<P align="left" style="font-size: 10pt; text-indent: 4%">On January&nbsp;5, 2011, Timothy Rogers, our Senior Corporate Vice President &#150; Product Development and member of our
Board of Directors, provided notice to our Chief Executive Officer of his resignation as Senior Corporate Vice
President &#150; Product Development. Mr.&nbsp;Rogers&#146; employment agreement contains a six-month notice period. Mr.&nbsp;Rogers also
provided notice of his intent to resign as a Director. On March 8, 2011, we agreed with Mr. Rogers that his
employment will cease effective April&nbsp;30, 2011. On March 17,
2011, our Board of Directors considered Mr. Rogers&#146; intention to
resign as a Director and it was agreed that  Mr. Rogers&#146;
resignation as a Director would be effective April 30, 2011,
concurrent with his termination of employment.  In connection with
Mr. Rogers&#146; resignation as a Director, our Board of Directors
also determined to reduce the size of our Board to six Directors
rather than fill the vacancy created by Mr. Rogers&#146;
resignation.  Mr.&nbsp;Rogers&#146; decision to resign his
employment and Directorship was not the result of any disagreement with our company.
