Sibling's Affiliate M-1 Global Announces Fedor's First Fight and A Broadcast Agreement With HDNet

NEW YORK, Dec. 10 /PRNewswire-FirstCall/ -- Sibling Entertainment Group Holdings, Inc. (OTC Bulletin Board: SIBE( ["Sibling Holdings"] announced that last week in Tokyo an affiliate of Sibling Entertainment Group, Inc.(1), M-1 Global, LLC ["M-1 Global"](2) made good on its promise to cooperate with other mixed martial arts organizations.

M-1 Global will support the organizers for the Yarennoka! New Year's Eve event in Japan which will feature M-1 Global superstar Fedor Emelianenko in their main event at the 22,000-seat Saitama Super Arena. It was previously announced in October that M-1 Global had signed Fedor who is widely considered the best MMA fighter in the world, and who owns a 26-1 record.

Participation in the Yarennoka event will allow M-1 Global and Sibling Sports LLC to launch its MMA operation in 2007, several months in advance of its first major U.S. event planned for early 2008.

In addition, M-1 Global announced an agreement signed with HDNet Fights for HDNet to broadcast LIVE from Japan the entire Yarennoka New Year's Eve event featuring Fedor Emelianenko. "HDNet Fights: Fedor Returns" will air LIVE on Monday, December 31 on HDNet.

Mitchell Maxwell, Chairman and CEO of Sibling Entertainment Group Holdings, Inc. (and Sibling Holdings), stated, "This is a major step, but only the beginning for M-1 Global and Sibling. In less than 45 days after launching M-1 Global with the world's greatest fighter, we will participate in one of biggest nights of MMA sports worldwide and begin a great partnership with HDNet Fights and Mark Cuban to bring international M-1 Global fights to North America."

"Today's announcement with M1 Global/Fedor clearly demonstrates that HDNet Fights is committed to working on a unified basis to deliver the best fighters and the best fights," said Andrew Simon, CEO of HDNet Fights.

Mark Cuban, owner of HDNet Fights said, "This announcement reinforces our commitment to becoming the home for LIVE MMA action. No one else in the U.S. but HDNet will have the return of Fedor LIVE from Japan. We started December with "HDNet Fights: Ring of Combat from Atlantic City" and we are ending the month halfway across the world in Japan with the return of the world's best fighter - Fedor. What could be better?"
