this Section 4.7, provided that such sales and/or redemptions by Licensee do not
subject it to nexus with any state for sales tax purposes. In the event that

subject it, or may subject it, to nexus with any state for sales tax purposes,
then Licensee shall provide Licensor notice of such determination and each
Party's obligations pursuant to this Section 4.7, other than each Party's

Order for a Universal Gift Card, Licensee will promptly contact the Universal
Gift Card account administrator (the "Gift Card Administrator") for the purpose
of providing the purchase information necessary to update the Universal Gift
Card account database.

          (c)   Subject to the terms and conditions herein, Licensee will accept
payment through Universal Gift Cards for the sale of Merchandise through the
TSA.com Site. Licensor will authorize the Gift Card Administrator to permit
Licensee to directly access, through a secure connection, the Universal Gift
Card database to permit Licensee, on a real-time basis, to validate balances for
Universal Gift Cards.

          (d)   Within thirty (30) days after the end of each quarter of
Licensee's fiscal year, Licensor and Licensee shall each provide to the other
the information necessary to determine the payments set forth below. Within
forty-five (45) days after the end of each quarter of Licensee's Fiscal Year,
Licensor or Licensee, as the case may be, shall owe the other Party the net
amount determined by adding 4.7(d)(i) and 4.7(d)(ii) below:

     redeemed during the applicable quarter [*].

                    (iii)   For purposes of this Section 4.7(d), "Licensee

with (i) all required technical specifications to permit Licensee to submit and
receive data concerning Universal Gift Cards, (ii) reports which are necessary
or desirable to permit Licensee to review, track and reconcile all applicable
Universal Gift Card transactions, and (iii) such other reasonably requested
information and reports concerning the Universal Gift Cards.

     1.6  Section 9 of the Agreement is hereby amended by inserting in the first
sentence thereof after "TSA Stores" the words "or at such other locations
selected by Licensor" and by deleting the words "at such TSA Stores" from the
second sentence thereof.

     1.7  Exhibit J1 of the Agreement is hereby amended by deleting the "1/4"
Inside Footers" heading of the last column of the first table (Circular:
Integration Space Requirements) and replacing it with the heading "1/2" Inside

full force and effect in accordance with its terms.

agreement.
