"There are tremendous synergies with these two companies that will allow SportsLine.com to realize a guaranteed revenue stream, while reducing costs and enhancing the offerings to our users in the fantasy, contests and sports games area," said Michael Levy, founder and CEO of SportsLine.com, Inc. "We recognize the importance of the fantasy sports audience in terms of page views and stickiness: the length of time they spend on our site, the amount of research and statistics that fantasy players utilize, and their aptitude for purchasing sports merchandise and memorabilia."

The Company's acquisition of DWWC, ensures SportsLine.com its continued leadership position in the fantasy sports arena, without continuing to share subscriber and advertising revenues.

The consideration for the acquisition of DWWC is $31 million, consisting of approximately $27 million of SportsLine.com common stock, and $4 million in cash. SportsLine.com also agreed to issue additional common stock, if certain revenue and/or subscription targets are reached. DWWC will be operated as Commissioner.COM, Inc., a subsidiary of SportsLine.com, with the operations remaining in New York City.

Under the terms of its four-year agreement with ISN, SportsLine.com will receive a minority equity stake that could grow up to 19.9%, with warrants and other securities, two Board positions and $17 million in cash as a guarantee against advertising and subscription revenue sold by SportsLine.com, in exchange for promotion and distribution of ISN's array of products. ISN currently has more than 1.7 million registered users and creates and manages private label contests for some of the world's most trafficked Web sites.

The addition of ISN's fantasy products to SportsLine's Commissioner.COM offerings will provide more selections for the fantasy player, which will result in more activity and additional ways for advertisers to reach this devoted and passionate audience.
