                            SIXTEENTH AMENDMENT TO

                    THE UTILITY EMPLOYEES' RETIREMENT PLAN

          The Utility Employees' Retirement Plan (the "Plan") was established on
December 30, 1957, effective as of December 31, 1957, by Suburban Water Systems,
a California corporation, as a mandatory contributory money purchase plan and
trust for the exclusive benefit of participating employees of Suburban Water
Systems.  It was amended on November 12, 1958, December 21, 1959, April 20,
1960, April 26, 1968 and October 10, 1968.  The Sixth Amendment to the Plan,
effective December 31, 1972, restated the Plan and converted it into a non-
contributory defined benefit pension plan.  The Plan has since been amended on
December 22, 1976, June 10, 1978, June 25, 1979, twice on March 26, 1986, by a
"model amendment" adopted on October 20, 1989, and on December 11, 1990,
December 12, 1996, October 30, 1997 and August 5, 1999.

          The Plan is maintained by Southwest Water Company, Suburban Water
Systems, New Mexico Utilities, Inc. and East Pasadena Water Company for the
benefit of their eligible employees.

          The Plan will be terminated effective as of December 30, 1999, and
benefit accruals under the Plan will cease as of December 30, 1999.  In order to
amend the Plan to comply with changes to the Internal Revenue Code made by the
Uniformed Services Employment and Reemployment Rights Act of 1992, the Small
Business Job Protection Act of 1996, the Taxpayer Relief Act of 1997, and the
Internal Revenue Service Restructuring and Reform Act of 1998, and make certain
other changes to the Plan, prior to the termination of the Plan, this Sixteenth
Amendment to the Plan has been adopted by the Board of Directors of Southwest
Water Company, effective as of December 30, 1999, except as otherwise provided
herein.

          1.   Section 1.3 of the Plan is hereby amended to read in its entirety
as follows:

     Section 1.3 - Actuarial Equivalent
     -----------   --------------------

               (a)  "Actuarial Equivalent" shall mean the equivalent of a given
      Benefit or a given amount payable in another manner or by other means,
      determined by or under the direction of the Administrator in accordance
      with the actuarial assumptions prescribed in this Section and actuarial
      principles and methods which are found to be appropriate by the Enrolled
      Actuary, acting independently of the Administrator or the Companies and in
      the exercise of his sole professional judgment (and which principles,
      methods and assumptions may differ from those used for the purposes of
      Section 3.1).  Such principles, methods and assumptions, however, shall be
      reasonable in the aggregate and shall constitute the Enrolled Actuary's
      best estimate of anticipated experience under the Plan.  On such basis,
      the "Actuarial Equivalent" of a Benefit payable as a monthly payment to an
      annuitant on the first day of each calendar
<PAGE>

      month and ending on the calendar month in which the death of such
      annuitant occurs, shall mean such Benefit, multiplied by the actuarial
      equivalency factor determined as follows:

                         (i)  in the case of a distribution, other than a lump
               sum distribution under Section 4.7, 4.8, 4.9 or 4.13, the
               actuarial equivalency factor determined by

                              a  an interest assumption of 7 1/2%, and
                              -

                              b  the UP-84 Mortality Table (with no setback for
                              -
                    Participants and a three year setback for Spouses and/or
                    Beneficiaries), and

                         (ii) in the case of a lump sum distribution under
               Section 4.7, 4.8, 4.9 or 4.13, the actuarial equivalency factor
               determined by

                              a  an interest assumption equal to the Applicable
                              -
                    Interest Rate (as defined in subsection (c)) with respect to
                    such distribution, and

                              -
                    subsection (c)) with respect to such distribution.

                    (b)  Notwithstanding subsection (a), for the purposes of any
      determination under Section 4.12, the "Actuarial Equivalent" of a given
      amount, and the adjustments in the limitation under Section 4.12(a)(i),
      shall be determined as is prescribed in regulations promulgated by the
      Secretary under Code Section 415(b), as follows:

                         (i)  for purposes of determining, with respect to any
               Benefit, the "Actuarial Equivalent" of a straight life annuity in
               an annual amount determined under Section 4.12(a), in accordance
               with the provisions of Code Section 415(b)(2)(B), such "Actuarial
               Equivalent" shall be the amount determined using the lesser of
               the actuarial equivalency factor determined under subsection (a),
               and the actuarial equivalency factor determined by

                              a  an interest assumption of 5%; provided,
                              -
                    however, that, in the case of a lump sum distribution under
                    Sections 4.7, 4.8, 4.9 or 4.13, the Applicable Interest Rate
                    (as defined in subsection (c)) with respect to such
                    distribution shall be substituted for 5%, and

                              b  the Applicable Mortality Table (as defined in
                              -
                    subsection (c)) with respect to such distribution,

               Section 4.12(a)(i), in accordance with the provisions of Code
               Section 415(b)(2)(C), in

               limitation applicable to distributions commencing at Social
               Security Retirement Age, reduced to the age at which the
               distribution commences using factors that are consistent with the
               factors used to reduce old-age insurance benefits under the
               Social Security Act, which factors are presently

                              a  5/9 of 1% for each of the first 36 months by

                    which the distribution commences before the month in which
                    the Participant or Former Participant attains Social
                    Security Retirement Age, and

                              b  5/12 of 1% for each additional month (up to 24
                              -
                    months) by which such distribution commences before the
                    month in which the Participant or Former Participant attains
                    Social Security Retirement Age,

                        (iii) for purposes of determining any limitation under

               determined using the lesser of the actuarial equivalency factor
               determined by the early reduction factors under Section 4.5(b)(i)
               (to the extent applicable), and the actuarial equivalency factor
               determined by

                              a  an interest assumption of 5%, and

          13.  Section 4.8 of the Plan is hereby amended to read as follows:

     Section 4.8 - Optional Retirement Benefit
     -----------   ---------------------------

               (a)  In lieu of his Vested, Early or Normal Retirement Benefit, a
     Participant or Former Participant may elect, with Spousal Consent, to
     receive an Optional Retirement Benefit. A Participant or Former Participant
     must make such an election in writing in accordance with the Rules of the
     Plan and deliver it to the Administrator prior to his Early or Normal
     Retirement Date (or, in the case of a lump sum distribution under paragraph
     (v), the Annuity Starting Date of such distribution), as the case may be.
     Subject to Section 4.15, the Optional Retirement Benefit of a Participant
     or Former Participant shall be one of

                    (i)   a monthly Benefit, reduced as provided in subsection
          (b), payable during each month of the period of his Early or Normal
          Retirement with the provision that if he dies after his Annuity
          Starting Date, and if his properly designated Contingent Annuitant
          survives him, such Contingent Annuitant shall receive a monthly
          payment beginning on the first day of the calendar month next
          following the Participant's death and ending with the calendar month
          in which the Contingent Annuitant's death occurs, in the same amount
          (or in one-half, two-thirds or three-quarters of that amount as the
          Participant may elect); provided, however, that this election shall
          not take effect if the Contingent Annuitant does not survive until the
          Participant's Annuity Starting Date,

                    (ii)  a monthly Benefit, reduced as provided in subsection
          (b), payable during each month of the period of his Early or Normal
          Retirement
<PAGE>

          with the provision that if he dies after his Annuity Starting Date and
          before receiving thirty-six, sixty or one hundred-twenty monthly
          payments, as the Participant may elect, his Beneficiaries as
          designated for this purpose under Section 4.14 will receive the
          remainder of such monthly payments,

                    (iii) solely with respect to a Participant or Former
          Participant who elects to retire on his Early Retirement Date, monthly
          payments increased before the then anticipated commencement date of
          his old age benefits under the federal Social Security Act and
          decreased or, if necessary, eliminated after such date in order to
          provide monthly payments to the Participant which, when added to his
          then anticipated old age benefits under said Act would provide monthly
          payments for his life which are as nearly uniform as possible,

                    (iv)  solely with respect to a Participant or Former
          Participant who has an Account, the amount of his Account in cash in a
          lump sum Benefit and the remainder of his Benefit, as actuarially
          determined under Section 1.3, in accordance with Sections 4.3, 4.5,
          4.6, 4.7 or this Section as applicable, or

                    (v)   a lump sum Benefit pursuant to the termination of the
          Plan, determined as provided in subsection (b), payable as of an
          Annuity Starting Date after the termination of the Plan as follows:

                          a   in the case of a Participant who is an Employee
                          -
               on his Annuity Starting Date (other than a Participant who is
               employed by East Pasadena Water Company), such lump sum
               distribution shall be made in the form of an elective transfer of
               such Participant's lump sum Benefit from the Plan to The 401(k)
               Retirement and Savings Plan for Southwest Water Company (the
               "Southwest Savings Plan") in accordance with subsection (f), or

                          b   in the case of any other Participant or Former
                          -
               Participant, in the form of a lump sum distribution to such
               Participant or Former Participant;

          provided, however, that any lump sum distribution under paragraph (v)
          shall be made in accordance with the Code and ERISA.

               (b)  A Participant's or Former Participant's Optional Retirement
      Benefit (other than a lump sum distribution under paragraph (a)(v)) shall
      be the Actuarial Equivalent of his Vested, Early or Normal Retirement
      Benefit, said Equivalent being computed as of his Early or Normal
      Retirement Date, whichever is applicable.  A Participant's or a Former
      Partnership's Optional Retirement Benefit distributed in the form of a
      lump sum distribution under paragraph (a)(v) shall be the Actuarial
      Equivalent of his Normal Retirement Benefit, such Actuarial Equivalent
      being computed as of the Annuity Starting Date of such distribution.

<PAGE>

               (c)  Notwithstanding any other provision of this Section, no
      Optional Retirement Benefit shall be provided under which any Beneficiary
      or Contingent Annuitant (other than the Participant's or Former
      Participant's spouse or incompetent child) can receive a Benefit having an
      Actuarial Equivalent on the date such Benefits commence greater than the
      then present Actuarial Equivalent of the Participant's Benefit under said
      election.

               (d)  Notwithstanding subsection (a) and Section 4.7(g), if a
      Participant or Former Participant elects to receive any one of the
      Optional Retirement Benefits specified in paragraph (a)(i) and his
      Contingent Annuitant is his Spouse, Spousal Consent shall not be required.

               (e)  Notwithstanding anything in this Section to the contrary, a
      Participant or Former Participant who is eligible to elect a lump sum
      distribution under paragraph (a)(v) may elect to receive, in lieu thereof,
      the Actuarial Equivalent of his Vested, Early or Normal Retirement Benefit
      (whichever is greatest) in the form of a monthly payment on the first day
      of each calendar month commencing on or after the Annuity Starting Date on
      which such lump sum distribution is otherwise payable and ending on the
      calendar month in which his death occurs, or, if required under Section
      4.7, in the form of a Joint and Survivor Annuity.

               (f)  If a Participant elects to receive lump sum distribution
      under subparagraph 4.8(a)(v)a, such lump sum distribution shall be made in
                                  -
      the form of an elective transfer of such Participant's lump sum Benefit
      from the Plan to the Southwest Savings Plan in accordance with Treasury
      Regulation Section 1.411(d)-4 Q/A-3(b).  Such Participant's lump sum
      Benefit as of his Annuity Starting Date shall be transferred in a transfer
      of assets and liabilities from the Plan to the Southwest Savings Plan
      satisfying the requirements of Code Sections 401(a)(12) and 414(l),
      Treasury Regulation Section 1.414(l)-1 and ERISA Section 208.  Upon such
      transfer, the Trustees shall transfer from the Trust an amount, in cash,
      equal to the amount of such Participant's lump sum Benefit as of the
      Annuity Starting Date to the trust established pursuant to the Southwest
      Savings Plan.  Such lump sum distribution shall be conditioned upon the
      voluntary, fully informed election by the Participant of the transfer of
      such Participant's lump sum Benefit to the Southwest Savings Plan.  Such
      lump sum distribution shall only be made if such Participant has elected
      not to receive a life annuity or a Joint and Survivor Annuity in
      accordance with subsection 4.7(e) and has elected such lump sum
      distribution with Spousal Consent.  Such lump sum distribution shall be
      credited to an account under the Southwest Savings Plan and such
      Participant shall be fully vested in the amount credited to such account.
      The amount credited to such account shall be distributable under the terms
      of the Southwest Savings Plan.

          14.  Section 4.13(a) of the Plan is hereby amended to read in its
entirety as follows:

<PAGE>

               (a)  Notwithstanding any other provision of the Plan to the
      contrary, upon a Participant's Separation from the Service, or following

      or on his account the Actuarial Equivalent in cash of his Vested, Normal
      or Early Retirement Benefit if it is not more than $5,000 (and at no time
      exceeded such amount at the time of a prior distribution under Section
      4.15(a)).

          15.  Effective as of December 30, 1995, Article IV of the Plan is
hereby amended by adding Section 4.18 as follows at the end thereof:

      the Plan has a "liquidity shortfall" (as defined in Code Section
      401(a)(32)(C)).

          under a single life annuity (plus any Social Security supplements
          described in the last sentence of Code Section 411(a)(9)), to a
          Participant, Former Participant, Beneficiary or Contingent Annuitant

      Beneficiary or Contingent Annuitant to the Pension Benefit Guaranty
      Corporation, or by purchasing irrevocable commitments from an insurer with
