FIRST AMENDMENT TO BENEFIT EQUALIZATION PLAN

This amendment to the Federal Home Loan Bank of Topeka Benefit Equalization Plan
is adopted by the Federal Home Loan Bank of Topeka as of the date last written
below, the same to be effective as of January 1, 2008.

WHEREAS, Federal Home Loan Bank of Topeka (hereinafter, the “Bank”), previously
established the Federal Home Loan Bank of Topeka Benefit Equalization Plan
(hereinafter, the “Plan”) for the exclusive benefit of its members and their
beneficiaries, which Plan was most recently amended and restated effective as of
March 23, 2006; and

WHEREAS, the Bank retained the power to amend and/or terminate the Plan; and

WHEREAS, the Bank now desires to amend the Plan to clarify or change provisions
regarding the deferral of Members’ Incentive Compensation and employer
contributions matching Members’ deferred amounts;

NOW, THEREFORE, the Plan is hereby amended, effective January 1, 2008, as
follows:

1.   Notwithstanding any language in the Plan to the Contrary, Members shall be
allowed to make deferrals under Sections 4.01 or 4.02 from Incentive
Compensation; provided, the Member must make a deferral election before
December 31 of the calendar year preceding the calendar year in which the
Incentive Compensation is earned. The Member shall elect the amount to be
deferred, which may be expressed as a dollar amount or a percentage of the
Member’s total Incentive Compensation, as well as the time and form of payment
of the amount deferred.

2.   Notwithstanding any language in the Plan to the contrary, a Member’s
matching contribution credited under Section 4.05(a) shall be calculated based
on the Member’s total annual compensation (other than Incentive Compensation)
and actual deferral elections for the applicable Plan Year, disregarding IRC
Limitations. The matching amount shall be offset by any matching contribution
actually made to the Thrift Plan, but the amount of the offset shall not exceed
the dollar limit under IRC Section 402(g) for that Plan Year.

IN WITNESS WHEREOF, the Bank has caused this First Amendment to be signed by its
duly authorized officer on this 19th day of December, 2007.
