Item 8.01

Other Events

On March 12, 2013, we were served with a class action complaint filed in the U.S. District Court for the Western District of Pennsylvania (Case 1:13-cv-00071-SJM) by an individual plaintiff for itself and on behalf of all other “similarly situated” customers of ours. The complaint alleges, among other things, that we imposed unauthorized or excessive price increases and other charges on our customers in violation of the Illinois Consumer Fraud and Deceptive Business Practices Act and our implied contractual duties of good faith and fair dealing. The complaint seeks certification of the lawsuit as a class action and the award to class members of appropriate damages and injunctive relief.

The class action complaint has been filed in the wake of our recent settlement with the State of New York of an investigation under the New York False Claims Act (which the class action complaint describes at some length). In the settlement, which was announced by the New York Attorney General on January 8, 2013, we agreed, without admitting any liability, to pay $820,000 in refunds to customers and $1,580,000 in penalties to the State of New York to settle allegations that we had overcharged New York governmental customers over a 10-year period.

The New York investigation arose out of a qui tam (or “whistleblower”) complaint under the federal False Claims Act and comparable state statutes which were filed under seal in the U.S. District Court for the Northern District of Illinois in April 2008 by a former employee of ours. The complaint was filed on behalf of the United States and 14 states (including New York) and the District of Columbia. New York and Tennessee subsequently issued civil investigative demands to explore the allegations made on their behalf. The New York investigation resulted in the settlement described; Tennessee has not yet decided whether to join the Illinois action.

We believe that we have operated in accordance with the terms of our customer contracts and that the complaint is without merit. We intend to vigorously defend ourselves.
