Allan Kanner & Associates has extensive experience in class actions. Their recent cases can be viewed at www.kanner-law.com. The complaint which can also be viewed at www.kanner-law.com asserts claims against the Defendants under Sections 10(b) and 20(a) of the Securities and Exchange Act of 1934. The complaint alleges that during the Class Period, Defendants issued false and misleading financial statements and failed to present the Company's financial statements in conformity with Generally Accepted Accounting Principles ("GAAP"). In addition, Defendants' Sarbanes-Oxley certifications during the Class Period were false and misleading.

On June 7, 2005, before the opening of trading, OCA shocked the market by announcing it had determined that the amount of patient receivables reported at each of March 31, June 30, and September 30, 2004 was overstated by material amounts. Although the Company said that it has not yet determined the amount by which the receivables were overstated or their impact on patient revenue, the Company announced its Audit Committee's conclusion that, due to these overstatements, the previously issued quarterly financial statements for the first, second and third quarters of 2004 will need to be restated and should no longer be relied upon. OCA also announced that it had discovered other accounting errors, which it was still reviewing, and had placed its Chief Operating Officer, Bartholomew F. Palmisano, Jr., on administrative leave as of June 1, 2005.

In response to this news, OCA stock lost approximately 40% of its value on enormous trading volume of over 9 million shares, dropping $1.57 to close at $2.46. In fact, the stock hit a 52-week low during trading yesterday. Accordingly, as a result of the Company's misrepresentations, OCA investors have sustained tremendous losses, and stand to lose much more as the full extent and magnitude of the restatement and fraud is disclosed.
