              J. & W. Seligman & Co. Incorporated Completes IPO for
                 Seligman LaSalle International Real Estate Fund

NEW YORK, June 5, 2007 - J. & W. Seligman & Co. Incorporated announced today
that it has successfully completed the offering of Seligman LaSalle
International Real Estate Fund, Inc., a closed-end investment company. The Fund
began trading on the New York Stock Exchange (NYSE) on May 25, 2007 under the
symbol SLS. The Fund raised $222.5 million through its common share offering,
excluding the potential exercise of the underwriters' over-allotment option,
which may not occur, and before deduction of the sales load. The lead
underwriter was Citigroup Global Markets, Inc.

"Seligman LaSalle International Real Estate Fund is a unique opportunity that
offers investors a way to participate in the real estate marketplace around the
world," said Charles W. Kadlec, President of Seligman Advisors, Inc. "Seligman
selected sub-advisers with experience, expertise, and world-wide research
support." he added.

The Fund is sub-advised by LaSalle Investment Management (Securities) LP and
LaSalle Investment Management Securities BV, (together, "LaSalle Securities").
LaSalle Securities is a leading real estate securities manager and an
operationally independent subsidiary of Jones Lang LaSalle Incorporated, a
leading global property services company.

According to Michelle Rappa, Managing Director of J. & W. Seligman & Co.
Incorporated and Director of Marketing, Seligman Advisors, Inc., the newly
introduced Fund offers investors an efficient method to secure a diversified
international real estate securities portfolio. "As the global economy continues
to expand and the number of foreign REITs proliferates, investors can use the
Fund to participate in the potential growth of real estate around the world,"
she said.

The Fund's primary investment objective is long-term capital appreciation, with
current income as a secondary objective. Todd Canter, Global Strategist of
LaSalle Securities, noted that international real estate securities over time
have generated strong relative performance with lower volatility than
traditional equities (1) and often exhibit low correlations to traditional
equities and fixed-income securities. (2) He added that regional real estate
markets also tend to have low correlations with each other, which can further
enhance portfolio diversification.

Seligman LaSalle International Real Estate Fund's management team will use a
fundamentals-based, value-oriented approach to investing. "Our valuation model
has been developed and tested for 21 years and helps us identify and prioritize
promising investment opportunities globally," said Portfolio Manager, Stan
Kraska. The team's research requirements will be supported by Jones Lang
LaSalle's professional on-site presence in 125 markets, representing 50
countries across five continents.

A minimum of 80 percent of the Fund's real estate securities exposure will be
outside of the US, primarily to generate capital appreciation. To increase the
Fund's current income, the sub-advisers intend to pursue a dividend capture
strategy on the domestic component of the portfolio.

(1) The performance is based on index performance, and does not represent the
performance of the Fund. Real estate securities have had very strong relative
out-performance versus traditional common stocks and bonds. This strong
performance may not continue, and past performance is no guarantee of future
results.
