MOUNTAIN VIEW, Calif., Sept.23, 1997 -- ONSALE, Inc., (NASDAQ:ONSL) a pioneer and leader in interactive 24-hour online auctions, and CBS SportsLine, a leading Internet-based sports media service published by SportsLine USA, Inc., today announced a broad joint commerce partnership. As part of the agreement, ONSALE will launch a co-branded Sports & Fitness Auction SuperSite where CBS SportsLine will showcase merchandise using ONSALE's state-of-the-art auction management system. ONSALE is guaranteed a continuing supply of sports memorabilia and sports-related products to sell.

"Our studies have shown that our customer base has a keen interest in sports," said Jerry Kaplan, CEO and Co-Founder of ONSALE. "It appears that the action-oriented, dynamic character of the typical sports enthusiast transfers well to the competitive bidding environment of an online auction. Furthermore, our joint auction market tests of sports-related merchandise with CBS SportsLine were highly successful."

"Auctions of sports-related merchandise are a natural for our audience. Partnering with a leading company in this space accelerates our own merchandise sales efforts and adds to the entertainment value of our offering," added Andrew Sturner, Vice President, Business Development for SportsLine USA, Inc.

Under the agreement, extensive links will appear on each company's web sites to drive traffic to the other partner. This arrangement is characteristic of the changing distribution economics of the web, where key market leaders are leveraging their brand identities to acquire permanent "real-estate" on high-affinity sites. This agreement also illustrates how ONSALE can gain access through partnerships to expanded categories of merchandise and sources of supply.

How ONSALE Works
Buying at ONSALE is easy and fun. To place a bid, customers click a button on their computer screen and fill out a simple registration form. Typically, a number of identical items are auctioned off simultaneously. When bids are received, prices change or merchandise is sold, ONSALE's Web pages are automatically updated with the latest inventory and/or pricing information. If a customer's bid is no longer the highest, they can increase their bid directly from ONSALE's Web site or via electronic mail. When the auction closes, winning customers are notified via electronic mail and listed on the Web site.
