The obligation of the Company to make payments with respect to the principal of and premium, if any, and interest on bonds of the Twentieth Series, including any obligation to redeem, or pay upon acceleration, all or a portion of the principal amount of bonds of the Twentieth Series prior to maturity, shall be fully or partially, as the case may be, satisfied and discharged to the extent that the equivalent amounts due under the Sweetwater Loan

Agreement with respect to the Series 1984 Bonds shall have been fully or partially paid. Satisfaction of any obligation under the bonds of the Twentieth Series to the extent that payment is made with respect to the Sweetwater Loan Agreement means that if any payment is made under the Sweetwater Loan Agreement, a corresponding payment obligation with respect to the principal of and premium, if any, or interest on bonds of the Twentieth Series (including any obligation to redeem, or pay upon acceleration, all or a portion of the principal amount of bonds of the Twentieth Series prior to maturity), shall be deemed discharged in the same proportion and amount as such payment discharges the outstanding obligations with respect to the Sweetwater Loan Agreement.

The Trustee may conclusively presume that no such Event of Default has occurred or has been waived or cured or that the consequences thereof have not been rescinded or annulled unless and until the Trustee shall have received a written notice from the trustee under the Series 1984 Indenture, signed by a Chairman, President or any Vice President thereof, stating that one or more of such Events of Default has occurred or has been waived or cured or that the consequences thereof have been rescinded or annulled.

Upon any transfer or exchange of bonds of the Twenty-First Series, the Company may make a charge therefor sufficient to reimburse it for any tax or taxes or other government charge, as provided in Section 2.08 of the Mortgage, but the Company hereby waives any right to make a charge in addition thereto for any exchange or transfer of bonds of the Twenty-First Series.

(IX) After the execution and delivery of this Fifteenth Supplemental Indenture and upon compliance with the applicable provisions of the Mortgage and this Fifteenth Supplemental Indenture, it is contemplated that there shall be an issue of bonds of the Twenty-First Series in an aggregate principal amount not to exceed Eight Million Five Hundred Thousand Dollars ($8,500,000).
