   4.   GOODWILL

   The Company adopted Statement of Financial Accounting Standards
   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.  No goodwill was recorded or impaired during the three
   months ended March 31, 2003.


   5.   ACQUISITIONS

   On March 31, 2003, the Company purchased for cash the
   chromatography column manufacturing business of Verdot Industrie
   (Verdot) of Riom, France.  Bio-Rad acquired the outstanding
   shares of Verdot for approximately $6 million and will include
   these operations in its Life Science segment.

   6.   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, were as follows (in millions):

        January 1, 2003               $ 7.1
          Provision for warranty        3.0
          Actual warranty costs        (2.4)
                                       ----
        March 31, 2003                $ 7.7
                                       ====
   7.   LONG-TERM DEBT

   During the first quarter of 2003 the Company repurchased in the
   open market $6.7 million (par value) of its Senior Subordinated
   Notes due in 2007.  The price paid includes interest to February
   2004.  The total amount of interest, unamortized debt issue cost
   and unamortized original issue discount recognized as a result of
   the repurchase was $1.0 million and has been included in interest
   expense.

   8.   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

                                   5
<page>




   include the dilutive effect of outstanding stock options of
   773,000 and 859,000 shares, for the three month periods ended
   March 31, 2003 and 2002, respectively.

   Options to purchase 50,000 shares of common stock were
   outstanding for the three month period ended March 31, 2003 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 shares for the three month period ended March 31, 2002.


   9.   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.  No options
   have been issued to non-employees.

   In March of 2003, stockholders approved the 2003 Stock Option
   Plan of Bio-Rad Laboratories, Inc. (the Plan).  The Plan
   authorizes the grant to employees of incentive stock options and
   non-qualified stock options.  A total of 1,675,000 shares have
   been reserved for issuance and may be of either Class A or Class
   B Common Stock.  No options have been granted from this plan
   during the first quarter of 2003.

   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 stock option grants been determined
   pursuant to 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, except per
   share data):
                                                Three Months Ended
                                                     March 31,

                                   6

   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 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 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 18,641 shares for $0.6 million and 20,050 shares for
   $0.4 million under the plan to employees for the three months ended
   March 31, 2003 and 2002, respectively.  At March 31, 2003, 321,912
   shares remain authorized under the plan.

   The fair value of the employees' purchase rights since 1995 was
   estimated using the Black-Scholes model with the following assumptions
   for the three month periods ended March 31, 2003 and 2002
   respectively: no dividend yield for all periods; an expected life of
   three months for all periods; expected volatility of 37% and 34%; and
   risk-free interest rates of 1.01% and 1.68%.  The weighted average
   fair value of those purchase rights granted during the three months
   ended March 31, 2003 and 2002 was $7.99 and $6.46, respectively.


   10.  FOREIGN EXCHANGE LOSSES

   Foreign exchange losses include premiums and discounts on forward
   foreign exchange contracts and mark-to-market adjustments on foreign
   exchange contracts.

   11.  OTHER INCOME AND EXPENSE

   Other (income) and expense, net  includes the following components

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

   In the first quarter of 2002, the Company recorded a $2.0 million non-
   cash pre-tax charge reflecting the write-down of the Company's
   investment in Digilab, LLC.  This reduced the investment value to
   zero.

   12.  COMPREHENSIVE INCOME

   SFAS No. 130, "Reporting Comprehensive Income" requires disclosure of
   total non-stockholder changes in equity, which include unrealized
   gains and losses on securities classified as available-for sale under
   SFAS No. 115 "Accounting for Certain Investments in Debt and Equity
   Securities", foreign currency translation adjustments accounted for

   13.  SEGMENT INFORMATION

   Information regarding industry segments for the three months ended
   March 31, 2003 and 2002 is as follows (in millions):

   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
   reconciles total segment profit to consolidated income before taxes (in
   millions):

   14.  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.


   15.  NEW FINANCIAL ACCOUNTING STANDARDS

   In April 2002, the Financial Accounting Standards Board (FASB)issued
   Statement of Financial Accounting Standards (SFAS) No. 145, "Rescission
   of FASB Statements No. 4, 44 and 64, Amendment of FASB Statement No. 13,
   and Technical Corrections."  One of the major changes of this statement
   is to change the accounting for the classification of gains and losses
   from the extinguishment of debt.  The Company adopted SFAS No. 145 as of
   January 1, 2002 and will follow APB 30, "Reporting the Results of
   Operations -- Reporting the Effects of Disposal of a Segment of a
   Business, and Extraordinary, Unusual and Infrequently Occurring Events
   and Transactions" in determining whether such extinguishment of debt may
   be classified as extraordinary.  As a result of adoption, the expenses
   incurred in the repurchase of outstanding debt on the open market has
   been included in interest expense.  No other impact from adoption was
   recognized.

   SFAS No. 146 "Accounting for Costs Associated with Exit or Disposal
   Activities", was issued in June 2002 and addresses accounting for
   restructuring and similar costs.  SFAS 146 requires that a liability for
   costs associated with an exit or disposal activity be recognized and
   measured initially at fair value only when the liability is incurred.
   SFAS 146 is effective for exit or disposal activities that were
   initiated after December 31, 2002.  The adoption of SFAS 146 did not
   have any impact on the condensed consolidated financial statements of
   the Company.

   On December 31, 2002, the FASB issued SFAS No. 148, "Accounting for
   Stock-Based Compensation - Transition and Disclosure, an Amendment of
   FASB Statement No. 123."  This statement provides alternative methods of
   transition for companies who voluntarily change to the fair value-based
   method of accounting for stock-based employee compensation in accordance
   with SFAS No. 123, "Accounting for Stock-Based Compensation."  The
   statement requires prominent disclosures in both annual and interim
   financial statements about the method of accounting for stock-based
   compensation and the effect of the method used on reported results.  The
   Company has adopted the disclosure requirements as required by the
   statement.

   The Company continues to account for stock-based compensation using the
   intrinsic value method in accordance with the provisions of Accounting
   Principles Board Opinion No. 25, "Accounting for Stock Issued to
   Employees," elected under SFAS No. 123, as amended.  As a result, the
   adoption of SFAS No. 148 did not have any impact on the condensed
   consolidated financial statements of the Company (see Note 9).

   Critical Accounting Policies

   As previously  disclosed in the  Company's Annual Report  on Form
   10-K  for the  year  ended December  31,  2002, the  Company  has
   identified  accounting for income  taxes, valuation of long-lived

   Forward Looking Statements

   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.  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
   substantial leverage and ability to service our debt; competition
   in and government 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.

   The Company manufactures and supplies the life science research,
   healthcare, analytical chemistry and other markets with a broad
   range of products and systems used to separate complex chemical
   and biological materials and to identify, analyze and purify
   their components.

             Three Months Ended March 31, 2003 Compared to
                   Three Months Ended March 31, 2002

   Corporate Results - Sales, Margins and Expenses

   Net sales (sales) in the first quarter of 2003 rose 17% to 246.0
   million from $210.2 million the first quarter of 2002.  The
   positive impact to sales from a weakening US dollar represented
   $21.9 million of the $35.8 million increase in sales.  The Life
   Science and Clinical Diagnostics segments each grew by 16.9%
   achieving sales of $117.5 million and $126.1 million,
   respectively.  The positive impact from a weakening US dollar
   represented $11.3 million of Life Science's total sales growth
   and $10.5 million of the Clinical Diagnostics sales growth.  The
   contributors to organic growth in Life Science were the process
   chromatography, food safety and DNA amplification product lines.
   Clinical Diagnostics sales growth was generated in several areas
   including quality controls, blood virus screening, autoimmune
   testing and diabetes monitoring.

   Consolidated gross margins were 58.0% for the first quarter of
   2003 compared to 57.7% for the first quarter of 2002 and 57.1%
   for all of 2002.  The gross margin in Life Science declined
   slightly.  The gross margin decline is attributable to several
   factors without any single one indicating a change in trends.
   Included are food safety product average pricing, factory
   utilization versus planned levels and sales mix.  This decline
   was offset by increased gross margins in Clinical Diagnostics.
   Clinical Diagnostics gross margin improved primarily due to US
   sourced products sold into foreign markets, above average royalty
   and license revenue, and improved factory utilization from higher
   sales and production.

   Selling, general and administrative expense (SG&A) represented
   31.4% of sales for the first quarter of 2003 compared to 31.3% of
   sales in the prior period.  Both Life Science and Clinical
   Diagnostics increased spending in absolute dollars with Life
   Science growing SG&A at a rate higher than sales growth and
   Clinical Diagnostics at a rate lower than sales growth.  Life
   Science spending has been for personnel, advertising, facilities
   and new product marketing.  Although the Company is making an
   investment in SG&A infrastructure in 2003, a longer term goal for
   management remains a gradual reduction in SG&A spending as a
   percent of sales.














                                   11
<page>








   Product research and development expense increased 5.7% to $21.4
   million in the first quarter of 2003 as compared to the first
   quarter of 2002.  Life Science and Clinical Diagnostics each
   increased their research and development expenditures in line
   with development plans in the area of proteomics, process
   chromatography, food safety, new diagnostic tests and expanded
   quality control systems.

   Corporate Results - Other Items

   Interest expense decreased from the prior year largely as a
   result of debt reductions that occurred throughout 2002.
   Included in the first quarter of 2003 is $1.0 million of costs to
   repurchase $6.7 million of the Company's outstanding subordinated
   debt.  No equivalent amount was included in the first quarter of
   2002.  Other (income) expense, net in the first quarter of 2003
   is mainly interest income compared with a $2.0 million non-cash
   pre-tax expense for the impairment of an investment and interest
   income in the first quarter of 2002.

   Exchange gains and losses consist of the premiums and discounts
   on forward foreign exchange contracts used to hedge against
   future movements in intercompany accounts receivable and accounts
   payable, and the revaluation of intercompany accounts receivable
   and payable where the cost of hedging is prohibitive or a cost
   effective market does not exist.  Gains and losses remained
   virtually unchanged for the first quarter of 2003 and 2002.

   The Company's effective tax rate was 33% and 32% for the periods
   March 31, 2003 and 2002, respectively.  The rate rose as tax
   credits represented a smaller percentage of total taxable income.

   Financial Condition

   The Company, as of March 31, 2003, had available approximately
   $100.0 million under its principal revolving credit agreement and
   $20.4 million under various foreign lines of credit.  Cash and
   cash equivalents available were $25.2 million.  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 and
   investment in facilities, equipment and systems.

   Net cash provided by operations was $21.7 million and $18.1
   million for the first quarter of 2003 and 2002, respectively.
   During the current quarter the Company purchased in the open
   market and retired $6.7 million of its Senior Subordinated Notes
   due in 2007.  The Company will assess the opportunity to retire
   the remaining outstanding principle balance as the notes become
   available.

   At March 31, 2003, consolidated net receivables increased by $1.7
   million from December 31, 2002.  This increase reflects the
   increased value of foreign receivables as the US dollar continued

                                   12
<page>







   to weaken from year-end 2002.  On a constant currency basis,
   receivables actually fell as they are represented by lower cost
   disposables and apparatus products and less equipment which
   generally is characterized by longer collection periods and
   conditions precedent to payment.

   At March 31, 2003, consolidated net inventories increased by $6.5
   million.  A third of the increase is attributable to the
   appreciation of inventory denominated in foreign currency.  The
   remaining inventory increase is largely attributable to Clinical
   Diagnostics and in particular the Quality Controls product line
   which is characterized by long lead times and infrequent batch
   production necessary to meet customer specifications.

   Net capital expenditures totaled $11.0 million for the first
   three months of 2003 compared to 8.4 million for the same period
   of 2002.  Capital expenditures for the quarter include reagent
   rental equipment placed with Clinical Diagnostics customers who
   then commit to purchase the Company's diagnostic reagents.  The
   remaining expenditures represent additions to production
   equipment, investment in data communication and business systems
   and expanded facilities.  The most notable new facility is the
   manufacturing, laboratory and general office space being
   constructed on Company-owned land in Hercules, California.  The
   estimated cost of this new 166,000 square foot facility is $25
   million and is scheduled for occupancy early the first quarter of
   2004.  As of March 31, 2003 approximately $3.5 million has been
   capitalized on the project.


   Item 3.   Quantitative and Qualitative Disclosures
             About Market Risk

   During the three months ended March 31, 2003, 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, 2002.

   Item 4.   Controls and Procedures

   The Company's chief executive officer and its principal financial
   officer after evaluating the effectiveness of the Company's
   disclosure controls and procedures (as defined in Exchange Act
   Rules 13a-14(c) and 15-d-14(c)) as of a date within 90 days of
   the filing date of the quarterly report (the "Evaluation Date")
   have concluded that as of the Evaluation Date, the Company's
   disclosure controls and procedures were adequate and effective to
   ensure that material information relating to the Company and its
   consolidated subsidiaries would be made known to them by others
   within those entities during the period in which this quarterly
   report was being prepared.





                                   13
<page>







   There were no significant changes in the Company's internal
   controls or in other factors that could significantly affect the
   Company's disclosure controls and procedures subsequent to the
   Evaluation Date, nor any significant deficiencies or material
   weaknesses in such disclosure controls and procedures requiring
   corrective actions.  As a result, no corrective actions were
   taken.
