          (d)  the aggregate outstanding principal amount of all Loans of such
     Lender, together with its Percentage of all Letter of Credit Outstandings,
     would exceed such Lender's Percentage of the Commitment Amount, or

          (e)  a Borrowing Base Deficiency would exist, or

          (f)  a Collateral Value Deficiency would exist, or

          (g)  an Event of Default has occurred and is continuing.

     SECTION 2.1.6.  ISSUER NOT REQUIRED TO ISSUE LETTERS OF CREDIT UNDER
CERTAIN CIRCUMSTANCES.  The Issuer shall not be required to issue any Letter of
Credit if, after giving effect thereto

                                      -36-

 
          (a) the aggregate outstanding principal amount of all Tranche A Loans
     would exceed the Tranche A Commitment Amount,

          (b) a Borrowing Base Deficiency would exist,

          (c) a Collateral Value Deficiency would exist,

          (d) all Letter of Credit Outstandings would exceed $1,000,000, or

subject to reduction from time to time pursuant to this Section 2.2.

     SECTION 2.2.1. OPTIONAL. The Borrowers may, from time to time on any
Business Day, voluntarily reduce the Commitments in the following order: first,
the Tranche B Commitment Amount and, when the Tranche B Commitment has been
reduced to zero, then the Tranche C Commitment Amount and, when the Tranche C
Commitment has been reduced to zero, then the Tranche A Commitment Amount;
provided, however, that all such reductions shall require at least three (3)
Business Days' prior notice to the Agent and be permanent, and any partial
reduction of the Commitment Amount shall be in a minimum amount of $250,000 and
in an integral multiple of $50,000.

     SECTION 2.2.2. MANDATORY.

          (a) On the Tranche A Availability Termination Date, the unused portion
     of the Tranche A Commitment Amount shall, without any further action,
     automatically and permanently be canceled.

     of the Tranche B Commitment Amount shall, without any further action,
     automatically and permanently be canceled.

          (c) On the Tranche C Availability Termination Date, the unused portion
     of the Tranche C Commitment Amount shall, without any further action,
     automatically and permanently be canceled.

          (d) On any Commitment Termination Date, the Commitment Amount of each

     SECTION 2.3. BORROWING PROCEDURE.

                                      -37-

 
          (a) By delivering a Borrowing Request to the Agent on or before 10:00
     a.m. (Chicago time) on a Business Day, the Borrowers may from time to time
     irrevocably request, on not less than three (3) nor more than five (5)
     Business Days' notice, or, in the case of a Base Rate Borrowing, one (1)
     Business Day's notice, that a Borrowing be made in a minimum amount of
     $250,000 and an integral multiple of $50,000, or in the unused amount of
     the applicable Commitment.  On the terms and subject to the conditions of
     this Agreement, each Borrowing shall be made on the Business Day specified
     in such Borrowing Request.  The Lenders shall make such funds available to
     the Borrowers by wire transfer to the accounts the Borrowers shall have
     specified in their Borrowing Request.  On or before 11:00 a.m. (Chicago
     time) on such Business Day each Lender shall deposit with the Agent same
     day funds in an amount equal to such Lender's Percentage of the requested
     Borrowing.  Such deposit will be made to an account which the Agent shall
     specify from time to time by notice to the Lenders.  To the extent funds
     are received from the Lenders, the Agent shall make such funds available to
     the Borrowers by wire transfer to the accounts the Borrowers shall have
     specified in their Borrowing Request.  No Lender's obligation to make any
     Loan shall be affected by any other Lender's failure to make any Loan.

          (b) Each Lender may, if it so elects, fulfill its obligation to make,
     continue or convert LIBO Rate Loans hereunder by causing one of its foreign
     branches or  Affiliates (or an international banking facility created by
     such Lender) to make or maintain such LIBO Rate Loan; provided, however,
     that such LIBO Rate Loan shall nonetheless be deemed to have been made and
     to be held by such Lender, and the obligation of the Borrowers to repay
     such LIBO Rate Loan shall nevertheless be to such Lender for the account of
     such foreign branch, Affiliate or international banking facility.  In
     addition, the Borrowers hereby consent and agree that, for purposes of any
     determination to be made for purposes of Section 5.1, 5.2, 5.3 or 5.4, it
     shall be conclusively assumed that each Lender elected to fund all LIBO
     Rate Loans by purchasing Dollar deposits in its LIBO Office's interbank
     eurodollar market.

     SECTION 2.4. CONTINUATION AND CONVERSION ELECTIONS. By delivering a
Continuation/Conversion Notice to the Agent on or before 10:00 a.m. (Chicago
time) on a Business Day, the Borrowers may from time to time irrevocably elect,
on not less than three (3) nor more than five (5) Business Days' notice that
all, or any portion in an aggregate minimum amount of $250,000 and an integral
multiple of $50,000, of any Loans, in the case of Base Rate Loans, be converted
into LIBO Rate Loans or, in the case of LIBO Rate Loans, be converted into a
Base Rate Loan or continued as a LIBO Rate Loan (in the absence of delivery of a
Continuation/Conversion Notice with respect to any LIBO Rate Loan at least three
(3) Business Days before the last day of the then current Interest Period with
respect thereto, such LIBO Rate Loan shall, on such last day, automatically
convert to a Base Rate Loan); provided, however, that 

                                      -38-

 
no portion of the outstanding principal amount of any LIBO Rate Loan may be
continued as, and no portion of any Base Rate Loan may be converted into, LIBO
Rate Loans when any Default has occurred and is continuing.

     SECTION 2.5. LOAN ACCOUNTS AND NOTES.

          (a) The Loans made by each Lender shall be evidenced by one or more
     loan accounts or records maintained by such Lender in the ordinary course
     of business.  The loan accounts or records maintained by such Lender shall
     be conclusive absent manifest error of the amount of the Loans made by such
     Lender to the Borrowers and the interest and payments thereon.  Any failure
     so to record or any error in doing so shall not, however, limit or
     otherwise affect the obligations of the Borrowers hereunder to pay any
     amount owing with respect to the Loans.

          (b) Each Lender's Loans shall also be evidenced by a Note payable to
     the order of such Lender in a maximum principal amount equal to the
     Lender's Percentage of the original, aggregate Commitment Amount.  The
     Borrowers hereby irrevocably authorize each Lender to make (or cause to be
     made) appropriate notations on the grid attached to the Note (or on any
     continuation of such grid) or in other books and records maintained by such
     Lender, which notations, if made, shall evidence, inter alia, the date of,
     the outstanding principal of, and the interest rate applicable to the Loans
     evidenced thereby (the Borrowers may from time to time reasonably request a
     copy of such grid). Such notations shall be conclusive and binding on the
     Borrowers absent manifest error; provided, however, that the failure of any
     Lender to make any such notations shall not limit or otherwise affect any
     Obligations of the Borrowers or any other Obligor.

          (c) The Borrowers acknowledge that the Notes delivered to the Lenders
     as of the Effective Date amend, restate and renew the promissory notes
     given by the Original Borrowers under the Existing Agreement, which
     amended, restated, consolidated and renewed certain promissory notes and
     other evidence of indebtedness then outstanding.

     SECTION 2.6. BORROWING BASE REDETERMINATION AND COLLATERAL VALUE
REDETERMINATION.

          (a) Within thirty (30) days after receipt of the Engineering Report
     required to be delivered semi-annually, commencing with the interim
     Engineering Report described in Section 2.6(c), (and thereafter in
     connection with the regular, semi-annual Engineering Report), the Agent
     shall notify the Borrowers in writing of the Borrowing Base determined by
     the Agent on the basis of such Engineering Report.  After July 1, 1999, the
     Borrowers or the 

                                      -39-

 
     Agent may request, and Agent will consider, one (1) additional
     determination of the Borrowing Base at any time during each calendar year,
     including 1999. Each such determination is herein called a "Borrowing Base
     Redetermination". Contemporaneously with each Borrowing Base
     Redetermination that shall occur at any time that any Tranche B Loan is
     outstanding, the Agent shall notify the Borrowers in writing of the
     Collateral Value determined by the Agent on the basis of such Engineering
     Report. Each such determination is herein called a "Collateral Value
     Redetermination". Each Borrowing Base Redetermination (and, as applicable,
     Collateral Value Redetermination) shall be effective as of July 31st (with
     respect to Engineering Reports effective May 1st), January 31st (with
     respect to Engineering Reports effective November 1st) or upon notice from
     the Agent (with respect to any requested Borrowing Base redetermination)
     when the Borrowers are notified of the amount of the redetermined Borrowing
     Base (and, as applicable, the amount of the redetermined Collateral Value)
     by the Agent.

          (b) The Borrowing Base and Collateral Value are also subject to
     adjustment as provided for in Section 3.1.2.

          (c) In addition to the semi-annual Engineering Reports referred to
     above (and in lieu of a November 1 Report for 1998), an interim Reserve and
     Economic Report shall be delivered to Agent by March 31, 1999, and shall
     consist of independent engineering evaluations on all of Borrower's U.S.
     Mortgaged Properties, and the East Irish Sea Assets, if significant changes
     have occurred with respect to the East Irish Sea Assets since the Effective
     Date. Such evaluation shall be prepared by independent consultants which
     are acceptable to the Agent and shall form the basis for the initial
     Borrowing Base Redetermination.  The Agent shall give notice to the
     Borrowers not later than June 1, 1999, of the Borrowing Base and Collateral
     Value determined by the Agent, and such Borrowing Base Redetermination and
     Collateral Value Redetermination shall be effective as of July 1, 1999.

     SECTION 2.7. PURPOSES. The Borrowers shall apply the proceeds of each Loan
only in the following manner:

          (a) in the case of Tranche A Loans, to refinance existing
     indebtedness, for working capital purposes of the Borrowers and to finance
     Approved Development Activities; and

          (b) in the case of Tranche B Loans, as follows:

               1. A portion of the purchase price of the East Irish Sea Assets,
                  in an amount not to exceed $8.0 million;

                                      -40-

 
               2. Approved Development Activities in respect of the Mortgaged
                  Properties (other than the East Irish Sea Assets), in an
                  amount not to exceed $2.0 million;

               3. Fees and expenses incurred in connection with the acquisition
                  and financing of the East Irish Sea Assets, in an amount not
                  to exceed in the aggregate $4 million (provided the Borrowers
                  have furnished to the Agent, along with the Borrowing Request
                  applicable thereto, a detailed schedule, satisfactory to the
                  Agent, of such fees and expenses);

               4. Approved Development Activities in respect of the East Irish
                  Sea Assets; and

          (c) in the case of Tranche C Loans, for general corporate and working
     capital purposes.

                                  ARTICLE III

                  REPAYMENTS, PREPAYMENTS, INTEREST AND FEES

     SECTION 3.1. REPAYMENTS AND PREPAYMENTS AND CERTAIN BORROWING BASE MATTERS.
The Borrowers shall repay the unpaid principal amount of the Loans as set forth
in this Section 3.1.

     SECTION 3.1.1. REPAYMENTS AND PREPAYMENTS. The Borrower shall repay in full
the unpaid principal amount of each Tranche A Loan, and each Tranche A Loan
shall mature and be due and payable, on the Tranche A Availability Termination
Date; provided, however, that if no Event of Default has occurred and is
continuing, the unpaid principal amount of the Tranche A Loans shall, on the
Tranche A Availability Termination Date and in response to a Borrowing Request
delivered to the Lender, not be due and payable but shall convert to term Loans.
The Borrowers shall repay in full the unpaid principal amount of each Loan upon
the applicable Stated Maturity Date. Prior thereto, the Borrowers

          (a) may, from time to time on any Business Day, make a voluntary
     prepayment, in whole or in part, of the outstanding principal amount of any
     Loans; provided, however, that

               (i) any such prepayment shall be made pro rata among Loans of the
          same type and tranche;

                                      -41-

 
               (ii)  no such prepayment of any LIBO Rate Loan may be made on any
          day other than the last day of the Interest Period for such Loan;

               (iii) all such voluntary prepayments shall require at least three
          (3) but no more than five (5) Business Days' prior written notice to
          the Agent (which notice is irrevocable) stating the date and amount of
          such prepayment and the type of Loan to be prepaid; and

               (iv)  all such voluntary partial prepayments shall be in an
          aggregate minimum amount of $100,000 and an integral multiple of
          $50,000;

          (b) shall, on each date when any reduction in any Commitment Amount
     shall become effective, including pursuant to Section 2.2, make a mandatory
     prepayment (which shall be applied (or held for application, as the case
     may be) by each Lender to the payment of the aggregate unpaid principal
     amount of those Loans then outstanding and then to the payment of the then
     Letter of Credit Outstandings) equal to the excess, if any, of the
     aggregate outstanding principal amount of all Loans and Letter of Credit
     Outstandings over such Commitment Amount as so reduced;

          (c) shall make prepayments as specified in Section 3.1.2;

          (d) shall, on each Quarterly Payment Date, make a payment in an amount
     not less than the interest payment required pursuant to Section 3.2.3;

          (e) shall, on each Quarterly Payment Date beginning January 31, 2001,
     make a payment in an amount equal to that necessary to amortize the
     principal of all Tranche C Loans equally over the remaining Quarterly
     Payment Dates and the applicable Stated Maturity Date;

          (f) shall, if Tranche A Loans have been converted to a term Loan
     pursuant to the terms and conditions hereof, on each Quarterly Payment Date
     after the Tranche A Availability Termination Date, make a payment in an
     amount equal to that necessary to amortize the principal of all Tranche A
     Loans equally over the remaining Quarterly Payment Dates and the applicable
     Stated Maturity Date;

          (g) shall, on the Tranche B Availability Termination Date, pay the
     entire outstanding principal amount of all Tranche B Loans;

          (h) shall, immediately upon any acceleration of the Loans pursuant to
     Section 9.2 or Section 9.3, repay all Loans, unless, pursuant to Section
     9.3, only a portion of all Loans is so accelerated.

                                      -42-

 
Each payment or prepayment of any Loans made pursuant to this Section shall be
without premium or penalty, except as may be required by Section 5.4, and shall
be applicable, to the extent of such prepayment, in the inverse order of
maturity.  No voluntary prepayment of principal of any Loans or any prepayment
pursuant to the preceding clause (c) shall cause a reduction in any Commitment
Amount.

     SECTION 3.1.2. BORROWING BASE DEFICIENCIES, COLLATERAL VALUE DEFICIENCIES
AND ASSET SALES.

          (a) Upon the occurrence of a Borrowing Base Deficiency and/or a
     Collateral Value Deficiency, the Agent may notify the Borrowers of such
     Borrowing Base Deficiency and/or such Collateral Value Deficiency, as
     applicable.  Within ten (10) Business Days from and after the Borrowing
     Base Deficiency Notification Date and/or such Collateral Value Deficiency
     Notification Date, as applicable, the Borrowers shall notify the Agent and
     the Lenders that they shall take one of the following actions:

               (i)  execute and deliver to the Agent supplemental or additional
          Security Documents, in form and substance reasonably satisfactory to
          the Agent and its counsel, securing payment of the Notes and the other
          Obligations and covering additional Oil and Gas Properties directly
          owned by the Borrowers or one or more of the Borrowers' Subsidiaries
          which are not then covered by any Loan Document and which are of a
          type and nature satisfactory to the Agent, and having a value, in
          addition to other Oil and Gas Properties already subject to a Mortgage
          (determined by the Lender using customary standards for oil and gas
          lending), sufficient to eliminate the Borrowing Base Deficiency and/or
          the Collateral Value Deficiency, as applicable, all as more
          particularly described in Section 8.1.7(a) and (b); or

               (ii) make a payment with respect to the Obligations (which shall
          be applied (or held for application, as the case may be) by the
          Lenders to the payment of the aggregate unpaid principal amount of
          those Loans then outstanding and then to the payment of the then
          Letter of Credit Outstandings) in an aggregate principal amount
          sufficient to eliminate such Borrowing Base Deficiency and/or
          Collateral Value Deficiency, as applicable, within sixty (60) days
          after the Borrowing Base Deficiency Notification Date or Collateral
          Value Deficiency Notification Date, as applicable.

     If the Borrowers shall elect to execute and deliver (or cause one or more
     of the Borrowers' Subsidiaries to execute and deliver) supplemental or
     additional Security Documents to the Agent pursuant to clause (i), they
     shall provide the Agent with descriptions of the additional assets to be
     collaterally assigned 

                                      -43-

 
     (together with current valuations, Engineering Reports, Security Documents
     described in clause (i) and title evidence applicable thereto, each of
     which shall be in form and substance reasonably satisfactory to the Agent)
     within sixty (60) days after the Borrowing Base Deficiency Notification
     Date or Collateral Value Deficiency Notification Date, as applicable. Such
     supplemental or additional Security Documents shall be subject to the terms
     of Section 8.1.7. If the Borrowers fail to take any of the actions
     described in clauses (i) or (ii) above within such ten (10) Business Day
     period, then without any necessity for notice to the Borrowers or any other
     person, the Borrowers shall become obligated immediately to pay Obligations
     in an aggregate principal amount equal to the applicable Borrowing Base
     Deficiency and/or Collateral Value Deficiency.

          (b) If the Borrowers or any of their Subsidiaries sells, transfers or
     otherwise disposes of Oil and Gas Properties included in the most recent
     determination of the Borrowing Base and the Collateral Value and that have
     a fair market value in the aggregate for the Borrowers and such
     Subsidiaries in excess of $250,000 during the period from the effective
     date of the most recent Borrowing Base Redetermination until the effective
     date of the next Borrowing Base Redetermination, the Borrowing Base and the
     Collateral Value shall be immediately reduced, until the effective date of
     the next Borrowing Base Redetermination and Collateral Value
     Redetermination, by an amount as reasonably determined by the Agent, or if
     the value of the applicable Oil and Gas Properties cannot be readily
     determined by the Agent, by the net sales proceeds realized from the sale,
     transfer or other disposition of such assets.

     If such reduction shall result in a Borrowing Base Deficiency and/or
     Collateral Value Deficiency, then in lieu of the provisions of clause (a)
     of Section 3.1.2, the Borrowers shall immediately make a payment with
     respect to the Obligations in an amount equal to the greater of such
     Borrowing Base Deficiency or such Collateral Value Deficiency.  In addition
     to and cumulative of the foregoing, if a Borrowing Base Deficiency and/or
     Collateral Value Deficiency exists prior to such sale, transfer or other
     disposition of assets, then in lieu of the provisions of clause (a) of
     Section 3.1.2, the Borrower shall, with the written consent of the Agent,
     immediately make a payment with respect to the Obligations (which shall be
     applied (or held for application, as the case may be) by the Lenders first
     to the payment of the aggregate unpaid principal amount of those Loans then
     outstanding, and then to the payment of the then Letter of Credit
     Outstandings) in an aggregate principal amount equal to the lesser of (i)
     the greater of the amount of the Collateral Value Deficiency or the amount
     of the Borrowing Base Deficiency (after giving effect to the applicable
     sale, transfer or other disposition) or (ii) 100% of the net sales proceeds
     realized from the applicable sale, transfer or other disposition.

                                      -44-

 
          (c) In addition, if the Borrowers or any of their Subsidiaries raises
     capital through the issuance of any type of equity or issues any
     subordinated debt or senior unsecured debt, the proceeds of such issuance
     will first be applied to cure any Borrowing Base Deficiency and/or
     Collateral Value Deficiency, then as a prepayment of Tranche B Loans and a
     permanent reduction of the Tranche B Commitment, and finally as a
     prepayment of Tranche C Loans and a permanent reduction of the Tranche C
     Commitment.

     SECTION 3.2. INTEREST PROVISIONS. Interest on the outstanding principal
amount of Loans shall accrue and be payable in accordance with this Section 3.2.

     SECTION 3.2.1. RATE. Pursuant to an appropriately delivered Borrowing
Request or Continuation/Conversion Notice, the Borrowers may elect that Loans
accrue interest at a rate per annum:

          (a) on that portion maintained from time to time as a Base Rate Loan,
     equal to the Alternate Base Rate plus the Applicable Margin from time to
     time in effect; and

          (b) on that portion maintained as a LIBO Rate Loan, during each
     Interest Period applicable thereto, equal to the sum of the LIBO Rate
     (Reserve Adjusted) for such Interest Period plus the Applicable Margin.

All LIBO Rate Loans shall bear interest from and including the first day of the
applicable Interest Period to (but not including) the last day of such Interest
Period at the interest rate determined as applicable to such LIBO Rate Loan.

     SECTION 3.2.2. POST-MATURITY RATES. After (w) the date any principal amount
of any Loan shall have become due and payable (whether on the Stated Maturity
Date, upon acceleration or otherwise), (x) the date any other monetary
Obligation of the Borrowers shall have become due and payable, (y) the date any
other Event of Default shall have occurred (and so long as such Event of Default
shall be continuing), and (z) the date that is sixty (60) days after a Borrowing
Base Deficiency Notification Date or a Collateral Value Deficiency Notification
Date, if the applicable Borrowing Base Deficiency or Collateral Value Deficiency
has not been cured, the Borrowers shall pay, but only to the extent permitted by
Applicable Law, interest (after as well as before judgment) on all Obligations
at a rate per annum equal to

          (a) with respect to LIBO Rate Loans for the period from the date such
     Loan becomes due and payable to the end of the then current Interest
     Period, the higher of (i) the sum of the LIBO Rate (Reserve Adjusted) for
     such Interest Period plus the Applicable Margin plus a margin of 3%, or (ii
     the sum of the Alternate Base Rate plus the Applicable Margin plus a margin
     of 3%; or

                                      -45-

 
          (b) in all other cases, the sum of the Alternate Base Rate plus the
     Applicable Margin plus a margin of 3%.

     SECTION 3.2.3. PAYMENT DATES. Interest accrued on each Loan shall be
payable, without duplication:

          (a)  on the Stated Maturity Date;

          (b) on the date of any optional or required payment or prepayment, in
     whole or in part, of principal outstanding on such Loan and on that portion
     of such Loan so paid or prepaid;

          (c) with respect to Base Rate Loans, on each Quarterly Payment Date
     occurring after the Effective Date;

          (d) with respect to LIBO Rate Loans, on the last day of each
     applicable Interest Period (and, if such Interest Period shall exceed three
     months, on the 90th day of such Interest Period); and

          (e) on that portion of any Loans which is accelerated pursuant to
     Section 9.2 or Section 9.3, immediately upon such acceleration.

Interest accrued on Loans or other monetary Obligations arising under this
Agreement or any other Loan Document after the date such amount shall have
become due and payable (whether on the Stated Maturity Date, upon acceleration
or otherwise) shall be payable upon demand.

     SECTION 3.2.4. MAXIMUM INTEREST. It is the intention of the parties hereto
to conform strictly to applicable usury laws and, anything herein to the
contrary notwithstanding, the Obligations of the Borrowers to the Lenders under
this Agreement shall be subject to the limitation that payments of interest
shall not be required to the extent that receipt thereof would be contrary to
provisions of Applicable Law applicable to the Lenders limiting rates of
interest which may be charged or collected by the Lenders. Accordingly, if the
transactions contemplated hereby would be usurious under Applicable Law with
respect to the Lenders then, in that event, notwithstanding anything to the
contrary in this Agreement, it is agreed as follows:

          (a) the provisions of this Section 3.2.4 shall govern and control;

          (b) the aggregate of all consideration which constitutes interest
     under Applicable Law that is contracted for, charged or received under this
     Agreement, or under any of the other aforesaid agreements or otherwise in
     connection with this Agreement by the Lenders shall under no circumstances

                                      -46-

 
     exceed the maximum amount of interest allowed by Applicable Law (such
     maximum lawful interest rate, if any, with respect to the Lenders herein
     called the "Highest Lawful Rate"), and any excess shall be credited to the
     Borrowers by the Lenders (or, if such consideration shall have been paid in
     full, such excess refunded to the Borrowers);

          (c) all sums paid, or agreed to be paid, to the Lenders for the use,
     forbearance and detention of the indebtedness of the Borrowers to the
     Lenders hereunder shall, to the extent permitted by Applicable Law, be
     amortized, prorated, allocated and spread throughout the full term of such
     indebtedness until payment in full so that the actual rate of interest is
     uniform throughout the full term thereof; and

          (d) if at any time the interest provided pursuant to Sections 3.2.1
     and 3.2.2 together with any other fees payable pursuant to this Agreement
     and deemed interest under Applicable Law, exceeds that amount which would
     have accrued at the Highest Lawful Rate, the amount of interest and any
     such fees to accrue to the Lenders pursuant to this Agreement shall be
     limited, notwithstanding anything to the contrary in this Agreement, to
     that amount which would have accrued at the Highest Lawful Rate, but any
     subsequent reductions, as applicable, shall not reduce the interest to
     accrue to such Lender pursuant to this Agreement below the Highest Lawful
     Rate until the total amount of interest accrued pursuant to this Agreement
     and such fees deemed to be interest equals the amount of interest which
     would have accrued to such Lender if a varying rate per annum equal to the
     interest provided pursuant to Sections 3.2.1 and 3.2.2 had at all times
     been in effect, plus the amount of fees which would have been received but
     for the effect of this Section 3.2.4.

     SECTION 3.3. FEES. The Borrowers agree to pay the fees set forth in this
Section 3.3 and in the Fee Letter. All such fees shall be non-refundable.

     SECTION 3.3.1. UNUSED FEE. The Borrowers shall pay to the Agent for the
account of the Lenders an unused fee, for the period from and including the
Effective Date to, but not including the earlier to occur of (x) the Tranche A
Availability Termination Date, and (y) the Commitment Termination Date, equal to
0.50 of 1% per annum of the average of the actual daily amount during the prior
Fiscal Quarter of (a) $55,000,000 minus (b) the sum of the aggregate outstanding
principal amount of all Loans and all Letter of Credit Outstandings, based on a
year comprised of three hundred sixty (360) days. Accrued unused fees shall be
payable in arrears on each Quarterly Payment Date and on the earlier of the
Commitment Termination Date or the Tranche A Availability Termination Date.

     SECTION 3.3.2. LETTER OF CREDIT STATED AMOUNT FEE. The Borrowers agree to
pay to the Agent, for the account of the Issuer, a fee for each Letter of Credit
for the 

                                      -47-

 
period from and including the date of the issuance of such Letter of
Credit to (but not including) the date upon which such Letter of Credit expires,
at a rate per annum equal to the Applicable Margin for Tranche A Loans
maintained as LIBO Rate Loans on the Stated Amount of such Letter of Credit,
based on a year comprised of three hundred and sixty (360) days. A prorated
portion of such fee shall be payable by the Borrowers in arrears on each
Quarterly Payment Date, and on the earlier of the Tranche A Availability
Termination Date and the Tranche A Commitment Termination Date for any period
then ending for which such fee shall not theretofore have been paid, commencing
on the first such date after the issuance of such Letter of Credit. After any
Borrowing Base Deficiency and/or Collateral Value Deficiency has or have existed
for sixty (60) consecutive days, the Stated Amount Fee on all Letters of Credit
shall increase by 3.00% until such Borrowing Base Deficiency and/or Collateral
Value Deficiency has or have been eliminated.

     SECTION 3.3.3. LETTER OF CREDIT ISSUANCE FEE. The Borrowers agree to pay to
the Agent, for the account of the Issuer, an issuance fee for each Letter of
Credit issued by the Issuer for the period from and including the date of
issuance of such Letter of Credit to (but not including) the date upon which
such Letter of Credit expires, of the greater of 0.25 of 1% of the Stated Amount
of such Letter of Credit or $300.00. Such fee shall be payable on the date of
issuance of such Letter of Credit.

     SECTION 3.3.4. LETTER OF CREDIT ADMINISTRATIVE FEES. The Borrowers agree to
pay to the Agent, for the account of the Issuer, all reasonable administrative
expenses of the Issuer in connection with the maintenance, modification (if any)
and administration of each Letter of Credit issued by the Issuer upon demand
from time to time pursuant to the Issuer's schedule of charges then in effect.

     SECTION 3.4. PROCEEDS ACCOUNT. The Security Documents contain an assignment
to the Agent by the Borrowers and/or their Subsidiaries, as applicable, of all
production of Hydrocarbons and all proceeds attributable thereto properly
allocable to the Mortgaged Properties. Notwithstanding such assignment of
production, the Borrowers may, until the Agent shall give notice to the
contrary, which notice shall not be unreasonably given, receive such proceeds.
Thereafter, all such proceeds from the sale of such production shall be paid
directly into an account of the Borrowers maintained with the Agent (the
"Proceeds Account"). The Borrowers hereby grant to the Agent, subject to the
prior assignment in favor of the Agent of such production and its proceeds, a
security interest in the Proceeds Account and all proceeds thereof.

     SECTION 3.5. ORRI AND WARRANTS ARE NOT COLLATERAL SECURITY.

          (a) In addition to interest paid on the Loans, Alliance Plc shall
     issue the Warrants and Difco shall grant the Overriding Royalty Interest to
     the 

                                      -48-

 
     Agent's designee ("Designee"), as additional consideration payable to
     the Agent to be retained in perpetuity and not as additional collateral
     security for the Obligations.

          (b) If all Tranche B Loans are paid in full and the Tranche B
     Commitment is terminated on or before March 26, 2000, then the Borrowers
     may purchase the Overriding Royalty Interest in consideration of the
     payment of a mutually satisfactory purchase price.  Such conveyance shall
     be without recourse, representation or warranty of any kind, except that
     the Designee shall warrant against liens created by, through or under the
     Designee.

          (c) The Overriding Royalty Interest described in the foregoing
     subsections (a) and (b) shall not affect in any way the overriding royalty
     interests previously acquired by the Designee pursuant to the Prior
     Agreement (which was subsequently exchanged for warrants and other
     obligations in respect of Alliance Plc).  Similarly, the Warrants to be
     issued pursuant to this Agreement shall not affect in any way the warrants
     issued to the Designee pursuant to the Prior Agreement.


                                  ARTICLE IV.

                               LETTERS OF CREDIT

     SECTION 4.1. ISSUANCE REQUESTS. By delivering to the Agent an Issuance
Request on or before 12:00 noon (Chicago time), the Borrowers may request, from
time to time prior to the earlier to occur of (x) the Tranche A Availability
Termination Date and (y) any Commitment Termination Date relating to all
Commitments or to the Tranche A Commitment, and on not less than three (3) nor
more than ten (10) Business Days' notice, that the Issuer issue an irrevocable
standby letter of credit in substantially the form of Exhibit K hereto, or in
such other form as may be mutually agreed by the Borrowers and the Issuer (each
a "Letter of Credit"), in support of financial obligations of the Borrowers
incurred in the Borrowers' ordinary course of business and which are described
in such Issuance Request. Upon receipt of an Issuance Request, the Agent shall
promptly notify the Lenders and the Issuer thereof. Each Letter of Credit shall
by its terms:

          (a) be issued in a Stated Amount which

               (i)  is at least $10,000;

               (ii) does not exceed (or would not exceed) the then Letter of
          Credit Availability;

                                      -49-

 
          (b) be stated to expire on a date (its "Stated Expiry Date") no later
     than the earlier of (i) one (1) year after its date of issuance and (ii the
     Commitment Termination Date; and

          (c) on or prior to its Stated Expiry Date

               (i)   terminate immediately upon notice to the Issuer from the
          beneficiary thereunder that all obligations covered thereby have been
          terminated, paid, or otherwise satisfied in full,

               (ii)  reduce in part immediately and to the extent the 
          beneficiary thereunder has notified the Issuer that the obligations
          covered thereby have been paid or otherwise satisfied in part, or

               (iii) terminate thirty (30) Business Days after notice to the
          beneficiary thereunder from the Agent that an Event of Default has
          occurred and is continuing.

So long as no Default has occurred and is continuing, by delivery to the Agent
and the Issuer of an Issuance Request at least three (3) but not more than ten
(10) Business Days prior to the Stated Expiry Date of any Letter of Credit, the
Borrowers may request the Issuer to extend the Stated Expiry Date of such Letter
of Credit for an additional period not to exceed the earlier of one (1) year
from its date of extension, the Availability Termination Date or the Commitment
Termination Date.

     SECTION 4.2. ISSUANCES AND EXTENSIONS. On the terms and subject to the
conditions of this Agreement (including Article VI), the Issuer shall issue 
Letters of Credit, and extend the Stated Expiry Dates of outstanding Letters of
Credit, in accordance with the Issuance Requests made therefor. The Issuer will
make available the original of each Letter of Credit which it issues in
accordance with the Issuance Request therefor to the beneficiary thereof (and
will promptly provide the Agent and each of the Lenders with a copy of such
Letter of Credit) and will notify the beneficiary under any Letter of Credit of
any extension of the Stated Expiry Date thereof.

     The Issuer is under no obligation to issue any Letter of Credit if:

          (i) any order, judgment or decree of any Governmental Agency or
     arbitrator shall by its terms purport to enjoin or restrain the Issuer from
     issuing such Letter of Credit, or any requirement of Applicable Law or any
     request or directive (whether or not having the force of law) from any
     Governmental Agency with jurisdiction over the Issuer shall prohibit, or
     request that the Issuer refrain from, the issuance of letters of credit
     generally or such Letter of Credit in particular or shall impose upon the
     Issuer or the Lenders with respect 

                                      -50-

 
     to such Letter of Credit any restriction, reserve or capital requirement
     (for which the Issuer is not otherwise compensated hereunder) not in effect
     on the Effective Date, or shall impose upon the Issuer any unreimbursed
     loss, cost or expense which was not applicable on the Effective Date and
     which the Issuer in good faith deems material to it;

          (ii)  one or more of the applicable conditions contained in Article VI
     is not then satisfied;

          (iii) the expiry date of any requested Letter of Credit is prior to
     the maturity date of any financial obligation to be supported by the
     requested Letter of Credit;

          (iv)  any requested Letter of Credit does not provide for drafts, or 
     is not otherwise in form and substance acceptable to the Issuer, or the
     issuance of a Letter of Credit shall violate any applicable policies of the
     Issuer;

          (v)   any standby Letter of Credit is for the purpose of supporting 
     the issuance of any letter of credit by any other Person; or

          (vi)  such Letter of Credit is in a face amount denominated in a
     currency other than Dollars.

The Uniform Customs and Practice for Documentary Credits as published by the
International Chamber of Commerce most recently at the time of issuance of any
Letter of Credit shall (unless otherwise expressly provided in the Letters of
Credit) apply to the Letters of Credit.

     SECTION 4.3. DISBURSEMENTS. The Issuer will notify the Borrowers promptly
of the presentment for payment of any Letter of Credit, together with notice of
the date (the "Disbursement Date") such payment shall be made. Subject to the
terms and provisions of such Letter of Credit, the Issuer shall make such
payment to the beneficiary (or its designee) of such Letter of Credit. In paying
any drawing under a Letter of Credit, the Issuer shall not have any
responsibility to obtain any document (other than any sight draft and
certificates expressly required by the Letter of Credit) or to ascertain or
inquire as to the validity or accuracy of any such document or the authority of
the Person executing or delivering any such document. Prior to 12:00 noon
(Chicago time) on the Disbursement Date, the Borrowers will reimburse the Issuer
for all amounts which it has disbursed under the Letter of Credit. To the extent
the Issuer is not reimbursed in full in accordance with the preceding sentence,
the Borrowers' Reimbursement Obligation shall accrue interest at a fluctuating
rate equal to the lesser of (i) the Highest Lawful Rate or (ii) the Alternate
Base Rate, plus the Applicable Margin plus a margin of 2% per annum, payable on
demand. In the event the Issuer is not reimbursed by the Borrowers on the
Disbursement Date, or if Issuer 

                                      -51-

 
must for any reason return or disgorge such reimbursement, BankAmerica shall, on
the terms and subject to the conditions of this Agreement, fund the
Reimbursement Obligation therefor by making, on the next Business Day, Tranche A
Loans which are Base Rate Loans as provided in Section 2.1.2 (the Borrowers
being deemed to have given a timely Borrowing Request therefor for such amount);
provided, however, for the purpose of determining the availability of the
Commitments to make Loans immediately prior to giving effect to the application
of the proceeds of such Loans, such Reimbursement Obligation shall be deemed not
to be outstanding at such time.

     SECTION 4.4. REIMBURSEMENT. The Borrowers' obligation (a "Reimbursement
Obligation") under Section 4.3 to reimburse the Issuer with respect to each
Disbursement (including interest thereon) shall be absolute and unconditional
under any and all circumstances and irrespective of any setoff, counterclaim, or
defense to payment which the Borrowers may have or have had against the Lenders,
the Issuer or any beneficiary of a Letter of Credit, including any defense based
upon the occurrence of any Default, any draft, demand or certificate or other
document presented under a Letter of Credit proving to be forged, fraudulent,
invalid or insufficient, the failure of any Disbursement to conform to the terms
of the applicable Letter of Credit (if, in the Issuer's good faith opinion, such
Disbursement is determined to be appropriate) or any non-application or
misapplication by the beneficiary of the proceeds of such Disbursement, or the
legality, validity, form, regularity, or enforceability of such Letter of
Credit; provided, however, that nothing herein shall adversely affect the right
of the Borrowers to commence any proceeding against the Issuer for any wrongful
Disbursement made by the Issuer under a Letter of Credit as a result of acts or
omissions constituting gross negligence or wilful misconduct on the part of the
Issuer.

     SECTION 4.5. DEEMED DISBURSEMENTS. Upon the occurrence and during the
continuation of any Event of Default or the occurrence of the Commitment
Termination Date, an amount equal to that portion of Letter of Credit
Outstandings attributable to outstanding and undrawn Letters of Credit shall, at
the election of the Issuer, acting on instructions from the Required Lenders,
and without demand upon or notice to the Borrowers, be deemed to have been paid
or disbursed by the Issuer under such Letters of Credit (notwithstanding that
such amount may not in fact have been so paid or disbursed), and, upon
notification by the Issuer to the Agent and to the Borrowers of its obligations
under this Section, the Borrowers shall be immediately obligated to reimburse
the Issuer the amount deemed to have been so paid or disbursed by the Issuer.
Any amounts so received by the Issuer from the Borrowers pursuant to this
Section shall be held as collateral security for the repayment of the Borrowers'
obligations in connection with the Letters of Credit issued by the Issuer. At
any time when such Letters of Credit shall terminate and all Obligations to the
Issuer are either terminated or paid or reimbursed to the Issuer in full, the
Obligations of the Borrowers under this Section shall be reduced accordingly
(subject, however, to reinstatement in the event any payment in respect of such

                                      -52-

 
Letters of Credit is recovered in any manner from the Issuer), and the Issuer
will return to the Borrowers the excess, if any, of

          (a) the aggregate amount deposited by the Borrowers with the Issuer
     and not theretofore applied by the Issuer to any Reimbursement Obligation

over

          (b) the aggregate amount of all Reimbursement Obligations to the
     Issuer pursuant to this Section, as so adjusted.

At such time when all Events of Default shall have been cured or waived, the
Issuer shall return to the Borrowers all amounts then on deposit with the Issuer
pursuant to this Section.  All amounts on deposit pursuant to this Section
shall, until their application to any Reimbursement Obligation or their return
to the Borrowers, as the case may be, bear interest at the daily average Federal
Funds Rate from time to time in effect (net of the costs of any reserve
requirements, in respect of amounts on deposit pursuant to this Section,
pursuant to F.R.S. Board Regulation D), which interest shall be held by the
Issuer as additional collateral security for the repayment of the Borrowers'
Obligations in connection with the Letters of Credit issued by the Issuer.

     SECTION 4.6. NATURE OF REIMBURSEMENT OBLIGATIONS. The Borrowers shall
assume all risks of the acts, omissions, or misuse of any Letter of Credit by
the beneficiary thereof. Neither the Lenders nor the Issuer (except to the
extent of its own gross negligence or wilful misconduct) shall be responsible
for:

          (a) the form, validity, sufficiency, accuracy, genuineness, or legal
     effect of any Letter of Credit or any document submitted by any party in
     connection with the application for and issuance of a Letter of Credit,
     even if it should in fact prove to be in any or all respects invalid,
     insufficient, inaccurate, fraudulent, or forged;

          (b) the form, validity, sufficiency, accuracy, genuineness, or legal
     effect of any instrument transferring or assigning or purporting to
     transfer or assign a Letter of Credit or the rights or benefits thereunder
     or proceeds thereof in whole or in part, which may prove to be invalid or
     ineffective for any reason;

          (c) failure of the beneficiary to comply fully with conditions
     required in order to demand payment under a Letter of Credit;

                                      -53-

 
          (d) errors, omissions, interruptions, or delays in transmission or
     delivery of any messages, by mail, cable, telegraph, telex, facsimile or
     otherwise; or

          (e) any loss or delay in the transmission or otherwise of any document
     or draft required in order to make a Disbursement under a Letter of Credit
     or of the proceeds thereof;

          (f) any change in the time, manner or place of payment of, or in any
     other term of, all or any of the obligations of the Borrowers in respect of
     any Letter of Credit;

          (g) the existence of any claim, set-off, defense or other right that
     the Borrowers may have at any time against any beneficiary or any
     transferee of any Letter of Credit (or any Person for whom any such
     beneficiary or any such transferee may be acting), the Issuer, the Lenders
     or any other Person, whether in connection with this Agreement, the
     transactions contemplated hereby or by the Letters of Credit or any
     unrelated transaction;

          (h) any payment by the Issuer, or the Lenders under any Letter of
     Credit against presentation of a draft or certificate that does not
     strictly comply with the terms of any Letter of Credit; or any payment made
     by the Issuer, or the Lenders under any Letter of Credit to any Person
     purporting to be a trustee in bankruptcy, debtor-in-possession, assignee
     for the benefit of creditors, liquidator, receiver or other representative
     of or successor to any beneficiary or any transferee of any Letter of
     Credit, including any arising in connection with any insolvency proceeding;
     and

          (i) any other circumstance or happening whatsoever, whether or not
     similar to any of the foregoing, including any other circumstance that
     might otherwise constitute a defense available to, or a discharge of, the
     Borrowers or a guarantor.

None of the foregoing shall affect, impair, or prevent the vesting of any of the
rights or powers granted the Lenders or the Issuer hereunder.  In furtherance
and extension, and not in limitation or derogation, of any of the foregoing, any
action taken or omitted to be taken by the Lenders or the Issuer in good faith
shall be binding upon the Borrowers and shall not put the Lenders or the Issuer
under any resulting liability to the Borrowers.

     SECTION 4.7. INCREASED COSTS; INDEMNITY. If by reason of

          (a) any change in Applicable Law or any change in the interpretation
     or application by any judicial or regulatory authority of any Applicable
     Law, or

                                      -54-

 
          (b) compliance by the Agent, the Issuer or any Lender with any
     direction, request or requirement (whether or not having the force of law)
     of any Governmental Agency, including Regulation D of the F.R.S. Board:

               (i)   the Agent, the Issuer or Lender shall be subject to any tax
          (other than taxes on net income and franchises), levy, charge or
          withholding of any nature or to any variation thereof or to any
          penalty with respect to the maintenance or fulfillment of its
          obligations under this Article IV, whether directly or by such being
          imposed on or suffered by the Agent, the Issuer or any Lender;

               (ii)  any reserve, deposit or similar requirement is or shall be
          applicable, increased, imposed or modified in respect of any Letters
          of Credit issued by any Issuer; or

               (iii) there shall be imposed on a Lender any other condition
          regarding this Article IV or any Letter of Credit,

and the result of the foregoing is directly or indirectly to increase the cost
to the Agent, the Issuer or any Lender of issuing or maintaining any Letter of
Credit or to reduce any amount receivable in respect thereof by the Agent, the
Issuer or any Lender, then and in any such case may, at any time after the
additional cost is incurred or the amount received is reduced, notify the
Borrowers thereof, and the Borrowers shall pay on demand such amounts as the
Agent, the Issuer or any Lender may specify to be necessary to compensate the
Agent, the Issuer or any Lender for such additional cost or reduced receipt,
together with interest on such amount from the date demanded until payment in
full thereof at a rate equal at all times to the Alternate Base Rate plus the
Applicable Margin plus 2% per annum.  The determination by the Agent, the Issuer
or any Lender, as the case may be, of any amount due pursuant to this Section,
as set forth in a statement setting forth the calculation thereof in reasonable
detail, shall, in the absence of manifest error, be final and conclusive and
binding on all of the parties hereto.

     In addition to amounts payable as elsewhere provided in this Article IV,
the Borrowers hereby indemnify, exonerate and hold the Agent, the Issuer or any
Lender harmless from and against any and all actions, causes of action, suits,
losses, costs, liabilities and damages, and expenses incurred in connection
therewith (irrespective of whether the Agent, the Issuer or any Lender is a
party to the action for which indemnification is sought), including reasonable
attorneys' fees and disbursements, which the Agent, the Issuer or any Lender may
incur or be subject to as a consequence, direct or indirect, of

                                      -55-

 
          (c) the issuance of the Letters of Credit, other than as a result of
     the gross negligence or wilful misconduct of the Issuer as determined by a
     court of competent jurisdiction, or

          (d) the failure of the Issuer to honor a drawing under any Letter of
     Credit as a result of any act or omission, whether rightful or wrongful, of
     any present or future de jure or de facto government or governmental
     authority.

                                  ARTICLE V.

                  CERTAIN INTEREST RATE AND OTHER PROVISIONS

     SECTION 5.1. LIBO RATE LENDING UNLAWFUL. If any Lender shall determine
(which determination shall, upon notice thereof to the Borrowers, be conclusive
and binding on the Borrowers) that the introduction of or any change in or in
the interpretation of any Applicable Law makes it unlawful, or any central bank
or other Governmental Agency asserts that it is unlawful, for such Lender to
make, continue or maintain any Loan as, or to convert any Loan into, a LIBO Rate
Loan, the obligation of the Lender to make, continue, maintain or convert into
any such LIBO Rate Loans shall, upon such determination, forthwith be suspended
until such Lender shall notify the Agent and the Borrowers that the
circumstances causing such suspension no longer exist, and all LIBO Rate Loans
shall automatically convert into Base Rate Loans at the end of the then current
Interest Periods with respect thereto or sooner, if required by such law or
assertion.

     SECTION 5.2. DEPOSITS UNAVAILABLE. If the Agent shall have determined that:

          (a) Dollar deposits in the relevant amount are not available to the
     Agent in its relevant market; or

          (b) by reason of circumstances affecting the Agent's relevant market,
     adequate means do not exist for ascertaining the interest rate applicable
     hereunder to LIBO Rate Loans,

then, upon notice from the Agent to the Borrowers and the Lenders, the
obligations of all Lenders under Section 2.3 to make any Loans shall forthwith
be suspended until the Agent shall notify the Borrowers and the Lenders that the
circumstances causing such suspension no longer exist.

     SECTION 5.3. INCREASED LOAN COSTS, ETC. If by reason of

          (a) any change in Applicable Law or any change in the interpretation
     or application by any judicial or regulatory authority of any Applicable
     Law, or

                                      -56-

 
          (b) compliance by any Lender with any direction, request or
     requirement (whether or not having the force of law) of any Governmental
     Agency, including Regulation D of the F.R.S. Board:

               (i)   any Lender shall be subject to any tax (other than taxes on
          net income and franchises), levy, charge or withholding of any nature
          or to any variation thereof or to any penalty with respect to any
          payment due under any LIBO Rate Loan or other amounts due under this
          Agreement, whether directly or by such being imposed on or suffered by
          such Lender;

               (ii)  any reserve, deposit or similar requirement is or shall be
          applicable, increased, imposed or modified in respect of any
          extensions of credit or other assets of, or any deposits with or other
          liabilities of, any Lender or Loans made by such Lender, or against
          any other funds, obligations or other property owned or held by such
          Lender and such Lender actually incurs such additional costs; or

               (iii) there shall be imposed on any Lender any other condition
          affecting this Agreement (or any of such extensions of credit or
          liabilities),

and the result of the foregoing is directly or indirectly to increase the cost
to such Lender of making, continuing or maintaining (or of its obligation to
make, continue or maintain) any Loans as, or of converting (or of its obligation
to convert) any Loans into, LIBO Rate Loans, or to reduce any amount receivable
in respect thereof by such Lender, then and in any such case such Lender may, at
any time after the additional cost is incurred or the amount received is
reduced, notify the Borrowers thereof, and the Borrowers shall pay on demand
such amounts as such Lender may specify to be necessary to compensate such
Lender for such additional cost or reduced receipt, together with interest on
such amount from the date demanded until payment in full thereof at a rate equal
at all times to the Alternate Base Rate plus the Applicable Margin, plus 3% per
annum.  The determination by such Lender of any amount due pursuant to this
Section, as set forth in a statement setting forth the calculation thereof in
reasonable detail, shall, in the absence of manifest error, be final and
conclusive and binding on all of the parties hereto.

     SECTION 5.4. FUNDING LOSSES. In the event any Lender shall incur any loss
or expense (including any loss or expense incurred by reason of the liquidation
or reemployment of deposits or other funds acquired by such Lender to make,
continue or maintain any portion of the principal amount of any Loan as, or to
convert any portion of the principal amount of any Loan into, a LIBO Rate Loan)
as a result of

                                      -57-

 
          (a) any conversion or repayment or prepayment of the principal amount
     of any LIBO Rate Loans on a date other than the scheduled last day of the
     Interest Period applicable thereto, whether pursuant to Section 3.1 or
     otherwise;

          (b) any Loans not being made as LIBO Rate Loans in accordance with the
     Borrowing Request therefor by reason of any act or omission by the
     Borrowers or failure of a condition precedent to be satisfied;

          (c) any Loans not being continued as, or converted into, LIBO Rate
     Loans in accordance with the Continuation/ Conversion Notice therefor by
     reason of any act or omission by the Borrowers; or

          (d) any repayment or prepayment of the principal amount of any Loans
     on a date other than the scheduled Monthly Payment Dates;

then, upon the written notice of such Lender to the Borrowers (with a copy to
the Agent), the Borrowers shall, within five (5) days of its receipt thereof,
pay to such Lender such amount as will (in the reasonable determination of such
Lender) reimburse such Lender for such loss or expense.  Such written notice
(which shall include calculations in reasonable detail) shall, in the absence of
manifest error, be conclusive and binding on the Borrowers.

     SECTION 5.5. INCREASED CAPITAL COSTS. If any change in, or the
introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in of, any Applicable Law of any Governmental Agency 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, issuance of Letters of
Credit or the Loans made by such Lender is reduced to a level below that which
such Lender or such controlling Person could have achieved but for the
occurrence of any such circumstance, then, in any such case upon notice from
time to time by such Lender to the Borrowers, the Borrowers 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 Borrowers. In determining such amount,
such Lender may use any method of averaging and attribution that it (in its
reasonable discretion) shall deem applicable.

     SECTION 5.6. TAXES. All payments by the Borrowers of principal of, and
interest on, the Loans and all other amounts payable hereunder shall be made
free and clear of and without deduction for any present or future income,
excise, stamp 

                                      -58-

 
or franchise taxes and other taxes, levies, assessments, imposts, deductions,
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 Lender's 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 Borrowers hereunder is required in respect of any Taxes
pursuant to any Applicable Law, then the Borrowers will

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

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

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

Moreover, if any Taxes are directly asserted against any Lender with respect to
any payment received by such Lender hereunder, such Lender may pay such Taxes
and the Borrowers 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 Borrowers fail to pay any Taxes when due to the appropriate taxing
authority or fail to remit to any Lender the required receipts or other required
documentary evidence, the Borrowers shall indemnify such Lender for any
incremental Taxes, interest or penalties that may become payable by such Lender
as a result of any such failure.

     SECTION 5.7. PAYMENTS, COMPUTATIONS, ETC. Unless otherwise expressly
provided, all payments by the Borrowers pursuant to this Agreement, the Notes or
any other Loan Document shall be made by the Borrowers to the Agent for the pro
rata account of the Lenders entitled to receive such payment. All such payments
shall be made without setoff, deduction or counterclaim, not later than 11:00
a.m. (Chicago time) on the date due, in same day or immediately available funds,
to such account with the Agent in Chicago, Illinois as the Agent shall specify
from time to time by notice to the Borrowers. Funds received after that time
shall be deemed to have been received by the Agent on the next succeeding
Business Day and any applicable interest or fee shall continue to accrue. The
Agent shall promptly remit in 

                                      -59-

 
same day funds to each Lender its share, if any, of such payments received by
the Agent for the account of such Lender. All interest shall be computed on the
basis of the actual number of days (including the first day but excluding the
last day) occurring during the period for which such interest is payable over a
year comprised of 360 days (or, in the case of interest on a Base Rate Loan
(other than when calculated with respect to the Federal Funds Rate), 365 days
or, if appropriate, 366 days). Whenever any payment to be made shall otherwise
be due on a day which is not a Business Day, such payment shall (except as
otherwise required by clause (c) of the definition of the term "Interest Period"
with respect to LIBO Rate Loans) be made on the next succeeding Business Day and
such extension of time shall be included in computing interest and fees, if any,
in connection with such payment. Notwithstanding any prepayment of a Base Rate
Loan or any conversion of a Base Rate Loan to a LIBO Rate Loan, the Agent will
calculate and invoice the Borrowers for accrued interest thereon through the
date of such prepayment only at the next Quarterly Payment Date.

     SECTION 5.8. SHARING OF PAYMENTS. If any Lender shall obtain any payment or
other recovery (whether voluntary, involuntary, by application of setoff or
otherwise) on account of any Loan (other than pursuant to the terms of Sections
5.3, 5.4 and 5.5) in excess of its pro rata share of payments then or therewith
obtained by all Lenders, such Lender shall purchase from the other Lenders such
participations in Loans made by them and/or Letters of Credit as shall be
necessary to cause such purchasing Lender to share the excess payment or other
recovery ratably with each of them; provided, however, that if all or any
portion of the excess payment or other recovery is thereafter recovered from
such purchasing Lender, the purchase shall be rescinded and each Lender which
has sold a participation to the purchasing Lender shall repay to the purchasing
Lender the purchase price to the ratable extent of such recovery together with
an amount equal to such selling Lender's ratable share (according to the
proportion of

          (a) the amount of such selling Lender's required repayment to the
     purchasing Lender

to

          (b) the total amount so recovered from the purchasing Lender)

of any interest or other amount paid by the purchasing Lender in respect of the
total amount so recovered.  The Borrower agrees that any Lender so purchasing a
participation from another Lender pursuant to this Section may, to the fullest
extent permitted by law, exercise all its rights of payment (including pursuant
to Section 5.9) with respect to such participation as fully as if such Lender
were the direct creditor of the Borrower in the amount of such participation.
If under any applicable bankruptcy, insolvency or other similar law, any Lender
receives a secured claim in 

                                      -60-

 
lieu of a setoff to which this Section applies, such Lender shall, to the extent
practicable, exercise its rights in respect of such secured claim in a manner
consistent with the rights of the Lenders entitled under this Section to share
in the benefits of any recovery on such secured claim.

     SECTION 5.9.  SETOFF. Each Lender shall, upon the occurrence of any Default
described in clauses (a) through (d) of Section 9.1.9 or upon the occurrence of
any other Event of Default, have the right to appropriate and apply to the
payment of the Obligations owing to it (whether or not then due), and (as
security for such Obligations) the Borrowers hereby grant to the Agent and the
Lenders a continuing security interest in, any and all balances, credits,
deposits, accounts or moneys of the Borrowers then or thereafter maintained with
or otherwise held by the Lender, including without limitation, the Proceeds
Account. The Agent and the Lenders agree promptly to notify the Borrowers after
any such setoff and application made by the Lender; provided, however, that the
failure to give such notice shall not affect the validity of such setoff and
application. The rights of the Agent and each Lender under this Section 5.9 are
in addition to other rights and remedies (including other rights of setoff under
Applicable Law or otherwise) which the Agent and the Lenders may have.

     SECTION 5.10. USE OF PROCEEDS. The Borrowers shall apply the proceeds of
each Borrowing in accordance with Section 2.7; without limiting the foregoing,
no proceeds of any Loan will be used to acquire any equity security of a class
which is registered pursuant to Section 12 of the Securities Exchange Act of
1934 or any "margin stock", as defined in F.R.S. Board Regulation U, X or G.

                                  ARTICLE VI.

          common law theories relating to operations or the condition of any
          facilities or Property (including underlying groundwater) owned,
          leased or operated by the Borrowers or any of their Subsidiaries that,

Effect.

                                   ARTICLE X

                                   THE AGENT

     SECTION  10.1.  ACTIONS.  Each Lender hereby appoints BankAmerica as its
Agent under and for purposes of this Agreement, the Notes and each other Loan
Document, and BankAmerica hereby accepts such appointment.  Each Lender
authorizes the Agent to act on behalf of such Lender under this Agreement, the
Notes and each other Loan Document and, in the absence of other written
instructions from the Required Lenders received from time to time by the Agent
(with respect to which the Agent agrees that it will comply, except as otherwise
provided in this Section and to the extent such instructions may reasonably be
expected to comply with applicable law), to exercise such powers and to perform
such duties hereunder and thereunder as are specifically delegated to or
required of the Agent by the terms hereof and 

                                      -96-

 
thereof, together with such powers as may be reasonably incidental thereto;
provided, however, that the Agent shall not take any action that requires the
consent of any Lender unless it receives such consent. Each Lender hereby
indemnifies (which indemnity shall survive any termination of this Agreement)
the Agent, pro rata according to such Lender's Percentage, from and against any
and all liabilities, obligations, losses, damages, claims, costs or expenses of
any kind or nature whatsoever which may at any time be imposed on, incurred by,
or asserted against, the Agent in any way relating to or arising out of this
Agreement, the Notes and any other Loan Document, including reasonable
attorneys' fees, and as to which the Agent is not reimbursed by the Borrowers;
provided, however, that no Lender shall be liable for the payment of any portion
of such liabilities, obligations, losses, damages, claims, costs or expenses
which are determined by a court of competent jurisdiction in a final proceeding
to have resulted solely from the Agent's gross negligence or wilful misconduct.
The Agent shall not be required to take any action hereunder, under the Notes or
under any other Loan Document, or to prosecute or defend any suit in respect of
this Agreement, the Notes or any other Loan Document, unless it is indemnified
hereunder to its satisfaction. If any indemnity in favor of the Agent shall be
or become, in the Agent's determination, inadequate, the Agent may call for
additional indemnification from the Lenders and cease to do the acts indemnified
against hereunder until such additional indemnity is given.

     SECTION  10.2.  FUNDING RELIANCE, ETC.  Unless the Agent shall have been
notified by telephone, confirmed in writing, by any Lender by 5:00 p.m. (Chicago
time) on the day prior to a Borrowing that such Lender will not make available
the amount which would constitute its Percentage of such Borrowing on the date
specified therefor, the Agent may assume that such Lender has made such amount
available to the Agent and, in reliance upon such assumption, make available to
the Borrower a corresponding amount.  If and to the extent that such Lender
shall not have made such amount available to the Agent, such Lender and the
Borrower severally agree to repay the Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
the Agent made such amount available to the Borrowers to the date such amount is
repaid to the Agent, at the interest rate applicable at the time to Loans
comprising such Borrowing.

     SECTION  10.3.  EXCULPATION.  Neither the Agent nor any of its directors,
officers, employees or agents shall be liable to any Lender for any action taken
or omitted to be taken by it under this Agreement or any other Loan Document, or
in connection herewith or therewith, except for its own wilful misconduct or
gross negligence, nor responsible for any recitals or warranties herein or
therein, nor for the effectiveness, enforceability, validity or due execution of
this Agreement or any other Loan Document, nor for the creation, perfection or
priority of any Liens purported to be created by any of the Loan Documents, or
the validity, genuineness, enforceability, existence, value or sufficiency of
any collateral security, nor to make any inquiry respecting the performance by
the Borrowers of their obligations hereunder or under 

                                      -97-

 
any other Loan Document. Any such inquiry which may be made by the Agent shall
not obligate it to make any further inquiry or to take any action. The Agent
shall be entitled to rely upon advice of counsel concerning legal matters and
upon any notice, consent, certificate, statement or writing which the Agent
believes to be genuine and to have been presented by a proper Person.

     SECTION  10.4.  SUCCESSOR.  The Agent may resign as such at any time upon
at least thirty (30) days' prior notice to the Borrowers and all Lenders, and
the Agent may be removed with or without cause as such by the Required Lenders
upon at least thirty (30) days' prior notice to the Agent and the Borrowers. If
the Agent at any time shall resign or be removed, the Required Lenders may
appoint another Lender as a successor Agent with the consent of the Borrowers
(which consent shall not be unreasonably withheld) which shall Lender thereupon
become the Agent hereunder. If no successor Agent shall have been so appointed
by the Required Lenders, and shall have accepted such appointment, within thirty
(30) days after the giving of notice of resignation or removal, then the
retiring or removed Agent may with the consent of the Borrowers (which consent
shall not be unreasonably withheld), on behalf of the Lenders, appoint a
successor Agent, which shall be one of the Lenders and, if no Lender accepts
such appointment, a commercial banking institution organized under the laws of
the United States (or any State thereof) or a United States branch or agency of
a commercial banking institution, and having a combined capital and surplus of
at least $500,000,000. Upon the acceptance of any appointment as Agent hereunder
by a successor Agent, such successor Agent shall be entitled to receive from the
retiring or removed Agent such documents of transfer and assignment as such
successor Agent may reasonably request, and shall thereupon succeed to and
become vested with all rights, powers, privileges and duties of the retiring or
removed Agent, and the retiring or removed Agent shall be discharged from its
duties and obligations under this Agreement. After any retiring or removed
Agent's resignation or removal hereunder as the Agent, the provisions of

          (a) this Article X shall inure to its benefit as to any actions taken
     or omitted to be taken by it while it was the Agent under this Agreement;
     and

          (b) Section 11.3 and Section 11.4 shall continue to inure to its
     benefit.

     SECTION  10.5.  LOANS OR LETTERS OF CREDIT ISSUED BY BANKAMERICA. 
BankAmerica shall have the same rights and powers with respect to (x) the Loans
made by it or any of its Affiliates, (y) the Notes held by it or any of its
Affiliates, and (z) its participating interests in the Letters of Credit as any
other Lender and may exercise the same as if it were not the Agent. BankAmerica
and its Affiliates and each of the Lenders and their respective Affiliates may
accept deposits from, lend money to, and generally engage in any kind of
business with the Borrowers or any Subsidiary or Affiliate of the Borrowers as
if BankAmerica were not the Agent

                                      -98-

 
hereunder and in the case of each Lender, as if such Lender were not a Lender
hereunder.

     SECTION  10.6.  CREDIT DECISIONS.  Each Lender acknowledges that it has,
independently of the Agent and each other Lender, and based on such Lender's
review of the financial information of the Borrowers, this Agreement, the other
Loan Documents (the terms and provisions of which being satisfactory to such
Lender) and such other documents, information and investigations as such Lender
has deemed appropriate, made its own credit decision to extend its Commitments.
Each Lender also acknowledges that it will, independently of the Agent and each
other Lender, and based on such other documents, information and investigations
as it shall deem appropriate at any time, continue to make its own credit
decisions as to exercising or not exercising from time to time  any rights and
privileges available to it under this Agreement or any other Loan Document.

     SECTION  10.7.  COPIES, ETC.  The Agent shall give prompt notice to each
Lender of each notice or request required or permitted to be given to the Agent
by the Borrowers pursuant to the terms of this Agreement (unless concurrently
delivered to the Lenders by the Borrowers).  The Agent will distribute promptly
to each Lender each document or instrument received for its account and copies
of all other communications received by the Agent from the Borrowers for
distribution to the Lenders by the Agent in accordance with the terms of this
Agreement.


                                  ARTICLE XI.

                           MISCELLANEOUS PROVISIONS

     SECTION  11.1.  WAIVERS, AMENDMENTS, ETC.

          (a)  The provisions of this Agreement and of each other Loan Document
     may from time to time be amended, modified or waived, if such amendment,
     modification or waiver is in writing and consented to by the Borrowers and
     the Agent; provided, however, that no such amendment, modification or
     waiver which would:

               (i) modify any requirement hereunder that any particular action
          be taken by all the Lenders or by the Required Lenders shall be
          effective unless consented to by each Lender;

               (ii) modify this Section 11.1, change the definitions of
          "Required Lenders" or "Commitment Amount", increase the Percentage of
          any Lender, reduce any fees described in Article III, change the
          amortization schedule  provided for in Section 3.1.1(e), (f) or (g),
          release 

                                      -99-

 
          all or substantially all collateral security, except as otherwise
          specifically provided in any Loan Document, or extend the Tranche A
          Availability Termination Date, the Tranche B Availability Termination
          Date, any Stated Maturity Date or the Commitment Termination Date,
          shall be made without the consent of each Lender;

               (iii) extend the due date for, or reduce the amount of, any
          scheduled or mandatory repayment or prepayment of principal of or
          interest on any Loan (or reduce the principal amount of or rate of
          interest on any Loan) shall be made without the consent of each
          Lender;

               (iv)  affect adversely the interests, rights or obligations of an
          Issuer in its capacity as Issuer shall be made without the consent of
          such Issuer; or

               (v)   affect adversely the interests, rights or obligations of
          the Agent in its capacity as the Agent shall be made without consent
          of the Agent.

     No failure or delay on the part of the Agent or the Lenders in exercising
     any power or right under this Agreement or any other Loan Document shall
     operate as a waiver thereof, nor shall any single or partial exercise of
     any such power or right preclude any other or further exercise thereof or
     the exercise of any other power or right.  No notice to or demand on the
     Borrowers in any case shall entitle it to any notice or demand in similar
     or other circumstances.  No waiver or approval by the Agent under this
     Agreement or any other Loan Document shall, except as may be otherwise
     stated in such waiver or approval, be applicable to subsequent
     transactions.  No waiver or approval hereunder shall require any similar or
     dissimilar waiver or approval thereafter to be granted hereunder.

          (b)  This Agreement is an amendment and restatement of, and replaces
     and supersedes the Existing Agreement; provided, however, that no right,
     interest, claim or cause of action of any kind of the Agent or any Lender
     which may have existed under the Existing Agreement shall in any way be
     released, modified, compromised or waived by virtue of this Existing
     Agreement superseding and replacing the Existing Agreement.

     SECTION  11.2.  NOTICES.

          (a) All notices, requests, consents, approvals, waivers and other
     communications shall be in writing (including, unless the context expressly
     otherwise provides, by facsimile transmission, provided that any matter
     transmitted by the Borrowers by facsimile (i) shall be immediately
     confirmed by

                                     -100-

 
     a telephone call to the recipient at the number specified on the signature
     pages, and (ii) shall be followed promptly by delivery of a hard copy
     original thereof) and mailed, faxed or delivered, to the address or
     facsimile number specified for notices on the signature pages hereof; or,
     as directed to the Borrowers or the Lenders, to such other address as shall
     be designated by such party in a written notice to the other parties, and
     as directed to any other party, at such other address as shall be
     designated by such party in a written notice to the Borrowers and the
     Lenders.

          (b) All such notices, requests and communications shall, when
     transmitted  by  overnight  delivery,  or  faxed, be effective when
     delivered for overnight (next-day) delivery, or transmitted in legible form

     delivery.

          (c) Any agreement of the Lenders herein to receive certain notices by
     telephone or facsimile is solely for the convenience and at the request of
     the Borrowers.  The Agent and the Lenders shall be entitled to rely on the
     authority of any Person purporting to be a Person authorized by the
     Borrowers to give such notice and the Agent and the Lenders shall not have
     any liability to the Borrowers or other Person on account of any action
     taken or not taken by the Agent and the Lenders in reliance upon such
     telephonic or facsimile notice.  The obligation of the Borrowers to repay
     the Loans shall not be affected in any way or to any extent by any failure
     by a Lender to receive written confirmation of any telephonic or facsimile
     notice or the receipt by the Agent and the Lenders of a confirmation which
     is at variance with the terms understood by the Agent and the Lenders to be
     contained in the telephonic or facsimile notice.

     SECTION  11.3.  PAYMENT OF COSTS AND EXPENSES.  The Borrowers agree to pay
on demand all reasonable expenses of the Agent and each Lender (including the
fees and out-of-pocket expenses of internal and external counsel to the Agent
and each Lender and of local counsel, if any, who may be retained by counsel to
the Agent) in connection with

          (a) the negotiation, preparation, execution and delivery of this
     Agreement and of each other Loan Document, including schedules and
     exhibits, and any amendments, waivers, consents, supplements or other
     modifications to this Agreement or any other Loan Document as may from time
     to time hereafter be required, whether or not the transactions contemplated
     hereby are consummated,

          (b) the filing, recording, refiling or rerecording of the Mortgages,
     the Security Agreements, the Pledge Agreements and/or any Uniform
     Commercial Code financing statements relating thereto and all amendments,
     supplements,

                                     -101-

 
     and modifications to, and all releases and terminations of, any thereof and
     any and all other documents or instruments of further assurance required to
     be filed or recorded or refiled or rerecorded by the terms hereof or of the
     Mortgages, the Security Agreements and the Pledge Agreements, and

          (c) the preparation and review of the form of any document or
     instrument relevant to this Agreement or any other Loan Document.

The Borrowers further agree to pay, and to save the Agent and each Lender
harmless from all liability for, any stamp or other taxes which may be payable
in connection with the execution or delivery of this Agreement, the borrowings
hereunder, the issuance of the Notes, the issuance of the Letters of Credit, or
any other Loan Documents.  The Borrowers also agree to reimburse the Agent and
each Lender upon demand for all reasonable out-of-pocket expenses (including
attorneys' fees and legal expenses of internal and external attorneys) incurred
by the Agent and each Lender in connection with (x) the negotiation of any
restructuring or "work-out", whether or not consummated, of any Obligations and
(y) the enforcement of any Obligations.

     SECTION  11.4.  INDEMNIFICATION.  In consideration of the execution and
delivery of this Agreement by the Agent and each Lender and the extension of the
Commitments, the Borrowers hereby indemnify, exonerate and hold the Agent and
each Lender and each of its officers, directors, employees and agents
(collectively, the "Indemnified Parties") free and harmless from and against any
and all actions, causes of action, suits, losses, costs, liabilities and
damages, and expenses incurred in connection therewith (irrespective of whether
any such Indemnified Party is a party to the action for which indemnification
hereunder is sought), including reasonable attorneys' fees and disbursements
(collectively, the "Indemnified Liabilities"), incurred by the Indemnified
Parties or any of them as a result of, or arising out of, or relating to

          (a) This Agreement, any Loan Document or any document contemplated
     hereby or referred to herein;

          (b) any transaction financed or to be financed in whole or in part,
     directly or indirectly, with the proceeds of any Loan, including the
     transactions contemplated by the Difco Agreement and the Burlington
     Agreement, any Approved Development Activities, or the use of any Letter of
     Credit;

          (c) any investigation, litigation or proceeding related to any
     acquisition or proposed acquisition by any Borrower or any of their
     Subsidiaries of all or any portion of the stock or assets of any Person,
     whether or not the Agent and each Lender is party thereto;

                                     -102-

 
          (d) 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 any Borrower or any of their Subsidiaries;

          (e) 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 any Borrower or any of their
     Subsidiaries 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, such Borrower or any of their Subsidiaries; or

          (f) any misrepresentation, inaccuracy or breach in or of Section 7.17
     or Section 8.1.6,

except for any such Indemnified Liabilities arising for the account of a
particular Indemnified Party by reason of the relevant Indemnified Party's gross
negligence or wilful misconduct.  If and to the extent that the foregoing
undertaking may be unenforceable for any reason, the Borrowers hereby agree to
make the maximum contribution to the payment and satisfaction of each of the
Indemnified Liabilities which is permissible under Applicable Law.  The
obligations in this Section 11.4 shall survive payment of all other Obligations.
At the election of any Indemnified Party, the Borrowers shall defend such
Indemnified Party using legal counsel satisfactory to such Indemnified Party in
such Person's sole discretion, at the sole cost and expense of the Borrowers.
All amounts owing under this Section 11.4 shall be paid within thirty (30) days
after demand.

     SECTION  11.5.  SURVIVAL.  The obligations of the Borrowers under Sections
5.3, 5.4, 5.5, 5.6, 11.3 and 11.4 shall in each case survive any termination of
this Agreement, the payment in full of all Obligations and the termination of
all Commitments.  The representations and warranties made by each Obligor in
this Agreement and in each other Loan Document shall survive the execution and
delivery of this Agreement and each such other Loan Document.

     SECTION  11.6.  SEVERABILITY.  Any provision of this Agreement or any other
Loan Document which is prohibited or unenforceable in any jurisdiction shall, as
to such provision and such jurisdiction, be ineffective to the extent of such
prohibition or unenforceability without invalidating the remaining provisions of
this Agreement or such Loan Document or affecting the validity or enforceability
of such provision in any other jurisdiction.

     SECTION  11.7.  HEADINGS.  The various headings of this Agreement and of
each other Loan Document are inserted for convenience only and shall not affect

                                     -103-

 
the meaning or interpretation of this Agreement or such other Loan Document or
any provisions hereof or thereof.

     SECTION  11.8.  EXECUTION IN COUNTERPARTS, EFFECTIVENESS, ETC.  This
Agreement may be executed by the parties hereto in several counterparts, each of
which shall be executed by the Agent, the Borrowers and the Lenders and be
deemed to be an original and all of which shall constitute together but one and
the same agreement. This Agreement shall become effective when counterparts
hereof are executed on behalf of the Agent, the Borrowers and the Lenders.  This
Agreement is made and entered into for the sole protection and legal benefit of
the Agent, the Borrowers and the Lenders and Persons indemnified hereunder, and
their permitted successors and assigns, and no other Person shall be a direct or
indirect legal beneficiary of, or have any direct or indirect cause of action or
claim in connection with, this Agreement or any of the other Loan Documents.

     SECTION  11.9.  GOVERNING LAW; ENTIRE AGREEMENT.  THIS AGREEMENT, THE NOTE
AND EACH OTHER LOAN DOCUMENT (OTHER THAN THE MORTGAGES OR AS EXPRESSLY PROVIDED
IN ANY SUCH DOCUMENT) SHALL EACH BE DEEMED TO BE A CONTRACT MADE UNDER AND
GOVERNED BY THE INTERNAL LAWS OF THE STATE OF ILLINOIS.  This Agreement, the
Note and the other Loan Documents constitute the entire understanding among the
parties hereto with respect to the subject matter hereof and supersede any prior
agreements, written or oral, with respect thereto.

     SECTION  11.10.  SUCCESSORS AND ASSIGNS.  This Agreement shall be binding
upon and shall inure to the benefit of the parties hereto and their respective
successors and assigns; provided, however, that:

          (a) the Borrowers may not assign or transfer their rights or
     obligations hereunder without the prior written consent of the Agent and
     all Lenders; and

          (b) the rights of sale, assignment and transfer of the Lenders are
     subject to Section 11.11.

     SECTION  11.11.  SALE AND TRANSFER OF LOANS AND NOTE; PARTICIPATIONS IN 
LOANS AND NOTE.  Each Lender may assign, or sell participations in, its Loans
and Commitments to one or more other Persons in accordance with this Section
11.11.

     SECTION  11.11.1.  ASSIGNMENTS.  A Lender may at any time assign and
delegate to one or more Persons, including without limitation, banks or other
financial institutions (each Person to whom such assignment and delegation is to
be made, being hereinafter referred to as an "Assignee Lender"), all or any
fraction of such Lender's total Loans and Commitments (which assignment and
delegation shall be of a constant, and not a varying, percentage of all such
Lender's Loans and Commitments) in a minimum aggregate amount of $1,000,000 (or
the entire remaining amount of such Lender's Loans and

                                     -104-

 
Commitments); provided, however, that such Lender is required at all times to
maintain Loans, Letter of Credit Outstandings and Commitments hereunder in an
aggregate amount of $1,000,000 (unless such Lender shall have reduced its Loans,
Letter of Credit Outstandings and Commitments to zero); provided, further,
however, that the Borrowers and each other Obligor shall be entitled to continue
to deal solely and directly with such Lender in connection with the interests so
assigned and delegated to an Assignee Lender until

          (a) written notice of such assignment and delegation, together with
     payment instructions, addresses and related information with respect to
     such Assignee Lender, shall have been given to the Borrowers by such Lender
     and such Assignee Lender,

          (b) such Assignee Lender shall have executed and delivered to the
     Borrowers the Agent and such Lender a Lender Assignment Notice, accepted by
     such Lender and the Agent, and

          (c) the processing fees described below shall have been paid.

From and after the date that the Assignee Lender delivers such Lender Assignment
Notice, (x) the Assignee Lender thereunder shall be deemed automatically to have
become a party hereto and to the extent that rights and obligations hereunder
have been assigned and delegated to such Assignee Lender in connection with such
Lender Assignment Notice, shall have the rights and obligations of a Lender
hereunder and under the other Loan Documents, and (y) the assignor Lender, to
the extent that rights and obligations hereunder have been assigned and
delegated by it in connection with such Lender Assignment Notice, shall be
released from its obligations hereunder and under the other Loan Documents.
Within five (5) Business Days after its receipt of notice that the Lender has
received an executed Lender Assignment Notice, the Borrowers shall execute and
deliver to the relevant Assignee Lender a new Note evidencing such Assignee
Lender's assigned Loans and Commitments and, if the assignor Lender has retained
Loans and Commitments hereunder, a replacement Note in the principal amount of
the Loans and Commitments retained by the assignor Lender hereunder (each such
Note to be in exchange for, but not in payment of, the corresponding Note then
held by such assignor Lender).  The assignor Lender shall mark the predecessor
Note "exchanged" and deliver it to the Borrowers.  Accrued interest on that part
of the predecessor Note evidenced by the new Notes, and accrued fees, shall be
paid as provided in the Lender Assignment Notice.  Accrued interest on that part
of the predecessor Note evidenced by the replacement Notes shall be paid to the
assignor Lender.  Accrued interest and accrued fees shall be paid at the same
time or times provided in the predecessor Notes and in this Agreement.  Such
assignor Lender or such Assignee Lender must also pay a processing fee to the
Lender upon delivery of any Lender Assignment Notice in the amount of $2,500.
Any 

                                     -105-

 
attempted assignment and delegation not made in accordance with this Section
11.11.1 shall be null and void.  Nothing contained in this Agreement shall
prohibit any Lender from pledging or assigning any Note to any Federal Reserve
Bank in accordance with Applicable Law.

     SECTION  11.11.2.  PARTICIPATIONS.  A Lender may at any time sell to one or
more Persons, including without limitation, commercial banks or other Persons
(each of such commercial banks and other Persons being herein called a
"Participant") participating interests in any of the Loans, Commitments, or
other interests of such Lender hereunder; provided, however, that

          (a) no participation contemplated in this Section 11.11 shall relieve
     such Lender from its Commitments or its other obligations hereunder or
     under any other Loan Document,

          (b) such Lender shall remain solely responsible for the performance of
     its Commitments and such other obligations,

          (c) the Borrowers and each other Obligor shall continue to deal solely
     and directly with such Lender in connection with such Lender's rights and
     obligations under this Agreement and each of the other Loan Documents, and

          (d) the Borrowers shall not be required to pay any amount under
     Section 4.6 that is greater than the amount which it would have been
     required to pay had no participating interest been sold.

The Borrowers acknowledge and agree that each Participant, for purposes of
Sections 5.3, 5.4, 5.5 and 5.6 (except as provided in Section 11.11.2(d)), 5.8,
11.3 and 11.4, shall be considered a Lender.

     SECTION  11.12.  FORUM SELECTION AND CONSENT TO JURISDICTION.  ANY
LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS
AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF
DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE LENDERS, THE
AGENT OR THE BORROWERS SHALL BE BROUGHT AND MAINTAINED IN THE COURTS OF THE
STATE OF ILLINOIS OR IN THE UNITED STATES DISTRICT COURT FOR THE NORTHERN
DISTRICT OF ILLINOIS; PROVIDED, HOWEVER, THAT ANY SUIT SEEKING ENFORCEMENT
AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT THE AGENT'S OPTION,
IN THE COURTS OF ANY JURISDICTION WHERE SUCH COLLATERAL OR OTHER PROPERTY MAY BE
FOUND. THE BORROWERS HEREBY EXPRESSLY AND IRREVOCABLY SUBMIT TO THE JURISDICTION
OF THE COURTS OF THE STATE OF ILLINOIS AND OF THE UNITED STATES DISTRICT COURT
FOR THE NORTHERN DISTRICT OF ILLINOIS FOR THE PURPOSE OF ANY SUCH LITIGATION AS
SET

                                     -106-

 
FORTH ABOVE AND IRREVOCABLY AGREE TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY
IN CONNECTION WITH SUCH LITIGATION.  THE BORROWERS FURTHER IRREVOCABLY CONSENT
TO THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL
SERVICE WITHIN OR WITHOUT THE STATE OF ILLINOIS.  THE BORROWERS HEREBY EXPRESSLY
AND IRREVOCABLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION
WHICH THEY MAY HAVE OR HEREAFTER MAY HAVE TO THE LAYING OF VENUE OF ANY SUCH
LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY
SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.  TO THE EXTENT THAT
THE BORROWERS HAVE OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF
ANY COURT OR FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE,
ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH
RESPECT TO ITSELF OR ITS PROPERTY, THE BORROWERS HEREBY IRREVOCABLY WAIVE SUCH
IMMUNITY IN RESPECT OF ITS OBLIGATIONS UNDER THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS.

     SECTION  11.13.  WAIVER OF JURY TRIAL.  THE AGENT, THE LENDERS AND THE
BORROWERS HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHTS THEY
MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR
ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN
DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER ORAL
OR WRITTEN) OR ACTIONS OF THE LENDERS, THE AGENT OR THE BORROWERS.  THE
BORROWERS ACKNOWLEDGE AND AGREE THAT THEY HAVE RECEIVED FULL AND SUFFICIENT
CONSIDERATION FOR THIS PROVISION (AND EACH OTHER PROVISION OF EACH OTHER LOAN
DOCUMENT TO WHICH THEY ARE A PARTY) AND THAT THIS PROVISION IS A MATERIAL
INDUCEMENT FOR THE LENDERS ENTERING INTO THIS AGREEMENT AND EACH SUCH OTHER LOAN
DOCUMENT.

     SECTION  11.14.  JOINT AND SEVERAL LIABILITY.  Each Borrower has determined
that it is in its best interest and in pursuit of its legitimate business
purposes to induce the Lenders to extend credit to the Borrowers pursuant to
this Agreement.  Each Borrower acknowledges and represents that its business is
integrally related to the business of the other Borrowers, that the availability
of the Commitments to all of the Borrowers benefits each Borrower individually
and that the Loans made will be for and inure to the benefit of all of the
Borrowers individually and as a group.  Accordingly, each Borrower shall be
jointly and severally liable (as a principal and not as a surety, guarantor or
other accommodation party) for each and every representation, warranty, covenant
and obligation to be performed by the Borrowers under this Agreement, the Notes
and the other Loan Documents, and each Borrower acknowledges that in extending
the credit provided herein the Lenders are relying upon the fact that the
obligations of each Borrower hereunder are the joint and several obligations of
a principal.  The invalidity, unenforceability or illegality of this 

                                     -107-

 
Agreement, the Note or any other Loan Document as to one Borrower or the release
by the Agent or any Lender of a Borrower hereunder or thereunder shall not
affect the obligations of the other Borrowers under this Agreement, the Note or
other Loan Documents, all of which shall otherwise remain valid and legally
binding obligations of the other Borrowers.

     SECTION  11.15.  CERTAIN CONSENTS AND WAIVERS.

          (a) The Agent or any Lender may, at any time and from time to time,
     without the consent of or notice to the Borrowers, except such notice as
     may be required by applicable statute which cannot be waived, without
     incurring responsibility to the Borrowers, and without impairing or
     releasing the obligations of the Borrowers in whole or in part, (i)
     exercise or refrain from exercising any rights against any Borrower, (ii)
     sell, exchange, release, surrender, realize upon or otherwise deal with in
     any manner or in any order any property pledged or mortgaged to secure or
     in any manner securing the Obligations, (iii) take and hold any additional
     security for any or all of the Obligations, (iv) apply any sums by
     whomsoever paid or howsoever realized to any Obligations of the Borrowers
     to the Lenders regardless of what Obligations remain unpaid.

          (b) No invalidity, irregularity or unenforceability of the Obligations
     of a Borrower under this Agreement or any other Loan Document shall affect,
     impair or be a defense to the other Borrowers' Obligations.  Each Borrower
     hereby waives, to the extent permitted under Applicable Law, any and all
     benefits and defenses under any statute, regulation, judicial decision or
     other law which purports to exonerate or reduce the liability of a co-
     borrower as a result of any disability or absence of liability of the other
     co-borrower or any defense to liability or enforcement which the other co-
     borrower may have and agrees that, by so doing, such Borrower's obligations
     hereunder shall continue even if the other Borrowers had no liability at
     the time of execution of this Agreement or thereafter ceased or cease to be
     liable.  Each Borrower also waives, to the extent permitted under
     Applicable Law, any and all benefits and defenses under any statute,
     regulation, judicial decision or other law which purports to limit the
     liability of a co-borrower to that of the other co-borrower or to reduce
     the liability of a co-borrower in proportion to any reduction in the
     liability of the other co-borrower and agrees that, by so doing, such
     Borrower's obligations hereunder may be more burdensome than that of the
     other Borrowers.

          (c) Each Borrower, to the extent permitted under Applicable Law,
     hereby waives any right, whether arising under any statute, regulation,
     judicial decision or otherwise, to require the Agent or any Lender to (i)
     proceed against the other Borrowers, (ii) proceed against or exhaust any
     security received from 

                                     -108-

 
     the other Borrowers, or (iii) pursue any other right or remedy in the
     Agent's or any Lender's power whatsoever.

          (d) Each Borrower further waives, to the extent permitted under
     Applicable Law:  (i) any defense resulting from the absence, impairment or
     loss of any right of reimbursement, subrogation, contribution or other
     right or remedy of such Borrower against the other Borrowers or any
     security, whether resulting from an election by the Agent or any Lender to
     foreclose upon security by judicial or nonjudicial sale or otherwise; (ii)
     any setoff or counterclaim of such Borrower or any defense of any kind
     (including defenses resulting from any disability) or the cessation or stay
     of enforcement from any cause whatsoever of the liability of such Borrower
     (including without limitation the lack of validity or enforceability of
     this Agreement or any other Loan Document); (iii) any right to exoneration,
     in whole or in part, of co-borrowers which would otherwise be applicable;
     (iv) any benefits and defenses under Applicable Law, including without
     limitation any right of subrogation or reimbursement, any right of
     contribution, any right to enforce any remedy which any Lender now has or
     may hereafter have against the other Borrowers, and any benefit of, and any
     right to participate in, any security now or hereafter held or received by
     any Lender; and (v) all valuation, appraisal, extension or redemption laws
     now or hereafter in effect.  Without limiting the generality of the
     preceding clause (iv), each Borrower hereby waives any right to be
     reimbursed by the other Borrowers for any payment of such obligations made
     directly or indirectly by such Borrower or from any property of such
     Borrower, whether arising by way of any statutory, contractual or other
     right of subrogation, contribution, indemnification or otherwise.

          (e) Each Borrower acknowledges that it has the ability, and hereby
     assumes the obligation and responsibility, to keep informed of the
     financial condition of the other Borrowers and of other matters or
     circumstances affecting the ability of the other Borrowers to pay or
     perform their obligations hereunder or the risk of nonpayment and
     nonperformance.  Each Borrower hereby waives, to extent permitted under
     Applicable Law, any obligation on the part of the Lenders to inform such
     Borrower of the financial condition, or any changes in financial condition,
     of the other Borrowers or of any other matter or circumstance which might
     affect the ability of the other Borrowers to pay and perform under this
     Agreement or any other Loan Document, or the risk of nonpayment or
     nonperformance.

     SECTION  11.16.  OTHER TRANSACTIONS.  Nothing contained herein shall
preclude the Agent or any other Lender or any of their respective Affiliates
from engaging in any transaction, in addition to those contemplated by this
Agreement or any other Loan Document, with the Borrower or any of its Affiliates
in which the Borrower or such Affiliate is not restricted hereby from engaging
with any other Person.

                                     -109-

 
       SECTION  11.17.  CONTROLLING DOCUMENT.  In the event of actual conflict
in the terms and provisions of this Agreement, the Notes and the other Loan
Documents, the terms and provisions of this Agreement will control.

     SECTION  11.18.  NOTICE.  THIS WRITTEN AGREEMENT TOGETHER WITH THE OTHER
LOAN DOCUMENTS REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS
OF THE PARTIES.

THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

                                     -110-
