Section 2.01 Effect on Capital Stock . At the Effective Time, by virtue of the Merger and without any action on the part of SJW, Merger Sub, CTWS or any holder of any of the following securities:

(a) Conversion of CTWS Common Stock . Subject to Section  2.02 , each share of common stock, without par value, of CTWS (“ CTWS Common Stock ”, and such shares, “ CTWS Common Shares ”), other than any Cancelled CTWS Common Shares, issued and outstanding immediately prior to the Effective Time shall be automatically converted into and shall thereafter represent the right to receive an amount in cash equal to $70.00 per share, payable without interest (the “ Merger Consideration ”). All such CTWS Common Shares, when so converted, shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of a certificate that immediately prior to the Effective Time represented any such CTWS Common Shares (each such certificate, a “ Certificate ”) or CTWS Common Shares held in direct registration form (“ Book-Entry Shares ”) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration, without interest (subject to

3

any withholding of applicable Tax in accordance with Section  2.02(h) ), to be paid in consideration therefor in accordance with Section  2.02 . Notwithstanding the foregoing, if between the Execution Date and the Effective Time the outstanding CTWS Common Shares shall have been changed into a different number of shares or a different class, by reason of any stock dividend, recapitalization, split, reverse split, combination, consolidation, subdivision, reclassification or exchange of shares, or any similar event shall have occurred, then the Merger Consideration shall be equitably adjusted, without duplication, to proportionally reflect such change; provided , however , that this sentence shall not be construed to permit CTWS to take any action with respect to its securities that is prohibited by Section  5.01(a) .

(b) Cancelled CTWS Common Shares . Each CTWS Common Share that is owned directly or indirectly by SJW or Merger Sub or any of their respective Subsidiaries immediately prior to the Effective Time or held directly or indirectly by CTWS or any CTWS Subsidiary immediately prior to the Effective Time (in each case, other than any CTWS Common Share held on behalf of third parties) (the “ Cancelled CTWS Common Shares ”) shall be cancelled and retired and shall cease to exist, and no consideration shall be delivered in exchange for such cancellation and retirement.

(c) Conversion of Merger Sub Common Stock . At the Effective Time, each share of common stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one validly issued, fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation and shall constitute the only outstanding shares of capital stock of the Surviving Corporation. From and after the Effective Time, all certificates representing the common stock of Merger Sub shall be deemed for all purposes to represent the number of shares of common stock of the Surviving Corporation into which they were converted in accordance with the immediately preceding sentence.

Section 2.02 Paying Agent .

(a) Paying Agent . Prior to the Effective Time, SJW shall appoint a bank or trust company with the prior approval of CTWS (not to be unreasonably withheld) to act as paying agent (the “ Paying Agent ”) for the payment of the Merger Consideration. At or prior to the Effective Time, SJW shall deposit with the Paying Agent, for the benefit of the holders of CTWS Common Stock entitled to receive Merger Consideration under Section  2.01(a) , for exchange in accordance with this Article  II through the Paying Agent, cash sufficient to pay the aggregate amount of Merger Consideration deliverable pursuant to Section  2.01 (such cash amount being hereinafter referred to as the “ Fund ”).

(b) Letter of Transmittal . As promptly as practicable after the Effective Time, and in any event not later than the fourth Business Day thereafter, SJW shall cause the Paying Agent to mail to each holder of record of CTWS Common Stock a form of letter of transmittal (the “ Letter of Transmittal ”) which shall specify that delivery shall be effected, and risk of loss and title to any Certificates or Book-Entry Shares shall pass, only upon delivery of such Certificates or Book-Entry Shares to the Paying Agent and shall be in such customary form and have such other customary provisions as SJW may specify subject to CTWS’s reasonable approval, together with instructions thereto.

4

(c) Merger Consideration Received in Connection with Exchange .

(i) After the Effective Time, upon the surrender of a Certificate for cancelation to the Paying Agent, together with the Letter of Transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Paying Agent, the holder of such Certificate shall be entitled to receive in exchange therefor, the Merger Consideration into which the CTWS Common Shares previously represented by such Certificate have been converted pursuant to Section  2.01(a) . In the event of a transfer of ownership of CTWS Common Stock that is not registered in the transfer records of CTWS, the Merger Consideration may be issued to a transferee if the Certificate (or, for Book-Entry Shares, proper evidence of such transfer) representing such CTWS Common Stock is presented to the Paying Agent, accompanied by all documents reasonably required to evidence and effect such transfer, including evidence that any applicable stock transfer Taxes have been paid. Until surrendered as contemplated by this Section  2.02(c) , each Certificate or Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration which the holder of such Certificates or Book-Entry Shares were entitled to receive pursuant to Section  2.01 . No interest shall be paid or shall accrue on the cash payable under this Section  2.02(c) or under Section  2.02(d) .

(ii) As promptly as practicable following the Effective Time, the Paying Agent shall deliver to each former holder of Book-Entry Shares the Merger Consideration into which such CTWS Common Shares have been converted pursuant to Section  2.01(a) . Notwithstanding anything to the contrary in this Agreement, no former record holder of a Book-Entry Share shall be required to deliver a Certificate or an executed Letter of Transmittal to the Paying Agent to receive the Merger Consideration in respect of such Book-Entry Shares. In lieu thereof, such former record holder shall, upon receipt by the Paying Agent of an “agent’s message” in customary form (or such other evidence, if any, as the Paying Agent may reasonably request), be entitled to receive, and SJW shall cause the Paying Agent to deliver as promptly as reasonably practicable after the Effective Time (and in any event not later than the third Business Day thereafter), the Merger Consideration in respect of each Book-Entry Share of such former holder, and such Book-Entry Shares shall forthwith be cancelled.

(d) No Further Ownership Rights in CTWS Common Stock . The Merger Consideration paid in respect of shares of CTWS Common Shares upon the surrender for exchange in accordance with the terms of this Article  II shall be deemed to have been issued and paid in full satisfaction of all rights pertaining to such CTWS Common Shares. From and after the Effective Time, there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of CTWS Common Shares that were outstanding immediately prior to the Effective Time. Subject to the last sentence of Section  2.02(f) , if, after the Effective Time, any Certificates or Book-Entry Shares are presented for transfer to the Surviving Corporation, SJW or the Paying Agent for any reason, they shall be canceled and exchanged as provided in this Article  II .

5

(e) Termination of Fund . Any portion of the Fund (including any interest or other amounts received with respect thereto) that remains undistributed to the holders of CTWS Common Stock for six months after the Effective Time shall be delivered to SJW, upon demand, and any former holder of CTWS Common Stock who has not previously complied with this Article  II shall thereafter look only to SJW for payment of its claim for Merger Consideration pursuant to this Article  II .

(f) No Liability . None of SJW, CTWS, the Surviving Corporation or the Paying Agent shall be liable to any Person in respect of any portion of the Fund delivered to any Governmental Entity pursuant to any applicable abandoned property, escheat or similar Law. Any portion of the Fund which remains undistributed to the holders of Certificates immediately prior to the date on which the Fund would otherwise escheat to, or become the property of, any Governmental Entity shall, to the extent permitted by applicable Law, become the property of SJW, free and clear of all claims or interests of any Person previously entitled thereto.

(g) Investment of Fund . The Fund shall not be used for any purpose other than a purpose expressly provided for in this Agreement. The Paying Agent shall invest any cash in the Fund as reasonably directed by SJW; provided , however , that any investment shall be in obligations of or guaranteed as to principal and interest by the U.S. government in commercial paper obligations rated A-1 or P-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Financial Services, LLC, respectively, in certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $10 billion (based on the most recent financial statements of such bank that are then publicly available), or in money market funds having a rating in the highest investment category granted by a recognized credit rating agency at the time of acquisition or a combination of the foregoing and, in any such case, no such instrument shall have a maturity exceeding three months. Any interest and other income resulting from such investments shall be paid to SJW, as determined by SJW in accordance with the terms and conditions of its agreement with the Paying Agent. Notwithstanding the foregoing, to the extent that there are any losses with respect to such investments or for any other reason any amount in the Fund is below that required to make prompt payment of the payments contemplated by this Article  II , SJW shall promptly replace, restore or supplement the cash lost through such investments or other events, as applicable, in the Fund so as to ensure that the Fund is at all times maintained at a level sufficient for the Paying Agent to make the payments contemplated by this Article  II .

(h) Withholding Rights . Each of SJW, Merger Sub, CTWS and the Paying Agent (without duplication) shall be entitled to deduct and withhold from amounts otherwise payable pursuant to this Agreement any amounts required to be deducted and withheld with respect to the making of such payment under applicable Tax Law. Amounts so withheld and paid over to the appropriate taxing authority shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction or withholding was made.

(i) Lost Certificates . If any Certificate has been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by SJW, the posting by such Person of a bond, in such reasonable and customary amount as SJW may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent (or, if subsequent to

6

the termination of the Fund and subject to Section  2.02(f) , SJW) shall deliver and pay, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration to be paid in respect of the CTWS Common Shares formerly represented by such Certificate, as contemplated by this Section  2.02 .

Section 2.03 Termination of CTWS Dividend Reinvestment Plan . If requested in writing by SJW, CTWS shall take such action as may be necessary to cause CTWS’s Third Amended and Restated Dividend Reinvestment and Common Stock Purchase Plan (the “ CTWS Dividend Reinvestment Plan ”) to be terminated immediately prior to the Effective Time in accordance with the terms of the CTWS Dividend Reinvestment Plan; provided , that the termination of the CTWS Dividend Reinvestment Plan will not have any effect on the CTWS Common Shares credited to the account of a participant in the CTWS Dividend Reinvestment Plan at the time of such termination or the right of such CTWS Common Shares to receive the Merger Consideration pursuant to Section  2.01(a) .

SJW and Merger Sub will have, on or prior to the Closing, all funds necessary to enable SJW or Merger Sub, as the case may be, to consummate the transactions contemplated by this Agreement, including payment of the aggregate Merger Consideration and the payment of all other amounts required to be paid hereunder. SJW has delivered to CTWS a true and complete fully executed copies of (a) the commitment letter, dated as of the date hereof, between SJW and JPMorgan Chase Bank, N.A., including all exhibits, schedules and annexes to such letter in effect as of the Execution Date (the “ Commitment Letter ”), pursuant to which and subject to the terms and conditions thereof each of the parties thereto (other than SJW) have severally committed to lend the amounts set forth therein to SJW (the provision of such funds as set forth therein, but subject to the provisions of Section  6.12 , the “ Financing ”) for the purposes set forth in such Commitment Letter and (b) any fee letters related thereto (in the case of such fee letters redacted only as to the fee amounts and other economic terms that could not adversely affect the amount, net proceeds, original issue discount, conditionality, availability or termination of the Financing). The Commitment Letter has not been amended or modified prior to the Execution Date, and, to the knowledge of SJW, no such amendment or modification is contemplated as of the Execution Date (excluding any amendment

9

solely to add lenders, lead arrangers, bookrunners, syndication agents or similar entities that have not executed the Commitment Letter as of the Execution Date) and, as of the Execution Date, the commitments contained in the Commitment Letter have not been withdrawn, terminated or rescinded in any respect. As of the Execution Date, the Commitment Letter is in full force and effect and constitutes the legal, valid and binding obligation of SJW and, to the knowledge of SJW, each of the other parties thereto, enforceable in accordance with its terms, except as enforcement may be limited by bankruptcy, insolvency, reorganization or similar Laws affecting creditors’ rights generally and by general principles of equity. There are no conditions precedent or contingencies related to the funding of the full amount of the Financing pursuant to the Commitment Letter, other than as expressly set forth in the Commitment Letter. Subject to the terms and conditions of the Commitment Letter, the net proceeds contemplated from the Financing, together with other financial resources of SJW, including contemplated cash on hand of SJW, will, in the aggregate, be sufficient for the satisfaction of all of SJW’s and Merger Sub’s obligations under this Agreement, including the payment of the aggregate Merger Consideration and all fees and expenses reasonably expected to be incurred in connection therewith. As of the Execution Date, (i) no event has occurred which would constitute a breach or default (or an event which with or without notice or lapse of time or both could reasonably be expected to constitute a breach or default) on the part of SJW under the Commitment Letter or, to the knowledge of SJW, any other party to the Commitment Letter, and (ii) assuming the accuracy of the representations and warranties set forth in Section  4.06 and satisfaction of the conditions to SJW’s obligation to consummate the Merger, or waiver of such conditions, SJW does not have any reason to believe that any of the conditions to the Financing will not be satisfied or that the full amount of the Financing and any other funds necessary for the satisfaction of all of SJW’s obligations under this Agreement and the payment of all fees and expenses reasonably expected to be incurred in connection therewith will not be available to SJW on the Closing Date. As of the Execution Date, there are no side letters or other agreements, Contracts or arrangements that could affect the availability of the Financing or any portion thereof other than as expressly set forth in the Commitment Letter and delivered to CTWS prior to the Execution Date. SJW has fully paid (or caused to be paid) all commitment fees or other fees required to be paid on or prior to Execution Date in connection with the Financing.

Section 3.06 Reporting Documents; Undisclosed Liabilities .

(a) SJW has furnished or filed all reports, schedules, forms, statements and other documents (including exhibits and other information incorporated therein) required to be furnished or filed by SJW with the SEC since January 1, 2015 (such documents being collectively referred to as the “ SJW Reporting Documents ”).

(b) Each SJW Reporting Document (i) at the time filed or furnished, complied in all material respects with the requirements of the Sarbanes-Oxley Act of 2002 (“ SOX ”), the Exchange Act and the Securities Act, as applicable to such SJW Reporting Document and (ii) did not at the time it was filed or furnished (or if amended or superseded by a filing or amendment prior to the date of this Agreement, then at the time of such filing or amendment) contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. Each of the consolidated financial statements of SJW included in the SJW Reporting Documents complied at the time it was filed

10

as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto, was prepared in accordance with United States generally accepted accounting principles (“ GAAP ”) (except, as indicated in the notes thereto, in the case of unaudited statements, as permitted by the rules and regulations of the SEC) applied on a consistent basis during the periods involved (except as may be indicated in the notes thereto) and fairly presented in all material respects the consolidated financial position of SJW and its consolidated subsidiaries as of the dates thereof and the consolidated results of their operations and cash flows for the periods shown (subject, in the case of unaudited statements, to normal year-end audit adjustments).

(c) Each of the principal executive officer of SJW and the principal financial officer of SJW (or each former principal executive officer of SJW and each former principal financial officer of SJW) has made all applicable certifications required by Rule 13a-14 or 15d-14 under the Exchange Act and Sections 302 and 906 of SOX with respect to the SJW Reporting Documents, and the statements contained in such certifications are true and correct.

(a) From the date of this Agreement until the earlier of the Effective Time or the date of the termination of this Agreement in accordance with Article  VIII , except as expressly permitted pursuant to this Section  5.03 , CTWS shall not, nor shall it authorize or permit any of its Affiliates or any of its or their respective Representatives to, (i) directly or indirectly solicit, initiate, knowingly encourage or knowingly facilitate any CTWS Takeover Proposal or any inquiry or proposal that would reasonably be expected to lead to a CTWS Takeover Proposal or (ii) directly or indirectly participate in any discussions or negotiations with any Person (other than CTWS’s Representatives) regarding, or furnish to any Person (other than CTWS’s Representatives) any non-public information with respect to, any CTWS Takeover Proposal or any inquiry or proposal that would reasonably be expected to lead to a CTWS Takeover Proposal (other than to state that the terms of this Section  5.03 prohibit any such discussions). CTWS shall, and shall cause its Subsidiaries and direct its and their respective Representatives to, immediately cease and cause to be terminated all existing discussions or negotiations with any Person conducted heretofore with respect to any CTWS Takeover Proposal or any inquiry or proposal that would reasonably be expected to lead to a CTWS Takeover Proposal, request the prompt return or destruction of all confidential information previously furnished to any such Person or its Representatives and immediately terminate all physical and electronic dataroom access previously granted to any such Person or its Representatives. Notwithstanding the foregoing, at any time prior to obtaining the CTWS Shareholder Approval, in response to a bona fide written CTWS Takeover Proposal that the CTWS Board determines in good faith (after consultation with outside counsel and the CTWS Financial Advisor or another financial advisor of nationally recognized reputation) constitutes or is reasonably likely to lead to a Superior CTWS Proposal, and that did not result from a material breach of this Section  5.03(a) , CTWS, and its Representatives at the request of CTWS, may, subject to compliance with

42

Section  5.03(c) , (x) furnish information with respect to CTWS and the CTWS Subsidiaries to the Person making such CTWS Takeover Proposal (and its Representatives) ( provided that all such information has previously been provided to SJW or is provided to SJW prior to or substantially concurrent with the time it is provided to such Person) pursuant to a customary confidentiality agreement that, taken as a whole, is not materially less restrictive of such Person than the Confidentiality Agreement; provided that such confidentiality agreement shall not be required to contain standstill provisions (a “ CTWS Acceptable Confidentiality Agreement ”) and (y) participate in discussions regarding the terms of such CTWS Takeover Proposal and the negotiation of such terms with, and only with, the Person making such CTWS Takeover Proposal (and such Person’s Representatives). Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in this Section  5.03(a) by any CTWS Subsidiary or any of its or their Representatives shall constitute a breach of this Section  5.03(a) by CTWS.

(b) Except as set forth below, neither the CTWS Board nor any committee thereof shall (i) (A) withdraw (or modify or qualify in any manner adverse to SJW or Merger Sub), or propose publicly to withdraw (or modify or qualify in any manner adverse to SJW or Merger Sub), the CTWS Recommendation or (B) adopt, approve, recommend or declare advisable, or propose publicly to adopt, approve, recommend or declare advisable, any CTWS Takeover Proposal (any action in this clause (i) being referred to as a “ CTWS Adverse Recommendation Change ”) or (ii) approve, recommend or declare advisable, or propose publicly to approve, recommend or declare advisable, or allow CTWS or any of its Affiliates to execute or enter into, any Acquisition Agreement (other than a CTWS Acceptable Confidentiality Agreement) constituting or that would reasonably be expected to lead to any CTWS Takeover Proposal. Notwithstanding the foregoing, at any time prior to obtaining the CTWS Shareholder Approval, the CTWS Board may make a CTWS Adverse Recommendation Change if the CTWS Board determines in good faith (after consultation with outside counsel and the CTWS Financial Advisor or another financial advisor of nationally recognized reputation) that the failure to do so would be inconsistent with its fiduciary duties under applicable Law; provided , however , that CTWS shall not be entitled to exercise its right to make a CTWS Adverse Recommendation Change in connection with a CTWS Takeover Proposal or a Superior CTWS Proposal until after five Business Days following SJW’s receipt of written notice (a “ CTWS Notice of Recommendation Change ”) from CTWS advising SJW that the CTWS Board intends to make a CTWS Adverse Recommendation Change and specifying the reasons therefor, including the terms and conditions of any CTWS Takeover Proposal or Superior CTWS Proposal that is the basis of the proposed action by the CTWS Board (it being understood and agreed that any amendment to the financial terms or any other material term of such CTWS Takeover Proposal or Superior CTWS Proposal shall require a new CTWS Notice of Recommendation Change, except that any subsequent notice period shall be reduced to three Business Days). In determining whether to make a CTWS Adverse Recommendation Change, the CTWS Board shall take into account any changes to the terms of this Agreement proposed by SJW in response to a CTWS Notice of Recommendation Change or otherwise, and, if requested by SJW, CTWS shall engage in good faith negotiations with SJW regarding any changes to the terms of this Agreement proposed by SJW during the applicable required notice period.

43

(c) In addition to the obligations of CTWS set forth in Sections  5.03(a) and 5.03(b) , CTWS shall promptly (and in any event within one Business Day of receipt thereof by CTWS or any of its Affiliates or any of its or their Representatives) advise SJW in writing of any CTWS Takeover Proposal or any inquiry or proposal that would reasonably be expected to lead to a CTWS Takeover Proposal, the material terms and conditions of any such CTWS Takeover Proposal or inquiry or proposal (including any changes thereto) and the identity of the Person making any such CTWS Takeover Proposal or inquiry or proposal.

(d) Nothing contained in this Section  5.03 shall prohibit CTWS from complying with its disclosure obligations under U.S. federal or state Laws regarding a CTWS Takeover Proposal or a CTWS Adverse Recommendation Change, including with respect to (i) disclosing a position contemplated by Rule 14d-9 and Rule 14e-2 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act or (ii) making any “stop, look and listen” communication of the type contemplated by Rule 14d-9(f) under the Exchange Act; provided , however , that if any such disclosure or communication does not reaffirm the CTWS Recommendation, or has the effect of modifying or qualifying the CTWS Recommendation in any manner adverse to SJW, such disclosure or communication shall constitute a CTWS Adverse Recommendation Change.

(e) For purposes of this Agreement:

“ CTWS Takeover Proposal ” means any proposal or offer (whether or not in writing) made by any Person or Persons other than SJW or any of its Affiliates, with respect to any (i) merger, amalgamation, consolidation, share exchange, other business combination, recapitalization, liquidation, dissolution or similar transaction involving CTWS or any CTWS Subsidiary, (ii) sale, lease, contribution or other disposition, directly or indirectly (including by way of merger, amalgamation, consolidation, share exchange, other business combination, recapitalization, liquidation, dissolution, partnership, joint venture, sale of capital stock or voting securities of, or other equity interests in, a CTWS Subsidiary or otherwise) of any business or assets of CTWS or the CTWS Subsidiaries representing 15% or more of the consolidated revenues, net income or assets of CTWS and the CTWS Subsidiaries, taken as a whole, (iii) issuance, sale or other disposition, directly or indirectly, to any Person (or the stockholders of any Person) or group of securities (or options, rights or warrants to purchase, or securities convertible into or exchangeable or exercisable for, such securities) representing 15% or more of the total outstanding voting power of CTWS, (iv) transaction in which any Person (or the stockholders of any Person) shall acquire, directly or indirectly, beneficial ownership, or the right to acquire beneficial ownership, or formation of any group which beneficially owns or has the right to acquire beneficial ownership of, 15% or more of the total outstanding voting power of CTWS or (v) combination of the foregoing (in each case, other than the Merger).

For the avoidance of doubt, any CTWS Performance Share Units that do not become Vested Performance Share Units pursuant to the determination set forth herein shall be cancelled with no consideration paid therefor.

(B) Awards Granted on or After Date of this Agreement . At the Effective Time, each CTWS Performance Share Unit award that was granted on or after the date of this Agreement and that is outstanding and unvested immediately prior to the Effective Time shall, by virtue of the Merger and without any action on the part of the holder thereof, be assumed by SJW and converted automatically (without regard to the attainment of the applicable performance goals) into a time-based award (each, an “ Assumed PSU Award ”) covering a number of restricted share units of SJW equal to the product obtained by multiplying (x) the target number of restricted share units outstanding and unvested under such CTWS Performance Share Unit award immediately prior to the Closing by (y) the Equity Award Ratio, with any fractional restricted share units rounded down to the next lower whole number of restricted share units. Each Assumed PSU Award shall thereafter be subject to the same service-based vesting terms (such as vesting at the conclusion of a fiscal year for annual awards and ratable vesting over a three-year period for long-term awards measured from the grant date of the applicable CTWS Performance Share Unit award (as specified in the agreement evidencing the award)) and other terms and conditions, but not any performance-based vesting terms, applicable to the converted CTWS Performance Share Unit award under the applicable CTWS Stock Plan and the agreement evidencing the award, including as to the settlement date for the award following vesting; provided , however, that notwithstanding anything to the contrary in the terms and conditions applicable to the converted CTWS Performance Share Unit award under the applicable CTWS Stock Plan and the agreement evidencing the award, each Assumed PSU Award shall be subject to accelerated vesting in full upon a termination of the participant’s employment by the Surviving Corporation (or its successor) without “Cause” (as defined in the CTWS Change in Control Severance Plan) within one year following the Closing.

Each Adjusted RSU Award shall otherwise be subject to the same terms and conditions applicable to the converted CTWS Restricted Share Unit award under the applicable CTWS Stock Plan and the agreements evidencing the award, including as to vesting and payment of cash or stock, as applicable, upon vesting; provided , however, that notwithstanding anything to the contrary in the terms and conditions applicable to the converted CTWS Restricted Share Unit award under the applicable CTWS Stock Plan and the agreement evidencing the award, each Adjusted RSU Award shall be subject to accelerated vesting in full upon a termination of the participant’s employment by the Surviving Corporation (or its successor) without “Cause” (as defined in the CTWS Change in Control Severance Plan) within one year following the Closing.

In the event that all conditions set forth in the Commitment Letter have been satisfied (other than the consummation of the Merger) or, upon funding shall be satisfied, SJW and its Affiliates shall use their reasonable best efforts to cause the Persons providing the Financing (the “ Financing Parties ”) to fund on the Closing Date the Financing, to the extent the proceeds thereof are required to consummate the Merger and the other transactions contemplated hereby. SJW shall, promptly after obtaining knowledge thereof (and in any event within two Business Days), give CTWS written notice of any (A) breach (or threatened breach) or default (or any event or circumstance that, with or without notice, lapse of time or both, could reasonably be expected to give rise to any breach or default) by a Financing Party or any party to any definitive document related to the Financing, (B) actual or threatened withdrawal, repudiation or termination of the Financing by the Financing Parties, (C) amendment or modification of, or waiver under, the Commitment Letter or (D) change, circumstance or event which causes SJW to believe that it will not be able to timely obtain all or any portion of the Financing on the terms, in

60

the manner or from the Financing Parties or sources contemplated by the definitive documents related to the Financing, to the extent the proceeds thereof are required to consummate the Merger and the other transactions contemplated hereby. SJW shall (i) keep CTWS informed on a reasonably current basis of the status of its efforts to arrange the Financing, and (ii) provide CTWS with copies of all executed material definitive agreements related to the Financing. SJW shall, and shall use its reasonable best efforts to cause the Financing Sources to, provide CTWS and its Representatives with such access to SJW and the Financing Sources as CTWS and its Representatives may reasonably request for the purpose of allowing CTWS and its Representatives to understand the status of SJW’s efforts to arrange the Financing; provided , that SJW and its Representatives shall be permitted to participate in any such discussions or communications. Neither SJW nor its Affiliates shall amend, modify or replace the Commitment Letter without the prior written approval of CTWS to the extent such amendment, modification or replacement could reasonably be expected to (I) reduce the aggregate amount of the Financing or the net cash proceeds from the Financing (including by increasing the amount of fees to be paid or original issue discount) below the amount required by SJW to consummate the transactions contemplated by this Agreement, (II) impose new or additional conditions or otherwise expand, amend or modify any of the conditions to the receipt of the Financing in a manner that could reasonably be expected to (1) delay or prevent or make less likely the funding of the Financing (or satisfaction of the conditions to the Financing) or (2) adversely impact the ability of SJW to enforce its rights against the Financing Parties or any other parties to the Commitment Letter or the definitive agreements with respect thereto, or (III) make it less likely that the Financing would be funded (including by making the conditions to obtaining the Financing less likely to occur) or otherwise prevent or delay or impair the ability or likelihood of SJW to consummate the Merger and the other transactions contemplated hereby on the Closing Date; provided that notwithstanding the foregoing, SJW may modify, supplement or amend the Commitment Letter to add lenders, lead arrangers, bookrunners, syndication agents or similar entities (that have not executed the Commitment Letter as of the Execution Date). If funds in the amounts set forth in the Commitment Letter, or any portion thereof, become unavailable, or it becomes reasonably likely that such funds may become unavailable to SJW on the terms and conditions set forth therein and, in each case, such funds are required by SJW to consummate the transactions contemplated by this Agreement, SJW shall, and shall cause its Affiliates, as promptly as practicable (and in any event within two Business Days) following the occurrence of such event to (x) notify CTWS in writing thereof and (y) use its reasonable best efforts to obtain substitute financing on terms and conditions not materially less favorable in the aggregate to SJW than those set forth in the Commitment Letter and in an amount sufficient to enable SJW to consummate the Merger and the other transactions contemplated hereby in accordance with its terms (the “ Substitute Financing ”). In the event that new commitment letters are entered into in accordance with any amendment, replacement, supplement or other modification of the Commitment Letter (including in connection with any Substitute Financing) permitted pursuant to this Section  6.12 , such new commitment letters shall be deemed to be a part of the “Financing” and deemed to be the “Commitment Letter” for all purposes of this Agreement. SJW shall promptly deliver to CTWS copies of any termination, amendment, modification, waiver or replacement of the Commitment Letter (including in connection with any Substitute Financing).

61

(b) SJW shall pay, or cause to be paid, as the same shall become due and payable, all fees and other amounts that become due and payable under the Commitment Letter or the related fee letters.

(c) Notwithstanding anything contained in this Agreement to the contrary, SJW expressly acknowledges and agrees that SJW’s obligations hereunder are not conditioned in any manner upon SJW obtaining the Financing, any Substitute Financing or any other financing. The failure, for any reason, of SJW to have sufficient cash available on the Closing Date to pay the consideration in Merger Consideration in accordance with Article  II or the failure to so pay the Merger Consideration on the Closing Date in accordance with the terms and conditions of this Agreement shall constitute a breach of this Agreement by SJW.

(d) CTWS shall, and shall cause each of the CTWS Subsidiaries to, and shall use its reasonable best efforts to cause its and their Representatives to, provide to SJW such customary cooperation, at SJW’s sole expense, as may be reasonably requested by SJW in connection with the Financing (which term, for purposes of this Section  6.12(d) , shall include any Substitute Financing and any issuance of debt or equity securities issued or incurred in lieu of any Financing or Substitute Financing), which efforts shall include using reasonable best efforts to:

(i) cause its management team, with appropriate seniority and expertise, including its senior executive officers, and independent accountants to assist SJW in SJW’s preparation for and to participate in a reasonable number of meetings (including customary one-on-one meetings), presentations, road shows, due diligence sessions, drafting sessions and sessions with lenders, investors and rating agencies, in each case, upon reasonable notice and at times and locations to be mutually agreed upon;

(ii) assist SJW with SJW’s preparation of customary rating agency presentations, road show materials, bank information memoranda, credit agreements, registration statements, prospectuses, bank syndication materials, offering documents, private placement memoranda and similar documents customarily required in connection with the Financing, including the marketing and syndication thereof, provided , that any such bank information memoranda, registration statements, prospectuses, bank syndication materials, offering documents, private placement memoranda and similar documents shall contain disclosure and pro forma financial statements reflecting the Surviving Corporation and/or its Subsidiaries as the obligor;

(iii) furnish SJW and the Financing Sources with all Required Information and, as may be reasonably requested by SJW in connection with the Financing, other customary financial and other information regarding CTWS and its Subsidiaries;
