Valuation Methodology Used by DAI Management Consultants, Inc.
("DAI").

- The fair market value (FMV) , exclusive of the cash grant,
was determined from a blend of the FMV as determined using the enterprise
valuation income approach , also known as the free cash flows-to-equity
approach, and the replacement cost;

- The total project values were deternined by adding the US
Federal cash grant to the FMV;

- The total Value of Equity was determined by adding the total
project values to balance sheet assets such as debt service reserves and
working capital and subtracting senior debt and construction bridge loans;

- Valuation figures are based on completion and assumes
projects will be completed as planned;

- The US dollar equity valuations were translated to Canadian
dollars using an exchange rate of US$1=C$.9832 for Phase I and US$1=C$.9691
for Phase II.

Risks

- Market conditions may change or the owner may not locate
markets at the appraised values;

- This appraisal is not a guarantee of a sale price;
