Supplement To The
Current Prospectus Of
Lord Abbett
Developing Growth Fund, Inc.
Class C shares of the Fund may be purchased under a mutual fund wrap-fee
program, in which case, an alternate method of first year payment may be used
pursuant to the Fund's Class C Share Rule 12b-1 Plan.
This alternate method permits the Class C Share Plan payments to be made
quarterly on average net assets, on a pro-rata basis, during the first year
subsequent to the purchase of shares, excluding dividend and distribution
reinvestments. After the first year, payments with respect to a mutual fund
wrap-fee program follow the current Plan. In addition, redemptions of shares
under such a program during the first year are not subject to a contingent
deferred sales charge.
A mutual fund wrap-fee program is for certain unaffiliated authorized
brokers, dealers, registered investment advisers or other financial institutions
who have entered into an agreement with Lord Abbett Distributor in accordance
with certain standards approved by Lord Abbett Distributor, providing
specifically for the use of the Fund's Class C shares in particular investment
products made available for a fee to clients of such brokers, dealers,
registered investment advisers and other financial institutions.
Effective Date: May 8, 1998
