         (including satisfaction of the conditions precedent set forth in

                                        Revolving Loans to the Company in
                                        accordance with this Section and

                                        discretion, make bids to make

                                        accordance with this Section and

                    (b)      Facility Amount.  In no event may the aggregate
         principal amount of all outstanding Loans (including both the
         Revolving Loans and the Competitive Bid Loans) exceed the Aggregate
         Available Commitment and no Lender shall be obligated to make any Loan
         hereunder if, after giving effect to such Loan, the sum of the
         aggregate outstanding principal amount of all Loans would exceed the
         Aggregate Available Commitment (as then in effect after giving effect
         to any reductions thereof to be effectuated on such day).

                    (c)      All Loans.  Subject to the terms and conditions of
         this Agreement, the Company may borrow, repay and reborrow all Loans
         made under this Agreement at any time prior to the Termination Date.
         The obligations of the Lenders to make Loans shall cease on the
         Termination Date, and any and all Loans outstanding on such date shall
         be due and payable on such date.

                    (d)      Revolving Advances.  Each Revolving Advance
         hereunder shall consist of borrowings made from the several Lenders
         ratably in proportion to the amounts of their respective Commitments.
         The aggregate outstanding amount of Competitive Bid Loans shall reduce
         each Lender's portion of the Aggregate Available Commitment ratably in
         the proportion such Lender's Commitment bears to the Aggregate
         Commitment regardless of which Lender or Lenders makes such
         Competitive Bid Loans.

                    (e)      Competitive Bid Loans.  In addition to Revolving
         Loans pursuant to Section 2.1(d), but subject to the terms and
         conditions of this Agreement (including, without limitation, the
         limitation set forth in Section 2.1(b) as to the maximum aggregate
         principal amount of all outstanding Loans hereunder, the Company may,

         rate per annum of .25%, request the Lenders, prior to the Termination
         Date, to make offers to make Competitive Bid Advances to the Company.
         Each Lender may, but shall have no obligation to, make such offers and
         the Company may, but shall have no obligation to, accept such offers.

         the Aggregate Commitment shall be effective for an initial period from
         the Effective Date to the Original Termination Date; provided that the
         Aggregate Commitment, and concomitantly the Termination Date, may be
         extended for successive one year periods expiring the date which is

                                       19
   26
         extend the Termination Date for such one year period; provided,
         however, that if such Annual Certificate of Extension is delivered to
         the Administrative Agent in the same year in which the Termination
         Date is then scheduled to occur, each Lender shall notify the
         Administrative Agent not fewer than 15 days prior to such Anniversary
         Date, whether it, in the exercise of its sole discretion, will extend
         the Termination Date for such one-year period.  Any Lender which shall
         not timely notify the Administrative Agent whether it will extend the
         Termination Date shall be deemed to not have agreed to extend the
         Termination Date.  No Lender shall have any obligation whatsoever to
         agree to extend the Termination Date.  Any agreement to extend the
         Termination Date by any Lender shall be irrevocable, except as
         provided in Section 2.2(c).

                    (b)      If all the Lenders notify the Administrative Agent
         pursuant to clause (a) of this Section 2.2 of their agreement to
         extend the Termination Date (such Lenders agreeing to extend the
         Termination Date herein called the "Accepting Lenders"), then the
         Administrative Agent shall so notify each Lender and the Company, and
         such extension shall be effective without other or further action by
         any party hereto for such additional one year period.

                    (c)      If Lenders constituting at least the Required
         Lenders approve the extension of the then scheduled Termination Date
         and if one (1) or more of the Lenders shall notify, or be deemed to
         notify, the Administrative Agent pursuant to clause (a) of this
         Section 2.2 that it will not extend the then scheduled Termination
         Date (such Lenders herein called the "Declining Lenders"), then (A)
         the Administrative Agent shall promptly so notify the Company and the
         Accepting Lenders, (B) the Accepting Lenders shall, upon the Company's
         election to extend the then scheduled Termination Date in accordance
         with clause (i) or (ii) below, extend the then scheduled Termination
         Date and (C) the Company shall pursuant to a notice delivered to the
         Administrative Agent, the Accepting Lenders and the Declining Lenders,
         no later than the fifth day following the date by which each Lender is
         required, pursuant to Section 2.2(a), to approve or disapprove the
         requested extension of the Aggregate Commitment, either:

                             (i)        elect to extend the Termination Date
                    with respect to the Accepting Lenders and direct the
                    Declining Lenders to terminate their Commitments, which
                    termination shall become effective on the date which would
                    have been the Termination Date except for the operation of
                    this Section 2.2.  On such date, (x) the Company shall
                    deliver a notice of the effectiveness of such termination
                    to the Declining Lenders with a copy to the Administrative
                    Agent and (y) the Company shall pay in full in immediately
                    available funds all Obligations of the Company owing to the
                    Declining Lenders and (z) upon the occurrence of the events
                    set forth in clauses (x) and (y), the Declining Lenders
                    shall each cease to be a Lender hereunder for all purposes,
                    other than for purposes of Section 14.7, and shall cease to
                    have any obligations or any Commitment hereunder, other
                    than to the Agents pursuant to Section 15.8 and the
                    Administrative Agent shall promptly notify the Accepting
                    Lenders and the Company of the new Aggregate Commitment; or

                             (ii)       elect to extend the Termination Date
                    with respect to the Accepting Lenders and, prior to or no
                    later than the then scheduled Termination Date, (A) to
                    replace one or more of the Declining Lender or Lenders with
                    another lender or lenders reasonably acceptable to the
                    Administrative Agent (such lenders herein called the
                    "Replacement Lenders") and (B) the Company shall pay in
                    full in immediately available funds all Obligations of the
                    Company owing to the Declining Lenders which are not being
                    replaced, as provided in clause (i) above; provided that
                    (x) the Replacement Lender or Lenders shall purchase, and
                    the Declining Lender or Lenders shall sell, the Notes of
                    the Declining Lender





                                       20
   27
                    or Lenders being replaced and the Declining Lender's or
                    Lenders' rights hereunder without recourse or expense to,
                    or warranty by, such Declining Lender or Lenders being
                    replaced for a purchase price equal to the aggregate
                    outstanding principal amount of the Note or Notes payable
                    to such Declining Lender or Lenders plus any accrued but
                    unpaid interest on such Note or Notes and accrued but
                    unpaid fees in respect of such Declining Lender's or
                    Lenders' Loans and Commitments hereunder, and (y) all
                    obligations of the Company owing under or in connection
                    with this Agreement to the Declining Lender or Lenders
                    being replaced (including, without limitation, such
                    increased costs, breakage fees payable under Section 6.3
                    and all other costs and expenses payable to each such
                    Declining Lender) shall be paid in full in immediately
                    available funds to such Declining Lender or Lenders
                    concurrently with such replacement, and (z) upon the
                    payment of such amounts referred to in clauses (x) and (y),
                    the Replacement Lender or Lenders shall each constitute a
                    Lender hereunder and the Declining Lender or Lenders being
                    so replaced shall no longer constitute a Lender (other than
                    for purposes of Section 14.7), and shall no longer have any
                    obligations hereunder, other than to the Agents pursuant 
                    to Section 15.8; or

                             (iii)      elect to revoke and cancel the
                    extension request in such Annual Certificate of Extension
                    by giving notice of such revocation and cancellation to the
                    Administrative Agent (which shall promptly notify the
                    Lenders thereof) no later than the fifth day following the
                    date by which each Lender is required, pursuant to Section
                    2.2(a), to approve or disapprove the requested extension of
                    the Aggregate Commitment.

         If the Company fails to timely provide the election notice referred to
in this clause(c), the Company shall be deemed to have revoked and cancelled
the extension request in the Annual Certificate of Extension and to have
elected not to extend the Aggregate Commitment, and the concomitant Termination
Date with respect to the Accepting Lenders, and on the then scheduled
Termination Date the Company shall repay in full all amounts outstanding under
the Loans.

         2.3.       Borrowing Base.

                    (a)      Initial Borrowing Base; Scheduled Semi-Annual and
         Discretionary Determinations of the Borrowing Base; Procedures for
         Determination of the Borrowing Base.  The initial Borrowing Base shall
         be $450,000,000.  The Borrowing Base shall be redetermined upon
         receipt by the Administrative Agent, the Co-Agent and the Lenders of
         the relevant Approved Engineers' Report or Company's Engineers'
         Report, as the case may be, pursuant to Sections 2.3(b) or (e),
         4.2(d), 9.1(d), (e) or (f).  Additionally, the Borrowing Base may be
         redetermined under each of the circumstances set forth in Sections
         2.3(d), 2.3(e) and 11.1.  The redeterminations of the Borrowing Base
         described in the preceding sentences shall be made as follows:   The
         Administrative Agent and Co-Agent shall make a determination of the
         Borrowing Base in accordance with the criteria described in clause (c)
         of this Section 2.3 within thirty (30) days after receipt of the
         Approved Engineers' Report or the Company's Engineers' Report, as the
         case may be.  Within ten (10) days following such determination, the
         Administrative Agent shall notify the Lenders in writing of such
         determination.  Each Lender shall notify the Administrative Agent in
         writing, by telex or by facsimile transmission whether it approves or
         disapproves of any such determination of the Borrowing Base within ten
         (10) Business Days of its receipt of such notice from the
         Administrative Agent; provided that any Lender which does not so
         notify the Administrative Agent shall be deemed to have approved of
         such determination.  Upon the approval (or deemed approval) by the
         Required Lenders, such determination shall thereafter be the Borrowing
         Base, and the Administrative Agent shall within five (5) days of such
         approval notify the Company in writing of such redetermined Borrowing
         Base.  The





                                       21
   28
         Administrative Agent shall promptly notify the Company and the Lenders
         of any change in the Borrowing Base.

                    (b)      Determination of Borrowing Base at Request of
         Company.  The Company may request one Borrowing Base determination
         between regularly scheduled semi-annual redeterminations of the
         Borrowing Base by delivery to the Administrative Agent, the Co-Agent
         and the Lenders of a written request for such determination; provided
         that a deemed request for a determination of the Borrowing Base
         pursuant to Section 11.1(c), (d) or (e) shall not preclude the
         Company's requesting a Borrowing Base determination to which it is
         otherwise entitled pursuant to this clause (b).  In connection with
         such determination the Company shall deliver to the Administrative
         Agent, the Co-Agent and the Lenders such reports and information
         concerning the Properties (which may include in the Administrative
         Agent's and Co-Agent's sole discretion an Approved Engineers' Report
         or a Company's Engineers' Report as of such date) as the
         Administrative Agent and the Co- Agent shall deem appropriate in their
         sole discretion.

                    (c)      Criteria for Determination of the Borrowing Base.
         Each determination by the Administrative Agent and the Co-Agent and
         the approval by the Required Lenders of the Borrowing Base
         attributable to the Properties owned by the Company and its
         Subsidiaries including Properties owned through partnerships (but not
         to exceed in each case an undivided share of such Properties equal to
         the Company's ownership share of such partnerships) shall be made by
         them in the exercise of their respective sole discretion based on
         their then current engineering criteria and oil and gas lending
         criteria, all as determined using the then most recently received
         Approved Engineers' Report or Company's Engineers' Report, as the case
         may be, and, subject to the approval of the Required Lenders to the
         extent set forth in clause (a) of this Section 2.3, shall be
         conclusive and binding in the absence of manifest error.

                    (d)      Redeterminations of Borrowing Base Upon Material
         Adverse Effect.  In the event of:

                             (i)        the assertion or filing of any adverse
                    claim, defect or encumbrance affecting or purporting to
                    affect the title of the Company or any Subsidiary to any
                    Property; or

                             (ii)       any blow out or other casualty
                    affecting any Property or the production of oil and gas
                    therefrom; or

                             (iii)      any withholding after one hundred
                    twenty (120) days following commencement of production by
                    any Person of sums due the Company or any Subsidiary in
                    respect of Hydrocarbons produced, which withholding results
                    from an allegation or claim affecting such Person's rights
                    to such payment;

         which would have or be a Material Adverse Effect, the Administrative
         Agent and the Co-Agent shall have the right in their sole discretion
         to reduce the Borrowing Base, either temporarily or permanently, by
         the amount included therein with respect to the interest as to which a
         claim, defect, encumbrance, withholding or dispute has arisen or
         exists or a casualty has occurred.  The failure of the Administrative
         Agent and the Co-Agent to make any such reduction upon receipt of any
         notice with respect to any such claim, dispute or casualty shall not
         preclude their later election to so reduce the Borrowing Base.

                    (e)      Redetermination of Borrowing Base Upon Material
         Changes.  In the event that "material changes" occur between the dates
         of determination of the Borrowing Base in (i) oil and/or gas prices,
         (ii) taxes, (iii) anticipated rates or amounts of production from any
         Properties included in the Borrowing Base, (iv) the Company's or any
         Subsidiary's, as the case may be, title or purported title to the
         Properties, (v) operating, lease, royalty and other arrangements
         relating





                                       22
   29
         to the Properties or (vi) operating costs with respect to the
         Properties, then in any such event the Administrative Agent and the
         Co-Agent may, in their sole discretion, redetermine the Borrowing Base
         in accordance with the standards set forth in Section 2.3(c) prior to
         the receipt of either a new Approved Engineers' Report or a new
         Company's Engineers' Report by adjusting the Borrowing Base to reflect
         the changes which have occurred.  For the purposes hereof, "material
         changes" shall be deemed to have occurred for purposes of this Section
         2.3(e) when such changes would in the aggregate result in a material
         decrease in the Borrowing Base as determined by the Administrative
         Agent and the Co-Agent in their sole and absolute discretion.

                    (f)      Reduction of Borrowing Base Upon Sales of Certain
         Properties.  Upon consummation of the Sale of any Property in the
         Borrowing Base constituting a permitted and designated Sale under
         clause (iii) of Section 11.3, the Borrowing Base shall be reduced on
         account of such Sale by an amount equal to the proceeds of such Sale
         net of reasonable incidental brokerage and legal costs actually paid
         to third parties, net of taxes associated with such Sale payable in
         cash concurrently with the consummation of such Sale, and net of
         federal and state income taxes estimated to be due in respect of such
         Sale by the Company acting reasonably and in good faith, provided
         reserves for such taxes are established by the Company.  Upon the
         consummation of the Sale of any Property in the Borrowing Base
         constituting a permitted Sale under clause (iv) of Section 11.3, the
         Borrowing Base shall be reduced by an amount equal to the amount of
         the mandatory prepayment, if any, required to be made under Section
         4.2(d) on account of such Sale.

                    (g)      Title Warranty.  Delivery to the Lenders of any
         Approved Engineers' Report or Company's Engineers' Report shall be
         deemed to be a reaffirmation as of the date of delivery of such report
         of the representation and warranties in Section 8.14.

         2.4.       (Intentionally Omitted.)

         2.5.       Facility Fee; Other Fees.

                    (a)      Facility Fee.  (i) The Company agrees to pay to
         the Administrative Agent for the account of each Lender a facility fee
         for the period from (and including) the date hereof to the Termination
         Date, at the applicable rate per annum set forth below on such
         Lender's ratable portion of the Aggregate Available Commitment as in
         effect from time to time; provided, however, that a reduction in a
         Lender's portion of the Aggregate Available Commitment pursuant to
         Section 2.1(d) shall not reduce such Lender's ratable portion of the
         Aggregate Available Commitment for the purposes of this Section
         2.5(a)(i):

                    (ii) The Company agrees to pay to the Administrative Agent
         for the account of each Lender a facility fee for the period from (and
         including) the date hereof to the Termination Date, at one-half of the
         rate applicable per annum set forth in clause (i) above on such
         Lender's ratable portion of the Aggregate Unavailable Commitment as in
         effect from time to time; provided, however, that a reduction in a
         Lender's portion of the Aggregate Available Commitment pursuant to
         Section 2.1(d) shall not reduce such Lender's ratable portion of the
         Aggregate Unavailable Commitment for the purposes of this Section

         3.3.       Method of Selecting Rate Options and Interest Periods for

Each Eurodollar Revolving Advance shall bear interest from and including the
first day of the Interest Period applicable thereto to (but not including) the
last day of such Interest Period at the interest rate determined from time to
time as applicable to such Eurodollar Revolving Advance.  The Company shall
select Interest Periods with respect to Eurodollar Revolving Advances so that
it is not necessary to pay a Eurodollar Revolving Advance prior to the last day
of the applicable Interest Period in order to make the mandatory repayment on
the Termination Date.

                    Bid Loan, its "Stated Maturity Date") for the proposed
                    Competitive Bid Advance (which Stated Maturity Date may not

                    Advance, the Interest Period applicable thereto (which may
                    not end after the Termination Date); provided that the
                    final day of the Interest Period applicable to each
                    Eurodollar Bid Rate Loan shall be the Stated Maturity Date

                    The Company may request offers to make Competitive Bid
         Loans for more than one Interest Period in a single Competitive Bid
         Quote Request.  No Competitive Bid Quote Request shall be given within
         5 Business Days (or such other number of days as the Company and the
         Administrative Agent may agree) of any other Competitive Bid Quote
         Request.  A Competitive Bid Quote Request that does not conform
         substantially to the format of Exhibit E hereto shall be rejected, and
         the Administrative Agent shall promptly notify the Company of such
         rejection by telex or telecopy.

                    (b)      Invitation for Competitive Bid Quotes.  Promptly
         and in any event before the close of business on the same Business Day
         of receipt of a Competitive Bid Quote Request that is not rejected
         pursuant to Section 3.4(a), the Administrative Agent shall send to
         each of the Lenders by telex or telecopy an Invitation for Competitive
         Bid Quotes substantially in the form of Exhibit H hereto, which shall

         which such Competitive Bid Quote Request relates in accordance with
         this Section 3.4.

                    (c)      Submission and Contents of Competitive Bid Quotes.

                    (i)      Each Lender may, in its sole discretion, submit a
                             Competitive Bid Quote containing an offer or
                             offers to make Competitive Bid Loans in response
                             to any Invitation for Competitive Bid Quotes.
                             Each Competitive Bid Quote must comply with the
                             requirements of this Section 3.4(c) and must be
                             submitted to the Administrative Agent by telex or
                             telecopy at its offices specified pursuant to
                             Article XVIII not later than (a) 10:00 a.m.
                             (Chicago time) at least three Business Days prior
                             to the proposed Borrowing Date, in the case of a
                             Eurodollar Auction or (b) 9:00 a.m. (Chicago time)
                             on the proposed Borrowing Date, in the case of a
                             Floating Rate Auction (or, in either case upon
                             reasonable prior notice to the Lenders, such other
                             time and date as the Company and the
                             Administrative Agent may agree); provided that
                             Competitive Bid Quotes submitted by First Chicago
                             may only be submitted if the Administrative Agent
                             or First Chicago notifies the Company of the terms
                             of the offer or offers contained therein not later
                             than 15 minutes prior to the latest time at which
                             the relevant Competitive Bid Quotes must be
                             submitted by the other Lenders.  Subject to
                             Articles VII and XII, any Competitive Bid Quote so
                             made shall be irrevocable except with the written
                             consent of the Administrative Agent given on the
                             instructions of the Company.

                    (ii)     Each Competitive Bid Quote shall be in
                             substantially the form of Exhibit K hereto and
                             shall in any case specify:

                             a.         the proposed Borrowing Date, which
                    shall be the same as that set forth in the applicable
                    Invitation for Competitive Bid Quotes;

                             b.         the Stated Maturity Date and the
                    principal amount of the Competitive Bid Loan for which each
                    such offer is being made, which principal amount (1) may be
                    greater than, less than or equal to the Commitment of the
                    quoting Lender, (2) must be at least $10,000,000 and an
                    integral multiple of $1,000,000 in the case of a Eurodollar
                    Bid Rate Advance and at least $7,000,000 and an integral
                    multiple of $500,000 in the case of a Floating Bid Rate
                    Advance, and (3) may not exceed the principal amount of
                    Competitive Bid Loans for which offers were requested;

                             c.         the Competitive Bid Margin offered for
                    each such Competitive Bid Loan;





                                       26
   33
                             d.         the minimum amount, if any, of the
                    Competitive Bid Loan which may be accepted by the Company;
                    and

                             e.         the identity of the quoting Lender.

                    (iii)    The Administrative Agent shall reject any
                             Competitive Bid Quote that:

                             a.         is not substantially in the form of
                    Exhibit K hereto or does not specify all of the information
                    required by Section 3.4(c)(ii);

                             b.         contains qualifying, conditional or
                    similar language, other than any such language contained in
                    Exhibit K hereto;

                             c.         proposes terms other than or in
                    addition to those set forth in the applicable Invitation
                    for Competitive Bid Quotes; or

                             d.         arrives after the time set forth in
                    Section 3.4(c)(i).

                    If any Competitive Bid Quote shall be rejected pursuant to
         this Section 3.4(c)(iii), then the Administrative Agent shall notify
         the relevant Lender of such rejection as soon as practical.

                    (d)      Notice to Company.  The Administrative Agent shall
         promptly notify the Company of the terms (i) of any Competitive Bid
         Quote submitted by a Lender that is in accordance with Section 3.4(c)
         and (ii) of any Competitive Bid Quote that amends, modifies or is
         otherwise inconsistent with a previous Competitive Bid Quote submitted
         by such Lender with respect to the same Competitive Bid Quote Request.
         Any such subsequent Competitive Bid Quote shall be disregarded by the
         Administrative Agent unless such subsequent Competitive Bid Quote
         specifically states that it is submitted solely to correct a manifest
         error in such former Competitive Bid Quote.  The Administrative
         Agent's notice to the Company shall specify the aggregate principal
         amount of Competitive Bid Loans for which offers have been received
         for each Interest Period or Stated Maturity Date specified in the
         related Competitive Bid Quote Request and the respective principal
         amounts and Eurodollar Bid Rates or Floating Bid Rates, as the case
         may be, so offered.

                    (e)      Acceptance and Notice by Company.  Not later than
         (i) 11:00 a.m. (Chicago time) at least three Business Days prior to
         the proposed Borrowing Date, in the case of a Eurodollar Auction or
         (ii) 10:00 a.m. (Chicago time) on the proposed Borrowing Date, in the
         case of a Floating Rate Auction (or, in either case upon reasonable
         prior notice to the Lenders, such other time and date as the Company
         and the Administrative Agent may agree), the Company shall notify the
         Administrative Agent of its acceptance or rejection of the offers so
         notified to it pursuant to Section 3.4(d); provided, however, that the
         failure by the Company to give such notice to the Administrative Agent
         shall be deemed to be a rejection of all such offers.  In the case of
         acceptance, such notice (a "Competitive Bid Borrowing Notice") shall
         specify the aggregate principal amount and the Interest Period and
         Stated Maturity Date of each offer that is accepted.  The Company may
         accept any Competitive Bid Quote in whole or in part (subject to the
         terms of Section 3.4(c)(ii)d); provided that:

                             a.         the aggregate principal amount of each
                    Competitive Bid Advance may not exceed the applicable
                    amount set forth in the related Competitive Bid Quote
                    Request;





                                       27
   34
                             b.         acceptance of offers may only be made
                    on the basis of ascending Eurodollar Bid Rates or Floating
                    Bid Rates, as the case may be; and

                             c.         the Company may not accept any offer
                    that is described in Section 3.4(c)(iii) or that otherwise
                    fails to comply with the requirements of this Agreement.

                    (f)      Allocation by Administrative Agent.  If offers are
         made by two or more Lenders with the same Eurodollar Bid Rates or
         Floating Rates, as the case may be, for a greater aggregate principal
         amount than the amount in respect of which offers are accepted for the
         related Interest Period, the principal amount of Competitive Bid Loans
         in respect of which such offers are accepted shall be allocated by the
         Administrative Agent among such Lenders as nearly as possible (in such
         multiples, not greater than $1,000,000, as the Administrative Agent
         may deem appropriate) in proportion to the aggregate principal amount
         of such offers; provided, however, that no Lender shall be allocated a
         portion of any Competitive Bid Advance which is less than the minimum
         amount which such Lender has indicated that it is willing to accept.
         Allocations by the Administrative Agent of the amounts of Competitive
         Bid Loans shall be conclusive in the absence of manifest error.  The
         Administrative Agent shall promptly, but in any event on the same
         Business Day, notify each Lender of its receipt of a Competitive Bid
         Borrowing Notice and the aggregate principal amount of such
         Competitive Bid Advance allocated to each participating Lender.

         3.5.       Minimum Amount of Each Advance.  Each requested Eurodollar
Bid Rate Advance and Eurodollar Revolving Advance shall be in the minimum
amount of $10,000,000 (and in multiples of $1,000,000 if in excess thereof),
and each requested Floating Bid Rate Advance and Floating Rate Revolving
Advance shall be in the minimum amount of $7,000,000 (and in multiples of
$500,000 if in excess thereof); provided, however, that any Floating Bid Rate
Advance and any Floating Rate Revolving Advance may be in the amount of the
difference between (i) the Aggregate Available Commitment minus (ii) the sum of
the outstanding principal amount of all Loans.

         3.6.       Continuation and Conversion Elections.  By providing a
Continuation/Conversion Notice to the Administrative Agent on or before 11:00
a.m. Chicago time, in the case of a Eurodollar Revolving Loan, or 10:00 a.m.
Chicago time, in the case of a Floating Rate Revolving Loan, on a Business Day,
the Company may from time to time irrevocably elect, on, in the case of a
Eurodollar Revolving Loan, not less than three nor more than five, and in the
case of a Floating Rate Revolving Loan not less than one or more than three,
Business Days' notice, that all, or any portion in an aggregate minimum amount
of $10,000,000 and an integral multiple of $1,000,000 or the remaining balance
of any Revolving Loans be, in the case of Floating Rate Revolving Loans
converted into Eurodollar Revolving Loans or, in the case of Eurodollar
Revolving Loans converted into Floating Rate Revolving Loans or continued as
Eurodollar Revolving Loans (in the absence of delivery of a
Continuation/Conversion Notice with respect to any Eurodollar Revolving Loan at
least three Business Days before the last day of the then current Interest
Period with respect thereto, such Eurodollar Revolving Loan shall, on such last
day, automatically convert to a Floating Rate Revolving Loan); provided,
however, that no portion of the outstanding principal amount of any Loans may
be continued as, or be converted into, a Eurodollar Advance when any Default
has occurred and is continuing.

         3.7.       Telephonic Notices.  The Company hereby authorizes the
Lenders and the Administrative Agent to extend Advances, effect Rate Option
selections and submit Competitive Bid Quotes based on telephonic notices made
by any Person or Persons the Administrative Agent or any Lender in good faith
believes to be acting on behalf of the Company.  The Company agrees to deliver
promptly to the Administrative Agent a written confirmation of each telephonic
notice signed by an Authorized Officer.  If the written confirmation differs in
any material respect from the action taken by the Administrative Agent and the
Lenders, the records of the Administrative Agent and the Lenders shall govern
absent manifest error.





                                       28
   35
         3.8.       Rate after Maturity.  Except as provided in the next
sentence, any Advance not paid at maturity, whether by acceleration or
otherwise, shall bear interest until paid in full at a rate per annum equal to
the Floating Revolving Rate plus 2%.  In the case of a Eurodollar Advance the
maturity of which is accelerated, such Eurodollar Advance shall bear interest
for the remainder of the applicable Interest Period, at the higher of the rate
(including the Eurodollar Spread or the Competitive Bid Margin, as applicable)
otherwise applicable to such Interest Period plus 2% per annum or the Floating
Revolving Rate plus 2% per annum.

         3.9.       Interest Payment Dates; Determination of Interest and Fees.

                    (a)      Interest Payment Dates.

                             (i)        Interest accrued and unpaid on each
                    Floating Rate Revolving Advance shall be payable on each
                    Payment Date and on any date on which such Floating Rate
                    Revolving Advance is paid or prepaid, whether due to
                    acceleration or otherwise.  Interest accrued on each
                    Eurodollar Revolving Advance shall be payable on the last
                    day of its applicable Interest Period and on any date on
                    which such Eurodollar Revolving Advance is prepaid, whether
                    due to acceleration or otherwise.  Interest accrued on each
                    Eurodollar Revolving Advance having an Interest Period
                    longer than three (3) months shall also be payable on the
                    last day of each three-month interval during such Interest
                    Period.

                             (ii)       Interest on the outstanding principal
                    amount of Competitive Bid Loans shall be payable on the
                    Stated Maturity Date for each such Competitive Bid Loan;
                    provided, however, that in the case of a Eurodollar Bid
                    Rate Advance having an Interest Period longer than three
                    (3) months, interest accrued on such Eurodollar Bid Rate
                    Advance shall also be payable on the last day of each
                    three-month interval during such Interest Period.

Interest shall be payable for the day an Advance is made but not for the day of
any payment on the amount paid if payment is received prior to noon (local
time) at the place of payment.  If any payment of principal of, or interest on,
an Advance shall become due on a day which is not a Business Day, such payment
shall be made on the next succeeding Business Day (except as provided in the
definition of Interest Period) and, in the case of a principal payment, such
extension of time shall be included in computing interest in connection with
such payment.

                    (b)      Determination of Interest and Fees.  Interest on
         any Advance or portion thereof bearing interest at the Floating
         Revolving Rate or the Floating Bid Rate and facility fees shall be
         calculated for actual days elapsed on the basis of a 365- or, if
         applicable, 366-day year, and all other interest and fees shall be
         calculated for actual days elapsed on the basis of a 360-day year.
         Changes in the Alternate Base Rate Spread and the Eurodollar Spread
         attributable to a change in the Debt/Capitalization Ratio or to a
         change in the Company's Long-term Debt Rating, if any, shall be
         effective on the forty-fifth (45th) day of a calendar quarter.

         3.10.      Notification of Advances, Interest Rates, Prepayments and
Commitment Reductions.  Promptly after receipt thereof, the Administrative
Agent will notify each Lender of the contents of each commitment reduction
notice, Borrowing Notice, Continuation/Conversion Notice, Competitive Bid Quote
Request and repayment notice received by it hereunder.  The Administrative
Agent will notify each Lender of the Eurodollar Rate applicable to each
Eurodollar Advance promptly upon determination of such Eurodollar Rate and will
give each Lender prompt notice of each change in the Alternate Base Rate.  Each
Reference Lender agrees to furnish timely information for the purpose of
determining the Eurodollar Rate.

         3.11.      Non-Receipt of Funds by the Administrative Agent.  Unless
the Company or a Lender, as the case may be, notifies the Administrative Agent
prior to the date on which it is scheduled to make payment to the
Administrative Agent





                                       29
   36
of (i) in the case of a Lender, the proceeds of a Loan or (ii) in the case of
the Company, a payment of principal, interest, fees or other amounts to the
Administrative Agent for the account of the Lenders or any Agent, that it does
not intend to make such payment, the Administrative Agent may assume that such
payment has been made.  The Administrative Agent may, but shall not be
obligated to, make the amount of such payment available to the intended
recipient in reliance upon such assumption.  If such Lender or the Company, as
the case may be, has not in fact made such payment to the Administrative Agent,
the recipient of such payment shall, on demand by the Administrative Agent,
repay to the Administrative Agent the amount so made available together with
interest thereon in respect of each day during the period commencing on the
date such amount was so made available by the Administrative Agent until the
date the Administrative Agent recovers such amount at a rate per annum equal to
(i) in the case of payment by a Lender or any Agent, the Federal Funds
Effective Rate for such day or (ii) in the case of payment by the Company, the
interest rate applicable to the relevant Loan or, in the case of payments in
respect of interest, fees or other amounts, at a rate equal to the Floating
Rate.


                                   ARTICLE IV

              MANDATORY PAYMENTS; REDUCTIONS OF COMMITMENTS; ETC.

         4.1.       (Intentionally Omitted.)

         4.2.       Mandatory Prepayments.

                    (a)      Mandatory Prepayment on Account of Excess of
         Outstandings Over Aggregate Available Commitment.  In the event that
         after giving effect to all other payments or prepayments required to
         be made under this Section 4.2 on any Business Day the aggregate
         outstanding principal amount of the Loans shall at any time exceed the
         Aggregate Available Commitment, the Company shall within ninety (90)
         days make a mandatory prepayment on the Loans in an amount equal to
         such excess together with all interest accrued on the amount of such
         prepayment to the date thereof.  Notwithstanding that the Company
         shall have a 90-day period in which to make any mandatory prepayment
         specified in this Section 4.2(a), (i) the Company shall not be
         entitled to borrow Loans during such period without meeting the test
         under Section 2.1(b) and (ii) the Company shall make all other
         prepayments and payments required under or in connection with this
         Agreement as required; provided, that for purposes of the foregoing
         provisions of this sentence the conversion of an outstanding
         Eurodollar Loan into a Floating Rate Loan during such period shall not
         be deemed to be the borrowing of a Loan.

                    (b)      Mandatory Prepayment on Account of Sales of
         Certain Properties Included in the Borrowing Base.  Promptly upon the
         consummation of any Sale of any Property included in the Borrowing
         Base constituting (and designated by the Company in a notice to the
         Administrative Agent as constituting) a permitted Sale under clause
         (iii) of Section 11.3 and in any event within three (3) Business Days
         thereof, the Company shall make a mandatory prepayment hereunder equal
         to the amount, if any, by which the aggregate outstanding principal
         amount of all Loans on the date of such mandatory prepayment exceeds
         the Aggregate Available Commitment (as then in effect after giving
         effect to any reduction thereof resulting from such Sale).

                    (c)      (Intentionally Omitted.)

                    (d)      Mandatory Prepayment on Account of Extraordinary
         Sales of Properties.  In the event the Company or any Subsidiary
         proposes to consummate a Sale of any Property, which Sale is not
         otherwise permitted under clause (i) or (ii) of Section 11.3 or
         otherwise permitted and designated under clause (iii) of Section 11.3,
         the Company shall promptly notify the Administrative Agent, the
         Co-Agent and the Lenders of such proposed Sale, which notice shall
         describe such Property and, if known,





                                       30
   37
         the proposed terms of Sale.  In connection therewith the Company shall
         deliver to the Administrative Agent, the Co-Agent and the Lenders such
         reports and information concerning such Property (which may include in
         the Administrative Agent's and Co-Agent's sole discretion an Approved
         Engineers' Report or a Company's Engineers' Report as of such date)
         and such Sale as the Administrative Agent and the Co-Agent shall deem
         appropriate in their sole discretion; provided, however, that in the
         event the Company or any Subsidiary proposes to consummate a Sale of
         the type described in this Section 4.2(d), with respect to a Property
         not included within the Borrowing Base, no mandatory prepayment shall
         be required; and further, provided, that in no event shall the
         Borrowing Base be reduced by an amount in excess of the proceeds of
         such Sale net of costs, charges, and taxes incidental to the Sale, as
         provided in Section 2.3(f) for Sales pursuant to clause (iii) of
         Section 11.3.  Promptly following receipt of such report and
         information, and upon approval of such Sale by the Administrative
         Agent and the Co-Agent, the Administrative Agent and the Co-Agent
         shall make a recommendation to the Lenders in writing of the amount of
         prepayment that the Company shall be required to make under this
         Section 4.2(d) (which amount shall also be the amount of the reduction
         in the Borrowing Base pursuant to Section 2.3(f)), which
         recommendation shall be made by the Administrative Agent and the
         Co-Agent in the exercise of their sole discretion.  Each Lender shall
         notify the Administrative Agent in writing, by telex or by facsimile
         transmission whether it approves or disapproves (which approval or
         disapproval shall be made by each Lender in the exercise of its sole
         discretion) of such recommendation by the Administrative Agent and the
         Co-Agent within ten (10) Business Days of its receipt of such
         recommendation from the Administrative Agent; provided, that any
         Lender which does not so notify the Administrative Agent shall be
         deemed to have approved of such Sale, such amount of prepayment and
         such reduction in the Borrowing Base.  Upon the approval of the
         Required Lenders, the Administrative Agent shall promptly notify the
         Company of such determination.  The Company promptly upon the
         consummation of any such permitted Sale and in any event within three
         (3) Business Days thereof, shall, if required, make a mandatory
         prepayment hereunder in the amount so determined in accordance with
         this clause (d).

                    (e)      Application of Mandatory Prepayments.  Each
         mandatory prepayment made under this Section 4.2 shall be applied (i)
         first, ratably among the Lenders with respect to any principal and
         interest due in connection with Revolving Loans, (ii) second, after
         all amounts described in clause (i) have been satisfied, ratably among
         those Lenders for whom any payment of principal and interest is due in
         connection with any Competitive Bid Loans and (iii) third, after all
         amounts described in clauses (i) and (ii) have been satisfied, ratably
         to any other Obligations then due.

         4.3.       Voluntary Prepayments.  The Company may from time to time,
at its option, prepay outstanding Advances, upon three (3) Business Days' prior
notice to the Administrative Agent in the case of a Eurodollar Advance, or upon
one (1) Business Day's prior notice to the Administrative Agent in the case of
a Floating Rate Advance; provided that each such prepayment shall be in a
minimum aggregate amount of $4,000,000 or any integral multiple of $1,000,000
in excess thereof without penalty or premium, except that if such prepayment of
a Eurodollar Loan occurs prior to a last day of any applicable Interest Period,
the Company shall also pay the amount specified in Section 6.3 at the time of
such prepayment.  Such prepayments shall be applied, at the Company's option,
against outstanding Revolving Loans and Competitive Bid Loans and against
installments or amounts due on account thereof in such order of application as
the Company shall direct; provided, that if the Company fails to direct an
order of application at or prior to the time of such notice of prepayment, then
such prepayments shall be applied (i) first, ratably among the Lenders with
respect to any principal and interest due in connection with Revolving Loans,
(ii) second, after all amounts described in clause (i) have been satisfied,
ratably among those Lenders for whom any payment of principal and interest is
due in connection with any Competitive Bid Loans and (iii) third, after all
amounts described in clauses (i) and (ii) have been satisfied, ratably to any
other





                                       31
   38
Obligations then due; provided, further, that if, at the time of any such
prepayment, any Default shall have occurred and shall be continuing, then the
holders of the Obligations shall share such prepayment on a pro rata basis,
based on the respective amount of Obligations owing to each such holder
(whether or not matured and currently payable and whether consisting of
principal, accrued interest, fees, expenses, indemnities or other types of
Obligations) as of the date of occurrence of such Default.

         4.4.       Method of Payment.  All payments of principal, interest,
and fees hereunder shall be made by noon (local time at the place of payment)
on the date when due in immediately available funds to the Administrative Agent
at the Administrative Agent's address specified pursuant to Article XVIII, or
at any other single Lending Installation of the Administrative Agent specified
not less than five (5) days prior to the date when due in writing by the
Administrative Agent to the Company and shall be applied (i) first, ratably
among the Lenders with respect to any principal and interest due in connection
with Revolving Loans, (ii) second, after all amounts described in clause (i)
have been satisfied, ratably among those Lenders for whom any payment of
principal and interest is due in connection with any Competitive Bid Loans and
(iii) third, after all amounts described in clauses (i) and (ii) have been
satisfied, ratably to any other Obligations then due; provided, however, that,
if, at the time of any such payment, any Default shall have occurred and shall
be continuing, then the holders of the Obligations shall share such payment on
a pro rata basis, based on the respective amount of Obligations owing to each
such holder (whether or not matured and currently payable and whether
consisting of principal, accrued interest, fees, expenses, indemnities or other
types of Obligations) as of the date of occurrence of such Default.  As between
the Company and any Lender, the timely receipt of any payment by the
Administrative Agent from the Company for the account of such Lender shall
constitute receipt by such Lender.  Each payment delivered to the
Administrative Agent for the account of any Lender shall be delivered promptly
by the Administrative Agent to such Lender in the same type of funds which the
Administrative Agent received at its address specified pursuant to Article
XVIII or at any Lending Installation specified in a notice received by the
Administrative Agent from such Lender.  Each of the Company and the
Administrative Agent shall be deemed to have complied with this Section 4.4
with respect to any payment if it shall have initiated a wire transfer to the
appropriate recipient thereof and furnished such recipient with the identifying
number of such wire transfer.

         4.5.       Notes.  Each Lender is hereby authorized to record the
principal amount of each of its Loans and each repayment thereof, on the
schedule attached to each of its Notes, provided, however, that the failure to
so record shall not affect the Company's obligations under any such Note.

         4.6.       Voluntary Reductions of Commitments.  The Company may
permanently reduce the Aggregate Commitment in whole, or in part, ratably among
the Lenders, in a minimum aggregate amount of $5,000,000 or any integral
multiple of $1,000,000 in excess thereof; provided, however, that the amount of
the Aggregate Commitment may not be reduced to an amount which would cause it
to be less than the outstanding principal amount of the Loans.  All accrued
facility fees shall be payable on the effective date of any such reduction or
termination of the Aggregate Commitment.

         4.7.       Voluntary and Mandatory Prepayments.  Any prepayments of
principal of the Loans, whether voluntary or mandatory, shall include accrued
interest to, but not including, the date of the prepayment on the principal
amount being prepaid.

                         CHANGE IN CIRCUMSTANCES; TAXES

         6.1.       Yield Protection.  If any law or any governmental or
quasi-governmental rule, regulation, policy, guideline or directive (whether or
not having the force of law), or any reasonable interpretation thereof, or
compliance of any Lender with such,

                    (a)      imposes or increases or deems applicable any
         reserve, assessment, insurance charge, special deposit or similar
         requirement against assets of, deposits with or for the account of, or
         credit extended by, any Lender or any applicable Lending Installation
         (other than reserves and assessments taken into account in determining
         the interest rate applicable to Eurodollar Advances), or

                    (b)      imposes any other condition the result of which is
         to increase the cost to any Lender or any applicable Lending
         Installation of making, funding or maintaining Loans or reduces any
         amount receivable by any Lender or any applicable Lending Installation
         in connection with Loans, or requires any Lender or any applicable
         Lending Installation to make any payment calculated by reference to
         the amount of Loans held or interest received, by an amount reasonably
         deemed material by such Lender,

then, within 15 days of demand by such Lender, the Company shall pay such
Lender that portion of such increased expense incurred or reduction in an
amount received which such Lender reasonably determines is attributable to
making, funding and maintaining its Loans and its Commitment.

         6.2.       Availability of Rate Options.  If any Lender determines
that maintenance of its Eurodollar Loans at a suitable Lending Installation
would violate any applicable law, rule, regulation or directive, whether or not
having the force of law, (i) the Administrative Agent shall suspend the
availability of the Eurodollar Rate with respect to such Lender until such time
as such situation is no longer the case, (ii) any Eurodollar Loans from such
Lender then outstanding shall bear interest at the Floating Rate for the
remainder of the Interest Period applicable to such Loan and (iii) until such
time as such situation is no longer the case, any Eurodollar Advance made
thereafter shall consist of a Floating Rate Loan made by such Lender(s) and
Eurodollar Loans made by each other Lender.  If the Required Lenders reasonably
determine that deposits of a type or maturity appropriate to match fund
Eurodollar Advances are not available, the Administrative Agent shall suspend
the availability of the Eurodollar Rate with respect to any Eurodollar Advances
made after the date of any such determination until such time as such situation
is no longer the case.  If the Required Lenders determine that the Eurodollar
Rate does not accurately reflect the cost of making a Eurodollar Advance at
such Eurodollar Rate, then, if for any reason whatsoever the provisions of
Section 6.1 are inapplicable, the Administrative Agent shall suspend the
availability of the Eurodollar Rate with respect to any Eurodollar Advances
made on or after the date of any such determination until such time as such
situation is no longer the case and shall require any outstanding Eurodollar
Advances to be repaid.

         6.3.       Funding Indemnification.  If any payment of a Eurodollar
Advance occurs on a date which is not the last day of the applicable Interest
Period, whether because of acceleration, prepayment, conversion or otherwise
(except pursuant to Section 6.2), or a Eurodollar Advance is not made on the
date specified by the Company for any reason other than default by the Lenders,
the Company will indemnify each Lender for any loss or cost incurred by it
resulting therefrom, including, without limitation, any loss or cost in
liquidating or employing deposits acquired to fund or maintain the Eurodollar
Advance (net of any cost or expense, unless Section 6.1, 6.5 or 6.6 is
applicable thereto, which the Lender would have incurred with respect to such
Eurodollar Advance had such prepayment or failure to fund not occurred).





                                       33
   40
         6.4.       Lending Installations.  Each Lender may book its Loans at
any Lending Installation selected by such Lender and may change its Lending
Installation from time to time.  All terms of this Agreement shall apply to any
such Lending Installation and the Notes shall be deemed held by each Lender for
the benefit of such Lending Installation.  Each Lender may, by written or telex
or facsimile notice to the Administrative Agent and the Company, designate a
Lending Installation through which Loans will be made by it and for whose
account Loan payments are to be made.  To the extent reasonably possible, each
Lender shall designate an alternate Lending Installation with respect to its
Eurodollar Loans to reduce any liability of the Company to such Lender under
Sections 6.1, 6.5 and 6.6 or to avoid the unavailability of a Rate Option under
Section 6.2, so long as such designation is not disadvantageous to such Lender
in the sole opinion of such Lender.

         6.5.       Increased Capital Costs.  If any change in, or the
introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in of, any law or regulation, directive, guideline, decision or request
(whether or not having the force of law) of any court, central bank, regulator
or other governmental authority affects or would affect the amount of capital
required or expected to be maintained by any Lender or any Person controlling
such Lender, and such Lender determines (in its sole and absolute discretion)
that the rate of return on its or such controlling Person's capital as a
consequence of its Commitments or the Loans made by such Lender is reduced to a
level below that which such Lender, or such controlling Person, as the case may
be, could have achieved but for the occurrence of any such circumstance (taking
into account such Person's policies as to capital adequacy), then, in any such
case upon notice from time to time by such Lender to the Company, the Company
shall immediately pay directly to such Lender additional amounts sufficient to
compensate such Lender or such controlling Person for such reduction in rate of
return.  A statement of such Lender as to any such additional amount or amounts
(including calculations thereof in reasonable detail) shall, in the absence of
manifest error, be conclusive and binding on the Company.  In determining such
amount, such Lender may use any method of averaging and attribution that it (in
its sole and absolute discretion) shall deem applicable.

         6.6.       Taxes.  All payments by the Company and MW Petroleum of
principal of, and interest on, the Loans and all other amounts payable
hereunder and in connection herewith shall be made free and clear of and
without deduction for any present or future income, excise, stamp or franchise
taxes and other taxes, fees, duties, withholdings or other charges of any
nature whatsoever imposed by any taxing authority, but excluding franchise
taxes and taxes imposed on or measured by any Agent's or any Lender's, as
applicable, net income or receipts (such non-excluded items being called
"Taxes").  In the event that any withholding or deduction from any payment to
be made by the Company or MW Petroleum hereunder or under any Loan Document is
required in respect of any Taxes pursuant to any applicable law, rule or
regulation, then the Company will

                    (a)      pay directly to the relevant authority the full
         amount required to be so withheld or deducted;

                    (b)      promptly forward to the Administrative Agent an
         official receipt or other documentation satisfactory to the
         Administrative Agent or the relevant Agent or Lender evidencing such
         payment to such authority; and

                    (c)      pay to the Administrative Agent for the account of
         the Agents and the Lenders such additional amount or amounts as is
         necessary to ensure that the net amount actually received by each
         Agent and Lender will equal the full amount such Agent or Lender would
         have received had no such withholding or deduction been required.

Moreover, if any Taxes are directly asserted against any Agent or any Lender,
with respect to any payment received by it hereunder or in connection herewith,
the relevant Agent or Lender may pay such Taxes and the Company will promptly
pay such additional amounts (including any penalties, interest or expenses) as
is necessary in order that the net amount received by such Person after the
payment





                                       34
   41
of such Taxes (including any Taxes on such additional amount) shall equal the
amount such Person would have received had not such Taxes been asserted.

         If the Company fails to pay any Taxes when due to the appropriate
taxing authority or fails to remit to the Administrative Agent, for the account
of the respective Agents and Lenders, the required receipts or other required
documentary evidence, the Company shall indemnify the Agents and the Lenders
for any incremental Taxes, interest or penalties that may become payable by any
Agent or Lender as a result of any such failure.  For purposes of this Section
6.6, a distribution hereunder by the Administrative Agent or any other Agent or
any Lender to or for the account of any Agent or Lender shall be deemed a
payment by the Company.

         Notwithstanding the foregoing, if any Agent or any Lender not
incorporated or organized under the laws of the United States of America, or a
state thereof, fails to timely deliver the forms required to be delivered
pursuant to Section 6.8 in a situation in which timely delivery of such forms
would eliminate some or all requirements for withholding of United States
federal income taxes by the Company or MW Petroleum in connection with payments
under this Agreement or the other Loan Documents, then the Company shall not be
required to pay or reimburse to the Lender or Agent any amount in respect of
such Taxes withheld that would not have been required to be withheld if such
Lender or Agent had timely delivered such forms.

         6.7.       Lender Statements; Survival of Indemnity; Substitution of
Lenders; Limitation on Claims by Lenders.  Each Agent and Lender shall deliver
to the Company and the Administrative Agent a written statement of such Agent
or Lender, as the case may be, as to the amount due, if any, under Sections
6.1, 6.3, 6.5 or 6.6.  Such written statement shall set forth in reasonable
detail the calculations upon which such Agent or Lender, as the case may be,
determined such amount and shall be final, conclusive and binding on the
Company in the absence of manifest error.  Determination of amounts payable
under such Sections in connection with a Eurodollar Loan shall be calculated as
though each Lender funded its Eurodollar Loan through the purchase of a deposit
of the type and maturity corresponding to the deposit used as a reference in
determining the Eurodollar Rate applicable to such Loan, whether in fact that
is the case or not.  Unless otherwise provided herein, the amount specified in
the written statement shall be payable on demand after receipt by the Company
of the written statement.  The obligations of the Company under Sections 6.1,
6.3, 6.5 and 6.6 shall survive payment of the Obligations and termination of
this Agreement.  In the event that any Lender shall deliver to the Company and
the Administrative Agent a written statement as to an amount due under Section
6.1, 6.3, 6.5 or 6.6, the Company may, at its sole expense and effort, require
such Lender to transfer and assign, without recourse (in accordance with
Section 17.3) all of its interests, rights and obligations under this Agreement
to an assignee which shall assume such assigned obligations (which assignee may
be another Lender, if a Lender accepts such assignment); provided that (i) such
assignment shall not conflict with any law, rule or regulation or order of any
court or other governmental authority, (ii) the Company shall have received a
written consent of the Administrative Agent and the Co-Agent in the case of an
entity that is not a Lender, which consent shall not be unreasonably withheld,
(iii) the Company or such assignee shall have paid to the assigning Lender in
immediately available funds the principal of and interest accrued to the date
of such payment on the Loans made by it hereunder and all other amounts owed to
it hereunder and the fee payable to the Administrative Agent pursuant to
Section 17.3(b) and (iv) that nothing in the foregoing is intended or shall be
construed as obligating any Lender to locate such an assignee.  The Company
shall not be required to pay to any Lender any amount under Section 6.1, 6.3,
6.5, or 6.6 in respect of any time or period more than twelve months prior to
the time such Lender notifies or bills the Company of or for such amount.

         6.8.       Withholding Tax Exemption.  At least five (5) Business Days
prior to the first date on which interest or fees are payable hereunder (but in
no event prior to the Effective Date) for the account of any Lender or any
Agent, each Lender or Agent that is not incorporated or organized under the
laws of the United States of America, or a state thereof, agrees that it will
deliver to each





                                       35
   42
of the Company and the Administrative Agent two (2) duly completed copies of
United States Internal Revenue Service Form 1001 or 4224, certifying in either
case that such Lender or Agent, as the case may be, is entitled to receive
payments under this Agreement and the Notes without deduction or withholding of
any United States federal income taxes.  Each Lender or Agent which so delivers
a Form 1001 or 4224 further undertakes to deliver to each of the Company and
the Administrative Agent two (2) additional copies of such form (or a successor
form) on or before the date that such form expires (currently, three (3)
successive calendar years for Form 1001 and one (1) calendar year for Form
4224) or becomes obsolete or after the occurrence of any event requiring a
change in the most recent forms so delivered by it, and such amendments thereto
or extensions or renewals thereof as may be reasonably requested by the Company
or the Administrative Agent, in each case certifying that such Lender or Agent,
as the case may be, is entitled to receive payments under this Agreement and
the Notes without deduction or withholding of any United States federal income
taxes, unless an event (including without limitation any change in treaty, law
or regulation) has occurred prior to the date on which any such delivery would
otherwise be required which renders all such forms inapplicable or which would
prevent such Lender or Agent from duly completing and delivering any such form
with respect to it and such Lender or Agent, as the case may be, advises the
Company and the Administrative Agent that it is not capable of receiving
payments without any deduction or withholding of United States federal income
tax.

                                  ARTICLE VIII

                         REPRESENTATIONS AND WARRANTIES

         The Company represents and warrants to the Lenders and the Agents that:

         8.1.       Corporate Existence and Standing.  The Company is a
corporation, and each Subsidiary is a corporation or other legal entity, in
either case duly incorporated or otherwise properly organized, validly existing
and in good standing under the laws of its jurisdiction of incorporation or
organization and has all requisite authority, permits and approvals, and is in
good standing to conduct its business in each jurisdiction in which its
business is conducted.

         8.2.       Authorization and Validity.  The Company and each
Subsidiary has the corporate or partnership power and authority and legal right
to execute and deliver the Loan Documents and to perform its respective
obligations thereunder.  The execution and delivery by the Company and each
Subsidiary of the Loan Documents to which it is a party and the performance of
its obligations thereunder have been duly authorized by proper corporate or
partnership proceedings, and the Loan Documents have been duly executed and
delivered and constitute legal, valid and binding obligations of the Company
and each Subsidiary enforceable against the Company and each Subsidiary in
accordance with their terms, except as enforceability may be limited by
bankruptcy, insolvency or similar laws affecting the enforcement of creditors'
rights generally.

         8.3.       No Conflict; Government Consent.  Neither the execution and
delivery by the Company and each Subsidiary of the Loan Documents nor the
consummation of the transactions therein contemplated, nor compliance with the
provisions thereof will violate any law, rule, regulation, order, writ,
judgment, injunction, decree or award binding on the Company or any Subsidiary
or the Company's or any Subsidiary's articles of incorporation or by-laws or
partnership agreement or the provisions of any indenture, instrument or
agreement to which the Company or any Subsidiary is a party or is subject, or
by which it, or its property, is bound, or conflict with or constitute a
default thereunder, or result in the creation or imposition of any Lien in, of
or on all or any part of the property of the Company or any Subsidiary.  No
order, consent, approval, license, authorization, or validation of, or filing,
recording or registration with, or exemption by, any governmental or public
body or authority, or any subdivision thereof, is required to authorize, or is
required in connection with the execution, delivery and performance of, or the
legality, validity, binding effect or enforceability of, any of the Loan
Documents.

         8.4.       Financial Statements.  The consolidated financial
statements of the Company dated December 31, 1993 heretofore delivered to the
Lenders were prepared in accordance with generally accepted accounting
principles in effect on the date such statements were prepared and fairly
present the consolidated financial condition of the Company and the
Subsidiaries at such date and the consolidated results of their operations for
the period then ended.

         8.5.       Material Adverse Change.  Since December 31, 1993, there
has been no change in the business, assets, properties, operations, condition
(financial or otherwise) or results of operations or prospects of the Company
and its Subsidiaries or MW Petroleum and its Subsidiaries or any legal or
regulatory development which could have or be a Material Adverse Effect.

         8.6.       Taxes.  The Company and the Subsidiaries have filed all
United States federal tax returns and all other tax returns which are required
to be filed and have paid all taxes due pursuant to said returns or pursuant to
any





                                       38
   45
assessment received by the Company or any Subsidiary, except such taxes, if
any, as are being contested in good faith and as to which adequate reserves
have been provided.  The United States income tax returns of the Company and
the Subsidiaries (other than MW Petroleum and MWJR) have been audited by the
Internal Revenue Service or, if no audit was performed, the statute of
limitations permitting such an audit has run, through the fiscal year ended
December 31, 1982.  No tax liens have been filed and no claims are being
asserted with respect to any such taxes.  The charges, accruals and reserves on
the books of the Company and the Subsidiaries in respect of any taxes or other
governmental charges are adequate.

         8.7.       Litigation and Contingent Obligations.  There is no
litigation, arbitration, governmental investigation, proceeding or inquiry
pending or, to the knowledge of any of their officers, threatened against or
affecting the Company or any Subsidiary which is or could have a Material
Adverse Effect.  The Company and its Subsidiaries have no material contingent
obligations not provided for or disclosed in the financial statements referred
to in Section 8.4.

         8.8.       Subsidiaries.  Schedule 8.8 hereto contains an accurate
list of all of the presently existing Subsidiaries of the Company as of the
date of this Agreement, setting forth their respective jurisdictions of
incorporation or organization and the percentage of their respective capital
stock or, the revenue share attributable to the general and limited partnership
interests, as the case may be, owned by the Company or other Subsidiaries.  All
of the issued and outstanding shares of capital stock of such Subsidiaries
which are corporations have been duly authorized and issued and are fully paid
and non-assessable.

         8.9.       ERISA.  The Unfunded Liabilities of all Plans do not in the
aggregate exceed $5,000,000.  Each Plan complies in all material respects with
all applicable requirements of law and regulations, no Reportable Event has
occurred with respect to any Plan, neither the Company nor any other members of
the Controlled Group has withdrawn from any Plan or initiated steps to do so,
and no steps have been taken to terminate any Plan.

         8.10.      Accuracy of Information.  No information, exhibit or report
furnished by the Company or any Subsidiary to any Agent or to any Lender in
connection with the negotiation of, or compliance with, the Loan Documents
contained any material misstatement of fact or omitted to state a material fact
or any fact necessary to make the statements contained therein not misleading.

         8.11.      Regulation-U.  Margin stock (as defined in Regulation U)
constitutes less than 25% of those assets of the Company and the Subsidiaries
which are subject to any limitation on sale, pledge, or other restriction
hereunder.

         8.12.      Material Agreements.  Neither the Company nor any
Subsidiary is in default in the performance, observance or fulfillment of any
of the obligations, covenants or conditions contained in (i) any agreement to
which it is a party, which default might have a Material Adverse Effect or (ii)
any agreement or instrument evidencing or governing Indebtedness.

         8.13.      Compliance With Laws.  The Company and the Subsidiaries
have complied in all material respects with all applicable statutes, rules,
regulations, orders and restrictions of any domestic or foreign government or
any instrumentality or agency thereof, having jurisdiction over the conduct of
their respective businesses or the ownership of their respective Properties.
Neither the Company nor any of the Subsidiaries has received any notice to the
effect that it, its operations or the Properties are not in material compliance
with any of the requirements of applicable federal, state or local
environmental, health and safety statutes and regulations, or are the subject
of any federal or state investigation evaluating whether any remedial action is
needed to respond to a release of any toxic or hazardous waste or substance
into the environment, whether from the Properties or elsewhere, which in any
case would have a Material Adverse Effect.





                                       39
   46
         8.14.      Title to Properties.  Each of the Company and the
Subsidiaries has legal, valid and defensible title to substantially all of its
properties and assets and valid and defensible title, whether legal or
beneficial, to all of its properties and assets, free and clear of any and all
Liens other than those Liens permitted by Section 11.5.  The 1994 Engineers'
Report refers to and covers all of the reserves in the Properties as of the
Effective Date and such Report covers no reserves other than in such
Properties.

         8.15.      Investment Company Act.  Neither the Company nor any
Subsidiary is an "investment company" or a company "controlled" by an
"investment company", within the meaning of the Investment Company Act of 1940,
as amended.

Holding Company Act of 1935, as amended.

         8.17.      Subordinated Indebtedness.  The Obligations constitute
senior indebtedness which is entitled to the benefits of the subordination
provisions of all outstanding Subordinated Indebtedness.

         8.18.      Post-Retirement Benefits.  The present value of the
expected cost of post-retirement medical and insurance benefits payable by the
Company and its Subsidiaries to its employees and former employees, as
estimated by the Company in accordance with reasonable procedures and
assumptions deemed reasonable by the Required Lenders, does not exceed
$2,000,000.

         8.19.      Solvency.  As of the Effective Date, (i) the Company and
its Consolidated Subsidiaries are each solvent and (ii) International and its
Subsidiaries on a consolidated basis is solvent.

         8.20.      Environmental Warranties.  In the ordinary course of its
business, the Borrower conducts an ongoing review of the effect of
Environmental Laws on the business, operations and Properties of the Borrower
and its Subsidiaries, in the course of which it identifies and evaluates
associated liabilities and costs (including any capital or operating
expenditures required for clean-up or closure of Properties presently owned or
operated, any capital or operating expenditures required to achieve or maintain
compliance with environmental protection standards imposed by law or as a
condition of any license, permit or contract, any related constraints on
operating activities, including any periodic or permanent shutdown of any
facility or reduction in the level of or change in the nature of operations
conducted thereat and any actual or potential liabilities to third parties,
including employees, and any related costs and expenses).  On the basis of this
review, the Borrower has reasonably concluded that, except as disclosed in
writing by the Company to the Lenders and the Agents, to the best of its
knowledge after due inquiry:

                    (a)      all facilities and property (including underlying
         groundwater) owned, leased or operated by the Company or any
         Subsidiary have been, and continue to be, owned, leased or operated by
         the Company or any Subsidiary in material compliance with all
         Environmental Laws;

                    (b)      there have been no past, and there are no pending 
         or threatened

                             (i)        claims, complaints, notices or
                    inquiries to, or requests for information received by, the

                    violation of any Environmental Law, that, singly or in the
                    aggregate, have or may reasonably be expected to have a
                    Material Adverse Effect, or

                             (ii)       claims, complaints, notices or
                    inquiries to, or requests for information received by, the
                    Company or any Subsidiary regarding potential liability
                    under any Environmental Law or under any common law
                    theories relating to operations or the

   47
                    condition of any facilities or property (including
                    underlying groundwater) owned, leased or operated by the
                    Company or any Subsidiary that, singly or in the aggregate,

         Company or any Subsidiary that, singly or in the aggregate, have, or
         may reasonably be expected to have, a Material Adverse Effect;

                    (d)      the Company and each Subsidiary have been issued
         and are in material compliance with all permits, certificates,
         approvals, licenses and other authorizations relating to environmental
         matters and necessary or desirable for their businesses;

         Indebtedness) in excess of $25,000,000 in aggregate principal amount
         when due or any such Indebtedness of an Affiliate shall be declared to
         be due and payable or required to be prepaid (other than a regularly
         scheduled payment) prior to the stated maturity thereof; or an
         Affiliate shall not pay, or shall admit in writing its inability to
         pay, its debts as they become due; if any of the foregoing would have
         a Material Adverse Effect.

             ACCELERATION, WAIVERS, AMENDMENTS, REMEDIES; RELEASES

         13.1.      Acceleration.  If any Default described in Section 12.7 or
12.8 occurs with respect to the Company, (a) the obligations of the Lenders to
make Loans hereunder shall automatically terminate, (b) the Obligations shall
immediately become due and payable without any election or action on the part
of any Agent or any Lender and without presentment, demand, protest or notice
of any kind, including without notice of acceleration or notice of intent to
accelerate, all of which the Company and MW Petroleum each hereby expressly
waives, and (c) the Agents and the Lenders and each of them shall be able to
exercise any rights available to it or them under the Loan Documents, the
Guaranty or by law.  If any other Default occurs, (a) the Required Lenders may
terminate or suspend the obligations of the Lenders to make Loans hereunder, or
declare the Obligations to be due and payable, or both, whereupon the
Obligations shall become immediately due and payable, without presentment,
demand, protest or notice of any kind, including without notice of acceleration
or notice of intent to accelerate, all of which the Company and MW Petroleum
each hereby expressly waives, and (b) the Agents and the Lenders and each of
them shall be able to exercise any rights available to it or them under the
Loan Documents, the Guaranty or by law.  The Administrative Agent hereby
agrees, at the written direction of the Required Lenders, subject to the
provisions of Article XV, to exercise any of the foregoing rights available to
it.

         13.2.      Amendments.  Subject to the provisions of this Article
XIII, the Required Lenders (or the Administrative Agent with the consent in
writing of the Required Lenders) and the Company may enter into agreements
supplemental hereto for the purpose of adding or edifying any provisions to the
Loan Documents or changing in any manner the rights and remedies of the Lenders
or the Company hereunder or waiving any Default hereunder; provided however
that Sections 2.3 and the related definitions in Section 1.1 shall not be
changed without the prior written consent of the Required Lenders; provided,
further however, that no such supplemental agreement shall, without the consent
of each Lender affected thereby:

                    (a)      Extend the maturity of any Loan, Note or payment
         under a Guaranty, or reduce the principal amount of any of them, or
         reduce the rate or extend the time of payment of interest or fees
         thereon.





                                       54
   61
                    (b)      Reduce the percentage specified in the definition
         of Required Lenders.

                    (c)      Extend the Termination Date or reduce the amount
         or extend the payment date for, the mandatory payments required under
         Section 4.2 or increase the amount of the Commitment of any Lender
         hereunder or permit the Company to assign its rights or obligations
         under this Agreement or under any other Loan Document.

                    (d)      Amend this Section 13.2.

No amendment of any provision of this Agreement relating to any Agent shall be
effective without the written consent of such Agent.  The Administrative Agent
may waive payment of the fee required under Section 17.3(b) without obtaining
the consent of any of the Lenders.

         13.3.      Preservation of Rights.  All remedies contained in the Loan
Documents or afforded by law shall be cumulative and all shall be available to
the Agents and the Lenders until the Obligations have been paid in full.  No
delay or omission of the Lenders, the Agents or any of them to exercise any
right under the Loan Documents shall impair such right or be construed to be a
waiver of any Default or an acquiescence therein, and the making of a Loan
notwithstanding the existence of a Default or the inability of the Company to
satisfy the conditions precedent to such Loan shall not constitute any waiver
or acquiescence.  Any single or partial exercise of any such right shall not
preclude other or further exercise thereof or the exercise of any other right,
and no waiver, amendment or other variation of the terms, conditions or
provisions of the Loan Documents whatsoever shall be valid unless in writing
signed by the Lenders and the Agents required pursuant to Section 13.2, and
then only to the extent specifically set forth in such writing.
Notwithstanding the foregoing or any other provision of this Agreement, each of
the various written consents provided by the Administrative Agent on behalf of
the Lenders, or any group of Lenders, with respect to the April 1992 Agreement
shall remain in full force and effect according to its terms, including,
without limitation, each consent contained in that certain letter from the
Administrative Agent to the Company dated January 20, 1994, concerning the
purchase by the Company of up to five million shares of its common stock.

         13.4.      Rights and Remedies Upon Classification as a Highly
Leveraged Transaction.  If any Agent shall determine or be advised by the Board
of Governors of the Federal Reserve System, the Federal Deposit Insurance
Corporation or the Office of the Comptroller of the Currency or any other
applicable regulatory agency (including any successor agency) or examiner, that
the facilities available under this Agreement and the other Loan Documents, or
any Advance, or any Note constitute a "highly leveraged transaction", as such
term may be defined or interpreted, in accordance with applicable federal
guidelines and regulations as in effect from time to time, such Agent shall
promptly notify the Administrative Agent and the Administrative Agent shall
promptly notify the Company, the other Agents and the Lenders (an "HLT
Notice").  If an HLT Notice shall be given, the Company shall forthwith
commence discussions with the Administrative Agent to attempt to negotiate
revisions to this Agreement and the other Loan Documents (including, without
limitation, a restructuring of the facilities and the Commitments, or an
increase in the interest rates, margins, and fees, and changes in the terms,
covenants, representations and any other terms deemed relevant by the Lenders
and the Agents in their sole and absolute discretion).  Any such revisions
shall be subject to the approval of all the Agents and all the Lenders and
nothing herein contained shall obligate the Company, the Lenders or the Agents
to agree to any such revisions.

         13.5.      Release of Collateral.  Each Agent and each Lender agrees
that the Collateral Agent is authorized and directed to (a) release the
security interest granted to the Collateral Agent pursuant to the Partnership
Pledge and Security Agreement, the Stock Pledge and Security Agreement, the
Security Agreement and Financing Statement and the MW Petroleum Stock Pledge,
(b) terminate any intercreditor agreement or other agreement relating to the
maintenance or disposition of collateral for Loans under the April 1992
Agreement, (c) terminate





                                       55
   62
any and all financing statements filed with respect to any of the foregoing
instruments and (d) return to the Company or MW Petroleum, as applicable, all
stock certificates representing collateral.

                                  ARTICLE XIV

                               GENERAL PROVISIONS

         14.1.      Survival of Representations.  All representations and
warranties of the Company, MW Petroleum and any other Subsidiary contained in
the July 1991 Agreement, the April 1992 Agreement, this Agreement, or in any
other Loan Document shall survive the delivery of the Notes and the making of
the Loans herein contemplated until all the Obligations have been paid and this
Agreement has been terminated.

         14.2.      Governmental Regulation.  Anything contained in this
Agreement to the contrary notwithstanding, no Lender shall be obligated to
extend credit to the Company in violation of any limitation or prohibition
provided by any applicable statute or regulation.

         14.3.      Taxes.  Any taxes (excluding income taxes) or other similar
assessments or charges payable or ruled payable by any governmental authority
in respect of the Loan Documents shall be paid by the Company, together with
interest and penalties, if any.

         14.4.      Headings.  Article and section headings in the Loan
Documents are for convenience of reference only, and shall not govern the
interpretation of any of the provisions of the Loan Documents.

         14.5.      Entire Agreement.  The Loan Documents embody the entire
agreement and understanding among the Company, the Agents and the Lenders and
supersede all prior agreements and understandings among the Company, the Agents
and the Lenders relating to the subject matter thereof.

         14.6.      Several Obligations.  The respective obligations of the
Lenders hereunder are several and not joint and no Lender shall be the partner
or agent of any other (except to the extent to which an Agent is authorized to
act as such).  The failure of any Lender to perform any of its obligations
hereunder shall not relieve any other Lender from any of its obligations
hereunder.  This Agreement is not intended to, and shall not be construed so as
to, confer any right or benefit upon any Person other than the parties to this
Agreement and their respective successors and assigns.

         14.7.      Reimbursement of Costs and Expenses; Indemnification.

                    (a)      Reimbursement of Costs and Expenses.  The Company
         shall reimburse each Agent for any reasonable costs, internal charges
         and out-of-pocket expenses (including fees and expenses of consultants
         and attorneys' fees and time charges of attorneys for such Agent,
         which attorneys may be employees of such Agent) paid or incurred by
         such Agent in connection with (i) the preparation, review, execution,
         delivery, amendment, modification and administration of the Loan
         Documents including, without limitation, the fees incurred by such
         Agent in connection with its initial evaluation of the Properties and
         costs, charges and expenses incurred in connection with the
         negotiation and documentation of revisions pursuant to Section 13.4,
         and (ii) the filing, recordation, refiling or re-recording or
         termination of the Collateral Documents and/or any Uniform Commercial
         Code financing statements relating thereto and any and all other
         documents or instruments or further assurances required to be filed or
         recorded or refiled or re-recorded or terminated by the terms of this
         Agreement or the Collateral Documents.  The Company shall reimburse
         each Agent and the Lenders for any costs, internal charges and
         out-of-pocket expenses (including attorneys' fees and time charges of
         attorneys for the Agent and the Lenders, which attorneys may be
         employees of the Agents or the Lenders) paid or incurred by any





                                       56
   63
         Agent or any Lender in connection with the collection and enforcement
         of the Loan Documents.

                    (b)      Indemnification.  In consideration of the
         execution and delivery of this Agreement by each Lender and the
         extension of the Commitments, the Company hereby indemnifies,
         exonerates and holds each Agent and each Lender, and their respective
         directors, Agents, officers and employees ("Indemnified Persons") free
         and harmless from and against any and all losses, claims, damages,
         penalties, judgments, liabilities, actions, suits, costs and expenses
         (including, without limitation, all expenses of litigation or
         preparation therefor whether or not any Agent or any Lender or any
         Indemnified Person is a party thereto and all other attorneys' fees
         and disbursements) ("Claims") which any of them may pay or incur as a
         result of, arising out of, or relating to,

                             (i)        this Agreement, the other Loan
                    Documents, the transactions contemplated hereby or thereby;

                             (ii)       the direct or indirect application or
                    proposed application of the proceeds of any Loan hereunder;

                             (iii)      any transaction financed or to be
                    financed in whole or in part, directly or indirectly, with
                    the proceeds of any Loan;

                             (iv)       any investigation, litigation or
                    proceeding related to any acquisition or proposed
                    acquisition by the Company, any of its Subsidiaries, HERC
                    or HEL of all or any portion of the stock or assets of any
                    Person, whether or not any Agent or any Lender is party
                    thereto;

                             (v)        any investigation, litigation or
                    proceeding related to any environmental cleanup, audit,
                    compliance or other matter relating to any Environmental
                    Law or the condition of any facility or property owned,
                    leased or operated by the Company or any Subsidiary;

                             (vi)       the presence on or under, or the
                    escape, seepage, leakage, spillage, discharge, emission,
                    discharging or releases from, any facility or property
                    owned, leased or operated by the Company or any Subsidiary
                    thereof of any Hazardous Material (including any losses,
                    liabilities, damages, injuries, costs, expenses or claims
                    asserted or arising under any Environmental Law),
                    regardless of whether caused by, or within the control of,
                    the Company or such Subsidiary; or

                             (vii)      any misrepresentation, inaccuracy or 
                    any breach in or of Section 8.20 or Section 9.12;

(the foregoing collectively the "Indemnified Liabilities"), except to the
extent that a final order of a court of competent jurisdiction finds that the
such Indemnified Liability arises solely from such Indemnified Person's gross
negligence or wilful misconduct.  If and to the extent that the foregoing
undertaking may be unenforceable for any reason, the Company hereby agrees to
make the maximum contribution to the payment and satisfaction of each of the
Indemnified Liabilities which is permissible under applicable law.  The
obligations of the Company under this Section 14.7 shall survive the
termination of this Agreement or any non- assumption of this Agreement in a
bankruptcy or similar proceeding.  The Company shall be obligated to indemnify
the Indemnified Persons for all Claims regardless of whether the Company had
knowledge of the facts and circumstances giving rise to such Claims.

         14.8.      Numbers of Documents.  All statements, notices, closing
documents, and requests hereunder shall be furnished to the Administrative

   64
         14.9.      Severability of Provisions.  Any provision in any Loan
Document that is held to be inoperative, unenforceable, or invalid in any
jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable, or
invalid without affecting the remaining provisions in that jurisdiction or the
operation, enforceability, or validity of that provision in any other
jurisdiction, and to this end the provisions of all Loan Documents are declared
to be severable.

         14.10.     Nonliability of Lenders.  The relationship between the
Company on the one hand and the Lenders and the Agents on the other hand shall
be solely that of borrower and lender.  None of the Agents nor any Lender shall
have any fiduciary responsibilities to the Company or any of its Subsidiaries.
None of the Agents nor any Lender undertakes any responsibility to the Company
or any of its Subsidiaries to review or inform the Company of any matter in
connection with any phase of the Company's or such Subsidiary's business or
operations.

         14.11.     CHOICE OF LAW.  THE LOAN DOCUMENTS (OTHER THAN THOSE
CONTAINING A CONTRARY EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS (AND NOT THE LAW OF CONFLICTS) OF THE STATE
OF ILLINOIS, BUT GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL LENDERS.

         14.12.     CONSENT TO JURISDICTION.  ANY LITIGATION BASED HEREON, OR
ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN
DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER
VERBAL OR WRITTEN) OR ACTIONS OF ANY AGENT, THE LENDERS OR THE COMPANY SHALL BE
BROUGHT AND MAINTAINED EXCLUSIVELY IN THE COURTS OF THE STATE OF ILLINOIS OR IN
THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS;
PROVIDED, HOWEVER, THAT ANY SUIT SEEKING ENFORCEMENT AGAINST ANY COLLATERAL OR
OTHER PROPERTY MAY BE BROUGHT, AT ANY AGENT'S OPTION, IN THE COURTS OF ANY
JURISDICTION WHERE SUCH COLLATERAL OR OTHER PROPERTY MAY BE FOUND.  THE COMPANY
HEREBY EXPRESSLY AND IRREVOCABLY SUBMITS TO THE JURISDICTION OF THE COURTS OF
THE STATE OF ILLINOIS AND THE UNITED STATES DISTRICT COURT FOR THE NORTHERN
DISTRICT OF ILLINOIS FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE
AND IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN
CONNECTION WITH SUCH LITIGATION.  THE COMPANY FURTHER IRREVOCABLY CONSENTS TO
THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL
SERVICE WITHIN OR WITHOUT THE STATE OF ILLINOIS.  THE COMPANY HEREBY EXPRESSLY
AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION
WHICH IT MAY HAVE OR HEREAFTER MAY HAVE TO THE LAYING OF VENUE OF ANY SUCH
LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY
SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.  TO THE EXTENT THAT
THE COMPANY HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY
COURT OF FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT
PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO
ITSELF OR ITS PROPERTY, THE COMPANY HEREBY IRREVOCABLY WAIVES SUCH IMMUNITY IN
RESPECT OF ITS OBLIGATIONS UNDER THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

         14.13.     Confidentiality.  Each Lender and each Agent agrees to hold
any confidential information which it may receive from the Company pursuant to
this Agreement in confidence in accordance with the provisions set forth in
Exhibit "J" hereto.  In addition to the disclosures permitted in such
provisions, the Lenders and the Agents each shall be permitted to make
disclosures of such information in accordance with Section 17.4.

by such Agent.

         15.3.      General Immunity.  No Agent nor any of their directors,

order of a court of competent jurisdiction.

         15.4.      No Responsibility for Loans, Recitals, etc.  No Agent nor
any of their directors, officers, agents or employees shall be responsible for

warranty or representation made in connection with any Loan Document or any
borrowing hereunder; (ii) the performance or observance of any of the covenants
or agreements of any obligor under any Loan Document; (iii) the satisfaction of
any condition specified in Article VII, except receipt by an Agent of items
required to be delivered to such Agent unless such condition shall have been
waived in accordance with Section 13.2; or (iv) the validity, effectiveness or
genuineness of any Loan Document or any other agreement, instrument or writing
furnished in connection therewith.

         15.5.      Action on Instructions of Lenders.  Each Agent shall in all
cases be fully protected in acting, or in refraining from acting, hereunder and
under any other Loan Document in accordance with written instructions signed by
the Required Lenders or the Required Lenders, as the case may be, and such
instructions and any action taken or failure to act pursuant thereto shall be
binding on all of the Lenders, the other Agents and all holders of Notes.

         15.6.      Employment of Agents and Counsel.  Each Agent may execute
any of its duties as Agent hereunder and under any other Loan Document by or
through employees, agents, and attorneys-in-fact and shall not be answerable to
the Lenders, except as to money or securities received by it or its authorized
agents, for the default or misconduct of any such agents or attorneys-in-fact
selected by it with reasonable care.  Each Agent shall be entitled to advice of
counsel concerning all matters pertaining to the agency hereby created and its
respective duties hereunder and under any other Loan Document.

         15.7.      Reliance on Documents; Counsel.  Each Agent shall be
entitled to rely upon any Note, notice, consent, certificate, affidavit,
letter, telegram, statement, paper or document believed by it to be genuine and
correct and to have been signed or sent by the proper person or persons, and,
in, respect to legal matters, upon the opinion of counsel selected by such
Agent, which counsel may be employees of the Agents or any of them.

         15.8.      Reimbursement and Indemnification.  Each Lender agrees to
reimburse and indemnify each of the Administrative Agent, the Collateral Agent,
the Co-Agent ratably in proportion to such Lender's Aggregate Commitments, (i)
for any amounts (other than principal or interest) not reimbursed by the
Company or the Guarantor for which such Agent is entitled to reimbursement by
the Company under the Loan Documents, and (ii) for any liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind and nature whatsoever which may be
imposed on, incurred by or asserted against such Agent in any way relating to
or arising out of the Loan Documents or any other document delivered in
connection therewith or the transactions contemplated thereby, or the
enforcement of any of the terms thereof or of any such other documents,
provided that no Lender shall be so liable to the extent any of the foregoing
is found by a final order of a court of competent





                                       59
   66
jurisdiction to have arisen solely from such Agent's gross negligence or
willful misconduct.

         15.9.      Rights as a Lender.  With respect to its Commitments, Loans
made by it and the Notes issued to it, each Agent shall have the same rights
and powers hereunder and under each other Loan Document as any Lender and may
exercise the same as though it did not hold such role, and the term "Lender" or
"Lenders" shall, unless the context otherwise indicates, include each of them
in its individual capacity.  In addition to, and not by way of limitation of
the rights set forth in Section 14.14, each Agent may accept deposits from,
lend money to, and generally engage in any kind of banking or trust business
with the Company or any Subsidiary or any other Affiliate of the Company as if
it did not hold such role.

         15.10.     Lender Credit Decision.  Each Lender acknowledges that it
has, independently and without reliance upon any Agent or any other Lender and
based on the financial statements prepared by the Company and such other
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement and the other Loan
Documents.  Each Lender also acknowledges that it will, independently and
without reliance upon any Agent or any other Lender and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own credit decisions in taking or not taking action under this Agreement and
the other Loan Documents.

         15.11.     Certain Successor Agents.  Any Agent may resign at any time
by giving thirty (30) days' prior written notice thereof to the Lenders and the
Company.  Upon any such resignation, the Company shall, if no Default or
Unmatured Default has occurred and is continuing, have the right (subject to
the consent of the Required Lenders) to appoint, on behalf of the Company and
the Lenders, a Lender as a successor Agent.  If no successor Agent shall have
been so appointed by the Company and shall have accepted such appointment
within thirty (30) days' after the retiring Agent's giving notice of
resignation, then the retiring Agent may appoint, on behalf of the Company and
the Lenders, a Lender as a successor Agent; provided, however, that the Company
may, within the one year period following the appointment of a successor Agent,
and upon thirty (30) days written notice to the Lenders, remove the successor
Agent and appoint a successor Agent acceptable to the Company (subject to the
consent of the Required Lenders).  Upon the acceptance of any appointment as
Agent hereunder by a successor Agent, such successor Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Agent, and the retiring Agent shall be discharged from its
duties and Obligations (but not any liability arising from its gross negligence
or wilful misconduct as established by a final order of a court of competent
jurisdiction) hereunder and under the other Loan Documents.  After any retiring
Agent's resignation hereunder as Agent, the provisions of this Article XV shall
continue in effect for its benefit in respect of any actions taken or omitted
to be taken by it while it was acting as an Agent hereunder and under the other
Loan Documents.


                                  ARTICLE XVI

                            SETOFF; RATABLE PAYMENTS

         16.1.      Setoff.  In addition to, and without limitation of, any
rights of the Lenders under applicable law, if the Company becomes insolvent,
however evidenced, or any Default or Unmatured Default occurs, any indebtedness
from any Lender to the Company (including all account balances, whether
provisional or final and whether or not collected or available) may be offset
and applied toward the payment of the Obligations owing to such Lender, whether
or not the Obligations, or any part hereof, shall then be due and payable.

         16.2.      Ratable Payments.  If any Lender, whether by setoff or
otherwise, has payment made to it upon its Loans in a greater proportion than
it would have received pursuant to an allocation using the method set forth in
Section 4.3 or 4.4 (except for payments made to Lenders with respect to 1992
Revolving Loans which are outstanding on the Effective Date including, without
limitation,





                                       60
   67
payments made to Banque Indosuez and Norwest Bank Denver, N.A. pursuant to
Section 9.16), such Lender agrees, promptly upon demand, to purchase a portion
of the Loans held by the other Lenders so that after such purchase each Lender
will hold its ratable proportion of such type of Loans.  If any Lender, whether
in connection with setoff or amounts which might be subject to setoff or
otherwise, receives collateral or other protection for its Obligations or such
amounts which may be subject to set off, such Lender agrees, promptly upon
demand, to take such action necessary such that all Lenders share in the
benefits of such collateral ratably in proportion to the Obligations owing to
each of them.  In case any such payment is disturbed by legal process, or
otherwise, appropriate further adjustments shall be made.


                                  ARTICLE XVII

               BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

         17.1.      Successors and Assigns.  The terms and provisions of the
Loan Documents shall be binding upon and inure to the benefit of the Company,
the Agents and the Lenders and their respective successors and assigns, except
that the Company shall not have the right to assign its rights or obligations
under the Loan Documents and any assignment by any Lender must be made in
compliance with Section 17.3.  The Administrative Agent and the Collateral
Agent may treat the payee of any Note as the owner thereof for all purposes
hereof unless and until such payee complies with Section 17.3 in the case of an
assignment thereof or, in the case of any other transfer, a written notice of
the transfer is filed with such Agent.  Any assignee or transferee of a Note
agrees by acceptance thereof to be bound by all the terms and provisions of the
Loan Documents.  Any request, authority or consent of any Person, who at the
time of making such request or giving such authority or consent is the holder
of any Note, shall be conclusive and binding on any subsequent holder,
transferee or assignee of such Note or of any Note or Notes issued in exchange
therefor.

         17.2.      Participations.

                    (a)      Any Lender, in the ordinary course of its business
         and in accordance with applicable law, at any time may sell to one or
         more banks or other entities ("Participants") participating interests
         in any Loan owing to such Lender, any Note held by such Lender, any
         Commitment of such Lender or any other interest of such Lender under
         the Loan Documents.  In the event of any such sale by a Lender of
         participating interests to a Participant, such Lender's Obligations
         under the Loan Documents shall remain unchanged, such Lender shall
         remain solely responsible to the other parties hereto for the
         performance of such obligations, such Lender shall remain the holder
         of any such Note or Obligation for all purposes under the Loan
         Documents, and the Company and the Agents shall continue to deal
         solely and directly with such Lender in connection with such Lender's
         rights and obligations under the Loan Documents.

                    (b)      Each Lender shall retain the sole right to
         approve, without the consent of any Participant, any amendment,
         modification or waiver of any provision of the Loan Documents other
         than any amendment, modification or waiver with respect to any Loan or
         Commitment in which such Participant has an interest which forgives
         principal, interest or fees or reduces the interest rate or fees
         payable with respect to any such Loan or Commitment, postpones any
         date fixed for any regularly-scheduled payment of principal of, or
         interest or fees on, or reimbursement obligation with respect to, any
         such Loan or Commitment, releases any guarantor of any such Obligation
         or releases all or substantially all of the collateral (except as
         permitted by Section 13.2(d)), if any, securing any such Obligation.

                    (c)      The Company agrees that each Participant shall be
         deemed to have the right of setoff provided in Section 16.1 in respect
         of its participating interest in amounts owing under the Loan
         Documents to the same extent as if the amount of its participating
         interest were owing directly to it as a Lender under the Loan
         Documents, provided that each





                                       61
   68
         Lender shall retain the right of setoff provided in Section 16.1 with
         respect to the amount of participating interests sold to each
         Participant.  The Lenders agree to share with each Participant, and
         each Participant, by exercising the right of setoff provided in
         Section 16.1, agrees to share with each Lender, any amount received
         pursuant to the exercise of its right of setoff, such amounts to be
         shared in accordance with Section 16.2 as if each Participant were a
         Lender.  The Company also agrees that each Participant shall be
         entitled to the benefits of Sections 6.1 and 6.3 with respect to its
         participation in the Commitments or the Loans outstanding from time to
         time; provided, that no Participant shall be entitled to receive any
         greater amount pursuant to such Sections than the transferor Lender
         would have been entitled to receive in respect of the amount of the
         participation transferred by such transferor Lender to such
         Participant had no such transfer occurred.

         17.3.      Assignments.

                    (a)      Any Lender may, in the ordinary course of its
         business and in accordance with applicable law and with the consent of
         the Company, at any time assign to one or more banks or other entities
         ("Purchasers") all or any part of its rights and obligations under the
         Loan Documents subject to a minimum of $15,000,000 or such lesser
         amount as may be agreed to by the Company; provided that with respect
         to any Purchaser which is an Affiliate of such Lender, such consent of
         the Company shall not be unreasonably withheld.  Such assignment shall
         be substantially in the form of Exhibit "D" hereto.  The consent of
         the Administrative Agent shall also be required prior to an assignment
         becoming effective with respect to a Purchaser which is not a Lender.
         All such consents shall be substantially in the form attached as
         Exhibits "D-II" or "D- III" to Exhibit "D" hereto and shall not be
         unreasonably withheld.

                    (b)      Upon (i) delivery to the Administrative Agent of a
         notice of assignment, substantially in the form attached as Exhibit
         "D-I" to Exhibit "D" hereto (a "Notice of Assignment"), together with
         any consents required by Section 17.3.(a), and (ii) payment of a
         $2,500 fee to the Administrative Agent for processing such assignment,
         such assignment shall become effective on the effective date specified
         in such Notice of Assignment; provided, however, that any amounts paid
         by the Company to, or for the benefit of, the assigning Lender, on or
         before the execution date of the assignment, if such date is later
         than the effective date of the assignment, shall be deemed paid to and
         for the benefit of the Purchaser for all purposes.  On and after the
         effective date of such assignment, such Purchaser shall for all
         purposes be a Lender, party to this Agreement and any other Loan
         Document executed by the Lenders, and shall have all the rights and
         obligations of a Lender under the Loan Documents, to the same extent
         as if it were an original party hereto, and no further consent or
         action by the Company, the Lenders or any Agent shall be required to
         release the transferor Lender, with respect to the percentages of the
         Commitment, and the Loans assigned to such Purchaser and the
         transferor Lender shall henceforth be so released.  Upon the
         consummation of any assignment to a Purchaser pursuant to this Section
         17.3(b), the Company shall issue replacement Notes to such transferor
         Lender and shall issue new Notes or, as appropriate, replacement
         Notes, to such Purchaser, in each case in principal amounts reflecting
         their respective Commitments, as adjusted pursuant to such assignment.

                    (c)      The provisions of the foregoing clauses (a) and
         (b) shall not apply to or restrict, or require the consent of or
         notice to any Person to effectuate, the pledge or assignment by any
         Agent or Lender of its rights or obligations under any Loan Documents
         to any Federal Reserve Bank.

         17.4.      Dissemination of Information.  The Company authorizes each
Agent and each Lender to disclose to any Participant or Purchaser or any other
Person acquiring an interest in the Loan Documents by operation of law (each a
"Transferee") and any prospective Transferee any and all information in such





                                       62
   69
Lender's possession concerning the creditworthiness of the Company and the
Subsidiaries, provided that such Transferee and prospective Transferee agrees
in writing to be bound by Section 14.13 of this Agreement.

         17.5.      Tax Treatment.  If any interest in any Loan Document is
transferred to any Transferee which is organized under the laws of any
jurisdiction other than the United States or any State thereof, the transferor
Lender shall cause such Transferee, concurrently with the effectiveness of such
transfer, to comply with the provisions of Section 6.8.


                                 ARTICLE XVIII

                                    NOTICES

         18.1.      Giving Notice.  Except as otherwise permitted by Section
4.5 with respect to borrowing notices, all notices and other communications
provided to any party hereto under this Agreement or any other Loan Document
shall be in writing or by telex or by facsimile and addressed or delivered to
such party at its address set forth below its signature hereto or at such other
address as may be designated by such party in a notice to the other parties.
Any notice, if mailed and properly addressed with postage prepaid, shall be
deemed given when received; any notice, if transmitted by telex or facsimile,
shall be deemed given when transmitted (answerback confirmed in the case of
telexes).

         18.2.      Change of Address.  The Company, the Administrative Agent,
the Co-Agent, the Collateral Agent and the Lenders may each change the address
for service of notice upon it by a notice in writing to the other parties
hereto.


                                  ARTICLE XIX

                                  COUNTERPARTS

         This Agreement may be executed in any number of counterparts, all of
which taken together shall constitute one agreement, and any of the parties
hereto may execute this Agreement by signing any such counterpart.  This
Agreement shall be effective when it has been executed by the Company, the
Agents and the Lenders and each party has notified the Administrative Agent, by
telex, facsimile or telephone, that it has taken such action.


                                   ARTICLE XX

                               NO ORAL AGREEMENTS

         THIS WRITTEN AGREEMENT, THE NOTES, AND THE OTHER LOAN DOCUMENTS
REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED
BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE
PARTIES.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.

         IN WITNESS WHEREOF, the Company, the Lenders and the Agents have
executed this Agreement as of the date first above written.
