 by this prospectus in an “at the market offering” as defined in Rule 415 under the Securities Act. Such offering may be made into an existing trading market for such securities in transactions at other than a fixed price, either:

| • |     | on or through the facilities of Nasdaq or any other securities exchange or quotation or trading service on which 
 such securities may be listed, quoted or traded at the time of sale; and/or                                      |

| • |     | to or through a market maker other than on Nasdaq or such other securities exchanges or quotation or trading 
 services.                                                                                                    |

We may directly solicit offers to purchase securities, or agents may be designated to solicit such offers. We will, in the accompanying 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 accompanying prospectus supplement, on a firm commitment basis. The distribution of the securities may be effected from time to time in one or more transactions:

| • |     | at a fixed price or prices, which may be changed; |

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

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

| • |     | at negotiated prices. |

Each prospectus supplement will describe the method of distribution of the securities and any applicable restrictions. The prospectus supplement with respect to the securities of a particular series will describe the terms of the offering of the securities, including the following:

| • |     | the name of the agent or any underwriters; |

| • |     | the public offering or purchase price and the proceeds we will receive from the sale of the securities; |

| • |     | any discounts and commissions to be allowed or re-allowed or paid to the 
 agent or underwriters;                                                   |

| • |     | all other items constituting underwriting compensation; |

| • |     | any discounts and commissions to be allowed or re-allowed or paid to 
 dealers; and                                                         |

| • |     | any exchanges on which the securities will be listed. |
