| · | whether the units if issued as a separate security 
 will be issued in fully registered or global form. |

The descriptions of the units
in this prospectus and in any prospectus supplement are summaries of the material provisions of the applicable unit agreements. These
descriptions do not restate those unit agreements in their entirety and may not contain all the information that you may find useful.
We urge you to read the applicable unit agreements because they, and not the summaries, define your rights as holders of the units. For
more information, please review the forms of the relevant unit agreements, which will be filed with the SEC promptly after the offering
of units and will be available as described in the section titled “Where You Can Find More Information.”

LEGAL OWNERSHIP OF SECURITIES</div>

We can issue securities in
registered form or in the form of one or more global securities. We describe global securities in greater detail below. We refer to those
persons who have securities registered in their own names on the books that we or any applicable trustee, depository or warrant agent
maintain for this purpose as the “holders” of those securities. These persons are the legal holders of the securities. We
refer to those persons who, indirectly through others, own beneficial interests in securities that are not registered in their own names,
as “indirect holders” of those securities.

As we discuss below, indirect
holders are not legal holders, and investors in securities issued in book-entry form or in street name will be indirect holders.

Book-Entry Holders

We may issue securities in
book-entry form only, as we will specify in the applicable prospectus supplement. This means securities may be represented by one or more
global securities registered in the name of a financial institution that holds them as depositary on behalf of other financial
