, as applicable: (1) the yield for the Treasury constant maturity
on H.15 exactly equal to the period from the redemption date to the relevant Par Call Date (the “Remaining Life”); or (2) if
there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding
to the Treasury constant maturity on H.15 immediately shorter than the Remaining Life and one yield corresponding to the Treasury constant
maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the relevant Par Call Date on a straight-line
basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no
such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity
on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15
shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity
from the redemption date.

If on the third business day preceding the redemption
date H.15 or any successor designation or publication is no longer published, PGF shall calculate the Treasury Rate based on the rate

such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the relevant Par Call
Date, as applicable. If there is no United States Treasury security maturing on the relevant Par Call Date but there are two or more United
States Treasury securities with a maturity date equally distant from such Par Call Date, one with a maturity date preceding such Par Call
Date and one with a maturity date following such Par Call Date, PGF shall select the United States Treasury security with a maturity date
preceding such Par Call Date. If there are two or more United States Treasury securities maturing on the relevant Par Call Date or two
or more United States Treasury securities meeting the criteria of the preceding sentence, PGF shall select from among these two or more
United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid
and asked prices for such United
