                            HOUSEHOLD INTERNATIONAL

                    NON-QUALIFIED DEFERRED COMPENSATION PLAN
                          FOR RESTRICTED STOCK RIGHTS

         Section 1. Purpose. The purpose of this Plan is to provide certain
         ---------  -------
executives of Household International, Inc. (the "Company") and certain of its
direct and indirect subsidiaries (the Company and such subsidiaries being
referred to as the "Employers") the opportunity to defer receipt of compensation
and provide for future savings of compensation earned in connection with the
vesting of Household Restricted Stock Rights. The provision of such an
opportunity is designed to aid the Company in attracting and retaining as
executives persons whose abilities, experience and judgment can contribute to
the well-being of the Company.

         Section 2. Name, Effective Date. The effective date of this plan known
         ---------  --------------------
as the Household International Non-Qualified Deferred Compensation Plan for
Restricted Stock Rights (the "Plan") is September 11, 2001.

         Section 3. Eligibility. Any executive of the Employers who is a
         ---------  -----------
participant in the 1998 Key Executive Bonus Plan and has outstanding Restricted
Stock Rights for Household International, Inc. Common Stock, $1.00 par value
("Household stock") is eligible to participate in this Plan.

         Section 4. Deferred Compensation Account. An unfunded deferred
         ---------  -----------------------------
compensation account shall be established for each person who elects to
participate in the Plan.

         Section 5. Amount of Deferral. In the calendar year prior to the
         ---------  ------------------
scheduled vesting of Household Restricted Stock Rights on a date at least six
months prior to the date the participant's Restricted Stock Rights are scheduled
to vest, the participant can make an irrevocable election to defer the right to
receive all or a portion of the stock that would otherwise be paid to the
participant upon the scheduled vesting of the Restricted Stock Rights. The
Household stock as to which an election is made will be credited to the
participant's deferred compensation account on the date such stock would
otherwise have been initially vested.

         Section 6. Election of Deferral. An election to defer the right to
         ---------  --------------------
receive stock under this Plan shall be made on forms provided by the
Compensation Committee of the Board of Directors

<PAGE>

of the Company (the "Committee") for that purpose and shall be effective on the
date indicated, but not before the date filed with the Committee.

         If a participant has failed to select a deferred distribution date for
a deferral or if he terminates employment before such deferred distribution
date, then distribution of such deferred compensation account will be made as
soon as practicable in the calendar year following the date of the participant's
termination of employment. The earliest deferred distribution date specified by
the participant for any deferral under this Plan must be at least two years
after the calendar year in which the vesting of Restricted Stock Rights
otherwise would have occurred. The election shall be irrevocable upon receipt by
the Committee.

         Section 7. Hypothetical Investment. Each deferred compensation account
         ---------  -----------------------
will be credited with hypothetical shares of Household stock on the date on
which the Household Restricted Stock Rights otherwise would have vested. During
the deferral period, the deferred compensation account will be credited on each
dividend payment date for the Company's Common Stock with additional
hypothetical shares of Household stock determined by dividing the aggregate cash
dividend which would have been paid if the existing Household stock were actual
shares of the Company's Common stock by the fair market value of the Company's
Common Stock as of the dividend payment date, computed to four decimal places.
For purposes of the Plan, the "fair market value" of one share of the Company's
Common Stock shall be the average of the high and low sale prices for a share of
such Common Stock for the respective determination date. There is no guarantee a
participant's deferred compensation account will increase in value; the account
may decrease in value based on the performance of Household stock.

         Section 8. Payment of Deferral. If a participant elected to defer any
         ---------  -------------------
year's compensation under this Plan to a specific date other than his or her
termination of employment, the value of such year's deferred compensation will
be payable in stock with only fractional shares paid in cash on the date
specified unless it is paid earlier due to termination of employment. The value
of a participant's deferred compensation account will be payable in stock with
only fractional shares paid in cash as soon as practicable following the end of
the year in which a participant terminates employment unless an earlier date is
specified by the participant in his deferral

                                       2

<PAGE>

election. All deferred amounts to be paid to a participant pursuant to the Plan
are to be paid in shares of Household stock with the value of such shares being
the fair market value of an equal number of shares of Household stock on the
date of payment.

         In the event that the participant becomes totally disabled, the
Committee, in its absolute discretion, may distribute all or a portion of the
participant's deferred compensation account according to a revised payment
schedule but it must still be paid in stock.

         Section 9. Withholding. Subject to the following sentence, there shall
         ---------  -----------
be deducted from all deferrals and payments under this Plan the amount of any
taxes required to be withheld by any federal, state or local government unless
these amounts are paid in cash by the participant. However, for any taxes
required to be withheld by any federal, state or local government in connection
with a deferral, these amounts must be paid in cash immediately after the
vesting date and not by reducing the shares otherwise credited to the
participant's account. The participants and their beneficiaries, distributees,
and personal representatives will bear any and all federal, foreign, state,
local or other income or other taxes imposed on amounts deferred or paid under
this Plan.

         Section 10. Designation of Beneficiary. A participant may designate a
         ----------  --------------------------
beneficiary or beneficiaries which shall be effective upon filing written notice
with the Committee on the form provided by the Committee for that purpose. If no
beneficiary is designated, the beneficiary will be the participant's estate. If
more than one beneficiary statement has been filed, the beneficiary or
beneficiaries designated in the statement bearing the most recent date will be
deemed the valid beneficiary or beneficiaries.

         Section 11. Death of Participant or Beneficiary. In the event of a
         ----------  -----------------------------------
participant's death before he has received the full value of his deferred
compensation account, the then current value of the participant's deferred
compensation account shall be determined and such amount shall be paid to the
beneficiary or beneficiaries of the deceased participant as soon as practicable
thereafter in stock with only fractional shares paid in cash. If no designated
beneficiary has been named or survives the participant, the beneficiary will be
the participant's estate.

         Section 12. Participant's Rights Unsecured. The right of any
         ----------  ------------------------------
participant or beneficiary to receive payment under the provisions of the Plan
shall be an unsecured claim against the general

                                       3

<PAGE>

assets of the Company, and any successor company in the event of a merger,
consolidation, reorganization or any other event which causes the Company's
assets or business to be acquired by another company. No provisions contained in
the Plan shall be construed to give any participant or beneficiary at any time a
security interest in the deferred compensation account or any other assets of
the Company. Upon deferral under this Plan, a participant gives up his right to
receive stock that otherwise would have been issued as a consequence of vesting
of Restricted Stock Rights and receives, instead, the contractual right to an
unfunded deferred compensation account equal in value to the value of the stock
that otherwise would have been received.

         Section 13. Statement of Account. Statements will be sent to
         ----------  --------------------
participants following the end of each year as to the value of their deferred
compensation accounts as of December 31st of such year.

         Section 14. Assignability. No right to receive payments hereunder shall
         ----------  -------------
be transferable or assignable by a participant or a beneficiary.

         Section 15. Administration of the Plan. The Plan shall be administered
         ----------  --------------------------
by the Committee. The Committee shall conclusively interpret the provisions of
the Plan, decide all claims, and shall make all determinations under the Plan.
The Committee shall act by vote or written consent of a majority of its members.
The Committee may authorize the appointment of an agent to perform recordkeeping
and other administrative duties with respect to the Plan.

         Section 16. Amendment or Termination of Plan. This Plan may at any time
         ----------  --------------------------------
or from time to time be amended, modified or terminated by the Committee. No
amendment, modification or termination shall, without the consent of a
participant, adversely affect such participant's accruals on his prior
elections. Rights accrued prior to termination of the Plan will not be canceled
by termination of the Plan.

         Section 17. Governing Law. This Agreement shall be governed by and
         ----------  -------------
construed in accordance with the laws of the State of Illinois.

         Section 18. Payment of Certain Costs of the Participant. If a dispute
         ----------  -------------------------------------------
arises regarding the interpretation or enforcement of this Plan and the
participant (or, in the event of his death, his beneficiary) obtains a final
judgment in his favor from a court of competent jurisdiction from which no
appeal may be taken, whether because the time to do so has expired or otherwise,
or his

                                       4

<PAGE>

claim is settled by the Company prior to the rendering of such a judgment, all
reasonable legal and other professional fees and expenses incurred by the
participant in contesting or disputing any such claim or in seeking to obtain or
enforce any right or benefit provided for in this Plan or in otherwise pursuing
his claim will be promptly paid by the Company with interest thereon at the
highest Illinois statutory rate for interest on judgments against private
parties from the date of payment thereof by the participant to the date of
reimbursement to him by the Company.

         Section 19. Securities Law. With respect to participants subject to
         ----------  --------------
Section 16 of the Exchange Act, transactions under this Plan are intended to
comply with all applicable provisions of Rule 16b-3 or its successor under the
Securities Exchange Act of 1934. To the extent any provision of the Plan or
action by the Committee or its designee fails to so comply, it shall be deemed
null and void.

         Section 20. Change in Control. A "Change in Control " shall be deemed
         ----------  -----------------
to have occurred if:

         (1)   Any "person" (as defined in Section 13(d) and 14(d) of the
               Securities Exchange Act of 1934, as amended (the "Exchange
               Act")), excluding for this purpose the Company or any subsidiary
               of the Company, or any employee benefit plan of the Company, or
               any subsidiary of the Company, or any person or entity organized,
               appointed or established by the Company for or pursuant to the
               terms of such plan which acquires beneficial ownership of voting
               securities of the Company, is or becomes the "beneficial owner"
               (as defined in Rule 13d-3 under the Exchange Act) directly or
               indirectly of securities of the Company representing twenty
               percent (20%) or more of the combined voting power of the
               Company's then outstanding securities; provided, however, that no
               Change in Control shall be deemed to have occurred as the result
               of an acquisition of securities of the Company by the Company
               which, by reducing the number of voting securities outstanding,
               increases the direct or indirect beneficial ownership interest of
               any person to twenty percent (20%) or more of the combined voting
               power of the Company's then outstanding securities, but any
               subsequent increase in the direct or indirect beneficial
               ownership interest of such a person in the Company shall be
               deemed a Change in Control; and provided further that if the

                                       5

<PAGE>

               Board of Directors of the Company determines in good faith that a
               person who has become the beneficial owner directly or indirectly
               of securities of the Company representing twenty percent (20%) or
               more of the combined voting power of the Company's then
               outstanding securities has inadvertently reached that level of
               ownership interest, and if such person divests as promptly as
               practicable a sufficient amount of securities of the Company so
               that the person no longer has a direct or indirect beneficial
               ownership interest in twenty percent (20%) or more of the
               combined voting power of the Company's then outstanding
               securities, then no Change in Control shall be deemed to have
               occurred;

         (2)   During any period of two (2) consecutive years (not including any
               period prior to December 1, 1998) individuals who at the
               beginning of such two-year period constitute the Board of
               Directors of the Company and any new director or directors
               (except for any director designated by a person who has entered
               into an agreement with the Company to effect a transaction
               described in subparagraph (1), above, or subparagraph (3), below)
               whose election by the Board or nomination for election by the
               Company's stockholders was approved by a vote of at least
               two-thirds of the directors then still in office who either were
               directors at the beginning of the period or whose election or
               nomination for election was previously so approved, cease for any
               reason to constitute at least a majority of the Board (such
               individuals and any such new directors being referred to as the
               "Incumbent Board");

         (3)   Consummation of (x) an agreement for the sale or disposition of
               the Company or all or substantially all of the Company's assets,
               (y) a plan of merger or consolidation of the Company with any
               other corporation, or (z) a similar transaction or series of
               transactions involving the Company (any transaction described in
               parts (x) through (z) of this subparagraph (3) being referred to
               as a "Business Combination"), in each case unless after such a
               Business Combination (I) the stockholders of the Company
               immediately prior to the Business Combination continue to own,
               directly or indirectly, more than sixty percent (60%) of the
               combined voting power of the then outstanding voting securities
               entitled to vote generally in the election of directors of

                                       6

<PAGE>

               the new (or continued) entity (including, but not by way of
               limitation, an entity which as a result of such transaction owns
               the Company, or all or substantially all of the Company's former
               assets either directly or through one or more subsidiaries)
               immediately after such Business Combination, in substantially the
               same proportion as their ownership of the Company immediately
               prior to such Business Combination, (II) no person (excluding any
               entity resulting from such Business Combination or any employee
               benefit plan (or related trust) of the Company or of such entity
               resulting from such Business Combination) beneficially owns,
               directly or indirectly, twenty percent (20%) or more of the then
               combined voting power of the then outstanding voting securities
               of such entity, except to the extent that such ownership existed
               prior to the Business Combination, and (III) at least a majority
               of the members of the board of directors of the entity resulting
               from such Business Combination were members of the Incumbent
               Board at the time of the execution of the initial agreement, or
               of the action of the Board, providing for such Business
               Combination; or

         (4)   Approval by the stockholders of the Company of a complete
               liquidation or dissolution of the Company.

       Notwithstanding any other provision of the Plan, if a Change of Control
   occurs, then the Company shall create a trust or take such other actions as
   are appropriate to protect each participant's deferred compensation account.

            determined by the Required Lenders in their sole discretion on a
            semi-annual basis on September 30 and March 31. In addition, the
            Required Lenders, in their sole discretion, may conduct one
            unscheduled Borrowing Base Amount redetermination subsequent to each

            the Required Lenders. The Borrowing Base Amount also is subject to
            mandatory Quarterly Reductions. The Required Lenders are not
            obligated under any circumstances to establish the Borrowing Base
            Amount based solely on oil and gas valuation data for the Mortgaged

            than 90%; or

            (iii) 1.625% per annum whenever the Borrowing Base Usage under the
            Revolving Line of Credit is less than 50%.

      3. The definition of the term "Quarterly Reduction" in the Agreement is
hereby deleted and restated as follows:

            Base Amount established by the Required Lenders based on each
            scheduled and unscheduled redetermination of the Borrowing Base
            Amount. The Quarterly Reduction will be made on January 31, April
            30, July 31, and October 31 of each year. The Quarterly Reduction
            will be $3,000,000.00 on each of April 30, 2002 and July 31, 2002,
            unless redetermined by the Required Lenders. The Administrative

<PAGE>
            (ii) 0.000% per annum whenever the Borrowing Base Usage under the
            Revolving Line of Credit is less than 90%.

            "THIRD AMENDMENT" shall mean that certain Third Amendment to Amended
            and Restated Credit Agreement dated as of March 1, 2002, among the

      B. BORROWING BASE AMOUNT REDETERMINATION. The Agreement is hereby amended
to reflect that the Borrowing Base Amount as of March 1, 2002, is
$28,000,000.00. The parties also acknowledge that the next regularly scheduled

      C. REVISION TO SECTION 6.2. Section 6.2 of the Agreement is hereby deleted
and restated as follows:

            SECTION 6.2. UNUSED FEE. The Borrower shall pay the Administrative
            Agent for the Pro Rata benefit of the Lenders an unused fee
            calculated as follows: (i) if the Borrowing Base Usage is greater
            than or equal to 90%, the unused fee is 0.50%; (ii) if the Borrowing
            Base Usage is greater than or equal to 50% but less than 90%, the
            unused fee is 0.50%; (iii) if the Borrowing Base Usage is less than
            50%, the unused fee is 0.375%. The unused fee will be payable
            quarterly in arrears, commencing June 30, 2001. The unused portion
            of the Borrowing Base Amount shall be determined on a daily basis by
            subtracting from the Borrowing Base Amount the amount of all
            Revolving Loans outstanding, and by averaging said daily amounts for
            the period for which the fee is to be determined. The Borrower
            hereby authorizes the Administrative Agent to debit its account
            maintained with the Administrative Agent for collection of the
            unused fee.

      D. REVISION TO AFFIRMATIVE COVENANTS.

      1.    Section 12.17 of the Agreement is hereby deleted and restated as
