LEGAL OWNERSHIP</div>

In this prospectus and in any prospectus supplement,
when we refer to the “holders” of securities as being entitled to specified rights or payments, we mean only the actual legal
holders of the securities. While you will be the holder if you hold a security registered in your name, more often than not the registered
holder will actually be either a broker, bank, other financial institution or, in the case of a global security, a depositary. Our obligations,
as well as the obligations of the trustee, any warrant agent, any transfer agent, any registrar, any depositary and any third parties
employed by us or the other entities listed above, run only to persons who are registered as holders of our securities, except as may
be specifically provided for in a contract governing the securities. For example, once we make payment to the registered holder, we have
no further responsibility for the payment even if that registered holder is legally required to pass the payment along to you as a street
name customer but does not do so.

If we choose to issue, or the selling shareholders
choose to sell, preferred shares or common shares, they may be evidenced by ADRs and you will hold them indirectly through ADSs. The underlying
preferred shares or common shares will be directly held by a depositary. See “Description of Shares and American Depositary Shares
