                   Junior Subordinated Debt Security due 2036
                              of Service lstBancorp

         Service 1st Bancorp, a bank holding company incorporated in California
(the "Company"), for value received promises to pay to Wells Fargo Bank,
National Association, not in its individual capacity but solely as Institutional
Trustee for Service 1st Capital Trust I, a Delaware statutory trust (the
"Holder"), or registered assigns, the principal sum of Five Million One Hundred
Fifty-Five Thousand Dollars on October 7, 2036 and to pay interest on said
principal sum from August 17, 2006, or from the most recent interest payment
date (each such date, an "Interest Payment Date") to which interest has been
paid or duly provided for, quarterly (subject to deferral as set forth herein)
in arrears on January 7, April 7, July 7 and October 7 of each year commencing
October 7, 2006, at a variable per annum rate equal to LIBOR (as defined in the
Indenture) plus 1.60% (the "Interest Rate") (provided, however, that the
Interest Rate for any Interest Payment Period may not exceed the highest rate
permitted by New York law, as the same may be modified by United States law of
general applicability) until the principal hereof shall have become due and
payable, and on any overdue principal and (without duplication and to the extent
that payment of such interest is enforceable under applicable law) on any
overdue installment of interest at an annual rate equal to the Interest Rate in
effect for each such Extension Period compounded quarterly. The amount of
interest payable on any Interest Payment Date shall be computed on the basis of
a 360-day year and the actual number of days elapsed in the relevant interest
period. Notwithstanding anything to the contrary contained herein, if any
Interest Payment Date, other than on the Maturity Date, any Redemption Date or
the Special Redemption Date, falls on a day that is not a Business Day, then any
interest payable will be paid on, and such Interest Payment Date will be moved
to, the next succeeding Business Day, and additional interest will accrue for
each day that such payment is delayed as a result thereof. If the Maturity Date,
any Redemption Date or the Special Redemption Date falls on a day that is not a
Business Day, then the principal, premium, if any, and/or interest payable on
such date will be paid on the next succeeding Business Day, and no additional
interest will accrue (except that, if such Business Day falls in the next
calendar year, such payment will be made on the immediately preceding Business
Day). The interest installment so payable, and punctually paid or duly provided
for, on any Interest Payment Date will, as provided in the Indenture, be paid to
the Person in whose name this Debt Security (or one or more Predecessor
Securities, as defined in said Indenture) is registered at the close of business
on the regular record date for such interest installment, except that interest
and any Deferred Interest payable on the Maturity Date shall be paid to the
Person to whom principal is paid. Any such interest installment not punctually
paid or duly provided for shall forthwith cease to be payable to the registered
holders on such regular record date and may be paid to the Person in whose name
this Debt Security (or one or more Predecessor Debt Securities) is registered at
the close of business on a special record date to be fixed by the Trustee for
the payment of such defaulted interest, notice whereof shall be given to the
registered holders of the Debt Securities not less than 10 days prior to such
special record date, all as more fully provided in the Indenture. The principal
of and interest on this Debt Security shall be payable at the office or agency
of the Trustee (or other Paying Agent appointed by the Company) maintained for
that purpose in any coin or currency of the United States of America that at the
time of payment is legal tender for payment of public and private debts;

                                       170
<PAGE>

provided, however, that payment of interest may be made at the option of the
Company by check mailed to the registered holder at such address as shall appear
in the Debt Security Register or by wire transfer of immediately available funds
to an account appropriately designated by the holder hereof. Notwithstanding the
foregoing, so long as the holder of this Debt Security is the Institutional
Trustee, the payment of the principal of and premium, if any, and interest on
this Debt Security will be made in immediately available funds when due at such
place and to such account as may be designated by the Institutional Trustee. All
payments in respect of this Debt Security shall be payable in any coin or
currency of the United States of America that at the time of payment is legal
tender for payment of public and private debts.

         Upon submission of Notice (as defined in the Indenture) and so long as
no Event of Default pursuant to paragraphs (c), (e), (f) or (g) of Section 5.01
of the Indenture has occurred and is continuing, the Company shall have the
right, from time to time and without causing an Event of Default, to defer
payments of interest on the Debt Securities by extending the interest
distribution period on the Debt Securities at any time and from time to time
during the term of the Debt Securities, for up to 20 consecutive quarterly
periods (each such extended interest distribution period, an "Extension
Period"), during which Extension Period no interest shall be due and payable
(except any Additional Interest that may be due and payable). During any
Extension Period, interest will continue to accrue on the Debt Securities, and
interest on such accrued interest (such accrued interest and interest thereon
referred to herein as "Deferred Interest") will accrue at an annual rate equal
to the Interest Rate applicable during such Extension Period, compounded
quarterly from the date such Deferred Interest would have been payable were it
not for the Extension Period, to the extent permitted by law. No Extension
Period may end on a date other than an Interest Payment Date. At the end of any
such Extension Period the Company shall pay all Deferred Interest then accrued
and unpaid on the Debt Securities; provided, however, that no Extension Period
may extend beyond the Maturity Date, Redemption Date (to the extent redeemed) or
Special Redemption Date; and provided, further, however, during any such
Extension Period, the Company may not (i) declare or pay any dividends or
distributions on, or redeem, purchase, acquire, or make a liquidation payment
with respect to, any of the Company's capital stock or (ii) make any payment of
principal of or premium, if any, or interest on or repay, repurchase or redeem
any debt securities of the Company that rank pari passu in all respects with or
junior in interest to the Debt Securities or (iii) make any payment under any
guarantees of the Company that rank in all respects pari passu with or junior in
respect to the Capital Securities Guarantee (other than (a) repurchases,
redemptions or other acquisitions of shares of capital stock of the Company (A)
in connection with any employment contract, benefit plan or other similar
arrangement with or for the benefit of one or more employees, officers,
directors or consultants, (B) in connection with a dividend reinvestment or
stockholder stock purchase plan or (C) in connection with the issuance of
capital stock of the Company (or securities convertible into or exercisable for
such capital stock), as consideration in an acquisition transaction entered into
prior to the applicable Extension Period, (b) as a result of any exchange,
reclassification, combination or conversion of any class or series of the
Company's capital stock (or any capital stock of a subsidiary of the Company)
for any class or series of the Company's capital stock or of any class or series
of the Company's indebtedness for any class or series of the Company's capital
stock, (c) the purchase of fractional interests in shares of the Company's
capital stock pursuant to the conversion or exchange provisions of such capital
stock or the security being converted or exchanged, (d) any declaration of a
dividend in connection with any stockholder's rights plan, or the issuance

                                       171
<PAGE>

of rights, stock or other property under any stockholder's rights plan, or the
redemption or repurchase of rights pursuant thereto, or (e) any dividend in the
form of stock, warrants, options or other rights where the dividend stock or the
stock issuable upon exercise of such warrants, options or other rights is the
same stock as that on which the dividend is being paid or ranks part passu with
or junior to such stock). Prior to the termination of any Extension Period, the
Company may further extend such period, provided, that such period together with
all such previous and further consecutive extensions thereof shall not exceed 20
consecutive quarterly periods, or extend beyond the Maturity Date, Redemption
Date (to the extent redeemed) or Special Redemption Date. Upon the termination
of any Extension Period and upon the payment of all Deferred Interest, the
Company may commence a new Extension Period, subject to the foregoing
requirements. No interest or Deferred Interest shall be due and payable during
an Extension Period, except at the end thereof, but Deferred Interest shall
accrue upon each installment of interest that would otherwise have been due and
payable during such Extension Period until such installment is paid. The Company
must give the Trustee notice of its election to begin or extend an Extension
Period ("Notice") not later than the related regular record date for the
relevant Interest Payment Date. The Notice shall describe, in reasonable detail,
why the Company has elected to begin an Extension Period. The Notice shall
acknowledge and affirm the Company's understanding that it is prohibited from
issuing dividends and other distributions during the Extension Period. Upon
receipt of the Notice, an Initial Purchaser shall have the right, at its sole
discretion, to disclose to the Securityholders the name of the Company, the fact
that the Company has elected to begin an Extension Period and other information
that such Initial Purchaser, at its sole discretion, deems relevant to the
Company's election to begin an Extension Period. The Trustee shall give notice
of the Company's election to begin a new Extension Period to the
Securityholders.

         The indebtedness evidenced by this Debt Security is, to the extent
provided in the Indenture, subordinate and junior in right of payment to the
prior payment in full of all Senior Indebtedness, and this Debt Security is
issued subject to the provisions of the Indenture with respect thereto. Each
holder of this Debt Security, by accepting the same, (a) agrees to and shall be
bound by such provisions, (b) authorizes and directs the Trustee on such
holder's behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate the subordination so provided and (c) appoints the
Trustee such holder's attorney-in-fact for any and all such purposes. Each
holder hereof, by such holder's acceptance hereof, hereby waives all notice of
the acceptance of the subordination provisions contained herein and in the
Indenture by each holder of Senior Indebtedness, whether now outstanding or
hereafter incurred, and waives reliance by each such holder upon said
provisions.

         The Company waives diligence, presentment, demand for payment, notice
of nonpayment, notice of protest, and all other demands and notices.

         This Debt Security shall not be entitled to any benefit under the
Indenture hereinafter referred to and shall not be valid or become obligatory
for any purpose until the certificate of authentication hereon shall have been
signed by or on behalf of the Trustee.

         The provisions of this Debt Security are continued on the reverse side
hereof and such continued provisions shall for all purposes have the same effect
as though fully set forth at this place.
