Description of Registrants Securities

General. Each share of the Company’s common stock has the same rights and privileges. Holders of the common stock do not have any preferences or any preemptive, redemption, subscription, conversion or exchange rights. All of the outstanding shares of common stock are fully paid and nonassessable. The Company’s common stock is listed on the New York Stock Exchange (“NYSE”) under the symbol “RDN.”

Voting Rights. The holders of common stock are entitled to vote upon all matters submitted to a vote of stockholders and are entitled to one vote for each share of common stock held. There is no cumulative voting.

Dividends. Subject to the prior rights and preferences, if any, applicable to shares of preferred stock or any series of preferred stock, the holders of common stock are entitled to participate ratably in all dividends, payable in cash, stock or otherwise, that may be declared by the Company’s board of directors out of any funds legally available for the payment of dividends. Each such distribution will be payable to holders of record as they appear on the Company’s stock transfer books on such record dates and dividend dates as may be fixed by the board of directors.

Liquidation and Distribution. If the Company voluntarily or involuntarily liquidates, dissolves or winds-up, or upon any distribution of assets, the holders of common stock will be entitled to receive, after distribution in full of the preferential amounts, if any, to be distributed to the holders of preferred stock or any series of preferred stock, all of the remaining assets available for distribution equally and ratably in proportion to the number of shares of common stock held by them.

General. The preferred stock authorized under the Certificate of Incorporation may be issued from time to time in one or more series. The Company’s board of directors has the full authority permitted by law to establish, without further stockholder approval, one or more series and the number of shares constituting each such series and to fix by resolution full or limited, multiple or fractional, or no voting rights, and such designations, preferences, qualifications, privileges, limitations, restrictions, options, conversion rights and other special or relative rights of any series of the preferred stock that may be desired. Subject to the limitation on the total number of shares of preferred stock which the Company has authority to issue under the Certificate of Incorporation, the board of directors is also authorized to increase or decrease the number of shares of any series, subsequent to the issue of that series, but not below the number of shares of such series then outstanding. In case the number of shares of any series is so decreased, the shares constituting such decrease will resume the status which they had prior to the adoption of the resolution originally fixing the number of shares of such series. The Company may amend from time to time the Certificate of Incorporation and Bylaws to increase the number of authorized shares of preferred stock or common stock or to make other changes or additions.
