 SECTION 1.        DESCRIPTION OF SERIES 2006 BONDS. 

The Series 2006 Bonds will be issued pursuant to a Trust Indenture dated as of December 1, 2006, (the
“Indenture”), from the Authority to U.S. Bank National Association, as trustee (the “Trustee”), and are to be payable solely from the “Revenues” and the moneys available under the Indenture, being principally payments
required to be made under a Loan

Agreement, dated as of December 1, 2006 (the “Agreement”), by and between the Authority and the Company. To evidence its payment obligations under the Agreement, the Company will
execute and deliver its Project Note, dated as of December 1, 2006 (the “Project Note”), to the Trustee. The Company’s obligations under the Loan Agreement and the Project Note are further secured by a Security Agreement dated as
of December 1, 2006 (the “Security Agreement”) from the Company to the Trustee. In connection with the issuance of the Series 2006 Bonds, the Company will execute and deliver an Intercreditor Agreement, to be dated the Closing Date
(as herein defined), among the Company, the Trustee and Wells Fargo Bank, N.A. (the “Bank”) in its capacity as “Lender” under that certain Amended and Restated Credit Agreement, dated as of December 9, 2005, between the Bank
and the Company and other affiliated entities, as supplemented and amended (the “Bank Credit Agreement”). 
 In
the Loan Agreement, the Company agrees to make payments from, and in the Security Agreement, the Company pledges to the Trustee for the payment of the Series 2006 Bonds, all of its rights to the “Income Available for Debt Service,” which
constitutes all of the Company’s rights to receive the Palo Verde Receipts and the Santa Cruz Receipts (each as defined in the Loan Agreement). 

The proceeds of the sale of the Series 2006 Bonds will be loaned to the Company to reimburse the costs of the acquisition,
construction and equipping of water and wastewater treatment facilities to be owned and utilized by the Company or by Palo Verde or Santa Cruz (each as defined in the Loan Agreement and collectively, the “Project Subsidiaries”), to fund
the Bond Reserve Fund and to pay certain costs incurred in connection with the issuance of the Series 2006 Bonds. 
 The
Series 2006 Bonds will be dated, will be in an aggregate principal amount, will mature on December 1 in the years and principal amounts, will bear interest at the rates and will be subject to optional, extraordinary and mandatory redemption,
all as set forth in Exhibit A hereto and shall otherwise be as described in the Limited Offering Memorandum, dated the date hereof (the “Limited Offering Memorandum”), as relating to the offering of the Series 2006 Bonds. 

SECTION 2.        PURCHASE, SALE AND OFFERING OF THE SERIES 2006 BONDS. 

Subject to the terms and conditions and in reliance upon the representations, warranties and agreements set forth herein, the
Purchaser hereby agrees to purchase from the Authority, and the Authority hereby agrees to sell and deliver to the Purchaser, all (but not less than all) of the Series 2006 Bonds. The Authority’s obligation to issue the Series 2006 Bonds shall
be conditioned on the understanding that all opinions and certificates under Section 7 hereof shall include the Authority as an addressee or expressly allow for reliance thereon by the Authority. 

The aggregate purchase price of the Series 2006 Bonds shall be $35,460,000.00, less Purchaser’s compensation of
$1,035,000.00, with $729,900.00 being paid at the Closing from proceeds of the Series 2006 Bonds and the remaining $305,100.00 being paid at the Closing from other funds contributed by the Company (the “Purchase Price”).

 The Purchaser agrees to make a bona fide public offering of the Series 2006 Bonds
at the offering prices or yields not in excess of those set forth in Exhibit A hereto. The Purchaser may offer a portion of the Series 2006 Bonds for sale to selected dealers who are members of the National Association of Securities Dealers, Inc.
and who agree to resell the Series 2006 Bonds to the public on terms consistent with this Bond Purchase Agreement. The Purchaser reserves, however, the right, in its sole discretion, to change such offering prices or yields as the Purchaser shall
deem necessary in connection with the offering of the Series 2006 Bonds and to offer and sell the Series 2006 Bonds to certain dealers (including the Purchaser and other dealers depositing the Series 2006 Bonds into investment trusts) and others at
prices lower than the initial offering prices or at yields higher than the initial yields set forth in the Limited Offering Memorandum (as such term is hereinafter defined). The Purchaser also reserves the right (a) to over allot or effect
transactions that stabilize or maintain the market price of the Series 2006 Bonds at a level above that which might otherwise prevail in the open market and (b) to discontinue such stabilizing, if commenced, at any time. A “bona fide
public offering” shall include an offering to a representative number of institutional investors or registered investment companies, regardless of the number of such investors to which the Series 2006 Bonds are sold. 

SECTION 3.        CLOSING. 

At 8:00 a.m., Mountain Standard Time, on December 28, 2006, or such other time or on such earlier or later date as the
Authority, the Company and the Purchaser mutually agree on (the “Closing Date” or “Closing”), the Authority will cause the Trustee to deliver to the Purchaser, at the office of The Depository Trust Company (“DTC”), New
York, New York, or at such other place to which the Authority, the Company and the Purchaser may agree mutually, the Series 2006 Bonds in definitive form (all the Series 2006 Bonds to be type written in authorized denominations and registered in the
name of Cede & Co.), duly executed and authenticated against payment therefor in immediately available funds by the Purchaser to the Trustee. 

It is anticipated that CUSIP identification numbers will be printed on the Series 2006 Bonds, but neither the failure to print
such numbers on any Series 2006 Bond or any error with respect thereto shall constitute cause for a failure or refusal by the Purchaser to accept delivery of the Series 2006 Bonds in accordance with the terms of this Bond Purchase Agreement. 

The Series 2006 Bonds will be made available to the Purchaser for checking and packaging as soon as practicable, but at least
by 12:00 noon, on the business day prior to the Closing Date at the office of DTC or at such other place to which the parties hereto may agree mutually. 

On the Closing Date, the Purchaser will accept delivery of the Series 2006 Bonds and will pay to the order of the Trustee the
Purchase Price in immediately available funds. 
 The Purchaser agrees to furnish to the Company and the Authority, prior to
the delivery of the Series 2006 Bonds, the initial offering prices of the Series 2006 Bonds to the public and such additional information and certificates as may be reasonably necessary to enable (i) the Authority to determine the “issue
price” of the Series 2006 Bonds for purposes of determining the yield on the Series 2006 Bonds within the meaning of Section 148 of the Internal Revenue 

  
 3 

 
Code of 1986, as amended (the “Code”), and (ii) Kutak Rock LLP, as Bond Counsel, to determine the amount of original issue discount, if any, on the Series 2006 Bonds.

(ii) the Authority and the Company agree that (1) if any event relating to or which might affect the correctness or completeness of the Warranted Information contained in the Limited Offering Memorandum; (2) if any event shall occur
as a result of which the Warranted Information contained in the Limited Offering Memorandum as then amended or supplemented contains an untrue statement of a material fact or omits to state a material fact necessary in order to make such statements
therein, in the light of the circumstances when the Limited Offering Memorandum is delivered to a purchaser, not misleading or (3) if the Purchaser, the Authority or the Company is notified that such an event has occurred, then the Purchaser,
the Authority or the Company, as applicable (but, with respect to the Authority, only as the foregoing relates to the Authority Warranted Information), shall promptly notify the Purchaser, the Authority and the Company of the circumstances and
details of such, event. If in the opinion of the Purchaser or the Authority it is necessary to amend or supplement the Limited Offering Memorandum to make the Limited Offering Memorandum not misleading in light of the circumstances existing at the
time it is delivered to a purchaser or potential customer (as defined for purposes of the Rule), the Authority and the Company will, at the request of the Purchaser or the Authority and at the expense of the Company, cooperate with and cause the
preparation of a reasonable number of copies of an amendment of or supplement to the Limited Offering Memorandum (in form and substance satisfactory to the Purchaser and the Authority), that will amend or supplement the Limited Offering Memorandum

to the Closing Date, the Purchaser in its sole discretion shall have the right to terminate its obligations hereunder by written notice to the Authority and the Company and thereafter the Purchaser will be under no obligation to purchase and pay for
any of the Series 2006 Bonds. 
 The Authority and the Company agree, until the end of the Warranty Period, (i) to
notify the Purchaser, the Authority and the Company upon the occurrence of any material event adversely affecting the Authority or the Company, the properties or operations of the Authority or the Company or the consummation of the material
transactions contemplated by the documents and agreements to which the Authority or the Company is a party and (ii) to furnish to the Purchaser and the Authority all such information as may be necessary to amend the Limited Offering Memorandum
as required by this Section.

Unless otherwise notified in writing by the Purchaser by the Closing Date, the Authority and the Company can assume that the “End of the Underwriting Period” for purposes of this Bond Purchase Agreement shall be the Closing Date. In the
event such notice is so given in writing by the Purchaser, the Purchaser agrees to notify the Authority and the Company in writing following the occurrence of the End of the Underwriting Period as defined in the Rule.

SECTION 9.        INDEMNIFICATION BY THE COMPANY. 

(a)        Scope of Indemnification. The Company will indemnify and hold
harmless the Authority, the County, the Purchaser, each director, trustee, partner, member, officer, official or employee or agent thereof and each person, if any, who controls the Purchaser within the meaning of the Securities Act (any such person
being herein sometimes called an “Indemnified Party”), for, from and against any and all losses, claims, damages or liabilities, joint or several, (i) to which any such Indemnified Party may become subject, under any statute or
regulation at law or in equity or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact set forth in the
Limited Offering Memorandum, or any amendment or supplement thereto, or the Preliminary Limited Offering Memorandum or arise out of or are based upon the omission or alleged omission to state in the Company Warranted Information therein a material
fact required to be stated therein or which is necessary to make the statements made therein, in light of the circumstances in which they were made, not misleading in any material respect; and (ii) to the extent of the aggregate amount paid in
any settlement of any litigation commenced or threatened arising from a claim based upon any such untrue statement or alleged untrue statement or omission or alleged omission if such settlement is effected with the written consent of the Company
(which consent shall not be unreasonably withheld); and will reimburse any legal or other expenses reasonably incurred by any such Indemnified Party in connection with investigating or defending any such loss, claim, damage, liability or action.

  
 18 

 (b)        Procedure. An
Indemnified Party shall, promptly after the receipt of notice of a written threat of the commencement of any action against such Indemnified Party in respect of which indemnification may be sought against the Company, notify the Company in writing
of the commencement thereof. Failure of the Indemnified Party to give such notice will reduce the liability of the Company by the amount of damages attributable to the failure of the Indemnified Parry to give such notice to the Company, but the
omission to notify the Company of any such action shall not relieve the Company from any liability that any of them may have to such Indemnified Party otherwise than under this Section. In case any such action shall be brought against an Indemnified
Party and such Indemnified Party shall notify the Company of the commencement thereof, the Company may, or if so requested. by such Indemnified Party shall, participate therein or assume the defenses thereof, with counsel satisfactory to such
Indemnified Party and the Company (it being understood that, except as hereinafter provided, the Company shall not be liable for the expenses of more than one counsel representing the Indemnified Parties in such action), and after notice from the
Company to such Indemnified Party of an election so to assume the defenses thereof, the Company will not be liable to such Indemnified Party under this Section for any legal or other expenses subsequently incurred by such Indemnified Party in
connection with the defense thereof other than reasonable costs of investigation; provided, however, that unless and until the Company assumes the defense of any such action at the request of such Indemnified Party, the Company shall have the right
to participate at its own expense in the defense of any such action. If the Company shall not have employed counsel to have charge of the defense of any such action or if an Indemnified Party shall have reasonably concluded that there may be
defenses available to it and/or other Indemnified Parties that are different from or additional to those available to the Company (in which case the Company shall not have the right to direct the defense of such action on behalf of such Indemnified
Party) or to other Indemnified Parties, legal and other expenses, including the expense of separate counsel, incurred by such Indemnified Party shall be borne by the Company. 

(c)        Contribution. In order to provide for just and equitable
contribution in circumstances in which the indemnification provided for in this Section is applicable but for any reason is held to be unavailable to the Purchaser from the Company, the Company and the Purchaser shall contribute to the aggregate
losses, claims, damages and liabilities (including any investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claims asserted, but after deducting any
contribution received by the Company from persons who control the Company within the meaning of the Securities Act or otherwise) to which the Company and the Purchaser may be subject (i) in such proportion as shall be appropriate to reflect the
relative benefits received by the Company, on the one hand and the Purchaser on the other from the purchase of the Series 2006 Bonds or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Purchaser on the other with respect to the statements or omissions that
resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Purchaser, on the other, shall be deemed
to be in the same proportion as the total net proceeds .from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Purchaser. The relative fault shall be determined
by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission 

  
 19 

 
to state a material fact relates to information supplied by or relating to the Company or the Purchaser, the intent of the parties and their relative knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and the Purchaser agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method
of allocation that does not take into account the equitable consideration referred to herein. Notwithstanding the provisions hereof, the Purchaser shall not be required to contribute any amount in excess of the amount by which the Purchaser’s
compensation exceeds the amount of any damages the Purchaser has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation shall be
entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this paragraph, each person, if any, who controls the Purchaser within the meaning of the Securities Act shall have the same rights to
contribution as the Purchaser and each person, if any, who. controls the Company within the meaning of the Securities Act shall have the same rights to contribution as the Company, subject in each case to clauses (i) and (ii) of this
paragraph. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under
this paragraph, notify such party or parties from whom contribution may be sought, but the omission to so notify such party from whom contribution may be sought shall not relieve the party or parties from whom contribution may be sought from any
other obligation it or they may have hereunder or otherwise than under this Section. No party shall be liable for contribution with respect, to any action or claim settled without its consent. 

SECTION 10.      PAYMENT OF EXPENSES. 

The Purchaser shall be under no obligation to pay, and the Company shall pay or cause to be paid, any and all expenses and
costs incurred in connection with the authorization, issuance or sale of the Series 2006 Bonds, including, but not limited to: costs of preparing, printing and delivering the Preliminary Limited Offering Memorandum and the Final Limited Offering
Memorandum (including the word processing, duplicating and delivery charges incurred by Counsel to the Purchaser in connection with the preparation of preliminary or final drafts thereof); costs of printing, reproducing and binding the Financing

retained by the Company and other costs, charges and fees in connection with the foregoing. 
 In the event that the Series
2006 Bonds are not purchased by the Purchaser for any reason other than a default by the Purchaser hereunder, then the Company shall pay upon demand all expenses which would otherwise be paid, or caused to be paid, by the Company pursuant to this
Section and will reimburse the Purchaser and the Authority for “out-of-pocket”, expenses (including reasonable fees and expenses of Counsel to the Purchaser and Counsel to the 

  
 20 

 
Authority, respectively) that shall have been incurred by any of them in connection with the proposed purchase of the Series 2006 Bonds.

 If optional redemption at a redemption price exceeding 100% of the principal
amount to be redeemed is to take place as of any applicable mandatory redemption date identified in the foregoing section hereof, the Series 2006 Bonds, or portions thereof, to be so redeemed shall be selected by lot prior to the selection by lot of
the Series 2006 Bonds to be redeemed on the same date by operation of mandatory provisions of the foregoing section of this Exhibit A. 
 Optional
Redemption 
 The Series 2006 Bonds maturing before or on December 1, 2017, are not subject to redemption prior to
their stated maturity date. The Series 2006 Bonds maturing after December 1, 2017, may be redeemed prior to maturity, in whole at any time, or in part on any Interest Payment Date, in any order of maturity and by lot within any maturity, by the
Corporation, on or after December 1, 2017 at the redemption price of the principal amount of the Series 2006 Bonds to be redeemed plus interest accrued to the date fixed for redemption. 

Extraordinary Optional Redemption 

The Series 2006 Bonds are also subject to redemption by the Authority in the event of the exercise by the Company of its
option to direct redemption (i) at any time in whole, or (ii) on any Interest Payment Date in part in inverse order of maturity in the event of condemnation of part of the Project as described below, at a redemption price of 100% of the
principal amount of the Series 2006 Bonds redeemed, plus interest accrued to the redemption date, upon occurrence of any of the following events: 

(a)         The Project shall have been damaged or destroyed to such an extent
that, in the Company’s reasonable judgment, (1) it cannot reasonably be expected to be restored, within a period of six months, to the condition immediately preceding such damage or destruction, or (2) its normal use and operation is
reasonably expected to be prevented for a period of six consecutive months. 

(b)         Title to, or the temporary use of, all or a significant part of the
Project shall have been taken under the exercise of the power of eminent domain (1) to such extent that the Project cannot, in the Company’s reasonable judgment, reasonably be expected to be restored within a period of six months to a
condition of usefulness comparable to that existing prior to the taking, or (2) as a result of the taking, normal use and operation of the Project is reasonably expected, in the Company’s reasonable judgment, to be prevented for a period
of six consecutive months or more. 
 (c)         As a result of any changes in
the Constitution of the State, the Constitution of the United States of America, or state or federal laws or as a result of legislative or administrative action (whether state or federal) or by final decree, judgment or order of any court or
administrative body (whether state or federal) entered after the contest thereof by the Authority or the Company in good faith, the Loan Agreement shall have become void or unenforceable or impossible of performance in accordance with the intent and
purpose of the parties as expressed in the Loan Agreement, or if unreasonable burdens or excessive liabilities shall have been imposed with respect to the Project or the operation thereof, including, without limitation, federal, state or other ad
valorem, property, income or other taxes not being imposed on the date of the Loan Agreement other than ad valorem taxes presently levied upon privately owned property used for the same general purpose as the Project. 

  
 A-2 

 (d)         Changes in the economic
availability of raw materials, operating supplies, energy sources, labor, equipment or supplies, or facilities necessary for the efficient operation of the Project for the Project Purposes shall have occurred or technological or other changes shall
have occurred which the Company cannot reasonably overcome or control and which in the Company’s reasonable judgment render the Project uneconomic for the Project Purposes. 

(e)         A public offering with respect to the ownership interests in the
Company. 
 To exercise the Company’s option to redeem Series 2006 Bonds following the occurrence of one of the event
listed in (a) through (d) above, the Company shall give notice to the Authority and to the Trustee specifying the date on which the Company will deliver the funds required for that redemption, which date shall be not more than 90 days from
the date that notice is mailed and shall make arrangements satisfactory to the Trustee for the giving of the required notice of redemption. 

To exercise the Company’s option to redeem Series 2006 Bonds following the occurrence of one of the events listed in
(e) above, the Company shall give notice to the Authority and to the Trustee specifying the date on which the Company will deliver the funds required for that redemption, which date shall be not more than 90 days from the date that the event
described in (e) occurred and shall make arrangements satisfactory to the Trustee for the giving of the required notice of redemption. 

The Company also shall have the option, in the event that title to or the temporary use of a portion of the Project shall be
taken under the exercise of the power of eminent domain, even if the taking is not of such nature as to permit the exercise of the redemption option upon an event specified in (b) above, to direct the redemption, at a redemption price of 100%
of the principal amount of Series 2006 Bonds prepaid, plus accrued interest to the redemption date, of that part of the outstanding principal balance of the Series 2006 Bonds as may be payable from the proceeds (after the payment of costs and
expenses incurred in the collection thereof) received in the eminent domain proceeding, provided, that, the Company shall furnish to the Authority and the Trustee a certificate of a duly qualified independent engineer stating that (1) the
property comprising the part of the Project taken is not essential to continued operations of the Project in the manner existing prior to that taking, (2) the Project has been restored to a condition substantially equivalent to that existing
prior to the taking, or (3) other improvements have been acquired or made which are suitable for the continued operation of the Project. 

Mandatory Redemption Upon a Determination of Taxability 

The Company will be obligated to redeem all outstanding Series 2006 Bonds, within 180 days after the Trustee receives
notification that a “Determination of Taxability” (as defined in the Trust Agreement) has occurred, at 103% of the principal amount of the Series 2006 Bonds outstanding at the time of a Determination of Taxability plus accrued interest to
the redemption date.

FORM OF OPINION OF COUNSEL TO THE AUTHORITY 

[Letterhead of Russo, Russo & Slania] 

December         , 2006 

THE INDUSTRIAL DEVELOPMENT AUTHORITY 
   OF THE COUNTY
OF PIMA 
 Tucson, Arizona 
  

	 	Re:	 The Industrial Development Authority of the County of Pima, Water and
 Wastewater Revenue Bonds (Global Water Resources LLC Project),
 Series
2006 

 Ladies and Gentlemen: 

We have acted as counsel to The Industrial Development Authority of the County of Pima (the “Authority”) in
connection with the issuance and delivery of the above-captioned bonds (the “Bonds”). The Bonds are being issued pursuant to a Trust Indenture, dated as of December 1, 2006 (the “Indenture”) between the
Authority and U.S. Bank National Association (the “Trustee”), and are being sold pursuant to the Bond Purchase Agreement dated December 14, 2006 (the “Bond Purchase Agreement”), executed by the Authority,
Global Water Resources LLC, a Delaware limited liability company (the “Borrower”) and Hutchinson, Shockey, Erley & Co. (the “Underwriter”). Capitalized terms used, and not otherwise defined, herein shall
have the meanings set forth in the Indenture. 
 We are members of the Arizona Bar and serve as general counsel to the
Authority. In connection with the issuance on this date by the Authority of its Bonds, we have examined, among other things, the following: 
  

	 	A.	 Executed counterparts of the Indenture, the Loan Agreement dated as of December 1, 2006, between the Authority and the Borrower (the
“Loan Agreement”), the Bond Purchase Agreement, the Tax Certificate dated the date hereof and various other documents or certificates executed by the Authority in connection with the issuance, sale and delivery of the Bonds
(collectively referred to as the “Authority Documents”); 

  

	 	B.	 The provisions of Title 35, Chapter 5, Arizona Revised Statutes, as amended and supplemented (collectively, the “Act”);

  

	 	C.	 The Articles of Incorporation of the Authority (the “Articles”) and the Bylaws of the Authority (the “Bylaws”);

  
 B-1 

	 	D.	 A copy of the proceedings of record of the Board of Directors of the Authority, including the resolution adopted on December 8, 2006 (the
“Authority Resolution”), in connection with the authorization, issuance, sale and delivery of the Bonds and the Authority Documents; 

  

	 	E.	 A copy of the Limited Offering Memorandum regarding the Bonds (the “Limited Offering Memorandum”); and 

 

	 	F.	 Such other laws, matters and documents as we deem necessary for purposes of this opinion. 

As to questions of fact material to our opinion, we have relied upon the representations of the Authority contained in the
Authority Documents, the Authority Resolution and other certifications of public officials furnished to us without undertaking to verify the same by independent investigation. We have also assumed (i) the genuineness of the signatures not
witnessed, the authenticity of documents submitted as originals, and the conformity to originals of documents submitted as copies, (ii) the legal capacity of all natural persons executing the Authority Documents and (iii) that the
Authority Documents accurately describe and contain the mutual understanding of the parties, and that there are not oral or written statements or agreements that modify, amend, or vary, or purport to modify, amend, or vary, any of the terms of the
Authority Documents. 
 Based upon the foregoing and upon such other information and documents as we believe necessary to
enable us to render this opinion, we are of the opinion that: 
 1.         The
Authority is a duly organized nonprofit corporation designated as a political subdivision under the laws of the State of Arizona, with the requisite corporate power and corporate authority to issue the Bonds, to execute and deliver the Authority
Documents and to carry out and perform its obligations under the Authority Resolution and the Authority Documents. 

2.         The execution and delivery of the Bonds, the Authority Resolution and
the Authority Documents by the Authority have been duly authorized by the Authority and have been duly executed and delivered by the Authority and approved by the Board of Supervisors of Pima County, Arizona. The Authority Resolution has been duly
passed by the Authority, is in full force and effect and has not been repealed by the Authority. 

3.         To the best of our knowledge, no action, suit, proceedings, inquiry at
law or in equity are pending or threatened in any way affecting the existence of the Authority or the titles of its officers to their respective offices, or seeking to restrain or to enjoin the issuance, sale or delivery of the Bonds, or the
collection or application of revenues of the Authority pledged or to be pledged to pay the principal of and interest on the Bonds, or the pledge thereof, or in any way contesting or affecting the validity or enforceability of the Bonds or the powers
of the Authority or its authority with respect to the Bonds. 

  
 B-2 

 4.         The execution and
delivery of any of the Authority Documents and compliance with the provisions thereof, under the circumstances contemplated thereby, (i) do not violate the Act, the Articles, the Bylaws or any law, ordinance, administrative regulation,
judgment, injunction, decree, determination or award, currently in effect of which we have knowledge to which the Authority is subject and (ii) do not and will not in any material respect conflict with or constitute on the part of the Authority
a breach of or default under any indenture, deed of trust, mortgage, agreement, or other instrument of which we have knowledge and to which the Authority is a party. 

5.         Other than the approval of the Pima County, Arizona Board of
Supervisors (which has been obtained), no further consents or approvals are necessary from the Authority for the issuance of the Bonds or the valid execution, delivery or performance of the Authority Documents. The Authority has duly authorized the
use of the Limited Offering Memorandum. 
 6.         Without having undertaken
to determine independently the accuracy or completeness of the statements contained in the Limited Offering Memorandum therein under the captions “THE AUTHORITY” or “ABSENCE OF LITIGATION” as it relates to the Authority, nothing
has come to our attention which would lead us to believe that that portions of the Limited Offering Memorandum under the captions “THE AUTHORITY” or “ABSENCE OF LITIGATION” as it relates to the Authority contains an untrue
statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. 

As counsel for the Authority, we are passing only upon those matters set forth in this opinion and are not passing upon the
accuracy or completeness of any statements made in connection with any offering or sale of the Bonds, except as otherwise specifically set forth herein. 

By letter dated December 6, 2006 to the Attorney General of the State of Arizona (the “Attorney
General”), the Authority notified the Attorney General, as required by A.R.S. Section 35-721 (F), of its intention to issue the Bonds. The Attorney General acknowledged receipt of such notice in a letter dated December 6, 2006. As of
the date hereof, the Authority has not received any notice from the Attorney General to the effect that, in his opinion, the Project does not come within the purview of the Act. 

No other person, other than the addressees, may rely upon this opinion without written consent. 

Respectfully submitted, 

RUSSO, RUSSO & SLANIA, P.C.

The Industrial Development Authority
   of the County of Pima, Arizona 
  

	 	Re:	 The Industrial Development Authority of the County of Pima
 $36,495,000 Water and Wastewater Revenue Bonds (Global Water Resources LLC Project)

 Ladies and Gentlemen: 

We have acted as counsel for Global Water Resources LLC, a Delaware limited liability company authorized to conduct business
in the State of Arizona (the “Borrower”) in matters related to the issuance by The Industrial Development Authority of the County of Pima (the “Authority”) of its Water and Wastewater Revenue Bonds (Global Water Resources LLC
Project) in the aggregate principal amount of $36,495,000 (the “Bonds”). Words and terms used in this opinion letter and not otherwise defined herein are intended to have the meanings assigned to them in the Bond Purchase Agreement, dated
December 14, 2006 (the “Bond Purchase Agreement”), among the Borrower, the Authority and Hutchinson, Shockey, Erley &Co., as underwriter of the Bonds (the “Underwriter”). This letter is delivered as an opinion of counsel
to the Borrower contemplated by Section    (    )(    ) of the Bond Purchase Agreement. 

In connection with our representation of the Borrower, we have examined the law and such documents and matters as we have
deemed necessary to render the opinions expressed in this letter, including, without limitation, originals or copies of: 

(a)         The Loan Agreement, dated as of December 1, 2006 (the “Loan
Agreement”), between the Authority and the Borrower. 
 (b)         The
Trust Indenture, dated as of December 1, 2006 (the “Indenture”), between the Authority and Wells Fargo Bank, N.A., as Bond Trustee (the “Trustee”). 

(c)         The Security Agreement, dated as of December 1, 2006 (the
“Security Agreement”), between the Borrower and the Trustee. 

(d)         The Intercreditor Agreement, dated the date hereof (the
“Intercreditor 

  
 C-1 - Page 1 

 
Agreement”) among the Borrower, the Trustee and Wells Fargo Bank, N.A. 

(e)         The Bond Purchase Agreement. 

(f)         The Tax Exemption Certificate and Agreement, of even date herewith
(the “Tax Regulatory Agreement”); 
 (g)         The Continuing
Disclosure Agreement, dated this date (the “Continuing Disclosure Agreement”), between the Borrower and the Bond Trustee. 

(h)         The Limited Offering Memorandum, dated December 14, 2006 (the
“Limited Offering Memorandum”) with respect to the Bonds. 

(i)         Such corporate documents and records of the Borrower, certificates of
public officials and officers of the Borrower and such other documents as we have deemed necessary or appropriate for the purposes of the opinions expressed in this letter. 

The Loan Agreement, the Security Agreement, the Tax Regulatory Agreement, the Bond Purchase Agreement, the Intercreditor
Agreement and the Continuing Disclosure Agreement are referred to herein collectively as the “Bond Issue Agreements.” The Bond Issue Agreements and the Indenture are referred to herein collectively as the “Agreements.” 

In connection with our examination, we have relied upon and assumed compliance with the provisions of the documents examined,
and we have assumed the accuracy and completeness of the statements, certificates, and representations furnished to us without undertaking to verify the same by independent investigation. We have assumed, and have not verified, (i) the
genuineness of the signatures on all documents, the authenticity of documents submitted as originals, and the conformity to originals of documents submitted as copies; (ii) the legal capacity of all individuals executing the documents;
(iii) that the documents accurately describe the mutual understanding of the parties thereof, and that there are no oral or written statements that modify, amend, or vary, or purport to modify, amend, or vary, any of the terms of the documents;
(iv) that the Borrower own all of the property, assets, and rights purported to be owned by them; and (v) that no interest, charges, fees, or other benefits or compensation in the nature of interest in connection with the transactions
contemplated by the documents will be received other than those that the Borrower has agreed in writing in the Agreements to pay. 

Based upon the foregoing, we are of the opinion, and we herewith advise you, as follows: 

1.         The Borrower is limited liability company duly organized, validly
existing, and in good standing under the laws of the State of Delaware, duly authorized to do business in the State of Arizona, with full legal right, power and authority to execute, deliver, and perform its obligations under the Agreements to which
it is a party. 
 2.         Each of the Bond Issue Agreements have been duly
authorized, executed and delivered on behalf of Borrower and are valid and binding obligations of Borrower enforceable against Borrower in accordance with their respective terms, except as enforceability may be limited by bankruptcy, insolvency,
reorganization, or other similar laws or equitable principles 

  
 C-1 - Page 2 

 
affecting the enforcement of creditors’ rights generally, and except as the enforceability of the indemnifications set forth in the Bond Purchase Agreement may be limited by principles of

Issue Agreements by the Borrower, and the approval by the Borrower of the Bond Indenture, the Bonds and the Limited Offering Memorandum, and compliance by the Borrower with the provisions of the Bond Issue Agreements, do not and will not conflict

material indenture, deed of trust, mortgage, agreement, or other instrument of which the participating attorneys in our firm have knowledge and to which the Borrower is a party or by which the Borrower or its properties is bound, and, to the

 Ladies and Gentlemen: 

We have acted as counsel for Global Water Resources LLC, a Delaware limited liability company authorized to conduct business
in the State of Arizona (the “Borrower”) in matters related to the issuance by The Industrial Development Authority of the County of Pima (the “Authority”) of its Water and Wastewater Revenue Bonds (Global Water Resources LLC

(i)         Such corporate documents and records of the Borrower, certificates of
public officials and officers of the Borrower and such other documents as we have deemed necessary or appropriate for the purposes of the opinions expressed in this letter. 

The Loan Agreement, the Security Agreement, the Tax Regulatory Agreement, the Bond Purchase Agreement, the Intercreditor
Agreement and the Continuing Disclosure Agreement are referred to herein collectively as the “Bond Issue Agreements.” The Bond Issue Agreements and the Indenture are referred to herein collectively as the “Agreements.” 

In connection with our examination, we have relied upon and assumed compliance with the provisions of the documents examined,
and we have assumed the accuracy and completeness of the statements, certificates, and representations furnished to us without undertaking to verify the same by independent investigation. We have assumed, and have not verified, (i) the
genuineness of the signatures on all documents, the authenticity of documents submitted as originals, and the conformity to originals of documents submitted as copies; (ii) the legal capacity of all individuals executing the documents;

	 	Re:	 The Industrial Development Authority of the County of Pima
 Water and Wastewater Revenue Bonds (Global Water Resources, LLC Project),
 Series
2006 (the “Bonds”) 

 Ladies and Gentlemen: 

We have acted as counsel to you in connection with your purchase of $36,495,000 aggregate principal amount of Water and
Wastewater Revenue Bonds (Global Water Resources, LLC Project), Series 2006 (the “Bonds”), issued on this date by The Industrial Development Authority of Pima County (the ‘Issuer”). The Bonds are being issued pursuant to the
terms of the Trust Indenture dated as of December 1, 2006, (the “Indenture”) between the Issuer and Wells Fargo Bank, NA, as trustee. 

Capitalized terms used herein without definition shall have the meanings specified in the Bond Purchase Agreement, dated
December 14, 2006, among the Issuer, Global Water Resources, LLC (the “Company”) and Hutchinson, Shockey, Erley & Co. 

We have rendered legal advice and assistance to you as to the requirements of Rule 15c2-12 prescribed under the Securities
Exchange Act of 1934, as amended (the “Rule”), in connection with your review, for purposes of the Rule, of the Continuing Disclosure Undertaking, dated as of the date hereof (the “Undertaking”) of the Company. Based upon our
examination of the Undertaking, the Rule and such other documents and matters of law as we have considered necessary, we are of the opinion that, under existing law, the Undertaking complies in all material respects with the applicable requirements
of the Rule; provided, however, no view is expressed regarding the items comprising the Annual Report (as defined in the Undertaking). 

Assuming the validity of the Bonds and the exclusion of interest on the Bonds for federal income tax purposes, as set forth in
the opinion of even date herewith of Kutak Rock LLP and based upon our review of such documents and showings and related matters of law as we have deemed necessary and in reliance thereon, we are of the opinion that, under existing law, in
connection with the offering, sale and delivery of the Bonds under the circumstances described in the Limited Offering Memorandum (as defined below), the Bonds and the Loan Agreement are not required to be registered under the Securities Act of
1933, as amended, and the Indenture is not required to be qualified under the Trust Indenture Act of 1939, as amended.

opinions and certificates of officers of the Issuer, the Company and other appropriate persons. We also participated in conferences and telephone conferences with your representatives and other persons involved in the preparation of information for
the Limited Offering Memorandum, during which the contents of the Limited Offering Memorandum and related matters were discussed and revised. While we are not passing upon, and do not assume responsibility for, the accuracy, completeness or fairness
of the statements contained in the Limited Offering Memorandum, based upon our limited review of documents. and participation in conferences as aforesaid, without independent verification, no facts have come to our attention which lead us to believe
that the Limited Offering Memorandum (apart from (i) the information relating to The Depository Trust Company and its book-entry-only system and (ii) the financial, operating and statistical data contained therein, as to all of which we do
not express any opinion or belief) contained as of its date or contains as of the date hereof any untrue statement of a material fact or omitted or omits to state a material fact required to be stated therein or necessary in order to make the
statements made therein, in the light of the circumstances under which they were made, not misleading. 
 This letter is

 This offer is made subject to acceptance by
the Authority and the Company prior to 11:59 p.m. (Mountain Standard Time) on the date hereof or such other time as is mutually agreed upon. Upon such acceptance, as evidenced by signatures in the spaces provided below, this Bond Purchase Agreement

 SECTION 1.        DESCRIPTION OF SERIES 2007 BONDS. 

The Series 2007 Bonds will be issued pursuant to a Trust Indenture dated as of December 1,2006, (the “2006
Indenture”), from the Authority to U.S. Bank National Association, as trustee (the “Trustee”), as supplemented and amended by a First Supplemental Trust Indenture, dated as of November 1,2007 (the “First Supplement”
and, together with the 2006 Indenture, the 

  
 1 

 
“Indenture”) and are to be payable solely from the “Revenues” and the moneys available under the Indenture, being principally payments required to be made under a Loan
Agreement, dated as of December 1, 2006 (the “2006 Agreement”), by and among the Authority, the Trustee and the Company, as amended by a First Amendment to Loan Agreement, dated as of November 1, 2007 (the “First
Amendment” and, together with the 2006 Loan Agreement, the “Agreement”). To evidence its payment obligations under the Loan Agreement, the Company will execute and deliver its Series 2007 Project Note, dated as of Closing Date (as
herein defined) (the “Project Note”), to the Trustee. The Company’s obligations under the Loan Agreement and the Project Note are further secured by an Amended and Restated Security Agreement dated as of November 1, 2007 (the
“Security Agreement”) from the Company to the Trustee. In connection with the issuance of the Series 2007 Bonds, the Company will execute and deliver an Amended and Restated Intercreditor Agreement, to be dated the Closing Date, among the
Company, the Trustee and Wells Fargo Bank, N.A. (the “Bank”) in its capacity as “Lender” under that certain Amended and Restated Credit Agreement, dated as of December 9, 2005, between the Bank and the Company and other
affiliated entities, as supplemented and amended (the “Bank Credit Agreement”). 
 The Series 2007 Bonds are being
issued as “Additional Bonds” under the Indenture on a parity of lien with the $36,495,000 outstanding principal amount of Water and Wastewater Revenue Bonds (Global Water Resources, LLC Project), Series 2006 (the “Series 2006
Bonds” and, together with the Series 2007 Bonds, the “Bonds”), issued by the Authority under the 2006 Indenture. 

In the Loan Agreement, the Company agrees to make payments from, and in the Security Agreement, the Company assigns to the
Trustee for the payment of the Bonds, all of its rights to the “Income Available for Debt Service,” which constitutes all of the Company’s rights to receive the Palo Verde Receipts and the Santa Cruz Receipts (each as defined in the
Loan Agreement). 
 The proceeds of the sale of the Series 2007 Bonds will be loaned to the Company to reimburse the costs
of the acquisition, construction and equipping of water and wastewater treatment facilities to be owned and utilized by the Company or by Palo Verde or Santa Cruz (each as defined in the Loan Agreement and collectively, the “Project
Subsidiaries”), to fund the Bond Reserve Fund and to pay certain costs incurred in connection with the issuance of the Series 2007 Bonds. 

The Series 2007 Bonds will be dated, will be in an aggregate principal amount, will mature on December 1 in the years and
principal amounts, will bear interest at the rates and will be subject to optional, extraordinary and mandatory redemption, all as set forth in Exhibit A hereto and shall otherwise be as described in the Limited Offering Memorandum, dated the date
hereof (the “Limited Offering Memorandum”), as relating to the offering of the Series 2007 Bonds. 
 SECTION
2.        PURCHASE, SALE AND OFFERING OF THE SERIES 2007 BONDS. 
 Subject to
the terms and conditions and in reliance upon the representations, warranties and agreements set forth herein, the Purchaser hereby agrees to purchase from the Authority, and the Authority hereby agrees to sell and deliver to the Purchaser, all (but
not less than all) of the Series 2007 Bonds. The Authority’s obligation to issue the Series 2007 Bonds shall be conditioned on the 

  
 2 

 
understanding that all opinions and certificates under Section 7 hereof shall include the Authority as an addressee or expressly allow for reliance thereon by the Authority. 

The aggregate purchase price of the Series 2007 Bonds to be paid at the Closing shall be $52,812,150.00 (which represents the
aggregate principal amount of the Bonds of $54,135,000 less net original issue discount of $510,825.00 less Purchaser’s compensation of $812,025.00) (the “Purchase Price”). 

The Purchaser agrees to make a bona fide public offering of the Series 2007 Bonds at the offering prices or yields not in
excess of those set forth in Exhibit A hereto. The Purchaser may offer a portion of the Series 2007 Bonds for sale to selected dealers who are members of the National Association of Securities Dealers, Inc. and who agree to resell the Series 2007
Bonds to the public on terms consistent with this Bond Purchase Agreement. The Purchaser reserves, however, the right, in its sole discretion, to change such offering prices or yields as the Purchaser shall deem necessary in connection with the
offering of the Series 2007 Bonds and to offer and sell the Series 2007 Bonds to certain dealers (including the Purchaser and other dealers depositing the Series 2007 Bonds into investment trusts) and others at prices lower than the initial offering
prices or at yields higher than the initial yields set forth in the Limited Offering Memorandum (as such term is hereinafter defined). The Purchaser also reserves the right (a) to over allot or effect transactions that stabilize or maintain the
market price of the Series 2007 Bonds at a level above that which might otherwise prevail in the open market and (b) to discontinue such stabilizing, if commenced, at any time. A “bona fide public offering” shall include an offering
to a representative number of institutional investors or registered investment companies, regardless of the number of such investors to which the Series 2007 Bonds are sold. 

SECTION 3.        CLOSING. 

At 8:00 a.m., Mountain Standard Time, on November 28, 2007, or such other time or on such earlier or later date as the
Authority, the Company and the Purchaser mutually agree on (the “Closing Date” or “Closing”), the Authority will deliver the Series 2007 Bonds to the Purchaser in definitive typewritten form, duly executed and authenticated and
registered in the name of Cede & Co., as nominee of The Depository Trust Company (“DTC”), through the facilities of the DTC, and, upon receipt of the other documents hereinafter mentioned, the Purchaser will accept such delivery
and pay the purchase price of the Series 2007 Bonds as set forth in Section 2 hereof by a wire transfer of immediately available funds to the Trustee for the account of the Authority. Delivery and payment as aforesaid shall be made at the
office of Bond Counsel, Suite 300, 8601 North Scottsdale Road, Scottsdale, Arizona. 
 It is anticipated that CUSIP
identification numbers will be printed on the Series 2007 Bonds, but neither the failure to print such numbers on any Series 2007 Bond or any error with respect thereto shall constitute cause for a failure or refusal by the Purchaser to accept
delivery of the Series 2007 Bonds in accordance with the terms of this Bond Purchase Agreement. 
 The Series 2007 Bonds
will be made available to the Purchaser for checking and packaging as soon as practicable, but at least by 12:00 noon, on the business day prior to the Closing Date at the office of DTC or at such other place to which the parties hereto may agree
mutually.

 The Purchaser agrees to furnish to the Company and the Authority, prior to the
delivery of the Series 2007 Bonds, the initial offering prices of the Series 2007 Bonds to the public and such additional information and certificates as may be reasonably necessary to enable (i) the Authority to determine the “issue
price” of the Series 2007 Bonds for purposes of determining the yield on the Series 2007 Bonds within the meaning of Section 148 of the Internal Revenue Code of 1986, as amended (the “Code”), and (ii) Kutak Rock LLP, as Bond
Counsel, to determine the amount of original issue discount, if any, on the Series 2007 Bonds.

(ii) the Authority and the Company agree that (1) if any event relating to or which might affect the correctness or completeness of the Warranted Information contained in the Limited Offering Memorandum; (2) if any event shall occur
as a result of which the Warranted Information contained in the Limited Offering Memorandum as then amended or supplemented contains an untrue statement of a material fact or omits to state a material fact necessary in order to make such statements
therein, in the light of the circumstances when the Limited Offering Memorandum is delivered to a purchaser, not misleading or (3) if the Purchaser, the Authority or the Company is notified that such an event has occurred, then the Purchaser,
the Authority or the Company, as applicable (but, with respect to the Authority, only as the foregoing relates to the Authority Warranted Information), shall promptly notify the Purchaser, the Authority and the Company of the circumstances and
details of such event. If in the opinion of the Purchaser or the Authority it is necessary to amend or supplement the Limited Offering Memorandum to make the Limited Offering Memorandum not misleading in light of the circumstances existing at the
time it is delivered to a purchaser or potential customer (as defined for purposes of the Rule), the Authority and the Company will, at the request of the Purchaser or the Authority and at the expense of the Company, cooperate with and cause the
preparation of a reasonable number of copies of an amendment of or supplement to the Limited Offering Memorandum (in form and substance

a material fact necessary to make the statements therein, in light of the circumstances existing at the time the Limited Offering Memorandum is delivered to a purchaser or potential customer, not misleading; provided, however, that if such event
shall occur on or prior to the Closing Date, the Purchaser in its sole discretion shall have the right to terminate its obligations hereunder by written notice to the Authority and the Company and thereafter the Purchaser will be under no obligation
to purchase and pay for any of the Series 2007 Bonds. 
 The Authority and the Company agree, until the end of the Warranty
Period, (i) to notify the Purchaser, the Authority and the Company upon the occurrence of any material event adversely affecting the Authority or the Company, the properties or operations of the Authority or the Company or the consummation of

Offering Memorandum as required by this Section. 
 (e)        End of
Underwriting Period. Unless otherwise notified in writing by the Purchaser by the Closing Date, the Authority and the Company can assume that the “End of the Underwriting Period” for purposes of this Bond Purchase Agreement shall be
the Closing Date. In the event such notice is so given in writing by the Purchaser, the Purchaser agrees to notify the Authority and the Company in writing following the occurrence of the End of the Underwriting Period as defined in the Rule.

SECTION 9.        INDEMNIFICATION BY THE COMPANY. 

(a)        Scope of Indemnification. The Company will indemnify and hold
harmless the Authority, the County, the Purchaser, each director, trustee, partner, member, officer, official or employee or agent thereof and each person, if any, who controls the Purchaser within the meaning of the Securities Act (any such person
being herein sometimes called an “Indemnified Party”), for, from and against any and all losses, claims, damages or liabilities, joint or several, (i) to which any such Indemnified Party may become subject, under any statute or
regulation at law or in equity or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact set forth in the
Limited Offering Memorandum, or any amendment or supplement thereto, or the 

  
 18 

 
Preliminary Limited Offering Memorandum or arise out of or are based upon the omission or alleged omission to state in the Company Warranted Information therein a material fact required to be
stated therein or which is necessary to make the statements made therein, in light of the circumstances in which they were made, not misleading in any material respect; and (ii) to the extent of the aggregate amount paid in any settlement of
any litigation commenced or threatened arising from a claim based upon any such untrue statement or alleged untrue statement or omission or alleged omission if such settlement is effected with the written consent of the Company (which consent shall
not be unreasonably withheld); and will reimburse any legal or other expenses reasonably incurred by any such Indemnified Party in connection with investigating or defending any such loss, claim, damage, liability or action. 

(b)        Procedure. An Indemnified Party shall, promptly after the receipt of
notice of a written threat of the commencement of any action against such Indemnified Party in respect of which indemnification may be sought against the Company, notify the Company in writing of the commencement thereof. Failure of the Indemnified
Party to give such notice will reduce the liability of the Company by the amount of damages attributable to the failure of the Indemnified Parry to give such notice to the Company, but the omission to notify the Company of any such action shall not
relieve the Company from any liability that any of them may have to such Indemnified Party otherwise than under this Section. In case any such action shall be brought against an Indemnified Party and such Indemnified Party shall notify the Company
of the commencement thereof, the Company may, or if so requested. by such Indemnified Party shall, participate therein or assume the defenses thereof, with counsel satisfactory to such Indemnified Party and the Company (it being understood that,
except as hereinafter provided, the Company shall not be liable for the expenses of more than one counsel representing the Indemnified Parties in such action), and after notice from the Company to such Indemnified Party of an election so to assume
the defenses thereof, the Company will not be liable to such Indemnified Party under this Section for any legal or other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof other than reasonable costs of
investigation; provided, however, that unless and until the Company assumes the defense of any such action at the request of such Indemnified Party, the Company shall have the right to participate at its own expense in the defense of any such
action. If the Company shall not have employed counsel to have charge of the defense of any such action or if an Indemnified Party shall have reasonably concluded that there may be defenses available to it and/or other Indemnified Parties that are
different from or additional to those available to the Company (in which case the Company shall not have the right to direct the defense of such action on behalf of such Indemnified Party) or to other Indemnified Parties, legal and other expenses,
including the expense of separate counsel, incurred by such Indemnified Party shall be borne by the Company. 

(c)        Contribution. In order to provide for just and equitable
contribution in circumstances in which the indemnification provided for in this Section is applicable but for any reason is held to be unavailable to the Purchaser from the Company, the Company and the Purchaser shall contribute to the aggregate
losses, claims, damages and liabilities (including any investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claims asserted, but after deducting any
contribution received by the Company from persons who control the Company within the meaning of the Securities Act or otherwise) to which the Company and the Purchaser may be subject (i) in such proportion as shall be appropriate to reflect the
relative benefits received by the Company, on 

  
 19 

 
the one hand and the Purchaser on the other from the purchase of the Series 2007 Bonds or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Purchaser on the other with respect to the statements or omissions that
resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Purchaser, on the other, shall be deemed
to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Purchaser. The relative fault shall be determined
by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by or relating to the Company or the Purchaser, the intent of the parties and
their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Purchaser agree that it would not be just and equitable if contributions pursuant to this paragraph were to be
determined by pro rata allocation or by any other method of allocation that does not take into account the equitable consideration referred to herein. Notwithstanding the provisions hereof, the Purchaser shall not be required to contribute any
amount in excess of the amount by which the Purchaser’s compensation exceeds the amount of any damages the Purchaser has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission.
No person guilty of fraudulent misrepresentation shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this paragraph, each person, if any, who controls the Purchaser within the
meaning of the Securities Act shall have the same rights to contribution as the Purchaser and each person, if any, who. controls the Company within the meaning of the Securities Act shall have the same rights to contribution as the Company, subject
in each case to clauses (i) and (ii) of this paragraph. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for
contribution may be made against another party or parties under this paragraph, notify such party or parties from whom contribution may be sought, but the omission to so notify such party from whom contribution may be sought shall not relieve the
party or parties from whom contribution may be sought from any other obligation it or they may have hereunder or otherwise than under this Section. No party shall be liable for contribution with respect, to any action or claim settled without its
consent. 
 SECTION 10.        PAYMENT OF EXPENSES. 

The Purchaser shall be under no obligation to pay, and the Company shall pay or cause to be paid, any and all expenses and
costs incurred in connection with the authorization, issuance or sale of the Series 2007 Bonds, including, but not limited to: costs of preparing, printing and delivering the Preliminary Limited Offering Memorandum and the Final Limited Offering
Memorandum (including the word processing, duplicating and delivery charges incurred by Counsel to the Purchaser in connection with the preparation of preliminary or final drafts thereof); costs of printing, reproducing and binding the Financing
Documents and the Authority Documents; fees and expenses of the Trustee, Bond Counsel, the Auditor, Counsel to the Purchaser, Counsel to the Trustee and any paying agent or registrar; expenses in connection with the Closing; fees and expenses of
Counsel to the Authority and the fees and administrative expenses of the Authority; fees and expenses for preparation, printing, transportation and safekeeping of the Series 2007

 If optional redemption at a redemption price exceeding 100% of the principal
amount to be redeemed is to take place as of any applicable mandatory redemption date identified in the foregoing section hereof, the Series 2007 Bonds, or portions thereof, to be so redeemed shall be selected by lot prior to the selection by lot of
the Series 2007 Bonds to be redeemed on the same date by operation of mandatory provisions of the foregoing section of this Exhibit A. 
 Optional
Redemption 
 The Series 2007 Bonds maturing on December 1, 2013, are not subject to redemption prior to their
stated maturity date. The Series 2007 Bonds maturing on December 1, 2037, may be redeemed prior to maturity, in whole at any time, or in part by lot on any Interest Payment Date, by the Corporation, on or after December 1, 2017 at the
redemption price of the principal amount of the Series 2007 Bonds to be redeemed plus interest accrued to the date fixed for redemption. 
 Extraordinary
Optional Redemption 
 The Series 2007 Bonds are also subject to redemption by the Authority in the event of the
exercise by the Company of its option to direct redemption (i) at any time in whole, or (ii) on any Interest Payment Date in part in inverse order of maturity in the event of condemnation of part of the Project as described below, at a
redemption price of 100% of the principal amount of the Series 2007 Bonds redeemed, plus interest accrued to the redemption date, upon occurrence of any of the following events: 

(a)        The Project shall have been damaged or destroyed to such an extent that, in
the Company’s reasonable judgment, (1) it cannot reasonably be expected to be restored, within a period of six months, to the condition immediately preceding such damage or destruction, or (2) its normal use and operation is
reasonably expected to be prevented for a period of six consecutive months. 

(b)        Title to, or the temporary use of, all or a significant part of the Project
shall have been taken under the exercise of the power of eminent domain (1) to such extent that the Project cannot, in the Company’s reasonable judgment, reasonably be expected to be restored within a period of six months to a condition of
usefulness comparable to that existing prior to the taking, or (2) as a result of the taking, normal use and operation of the Project is reasonably expected, in the Company’s reasonable judgment, to be prevented for a period of six
consecutive months or more. 
 (c)        As a result of any changes in the
Constitution of the State, the Constitution of the United States of America, or state or federal laws or as a result of legislative or administrative action (whether state or federal) or by final decree, judgment or order of any court or
administrative body (whether state or federal) entered after the contest thereof by the Authority or the Company in good faith, the Loan Agreement shall have become void or unenforceable or impossible of performance in accordance with the intent and
purpose of the parties as expressed in the Loan Agreement, or if unreasonable burdens or excessive liabilities shall have been imposed with respect to the Project or the operation thereof, including, without limitation, federal, state or other ad
valorem, property, income or other taxes not being imposed on the date of the Loan Agreement other than ad valorem taxes presently levied upon privately owned property used for the same general purpose as the Project. 

  
 A-2 

 (d)        Changes in the economic
availability of raw materials, operating supplies, energy sources, labor, equipment or supplies, or facilities necessary for the efficient operation of the Project for the Project Purposes shall have occurred or technological or other changes shall
have occurred which the Company cannot reasonably overcome or control and which in the Company’s reasonable judgment render the Project uneconomic for the Project Purposes. 

(e)        A public offering with respect to the ownership interests in the Company.

 To exercise the Company’s option to redeem Series 2007 Bonds following the occurrence of one of the event listed in
(a) through (d) above, the Company shall give notice to the Authority and to the Trustee specifying the date on which the Company will deliver the funds required for that redemption, which date shall be not more than 90 days from the date
that notice is mailed and shall make arrangements satisfactory to the Trustee for the giving of the required notice of redemption. 

To exercise the Company’s option to redeem Series 2007 Bonds following the occurrence of one of the events listed in
(e) above, the Company shall give notice to the Authority and to the Trustee specifying the date on which the Company will deliver the funds required for that redemption, which date shall be not more than 90 days from the date that the event
described in (e) occurred and shall make arrangements satisfactory to the Trustee for the giving of the required notice of redemption. 

The Company also shall have the option, in the event that title to or the temporary use of a portion of the Project shall be
taken under the exercise of the power of eminent domain, even if the taking is not of such nature as to permit the exercise of the redemption option upon an event specified in (b) above, to direct the redemption, at a redemption price of 100%
of the principal amount of Series 2007 Bonds prepaid, plus accrued interest to the redemption date, of that part of the outstanding principal balance of the Series 2007 Bonds as may be payable from the proceeds (after the payment of costs and
expenses incurred in the collection thereof) received in the eminent domain proceeding, provided, that, the Company shall furnish to the Authority and the Trustee a certificate of a duly qualified independent engineer stating that (1) the
property comprising the part of the Project taken is not essential to continued operations of the Project in the manner existing prior to that taking, (2) the Project has been restored to a condition substantially equivalent to that existing
prior to the taking, or (3) other improvements have been acquired or made which are suitable for the continued operation of the Project. 

Mandatory Redemption Upon a Determination of Taxability 

The Company will be obligated to redeem all outstanding Series 2007 Bonds, within 180 days after the Trustee receives
notification that a “Determination of Taxability” (as defined in the Trust Agreement) has occurred, at 103% of the principal amount of the Series 2007 Bonds outstanding at the time of a Determination of Taxability plus accrued interest to
the redemption date.

FORM OF OPINION OF COUNSEL TO THE AUTHORITY 

[Letterhead of Russo, Russo & Slania] 

November 28, 2007 
 THE INDUSTRIAL
DEVELOPMENT AUTHORITY 
     OF THE COUNTY OF PIMA 

Tucson, Arizona 
  

			
	 Re:
	  	 The Industrial Development Authority of the County of Pima, Water and

Wastewater Revenue Bonds (Global Water Resources LLC Project),

Series 2007

 Ladies and Gentlemen: 

We have acted as counsel to The Industrial Development Authority of the County of Pima (the “Authority”) in
connection with the issuance and delivery of the above-captioned bonds (the “Bonds”). The Bonds are being issued pursuant to a Trust Indenture, dated as of December 1, 2006 (the “2006 Indenture”), between the Authority and
U.S. Bank National Association (the “Trustee”), as supplemented by a First Supplemental Trust Indenture, dated as of November 1, 2007 (the “First Supplement” and, together with the 2006 Indenture, the “Indenture”),
and are being sold pursuant to the Bond Purchase Agreement dated November 19, 2007 (the “Bond Purchase Agreement”), executed by the Authority, Global Water Resources LLC, a Delaware limited liability company (the “Borrower”)
and Hutchinson, Shockey, Erley & Co. (the “Underwriter”). Capitalized terms used, and not otherwise defined, herein shall have the meanings set forth in the Indenture. 

We are members of the Arizona Bar and serve as general counsel to the Authority. In connection with the issuance on this date
by the Authority of its Bonds, we have examined, among other things, the following: 
  

	 	A.	 Executed counterparts of the Indenture, the Loan Agreement dated as of December 1, 2006, among the Authority, the Trustee and the Borrower
(the “2006 Loan Agreement”), as amended by a First Amendment to Loan Agreement, dated as of November 1, 2007 (the “First Amendment” and, together with the 2006 Loan Agreement, the “Loan Agreement”), the Bond
Purchase Agreement, the Tax Certificate dated the date hereof and various other documents or certificates executed by the Authority in connection with the issuance, sale and delivery of the Bonds (collectively referred to as the “Authority
Documents”); 

  

	 	B.	 The provisions of Title 35, Chapter 5, Arizona Revised Statutes, as amended and supplemented (collectively, the “Act”);

  
 B-1 

	 	C.	 The Articles of Incorporation of the Authority (the “Articles”) and the Bylaws of the Authority (the “Bylaws”);

  

	 	D.	 A copy of the proceedings of record of the Board of Directors of the Authority, including the resolution adopted on September 17, 2007 (the
“Authority Resolution”), in connection with the authorization, issuance, sale and delivery of the Bonds and the Authority Documents; 

  

	 	E.	 A copy of the Limited Offering Memorandum regarding the Bonds (the “Limited Offering Memorandum”); and 

 

	 	F.	 Such other laws, matters and documents as we deem necessary for purposes of this opinion. 

As to questions of fact material to our opinion, we have relied upon the representations of the Authority contained in the
Authority Documents, the Authority Resolution and other certifications of public officials furnished to us without undertaking to verify the same by independent investigation. We have also assumed (i) the genuineness of the signatures not
witnessed, the authenticity of documents submitted as originals, and the conformity to originals of documents submitted as copies, (ii) the legal capacity of all natural persons executing the Authority Documents and (iii) that the
Authority Documents accurately describe and contain the mutual understanding of the parties, and that there are not oral or written statements or agreements that modify, amend, or vary, or purport to modify, amend, or vary, any of the terms of the
Authority Documents. 
 Based upon the foregoing and upon such other information and documents as we believe necessary to
enable us to render this opinion, we are of the opinion that: 
 1.         The
Authority is a duly organized nonprofit corporation designated as a political subdivision under the laws of the State of Arizona, with the requisite corporate power and corporate authority to issue the Bonds, to execute and deliver the Authority
Documents and to carry out and perform its obligations under the Authority Resolution and the Authority Documents. 

2.         The execution and delivery of the Bonds, the Authority Resolution and the
Authority Documents by the Authority have been duly authorized by the Authority and have been duly executed and delivered by the Authority and approved by the Board of Supervisors of Pima County, Arizona. The Authority Resolution has been duly
passed by the Authority, is in full force and effect and has not been repealed by the Authority. 

3.         To the best of our knowledge, no action, suit, proceedings, inquiry at law
or in equity are pending or threatened in any way affecting the existence of the Authority or the titles of its officers to their respective offices, or seeking to restrain or to enjoin the issuance, sale or delivery of the Bonds, or the collection
or application of revenues of the Authority pledged or to be pledged to pay the principal of and interest on the Bonds, or the pledge thereof, or in any way contesting or affecting the validity or enforceability of the Bonds or the powers of the
Authority or its authority with respect to the Bonds. 

  
 B-2 

 4.        The execution and delivery of
any of the Authority Documents and compliance with the provisions thereof, under the circumstances contemplated thereby, (i) do not violate the Act, the Articles, the Bylaws or any law, ordinance, administrative regulation, judgment,
injunction, decree, determination or award, currently in effect of which we have knowledge to which the Authority is subject and (ii) do not and will not in any material respect conflict with or constitute on the part of the Authority a breach
of or default under any indenture, deed of trust, mortgage, agreement, or other instrument of which we have knowledge and to which the Authority is a party. 

5.        Other than the approval of the Pima County, Arizona Board of Supervisors
(which has been obtained), no further consents or approvals are necessary from the Authority for the issuance of the Bonds or the valid execution, delivery or performance of the Authority Documents. The Authority has duly authorized the use of the
Limited Offering Memorandum. 
 6.        Without having undertaken to determine
independently the accuracy or completeness of the statements contained in the Limited Offering Memorandum therein under the captions “THE AUTHORITY” or “ABSENCE OF LITIGATION” as it relates to the Authority, nothing has come to
our attention which would lead us to believe that that portions of the Limited Offering Memorandum under the captions “THE AUTHORITY” or “ABSENCE OF LITIGATION” as it relates to the Authority contains an untrue statement of a
material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. 

As counsel for the Authority, we are passing only upon those matters set forth in this opinion and are not passing upon the
accuracy or completeness of any statements made in connection with any offering or sale of the Bonds, except as otherwise specifically set forth herein. 

By letter dated
                        , 2007 to the Attorney General of the State of Arizona (the “Attorney General”), the
Authority notified the Attorney General, as required by A.R.S. Section 35-721 (F), of its intention to issue the Bonds. The Attorney General acknowledged receipt of such notice in a letter dated
                , 2007. As of the date hereof, the Authority has not received any notice from the Attorney General to the effect that, in his opinion, the Project
does not come within the purview of the Act. 
 No other person, other than the addressees, may rely upon this opinion
without written consent. 
  

			
	Respectfully submitted,

$54,135,000 Water and Wastewater Revenue Bonds (Global Water Resources LLC Project),
Series 2007

 Ladies and Gentlemen: 

We have acted as counsel for Global Water Resources LLC, a Delaware limited liability company authorized to conduct business
in the State of Arizona (the “Borrower”) in matters related to the issuance by The Industrial Development Authority of the County of Pima (the “Authority”) of $54,135,000 aggregate principal amount of its Water and Wastewater
Revenue Bonds (Global Water Resources LLC Project), Series 2007, dated this date (the “Bonds”). Words and terms used in this opinion letter and not otherwise defined herein are intended to have the meanings assigned to them in the Bond
Purchase Agreement, dated November 19, 2007 (the “Bond Purchase Agreement”), among the Borrower, the Authority and Hutchinson, Shockey, Erley & Co., as underwriter of the Bonds (the “Underwriter”). This letter is
delivered as an opinion of counsel to the Borrower contemplated by Section 7(d)(3) of the Bond Purchase Agreement. 

In connection with our representation of the Borrower, we have examined the law and such documents and matters as we have
deemed necessary to render the opinions expressed in this letter, including, without limitation, originals or copies of: 

(a)        The Loan Agreement, dated as of December 1, 2006 (the “2006 Loan
Agreement”), among the Authority, the Trustee and the Borrower, as amended by a First Amendment to Loan Agreement, dated as of November 1, 2007 (the “First Amendment” and, together with the 2006 Loan Agreement, the “Loan
Agreement”). 

  
 C-1 - page 1 

 (b)        The Series 2007 Project Note
of the Borrower, dated this date (the “Project Note”) executed and delivered to evidence the Borrower’s obligations under the Loan Agreement. 

(c)        The Trust Indenture, dated as of December 1, 2006 (the “2006
Indenture”), between the Authority and U.S. Bank National Association, as Bond Trustee (the “Trustee”), as supplemented by a First Supplement to Trust Indenture, dated as of November 1, 2007 (the “First Supplement” and,
together with the 2006 Indenture, the “Indenture”). 
 (d)        The
Amended and Restated Security Agreement, dated as of November 1, 2007 (the “Security Agreement”), between the Borrower and the Trustee. 

(e)        The Amended and Restated Intercreditor Agreement, dated November 28,
2007 (the “Intercreditor Agreement”), among the Borrower, the Trustee and Wells Fargo Bank, N.A., as lender under the Credit Facility Agreement (as defined in the Intercreditor Agreement). 

(f)        The Bond Purchase Agreement. 

(g)        The Tax Exemption Certificate and Agreement, of even date herewith (the
“Tax Regulatory Agreement”); 
 (h)        The Continuing Disclosure
Undertaking, dated this date (the “Continuing Disclosure Agreement”), between the Borrower and the Bond Trustee. 

(i)        The Limited Offering Memorandum, dated November 19, 2007 (the
“Limited Offering Memorandum”) with respect to the Bonds. 

(j)        Such corporate documents and records of the Borrower, certificates of
public officials and officers of the Borrower and such other documents as we have deemed necessary or appropriate for the purposes of the opinions expressed in this letter. 

The Loan Agreement, the Project Note, the Security Agreement, the Tax Regulatory Agreement, the Bond Purchase Agreement, the
Intercreditor Agreement and the Continuing Disclosure Agreement are referred to herein collectively as the “Bond Issue Agreements.” The Bond Issue Agreements and the Indenture are referred to herein collectively as the
“Agreements.” 
 In connection with our examination, we have relied upon and assumed compliance with the
provisions of the documents examined, and we have assumed the accuracy and completeness of the statements, certificates, and representations furnished to us without undertaking to verify the same by independent investigation. We have assumed, and
have not verified, (i) the genuineness of the signatures on all documents, the authenticity of documents submitted as originals, and the conformity to originals of documents submitted as copies; (ii) the legal capacity of all individuals
executing the documents; (iii) that the documents accurately describe the mutual understanding of the parties thereof, and that there are no oral or written statements that modify, amend, or vary, or purport to modify, amend, or vary, any of
the terms of the documents; (iv) that the Borrower own all of the property, assets, and rights purported to be owned by them; and (v) that no interest, charges, fees, or other benefits or compensation in the nature of interest in
connection with the transactions contemplated by the documents will be received other than those that the Borrower has agreed in writing in the Agreements to pay. As to matters noted below, we have also relied

  
 C-1 - page 2 

 
upon that certain opinion of Roshka DeWulf & Patten, PLC dated this date (attached hereto as Exhibit A). We have further relied on the Borrower’s Certificate dated this date
(attached hereto as Exhibit B). 
 Based upon the foregoing, we are of the opinion, and we herewith advise you, as follows:

 1.        The Borrower is limited liability company duly organized, validly
existing, and in good standing under the laws of the State of Delaware, duly authorized to do business in the State of Arizona, with full legal right, power and authority to execute, deliver, and perform its obligations under the Agreements to which
it is a party. 
 2.        Each of the Bond Issue Agreements have been duly
authorized, executed and delivered on behalf of Borrower and are valid and binding obligations of Borrower enforceable against Borrower in accordance with their respective terms, except as enforceability may be limited by bankruptcy, insolvency,
reorganization, or other similar laws or equitable principles affecting the enforcement of creditors’ rights generally, and except as the enforceability of the indemnifications set forth in the Bond Purchase Agreement may be limited by
principles of public policy. 
 3.        The execution and delivery of the each of
the Bond Issue Agreements by the Borrower, and the approval by the Borrower of the Bond Indenture, the Bonds and the Limited Offering Memorandum, and compliance by the Borrower with the provisions of the Bond Issue Agreements, do not and will not
conflict with or constitute a breach of or a default under the provisions of the Articles of Organization or Operating Agreement of the Borrower, and upon execution and delivery of the Intercreditor Agreement do not and will not in any material
respect constitute on the part of the Borrower a breach of or default under any material indenture, deed of trust, mortgage, agreement, or other instrument of which the participating attorneys in our firm have knowledge and to which the Borrower is
a party or by which the Borrower or its properties is bound, and, to the actual knowledge of the participating attorneys in our firm, do not materially conflict with, violate, or result in a breach of any existing law, public administrative rule or

FORM OF OPINION OF LENDER’S COUNSEL 

[Letterhead of Wells Fargo Bank, National Association] 

November 28, 2007 
 To Each of the
Addressees Listed in Schedule A Attached Hereto 
 Ladies and Gentlemen: 

I have acted as counsel to Wells Fargo Bank, National Association, a national banking association (“Wells Fargo”) in
connection with that certain Amended and Restated Intercreditor Agreement dated as of November 28,2007 (the “Agreement”), by and between Wells Fargo and U.S. Bank National Association, as trustee (“Creditor”). Capitalized
terms used herein without definition are used as defined in the Agreement. 
 In connection with my opinions expressed
below, I have examined an executed copy of the Agreement and I have also examined originals, or copies certified to my satisfaction, of such other documents, certificates of public officials, corporate records and other instruments as I have deemed
relevant and necessary as a basis for the opinions expressed below. In such examination, I have assumed the genuineness of all signatures and the authenticity of all documents submitted to me as originals and the conformity with the originals of all
documents submitted to me as copies. I have relied upon originals or copies, certified or otherwise identified to my satisfaction, of such other documents as I have deemed relevant to the rendering of this opinion. I have also relied, without any
independent investigation or verification of any kind, on the representations and warranties contained in each of the Documents with respect to the accuracy of material factual matters contained therein which were not independently established. 

Based on the foregoing, I am of the following opinion: 

1.        Wells Fargo is a national banking organization duly organized and validly
existing under United States federal law and has the power and authority to enter into the Agreement and to consummate the transactions contemplated thereby. 

2.        The execution, delivery and performance of the Agreement has been duly
authorized by all necessary corporate action on the part of Wells Fargo and does not conflict with any of the organizational or governance documents of Wells Fargo. 

3.        The Agreement has been duly executed and delivered by Wells Fargo. 

4.        The Agreement constitutes the legal, valid and binding obligation of Wells
Fargo enforceable against Wells Fargo in accordance with the terms thereof, except as the enforceability thereof may be limited by (a) general equitable principles (regardless of whether such enforceability is considered in a proceeding in
equity or at law) and (b) applicable 

  
 H-1 

 bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the rights of creditors generally.

 No one other than you is entitled to rely on the opinions expressed herein. This opinion is not intended to be used in
any transaction other than the one described above. It is being delivered to you with the understanding that neither it nor its contents may be published, communicated or otherwise made available, in whole or in part, to any other person or entity
without, in each instance, my specific prior written consent. I do not undertake to advise you of any change in the matters covered by this opinion after the date hereof. 

Very truly yours,
