Notices

For so long as Notes in global
form are outstanding, notices to be given to holders will be given to the Trustee in accordance with its applicable policies in effect
from time to time. If Notes are issued in individual definitive form, notices to be given to holders will be deemed to have been given
upon the mailing by first class mail of such notices to holders of the Notes at their registered addresses as they appear in the registrar’s
records.

Optional Redemption

PGF will not be permitted
to redeem the Notes before their stated maturity, except as set forth below. The Notes will not be entitled to the benefit of any sinking
fund (we will not deposit money on a regular basis into any separate account to repay your Notes). In addition, you will not be entitled
to require us to repurchase your Notes from you before the stated maturity.

On and after the redemption
date, interest will cease to accrue on the Notes or any portion of the Notes called for redemption (unless we default in the payment of
the redemption price and accrued and unpaid interest). On or before the business day prior to any redemption date, we will deposit with
the trustee money sufficient to pay the redemption price of and (unless the redemption date shall be an interest payment date) accrued
and unpaid interest to the redemption date on the Notes to be redeemed on such date. If less than all of the Notes of any series are to
be redeemed, the Notes to be redeemed shall be selected by the trustee by such method as set forth in the indenture.
