 exercise price, delivery of the
equity warrant certificate (if any) properly completed and duly executed at the corporate trust office of the equity warrant agent or
any other office indicated in the applicable prospectus supplement and satisfaction of any other applicable requirements specified in
the applicable prospectus supplement, we will, as soon as practicable, forward the equity securities that can be purchased upon such exercise
of the equity warrants to the person entitled to them. If fewer than all of the equity warrants represented by the equity warrant certificate
are exercised, a new equity warrant certificate will be issued for the remaining equity warrants. Holders of equity warrants will be required
to pay any tax or governmental charge that may be imposed in connection with transferring the underlying equity securities in connection
with the exercise of the equity warrants.

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

Modification and Waiver

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

Changes Requiring Your Approval.
First, there are changes that cannot be made to your equity warrants or the equity 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 total number of preferred shares or common shares that can be purchased upon exercise 
 of any equity warrant;                                                                                    |

<div align='center'>34</div>

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

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

| · | any reduction in the number of outstanding unexercised equity 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 equity warrant agreement or equity 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 equity 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 equity warrants in any material respect
