Riviera may, in the future, decide to purchase additional shares in the open market subject to market conditions and private transactions, tender offers or otherwise subject to applicable law. Any such purchases may be on the same terms as, or on terms that are more or less favorable to stockholders than, the terms of the offer. Whether Riviera makes additional repurchases in the future will depend on many factors, including but not limited to its business and financial performance, the business and market conditions at the time, including the price of the shares, and other factors Riviera considers relevant.
