Resolve Business Outsourcing Income Fund Files Final Prospectus

TORONTO, CANADA - March 13, 2006 - FirstService Corporation (TSX: FSV.SV) and Resolve Business Outsourcing Income Fund (the “Fund”) announced today that the Fund has filed a final prospectus with the securities commissions in each of the provinces and territories of Canada in connection with its initial public offering of 22,500,000 ordinary trust units of the Fund (the “Units”) at a price of $10.00 per Unit for total gross proceeds of $225,000,000. All amounts are in Canadian dollars. The Fund also granted to the underwriters of the offering an over-allotment option to acquire within 30 days following closing an additional 2,250,000 Units on the same terms and conditions.

The Fund will use the proceeds of the offering to acquire Resolve Corporation and its subsidiaries (collectively, “Resolve”) from FirstService. Concurrently, the Fund will acquire CSRS Holdings, Ltd. (“CSRS”) from its investor group. After giving effect to the offering, the Fund will indirectly hold an approximately 70.5% interest in the combined Resolve/CSRS business (77.3% if the underwriters’ over-allotment option is exercised in full), and FirstService, the CSRS investor group, and senior management will hold the remaining interest. Of this retained interest, FirstService will hold an approximately 7% interest in the combined Resolve/CSRS business, and will receive approximately $130,200,000 of cash proceeds (including repayment of intercompany indebtedness) as a result of the sale of its stake in Resolve (a 2% interest and $147,300,000 of cash proceeds, if the underwriters’ over-allotment option is exercised in full).

The closing of the offering is subject to customary conditions and is expected to occur on March 17, 2006. The Units are to be listed for trading on the Toronto Stock Exchange under the symbol RBO.UN.

The securities offered have not been, and will not be, registered under the United States Securities Act of 1933, as amended, and may not be offered or sold in the United States absent registration or any applicable exemption from the registration requirement of such Act. This press release shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of these securities in any jurisdiction in which such offer, solicitation or sale would be unlawful.
