LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) 1. BASIS OF FINANCIAL STATEMENT PRESENTATION The condensed consolidated financial statements include the accounts of Laboratory Corporation of America Holdings and its wholly owned subsidiaries (the "Company") after elimination of all material intercompany accounts and transactions. On January 17, 2003, the Company completed the acquisition of DIANON Systems, Inc., (DIANON) a leading U.S. provider of anatomic pathology and oncology testing services. Disclosure of certain business combination transactions is included in Note 7 - Business Acquisition - DIANON Systems, Inc. The Company operates in one business segment. The financial statements of the Company's foreign subsidiaries are measured using the local currency as the functional currency. Assets and liabilities are translated at exchange rates as of the balance sheet date. Revenues and expenses are translated at average monthly exchange rates prevailing during the period. Resulting translation adjustments are included in "Accumulated Other Comprehensive Earnings (Loss)." The accompanying condensed consolidated financial statements of the Company are unaudited. In the opinion of management, all adjustments (which include only normal recurring accruals) necessary for a fair presentation of such financial statements have been included. Interim results are not necessarily indicative of results for a full year. The financial statements and notes are presented in accordance with the rules and regulations of the Securities and Exchange Commission and do not contain certain information included in the Company's 2002 annual report on Form 10-K. Therefore, the interim statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company's annual report. Certain amounts in the prior year's financial statements have been reclassified to conform with the current year presentation. 2. EARNINGS PER SHARE Basic earnings per share is computed by dividing net earnings by the weighted average number of common shares outstanding. Dilutive earnings per share is computed by dividing net earnings by the weighted average number of common shares outstanding plus potentially dilutive shares, as if they had been issued at the beginning of the period presented. Potentially dilutive common shares result primarily from the Company's restricted stock awards and outstanding stock options.

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) The following represents a reconciliation of the weighted average shares used in the calculation of basic and diluted earnings per share: Three Months Nine Months Ended September 30, Ended September 30, ------------------------- ------------------------ 2003 2002 2003 2002 ------------------------- ------------------------ Basic 143,459,010 144,527,602 144,628,024 141,746,566 Assumed conversion/ exercise of: Stock options 495,472 440,606 413,218 781,974 Restricted stock awards 412,503 757,907 360,271 1,165,568 ----------- ----------- ----------- ----------- Diluted 144,366,985 145,726,115 145,401,513 143,694,108 ----------- ----------- ----------- ----------- The following table summarizes the potential common shares not included in the computation of diluted earnings per share because their impact would have been antidilutive: September 30, 2003 2002 ------------------------ Stock Options 4,328,634 1,428,379 The Company's zero coupon-subordinated notes are contingently convertible into 9,977,634 shares of common stock and are not currently included in the diluted earnings per share calculation because these notes were not convertible according to their terms during the period ended September 30, 2003. 3. STOCK COMPENSATION PLANS During July 2003, in connection with naming a new director to the Company's Board of Directors, the Company made a pro-rated restricted stock award of 1,329 shares and a pro-rated stock option award of 2,046 options at a price of $31.35 under its 2000 Stock Incentive Plan. During May 2003, the Company made awards of 8,230 shares of restricted stock, and 12,680 options to its non-employee directors at a price of $30.36, under its 2000 Stock Incentive Plan. During February 2003, the Company granted to employees 1,532,500 options at a price of $24.46 under its 2000 Stock Incentive Plan. During March 2003, the Company granted to employees 216,700 options at a price of $28.18 under its 2000 Stock Incentive Plan. In accordance with the terms of the Company's stock incentive plan, which permits employees to meet tax withholding requirements upon the vesting of restricted shares by surrendering vested shares equal in value to the tax obligation, certain employees of the Company surrendered 174,794 shares of stock totaling approximately $4.9 in April 2003 to satisfy their payroll tax obligations in connection with the vesting of restricted shares.

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) The tax benefits associated with the exercise of non-qualified stock options reduced taxes currently payable by $4.2 and $15.9 for the nine months ended September 30, 2003 and 2002, respectively. Such benefits are credited to additional paid-in-capital. On January 21, 2003, in connection with the acquisition of DIANON, the Company filed a Form S-8 registering approximately 690,000 shares of the Company's common stock under DIANON stock incentive plans. The Company applies the provisions of APB Opinion No. 25 in accounting for its stock option plans and, accordingly, no compensation cost has been recognized in the financial statements. Had the Company determined compensation cost based on the fair value method as defined in SFAS No. 123, and as amended by SFAS No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure - - an amendment of FASB Statement No. 123", the impact on the Company's net earnings on a pro forma basis is indicated below: Three Months Ended Nine Months Ended September 30, September 30, -------------------- -------------------- 2003 2002 2003 2002 -------------------- -------------------- Net earnings As reported $ 83.1 $ 57.3 $ 243.4 $ 201.6 Pro forma $ 76.5 52.2 223.8 186.1 Basic earnings per common share As reported 0.58 0.40 1.68 1.42 Pro forma 0.53 0.36 1.55 1.31 Diluted earnings per common share As reported 0.58 0.39 1.67 1.40 Pro forma 0.53 0.36 1.54 1.30 4. STOCK REPURCHASE PROGRAM On October 22, 2002, the Company's Board of Directors authorized a stock repurchase program under which the Company could purchase up to an aggregate of $150.0 of its common stock from time- to-time. During the nine months ended September 30, 2003, the Company completed this program, purchasing approximately 5.2 million shares of its common stock totaling approximately $150.0 with cash flow from operations. 5. SENIOR CREDIT FACILITIES On January 14, 2003, the Company entered into a new $150.0 364- day revolving credit facility with Credit Suisse First Boston, acting as Administrative Agent, and a group of financial institutions to replace the existing $100.0 364-day revolving credit facility. The $200.0 three-year revolving credit facility was amended on January 14, 2003 and expires on February 18, 2005. These credit facilities bear interest at varying rates based upon the Company's credit rating with Standard & Poor's Ratings Services. As of September 30, 2003, the effective interest rate on the revolving credit agreements was 1.95%.

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) On January 17, 2003, in conjunction with the acquisition of DIANON, the Company borrowed $350.0 under the DIANON Bridge Loan Agreement with Credit Suisse First Boston, acting as Administrative Agent. On January 31, 2003, the Company sold $350.0 aggregate principal amount of its 5 1/2% Senior Notes due February 1, 2013. Proceeds from the issuance of these Notes ($345.1) together with cash on hand were used to repay the $350.0 principal amount of the Company's bridge loan facility, and as a result, the DIANON bridge loan was terminated. During the nine months ended September 30, 2003, the Company borrowed a total of $265.0 and made payments of $240.0 under its revolving credit agreements leaving an outstanding balance of $25.0 as of September 30, 2003. 6. DERIVATIVE FINANCIAL INSTRUMENTS Interest rate swap agreements, which have been used by the Company from time to time in the management of interest rate exposure, are accounted for on an accrual basis. Amounts to be paid or received under such agreements are recognized as interest expense in the periods in which they accrue. On June 18, 2003, the Company terminated its only outstanding interest rate swap agreement and received net proceeds of $5.3. Approximately $1.2 of these proceeds has been amortized and is recorded in interest expense for the nine months ended September 30, 2003. The remaining $4.1 of these proceeds has been deferred on the Company's balance sheet and will reduce interest expense on the 5 1/2% senior notes over the life of the notes. Including the effect of this swap agreement, the weighted-average effective interest rate on the Company's 5 1/2% senior notes was 5.38% at September 30, 2003. The Company's zero coupon-subordinated notes contain the following three features that are considered to be embedded derivative instruments under FAS No. 133: 1) The Company will pay contingent cash interest on the zero coupon subordinated notes after September 11, 2006, if the average market price of the notes equals 120% or more of the sum of the issue price, accrued original issue discount and contingent additional principal, if any, for a specified measurement period. 2) Contingent additional principal will accrue on the zero coupon-subordinated notes during the two-year period from September 11, 2004 to September 11, 2006, if the Company's stock price is at or below specified thresholds. 3) Holders may surrender zero coupon-subordinated notes for conversion during any period in which the rating assigned to the zero coupon-subordinated notes by Standard & Poor's Ratings Services is BB- or lower.

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) Based upon independent appraisals, these embedded derivatives had no fair value at September 30, 2003 and 2002. 7. BUSINESS ACQUISITION - DIANON SYSTEMS, INC. On January 17, 2003, the Company completed the acquisition of all of the outstanding shares of DIANON Systems, Inc. (DIANON) for $47.50 per share in cash, or approximately $595.6 including transaction fees and expenses, and converted approximately 390,000 vested DIANON employee stock options into approximately 690,000 vested Company options valued at $8.5. The transaction total of approximately $604.5 was funded by a combination of cash on hand, borrowings under the Company's senior credit facilities and a bridge loan facility. DIANON is a leading provider of anatomic pathology and oncology testing services in the U.S. and had 2001 revenues of approximately $125.7. DIANON had approximately 1,100 employees at the closing date of the acquisition and processed more than 8,000 samples per day in one main testing facility and four regional labs. The acquisition of DIANON was accounted for under the purchase method of accounting. As such, the cost to acquire DIANON has been allocated to the assets and liabilities acquired based on estimated fair values as of the closing date. The consolidated financial statements include the results of operations of DIANON subsequent to the closing of the acquisition. The Company finalized its recording of the DIANON purchase price allocation during the second quarter of 2003. In connection with the DIANON integration plan, the Company recorded $20.8 of costs associated with the execution of the plan. The majority of these integration costs related to contractual obligations associated with leased facilities and equipment ($12.7) and employee severance ($8.1). These costs were accounted for as costs of the DIANON acquisition and included in goodwill. The following table summarizes the Company's purchase price allocation related to the acquisition of DIANON based on the fair value of the assets acquired and liabilities assumed on the acquisition date.

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) As a result of this acquisition, the Company recorded an addition to non-deductible goodwill of approximately $355.5, an addition to customer lists of approximately $227.8 (expected period of benefit of 30 years, non-deductible for tax) and an addition to trade names of approximately $43.7 (expected period of benefit of 15 years, non-deductible for tax).

Amortization expense for the net carrying amount of intangible assets is estimated to be $10.0 for the remainder of fiscal 2003, $40.8 in fiscal 2004, $40.1 in fiscal 2005, $38.6 in fiscal 2006, and $37.1 in fiscal 2007. 10. NEW ACCOUNTING PRONOUNCEMENTS In May 2003, the Statement of Financial Accounting Standards ("SFAS") No. 150, "Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity" was issued. SFAS No. 150 requires certain financial instruments that embody obligations of the issuer and have characteristics of both liabilities and equity to be classified as liabilities.

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) The provisions for SFAS No. 150 are effective for financial instruments entered into or modified after May 31, 2003 and generally to all other instruments that exist as of the beginning of the first interim financial reporting period beginning after June 15, 2003. The Company does not have any financial instruments that meet the provisions of SFAS No. 150, and therefore, the provisions of this Statement do not have a material impact on the Company's consolidated financial position, results of operations or cash flows. In April 2003, the Statement of Financial Accounting Standards ("SFAS") No. 149, "Amendment of Statement 133 on Derivative Instruments and Hedging Activities" was issued. This Statement amends and clarifies accounting for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities under SFAS No. 133. The new guidance amends SFAS No. 133 for decisions made (1) as part of the Derivatives Implementation Group process that effectively required amendments to SFAS No. 133, (2) in connection with other Board projects dealing with financial instruments, and (3) in connection with implementation issues raised in relation to the application of the definition of a derivative. The amendments set forth in SFAS No. 149 improve financial reporting by requiring that contracts with comparable characteristics be accounted for similarly. This Statement is generally effective for contracts entered into or modified after June 30, 2003 and for hedging relationships designated after June 30, 2003. The Company has not entered into or modified any derivative contracts during the third quarter of 2003. It is not expected that the provisions of SFAS No. 149 will have a material impact on the Company's consolidated financial position, results of operations or cash flows. In January 2003, the FASB issued FASB Interpretation No. 46 (FIN No. 46), "Consolidation of Variable Interest Entities, an Interpretation of ARB No. 51." FIN No. 46 requires certain variable interest entities to be consolidated by the primary beneficiary of the entity if the equity investors in the entity do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. FIN No. 46 is effective immediately for all new variable interest entities created or acquired after January 31, 2003. For variable interest entities created or acquired prior to February 1, 2003, the provisions of FIN No. 46 must be applied for the first period ending after December 15, 2003. The Company does not believe it has any unconsolidated variable interest entities, but has not fully completed its evaluation. In December 2002, Statement of Financial Accounting Standards ("SFAS") No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure - an amendment of FASB Statement No. 123",

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) was issued. This Statement amends SFAS No. 123 to provide alternative methods of transition for a voluntary change to the fair-value based method of accounting for stock-based employee compensation. In addition, SFAS No. 148 amends the disclosure requirements of SFAS No. 123 to require disclosure in interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. The Company does not intend to adopt the fair-value method of accounting for stock-based employee compensation under SFAS No. 123 and therefore, the adoption of SFAS No. 148 has only impacted disclosures, and not the financial results of the Company. In November 2002, the FASB issued Interpretation No. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others." Interpretation No. 45 changes current practice in accounting for and disclosure of guarantees and will require certain guarantees to be recorded as liabilities at fair value on the balance sheet. Prior practice required that liabilities related to guarantees be recorded only when a loss was probable and reasonably estimable, as those terms are defined in SFAS No. 5, "Accounting for Contingencies." Interpretation No. 45 also requires a guarantor to make significant new disclosures, even when the likelihood of making any payments under the guarantee is remote. The disclosure requirements of Interpretation No. 45 were effective December 31, 2002. The initial recognition and measurement provisions are applicable on a prospective basis to guarantees issued or modified after December 31, 2002. The Company does not have any material guarantees that would require current disclosure or further recognition under Interpretation No. 45. 11. COMMITMENTS AND CONTINGENCIES The Company is involved in litigation purporting to be a nation-wide class action involving the alleged overbilling of patients who are covered by private insurance. The Company has reached a settlement with the class that will not materially differ from accruals previously established or have a material adverse effect on the Company. The Company has now substantially implemented its obligations under the settlement. On January 9, 2001, the Company was served with a complaint in North Carolina which purported to be a class action and made claims similar to those referred to above. That claim has now been dismissed with prejudice. On June 24, 2003, the Company and certain of its executive officers were sued in the United States District Court for the Middle District of North Carolina in the first of a series of putative shareholder class actions alleging securities fraud. Since that date, at least five other complaints containing substantially identical allegations have been filed against the Company and certain of the Company's executive officers. Each of the complaints alleges that the defendants violated the federal securities laws by making material misstatements and/or omissions that caused the price

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) of the Company's stock to be artificially inflated between February 13 and October 3, 2002. The plaintiffs seek certification of a class of substantially all persons who purchased shares of the Company's stock during that time period and unspecified monetary damages. These six cases have been consolidated and will proceed as a single case. The defendants deny any liability and intend to defend the case vigorously. At this time, it is premature to make any assessment of the potential outcome of the cases or whether they could have a material adverse effect on the Company's financial condition. The Company is the appellant in a patent case originally filed in the United States District Court for the District of Colorado. The Company has disputed liability and contested the case vigorously. After a jury trial, the district court entered judgment against the Company for patent infringement. The Company appealed the case to the United States Court of Appeals for the Federal Circuit. The Company has received a letter from its counsel dated February 7, 2003 stating "it remains our opinion that the amended judgment and order will be reversed on appeal." The Company is a party to two lawsuits involving Chiron Inc. relating to Hepatitis C and HIV testing. Chiron asserts that the Company has infringed on Chiron's patents in each of these areas. The Company denies liability and intends to contest the suits vigorously. It is premature at this juncture to assess the likely outcome of these matters, or to determine whether they will have a material effect on the Company. The Company is also involved in various claims and legal actions arising in the ordinary course of business. These matters include, but are not limited to, intellectual property disputes, professional liability, employee related matters, and inquiries from governmental agencies and Medicare or Medicaid payors and managed care payors requesting comment on allegations of billing irregularities that are brought to their attention through billing audits or third parties. In the opinion of management, based upon the advice of counsel and consideration of all facts available at this time, the ultimate disposition of these matters is not expected to have a material adverse effect on the financial position, results of operations or liquidity of the Company. The Company is also named from time to time in suits brought under the qui tam provisions of the False Claims Act. These suits typically allege that the Company has made false statements and/or certifications in connection with claims for payment from federal health care programs. They may remain under seal (hence, unknown to the Company) for some time while the government decides whether to intervene on behalf of the qui tam plaintiff. Such claims are an inevitable part of doing business in the health care field today and, in the opinion of management, based upon the advice of counsel and consideration of all facts available at this time, the ultimate disposition of those qui tam matters presently known to the Company is not expected to have a material adverse effect on the financial position, results of operations or liquidity of the Company.

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) The Company believes that it is in compliance in all material respects with all statutes, regulations and other requirements applicable to its clinical laboratory operations. The clinical laboratory testing industry is, however, subject to extensive regulation, and many of these statutes and regulations have not been interpreted by the courts. There can be no assurance therefore that applicable statutes and regulations might not be interpreted or applied by a prosecutorial, regulatory or judicial authority in a manner that would adversely affect the Company. Potential sanctions for violation of these statutes and regulations include significant fines and the loss of various licenses, certificates and authorizations. Under the Company's present insurance programs, coverage is obtained for catastrophic exposures as well as those risks required to be insured by law or contract. The Company is responsible for the uninsured portion of losses related primarily to general, professional and vehicle liability, certain medical costs and workers' compensation. The self-insured retentions are on a per occurrence basis without any aggregate annual limit. Provisions for losses expected under these programs are recorded based upon the Company's estimates of the aggregated liability of claims incurred. At September 30, 2003 and 2002, the Company had provided letters of credit aggregating approximately $45.2 and $36.6 respectively, primarily in connection with certain insurance programs.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS FORWARD-LOOKING STATEMENTS The Company has made in this report, and from time to time may otherwise make in its public filings, press releases and discussions with Company management, forward-looking statements concerning the Company's operations, performance and financial condition, as well as its strategic objectives. Some of these forward-looking statements can be identified by the use of forward-looking words such as "believes", "expects", "may", "will", "should", "seeks", "approximately", "intends", "plans", "estimates", or "anticipates" or the negative of those words or other comparable terminology. Such forward-looking statements are subject to various risks and uncertainties and the Company claims the protection afforded by the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. One should understand that it is not possible to predict or identify all such factors. Consequently, the reader should not consider any such list to be a complete statement of all potential risks or uncertainties. Actual results could differ materially from those currently anticipated due to a number of factors in addition to those discussed elsewhere herein and in the Company's other public filings, press releases and discussions with Company management, including: 1. changes in federal, state, local and third party payor regulations or policies (or in the interpretation of current regulations) affecting governmental and third-party reimbursement for clinical laboratory testing, including for example, current proposals to require Medicare beneficiaries to pay a co-payment for laboratory services and to require that Medicare providers bill Medicare no more than 120% of the average amount they receive as payment from other payors; 2. adverse results from investigations of clinical laboratories by the government, which may include significant monetary damages and/or exclusion from the Medicare and Medicaid programs; 3. loss or suspension of a license or imposition of a fine or penalties under, or future changes in, the law or regulations of the Clinical Laboratory Improvement Act of 1967, and the Clinical Laboratory Improvement Amendments of 1988, or those of Medicare, Medicaid or other federal, state or local agencies; 4. failure to comply with applicable Federal Occupational Safety and Health Administration requirements and the Needlestick Safety and Prevention Act which may result in penalties and loss of licensure;

5. failure to comply with HIPAA, which could result in significant fines; 6. failure of third party payors to complete testing with the Company, or to accept or remit transactions in HIPAA-required standard transaction and code set format, could result in an interruption in the Company's cash flow; 7. increased competition, including price competition; 8. changes in payor mix, including an increase in capitated managed-cost health care; 9.failure to obtain and retain new customers and alliance partners, or a reduction in tests ordered or specimens submitted by existing customers; 10.failure to integrate newly acquired businesses and the cost related to such integration; 11.adverse results in litigation matters; 12.inability to attract and retain experienced and qualified personnel; 13.failure to maintain the Company's days sales outstanding levels; 14.decrease in credit ratings by Standard & Poor's and/or Moody's; 15.failure to develop or acquire licenses for new or improved technologies, or if customers use new technologies to perform their own tests; 16.inability to commercialize newly licensed tests or technologies or to obtain appropriate reimbursements for such tests; 17.inability to obtain and maintain adequate patent and other proprietary rights protection of our products and services and successfully enforce our proprietary rights; 18.the scope, validity and enforceability of patents and other proprietary rights held by third parties which might impact on our ability to develop, perform, or market our tests or operate our business; and 19.failure in the Company's information technology systems resulting in an increase in testing turnaround time or billing processes.

RESULTS OF OPERATIONS - -------------------- As discussed in the Company's Annual Report for the year ended December 31, 2002, the Company acquired Dynacare Inc. on July 25, 2002 and DIANON Systems, Inc. on January 17, 2003. All dollar amounts are in millions. Three Months ended September 30, 2003 compared with Three Months ended September 30, 2002. Net sales for the three months ended September 30, 2003 were $752.0, an increase of $96.8, or approximately 14.8%, from $655.2 for the comparable 2002 period. The sales increase is a result of an increase of approximately 9.3% in volume and 5.5% in price. Volume growth was affected by the acquisitions of DIANON and Dynacare as well as growth in the Company's esoteric test volumes (including human papillomavirus (HPV) and cystic fibrosis). The growth in price was affected by this same shift in test mix and from shifts in histology testing which is primarily DIANON- related. Cost of sales, which includes primarily laboratory and distribution costs, was $441.1 for the three months ended September 30, 2003 compared to $381.9 in the corresponding 2002 period, an increase of $59.2. The increase in cost of sales is primarily the result of increases in volume and supplies due to recent acquisitions, growth in the base business and growth in esoteric and genomic testing (with significant increases in cystic fibrosis and HPV testing). Cost of sales as a percentage of net sales was 58.7% for the three months ended September 30, 2003 and 58.3% in the corresponding 2002 period. Selling, general and administrative expenses increased to $162.7 for the three months ended September 30, 2003 from $153.4 in the same period in 2002. This increase resulted primarily from personnel and other costs as a result of the Dynacare and DIANON acquisitions. As a percentage of net sales, selling, general and administrative expenses were 21.6% and 23.4% for the three months ended September 30, 2003 and 2002, respectively, reflecting the realization of synergies from the Dynacare and DIANON acquisitions, as well as the Company's reduction of its bad debt expense (as a percentage of net sales) rate by approximately 50 basis points during the quarter. The amortization of intangibles and other assets was $9.5 and $6.2 for the three months ended September 30, 2003 and 2002. The increase in the amortization expense for the three months ended September 30, 2003 is primarily the result of the acquisition of DIANON. Interest expense was $9.5 for the three months ended September 30, 2003 compared with $5.3 for the same period in 2002. This increase was a direct result of the Company's financing of the DIANON acquisition. Income from equity investments was $11.5 for the three months ended September 30, 2003. This income represents the Company's ownership share in equity affiliates acquired as part of the Dynacare acquisition on July 25, 2002. A significant portion of this income is derived from investments in Ontario and Alberta,

Canada, and is earned in Canadian dollars. The strengthening of the Canadian dollar versus the U.S. dollar during the third quarter of 2003 has had a positive impact on this income as well as the cash generated from the Canadian investments. The provision for income taxes as a percentage of earnings before taxes was approximately 39.5% for the three months ended September 30, 2003 compared to 41.5% for the three months ended September 30, 2002. The decrease in the effective tax rate for the three months ended September 30, 2003 is due to a $2.1 state tax recovery during the third quarter of 2003. Nine Months ended September 30, 2003 compared with Nine Months ended September 30, 2002. Net sales for the nine months ended September 30, 2003 were $2,207.9, an increase of $350.3, or 18.9%, from $1,857.6 for the same period in 2002. The sales increase is a result of an increase of approximately 13.2% in volume and 5.7% in price. Volume growth was affected by the acquisitions of Dynacare and DIANON as well as growth in the Company's esoteric test volumes (including HPV and cystic fibrosis). The growth in price was affected by this same shift in test mix and from shifts in histology testing which is primarily DIANON-related. These improvements were partially offset by the impact of severe winter weather during the first quarter of 2003 and physician strikes to protest rising malpractice insurance rates during the second quarter. Cost of sales, which includes primarily laboratory and distribution costs, was $1,284.0 for the nine months ended September 30, 2003 compared to $1,049.7 for the same period of 2002, an increase of $234.3. The increase in cost of sales is primarily the result of increases in volume and supplies due to recent acquisitions, growth in the base business and growth in esoteric and genomic testing (with significant increases in cystic fibrosis and HPV testing). Cost of sales as a percentage of net sales was 58.2% for the nine months ended September 30, 2003 and 56.5% for the same period in 2002, reflecting cost of additional lab infrastructure along with the shift in test mix. Selling, general and administrative expenses increased to $490.1 for the nine months ended September 30, 2003 from $427.3 for the same period in 2002. This increase resulted primarily from personnel and other costs as a result of the recent acquisitions. As a percentage of net sales, selling, general and administrative expenses were 22.2% and 23.0% for the nine months ended September 30, 2003 and 2002, respectively, reflecting the realization of synergies from the Dynacare and DIANON acquisitions, as well as the Company's reduction of its bad debt expense rate by over 150 basis points during the first nine months of 2003 compared to 2002. The amortization of intangibles and other assets was $27.5 and $16.4 for the nine months ended September 30, 2003 and 2002. The increase in the amortization expense for the nine months ended September 30, 2003 is a result of the acquisitions of Dynacare and DIANON.

Interest expense was $30.9 for the nine months ended September 30, 2003 compared with $13.7 for the same period in 2002. This increase was a direct result of the Company's financing of the DIANON acquisition. Income from equity investments was $32.6 for the nine months ended September 30, 2003. This income represents the Company's ownership share in equity affiliates acquired as part of the Dynacare acquisition on July 25, 2002. A significant portion of this income is derived from investments in Ontario and Alberta, Canada, and is earned in Canadian dollars. The strengthening of the Canadian dollar versus the U.S. dollar during the nine months ended September 30, 2003 has had a positive impact on this income as well as the cash generated from the Canadian investments. The provision for income taxes as a percentage of earnings before taxes was 40.5% for the nine months ended September 30, 2003 compared to 41.0% for the nine months ended September 30, 2002. The decrease in the effective tax rate for the nine months ended September 30, 2003 is due to a $2.1 state tax recovery during the third quarter of 2003. LIQUIDITY AND CAPITAL RESOURCES - ------------------------------- Net cash provided by operating activities was $420.1 and $326.4 for the nine months ended September 30, 2003 and September 30, 2002, respectively. The increase in cash flows from operations primarily resulted from improved earnings and the improvement of the Company's DSO to 53 days at September 30, 2003 from 56 days at September 30, 2002. Capital expenditures were $60.4 and $54.9 at September 30, 2003 and 2002, respectively. The Company expects capital expenditures of approximately $90.0 in 2003. These expenditures are intended to continue to standardize lab and billing information systems and further automate laboratory processes with the investment in state- of-the-art hematology analyzers. Such expenditures are expected to be funded by cash flow from operations as well as borrowings under the Company's revolving credit facilities. During the three months ended September 30, 2003, the Company repaid a total of $60.0 on its revolving credit facilities. During the three months ended September 30, 2003, the Company purchased approximately 2.1 million shares of its common stock totaling approximately $63.7 with cash flow from operations for a total repurchase of approximately 5.3 million shares totaling approximately $150.0 for the nine month period. In addition, certain employees of the Company surrendered 174,794 shares of restricted stock in April 2003 for the payment of payroll taxes totaling approximately $4.9, in accordance with the terms of the Company's stock incentive plan. The Company plans to announce a new share repurchase program during the fourth quarter of 2003. It is the Company's intention to fund future purchases of its common stock with cash flow from operations.

In connection with the DIANON integration plan, the Company expects to achieve synergy savings of approximately $7.5 in 2003, $25.0 in 2004, and a total savings of $35.0 by 2005. The integration of Dynacare remains on schedule with $4.0 in synergy savings at the end of 2002, $36.0 in 2003, and a total savings of $45.0 by 2004. During the first quarter of 2003, the Company entered into an interest rate swap agreement with a major financial institution, solely to manage its interest rate exposure on $175.0 of its 5 1/2% senior notes. This swap agreement was terminated during June 2003 and resulted in net proceeds to the Company of $5.3. Based on current and projected levels of operations, coupled with availability under its revolving credit facilities, the Company believes it has sufficient liquidity to meet both its short-term and long-term cash needs.

The Company may choose to pay the purchase price in cash or common stock or a combination of cash and common stock. If the holders elect to require the Company to purchase their notes, it is the Company's current intention to retire the notes by a cash payment. Future market conditions may be different from those affecting the Company today. Should the holders put the notes to the Company on any of the dates above, the Company believes that it will be able to obtain alternate financing to satisfy this obligation. ITEM 3. Quantitative and Qualitative Disclosure about Market Risk The Company addresses its exposure to market risks, principally the market risk associated with changes in interest rates, through a controlled program of risk management that has included in the past, the use of derivative financial instruments such as interest rate swap agreements. As more fully discussed in Note 6 to the Unaudited Condensed Consolidated Financial Statements, the Company had an

interest rate swap agreement with a major financial institution, solely to manage its interest rate exposure on $175.0 of its 5 1/2% senior notes. This swap agreement was terminated during June 2003 and the Company received net proceeds of $5.3. Although, as set forth below, the Company's zero coupon-subordinated notes contain features that are considered to be embedded derivative instruments, the Company does not hold or issue derivative financial instruments for trading purposes. The Company does not believe that its exposure to market risk is material to the Company's financial position or results of operations. The Company's zero coupon-subordinated notes contain the following three features that are considered to be embedded derivative instruments under FAS No. 133: 1) The Company will pay contingent cash interest on the zero coupon-subordinated notes after September 11, 2006, if the average market price of the notes equals 120% or more of the sum of the issue price, accrued original issue discount and contingent additional principal, if any, for a specified measurement period. 2) Contingent additional principal will accrue on the zero coupon-subordinated notes during the two-year period from September 11, 2004 to September 11, 2006, if the Company's stock price is at or below specified thresholds. 3) Holders may surrender zero coupon-subordinated notes for conversion during any period in which the rating assigned to the zero coupon-subordinated notes by Standard & Poor's Ratings Services is BB- or lower. Based upon independent appraisals, these embedded derivatives had no fair value at September 30, 2003.

ITEM 4. Controls and Procedures As of the end of the period covered by this Form 10-Q, the Company carried out, under the supervision and with the participation of the Company's management, including the Company's Chief Executive Officer and Chief Financial Officer, an evaluation of the effectiveness of the design and operation of the Company's disclosure controls and procedures. Based on the foregoing, the Company's Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures are effective in timely alerting them to material information which is required to be included in the periodic reports that the Company must file with the Securities and Exchange Commission. There were no significant changes in the Company's internal controls or in other factors that could adversely affect the internal controls subsequent to the date the Company completed its evaluation.
