The original Complaint alleges that OCA and certain of its officers violated federal securities laws. Specifically, the Complaint alleges that certain of defendants' public statements during the Class Period were materially false and misleading because (i) defendants engaged in improper accounting practices (OCA, which has not yet filed its annual report for 2004, has announced that it will restate its financial results for the first three quarters of 2004); (ii) certain journal entries in OCA's general ledger were improperly recorded; (iii) certain data provided to OCA's accounting firm had been improperly changed; and (iv) OCA could not ascertain its true financial condition because it lacked adequate internal controls. As a result, OCA's patient receivables and patient revenue from its affiliated orthodontic and pediatric dental practices were materially overstated.

The complaint further alleges that on or around June 7, 2005, OCA announced that (i) it was further delaying the filing of its annual report; (ii) it intends to restate its financial results for the first three quarters of 2004; and (iii) its Chief Operating Officer had been placed on administrative leave. After this announcement, the stock plummeted over 38%.
