GTCB’s Largest Shareholders

Below are the holdings of the largest shareholders as of
12/31/07, adjusted for the one known transaction during
2008: the conversion of LFB’s term loan into ~2M shares
of common stock. Please note that the % stakes shown
below are not the % stakes reported to the SEC but rather
the % stakes based on my calculation of 123M fully-diluted
shares outstanding for valuation purposes.

Feb 14, 2008 was the deadline for filing SEC Form-13G to show holdings as of 12/31/07 for holders with a 5-10% equity stake. (Holders with a >10% stake report holding changes within 48 hours of each transaction.)
