To the Purchaser named in

         Reference  is hereby made to that certain  Note  Agreement  dated as of

shall have the same  meaning as specified  in the Note  Agreement.  Reference is
further made to Section 4.3 thereof which requires  that,  prior to the delivery
of any Additional Notes, the Company and each Additional Purchaser shall execute
and deliver a Supplement.

         The Company hereby agrees with the Purchaser named on Schedule A hereto
as follows:

shall be substantially in the form set out in Exhibit 1 hereto with such changes
therefrom, if any, as may be approved by the Purchaser and the Company.

         2. Subject to the terms and  conditions  hereof and as set forth in the
Note  Agreement  and  on  the  basis  of  the   representations  and  warranties

of [Bank of America, ABA No. 121000358,  Account No. 14879-00161,  Account Name:
California Water Service Company Security Sales],  in the amount of the purchase
price at 11:00 A.M.,  San  Francisco,  California  time,  on May 1, 2003 or such
later date (not later than May 7, 2003) as shall  mutually be agreed upon by the
Company and the Purchaser of the Series I Notes (the "Closing Date").

         4. Prepayment of Notes.

         (a)  Required  Prepayments.  On May 1,  2013 and on May 1 of each  year
thereafter  to and including  May 1, 2022,  the Company will prepay  $909,090.91
principal  amount (or such lesser principal amount as shall then be outstanding)
of the Series I Notes at par and without payment of the Make-Whole Amount or any
premium,  provided that upon any partial prepayment permitted by Section 4(b) or
4(c),  the principal  amount of each  required  prepayment of the Series I Notes
becoming due under this Section 4(a) on and after the date of such prepayment or
purchase  shall  be  reduced  in the same  proportion  as the  aggregate  unpaid
principal amount of the Series I Notes is reduced as a result of such prepayment
or purchase.  No other  prepayments  are required to be made with respect to the
Series  I  Notes  prior  to the  expressed  maturity  date  thereof  other  than
prepayments  made in  connection  with an  acceleration  of the  Series  I Notes
pursuant to the provisions of Section 6.3 of the Note Agreement.

         (b) Optional Prepayment with Premium. Upon compliance with Section 4(d)
below the Company shall have the  privilege,  at any time and from time to time,
of prepaying  the  outstanding  Notes of any Series,  either in whole or in part
(but if in part then in a minimum  principal  amount of  $100,000) by payment of
the  principal  amount of the Notes of such  Series,  or  portion  thereof to be
prepaid,  and accrued interest thereon to the date of such prepayment,  together
with a premium equal to the  Make-Whole  Amount,  determined as of five Business
Days prior to the date of such prepayment pursuant to this Section 4(b).

         (c) Optional  Prepayment  at Par in the Event of  Condemnation.  In the
event a Material  Condemnation  shall have occurred with respect to any property
of the Company or a Restricted  Subsidiary,  then upon  compliance  with Section
4(d) below the Company  shall have the privilege of applying the proceeds of any
condemnation award received in connection with such Material Condemnation to the
prepayment of the principal amount of the Notes of any Series then  outstanding,
or any portion  thereof to the extent of such  proceeds,  together  with accrued
interest  thereon to the date of such prepayment.  Any optional  prepayment made
pursuant to this Section 4(c) shall be without premium.

         (d) Notice of Optional Prepayments. The Company will give notice of any
prepayment of the Notes pursuant to Section 4(b) or 4(c) to each Holder of Notes
to be prepaid  not less than 30 days nor more than 60 days before the date fixed
for such optional  prepayment  specifying (a) such date, (b) the Section of this
Seventh  Supplement  under which the prepayment is to be made, (c) the principal
amount of the Holder's  Notes to be prepaid on such date,  (d) whether a premium
may be payable,  (e) the date when the premium, if any, will be calculated,  (f)
the estimated premium,  together with a reasonably detailed  computation of such
estimated  premium,  and (g) the accrued interest  applicable to the prepayment.
Such  notice of  prepayment  shall also  certify  all facts,  if any,  which are
conditions precedent to any such prepayment. Notice of prepayment having been so
given, the aggregate  principal  amount of the Notes to be prepaid  specified in
such notice,  together with accrued  interest  thereon and the premium,  if any,
payable with respect thereto shall become due and payable on the prepayment date
specified  in said  notice.  Not  later  than  two  Business  Days  prior to the
prepayment date specified in such notice,  the Company shall provide each Holder
of a Note to be  prepaid  written  notice of the  premium,  if any,  payable  in
connection

                                       30
<PAGE>

with such  prepayment and,  whether or not any premium is payable,  a reasonably
detailed computation of the Make-Whole Amount.

         (e) Application of Prepayments.  In the case of each partial prepayment
of the Notes  pursuant to the  provisions of Section 4(b) or 4(c), the principal
amount of the Notes of the Series to be prepaid shall be allocated  among all of
the Notes of such Series at the time  outstanding  in  proportion,  as nearly as
practicable, to the respective unpaid principal amounts thereof.

         (f) Direct Payment.  Notwithstanding anything to the contrary contained
in the Note Agreement,  this Seventh Supplement or the Notes, in the case of any
Note owned by any Holder that is a Purchaser,  Additional Purchaser or any other
Institutional  Holder which has given written  notice to the Company  requesting
that  the  provisions  of this  Section  4(f)  shall  apply,  the  Company  will
punctually pay when due the principal thereof,  interest thereon and premium, if
any,  due with  respect to said  principal,  without  any  presentment  thereof,
directly to such Holder at its address set forth herein or such other address as
such Holder may from time to time  designate  in writing to the Company or, if a
bank account with a United  States bank is so  designated  for such Holder,  the
Company  will make such  payments in  immediately  available  funds to such bank
account,  marked for attention as indicated,  or in such other manner or to such
other  account in any United  States  bank as such  Holder may from time to time
direct in writing.

         (g) Make Whole Amount. The term "Make-Whole Amount" means, with respect
to any Series I Note, an amount equal to the excess,  if any, of the  Discounted
Value of the Remaining  Scheduled  Payments with respect to the Called Principal
of such  Note  over the  amount  of such  Called  Principal,  provided  that the
Make-Whole  Amount  may in no event  be less  than  zero.  For the  purposes  of
determining  the  Make-Whole  Amount,  the  following  terms have the  following
meanings:

                  "Called  Principal"  means, with respect to any Series I Note,
         the  principal  of such Note that is to be prepaid  pursuant to Section
         4(b) or has become or is  declared  to be  immediately  due and payable
         pursuant to Section 6.3 of the Note Agreement, as the context requires.

                  "Discounted Value" means, with respect to the Called Principal
         of any Series I Note, the amount  obtained by discounting all Remaining
         Scheduled  Payments  with respect to such Called  Principal  from their
         respective  scheduled due dates to the Settlement  Date with respect to
         such Called Principal,  in accordance with accepted  financial practice
         and at a discount factor (applied on the same periodic basis as that on
         which  interest  on  the  Series  I  Notes  is  payable)  equal  to the
         Reinvestment Yield with respect to such Called Principal.

                  "Reinvestment   Yield"  means,  with  respect  to  the  Called
         Principal  of any  Series I Note,  0.50%,  plus the  yield to  maturity
         implied by (i) the  yields  reported,  as of 10:00 A.M.  (New York City
         time) on the fifth  Business Day  preceding  the  Settlement  Date with
         respect to such Called Principal,  on the display page of the Bloomberg
         Financial Markets Services Screen PX1 or the equivalent screen provided
         by Bloomberg  Financial  Markets  Commodities  News for actively traded
         U.S.  Treasury  securities  having a  maturity  equal to the  Remaining
         Average Life of such Called  Principal as of such  Settlement  Date, or
         (ii) if such  yields  are not  reported  as of such time or the  yields
         reported as of such time are not  ascertainable,  the Treasury Constant
         Maturity  Series  Yields  reported,  for the  latest day for which such
         yields have been so reported as of the second  Business  Day  preceding
         the Settlement Date with respect to such Called  Principal,  in Federal
         Reserve  Statistical  Release H.15 (519) (or any  comparable  successor
         publication)  for actively

                                       31
<PAGE>

         traded U.S. Treasury securities having a constant maturity equal to the
         Remaining  Average Life of such Called  Principal as of such Settlement
         Date.  Such implied  yield will be  determined,  if  necessary,  by (a)
         converting U.S. Treasury bill quotations to  bond-equivalent  yields in
         accordance  with  accepted  financial  practice  and (b)  interpolating
         linearly  between (1) the actively traded U.S.  Treasury  security with
         the maturity closest to and greater than the Remaining Average Life and
         (2) the  actively  traded  U.S.  Treasury  security  with the  maturity
         closest to and less than the Remaining Average Life.

                  "Remaining  Average  Life"  means,  with respect to any Called
         Principal,  the number of years (calculated to the nearest  one-twelfth
         year) obtained by dividing (i) such Called  Principal into (ii) the sum
         of the products obtained by multiplying (a) the principal  component of
         each Remaining  Scheduled Payment with respect to such Called Principal
         by (b) the number of years (calculated to the nearest one-twelfth year)
         that will  elapse  between  the  Settlement  Date with  respect to such
         Called Principal and the scheduled due date of such Remaining Scheduled
         Payment.

                  "Remaining  Scheduled  Payments"  means,  with  respect to the
         Called  Principal  of any Series I Note,  all  payments  of such Called
         Principal and interest  thereon that would be due after the  Settlement
         Date with respect to such Called Principal if no payment of such Called
         Principal  were made prior to its scheduled due date,  provided that if
         such Settlement  Date is not a date on which interest  payments are due
         to be made  under the terms of the  Series I Notes,  then the amount of
         the next succeeding  scheduled  interest payment will be reduced by the
         amount of interest  accrued to such  Settlement Date and required to be
         paid on such Settlement Date pursuant to Section 4(b) hereof or Section
         6.3 of the Note Agreement.

                  "Settlement  Date" means, with respect to the Called Principal
         of any Series I Note, the date on which such Called  Principal is to be
         prepaid pursuant to Section 4(b) hereof or has become or is declared to
         be  immediately  due and  payable  pursuant  to Section 6.3 of the Note
         Agreement, as the context requires.

         5.       Closing Conditions.

         (a) Conditions.  The obligation of the Purchaser to purchase the Series
I Notes on the Closing Date shall be subject to the  performance  by the Company

         Date,  the purchase of the Series I Notes shall (a) be permitted by the
         laws and  regulations  of each  jurisdiction  to which the Purchaser is
         subject,  without recourse to provisions (such as Section 1405(a)(8) of

the Note Agreement, may be cancelled by the Company.

         (c) If on the Closing Date the Company fails to tender to the Purchaser
the  Series  I Notes  to be  issued  to the  Purchaser  on  such  date or if the
conditions specified in Section 5(a) have not been fulfilled,  the Purchaser may
thereupon  elect to be relieved of all further  obligations  under this  Seventh
Supplement.  Without  limiting the  foregoing,  if the  conditions  specified in
Section 5(a) have not been fulfilled,  the Purchaser may waive compliance by the
Company with any such  condition to such extent as the Purchaser may in its sole
discretion determine.  Nothing in this Section 5(c) shall operate to relieve the
Company of any of its obligations  hereunder or to waive the Purchaser's  rights
against the Company.

         6. The Purchaser  represents and warrants that the  representations and
warranties  set forth in Section 3.2 of the Note  Agreement are true and correct
on the date of execution and acceptance of this Seventh  Supplement with respect
to the Series I Notes purchased by the Purchaser.

         7. The Company and the  Purchaser  agree to be bound by and comply with
the terms and  provisions  of the Note  Agreement  as if the  Purchaser  were an
original signatory to the Note Agreement.

                                       Name:  __________________________________

                         REPRESENTATIONS AND WARRANTIES

         The Company represents and warrants to the Purchaser that:

          1. Corporate Organization, Subsidiaries. The Company is duly organized
and existing and in good  standing  under and by virtue of the laws of the State
of  California  and is duly  authorized  and  empowered  to own and  operate its
properties  and to carry on its  business,  all as and in the places  where such
properties  are now owned and  operated  and such  business  is  conducted.  The
Company has no Subsidiaries.

          2.  Corporate  Authority.  The  Company has full  corporate  power and
corporate  authority to sell and issue the Series I Notes. The issuance and sale
of the Series I Notes and the execution  and delivery of the Seventh  Supplement
will have been duly  authorized  by the Board of Directors of the Company and by
the Public  Utilities  Commission of the State of California (the  "Commission")
prior to the Closing  Date,  and no other action is required to be taken by, and
no consents or approvals are required to be obtained from, the  shareholders  of
the Company or any public body or bodies,  and no other corporate  action of the
Company is requisite to such issue and sale.

          3. Business and Property.  The Purchaser has heretofore been furnished
with a copy of the Company  Information which generally sets forth the principal
properties  of the  Company  and  the  business  conducted  and  proposed  to be
conducted by the Company.

          4.  Indebtedness.  Annex A attached  hereto  correctly  describes  all
Current Debt, Funded Debt and Capitalized  Leases of the Company  outstanding on
September 30, 2002.

          5.  Financial  Statements  and Reports.  The Company has furnished the
Purchaser with a copy of its audited  financial  reports for 1999, 2000 and 2001
hereinafter  called  the  "Company  Reports,"  and a copy of Form 10-K  filed by
California Water Service Group ("CWSG")  hereinafter called the "CWSG 10-K" with
the  Securities and Exchange  Commission for 2001,  together with all reports or
documents  required to be filed by CWSG  pursuant to Sections  13(a) or 15(d) of
the  Securities  Exchange Act of 1934, as amended,  since the filing of the CWSG
10-K. The Company has also  furnished the Purchaser with an unaudited  quarterly
financial  statement for the Company for the fiscal quarter ended  September 30,
2002,  and Forms 10 Q for CWSG for the fiscal  quarter ended  September 30, 2002
(the "Quarterly  Reports").  The financial statements contained in the foregoing
Company Reports, the CWSG 10-K, the Quarterly Reports and such other reports and
documents  were  prepared  in  accordance  with  generally  accepted  accounting
principles upon a consistent  basis and are complete and correct and the balance
sheets included therein fairly present the financial condition of the Company or
CWSG, as the case may be, as at the respective  dates thereof and the Statements
of Income,  Common  Shareholders'  Equity and Cash Flows included therein fairly
present the  results of the  operations  of the Company for the periods  covered
thereby,  subject  in the  case  of  unaudited  statements  to  normal  year-end
adjustments.

          6. Material  Contracts.  The Company has no contracts or  commitments,
whether  contingent  or other,  which are material to the Company and which were
not made in the ordinary course of business.  Certain material contracts related
to water  supply are listed in Annex B hereto.  The Company has no  contracts or
commitments,  contingent or other,  which  materially and adversely affect or in
the future may (so far as the  Company can  foresee)  materially  and  adversely
affect the Company or its business,  property,

                                   EXHIBIT 2
                                 (to Supplement)

<PAGE>

assets,  operations or condition,  financial or other.  As of December 31, 2001,
there were no  material  liabilities  of the  Company  (other  than those  under
contracts  entered into in the normal and ordinary course of business),  actual,
contingent or accrued,  which were not reflected in the Company Reports and CWSG
10-K except for (i) liability in respect of uncompleted  construction work under
open contracts in connection  with the Company's  construction  program and (ii)
the  obligations  of the Company to  contribute to a pension plan, an employees'
savings plan and a health and welfare plan.

          7. No  Material  Adverse  Change.  (a) There has been no change in the
condition of the Company,  financial or other,  from that set forth or reflected
in the Company  Information,  other than changes  which may have occurred in the
ordinary course of business or by reason of ordinary  dividends paid or declared
or outstanding  First Mortgage Bonds redeemed by the Company in accordance  with
their terms,  and no such changes in the ordinary  course of business  have been
material adverse changes.

         (b)  Since  December  31,  2001,  neither  the  business,   operations,
properties  nor  assets of the  Company  have  been  adversely  affected  in any
material way by any casualties such as fire, windstorm, riot, strike, explosion,
accident, flood, earthquake,  lockout, sabotage, activities of armed forces, act
of God or the public enemy or  condemnation  of  properties by the United States
government or any municipal governmental agency, authority or body.

          8. Title to  Properties.  The Company is engaged in the  business of a
public utility water company  serving all or a portion of the California  cities
and  communities  listed in the 2001 Company Report and paragraph 9 hereof.  The
Company  has  good  and  merchantable  title,  subject  only to the  lien of the
Mortgage  Indenture  and to current  tax and  assessment  liens,  rights-of-way,
easements  and certain  minor  liens,  encumbrances,  clouds or defects in title
which do not  materially  affect  the use  thereof,  to all the  material  water
distribution  facilities  (including,   without  limitation,   transmission  and
distribution  mains,  pump stations,  wells,  storage tanks and  reservoirs) and
other material units of property used in its business except as follows:

                   (a) some of the offices, but not its principal office, are in
         leased premises and some wells, well sites and other minor distribution
         facilities are rented; and

                   (b) several  wells are located on property  which the Company
         does not own but in which it has an easement  for the  location of such
         wells;

and except as to easements and  rights-of-way  and certain  parcels of land (not
exceeding for said parcels of land an aggregate book value of  $1,000,000)  with
respect to which there is a possibility of reverter if the property ceases to be
used for public utility  purposes,  and,  except that the greater portion of its
transmission and distribution  systems is located in public highways and streets
and in  rights-of-way  owned by the Company over lands of others,  the Company's
title thereto is fee simple. Except for parcels of land having an aggregate book
value of not more than $1,000,000,  the Company has good and merchantable  title
to all its other  property  and assets  subject only to the lien of the Mortgage
Indenture  and the lien of the Dominguez  Mortgage  Indenture and to current tax
and assessment  liens and minor liens and  encumbrances  which do not materially
affect the use thereof.  All of the properties of the Company are located in the
State of California and  substantially all of the properties of the Company used
or useful in its public utility business are subject to the Mortgage  Indenture.
As used  herein,  the  term  "Dominguez  Mortgage  Indenture"  means  the  Trust
Indenture dated as of August 1, 1954, as supplemented from time to time, between
the Company,  as successor to Dominguez  Water  Company  ("Dominguez")  and U.S.
Bank,  as

                                      E-2-2
<PAGE>

Trustee,  which  provides a lien on  properties  owned by Dominguez  immediately
prior  to the  merger  described  in  paragraph  9  hereof  which  lien  secures
$9,000,000 in aggregate  principal  amount of Dominguez bonds which were assumed
by the Company upon the merger.

          9. Franchises.  The Company has, in its judgment,  adequate franchises
and  permits  without  burdensome   restrictions  (other  than  those  typically
contained  in  franchises  and  permits  of this  type) to allow the  Company to
conduct the business in which it is engaged.

         The Company has two classes of  franchises to install and operate water
pipes and mains under public streets and highways:

                   (a) so-called "constitutional"  franchises obtained by virtue
         of the  provisions  of  Article  XI,  Section  19,  of  the  California
         Constitution, as in effect prior to 1911; and

                   (b) franchises granted pursuant to statutory authority.

         The Company  believes,  based on the advice of counsel (which is itself
based upon the assumption of the accuracy of information obtained by the Company
from sources  believed to be reliable  that the  following  cities served by the
Company were all incorporated prior to 1911:

                  Bakersfield        Marysville          South San Francisco
                  Chico              Oroville            Stockton
                  Dixon              Redondo Beach       Visalia
                  Hermosa Beach      Salinas             Willows
                  King City          San Mateo
                  Livermore          Selma

that water  distribution  systems were constructed and service  furnished to the
inhabitants  of each by various  predecessors  of the Company prior to 1911, and
that there were no public water works owned or controlled by the municipality in
any of them prior to 1911), that the Company has a "constitutional" franchise in
each of the above cities and under such constitutional franchise has a perpetual
right which was not  repealed  by the repeal of Article  XI,  Section 19, of the
California  Constitution  to continue to occupy  public  streets of each of said
cities  with its pipes and mains and to lay down  additional  pipes and mains in
said streets for the supplying of water, subject to reasonable regulation by the
respective  municipalities.  The Company also  believes,  based on the advice of
counsel,  that this right is not limited to streets in which pipes or mains were
laid  prior  to  1911  but   extends  at  least  to  all  streets  in  the  said
municipalities  as they  existed  at the date of  repeal  of the  constitutional
provision in 1911 and probably also extends to territory  incorporated into each
respective  city  after such  repeal,  although  this  latter  question  remains
somewhat in doubt in the absence of a final decision of the courts thereon.  The
Company  holds either by assignment or as original  grantee  franchises  granted
under  statutory  authority by the Counties of Kern,  Los Angeles,  San Joaquin,
Santa  Clara and  Monterey,  the  Cities  of  Montebello,  Torrance,  Cupertino,
Sunnyvale, Los Altos, Mountain View, Bakersfield,  Commerce, San Carlos, Rolling
Hills Estates and Thousand  Oaks, and the Towns of Los Altos Hills and Atherton.
Following  incorporation of the City of Rancho Palos Verdes in 1973, the Company
made franchise  payments to the City and the City accepted the same as successor
in interest to the grantor's  rights under the Company's  former  franchise from
the County of Los Angeles; the City has agreed that the Company may exercise its
rights in the City under its current  County  franchise  until the expiration of
that franchise in 2012. The Company's franchises from the Cities of Palos Verdes
Estates,   Menlo  Park  and  Woodside   terminated  in  1977,   1993  and  1994,
respectively.  While  none of the  Cities and the  Company

                                      E-2-3
<PAGE>

have executed a new franchise agreement,  the Company has made and will continue
to make  franchise  payments  to each  of the  Cities  in  accordance  with  the
provisions  of the prior  franchise.  In other  areas  where the  Company has no
franchise, the Company or its predecessors have distributed water for many years
and, to the  Company's  knowledge,  no  question  has ever been raised as to the
right to make such  distribution  and to maintain all pipes and mains  necessary
therefor.

         On May 25,  2000,  Dominguez  Service  Corporation  was merged into the
Company and subsequently  Dominguez and its  subsidiaries  were also merged into
the Company (collectively,  the "merger"). The Company acquired in the Dominguez
merger  operations in the following  cities,  counties,  townships or localities
that Dominguez previously served:

         Bodfish               Kern County         Los Angeles County
         Carson                Kernville           Lucerne
         Compton               Lake Hughes         Mountain Shadows
         Duncans Mills         Lakeland            Onyx
         Fremont Valley        Lancaster           Squirrel Valley
         Guerneville           Leona Valley        Torrance
         Harbor City           Long Beach          Wofford Heights

Water  distribution  systems  were  constructed  and  service  furnished  to the
inhabitants of the localities currently known as Carson,  Compton,  Harbor City,
Long Beach and Torrance by various predecessors of the Company prior to 1911 and
the Company  believes  that it has a prior  right to operate in these  locations
which right was not extinguished by the incorporation of these cities subsequent
to 1911.  Except as noted below,  Dominguez has no franchises  from these cities
and has made no franchise payments to them and, to the Company's  knowledge,  no
question has ever been raised as to the right to make water  distribution and to
maintain all pipes and mains necessary therefor.

         As  to  the  remaining  localities,   Dominguez  has  received  written
franchise  agreements  which  are in full  force  and  effect  and has  paid all
franchise  fees to date,  with the  exception  of Compton and the City of Carson
Redevelopment Project #2, as to which the franchises expired without renewal in,
respectively,  1994 and 1998.  Dominguez  continued to provide water services to
Compton  and the City of  Carson  Redevelopment  Project  #2  subsequent  to the
expiration of the respective  franchises,  and to pay franchise fees, and to the
Company's  knowledge  no  question  has ever been raised as to the right to make
such distribution and to maintain all pipes and mains necessary therefor.

         10.  Condition  of Assets.  The  physical  assets of the Company are in
sound operating  condition,  there are no material arrears in the maintenance of
any such physical assets and the Company  believes that its sources of water are
adequate to meet its requirements for the foreseeable future.

         11. Pending Litigation, Proceedings. (a) There are no actions, suits or
proceedings  pending  at law or in equity or  before or by any  federal,  state,
municipal or other governmental department, commission, board, bureau, agency or
instrumentality,  domestic  or foreign,  or, to the  knowledge  of the  Company,
threatened  against or affecting the Company not adequately covered by insurance
or for  which  reserves  adequate  in  the  Company's  judgment  have  not  been
established  which  involve,  in  the  opinion  of  the  Company,  a  reasonable
possibility of judgments or liabilities  exceeding $500,000 in the aggregate net
of insurance, or which may, in the opinion of the Company result in any material
adverse change in the

                                      E-2-4
<PAGE>

business or properties or in the condition,  financial or other, of the Company,
or the  ability of the  Company to perform  its  obligations  under the  Seventh
Supplement or the Series I Notes.

         (b) There  are no  proceedings  pending  or,  to the  knowledge  of the
Company,  threatened  against the  Company  before or by any  federal,  state or
municipal commission, board or other administrative agency, which materially and
adversely affect the water rates of the Company presently in effect.

         (c) The  Company is not in  default  with  respect to any order,  writ,
injunction  or  decree  of  any  court,  or  any  federal,  state  or  municipal
commission,  board or other  administrative  agency and the Company has complied
with all applicable statutes and regulations of the United States of America and
of any state,  municipality or agency of any thereof,  in respect of the conduct
of its business known or believed by the Company to be applicable  thereto,  the
failure to comply  with which  could  reasonably  be expected to have a material
adverse effect on the Company or its properties.

         12. No  Condemnation  Proceedings.  Since January 1, 1995, no elections
have  been  held  or  other  actions  taken   authorizing  the  commencement  of
proceedings for  condemnation of any of the properties of the Company.  However,
from time to time  there are  expressions  of  interest  made by public  bodies,
elected or appointed municipal officials,  persons seeking political position or
citizens groups urging acquisition of the Company's facilities in one or more of
the  communities  served by the  Company.  The Company does not believe that any
acquisition  by a city or  municipality  of its  properties by  condemnation  or
threat thereof would be adverse to the holder of the Series I Notes.

         13. No  Burdensome  Restrictions.  The  Company  is not  subject to any
burdensome corporate  restrictions in its Articles of Incorporation,  By-Laws or
otherwise, which materially and adversely affect or in the future may (so far as
the Company can  foresee)  materially  and  adversely  affect the Company or its
business, property, assets, operations or condition, financial or other.

         14. Regulatory  Status,  Approval.  (a) The Company is not a registered
holding company or a subsidiary of a registered  holding company and the Company
is not  required to register  under the Public  Utility  Holding  Company Act of
1935, as amended. The Company is subject to the jurisdiction of the Commission.

         (b) No consent of, approval or authorization by, filing or registration
with, or notice to any  governmental  or public  authority or agency is required
for the  issuance,  sale or  delivery  of the  Series I Notes or the  execution,
delivery or performance of the Seventh Supplement,  other than the authorization
of the Commission,  which authorization has been duly obtained, is in full force
and effect and is not subject to any appeal, hearing,  rehearing or contest. All
conditions  contained in any such authorization which were to be fulfilled on or
prior to the issuance of the Series I Notes have been fulfilled. The Company has
furnished  to your special  counsel  true,  correct and complete  copies of said
authorization  and all  applications  heretofore  filed with or submitted to the
Commission in connection with its action to obtain said authorization.

         15. No Defaults,  Compliance with Other Instruments. The Company is not
in default under any outstanding  indentures,  contracts or agreements which are
material to the Company including,  without limitation,  the Mortgage Indenture;
and on the  Closing  Date there will not exist any  condition  which  would be a
default  under any such  indenture,  contract or  agreement.  The  execution and
delivery of the Seventh Supplement, the consummation of the transactions therein
provided for and compliance  with the  provisions

                                      E-2-5
<PAGE>

of the Seventh Supplement and the Series I Notes by the Company will not violate
or result in any breach of the terms, conditions or provisions of, or constitute
a default  under,  its  Articles  of  Incorporation,  By-Laws or any  indenture,
mortgage,  deed of  trust,  bank  loan or credit  agreement,  or other  material
agreement or  instrument to which the Company is a party or by which the Company
may be bound,  nor will such acts result in the violation of any applicable law,
rule, regulation or order applicable to the Company of any court or governmental
authority  having  jurisdiction in the premises or in the creation or imposition
of any lien, charge or encumbrance of any nature  whatsoever,  upon any property
or assets of the Company.

         16. Leases.  The Company has the right to, and does, enjoy peaceful and
undisturbed possession under all material leases to which it is a party or under
which it is operating.  All such leases are valid,  subsisting and in full force
and effect, and the Company is not in default under any thereof and no event has
occurred  and is  continuing,  and no  condition  exists  that,  after notice or
passage of time or both could become a material default under any such Lease.

         17. Use of Proceeds.  The Company will use the gross  proceeds  derived
from the sale of the Series I Notes under the Seventh  Supplement  to  refinance
existing  Indebtedness.  None of the  transactions  contemplated  in the Seventh
Supplement (including,  without limitation thereof, the use of the proceeds from
the sale of the Series I Notes) will violate or result in a violation of Section
7 of the Securities  Exchange Act of 1934, as amended, or any regulations issued
pursuant thereto,  including without  limitation,  Regulations U, T and X of the
Board of Governors of the Federal  Reserve  System,  12 C.F.R.,  Chapter II. The
Company  does not own or intend to carry or purchase any "margin  stock"  within
the meaning of said Regulation U, including  margin stock  originally  issued by
it.  None of the  proceeds  from the sale of the  Series I Notes will be used to
purchase or carry (or refinance any borrowing the proceeds of which were used to
purchase or carry) any margin stock.

         18. ERISA.  (a) The fair market value of all assets under all "employee
pension  benefit  plans" (as such term is  defined  in  Section  3(2) of ERISA),
maintained  by the  Company,  as from  time to time in  effect,  exceeded  as of
December 31, 2001, the last annual  valuation date, the actuarial  present value
of all benefits vested under the Plans by more than $10,898,000.

         (b) Neither any of the Plans nor any of the trusts created  thereunder,
nor  any  trustee  or  administrator  thereof,  has  engaged  in  a  "prohibited
transaction,"  as such term is defined in Section  4975 of the Code which  could
subject  the  Plans  or  any  of  them,  any  such  trust,  or  any  trustee  or
administrator  thereof,  or any disqualified person with respect to the Plans to
the tax or penalty on  prohibited  transactions  imposed by said  Section  4975,
except  that,  with  respect to any  actions  or  omissions  of  administrators,
trustees,  other fiduciaries,  parties in interest or disqualified persons of or
in respect to the Plans (other than  employees of the Company),  the Company has
no knowledge  that any of such persons has  committed a prohibited  transaction,
nor has the Company participated knowingly in or knowingly undertaken to conceal
a prohibited  transaction with or by any of such persons nor enabled any of them
to commit a prohibited transaction.

         (c)  Neither  any of the  Plans  subject  to Title IV of ERISA  nor any
trusts  related  to such  plans  have been  terminated,  nor have there been any
Reportable Events, as that term is defined in Section 4043 of ERISA (as modified
by the  regulations  thereunder),  in respect of those plans since the effective
date of ERISA.

                                      E-2-6
<PAGE>

         (d)  Neither any of the Plans which are subject to Section 302 of ERISA
nor any trusts  related to such plans have  incurred  any  "accumulated  funding
deficiency,"  as such  term is  defined  in said  Section  302  (whether  or not
waived), since the effective date of ERISA.

         (e) The  consummation of the  transactions  provided for in the Seventh
Supplement  and  compliance by the Company with the  provisions  thereof and the
Series I Notes issued  thereunder  will not involve any  prohibited  transaction
within the meaning of ERISA or Section 4975 of the Code.

         19. Taxes. All Federal,  state and local taxes and assessments due from
the Company have been (a) fully paid or adequately  provided for on the books of
the Company in accordance with generally accepted  accounting  principles or (b)
are being contested in good faith by the Company.  There has been no examination
of the Federal income tax returns of the Company by the Internal Revenue Service
subsequent to the examinations of the returns for tax years 1984-1991.

         20. Compliance with Laws. To the best of the Company's knowledge, after
due inquiry, the Company is in compliance with all applicable Federal, state, or
local laws, statutes, rules, regulations or ordinances relating to public heath,
safety or the environment,  including, without limitation, relating to releases,
discharges,  emissions or disposals to air, water,  land or ground water, to the
withdrawal  or use of  ground  water,  to  the  use,  handling  or  disposal  of
polychlorinated  biphenyls  (PCB's),  asbestos  or  urea  formaldehyde,  to  the
treatment,  storage,  disposal or management of hazardous substances (including,
without   limitation,   petroleum,   its   derivatives,   by-products  or  other
hydrocarbons),  and to exposure to hazardous  substances,  the failure to comply
with which could reasonably be expected to have a material adverse effect on the
Company or its properties.  Except as disclosed in the  "Environmental  Matters"
section  of Item 1 of the CWSG  10-K,  the  "Environmental  Matters"  section of
CWSG's 2001 Annual Report and the "Legal  Proceedings"  section of Item 3 of the
CWSG 10-K with  respect  to  matters in Chico and  Marysville,  California,  the
Company does not know of any  liability of the Company  under the  Comprehensive
Environmental  Response,  Compensation  and Liability Act of 1980, as amended by
the Superfund Amendments and Reauthorization Act of 1986 (42 U.S.C. Section 9601
et seq.) with respect to any property now or  heretofore  owned or leased by the
Company.

         21.  Full  Disclosure.  The  financial  statements  referred  to in the
Seventh  Supplement  do not,  nor  does  the  Seventh  Supplement,  the  Company
Information  or any written  statement  (including  without  limitation the 2001
Company  Report and the 2001 CWSG  Report)  furnished  by the  Company to you in
connection with the  negotiation of the sale of the Series I Notes,  contain any
untrue  statement of a material  fact or, taken  together,  omit a material fact
necessary to make the  statements  contained  therein or herein not  misleading.
There is no fact which the Company  has not  disclosed  to you in writing  which
materially  affects  adversely nor, so far as the Company can now foresee,  will
materially  affect  adversely the properties,  business,  prospects,  profits or
condition  (financial or otherwise) of the Company or the ability of the Company
to perform its obligations under the Note Agreement,  the Seventh  Supplement or
the Series I Notes.

         22. Private Offering.  Neither the Company, directly or indirectly, nor
any agent on its  behalf  has  offered  or will  offer the Series I Notes or any
similar Security or has solicited or will solicit an offer to acquire the Series
I Notes or any similar  Security from or has otherwise  approached or negotiated
or will  approach or  negotiate  in respect of the Series I Notes or any similar
Security  with any  Person  other than the  Purchaser  and not more than 7 other
institutional  investors,  each of whom was  offered a portion  of the  Series I
Notes  at  private  sale  for  investment.  Neither  the  Company,  directly  or
indirectly,  nor any agent on

                                      E-2-7
<PAGE>

its behalf has offered or will offer the Series I Notes or any similar  Security
or has  solicited  or will solicit an offer to acquire the Series I Notes or any
similar  Security  from any Person so as to cause the  issuance  and sale of the
Series  I Notes  not to be  exempt  from  the  provisions  of  Section  5 of the
Securities Act of 1933, as amended.

                         DESCRIPTION OF CLOSING OPINION
                            OF COUNSEL TO THE COMPANY

         The closing opinion of Bingham  McCutchen LLP, counsel for the Company,
which is called for by Section  5(a)(iii)  of the Seventh  Supplement,  shall be
dated the Closing Date and addressed to the Purchaser,  shall be satisfactory in
scope and form to the Purchaser and shall be to the effect that:

                    1. The Company is a corporation duly  incorporated,  validly
         existing and in corporate good standing under the laws of California.

                    2. The  execution  and  delivery  by the Company of the Note
         Agreement, the Seventh Supplement and the Notes, and the performance by
         the Company of its obligations  under the Note  Agreement,  the Seventh
         Supplement and the Notes, are within the Company's corporate powers and
         have been duly authorized by all requisite corporate action on the part
         of the Company.  The Company has duly  executed and  delivered the Note
         Agreement, the Seventh Supplement and the Notes.

                    3. Each of the Note  Agreement,  the Seventh  Supplement and
         the Notes  constitutes  a valid and binding  agreement  of the Company,
         enforceable  against the Company in accordance with its terms. Based on
         Section 1646.5 of the California  Civil Code, a California  state court
         and a Federal court which applies the law of the State of California to
         the  Note  Agreement,  the  Seventh  Supplement  and  the  Notes  would
         recognize and give effect to the choice of law  provisions set forth in
         the Note Agreement, the Seventh Supplement and the Notes.

                    4. The  execution  and  delivery  by the Company of the Note
         Documents,  and compliance by the Company with the  provisions  thereof
         (i) will  not,  to the best of our  knowledge,  result  in a breach  or
         default  (or give rise to any  right of  termination,  cancellation  or
         acceleration)  under the  Articles of  Incorporation  or By-Laws of the
         Company,  or the Mortgage  Indenture,  the Credit Agreement dated as of
         July  31,   2001,   between   the   Company  and  Bank  of  America  as
         Administrative  Agent,  or any  agreement or other  instrument  that is
         listed as a material  contract in CWSG's Annual Report on Form 10-K for
         the year ended  December 31,  2001.  To the best of our  knowledge,  no
         consent or approval  by, or any  notification  of or filing  with,  any
         court,  public body or authority of the State of California is required
         to be  obtained  or  effected  by the  Company in  connection  with the
         execution,  delivery  and  performance  by  the  Company  of  the  Note
         Documents  or the  issuance  or  sale  of the  Notes,  except  for  the
         authorization  of the  Commission,  which  authorization  has been duly
         obtained and is in full force and effect.

                    5. Based upon the  representations set forth in Section 6 of
         the Seventh Supplement, the accuracy of which we have not independently
         verified or investigated,  the issuance, sale and delivery of the Notes
         under the circumstances  contemplated by the Seventh Supplement do not,
         under  existing law,  require the  registration  of the Notes under the
         Securities Act of 1933, as amended, or the qualification of the Seventh
         Supplement  or an indenture  under the Trust  Indenture Act of 1939, as
         amended.

                                    EXHIBIT 3
                                 (to Supplement)

<PAGE>

                    6. Based upon the  assumption of the accuracy of information
         obtained  by the  Company  from  sources  believed by the Company to be
         reliable (a) that the  following  cities served by the Company were all
         incorporated prior to 1911:

                 Bakersfield       Marysville         South San Francisco
                 Chico             Oroville           Stockton
                 Dixon             Redondo Beach      Visalia
                 Hermosa Beach     Salinas            Willows
                 King City         San Mateo
                 Livermore         Selma

                  (b) that  water  distribution  systems  were  constructed  and
service  furnished to the  inhabitants  of each by various  predecessors  of the
Company prior to 1911; and

                  (c) that there were no public water works owned or  controlled
by the municipality in any of them prior to 1911;

                         in our opinion,

                         (i) the Company  has a  "constitutional"  franchise  in
         each of the above cities and under such "constitutional"  franchise has
         a perpetual  right which was not  repealed by the repeal of Article XI,
         Section 19, of the California Constitution to continue to occupy public
         streets  of each of said  cities  with  pipes and mains and to lay down
         additional  pipes and mains in said streets for the supplying of water,
         subject to reasonable regulation by the respective municipalities;

                        (ii) this right is not limited to streets in which pipes
         or mains were laid prior to 1911 but extends at least to all streets in
         the said  municipalities  as they  existed at the date of repeal of the
         constitutional provision in 1911; and

                       (iii)  the  right  probably  also  extends  to  territory
         annexed  into each  respective  city after such repeal,  although  this
         latter  question  is not  entirely  free from doubt in the absence of a
         final decision of the courts thereon.

                    7.   Dominguez   Services   Corporation   (along   with  its
         subsidiaries,  "Dominguez")  was merged into the Company  effective May
         25, 2000 and  Dominguez  Water Company was also merged into the Company
         effective  October 12,  2000.  In the  Dominguez  mergers,  the Company
         acquired the operations of Dominguez,  which to our knowledge  included

                DESCRIPTION OF SPECIAL COUNSEL'S CLOSING OPINION

         The  closing  opinion of Chapman  and  Cutler,  special  counsel to the
Purchaser,  called for by Section 5(a)(iii) of the Seventh Supplement,  shall be
dated the Closing Date and addressed to the Purchaser,  shall be satisfactory in
form and substance to the Purchaser and shall be to the effect that:

                    1. The Company is a  corporation,  validly  existing  and in
         good  standing  under the laws of the State of  California  and has the
         corporate power and the corporate  authority to execute and deliver the
         Seventh Supplement and to issue the Series I Notes.

                    2. The Note Agreement and the Seventh  Supplement  have been
         duly  authorized by all necessary  corporate  action on the part of the
         Company,  have been duly  executed  and  delivered  by the  Company and
         constitute  the  legal,  valid  and  binding  contract  of the  Company
         enforceable  in  accordance  with its  terms,  subject  to  bankruptcy,
         insolvency, fraudulent conveyance and similar laws affecting creditors'
         rights  generally,  and general  principles  of equity  (regardless  of
         whether  the   application  of  such  principles  is  considered  in  a
         proceeding in equity or at law).

                    3. The  Series I Notes  have  been  duly  authorized  by all
         necessary  corporate action on the part of the Company,  have been duly
         executed and delivered by the Company and constitute  the legal,  valid
         and binding  obligations of the Company  enforceable in accordance with
         its terms, subject to bankruptcy, insolvency, fraudulent conveyance and
         similar  laws  affecting  creditors'  rights  generally,   and  general
         principles of equity  (regardless  of whether the  application  of such
         principles is considered in a proceeding in equity or at law).

                    4. The  issuance,  sale and  delivery  of the Series I Notes
         under the  circumstances  contemplated  by the Seventh  Supplement does
         not, under existing law, require the registration of the Series I Notes
         under the Securities Act of 1933, as amended,  or the  qualification of
         an indenture under the Trust Indenture Act of 1939, as amended.

         The  opinion of Chapman and Cutler may rely upon the opinion of Bingham
McCutchen LLP as to matters of California law. The opinion of Chapman and Cutler
shall also state that the opinion of Bingham  McCutchen LLP is  satisfactory  in
scope and form to Chapman and Cutler and that, in their  opinion,  the Purchaser
is justified in relying thereon.

         In rendering  the opinion set forth in  paragraph 1 above,  Chapman and
Cutler may rely,  as to matters  referred  to in  paragraph  1,  solely  upon an
examination of the Articles of Incorporation  certified by, and a certificate of
good  standing  of the  Company  from,  the  Secretary  of State of the State of
California,  the By-laws of the Company and the general business corporation law
of the State of California.

         With  respect to  matters  of fact upon  which  such  opinion is based,
Chapman and Cutler may rely on appropriate  certificates of public officials and
officers  of the  Company  and  upon  representations  of the  Company  and  the
Purchaser  delivered  in  connection  with the issuance and sale of the Series I
Notes.
