         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,
         as set forth in this Section 2.1(e) and Article III, at any time
         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.

         2.2.       Extension of Termination Date and of Commitment.

                    (a)      Subject to the other provisions of this Agreement,
         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 on the date which is
         one (1) year from the then scheduled Termination Date.  If the Company
         shall request in an Annual Certificate of Extension delivered to the
         Administrative Agent concurrently with delivery of the Approved
         Engineers' Report delivered prior to the then scheduled Termination
         Date pursuant to Section 9.1(d) that the Aggregate Commitment be
         extended for one year from the then scheduled Termination Date, then
         the Administrative Agent shall promptly notify each Lender of such
         request and each Lender shall notify the Administrative Agent, no
         later than the next date by which each Lender is required, pursuant to
         Section 2.3(a), to (i) approve or disapprove the Engineering Banks'
         determination of the Borrowing Base and (ii) 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





                                      21
   28
         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 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 and Aggregate Available Commitment.

                    (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 $765,000,000.  The Borrowing Base shall be redetermined upon
         receipt by the Administrative Agent, the Engineering Banks and the
         Lenders of the





                                      22
   29
         relevant Approved Engineers' Report or Company's Engineers' Report, as
         the case may be, pursuant to Sections 2.3(b) or (e) or 9.1(d), (e) or
         (f).  The redeterminations of the Borrowing Base described in the
         preceding sentence shall be made as follows:  The Engineering Banks
         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 the amount, if
         any, of the Non-conforming Borrowing Base and the resulting Aggregate
         Available Commitment.  Each Lender shall notify the Administrative
         Agent in writing, by telex or by facsimile transmission whether it
         approves or disapproves of any such determination 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 or
         the Aggregate Available Commitment, as the case may be, and the
         Administrative Agent shall within five (5) days of such approval
         notify the Company in writing of such redetermined Borrowing Base.
         The Administrative Agent shall promptly notify the Company and the
         Lenders of any change in the Borrowing Base.  Additionally, the
         Aggregate Available Commitment may or will be reduced from time to
         time as provided in Sections 2.3(d), (e) and (f), Section 4.2(d) and
         Section 11.1.

                    (b)      Determination of Borrowing Base at Request of
         Company.  The Company may request one Borrowing Base determination
         between any regularly scheduled semi-annual redeterminations of the
         Borrowing Base by delivery to the Administrative Agent, the
         Engineering Banks 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 Engineering Banks and the Lenders such
         reports and information concerning the Properties (which may include
         in the Engineering Banks' sole discretion an Approved Engineers'
         Report or a Company's Engineers' Report as of such date) as the
         Engineering Banks shall deem appropriate in its or their sole
         discretion.

                    (c)      Criteria for Determination of the Borrowing Base.
         Each determination by the Engineering Banks 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





                                      23
   30
                             (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 Engineering
         Banks 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 Engineering Banks 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 (i) in oil and/or gas prices,
         (ii) in taxes, (iii) in anticipated rates or amounts of production
         from any Properties included in the Borrowing Base, (iv) in the
         Company's or any Subsidiary's, as the case may be, title or purported
         title to the Properties, (v) in operating, lease, royalty and other
         arrangements relating to the Properties, (vi) in operating costs with
         respect to the Properties, or (vii) in the Company's anticipated
         revenues as a result of the Company or any of its Subsidiaries'
         granting a Lien upon any of its Properties securing Indebtedness
         permitted by Section 11.1(g) or incurring Indebtedness permitted by
         Section 11.1(g), then in any such event the Engineering Banks 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 Engineering Banks in their sole
         and absolute discretion.

                    (f)      Reduction of Aggregate Available Commitment 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 Aggregate Available
         Commitment 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 Aggregate Available Commitment 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.

         2.5.       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
                             rates per annum set forth in Schedule B 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
                             rates applicable per annum set forth in Schedule B
                             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 2.5(a)(ii).

         Facility fees accruing pursuant to this Section 2.5(a) shall be
         payable in arrears on each Payment Date hereafter and on the
         Termination Date.  In addition to the foregoing, the Company agrees to
         pay all fees accruing prior to date hereof with respect to each
         Lender's commitments under the April 1994 Agreement.

                    (b)      Agents' Fees.  The Company shall pay to each Agent
         for its own respective account such fees in connection with this
         Agreement as previously have been agreed in a writing among them (as
         such writing may hereafter be amended, supplemented, restated or
         otherwise modified and in effect).

         3.2.       [Intentionally Omitted.]

         3.3.       Method of Selecting Rate Options and Interest Periods for
Revolving Loans.  The Company shall select the Rate Option and Interest Period

the Administrative Agent irrevocable notice (a "Borrowing Notice") not later
than (a) 10:00 a.m. Chicago time on the Borrowing Date of each Floating Rate
Revolving Advance, and (b) 11:00 a.m. Chicago time at least three (3) Business
Days before the Borrowing Date for each Eurodollar Revolving Advance,
specifying:

                             (i)        the Borrowing Date, which shall be a
                    Business Day, of such Revolving Advance,

                             (ii)       the aggregate amount of such Revolving
                    Advance,

                             (iii)      the Rate Option selected for such
                    Revolving Advance,

                             (iv)       in the case of each Eurodollar
                    Revolving Advance, the Interest Period applicable thereto.

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.

         3.4.       Competitive Bid Loans.

                    (a)      Competitive Bid Quote Request.  When the Company
         wishes to request offers to make Competitive Bid Loans under this
         Agreement, it shall transmit to the Administrative Agent by telex or
         telecopy a Competitive Bid Quote Request substantially in the form
         of Exhibit E hereto so as to be received no later than (i) 10:00 a.m.
         (Chicago time) at least four Business Days prior to the Borrowing Date
         proposed therein, in the case of a Eurodollar Auction or (ii) 9:00
         a.m.  (Chicago time) at least one Business Day prior to the Borrowing
         Date proposed therein, in the case of a Floating Rate Auction
         specifying:

                             (i)        the proposed Borrowing Date, which
                    shall be a Business Day, for the proposed Competitive Bid
                    Advance;

                             (ii)       the aggregate principal amount of such
                    Competitive Bid Advance;

                             (iii)      whether the Competitive Bid Quotes
                    requested are to set forth a Eurodollar Bid Rate or a
                    Floating Bid Rate, or both;

                             (iv)       in the case of each Floating Rate
                    Auction, the maturity date (relative to each Competitive
                    Bid Loan, its "Stated Maturity Date") for the proposed
                    Competitive Bid Advance (which Stated Maturity Date may not
                    be earlier than the date occurring





                                      26
   33
                    seven (7) days after the proposed Borrowing Date of such
                    Competitive Bid Advance or later than the earlier of (x)
                    the date occurring 185 days after the proposed Borrowing
                    Date of such Competitive Bid Advance and (y) the
                    Termination Date); and

                             (v)        in the case of each Eurodollar Bid Rate
                    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
                    thereof.

                    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
         constitute an invitation by the Company to each Lender to submit
         Competitive Bid Quotes offering to make the Competitive Bid Loans to
         which such Competitive Bid Quote Request relates in accordance with
         this Section 3.4; provided that the Administrative Agent shall not be
         required to send an Invitation for Competitive Bid Quotes to any
         Lender that has failed to submit a Competitive Bid Quote after each of
         the last three Invitations for Competitive Bid Quotes sent to such
         Lender unless the Company or such Lender has given notice to the
         Administrative Agent specifically referring to such Invitation for
         Competitive Bid Quotes and requesting that this proviso not apply to
         such Invitation for Competitive Bid Quotes, in which case this proviso
         automatically shall not apply to such Invitation for Competitive Bid
         Quotes.

                    (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





                                      27
   34
                             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 $5,000,000 and an
                    integral multiple of $1,000,000, 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;

                             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





                                      28
   35
         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;

                             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 Advance
shall be in the minimum amount of $5,000,000 (and in multiples of $1,000,000 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 $5,000,000 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.

         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





                                      30
   37
                    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 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, 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.

              MANDATORY PAYMENTS; REDUCTIONS OF COMMITMENTS; ETC.

         4.1.       [Intentionally Omitted.]





                                      31
   38
         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
         Engineering Banks and the Lenders of such proposed Sale, which notice
         shall describe such Property and, if known, the proposed terms of
         Sale.  In connection therewith the Company shall deliver to the
         Administrative Agent, the Engineering Banks and the Lenders such
         reports and information concerning such Property (which may include in
         the Engineering Banks' sole discretion an Approved Engineers' Report
         or a Company's Engineers' Report as of such date) and such Sale as
         each of the Engineering Banks shall deem appropriate in its sole
         discretion.  Promptly following receipt of such report and
         information, the Engineering Banks shall make a recommendation (and
         the Administrative Agent shall notify the Lenders in writing of such
         recommendation) of (A) if the Non-conforming Borrowing Base is $0.00,
         whether they approve of such Sale and, if so approved, 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 Aggregate Available Commitment pursuant to Section
         2.3(f)), and (B) if the Non-conforming Borrowing Base is not $0.00,
         whether to approve such sale, which recommendations shall be made by
         the Engineering Banks in the exercise of their sole
         discretion; provided, however, that in the event the Company or any
         Subsidiary proposes to consummate a Sale with respect to a Property
         not included within the Borrowing Base when the Non-conforming
         Borrowing Base is $0.00, no mandatory prepayment shall be required;
         and provided further, that in





                                      32
   39
         no event shall the Aggregate Available Commitment 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; and provided further,
         that until the Non-conforming Borrowing Base is $0.00, the Aggregate
         Available Commitment automatically shall be reduced upon consummation
         of any such approved Sale by an amount equal to the proceeds of such
         Sale net of costs, charges and taxes incidental to such Sale.  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 and of such Sale 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, and, if applicable, such amount of prepayment and such
         reduction in the Aggregate Available Commitment. 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) or, in the amount that the outstanding principal amount
         of the Loans exceeds the Aggregate Available Commitment as so
         automatically reduced, as the case may be.

                    (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 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





                                      33
   40
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 and the Non-conforming
Borrowing Base.  The Company may permanently reduce the Aggregate Commitment or
the Non-conforming Borrowing Base 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 and further provided
that any reduction of the Aggregate Commitment shall first reduce the portion
of the Aggregate Commitment attributable to the Non-conforming Borrowing Base
until the Non-conforming Borrowing Base is reduced to $0.00.  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





                                      35
   42
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).

         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 or any Guarantor 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 any Guarantor 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





                                      36
   43
         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 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 any Guarantor 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





                                      37
   44
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 Arrangers 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 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, and the Company has the corporate power and authority
and legal right to execute and deliver the Purchase and Sale Agreement and to
perform its obligations thereunder.  The execution and delivery by the Company
and each Subsidiary of the Loan Documents to which it is a party and the
execution and delivery by the Company of the Purchase and Sale Agreement and
the performance in each case of the Company's and such Subsidiary's obligations
thereunder have been duly authorized by proper corporate or partnership
proceedings, and the Loan Documents and the Purchase and Sale Agreement have
been duly executed and delivered and constitute legal, valid and binding
obligations of the Company and each Subsidiary party thereto, in each case
enforceable against the Company and such 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 and, in the
case of the Company, the Purchase and Sale Agreement, 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,





                                      41
   48
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 or the Purchase and Sale
Agreement.

         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, Apache Energy Resources, 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 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, 1989.  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 $10,000,000.  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.

business, the Company conducts an ongoing review of the effect of Environmental
Laws on the business, operations and Properties of the Company and its
Subsidiaries, in the course of which it identifies and evaluates associated

         Subsidiary consented to by the Required Lenders in the exercise of

provided, that if the Company shall request that any Indebtedness be permitted
as Subordinated Indebtedness pursuant to clause (c), as Limited Recourse
Indebtedness pursuant to clause (d), or as Indebtedness pursuant to clause (e),
the Administrative Agent or any Arranger shall notify the Company that it or

event the Company shall supply such information and reports provided pursuant
to such Section 2.3(b) and the Engineering Banks and the Required Lenders shall
make a determination of the Borrowing Base in accordance with the provisions of
Section 2.3(a), giving effect to such requested Indebtedness.  For purposes
hereof, "Limited Recourse Indebtedness" shall mean Indebtedness of a Person for

other than recourse limited to the cash flow from the assets constituting
collateral therefor and recourse to the extent necessary to enable amounts to
be claimed in respect of such Indebtedness upon an enforcement of any Lien on

assets (other than the assets the subject of such Lien) and (c) except as

Subsidiary; provided, however that the foregoing shall not prohibit mergers or
consolidations in any calendar year not in excess of five percent (5%) of the
consolidated total assets of the Company and its Consolidated Subsidiaries
immediately prior to the





                                      50
   57
initial such merger or consolidation during such calendar year if (i) the
Company or such Subsidiary, as the case may be, is the surviving entity of such
merger (and if a merger between the Company and any Subsidiary, the Company is
the surviving entity) and (ii) after giving effect to such merger or
consolidation, no Default or Unmatured Default shall occur and be continuing;
provided, further that the foregoing shall not prohibit the DEKALB Merger.

         11.3.      Sale of Assets.  The Company will not, nor will it permit

                    market value not in excess of $10,000,000 for all such
                    Sales permitted pursuant to this clause (ii) during any
                    consecutive six-month period.

                    clause (ii) or (iii) if the Required Lenders give prior
                    written consent to such Sale in the exercise of their sole
                    discretion; provided, that the consent of the Required
                    Lenders shall not be required for the Sale of the
                    Properties described in Schedule 11.3 hereof for at least

                    prior to the Effective Date delivered pursuant to Section
                    7.1 (xiv); provided, further, however, that concurrently
                    with any such Sale (A) if the Non-conforming Borrowing Base

                    Hydrocarbon inventory and severed oil and gas in the
                    ordinary course of business and other than assets
                    constituting Properties) if the Required Lenders give prior
                    written consent to such Sale in the exercise of their sole
                    discretion.

Anything herein contained to the contrary notwithstanding, the Company will
not, nor will it permit any Subsidiary to, consummate any Sale otherwise

commitments or obligations) has become obligated to perform, (e) Contingent

             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 each Guarantor 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
Guaranties or by law.  If any other Default occurs, (a) the Required Lenders
may terminate or





                                      58
   65
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 each Guarantor 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 elucidating 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.

                    (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 1994 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





                                      59
   66

warranties of the Company, MW Petroleum and any other Subsidiary contained in
the July 1991 Agreement, the April 1992 Agreement, the April 1994 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 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.
         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 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, Apache
                    Energy Resources or Apache Energy Limited 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 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
Agent with





                                      61
   68
sufficient counterparts so that the Administrative Agent may furnish one to
each of the Lenders and each of the Agents.

         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

                                   ARTICLE XV

                           THE ADMINISTRATIVE AGENT,
                    THE ARRANGERS AND THE ENGINEERING BANKS

         15.1.      Appointment of Agents.  The First National Bank of Chicago
is hereby appointed Administrative Agent and Arranger hereunder and under each
other Loan Document, and Chemical is hereby appointed Co-Agent and Arranger
hereunder and under each other Loan Document, and each of First Chicago and
Chemical is appointed as an Engineering Bank hereunder and each of the Lenders
irrevocably authorizes each such Agent to act in such capacities.  Each Agent
agrees to act as such upon the express conditions contained in this Article XV.
No Agent shall have a fiduciary relationship in respect of any Lender by reason
of this Agreement or any of the other Loan Documents.

         15.2.      Powers.  Each Agent shall have and may exercise such powers
under this Agreement and the other Loan Documents as are specifically delegated
to it by the terms of each thereof, together with such powers as are reasonably
incidental thereto.  None of the Agents shall have implied duties to the
Lenders, or any obligation to the Lenders to take any action thereunder except
any action by an Agent specifically provided by the Loan Documents to be taken
by such Agent.

         15.3.      General Immunity.  No Agent nor any of its respective
directors, officers, agents or employees shall be liable to any Lender or any
of the other Agents for any action taken or omitted to be taken by it or them
hereunder or under any other Loan Document or in connection herewith or
therewith except for its or their own gross negligence or wilful misconduct as
established by final order of a court of competent jurisdiction.

         15.4.      No Responsibility for Loans, Recitals, etc.  No Agent nor
any of its respective directors, officers, agents or employees shall be
responsible for or have any duty to ascertain, inquire into, or verify (i) any
statement, 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, 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

   70
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, each Arranger and
each Engineering Bank ratably in proportion to such Lender's Aggregate
Commitments, (i) for any amounts (other than principal or interest) not
reimbursed by the Company or any 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 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 15.2 and this Section 15.9, 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





                                      64
   71
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 with respect to 1994 Revolving
Loans which are outstanding on the Effective Date pursuant to Section 7.1(d)),
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 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





                                      65
   72
         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 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, 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 not
         an Affiliate of such assigning Lender, such assignment shall require
         the consent of the Company, which consent of the Company shall not be
         unreasonably withheld or delayed.  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





                                      66
   73
         required by Section 17.3.(a), and (ii) payment of a $3,000 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
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, each Agent, and each
Lender may change the address for service of notice upon it by a notice in
writing to the other parties hereto.

         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.
