the URL if appropriate and necessary: "On Line Merchandise offerings may vary
from products offered in The Sports Authority stores."

Upon receipt of such request, TSA.com shall provide the Customer Data or

diskette, CD-ROM, electronically, or via another mutually agreeable method.

the other Party. For the purpose of this Agreement, "Confidential Information"
shall mean information or materials that is marked "confidential" or which the
Receiving Party knows or has reason to know is the confidential or proprietary
information of the Disclosing Party, either because (i) such information is
marked or otherwise identified by the Disclosing Party as confidential or
proprietary, or (ii) 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

     ---------------
maintain in strict confidence all Confidential Information of the Disclosing
Party and, except as otherwise permitted herein, not to disclose it to any third

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 11
shall terminate five (5) years after the expiration or termination of this
Agreement.

Confidential Information shall not include any information that: (a) was in 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 in the E-Commerce
Services Agreement by and among TSA.com, GSI and Retailer of even date herewith.

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

applicable period has expired after a Second Request and the Party receiving the
second submission has failed to reply.

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,

Compliant that: (i) affects the non-performing party's customers or suppliers;
or (ii) is beyond its reasonable control.

     --------
and hold harmless TSA.com and any of its officers, directors, employees or

Marks as permitted hereunder and under the License Agreement, including use of
Retailer's URL and of the name and Mark "TheSportsAuthority.com" infringes the
trademark, service mark, trade dress or trade name rights of any third party in
the U.S., its territories and possessions, Puerto Rico, or Canada, provided,
however, that Retailer shall not bear any duty, obligation or liability pursuant
to this Article 15.1 to the extent that, and with respect to which, any use by

related in any way to the TSA Site, the E-Commerce Business, On-Line Merchandise

negligence or willful or intentional misconduct.

15.3 Any Party seeking indemnification shall notify the other Party as soon as
possible after such Party seeking indemnification becomes aware of the claim.
Except with respect to infringement claims asserted under 15.1(a) which Retailer
shall have the sole right to defend, the indemnifying Party shall have the right
to defend any claim pursuant to this Article XV.  The indemnified Party 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 the indemnifying
Party.

                          ASSET SUBMISSION GUIDELINES

This section details how to submit assets.

Source Assets and Final Assets
------------------------------

We require source files for all assets. This means if an image is originally
   constructed as a layered RGB Photoshop file at 100x500 pixels, we need that
   file, even if the final file is a flattened 4-bit GIF at 20x100.

We allow the submission of final assets in some cases, but only by prior
   arrangement and only in addition to an up-to-date source file. All submitted
   assets are subject to review and verification by production staff.

Media and Format
----------------

We routinely receive assets in the following media and formats:

Digital Media:
   Media:
   SyQuest 44mb, 88mb, 200mb, CD-ROM (including PhotoCD), Zip, Jaz, 3.5"
floppy.

   Format:
   Win16, Win-32, or Macintosh

   File Formats:
   Text: Raw, MS Word 95, RTF, HTML

   Bitmap Graphics:
   Photoshop, TIFF, PCD (PhotoCD), EPS, PICT (JPEG and GIF for final files only
and only along with source files)

   PostScript Graphics:
   EPS, Illustrator (7.0 preferred)

<PAGE>

Non-Digital Media:
Contact us to discuss needs and capabilities before submitting any non-digital
assets.

Asset Submission
----------------

We prefer to receive assets via FTP (file transfer protocol) although we gladly
   accept assets via standard package delivery services (i.e., FedEx, USPS, UPS,
   etc.).

Submission via FTP

FTP Area: ftp.globalsportsinteractive.com

Assets should be left in "Incoming" which is a level below the initial
   directory. Once assets have been transferred, e-mail confirmation is
   required.

Submission via Package Delivery

If you wish to submit assets via standard package delivery services, please
   address the package to this address:

Address TBD

If you are submitting hard assets like brochures, photographs, etc. please be
   sure to ship them in a reinforced container to prevent damage to the assets
   while in transit.

If you are submitting digital media like SyQuests, Zip disks, Jaz disks, etc.,
   be sure to ship them in a well-padded, reinforced container.
