El Segundo, CA 90245

Ladies and Gentlemen:

Reference is hereby made to that certain Financing Agreement dated March 8, 1996
and amendments thereto (the "Financing Agreement"), as and between the lenders
thereto (the "Lenders"), The CIT Group/Business Credit, Inc., as Agent for the
Lenders and a Lender ("CIT"), and Big 5 Corp., a Delaware corporation, successor
by merger to United Merchandising Corp. (the "Company"). We refer also to that
certain Seventh Amendment to Financing Agreement between CIT, the Lenders and
the Company dated April 30, 2002 (the "Seventh Amendment"). Capitalized terms
used herein and not otherwise defined herein shall have the respective meanings
set forth in the Financing Agreement.

Pursuant to mutual agreement, CIT, the Lenders and the Company hereby agree to
delete numbered paragraph 3 of the Seventh Amendment and substitute the
following in lieu thereof:

        3. Consent. Subject to the terms and conditions herein, including,
           without limitation, the Conditions to Effectiveness set forth in
           Section 4 hereof, Agent and Lenders hereby consent to Borrower
           declaring and paying one or more dividends to Parent, in an aggregate
           amount not to exceed $30,000,000, for the purposes of (i)
           repurchasing or redeeming shares of common stock and preferred stock
           of Parent; (ii) repurchasing or redeeming Parent's 13.45% Senior
           Discount Notes due 2008 (including paying all outstanding principal,
           accrued and unpaid interest and other amounts related thereto); (iii)
           paying special one-time bonuses to directors and executive officers
           of Parent in an aggregate amount not to exceed $2,600,000.00; and
           (iv) paying fees and expenses, all related to and in connection with
           the consummation of the initial public offering of the common stock
           of Parent (the "IPO"); provided, that, (a) after giving effect to the
           payment of such dividend(s), Availability is at $35,000,000 and no
           Default or Event of Default is existing or has occurred and is
           continuing and (b) such dividend(s) shall be declared and paid by
           Borrower only to the extent that net proceeds from the IPO received
           by Parent are insufficient to satisfy all of the purposes described
           above, and the aggregate amount of such dividend(s) shall not exceed
           such insufficiency. For purposes of clarity, Borrower may declare and
           pay such dividend(s) following the first closing of the IPO and prior
           to the exercise, if any, of the underwriters' over-allotment option
           with respect to the IPO; provided, however, that in such event,
           Parent shall contribute to Borrower promptly after any exercise of
           the underwriters'

           over-allotment option the net proceeds it receives upon such
           exercise, and Borrower shall use such excess net proceeds to pay down
           the Line of Credit.

Please acknowledge your receipt and acceptance of this letter by executing and
returning the enclosed copy of this letter.
