ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

     All of the Issuer's securities which were acquired by Mr. Orphanos, his

common shares acquired by clients of Mr. Orphanos were paid for using funds
of the clients.  The amounts of funds paid for these securities are not
provided because these transactions have occurred over a number of years and
Mr. Orphanos would have to go to an unreasonable amount of time and expense
to provide the amount of funds paid for all of the securities.  Mr. Orphanos
was already a ten percent shareholder on January 13, 2007, when the Issuer
first became a reporting company under Section 12(g) of the Securities
Exchange Act of 1934, as amended.  He then filed a Form 3 on January 13, 2007
and his first Schedule 13 G on February 7, 2008 which reported his beneficial
ownership at those times.

ITEM 4.  PURPOSE OF TRANSACTION

     All purchases by Mr. Orphanos and by his clients were made for
investment purposes.
