                         Macromedia and Allaire Provide
                       Updated Guidance for March Quarter

                Companies Expect Merger to Close by End of March

SAN FRANCISCO, CA and NEWTON, MA -- MARCH 5, 2001 - Macromedia, Inc.
(NASDAQ:MACR) and Allaire Corporation (NASDAQ:ALLR) announced today that they
have been granted early termination of the waiting period under the
Hart-Scott-Rodino Antitrust Improvement Act. The companies now expect to close
their pending merger on or shortly after March 20, 2001, assuming approval of
the merger by Allaire stockholders at a special meeting to be held on March 20,
2001.

"We are very excited to be able to put these two companies together," said Rob
Burgess, Macromedia chairman and chief executive officer. "This merger is a huge
win for our customers, bringing together Macromedia's industry leading Web
content creation software with Allaire's application servers and application
development solutions. Our visions for the future of the Web are completely
aligned."

"While we are very confident in our product strategy and competitive position,
the weakness in the overall economy is affecting the short term results of both
companies," said Burgess.

Based on preliminary information, Macromedia expects its standalone revenue for
the quarter ended March 31, 2001 to be in the range of $85 to $90 million.
Because the merger is expected to close on or about March 20, 2001, Macromedia
will incorporate approximately the last 10 days of Allaire's March quarter into
Macromedia's reported results. Allaire will not be reporting a standalone March
quarter. Macromedia expects the inclusion of Allaire's results for this period
to be neutral to its earnings.

The combined company, which will operate under the name Macromedia, is scheduled
to report fourth quarter and fiscal year end results during the first week of
May, 2001.

Certain matters discussed in this news release, such as the expected closing
date of the merger and the short- and long-term outlooks for the combined
company, may be considered forward looking statements that involve risks and
uncertainties, including those related to the risk of integrating newly acquired
technologies and products, quarterly fluctuations of operating results, risks
related to whether the merger closes and related integration and successful
operation of the combined company, customer acceptance of new products and
services and new versions of existing products, impact of competition, risks of
delay in product development and release dates, risks of product returns,
economic conditions, including the demand for the combined company's products,
in the domestic and significant international markets, investments in new
business opportunities and the other risks detailed from time to time in the
companies' SEC reports, including without limitation their quarterly reports on
Form 10-Q and annual reports on Form 10-K as they may be updated or amended with
future filings. The actual results the companies achieve may differ materially
from any forward- looking statements due to such risks and uncertainties.
