Isolagen, Inc. specializes in the development and commercialization of autologous cellular therapies for soft and hard tissue regeneration (the "Isolagen Process"). Autologous cellular therapy utilizes a process whereby a patient's own cells are extracted, allowed to multiply and then injected into the patient. In January 2003, Defendants began phase I clinical trials aimed at demonstrating the safety and efficacy of using the Isolagen Process to treat dermal defects.

The original Complaint charges Isolagen and certain of its officers and directors with violations of the Securities Exchange Act of 1934. Specifically, the Complaint alleges that without solid clinical data developed under controlled conditions, the data gathered in the clinical trials would never meet the FDA's "adequate and well-controlled" criteria for acceptable clinical trials and the Company's business plan would lack credibility to the investment community. Defendants' own internal testing showed the Isolagen Process had demonstrated nowhere near the efficacy required to obtain FDA approval, which was needed to make the Company profitable. However, during the Class Period, Defendants touted the efficacy of the Isolagen Process both for dermal and dental treatments, running up the Company's stock price to a Class Period high of $12 per share on April 2, 2004.

The Complaint further alleges that on or around August 1, 2005, the Company disclosed that the preliminary results from its phase III clinical trial of the Isolagen Process for the treatment of contour deformities (wrinkles) had not met all four primary end points and that neither of the two dermal studies had achieved independent statistical significance. On this news, the Company's stock price plummeted more than 45%, from $5.50 per share to below $3 per share, on very high volume.

According to the Company’s FORM 10-K for the fiscal year ended December 31, 2008, the Company and certain of its current and former officers and directors are Defendants in class action cases pending in the United States District Court for the Eastern District of Pennsylvania. In August 2005 and September 2005, various lawsuits were filed alleging securities fraud and asserting claims on behalf of a putative class of purchasers of publicly traded Isolagen securities between March 3, 2004 and August 1, 2005. These lawsuits were Elliot Liff v. Isolagen, Inc. et al., C.A. No. H-05-2887, filed in the United States District Court for the Southern District of Texas; Michael Cummiskey v. Isolagen, Inc. et al., C.A. No. 05-cv-03105, filed in the United States District Court for the Southern District of Texas; Ronald A. Gargiulo v. Isolagen, Inc. et al., C.A. No. 05-cv-4983, filed in the United States District Court for the Eastern District of Pennsylvania, and Gregory J. Newman v. Frank M. DeLape, et al., C.A. No. 05-cv-5090, filed in the United States District Court for the Eastern District of Pennsylvania.

The Liff and Cummiskey actions were consolidated on October 7, 2005. The Gargiolo and Newman actions were consolidated on November 29, 2005. On November 18, 2005, the Company filed a motion with the Judicial Panel on Multidistrict Litigation (the “MDL Motion”) to transfer the Federal Securities Actions and the Keene derivative case to the United States District Court for the Eastern District of Pennsylvania. The Liff and Cummiskey actions were stayed on November 23, 2005 pending resolution of the MDL Motion. The Gargiulo and Newman actions were stayed on December 7, 2005 pending resolution of the MDL Motion. On February 23, 2006, the MDL Motion was granted and the actions pending in the Southern District of Texas were transferred to the Eastern District of Pennsylvania, where they have been captioned In re Isolagen, Inc. Securities & Derivative Litigation, MDL No. 1741 (the “Federal Securities Litigation”).

On April 4, 2006, the United States District Court for the Eastern District of Pennsylvania appointed Silverback Asset Management, LLC, Silverback Master, Ltd., Silverback Life Sciences Master Fund, Ltd., Context Capital Management, LLC and Michael F. McNulty as lead Plaintiffs, and the law firms of Bernstein Litowitz Berger & Grossman LLP and Kirby McInerney & Squire LLP as lead Counsel in the Federal Securities Litigation.

On July 14, 2006, lead Plaintiffs filed a Consolidated Class Action Complaint in the Federal Securities Litigation on behalf of a putative class of persons or entities who purchased or otherwise acquired Isolagen common stock or convertible debt securities between March 3, 2004 and August 9, 2005. The Complaint purports to assert claims for securities fraud in violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 against Isolagen and certain of its former officers and directors. The Complaint also purports to assert claims for violations of Section 11 and 12 of the Securities Act of 1933 against the Company and certain of its current and former directors and officers in connection with the registration and sale of certain shares of Isolagen common stock and certain convertible debt securities. The Complaint also purports to assert claims against the underwriters of an April 2004 public offering of Isolagen common stock and a 2005 sale of convertible notes. On November 1, 2006, the Defendants moved to dismiss the Complaint. On September 26, 2007, the court denied the Company’s motions to dismiss the Complaint. On November 6, 2007, the court entered a scheduling order that provides for discovery to be complete by June 8, 2009. On February 4, 2008, lead Plaintiffs moved for class certification. On February 15, 2008, lead Plaintiffs dismissed without prejudice their claims against certain of the underwriters named as Defendants in the Federal Securities Class Action, but maintained claims against CIBC World Markets Corp. and UBS Securities LLC (the “Underwriters”).

On April 1, 2008, the court entered an order staying the schedule set forth in its November 6, 2007 order for a period of 90 days and directing the parties (together with the parties in the Beattie action) to participate in mediation before a private mediator. The mediation occurred on June 2, 2008 and June 5, 2008, at which the parties reached an agreement in principle to settle the Federal Securities Litigation. On October 23, 2008, the parties executed a definitive settlement agreement. In November 2008, the Company received settlement proceeds from its directors and officers liability insurance carrier, of which $4.4 million was paid to the class action Plaintiffs in December 2008 in accordance with the definitive settlement agreement. On March 25, 2009, the court entered an order and final judgment approving the settlement and dismissing the Federal Securities Litigation with prejudice.
