Item 5.  Other Events.

         On October 31, 1997, in connection with Beckman Instruments, Inc.'s
(the "Company" or "Beckman") acquisition (the "Acquisition") of Coulter
Corporation ("Coulter"), the Company entered into a $1.3 billion credit
facility, consisting of an $800.0 million revolving credit facility (the
"Revolving Credit Facility") and a $500.0 million term loan facility (the "Term
Loan").

         As of February 1, 1998, there were $750.0 million outstanding under the
Revolving Credit Facility and $300.0 million outstanding under the Term Loan. In
addition, as of February 1, 1998, there was $100.0 million of the Company's
7.05% Debentures due 2026 (the "Old Debentures") outstanding. The Company
expects to incur $400.0 million of new indebtedness (the "Proposed Financing")
to prepay all of the Term Loan borrowings and to finance a tender offer of any
and all of its Old Debentures. In the event that less than all of the Old
Debentures are tendered in such tender offer, an amount equal to the untendered
principal amount thereof will be applied to repay a portion of the Revolving
Credit Facility.

         In connection with the Proposed Financing, the Company prepared certain
financial statements and other information for Coulter for the six months ended
September 30, 1996 and 1997, certain financial statements for Coulter for the
seven months ended October 31, 1997 and certain pro forma financial statements
of the Company. Such information is provided in this Report under the captions:

</TABLE>
 
     Coulter experienced net sales growth of 4.3% compared to the comparable
period in the prior year. Instrument sales increased 16.0% while reagent sales
were relatively unchanged. The release of the GEN*S and AC*T series of
hematology products during 1997 mainly accounted for the increase in instrument
sales, while reagent sales were adversely affected by increased discounting in
the U.S. and a strengthening dollar in overseas markets.
 
     Gross profit margin as a percentage of sales decreased by less than 1% as
higher selling prices on GEN*S products were offset by increased warranty costs
in direct sales markets. In addition, competitive market pressures in the U.S.
and international markets contributed to overall lower sales prices on
instrument and reagent products, resulting in a decrease in gross profit.
 
                                       1
<PAGE>   4
     Selling, general, and administrative expenses as a percentage of sales
decreased by 1.6% primarily due to reduced expenses in the international
operations resulting from cost reduction measures and a strengthening U.S.
dollar. Research and development expenses as a percentage of sales decreased
2.5%, and in absolute dollars $6.2 million, due to a reorganization to improve
productivity and efficiency.
 
     The net increase in non-operating expense of $2.7 million is attributable
to an increase in foreign exchange gains in the U.S., offset by Coulter's
portion of expenses relating to its investments in two development stage
companies.

     For the six months ended September 30, 1997, Coulter's income before
provision of income taxes and net income increased $8.4 million and $6.1
million, respectively, compared to the comparable period in the prior year.

CASH FLOW FOR COULTER FOR SIX MONTHS ENDED SEPTEMBER 30, 1997
 
     For the six months ended September 30, 1997, net cash provided by operating
activities was $29.8 million compared with $38.0 million of cash used in
operating activities for the comparable period in the prior year. An increase in
net income of $6.1 million and fluctuations in accounts receivable, inventories,
other assets, and accrued liabilities accounted for the increase. A significant
decrease in collection days in the U.S. contributed to a $28.9 decrease in
accounts receivable compared to a $16.6 million decrease in the comparable
period of the prior year. Inventory growth was $10.3 million, compared to $27.9
million in the prior year period, as inventory build up was reduced due to the
release of the GEN*S and AC*T products in fiscal year 1997. In addition, a
stronger U.S. dollar in overseas markets, especially Europe and Japan, also
contributed to the reduction in inventory. Other assets increased $2.2 million,
primarily due to a $4.2 million investment by Coulter for a 6.6% interest in
Lab-Interlink, Inc. Accrued liabilities decreased $0.5 million, compared to a
decrease of $26.6 million in the prior year period. Payments relating to the
Success Sharing bonus program and the termination of Coulter's defined benefit
plan accounted for the decrease in the comparable period of the prior year.
 
     For the six months ended September 30, 1997, net cash used in investing
activities was $13.4 million compared with $27.9 million of cash used in
investing activities for the comparable period in the prior year. Capital
expenditures were $14.4 million, a reduction of $22.5 million from the prior
year period, mainly caused by a decrease in spending for computer hardware and
software. Offsetting the decrease in capital expenditures was an increase of
$6.2 million in cash used from investing activities resulting from an increase
in Coulter's leasing business due to the release of new products during the six
months ended September 30, 1997.
 
     Net cash used in financing activities for the six months ended September
30, 1997 was $16.2 million compared to $47.9 million of net cash provided by
financing activities for the comparable period in the prior year. A reduction of
$54.0 million in proceeds from long-term debt coupled with an increase of $17.7
million in principal payments largely accounted for the increase in cash used in
financing activities.

                         PRO FORMA FINANCIAL STATEMENTS
 
     The following unaudited pro forma balance sheet as of December 31, 1997 has
been prepared to illustrate the effect of the Proposed Financing and the
application of the net proceeds therefrom, as if they had occurred on December
31, 1997. The following unaudited pro forma statement of operations of Beckman
and Coulter for the year ended December 31, 1997 has been prepared to illustrate
the effect of the Acquisition, the Proposed Financing and the application of the
net proceeds therefrom, as if they had occurred as of January 1, 1997. The pro
forma statement of operations for the year ended December 31, 1997 includes the
results of Coulter for the ten months ended October 31, 1997. The results of
Coulter for the two months ended December 31, 1997 are included in Beckman's
consolidated statement of operations for the year ended December 31, 1997, as
filed with the Securities and Exchange Commission in the Company's Annual Report
on Form 10-K on February 11, 1998. The pro forma adjustments also give effect to
the spin-off of Coulter's interest in Coulter Pharmaceutical, Inc. ("Coulter
Pharmaceutical") and a spin-off of a portion of the capital stock of Coulter
Cellular Therapies, Inc. ("Coulter Cellular"), which were completed prior to the
Acquisition, as if such spin-offs were completed prior to January 1, 1997. The
pro forma adjustments, and the assumptions on which they are based, are
described in the accompanying notes to the Pro Forma Financial Statements.
 
     The unaudited pro forma financial statements are presented for illustrative
purposes only and are not necessarily indicative of the consolidated financial
position or consolidated results of operations of the Company that would have
been reported had the Acquisition, the Proposed Financing and the application of
the net proceeds therefrom occurred on the dates indicated, nor do they
represent a forecast of the consolidated financial position of the Company at
any future date or the consolidated results of operations of the Company for any
future period. Furthermore, no effect has been given in the pro forma statement
of operations for synergies or costs, if any, that may be realized through the
combination of Beckman and Coulter. The pro forma financial statements,
including the notes thereto, should be read in conjunction with the Consolidated
Financial Statements of the Company, as filed with the Securities and Exchange
Commission in the Company's Annual Report on Form 10-K for the year ended
December 31, 1997.

                    NOTES TO PRO FORMA FINANCIAL STATEMENTS
 
     The pro forma financial statements and related notes give effect to the
Acquisition accounted for as a purchase. The pro forma balance sheet assumes
that the Proposed Financing and the application of the net proceeds therefrom
were completed as of December 31, 1997 and the pro forma statement of operations
assumes that the Acquisition, the Proposed Financing and the application of the
net proceeds therefrom were completed on January 1, 1997. The Acquisition was
consummated on October 31, 1997. Accordingly, the historical financial
statements for the Company for the fiscal year ended December 31, 1997 include
the results of Coulter from November 1, 1997, and the pro forma statement of
operations for the year ended December 31, 1997 also includes the results of
Coulter for the ten months ended October 31, 1997.
 
     All interim financial data used to develop the pro forma balance sheet and
statement of operations are unaudited, but in the opinion of management, reflect
all adjustments necessary (consisting only of normal recurring entries) for a
fair presentation thereof.
 
     The unaudited pro forma statement of operations is not necessarily
indicative of operating results which would have been achieved had the
Acquisition, the Proposed Financing and the application of the net proceeds
therefrom been consummated as of January 1, 1997 and should not be construed as
representative of future earnings.
 
     Under purchase accounting, the total acquisition cost was allocated to
Coulter's assets and liabilities based on their relative fair values. The final
allocations may be different from the amounts reflected herein. The Company does
not believe that the final purchase price allocation will differ significantly
from the preliminary purchase price allocation recorded in fiscal 1997. The
Company's analysis resulted in an allocation of $282.0 million to in-process
research and development which, under generally accepted accounting principles,
was expensed immediately after the Acquisition was completed. For additional
information on the allocation of the purchase price, see Note 3 to Consolidated
Financial Statements of Beckman, as filed with the Securities and Exchange
Commission in the Company's Annual Report on Form 10-K for the year ended
December 31, 1997.
 
     The pro forma statement of operations for the year ended December 31, 1997
excludes the $282.0 million write-off of in-process research and development and
the $59.4 million restructuring charge, as they are non-recurring charges
associated with the Acquisition.
 
     The pro forma basic net earnings per share is based on the weighted average
number of common shares of Beckman during the period ended December 31, 1997 and
the pro forma diluted net earnings per share reflects the impact of dilutive
securities issued and outstanding.
 
     The following adjustments were recorded in the pro forma financial
statements:
 
           (a) Reflects financing fees and expenses related to the Proposed
     Financing estimated to be $4.8 million, which will be capitalized and
     amortized over the term of such debt.
 
           (b) To write-off unamortized financing fees and expenses on
     refinanced debt of Beckman and Coulter, including 100% of the Old
     Debentures. Such write-off will vary if less than 100% of the Old
     Debentures are tendered.
 
           (c) Reflects the tax effect of the pro forma adjustments. Goodwill
     amortization of $7.8 million for fiscal 1997 and the $282.0 million
     write-off of in-process research and development are not deductible for tax
     purposes. The effective tax rate of 38% for fiscal 1997 was applied to the
     other pro forma adjustments described.
 
           (d) Reflects the increase in debt as a result of the Proposed
     Financing and the reduction in debt upon application of the proceeds from
     the Proposed Financing to pay down the existing Term Loan and the Old
     Debentures.
 
           (e) Reflects ten months of operations for the period ended October
     31, 1997.
 
           (f) The pro forma adjustments to the statement of operations do not
     reflect the write-off of financing fees and expenses on refinanced debt of
     Beckman and Coulter as they will be recorded as extraordinary charges, net
     of tax. See (b), above.

<PAGE>   11
 
              NOTES TO PRO FORMA FINANCIAL STATEMENTS (CONTINUED)
 
           (g) Represents additional cost of sales as a result of a step-up in
     the basis of Coulter's inventory upon allocation of the acquisition cost.
 
           (h) Reflects the amortization of goodwill of $7.8 million and
     intangible assets of $13.5 million recorded as a result of the Acquisition.
     Amortization of intangible assets was calculated on a straight-line basis
     over periods ranging from 15-30 years. Amortization of goodwill was
     calculated on a straight-line basis over 40 years.
 
           (i) To eliminate the one-time write-off of $282.0 million of
     in-process research and development identified in the purchase price
     allocation of the Acquisition. The in-process research and development is
     based upon the economic value of projects in process, which cannot be
     capitalized under generally accepted accounting principles.
 
           (j) To eliminate a non-recurring restructuring charge of $59.4
     million recorded in fiscal 1997 for estimated costs for closing duplicate
     facilities of Beckman which, in the opinion of management, have no further
     useful life as a result of the Acquisition, and for implementation of
     operating efficiencies, and certain other costs.
 
           (k) Reflects interest expense for ten months at an assumed average
     rate of 7.25% on approximately $1,100 million of additional outstanding
     debt incurred to complete the Acquisition less amounts of Beckman and
     Coulter debt repaid with the proceeds of such additional debt. Also gives
     effect to the Proposed Financing and the application of the net proceeds
     therefrom. Excludes approximately $4.5 million of interest expense due to
     the fact that the incremental debt was assumed to be net of the $75.0
     million paydown resulting from the Company's sale of financial assets,
     primarily consisting of equipment subject to customer leases and lease
     receivables. For each 0.25% change in assumed average interest expense on
     the outstanding indebtedness, annual pro forma interest expense would
     change by approximately $2.3 million.
 
           (l) Reflects the amortization of $4.8 million of debt financing fees
     and expenses incurred in connection with the Proposed Financing over an
     assumed 7 1/2-year term.
 
           (m) Reflects the elimination of Coulter's proportionate share of the
     results of operations of Coulter Pharmaceutical and Coulter Cellular (net
     of the portion of Coulter Cellular which was retained) included in
     Coulter's historical results of operations. Prior to the Acquisition,
     Coulter distributed as dividends to its stockholders 100% of its interest
     in Coulter Pharmaceutical and two-thirds of its 68% equity interest in
     Coulter Cellular.

                          INDEPENDENT AUDITORS' REPORT
 
To the Stockholders of Coulter Corporation:
 
     We have audited the accompanying consolidated statements of operations,
stockholders' equity and cash flows of Coulter Corporation and subsidiaries (the
Company) for the seven months ended October 31, 1997. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     As discussed in Note O, the stockholders of the Company sold all of their
issued and outstanding shares of Class A Common Stock and Class B Common Stock
to Beckman Instruments, Inc. This transaction has resulted in a gain to the
stockholders; however no adjustments to current assets or liabilities have been
reflected in the consolidated financial statements.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the results of operations of Coulter
Corporation and subsidiaries and their cash flows for the seven months ended
October 31, 1997 in conformity with generally accepted accounting principles.

and cash flows for each of the three years in the period ended March 31, 1997.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Coulter
Corporation and subsidiaries as of March 31, 1997 and 1996, and the results of
their operations and their cash flows for each of the three years in the period
ended March 31, 1997 in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE A -- NATURE OF OPERATIONS
 
     Coulter Corporation and subsidiaries (the "Company") is engaged in the
business of developing, manufacturing, distributing, financing and servicing
certain medical equipment (predominantly hematology instruments) and related
consumable products used in the healthcare industry, research centers and
universities. The Company's principal markets are North America, Europe and the
Far East.
 
     The Company's future sales and profitability are largely dependent upon its
ability to continue to develop, manufacture, market, finance and service certain
medical equipment and related consumable products as described above. Sales can
be significantly affected by a variety of factors, including, among other
things, the timing of new product development, the availability of competing
products, and competitor strategies to expand market share. Certain raw
materials and components used in the manufacture of the Company's products are
available from limited sources. Changes in raw material suppliers could result
in delays in production and higher raw material costs.
 
NOTE B -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
     The consolidated financial statements include the accounts of Coulter
Corporation and all domestic and foreign subsidiaries. All significant
intercompany accounts and transactions have been eliminated in consolidation.
Certain 1996 balances have been reclassified to conform to the 1997
presentation.
 
  Revenue Recognition
 
     In general, revenue is recognized when a product is shipped. When a
customer enters into an operating-type lease agreement, revenue is recognized
over the life of the lease. Under a sales-type lease agreement, revenue is
recognized at the time of shipment with interest income recognized over the life
of the lease. Service revenues are recognized ratably over the life of the
service agreement or as service is performed, if not under contract.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Cash Equivalents
 
     Cash equivalents are short-term, highly liquid investments that have an
original maturity of three months or less.
 
  Inventories
 
     Inventories are stated at the lower-of-cost or market (principally using
the first-in, first-out method). Components of inventory cost include materials,
labor and manufacturing overhead. In evaluating whether inventory is stated at
the lower of cost or market, management considers such factors as inventory on
hand,

  Finance Receivables
 
     For leases that qualify as capital leases under Statement of Financial
Accounting Standards No. 13, the Company records in its consolidated balance
sheets the gross lease receivable and estimated residual value of the leased
equipment reduced by the unearned lease income and allowance for doubtful
accounts. The unearned lease income is ratably recognized as revenue so as to
reflect a constant periodic rate of return on the net investment over the term
of the leases, usually five years. Fees and costs related to the establishment
of a lease are recognized as an adjustment to the yield of the related lease
ratably over the life of the lease.
 
     Most equipment leases include service contracts and agreements to provide a
specified quantity of consumable products at a fixed price (payable monthly)
over the term of the lease. All income from these contracts is recognized as the
services are rendered and the consumable products are provided.
 
     The portfolio of lease receivables is reviewed by the Company to determine
an appropriate allowance for doubtful accounts balance. The allowance for
doubtful accounts includes management's estimate of the amounts expected to be
lost on specific leases and for losses on other as of yet unidentified leases
included in direct finance lease receivable at March 31, 1997 and 1996. In
estimating the potential losses on leases, management relies on historical
experience by lease type and current industry trends. The amounts that the
Company will ultimately realize could differ materially in the near term from
the amounts assumed in arriving at the allowance for doubtful accounts reported
in the consolidated financial statements at March 31, 1997 and 1996.

     Depreciation is provided in amounts sufficient to allocate the cost of
depreciable assets to operations over their estimated service lives principally
using the straight-line method. The estimated service lives are as follows:
 
<TABLE>
              <S>                                                    <C>

</TABLE>
 
     Leaseholds and leasehold improvements are amortized on a straight-line
basis over the shorter of the lives of the leases or the improvements (generally
five years). Equipment is leased to others under operating lease terms ranging
from one to five years which include cancellation provisions. Such equipment is
recorded at cost and is generally depreciated over five years, using the
straight-line method of depreciation.
 
  Accrued Liabilities
 
     Accrued liabilities consist of obligations that are recorded when expenses
are incurred. As of March 31, 1997 and 1996, such liabilities are as follows (In

  Recently Issued Accounting Standards
 
     The Company adopted Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-lived Assets and for Long-lived Assets to
be Disposed Of" ("SFAS 121") in fiscal year 1997. SFAS 121 establishes
accounting standards for recording the impairment of long-lived assets, certain
identifiable intangibles and excess of cost over fair value of net assets
acquired (goodwill). The adoption of SFAS 121 had no impact on the Company's
financial position or the results of its operations.
 
  Excess of Cost Over Fair Value of Net Assets Acquired
 
     Excess of cost over fair value of net assets acquired (goodwill) is stated
on the basis of cost and is amortized, principally on a straight-line basis,
over the estimated future periods not exceeding twenty years. Such cost is
reviewed for impairment based on an assessment of future operations to ensure
that it is appropriately valued.
 
  Estimated Warranty Costs
 
     The Company's warranty policy provides for repairs or replacements due to
defects in materials and workmanship in instrument products it manufactures for
a period of up to one year from the date of sale. Accordingly, a provision is
made for the cost of such anticipated warranty expense by a charge to operations
in the period of sale.

  Income Taxes
 
     The Company recognizes deferred tax assets and liabilities for the expected
future tax consequences of temporary differences between the financial reporting
and tax bases of assets and liabilities.
 
  Unearned Service Contract Revenue
 
     The Company sells contracts to provide repair service on its equipment for
specified terms. The customer pays for the contract prior to the service being
rendered. The contract amount is recorded as unearned service contract revenue
and the deferred income is amortized to operations on a straight-line basis over
the term of the contract, which is generally one to five years.
 
  Research and Development Costs
 
     Research and development costs are charged to operations as incurred.
 
  Disclosures about Fair Value of Financial Instruments
 
     The Company's financial instruments include cash, cash equivalents, notes
payable, foreign bank overdraft facilities, long-term debt and forward
contracts. Each of the financial instrument's carrying value approximates fair
value mainly due to their short-term nature, except for long-term debt (See Note
F).

     The Company maintains bankers acceptances and a note payable revolving
credit agreement (the "Credit Agreement") up to a maximum of $60,000,000
principal amount of domestic and Eurodollar loan borrowings. This facility also
allows the Company to enter into forward contracts for the sale of foreign
currency (See Note G). The maximum borrowing amount is the lesser of $60,000,000
or the borrowing base, as defined, provided that the aggregate amount of issued
and unexpired letters of credit and drafts do not exceed

NOTE F -- LONG-TERM DEBT (CONTINUED)
$10,000,000. The Credit Agreement expires in August 1998. At March 31, 1997,
borrowings under the Credit Agreement of $50,054,000 were classified as
long-term debt. At March 31, 1996, borrowings of $9,700,000 were outstanding and
classified as current maturities of long-term debt.
 
     Under the Credit Agreement, interest payable on the domestic note payable
is at the prime rate in effect for each interest period. Interest payable on the
Eurodollar and bankers acceptances is variable based on the LIBOR rate plus up
to 1.00% per annum.
 
     The Credit Agreement is secured by certain domestic assets of the Company
and a licensing agreement relating to the use and benefit of certain intangibles
of the Company. The Credit Agreement is also guaranteed by the stockholders of
the Company.
 
     The Credit Agreement contains certain covenants related to minimum
requirements for the maintenance of tangible net worth plus subordinated
indebtedness, maximum inventory to sales ratio, leverage ratio, consolidated
earnings before interest and taxes to net interest expense, intercompany
indebtedness and limitations on capital expenditures, investments and other
domestic indebtedness.
 
     The Company is also restricted from making any distributions to the
stockholders. At March 31, 1997, the Company is in compliance with all required
covenants.
 
     Based on the borrowing rates currently available to the Company for notes
payable and debt with similar terms and average maturities, management has
estimated the fair value of long-term debt to be $192,330,000 at March 31, 1997
and $140,745,000 at March 31, 1996.
 
NOTE G -- DISCLOSURE ABOUT DERIVATIVE FINANCIAL INSTRUMENTS
 
     At March 31, 1997, 1996 and 1995, the Company had outstanding foreign
currency forward contracts which typically mature within one year. The purpose
of these contracts is to hedge the Company's foreign exchange exposure with
respect to foreign currency cash flows received from foreign subsidiaries. The
Company does not speculate in the foreign exchange market. The forward contracts
require the Company to sell foreign currencies at a contracted exchange rate. As
provided by the Credit Agreement, the Company is committed to sell such foreign
currencies to the bank. At March 31, 1997, 1996 and 1995 these sale commitments
were $64,552,000, $74,523,000, and $86,865,000 respectively. Additionally, the
Company is committed to sell $9,490,000, $12,801,000 and $16,708,000 in foreign
currencies to another bank as of March 31, 1997, 1996 and 1995, respectively.
Foreign exchange contracts are valued at the spot rate on March 31, 1997, 1996
and 1995, which approximates the quoted market rate. The difference between the
spot rate at inception of the foreign currency forward contract and the spot
rate at the consolidated balance sheets date results in an unrealized gain or
loss. The premium or discount represents the difference between the contracted
rate and the spot rate at the date of inception, and is amortized over the life
of the contract on a

NOTE H -- INVESTMENT IN JOINT VENTURES
 
     In February 1995, Coulter Pharmaceutical, Inc. ("CPI"), was organized and
established for the purpose of researching, developing and marketing certain
potential cancer-curing products. As of March 31, 1997, a joint-venture partner
and other investors have contributed $63,624,000 in cash for an 84% ownership
interest. The Company contributed certain technology (with no net book value) in
exchange for a 16% and 51% ownership interest in CPI as of March 31, 1997 and
1996, respectively. As a result of cash contributions from certain outside
investors, the Company recorded $3,306,000, $7,203,000, $1,384,000 and
$1,667,000 as other income in the consolidated statements of income for the

of operations for the seven months ended October 31, 1997 and for the years
ended March 31, 1997, 1996 and 1995, respectively. Management believes that the
Company has the ability to significantly influence the operating and financial
policies of CPI.
 
     CPI executed a public offering of its stock during 1997. At March 31, 1997,
the market value of the Company's investment in CPI totalled $15,203,000. This
amount exceeds the carrying value of the Company's investment by $11,649,000.

therapeutic monoclonal antibodies. The Company contributed certain technology
(with no net book value) in exchange for a 68% ownership interest in CCTI. A
joint-venture partner contributed cash of $4,675,000 in exchange for the
remaining 32%. As a result of the joint-venture partner's contribution, the
Company recorded $3,179,000 as other income in the consolidated statements of
operations at March 31, 1997. The remaining contribution of $1,496,000 was
recorded as minority interest. From February 1997 to September 1997, CCTI was
consolidated with the Company; however, at October 31, 1997, CCTI was accounted
for using the equity method of accounting.
 
     CCTI incurred losses of $1,935,000 and $246,000 for the seven months ended
October 31, 1997 and for the two months ended March 31, 1997, respectively,
whereby the Company's proportionate share of $1,316,000 and $167,000,
respectively, were charged to the consolidated statements of income for the
seven months ended October 31, 1997 and for the year ended March 31, 1997,
respectively. At March 31, 1997, CCTI had a cash balance of $4,358,000; other

4,900,000 shares, respectively. Such stock had a book value of $5,833,000 at
October 31, 1997.
 
NOTE I -- BUSINESS ACQUISITION
 
     On June 30, 1995, the Company acquired Immunotech, S.A. and subsidiaries
("IOT") which is engaged in the research, development, manufacturing and
distribution of monoclonal antibodies. The principal office of IOT is located in
Marseille, France. This business acquisition was accounted for under the
purchase method of accounting. The total cost of this acquisition was
$25,444,000 which exceeded the fair value of net assets acquired of IOT by
$13,195,000. The excess of cost over fair value of net assets acquired
(goodwill) is recorded in other assets in the consolidated balance sheets and is
being amortized on a straight-line basis over twenty years.
 
     The Company acquired 97% of the common stock and 100% of the outstanding
warrants of IOT. The purchase price was paid in cash, except for $2,000,000
which will be paid in two equal interest-free installments in fiscal years 1998
and 1999. The unpaid purchase price is included in current and long-term debt in
the consolidated balance sheets.
 
     The following summarizes the results of operations of the Company on a

NOTE K -- RESTRUCTURING CHARGES
 
     For the year ended March 31, 1997, the Company recorded estimated domestic
and foreign restructuring charges of $5,947,000. The objective of restructuring
is to reduce future costs and improve operating results. Restructuring included
the termination of certain employees and the discontinuance of certain research
and development activities. The charges consisted primarily of severance and
retirement incentive pay; the cost of extended employees' benefits; and
consulting fees. The Company believes that the accrued restructuring charge is
adequate to cover associated costs. These restructuring charges were included in
accrued liabilities in the consolidated balance sheets at March 31, 1997. The
function and number of employees terminated were as follows:

total sale price of approximately $2,640,000 in cash.
 
NOTE M -- BENEFIT PLANS
 
  Postretirement Benefits for Domestic Employees
 
     The Company provides a Healthcare Benefits and Life Insurance Plan (the
"Plan") for retired domestic employees. Substantially all of the Company's
employees become eligible for benefits when they reach the age of 55 and meet
certain service requirements while working for the Company. Generally,
healthcare benefits are provided to individuals when they or their spouse become
eligible for Medicare benefits. Prior to eligibility for Medicare, retirees may
elect coverage if they pay the required participants' contribution.
 
     The domestic accumulated postretirement benefit obligation represents the
present value of the estimated future benefits payable to current retirees and a
pro rata portion of estimated benefits payable to active employees after
retirement. The domestic postretirement benefit cost recorded in the

     Annual net periodic postretirement benefit costs were calculated using the
assumed discount rate of 7.50% for the seven months ended October 31, 1997,
7.75% for fiscal 1997, 8.50% for fiscal 1996 and 8.25% for fiscal 1995. The
accumulated postretirement benefit obligation was determined by using a discount
rate of 7.75% at March 31, 1997 and 1996.
 
     If the healthcare cost trend rate increased by an additional 1.0%, the
accumulated postretirement benefit obligation would have increased by $5,662,000
(or 19%) as of March 31, 1997 and $4,571,000 (or 16%) as of March 31, 1996. The
aggregate of the service and interest cost would have increased by $334,000 (or
24%) for the seven months ended October 31, 1997, $826,000 (or 26%) for fiscal
1997, $707,000 (or 25%) for fiscal 1996 and $427,000 (or 16%) for fiscal 1995.
 
  Savings Incentive and Retirement Plus Plan for Domestic Employees
 
     The Coulter Corporation Savings Incentive and Retirement Plus Plan ("The
Plan") was established on March 31, 1996 by the Company as an amendment and
restatement of the Coulter Corporation Savings Incentive Plan established on
July 1, 1984. The Plan was created to provide various benefits through savings
and retirement contributions.
 
     The Plan meets the requirements of the Employee Retirement Income Security
Act of 1974 ("ERISA") and the Internal Revenue Code Sections 401(a), 401(k) and
501(a). The Plan is exempt from federal income taxation and has received a
favorable tax determination letter from the Internal Revenue Service.
 
     The Savings Incentive Segment ("SI Segment") of The Plan seeks to provide
retirement and other benefits for the employees, systematic savings, to
accumulate funds on a tax advantageous basis and to meet some of the larger
expenses incurred during their careers. The Company makes a matching
contribution equal to 100% of the first 1% of the savings contributions made by
the participant and 50% of the savings contribution from 2% to 6%. Savings
contributions in excess of 6% of annual compensation are not matched by the
Company. Participants' savings contributions and the Company's matching
contribution are paid to the SI

Segment on a monthly basis. For the seven months ended October 31, 1997 and for
the years ended March 31, 1997, 1996 and 1995, the Company's contributions to
the SI Segment of the Plan were $2,750,000, $4,801,000, $4,553,000 and
$4,511,000, respectively.
 
     The Retirement Plus Segment ("RP Segment") of the Plan is a defined
contribution plan designed to provide retirement, disability and death benefits
to employees. Participants may retire at normal retirement age (65) to receive
benefits and those who terminate after completing five years of employment are
fully vested in such benefits. Retirement benefits can be received at an earlier
age. The employer's contributions are based on the age and salary levels of
employees as defined in The Plan and are paid on a quarterly basis. Employees do
not contribute to the RP Segment of The Plan. For the seven months ended October
31, 1997 and for the year ended March 31, 1997, the Company contributed
$3,680,000 and $7,290,000, respectively, to the RP Segment of The Plan.
 
  Defined Benefit Plan for Domestic Employees
 
     On December 31, 1995 and March 31, 1996, the Company curtailed and
terminated, respectively, its defined benefit plan (Coulter Corporation Pension
Plan) for domestic employees. On January 1, 1996, the Coulter Corporation
Retirement Plus Plan ("Plus Plan") was established as a defined contribution
plan. The Plus Plan was funded by employees' rollover contributions from the
terminated plan as well as quarterly contributions paid by the Company. For the
three months ended March 31, 1996, the Company's contributions were $1,681,000.
 
     Effective March 31, 1996, the investment activity, administrative functions
and governmental reporting of the Plus Plan was combined with the Savings
Incentive Plan for improved effectiveness and efficiency.
 
     The termination of the defined benefit plan resulted in a gain of
$3,776,000 which was recorded as other income in the consolidated statement of
operations for the year ended March 31, 1996. At March 31, 1996, the unfunded
defined benefit obligation of $12,270,000 was included in accrued liabilities in
the consolidated balance sheets. Full and final payment of such obligation
occurred in June 1996.
 
     Domestic defined benefit pension costs recorded in the consolidated
statements of income for the years ended March 31, 1996 and 1995 included the
following components:

  Defined Benefit Plans for Foreign Employees
 
     The Company also sponsors noncontributory and contributory defined benefit
plans (the "Plans") covering certain foreign employees. The Plans call for
benefits to be paid to eligible employees at retirement based primarily upon
age, years of service and compensation rate. Disability and death benefits are
also available.
 
     The Company's funding policy is to contribute as required by income tax
laws. Contributions to the Plans reflect benefits attributed to employees'
services to date, as well as services expected to be earned in the future.
Assets of the Plans consist primarily of common and preferred stocks, investment
grade corporate bonds, government obligations and short-term money market
instruments.
 
     Net foreign pension costs recorded in the Company's consolidated statements
of income included the following components for the seven months ended October
31, 1997 and for the years ended March 31, 1997, 1996 and 1995:

     The current portion of deferred tax assets is included in prepaid expenses
and other current assets in the accompanying consolidated balance sheets. At
March 31, 1997, it includes $10,700,000 related to domestic operations and
$2,942,000 related to foreign operations (primarily operations in Japan). At
March 31, 1997, the non-current portion consists of a deferred tax asset of
$3,524,000, relating to operations in France and the U.S., which is included in
other assets, and a deferred tax liability of $4,114,000, which is reported as a
separate line item on the accompanying consolidated balance sheets.
 
     The Company has recognized its domestic current and non-current deferred
tax assets derived from temporary books/tax differences as it expects to
generate sufficient taxable income in the future to realize these benefits. Such
deferred tax assets have been calculated using regular tax rates with a
corresponding reduction, through the valuation allowance, to reflect the
deferred tax assets at the lower alternative minimum tax rate. Domestic deferred
tax assets derived from tax credit carryforwards in the amount of $900,000 are
included in prepaid expenses, as such credits are projected to be utilized next
year. Other Domestic deferred tax assets derived from tax credit carryforwards
have been fully reserved, however, through the valuation allowance, due to
uncertainties regarding the Company's ability to generate sufficient taxable
income in the U.S. and limitations on the recognition of certain credit
carryforwards under U.S. tax laws. The deferred tax assets relating to
operations in France and Japan have been recognized, as in the opinion of
management it is more likely than not that the foreign subsidiaries to which the
deferred assets relate will generate sufficient taxable income to realize such
deferred tax assets. The amount of the deferred tax asset considered realizable,
however, could be reduced in the near term if estimates of the future taxable
income necessary to realize such assets are reduced.

     On an Alternative Minimum Tax ("AMT") basis, the carryforwards are the same
as above, except for the foreign tax credit. The AMT foreign tax credit
carryforward is $2,300,000 expiring in 1998, $2,200,000 expiring in 1999,
$700,000 expiring in 2000, $2,400,000 expiring in 2001 and $1,463,000 expiring
in 2002. The minimum tax credit carryforward is $4,900,000 and may be carried
forward indefinitely.
 
     The difference between the reported tax provision and the provision
computed by applying the statutory U.S. federal income tax rate currently in
effect to income before income taxes for the seven months ended October 31, 1997
and for each of the three years ended March 31, 1997, is primarily due to the
effect of AMT, state and foreign income tax rates and the tax impact of the gain
on distribution of stock to shareholders of $5,332,000 for the seven months
ended October 31, 1997. Additionally, the Company recognized deferred tax
benefits related to changes in the valuation allowance of $2,300,000,
$4,500,000, $4,800,000 and $1,800,000 for the seven months ended October 31,
1997 and for the years ended March 31, 1997, 1996 and 1995, respectively.
 
     A provision has not been made for U.S. income taxes, or additional foreign
income taxes, on undistributed earnings of foreign subsidiaries. It is not
practicable to estimate the amount of additional tax that might be payable on
the foreign earnings, however, the Company believes that U.S. foreign tax
credits would largely eliminate any U.S. tax and offset any foreign tax on such
earnings.
 
     The Company's U.S. federal income tax returns for the years 1991 through
1993 are currently under review by the Internal Revenue Service ("IRS"). In the
opinion of management, the final result of the IRS's audit will not have a
material adverse effect on the Company's financial position or results of
operations.
 
     The Company's subsidiary in Brazil is contesting a tax assessment issued
several years ago, covering 1989 through 1991. At this time, it is not possible
to estimate the amount of any additional tax liability. However, in the opinion
of management, the ultimate liability will be substantially offset by available
net operating loss carryforwards and will not have a material impact on the
Company's financial position and results of operations.

  Legal Matters
 
     In January, 1996, the Company notified Hematronix, Inc. ("Hematronix"), a
competitive reagent manufacturer, that it believed Hematronix was selling
certain reagents and controls that infringed certain Company owned patents. In
response to these claims by the Company, Hematronix filed a complaint on April
15, 1996 in the United States District Court for the Eastern District of
California against the Company. The complaint seeks a declaratory judgment that
certain patents of the Company are invalid and thus not infringed. The complaint
also includes antitrust and related business tort claims regarding the Company's
sales and leasing activities. Currently at issue are four (4) United States
patents and the various antitrust claims raised by Hematronix. The Company has
counterclaimed that Hematronix has willfully infringed each of the patents at
issue. In addition, the Company has answered Hematronix's antitrust complaint
and denied violation of any of the antitrust laws or business tort claims set
forth by Hematronix in the complaint.
 
     A trial is set for 1998. The patent infringement matter will be tried first
and the antitrust issues will be tried in a separate trial. The Company's
management believes that it will prevail with regard to the infringement matters
in the patent actions, and that as a result of such finding the antitrust case
will not go forward. The Company is seeking a permanent injunction with regard
to the patents claimed to be infringed and reasonable royalties resulting from
such infringement.
 
     Certain other claims, suits and complaints in the ordinary course of
business have been filed or are pending against the Company. In the opinion of
management, all such matters are without merit or are of such kind and involve
such amounts that their resolution, net of related insurance coverage, would not
have a material effect on the consolidated financial position or results of
operations of the Company.
 
  Long Term Incentive Plan
 
     Effective April 1, 1995, the Company established a Long Term Performance
Plan (the "LTPP") to inspire and reinforce outstanding performance in selected
key employees whose efforts contribute substantially to the achievement of the
Company's long term goals and objectives. The LTPP provides for financial awards
to certain employees based on the Company's achievement of certain financial
objectives during the cumulative period from April 1, 1995 to March 31, 1998.
The Company has accrued $3,800,000 and $1,500,000 related to the LTPP as of
March 31, 1997 and 1996, respectively. These amounts are included in accrued
liabilities in the accompanying consolidated balance sheets.

         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
 1. REPORT BY MANAGEMENT
 
     The accompanying unaudited condensed financial statements of Coulter
Corporation and subsidiaries (the "Company") have been prepared by the Company
without audit pursuant to the rules and regulations of the Securities and
Exchange Commission. Certain information related to the Company's organization,
significant accounting policies and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted. These unaudited condensed financial
statements reflect, in the opinion of management, all adjustments (which include
only normal recurring adjustments) necessary to fairly state the financial
position and the results of operations for the periods presented and the
disclosures herein are adequate to make the information presented not
misleading. Operating results for the interim periods presented are not
indicative of the results that can be expected for a full year.
 
     The Company's latest fiscal year ended on March 31, 1997. The accompanying
unaudited condensed financial statements have been prepared in connection with a
proposed business combination with Beckman Instruments, Inc. ("Beckman") (see
Note 6) and reflect results for the six months ended September 30, 1997 and
1996.
 
 2. USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities, the
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of sales and expenses during the reporting
period. Actual results could differ from those estimates.
 
 3. INVENTORIES
 
     Inventories are comprised of the following (dollars in thousands):

 4. RESTRUCTURING CHARGES
 
     During the year ended March 31, 1997 the Company recorded restructuring
charges of $5,947,000. The objective of the charges was to reduce future costs
and improve operating results. The charge consisted primarily of severance and
retirement incentive pay; the cost of extended employees' benefits; and
consulting fees. The restructuring costs remaining to be paid at March 31, 1997
were $5,713,000 and are included in accrued liabilities in the March 31, 1997
condensed consolidated balance sheet. For the six-month period ended September
30, 1997, $4,853,000 was charged against this accrual. The Company believes the
balance of the accrued restructuring charges of $860,000 which is included in
accrued liabilities in the accompanying condensed consolidated balance sheet at
September 30, 1997 is adequate.

 5. COMMITMENTS AND CONTINGENCIES
 
  Legal Matters
 
     In January, 1996, the Company notified Hematronix, Inc. ("Hematronix"), a
competitive reagent manufacturer, that it believed Hematronix was selling
certain reagents and controls that infringe certain Coulter owned patents. In
response to these claims by the Company, Hematronix filed a complaint on April
15, 1996 in the United States District Court for the Eastern District of
California against the Company. The complaint seeks a declaratory judgment that
certain patents of the Company are invalid and thus not infringed. The complaint
also includes antitrust and related business tort claims regarding the Company's
sales and leasing activities. Currently at issue are four (4) United States
patents and the various antitrust claims raised by Hematronix. The Company has
counterclaimed that Hematronix has willfully infringed each of the patents at
issue. In addition, the Company has answered Hematronix's antitrust complaint
and denied violation of any of the antitrust laws or business tort claims set
forth by Hematronix in the complaint.
 
     A trial is set for 1998. The patent infringement matter will be tried first
and the antitrust issues will be tried in a separate trial. The Company's
management believes that it will prevail with regard to the infringement matters
in the patent actions, and that as a result of such finding the antitrust case
will not go forward. The Company is seeking a permanent injunction with regard
to the patents claimed to be infringed and reasonable royalties resulting from
such infringement.
 
     Certain other claims, suits and complaints in the ordinary course of
business have been filed or are pending against the Company. In the opinion of
management, all such matters are without merit or are of such kind and involve
such amounts that their resolution, net of related insurance coverage, would not
have a material effect on the consolidated financial position or results of
operations of the Company.
 
  Taxes
 
     A provision has not been made for U.S. income taxes, or additional foreign
income taxes, on undistributed earnings of foreign subsidiaries. It is not
practicable to estimate the amount of additional tax that might be payable on
the foreign earnings, however, the Company believes that U.S. foreign tax
credits would largely eliminate any U.S. tax and offset any foreign tax on such
earnings.
 
     The Company's subsidiary in Brazil is contesting a tax assessment issued
several years ago, covering 1989 through 1991. At this time, it is not possible
to estimate the amount of any additional tax liability. However, in the opinion
of management, the ultimate liability will be substantially offset by available
net operating loss carryforwards and will not have a material impact on the
Company's financial position and results of operations.
 
     The Company's U.S. federal income tax returns for the years 1991 through
1993 are currently under review by the Internal Revenue Service ("IRS"). In the
opinion of management, the final result of the IRS's audit will not have a
material adverse effect on the Company's financial position or results of
operations.
 
  Employment Agreements
 
     The Company maintains employment agreements (the "Employment Agreements")
with certain executives. These Employment Agreements provide for severance
payments in the event these executives are involuntarily terminated following a
change of control of the Company (as defined). The Employment Agreements have
terms which range from one to three years.

 6. PURCHASE AGREEMENT
 
     On August 29, 1997, the Company and its stockholders entered into a Stock
Purchase Agreement (the "Agreement") with Beckman Instruments, Inc. ("Beckman").
In connection with the Agreement, Beckman will acquire all of the Company's
shares in exchange for $875 million in cash and the assumption of liabilities.
Beckman, a Delaware corporation, provides systems, chemistries, software and
supplies, which automate and simplify biological analysis for use in life
science and clinical diagnostics laboratories. The merger is intended to be
accounted for under the purchase accounting method. Completion of the
transaction is subject to, among other things, regulatory approvals.
 
     In the event the Agreement receives all required approvals, the Company
anticipates incurring liabilities related to the accelerated achievement of
certain incentive plans and the granting of other discretionary bonus awards for
its U.S. and foreign employees. The Company estimates that it will incur a total
liability of approximately $100 million related to these programs.
 
 7. SUBSEQUENT EVENTS
 
     On October 20, 1997, the Board of Directors agreed to distribute as a
dividend all of the Company's shares of Coulter Pharmaceuticals, Inc. and 4.9
million shares of Coulter Cellular Therapies, Inc. to the respective
shareholders of record as of October 30, 1997. This distribution was completed
on November 14, 1997. In connection with this transaction, the Company expects
to incur a tax liability of $5 million.
