whichever is less, in immediately available funds at BANK OF AMERICA NATIONAL

         This note is one of the notes issued pursuant to, and is entitled to
the benefits of, that certain Amended and Restated Credit Agreement, dated as
of August 7, 1996 (as the same may be amended, modified or restated from time

(the "U.S. Agent"), Issuing Bank and Swing Loan Bank, BANK OF AMERICA CANADA,

defined herein shall have the meaning assigned to them in the Credit Agreement.

prepayment hereof, the acceleration of the maturity hereof and to the effect
that no provision of the Credit Agreement or this Note shall require the
payment or permit the charging or collection of interest in an amount in excess
of the highest non-usurious or non-criminal amount permitted by applicable law.

         It is contemplated that by reason of prepayments hereon prior to the
Revolving Termination Date, there may be times when no indebtedness is owing
hereunder prior to such date, but notwithstanding such occurrence this note
shall be in full force and effect as to the Revolving Loans made pursuant to
the Credit Agreement subsequent to each such occurrence.
<PAGE>   2
         All Revolving Loans made by the Bank pursuant to the Credit Agreement
and all payments of the principal thereof shall be endorsed by the holder of
this Revolving Note on the schedule annexed hereto (including any additional
pages such holder may add to such schedule), which endorsement shall constitute
prima facie evidence of the accuracy of the information so endorsed; provided,
however, that the failure of the holder of this Revolving Note to insert any
date or amount or other information on such schedule shall not in any manner
affect the obligation of the Borrower or the other Borrowers to repay any
Revolving Loans in accordance with the terms of the Credit Agreement.

         The Borrower and any and all sureties, guarantors and endorsers of
this Revolving Note and all other parties now or hereafter liable hereon,
severally waive, except as otherwise provided in the Credit Agreement or in any
other of the Loan Documents, grace, demand, presentment for payment, protest,
notice of any kind (including, but not limited to, notice of dishonor, notice
of protest, notice of intention to accelerate and notice of acceleration) and
diligence in collecting and bringing suit against any party hereto, and agree
(i) to all extensions and partial payments, with or without notice, before or
after maturity, (ii) to any substitution, exchange or release of any security
now or hereafter given for this Revolving Note, (iii) to the release of any
party primarily or secondarily liable hereon, and (iv) that it will not be
necessary for the Bank, in order to enforce payment of this Revolving Note, to
first institute or exhaust the Bank's remedies against the Borrower or any
other party liable therefor or against any security for this Revolving Note.

         This Revolving Note may not be changed, modified or terminated orally,
but only by an agreement in writing signed by the party charged.  If any term
or provision of this Revolving Note shall be held invalid, illegal or
unenforceable, the validity of all other terms and provisions herein shall in
no way be affected thereby.

         IN THE EVENT OF ANY LITIGATION WITH RESPECT TO THIS REVOLVING NOTE,
THE BORROWER WAIVES THE RIGHT TO A TRIAL BY JURY AND THE DEFENSES OF FORUM NON
CONVENIENS AND IMPROPER VENUE.  THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK AND SHALL BE BINDING UPON THE
SUCCESSORS AND ASSIGNS OF BORROWER AND INURE TO THE BENEFIT OF THE BANK AND ITS
SUCCESSORS AND ASSIGNS (INCLUDING PARTICIPANTS IN ACCORDANCE WITH THE TERMS OF
THE CREDIT AGREEMENT).

         This note is one of the notes issued pursuant to, and is entitled to
the benefits of, that certain Amended and Restated Credit Agreement, dated as
of August 7, 1996 (as the same may be amended, modified or restated from time

BJ SERVICE INTERNATIONAL, INC., a Delaware corporation, BJ SERVICES COMPANY

defined herein shall have the meaning assigned to them in the Credit Agreement.
Reference is made to the Credit Agreement for, inter alia, provisions for the
prepayment hereof, the acceleration of the maturity hereof and to the effect
that no provision of the Credit Agreement or this Note shall require the
payment or permit the charging or collection of interest in an amount in excess
of the highest non-usurious or non-criminal amount permitted by applicable law.

         All Swing Loans made by the Bank pursuant to the Credit Agreement and
all payments of the principal thereof shall be endorsed by the holder of this
Swing Loan Note on the schedule annexed hereto (including any additional pages
such holder may add to such schedule), which endorsement shall constitute prima
facie evidence of the accuracy of the information so endorsed;
<PAGE>   12
provided, however, that the failure of the holder of this Swing Loan Note to
insert any date or amount or other information on such schedule shall not in
any manner affect the obligation of the Borrower or any other Borrowers to
repay any Swing Loans in accordance with the terms of the Credit Agreement.

         The Borrower and any and all sureties, guarantors and endorsers of
this Swing Loan Note and all other parties now or hereafter liable hereon,
severally waive, except as otherwise provided in the Credit Agreement or in any
other of the Loan Documents, grace, demand, presentment for payment, protest,
notice of any kind (including, but not limited to, notice of dishonor, notice
of protest, notice of intention to accelerate and notice of acceleration) and
diligence in collecting and bringing suit against any party hereto, and agree
(i) to all extensions and partial payments, with or without notice, before or
after maturity, (ii) to any substitution, exchange or release of any security
now or hereafter given for this Swing Loan Note, (iii) to the release of any
party primarily or secondarily liable hereon and (iv) that it will not be
necessary for the Bank, in order to enforce payment of this Swing Loan Note, to
first institute or exhaust the Bank's remedies against the Borrower or any
other party liable therefor or against any security for this Swing Loan Note.

         This Swing Loan Note may not be changed, modified, or terminated
orally, but only by an agreement in writing signed by the party to be charged.
If any term or provision of this Swing Loan Note shall be held invalid, illegal
or unenforceable, the validity of all other terms and provisions herein shall
in no way be affected thereby.

         IN THE EVENT OF ANY LITIGATION WITH RESPECT TO THIS SWING LOAN NOTE,
THE BORROWER WAIVES THE RIGHT TO A TRIAL BY JURY AND THE DEFENSES OF FORUM NON
CONVENIENS AND IMPROPER VENUE.  THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK AND SHALL BE BINDING UPON THE
SUCCESSORS AND ASSIGNS OF BORROWERS AND INURE TO THE BENEFIT OF THE BANK AND
ITS SUCCESSORS AND ASSIGNS (INCLUDING PARTICIPANTS IN ACCORDANCE WITH THE TERMS
OF THE CREDIT AGREEMENT).

         IN WITNESS WHEREOF, the Borrower has executed and delivered this Swing
Loan Note on the date first above written.

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