PART I

ITEM 1.  BUSINESS

Overview

LabOne, Inc., a Missouri corporation, provides risk assessment services for the insurance industry, laboratory testing services for the healthcare industry and substance abuse testing services for employers and third party administrators.  LabOne, Inc. and its wholly-owned subsidiaries Osborn Group, Inc. (Osborn), Lab One Canada Inc., Systematic Business Services, Inc. (SBSI) and ExamOne World Wide, Inc. (ExamOne), are hereinafter collectively referred to as either LabOne or the Company.

LabOne's Risk Assessment division provides underwriting and claims support services including teleunderwriting, specimen collection and paramedical examinations, laboratory testing, telephone inspections, motor vehicle reports, claims investigation services and medical information retrieval to the insurance industry. The laboratory tests performed by the Company are specifically designed to assist an insurance company in objectively evaluating the mortality and morbidity risks posed by policy applicants.  The majority of the testing is performed on specimens of individual life insurance policy applicants but also includes specimens of individuals applying for individual and group medical and disability policies.

LabOne's Clinical division includes laboratory testing services for the healthcare industry as an aid in the diagnosis and treatment of patients.  LabOne operates a highly automated and centralized laboratory, which the Company believes has significant economic advantages over other conventional laboratory competitors.  LabOne markets its clinical testing services to managed care companies, insurance companies, self-insured groups and physicians.

LabOne's Clinical division also includes substance abuse testing services provided to employers who adhere to drug screening guidelines.  LabOne is certified by the Substance Abuse and Mental Health Services Administration to perform substance abuse testing services for federally regulated employers and currently markets these services throughout the country to both regulated and nonregulated employers.  The Company's rapid turnaround times and multiple testing options help clients reduce downtime for affected employees and meet mandated drug screening guidelines.

Purchase of Osborn Group, Inc.

Effective August 31, 2001, LabOne purchased all of the outstanding capital stock of Osborn Group, Inc., (Osborn) a leading provider of laboratory testing and other risk assessment services to the life insurance industry.  Intellisys, Inc., Applied BioConcepts Inc. and Osborn Laboratories (Canada) Inc., wholly owned subsidiaries of Osborn Group, were included in the purchase. As a result of the transaction, LabOne was able to consolidate Osborn's testing and other operations to LabOne's Lenexa, Kansas facility. With this acquisition, LabOne has a combined revenue base of $250 million and will annually perform laboratory testing for approximately 10 million individuals for its risk assessment, healthcare and substance abuse.  Due to operational overlap, LabOne expects to generate up to $10 million of annual cost savings from the acquisition.

To fund the acquisition and related expenses of the transaction, Welsh, Carson, Anderson & Stowe, IX, L.P. and related purchasers (WCAS) invested a total of $50 million in convertible preferred stock and subordinated debt in LabOne pursuant to a Securities Purchase Agreement dated August 31, 2001.  See "Liquidity" for further discussion of the issued securities.

Services Provided by the Company

Risk Assessment Services:

Insurance companies require an objective means of evaluating the insurance risk posed by policy applicants in order to establish the appropriate level of premium payments, or to determine whether to issue a policy.  Because decisions of this type are based on statistical probabilities of mortality and morbidity, insurance companies generally require quantitative data reflecting the applicant's general health.  LabOne utilizes standardized specimen collection, medical questionnaires and laboratory testing, tailored to the needs of the insurance industry and reported in a uniform format.  This information provides insurance companies with a consistent and efficient means of evaluating the mortality and morbidity risks posed by policy applicants.

When an individual applies for insurance, a paramedical company is contacted to arrange for collection of a blood and/or urine specimen.  ExamOne's paramedical representatives perform paramedical examinations and collect specimens from individual insurance applicants using LabOne's custom-designed collection kits and containers.  Insurance agents also collect oral fluid or urine specimens using LabOne's kits.  These kits and containers are delivered to LabOne's laboratory via overnight delivery services or mail, bar coded for identification and tested according to each insurance company's specifications.

LabOne's insurance laboratory testing services consist of certain specimen profiles that provide insurance companies with specific information that may indicate liver or kidney disorders, diabetes, the risk of cardiovascular disease, bacterial or viral infections and other health risks.  The Company also offers tests to detect the presence of antibodies to human immunodeficiency virus (HIV).  Insurance companies generally offer a premium discount for nonsmokers and often rely on testing to determine whether an applicant is a user of tobacco products.  Standardized laboratory testing can be used to verify responses on a policy application to such questions as whether the applicant is a user of tobacco products, certain controlled substances or certain prescription drugs.  Cocaine use has been associated with increased risk of accidental death and cardiovascular disorders, and as a result of cocaine abuse in the United States and Canada, insurance companies test most policy applicants to detect its presence.  Therapeutic drug testing also detects the presence of certain prescription drugs that are being used by an applicant to treat a life-threatening medical condition that may not be revealed by a physical examination.

CaseView, LabOne's proprietary requirements management software, allows underwriters to order laboratory testing and other services, check the status of those requests, review results electronically, request add-on tests or services based on the results and to manage the underwriting services they order through LabOne and its subsidiaries.  With the Osborn acquisition, the Company also offers IntelliNet, a second network/software product that provides connectivity and case management capabilities for insurance clients.  The integration of the best features of these products into one superior product should benefit insurance clients and result in cost savings to the Company.

LabOne assists with the administration and tracking of data for applicants during the information gathering process.  The Company can obtain medical records or attending physician statements so underwriters can review the complete medical history of applicants.  Inspection reports, either by telephone or performed in the field, provide additional applicant information quickly and cost-effectively.  Motor vehicle reports are ordered automatically based on insurance company specifications or on demand by the underwriter.  The Company can collect, process and provide imaged reports of these various pieces of information electronically through LabOne NET® directly to the insurance company's underwriting department.

Clinical Services:

Healthcare laboratory tests are generally requested by physicians to diagnose and monitor diseases and other medical conditions through the detection of substances in blood and other specimens.  Laboratory testing is generally categorized as either clinical testing, which is performed on bodily fluids including blood and urine, or anatomical pathology testing, which is performed on tissue specimens.  Clinical and anatomical pathology tests are frequently performed as part of routine physical examinations and hospital admissions in connection with the diagnosis and treatment of illnesses.  The most frequently requested tests include blood chemistry analyses, blood cholesterol level tests, urinalyses, blood cell counts, PAP smears and AIDS-related tests.

Healthcare specimens are collected at the physician's office or other specified sites.  Contracted couriers pick up the specimens and deliver them to local airports for express transport to the Kansas laboratory.  Specimens are bar coded for identification and processed.  The Company's testing menu includes the majority of tests requested by its clients.  Tests not performed at LabOne are sent to reference laboratories for testing, and the results of these outsourced tests are transmitted into the Company's computer system for reporting along with the results completed by LabOne.

The Company has established the Lab Card® Program as a method of marketing outpatient laboratory services directly to payors.  The Lab Card Program is marketed to self-insured groups and insurance companies, and provides laboratory testing at reduced rates as compared to traditional laboratories.  It uses a unique benefit design that shares the cost savings with the patient, creating an incentive for the patient to direct laboratory work to LabOne.  Under the Program, the patient generally incurs no out-of-pocket expense when the Lab Card is used, and the insurance company or self-insured group receives substantial savings on its laboratory charges.

Additionally, LabOne has several exclusive arrangements with managed care organizations, including Coventry Healthcare of Kansas City, BlueCross BlueShield of Tennessee and BlueCross BlueShield of Kansas City.  With these arrangements, the managed care organizations direct testing for all of their members through LabOne.

LabOne markets substance abuse testing to large employers, third party administrators and occupational health providers.  Certification by the Substance Abuse and Mental Health Services Administration enables the Company to offer substance abuse testing services to federally regulated industries.

Specimens for substance abuse testing are typically collected by independent agencies that use LabOne's forms and collection supplies.  Specimens are sealed with bar coded, tamper-evident seals and shipped overnight to the Company.  Automated systems monitor the specimens throughout the screening and confirmation process.  Negative results are typically reported within 12 hours of accessioning in the laboratory.  Initial positive specimens are verified by the gas chromatography/mass spectrometry method, and results are generally reported within 72 hours of accessioning in the laboratory.  Results can be transmitted electronically to the client's secured computer, printer or fax machine, or the client can use LabOne's LabLink Dial-In software to retrieve, store, search and print its drug testing results.

Operations

LabOne

The Company's operations are designed to facilitate the testing of a large number of specimens and to report the results to clients, generally within 24 hours of receipt of the specimens.  The Company has internally developed, custom-designed laboratory and business processing systems.  It is a centralized network system that provides an automated link between LabOne's testing equipment, data processing equipment and clients' computer systems.  This system offers LabOne's clients the ability to customize their initial testing and follow-up testing requirements by several parameters to best meet their needs.

As a result of the significant number of tests it has performed over the past several years, LabOne has compiled and maintains a large statistical database of test results.  These summary statistics are useful to the actuarial and underwriting departments of an insurance client in comparing that client's test results to the results obtained by the Company's entire client base.  Company-specific and industry-wide reports are frequently distributed to clients on subjects such as coronary risk analysis, cholesterol and drugs of abuse.  Additionally, the Company's statistical engineering department is capable of creating customized reports to assist managed care entities or employers in disease management, for HEDIS reporting and utilization tracking to help manage healthcare costs.

The Company considers the confidentiality of its test results and other personal data processed to be of primary importance and has established procedures to ensure that this information remains secure and confidential.

All of the reagents and materials used by the Company in conducting its testing are commercially purchased and most are readily available from multiple sources.

Regulation

LabOne's business is subject to significant federal and state regulation.  Changes in regulation may significantly increase the costs of doing business.

LabOne is licensed under the Clinical Laboratory Improvement Amendments of 1988 and maintains additional licenses for clinical testing with all states where such licenses are required.

LabOne is certified by the Substance Abuse and Mental Health Services Administration to perform testing to detect drugs of abuse in federal employees and in workers governed by federal regulations.  The Company is subject to federal and state regulation relating to the handling and disposal of medical waste and hazardous waste and federal regulation by the Food and Drug Administration, the Occupational Safety and Health Administration related to workplace safety and several agencies related to the transportation of laboratory specimens.

Congress has enacted the Health Insurance Portability and Accountability Act of 1996 (HIPAA).  Pursuant to HIPAA, LabOne will be required to maintain administrative, technical, and physical safeguards to protect the security and confidentiality of healthcare information against unauthorized uses or disclosures.  LabOne has appointed both a security officer and a privacy officer who are leading efforts to meet the upcoming requirements, the most significant of which is the April 2003 compliance date for the privacy regulations.  Compliance with the HIPAA requirements have already, and will continue to, require significant resources.

Compliance Program; Quality Assurance

LabOne's Regulatory Affairs department oversees quality assurance programs to ensure that accurate and reliable test results are released to clients.  This is accomplished by incorporating both internal and external quality improvement programs in each area of the laboratory.  In addition, quality improvement specialists share the responsibility with all LabOne employees of an ongoing commitment to quality and safety in all laboratory operations.  Internal quality and education programs are designed to identify opportunities for improvement in laboratory services and to meet all required safety, training and education issues.  These programs help ensure the reliability and confidentiality of test results.

Procedure manuals in all areas of the laboratory help maintain uniformity and accuracy and meet regulatory guidelines.  Tests on control samples with known results are performed frequently to maintain and verify accuracy in the testing process.  Complete documentation provides record keeping for employee reference and meets regulatory requirements.  All employees are thoroughly trained to meet standards mandated by OSHA in order to maintain a safe work environment.  Superblind Testing Service® controls are used to challenge every aspect of service at LabOne from specimen arrival to account setup, testing, reporting and through final billing.  Approximately 500 sample kits are prepared and submitted anonymously each month.  These samples have at least 15 different indicators each representing over 7,500 challenges to the testing, handling and reporting procedures.

Specimens requiring special handling are evaluated and verified by control analysis personnel.  A computer edit program is used to review and verify clinically abnormal results and all positive HIV antibody and drugs-of-abuse records.  As an external quality assurance program, LabOne participates in a number of proficiency programs established by the College of American Pathologists, the American Association of Bioanalysts and the Centers for Disease Control.

LabOne has appointed a Chief Compliance Officer and 14 co-compliance officers representing corporate security, operations, legal, human resources, regulatory affairs, billing, sales, finance, administration and information systems and technology functions within LabOne.  Additionally, the Company has developed the LabOne Compliance Plan, based on the Model Compliance Plan recommended by the Office of Inspector General of the Department of Health and Human Services, to ensure compliance with anti-fraud and abuse laws and rules governing federally-financed reimbursement for laboratory testing services.

Sales and Marketing

LabOne's client base consists of insurance companies, managed care organizations, third party administrators, occupational health clinics and employers primarily in North America.  The Company believes that its ability to provide prompt and accurate results on a cost-effective basis, and its responsiveness to customer needs have been important factors in servicing existing business.

All of the Company's sales representatives for the risk assessment market have significant business experience in the insurance industry or clinical laboratory-related fields.  These representatives call on major clients several times each year, usually meeting with a medical director or vice president of underwriting.  An important part of the Company's marketing effort is directed toward providing its existing clients and prospects with information pertaining to the actuarial benefits of, and trends in, laboratory testing.  The Company's sales representatives and its senior management also attend and sponsor insurance industry underwriters' and medical directors' meetings.

The sales representatives for the healthcare industry are experienced in the healthcare benefit market or clinical laboratory-related fields, and each currently works in a specific geographic area.  Marketing efforts are directed at insurance carriers, self-insured employers and trusts, third party benefit administrators, physician practices and other organizations nationwide.

Substance abuse marketing efforts are primarily directed at Fortune 1000 companies, occupational health clinics and third party administrators.  The Company's strategy is to offer quality service at competitive prices.  The sales force focuses on LabOne's ability to offer multiple reporting methods, next-flight-out options, dedicated client service representatives and rapid reporting of results.

Competition

The Company believes that the risk assessment services market in the United States and Canada is a $1 billion industry.  The Company serves approximately 20% of this market.  The primary competition in the market includes Hooper Holmes, Inc. and Examination Management Services, Inc.  In this market, LabOne has developed long-term client relationships and a reputation for providing quality services at competitive prices tailored specifically to the insurance industry's needs.  The risk assessment market continues to be highly competitive with the primary focus on the ability to provide rapid, comprehensive and high quality information services.  The Company continues to develop innovative data management services and technological solutions that differentiate its products from competitors.  These services and solutions enable LabOne's clients to expedite the underwriting and claims processes, saving time and reducing underwriting costs.

During 2000, LabOne was selected by State Farm Insurance Company to be its national account manager for the collection and testing of specimens from its life and health insurance applicants. In July of 2001, the Company completed the implementation of this unique national account management program in all 50 states.  The Company believes the success of this implementation can serve as a validated model for other such programs managed by the Company in the future, and provides a competitive advantage.  Due to this arrangement, total revenue recognized by LabOne from State Farm for 2001 exceeded 10% of total revenue.  The loss of the State Farm account would have a material adverse effect on the Company.

The outpatient laboratory testing segment of the clinical market is a $25 billion industry, which is highly fragmented and very competitive.  The Company faces competition from numerous independent clinical laboratories and hospital-owned or physician-owned laboratories.  Many of the Company's competitors are significantly larger and have substantially greater financial resources than LabOne.  The Company has established a solid client base through the use of Lab Card® and exclusive arrangements with managed care entities to provide laboratory services and information reporting.

LabOne competes in the substance abuse testing segment nationwide, presently estimated to be a $1.0 billion industry.  There are currently 56 laboratories certified by the Substance Abuse and Mental Health Services Administration.  The Company's major competitors are the major clinical chains, Laboratory Corporation of America and Quest Diagnostics, which collectively constitute approximately two-thirds of the substance abuse testing market.  The Company's focus is fast turnaround with high-quality, low-cost service, with a strategic position of offering oral fluid based drug screening in the pre-employment market.

LabOne's business plan is to be the premier provider of high-quality, cost effective laboratory and information services to insurance companies, self-insured employers, and physician practices.  The Company feels that its superior quality and centralized, quality controlled processes and low-cost operating structure enable it to compete effectively in this market.

Technology Development

The technology development department evaluates new commercially available tests and technologies, or develops new assays, and compares them to competing products in order to select the most accurate and efficient laboratory procedures.  Additionally, LabOne's scientists present findings to clients to aid them in choosing the best tests available to meet their requirements.  Total technology development expenditures are not considered significant to the Company as a whole.

Employees

As of February 28, 2002, the Company had 1,625 employees, including 77 part-time employees, representing an increase of 259 employees from the same time in 2001.  None of the Company's employees is represented by a labor union.  The Company believes its relations with employees are good.

ITEM 2.  PROPERTIES

The Company's principal operations are located on 54 acres in Lenexa, Kansas, approximately 15 miles from Kansas City, Missouri.  Its 268,000 square foot, custom-designed facility houses the Company's laboratory, administrative and warehouse functions.  The facility is owned by the Company and financed through industrial revenue bonds issued by the City of Lenexa, Kansas.  The remaining balance on the bonds is $14.5 million.  The laboratory has certain enhancements that improve the efficiency of operations.  Conveyor systems transport inbound test kits from the receiving area to the laboratory and remove waste.  All automated testing equipment requiring purified water is linked directly to a centralized water-purification system.  Over 50,000 square feet of raised flooring allows laboratory instruments and PCs to be arranged or moved quickly and easily.  The security system includes proximity card readers to control access and a ceiling detector system to prevent foreign substances from being thrown into the laboratory.  In addition, three diesel generators and a UPS battery system are on-line in the event of electrical power shortage.  These back-up power sources allow specimen testing and data processing to continue until full power is restored, thus assuring LabOne's clients of continuous laboratory operation.

SBSI utilizes two facilities in Independence, Missouri under leases expiring in 2003.  Effective January 1, 2002, LabOne added a 50,000 square foot facility in Lee's Summit, Missouri under lease until 2011 to perform insurance applicant interviews and to process attending physician statements.  ExamOne has a five year lease expiring in 2004 for a facility used as office space in Voorhees, New Jersey and leases 28 locations across the United States as regional paramedical offices.  LabOne leases 11 locations in the Midwest which serve as LabOne Service Centers.  These facilities provide specimen collection services for patients and are typically located in medical office buildings.  Lab One Canada Inc. leases office space in Ontario Canada, which is used for sales and client services.  This lease expires in 2003.  Additionally, Lab One Canada Inc. leases space in Quebec Canada for assembly and distribution of specimen collection kits for Canadian insurance testing.  This lease expires in 2002.

ITEM 3. LITIGATION

In the normal course of business, LabOne had certain lawsuits pending at December 31, 2001.  During 2000 and 2001, LabOne became a co-defendant in several cases challenging toxicology results, including the processes and science underlying the determination of substituted or adulterated specimens submitted for toxicology testing.  In July 2001, the Company announced that a jury awarded $400,000 in compensatory damages to a flight attendant based upon the drug testing results reported by LabOne.  The Company believes that it has properly applied regulatory guidelines required for such testing and has appealed the verdict. The Company is insured for the loss and has reserved for any potential insurance deductibles related to these cases.

On March 5, 2002, a complaint was filed by a paramedical services company against LabOne and others.  The suit claims that LabOne interfered with the contractual rights of the paramedical services company with several of its affiliate examiners and wrongfully recruited employees to work for LabOne. The suit seeks injunctive relief and damages.  The resolution of this issue is not expected to be material to LabOne.

The Comptroller of the State of Texas conducted an audit of LabOne for sales and use tax compliance for the years 1991 through 1997 and contended that LabOne's insurance laboratory services are taxable under the Texas tax code.  The original assessment of $1.9 million was reduced to only include sales of services for applicants who were residents of Texas.  LabOne paid the revised assessment of $521,000 under protest in 2000 and is petitioning the Court for recovery of these amounts, including an additional $47,000 filed and paid in protest during 2001 for the period 1998 through August 1999.

Although LabOne cannot predict the outcome of such proceedings or any other claims made against it, management believes that the ultimate resolution of these claims will have no material adverse impact on the Company's financial position.

ITEM 5.  MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

The Registrant's common stock trades on The Nasdaq Stock Market® under the symbol LABS.  As of March 1, 2002, the outstanding shares were held by approximately 5,500 shareholders either directly or in street name.

The Company did not pay a dividend during 2001 or 2000.  The Board of Directors eliminated the quarterly dividend in 1999 to retain cash flow to finance the Company's debt obligations and growth plans.  Additionally, the Company's line of credit with Commerce Bank, N.A. currently prohibits the payment of dividends under the terms of the line of credit.  The Board of Directors will review the dividend policy on a periodic basis, but presently has no plans to pay a dividend in the near future.

The following are the high and low prices of LabOne's common stock for each quarter of 2001 and 2000:

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

2001 Compared to 2000

Revenue for the year ended December 31, 2001 was $233.9 million as compared to $169.2 million in 2000.  The increase of $64.7 million, or 38%, was due to increases in risk assessment revenue of $50.0 million, healthcare revenue of $11.3 million and SAT revenue of $3.4 million.  The risk assessment segment revenue increased from $109.3 million in 2000 to $159.3 million due primarily to increases of $28.1 million in paramedical testing and an increase of $16.8 million in insurance laboratory testing.  Insurance laboratory testing increased due to an increase in the base level of LabOne insurance applicants tested and due to $11.9 million of revenue from acquired Osborn clients effective September 2001.  Healthcare laboratory revenue increased from $35.3 million in 2000 to $46.6 million in 2001 due to a 23% increase in testing volumes and an increase in the average revenue per patient.  SAT revenue increased from $24.5 million in 2000 to $27.9 million in 2001 primarily due to a 11% increase in testing volumes.

Cost of sales increased $51.0 million, or 45%, for the year as compared to the prior year.  This increase is primarily due to increases in paramedical collections, payroll and material costs due to the growth of ExamOne and growth in the insurance and healthcare laboratory testing markets.  Insurance segment cost of sales expenses increased to $113.1 million as compared to $72.7 million during 2000 due to the growth of ExamOne and the acquisition of Osborn.  Healthcare cost of sales expenses were $29.6 million as compared to $23.6 million during 2000.  SAT cost of sales expenses were $22.6 million as compared to $18.0 million during 2000.  The increases in the healthcare and SAT segments are due primarily to increased testing volumes.

As a result of the above factors, gross profit increased $13.7 million, or 25%, from $54.9 million in 2000 to $68.6 million in 2001.  Insurance gross profit increased $9.6 million, or 26%, to $46.2 million in 2001.  Healthcare gross profit improved $5.3 million, from $11.7 million in 2000 to $17.0 million in 2001.  SAT gross profit decreased $1.2 million from $6.5 million last year to $5.3 million in 2001.

Selling, general and administrative (SGA) expenses increased $13.2 million, or 26%, in 2001 as compared to 2000 primarily due to increases in payroll and benefits and amortization expenses.  Payroll expenses increased $5.5 million or 23% for the year due to growth in the risk assessment, healthcare and corporate overhead divisions and the accrual of profit sharing bonuses in 2001.  Amortization expense increased $3.9 million due to non cash warrant expenses of $3.2 million related to the WCAS financing and $0.6 million related to warrants issued in exchange for an exclusive marketing arrangement.  Insurance overhead expenditures increased to $17.6 million as compared to $13.3 million in 2000 primarily due to the addition of Osborn and growth in ExamOne.  Healthcare overhead increased to $13.6 million as compared to $10.2 million in 2000 due to bad debt accruals and payroll expense.  SAT overhead increased from $4.0 million to $4.1 million in 2001.  Corporate overhead increased from $23.6 million in 2000 to $29.0 million due to the warrant amortization and payroll expenses.

Operating income increased 14% from $3.7 million in 2000 to $4.3 million in 2001.  The risk assessment segment had operating income of $28.7 million as compared to $23.4 million in 2000.  The healthcare segment operating income increased from $1.4 million in 2000 to $3.5 million in 2001.  The SAT segment operating income declined from $2.5 million in 2000 to $1.3 million in 2001.  Corporate operating expenses for the year increased from $23.6 million in 2000 to $29.1 million.

Non operating expense decreased $0.2 million in 2001 as compared to 2000, primarily due to lower interest expense.  Average income tax expense was 150% of pretax income in 2001 as compared to 138% in 2000.  The high average rate is due to amortization expense which is not deductible for tax purposes.

The combined effect of the above factors resulted in a net loss of $1.0 million, or $0.18 per share as compared to a net loss of $0.5 million, or $0.05 per share, in 2000.

2000 Compared to 1999

Revenue for the year ended December 31, 2000 was $169.2 million as compared to $119.7 million in 1999.  The increase of $49.5 million, or 41%, was due to increases in risk assessment revenue of $31.7 million, healthcare revenue of $10.5 million and SAT revenue of $7.3 million.  The risk assessment segment revenue increased from $77.7 million in 1999 to $109.3 million due primarily to increases of $25.9 million in paramedical testing and an increase of $5.5 million in SBSI revenue.  Insurance laboratory testing decreased 2% due to a 1% decrease in average revenue per applicant and a slight decrease in total applicants tested.  Healthcare laboratory revenue increased from $24.8 million in 1999 to $35.3 million in 2000 primarily due to a 46% increase in testing volumes.  SAT revenue increased from $17.2 million in 1999 to $24.5 million in 2000 primarily due to a 54% increase in testing volumes, partially offset by lower revenue per specimen.

Cost of sales increased $42.7 million, or 60%, for the year as compared to the prior year.  This increase is primarily due to increases in paramedical collections, payroll and the cost of motor vehicle and physician statements due to the acquisition and subsequent growth of ExamOne and growth in the healthcare and SAT markets.  Insurance segment cost of sales expenses increased to $72.7 million as compared to $41.9 million during 1999 due to the growth of ExamOne and SBSI.  Healthcare cost of sales expenses were $23.6 million as compared to $17.1 million during 1999.  SAT cost of sales expenses were $18.0 million as compared to $12.6 million during 1999.  The increases in the healthcare and SAT segments are due primarily to increased testing volumes.

As a result of the above factors, gross profit increased $6.8 million, or 14%, from $48.1 million in 1999 to $54.9 million in 2000.  Insurance gross profit increased $0.9 million, or 2%, to $36.7 million in 2000.  Healthcare gross profit improved $4.0 million, from $7.7 million in 1999 to $11.7 million in 2000.  SAT gross profit increased $1.9 million from $4.6 million last year to $6.5 million in 2000.

Selling, general and administrative (SGA) expenses increased $11.1 million, or 28%, in 2000 as compared to 1999 primarily due to increases in payroll and benefits, depreciation and amortization expenses.  Payroll expenses increased $5.6 million or 30% for the year due to a 33% increase in SGA employees related to growth in the healthcare and SAT divisions and the addition of

ExamOne.  Depreciation expense increased $1.3 million as compared to last year primarily related to information systems.  Amortization expense increased $1.0 million primarily due to a full year of the goodwill associated with the Lab Holdings merger and the ExamOne acquisition.  Insurance overhead expenditures, including allocated overhead, increased to $26.6 million as compared to $20.3 million in 1999 primarily due to the addition of ExamOne.  Healthcare overhead, including allocated overhead, was $14.5 million as compared to $12.2 million in 1999.  SAT overhead, including allocated overhead, increased from $5.4 million to $6.9 million.  These increases are due to the revenue growth in each segment.  The allocation of corporate overhead to the healthcare and SAT segments increased to $7.2 million for the year, as compared to $6.4 million in 1999.  Overhead allocated to the insurance segment was $13.3 million for the year.

Operating income decreased from $8.0 million in 1999 to $3.7 million in 2000.  The risk assessment segment, including overhead allocations, had operating income of $10.1 million as compared to $15.5 million in 1999.  The healthcare segment, including overhead allocations, experienced an operating loss of $2.8 million for 2000 as compared to an operating loss of $4.5 million in 1999.  The SAT segment, including overhead allocations, had an operating loss of $0.4 million in 2000 as compared to a loss of $0.8 million in 1999.  Unallocated operating expenses for the year were $3.2 million related to amortization and corporate expenses.  Unallocated operating expenses in 1999 were $2.2 million primarily due to merger expenses, partially offset by gains on the sale of the former laboratory and administrative facilities.

In the fourth quarter 2000, operating income was reduced $2.1 million due to the Company increasing its allowance for doubtful accounts and recognizing other additional expenses.  During the quarter, one of the largest SAT clients became delinquent on its trade payments, resulting in theCompany reaching an agreement to exchange the trade receivable for a short-term note receivable.  As part of the agreement, the balance due from the client was reduced by $0.2 million.  The Company increased its allowance for doubtful accounts by $0.8 million, due to the specific SAT client and an additional allowance for healthcare receivables.  Other additional expenses include $0.7 million in one-time payroll charges, due primarily to severance expense and certain employees' bonus arrangements entered into and in connection with the expansion of ExamOne and SAT.

Non operating expense increased $1.3 million in 2000 as compared to 1999, primarily due to increased interest expense on the line of credit borrowings.  Average income tax expense was 138% of pretax income in 2000 as compared to 48% in 1999.  The increase is due to the combination of lower pretax earnings and full-year merger amortization expense which is not deductible for tax purposes.

The combined effect of the above factors resulted in a net loss of $0.5 million, or $0.05 per share as compared to net earnings of $2.9 million, or $0.27 per share, in 1999.

TRENDS

The following is management's analysis of certain existing trends that have been identified as potentially affecting the future financial results of the Company.  Due to the potential for a rapid rate of change in any number of factors associated with the risk assessment and clinical industries, it is difficult to quantify with any degree of certainty LabOne's future volumes, sales, margins or net earnings.

Amortization expense in 2001, comprised of $4.3 million for goodwill and customer list and $3.8 million for the amortization of the WCAS and other warrants issued, was $8.1 million.  Amortization expense in 2000 was $4.3 million primarily for goodwill.  Effective 2002, the Company will no longer amortize goodwill. (See Recent Accounting Developments.) The majority of the historical amortization expense was not deductible for tax purposes and had the effect of increasing the effective income tax rate.

Effective August 31, 2001, LabOne purchased Osborn, a provider of laboratory testing and other risk assessment services to the life insurance industry.  With this acquisition, LabOne will have a combined revenue base of $250 million and will annually perform laboratory testing for approximately 10 million individuals for its risk assessment, healthcare and substance abuse testing clients.  Due to the reduction of operational overlap, LabOne expects to generate up to $10 million of annual cost savings from the acquisition.

The risk assessment services market continues to be highly competitive. The primary focus of the competition has been on the ability to deliver integrated services such as total account management and electronic connectivity.  LabOne continues to maintain its market leadership by a commitment to customer service, by providing quality products and services at competitive prices and by continuing to develop innovative data management services and technological solutions that differentiate us from competitors.

During 2001, LabOne continued to contract with national insurance carriers to provide teleunderwriting services.  Under the terms of these contracts, LabOne personnel conduct telephone interviews relating to the medical histories of new life insurance policy applicants.  It is anticipated that there will be a substantial increase in these services provided during 2002.

Revenue from the ExamOne division increased $28.1 million in 2001.  The paramedical industry historically returns a lower gross margin than LabOne's other market segments.  In most cases, a substantial percentage of the revenue from a specimen collection is paid to a contractor who owns and operates an independent local office which arranges for the collection.  As the revenue from ExamOne continues to grow as a percentage of total LabOne revenue, its lower gross margins will add to the total profitability of LabOne but will reduce the average gross profit margin percentage.

In the healthcare division, the Company continued its trend of growth through the Lab Card® Program, aggressively marketing to physicians and new managed care agreements.  The Lab Card Program now has more than 3 million members.  The program continued to expand through new members as well as increased participation from existing members.

In the physician marketing and managed care area, the healthcare division continues to service approximately 750,000 members under our exclusive managed care outpatient laboratory service contracts.  The Company continues to add network approvals for healthcare plans in focused regional physician markets to increase penetration.  Managed care organizations, and the physicians who are under their contracts, continue to choose LabOne for its high-quality testing, disease management data capabilities, and responsive customer service and support.

The SAT market segment is more cyclical in nature and sensitive to economic conditions, and levels of employment and labor hiring than LabOne's other market segments.  Due to the recent economic downturn, revenue growth in this segment has diminished.  If economic activity and levels of employment and labor hiring do not improve, revenues in this segment may continue to lag expectations.

In addition to its urine drug testing, LabOne markets oral fluid drug testing services with a laboratory-based test that identifies commonly used illicit drugs in oral fluid samples.  The oral fluid collection avoids the process of collecting and handling of urine samples and the collection with the oral fluid device is directly observable.  LabOne markets this service to employers and third party administrators nationwide.

There is a general bad debt risk exposure in the SAT and healthcare divisions.  The Company has estimated the exposure based on historical information and expected collection rates, and has reserved an appropriate allowance for doubtful accounts.

The Company's facility was financed through the City of Lenexa, Kansas, with industrial revenue bonds.  In conjunction with the bonds, LabOne received income tax credits through the State of Kansas High Performance Incentive Plan to be applied against state income taxes for up to 10 years, or until the credit is completely used.  The amount of the credit exceeds $4 million.

In conjunction with the purchase of Osborn, WCAS was issued $35.0 million of convertible preferred stock and $15.0 million of subordinated debt.  The preferred stock can be converted into LabOne common stock at a rate of $8.32 per share and earns a paid-in-kind dividend of 8% which is compounded semiannually.  In the calculation of earnings per share, the preferred dividend is deducted from net earnings in arriving at earnings available to common shareholders and reduces basic earnings per share.  In calculating diluted earnings per share, the dividend is not deducted, but the number of shares outstanding is adjusted by the potential conversion of the preferred stock into common stock and will reduce the calculated earnings per share.  The $15.0 million of subordinated debt has a cash coupon of 11%.

LIQUIDITY AND CAPITAL RESOURCES

LabOne's working capital position increased from $24.6 million at December 31, 2000, to $30.6 million at December 31, 2001.  This increase is due to cash provided by net financing activities and cash provided by operations exceeding the acquisition costs of Osborn and capital additions.  Net cash provided by operations increased from $4.4 million in 2000 to $14.2 million in 2001.  Non-cash expenses included in net earnings, primarily amortization and depreciation, increased $7.2 million as compared to 2000.  The net change in non-cash working capital items decreased as compared to last year.  Accounts receivable grew from $33.9 million as of December 31, 2000 to $42.1 million as of December 31, 2001, due to the increase in revenue.  The allowance for doubtful accounts declined from $4.4 million in 2000 to $3.6 million due to implementing new third party collection procedures, which resulted in writing off old accounts receivable that were fully reserved in prior periods.  Total cash and investments at December 31, 2000, were $5.9 million, as compared to $1.6 million at December 31, 2000.  Management expects to be able to fund operations from a combination of cash flow from operations and borrowings.

To finance the purchase of Osborn, LabOne issued $35 million of convertible preferred stock and $15 million of subordinated debt to WCAS in exchange for $50 million cash.  The preferred stock is convertible into LabOne common stock at a rate of $8.32 per share and earns a paid-in-kind dividend at a fixed rate of 8% compounded semiannually.  The convertible preferred stock may be converted at the Company's election after the third anniversary of issuance if the common stock is trading at or above $16.64 per share for 30 out of 45 consecutive trading days.  Final redemption of the convertible preferred stock on the seventh anniversary of issuance may be paid in cash or stock at the Company's election.  The subordinated debt bears a fixed interest rate of 11% and matures 25% on each of the fifth and sixth anniversaries of issuance and the remaining 50% on the seventh anniversary of issuance.

During 2001, the Company spent $61.8 million for capital investments, as compared to $9.0 million in 2000 and $12.8 million in 1999.  The amount spent in 2001 included $50.6 million for the purchase of Osborn and $2.4 million on the acquisition of various paramedical operations.  Additionally, $6.3 million was spent for software development and information systems.  Capital expenditures for 2000 were primarily related to expansion of all three business segments, including $3.9 million for information systems improvements and $2.0 million in additional laboratory equipment.  Of the amount spent in 1999, $5.2 million was spent on completion of the Company's new facility and $2.1 million was spent on the purchase of ExamOne.  Future capital asset expenditures, excluding strategic expansions, are expected to be approximately $9 million annually.

Interest on the industrial revenue bonds issued to finance the construction of the Company's facility is based on a taxable seven-day variable rate which, including letter of credit and remarketing fees, is approximately 3.1% as of March 1, 2002.  The bonds mature over the next eight years in increments of $1.85 million per year plus interest.  The third principal payment of $1.85 million was paid in September 2001.  Interest on the Company's line of credit is currently based on the 30-day LIBOR rate plus 225 basis points and including bank fees is approximately 4.1% as of March 1, 2002.

During the first quarter 2000, the Board of Directors approved a stock repurchase program pursuant to which LabOne is authorized to repurchase up to $10 million of its common stock.  During 2000, the Company repurchased 841,000 shares at a cost of approximately $5.9 million. The Company currently does not intend to make additional share repurchases.

The Company increased its available line of credit from $15 million to $25 million to accommodate stock repurchases in 2000.  During 2001, the Company increased the line of credit to $35 million.  The Company is currently in discussions with several banks for a new three year facility that would increase this line of credit in 2002.

ITEM 7(a). QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

A foreign currency risk exposure exists due to billing Canadian subsidiary revenue in Canadian dollars and the direct laboratory expenses associated with this revenue being incurred in US dollars.  This exposure is not considered to be material.  Any future material Canadian currency fluctuations against the US$ could result in a decision to hedge future foreign currency cash flows, or to increase Canadian prices.

An interest rate risk exposure exists due to LabOne's liability of $14.5 million in industrial revenue bonds and $28 million borrowing on its line of credit.  The interest expense incurred on the bonds is based on a taxable seven-day variable rate, which including letter of credit and remarketing fees, is approximately 3.1% as of March 1, 2002.  The interest expense on the line of credit is based on the 30-day LIBOR rate plus 2.25% and is currently approximately 4.1%.  An assumed 10% increase in interest rates (representing approximately 40 basis points) would potentially increase interest expense on these instruments by $0.2 million annually.

Recent Accounting Developments

In June 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 141 "Business Combinations" (SFAS 141) and Statement of Financial Accounting Standards No. 142 "Goodwill and Other Intangible Assets" (SFAS 142).  SFAS 141 requires that the purchase method of accounting be used for all business combinations initiated after June 30, 2001.  It also specifies the types of acquired intangible assets that require recognition and reporting separately from goodwill.  SFAS 142 requires that goodwill and intangible assets with indefinite useful lives no longer will be amortized, but instead tested for impairment at least annually in accordance with the provisions in the statement.  SFAS 142 also requires that intangible assets with estimable useful lives be amortized over their respective estimated useful lives to their residual values and reviewed for impairment.

The Company has adopted the provisions of SFAS 141 upon its issuance and SFAS 142 effective July 1, 2001.  Because the Osborn acquisition occurred after July 1, 2001, the Company did not amortize any of the goodwill generated in the purchase.  As of January 1, 2002, the Company will no longer amortize any goodwill, and in accordance with SFAS 142, has performed an evaluation of its goodwill that was acquired in prior business combinations to identify intangible assets that require recognition and reporting apart from goodwill.  The Company has concluded that the customer list acquired from the purchase of GIB Laboratories is not goodwill and will recognize the final amortization of this customer list in January 2002.  Also, on January 1, 2002, in accordance with SFAS 142, the Company performed a goodwill impairment assessment and concluded that no impairment of goodwill exists at such date.

The Company had unamortized goodwill in the amount of $81.7 million at December 31, 2001.  Amortization expense related to goodwill was $3.5 million and $3.4 million for the years ended December 31, 2001 and 2000, respectively.

Critical Accounting Policies

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

While many operational aspects are subject to complex federal, state and local regulations, the accounting for LabOne's business is generally straightforward with revenues primarily recognized upon completion of the testing process or delivery of services provided to the client.

The estimate of reserves for doubtful accounts involves a monthly standardized approach to review the collectibility of receivables based on the aging of accounts receivable. Historical collection and payor reimbursement experience is an integral part of the estimation process related to reserves for doubtful accounts. In addition, the current state of billing functions is assessed in order to identify any known collection or reimbursement issues in order to assess the impact, if any, on reserve estimates, which involve judgment.  Revisions in reserve estimates are recorded as an adjustment to bad debt expense within selling, general and administrative expenses.  The collection and reserves processes, along with the monitoring of billing processes, helps to reduce the risk associated with material revisions to reserve estimates resulting from adverse changes in collection and reimbursement experience and billing functions.

Certain internal and external costs incurred in connection with developing or obtaining software for internal use are capitalized in accordance with the American Institute of Certified Public Accountants' Statement of Position 98-1, Accounting for the Costs of Computer Software Developed or Obtained for Internal Use. These capitalized costs are included in property and equipment on the consolidated balance sheets and are subject to amortization, over the estimated useful life of the software, beginning when the software project is complete.

Independent Auditors' Report

The Board of Directors
LabOne, Inc.:

We have audited the accompanying consolidated balance sheets of LabOne, Inc. and subsidiaries as of December 31, 2001 and 2000, and the related consolidated statements of operations, stockholders' equity, and cash flows for each of the years in the three-year period ended December 31, 2001. In connection with our audits of the consolidated financial statements, we have also audited the financial statement schedule. These consolidated financial statements and financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements and financial statement schedule based on our audits.

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

As discussed in note 1 to the consolidated financial statements, effective July 1, 2001, LabOne, Inc. and subsidiaries adopted the provisions of Statement of Financial Accounting Standards (SFAS) 141, Business Combinations, and certain provisions of SFAS 142, Goodwill and Other Intangible Assets, as required for goodwill and intangible assets resulting from business combinations consummated after June 30, 2001.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of LabOne, Inc. and subsidiaries as of December 31, 2001 and 2000, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2001, in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

(and its wholly owned subsidiary, ExamOne World Wide of NJ, Inc.); and Osborn Group, Inc. (and its wholly owned subsidiaries, Applied BioConcepts, Inc. and Intellisys, Inc.). All significant intercompany transactions have been eliminated in consolidation. Certain amounts in the prior year consolidated financial statements have been reclassified for consistent presentation.

Cash and Cash Equivalents

Cash and cash equivalents include demand deposits in banks, marketable securities with original maturities of three months or less, money market investments, and overnight investments that are stated at cost, which approximates market value.

Inventories

Inventories consist of completed specimen collection kits, laboratory supplies, and various materials used in the assembly of specimen collection kits for sale to clients. Inventory is valued at the lower of cost (first-in, first-out) or market.

Property, Plant, and Equipment

Property, plant, and equipment additions are recorded at cost, which includes interest capitalized during construction when material. Facilities leased pursuant to revenue bond financing transactions are accounted for as purchases, with the cost of the leased property included in property, plant, and equipment and the related obligation included in long-term debt.

Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets as follows:

|Buildings                 | 30 years   
|------------------------- | -----------
|Laboratory equipment      | 3 - 5 years
|Data processing equipment | 3 - 5 years
|Office equipment          | 5 years    

Software Developed for Internal Use

Certain internal and external costs incurred in connection with developing or obtaining software for internal use are capitalized in accordance with the American Institute of Certified Public Accountants' Statement of Position 98-1, Accounting for the Costs of Computer Software Developed or Obtained for Internal Use. These capitalized costs are included in property and equipment on the consolidated balance sheets and are subject to amortization over the estimated useful life of the software, beginning when the software project is complete.

Cost of Borrowings

Expenses directly related to the issuance of debt are deferred and amortized over the period the debt is expected to be outstanding using the interest method.

Intangible Assets

Intangible assets are recorded at their acquisition cost, net of amortization. The excess of cost over fair value of net assets acquired for acquisitions prior to July 1, 2001 is being amortized on a straight-line basis over periods of fifteen to twenty years. The Company assesses the recoverability of this intangible asset by determining whether the amortization of the goodwill balance over its remaining life can be recovered through undiscounted future operating cash flows of the acquired operation. When impairment is indicated, any impairment loss is measured by the excess of carrying values over fair values

Effective July 1, 2001, the Company adopted the provisions of Statement of Financial Accounting Standards (SFAS) 141, Business Combinations, and certain provisions of SFAS 142, Goodwill and Other Intangible Assets, as required for goodwill and intangible assets resulting from business combinations consummated after June 30, 2001.

Impairment of Long-Lived Assets

When facts and circumstances indicate potential impairment, LabOne evaluates the recoverability of carrying values of long-lived assets, including intangibles, using estimates of undiscounted future cash flows over remaining asset lives. When impairment is indicated, any impairment loss is measured by the excess of carrying values over fair values. During the fourth quarter of 1997, LabOne decided to dispose of its office and headquarters building and lab facility, which, net of accumulated depreciation, was classified as real estate available-for-sale at December 31, 1998. An impairment loss of $6,553,279 related to the anticipated sale was recorded in 1997, which reduced the carrying value to $3,515,000. In 1999, the Company sold all real estate available-for-sale for $4,379,340 and recognized a gain of $864,340.

Use of Estimates in the Preparation of Consolidated Financial Statements

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

Fair Value of Financial Instruments

Estimates of fair values are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could affect the estimates. The fair market value of LabOne's financial instruments at December 31, 2001 and 2000 approximates their carrying values.

Concentration of Business Risk

LabOne provides laboratory testing, investigative services, and paramedical examinations (all comprising the "risk assessment" segment) for insurance companies. LabOne also provides healthcare and substance abuse testing largely to noninsurance customers. For the year ended December 31, 2001, one insurance customer comprised more than 10% of total revenues for the year. LabOne has a contract with this customer for a ten-year period ending in 2010 that the customer may terminate if LabOne encounters service level failures that materially impact the services provided.

Income Taxes

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

Earnings Per Share

Basic earnings per share are computed using the net earnings available to common shareholders divided by the weighted average number of common shares outstanding and contingently issuable shares. Diluted earnings per share for the year ended December 31, 1999 was computed using the weighted average number of common shares and dilutive stock options. Beginning September 30, 2001 and thereafter, for periods with net earnings, diluted earnings per share are computed using the weighted average number of common shares, dilutive stock options, and preferred convertible stock. For periods in which net losses are incurred, basic and diluted shares are the same.

The following table reconciles the weighted average common shares used in the basic earnings per share calculation, and the weighted average common shares and common share equivalents used in the diluted per share calculation:

|                                                                     | 2001       | 2000       | 1999

Recently Issued Accounting Standards

In June 2001, the Financial Accounting Standards Board issued SFAS 141, Business Combinations, and SFAS 142, Goodwill and Other Intangible Assets. SFAS 141 requires that the purchase method of accounting be used for all business combinations after June 30, 2001. SFAS 141 specifies criteria that intangible assets acquired in a business combination must meet to be recognized and reported separately from goodwill. SFAS 142 requires that goodwill and intangible assets with indefinite useful lives no longer be amortized, but instead tested for impairment at least annually in accordance with the provisions of SFAS 142. The standard also requires that intangible assets with estimable useful lives be amortized over their respective estimated useful lives to their estimated residual values, and reviewed for impairment in accordance with SFAS 121, Accounting for the Impairment of Long-Lived Assets to Be Disposed Of, and subsequently by SFAS 144 after its adoption in 2002.

The Company has adopted the provisions of SFAS 141 upon its issuance and SFAS 142 effective July 1, 2001. Because the Osborn Group, Inc. acquisition occurred after June 30, 2001, the Company did not amortize any of the goodwill generated in the purchase. As of January 1, 2002, the Company will no longer amortize any goodwill, and in accordance with SFAS 142, has performed an evaluation of its goodwill that was acquired in prior business combinations to identify intangible assets that require recognition and reporting separately from goodwill. The Company has concluded that the customer list acquired from the purchase of GIB Laboratories is not goodwill and will recognize the final amortization of this customer list in January 2002. Also, on January 1, 2002, in accordance with SFAS 142, the Company performed a goodwill impairment assessment and concluded that no impairment of goodwill exists at such date.

As of the date of adoption of SFAS 142, the Company has unamortized goodwill of approximately $81,728,000 and unamortized identifiable intangible assets of approximately $203,000, all of which will be subject to the transition provisions of SFAS 142. If LabOne's acquisitions occurring after June 30, 2001 (see note 2) had been amortized, total amortization expense would have been approximately $4,600,000 for the year ended December 31, 2001. As a result of the adoption of SFAS 142, it is anticipated that amortization expense related to goodwill will be approximately $7,019,000 lower for 2002 than that which would have been recognized under prior accounting rules. This amount includes approximately $3,300,000 of goodwill amortization that would have been expensed for the Osborn Group, Inc. acquisition.  Amortization expense related to goodwill was $3,464,121, $3,427,386, and $2,400,027 for the years ended December 31, 2001, 2000, and 1999, respectively.

(2) Merger, Acquisitions, and Intangible Assets

As discussed in note 1, LabOne adopted the provisions of SFAS 141 and SFAS 142. During 2001, LabOne acquired several paramedical service companies both before and after June 30, 2001. Goodwill related to acquisitions finalized prior to June 30, 2001 was amortized over a period of fifteen years through December 31, 2001. Goodwill related to acquisitions finalized after June 30, 2001 is being amortized in accordance with SFAS 141 and SFAS 142 such that there is no amortization expense on this goodwill.

Acquisitions

The following table summarizes the estimated fair value of the assets acquired and liabilities assumed at the date of acquisition.

Prior to June 30, 2001, LabOne acquired four paramedical service companies located in Seattle, Washington, Anchorage, Alaska, Salt Lake City, Utah, and Durham, North Carolina. The results of the businesses' operations have been included in the consolidated financial statements since the dates of acquisition. The acquired businesses provide paramedical examinations that are used to assist an insurance company in objectively evaluating the mortality and morbidity risks posed by policy applicants. Total consideration paid for the acquisitions consisted of cash payments of $1,777,169 and the issuance of two notes payable totaling $78,000. The acquired intangible assets of the $233,500 consist of noncompete agreements with the former owners and have a weighted average useful life of approximately five years. The excess of the aggregate purchase price over the fair market value of net assets acquired of approximately $1,564,000 was being amortized over a period of fifteen years.



Pursuant to a Stock Purchase Agreement dated August 31, 2001, LabOne purchased all of the outstanding capital stock of Osborn Group, Inc. (Osborn), a leading provider of laboratory testing and other risk assessment services to the life insurance industry. Intellisys, Inc, Applied BioConcepts, Inc., and Osborn Laboratories (Canada), Inc. were wholly owned subsidiaries of Osborn and were included in the purchase. The results of the businesses' operations have been included in the consolidated financial statements since that date. The purchase price was $49,000,000 and transaction costs paid to third parties were $1,552,000. As a result of the transaction, Osborn became a wholly owned subsidiary of LabOne. Due to operational overlap, LabOne expects to reduce costs through economies of scale. As Osborn was acquired after June 30, 2001, the excess of the aggregate purchase price over the fair market value of net assets acquired of approximately $49,862,000 is not being amortized. To fund the acquisition and the related expenses of the Osborn transaction, Welsh, Carson, Anderson & Stowe (WCAS) invested a total of $50,000,000 in preferred stock and subordinated debt in LabOne pursuant to a Securities Purchase Agreement dated August 31, 2001. LabOne issued $35,000,000 of convertible preferred stock and $15,000,000 of subordinated debt to WCAS in exchange for $50,000,000 in cash. The preferred stock is convertible into LabOne common stock at a rate of $8.32 per common share, and earns a paid-in-kind dividend at a fixed rate of 8% compounded semiannually. The subordinated debt bears a fixed interest rate of 11% and matures on the seventh anniversary of issuance.

The $35,000,000 of preferred stock consisted of two distinct series of stock in the original issuance: 14,000 shares of Series B-1 convertible preferred stock, par value of $1,000 per share, accruing paid-in-kind dividends at 8%; and 21,000 shares of Series B-2 preferred stock, par value $1,000, accruing paid-in-kind dividends at 18%. Upon shareholder approval, which occurred on January 31, 2002, the Series B-2 preferred stock was retroactively converted into Series B-1 convertible preferred stock with paid-in-kind dividends accreting at the Series B-1 rate of 8% beginning September 1, 2001.

The 35,000 shares of Series B-1 convertible preferred stock, plus accreted paid-in-kind dividends, is convertible into the Company's common stock at any time up to seven years after issuance at the rate of $8.32 per common share. If all of the issued Series B-1 shares were converted as of December 31, 2001, the number of common shares issued would be 4,206,730. If the accreted value of the preferred stock paid-in-kind dividends were converted into common stock as of December 31, 2001, the number of shares issued would be 112,179.

Following the third anniversary of issuance, LabOne can convert the preferred stock if LabOne's common stock price reaches $16.64. The number of shares issued upon such conversion would be based on the accreted value of the Series B-1 preferred stock divided by the $8.32 conversion price. If, after seven years, the holders, or LabOne, has not converted the Series B-1 convertible preferred stock, the holder can exercise the put/call option that would require the Company to purchase the Series B-1 preferred shares plus any accreted paid-in-kind dividends. The put/call feature allows LabOne to determine settlement either in cash or common stock. If the method of settlement selected is stock, the shares to be issued are dependent on the market price of the common stock at the exercise date of the put as compared to the conversion price of $8.32. If the market price exceeds the conversion price, then the shares to be issued are the accrued value of the preferred stock, divided by the market price of the stock. If the market price is less than the conversion price of $8.32, then the accrued value of the preferred stock is divided by 0.95 to arrive at the value.



In addition to the issuance of B-1 convertible preferred stock on August 31, 2001, LabOne issued 350,000 warrants with a strike price of $0.01 to the holders of the Series B-1 convertible preferred stock. The warrants were exercisable immediately. The market price at the date of grant was $9.25, resulting in an intrinsic value of $9.24 per warrant. Upon issuance, LabOne recorded a noncash warrant amortization expense of $3,234,000.

As a result of the issuance of B-1 convertible preferred stock, LabOne calculated the beneficial conversion feature related to the transactions. The issuance of the 14,000 shares of B-1 preferred stock on August 31, 2001 resulted in a beneficial conversion feature of $0.93 per share. The beneficial conversion feature per share equals the market price of LabOne stock at the date of issuance, August 31, 2001, less the conversion rate of $8.32 per share. The total intrinsic value of the conversion feature is equal to the 1,682,692 shares multiplied by the intrinsic value per share of $0.93 for a total amount of approximately $1,565,000. Due to shareholder approval on January 31, 2002, the retroactive conversion of the 21,000 shares of B-2 stock into B-1 stock resulted in a beneficial conversion value of $7.68 per share. This beneficial conversion value is equal to the difference between the market price of LabOne stock of $16.00 at the January 31, 2002 conversion date, less the conversion rate of $8.32 per share. The total intrinsic value of the former B-2 stock conversion feature is equal to the 2,524,038 common shares into which the B-2 could be converted multiplied by the intrinsic value per share of $7.68 for a beneficial conversion value of approximately $19,385,000. In each case, the intrinsic value of the conversion feature was charged to retained earnings, with a corresponding increase in paid-in capital.

After June 30, 2001, LabOne acquired two paramedical service companies located in Virginia Beach, Virginia and in Cranston, Rhode Island. The results of the businesses' operations have been included in the consolidated financial statements since the dates of acquisition. The acquired businesses provide paramedical examinations that are used to assist an insurance company in objectively evaluating the mortality and morbidity risks posed by policy applicants. Consideration for the acquisitions consisted of cash payments of $650,000, the issuance of a $135,000 note payable, which was subsequently paid on November 27, 2001, and the forgiveness of accounts receivable owed by a former owner to LabOne of $19,418. The $40,000 acquired intangible asset is a noncompete agreement with a former owner and has a useful life of three years. As the businesses were acquired after June 30, 2001, the excess of the aggregate purchase price over the fair market value of net assets acquired of $744,000 is not being amortized.

On November 5, 1999, LabOne acquired a paramedical services company and a paramedical billing service provider. The paramedical services company was acquired for $279,000 and cash installments of $40,000 each year beginning in 2000 for five years and 10% of gross revenue for the next six years. The minimum payments under the gross revenue agreement provision are estimated to be $240,000. The current portion of the cash installments and the gross revenue percentage payments is recorded in other current liabilities with the remainder of the minimum purchase price recorded as a long-term payable. The excess of the aggregate minimum purchase price over the fair market value of net assets acquired of approximately $469,000 was being amortized over a fifteen-year period.

The paramedical billing service provider was acquired for $1,912,000 in cash and the issuance of 250,000 warrants. In the warrant agreement, the warrants would vest if specified revenue targets were achieved. As of December 31, 2001, all of the issued warrants were exercisable. The excess of the aggregate purchase price over the fair market value of net assets acquired of approximately $1,731,000 was being amortized over a fifteen-year period.



During 2001, the goodwill associated with the paramedical billing service provider decreased $1,000,000 due to a lapse of a guarantee of the value of warrants issued to the former owner of the acquired paramedical billing service provider. According to the agreement, if the Company's stock price exceeded specified levels during the period in which the warrants issued in the acquisition were exercisable, the accrued guarantee would lapse.

On August 10, 1999, upon the approval of the required number of shareholders of both companies, LabOne, Inc. was merged into Lab Holdings, Inc., its parent. The combined company's name was then changed to LabOne, Inc. The merger provisions included a 3-for-2 stock split for all Lab Holdings shares. LabOne shares that did not elect the cash option were exchanged for combined company shares on a 
1-for-1 basis. The Company paid $12.75 per share or $10,264,000 in cash for 805,000 shares of LabOne common stock. The Company paid $2,318,000 in related transaction costs. The transaction was accounted for as the acquisition of minority interest under the purchase method, resulting in goodwill of approximately $24,124,000. This goodwill was being amortized over a twenty-year period.

All of the above acquisitions have been accounted for under the purchase method and, accordingly, the operating results of the acquired companies have been included in the consolidated statements of operations from the dates of acquisition. Contingent consideration will be recorded when earned and will increase goodwill. The following unaudited pro forma consolidated results of operations of the Company for the years ended December 31, 2001, 2000, and 1999 assumes the acquisitions occurred as of the beginning of the periods presented:

On December 17, 2001, the Company increased its line of credit from $25,000,000 to $35,000,000. The additional $10,000,000 is to be used to finance daily operations. The line of credit bears variable interest, which at December 31, 2001 was approximately 4.12%. The principal of the line of credit is due on March 31, 2002. Under the terms of the agreement, the Company agrees not to merge or consolidate with another entity, not to pay dividends or make any other payments to shareholders, and to maintain a certain tangible net worth and certain other financial ratios.

During the first quarter of 2002, the Company began negotiations with several banks for a new three-year revolving credit facility. As of the date of this report, the Company has received commitment letters for a revolving credit facility that allows for the extension of the due date of the currently outstanding line of credit sufficient to classify this debt as long-term. The Company expects to conclude discussions with these banks in the second quarter of 2002.

In conjunction with building its new facility, LabOne has received the Kansas High Performance Incentive Program (HPIP) tax credit. LabOne was certified by the State of Kansas, and received a credit to offset all of its 1999, 2000, and 2001 Kansas income tax liability related to operations of the new facility. Any unused portion of the credit can be carried forward for a period of ten years, provided LabOne continues to meet requirements of the program. HPIP credits qualified in 1999 and 2000 for potential use in 1999 and subsequent years were approximately $6,749,000. LabOne used HPIP credits of approximately $110,000 and $71,000 in 2001 and 2000, respectively. A valuation allowance has been provided because the Company must prove it has the requisite employee wage scale and other specified items before it may use the qualified credits already earned.

LabOne had certain capital loss carryovers that were attributes of the former Lab Holdings. These loss deductions gave rise to deferred tax assets, however, a valuation allowance had been provided because full realization of the deferred tax assets was not expected. However, LabOne was able to use all of the federal net operating loss deduction in 2000. The usage of this net operating loss reduced income taxes by approximately $543,000.

(5) Benefit Plans

LabOne maintains a money purchase pension plan for all employees who have completed one-half year of service and have attained age twenty and one-half years. The plan is a defined contribution plan under which LabOne contributes a percentage of a participant's annual compensation. LabOne's contributions net of forfeitures to the plan were $2,768,000, $2,351,000, and $2,056,000 for the years ended December 31, 2001, 2000, and 1999, respectively.

LabOne has a profit sharing (401(k)) plan for all employees who have completed six months of service and a minimum of five hundred hours of service and have attained the age of twenty and one-half years. LabOne contributes on behalf of each participant an amount equal to 50% of the participant's annual contributions, but not in excess of 5% of the participant's annual compensation. LabOne's contributions are invested in LabOne common stock. LabOne's contributions to the plan net of forfeitures for the years ended December 31, 2001, 2000, and 1999 were $1,085,000, $913,000, and $830,000, respectively.

(6) Stock Options and Warrants

LabOne has a long-term incentive plan, which provides for granting awards, including stock options, for not more than 3,137,012 shares of LabOne common stock. LabOne has granted certain stock options which entitle the grantee to purchase shares for a price equal to the fair market value at date of grant with option periods up to ten years.

The Company accounts for stock options in accordance with the provisions of Accounting Principles Board (APB) Opinion 25, Accounting for Stock Issued to Employees, and related interpretations. As such, compensation expense is recorded on the date of grant only if the current market price of the underlying stock exceeds the exercise price. The Company has adopted SFAS 123, Accounting for Stock-Based Compensation, which allows entities to continue to apply the provisions of APB 25 and provide pro forma net earnings and pro forma earnings per share disclosures for employee stock option grants as if the fair value-based method defined in SFAS 123 had been applied. The Company has elected to continue to apply the provisions of APB 25 and provide the pro forma disclosure provisions of SFAS 123.

In connection with the merger transaction, stock options held by pre-merger LabOne employees were converted on a 1-for-1 basis to options on the Company's common shares. All eligible Company employees are now covered by this plan. On January 31, 2002, the Company's shareholders approved the conversion of the B-2 preferred stock into B-1 convertible preferred stock. This resulted in a change in control event under the plan, thereby immediately vesting all outstanding options as of that date. A summary of the status of this stock option plan as of December 31, 2001, 2000, and 1999 and changes during the years then ended is presented below:

The weighted average per share fair value of stock options granted during 2001, 2000, and 1999 was $4.65, $3.65, and $2.46, respectively, on the date of grant using the Black Scholes option-pricing model with the following weighted average assumptions:

|                           | 2001  | 2000 | 1999
|-------------------------- | ----- | ---- | ----
|Expected dividend yield    | %    |     | 7.0 
|Risk-free interest rate    | 5.1%  | 6.6  | 5.8 
|Expected volatility factor | 55.0% | 46.4 | 43.0
|Expected life (years)      | 6     | 6    | 6   

Since the Company applies APB 25 in accounting for its plans, no compensation cost has been recognized for its stock options in the consolidated financial statements. Had the Company recorded compensation cost based on the fair value of options at the grant date, the Company's net earnings and earnings (loss) per share would have been reduced by approximately $535,000 or $0.05 per share in 2001, $659,000 or $0.06 per share in 2000, and $633,000 or $0.06 per share in 1999.

Pro forma net earnings reflect only options granted in 2001, 2000, and 1999. Therefore, the full impact of calculating compensation cost for stock options under SFAS 123 is not reflected in the pro forma net earnings amounts presented above because compensation costs are reflected over the options' vesting periods. Compensation cost for prior option grants is not considered.

On August 31, 2001, LabOne issued 350,000 warrants with a strike price of $0.01 to the holders of the B-1 preferred stockholders. The warrants are exercisable immediately. The market price at the date of the grant was $9.25, resulting in an intrinsic value of $9.24 per warrant. LabOne recorded $3,234,000 in related warrant expense during the year.

In 1999, LabOne issued 50,000 warrants in conjunction with a distribution agreement. These warrants were exercised in 2001, resulting in an after-tax charge of $456,000.

At December 31, 1998, the directors of Lab Holdings had 60,000 stock options at a weighted average price of $26.50 per share, of which 20,000 were exercisable. As a result of the merger, the exercisable options were adjusted to reflect the 3-for-2 stock split. The resulting 30,000 exercisable LabOne stock options have an exercise price of $17.66 per share.

LabOne entered into marketing agreements with three companies during 1998 and 1999. In conjunction with these agreements, LabOne granted warrants for the purchase of 1,500,000 shares of common stock at an exercise price equal to the fair value of the stock at the grant date (500,000 shares at $17.00, 500,000 shares at $15.44, and 500,000 shares at $12.375). During the first quarter of 1999, the marketing agreement with shares valued at $17.00 was terminated. The remaining warrants may become exercisable each quarter for five years provided certain conditions are met, including achievement of specified levels of revenues. The specified levels of revenue resulting from these agreements have not been met; thus, none of the warrants were exercisable as of December 31, 2001.

(7) Business Segment Information

The Company operates principally in three lines of business: insurance, health care, and substance abuse testing. The insurance line of business provides risk-appraisal laboratory testing, paramedical physical evaluations, and information services to the insurance industry. The testing and physical evaluations performed and information provided by the Company are specifically designed to assist an insurance company in objectively evaluating the risks posed by policy applicants. Health care services are provided to the health care industry to aid in the diagnosis and treatment of patients. Substance abuse testing services are provided to both regulated and nonregulated employers who employ drug-screening guidelines.

Operating income (loss) of each line of business is computed as sales less directly identifiable expenses. In computing operating income (loss) of the lines of business, none of the following items have been allocated: general corporate expenses such as administrative, management, and information systems expenses; investment income; goodwill; or other income (expenses). Identifiable assets by line of business are those assets that are used in the Company's operations in each line of business. General corporate assets are principally cash and goodwill.

Following is a summary of line of business information as of and for the years ended December 31, 2001, 2000, and 1999 (in thousands):

(8) Quarterly Financial Data (Unaudited)

A summary of unaudited quarterly results of operations for 2001 and 2000 is as follows (in thousands except per share data):

|                                           
|2000:                                      
|Sales                                       | $ 40,581          
|Gross profit                                | 13,998            
|Earnings (loss) before income taxes         | 1,157             
|Net earnings (loss)                         | 418               
|Basic and diluted earnings (loss) per share | 0.04              

In the fourth quarter 2000, net earnings decreased approximately $1,300,000 due to adjustments in the Company's allowance for doubtful accounts and nonrecurring labor charges.

In the third quarter 2001, net earnings decreased due to a noncash warrant expense of $3,234,000 related to warrants issued to WCAS. Acquisition-related expenses included in the period were approximately $700,000, primarily for severance expense.

(9) Commitments and Contingencies

Tax Assessment

The Comptroller of the State of Texas has conducted an audit of LabOne for sales and use tax compliance for the years 1991 through August 1999, and contends that LabOne's insurance laboratory services are taxable under the Texas tax code. The Texas Comptroller has issued a tax audit assessment, including interest and penalties, of $568,000 that has been paid by the Company. The assessment does not include potential taxes due for periods thereafter, interest, nor the 10% penalty. Interest accrues at the rate of 12% per annum from the date the taxes were due. The Company estimates that an additional $29,000 will be assessed and has an adequate reserve at December 31, 2001. All amounts paid are under appeal as the Company argues that its services do not fit within the definition of insurance services under the Texas code. The assessment is in litigation in Travis County District Court. LabOne has filed a Motion for Summary Judgment, which is set for hearing the week of June 24, 2002. At this time, the Company is unable to predict the ultimate outcome of this appeal.

During 2000, the Internal Revenue Service performed a review of employment taxes paid by ExamOne World Wide of NJ, Inc., and proposed a $45,000 increase in tax for the quarters beginning March 31, 1992 through December 31, 1994. Effective July 30, 2001, the Internal Revenue Service issued a no change letter acquiescing that no additional tax was due.

Litigation

The Company has been a party to certain claims from competitors in the paramedical examination business regarding its relationships with independent contractors providing services to ExamOne. The Company has prevailed in such claims and believes that any outstanding matters will not materially affect the consolidated financial statements of the Company.

The Company is a party to various claims or lawsuits related to lab testing performed in the ordinary course of the Company's activities. The Company's management and legal counsel anticipate potential claims resulting from such matters that would not be covered by insurance, and have appropriately provided for these claims in the consolidated financial statements. The Company believes that the resolution of these matters will not materially affect the consolidated financial statements of the Company.

Leases

LabOne has several noncancelable operating leases, primarily for land and buildings, and other commitments that expire through 2004. Rental expense for these operating leases during 2001, 2000, and 1999 amounted to $2,335,000, $868,000, and $513,000, respectively.



Future minimum lease payments and other commitments under these agreements as of December 31, 2001 are:

|Year                | Amount       
|------------------- | -------------
|2002                | $   2,582,000
|2003                | 2,382,000    
|2004                | 1,550,000    
|2005                | 610,000      
|2006                | 555,000      
|2007 and thereafter | 2,793,000    
|                    | $ 10,472,000 

Leases are expected to be secured or replaced in the ordinary course of business as they expire.

(10) Subsequent Event

On January 23, 2002, LabOne acquired substantially all the assets of Bodimedex, Inc., a paramedical business located in Boston, Massachusetts. The paramedical service company was acquired for $3,400,000 including an amount held in escrow of $1,850,000. On January 29, 2002, $850,000 was released to Bodimedex, Inc. from escrow in satisfaction of obtaining dismissal from a specific legal action. On February 22, 2002, $500,000 was released.
