Allen from the Board, effective July 14, 2011. On December 15, 2011, in order to fill this vacancy in accordance with Article III, Section 3 of the Company’s bylaws, the Board unanimously elected Anthony D. Caracciolo to serve as a member of the Board, effective immediately.

Mr. Caracciolo was formerly employed at Gilead Sciences, Inc. (“Gilead”), a research-based biopharmaceutical company that discovers, develops and commercializes innovative medicines in areas of unmet medical need, from 1997 until retiring in October of 2010. During his tenure, Mr. Caracciolo served as Senior Vice President, Manufacturing and Operations and was a senior member of Gilead’s executive committee, which was responsible for the strategic and operational direction of Gilead.

As a result of his appointment to the Board, Mr. Caracciolo will receive the same compensation that all other non-employee members of the Board receive (prorated for the period of his service as a Board member), which is currently: (i) $20,000 in annual compensation, with fifty percent of such compensation consisting of cash ($10,000) and fifty percent consisting of non-qualified stock options, (ii) between $250 to $1,000 for every Board meeting attended, depending on the length of the meeting, (iii) $2,500 for in-person attendance at the Company’s annual meeting, and (iv) annual grants of 25,000 non-qualified stock options to vest over 12 months in quarterly installments from the anniversary date of the grant, subject to the Company’s performance.

Mr. Caracciolo has not previously held any positions with the Company. Other than the compensation from the registrant set forth in the preceding paragraph, no arrangement or understanding exists between Mr. Caracciolo and any other persons, pursuant to which Mr. Caracciolo was elected as a director. In addition, no related party transactions involving Mr. Caracciolo that are reportable under Item 404(a) of Regulation S-K exist.
