DESCRIPTION OF SUBSCRIPTION RIGHTS We may issue subscription rights to purchase debt securities, common stock, preferred stock, other securities described in this prospectus or any combination thereof. These subscription rights may be issued independently or together with any other security offered by us and may or may not be transferable by the securityholder receiving the subscription rights in such offering. In connection with any offering of subscription rights, we may enter into a standby arrangement with one or more underwriters or other investors pursuant to which the underwriters or other investors may be required to purchase any securities remaining unsubscribed for after such offering. To the extent appropriate, the applicable prospectus supplement will describe the specific terms of the subscription rights to purchase shares of our securities offered thereby, including the following:

| • |     | the date of determining the securityholders entitled to the subscription rights distribution; |

| • |     | the price, if any, for the subscription rights; |

| • |     | the exercise price payable for the debt securities, common stock, preferred stock or other securities upon the 
 exercise of the subscription rights;                                                                           |

| • |     | the number of subscription rights issued to each securityholder; |

| • |     | the amount of debt securities, common stock, preferred stock or other securities that may be purchased per each 
 subscription right;                                                                                             |

| • |     | any provisions for adjustment of the amount of securities receivable upon exercise of the subscription rights or 
 of the exercise price of the subscription rights;                                                                |

| • |     | the extent to which the subscription rights are transferable; |

| • |     | the date on which the right to exercise the subscription rights shall commence, and the date on which the 
 subscription rights will expire;                                                                          |

| • |     | the extent to which the subscription rights may include an over-subscription privilege with respect to 
 unsubscribed securities;                                                                               |

 transferability, exchange and exercise of the subscription rights.                                          |
