(NASD OTC BB: BITI) ("Bio-Imaging" or the "Company") announced today that its Board of Directors has appointed PricewaterhouseCoopers LLP as the Company's independent auditors for the fiscal year ending December 31, 2002, replacing Arthur Andersen LLP, effective immediately. The decision was made at the recommendation of the Audit Committee of the Company's Board of Directors. Commenting on the change, Dr. David E. Nowicki, Chairman of the Board of Directors, said, "The appointment of PricewaterhouseCoopers was made after extensive Audit Committee interviews with a number of top-ranked public accounting firms. PricewaterhouseCoopers was chosen due to its reputation for excellent service, professionalism, industry expertise, and to ensure that the Company's stockholders continue to have the utmost confidence in the integrity of the Company's financial statements. We are confident that PricewaterhouseCoopers will provide Bio-Imaging with outstanding support, and we look forward to beginning our audit relationship with them." The decision to change auditors was not the result of any disagreement between Bio-Imaging and Arthur Andersen on any matter of accounting principles or practices, financial statement disclosures, or auditing scope or procedure. Dr. Nowicki added "Arthur Andersen has provided quality service as independent auditors to Bio-Imaging since 1998. Bio-Imaging has valued its relationship with Andersen and we have high regard for the Andersen audit team's work ethic and professionalism. However, in light of the current uncertainties at Arthur Andersen, we felt it was in the best interest of our Company and our stockholders to make the change now."
