      This Amendment No. 1 on Form 10-Q/A (this "Amendment") to the
      Quarterly Report on Form 10-Q of Bio-Rad Laboratories, Inc.
      (the "Company") for the six months ended June 30, 2004 (the "Form 10-Q")
      is being filed to amend Item 1 (Financial Statements) of the Form 10-Q
      solely to correct one typographical error in the consolidated statements
      of cash flows. The revised financial statements replace the figure "--"
      with the figure "(5,957)" in the line item "Payments for acquisitions and
      investments" for the six months ended June 30, 2003. No other changes to
      the original Form 10-Q filed on August 8, 2004 have been made. This
      Amendment also does not reflect any events that have occurred after the
      original filing date of the Form 10-Q.  For ease of reference, this
      Amendment restates the Form 10-Q in its entirety.

      4.   GOODWILL AND INTANGIBLES

      The Company adopted Statement of Financial Accounting Standards
      ("SFAS") No. 142, "Goodwill and Other Intangible Assets" as of
      January 1, 2002, which provides that goodwill is no longer subject
      to amortization over its useful life.  Goodwill is subject to an
      annual assessment for impairment applying a fair-value based test.

      As part of the acquisition of the controls business of Hematronix
      in March 2004, (see Note 5) the Company added $3.2 million of
      Goodwill and $9.3 million of intangible assets including in-
      process research and development.  Other than in-process research
      and development, these intangible assets will be amortized over 5-
      7.5 years at an estimated annual amount of $1.3 million.

      In June 2004, the Company purchased $14.0 million of intangible
      assets related to licensing agreements. The Company paid $6.0
      million upon acquisition and will pay the remaining $8.0 million
      over the next two years.  These intangible assets will be
      amortized over 15.5 years at an estimated annual amount of $0.9
      million.

      5.   ACQUISITIONS AND INVESTMENTS

      In March 2004, the Company purchased for cash the controls
      business of Hematronix, Inc. of Plano, Texas.  Bio-Rad acquired
      tangible and intangible assets and assumed certain liabilities for
      approximately $17 million.  Acquired in-process research and
      development of $0.9 million was charged to expense in the first
      quarter.

      During the first six months of 2004, the Company invested an
      additional $10.9 million in Sartorius AG ("Sartorius"), of
      Goettingen, Germany, a process technology supplier to the
      biotechnology, pharmaceutical, chemical and food and beverage
      industries.  At June 30, 2004, the Company owned approximately 21%
      of the outstanding voting shares of Sartorius.  The Sartorius
      family trust and Sartorius family members hold approximately 60%
      of the outstanding voting shares.  Bio-Rad does not have any
      representative or designee on Sartorius' board of directors,
      nor does it have any other influence over the operating and
      financial policies of Sartorius.  Therefore, the Company accounts
      for this investment using the cost method.

      In June 2004, the Company signed a letter of intent to acquire MJ
      GeneWorks, Inc. and its subsidiaries.  MJ GeneWorks is the parent
      company of MJ Research, Inc. of Waltham, Massachusetts, a
      biotechnology company specializing in thermal cycling
      instrumentation and reagents used to amplify DNA.  Under the
      proposed agreement, Bio-Rad will acquire tangible and intangible
      assets for approximately $47 million in cash and assume certain
      liabilities.  The acquisition is subject to completion of a
      definitive purchase agreement which has not been completed as of the
      date of this filing.

                                       5
      


      6.   DISCONTINUED OPERATIONS

      On May 31, 2004, the Company sold a group of assets and transferred
      certain liabilities that comprise a substantial portion of the
      Company's confocal microscopy product line to Carl Zeiss Jena GMBH.
      Proceeds received were $19.8 million and costs included net assets
      of $5.7 million, lease settlements of $6.7 million and severance,
      legal and other costs of $1.7 million resulting in a pre-tax gain of
      $5.7 million.  Payments on the lease liability will continue until
      2008.  All other costs should be settled by December 31, 2004.

      As required by SFAS 144, "Accounting for the Impairment or Disposal
      of Long-Lived Assets," with the disposition of this asset group, the
      sales and expenses related to this product line for current and
      prior periods results have been reclassified as a separate line on
      the income statement titled "Discontinued Operations."

      The discontinued operations generated net sales of $2.4 million and
      $4.2 million for the three months ended June 30, 2004, and 2003.
      Net sales for the six months ended June 30, 2004 and 2003 were $6.3
      million and $9.8 million, respectively.  The pre-tax operating
      losses attributable to the discontinued operations for the three
      months ended for June 30, 2004 and 2003 were $1.2 million and $1.5
      million, respectively.  The pre-tax operating losses attributable to
      the discontinued operations for the six months ended June 30, 2004
      and 2003 were $2.0 million and $2.1 million, respectively.

      7.   PRODUCT WARRANTY LIABILITY

      The Company warrants certain equipment against defects in design,
      materials and workmanship, generally for one year.  Upon shipment
      of that equipment, the Company establishes, as part of cost of
      goods sold, a provision for the expected cost of such warranty.

      Components of the product warranty liability included in Other
      current liabilities and Other long-term liabilities, were as
      follows (in millions):

                                             2004        2003

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

      8.   LONG-TERM DEBT

      In August 2003, the Company sold $225.0 million principal amount
      of Senior Subordinated Notes due 2013.  The notes pay a fixed rate
      of interest of 7.5% per year.  During 2003, the Company also
      negotiated a new five-year $150 million revolving credit facility.
      Interest on the facility varies based upon a number of factors
      including the duration of the specific borrowing and is based upon


                                       6
      


      either the Eurodollar, the Federal Funds effective or the Company
      corporate-based rate.

      9.   EARNINGS PER SHARE

      The Company calculates basic earnings per share (EPS) and diluted
      EPS in accordance with SFAS No. 128, "Earnings per Share."  Basic
      EPS is computed by dividing net income (loss) by the weighted
      average number of common shares outstanding for that period.
      Diluted EPS takes into account the effect of dilutive instruments,
      such as stock options, and uses the average share price for the
      period in determining the number of common stock equivalents that
      are to be added to the weighted average number of shares
      outstanding.  Common stock equivalents are excluded from the
      diluted earnings per share calculation if the effect would be anti-
      dilutive.

      Weighted average shares used for diluted earnings per share
      include the dilutive effect of outstanding stock options to
      purchase 805,000 and 955,000 shares for the three months ended
      June 30, 2004 and 2003, respectively.  Options to purchase 5,000
      shares of common stock were outstanding during the three month
      period ended June 30, 2004, but were excluded from the computation
      of diluted earnings per share because the exercise price of the
      options was greater than the average market price of the common
      shares.  There were no anti-dilutive options for the three months
      ended June 30, 2003.

      Weighted average shares used for diluted earnings per share
      include the dilutive effect of outstanding stock options to
      purchase 812,000 and 878,000 shares for the six months ended June
      30, 2004 and 2003, respectively.  There were 4,000 anti-dilutive
      options for the six months ended June 30, 2004.  There were no anti-
      dilutive options for the six months ended June 30, 2003.

      10.  STOCK OPTIONS AND PURCHASE PLANS

      Stock Option Plans
      ------------------

      The Company maintains incentive and non-qualified stock option
      plans for officers and certain other key employees.  Under the
      2003 Stock Option Plan, options to purchase 306,990 shares were
      granted during the six months ended June 30, 2004.  Under the 1994
      Stock Option Plan, options to purchase 302,993 shares were granted
      during the six months ended June 30, 2003.  No options have been
      issued to non-employees.

      The Company applies the recognition and measurement principles of
      APB Opinion No. 25, "Accounting for Stock Issued to Employees,"
      and related interpretations in accounting for those plans.  No
      stock-based employee compensation expense is reflected in net
      income as all options granted under those plans had an exercise
      price equal to or greater than the market value of the underlying
      common stock on the date of grant.

      Had compensation cost for the Company's stock option and stock
      purchase plans been accounted for under SFAS No. 123, "Accounting
      for Stock-Based Compensation," the Company's pro forma net income
      and earnings per share would have been as follows (in millions,

      For purposes of the pro forma disclosures, the estimated fair value
      of the options granted is amortized to expense over the options'
      vesting period. There were no options granted during the three month
      periods ended June 30, 2004 and 2003.  The fair value of options
      granted was estimated using the Black-Scholes model with the
      following weighted average assumptions:

                                             Six Months
                                            Ended June 30,

      Expected dividend                      --        --

      The weighted average fair value of employee stock options granted
      during the six months ended June 30, 2004 and 2003 was $18.74 and
      $11.85, respectively.

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

      The Company has an employee stock purchase plan that provides that
      eligible employees may contribute up to 10% of their compensation up
      to $25,000 annually toward the quarterly purchase of shares of the
      Company's Class A common stock.  The employees' purchase price is
      85% of the lesser of the fair market value of the stock on the first
      business day or the last business day of each calendar quarter.  No

                                       8
      

      compensation expense is recorded in connection with the plan.  The
      Company has authorized the sale of 1,890,000 shares of common stock
      under the plan.

      The Company sold 14,729 shares for $0.7 million and 17,257 shares
      for $0.5 million under the plan to employees for the three months
      ended June 30, 2004 and 2003, respectively.  The Company sold 32,002
      shares for $1.5 million and 35,898 shares for $1.1 million under the
      plan to employees for the six months ended June 30, 2004 and 2003,
      respectively.  At June 30, 2004, 237,237 shares remain authorized
      under the plan.

      The fair value of the employees' purchase rights was estimated using
      the Black-Scholes model with the following assumptions:

                                            Three Months          Six Months
                                            Ended June 30,      Ended June 30,

                                          ------    ------    ------    ------
      Expected volatility                 19.55%    51.91%    20.02%    45.22%

      Expected dividend                      --        --        --        --

      The weighted average fair value of those purchase rights granted
      during the three months ended June 30, 2004 and 2003 was $10.69 and
      $8.73, respectively.  The weighted average fair value of those
      purchase rights granted during the six months ended June 30, 2004
      and 2003 was $10.89 and $8.39, respectively.

      Segment results are presented in the same manner as the Company
      presents its operations internally to make operating decisions and
      assess performance.  Net corporate operating income (expense) consists
      of receipts and expenditures that are not the primary responsibility
      of segment operating management.

      Interest expense is charged to segments based on the carrying amount
      of inventory and receivables employed by that segment.  The following

      15.  LEGAL PROCEEDINGS

      The Company is party to various claims, legal actions and complaints
      arising in the ordinary course of business.  The Company does not
      believe that any ultimate liability resulting from any of these
      lawsuits will have a material adverse effect on its results of
      operations, financial position or liquidity.  However, the Company
      cannot give any assurance regarding the ultimate outcome of these
      lawsuits and their resolution could be material to the Company's
      operating results for any particular period, depending upon the level
      of income for the period.

      Item 2.   Management's  Discussion and Analysis of
                Results of Operations and Financial Condition.

      This discussion should be read in conjunction with the information
      contained in both the Company's Consolidated Financial Statements
      for the year ended December 31, 2003 and this report for the quarter
      ended June 30, 2004.

      Other than statements of historical fact, statements made in this
      report include forward looking statements, such as statements with
      respect to the Company's future financial performance, operating
      results, plans and objectives that involve risk and uncertainties.
      We have based these forward looking statements on our current
      expectations and projections about future events.  However, actual
      results may differ materially from those currently anticipated
      depending on a variety of risk factors including among other things:
      our ability to successfully develop and market new products; our
      reliance on and access to necessary intellectual property; our
      ability to service our debt; competition in and government

                                       11
      

      regulation of the industries in which we operate; and the monetary
      policies of various countries.  We undertake no obligation to
      publicly update or revise any forward looking statements, whether as
      a result of new information, future events, or otherwise.

      Overview.  We are a multinational manufacturer and worldwide
      distributor of Life Science research and Clinical Diagnostics
      products.  Our business is organized into two primary segments, Life
      Science and Clinical Diagnostics, with the mission to provide
      scientists with specialized tools needed for biological research and
      clinical diagnostics.  We sell more than 8,000 products and services
      to a diverse client base comprised of scientific research,
      healthcare, industry, education and government customers worldwide.
      We manufacture and supply our customers with a range of reagents,
      apparatus and equipment to separate complex chemical and biological
      materials and to identify, analyze and purify components.  Because
      our customers require replication of results from experiments and
      tests, we estimate that approximately 70% of our revenues are
      recurring.  Approximately 36% of our second quarter 2004
      consolidated net sales are from the United States and approximately
      64% are international sales largely denominated in local currency
      with the majority of these sales in Euros, Yen and British Sterling.
      As a result, our consolidated sales expressed in dollars benefit
      when the US dollar weakens and suffers when the dollar strengthens
      in relation to other currencies.  Currency fluctuations benefited
      our consolidated sales expressed in US dollars in the current
      quarter ended June 30, 2004 as well as the prior period.

      On a currency neutral basis, the diagnostic market is growing around
      3% comprised of specialty areas experiencing significant growth
      offset by flat to declining growth in the routine testing market.
      Pricing for routine diagnostic tests is impacted by declining
      reimbursement schedules particularly in the US, Japan and Germany.

      The ambient growth of the life science market is currently about 5%
      on a currency neutral basis.  Some spending on government sponsored
      research has slowed or is being deferred especially in the US and
      Japan.  Large capital instrumentation systems continue to lag the
      ambient growth rate while reagents are rising faster than that
      average.  The market for BSE tests continues to be very dynamic as
      established countries consolidate testing resulting in competitive
      pricing pressures and lower selling prices. We anticipate that
      growth in BSE testing will come from the opening of new testing
      markets.

      Science segment sales grew 3.4%.  On a currency neutral basis,
      Clinical Diagnostics sales growth was 8.8%, while Life Science sales
      declined 1.3%.  Clinical Diagnostics sales were driven by its
      quality control product line and to a lesser extent its diabetes and
      blood virus products.  While quality control products did benefit
      from the recent Hematronix acquisition, greater than half of its
      growth came from existing products.   Life Science sales experienced
      growth in its multiplex protein array technology, amplification
      reagents, and electrophoresis product lines.  Sales declined for the
      food science products as average selling prices declined in the very

                                       13
      

      competitive BSE market, but at a slower rate.  The Company was
      recently awarded contracts to provide tests to the US market for
      enhanced surveillance testing.

      Consolidated gross margins were 57.4% for the second quarter of 2004
      compared to 56.4% for the second quarter of 2003 and 56.8% for all
      of 2003.  Both Life Science and Clinical Diagnostics gross margins
      increased when compared to the second quarter of 2003.  Life Science
      margin improvements are attributable to product sales mix and lower
      customer support costs on the segment's BSE product line.  Clinical
      Diagnostics margins improvements are attributable to product sales
      mix and, to a lesser extent, lower compliance costs and the
      selective termination of some older products.

      Selling, general and administrative expenses (SG&A) represented
      34.6% of sales for the second quarter of 2004 compared to 32.2% of
      sales for the second quarter of 2003.  The Company experienced
      significant growth in the rate of spending for advertising,
      facilities and professional services for information technology,
      legal and financial services associated with intellectual property
      rights and government compliance.

      Product research and development expense increased 16.1% to $25.5
      million in the second quarter of 2004 compared to the prior quarter.
      Both Life Science and Clinical Diagnostics increased their research
      and development expenditures in absolute dollars.  Areas of
      development for the Life Science segment are proteomics, process
      chromatography, and food safety.  Diagnostic development efforts are
      focused on expanded tests for its recently announced Bioplex 2200
      testing platform, molecular diagnostic tests and expanded software
      data management product offerings for its quality control product
      line.

      Corporate Results - Other Items

      Interest expense increased from the prior year by 33%.  The increase
      is the net effect of the Company increasing its average indebtedness
      from $112.1 million at June 30, 2003 to $236.0 million at June 30,
      2004.  The Company refinanced all of its debt in the second half of
      2003, increasing the amount borrowed with more favorable terms,
      which included a longer term to maturity and a lower interest rate.

      Exchange gains and losses consist of foreign currency transaction
      gains and losses and the premiums and discounts on forward foreign
      exchange contracts used to manage our foreign exchange risk where
      the cost of economic hedging is prohibitive or a cost effective
      market does not exist.

      Other income and expense for the second quarter of 2004 and 2003
      consists of investment and interest income.  Also included in other
      income and expense are gains or losses associated with the sale of
      any surplus manufacturing equipment or other productive assets.

      The Company's effective tax rate was 31% and 33% for the second
      quarter of 2004 and 2003 respectively.  The current period benefits
      from a rate decline from tax planning opportunities resulting from
      increased foreign profitability.

        In May, the Company sold its U.K. based confocal microscopy
      product line to Carl Zeiss Jena GMBH.  As required by SFAS 144, the
      sales and expenses related to this product line for current and
      prior periods have been reclassified to a separate line on the
      income statement titled "Discontinued Operations." The gain on
      divestiture was $3.4 million, net of tax.  Proceeds received were
      $19.8 million and costs included assets transferred less related
      liabilities, legal costs, a provision for leased facilities through
      August 2008 and minor severance and other costs. See Note 6.

      Corporate Results -- Sales, Margins and Expenses

      Net sales (sales) in the first half of 2004 rose 9.1% to $523.3
      million from $479.7 million in the first half of 2003. The positive
      impact to sales from a weakening US dollar represented $33.3
      million. For the Company in total, on a currency neutral basis,
      sales grew 2.1% compared to the prior year period.  Before
      adjustment to a currency neutral basis, the Clinical Diagnostics
      segment sales grew by 11.8% to $283.3 million and the Life Science
      segment sales grew 6.1% to $235.5 million.  On a currency neutral
      basis, the Clinical Diagnostics segment's sales increased 4.9% and
      the Life Science segment's sales declined 1.0%.  The Clinical
      Diagnostic sales increase is principally due to its quality control,
      autoimmune testing and diabetes monitoring products.  Life Science
      sales growth is attributable to multiplex protein array technology,
      amplification reagents, and electrophoresis product lines.  Life
      Science sales declined for food science products as the Company's
      BSE test faces competitive pricing pressure.  Each segment benefited
      by approximately 6.9% as a result of a weakening US dollar improving
      their international sales.

      Consolidated gross margins were 57.1% for the first half of 2004
      compared to 57.5% for the first half of 2003 and 56.8% for all of
      2003.  Life Science gross margins excluding the BSE product line
      remained unchanged from the prior year.  The gross margin for the
      BSE product line has declined, affecting the Life Science segment
      due to lower overall average prices in a consolidating and
      competitive market.  Diagnostic margins improved on sales mix as
      higher margin product lines represented a large percentage of the
      total sales mix.

      Selling, general and administrative expenses (SG&A) represented
      33.9% of sales for the first half of 2004 compared to 31.7% of sales
      in the prior year period.  The Company had planned growth in the

                                       15
      

      rate of spending for advertising, personnel, facilities and
      professional services for information technology improvements, legal
      and financial services in connection with intellectual property
      rights and compliance.

      Product research and development expense increased 17.1% to $49.9
      million in the first half of 2004 compared to the same period in
      2003 excluding $0.9 million of expense for acquired in-process
      research and development in the first quarter of 2004 associated
      with the Company's acquisition of Hematronix. Both Life Science and
      Clinical Diagnostics increased their research and development
      expenditures in absolute dollars.  Areas of development for Life
      Science are proteomics, process chromatography and food safety.
      Clinical Diagnostics development efforts were focused on completion
      and regulatory approval of the recently announced BioplexTM 2200
      platform and diagnostic test panels for it and expanded data
      management software products for the quality control product line.

      Corporate Results - Other Items

      Interest expense for the first half of 2004 increased from the same
      period in the prior year by 19.4%.  This increase is the net effect
      of the Company increasing its average indebtedness from $112.1
      million in the first half of 2003 to $236.0 million for the first
      half of 2004. During the second half of 2003, the Company refinanced
      all of its debt and increased the amount borrowed, represented
      largely by its 11-5/8% bonds, and replaced it with new 7.5% bonds.

      Exchange gains and losses consist of foreign currency transaction
      gains and losses and the premiums and discounts on forward foreign
      exchange contracts used to manage our foreign exchange risk where
      the cost of economic hedging is prohibitive or a cost effective
      market does not exist.

      Other income and expense for the first half of 2004 includes
      investment and interest income on its cash balances, marketable
      securities and notes receivable.  The Company also includes in this
      category any gains or losses associated with the sale of any surplus
      manufacturing equipment or other productive assets.  During the
      first half of 2004, the Company recorded a $2.4 million write-down
      in an investee in which has no influence.

      The Company's effective tax rate on continuing operations was 30%
      and 33% for the first half of 2004 and 2003, respectively.  The rate
      decline is principally the result of tax planning opportunities
      resulting from increased foreign profitability.  Should legislation
      which the Company relied on to effect the lower rate remain
      unchanged, this benefit is expected to last approximately 5 years.

      Financial Condition

      As of June 30, 2004, the Company had available $155.3 million in
      cash and cash equivalents, $26.0 million under international lines

                                       16
      


      of credit and $145.5 million under the restated and amended
      Revolving Credit Facility.  Management believes that this
      availability, together with cash flow from operations, will be
      adequate to meet the Company's current objectives for operations,
      research and development, capital additions for plant, equipment and
      systems and potential acquisitions.

      Net cash provided by operations was $47.5 million and $46.6 million
      for the six month period ending June 30, 2004 and 2003,
      respectively.  The Company's continued profitability, an increase in
      operating asset requirements in line with sales growth, and lower
      tax rates have all contributed to the improvement in cash flow from
      operating activities on a comparative basis.

      At June 30, 2004, consolidated accounts receivable were $234.0
      million, a decrease of $0.1 million from December 31, 2003.  The
      decline represents both an impact from foreign currency, as the
      June 30, 2004 rate of the Euro and several other currencies declined
      when compared to year-end.  Excluding foreign currency effects,
      receivables increased approximately $5.0 million.  This is
      attributable to local payment patterns and sales mix by country with
      no discernable change to practices, market, or customer risk
      profiles.

      At June 30, 2004, consolidated net inventories decreased $1.7
      million from December 31, 2003.  Included in the reported amount is
      approximately $2.6 million attributable to the acquisition of the
      controls business of Hematronix.  Inventories, net of divestitures,
      acquisitions and currency, increased by $4.6 million.  This increase
      represents builds for cyclical process chromatography orders and the
      launch of new products including instrumentation.

      Net capital expenditures totaled $29.1 million for the first six
      months of 2004 compared to $25.4 million for the same period of
      2003.  Capital expenditures represent the Company's investment in
      business systems, data communication, the addition and replacement
      of production machinery equipment and facility additions and
      leasehold improvements. All periods include reagent rental equipment
      placed with Clinical Diagnostics customers who then commit to
      purchase reagents for use.

      The Company continues to review possible acquisitions to expand both
      its Life Science and Clinical Diagnostics segments.  The Company
      routinely meets with the principals or brokers of the subject
      companies. We are evaluating a number of acquisitions on a preliminary
      basis, but it is not certain that any of these transactions will advance
      beyond the preliminary stages or be completed.  Should the Company
      make a material acquisition, it would most likely require an increase
      in borrowed funds.  In June 2004, the Company signed a letter of intent
      to acquire MJ GeneWorks, Inc. and its subsidiaries.  The acquisition
      has not been completed as of the date of this filing.  See Note 5.



                                       17
      

      The Board of Directors has authorized the Company to repurchase up
      to $18.0 million of the Company's common stock over an indefinite
      period of time.  Through June 30, 2004, the Company has cumulatively
      repurchased 1,179,272 shares of Class A Common Stock and 60,000
      shares of Class B Common Stock for a total of $14.7 million.  The
      Company's credit agreements restrict the Company's ability to
      repurchase its own stock. There were no share repurchases made
      during 2003 or 2004.  The repurchase is designed to both satisfy the
      Company's obligations under the employee stock purchase and stock
      option plans and to improve shareholder value.

      Item 3.   Quantitative and Qualitative Disclosures about Market Risk

      During the six months ended June 30, 2004, there have been no material
      changes from the disclosures about market risk provided in the
      Company's Annual Report on Form 10-K for the year ended December 31,
      2003.

      Item 4.  Controls and Procedures

      The Company maintains disclosure controls and procedures that are
      designed to ensure that information required to be disclosed in the
      Company's Exchange Act reports is recorded, processed, summarized and
      reported within the time periods specified in the Securities and
      Exchange Commission's rules and forms and that such information is
      accumulated and communicated to the Company's management, including its
      Chief Executive Officer and Chief Financial Officer, as appropriate, to
      allow for timely decisions regarding required disclosure.  In designing
      and evaluating the disclosure controls and procedures, management
      recognizes that any controls and procedures, no matter how well
      designed and operated, can provide only reasonable assurance of
      achieving the desired control objectives, and management is required to
      apply its judgment in evaluating the cost-benefit relationship of
      possible controls and procedures.

      As required by SEC Rule 13a-15(b), the Company carried out an
      evaluation, under the supervision and with the participation of the
      Company's management, including the Company's Chief Executive Officer
      and the Company's Chief Financial Officer, of the effectiveness of the
      design and operation of the Company's disclosure controls and
      procedures as of the end of the quarter covered by this report.  Based
      on the foregoing, the Company's Chief Executive Officer and Chief
      Financial Officer concluded that the Company's disclosure controls and
      procedures were effective at the reasonable assurance level.

      There has been no change in the Company's internal controls over
      financial reporting during the Company's most recent fiscal quarter
      that has materially affected, or is reasonably likely to materially
      affect, the Company's internal controls over financial reporting.
