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. 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 annual report. 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. RECLASSIFICATIONS In 1999, the Company reclassified $31.0 for the six-months ended June 30, 1998 and $16.3 for the three-months ended June 30, 1998 to selling, general and administrative expenses from net sales adjustments to be consistent with the 1999 classification. The reclassification had no effect on operating income. 3. EARNINGS PER SHARE Basic and diluted earnings (loss) per share are based upon the weighted- average number of shares outstanding during the three- and six-months ended June 30, 1999 of 126,258,380 shares and 126,199,250 shares, respectively, and the weighted-average number of shares outstanding during the three- and six- months ended June 30, 1998 of 124,506,673 shares and 124,452,465 shares, respectively. The effect of conversion of the Company's redeemable preferred stock, or exercise of the Company's stock options or warrants was not included in the computation of diluted earnings per common share as it would have been antidilutive for all applicable periods presented.

ACCUMULATED OTHER COMPREHENSIVE INCOME At June 30, 1999, the Company recorded an unrealized loss on its shares of Universal Standard Healthcare, Inc. of $0.4, net of related deferred tax benefit of $0.3.

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) 6. INTEREST RATE SWAP The existing rate collar transaction and swap have effectively changed the interest exposure on $500.0 of floating rate debt to a weighted-average fixed interest rate of 6.04%. The notional amounts of the agreements are used to measure interest to be paid or received and do not represent the amount of exposure to credit loss. 7. LONG-TERM DEBT The Third Amendment to the Amended and Restated Credit Agreement became effective on May 7, 1999. This amendment primarily addresses leverage ratio requirements, Year 2000 issues, increases the amount of the acquisition covenant, and provides the Company with the ability to purchase a limited amount of Preferred Stock. The Company made scheduled loan payments of $11.6 on March 31, 1999 and $11.1 on June 30, 1999 on its Amended Term Loan Facility. In addition, the Company made a special payment on its Amended Term Loan Facility on April 15, 1999 of $25.3, based on a contractual formula contained in the Amended Credit Agreement. During the second quarter of 1999, the Company borrowed $30.0 on its revolving credit facility and repaid $10.0 of that outstanding balance. 8. COMMITMENTS AND CONTINGENCIES The Company is involved in litigation which purports to be a class action brought on behalf of certain patients, private insurers and benefit plans that paid for laboratory testing services during the time frame covered by the 1996 Government Settlement. The Company has also received certain similar claims brought on behalf of certain other insurance companies, some of which have been resolved for immaterial amounts. These claims for private reimbursement are similar to the government claims settled in 1996. However, no amount of damages has been specified at this time and, with the exception of the above, no settlement discussions have taken place. The Company is carefully evaluating these claims, however, due to the early stage of the claims, the ultimate outcome of these claims cannot presently be predicted. The Company is also involved in certain claims and legal actions arising in the ordinary course of business. These matters include, but are not limited to, inquiries from governmental agencies and Medicare or Medicaid carriers 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 will not 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) 9. NEW ACCOUNTING PRONOUNCEMENTS In June 1998, Statement of Financial Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging Activities," was issued. This Statement standardizes the accounting for derivative instruments by requiring that an entity recognize those items as assets or liabilities and measure them at fair value. In June 1999, Statement of Financial Accounting Standards No. 137 "Accounting for Derivative Instruments and Hedging Activities - Deferral of the Effective Date of FASB No. 133" was issued. This Statement delayed the effective date of Statement No. 133 for one year, to fiscal years beginning after June 15, 2000. Adoption is not expected to have a material impact on the Company's financial position or results of operations. OVERVIEW - -------- This quarterly report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. In addition, from time to time, the Company or its representatives have made or may make forward-looking statements, orally or in writing. Such forward- looking statements may be included in, but are not limited to, various filings made by the Company with the Securities and Exchange Commission, press releases or oral statements made by or with the approval of an authorized executive officer of the Company. Actual results could differ materially from those projected or suggested in any forward-looking statements as a result of a wide variety of factors and conditions, which have been described in the section of the Company's Annual Report on Form 10-K for the year ended December 31, 1998, entitled, "Cautionary Statement for Purposes of the `Safe Harbor' Provisions of the Private Securities Litigation Reform Act of 1995" and other documents the Company files from time to time with the Securities and Exchange Commission including the Company's quarterly reports on Form 10-Q and current reports on Form 8-K, and shareholders are specifically referred to these documents with regard to factors and conditions that may affect future results. RESULTS OF OPERATIONS - --------------------- Three Months ended June 30, 1999 compared with Three Months ended June 30, 1998. Net sales for the three months ended June 30, 1999 were $429.5, an increase of approximately 6.7% from $402.4 for the comparable 1998 period. The sales increase is a result of a 2.3% increase in price and a 4.4% increase in testing volume. The increase in sales for the second quarter of 1999 would have been approximately 5.0% after excluding the effect of the three acquisitions made in 1998 (Universal Standard Healthcare, Inc., Medlab and Coastal Medical).

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) Cost of sales, which includes primarily laboratory and distribution costs, was $265.2 for the three months ended June 30, 1999 compared to $257.8 in the corresponding 1998 period, an increase of $7.4. Cost of sales increased $11.1 due to the increase in volume and $5.3 primarily due to testing supplies and consulting fees. These increases were partially offset by decreases totaling $7.0 in salaries and benefits, telephone, report and request forms and depreciation expenses. Cost of sales as a percentage of net sales was 61.7% for the three months ended June 30, 1999 and 64.1% in the corresponding 1998 period. The decrease in the cost of sales percentage of net sales primarily resulted from the Company's continued cost reduction efforts. Selling, general and administrative expenses increased to $114.4 for the three months ended June 30, 1999 from $99.7 in the same period in 1998. The primary reason for the increase is due to an increase to bad debt expense. Bad debt expense increased $10.9 as a result of increased sales and delays in payments from several large managed care and hospital payors in specific regions of the country. See "Liquidity and Capital Resources." In addition, Year 2000 project expenses recorded during the three months ended June 30, 1999, totaled approximately $1.2. As a percentage of net sales, selling, general and administrative expenses were 26.6% and 24.8% for the three months ended June 30, 1999 and 1998, respectively. The increase in the selling, general and administrative percentage primarily resulted from the bad debt increase as noted above. The amortization of intangibles and other assets was $7.8 and $7.5 for the three months ended June 30, 1999 and 1998, respectively. Net interest expense was $10.1 for the three months ended June 30, 1999 compared with $11.9 for the same period in 1998. As previously discussed, the interest rate that the Company pays on its debt is linked to the Company's financial performance. As of September 30, 1998, the interest rate that the Company pays on its long term debt was reduced from LIBOR plus 1.0% to LIBOR plus 0.5% and from 0.75% to 0.3125% on its revolving debt. This decrease, along with the reduction of outstanding indebtedness and the general decline in interest rates over the past year, has reduced the Company's interest by $1.7. The provision for income taxes as a percentage of earnings before taxes was 38.0% for the three months ended June 30, 1999 compared to 49.6% for the three months ended June 30, 1998. During the three months ended June 30, 1999, the Company reduced its valuation allowance applied against its deferred tax assets by $2.5, thereby reducing its provision for income taxes as a percentage of earnings before taxes.

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) SIX MONTHS ENDED JUNE 30, 1999 COMPARED WITH SIX MONTHS ENDED JUNE 30, 1998. Net sales for the six months ended June 30, 1999 were $847.4, an increase of approximately 7.2% from $790.0 reported in the comparable 1998 period. The sales increase is a result of a 3.9% increase in volume and a 3.3% increase in price. Cost of sales, which includes primarily laboratory and distribution costs, was $531.7 for the six months ended June 30, 1999 compared to $513.5 in the corresponding 1998 period, an increase of $18.2. Cost of sales increased approximately $19.6 due to the increase in volume and approximately $10.1 due to increases in personnel expense, testing supplies and consulting fees. These increases were partially offset by decreases totaling $9.0 in telephone, depreciation, report and request forms and insurance expenses. Cost of sales as a percentage of net sales was 62.7% for the six months ended June 30, 1999 and 65.0% in the corresponding 1998 period. The decrease in the cost of sales percentage of net sales primarily resulted from the Company's continued cost reduction efforts. Selling, general and administrative expenses increased to $223.5 for the six months ended June 30, 1999 from $194.7 in the same period in 1998. The primary reason for the increase is due to an increase to bad debt expense. Bad debt expense increased $23.0 as a result of increased sales and delays in payments from several large managed care and hospital payors in specific regions of the country. See "Liquidity and Capital Resources." In addition, Year 2000 project expenses recorded during the six months ended June 30, 1999, totaled approximately $2.7. As a percentage of net sales, selling, general and administrative expenses were 26.4% and 24.6% for the six months ended June 30, 1999 and 1998, respectively. The increase in the selling, general and administrative percentage primarily resulted from the bad debt increase as noted above. The amortization of intangibles and other assets was $15.7 and $15.2 for the six months ended June 30, 1999 and 1998, respectively. Net interest expense was $20.5 for the six months ended June 30, 1999 compared with $24.4 for the same period in 1998. As of September 30, 1998, the interest rate that the Company pays on its long term debt was reduced from LIBOR plus 1.0% to LIBOR plus 0.5% and from 0.75% to 0.3125% on its revolving debt. This decrease, along with the reduction of outstanding indebtedness and the general decline in interest rates over the past year, has reduced the Company's interest by $3.9.

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) The provision for income taxes as a percentage of earnings before taxes was 38.0% for the six months ended June 30, 1999 compared to 50.0% for the six months ended June 30, 1998. During the six months ended June 30, 1999, the Company reduced its valuation allowance applied against its deferred tax assets by $5.0, thereby reducing its provision for income taxes as a percentage of earnings before taxes. LIQUIDITY AND CAPITAL RESOURCES - ------------------------------- Net cash provided by operating activities was $75.9 and $65.4 for the six months ended June 30, 1999 and June 30, 1998, respectively. The increase in cash flow from operations primarily resulted from improved earnings. Capital expenditures were $36.9 and $28.7 for the first six months of 1999 and 1998, respectively. The Company's days sales outstanding (DSO) at June 30, 1999 was 79 days, compared to 83 days at the end of the first quarter. The Company is focusing on reducing its DSO through the conversion of the entire Company to a single, centralized billing system. The Company expects to be substantially converted to the new billing system by the end of the year 2000. For a discussion of legal proceedings which may impact the Company's liquidity and capital resources see "Note 8 to the Company's Unaudited Condensed Consolidated Financial Statements". Cash and cash equivalents on hand, cash flows from operations and additional borrowing capabilities under the Amended Revolving Credit Facility are expected to be sufficient to meet anticipated operating requirements and provide funds for capital expenditures, potential acquisitions and working capital for the foreseeable future. YEAR 2000 UPDATE - ---------------- The Company has an ongoing effort to identify and remediate data recognition problems that will be caused in computer systems, software, and lab equipment by the change in date from the year 1999 to the year 2000. The Company is also working to address potential problems in systems and equipment that contain imbedded hardware or software that may have a time element (referred to as "non-IT" systems). The Company's Year 2000 project has five phases: i) inventory of the business critical functional equipment and systems affected by the Year 2000 issue; ii) assessment of the key elements identified by the inventory including development of strategies to address affected critical equipment and systems; iii) contingency planning; iv) remediation of affected equipment and systems; and v) testing and validation of its systems for Year 2000 date recognition. Inventories of business critical functional equipment and systems have been completed. Follow-up assessments of the key elements identified by the inventories and the development of strategies to

LABORATORY CORPORATION OF AMERICA HOLDINGS AND SUBSIDIARIES NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) address key equipment and systems have also been completed. Contingency planning is scheduled to be completed by the end of the third quarter of 1999. Completion of all material phases of remediation for business critical equipment and systems is scheduled for September 30, 1999. All material phases of testing and validation for business critical equipment and systems is scheduled to be completed by mid-October. The Company is also working to assess Year 2000 readiness on the part of its significant service providers, vendors, suppliers, customers and governmental entities. There can be no guarantee that the failure by these other companies to successfully and timely achieve Year 2000 compliance would not have an adverse effect on the Company's operations. The total cost associated with required Year 2000 modifications and related activities is not expected to be material to the Company's financial position and is expected to be funded through capital and operating cash flows. The Company estimates total Year 2000 expenditures to be $20.0 - $25.0 with approximately $3.0 charged to earnings during the year ended 1998 and $2.7 charged to earnings and an additional $3.2 in related purchases capitalized during the six-months ended June 30, 1999. The amounts required to address Year 2000 readiness do not include significant investments in new systems which have been and are being incurred in the normal course of business and are Year 2000 compliant. The estimates and conclusions herein contain forward-looking statements and are based on management's best estimates of future events. The failure to correct a material Year 2000 problem could result in an interruption in, or a failure of, certain normal business activities or operations. Such failures could materially and adversely affect the Company's results of operation, liquidity and financial condition. Due to the general uncertainty inherent in the Year 2000 problem, resulting in part from uncertainty of the Year 2000 readiness of third-party suppliers and customers, the Company is unable to determine at this time whether consequences of Year 2000 failures will have a material impact on the Company's results of operations, liquidity or financial condition.

       THIRD AMENDMENT TO AMENDED AND RESTATED CREDIT AGREEMENT

      THIRD  AMENDMENT TO AMENDED AND RESTATED CREDIT  AGREEMENT,
dated  as  of  May  7, 1999 (this "Amendment")  among  LABORATORY
CORPORATION  OF  AMERICA HOLDINGS,  a Delaware  corporation  (the
"Borrower"),   the  banks,  financial  institutions   and   other
institutional   lenders   (the   "Banks") listed on the signature
pages thereof, and CREDIT SUISSE FIRST BOSTON,  as administrative
agent (the "Administrative Agent") for the Lenders hereunder.

                      PRELIMINARY STATEMENTS

      The  parties  hereto (i) have entered into an  Amended  and
Restated Credit Agreement dated as of March 31, 1997, as  amended
as  of  September  30, 1997 and February 25,  1998  (the  "Credit
Agreement")  providing for, among other things,  the  Lenders  to
lend  to  the  Borrower up to $1,143,750,000  on  the  terms  and
subject  to the conditions set forth therein and (ii)  desire  to
amend the Credit Agreement in the manner set forth herein.   Each
capitalized  term  used  but not defined herein  shall  have  the
meaning ascribed thereto in the Credit Agreement.

     NOW, THEREFORE,in consideration of the premises and the mutual
covenants  and  agreements contained herein, the  parties  hereto
hereby agree as follows:

                             ARTICLE I

                      AMENDMENTS; AMENDMENT FEE

      SECTION 1.01.  Amendment to Representations and Warranties.
Section 4.01 of the Credit Agreement if hereby amended by  adding
the following new Section 4.01 (r):

      (r)  The Borrower has (i) initiated a review and assessment
of  all  areas within its and each of its Subsidiaries'  business
and  operations that could reasonably by expected to be adversely
affected  by  the  "Year  2000 Problem" (that  is, the  risk that
computer  applications  used  by  the  Borrower  or  any  of  its
Subsidiaries may be unable to recognize and perform properly date-
sensitive functions involving certain dates prior to and any date
after December 31, 1999), (ii) developed a plan and timeline  for
addressing  the Year 2000 Problem on a timely basis  (which  plan
includes    contingencies   and   testing   of   such    computer
applications),  and  (iii)  to date,  implemented  that  plan  in
accordance  with  that timetable.  Based on  the  foregoing,  the
Borrower believes that all computer applications within  its  and
its Subsidiaries' control that are material to  its or any of its
Subsidiaries'  business and  operations are  expected  to be able
to  perform  date-sensitive functions for all  dates  before  and
after January 1, 2000, except to the extent that a failure to  do
so  could  not reasonably be expected to have a Material  Adverse
Effect.   The  total cost associated with implementation  of  the
Borrower's  plan  for  addressing the Year 2000  Problem  is  not
expected to be material to the Borrower's financial position.

      SECTION  1.02.  Amendment to Leverage Ratio.  Section  5.01
(i)  of  the  Credit Agreement is hereby amended by deleting  the
figures shown with strike-over lines and replacing  such  figures
with  the figures indicated in boldface type and  underscored, to
read in its entirety as follows:

      (i)   Leverage  Ratio.  Maintain at the end  of  each  four
fiscal  quarter period specified below a Leverage  Ratio  of  not
more than the ratio set forth below:

           Section 1.03.  Amendment to Covenant Prohibiting Stock
Repurchases.  Section 5.02 (e) of the Credit Agreement is  hereby
