Catalyst Fund's Latest Action Follows Seven Previous Unsuccessful

Attempts to Trigger Company Default

TORONTO, Oct. 31 /PRNewswire-FirstCall/ - IMAX Corporation (NASDAQ:IMAX; TSX:IMX) today characterized the latest in a long series of attempts by a single Company bondholder to place the Company in default under its debt covenants and disrupt its business as a publicity stunt.

For over seven months, Catalyst Fund Limited Partnership has been seeking to find ways to default the Company under the indenture ("Indenture") governing its $160 million of 9 5/8% Senior Notes due December 1, 2010 (the "Senior Notes"). After an unsuccessful attempt to oppose the Company's April 2007 consent solicitation to its bondholders, and seven failed attempts to trigger a default under the Indenture, Catalyst now purports to accelerate the maturity of the Senior Notes, despite the fact that it has no rights or grounds to do so under the Indenture.

In May, Catalyst disregarded the explicit limitations of the Indenture and began filing lawsuits against the Company. First, it filed a civil action in New York, claiming that IMAX committed fraud in connection with the solicitation process. Then, in September, Catalyst filed an application in Canada that repeated the allegations made in New York and moved to discontinue its New York proceeding.

IMAX has at all times complied with the Indenture covenants and the cure periods provided therein. The Company remains in compliance with the Indenture and no default or event of default (as those terms are defined in the Indenture) has occurred or is continuing.
