                                 LOAN AGREEMENT

This  Agreement  dated as of December 23, 2004,  is among Bank of America,  N.A.
(the  "Bank"),  California  Water  Service  Group  ("Borrower  1"),  CWS Utility
Services  ("Borrower  2"),  New Mexico Water  Service  Company  ("Borrower  3"),
Washington Water Service Company ("Borrower 4") and Hawaii Water Service Company
("Borrower  5")  (Borrower 1,  Borrower 2, Borrower 3, Borrower 4 and Borrower 5
are sometimes  referred to collectively  as the "Borrowers" and  individually as
the "Borrower").

1.       FACILITY NO. 1: LINE OF CREDIT AMOUNT AND TERMS

1.1      Line of Credit Amount.

(a)      During the availability period described below, the Bank will provide a
         line of credit to the Borrowers.  The amount of the line of credit (the
         "Facility  No.  1  Commitment")  is  Ten  Million  and  00/100  Dollars
         ($10,000,000.00).

(b)      This is a revolving line of credit. During the availability period, the
         Borrowers may repay principal amounts and reborrow them.

(c)      The Borrowers agree not to permit the principal balance  outstanding to
         exceed the  Facility No. 1  Commitment.  If the  Borrowers  exceed this
         limit,  the Borrowers will  immediately pay the excess to the Bank upon
         the Bank's demand.

1.2      Availability  Period.  The line of credit is available between the date
         of this  Agreement  and April 30,  2007,  or such  earlier  date as the
         availability may terminate as provided in this Agreement (the "Facility
         No. 1 Expiration Date").

1.3      Repayment Terms.

(a)      The Borrowers  will pay interest on December 31, 2004,  and then on the
         same  day of  each  month  thereafter  until  payment  in  full  of any
         principal outstanding under this facility.

(b)      The  Borrowers  will  repay in full any  principal,  interest  or other
         charges  outstanding under this facility no later than the Facility No.
         1 Expiration  Date. Any interest  period for an optional  interest rate
         (as  described  below)  shall  expire no later than the  Facility No. 1
         Expiration Date.

1.4      Interest Rate.

(a)      The  interest  rate is a rate per year equal to the  Bank's  Prime Rate
         minus the Applicable Margin as defined below.

(b)      The Prime Rate is the rate of interest publicly  announced from time to
         time by the Bank as its Prime  Rate.  The Prime Rate is set by the Bank
         based on  various  factors,  including  the  Bank's  costs and  desired
         return, general economic conditions and other factors, and is used as a
         reference point for pricing some loans. The Bank may price loans to its
         customers at, above,  or below the Prime Rate.  Any change in the Prime
         Rate shall take effect at the opening of business on the day  specified
         in the public announcement of a change in the Bank's Prime Rate.

1.5      Optional Interest Rates. Instead of the interest rate based on the rate
         stated in the paragraph  entitled  "Interest Rate" above, the Borrowers
         may elect the optional  interest  rates listed below for this  Facility
         No. 1 during interest  periods agreed to by the Bank and the Borrowers.
         The  optional  interest  rates  shall  be  subject  to  the  terms  and
         conditions  described  later in this  Agreement.  Any principal  amount
         bearing  interest at an optional rate under this  Agreement is referred
         to as a "Portion." The following optional interest rates are available:

(a)      The LIBOR Rate plus the Applicable Margin as defined below.

1.6      Applicable Margin. The Applicable Margin shall be the following amounts
         per annum,  based  upon the Debt to  Capitalization  Ratio (as  defined
         below) as  calculated  on a  consolidated  basis from Borrower 1's most
         recent  financial  statement  received  by the Bank as  required in the
         Covenants section; provided,  however, that until the Bank receives the
         first  financial  statement,  such amounts shall be those indicated for
         pricing level 1 set forth below:

                                       1



                                                        Applicable Margin
                                                (in percentage points per annum)
 Pricing Level            Ratio                   Prime Rate -    LIBOR Rate +
- --------------------------------------------------------------------------------
       1             less than 0.50:1.00             1.000           0.775
       2             equal to or greater than        0.750           0.900
                     0.50:1.00 and
                     less than 0.55:1.00
       3             equal to or greater than        0.625           1.025
                     0.55:1.00 and
                     less than 0.60:1.00
       4             equal to or greater than        0.500           1.150
                     0.60:1.00


"Debt to Capitalization  Ratio" means the ratio of Funded Debt to the sum of Net
Worth plus Funded Debt.  "Funded  Debt" means all  outstanding  liabilities  for
borrowed money and other  interest-bearing  liabilities of Borrower 1, including
current and  long-term  debt.  "Net Worth" means the value of Borrower 1's total
assets  (including  leaseholds and leasehold  improvements  and reserves against
assets)  less its total  liabilities,  including  but not limited to accrued and
deferred income taxes.

The Applicable Margin shall be in effect from the date the most recent financial
statement is received by the Bank until the date the next financial statement is
received;  provided,  however,  that if the Borrowers fail to timely deliver the
next financial  statement,  the  Applicable  Margin from the date such financial
statement  was due until the date such  financial  statement  is received by the
Bank shall be the highest pricing level set forth above.

1.7      Letters of Credit.

(a)      During the availability  period,  at the request of the Borrowers,  the
         Bank will issue  standby  letters of credit with a maximum  maturity of
         three hundred  sixty-five  (365) days but not to extend more than three
         hundred  sixty five (365) days  beyond the  Facility  No. 1  Expiration
         Date. The standby  letters of credit may include a provision  providing
         that the maturity date will be automatically  extended each year for an
         additional year unless the Bank gives written notice to the contrary.

(b)      The  amount  of the  letters  of  credit  outstanding  at any one  time
         (including the drawn and unreimbursed amounts of the letters of credit)
         may not exceed Five Million and 00/100 Dollars ($5,000,000.00).

(c)      In calculating the principal amount  outstanding under the Facility No.
         1 Commitment,  the calculation  shall include the amount of any letters
         of credit outstanding, including amounts drawn on any letters of credit
         and not yet reimbursed.

(d)      The Borrowers agree:

         (i)      Any sum drawn  under a letter of credit  may, at the option of
                  the Bank, be added to the principal amount  outstanding  under
                  this  Agreement.  The amount will bear  interest and be due as
                  described elsewhere in this Agreement.

         (ii)     If there is a default  under this  Agreement,  to  immediately
                  prepay and make the Bank whole for any outstanding  letters of
                  credit.

         (iii)    The  issuance of any letter of credit and any  amendment  to a
                  letter of credit is subject to the Bank's written approval and
                  must be in form and  content  satisfactory  to the Bank and in
                  favor of a beneficiary acceptable to the Bank.

         (iv)     To  sign  the  Bank's  form   Application  and  Agreement  for
                  Commercial  Letter of Credit or Application  and Agreement for
                  Standby Letter of Credit, as applicable.

                                       2



         (v)      To pay any issuance  and/or other fees that the Bank  notifies
                  the  Borrowers  will be charged  for  issuing  and  processing
                  letters of credit for the Borrowers.

         (vi)     To  allow  the Bank to  automatically  charge  any  Borrower's
                  checking  account for applicable  fees,  discounts,  and other
                  charges.

2.       OPTIONAL INTEREST RATES

2.1      Optional  Rates.  Each  optional  interest  rate  is a rate  per  year.
         Interest will be paid on December 31, 2004, and then on the same day of
         each  month   thereafter   until  payment  in  full  of  any  principal
         outstanding  under this  facility.  No Portion  will be  converted to a
         different interest rate during the applicable interest period. Upon the
         occurrence  of an event of default under this  Agreement,  the Bank may
         terminate  the  availability  of optional  interest  rates for interest
         periods  commencing  after  the  default  occurs.  At the  end of  each
         interest  period,  the interest  rate will revert to the rate stated in
         the paragraph(s)  entitled "Interest Rate" above,  unless the Borrowers
         have designated another optional interest rate for the Portion.

2.2      LIBOR  Rate.  The  election  of LIBOR  Rates  shall be  subject  to the
         following terms and requirements:

(a)      The interest  period during which the LIBOR Rate will be in effect will
         be one or two weeks, one month, two months,  three months, four months,
         five months, six months,  seven months,  eight months, nine months, ten
         months,  eleven months or twelve months.  The first day of the interest
         period  must be a day other  than a  Saturday  or a Sunday on which the
         Bank is open for  business  in New  York  and  London  and  dealing  in
         offshore  dollars (a "LIBOR Banking Day"). The last day of the interest
         period and the actual number of days during the interest period will be
         determined  by the Bank using the  practices  of the London  inter-bank
         market.

(b)      Each LIBOR Rate Portion will be for an amount not less than One Hundred
         Thousand and 00/100 Dollars ($100,000.00).

(c)      The "LIBOR Rate" means the interest  rate  determined  by the following
         formula,  rounded  upward to the  nearest  1/100 of one  percent.  (All
         amounts in the  calculation  will be  determined  by the Bank as of the
         first day of the interest period.)

                           LIBOR Rate =     London Inter-Bank Offered Rate
                                            ------------------------------
                                             (1.00 - Reserve Percentage)

         Where,

         (i)      "London  Inter-Bank  Offered Rate" means the average per annum
                  interest rate at which U.S.  dollar  deposits would be offered
                  for the  applicable  interest  period  by  major  banks in the
                  London  inter-bank  market, as shown on the Telerate Page 3750
                  (or any successor  page) at  approximately  11:00 a.m.  London
                  time two (2) London  Banking Days before the  commencement  of
                  the  interest  period.  If such  rate  does not  appear on the
                  Telerate Page 3750 (or any successor  page), the rate for that
                  interest period will be determined by such alternate method as
                  reasonably  selected by the Bank. A "London  Banking Day" is a
                  day on which  the  Bank's  London  Banking  Center is open for
                  business and dealing in offshore dollars.

         (ii)     "Reserve  Percentage"  means the total of the maximum  reserve
                  percentages  for  determining the reserves to be maintained by
                  member banks of the Federal  Reserve  System for  Eurocurrency
                  Liabilities, as defined in Federal Reserve Board Regulation D,
                  rounded  upward  to the  nearest  1/100  of one  percent.  The
                  percentage  will be expressed as a decimal,  and will include,
                  but not be  limited  to,  marginal,  emergency,  supplemental,
                  special, and other reserve percentages.

(d)      The Borrowers shall  irrevocably  request a LIBOR Rate Portion no later
         than 12:00 noon Pacific time on the LIBOR Banking Day preceding the day
         on which the London  Inter-Bank  Offered Rate will be set, as specified
         above.  For example,  if there are no  intervening  holidays or weekend
         days in any of the  relevant  locations,  the  request  must be made at
         least three days before the LIBOR Rate takes effect.

(e)      The Bank will have no obligation to accept an election for a LIBOR Rate
         Portion if any of the  following  described  events has occurred and is
         continuing:

                                       3



         (i)      Dollar deposits in the principal amount, and for periods equal
                  to the  interest  period,  of a  LIBOR  Rate  Portion  are not
                  available in the London inter-bank market; or

         (ii)     The LIBOR Rate does not accurately reflect the cost of a LIBOR
                  Rate Portion.

(f)      Each prepayment of a LIBOR Rate Portion,  whether voluntary,  by reason
         of  acceleration  or otherwise,  will be  accompanied  by the amount of
         accrued  interest  on  the  amount  prepaid  and a  prepayment  fee  as
         described  below.  A  "prepayment"  is a payment of an amount on a date
         earlier than the scheduled  payment date for such amount as required by
         this Agreement.

(g)      The prepayment  fee shall be in an amount  sufficient to compensate the
         Bank for any loss,  cost or expense  incurred  by it as a result of the
         prepayment,  including any loss of anticipated  profits and any loss or
         expense  arising from the liquidation or reemployment of funds obtained
         by it to maintain  such Portion or from fees  payable to terminate  the
         deposits from which such funds were obtained.  The Borrowers shall also
         pay any customary administrative fees charged by the Bank in connection
         with the foregoing.  For purposes of this paragraph,  the Bank shall be
         deemed to have  funded  each  Portion  by a  matching  deposit or other
         borrowing  in the  applicable  interbank  market,  whether  or not such
         Portion was in fact so funded.

3.       FEES AND EXPENSES

3.1      Fees.

(a)      Unused  Commitment  Fee.  The  Borrowers  agree  to  pay a fee  on  any
         difference  between the  Facility  No. 1  Commitment  and the amount of
         credit they actually use, determined by the average of the daily amount
         of credit  outstanding  during the  specified  period.  The fee will be
         calculated at the following percentage points per annum, based upon the
         Debt to Capitalization  Ratio (as defined in Paragraph 1.6 above).  The
         calculation of credit  outstanding shall not include the undrawn amount
         of  letters  of  credit.  The  Debt  to  Capitalization  Ratio  will be
         calculated in the manner  described in Paragraph 1.6 of this Agreement;
         provided,  however,  that until the Bank  receives the first  financial
         statement,  the  fee  will  be  calculated  at  the  percentage  points
         indicated for fee level 1 set forth below:

                                                     Applicable Fee
   Fee Level             Ratio               (in percentage points per annum)
- --------------------------------------------------------------------------------
       1           less than 0.55:1.00                 .125
       2           equal to or greater than            .250
                   0.55:1.00 and
                   less than 0.60:1.00
       3           equal to or greater than            .375
                   0.60:1.00


         This  fee is due on  January  1,  2005,  and on the  same  day of  each
         following quarter until the expiration of the availability period.

         The  Applicable  Fee shall be in effect  from the date the most  recent
         financial  statement  is  received  by the Bank until the date the next
         financial  statement  is  received;  provided,  however,  that  if  the
         Borrowers  fail to timely  deliver the next  financial  statement,  the
         Applicable Fee from the date such financial statement was due until the
         date such  financial  statement  is  received  by the Bank shall be the
         highest fee level set forth above.




(b)      Late Fee. To the extent  permitted by law, the Borrowers agree to pay a
         late fee in an amount not to exceed  four  percent  (4%) of any payment
         that is more than fifteen (15) days late. The imposition and payment of
         a late fee shall not  constitute  a waiver of the  Bank's  rights  with
         respect to the default.

                                       4



3.2      Expenses.  The  Borrowers  agree  to  immediately  repay  the  Bank for
         expenses that include,  but are not limited to,  filing,  recording and
         search fees, appraisal fees, title report fees, and documentation fees.

3.3      Reimbursement  Costs. The Borrowers agree to reimburse the Bank for any
         expenses  it  incurs  in the  preparation  of  this  Agreement  and any
         agreement or instrument  required by this Agreement.  Expenses include,
         but are not limited  to,  reasonable  attorneys'  fees,  including  any
         allocated costs of the Bank's in-house  counsel to the extent permitted
         by applicable law.

4.       DISBURSEMENTS, PAYMENTS AND COSTS

4.1      Disbursements and Payments.

(a)      Each  payment  by the  Borrowers  will  be made  in  U.S.  Dollars  and
         immediately  available  funds by direct  debit to a deposit  account as
         specified  below or, for  payments  not  required  to be made by direct
         debit,  by mail to the address shown on the Borrowers'  statement or at
         one of the Bank's banking centers in the United States.

(b)      Each disbursement by the Bank and each payment by the Borrowers will be
         evidenced  by records kept by the Bank.  In addition,  the Bank may, at
         its  discretion,  require the Borrowers to sign one or more  promissory
         notes.

4.2      Requests for Credit;  Equal Access by all  Borrowers.  If there is more
         than one Borrower,  any Borrower (or a person or persons  authorized by
         any one of the  Borrowers),  acting  alone,  can  borrow up to the full
         amount of credit provided under this  Agreement.  Each Borrower will be
         liable for all  extensions  of credit made under this  Agreement to any
         other Borrower.

4.3      Telephone and Telefax Authorization.

(a)      The Bank may honor  telephone or telefax  instructions  for advances or
         repayments  or for the  designation  of  optional  interest  rates  and
         telefax  requests  for the  issuance  of  letters of credit  given,  or
         purported to be given, by any one of the individuals authorized to sign
         loan  agreements  on  behalf  of  any of the  Borrowers,  or any  other
         individual designated by any one of such authorized signers.

(b)      Advances  will be deposited in and  repayments  will be withdrawn  from
         account  number  14878-03863  owned by  Borrower 1 or such other of the
         Borrowers'  accounts  with the Bank as  designated  in  writing  by the
         Borrowers.

(c)      The  Borrowers  will  indemnify  and hold the  Bank  harmless  from all
         liability,  loss,  and costs in connection  with any act resulting from
         telephone or telefax instructions the Bank reasonably believes are made
         by  any   individual   authorized   by  the   Borrowers  to  give  such
         instructions. This paragraph will survive this Agreement's termination,
         and will benefit the Bank and its officers, employees, and agents.

4.4      Direct Debit (Pre-Billing).

(a)      The  Borrowers  agree that the Bank will debit deposit  account  number
         14878-03863  owned  by  Borrower  1 or  such  other  of the  Borrowers'
         accounts with the Bank as  designated in writing by the Borrowers  (the
         "Designated  Account")  on the  date  each  payment  of  principal  and
         interest and any fees from the Borrowers become due (the "Due Date").

(b)      Prior to each Due Date, the Bank will mail to the Borrowers a statement
         of the amounts that will be due on that Due Date (the "Billed Amount").
         The bill will be mailed a specified  number of  calendar  days prior to
         the Due Date, which number of days will be mutually agreed from time to
         time by the Bank and the Borrowers.  The  calculations in the bill will
         be made on the assumption  that no new extensions of credit or payments
         will be made  between  the date of the  billing  statement  and the Due
         Date,  and that there will be no  changes  in the  applicable  interest
         rate.

(c)      The Bank will  debit the  Designated  Account  for the  Billed  Amount,
         regardless  of  the  actual  amount  due on  that  date  (the  "Accrued
         Amount").  If the  Billed  Amount  debited  to the  Designated  Account
         differs from the Accrued  Amount,  the  discrepancy  will be treated as
         follows:

         (i)      If the  Billed  Amount is less than the  Accrued  Amount,  the
                  Billed  Amount for the following Due Date will be increased by
                  the amount of the  discrepancy.  The Borrowers  will not be in
                  default by reason of any such discrepancy.

                                       5



         (ii)     If the  Billed  Amount is more than the  Accrued  Amount,  the
                  Billed  Amount for the following Due Date will be decreased by
                  the amount of the discrepancy.

         Regardless  of any such  discrepancy,  interest will continue to accrue
         based  on  the  actual   amount  of   principal   outstanding   without
         compounding.  The  Bank  will  not pay the  Borrowers  interest  on any
         overpayment.

(d)      The Borrowers will maintain  sufficient funds in the Designated Account
         to cover each debit. If there are insufficient  funds in the Designated
         Account  on the date the  Bank  enters  any  debit  authorized  by this
         Agreement, the Bank may reverse the debit.

(e)      The Borrowers may terminate  this direct debit  arrangement at any time
         by sending  written notice to the Bank at the address  specified at the
         end of this  Agreement.  If the Borrowers  terminate this  arrangement,
         then the principal amount  outstanding under this Agreement will at the
         option  of the Bank  bear  interest  at a rate per  annum  which is 0.5
         percentage  point higher than the rate of interest  otherwise  provided
         under this Agreement.

4.5      Banking Days.  Unless otherwise  provided in this Agreement,  a banking
         day is a day  other  than a  Saturday,  Sunday  or  other  day on which
         commercial banks are authorized to close, or are in fact closed, in the
         state  where the Bank's  lending  office is  located,  and, if such day
         relates to amounts bearing interest at an offshore rate (if any), means
         any such day on which dealings in dollar  deposits are conducted  among
         banks  in the  offshore  dollar  interbank  market.  All  payments  and
         disbursements  which  would be due on a day which is not a banking  day
         will be due on the next banking  day.  All  payments  received on a day
         which is not a banking  day will be  applied  to the credit on the next
         banking day.

4.6      Interest Calculation. Except as otherwise stated in this Agreement, all
         interest and fees,  if any,  will be computed on the basis of a 360-day
         year and the  actual  number  of days  elapsed.  This  results  in more
         interest or a higher fee than if a 365-day  year is used.  Installments
         of  principal  which are not paid when due under this  Agreement  shall
         continue to bear interest until paid.

4.7      Default Rate.  Upon the occurrence of any default under this Agreement,
         all amounts  outstanding under this Agreement,  including any interest,
         fees or costs  which are not paid when due,  will at the  option of the
         Bank bear interest at a rate which is 2.0 percentage points higher than
         the rate of interest otherwise provided under this Agreement.  This may
         result in compounding of interest. This will not constitute a waiver of
         any default.

5.       CONDITIONS

Before the Bank is  required  to extend any credit to the  Borrowers  under this
Agreement,  it must  receive any  documents  and other  items it may  reasonably

         occurrence of the following event: Facility No. 1 of the Loan Agreement
         dated as of the date hereof between CWSC and the Bank, as now in effect
         or as hereafter  renewed,  amended,  restated or superseded (the "Other
         Credit  Facility"),  terminates  for  any  reason,  including,  without
         limitation,  termination of the Other Credit Facility at the request of
         CWSC, termination resulting from failure by the Bank to renew the Other
         Credit Facility,  or termination as otherwise  provided under the Other
         Credit Facility.

8.       DEFAULT AND REMEDIES

If any of the following events of default occurs, the Bank may do one or more of
the  following:  declare the  Borrowers in default,  stop making any  additional
credit  available  to the  Borrowers,  and require the  Borrowers to repay their
entire debt immediately and without prior notice. If an event which, with notice
or the passage of time,  will constitute an event of default has occurred and is
continuing,  the Bank has no obligation  to make  advances or extend  additional
credit under this Agreement.  In addition,  if any event of default occurs,  the
Bank shall have all rights,  powers and remedies available under any instruments
and agreements  required by or executed in connection  with this  Agreement,  as
well as all rights and remedies  available  at law or in equity.  If an event of
default occurs under the paragraph entitled "Bankruptcy," below, with respect to
any  Borrower,  then the  entire  debt  outstanding  under this  Agreement  will
automatically be due immediately.

8.1      Failure  to  Pay.  The  Borrowers  fail to make a  payment  under  this

         substantial portion of any Borrower's or any Obligor's business, or the
         business is  terminated,  or, if any  Obligor is anything  other than a
         natural person, such Obligor is liquidated or dissolved.

8.7      Lawsuits.  Any lawsuit or  lawsuits  are filed on behalf of one or more
         trade  creditors  against any  Borrower or any Obligor in an  aggregate

         Agreement or any such document is no longer in effect, or any guarantor
         purports to revoke or disavow the guaranty.

8.12     ERISA  Plans.  Any one or  more of the  following  events  occurs  with
         respect  to a Plan  of any  Borrower  subject  to  Title  IV of  ERISA,
         provided  such event or events could  reasonably  be  expected,  in the
         judgment of the Bank,  to subject any  Borrower to any tax,  penalty or
         liability  (or  any  combination  of  the  foregoing)   which,  in  the
         aggregate,  could  have a  material  adverse  effect  on the  financial
         condition of such Borrower:

         Borrower (or any other party named in the Covenants  section) to comply
         with the financial covenants set forth in this Agreement,  whether such
         failure is evidenced by financial  statements  delivered to the Bank or
         is otherwise known to the Borrowers or the Bank.

8.14     Restrictive  Covenant.  Borrower 1 directly or indirectly agrees to any
         arrangement  whereby  the  ability  of any of its  subsidiaries  to pay
         dividends to Borrower 1 is restricted.

         information  provided to the Bank and all financial  covenants  will be
         made  under  generally  accepted  accounting  principles,  consistently
         applied.

9.2      California Law. This Agreement is governed by California state law.

                                       11



9.3      Successors and Assigns. This Agreement is binding on the Borrowers' and
         the Bank's successors and assignees.  The Borrowers agree that they may
         not assign this Agreement  without the Bank's prior  consent.  The Bank
         may sell  participations  in or  assign  this  loan,  and may  exchange
         financial  information  about the  Borrowers  with actual or  potential
         participants or assignees.  If a  participation  is sold or the loan is
         assigned,  the  purchaser  will have the right of set-off  against  the
         Borrowers.

9.4      Arbitration and Waiver of Jury Trial

(a)      This paragraph  concerns the resolution of any  controversies or claims
         between the parties,  whether arising in contract,  tort or by statute,
         including but not limited to  controversies or claims that arise out of
         or relate to: (i) this agreement (including any renewals, extensions or
         modifications);   or  (ii)  any  document  related  to  this  agreement
         (collectively  a  "Claim").   For  the  purposes  of  this  arbitration
         provision   only,   the  term   "parties"   shall  include  any  parent
         corporation,  subsidiary  or  affiliate  of the  Bank  involved  in the
         servicing,  management or administration of any obligation described or
         evidenced by this agreement.

(b)      At the  request  of any party to this  agreement,  any  Claim  shall be
         resolved  by  binding   arbitration  in  accordance  with  the  Federal
         Arbitration  Act (Title 9, U. S. Code) (the "Act").  The Act will apply
         even though this agreement provides that it is governed by the law of a
         specified state.

(c)      Arbitration  proceedings will be determined in accordance with the Act,
         the applicable  rules and procedures for the arbitration of disputes of
         JAMS  or  any  successor  thereof  ("JAMS"),  and  the  terms  of  this
         paragraph.  In the  event  of any  inconsistency,  the  terms  of  this
         paragraph shall control.

(d)      The arbitration  shall be  administered  by JAMS and conducted,  unless
         otherwise  required  by law,  in any U. S. state where real or tangible
         personal property  collateral for this credit is located or if there is
         no such collateral, in the state specified in the governing law section
         of this  agreement.  All Claims shall be determined by one  arbitrator;
         however, if Claims exceed Five Million Dollars  ($5,000,000),  upon the
         request of any party, the Claims shall be decided by three arbitrators.
         All arbitration  hearings shall commence within ninety (90) days of the
         demand  for   arbitration   and  close  within   ninety  (90)  days  of
         commencement and the award of the arbitrator(s)  shall be issued within
         thirty  (30)  days  of  the  close  of  the   hearing.   However,   the
         arbitrator(s),   upon  a  showing  of  good   cause,   may  extend  the
         commencement  of the hearing for up to an  additional  sixty (60) days.
         The arbitrator(s)  shall provide a concise written statement of reasons
         for the award.  The  arbitration  award may be  submitted  to any court
         having jurisdiction to be confirmed and enforced.

(e)      The  arbitrator(s)  will have the authority to decide whether any Claim
         is barred by the  statute of  limitations  and,  if so, to dismiss  the
         arbitration  on that  basis.  For  purposes of the  application  of the
         statute of limitations, the service on JAMS under applicable JAMS rules
         of a notice of Claim is the equivalent of the filing of a lawsuit.  Any
         dispute  concerning  this  arbitration  provision or whether a Claim is
         arbitrable shall be determined by the arbitrator(s).  The arbitrator(s)
         shall have the power to award legal fees  pursuant to the terms of this
         agreement.

(f)      This  paragraph  does not limit the right of any party to: (i) exercise
         self-help  remedies,  such as but not limited to, setoff; (ii) initiate
         judicial  or  non-judicial  foreclosure  against  any real or  personal
         property  collateral;  (iii)  exercise  any  judicial  or power of sale
         rights, or (iv) act in a court of law to obtain an interim remedy, such
         as but  not  limited  to,  injunctive  relief,  writ of  possession  or
         appointment of a receiver, or additional or supplementary remedies.

(g)      The procedure  described above will not apply if the Claim, at the time
         of the proposed submission to arbitration, arises from or relates to an
         obligation to the Bank secured by real  property.  In this case, all of
         the parties to this  agreement  must consent to submission of the Claim
         to  arbitration.  If both  parties do not consent to  arbitration,  the
         Claim will be resolved as follows: The parties will designate a referee
         (or a panel of  referees)  selected  under the  auspices of JAMS in the
         same  manner  as   arbitrators   are  selected  in  JAMS   administered
         proceedings.  The designated referee(s) will be appointed by a court as
         provided  in  California  Code of Civil  Procedure  Section 638 and the
         following  related  sections.  The referee (or presiding referee of the
         panel) will be an active  attorney or a retired  judge.  The award that
         results  from the  decision  of the  referee(s)  will be  entered  as a
         judgment in the court that  appointed the referee,  in accordance  with
         the provisions of California Code of Civil  Procedure  Sections 644 and
         645.

(h)      The filing of a court action is not intended to  constitute a waiver of
         the right of any  party,  including  the  suing  party,  thereafter  to
         require submittal of the Claim to arbitration.

                                       12



(i)      By  agreeing  to  binding  arbitration,  the  parties  irrevocably  and
         voluntarily waive any right they may have to a trial by jury in respect
         of any Claim.  Furthermore,  without intending in any way to limit this
         agreement to arbitrate, to the extent any Claim is not arbitrated,  the
         parties  irrevocably and voluntarily waive any right they may have to a
         trial by jury in respect of such Claim.  This  provision  is a material
         inducement for the parties entering into this agreement.

9.5      Severability;   Waivers.   If  any  part  of  this   Agreement  is  not
         enforceable,  the  rest of the  Agreement  may be  enforced.  The  Bank
         retains all rights,  even if it makes a loan after default. If the Bank
         waives a default, it may enforce a later default. Any consent or waiver
         under this Agreement must be in writing.

9.6      Attorneys'  Fees.  The  Borrowers  shall  reimburse  the  Bank  for any
         reasonable costs and attorneys' fees incurred by the Bank in connection
         with the  enforcement or  preservation  of any rights or remedies under
         this Agreement and any other documents executed in connection with this
         Agreement,  and in connection with any amendment,  waiver, "workout" or
         restructuring  under  this  Agreement.  In the  event of a  lawsuit  or
         arbitration  proceeding,  the  prevailing  party is entitled to recover
         costs and reasonable  attorneys'  fees incurred in connection  with the
         lawsuit  or  arbitration  proceeding,  as  determined  by the  court or
         arbitrator.  In the event that any case is  commenced by or against any
         Borrower  under the  Bankruptcy  Code (Title 11, United States Code) or
         any similar or successor statute, the Bank is entitled to recover costs
         and  reasonable  attorneys'  fees  incurred by the Bank  related to the
         preservation,  protection,  or enforcement of any rights of the Bank in
         such a case. As used in this paragraph,  "attorneys' fees" includes the
         allocated costs of the Bank's in-house counsel.

9.7      Joint and Several Liability.  This paragraph shall apply if two or more
         Borrowers sign this Agreement:

(a)      Each  Borrower  agrees that it is jointly and  severally  liable to the
         Bank for the payment of all  obligations  arising under this Agreement,
         and that such liability is independent of the  obligations of the other
         Borrower(s).  Each obligation,  promise,  covenant,  representation and
         warranty in this Agreement shall be deemed to have been made by, and be
         binding upon, each Borrower,  unless this Agreement  expressly provides
         otherwise.  The Bank may bring an action against any Borrower,  whether
         an action is brought against the other Borrower(s).

(b)      Each Borrower agrees that any release which may be given by the Bank to
         the other  Borrower(s)  or any guarantor will not release such Borrower
         from its obligations under this Agreement.

(c)      Each Borrower  waives any right to assert against the Bank any defense,
         setoff,  counterclaim,  or claims which such  Borrower may have against
         the other  Borrower(s)  or any other  party  liable to the Bank for the
         obligations of the Borrowers under this Agreement.

(d)      Each Borrower  waives any defense by reason of any other  Borrower's or
         any other person's defense,  disability, or release from liability. The
         Bank can exercise its rights  against each  Borrower  even if any other
         Borrower or any other  person no longer is liable  because of a statute
         of limitations or for other reasons.

(e)      Each Borrower  agrees that it is solely  responsible for keeping itself
         informed as to the financial  condition of the other Borrower(s) and of
         all circumstances which bear upon the risk of nonpayment. Each Borrower
         waives any right it may have to require  the Bank to  disclose  to such
         Borrower any  information  which the Bank may now or hereafter  acquire
         concerning the financial condition of the other Borrower(s).

(f)      Each Borrower waives all rights to notices of default or nonperformance
         by any other  Borrower  under this  Agreement.  Each  Borrower  further
         waives all rights to notices of the  existence  or the  creation of new
         indebtedness  by any other Borrower and all rights to any other notices
         to any party liable on any of the credit extended under this Agreement.

(g)      The  Borrowers  represent and warrant to the Bank that each will derive
         benefit,  directly and indirectly,  from the collective  administration
         and  availability of credit under this  Agreement.  The Borrowers agree
         that the Bank will not be required to inquire as to the  disposition by
         any Borrower of funds  disbursed in  accordance  with the terms of this
         Agreement.

(h)      Until all obligations of the Borrowers to the Bank under this Agreement
         have been paid in full and any  commitments  of the Bank or  facilities
         provided by the Bank under this  Agreement have been  terminated,  each
         Borrower   (a)   waives  any  right  of   subrogation,   reimbursement,
         indemnification and contribution (contractual, statutory or otherwise),
         including without  limitation,  any claim or right of subrogation under
         the  Bankruptcy  Code (Title 11,  United  States Code) or any successor
         statute,  which such  Borrower  may now or  hereafter  have against any
         other  Borrower with respect to the  indebtedness  incurred  under this
         Agreement;  (b) waives any right to enforce  any remedy  which the Bank
         now has or may hereafter  have against any other  Borrower,  and waives
         any benefit of, and any right to  participate  in, any  security now or
         hereafter held by the Bank.

                                       13



(i)      Each Borrower  waives any right to require the Bank to proceed  against
         any other Borrower or any other person;  proceed against or exhaust any
         security;  or pursue any other remedy.  Further, each Borrower consents
         to the taking of, or failure  to take,  any action  which  might in any
         manner or to any  extent  vary the risks of the  Borrowers  under  this
         Agreement  or  which,  but  for  this  provision,  might  operate  as a
         discharge of the Borrowers.

9.8      One  Agreement.  This  Agreement  and any  related  security  or  other
         agreements required by this Agreement, collectively:

(a)      represent the sum of the understandings and agreements between the Bank
         and the Borrowers concerning this credit;

(b)      replace any prior oral or written  agreements  between the Bank and the
         Borrowers concerning this credit; and

(c)      are intended by the Bank and the  Borrowers as the final,  complete and
         exclusive statement of the terms agreed to by them.

In the event of any conflict  between this  Agreement  and any other  agreements
required by this  Agreement,  this Agreement will prevail.  Any reference in any
related  document to a "promissory  note" or a "note"  executed by the Borrowers
and  dated as of the date of this  Agreement  shall be  deemed  to refer to this
Agreement, as now in effect or as hereafter amended, renewed, or restated.

9.9      Indemnification.  The  Borrowers  will  indemnify  and  hold  the  Bank
         harmless from any loss, liability, damages, judgments, and costs of any
         kind  relating  to or arising  directly or  indirectly  out of (a) this
         Agreement or any document required  hereunder,  (b) any credit extended
         or  committed  by the  Bank  to the  Borrowers  hereunder,  and (c) any
         litigation or proceeding  related to or arising out of this  Agreement,
         any such  document  or any such  credit;  provided,  however,  that the
         Borrowers  shall have no such  obligation to indemnify or hold the Bank
         harmless  to the extent such loss,  liability,  damages,  judgments  or
         costs result from the gross  negligence  or willful  misconduct  of the
         Bank, its officers, agents or employees. This indemnity includes but is
         not  limited  to  attorneys'  fees  (including  the  allocated  cost of
         in-house  counsel).  This  indemnity  extends to the Bank,  its parent,
         subsidiaries and all of their directors,  officers,  employees, agents,
         successors,   attorneys,  and  assigns.  This  indemnity  will  survive
         repayment of the  Borrowers'  obligations  to the Bank. All sums due to
         the Bank  hereunder  shall be  obligations  of the  Borrowers,  due and
         payable immediately without demand.

9.10     Notices.  Unless  otherwise  provided in this  Agreement  or in another
         agreement  between the Bank and the  Borrowers,  all  notices  required
         under this  Agreement  shall be  personally  delivered or sent by first
         class mail, postage prepaid,  or by overnight courier, to the addresses
         on the signature  page of this  Agreement,  or sent by facsimile to the
         fax numbers listed on the signature page, or to such other addresses as
         the Bank and the  Borrowers  may specify  from time to time in writing.
         Notices and other communications shall be effective (i) if mailed, upon
         the earlier of receipt or five (5) days after deposit in the U.S. mail,
         first class, postage prepaid, (ii) if telecopied,  when transmitted, or
         (iii) if hand-delivered,  by courier or otherwise  (including telegram,
         lettergram or mailgram), when delivered.

9.11     Headings.  Article and paragraph  headings are for  reference  only and
         shall not affect the  interpretation  or meaning of any  provisions  of
         this Agreement.

9.12     Counterparts. This Agreement may be executed in as many counterparts as
         necessary  or  convenient,  and by the  different  parties on  separate
         counterparts  each of  which,  when so  executed,  shall be  deemed  an
         original but all such  counterparts  shall  constitute  but one and the
         same agreement.

9.13     Prior Agreement Superseded. This Agreement supersedes the Business Loan
         Agreement  entered into as of February  28, 2003,  between the Bank and
         the Borrowers, and any credit outstanding thereunder shall be deemed to
         be outstanding under this Agreement.

9.14     Commitment  Expiration.  The Bank's  commitment  to extend credit under
         this Agreement will expire on December 24, 2004,  unless this Agreement
         and any  documents  required  by this  Agreement  have been  signed and
         returned to the Bank on or before that date.

                                       14



This Agreement is executed as of the date stated at the top of the first page.
