   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.

   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.

   The Company purchased shares of ordinary stock of Sartorius AG, of
   Goettingen, Germany, a process technology supplier to the
   biotechnology, pharmaceutical, chemical and food and beverage
   industries for approximately $1.3 million during the three months
   ended March 31, 2004. The Company accounts for this investment using
   the cost method.

   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 and Other long-term liabilities, were as follows
   (in millions):

                                  2004        2003

   7.      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 upon a number of factors including the duration
   of the specific borrowing and is based upon either the Eurodollar,
   the Federal Funds effective or the Company corporate-based rate.


   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 include
   the dilutive effect of outstanding stock options of 820,000 and
   773,000 shares, for the three months ended March 31, 2004 and 2003,
   respectively.  Options to purchase 7,000 and 50,000 shares of common
   stock were outstanding during the three month periods ended
   March 31, 2004 and 2003 respectively, 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.

   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.  Under the 2003 Stock
   Option Plan, 306,990 shares were granted during the first quarter of
   2004.  Under the 1994 Stock Option Plan, 302,993 shares were granted
   during the first quarter of 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.

                                       6

   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,
   except per share data):

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

   For purposes of the pro forma disclosures, the estimated fair value of
   the options granted is amortized to expense over the options' vesting
   period. The fair value of options granted was estimated using the
   Black-Scholes model with the following weighted average assumptions:

   Expected dividend                      --          --

   The weighted average fair value of employee stock options granted
   during the three months ended March 31, 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 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

                                       7
   <page>
   authorized the sale of 1,890,000 shares of common stock under the
   plan.

   The Company sold 17,273 shares for $0.7 million and 18,641 shares for
   $0.6 million under the plan to employees for the three months ended
   March 31, 2004 and 2003, respectively.  At March 31, 2004, 251,966
   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 Ended
                                   March 31,
                               ------------------

   Expected life (in years)        .25       .25
   Expected dividend                --        --

   The weighted average fair value of those purchase rights granted
   during the three months ended March 31, 2004 and 2003 was $11.15 and
   $7.99, respectively.

   the year ended December 31, 2003 and this report for the quarter ended
   March 31, 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 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
                                       10
   <page>
   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 32% of our first quarter 2004 consolidated net sales are
   from the United States and approximately 68% 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 March 31, 2004 as well as the
   prior period.

   On a currency neutral basis, the diagnostic market is growing in the
   3% range 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 with
   reagents leading the 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. Growth in
   BSE testing will come from opening new testing markets.

   The following shows gross profit and expense items as a percentage of
   net sales:

   Critical Accounting Policies

   As previously disclosed in the Company's Annual Report on
   Form  10-K for the year ended December 31, 2003, the Company  has
   identified  accounting for income taxes, valuation of  long-lived
   and  intangible assets and goodwill, and valuation of inventories
   as  the  accounting  policies critical to the operations  of  the
   Company. For a full discussion of these policies, please refer to
   the Form 10-K.

   Corporate Results -- Sales, Margins and Expenses

   Net sales (sales) in the first quarter of 2004 rose 8.4% to $266.6
   million from $246.0 million in the first quarter of 2003. The positive
   impact to sales from a weakening US dollar represented $22.4 million.
   For the Company in total, on a currency neutral basis, sales remained
   essentially flat compared to the prior quarter.  The Clinical
   Diagnostics segment sales grew by 10% to $138.9 million, before
   adjustment to a currency neutral basis, while the Life Science segment
   sales grew 7%.  Each segment benefited by approximately 9% as a result
   of weakening US dollar on a comparative basis.  Clinical Diagnostics
   sales experienced sales growth for its quality control product line
   while sales declined in its blood Virus product line, in part due to a
   large first quarter 2003 bulk shipment absent from the current
   quarter.  Life Science sales experienced growth in its multiplex
   immunoassays, image analysis and expression proteomic reagents and
   apparatus.  Sales declined for the food science products as average
   selling prices declined in the very competitive BSE market and sales
   volume decreased for the segment's confocal microscopy products.

   Consolidated gross margins were 56.5% for the first quarter of 2004
   compared to 58.0% for the first quarter of 2003 and 56.3% for all of
   2003.  Clinical Diagnostics gross margin remained unchanged when
   compared to the first quarter of 2003.  Life Science gross margins
   declined in part due to lower average selling prices for the Company's
   BSE tests, which have been under competitive pricing pressure for
   several quarters.  The Company has lowered the average selling price
   on these tests to retain its leading market share.  Remaining declines
   in Life Science are due to a mix of higher royalty expenses and
   increased unfavorable manufacturing variances, due in part to the
   first quarter relocation of Life Science manufacturing into new
   facilities.

   Selling, general and administrative expenses (SG&A) represented 33.2%
   of sales for the first quarter of 2004 compared to 31.4% of sales in
   the prior period.  Both the Clinical Diagnostics and Life Science
   segments increased SG&A spending at growth rates similar to the
   Company's growth rate. Increased spending reflects higher costs for
   facilities, professional services for information technology

                                       12
   <page>
   improvements and other infrastructure investments and personnel costs.

   Product research and development expense increased 17.9% to $25.2
   million in the first quarter of 2004 compared to the prior quarter
   excluding $0.9 million of expense for acquired in-process research and
   development in the current quarter. Both Life Science and Clinical
   Diagnostics each increased their research and development expenditures
   by near equivalent amounts in absolute dollars.  Areas of development
   for the Company are proteomics, process chromatography, food safety,
   new diagnostic tests and expanded quality control systems.

   Corporate Results- Other Items

   Interest expense increased from the prior year by 8.6%.  This increase
   is the net effect of the Company increasing its average indebtedness
   from $112 million in the first quarter of 2003 to $235 million for the
   first quarter of 2004.  During the second half of 2003, the Company
   refinanced all of its debt, represented largely by its 11-5/8% bonds,
   and replaced it with new 7.5% bonds.  This has brought about a
   significant drop in the average borrowing rate.

   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.

   Other income and expense for the first quarter of 2004 includes higher
   interest income on cash balances of approximately $140 million
   representing the net proceeds from the $225 million bond financing
   which have not been fully employed for an acquisition or other
   corporate needs.  The Company also received a payment on the
   divestiture of product know-how which was transacted in a prior
   period, but was considered contingent at the time.  These items were
   offset as the Company recorded a $2.4 million write-down of an
   investment due to a recapitalization.

   The Company's effective tax rate was 28% and 33% for the three month
   periods ended March 31, 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 the benefit is
   expected to last approximately 5 years.

   As of March 31, 2004, the Company had available $141.5 million in cash
   and cash equivalents, $30.2 million under international lines of
   credit and $150.0 million under the restated and amended Revolving
   Credit Facility.  Management believes that the 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 an acquisition or
   acquisitions with a total value of approximately $200 million.

                                       13
   <page>
   Net cash provided by operations was $27.3 million and $21.7 million
   for the period ending March 31, 2004 and 2003, respectively.  The
   Company's continued profitability, lack of excessive additional
   operating asset requirements, and lower tax rates have all contributed
   to the improvement in cash flow from operations on a comparative
   basis.

   At March 31, 2004, consolidated accounts receivable were $228.9
   million, a decrease of $5.2 million from December 31, 2003.  The
   decline represents both an impact from foreign currency, as the March
   31, 2004 rate of the Euro declined when compared to year-end, and the
   essentially flat currency neutral sales.

   At March 31, 2004, consolidated net inventories remained virtually
   unchanged from December 31, 2003.  Included in the reported amount is
   approximately $2.6 million attributable to the acquisition of the
   controls business of Hematronix.  There was no substantial change in
   the mix of inventory held by operating segments.

   Net capital expenditures totaled $13.4 million for the first quarter
   of 2004 compared to $11.0 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.  Should the Company make a material acquisition it would
   most likely require an increase in borrowed funds.

   The Board of Directors has authorized the Company to repurchase up to
   $18 million of the Company's common stock over an indefinite period of
   time.  Through March 31, 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 three months ended March 31, 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.

                                       14

   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.
