Section    Heading    Page

This Guaranty Agreement, dated as of January 3, 2024 (this “Guaranty Agreement”), is made by West Maricopa Combine, LLC, an Arizona limited liability company (the “Guarantor”) in favor of the Purchasers (as defined below) and the other holders from time to time of the Notes (as defined below). The Purchasers and such other holders from time to time of the Notes are herein collectively called the “holders” and individually a “holder.”

    I.    Global Water Resources, Inc., a Delaware corporation (the “Company”), entered into a Note Purchase Agreement dated as of October 26, 2023 (as amended, modified, supplemented or restated from time to time, the “Note Agreement”) with the Persons listed on the signature pages thereto (the “Purchasers”). Capitalized terms used herein have the meanings specified in the Note Agreement unless otherwise defined herein.

    II.    The Company, the purchasers of the notes issued pursuant to the 2016 Note Purchase Agreement, and U.S. Bank National Association, in its capacity as collateral agent for the benefit of the Secured Parties (as defined therein) (the “Collateral Agent”) entered into a Third Amended and Restated Collateral Agency Agreement dated as of October 26, 2023 (as amended, modified, supplemented or restated from time to time, the “Collateral Agreement”). On or about the date hereof, the Purchasers have executed and delivered a Joinder Agreement, pursuant to which the Purchasers have become parties to the Collateral Agreement and “Secured Parties” thereunder, all as more particularly provided in such Joinder Agreement.

    III.    The Company has authorized the issuance, pursuant to the Note Agreement, of 6.91% Senior Secured Notes due January 3, 2034 in the aggregate principal amount of $20,000,000. Pursuant to the Note Agreement, the Company proposes to issue and sell $20,000,000 aggregate principal amount of its 6.91% Senior Secured Notes due January 3, 2034 (the “Initial Notes”). The Initial Notes and any other Notes that may from time to time be issued pursuant to the Note Agreement (including any notes issued in substitution for any of the Notes) are herein collectively called the “Notes” and individually a “Note”.

    IV.    Pursuant to the Note Agreement, the Company is required to cause the Guarantor to deliver this Guaranty Agreement to the holders.

    V.    The Guarantor will receive direct and indirect benefits from the financing arrangements contemplated by the Note Agreement. The Board of Directors of the Guarantor has determined that the incurrence of such obligations is in the best interests of the Guarantor.

Now Therefore, in compliance with the Note Agreement, and in consideration of, the execution and delivery of the Note Agreement and the purchase of the Notes by each of the Purchasers, the Guarantor hereby covenants and agrees with, and represents and warrants to each of the holders as follows:

The Guarantor hereby irrevocably and unconditionally guarantees to each holder, the due and punctual payment in full of (a) the principal of, Make-Whole Amount, if any, and interest on (including, without limitation, interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding, whether or not a claim for post-filing or post-petition interest is allowed in such proceeding), and any other amounts due under, the Notes when and as the same shall become due and payable (whether at stated maturity or by required or optional prepayment or by acceleration or otherwise) and (b) any expenses, indemnities and other sums which may become due to the holders or the Collateral Agent under the terms and provisions of the Notes, the Note Agreement, the Collateral Agreement or any other Note Document (all such obligations described in clauses (a) and (b) above are herein called the “Guaranteed Obligations”).

The guaranty in the preceding sentence is an absolute, present and continuing guaranty of payment and not of collectability and is in no way conditional or contingent upon any attempt to collect from the Company or any other guarantor of the Notes or other Guaranteed Obligations or upon any other action, occurrence or circumstance whatsoever. In the event that the Company shall fail to pay any of such Guaranteed Obligations, the Guarantor agrees to pay the same when due to the Collateral Agent and/or holders entitled thereto, without demand, presentment, protest or notice of any kind, in lawful money of the United States of America, pursuant to the requirements for payment specified in the Notes, the Note Agreement, the Collateral Agreement and the other Note Documents. Each default in payment of any of the Guaranteed Obligations shall give rise to a separate cause of action hereunder and separate suits may be brought hereunder as each cause of action arises. The Guarantor agrees that the Notes issued pursuant to the Note Agreement may (but need not) make reference to this Guaranty Agreement.

The Guarantor hereby acknowledges and agrees that the Guarantor’s liability hereunder is joint and several with any other Person(s) who may guarantee the Guaranteed Obligations.

Notwithstanding the foregoing provisions or any other provision of this Guaranty Agreement, by their acceptance of this Guaranty, the Purchasers (on behalf of themselves and their successors and assigns) and the Guarantor hereby agree that if at any time the Guaranteed Obligations exceed the Maximum Guaranteed Amount determined as of such time with regard to the Guarantor, then this Guaranty Agreement shall be automatically amended to reduce the Guaranteed Obligations to the Maximum Guaranteed Amount. Such amendment shall not require the written consent of the Guarantor or any holder and shall be deemed to have been automatically consented to by the Guarantor and each holder. The Guarantor agrees that the Guaranteed Obligations may at any time exceed the Maximum Guaranteed Amount without affecting or impairing the obligation of the Guarantor. “Maximum Guaranteed Amount” means as of the date of determination with respect to the Guarantor, the lesser of (a) the amount of the Guaranteed Obligations outstanding on such date and (b) the maximum amount that would not render the Guarantor’s liability under this Guaranty Agreement subject to avoidance under Section 548 of the United States Bankruptcy Code (or any successor provision) or any comparable provision of applicable state law.

The obligations of the Guarantor hereunder shall be primary, absolute, irrevocable and unconditional, irrespective of the validity or enforceability of the Notes, the Note Agreement, the Collateral Agreement or any other Note Document, shall not be subject to any counterclaim, setoff, deduction or defense based upon any claim the Guarantor may have against the Company or any holder or otherwise, and shall remain in full force and effect without regard to, and shall not be released, discharged or in any way affected by, any circumstance or condition whatsoever (whether or not the Guarantor shall have any knowledge or notice thereof), including, without limitation: (a) any amendment to, modification of, supplement to or restatement of the Notes, the Note Agreement or any other Note Document (it being agreed that the obligations of the Guarantor hereunder shall apply to the Notes, the Note Agreement or any other Note Document as so amended, modified, supplemented or restated) or any assignment or transfer of any thereof or of any interest therein, or any furnishing, acceptance or release of any security for the Notes; (b) any waiver, consent, extension, indulgence or other action or inaction under or in respect of the Notes, the Note Agreement, the Collateral Agreement or any other Note Document; (c) any bankruptcy, insolvency, arrangement, reorganization, readjustment, composition, liquidation or similar proceeding with respect to the Company or its property; (d) any merger, amalgamation or consolidation of the Guarantor or of the Company into or with any other Person or any sale, lease or transfer of any or all of the assets of the Guarantor or of the Company to any Person; (e) any failure on the part of the Company for any reason to comply with or perform any of the terms of any other agreement with the Guarantor; (f) any failure on the part of the Collateral Agent or any holder to obtain, maintain, register or otherwise perfect any security; or (g) any other event or circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor (whether or not similar to the foregoing), and in any event however material or prejudicial it may be to the Guarantor or to any subrogation, contribution or reimbursement rights the Guarantor may otherwise have.

The Guarantor unconditionally waives to the fullest extent permitted by law, (a) notice of acceptance hereof, of any action taken or omitted in reliance hereon and of any default by the Company in the payment of any amounts due under the Notes, the Note Agreement, the Collateral Agreement or any other Note Document, and of any of the matters referred to in Section 2 hereof, (b) all notices which may be required by statute, rule of law or otherwise to preserve any of the rights of the Collateral Agent or any holder against the Guarantor, including, without limitation, presentment to or demand for payment from the Company or the Guarantor with respect to any Note, notice to the Company or to the Guarantor of default or protest for nonpayment or dishonor and the filing of claims with a court in the event of the bankruptcy of the Company, (c) any right to require the Collateral Agent or any holder to enforce, assert or exercise any right, power or remedy including, without limitation, any right, power or remedy conferred in the Note Agreement, the Notes, the Collateral Agreement or any other Note Document, (d) any requirement for diligence on the part of the Collateral Agent or any holder and (e) any other act or omission or thing or delay in doing any other act or thing which might in any manner or to any extent vary the risk of the Guarantor or otherwise operate as a discharge of the Guarantor or in any manner lessen the obligations of the Guarantor hereunder.

The Guarantor authorizes the Collateral Agent and/or the holders (as applicable), without notice or demand to the Guarantor and without affecting its obligations hereunder, from time to time: (a) to renew, compromise, extend, accelerate or otherwise change the time for payment of, all or any part of the Notes, the Note Agreement, the Collateral Agreement or any other Note Document; (b) to change any of the representations, covenants, events of default or any other terms or conditions of or pertaining to the Notes, the Note Agreement, the Collateral Agreement or any other Note Document, including, without limitation, decreases or increases in amounts of principal, rates of interest, the Make-Whole Amount or any other obligation; (c) to take and hold security for the payment of the Notes, the Note Agreement, this Guaranty Agreement or any other Note Document, for the performance of this Guaranty Agreement or otherwise for the Indebtedness guaranteed hereby and to exchange, enforce, waive, subordinate and release any such security; (d) to apply any such security and to direct the order or manner of sale thereof as the Collateral Agent (in accordance with the Collateral Agreement) or the holders in their sole discretion may determine; (e) to obtain additional or substitute endorsers or guarantors; (f) to exercise or refrain from exercising any rights against the Company and others (including other guarantors); and (g) to apply any sums, by whomsoever paid or however realized, to the payment of the Guaranteed Obligations and all other obligations owed hereunder. Neither the holders nor the Collateral Agent shall have any obligation to proceed against any additional or substitute endorsers or guarantors or to pursue or exhaust any security provided by the Company, the Guarantor any other guarantor or any other Person or to pursue any other remedy available to the Collateral Agent or the holders.

If an event permitting the acceleration of the maturity of the principal amount of any Notes shall exist and such acceleration shall at such time be prevented or the right of any holder to receive any payment on account of the Guaranteed Obligations shall at such time be delayed or otherwise affected by reason of the pendency against the Company, the Guarantor or any other guarantor of a case or proceeding under a bankruptcy or insolvency law, the Guarantor agrees that, for purposes of this Guaranty Agreement and its obligations hereunder, the maturity of such principal amount shall be deemed to have been accelerated with the same effect as if the holder thereof had accelerated the same in accordance with the terms of the Note Agreement, and the Guarantor shall forthwith pay such accelerated Guaranteed Obligations.

    (a)    The Guarantor will not exercise any rights which it may have acquired by way of subrogation under this Guaranty Agreement, by any payment made hereunder or otherwise, or accept any payment on account of such subrogation rights, or any rights of reimbursement, contribution or indemnity or any rights or recourse to any security for the Notes or this Guaranty Agreement unless and until all of the Guaranteed Obligations shall have been indefeasibly paid in full in cash.

    (b)    The Guarantor hereby subordinates the payment of all Indebtedness and other obligations of the Company or any other guarantor of the Guaranteed Obligations owing to the Guarantor, whether now existing or hereafter arising, including, without limitation, all rights and

claims described in clause (a) of this Section 5, to the indefeasible payment in full in cash of all of the Guaranteed Obligations. Subject to the Collateral Agreement, if the Collateral Agent or the Required Holders so request, any such Indebtedness or other obligations shall be enforced and performance received by the Guarantor as trustee for the holders and the proceeds thereof shall be paid over to the holders promptly, in the form received (together with any necessary endorsements) to be applied to the Guaranteed Obligations, whether matured or unmatured, as may be directed by the Required Holders, but without reducing or affecting in any manner the liability of the Guarantor under this Guaranty Agreement.

    (c)    If any amount or other payment is made to or accepted by the Guarantor in violation of any of the preceding clauses (a) and (b) of this Section 5, such amount shall be deemed to have been paid to the Guarantor for the benefit of, and held in trust for the benefit of, the holders and shall be paid over to the holders promptly (or as otherwise provided in Section 5(b)), in the form received (together with any necessary endorsements) to be applied to the Guaranteed Obligations, whether matured or unmatured, as may be directed by the Required Holders (or as otherwise provided in Section 5(b)), but without reducing or affecting in any manner the liability of the Guarantor under this Guaranty Agreement.

    (d)    The Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Note Agreement and that its agreements set forth in this Guaranty Agreement (including this Section 5) are knowingly made in contemplation of such benefits.

This Guaranty Agreement shall continue to be effective, or be reinstated, as the case may be, if and to the extent at any time payment, in whole or in part, of any of the sums due to any holder on account of the Guaranteed Obligations is rescinded or must otherwise be restored or returned by a holder upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company or any other guarantor, or upon or as a result of the appointment of a custodian, receiver, trustee or other officer with similar powers with respect to the Company or any other guarantor or any part of its or their property, or otherwise, all as though such payments had not been made.

The Guarantor will ensure that its payment obligations under this Guaranty Agreement will at all times rank at least pari passu, without preference or priority, with all other unsecured and unsubordinated Indebtedness of the Guarantor now or hereafter existing.

This Guaranty Agreement and all guarantees, covenants and agreements of the Guarantor contained herein shall continue in full force and effect and shall not be discharged until such time

as all of the Guaranteed Obligations and all other obligations hereunder shall be indefeasibly paid in full in cash and shall be subject to reinstatement pursuant to Section 6.

All representations and warranties contained herein shall survive the execution and delivery of this Guaranty Agreement and may be relied upon by any subsequent holder, regardless of any investigation made at any time by or on behalf of any Purchaser or any other holder. All statements contained in any certificate or other instrument delivered by or on behalf of the Guarantor pursuant to this Guaranty Agreement shall be deemed representations and warranties of the Guarantor under this Guaranty Agreement. Subject to the preceding sentence, this Guaranty Agreement embodies the entire agreement and understanding between each holder and the Guarantor and supersedes all prior agreements and understandings relating to the subject matter hereof.

    Section 10.1.    Requirements. Except as otherwise provided in the fourth paragraph of Section 1 of this Guaranty Agreement, this Guaranty Agreement may be amended, and the observance of any term hereof may be waived (either retroactively or prospectively), with (and only with) the written consent of the Guarantor and the Required Holders, except that no amendment or waiver (a) of any of the first three paragraphs of Section 1 or any of the provisions of Section 2, 3, 4, 5, 6, 7, 8, or 12 hereof, or any defined term (as it is used therein), or (b) which results in the limitation of the liability of the Guarantor hereunder (except to the extent provided in the fourth paragraph of Section 1 of this Guaranty Agreement) will be effective as to any holder unless consented to by such holder in writing.

    (a)    Solicitation. The Guarantor will provide each holder of the Notes (irrespective of the amount of Notes then owned by it) with sufficient information, sufficiently far in advance of the date a decision is required, to enable such holder to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the provisions hereof. The Guarantor will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 10.2 to each holder promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite holders of Notes.

    (b)    Payment. The Guarantor will not directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant any security or provide other credit support, to any holder as consideration for or as an inducement to the entering into by any holder of any waiver or amendment of any of the terms and provisions hereof unless such remuneration is concurrently paid, or security is concurrently granted or other credit support concurrently provided, on the same terms, ratably to each holder even if such holder did not consent to such waiver or amendment.

    (c)    Consent in Contemplation of Transfer. Any consent made pursuant to this Section 10 by a holder that has transferred or has agreed to transfer its Notes to the Company, or to any Subsidiary or any Affiliate (including the Guarantor) of the Company, and has provided or has agreed to provide such written consent as a condition to such transfer, shall be void and of no force or effect except solely as to such holder, and any amendments effected or waivers granted or to be effected or granted that would not have been or would not be so effected or granted but for such consent (and the consents of all other holders of Notes that were acquired under the same or similar conditions) shall be void and of no force or effect except solely as to such holder.

    Section 10.3.    Binding Effect. Any amendment or waiver consented to as provided in this Section 10 applies equally to all holders and is binding upon them and upon each future holder and upon the Guarantor without regard to whether any Note has been marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any obligation, covenant or agreement not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Guarantor and the holder nor any delay in exercising any rights hereunder or under any Note shall operate as a waiver of any rights of any holder.

    Section 10.4.    Notes held by Guarantor, Company, Etc.
