MINT ANNOUNCES THIRD QUARTER 1999 DISTRIBUTION

MINT is pleased to announce that a distribution of $0.20 per trust unit will be payable on October 29, 1999 to unitholders of record on September 30, 1999. This equates to a 12.3% annualized yield based on the current market price of $6.50. It is anticipated that distributions for the remainder of 1999 will continue at this level.

Unitholders of MINT can acquire additional units by participating in the Distribution Reinvestment Plan. The Plan enables unitholders to reinvest their quarterly distributions in additional units of MINT thereby achieving the benefit of compounding returns. In order to take advantage of the Plan, unitholders should contact their investment advisor or Middlefield.

MINT trades on the Toronto Stock Exchange under the symbol "MID.UN".
