LabOne Receives Financing Facility Totaling $80 Million
From Welsh, Carson, Anderson & Stowe.

LENEXA, Kan.--Aug. 31, 2001--LabOne, Inc. (NASDAQ: LABS), today announces the acquisition of Osborn Group, Inc., Olathe, Kan., a wholly-owned subsidiary of ChoicePoint, Inc. (NYSE:CPS), for $49 million in cash. Osborn Group is a leading provider of risk assessment services to the life insurance industry, with approximately $37 million in annual revenue.

LabOne is a leading provider of risk assessment services to the insurance industry, laboratory testing and other services for the healthcare industry and substance abuse testing services for employers. Its risk assessment services include high-quality laboratory testing, investigative services, teleunderwriting, underwriting case management, and paramedical examinations. These services provide critical data for the underwriting of insurance policies and claims processing. 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 operational overlap, LabOne expects to generate $5 to $10 million of annual cost savings from the acquisition.

"We are excited about the opportunity that this acquisition provides for LabOne and Osborn customers, employees, and our shareholders," said W. Thomas Grant II, the chairman, president and CEO of LabOne. "The combination of these two companies will allow us to utilize excess laboratory capacity and integrate our services and information technology platforms providing a broader array of services for our customers."

Welsh, Carson, Anderson & Stowe (WCAS) will invest a total of $50 million in preferred equity and subordinated debt in LabOne to fund the acquisition and related expenses of the transaction. In addition, WCAS maintains a right of first refusal to invest an additional $30 million in LabOne to fund future acquisitions. WCAS will invest $14 million in convertible preferred equity, $21 million in preferred equity, and $15 million in subordinated debt. The convertible preferred equity will be a Series B Convertible Preferred Stock, which will have a conversion price of $8.32 and a coupon of 8.0%, payable in kind. The preferred equity will have a coupon of 18%, payable in kind and upon receipt of shareholder approval, will convert to Series B Convertible Preferred Stock. The subordinated debt will pay a cash coupon of 11%. In addition, WCAS will receive 350,000 warrants with a nominal strike price.

LabOne will immediately seek a board-recommended vote from its shareholders to convert the preferred equity to Series B Convertible Preferred Stock, which will allow WCAS to directly nominate or elect three members and jointly nominate another member of a newly constituted seven-member board of directors. Of the three WCAS board members, up to two may be directly elected by WCAS and the other(s) may be nominated by WCAS for election by the common shareholders. Upon shareholder approval, WCAS will hold approximately 29% of the outstanding equity of the Company. Additionally, the executive committee of the new board of directors will be composed of W. Thomas Grant II, James R. Seward, currently a director, and Paul B. Queally, WCAS.

"We are excited to have a world-class firm like Welsh, Carson, Anderson, & Stowe as our partner," said Mr. Grant. "The firm's extensive healthcare investing experience, market credibility, and significant capital resources will greatly enhance our ability to execute our long-term growth strategy. They have proven to be excellent partners in the building of healthcare companies and creating value for all shareholders."

"We are very enthusiastic about the opportunity to partner with LabOne in this transaction, which creates an exciting and well-positioned services company," said a WCAS spokesperson. "LabOne is already a preeminent provider of risk assessment services and this transaction will enhance its strategic position and create additional growth opportunities."
