On July 22, 1992 the Board of Directors of the San Jose Water Company (the “Company”) adopted the San Jose Water Company Executive Supplemental Retirement Plan (the “Plan”).

III. RETIREMENT BENEFIT

3.1 Retirement Benefit Formula. The actual Retirement Benefit to be paid under this Plan to a vested Participant beginning on his or her Benefit Commencement Date determined in accordance with Section 3.2 shall be calculated on the basis of the following formula for determining a Participant’s normal retirement benefit and shall be adjusted so that it is the Actuarial Equivalent of such normal retirement benefit after taking into account any Benefit Commencement Date prior to the Participant’s Normal Retirement Date and/or any form of payment other than a Single Life Annuity for the Participant:

3.2 Benefit Commencement Date. The following provisions shall govern the date on which a vested Participant’s Retirement Benefit as calculated under Section 3.1 shall commence, subject to the elective deferral provisions of Section 3.3 and the mandatory deferral provisions of Section 3.12. In the absence of any deferral effected pursuant to Section 3.3 or 3.12, such date shall constitute the Participant’s Benefit Commencement Date under the Plan.

5

(a) The Benefit Commencement Date for a vested Participant whose Separation from Service occurs on or after satisfying the requirements for a Normal Retirement Date shall be the first day of the first calendar month following such Separation of Service. The monthly retirement benefit which shall commence at that time shall be in the amount calculated under Section 3.1 and payable in the form of a Single Life Annuity. There shall be no actuarial increase to the dollar amount of the Participant’s monthly retirement benefit should the Benefit Commencement Date occur after his or her Normal Retirement Date.

(b) The Benefit Commencement Date for a vested Participant whose Separation from Service occurs on or after satisfying the requirements for an Early Retirement Date but before his or her Normal Retirement Date shall be the first day of the first calendar month following such Separation from Service. The monthly retirement benefit which shall commence at that time under Section 3.1 shall be payable in the form of a Single Life Annuity. However, the dollar amount of that monthly retirement benefit as calculated pursuant to Section 3.1 shall be reduced for the commencement of such benefit before the Participant’s Normal Retirement Date in accordance with the early retirement reduction factors set forth in the San Jose Water Company Retirement Plan as in effect on the Benefit Commencement Date.

(c) The Benefit Commencement Date for a vested Participant whose Separation from Service occurs before satisfying the requirements for an Early Retirement Date or a Normal Retirement Date shall be the first date of the first calendar month on which he or she satisfies the requirements for an Early Retirement Date or (if earlier) a Normal Retirement Date. The monthly retirement benefit which shall commence at that time under Section 3.1 shall be payable in the form of a Single Life Annuity. However, the dollar amount of that monthly retirement benefit as calculated pursuant to Section 3.1 shall be reduced, in accordance with the early retirement reduction factors set forth in the San Jose Water Company Retirement Plan as in effect on the Benefit Commencement Date, should such retirement benefit commence before the Participant’s Normal Retirement Date.

3.3 Election of Deferred Benefit Commencement Date. The following provisions shall govern any election by a Participant to receive his or her Retirement Benefit on a Deferred Benefit Commencement Date that is later than the date on which his or her Retirement Benefit would otherwise commence in accordance with Section 3.2:

(i) An Eligible Employee participating in the Plan during the 2007 calendar year may elect a Deferred Benefit Commencement Date at any time on or before December 31, 2007 by filing the appropriate deferral election form with the Committee.

(ii) An Eligible Employee who is first selected for participation in the Plan after December 31, 2007 may elect a Deferred Benefit Commencement Date by filing the appropriate election form with the Committee at any time prior to the date his or her participation in the Plan becomes effective.

(iii) Should a Participant wish at any time after December 31, 2008 to change the Benefit Commencement Date in effect for him or her pursuant to Section 3.2 (or any Deferred Benefit Commencement Date in effect for him or her at that time under this Section 3.3) to a later Deferred Benefit Commencement Date, then such Participant must file the appropriate deferral election form with the Committee at least twelve (12) months prior to the Benefit Commencement Date or Deferred Benefit Commencement Date in effect at the time for the Participant, and the deferral election shall in no event become effective or otherwise have any

6

force or applicability until the expiration of the twelve (12)-month period measured from the date such election is filed with the Committee. Accordingly, the new deferral election shall become null and void should the Participant’s pre-existing Benefit Commencement Date or Deferred Commencement Date occur within that twelve (12)-month period. The new Deferred Benefit Commencement Date elected by the Participant must be a date that is at least five (5) years later than the date on which the Participant’s Retirement Benefit would have otherwise commenced in the absence of the new deferral election.

3.4 Alternative Form of Benefit Payment. In lieu of the Single Life Annuity in which a Participant is to receive as his or her Retirement Benefit, the Participant may elect an alternative form of benefit payment in accordance with the following requirements:

(i) A Participant who is married on his or her Benefit Commencement Date (or any Deferred Benefit Commencement Date in effect for him or her in accordance with the provisions of Section 3.3) may elect to receive his or her Retirement Benefit in the form of the Qualified Joint and Survivor Annuity, provided such election is made in accordance with the applicable requirements of subparagraph (iii) below.

(ii) A Participant, whether or not married on his or her Benefit Commencement Date (or any Deferred Benefit Commencement Date in effect for him or her in accordance with the provisions of Section 3.3), may elect to receive his or her Retirement Benefit in the form of the Ten Year Certain and Life Option, provided such election is made in accordance with the applicable requirements of subparagraph (iii) below.

(iii) Provided the Qualified Joint and Survivor Annuity and the Ten Year Certain and Life Option are each the Actuarial Equivalent of the Single Life Annuity payable to the Participant hereunder, the Participant may elect either alternative form of payment by filing the appropriate election form with the Committee at any time prior to the Benefit Commencement Date or Deferred Benefit Commencement Date in effect for such Participant. In the event that either the Qualified Joint and Survivor Annuity or the Ten Year Certain and Life Option is not the Actuarial Equivalent of the Single Life Annuity payable to the Participant hereunder, then the Participant’s election of the form of payment which is not such an Actuarial Equivalent shall be subject to the following limitations:

7

(iv) For purposes of determining whether the Qualified Joint and Survivor Annuity is the Actuarial Equivalent of the Single Life Annuity payable to the Participant, any subsidy provided with respect to the Qualified Joint and Survivor Annuity shall not be taken into account, provided the annual lifetime benefit payable thereunder to the Participant is not greater than his or her annual lifetime benefit under the Single Life Annuity, and the annual lifetime benefit payable to the survivor is not greater than the annual lifetime benefit payable to the Participant under such Qualified Joint and Survivor Annuity. In no event will the Qualified Joint and Survivor Annuity or the Ten Year Certain and Life Option be deemed for purposes of subparagraph (iii) above to be the Actuarial Equivalent of the Single Life Annuity payable to the Participant hereunder, if the scheduled date for the first annuity payment under such alternative form of payment is other than the Benefit Commencement Date or Deferred Benefit Commencement Date in effect at the time for the Participant.

(v) A benefit election made under this Paragraph 3.4 by a Participant who is married on such date is not subject to spousal consent.

3.5 Ten Year Certain and Life Option. A Participant who elects the Ten Year Certain and Life Option shall receive his or her Retirement Benefit in the form of a monthly annuity over his or her lifetime. If the Participant dies before one hundred and twenty (120) monthly payments (hereinafter referred to as the “period certain”) have been made, the Participant’s designated Beneficiary or Beneficiaries shall be entitled to share equally in the Participant’s monthly retirement benefit for the remainder of such period certain. A Participant electing to receive his or her Retirement Benefit in such form must designate, as described in Section 3.6, one or more Beneficiaries to receive any remaining payments under the Plan after his or her death. If the Participant and the designated Beneficiary or Beneficiaries die within the period certain, the remaining payments shall be made to the estate of the designated Beneficiary who last received a payment under this Section 3.5.

3.6 Beneficiary Designation. The Beneficiary designation of a Participant who elects to receive his or her Retirement Benefit in the form of a Ten Year Certain and Life Option shall be made on a form prepared by, and delivered to, the Committee prior to the Benefit Commencement Date or Deferred Benefit Commencement Date in effect for that benefit. The Participant may revoke or change the designation at any time prior to the applicable Benefit Commencement Date by delivering a subsequent form to the Committee.

3.7 Calculation of Alternative Forms of Benefits. The amount of all benefit payment forms specified in Section 3.4 shall be determined in accordance with the provisions of the San Jose Water Company Retirement Plan.

3.8 Retiree Increases.

(a) 1998 Retiree Benefit Increase. Subject to a ten percent (10%) maximum benefit increase, the monthly pension of each Participant (or Beneficiary in the case of a deceased Participant) shall be increased 0.138889% for each month or partial month which has elapsed from the date of the initial payment of retirement benefits to each Participant (or Beneficiary), up to and including February 28, 1998.

8

(b) 2002 Retiree Benefit Increase. Subject to a ten percent (10%) maximum benefit increase, the monthly pension of each Participant (or Beneficiary in the case of a deceased Participant) shall be increased 0.212766% for each month or partial month which has elapsed from (i) the later of the date of the initial payment of benefits or March 1, 1998 to (ii) January 31, 2002.

3.9 Qualified Preretirement Survivor Annuity. If a married Participant dies after his or her Retirement Benefit has vested but before the Benefit Commencement Date or Deferred Benefit Commencement Date in effect for such benefit, then the Participant’s surviving spouse will be entitled to a Qualified Preretirement Survivor Annuity in accordance with this Section 3.9.

(a) The Qualified Preretirement Survivor Annuity will become payable on the later of (1) the first day of the month coinciding with or next following the Participant’s death or (2) the earliest date on which the Participant would have been eligible to receive a Qualified Joint and Survivor Annuity under the Plan (disregarding any Deferred Benefit Commencement Date election the Participant may have outstanding under Section 3.3 at the time of his or her death).

(b) The Qualified Preretirement Survivor Annuity will be in a dollar amount equal to fifty percent (50%) of the amount the Participant would have received had his or her Separation from Service occurred on the day before his or her death and he or she had elected the Qualified Joint and Survivor Annuity as his or her form of benefit payment. In the case of a vested Participant who dies on or before the earliest date on which he or she would have been eligible to receive a Qualified Joint and Survivor Annuity, the amount of the Qualified Preretirement Survivor Annuity will be computed as though the Participant had survived until he or she was first eligible to receive a Qualified Joint and Survivor Annuity, retired at that time with an immediate Qualified Joint and Survivor Annuity, and died the next day.

3.10 Death Benefit. If a Participant who is unmarried at the time dies after his or her Retirement Benefit has vested but before the Benefit Commencement Date or Deferred Benefit Commencement Date in effect for such benefit, then such Participant’s Beneficiary shall be entitled to a Death Benefit in accordance with this Section 3.10.

(a) The Death Benefit will become payable on the later of (1) the first day of the month coinciding with or next following the Participant’s death or (2) the earliest date on which the Participant would have been eligible to receive his or her Retirement Benefit (disregarding any Deferred Benefit Commencement Date election the Participant may have outstanding under Section 3.4 at the time of his or her death).

(b) The Death Benefit will be in a monthly dollar amount equal to the monthly retirement benefit the Participant would have received under the Plan had his or her Separation from Service occurred on the day before the Participant’s death and he or she had elected to receive the optional form of benefit described in Section 3.5 of the Plan. In the case of

9

a vested Participant who dies on or before the earliest date that such Participant would have been eligible to receive his or her Retirement Benefit, the amount of the Death Benefit will be computed as though the Participant had survived until he or she was first eligible to receive a retirement benefit, retired at that time and elected to receive the optional form of benefit described in Section 3.5 of the Plan, and died the next day.

3.11 Adjustments to Benefits. The benefit calculated in accordance with the provisions of this Article III shall, with respect to each Participant referenced in Exhibit A, be subject to the specific adjustments set forth in Exhibit A with respect to that Participant.

3.12 Mandatory Deferral of Payments. Notwithstanding any provision to the contrary in this Article III or any other article in the Plan, a vested Participant’s Retirement Benefit shall not commence under this Plan prior to the earlier of (i) the first day of the seventh (7th) month following the date of his or her Separation from Service or (ii) the date of his or her death, if the Participant is deemed at the time of such Separation from Service to be a Specified Employee and such delayed commencement is otherwise required in order to avoid a prohibited distribution under Code Section 409A(a)(2). Upon the expiration of the applicable deferral period, all monthly retirement payments deferred pursuant to this Section 3.12 shall be paid in a lump sum to the Participant, and the remaining monthly retirement payments due under the Plan shall be paid in accordance with the normal payment dates specified for them herein.

IV. VESTING

4.1 Normal Vesting. A Participant shall vest in his or her Accrued Benefit upon completion of Years of Service as follows:

4.2 Change in Control Severance Vesting. Notwithstanding Section 4.1, a Participant’s Accrued Benefit shall immediately become 100% vested if such Participant becomes entitled to a severance benefit under the Executive Severance Plan by reason of a qualifying termination of his or her Employee status thereunder.

V. FUNDING NATURE OF THE PLAN

The funds used for payment of benefits under this Plan and of the expenses incurred in the administration thereof shall, until such actual payment, continue to be a part of the general funds of the Company, and no person other than the Company shall, by virtue of this Plan, have any interest in any such funds. Nothing contained herein shall be deemed to create a trust of any kind or create any fiduciary relationship. To the extent that any person acquires a right to receive payments from the Company under this Plan, such right shall be no greater than the right of any unsecured general creditor of the Company. The foregoing notwithstanding, the Company may fund the Plan with Board approval at any time, and the Company shall in the

10

event of a Change in Control arrange for the funding, immediately before the effective date of that Change in Control, of all the Accrued Benefits under the Plan through a trust which satisfies the requirements of Revenue Procedure 92-64 and/or such other statutory or regulatory requirements as are necessary to assure that Participants are not subject to Federal income taxation on either their Accrued Benefits or amounts contributed to such trust before their receipt of such benefits or assets.

VI. ADMINISTRATION OF THE PLAN

6.1 The Plan shall be administered by the Committee. The Committee shall have the exclusive authority and responsibility for all matters in connection with the operation and administration of the Plan. The Committee’s powers and duties shall include, but shall not be limited to, the following: (a) selecting the Eligible Employees who are to participate in the Plan, (b) responsibility for the compilation and maintenance of all records necessary in connection with the Plan; (c) determining the amount (if any) of the benefits payable under the Plan to a Participant or his or her spouse or Beneficiary and authorizing the payment of all benefits under the Plan as they become due and payable under the Plan; (d) reducing or otherwise adjusting amounts payable under the Plan if payments are made in error; and (e) authority to engage such legal accounting and other professional services as it may deem proper. Decisions by the Committee shall be final and binding upon all parties.

6.2 The Committee, from time to time, may allocate to one or more of its members (or to any other person or persons or organizations) any of its rights, powers, and duties with respect to the operation and administration of the Plan. Any such allocation shall be reviewed from time to time by the Committee and shall be terminable upon such notice as the Committee, in its sole discretion, deems reasonable and prudent under the circumstances.

6.3 The members of the Committee shall serve without compensation, but all benefits payable under the Plan and all expenses properly incurred in the administration of the Plan, including all expenses properly incurred by the Committee in exercising its duties under the Plan, shall be borne by the Company.

VII. AMENDMENTS AND TERMINATION

7.1 The Board of Directors reserves the power at any time to terminate this Plan and to otherwise amend any portion of the Plan other than this Article VII; provided, however, that no such action shall (i) reduce any Accrued Benefit (or any benefit hereunder based thereon) as of the date of such action or (ii) adversely affect a Participant’s right to continue to vest in such Accrued Benefit in accordance with the terms of the Plan in effect immediately prior to such action.

7.2 Notice of termination or amendment of the Plan, pursuant to Section 7.1, shall be given in writing to each Participant and beneficiary of a deceased Participant.

7.3 No amendment or termination of the Plan shall affect or modify the benefit commencement date provisions or form of payment provisions in effect under Article III immediately prior to such amendment or termination, and such amendment or termination shall not result in any accelerated payment of the retirement benefits accrued under the Plan.

EXHIBIT A

THE EXECUTIVE SUPPLEMENTAL RETIREMENT PLAN

(a) In computing John Weinhardt’s benefit under Section 3.1 of the Plan, he shall receive an additional eight and one quarter tenths of one percent (0.825%) of Final Average Compensation for each year of service as President and Chief Executive Officer of the Company. In addition, Mr. Weinhardt shall be entitled to a supplemental benefit of payment of $225,000, which shall be fully vested upon his retirement and payable in equal monthly installments over the thirty-six (36) month period beginning August 1, 2002 and ending July 31, 2005.

(b) If Barbara Y. Nilsen retires on March 1, 1998, then the benefit to which she is entitled under Sections 3.1 and 3.2 of the Plan shall be increased by $40,000 in the first year, $30,000 in the second year, and $20,000 in the third year of retirement.

(c) In computing Frederick Meyer’s benefit under Sections 3.1 and 3.2 of the Plan, he shall receive an additional two and one-half (2 ¹/2) Years of Service credit and shall be deemed to be 2 ¹/2 years of age older at the time he retires.

(d) In computing the benefits under Article III for any Participant who becomes entitled to a severance benefit under the Executive Severance Plan by reason of a qualifying termination of Employee status after a Change in Control, such Participant shall be credited with an additional number of Years of Service and years of age equal to the number of years of cash severance benefits to which such Participant is entitled under the Severance Plan (or if the severance benefit is paid in a lump sum, the number of years of salary or compensation on which such lump sum severance payment is based). In no event, however, shall any benefit be payable hereunder earlier than it otherwise would have been paid in the absence of such additional Years of Service and age credits.

(e) If W. Richard Roth terminates Employee status before his Normal Retirement Date, the benefit to which he is entitled under Section 3.2 of the Plan shall be the full annual amount computed in accordance with Section 3.1 of the Plan, without any reduction for early commencement of benefits. In addition, in computing Mr. Roth’s Final Average Compensation for purposes of computing his benefit under Article III, the amount of his annual cash performance bonus for each year on and after 2003 shall be deemed to be the greater of his actual bonus for that year or his target bonus for such year, with the applicable amount to be taken into account as Compensation in the month in which the bonus for that year is paid to him or would have been paid to him in the absence of his deferral election or other deferred payment provision applicable to such compensation. Any deferred portion of the bonus shall not again be taken into account as Compensation in the month in which that deferred portion is actually paid. If Mr. Roth becomes entitled to a severance benefit under the Executive Severance Plan by reason of a qualifying termination of Employee status after a Change in Control, he shall be credited with such additional service and years of age, if any, as is necessary, after application of paragraph (d) above, to qualify him for benefits that would be payable had he terminated Employee status after qualifying for an Early Retirement Date, provided that no benefit shall be payable before his actual 55^th birthday.
