The Holder of each Restricted Security, by such Holder's acceptance thereof, agrees to be bound by such restrictions on transfer. All Restricted Securities shall bear the legend set forth on the face of the Restricted Securities. Accredited Investors that are not QIBs may hold interests in the Initial Bonds only in definitive form. Any beneficial interest in a Global Bond that is a Restricted Security and is transferred to an Accredited Investor which is not a QIB will be delivered in the form of a definitive Bond and will cease to be an interest in such Global Bond. A holder of a beneficial interest in a Global Bond may exchange such beneficial interest for one or more definitive Bonds if (i) the Issuer notifies the Trustee in writing that the Registered Depositary is unwilling or unable to continue as depositary for such Global Bond, or the Registered Depositary ceases to be a "Clearing Agency" registered under the Exchange Act and a successor depositary is not appointed by the Issuer within 90 days of such notice or cessation or (ii) the Issuer, at its option, notifies the Trustee in writing that it elects to cause the issuance of definitive Bonds. If an exchange of a Global Bond for a definitive Bond is made pursuant to clauses (i) or (ii) above, then, upon surrender by the Registered Depositary of any beneficial interest in the Global Bonds, definitive Bonds will be issued to each person that the Registered Depositary identifies as the beneficial owner of the Bonds represented by the Global Bonds. Upon any such issuance, the Trustee will be required to register such definitive Bonds in the name of such person or persons (or nominee of any thereof) and cause the same to be delivered thereto. Unless determined otherwise by the Company in accordance with applicable law, each such Global Bond and all definitive Bonds, upon transfer or exchange of beneficial interests in a Global Bond (other than for an Exchange Bond) will bear the legend set forth on the face of the Restricted Securities. Each Holder of a definitive Bond or a beneficial interest in a Global Bond that is a Restricted Security will be deemed to have represented and agreed to offer, sell, pledge or otherwise transfer such Initial Bonds or beneficial interest only in accordance with the legend set forth on the face of the Restricted Securities. Upon the transfer, exchange or replacement of definitive Bonds bearing the legend, or upon request for removal of the legend on a definitive Bond, the Trustee will deliver Bonds that do not bear such legend if the Trustee has been provided evidence satisfactory to the Company (which may include an opinion of counsel) that neither the legend nor the restrictions on transfer set forth therein are required to ensure compliance with the Securities Act.
