5

2.2    Subordination. Notwithstanding any other provision to the contrary, payment of the Loan principal is subordinate to payment of the Bond Obligations and no cash payment of interest may be made at any time that an “Event of Default” (as defined in either Bond Agreement) exists. Until payment in full of the Bond Obligations, Borrower shall not pay and Lender may not receive and retain any payment of Loan principal.

2.3    Payments of Principal. Borrower shall pay the Loan principal, together with accrued interest on the unpaid Loan principal, in full on the later of (i) January 1, 2022 and (ii) the first Business Day following payment in full of the Bond Obligations.

2.4    Prepayments. The Loan will not be redeemable, payable or prepayable prior to January 1, 2022.

2.5    Accrual and Payment of Interest. Interest shall accrue from day to day on the outstanding Loan principal amount outstanding from time to time at the rate of 10% per annum. Accrued and unpaid interest shall be due and payable by Borrower to Lender quarterly on each March 31, June 30, September 30 and December 31 as follows: (i) following payment in full of the Bond Obligations, in immediately available funds and (ii) during the period until the Bond Obligations are paid in full, (A) one-half in immediately available funds and (B) the balance by delivery of that number of Borrower’s Common Units equal to the result of dividing such balance due by the VWAP Price determined as of the date such balance is due. The foregoing notwithstanding, upon the election of the Lender, some or all of the portion of accrued interest described in item (ii)(B) of this Section 2.5 may be paid in immediately available funds provided that if, within one hundred and seventy-five (175) days of such payment, Borrower has not received net proceeds from the sale of equity equal to the amount of such payment (such proceeds having not otherwise been identified or designated as proceeds off-setting any other dividend, loan payment or other cash distribution by Borrower), then Lender shall within five days purchase from Borrower that number of Borrower’s Common Units equal to the shortfall in such net proceeds, at the VWAP Price per Common Unit determined as of the date of the purchase. If any cash payment of interest required under this Section 2.5 is prohibited by Section 2.2, the amount of such cash payment owing shall be added to the Loan principal as of the date such cash payment is due. On the date hereof, current accrued and unpaid interest is equal to USD $1,444,444. Notwithstanding anything to the contrary, the Original Lender shall be entitled to payment of all accrued and unpaid interest through the Closing Date (as defined in the Investment Agreement).

2.6    Default Interest. Upon and following any Event of Default, all amounts payable hereunder shall bear interest at the rate of 12% per annum from the date of such Event of Default until such amount is paid in full.

2.7    Place of Payments. Except as otherwise provided in Section 2.5, all payments to be made by Borrower to Lender under this Note shall be made to Lender in immediately available funds at its office first noted above, or at such other place as Lender shall designate in writing.
