#### Voting and Certain Other Rights
Prior to the delivery of shares of common stock under each purchase contract, such purchase contract shall not entitle the holder of the Corporate Units or Treasury Units to any rights of a holder of shares of the Company’s common stock, including, without limitation, the right to vote or receive any dividends or other payments or distributions or to consent to or to receive notice as a stockholder or other rights in respect of the Company’s common stock.

#### Agreed United States Federal Income Tax Treatment
Each beneficial owner of an Equity Unit, by accepting a beneficial interest therein, will be deemed to have agreed for United States federal, state and local income tax purposes (unless otherwise required by any taxing authority) (1) to be treated as the owner, separately, of each of the purchase contract, the related RSNs and the applicable ownership interests in the Treasury portfolio or Treasury security, as the case may be, (2) to treat the RSNs as indebtedness and (3) to allocate, as of the issue date, 100% of the purchase price paid for the Corporate Units to its ownership interest in the RSNs and 0% to each purchase contract, which will establish its initial tax basis in each purchase contract as $0 and the beneficial owner’s initial tax basis in the RSNs as $50. This position will be binding on each beneficial owner of each Equity Unit, but not on the IRS. See “Material United States Federal Income Tax Considerations.”

#### Repurchase of the Equity Units
The Company may purchase from time to time any of the Equity Units that are then outstanding by tender, in the open market, by private agreement or otherwise, subject to compliance with applicable law.
