Noteholders who have not validly voted prior to the Early Consent Deadline can still vote on or prior to the Expiration Deadline will be entitled to receive the Late Consent Fee.

Senior Unsecured Notes

In respect of the Senior Unsecured Notes, in excess of 60% but under 75% in aggregate principal amount of the senior unsecured notes voted in favour of the applicable Extraordinary Resolution.  At this stage, the Extraordinary Resolution in respect of the Senior Unsecured Notes has not passed and there would be no quorum at the relevant initial noteholder meeting, however, subject to any further votes, there would be a quorum at the applicable adjourned meeting and the Extraordinary Resolution would pass.

Noteholders who have not validly voted prior to the Early Consent Deadline can still vote on or prior to the Expiration Deadline will be entitled to receive the Late Consent Fee.
