                    A Lord Abbett Managed Investment Company
             90 Hudson Street o Jersey City, New Jersey 07302-3973

Dear Fellow Shareholder,

As you know, your Fund offered investors the unique opportunity to participate
in the stock market without the risk of losing their original investment.
Shareholders meeting certain conditions were protected through an insurance
policy issued by Financial Security Assurance, Inc. That insurance policy will
expire on May 31, 2000. After that date, all outstanding Fund shares will be
fully subject to the market risks inherent in equity funds.

As of January 31, 2000, your Fund held $55,003,120 in assets and has had an
average annual total return of 12.32% since inception.

In light of the expiration of the insurance policy, and increased shareholder
inquiries concerning the future of the Fund, Lord, Abbett & Co. (Lord Abbett)
recently proposed to the Fund's Board of Trustees that the Fund be combined with
the Lord Abbett Large-Cap Growth Fund (Large-Cap Growth Fund).

Following its review of this proposal, the Fund's Board of Trustees determined
unanimously that the combination of your Fund with the Large-Cap Growth Fund
would be in the best interests of the Fund and its shareholders. Accordingly,
the Board of Trustees has called a Special Meeting of Shareholders to consider
the proposed combination.

As you evaluate this proposed combination of your Fund and the Large-Cap Growth
Fund (the Funds), please note the following points:

o    Both Funds invest primarily in equity securities of large, established
     companies, although they have different investment objectives and
     strategies. The investment objective of the Equity Fund is long-term growth
     of capital and income without excessive fluctuations in market value. In
     contrast, the investment objective of the Large-Cap Growth Fund is
     long-term capital growth. Although the Large-Cap Growth Fund expects to
     retain a significant portion of the assets held by your Fund, its portfolio
     principally will consist of growth stocks. The Large-Cap Growth Fund does
     not anticipate investing any of its assets in U.S. Government securities
     except for temporary investment purposes. Currently, approximately 20% of
     your Fund's assets are invested in U.S. Government securities. These
     investments were made pursuant to restrictions imposed as a condition of
     its insurance policy. The Large-Cap Growth Fund has not purchased an
     insurance policy like the one owned by your Fund.

o    The proposed combination will be a tax-free reorganization for federal
     income tax purposes.

o    You will not be charged any transaction fees in the combination.

o    The total value of the Large-Cap Growth Fund shares you will receive will
     be the same as the total value of your Fund shares as of the close of
     business on the date that the combination is completed.

o    The proposed combination may create economies of scale in portfolio
     management, administration and operations resulting from larger asset size,
     thereby potentially reducing costs to you.

o    The expiration of the insurance policy will result in savings to the Fund
     and to you.

o    A vote in favor of the proposed combination is a vote to terminate the
     Equity Fund.

You may vote in any one of four ways:

     o    Via the Internet at http://www.proxyvote.com.

     o    By telephone, with a toll-free call to 1-800-690-6903.

     o    By mail, using the enclosed proxy card.

     o    In person at the meeting.

We encourage you to vote via the Internet or by telephone, using the 12-digit
"control" number that appears on your proxy card. These voting methods will save
your Fund a good deal of money that otherwise would be spent on postage.
Regardless of the method you choose, however, please take the time to read the
full text of the Combined Prospectus/Proxy Statement before voting.

YOUR VOTE ON THE PROPOSED COMBINATION IS CRITICAL. TO ENSURE THAT YOUR VOTE IS
COUNTED, IT IS IMPORTANT THAT YOU:

     1.   REVIEW THE ENCLOSED COMBINED PROSPECTUS/PROXY STATEMENT, AND

     2.   VOTE VIA THE INTERNET OR BY TELEPHONE, OR

          IN THE ENCLOSED ENVELOPE AS SOON AS POSSIBLE.

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

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

If the proposed combination is approved, shareholders should note that the
Equity Fund expects to pay its final distributions immediately prior to the
combination in additional shares (unless otherwise instructed). For operational
reasons, the Equity Fund does not intend to effect a reverse stock split, as it
has done in the past.


Sincerely,

                       COMBINED PROSPECTUS/PROXY STATEMENT
                              Dated March 31, 2000


                          Acquisition Of The Assets Of
                             LORD ABBETT EQUITY FUND
                  90 Hudson Street, Jersey City, NJ 07302-3973

                    By And In Exchange For Class A Shares Of
                        LORD ABBETT LARGE-CAP GROWTH FUND
                  90 Hudson Street, Jersey City, NJ 07302-3973

This Combined Prospectus/Proxy Statement relates to Class A shares (the "Class A
shares") of beneficial interest of the Lord Abbett Large-Cap Growth Fund (the
"Large-Cap Growth Fund") to be issued to, and in exchange for all the assets of,
Lord Abbett Equity Fund (the "Equity Fund", and together with the Large-Cap
Growth Fund, the "Funds"). In exchange for those assets, the Large-Cap Growth
Fund also will assume all of the liabilities of the Equity Fund. Following
receipt of the Large-Cap Growth Fund Class A shares, the Equity Fund will
terminate and distribute the Class A shares to the shareholders of the Equity
Fund. The shareholders of the Equity Fund are being asked to vote to approve or
disapprove these proposed transactions (the Reorganization), which are more
fully described in this Combined Prospectus/Proxy Statement.

Both Funds are registered, open-end, management investment companies. Lord,
Abbett & Co. (Lord Abbett) is the investment manager to both Funds.

The Boards of Trustees of the Funds have decided that the Reorganization is in
the best interests of the Equity Fund and the Large-Cap Growth Fund and their
respective shareholders. The Boards also have determined that the Reorganization
would not result in a dilution of the interests of the shareholders of either
Fund.

Any shareholder having a question regarding the meeting agenda or needing
assistance in voting should contact the Equity Fund at 1-800-426-1130.

This Combined Prospectus/Proxy Statement concisely sets forth the information
about the Large-Cap Growth Fund that a shareholder of the Equity Fund should
know before voting on the Reorganization. It should be read and retained for
future reference. Attached as an Appendix to this Combined Prospectus/ Proxy
Statement is a copy of the Agreement and Plan of Reorganization (the Plan) for
the Reorganization. This Combined Prospectus/Proxy Statement is accompanied by
the Prospectus of the Large-Cap Growth Fund dated December 30, 1999, which is
incorporated by reference into this Combined Prospectus/Proxy Statement. Also
incorporated herein by reference is the Statement of Additional Information
dated March 31, 2000 relating to this Combined Prospectus/Proxy Statement. The
Statement of Additional Information is available, upon request and at no charge,
from the Large-Cap Growth Fund by writing to 90 Hudson Street, Jersey City, NJ
07302-3973, or by calling 1-800-426-1130.

The Securities and Exchange Commission has not approved or disapproved these
securities nor passed upon the adequacy of this Combined Prospectus/Proxy
Statement. Any representation to the contrary is a criminal offense.

SPECIAL MEETING OF SHAREHOLDERS OF THE EQUITY FUND

     This Combined Prospectus/Proxy Statement is furnished in connection with
     the solicitation of proxies by and on behalf of the Board of Trustees of
     the Equity Fund to be used at a Special Meeting of Shareholders of the
     Equity Fund to be held at 10:00 a.m. on May 26, 2000, at the offices of
     Lord, Abbett & Co. (Lord Abbett) at 90 Hudson Street, Jersey City, New
     Jersey, 07302-3973, and at any adjournment thereof. This Combined
     Prospectus/Proxy Statement and the enclosed proxy card are first being
     mailed to shareholders of the Equity Fund on or about March 31, 2000.

     At the close of business on March 23, 2000 (the Record Date), there were
     issued and outstanding 1,920,729.50 shares of the Equity Fund. Only
     shareholders of record as of the close of business on the Record Date will
     be entitled to notice of, and to vote at, the meeting or any adjournment
     thereof. Shareholders of the Equity Fund are entitled to one vote for each
     full share, and a proportionate share of a vote for each fractional share.

     The presence in person or by proxy of the holders of a majority of the
     outstanding shares entitled to vote is required to constitute a quorum of
     the meeting. Approval of the Plan and the Reorganization requires the
     affirmative vote of a majority of the outstanding voting securities (as
     defined in the Investment Company Act of 1940 (Investment Company Act)) of
     the shares of the Equity Fund. This means that the Plan and the
     Reorganization must be approved by the lesser of: (i) 67% or more of the
     shares of the Equity Fund, if holders of more than 50% of the outstanding
     shares are present or represented by proxy; or (ii) more than 50% of the
     outstanding shares of the Equity Fund. Shares for which there is an
     abstention or broker non-vote shall be counted for quorum purposes but
     shall be considered to be a vote against the proposal. If the enclosed form
     of proxy is properly executed and returned in time to be voted at the
     meeting, or the shareholder votes via the Internet or by telephone prior to
     the meeting, the named proxies will vote the shares represented by the
     proxy in accordance with the shareholder's instructions.
     A proxy may be revoked by the shareholder at any time at or before the
     meeting by written notice to the Equity Fund, by execution of a later-dated
     proxy or by voting in person at the meeting. Unless revoked, all valid
     proxies will be voted in accordance with the specifications thereon or, in
     the absence of such specifications, for approval of the Plan and the
     Reorganization, and on any other matters as deemed appropriate. A vote in
     favor of the Reorganization is a vote to terminate the Equity Fund.

     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 Equity Fund may also request brokerage
     houses, custodians, nominees, and fiduciaries who are shareholders of
     record to forward proxy material to the beneficial owners. Half of the
     costs of the Reorganization will be borne by Lord Abbett and half by the
     Funds. These costs (including proxy solicitation costs of approximately
     $50,000) are estimated to total approximately $110,000.

     If sufficient votes to approve the Plan are not received by the meeting
     date, the persons named as proxies may propose one or more adjournment(s)
     of the meeting to allow further solicitation of proxies. In determining
     whether to adjourn the meeting, the following factors may be considered:
     the percentage of votes actually cast, the percentage of negative votes
     actually cast and the nature of any further solicitation and any
     information to be provided to shareholders with respect to such
     solicitation. Any such adjournment will require an affirmative vote of a
     majority of the shares present in person or by proxy and entitled to vote
     at the meeting. The persons named as proxies will vote on an adjournment
     after considering the best interests of all shareholders.

     If the Plan is not approved by the shareholders of the Equity Fund, or if
     the Reorganization is not completed for any other reason, the Equity Fund
     will continue to engage in business.

     Shareholders who redeem their Equity Fund shares before May 31, 2000 will
     lose the benefit of the guarantee provided by Financial Security Assurance,
     Inc. ("Financial Security"), as described below and in the Equity Fund's
     Prospectus dated October 1, 1999.

                                                             Equity Fund Proxy 1

FEES AND EXPENSES

     This table provides a summary comparison of the expenses of the Class A
     shares of the Large-Cap Growth Fund and the shares of the Equity Fund. The

(1)  No sales charge will be imposed in connection with the Reorganization.

(2)  A contingent deferred sales charge of 1.00% may be assessed on certain
     redemptions of Class A shares made within 24 months following any purchases
     made without a sales charge. No such charge will be imposed on shares
     acquired in the Reorganization because all the Equity Fund shareholders
     receiving such shares will satisfy the 24 month requirement when the
     holding period of their Equity Fund shares is taken into account.

(3)  Management fees are payable to Lord Abbett for the Funds' investment
     management.

(4)  Because 12b-1 fees are paid out on an ongoing basis, over time they will
     increase the cost of your investment and may cost you more than paying
     other types of sales charges. 12b-1 fees refer to fees incurred for
     activities that are primarily intended to result in the sale of Fund shares
     and service fees for shareholder account service and maintenance.

(5)  Other expenses include fees paid for miscellaneous items such as
     shareholder service fees and professional fees. (6) The total annual
     operating expenses of the Large-Cap Growth Fund are based on estimated
     expenses for the current fiscal year ending July 31, 2000. The annual
     operating expenses of the Equity Fund have been restated from the May 31,
     1999 fiscal year amounts to reflect the termination on May 31, 2000, of the
     guarantee provided by Financial Security Assurance, Inc., and the
     associated premium of .50% annually of the total amount guaranteed. For the
     fiscal year ended May 31, 1999, the Equity Fund's total expense ratio was
     1.35% which included expenses of .19% related to the guarantee.



================================================================================
Example
================================================================================
The Example below is intended to help you compare the cost of investing in the
Large-Cap Growth Fund with the cost of investing in the Equity Fund. The
Example, like that in other funds' prospectuses, assumes that you invest $10,000
in the Funds for the time periods indicated and redeem all of your shares at the
end of those periods. The Example also assumes that your investment has a 5%
return each year, that the Funds' operating expenses remain the same, and that
you paid the maximum sales load. No sales charge will be imposed in connection
with the Reorganization. Although your actual costs may be higher or lower,
based on these assumptions your costs would be:(1)

SUMMARY OF PROPOSAL

     The following is a summary of certain information contained elsewhere or
     incorporated by reference in this Combined Prospectus/Proxy Statement. You
     should read the entire Combined Prospectus/Proxy Statement.


OVERVIEW OF PROPOSED REORGANIZATION

     The Plan provides for the transfer to the Large-Cap Growth Fund of all of
     the assets of the Equity Fund in exchange for Class A shares and the
     assumption by the Large-Cap Growth Fund of all of the liabilities of the
     Equity Fund. The Class A shares then will be distributed to the Equity Fund
     shareholders and the Equity Fund will be terminated. As a result of the
     Reorganization, each shareholder of the Equity Fund will become the owner
     of that number of full and fractional Class A shares having an aggregate
     net asset value equal to the aggregate net asset value of their shares of
     the Equity Fund, as of the close of business on the date the Equity Fund
     assets are transferred to the Large-Cap Growth Fund. Completion of the
     Reorganization is subject to the approval of the Equity Fund's shareholders
     and other conditions.

     The Boards of Trustees of the Funds unanimously have decided that the
     Reorganization is in the best interests of the Equity Fund and the
     Large-Cap Growth Fund and their respective shareholders. The Boards also
     have determined that the Reorganization would not result in a dilution of
     the interests of the shareholders of either Fund. Among other factors, the
     Boards considered, based upon the recommendation of Lord Abbett, the
     investment manager to both Funds, the relative historical performance of
     the two Funds, the expiration of the guarantee provided by Financial
     Security on May 31, 2000, the poor prospects for future sales of shares of
     the Equity Fund, the prospect that the asset levels of the Equity Fund may
     decline following the expiration of the guarantee, and the historical and
     projected expense ratios of the Funds, including the fact that such expense
     ratios of the Large-Cap Growth Fund Class A shares were higher than those
     of the Equity Fund shares. In addition, the Boards considered the
     investment management experience of Stephen Humphrey, the portfolio manager
     of the Large-Cap Growth Fund, the prospects for future sales of shares of
     the Large-Cap Growth Fund, in light of its investment objective and
     portfolio management, and the likelihood that sales would be sufficient to
     allow it to reach an acceptably high asset level to realize administrative,
     portfolio management, distribution, shareholder service and other operating
     efficiencies. However, there is no guarantee that such operating
     efficiencies will occur.

     The Boards also considered the tax-free nature of the Reorganization, the
     similarities and differences among the investment objectives and policies
     of the two Funds, their related risk factors, and the fact that the Funds
     share the same service providers, including the investment manager,
     custodian and transfer agent. The Board of the Equity Fund considered other
     alternatives, including liquidation of the Equity Fund.

     In light of these factors and their fiduciary duties under federal and
     state law, the Boards unanimously have decided that the Reorganization is
     in the best interests of the Equity Fund and the Large-Cap Growth Fund and
     their respective shareholders. The Boards have also determined that the
     Reorganization would not result in a dilution of the interests of the
     shareholders of either Fund.


LARGE-CAP GROWTH FUND CLASS A SHARES
     The Large-Cap Growth Fund has five classes of shares: Classes A, B, C, P
     and Y, each of which invests in the same portfolio, but bears different
     expenses and receives different levels of dividends. If the Reorganization
     is completed, Equity Fund shareholders will receive Class A shares.

                                                             Equity Fund Proxy 3
<PAGE>


INVESTMENT OBJECTIVES AND POLICIES OF THE
EQUITY FUND AND THE LARGE-CAP GROWTH FUND

     Although both Funds invest primarily in equity securities of large,
     established companies, they have different investment objectives and
     strategies.

     The investment objective of the Equity Fund is long-term growth of capital
     and income without excessive fluctuations in market value. In contrast, the
     investment objective of the Large-Cap Growth Fund is long-term capital
     growth.

     Investments in the Equity Fund are insured by Financial Security, which
     guarantees that the net asset value of each initially purchased share will
     not be less than $10 on May 31, 2000 if certain conditions are met. The
     Large-Cap Growth Fund has not purchased an insurance policy similar to the
     one owned by the Equity Fund and does not intend to do so in the future.

     Under normal circumstances, at least 65% of the Equity Fund's net assets is
     invested in equity securities, although, under Financial Security's
     investment guidelines, due to market conditions, the Equity Fund may be
     required to invest more than 35% of its net assets in U.S. Government
     securities. In addition, under Financial Security's insurance investment
     guidelines, the Equity Fund may be required to invest a portion of its
     assets in short-term debt securities, which could reduce the benefit from
     any upswing in the equity market and prevent the Equity Fund from achieving
     its investment objective. Under normal circumstances, the Large-Cap Growth
     Fund invests at least 65% of its total assets in equity securities of
     large, established companies with market capitalizations of at least $8
     billion. The Large-Cap Growth Fund is not subject to the stringent
     insurance investment guidelines imposed on the Equity Fund.

     The Equity Fund believes that the needs of its investors will best be
     served by an investment that exhibits growth, characterized by as few
     fluctuations in market value as is possible. For this reason, the Equity
     Fund tries to keep its assets invested in securities that are selling at
     reasonable prices in relation to value and, thus, will forego some
     opportunities for gains when, in its judgment, they are too risky. In
     contrast, the Large-Cap Growth Fund uses a bottom up investment research
     approach that seeks to identify individual companies with expected earnings
     growth potential and consistency that may not be recognized by the market
     at large.

     In addition, there are differences between the investment policies of, and
     investment techniques used by, the Funds. In particular, the Large-Cap
     Growth Fund may invest to a greater degree than the Equity Fund in illiquid
     securities, futures contracts, options on futures contracts, and options,
     all of which may present investment risks. Further, although both Funds are
     diversified, the Large-Cap Growth Fund's investment policy does not require
     as great a degree of diversification. This means that the Large-Cap Growth
     Fund may invest to a greater extent in the securities of a single issuer,
     which may increase its volatility.


PURCHASES AND EXCHANGES

     Large-Cap Growth Fund Class A shares are available through certain
     authorized dealers at the public offering price, which is the net asset
     value plus a front-end sales load. Shareholders of the Equity Fund may
     exchange their shares now for shares of the Lord Abbett Large-Cap Growth
     Fund. However, shareholders who exchange their shares before May 31, 2000
     will lose the benefit of the guarantee provided by Financial Security. In
     addition, each such exchange will represent a sale of shares for which a
     shareholder may have to recognize a taxable gain or loss. In contrast, no
     gain or loss will be recognized by shareholders of the Equity Fund upon the
     exchange of their Equity Fund shares for new Class A shares in the
     Reorganization.

     The Equity Fund currently is not offering its shares for purchase. If the
     Reorganization is not approved, the Board of Trustees of the Equity Fund
     will consider whether to offer its shares for purchase.

4 Equity Fund Proxy

<PAGE>

     Net asset value per share for each class of Fund shares is calculated each
     business day at the close of regular trading on the New York Stock Exchange
     ("NYSE"), normally 4:00 p.m. Eastern time. Purchases and sales of Fund
     shares are executed at the NAV next determined after the Fund receives your
     order in proper form. In calculating NAV, securities for which market
     quotations are available are valued at those quotations. Securities for
     which such quotations are not available are valued at fair value under
     procedures approved by the Boards of the Funds.


DIVIDEND POLICIES AND OPTIONS

     The Equity Fund normally distributes net investment income and any net
     capital gains annually in December. It also may pay supplemental dividends
     and capital gains distributions during the year. Historically, the Fund has
     paid all dividends and distributions in the form of additional shares and
     used reverse stock splits to maintain the original number of shares
     purchased, assuming no shares are redeemed. It is currently contemplated,
     however, that the Equity Fund will pay its final distributions, as
     described under "Tax Considerations" below, to shareholders in additional
     shares (unless shareholders request payment in cash) and will not employ a
     reverse stock split. The effect of this change will be to reduce the amount
     of the Financial Security guarantee by the amount of these distributions.

     The Large-Cap Growth Fund has a generally similar dividend and distribution
     policy although it does not employ reverse stock splits. It normally pays
     its shareholders dividends from its net investment income and distributes
     its net capital gains (if any) annually. Your distributions will be
     reinvested in the Fund unless you instruct the Fund to pay them to you in
     cash. There are no sales charges on reinvestments.


REDEMPTION PROCEDURES

     The redemption procedures of the Equity Fund and the Large-Cap Growth Fund
     are substantially the same. You may redeem your shares by broker, by
     telephone, or by mail, as explained below.

     By Broker. Call your investment professional for instructions on how to
     redeem your shares.

     By Telephone. To obtain the proceeds of a redemption of $50,000 or less
     from your account, you or your representative should call the Funds at
     1-800-821-5129.

     By Mail. Submit a written redemption request indicating the name(s) in
     which the account is registered, the Fund's name, the class of shares, your
     account number, and the dollar value or number of shares you wish to sell.


TAX CONSIDERATIONS
     The completion of the Reorganization is subject to receipt of an opinion of
     counsel, substantially to the effect that, among other things, the
     Reorganization will not cause gain or loss to be recognized by the Equity
     Fund or its shareholders for federal income tax purposes.

     Shareholders should note that prior to the Reorganization, the Equity Fund
     may, to the extent permitted by law and consistent with the opinion to be
     issued by Wilmer, Cutler & Pickering, legal counsel to the Large-Cap Growth
     Fund and the Equity Fund, dispose of some of the securities in its
     portfolio and reinvest the proceeds in other securities consistent with its
     investment objectives. In addition, immediately before the Reorganization,
     the Equity Fund will declare and distribute a dividend that will have the
     effect of distributing to the Equity Fund shareholders all of the Equity
     Fund's previously undistributed investment company taxable income and net
     realized capital gains. To the extent that the Equity Fund disposes of
     securities in its portfolio before the Reorganization, the Equity Fund may
     realize a greater amount of net capital gains that would then be
     distributed to Equity Fund shareholders. These distributions will be
     taxable to the Equity Fund shareholders. The ability of either Fund to
     dispose of assets in connection with the Reorganization is limited by
     federal tax requirements. For additional information, see "Information
     about the Reorganization -- Federal Income Tax Considerations."

                                                             Equity Fund Proxy 5
<PAGE>


RISK FACTORS

     Each Fund is subject to the general risks and considerations associated
     with equity investing. The value of an investment in the Funds will
     fluctuate in response to movements in the stock market generally and to the
     changing prospects of individual companies in which the Funds invest.

     In addition, the Funds are subject to the particular risks associated with
     the types of stocks in which they invest: value-oriented stocks in the case
     of the Equity Fund; and growth stocks in the case of the Large-Cap Growth
     Fund. As different types of stocks shift in and out of favor depending on
     market and economic conditions, one type may perform differently than the
     market as a whole and other types of stock. For instance, the market may
     fail to recognize the intrinsic value of particular value-oriented stocks
     for a long time. Also, growth companies may grow faster than other
     companies which may result in more volatility in their stock prices.

     If a Fund's assessment of a company's value or prospects for exceeding
     earnings expectations or market conditions is wrong, the Fund could suffer
     losses or produce poor performance relative to other funds, even in a
     rising market.

     Investments in the Equity Fund are insured by Financial Security. Financial
     Security guarantees that the net asset value of each initially purchased
     share will not be less than $10 on May 31, 2000, subject to certain
     conditions. Under Financial Security's insurance investment guidelines, the
     Fund may be required to invest some of its assets in short-term debt
     securities, which would reduce the risk of excessive fluctuations in market
     value. Due to these investment guidelines, an investment in the Equity Fund
     historically may have been significantly less volatile than an investment
     in other equity funds, including the Large-Cap Growth Fund. The Large-Cap
     Growth Fund does not intend to purchase an insurance policy like the policy
     owned by the Equity Fund.



INFORMATION ABOUT THE REORGANIZATION


THE PLAN

     On May 31, 2000 (the Closing Date), assuming the conditions discussed below
     are met, the Equity Fund will transfer all its assets to the Large-Cap
     Growth Fund in exchange for new Class A shares of the Large-Cap Growth Fund
     having an aggregate net asset value equal to the aggregate value of the
     assets, less liabilities, of the Equity Fund and the assumption by the
     Large-Cap Growth Fund of all the liabilities of the Equity Fund. The Equity
     Fund will distribute as of the Closing Date such new 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 Equity Fund. The
     net asset value of the new Class A shares and the value of the Equity
     Fund's assets and the amount of its liabilities will be determined as of
     the Closing Date in accordance with the Large-Cap Growth Fund's valuation
     procedures, which are the same as those used by the Equity Fund.

     Although the Equity Fund may dispose of some of the securities in its
     portfolio prior to the Reorganization and reinvest the proceeds in other
     securities consistent with its investment objective, the Equity Fund will
     not dispose of assets which, in the aggregate, will result in less than 50%
     of the historic business assets of the Equity Fund being transferred to the
     Large-Cap Growth Fund in the Reorganization. The Equity Fund will pay final
     dividends prior to the Reorganization that will have the effect of
     distributing all of its undistributed investment company taxable income and
     net realized capital gains to its shareholders before the Reorganization.

     The obligations of the Large-Cap Growth Fund and the Equity Fund to
     complete the Reorganization are subject to the satisfaction of certain
     conditions, including: (a) approval and authorization of the Reorganization
     by the vote of a majority of the shares of the Equity Fund voted on the
     matter if a quorum is present and (b) 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."

<PAGE>


     This summary of the Plan is not complete, and is subject in all respects to
     provisions of, and is qualified in its entirety by reference to the Plan, a
     copy of which is attached as an Appendix hereto.

REASONS FOR THE REORGANIZATION

     The Boards of Trustees of the Funds, including in each case a majority who
     are not interested persons (as defined in the Investment Company Act) of
     either Fund or of Lord Abbett, approved the Plan and the Reorganization on
     March 9, 2000, and determined that participation in the proposed
     Reorganization is in the best interests of the shareholders of each of the
     Funds and that the interests of existing shareholders of the Funds will not
     be diluted as a result of the Reorganization.


FEDERAL INCOME TAX CONSIDERATIONS

     The completion of the Reorganization is conditioned on the receipt of an
     opinion of Wilmer, Cutler & Pickering, legal counsel to the Large-Cap
     Growth Fund and the Equity Fund, substantially to the effect that, for
     federal income tax purposes:

     (a)  The acquisition by the Large-Cap Growth Fund of substantially all the
          assets of the Equity Fund in exchange for voting Class A shares of the
          Large-Cap Growth Fund and the Large-Cap Growth Fund's assumption of
          the Equity Fund's liabilities, followed by the distribution by the
          Equity Fund to its shareholders of the Large-Cap Growth Fund shares,
          in complete liquidation, will constitute a reorganization within the
          meaning of section 368(a) of the Internal Revenue Code of 1986, as
          amended (the "Code"). The Large-Cap Growth Fund and the Equity Fund
          will each be a "party to a reorganization" within the meaning of
          section 368(b) of the Code.

     (b)  No gain or loss will be recognized by the Equity Fund upon the
          transfer of substantially all of its assets to the Large-Cap Growth
          Fund solely in exchange for Class A shares of the Large-Cap Growth
          Fund and the Large-Cap Growth Fund's assumption of the Equity Fund's
          liabilities or upon the distribution of such Large-Cap Growth Fund
          shares to the Equity Fund shareholders.

     (c)  The Large-Cap Growth Fund will recognize no gain or loss upon the
          receipt of substantially all of the assets of the Equity Fund in
          exchange solely for voting Class A shares of the Large-Cap Growth Fund
          and the assumption of the Equity Fund's liabilities.

     (d)  The shareholders of the Equity Fund will recognize no gain or loss on
          the receipt of Class A shares of the Large-Cap Growth Fund (including
          any fractional share interests to which they may be entitled) solely
          in exchange for their Equity Fund shares.

     (e)  The basis of the assets of the Equity Fund in the hands of the
          Large-Cap Growth Fund will be the same as the basis of such assets in
          the hands of the Equity Fund immediately prior to the transfer.

     (f)  The holding period of the assets of the Equity Fund in the hands of
          the Large-Cap Growth Fund will include the period during which those
          assets were held by the Equity Fund.

     (g)  The basis of the Large-Cap Growth Fund shares received by each Equity
          Fund shareholder will be the same as the basis of the Equity Fund
          shares surrendered in exchange therefor.

     (h)  The holding period of the Class A shares of the Large-Cap Growth Fund
          received by each Equity Fund shareholder in exchange for Equity Fund
          shares (including fractional shares to which such a shareholder may be
          entitled) will include the period that the shareholder held the Equity
          Fund shares exchanged therefor, provided that the shareholder held
          such shares as a capital asset on the date of the exchange.

                                                            Equity Fund Proxy  7

<PAGE>

     The Funds have not sought a tax ruling from the Internal Revenue Service as
     to the tax consequences of the Reorganization, but will rely on the opinion
     of counsel. Such an opinion is not binding on the Internal Revenue Service
     and does not preclude the Internal Revenue Service from adopting a contrary
     position.

     Shareholders should note that prior to the Reorganization, the Equity Fund
     may, to the extent permitted by law and consistent with the opinion to be
     issued by Wilmer, Cutler & Pickering discussed above, dispose of some of
     the securities in its portfolio and reinvest the proceeds in other
     securities consistent with its investment objectives. In addition,
     immediately before the Reorganization, the Equity Fund will declare and
     distribute a dividend that will have the effect of distributing to the
     Equity Fund shareholders all of the Equity Fund's previously undistributed
     investment company taxable income and net realized capital gains. To the
     extent that the Equity Fund disposes of securities in its portfolio before
     the Reorganization, the Equity Fund may realize a greater amount of net
     capital gains that would then be distributed to Equity Fund shareholders.
     These distributions will be taxable to the Equity Fund shareholders. The
     ability of either Fund to dispose of assets in connection with the
     Reorganization is limited by federal tax requirements.

     This discussion relates only to the general federal income tax consequences
     of the Reorganization. Shareholders should consult their own tax advisers
     concerning the tax consequences of the Reorganization to them, including
     any state or local tax consequences of the Reorganization and any special
     considerations that may apply in their individual circumstances.


EXPENSES OF THE REORGANIZATION

     Expenses of the Reorganization, including legal and accounting expenses,
     the costs of proxy solicitation, and the preparation of this Combined
     Prospectus/Proxy Statement, will be borne 50% by Lord Abbett and 50% by the
     Funds. If the Reorganization is completed, the expenses of the Equity Fund,
     to the extent not paid before the Closing Date, will be assumed by the
     Large-Cap Growth Fund and taken into account in determining the net assets
     of the Equity Fund for the purpose of calculating the number of new Class A
     shares to be issued to the Equity Fund.


CAPITALIZATION

     The following table sets forth the capitalization of the Large-Cap Growth
     Fund and the Equity Fund as of January 31, 2000, and the pro forma
     capitalization of the Large-Cap Growth Fund as if the Reorganization had
     occurred on that date. The net assets include an accrual for estimated
     Reorganization expenses in the amount of $55,000, and a distribution of
     undistributed income of $48,122, and undistributed, realized capital gains
     of $2,096,446. The table reflects a pro forma exchange ratio of
     approximately 2.6 Class A shares for each Equity Fund share. If the
     Reorganization is completed, the actual exchange ratio may vary from this
     ratio due to changes in the market value of the portfolio securities of
     both the Large-Cap Growth Fund and the Equity Fund between January 31,
     2000, and the Closing Date, and changes in the amounts of undistributed net
     investment income and undistributed net realized gain/loss of the Large-Cap
     Growth Fund and the Equity Fund during that period.

COMPARATIVE INFORMATION ABOUT the
LARGE-CAP GROWTH FUND AND THE EQUITY FUND


MANAGEMENT

     Lord Abbett is the investment adviser to both Funds. Founded in 1929, Lord
     Abbett manages one of the nation's oldest mutual fund complexes, with
     approximately $35 billion in more than 40 mutual fund portfolios and other
     advisory accounts.

     Under its Management Agreement, the Equity Fund pays Lord Abbett a monthly
     fee based on average daily net assets for each month at the annual rate of
     .65 of 1%. For the fiscal year ended May 31, 1999, the actual management
     fee paid by the Equity Fund to Lord Abbett amounted to .65 of 1% of the
     Equity Fund's average daily net assets. The Equity Fund pays all expenses
     not expressly assumed by Lord Abbett, including, without limitation, 12b-1
     Plan expenses, trustees' fees and expenses, association membership dues,
     legal and auditing fees, taxes, transfer and dividend disbursing agent
     fees, shareholder servicing costs, custody fees, fees for reviewing
     compliance with Financial Security's insurance investment guidelines,
     expenses relating to shareholder meetings, expenses of preparing, printing
     and mailing shareholder reports, expenses of registering the Equity Fund's
     shares under federal and state securities laws, insurance premiums,
     including the annual fee paid to Financial Security for its guarantee, and
     brokerage and other expenses relating to the execution of portfolio
     transactions.

<PAGE>


     Lord Abbett uses a team of portfolio managers and analysts acting together
     to manage the Equity Fund's investments. Robert G. Morris heads the team,
     the other senior member of which is John J. Walsh. Both Mr. Morris and Mr.
     Walsh are Partners of Lord Abbett and have been with the company for more
     than five years.

     Under its Management Agreement, the Large-Cap Growth Fund pays Lord Abbett
     a monthly fee of .75 of 1% based on average daily net assets for each
     month. In addition, the Large-Cap Growth Fund pays all expenses not
     expressly assumed by Lord Abbett.

     Stephen Humphrey serves as Executive Vice President and Portfolio Manager
     of the Lord Abbett Large-Cap Growth Fund and is primarily responsible for
     the day-to-day management of the Large-Cap Growth Fund. Mr. Humphrey joined
     Lord Abbett in 1999; before that he was a Vice President and Portfolio
     Manager at Chase Manhattan Bank (and its predecessors) from 1976 - 1999,
     managing private accounts from 1981 and pooled investment funds from 1985.


HISTORICAL PERFORMANCE OF PORTFOLIO MANAGER

     From March 17, 1997 until August 17, 1999, Mr. Humphrey was primarily
     responsible for the day-to-day management of the Chase Vista Select Large
     Cap Growth Fund, a separate series of the Mutual Fund Select Group, a
     registered investment company. As the portfolio manager of this fund, Mr.
     Humphrey had full discretionary authority over the selection of investments
     for the fund. From the fund's inception on January 1, 1997 until March 17,
     1997, a team of investment professionals at Chase Manhattan Bank, including
     Mr. Humphrey, was responsible for the management of the fund's portfolio.

     The cumulative total return for the Chase Vista Select Large Cap Growth
     Fund from March 17, 1997 through July 31, 1999 was 109.01%. At July 31,
     1999, this fund had $825.2 million in net assets. As shown in the table
     below, average annual total returns for the one year period ended July 31,
     1999 and for the period during which Mr. Humphrey managed that fund,
     compared with the performance of the Standard & Poor's 500(R) Composite
     Stock Price Index (the "S&P 500(R) Index") and the Lipper Large Cap Growth
     Fund average, were:

     Cap Growth Fund average during the period from March 20, 1997 through July

     Fund.


     Historical performance is not indicative of future performance. Although
     the Lord Abbett Large-Cap Growth Fund and the Chase Vista Select Large Cap
     Growth Fund have substantially similar investment objectives, policies and
     strategies, the Chase Vista Select Large Cap Growth Fund is a separate fund
     and its historical performance is not indicative of the future performance
     of the Lord Abbett Large-Cap Growth Fund. For the periods shown above, the
     anticipated expenses of the Lord Abbett Large-Cap Growth Fund may have been
     higher than

     the expenses of the Chase Vista Select Large Cap Growth Fund. Higher
     expenses, of course, would reduce a fund's performance. The Chase Vista
     Select Large Cap Growth Fund was the only investment vehicle that Mr.
     Humphrey managed during the period he was employed at Chase Manhattan Bank
     that has or had substantially similar investment objectives, policies and
     strategies as those of the Lord Abbett Large-Cap Growth Fund. Share prices
     and investment returns will fluctuate reflecting market conditions, as well
     as changes in company-specific fundamentals of portfolio securities.

MANAGEMENT'S DISCUSSION OF EQUITY FUND'S
1999 FISCAL YEAR PERFORMANCE

     Lord Abbett Equity Fund completed its most recent fiscal year on May 31,
     1999. The Equity Fund's net asset value was $29.36 per share versus $26.66
     per share on May 31, 1998. The Equity Fund's total return -- its percent
     change in net asset value with all distributions reinvested -- for the
     period was 10.17%.

     U.S. stocks were subject to significant volatility during the first half of
     your Fund's fiscal year. However, a more favorable environment developed
     later in the period as investors' concerns regarding diminished corporate
     earnings eased somewhat and low inflation and strong economic growth
     continued in the U.S. In the early months of 1999, investor sentiment
     continued to improve as Asian countries, which had been hit hard by
     currency problems and fallout from the faltering Japanese economy, began to
     recover. Japan's efforts to address its economic and banking system
     problems have given support to other Pacific Rim economies and have
     generated hope that the financial crises in that region may be nearing an
     end.

     The downturn in the market that occurred in the third quarter of 1998
     created an opportunity for the Fund to establish and add to positions in
     stocks that, in our opinion, became undervalued due to investor sentiment
     rather than deteriorating company fundamentals. During the period,
     positions the Equity Fund established or strengthened in
     telecommunications, technology, and select financial services companies,
     performed well. An increase in long-term interest rates, brought on by a
     rise in commodity prices, resulted in markdowns on the Fund's electric
     utility holdings.

     Lord Abbett anticipates that the domestic economy will continue to grow in
     1999, fueled in part by strong consumer spending. If recovery in Asia also
     continues, a global economic expansion seems likely for 2000. In any event,
     Lord Abbett expects to remain watchful of global inflationary pressures
     (brought on by rising commodity prices and a tightening U.S. labor market),
     interest rates, and valuations and volatility in the U.S. equity market.
     Presently, Lord Abbett does not expect inflation to exceed our earlier
     forecast of approximately 2-21 1/42% in 1999. Lord Abbett will continue to
     seek out large-company stocks at attractive prices, and expect that some of
     these values may be found in energy companies and in the cyclical
     commodities sector, which includes aluminum and paper companies and
     selected manufacturing companies.

     Lord Abbett of service fees at an annual rate not to exceed .25% of the net
     asset value of such shares, including any shares issued for reinvested
     dividends and distributions. The Large-Cap Growth Fund has a Rule 12b-1
     plan for Class A that provides for distribution and service fees of up to
     .35% annually (plus distribution fees of up to 1% on certain qualifying
     purchases).

     As shown above under Fee Table on page 2, the pro forma expense ratio for
     the Class A shares of the Large-Cap Growth Fund for the current fiscal year
     is estimated to be 1.45%, compared to an expense ratio for the fiscal year
     ended May 31, 1999 of 1.35% for the Equity Fund. This expense ratio for the
     Equity Fund includes expenses of .19% related to the guarantee provided by
     Financial Security. After May 31, 2000, the Equity Fund no longer will pay
     those expenses.


INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS

     Although both Funds invest primarily in equity securities of large,
     established companies, they have different investment objectives and
     strategies.

     The investment objective of the Equity Fund is long-term growth of capital
     and income without excessive fluctuations in market value. In contrast, the
     investment objective of the Large-Cap Growth Fund is long-term capital
     growth.

     Investments in the Equity Fund are insured by Financial Security, which
     guarantees that the net asset value of each initially purchased share will
     not be less than $10 on May 31, 2000 if certain conditions are met. The
     Large-Cap Growth Fund has not purchased an insurance policy similar to the
     one owned by the Equity Fund and does not intend to do so in the future.

     Under normal circumstances, at least 65% of the Equity Fund's net assets is
     invested in equity securities, although, under Financial Security's
     investment guidelines, due to market conditions, the Equity Fund may be
     required to invest more than 35% of its net assets in U.S. Government
     securities. In addition, under Financial Security's insurance investment
     guidelines, the Equity Fund may be required to invest a portion of its
     assets in short-term debt securities, which could reduce the benefit from
     any upswing in the equity market and prevent the Equity Fund from achieving
     its investment objective. Currently, approximately 20% of the Equity Fund's
     assets are invested in U.S. Government securities. Under normal
     circumstances, the Large-Cap Growth Fund invests at least 65% of its total
     assets in equity securities of large, established companies with market
     capitalizations of at least $8 billion. The Large-Cap Growth Fund is not
     subject to the stringent insurance investment guidelines imposed on the
     Equity Fund and does not anticipate investing any of its assets in U.S.
     Government securities except for temporary investment purposes.

     Typically, in choosing stocks, the Equity Fund looks for companies using a
     three-step process, which is different from the Large-Cap Growth Fund's
     investment approach:

     o    Quantitative research is performed on a universe of large, seasoned,
          U.S. and multinational companies to identify which stocks the Equity
          Fund believes represent the best bargains;

     o    Fundamental research is conducted to assess a company's operating
          environment, resources and strategic plans and to determine its
          prospects for exceeding the earnings expectations reflected in its
          stock price;

     o    Business cycle analysis is used to assess the economic and
          interest-rate sensitivity of the Equity Fund's portfolio, helping the
          Fund assess how adding or deleting stocks changes its portfolio's
          overall sensitivity to economic activity and interest rates.


14 Equity Fund Proxy

<PAGE>

     The Equity Fund is intended for long-term investors who purchased shares
     and might redeem shares to meet their own financial requirements rather
     than to take advantage of price fluctuations. The Equity Fund believes the
     needs of such investors will best be served by an investment that exhibits
     growth, characterized by as few fluctuations in market value as possible.
     For this reason, the Equity Fund tries to keep its assets invested in
     securities that are selling at reasonable prices in relation to value and,
     thus, will forgo some opportunities for gains when, in its judgment, they
     are too risky.

     To identify attractive companies for investment, the Large-Cap Growth Fund
     uses a bottom up investment research approach that seeks to identify
     individual companies with expected earnings growth potential and
     consistency that may not be recognized by the market at large. This
     approach, different from that of the Equity Fund, is based on the following
     steps:

     o    Identifying large-capitalization companies with at least a 10%
          consistent, sustainable growth rate;

     o    Focusing on those companies demonstrating a positive historical
          performance as well as favorable earnings prospects for the future;

     o    Focusing on companies also demonstrating successful strategic business
          plan selection, strategy and execution, reflecting strong management
          leadership; and

     o    Focusing on companies demonstrating leadership positions within their
          industries.

OTHER INVESTMENT TECHNIQUES

     The Funds use similar investment techniques, although there are some
     differences in the techniques used by each Fund. The techniques, and the
     differences, are summarized below.

     Adjusting Investment Exposure. Both Funds may, but are not required to, use
     various strategies to change their investment exposure to adjust to
     changing security prices, interest rates, currency exchange rates,
     commodity prices and other factors. The Funds may use these transactions to
     change the risk and return characteristics of their portfolios. If they
     judge market conditions incorrectly or use a strategy that does not
     correlate well with their investments, it could result in a loss, even if
     the Fund intended to lessen risk or enhance returns. These transactions may
     involve a small investment of cash compared to the magnitude of the risk
     assumed and could produce disproportionate gains or losses. Also, these
     strategies could result in losses if the counterparty to a transaction does
     not perform as promised.

     Diversification. Although each Fund is diversified, the Equity Fund's
     investment policy requires a greater degree of diversification. The Equity
     Fund will not purchase a security if, as a result, more than 5% of the
     Fund's total assets would be invested in securities of a single issuer, or
     the Fund would own more than 10% of the outstanding voting securities of
     the issuer. U.S. Government securities are not subject to these
     requirements. The Large-Cap Growth Fund has similar diversification
     requirements, but they apply only to 75% of its assets. This means that the
     Large-Cap Growth Fund may invest 25% of its assets in securities of a
     single issuer, which could result in greater volatility.

     Futures Contracts, Options on Futures Contracts, and Options Transactions.
     The Funds differ in their use of futures contracts, options on futures
     contracts, and options transactions.

     Both Funds may only sell (write) covered call options. This means that the
     Funds may only sell call options on securities that they own. A call option
     on securities gives the buyer, in return for a premium paid, the right for
     a specified period of time to buy the securities subject to the option at a
     specified price (the exercise price). The writer of a call option, in
     return for the premium, has the obligation, upon exercise of the option, to
     deliver, depending upon the terms of the option contract, the underlying
     securities to the buyer upon receipt of the

                                                            Equity Fund Proxy 15

<PAGE>

     exercise price. When a Fund writes a call option, it gives up the potential
     for gain on the underlying securities in excess of the exercise price of
     the option during the period that the option is open.

     Options on stock indices are similar to options on equity securities except
     that, rather than the right to take or make delivery of stock at a
     specified price, an option on a stock index gives the holder the right, in
     return for a premium paid, to receive, upon exercise of the option, an
     amount of cash if the closing level of the stock index upon which the
     option is based is greater than, in the case of a call, or less than, in
     the case of a put, the exercise price of the option. The writer of an index
     option, in return for a premium, is obligated to pay the amount of cash due
     upon exercise of the option.

     Each Fund may write put options on equity securities or stock indices that
     are traded on national securities exchanges. A put option gives the buyer
     of the option the right to sell, and the seller of the option the
     obligation to buy, the underlying instrument during the option period. The
     Large-Cap Growth Fund may write only covered put options to the extent that
     cover for such options does not exceed 15% of the Fund's net assets,
     whereas the limitation applicable to the Equity Fund is 10%. The Large-Cap
     Growth Fund will not purchase an option if, as a result of such purchase,
     more than 10% of its total assets would be invested in premiums for such
     options.

     The Large-Cap Growth Fund may buy and sell futures contracts, and options
     on futures contracts. A financial futures transaction is the purchase or
     sale of an exchange-traded contract to buy or sell a specified financial
     instrument or index at a specific future date and price. The Fund will not
     enter into any futures contracts, or options thereon, if the aggregate
     market value of the securities covered by futures contracts plus options on
     such financial futures exceeds 50% of its total assets.

     A Fund's transactions, if any, in futures, options on futures and other
     options involve additional risk of loss. Loss may result from a lack of
     correlation between changes in the value of these derivative instruments
     and the Fund's assets being hedged, the potential illiquidity of the
     markets for derivative instruments, or the risks arising from margin
     requirements and related leverage factors associated with such
     transactions. The use of these investment techniques also involves the risk
     of loss if Lord Abbett is incorrect in its expectation of fluctuations in
     securities prices. In addition, the loss that may be incurred by the
     Large-Cap Growth Fund in entering into futures contracts and in writing
     call options on futures is potentially unlimited and may exceed the amount
     of the premium received.

     Investments in Illiquid Securities. Both Funds may invest in illiquid
     securities, which include securities that are not traded on the open market
     or that trade irregularly or in very low volume. They may be difficult or
     impossible to sell at the time and price a Fund would like. The Equity Fund
     may invest up to 10% of its assets in illiquid securities. In addition,
     this policy is fundamental, which means that it may be changed only by a
     vote of shareholders. The Large-Cap Growth Fund may invest up to 15% of its
     assets in illiquid securities. The Large-Cap Growth Fund policy is not
     fundamental and may be changed by its Board of Trustees, without a
     shareholder vote.

     Portfolio Securities Lending. Both Funds may lend securities to
     broker-dealers and financial institutions, as a means of earning income.
     This practice could result in a loss or delay in recovering a Fund's
     securities if the borrower defaults. The Funds limit their loans to no more
     than 5% of their gross assets. All loans are fully collateralized.


SHAREHOLDER RIGHTS

     The rights of the Equity Fund shareholders will not change in an adverse
     way as a result of the Reorganization. After the Reorganization, the rights
     of the former shareholders of the Equity Fund (new Class A shareholders of
     the Large-Cap Growth Fund) will be governed by the Large-Cap Growth Fund's
     Declaration of Trust, By-Laws and applicable Delaware law, rather than by
     the Equity Fund's Declaration of Trust and By-Laws and applicable
     Massachusetts law. The operations of the Large-Cap Growth Fund will
     continue to be subject to the provisions of the Investment Company Act and
     the rules and regulations of the Commission thereunder.

16 Equity Fund Proxy

<PAGE>

     The current Boards of Trustees of the Funds are comprised of the same
     individuals. The responsibilities, powers and fiduciary duties of the
     trustees of the Funds are substantially the same. Each Fund's Declaration
     of Trust provides for indemnification of the trustees for actual or
     threatened liabilities arising out of the trustees' service in their
     capacity as trustees of the Fund, except with respect to any matter as to
     which a trustee has been adjudicated as to have not been acting in good
     faith in the reasonable belief that his or her action was in the best
     interest of the Fund or any securities thereof. Shareholders of the Funds
     may remove trustees by a vote of two-thirds of the eligible shares.

     Neither the Equity Fund nor the Large-Cap Growth Fund regularly holds
     shareholder meetings. The Declaration of Trust of each Fund provides 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 Equity Fund and of the rights these shareholders will have following
     the Reorganization as holders of new Class A shares of the Large-Cap Growth
     Fund. It is not a complete description of the Declarations of Trust or the
     By-Laws of the Funds, or the applicable Delaware or Massachusetts law.
     Shareholders desiring additional information about those documents and
     provisions of law should refer to such documents and provisions.



ADDITIONAL INFORMATION

     This Combined Prospectus/Proxy Statement is being furnished in connection
     with the solicitation of proxies by the Equity Fund's Board of Trustees in
     connection with the meeting of shareholders. It is expected that the
     solicitation of proxies will be primarily by mail. Officers and service
     contractors of the Equity Fund also may solicit proxies by telephone,
     facsimile or personal interview. Authorizations for another person to
     execute proxies may be obtained by telephonic or electronically transmitted
     instructions in accordance with procedures designed to authenticate the
     shareholder's identity. In all cases where a telephonic proxy is solicited,
     the shareholder will be asked to provide his or her address, Social
     Security Number (in the case of an individual) or taxpayer identification
     number (in the case of an entity) and the number of shares owned and to
     confirm that the shareholder has received the Combined Prospectus/Proxy
     Statement and proxy card in the mail. Within 72 hours of receiving a
     shareholder's telephonic or electronically transmitted voting instructions,
     a confirmation will be sent to the shareholder to ensure that the vote has
     been taken in accordance with the shareholder's instructions and to provide
     a telephone number to call immediately if the shareholder's instructions
     are not correctly reflected in the confirmation. Shareholders requiring
     further information as to telephonic or electronically transmitted voting
     instructions or the proxy generally should contact the Equity Fund
     toll-free at 1-800-426-1130. Any shareholder giving a proxy may revoke it
     at any time before it is exercised by submitting to the Equity Fund the
     written notice of revocation or subsequently executed proxy, or by
     attending the meeting and voting in person.

     As of the Record Date, there were 1,920,729.50 outstanding shares of the
     Equity Fund and 1,590,781.83 outstanding shares of the Large-Cap Growth
     Fund. As of the Record Date, the officers and trustees of the Funds
     beneficially owned as a group less than 1% of the outstanding shares of
     each of the Equity Fund and the Large-Cap Growth Fund. To the best
     knowledge of the Board of Trustees of the Equity Fund, as of the Record
     Date, other than as set forth below, no shareholder or group (as that term
     is used in Section 13(d) of the Securities Exchange Act of 1934, as amended
     (the Exchange Act)) owned beneficially or of record more than 5% of the
     outstanding shares of the Equity Fund.

APPENDIX

AGREEMENT AND PLAN OF REORGANIZATION

     THIS AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made as of
     this 31st day of March, 2000, by and between Lord Abbett Large-Cap Growth
     Fund (the "Acquiring Fund"), a Delaware business trust, and Lord Abbett
     Equity Fund (the "Acquired Fund"), a Massachusetts business trust.

     WHEREAS, this Agreement is intended to be and is adopted as a plan of
     reorganization within the meaning of Section 368(a) 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 A
     shares of beneficial interest of the Acquiring Fund (the "Acquiring Fund
     Class A Shares" and each an "Acquiring Fund Class A Share") and the
     assumption by the Acquiring Fund of all of the liabilities of the Acquired
     Fund and the distribution, on or after the Closing Date herein referred to,
     of Acquiring Fund Class A Shares to the shareholders of the Acquired Fund
     in termination of the Acquired Fund, all upon the terms and conditions
     hereinafter set forth in this Agreement;

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

     WHEREAS, the Acquired Fund owns securities that generally are of the
     character in which the Acquiring Fund is permitted to invest;

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

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

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

   1.  REORGANIZATION

     1.1  Subject to the terms and conditions herein set forth and on the basis
          of the representations and warranties contained herein, the 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, 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) assume all of the liabilities of the Acquired
          Fund. Such transactions shall take place at the closing provided for
          in paragraph 3.1 (the "Closing").

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

                                                                     Appendix A1

<PAGE>

          (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 before 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 that do not conform to the Acquiring Fund's investment
               objectives, policies and restrictions. In the event that the
               Acquired Fund holds any investments that the Acquiring Fund may
               not hold, the Acquired Fund will dispose of such securities
               before 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, on or as soon after the Closing Date as
          is 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
          respective pro rata 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 Class A 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 terminated by a
          majority of the Acquired Fund's Trustees' executing an instrument
          pursuant to Section 5.4 of the Declaration and Agreement of Trust of
          the Acquired Fund terminating the Acquired Fund. 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 termination of the Acquired Fund.

   2.  VALUATION

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

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

A2 Appendix

<PAGE>

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

   3.  CLOSING AND CLOSING DATE

     3.1  The Closing Date shall be May 31, 2000, 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 90 Hudson Street, Jersey City, New
          Jersey, or at such other time and/or place as the parties may agree.

     3.2  In the event that on the Valuation Time (a) the NYSE or another
          primary trading market for portfolio securities of the Acquiring Fund
          or the 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
          before 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 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.

   4.  REPRESENTATION AND WARRANTIES

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

          (a)  The Acquired Fund is a registered investment company classified

               registration with the Securities and Exchange Commission (the
               "Commission") as an investment company under the Investment
               Company Act is in full force and effect.

          (b)  The Acquired Fund is duly organized, validly existing and in good
               standing under the laws of the State of Massachusetts and has the
               power to own all of its properties and assets and to carry out
               this Agreement.

          (c)  The current prospectus and statement of additional information of
               the Acquired Fund conform (and any prospectus or statement of
               additional information of the Acquired Fund issued before the
               Closing Date will conform) in all material respects to the
               applicable requirements of the Securities Act of 1933, as amended
               (the "Securities Act"), and the Investment Company Act and the
               rules and
                                                                     Appendix A3

<PAGE>

               regulations of the Commission thereunder and do not (and will
               not) include any untrue statement of a material fact or omit to
               state any material fact required to be stated therein or
               necessary to make the statements therein, in light of the
               circumstances under which they were (and will be) made, not
               materially misleading.

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

          (e)  The Acquired Fund has no material contracts or other commitments
               that will be terminated with liability to the Acquired Fund on,
               before or after the Closing Date.

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

          (g)  True and correct copies of the Acquired Fund's (i) Statement of
               Net Assets as at May 31, 1999 and (ii) Statements of Operations
               and Changes in Net Assets for the 12-month period then ended,
               including the accompanying notes, have been furnished to the
               Acquiring Fund. Such Statement of Net Assets and such Statements
               of Operations and Changes in Net Assets (and the accompanying
               notes) have been audited by Deloitte & Touche LLP, independent
               certified public accountants. Such statements have been prepared
               in accordance with generally accepted accounting principles
               consistently applied, and such statements fairly reflect the
               financial condition and the operations and changes in net assets
               of the Acquired Fund as of such date and for such period,
               respectively. There are no known contingent liabilities of the
               Acquired Fund as of such date required to be reflected or
               disclosed in such Statement of Net Assets or notes in accordance
               with generally accepted accounting principles that are not so
               reflected or disclosed.

          (h)  Since May 31, 1999, 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 Acquired Fund will file its final federal and other tax
               returns for the period ending on the Closing Date in accordance
               with the Code. At the Closing Date, all federal and other tax
               returns and reports of the Acquired Fund required by law to have
               been filed before the Closing Date shall have been filed, and all
               federal and other taxes shown as due on such returns shall have
               been paid, or provision shall have been made for the payment
               thereof, and to the best of the Acquired 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 Acquired
               Fund has met the requirements of Subchapter M of the Code for
               qualification and treatment as a regulated investment company.

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

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

          (m)  The execution, delivery and performance of this Agreement has
               been duly authorized by all necessary action on the part of
               Acquired Fund'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 Acquired Fund
               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
               Acquired Fund's Board of Trustees has called a meeting of the
               Acquired Fund's shareholders at which the shareholders of the
               Acquired Fund are to consider and act upon this Agreement.

          (n)  The information furnished and to be furnished by the Acquired
               Fund for use in registration statements, proxy materials and
               other documents that 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 Acquired Fund 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 A Shares to be issued to the Acquired
               Fund hereunder are not being acquired for the purpose of making
               any distribution thereof other than in accordance with the terms
               of this Agreement.

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

          (a)  The Acquiring Fund is a registered investment company classified
               as a management company of
                                                                     Appendix A5

               force and effect.

          (b)  The Acquiring Fund is duly organized, validly existing and in

               power to own all of its properties and assets and to carry out
               this Agreement.

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

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

          (e)  The Acquiring Fund has no material contracts or other commitments
               that will be terminated with liability to the Acquiring Fund on,
               before or after the Closing Date.

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

          (g)  True and correct copies of the Acquiring Fund's Statement of Net
               Assets as at December 14, 1999 including the accompanying notes,
               have been furnished to the Acquired Fund. Such Statement of Net
               Assets (and the accompanying notes) have been audited by Deloitte
               & Touche LLP, independent certified public accountants. Such
               statements have been prepared in accordance with generally
               accepted accounting principles consistently applied, and such
               statements fairly reflect the financial condition and the
               operations and changes in net assets of the Acquiring Fund as of
               such date and for such period, respectively. There are no known
               contingent liabilities of the Acquiring Fund as of such date
               required to be reflected or disclosed in such Statements of Net
               Assets or notes in accordance with generally accepted accounting
               principles that are not so reflected or disclosed.

          (h)  Since December 14, there has not been any material adverse change
               in the Acquiring Fund's financial condition, assets, liabilities
               or business other than changes occurring in the ordinary course
               of business, or any incurrence by the Acquiring Fund 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 Acquiring Fund required by law to have been filed
               before the Closing Date shall have been filed, and all federal
               and other taxes

<PAGE>

               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 Acquiring Fund's knowledge, no such return is
               currently under audit and no assessment has been asserted with
               respect to such returns.

          (j)  The Acquiring Fund intends to meet the requirements of Subchapter
               M of the Code for qualification and treatment as a regulated
               investment company.

          (k)  All issued and outstanding shares of the Acquiring Fund are, and
               at the Closing Date will be, duly and validly issued and
               outstanding, fully paid and non-assessable, with no personal
               liability attaching to the ownership thereof. The Acquiring Fund
               does not have outstanding any options, warrants or other rights
               to subscribe for or purchase any shares of the Acquiring Fund,
               nor is there outstanding any security convertible into shares of
               the Acquiring Fund.

          (l)  At the Closing Date, the Acquiring Fund will have good and
               marketable title to the Acquiring Fund's assets.

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

          (n)  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.

          (o)  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 Board of Trustees of the Acquiring
               Fund, and, when issued and delivered at the Closing in accordance
               with this Agreement, will be duly and validly issued Acquiring
               Fund Class A Shares and will be fully paid and non-assessable
               with no personal liability attaching to the ownership thereof.

          (p)  The Board of Trustees of the Acquiring Fund has duly adopted a
               resolution (a copy of which has been furnished to the Acquired
               Fund) authorizing the issuance of Acquiring Fund Class A Shares
               pursuant to this Agreement.

               loss on the receipt of Class A shares of the Large-Cap Growth
               Fund (including any fractional share interests to which they may
               be entitled) solely in exchange for their Equity Fund shares.

               shareholder may be entitled) will include the period that the
               shareholder held the Equity Fund shares exchanged therefor,
               provided that the shareholder held such shares as a capital asset
               on the date of the exchange.

     8.6  The Acquiring Fund and the Acquired Fund (i) shall not be affiliated
          persons of each other, or affiliated persons of such persons, except

                                    The Fund

Goal / Principal Strategy

     The Fund's investment objective is long-term capital growth.

     Under normal circumstances,  the Fund will invest at least 65% of its total
     assets in equity  securities of large,  established  companies  with market
     capitalizations of at least $8 billion.  To identify  attractive  companies
     for investment,  the Fund uses a "bottom up" investment  research  approach
     that seeks to identify  individual  companies with expected earnings growth
     potential  and  consistency  that may not be  recognized  by the  market at
     large. This approach is based on the following steps:

     o    We  identify  large-capitalization  companies  with  at  least  a  10%
          consistent, sustainable growth rate;

     o    We  focus on  those  companies  demonstrating  a  positive  historical
          performance as well as favorable earnings prospects for the future;

     o    We focus on companies also demonstrating successful strategic business
          plan selection,  strategy and execution,  reflecting strong management
          leadership; and

     o    We focus on companies demonstrating  leadership positions within their
          industries.

     The Fund maintains a long-term investment approach,  generally expecting to
     hold stocks for an average of over three years.  This strategy supports our
     style  of  reaping  the  rewards  of  successful,  well-run  companies  and
     investing in seasoned  managements  for the long term.  The Fund may take a
     temporary  defensive position by investing some of its assets,  most likely
     not more than 30%, in  short-term  debt  securities.  This could reduce the
     benefit from any upswing in the market and prevent the Fund from  achieving
     its investment objective.

Main Risks

     The Fund is subject to the general risks and considerations associated with
     equity  investing,  as well as the particular  risks associated with growth
     stocks.  The  value  of your  investment  will  fluctuate  in  response  to
     movements in the stock  market in general and to the changing  prospects of
     individual  companies  in which the Fund  invests.  Growth  stocks may grow
     faster than other  stocks and may be more  volatile.  In  addition,  if the
     Fund's  assessment of a company's  potential for growth is wrong, the price
     of the  company's  stock  may  decrease  below  the price at which the Fund
     purchased the stock. An investment in the Fund is not a bank deposit and is
     not insured or guaranteed by the Federal Deposit  Insurance  Corporation or
     any other government agency. The Fund is not a complete  investment program
     and may not be  appropriate  for all  investors.  You could  lose  money by
     investing in the Fund.

We or the Fund refers to the Lord Abbett Large-Cap Growth Fund.

About the Fund. The Fund is a professionally managed portfolio primarily holding
securities purchased with the pooled money of investors. It strives to reach its
stated goal,  although as with all mutual funds,  it cannot  guarantee  results.

Large   companies  are   established   companies  that  are  considered   "known
quantities." Large companies often have the resources to weather economic shifts
although they can be slower to innovate than small companies.

Bottom-up  research  looks for  high-performing  stocks of individual  companies
before considering the impact of economic trends.  Companies might be identified
from investment  research  analysis or personal  knowledge of their products and
services.  This approach considers that a company can do well even if it is part
of an industry that, as a whole,  is not  performing  well.

You should read this entire prospectus, including "Other Investment Techniques,"
which concisely  describes the other investment  strategies used by the Fund and
their risks.

(1)  A  contingent  deferred  sales  charge of 1.00% may be  assessed on certain
     redemptions of class A shares made within 24 months following any purchases
     made without a sales charge.
(2)  Class B shares will convert to class A shares on the eighth  anniversary of
     your original purchase of class B shares.
(3)  The annual  operating  expenses  are based on  estimated  expenses  for the
     current fiscal year.
(4)  Because 12b-1 fees are paid out on an on-going  basis,  over time they will
     increase  the cost of your  investment  and may cost you more  than  paying
     other types of sales charges.

Example

This  Example is intended to help you compare the cost of  investing in the Fund
with the cost of investing in other mutual  funds.  This  Example,  like that in
other  funds'  prospectuses,  assumes  that you  invest  $10,000  in the Fund at
maximum sales charge, if any, for the time periods indicated and then redeem all
of your shares at the end of those  periods.  The Example also assumes that your
investment  has a 5% return  each year and that the  Fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your costs (including any applicable contingent deferred sales
charges) would be:

SHARE CLASS                                          1 YEAR           3 YEARS
Class A shares                                        $714             $1,007

- --------------------------------------------------------------------------------
Class B shares                                        $713             $ 958
- --------------------------------------------------------------------------------
Class C shares                                        $313             $ 658
Class P shares                                        $158             $ 490

You would pay the following expenses if you
did not redeem your shares:

Class A shares                                        $714             $1,007

Class B shares                                        $213             $ 658
Class C shares                                        $213             $ 658

Class P shares                                        $158             $ 490

Management fees are payable to Lord, Abbett & Co. ("Lord Abbett") for the Fund's
investment management.

12b-1 fees refer to fees incurred for activities that are primarily  intended to
result in the sale of Fund  shares  and  service  fees for  shareholder  account
service and  maintenance.

Other  expenses  include fees paid for  miscellaneous  items such as shareholder
service fees and professional fees.


                                                                      The Fund 3


<PAGE>

Purchases

     The Fund offers in this prospectus four classes of shares: classes A, B ,C,
     and P, each with different expenses and dividends.  You may purchase shares
     at the net asset value  ("NAV") per share  determined  after we receive
     your  purchase  order  submitted in proper  form. A front-end  sales
     charge is added to the NAV in the case of the  class A shares.  There is no
     front-end  sales  charge in the case of the  class B and C shares  although
     there is a contingent  deferred sales charge  ("CDSC") as described  below.
     You should read this section  carefully to determine  which class of shares
     represents the best investment option for your particular situation. It may
     not be  suitable  for you to place a  purchase  order for class B shares of
     $500,000 or more or a purchase  order for class C shares of  $1,000,000  or
     more.   You  should   discuss   purchase   options  with  your   investment
     professional.

     For more information, see "Alternative Sales Arrangements" in the Statement
     of Additional Information.

     We reserve the right to withdraw  all or any part of the  offering  made by
     this  prospectus or to reject any purchase order. We also reserve the right
     to waive or change minimum investment requirements. All purchase orders are
     subject to our acceptance  and are not binding until  confirmed or accepted
     in writing.

NAV per share for each class of Fund shares is  calculated  each business day at
the close of regular trading on the New York Stock Exchange  ("NYSE"),  normally
4:00 p.m.  Eastern time.  Purchases and sales of Fund shares are executed at the
NAV  next  determined  after  the Fund  receives your  order in proper form. In
calculating NAV, securities for which market quotations are available are valued
at those quotations.  Securities for which such quotations are not available are
valued at fair value under procedures approved by the Board.

- --------------------------------------------------------------------------------
(1)  The  anniversary is the same calendar day in each respective year after the
     date of purchase.  For example,  the  anniversaries for shares purchased on
     May 1 will be May 1 of each succeeding year.
(2)  Class B shares will  automatically  convert to class A shares on the eighth
     anniversary of the purchase of class B shares.

     The  class B share  CDSC  generally  will be  waived  under  the  following
     conditions:

     o    benefit  payments  under  Retirement  Plans  such as  loans,  hardship
          withdrawals, death, disability, retirement, separation from service or
          any excess contribution or distribution under Retirement Plans

     o    Eligible  Mandatory  Distributions  under 403(b) Plans and  individual
          retirement accounts

     o    death of the shareholder

     o    redemptions  of shares in  connection  with  Div-Move  and  Systematic
          Withdrawal Plans (up to 12% per year)

     See  "Systematic  Withdrawal  Plan" under "Services For Fund Investors"
     below for more information on CDSCs with respect to class B shares.

     CLASS C SHARE CDSC. The 1% CDSC for class C shares normally  applies if you
     redeem your shares before the anniversary of the purchase of such shares.

     CLASS P SHARES.  Class P shares have lower annual expenses than class B and
     class C shares, no front-end sales charge,  and no CDSC. Class P shares are
     currently  sold and redeemed at NAV (a) pursuant to a Mutual Fund Fee Based
     Program, or (b) to the trustees of, or  employer-sponsors  with respect to,
     pension or retirement plans with at least 100 eligible employees (such as a
     plan under Section 401(a),  401(k) or 457(b) of the Internal  Revenue Code)
     which engage an investment  professional  providing or  participating in an
     agreement  to  provide   certain   recordkeeping,   administrative   and/or
     sub-transfer  agency  services  to  the  Fund  on  behalf  of the  class  P
     shareholders.

Sales Compensation

     As part of its  plan for  distributing  shares,  the  Fund and Lord  Abbett
     Distributor pay sales and service  compensation to Authorized  Institutions
     that sell the Fund's shares and service its shareholder accounts.

     Sales compensation originates from two sources, as shown in the table "Fees
     and Expenses":  sales charges which are paid directly by shareholders;  and
     12b-1 distribution and service fees

CDSC,   regardless  of  class,  is  not  charged  on  shares  acquired   through
reinvestment of dividends or capital gains  distributions  and is charged on the
original  purchase  cost or the current  market  value of the shares at the time
they are being sold, which-ever is lower. In addition,  repayment of loans under
Retirement  Plans and 403(b)  Plans will  constitute  new sales for  purposes of
assessing the CDSC.


To minimize  the amount of any CDSC,  the Fund redeems  shares in the  following
order:

1.   shares acquired by reinvestment of dividends and capital gains (always free
     of a CDSC)

2.   shares held for six years or more (class B) or one year or more (class C)

3.   shares  held the longest  before the sixth  anniversary  of their  purchase
     (class B) or before the first anniversary of their purchase (class C)


6 Your Investment


<PAGE>



     that are paid out of the Fund's  assets.  Service  compensation  originates
     from 12b-1 service fees.  The 12b-1 fees payable with respect to each share
     class are .35% of class A shares,  1.00% of class B and C shares,  and .45%
     of class P shares.  The  amounts  payable  as  compensation  to  Authorized
     Institutions,  such as your  dealer,  are  shown in the chart at the end of
     this  prospectus.  The  portion of such  compensation  paid to Lord  Abbett
     Distributor is discussed under "Sales Activities" and "Service Activities."
     Sometimes we do not pay  compensation  where tracking data is not available
     for certain accounts or where the Authorized Institution waives part of the
     compensation.  In such cases,  we may not require  payment of any otherwise
     applicable CDSC.

     We may pay Additional  Concessions to Authorized  Institutions from time to
     time.

     SALES  ACTIVITIES.  We may use 12b-1  distribution  fees to pay  Authorized
     Institutions to finance any activity which is primarily  intended to result
     in the sale of shares.  Lord  Abbett  Distributor  uses its  portion of the
     distribution  fees  attributable to a fund's class A and class C shares for
     activities which are primarily intended to result in the sale of such class
     A and class C shares,  respectively.  These activities include, but are not
     limited  to,  printing  of   prospectuses   and  statements  of  additional
     information and reports for other than existing  shareholders,  preparation
     and distribution of advertising and sales material,  expenses of organizing
     and  conducting  sales  seminars,   Additional  Concessions  to  Authorized
     Institutions,  the cost necessary to provide distribution-related  services
     or  personnel,  travel,  office  expenses,  equipment  and other  allocable
     overhead.

     SERVICE   ACTIVITIES.   We  may  pay  12b-1   service  fees  to  Authorized
     Institutions  for any  activity  which is  primarily  intended to result in
     personal  service  and/or the  maintenance  of  shareholder  accounts.  Any
     portion of the service fees paid to Lord Abbett Distributor will be used to
     service and maintain shareholder accounts.

that  fee.  If Lord  Abbett  Distributor's  expenses  are  less  than the fee it
receives, Lord Abbett Distributor will keep the full amount of the fee.

EXCHANGE  LIMITATIONS.  Exchanges should not be used to try to take advantage of
short-term swings in the market.  Frequent  exchanges create higher expenses for
the Fund.  Accordingly,  the Fund reserves the right to limit or terminate  this
privilege  for  any  shareholder   making  frequent  exchanges  or  abusing  the
privilege.  The Fund also may revoke the privilege for all shareholders  upon 60
days' written notice.

REDEMPTIONS

     BY BROKER.  Call your investment  professional  for  instructions on how to
     redeem your shares.

     BY  TELEPHONE.  To obtain the proceeds of a  redemption  of $50,000 or less
     from  your  account,  you or your  representative  should  call the Fund at
     800-821-5129.

     BY MAIL.  Submit a written  redemption  request  indicating  the name(s) in
     which the account is registered, the Fund's name, the class of shares, your
     account number, and the dollar value or number of shares you wish to sell.

     Include all necessary signatures. If the signer has any Legal Capacity, the
     signature and capacity must be guaranteed by an Eligible Guarantor. Certain
     other legal documentation may be required.  For more information  regarding
     proper documentation call 800-821-5129.

     Normally a check  will be mailed to the  name(s)  and  address in which the
     account is registered (or otherwise  according to your instruction)  within
     three business days after receipt of your redemption request.  Your account
     balance  must be  sufficient  to cover the amount  being  redeemed  or your
     redemption order will not be processed.  Under unusual  circumstances,  the
     Fund may suspend redemptions, or postpone payment for more than seven days,
     as permitted by federal securities laws.

     To determine if a CDSC applies to a  redemption,  see "Class A share CDSC,"
     "Class B share CDSC" or "Class C share CDSC."

DISTRIBUTIONS AND TAXES

     The Fund normally pays its  shareholders  dividends from its net investment
     income and  distributes  its net capital  gains (if any) as "capital  gains
     distributions" on an annual basis. Your distributions will be reinvested in
     the Fund unless you instruct the Fund to pay them to you in cash. There are
     no sales charges on  reinvestments.  The tax status of distributions is the
     same for all  shareholders  regardless  of how long  they have  owned  Fund
     shares or whether distributions are reinvested or paid in cash.

     Except in tax-advantaged accounts, any sale, redemption or exchange of Fund
     shares may be taxable to the shareholder.

     Information on the tax treatment of distributions,  including the source of
     dividends and distributions of capital gains by the Fund, will be mailed to
     shareholders  each year.  Because  everyone's tax situation is unique,  you
     should  consult your tax adviser  regarding the treatment of  distributions
     under the federal, state and local tax rules that apply to you.

SMALL ACCOUNTS.  Our Board may authorize  closing any account in which there are
fewer  than 25  shares if it is in the Fund's  best  interest  to do so.

ELIGIBLE GUARANTOR is any broker or bank that is a member of the medallion stamp
program.  Most major securities  firms and banks are members of this program.  A
notary public is not an eligible guarantor.

     1997, a team of investment professionals at Chase Manhattan Bank,
     including Mr. Humphrey, was responsible for the management of the fund's
     portfolio.

     The  cumulative  total  return for the Chase Vista  Select Large Cap Growth
     Fund from March 17, 1997 through  July 31, 1999 was 109.01%.  At July 31,
     1999,  this fund had $825.2  million in net  assets.  As shown in the table
     below,  average annual total returns for the one year period ended July 31,
     1999 and for the  period  during  which Mr.  Humphrey  managed  that  fund,
     compared with the  performance  of the Standard & Poor's  500(R)  Composite
     Stock Price Index ("S&P 500(R) Index") and the Lipper Large Cap Growth Fund
     average, were:

(a)  Average  annual  total  return   reflects   changes  in  share  prices  and
     reinvestment of dividends and distributions and is net of fund expenses.
(b)  The S&P 500 Index is an unmanaged index of common stocks that is considered
     to be generally representative of the United States stock market. The Index
     is adjusted to reflect reinvestment of dividends.
(c)  The average annual total return for the period from March 17, 1997
     through July 31, 1999 was 35.52%.
(d)  This  percentage  represents  the average  annual  return of the S&P 500(R)
     Index  during the period from March 20, 1997 through July 31, 1999
     that Mr.  Humphrey  managed the Chase Vista Select Large Cap Growth Fund.
(e)  This  percentage  represents  the average annual return of the Lipper Large
     Cap Growth Fund  average  during the period from March 20, 1997 through
     July 31, 1999 that Mr.  Humphrey  managed the
     Chase Vista Select Large Cap Growth Fund.

     Historical  performance is not indicative of future  performance.  Although
     the Lord Abbett  Large-Cap Growth Fund and the Chase Vista Select Large Cap
     Growth Fund have substantially similar investment objectives,  policies and
     strategies, the Chase Vista Select Large Cap Growth Fund is a separate fund
     and its historical  performance is not indicative of the future performance
     of the Lord Abbett  Large-Cap Growth Fund. For the periods shown above, the
     anticipated expenses of the Lord Abbett Large-Cap Growth Fund may have been
     higher than the  expenses of the Chase Vista  Select Large Cap Growth Fund.
     Higher expenses,  of course,  would reduce a fund's performance.  The Chase
     Vista Select Large Cap Growth Fund was the only investment vehicle that Mr.
     Humphrey  managed during the period he was employed at Chase Manhattan Bank
     that has or had substantially similar investment  objectives,  policies and
     strategies as those of the Lord Abbett  Large-Cap Growth Fund. Share prices
     and investment returns will fluctuate reflecting market conditions, as well
     as changes in company-specific fundamentals of portfolio securities.

OTHER INVESTMENT TECHNIQUES

     This section describes some of the investment techniques that might be used
     by the Fund and their risks.

     ADJUSTING  INVESTMENT  EXPOSURE.  The Fund may, but is not required to, use
     various strategies to change its investment  exposure to adjust to changing
     security prices,  interest rates, currency exchange rates, commodity prices
     and other factors.  The Fund may use these  transactions to change the risk
     and return  characteristics  of the Fund's  portfolio.  If we judge  market
     conditions  incorrectly or use a strategy that does not correlate well with
     the Fund's investments, it could result in a loss, even if we intended to
     lessen  risk or enhance  returns.  These  transactions  may involve a small
     investment  of cash compared to the magnitude of the risk assumed and could
     produce  disproportionate  gains or losses.  Also,  these  strategies could
     result in losses if the  counterparty to a transaction  does not perform as
     promised.

     DIVERSIFICATION. The Fund is a diversified fund, which generally means that
     with  respect to 75% of its total  assets,  it will not purchase a security
     if, as a result,  more than 5% of the fund's total assets would be invested
     in  securities  of a single  issuer or the fund would hold more than 10% of
     the outstanding voting securities of the issuer. U.S. government securities
     are not subject to these requirements.

     FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS. The Fund may enter into
     financial  futures  transactions.  A financial  futures  transaction is the
     purchase or sale of an exchange-traded  contract to buy or sell a specified
     financial instrument or index at a specific future date and price. The Fund
     will not enter  into any  futures  contracts,  or options  thereon,  if the
     aggregate market value of the securities  covered by futures contracts plus
     options on such financial futures exceeds 50% of its total assets.

     OPTIONS TRANSACTIONS.  The Fund may purchase and write put and call options
     on  equity  securities  or  stock  indices  that  are  traded  on  national
     securities exchanges.

     A put  option  gives the  buyer of the  option  the right to sell,  and the
     seller of the option  the  obligation  to buy,  the  underlying  instrument
     during the option  period.  The Fund may write only  covered put options to
     the extent  that cover for such  options  does not exceed 15% of the Fund's
     net  assets.  The Fund will not  purchase an option if, as a result of such
     purchase,  more than 10% of its total  assets would be invested in premiums
     for such options.

     A call  option  gives the  buyer of the  option  the right to buy,  and the
     writer  (seller)  of the  option the  obligation  to sell,  the  underlying
     instrument. The Fund may only sell (write) covered call options. This means
     that the Fund may only sell call options on  securities  it owns.  When the
     Fund  writes  a call  option,  it gives  up the  potential  for gain on the
     underlying  securities in excess of the exercise price of the option during
     the period that the option is open.

     RISKS  OF  FUTURES   CONTRACTS   AND  OPTIONS   TRANSACTIONS.   The  Fund's
     transactions,  if any,  in futures,  options on futures  and other  options
     involve additional risk of loss. Loss may result from a lack of correlation
     between changes in the value of these derivative instruments and the Fund's
     assets  being  hedged,  the  potential   illiquidity  of  the  markets  for
     derivative  instruments,  or the risks arising from margin requirements and
     related  leverage  factors  associated with such  transactions.  The use of
     these investment techniques


12 For More Information


<PAGE>

     also  involves  the  risk  of  loss  if Lord  Abbett  is  incorrect  in its
     expectation of fluctuations  in securities  prices.  In addition,  the loss
     that may be incurred by the Fund in entering into futures  contracts and in
     writing call options on futures is potentially unlimited and may exceed the
     amount of the premium received.

     PORTFOLIO   SECURITIES   LENDING.   The  Fund  may   lend   securities   to
     broker-dealers  and financial  institutions  as a means of earning income.
     This  practice  could  result in a loss or delay in  recovering  the Fund's
     securities  if the borrower  defaults.  The Fund will limit its securities
     loans to 5% of its total assets and all loans will be fully collateralized.

GLOSSARY OF SHADED TERMS

     ADDITIONAL CONCESSIONS. Lord Abbett Distributor may, for specified periods,
     allow  dealers to retain  the full sales  charge for sales of shares or may
     pay an additional concession to  a dealer who 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. Additional payments
     may  be  paid  from  Lord  Abbett   Distributor's  own  resources  or  from
     distribution fees received from a fund and will be made in the form of cash
     or, if permitted,  non-cash  payments.  The non-cash  payments will include
     business  seminars  at  Lord  Abbett's  headquarters  or  other  locations,
     including meals and entertainment,  or the receipt of merchandise. The cash
     payments may include payment of various business expenses of the dealer.

     In  selecting  dealers  to  execute  portfolio  transactions  for a  fund's
     portfolio,  if two or more dealers are considered capable of obtaining best
     execution,  we may prefer the dealer who has sold our shares  and/or shares
     of other Lord Abbett-sponsored funds.

     AUTHORIZED  INSTITUTIONS.  Institutions  and  persons  permitted  by law to
     receive  service  and/or  distribution  fees  under a Rule  12b-1  Plan are
     "Authorized   Institutions."  Lord  Abbett  Distributor  is  an  Authorized
     Institution.

     ELIGIBLE  FUND. An Eligible Fund is any Lord  Abbett-sponsored  fund except
     for  (1)  certain  tax-free,   single-state   funds  where  the  exchanging
     shareholder  is a resident  of a state in which such a fund is not  offered
     for sale;  (2) Lord Abbett Equity Fund;  (3) Lord Abbett  Series Fund;  (4)
     Lord Abbett U.S. Government  Securities Money Market Fund ("GSMMF") (except
     for holdings in GSMMF which are  attributable to any shares  exchanged from
     the Lord Abbett Family of funds).  An Eligible Fund also is any  Authorized
     Institution's   affiliated   money  market  fund   satisfying  Lord  Abbett
     Distributor as to certain omnibus account and other criteria.

     ELIGIBLE MANDATORY DISTRIBUTIONS.  If class B shares represent a part of an
     individual's total IRA or 403(b)  investment,  the CDSC will be waived only
     for that part of a mandatory  distribution which bears the same relation to
     the entire  mandatory  distribution as the B share  investment bears to the
     total investment.

     LEGAL CAPACITY.  With respect to a redemption request, if (for example) the
     request is on behalf of the estate of a deceased shareholder,  John W. Doe,
     by a person  (Robert  A.  Doe) who has the  legal  capacity  to act for the
     estate  of the  deceased  shareholder  because  he is the  executor  of the
     estate,  then the  request  must be  executed  as  follows:  Robert  A.Doe,
     Executor of the Estate of John W. Doe. That  signature  using that capacity
     must be guaranteed by an Eligible Guarantor.

     Similarly,  if (for example) the redemption request is on behalf of the ABC
     Corporation by a person (Mary B. Doe) that has the legal capacity to act on
     behalf  of  this   corporation,   because  she  is  the  President  of  the
     corporation, then the request must be executed as

GUARANTEED SIGNATURE. An acceptable form of guarantee would be as follows:

  In the case of the estate --

    Robert A. Doe
    Executor of the Estate of
    John W. Doe

     follows:  ABC  Corporation by Mary B.Doe,  President.  That signature using
     that capacity must be guaranteed by an Eligible  Guarantor  (see example in
     right column).

     MUTUAL FUND FEE BASED PROGRAM.  Certain  unaffiliated  authorized  brokers,
     dealers,  registered  investment  advisers or other financial  institutions
     ("entities")   who  either  (1)  have  an  arrangement   with  Lord  Abbett
     Distributor in accordance  with certain  standards  approved by Lord Abbett
     Distributor,  providing  specifically  for  the  use  of  our  shares  (and
     sometimes providing for acceptance of orders for such shares on our behalf)
     in particular  investment  products made  available for a fee to clients of
     such entities, or (2) charge an advisory, consulting or other fee for their
     services  and buy shares for their own  accounts  or the  accounts of their
     clients.

     PURCHASER.  The  term  "purchaser"  includes:  (1)  an  individual,  (2) an
     individual  and his or her spouse and children under the age of 21, and (3)
     a trustee or other fiduciary purchasing shares for a single trust estate or
     single fiduciary  account  (including a pension,  profit-sharing,  or other
     employee  benefit trust qualified under Section 401 of the Internal Revenue
     Code - more than one qualified employee benefit trust of a single employer,
     including its consolidated subsidiaries,  may be considered a single trust,
     as may qualified  plans of multiple  employers  registered in the name of a
     single bank trustee as one account),  although more than one beneficiary is
     involved.

     SPECIAL  RETIREMENT  WRAP  PROGRAM.  A program  sponsored by an  Authorized
     Institution showing one or more  characteristics  distinguishing it, in the
     opinion of Lord Abbett  Distributor, from a Mutual Fund Fee Based  Program.
     Such  characteristics  include,  among  other  things,  the  fact  that  an
     Authorized  Institution does not charge its clients any fee of a consulting
     or advisory nature that is economically  equivalent to the distribution fee
     under  the  class A 12b-1  Plan and the fact that the  program  relates  to
     participant-directed Retirement Plans.

YEAR 2000 ISSUES.  The Fund could be adversely affected if the computers used by
the Fund  and its  service  providers  do not  properly  process  and  calculate
date-related  information from and after January 1, 2000.

Lord Abbett is working to avoid such problems and has received  assurances  from
the Fund's service providers that they are taking similar steps. Of course,  the
Year 2000 problem is unprecedented and, therefore,  Lord Abbett cannot eliminate
altogether the possibility that it or the Fund will be affected.

In  addition,  companies  in  which  the Fund  invests  may  experience  similar
difficulties.  These problems could negatively  affect the value of the issuer's
securities, which in turn could impact the Fund's performance.

     Programs,  only new  sales are  eligible  and  exchanges  into the Fund are
     excluded.  Certain  purchases of class A shares are subject to a CDSC.
(4)  Class B and class C shares are subject to CDSCs.
(5)  With  respect  to  class  B,  C and  P  shares,  0.25%,  1.00%  and  0.45%,
     respectively,  of the  average  annual  net  asset  value  of  such  shares
     outstanding during the quarter (including distribution  reinvestment shares
     after  the  first  anniversary  of their  issuance)  is paid to  Authorized
     Institutions,  such as your  dealer.  These  fees  are  paid  quarterly  in
     arrears.
