Interest. The Bonds are multi-modal variable rate bonds that were initially issued in a SIFMA Index Mode, effective January 7, 2015 and expiring on September 13, 2017 by election of the City. The Bonds are being remarketed in a Term Mode having a duration of 4* years (accruing interest through November 30, 2021*; such interest period applicable to the Bonds, as remarketed, the "Current Term Mode Interest Period") and, upon the conclusion thereof, will again be remarketed into a successive Interest o circumstances shall this Preliminary Remarketing Memorandum constitute an offer to sell sell to offer an constitute Memorandum Remarketing Preliminary this shall o circumstances Mode (defined herein) of a to-be-determined duration.

See the table appearing on page ii of this Remarketing Memorandum for a description of the Bonds’ Term Rate during the Current Term Mode Interest Period, as well as the Current Term Mode Interest Period’s effective date, ending date, mandatory tender date, yield, Stepped Rate (defined herein), and CUSIP Number applicable to the Bonds, as remarketed. As the Bonds will be remarketed into a Term Mode, interest on the Bonds during the Current Term Mode Interest Period will be calculated on the basis of a 360-day year of twelve 30-day months and will be payable on each February 1 and August 1, commencing February 1, 2018, along with an irregular final interest payment on the Bonds on December 1, 2021* (being the day immediately following the last day of the Current Term Mode Interest Period).

At the conclusion of the Current Term Mode Interest Period, the Bonds are, on December 1, 2021*, subject to mandatory tender, without right of retention by the Holders (defined herein) thereof (subject to the description below under "No Liquidity Support"). During the Current Term Mode Interest Period, the Bonds are not subject to optional or mandatory tender. The Bonds are subject to redemption at the times, in the amounts and upon conditions described herein. See "THE BONDS – Conversion of Interest Modes (Including Current Conversion); Mandatory Tender; Purchase of Tendered Bonds" and "THE BONDS - Redemption of Bonds". No Liquidity Support. During the Current Term Mode Interest Period, the Bonds are not subject to the benefit of a liquidity facility provided by a third party. Accordingly, a failure by the Remarketing Agent (defined herein) to remarket the Bonds subject to mandatory tender at the end of the Current Term Mode Interest Period will result in the rescission of the notice of mandatory tender with respect thereto and the City not having any obligation to purchase such mandatorily-tendered Bonds at that time. The occurrence of the foregoing will not result in an event of default under the Ordinance or the Bonds. Until such time as the City redeems or remarkets such Bonds that have not been successfully remarketed as described above, those Bonds shall bear interest at the "Stepped Rate", which is identified on page ii of this Remarketing Memorandum, calculated on the basis of a 365 or 366-day year and the number of days actually elapsed. See "THE BONDS - Conversion of Interest Modes (Including Current Conversion); Mandatory Tender; Purchase of Tendered Bonds – Mandatory Tender" herein. Tender; Remarketing. All tenders of Bonds must be made to U.S. Bank National Association, Dallas, Texas, as tender agent for the Bonds (the "Tender Agent"). In the Ordinance, the City has reserved the right to appoint a substitute remarketing agent for the Bonds (which is not required to be the Remarketing Agent identified below) prior to the commencement of the requisite remarketing period applicable to the Bonds and to occur before the expiration of the Current Term Mode Interest Period. Bonds tendered for purchase at the conclusion of the Current Term Mode Interest Period will be bought from the proceeds derived from the remarketing of such Bonds, if any; provided, however, that should the date for tender of the Bonds occur on an Interest Payment Date (defined herein), the accrued interest portion of the Purchase Price (defined herein) is to be paid by the City. Security. The Bonds are special obligations of the City payable solely from and equally and ratably secured, together with the currently outstanding Junior Lien Obligations (defined herein) and any Additional Junior Lien Obligations (defined herein) hereafter issued by the City, by a junior lien on and pledge of the Net Revenues (defined herein) of the City's Electric and Gas Systems (as further described herein, the "Systems"), subject and subordinate to liens and pledges securing the outstanding Senior Lien Obligations and any Additional Senior Lien Obligations (defined herein) hereafter issued, and superior to the pledge and lien securing the currently outstanding Commercial Paper Obligations (defined herein) and Inferior Lien Obligations (defined herein), all as fully set forth in the Ordinance. The City has reserved the right to grant equal and ratable liens on and pledges of Net Revenues to secure payment of Additional Junior Lien Obligations hereafter issued in accordance with the Ordinance (see "THE BONDS – Bond Provisions - Authority and Security for the Bonds"). Conversion. The Ordinance provides that the Bonds are, at the conclusion of the then-effective interest rate mode (other than the Fixed Mode (defined herein), but including the Current Term Mode Interest Period), subject to conversion to another interest rate mode. If the Bonds are converted, in whole or in part, to an interest rate mode other than another Term Mode, a SIFMA Index Mode (defined herein), or a Fixed Mode, the City anticipates entering into an agreement providing liquidity support for those Bonds at such time. No such agreement, however, has been entered into at this time, nor is one expected to be entered into in the future. The Bonds were originally delivered to the initial purchasers together with the approving opinion of the Attorney General of the State of Texas and the approval of certain legal matters by Fulbright & Jaworski LLP and Escamilla & Poneck, LLP, as original co-bond counsel to the City.
