(a) Subject to the provisions of this Section, wherever in this Fifty -Fifth Supplement a calculation of Subordinate Lien Debt Service during any current or future Subordinate Lien Debt Service Accrual Period with respect to Subordinate Lien Interim Obligations is required by application of the Standard Assumptions, the Subordinate Lien Debt Service shall be computed by assuming that the principal amount of the Subordinate Lien Interim Obligations, excluding the Subordinate Lien Initial Interim Obligations, will be continuously refinanced and will remain Outstanding until the first Fiscal Year for which interest on the Subordinate Lien Obligations has not been capitalized or otherwise funded or provided for, at which time it shall be assumed (A) that the Outstanding principal amount of the series of such Subordinate Lien Interim Obligations will be refinanced with a series of Additional Subordinate Lien Obligations that will be amortized over a period not to exceed 30 years in such manner as will cause the maximum Subordinate Lien Debt Service Requirement applicable to such series in any twelve (12) month period not to exceed 110% of the minimum Subordinate Lien Debt Service Requirements applicable to such series for any other twelve (12) month period, and (B) that the series of Additional Subordinate Lien Obligations will bear interest at a fixed interest rate estimated by the Board's financial advisor to be the interest rate such series of Additional Subordinate Lien Obligations would bear if issued on such terms on the date of such estimate. Notwithstanding anything herein to the contrary, for the purposes of setting rates, fees and charges under Section 6.3 for the then current Fiscal Year, the Board may assume an interest rate that is equal to the average rate over the last twelve months plus 50 basis points. With respect to Subordinate Lien Initial Interim Obligations, the Subordinate Lien Debt Service shall be computed using the reasonable assumptions established by an Authorized Officer. Additionally, such Subordinate Lien Initial Interim Obligations shall not be subject to the requirements of Article III of this Fifty -Fifth Supplement. (b) Subject to the last sentence of this Section, wherever in this Fifty -Fifth Supplement a calculation of Subordinate Lien Debt Service during any current or future Subordinate Lien Debt Service Accrual Period with respect to each series of Subordinate Lien Variable Interest Rate Obligations that are not Subordinate Lien Interim Obligations is required by application of the Standard Assumptions, the Subordinate Lien Debt Service shall be computed by assuming that such Subordinate Lien Obligations will bear interest at an interest rate which, in the judgment of an Authorized Officer, is the average rate anticipated to be in effect with respect to such Subordinate Lien Variable Interest Rate Obligations; provided, however, for the purpose of verifying prior compliance with the rate covenants contained in paragraphs 6.3 (b) and (c) of the Fifty -Fifth Supplement, such Subordinate Lien Obligations shall be deemed to bear interest at the actual rate home during any prior test period. Notwithstanding anything herein to the contrary, for the purposes of setting rates, fees and charges under Section 6.3 for the then current Fiscal Year, the Board may assume an interest rate that is equal to the average rate over the last twelve months plus 50 basis points. (c) Subject to the last sentence of this Section, wherever in this Fifty -Fifth Supplement calculation of Subordinate Lien Debt Service during any current or future Subordinate Lien Debt Service Accrual Period with respect to Subordinate Lien Balloon Obligations is required by application of the Standard Assumptions, the Subordinate Lien Debt Service shall be computed by assuming that (A) the principal amount E of such Subordinate Lien Balloon Obligations will be amortized over a term of not more than 30 years, as determined by an Authorized Officer, extending not later than 30 years from the date such Subordinate Lien Balloon Obligations were originally issued, and (B) such Subordinate Lien Balloon Obligations will bear interest at a fixed interest rate estimated by the Board's financial advisor to be the interest rate such series of Subordinate Lien Balloon Obligations would bear if issued on such terms on the date of such estimate. Notwithstanding any to the contrary, for the purposes of setting rates, fees and charges under Section 6.3 for the then current Fiscal Year, the Board may assume an interest rate that is equal to the average rate over the last twelve months plus 50 basis points.

(b) Additional Supplemental Ordinances adopted related to Subordinate Lien Obligations for any ofthe purposes permitted by this Section need not, in order to be valid, be signed or accepted by any other Person.

Section 8.3 Powers of Amendment. Any modification or amendment of this Fifty -Fifth Supplement and ofthe rights and obligations ofthe Cities and the Board and ofthe Subordinate Lien Holders may be made by an Additional Supplemental Ordinance, with the written consent (i) of the Subordinate Lien Holders of a majority ofthe combined principal amount ofthe Subordinate Lien Obligations then Outstanding, or (ii) in case less than all ofthe several series of Subordinate Lien Obligations then Outstanding are affected by the modification or amendment, of the Subordinate Lien Holders of a majority in principal amount of the Subordinate Lien Obligations of each series so affected and Outstanding at the time such consent is given; provided, however, no such modification or amendment shall permit a change in the terms of redemption or maturity of the principal of any Outstanding Subordinate Lien Obligation, or of any installment of interest thereon, or a reduction in the principal amount of the Redemption Price thereof, or in the rate of interest thereon, without the consent of such Subordinate Lien Holder, and provided further that no such modification or amendment may be made without the prior written consent of such ofthe Credit Providers as are granted the right of such consent under the provisions of an Additional Supplemental Ordinance. The Cities must obtain and receive an opinion of bond counsel selected by the Cities as conclusive evidence as to whether Subordinate Lien Obligations of any particular series or maturity would be so affected by any such modification or amendment of this Fifty -Fifth Supplement. The Cities must obtain and receive an opinion of bond counsel selected by the Cities that, to the extent majority Holder consent is not sought, for whatever reason, the amendments, whether pursuant to Section 8.2 or 8.4 herein, do not adversely affect Holders or Credit Providers holding Parity Credit Agreement Obligations. To the extent any amendment will have a material adverse effect on Holders or Credit Providers holding Parity Credit Agreement Obligations, such amendment will require the written consent of a majority of Holders and the consent of all Credit Providers holding Parity Credit Agreement Obligations. Section 8.4 Consent of Holders or Credit Providers. (a) The Cities may at any time adopt an Additional Supplemental Ordinance related to Subordinate Lien Obligations making a modification or amendment permitted by the provisions of Section 8.3 of this Fifty -Fifth Supplement, to take effect when and as provided in this subsection (a) or in subsection (b) of this Section. A copy of such Additional Supplemental 26 Ordinance (or brief summary thereof or reference thereto) together with a request for consent addressed to the Subordinate Lien Holders whose consent is required, shall promptly after adoption be mailed by the Board to the appropriate Subordinate Lien Holders (but failure to mail such copy and request shall not affect the validity of the Additional Supplemental Ordinance when consented to as herein provided). Such Additional Supplemental Ordinance shall not be effective unless and until the Board shall have received the written consents of the proper Subordinate Lien Holders having the percentages specified in Section 8.3. Any such consent shall be continuously binding upon the Subordinate Lien Holder giving such consent and upon any subsequent Subordinate Lien Holder thereof and of any Subordinate Lien Obligations issued in exchange therefor (whether or not such subsequent Subordinate Lien Holder thereof has notice thereof), unless such consent is revoked in writing by the Subordinate Lien Holder giving such consent or a subsequent Subordinate Lien Holder thereof by filing with the Board, prior to the time action is taken in response to such consents. At any time thereafter notice, stating in substance that the Additional Supplemental Ordinance (which may be referred to as an Additional Supplemental Ordinance adopted by the Cities on a stated date) has been consented to by the Subordinate Lien Holders of the required percentages of Subordinate Lien Obligations and will be effective as hereinafter provided, shall be given to the Subordinate Lien Holders (whose consent was required) by the Board by mailing such notice to such Subordinate Lien Holders (but failure to mail such notice shall not prevent such Additional Supplemental Ordinance from becoming effective and binding). The Additional Supplemental Ordinance making such amendment or modification shall be conclusively binding upon the Cities, the Board, each Paying Agent, all Subordinate Lien Holders, and all Credit Providers holding Credit Agreement Obligations related to Subordinate Lien Obligations at the expiration of 30 days after the mailing by the Board of such last mentioned notice, except in the event of a final decree of a court of competent jurisdiction setting aside such Additional Supplemental Ordinance in a legal action or equitable proceeding for such purpose commenced within such 30 day period; provided, however, that the Cities, the Board and any Paying Agent during such 30 day period and any such further period during which any such action or proceeding may be pending shall be entitled in their reasonable discretion to take such action, or to refrain from taking such action, with respect to such Additional Supplemental Ordinance as they may deem expedient. (b) Unless the right is limited by the terms of an Additional Supplemental Ordinance, the Cities reserve and shall have the continuing right to amend this Fifty -Fifth Supplement under Section 8.3 and this Section, without the consent of or notice to the Subordinate Lien Holders under subsection (a) of this Section, if such amendment is approved by each Credit Provider holding Credit Agreement Obligations related to Subordinate Lien Obligations which is existing at the time the amendment is proposed by the Cities. Such right is hereby granted to such Credit Providers and the exercise of such right shall require no further action. Section 8.5 Mailing of Notice. Any notice to Subordinate Lien Holders or Holders under this Article is sufficient if (i) it is mailed first class postage prepaid to each registered owner of Subordinate Lien Holders or Holders at the address, if any, appearing upon the Obligation Registers, or (ii) for any Obligations or Subordinate Lien Obligations held in book -entry -only form, delivery to the securities depository (or its nominee) in accordance with the depository's procedures, which constitutes notice to all beneficial owners. Notice to each Credit Provider may be given by any of the foregoing methods or as provided in the applicable Credit Agreement. The failure of any Holder, Subordinate Lien Holder or beneficial owner to receive notice, or any defect in a notice, does not affect the validity of the action if the notice was sent as provided above. Section 8.6 Exclusion of Subordinate Lien Obli atg ions. Subordinate Lien Obligations owned or held by or for the account of the Cities will not be deemed Outstanding for the purpose of consent or other action or any calculation of Outstanding Subordinate Lien Obligations provided for in this Fifty -Fifth Supplement, and the Cities shall not be entitled with respect to such Subordinate Lien Obligations to give any consent or take any other action provided for in this Fifty -Fifth Supplement. 27 ARTICLE IX DISCHARGE OF ORDINANCE Section 9.1 Reserved.
