ITEM 8.01. OTHER EVENTS.

DUSA Pharmaceuticals, Inc. ("DUSA") issued a press release on February 6, 2006
attached to and made part of this report, announcing fourth quarter (Q4) and
2005 year-end financial results. In addition, during its conference call today
discussing the results, DUSA announced that it expects that sales of the
Levulan(R) Kerastick(R) to Stiefel Laboratories, Inc. could be in the range of
300,00 - 500,000 units during the five years following launch by Stiefel.

Except for historical information, this report, including the news release,
contains certain forward-looking statements that represent our current
expectations and beliefs concerning future events, and involve certain known and
unknown risk and uncertainties. These forward-looking statements relate to
beliefs regarding fourth quarter results, intention to incorporate recent acne
results into development plans, timing of the results of the photodamage
clinical trial, timing of the closing of the pending merger, expectations for
sales to Stiefel Laboratories, Inc. and beliefs relating to gross margins being
dependent on volume. These forward-looking statements are further qualified by
important factors that could cause actual results to differ materially from
those in the forward-looking statements. These factors include, without
limitation, changing market and regulatory conditions, the clinical trial
process, the ability to obtain competitive levels of reimbursement by
third-party payors, the maintenance of our patent portfolio, foreign regulatory
approvals, dependence on third-party manufacturers, the uncertainties of the
litigation process, the ability to maintain our sales force, changes in our long
and short term goals, fluctuations in the market price of the Company's common
stock, unknown clinical trial results, the unknown sophistication of the
security holders of Sirius Laboratories, and other risks and uncertainties
