Loans. Upon the terms and subject to the conditions of this Agreement, the Lender hereby establishes a discretionary revolving credit facility for the Borrower (the “Facility”), pursuant to which the Lender, on a discretionary and uncommitted basis, agrees to consider advancing, from time to time during the period from the date hereof through the Business Day immediately preceding the Maturity Date (the “Facility Period”), amounts in Dollars to the Borrower (the “Loans”), the aggregate outstanding principal amount of which shall not exceed $100,000,000 (the “Maximum Facility Amount”) at any time. Within the limits set forth in the preceding sentence and subject to the conditions of this Agreement, amounts of Loans that are repaid may be re-borrowed under this Section 1. Following the Lender's receipt of a Loan Request from the Borrower pursuant to Section 6, the Lender will advise the Borrower if it agrees to advance the requested Loan. If the Lender confirms that it will advance such Loan, then upon the fulfillment of the further conditions specified in Section 6, such Loan shall be disbursed by the Lender on the requested date therefor (which shall be a Business Day) in Dollars in funds immediately available to the Borrower in such manner as shall be reasonably requested by the Borrower and reasonably acceptable to the Lender. 2. Interest. Interest on each Loan shall accrue at the Interest Rate from the date of such Loan until such Loan is repaid in full. Interest shall be calculated on the basis of a year of 365/366 days, as the case may be, and the actual number of days elapsed and shall be payable in cash on the first Business Day of each calendar quarter, beginning on July 1, 2020, or, if earlier, on the date on which the outstanding principal amount of such Loan is repaid or prepaid in accordance with the terms hereof but no later than the Maturity Date. 3. Repayment; Termination; Exchange or Redemption. (a) Maturity. The Borrower promises to repay the entire unpaid principal amount of all Loans and all accrued but unpaid interest on the Maturity Date or, if earlier, upon the obligations hereunder becoming due pursuant to the last paragraph of Section 9. (b) Voluntary Prepayment. The Borrower may, at any time and from time to time, prepay, without premium or penalty, the Loans in whole or in part, together with accrued interest to the date of such prepayment on the aggregate principal prepaid. Each prepayment of the Loans by the Borrower pursuant to this Section 3(b) shall be allocated first to accrued but unpaid interest on such Loans to the date of such prepayment and then to unpaid principal amounts outstanding under such Loans.

DOC ID - 51409746.5 -2- (c) Reduction; Termination.

The Borrower may, at any time, by written notice to the Lender, terminate the Facility or the Facility Period, provided that, on the effective date of the termination of the Facility, all of the Loans, all accrued interest thereon and all other obligations of the Borrower hereunder have been paid in full. (d) Exchange or Redemption.
