In certain circumstances, participants may elect to withdraw all or a portion of their vested matching and profit sharing contributions that have been in their account for at least 24 months or after they have at least 60 months of participation in the Plan.

#### Forfeitures
As participants are immediately 100 percent vested in their account balance, there are no forfeitures.

#### Administrative Expenses
The Plan Administrator is responsible for filing all required reports on behalf of the Plan. The Company provides or pays for certain accounting, legal and management services on behalf of the Plan. The Company has not charged the Plan for these expenses or services. Loans and other transaction-specific fees are charged to the accounts of participants electing such transaction. Certain investment-related expenses, including management fees, are deducted from the funds in which the Plan invests, including those sponsored by an affiliate of Fidelity. These expenses are presented as a reduction of investment income.

#### Plan Termination
Although it has not expressed any intent to do so, with approval from the Board, TCUSA has the right under the Plan to discontinue contributions at any time and to terminate the Plan, subject to the provisions of ERISA.
