Mr. Temerty may be considered to have control or direction over the balance of the Common Shares described above.

Mr. Temerty and, to his knowledge, the other owners of shares described in this news release, have no intention of disposing of any shares of NPI, except that NPHI intends to donate a number of the Common Shares to the Temerty Family Foundation, a charitable foundation of which he and other family members are the directors. NPHI, Mr. Temerty's wife and one of his daughters intend to continue to participate in Northland's dividend reinvestment plan, thereby acquiring ownership of more Common Shares of Northland.
