This presentation contains "forward-looking statements" as that term is
defined under the Private Securities Litigation Reform Act of 1995 (PSLRA),
including statements regarding expectations, beliefs or intentions regarding
our business, technologies and products strategies or prospects. Actual
results may differ from those projected due to a number of risks and
uncertainties, including, but not limited to, the possibility that some or all of
the pending matters and transactions being considered by the Company may not
proceed as contemplated, and by
all other matters specified in Company's filings with the Securities and Exchange
Commission, as well as risks inherent in funding, developing and obtaining
regulatory approvals of new, commercially-viable and competitive
products and product candidates. Sufficiency of the data for approval with
respect to Cynviloq™ will be a review issue after NDA filing.
These statements are made based upon current expectations that are subject
to risk and uncertainty and information available to the Company as of the
date of this presentation. The Company does not undertake to update
forward-looking statements in this presentation to reflect actual
results, changes in assumptions or changes in other factors affecting such
forward-looking information. Assumptions and other information that
could cause results to differ from those set forth in the
forward-looking information can be found in the Company's filings with the
Securities and Exchange Commission, including its most recent periodic report. We
intend that all forward-looking statements be subject to the
safe-harbor provisions of the PSLRA. Safe Harbor Statement
