### DESCRIPTION OF PURCHASE CONTRACTS AND PURCHASE UNITS
We may issue purchase contracts representing contracts obligating holders, subject to the terms of such purchase contracts, to purchase from us, and us to sell to the holders, a specified or varying number of our common stock, preferred stock or other securities described in this prospectus at a future date or dates. Alternatively, the purchase contracts may, subject to the terms of such purchase contracts, obligate us to purchase from holders, and obligate the holders to sell to us, a specified or varying number of common stock, preferred stock or other securities described in this prospectus. The price per unit of our common stock, preferred stock or other securities described in this prospectus and number of units may be fixed at the time the purchase contracts are entered into or may be determined by reference to a specific formula set forth in the purchase contracts. We may issue the purchase contracts separately or as part of units, which we refer to as “purchase units,” consisting of a purchase contract and other securities or obligations issued by us or third parties, including government securities, in each case, securing the holders’ obligations to purchase the relevant securities under the purchase contracts. The purchase contracts may require us to make periodic payments to the holders of the purchase contracts or purchase units or vice versa, and such payments may be unsecured or prefunded on some basis.

Any applicable prospectus supplement will describe the terms of any purchase contract or purchase units. The description in a prospectus supplement will not necessarily be complete and will be qualified in its entirety by reference to the purchase contracts, and, if applicable, collateral arrangements and depositary arrangements, relating to the purchase contracts or purchase units. We will file any documents governing or establishing the term of any purchase contract or purchase unit, or the form thereof, with the SEC, and you should read these documents for provisions that may be important to you. See “Where You Can Find More Information.”
