Additional Details on the Joint Venture and the Assumption of Debt 

GIC and DIR have formed a limited partnership, Dream Summit Industrial LP (the "Purchaser"), with an ownership structure of 90% and 10%, respectively.

A subsidiary of Dream Unlimited Corporation ("Dream") (TSX:DRM) will be the asset manager for the Joint Venture and DIR will provide property management, accounting, construction management, and leasing services to the Joint Venture at market rates.

Concurrent with closing of the Arrangement and pursuant to the trust indenture and indentures supplemental thereto governing the REIT's 2.15% series A debentures due September 17, 2025, 1.82% series B debentures due April 1, 2026, 2.25% series C debentures due January 12, 2027 and 2.44% series D debentures due July 14, 2028 (collectively, the "Debentures"), the Purchaser has assumed the Debentures as successor entity to the REIT. In connection with the assumption, the REIT and the Purchaser, among others, have entered into a supplemental indenture.

As a result of the assumption of the Debentures, the Purchaser became liable in place of the REIT for the payment of all of the Debentures and interest payments on the Debentures, and the REIT has been released from all of its obligations. The Purchaser became a reporting issuer in all of the provinces and territories of Canada other than Ontario upon the assumption of the Debentures.
