Business Wire

NEW YORK -- November 09, 2012

WeissLaw LLP, a national class action and shareholder rights law firm with
offices in New York City and Los Angeles, is investigating possible breaches
of fiduciary duty and other violations of law by the Board of Directors of
Dusa Pharmaceuticals Inc. (NASDAQ: DUSA) arising from its agreement for Dusa
to be acquired by Sun Pharmaceuticals Industries Ltd., in a cash deal valued
at approximately $230 million. Dusa shareholders will receive $8.00 per share.

WeissLaw LLP is investigating whether Dusa’s Board is acting to maximize
shareholder value for Dusa’s public shareholders in approving this deal and
whether the Board engaged in a robust sale process in shopping the company.
The $8.00 per share offer price is approximately 15% less than the $9.50 per
share price target set by an analyst. If you own Dusa shares and would like
more information about your rights as a shareholder or additional information
concerning our investigation, please contact Michael A. Rogovin either by
