[1] The Partnership’s guaranty is for 50% of the loan balance. The Partnership has guaranteed up to 100% of the outstanding loan balance upon the occurrence of fraud or other willful misconduct by the borrower or if the borrower voluntarily files for bankruptcy. The guaranty agreement requires the Partnership to maintain a minimum net worth of not less than $100.0 million and maintain liquid assets of not less than $5.0 million. The Partnership was in compliance with these requirements as of December 31, 2021. The Partnership has also provided indemnification to the lender for various costs including environmental non-compliance and remediation during the term.

[2] The initial maturity is September 2022, though the borrower may extend the maturity date for one 6-month period.
