Milestone Apartments REIT Closes Internalization Transaction and Renews Base Shelf Prospectus

10/3/16

Milestone Apartments Real Estate Investment Trust (TSX: MST.UN) announced that it has completed the previously announced internalization of the REIT's asset management function and also filed and obtained a receipt for a final base shelf prospectus. All dollar amounts are in U.S. currency unless otherwise noted.

Internalization

With closing of the Internalization, the REIT's operating partnership has acquired the REIT's asset manager, TMG Partners L.P. (the "Asset Manager") for $25.0 million in cash, which is being funded with a drawdown on the REIT's revolving line of credit, and approximately 5.3 million class B limited partnership units of the REIT's operating partnership ("Class B Units"), which are redeemable on a one-for-one basis for trust units of the REIT ("Units"), subject to a minimum hold period. The aggregate consideration of $106.5 million was based on the Toronto Stock Exchange 10-day volume weighted average price of the REIT's units ended July 25, 2016 (the day prior to the announcement of the Internalization) of C$20.20 and a US$ to C$ exchange rate of US$1 to C$1.3225 based on the Bank of Canada's noon U.S. dollar exchange rate as at July 25, 2016.

At a special meeting of unitholders of the REIT ("Unitholders") held on September 13, 2016, Unitholders overwhelmingly voted in favour of the Internalization with the Internalization approved by over 99% of votes cast by Unitholders. Affiliates of the Asset Manager abstained from voting on the Internalization.

Prior to closing, the Asset Manager was indirectly owned by Robert P. Landin and Jeffrey L. Goldberg. Prior to closing, Messrs. Landin, Goldberg and their joint actors (including MST Investors, LLC) directly and indirectly owned or exercised control or direction over 19,500 Units and 5,513,675 Class B Units, which together represented an approximate 7.3% ownership interest in the REIT on a partially diluted basis (assuming all Class B Units held by Messrs. Landin, Goldberg and their joint actors were redeemed for Units). Following closing, Messrs. Landin, Goldberg and their joint actors (including MST Investors, LLC) directly and indirectly own or exercise control or direction over 19,500 Units and 10,850,938 Class B Units, which together represent an approximate 13.4% ownership interest in the REIT on a partially diluted basis (assuming all Class B Units held by Messrs. Landin, Goldberg and their joint actors were redeemed for Units). Messrs. Landin, Goldberg and their joint actors have informed the REIT that the REIT securities owned by them are held for investment purposes and that they may, subject to market conditions and in compliance with applicable securities laws, make additional investments in, or dispositions of, securities of the REIT. A copy of the early warning reports required to be filed by Messrs. Landin and Goldberg with applicable securities commissions will be filed under the REIT's profile on SEDAR at www.sedar.com and a copy of the early warning reports may also be obtained by contacting Robert Debs, the REIT's Director of Investor Relations, at 5429 LBJ Freeway, Suite 800, Dallas, TX 75240, or 214-561-1215.
