                           SJW CORP. AND SUBSIDIARIES
         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1.   General
          -------

In the opinion of SJW Corp., the accompanying  unaudited condensed  consolidated
financial  statements  contain  all  adjustments,   consisting  only  of  normal
recurring  adjustments,  necessary for the fair  presentation of the results for
the interim periods.

The Notes to Consolidated Financial Statements in SJW Corp.'s 2005 Annual Report
on Form  10-K for the year  ended  December  31,  2005,  should be read with the
accompanying condensed consolidated financial statements.

Water  sales are  seasonal  in  nature.  The demand  for  water,  especially  by
residential customers, is generally influenced by weather conditions. The timing
of precipitation  and climactic  conditions can cause seasonal water consumption
by residential  customers to vary  significantly.  Due to the seasonal nature of
the water business, the operating results for interim periods are not indicative
of the operating results for a twelve-month period.  Revenue is generally higher
in the warm,  dry summer months when water usage and sales are greater and lower
in the winter when cooler  temperatures  and  increased  rainfall  curtail water
usage and sales.

Basic earnings per share and basic comprehensive income per share are calculated
using  income  available  to  common  shareholders  and  comprehensive   income,
respectively,  divided  by the  weighted  average  number of shares  outstanding
during the period.  Diluted earnings per share and dilutive comprehensive income
per share are  calculated  using  income  available to common  shareholders  and
comprehensive  income  divided by the weighted  average  number of common shares
including both shares outstanding and shares potentially  issuable in connection
with stock options, restricted stock awards and deferred restricted common stock
awards granted under SJW Corp.'s  Long-Term  Incentive Plan (the Incentive Plan)
and awards granted under the Employee Stock Purchase Plan.

For the three months ended March 31, 2006 and 2005, the basic  weighted  average
number of common shares was 18,271,270  and  18,271,026,  respectively.  For the
three months ended March 31, 2006 and 2005, the diluted  weighted average number
of common shares  outstanding was 18,530,097 and 18,441,938,  respectively.  For
the three months  ended March 31, 2006,  28,164  option share  equivalents  were
excluded from the dilutive calculation because they were anti-dilutive.

On January 31, 2006, the Board of Directors of SJW Corp.  approved a two-for-one
stock split of common stock. The two-for-one  stock split was effective on March
2, 2006.  Basic and diluted earnings and  comprehensive  income per share in the
current and prior periods reflect the impact of the stock split.

NOTE 2.   Long-Term Incentive Plan
          ------------------------

     Common Shares
     -------------

On April 29,  2003,  SJW  Corp.'s  shareholders  approved  an  amendment  to its
Long-Term Incentive Plan (Incentive Plan), which was originally adopted on April
18, 2002.  Under the Incentive Plan,  1,800,000 common shares have been reserved
for  issuance.  The  amendment to the Incentive  Plan  includes  terms  allowing
non-employee directors to receive awards,  authorizing the plan administrator to
grant  stock  appreciation  rights,  and listing the  performance  criteria  for
performance  shares.  The amended Incentive Plan allows SJW Corp. to provide key
employees,  including officers, and non-employee  directors,  the opportunity to
acquire an equity  interest in SJW Corp. A  participant  in the  Incentive  Plan
generally may not receive  awards under the Incentive Plan covering an aggregate
of more than 600,000  common shares in any calendar year.  Additionally,  awards
granted  under the  Incentive  Plan may be  conditioned  upon the  attainment of
specified  performance goals. The types of awards included in the Incentive Plan
are stock options,  dividend units,  performance  shares,  and rights to acquire
restricted  stock and stock  bonuses.  As of March 31, 2006,  18,612 shares have
been issued pursuant to the Incentive Plan, and 397,146 shares are issuable upon
the  exercise  of  outstanding  options,  restricted  stock  units and  deferred
restricted  stock units.  The remaining  shares available for issuance under the
Incentive  Plan are  1,384,242.  The total  compensation  cost charged to income
under the Incentive Plan for the three months ended March 31, 2006 and March 31,
2005 was $218,000 and $340,000  respectively,  inclusive of dividend  equivalent
rights.  The  total  benefit,   including   non-employee   directors'  converted
post-retirement  benefits,  recorded in shareholders' equity under the Incentive
Plan for the three months ended March 31, 2006 and March 31, 2005 was  $359,000,
and $453,000, respectively.

     Stock Options
     -------------

Awards in the form of stock option  agreements  under the  Incentive  Plan allow
executives to purchase common shares at a specified  price.  Options are granted
at an  exercise  price that is not less than the per share  market  price on the
date of the grant. Options vest at a 25% on each annual date over four years and
are exercisable over a 10-year period.  No options were granted during the three
month  period  ending  March 31,  2006.  During the three months ended March 31,
2006, 550 shares were exercised by a former  employee,  including 20 shares from
vested dividend  equivalent rights.  Shares subject to outstanding options under
the  Incentive  Plan were 163,470 and 152,698 as of March 31, 2006 and March 31,
2005, respectively.

At the  beginning  of  2006,  SJW  Corp.  has  adopted  Statement  of  Financial
Accounting Standards (SFAS) No. 123R,  Share-Based Payment (Statement 123R), for
all existing  and new  share-based  compensation  plans in  accordance  with the
modified  prospective   transition  method.   Previously,   SJW  Corp.  followed
accounting interpretations, as permitted by SFAS 123, Accounting for Stock-Based
Compensation (Statement 123), in accounting for share-based  compensation plans.
To  estimate  the fair  value of  options  at grant  date as the  basis  for the

                                       7

stock-based   compensation   awards,   SJW  Corp.   utilizes  the  Black-Scholes
option-pricing model, which requires the use of subjective assumptions. Further,
as required under  Statement  123R, SJW Corp. now estimates  forfeitures for the
share-based  awards that are not  expected to vest.  Changes in these inputs and
assumptions  can affect the measure of estimated  fair value of our  share-based
compensation. The weighted average assumptions utilized include:

                                                     2006        2005      2004
                                                     ----        ----      ----
Expected dividend yield                               n.a.        2.6%      3.3%
Expected volatility                                   n.a.       24.3%     23.6%
Risk-free interest rate                               n.a.       3.67%     3.22%
Expected holding period in years                      n.a.        5.0       5.0

For the quarter  ended March 31,  2006,  after  taking  into  consideration  the
relevant facts and  circumstances,  SJW Corp.  does not project any  foreseeable
terminations  which could lead to forfeiture of unvested options.  SJW Corp. has
recognized share based compensation  expense for the stock options granted under
the Incentive Plan of $33,000 and $28,000,  for the three months ended March 31,
2006 and March 31, 2005, respectively.  A summary of  the status of  SJW Corp.'s
stock options  as of March 31, 2006 and changes during  the  three month  period
ending March 31, 2006, are shown below.

                                       8


As of March 31, 2006,  total  unrecognized  compensation  costs related to stock
options  amounted to $271,000.  These costs are expected to be recognized over a
weighted-average period of 2.08 years.

     Restricted Stock and Deferred Restricted Stock Plans
     ----------------------------------------------------

On January 30, 2006,  restricted  stock units for 14,000  shares of common stock
were  granted to a key  employee of SJW Corp.,  which vest over a period of four
years,  as services are rendered.  The  restricted  stock units were valued at a
market price of $25.29 per share at the date of grant and will be  recognized as
share based  compensation  expense over the vesting period. For the three months
ended  March 31,  2006,  $15,000 has been  recorded as share based  compensation
expense for this grant.

On June 27, 2003,  deferred  restricted  stock units for 83,340 shares of common
stock were granted to a key  employee of SJW Corp.,  which vest over a period of
three years and are redeemable upon retirement.  The deferred  restricted  stock
units  were  valued at the  market  price of $14.05 per share at the date of the
grant, which is being recognized as stock compensation  expense over the vesting
period. For the three months ended March 31, 2006 and 2005, compensation expense
related to these  deferred  restricted  stock units  amounted to $0 and $117,000
respectively.

SJW Corp.  has (i) a Deferred  Restricted  Stock Program  ("Stock  Program") for
non-employee  Board members whereby  non-employee Board members were entitled in
2003 to elect to convert  their  existing  cash pension  benefit  into  deferred
restricted stock units and whereby certain  directors will receive annual grants
of deferred  restricted  stock units,  and (ii) a Deferral  Election Program for
non-employee  Board members  ("Deferral  Program")  whereby members can elect to
convert their annual  retainer fees into deferred  restricted  stock units.  The
number of shares of each annual deferred  restricted stock award is equal to the
annual retainer fee as of the date of grant divided by (i) the fair market value
of SJW Corp.'s common stock on the date of grant under the Stock Program or (ii)
the fair market value of SJW Corp.'s common stock as of the last business day of
the year under the Deferral Program.

On September 1, 2003,  deferred  restricted  stock units covering 111,048 shares
were granted to non-employee Board members who elected to receive their existing
and future cash pension  benefits in deferred  restricted stock awards under the
Deferred  Restricted Stock Program at the market price of $14.20 per share. With
respect to the  conversion  of existing  pension  benefits,  which were  accrued
before the grant date,  40,974 shares were fully vested at the time of grant and
the remaining  70,074 shares vest over a period of three years when services are
rendered. As of March 31, 2006, a total of 15,978 shares were issued pursuant to
deferred   restricted  stock  awards  under  the  Stock  Program  to  a  retired
non-employee board member. As of March 31, 2006, total vested shares are 73,174.
In  accordance  with  Statement  123R,  SJW  Corp.  has  recognized  share-based
compensation  expense of $87,000 and  $87,000,  for the three months ended March
31, 2006 and 2005,  respectively,  related to deferred  restricted  stock awards
under the Deferred Restricted Stock Program.

                                        9


Directors  who elect to convert  their  annual  retainer  fee  receive  deferred
restricted  stock units in an amount equal to the annual retainer fee divided by
the fair  market  value of SJW Corp.'s  common  stock on the last  business  day
before  the date of grant.  These  deferred  restricted  stock  units  vest on a
monthly basis over the annual period in which the retainer  would have otherwise
been earned.

In January 2006,  deferred  restricted  stock units  covering  4,744 shares were
issued to the  non-employee  Board  members who elected to convert  their annual
retainer  fee at a  conversion  price of  $22.75  per share  under the  Deferral
Program.  As of March 31, 2006 and 2005, SJW Corp.  granted deferred  restricted
stock  awards  for  20,520  and  15,776  shares in lieu of cash  retainer  fees,
respectively.  SJW Corp.  has  recognized  share-based  compensation  expense of
$27,000  and  $27,000  for the  three  months  ended  March  31,  2006 and 2005,
respectively,   related  to  deferred   restricted   stock  awards   granted  to
non-employee Board members in connection with their annual retainers.  A summary

of March 31, 2006 and changes  during the three month  period  ending  March 31,
2006, are shown below.

     Dividend Equivalent Rights
     --------------------------

Under the  Incentive  Plan,  holders of options,  restricted  stock and deferred
restricted  stock awards have the right to receive  dividend  rights each time a
dividend  is paid on common  shares  after the grant  date.  Stock  compensation
expense on dividend  equivalent rights is expenses and recognized as a liability
on the date  dividends  are  issued.  The stock  compensation  expense  on stock
options and deferred restricted stock awards reported above in this note include
the share-based compensation expenses accrued on the dividend equivalent rights.
As of March 31,  2006 and 2005,  a  cumulative  of 21,296  and  12,722  dividend
equivalent rights were converted,  since inception, to deferred restricted stock
awards,  respectively,  and $56,000 and $49,000  related to dividend  equivalent
rights were accrued as a liability, respectively.

     Employee Stock Purchase Plan
     ----------------------------

The Employee  Stock  Purchase  Plan (ESPP) was approved by the  shareholders  on
April 28, 2005, and permits eligible  employees to purchase SJW Corp. stock at a
discounted price. Shares of common stock are offered for purchase under the ESPP
through a series  of  successive  offering  periods  until  such time as (i) the
maximum  number of shares of common stock  available for issuance under the ESPP
shall have been  purchased  or (ii) the ESPP is  terminated.  A total of 270,400
shares of common stock have been reserved for issuance under the ESPP.

The ESPP allows  employees to designate up to a maximum  of 10 percent  (10%) of
their base compensation,  subject to certain restrictions, to purchase shares of
common stock at 85% of the fair market value of shares on the purchase date. The
first purchase  interval in effect under the ESPP began on February 1, 2006, and
will end on July 31, 2006. The ESPP has no look-back provisions. As of March 31,
2006, cash received from employees towards the ESPP amounted to $79,895.

Share-based  compensation cost for awards granted under ESPP of $13,977 has been
recognized  for the three  months ended March 31, 2006,  after  considering  the
estimated employee terminations or withdrawals from the plan before the purchase
date.  For the quarter ended March 31, 2006,  adoption of Statement 123R lowered
the SJW Corp.'s  earnings  from  continuing  operations  before  income taxes by
$13,977.

As of March 31, 2006, total unrecognized compensation costs related to the first
semi-annual  offering  period  ended  July 31,  2006 for the  ESPP  amounted  to
$28,000.  These costs are  expected  to be  recognized  over a  weighted-average
period of 0.33 years.

The stock options,  deferred  restricted  stock  programs,  dividend  equivalent
rights and ESPP's are all offered through SJW Corp.'s Incentive Plan.

NOTE 8.   Sale of Nonutility Property
          ---------------------------

On  January  20,  2006,  SJW  Land  Company  and San  Jose  Water  Company  sold
approximately  one acre of property  and a building  for  $2,850,000.  SJW Corp.
recognized a gain on the sale of the property of approximately  $1,535,000,  net
of tax of approximately  $1,056,000. On February 1, 2006, San Jose Water Company

$2,668,000.

                                       14

NOTE 9.   Acquisition
          -----------

On October 4, 2005,  SJWTX  Water,  Inc.  (SJWTX  Water),  a newly  formed Texas
corporation and wholly owned subsidiary of SJW Corp.,  entered into an agreement
to  purchase  substantially  all of the  assets  of  Canyon  Lake  Water  Supply
Corporation  (CLWSC),  a Texas  nonprofit water supply  corporation.  CLWSC is a
member-owned  nonprofit water utility headquartered in Canyon Lake, Texas. CLWSC
serves a population of approximately  20,000 with more than 6,700 connections in
western Comal County and southern Blanco County, which is approximately 50 miles
Southwest of Austin,  Texas.  Members of CLWSC approved the purchase on November
5, 2005. The purchase price of CLWSC consists of $3.2 million in cash payable to
CLWSC at closing,  SJWTX Water's  assumption,  retirement or recapitalization of
all of  CLWSC's  outstanding  debt and bond  obligations  of  approximately  $20
million and SJWTX Water's  payment of certain  CLWSC  transaction  expenses.  On
February 14, 2006, the Texas Water  Development  Board  authorized the Executive
administrator  to  negotiate  a  purchase  agreement  for the sale of CLWSC loan
portfolio to SJWTX Water. The acquisition is pending governmental  approval from
the regulatory agencies which is expected to be completed in mid-2006.


NOTE 10.  Subsequent Event
          ----------------

On April 17,  2006,  SJW Land Company and San Jose Water  Company,  wholly-owned
subsidiaries   of  SJW  Corp.,   entered  into  agreements  with  Adobe  Systems
Incorporated  (Adobe) for Adobe to purchase an  aggregate of  approximately  5.5
acres of property located in San Jose,  California for a total purchase price of
approximately  $25,000,000.  The  agreement  between San Jose Water  Company and
Adobe  includes an option for San Jose Water Company to lease-back the buildings
and designated parking until June 2008. Since San Jose Water Company will retain
more than a minor portion of the use of the property, the property will continue
to be classified as utility plant, rather than an asset held-for-sale, until the
transaction is completed.  In accordance with Statement of Financial  Accounting
Standards  No. 144,  Accounting  for the  Impairment  of Disposal of  Long-Lived
Assets, (SFAS 144), SJW Corp. classified the carrying cost of the property under
the SJW Land Company agreement as long-term assets held-for-sale.  The agreement
calls  for  three  separate  contingency  periods during which  certain  closing
conditions must be met. As such, SJW Corp.  cannot  determine the estimated gain
from the sale of property owned by SJW Land Company  agreement until the closing
contingencies are removed.

General:
--------

SJW Corp. is a holding company with four subsidiaries.

San Jose Water  Company,  a wholly owned  subsidiary  of SJW Corp.,  is a public
utility  in  the  business  of  providing  water  service  to  a  population  of
approximately one million people in an area comprising about 138 square miles in
the metropolitan San Jose area.

The  principal  business of San Jose Water Company  consists of the  production,
purchase, storage, purification, distribution and retail sale of water. San Jose
Water Company  provides  water service to customers in portions of the cities of
Cupertino and San Jose and in the cities of Campbell, Monte Sereno, Saratoga and
the Town of Los Gatos, and adjacent unincorporated  territory, all in the County
of Santa Clara in the State of  California.  San Jose Water Company  distributes
water to customers in accordance  with accepted  water  utility  methods,  which
include  pumping from storage and gravity feed from high  elevation  reservoirs.
San Jose Water Company also provides  nonregulated  water related services under
agreements with municipalities.  These nonregulated  services include full water
system operations, billing and cash remittance services.

SJW Land  Company,  a wholly owned  subsidiary  of SJW Corp.,  owns and operates
parking  facilities,  which are  located  adjacent  to San Jose Water  Company's
headquarters and the HP Pavilion in San Jose, California.  SJW Land Company also
owns  commercial  buildings,  other  undeveloped  land primarily in the San Jose
Metropolitan  area,  some  properties in the states of Florida,  Connecticut and
Texas,  and a 70% limited  partnership  interest in 444 West Santa Clara Street,
L.P.  The limited  partnership  has been  determined  to be a Variable  Interest
Entity  within the scope of FIN 46R, and as a result,  it had been  consolidated
with SJW Land Company.

                                       16

Crystal Choice Water Service LLC, a subsidiary  75% owned by SJW Corp.,  engages
in the sale and rental of water conditioning and purification equipment.

In the third quarter of 2005, SJW Corp. formed a Texas corporation, SJWTX Water,
Inc.  (SJWTX  Water).  SJWTX Water has  entered  into an  agreement  to purchase
substantially  all the  assets of  Canyon  Lake  Water  Supply  Corporation,  as
discussed in Item 1, Note 9 of SJW Corp.'s accompanying  consolidated  financial
statements.

SJW Corp. also owns 1,099,952  shares of California  Water Service Group,  which
represents approximately 6% of its outstanding shares as of March 31, 2006.

Business Strategy:
------------------

SJW Corp. focuses its business initiatives in four strategic areas:

     (1)  Regional  regulated  utility  operations in the San Jose  metropolitan
          area.

     (2)  Regional  nonregulated water and utility-related  services provided in
          accordance with the guidelines established by the CPUC.

     (3)  Real estate development and investment activities in SJW Land Company.

     (4)  Out-of-region  water and  utility-related  services,  primarily in the
          Western United States.

     Regional Regulated Activities
     -----------------------------

SJW Corp.'s  regulated  utility  operation is  conducted  through San Jose Water
Company,  a wholly owned water utility subsidiary that provides water service to
the  greater  metropolitan  San  Jose  area.  SJW  Corp.  plans  and  applies  a
disciplined   approach  to   improving   and   maintaining   its  water   system
infrastructure.  It also seeks to acquire regulated water systems adjacent to or
near its existing service territory.

     Regional Nonregulated Activities
     --------------------------------

Operating in accordance with guidelines  established by the CPUC, San Jose Water
Company   provides   nonregulated   water   services   under   agreements   with
municipalities and other utilities.  Nonregulated  services include water system
operations,  billings and cash remittance processing,  maintenance services, and
telecommunication antenna leasing.

San  Jose  Water   Company   also  seeks   appropriate   nonregulated   business
opportunities that complement its existing operations or that allow it to extend
its core competencies beyond existing  operations.  San Jose Water Company seeks
opportunities  to fully  utilize  its  capabilities  and  existing  capacity  by
providing  services to other  regional  water  systems,  benefiting its existing
regional customers through increased efficiencies and revenue sharing.

                                       17


     Real Estate Development and Investment
     --------------------------------------

SJW Land Company's real estate  investments  diversifies  SJW Corp.'s asset base
and balances SJW Corp.'s  concentration  in regulated  assets.  SJW Land Company
implements its strategy by exchanging selected real estate assets for relatively
low risk investments  with a capital  structure and risk and return profile that
is  consistent  with SJW Corp.'s  consolidated  capital  structure  and risk and
return profile.

     Out-of-Region Opportunities
     ---------------------------

SJW Corp. is also pursuing  opportunities to participate in out-of-region  water
and utility-related  services,  particularly regulated water businesses,  in the
Western  United  States.  SJW  Corp.   evaluates   possible   out-of-region  and
out-of-state  acquisition  opportunities  that meet SJW Corp.'s  risk and return
profile.

The factors SJW Corp. considers in evaluating such opportunities include:

     *    regulatory environment

     *    synergy potential

     *    general economic conditions

     *    potential profitability

     *    additional growth opportunities within the region

     *    water quality and environmental issues; and

     *    capital requirements.

SJW  Corp.  cannot  be  certain  it  will  be  successful  in  consummating  any
transactions relating to such opportunities.  In addition,  any transaction will
involve  numerous  risks.  These include the possibility of paying more than the
value derived from the acquisition,  the assumption of certain known and unknown
liabilities of the acquired assets, the risk of diverting management's attention
from normal daily  operations  of the business,  negative  impact to SJW Corp.'s
financial  condition and  operating  results,  the risks of entering  markets in
which it has no or limited direct prior experience and the potential loss of key
employees  of any  acquired  company.  SJW  Corp.  cannot  be  certain  that any
transaction  will be  successful  and will  not  materially  harm its  operating
results or financial condition.

Critical Accounting Policies:
-----------------------------

SJW Corp. has identified the accounting  policies below as the policies critical
to its business  operations and the  understanding of the results of operations.
The preparation of financial  statements  requires  management to make estimates
and  assumptions  that affect the reported  amounts of assets and liabilities at
the date of the  financial  statements,  and revenues  and  expenses  during the
reporting period. SJW Corp. bases its estimates on historical  experience and on
various  other  assumptions  that  are  believed  to  be  reasonable  under  the

                                       18

circumstances.  The impact and any associated risks related to these policies on
SJW Corp.'s business operations is discussed throughout "Management's Discussion
and  Analysis  of  Financial  Condition  and Results of  Operations"  where such
policies affect SJW Corp.'s reported and expected financial results. SJW Corp.'s
critical accounting policies are as follows:

     Balancing Account
     -----------------

The  CPUC  has  established  the  balancing   account  mechanism  to  track  the
under-collection  and over-collection of CPUC authorized revenue associated with
expense  changes  for  purchased  water,  purchased  power and pump  tax.  Since
balances  are  tracked  and  subject to  approval by the CPUC before they can be
incorporated into rates, San Jose Water Company has not recognized the balancing
account in its financial statements. The balance of the balancing account varies
with the  seasonality of the water utility  business such that during the summer
months when the demand for water is at its peak, the balancing  account tends to
reflect an  under-collection,  while  during the winter  months  when demand for
water  is  relatively   lower,  the  balancing   account  tends  to  reflect  an
over-collection.  Had the  balancing  account been  recognized in San Jose Water
Company's financial statements, San Jose Water Company's retained earnings would
be decreased by the amount of balancing account over-collection, as the case may
be, or  increased  by the amount of  balancing  account  under-collection,  less
applicable taxes.

     Revenue Recognition
     -------------------

SJW Corp.  recognizes its regulated and nonregulated  revenue in accordance with
SEC Staff Accounting  Bulletin 104,  "Revenue  Recognition".

San Jose Water  Company's  revenue from metered  customers  includes  billing to
customers  based on meter  readings  plus an estimate of water used  between the
customers'  last meter reading and the end of the  accounting  period.  San Jose
Water Company reads the majority of its customers'  meters on a bi-monthly basis
and records its revenue  based on its meter  reading  results.  Revenue from the
meter  reading date to the end of the  accounting  period is estimated  based on
historical  usage patterns,  production  records and the effective tariff rates.
The estimate of the unbilled revenue is a management  estimate utilizing certain
sets of  assumptions  and  conditions  which  include the number of days between
meter reads for each billing cycle, the customers'  consumption changes, and San
Jose Water Company's experiences in unaccounted-for  water. Actual results could
differ from those  estimates,  which would  result in  adjusting  the  operating
revenue in the period which the revision to San Jose Water  Company's  estimates
are  determined.  As of March 31, 2006 and December 31, 2005,  accrued  unbilled
revenue was $7,437,000 and $8,706,000,  respectively.  Unaccounted-for water for
March  31,  2006  and  2005  approximated  1.8%  and  1.5%,  respectively,  as a
percentage  of  production.  The  estimate  is  based  on the  results  of  past
experience,  the  trend  and  efforts  in  reducing  San  Jose  Water  Company's
unaccounted-for water through customer conservation,  main replacements and lost
water reduction programs.

SJW  Corp.  recognizes  its  nonregulated  revenue  based on the  nature  of the
nonregulated  business  activities.   Revenue  from  San  Jose  Water  Company's
nonregulated  utility  operations  and  billing or  maintenance  agreements  are
recognized  in  accordance  with SEC Staff  Accounting  Bulletin  104,  "Revenue
Recognition", when services have been rendered. Revenue from SJW Land Company is
recognized ratably over the term of the lease or when parking services have been
rendered.  Revenue from Crystal  Choice Water  Service LLC is  recognized at the
time of the delivery of water conditioning and purification equipment or ratably
over the term of the lease of the water conditioning and purification equipment.

                                       19


     Recognition of Regulatory Assets and Liabilities
     ------------------------------------------------

Generally  accepted  accounting  principles  for  water  utilities  include  the
recognition  of regulatory  assets and  liabilities as permitted by SFAS No. 71,
"Accounting for the Effects of Certain Types of Regulation".  In accordance with
SFAS No. 71, San Jose Water Company  records  deferred  costs and credits on the
balance  sheet as  regulatory  assets and  liabilities  when it is probable that
these costs and credits will be recovered in the ratemaking  process in a period
different  from when the costs and credits were  incurred.  Accounting  for such
costs and credits is based on management's judgment that it is probable that the
costs  will be  recoverable  in the future  revenue  of San Jose  Water  Company
through the ratemaking process.  The regulatory assets and liabilities  recorded
by San Jose Water Company primarily relate to the recognition of deferred income
taxes for ratemaking  versus tax accounting  purposes.  The  disallowance of any
asset in the future for ratemaking  purposes,  including the deferred regulatory
assets, would require San Jose Water Company to immediately recognize the impact
of the  costs  for  financial  reporting  purposes.  No  disallowance  had to be
recognized as of March 31, 2006 and December 31, 2005. The net regulatory assets
recorded by San Jose Water  Company as of March 31, 2006 and  December  31, 2005
was $13,118,000 and $13,037,000, respectively.

     Income Taxes
     ------------

SJW Corp. estimates its federal and state income taxes as part of the process of
preparing the financial  statements.  The process involves estimating the actual
current tax exposure  together with assessing  temporary  differences  resulting
from different treatment of items for tax and accounting purposes, including the
evaluation  of the treatment  acceptable  in the water utility  industry and its
regulatory  agency.   These  differences  result  in  deferred  tax  assets  and
liabilities,  which are included in the balance sheet. If actual results, due to
changes in regulatory treatment, or significant changes in tax-related estimates
or assumptions or changes in law, differ  materially from these  estimates,  the
provision for income taxes will be materially  impacted.  The effect on deferred
tax assets and  liabilities of a change in tax rates is recognized in the period
that includes the enactment date.

     Pension Accounting
     ------------------

San Jose Water Company  offers a defined  benefit plan,  Supplemental  Executive
Retirement  Plan and certain  post-retirement  benefits  other than  pensions to
employees retiring with a minimum level of service.  Accounting for pensions and
other  post-retirement  benefits  requires an extensive use of assumptions about
the  discount  rate,  expected  return  on  plan  assets,  the  rate  of  future
compensation  increases  received  by the  employees,  mortality,  turnover  and
medical cost increases.

San Jose Water Company,  through its Retirement  Plan  Administrative  Committee
(the  Committee)  managed by  representatives  from the  unions and  management,
establishes  investment  guidelines which specify that  approximately 30% of the
investments are in bonds or cash and the remaining 70% in equity securities.  As
of December 31, 2005, the plan assets  consist of  approximately  22% bonds,  5%

                                       20

cash and 73% equities.  The committee  requires that equities be  diversified by
industry groups to balance for capital appreciation and income. In addition, all
investments are publicly traded. San Jose Water Company uses an expected rate of
return on plan assets of eight  percent (8%) in its actuarial  computation.  The
distribution  of assets is not  considered  highly  volatile  and  sensitive  to
changes in market rates and prices. Furthermore, foreign assets are not included
in the investment profile and thus risk related to foreign exchange  fluctuation
has been eliminated.

The plan assets are marked to market at the  measurement  date.  The  investment
trust  assets  incurred  unrealized  market  losses  in  years  prior  to  2004.
Unrealized  market  losses on  pension  assets are  amortized  over 14 years for
actuarial expense calculation purposes.

San Jose Water Company  utilizes Moody's 'A' and 'Aa' rated bonds in industrial,
utility and financial sectors with outstanding  amounts of $1,000,000 or more in
determining  the  discount  rate  used in  calculating  the  pension  and  other
postretirement  benefit liabilities at the measurement date. For the year ending
December 31, 2005, the composite discount rate used was 5.75%.

     Share Based Compensation Plans
     ------------------------------

SJW Corp.  has a  stockholder-approved  long-term  incentive  plan  that  allows
granting of nonqualified stock options,  performance shares, deferred restricted
stock awards and dividend  awards.  Under the plan, a total of 1,800,000  common
shares have been  authorized for awards and grants.  Effective  January 1, 2006,
SJW Corp. has adopted  Statement of Financial  Accounting  Standards  (SFAS) No.
123R, using the modified  prospective method of transition.  Previously,  awards
were  accounted  for using SFAS No. 123. SJW Corp.  utilizes  the  Black-Scholes
option-pricing  model to compute the fair value of options at grant date and the
fair value of options granted as the basis for the share based  compensation for
financial reporting purposes.

In addition to the option grants,  SJW Corp. has granted  restricted stock units
and deferred  restricted stock units to a key employee of SJW Corp.,  which were
valued at market price at the date of grant.  SJW Corp. is recognizing  the fair
market value of such units  granted as  compensation  expense,  over the vesting
period of three years as services are rendered.

Additionally,  deferred  restricted  stock awards granted to non-employee  board
members from the conversion of cash pension benefits were valued at market price
at the date of grant. SJW Corp. is  correspondingly  recognizing the fair market
value of the unvested  deferred  restricted stock awards granted as compensation
expense, over the vesting period of three years, as services are rendered.

     Consolidation Policy of Majority-Owned Enterprises
     --------------------------------------------------

SJW Corp.  consolidates  its 75%  controlling  interest of Crystal  Choice Water
Service LLC in its Financial  Statement with the 25% minority  interest included
as "other" in the Consolidated Statements of Income and Comprehensive Income and
in "other  noncurrent  liabilities" on the Balance Sheet.  Effective  January 1,

                                       21

2004, SJW Corp. adopted FASB Interpretation No. 46R (FIN 46R), "Consolidation of
Variable Interest Entities".  As a result of the adoption of FASB Interpretation
No. 46R (FIN 46R), "Consolidation  of Variable  Interest  Entities" in 2004, SJW
Corp.  identified  its  investment  in 444 West Santa  Clara  Street,  L.P. as a
variable interest entity with SJW Land Company as the primary  beneficiary.  SJW
Corp.  consolidates its 70% limited partnership interest in 444 West Santa Clara
Street,  L.P.  with  the  30%  minority  interest  included  as  "other"  in the
Consolidated  Statements  of  Income  and  Comprehensive  Income  and in  "other
noncurrent liabilities" on the Balance Sheet.

     Recognition of Gain/Loss on Nonutility Property
     -----------------------------------------------

In compliance with the Uniform System of Accounts (USOA)  prescribed by the CPUC
and conforming to generally  accepted  accounting  principles for rate-regulated
public utilities,  the cost of retired utility plant, including retirement costs
(less salvage),  is charged to accumulated  depreciation  and no gain or loss is
recognized for utility plant used and useful in providing water utility services
to customers.

Nonutility  property in San Jose Water  Company is property that is neither used
nor useful in providing water utility services to customers and is excluded from
the rate base for  rate-setting  purposes.  San Jose  Water  Company  recognizes
gain/loss on  disposition  of nonutility  property in accordance  with CPUC Code
Section 790.  Nonutility  property in SJW Land Company and Crystal  Choice Water
Service LLC consists primarily of land, buildings,  parking facilities and water
conditioning equipment. Net gains or losses from the sale of nonutility property
are  recorded as a  component  of other  income  (expense)  in the  consolidated
statement of income and comprehensive income.

Recent Accounting Pronouncements:
---------------------------------

Effective  January  1,  2006,  SJW Corp.  has  adopted  Statement  of  Financial
Accounting Standards (SFAS) No. 123R,  Share-Based Payment, as discussed in Item
1, Note 2 of SJW Corp.'s accompanying consolidated financial statements.

Liquidity and Capital Resources:
--------------------------------

San Jose Water Company's  budgeted capital  expenditures for 2006,  exclusive of
capital  expenditures  financed  by customer  contributions  and  advances,  are
$39,950,000 with capital  expenditures  concentrated in water main replacements.
Approximately  $18,000,000  will be spent to replace  San Jose  Water  Company's
mains  in  2006.  Year  to  date  capital  expenditures  as of  March  31,  2006
approximate $6,678,000.

San Jose Water Company's  capital  expenditures  are incurred in connection with
normal  upgrading  and  expansion  of  existing  facilities  and to comply  with
environmental regulations. San Jose Water Company expects to incur approximately
$187,000,000 in capital  expenditures,  which includes  replacement of pipes and
mains,  and  maintaining  existing  water  systems,  over the next  five  years,
exclusive  of customer  contributions  and  advances.  San Jose Water  Company's

                                       22


actual capital  expenditures may vary from its projections due to changes in the
expected demand for services, weather patterns, actions by governmental agencies
and general economic conditions.  Total additions to the utility plants normally
exceed company-financed  additions by several million dollars as a result of new
facilities  construction  funded with advances from developers and contributions
in aid of construction.

A  substantial  portion  of San Jose  Water  Company's  distribution  system was
constructed  during the period from 1945 to 1980. San Jose Water Company expects
that expenditure levels for renewal and modernization of this part of the system
will  grow at an  increasing  rate as these  components  reach  the end of their
useful lives.  In most cases,  replacement  cost will  significantly  exceed the
original  installation  cost of the retired assets due to increases in the costs
of goods and services.

As of March 31, 2006, SJW Corp.'s share of capital  investment in Crystal Choice
Water  Service  LLC  approximated  75%.  SJW  Corp.  does  not  expect  to  make
significant cash contributions to Crystal Choice Water Service LLC in 2006.

Historically,  San Jose Water Company's  write-offs for  uncollectible  accounts
represent less than 1% of its total revenue. Management believes it can continue
to collect its accounts receivable balances at its historical collection rate.

Sources of Capital:
-------------------

San Jose Water  Company's  ability to finance future  construction  programs and
sustain dividend  payments depends on its ability to attract external  financing
and  maintain  or  increase  internally  generated  funds.  The  level of future
earnings and the related cash flow from operations is dependent,  in large part,
upon the timing and outcome of regulatory proceedings.

San Jose Water  Company's  financing  activity  is designed to achieve a capital
structure  consistent with regulatory  guidelines of approximately  50% debt and
50%  equity.  As of March 31,  2006,  San Jose Water  Company's  funded debt and
equity were 46.3% and 53.7%, respectively.

Historically, San Jose Water Company's internally generated funds, which include
allowances  for   depreciation   and  deferred   income  taxes,   have  provided
approximately  50% of the cash requirements for San Jose Water Company's capital
expenditures.  Due to its  strong  cash  position  and  low  financial  leverage
condition,  funding for its future capital  expenditure program will be provided
through  internally  generated  funds and long-term debt. San Jose Water Company
and its parent,  SJW Corp.,  do not  currently  anticipate  the  issuance of any
equity to finance future capital expenditures.

San Jose Water Company has outstanding $130,000,000 of unsecured senior notes as
of March  31,  2006.  The  senior  note  agreements  of San Jose  Water  Company
generally  have terms and  conditions  that restrict San Jose Water Company from
issuing  additional  funded debt if (1) the funded debt would exceed  66-2/3% of
total capitalization,  and (2) net income available for interest charges for the
trailing 12 calendar  month period would be less than 175% of interest  charges.
As of March 31, 2006, San Jose Water  Company's  funded  debt was 46.4% of total
capitalization  and the net  income  for the  preceding  12  months  was 487% of
interest charges.

                                       23

San Jose Water Company has a $2,007,000  loan from the Safe Drinking Water State
Revolving  Fund  (SDWSRF)  at a rate of 2.39%.  This loan was funded in 2005 and
requires  semi-annual  principal and interest payments  commencing in July 2006.
San Jose Water Company issued a standby letter of credit with a commercial  bank
in the  amount of  $2,000,000  in  support  of this  loan.  The letter of credit
automatically  renews for one year each December  unless the issuing bank elects
not to renew and the amount of coverage can be reduced as the principal  balance
decreases.

In 2004, the California  Department of Water  Resources  approved San Jose Water
Company's  application for a second loan under the SDWSRF  program.  The loan is
for  approximately  $1,660,000  over a term of 20-years  at an interest  rate of
2.60%.  These funds will be used for water treatment plant  improvements to meet
increasing filtration  standards.  San Jose Water Company expects to receive the
funding of this loan in 2006, when all documentation have been completed.

In  connection  with  the  acquisition  of  two  properties  in  the  states  of
Connecticut  and Florida in April 2003, SJW Land Company  executed  mortgages in
the aggregate  amount of $9,900,000  in April 2003.  The mortgage  loans have an
original maturity of 10 years and are being amortized over 25 years with a fixed
interest  rate of 5.96% and are secured by the two  properties  in the states of
Connecticut and Florida. The loan agreements generally restrict SJW Land Company
from  prepayment  in the first five years and  require  submission  of  periodic
financial reports as part of the loan covenants. The properties were leased to a
multinational organization for a term of 20-years.

The 444 West Santa Clara  Street,  L.P.,  in which SJW Land  Company  owns a 70%
limited partnership  interest,  has a mortgage loan in the outstanding amount of
$4,075,000  as of March 31, 2006.  The mortgage loan is due in April 2011 and is
amortized over 25 years with a fixed  interest rate of 7.80%.  The mortgage loan
is secured by the  partnership's  real property and is  non-recourse to SJW Land
Company.

In  connection  with a nonutility  property  condemnation  that  occurred in the
fourth  quarter  of 2004,  SJW Land  Company  intends  to  identify  replacement
property  and  reinvest  the  proceeds by November 2006, in order to qualify the
transaction under Internal Revenue Code section 1033.

SJW Corp. and its subsidiaries have unsecured lines of credit available allowing
aggregate  short-term  borrowings of up to $30,000,000 at rates that approximate
the  bank's  prime or  reference  rate.  At March 31,  2006,  SJW Corp.  and its
subsidiaries   had  available   unused   short-term  bank  lines  of  credit  of
$30,000,000. The lines of credit will expire on July 1, 2006.

San Jose Water  Company's  water  supply  consists  of  groundwater  from wells,
surface water from watershed run-off and diversion, and imported water purchased
from the SCVWD.  Surface  water is the least  expensive  source of water and its
availability  will  significantly  impact the water  production costs of the San
Jose Water Company.

Water  production for the three months ended March 31, 2006 decreased 27 million
gallons from the same period in 2005. During this period, more surface water was
used when compared to the same period in 2005.

The change in San Jose Water Company's source of supply mix was as follows:

                                                 ==========================

The changes in the source of supply mix were consistent with the changes in the
water production costs.

Non-water production costs include administrative costs which contains costs for
employee  benefits and salaries and wages. The increase in non-water  production
costs for the first quarter of 2006 consisted  principally of: $543,000 increase
in general and  administrative  costs;  which  included a $433,000  increase for
salaries,  benefits and  retirement  costs,  a $153,000  increase for  liability
insurance, a $137,000 increase for professional services, and a $52,000 increase
in other  expenses  offset by a $232,000  refund of 2005  worker's  compensation
premiums. In addition, other operating expenses increased $470,000,  maintenance
expenses increased $267,000,  and other taxes and depreciation expense increased
$225,000. Income tax expense decreased $26,000 in the first quarter of 2006.

Comprehensive  income for the three  months  ended March 31, 2006  increased  by
$4,426,000,  net of taxes,  compared to a loss of $2,777,000,  net of taxes, for
the same period in 2005.  The change was due to an  increase in market  value of
the investment in California Water Service Group.

Factors That May Affect Future Results:
---------------------------------------

     Water Supply and Energy Resources
     ---------------------------------

San Jose Water  Company's  water  supply is obtained  from  wells,  groundwater,
watershed  run-off and  diversion,  surface water and by import water  purchases
from the SCVWD under the terms of a master contract with SCVWD expiring in 2051.
Groundwater level in 2006 remains slightly higher than the 30-year normal level.

On April 3, 2006,  the  SCVWD's  10  reservoirs  were  93.7%  full with  158,344
acre-feet  of water in storage.  The rainfall in the season  commencing  July 1,
2005 was approximately 124% of historical season average.

Rainfall at San Jose Water  Company's  Lake Elsman was  measured at 51.59 inches
for the season of July 1, 2005 through  March 31, 2006,  which is  approximately
138.2% of the five-year average.  Local surface water is a less costly source of
water  and its  availability  significantly  impacts  San Jose  Water  Company's
results of operations.

                                       27


Based on information  provided by SCVWD in its Water Utility  Enterprise Report,
San Jose Water  Company  believes  that its various  sources of water supply are
sufficient to meet customer demand for the remainder of the year.

To the extent that San Jose Water  Company has to pump water during peak periods
to satisfy  customer demand when imported water is not available,  higher energy
costs will be incurred.  Currently,  the CPUC has no  established  procedure for
water   utilities  to  recover  the  additional   costs  incurred  due  to  such
unanticipated  changes in water supply mix.  There can be no assurance that such
costs will be recovered in full or in part.

     Security Issues
     ---------------

San Jose Water Company has taken steps to increase security at its water utility
facilities and continues to implement a comprehensive  security  upgrade program
for  production  and  storage  facilities,  booster  pump  stations  and company
buildings.  San Jose  Water  Company  also  coordinates  security  and  planning
information  with eight  other large  regional  water  utilities  within the San
Francisco  Bay  area,  as  well as  various  governmental  and  law  enforcement
agencies.

San Jose Water  Company  conducted a  system-wide  vulnerability  assessment  in
compliance with federal regulations that Public Law 107-188 imposed on all water
utilities.  The  assessment  report was filed with the  government  on March 31,
2003. The vulnerability  assessment identified system security enhancements that
impact  water  quality,  health,  safety  and  continuity  of  service  totaling
approximately  $2,300,000.  San Jose  Water  Company  is  completing  the  final
implementation  of security  related  capital  improvements  and as of March 31,
2006,  $2,243,000  has been  incurred  to date on this  project.  San Jose Water
Company has and will continue to bear costs associated with additional  security
precautions to protect its water utility business and other operations. San Jose
Water Company  actively  participated in the security  vulnerability  assessment
training offered by the American Water Works Association Research Foundation and
the Environmental Protection Agency.

     Regulatory Affairs
     ------------------

Almost all of the operating  revenue of San Jose Water Company  results from the
sale of water at rates  authorized  by the CPUC.  The CPUC sets  rates  that are
intended to provide revenue sufficient to recover operating expenses and produce
a reasonable return on common equity. The timing of rate decisions could have an
impact on the results of operations.

On August 19, 2004, the CPUC issued San Jose Water Company's most recent General
Rate Case decision  (D.04-08-054).  The decision  granted San Jose Water Company
authority to increase rates by $11,773,000 or 8.00% in 2004, $4,283,000 or 2.69%
in 2005 and $4,245,000 or 2.59% in 2006. The authorized  return on common equity
in 2004,  2005 and 2006 is 9.90%,  which is within the range of recent  rates of
return authorized by the CPUC for water utilities.

Pursuant to this general rate case decision, on  January 1, 2006, San Jose Water
Company  was  authorized  a revenue  increase  of  $4,245,000,  or about  2.59%,
designed to recover  projected  operating cost increases for 2006. Also pursuant
to  D.04-08-054,  on February 16, 2006 the CPUC  authorized an $863,000  revenue

                                       28

increase  to  recover  additional  plant  additions  originally   authorized  in
D.04-08-054. Finally, on March 3, 2006 the CPUC authorized the implementation of
a customer  surcharge to fund the repayment of a 20-year,  $2 million loan under
the Safe  Drinking  Water State  Revolving  Fund program  used to finance  water
quality improvements in the water system.

As required by Public  Utilities  Code Section  455.2,  on February 15, 2006 San
Jose  Water  Company  filed a General  Rate  Case  Application  requesting  rate
increases of  $14,646,000  or 8.54% in 2007,  $5,196,000  or 2.78% in 2008,  and
$6,246,000 or 3.26% in 2009. San Jose Water Company has also requested  recovery
of $451,000  from its various  balancing  and  memorandum  accounts via customer
surcharges.  San Jose Water Company is proposing this increase due to escalating
operating  expenses as well as significant  capital  expenditures  over the next
several years.

     Balancing Account Recovery Procedures
     -------------------------------------

On March 16, 2004,  the CPUC affirmed its June 19, 2003 decision  (D.03-06-072),
in  which  the  CPUC   revised  the   existing   procedures   for   recovery  of
under-collections  and  over-collections  in balancing  accounts  existing on or
after  November  29, 2001 as  follows:  (1) If a utility is within its rate case
cycle and is not  over-earning,  the utility shall recover its balancing account
subject  to  reasonableness  review;  and (2) If a utility  is either  within or
outside of its rate case cycle and is over-earning,  the  over-earnings  will be
used as a measure by which recovery of offset expenses in the balancing  account
will be reduced.  For example,  if the amount of the over-earning is equal to or
exceeds the amount of offset expenses to be recovered in the balancing  account,
those expenses shall be reduced to zero. Any offset expenses  accumulated in the
balancing  account would be amortized as other expenses and any offset  revenues
collected in the balancing  account would be returned to  ratepayers.  Utilities
shall use the recorded  rate of return  means test to evaluate  earnings for all
years.  The  expenses  used in this  earnings  test  shall be  adjusted  for any
"extraordinary"  expenses and revenue shall be adjusted for any  "extraordinary"
revenue.  The earnings test will use recorded rate base. Utilities must file for
recovery of the balancing account balances before March 31 of every year.

Subsequently,  on September 9, 2003 and March 30, 2004,  San Jose Water  Company
filed two compliance  filings  requesting  CPUC review of the balancing  account
over-collected balance of approximately  $382,000,  accrued between November 29,
2001 and December 31, 2003.  On June 15, 2004,  the CPUC notified San Jose Water
Company that the over-collected balances had been verified and should be carried
forward to the next review  period.  As of March 31, 2006 and December 31, 2005,
the  approved   balance  is  an   over-collection   of  $408,000  and  $403,000,
respectively, including interest on the approved amounts.

On March 30, 2005, San Jose Water Company filed a compliance  filing  requesting
the  CPUC  review  of  the   balancing   account   under-collected   balance  of
approximately  $999,000,  accrued between January 1, 2004 and December 31, 2004.
On June 24, 2005, San Jose Water Company filed a supplemental  compliance filing
revising the under-collected  balance to approximately  $760,000. On October 27,
2005, the CPUC notified San Jose Water Company that the under-collected  balance
had been verified and should be carried forward to the next review period. As of
March  31,  2006  and   December  31,   2005,   the   approved   balance  is  an
under-collection of $795,000 and $786,000,  respectively,  including interest on
the approved amounts.
                                       29

In March 2006 the CPUC's Executive Director granted all water utilities a 90-Day
Extension for  compliance  filings  requesting the CPUC's review of the balances
accrued in the Memorandum Type Balancing Account during 2005. This extension was
granted while the CPUC reconsidered the balancing account review process.  As of
March 31, 2006 and  December  31, 2005,  the total  accrued  balance in San Jose
Water  Company's  Memorandum  Type  Balancing  Account for the period  January 1
through  December 31, 2005,  was an  over-collection  of $141,000 and  $139,000,
respectively, including interest.

The  following is a summary of the  balancing  account and the  memorandum  type
balancing account:

ITEM 3.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
          ----------------------------------------------------------

SJW Corp. is subject to market risks in the normal course of business, including
changes in interest rates and equity prices. The exposure to changes in interest
rates is a result of financings  through the issuance of  fixed-rate,  long-term
debt and short-term funds obtained through the variable rate line of credit. SJW
Corp.  also owns  1,099,952  shares of  California  Water  Service  Group and is
exposed to the risk of changes in equity prices.

SJW Corp. has no derivative financial  instruments,  financial  instruments with
significant   off-balance   sheet   risks,   or   financial   instruments   with
concentrations  of credit risk.  There is no material  sensitivity  to change in
market rates and prices.


ITEM 4.   CONTROLS AND PROCEDURES
          -----------------------

     (a) SJW Corp.'s  management,  with the  participation  of SJW Corp.'s Chief
Executive  Officer and Chief Financial  Officer,  evaluated the effectiveness of
SJW  Corp.'s  disclosure  controls  and  procedures  as of the end of the period
covered by this report.  Based on that evaluation,  the Chief Executive  Officer

                                       30

and Chief Financial Officer concluded that SJW Corp.'s  disclosure  controls and
procedures (as defined in Rule 13(a)-15(e) under the Securities  Exchange Act of
1934) as of the end of the period  covered by this report have been designed and
are functioning effectively to provide reasonable assurance that the information
required to be  disclosed  by SJW Corp.  in reports  filed under the  Securities
Exchange Act of 1934 is recorded, processed,  summarized and reported within the
time periods  specified in the  Securities and Exchange  Commission's  rules and
forms. SJW Corp. believes that a control system, no matter how well designed and
operated,  cannot provide absolute  assurance that the objectives of the control
system are met, and no  evaluation  of controls can provide  absolute  assurance
that all control  issues and instances of fraud,  if any,  within a company have
been detected.

     (b) There has been no change in internal  control over financial  reporting
during the first  fiscal  quarter of 2006 that has  materially  affected,  or is
reasonably  likely to materially  affect the internal  controls  over  financial
reporting of SJW Corp.
