LabOne's business plan is to be the premier provider of certified and accredited, cost effective laboratory and information services to life and health insurance companies, employers, third party administrators, government agencies, hospitals, physician practices and occupational health clinics.

LabOne's risk assessment services comprise underwriting support services including teleunderwriting, specimen collection and paramedical examinations, laboratory testing, telephone inspections, motor vehicle reports and medical record retrieval to the insurance industry. The laboratory tests performed and data gathered by the Company are specifically designed to assist an insurance company in objectively evaluating the mortality and morbidity risks posed by policy applicants.

LabOne operates highly automated and centralized laboratory facilities, which the Company believes has significant economic advantages over other laboratory competitors. Furthermore, this centralized approach provides the ability to transmit detailed patient outcomes to managed care companies in easily accessible electronic formats. LabOne markets its clinical testing services to managed care companies, insurance companies, self-insured groups, hospitals and physicians.

LabOne's clinical services also include substance abuse testing ("SAT") provided to employers to support their drug free workplace programs. 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. Additionally, the Company can provide background checks, social security number verification and other pre-employment data required by employers.

SECOND QUARTER ANALYSIS

Revenue for the quarter ended June 30, 2004, was $117.5 million compared to $84.0 million in the second quarter 2003. The increase of $33.5 million, or 40%, was due to increases in clinical healthcare revenue of $19.4 million, risk assessment revenue of $10.4 million and clinical SAT revenue of $3.8 million. Risk assessment revenue increased to $66.1 million from $55.7 million in the second quarter 2003 due primarily to increases of $5.7 million in other insurance services and $4.7 million in paramedical services, partially offset by a decrease in insurance laboratory services of $0.1 million. Other insurance services increased primarily due to growth in medical records retrieval and teleunderwriting services. Paramedical services revenue increased due to an increase in the number of paramedical exams performed from new customer accounts and the acquisition of a Canadian paramedical provider. Insurance laboratory revenue decreased due to a 4% decline in the average revenue per applicant partially off set by a 1% increase in the total number of insurance applicants tested by the Company. During the second quarter 2004, healthcare services revenue increased to $40.6 million from $21.3 million in 2003 due to the acquisition of Alliance Laboratory Services in January 2004 and a 19% increase in organic testing volumes. Alliance Laboratory Services accounted for $14.3 million of the revenue increase, and increased sales to new and existing healthcare customers accounted for $5.0 million of the revenue increase. SAT revenue increased $3.8 million to $10.8 million in the second quarter 2004 from $7.0 million in 2003 due to the addition of Northwest Toxicology and an 11% increase in organic testing volumes. Northwest Toxicology accounted for $3.2 million of this increase. Total laboratory services revenue from risk assessment and clinical was $74.1 million as compared to $51.0 million in the second quarter 2003.

Cost of sales increased $23.5 million, or 41%, in the second quarter 2004 as compared to the prior year, due primarily to the acquisitions of Alliance Laboratory Services and Northwest Toxicology, and increases in paramed collections, physician statement fees and payroll expense. Paramedical services increased primarily due to continued growth of the ExamOne paramedical operations. Physician statement fees increased due to growth of sales of attending physician statement services. Payroll increased due to increased specimen volume in the healthcare laboratory testing segment and growth of teleunderwriting and medical records retrieval services. Risk assessment cost of sales, including all of the above mentioned factors, increased to $47.5 million in 2004 from $39.4 million in the second quarter 2003. Clinical healthcare cost of sales increased to $25.8 million as compared to $12.8 million in the second quarter 2003 primarily due to the addition of Alliance Laboratory Services. Clinical SAT cost of s ales expenses increased to $7.4 million as compared to $4.9 million in the second quarter 2003 primarily due to the addition of Northwest Toxicology.

As a result of the above factors, gross profit for the quarter increased $10.0 million, or 37%, from $26.9 million in 2003 to $36.9 million in 2004. Risk assessment gross profit increased $2.3 million, or 14%, to $18.6 million in the second quarter 2004.

Clinical SAT gross profit increased $1.3 million, or 62%, to $3.4 million in 2004 from $2.1 million in the second quarter last year.

Selling, general and administrative expenses increased $7.3 million, or 40%, in the second quarter 2004 as compared to the prior year. This increase is primarily due to increases in payroll, amortization and bad debt expenses. Risk assessment overhead expenditures increased to $5.0 million in 2004 from $4.5 million in the second quarter 2003. Clinical healthcare overhead expenditures increased to $9.4 million as compared to $4.9 million in 2003 due to the acquisition of Alliance Laboratory Services and an increase in payroll expense. Clinical SAT overhead expenditures increased to $1.6 million as compared to $0.8 million in 2003 due to the acquisition of Northwest Toxicology. Corporate overhead expenses increased to $9.7 million from $8.1 million in the second quarter 2003 primarily due to higher payroll, telephone and expenses related to compliance with the Sarbanes-Oxley Act of 2002.

Operating earnings increased from $8.5 million in the second quarter 2003 to $11.2 million in 2004. Risk assessment services operating earnings were $13.6 million in 2004 as compared to $11.8 million in the second quarter 2003.

The combined effect of the above factors resulted in net earnings of $6.3 million, or $0.36 per diluted share in the second quarter 2004, compared to $5.0 million, or $0.30 per diluted share in 2003. Convertible preferred dividends in the second quarter 2003 were $0.8 million and earnings available to common shareholders were $4.3 million.

Risk assessment overhead expenditures increased to $9.8 million in 2004 from $9.0 million in the first six months of 2003.

The combined effect of the above factors resulted in net earnings of $12.2 million, or $0.70 per diluted share in the first six months of 2004, compared to $9.6 million, or $0.57 per diluted share in 2003. Convertible preferred dividends in the first six months of 2003 were $1.6 million and earnings available to common shareholders were $8.0 million.

LabOne's working capital position increased by $4.0 million to $52.1 million as of June 30, 2004 from $48.1 million as of December 31, 2003 due to an increase in accounts receivable, partially offset by an increase in accounts payable. Net cash provided by operations was $21.3 million as compared to $11.9 million in the first six months of 2003. The increase is due to higher net income and depreciation, offset by an increase in working capital associated with increased revenue and acquisitions completed during the first quarter.

During the first six months of 2004, the Company spent $60.0 million on acquisitions and $8.8 million for capital expenditures. Acquisitions included $43.9 million for Alliance Laboratory Services and $12.2 million for Northwest Toxicology. During the first six months of 2003, the Company spent $1.4 million on acquisitions and $3.8 million for capital expenditures. The Company expects to spend approximately $20 million for the land, building construction, furnishings, equipment and information technology systems for a new laboratory facility in Cincinnati, Ohio to be completed in the second quarter of 2005.

During June 2004, the Company issued $90 million of 3.50% convertible senior debentures due June 15, 2034 in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933. During July 2004, the initial purchasers exercised their option to purchase an additional $13.5 million of the debentures. The debentures may be converted, under certain circumstances, into a combination of cash and common stock of the Company at an initial rate equivalent to a conversion price of $39.30 per share of common stock, subject to certain adjustments. Holders may convert the debentures if the common stock price exceeds 130% of the conversion price for 20 trading days in the 30 trading day period ending on the last trading day of the preceding fiscal quarter. Upon conversion, the Company will deliver cash equal to the lesser of the aggregate principal amount of debentures to be converted and the conversion obligation, and common stock in respect of the remainder, if any, of th e conversion obligation. The Company may not redeem the debentures prior to June 20, 2009. Holders of the debentures may require the Company to repurchase some or all of the debentures on June 15, 2011, 2014 and 2024 and upon certain specified corporate transactions. The Company used the net proceeds from the offering to reduce borrowings under its credit facility and for general corporate purposes.

As of June 30, 2004, borrowings under the Company's revolving credit facility were $2.7 million. Borrowings had increased from $47.0 million as of December 31, 2003 to $95.7 million as of March 31, 2004 primarily to fund acquisitions. The line of credit bears variable interest which, as of July 30, 2004, was 3.3% and requires a commitment fee of 0.5% on the unused portion of the commitment. Based on covenants, $46.3 million of the remaining $147.3 million was available for borrowing as of June 30, 2004, under the Company's $150 million line of credit.

Interest on the industrial revenue bonds issued to finance the construction of the Company's Lenexa facility is based on a taxable seven-day variable rate which, including letter of credit and remarketing fees, was approximately 2.4% as of July 30, 2004.

As of June 30, 2004, LabOne had total cash and cash equivalents of $3.1 million as compared to $4.7 million as of December 31, 2003. The Company expects to fund operations from a combination of cash flows from operations and short-term borrowings.

As of June 30, 2004, LabOne's liability subject to variable interest rates was $13.5 million. The associated market risk exposure is not considered to be material. A foreign currency risk exposure exists due to sales in Canada 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.

The Company maintains disclosure controls and procedures that are designed for information required to be disclosed in the Company's reports filed pursuant to the Securities Exchange Act of 1934, as amended, to be recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms. Disclosure controls and procedures also are designed for such information to be accumulated and communicated to the Company's management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met.

Management of the Company, including the Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of the Company's disclosure controls and procedures as of the end of the period covered by this report. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures were effective as of the end of the period covered by this report to provide reasonable assurance that the control system's objectives would be met.

There were no changes in the Company's internal controls over financial reporting during the second quarter of fiscal 2004 that materially affected, or that are reasonably likely to materially affect, the Company's internal control over financial reporting.

During the third quarter of 2004, the Company's internal auditors identified a reportable condition in the design and operation of general computer controls related to program changes and access security. The condition is not considered a material weakness. The Company believes it has mitigating controls and procedures in place, has implemented certain changes in security access and change control, and has plans for completion of remediation during the third quarter.

Pursuant to a Purchase Agreement dated June 21, 2004, (attached as Exhibit 4.2 to LabOne's Form 8-K Current Report filed June 28, 2004) the Company offered $90 million in principal amount of 3.50% convertible senior debentures due June 15, 2034 in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933. By exercise of an option issued with the debentures, an additional $13.5 million principal amount of the debentures was purchased by the initial purchasers on July 8, 2004.

The debentures may be converted, under certain circumstances, into a combination of cash and common stock of the Company at an initial rate equivalent to a conversion price of $39.30 per share of common stock, subject to certain adjustments. The Company may not redeem the debentures prior to June 20, 2009. Holders of the debentures may require the Company to repurchase some or all of the debentures on June 15, 2011, 2014 and 2024 and upon certain specified corporate transactions.

The Company used approximately $87 million of the initial proceeds of the offering to reduce borrowings under its credit facility. The additional proceeds of approximately $13 million were used by the Company to pay the remaining borrowings under its credit facility and for general corporate purposes. The Company may in the future re-borrow a portion of these funds under its credit facility for the repurchase of shares of its common stock.

For a further description of the terms of the debentures, see the Indenture filed as Exhibit 4.1 to LabOne's Form 8-K Current Report filed June 28, 2004.
