                                JOINDER AGREEMENT


        THIS AGREEMENT is being executed effective as of November 21, 2003 (the
"Effective Date"), by TBC CORPORATION, a Delaware corporation ("TBC"), in favor
of each of REALTY INCOME CORPORATION, a Maryland corporation ("RIC"), CREST NET
LEASE, INC., a Delaware corporation ("Crest"), and REALTY INCOME TEXAS
PROPERTIES, L.P., a Delaware limited partnership ("Texas"), and their successors
and assigns, under the following circumstances:

               A. TBC's wholly-owned subsidiary, NTW Incorporated, a Delaware
        corporation ("NTW"), is party to a series of Land and Building Lease
        Agreements, dated as of November 21, 2003 and more particularly
        described in Exhibit A attached hereto (the "Leases"), with RIC, Crest,
        and Texas (each, a "Lessor"), pursuant to the terms of which NTW leases
        a total of 86 retail tire stores from the Lessors.

               B. As a condition to the obligation of each Lessor to execute the
        Leases with NTW to which such Lessor is a party, TBC executed a series
        of Guarantys, dated as of November 21, 2003 and more particularly
        described in Exhibit B attached hereto (the "Guarantys"), pursuant to
        which TBC guaranteed to each Lessor the full and prompt payment and
        performance by NTW of all of its obligations under the Leases to which
        such Lessor is a party.

               C. At the request of TBC, each of the Lessors has agreed to the
        termination of the Guarantys, provided that TBC agrees to be joined to
        the Leases as a lessee thereunder.

        NOW, THEREFORE, in consideration of the termination of the Guarantys,
TBC hereby agrees as follows:

        1. TBC shall be, and by its execution of this Agreement, TBC is hereby,
joined to each of the Leases as a Tenant, as defined in each of the Leases,
effective as of the Effective Date.

        2. TBC shall be fully liable, jointly and severally, with NTW for all of
the Tenant's obligations under each of the Leases to the same extent as if TBC
had been originally named therein as a Tenant.

        3. TBC's obligations as a Tenant under each of the Leases shall not be
affected by any failure of NTW to perform any of its obligations under any
Lease, regardless of the reason for such nonperformance.


<PAGE>



        TBC HEREBY RATIFIES, CONFIRMS, AND APPROVES all of the terms and
provisions of each of the Leases, as executed by NTW and the Lessor named
therein, and acknowledges that the Leases are in full force and effect and
binding upon NTW and TBC in accordance with their respective terms.

        IN WITNESS WHEREOF, TBC has executed this Joinder Agreement effective as
of the Effective Date.
