     (b)  Notwithstanding anything to the contrary contained in this Loan
Agreement or the Promissory Note, the Borrower shall not be obligated to make
any payment, repayment or prepayment on the Promissory Note if doing so would
cause the ESOP to cease to be an employee stock ownership plan within the
meaning of section 4975(e)(7) of the Code or qualified under section 401(a) of
the Code or cause the Borrower to cease to be a tax exempt trust under section
501(a) of the Code or if such act or failure to act would cause the Borrower to
engage in any "prohibited transaction" as such term is defined in the section
4975(c) of the Code and the regulations promulgated thereunder which is not
exempted by section 4975(c)(2) or (d) of the Code and the regulations
promulgated thereunder or in section 406 of ERISA and the regulations
promulgated thereunder which is not exempted by section 408(b) of ERISA and the
regulations promulgated thereunder; provided, however, that in each case, the
Borrower, may act or refrain from acting pursuant to this section 2.6(b) on the
basis of an opinion of counsel, and any opinion of such counsel. The Borrower
may consult with counsel, and any opinion of such counsel shall be full and
complete authorization and protection in respect of any action taken or suffered
or omitted by it hereunder in good faith and in accordance with such opinion of
counsel.  Nothing contained in this section 2.6(b) shall be construed as
imposing a duty on the Borrower to consult with counsel.  Any obligation of the
Borrower to make any payment, repayment or prepayment on the Promissory Note or
refrain from taking any other act hereunder or under the Promissory Note which
is excused pursuant to this section 2.6(b) shall be considered a binding
obligation of the Borrower, or both, as the case may be, for the purposes of
determining whether a Default or Event of Default has occurred hereunder or

                                       4

under the Promissory Note and nothing in this section 2.6(b) shall be construed
as providing a defense to any remedies otherwise available upon a Default or an
Event of Default hereunder (other than the remedy of specific performance).

                    -----------------------

     Agreement.

     (b)  The Lender shall release from encumbrance under the Pledge Agreement

                    -----------------------------------

     (a)  The Lender shall maintain a Register providing for the registration of
the Principal Amount and any stated interest and of transfer and exchange of the
Promissory Note.  Transfer of the Promissory Note may be effected only by the
surrender of the old instrument and either the reissuance by the Borrower of the
old instrument to the new holder or the issuance by the Borrower of a new
instrument to the new holder.  The old Promissory Note so surrendered shall be
canceled by the Lender and returned to the Borrower after such cancellation.

     (b)  Any new Promissory Note issued pursuant to section 2.9(a) shall carry
the same rights to interest (unpaid and to accrue) carried by the Promissory
Note so transferred or exchanged so that there will not be any loss or gain of
interest on the note surrender.  Such new Promissory Note shall be subject to
all of the provisions and entitled to all of the benefits of this Agreement.
Prior to due presentment for registration or transfer, the Borrower may deem and
treat the registered holder of any Promissory Note as the holder thereof for
purposes of payment and other purposes.  A notation

represents, warrants, and covenants to the Pledgee as follows:
<PAGE>

rights it may have under the Loan Agreement, the Promissory Note, and this
Pledge Agreement, or by virtue of any other instrument, (i) the Pledgee may
exercise, with respect to the Eligible Collateral, from time to time, any rights
and remedies available to it under the Uniform Commercial Code as in effect from
time to time in the State of Delaware or otherwise available to it and (ii) the
Pledgee shall have the right, for and in the name, place and stead of the

before such disposition. Subject to section 13 below, any proceeds of any
disposition of Eligible Collateral may be applied by the Pledgee to the payment
of expenses in connection with the Eligible Collateral, including, without
limitation, reasonable attorneys's fees and legal expenses, and any balance of
such proceeds may be applied by the Pledgee toward the payment of such of the
Liabilities as are in Default, and in such order of application, as the Pledgee
may from time to time elect.  No action of the Pledgee permitted hereunder shall
impair or affect its rights in and to the Eligible Collateral.  All rights and
remedies of the Pledgee expressed hereunder are in addition to all other rights
and remedies possessed by it, including, without limitation, those contained in
the documents referred to in the definition of Liability in section 1 hereof.

Event of Default shall have occurred, the Pledgee is hereby authorized to comply
with any limitation or restriction in connection with such sale as it may be
advised by counsel is necessary in order to avoid violation of applicable law
(including, without limitation, compliance with such procedures as may restrict

prospective bidders or purchasers to persons who will represent and agree that
they are purchasing for their own account

for investment and not with a view to the distribution or resale of such
Eligible Collateral), or in order to obtain such required approval of the sale
or of the purchase by any governmental regulatory authority or official, and the
Pledgor further agrees that such compliance shall not result in such sale's
being considered or deemed not to have been made in a commercially reasonable
manner, nor shall the Pledgee be liable or accountable to the Pledgor for any
discount allowed by reason of the fact that such Eligible Collateral is sold in
compliance with any such limitation or restriction.

     Section 7.   Payment in Full.  Upon the payment in full of all outstanding
                  ---------------
Liabilities, this Pledge Agreement shall terminate and the Pledgee shall
forthwith assign, transfer and deliver to the Pledgor, against receipt and
without recourse to the Pledgee, all Collateral then held by the Pledgee
pursuant to the Pledge Agreement.

     Section 8.   No Waiver.  No failure or delay in the part of the Pledgee in
                  ---------
exercising any right or remedy hereunder or under any other document which
confers or grants any rights in the Pledgee in respect of the Liabilities shall
operate as a waiver thereof nor shall any single or partial exercise of any such
rights or remedy preclude any other or further exercise thereof or the exercise
of any other right or remedy of the Pledgee.

     Section 9.   Binding Effect; No Assignment or Delegation.  This Pledge
                  -------------------------------------------
Agreement shall be binding upon and inure to the benefit of the Pledgor, the
Pledgee and their respective successors and assigns, except that the Pledgor may
not assign or transfer it rights hereunder without the prior written consent of
the Pledgee (which consent shall not unreasonably be withheld).  Each duty or
obligation of the Pledgor to the Pledgee pursuant to the provisions of this
Pledge Agreement shall be performed in favor of any person or entity designated
by the Pledgee, and any duty or obligation of the Pledgee to the Pledgor may be
performed by any other person or entity designated by the Pledgee.

PRINCIPAL


     FOR VALUE RECEIVED, the undersigned, the CITIZENS FIRST SAVINGS BANK
EMPLOYEE STOCK OWNERSHIP PLAN TRUST ("Borrower"), hereby promises to pay to the
order of CITIZENS FIRST BANCORP, INC. ("Lender") _____________  payable in
accordance with the Loan Agreement made and entered into between the Borrower
and the Lender of even date herewith ("Loan Agreement") pursuant to which this
Promissory Note is issued.

     The Principal Amount of this Promissory Note shall be payable in accordance
with the schedule attached hereto ("Schedule I").

     This Promissory Note shall bear interest at the rate per annum set for or
established under the Loan Agreement, such interest to be payable in accordance
with Schedule I.

     Anything herein to the contrary notwithstanding, the obligation of the
Borrower to make payments of interest shall be subject to the limitation that
payments of interest shall not be required to be made to the Lender to the
extent that the Lender's receipt thereof would not be permissible under the law
or laws applicable to the Lender limiting rates on interest which may be charged
or collected by the Lender.  Any such payments on interest which are not made as
a result of the limitation referred to in the preceding sentence shall be made
by the Borrower to the Lender on the earliest interest payment date or dates on
which the receipt thereof would be permissible under the laws applicable to the
Lender limiting rates of interest which may be charges or collected by the
Lender.  Such deferred interest shall not bear interest.

     Payments of both principal and interest on this Promissory Note are to be
made at the principal office of the Lender or such other place as the holder
hereof shall designate to the Borrower in writing, in lawful money of the United
States of America in immediately available funds.

     Failure to make any payments of principal on this Promissory Note when due,
or failure to make any payment of interest on this Promissory Note not later
than five (5) Business Days after the date when due, shall constitute a default
hereunder, whereupon the principal amount of accrued interest on this Promissory
Note shall immediately become due and payable in accordance with the terms of
the Loan Agreement.
<PAGE>

     This Promissory Note is secured by a Pledge Agreement between the Borrower
and the Lender of even date herewith and is entitled to the benefits thereof.
