                          PART I. FINANCIAL INFORMATION
                     ATWOOD OCEANICS, INC. AND SUBSIDIARIES


     This Form 10-Q for the  quarterly  period  ended  March 31,  2005  includes
statements about Atwood Oceanics,  Inc. (which together with its subsidiaries is
identified  as the  "Company,"  "we"  or  "our,"  unless  the  context  requires
otherwise) which are not historical  facts (including any statements  concerning
plans  and   objectives  of  management   for  future   operations  or  economic
performance,   or  assumptions   related  thereto)  which  are   forward-looking
statements.  In addition,  we and our  representatives  may from to time to time
make other oral or written statements which are also forward-looking statements.

     These  forward-looking  statements are made based upon management's current
plans, expectations, estimates, assumptions and beliefs concerning future events
impacting  us and  therefore  involve a number of risks  and  uncertainties.  We
caution  that  forward-looking  statements  are not  guarantees  and that actual
results  could  differ  materially  from  those  expressed  or  implied  in  the
forward-looking statements.

     Important  factors that could cause our actual results of operations or our
actual financial  conditions to differ include,  but are not necessarily limited
to:

     - our dependence on the oil and gas industry;

     - the operational risks involved in drilling for oil and gas;

     - changes in rig utilization and dayrates in response to the level of
       activity in the oil and natural gas industry, which is significantly
       affected by indications and expectations regarding the level and
       volatility of oil and natural gas prices, which in turn are affected by
       such things as political, economic and weather conditions affecting or
       potentially affecting regional or worldwide demand for oil and natural
       gas, actions or anticipated actions by OPEC, inventory levels,
       deliverability constraints, and future market activity;

     - the extent to which customers and potential customers continue to pursue
       deepwater drilling;

     - exploration success or lack of exploration success by our customers and
       potential customers;

     - the highly competitive and cyclical nature of our business, with periods 
       of low demand and excess rig availability;

     - the impact of the war with Iraq or other military operations, terrorist 
       acts or embargoes elsewhere;

     - our ability to enter into and the terms of future drilling contracts;

     - the availability of qualified personnel;

     - our failure to retain the business of one or more significant customers;

     - the termination or renegotiation of contracts by customers;

                                      -3-



     - the availability of adequate insurance at a reasonable cost;

     - the occurrence of an uninsured loss;

     - the risks of international operations, including possible economic,
       political, social or monetary instability, and compliance with foreign
       laws;

     - the effect SARS or other public health concerns could have on our
       international operations and financial results;

     - compliance with or breach of environmental laws;

     - the incurrence of secured debt or additional unsecured indebtedness or 
       other obligations by us or our subsidiaries;

     - the adequacy of sources of liquidity;

     - currently unknown rig repair needs and/or additional opportunities to
       accelerate planned maintenance expenditures due to presently
       unanticipated rig downtime;

     - higher than anticipated accruals for performance-based compensation due
       to better than anticipated performance by us, higher than anticipated
       severance expenses due to unanticipated employee terminations, higher
       than anticipated legal and accounting fees due to unanticipated
       financing or other corporate transactions and other factors that could
       increase general and administrative expenses;

     - the actions of our competitors in the oil and gas drilling industry, 
       which could significantly influence rig dayrates and utilization;

     - changes in the geographic areas in which our customers plan to operate,
       which in turn could change our expected effective tax rate;

     - changes in oil and natural gas drilling technology or in our competitors'
       drilling rig fleets that could make our drilling rigs less competitive or
       require major capital investments to keep them competitive;

     - rig availability;

     - the effects and uncertainties of legal and administrative proceedings 
       and other contingencies;

     - the impact of governmental laws and regulations and the uncertainties 
       involved in their administration, particularly in some foreign 
       jurisdictions;

     - changes in accepted interpretations of accounting guidelines and other
       accounting pronouncements and tax laws; and

     - the risks involved in the construction and upgrade of our drilling units.



                                      -4-




     Undue reliance  should not be placed on these  forward-looking  statements,
which are applicable only on the date hereof. Neither we nor our representatives
have a general obligation to revise or update these  forward-looking  statements
to  reflect  events or  circumstances  that  arise  after the date  hereof or to
reflect the occurrence of unanticipated events.

                     ATWOOD OCEANICS, INC. AND SUBSIDIARIES
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


1.   UNAUDITED INTERIM INFORMATION
 
     The unaudited interim  condensed  consolidated  financial  statements as of
March 31, 2005 and for each of the three month  periods ended March 31, 2005 and
2004,  included  herein,  have  been  prepared  in  accordance  with  accounting
principles  generally  accepted  in the  United  States of America  for  interim
financial  information and with the instructions for Form 10-Q and Article 10 of
Regulation  S-X.  The year end  condensed  consolidated  balance  sheet data was
derived from the audited financial statements as of September 30, 2004. Although
these financial  statements and related  information  have been prepared without
audit,  and  certain  information  and note  disclosures  normally  included  in
financial statements prepared in accordance with accounting principles generally
accepted in the United  States of America  have been  condensed  or omitted,  we
believe  that the note  disclosures  are  adequate to make the  information  not
misleading.  The interim financial results may not be indicative of results that
could  be  expected  for a full  year.  It is  suggested  that  these  condensed
consolidated  financial  statements be read in conjunction with the consolidated
financial  statements  and the notes  thereto  included in our Annual  Report to
Shareholders  for the  year  ended  September  30,  2004.  In our  opinion,  the
unaudited interim financial  statements  reflect all adjustments  (consisting of
normal recurring  adjustments)  considered  necessary for a fair presentation of
our financial position and results of operations for the periods presented.


2.   SIGNIFICANT ACCOUNTING POLICIES

     Statement of Financial  Accounting  Standards ("SFAS") No. 123, "Accounting
for Stock-Based Compensation" allows companies the choice of either using a fair
value  method  of  accounting  for  options,   which  would  result  in  expense
recognition  for all options  granted,  or using an  intrinsic  value  method as
prescribed by Accounting  Principles  Board ("APB") Opinion No. 25,  "Accounting
for Stock Issued to Employees",  with pro forma  disclosure of the impact on net
income (loss) of using the fair value option expense recognition method.

     We apply the recognition  and measurement  principles of APB Opinion No. 25
and  related  interpretations.  Accordingly,  no  compensation  costs  have been
recognized  in net income  from the  granting  of options  pursuant to our stock
option plans,  as all options  granted  under those plans had an exercise  price
equal to the market value of the underlying common stock on the date of grant.

     Had compensation costs been determined based on the fair value at the grant
dates  consistent  with the method of SFAS No.  123,  our net income  (loss) and
earnings  (loss)  per share  would have been  reduced  to the pro forma  amounts
indicated below (in thousands, except for per share amounts):

     The fair value of grants made during the current fiscal year-to-date period
were estimated on the date of grant using the Black-Scholes option pricing model
with the  following  weighted-average  assumptions:  risk-free  interest  rate -
4.27%,  expected  volatility  - 35%,  expected  life - 6 years,  and no dividend
yield.

     In December 2004, the Financial  Accounting  Standards  Board (FASB) issued
SFAS No. 123 (Revised 2004), "Share-Based Payment" (SFAS 123(R)). This Statement
revises SFAS No. 123 by  eliminating  the option to account for  employee  stock
options under APB No. 25 and generally  requires companies to recognize the cost
of employee services received in exchange for awards of equity instruments based
on the grant-date  fair value of those awards (the  "fair-value-based"  method).
Originally,  SFAS No. 123R was to become effective for public entities as of the
beginning of the first interim reporting period that begins after June 15, 2005.
On April 14, 2005, the SEC announced it would permit companies to implement SFAS
123(R) at the  beginning  of their first  fiscal year  beginning  after June 15,
2005. Accordingly,  we plan to adopt SFAS 123(R) on October 1, 2006 and will use
the modified  prospective  method. The impact of adopting SFAS 123(R) will be to
record expense for previously-issued but unvested employee stock options and any
employee stock options that we issue in the future.  We expect the dollar impact
on  our  financial  statements  to be  consistent  with  the  impact  previously
disclosed  above in the pro  forma  disclosure  requirements  of SFAS  No.  123,
beginning with the first quarter of fiscal year 2006.

     Effective  October 1, 2004, we extended the remaining  depreciable  life of
the SEAHAWK from 2 months to 5 years,  due to a recent contract that extends the
rig's  commercial  viability  for up to 5 years.  We believe that this change in
depreciable life provides a better matching of the revenues and expenses of this
asset over its anticipated remaining useful life and will continue to depreciate
this rig on a straight-line  method for the remainder of the extended period. As
a  result  of  the  change  in  depreciable  life  from  2  months  to 5  years,
depreciation  expense was increased and net income was reduced by  approximately
$0.1  million,  or $.01 per share,  for the three month  period  ended March 31,
2005,  and  depreciation  expense was reduced  and net income was  increased  by
approximately  $0.8  million,  or $.05 per share for the six month  period ended
March 31,  2005.  Depreciation  expense  going  forward  will be higher  than it
otherwise  would have been because if not for this  extension  of the  SEAHAWK's
useful life,  this asset would have been fully  depreciated in the first quarter
of fiscal year 2005.


5.   COMMITMENTS AND CONTINGENCIES

     We are party to a number of lawsuits which are ordinary, routine litigation
incidental  to our  business,  the  outcome  of which,  individually,  or in the
aggregate,  is not expected to have a material  adverse  effect on our financial
position, results of operations, or cash flows.


                                      -13-



6.   CAPITAL STOCK

     In  October  2004,  we sold in a public  offering  1,175,000  shares of our
common  stock at an  effective  net price  (before  expenses)  of $45.83 for net
proceeds of approximately $53.6 million. We used these proceeds and cash on hand
to repay  the $55  million  outstanding  as of  September  30,  2004  under  the
revolving portion of our senior secured credit facility.


7.   ATWOOD BEACON

     The ATWOOD BEACON  incurred  damage to all three legs and the derrick while
positioning  for a well  offshore  of  Indonesia  in July 2004.  The rig and its
damaged  legs were  transported  to the  builder's  shipyard  in  Singapore  for
inspections  and repairs.  At September  30, 2004,  the book basis of the ATWOOD
BEACON was reduced by $16.3 million  which was the estimated  reduction in value
caused by the  incident.  An insurance  receivable  totaling  $25.4  million was
recorded for such  estimated  damage,  as well as estimated  recovery  costs and
business interruption loss incurred through September 30, 2004.

     During the first half of fiscal year 2005,  approximately  $15.8 million of
capitalized costs were incurred to restore the rig to its condition prior to the
incident of which $8.4 million has been  reimbursed by the insurance  carrier as
of March 31,  2005.  In  addition,  we also  collected  $6.4 million of business
interruption proceeds during the current fiscal year and $7.5 million related to
recovery and  transportation  costs.  We expect to collect the  remaining  $11.1
million insurance receivable during fiscal year 2005.



8.   INCOME TAXES

     Virtually  all of our tax  provision  for each of the three  months and six
months ended March 31, 2005 and 2004 relates to taxes in foreign  jurisdictions.
Accordingly,  due to the high level of  operating  losses in certain  nontaxable
jurisdictions  during  the three  and six  months  ended  March  31,  2004,  our
effective  tax rate for fiscal year 2004  periods  exceeded  the U.S.  statutory
rate.

     In December 2004, we received a $1.7 million tax refund in Malaysia related
to a previously reserved tax receivable. In addition, we earned revenue from our
loss of hire insurance  coverage on the ATWOOD BEACON in a zero tax jurisdiction
during the three and six months ended March 31, 2005.  Our  operating  losses in
certain nontaxable jurisdictions during the three and six months ended March 31,
2005 are significantly less as compared to the same periods in fiscal year 2004.
As a result,  our  effective  tax rate for the current  fiscal year periods were
significantly less than the U.S. statutory rate.

                     ATWOOD OCEANICS, INC. AND SUBSIDIARIES
                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITIONS AND RESULTS OF OPERATIONS


     All non-historical  information set forth herein is based upon expectations
and assumptions we deem reasonable by the Company. We can give no assurance that
such  expectations and assumptions will prove to be correct,  and actual results
could differ  materially from the  information  presented  herein.  Our periodic
reports filed with the SEC should be consulted for a description of risk factors
associated with an investment in us.

MARKET OUTLOOK AND FINANICIAL CONDITION

     Current  worldwide  utilization of offshore drilling units is approximately
88% compared to approximately 82% in April 2004. Recent contract awards for some
of our drilling  units reflect the highest  dayrate levels that these units have
ever  received.  We  continue to  experience  high bid  activity  levels for our
drilling  units.  We believe  that our eight key  drilling  units  (seven  units
upgraded since 1996 and one newly constructed unit which commenced  operation in
August  2003)  are  well  placed  to  take  advantage  of  strengthening  market
conditions.

     During the quarter ended March 31, 2005, the ATWOOD  SOUTHERN CROSS and the
SEAHAWK incurred 12 days and 27 days, respectively, of idle time, with our other
six drilling units being 100% utilized.  The ATWOOD  SOUTHERN CROSS is currently
working in Myanmar  under a contract  which should be completed in May 2005.  It
will then be  relocated  to the  Mediterranean  Sea to work for three  different
customers,  which is expected to take around six months to complete. The SEAHAWK
will be idle until  early May 2005 when it returns  to work  offshore  Malaysia.
Upon the SEAHAWK  returning to work, we expect to have all of our eight drilling
units almost fully  booked for the  remainder of fiscal year 2005.  We currently
have  approximately 50% of available rig days in fiscal year 2006  contractually
committed.

     We remain  optimistic  about the long-term  outlook and fundamentals of the
offshore  drilling  market.  Compared to fiscal year 2004, we expect fiscal year
2005 will  reflect  increasing  earnings  and cash  flows.  Based  upon  current
contract  commitments,  we expect high utilization of our drilling units through
fiscal year 2006.  For fiscal year 2006,  the ATWOOD  EAGLE,  ATWOOD  HUNTER and
SEAHAWK have contractually committed dayrates of $170,000,  $125,000 and $68,430
respectively, which will be the highest dayrates these units have ever received.
With an improved market environment, current capital ratio to total debt of 25%,
current annual capital commitments for maintenance of our eight active drillings
units expected to only be $6 to $10 million and expected high utilization of our
drilling  units during the  remainder of fiscal year 2005 and all of fiscal year
2006,  we  anticipate  that our balance  sheet and  liquidity  will  continue to
strengthen.

     The increase in revenue for the ATWOOD EAGLE for the current quarter is due
to 100%  utilization  compared  to only 25%  utilization  plus  amortization  of
mobilization revenues of approximately $900,000 in the prior fiscal year quarter
as the rig was being  relocated  from West Africa to  Australia.  Along with the
current  quarter  difference,  year-to-date  revenues are higher compared to the
prior  year-to-date  period as the rig was only 70%  utilized  during  the first
quarter of the prior  fiscal year  compared to full  utilization  in the current
quarter.  The average dayrates for the ATWOOD BEACON were approximately  $65,000
and $68,000,  which included 18 and 110 days of loss of hire insurance,  for the
three and six months  ended March 31,  2005,  respectively,  compared to average
dayrates of approximately $52,000 and $50,000 for the three and six months ended
March 31, 2004.  The increase in revenue for the ATWOOD  SOUTHERN  CROSS for the
current quarter is due to approximately  90% utilization at a dayrate of $35,000
compared to  approximately  35%  utilization at dayrates  ranging from $30,000 -
35,000 plus amortization of mobilization  revenues of approximately  $700,000 in
the prior  fiscal  year  quarter  as the rig was being  relocated  from India to
Malaysia. The average dayrate for the RICHMOND was approximately $30,000 for the
three and six months  ended March 31,  2005,  compared to an average  dayrate of
approximately  $25,000  for the  three and six  months  ended  March  31,  2004.
Revenues for the VICKSBURG for the current quarter and year-to-date  period were
consistent for the same periods in the prior fiscal year,  while the decrease in
revenue for the ATWOOD  HUNTER for the  quarter  ended March 31, 2005 was due to
approximately one week of downtime for repairs and maintenance  compared to full
utilization  for the quarter  ended March 31, 2004.  However,  the  year-to-date
increase  is due to  approximately  95%  utilization  at a  dayrate  of  $62,000
compared to  approximately  90%  utilization at dayrates  ranging from $40,000 -
$62,000  for the prior  fiscal  year-to-date  period.  Revenue  for the  SEAHAWK
decreased due to 70%  utilization  during the current  quarter  compared to 100%
utilization  during  the same  period  in fiscal  year  2004.  The  year-to-date
decrease also includes three months  amortization of deferred upgrade revenue of
approximately  $1.3  million  during the first  quarter of the prior fiscal year
compared to no amortization of such revenue during the first quarter of the

                                      -16-




current fiscal year as  amortization of the upgrade revenue ended November 2003.
The average  dayrate  for the ATWOOD  FALCON was  approximately  $68,000 for the
current quarter compared to an average dayrate of approximately  $83,000 for the
prior fiscal year quarter,  while year-to-date  revenues are consistent with the
prior fiscal year period.

     Contract  drilling  costs for the three and six months ended March 31, 2005
increased  10% and 11%,  respectively,  as  compared to the three and six months

     The  increase in  drilling  costs for the ATWOOD  EAGLE  during the current
quarter is due to a full quarter of operating costs compared to approximately 30
days of operating  costs along with  amortization  of  mobilization  expenses of
approximately  $900,000 in the prior  fiscal  year  quarter as the rig was being
relocated from West Africa to Australia. The year-to-date increase also includes
an  approximate  $20,000 per day higher salary  expense  attributable  to higher
Australian  labor  costs and  additional  rig  personnel  required  due to local
operating  requirements in Australia during the quarter ended December 31, 2004,
compared to operating  in West Africa where labor costs are lower,  its location
in the first  quarter of the prior fiscal year.  The increase in drilling  costs
for the SEAHAWK were due to higher repair and maintenance  expenses  incurred on
the rig during the three and six months  ended  March 31,  2005  compared to the
three and six months  ended March 31,  2004.  Drilling  costs for the  RICHMOND,
ATWOOD  HUNTER and VICKSBURG  remained  consistent  for the current  quarter and
year-to-date period as compared to the same periods in the prior fiscal year. In
addition,  the current quarter  drilling costs for the ATWOOD SOUTHERN CROSS are
also  comparable to the prior fiscal year  quarter.  However,  the  year-to-date
drilling  costs have  decreased  when compared to the prior fiscal  year-to-date
period  due to the fact the rig  incurred  approximately  $1.6  million  of boat
towing  costs while  relocating  from Egypt to India  during the  quarter  ended
December 31, 2003  compared to no such costs in the quarter  ended  December 31,
2004.  Despite being under repair during the current  fiscal year until January,
the ATWOOD BEACON incurred labor,  insurance,  supplies and other drilling costs
during that period and thus, current quarter and year-to-date drilling costs are
relatively  consistent  with the prior  fiscal  year  periods.  Current  quarter
drilling  costs for the ATWOOD  FALCON have  decreased  as the prior fiscal year
quarter included amortization of mobilization expenses of $1.4 million resulting
from the rig's relocation from Malaysia to Japan while year-to-date revenues are
consistent  with the  prior  fiscal  year  period.  Other  drilling  costs  have

                                      -17-


increased  for the three and six months ended March 31, 2005 as the prior fiscal
year quarter includes the settlement of a dispute with a customer which resulted
in a  reduction  to  drilling  costs of  approximately  $600,000  and the  prior
year-to-date period includes an insurance premium refund of $500,000.

ended March 31, 2005  compared to the three and six months  ended March 31, 2005

     Effective  October 1, 2004, we extended the remaining  depreciable  life of
the SEAHAWK from 2 months to 5 years,  as discussed in Note 4, which resulted in
a current  quarter and  year-to-date  reduction  of  depreciation  expense.  The
depreciable  life of this rig was  extended  based upon a recent  contract  that
extends  the rig's  commercial  viability  for up to 5 years,  coupled  with our
intent to continue marketing and operating the rig beyond 2 months.

LIQUIDITY AND CAPITAL RESOURCES
 
 
     Due to the cyclical nature of the offshore drilling  industry,  maintaining
high equipment  utilization of our eight active drilling units in up, as well as
down,  cycles is a key factor in generating  cash to satisfy  current and future
obligations.  Since fiscal year 2000, net cash provided by operating  activities
ranged from a low of approximately  $14 million in fiscal year 2003 to a high of
approximately  $62  million  in fiscal  year  2001,  with net cash  provided  by
operating  activities in fiscal year 2004 of approximately $26 million. Net cash
provided  by  operating  activities  for the first half of fiscal  year 2005 was
approximately  $26.9  million.  We expect  that in fiscal  year  2005,  net cash
provided by operating  activities will be  approximately  $50 to $55 million for
the full fiscal year period.  Our operating  cash flows are primarily  driven by
our operating  income,  which  reflects  dayrate and rig  utilization.  Assuming
higher dayrates and strengthening market conditions,  we should have higher cash
flows and earnings in fiscal year 2005 compared to fiscal year 2004.  Currently,
our existing cash  commitments for the remainder of fiscal year 2005 and beyond,
outside of funding current rig operations,  includes annual capital expenditures
of $6 to $10 million  for  maintenance  of our eight  active  drilling  rigs and
quarterly  repayments of $9 million under the term portion of our senior secured
credit facility.  We expect to generate sufficient cash flows from operations to
satisfy these obligations.

     At March 31, 2005, we had $108 million  outstanding  under the term portion
and $5 million  outstanding  under the revolving  portion of our senior  secured
credit  facility.  In October 2004, upon concluding our 1,175,000  common shares
stock offering,  we repaid the $55 million then outstanding  under the revolving
portion of our senior  secured  credit  facility with proceeds from the offering
and cash on hand.  We  currently  have  approximately  $94 million of  available
borrowing  capacity  and with a debt to  total  capitalization  ratio  currently
around  25%,  we expect to remain in  compliance  with all  financial  covenants
during the remainder of fiscal year 2005.  The collateral for our senior secured
credit facility  consists  primarily of preferred  mortgages on all eight of our
active  drilling  units  (with an  aggregate  net book  value at March 31,  2005
totaling  approximately  $391  million).  We  are  required  to  pay  a  fee  of
approximately  .80% per  annum  on the  unused  portion  of the  revolving  loan
facility and certain other administrative costs.

     The SEASCOUT,  a  semisubmersible  hull planned for future  conversion  and
upgrade to a semisubmersible tender assist vessel, continues to be cold-stacked.
We expect that the cost to convert and upgrade the SEASCOUT could range from $70
million to $80 million.  We have no current capital commitments on the SEASCOUT,
as we do not expect to undertake a conversion  and upgrade  until an  acceptable
contract  opportunity  has been secured and adequate  financing is in place.  We
continue to periodically  increase and adjust our planned  capital  expenditures
and financing of such expenditures in light of current market conditions.

     Our portfolio of accounts  receivable  is comprised of major  international
corporate  entities with stable payment  experience.  Historically,  we have not
encountered  significant  difficulty in collecting  receivables and typically do
not require  collateral for our receivables.  The insurance  receivable of $25.4
million at  September  30, 2004 and $11.1  million at March 31, 2005  related to
repairs  made to the ATWOOD  BEACON.  We expect to encounter  no  difficulty  in
collecting  the remaining  $11.1 million due from the repairs made to the ATWOOD
BEACON.

                     ATWOOD OCEANICS, INC. AND SUBSIDIARIES
           QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     We are exposed to market risk,  including  adverse change in interest rates
and foreign currency exchange rates as discussed below.

INTEREST RATE RISK

     With the  interest  rate on our  long-term  debt under our  current  credit
facilities at a floating rate, the outstanding long-term debt of $113 million at
March 31, 2005  approximates its fair value. The impact on annual cash flow of a
10%  change  in the  floating  rate  (approximately  55 basis  points)  would be
approximately $0.6 million,  which we do not believe to be material.  We did not
have any open derivative  contracts  relating to our floating rate debt at March
31, 2005.

FOREIGN CURRENCY RISK

     Certain of our  subsidiaries  have monetary assets and liabilities that are
denominated in a currency other than their functional currencies. Based on March
31,  2005  amounts,  a decrease  in the value of 10% in the  foreign  currencies
relative to the U.S.  dollar from the year-end  exchange rates would result in a
foreign currency transaction loss of approximately $0.6 million, which we do not
believe to be material.  We did not have any open derivative  contracts relating
to foreign currencies at March 31, 2005.

                             CONTROLS AND PROCEDURES


(a)      Evaluation of Disclosure Controls and Procedures

         Our management, with the participation of our Chief Executive Officer 
         and Chief Financial Officer, evaluated the effectiveness of our 
         disclosure controls and procedures as of the end of the period covered 
         by this report.  Based on that evaluation, the Chief Executive Officer 
         and Chief Financial Officer concluded that our disclosure controls and 
         procedures 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 us in our 
         periodic SEC filings is recorded, process, summarized and reported 
         within the time periods specified in the SEC's rules, regulations and 
         forms.  We believe that a controls system, no matter how well designed 
         and operated, cannot provide absolute assurance that the objectives of 
         the controls 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)      Changes in Internal Control over Financial Reporting

         No change in our internal control over financial reporting occurred 
         during the fiscal quarter covered by this report that has materially 
         affected, or is reasonably likely to materially affect, our internal 
         control over financial reporting.

                 registrant's fourth fiscal quarter in the case of an annual
                 report) that has materially affected, or is reasonably likely
                 to materially affect, the registrant's internal control over 
                 financial reporting; and

                                      -26-
