Barclays Professional Sports Team will provide a £20million funding facility for the stadium and a £50million loan towards a capital fund for structural development in the game.
The South Stand Development comprises a 156-bed Marriott Hotel, a 40,000 sq. ft. Virgin Active fitness & leisure club, conference & banqueting facilities, a destination Rugby Store and a performing arts theatre for the local community.
It is expected to be open to the public from November 2006.
The RFU will fund approximately £80million from its own resources.
The £50million loan will be used as a development fund for the professional and amateur games. Funds could, for example, go towards stadium development for Guinness Premiership clubs.
However, the RFU looks to be on another collision course with the clubs over player release.
It insists England players should not be released from the Six Nations tournament to take part in the Powergen Cup semi-finals on March 4.
