EXHIBIT 10.13 Cyberian Outpost, Inc. has omitted from this Exhibit 10.13 portions of the Agreement for which Cyberian Outpost, Inc. has requested confidential treatment from the Securities and Exchange Commission. The portions of the Agreement for which confidential treatment has been requested are marked with X's in brackets and such confidential portions have been filed separately with the Securities and Exchange Commission. PROMOTION AGREEMENT This Promotion Agreement (the "Agreement") is dated as of January 26, 1998 between CNET, Inc. ("CNET") and Cyberian Outpost, Inc. (the "Company"). Pursuant to this Agreement, CNET will provide various links and other online and television promotions (collectively, the "Promotions") to the Company to assist the Company in promoting its products and services and facilitating the sale of products to potential buyers through its Internet site. CNET will be compensated by the Company for providing the Promotions. Accordingly, the parties hereby agree as follows: 1. Background. 1.1 The Company. The Company operates an electronic retailing operation through its Internet sites located at www.cyberianoutpost.com or www.outpost.com (together with any successors to such sites, the "Company Site"). Through the Company Site, the Company sells or facilitates the sale of various products and services, either directly or as an agent for third party vendors. All products and services offered for sale through the Company Site are referred to as the "Products." 1.2 CNET. CNET produces television programs and operates a network of Internet sites on the world wide web. For purposes of this Agreement, the "CNET Sites" refer to any Internet sites operated by CNET or its subsidiaries, including without limitation the sites referenced in Section 2.5 and Exhibit A. 2. CNET's Obligations. 2.1 TV Promotions. CNET will provide the Company one 15 second "spot" for Promotions on its syndicated weekly TV program, TV.COM. Promotions will run on each weekly episode of TV.COM during the Term; provided that TV.COM remains on the air throughout such period. Should TV.COM not be run on the air during a portion of the Term, CNET will run two download.com banner advertising programs per month during such portion of the Term in lieu of the foregoing TV.COM Promotions. 2.2 Banner Promotions. CNET will provide advertising banners to the Company during the Term as described in Exhibit A. 2.3 Retail Promotions. 2.3.1 CNET will provide for various retail Promotions across the CNET Sites, which may include text/HTML links, buttons, portals and other fixed Promotions that include embedded links to the Company Site (the "Retail Promotions" and, together with the advertising banners contemplated in the preceding paragraph, the "Online Promotions"). 2.3.2 Subject to Section 4 below, CNET will provide the Company with a total of at least (a) [XXXXXX] Retail Impressions during the first three months of the Term, (b) [XXXXXX] Retail Impressions during the second three months of the Term, (c) [XXXXXX] Retail Impressions during the third three months of the Term, and (d) [XXXXXX] Retail Impressions during the fourth three months of the Term. For such purposes, a "Retail Impression" means the display of one page of a CNET Site that contains at least one Retail Promotion. If CNET fails to provide the Retail Impressions required by the preceding sentence during the Term, then CNET will continue to display Retail Impressions in accordance with this Agreement following the Term (notwithstanding the termination or expiration of the Term) until the required number of Retail Impressions has been delivered. 2.4 Placement of Retail Promotions. CNET will determine the location and type of each Retail Promotion displayed throughout the CNET Sites and may phase in certain types of Retail Promotions as they are developed. CNET currently intends to display Retail Promotions consisting of text/HTML links, pre-filled with an appropriate query string or link ("Pre-Filled Links"), as set forth in this Section. The Retail Promotions contemplated by this Section will be displayed above the fold where the graphical layout of the page reasonably permits such positioning (as determined by CNET), and in other cases the Retail Promotions will be prominently positioned below the fold.
