Re:		NOTICE OF DEFAULT; Forty-Six Million Seven Hundred Twenty-Five Thousand and No/100 ($46,725,000.00) Loan (the “Loan”) between Comstock Bellemeade, L.C. (“Borrower”) and Bank of America, N.A. (“Lender”) which Loan is guaranteed by Comstock Homebuilding Companies, Inc. (“Guarantor”)

Dear Mr. Clemente:

     This firm represents the Lender in connection with the above-referenced Loan which is secured by certain property owned by the Borrower located in Loudoun County, Virginia. In accordance with the terms of Section 1 of that certain Deed of Trust Note dated September 28, 2005 (the “Note”), Borrower is obligated to make payments in curtailment of the outstanding principal balance of the Loan on or before certain deadlines as specified in the Note.

     Borrower received notice from Lender by invoice # 0060622969 dated September 20, 2006 that the sum of $2,757,198.00 was due on September 30, 2006 (the “September Payment Deadline”). Borrower failed to pay such amount on or before the September Payment Deadline.
Therefore, Borrower is in default under the Loan.

     Lender reserves the right to pursue all remedies available to Lender under the Loan documents or at law as a result of such default. Lender further reserves the right to assess in the future, to the fullest extent provided for in the Loan documents additional legal fees, other costs of collection, interest at the default rate from and after the date hereof, and other fees, costs and charges, which may or may not be currently known to Lender (individually and collectively, the “Additional Charges”).
