Commitments and Contingencies

The Company has employment and/or severance agreements with certain key executives as of March 31, 2013. These agreements provide for base salaries and in some cases performance bonuses. These agreements also provide for severance compensation ranging from 6 to 24 months after termination.

The Company has standby letters of credit outstanding of $1,519 which are fully collateralized by domestic certificates of deposit.

The Company has, in the ordinary course of its business, disputed certain billings from carriers and has recorded the estimated settlement amount of the disputed balances. The settlement estimate is based on various factors, including historical results of prior dispute settlements. The amount of such charges in dispute at March 31, 2013 was $5,535. The Company believes that the ultimate settlement of these disputes will be at amounts less than the amount disputed and has accrued the estimated settlement in accrued expenses and other current liabilities at March 31, 2013. It is possible that actual settlements of such disputes may differ from these estimates and the Company may settle at amounts greater than the estimates.

The Company has entered into commercial agreements with its principal vendor under which it purchases certain services that it had previously leased under the unbundled network platform provisions of the Telecommunications Act of 1996 as well as special access services. The agreements require certain minimum purchase obligations. The Company is currently operating under an extension of its commercial agreement with its principal vendor while it negotiates a new multi-year arrangement.
