Explanation of Responses:

(1) On February 21, 2003, America First Companies L.L.C. made an in-kind distribution of 175,000 shares to its equity members. All of these shares had been previously reported as indirectly beneficially owned by Mr. Yanney due to his control of America First Companies L.L.C. Of the distributed shares, 87,232 wre distributed to Mr. Yanney, of which 19,262 were originally distributed to Gail E. Walling, Mr. Yanney's wife, and simultaneously deposited to Mr. Yanney's account; 5,858 shares were distributed to Rainwood Enterprises, L.P. and 2,430 shares were distributed to Torrey Lake Charitable Remainder Trust and continue to be reported as indirectly beneficially owned by Mr. Yanney. The remaining 79,480 shares were distributed to individuals not controlled by Mr. Yanney and, accordingly, are no longer reported as indirectly beneficially owned by him.
