Capitalized terms used herein and not defined herein have the respective meanings assigned such terms in the Offer to Purchase and the Schedule TO.

ITEM 11.   ADDITIONAL INFORMATION

Item 11(a)(5) is hereby amended by adding the following to the end of such section:

“On June 22, 2007, the Company was served with a purported class action lawsuit filed on June 7, 2007 by a purported shareholder of the Company in the Supreme Court of the State of New York, New York County, docketed as Bert Vladimir v. Bioenvision, Inc et al., Index No. 650163-2007 (the “Vladimir Action”). The Vladimir Action purports to be brought individually and on behalf of all holders of Common Shares against the Company and each of its directors. The Vladimir Action does not name the Parent or the Offeror as defendants. The Vladimir Action alleges that the Company director defendants breached their fiduciary duties to the Company’s shareholders in connection with the Offer. Based on these allegations, the Vladimir Action seeks, among other relief, injunctive relief preliminarily and permanently enjoining the Company and its directors from consummating the Merger, rescinding, to the extent already implemented, the Merger or any of the terms thereof, declaring that the Company director defendants have committed a breach of their fiduciary duties to the purported shareholder and other members of the class, and awarding plaintiff the costs and disbursements of the Vladimir Action including a reasonable allowance for plaintiff’s attorneys and experts’ fees. The purported shareholder also filed an expedited discovery proceedings motion, seeking to proceed with discovery on an expedited basis, and a memorandum of law in support of expedited discovery proceedings.

A copy of the complaint, a corrected notice of motion for expedited proceedings and the memorandum of law in support of expedited discovery proceedings in this Action are attached hereto as Exhibits (a)(5)(N), (a)(5)(O) and (a)(5)(P) and are hereby incorporated herein by reference. The foregoing description is qualified in its entirety by reference to Exhibits (a)(5)(N), (a)(5)(O) and (a)(5)(P).

On June 20, 2007, the Court of Chancery in the State of Delaware, New Castle County (the “Court”) entered an order that consolidated all Delaware actions filed to date. On June 26, 2007, in connection with the purported consolidated class action Brian Trombley et al. v. Bioenvision, Inc. et al., Consolidated Civ. A. 3008-VCP, plaintiffs voluntarily withdrew their motion for a preliminary injunction and removed the hearing thereon scheduled for June 28, 2007 from the calendar of the Court. Plaintiffs’ claims remain pending before the Court.

On June 27, 2007, the Parent issued a press release announcing the withdrawal of the motion for a preliminary injunction by the plaintiffs in the consolidated Delaware actions filed to date. The full text of the press release is filed as Exhibit (a)(5)(Q) hereto and is incorporated by reference.”
