Calamos Closes Market Neutral Fund

Naperville, Illinois, UNITED STATES

NAPERVILLE, Ill., Nov. 19, 2001 (PRIMEZONE) -- Calamos Market Neutral Fund, a mutual fund that employs a convertible arbitrage strategy with an objective of high current income consistent with stability of principal, will be closed to new investors on November 30, 2001. The fund has been open since September 4, 1990.

Through October 31, the fund had $367 million in assets. Since the beginning of the year, the fund has received inflows of $303 million, an increase of 471%. The Fund's closing will facilitate the portfolio management team's ability to continue to manage the fund effectively.

"The response to the Calamos Market Neutral Fund demonstrates the strong interest in alternative investments and risk-managed investments," said John P. Calamos, President and Chief Investment Officer of Calamos Asset Management, Inc., the advisor to the fund.

Calamos is well-known for its pioneering use of convertible bonds as a risk-management tool. Several of its funds employ convertible securities, a hybrid investment vehicle that has fixed-income characteristics, which help protect investor's capital during down markets, as well as an equity component that can deliver the potential for participation in rising stock markets. Convertibles are often added to the fixed-income allocation of a portfolio, however they can also be used as a defensive equity tool. Calamos' Convertible Growth and Income Fund is ranked No. 1 convertible fund by Lipper(a) for five and 10 years out of 38 and 16 funds respectively as of September 30.

Calamos, providing investment management services for 25 years, has successfully replicated the investment discipline it employs in managing institutional portfolios in its Family of Funds. Calamos' proprietary investment process has proven effective not only in its convertible strategies, but also as applied to its equity evaluation. As of September 30, 2001, Morningstar ranked the Calamos Growth Fund No. 1 fund for three, five and 10 years out of 1,689, 964, and 283 funds respectively, out of all funds with a prospectus objective of growth(b).

Several of the Calamos Funds, including the Market Neutral Fund, have received Morningstar's(c) highest rating, five stars overall, as of September 30, 2001. Five stars were earned by the Calamos Convertible Growth and Income Fund (Nasdaq:CVTRX), Calamos Market Neutral Fund (Nasdaq:CVSIX) and Calamos Growth Fund (Nasdaq:CVGRX), all out of 4,633 domestic equity funds. As well, the Calamos Global Convertible Fund (Nasdaq:CVLOX) also received five stars out of 1,305 international equity funds.

The Market Neutral fund will remain open to new investors through November 30. After that date, only existing shareholders will be able to make additional investments. Effective November 9, 2001 the minimum initial investment is $10,000.

This is the first fund that Calamos has closed to new investors. While the firm has no definitive plans to reopen the fund in the future, re-opening the fund may be considered at a later time.

Past performance is no guarantee of future results.

In addition to market risk, there are certain risks associated with an investment in a convertible bond such as default risk (risk that the company issuing a convertible security will be unable to repay principal and interest) and interest rate risk (risk that the security may decrease in value if interest rates increase).

Investments by the CALAMOS Growth Fund in smaller companies present greater risks than investments in larger companies.

Each Fund may invest up to 25% (Global Convertible Fund up to 100%) of its assets in foreign securities which present special risk considerations such as fluctuations in foreign currencies or difficulty obtaining information.
