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. 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 2003 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. 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 Six Months Ended June 30, Ended June 30, ------------------------ ---------------------- 2004 2003 2004 2003 ------------------------ ------------------------ Basic 140,053,538 144,562,713 140,923,330 145,222,214 Assumed conversion/ exercise of: Stock options 775,912 485,967 803,187 381,169 Restricted stock awards 444,263 -- 609,980 103,769 ----------- ----------- ----------- ----------- Diluted 141,273,713 145,048,680 142,336,497 145,707,152 =========== =========== =========== =========== 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: June 30, 2004 2003 ---------------------- Stock Options 1,492,611 4,432,902 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 at June 30, 2004. Holders of the zero coupon- subordinated notes may require the Company to purchase all or a portion of their notes on September 11, 2004, 2006 and 2011 at prices ranging from $712.97 to $819.54 per note. 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. However, future market conditions are subject to change. Should the holders put the notes to the Company on any of the dates above, the Company believes that it will be able to satisfy this contingent obligation with cash on hand, borrowings on the revolving credit facility, and additional financing if necessary. 3. STOCK COMPENSATION PLANS During February 2004, the Company granted 1,738,800 options at a price of $39.00 under its 2000 Stock Incentive Plan. During March 2004, the Company recorded aggregate awards of 11,329 shares of restricted stock at a weighted average price of $35.29 to one of the principals in the Company's research and development joint venture and a non-employee director under its 2000 Stock Incentive Plan.

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) During May 2004, the Company made awards of 7,728 shares of restricted stock and 11,904 options to its non-employee directors at a price of $38.80 under its 2000 Stock Incentive Plan. The tax benefits associated with the exercise of non-qualified stock options reduced taxes currently payable by $5.7 and $2.7 for the six months ended June 30, 2004 and 2003, respectively. Such benefits are credited to additional paid-in-capital. The Company applies the provisions of APB Opinion No. 25 in accounting for its employee stock option and stock purchase plans and, accordingly, no compensation cost has been recognized for these plans in the financial statements. Had the Company determined compensation cost for these two plans based on the fair value method as defined in SFAS No. 123, the impact on the Company's net earnings on a pro forma basis is indicated below: Three Months Ended Six Months Ended June 30, June 30, ------------------ ---------------- 2004 2003 2004 2003 ------------------ ---------------- Net earnings, as reported $ 98.3 $ 86.4 $185.6 $160.3 Add: Restricted stock-based compensation Under APB 25 3.0 4.1 9.5 8.6 Deduct: Total stock-based compensation expense determined under the fair value method for all awards, net of related tax effects (9.1) (10.7) (21.7) (21.7) ----- ----- ----- ----- Pro forma net income $ 92.2 $ 79.8 $173.4 $147.2 ===== ===== ===== ===== Basic earnings per common share As reported 0.70 0.60 1.32 1.10 Pro forma 0.66 0.55 1.23 1.01 Diluted earnings per common share As reported 0.70 0.60 1.30 1.10 Pro forma 0.65 0.55 1.22 1.01 4. STOCK REPURCHASE PROGRAM On December 17, 2003, the Company's Board of Directors authorized a stock repurchase program under which the Company may purchase up to an aggregate of $250.0 of its common stock from time- to-time, beginning in the first quarter of 2004. During the first six months of 2004, the Company purchased approximately 4.6 million shares of its common stock totaling $182.1 with cash flow from operations. It is the Company's intention to fund future purchases of its common stock with cash flow from operations. 5. SENIOR CREDIT FACILITIES On January 13, 2004, 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 $150.0 364-day revolving credit facility, which had terminated. The $200.0 three-year revolving

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) 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. There were no balances outstanding on the Company's senior credit facilities at June 30, 2004. The senior credit facilities are available for general corporate purposes, including working capital, capital expenditures, funding of share repurchases and other payments, and acquisitions. The agreements contain certain debt covenants which require that the Company maintain leverage and interest coverage ratios of 2.5 to 1.0 and 5.0 to 1.0, respectively. Both ratios are calculated in relation to EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization). The covenants also limit the payment of dividends. The Company is in compliance with all covenants at June 30, 2004. 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 at fair value. Amounts to be paid or received under such agreements are recognized as interest income or expense in the periods in which they accrue. The Company's zero coupon-subordinated notes contain the following three features that are considered to be embedded derivative instruments under Statement of Financial Accounting Standards ("SFAS") No. 133 "Accounting for Derivative Instruments and Hedging Activities": 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 market value at June 30, 2004 and 2003. 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

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) 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. The following unaudited pro forma combined financial information for the six months ended June 30, 2003 assumes that the DIANON acquisition, which was closed by the Company on January 17, 2003, was acquired on January 1, 2003: Six Months Ended June 30, 2003 ---------------- Net sales $1,463.9 Net earnings 160.4 Diluted earnings per common share $ 1.10 8. GOODWILL AND INTANGIBLE ASSETS The changes in the carrying amount of goodwill (net of accumulated amortization) for the six-month period ended June 30, 2004 and for the year ended December 31, 2003 are as follows: June 30, 2004 December 31, 2003 ------------- ----------------- Balance as of January 1 $ 1,285.9 $ 910.1 Goodwill acquired during the period 18.8 388.7 Adjustments to goodwill 1.2 (12.9) -------- -------- Balance at end of period $ 1,305.9 $ 1,285.9 ======== ======== The components of identifiable intangible assets are as follows: June 30, 2004 December 31, 2003 ----------------------- ----------------------- Gross Gross Carrying Accumulated Carrying Accumulated Amount Amortization Amount Amortization ----------------------- ----------------------- Customer lists $ 596.1 $ 132.8 $ 582.5 $ 118.1 Patents, licenses and technology 67.7 14.5 67.2 11.1 Non-compete agreements 25.4 19.2 23.0 18.1 Trade name 49.5 5.2 49.6 3.6 ------- ------- ------- ------- $ 738.7 $ 171.7 $ 722.3 $ 150.9 ======= ======= ======= ======= Amortization of intangible assets for the six month and three month periods ended June 30, 2004 was $20.8 and $10.5, respectively, and $18.0 and $9.5 for the six month and three month periods ended June 30, 2003. Amortization expense for the net carrying amount of intangible assets is estimated to be $21.0 for the remainder of fiscal 2004, $42.3 in fiscal 2005, $40.9 in fiscal 2006, $39.4 in fiscal 2007, and $37.2 in fiscal 2008.

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 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. The plaintiffs have recently filed a consolidated amended complaint. On July 16, 2004, the defendants filed a motion to dismiss this complaint and continue 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.

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) 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, with total damages and attorneys fees payable by the Company of approximately $7.8 million. The Company appealed the case to the United States Court of Appeals for the Federal Circuit. On June 8, 2004, that Court affirmed the judgment against the Company. On June 22, 2004 the Company filed a request for rehearing of the decision. The Company plans to continue to vigorously contest the Judgment until it exhausts all reasonable appellate rights. The Company has recorded a reserve for this potential settlement. 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. 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

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) 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 June 30, 2004 and 2003, the Company had provided letters of credit aggregating approximately $52.9 and $46.1 respectively, primarily in connection with certain insurance programs. 11. PENSION AND POSTRETIREMENT PLANS Substantially all employees of the Company are covered by a defined benefit retirement plan (the "Company Plan"). The benefits to be paid under the Company Plan are based on years of credited service and average final compensation. The Company's policy is to fund the Company Plan with at least the minimum amount required by applicable regulations. The Company has a second defined benefit plan which covers its senior management group that provides for the payment of the difference, if any, between the amount of any maximum limitation on annual benefit payments under the Employee Retirement Income Security Act of 1974 and the annual benefit that would be payable under the Company Plan but for such limitation. This plan is an unfunded plan. The components of net periodic pension cost for both of the defined benefit plans are summarized as follows: Three Months Six Months Ended June 30, Ended June 30, ----------------- ----------------- 2004 2003 2004 2003 ----------------- ----------------- Components of net periodic benefit cost Service Cost $ 3.6 $ 3.1 $ 6.8 $ 6.2 Interest Cost 3.2 3.2 6.3 6.4 Expected return on plan assets (4.2) (3.2) (7.9) (6.4) Net amortization and deferral 0.4 0.9 0.8 1.8 ----- ----- ----- ----- Net periodic pension cost $ 3.0 $ 4.0 $ 6.0 $ 8.0 ===== ===== ===== =====

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) The Company assumed obligations under a subsidiary's postretirement medical plan.

The components of postretirement benefit expense are as follows: Three Months Six Months Ended June 30, Ended June 30, --------------- ---------------- 2004 2003 2004 2003 --------------- ---------------- Components of post retirement benefit expense Service Cost $ 0.3 $ 0.2 $ 0.5 $ 0.4 Interest Cost 0.8 0.8 1.8 1.6 Net amortization and deferral (0.5) (0.5) (1.0) (1.0) Amortization of actuarial loss 0.3 0.2 0.7 0.4 ----- ----- ----- ------ Postretirement benefit expense $ 0.9 $ 0.7 $ 2.0 $ 1.4 ===== ===== ===== ====== The Company previously disclosed in its financial statements for the year ended December 31, 2003, that it expected to contribute $34.6 to its defined pension plan in 2004. As of June 30, 2004, $20.6 of contributions have been made. The Company presently anticipates contributing an additional $14.0 to fund its pension plan in 2004 for a total of $34.6.

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 by 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. 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; 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 the 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 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, which could result in impairment in the value of certain capitalized licensing costs; 17.inability to obtain and maintain adequate patent and other proprietary rights protection of the Company's products and services and successfully enforce the Company's proprietary rights; 18.the scope, validity and enforceability of patents and other proprietary rights held by third parties which might have an impact on the Company's ability to develop, perform, or market the Company's tests or operate its business; 19.failure in the Company's information technology systems resulting in an increase in testing turnaround time or billing processes; 20.liabilities that result from the inability to comply with new Corporate governance requirements; and 21.compliance by the Company with the Sarbanes-Oxley Act of 2002, including Section 404 of that Act which requires management to report on, and our independent registered public accounting firm to attest to and report on, our internal controls, will require management to devote substantial time and attention, which could prove to be disruptive to product development and licensing, marketing and other business activities and will require additional legal, accounting and other expenses to implement the requirements of these new rules.

RESULTS OF OPERATIONS As discussed in the Company's Annual Report for the year ended December 31, 2003, the Company acquired DIANON Systems, Inc. on January 17, 2003. All dollar amounts are in millions. Three Months ended June 30, 2004 compared with Three Months ended June 30, 2003. Net sales for the three months ended June 30, 2004 were $784.3 an increase of $40.6, or approximately 5.5%, from $743.7 for the comparable 2003 period. The sales increase is a result of an increase of approximately 5.0% in volume (primarily volume growth in genomic and esoteric testing of approximately 10% as well as volume growth of approximately 4% in the base business). Price increased by approximately 0.5% for the quarter. Cost of sales, which includes primarily laboratory and distribution costs, was $444.6 for the three months ended June 30, 2004 compared to $427.2 in the corresponding 2003 period, an increase of $17.4, or 4.1%. The increase in cost of sales is primarily the result of increases in volume discussed above. Cost of sales as a percentage of net sales was 56.7% for the three months ended June 30, 2004 and 57.4% in the corresponding 2003 period. Cost of sales as a percentage of sales was impacted by the Company's ongoing cost reduction programs. Selling, general and administrative expenses increased to $165.0 for the three months ended June 30, 2004 from $164.1 in the same period in 2003. As a percentage of net sales, selling, general and administrative expenses were 21.0% and 22.1% for the three months ended June 30, 2004 and 2003, respectively. This decrease in selling, general and administrative expenses as a percentage of net sales is a result of realized synergies from the Dynacare and DIANON acquisitions, as well as a reduced effective bad debt expense rate, resulting from improved billing performance. The amortization of intangibles and other assets was $10.5 and $9.5 for the three months ended June 30, 2004 and 2003. The increase in the amortization expense for the three months ended June 30, 2004 is a result of small acquisitions. Interest expense was $9.3 for the three months ended June 30, 2004 compared with $10.0 for the same period in 2003. This decrease was a direct result of debt reductions following the Company's financing of the DIANON acquisition in 2003. Income from equity investments was $12.1 for the three months ended June 30, 2004 compared with $11.3 for the same period in 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 provision for income taxes as a percentage of earnings before taxes was 41.0% for the three month periods June 30, 2004 and 2003.

Six Months ended June 30, 2004 compared with Six Months ended June 30, 2003. Net sales for the six months ended June 30, 2004 were $1,536.8, an increase of $80.9, or 5.6%, from $1,455.9 for the same period in 2003. The sales increase is a result of an increase in volume (primarily volume growth in genomic and esoteric testing of approximately 10% as well as volume growth of approximately 5% in the base business). Price was essentially flat for the first six months. Cost of sales, which includes primarily laboratory and distribution costs, was $879.5 for the six months ended June 30, 2004 compared to $842.9 for the same period of 2003, an increase of $36.6, or 4.3%. The increase in cost of sales is primarily the result of increases in volume discussed above. Cost of sales as a percentage of net sales was 57.2% for the six months ended June 30, 2004 and 57.9% for the same period in 2003. Cost of sales as a percentage of sales was impacted by the Company's ongoing cost reduction programs. Selling, general and administrative expenses increased to $328.0 for the six months ended June 30, 2004 from $327.4 for the same period in 2003. As a percentage of net sales, selling, general and administrative expenses were 21.3% and 22.5% for the three months ended June 30, 2004 and 2003, respectively. This decrease in selling, general and administrative expenses as a percentage of net sales is a result of realized synergies from the Dynacare and DIANON acquisitions, as well as a reduced effective bad debt expense rate, resulting from improved billing performance. The amortization of intangibles and other assets was $20.8 and $18.0 for the six months ended June 30, 2004 and 2003. The increase in the amortization expense for the six months ended June 30, 2004 is a result of small acquisitions. Interest expense was $18.6 for the six months ended June 30, 2004 compared with $21.4 for the same period in 2003. This decrease was a direct result of debt reductions following the Company's financing of the DIANON acquisition in 2003. The provision for income taxes as a percentage of earnings before taxes was 41.0% for the six months ended June 30, 2004 compared to 40.8% for the six months ended June 30, 2003. LIQUIDITY AND CAPITAL RESOURCES Net cash provided by operating activities was $294.3 and $258.2 for the six months ended June 30, 2004 and June 30, 2003, respectively. The increase in cash flows from operations primarily resulted from improved earnings, the expansion of the business through acquisitions, and the improvement of the Company's accounts receivable days' sales oustanding ("DSO") to 52 days at June 30, 2004 from 54 days at June 30, 2003. Capital expenditures were $42.6 and $37.4 at June 30, 2004 and 2003, respectively. The Company expects total capital expenditures of approximately $90.0 to $100.0 in 2004. These expenditures are intended to continue to improve information systems and further

automate laboratory processes. Such expenditures are expected to be funded by cash flow from operations. On December 17, 2003, the Company's Board of Directors authorized a stock repurchase program under which the Company may purchase up to an aggregate of $250.0 of its common stock from time- to-time, beginning in the first quarter of 2004. During the first six months of 2004, the Company purchased approximately 4.6 million shares of its common stock totaling $182.1 with cash flow from operations. It is the Company's intention to fund future purchases of its common stock with cash flow from operations. 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. CONTRACTUAL CASH OBLIGATIONS Payments Due by Period at June 30, 2004 --------------------------------------- < 1 Yr 1-3 Yrs 3-5 Yrs > 5 Yrs --------------------------------------- Capital lease obligations $ 1.4 $ 2.5 $ 1.2 $ -- Operating leases 57.5 75.3 34.1 25.3 Restructuring obligations 2.3 6.4 5.9 6.4 Contingent future licensing payments(a) 9.7 31.1 19.0 0.4 Royalty payments 0.3 1.8 2.0 -- 5 1/2% Senior Notes -- -- -- 350.0 Zero Coupon- Subordinated Notes 530.5(b) -- -- -- ----- ----- ----- ----- Total contractual Cash obligations $601.7 $117.1 $ 62.2 $382.1 ===== ===== ===== ===== (a) Contingent future licensing payments will be made in the event that certain events take place, such as the launch of a specific test, the transfer of certain technology, and when specified revenue milestones are met. (b) Holders of the zero coupon-subordinated notes may require the Company to purchase all or a portion of their notes on September 11, 2004, 2006 and 2011 at prices ranging from $712.97 to $819.54 per note. 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. However, future market conditions are subject to change. Should the holders put the notes to the Company on any of the dates above, the Company believes that it will be able to satisfy this contingent obligation with cash on hand, borrowings on the revolving credit facility, and additional financing if necessary.

EITF NO 04-8 "THE EFFECT OF CONTINGENTLY CONVERTIBLE DEBT ON DILUTED EARNINGS PER SHARE" In July 2004, the Emerging Issues Task Force ("EITF") of the Financial Accounting Standards Board provided a tentative conclusion on EITF Issue No. 04-8, "The Effect of Contingently Convertible Debt on Diluted Earnings per Share." Under the EITF's tentative conclusion, contingently convertible shares attached to a debt instrument are to be included in the calculation of diluted earnings per share regardless of whether the contingency has been met. Historically the Company has followed the guidance of paragraph 30 of SFAS No. 128, "Earnings Per Share", and excluded these contingently convertible shares from its calculations of diluted earnings per share. If a final consensus is reached in support of the tentative EITF conclusion, the Company would be required to adopt the provisions of EITF No 04-8 for its zero coupon-subordinated notes for periods ending after December 15, 2004, including the retroactive restatement of all diluted earnings per share calculations for all periods presented. The EITF Issue No 04-8 is currently subject to a comment period and the EITF will review the comments at its September 2004 meeting. Based on a review of the provisions of the Issue No 04-8, the Company has determined that the adoption would result in the reduction of its diluted earnings per share. Using the "if converted" method as if the zero coupon-subordinated notes had been converted as of January 1, 2004, diluted income per share of common stock from continuing operations would have been reduced by approximately $0.03, to $0.67; and by $0.06, to $1.24; for the three and six months ended June 30, 2004, respectively. However, the exact amount of dilution cannot be determined until final guidance is provided by the EITF. 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. The Company had an interest rate swap agreement with a major financial institution, solely to manage its interest rate exposure on $175.0 million of its 5 1/2% senior notes. This swap agreement was terminated during June 2003 and the Company received net proceeds of $5.3 million. 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 SFAS 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 June 30, 2004. 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 as of the end of the second fiscal quarter.

Item 5. Other Information Senior Executive Transition Policy In April 2004, the Compensation Committee recommended to the Board of Directors, and the Board adopted, a Senior Executive Transition Policy (the "Policy"). An Executive Officer is eligible for benefits under this Policy if: (1) he or she held office as the President/CEO or an Executive Vice President on or after April 1, 2004; (2) at the time of his or her voluntary termination, has been an Executive Vice President or President/CEO of LabCorp for at least five years; (3) has been credited with at least 10 years of service under the LabCorp Employees' Retirement Savings Plan at their termination date; and (4) has entered into a non-competition agreement with the Company within 30 days of the adoption of the Policy or his or her appointment as an Executive Vice President or President/CEO. If a qualifying executive resigns before attaining age 65, the departed executive's restricted stock and stock option awards will continue to vest and be exercisable on the same terms as if the executive had continued his or her employment with LabCorp. The benefits of the Policy will be available only if the executive officer complies with the terms of the Policy regarding (a) minimizing any possible adverse effect on shareholders of his or her announcement of and statements regarding, a decision or intention to terminate employment before age 65; (b) the reasonableness of the period between his or her announcement of a decision or intention to retire and the announced and/or actual termination date; and (c) compliance with an individualized plan to be developed by the Board of Directors for the transition of his or her duties to others, including a successor.

EXHIBIT 10.1

Laboratory Corporation of America Holdings
Senior Executive Transition Policy


     This Senior Executive Transition Policy ("the Policy") is
adopted to state in a single document the policy of Laboratory
Corporation of America Holdings ("LabCorp") regarding Awards made
under Stock Incentive Plans to a Senior Executive if the Senior
Executive thereafter voluntarily terminates employment with LabCorp
before reaching age 65.  For purposes of this Policy, the term
"Senior Executive" means a duly appointed President/CEO or Executive
Vice President of LabCorp.  The term "Stock Incentive Plan" means the
Laboratory Corporation of America Holdings 1994 Stock Option Plan,
the Laboratory Corporation of America Holdings 2000 Stock Option
Plan, and any plan of a like kind that may be adopted hereafter.  The
term "Award" means an Award as defined in a Stock Incentive Plan.

1.  This Policy applies only to Eligible Senior Executives.  An
"Eligible Senior Executive" is a Senior Executive who has
satisfied the requirements of Paragraph 2 of this Policy
(relating to a Confidentiality/Non-Compete Letter), who held
office as the President/CEO or an Executive Vice President of
LabCorp on or after April 1, 2004, and who at the time of his or
her voluntary termination has served as a Senior Executive of
LabCorp for at least five years and has been credited with at
least ten "Years of Service" as defined in the Laboratory
Corporation of America Employees' Retirement Savings Plan.

2.   A Senior Executive satisfies the requirement of this Paragraph 2
of the Policy if he or she executes a Confidentiality/Non-
Compete Letter substantially in the form attached as Exhibit A
within 30 days of the later of the adoption of this Policy or
his or her appointment as a Senior Executive, and if he or she
executes such amended forms of such a letter as may reasonably
be required by the Board of Directors from time to time.

3.  If an Eligible Senior Executive resigns from office and
terminates employment with LabCorp and its affiliates before
reaching age 65, and the Compensation Committee finds that the
Eligible Senior Executive's transition satisfies the transition
requirements described in Paragraph 4 of this Policy, then
LabCorp, acting through the Compensation Committee of the Board
of Directors, will take all steps necessary and proper to cause
all Unexpired Awards to continue to be eligible for vesting and
to continue to be or become exercisable, payable, or eligible
for the termination of restrictions (as the case may be)
following termination of employment on the same terms and
conditions as if the Eligible Senior Executive had remained
employed by LabCorp during the original exercise period (or, in
the case of an Eligible Senior Executive who dies following
resignation from office and termination of employment, as if the
Eligible Senior Executive had remained so employed through the
date of death).  An "Unexpired Award" means an Award granted to
the Eligible Senior Executive that had not expired and, in the
case of an Award that is an option, had not been exercised; in
the case of an Award that consists of restricted stock, had not
yet become free of restrictions; or, in the case of any other
Award, had not become payable as of the date of his or her
termination of employment with LabCorp.

4.   The transition requirements referred to in Paragraph 3 of this
Plan are as follows:

(a) the Eligible Senior Executive's announcement of a decision
or intention to terminate before age 65 ("Announcement"), and
his or her subsequent public statements regarding his or her
decision or intention to terminate employment, are each made at
a time and in a manner reasonably calculated to minimize any
adverse effect the Announcement and/or any such statement might
have on the shareholders of LabCorp;

(b) the Eligible Senior Executive's Announcement, his or her
announced termination date, and (if different) his or her actual
termination date, whether considered individually or in
conjunction with the dates of the Announcement, the scheduled
termination dates, and/or the actual termination dates of any
other Senior Executives, do not occur within a period of time
that the Compensation Committee finds unreasonably short;

(c) following his or her Announcement, the Eligible Senior
Executive cooperates to the full satisfaction of the
Compensation Committee in the Board of Directors' development of
a plan (the "Transition Plan") for the transition of his or her
duties to others, including his or her successor; and the
Eligible Senior Executive executes his or her duties under the
Transition Plan to the full satisfaction of the Compensation
Committee.  A Senior Executive's duties under a Transition Plan
may include (without limitation) taking all steps assigned to
him or her by the Board in connection with the search for and/or
selection of a successor, and active cooperation in training a
successor and fully familiarizing the successor with sources of
relevant information necessary to carrying out the successor's
duties.

5.   This Policy may be modified, terminated, or amended at any time
by the Compensation Committee, provided, however, that no
modification, termination, or amendment of the Policy adopted
after a Senior Executive has made an Announcement will apply to
such Senior Executive without his or her written consent.

 [NAME]
President OR Executive Vice President
Laboratory Corporation of America Holdings
430 S. Spring Street, First Floor
Burlington, NC 27215

Dear ________________:

This letter is intended to memorialize your agreement, as the
_________________________ of Laboratory Corporation of America
Holdings ("the Company"), to certain duties of confidentiality, non-
competition, and similar matters during your employment, and
following your termination of employment, with the Company and any of
its affiliates (collectively, "LabCorp").  If you sign and return
this letter on or before _________ __, 2004, you will satisfy the
requirement of Section 2 of the Senior Executive Transition Policy
for being an "Eligible Senior Executive" as defined in that Policy.

Defined Terms.  For purposes of this letter, "Laboratory Testing"
refers to the collection for testing and/or testing of specimens from
human beings for the purposes of diagnosis, treatment, or care of
disease or illness; monitoring or providing data for the analysis of
a regimen of treatment, a therapy, or a diagnostic or therapeutic
procedure; and/or detection or analysis of the presence or absence of
factors, chemicals or compounds.  "Clinical Trial" refers to
assembling, validating, or analyzing data relating to the safety or
effectiveness of a drug or medical device.

Receipt of Confidential Information.  You acknowledge that in the
course of your employment with LabCorp, you have developed and will
develop an extensive knowledge of LabCorp's business, including but
not limited to business strategies, cost information, marketing
information, product and service information, new products and
services under development, and plans for the expansion of product
and service lines (including, without limitation, plans for the
acquisition or licensing of intellectual property relating to
Laboratory Testing).  In addition, you acknowledge that in your
employment you have access to information regarding LabCorp's
business plans, sales methods, and customers on a corporate-wide
basis in every market in which LabCorp conducts business.  The
knowledge and information referred to above will be referred to as
"Confidential Information."

Competition.  You and the Company agree that LabCorp will suffer
significant and irreparable injury, for which damages at law would
not be a measurable or adequate remedy, if you become employed by any
corporation or entity that competes with LabCorp or if you provide
services to any such corporation or entity in any other capacity that
would permit you to take advantage of the Confidential Information
acquired by you during the course of your employment with LabCorp
(including by breaching any of the numbered covenants contained in
this paragraph).  Accordingly, you agree that during your employment
by LabCorp and for a period of two (2) years following your
termination of employment, you will not, directly or indirectly:

1. Become employed by or otherwise become interested in (as
owner, stockholder, partner, co-venturer, director, officer,
employee, agent, consultant, or otherwise) any corporation or
entity that is engaged (a) in the business of Laboratory Testing
in the United States and/or Canada at a location that is within
five (5) miles of any location at which one or more employees of
LabCorp is regularly engaged in any aspect of the business of
Laboratory Testing (including, without limitation, any regular
collection site served by LabCorp); or (b) that is engaged in
the business of Clinical Trials in a country in which LabCorp is
engaged in the business of Clinical Trials.  This paragraph
shall not prevent you from holding not more than five (5)
percent of the outstanding securities of any class of any
publicly traded company, other than a company primarily engaged
in Laboratory Testing.

2. Solicit sales or business from any corporation or entity that
was a customer of LabCorp within the one-year time period
preceding your termination of employment provided, however, that
the solicitation of sales of products or services not offered by
LabCorp at the time of such solicitation shall not be deemed a
violation of this provision.

3. Employ or retain, or arrange to have any other person or
entity employ or retain, any person who shall have been employed
or retained by LabCorp as a director or officer at any time
during the one-year time period preceding the termination of
your employment.

4. Attempt to influence any director or officer of LabCorp to
terminate or modify his or her employment arrangement with
LabCorp.

You agree that the foregoing restrictions are necessary for the
reasonable and proper protection of the Company; are reasonable in
respect to subject matter, length of time, geographic scope, customer
scope, and scope of activity to be restrained; and are not unduly
harsh and oppressive so as to deprive you of a livelihood or to
unduly restrict your opportunity to earn a living after termination
of your employment with the Company.

Confidentiality.  During the term of your employment with LabCorp and
thereafter, except as required by or pursuant to law, you shall not,
without the written consent of the Board or a person authorized
thereby, disclose to any person, other than an employee of LabCorp or
a person to whom disclosure is reasonably necessary or appropriate in
connection with the performance by you of your duties as a Senior
Executive of LabCorp, any Confidential Information or Business
Information obtained by you while in the employ of LabCorp.  The term
"Business Information" means any information pertaining to LabCorp's
conduct of its Laboratory Testing and/or Clinical Trial business that
is not readily and easily available to the public or to those in
LabCorp's industry, including, without limitation, LabCorp's prices,
pricing methods, costs, profits, profit margins, suppliers,
procedures, processes, research and development projects, data,
goals, activities, business strategies, marketing techniques, the
identities or addresses of LabCorp's employees, the functions of
LabCorp's employees, and any customer-related information.

Property.  During the term of this Agreement, you shall not make,
copy, maintain, distribute, divulge the contents of, or remove from
LabCorp's offices or premises any documents, records, or similar
materials containing Confidential Information or Business Information
unless necessary or appropriate in accordance with your duties and
responsibilities as [President OR Executive Vice President].  Upon
termination of your employment with LabCorp, you shall leave with or
immediately return to LabCorp all originals and copies of the
foregoing LabCorp property then in your possession, whether prepared
by you or by others.

Duty of Loyalty/Nondisparagement.  During the term of your employment
and for a period of five years following your termination of
employment, you will not (except as required by or pursuant to law)
communicate to anyone, whether by word or deed, whether directly or
through any intermediary, and whether expressly or by suggestion or
innuendo, any statement, whether characterized as one of fact or of
opinion, that is intended to cause or that reasonably would be
expected to cause any person to whom it is communicated to have (1) a
lowered opinion of the Company or any affiliate, including a lowered
opinion of any products manufactured, sold, or used by, or any
services offered or rendered by the Company or any affiliate; and/or
(2) a lowered opinion of the creditworthiness or business prospects
of the Company or any affiliate.

Interpretation and Enforcement.  You and the Company agree that this
letter will be interpreted and construed under the laws of North
Carolina (exclusive of any laws relating to choice of law in the
event of conflicts of law and of any principle causing ambiguities to
be construed against the drafter), and that the covenants contained
in the Competition portion of this letter will be construed and
interpreted so as to permit their enforcement to the maximum extent
permitted thereunder (including, to the extent necessary, by treating
each provision of this letter as severable and separately
enforceable, and/or by reforming any such separate provisions to the
minimum extent necessary to permit enforcement of such covenants to
the fullest extent permitted).  You consent to the exclusive
jurisdiction of the courts of North Carolina over any action or
proceeding relating to the validity and/or construction of this
letter, and agree that you will not bring or remove any such action
or proceeding other than in or to a court established by the State of
North Carolina.

If this Agreement is acceptable to you, please sign and date this
letter where indicated below.
