Events of Default

Unless otherwise indicated in the applicable prospectus
supplement, the following will be events of default under the indenture with respect to each series of debt securities issued under the
indenture:

| ● | failure to pay when due any interest on any debt security of that series, continued for 30 days; |

| ● | failure to pay when due the principal of, or premium, if any, on, any debt security of that series; |

| ● | failure to perform any other covenant or agreement of ours under the indenture or the supplemental indenture with respect to that        
 series or the debt securities of that series, continued for 90 days after written notice to us by the trustee or holders of at least 25% 
 in aggregate principal amount of the outstanding debt securities of the series to which the covenant or agreement relates;               |

| ● | certain events of bankruptcy, insolvency or similar proceedings affecting us; and |

| ● | any other event of default specified in any supplemental indenture under which such series of debt securities is issued. |

Except as to certain events of bankruptcy, insolvency
or similar proceedings affecting us and except as provided in the applicable prospectus supplement, if any event of default shall occur
and be continuing with respect to any series of debt securities under the indenture, either the trustee or the holders of at least 25%
in aggregate principal amount of outstanding debt securities of such series may accelerate the maturity of all debt securities of such
series. Upon certain events of bankruptcy, insolvency or similar proceedings affecting us, the principal, premium, if any, and interest
on all debt securities of each series shall be immediately due and payable.

After any such acceleration, but before a judgment
or decree based on acceleration has been obtained by the trustee, the holders of a majority in aggregate principal amount of each affected
series of debt securities may waive all defaults with respect to such series and rescind and annul such acceleration if all events of
default, other than the non-payment of accelerated principal, have been cured, waived or otherwise remedied.

No holder of any debt securities will have any
right to institute any proceeding with respect to the indenture or for any remedy under the indenture, unless such holder shall have previously
