Pax World Launches Three New Funds

Leader in Sustainable Investing launches Global Green, Small Cap, and International funds

PORTSMOUTH, N.H. – March 31, 2008 – Pax World Management Corp., investment adviser to Pax World Funds ("Pax"), which launched the nation's first socially responsible mutual fund in 1971, today announced that it has launched three new mutual funds: Pax World Global Green Fund, Pax World Small Cap Fund, and Pax World International Fund.

With these new funds, Pax also adds three new portfolio managers from well-respected financial institutions to its investment management team. As with all Pax World funds, the new funds will integrate environmental, social and governance (ESG) criteria into the investment process in search of better managed, more forward-thinking companies.

"There is a growing demand for investment options that integrate sustainability concerns into financial analysis and decision making," said Pax World President & CEO Joe Keefe. "With the addition of these three funds, Pax World now offers investors a choice of eight different mutual funds in a range of asset classes following a sustainable investing model."

The Pax World Global Green Fund invests in environmental leaders around the globe, across sectors and market capitalizations, and seeks to take advantage of the rapid expansion of environmental markets. Such environmental markets include alternative energy and energy efficiency; water treatment and pollution control; and waste technology and resource management. The Fund is sub-advised by London-based Impax Asset Management, one of the world's leading specialist environmental asset managers. Impax CEO Ian Simm heads the team of portfolio managers and research analysts for the Pax World Global Green Fund.

The Pax World International Fund's investment objective is to seek long-term growth of capital by investing in companies outside of the United States. The Fund is not constrained by any particular investment style or capitalization range, and may invest in growth stocks, value stocks, or both, and may be diversified across multiple sectors, industries and geographic regions. The Fund is managed by Ivka Kalus-Bystricky, who joined Pax World from State Street Global Advisors (SSgA) earlier this year. During her tenure at SSgA, she managed the International Growth Opportunities Fund and the Global Growth Opportunities Fund.

The Pax World Small Cap Fund's investment objective is to seek long-term growth of capital by investing in small companies with attractive valuations and growth prospects and strong management teams that exhibit a high degree of innovation and motivation to grow their business. The Fund is managed by Nathan Moser, CFA, who joined Pax World from Citizens Funds, a socially responsible mutual fund firm, where he was a portfolio manager and analyst.

The funds are immediately available through Pax World and will soon be available through leading brokerage platforms.
