Note: Starting N.A.V. per $100 unit is normally $80.00 after subtracting costs of issue and premiums, so an N.A.V. above $80.00 per unit represents appreciation in the portfolio.

* For a Québec resident and assuming maximum offering is achieved.
1 Return based on marginal tax rate of 48.21%.

NOTES AND ASSUMPTIONS: (1) Capital gains can be offset by unused capital losses, so for investors with sufficient unused capital losses, this is the final after-tax return. (2) On national Pathway mining offerings calculated with reference to an Ontario investor paying income tax at the highest marginal rate of 46.41%, and using the "money-at-risk/after-tax purchase cost" as the denominator and the dissolution value minus the "money-at-risk/after-tax purchase cost" as the numerator; in the case of Québec offerings the "money-at-risk/after-tax purchase cost" used in the prospectus was applied; assumes the full purchase cost of the flow-through investment can be deducted by investors for income tax purposes. (3) Calculated with reference to an Ontario investor paying income tax at the highest marginal rate of 46.41%, and using the same process as in note (2), except that the numerator also has the capital gains tax amount deducted from the numerator; assumes one-half of capital gains are taxable, and the adjusted cost base of each limited partnership unit is nil. (4) Returns are calculated without factoring in the time value of money, and also are not annualized. (5) The general partner's back-end bonus entitlement has already been removed.
