Thirteenth Supplement to Note Agreement

Dated as of
August 31, 2006

To the Purchaser named in
Schedule A hereto

Ladies and Gentlemen:

This Thirteenth Supplement to Note Purchase Agreement (the “Thirteenth Supplement") is between California Water Service Company (the “Company") whose address is 1720 North First Street, San Jose, California 95112 and the institutional investor named on Schedule A attached hereto (the “Purchaser").

Reference is hereby made to that certain Note Agreement dated as of March 1, 1999 (the “Note Agreement") between the Company and the Purchaser. All capitalized terms not otherwise defined herein 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:

1. The Company has authorized the issue and sale of $20,000,000 aggregate principal amount of its 6.02% Series O Senior Notes due August 31, 2031 (the “Series O Notes"). The Series O Notes, together with the Series B Notes initially issued pursuant to the Note Agreement, the Series C Notes issued pursuant to the First Supplement to Note Agreement dated as of October 1, 2000, the Series D Notes issued pursuant to the Second Supplement to Note Agreement dated as of September 1, 2001, the Series E Notes issued pursuant to the Third Supplement to Note Agreement dated as of May 1, 2002, the Series F Notes issued pursuant to the Fourth Supplement to Note Agreement dated as of August 15, 2002, the Series G Notes issued pursuant to the Fifth Supplement to Note Agreement dated as of November 1, 2002, the Series H Notes issued pursuant to the Sixth Supplement to Note Agreement dated as of December 1, 2002, the Series I Notes issued pursuant to the Seventh Supplement to Note Agreement dated as of May 1, 2003, the Series J Notes issued pursuant to the Amended and Restated Eighth Supplement to Note Agreement dated as of May 1, 2003, the Series K Notes issued pursuant to the Ninth Supplement to Note Agreement dated as of February 15, 2003, the Series L Notes issued pursuant to the Tenth Supplement to Note Agreement dated as of February 15, 2003, the Series M Notes issued pursuant to the Eleventh Supplement to Note Agreement dated as of November 3, 2003, the Series N Notes issued pursuant o the Twelfth Supplement to Note Agreement dated as of October 24, 2003 and each Series of Additional Notes which may from time to time be issued pursuant to the provisions of Section 1.4 of the

The Series O Notes 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 hereinafter set forth, the Company agrees to issue and sell to the Purchaser, and the Purchaser agrees to purchase from the Company, Series O Notes in the principal amount set forth opposite the Purchaser’s name on Schedule A hereto at a price of 100% of the principal amount thereof on the closing date hereafter mentioned.

3. Delivery of the $20,000,000 in aggregate principal amount of the Series O Notes will be made at the offices of Chapman and Cutler LLP, 111 West Monroe Street, Chicago, Illinois 60603-4080 against payment therefor in Federal Reserve or other funds current and immediately available at the principal office of Bank of America, ABA No. 121000358, Account No. 14872 00230, Account Name: California Water Service Company General Account, in the amount of the purchase price at 11:00 A.M., San Francisco, California time, on August 31, 2006 or such later date (not later than September 8, 2006) as shall mutually be agreed upon by the Company and the Purchaser of the Series O Notes (the “Closing Date").

4. Prepayment of Notes.

(a) Required Prepayments. No prepayments are required to be made with respect to the Series O Notes prior to the expressed maturity date thereof other than prepayments made in connection with an acceleration of the Series O 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 Thirteenth 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 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 Thirteenth 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 O 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 O 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 O 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 O 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 O 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 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 O 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 O 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 O 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 O Notes on the Closing Date shall be subject to the performance by the Company of its agreements hereunder which by the terms hereof are to be performed at or prior to the time of delivery of the Series O Notes and to the following further conditions precedent:

(vii) Purchase Permitted By Applicable Law.

If requested by the Purchaser, such Purchaser shall have received an Officer’s Certificate certifying as to such matters of fact as such Purchaser may reasonably specify to enable such Purchaser to determine whether such purchase is so permitted.

(viii) Payment of Special Counsel Fees. The Company shall have paid, on or before the Closing Date, the fees, charges and disbursements of the Purchaser’s special counsel referred to in (iii) above, to the extent reflected in a statement of such counsel rendered to the Company at least one Business Day prior to the Closing Date.

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 O Notes. The issuance and sale of the Series O Notes and the execution and delivery of the Thirteenth 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 June 30, 2006.

5. Financial Statements and Reports. The Company has furnished the Purchaser with a copy of its audited financial reports for 2003, 2004 and 2005 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 2005, 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 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

Exhibit 2
(to Supplement)

adversely affect the Company or its business, property, assets, operations or condition, financial or other. As of December 31, 2005, 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, 2005, 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 2005 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

E-2-2

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 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 previous advice of outside regulatory 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 such outside regulatory 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

E-2-3

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. The Company’s franchises from the Cities of Palos Verdes Estates, Menlo Park, Woodside and Rancho Palos Verdes terminated in 1977, 1993, 1994 and 2003, respectively. While none of the Cities and the Company 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, as to which the franchise expired without renewal in 1994. Dominguez continued to provide water services to Compton subsequent to the expiration of the franchise, 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. However, as of May 2003, the County of Los Angeles cancelled its Dominguez franchise and incorporated the franchise territory into the Company’s Los Angeles County franchise.

The physical assets of the Company are in sound operating condition, there are no material arrears in the maintenance of any such physical assets which could reasonably be expected to have a material adverse effect on the Company and the Company believes that its sources of water are adequate to meet its requirements for the foreseeable future.

11. Pending Litigation, Proceedings. (a) Other than as disclosed in the Company Reports, 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 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 Thirteenth Supplement or the Series O 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.

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 O 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.

(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 Thirteenth Supplement and compliance by the Company with the provisions thereof and the Series O 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 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 Thirteenth Supplement or the Series O Notes.

22. Private Offering. Neither the Company, directly or indirectly, nor to its knowledge any agent on its behalf has offered or will offer the Series O Notes or any similar Security or has solicited or will solicit an offer to acquire the Series O Notes or any similar Security from or has otherwise approached or negotiated or will approach or negotiate in respect of the Series O Notes or any similar Security with any Person other than the Purchaser and not more than ten (10) other institutional investors, each of whom was offered a portion of the Series O Notes at private sale for investment. Neither the Company, directly or indirectly, nor any agent on its behalf has offered or will offer the Series O Notes or any similar Security or has solicited or will solicit an offer to acquire the Series O Notes or any similar Security from any Person so as to cause the issuance and sale of the Series O Notes not to be exempt from the provisions of Section 5 of the Securities Act of 1933, as amended.
