(i)           “Separation
from Service” means a termination of the Executive’s services (whether as an
employee or as an independent contractor) to the Bank.  Whether a
Separation from Service has occurred shall be determined in accordance with the
requirements of Section 409A of the Code based on whether the facts and
circumstances indicate that the Bank and the Participant reasonably anticipated
that no further services would be performed after a certain date or that the
level of bona fide services the Executive would perform after such date (whether
as an employee or as an independent contractor) would permanently decrease to no
more than twenty percent (20%) of the average level of bona fide services
performed (whether as an employee or an independent contractor) over the
immediately preceding thirty-six (36) month period.





2.
            Payments to
      Executive.

to the Executive annually, a benefit payable in the Normal Form in equal monthly
installments commencing on the first day of the month next following the

            5011
            5512

            8017
            8518
            100





Notwithstanding
the foregoing, the Executive shall become fully vested immediately upon his
death prior to a Separation from Service, a Change in Control or upon any
involuntary termination of his employment by the Bank other than for
Cause.





(c)           If
the Accrued Benefit is payable before the Executive’s 65th
birthday, the Accrued Benefit shall be reduced by 2.5% for each year benefits
commence before the Executive’s 65th
birthday.





(d)           In
lieu of the Normal Form provided by the foregoing provisions of this Paragraph
2, with the consent of the Bank, the Executive may elect an optional form of
payment which is the Actuarial Equivalent of the Normal Form to which the
Executive is entitled, which optional form of payment may be any optional form
provided under the SBERA Plan, including a lump sum.  (The Executive
elected a lump sum payment prior to January 1, 2007.  On or after
January 1, 2009, if the Executive wishes to change his payment election as to
the form of payment, the Executive may do so by completing a payment election
form approved by the Board of Directors, provided that any such election (i)
must be made prior to the Executive’s Separation from Service, (ii) must be made
at least 12 months before the date on which any benefit payments are scheduled
to commence, (iii) shall not take effect until at least 12 months after the date
the election is made, and (iv) for payments to be made other than upon death or
disability, must provide an additional deferral period of at least five years
from the date such payment would otherwise have been made (or in the case of any
installment payments treated as a single payment, five years from the date the
first amount was scheduled to be paid).  For purposes of this
Agreement and clause (iv) above, all installment payments under this Agreement
shall be treated as a single payment.  On or before December 31,
,2008, if the Executive wishes to change his payment election as to the form of
payment, the Participant may do so by completing a payment election form,
provided that any such election (i) must be made prior to the Executive’s
Separation from Service, (ii) shall not take effect before the date that is 12
months after the date the election is made, and (iii) made in 2008 cannot apply
to amounts that would otherwise be payable in 2008 and may not cause an amount
to be paid in 2008 that would otherwise be paid in a later year.  A
lump sum payment shall be made within sixty (60) days following the date the
Participant becomes entitled to receive a benefit under the
Plan.

(e)           Notwithstanding
anything to the contrary set forth herein, in no event shall the Executive be
entitled to receive any benefits under this Agreement if he is terminated by the
Board of Directors of the Bank for Cause.  A determination of whether
the Executive’s employment is terminated for Cause shall be made at a meeting of
the Board of Directors called and held for such purpose, at which the Board of
Directors makes a finding that in their good faith opinion an event set forth in
Section 1(c) of this Agreement has occurred and specifying the particulars
thereof in detail.





(f)           Notwithstanding
any provision of this Agreement to the contrary, if the Executive is considered
a Specified Employee at Separation from Service under such procedures as
established by the Bank in accordance with Section 409A of the Code, benefit
distributions that are made upon Separation from Service may not commence
earlier than six (6) months after the date of such Separation from
Service.  Therefore, in the event this Section 2(f) is applicable to
the Executive, any distribution which would otherwise be paid to the Executive
within the first six months following the Separation from Service shall be
accumulated and paid (with interest calculated at the Prime Rate reported in the
Wall Street Journal as of the date the benefit first became payable) to the
Executive in a lump sum on the first day of the seventh month following the
Separation from Service.  All subsequent distributions shall be paid
in the manner specified under this Section 2 of the Plan with respect to the
applicable benefit.  A Specified Employee means a key employee (as
defined in Section 416(i) of the Code without regard to paragraph 5 thereof) of
the Bank if any stock of the Bank is publicly traded on an established
securities market or otherwise or if the Bank is the subsidiary of a
publicly-traded holding company.





3.
            Death of the
      Executive.





(a)           If
the Executive dies prior to the commencement of the payment of benefits under
this Agreement, the Bank will pay to the Executive’s surviving spouse a benefit
payable for her life assuming that the Executive had retired the day before his
death and had elected to receive his Accrued Benefit (as reduced by 2.5% each
year and pro-rated for a partial year if the death occurs before the Executive’s
65th
birthday and before the Executive has completed twenty-five (25) years of
service, as provided for in Section 2(c) of this Agreement) in the form of a
joint and 100% spousal survivor annuity.  The surviving spouse may
elect to receive the death benefit in a lump sum or any other form on an
Actuarially Equivalent basis.





(b)           If
the Executive dies following the commencement of the payment of benefits under
this Agreement, death benefits, if any, will be determined pursuant to the form
of benefit payment in effect at the time of death and paid to the beneficiary
designated by the Executive.





4.
            Disability
      Benefits.





If the
Executive becomes permanently and totally disabled, as determined by a physician
mutually acceptable to the Bank and the Executive, from any cause while in the
employ of the Bank and prior to the commencement of payments under Paragraph 2
above, the Executive shall be entitled to receive the Accrued Benefit that would
be payable to the Executive pursuant to Paragraph 2 above if the Executive had
terminated his employment on the date of his disability with twenty (20) years
of service.  Disability payments may be subject to a six (6) month
waiting period, in which case during such time the Bank shall continue to pay
the Executive his base salary.  For purposes of this Agreement,
“Disabilities” shall mean the Executive is unable to engage in any substantial
activity by reason of any medically determinable physical or mental impairment
that can be expected to result in death or can be expected to last for a
continuous period of not less than twelve (12) months.

      Procedure.





(a)           In

right to a benefit under this Agreement which has not been received, the
Claimant must file a claim for such benefit with the Bank on forms provided by
the Bank.  The Bank shall render its decision on the claim within 90
days after its receipt of the claim.  If special circumstances apply,
the 90-day period may be extended by an additional 90 days; provided, written
notice of the extension is provided to the Claimant during the initial 90-day
period and such notice indicates the special circumstances requiring an
extension of time and the date by which the Bank expects to render its decision
on the claim.  If the Bank wholly or partially denies the claim, the
Bank shall provide written notice to the Claimant within the time limitations of
the immediately preceding paragraph.  Such notice shall set
forth:





(i)           the
specific reasons for the denial of the claim;





(ii)           specific

the claim.





(b)           A
Claimant whose application for benefits is denied may request a full and fair
review of the decision denying the claim by filing, in accordance with such
procedures as the Bank may establish, a written appeal which sets forth the
documents, records and other information relating to the claim within 60 days
after receipt of the notice of the denial from the Bank.  In
connection with such appeal and upon request by the Claimant, a Claimant may
review (or receive free copies of) all documents, records or other information
relevant to the Claimant’s claim for benefit, all in accordance with such
procedures as the Bank may establish.  If a Claimant fails to file an
appeal within such 60-day period, he shall have no further right to
appeal.





(c)           A
decision on the appeal by the Bank shall include a review by the Bank that takes
into account all comments, documents, records and other information submitted by
the Claimant relating to the claim, without regard to whether such information
was submitted or considered in the initial claim determination.  The
Bank shall render its decision on the appeal not later than 60 days after the
receipt by the Bank of the appeal.  If special circumstances apply,
the 60-day period may be extended by an additional 60 days; provided, written
notice of the extension is provided to the Claimant during the initial 60-day
period and such notice indicates the special circumstances requiring an
extension of time and the date by which the Bank expects to render its decision
on the claim on appeal.  If the Bank wholly or partly denies the claim
on appeal, the Bank shall provide written notice to the Claimant within the time
limitations of the immediately preceding paragraph.  Such notice shall
set forth:

statement of the Claimant’s right to bring a civil action under Section 502(a)
of ERISA.





6.
            Violation of
      Agreement.





In the
event of the violation of any of any material terms of the Agreement by the
Executive, the Bank, in addition to any other rights which it may have, shall be
relieved of the liability to make any further payments under the Agreement to,
or on behalf of, the Executive so long as such violation continues, and shall
have the right to specific enforcement of the Agreement by proceedings in
equity.

            Nonassignable
      Rights.

otherwise provided by the Agreement, neither the Executive nor his surviving
spouse shall have any right to commute, sell, assign, transfer or otherwise
convey the right to receive any payments hereunder, which payments and the right
thereto are expressly declared to be nonassignable and
nontransferable.





8.
            Independence of
      Agreement.





The
benefits payable under the Agreement shall be independent of, and in addition
to, any employment agreement that may exist from time to time between the
parties hereto, or any other compensation payable by the Bank to the Executive,
whether as salary, bonus or otherwise.  The Agreement shall not be
deemed to constitute a contract of employment between the parties hereto, and no
provision hereof shall restrict the right of the Bank to discharge the Executive
for adequate cause, or restrict the right of the Executive to terminate his
employment.





9.
            General Obligation of
      the Bank.





The
benefits provided under the Agreement constitute a mere promise by the Bank to
make payments in the future, and the rights of the Executive hereunder shall be
those of a general unsecured creditor of the Bank.  Nothing contained
herein shall be construed to create a trust of any kind or to render the Bank a
fiduciary with respect to the Executive.  The Bank shall not be
required to maintain any fund or segregate any amount or in any other way
currently fund the future payment of any benefit provided under the Agreement,
and nothing contained herein shall be construed to give the Executive or any
other person any right to any specific assets of the Bank or of any other
person.
