exercised debt warrants. Holders of debt warrants will
be required to pay any tax or governmental charge that may be imposed in connection with transferring the underlying debt securities in
connection with the exercise of the debt warrants.

Street name and other indirect holders of debt warrants should consult their bank or brokers for information on how to exercise their debt warrants.

Modification and Waiver

There are three types of changes we can make to
the debt warrant agreement and the debt warrants of any series.

Changes Requiring Your Approval.First, there are changes that cannot be made to your debt warrants or the debt warrant agreement under which they were issued without
your specific approval. These are the following types of changes:

| · | any increase in the exercise price; |

| · | any impairment of your ability to exercise the warrant; |

| · | any decrease in the principal amount of debt securities that can be purchased upon exercise of any debt 
 warrant;                                                                                                |

| · | any reduction of the period of time during which the debt warrants may be exercised; |

| · | any other change that materially and adversely affects the exercise rights of a holder of debt warrant 
 certificates or the debt securities that can be purchased upon such exercise; and                      |

<div align='center'>31</div>

| · | any reduction in the number of outstanding unexercised debt warrants whose consent is required for any 
 modification or amendment described under “Changes Requiring a Majority Vote.”                         |

Changes Requiring a Majority Vote.The
second type of change to the debt warrant agreement or debt warrants of any series is the kind that requires a vote of approval by the
holders of not less than a majority in number of the then outstanding unexercised debt warrants of that series. This category includes
all changes other than those listed above under “Changes Requiring Your Approval” or changes that would not adversely affect
holders of debt warrants or debt securities in any material respect.

Changes Not Requiring Approval. The
third type of change to the debt warrant agreement or debt warrants of any series does not require any vote or consent by the holders
of debt warrant certificates. This type is limited to curing any ambiguity, defect or inconsistency, making changes to conform the provisions
contained in the debt warrant agreement to the description of the debt warrants contained in this prospectus or an applicable prospectus
supplement and making changes that do not adversely affect the rights of holders of the debt warrant certificates in any material respect.
