Unless otherwise specified herein, capitalized terms used in this Amendment shall have the meanings ascribed to them in the Amended Credit Agreement (as hereinafter defined) as amended hereby.

A.WHEREAS, the Borrower, the Lenders and the Administrative Agent are parties to that certain Credit Agreement dated as of August 2, 2022 (as amended, restated, supplemented or otherwise modified prior to the date hereof, the “Existing Credit Agreement”, and as amended by this Amendment, the “Amended Credit Agreement”);

B.WHEREAS, each Borrower has requested that the Lenders and the Administrative Agent agree to extend the Maturity Date and to make certain other amendments to the Existing Credit Agreement; and

C.WHEREAS, subject to the terms and conditions set forth herein, the Administrative Agent and the Lenders have agreed to extend the Maturity Date with respect to their Commitments and to amend the Existing Credit Agreement as set forth herein.

NOW, THEREFORE, for and in consideration of the premises and mutual agreements herein contained and for the purposes of setting forth the terms and conditions of this Amendment and for other valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be bound, hereby agree as follows:

1.Amendments to Existing Credit Agreement. Effective as of the Second Amendment Effective Date but subject to the satisfaction of the conditions precedent set forth in Section 2 below, the parties hereto agree that the Existing Credit Agreement is amended as follows:

(a)    The definition of “Maturity Date” appearing in Section 1.01 of the Existing Credit Agreement is amended to delete the reference to “August 2, 2028” appearing therein and to replace such reference with “August 2, 2029”.

(b)    Section 1.01 of the Existing Credit Agreement is amended to add the following defined term thereto in the appropriate alphabetic order:

“Second Amendment Effective Date” means August 2, 2024.

(c)    Section 2.21(a) of the Existing Credit Agreement is amended and restated in its entirety as follows:

(a) The Borrowers may, by delivering an Extension Request to the Administrative Agent (who shall promptly deliver a copy to each of the Lenders), not less than 45 days in advance of the Maturity Date in effect at such time (the “Existing Maturity Date”), request that the Lenders extend the Existing Maturity Date to the first anniversary of such Existing Maturity Date. Each Lender, acting in its sole discretion, shall, by written notice to the Administrative Agent given not later than the date that is the 10th day after the date of the Extension Request, or if such date is not a Business Day, the immediately following Business Day (the “Response Date”), advise the Administrative Agent in writing whether or not such Lender agrees to the requested extension. Each Lender that advises the Administrative Agent that it will not extend the Existing Maturity Date is referred to herein as a “Non-extending Lender”; provided, that any Lender that does not advise the Administrative Agent of its consent to such requested extension by the Response Date and any Lender that is a Defaulting Lender on the Response Date shall be deemed to be a Non-extending Lender. The Administrative Agent shall notify the Borrowers, in writing, of the Lenders’ elections promptly following the Response Date. The election of any Lender to agree to such an extension shall not obligate any other Lender to so agree. The Maturity Date may be extended no more than two times after the Second Amendment Effective Date pursuant to this Section 2.21.

(d)    Section 5.01(a) of the Existing Credit Agreement is amended and restated in its entirety as follows:

(a)    within 120 days after the end of each fiscal year of such Borrower (commencing with the fiscal year ending December 31, 2022), (I) with respect to each Borrower (other than CTWS and SJWTX), its audited consolidated balance sheet and related income statement, stockholders’ equity and statement of cash flows, as of the end of and for such year, setting forth in each case in comparative form the figures for the previous fiscal year, all reported on by independent public accountants of recognized national standing (without a “going concern” or like qualification, commentary or exception, and without any qualification or exception as to the scope of such audit) to the effect that such consolidated financial statements present fairly in all material respects the financial condition and results of operations of such Borrower and its consolidated Subsidiaries on a consolidated basis in accordance with GAAP consistently applied, accompanied by any management letter prepared by said accountants, (II) with respect to the Company, its unaudited and unreviewed consolidating balance sheet and related income statement and stockholders’ equity, and its consolidated statement of cash flows, as of the end of and for such year, setting forth in each case in comparative form the figures for the previous fiscal year, (III) with respect to CTWS, its unaudited and unreviewed consolidated balance sheet and related income statement, stockholders’ equity, and statement of cash flows, as of the end of and for such year, setting forth in each case in comparative form the figures for the previous fiscal year, (IV) with respect to SJWTX, its unaudited and reviewed consolidated balance sheet and related income statement, stockholders’ equity, and statement of cash flows, as of the end of and for such year, setting forth in each case in comparative form the figures for the previous fiscal year, and (V) the audited consolidated financial statements of each of The Connecticut Water Company and The Maine Water Company;

3.    Extension of Maturity Date. Each of the parties hereto agrees that the amendment set forth in Section 1(a) above shall be deemed to constitute an extension of the Maturity Date under Section 2.21 of the Existing Credit Agreement.

4.     Representations. Each Borrower hereby represents and warrants to the Administrative Agent and the Lenders after giving effect to this Amendment that: (a) it has all necessary power and authority to execute and deliver this Amendment and perform its obligations hereunder and under the Amended Credit Agreement, (b) no Default or Event of Default related to such Borrower exists both before and after giving effect to this Amendment, (c) this Amendment and the Loan Documents, as amended hereby, constitute the legal, valid and binding obligations of such Borrower and are enforceable against such Borrower in accordance with their terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law, (d) all representations and warranties of such Borrower contained in the Amended Credit Agreement and all other Loan Documents are true and correct in all material respects with the same effect as though made on and as of the date hereof (it being understood and agreed that any representation or warranty which by its terms is made as of a specified date shall be required to be true and correct in all material respects only as of such specified date, and that any representation or warranty which is subject to any materiality qualifier shall be required to be true and correct in all respects) and (e) the execution and delivery of this Amendment and the performance by such Borrower of its obligations hereunder and under the Amended Credit Agreement will not violate or result in a default under any Material Agreement to which such Borrower is a party.

Except as herein specifically agreed, the Existing Credit Agreement and each other Loan Document are hereby ratified and confirmed and shall remain in full force and effect according to their terms. Except as specifically set forth herein, the execution, delivery and effectiveness of this Amendment shall not operate as a waiver of any right, power, privilege or remedy of the Administrative Agent or any Lender under the Existing Credit Agreement or any of the other Loan Documents, or constitute a waiver of any provision of the Existing Credit Agreement or any of the other Loan Documents. This Amendment shall not constitute a course of dealing with the Administrative Agent or any Lender at variance with the Amended Credit Agreement or the other Loan Documents such as to require further notice by such Person to require strict compliance with the terms of the Amended Credit Agreement and the other Loan Documents in the future. Each Borrower acknowledges and expressly agrees that the Administrative Agent and each Lender reserves the right to, and does in fact, require strict compliance with all terms and provisions of the Amended Credit Agreement and the other Loan Documents. Each Borrower hereby affirms that it is indebted to the Administrative Agent and each Lender under the terms and conditions of the Amended Credit Agreement and the other Loan Documents, each of which constitutes the valid and binding obligation of such Borrower, enforceable in accordance with their respective terms, and that no offsets, expenses or counterclaims to its obligations thereunder exist.

EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AMENDMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 7.

8.    JUDICIAL REFERENCE. IN THE EVENT ANY LEGAL PROCEEDING IS FILED IN A COURT OF THE STATE OF CALIFORNIA (THE “COURT”) BY OR AGAINST ANY BORROWER OR ANY CREDIT PARTY IN CONNECTION WITH ANY CONTROVERSY, DISPUTE OR CLAIM DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AMENDMENT, THE CREDIT AGREEMENT, THE OTHER LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY) (EACH, A “CLAIM”) AND THE WAIVER SET FORTH IN SECTION 7 IS NOT ENFORCEABLE IN SUCH ACTION OR PROCEEDING, EACH BORROWER AND THE CREDIT PARTIES (EACH BY ITS ACCEPTANCE HEREOF) AGREE AS FOLLOWS:

NEITHER THIS AMENDMENT NOR THE AMENDED CREDIT AGREEMENT LIMITS THE RIGHT OF ANY BORROWER OR ANY CREDIT PARTY TO EXERCISE OR OPPOSE ANY OF THE RIGHTS AND REMEDIES DESCRIBED IN CLAUSES (A) – (D) OF THIS SECTION AND ANY SUCH EXERCISE OR OPPOSITION DOES NOT WAIVE THE RIGHT OF ANY BORROWER OR ANY CREDIT PARTY TO A REFERENCE PROCEEDING PURSUANT TO THIS AMENDMENT OR THE AMENDED CREDIT AGREEMENT.

(c)    UPON THE WRITTEN REQUEST OF ANY BORROWER OR ANY CREDIT PARTY, THE BORROWERS AND THE CREDIT PARTIES SHALL SELECT A SINGLE REFEREE, WHO SHALL BE A RETIRED JUDGE OR JUSTICE.

(f)    EACH BORROWER AND EACH CREDIT PARTY RECOGNIZES AND AGREES THAT ALL CLAIMS RESOLVED IN A GENERAL REFERENCE PROCEEDING PURSUANT TO THIS SECTION 8 WILL BE DECIDED BY A REFEREE AND NOT BY A JURY.
