of DSC issued and outstanding immediately prior to the Effective Time of the
Merger shall, without any further action on the part of DSC or the holder of
such shares, be converted pursuant to the terms of the Agreement of Merger as
set forth in Section 2.3. From and after the Effective Time of the Merger, each
certificate that, prior to the Effective Time of the Merger, represented shares
of DSC shall evidence ownership of shares of CWSG on the basis set forth above.

pursuant to the Agreement of Merger, each outstanding share of DSC Stock
excluding, if any, DSC Perfected Dissenting Shares or shares of DSC Stock held

part of DSC or the holders of any such shares, be converted into 1.18 shares
of CWSG Stock (the "Conversion Ratio").

(b) DSC Perfected Dissenting Shares shall not be converted into shares
of CWSG Stock but shall, after the Effective Time of the Merger, be entitled
only to such rights as are granted them by Chapter 13 of the CGCL. Each
dissenting shareholder who is entitled to payment for his shares of DSC Stock
shall receive such payment in an amount as determined pursuant to Chapter 13 of
the CGCL.

(d) If, prior to the Effective Time of the Merger, CWSG shall declare
a stock dividend or distribution upon or subdivide, split up, reclassify or
combine the CWSG Stock, or make a distribution on the CWSG Stock in any security
convertible into CWSG Stock, as of a record date prior to the Effective Time of
the Merger, appropriate adjustment or adjustments (rounded to four digits to the
right of the decimal point) will be made to the Conversion Ratio.

(e) If any DSC Stock Options which are exercisable at the date of this
Agreement, or become exercisable prior to the Closing, are exercised prior to
the Closing, the shares of DSC Stock issued upon such exercise shall be
converted to the right to receive shares of CWSG Stock at the Closing.

certificates representing the shares of CWSG Stock issuable pursuant to
Section 2.3 in exchange for shares of DSC Stock outstanding immediately prior to
the Effective Time of the Merger, and funds in an amount not less than the
amount of cash payable in lieu of fractional shares of CWSG Stock which would
otherwise be payable in connection with Section 2.3 hereof but for the operation
of Section 2.5 of this Agreement (collectively, the "Exchange Fund").

(b) CWSG shall direct the Exchange Agent to mail, promptly after the
Effective Time of the Merger, to each holder of record of a certificate or
certificates which immediately

prior to the Effective Time of the Merger represented outstanding shares of
DSC Stock (the "Certificates") whose shares were converted into the right to
receive shares of CWSG Stock pursuant to Section 2.3 hereof, (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon delivery of the
Certificates to the Exchange Agent and shall be in such form and have such
other provisions as CWSG and DSC may reasonably specify), and (ii)
instructions for use in effecting the surrender of the Certificates in
exchange for certificates representing shares of CWSG Stock. Upon surrender
of a Certificate for cancellation to the Exchange Agent or to such other
agent or agents as may be appointed by CWSG, together with such letter of
transmittal, duly executed, the holder of such Certificate shall be entitled
to receive in exchange therefor that amount of cash and a certificate
representing that number of whole shares of CWSG Stock which such holder has
the right to receive pursuant to the provisions of Sections 2.3 and 2.5
hereof, and the Certificate so surrendered shall forthwith be canceled. In
the event a certificate is surrendered representing DSC Stock, the transfer
of ownership which is not registered in the transfer records of DSC, a
certificate representing the proper number of shares of CWSG Stock may be
issued to a transferee if the Certificate representing such DSC Stock is
presented to the Exchange Agent, accompanied by all documents required to
evidence and effect such transfer and by evidence that any applicable stock
transfer taxes have been paid. Until surrendered as contemplated by this
Section 2.6, each Certificate shall be deemed at any time after the Effective
Time of the Merger to represent only the right to receive upon such surrender
the certificate representing shares of CWSG Stock and cash in lieu of any
fractional shares of stock as contemplated by this Section 2.6.
Notwithstanding anything to the contrary set forth herein, if any holder of
shares of DSC should be unable to surrender the Certificates for such shares,
because they have been lost or destroyed, such holder may deliver in lieu
thereof such affidavit or bond in form and substance and with surety
reasonably satisfactory to CWSG and shall be entitled to receive the
certificate representing the proper number of shares of CWSG Stock and cash
in lieu of fractional shares in accordance with Sections 2.3 and 2.5 hereof.

(c) No dividends or other distributions declared or made after the
Effective Time of the Merger with respect to CWSG Stock with a record date after
the Effective Time of the Merger shall be paid to the holder of any
unsurrendered Certificate with respect to the shares of CWSG Stock represented
thereby and no cash payment in lieu of fractional shares shall be paid to any
such holder pursuant to Section 2.5 until the holder of record of such
Certificate shall surrender such Certificate. Subject to the effect of
applicable laws, following surrender of any such Certificate, there shall be
paid to the record holder of the certificates representing whole shares of CWSG
Common Stock issued in exchange thereof, without interest, (i) at the time of
such surrender, the amount of any cash payable in lieu of a fractional share of
CWSG Stock to which such holder is entitled pursuant to Section 2.5 and the
amount of dividends or other distributions with a record date after the
Effective Time of the Merger theretofore paid with respect to such whole shares
of CWSG Stock, and (ii) at the appropriate payment date, the amount of dividends
or other distributions with a record date after the Effective Time of the Merger
but prior to surrender and a payment date subsequent to surrender payable with
respect to such whole shares of CWSG Stock.

(d) All shares of CWSG Stock issued upon the surrender for exchange of
DSC Stock in accordance with the terms hereof (including any cash paid pursuant
to Section 2.5) shall be deemed to have been issued in full satisfaction of all
rights pertaining to such shares of DSC Stock, and there shall be no further
registration of transfers on the stock transfer books of the Surviving
Corporation of the shares of DSC Stock which were outstanding immediately prior
to the Effective Time of the Merger. If, after the Effective Time of the
Merger, Certificates are presented to CWSG for any reason, they shall be
canceled and exchanged as provided in this Agreement.

(e) Any portion of the Exchange Fund which remains undistributed to
the shareholders of DSC following the passage of six months after the Effective
Time of the Merger shall be delivered to CWSG, upon demand, and any shareholders
of DSC who have not theretofore complied with this Section 2.6 shall thereafter
look only to CWSG for payment of their claim for CWSG Stock, any cash in lieu of
fractional shares of CWSG Stock and any dividends or distributions with respect
to CWSG Stock.

(f) Neither CWSG, Water Company nor DSC shall be liable to any holder
of shares of DSC Stock for such shares (or dividends or distributions with
respect thereto) or cash from the Exchange Fund delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law.

(g) The Exchange Agent shall not be entitled to vote or exercise any
rights of ownership with respect to the shares of CWSG Stock held by it from
time to time hereunder, except that it shall receive and hold all dividends or
other distributions paid or distributed with respect to such shares of CWSG
Stock for the account of the Persons entitled thereto.

consolidated basis. No administrative actions have been taken or orders issued
in connection with such DSC Filings. As of their respective dates, each of such
DSC Filings (y) complied in all material respects with all laws and regulations
enforced or promulgated by the Governmental Entity with which it was filed (or

4.18 LICENSES AND PERMITS. DSC and the DSC Subsidiaries have all material
licenses and permits that are necessary for the conduct of its business, and
such licenses are in full force and effect, except for any failure to be in full
force and effect that would not, individually or in the aggregate, have a
Material Adverse Effect on DSC. To DSC's knowledge, the respective properties,
assets, operations and businesses of DSC and each of the DSC Subsidiaries are
and

have been maintained and conducted, in all material respects, in compliance
with all applicable licenses and permits. The respective properties and
operations of DSC and each of the DSC Subsidiaries are and have been maintained

the ordinary course of business; or (c) disclosed in a list furnished by DSC to
CWSG (the "DSC UNDISCLOSED LIABILITIES LIST") or on any other DSC List. To
DSC's knowledge, there exists no basis for the assertion against it of any
liability, obligation or claim (including, without limitation, that of any
regulatory authority) that is likely to result in or cause a Material Adverse
Effect on DSC that is not fairly reflected in the Financial Statements of DSC or
otherwise disclosed in this Agreement.

4.20 EMPLOYEE BENEFIT PLANS.

(a) DSC has previously made available to CWSG copies of each "employee
benefit plan," as defined in Section 3(3) of ERISA, which is subject to any
provision of ERISA and covers any employee, whether active or retired, of DSC,
together with all amendments thereto, all related summary plan descriptions (to
the extent one is required by law), the determination letter from the IRS, and
the annual reports for the most recent three years (Form 5500 including, if
applicable, Schedule B thereto) prepared in connection with any such plan. Such
plans are hereinafter referred to collectively as the "Employee Plans." DSC does
not participate in an employee benefit pension plan that is a "multiemployer
plan" within the meaning of Section 3(37) of ERISA that would subject DSC to a
material amount of liability with respect to any such plan. Each Employee Plan
which is intended to be qualified in form and operation under Section 401(a) of
the Code is so qualified and the associated trust for each such Employee Plan is
exempt from tax under Section 501(a) of the Code. No event has occurred that
will subject such Employee Plans to a material amount of tax under Section 511
of the Code. All amendments required to bring each Employee Plan into
conformity with all of the applicable provisions of ERISA, the Code and all
other applicable laws have been made. Except as disclosed in a list furnished
by DSC to CWSG (the "DSC EMPLOYEE PLAN LIST"), all Employee Plans were in
effect for substantially all of 1997, and there has been no material amendment
thereof (other than amendments required to comply with applicable law) or
increase in the cost thereof or benefits thereunder on or after January 1, 1998.

(b) DSC has previously made available to CWSG copies or descriptions
of each plan or Agreement maintained or otherwise contributed to by DSC which is
not an Employee Plan and which (exclusive of base salary and base wages)
provides for any form of current or deferred compensation, bonus, stock option,
profit sharing, benefit, retirement, incentive, group health or insurance,
welfare or similar plan or arrangement for the benefit of any employee or class
of employees, whether active or retired, of DSC (such plans and arrangements
being collectively referred to herein as "Benefit Arrangements"). Except as
disclosed in the DSC Employee Plan List hereto, all Benefit Arrangements which
are in effect were in effect for

substantially all of 1997. There has been no material amendment thereof or
increase in the cost thereof or benefits payable thereunder since January 1,
1998. Except as set forth in the DSC Employee Plan List, there has been no
material increase in the compensation of or benefits payable to any senior
executive employee of DSC since December 31, 1997, nor any employment,
severance or similar contract entered into with any such employee, nor any
amendment to any such contract, since December 31, 1997. There is no
contract, agreement or benefit agreement covering any employee of DSC which
individually or collectively could give rise to the payment of any amount
which would constitute an "excess parachute payment," as such term is defined
in Section 280G of the Code.

(c) With respect to all Employee Plans and Benefit Agreements, DSC is
in material compliance (other than noncompliance the cost or liability for which
is not material) with the requirements prescribed by any and all statutes,
governmental or court orders, or governmental rules or regulations currently in
effect, including but not limited to ERISA and the Code, applicable to such
plans or arrangements. All material government reports and filings required by
law have been properly and timely filed and all information required to be
distributed to participants or beneficiaries has been distributed with respect
to each Employee Plan. DSC has performed all of its obligations under all such
Employee Plans and Benefit Agreements in all material aspects. There is no
pending or, to the knowledge of DSC, threatened legal action, proceeding or
investigation against or involving any Employee Plan or Benefit Agreement which
could result in a material amount of liability to such Employee Plan. To the
knowledge of DSC, no condition exists that could constitute grounds for the
termination of any Employee Plan under Section 4042 of ERISA; no "prohibited
transaction," as defined in Section 406 of ERISA and Section 4975 of the Code,
has occurred with respect to any Employee Plan, or any other employee benefit
plan maintained by DSC which is covered by Title I of ERISA, which could subject
any person (other than a person for whom DSC is not directly or indirectly
responsible) to a material amount of liability under Title I of ERISA or to the
imposition of a material amount of tax under Section 4975 of the Code which
could have a Material Adverse Effect on DSC; nor has any Employee Plan subject
to Part III of Subtitle B of Title I of ERISA or Section 412 of the Code, or
both, incurred any "accumulated funding deficiency," as defined in Section 412
of the Code, whether or not waived, nor has DSC failed to make any contribution
or pay any amount due and owing as required by the terms of any Employee Plan or
Benefit Arrangement. No "reportable event" as defined in ERISA has occurred
with respect to any of the Employee Plans. To the knowledge of DSC, DSC has not
incurred nor expects to incur, directly or indirectly, a material amount of
liability under Title IV of ERISA arising in connection with the termination of,
or a complete or partial withdrawal from, any plan covered or previously covered
by Title IV of ERISA which could constitute a liability of CWSG or of any of its
affiliates (including DSC) at or after the Effective Time of the Merger.

(d) Except for DSC Scheduled Contracts set forth in the DSC Contract
List or as set forth in the DSC Employee Plan List, as the case may be, each
Employee Plan or Benefit Arrangement and each personal services contract, fringe
benefit, consulting contract or similar arrangement with or for the benefit of
any officer, director, employee or other person can be terminated by DSC within
a period of 30 days following the Effective Time of the Merger,

without payment of any amount as a penalty, bonus, premium, severance pay or
other compensation for such termination.

(e) All group health plans of DSC have been operated in compliance
with the group health plan continuation coverage requirements of Section 4980B
of the Code in all material respects.

4.21 CORPORATE RECORDS. The minute books of DSC and each of the DSC
Subsidiaries since the later of January 1, 1994 or the date which any DSC
Subsidiary became a DSC Subsidiary accurately reflect all material actions taken
from year end 1993 to this date by the respective shareholders, board of
directors and committees of DSC and each of the DSC Subsidiaries.

4.22 ACCOUNTING RECORDS. DSC and each of the DSC Subsidiaries maintains
accounting records which fairly and validly reflect, in all material respects,
its transactions, and accounting controls exist sufficient to provide reasonable
assurances that such transactions are, in all material respects, (i) executed in
accordance with its management's general or specific authorization, and (ii)
recorded as necessary to permit the preparation of financial statements in
conformity with generally accepted accounting principles. Such records, to the
extent they contain important information pertaining to DSC and each of the DSC
Subsidiaries which is not easily and readily available elsewhere, have been
duplicated, and such duplicates are stored safely and securely.

4.23 OFFICES. DSC has furnished to CWSG a list (the "DSC OFFICES LIST")
setting forth the headquarters of DSC (identified as such) and each of the
offices maintained and operated by DSC and the location thereof. Except as set
forth on the DSC Offices List, DSC does not maintain any other office or conduct
business at any other location with the exception of offices or locations
utilized as payment facilities.

4.24 INVESTMENT SECURITIES. DSC has furnished to CWSG a list (the "DSC
INVESTMENT SECURITIES LIST") (i) setting forth a description of each Investment

thereof; (ii) the outstanding balance or number of shares; (iii) the maturity,
if applicable; (iv) the title of issue; and (v) the classification under SFAS
No. 115.

4.25 POWER OF ATTORNEY. DSC has not granted any Person a power of attorney
or similar authorization that is presently in effect or outstanding.

4.26 FACTS AFFECTING REGULATORY APPROVALS. To the knowledge of DSC, there
is no fact, event or condition applicable to DSC or any of the DSC Subsidiaries
which will, or reasonably could be expected to, adversely affect the likelihood
of securing the requisite approvals or consents of any Governmental Entity to
the Merger and the transactions contemplated by this Agreement. DSC will file
rate cases with the Commission between the effective date of this Agreement and
the Effective Time of the Merger.

4.27 ACCOUNTING AND TAX MATTERS. To the best knowledge of DSC, DSC has
not, through the date hereof, taken or agreed to take any action that would
prevent CWSG from accounting for the business combination to be effected by the
Merger as a pooling-of-interests or would prevent the Merger from qualifying as
a tax-free reorganization under the Code.

4.28 INDEMNIFICATION. Other than pursuant to the provisions of its
Articles of Incorporation or Bylaws and related indemnification agreements
adopted in order to enact those provisions, DSC is not a party to any
indemnification agreement with any of its present officers, directors,
employees, agents or other persons who serve or served in any other capacity
with any other enterprise at the request of DSC (a "Covered Person"), and to
the best knowledge of DSC, there are no claims for which any Covered Person
would be entitled to indemnification by DSC if such provisions were deemed in
effect, except as set forth in a list furnished by DSC to CWSG (the "DSC
INDEMNIFICATION LIST").

involving forwards, futures, options on futures, swaps or other derivative

(the "DSC YEAR 2000 EXCEPTIONS LIST"), DSC has been and is in material
compliance with the Year 2000 Plan as in effect on the date hereof.

to state any material fact which is necessary under the circumstances under
which they were made to prevent the statements contained herein or therein or in
such schedules from being misleading.

4.33 STANDARD. No representation or warranty of DSC contained in Article
IV shall be deemed untrue or incorrect, and DSC shall not be deemed to have

to any materiality standards contained in any representation or warranty,
individually or taken together with all other facts, circumstances or events
constituting

such breaches, has had or would reasonably be expected to have a
Material Adverse Effect on DSC.

subject to the continuing fiduciary duties of the Board of Directors of DSC to
the shareholders of DSC. In addition, if the Board of Directors of DSC receives
a bona fide proposal for a Competing Transaction which it has determined to be a
Superior Proposal, the Board of Directors may withdraw or modify its approval or
recommendation of this Agreement or the Merger and may terminate this Agreement,
in each case at any time after the fifth (5th) business day following CWSG's

more favorable to DSC's shareholders than the terms of the Merger;

furnished by DSC to CWSG and (iii) developer funded projects in accordance with
the Commission's Tariff Rule 15;

or otherwise dispose of any assets of DSC or the DSC Subsidiaries or release or

which CWSG believes renders any representation or warranty made by DSC

will be prepared in accordance with generally accepted accounting principles or
applicable Commission regulations consistently applied during the periods
involved.

amendments and supplements thereto before the filing thereof. DSC covenants and
agrees that, with respect to the information furnished by DSC or the DSC
Subsidiaries, the Proxy Statement and Prospectus will (i) comply in all
material respects with the provisions of applicable law, and will not contain

6.10 AFFILIATES AND FIVE PERCENT SHAREHOLDER AGREEMENTS. Concurrently with
the execution of this Agreement, (a) DSC shall deliver to CWSG a letter
identifying all persons who are then "affiliates" of DSC for purposes of Rule

such letter of the resale restrictions imposed by applicable securities laws and

who becomes an affiliate of DSC after DSC's delivery of the letter referred to
above, and within 30 days of that person becoming an affiliate of DSC or on or
prior to the date of the DSC Shareholders' Meeting to approve this Agreement,
whichever is earliest, a written agreement substantially in the form attached as
EXHIBIT B hereto as soon as practicable after obtaining such status. At least
10 Business Days prior to the issuance of the opinion to be provided for in
Section 9.6, DSC shall use its commercially reasonable efforts to cause each
person or group of persons who holds more than five percent (5%) of the DSC
Stock (regardless of whether such person is an "affiliate" under Rule 145) to
deliver to Nossaman, Guthner, ▇▇▇▇ & ▇▇▇▇▇▇▇, LLP, a letter stating that such
shareholder(s) has no present plan or intention to dispose of CWSG Stock that
the shareholder(s) will receive in the Merger, and committing that such
shareholder(s) will not dispose of such CWSG Stock in a manner as to cause a
violation of the "continuity of shareholder interest" requirements of Treasury
Regulation 1.368-1.

6.11 COORDINATION OF DIVIDENDS. DSC shall coordinate with CWSG the
declaration of any dividends that may be allowed pursuant to Section 6.1 (b)
hereof, and the record date and the payment dates relating thereto, it being the
intention of the parties that holders of DSC Stock shall not receive two
dividends, or fail to receive one dividend, for any applicable dividend period
with respect to their shares of DSC Stock and any shares of CWSG Stock any such
holder will receive in exchange therefor in the Merger.

6.12 D&O COVERAGE. Prior to the Effective Time of the Merger, DSC shall
obtain a policy of insurance insuring directors and officers of DSC and the DSC
Subsidiaries, and those persons who become directors and officers of DSC or the
DSC Subsidiaries between the date of this Agreement and the Effective Time of
the Merger. This insurance shall be no less protective in terms of policy
limits, coverage or limitations than the insurance for officers and directors
maintained by DSC at the date of this Agreement (the "Current D& O Coverage").
The Current D&O Coverage insures those persons covered by it in an aggregate
amount of $22,000,000, consisting of $3,000,000 of primary coverage and
$19,000,000 of excess (umbrella) coverage. The new D&O insurance to be obtained
by DSC hereunder (the "New Policy") shall provide coverage for a period of up to
48 months following the Effective Time of the Merger and shall cover acts and
omissions occurring prior to the Effective Time of the Merger and acts and
omissions relating to this Agreement and the actions contemplated hereby to the
extent such insurance is commercially available. The above notwithstanding, DSC
shall not obtain or pay

for any coverage under the New Policy requiring an annual premium in excess
of 150% of the annual premium that DSC pays for the Current D&O Coverage,
plus any general increases in the cost of D&O insurance between the date of
this Agreement and the periods covered by the New Policy.

8.5 CONFIDENTIALITY AND NON-DISCLOSURE.

(a) Each party has furnished and will furnish information concerning its
business (herein collectively referred to as the "Evaluation Material") to the
other party. Each party agrees to use the Evaluation Material received from the
other only in accordance with the provisions of this Agreement and to take or
refrain from taking certain other actions set forth herein. The term "Evaluation
Material" shall include any and all information, oral or written, concerning the
Merger or any other actual or potential transaction between the parties or
concerning the parties' respective businesses, which heretofore has been or
hereafter is disclosed by CWSG or DSC, or any of their respective partners,
directors, officers, shareholders, employees, agents or advisors (for the
purposes of this Section 8.5 and Section 8.6, collectively called
"representatives"), either directly or indirectly, in writing, orally or by
physical inspection, and whether disclosed prior to or after the date of this
Agreement, together with all analyses, compilations, studies or other data,
documents or records prepared by either party or any of its representatives
which contain or otherwise reflect or are generated from any such information or
documents. Evaluation Material does not include information

that is (i) publicly known (other than as a result of a breach of this
Agreement), (ii) approved for release by written authorization of the party
that provided such information, or (iii) lawfully obtained from third parties
who are not bound by a confidentiality agreement with the party that provided
such information.

(b) CWSG and DSC each agrees that the Evaluation Material will be used
solely for purposes of this Agreement and the transactions contemplated hereby,
and not in connection with the consideration of any other transaction,
including, without limitation, any other transaction or investment directly or
indirectly involving the other party, and that all information contained therein
will be kept confidential by such party. CWSG and DSC may disclose such
Evaluation Material to their representatives who need to have access to such
Evaluation Material in connection with the Merger; provided, that each party
shall advise all of its representatives to whom the Evaluation Material is
disclosed of its obligations under this Agreement and shall take all reasonable
steps to insure that such persons or entities to whom disclosure is made shall
have been advised of the confidentiality thereof and shall have agreed, for the

those set forth in this Agreement. CWSG and DSC each agrees that it shall
protect the confidentiality of and avoid disclosure or use of the Evaluation
Material, except (i) as permitted in writing by an authorized representative of
the other party and (ii) for disclosure to such party's representatives who need
to know such information for purposes of evaluating the possible Merger between
CWSG and DSC. In complying with its obligations herein, each party shall
exercise at least the same degree of care to safeguard the Evaluation Material
received from the other party as it would use if the confidential information
contained therein were its own confidential information.

(c) In the event that either party or its representatives is required in
any proceeding to disclose any Evaluation Material, such party (for the purposes
of this Section 8.5 (c), the "Compelled Party") will give the other party prompt
notice so that the other party may seek an appropriate protective order. If, in
the absence of a protective order, the Compelled Party or its representatives is
compelled to disclose such Evaluation Material, the Compelled Party or its
representatives as the case may be, may disclose such information to the extent
compelled to do so in such proceeding without liability hereunder; provided,
however, that the Compelled Party shall give the other party written notice of
the information to be disclosed as far in advance of the disclosure as is
practicable and shall use its best efforts to obtain assurances that
confidential treatment will be accorded to such information.

8.6 RETURN OF MATERIALS. If this Agreement is terminated or the Merger is
otherwise not consummated, each party shall promptly redeliver all written
Evaluation Material received from the other party, and all documents, memoranda,
notes and other writings whatsoever prepared by such party or any of its
representatives based on the information in any of the Evaluation Material
received from the other party shall be destroyed. It is expressly understood
and agreed by the parties hereto that their respective obligations hereunder
shall survive the return of materials as set forth above and the termination,
expiration or rescission of this Agreement.

(d) The party owing liquidated damages ("Paying Party") shall make
such payment to that party which is owed liquidated damages ("Receiving Party")
in immediately available funds within 30 days following the day on which the
Receiving Party properly notifies the Paying party in writing that one of the
events described in Section 14.2, subdivisions (b) and (c) hereof has occurred.
The Paying Party shall make such payment as compensation and liquidated damages
for the loss suffered by Receiving Party as a result of the failure of the
Merger to be consummated and to avoid the difficulty of determining damages in
that circumstance.

(e) The payment of liquidated damages to CWSG, pursuant to subdivision
(b) or (c) of this Section 14.2, shall be a one time payment regardless of the
number of times an event occurs or the number of events which occur that would
trigger payments.

which sum represents (i) the Receiving Party's direct costs and expenses
(including, but not limited to, fees and expenses of financial or other
consultants, printing costs, accountants, and counsel) incurred in negotiating
and undertaking to carry out the transactions contemplated by this Agreement,
including the Receiving Party's management time devoted to negotiation and
preparation for the transactions contemplated by this Agreement; (ii) the
Receiving Party's indirect costs and expenses incurred in connection with the
transactions contemplated by this Agreement; and (iii) the Receiving Party's
loss as a result of the transactions contemplated by this Agreement not being
consummated. Any payment previously made by the Paying Party pursuant to
Section 14.1(a) or 14.1(b) hereof shall be credited against any amount due under
this Section.

completed by the Drop Dead Date or which transaction any Governmental Entity
advised CWSG in writing would result in the disapproval of the transactions
contemplated in this Agreement, if such transaction is consummated prior to

in Section 14.1 (but not limited to $1,500,000), DSC shall be entitled to all
other rights and remedies available to it at law or in equity, which rights
and remedies shall not be subject to the limitations contained in Section

FORM OF AFFILIATE AGREEMENT

Exhibit B

AFFILIATE LETTER

California Water Service Group
▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇
▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇

Gentlemen:

I have been advised that I might be considered to be an "affiliate" of
▇▇▇▇▇▇▇▇▇ Services Corporation, a California corporation ("DSC"), for purposes
of paragraphs (c) and (d) of Rule 145 promulgated by the Securities and Exchange
Commission (the "SEC") under the Securities Act of 1933, as amended (the "Act"),
and for purposes of generally accepted accounting principles ("GAAP") as such
term relates to pooling-of-interests accounting treatment for certain business
combinations under GAAP and the interpretations of the SEC or its staff,
including, without limitation, Section 201.01 of the SEC's Codification of
Financial Reporting Policies ("Section 201.01") and the SEC's Staff Accounting
Bulletin No. 65.

California Water Service Group ("CWSG"), California Water Service Company
("Water Company") and DSC have entered into an Agreement and Plan of
Reorganization, dated as of November 13, 1998 (the "Merger Agreement").
Pursuant to the terms of the Merger Agreement, upon consummation of the Merger
described therein (the "Merger"), I will be entitled to receive shares of CWSG
common stock, no par value ("CWSG Stock"), in exchange for my shares of common
stock of DSC ("DSC Stock"). This agreement is hereinafter referred to as this
"Letter Agreement."

A. I represent and warrant to, and agree with, CWSG as follows;

1. I have read this Letter Agreement and the Merger Agreement and have
discussed their requirements and other applicable limitations upon my ability to
sell, pledge, transfer or otherwise dispose of shares of CWSG Stock and DSC
Stock, to the extent I felt necessary, with my counsel or counsel for DSC.

2. I have been advised that any issuance of shares of CWSG Stock to me
pursuant to the Merger will be registered with the SEC. I have also been
advised, however, that, because I may be an "affiliate" of DSC at the time the
Merger will be submitted for a vote of the shareholders of DSC and my offer,
sale, transfer or other disposition of shares of CWSG Stock has not been
registered under the Act, I shall not make any offer, sale, pledge, transfer or
other disposition of such shares unless (i) such offer, sale, transfer or other
disposition of such shares is subject to an effective registration statement and
to the availability of a prospectus under the Act, (ii) a sale of such shares is
made in conformity with the provisions of Rule 145(d) under the Act (and I agree
to provide those representations as CWSG may reasonably request in order to
determine such conformity) or (iii) in an opinion of counsel, in form and
substance reasonably satisfactory to CWSG, some other

exemption from registration is available with respect to any such proposed
disposition of such shares. I further agree that I will not cause my shares
to become dissenting shares as defined in Section 1300 of the CGCL.

3. Notwithstanding the foregoing and any other agreements on my part in
connection with CWSG Stock and any other capital stock of CWSG and DSC Stock
and any other capital stock of DSC, I hereby agree that I will not, without
prior written consent of CWSG, pledge, sell or otherwise reduce my risk
relative to any shares of DSC Stock or CWSG Stock (whether received in the
Merger or otherwise) during the period commencing 30 days prior to the
effective date of the Merger and continuing until financial results covering
at least thirty (30) days of combined operations have been published
following the effective date of the Merger within the meaning of Section
201.01; provided, however, that this paragraph shall not prevent me from
selling, transferring or disposing (in each case, with prior written approval
of CWSG) of such number of shares of CWSG Stock or DSC Stock as will not, in
the reasonable judgment of accountants to CWSG, interfere with or prevent the
Merger from being accounted for as a "pooling-of-interests."

4. Stop transfer instructions may be given to the transfer agent of DSC
with respect to the shares of DSC Stock and to the transfer agent of CWSG
with respect to the shares of CWSG Stock in connection with the restrictions
set forth herein, and there will be placed on the certificate representing
shares of CWSG Stock I receive pursuant to the Merger, or any certificates
delivered in substitution therefor, a legend stating in substance:

The shares represented by this certificate were issued in a
transaction to which Rule 145 under the Securities Act of 1933
applies. The shares represented by this certificate may only be
transferred in accordance with the terms of an agreement between the
registered holder hereof and CWSG, a copy of which agreement is on
file at the principal offices of CWSG. A copy of such agreement shall
be provided to the holder hereof without charge upon receipt by CWSG
of a written request.

5. Unless a transfer of my shares of CWSG Stock is a sale made in
conformity with the provisions of Rule 145(d) under the Act, or made pursuant
to any effective registration statement under the Act, CWSG reserves the
right to put an appropriate legend on the certificates issued to my
transferee.

6. I recognize and agree that the foregoing provisions also apply to
(i) my spouse, (ii) any relative of mine or my spouse occupying my home,
(iii) any trust or estate in which I, my spouse or any such relative owns at
least a 10% beneficial interest or of which any of us serves as trustee,
executor or in any similar capacity and (iv) any corporation or other
organization in which I, my spouse or any such relative owns at least a 10%
of any class of equity securities or of the equity interest.

7. I further recognize that in the event I become a director or officer
of CWSG upon consummation of the Merger, any purchase or sale of the capital
stock of CWSG by me may be subject to liability pursuant to Section 16(b) of
the Securities Exchange Act of 1934, as amended.

Affiliate Letter

8. Execution of this letter should not be construed as an admission on
my part that I am an "affiliate" of DSC as described in the first paragraph
of this Letter Agreement or as a waiver of any rights I may have to object to
any claim that I am such an affiliate on or after that date of this Letter
Agreement.

It is understood and agreed that this Letter Agreement shall terminate
and be of no further force and effect if the Merger Agreement is terminated
in accordance with its terms. It is also understood and agreed that this
Letter Agreement shall terminate and be of no further force and effect and
the stop transfer instructions set forth in Paragraph 4 above shall be lifted
forthwith upon the later of (i) such time as financial results covering at
least thirty (30) days of combined operations following the effective date of
the Merger have been published within the meaning of Section 201.01 and (ii)
delivery by the undersigned to CWSG of a copy of a letter from the staff of
the SEC, an opinion of counsel in form and substance reasonably satisfactory
to CWSG, or representations or other evidence reasonably satisfactory to
CWSG, to the effect that a transfer of my shares of CWSG Stock represented by
such certificate or certificates will not violate the Act or any of the rules
and regulations of the SEC thereunder. In addition, it is understood and
agreed that the legend set forth in Paragraph 4 above shall be removed
forthwith from the certificate or certificates representing my shares of CWSG
Stock if I shall have delivered to CWSG a copy of a letter from the staff of
the SEC, an opinion of counsel in form and substance reasonably satisfactory
to CWSG or other representations or evidence reasonably satisfactory to CWSG
that a transfer of my shares of CWSG Stock represented by such certificate or
certificates will be a sale made in conformity with the provisions of Rule
145(d) under the Act, or made pursuant to an effective registration statement
under the Act, or that such legend is not required for purposes of the
Securities Act or the rules and regulation promulgated thereunder.

This Letter Agreement shall be binding on my heirs, legal representative
and successors.

Very truly yours,
