FOR IMMEDIATE RELEASE:

DATATRAK INTERNATIONAL, INC. ANNOUNCES PLANS TO DEREGISTER ITS COMMON SHARES

CLEVELAND, Ohio... August 3, 2009... DATATRAK International, Inc., a technology and services company focused on global eClinical solutions for the clinical trials industry, today announced that it intends to file a Certificate and Notice of Termination of Registration on Form 15 with the Securities and Exchange Commission (“SEC”) to voluntarily terminate the registration of its common shares and related preferred share purchase rights and suspend its reporting obligations under the Securities Exchange Act of 1934. The Company is eligible to deregister its securities because it has fewer than 300 shareholders of record. This announcement follows the filing of a Form 25-NSE by the NASDAQ Stock Market, LLC (“NASDAQ”) on July 28, 2009 to delist the Company’s common shares from The NASDAQ Capital Market. The Form 25-NSE will become effective on August 7, 2009. The Company intends to file the Form 15 as soon as reasonably practicable, subject to its satisfaction of certain regulatory requirements.

Upon the filing of the Form 15, the Company’s obligations to file certain reports with the SEC, including annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K will immediately be suspended. In the future, DATATRAK intends to make public its quarterly and annual financial results as well as any significant corporate developments by posting such information on its website. The Company expects the deregistration of its common shares and preferred share purchase rights to become effective 90 days after filing the Form 15. DATATRAK’s common shares have been trading on the Pink Sheets Electronic Markets since being suspended from NASDAQ on June 4, 2009. The Company anticipates its common shares will continue to be quoted on the Pink Sheets Electronic Markets after deregistration. There can be no guarantee, however, that any broker will continue to make a market in the Company’s common shares and that trading will continue.

Commenting on the announcement, Laurence Birch, DATATRAK’s Interim Chief Executive Officer, said “The decision by the Board of Directors of the Company to deregister was made after careful consideration of the advantages and disadvantages of being a SEC reporting company including the high costs and demands on management time arising from compliance with the many SEC and Sarbanes-Oxley requirements. The current economic climate has not only impacted the capital markets, but the clinical trial industry as well. As such, we are constantly looking for ways to reduce costs and increase shareholder value as we continue to focus our efforts on growing the core business.”
