 States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance
with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon
the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United
States Treasury security, and rounded to three decimal places. PGF’s actions and determinations in determining the redemption price
shall be conclusive and binding for all purposes, absent manifest error.

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 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 for such series.

Redemption for Taxation Reasons

We have the option, subject to certain conditions, to redeem each series of the Notes in whole at their principal amount, plus accrued and unpaid interest, if any, to the relevant date of redemption, if and when, as a result of a change in, execution of, or amendment to, any laws or treaties or the official entry into effect, application or interpretation of any laws or treaties, we would be required to pay additional amounts related to the deduction of certain withholding taxesin respect of certain payments on such series of the Notes.

The optional tax redemption provision set forth in the accompanying prospectus under“Description of Debt Securities—Special
Situations—Optional Tax Redemption” shall apply with the reincorporation of PGF being treated as the adoption of a successor
entity. Such redemption shall not be available if the reincorporation was performed in anticipation of a change in, execution of or amendment
to any laws or treaties or the official application or interpretation of any laws or treaties in such new jurisdiction of incorporation
that would result in the obligation to pay additional amounts.

Amendments

Debt Securities—Special Situations—Modification and Waiver” in the accompanying prospectus
