[1] This LP constructed, owns and operates the Texoma Medical Plaza II, on which construction substantially completed in December 2020. The MOB is located in Denison, Texas, on the campus of a hospital owned and operated by a wholly-owned subsidiary of UHS. We have committed to invest up to $5.2 million in equity and debt financing, $2.2 million of which has been funded as of December 31, 2023. This LP entered into a third-party construction loan commitment, which is non-recourse to us, which has an outstanding balance of $12.8 million as of December 31, 2023. Monthly principal and interest payments on this loan commenced on January 1, 2023. During the first quarter of 2024, $5.7 million of the third-party construction loan was repaid utilizing pro rata equity contributions from the partners. The third-party partner's share of the pro rata equity contributions was partially funded with a six-month, $128,000 partner loan from us. Our share of the pro rata equity contributions, as well as the third-party partner loan, were funded utilizing borrowings from our revolving credit agreement. As a result of the repayment of a portion of the construction loan, an associated $3.1 million letter of credit was terminated.

[2] We are the lessee with a UHS-related party for the land related to this property.

[3] UHS has one 5-year renewal option at existing lease rates (through 2031).
