                      ADVERTISING AND PROMOTION AGREEMENT

     This Amendment #1 (this "Amendment") is entered into as of February 15,
2000 (the "Amendment Effective Date") by and between Yahoo! Inc., a Delaware
corporation ("Yahoo") and Global Sports Interactive, Inc., a Pennsylvania
Corporation ("Global Sports") and amends the Advertising and Promotion Agreement

"Agreement").  Unless otherwise expressly defined herein, all capitalized terms
and Section references used herein shall have the meanings set forth in the
Agreement.

     WHEREAS, as of the Amendment Effective Date, Yahoo and Global Sports desire
to limit Global Sports' exclusivity rights under Section 11 of the Agreement;

     WHEREAS, as of April 1, 2000, Yahoo and Global Sports desire to terminate
Yahoo's obligation to promote the Global Sports Links under Sections 2, 3, 4.2,
5, 6, 7 and 8 of the Agreement;

     WHEREAS, as of April 1, 2000, Yahoo and Global Sports desire that Yahoo

     WHEREAS, as of the Amendment Effective Date, Yahoo and Global Sports desire
that Yahoo display the Global Sports Banner as set forth below and in Yahoo

Agreement as follows:

1.   In Section 1 of the Agreement, the definition of the word "Term" shall be
replaced by the following definition and the word "Amendment Effective Date"
shall have the following meaning:

     "Term" shall mean the period beginning on the Effective Date and continuing

2.   In Section 1 of the Agreement, the following definition shall be added:

     "Global Sports Sports & Recreation Shopping Links" shall mean all of the
      ------------------------------------------------
     Paid Advertising provided in the Sports and Recreation category Pages of
     Yahoo Shopping (including the Global Sports Charter Shopping
     Sponsorship) with the following exceptions: (i) only [*] of the Paid
     Advertising in the Yahoo Shopping Outdoor area; (ii) only [*] of the Paid
     Advertising in the Yahoo Shopping Golf area; (iii) only [*] of the Paid
     Advertising in the Yahoo Shopping Sports Supplements area; (iv) only
     [*] of the Paid Advertising in the Yahoo Shopping Sports Memorabilia area.

3.   In Section 1 of the Agreement, the definition of the word "Page View" shall
     be replaced in its entirety by the following definition:

     "Page View" shall mean a user's request for a Page as measured by Yahoo's
     advertising reporting system.  Global Sports acknowledges and agrees that
     multiple Global Sports Links on the same Page requested by a user (e.g.,
     Sports and Recreation category Pages of Yahoo Shopping) could result in
     multiple Page Views being generated; provided that, Yahoo agrees that
     multiple Page Views will not be counted for multiple Global Sports Links
     appearing on Global Sports Banner Pages and Global Sports Button Pages.

4.   Section 9 of the Agreement shall be replaced in its entirety with the
     following:

     Between the Effective Date and March 31, 2000, Yahoo will deliver [*]
     Global Sports E-Mails through the Yahoo! Delivers program.  In all cases,
     Global Sports E-Mails shall be delivered only (x) to those registered users
     of Yahoo's U.S. targeted e-mail service that have indicated during the
     registration process for such service a willingness to receive promotional
     solicitations via Yahoo Mail; and (y) in accordance with Yahoo's privacy
     policy.  The text of the Global Sports E-Mail shall be provided by Global
     Sports, consistent with Yahoo's standard policies and guidelines for such
     messages as set forth in Exhibit O, and shall be subject to Yahoo's prior
                              ---------
     approval (which shall not be unreasonably withheld).  Yahoo will provide
     Global Sports with three agreed-upon attributes (e.g., age, gender,
     occupation) that may be used to target to registered users who receive the
     Global Sports E-Mails.

5.   Section 11 of the Agreement shall be replaced in its entirety with the
     following:

     11.1 Beginning on the Amendment Effective Date and continuing until
     December 31, 2000, Yahoo shall not [*].  The parties acknowledge and agree
     that, other than expressly set forth in this Section 11.1, Yahoo shall not
     be restricted in any manner from promoting any entity (including, but not

     limited to, Mammoth Golf and professional sports leagues) on the Yahoo
     Properties.

     11.2  Global Sports acknowledges that Yahoo has existing contractual
     obligations with the merchants set forth on Exhibit H ("Existing
                                                 ---------
     Obligations") and that notwithstanding anything to the contrary in this
     Agreement, Yahoo shall be permitted to fulfill the Existing Obligations
     without being considered to be in breach of its obligations under this
     Agreement.   Further, under no circumstances shall anything in this Section
     11 be deemed to restrict in any manner Yahoo's ability to (i) integrate any
     editorial content (other than branded content that may be provided by
     Global Sports Competitors) in any Yahoo Property, or (ii) include links to
     any entity in any directory, merchant listing or other shopping service or
     feature on any Yahoo Property.  To the extent that it is not contractually
     obligated to do so, Yahoo agrees that it will not, in a manner inconsistent
     with Yahoo's obligations under Section 11, (x) extend or renew an Existing
     Obligation, or (y) consent to the extension or renewal of an Existing
     Obligation if Yahoo may withhold such consent in its sole discretion.

6.   Effective April 1, 2000, Section 12 of the Agreement shall be deleted (and
     all obligations therein shall be deemed fulfilled) and replaced in its
     entirety with the following:

     12.1  Beginning on April 1, 2000 and continuing through December 31, 2000,
     Yahoo shall provide Global Sports the Global Sports Sports & Recreation
     Shopping Links.  Yahoo shall guarantee delivery of [*] Page Views of the
     Global Sports Sports & Recreation Shopping Links.

     12.2  Between April 1, 2000, and December 31, 2000, Yahoo shall provide the
     Global Sports Banner on a rotating basis on the Global Sports Banner Pages.
     Yahoo shall guarantee delivery of [*] Page Views of such Global Sports
     Banner. For purposes of this Section 12.2, Global Sports Banner Pages shall
     mean: (i) those Pages displayed upon a user's searching the Yahoo Main Site
     for a keyword set forth on Exhibit 1 to Amendment #1 to this Agreement,
     dated as of February 15, 2000 ("Amendment #1"); and (ii) those Pages within
     the Yahoo Main Site categories set forth on Exhibit 1 to Amendment #1.

     12.3  In the event that Yahoo fails to deliver the minimum number of Page
     Views as set forth above at the expiration of the Term, Yahoo will "make
     good" the shortfall [*] after the end of the Term until such Page View
     obligation is satisfied. If Yahoo is unable to fulfill its Page View
     obligations through the original promotion during this additional period,
     Yahoo will then have an additional [*] to deliver the required number of
     Page Views through a comparable promotion acceptable to Global Sports (such
     three month period, together with the six month period described in the
     preceding sentence, being referred to collectively as the "Make Good
     Period"). The provisions set forth in this Section 12.3 set forth the
     entire liability of Yahoo, and Global Sports' sole remedy, for Yahoo's
     breach of its Page View obligations set forth in Sections 12.1 and 12.2
     during the Term. For clarity, the parties acknowledge that the exclusivity
     provisions of Section 11 shall not extend beyond the Term and that the sole
     remedy set forth above shall not apply to a failure by Yahoo to fulfill its
     Page View obligations during the Make Good Period.

     1.4  During the Term, Yahoo will provide Global Sports access to an
     electronic database that tracks the delivery of Page Views under this
     Agreement. Such database will be updated in accordance with Yahoo's
     standard updating procedures at least once per Quarter.

7.   Sections 13.1, 13.2, 13.3, 13.4, and 13.5 of the Agreement shall be deleted
     (and all obligations therein shall be deemed fulfilled) and replaced in
     their entirety with the following. The parties expressly acknowledge and
     agree that Global Sports' obligation to deliver the Barter Media pursuant
     to Section 13.9 of the Agreement shall remain in full force and effect.

     1.1  Within five (5) business days of the Amendment Effective Date, Yahoo
     shall [*] to Global Sports [*] of the Slotting Fee.

     1.2  In consideration of Yahoo's performance and obligations as set forth
     herein under Section 5 of Amendment #1, Global Sports will compensate Yahoo
     in an amount equal to [*]. Such fee shall be due and paid to Yahoo as
     follows: (i) [*] on April 1, 2000; (ii) [*] on May 1, 2000; (iii) [*] on
     June 1, 2000; (iv) [*] on July 1, 2000; (v) [*] on August 1, 2000; (vi)
     [*]on September 1, 2000; (vii) [*] on October 1, 2000; (viii) [*] on
     November 1, 2000; (ix) [*] on December 1, 2000.

     1.3  Revenue Share.  In addition to the fees set forth in Section 13.2
          -------------
above, Global Sports shall pay to Yahoo a non-refundable, non-creditable fee
equal to [*] percent ([*]%) of any Global Sports Revenue earned beginning on
April 1, 2000, and continuing through the remainder of the Term (the "Revenue
Share Fee"). Yahoo acknowledges and agrees that all revenue share fees in
connection with Global Sports Revenue earned prior to April 1, 2000 shall be
deemed fulfilled. In accordance with the definition of Global Sports Revenue, it
is understood that Global Sports Revenue does not include revenue from sales
made through the Global Sports Site (as opposed to the Merchant Pages, which are
displayed by Yahoo through a proxy server). The Revenue Share Fee shall be paid
by Global Sports to Yahoo on a quarterly basis within the later of (i) thirty
(30) days following the last day of each calendar quarter of the Term, and (ii)
ten (10) days following Global Sports' receipt of a Yahoo's written invoice
calculating: (i) the total dollar amount of Global Sports Revenue earned during
the applicable period, and (ii) a calculation of the Revenue Share Fee.

8.   Effective April 1, 2000, Yahoo's obligations to promote the Global Sports
     Links under Sections 2, 3, 4.2, 5, 6, 7 and 8 of the Agreement shall cease
     and all obligations therein and relating thereto shall be deemed fulfilled.

9.   Section 14.4(a) of the Agreement shall be deleted and Global Sports shall
     have no right to terminate the Agreement (as amended by this Amendment)
     pursuant to such Section. The references to Section 14.4(a) shall be
     deleted from Sections 13.9 and 14.6.

10.  Section 14.5 of the Agreement shall be deleted and Global Sports shall have
     no right of first presentation pursuant to such Section.

     ---------                                                       ---------
     attached hereto

12.  Global Sports acknowledges and agrees that during the Term, the Global
     Sports Retailers shall continue to participate in Yahoo's Remote Merchant
     Integration program in accordance with the terms of the Remote Merchant
     Integration Program Agreement.

13.  In accordance with Yahoo Insertion Order No. 72687, Yahoo shall deliver a
     minimum of [*] Page Views of the Global Sports Banner. Yahoo will deliver
     such Page Views as follows: (i) at least [*] Page Views between the
     Amendment Effective Date and March 31, 2000; and (ii) any remaining Page
     Views by June 30, 2000. No less than [*] of such Page Views shall be
     delivered in banner positions rotating throughout the Yahoo Main Site, with
     the remainder being delivered in banner positions rotating throughout the
     Yahoo Properties.

14.  Except as expressly amended as set forth herein, the Agreement shall remain
     in full force and effect in accordance with its terms.

                    FIRST AMENDMENT TO E-COMMERCE AGREEMENT
                    ---------------------------------------

     This FIRST AMENDMENT TO E-COMMERCE AGREEMENT made the 17th day of June,
1999 by and between GLOBAL SPORTS INTERACTIVE, INC., a Pennsylvania corporation
("GSI") and MICHIGAN SPORTING GOODS DISTRIBUTORS, INC., a Michigan corporation
("Retailer").

                             W I T N E S S E T H:

     WHEREAS, on February 1, 1999, GSI and Retailer entered into an E-Commerce
Agreement ("Agreement") pursuant to which GSI agreed to act as the outsourcing
company providing the Retailer's on-line customers the complete e-commerce
shopping experience; and

     WHEREAS, GSI and Retailer desire to amend the Agreement, all as hereinafter
set forth.

     NOW, THEREFORE, the parties hereto, intending to be legally bound hereby,
agree as follows:

1.   The Agreement is amended to add the following paragraph 32:

           Upon execution of this First Amendment by Retailer, and
           acceptance thereof by GSI, prior to the announcement of
           GSI's e-commerce initiative, GSI will deliver to Retailer
           a Warrant to Purchase Shares of Global Sports, Inc., the
           parent corporation of GSI, in accordance with the terms
           set forth in the Warrant Term Sheet attached hereto as
           Exhibit "B".

2.   Retailer acknowledges that it is aware that GSI is negotiating with The
     Sports Authority, Inc. ("TSA") pursuant to which GSI and TSA will form a
     separate joint venture to operate TSA's on-line business. Retailer
     acknowledges that the joint venture between GSI and TSA is not the type of
     agreement which would entitle Retailer to invoke the "favored nations"
     clause contained in the first sentence of Section 3.8 of the Agreement, and
     Retailer consents to GSI entering into such joint venture with TSA.

3.   In all other respects, the Agreement shall remain in full force and affect
     and unamended.
