         The laws of South Carolina provide that in any real estate foreclosure
proceeding a defendant against whom a personal judgment is taken or asked may
within thirty days after the sale of the mortgaged property apply to the court
for an order of appraisal. The statutory appraisal value as approved by the
court would be substituted for the high bid and may decrease the amount of any
deficiency owing in connection with the transaction. THE UNDERSIGNED HEREBY
WAIVES AND RELINQUISHES THE STATUTORY APPRAISAL RIGHTS WHICH MEANS THE HIGH BID
AT THE JUDICIAL FORECLOSURE SALE WILL BE APPLIED TO THE DEBT REGARDLESS OF ANY
APPRAISED VALUE OF THE MORTGAGED PROPERTY.

         IN WITNESS WHEREOF, this instrument has been executed under seal by the
parties hereto and delivered on the date and year first above written.
