        1.     Joinder. Each of TSA Services and TSA Gift Card hereby agrees as
follows in favor of the Agent and Lenders:

        (a)   Effective as of the date hereof, each New Borrower hereby agrees
to become a Borrower under, and to bind itself to the Financing Agreement and
each other Loan Document to which the Borrowers are bound generally as of the
date hereof, and, in such capacity, to jointly and severally assume and bind
itself to all debts, liabilities and obligations of the Borrowers thereunder
(including, without limitation, all Obligations).

        (b)   In furtherance but without limitation of the foregoing, as
security for the prompt payment in full of all Obligations, each of the New
Borrowers hereby pledges and grants to the Agent on behalf of the Lenders a
continuing general lien upon, and security interest in, all their Collateral. To
facilitate the foregoing grant of a security interest, each New Borrower agrees
to execute (and, if required by Agent, acknowledge) and deliver to the Agent
such instruments and agreements as the Agent may require in connection herewith,
including without limitation, UCC-1 financing statements, collateral
assignments, legal opinions, resolutions, incumbency certificates, good standing
certificates, qualifications to do business and other, related documents,
instruments, certificates or agreements as Agent may reasonably request to give
effect to this joinder of each New Borrower as a Borrower.

        (c)   To induce the Agent and Lenders to accept each New Borrower as a
Borrower, New Borrower hereby agrees to and makes each and every representation
and warranty made in the Financing Agreement and the other Loan Documents in
respect of the Borrowers generally, as fully and completely as if each New
Borrower were an original party thereto (except to the extent that such
representations and warranties relate solely to an earlier date), subject,
however, to the disclosures set forth on Schedule 1(c) attached hereto.

        2.     Conditions to the Effectiveness of this Agreement.

        (a)   Conditions Precedent. This Agreement shall not become effective

delivered by the party or parties thereto.

        (b)   Condition Subsequent. On or before January 31, 2004 (the
"Restructure Deadline"), the Borrowers shall either (i) consummate the
Restructure (including, without limitation, delivery to the Agent of the stock
certificates of TSA Michigan and New Borrowers) or (ii) tender to the Agent the
stock certificates of TSA Michigan, The Sports Authority Florida, Inc., a
Florida corporation, and Authority International, Inc., a Delaware corporation.
The failure by Borrowers to comply with the foregoing condition by the
Restructure Deadline shall constitute an Event of Default under the Financing
Agreement.

        3.     Miscellaneous.

        (a)   Effect of Agreement. All references to Borrowers in the Financing
Agreement and the other Loan Documents shall be deemed to include each New
Borrower with the same force and effect as if each New Borrower were an original

this Agreement. This Agreement shall be considered a Loan Document.

        (b)   Reaffirmation of Representations and Warranties. Subject to the
disclosures set forth on Schedule 1(a), each Existing Borrower hereby ratifies
and reaffirms all of the representations and warranties set forth in the
Financing Agreement and the other Loan Documents, except to the extent that such
representations and warranties relate to an earlier date.

        (c)   Ratification. Each Existing Borrower hereby restates, ratifies and
reaffirms each and every term and condition set forth in the Financing Agreement
and the Loan Documents effective as of the date hereof.

        (d)   Estoppel. To induce the Agent and Lenders to enter into this
Agreement, Borrowers hereby acknowledge and agree that, as of the date hereof,

any Borrower in respect to any Obligations.

        (e)   Governing Law. This Agreement shall be governed by, and construed
in accordance with, the laws of the State of California and all applicable
federal laws of the United States of America.

reasonable costs and expenses of the Agent in connection with the preparation,
execution, delivery and enforcement of this Agreement and all other agreements
and instruments executed in connection herewith, including, without limitation,
the reasonable fees and out-of-pocket expenses of the Agent's counsel and the
cost of any searches respecting the New Borrowers or their assets.

        (g)   Counterparts; Effectiveness. This Agreement may be executed in any
number of counterparts and by different parties on separate counterparts,
including by facsimile signature, each of which when so executed and delivered
