reasonable actual direct costs (without markup) ("GSI's Direct Costs") of
creating and operating the TSA Site and TSA.com's pro rata share of GSI's
commercially reasonable actual indirect costs (without markup)("GSI's Indirect

allocation of GSI including rent, taxes (other than income taxes) and utilities,
GSI management personnel allocation, capital expenditures, including hardware
and software costs, common engine allocation and hosting allocation. GSI shall
not allocate or charge to TSA.com any sums as either GSI's Direct Costs or GSI's

performed or paid by GSI on behalf of TSA.com or Retailer as otherwise provided
in the E-Commerce Agreement.

2.3  TSA.com's Payments.  GSI's Entitlement shall be calculated and charged by

                                  ARTICLE III
                  CUSTOMER DATA, FINANCIAL DATA AND DATABASES

3.1  Ownership and Use of Customer Data.  [*] shall own all right, title and
     ----------------------------------
interest in and to the Customer Data, while [*].   GSI shall adhere to all
United States privacy and data protection laws applicable to its gathering,
processing, storing and transmitting of Customer Data.  GSI shall use its best
efforts to adhere to all such privacy and data protection laws of all other
nations and shall indemnify TSA for any loss, damage or expense caused by its
failure to do so; provided, however, that the parties agree that such failure to
do so shall not be deemed a breach of this Agreement.

3.2  Confidentiality of the Customer Data.  Under the E-Commerce Agreement, both
     ------------------------------------
Retailer and TSA.com have agreed that each Party shall treat the Customer Data
as Confidential Information of the other Party, that TSA.com may use Customer
Data in the operation of the TSA Site and the E-Commerce Business, and that
Retailer may use the Customer Data in the operation of Retailer's land based
stores, but that neither Retailer nor TSA.com shall furnish, rent, sell or
otherwise disclose Customer Data to any person or entity whatsoever without the
prior written consent of the other Party.  Further, under the E-Commerce
Agreement, both Retailer and TSA.com have agreed not to furnish, rent, sell or
otherwise disclose to any person or entity whatsoever any Financial Data,
without the other Party's prior written consent and subject to such terms and
conditions as the Parties may mutually determine. Notwithstanding the foregoing,
Retailer and TSA.com have agreed that TSA.com may permit GSI, at no charge to
GSI, to use Financial Data (but not Customer Data) to form trends and overall
research as to the on-line shopping habits of consumers. GSI agrees to treat the
Customer Data as Confidential Information and shall not furnish, rent, sell or
otherwise disclose Customer Data to any person or entity whatsoever without the
prior written consent of Retailer.

                                CONFIDENTIALITY

4.1  Confidential Information.  Each Party acknowledges that, in connection with
     ------------------------
the performance of this Agreement, it may receive Confidential Information of
the other Party and that GSI may receive Confidential Information of Retailer
(which shall be deemed a "Disclosing Party for purposes of this Agreement).  For
the purpose of this Agreement, "Confidential Information" shall mean information
or materials that is marked "confidential" or which the Receiving Party knows
has reason to know is the confidential or proprietary information of the
Disclosing Party, either because a) such information is marked or otherwise
identified by the Disclosing Party as confidential or proprietary, or b) such
information has commercial value and is not generally known in the Disclosing
Party's trade or industry.  Confidential Information shall include, without
limitation:  (a) concepts and ideas relating to the development and distribution
of content in any medium; (b) trade secrets, drawings, inventions, know-how,
software programs, and software source documents; (c) information regarding
plans for research, development, new service offerings or products, marketing
and selling, business plans, business forecasts, budgets and unpublished
financial statements, licenses and distribution arrangements, prices and costs,
suppliers and customers; (d) existence of any business discussions, negotiations
or agreements between the parties; (e) the terms and conditions of this
Agreement; (f) all information with respect to Retailer's vendors, Retailer's
price and cost structures, TSA.com's vendors, TSA.com's merchandise price and
cost structures, the cost of merchandise sold by TSA.com, the existence or
amount of any cooperative advertising subsidy or rebate; and (g) all prices of
merchandise to be sold on the TSA Site prior to publication of such prices on
the TSA Site; provided, however, that Retailer shall be provided with the
information referred to in clauses (f) and (g).

4.2  Confidentiality.  The Receiving Party hereby agrees: (i) to hold and
     ---------------
maintain in strict confidence all Confidential Information of the Disclosing
Party and, except as otherwise permitted herein, not to disclose it to any third
party; and (ii) not to use any Confidential Information of the Disclosing Party
except as permitted by this Agreement or as may be necessary for the Receiving
Party to perform its obligations under this Agreement.  The Receiving Party
shall use at least the same degree of care to protect the Disclosing Party's
Confidential Information as it uses to protect its own Confidential Information
of like importance, and in no event shall such degree of care be less than
reasonable care.  The obligations and restrictions imposed by this Article IV
shall terminate five (5) years after the expiration or termination of this
Agreement.

4.3  Exceptions.  Notwithstanding the foregoing, the parties agree that
     ----------
Confidential Information shall not include any information that:  (i) was in the
public domain at the time it was communicated to the Receiving Party by the
Disclosing Party; (ii) entered the public domain subsequent to the time it was
communicated to the Recipient by the Disclosing Party through no

                                       3
<PAGE>

fault of the Receiving Party; (iii) was in the Receiving Party's possession free
of any obligation of confidence at the time it was communicated to the Receiving
Party by the Disclosing Party; (iv) was rightfully communicated to the Receiving
Party by a third party, free of any obligation of confidence, subsequent to the
time it was communicated to the Receiving Party by the Disclosing Party; (v) was
developed by employees or agents of the Receiving Party independently of and
without reference to any information communicated to the Receiving Party by the
Disclosing Party; or (vi) was communicated by the Disclosing Party to an
unaffiliated third party free of any obligation of confidence. In addition, the
Receiving Party may disclose the Disclosing Party's Confidential Information in
response to a valid order by a court or other governmental body, as otherwise
required by law, or as necessary to establish the rights of either party under
this Agreement; provided, however, in the event that the Receiving Party
receives a demand to disclose such Confidential Information in connection with a
legal action or proceeding, the Receiving Party, if possible, shall first notify
the Disclosing Party of the demand in order to provide the Disclosing Party an
opportunity to seek a protective order. TSA.com may also disclose certain of
Retailer's Confidential Information to GSI in connection with the performance by
GSI of its duties, but only to the extent expressly permitted herein.

4.4  Confidentiality of this Agreement.  The Parties acknowledge that the terms
     ---------------------------------
and conditions of this Agreement constitute Confidential Information which shall
be governed by the terms of this Article 4.

                                   ARTICLE V
                                   APPROVALS

5.1  Approval Process.  Except as otherwise expressly set forth in the E-
     ----------------
Commerce Agreement and herein, and except with respect to any use of "Licensed
Property" (as defined in the License Agreement) which requires approval under
the License Agreement, when a given provision calls for prior review and
approval by one Party of a submission by the other Party, the Party receiving
the submission shall review it in a timely manner and use its best efforts to
communicate in writing its approval or disapproval as soon as practicable after
receiving the same. Failure to communicate approval within five (5) Business
Days of receipt of the submission shall be deemed a disapproval. The submitting
Party may re-start the approval process by making a second submission marked
"Second Request." The Party receiving the second submission shall again review
it in a timely manner and use its best efforts to communicate in writing its
approval or disapproval as soon as practicable after receiving the same. Failure
to communicate approval within five (5) Business Days of receipt of the
submission shall be deemed an approval. In no event, shall the Party seeking
approval produce, distribute, or otherwise follow through on or implement the
subject of the submission until approval is granted in writing by the Party
charged with the right of approval, or until the applicable period has expired
after a Second Request and the Party receiving the second submission has failed
to reply.

                                   ARTICLE VI
                         REPRESENTATIONS AND WARRANTIES

                                       4
<PAGE>

6.1  Both Parties.  Each Party represents and warrants to the other Party that:
     ------------
(i) it is a corporation duly organized, validly existing and in good standing
under the laws of its state of incorporation and that it has the power and
authority to enter into this Agreement and the transactions contemplated herein;
(ii) the consummation of the transactions described by this Agreement shall not
conflict with or result in a breach of any of the terms, provisions or
conditions of its Articles of Incorporation or Bylaws, or any statute or
administrative regulation or any order, writ, injunction, judgment or decree of
any court, regulatory or governmental authority or of any agreement or
instrument to which it is a party or by which it is bound or constitute a
default thereunder; and (iii) this Agreement has been duly authorized, executed
and delivered by it and this Agreement is valid, enforceable and binding upon
each Party in accordance with its terms.

6.2  Year 2000.  GSI warrants to TSA.com and Retailer that the TSA Site shall
     ---------
not suffer any material adverse effect as a result of a failure in any TSA.com
Work Product or TSA.com Tools to be Y2K Compliant.  A product or service which
is "Y2K Compliant" is one that provides accurate results using data having date
ranges spanning from January 1, 1980 through December 31, 2019 ("Y2K Period").
By way of example and not of limitation, "Y2K Compliant" means, with respect to
a product or service, that it can currently and shall, during the Y2K Period,
continue to (a) manage and manipulate data involving all dates within the Y2K
Period (including the fact that the year 2000 is a leap year) without functional
or data abnormality related to such dates; (b) manage and manipulate data
involving all dates within the Y2K Period without inaccurate results related to
such dates; (c) have user interfaces and data fields formatted to distinguish
between dates within the Y2K Period; and (d) accurately identify and either
reject or correct invalid date data during the Y2K Period.  Provided TSA.com
otherwise complies with this Article 14.2, it shall not be liable to Retailer
for any failure to perform obligations under this Agreement to the extent such
failure arises from a failure to be Y2K Compliant that: (i) affects the non-
performing party's customers or suppliers; or (ii) is beyond its reasonable
control.

                                  ARTICLE VII
                                INDEMNIFICATION

7.1  GSI, at its own cost and expense, shall defend, indemnify and hold harmless
TSA.com and Retailer and any of their officers, directors, employees or agents
from and against all damages, expenses, liabilities and other costs (including
reasonable attorneys' fees and court costs) arising:  (a) from a claim made by
any party (other than TSA.com or Retailer) that is related in any way to
services furnished by GSI with respect to the TSA Site or GSI's services to
TSA.com or Retailer provided pursuant to this Agreement; or (b) from GSI's gross
negligence, willful or intentional misconduct.  TSA.com or Retailer shall notify
GSI as soon as possible after TSA.com becomes aware of a claim.  GSI shall have
the sole right to defend any claim pursuant to this Article VII.  TSA.com and
Retailer shall cooperate with such defense and, at its option, may also defend
such claim to the extent that its interests in any way vary from that of GSI.

                                  ARTICLE VIII
                                   INSURANCE

     (b) Workers' Compensation and Employers' Liability with minimum limits of

                                   ARTICLE IX
                              TERM AND TERMINATION

9.1  This Agreement shall commence on the Effective Date and automatically
terminate upon termination of the E-Commerce Agreement, or terminate pursuant to
Article 9.1(a) or (b) below:

     (a) By either party if the other party shall materially default in the
performance of any of the covenants, terms and conditions of this Agreement and
shall fail to cure such default within 60 days after receipt of notice in
writing from the terminating party of such default, giving reasonable
particulars of such default and of the intention of the party serving the notice

the same within such period.
