 We and any applicable trustee have no responsibility for any aspect of the depositary’s actions or for its records of ownership          
 interests in a global security. We and the trustee also do not supervise the depositary in any way.                                      |

 will, require that those who purchase and sell interests in a global security within its book-entry system use immediately available funds, 
 and your broker or bank may require you to do so as well.                                                                                   |

 depositary’s book-entry system, and through which an investor holds its interest in a global security, may also have their own policies  
 affecting payments, notices and other matters relating to the securities. There may be more than one financial intermediary in the chain 
 of ownership for an investor. We do not monitor and are not responsible for the actions of any of those intermediaries.                  |

Special Situations When a Global Security Will Be Terminated

In a few special situations
described below, the global security will terminate, and interests in it will be exchanged for physical certificates representing those
interests. After that exchange, the choice of whether to hold securities directly or in street name will be up to the investor. Investors
must consult their own banks, brokers or other financial institutions to find out how to have their interests in securities transferred
to their own name, so that they will be direct holders. We have described the rights of holders and street name investors above.

The global security will terminate
when the following special situations occur:

| · | if the depositary notifies us that it is unwilling,                                                                                             
 unable or no longer qualified to continue as depositary for that global security and we do not appoint another institution to act as depositary 
 within 90 days;                                                                                                                                 |

| · | if we notify any applicable trustee that we wish 
 to terminate that global security; or            |

| · | if an event of default has occurred with regard                                     
 to securities represented by that global security and has not been cured or waived. |

The applicable prospectus
supplement may also list additional situations for terminating a global security that would apply only to the particular series of securities
covered by the prospectus supplement. When a global security terminates, the depositary, and not we or any applicable trustee, is
