired Fund"), in connection with the
proposed acquisition (the "Reorganization") of all of the assets of Acquired
Fund by Acquiring Fund pursuant to the Agreement and Plan of Reorganization
dated as of _______ __, 1996, by and between Tax-Free Fund, on behalf of
Acquiring Fund, and Securities 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:

  Income Fund, Inc.
Lord Abbett Securities Trust           3                  [Date of the Closing]

          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 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.

Ladies and Gentlemen:

          We have acted as counsel to Lord Abbett Tax-Free Income Fund, Inc., a
Maryland corporation ("Tax-Free Fund"), acting on behalf of its series, Lord
Abbett California Series ("Acquiring Fund"), and Lord Abbett California Tax-Free

Fund"), in connection with the proposed acquisition (the "Reorganization") of
all of the assets of Acquired Fund by Acquiring Fund pursuant to the Agreement
and Plan of Reorganization dated as of _______ __, 1996, by and between Tax-Free
Fund, on behalf of Acquiring Fund, and 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 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

Dear Associate Chief Counsel (Domestic):

          By letter dated October 19, 1995 (the "Original Request"), the Lord
Abbett funds listed on Schedule A thereto requested that the Internal Revenue
Service issue rulings (1) that the dividends paid on each class of shares issued
                       -

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.
<PAGE>
 
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,

$1 million by dealers, on or after the series' effective date, including sales

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.

                               RULINGS REQUESTED
                               -----------------

          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.
<PAGE>
 
Internal Revenue Service               19                      October 19, 1995


                                  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
<PAGE>
 
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.

in this matter.  If for any reason the rulings requested cannot be issued on
the basis of the information contained herein, together with any additional
information, we hereby request a conference.

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

                                     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 payable 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 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.

          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.

          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
