 noteholder. Each other default may be waived, on behalf of all noteholders, by noteholders of a majority in aggregate principal amount of the notes then outstanding. Cure of Defaults; Ability to Cure or Waive Before Event of Default Occurs For the avoidance of doubt, and without limiting the manner in which any default can be cured,

| • |     | a default consisting of a failure to send a notice in accordance with the terms of the indenture will be cured 
 upon the sending of such notice;                                                                               |

| • |     | a default in making any payment on (or delivering any other consideration in respect of) any note will be cured                                                                                                      
 upon the delivery, in accordance with the indenture, of such payment (or other consideration) together, if applicable, with “default interest” (as defined below under the caption “—Default Interest”) thereon; and |

| • |     | a default that is (or, after notice, passage of time or both, would be) a “reporting event of default”                                                                                      
 (as defined below under the caption “—Special Interest as Sole Remedy for Certain Reporting Defaults”) will be cured upon the filing of the relevant report(s) giving rise to such default. |

In addition, for the avoidance of doubt, if a default that is not an event of default is cured or waived before such default would have constituted an event of default, then no event of default will result from such default. Notice of Defaults If a default occurs, then we will, within 30 days after its first occurrence, notify the trustee, setting forth what action we are taking or propose to take with respect thereto. However, we will not be required to provide such notification at any time after such default is cured or waived. We must also provide the trustee annually with a certificate as to whether any defaults have occurred or are continuing. If a default occurs and is continuing and is actually known to a responsible officer of the trustee, then the trustee must notify the noteholders of the same within 90 days after it occurs or, if it is not actually known to a responsible officer of the trustee at such time, promptly (and in any event within 10 business days) after it becomes actually known to a responsible officer of the trustee. However, except in the case of a default in the payment of the principal of, or interest on, any note, the trustee may withhold such notice if and for so long as it in good faith
