such agreement will be set forth in more detail in any applicable prospectus supplement and any related free writing prospectus. The dealers participating in any sale of the securities may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. If required, we or the selling shareholders will include in any applicable prospectus supplement the names of the dealers and the terms of the transaction.

#### Direct Sales and Sales Through Agents
We or the selling shareholders may sell the securities directly. In that event, no underwriters or agents would be involved. We also may sell the securities through agents we designate from time to time to solicit offers from purchasers to purchase the securities included in this prospectus or to sell such securities in ordinary brokerage transactions on our or the selling shareholders’ behalf. If required, a prospectus supplement will name any agent involved in the offer or sale of the offered securities and will describe any commissions payable by us or the selling shareholders to the agent. Unless stated otherwise in any applicable prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We or the selling shareholders may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. We will describe the terms of any such sales in a prospectus supplement.

#### Delayed Delivery Contracts
We or the selling shareholders may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities from us or the selling shareholders at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in a prospectus supplement. Such prospectus supplement will describe the commission payable for solicitation of those contracts.

We or the selling shareholders may offer and sell any of the securities in connection with a remarketing upon their purchase, in accordance with a redemption or repayment by their terms or otherwise, by one or more remarketing firms acting as principals for their own accounts or as our or the selling shareholders’ agents. The name of any remarketing firm, the terms of any remarketing agreement and the compensation to be paid to the remarketing firm will be included in a prospectus supplement, as required.
