TORONTO–(BUSINESS WIRE)–Slate Office REIT (TSX: SOT.UN) (the “REIT”) announced today that it has
entered into an agreement to sell 895 Waverley Street and 1000 Waverley
Street in Winnipeg, Manitoba for a combined sale price of $21.3 million.
The REIT expects to use the net proceeds to reduce outstanding debt and
to fund continued unit repurchases.

“The disposition of 895 Waverley Street and 1000 Waverley Street
demonstrate the REIT’s ability to generate meaningful returns for
unitholders,” said Scott Antoniak, the REIT’s Chief Executive Officer.
“The dispositions are consistent with our plan to strategically recycle
capital to reduce debt and create liquidity for future opportunities.”

Disposition Highlights

  19%.
• The disposition price is at an 8.1% premium to the REIT’s IFRS value.
• These dispositions, in addition to the previously announced joint
  venture in the Greater Toronto Area, provide further validation for
  the net asset value of the REIT.
• The transaction is expected to close in the second quarter of 2019.

Normal Course Issuer Bid (“NCIB”) Update

• To date in 2019, the REIT has invested $11.3 million to repurchase and
  cancel approximately 1.8 million units. The repurchases have been
  completed at a weighted average price of $6.10 per unit.

  significant discount to the REIT’s net asset value and represent a
  compelling investment opportunity.
