FORWARD LOOKING STATEMENTS
The forward-looking statements contained in this announcement are based on the
management's current expectations concerning certain future events and
results. These are, of course, subject to uncertainty, and actual results may
therefore differ materially from those expressed by the statements. Further,
some of the expectations are based upon assumptions about future events, which
may turn out to be incorrect.

ADDITIONAL INFORMATION
Stockholders of Synaptic are urged to read the proxy statement that Synaptic
will file on Schedule 14A with the Securities and Exchange Commission ("SEC")
when it becomes available, and any other relevant documents filed or to be
filed in the future with the SEC because those documents contain important
information about Synaptic, the proposed transactions and related matters.
Investors and security holders can obtain free copies of the proxy statement
at Synaptic's web site, www.synapticcorp.com or by contacting Investor
Relations, Synaptic Pharmaceutical Corporation, 215 College Road, Paramus, NJ
07652 (Telephone: (201) 261-1331, ext. 1410). Investors and security holders
can also obtain free copies of the proxy statement and other documents filed
by Synaptic and henceforth by Lundbeck with the SEC in connection with the
proposed transactions at the SEC's web site at www.sec.gov.

In addition to the proxy statement, Synaptic files annual, quarterly and
special reports, proxy statements and other information with the SEC, each of
which are available at the SEC's web site at www.sec.gov. Lundbeck has not
previously filed any reports or other information with the SEC because
Lundbeck has no securities registered pursuant to the Securities Exchange Act
of 1934, as amended. You may also read and copy any reports, statements and
other information filed by Synaptic and henceforth by Lundbeck at the SEC
public reference room at 450 Fifth Street, N.W., Washington, D.C. 20549.
Please call the SEC at 1-800-SEC-0330 for further information.

Synaptic, Lundbeck, and their respective directors, executive officers and
certain members of management and other employees may be deemed to be
participants in the solicitation of proxies of Synaptic's stockholders to
approve the proposed transactions. Such individuals may have interests in the
transactions, including as a result of holding options or shares of Synaptic's
stock. Information regarding Lundbeck and its directors and officers is
contained below. Information regarding Synaptic and its directors and officers
is contained in its proxy statement on Schedule 14A, filed with the SEC on
