1. BASIS OF PRESENTATION

Background

Quest Diagnostics Incorporated and its subsidiaries ("Quest
Diagnostics" or the "Company") is the largest clinical laboratory testing
business in the United States. As the nation's leading provider of diagnostic
testing and related services for the healthcare industry, Quest Diagnostics
offers a broad range of clinical laboratory testing services to physicians,
hospitals, managed care organizations, employers, governmental institutions and
other independent clinical laboratories. Quest Diagnostics has the leading
market share in clinical laboratory testing and esoteric testing, including
molecular diagnostics, as well as non-hospital based anatomic pathology services
and testing for drugs of abuse. Through the Company's national network of
laboratories and patient service centers, and its esoteric testing laboratory
and development facilities, Quest Diagnostics offers comprehensive and
innovative diagnostic testing, information and related services used by
physicians and other healthcare customers to diagnose, treat and monitor
diseases and other medical conditions. Quest Diagnostics also offers clinical
testing and services to support clinical trials of new pharmaceuticals
worldwide.

On an annualized basis, Quest Diagnostics processes over 115 million
requisitions through its extensive network of laboratories and patient service
centers in virtually every major metropolitan area throughout the United States.

Basis of Presentation

The interim consolidated financial statements reflect all adjustments
which, in the opinion of management, are necessary for a fair statement of
financial condition and results of operations for the periods presented. Except
as otherwise disclosed, all such adjustments are of a normal recurring nature.
The interim consolidated financial statements have been compiled without audit.
Operating results for the interim periods are not necessarily indicative of the
results that may be expected for the full year. These interim consolidated
financial statements should be read in conjunction with the audited consolidated
financial statements included in the Company's 2001 Annual Report on Form 10-K.

Earnings Per Share

Basic earnings per common share is calculated by dividing net income,
less preferred stock dividends (approximately $30 thousand per quarter in 2001),
by the weighted average number of common shares outstanding. Diluted earnings
per common share is calculated by dividing net income, less preferred stock
dividends, by the weighted average number of common shares outstanding after
giving effect to all potentially dilutive common shares outstanding during the
period. The if-converted method is used in determining the dilutive effect of
the Company's 1 3/4% contingent convertible debentures in periods when the
holders of such securities are permitted to exercise their conversion rights.
Potentially dilutive common shares include outstanding stock options and
restricted common shares granted under the Company's Employees Equity
Participation Program. These dilutive securities increased the weighted average
number of common shares outstanding by 2.8 and 3.5 million shares for the three
and nine months ended September 30, 2002, respectively. For both the three and
nine months ended September 30, 2001, these dilutive securities increased the
weighted average number of common shares outstanding by 4.7 million shares.
During the fourth quarter of 2001, the Company redeemed all of its then issued
and outstanding shares of preferred stock.

Stock-Based Compensation

Quest Diagnostics has adopted the disclosure-only provisions of
Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for
Stock-Based Compensation" ("SFAS 123"), and follows Accounting Principles Board
Opinion ("APB") No. 25, "Accounting for Stock Issued to Employees" ("APB 25"),
and related interpretations to account for its stock-based compensation plans.
Under this approach, the cost of restricted stock awards is expensed over their
vesting period, while the imputed cost of stock option grants and discounts
offered under the Company's Employee Stock Purchase Plan ("ESPP") is disclosed,
based on the vesting provisions of the individual grants, but not charged to
expense. Stock-based compensation expense recorded in accordance with APB 25,
related to restricted stock awards, was $1.9 million and $4.6 million for the
three months ended September 30, 2002 and 2001, respectively, and $6.8 million
and $16.5 million for the nine months ended September 30, 2002 and 2001,
respectively.

New Accounting Standards

In August 2001, the Financial Accounting Standards Board ("FASB")
issued SFAS No. 144, "Accounting for Impairment or Disposal of Long-Lived
Assets" ("SFAS 144"), which supercedes SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets to be Disposed Of" ("SFAS 121"). SFAS 144
further refines SFAS 121's requirement that companies recognize an impairment
loss if the carrying amount of a long-lived asset is not recoverable based on
its undiscounted future cash flows and measure an impairment loss as the
difference between the carrying amount and fair value of the asset. In addition,
SFAS 144 provides guidance on accounting and disclosure issues surrounding
long-lived assets to be disposed of by sale. SFAS 144 also extends the
presentation of discontinued operations to include more disposal transactions.
SFAS 144 is effective for all fiscal quarters of all fiscal years beginning
after December 15, 2001 (January 1, 2002 for the Company). The Company's
adoption of SFAS 144 did not result in any impairment loss being recorded.

In April 2002, the FASB issued SFAS No. 145, "Rescission of FASB
Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical
Corrections" ("SFAS 145"). SFAS 145 rescinds SFAS No. 4, "Reporting Gains and
Losses from Extinguishment of Debt" ("SFAS 4"), SFAS No. 44, "Accounting for
Intangible Assets of Motor Carriers" ("SFAS 44") and SFAS No. 64,
"Extinguishments of Debt Made to Satisfy Sinking-Fund Requirements" ("SFAS 64")
and


6








QUEST DIAGNOSTICS INCORPORATED AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED
(in thousands, unless otherwise indicated)
(unaudited)


amends SFAS No. 13, "Accounting for Leases" ("SFAS 13"). This statement updates,
clarifies and simplifies existing accounting pronouncements. As a result of
rescinding SFAS 4 and SFAS 64, the criteria in APB No. 30, "Reporting the
Results of Operations-Reporting the Effects of Disposal of a Segment of a
Business, and Extraordinary, Unusual and Infrequently Occurring Events and
Transactions", will be used to classify gains and losses from extinguishment of
debt. SFAS 44 was no longer necessary because the transitions under the Motor
Carrier Act of 1980 were completed. SFAS 13 was amended to eliminate an
inconsistency between the required accounting for sale-leaseback transactions
and the required accounting for certain lease modifications that have economic
effects that are similar to sale-leaseback transactions and makes technical
corrections to existing pronouncements. The provisions of SFAS 145 are effective
for fiscal years beginning after May 15, 2002, with earlier application
encouraged. The Company expects to adopt SFAS 145 effective January 1, 2003 and
reflect any necessary reclassifications in its consolidated statements of
operations. The adoption of SFAS 145 will not have a material impact on the
Company's financial position.

In July 2002, the FASB issued SFAS No. 146, "Accounting for Costs
Associated with Exit or Disposal Activities" ("SFAS 146"), which addresses the
recognition, measurement, and reporting of costs associated with exit or
disposal activities, and supercedes Emerging Issues Task Force Issue No. 94-3,
"Liability Recognition for Certain Employee Termination Benefits and Other Costs
to Exit an Activity (including Certain Costs Incurred in a Restructuring)"
("EITF 94-3"). The principal difference between SFAS 146 and EITF 94-3 relates
to the requirements for recognition of a liability for a cost associated with an
exit or disposal activity. SFAS 146 requires that a liability for a cost
associated with an exit or disposal activity, including those related to
employee termination benefits and obligations under operating leases and other
contracts, be recognized when the liability is incurred, and not necessarily the
date of an entity's commitment to an exit plan, as under EITF 94-3. SFAS 146
also establishes that the initial measurement of a liability recognized under
SFAS 146 be based on fair value. The provisions of SFAS 146 are effective for
exit or disposal activities that are initiated after December 31, 2002, with
early application encouraged. The Company expects to adopt SFAS 146, effective
January 1, 2003.

2. ACCOUNTING FOR GOODWILL AND OTHER INTANGIBLE ASSETS

In July 2001, the FASB issued SFAS No. 142, "Goodwill and Other
Intangible Assets" ("SFAS 142"), which broadens the criteria for recording
intangible assets separate from goodwill. SFAS 142 requires the use of a
nonamortization approach to account for purchased goodwill and certain
intangibles. Under a nonamortization approach, goodwill and certain intangibles
are not amortized into results of operations, but instead are reviewed for
impairment and an impairment charge is recorded in the periods in which the
recorded carrying value of goodwill and certain intangibles is more than its
estimated fair value. The Company adopted SFAS 142 effective January 1, 2002.
The provisions of SFAS 142 require that a transitional impairment test be
performed as of the beginning of the year the statement is adopted. The
provisions of SFAS 142 also require that a goodwill impairment test be performed
annually or in the case of other events that indicate a potential impairment.
The new criteria for recording intangible assets separate from goodwill did not
require the Company to reclassify any of its intangible assets. The Company's
transitional impairment test indicated that there was no impairment of goodwill
upon adoption of SFAS 142. The annual impairment test of goodwill will be
performed at the end of the Company's fiscal year on December 31st.

Effective January 1, 2002, the Company evaluates the recoverability and
measures the possible impairment of its goodwill under SFAS 142. The impairment
test is a two-step process that begins with the estimation of the fair value of
the reporting unit. The first step screens for potential impairment and the
second step measures the amount of the impairment, if any. Management's estimate
of fair value considers publicly available information regarding the market
capitalization of the Company as well as (i) publicly available information
regarding comparable publicly-traded companies in the clinical laboratory
testing industry, (ii) the financial projections and future prospects of the
Company's business, including its growth opportunities and likely operational
improvements, and (iii) comparable sales prices, if available. As part of the
first step to assess potential impairment, management compares the estimate of
fair value for the Company to the book value of the Company's consolidated net
assets. If the book value of the consolidated net assets is greater than the
estimate of fair value, the Company would then proceed to the second step to
measure the impairment, if any. The second step compares the implied fair value
of goodwill with its carrying value. The implied fair value is determined by
allocating the fair value of the reporting unit to all of the assets and
liabilities of that unit as if the reporting unit had been acquired in a
business combination and the fair value of the reporting unit was the purchase
price paid to acquire the reporting unit. The excess of the fair value of the
reporting unit over the amounts assigned to its assets and liabilities is the
implied fair value of goodwill. If the carrying amount of the reporting unit's
goodwill is greater than its implied fair value, an impairment loss will be
recognized in the

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED
(in thousands, unless otherwise indicated)
(unaudited)


amount of the excess. Management believes its estimation methods are reasonable
and reflective of common valuation practices.

On a quarterly basis, management performs a review of the Company's
business to determine if events or changes in circumstances have occurred which
could have a material adverse effect on the fair value of the Company and its
goodwill. If such events or changes in circumstances were deemed to have
occurred, the Company would perform an impairment test of goodwill as of the end
of the quarter, consistent with the annual impairment test, and record any noted
impairment loss.

The following table presents net income and basic and diluted earnings
per common share, adjusted to reflect results as if the nonamortization
provisions of SFAS 142 had been in effect for the periods presented:

3. BUSINESS ACQUISITION

Acquisition of American Medical Laboratories, Incorporated

On April 1, 2002, the Company completed its previously announced
acquisition of all of the outstanding voting stock of American Medical
Laboratories, Incorporated, ("AML") and an affiliated company of AML, LabPortal,
Inc. ("LabPortal"), a provider of electronic connectivity products, in an
all-cash transaction with a combined value of approximately $500 million, which
included the assumption of approximately $160 million in debt.

Through the acquisition of AML, Quest Diagnostics acquired all of AML's
operations, including two full-service laboratories, 51 patient service centers,
and hospital sales, service and logistics capabilities. The all-cash purchase
price of approximately $335 million and related transaction costs, together with
the repayment of approximately $150 million of principal and related accrued
interest, representing substantially all of AML's debt, was financed by Quest
Diagnostics with cash on-hand, $300 million of borrowings under its secured
receivables credit facility and $175 million of borrowings under its unsecured
revolving credit facility. During the second and third quarters of 2002, Quest
Diagnostics repaid all of the $175 million borrowed under the Company's
unsecured revolving credit facility and $75 million borrowed under the Company's

(unaudited)


secured receivables credit facility, respectively. An additional $60 million of
the secured receivables facility was repaid on October 24, 2002.

The acquisition of AML was accounted for under the purchase method of
accounting. As such, the cost to acquire AML has been allocated on a preliminary
basis 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 AML subsequent to the closing of the acquisition.

The following table summarizes the Company's preliminary purchase price
allocation related to the acquisition of AML based on the estimated fair value
of the assets acquired and liabilities assumed on the acquisition date. The
purchase price allocation will be finalized after completion of the valuation of
certain assets and liabilities.

Based on management's review of the net assets acquired and
consultations with valuation specialists, no intangible assets meeting the
criteria under SFAS No. 141, "Business Combinations", were identified. Of the
$430 million allocated to goodwill, approximately $17 million is expected to be
deductible for tax purposes.

The following unaudited pro forma combined financial information for
the nine months ended September 30, 2002 and for the three and nine months ended
September 30, 2001 assumes that the AML acquisition was effected on January 1,
2001 (in thousands, except per share data):

Pro forma results for the nine months ended September 30, 2002 exclude
$14.5 million of non-recurring merger costs, which were incurred and expensed
by AML immediately prior to the closing of the AML acquisition.

The all-cash purchase price for LabPortal of approximately $4 million
and related transaction costs, together with the repayment of all of LabPortal's
outstanding debt of approximately $7 million and related accrued interest, was
financed by Quest Diagnostics with cash on-hand. The acquisition of LabPortal
was accounted for under the purchase method of accounting. As such, the cost to
acquire LabPortal has been allocated on a preliminary basis to the assets and
liabilities acquired based on estimated fair values as of the closing date,
including approximately $8 million of goodwill. The consolidated financial
statements include the results of operations of LabPortal subsequent to the
closing of the acquisition.

Integration of AML

During the third quarter of 2002, the Company finalized its plan
related to the integration of AML into Quest Diagnostics' laboratory network.
The plan focuses principally on improving customer service by enabling the
Company to perform esoteric testing on the east and west coasts of the United
States, and redirecting certain physician testing volumes within its national
network to provide more local testing. As part of the plan, the Company's
Chantilly, Virginia laboratory, acquired as part of the AML acquisition, will
become the primary esoteric testing laboratory and hospital service center for
the eastern United States and will complement the Company's Nichols Institute
esoteric testing facility in San Juan Capistrano, California. Esoteric testing
volumes will be redirected within the Company's national network to provide
customers with improved turnaround time and customer service. Certain routine
clinical laboratory testing currently performed in the Chantilly, Virginia
laboratory will transition over time to other testing facilities within the
Company's regional laboratory network. A reduction in staffing will occur as the
Company executes the integration plan and consolidates duplicate or overlapping
functions and facilities. Employee groups being affected as a result of this
plan include those involved in the collection and testing of specimens, as well
as administrative and other support functions.

In connection with the AML integration plan, the Company recorded $11
million of costs associated with executing the plan. The majority of these
integration costs related to employee severance and contractual obligations
associated with leased facilities and equipment. Of the total costs indicated
above, $9.5 million, related to actions that impact the employees and operations
of AML, was accounted for as a cost of the AML acquisition and included in
goodwill. Of the $9.5 million, $5.9 million related to employee severance
benefits for approximately 200 employees, with the remainder primarily related
to contractual obligations associated with leased facilities and equipment. In
addition, $1.5 million of integration costs, related to actions that impact
Quest Diagnostics' employees and operations and comprised principally of
employee severance benefits


11








QUEST DIAGNOSTICS INCORPORATED AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED
(in thousands, unless otherwise indicated)
(unaudited)


for approximately 100 employees, were accounted for as a charge to earnings in
the third quarter of 2002 and included in "other, net" within the consolidated
statements of operations. While the majority of the integration costs are
expected to be paid in 2003, there are certain severance and facility exit costs
that have payment terms extending beyond 2003.

4. PROVISION FOR SPECIAL CHARGE

During the second quarter of 2001, the Company recorded a special
charge of $6 million in connection with the refinancing of its debt and
settlement of the Company's interest rate swap agreements. Prior to the
Company's debt refinancing in June 2001, the Company's secured credit agreement
required the Company to maintain interest rate swap agreements to mitigate the
risk of changes in interest rates associated with a portion of its variable
interest rate indebtedness. These interest rate swap agreements were considered
a hedge against changes in the amount of future cash flows associated with the
interest payments of the Company's variable rate debt obligations. Accordingly,
the interest rate swap agreements were recorded at their estimated fair value in
the Company's consolidated balance sheet and the related losses on these
contracts were deferred in stockholders' equity as a component of comprehensive
income. In conjunction with the debt refinancing, the interest rate swap
agreements were terminated and the losses which were included in stockholders'
equity as a component of comprehensive income were reflected as a special charge
in the consolidated statement of operations for the nine months ended September
30, 2001.

5. EXTRAORDINARY LOSS

In conjunction with the Company's debt refinancing in the second
quarter of 2001, the Company recorded an extraordinary loss of $36 million, ($22
million, net of taxes). The loss represented the write-off of deferred financing
costs of $23 million, associated with the Company's debt which was refinanced,
and $12.8 million of payments related primarily to the tender premium incurred
in connection with the Company's cash tender offer of the Company's 10 3/4%
Senior Subordinated Notes. See Note 1,"New Accounting Standards", for a
discussion regarding the impact of SFAS 145.

6. COMMITMENTS AND CONTINGENCIES

The Company has entered into several settlement agreements with various
governmental and private payers during recent years relating to industry-wide
billing and marketing practices that had been substantially discontinued by
early 1993. In addition, the Company is aware of several pending lawsuits filed
under the qui tam provisions of the civil False Claims Act and has received
notices of private claims relating to billing issues similar to those that were
the subject of prior settlements with various governmental payers. Some of the
proceedings against the Company involve claims that are substantial in amount.
Some of the cases involve the operations of SmithKline Beecham Clinical
Laboratories, Inc. ("SBCL") prior to the closing of the SBCL acquisition.

SmithKline Beecham plc ("SmithKline Beecham") has agreed to indemnify
Quest Diagnostics, on an after-tax basis, against monetary payments for
governmental claims or investigations relating to the billing practices of SBCL
that had been settled before or were pending as of the closing date of the SBCL
acquisition. SmithKline Beecham has also agreed to indemnify the Company, on an
after-tax basis, against all monetary payments relating to professional
liability claims of SBCL for services provided prior to the closing of the SBCL
acquisition. Amounts due from SmithKline Beecham at September 30, 2002, related
principally to indemnified professional liability claims discussed above,
totaled approximately $11 million. The estimated reserves and related amounts
due from SmithKline Beecham are subject to change as additional information
regarding the outstanding claims is gathered and evaluated.

At September 30, 2002, recorded reserves relating to billing claims
approximated $10 million. Although management believes that established reserves
for both indemnified and non-indemnified claims are sufficient, it is possible
that additional information (such as the indication by the government of
criminal activity, additional tests being questioned or other changes in the
government's or private claimants' theories of wrongdoing) may become available
which may cause the final resolution of these matters to exceed established
reserves by an amount which could be material to the Company's results of
operations and cash flows in the period in which such claims are settled. The
Company does not believe that these issues will have a material adverse effect
on its overall financial condition.


12








QUEST DIAGNOSTICS INCORPORATED AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED
(in thousands, unless otherwise indicated)
(unaudited)



In addition to the billing-related settlement reserves discussed above,
the Company is involved in various legal proceedings arising in the ordinary
course of business. Some of the proceedings against the Company involve claims
that are substantial in amount. Some of these claims involve contracts of SBCL
that were terminated following the Company's acquisition of SBCL. During the
three and nine months ended September 30, 2002, the Company paid approximately
$13 million and $18 million, respectively, to settle claims related to contracts
of SBCL that were terminated following the Company's acquisition of SBCL. The
settlements had been fully reserved for. Although management cannot predict the
outcome of such proceedings or any claims made against the Company, management
does not anticipate that the ultimate outcome of the various proceedings or
claims will have a material adverse effect on the Company's financial position
but may be material to the Company's results of operations and cash flows in the
period in which such claims are resolved.

As a general matter, providers of clinical laboratory testing services
may be subject to lawsuits alleging negligence or other similar legal claims.
These suits could involve claims for substantial damages. Any professional
liability litigation could also have an adverse impact on the Company's client
base and reputation. The Company maintains various liability insurance programs
for claims that could result from providing or failing to provide clinical
laboratory testing services, including inaccurate testing results and other
exposures. The Company's insurance coverage limits its maximum exposure on
individual claims; however, the Company is essentially self-insured for a
significant portion of these claims. The basis for claims reserves incorporates
the actuarially determined projected losses based upon the Company's historical
and projected loss experience. Management believes that present insurance
coverage and reserves are sufficient to cover currently estimated exposures.
Although management cannot predict the outcome of any claims made against the
Company, management does not anticipate that the ultimate outcome of any such
proceedings or claims will have a material adverse effect on the Company's
financial position but may be material to the Company's results of operations
and cash flows in the period in which such claims are resolved.

During the nine months ended September 30, 2001, two thousand common
shares were surrendered to cover employee payroll tax withholdings related to
the exercise of stock options. For reporting purposes, these shares were
accounted for as treasury purchases which were immediately retired.

For the nine months ended September 30, 2001, other comprehensive
income included the cumulative effect of the change in accounting for derivative
financial instruments upon adoption of SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities", as amended, which reduced comprehensive
income by approximately $1 million. In addition, in conjunction with the
Company's debt refinancing, the interest rate swap agreements were terminated
and the losses which were included in stockholders' equity as a component of
comprehensive income were reflected as a special charge in the consolidated
statements of operations for the nine months ended September 30, 2001 (see
Note 4).

8. PENDING ACQUISITION

Acquisition of Unilab Corporation

On April 2, 2002, the Company entered into a definitive agreement with
Unilab Corporation ("Unilab"), which provides that Quest Diagnostics will
acquire all of the outstanding shares of Unilab common stock and assume Unilab's
existing debt of approximately $200 million. In exchange for their Unilab
shares, Unilab stockholders may elect to receive $26.50 in cash, 0.3256 shares
of Quest Diagnostics common stock or a combination of cash and stock. The
aggregate amount of cash available to Unilab stockholders will be limited to 30%
of the total consideration available for the Unilab shares. Unilab has
approximately 37.4 million shares of common stock outstanding on a fully diluted
basis. If


14








QUEST DIAGNOSTICS INCORPORATED AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - CONTINUED
(in thousands, unless otherwise indicated)
(unaudited)


Unilab stockholders elect to receive 30% of the consideration in cash and if all
options are exercised, Quest Diagnostics would issue approximately 8.5 million
shares and pay $297 million in cash to the stockholders of Unilab. If Unilab
stockholders elect to receive 100% of the consideration in Quest Diagnostics
common stock and all Unilab options were exercised, Quest Diagnostics would
issue approximately 12.2 million common shares to the stockholders of Unilab.
The transaction, which has been approved by the Boards of Directors of both
companies, is subject to the satisfaction of customary conditions, including the
tender of a majority of Unilab's common stock on a fully diluted basis, and
regulatory review.

During the second quarter of 2002, the Company and Unilab received a
request for additional information (commonly referred to as a "second request")
from the Federal Trade Commission ("FTC") under the Hart-Scott-Rodino Antitrust
Improvements Act (the "HSR Act") in connection with the Company's pending
acquisition of Unilab. The Company and Unilab are continuing their discussions
with the FTC regarding the proposed transaction, including settlement
discussions, and the process is taking longer than anticipated. During the third
quarter of 2002, the Company and Unilab extended the termination date of their
merger agreement to November 30, 2002. All other provisions of the agreement
remain in effect. The completion of the transaction is subject to completion of
the HSR process and satisfaction of the other conditions to the cash election
exchange offer and the agreement and plan of merger. The Company continues to
believe that the transaction is not anti-competitive, and hopes to close the
transaction in the fourth quarter of 2002.

As part of the acquisition, Quest Diagnostics would acquire all of
Unilab's operations, including its primary testing facilities in Los Angeles,
San Jose and Sacramento, California, its more than 400 regional service and
testing facilities located throughout California and its operations in Arizona.
The Company expects to finance the cash portion of the purchase price and any
retirements of Unilab's existing debt with the proceeds from a new $450 million
five-year amortizing term loan commitment, which is available for the
acquisition of Unilab, available borrowings under its unsecured revolving credit
facility and its secured receivables credit facility and cash on-hand. The term
loan, which is contingent upon the completion of the Unilab transaction, will
carry interest at LIBOR plus 1.3125% and require principal repayments of the
initial amount borrowed equal to 15%, 20%, 20%, 20% and 25% in years one through
five, respectively. Effective September 20, 2002, the term loan commitment was
amended to extend the maturity of the commitment from September 30, 2002 to
December 31, 2002. Since the transaction has yet to close, a preliminary
purchase price allocation is not practical at this time.

9. SUMMARIZED FINANCIAL INFORMATION

The Company's 6 3/4% senior notes due 2006, 7 1/2% senior notes due
2011 and 1 3/4% contingent convertible debentures due 2021 are guaranteed by
each of the Company's wholly owned subsidiaries that operate clinical
laboratories in the United States (the "Subsidiary Guarantors"). With the
exception of Quest Diagnostics Receivables Incorporated (see paragraph below),
the non-guarantor subsidiaries are primarily foreign and less than wholly owned
subsidiaries.

In conjunction with the Company's receivables financing in July 2000,
the Company formed a new wholly owned non-guarantor subsidiary, Quest
Diagnostics Receivables Incorporated ("QDRI"). The Company and the Subsidiary
Guarantors, with the exception of AML, transfer all private domestic receivables
(principally excluding receivables due from Medicare, Medicaid and other federal
programs, and receivables due from customers of its joint ventures) to QDRI.
QDRI utilizes the transferred receivables to collateralize the Company's secured
receivables credit facility. The Company and the Subsidiary Guarantors provide
collection services to QDRI. QDRI uses cash collections principally to purchase
new receivables from the Company and the Subsidiary Guarantors.

The following condensed consolidating financial data illustrates the
composition of the combined guarantors. Investments in subsidiaries are
accounted for by the parent using the equity method for purposes of the
supplemental consolidating presentation. Earnings (losses) of subsidiaries are
therefore reflected in the parent's investment accounts and earnings. The
principal elimination entries relate to investments in subsidiaries and
intercompany balances and transactions. On April 1, 2002, Quest Diagnostics
acquired AML (see Note 3), which has been included in the accompanying condensed
consolidating financial data, subsequent to the closing of the acquisition, as a
Subsidiary Guarantor.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations

Critical Accounting Policies

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires us to make estimates
and assumptions and select accounting policies that affect the reported amounts
of assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements, as well as the reported amounts of
revenues and expenses during the reporting period. Actual results could differ
from those estimates.

While many operational aspects of our business are subject to complex
federal, state and local regulations, the accounting for our business is
generally straightforward with net revenues primarily recognized upon completion
of the testing process. Our revenues are primarily comprised of a high volume of
relatively low dollar transactions, and about half of all our costs and expenses
consist of employee compensation and benefits. Due to the nature of our
business, several of our accounting policies involve significant estimates and
judgments. These accounting policies have been described in our 2001 Annual
Report on Form 10-K, with the following accounting policy adopted effective
January 1, 2002:

Accounting for and recoverability of goodwill

In July 2001, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 142, "Goodwill and
Other Intangible Assets" ("SFAS 142"). The impact of adopting SFAS 142 is
summarized in Note 2 to the interim consolidated financial statements.

Effective January 1, 2002, we evaluate the recoverability and measure
the possible impairment of our goodwill under SFAS 142. The impairment test is a
two-step process that begins with the estimation of the fair value of the
reporting unit. The first step screens for potential impairment and the second
step measures the amount of the impairment, if any. Our estimate of fair value
considers publicly available information regarding the market capitalization of
our Company, as well as (i) publicly available information regarding comparable
publicly-traded companies in the clinical laboratory testing industry, (ii) the
financial projections and future prospects of our business, including its growth
opportunities and likely operational improvements, and (iii) comparable sales
prices, if available. As part of the first step to assess potential impairment,
we compare our estimate of fair value for the Company to the book value of our
consolidated net assets. If the book value of our consolidated net assets is
greater than our estimate of fair value, we would then proceed to the second
step to measure the impairment, if any. The second step compares the implied
fair value of goodwill with its carrying value. The implied fair value is
determined by allocating the fair value of the reporting unit to all of the
assets and liabilities of that unit as if the reporting unit had been acquired
in a business combination and the fair value of the reporting unit was the
purchase price paid to acquire the reporting unit. The excess of the fair value
of the reporting unit over the amounts assigned to its assets and liabilities is
the implied fair value of goodwill. If the carrying amount of the reporting unit
goodwill is greater than its implied fair value, an impairment loss will be
recognized in the amount of the excess. We believe our estimation methods are
reasonable and reflective of common valuation practices.

On a quarterly basis, we perform a review of our business to determine
if events or changes in circumstances have occurred which could have a material
adverse effect on the fair value of the Company and its goodwill. If such events
or changes in circumstances were deemed to have occurred, we would perform an
impairment test of goodwill as of the end of the quarter, consistent with the
annual impairment test, and record any noted impairment loss.

Integration of Acquired Businesses

American Medical Laboratories, Incorporated

On April 1, 2002, we completed our previously announced acquisition of
all of the outstanding voting stock of American Medical Laboratories,
Incorporated, ("AML"). See Note 3 to the interim consolidated financial
statements for a full discussion of this transaction.

During the third quarter of 2002, we finalized our plan related to the
integration of AML into our laboratory network. The plan focuses principally on
improving customer service by enabling us to perform esoteric testing on the
east and west coasts of the United States, and redirecting certain physician
testing volumes within our national network to provide more local testing. As
part of the plan, our Chantilly, Virginia laboratory, acquired as part of the
AML acquisition, will become our primary esoteric testing laboratory and
hospital service center for the eastern United States and will complement our
Nichols Institute esoteric testing facility in San Juan Capistrano, California.
Esoteric testing volumes will be redirected


19








within our national network to provide customers with improved turnaround time
and customer service. Certain routine clinical laboratory testing currently
performed in our Chantilly, Virginia laboratory will transition over time to
other testing facilities within our regional laboratory network. A reduction in
staffing will occur as we execute the integration plan and consolidate duplicate
or overlapping functions and facilities. Employee groups being affected as a
result of this plan include those involved in the collection and testing of
specimens, as well as administrative and other support functions.

In connection with the AML integration plan, we recorded $11 million of
costs associated with executing the plan. The majority of these integration
costs related to employee severance and contractual obligations associated with
leased facilities and equipment. Of the total costs indicated above, $9.5
million, related to actions that impact the employees and operations of AML, was
accounted for as a cost of the AML acquisition and included in goodwill. Of the
$9.5 million, $5.9 million related to employee severance benefits for
approximately 200 employees, with the remainder primarily related to contractual
obligations associated with leased facilities and equipment. In addition, $1.5
million of integration costs, related to actions that impact Quest Diagnostics'
employees and operations and comprised principally of employee severance
benefits for approximately 100 employees, were accounted for as a charge to
earnings in the third quarter of 2002 and included in "other, net" within the
consolidated statements of operations. While the majority of the integration
costs are expected to be paid in 2003, there are certain severance and facility
exit costs that have payment terms extending beyond 2003. We plan to fund the
costs to integrate AML through cash from operations. Upon completion of the AML
integration, we expect to realize approximately $15 million of annual synergies
and we expect to achieve this annual rate of synergies by the end of 2003.

Unilab Corporation

On April 2, 2002, we entered into a definitive agreement with Unilab
Corporation ("Unilab"), which provides that we will acquire all of the
outstanding shares of Unilab common stock. See Note 8 to the interim
consolidated financial statements for a full discussion of this transaction.

We hope to close the transaction in the fourth quarter of 2002, and
estimate that we will incur up to $20 million of costs to integrate Quest
Diagnostics and Unilab. A significant portion of these costs is expected to
require cash outlays and is expected to primarily relate to severance and other
integration-related costs during 2003, including the elimination of excess
capacity and workforce reductions. These estimates are preliminary and will be
subject to revisions as integration plans are developed and finalized. To the
extent that the costs relate to actions that impact the employees and operations
of Unilab, such costs will be accounted for as a cost of the Unilab acquisition
and included in goodwill. To the extent that the costs relate to actions that
impact Quest Diagnostics' employees and operations, such costs will be accounted
for as a charge to earnings in the period that the integration plans are
approved and communicated. We hope to finalize and record these costs during the
fourth quarter of 2002.

Results of Operations

Three and Nine months ended September 30, 2002 Compared with Three and
Nine months ended September 30, 2001

Reported net income for the three months ended September 30, 2002
increased to $87 million from $50 million for the prior year period. Net income
for the three months ended September 30, 2002 increased by $28 million, or 47%,
from $59 million for the three months ended September 30, 2001, assuming that
the nonamortization provisions of SFAS 142 had been in effect in 2001. This
increase in earnings was primarily attributable to revenue growth, driven by
improvements in clinical testing volume and average revenue per requisition,
and improved efficiencies generated from our Six Sigma and Standardization
initiatives, partially offset by increases in employee compensation and
supply costs, depreciation expense and investments in our information
technology strategy and strategic growth opportunities. In addition, we
estimate that the September 11th, 2001 national tragedy reduced our net
revenues for the third quarter of 2001 by approximately $8 million, or 1%
of net revenues, and reduced net income during the third quarter of 2001
by approximately $3 million.

Reported net income for the nine months ended September 30, 2002
increased to $240 million from $111 million for the prior year period. Assuming
that the nonamortization provisions of SFAS 142 had been in effect in 2001, net
income for the nine months ended September 30, 2001 would have been $138
million. In addition, results for the nine months ended September 30, 2001
included an extraordinary loss of $36 million ($22 million, net of taxes) and a
special charge of $6.0 million ($3.6 million, net of taxes), both of which were
incurred in conjunction with our debt refinancing in the second quarter of 2001.
Assuming that SFAS 142 had been in effect during 2001, and excluding the
extraordinary loss and special charge in 2001, income for the nine months ended
September 30, 2002 increased by $77 million, compared to the prior year period,
an


20








increase of 47%. This increase in earnings was primarily attributable to revenue
growth, driven by improvements in clinical testing volume and average revenue
per requisition, improved efficiencies generated from our Six Sigma and
Standardization initiatives, and a reduction in net interest expense, partially
offset by increases in employee compensation and supply costs, depreciation
expense and investments in our information technology strategy and strategic
growth opportunities.

Net Revenues

Net revenues for the three and nine months ended September 30, 2002
grew by 17.2% and 13.1%, respectively, compared to the prior year period. The
acquisition of AML, which was completed on April 1, 2002, contributed
approximately 55% and 45% to the increase in net revenues for the three and nine
months ended September 30, 2002. For the three and nine months ended September
30, 2002, clinical testing volume, measured by the number of requisitions,
increased 13.7% and 9.4%, respectively, compared to the prior year period.
Assuming AML had been part of Quest Diagnostics in 2001, clinical testing volume
would have increased above the prior year levels by 5.0% and 4.0%, respectively,
on a pro forma basis, for the three and nine months ended September 30, 2002.
Our clinical testing volume and revenue comparisons to the prior year were
impacted by the events of September 11th, 2001, and reduced revenues by
approximately $8 million and requisition volume by approximately 1% during the
third quarter of 2001. We continue to see strong growth in our gene-based and
esoteric testing with gene-based testing revenues growing at more than 20%,
compared to the prior year. Our drugs-of-abuse testing business which accounted
for approximately 8% of our volume and 4% of our revenues, remained essentially
flat during the third quarter of 2002, compared to the prior year period. This
is a significant improvement from the 9% year-over-year volume decline
experienced in the second quarter of 2002, which had the impact of reducing
total company volume by approximately 1%. The improvement is the result of a
temporary increase in drug screenings for potential candidates for newly created
airport security positions within the Federal Aviation Administration ("FAA").
The additional volume from the FAA is expected to scale back to normal levels
early in the fourth quarter of 2002. Average revenue per requisition increased
2.9% and 3.1%, respectively, for the three and nine months ended September 30,
2002, compared to the prior year period. The improvement in average revenue per
requisition was primarily attributable to a continuing shift in test mix to
higher value testing, including gene-based testing, which contributed more than
half of the improvement, and a shift in payer mix to higher priced
fee-for-service reimbursement.

Operating Costs and Expenses

Total operating costs for the three and nine months ended September 30,
2002 increased $111 million and $247 million, respectively, from the prior year
period primarily due to increases in our clinical testing volume, largely as a
result of the AML acquisition, employee compensation and supply costs and
depreciation expense; partially offset by a reduction in bad debt expense. While
our cost structure has been favorably impacted by the synergies realized as a
result of the integration of SmithKline Beecham Clinical Laboratories, Inc.
("SBCL") and the improved efficiencies generated from our Six Sigma and
Standardization initiatives, we continue to make investments to enhance our
infrastructure to pursue our overall business strategy. These investments
include those related to:

o Skills training for all employees, which together with our
competitive pay and benefits, helps to increase employee
satisfaction and performance, which we believe will result in
better service to our customers;

o Our information technology strategy, which is designed to result
in better service to our customers; and

o Our strategic growth opportunities.

Cost of services, which includes the costs of obtaining, transporting
and testing specimens was 59.0% of net revenues for the three months ended
September 30, 2002, decreasing from 59.3% in the prior year period. For the nine
months ended September 30, 2002, costs of services, as a percentage of net
revenues, decreased to 59.0% from 59.4% a year ago. The positive impact of our
Six Sigma and Standardization efforts and the increase in average revenue per
requisition, which reduced cost of services as a percentage of net revenues, was
partially offset by the addition of AML's higher cost of services as of April 1,
2002.

Selling, general and administrative expenses, which include the costs
of the sales force, billing operations, bad debt expense and general management
and administrative support, decreased during the three months ended September
30, 2002 as a percentage of net revenues to 25.7% from 27.8% in the prior year
period. For the nine months ended September 30, 2002, selling, general and
administrative expenses decreased as a percentage of net revenues to 26.3% from
28.0% in the prior year period. These decreases were primarily due to
efficiencies from our Six Sigma and Standardization efforts, in particular bad
debt expense, the improvement in average revenue per requisition and the
addition of AML's cost structure as


21








of April 1, 2002. During the third quarter of 2002, bad debt expense improved to
5.1% of net revenues, compared to 6.1% of net revenues a year ago. For the nine
months ended September 30, 2002, bad debt expense was 5.4% of net revenues,
compared to 6.1% of net revenues in the prior year. The improvements in bad debt
expense were principally attributable to the continued progress that we have
made in our overall collection experience through process improvements, driven
by our Six Sigma and Standardization initiatives. These improvements primarily
relate to the collection of diagnosis, patient and insurance information
necessary to effectively bill for services performed. We believe that our Six
Sigma and Standardization initiatives will provide additional opportunities to
further improve our overall collection experience.

Interest, Net

Net interest expense for the three and nine months ended September 30,
2002 decreased from the prior year periods by $1.4 million and $17.0 million,
respectively. For the three months ended September 30, 2002, the reduction was
primarily due to a favorable interest rate environment, compared to the prior
year period. For the nine months ended September 30, 2002, the reduction was
primarily due to the favorable impact of our debt refinancings in 2001 and a
favorable interest rate environment.

Amortization of Goodwill and Other Intangible Assets

Amortization of goodwill and other intangible assets for the three and
nine months ended September 30, 2002 decreased from the prior year period by
$9.4 million and $28 million, respectively, principally as the result of
adopting SFAS 142, effective January 1, 2002. See Note 2 to the interim
consolidated financial statements for further details regarding the impact of
SFAS 142.

Provision for Special Charge

During the second quarter of 2001, we recorded a special charge of $6
million in connection with the refinancing of our debt and settlement of our
interest rate swap agreements. Prior to our debt refinancing in June 2001, our
secured credit agreement required us to maintain interest rate swap agreements
to mitigate the risk of changes in interest rates associated with a portion of
our variable interest rate indebtedness. These interest rate swap agreements
were considered a hedge against changes in the amount of future cash flows
associated with the interest payments of our variable rate debt obligations.
Accordingly, the interest rate swap agreements were recorded at their estimated
fair value in our consolidated balance sheet and the related losses on these
contracts were deferred in stockholders' equity as a component of comprehensive
income. In conjunction with the debt refinancing, the interest rate swap
agreements were terminated and the losses, which were reflected in stockholders'
equity as a component of comprehensive income, were reflected as a special
charge in the consolidated statement of operations for the nine months ended
September 30, 2001.

Minority Share of Income

Minority share of income for the three and nine months ended September
30, 2002 increased from the prior year level, primarily due to the improved
performance of our consolidated joint ventures.

Other, Net

"Other, net", which represents income for each of the periods
presented, and includes equity earnings from our unconsolidated joint ventures
and miscellaneous gains and losses, increased $1.7 million and $6.9 million, for
the three and nine months ended September 30, 2002, respectively. For the
three-month period, the increase was primarily due to a $3.8 million gain on an
investment, partially offset by a $1.5 million charge associated with the
integration of AML, both of which were recorded in the third quarter of 2002.
For the nine-month period, the increase was principally due to improved
operating performance at our unconsolidated joint ventures, which generated an
increase of $4.0 million in equity earnings. The nine-month period of 2001
reflects the net impact of writing off $7.0 million of impaired assets,
partially offset by a $6.3 million gain on the sale of an investment.

Income Taxes

During 2001, our effective tax rate was significantly impacted by
goodwill amortization, the majority of which was not deductible for tax
purposes, and had the effect of increasing the overall tax rate. The reduction
in the effective tax rate for


22








the three and nine months ended September 30, 2002 was primarily due to the
reduction in amortization of goodwill (as a result of adopting SFAS 142,
effective January 1, 2002) the majority of which was not deductible for tax
purposes.

Extraordinary Loss

In conjunction with our debt refinancing in the second quarter of 2001,
we recorded an extraordinary loss of $36 million, ($22 million, net of taxes).
The loss represented the write-off of deferred financing costs of $23 million,
associated with our debt which was refinanced, and $12.8 million of payments
related primarily to the tender premium incurred in connection with our cash
tender offer of our 10 3/4% senior subordinated notes due 2006 (the
"Subordinated Notes").

EBITDA

EBITDA represents income before net interest expense, income taxes,
depreciation and amortization, and special items in 2001. The special items
represented the extraordinary loss and the special charge associated with our
debt refinancing in the second quarter of 2001. EBITDA is presented and
discussed because management believes it is a useful adjunct to net income and
other measurements under accounting principles generally accepted in the United
States since it is a meaningful measure of a company's performance and ability
to meet its future debt service requirements, fund capital expenditures and meet
working capital requirements. EBITDA is not a measure of financial performance
under accounting principles generally accepted in the United States and should
not be considered as an alternative to (i) net income (or any other measure of
performance under accounting principles generally accepted in the United States)
as a measure of performance or (ii) cash flows from operating, investing or
financing activities as an indicator of cash flows or as a measure of liquidity.

EBITDA for the three months ended September 30, 2002 improved to $192
million, or 18.2% of net revenues, from $142 million, or 15.7% of net revenues,
in 2001. For the nine months ended September 30, 2002, EBITDA improved to $543
million, or 17.7% of net revenues, from $413 million, or 15.2% of net revenues,
in 2001. The increases in EBITDA were primarily due to revenue growth, driven by
improvements in clinical testing volume and average revenue per requisition, and
improved efficiencies generated from our Six Sigma and Standardization
initiatives, partially offset by increases in employee compensation and supply
costs, and investments in our information technology strategy and strategic
growth opportunities. The improvements in EBITDA as a percentage of net revenues
were also driven by these same factors and were partially offset by the
acquisition of AML, which had EBITDA percentages lower than those of Quest
Diagnostics.

Impact of Contingent Convertible Debentures on Diluted Earnings per
Common Share

On November 26, 2001, we completed our $250 million offering of 1 3/4%
contingent convertible debentures due 2021 (the "Debentures"). Each one thousand
dollar principal amount of Debentures is convertible into 11.429 shares of our
common stock, which represents an initial conversion price of $87.50 per share.
Holders may surrender the Debentures for conversion into shares of our common
stock under any of the following circumstances: (i) if the sales price of our
common stock is above 120% of the conversion price (or $105 per share) for
specified periods; (ii) if we call the Debentures or (iii) if specified
corporate transactions have occurred. See Note 12 to the Consolidated Financial
Statements contained in our 2001 Annual Report on Form 10-K for a further
discussion of the Debentures.

The if-converted method is used in determining the dilutive effect of
the Debentures in periods when the holders of such securities are permitted to
exercise their conversion rights. As of and for the three and nine months ended
September 30, 2002, the holders of our Debentures did not have the ability to
exercise their conversion rights. Had the requirements to allow the holders to
exercise their conversion rights been met and the Debentures remained
outstanding for the entire period, diluted earnings per common share would have
been reduced by approximately 2% during the quarter and nine months ended
September 30, 2002.

Quantitative and Qualitative Disclosures About Market Risk

We address our exposure to market risks, principally the market risk of
changes in interest rates, through a controlled program of risk management that
may include the use of derivative financial instruments. We do not hold or issue
derivative financial instruments for trading purposes. We do not believe that
our foreign exchange exposure is material to our financial position or results
of operations taken as a whole. See Note 2 to the Consolidated Financial
Statements contained in our 2001 Annual Report on Form 10-K for additional
discussion of our financial instruments and hedging activities.

At September 30, 2002 and December 31, 2001, the fair value of our debt
was estimated at approximately $1.1 billion and $857 million, respectively,
using quoted market prices and yields for the same or similar types of
borrowings, taking into account the underlying terms of the debt instruments. At
September 30, 2002 and December 31, 2001, the estimated fair value exceeded the
carrying value of the debt by approximately $78 million and $35 million,
respectively. An assumed 10% increase in interest rates (representing
approximately 50 basis points) would potentially reduce the estimated fair value
of our debt by approximately $10 million and $26 million at September 30, 2002
and December 31, 2001, respectively.

Our Debentures have a contingent interest component that will require
us to pay contingent interest based on certain thresholds, as outlined in the
Indenture. The contingent interest component, which is more fully described in
Note 12 to the Consolidated Financial Statements contained in our 2001 Annual
Report on Form 10-K, is considered to be a derivative instrument subject to SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities", as
amended. As such, the derivative was recorded at its fair value in the
consolidated balance sheet and was not material at September 30, 2002 and
December 31, 2001.

Borrowings under our unsecured revolving credit facility under our
Credit Agreement and our secured receivables credit facility are subject to
variable interest rates. Interest rates on our unsecured revolving credit
facility are also subject to a pricing schedule that fluctuates over an
approximate range of 50 basis points, based on changes in our credit rating. As
such, our borrowing cost under these credit facilities will be subject to both
fluctuations in interest rates and changes in our c
