The specific terms of any series of units offered will be described in the applicable prospectus supplement. If so described in a particular supplement, the specific terms of any series of units may differ from the general description of terms presented below. We urge you to read any prospectus supplement related to any series of units we may offer, as well as the complete unit agreement and unit certificate that contain the terms of the units. If we issue units, forms of unit agreements and unit certificates relating to such units will be incorporated by reference as exhibits to the registration statement, which includes this prospectus. Each unit that we may issue will be issued so that the holder of the unit is also is the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. Units will be issued pursuant to the terms of The unit agreement under which a unit agreement, which is issued may provide that the securities included in the unit may not be held or transferred separately separately, at any time or at any time before a specified date. A copy of the forms of the unit agreement and the unit certificate relating to any particular issue of units will be filed with the SEC each time we issue units, and you should read those documents for provisions that may be important to you.
