The total amount of accrued and unpaid interest to be paid by PGF, together with the total amount of cash to be paid by PGF in lieu of fractional amounts of New Notes, will be approximately U.S.$71,246,761.93 (excluding amounts payable in respect of Old Notes that may be tendered pursuant to the Guaranteed Delivery Procedures).

The actual aggregate principal amounts of New Notes that will be issued, and the total amount of cash , including accrued and unpaid interest, that will be paid, on the Settlement Date, are subject to change based on deliveries under the Guaranteed Delivery Procedures and final validation of tenders. PGF will not receive any cash proceeds from the Exchange Offers.

Given the amount of New Notes expected to be issued on the Settlement Date, the condition to consummate the Exchange Offers relating to the minimum issue requirement described in the Offering Memorandum, along with the condition relating to the settlement of the Cash Offers, are expected to be satisfied on the Settlement Date. All the other conditions for the consummation of the Exchange Offers were satisfied on the Expiration Date.
