Item 6.

Ownership of More than Five Percent on Behalf of Another Person

Prior to July 2008, the Shares were beneficially owned by the Reporting Person’s parents, Jim and Marcia Guzy (“Parents”), and held in an account maintained by them. In accordance with a court order entered on July 3, 2008, the Parents transferred the Shares into a restricted account as collateral to secure a judgment against them in favor of the Reporting Person. On February 9, 2009, the Parents and the Reporting Person (together, the “Parties”) entered into a Settlement Agreement (the “Settlement Agreement”) to resolve disputes between the Parties. On February 24, 2010, the Reporting Person transferred the Shares from the restricted account into an account maintained by him (the “Transfer”). The Parents disputed the legality of the Transfer and raised the issue before an arbitrator charged with resolving disputes under the Settlement Agreement. On March 11, 2010, the arbitrator ruled that notwithstanding the Transfer the Parents retained the right to purchase the Shares at their sole discretion from the Reporting Person for a cash price based on the fair market value of the Shares, unless the Reporting Person enters into a binding agreement to sell the Shares prior to receipt of notice from the Parents indicating exercise of their rights. The arbitrator also ruled that the Parties ownership of and rights to the Shares were unclear until March 11, 2010, the date of his order.
