Borrower is currently indebted to Lender pursuant to the terms and conditions of that certain Loan Agreement between Borrower and Lender dated as of April 30, 1998 (as amended from time to time, the "Loan Agreement"). -------------- Capitalized terms used herein and not otherwise defined shall have the meanings set forth for such terms in the Loan Agreement.

Borrower failed to maintain a Tangible Net Worth of at least $1,400,000.00 on April 30, 1999 as required by Section 8.10(a) of the Loan Agreement (the "Existing Borrower --------------- ----------------- Default"). Lender sent to Borrower and Guarantor a notice of the Existing - ------- Borrower Default on June 11, 1999 (the "Default Notice", which notice -------------- erroneously referred to Borrower's failure to maintain a Tangible Net Worth of at least $1,200,000.00 at all times during the period of January 31, 1999 through April 29, 1999), in which notice Lender informed Borrower and Guarantor, among other things, of Lender's election to apply the default interest rate (the "Default Rate") effective on the date of the Default Notice. ------------ C. W. David Sykes, an individual ("Sykes") has defaulted under that ----- certain Subordination Agreement entered into as of April 30, 1998 by Sykes in favor of Lender in connection with the Loan Agreement (as amended from time to time, the "Sykes Subordination Agreement").
