Calamos Launches Emerging Markets Fund on Global Platform (UCITS)

A Flexible, Opportunistic Approach to Investing in Emerging Economies

LONDON, May 19, 2011 - Calamos International LLP, a global investment management firm, is
pleased to announce the introduction of the Calamos Emerging Markets Fund.
Managing this Emerging Markets strategy since 2008 for investors in the U.S.,
Calamos is now offering the strategy as a UCITS.

The fund is the latest addition to the existing offerings of Global
Equity Fund, U.S. Growth Fund, Global Convertible Opportunities Fund and U.S.
Convertible Opportunities Fund of Calamos Global Funds PLC, a UCITS fund
platform. These UCITS funds are available to institutional and retail
investors outside the U.S. This new fund has already received an investment
from an institutional client in the UK.

The 1.4bn pounds Sterling Superannuation Arrangements of the University
of London (SAUL) has allocated 45 million pounds (73 million dollars) to this
strategy. Penny Green, Chief Executive of SAUL Trustee Company said: "We
chose Calamos because their approach adds a new dimension to our Emerging
Markets portfolio. They focus on revenue generation as opposed to where a
firm is domiciled, looking at economies as well as markets. Also, they take a
top-down view across a company's capital structure, rather than confining
themselves to equities. Their robust approach to risk management is a good
fit with our overall investment strategy."

The Calamos Emerging Markets Fund invests in a portfolio of companies
that the Calamos Investment Team believes is positioned to participate in the
growth of emerging economies and that the firm believes offers the best
opportunities for capital appreciation over the long term. The strategy,
available to U.S. institutional and retail investors since 2008, is a
flexible, opportunistic approach allowing the portfolio to manage risk while
seeking enhanced returns across regions, countries, market capitalization,
sectors and security type. In particular, the investment experience and use
of low-volatility equities (e.g. convertible securities) can offer the
potential to participate in rising equity markets while managing downside
risk in declining markets.

"We believe the key to consistent, long-term investment success is
pursuing an optimal balance of enhancing investment returns and managing
risk. The Calamos Emerging Markets fund shares this investment philosophy and
builds on our extensive experience of investing in global markets and
emerging economies," stated CEO and Co-Chief Investment Officer, John P.
Calamos, Sr.

The investment process for the Calamos Emerging Markets Fund and each of
the UCITS funds is based on a long record of managing similar institutional
strategies and funds for clients around the globe.
