1.28                            “ Termination of Employment ” means the severing of employment with the Bank and any Affiliates, voluntarily or involuntarily, for any reason.  A Termination of Employment will be deemed to have occurred if the facts and circumstances indicate that the Bank and the Member reasonably anticipate that no further services will be performed after a certain date or that the level of bona fide services the Member will perform for the Bank and its Affiliates after such date (whether as an employee or as an independent contractor) will permanently decrease to no more than 20% of the average level of bona fide services performed (whether as an employee or an independent contractor) over the immediately preceding 36-month period (or the full period of services to the employer if the Member has been providing services to the Bank and its Affiliates less than 36 months).  A Member will not be deemed to have incurred a Termination of Employment while he or she is on military leave, sick leave, or other bona fide leave of absence (such as temporary employment by the government) if the period of such leave does not exceed six months or such longer period as the Member’s right to reemployment with the Bank is provided either by statute or by contract.  For this purpose, a leave of absence is bona fide only if there is a reasonable expectation that the Member will return to employment at the conclusion of the leave.  If the period of leave exceeds six months and the Member’s right to reemployment is not provided either by statute or by contract, the Termination of Employment will be deemed to occur on the first date immediately following such six-month period.  Whether a Member incurs a Termination of Employment will be determined in accordance with the requirements of Code Section 409A.

SECTION 2 - ELIGIBILITY AND PARTICIPATION

2.1                                  Participation .  Each Member of the Plan on December 31, 2007 will continue as a Member on the effective date of the amendment and restatement of this Plan and thereafter to the extent eligible.  Each other Eligible Executive who is a participant in the Qualified Plan shall become a Member on the earlier of (a) the effective date of the Eligible Executive’s election to participate in the Thrift BEP or January 1, 2008, if later; or (b) the effective date as of which he or she is designated as a Member in the Plan by the Committee.  Within thirty (30) days of becoming a Member (or a participant in any similar non-account balance, non-qualified deferred compensation plan maintained by the Bank), the Member shall file an election with the Administrator designating how his or her Supplemental Benefit shall be paid.  If an Eligible Executive became a Member under clause (a) above and is subsequently designated as eligible for enhanced benefits under clause (b) above, the distribution election made in connection with his or her initial participation shall continue to apply.  The Surviving Spouse of a Member described above who dies prior to the Member’s Pension Commencement Date shall be eligible to receive a Supplemental Survivor Benefit, as set forth below.

2.2                                  Elections under Section 409A Transition Rules .  Pursuant to Internal Revenue Service (“IRS”) Notice 2005-1, Q&A-19(c), as extended by Notice of Proposed Rulemaking REG-158080-04 and IRS Notice 2007—86, a Member who (a) has not incurred a Termination of Employment or (b) has incurred a Termination of Employment but has neither entered pay status under the Plan nor had an annuity purchased in connection with his or her benefits under the Plan, may, in 2008, modify or make a new election regarding distribution of his or her Non-Grandfathered Supplemental Benefit at such time and in such form as the Administrator shall designate; provided, however, that no such distribution election made in 2008 may affect payments that the Member would otherwise receive in 2008 or cause payments to be made in 2008.  In addition, pursuant to Internal Revenue Service Notice 2005-1, Q&A-23, as extended, in the case of a distribution commencing on or before December 31, 2008 (or such later date as shall be permitted by the Administrator consistent with Code Section 409A and regulations thereunder), an election as to the time and form of payment of the Member’s benefit under the Qualified Plan shall govern distribution of the Member’s Non-Grandfathered Supplemental Benefit under this Plan, to the extent provided under the terms of the Prior Plan.

2.3                                  Cessation of Participation .  An Executive shall cease to be a Member in the Plan if (a) he or she incurs a Termination of Employment for any reason, (b) he or she remains in the service of a Bank but ceases to be an Eligible Executive as described in Section 1.11 due to a change in employment status, except to the extent that the Committee determines otherwise, or (c) the Plan is terminated or otherwise amended so that the Executive ceases to be eligible for participation; provided, however, that such individual shall continue to be a Member solely with respect to his or her benefits accrued through the date of such cessation, to the extent that such benefits are or become vested prior to the Member’s Termination of Employment.  Such cessation of participation shall be effective upon the date of the change in status described in clause (a) or (b) above, or upon the effective date of an amendment or termination of the Plan described in clause (c) above.

2.4                                  Vesting .  A Member (or his or her Beneficiary, as the case may be) shall be or become vested in his or her Supplemental Benefit as and to the same extent that he or she is vested under the terms of the Qualified Plan.

SECTION 3 - SUPPLEMENTAL RETIREMENT BENEFIT

3.1                                  Amount .  The Supplemental Retirement Benefit payable to a Member on or after his or her Normal Retirement Date shall be a monthly amount equal to the difference between either (a) or (b) below, as applicable, minus (c) below, adjusted as determined in accordance with Section 3.2 or 3.3, as applicable, where:

(a)                                   in the case of an Eligible Executive described in clause (a) of Section 1.11 who becomes a Member under clause (a) of Section 2.1 as a result of participation in the Thrift BEP, the monthly amount of the Qualified Plan Retirement Benefit to which the Member would have been entitled under the terms of the Qualified Plan if such benefit were computed by including in the definition of “Salary” any amounts voluntarily deferred by the Member under the Thrift BEP; or

(b)                                  in the case of an Eligible Executive described in clause (b) of Section 1.11 who becomes a Member under clause (b) of Section 2.1, the monthly amount of the Qualified Plan Retirement Benefit to which the Member would have been entitled under the terms of the Qualified Plan if such benefit were computed:

(i)                                      including in the definition of “Salary” any amounts voluntarily deferred by the Member under the Thrift BEP;

(ii)                                   without regard to Code Limitations;

(iii)                                including in the definition of “Salary” any Incentive Compensation paid during the applicable Plan Year (determined prior to any deferral under the Thrift BEP);

(iv)                               subject to the last paragraph of Section 3.1, by recognizing the Member’s years of service from his or her initial date of employment with any employer participating in the Qualified Plan to his or her date of membership in the Qualified Plan as benefit service under the Qualified Plan; provided, however, that in the case of an individual who becomes a Member on or after January 1, 2009, or who first becomes an Eligible Executive under clause (b) of Section 1.11 on or after that date, only the Member’s years of service with the Bank from initial date of employment with the Bank shall be so recognized; and

(v)                                  solely with respect to Executive Officers whose most recent date of hire by the Bank is prior to January 9, 2006 and who have continuously been an Executive Officer since January 1, 2008, by applying an increased annual pension accrual rate of two and three-eighths percent (2.375%); provided, however, that aggregate pension benefits payable to any Executive Officer (taking into account benefits determined under this Plan and the Qualified Plan, and from any other defined benefit pension plan in which the Member participated during any period of service taken into account in calculating the Member’s benefit hereunder) shall not exceed a percentage of the Member’s “High-3 Salary” (taking into account compensation described in clauses (i), (ii) and (iii) above) equal to sixty-five percent (65%) for Senior Vice Presidents, seventy percent (70%) for Executive Vice Presidents and eighty percent (80%) for the President;

MINUS

(c)                                   the monthly amount of the Qualified Plan Retirement Benefit payable to the Plan Member under the terms of the Qualified Plan.

Notwithstanding the foregoing, the amount of a Member’s Supplemental Retirement Benefit shall not be less than zero.  Subject to Section 6.1 and the provisions of Code Section 409A, the method for calculating a Member’s Non-Grandfathered Supplemental Benefit may be modified from time to time in an offer letter or employment agreement approved by the Committee and accepted by the Member, or other writing specifically approved by the Committee and making specific reference to this Plan.

If a Member (i) incurs a Termination of Employment and receives a full distribution of his or her Supplemental Retirement Benefit, and (ii) is later re-employed by the Bank and again becomes a Member, the Supplemental Retirement Benefit that accrues following such re-employment shall be calculated by disregarding any portion of his or her prior service with respect to which the Member’s Supplemental Retirement Benefit distribution was calculated.

3.2                                  Adjustment and Payment of Grandfathered Supplemental Retirement Benefits .  The amount of Grandfathered Supplemental Retirement Benefit to which a Member may be entitled, if any, shall be determined under the terms of the Prior Plan, and shall be subject to such adjustments to reflect the time and method of payment, and any “Active Service Death Benefit” (as defined in Article V, Section 4 (or successor provision) of the Qualified Plan), “Retirement Adjustment Payment” (as defined in Article V, Section 5 (or successor provision) of the Qualified Plan), or “Annual Increment” (as defined in Article V, Section 6(A) (or successor provision) of the Qualified Plan) as may apply under the terms of the Prior Plan and are both earned and vested prior to January 1, 2005.  An ad hoc cost of living adjustment (referred to as a “Single Purchase Fixed Percentage Adjustment” as defined in Article V, Section 6(B) (or successor provision) of the Qualified Plan) applicable under the Qualified Plan shall be taken into account solely to the extent provided by the Administrator consistent with Code Section 409A.  Under Section 3.02(a) of the Prior Plan, if a Member’s Grandfathered Supplemental Retirement Benefit is not paid in the “Regular Form” under the Qualified Plan, the benefit payable in an optional form shall be of equivalent actuarial value to the benefit otherwise payable in the Regular Form, determined using the same actuarial factors and assumptions then used to determine actuarial equivalence under the Qualified Plan.  Except as otherwise provided in Section 7.3, Grandfathered Supplemental Retirement Benefits to which a Member may be entitled, if any, shall be paid in accordance with the terms of the Prior Plan.  Under Section 3.02(a) of the Prior Plan, such benefit shall be paid in the same form as elected by the Member under the Qualified Plan; provided, however, that an election to receive a lump sum payment under the Plan must be filed at least twelve (12) calendar months prior to the Member’s retirement.

3.3                                  Adjustment of Non-Grandfathered Supplemental Retirement Benefits .  The amount of Non-Grandfathered Supplemental Retirement Benefit described in Section 3.1 above shall be calculated based upon the Member’s Qualified Plan Retirement Benefit determined as of the earlier of (a) the Member’s actual “Commencement Date” under the Qualified Plan, or (b) the Member’s Pension Commencement Date under this Plan (including the Pension Commencement Date of any Grandfathered Supplemental Benefit).  To the extent that the Member’s Commencement Date under the Qualified Plan is used as the calculation date, the Member’s
