DATED: DATE OF INITIAL DELIVERY DUE: AS SHOWN ON PAGE i

The City of Seattle, Washington (the “City”), will issue its Municipal Light and Power Refunding Revenue Bonds, 2018B-1 (SIFMA Index),
2018B-2 (SIFMA Index), 2018C-1 (SIFMA Index), and 2018C-2 (SIFMA Index) (collectively, the “Bonds”), as fully registered bonds without
coupons under a book-entry only system, registered in the name of Cede & Co. as bond owner and nominee for The Depository Trust Company,
New York, New York (“DTC”). DTC will act as initial Securities Depository for the Bonds. Individual purchases of the Bonds will be made
in Book-Entry Form, in denominations of $5,000 or any integral multiple thereof within a maturity of the Bonds. Purchasers will not receive
certificates representing their interest in the Bonds.
The Bonds of each Series will initially bear interest at the applicable Adjusted SIFMA Rate as discussed herein, for the applicable Initial Index
Floating Rate Period, subject to prior optional redemption on or after the applicable Par Call Date, as described herein. At the end of the
applicable Initial Index Floating Rate Period, the Bonds are subject to mandatory purchase, as described herein. The Bonds are also subject
to mandatory purchase and Conversion to a new Index Floating Rate or to the Daily Interest Rate, Weekly Interest Rate, or Long-Term Interest
Rate on or after the applicable Par Call Date, as described herein. See page i of this Official Statement for the Adjusted SIFMA Rate, Index
Floating Rate Spread, Initial Reoffering Price, Scheduled Mandatory Tender Date, and Par Call Date for each Series of the Bonds. This
Official Statement describes each Series of the Bonds only during its Initial Index Floating Rate Period. No Credit Facility secures
payment of the Purchase Price of any Bonds that are not remarketed at the end of their respective Initial Index Floating Rate Period;
however, any Bonds that are not purchased when tendered at the end of the applicable Initial Index Floating Rate Period are subject
to a Stepped Interest Rate. See “Description of the Bonds—Mandatory Tender for Purchase at End of the Initial Index Floating Rate Period”
and “—Redemption of Bonds—Optional Redemption.”
Both principal of and interest on the Bonds are payable in lawful money of the United States of America. Interest on each Series of the Bonds
is payable on the first Business Day of each month, commencing October 1, 2018, until the end of its Initial Index Floating Rate Period, prior
redemption, or Conversion to a new Index Floating Rate or to another interest rate mode. The principal and Purchase Price of and interest on
the Bonds are payable by U.S. Bank National Association, Seattle, Washington, as Bond Registrar/Paying Agent, to DTC, which is obligated
to remit such principal, Purchase Price, and interest to its broker-dealer participants for subsequent disbursement to Beneficial Owners of the
Bonds. See “Description of the Bonds—Registration and Book-Entry Form” and “—Payment of Bonds” and Appendix F—Book-Entry
System.
The Bonds are being issued to refund certain variable rate bonds of the City’s municipal light and power plant and system (the “Light System”)
and to pay the costs of issuing the Bonds and administering the Refunding Plan. See “Use of Proceeds.”
The Bonds are subject to redemption prior to maturity as described herein. See “Description of the Bonds—Redemption of Bonds.”
The Bonds are issued as Parity Bonds and are special limited obligations of the City payable from and secured solely by Gross Revenues of
the Light System available after payment of Operating and Maintenance Expense (“Net Revenue”) and by money in the Parity Bond Fund and
the Reserve Fund. The pledge of Net Revenue to pay and secure the Parity Bonds constitutes a lien and charge upon Net Revenue prior and
superior to all other charges whatsoever. The Bonds will be issued on parity with the Outstanding Parity Bonds and all Future Parity Bonds.
Operating and maintenance expense includes the unconditional obligation of the City to make payments under certain power purchase
contracts, as more fully described in “Power Resources and Cost of Power—Purchased Power Arrangements.” See “Security for the Bonds.”
The Bonds do not constitute general obligations of the City, the State of Washington (the “State”), or any political subdivision of the
State, or a charge upon any general fund or upon any money or other property of the City, the State, or any political subdivision of
the State not specifically pledged thereto by the legislation authorizing the issuance of the Bonds. Neither the full faith and credit nor
the taxing power of the City, nor any revenues of the City derived from sources other than the Light System, are pledged to the
payment of the Bonds.
The Bonds are offered for delivery by the Underwriter of the Bonds when, as, and if issued, subject to the approving legal opinion of Stradling
Yocca Carlson & Rauth, a Professional Corporation, Seattle, Washington, Bond Counsel. The form of Bond Counsel’s opinion is attached
hereto as Appendix C. Certain legal matters will be passed upon for the Underwriter by its counsel, Orrick, Herrington & Sutcliffe LLP,
Seattle, Washington. It is expected that the Bonds will be available for delivery at DTC’s facilities in New York, New York, or delivered to
the Bond Registrar/Paying Agent on behalf of DTC for closing by Fast Automated Securities Transfer, on or about September 4, 2018.

amount not to exceed 125% of the par amount to be refunded thereby. The Bond Ordinance further delegates to the
Director of the Finance Division of the City’s Department of Finance and Administrative Services (the “Director of
Finance”) the authority to execute, on behalf of the City, a Bond Purchase Agreement with the Underwriter, a Paying
Agency Agreement (which incorporates the Addendum) with the Bond Registrar/Paying Agent, and other related

ending on ___________, for the Series B Bonds, and _______________, for the Series C Bonds (each, the “ Scheduled
Mandatory Tender Date”), subject to prior optional redemption or Conversion to a new Index Floating Rate or to
another interest rate mode, as described herein. The Adjusted SIFMA Rate is the SIFMA Index plus the Index Floating
Rate Spread as set forth on page i. Interest will be determined each Wednesday (or, if any such Wednesday is not a
Business Day, the next succeeding Business Day), and the Bonds will bear interest at that rate from the immediately
following Thursday through the next Wednesday. This Official Statement describes the Bonds only during the
Initial Index Floating Rate Period.

The Bonds will be issued in denominations of $5,000 or any integral multiple thereof (“Authorized Denominations”).

redemption, or Conversion to another Interest Rate Period. Interest on the Bonds will be computed on the basis of a
365-day or 366-day year for the actual days elapsed during the Initial Index Floating Rate Period. Principal and
interest is paid to the Registered Owners as of the Record Date, which for the Bonds in the Initial Index Floating Rate
Period is the 15th day immediately preceding an Interest Payment Date.

At the end of each Series’ Initial Index Floating Rate Period, such Series of the Bonds is subject to mandatory purchase,
as further described herein, and such Series of the Bonds may be redeemed or converted to a new Index Floating Rate
or another interest rate mode. See page i of this Official Statement for the maturity date, Initial Reoffering Price,
Adjusted SIFMA Rate, Index Floating Rate Spread, Maximum Interest Rate, Scheduled Mandatory Tender Date, and
Par Call Date for each Series of the Bonds. See “—Other Interest Rate Modes and Conditions for Conversion” for a
summary of the interest rate modes authorized by the Bond Documents, as set forth in the Addendum (see
Appendix B), and the conditions for Conversion.

No Credit Facility secures payment of the Purchase Price of Bonds of any Bonds that are not remarketed at the
end of their respective Initial Index Floating Rate Period; however, any Bonds that are not purchased when
tendered at the end of the applicable Initial Index Floating Rate Period are subject to a Stepped Interest Rate. See
“Mandatory Tender for Purchase at End of the Initial Index Floating Rate Period.”

Registration and Book-Entry Form
Book-Entry Form. The Bonds initially will be issued in Book-Entry Form and registered in the name of the Securities

Depository or the persons for whom they act as nominees with respect to the Bonds regarding the accuracy of any
records maintained by the Securities Depository or its participants of any amount in respect of principal of or interest
on the Bonds, or any notice which is permitted or required to be given to Registered Owners under the Bond Ordinance
(except such notice as is required to be given by the Bond Registrar/Paying Agent to the Securities Depository).
