1. 
Purchase and Sale of the Obligations.  The Issuer’s Utility Systems Revenue 
Refunding Obligations, Series 2026 (the “Obligations”) shall be executed and delivered pursuant 
to a Trust Agreement, to be dated as of [May] 1, 2026 (the “Trust Agreement”), between the Issuer 
and UMB Bank, n.a., as trustee (in such capacity, the “Trustee”), and Resolution No. [____], 
passed and adopted by the City Council of the City on [April 6], 2026 (the “Authorizing 
Resolution”).  The Obligations represent undivided proportionate interests in an Installment 
Purchase Agreement, to be dated as of [May] 1, 2026 (the “Purchase Agreement”), between UMB 
Bank, n.a., in its capacity as seller, and the Issuer, as purchaser, and the payments made by the 
Issuer under the Purchase Agreement.   
Subject to the terms and conditions and in reliance upon the representations, 
warranties and agreements set forth herein, the Underwriter hereby agrees to purchase from the 
Issuer, and the Issuer hereby agrees to cause the sale and delivery to the Underwriter, all, but not 
less than all, of the Obligations.  Inasmuch as this purchase and sale represents a negotiated 
transaction, the Issuer acknowledges and agrees that: (i) the Underwriter is not acting as municipal 
advisor within the meaning of Section 15B of the Securities Exchange Act, as amended, (ii) the 
primary role of the Underwriter, as underwriter, is to purchase securities, for resale to investors, in

2 
 1106455581\2\ 
an arm’s length commercial transaction between the Issuer and the Underwriter and the 
Underwriter has financial and other interests that differ from those of the Issuer; (iii) the 
Underwriter is acting solely as a principal and is not acting as a municipal advisor, financial advisor 
or fiduciary to the Issuer and has not assumed any advisory or fiduciary responsibility to the Issuer 
with respect to the transaction contemplated hereby and the discussions, undertakings and 
procedures leading thereto (irrespective of whether the Underwriter has provided other services or 
is currently providing other services to the Issuer on other matters); (iv) the only obligations the 
Underwriter has to the Issuer with respect to the transaction contemplated hereby expressly are set 
forth in this Purchase Contract; and (v) the Issuer has consulted its own financial and/or municipal, 
legal, accounting, tax and other advisors, as applicable, to the extent it has deemed appropriate. 
The Underwriter has been duly authorized to execute this Purchase Contract and to act hereunder.  
The principal amount of the Obligations to be executed and delivered, the dated date therefor, the 
initial interest payment date, the maturities, the redemption provisions and interest rates per annum 
and resulting yields are set forth in Schedule I hereto.   
The purchase price for the Obligations shall be $________, representing the 
aggregate of (i) the par amount of the Obligations, [plus][less] (ii) the [net] reoffering 
[premium][discount] on the Obligations of $_________ and less (iii) an underwriting discount of 
$________. 
[For convenience, the Underwriter shall pay by the Closing Date (as defined 
herein), on behalf of the Issuer, $_________ from the proceeds of the Obligations to the Insurer 
(as defined herein) as payment of the bond insurance premium for the Policy (as defined herein).] 
2. 
Public Offering.  The Underwriter intends to make an initial public offering of the 
Obligations at a price not in excess of the initial offering price or prices or yields not less than the 
yields set forth on the inside front cover page of the Official Statement of the Issuer; provided, 
however, the Underwriter reserves the right to change such initial public offering price or prices 
as the Underwriter deems necessary or desirable, in its sole discretion, in connection with the 
marketing of the Obligations (but in all cases subject to the requirements of Section 3 hereof), and 
may offer and sell the Obligations to certain dealers, unit investment trusts and money market 
funds, certain of which may be sponsored or managed by the Underwriter at prices lower than the 
public offering prices or yields greater than the yields set forth therein (but in all cases subject to 
the requirements of Section 3 hereof).   
3. 
Establishment of Issue Price. 
(a) 
The Underwriter agrees to assist the Issuer in establishing the issue price of 
the Obligations and shall execute and deliver to the Issuer at Closing (as defined herein) an “issue 
price” or similar certificate, substantially in the form attached hereto as Exhibit A, together with 
the supporting pricing wires or equivalent communications, with such modifications as may be 
deemed appropriate or necessary, in the reasonable judgment of the Underwriter, the Issuer and 
Special Counsel, to accurately reflect, as applicable, the sales price or prices or the initial offering 
price or prices to the public of the Obligations.  All actions to be taken by the Issuer under this 
section to establish the issue price of the Obligations may be taken on behalf of the Issuer by the 
Issuer’s municipal advisor identified herein and any notice or report to be provided to the Issuer 
may be provided to the Issuer’s municipal advisor.

3 
 1106455581\2\ 
(b) 
[Except for the maturities set forth in Schedule [II] attached hereto,] the 
Issuer represents that it will treat the first price at which 10% of each maturity of the Obligations 
[(the “10% Test”)] is sold to the public as the issue price of that maturity (if different interest rates 
apply within a maturity, each separate CUSIP number within that maturity will be subject to the 
10% Test).  [If, as of the date hereof, the 10% Test has not been satisfied as to any maturity of the 
Obligations for which the Issuer has elected to utilize the 10% Test, the Underwriter agrees to 
promptly report to the Issuer the prices at which it sells the unsold Obligations of that maturity to 
the public.  That reporting obligation shall continue until the earlier of the date upon which the 
10% Test has been satisfied as to the Obligations of that maturity or maturities or the Closing 
Date.]] 
 
 
[(c) 
The Underwriter confirms that it has offered the Obligations to the public 
on or before the date of this Purchase Contract at the offering price or prices (the “initial offering 
price”), or at the corresponding yield or yields, set forth in Schedule [II] attached hereto, except as 
otherwise set forth therein.  Schedule [II] also sets forth, as of the date of this Purchase Contract, 
the maturities, if any, of the Obligations for which the 10% Test has not been satisfied and for 
which the Issuer and the Underwriter agrees that the restrictions set forth in the next sentence shall 
apply (the “hold-the-offering-price rule”).  So long as the hold-the-offering-price rule remains 
applicable to any maturity of the Obligations, the Underwriter will neither offer nor sell unsold 
Obligations of that maturity to any person at a price that is higher than the initial offering price to 
the public during the period starting on the sale date and ending on the earlier of the following:  
(1) 
the close of the fifth (5th) business day after the sale date; or  
(2) 
the date on which the Underwriter has sold at least 10% of that maturity of 
the Obligations to the public at a price that is no higher than the initial offering price to the 
public.] 
[(c)][(d)] 
The Underwriter confirms that: 
(1) 
any selling group agreement and any third-party distribution agreement 
relating to the initial sale of the Obligations to the public, together with the related pricing 
wires, contains or will contain language obligating each dealer who is a member of the 
selling group and each broker-dealer that is a party to such third-party distribution 
agreement, as applicable: 
(A)(i) to report the prices at which it sells to the public the unsold 
Obligations of each maturity allocated to it until either all Obligations of that 
maturity allocated to it have been sold or it is notified by the Underwriter that the 
10% Test has been satisfied as to the Obligations of that maturity and (ii) to comply 
with the hold-the-offering-price rule, if applicable, in each case if and for so long 
as directed by the Underwriter and as set forth in the related pricing wires, and 
(B) 
to promptly notify the Underwriter of any sales of 
Obligations that, to its knowledge, are made to a purchaser who is a related party 
to an underwriter participating in the initial sale of the Obligations to the public 
(each such term being used as defined below), and

4 
 1106455581\2\ 
(C) 
to acknowledge that, unless otherwise advised by the dealer 
or broker-dealer, the Underwriter shall assume that each order submitted by the 
dealer or broker-dealer is a sale to the public. 
(2) 
any selling group agreement relating to the initial sale of the Obligations to 
the public, together with the related pricing wires, contains or will contain language 
obligating each dealer that is a party to a third-party distribution agreement to be employed 
in connection with the initial sale of the Obligations to the public to require each broker-
dealer that is a party to such third-party distribution agreement to (A) report the prices at 
which it sells to the public the unsold Obligations of each maturity allocated to it until 
either all Obligations of that maturity allocated to it have been sold or it is notified by the 
Underwriter that the 10% Test has been satisfied as to the Obligations of that maturity and 
(B) comply with the hold-the-offering-price rule, if applicable, [in each case] if and for so 
long as directed by the Underwriter and as set forth in the related pricing wires.    
The Issuer acknowledges that, in making the representations set forth in this section, the 
Underwriter will rely on (i) in the event a selling group has been created in connection with the 
initial sale of the Obligations to the public, the agreement of each dealer who is a member of the 
selling group to comply with the requirements for establishing issue price of the Obligations, 
including, but not limited to, its agreement to comply with the hold-the-offering-price rule, if 
applicable to the Obligations, as set forth in a selling group agreement and the related pricing 
wires, and (ii) in the event that a third-party distribution agreement that was employed in 
connection with the initial sale of the Obligations to the public, the agreement of each broker-
dealer that is a party to such agreement to comply with the requirements for establishing issue 
price of the Obligations, including, but not limited to, its agreement to comply with the hold-the-
offering-price rule, if applicable, as set forth in the  third-party distribution agreement and the 
related pricing wires.  The Issuer further acknowledges that the Underwriter shall not be liable for 
the failure of any broker-dealer that is a party to a third-party distribution agreement, to comply 
with its corresponding agreement to comply with the requirements for establishing issue price of 
the Obligations, including, but not limited to, its agreement to comply with the hold-the-offering-
price rule, if applicable to the Obligations.]   
 
 
[(d)][(e)] 
The Underwriter acknowledges that sales of any Obligations to any 
person that is a related party to an underwriter participating in the initial sale of the Obligations to 
the public (each such term being used as defined below) shall not constitute sales to the public for 
purposes of this section.  Further, for purposes of this section:

“public” means any person other than an underwriter or a related party to 
an underwriter, 
(2) 
“underwriter” means (A) any person that agrees pursuant to a written 
contract with the Issuer (or with the lead underwriter to form an 
underwriting syndicate) to participate in the initial sale of the Obligations

directly or indirectly with a person described in clause (A) to participate in 
the initial sale of the Obligations to the public (including a member of a

 1106455581\2\ 
selling group or a party to a third-party distribution agreement participating 
in the initial sale of the Obligations to the public), [and] 
(3) 
a purchaser of any of the Obligations is a “related party” to an underwriter 
if the underwriter and the purchaser are subject, directly or indirectly, to (A) 
more than 50% common ownership of the voting power or the total value 
of their stock, if both entities are corporations (including direct ownership 
by one corporation of another), (B) more than 50% common ownership of 
their capital interests or profits interests, if both entities are partnerships 
(including direct ownership by one partnership of another), or (C) more than 
50% common ownership of the value of the outstanding stock of the 
corporation or the capital interests or profit interests of the partnership, as

of the other)[.][and

Appendices thereto, of the Issuer relating to the Obligations has been provided to the Underwriter.  
Such Preliminary Official Statement, as amended to reflect the changes required in connection 
with the pricing and sale of the Obligations, is hereinafter called the “Official Statement.” 
(b) 
The Preliminary Official Statement has been prepared for use by the 
Underwriter in connection with the public offering, sale and distribution of the Obligations.  The 
Issuer hereby deems the Preliminary Official Statement “final” as of its date, except for the 
omission of such information which is dependent upon the final pricing of the Obligations for 
completion, all as permitted to be excluded by Section (b)(1) of Rule 15c2-12 under the Securities 
Exchange Act of 1934 (the “Rule”). 
(c) 
The Issuer represents that it has reviewed and approved the information in 
the Official Statement and hereby authorizes the Official Statement and the information therein 
contained to be used by the Underwriter in connection with the public offering and the sale of the 
Obligations.  The Issuer consents to the use by the Underwriter prior to the date hereof of the 
Preliminary Official Statement in connection with the public offering of the Obligations.  The 
Issuer shall provide, or cause to be provided, to the Underwriter as soon as practicable after the 
date of the Issuer’s acceptance of this Purchase Contract (but, in any event, not later than within 
seven (7) business days after the Issuer’s acceptance of this Purchase Contract and in sufficient 
time to accompany any confirmation that requests payment from any customer) copies (including 
electronic copies) of the Official Statement which is complete as of the date of its delivery to the

comply with Section (b)(4) of the Rule and the rules of the Municipal Securities Rulemaking Board 
(“MSRB”).  The Issuer shall prepare the Official Statement, including any amendments thereto, in

6 
 1106455581\2\ 
word-searchable PDF format as described in the MSRB’s Rule G-32 and shall provide the 
electronic copy of the word-searchable PDF format of the Official Statement to the Underwriter 
no later than one (1) business day prior to the Closing to enable the Underwriter to comply with 
MSRB Rule G-32.  The Issuer hereby confirms that it does not object to the distribution of the 
Official Statement in electronic form.  
(d) 
If, after the date of this Purchase Contract to and including the date the 
Underwriter is no longer required to provide an Official Statement to potential customers who 
request the same pursuant to the Rule (the earlier of (i) 90 days from the “end of the underwriting 
period” (as defined in the Rule) and (ii) the time when the Official Statement is available to any 
person from the MSRB, but in no case less than 25 days after the “end of the underwriting period” 
for the Obligations), the Issuer becomes aware of any fact or event which might or would cause 
the Official Statement, as then supplemented or amended, to contain any untrue statement of a 
material fact or to omit to state a material fact required to be stated therein or necessary to make 
the statements therein not misleading, or if it is necessary to amend or supplement the Official 
Statement to comply with law, the Issuer will notify the Underwriter (and for the purposes of this 
clause provide the Underwriter with such information as it may from time to time request), and if, 
in the opinion of the Underwriter, or the Issuer, such fact or event requires preparation and 
publication of a supplement or amendment to the Official Statement, the Issuer will forthwith 
prepare and furnish, at the Issuer’s own expense (in a form and manner approved by the 
Underwriter), a reasonable number of copies of either amendments or supplements to the Official 
Statement so that the statements in the Official Statement as so amended and supplemented will 
not contain any untrue statement of a material fact or omit to state a material fact required to be 
stated therein or necessary to make the statements therein not misleading or so that the Official 
Statement will comply with law.  If such notification shall be subsequent to the Closing, the Issuer 
shall furnish such legal opinions, certificates, instruments and other documents as the Underwriter 
may reasonably deem necessary to evidence the truth and accuracy of such supplement or 
amendment to the Official Statement. 
(e) 
The Underwriter hereby agrees to file the Official Statement with the 
Electronic Municipal Market Access system of the MSRB.  Unless otherwise notified in writing 
by the Underwriter, the Issuer can assume that the “end of the underwriting period” for purposes 
of the Rule is the Closing Date (as defined herein).

undertake, pursuant to the Continuing Disclosure Undertaking, dated as of the Closing Date (the 
“Continuing Disclosure Undertaking”), executed by the Issuer, to provide annual financial 
information and notices of the occurrence of specified events.  A description of the Continuing 
Disclosure Undertaking is set forth in, and a form of such agreement is attached as an appendix to, 
the Preliminary Official Statement and the Official Statement.

the Official Statement, as of its date and as of the Closing Date, contained
