Section 7.2Insurance. The Company will, and will cause each of its Subsidiaries to, maintain, with financially sound and reputable insurers, insurance with respect to their respective Properties and businesses against casualties and contingencies of such types, on such terms and in such amounts (including deductibles, co-insurance and self-insurance, if adequate reserves are maintained with respect thereto) as is customary in the case of entities of established reputations engaged in the Water Business or a similar business and similarly situated, other than any failure to maintain such insurance that would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

Section 7.3Maintenance of Properties. The Company will, and will cause each of its Subsidiaries to, maintain and keep, or cause to be maintained and kept, their respective Properties in good repair, working order and condition (other than ordinary wear and tear), so that the business carried on in connection therewith may be properly conducted at all times, provided that this Section 7.3 shall not prevent the Company or any Subsidiary from discontinuing the operation and the maintenance of any of its Properties if such discontinuance is desirable in the conduct of its business and the Company has concluded that such discontinuance could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

The Company will, and will cause each of its Subsidiaries to, file all tax returns required to be filed in any jurisdiction and to pay and discharge all taxes shown to be due and payable on such returns and all other taxes, assessments, governmental charges or levies imposed on them or any of their Properties, income or franchises, to the extent the same have become due and payable and before they become delinquent, and all claims for which sums have become due and payable that have or might become a Lien on Properties of the Company or any Subsidiary, provided that neither the Company nor any Subsidiary need pay any such tax, assessment, charge, levy or claim if: (a) the amount, applicability or validity thereof is contested by the Company or such Subsidiary on a timely basis in Good Faith and appropriate proceedings, and the Company or a Subsidiary has established adequate reserves therefor in accordance with GAAP on the books of the Company or such Subsidiary; or (b) the nonfiling or nonpayment, as the case may be, of all such taxes, assessments, charges, levies and claims could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

Section7.5Corporate Existence. Subject to Section 8.2, the Company will at all times preserve and keep its corporate existence in full force and effect. Subject to Sections 8.2 and 8.8, the Company will at all times preserve and keep in full force and effect the corporate, limited liability company or other applicable existence of each of its Subsidiaries (unless merged into the Company or a Wholly-Owned Subsidiary) and all rights and franchises of the Company and its Subsidiaries unless, in the Good Faith judgment of the Company, the termination of or failure to preserve and keep in full force and effect such corporate existence, right or franchise could not, individually or in the aggregate, have a Material Adverse Effect.

Section 7.6Books and Records. The Company will, and will cause each of its Subsidiaries to, maintain proper books of record and account in conformity with GAAP and in conformity in all material respects with all applicable requirements of any Governmental Authority having legal or regulatory jurisdiction over the Company or such Subsidiary, as the case may be. The Company will, and will cause each of its Subsidiaries to, keep books, records and accounts which, in reasonable detail, accurately reflect in all material respects all transactions and dispositions of assets. The Company and its Subsidiaries have devised a system of internal accounting controls sufficient to provide reasonable assurances that their respective books, records, and accounts accurately reflect all transactions and dispositions of assets and the Company will, and will cause each of its Subsidiaries to, continue to maintain such system.

Section 7.7Subsidiary Guarantors.

(a)enter into an agreement in form and substance satisfactory to the Bank providing for the guaranty by such Subsidiary, on a joint and several basis with all other such Subsidiaries, of (i) the prompt payment in full when due of all amounts payable by the Company pursuant to the Revolver Note (whether for principal, interest or otherwise) and this Agreement, and the Notes if elected by the Company or required by the Noteholders, including all indemnities, fees and expenses payable by the Company thereunder, and (ii) the prompt, full and faithful performance, observance and discharge by the Company of each and every covenant, agreement, undertaking and provision required pursuant to the Revolver Note or this Agreement to be performed, observed or discharged by it;

(b)deliver the following to the Bank (i) an executed counterpart of such Subsidiary Guaranty, (ii) a certificate signed by an authorized officer of such Subsidiary containing representations and warranties on behalf of such Subsidiary to the same effect, mutatis mutandis, as those contained in Sections 4.1, 4.2, 4.6, 4.7, 4.10 and 4.11 of this Agreement (but with respect to such Subsidiary and such Subsidiary Guaranty rather than the Company), (iii) all documents reasonably requested by the Bank to evidence the due organization, continuing existence and good standing of such Subsidiary and the due authorization by all requisite action on the part of such Subsidiary of the execution and delivery of such Subsidiary Guaranty and the performance by such Subsidiary of its obligations

thereunder, and (iv) an opinion of counsel reasonably satisfactory to the Bank covering such matters relating to such Subsidiary and such Subsidiary Guaranty as the Bank may reasonably request; and

(c)at the election of the Company and by notice to the Bank, any Subsidiary Guarantor may be discharged from its obligations under its Subsidiary Guaranty and be automatically released from its obligations thereunder without the need for the execution or delivery of any other document by the Bank, provided that (i) if such Subsidiary Guarantor is a guarantor or otherwise liable for or in respect of the Term Note Facility and/or any Material Credit Facility, then such Subsidiary Guarantor shall have been released and discharged (or will be released and discharged concurrently with the release of such Subsidiary Guarantor under its Subsidiary Guaranty) from its liability for or in respect of all such Indebtedness, (ii) at the time of, and after giving effect to, such release and discharge, no Default or Event of Default shall be existing, (iii) no amount is then due and payable under such Subsidiary Guaranty, (iv) if in connection with such Subsidiary Guarantor being released and discharged from any Indebtedness described in the preceding clause (i) any fee, debt repayment or other consideration is given or paid to any holder of such Indebtedness, the Bank may elect to receive equivalent pro-rata consideration substantially concurrently therewith, and (v) the Company shall simultaneously provide to the Bank a certificate of a Responsible Officer certifying as to the matters set forth in the preceding clauses (i) through (iv).

Section 7.8Collateral. The Company shall take all actions necessary to insure that the Collateral Agent, on behalf of the Secured Parties, has and continues to have in all relevant jurisdictions duly and validly created, attached, perfected and enforceable first priority Liens on all Collateral. The Company shall cause the Obligation to constitute direct senior secured obligations of the Company and to be senior in right of payment and to rank senior in right of security with respect to all Collateral granted in the Security Documents to all other Indebtedness of the Company; provided, however, if the Company incurs Indebtedness permitted hereunder (including the Term Note Facility) such Indebtedness may be secured equally and ratably with the Indebtedness evidenced by the Revolver Note pursuant to documentation reasonably acceptable to the Bank in substance and form, including an intercreditor agreement and opinions of counsel to the Company and/or any such Subsidiary, as the case may be.

Each Holder, by its acceptance of the Revolver Note, will have agreed to be bound by and entitled to the benefits of this Section 16 as though it were a named Party. On reasonable request by the Company in connection with the delivery to any Holder of information required to be delivered to such holder under this Agreement or requested by such Holder, such Holder will enter into an agreement with the Company embodying this Section 16.

its sole discretion may determine, provided that Holder will not be obligated to proceed against any Collateral or Person.

11. Taxes. If any payments are made from outside the United States, Maker shall not deduct any foreign taxes from such payments. If any such taxes are imposed on any such payments (including payments under this Section 11), Maker shall pay the taxes and also pay to Holder, at the time interest is paid, such additional amount as Holder may specify is necessary to preserve the after-tax yield Holder would have received if such taxes were not imposed.

Payments by Maker to Holder shall be made without deduction of United States withholding or similar taxes. If Maker is required to pay United States withholding or similar taxes, Maker shall pay such taxes in addition to the other amounts due Holder.

All interest and other charges, fees, other things of value and reimbursable costs Maker is or may become obligated to pay or reimburse to Holder in connection with the Revolver, and which constitute “interest” within the meaning of Arizona Revised Statutes Sections 44-1201 et seq., will be items of interest in addition to interest accrued at the Revolver Rate on the OPB, which Maker hereby contracts in writing to pay.
