Market Wire, September, 2006

Mainframe Entertainment, Inc. ("Mainframe") (TSX: MFE), Canada's leading computer generated (CG) animation production company, today announced that it has mailed an Information Circular to its shareholders with respect to a special meeting of shareholders to be held on Thursday, October 26, 2006 at 10:00 a.m. at Mainframe's offices in Vancouver, British Columbia. At the special meeting, shareholders will be asked to approve, by special resolution, the amalgamation of Mainframe and a newly formed subsidiary of RNK Capital Limited Partnership ("RNK"), which in turn, is a subsidiary of Rainmaker Income Fund ("Rainmaker") (TSX: RNK-un).

The amalgamation is to occur pursuant to a plan of arrangement under the Canada Business Corporations Act. The proposed amalgamation follows the previously announced acquisition by RNK of a 62% interest in Mainframe on July 31, 2006. The net effect of the plan of arrangement is that each common share of Mainframe (other than common shares held by the Rainmaker Group) will be acquired by RNK at a price of $0.24 per share (less any tax required to be deducted and withheld by RNK in respect of shareholders not resident in Canada).

The amalgamation must be approved by a two-thirds majority of shareholders voting at the special meeting and a simple majority of shareholders other than RNK or its affiliates.

The Information Circular contains disclosure regarding the current business activities of the Company for review by Shareholders, including the intended "greenlighting" of a feature length film to be produced by Mainframe.

A copy of the information circular will be available on SEDAR at www.sedar.com and on the Company's website at www.mainframe.ca .
