                  Date; Discontinuance of Certain Reserves)

Ladies and Gentlemen:

            We refer to that certain Loan and Security Agreement dated as of
September 30, 1999, as amended by that certain First Amendment to Loan and
Security Agreement dated as of August 16, 2001, and by that certain letter
amendment dated as of March 27, 2002 (including all exhibits and schedules
thereto, and as the same may be amended, restated, supplemented or otherwise
modified from time to time, the "Loan Agreement"), by and among Good Guys
California, Inc. ("Borrower"), the lenders signatory thereto (collectively, the
"Lenders") Bank of America, NA., as administrative agent for Lenders
("Administrative Agent"), and General Electric Capital Corporation, as
documentation agent for Lenders ("Documentation Agent," Administrative Agent and
Documentation Agent being collectively referred to as "Co-Agents"). Capitalized
terms or matters of construction defined or established in the Loan Agreement
shall be applied herein as defined or established therein.

            Borrower and Co-Agents hereby agree as follows:

            1. Amendment of Loan Agreement. The Loan Agreement is hereby
amended as follows:

                  a. The definition of "Stated Termination Date" in Section 11
of the Loan Agreement is revised by deleting "September 30, 2002" and
substituting "May 31, 2003" therefor.

                  b. Section 9.28(c) of the Loan Agreement (pertaining to a
certain reserve against the Borrowing Base to address Accounts to Online
Venture) is deleted in its entirety.

                  c. Section 4.2 of the Loan Agreement is revised as follows:

                          i. The last row in the table set forth in Section 4.2
(commencing with the text "After the first Anniversary Date . . .") is deleted
and the following is substituted therefor:

<TABLE>
<CAPTION>
------------------------------------------------------------------------------------------
PERIOD DURING WHICH EARLY TERMINATION OCCURS   EARLY TERMINATION FEE
------------------------------------------------------------------------------------------
<S>                                            <C>
After the first Anniversary Date but on or     one percent (1%) of the Average Facility

------------------------------------------------------------------------------------------
</TABLE>

                          ii. The following is added as the last sentence of
Section 4.2:

            "Notwithstanding the foregoing in this Section 4.2, no early
termination fee shall be payable if the termination of this agreement is by
reason of a renewal or extension by Co-Agents of the Total Facility or if the
termination of this Agreement prior to the Stated Termination Date occurs in the
absence of a Default or Event of Default, and with the written consent of
Co-Agents and Lenders (including termination by reason of a renewal or extension
of the Total Facility or restatement of the Loan Agreement)."

            2. Discontinuance of Retail Sales Tax Reserve. Upon the
effectiveness of this Amendment, and without limiting Administrative Agent's and
Co-Agents' discretion to reimplement such reserve or to establish additional or
increased reserves in the exercise of their reasonable credit judgment, the
"Retail Sales Tax Reserve" described in that certain "Notice Concerning
Inventory Appraisals and Reserves" dated December 3, 2001 from Co-Agents to
Borrower is discontinued.

            3. No Amendment or Waiver. Except as expressly provided herein, this
letter shall not constitute an amendment or waiver by Co-Agents of any provision
of the Loan Agreement or any other Loan Document, each of which shall remain in
full force and effect, and under which each of the Co-Agents and Lenders hereby
expressly reserves all of its respective rights.

constitute one and the same agreement. Delivery of an executed counterpart of a
signature page by facsimile transmission shall be effective as delivery of a

letter amendment by facsimile shall send the original manually executed
counterpart to Documentation Agent promptly after such facsimile transmission.
