                  approximately 14.6 acres and improvements of approximately

                  In addition, the Bank will require either real estate with a
                  minimum equity of $1,250,000 (after first lien) or a Letter of

                  The Letter of Credit shall be drawn against if CASCO is not in

                  report or asset based audit. Closing attorney representing
                  BB&T shall approve the Letter of Credit language.
