ATS'S Photowatt Technologies Business Enters 10 Year Silicon Supply Agreement


CAMBRIDGE, ON, Oct. 16- ATS Automation Tooling Systems Inc. today
announced that its solar business, Photowatt Technologies, has entered into a
10-year silicon supply contract with Deutsche Solar AG, Freiberg for the
supply of solar-grade, multi-crystalline polysilicon wafers beginning in the
first half of calendar 2009. Deutsche Solar is one of Europe's largest wafer
manufacturers and a subsidiary of SolarWorld AG.

Under the agreement, Deutsche Solar is obliged to deliver, and Photowatt
Technologies is obliged to accept, approximately four million polysilicon
wafers per annum. These wafers will be processed into solar cells and modules
by Photowatt and are estimated to support the manufacture of approximately
15 megawatts of solar power products per annum. Advance payments to be made
under the contract will be applied against the price of silicon wafers
received during the life of the commitment. The price will be adjusted at the
beginning of each calendar year based upon an agreed formula. Management
believes that these terms are reflective of current commercial terms in the
solar industry for supply contracts of similar durations.
