PART I

Item 1. Business

General

Covance Inc. is a leading drug development services company providing a wide range of early-stage and late-stage product development
services
on a worldwide basis primarily to the pharmaceutical, biotechnology and medical device industries. We also provide laboratory testing services to the chemical, agrochemical and food industries. We
believe Covance is one of the world's largest drug development services companies, based on annual net revenues, and one of a few that are capable of providing comprehensive global product development
services. Covance maintains offices in more than 20 countries.

Business Strategy

Drug development services companies like Covance typically derive substantially all of their revenue from the research, development and
marketing expenditures of
the pharmaceutical, biotechnology and medical device industries. We believe outsourcing of these services has increased in the past and may increase in the
future because of several factors, including: pressures to contain costs, limitations on internal capacity, the need for faster development time for new drugs, research in multiple countries
simultaneously, stringent government regulation, and expertise that customers lack internally. We believe the investment and amount of time required to develop new drugs has been increasing, and that
these trends create opportunities for companies that can help make the process of drug development more efficient.

Our
strategy is to provide services that will generate high quality and timely data in support of new drug approval or use expansion. We do this by developing and delivering innovative
high quality services that apply science and technology and global reach to capture, manage and integrate a vast array of drug development data. In certain service areas, such as toxicology, an
increasing portion of our business is being provided through strategic, dedicated laboratory testing services contracts, in which our clients commit to purchasing a specific dollar amount of services
in exchange for guaranteed access to a portion of our facilities. This arrangement benefits our customers by guaranteeing them long-term capacity and infrastructure to run their
preclinical studies, and benefits Covance by allowing us to more efficiently utilize our capacity and resources.

Operational Excellence.Our goal is to deliver consistently outstanding service to our
clients on a global scale through our
platform focused on people, process and clients. As a scientific services company, people are integral to our success. We work to recruit, develop and retain talented people through our "Compelling
Offer" program that is designed to provide and encourage highly qualified people to initiate and build a career at Covance. We aim to enhance the effectiveness of these people with superior processes
to efficiently deliver a high level of client service. Among other tools, we use Six Sigma® to optimize our processes to increase our cost competitiveness, eliminate variability in our
client service levels and build competitive advantage. Finally, we seek to leverage consistently outstanding client service to build strategic relationships with our clients that drive growth and help
sustain the competitive advantage we achieve. Across our People, Process and Clients platform, we seek to utilize technology to augment the talent of our people, to automate robust processes, and to
link us more closely to our clients via proprietary systems such as StudyTracker®, LabLink and Trial Tracker®.

Global Reach.We believe that it is important to provide a broad range of drug research
and development services on a global
basis. We have offices, regional monitoring sites and laboratories in over 35 locations in more than 20 different countries and conduct field work in many other countries. We believe we are a leader
among drug development services companies in our ability to deliver services globally.

Acquisitions.In addition to internal development of services, we consider strategic
acquisitions that are complementary to
our existing services and that expand our ability to serve our clients. While we cannot

1

---



exclude
the possibility that we may opportunistically seek to take advantage of other situations, we generally expect acquisitions to enhance our existing services either qualitatively or
geographically or to add new services that can be integrated with our existing services. In 2006 and 2005, we enhanced our preclinical pharmacology service offering with the acquisitions of Radiant
Research Inc. ("Radiant") and GFI Clinical Services ("GFI"), and enhanced our research products antibody services offering with the acquisition of Signet Laboratories, Inc. ("Signet").

Services

The services we provide constitute two segments for financial reporting purposes: (1) early development services, which includes
preclinical services and
clinical pharmacology services, and (2) late-stage development services, which includes central laboratory, clinical development, cardiac safety, periapproval, and market access
services. Although each segment has separate services within it, they can be and increasingly are combined in integrated service offerings and we believe clients increasingly are interested in the
opportunities for such combined services.

Early Development

Preclinical Services

Our preclinical services include toxicology services and pharmaceutical chemistry and related services. Our preclinical area has been a
source of innovation by
introducing new technologies for client access to data such as StudyTracker®, electronic animal identification, multimedia study reports and animal and test tube measures of induced cell
proliferation or reproduction. Study Tracker is an internet-based client access product which allows customers of toxicology, bioanalytical, metabolism and reproductive and developmental toxicology
services to review study data and schedules on a near real-time basis. We have laboratories in locations which include Madison, Wisconsin and Vienna, Virginia in the United States and
Harrogate, United Kingdom and Muenster, Germany in Europe. We also have bioanalytical laboratories in the United States in Indianapolis, Indiana and Chantilly, Virginia, and an administrative and
sales office in Tokyo, Japan. In 2002, we completed a significant expansion of our Madison, Wisconsin facility and in 2003 we expanded our Harrogate, United Kingdom facility. In 2004, we announced
major expansions to each of our Madison, Wisconsin and Harrogate, United Kingdom facilities. The Harrogate expansion opened for studies in the fourth quarter of 2005 and in Madison the new expansion
was brought online in the first quarter of 2006.

Toxicology.Our preclinical toxicology services includein
vivotoxicology
studies, which are studies of the effects of drugs in animals, and genetic toxicology studies, which include studies of the effects of drugs on chromosomes, as well as on genetically modified mice. We
offer immunotoxicology services in which we assess the impact of drugs or chemicals on the structure and function of the immune system. Our immunotoxicology and cell culture laboratory features online
data capture capabilities and instrumentation monitoring systems that are designed to be compliant with Good Laboratory Practices.

Pharmaceutical Chemistry.In our pharmaceutical chemistry services, we determine the
metabolic profile and bioavailability
of drug candidates. We also provide laboratory testing services to the chemical, agricultural chemical and food industries. We offer a complete range of services to agricultural chemical manufacturers
to determine the potential risk to humans, animals and the environment from plant protection products such as pesticides. We also offer a broad range of services to the food and nutriceutical
industries, including nutritional analysis and nutritional content fact labels.

Research Products.We provide custom polyclonal and monoclonal antibody services for
research purposes and
purpose-bred animals for biomedical research. In May 2006, we expanded our offerings in monoclonal antibodies with the purchase of Signet of Dedham, Massachusetts, for cash payments
totaling $9.1 million. Signet was a leading provider of monoclonal antibodies used in the research of cancer, and infectious and other diseases. The purpose-bred research animals we
provide are required by pharmaceutical and biotechnology companies, university research centers and contract research organizations as part of

2

---



required
preclinical animal safety and efficacy testing. Through a variety of processes, technology and specifically constructed facilities, we provide purpose-bred,
pre-acclimated and specific pathogen free animals that meet our clients' rigorous quality control requirements.

Bioanalytical Services.Our bioanalytical testing service, which is conducted in our
bioanalytical laboratory in
Indianapolis, Indiana and in our immunoanalytical facility in Chantilly, Virginia, as well as in Madison, Wisconsin and Harrogate, United Kingdom, helps determine the appropriate dose and frequency of
drug application from late discovery evaluation through Phase III clinical testing on a full-scale, globally integrated basis.

Clinical Pharmacology Services

We provide clinical pharmacology services, including first-in-human trials, of new pharmaceuticals at our ten sites located throughout
the United States and our one site in Leeds, United Kingdom, and also offer our clients access to specialized patient populations needed for Phase II trials in specific therapeutic areas. We have
grown this service offering recently through acquisitions. In 2006, we significantly expanded our capacity and capabilities in the United States with the acquisition of Radiant's eight sites and its
access to specialized patient populations, for cash payments totaling $66.6 million. In 2005, we acquired GFI for cash payments totaling $6.2 million.

Late-Stage Development

Central Laboratory Services

We are the largest global central laboratory in the world. We have three central laboratories, one in each of the United States,
Switzerland and Singapore that
provide central laboratory services, including biomarker services, to biotechnology and pharmaceutical customers. We also have a contractual arrangement with a leading Australian laboratory. In
January 2007, we announced that we are building a central laboratory in Shanghai, China which we anticipate will open in late 2007.

Our
capabilities provide clients the flexibility to conduct studies on a multinational and simultaneous basis. The data we provide is combinable because we use consistent laboratory
methods, the same reagent manufacturers and identical equipment calibration and clinical trial reference ranges. Combinable data eliminates the cumbersome process of statistically correlating results
generated using different methods and different laboratories on different equipment.

We
also employ a proprietary clinical trials management system that enables us to enter a sponsor's protocol requirements directly into our database. The laboratory data can be audited
because all laboratory data can be traced to source documents. In addition, the laboratories are capable of delivering customized data electronically within 24 hours of test completion. Covance
also offers pharmacogenomic testing and sample storage technologies in conjunction with our central laboratory services. Central Laboratory Services also offers LabLink, an internet-based client
access program that allows customers to review and query clinical trial lab data on a near real-time basis, and Covance Local Central Laboratories, which uses a proprietary system to
harmonize laboratory results from local and regional laboratories to help expand the reach of traditional central laboratory services.

Our
central laboratories have an automated kit production line that is located in the United States and supplies kits to investigator sites around the world. This system allows the
flexibility to expand kit production volume more quickly and uses consistent methods to reduce supply variation for our customers.

Clinical Development Services

We offer a comprehensive range of clinical trial services, including the full management of Phase II and III clinical studies. We have
extensive experience in a
number of therapeutic areas, and we provide the

3

---



following
core services either on an individual or aggregated basis to meet clients' needs: Study Design and Modeling; Study Orchestration; Trial Logistics; Enablement of Study Site Performance;
Clinical Data Management and Biostatistical Analysis; and Medical Writing and Regulatory Services.

We
have extensive experience in managing clinical trials in North America, Europe, Latin America, and Asia Pacific. These trials may be conducted separately or simultaneously as part of
a multinational development plan. We can manage every aspect of clinical trials from clinical development plans and protocol design to New Drug Applications, among other supporting services. In 2006,
Clinical Development Services continued its expansion into Eastern Europe and Asia Pacific.

Clinical
Development Services utilizes Trial Tracker®, a web-enabled clinical trial project management and tracking tool which allows both our employees and
customers to review and manage all aspects of clinical trial projects. We have also integrated the management of clinical data across our Phase I through IV clinical services using the
Oracle® clinical platform.

Clinical Trial Support Services

Cardiac Safety Services.Our ability to collect and centralize clinical trial data is
enhanced by our cardiac safety service
offerings which include the capture and interpretation of electrocardiograms. Electrocardiogram analysis, one of the most frequently used tools in clinical trials, is included in more than
one-half of clinical trials as part of the study protocol. We distribute a proprietary hand-held electrocardiogram device to clinical trial sites. The device, which can be used
anywhere in the world, collects the data, performs a real-time quality check, and transmits the information by telephone to a full-time central operations center where
cardiologists read the results. Covance offers ambulatory cardiac monitoring capabilities, often referred to as Holter monitoring. Holter monitoring involves the ambulatory monitoring of cardiac
activity and permits long-term monitoringoften 24 to 48 hours as opposed to the ten seconds of data typically provided by stationary ECGs, and therefore may reveal
certain conditions which may not be discovered by a stationary ECG.

Cardiac
Safety Services operates a centralized imaging center to meet a growing pharmaceutical industry need for imaging to document clinical efficacy and safety. We offer our clients
Digitography, a patented system for use in clinical trials which allows on screen digital ECG waveform measurement with resolution which we believe is on par with the best in the
industry.

Interactive Voice Response Services.To expedite the drug development process and to
help reduce costs, we created a
proprietary interactive trial management system. This system uses touch-tone telephone technology for data entry purposes and assists our clients in managing clinical trials on a
real-time basis and in reducing product waste with just-in-time inventory processing. This system, which is multi-lingual, is available world-wide
through toll-free numbers 24 hours per day, seven days per week. The most frequently used functions include patient screening, patient enrollment, patient randomization, drug
assignments, drug inventory management, unblinding, discontinuations and patient diaries. We offer this system both in conjunction with clinical trials we conduct and as a stand-alone service.

Commercialization Services

Periapproval Services.Periapproval trials are studies conducted "around the time of NDA
approval", generally after a drug
has successfully undergone clinical efficacy and safety testing and the New Drug Application has been submitted to the Food and Drug Administration ("FDA"). We offer a range of periapproval services,
including: Treatment Investigational New Drug applications; Phase IIIb clinical studies, which involve studies conducted after New Drug Application submission, but before regulatory approval is
obtained; Phase IV clinical studies which are studies conducted after initial approval of the drug; and other types of periapproval studies such as post-marketing surveillance studies, FDA
mandated post-marketing commitments generally focusing on characterizing a drug's safety in large, diverse patient groups, product withdrawal support services and prescription to
over-the-counter switch studies.

Market Access Services.We offer a wide range of reimbursement and healthcare economics
consulting services, including
outcomes and pharmacoeconomic studies, reimbursement planning, reimbursement advocacy programs and registry services. Pharmaceutical, biotechnology and medical device manufacturers purchase these
services from us to help optimize their return on research and development investments. We offer InTeleCenter® services that employ state of the art phone, internet and electronic media to
manage customer communications. InTeleCenter programs include reimbursement hotlines, patient assistance programs and patient compliance programs. We also field and process telephone calls and
inquiries relating to adverse experiences with a drug while we perform the periapproval studies.

Customers and Marketing

We provide product development services on a global basis to, among others, the pharmaceutical and biotechnology industries. In 2006, we
served in excess of 300
biopharmaceutical companies, ranging from the world's largest pharmaceutical companies and biotechnology companies to small and start-up organizations.

While
no single customer accounted for more than ten percent of our aggregate net revenue in 2006, we had one customer accounting for more than five but less than ten percent of our net
revenues, and our top five customers accounted for less than 25 percent of our net revenues. In our early development segment, no single customer accounted for more than ten percent of net
revenues. Our early development segment had two customers accounting for more than five but less than ten percent of its aggregate net revenues. In our late-stage development segment, one
customer accounted for more than ten percent of net revenues and one customer accounted for more than five but less than ten percent of its aggregate net revenues.

For
net revenues from external customers, assets attributable to each of our business segments and other segment information for each of the last three fiscal years, please review
Note 12 to the audited consolidated financial statements included elsewhere in this Annual Report.

For
net revenues from external customers and long-lived assets attributable to operations in the United States, United Kingdom, Switzerland and other countries for each of
the last three fiscal years, please review Note 12 to the audited consolidated financial statements included elsewhere in this Annual Report.

Our
global sales activities are conducted by sales personnel based in our operations in the United States, Canada, Europe and Asia Pacific.

Contractual Arrangements

Many of our contracts with our clients are either fixed price or fee-for-service with a cap. To a lesser extent, some of our contracts
are fee-for-service without a cap. In cases where the contracts are fixed price, we generally bear the cost of overruns, but we benefit if the costs are lower than we
anticipated. In cases where our contracts are fee-for-service with a cap, the contracts contain an overall budget for the trial based on time and cost estimates. If our costs
are lower than anticipated, the customer generally keeps the savings, but if our costs are higher than estimated, we are responsible for the overrun unless the increased cost is a result of a scope
change or other factors outside of our control, such as an increase in the number of patients to be enrolled or the type or amount of data to be collected. Contracts may range in duration from a few
months to several years or longer depending on the nature of the work performed. In some cases, a portion of the contract fee is paid at the time the study or trial is started with the balance of the
contract fee payable in installments upon the achievement of milestones over the study or trial duration.

Most
of our contracts may be terminated by the customer either immediately or upon notice. These contracts typically require payment to Covance of expenses to wind down a study, payment
to Covance of fees earned to date, and, in some cases, a termination fee or payment to Covance of some portion of the fees or profit that could have been earned under the contract if it had not been
terminated early.

Backlog

Some of our studies and projects are performed over an extended period of time, which may exceed several years. We maintain an order
backlog to track anticipated
net revenues yet to be earned for work that has not yet been performed. However, we do not maintain an order backlog for other services that are performed within a short period of time or where it is
not otherwise practical or feasible to maintain an order backlog. Our aggregate backlog at December 31, 2006 and December 31, 2005 was $2.23 billion and $1.67 billion,
respectively.

Backlog
generally includes work to be performed under signed agreements (i.e., contracts and letters of intent). Once work under a signed agreement begins, net revenues are recognized
over the life of the project. However, in some cases we will begin work on a project once we conclude we have a legally binding agreement, but before executing a signed agreement, and backlog may
include the net revenues expected from that project.

We
cannot provide any assurance that we will be able to realize all or most of the net revenues included in backlog or estimate the portion expected to be filled in the current year.
Although backlog can provide meaningful information to our management with respect to a particular study, we believe that our aggregate backlog as of any date is not necessarily a meaningful indicator
of our future results for a variety of reasons. These reasons include the following: studies vary in duration; the scope of studies may change, which may either increase or decrease their value; and
studies may be terminated, reduced in scope or delayed at any time by the client or regulatory authorities.

Competition

The contract research organization industry has many participants ranging from hundreds of small, limited-service providers to a limited
number of full service
contract research organizations with global capabilities. We primarily compete against in-house departments of pharmaceutical companies, full-service and limited service
contract research organizations and, to a lesser extent, selected universities and teaching hospitals.

In
early development services, our significant competitors include Charles River Laboratories International Inc., MDS Inc., PPD, Inc., WIL Laboratories and MPI
Research, among others. In late-stage development services our significant competitors include PPD, Inc., Quintiles Transnational Corp., Parexel International Corporation, Kendle
International Inc., Icon PLC. eResearch Technology, Inc., PRA International, i3 Research, Pharmanet Development Group Inc. and Quest Diagnostics Incorporated, among others.
Covance represents an important market presence in each segment's principal services.

There
is competition for customers on the basis of many factors, including the following: reputation for on-time quality performance; expertise and experience in specific
areas; scope of service
offerings; strengths in various geographic markets; price; technological expertise and efficient drug development processes; ability to acquire, process, analyze and report data in a rapid and
accurate manner; historic experience and relationship ability to manage large-scale clinical trials both domestically and internationally; quality of facilities; expertise and experience in
reimbursement and healthcare consulting; and size. We believe that we compete favorably in these areas.

Government Regulation

Our laboratory services are subject to various regulatory requirements designed to ensure the quality and integrity of the testing
processes. Covance's standard
operating procedures are written in accordance with regulations and guidelines appropriate to the region and the nation where they will be used.

The
industry standards for conducting preclinical laboratory testing are embodied in the Good Laboratory Practice (GLP) and for central laboratory operations in the Clinical Laboratory
Improvement Amendments of 1988 (CLIA). The standards of GLP are required by the FDA, by the Department of Health in

6

---



the
United Kingdom, by the European Agency for the Evaluation of Medicinal Products (EMEA) in Europe and by similar regulatory authorities in other parts of the world. To help satisfy its compliance
obligations, Covance has established quality assurance controls at its laboratory facilities which monitor ongoing compliance with GLP and CLIA.

Our
clinical services are subject to industry standards for the conduct of clinical research and development studies that are embodied in the regulations for Good Clinical Practice
(GCP). The FDA, EMEA and other regulatory authorities require that test results submitted to such authorities be based on studies conducted in accordance with GCP. As with GLP and Good Manufacturing
Practice (GMP), noncompliance with GCP can result in the disqualification of data collected during the clinical trial.

We
strive to perform all clinical research in accordance with the International Conference on HarmonizationGood Clinical Practice Guidelines, and the requirements of the
applicable country. Although the U.S. is a signatory to these guidelines, the FDA has not adopted all of these guidelines as statutory regulations, but has currently adopted them only as guidelines.
From an international perspective, when applicable, we have implemented common standard operating procedures across regions to assure consistency whenever it is feasible and appropriate to do so.

Our
animal import and breeding facilities and toxicology facilities are also subject to a variety of federal and state laws and regulations, including The Animal Welfare Act and the
rules and regulations promulgated thereunder by the United States Department of Agriculture ("USDA") and corresponding rules and regulations in other jurisdictions. These facilities maintain detailed
standard operating procedures and the documentation necessary to comply with applicable regulations for the humane treatment of the animals in their custody. Besides being licensed by the USDA as a
dealer and/or research facility, as appropriate, these
businesses are also accredited by the Association for Assessment and Accreditation of Laboratory Animal Care International and have registered assurance with the United States National Institutes of
Health Office of Laboratory Animal Welfare.

The
use of controlled substances in testing for drugs with a potential for abuse is regulated in the United States by the U.S. Drug Enforcement Administration. All Covance United States
laboratories using controlled substances for testing purposes are licensed by the U.S. Drug Enforcement Administration.

Our
United States laboratories are subject to licensing and regulation under federal, state and local laws relating to hazard communication and employee
right-to-know regulations, the handling and disposal of medical specimens and hazardous waste and radioactive materials, as well as the safety and health of laboratory
employees. All of our laboratories are subject to applicable federal and state laws and regulations relating to the storage and disposal of all laboratory specimens including the regulations of the
Environmental Protection Agency, the Nuclear Regulatory Commission, the Department of Transportation, the National Fire Protection Agency and the Resource Conservation and Recovery Act. Although we
believe that Covance is currently in compliance in all material respects with such federal, state and local laws, failure to comply could subject Covance to denial of the right to conduct business,
fines, criminal penalties and other enforcement actions.

In
addition to its comprehensive regulation of safety in the workplace, the Occupational Safety and Health Administration and similar regulatory authorities in foreign countries have
established extensive requirements relating to workplace safety for health care employers, whose workers may be exposed to blood-borne pathogens such as HIV and the hepatitis B virus. Covance
employees receive initial and periodic training focusing on compliance with applicable hazardous materials regulations and health and safety guidelines.

In
the past few years, both the United States and foreign governments have become more concerned about the disclosure of confidential personal data. The European Union, or EU, now
prohibits certain disclosures of personal confidential information, including medical information, to any entity that does not comply with certain security safeguards. We will continue to monitor our
compliance with applicable regulations.

7

---





The regulations of the U.S. Department of Transportation, the U.S. Public Health Service and the U.S. Postal Service apply to the surface and air
transportation of laboratory specimens.
Covance's laboratories also must comply with the applicable International Air Transport Association regulations, which govern international shipments of laboratory specimens. Furthermore, when
materials are sent to a foreign country, the transportation of such materials becomes subject to the laws, rules and regulations of such foreign country.

Intellectual Property

We have developed certain computer software and technically derived procedures and products intended to maximize the quality and
effectiveness of our services.
Although our intellectual property rights are important to our results of operations, we believe that such factors as the technical expertise, knowledge, ability and experience of our professionals
are more important, and that, overall, these technological capabilities provide significant benefits to our clients.

Employees

At December 31, 2006, we had approximately 8,100 employees, approximately 34% of whom were employed outside of the United States and
approximately 7,300
of whom were full time employees. Our records indicate that 110 of our employees hold M.D. degrees, 209 hold Ph.D. degrees, and 747 hold masters or other postgraduate degrees. We believe that
Covance's relations with its employees are good.

Item 1A. Risk Factors

This section discusses various risk factors that are attendant with our business and the provision of our services. If the events outlined
below were to occur
individually or in the aggregate, our business, results of operations, financial condition, and cash flows could be materially adversely affected.

Changes in government regulation or in practices relating to the pharmaceutical industry could decrease  the need for the services we provide.

Governmental agencies throughout the world, but particularly in the United States, strictly regulate the drug development process. Our
business involves helping
pharmaceutical and biotechnology companies navigate the regulatory drug approval process. Changes in regulation, such as a relaxation in regulatory

9

requirements
or the introduction of simplified drug approval procedures, or an increase in regulatory requirements that we have difficulty satisfying or that make our services less competitive, could
eliminate or substantially reduce the demand for our services. Also, if government efforts to contain drug costs and pharmaceutical and biotechnology company profits from new drugs, our customers may
spend less, or reduce their growth in spending on research and development. If health insurers were to change their practices with respect to reimbursements for pharmaceutical products, our customers
may spend less, or reduce their growth in spending on research and development.

Failure to comply with existing regulations could result in a loss of revenue or earnings or in increased  costs.

Any failure on our part to comply with applicable regulations could result in the termination of on-going research or the disqualification
of data
for submission to regulatory authorities. For example, if we were to fail to properly monitor compliance by clinical trial investigators with study protocols, the data collected from that trial could
be disqualified. If this were to happen, we could be contractually required to repeat the trial at no further cost to our customer, but at substantial cost to us.

We may bear financial losses because most of our contracts are of a fixed price nature and may be delayed  or terminated or reduced in scope for reasons beyond our
control.

Many of our contracts provide for services on a fixed price or fee-for-service with a cap basis and they may be terminated or reduced in
scope either immediately or upon notice. Cancellations may occur for a variety of reasons, including:



The
loss, reduction in scope or delay of a large contract or the loss or delay of multiple contracts could materially adversely affect our business, although our contracts frequently
entitle us to receive the costs of winding down the terminated projects, as well as all fees earned by us up to the time of termination. Some contracts also entitle us to a termination fee.

We may bear financial risk if we under price our contracts or overrun cost estimates.

Since our contracts are often structured as fixed price or fee-for-service with a cap, we bear the financial risk if we initially under
price our contracts or otherwise overrun our cost estimates. Such under pricing or significant cost overruns could have a material adverse effect on our business, results of operations, financial
condition, and cash flows.

We may not be able to successfully develop and market or acquire new services.

We may seek to develop and market new services that complement or expand our existing business or expand our service offerings through
acquisition. If we are
unable to develop new services and/or create demand for those newly developed services, or to expand our service offerings through acquisition, our future business, results of operations, financial
condition, and cash flows could be adversely affected.

Our quarterly operating results may vary.

Our operating results may vary significantly from quarter to quarter and are influenced by factors over which we have little control such
as:



We
believe that operating results for any particular quarter are not necessarily a meaningful indication of future results. While fluctuations in our quarterly operating results could
negatively or positively affect the market price of our common stock, these fluctuations may not be related to our future overall operating performance.

We depend on the pharmaceutical and biotechnology industries.

Our revenues depend greatly on the expenditures made by the pharmaceutical and biotechnology industries in research and development.
Accordingly, economic
factors and industry trends that affect our clients in these industries also affect our business. If companies in these industries were to reduce the number of research and development projects they
outsource, our business could be materially adversely affected.

We operate in a highly competitive industry.

Competitors in the contract research organization industry range from small, limited-service providers to full service global contract
research organizations.
Our main competition consists of in-house departments of pharmaceutical companies, full-service and functional contract research organizations, and universities and teaching
hospitals, although to a lesser degree. We compete on a variety of factors, including:



For
instance, our clinical development services have from time to time experienced periods of increased price competition which had a material adverse effect on Covance's
late-stage development profitability and consolidated net revenues and net income.

There
is competition among the larger contract research organizations for both clients and potential acquisition candidates. Additionally, small, limited-service entities considering
entering the contract research organization industry will find few barriers to entry, thus further increasing possible competition. These competitive pressures may affect the attractiveness of our
services and could adversely affect our financial results.

We may expand our business through acquisitions.

We review many acquisition candidates and, in addition to acquisitions which we have already made, we are continually evaluating new
acquisition opportunities.
Factors which may affect our ability to grow successfully through acquisitions include:



We may be affected by potential health care reform.

In recent years the United States Congress and state legislatures have considered various types of health care reform in order to control
growing health care
costs. We are unable to predict what legislative proposals will be adopted in the future, if any. Similar reform movements have occurred in Europe and Asia.

Implementation
of health care reform legislation that contain costs could limit the profits that can be made from the development of new drugs. This could adversely affect research and
development expenditures by pharmaceutical and biotechnology companies which could in turn decrease the business opportunities available to us both in the United States and abroad. In addition, new
laws or regulations may create a risk of liability, increase our costs or limit our service offerings.

We rely on third parties for important services.

We depend on third parties to provide us with services critical to our business. For example, we have an agreement with IBM to manage
certain aspects of our
information technology infrastructure. The failure of any of these third parties to adequately provide the needed services could have a material adverse effect on our business.

Our revenues and earnings are exposed to exchange rate fluctuations.

We derive a large portion of our net revenues from international operations. For the year ended December 31, 2006, we derived
approximately 37% of our net
revenues from outside the United States. Our financial statements are denominated in U.S. dollars. In addition, in certain circumstances, we may incur costs in one currency related to our services or
products for which we are paid in a different currency. As a result, factors associated with international operations, including changes in foreign currency exchange rates, could significantly affect
our results of operations, financial condition and cash flows.

The loss of our key personnel could adversely affect our business.

Our success depends to a significant extent upon the efforts of our senior management team and other key personnel. The loss of the
services of such personnel
could adversely affect our business. Also, because of the nature of our business, our success is dependent upon our ability to attract and retain technologically qualified personnel. There is
substantial competition for qualified personnel, and an inability to recruit or retain qualified personnel may impact our ability to grow our business and compete effectively in our industry.

Contract research services create a risk of liability.

In contracting to work on drug development trials, we face a range of potential liabilities, for example:



We
also contract with physicians, also referred to as investigators, to conduct the clinical trials to test new drugs on human volunteers. These tests can create a risk of liability for
personal injury or death to volunteers, resulting from negative reactions to the drugs administered or from professional malpractice by third party investigators. We believe that our risks in this
area are generally reduced by the following:



Contractual
indemnifications generally do not protect us against liability arising from certain of our own actions, such as negligence or misconduct. We could be materially and
adversely affected if we were required to pay damages or bear the costs of defending any claim which is not covered by a contractual indemnification provision or in the event that a party who must
indemnify us does not fulfill its indemnification obligations or which is beyond the level of our insurance coverage. There can be no assurance that we will be able to maintain such insurance coverage
on terms acceptable to us.

Reliance on air transportation.

Our central laboratories and certain of our other businesses are heavily reliant on air travel for transport of clinical trial kits and
other material, products
and people, and a significant disruption to the air travel system, or our access to it, could have a material adverse effect on our business.

Certain service offerings and research products are dependent on limited sources of supply of services or  products which if interrupted could affect our business.

We depend on a limited number of suppliers for certain services and for certain animal populations. Disruptions to the continued supply of
these services or
products may arise from export import restrictions or embargoes, foreign political or economic instability, or otherwise. Disruption of supply could have a material adverse effect on our business.

Actions of animal rights extremists may affect our business.

Our early development services utilize animals in preclinical testing of the safety and efficacy of drugs and also breed and sell animals
for biomedical
research. Such activities are required for the development of new medicines and medical devices under regulatory regimes in the United States, Europe, Japan and other countries. Acts of vandalism and
other acts by animal rights extremists who object to the use of animals in drug development could have a material adverse effect on our business.

13

---



Our animal populations may suffer diseases that can damage our inventory, harm our reputation, result in  decreased sales of research products or result in other
liability to us.

It is important that our research products be free of diseases, including infectious diseases. The presence of diseases can distort or
compromise the quality of
research results, can cause loss of animals in our inventory, can result in harm to humans or outside animal populations if the disease is not contained to animals in inventory, or can result in other
losses. Such results could harm our reputation or have a material adverse effect on our financial condition, results of operations, and cash flows.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

Overview

Covance is a leading drug development services company providing a wide range of early-stage and late-stage product development services
on a
worldwide basis primarily to the pharmaceutical, biotechnology and medical device industries. Covance also provides services such as laboratory testing to the chemical, agrochemical and food
industries. The foregoing services comprise two reportable segments for financial reporting purposes: early development services, which includes preclinical and clinical pharmacology service
offerings; and late-stage development services, which includes central laboratory, clinical development, cardiac safety services, periapproval and market access services. Although each
segment has separate services within it, they can be combined in joint service offerings and we believe clients increasingly are interested in opportunities for such combined services. Covance
believes it is one of the largest drug development services companies, based on annual net revenues, and one of a few that is capable of providing comprehensive global product development services.
Covance offers its clients high quality services designed to provide data to clients as rapidly as possible and reduce product development time. We believe this enables Covance's customers to
introduce their products into the marketplace faster and as a result, maximize the period of market exclusivity and monetary return on their research and development investments. Additionally,
Covance's comprehensive services and broad experience provide its customers with a variable cost alternative to fixed cost internal development capabilities.

Critical Accounting Policies

Covance's consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles ("GAAP"), which
require management to
make estimates and assumptions about
future events that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ from these estimates. The following discussion highlights what we
believe to be the critical accounting policies and judgments made in the preparation of these consolidated financial statements.

Revenue Recognition.Covance recognizes revenue either as services are performed
or products are
delivered, depending upon the nature of the work contracted. Historically, a majority of Covance's net revenues have been earned under contracts which range in duration from a few months to two years,
but can extend in duration up to five years or longer. Service contracts generally take the form of fee-for-service or fixed-price arrangements. In the case of
fee-for-service contracts, revenue is recognized as services are performed, based upon, for example, hours worked or samples tested. For long-term fixed-price
service contracts, revenue is recognized as services are performed, with performance generally assessed using output measures, such as units-of-work performed to date as
compared to the total units-of-work contracted. Changes in the scope of work generally result in a renegotiation of contract pricing terms. Renegotiated amounts are not
included in net revenues until earned and realization is assured. Estimates of costs to complete are made to provide, where appropriate, for losses expected on contracts. Costs are not deferred in
anticipation of contracts being awarded, but instead are expensed as incurred. In some cases, a portion of the contract fee is paid at the time the trial is initiated. These advances are deferred and
recognized as revenue as services are performed or products are delivered, as discussed above. Additional payments may be made based upon the achievement of performance-based milestones over the
contract duration. Most contracts are terminable by the client either immediately or upon notice. These contracts typically require payment to Covance of expenses to wind down the study, fees earned
to date and, in some cases, a termination fee or a payment to Covance of some portion of the fees or profits that could have been earned by Covance under the contract if it had not been terminated
early. Termination fees are included in net revenues when realization is assured.

Bad Debts.Covance endeavors to assess and monitor the creditworthiness of its
customers to which it
grants credit terms in the ordinary course of business. Covance maintains a provision for doubtful accounts relating to amounts due that may not be collected. This bad debt provision is monitored on a
monthly basis and adjusted as circumstances warrant. Since the recorded bad debt provision is based upon management's

18

---



judgment,
actual bad debt write-offs may be greater or less than the amount recorded. Historically bad debt write-offs have not been material.

Taxes.Since Covance conducts operations on a global basis, its effective tax
rate has and will
continue to depend upon the geographic distribution of its pre-tax earnings among locations with varying tax rates. Covance's profits are further impacted by changes in the tax rates of
the various jurisdictions in which Covance operates. In addition, Covance maintains a tax reserve for uncertain tax positions, changes in which also impact Covance's effective tax rate in the period
in which such changes are made. The balance of this tax reserve, which is included in accrued expenses and other current liabilities on the consolidated balance sheets, at December 31, 2006 is
$8.4 million, and relates to exposures for tax matters such as transfer pricing, nexus, deemed dividends, VAT and the allocation of overhead costs across various Federal, state and foreign
income tax jurisdictions. By way of background, an accrual is established at the time an exposure is identified when it is both probable that a liability has been incurred and the amount of the
liability can be reasonably estimated. The amount of the accrual for each item for which an exposure exists
is adjusted when either (a) matters are settled at amounts which are different than the amount included in the reserve or (b) when facts indicate a significant change in either the
probability or estimated amount of the potential exposure. While Covance believes that it has identified all reasonably identifiable exposures and that the reserve it has established for identifiable
exposures is appropriate under the circumstances, it is possible that additional exposures exist and that exposures will be settled at amounts different than the amounts reserved. It is also possible
that changes in estimates in the future could cause Covance to either materially increase or reduce the carrying amount of its tax reserve. Significant activity relating to the reserve for uncertain
tax positions which occurred during 2006 included a $2.5 million reduction in the reserve during the third quarter of 2006 as a result of a favorable settlement with a foreign tax authority
relating to research and development tax credits totaling $1.8 million, as well as exposures as to which it is no longer probable that a liability exists relating primarily to transfer pricing
matters aggregating $0.7 million. Partially offsetting this reduction was an increase in the reserve balance during the fourth quarter of 2006 totaling $2.2 million relating to various
state and foreign tax exposures arising in the fourth quarter of 2006 as well as the accrual of additional interest on matters still outstanding. The effect of the fourth quarter increase in the
reserve balance on the effective tax rate was offset by a reduction in income taxes payable in the fourth quarter of approximately $2.2 million resulting from tax return to financial statement
accrual adjustments made to reflect actual amounts due upon filing of tax returns in the fourth quarter. See "Recently Issued Accounting Standards" on page 31.

Covance's
policy is to provide income taxes on earnings of foreign subsidiaries only to the extent those earnings are taxable or are expected to be remitted. Covance's historical policy
has been to leave its unremitted foreign earnings invested indefinitely outside the United States. Except for the amounts repatriated in the fourth quarter of 2005 under the American Jobs Creation Act
of 2004 (the "Act"), Covance intends to continue to leave its unremitted foreign earnings invested indefinitely outside the United States. As a result, taxes have not been provided on any accumulated
foreign unremitted earnings as of December 31, 2006.

Stock Based Compensation.The Company sponsors several stock-based compensation
plans pursuant to
which non-qualified stock options and restricted stock awards are granted to eligible employees. Through the year ended December 31, 2005, the Company followed the
disclosure-only provisions of Statement of Financial Accounting Standards No. 123,Accounting for Stock-Based Compensation,
("SFAS 123"), and, accordingly, accounted for awards under these plans pursuant to the recognition and measurement principles of Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to
Employees, ("APB 25") and related Interpretations, as permitted by SFAS 123. Under APB 25, compensation expense
was recognized in the financial statements relating to awards of stock. However, no compensation expense was recorded in the financial statements for stock option grants, as all options have been
granted with an exercise price equal to the market value of the underlying common stock on the date of grant. Additionally, no compensation expense was recorded in the financial statements for shares
purchased by employees under the Company's Employee Stock Purchase Plan (pursuant to which employees are able to purchase shares of the Company's common stock at a price equal to 85% of the lower of
the market value on the first or last day of each calendar quarter) as that plan was considered to be non-compensatory under APB 25.

Effective
January 1, 2006, the Company adopted the fair value recognition provisions of Statement of Financial Accounting Standards No. 123R, Share-Based Payments, ("SFAS 123R") using the modified
prospective transition method. SFAS 123R revises SFAS 123, supersedes APB 25 and amends Statement of Financial Accounting Standards No. 95,Statement of
Cash Flows. Under that transition method, compensation expense is now recognized in the financial statements on a go forward basis for (a) all share-based payments
granted prior to, but not vested as of January 1, 2006, based upon the grant-date fair value estimated in accordance with the original provisions of SFAS 123, and
(b) share-based payments granted on or subsequent to January 1, 2006, based upon the grant-date fair value estimated in accordance with the provisions of SFAS 123R.
The grant-date fair value of awards expected to vest is expensed on a straight-line basis over the vesting period of the related awards. Under the modified prospective
transition method, results for prior periods have not been restated.

Prior
to the adoption of SFAS 123R, the Company used stock options as the vehicle through which stock-based compensation awards were granted to eligible employees, other than
executive officers who historically were granted a combination of performance-based share awards and stock options. As a result of the adoption of SFAS 123R, the Company is now using a mix of
restricted share awards and stock options as the vehicles through which stock-based compensation awards are granted to eligible employees, other than executive officers who continue to receive a
combination of performance-based share awards and stock options.

The
grant-date fair value of stock awards is based upon the underlying price of the stock on the date of grant. The grant-date fair value of stock option awards
must be determined using an option pricing model. Option pricing models require the use of estimates and assumptions as to (a) the expected term of the option, (b) the expected
volatility of the price of the underlying stock, (c) the risk-free interest rate for the expected term of the option and (d) pre-vesting forfeiture rates. For
stock options granted prior to January 1, 2006, the Company used the Black-Scholes-Merton option pricing formula for determining the grant-date fair value of such awards. For stock
options granted on or subsequent to January 1, 2006, the Company is using the Lattice-Binomial option pricing formula for determining the grant-date fair value of stock option
awards. The Company changed to the Lattice-Binomial option pricing formula as it believes such formula may result in a better estimate of fair value than the Black-Scholes-Merton formula.

The
expected term of the option is based upon the contractual term and expected employee exercise and expected post-vesting employment termination behavior. The expected
volatility of the price of the underlying stock is based upon the historical volatility of the Company's stock computed over a period of time equal to the expected term of the option. The risk free
interest rate is based upon the implied yields currently available from the U.S. Treasury zero-coupon yield curve for issues with a remaining duration equal to the expected term of the
option. Pre-vesting forfeiture rates are estimated based upon past voluntary termination behavior and past option forfeitures.

The
following table sets forth the weighted-average assumptions used to calculate the fair value of options granted for the years ended December 31, 2006, 2005 and 2004:

2006

2005

2004Expected stock price volatility

3.9% - 4.5%


3.7%


3.4%Expected life of options (years)


4.3


5.0


6.0


Changes
in any of these assumptions could impact, potentially materially, the amount of expense recorded in future periods related to stock-based awards.

As
of December 31, 2006, the total unrecognized compensation cost related to non-vested stock options granted was $7.0 million and is expected to be recognized
over a weighted average period of
1.3 years. As of December 31, 2006, the total unrecognized compensation cost related to non-vested performance-based shares and restricted stock awards was
$20.0 million and is expected to be recognized over a weighted average period of 2.2 years.

Impairment of Assets.Covance reviews its long-lived assets other than goodwill
and
other indefinite lived intangible assets for impairment, when events or changes in circumstances occur that indicate that the carrying value of the asset may not be recoverable. The assessment of
possible impairment is based upon Covance's judgment of its ability to recover the asset from the expected future undiscounted cash flows of the related operations. Actual future cash flows may be
greater or less than estimated.

Covance
performs an annual test for impairment of goodwill and other indefinite lived intangible assets during the fourth quarter. This test is performed by comparing, at the reporting
unit level, the carrying value of the reporting unit to its fair value. Covance assesses fair value based upon its estimate of the present value of the future cash flows that it expects to be
generated by the reporting unit. The test performed for 2006 did not identify any instances of impairment. However, changes in expectations as to the present value of a reporting unit's future cash
flows might impact subsequent years' assessments of impairment.

Defined Benefit Pension Plans.Covance sponsors defined benefit pension plans for
the benefit of its
employees at three foreign subsidiaries as well as a non-qualified supplemental executive retirement plan and a post-employment retiree health and welfare plan for the benefit
of eligible employees at certain U.S. subsidiaries. The measurement of the related benefit obligation and net periodic benefit cost recorded each year is based upon actuarial computations which
require the use of judgment as to certain assumptions. The more significant of these assumptions are: (a) the appropriate discount rate to use in computing the present value of the benefit
obligation; (b) the expected return on plan assets (for funded plans); and (c) the expected future rate of salary increases (for pay-related plans). Actual results (such as
the return on plan assets, future rate of salary increases and plan participation rates) will likely differ from the assumptions used. Those differences, along with changes that may be made in the
assumptions used from period to period, will impact the amounts reported in the financial statements and footnote disclosures.

Set
forth below is a discussion of the impact that (a) differences between assumed results and actual results and (b) assumption changes have had on our results of
operations for the years ended December 31, 2006, 2005 and 2004 and on the financial position of the plans as of December 31, 2006 and 2005 for our UK defined benefit pension plans (the
largest of our defined benefit-type pension plans).

Foreign Currency Risks

Since Covance operates on a global basis, it is exposed to various foreign currency risks. Two specific risks arise from the nature of the
contracts Covance
executes with its customers since from time to time contracts are denominated in a currency different than the particular Covance subsidiary's local currency. These risks are generally applicable only
to a portion of the contracts executed by Covance's subsidiaries providing clinical services. The first risk occurs when revenue recognized for services rendered is denominated in a currency different
from the currency in which the subsidiary's expenses are incurred. As a result, the subsidiary's net revenues and resultant earnings can be affected by fluctuations in exchange rates. Historically,
fluctuations in exchange rates from those in effect at the time contracts were executed have not had a material effect upon Covance's consolidated financial results. See "Risk Factors".

The
second risk results from the passage of time between the invoicing of customers under these contracts and the ultimate collection of customer payments against such invoices. Because
the contract is denominated in a currency other than the subsidiary's local currency, Covance recognizes a receivable at the time of invoicing for the local currency equivalent of the foreign currency
invoice amount. Changes in exchange rates from the time the invoice is prepared and payment from the customer is received will result in Covance receiving either more or less in local currency than
the local currency equivalent of the invoice amount at the time the invoice was prepared and the receivable established. This difference is recognized by Covance as a foreign currency transaction gain
or loss, as applicable, and is reported in other expense (income) in Covance's Consolidated Statements of Income.

Finally,
Covance's consolidated financial statements are denominated in U.S. dollars. Accordingly, changes in exchange rates between the applicable foreign currency and the U.S. dollar
will affect the translation of each foreign subsidiary's financial results into U.S. dollars for purposes of reporting Covance's consolidated financial results. The process by which each foreign
subsidiary's financial results are translated into U.S. dollars is as follows: income statement accounts are translated at average exchange rates for the period; balance sheet asset and liability
accounts are translated at end of period exchange rates; and equity accounts are translated at historical exchange rates. Translation of the balance sheet in this manner affects the stockholders'
equity account, referred to as the cumulative translation adjustment account. This account exists only in the foreign subsidiary's U.S. dollar balance sheet and is necessary to keep the foreign
balance sheet stated in U.S. dollars in balance. At December 31, 2006, accumulated other comprehensive income on the consolidated balance sheet includes the cumulative translation account
balance of $35.2 million.

Operating Expenses and Reimbursable Out-of-Pockets

Covance segregates its recurring operating expenses among four categories: cost of revenue; reimbursed out-of-pocket expenses; selling,
general and administrative expenses; and depreciation and amortization. Cost of revenue includes direct labor and related benefits, other direct costs, shipping and handling fees, and an allocation of
facility charges and information technology costs, and excludes depreciation and amortization. Cost of revenue, as a percentage of net revenues, tends and is expected to fluctuate from one period to
another, as a result of changes in labor utilization and the mix of service offerings involving hundreds of studies conducted during any period of time. Selling, general and administrative expenses
consist primarily of administrative payroll and related benefit charges, advertising and promotional expenses, administrative travel and an allocation of facility charges and information technology
costs, and excludes depreciation and amortization.

In
connection with the management of multi-site clinical trials, Covance pays on behalf of its customers fees to investigators, volunteers and other
out-of-pocket costs (such as for travel, printing, meetings, couriers, etc.), for which it is reimbursed at cost, without mark-up or profit. Investigator fees are
not reflected in total revenues or expenses where Covance acts in the capacity of an agent on behalf of the pharmaceutical company sponsor, passing through these costs without risk or reward to
Covance. All other out-of-pocket costs are included in total revenues and expenses.

Results of Operations



Prior to 2006, the Company followed the disclosure-only provisions of SFAS 123, and, accordingly, accounted for awards under these
plans
pursuant to the recognition and measurement principles of APB 25 and related Interpretations, as permitted by SFAS 123. Under APB 25, compensation expense was recognized in the financial
statements relating to awards of stock. However, no compensation expense was recorded in the financial statements for stock option grants, as all options have been granted with an exercise price equal
to the market value of the underlying common stock on the date of grant. Additionally, no compensation expense was recorded in the financial statements for shares purchased by employees under the
Company's Employee Stock Purchase Plan (pursuant to which employees are able to purchase shares of the Company's common stock at a price equal to 85% of the lower of the market value on the first or
last day of each calendar quarter) as that plan was considered to be non-compensatory under APB 25. Covance reflected the expense associated with the fair value of stock-based awards in
its required pro forma footnote disclosure under SFAS 123 in its SEC filings.

Effective
January 1, 2006, the Company adopted the fair value recognition provisions of SFAS 123R using the modified prospective transition method. SFAS 123R
revises SFAS 123, supersedes APB 25 and amends Statement of Financial Accounting Standards No. 95,Statement of Cash Flows. Under that
transition method, compensation expense is now recognized in the financial statements on a prospective basis for (a) all share-based payments granted prior to, but not vested as of
January 1, 2006, based upon the grant-date fair value estimated in accordance with the original provisions of SFAS 123, and (b) share-based payments granted on or
subsequent to January 1, 2006, based upon the grant-date fair value estimated in accordance with the provisions of SFAS 123R. The grant-date fair value of awards
expected to vest is expensed on a straight-line basis over the vesting period of the related awards. Under the modified prospective transition method, results for prior periods have not
been restated.

Management
believes that it may be useful for investors, in evaluating current period financial performance, to compare to 2005 results that include stock-based compensation computed in
accordance with SFAS 123. Management does not assert that such pro forma numbers are superior to the 2005 "as reported" results; however, the pro forma numbers may help investors compare
results including stock option expense across both periods.

Although
the Company is now using the Lattice-Binomial option pricing formula for valuing stock options granted beginning in 2006 (whereas previously the Company had used the
Black-Scholes-Merton option pricing formula), management believes that the Lattice-Binomial and the Black-Scholes-Merton option pricing formulas, with the assumptions used by the Company, result in
fair values which are substantially similar in all material respects. As a result, the Company believes that the 2006 "as reported" amounts under SFAS 123R are comparable to the 2005 "pro
forma" amounts as previously disclosed under SFAS 123.

Year Ended December 31, 2006 Compared with Year Ended December 31, 2005.Net revenues
increased 12.3% to $1.34 billion for 2006 from $1.19 billion for 2005. Net revenues from Covance's early development segment grew 12.6% on strong performance in our global toxicology,
chemistry and clinical pharmacology services. Net revenues from Covance's late-stage development segment grew 12.2%, driven by strong performance in our central laboratory services.

Cost
of revenue increased 11.4% to $882.2 million or 65.8% of net revenues for the year ended December 31, 2006 as compared to $791.7 million or 66.4% of net
revenues for the corresponding 2005 period. Comparisons to the prior year are impacted by the inclusion of $7.0 million in stock-based compensation in cost of revenue in the 2006 period
pursuant to SFAS 123R. These expenses reduced 2006 gross margins by approximately 50 basis points to 34.2% of net revenues. Had stock-based compensation been included in cost of revenue for the
year ended December 31, 2005 under SFAS 123, cost of revenue would have been $7.8 million higher and gross margins (excluding depreciation and amortization) would have been
approximately 60 basis points lower or 33.0% of net revenue on a pro forma basis.

Overall,
selling, general and administrative expenses increased 16.3% to $207.4 million for 2006 from $178.4 million for 2005. As a percentage of net revenues, selling,
general and administrative expenses
increased 50 basis points to 15.5% for 2006 from 15.0% for 2005. Comparisons to the prior year are impacted by the inclusion of $8.5 million in stock-based compensation in selling, general and
administrative expenses in the 2006 period pursuant to SFAS 123R. These expenses increased selling, general and administrative expenses as a percentage of revenue by approximately 70 basis
points. Had incremental stock-based compensation been included in selling, general and administrative expenses for the year ended December 31, 2005 under SFAS 123, selling, general and
administrative expenses would have been $9.6 million higher and selling, general and administrative expenses as a percentage of revenue would have been approximately 80 basis points higher or
15.8% of net revenue on a pro forma basis.

Depreciation
and amortization increased 20.0% to $57.4 million or 4.3% of net revenues for 2006 from $47.8 million or 4.0% of net revenues for 2005 primarily as a result
of higher levels of capital spending over the last fifteen months.

Income
from operations increased 10.4% to $193.2 million or 14.4% of net revenues for 2006 from $175.1 million or 14.7% of net revenues for the corresponding 2005 period.
Comparisons to the prior year are impacted by the inclusion of $15.5 million in stock-based compensation in operating expenses in the 2006 period pursuant to SFAS 123R. These expenses
reduced operating margin by approximately 120 basis points. Had incremental stock-based compensation been included in operating expenses for the year ended December 31, 2005 under
SFAS 123, operating expenses would have been $17.4 million higher and operating margins would have been approximately 150 basis points lower or 13.2% of net revenue on a pro forma basis.

Income
from operations from Covance's early development segment increased $13.5 million or 9.6% to $153.6 million or 24.3% of net revenues for the year ended
December 31, 2006 from $140.1 million or 24.9% of net revenues for the corresponding 2005 period. The $13.5 million increase over the prior year was driven primarily by strength
in our global toxicology and chemistry services, partially offset by softness in our research products and dilution resulting from the 2006 acquisition of Radiant Research Inc. ("Radiant"). The
dilutive impact on 2006 operating margins from Radiant was 100 basis points. Income from operations from Covance's late-stage development segment increased $19.0 million or 18.1% to
$123.7 million for the year ended December 31, 2006 from $104.7 million for the corresponding 2005 period. Income from operations as a percentage of net revenues increased to
17.5% for the year ended December 31, 2006 from 16.6% for the

24

corresponding
2005 period,driven by strength in our central laboratory services. Corporate expense increased $14.3 million to
$84.0 million or 6.3% of net revenues for 2006 from $69.7 million or 5.8% of net revenues for 2005. Comparisons to the prior year are impacted by the inclusion of $15.5 million or
1.2% of net revenues in stock-based compensation in corporate expenses in the 2006 period pursuant to SFAS 123R. Had incremental stock-based compensation been included in corporate expenses for
the year ended December 31, 2005 under SFAS 123, corporate expenses would have been $17.4 million higher, totaling $87.1 million or 7.3% of net revenue on a pro forma
basis. The reduction from $87.1 million in 2005 to $84.0 million in 2006 is primarily due to lower stock-based and incentive compensation and professional fees in the year ended
December 31, 2006.

Other
income, net increased $4.8 million to $7.4 million for 2006 from $2.6 million for 2005 primarily as a result of a $3.9 million increase in net interest
income resulting from higher invested cash balances and higher average interest rates earned on those balances in 2006.

Covance's
effective tax rate for the year ended December 31, 2006 was 28.5% compared to 33.1% for the corresponding 2005 period. The effective tax rate for 2006 includes the
impact of a $2.5 million reduction in income tax reserves resulting from favorable income tax developments arising in the third quarter. The 2006 effective rate also reflects increases to the
tax reserves recorded during the fourth quarter of 2006 for new exposures which arose and interest on matters still outstanding totaling $2.2 million, which was offset by a reduction in income
taxes payable recorded during the fourth quarter of 2006 resulting from tax return to financial statement accrual adjustments made to reflect actual amounts due upon the filing of tax returns in 2006.
The effective tax rate for 2005 includes the impact of a $4.4 million income tax charge associated with the repatriation of $103 million of accumulated foreign earnings during the fourth
quarter under the American Jobs Creation Act. The impact of the 2006 tax gain and 2005 tax charge on Covance's effective tax rate was a 120 basis point reduction in 2006 and a 250 basis point increase
in 2005. Other factors impacting the effective tax rate from 2005 to 2006 include a shift in the mix of our pre-tax earnings across various tax jurisdictions, increased research and
development tax credits in the United Kingdom and other initiatives.

Covance
has a minority equity position (approximately 21% at December 31, 2006) in Bio-Imaging Technologies, Inc. ("BITI"). BITI uses proprietary medical
imaging technologies to process and analyze medical images, and also provides other services, including the data-basing and regulatory submission of medical images, quantitative data and
text. During the years ended December 31, 2006 and 2005, Covance recognized income of $0.02 million and a loss of $0.5 million, respectively, representing its share of BITI's
results.

Covance
has a 47% minority equity position in Noveprim Limited, a supplier of research products. During the years ended December 31, 2006 and 2005, Covance recognized
$1.6 million and $1.3 million, respectively, representing its share of Noveprim's earnings, less an elimination of profit on inventory purchased from Noveprim Limited and still on hand
at Covance at December 31, 2006 and 2005.

Net
income of $145.0 million for the year ended December 31, 2006 increased $25.4 million or 21.2% as compared to $119.6 million for the corresponding 2005
period. Comparisons to the prior year are impacted by the inclusion of $10.6 million, net of tax, in stock-based compensation in the 2006 period pursuant to SFAS 123R, the tax gain of
$2.5 million in 2006 and the tax charge of $4.4 million in 2005. Had incremental stock-based compensation been included in net income for the year ended December 31, 2005 under
SFAS 123, and had net income in both periods excluded the tax gain/(charge), on a proforma basis, net income for the year ended December 31, 2006 would have increased
$30.4 million, or 27.1%, as compared to net income for the year ended December 31, 2005.

Year Ended December 31, 2005 Compared with Year Ended December 31, 2004.Net revenues
increased 16.9% to $1.19 billion for 2005 from $1.02 billion for 2004. Net revenues from Covance's early development segment grew 17.4% on the strong broad-based performance across the
segment's service offerings. Net revenues from Covance's late-stage development segment increased 16.4% on the strong broad-based performance across this segment's service offerings.

Cost
of revenue increased 16.8% to $791.7 million or 66.4% of net revenues for the year ended December 31, 2005 as compared to $677.9 million or 66.4% of net
revenues for the corresponding 2004 period. Gross margins were 33.6% for each of the years ended December 31, 2005 and December 31, 2004.

Overall,
selling, general and administrative expenses increased 14.6% to $178.4 million for 2005 from $155.7 million for 2004. As a percentage of net revenues, selling,
general and administrative expenses declined 30 basis points to 15.0% in 2005 from 15.3% in 2004.

Depreciation
and amortization increased 3.2% to $47.8 million or 4.0% of net revenues for 2005 from $46.4 million or 4.5% of net revenues for 2004.

Income
from operations increased 24.7% to $175.1 million or 14.7% of net revenues for 2005 from $140.5 million or 13.8% of net revenues for the corresponding 2004 period.
Income from operations from Covance's early development segment increased $28.5 million or 25.6% to $140.1 million or 24.9% of net revenues for the year ended December 31, 2005
from $111.6 million or 23.3% of net revenues for the corresponding 2004 period on the strong broad-based performance across the segment's service offerings. Income from operations from
Covance's late-stage development segment increased $19.8 million or 23.3% to $104.7 million or 16.6% of net revenues for 2005 from $84.9 million or 15.7% of net
revenues for the corresponding 2004 period, primarily driven by strong performances in our central laboratory and cardiac safety services. Corporate expense increased $13.7 million to
$69.7 million or 5.8% of net revenues for 2005 from $56.0 million or 5.5% of net revenues for 2004. The increase is primarily attributable to increased centralized information technology
and human resources costs, incentive compensation accruals and professional fees.

Other
income, net of $2.6 million for 2005 increased $0.5 million compared to $2.1 million for 2004. This increase is the result of a $0.8 million increase
in interest income due primarily to higher average interest rates earned on invested cash balances combined with a $0.5 million decrease in interest expense due to lower amortized loan fees
associated with our revolving credit facility which were partially offset by a $0.8 million increase in foreign exchange transaction losses.

Results
for 2005 include the impact of a one-time $4.4 million income tax charge associated with the repatriation of $103 million of accumulated foreign
earnings under the American Jobs Creation Act of 2004. See Notes 2 and 7 to the audited consolidated financial statements included elsewhere in this Annual Report. Below is a reconciliation between
the amounts "as reported" on a GAAP basis and amounts "as adjusted" on a non-GAAP basis to exclude the impact of the $4.4 million repatriation related tax charge. This information
is provided because management believes that results including this $4.4 million one-time tax charge are not indicative of Covance's operational results and, as this
non-GAAP measure is used by management as a basis for evaluating the Company's performance, investors' understanding of Covance's performance is enhanced by such disclosure.

Covance's
effective tax rate for the year ended December 31, 2005 was 33.1% as compared to 31.9% for the corresponding 2004 period. The 120 basis point increase in Covance's
effective tax rate is due to the one-time $4.4 million income tax charge associated with the repatriation of $103 million of accumulated foreign earnings under the American
Jobs Creation Act. Taxes on income of $58.8 million would have been $54.4 million, or $4.4 million lower, excluding this one-time tax charge, and the effective tax
rate of 33.1% would have been 30.6% or 250 basis points lower than the prior year. This decrease is attributable to a number of factors, including the mix of our pre-tax earnings across
various tax jurisdictions, research and development tax credits in the United Kingdom, and other planning initiatives.

Covance
has a minority equity position (approximately 21% at December 31, 2005) in Bio-Imaging Technologies, Inc. ("BITI"). BITI uses proprietary medical
imaging technologies to process and analyze medical images, and also provides other services, including the data-basing and regulatory submission of medical images, quantitative data and
text. During the years ended December 31, 2005 and 2004, Covance recognized a loss of $0.5 million and income of $0.5 million, respectively, representing its pro rata share of
BITI's earnings (losses).

Covance
has a 47% minority equity position in Noveprim Limited, an existing supplier of research products. Covance began recognizing earnings from this investment in the second quarter
of 2004. During the years ended December 31, 2005 and 2004, Covance recognized $1.3 million and $0.4 million, respectively, representing its share of Noveprim's earnings, less the
elimination of profit on inventory purchased from Noveprim Limited and still on hand at Covance at December 31, 2005 and 2004.

Net
income of $119.6 million for the year ended December 31, 2005 increased $21.7 million or 22.1% as compared to $97.9 million for the corresponding 2004
period. Excluding the one-time $4.4 million income tax charge associated with the repatriation of foreign earnings under the American Jobs Creation Act, net income would have been
$124.0 million for the year ended December 31, 2005, an increase of $26.1 million or 26.6% over the corresponding 2004 period.

Quarterly Results

Covance's quarterly operating results are subject to variation, and are expected to continue to be subject to variation, as a result of
factors such as
(1) delays in initiating or completing significant drug development trials, (2) termination or reduction in size of drug development trials, (3) acquisitions and divestitures,
(4) changes in the mix of our services, and (5) exchange rate fluctuations. Delays and terminations of trials are often the result of actions taken by Covance's customers or regulatory
authorities and are not typically controllable by Covance. Since a large amount of Covance's operating costs are relatively fixed while revenue is subject to fluctuation, moderate variations in the
commencement, progress or completion of drug development trials may cause significant variations in quarterly results.

The
following table presents unaudited quarterly operating results of Covance for each of the eight most recent fiscal quarters during the period ended December 31, 2006. In the
opinion of Covance, the information in the table below has been prepared on the same basis as the audited consolidated financial statements included elsewhere in this Annual Report and reflects all
adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of results of operations for those periods. This quarterly financial data should be read in conjunction
with the audited consolidated financial statements included elsewhere in this Annual Report. Operating results for any quarter are not necessarily indicative of the results that may be reported in any
future period.

Liquidity and Capital Resources

Covance has a centralized cash management function. In the United States, cash received from operations is swept daily to a centrally
managed concentration
account, while cash disbursements for operations are funded as needed from the concentration account. Excess cash balances are invested in high quality money market funds of short duration. Outside of
the United States, cash balances are generally pooled by currency in order to facilitate cash management and improve investment returns. As in the United States, cash balances are generally maintained
in the functional currency of the operating unit.

Covance's
expected primary cash needs on both a short and long-term basis are for capital expenditures, expansion of services, possible future acquisitions, geographic
expansion, working capital and other general corporate purposes, including possible share repurchases. Covance's $75.0 million revolving credit facility (the "Credit Facility") expires in
June 2009 and may be expanded to $125.0 million at Covance's election. Covance believes cash from operations will provide sufficient liquidity for the foreseeable future. At
December 31, 2006, there were no outstanding borrowings and $0.8 million of outstanding letters of credit
under the Credit Facility. Interest on all outstanding borrowings under the Credit Facility is based upon the London Interbank Offered Rate ("LIBOR") plus a 75 basis point margin. Costs associated
with the Credit Facility consisted primarily of bank fees totaling $0.4 million which are being amortized over the five year facility term. The Credit Facility contains various financial and
other covenants. At December 31, 2006, Covance was in compliance with the terms of the Credit Facility. The Credit Facility is collateralized by guarantees of certain of Covance's domestic
subsidiaries and a pledge of 65 percent of the capital stock of certain of Covance's foreign subsidiaries. A commitment fee of 15 basis points on the undrawn balance of the Credit Facility is
payable in arrears on the first day of each July, October, January and April, and totaled approximately $0.1 million during each of the years ended December 31, 2006 and 2005.

As
discussed in Note 11 to the audited consolidated financial statements included elsewhere in this Annual Report, and as set forth in the table below, Covance is obligated under
non-cancelable operating leases, primarily for its offices and laboratory facilities. Covance is also obligated under outsourcing agreements related to certain aspects of its information
technology and human resources support functions and purchase commitments related to the completion of ongoing facility expansions, both of which are reflected under the caption purchase obligations
in the table below. Actual amounts paid under these outsourcing agreements could be higher or lower than the amounts shown below as a result of changes in volume and other variables. In addition,
early termination of these outsourcing agreements by Covance could result in the payment of termination fees which are not reflected in the table below.

During the year ended December 31, 2006, Covance's operations provided net cash of $254.2 million, an increase of
$72.1 million from the corresponding 2005 period. The change in net operating assets provided $22.4 million in cash during 2006, primarily due to an increase in accrued liabilities,
unearned revenue and accounts payable, partially offset by an increase in prepaids and other current assets, while this net change used $7.3 million in cash in 2005, primarily due to an
increase in accounts receivable and unbilled services, partially offset by increases in income taxes payable, accrued liabilities and unearned revenue. Covance's ratio of current assets to current
liabilities was 2.21 at December 31, 2006 and 2.16 at December 31, 2005.

Investing
activities for the year ended December 31, 2006 used $211.7 million, compared to using $160.1 million for the corresponding 2005 period. Capital spending
for 2006 totaled $136.8 million, and was primarily for the expansion of our preclinical facilities in North America and Europe, outfitting of new facilities, upgrade of existing equipment,
purchase of new equipment, hardware and software for newly hired employees. Capital spending for the corresponding 2005 period totaled $153.1 million, and was primarily for the expansion of our
preclinical facilities in North America and the United Kingdom, outfitting of new facilities, upgrade of existing equipment, purchase of new equipment and software for newly hired employees. Investing
activities for 2006 included the acquisitions of Radiant and Signet Laboratories, Inc. ("Signet") for approximately $75.7 million. Investing activities for 2005 included the acquisitions
of an antibody products provider and an 80 bed Phase I clinic for cash payments totaling $7.1 million.

In
2006, Covance acquired the stock of Radiant in a merger transaction for cash payments aggregating approximately $66.6 million (including direct acquisition costs of
$0.5 million). Radiant operates eight early development clinical sites performing Phase I/IIa clinical trial services. Results of operations for Radiant, which are now part of Covance's Early
Development segment service offering, and the fair value of Radiant's assets and liabilities acquired, are included in Covance's consolidated financial statements beginning June 1, 2006. The
fair value of Radiant's net assets was $9.2 million. Intangible assets acquired were valued at $6.8 million. The remaining purchase price of $50.6 million represents goodwill.

In
2006, Covance also acquired certain assets and liabilities of Signet for cash payments totaling $9.1 million (including direct acquisition costs of $0.2 million).
Signet specializes in the development of monoclonal antibodies and diagnostic assays for cancer, infectious diseases and neurodegenerative diseases. Results of operations for Signet, which are now
part of Covance's Early Development segment service offering, and the fair value of Signet's assets and liabilities acquired, are included in Covance's consolidated financial statements beginning
June 1, 2006. The fair value of Signet's net assets was $0.4 million.Intangible assets acquired were valued at $0.9 million. The
remaining purchase price of $7.9 million represents goodwill.

Financing
activities for the year ended December 31, 2006 provided $11.9 million and were primarily comprised of proceeds from the exercise of stock options of
$28.4 million, excess tax benefits realized on the exercise of stock options of $7.3 million (which are now required to be included in financing cash flows pursuant to SFAS 123R)
and employee contributions to Covance's employee stock purchase plan of $4.2 million, partially offset by the purchase into treasury of 414,100 shares of common stock in connection with a
3.0 million share buyback program authorized by Covance's Board of Directors in June 2004, and the purchase into treasury of 68,829 shares in connection with employee benefit plans, for
an aggregate cost of $28.0 million. Financing activities for the year ended December 31, 2005 used $25.8 million and consisted primarily of the purchase into treasury of 1,195,500
shares of common stock in connection with two separate 3.0 million share buyback programs authorized by Covance's Board of Directors in February 2003 and June 2004, and the
purchase into treasury of 106,500 shares in connection with employee benefit plans, for an aggregate cost of $58.2 million. The use of cash for these share repurchases was partially offset by
cash received from stock option exercises and employee contributions to Covance's employee stock purchase plan totaling $32.4 million. At December 31, 2006, there are approximately
0.3 million shares remaining for repurchase under the Board authorized buyback program. In February 2007, Covance's Board of Directors authorized the repurchase of an additional
3.0 million shares under Covance's stock repurchase program, bringing the total number of shares available for repurchase under the Board authorized share buyback program to 3.3 million.

In
2006, Covance and IBM amended the terms of the contract under which IBM had been providing certain information technology services to Covance. Pursuant to the terms of the amended
contract, Covance has in-sourced certain elements of its information technology infrastructure support which were being provided by IBM. IBM is continuing to provide information technology
support services in areas including help desk and desktop computer support on a worldwide basis. This amended contract has not had, nor is it expected to have, a material impact upon Covance's
liquidity.

The
effect of exchange rate changes on cash for the year ended December 31, 2006 was an increase of $4.7 million versus a $13.2 million reduction for the prior
year. Covance's cash balances increased by $59.1 million to $219.8 million at December 31, 2006 from $160.7 million at December 31, 2005.

Off-Balance Sheet Arrangements

At December 31, 2006 and 2005, Covance was not a party to any off-balance sheet arrangements as defined by Regulation S-K
Item 303(a)(4)(i), promulgated under the Exchange Act.

Inflation

While most of Covance's net revenues are earned under contracts, the long-term contracts (those in excess of one year) generally include
an inflation
or cost of living adjustment for the portion of the services to be performed beyond one year from the contract date. As a result, Covance believes that the effects of inflation generally do not have a
material effect on its operations or financial condition.

Recently Issued Accounting Standards

In September 2006, the Financial Accounting Standards Board (the "FASB") issued Statement of Financial Accounting Standards
No. 158, Employers' Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106 and 132(R),("SFAS 158"). As of December 31, 2006, Covance has adopted the recognition and disclosure provisions of SFAS 158, which require an employer to recognize the over funded or under
funded status of its defined benefit postretirement plansmeasured as the difference between the fair value of plan assets and the projected benefit obligationas an asset or
liability, respectively, in its balance sheet and to recognize changes in the funded status of the plan in the year in which such changes occur through other comprehensive income. The adoption of
SFAS 158 did not have an impact on our consolidated results of operations. The impact of adopting SFAS 158 on our consolidated balance sheet at December 31, 2006 was an increase
in non-current liabilities of $21.3 million, reflecting the under funded status of the plans, a reduction in other assets of $12.8 million, from the elimination of the
prepaid pension asset which existed under SFAS 87, the recording of a long-term deferred tax asset of $10.7 million and a reduction in the other comprehensive income equity account
of $23.4 million. SFAS 158 also requires, effective for fiscal years ending after December 15, 2008, that the measurement of the over funded or under funded status of a plan be
made as of the employer's fiscal year end and not as of an earlier measurement date. Covance will be required to conform the measurement dates of its plans to December 31st for
its fiscal year ending December 31, 2008. Covance does not expect this change in measurement dates to have a material impact on its consolidated results of operations or financial position.

In
September 2006, the FASB issued SFAS No. 157,Fair Value Measurements,("SFAS 157"). SFAS 157, which
applies whenever other standards require (or permit) fair value measurement, defines fair value and provides guidance for using fair value to measure assets and liabilities. SFAS 157 also
requires expanded disclosures about the extent to which companies measure assets and liabilities at fair value, the information used in those measurements and the effect of fair value measurements on
earnings. Covance will be required to adopt SFAS 157, which is effective for fiscal years beginning after November 15, 2007, no later than the quarter beginning January 1, 2008.
Covance is currently in the process of evaluating SFAS 157, and has not yet determined the impact, if any, SFAS 157 will have on its consolidated results of operations or financial
position.

In
June 2006, the FASB issued Interpretation No. 48,Accounting for Uncertainty in Income Taxesan Interpretation of FASB Statement
No. 109("FIN 48"). This authoritative interpretation clarifies and standardizes the manner by which companies will be required to account for uncertain tax positions.
Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006. Covance is required to adopt FIN 48 for its first quarter ending March 31, 2007 and is currently
finalizing its estimate of the impact of adopting FIN 48. Covance currently estimates that the reserve for uncertain tax positions, which totals $8.4 million at December 31, 2006 under
SFAS 109 and SFAS 5, will be between $9.0 million and $12.0 million as calculated under the measurement provisions of FIN 48. The additional reserve for uncertain tax positions,
currently estimated in the range of $0.6 million to $3.6 million, will be recorded to retained earnings in the first quarter of 2007 as a cumulative effect change of adopting a new
accounting pronouncement.

In
June 2006, the Emerging Issues Taskforce reached a consensus on EITF Issue No. 06-3,How Taxes Collected from Customers and Remitted
to Government Authorities Should be Presented in the Income Statement (That Is, Gross versus Net Presentation, ("EITF 06-3") which addresses the income statement
disclosure on taxes assessed by a governmental authority that are directly imposed on a revenue-producing transaction between a seller and a customer. Taxes within the scope of EITF 06-3
include sales taxes, use taxes, value-added taxes and some types of excise taxes. For any such taxes that are reported on a gross basis, EITF 06-3, which is effective for interim periods
beginning after December 15, 2006, requires disclosure of the amounts of those taxes in interim and annual financial statements for each period in which an income statement is presented.
Covance currently accounts for such taxes on a net basis, therefore, EITF 06-3 is not expected to have any impact on the Company's consolidated results of operations or financial position.

Management's Report on Consolidated Financial Statements and Internal Control

The
management of Covance Inc. ("Covance") has prepared, and is responsible for, Covance's consolidated financial statements and related footnotes. These consolidated financial
statements have been prepared in conformity with U.S. generally accepted accounting principles.

Covance's
management is responsible for establishing and maintaining effective internal control over financial reporting and for assessing the effectiveness of internal control over
financial reporting. The purpose of this system of internal accounting controls over financial reporting is to provide reasonable assurance that assets are safeguarded, that transactions are executed
in accordance with management's authorization and are properly recorded, and that accounting records may be relied upon for the preparation of accurate and complete consolidated financial statements.
The design, monitoring and revision of internal accounting control systems involve, among other things, management's judgment with respect to the relative cost and expected benefits of specific
control measures. Covance also maintains an internal audit function that evaluates and reports on the adequacy and effectiveness of internal controls, policies and procedures.

Covance's
management concluded that its internal control over financial reporting as of December 31, 2006 was effective and adequate to accomplish the objectives described above.
Management's assessment was based upon the criteria in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Covance's
consolidated financial statements and the effectiveness of control over financial reporting have been audited by an independent registered public accounting firm, Ernst & Young LLP, as stated
in their reports which are included elsewhere herein.

Report of Independent Registered Public Accounting Firm

The
Board of Directors and Stockholders
Covance Inc.

We
have audited management's assessment, included in Management's Report on Consolidated Financial Statements and Internal Control, that Covance Inc. maintained effective
internal control over financial reporting as of December 31, 2006, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (the COSO criteria). Covance Inc.'s management is responsible for maintaining effective internal control over financial reporting and for its assessment
of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management's assessment and an opinion on the effectiveness of the company's internal
control over financial reporting based on our audit.

We
conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control
over financial reporting, evaluating management's assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered
necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A
company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of
financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures
that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and
expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because
of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future
periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In
our opinion, management's assessment that Covance Inc. maintained effective internal control over financial reporting as of December 31, 2006, is fairly stated, in all
material respects, based on the COSO criteria. Also, in our opinion, Covance Inc. maintained, in all material respects, effective internal control over financial reporting as of
December 31, 2006, based on the COSO criteria.

We
also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Covance Inc. and
subsidiaries as of December 31, 2006 and 2005, and the related consolidated statements of income, shareholders' equity, and cash flows for each of the three years in the period ended
December 31, 2006 and our report dated February 22, 2007 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

The
Board of Directors and Stockholders
Covance Inc.

We
have audited the accompanying consolidated balance sheets of Covance Inc. and subsidiaries as of December 31, 2006 and 2005, and the related consolidated statements of
income, shareholders' equity, and cash flows for each of the three years in the period ended December 31, 2006. These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based on our audits.

We
conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our opinion.

In
our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Covance Inc. and subsidiaries at
December 31, 2006 and 2005, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2006, in conformity with
U.S. generally accepted accounting principles.

As
discussed in Note 2 to the consolidated financial statements, in 2006 the Company adopted SFAS No. 123(R), "Share-Based Payments" applying the modified prospective
method at the beginning of fiscal year 2006. Also, as discussed in Note 2 to the consolidated financial statements, the Company adopted SFAS No. 158, "Employers' Accounting for Defined
Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106 and 132(R)" at the end of fiscal year 2006.

We
also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of Covance Inc.'s internal control over
financial reporting as of December 31, 2006, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the
Treadway Commission, and our report dated February 22, 2007 expressed an unqualified opinion thereon.

COVANCE INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 2006, 2005 AND 2004
(Dollars in thousands, unless otherwise indicated)

1.    Organization

Covance Inc. and its subsidiaries ("Covance" or the "Company") is a leading drug development services company providing a wide range
of early-stage and
late-stage product development services on a worldwide basis primarily to the pharmaceutical, biotechnology and medical device industries. Covance also provides services such as laboratory
testing to the chemical, agrochemical and food industries. Covance's operations constitute two segments for financial reporting purposes. The first segment, early development services, includes
preclinical and clinical pharmacology service offerings. The second segment, late-stage development services, includes central laboratory, clinical development, cardiac safety services,
periapproval and market access services. Operations are principally focused in the United States and Europe.

2.    Summary of Significant Accounting Policies



The consolidated financial statements include the accounts of all entities controlled by Covance. All significant intercompany accounts
and transactions are
eliminated. The equity method of accounting is used for investments in affiliates in which Covance owns between 20 and 50 percent and does not have the ability to exercise control. See
Note 5.



These consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles ("GAAP"),
which requires management
to make estimates and assumptions about future events that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ from these estimates.



For subsidiaries outside of the United States that operate in a local currency environment, income and expense items are translated to
United States dollars at
the monthly average rates of exchange prevailing during the year, assets and liabilities are translated at year-end exchange rates and equity accounts are translated at historical exchange
rates. Translation adjustments are accumulated in a separate component of stockholders' equity in the Consolidated Balance Sheets and are included in the determination of comprehensive income in the
Consolidated Statements of Stockholders' Equity. Transaction gains and losses are included in the determination of net income in the Consolidated Statements of Income.



Cash and cash equivalents include all highly liquid investments with an original maturity of three months or less at date of purchase and
consist principally of
amounts invested in money market funds.



The fair value of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate their carrying amounts
as reported at
December 31, 2006 and 2005.

DECEMBER 31, 2006, 2005 AND 2004
(Dollars in thousands, unless otherwise indicated)

2.    Summary of Significant Accounting Policies (Continued)

Accounts
receivable and unbilled services represent amounts due from Covance customers who are concentrated primarily in the pharmaceutical and biotechnology industries. Covance
endeavors to monitor the creditworthiness of its customers to which it grants credit terms in the ordinary course of business. Although Covance customers are concentrated primarily within these two
industries, management considers the likelihood of material credit risk as remote. In addition, in some cases Covance requires advance payment for a portion of the contract price from its customers
upon the signing of a contract for services. These amounts are deferred and recognized as revenue as services are performed. Historically, bad debts have been immaterial.



Inventories, which consist principally of finished goods and supplies, are valued at the lower of cost (first-in, first-out method) or
market.



In connection with the management of multi-site clinical trials, Covance pays on behalf of its customers fees to investigators, volunteers
and other
out-of-pocket costs (such
as travel, printing, meetings, couriers, etc.), for which we are reimbursed at cost, without mark-up or profit. Amounts receivable from customers in connection with billed and unbilled
investigator fees, volunteer payments and other out-of-pocket pass-through costs are included in prepaid expenses and other current assets in the accompanying
Consolidated Balance Sheets and totaled $37.7 million and $31.6 million at December 31, 2006 and 2005, respectively. See Note 2 "Reimbursable
Out-of-Pocket Expenses".



Property and equipment are recorded at cost. Depreciation and amortization are provided on the straight-line method at rates adequate to
allocate the
cost of the applicable assets over their estimated useful lives, which generally range from ten to forty years for buildings and improvements, three to ten years for equipment, furniture and fixtures
and three to five years for computer hardware and software. Leasehold improvements are capitalized and amortized on a straight-line basis over the shorter of the estimated useful life of
the improvement or the associated remaining lease term. The cost of computer software developed or obtained for internal use is accounted for in accordance with the Accounting Standards Executive
Committee's Statement of Position 98-1,Accounting for the Costs of Computer Software Developed or Obtained for Internal Use.Repairs and
maintenance are expensed as incurred.



Goodwill represents costs in excess of the fair value of net tangible and identifiable net intangible assets acquired in business
combinations. In accordance
with Statement of Financial Accounting Standards ("SFAS") No. 142,Goodwill and Other Intangible Assets,Covance performs an annual test for
impairment of goodwill and other indefinite lived intangible assets during the fourth quarter. This test is performed by comparing, at the reporting unit level, the carrying value of the reporting
unit to its fair value. Covance assesses fair value based upon its estimate of the present value of the future cash flows that it expects to be generated by the reporting unit. The annual test for
impairment performed for 2006, 2005 and 2004 did not identify any instances of impairment.

2.    Summary of Significant Accounting Policies (Continued)

Intangible
assets with finite lives are amortized on a straight-line basis over their estimated useful lives, which range in term from one to ten years. The Company
periodically evaluates the reasonableness of the estimated useful lives of these intangible assets. See Note 4.



Covance assesses impairment of long-lived assets in accordance with SFAS No. 144,Accounting for the
Impairment or
Disposal of Long-Lived Assets. Assessments of the recoverability of long-lived assets are conducted when events or changes in circumstances occur that
indicate that the carrying value of the asset may not be recoverable. The assessment of possible impairment is based upon the ability to recover the asset from the expected future undiscounted cash
flows of related operations. No events have been identified that caused an evaluation of the recoverability of the long-lived assets for the years ended December 31, 2006, 2005 and
2004.



Covance recognizes revenue either as services are performed or products are delivered, depending upon the nature of the work contracted.
Historically, a majority
of Covance's net revenues have been earned under contracts which range in duration from a few months to two years, but can extend in duration up to five years or longer. Service contracts generally
take the form of fee-for-service or fixed-price arrangements. In the case of fee-for-service contracts, revenue is recognized as services are performed,
based upon, for example, hours worked or samples tested. For long-term fixed-price service contracts, revenue is recognized as services are performed, with performance generally assessed
using output measures, such as units-of-work performed to date as compared to the total units-of-work contracted. Changes in the scope of work generally
result in a renegotiation of contract pricing terms. Renegotiated amounts are not included in net revenues until earned and realization is assured. Estimates of costs to complete are made to provide,
where appropriate, for losses expected on contracts. Costs are not deferred in anticipation of contracts being awarded, but instead are expensed as incurred. In some cases, a portion of the contract
fee is paid at the time the trial is initiated. These advances are deferred and recognized as revenue as services are performed or products are delivered, as discussed above. Additional payments may
be made based upon the achievement of performance-based milestones over the contract duration. Most contracts are terminable by the client either immediately or upon notice. These contracts typically
require payment to Covance of expenses to wind down the study, fees earned to date and, in some cases, a termination fee or a payment to Covance of some portion of the fees or profits that could have
been earned by Covance under the contract if it had not been terminated early. Termination fees are included in net revenues when realization is assured. In connection with the management of
multi-site clinical trials, Covance pays on behalf of its customers fees to investigators, volunteers and other out-of-pocket costs (such as for travel, printing,
meetings, couriers, etc.), for which it is reimbursed at cost, without mark-up or profit. Investigator fees are not reflected in total revenues or expenses where Covance acts in the
capacity of an agent on behalf of the pharmaceutical company sponsor, passing through these costs without risk or reward to Covance. All other out-of-pocket costs are included
in total revenues and expenses.

Unbilled
services are recorded for revenue recognized to date and relate to amounts that are currently unbillable to the customer pursuant to contractual terms. In general, amounts
become billable upon the achievement of milestones or in accordance with predetermined payment schedules. Unbilled services are billable to customers within one year from the respective balance sheet
date. Unearned revenue is recorded for cash received from customers for which revenue has not been recognized at the balance sheet date.

DECEMBER 31, 2006, 2005 AND 2004
(Dollars in thousands, unless otherwise indicated)

2.    Summary of Significant Accounting Policies (Continued)



Cost of revenue includes direct labor and related benefit charges, other direct costs, shipping and handling fees, and an allocation of
facility charges and
information technology costs and excludes depreciation and amortization. Selling, general and administrative expenses consist primarily of administrative payroll and related benefit charges,
advertising and promotional expenses, administrative travel and an allocation of facility charges and information technology costs and excludes depreciation and amortization. Cost of advertising is
expensed as incurred.



Covance uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are
recognized for the
expected future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax bases using enacted tax rates in effect for the year in which the
temporary differences are expected to reverse. The effect on deferred taxes of a change in enacted tax rates is recognized in income in the period when the change is effective. See Note 7.

Covance
maintains a tax reserve for uncertain tax positions which is included in accrued expenses and other current liabilities on the consolidated balance sheets. The balance of this
tax reserve at December 31, 2006 is $8.4 million and relates to exposures for tax matters such as transfer pricing, nexus, deemed dividends, VAT and the allocation of overhead costs
across various Federal, state and foreign income tax jurisdictions. By way of background, an accrual is established at the time an exposure is identified when it is both probable that a liability has
been incurred and the amount of the liability can be reasonably estimated. The amount of the accrual for each item for which an exposure exists is adjusted when either (a) matters are settled
at amounts which are different than the amount included in the reserve or (b) when facts indicate a significant change in either the probability or estimated amount of the potential exposure.
While Covance believes that it has identified all reasonably identifiable exposures and that the reserve it has established for identifiable exposures is appropriate under the circumstances, it is
possible that additional exposures exist and that exposures will be settled at amounts different than the amounts reserved. It is also possible that changes in estimates in the future could cause
Covance to either materially increase or reduce the carrying amount of its tax reserve. Significant activity relating to the reserve for uncertain tax positions which occurred during 2006 included a
$2.5 million reduction in the reserve during the third quarter of 2006 as a result of a
favorable settlement with a foreign tax authority relating to research and development tax credits totaling $1.8 million, as well as exposures as to which it is no longer probable that a
liability exists relating primarily to transfer pricing matters aggregating $0.7 million. Partially offsetting this reduction was an increase in the reserve balance during the fourth quarter of
2006 totaling $2.2 million relating to various state and foreign tax exposures arising in the fourth quarter of 2006 as well as the accrual of additional interest on matters still outstanding.
See "Recently Issued Accounting Standards".

Covance's
historical policy has been to leave its unremitted foreign earnings invested indefinitely outside the United States. Except for the one-time opportunity provided
under the American Jobs Creation Act, pursuant to which Covance repatriated $103 million in accumulated foreign earnings in the fourth quarter of 2005, Covance intends to continue to leave its
unremitted foreign earnings invested indefinitely outside the United States. As a result, taxes have not been provided on any accumulated foreign unremitted earnings as of December 31, 2006.

2.    Summary of Significant Accounting Policies (Continued)



Covance's total comprehensive income represents net income plus the change in the cumulative translation adjustment equity account, and
for 2006, also includes
the adjustment resulting from the adoption of Statement of Financial Accounting Standards No. 158,Employers Accounting for Defined Benefit Pension and Other
Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106 and 132(R),("SFAS 158") to record the under funded status of the Company's defined benefit
postretirement plans on its balance sheet at December 31, 2006.



The Company sponsors several stock-based compensation plans pursuant to which non-qualified stock options and restricted stock awards are
granted to
eligible employees. These plans are described more fully in Note 10.

Through
the year ended December 31, 2005, the Company followed the disclosure-only provisions of Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation,
("SFAS 123"), and, accordingly, accounted for awards under these plans pursuant to the recognition and
measurement principles of Accounting Principles Board Opinion No. 25,Accounting for Stock Issued to Employees, ("APB 25") and related
Interpretations, as permitted by SFAS 123. Under APB 25, compensation expense was recognized in the financial statements relating to awards of stock. However, no compensation expense was
recorded in the financial statements for stock option grants, as all options
have been granted with an exercise price equal to the market value of the underlying common stock on the date of grant. Additionally, no compensation expense was recorded in the financial statements
for shares purchased by employees under the Company's Employee Stock Purchase Plan as that plan was considered to be non-compensatory under APB 25.

Effective
January 1, 2006, the Company adopted the fair value recognition provisions of Statement of Financial Accounting Standards No. 123R, Share-Based Payments, ("SFAS 123R") using the modified
prospective transition method. SFAS 123R revises SFAS 123, supersedes APB 25
and amends Statement of Financial Accounting Standards No. 95,Statement of Cash Flows. Under the modified prospective transition method,
compensation expense is recognized in the financial statements on a prospective basis for (a) all share-based payments granted prior to, but not vested as of January 1, 2006, based upon
the grant-date fair value estimated in accordance with the original provisions of SFAS 123, and (b) share-based payments granted on or subsequent to January 1, 2006,
based upon the grant-date fair value estimated in accordance with the provisions of SFAS 123R. The grant-date fair value of awards expected to vest is expensed on a
straight-line basis over the vesting period of the related awards. Under the modified prospective transition method, results for prior periods are not restated.



Basic EPS is computed by dividing net income available to common stockholders by the weighted average number of shares outstanding during
the period. The
computation of diluted EPS is similar to the computation of basic EPS, except that the denominator is increased to include the number of additional common shares that would have been outstanding if
the dilutive potential common shares had been issued; computed under the treasury stock method in accordance with the requirements of SFAS No. 128,Earnings Per
Share.

2.    Summary of Significant Accounting Policies (Continued)

In
computing diluted EPS for the years ended December 31, 2006, 2005 and 2004, the denominator was increased by 1,196,490 shares, 1,170,734 shares and 2,169,804 shares,
respectively, representing the dilutive effect of stock options outstanding at December 31, 2006, 2005 and 2004, with exercise prices less than the average market price of Covance's common
stock during each respective period. Excluded from the computation of diluted EPS for the year ended December 31, 2006 were options to purchase 12,263 shares of common stock at prices ranging
from $61.26 to $66.86 per share because the exercise prices of such options were greater than the average market price of Covance's common stock during 2006. Excluded from the computation of diluted
EPS for the year ended December 31, 2005 were options to purchase 54,617 shares of common stock at prices ranging from $47.27 to $52.71 per share because the exercise prices of such options
were greater than the average market price of Covance's common stock during 2005. Excluded from the computation of diluted EPS for the year ended December 31, 2004 were options to purchase
331,072 shares of common stock at prices ranging from $35.84 to $41.45 per share because the exercise prices of such options were greater than the average market price of Covance's common stock during
2004.



As discussed in Note 2 "Prepaid Expenses and Other Current Assets", Covance pays on behalf of its customers fees to investigators,
volunteers and other
out-of-pocket costs for which we are reimbursed at cost, without mark-up or profit. In connection with the requirements of Financial Accounting Standards Board
Emerging Issues Task Force Rule No. 01-14 ("EITF 01-14"),Income Statement Characterization of Reimbursements Received for
"Out-of-Pocket" Expenses Incurred, amounts paid to volunteers and other out-of-pocket costs are reflected in operating expenses,
while the reimbursements received are reflected in revenues in the Consolidated Statements of Income. Covance will continue to exclude from revenue and expense in the Consolidated Statements of Income
fees paid to investigators and the associated reimbursement since Covance acts as an agent on behalf of the pharmaceutical company sponsors with regard to investigator payments.



Cash paid for interest for the years ended December 31, 2006, 2005 and 2004 totaled $0.2 million, $0.2 million and
$0.9 million,
respectively. Cash paid for income taxes for the years ended December 31, 2006, 2005 and 2004 totaled $47.8 million, $25.2 million and $21.1 million, respectively. The
change in income taxes payable in the consolidated Statement of Cash Flows for the year ended December 31, 2006 reflects as an operating cash outflow the excess tax benefit received from the
exercise of non-qualified stock options as measured under SFAS 123R of $7.4 million (a corresponding cash inflow of $7.4 million has been reflected in financing cash
flows). The change in income taxes payable in the Consolidated Statement of Cash flows for the years ended December 31, 2005 and 2004 reflects the full tax benefit received from the exercise of
non-qualified stock options of $11.7 million and $16.2 million, respectively, as measured and accounted for under SFAS 123 and APB 25. Pursuant to those standards,
both the reduction in income taxes payable and the increase in equity resulting from the full tax benefit received are reflected in operating cash flows.



In September 2006, the Financial Accounting Standards Board (the "FASB") issued Statement of Financial Accounting Standards
No. 158, Employers' Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106 and 132(R),("SFAS 158"). As of

2.    Summary of Significant Accounting Policies (Continued)

December 31,
2006, Covance has adopted the recognition and disclosure provisions of SFAS 158, which require an employer to recognize the over funded or under funded status of its defined
benefit postretirement plansmeasured as the difference between the fair value of plan assets and the projected benefit obligationas an asset or liability, respectively, in
its balance sheet and to recognize changes in the funded status of the plan in the year in which such changes occur through other comprehensive income. See Note 9 for a discussion of the impact
of the adoption of SFAS 158. SFAS 158 also requires, effective for fiscal years ending after December 15, 2008, that the measurement of the over funded or under funded status of a
plan be made as of the employer's fiscal year end and not as of an earlier measurement date. Covance will be required to conform the measurement dates of its plans to
December 31st for its fiscal year ending December 31, 2008. Covance does not expect this change in measurement dates to have a material impact on its consolidated results
of operations or financial position.

In
September 2006, the FASB issued SFAS No. 157,Fair Value Measurements,("SFAS 157"). SFAS 157, which
applies whenever other standards require (or permit) fair value measurement, defines fair value and provides guidance for using fair value to measure assets and liabilities. SFAS 157 also
requires expanded disclosures about the extent to which companies measure assets and liabilities at fair value, the information used in those measurements and the effect of fair value measurements on
earnings. Covance will be required to adopt SFAS 157, which is effective for fiscal years beginning after November 15, 2007, no later than the quarter beginning January 1, 2008.
Covance is currently in the process of evaluating SFAS 157, and has not yet determined the impact, if any, SFAS 157 will have on its consolidated results of operations or financial
position.

In
June 2006, the FASB issued Interpretation No. 48,Accounting for Uncertainty in Income Taxesan Interpretation of FASB Statement
No. 109("FIN 48"). This authoritative interpretation clarifies and standardizes the manner by which companies will be required to account for uncertain tax positions.
Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006. Covance is required to adopt FIN 48 for its first quarter ending March 31, 2007 and is currently
finalizing its estimate of the impact of adopting FIN 48. Covance currently estimates that the reserve for uncertain tax positions, which totals $8.4 million at December 31, 2006 under
SFAS 109 and SFAS 5, will be between $9.0 million and $12.0 million as calculated under the measurement provisions of FIN 48. The additional reserve for uncertain tax positions,
currently estimated in the range of $0.6 million to $3.6 million, will be recorded in retained earnings in the first quarter of 2007 as a cumulative effect change of adopting a new
accounting pronouncement.

In
June 2006, the Emerging Issues Taskforce reached a consensus on EITF Issue No. 06-3,How Taxes Collected from Customers and Remitted
to Government Authorities Should be Presented in the Income Statement (That Is, Gross versus Net Presentation, ("EITF 06-3") which addresses the
income statement disclosure on taxes assessed by a governmental authority that are directly imposed on a revenue-producing transaction between a seller and a customer, such as sales taxes, use taxes,
value-added taxes and some types of excise taxes. For any such taxes that are reported on a gross basis, EITF 06-3, which is effective for interim periods beginning after
December 15, 2006, requires disclosure of the amounts of those taxes in interim and annual financial statements for each period in which an income statement is presented. Covance currently
accounts for taxes on a net basis, therefore, EITF 06-3 is not expected to have any impact on the Company's consolidated results of operations or financial position.

5.    Equity Method Investees

In March 2004, Covance acquired a 47% minority equity position in Noveprim Limited, a supplier of research products, for a total cost
of
$20.7 million. The excess of the purchase price over the underlying equity in Noveprim's net assets was approximately $13.8 million at the acquisition date. This investment is reflected
in Other Assets on the Consolidated Balance Sheet. During the years ended December 31, 2006 and 2005, Covance recognized income of $1.6 million and $1.3 million, respectively,
representing its share of Noveprim's earnings, less the elimination of profit on inventory purchased from Noveprim Limited and still on hand at Covance at December 31, 2006 and 2005. The
carrying value of Covance's investment in Noveprim as of December 31, 2006 and 2005 was $23.0 million and $21.7 million, respectively.

Covance
has a minority equity position (approximately 21% at December 31, 2006) in Bio-Imaging Technologies, Inc. ("BITI"). BITI uses proprietary medical
imaging technologies to process and analyze medical images, and also provides other services, including the data-basing and regulatory submission of medical images, quantitative data and
text. During the years ended December 31, 2006 and 2005, Covance recognized income of $0.02 million and a loss of $0.5 million, respectively, representing its pro rata share of
BITI's earnings. The carrying value of Covance's investment in BITI at both December 31, 2006 and 2005 was $0.5 million, while the fair market value was $19.0 million and
$7.6 million, respectively.

6.    Acquisitions

In May 2006, Covance acquired the stock of Radiant Research Inc. ("Radiant") in a merger transaction for cash payments
aggregating approximately
$66.6 million (including direct acquisition costs of $0.5 million). The
Radiant acquisition included eight early development clinical sites performing Phase I/IIa clinical trial services. Results of operations for Radiant, which are now part of Covance's Early Development
segment service offering, and the fair value of Radiant's assets and liabilities acquired, are included in Covance's consolidated financial statements beginning in June 2006.

In
May 2006, Covance also acquired certain assets and liabilities of Signet Laboratories, Inc. ("Signet") for cash payments totaling $9.1 million (including direct
acquisition costs of $0.2 million). Signet specializes in the development of monoclonal antibodies and diagnostic assays for cancer, infectious diseases and neurodegenerative diseases. Results
of operations for Signet, which are now part of Covance's Early Development segment service offering, and the fair value of Signet's assets and liabilities acquired, are included in Covance's
consolidated financial statements beginning in June 2006.

The
table below summarizes the preliminary purchase price allocations for the Radiant and Signet acquisitions:

The
purchase price allocations are based upon preliminary estimates for tax matters, using available information and making assumptions management believes are reasonable. Accordingly,
these purchase price allocations are subject to finalization within one year of each acquisition. The goodwill resulting from the Signet acquisition is deductible for tax purposes, while the goodwill
resulting from the merger with Radiant is not deductible for tax purposes.

In
2005, Covance acquired two businesses, the largest of which was the acquisition of GFI Clinical Services (an 80 bed clinical pharmacology business), for cash payments totaling
$7.1 million. The goodwill resulting from these acquisitions aggregated $4.4 million.

7.    Taxes on Income (Continued)

As of December 31, 2006, the non-current deferred tax asset includes $10.7 million related to liabilities not currently
deductible,
recorded in connection with the adoption of SFAS 158, and $4.6 million of expenses not currently deductible, related to stock-based compensation under SFAS 123R.

In
connection with the acquisition of Radiant Research Inc., Covance recorded a net deferred tax asset of $6.6 million primarily relating to acquired net operating loss
carryforwards. The utilization of the net loss carryforwards totaling $16.7 million as of December 31, 2006 is subject to an annual limitation under Internal Revenue Code
§382 and will expire at various dates through 2026. It is expected that the
entire net operating loss carryforwards will be realized and, accordingly, no valuation allowance has been provided at December 31, 2006.

At
December 31, 2006, deferred tax assets of $8.2 million have been recorded on $27.3 million of net operating tax loss carryforwards arising in the United Kingdom
from the current recognition of deductions for qualified research and development expenditures and accelerated depreciation. It is expected that the entire net operating loss carryforwards, which do
not expire, will be realized and, accordingly, no valuation allowance has been provided.

On
October 22, 2004, the American Jobs Creation Act of 2004 (the "Act") was signed into law. Among other things, the Act provided a temporary incentive for multi-national
companies to repatriate previously unremitted foreign earnings by allowing companies a special one-time tax deduction equal to 85% of qualified foreign earnings that were repatriated.
During the fourth quarter of 2005, Covance repatriated $103 million in foreign earnings under the Act, which resulted in the recording of an income tax charge of $4.4 million (or
$0.07/diluted share).

Covance
currently provides income taxes on the earnings of foreign subsidiaries to the extent those earnings are taxable or are expected to be remitted. Covance's historical policy has
been to leave its unremitted foreign earnings invested indefinitely outside the United States. Except for the amounts repatriated in the fourth quarter of 2005 under the Act, Covance intends to
continue to leave its unremitted foreign earnings invested indefinitely outside the United States. It is not practical to estimate the amount of additional tax that might be payable if such
accumulated earnings were remitted. Additionally, if such accumulated earnings were remitted, certain countries impose withholding taxes that, subject to certain limitations, are available for use as
a tax credit against any Federal income tax liability arising from such remittance. As a result, taxes have not been provided on the remaining accumulated foreign unremitted earnings totaling
approximately $195 million at December 31, 2006.

8.    Credit Facility

Covance has a $75.0 million revolving credit facility (the "Credit Facility"), which expires in June 2009. At both
December 31, 2006 and
2005, there were no outstanding borrowings under the Credit Facility. At December 31, 2006 and 2005, there were $0.8 million and $1.5 million, respectively, of outstanding letters
of credit under the Credit Facility.

At
December 31, 2006, Covance was in compliance with the terms of the Credit Facility, including all financial covenants. Commitment fees paid during 2006, 2005 and 2004, which
under the Credit Facility are
15 basis points on the undrawn balance, approximated $0.1 million, $0.1 million, and $0.4 million, respectively. The Credit Facility is collateralized by guarantees of certain of
Covance's domestic subsidiaries and a pledge of 65 percent of the capital stock of certain of Covance's foreign subsidiaries.

9.    Employee Benefit Plans

Covance sponsors various pension and other post-retirement benefit plans. Effective December 31, 2006, Covance adopted Statement of
Financial
Accounting Standards No. 158,Employers Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106 and
132(R),("SFAS 158"). SFAS 158 requires an employer to recognize the over funded or under funded status of its defined benefit postretirement
plansmeasured as the difference between the fair value of plan assets and the projected benefit obligationas an asset or liability, respectively, in its balance sheet and to
recognize changes in the funded status of the plan through other comprehensive income (in the year such changes occur). The impact of adopting SFAS 158 on our consolidated balance sheet at
December 31, 2006 was an increase in non-current liabilities of $21.3 million, reflecting the under funded status of the plans, a reduction in other assets of
$12.8 million, from the elimination of the prepaid pension asset which existed under SFAS 87, the recording of a long-term deferred tax asset of $10.7 million and a reduction
in the other comprehensive income equity account of $23.4 million.



Covance sponsors two defined benefit pension plans for the benefit of its employees at two United Kingdom subsidiaries and one defined
benefit pension plan for
the benefit of its employees at a German subsidiary, all of which are legacy plans of previously acquired companies. Benefit amounts for all three plans are based upon years of service and
compensation. The German plan is unfunded and has a measurement date of September 30, while the UK pension plans are funded and have a measurement date of December 31. Covance's funding
policy has been to contribute annually a fixed percentage of the eligible employee's salary at least equal to the local statutory funding requirements. The components of net periodic pension cost for
these plans for 2006, 2005 and 2004 are as follows:

The
weighted average expected long term rate of return on the assets of the UK pension plans is based on the target asset allocation and the average rate of growth expected for the
asset classes invested. The weighted average rate of expected growth is derived from a combination of historic returns, current market indicators, the expected risk premium for each asset class over
the risk- free rate and the opinion of professional advisors.

The
accumulated benefit obligation for the UK pension plans was $116,236 and $96,923 at December 31, 2006 and 2005, respectively. The accumulated benefit obligation for the
German plan was $5,725 and $4,448 at December 31, 2006 and 2005, respectively.

The
investment policies for the UK pension plans are set by the plan trustees, based upon the guidance of professional advisors and after consultation with the Company, taking into
consideration the plans' liabilities and future funding levels. The trustees have set the long-term investment policy largely in accordance with the asset allocation of a broadly
diversified investment portfolio. Assets are invested within the target ranges as follows:

Equity securities

51%61%Debt securities

31%44%Real estate

Investments
are made in pooled investment funds. Pooled investment fund managers are regulated by the Financial Services Authority in the UK and operate under terms which contain
restrictions on the way in which the portfolios are managed and require the managers to ensure that suitable internal operating procedures are in place. The trustees have set performance objectives
for each fund manager and routinely monitor and assess the managers' performance against such objectives.

Covance
expects to contribute $3,430 to its UK plans in 2007. No contributions are expected to be made to the German plan, since that plan is unfunded.

In addition to these foreign defined benefit pension plans, Covance also has a non-qualified Supplemental Executive Retirement Plan
("SERP"). The
SERP, which is not funded, is intended to provide retirement benefits for certain executive officers of Covance. Benefit amounts are based upon years of service and compensation of the participating
employees. The measurement date for the SERP is November 30. The components of net periodic pension cost for the years ended December 31, 2006, 2005 and 2004 are as follows:

Covance also sponsors a post-employment retiree health and welfare plan for the benefit of eligible employees at certain U.S. subsidiaries
who retire
after satisfying service and age requirements. This plan is funded on a pay-as-you-go basis and the cost of providing these benefits is shared with the retirees.

A one-percentage-point increase or decrease in the assumed health care cost trend rate would not impact the net service and interest
cost components of the net periodic post-retirement benefit cost or the post-retirement benefit obligation since future increases in plan costs are paid by participant
contributions. Covance expects to contribute $574 to the post-employment retiree health and welfare plan in 2007.

In
December 2003, the President of the United States signed into law the Medicare Prescription Drug Improvement and Modernization Act of 2003 (the "Prescription Drug Act"). The
Prescription Drug Act introduces a prescription drug benefit beginning in 2006 under Medicare (Medicare Part D) as well as a Federal subsidy to sponsors of retiree health care benefit plans
that provide a benefit that is at least actuarially equivalent to Medicare Part D. Final regulations on determining actuarial equivalency were issued on January 21, 2005. Covance
completed its review of the final regulations during the first quarter of 2005 and determined that the benefits provided under its postretirement benefit plan are actuarially equivalent to Medicare
Part D. The effect of the Prescription Drug Act was first incorporated into the measurement of plan obligations at November 30, 2005, resulting in a $1.0 million reduction of the
accumulated benefit obligation. The Federal subsidy resulted in a $0.1 million reduction to net periodic benefit costs for 2006.

9.    Employee Benefit Plans (Continued)



U.S. employees are eligible to participate in Covance's 401(k) plan, while employees in international locations are eligible to
participate in either defined
benefit or defined contribution plans, depending on the
plan offered at their location. Aggregate Covance contributions to its various defined contribution plans totaled $17.1 million, $14.6 million and $14.0 million for 2006, 2005 and
2004, respectively.

10.    Stockholders' Equity



Covance is authorized to issue up to 10.0 million shares of Series Preferred Stock, par value $1.00 per share (the "Covance Series
Preferred Stock"). The
Covance Board of Directors has the authority to issue such shares from time to time, without stockholder approval, and to determine the designations, preferences, rights, including voting rights, and
restrictions of such shares, subject to the Delaware General Corporate Laws. Pursuant to this authority, the Covance Board of Directors has designated 1.0 million shares of the Covance Series
Preferred Stock as Covance Series A Preferred Stock. No other class of Covance Series Preferred Stock has been designated by the Board. As of December 31, 2006, no Covance Series
Preferred Stock has been issued or is outstanding.



Covance's Board of Directors may declare dividends on the shares of Covance common stock out of legally available funds (subject to any
preferential rights of
any outstanding Covance Series Preferred Stock). However, Covance has no present intention to declare dividends, but instead intends to retain earnings to provide funds for the operation and expansion
of its business.



In February 2003, the Covance Board of Directors authorized the repurchase of 3.0 million shares under Covance's stock
repurchase program. In
June 2004, the Covance Board of Directors authorized the repurchase of an additional 3.0 million shares under Covance's stock repurchase program. For the years ended December 31,
2006, 2005, and 2004, Covance repurchased 0.4 million shares, 1.2 million shares, and 3.5 million shares, respectively, under Covance's stock repurchase program. At
December 31, 2006 there were 0.3 million shares remaining for purchase under the 2004 authorization. Covance also reacquires shares of its common stock in connection with certain
employee benefit plans when employees tender shares either in connection with reload stock options or to satisfy income tax withholdings associated with the vesting of stock awards. The following

10.    Stockholders' Equity (Continued)



In June 2002, Covance's Board of Directors adopted the 2002 Employee Stock Option Plan (the "2002 ESOP"). The 2002 ESOP will expire
on June 24,
2012. The 2002 ESOP authorizes the Compensation and Organization Committee of the Board of Directors (the "Compensation Committee"), or such committee as is appointed by the Covance Board of
Directors, to administer the 2002 ESOP, to grant awards to employees of Covance or entities in which Covance has a controlling or significant interest, except that officers as defined in
Rule 16(a)-1(f) of the Securities Exchange Act of 1934, and members of the Board of Directors are not eligible to receive awards. The 2002 ESOP authorizes the Compensation Committee
to grant the following awards to eligible employees: options to purchase common stock and stock appreciation rights. The exercise period for stock options granted under the 2002 ESOP is determined by
the Compensation Committee at the time of grant, and is generally ten years from the date of grant. The vesting period for stock options granted under the 2002 ESOP is determined by the Compensation
Committee at the time of grant and is generally two years from the date of grant. No stock appreciation rights have ever been granted under the 2002 ESOP. The number of shares of Covance common stock
initially available for grant under the 2002 ESOP totaled 5.9 million. The Company issues authorized but previously unissued shares when options are exercised. At December 31, 2006,
there were approximately 3.1 million shares remaining available for grants or awards under the 2002 ESOP.

In
May 2002, Covance's shareholders approved the 2002 Employee Equity Participation Plan (the "2002 EEPP") in replacement of the 2000 Employee Equity Participation Plan (the
"2000 EEPP"). The 2002 EEPP became effective on May 7, 2002 and will expire on May 6, 2012. The 2002 EEPP authorizes the Compensation Committee, or such committee as is appointed by the
Covance Board of Directors, to administer the 2002 EEPP, to grant awards to employees and consultants of Covance or entities in which
Covance has a controlling or significant interest. The 2002 EEPP authorizes the Compensation Committee to grant the following awards to eligible employees: options to purchase common stock; stock
appreciation rights; and other stock awards either singly or in combination. The exercise period for stock options granted under the 2002 EEPP is determined by the Compensation Committee at the time
of grant, and is generally ten years from the date of grant. The vesting period for stock options and stock awards granted under the 2002 EEPP is determined by the Compensation Committee at the time
of grant. Generally, options vest over a three year period for senior executives and over a two year period for all other optionees. Stock awards generally vest over a three year period for all
employees. The number of shares of Covance common stock initially available for grant under the 2002 EEPP totaled approximately 3.25 million plus approximately 0.9 million shares
remaining available under the 2000 EEPP at the time the 2002 EEPP was approved. Effective upon approval of the 2002 EEPP, no further grants or awards were permitted under the 2000 EEPP. All grants and
awards under the 2000 EEPP remaining outstanding are now administered and paid in accordance with the provisions of the 2000 EEPP out of shares issuable under the 2002 EEPP. The Company issues
authorized but previously unissued shares when options are exercised or stock awards vest. At December 31, 2006 there were approximately 3.7 million shares remaining available for grants
or awards under the 2002 EEPP.

Effective
January 1, 2006, the Company adopted the fair value recognition provisions of SFAS 123R using the modified prospective transition method. SFAS 123R
revises SFAS 123, supersedes APB 25 and amends Statement of Financial Accounting Standards No. 95,Statement of Cash Flows. Under the
modified prospective transition method, compensation expense is recognized in the financial statements on a prospective basis for (a) all share-based payments granted prior to, but not vested
as of January 1, 2006, based upon the grant-date fair value estimated in accordance with the original provisions of SFAS 123, and (b) share-based payments granted on
or subsequent to January 1, 2006, based upon the grant-date fair value estimated in

accordance
with the provisions of SFAS 123R. The grant-date fair value of awards expected to vest is expensed on a straight-line basis over the vesting period of the
related awards. Under the modified prospective transition method, results for prior periods are not restated.

As
a result of the adoption of SFAS 123R, both income from operations and income before taxes for the year ended December 31, 2006 include incremental stock-based
compensation expense of $15.5 million. For the year ended December 31, 2006, the after tax impact of this incremental stock-based compensation expense on net income, basic and diluted
earnings per share was $10.6 million, $0.17 and $0.16, respectively. Results of operations for the year ended December 31, 2006 include $21.5 million ($14.5 million net of
tax benefit of $7.0 million) of total stock-based compensation expense, $7.0 million of which has been included in cost of revenue and $14.5 million of which has been included in
selling, general and administrative expenses.

Prior
to January 1, 2006, Covance followed the disclosure-only provisions of SFAS 123 and, accordingly, accounted for awards under its share based compensation
plans pursuant to the recognition and measurement principles of APB 25 and related Interpretations, as permitted by SFAS 123. Under APB 25, compensation expense was recognized in the financial
statements for the fair value of stock awards. However, no compensation expense was recorded in the financial statements for stock option grants, as all options have been granted with an exercise
price equal to the market value of the underlying common stock on the date of grant. Additionally, no compensation expense was recorded in the financial statements for shares purchased by employees
under the Company's Employee Stock Purchase Program as that plan was
considered to be non-compensatory under APB 25. The following table illustrates the effect on net income and earnings per share for the years ended December 31, 2005 and 2004 had
Covance applied the fair value recognition provisions of SFAS 123 to all of its stock-based employee compensation plans.

OptionsThe grant-date fair value of stock option awards is estimated using an option
pricing model. For stock options granted prior to January 1, 2006, the Company used the Black-Scholes-Merton option pricing formula to estimate the grant-date fair value of such
awards. For stock options granted on or subsequent to January 1, 2006, the Company is using the Lattice-Binomial option pricing formula to estimate the grant-date fair value of
stock option awards. The Company changed to the Lattice-Binomial option pricing formula as it believes such formula may result in a better estimate of fair value than the Black-Scholes-Merton formula.
In order to estimate the grant-date fair value, option pricing models require the use of estimates and assumptions as to (a) the expected term of the option, (b) the expected
volatility of the price of the underlying stock, (c) the risk-free interest rate for the expected term of the option and (d) pre-vesting forfeiture rates. The
expected term of the option is based upon the contractual term, taking into account
expected employee exercise and expected post-vesting employment termination behavior. The expected volatility of the price of the underlying stock is based upon the historical volatility
of the Company's stock computed over a period of time equal to the expected term of the option. The risk free interest rate is based upon the implied yields currently available from the U.S. Treasury
zero-coupon yield curve for issues with a remaining duration equal to the expected term of the option. Pre-vesting forfeiture rates are estimated based upon past voluntary
termination behavior and past option forfeitures.

The
following table sets forth the weighted-average assumptions used to calculate the fair value of options granted for the years ended December 31, 2006, 2005 and 2004:

Cash
proceeds from stock options exercised during the years ended December 31, 2006, 2005 and 2004 totaled $28.4 million, $28.8 million and
$57.9 million, respectively. Prior to the adoption of SFAS 123R, the Company presented the tax benefit of deductions resulting from the exercise of stock options as an operating cash
flow in the Statements of Cash Flows in accordance with SFAS 123 and APB 25. For the years ended December 31, 2005 and 2004, the tax benefit realized and included in operating cash flows
totaled $11.7 million and $16.2 million, respectively. SFAS 123R requires that the cash flows resulting from tax benefits realized on tax deductions "in excess of" the
compensation expense recognized (either in the financial statements or the pro forma footnote disclosures) for stock options exercised in the period be classified as a financing cash flow. The "excess
tax benefit" classified as a financing cash inflow during the year ended December 31, 2006 was $7.4 million and would have been classified as an operating cash inflow under
SFAS 123. The actual tax benefit realized on stock options exercised during the year ended December 31, 2006 was $12.8 million. The difference between the actual tax benefit
received and the "excess
tax benefit" computed in accordance with SFAS 123R of $5.4 million continues to be classified as an operating cash inflow.

Restricted Stock AwardsRestricted stock awards are granted subject to certain restrictions, including in some cases service
conditions (restricted stock) and in other cases service and performance conditions (performance-based shares). The grant-date fair value of restricted stock and performance-based share
awards, which has been determined based upon the market value of Covance's shares on the grant date, is expensed over the vesting period.

restricted
stock awards which vested during 2006 and 2005 was $0.1 million and $1.3 million, respectively, with no restricted stock awards vesting in 2004.

Employee Stock Purchase PlanCovance also has an employee stock purchase plan (the "ESPP") pursuant to which Covance may make
available for sale to employees shares of its common stock at a price equal to 85% of the lower of the market value on the first or last day of each calendar quarter. The ESPP, administered by the
Compensation Committee, is intended to give Covance employees the opportunity to purchase shares of Covance common stock through payroll deductions. A maximum of 3.0 million shares may be
purchased by Covance employees under the ESPP. During 2006, 2005 and 2004, a total of 92,927 shares, 102,501 shares and 116,701 shares of common stock, respectively, were issued under the ESPP. At
December 31, 2006, there were approximately 0.9 million shares remaining for purchase under the ESPP.

11.    Commitments and Contingencies

Covance is obligated under non-cancelable operating leases, primarily for its offices and laboratory facilities. These leases generally
contain
customary scheduled rent increases or escalation clauses and renewal options. Covance is also obligated under outsourcing agreements related to certain aspects of its information technology and human
resources support functions and purchase commitments related to the completion of ongoing facility expansions, both of which are reflected under the purchase obligations caption in the table below.
Actual amounts paid under these outsourcing agreements could be higher or lower than the amounts shown below as a result of changes in volume and other variables. In addition, early termination of
these outsourcing agreements by Covance could result in the payment of termination fees which are not reflected in the table below.

12.    Segment Information

Covance has two reportable segments: early development and late-stage development. Early development services, which includes Covance's
preclinical
and clinical pharmacology service capabilities, involve evaluating a new compound for safety and early effectiveness as well as evaluating the absorption, distribution, metabolism and excretion of the
compound in the human body. It is at this stage that a pharmaceutical company, based on available data, will generally decide whether to continue further development of a drug. Late-stage
development services, which include Covance's central laboratory, clinical development, cardiac safety services, periapproval and market access services, are geared toward demonstrating the clinical
effectiveness of a compound in treating certain diseases or conditions,
obtaining regulatory approval and maximizing the drug's commercial potential. The accounting policies of the reportable segments are the same as those described in Note 2.
