         excluding) the L/C Commitment Termination Date, and to honor drafts
         duly presented under the Letters of Credit in accordance with the terms
         thereof; and (ii) the Lenders severally agree to participate in Letters
         of Credit issued by the Agent for the account of the Company.

         (b)  The Agent is under no obligation to issue any Letter of Credit if:

<PAGE>
 
         $29,725,000, or the aggregate Taxable L/C Outstandings would exceed
         $61,500,000.

              (ii)  any order, judgment or decree of any Governmental
         Authority or arbitrator shall by its terms purport to enjoin or
         restrain the Agent from issuing such Letter of Credit, or any
         applicable law or any request or directive (whether or not having the
         force of law) from any Governmental Authority with jurisdiction over
         the Agent shall prohibit, or request that the Agent refrain from, the
         issuance of letters of credit generally or such Letter of Credit in
         particular;

              (iii) the Agent has received written notice from any Lender or
         the Company, on or prior to the Business Day prior to the requested
         date of issuance of such Letter of Credit, that one or more of the
         applicable conditions contained in Section 7 is not then satisfied;
                                            ---------

              (iv)  the expiry date of any requested Letter of Credit is after
         the L/C Commitment Termination Date ;

              (v)   any requested Letter of Credit is not substantially in the
         form of Exhibit A-1 or Exhibit A-2, as applicable, or otherwise in form
         and substance acceptable to the Agent; or

              (vi)  any requested Letter of Credit is for the purpose of
         supporting any obligation other than the Issuer's obligations under the
         Bonds.

         SECTION 2.2     Issuance and Extension of Letters of Credit.
                         -------------------------------------------

         (a)  Each Letter of Credit shall be issued upon the irrevocable written
request of the Company received by the Agent at least one Business Day (or such
shorter time as the Agent may agree in a particular instance in its sole
discretion) prior to the proposed date of issuance. Each such request for
issuance of a Letter of Credit shall be by facsimile, confirmed promptly in an
original writing, in the form of an Application, and shall specify in form and
detail satisfactory to the Agent: (i) the face amount of the requested Letter of
Credit; (ii) the expiry date of such Letter of Credit; (iii) the name and
address of the beneficiary thereof; (iv) the documents to be presented by the
beneficiary of such Letter of Credit in case of any drawing thereunder; (v) the
full text of any certificate to be presented by the beneficiary in case of any
drawing thereunder; and (vi) such other matters as the Agent may require;
provided that the Credit Agreement shall prevail to the extent of any
--------
inconsistency between the Credit Agreement and any Application.

         (b)  Unless the Agent has actual knowledge that, or has received notice
prior to issuing a requested Letter of Credit from any Lender that one or more
conditions specified in Section 7 are not then satisfied, then, subject to the
                        --------- 
terms and conditions hereof, the 

                                       3
<PAGE>
 
Agent, on the requested date, shall issue a Letter of Credit for the account of
the Company in accordance with the Agent's usual and customary business
practices therefor.

         (c) The Agent and the Lenders agree that, upon extension of the L/C
Commitment Termination Date in accordance with Section 2.11, the Agent shall
                                               ------------
extend the expiry date of any Letter of Credit issued by it for a period equal
to the shorter of (i) one year from the then current expiry date and (ii) the
period ending on the L/C Commitment Termination Date (after giving effect to
such extension). Notwithstanding the foregoing, in no event shall any Letter of
Credit be renewed such that its revised expiry date would extend beyond the
Stated Maturity Date.

         (d) The Agent may, at its election (or shall at the direction of the
Required Lenders), deliver any notices of termination or other communications to
any Letter of Credit beneficiary or transferee, and take any other action as
necessary or appropriate, at any time and from time to time, in order to cause
the expiry date of such Letter of Credit to be a date not later than the L/C
Commitment Termination Date.

         SECTION 2.3     Risk Participations, Drawings and Reimbursements.
                         ------------------------------------------------

         (a) Immediately upon the issuance of each Letter of Credit, each Lender
(other than the Agent) shall be deemed to, and hereby irrevocably and
unconditionally agrees to, purchase from the Agent a participation in such
Letter of Credit and each drawing thereunder in an amount equal to the product
of (i) the Percentage of such Lender, times (ii) the maximum amount available to
be drawn under such Letter of Credit and the amount of such drawing,
respectively.

         (b) In the event of any request for a drawing under a Letter of Credit
by the beneficiary or transferee thereof, the Agent will promptly notify the
Company. The Company shall reimburse the Agent prior to 10:00 a.m. (Chicago
time) on each date that any amount is paid by the Agent under any Letter of
Credit (each such date, an "Honor Date"), in an amount equal to the amount so
                            ----------
paid by the Agent. In the event the Company fails to reimburse the Agent for the
full amount of any drawing under any Letter of Credit by 10:00 a.m. (Chicago
time) on the Honor Date, the Agent will promptly notify each Lender thereof,
which notice shall be conclusive and binding on the Lenders. Any notice given by
the Agent pursuant to this Section 2.3(b) may be oral if immediately confirmed
                           --------------
in writing (including by facsimile); provided, that the lack of such an
                                     --------
immediate confirmation shall not affect the conclusiveness or binding effect of
such notice.

         (c) Each Lender (other than the Agent) shall upon any notice pursuant
to Section 2.3(b) make available to the Agent for its account an amount in
   --------------
Dollars and in immediately available funds equal to its Percentage of the amount
of the drawing. If any Lender so notified on or before 11:00 a.m. (Chicago time)
fails to make available to the Agent for its account the amount of such Lender's
Percentage of the amount of the drawing by no later 

                                       4
<PAGE>
 
than 1:00 p.m. (Chicago time) on the Honor Date (or if so notified after 11:00
a.m. (Chicago time) on or before 10:00 a.m. (Chicago time) on the next following
Business Day), then interest shall accrue on such Lender's obligation to make
such payment, from the Honor Date to the date such Lender makes such payment, at
a rate per annum equal to the Federal Funds Rate in effect from time to time
during such period. The Agent will promptly give notice of the occurrence of the
Honor Date, but failure of the Agent to give any such notice on the Honor Date
or in sufficient time to enable any Lender to effect such payment on such date
shall not relieve such Lender from its obligation to provide such Lender's
Percentage amount of such drawing under this Section 2.3.
                                             -----------

         (d) With respect to any drawing not reimbursed under Section 2.3(b) and
not constituting an L/C Loan under Section 2.7, the Reimbursement Obligation
(together with interest) shall be due and payable on demand and shall bear
interest at a rate per annum equal to the Past-Due Rate, and each Lender's
payment to the Agent pursuant to Section 2.3(c) shall be deemed payment in
                                 -------------
respect of its participation in such Reimbursement Obligation in satisfaction of
its participation obligation under this Section 2.3.
                                        -----------

         (e) Each Lender's obligation in accordance with this Agreement to make
the funds available to the Agent, as contemplated by this Section 2.3, as a
                                                          -----------
result of a drawing under a Letter of Credit, shall be absolute and
unconditional and without recourse to the Agent and shall not be affected by any
circumstance, including (i) any set-off, counterclaim, recoupment, defense or
other right which such Lender may have against the Agent, the Company or any
other Person for any reason whatsoever; (ii) the occurrence or continuance of a
Default, an Unmatured Default or an event which could reasonably be expected to
have a Material Adverse Effect; or (iii) any other circumstance, happening or
event whatsoever, whether or not similar to any of the foregoing.

         SECTION 2.4     Role of the Agent as Issuer.
                         ---------------------------

         (a) Each Lender and the Company agree that, in paying any drawing under
a Letter of Credit, the Agent 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.

         (b) The Agent shall, promptly following its receipt thereof, examine
all documents purporting to represent a demand for payment by the Trustee under
any Letter of Credit to ascertain that the same appear on their face to be in
conformity with the terms of and covered by such Letter of Credit. If, after
examination, the Agent shall have determined that a demand for payment under
such Letter of Credit does not conform to the terms and conditions of such
Letter of Credit, then the Agent shall, as soon as reasonably practicable, give
notice to the Trustee to the effect that negotiation was not in accordance with
the terms and conditions of the Letter of Credit, stating the reasons therefor
and that 

                                       5
<PAGE>
 
the relevant documents are being held at the disposal of the Trustee or are
being returned to the Trustee, as the Agent may elect. The Trustee may attempt
to correct any such nonconforming demand for payment under such Letter of Credit
if, and to the extent that, the Trustee is entitled (without regard to the
provisions of this sentence) and able to do so. If the Agent determines that a
demand for payment under such Letter of Credit conforms to the terms and
conditions of such Letter of Credit, then the Agent shall make payment to the
Trustee in accordance with the terms of such Letter of Credit. The Agent shall
have the right, provided it is not then in default under such Letter of Credit
by reason of its having wrongfully failed to honor a demand for payment
previously made by the Trustee under such Letter of Credit, to require the
Trustee to surrender such Letter of Credit to the Agent on the L/C Commitment
Termination Date after honoring any draws rightfully made by the Trustee under
such Letter of Credit on that date. The Company agrees, if necessary, to use its
best efforts to cause the Trustee so to surrender such Letter of Credit.

         (c) No Agent-Related Person nor any of the respective correspondents,
participants or assignees of the Agent shall be liable to any Lender for: (i)
any action taken or omitted in connection herewith at the request or with the
approval of all of the Lenders or the Required Lenders, as applicable; (ii) any
action taken or omitted in the absence of gross negligence or willful
misconduct; or (iii) the due execution, effectiveness, validity or
enforceability of any L/C-Related Document.

         (d) The Company hereby assumes all risks of the acts or omissions of
any beneficiary or transferee with respect to its use of any Letter of Credit;
provided, that such assumption is not intended to, and shall not, preclude the
--------
Company's pursuing such rights and remedies as it may have against the
beneficiary or transferee at law or under any other agreement. No Agent-Related
Person, nor any of the respective correspondents, participants or assignees of
the Agent, shall be liable or responsible for any of the matters described in
clauses (i) through (vii) of Section 2.5; provided, anything in such clauses to
----------           ---     -----------  -------- 
the contrary notwithstanding, that the Company may have a claim against the
Agent, and the Agent may be liable to the Company, to the extent, but only to
the extent, of any direct, as opposed to consequential or exemplary, damages
suffered by the Company which the Company proves were caused by the Agent's
willful misconduct or gross negligence or the Agent's willful failure to pay
under any Letter of Credit after the presentation to it by the beneficiary of a
sight draft and certificate(s) strictly complying with the terms and conditions
of a Letter of Credit. In furtherance and not in limitation of the foregoing:
(i) the Agent may accept documents that appear on their face to be in order,
without responsibility for further investigation, regardless of any notice or
information to the contrary; and (ii) the Agent shall not be responsible for the
validity or sufficiency 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.

         SECTION 2.5     Obligations Absolute. The obligations of the Company
                         --------------------

drawing under a Letter of Credit, and to repay any Reimbursement Obligation and

unconditional and irrevocable, and shall be paid strictly in accordance with the
terms of this Agreement and each such other L/C-Related Document under all
circumstances, including the following:

         any other term of, all or any of the obligations of the Company in
         respect of any Letter of Credit or any other amendment or waiver of or
         any consent to departure from all or any of the L/C-Related Documents;

              (iii) the existence of any claim, set-off, defense or other right
         that the Company 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 Agent or any
         other Person, whether in connection with this Agreement, the
         transactions contemplated hereby or by the L/C-Related Documents or any
         unrelated transaction;

              (iv)  any draft, demand, certificate or other document presented
         under any Letter of Credit proving to be forged, fraudulent, invalid or
         insufficient in any respect or any statement therein being untrue or
         inaccurate in any respect; or any loss or delay in the transmission or
         otherwise of any document required in order to make a drawing under any
         Letter of Credit;

              (v)   any payment by the Agent 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
         Agent 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,
         unless such payment in on the part of the Agent;

              (vi)  any exchange, release or non-perfection of any
         collateral, or any release or amendment or waiver of or consent to
         departure from any other guarantee, for all or any of the obligations
         of the Company in respect of any Letter of Credit; or

                                       7
<PAGE>
 
              (vii) 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 Company or a guarantor.

         SECTION 2.6     Uniform Customs and Practice. Except as otherwise
                         ----------------------------
expressly provided therein 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 apply to such Letter of
Credit.

         SECTION 2.7     L/C Loans. If the Agent shall make any payment under
                         ---------
any Letter of Credit pursuant to a Tender Draft and the conditions precedent in
Section 7.3 shall have been fulfilled, such payment shall constitute an advance
-----------
made by the Lenders to the Company on the date and in the amount of such
payment, each such advance being an "L/C Loan". The Company shall repay the
                                     --------
unpaid principal amount of each L/C Loan on or before the earlier of (i) the
Stated Maturity Date or (ii) on the same date on which the Bonds, with respect
to which payment against such Tender Draft was made, are sold as a result of a
remarketing (which payment shall be made in accordance with Section 2.10(b) with
                                                            ---------------
any deficiency in the amount due paid by the Company).

         SECTION 2.8     Interest Provisions.
                         -------------------

         (a)   Interest Rates. The Company will pay interest on the unpaid
               --------------

of such L/C Loan to (but excluding) the date such L/C Loan shall be paid in
full, at the following rates per annum:

               (i)   during each period such L/C Loan is an ABR Loan, the ABR
         Rate from time to time in effect; and

               (ii)  during each Interest Period such L/C Loan is a LIBOR Loan,
         the LIBOR Rate for such Interest Period plus the Applicable Margin.
                                                 ----

Each LIBOR Loan shall bear interest from (and including) the first day of the
applicable Interest Period to (but excluding) the last day of such Interest
Period at the interest rate determined as applicable to such LIBOR Loan.
Promptly after the determination of any interest rate provided for in this
Section 2.8(a) or any change therein, the Agent shall give notice thereof to the
--------------
Lenders to which such interest is payable and to the Company.

         (b)   Other Interest Provisions. Notwithstanding the foregoing
               -------------------------
provisions of this Section 2.8, (i) the Company hereby promises to pay to the
                   -----------
Agent for the account of each Lender interest at the applicable Past-Due Rate on

                                       8
<PAGE>
 
not be paid in full when due (whether at stated maturity, by acceleration, by
mandatory prepayment or otherwise), for the period from (and including) the due
date thereof to (but excluding) the date the same is paid in full and (ii) in
addition (without duplication), during any period in which a Default shall have
occurred and be continuing, the Company hereby promises to pay to the Agent for
the account of each Lender interest on any principal of any L/C Loan made by
such Lender and on any other amount payable by the Company hereunder at a rate
per annum equal to 2% above the rates (including any Applicable Margin)
otherwise applicable hereunder to such principal and such other amount,
respectively. Accrued interest on each L/C Loan shall be payable (i) in the case
of an ABR Loan, quarterly on the last day of each March, June, September and
December, (ii) in the case of a LIBOR Loan, on the last day of each Interest

               ------------
notwithstanding, in the event that the interest rate chargeable on any of the
L/C Loans or Reimbursement Obligations pursuant to the terms of this Agreement
shall exceed the highest lawful rate that may be charged under applicable law,
the interest rate shall be deemed to be equal to the highest lawful rate.

         SECTION 2.9     Conversions or Continuations of L/C Loans. Subject to
                         -----------------------------------------
Sections 4.5 and 5.5, the Company shall have the right to Convert L/C Loans of
------------     ---
one Type into L/C Loans of the other Type or to Continue LIBOR Loans, at any
time or from time to time; provided, that the Company shall give the Agent
                           --------
notice of each such Conversion or Continuation as provided in Section 4.6.
                                                              -----------
Notwithstanding the foregoing, and without limiting the rights and remedies of
any of the Lenders and the Agent under Section 10, in the event that any Default
                                       ----------
or Unmatured Default shall have occurred and be continuing, the Agent may (and
at the request of the Required Lenders shall) suspend the right of the Company

of such prepayment 

                                       9
<PAGE>
 
on the amount prepaid; provided, that no notice shall be required and no
                       --------
interest shall accrue with respect to any such borrowing which is prepaid by the
Company on the date on which such amount is drawn under any Letter of Credit;
and provided, further, that the Company shall not be entitled to prepay any
    --------  -------
LIBOR Loan (other than on the last day of the applicable Interest Period) unless
such prepayment (including, without limitation, any such payment made in
accordance with Section 2.10(b)) shall be accompanied by an additional payment,
                ---------------
in accordance with Section 5.3, of an amount sufficient to compensate the
                   -----------
Lenders for any loss (including loss of anticipated profits), cost or expense
incurred by it by reason of such prepayment. L/C Loans prepaid after the L/C
Commitment Termination Date may not be reborrowed.

         (b)  Mandatory Repayments.

               (i)  Simultaneously with the resale of Bonds acquired by the
         Trustee with the proceeds of one or more drawings pursuant to a Tender

         paying to the Agent for the account of the Lenders an amount equal to
         the sum of (x) the aggregate principal amount of the Bonds resold plus
         (y) the aggregate amount of accrued and unpaid interest on the L/C
         Loans and Reimbursement Obligations incurred with respect to such
         Bonds. Such payments when accompanied by a certificate completed and
         signed by the Trustee in substantially the form of Exhibit A, B or C,

any W/C Loan to be made by it on the date specified therefor shall not relieve
such Lender or any other Lender of its obligation to make its W/C Loan on such
date, but neither any Lender nor the Agent shall be responsible for the failure
of any other Lender to make a W/C Loan to be made by such other Lender.

         SECTION 3.5     Repayment of Loans. The Company hereby promises to pay
                         ------------------

Each LIBOR Loan shall bear interest from (and including) the first day of the
applicable Interest Period to (but excluding) the last day of such Interest
Period at the interest rate determined as applicable to such LIBOR Loan.
Promptly after the determination of any interest rate provided for in this
Section 3.6(a) or any change therein, the Agent shall give notice thereof to the

otherwise), for the period from (and including) the due date thereof to (but
excluding) the date the same is paid in full and (ii) in addition (without
duplication), during any period in which a Default shall have occurred and be
continuing, the Company hereby promises to pay to the Agent for the account of
each Lender interest on any principal of any W/C Loan made by such Lender and on
any other amount payable by the Company

Applicable Margin) otherwise applicable hereunder to such principal and such
other amount, respectively. Accrued interest on each W/C Loan shall be payable
(i) in the case of an ABR Loan, quarterly on the last day of each March, June,
September and December, (ii) in the case of a LIBOR Loan, on the last day of
each Interest Period therefor and, if any such Interest Period is longer than
three months, at three-month intervals following the first day of such Interest
Period, (iii) in the case of any W/C Loan, upon the payment or prepayment
thereof (but only on the principal amount so paid or prepaid), and (iv) in the
case of any W/C Loan, upon the Conversion of such W/C Loan to a W/C Loan of the
other Type (but only on the principal amount so Converted), except that interest
                                                            ------

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

         (c)   Maximum Rate. Anything in this Agreement to the contrary
               -------------
notwithstanding, in the event that the interest rate chargeable on any of the
W/C Loans pursuant to the terms of this Agreement shall exceed the highest
lawful rate that may be charged under applicable law, the interest rate shall be
deemed to be equal to the highest lawful rate.

         SECTION 3.7     Conversions or Continuations of W/C Loans. Subject to
                         -----------------------------------------
Sections 4.5 and 5.3, the Company shall have the right to Convert W/C Loans of
------------     ---
one Type into W/C Loans of the other Type or to Continue LIBOR Loans, at any

notice of each such Conversion or Continuation as provided in Section 4.6.
                                                              -----------
Notwithstanding the foregoing, and without limiting the rights and remedies of
any of the Lenders and the Agent under Section 10, in the event that any Default
                                       ----------
or Unmatured Default shall have occurred and be continuing, the Agent may (and

taken by the Agent, the records of the Agent shall govern absent manifest error.

         SECTION 4.7     Booking Offices. Each Lender may book its Loans at any
                         ---------------
Booking Office selected by such Lender and may change its Booking Office from
time to time. All terms of this Agreement shall apply to any such Booking
Office. Subject to Section 5.5, each Lender may, by written or telex notice to
                   -----------
the Agent and the Company, designate a Booking Office through which Loans will
be made by it and for whose account payments are to be made on its Loans.

         SECTION 4.8     Non-Receipt of Funds by the Agent. Unless the Company
                         ---------------------------------
or a Lender, as the case may be, notifies the Agent prior to the date on which
it is scheduled to make payment to the Agent of (a) in the case of a Lender, the
participation in a Letter of Credit or proceeds of a Loan, or (b) in the case of
the Company, a payment of principal, interest or fees to the Agent for the
account of the Lenders, that it does not intend to make such payment, the Agent
may assume that such payment has been made. The Agent may,

                                       18
<PAGE>
 
but shall not be obligated to, make the amount of such payment available to the
intended recipient in reliance upon such assumption. If such Lender or the
Company, as the case may be, has not in fact made such payment to the Agent, the
recipient of such payment shall, on demand by the Agent, repay to the Agent the
amount so made available together with interest thereon in respect of each day
during the period commencing on the date such amount was so made available by
the Agent until the date the Agent recovers such amount at a rate per annum
equal to (i) in the case of payment by a Lender, the Federal Funds Rate for such
day or (ii) in the case of payment by the Company, the interest rate applicable
to the relevant Loan or Reimbursement Obligation.

         SECTION 4.9     Setoff. In addition to, and without limitation of, any
                         ------
rights of the Lenders under applicable law, if the Company becomes insolvent,
however evidenced, or a Default occurs, any indebtedness from any Lender to the
Company (including all account balances, whether provisional or final and
whether or not collected or available) may, subject to Section 4.10, be offset
                                                       ------------
and applied toward the payment of the Secured Obligations owing to such Lender,
whether or not the Secured Obligations, or any part of them, shall then be due.

         SECTION 4.10    Ratable Payments. If any Lender, whether by setoff or
                         ----------------
otherwise, has payment made to it upon its Loans or Reimbursement Obligations
(other than payments received pursuant to Sections 5.1, or 5.3) in a greater
                                          ------------     ---
proportion than that received by any other Lender, such Lender agrees, promptly
upon demand, to purchase a portion of the Loans or Reimbursement Obligations
held by the other Lenders so that after such purchase each Lender will hold its
ratable proportion of Loans or Reimbursement Obligations. If any Lender, whether
in connection with setoff or amounts which might be subject to setoff or
otherwise, receives Collateral or other protection for its Secured Obligations
or such amounts which may be subject to setoff, such Lender agrees, promptly
upon demand, to take such action as may be necessary such that all Lenders share
in the benefits of such Collateral ratably in proportion to their Loans or
Reimbursement Obligations. In case any such payment is disturbed by legal
process, or otherwise, appropriate further adjustments shall be made.

                   YIELD PROTECTION; CHANGE IN CIRCUMSTANCES

         SECTION 5.1     Yield Protection. If any law or any Governmental or
                         ----------------
quasi-Governmental Rule (whether or not having the force of law), or any
interpretation thereof, or the compliance of any Lender therewith,

               (i)  subjects any Lender or any applicable Booking Office to any
         tax, duty, charge or withholding on or from payments due from the
         Company (excluding federal taxation of the overall net income of any
         Lender or applicable Booking 

                                       19

         Office), or changes the basis of taxation of payments to any Lender in
         respect of its Loans or other amounts due it hereunder, or

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

                  (iii) imposes any other condition the result of which is to
         increase the cost to any Lender or any applicable Booking Office of
         making, funding or maintaining loans or reduces any amount receivable
         by any Lender or any applicable Booking Office in connection with loans
         or letters of credit, or requires any Lender or any applicable Booking
         Office to make any payment calculated by reference to the amount of
         loans held, letters of credit issued or interest received by it, by an
         amount deemed material by such Lender,

then, within 15 days of demand by such Lender, the Company shall pay such Lender
----
that portion of such increased expense incurred or reduction in an amount
received which such Lender determines is attributable to making, funding and
maintaining its Loans, provided, however, that the Company shall not be required
to pay such costs with respect to any such change in circumstances occurring
more than ninety days preceding the foregoing demand from such Lender.

         SECTION 5.2     Changes in Capital Adequacy Regulations. If a Lender
                         ---------------------------------------
determines the amount of capital required or expected to be maintained by such
Lender, any Booking Office of such Lender or any corporation controlling such
Lender is increased as a result of a Change, then, within 15 days of demand by
                                             ----
such Lender, the Company shall pay such Lender the amount necessary to
compensate for any shortfall in the rate of return on the portion of such
increased capital which such Lender determines is attributable to the Credit
Agreement, its Loans, any Letters of Credit issued or participated in by it or
its obligation hereunder to make any Loans or issue or make advances pursuant to
any Letter of Credit (after taking into account such Lender's policies as to
capital adequacy), provided, however, that the Company shall not be required to
                   --------
pay such costs with respect to any such Change occurring more than ninety days
preceding the foregoing demand from such Lender. "Change" means (i) any change
                                                  ------
after the Closing Date in the Risk-Based Capital Guidelines or (ii) any adoption
of or change in any other law, Governmental of quasi-Governmental Rule (whether
or not having the force of law), after the Closing Date which affects the amount
of capital required or expected to be maintained by any Lender or any Booking
Office or any corporation controlling any Lender. "Risk-Based Capital
                                                   ------------------
Guidelines" means (a) the risk- based capital guidelines in effect in the United
----------
States on the Closing Date, including transition rules, and (b) the
corresponding capital regulations promulgated by regulatory authorities outside
the United States

Measurements and Capital Standards," including transition rules, and any
amendments to such regulations adopted prior to the date of the Credit
Agreement.

         SECTION 5.3     Availability of Types of Loans. If any Lender
                         ------------------------------
determines that maintenance of its LIBOR Loans at a suitable Booking Office
would violate any applicable Governmental Rule, whether or not having the force
of law, or if the Required Lenders determine that (a) deposits of a type and
maturity appropriate to match fund LIBOR Loans are not available or (b) the
interest rate applicable to a LIBOR Loan does not accurately reflect the cost of
making or maintaining such Loan, then the Agent shall suspend the availability
of LIBOR Loans and require any outstanding LIBOR Loans, at the option of the
Company, to be repaid or converted into ABR Loans, in each case subject to
Section 5.4.
-----------

         SECTION 5.4     Funding Indemnification. If any payment of a LIBOR Loan
                         -----------------------
occurs on a date which is not the last day of the applicable Interest Period,
whether because of acceleration, prepayment or otherwise, or if any Loan is not
made or Converted or Continued on the date specified by the Company for any
reason other than default by the Lenders, then the Company will indemnify each
Lender for any loss or cost incurred by it resulting therefrom, including,
without limitation, any loss or cost in liquidating or employing deposits
acquired to fund or maintain such Loan.

         SECTION 5.5     Taxes.
                         -----

         (a) All payments made by the Company under this Agreement to the Agent,
and the Lenders shall be made free and clear of, and without reduction or
withholding for or on account of, any future income, franchise, property,
excise, sales, stamp or other taxes, levies, imposts, duties, charges, fees,
deductions or withholdings, hereafter imposed, levied, collected, withheld or
assessed by any Governmental Authority of the United States or any political
subdivision thereof, excluding, in the case of the Agent, and each Lender, net
income and franchise taxes imposed on the Agent or such Lender, as the case may
be, by the jurisdiction under the laws of which the Agent or such Lender, as the
case may be, is organized or any political subdivision or taxing authority
thereof or therein, or by any jurisdiction in which the Agent or such Lender or
its Booking Office, as the case may be, is located or any political subdivision
or taxing authority thereof or therein (all such non-excluded taxes, levies,
imposts, deductions, charges or withholdings being hereinafter called "Taxes").
If any Taxes are required to be withheld from any amounts payable to the Agent
or any Lender hereunder the amounts so payable to the Agent or such Lender, as
the case may be, shall be increased to the extent necessary to yield (after
payment of all Taxes) to the Agent or such Lender, as the case may be, interest
or any such other amounts payable hereunder at the rates or in the amounts
specified in this Agreement. Each Lender will designate a different Booking
Office if such designation would avoid the need for, or, if unavoidable, reduce
the amount of, such increase and would not, in the sole 

                                       21
<PAGE>
 
opinion of such Lender, be disadvantageous to such Lender. Whenever any Taxes
are payable by the Company, as promptly as possible thereafter, the Company
shall send to the Agent for its own account or for the account of such Lender, a
certified copy of any original official receipt received by the Company showing
payment thereof. The Company shall indemnify the Agent, and the Lenders for any
incremental taxes, interest or penalizes that may become payable by the Agent or
any such Lender as a result of any failure by the Company to pay any Taxes when
due to the appropriate taxing authority or to remit to the Agent the required
receipts or other required documentary evidence.

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

         SECTION 5.6     Lender Statements; Survival of Indemnity. To the extent
                         ----------------------------------------
reasonably possible, each Lender shall designate an alternate Booking Office
with respect to its LIBOR Loans to reduce any liability of the Company to such
Lender under Sections 5.1 and 5.3 or to avoid the unavailability of LIBOR Loans
             ------------     ---
under Section 5.3, so long as such designation is not disadvantageous to such
      -----------
Lender in its sole determination. Each Lender shall deliver a written statement
of such Lender to the Company (with a copy to the Agent) as to the amount due,
if any, under Section 5.1, 5.2, 5.4 or 5.5. Such written statement shall set
              -----------  ---  ---    ---
forth in reasonable detail the calculations upon which such Lender determined
such amount and shall be final, conclusive and binding on the Company in the
absence of manifest error. Determination of amounts payable under such Sections
in connection with a LIBOR Loan shall be calculated as though each Lender funded
its LIBOR Loan through the purchase of a deposit of the type and maturity
corresponding to the deposit used as a reference in determining the LIBOR Rate
applicable to such LIBOR 

                                       22
<PAGE>
 
Loan, whether in fact that is the case or not. Unless otherwise provided herein,
the amount specified in the written statement of any Lender shall be payable
within 15 days of receipt by the Company of such written statement. The
obligations of the Company under Sections 5.1, 5.2, 5.4 and 5.5 shall survive
                                 ------------  ---  ---     ---
payment or prepayment of the Credit Obligations and the termination of the
Credit Agreement.

Corporation (each a "Pledgor" and collectively the "Pledgors") and the Agent
have entered into a Pledge Agreement dated as of November 23, 1998, pursuant to
which the Pledgors have granted to the Agent, for the benefit of the Lenders, a
security interest and assignment in certain assets, including without
limitation, the Pledgors' membership interest in the Company and all proceeds
and products thereof (collectively, the "Collateral"). The Pledgors hereby
request the Company to enter into this Control Agreement. The Company hereby
agrees as follows:

          1.   The Company agrees that it will comply with instructions from the
     Agent with respect to the Collateral without further consent by the
     Pledgors. Such instructions may include, without limitation, a direction to

     membership interests of the Pledgors on its books and records.

          3.   The Pledgors may not amend or terminate this Control Agreement
     without the Agent's prior written consent.

          4.   This Control Agreement is governed by the internal laws (and not

          5.   The Company covenants that it will not accept any notice of lien,
     encumbrance, pledge with respect to the Collateral, will not accept any
     notice of transfer unless such transfer does not result in a Company Change
     of Control (as defined in the Credit Agreement) and will not enter into any
     agreement to comply with instructions from any other party with respect to
     the Collateral, except for any such agreement with the Agent, until the
     Agent sends a notice to the Company that this Control Agreement has been
     terminated.

          6.   The Company hereby represents and warrants that as of the date
     hereof:

               (a)  each Pledgor is the registered owner of its respective
          Collateral on the books and records of the membership, and the Company
          has no knowledge of any lien, encumbrance, pledge or transfer of the
          Collateral, has not registered any security interest in the Collateral
          and has not entered into any agreement with any other party to comply
          with instructions from such party with respect to the Collateral;

               (b)  none of the Collateral is evidenced by a certificate; and

          issuance or transfer of the Collateral.

                    --------                                                    
be required to, make demand for payment under any letters of credit assigned to

19.  If, solely as a result of a transfer or withdrawal of funds as permitted in
this Section 15, the Company is unable to fulfill its obligations under the

to the extent funds remain in the Collateral Account, redeposit such funds in
the Accounts from which such funds were transferred.   In the event that there
are insufficient funds in the Collateral Account to redeposit such funds in the
Accounts from which such funds were transferred, the Agent shall deposit such
funds into the Operating Account for application pursuant to Section 9.28 of the
Credit Agreement; provided, however, that if a deposit into the Debt Service
                  --------  -------                                         
Reserve Account or the Sinking Fund Accounts is required to be made pursuant to
the Credit Agreement on the date of such deposit, the Agent shall transfer to
each such Account or Accounts (in the order of priority set forth in Section
9.28 of the Credit

so that the amount on deposit therein is equal to the amount required to be on

     SECTION 16.  Agent and Appointed Attorney-in-Fact.  The Company hereby
                  ------------------------------------                     
irrevocably appoints the Agent as the Company's attorney-in-fact (which
appointment as attorney-in-fact is coupled with an interest), with full
authority in the place and stead of the Company and in the name of the Company,
effective upon the occurrence of a Default and from time to time thereafter in
the Agent's discretion to take any action and to execute any instrument which
the Agent may reasonably deem necessary or advisable to accomplish the purposes
of this Agreement, including to ask, demand, collect, sue for, recover and
receive moneys due and to become due under or in connection with the Collateral,
to receive, indorse and collect any drafts or other instruments, documents and
chattel paper in connection therewith and to file any claims or take any action
or institute any proceedings which the Agent, may reasonably deem necessary or
desirable for the collection thereof or to enforce compliance with the terms and
conditions of the Assigned Agreements or this Agreement.  Notwithstanding the
foregoing, the Agent shall not be obligated to exercise any right or duty as
attorney-in-fact, and shall not have any duty to the Company in connection
therewith.

     SECTION 17.  Agent May Perform.  Subject to provisions of any applicable
                  -----------------                                          
Consent and Agreement, following a Default the Agent may, but shall not be
required to, perform, or cause performance of, any agreement contained herein or
in any of the Assigned Agreements and the expenses of the Agent incurred in
connection therewith shall be payable by the Company pursuant to Section 20(b).
                                                                 -------------  
Subject to the provisions of any applicable Consent and Agreement, if any
default by the Company under any Assigned Agreement shall occur, the Agent
shall, at its option, be permitted (but shall not be obligated) to remedy any
such default by giving written notice of such intent to the Company and to the
parties to such Assigned Agreement in default.  The Agent shall have a
reasonable opportunity to cure such default.  Any cure by the Agent of the
Company's default under any Assigned Agreement shall not be construed as an
assumption by the Agent of any obligations, covenants or agreements of the
Company under such Assigned Agreement, and the Agent shall not incur any
liability to the Company or any other Person as a result of any actions
undertaken by the Agent or in curing or attempting to cure any such default.
This Agreement shall not be deemed to release or to affect in any way the
obligations of the Company under the Assigned Agreements.

                  ------------------                                    
hereunder shall not impose any duty upon it to exercise any such powers.  Except
for the safe custody of any Collateral in its possession and the accounting for
moneys actually received by it hereunder, the Agent shall have no duty as to any
Collateral or as to the taking of any necessary steps to preserve any rights
pertaining to any Collateral.

     SECTION 19.  Rights and Remedies.  (a)  All payments received by the
                  -------------------                                    
Company under or in connection with the Assigned Agreements or otherwise in
respect of the Collateral shall be

received in trust to the extent of the Secured Obligations for the benefit of
the Secured Parties, and shall be deposited in the same form as so received
(with any necessary endorsement) in the Accounts as provided in this Agreement.

     (b)  If a Default shall have occurred, all payments made under or in
connection with the Assigned Agreements or in respect of the other Collateral
and held by the Agent in the Collateral Account in accordance with the
provisions of this Agreement may, subject to the provisions of this Agreement,
at any time thereafter be applied as follows:

          First, to the payment of (A) all costs and expenses relating to the
          -----                                                              
     sale or other disposition of the Collateral or any part thereof and
     collection of amounts owing hereunder, including reasonable attorneys' fees
     and disbursements and the just compensation of the Agent for services
     rendered in connection therewith or in connection with any proceeding to
     sell if a sale is not completed, and (B) all reasonable charges, expenses
     and advances incurred or made by the Agent in order to protect the lien and
     security interest of this Agreement or the security afforded hereby,
     together with interest accrued thereon at a rate per annum equal to the sum
     of the ABR Rate plus 2%;

          Second, to the payment of accrued interest on the Loans in such manner
          ------                                                                
     as the Agent shall direct so that each of the Lenders shall have an
     equivalent number of days with respect to which interest on the Loans shall
     have accrued and be unpaid;

          Third, to the payment in full of accrued interest on the Loans (to be
          -----                                                                
     paid to the Lenders pro rata in accordance with the respective unpaid
     amounts of interest owed to them);

          Fourth, to cash collateralize the Letters of Credit;
          ------                                              

          Fifth, pro rata to the payment of:
          -----                             

               (i)  unpaid principal of the Loans then due and owing,

               (ii) the Termination Amount then due and owing with respect to
          the aggregate amount payable as a result of termination of the Hedge

          (payments under clause (i) to be made pro rata among the Lenders in
          accordance with the amounts of principal owed to them, and payments
          under clause (ii) to be made pro rata among the Hedge Counterparties);

          For purposes of this paragraph Fifth, "Termination Amount" shall mean
                                                 ------------------            
          an amount equal to the aggregate amount payable as a result of
          termination of Hedge Agreements in connection with the Loans being
          repaid under this paragraph Fifth or the cash collateralization of the
          Letters of Credit under paragraph Fourth;

                                     -13-
<PAGE>
 
          Sixth, to the payment of all other Secured Obligations then due and
          -----                                                              
     owing to the Secured Parties (to be paid to the Secured Parties pro rata in
     accordance with the respective aggregate outstanding amounts of such other
     Secured Obligations owed to them); and
 
          Seventh, provided all Secured Obligations owed (whether or not then
          -------                                                            
     due) to the Secured Parties have been paid in full, the balance, if any,
     shall be paid to such other Person as shall be lawfully entitled to receive
     any thereof, and finally, to the Company.

     (c)  If a Default shall have occurred, then, in addition to any other
rights and remedies provided for herein or which may otherwise be available, the
Agent shall, upon the direction of the Required Lenders, without any further
demand, advertisement or notice (except as expressly provided for below in this
                                 ------
Section 19(c) or as required by applicable law), exercise all the rights and
-------------                                         
remedies of a secured party under the UCC (whether or not the UCC applies to the
affected Collateral), and in addition may sell or otherwise dispose of the
Collateral, or any part thereof, as hereinafter provided. In connection
therewith, the Collateral may be sold in one or more sales, at public or private
sale, conducted by any officer or agent of, or auctioneer or attorney for, the
Agent, at the Agent's place of business or elsewhere, for cash, upon credit or
for other property, for immediate or future delivery, on such terms as the Agent
shall deem appropriate and at such price or prices as the Agent shall deem best.
The Agent and any other Secured Party may be the purchaser of any or all of the
Collateral so sold at a public sale, and the obligations of the Company to any
such purchaser may be applied as a credit against the purchase price. The Agent
may, in its sole discretion, at any such sale, restrict the prospective bidders
or purchasers as to the nature of their business, their experience and ability
with respect to the operation of medium density fiberboard plants similar to the
Facility and their ownership structure. Upon any such sale, the Agent shall have
the right to deliver, assign and transfer to the purchaser thereof the
Collateral so sold. Each purchaser (including the Agent and any other Secured
Party) at any such sale shall hold the Collateral so sold absolutely free from
any claim or right of the Company of whatsoever kind, including any equity or
right of redemption, and the Company hereby specifically waives, to the full
extent it may lawfully do so, all rights of redemption, stay or appraisal now
existing or hereafter adopted. The Agent shall give the Company at least 10
days' notice (which the Company agrees is reasonable notification within the
meaning of Section 9-504(3) of the UCC) of any such public or private sale. Such
notice, in case of public sale, shall state the time and place fixed for such
sale. Any such public sale shall be held at such time or times within ordinary
business hours as the Agent shall fix in the notice of such sale. At any such
sale, the Collateral may be sold in one lot as an entirety or in separate
parcels. The Agent shall not be obligated to make any sale pursuant to any such
notice. The Agent may, without notice or publication, adjourn any public or
private sale or cause the same to be adjourned from time to time by announcement
at the time and place fixed for such sale, and any such sale may be made at any
time or place to which the same may be so adjourned without further notice or
publication. In case of any sale of all or any part of the Collateral on credit
or for future delivery, the Collateral so sold may be retained by the Agent
until the full selling price is paid by the purchaser thereof, but the Agent
shall not incur any liability in case of the failure of such purchaser to take
up and

                                     -14-
<PAGE>
 
pay for the Collateral so sold, and, in case of any such failure, such
Collateral may again be sold pursuant to the provisions hereof.

     (d)  If a Default shall have occurred, instead of exercising the power of
sale provided in Section 19(c), the Agent shall, upon the direction of the
                 -------------                                            
Required Lenders, proceed by a suit or suits at law or in equity to foreclose
the pledge and security interest under this Agreement and sell the Collateral or
any portion thereof under a judgment or decree of a court or courts of competent
jurisdiction.

     (e)  If a Default shall have occurred, the Agent, as attorney-in-fact
pursuant to Section 16, may, in the name and stead of the Company, make and
            ----------                                                     
execute all conveyances, assignments and transfers of the Collateral sold
pursuant to Section 19(c), and the Company hereby ratifies and confirms all that
            -------------                                                       
the Agent, as said attorney-in-fact, shall do by virtue hereof. Nevertheless,
the Company shall, if so requested by the Agent, ratify and confirm any sale or
sales by executing and delivering to the Agent, or to such purchaser or
purchasers, all such instruments as may, in the judgment of the Agent, be
advisable for the purpose.

     (f)  The receipt of the Agent for the purchase money paid at any sale made
by it pursuant to Section 19(c) shall be a sufficient discharge to any purchaser
                  -------------                                                 
for the purchase price of the Collateral, or any portion thereof, sold as
aforesaid; and no such purchaser (or the representatives or assigns of such
purchaser), after paying such purchase money and receiving such receipt, shall
be bound to see to the application of such purchase money, or any part thereof,
or in any manner whatsoever be answerable for any loss, misapplication or
nonapplication of any such purchase money, or any part thereof, or be bound to
inquire as to the authorization, necessity, expediency or regularity of such
sale.

     (g)  The Agent shall not incur any liability as a result of the manner of
sale of the Collateral, or any part thereof, at any private sale conducted in a
commercially reasonable manner. The Company hereby waives, to the full extent
permitted by applicable law, any claims against the Agent or the Secured Parties
arising by reason of the fact that the price at which the Collateral, or any
part thereof, may have been sold at a private sale was less than the price which
might have been obtained at a public sale or was less than the aggregate amount
of the Secured Obligations, even if the Agent accepts the first offer received,
which the Agent in good faith deems to be commercially reasonable under the
circumstances and does not offer the Collateral to more than one offeree.  To
the extent permitted by law, the Company shall have the burden of proving that
any such sale of the Collateral was conducted in a commercially unreasonable
manner.

     (h)  Each and every right and remedy of the Agent shall, to the extent
permitted by law, be cumulative and shall be in addition to any other remedy
given hereunder or under the Credit Agreement or any other Project Document or
now or hereafter existing at law or in equity or by statute.

Agreement (including enforcement of this Agreement and any claims, losses and

     -------------                                                      
resulting from the gross negligence, bad faith or willful misconduct of such
Person) or (ii) any refund or adjustment (other than any refund or adjustment
ordered or required as a result of the gross negligence, bad faith or willful
misconduct of any Secured Party) of any amount paid or payable to the Agent
under or in respect of any of the Assigned Agreements, or any interest thereon,
which may be ordered or otherwise required by any Person.

     (b)  The Company shall, upon demand, pay to the Agent the amount of any and
all reasonable expenses (together with interest thereon at a rate per annum
equal to the sum of the ABR Rate plus 2%), including the reasonable fees and
expenses of counsel and of any experts and agents, which the Agent may incur
following the occurrence and during the continuance of a Default in connection
with (i) the administration of this Agreement, (ii) the custody or preservation
of, or the collection from or other realization upon, any of the Collateral,
(iii) the exercise or enforcement of any of the rights of the Agent hereunder or
(iv) the failure by the Company to perform or observe any of the provisions
hereof.

     (c)  In any suit, proceeding or action brought by the Agent or any Secured
Party under any Assigned Agreement or for any sum owing thereunder, or to
enforce any provisions of such Assigned Agreement, the Company will save,
indemnify, and hold the Agent and the Secured Parties harmless from and against
any and all expenses, losses or damages suffered by reason of any defense, set-
off, counterclaim, recoupment or reduction of liability whatsoever of the other
party under such Assigned Agreement arising out of a breach by the Company of
any obligation to the other party under such Assigned Agreement or arising out
of any other agreement, indebtedness or liability at any time owing to or in
favor of such other party or successors from the Company, and all such
obligations of the Company shall be and remain enforceable against and only
against the Company and shall not be enforceable against the Agent or the
Secured Parties.

     SECTION 21.  Amendments; etc.  No amendment, modification or waiver of any
                  ----------------                                             
provision of this Agreement nor consent to any departure by the Company herefrom
shall in any event be effective unless the same shall be in writing and signed

and for the specific purpose for which given.

     SECTION 23.  Continuing Assignment and Security Interest.  (a)  This
                  -------------------------------------------            
Agreement shall create a continuing assignment of and security interest in the
Collateral and shall (i) remain in full force and effect until termination of

interest granted hereby shall terminate, and all rights to the Collateral shall,
subject to any other security interest applicable thereto, revert to the
Company.  Upon any such termination, the Agent will, at the Company's expense,

     (c)  As used in Section 23(b), the term "Termination Date" shall mean the

transfer or otherwise furnish to the Agent (to the extent so assignable or
transferable) or to any transferee of the interest of the Agent, all of the
Company's rights and interest in, to and under all Permits, offsets and similar
rights issued under or in connection with any Environmental Law, including
Permits respecting air emissions (including air emission reduction credits or
offsets), wastewater discharge, and solid or hazardous waste management, which

efforts to have renewed or extended in the name of the Agent (or other Person
operating the Project) or otherwise to obtain for the Agent (or such other
Person) the benefits of all of the Permits and other rights referred to in the

the maximum amount included within the Liabilities on account of principal shall
not exceed the sum of an amount equal to two times the Credit Amount plus the
total amount of all advances made by the Mortgagee to protect the Collateral and
the security interest and lien created hereby); (vi) interest on all of the
foregoing; (vii) and all costs (including, without limitation, attorneys' fees
and expenses) of enforcement and collection of this Mortgage and the other

          ------------                                                   
Mortgagor will not:  (i) sell, assign, transfer, convey, lease or otherwise

otherwise disposed of, the Collateral or any part thereof or any interest
(whether legal, beneficial or otherwise) or estate in any thereof; (ii) remove

those of current taxes not delinquent and the Permitted Liens; provided that the
                                                               --------         
Mortgagor may sell the Premises (subject to the Lien of this Mortgage) to the
County subject to the simultaneous execution 

                                      -7-
<PAGE>
 
and delivery of the Bond Lease; provided further that such sale to the County
                                -------- ------- 
shall not release the Mortgagor in any respect from its obligations hereunder.

     5.   Access by Mortgagee.  The Mortgagor will at all times permit the
          -------------------                                             
Mortgagee and its agents and designees, at all reasonable times, to enter on and
inspect the Premises.

     6.   Stamp and Other Taxes.  If the Federal, or any state, county, local,
          ---------------------                                               
municipal or other, government or any subdivision of any thereof having
jurisdiction, shall levy, assess or charge any tax (excepting therefrom any
income tax on the Mortgagee's receipt of interest payments on the principal
portion of the indebtedness secured hereby), assessment or imposition upon this
Mortgage, the Liabilities or any of the other Credit Documents, the interest of
the Mortgagee in the Collateral, or any of the foregoing, or upon the Mortgagee
by reason of or as holder of any of the foregoing, or shall at any time or times
require revenue stamps to be affixed to this Mortgage, or any of the other
Credit Documents, the Mortgagor shall pay all such taxes and stamps to or for
the Mortgagee as they become due and payable in accordance with the Credit
Agreement.  If any law or regulation is enacted or adopted permitting,
authorizing or requiring any such tax, assessment or imposition to be levied,
assessed or charged, which law or regulation prohibits the Mortgagor from paying
such tax, assessment, stamp, or imposition to or for the Mortgagee, then such
event shall constitute a Default hereunder and all sums hereby secured shall
become immediately due and payable at the option of the Mortgagee.

     7.   Insurance.  The Mortgagor will at all times maintain (or caused to be
          ---------                                                            
maintained) on the Goods, the Improvements and on all other Collateral, all
insurance required at any time or from time to time by the Mortgagee or by the
provisions of the Credit Agreement and the Bond Lease and in any event fire and
extended coverage insurance for the benefit of the Mortgagee, to the full extent
of the Mortgagee's interest therein, against loss or damage (whether to such
Collateral or Improvements or by loss of rentals, business interruption, loss of
occupancy or other damage therefrom) from such hazards as may be required by the
Mortgagee pursuant to the Credit Agreement.  The Mortgagor agrees that any loss
paid to the Mortgagee under any of such policies of property or casualty (but
not including business or rental interruption) insurance shall be applied in the
manner set forth in the Credit Agreement.

     8.   Eminent Domain.  In case the Collateral, or any part or interest in
          --------------                                                     
any thereof, is the subject of a Taking, all condemnation awards or other
compensation paid as a result thereof (all of which the Mortgagor hereby assigns
to the Mortgagee), shall be forthwith applied in the manner set forth in the
Credit Agreement.

     9.   Governmental Requirements.  The Mortgagor will at all times fully
          -------------------------                                        
comply in all material respects with, and cause the Collateral and the use and
condition thereof fully to comply with, all federal, state, county, municipal,
local and other governmental statutes, 

                                      -8-
<PAGE>
 
ordinances, requirements, regulations, rules, orders and decrees of any kind
whatsoever that apply or relate to the Mortgagor or the Collateral or the use
thereof, and will observe and comply with all conditions and requirements
necessary to preserve and extend any and all rights, licenses, permits,
privileges, franchises and concessions (including, without limitation, those
relating to land use and development, landmark preservation, construction,
access, water rights and use, noise and pollution) which are applicable to the
Mortgagor or have been granted for the Collateral or the use thereof, all in
accordance with the Credit Agreement.

     10.  No Mechanics' Liens.  The Mortgagor will use its best efforts not to
          -------------------                                                 
do or permit to be done any act or thing whereby any mechanics' lien under the
laws of the State of Arkansas can arise against or attach to the Premises or any
part thereof unless such lien shall first be wholly waived as against this
Mortgage; provided that, if any such lien should be filed the Mortgagor will use
          --------                                                              
its best efforts to have any such lien removed within 21 days after the date the
Mortgagor learns of such lien.  In addition, it is further expressly made a
covenant and condition hereof that the lien of this Mortgage shall extend to any
and all improvements and fixtures now or hereafter on the Premises, prior to any
other lien thereon that may be claimed by any person, so that subsequently
accruing claims for lien on the Premises shall be junior and subordinate to this
Mortgage.  TO THE EXTENT PROVIDED BY LAW, ALL CONTRACTORS, SUBCONTRACTORS, AND
OTHER PARTIES DEALING WITH THE PREMISES, OR WITH ANY PARTIES INTERESTED THEREIN,
ARE HEREBY REQUIRED TO TAKE NOTICE OF THE ABOVE PROVISIONS.

     11.  Continuing Priority.  The Mortgagor will: (i) pay such fees, taxes and
          -------------------                                                   
charges, execute and file (at the Mortgagor's expense) such financing
statements, obtain such acknowledgments or consents, notify such obligors or
providers of services and materials and do all such other acts and things as the
Mortgagee may from time to time request to establish and maintain a valid and
perfected first and prior lien on and security interest in the Collateral and to
provide for payment to the Mortgagee directly of all cash proceeds thereof, with
the Mortgagee in possession of the Collateral to the extent it requests; (ii)
maintain its executive office and principal place of business at all times at
the address shown above; (iii) keep all of its books and records relating to the
Collateral on the Premises or at such address; (iv) keep all tangible Collateral
on the Real Estate except as the Mortgagee may otherwise consent in writing; (v)
make notations on its books and records sufficient to enable the Mortgagee, as
well as third parties, to determine the interest of the Mortgagee hereunder; and
(vi) not collect any rents or the proceeds of any of the Leases or Intangibles
more than 30 days before the same shall be due and payable except as the
Mortgagee may otherwise consent in writing, all in accordance with the Credit
Documents.

     12.  Utilities.  The Mortgagor will pay all utility charges incurred in
          ---------                                                         
connection with the Collateral and maintain all utility services available for
use at the Premises.

                                      -9-
<PAGE>
 
     13.  Contract Maintenance; Other Agreements.  The Mortgagor will, in
          --------------------------------------                         
accordance with the Credit Agreement, for the benefit of the Mortgagee, fully
and promptly perform each obligation and satisfy each condition imposed on it
under the Bond Lease, any Contract for Sale, Contract for Construction, Project
Contract, Lease, Intangible or other agreement so that there will be no default
thereunder and so that the persons (other than the Mortgagor) obligated thereon
shall be and remain at all times obligated to perform for the benefit of the
Mortgagee; and the Mortgagor will not permit to exist any condition, event or
fact which could allow or serve as a basis or justification for any such person
to avoid such performance.

     14.  Agreements Affecting the Collateral.  The Mortgagor shall keep,
          -----------------------------------                            
observe, perform and comply with all covenants, conditions and restrictions
affecting the Premises, any operating agreements or other writings relating to
the Collateral, and all leases, instruments and documents relating thereto or
evidencing or securing any indebtedness secured thereby, all in accordance with
the Credit Agreement.

     15.  No Assignments; Future Leases; Assignment of Rents.  Except as
          --------------------------------------------------            
permitted by the Credit Agreement, the Mortgagor will not cause or permit any
Rents, issues, profits, the Bond Lease, Leases, Contracts for Sale, or other
contracts relating to the Premises, or any interest in any thereof, to be
assigned, transferred, conveyed, pledged or disposed of, to any party other than
the Mortgagee without first obtaining the express written consent of the
Mortgagee thereto which consent may be granted or withheld in the sole
discretion of the Mortgagee.  In addition, the Mortgagor shall not cause or
permit all or any portion of or interest in the Premises or the Improvements to
be leased (that word having the same meaning for purposes hereof as it does in
the law of landlord and tenant) directly or indirectly to any person, except
with the prior written consent of the Mortgagee, which consent may be granted or
withheld in the sole discretion of the Mortgagee.

     The Mortgagor does hereby grant, bargain, sell, assign, transfer and set
over to the Mortgagee, all of the rents, income, proceeds and benefits under the
Leases; provided, however, that permission is hereby given to the Mortgagor,
unless a Default has occurred and is continuing and the Mortgagee has given
notice to the Mortgagor, to collect, receive, and apply the Rents, proceeds
thereof and other rents, income, proceeds and benefits as they become due and
payable, but not in advance thereof, and in accordance with all of the other
terms, conditions and provisions hereof, the Credit Documents and of the Leases,
contracts, agreements and other instruments with respect to which such payments
are made or such other benefits are conferred.  Upon the occurrence of and
during the continuance of a Default, such permission shall terminate immediately
upon notice from the Mortgagee, and once so terminated shall not be reinstated
upon a cure of such Default without the express written consent of the
Mortgagee.  Such assignment shall be fully effective without any further action
on the part of the Mortgagor or the Mortgagee and the Mortgagee shall be
entitled, in accordance with the Credit Documents, upon the occurrence of and
during the continuance of a Default hereunder, upon notice to the 

                                     -10-
<PAGE>
 
Mortgagor, to collect, receive and apply all Rents, Proceeds and all other
rents, income, proceeds and benefits from the Collateral, including all right,
title and interest of the Mortgagor in any escrowed sums or deposits or any
portion thereof or interest therein, whether or not the Mortgagee takes
possession of the Collateral or any part thereof.

     16.  Collections.  Until such time as the Mortgagee shall notify the
          -----------                                                    
Mortgagor of the revocation of such power and authority, the Mortgagor will, at
its own expense, endeavor to collect, as and when due, all amounts due with
respect to any of the Rents, Leases, Contracts for Sale, Intangibles and other
Collateral, including the taking of such action with respect to such collection
as the Mortgagee may reasonably request, or, in the absence of such request, as
the Mortgagor may deem advisable.  The Mortgagee, however, may, at any time,
whether before or after any Default or any revocation of such power and
authority or the maturity of any of the Liabilities, notify any parties
obligated on any of the Rents, Leases, Contracts for Sale, Intangibles and other
Collateral to make payment to the Mortgagee of any amounts due or to become due
thereunder and enforce collection of any of the Rents, Leases, Contract for
Sale, Intangibles or other Collateral by suit or otherwise and surrender,
release or exchange all or any part thereof, or compromise or extend or renew
for any period (whether or not longer than the original period) any indebtedness
thereunder or evidenced thereby.  Upon request of the Mortgagee, the Mortgagor
will, in accordance with the Credit Documents, at its own expense, notify any
parties obligated on any of the Rents, Leases, Contracts for Sale, Intangibles
or other Collateral to make payment to the Mortgagee of the amounts due or to
become due thereunder.  Except as the Mortgagee may otherwise consent in
writing, the Mortgagor will, in accordance with the Credit Documents, forthwith,
upon receipt, transmit and deliver to the Mortgagee, in the form received, all
cash, checks, drafts, chattel paper and other instruments or writings for the
payment of money (properly endorsed, where required, so that such items may be
collected by the Mortgagee) which may be received by the Mortgagor at any time
in full or partial payment or otherwise as proceeds of any of the Collateral.
Any such items which may be received by the Mortgagor will not be commingled
with any other of its funds or property, but will be held separate and apart
from its own funds or property and upon express trust for the Mortgagee until
delivery is made to the Mortgagee. The Mortgagee is authorized to endorse, in
the name of the Mortgagor, any item, howsoever received by it, representing any
payment on or other proceeds of any of the Collateral and to endorse and
deliver, in the name of the Mortgagor, any instrument, chattel paper or other
item of Collateral held by the Mortgagee hereunder, in connection with the sale
or collection of Collateral, in accordance with the Credit Documents.  The
Mortgagor hereby irrevocably appoints the Mortgagee as the Mortgagor's attorney-
in-fact to exercise and perform any or all of the foregoing rights and duties.

     17.  Mortgagee's Performance.  If the Mortgagor fails to pay or perform any
          -----------------------                                               
of its obligations herein contained (including payment of expenses of
foreclosure and court costs), the Mortgagee may (but need not), as agent or
attorney-in-fact of the Mortgagor, after giving the Mortgagor notice of its
intention to do so (no such notice need be given 

                                     -11-
<PAGE>
 
after the occurrence of a Default), make any payment or perform (or cause to be
performed) any obligation of the Mortgagor hereunder, in any form and manner
deemed expedient by the Mortgagee, and any amount so paid or expended (plus
reasonable compensation to the Mortgagee for its out-of-pocket and other
expenses for each matter for which it acts under this Mortgage), with interest
thereon at the rate applicable after maturity as provided in the Credit
Agreement, shall be added to the principal debt hereby secured and shall be
repaid to the Mortgagee upon demand. By way of illustration and not in
limitation of the foregoing, the Mortgagee may (but need not) do all or any of
the following: (i) make payments of principal or interest or other amounts on
any lien, encumbrance or charge on any of the Collateral; (ii) make payments
under the Bond Lease; (iii) complete construction; (iv) make repairs; (v)
collect rents; (vi) prosecute collection of the Collateral or proceeds thereof;
(vii) purchase, discharge, compromise or settle any tax lien or any other lien,
encumbrance, suit, proceeding, title or claim thereof; (viii) contest any tax or
assessment; and (ix) redeem from any tax sale or forfeiture affecting the
Premises. In making any payment or securing any performance relating to any
obligation of the Mortgagor hereunder, the Mortgagee shall (as long as it acts
in good faith) be the sole judge of the legality, validity and amount of any
lien or encumbrance and of all other matters necessary to be determined in
satisfaction thereof. No such action of the Mortgagee shall ever be considered
as a waiver of any right accruing to it on account of the occurrence of any
matter which constitutes a Default (defined hereinafter).

     18.  Subrogation.  To the extent that the Mortgagee, on or after the date
          -----------                                                         
hereof, pays any sum due under any provision of law or any instrument or
document creating any lien prior or superior to the lien of this Mortgage, or
the Mortgagor or any other person pays any such sum with the proceeds of the
Loan, the Mortgagee shall have and be entitled to a lien on the Collateral equal
in priority to the lien discharged, and the Mortgagee shall be subrogated to,
and receive and enjoy all rights and liens possessed, held or enjoyed by, the
holder of such lien, which shall remain in existence and benefit the Mortgagee
in securing the Liabilities.  Without limiting the generality of the foregoing,
and in addition thereto (rather than in limitation thereof), the Mortgagee shall
be subrogated to the liens of all other mortgages, trust deeds, superior titles,
vendors' liens, liens, charges, encumbrances, rights and equities on the
Premises, to the extent that either (i) any obligation under any thereof is paid
or discharged with proceeds of disbursements or advances under the Credit
Agreement or of other indebtedness secured hereby or (ii) the release thereof
was granted or delivered in complete or partial consideration for the granting
of this Mortgage.

     19.  Hazardous Materials.  The Mortgagor hereby reaffirms all
          -------------------                                     
representations, warranties and covenants made by the Mortgagor with respect to
environmental matters in the Credit Agreement.

     20.  Mortgagor's Right to Contest.  The Mortgagor may contest or object to
          ----------------------------                                         
the legal validity or amount of any tax in accordance with the Credit Agreement
or any 

                                     -12-
<PAGE>
 
mechanics' or materialmen's lien on the Premises on and subject to the following
conditions: (i) After having given the Mortgagee at least five business days'
prior written notice of its intention to institute such proceedings, the
Mortgagor shall in good faith have instituted appropriate legal proceedings with
respect thereto, the pendency of which shall have the legal effect of staying
the effectiveness and enforcement of such taxes or lien (as the case may be) and
any and all other remedies relating thereto which may affect the Premises or the
title thereto, and the Mortgagor shall at all times thereafter prosecute such
proceedings diligently and in good faith to completion; (ii) the Mortgagor shall
either (A) have duly paid the full amount of the tax or lien under protest or
(B) have fully bonded over or title-insured over such tax or lien to the
Mortgagee's full satisfaction; and (iii) the Mortgagee shall have notified the
Mortgagor that the Mortgagee is satisfied that the validity, priority, value and
utility of its lien and security interest on and in the Collateral will not be
adversely affected by such contest, objection or proceedings.


                      II.  D E F A U L T; R E M E D I E S

     The Mortgagor and the Mortgagee hereby agree further as follows:

     1.   Defaults; Acceleration.  The occurrence of an Event of Default under
          ----------------------                                              
any of the Credit Documents shall constitute a "Default" hereunder.  Upon the
occurrence of any Default, the entire indebtedness pursuant to the Credit
Agreement and all other Liabilities, together with interest thereon at the rate
applicable after maturity as provided in the Credit Agreement, shall become and
be immediately due and payable in accordance with the Credit Agreement.

     2.   Remedies Cumulative.  No remedy or right of the Mortgagee hereunder or
          -------------------                                                   
under the Credit Agreement or any other Security Documents or otherwise, or
available under applicable law, shall be exclusive of any other right or remedy,
but each such remedy or right shall be in addition to every other remedy or
right now or hereafter existing under any such document or under applicable law.
No delay in the exercise of, or omission to exercise, any remedy or right
accruing on any Default shall impair any such remedy or right or be construed to
be a waiver of any such Default or an acquiescence therein, nor shall it affect
any subsequent Default of the same or a different nature.  Every such remedy or
right may be exercised concurrently or independently, and when and as often as
may be deemed expedient by the Mortgagee.  All obligations of the Mortgagor, and
all rights, powers and remedies of the Mortgagee, expressed herein shall be in
addition to, and not in limitation of, those provided by law or in the Credit
Agreement or the Security Documents or any other written agreement or instrument
relating to any of the Liabilities or any security therefor.

                                     -13-
<PAGE>
 
     3.   Possession of Premises; Remedies under Credit Agreement.  The
          -------------------------------------------------------      
Mortgagor hereby waives all right to the possession, income, and rents of the
Premises from and after the occurrence of any Default, and, in accordance with
the Credit Agreement, the Mortgagee is hereby expressly authorized and
empowered, at and following any such occurrence, to enter into and upon and take
possession of the Premises or any part thereof, to complete any construction in
progress thereon at the expense of the Mortgagor, to lease the same, to collect
and receive all Rents and to apply the same, less the necessary or appropriate
expenses of collection thereof, either for the care, operation and preservation
of the Premises or, at the election of the Mortgagee in its sole and
unreviewable discretion, to a reduction of such of the Liabilities in such order
as the Mortgagee may elect.  The Mortgagee, in addition to the rights provided
under the Credit Agreement, is also hereby granted full and complete authority
to enter upon the Premises, employ watchmen to protect the Goods and
Improvements from depredation or injury and to preserve and protect the
Collateral, and to continue any and all outstanding contracts for the
construction and completion of Improvements to the Premises, to make and enter
into any contracts and obligations wherever necessary in its own name, and to
pay and discharge all debts, obligations and liabilities incurred thereby, all
at the expense of the Mortgagor.  All such expenditures by the Mortgagee shall
be Liabilities under this Mortgage for all purposes.  Upon the occurrence of any
Default, the Mortgagee may also exercise any or all rights or remedies under the
Credit Agreement.

     4.   Foreclosure; Receiver.  Upon the occurrence of any Default, the
          ---------------------                                          
Mortgagee shall also have the right, in accordance with the Credit Agreement,
immediately or at any time thereafter (in the Mortgagee's sole discretion), to
foreclose this Mortgage.  Upon the filing of any complaint for that purpose, the
court in which such complaint is filed shall, upon application of the Mortgagee
or at any time thereafter, either before or after foreclosure sale, and without
notice to the Mortgagor or to any person claiming under or through the Mortgagor
and without regard to the solvency or insolvency at the time of such application
of any person then liable for the payment of any of the Liabilities, without
regard to the then value of the Premises or whether the same shall then be
occupied, in whole or in part, as a homestead, by the owner of the equity of
redemption, and without regarding any bond from the complainant in such
proceedings, appoint a receiver for the benefit of the Mortgagee (and the
Mortgagor hereby irrevocably and unconditionally agrees and consents to the
appointment of any such receiver that the Mortgagee may designate or request or
that such court may appoint), with power to take possession, charge, and control
of the Premises, to lease the same, to keep the buildings thereon insured and in
good repair, and to collect all Rents during the pendency of such foreclosure
suit and during any period from the appointment of the receiver up to and
including the date of the confirmation of sale.  The court may, from time to
time, authorize said receiver to apply the net amounts remaining in his hands,
after deducting reasonable compensation for the receiver and his counsel as
allowed by the court, in payment (in whole or in part) of any or all of the
Liabilities, including without limitation the following, in such order of
application as the Mortgagee in its sole and unreviewable discretion may 

                                     -14-
<PAGE>
 
elect: (i) amounts due upon the Loans and Letters of Credit, (ii) amounts due
upon any decree entered in any suit foreclosing this Mortgage, (iii) costs and
expenses (including, without limitation, attorneys' fees and expenses) of
foreclosure and litigation upon the Premises, (iv) insurance premiums, repairs,
taxes, special assessments, water charges and interest, penalties and costs, in
connection with the Premises, (v) any other lien or charge upon the Premises
that may be or become superior to the lien of this Mortgage, or of any decree
foreclosing the same and (vi) all moneys advanced by the Mortgagee to cure or
attempt to cure any default by the Mortgagor in the performance of any
obligation or condition contained in the Credit Agreement, the Security
Documents or this Mortgage or otherwise, to protect the security hereof provided
herein, in the Credit Agreement or in any of the Security Documents, with
interest on such advances at the interest rate applicable after maturity under
the Credit Agreement. The surplus of the proceeds of sale, if any, shall then
(to the fullest extent permitted by applicable law) be paid to the Mortgagor
(and, if not permitted by law to be paid to the Mortgagor, such surplus shall be
paid and applied as required by applicable law). This Mortgage may be foreclosed
once against all, or successively against any portion or portions, of the
Premises, as the Mortgagee may elect, until all of the Premises have been
foreclosed against and sold. In case of any foreclosure of this Mortgage (or the
commencement of or preparation therefor) in any court, all expenses of every
kind paid or incurred by the Mortgagee for the enforcement, protection or
collection of this security, including court costs, attorneys' fees,
stenographers' fees, costs of advertising, and costs of title insurance and any
other documentary evidence of title, shall be paid by the Mortgagor.

     5.   Assignment of Rents; Remedies for Leases and Rents.  If any Default
          --------------------------------------------------                 
occurs, then, whether before or after institution of legal proceedings to
foreclose the lien of this Mortgage or before or after the sale thereunder, the
Mortgagee shall be entitled, in its discretion in accordance with the Credit
Agreement, to do all or any of the following:  (i) enter and take actual
possession of the Premises, the Rents, the Leases and other Collateral relating
thereto or any part thereof personally, or by its agents or attorneys, and
exclude the Mortgagor therefrom; (ii) with or without process of law, enter upon
and take and maintain possession of all of the documents, books, records, papers
and accounts of the Mortgagor relating thereto; (iii) as attorney-in-fact or
agent of the Mortgagor, or in its own name as mortgagee and under the powers
herein granted, hold, operate, manage and control the Premises, the Rents, the
Leases and other Collateral relating thereto and conduct the business, if any,
thereof either personally or by its agents, contractors or nominees, with full
power to use such measures, legal or equitable, as in its discretion or in the
discretion of its successors or assigns may be deemed proper or necessary to
enforce the payment of the Rents, the Leases and other Collateral relating
thereto (including actions for the recovery of rent, actions in forceable
detainer and actions in distress of rent); (iv) cancel or terminate any Lease or
sublease for any cause or on any ground which would entitle the Mortgagor to
cancel the same; (v) elect to disaffirm any Lease or sublease made subsequent
hereto or subordinated to the lien hereof; (vi) make all necessary or proper
repairs, decoration, renewals, replacements, alterations, additions, 

                                     -15-
<PAGE>
 
betterments and improvements to the Premises that, in its discretion, may seem
appropriate; (vii) insure and reinsure the Collateral for all risks incidental
to the Mortgagee's possession, operation and management thereof; and (viii)
receive all such Rents and proceeds, and perform such other acts in connection
with the management and operation of the Collateral, as the Mortgagee in its
discretion may deem proper, the Mortgagor hereby granting the Mortgagee full
power and authority to exercise each and every one of the rights, privileges and
powers contained herein at any and all times after any Default without notice to
the Mortgagor or any other person. The Mortgagee, in the exercise of the rights
and powers conferred upon it hereby, shall have full power to use and apply the
Rents to the payment of or on account of the following, in such order as it may
determine: (a) to the payment of the operating expenses of the Premises,
including the cost of management and leasing thereof (which shall include
reasonable compensation to the Mortgagee and its agents or contractors, if
management be delegated to agents or contractors, and it shall also include
lease commissions and other compensation and expenses of seeking and procuring
tenants and entering into Leases), established claims for damages, if any, and
premiums on insurance hereinabove authorized; (b) to the payment of taxes,
charges and special assessments, the costs of all repairs, decorating, renewals,
replacements, alterations, additions, betterments and improvements of the
Collateral, including the cost from time to time of installing, replacing or
repairing the Collateral, and of placing the Collateral in such condition as
will, in the judgment of the Mortgagee, make it readily rentable; and (c) to the
payment of any Liabilities.

     6.   Performance of Contracts.  The Mortgagee may, in its sole discretion
          ------------------------                                            
at any time after the occurrence of a Default in accordance with the Credit
Agreement, notify any person obligated to the Mortgagor under or with respect to
any Intangible, any Contract for Sale or any Contract for Construction of the
existence of a Default, require that performance be made directly to the
Mortgagee at the Mortgagor's expense, and advance such sums as are necessary or
appropriate to satisfy the Mortgagor's obligations thereunder; and the Mortgagor
agrees to cooperate with the Mortgagee in all ways reasonably requested by the
Mortgagee (including the giving of any notices requested by, or joining in any
notices given by, the Mortgagee) to accomplish the foregoing.

     7.   No Liability on Mortgagee.  Notwithstanding anything contained in this
          -------------------------                                             
Mortgage, the Mortgagee shall not be obligated to perform or discharge, and does
not undertake to perform or discharge, any obligation, duty or liability of the
Mortgagor, whether under this Mortgage, under any of the Leases, under any
Intangible, under any Contract for Construction, under any Contract for Sale or
otherwise, and the Mortgagor shall and does hereby agree to indemnify against
and hold the Mortgagee harmless of and from: (i) any and all liabilities, losses
or damages which the Mortgagee may incur or pay under or with respect to any of
the Collateral or under or by reason of its exercise of rights hereunder; and
(ii) any and all claims and demands whatsoever which may be asserted against it
by reason of any alleged obligations or undertakings on its part to perform or
discharge any of the terms, covenants or agreements contained in any of the
Collateral 

                                     -16-
<PAGE>
 
or in any of the contracts, documents or instruments evidencing or creating any
of the Collateral, except for any liabilities, losses, damages, claims or
demands that arise from the Mortgagee's gross negligence or wilful misconduct.
The Mortgagee shall not have responsibility for the control, care, management or
repair of the Premises or be responsible or liable for any negligence in the
management, operation, upkeep, repair or control of the Premises resulting in
loss, injury or death to any tenant, licensee, employee, stranger or other
person. No liability shall be enforced or asserted against the Mortgagee in its
exercise of the powers herein granted to it, and the Mortgagor expressly waives
and releases any such liability. Should the Mortgagee incur any such liability,
loss or damage under any of the Leases or under or by reason hereof, or in the
defense of any claims or demands, the Mortgagor agrees to reimburse the
Mortgagee immediately upon demand for the full amount thereof, including costs,
expenses and attorneys' fees.

                              III  G E N E R A L

     1.   Permitted Acts.  The Mortgagor agrees that, without affecting or
          --------------                                                  
diminishing in any way the liability of the Mortgagor or any other person
(except any person expressly released in writing by the Mortgagee) for the
payment or performance of any of the Liabilities or for the performance of any
obligation contained herein or affecting the lien hereof upon the Collateral or
any part thereof, the Mortgagee may at any time and from time to time, without
notice to or the consent of any person, do any or all of the following: (i)
release any person liable (whether directly or indirectly, primarily or
secondarily, or otherwise) for the payment or performance of any of the
Liabilities; (ii) extend the time for, or agree to alter the terms of payment
of, any indebtedness under the Credit Agreement or any of the Liabilities; (iii)
modify or waive any obligation or performance; (iv) subordinate, modify or
otherwise deal with the lien hereof; (v) accept additional security of any kind;
(vi) release any Collateral or other property securing any or all of the
Liabilities; (vii) make releases of any portion of the Premises; (viii) consent
to the making of any map or plan of the Premises; (ix) consent to the creation
of a condominium regime on all or any part of the Premises, or to the creation
of any easements on the Premises or of any covenants restricting the use or
occupancy thereof; or (x) exercise or refrain from exercising, or waive, any
right the Mortgagee may have.

     2.   Suits and Proceedings.  The Mortgagor agrees to indemnify the
          ---------------------                                        
Mortgagee, and hold the Mortgagee harmless, from and against any and all losses,
damages, costs, expenses and claims of any kind whatsoever (including, without
limitation, attorneys' fees) which the Mortgagee may pay or incur in connection
with any suit or proceeding in or to which the Mortgagee may be made or become a
party, which suit or proceeding does or may affect all or any portion of the
Collateral or the value, use or operation thereof or this Mortgage or the
validity, enforceability, lien or priority hereof or of any of the Liabilities
or indebtedness secured hereby.

     3.   Credit Agreement; Construction Mortgage; Obligatory Future Advances.
          ------------------------------------------------------------------- 

          (a) The Mortgagor covenants that it will timely and fully perform and
     satisfy all the terms, covenants and conditions of the Credit Agreement and
     the Bond Lease in accordance with the terms thereof.

          (b) This Mortgage is granted to secure future advances and loans,
     including W/C Loans and LC Loans, from the Mortgagee and the Lenders to or
     for the benefit of the Mortgagor or the Premises, as provided in the Credit
     Agreement, regardless of whether, at the time or times of such advances,
     the Mortgagor is then the owner of the Collateral or any interest in any
     hereof, and costs and expenses of enforcing the Mortgagor's obligations
     under this Mortgage, the Credit Documents and the Credit Agreement.  All
     advances, disbursements or other payments required by the Credit Agreement
     are obligatory advances up to the credit limits established therein and
     shall, to the fullest extent permitted by law, have priority over any and
     all mechanics' liens and other liens and encumbrances arising after this
     Mortgage is recorded and shall be secured by this Mortgage.  Notice is
     hereby given that the indebtedness and Liabilities secured hereby may
     increase as a result of any defaults hereunder by the Mortgagor due to, for
     example, and without limitation, unpaid interest or late charges, unpaid
     taxes or insurance premiums which the Mortgagee elects to advance, defaults
     under leases that the Mortgagee elects to cure, attorney fees or costs
     incurred in enforcing the Loan Documents or other expenses incurred by the
     Mortgagee in protecting the Collateral, the security of this Mortgage or
     the Mortgagee's rights and interests.

     4.   Partial Releases. While not presently contemplated, it is possible
          ----------------                                                  
that the Mortgagee may from time to time consent in writing to one or more
partial releases of the lien of this Mortgage as it applies to one or more parts
of the Premises, but no such release (or any other release) shall affect the
lien of this Mortgage on the remainder of the Premises.

     5.   Security Agreement and Financing Statement.  This Mortgage, to the
          ------------------------------------------                        
extent that it conveys, grants a security interest in, or otherwise deals with
personal property or with items of personal property which are or may become
fixtures, shall also be construed as a security agreement, and also as a
financing statement, under the Uniform Commercial Code as in effect in the State
of Arkansas, with the Mortgagor as Debtor (with its address as set forth above)
and with the Mortgagee as Secured Party (with its address as set forth above).

     6.   Defeasance.  Upon full payment of all indebtedness secured hereby and
          ----------                                                           
full payment, performance and satisfaction of all the Liabilities in accordance
with their respective terms and at the time and in the manner provided, and when
the Mortgagee has no further obligation (whether contingent, conditional or
otherwise) to make any advance, 

                                     -18-
<PAGE>
 
disbursement or payment of any kind or to extend any credit under or with
respect to the Credit Agreement, this conveyance shall be null and void, and
thereafter, upon demand therefor, an appropriate instrument of quitclaim
reconveyance or release shall in due course be made by the Mortgagee to the
Mortgagor at the Mortgagee's expense.

     7.   Notices.  Each notice, demand or other communication in connection
          -------                                                           
with this Mortgage shall be in writing and shall be given and served upon the
addressee thereof in the manner set forth in the Credit Agreement.

     8.   Successors; The Mortgagor; Gender.  All provisions hereof shall inure
          ---------------------------------                                    
to and bind the parties and their respective successors, vendees and assigns;
provided, however, that the foregoing shall not in any way limit, restrict or
modify the provisions of Article I, Section 4 above.  The word "Mortgagor" shall
include all persons claiming under or through the Mortgagor and all persons
liable for the payment or performance of any of the Liabilities whether or not
such persons shall have executed the Credit Agreement or this Mortgage. Wherever
used, the singular number shall include the plural, the plural the singular, and
the use of any gender shall be applicable to all genders.

     9.   Care by the Mortgagee.  The Mortgagee shall be deemed to have
          ---------------------                                        
exercised reasonable care in the custody and preservation of any of the
Collateral in its possession if it takes such action for that purpose as the
Mortgagor requests in writing, but failure of the Mortgagee to comply with any
such request shall not be deemed to be (or to be evidence of) a failure to
exercise reasonable care, and no failure of the Mortgagee to preserve or protect
any rights with respect to such Collateral against prior parties, or to do any
act with respect to the preservation of such Collateral not so requested by the
Mortgagor, shall be deemed a failure to exercise reasonable care in the custody
or preservation of such Collateral.

     10.  No Obligation on Mortgagee.  This Mortgage is intended only as
          --------------------------                                    
security for the Liabilities.  Anything herein to the contrary notwithstanding,
(i) the Mortgagor shall be and remain liable under and with respect to the
Collateral to perform all of the obligations assumed by it under or with respect
to each thereof, (ii) the Mortgagee shall have no obligation or liability under
or with respect to the Collateral by reason or arising out of this Mortgage and
(iii) the Mortgagee shall not be required or obligated in any manner to perform
or fulfill any of the obligations of the Mortgagor under, pursuant to or with
respect to any of the Collateral.

     11.  No Waiver by the Mortgagee; Writing.  No delay on the part of the
          -----------------------------------                              
Mortgagee in the exercise of any right or remedy shall operate as a waiver
thereof, and no single or partial exercise by the Mortgagee of any right or
remedy shall preclude other or further exercise thereof or the exercise of any
other right or remedy.  No amendment, waiver or supplement in any way affecting
this Mortgage shall in any event be effective unless set out in a writing signed
by the Mortgagee.

     12.  Governing Law; Severability; Section Headings.  This Mortgage has been
          ---------------------------------------------                         
executed and delivered at Chicago, Illinois, where the Mortgagee maintains its
principal place of business, and shall be construed in accordance with and
governed by the laws of the State of Illinois except for the lien rights and
remedies pertaining thereto which must be governed by the laws of the state in
which the premises are situated, regarding which Arkansas law shall govern.
Whenever possible, each provision of this Mortgage shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision
of this Mortgage shall be prohibited by or invalid under applicable law, such
provision shall be ineffective to the extent of such prohibition or invalidity
only, without invalidating the remainder of such provision or the remaining
provisions of this Mortgage, it being the parties' intention that this Mortgage
and each provision hereof be effective and enforced to the fullest extent
permitted by applicable law.  The Section headings used herein are for
convenience of reference only, and shall not be deemed to be a part of this
Mortgage or be considered in the interpretation, or construction thereof.

     13.  No Merger.  It being the desire and intention of the parties hereto
          ---------                                                          
that this Mortgage and the lien hereof do not merge in fee simple title to the
Premises, it is hereby understood and agreed that should the Mortgagee acquire
an additional or other interests in or to the Premises or the ownership thereof,
then, unless a contrary intent is manifested by the Mortgagee as evidenced by an
express statement to that effect in an appropriate document duly recorded, this
Mortgage and the lien hereof shall not merge in the fee simple title, toward the
end that this Mortgage may be foreclosed as if owned by a stranger to the fee
simple title.

     14.  Mortgagee Not a Joint Venturer or Partner.  The Mortgagor and the
          -----------------------------------------                        
Mortgagee acknowledge and agree that in no event shall the Mortgagee be deemed
to be a partner or joint venturer with the Mortgagor.  Without limitation of the
foregoing, the Mortgagee shall not be deemed to be such a partner or joint
venturer on account of its becoming a mortgagee in possession or exercising any

          -----------------------------------------------------     
consideration of the premises and of the elements of consideration recited in
the granting clause (i.e., the first paragraph following the caption "Grant")
                     ---                                                     
above, the Mortgagor hereby grants and conveys to the Mortgagee and its
successors and assigns until the Liabilities have been paid in full an easement
(the "Environmental Easement") to enter on, upon and within the Premises in
accordance with the Credit Agreement at any time and from time to time for the
purpose of making such tests, inspections, investigations and examinations
(including, without limitation, soil borings and tests and other subsurface
explorations, investigations, examinations and tests) as the Mortgagee, in its
discretion, deems necessary, convenient, or useful to enable it to determine (i)
whether any Hazardous Materials are or may be present on, under, upon or within
the Premises or any part thereof and (ii) whether the ownership, use, condition,
and operation of the Premises and the conduct of the activities engaged in
thereat are in compliance with federal, state, and local environmental laws,
rules, and regulations.  The Mortgagor hereby irrevocably grants to the
Mortgagee and its agents, contractors and designees the right, in accordance
with the Credit Agreement, to 

                                     -22-
<PAGE>
 
inspect and copy all of the Mortgagor's records relating to environmental
matters and to enter all buildings, improvements, and facilities of the
Mortgagor for such purpose. The Mortgagor hereby grants to the Mortgagee a
continuing security interest in and to all of the Mortgagor's existing and
future records that relate in any way to any environmental matters, whether
located at the Premises or elsewhere, whether in the possession or control of
the Mortgagor or any other person (including any federal, state, or local agency
or instrumentality), and whether written, photographic, computerized, or in any
other form, state or condition, and the proceeds and products thereof. The
Mortgagee or its agent, contractor or designee may, in accordance with the
Credit Agreement, interview any or all of the Mortgagor's agents, employees, and
independent contractors and consultants regarding environmental matters,
including any consultants or experts retained by the Mortgagor, all of whom are
hereby irrevocably authorized and directed by the Mortgagor to discuss
environmental issues fully and openly with the Mortgagee and its agents,
contractors and designees and to provide to them such information as may be
requested by any of them. All reasonable costs and expenses paid or incurred by
the Mortgagee pursuant to this Section 1 of Article IV for or with respect to
the tests, inspections, investigations and examinations which the Mortgagee may
conduct, including (without limitation) the fees and expenses of the Mortgagee's
consultants, engineers, laboratories, and contractors, shall be paid by the
Mortgagor on demand by the Mortgagee. The Mortgagee may, but shall not be
required to, advance such costs and expenses on behalf of the Mortgagor. All
sums so advanced shall bear interest at the highest rate provided with respect
to the Loan, and all such advances shall be deemed indebtedness owing under the
Credit Agreement and secured by the Security Documents.

     2.   Duration and Defeasance.  The Environmental Easement shall exist and
          -----------------------                                             
continue until such time as all of the Liabilities have been fully paid,
performed and satisfied, the Mortgagee has no further obligation to advance any
amounts to the Mortgagor under or with respect to the Credit Agreement or any of
the Credit Documents, and this Mortgage has been released of record.  A release
of this Mortgage shall also be deemed to constitute and evidence a termination
of the Environmental Easement.

     3.   Enforcement.  The Mortgagor (i) acknowledges that no adequate remedy
          -----------                                                         
at law exists for a violation of the Environmental Easement or for the
Mortgagor's failure or refusal to provide to the Mortgagee any or all of the
access, rights or other benefits set out or described in any provision of this
Article IV, and (ii) agrees that the Mortgagee shall have the right to enforce
the Environmental Easement and all of the other provisions of this Article IV by
any and all equitable writs, decrees, remedies and relief (including, without
limitation, temporary and preliminary injunctive relief).  The Mortgagor agrees
to pay all of the Mortgagee's costs and expenses of enforcement (including,
without limitation, court costs and attorneys' fees and expenses) of the
provisions of this Article IV.

     4.   Running with the Land; Assignability.  The Environmental Easement is
          ------------------------------------                                
intended to be and shall be construed as an interest in the Premises and as an
easement 

                                     -23-
<PAGE>
 
in gross; it is not intended to be a personal right of the Mortgagee or a mere
license. The Environmental Easement, and all rights and benefits of the
Mortgagee as set out in this Article IV, shall run with and bind the Land and
the Premises, shall be binding upon all successor owners of any and every estate
and interest in the Premises, and shall be deemed to have been assigned to and
be enforceable by and inure to the benefit of whomever holds the indebtedness
secured by this Mortgage.

     5.   Revocability.  The Environmental Easement is irrevocable.
          ------------                                             

     6.   Mortgagee not Mortgagee in Possession.  The exercise of the rights
          -------------------------------------                             
granted hereunder shall not constitute the Mortgagee a mortgagee in possession
with respect to the Premises.

     7.   Mortgagor's Understanding.  The Mortgagor acknowledges that it has
          -------------------------

any nature whatsoever that constitutes or might constitute an equitable or legal

Secured Party shall not result in the waiver of or affect or diminish any right
of the Agent at any time or times thereafter to demand strict performance of the
obligations applicable to any  hereunder and such right shall not be deemed to
have been waived by any act or knowledge of any Secured Party other than by a
specific written waiver by the appropriate Secured Parties.  No waiver by any
Secured Parties of any default or failure to pay when due all or any portion of
the obligations applicable to the Equity Owner hereunder shall operate as a
waiver of any other default or failure or the same default or failure on a
future occasion.  None of the Secured Parties shall have any liability for the
performance or observance of any of the obligations or duties of the Company

          -------------------------                                           
shall, if so requested by the Required Lenders, exercise any or all of the
rights and remedies provided in this Pledge Agreement or any other Credit
Document, in the Uniform Commercial Code as in effect in Illinois or by any
other applicable law. Without limiting the foregoing, whenever Pledgor Default
shall exist and be continuing the Agent (a) shall, if so requested by the
Required Lenders, to the fullest extent permitted by applicable law, without
notice, advertisement, hearing or process of law of any kind, (i) sell any or
all of the Collateral, free of all rights and claims of any Pledgor therein and
thereto, at any public or private sale or brokers' board and (ii) bid for and
purchase any or all of the Collateral at any such public sale; and (b) shall
have the right, for and in the name, place and stead of any Pledgor, to execute
endorsements, assignments, stock powers and other instruments of conveyance or
transfer with respect to all or any of the Collateral.  Each Pledgor hereby
expressly waives, to the fullest extent permitted by applicable law, any and all
notices, advertisements, hearings or process of law in connection with the
exercise by the Agent of any of its rights and remedies during the continuance
of a Pledgor Default.  If any notification of intended disposition of any of the
Collateral is required by law, such notification, if mailed, shall be deemed
reasonably and properly given if mailed by certified or registered mail at least
ten (10) days before such disposition, postage prepaid, addressed to any
Pledgor, either at the address of such Pledgor shown below, or at any other
address of such Pledgor appearing on the records of the Agent.  Any proceeds of
any of the Collateral may be applied by the Agent to the payment of expenses in
connection with the Collateral, including, without limitation, reasonable
attorneys' fees and legal expenses, and any balance of such proceeds may be
applied by the Agent toward the payment of such of the Liabilities, and in such
order of application, as the Agent may 

                                      -6-
<PAGE>
 
from time to time elect (and, after payment in full of all Liabilities, any
excess shall be delivered to the applicable Pledgor or as a court of competent
jurisdiction shall direct).

     The Agent is hereby authorized to comply with any limitation or restriction
in connection with any sale of Collateral as it may be advised by counsel is
necessary in order to (a) avoid any violation of applicable law (including,
without limitation, compliance with such procedures as may restrict the number
of prospective bidders and purchasers and/or further restrict such prospective
bidders or purchasers to persons or entities who will represent and agree that
they are purchasing for their own account for investment and not with a view to
the distribution or resale of such Collateral) or the loss of qualifying
facility status for the Facility or (b) obtain any required approval of the sale
or of the purchase by any governmental regulatory authority or official, and
each Pledgor agrees that such compliance shall not result in such sale being
considered or deemed not to have been made in a commercially reasonable manner
and that the Agent shall not be liable or accountable to such Pledgor for any
discount allowed by reason of the fact that such Collateral is sold in
compliance with any such limitation or restriction.

     5.2  Care of Collateral.  The Agent shall be deemed to have exercised
          ------------------                                              
reasonable care in the custody and preservation of the Collateral if it takes
such action for that purpose as any Pledgor shall request in writing, but
failure of the Agent to comply with any such request shall not of itself be
deemed a failure to exercise reasonable care, and no failure of the Agent to
preserve or protect any rights with respect to the Collateral against prior
parties, or to do any act with respect to preservation of the Collateral not so
requested by such Pledgor, shall be deemed of itself a failure to exercise
reasonable care in the custody or preservation of any Collateral.

     5.3  Sharing of Collateral.  The Secured Parties agree that the net
          ---------------------                                         
proceeds of any sale or disposition of the Collateral after the occurrence of a
Pledgor Default shall be distributed among the Secured Parties as set forth in
the Security Agreement.

     5.4  Registration of Collateral.  At the option of the Agent, any
          --------------------------                                  
registerable Collateral may at any time be registered in the name of the Agent

obligations of such Pledgor contained in this Pledge Agreement, that the
covenants of such Pledgor contained in the Sections referred to in this Section
                                                                        -------

demand for payment of any amount due pursuant to the Credit Agreement or the
other Credit Documents may be rescinded by the Secured Parties, or any of the
loans or other extensions of credit thereunder continued or such amounts, or the
liability of any other Person upon or for any part thereof, or any collateral
security or guaranty therefor or right of offset with respect thereto, may, from
time to time, in whole or part, be renewed, extended, amended, modified,
accelerated, compromised, waived, surrendered or released by the Secured
Parties, or the Credit Agreement, the Notes or any other Credit Documents or any
other document executed

Agent.

     7.4  Survival of Representations.  All representations and warranties of

acceptance hereof, shall not be deemed to have assumed or become liable for any
of the obligations or liabilities of each Pledgor under the LLC Agreement,
whether provided for by the terms thereof, arising by operation of law or
otherwise, and the Pledgor hereby acknowledges and agrees that such Pledgor is
