ITEM 1.01 ENTRY INTO MATERIAL DEFINITIVE AGREEMENT

      On May 30, 2006, DUSA Pharmaceuticals, Inc. ("DUSA") and PhotoCure ASA
("PhotoCure") entered into a patent license agreement whereby DUSA grants a
non-exclusive license to PhotoCure under the patents DUSA licenses from PARTEQ,
the licensing arm of Queens University, Kingston, Ontario Canada for esters of
aminolevulinic acid ("ALA"). ALA is the active ingredient in DUSA's Levulan(R)
products. Furthermore, DUSA grants a non-exclusive license to PhotoCure for its
existing formulations of its Hexvix(R) and Metvix(R) (known in the United States
as Metvixia(R)) products for any DUSA patents that may issue or be licensed by
DUSA in the future. PhotoCure is obligated to pay royalties to DUSA, including a
prepaid royalty due on June 1, 2006 in the amount of One Million Dollars
($1,000,000), on net sales of its products to the extent they are covered by a
DUSA patent. The prepaid royalty is non-refundable. Until June 1, 2008, the
license for Metvixia in the United States is limited to certain activities
relating to PhotoCure's actinic keratoses and basal cell carcinoma indications.
Subject to early termination rights by either party for cause, or by DUSA in the
case of PhotoCure's bankruptcy, the term of the agreement expires when all
royalty periods have terminated which is currently expected to be September 22,
2016, the latest date of expiration of DUSA's patents. PhotoCure has the right
to grant sublicenses under certain conditions.
