The Fund's Investor Advantage
- --------------------------------------------------------------------------------
o Investors participate in an actively-managed mutual fund of small
company stocks. Small stocks, on average, have provided better
long-term returns than large company stocks;
o Extensive fundamental research helps uncover small, dynamic
companies, many highly specialized, which we believe are positioned
to exploit fast-growing sectors in the economy;
o A proven record: the Fund produced better returns than the average
small company growth fund and the unmanaged S&P 500 over the last 3
and 5 years, respectively. (3)

$1,000; $250 for IRAs

THE FUND'S INVESTMENT STRATEGY
Lord Abbett Developing Growth Fund focuses on:
o Companies with above-average, long-term growth rates, strong
management and a proven commitment to growth;
o Companies with exciting prospects, many in unique new markets, with
tremendous potential (many have patents, copyrights or special
licensings);
o Companies with undervalued assets that, despite having a strong
proprietary position, are overlooked by investors.
