NO CLASS HAS YET BEEN CERTIFIED IN THE ABOVE ACTION. UNTIL A CLASS IS CERTIFIED, YOU ARE NOT REPRESENTED BY COUNSEL UNLESS YOU RETAIN ONE. YOU MAY CHOOSE TO DO NOTHING AT THIS POINT AND REMAIN AN ABSENT CLASS MEMBER.

The lawsuit alleges that during the Class Period, the Company and certain of its executive officers misrepresented or failed to disclose that: (a) the Company's Cangrelor drug candidate, did not show superiority against a competing drug already approved by the FDA; and (b) the clinical trials which compared Cangrelor to a competing drug were unethically and inappropriately administered.

On February 10, 2014, the ("FDA") issued a report indicating that Cangrelor was not shown to be as good or superior to a rival drug and a new trial should be conducted before the drug is considered for approval. The report also states that the related trials "were conducted unethically" and Cangrelor should not be approved "on that fact alone."

If you wish to serve as lead plaintiff, you must move the Court no later than April 22, 2014. A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation.
