| • |     | any provision for the issuance, payment, settlement, transfer or exchange of the units or of the securities 
 comprising the units; and                                                                                   |

PLAN OF DISTRIBUTION We and the selling stockholders may sell securities:

| • |     | through underwriters; |

| • |     | through dealers; |

| • |     | through agents; |

| • |     | directly to purchasers; or |

| • |     | through a combination of any of these methods of sale. |

In addition, we may issue the securities as a dividend or distribution or in a subscription rights offering to our existing securityholders. We or the selling stockholders may directly solicit offers to purchase securities or agents may be designated to solicit such offers. We will, in the prospectus supplement relating to such offering, name any agent that could be viewed as an underwriter under the Securities Act and describe any commissions that we must pay. Any such agent will be acting on a best efforts basis for the period of its appointment or, if indicated in the applicable prospectus supplement, on a firm commitment basis. This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement. The distribution of the securities may be effected from time to time in one or more transactions:

| • |     | at a fixed price or prices that may be changed from time to time; |

| • |     | at market prices prevailing at the time of sale; |

| • |     | at prices related to such prevailing market prices; or |

| • |     | at negotiated prices. |
