For the Prospectuses of the Funds and/or Series referenced above (the "Funds"),
the section entitled "Your Investment - Purchases" is being supplemented by the
addition of the information below. Where applicable, the section entitled "YOUR
INVESTMENT - SERVICES FOR FUND INVESTORS - RECORDKEEPING SERVICES" is deleted.

     REVENUE SHARING AND OTHER PAYMENTS TO DEALERS AND FINANCIAL INTERMEDIARIES.
     Lord Abbett, Lord Abbett Distributor and the Fund may make certain payments
     to dealers and other firms authorized to accept orders for Fund shares
     (collectively, "Dealers").

     Lord Abbett or Lord Abbett Distributor make payments to Dealers in its sole
     discretion, at its own expense and without cost to the Fund or the Fund's
     shareholders. The payments may be for:

          -    marketing and/or distribution support for Dealers;

          -    the Dealers' and their investment professionals' shareholder
               servicing efforts;

          -    training and education activities for the Dealers, their
               investment professionals and/or their clients or potential
               clients; and/or

                                        1


          -    the purchase of products or services from the Dealers, such as
               software tools or data for investment analysis purposes.

Some of these payments may be referred to as revenue sharing payments. Most of
these payments are intended to reimburse Dealers directly or indirectly for the
costs that they or their investment professionals incur in connection with
educational seminars and training efforts about the Lord Abbett Funds to enable
the Dealers and their investment professionals to make recommendations and
provide services that are suitable and useful in meeting shareholder needs, as
well as to maintain the necessary infrastructure to make the Lord Abbett Funds
available to shareholders. The costs and expenses related to these efforts may
include travel, lodging, entertainment and meals, among other things. In
addition, Lord Abbett Distributor may, for specified periods of time, decide to
forego the portion of any front-end sales charges to which it normally is
entitled and allow Dealers to retain the full sales charge for sales of Fund
shares. In some instances, these temporary arrangements will be offered only to
certain Dealers expected to sell significant amounts of Fund shares.

Lord Abbett or Lord Abbett Distributor, in its sole discretion, determines the
amounts of payments to Dealers, with the exception of purchases of products or
services and certain expense reimbursements. Lord Abbett and Lord Abbett
Distributor consider many factors in determining the basis or amount of any
additional payments to Dealers. The factors include the Dealer's sales, assets
and redemption rates relating to Lord Abbett Funds, penetration of Lord Abbett
Fund sales among investment professionals within the Dealer, and the potential
to expand Lord Abbett's relationship with the Dealer. Lord Abbett and Lord
Abbett Distributor also may take into account other business relationships Lord
Abbett has with a Dealer, including other Lord Abbett financial products or
advisory services sold by or provided to a Dealer or one or more of its
affiliates. Based on its analysis of these factors, Lord Abbett groups Dealers
into tiers, each of which is associated with a particular maximum amount of
revenue sharing payments expressed as a percentage of assets of the Lord Abbett
Funds attributable to that particular Dealer. The payments presently range from
0.02% to 0.1% of Lord Abbett Fund assets. The Dealers within a particular tier
may receive different amounts of revenue sharing or may not receive any. Lord
Abbett or Lord Abbett Distributor may choose not to make payments in relation to
certain of the Lord Abbett Funds or certain classes of shares of any given Fund.
In addition, Lord Abbett's formula for calculating revenue sharing payments may
be different from the formulas that the Dealers use. Please refer to the Fund's
statement of additional information for additional information relating to
revenue sharing payments.

Neither Lord Abbett nor Lord Abbett Distributor make payments directly to a
Dealer's investment professionals, but rather they are made solely to the Dealer
itself (with the exception of expense reimbursements related to the attendance
of a Dealer's investment professionals at training and education meetings and at
other meetings involving the Lord Abbett Funds). The Dealers receiving
additional payments include those that may recommend that their clients consider
or select the Fund or other Lord Abbett Funds for investment purposes, including
those that may include one or more of the Lord Abbett Funds on a "preferred" or
"recommended" list of mutual funds. In some circumstances, the payments may
create an incentive for a Dealer or its investment professionals to recommend or
sell shares of Lord Abbett Funds to a client over shares of other funds. For
more specific information about any additional payments, including revenue
sharing, made to your Dealer, please contact your investment professional.

The Fund's portfolio transactions are not used as a form of sales-related
compensation to Dealers that sell shares of the Lord Abbett Funds. Lord Abbett
places the Fund's portfolio transactions with broker-dealer firms based on the
firm's ability to provide the best net results from the transaction to the Fund.
To the extent that Lord Abbett determines that a Dealer can provide the

                                        2


Fund with the best net results, Lord Abbett may place the Fund's portfolio
transactions with the Dealer even though it sells or has sold shares of the
Fund. In no event, however, does or will Lord Abbett give any consideration to a
Dealer's sales in deciding which Dealer to choose to execute the Fund's
portfolio transactions. Lord Abbett maintains policies and procedures designed
to ensure that it places portfolio transactions based on the Fund's receipt of
the best net results only. These policies and procedures also permit Lord Abbett
to give consideration to proprietary investment research a Dealer may provide to
Lord Abbett.

In addition to the payments from Lord Abbett or Lord Abbett Distributor
described above, from time to time, the Lord Abbett Funds may enter into
arrangements with and pay fees to Financial Intermediaries that provide
recordkeeping services to certain groups of investors in the Lord Abbett Funds,
including participants in Retirement and Benefit Plans, investors in mutual fund
advisory programs, investors in variable insurance products and clients of
Financial Intermediaries that operate in an omnibus environment (collectively,
"Investors"). The recordkeeping services typically include: (a) establishing and
maintaining Investor accounts and records; (b) recording Investor account
balances and changes thereto; (c) arranging for the wiring of funds; (d)
providing statements to Investors; (e) furnishing proxy materials, periodic Lord
Abbett Fund reports, prospectuses and other communications to Investors as
required; (f) transmitting Investor transaction information; and (g) providing
information in order to assist the Lord Abbett Funds in their compliance with
state securities laws. The fees the Lord Abbett Funds pay: (1) are designed to
be equal to or less than the fees the Funds would pay to their transfer agent
for similar services; and (2) do not relate to distribution services. The Lord
Abbett Funds understand that, in accordance with guidance from the U.S.
Department of Labor, Retirement and Benefit Plans, sponsors of qualified
retirement plans and/or recordkeepers may be required to use the fees they (or,
in the case of recordkeepers, their affiliates) receive for the benefit of the
Retirement and Benefit Plans or the Investors. This may take the form of
recordkeepers passing the fees through to their clients or reducing the clients'
charges by the amount of fees the recordkeeper receives from mutual funds.
